CDC Makes New Recommendations for Influenza Immunization

The Centers for Disease Control and Prevention (CDC) in August released this year’s recommendations on influenza vaccination, including some changes affecting young children and people with egg allergies.

This year’s vaccine targets the same three strains as last year: A/California/7/2009 (H1N1)-like, A/Perth/16/2009 (H3N2)-like, and B/Brisbane/60/2008-like antigens. Even though the vaccine is unchanged, CDC advises annual vaccination because levels of protective antibodies can decrease, especially in the elderly and people with compromised immune systems.

Experts have known for some time that children aged 6 months through 8 years require two doses of influenza vaccine during their first season of vaccination. This year, however, because the vaccine strains are unchanged, children in this age group who received at least one dose of the 2010-2011 vaccine will require only one dose of the 2011-2112 vaccine. Children in this age group who did not receive at least one dose last year or whose immunization status is uncertain should receive two doses.

Also new this year is more in-depth advice concerning people with egg allergies. Several recent studies have documented safe receipt of trivalent inactivated vaccine (TIV) in people with egg allergy, particularly those with less severe reactions. CDC now advises that people who have had only hives after exposure to eggs should receive TIV from providers who are familiar with egg allergy and should be observed for at least 30 minutes after vaccination to monitor for possible reactions. People who have had more serious reactions to eggs (e.g., angioedema, respiratory distress, lightheadedness, recurrent vomiting, or those who required emergency medical care) should consult with an allergist before receiving the vaccine.

Last year was the first year that CDC recommended universal influenza immunization for everyone over 6 months of age. With vaccine manufactures projecting to have between 166 million and 173 million doses of vaccine on the U.S. market this season, CDC says the supply should be ample in September and October.

EIN Update: CBC Monitoring for ID-Related Diseases

The Emerging Infections Network (EIN) is a forum for infectious diseases consultants and public health officials to report information on clinical phenomena and epidemiological issues with public health significance. Any diagnostic or therapeutic recommendations and all opinions presented are those of the individual contributor. They do not necessarily represent the views of EIN, IDSA (EIN’s sponsor), or the Centers for Disease Control and Prevention (CDC), which funds EIN. The reader assumes all risks in using this information.

EIN members recently discussed the appropriate use of non-microbiologic diagnostic tests, including complete blood counts (CBCs), for infectious diseases.

A member in Florida began the discussion, asking about “the necessity of frequent CBCs on hospitalized patients admitted with infectious diagnoses, for the most part general ID issues (not neutropenic or in the intensive care unit [ICU]). Under what circumstances would you want frequent CBC monitoring (i.e., aside from disseminated intravascular coagulation [DIC] from sepsis and hemolysis from infections such as malaria)?”

A respondent in Minnesota noted that “the same could be asked about inflammatory markers (erythrocyte sedimentation rate [ESR], C-reactive protein [CRP], procalcitonin). The trend curves look nice and make us feel good,” the member wrote. “But do they add meaningfully to the bedside clinical assessment?”

An EIN member in Canada reported CBC monitoring “not often and based mostly on clinical assessment first,” sometimes in cases of a fever not yet diagnosed, if the patient’s initial white blood count (WBC) was extremely high, if there is concern about development of hemolytic-uremic syndrome (HUS) in a patient with colitis, or with malaria.

“I've always thought that in general, we order too many CBCs and too many chemistry panels on stable patients,” a member in New Hampshire responded. “I’ll check a CBC more frequently when there are significant abnormalities to begin with (low platelets, for example), or when the patient has a high risk of other complications (septic patient in the ICU, not responding to treatment).”

Short of that, a CBC every two to three days while the patient is in-house is usually reasonable, the member continued, and “maybe not at all when following a patient with something like cellulitis or pneumonia, who is obviously improving and ready for oral antibiotics.”

Daily CBC or electrolyte monitoring do not make sense in regular day-to-day admissions, another member in Canada wrote, “and I don’t mean only for infectious disease related issues. Eventually, the iatrogenic drop in hemoglobin might change our clinical management, but this is avoidable.”

“The only time we ask for regular CBCs is when we treat our patients with long-term high-dose beta-lactam antibiotics (e.g., for osteomyelitis) to monitor drug-induced neutropenia,” the member noted, “and when we start an HIV-exposed newborn on azidothymidine (AZT) to monitor anemia, and this is at most a weekly CBC. I suppose that CBC monitoring with linezolid treatment is also warranted, but we haven’t needed to use this in children.”

For most uncomplicated infectious illnesses, two WBCs are needed, one to assist with initial diagnosis and/or to demonstrate that the patient is having the expected response, and another to document that the WBC is consistent with clinical recovery, an EIN member in Pennsylvania wrote.

