Abstract

OBJECTIVE

To assess treatment adherence to dipeptidyl peptidase-4 inhibitor vildagliptin compared with sulphonylureas (SU) in Muslim patients with type 2 diabetes mellitus who were fasting during Ramadan in the UK.

RESEARCH DESIGN AND METHODS

This prospective, observational cohort study was conducted in four UK centres. Patients already taking vildagliptin (50 mg twice a day) or an SU as add-on therapy to metformin were followed up for ≤16 weeks. They were asked to record all missed doses of anti-diabetes medications.

RESULTS

Of the 72 patients enrolled (vildagliptin, n = 30; SU, n = 41; not allocated to treatment, n = 1), 59 (81.9%) completed the study (vildagliptin, n = 23; SU, n = 36), including one patient in the SU arm who completed but failed to provide information on missed doses; all patients in the SU arm were taking gliclazide. In the vildagliptin arm one patient (4.3%) missed a total of four doses while in the SU arm 10 patients (27.8%) missed a total of 266 doses (mean [SD] number of doses missed per patient: 26.6 [16.5]). The mean (SD) proportions of doses missed during fasting were 0.2% (0.9) and 10.4% (21.7) in the vildagliptin and SU arms, respectively, with a significant mean between-group difference of -10.2% (95% CI: -19.3%, -1.1%; p = 0.0292). There were no patients in the vildagliptin arm who missed more than 20% of OAD doses compared with 19.4% in the SU arm (p = 0.0358). Of the patients receiving an SU, 15 (42%) collectively reported 34 hypoglycaemic events (HEs) and one grade 2 HE; of these, fewer were non-adherent (n = 6, 40%) than adherent (n = 9, 60%). No patients reported HEs in the vildagliptin arm.

CONCLUSION

During Ramadan fasting, treatment with vildagliptin resulted in better treatment adherence compared with SU in Muslim patients with type 2 diabetes mellitus. Study limitations are the sample size and the lack of diet and exercise data.
