In many patients, the etiology of community-acquired pneumonia is not known but may be caused by previously undescribed pathogens in some cases. The recently identified hantavirus Sin Nombre (SN) causes hantavirus pulmonary syndrome. Because sporadic cases have occurred outside the range of its reservoir (the deer mouse Peromyscus maniculatus), an investigation sought to determine whether hantaviruses contributed to cases of community-acquired pneumonia in a large Baltimore hospital. Acute-phase sera from 385 hospitalized patients with pneumonia were examined using an IgG ELISA technique with antigens prepared from several hantaviruses: prototype Hantaan (HTN), Seoul (SEO), Puumala (PUU), Convict Creek (HN107), and SN. Of 385 sera, 8 (2.1%) showed some reactivity with one or more HTN, SEO, or PUU antigens but none had detectable specific IgM antibodies. No sera were reactive with SN or HN107 antigens. Thus, hantaviruses are an uncommon cause of community-acquired pneumonia in the Baltimore area. [ABSTRACT FROM AUTHOR]

We describe a 39-year-old woman who had undergone bilateral lung and renal transplantation and who was admitted to the hospital with acute onset of flaccid paralysis of the left leg due to echovirus 19 infection. The patient was treated with pleconaril and intravenous immunoglobulin, which correlated with clinical and laboratory evidence of improvement.

Patients who are colonized with enteric vancomycin-resistant Enterococcus faecium (VREF) are a major reservoir for transmission of and infection with this organism. In a randomized, controlled study to assess the effectiveness of high-dose bacitracin in the eradication of enteric VREF, 12 patients who were colonized with VREF were randomized to receive placebo (n=6) or orally administered zinc bacitracin (n=6) for 10 days. Posttreatment perirectal or stool cultures indicated that after 3 weeks, VREF had been eradicated from the stool of only 2 (33%) of 6 patients in each group. Of the 8 remaining patients who were still VREF-positive at 3 weeks after treatment, 5 (62%) had later evidence of spontaneous enteric eradication at 8 weeks. Further testing of VREF isolates revealed that a significant number (n=22, 76%) were resistant to bacitracin and that patients may have been colonized with multiple different VREF strains. Although bacitracin was not effective in the enteric eradication of VREF, the high rates of spontaneous eradication suggest that other host and environmental factors are more important in achieving long-term suppression or elimination of VREF colonization.

The availability of potent antiretroviral medications has raised new concerns regarding continued HIV transmission risk behavior among seropositive persons. Relatively little is known about how women with HIV perceive secondary transmission risk in the context of HIV treatment advances. This study describes sexual risk perceptions and behaviors of 80 women enrolled in HIV outpatient care in 1999. Participants completed structured interviews assessing sexual risk perceptions, attitudes regarding severity of HIV disease, sources of HIV prevention information, and sexual practices during the previous 6 months. Medical histories including 6-month cumulative incidence of sexually transmitted diseases (STDs) were obtained from a clinic database. Thirty-five percent of the sample had engaged in unprotected intercourse or had been diagnosed with an STD in the past 6 months. Only 5% of women believed that medication-related reductions in viral load signify safer sex is unimportant, but 15% indicated they practice safer sex less often since the advent of new HIV treatments and 40% believed AIDS is now a less serious threat. These data suggest women's perceptions of diminished disease severity may be more influential than beliefs regarding diminished infectivity. Study results have implications for framing prevention messages for women and suggest that close integration of secondary prevention and clinical HIV services may be beneficial.

The authors surveyed 202 patients (54.5% male; 62.4% African American) enrolled at St. Louis HIV clinics to identify the importance of various sources of influence in their HIV medication decisions. Physicians were the most important source for 122 (60.4%) respondents, whereas prayer was most important for 24 respondents (11.9%). In multivariate tests controlling for CD4 counts, Caucasian men were more likely than Caucasian women and African Americans of both genders to select a physician as the most important source. African Americans were more likely than Caucasians to mention prayer as the most important source. Caucasians and those rating physicians as the most important source were more likely to be using antiretroviral medications. Respondents identified multiple important influences-hence the potential for conflicting messages about HIV medications. These findings have implications for health education practices and behavioral research in the medical setting.

The demographic, behavior, and background characteristics of 4,804 participants in 17 national demonstration projects for HIV medical and/or psychosocial support services were coded for an index of "service need" or possible under-representation in the traditional healthcare system. Fifteen items were coded including status as a person of color, lack of private insurance, unemployment/disability, problem drinking, crack cocaine use, heroin use, other illicit drug use, less than 12 years of education, criminal justice system involvement, children requiring care while the patient receives services, sex work, being the sex partner of an injection drug user, unstable housing, primary language not English, and age less than 21 or over 55 years. Most (87.7%) of the program participants had four or more of these factors present. Through CHAID modeling, those groups with the highest levels of service need and vulnerability were identified. These data suggest that these projects, designed to attract and serve individuals potentially underrepresented in the health services system, had in fact achieved that goal. Implications of the changing demographics of the HIV epidemic for the health service delivery system are discussed.

In a recent survey of women with HIV, prayer was mentioned as a very important source in decision making about HIV antiretroviral therapy. As a follow-up to this finding, we conducted in-depth interviews with 51 women attending a comprehensive HIV care center to better understand the role of prayer in their decisions about taking antiretroviral therapy. The sample consisted predominately of African American (80%) women with a median age of 31 years from St. Louis and surrounding areas. Forty-seven (92%) reported that prayer was an important source for HIV medication decision making, with 30 (59%) considering prayer more important than the physician. Twenty-nine (57%) perceived a qualitative difference between prayer and the physician, which created a sense of conflict for some. Thirty (59%) wished that the physician knew more about the role of prayer in their lives. Our findings reveal compelling issues: (a) the willingness of the women to talk about prayer as a resource and its importance in HIV disease management, (b) the roles that prayer and the physician play in HIV medication decision-making, and (c) ways prayer can be addressed in a medical setting.
