Evaluation of efficacy and safety of itraconazole oral solution for the treatment of oropharyngeal candidiasis in aids patients.

This study was a non-comparative multicenter clinical trial to evaluate the efficacy and tolerability of itraconazole oral solution 200 mg/day (100 mg twice a day in the fasting state) for the treatment of oropharyngeal candidiasis in AIDS patients. We included 50 patients who were treated and followed for up to 3 weeks after ending therapy in the analysis. Mycological cures at the end of therapy occurred in 20/50 patients (40%), but colonization by Candida sp. was recorded in 42/50 (84%) by the end of follow-up. A high rate of clinical response was observed in 46/50 (92%), and the response was sustained for up to 21 days after stopping therapy in 24/46 patients (52%). Clinical relapses were documented among 22 patients, but all causative fungal organisms associated with a relapse were susceptible to itraconazole. There were many patients with persistence or recurrence of Candida, but without mucositis. Relapse of Candida mucositis was significantly related to low levels of CD(4) lymphocytes exhibited by symptomatic patients. The drug was well tolerated by all but 1 patient. We conclude that itraconazole oral solution (100 mg bid for 7-14 days) is a well tolerated and effective treatment for suppressing the symptoms of oropharyngeal candidiasis in AIDS patients. Patients with severe immunosuppression may relapse and require frequent cycles of treatment or longterm suppressive therapy.

Cellular and plasma viral load in patients infected with HIV-2.

OBJECTIVE: To determine circulating viral load in HIV-2-infected individuals. METHODS: Viral load was determined in 40 HIV-2-infected adults using standardized quantitative cell and qualitative plasma viraemia assays. We also tested for proviral HIV-2 DNA using single and nested polymerase chain reaction (PCR) in fresh lymphocytes from 27 subjects. The results were compared, on the basis of the CD4+ lymphocyte count, with our published data for HIV-1 infection. RESULTS: HIV-2 was isolated from peripheral blood mononuclear cells (PBMC) from 19 individuals and plasma from four patients. The rate of cell and plasma viraemia positivity correlated with the CD4+ cell count and HIV-2 virus load increased as the CD4+ cell count fell. The cellular HIV-2 load in the patients with a CD4+ count < 200 x 10(6)/l was similar to reported values for HIV-1, but the HIV-2 isolation rate from the plasma of these individuals was significantly lower than for HIV-1. When the CD4+ count was between 200 and 500 x 10(6)/l, the rate of HIV-2 isolation from plasma and the cellular virus load were both significantly lower than for HIV-1. When the CD4+ count was > 500 x 10(6)/l, HIV-1 and HIV-2 were undetectable in plasma and HIV-1 was isolated from PBMC in significantly more cases than HIV-2. By single PCR, amplification were positive in 14 out of 27 subjects and there was a correlation between positivity and CD4+ cell count. By nested PCR, only four of the 27 subjects, all with a high CD4+ count, remained negative. CONCLUSIONS: Differences in viral load between individuals infected with HIV-2 and those infected with HIV-1 could partly account for reported differences in the pathogenicity of the two viruses.

[Clinical and virological study of a case of infection with the HIV-LAV 2 virus]. / Etude clinique et virologique d'un cas d'infection par le virus HIV-LAV 2.

A case of AIDS due to HIV/LAV2 is reported. The patient was a 32 year old man from Guinea-Bissau with no known risk factors. He had brain toxoplasmosis, oral thrush and chronic genital herpes. Investigations for IgG anti-HIV/LAV1' (Elisa, Western Blot, Ripa) were negative. Antibodies to HIV/LAV2 were found and cultures of peripheral blood lymphocytes and cerebro-spinal fluid were positive. HIV/LAV2 seems to be similar to STLV-III (mac), STLV-III (agm), and probably HTLV-IV.
