CDC Recommends Influenza Vaccine for
Federal officials are urging influenza vaccination for all health care workers (HCWs) as part of a strategy to boost immunization rates for influenza.
Estimated coverage rates are less than 50 percent among critical groups for whom annual influenza vaccination is recommended, including HCWs, young children, adults with risk factors for influenza complications, and pregnant women.
A new report from the Centers for Disease Control and Prevention (CDC) recommends implementing or expanding strategies such as reminder/recall systems and standing orders programs. Among other considerations, CDC states that health care facilities should consider the level of vaccination coverage among HCWs to be one measure of patient safety and quality. In a move previously supported by IDSA, CDC suggests obtaining signed statements from HCWs who decline influenza vaccination.
The report makes no changes concerning the groups for whom vaccination is recommended or the antiviral medications used for chemoprophylaxis or treatment (oseltamivir or zanamivir).

Key Studies Proposed to Answer Basic Questions
What is the optimal duration of therapy for cellulitis? Are two drugs better than one for community acquired pneumonia (CAP)? Are antibiotics really necessary when treating otitis media?
The evidence supporting the standard of care for these and other common infections is surprisingly weak. Inappropriate use of antibiotics is a major factor driving the growing epidemic of antibiotic-resistant infections. With a movement on the rise to penalize institutions for health care-associated infections, infectious diseases experts are looking for solid answers.
“Despite using antibiotics for decades, we still don’t know how to use them optimally,” said Louis B. Rice, MD, chair of IDSA’s Research on Resistance Work Group. For years, IDSA has been urging the National Institute of Allergy and Infectious Diseases (NIAID) to study these issues. This summer, the Society proposed three multi-center, controlled clinical trials using generic antibiotics to answer key questions about cellulitis, CAP, and otitis media in children, and to lay the groundwork to answer more.
Three days vs. seven to 10 days of antibiotic therapy for uncomplicated, community acquired cellulitis. The optimal duration of therapy for cellulitis, an extremely common infection for which large quantities of broad-spectrum antibiotics are prescribed, has not been defined. Shorter courses may work just as well as longer courses, while reducing exposure to antibiotics and the growth of resistant bacteria.
A three-armed study of community acquired pneumonia comparing seven days of aß-lactam, seven days ofß-lactam plus azithromycin, and three days ofß-lactam alone. Current guidelines recommend an agent against atypical pathogens, but there is evidence suggesting this does not improve outcomes. Also, some studies suggest shorter therapy with a ß-lactam may be just as effective as the current seven-day standard. Definitive answers are needed.
Amoxicillin or azithromycin plus analgesics vs. placebo plus analgesics for children older than 6 months with middle ear infections. More prescriptions for antibiotics are written for children with acute otitis media than anything else, but the evidence that antibiotics improve the time to resolution of symptoms is weak.
These issues have gone unresolved for so long because antibiotics have long been considered relatively benign medications with little risk to the patient, Dr. Rice said. The prevailing wisdom has been that the risk to the patient of an infection recurring is greater than the risk of taking more antibiotics than necessary. “But now we have MRSA, we have resistant Klebsiella and Pseudomonas, we have Acinetobacter, and we have C. difficile,” Dr. Rice said. “We have to weigh the risks and benefits differently.”
IDSA drew up this proposal at the request of NIAID and has been in close communication with the institute. IDSA’S ultimate aim is to persuade NIAID develop the infrastructure to carry out more trials on antimicrobial usage.
This summer, NIAID has awarded two contracts to address the cellulitis question. These multisite, phase II/III clinical trials will use generic antibiotics to find optimal ways to treat uncomplicated skin and soft tissue infections caused by community acquired MRSA. The goal is to preserve the efficacy of vancomycin, linezolid, and other final-option drugs.

Help Win Medicare Coverage for Antimicrobial
A bill in Congress would guarantee Medicare beneficiaries’ access to home infusion of antibiotics and other drugs by requiring Medicare to cover the related services. The bill, the Medicare Home Infusion Therapy Coverage Act of 2007 (H.R. 2567), introduced by Rep. Eliot Engel (D-NY), supports one of IDSA’s long-standing legislative priorities.
In 2003, Congress passed the Medicare Modernization Act (MMA), which directed the Centers for Medicare and Medicaid Services (CMS) to cover home infusion drugs under the new prescription drug benefit. Unfortunately, the legislation did not require CMS to cover the services related to the provision of infusions at home, including pharmacy services, physician services, supplies, and equipment. This decision means that most Medicare beneficiaries still do not have access to infusion drugs, including antimicrobials, in the home setting.
IDSA needs your help to educate Congress about why home infusion services should be covered. Please visit IDSA’s online home infusions therapy resources at http://www.idsociety.org/homeinfusions.htm for more information about H.R. 2567 and to contact your members of Congress.
Also, if you treat Medicare patients who would like to share their experiences of how Medicare’s lack of coverage for home infusion therapy services has limited their treatment options and otherwise disadvantaged them, please have them contact Jason Scull of IDSA’s Clinical Affairs staff at firstname.lastname@example.org or (703) 299-5146.
IDSA On Your Behalf
IDSA works on the state and federal levels to ensure that public health policies are based on a sound scientific foundation. Here is a sample of IDSA’s recent policy activities:
- IDSA Endorses Access to Medicare Data Act 07/16/07
The bill would advance medical research into antimicrobial resistance and other areas by providing federal health officials and other health researchers with controlled access to data on physician and prescription drug claims processed on behalf of Medicare beneficiaries.
- IDSA, Others Oppose Thimerosal Amendment 07/18/07
IDSA joined several organizations opposing an amendment that would prohibit the use of federal funds to administer an influenza vaccine containing the preservative thimerosal to children less than 3 years of age. Science has not found thimerosal to be detrimental.
- IDSA Urges Changes for Rhode Island Lyme Disease Bill 06/19/2007
IDSA urged the Rhode Island State Senate to amend a bill that establishes a special commission to study Lyme disease, so that the commission would include board-certified ID physicians who represent a more balanced perspective. The Society also has weighed in on bills in Massachusetts and Pennsylvania.

