Clinical outcomes of Sodium-glucose cotransporter-2 inhibitors in patients with Type 2 Diabetes Mellitus: An observational study from Pakistan

OBJECTIVE: To determine the efficacy and safety of Sodium-glucose cotransporter-2 inhibitors (SGLT2i) use in the Pakistani population. METHODS: Retrospective review of initial 100 patients who were prescribed with any agent of the SGLT2i group from July 1, 2018, to January 2019 at Aga Khan University Hospital, Karachi. SGLT2i was offered to patients of above 18 years of age with inadequate glycemic control on existing antidiabetic agents. Changes in HbA1c, the Body Mass Index (BMI), serum creatinine, any decrease in the requirement of insulin and sulphonylurea dose along with any side effects reported by the patients on follow-up visits. RESULTS: Most study participants were females (56%) with the mean age of 52±10 years. Substantial changes were observed in the HbA1c (7.5±1.1%, 7.9±1.2% from 8.7±1.5%, p < 0.01), BMI (31.4±5.8, 31.8±5.8 from 32.4±5.9kg/m(2), p < 0.01) and in creatinine (0.71±0.1, 0.75±0.1 from 0.79±0.1 mg/dl, p < 0.01) at three and six months of follow up visits. The reduction in insulin and sulphonylurea doses was also significant. Adverse drug events that led to drug discontinuation in 14 individuals were, Urinary tract infection (UTI) (seven patients), Genital infection (three patients), nausea +UTI, abdominal pain +UTI, mild Diabetic Ketoacidosis, and polyuria (one patient each). None reported Fournier’s gangrene, limb amputation, or fracture. CONCLUSION: SGLT2i significantly improved glycemic control, BMI, and serum creatinine in the Pakistani population with a very low number of observed adverse events.