“It’s not necessary to get daily WBCs (or chemistry panels or chest x-rays, etc.) in a patient with a solid clinical diagnosis who is clinically improving,” the member continued. “Many of our residents get daily labs regardless of the patient’s clinical progress. This is wasteful, expensive, hard on the patient’s antecubital fossae, and a barrier to learning the essentials of critical thinking.”

A respondent in Tennessee agreed: “‘Following the white count daily’ is almost never helpful in monitoring the clinical course of patients with infectious diseases. In situations where laboratory test results can provide additional evidence of adequate response to therapy, monitoring acute phase reactants, such as C-reactive protein, is much more likely to be of value.”

“Some doctors order daily CBC and differential when CBC without differential is often adequate in many non-ICU patients,” an EIN member in California responded. “We are often asked to do consults for leukocytosis and frequently find the reason.

A consensus on when CBC monitoring is appropriate could lead to savings, the member suggested, although “one would have to balance cost savings with fewer CBCs against missed changes in patient conditions with daily CBC that might interfere with patient care or eventually lead to higher costs.”

Armed with Research on Early HIV Treatment, HIVMA and Global Center Make Case for More Funding

The Center for Global Health Policy and HIVMA released a policy statement (PDF) this month, calling for greater investment domestically and globally in HIV treatment in light of the results of the HIV Prevention Trial Networks (HPTN) 052 study. The study found that early initiation of antiretroviral therapy (ART) for HIV-infected patients reduced their chances of sexually transmitting HIV to their uninfected partners by more than 96 percent.  

The Center and HIVMA recommend that a larger share of the President's Emergency Plan for AIDS Relief (PEPFAR) budget be devoted to treatment; that ART be included in studies of combination prevention strategies, and that HIV counseling and testing, including couples counseling, be expanded in all venues. The policy statement also calls for an evaluation of PEPFAR prevention expenditures based on evidence of efficacy and a redeployment of resources from less efficacious interventions to those known to be effective, including ART.

In addition, the groups call for prioritizing domestic HIV funding for early HIV diagnosis with reliable and ongoing linkage and access to HIV care and treatment; and for fully funding the Ryan White program and addressing state waiting lists for ART medication.

Congressional Staff Tours U.S.-funded HIV and TB programs in Kenya with Global Center

The Center for Global Health Policy hosted House and Senate staffers on a week-long trip to Kenya in August designed to give Hill staff a first-hand view of key HIV and tuberculosis (TB) programs that receive U.S. funding, the progress they are making, and why U.S. support is needed. The trip included stops in Nairobi to visit hospitals and clinics that serve Kibera’s impoverished neighborhoods, meetings with key Ministry of Health officials and civil society organizations, as well as clinical site visits in the more rural parts of the country, Kisumu, Kericho and Eldoret. Check out these posts from the trip on the Center’s blog, Science Speaks:

Science Speaks Interviews Key PEPFAR Staff

The Center for Global Health Policy’s blog, Science Speaks, featured interviews this month with key staff members in the Office of the U.S. Global AIDS Coordinator (OGAC), which is responsible for the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) program.

Interviews include:

  • Caroline Ryan, MD, MPH: As director of technical leadership, Dr. Ryan has been a long-time key architect of PEPFAR’s implementation. She spoke about how she became involved and why she has stayed for seven years.
  • Charles B. Holmes, MD, MPH: As chief medical officer and director of research and science, Dr. Holmes is responsible for providing technical and programmatic leadership on issues related to HIV care, treatment, and the prevention of mother-to-child transmission. He discussed his various roles, what steps have been taken so far to end new pediatric HIV infections, and how the HPTN 052 trial results are changing priorities at PEPFAR.
  • Winnie Roberts, PhD: A trained ecologist, Dr. Roberts serves as director of multilateral diplomacy managing OGAC’s engagement with the Global Fund to Fight AIDS, Tuberculosis (TB) and Malaria. Dr. Roberts spoke about what motivated her to join OGAC, how PEPFAR is working with the Global Fund to coordinate services, and what is ahead for both organizations.
  • Bill Coggin: As senior technical officer and co-chair of the interagency TB/HIV technical working group, Coggin works on PEPFAR’s annual TB/HIV guidance and technical considerations for the field. Coggin detailed HIV/TB program funding priorities, and how PEPFAR continues to squeeze the most out of every dollar it spends.

Policy Conference Addresses Lack of New Antibiotics

Leaders from the medical and public health community, government, and the pharmaceutical industry earlier this month convened in Washington, D.C., to discuss the critical need for antibiotic development, current challenges limiting innovation, and what can be done to address this public health crisis.

The Sept. 22 conference, “Reviving the Pipeline of Lifesaving Antibiotics: Exploring Solutions to Spur Innovation,” was organized by IDSA, the Pew Health Group, and the Pharmaceutical Research and Manufacturers of America (PhRMA). (An archived webcast of the day-long conference is available online. An edited version will also be available on the IDSA website in the near future.)

