Abstract

Background: Ramadan fasting by patients with type 1 diabetes might predispose them to hypoglycemia. There are no data on the optimal way of adjusting basal insulin during fasting. We aim at studying whether reducing basal insulin during Ramadan reduces the frequency of symptomatic hypoglycemia. Methods: We enrolled children and adolescents with type 1 diabetes who intended to fast during Ramadan. Logbooks were given to subjects to mark days fasted, symptomatic hypoglycemia, and dose of basal insulin on all days of Ramadan. Logbooks were examined. Glucometers and insulin pumps were downloaded. Results: Seventy-five patients were enrolled. The age was 10.2-18.9 (14.5) years. Sixty-eight patients had results analyzed. Forty-one patients were on pumps, and 27 patients were on multiple daily injections (MDI). Mean HbA1c was 7.9 (1.2) and 8.4 (1.3) for the pump and the MDI, respectively (P = 0.007). Thirty-nine patients had hypoglycemia leading to breaking fast. The mean number of episodes of breaking fast was 3 (1-8). Thirty-five of the 68 patients had reduced basal insulin. The difference in the frequency of hypoglycemia in those who reduced/did not reduce insulin was not statistically significant (P > 0.10). Fifteen patients on MDI and 24 patients on pumps had at least one episode of breaking fast. Six and 18 of the patients on MDI and pumps, respectively, reduced basal insulin (P > 0.10). Conclusion: This is the first study examining the impact of reduction of basal insulin on hypoglycemia in adolescents. Reducing basal insulin during Ramadan fasting does not decrease the risk of symptomatic hypoglycemia. Use of the insulin pump does not appear to be different from MDI in the frequency of occurrence of hypoglycemia.
