Effects of Ramadan fasting on platelet reactivity in diabetic patients treated with clopidogrel.

ABSTRACT: BACKGROUND:The effects of Ramadan fasting (RF) on clopidogrel antiplatelet inhibition were not previously investigated. The present study evaluated the influence of RF on platelet reactivity in patients with high cardiovascular risk (CVR) in particular those with type 2 diabetes mellitus (DM). METHODS:A total of 98 stable patients with ?2 CVR factors were recruited. All patients observed RF and were taking clopidogrel at a maintenance dose of 75 mg. Clinical findings and serum lipids data were recorded before Ramadan (Pre-R), at the last week of Ramadan (R) and 4 weeks after the end of Ramadan (Post-R). During each patient visit, nutrients intakes were calculated and platelet reactivity assessment using Verify Now P2Y12 assay was performed. RESULTS:In DM patients, the absolute PRU changes from baseline were +27 (p = 0.01) and +16 (p = 0.02) respectively at R and Post-R. In addition, there was a significant increase of glycemia and triglycerides levels with a significant decrease of high-density lipoprotein. In non DM patients there was no significant change in absolute PRU values and metabolic parameters. Clopidogrel resistance rate using 2 cut-off PRU values (235 and 208) did not change significantly in DM and non DM patients. CONCLUSIONS:RF significantly decreased platelet sensitivity to clopidogrel in DM patients during and after Ramadan. This effect is possibly related to an increase of glycemia and serum lipids levels induced by fasting. TRIAL REGISTRATION:Clinical Trials.gov NCT02720133.

Project description:ObjectivesIn the current study, we aimed at evaluating the effect of a culturally-based pre-Ramadan education program (PREP) on glycemic control, weight, adherence to post-sunset physical activity, perception of hypoglycemia, and anti-diabetic medication dose adjustment during Ramadan fasting in type 2 diabetics.Study designA total of 1008 type 2 Diabetes patients were offered a culturally-based PREP in addition to the standard of care, two months before Ramadan. A retrospective interview one month after Ramadan compared the fasting experience of PREP attendees (470 patients) with those who merely received standard of care (538 patients) (Non-PREP).ResultsRamadan fasting improved glycemic control with a correlation between HbA1c percent reduction and the number of fasting days (r?=?-0.290, p?=?0.007). More HbA1c and weight percent reduction were observed in PREP attendees compared to the Non-PREP group (-14.8%?±?9.3 vs. -5.4%?±?5.4; p?<?0.001; and?-?1.96%?±?5.4 vs. -0.39%?±?2.8; p?<?0.001, respectively). More commitment to night prayers in the PREP attendees compared to the Non-PREP group, (85.5% prayed >20 nights vs 28.4%; p?<?0.001) with more HbA1c and weight percent reduction in the those who performed the prayers more than 20 nights compared to those who performed no prayers (-11.69%?±?8.8 vs -6.28%?±?6.4, p?<?0.001; and?-?2.76% ±5.1 vs 1.35% ±1.8, p?<?0.001, respectively). More perception of true hypoglycemia was associated with PREP attendance (p0.046), insulin treatment (p0.000), and reduction of antidiabetic medication dosage (p0.004). Repeated lowering of antidiabetic medications doses with sequential downsizing of meals' portions, and appetite was reported.ConclusionRamadan fasting was beneficial for people with type 2 diabetes with reduction of HbA1c in correlation with the number of fasting days. Contrasting PREP with Non-PREP participants discovered better HbA1c and weight reduction in the former group even with equal number of fasting days. PREP participants performed more Taraweeh night prayers. The more the prayer nights the more decline of HbA1c and weight was observed. PREP improved perception and response to hypoglycemia with low-dosing of antidiabetic medications, especially insulin.
