['The efficacy and safety of bariatric surgery have been poorly studied in patients affected with HIV. Although sleeve gastrectomy (SG) is the most widely used procedure in many countries, most of the published literature reported results with the gastric bypass (GBP) procedure on morbidly obese HIV patients.', 'We have evaluated retrospectively, in eight consecutive patients who underwent a SG, its effect in weight loss and its impact on the treatment and on the markers of HIV infection.', 'Seven out of eight patients were females. The mean age was 46 years, with a median preoperative BMI of 42 kg/m(2). The mean duration of HIV infection and CD4 cell count were 13.4 years and 457 cells/mm(3), respectively. The mean weight loss was 37 kg in 20 months, the excess BMI loss was 80.8\u2009±\u200930.9 %, and the excess weight loss is 81.5\u2009±\u200928.9 % with one minor complication. CD4 counts were unchanged. Three patients had therapy modifications that were unrelated to bariatric surgery. Two patients had a therapeutic drug monitoring before and after the intervention. Plasma concentrations remained in therapeutic levels after the SG. Most comorbidities disappeared postoperatively, decreasing the cardiovascular risk.'] Is sleeve gastrectomy a safe and efficient procedure in HIV patients with morbid obesity : a case series with results in weight loss , comorbidity evolution , CD4 count , and viral load?