Several IDSA members participated. David Gilbert, MD, FIDSA, chair of IDSA’s Antimicrobial Availability Task Force, described the urgent medical need, including preliminary results from a survey of ID physicians conducted by the Emerging Infections Network. Sixty-two percent of respondents reported seeing at least one infection caused by an organism resistant to all available agents. More than half of these respondents, 55 percent, said that the number of such cases had increased during the past two years.

Helen Boucher, MD, FIDSA, a member of the Antimicrobial Availability Task Force, spoke about the scientific and regulatory challenges hindering antibiotic development and outlined IDSA’s recommendations. (See the Society’s April 2010 policy paper, "Combating Antimicrobial Resistance: Policy Recommendations to Save Lives.”)

A session at the conference also addressed the failure of the marketplace to stimulate new antibiotic development. Panelists discussed how various incentives could stimulate development at different stages (e.g., discovery vs. clinical) by different players, including large and small companies.

The event was an outgrowth of IDSA’s 10 x ’20 initiative, launched in 2010 to spur the development of 10 new systemic antibiotics by 2020 and a sustainable antibiotic research and development enterprise for the long-term.

 

FDA Rolls Out New Foodborne Illness Response Network

A new streamlined system announced by the Food and Drug Administration (FDA) in September is designed to respond more efficiently and rapidly to human and animal foodborne illness outbreaks.

The Coordinated Outbreak Response and Evaluation (CORE) Network will allow for more consistency in monitoring and investigating outbreaks, as well as streamline decision making and improve food safety practices, while building on lessons learned from previous outbreaks, FDA said in a press release.

The CORE Network includes epidemiologists, veterinarians, microbiologists, environmental health specialists, emergency coordinators, and risk communications specialists. Investigators in FDA field offices will complement CORE’s efforts, which will be coordinated with the Centers for Disease Control and Prevention, the U.S. Department of Agriculture, and state public health and agriculture agencies.

CORE will be led by Kathleen F. Gensheimer, MD, MPH, FIDSA, who serves in the new position of chief medical officer/outbreak director. Dr. Gensheimer, a recognized leader in public health, was recently the state epidemiologist for Maine. She has served on numerous IDSA committees, including the Bioemergencies Task Force, Bioterrorism Work Group, National & Global Public Health Committee, Emerging Infections Committee, Public Policy Committee, and the Pandemic Influenza Task Force.

“A real benefit of the network approach is enhancing communication and coordination with federal, state, and local food safety agencies, as well as industry and consumers,” Dr. Gensheimer said in FDA’s press release. “Given my background at the state public health level, this is a major priority for me.”

Input Due Oct. 26 on Changes to Rules Protecting Human Research Subjects

The deadline has been extended for comments on sweeping changes proposed by the Department of Health and Human Services (HHS) in late July to regulations that govern research on human subjects. Comments are now due to HHS by Oct. 26. IDSA plans to submit comments on the proposed changes and encourages IDSA members to do so as well. (See the July/Aug. 2011 IDSA News and an email sent to IDSA members in August for additional resources and how to submit comments to HHS.)

Often referred to as the Common Rule, the regulations have not been substantially revised since they were established in 1991 to guide federally funded research involving human subjects. HHS’ goal is to strengthen protections for subjects while also modernizing and simplifying the current system. Many of the proposed changes address issues IDSA has previously raised concerning the increasing regulatory burden on research (see IDSA’s related policy statement).

For more information, or to share your comments on the proposed changes with IDSA, contact Audrey Jackson, PhD, at IDSA.

IDSA Urges Fix to Flawed Medicare Physician Payment Formula

Of all the changes in Medicare’s 2012 Physician Fee Schedule Proposed Rule, the one posing the most immediate challenge to ID physicians is the steep payment cuts called for by the flawed Medicare physician payment formula. In an Aug. 30 comment letter (PDF), IDSA once again urged the Centers for Medicare and Medicaid Services to work with Congress to fix the Sustainable Growth Rate payment formula, which—if not addressed—will result in a 29.5 percent payment cut for all physicians starting in 2012.

Earlier this month, IDSA, the American Medical Association, every state medical society, and 64 other medical specialty societies called on the special congressional committee tasked with identifying $1.2 trillion in deficit reduction to reform the flawed physician payment formula. The groups’ letter is available online (PDF).

In comments on the CMS proposed rule, IDSA also addressed proposed changes to the Physician Quality Reporting Rule System, the Physician Compare website, and plans to implement a Value-Based Payment Modifier, which will pay physicians differently based on the risk-adjusted cost and quality of their care compared to their peers. In addition, IDSA highlighted problems caused by Medicare’s lack of coverage for home infusion therapy services and the decision not to cover all preventive vaccines under Part B.

