BACKGROUND: Obese patients with preoperative gout often suffer of gouty attacks after bariatric surgery (BS), probably due to the lack of an adequate postoperative diet.
OBJECTIVES: The objectives of the study are to assess whether sleeve gastrectomy (SG) is effective in reducing the frequency of gouty attacks and also whether a postoperative low-purine diet (LPD) may further reduce these attacks as compared to a normal-purine diet (NPD) in a series of patients suffering of gout before SG.
METHODS: In this retrospective study, we measured and compared total body weight (TBW), body mass index (BMI), uric acid levels (UAL), anti-gout medication (allopurinol) requirements, and frequency in gouty attacks in 40 patients that underwent SG and who received either a LPD (n = 24) or NPD (n = 16). Compliance in following the prescribed diet was assessed in both groups study.
RESULTS: Before surgery, LPD and NPD patients had hyperuricemia and were receiving allopurinol. One year after SG, LPD and NPD groups showed a significant decrease in serum UAL (p < 0.001 and p = 0.00175, respectively). However, serum UAL decreased more significantly with the LPD compared to the NPD (p < 0.001). Furthermore, while NPD group showed a significant decrease in allopurinol requirements (p = 0.00130) and on the frequency in gouty attacks (p < 0.001), LPD group were off allopurinol therapy and had no gouty attacks 12 months after SG. Both groups showed high compliance in following the prescribed diets.
CONCLUSION: LPD is more effective in reducing the frequency of gouty attacks after SG compared with NPD in patients suffering of gout before surgery.