Physicians Could See 10 Percent Pay Cut
In what has become an annual ritual, physicians once again are facing a cut in Medicare reimbursement, but Congress once again is expected to block it and pass a small increase instead.
This year’s proposed cut is nearly 10 percent, according to the formula known as the sustainable growth rate (SGR). While physician payments were cut in 2002, Congress has intervened to prevent the cuts for the past five years. Congress has not yet dealt with the fundamental flaws in the SGR, however. The Congressional Budget Office estimates that replacing the SGR with a formula that allows payment rates to increase by the rate of medical inflation would cost $218 billion over 10 years.
Congress is considering changes to the SGR as part of a multi-pronged bill, known as the Children's Health and Medicare Protection (CHAMP) Act. The CHAMP Act includes a .5 percent increase in Medicare physician payments, and also breaks the SGR up into six separate formulas that group similar physician services together. These changes would cost significantly less than a full scale repeal of the SGR.
IDSA supports the bill, with a few reservations. IDSA’s letter to key Congress members on the issue is online, and go to IDSA’s Advocacy Center to urge your legislators to support the CHAMP Act.a

In Memoriam: Ward Bullock, Jr., MD
by Peter D. Walzer, MD, MSc, and George Deepe, MD
It is with the deepest sorrow that we announce the death of Ward E. Bullock, Jr., MD, emeritus professor of medicine and former director of the division of infectious diseases at the University of Cincinnati College of Medicine. Dr. Bullock passed away on April 17 at the age of 75.
Ward received his MD degree from Temple University. He performed his internal medicine residency at the University of Minnesota and completed his training in infectious diseases and immunology at Yale University. He first came to prominence in the 1960s for his studies of leprosy performed at the U.S. Naval Medical Research Unit in Taiwan. A groundbreaking article in the New England Journal of Medicine revealed the impairments of cellular immunity associated with leprosy. This paper and others reawakened international interest in leprosy research.
Ward continued his productive leprosy work at the University of Cincinnati, where he served as associate chair for research in internal medicine and senior associate dean, and also turned his attention to Histoplasma capsulatum. Using his experience with leprosy, he pioneered the study of the host response to this fungus in both animal models and humans. Ward’s steady output of insightful publications on the immunopathogenesis of histoplasmosis had a major national impact on stimulating interest in medical mycology.
Ward’s academic accomplishments were recognized in many ways: consistent NIH funding, membership in prestigious societies, and service on advisory panels and editorial boards. The characteristics we appreciated most were his vision, leadership, concern for the common good, and tireless support of the efforts of his faculty and fellows to achieve excellence in their activities.
Ward Bullock touched the lives of many people. He will be sorely missed. Ward is survived by his wife, a son and daughter, a brother, a sister, three step-daughters, and seven grandchildren.