In other advocacy news:

  • In a separate letter (PDF), IDSA urged the congressional committee on deficit reduction to use a balanced approach, incorporating both spending reductions and revenue generation, that also protects the nation’s health. The Society recommended against rigid spending caps that force across-the-board cuts that eliminate the opportunity to consider priorities and urged the committee to consider programs protecting public health, biomedical research, and vulnerable populations as targets of last resort when evaluating spending cuts.
  • IDSA and other medical and public health organizations highlighted the scientific evidence illustrating the threat to human health posed by the misuse of antibiotics in animal agriculture in a September letter (PDF) to Congress. The Society and the other organizations called on the Food and Drug Administration and lawmakers to act more boldly and urgently to protect antibiotics vital to human health.
  • IDSA supported the reauthorization of the Pandemic All-Hazard Preparedness Act of 2006 and the Project Bioshield Special Reserve Fund in a letter (PDF) to Sen. Tom Harkin, chairman of the Senate Health, Education, Labor and Pensions Committee. IDSA also addressed the development of antibiotics and related diagnostics, urging that the legislation include an Independent Strategic Investment Firm, improved accountability and coordination of federal antibiotic resistance activities, and the establishment of an Infectious Disease Clinical Specimen Repository.

IDSA Congratulates the 2011 Joint Research Award Winners

The IDSA Education and Research Foundation (ERF) and the National Foundation for Infectious Diseases (NFID) announce the winners of the 2011 IDSA ERF/NFID Joint Research Awards.

Merle A. Sande/Pfizer Fellowship Award in International Infectious Diseases

Katherine A. Plewes, MD, MSc, an infectious disease fellow at the University of British Columbia in Vancouver, Canada, proposes a randomized trial to assess the effect of acetaminophen as an adjunct to artesunate in adults with severe falciparum malaria complicated by blackwater fever. Dr. Plewes hypothesizes that acetaminophen may decrease kidney injury in such patients by inhibiting the hemoglobin-induced lipid peroxidation of free hemoglobin released during massive hemolysis.

Astellas Postdoctoral Fellowship in Transplant Infectious Diseases

Margaret L. Pollack, MD, a fellow in the Division of Allergy and Infectious Diseases at the University of Washington in Seattle, will investigate abortive cytomegalovirus (CMV) transmission from hematopoietic stem cell products to naïve CMV hosts. To further characterize patients with abortive infection and the role of neutralizing antibodies, Dr. Pollack will retrospectively correlate abortive CMV DNAemia and neutralizing antibody titers in a cohort of patients who were transplanted prior to the adoption of pp65 antigenemia/DNA-based pre-emptive treatment strategy and who did not develop replicative CMV infection.

Astellas Young Investigator Awards 

Jeffrey D. Dvorin, MD, PhD, assistant professor in the Division of Pediatric Infectious Diseases at Children’s Hospital Boston and Harvard Medical School, focuses his project on novel therapies that target fundamental life cycle steps of Plasmodium falciparum, the agent that causes most severe cases of human malaria. Dr. Dvorin has identified a plant-like calcium-dependent protein kinase, PfCDPK5, which is crucial for P. falciparum egress. His proposal is to provide a molecular characterization of PfCDPK5 function with advanced genetic and cell biologic techniques. Because the egress life cycle step is not currently targeted by anti-malarials, the identification of the signaling pathway downstream of PfCDPK5 may identify new targets for malaria therapies.

Alexander Ploss, PhD, is an assistant research professor at The Rockefeller University in New York City. His proposal builds on a recent breakthrough from his research group—an engineered mouse that is permissive for hepatitis C virus (HCV) entry. The model, where human HCV entry factors are delivered either transiently or through germ line transgenesis, provides an in vivo model for studying inhibitors of the entry process, including virus-neutralizing antibodies. Dr. Ploss proposes to use state-of-the-art in vivo mutagenesis approaches, coupled with capture of HCV-permissive infected cells, to identify mutations that facilitate HCV replication in the murine cell environment. His goal is to create a fully HCV-permissive mouse model.

ASP-IDSA Young Investigator Award in Geriatrics 

Robin L.P. Jump, MD, PhD, an ID physician at Louis Stokes Cleveland VA Medical Center, aims to reduce the incidence of C. difficile infection among residents of long-term care facilities (LTCF). Her hypothesis is that colonization resistance established by the gut microbiota of older LTCF residents has delayed restoration following antibiotic exposure, rendering this population more vulnerable to C. difficile infection. Her study proposes to incorporate basic science (measuring changes in gut flora) and clinical research (a prospective observational cohort study to determine when patients are no longer vulnerable to C. difficile). This investigation is the first step in determining the specific bacteria taxa and their functions that maintain colonization resistance and developing evidence-based antibiotic stewardship programs to minimize the unintended, adverse effects of antibiotic exposure.

