BACKGROUND: Nevirapine, a nonnucleoside analogue, has demonstrated suppression of human immunodeficiency virus (HIV) replication alone and in combination therapy. However, the durable suppression of HIV with nevirapine when used along with other nucleosides in HIV-infected patients who are treated in clinical practice needs further evaluation. PURPOSE: To evaluate the sustained efficacy of nevirapine in combination with two nucleoside analogues in the treatment of HIV-infected patients in routine clinical practice. DESIGN: A multicenter study from January 1997 to December 2000, with follow-up through 48 weeks, was conducted at four different genitourinary medicine clinics in the United Kingdom. Forty-four HIV-infected patients received nevirapine and two nucleoside analogues. Information from case notes regarding age, sex, side effects, viral load, and CD4 lymphocyte counts at baseline, 24 weeks, and 48 weeks was collected and analyzed. Virologic suppression, defined as HIV RNA concentration of less than 400 copies/mL at Weeks 24 and 48, was considered as the main outcome measure. RESULTS: Out of 44 patients, 41 were men with a mean age of 39.3 years (95% CI 36.7-41.8). The baseline viral load was 2.11 x 10(2) to 9.74 x 10(5) copies/mL (median 7.7 x 10(4) and CD4 counts 6 to 605 cells/dL (M = 247; 95% CI 198-295). Of 39 patients who completed 48 weeks of treatment, viral load suppression was attained in 31 patients (79.4%; 95% CI 66.8-92.0) at 24 weeks and in 27 patients (69.2%; 95% CI 54-83) at 48 weeks. The CD4 lymphocyte count increased in 32 (82%) patients (mean 106 cells/dL, 95% CI 73-139, p =.0001, Wilcoxon signed rank test) after 24 weeks and in 33 (84.6%) patients (mean 160 cells/dL, 95% CI 115-204, p =.0001, Wilcoxon signed rank test) after 48 weeks of treatment. Of 20 patients whose baseline viral load was <100000, 16 had viral load suppressed at 24 weeks and 15 at 48 weeks (p =.6, chi-square test). CONCLUSION: A regime of nevirapine with two nucleoside analogues provided durable suppression of plasma viral load in HIV infected patients, with significant improvement in the CD4 cell count.

Necrotizing funisitis associated with Actinomyces meyeri infection: a case report.

Necrotizing funisitis is associated with an increased rate of stillbirth, perinatal infection, and preterm delivery. No one organism has been associated with necrotizing funisitis, although this condition has been linked with congenital syphilis in some studies. We report a case of necrotizing funisitis in a 24-year-old G2P0A2 woman who experienced preterm labor at 31 weeks of gestation. Examination of the placenta revealed severe chorioamnionitis and necrotizing funisitis; large numbers of gram-positive filamentous branching organisms could be seen on the surface of the cord and within Wharton jelly. Initial cultures of the placenta, which had not been maintained under anaerobic conditions after delivery, were negative. A fragment of the cord was then homogenized; anaerobic culture on brain-heart infusion agar yielded Actinomyces meyeri. This organism usually resides in the periodontal sulcus and has not been previously reported in the female genital tract. The mother gave a history of a dental abscess that flared up and drained with each of her three pregnancies; the pain was particularly severe during the last 2 months of this pregnancy, so she had the tooth removed after delivery. The infant was treated for prematurity and presumed sepsis and did well.

Treatment of external genital warts comparing cryotherapy (liquid nitrogen) and trichloroacetic acid.

BACKGROUND AND OBJECTIVES: To evaluate and compare the efficacy and adverse effects of trichloracetic acid and cryotherapy (using liquid nitrogen) in the treatment of external genital warts. STUDY DESIGN: Eighty-six patients were enrolled into a randomized clinical trial in the Genitourinary Medicine Department of the Coventry and Warwickshire Hospital (Coventry) between November 1990 and June 1991. External genital warts were treated with either trichloracetic acid or cryotherapy (using liquid nitrogen) on a once weekly basis. They received up to six treatments of either therapy. RESULTS: Complete clearance of warts in patients who received up to six treatments of cryotherapy were observed in 86% of cases and in 70% of patients who received up to six treatments of trichloracetic acid. Thirty percent of patients who were treated with trichloracetic acid developed ulcerations at the site of its application. CONCLUSION: In this study we found that cryotherapy (using liquid nitrogen) is more effective than that of trichloracetic acid for the treatment of external genital warts. It is also less likely to cause ulceration.
