Risk stratification of patients with diabetes and the role of sodium glucose co-transporter inhibitors 2 during Ramadan fasting

Evolving physicians' perceptions and practices regarding use of SGLT2 inhibitors for type 2 diabetes during Ramadan fasting

OBJECTIVES

We followed up the evolving perceptions and practices regarding use of SGLT-2 inhibitors in Ramadan.

METHODS

We compared results of the three survey in 2015, 2017, 2019.

RESULTS

Senior doctors represented 43.5-66.4% and endocrinologists accounted for 38.1-60.2%. There was a steady reduction in the proportions of respondents who did not know SGLT2-Is at all, who have just heard about the class and those who are quite familiar with the class but have not yet used any. Whereas the proportions of those using the SGLT2-Is class occasionally only was stable. However those who use the SGLT2-Is regularly increased from 11.0% to 45.6% and 62.6%. The respondents' who SGLT2-Is are safe and may be used in all fasting diabetic patients increased from 15.5%, 14.7% to 23.1%. Whereas the view that SGLT2-Is should not be used decreased progressively. Majority of respondents in the three surveys suggested that specific advice is given if they allow the use of SGLT2-Is during Ramadan. More respondents advise taking the medication with the first evening meal than before the last pre-dawn meal and advised to attend to their hydration status. One third of respondents would resume SGLT2-Is immediately after the end of Ramadan; 15% after 1-2 weeks, or prefer to wait till the next medical or educator's clinic visit and others would re-evaluate patients' management plan.

CONCLUSIONS

The medical professions' knowledge and perceptions regarding the use of SGLT2-Is during Ramadan fasting have evolved over the last few years due to increasing research and experience.

The South Asian Health Foundation (UK) guidelines for managing diabetes during Ramadan

BACKGROUND

Fasting in the holy month of Ramadan is among the five pillars of Islam and is considered as a religious obligation by the Muslim population. People with diabetes observing the practice of fasts are at a higher risk of complications such as hypoglycaemia, hyperglycaemia and ketoacidosis due to changes in eating patterns and circadian rhythms. With the objective of mitigating these complications, the South Asian Health Foundation (UK) has developed the present guidelines based on robust evidence derived from epidemiological studies and clinical trials.

METHODS

We have highlighted the role of pre-Ramadan risk stratification and counselling by healthcare professionals with emphasis on the need for advice on adequate dietary and fluid intake, blood glucose monitoring and awareness of when to break the fast.

RESULTS

We reviewed the current literature and have given clinically-relevant recommendations on lifestyle modifications and glucose-lowering therapies such as metformin, sulphonylureas, dipeptidyl peptidase-4 inhibitors, sodium glucose co-transporter-2 inhibitors, thiazolidinediones, glucagon-like peptide-1 receptor agonists and insulin.

CONCLUSIONS

An individualised patient-centric treatment plan is essential to not only achieve optimal glycaemic outcomes but also enable people with diabetes to observe a risk-free month of fasting during Ramadan.

Intermittent Fasting as Part of the Management for T2DM: from Animal Models to Human Clinical Studies

PURPOSE OF REVIEW

Diet is a pillar of type 2 diabetes mellitus (T2DM) management. Intermittent fasting (IF) is postulated as a novel approach, able to improve glucose control and potentially capable of reversing some of the pathophysiological alterations of this condition. In this review, the molecular and clinical evidence of diets based on intermittent energy restriction (IER) in laboratory animal models and subjects with type 2 diabetes is discussed. The mechanisms through which IF are thought to improve glucose homeostasis and reverse β cell failure are also reviewed.

RECENT FINDINGS

Studies derived from murine models suggest that IER is associated with improvements in β cell function and insulin resistance. Two main mechanisms have been demonstrated, one derived from the autophagy-lysosome pathway and, the other from an increase in neurogenin3 (Ngn3) levels (a marker for endocrine progenitor cells like β cells during development). Notably, IER also promotes reconstruction of gut microbiota. In mice, all effects were independent of weight loss. By contrast, in human studies, outcomes are widely attributable to weight loss. The more consistent results are reductions in body weight, visceral fat, and glucose and insulin levels. Increases in HDL cholesterol levels are also frequently reported. The decrease in insulin levels observed in humans is in opposition with the increase reported in mice, suggesting that the main mechanism in humans is an improvement in peripheral insulin action. Recommending diets based on intermittent fasting in humans is based on the promising results found in animal models where an improvement in β cell function has been recorded. β cell function after IF has not been assessed in human subjects with T2DM. This review provides information regarding different protocols for the implementation of IF in diabetic persons and also provides important safety advice in order to avoid adverse effects. Clinical studies do not show an increased risk of hypoglycemia, and a recent case series reported reversal of T2DM.

Risk of diabetic ketoacidosis during Ramadan fasting: A critical reappraisal

OBJECTIVES

To evaluate the validity of the perceived increased risk and the actual occurrence of DKA observed during fasting in Ramadan.

METHODS

This is a non-systematic narrative review of the literature on the occurrence of DKA during Ramadan. Online databases (PubMed, Google Scholar, Cochrane Database, Medline OVID and CINAHL EBSCO) were searched. Three research questions are addressed 1. What is the basis of the expert opinion on the risk for DKA? 2. What is the likelihood that DKA is precipitated by Ramadan fast? and 3. What is the frequency of observed DKA during Ramadan?

RESULTS

The expert opinion suggesting a risk of DKA during Ramadan fasting was proposed with no evidence in the early writing on Ramadan fasting and has been reiterated and propagated since then. However, from first principles, DKA is not readily precipitated by the usual stress-free metabolic environment induced by Ramadan fasting with the exception of cases involved in the usual risk factors for metabolic decompensation. Furthermore, recent studies could not document any increase in observed DKA during Ramadan fasting in retrospective, prospective and database studies.

CONCLUSIONS

The current state of knowledge and evidence suggests the risk of DKA is not increased during Ramadan fasting.