Pfizer Young Investigator Award in Vaccine Development

David K. Hong, MD, an instructor of pediatrics at Stanford University, proposes to better understand the mechanisms by which a novel adjuvant, cationic lipid/DNA complexes (CLDC), induces antigen-specific CD8T cells when injected with protein antigen. Dr. Hong will examine the role of CD8a+ dendritic cells, a specialized dendritic cell involved in cross-presenting antigen to prime naïve CD8 T cells. He will also examine the role of Type 1 interferons (interferon-a/b) in mediating cross-presentation in dendritic cells. Dr. Hong’s long-term goal is to study the role of adjuvants to improve vaccines for respiratory viruses in children. The ultimate goal is to develop improved vaccines that eliminate the need for precisely matched influenza strains every year.

In Memoriam: Richard B. Hornick, MD, FIDSA (1929-2011)

A prominent ID physician scientist, clinician, and teacher, Richard B. Hornick, MD, FIDSA, a former president of IDSA and a founding member of the Society, died Aug. 9, 2011, at the age of 82 in Winter Park, Fla.

During a medical career spanning more than five decades, Dr. Hornick contributed to the treatment and prevention of diseases including tularemia, typhoid fever, dysentery disorders, and others. He was behind some of the groundbreaking studies establishing the typical number of bacteria required to cause typhoid fever and infectious diarrhea, according to a remembrance from the University of Rochester Medical Center in New York, where he was chair of the Department of Medicine from 1979 to 1985.

“One of Dr. Hornick’s greatest strengths was that he recognized the talents of developing physicians and provided them both the emotional and scientific help they needed to jumpstart their careers,” said Robert F. Betts, MD, FIDSA, professor emeritus in the University of Rochester Medical Center’s Department of Medicine, Infectious Diseases, in the university’s remembrance. “He was an extremely nice guy and always welcomed young professionals into the field with open arms.”

Born in Johnstown, Pa., in 1929, Dr. Hornick graduated from Johns Hopkins University in Baltimore in 1951, later earning a medical degree from the university and completing his residency in internal medicine there. Following his service in the U.S. Army at the Walter Reed Medical Unit at Fort Detrick in Maryland, Dr. Hornick joined the faculty of the University of Maryland.

There he rose from assistant instructor to professor of medicine and director of the Division of Infectious Diseases before his appointment in 1979 as professor and chair of medicine at the University of Rochester. In 1987, Dr. Hornick was named vice president for medical education at Orlando Regional Medical Center in Florida. Despite stepping down in 1999, he continued to teach students and treat patients until three weeks before his death from cancer, according to an Orlando Sentinel article.

An active member of many professional organizations and societies, Dr. Hornick was a founding member of IDSA in 1963, a Joseph E. Smadel Lecture winner in 1982, and served as Society president in 1986.

He was also elected to the Institute of Medicine and served as an infectious diseases consultant to the World Health Organization and the Food and Drug Administration. Widely published, he contributed to more than 300 scholarly articles, book chapters, and reports on ID-related topics throughout his career.

Dr. Hornick is survived by his wife, Susan; two sons, Douglas and Thomas; two daughters, Martha Hornick and Blaine Hawley; and seven grandchildren.

New Toolkit Aims to Increase Pneumococcal Immunization in Adults

The National Foundation for Infectious Diseases (NFID) has developed a new toolkit to improve pneumococcal immunization rates among adults to reduce the impact of related illness and death in this population.

The burden of invasive pneumococcal disease in the U.S. lies primarily among adults; 85 percent of all cases occur in people age 18 or older. Vaccination rates are low despite the fact that the Centers for Disease Control and Prevention recommends vaccination for all adults age 65 and older and younger adults who have certain chronic conditions.

To help health care professionals maximize opportunities to vaccinate their patients, NFID has created a new Professional Practice Toolkit. This toolkit includes materials to help educate adult patients about the importance of pneumococcal prevention and assess their risk for pneumococcal disease, and various tools to support providers’ vaccination efforts. The materials are available in English and Spanish, and include information that can be tailored for practices that serve populations affected by disease and immunization disparities (e.g., African Americans, Hispanics, American Indians, Alaska natives).

HIVMA Minority Clinical Fellowship Program: December 9 Application Deadline

The HIV Medicine Association created the Minority Clinical Fellowship Program to increase the number of African American and Latino physicians with the expertise to provide clinical care to patients with HIV in the communities most affected by HIV disease. Two one-year fellowships are awarded annually with one going to an African American physician and one to a Latino physician interested in pursuing careers in HIV medicine in the U.S.  During the year, fellows manage the ongoing care of patients with HIV disease under the supervision of an HIVMA mentor. The award includes a $60,000 stipend plus funding to support benefits for one year.

Applications are being accepted for the 2012 to 2013 fellowship year, which will start on July 1, 2012.  Eligible candidates will be African American or Latino physicians who are within the first five years of their medical practice and have a demonstrated interest in HIV medicine.  Individuals who have completed or have been recently accepted to an infectious diseases training program are not eligible for the program.

