Comparative Outcomes of Bariatric Surgery in Patients With and Without Human Immunodeficiency Virus.
BACKGROUND: Paradoxically, advances in anti-retroviral therapy that has increased survival for patients with human immunodeficiency virus (HIV) have resulted in greater numbers of HIV+ patients developing other chronic diseases, including obesity. Little comparative literature exists detailing perioperative or metabolic outcomes of bariatric surgery in the HIV+ population compared to HIV negative (HIV-) controls. METHODS: This is a retrospective case-control study with both HIV+ (case) and HIV- control patients. Individuals undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between January 1, 2006 and December 31, 2015 were included. HIV+ status was defined as any individual with documented history of HIV. RESULTS: Eleven HIV+ patients underwent RYGB or SG during the study period. After matching (1:5 HIV+: HIV-) both cohorts had similar mean age (42 years), gender distribution (63% female), and preoperative BMI (48 kg/m2), as well as comorbidities. There were no differences in postoperative length of stay, or all cause 30-day morbidity. There were 63.7% HIV+ and 76.4% with 1-year follow-up available. Both percent excess weight loss (56% HIV+ vs. 60% HIV-) and BMI (32 HIV+ vs. 34 kg/m2 HIV-) were similar in both groups. There were minimal changes to CD4 count or HIV viral load in the patients during the follow-up period. CONCLUSION: Bariatric surgery is safe and feasible in HIV-infected population well controlled on anti-retroviral medication. The short-term surgical and metabolic outcomes are similar to HIV- controls with minimal effect on the CD4 count and viral load in HIV+ cohort for long-term follow-up.
