DiaRem score predicts remission of type 2 diabetes after sleeve gastrectomy

 

Key clinical point: The DiaRem score is useful in predicting remission of type 2 diabetes following laparoscopic sleeve gastrectomy.

Major finding: Results of the DiaRem scores indicated that 58% of patients achieved complete remission of type 2 diabetes.

Study details: A retrospective analysis of 162 patients who underwent laparoscopic sleeve gastrectomy.

Disclosures: Dr. Rosenthal disclosed that he is a consultant for Medtronic. Dr. Lo Menzo reported having no financial disclosures.


 

AT THE ACS CLINICAL CONGRESS

 

– The DiaRem score was effective in predicting remission of type 2 diabetes following laparoscopic sleeve gastrectomy, results from a single-center study showed.

Developed by clinicians at Geisinger Clinic, the DiaRem is a simple score that helps predict remission of type 2 diabetes in severely obese subjects with metabolic syndrome who undergo Roux-en-Y gastric bypass surgery (Lancet Diabetes Endocrinol 2014;2[1]:38-45). The DiaRem score spans from 0 to 22 and is divided into five groups corresponding to five probability ranges for type 2 diabetes remission: 0-2 (88%-99%), 3-7 (64%-88%), 8-12 (23%-49%), 13-17 (11%-33%), 18-22 (2%-16%). In an effort to assess the feasibility of using the DiaRem score to predict remission of type 2 diabetes after laparoscopic sleeve gastrectomy, Raul J. Rosenthal, MD, FACS, and his associates conducted a 4-year retrospective review of 162 patients at the Cleveland Clinic Florida, Weston. “This is the first report that uses the DiaRem score for similar subjects that underwent sleeve gastrectomy instead,” Dr. Rosenthal said in an interview in advance of the annual clinical congress of the American College of Surgeons.

The mean age of the 162 patients was 55 years, 61% were women, 74% were non-Hispanic, their mean body mass index was 43.2 kg/m2, 33% had a preoperative hemoglobin A1c level between 7% and 8.9%, and 22% had an HbA1c of 9%. All had a minimum follow-up of 1 year after their laparoscopic sleeve gastrectomy and 67% had follow-up of 3 years or more, said Dr. Rosenthal, professor and chairman of the department of general surgery at Cleveland Clinic Florida.

Based on results of the DiaRem scores, 58% of patients achieved complete remission of type 2 diabetes, 6% achieved partial remission, and 36% had no remission. Specifically, 96% had DiaRem scores between 0 and 2; 92% had scores between 3 and 7; 50% had scores between 8 and 12, 20% had scores between 13 and 17, and 24% had scores between 18 and 22. “We were pleased to find out that 58% of patients that underwent sleeve gastrectomy achieved complete remission of type 2 diabetes mellitus,” said Dr. Rosenthal, who also directs the clinic’s bariatric and metabolic institute. “This compares favorably to previous reports in which patients achieved 33% of complete remission after gastric bypass.” The researchers also found that 84% of patients achieved remission in 12 months and the rest in 3 years. They observed medication reduction in 93% of the patients.

“Sleeve gastrectomy is a valid bariatric-metabolic procedure in patients with type 2 diabetes,” Dr. Rosenthal concluded. “The main limitation of this study is that is it a retrospective one, and we do not have a control group of patients that underwent gastric bypass or medical treatment to compare.”

The findings were presented at the meeting by Emanuele Lo Menzo, MD. Dr. Rosenthal disclosed that he is a consultant for Medtronic. Dr. Lo Menzo reported having no financial disclosures.