The application along with information on current and past fellows is available online at www.hivma.org/Minority_Clinical_Fellowship.aspx. The deadline to apply for the two fellowships that begin in July 2012 is December 9, 2011.

Contact Julio Fonseca at jfonseca@hivma.org with questions or for more information.

From the President: A Year in Review

Although we certainly live in challenging times, the Society’s commitment to work for the good of patients, public health, and our diverse membership remains incredibly strong. Some highlights from the past year illustrate the progress IDSA is making in high priority areas.

As my term as IDSA president nears its end, I want to let you know what a privilege it has been to serve you. Although we certainly live in challenging times, the Society’s commitment to work for the good of patients, public health, and our diverse membership remains incredibly strong. Some highlights from the past year illustrate the progress IDSA is making in high priority areas.

IDSA’s Standards and Practices Guidelines Committee released several important new guidelines for clinicians, including the Society’s first-ever guideline for the treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections and the first national guideline for the management of pneumonia in children, a joint effort with the Pediatric Infectious Diseases Society (PIDS). A growing number of IDSA guidelines are now available in formats for PDAs, iPhones, and iPads, and as pocketcards (see the new IDSA website).

Documenting the value that ID specialists provide to the health care system through improved patient outcomes and reduced health care costs remains an important focus for the Society. IDSA’s Value of ID Specialists Task Force is continuing its work with a health services research firm to assess the value ID clinicians provide to patients and the health system at large.

There is also a special focus on ensuring that the non-patient care activities of ID specialists will be recognized and compensated under the new reimbursement mechanisms envisioned under health care reform. The Clinical Affairs Committee is monitoring the rapidly changing practice environment and promoting the need for equitable reimbursement for the services provided by ID specialists.

Much progress has been made on efforts to address antimicrobial resistance and the antibiotic pipeline crisis:

  • Earlier this month, IDSA, the Pew Health Group, and the Pharmaceutical Research and Manufacturers of America (PhRMA) held a one-day conference with leaders from government, academia, industry, and the medical and public health communities to discuss how to stimulate new antibiotic development (see related article).
      
  • In April, IDSA worked with the World Health Organization (WHO) to publicize World Health Day 2011 which focused on antimicrobial resistance. IDSA held both a press conference at the National Press Club and a congressional briefing in Washington, D.C. The Society also released an important new policy paper outlining recommendations and identifying research priorities to address the crisis (see April 2011 IDSA News).
  • The National Institute of Allergy and Infectious Diseases (NIAID) announced a plan for a new clinical trials network primarily focused on antibiotic-resistant bacterial infections, a step IDSA strongly urged NIAID to take. As NIAID’s planning progresses, IDSA will continue to communicate with you about developments.
  • IDSA continues to strongly advocate for the 10 x ’20 initiative, which calls for the adoption of incentives to spur the development of 10 new systemic antibiotics by 2020 and a multipronged, long-term approach to address resistance and the lack of new antibiotic development. With one drug approved so far, it’s clear that we have a long way to go. IDSA is also working to strengthen and enact new legislation in Congress that contains new incentives targeting the diminishing antibiotic pipeline.

In a time of difficult economic constraints, IDSA has advocated for appropriate federal funding for public health and research at the Centers for Disease Control and Prevention (CDC), the National Institutes of Health, the Food and Drug Administration, and other agencies. The Society has emphasized the long-term value of these investments in preventing needless deaths and reducing health care costs. We will continue to emphasize this message to Congress.

Earlier this month, IDSA and HIVMA launched redesigned websites, part of our commitment to improve communication with members. If you haven’t visited the redesigned sites yet, please do. We welcome your feedback as we continue to work to improve the Society’s online tools (see related article for information to help you navigate the new sites).

Another highlight of this year is the 49th Annual Meeting of IDSA and HIVMA in Boston on October 20-23.This year’s terrific program, developed under the leadership of Barbara D. Alexander, MD, FIDSA, chair of the Annual Meeting Program Committee, features several notable additions: a new global ID programming track; a Friday afternoon symposium focused on “One Health,” an approach that recognizes the connections among people, domestic animals and wildlife, and the environment, and their relevance to infectious disease emergence; and a special Presidential Plenary Session on Sunday morning featuring three lectures on cholera by Stephen J. Calderwood, MD, FIDSA, of Massachusetts General Hospital; J. William Pape, MD, of GHESKIO; and Scott F. Dowell, MD, MPH, of CDC. In addition, I will provide an update on IDSA activities.

Looking ahead, plans are progressing for IDWeek 2012, the first-ever joint meeting of IDSA, the Society for Healthcare Epidemiology of America (SHEA), HIVMA, and PIDS, next fall in San Diego.

