Nosocomial bloodstream infections in HIV-infected patients: attributable mortality and extension of hospital stay.
A 3-year prospective matched case-control study was performed to investigate the potential risk factors, prognostic indicators, extension of hospital stay, and attributable mortality of nosocomial bloodstream infections in HIV-infected patients. Matching variables were: age, gender, number of circulating CD4+ T lymphocytes, cause of hospital admission, hospitalization in the same ward within the 6 weeks of diagnosis of the case, and length of stay before the day of infection in the case. Eighty-four cases and 168 matched controls were studied. ⋯ Nosocomial bloodstream infections are more common in patients with advanced HIV disease. Important cofactors are high APACHE II score and use of CVC. These infections can cause an excess mortality and significantly prolong the hospital stay of HIV-infected patients.

A prospective study of community-acquired bloodstream infections among febrile adults admitted to Mulago Hospital in Kampala, Uganda.
Septicemia is a frequent cause of death in HIV-infected adults in developing countries. Additional prospective studies are needed to determine the etiology of bloodstream infections (BSI) in febrile HIV-infected adults and guide initial evaluation and treatment in this setting. We assessed the prevalence and etiology of community-acquired BSI among 299 consecutive febrile adult medical admissions to Mulago Hospital, Kampala, Uganda, over a 4-month period in 1997. ⋯ Bacteremia and disseminated tuberculosis are frequent causes of morbidity in febrile HIV-infected Ugandan adults. Initial empiric antibiotic coverage in this setting should be targeted toward the pneumococcus and gram-negative enteric bacilli, especially nontyphi Salmonella species. All patients presenting with chronic cough should be evaluated for tuberculosis.

Randomized Controlled Trial Clinical TrialMexiletine for HIV-infected patients with painful peripheral neuropathy: a double-blind, placebo-controlled, crossover treatment trial.
Although mexiletine, an antiarrhythmic with local anesthetic properties, has been reported to relieve discomfort in diabetic neuropathy, its usefulness in the treatment of HIV-related painful peripheral neuropathy (PPN) has not been determined. The tolerance and effectiveness of mexiletine in HIV-related PPN were assessed in 22 patients who were randomized to receive mexiletine (maximum dose, 600 mg/day) or placebo for 6 weeks, followed by the alternative intervention for 6 weeks after a 1-week washout period. The daily pain response was assessed using a visual analogue scale card in 19 patients who received at least 2 weeks of the drug, 16 of whom were crossed-over to receive the alternate agent. ⋯ Dose-limiting adverse events occurred in 39% of those receiving mexiletine, but only 1 patient (5%) discontinued placebo. Mexiletine was only modestly well tolerated despite its relatively brief period of administration, and no evidence was found to support its benefit in HIV-related PPN. Although a first-drug effect was not demonstrated, a powerful placebo effect was seen in some patients.

Provider attitudes regarding participation of women and persons of color in AIDS clinical trials.
Provider attitudes and perceptions that may influence recruitment and enrollment of diverse patients into AIDS clinical trials were examined by conducting a cross-sectional survey of all HIV/AIDS providers at a municipal teaching hospital. Providers were less likely to feel confident explaining trials to non-English-speaking patients (p < .05). Providers also reported being more confident of their ability to give an overview of clinical trials in culturally appropriate terms to white patients than to patients of other races/ethnicities (p < .05). ⋯ Despite these perceptions, all providers reported that they are just as likely to inform women and African Americans about available clinical trials; a small proportion reported that they were less likely to inform Latinos (6%) and Haitians (11%). None of these findings differed significantly by provider race, gender, HIV experience, languages spoken, or specialty. Underrepresentation of minorities and women in AIDS Clinical Trials may partially result from attitudes and perceptions of providers.

Determinants of progression of HIV infection in a Greek hemophilia cohort followed for up to 16 years after seroconversion.
Our objectives are to describe the progression of HIV disease and to assess the influence of hemophilia-related variables, age at infection, and antibodies to cytomegalovirus infection (anti-CMV) in a Greek cohort of 158 HIV-1-positive hemophilic men, who received prospective follow-up for up to 16 years after infection. A total of 79 patients had died, representing a cumulative progression rate of 72.4% (95% confidence interval [CI], 56.6-83.3). A significant proportion of the mortality (30%) resulted from conditions not formally related to AIDS, with liver failure and cerebral hemorrhage predominant. ⋯ Appropriate modeling showed a nonlinear age effect, with a steeper increase of relative hazard for patients >40 years of age at seroconversion. The age effect remained significant even after controlling for current CD4 cell count. Further investigation is required to elucidate the mechanisms of the age effect and the contribution of HCV coinfection on the disease progression.
