Lack of reactivation of cytomegalovirus retinitis in an AIDS patient, during and after stopping long-term cidofovir treatment: case report.

The case of an AIDS patient with cytomegalovirus (CMV) retinitis who was treated with cidofovir for 17 consecutive months, without any adverse effect, is presented. In the context of antiretroviral therapy, cidofovir therapeutic regimen was 5 mg/kg of body weight for 2 weeks and 5 mg/kg thereafter every other week. Probenecid, hydration and monitoring for proteinuria were also used to prevent nephrotoxicity. The patient stopped maintenance therapy for CMV retinitis after the permanent rise of CD4+ cells above 100 c/mm3. For more than 10 months after drug withdrawal the patient remains free of retinitis.

Experience with adriamycin, bleomycin, vincristine (ABV) palliative chemotherapy in advanced AIDS-related Kaposi's sarcoma.

After administration of Adriamycin, bleomycin, vincristine (ABV) as palliative chemotherapy in advanced AIDS-related Kaposi's sarcoma (AIDS.KS) patients with low Karnosfsky performance scores, the authors attempted to estimate the overall biological cost/benefit relating to the disease. The authors analyzed data from 20 consecutive AIDS patients with advanced Kaposi's sarcoma presenting skin and visceral involvement treated with ABV every 3 weeks. An increased rate of infections, HIV and ABV-related side effects was observed. The performance amelioration (about 30%) was not significantly correlated with AIDS.KS clinical remission. CD4 count at baseline (p < 0.05), ABV therapy duration (p < 0.001), the achieved AIDS.KS clinical amelioration score (p < 0.01) and the improved Karnofsky score (p < 0.001) were significant predictors of life expectancy which was unrelated to the rate of side effects. The authors conclude that ABV palliative chemotherapy can assist in protracting life expectancy and improving the Karnofsky score.

Immune response to hepatitis A vaccination in HIV-infected men in Greece.

HIV-infected patients are at increased risk for acquiring hepatitis A virus (HAV) infection. We evaluated the seroconversion rate (anti-HAV antibodies ≥ 20 mIU/ml) and the geometric mean antibody titres (GMTs) in a group of 351 HIV infected men, who had received two doses of a hepatitis A vaccine. We analysed blood samples collected at one, six, 12 and 18 months following the administration of the second dose of the vaccine. The seroconversion rate one month after the second dose of the vaccine was 74.4% (260/351). At month 18 after the end of vaccination, 56.1% of the subjects remained seropositive. GMTs were 315, 203, 153 and 126 mIU/ml at months 1, 6, 12, and 18, respectively. Logistic regression revealed that the CD4 count is the only factor affecting response to vaccination (P = 0.019). A higher response rate and higher GMTs were observed in patients with CD4 counts ≥ 500 cells/mm(3) (76.6%) than in patients with CD4 counts 200-499 cells/mm(3). In conclusion, even in patients with near-normal CD4 counts, the response to the hepatitis A vaccine is impaired.

Re-evaluation of the natural course of bullous pemphigoid. A prospective study.

BACKGROUND: Few studies of prospectively collected data regarding the natural course of bullous pemphigoid have been performed. METHODS: The following factors were combined both quantitatively and qualitatively to obtain results: gender, clinical activity based on the estimation of the body area involvement, disease duration, relapses, coexistence with other disease states, and serology Twenty-seven consecutive patients were followed up for 1 year. RESULTS: Most disease activity (85.2%) is exhibited in the first year after onset. There is a lack of parameters with clear predictive significance. The extent and severity of skin involvement are equally distributed between the sexes and not affected by the disease duration. The generalized form of the disease is predominant (86.5%). The average clinical activity in relapses within the year of follow-up is 48% of the initially observed attack. The probability for recurrence is higher in seropositive patients (overall 37%). Coexistence with other disease states seems to be a random chance event. CONCLUSIONS: The lack of parameters with predictive importance underlines the necessity of a thorough follow-up to prevent treatment-related complications in elderly patients.

The impact of new antiretroic therapeutic schemes on the cost for AIDS treatment in Greece.

The paper attempts to evaluate the clinical and economic benefits between the administration of the dual and triple antiretroic schemes for the treatment of the HIV disease. Clinical and economic data are derived from patients hospitalized in 1996 and 1997 at the University Department of Dermatology and Venereology of Andreas Sygros Hospital. Methodology is based on the comparison of patients' nosological profile and direct annual cost before and after the administration of the triple treatment. The results of the study present that the triple combination therapy yields superior health outcomes, (decrease in the days of hospitalization and in the opportunistic disease events as well as fewer deaths and loss of production). Cost comparison presents a small decrease in the annual patient's cost, where all cost components are diminished, except the medication cost. A substitution of hospital care by drug therapy is revealed and a great change is taken place in the composition of the drugs' cost. Patient cost for antiretroic drugs has more than doubled from 1996 to 1997.