Thomas Slama, MD, FIDSA, will assume the role of IDSA president on Oct. 23 in Boston. I am certain his leadership will help the Society build on its accomplishments and serve our diverse and growing membership. He will have much on his plate, as our recent strategic priority setting session indicates (see July/Aug. 2011 IDSA News).  He will benefit, as I have, from the excellent work and dedication of IDSA leaders, committee members, and staff.

It has been an honor to serve you this past year. I look forward to seeing you in Boston.

IDSA, PIDS Release Guidelines for Treating CAP in Children

The first national guidelines for the management of community-acquired pneumonia (CAP) in infants and children are now available.

The first national guidelines for the management of community-acquired pneumonia (CAP) in infants and children are now available. Developed by IDSA and the Pediatric Infectious Diseases Society, the guidelines are online and appear in the Oct. 1 issue of Clinical Infectious Diseases.

The guidelines are designed to provide physicians who care for children with a roadmap to the most scientifically valid diagnosis and treatment recommendations. They also place an emphasis on preventing bacterial pneumonia through immunization, including annual influenza vaccination for children 6 months and older, and for parents and caregivers of infants 6 months and younger.

Topics in the guidelines include:

  • site-of-care management decisions
  • diagnostic testing
  • anti-infective treatment
  • adjunctive surgical and non-anti-infective therapy
  • management of children not responding to treatment
  • discharge criteria
  • prevention

“Diagnostic methods and treatments that work well in adults may be too risky and not have the desired result in children,” said John S. Bradley, MD, FIDSA, lead author of the guidelines and professor and chief of the division of infectious diseases at the University of California at San Diego Department of Pediatrics. “With these guidelines, we are hopeful that the standard and quality of care children receive for community-acquired pneumonia will be consistent from doctor to doctor—providing much better treatment outcomes.”

For each of the guidelines’ specific recommendations, the strength of each as well as the quality of evidence for each is noted. The document also notes the lack of solid evidence in some areas, often due to the ethical challenges of studying children, and calls for research in specific areas.

The guidelines have been endorsed by the American Academy of Pediatrics, the American College of Emergency Physicians, the American Society of Microbiology, the American Thoracic Society, the Society for Hospital Medicine, and the Society of Critical Care Medicine.

The CAP guidelines are available online and are also being developed in both mobile device and pocketcard format for use at the point of care. Other IDSA guidelines are also available on the IDSA website, including guidelines available in these formats.

IDSA Journal Club

September 2011

This month, studies investigating: outcomes of C. difficile-associated diarrhea in patients using concomitant antibiotics; a possible new broad-spectrum antiviral; daily azithromycin for the prevention of chronic obstructive pulmonary disease exacerbations; and exposure to varicella zoster virus and risk of herpes zoster.

In this feature, a panel of IDSA members identifies and critiques important new studies in the current literature that have a significant impact on the practice of infectious diseases medicine.

Click here for the previous edition of Journal Club. For a review of other recent research in the infectious diseases literature, see “In the Literature,” by Stanley Deresinski, MD, in each issue of Clinical Infectious Diseases.


Outcomes of C. difficile-Associated Diarrhea in Patients using Concomitant Antibiotics
Reviewed by Khalil Ghanem, MD, PhD

A secondary analysis from two trials demonstrated that concomitant antibiotic use during or shortly after Clostridium difficile-associated diarrhea (CDAD) treatment resulted in lower cure rates and longer duration of symptoms, and suggested that participants treated with fidaxomicin had fewer recurrences than those treated with vancomycin. The findings are published in the Sept. 1 issue of Clinical Infectious Diseases.

Thirty percent (N=275) of participants enrolled in the two randomized controlled trials (N=999), which compared efficacy of 10 days of oral fidaxomicin (200 mg orally twice daily) with oral vancomycin (125 mg orally four times daily) in the treatment of CDAD, received concomitant antibiotics (CA). Patients were assessed and compared to participants who did not receive CA. The investigators’ goal was to describe the impact of CA use during or shortly after CDAD therapy and compare cure rates in participants receiving oral vancomycin vs. fidaxomicin. Participants were followed up for 40 days after CDAD treatment completion.

Overall, clinical cure was achieved in 93 percent of participants who did not receive CA vs. 84 percent of those who did. Median time to resolution of diarrhea was longer in participants who received CA (97 hours vs. 54 hours). There was a statistical trend for increased probability of recurrence among patients who received CA (23 percent vs. 17.6 percent). Among participants who received CA, the cure rate for fidaxomicin was 90 percent vs. 79.4 percent for vancomicin. 

This study provides clinicians with useful estimates of recurrence risk, cure rates, and duration of symptoms in CDAD, particularly among persons who use CA during CDAD therapy, a not uncommon occurrence among hospitalized patients. Clinicians must weigh costs and benefits when deciding to use fidaxomicin over vancomycin. The question of extending the duration of CDAD therapy in participants who were receiving CA was not addressed in the study.

