The use of Free Style Libre Continues Glucose Monitoring (FSL-CGM) to monitor the impact of Ramadan fasting on glycemic changes and kidney function in high-risk patients with diabetes and chronic kidney disease stage 3 under optimal diabetes care.

AIM: To understand the risk of hypoglycaemia during Ramadan fasting by use of CGM, as well as to observe the Glycemic control and renal functions in patients with diabetes and chronic kidney disease stage 3 (CKD-3). METHOD: A prospective interventional study conducted in the Dubai Hospital, a tertiary care centre in the United Arab Emirates, during the month of Ramadan 1437 AH (Hijri), which corresponded to June 6th till July 5th, 2016. 25 patients with type 2 diabetes and stage 3 chronic kidney disease (CKD stage 3) were included in the study, who intended to fast during Ramadan. The aim was to observe the serum glucose level through 24 h FreeStyle Libre flash continuous glucose monitor (FSL-CGM). Most patients had three sensors during the study, covering an average three weeks during Ramadan and three weeks outside Ramadan (Sha'ban and shawal). We also monitored the change in, BP, HBA1c, kidney functions and BMI before and after Ramadan. RESULTS: This study included 25 adults with a mean age of 60 (±14 years). Fasting Ramadan did not result in any significant change in biophysical and biochemical profile of these patients. Data from FSL-CGM showed significantly longer duration (101.9 ±â€¯119.1 Vs. 45.9 ±â€¯47.6 min, p < 0.033) and more frequent hypoglycemic episodes (4.4 ±â€¯4.7 Vs. 2.3 ±â€¯3.0, p < 0.047) during Ramadan compared tonon-Ramadan respectively. The mean blood glucose readings were also significantly lower (70.7 ±â€¯29.3 Vs.93.7 ±â€¯57.9 mg/dl p < 0.011) during Ramadan compared to non -fasting period. The renal function mean ±â€¯SD (serum creatinine 1.48 ±â€¯0.37, 1.44 ±â€¯0.37 and eGFR, 49.0 ±â€¯18.4, 48.9 ±â€¯17.5 p 0.9) showed no significant change due to fasting. CONCLUSION: In patients with diabetes and CKD-stage 3 Ramadan fasting under close supervision and optimal diabetes care, was not associated with worsening of HBA1c and renal function. Patients had significantly more frequent and prolonged hypoglycemic episodes during Ramadan.

Assessment of risk of fasting during Ramadan under optimal diabetes care, in high-risk patients with diabetes and coronary heart disease through the use of FreeStyle Libre flash continuous glucose monitor (FSL-CGMS).

AIM: Most of Muslims patients with diabetes and Coronary Heart Disease (CHD) elect to fast in Ramadan, but the actual risk in this subset of patients with diabetes is largely unknown. We aimed to understand the safety of fasting in CHD patients with diabetes insisting on fasting Ramadan under optimal care. We also monitored the change in biophysical and biochemical parameters of these patients before and after Ramadan. We conducted this prospective study in a tertiary care hospital in Dubai during Ramadan 2016, (June 6th till July 5th). PATIENTS AND METHODS: 21 Patients with T2DM with stable known CHD during the three months prior to study and insisted on fasting despite advice against it were recruited for the study. All patients received continuous glucose monitoring with free style libre monitoring device (FSL-CGM) during and outside Ramadan period. We recorded DM or CVD-related emergency visit or hospitalisation, change in BMI, systolic and diastolic BP, lipids profile, e-GFR, HBA1c, and frequency of hypoglycemia during Ramadan fasting and not -fasting period. RESULTS: This is first study using CGM in CHD patients with diabetes who observe fast in Ramadan. Patients had a significantly higher incidence (3.2 ±â€¯2.8 vs 1.1 ±â€¯1.6 episodes, p = 0.033) and prolonged duration of hypoglycemia (117.8 ±â€¯87.2, 49.1 ±â€¯59.1 min p 0.022) during fasting compared to non-fasting respectively. No significant alteration was seen in BMI, SBP and DBP, lipid profile and renal function. There is a significant improvement in HBA1c during Ramadan. CONCLUSION: We could not associate any adverse cardiovascular effects with fasting Ramadan in patients with stable CHD under optimal diabetes care. FSL-CGMS data showed higher frequency of hypoglycemia during Ramadan fasting. Studies with larger sample size are needed for further validation of these findings.
