Sex differences in nevirapine rash.

Nevirapine is a nonnucleoside reverse transcriptase inhibitor (NNRTI) that has the most common treatment limiting side effect of rash. Severe rash has been observed in 3% of patients taking nevirapine in clinical trials, 85% of whom were men. In a multicenter, retrospective cohort study of all patients who received nevirapine over a 5-year period, severe rash was noted in 9 of 95 women and 3 of 263 men (risk ratio [RR], 8.31; 95% confidence interval [CI], 2.3-30.0; P=.005). Women were more likely to discontinue nevirapine therapy because of rash (RR, 4.5; 95% CI, 1. 9-10.5; P=.0005). After adjusting for age and baseline CD4 cell count in multivariate analysis, women had a 7-fold increase in risk for severe rash and were 3.5 times more likely to discontinue nevirapine therapy. In women of reproductive age for whom contraception may occur, nevirapine remains the NNRTI of choice. Recognition of sex differences in this severe adverse event will be important in prescribing nevirapine.

Sexually transmitted disease acquisition among women infected with human immunodeficiency virus type 1.

Recent evidence suggests that sexually transmitted diseases (STDs) enhance the transmission of human immunodeficiency virus (HIV) type 1. In 143 HIV-infected women enrolled in a university-based longitudinal HIV clinic over 16 months (mean), the STD point prevalence was examined at enrollment and the cumulative prevalence was calculated at follow-up. At enrollment, 35 women (25%) had > or = 1 STD. These included trichomoniasis in 16 women (11%); syphilis, 9 (6%); genital herpes, 8 (6%); gonorrhea, 5 (4%); chlamydia, 5 (4%); genital warts, 2 (1%); and pelvic inflammatory disease (PID), 1 (1%). STDs were found in 55 (42%) of the 125 patients who returned for at least one follow-up visit: trichomoniasis in 23 (18%); genital herpes, 20 (12%); gonorrhea, 9 (7%); syphilis, 7 (6%); genital warts, 7 (6%); chlamydia, 5 (4%); and PID, 4 (3%). Despite counseling at both enrollment and follow-up, these women had a very high cumulative prevalence of STDs, indicating persistent high-risk sexual behavior.

Primary pulmonary botryomycosis: case report and review.

Botryomycosis is an uncommon bacterial disease characterized by the microscopic formation of eosinophilic granules that resemble those of infection by Actinomyces species. The diagnosis of botryomycosis can be made when microscopic inspection and culture of the granules reveal gram-positive cocci or gram-negative bacilli. Botryomycosis is caused by common bacterial pathogens including Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, yet the host and microbial factors that contribute to the pathobiology remain unknown. Pulmonary botryomycosis can resemble actinomycosis, tuberculosis, or invasive carcinoma by causing a mass lesion with constitutional symptoms. Radiographically, it invades bone and disrupts tissue planes. Successful treatment often requires a combination of both surgical debridement and long-term antimicrobial therapy. We report a case of primary pulmonary botryomycosis and review the literature on this unusual infectious process.
