Megestrol acetate vs cyproheptadine in the treatment of weight loss associated with HIV infection.

Two appetite stimulants, megestrol acetate and cyproheptadine were administered in a randomized trial to 14 patients who had no evidence of opportunistic infection or malabsorption but were wasted (had lost more than 5 kg body weight) as a result of human immunodeficiency virus (HIV) infection. Energy intakes were calculated from a 7 day weighed dietary record. Mean energy intakes per kilogramme body weight were similar in both treatment groups (greater than 34 kcal/kg) and were higher than that in well British males. Energy intakes increased by just over 500 kcal during both treatments, but fell to pretreatment levels after therapy. Patients in both treatment groups gained a moderate amount of weight. Megestrol acetate was associated with impotence in 4 patients. Insufficient calorie intake alone is not a common cause of wasting associated with HIV and the role of appetite stimulants is likely to be limited.

Health-related quality of life in individuals infected with HIV in the era of HAART.

PURPOSE: To compare health-related quality of life (HR-QOL) in individuals infected with HIV to general population levels and to assess the relationship between HR-QOL and markers of disease progression in the era of highly active antiretroviral therapy (HAART). METHOD: This was a cross-sectional questionnaire-based study. This study included 154 individuals at least 18 years old with HIV who either were attending a London hospital or were visited by a community team in Brighton. Study participants were asked to complete two HR-QOL questionnaires. This study used HR-QOL, as measured using the Medical Outcome Study HIV Health Survey (MOS-HIV) and EuroQoL self-report (EQ-5D) questionnaires, as the main outcome measure. Responses on the EQ-5D were compared with a published general population data set. The relationships between scores on the MOS-HIV and EQ-5D questionnaires and a number of independent variables including CD4 count and viral load were also assessed. RESULTS: Each analysis was based on the results of at least 128 questionnaires. The mean MOS-HIV mental and physical component scores were 43.2 (SD = 12.2) and 41.8 (SD = 13.2), respectively. After adjusting for differences in age and gender, it was shown that individuals with HIV reported significantly lower EQ-5D(utility) ( p =.0001) and EQ-5D(VAS) ( p =.0001) compared with the general population. However, further analysis revealed few significant associations between markers of disease progression and HR-QOL. CONCLUSION: Individuals with HIV generally recorded significantly lower HR-QOL compared with the general population. Thus, prevention of further transmissions of the virus is still likely to prevent significant morbidity losses in addition to mortality losses, despite the availability of HAART. However, disease progression as measured is not clearly related to further reductions in HR-QOL.

The cost-effectiveness of triple nucleoside analogue therapy antiretroviral regimens in the treatment of HIV in the United Kingdom.

PURPOSE: Treatment of HIV infection has improved markedly in recent years due to the use of combination antiretroviral therapies. However, the cost of these treatments remains a concern for those who fund health services. This article reports the results of an economic evaluation to determine the incremental cost-effectiveness of triple combination nucleoside analogue (NA) therapy compared with dual NA therapy. METHOD: A Markov model was developed to assess the incremental cost effectiveness of triple therapy treatment versus dual therapy treatment. Clinical data was derived from published clinical trials and large observational cohorts whilst cost data was derived from a prospective database that monitors health care resource use in the UK HIV population. RESULTS: The model predicted that triple NA combination treatment extended life expectancy by an additional 1.2 years compared with dual therapy NA treatment with an incremental cost-effectiveness ratio of 8,419 pounds per life-year saved. The incremental cost per quality-adjusted life-year (QALY) was estimated to be between 10,072-16,168 pounds per QALY gained depending on the assumptions. CONCLUSION: The results show triple nucleoside analogue therapy to be a cost effective means of delaying HIV progression and extending life expectancy. However, further research into this issue is warranted.

Intralesional vinblastine in the treatment of oral Kaposi's sarcoma.

Kaposi's sarcoma is a common tumour in HIV-infected patients, frequently involving the oropharynx. Conventional treatment with radiotherapy is efficacious, but causes considerable discomfort. This paper illustrates a new technique of local injection of vinblastine into oral lesions, which combines satisfactory palliation with high patient acceptability.