Avian Influenza Virus Infection in Veterinarians
In this case-control study, the health of patients with botulism was evaluated >6 months after illness. Those who had previously had botulism were substantially more likely than control subjects to report fatigue, generalized weakness, dizziness, dry mouth, difficulty lifting things, and difficulty breathing with moderate exertion.(Myers et al., Clin Infect Dis. 2007;45:4-9.)
Ionization, Fungi, and Health Care Water Supplies
In a study ofthe hot and coldpotable water supplies ofSpanish health care centers,the prevalence of fungiwas significantly lower insystems using copper- orsilver-ionized water than insystems using nonionized water. (Pedro-Botet et al.,Clin Infect Dis. 2007;45:84-86.)
Long-term Outcomes of Botulism
In this case-control study,the health of patientswith botulism was evaluated>6 months after illness.Those who had previouslyhad botulism were substantiallymore likely than controlsubjects to report fatigue,generalized weakness, dizziness, drymouth, difficulty lifting things,and difficulty breathing withmoderate exertion. (Gottlieb et al., Clin Infect Dis. 2007;45:174-180.)
Genetic Factors Linked to Fever Following Smallpox Vaccination
New evidence supports the link between genetic factors and certain adverse events related to smallpox vaccination. The study may have implications for predicting adverse events from other live vaccines. Researchers studied 346 individuals who had participated in previous smallpox vaccination trials, 94 of whom developed fevers after vaccination. The authors identified a total of eight haplotypes in four different genes that were associated with altered susceptibility to fever after vaccination. (Stanley et al., J Infect Dis.2007;196:212-219.)
New Data on Transmission, Malignancy of Human Herpesvirus 8 (HHV-8)
In a study examining 13,894 adults in the National Health andNutrition Examination Survey III, researchers found transmission of HHV-8 (also known as Kaposi sarcoma-associated herpesvirus) in men linked to sexual activity, especially male-to-male sexual activity, but not linked to heterosexual transmission to women. (Engles et al., J Infect Dis. 2007;196:199-207.) A second study found HHV-8 was not a major cause of prostate cancer, disputing the conclusions of a previous study that had found elevated levels of HHV-8 antibodies in men with prostate cancer. (Jenkins et al., J Infect Dis 2007;196:208-211.)
Altered Gene Expression in Postinfective Fatigue Syndrome (PIFS)
In a unique, prospective, population-based study that may open doors to better understanding of chronic fatigue syndrome, the authors examined changes in gene expression in patients who developed PIFS following Epstein-Barr virus infection. They identified 35 gene expression changes that correlated with the course of PIFS. These genes had not previously been linked to PIFS and included genes involved insignal transduction pathways, metalion binding, and ionchannel activity. (Cameron et al., J Infect Dis.2007;196:56-66.)
ACIP Issues New Immunization Recommendations
Samuel Katz, MD, IDSA liaison to ACIP
The Advisory Committee on Immunization Practices (ACIP), which advises the Centers for Disease Control and Prevention, made the following recommendations at its June meeting:
Meningococcal Conjugate Vaccine for Teens: Meningococcal conjugate vaccine (MCV4) is back in abundant supply, so vaccination of 11-12 year olds has been resumed. ACIP now recommends giving the vaccine to all persons aged 11-18 years. So far, 7.5 million doses have been distributed. An estimated 1,400 to 2,800 cases of meningococcal disease occur in the U.S. annually, with high rates of morbidity and mortality.
Hepatitis A Vaccine for Post-Exposure Prophylaxis: A change in the recommendation for post-exposure prophylaxis for hepatitis A virus (HAV) calls for use of HAV vaccine up to 14 days after exposure, rather than immune globulin (IG), for healthy individuals 1 to 40 years of age. For others IG is still preferred, including infants under 12 months of age, adults over age 40, immunocompromised individuals, and those with chronic liver disease.
Adult Immunization Schedule: A new adult immunization schedule for 2007-2008 reflects current recommendations for use of licensed vaccines in people 19 and older. Changes include the addition of zoster vaccine.
Slide presentations and the full ACIP report will be available at www.cdc.gov/vaccines/recs/acip/default.htm.
West Nile Virus Epidemic Continues
A 14 percent increase in reported cases of West Nile Virus neuroinvasive disease (WNND) last year suggests that the West Nile Virus (WNV) epidemic is here to stay. The number of WNND cases reported to the Centers for Disease Control and Prevention (CDC) rose to 1,491 last year – the highest number reported since 2003. The west-central states and Idaho hosted the majority of human WNV disease cases and Washington reported its first human cases. This increase in WNV activity across the United States emphasizes the need for continued surveillance, research, and mosquito control. Click here for the CDC’s 2006 West Nile Virus activity report.
Malaria Rates Increase in 2005
The Centers for Disease Control and Prevention (CDC) saw an increase of about 15 percent in reported malaria cases in 2005. Most of the increase resulted from cases from the Americas and Asia. It is unclear, however, whether this is due to better reporting or an increase in travel to these areas. Among travelers, those returning from West Africa had the highest case rates.
Only 18 percent of those who acquired malaria while traveling had followed a CDC-recommended chemoprophylaxis regimen. See http://www.cdc.gov/travel.

New JID Supplement Tackles HIV-TB Co-infection
The latest on key issues in the diagnosis and treatment of tuberculosis (TB) in HIV-infected patients is presented in a supplement to the August 1 issue of The Journal of Infectious Diseases.
The supplement includes up-to-date articles by leaders in many areas of this complex dual pandemic. Topics include:
Treatment strategies for HIV-TB co-infection
Drug interactions, additive toxicities, and immune reconstruction syndrome
Research on new drugs, new diagnostics
TB prevention in the context of HIV infection
Models for integrating TB and HIV programs
The supplement grew out of two major meetings in the summer of 2005 on the current state of the science in HIV-TB co-infection—one in Boston, Massachusetts, and one in Rio de Janeiro, Brazil. Following those two meetings, authors were asked to summarize current knowledge and areas of needed research in the areas of diagnostics and therapeutics.
The focus of the supplement is on treatment in resource-constrained settings, particularly sub-Saharan Africa. The authors expect there will be other supplements summarizing key issues in different geographic regions and highlighting different aspects of both pandemics, such as vaccine development or the impact of injection drug use.