Promising Early Look at a Possible Broad-Spectrum Antiviral
Reviewed by Jason Weinberg, MD

A novel class of compounds that induces cell death only in virus-infected cells may one day serve as a broad-spectrum antiviral strategy, according to an article published online on July 27 in PLoS One.

To specifically target cells that are infected by a virus, the investigators took advantage of a naturally occurring intracellular immune process that recognizes double-stranded RNA, a product produced in virus-infected cells during the course of virus replication.  The investigators synthesized compounds that coupled domains that recognize double-stranded RNA to domains capable of triggering apoptotic cell death. The compounds were nontoxic and effective in a variety of cell types.

 In a series of in vitro experiments, the compounds induced the death of virus-infected cells, thereby limiting ongoing viral replication and preserving the viability of uninfected cells. This strategy was successful when cells were infected with rhinovirus, influenza, and several other RNA and DNA viruses. No obvious toxicities were documented when mice were treated with the compounds, and treatment of mice infected with H1N1 influenza decreased viral replication and increased survival.

Established and emerging viruses continue to cause substantial disease. There have been important successes with vaccines to prevent virus infection and associated disease, but the repertoire of effective antiviral drugs is still very small. The successes with the novel antiviral strategy described in this report were confined to the laboratory, but the strategy is very appealing. The compounds used by the investigators are very specific, because double-stranded RNA is produced only in virus-infected cells. They are also broad-spectrum, because double-stranded RNA is produced during the replication of both RNA and DNA viruses. It will be exciting to see if compounds such as these move beyond the proof-of-concept stage and into clinical trials to provide a much-needed new class of antiviral therapeutics.

Daily Azithromycin for the Prevention of COPD Exacerbations
Reviewed by Kathryn E. Stephenson

Exacerbations of chronic obstructive pulmonary disease (COPD) result in recurrent courses of antibiotics, steroids, and hospitalizations, and are associated with an increased risk of death. In the Aug. 25 issue of the New England Journal of Medicine, investigators tested whether daily azithromycin, when added to the usual care of patients, would decrease the frequency of these exacerbations compared to a placebo.

In a large, multi-center clinical trial, 1,142 patients were randomized to receive azithromycin at 250 mg by mouth daily or an identical placebo for one year. The primary outcome of the study was the time to the first acute exacerbation of COPD, defined as the increase or new onset of cough, sputum, or respiratory difficulty with the initiation of antibiotics or steroids. The authors also investigated changes in quality of life, nasopharyngeal bacterial colonization, and hearing.

An intention-to-treat analysis showed that the risk of acute exacerbations of COPD was reduced among subjects receiving azithromycin (P<0.001), and that the median time to the first exacerbation was 266 days in the azithromycin arm compared to 174 days in the placebo arm (P<0.001). These differences were significant even when controlled for demographics, behaviors, and pulmonary function. The authors calculated that the number needed to treat to prevent one acute exacerbation of COPD was 2.86.

Though there were no significant differences in the frequency of serious adverse events, the authors did report that subjects treated with azithromycin had more pronounced hearing decrements than those who received placebo. In addition, subjects who became colonized with respiratory pathogens during the study were more likely to have macrolide-resistant organisms if they had received azithromycin as opposed to placebo.

In sum, this large, randomized clinical trial demonstrates that azithromycin can be a valuable tool when treating patients suffering from recurrent COPD exacerbations.

Absence of Exposure to Varicella Zoster Virus and Risk of Herpes Zoster
Reviewed by George R. Thompson III, MD

Control of varicella zoster virus  (VZV) reactivation and the avoidance of herpes zoster is largely dependent upon effective cell-mediated immunity. However, the relationship between the epidemiology of varicella and zoster remains unclear. Two primary hypotheses have been proposed:  (1) exogenous boosting from exposure to children with varicella, and (2) endogenous boosting from subclinical reactivation of latent VZV within the sensory ganglia. A study published in the Sept. 1 issue of Clinical Infectious Diseases offers some interesting findings on this issue.

Researchers conducted a national, multicenter, observational, comparative study of exposed versus nonexposed subjects. The nonexposed group consisted of members of Roman Catholic monastic orders (monks and nuns), an isolated population in France with little exposure to children. Those who were members for <2 years or had previous zoster were excluded. The exposed group was comprised of members of the general population and matched to members of the monastic order group.

The frequency of zoster in the monastic order group (16.2 percent) did not significantly differ from the frequency in the general population group (15.1 percent) (P=0.27). Additionally, the age of onset was 54.8 years in the monastic order group and 48.6 years in the general population (P=0.06).

The authors’ results are intriguing and challenge prior assumptions that the absence of contact with varicella causes an increased risk of zoster. Additionally, their findings support the assertion that childhood vaccine programs against VZV will not lead to an increasing number of cases of zoster in young adults.

(Gaillat et al. Clin Infect Dis. 2011;53(5):405-410.)
