Effect of a new insulin treatment regimen on glycaemic control and quality of life of Muslim patients with type 2 diabetes mellitus during Ramadan fast - an open label, controlled, multicentre, cluster randomised study

Safety and efficacy of different basal insulin in type 2 diabetes mellitus with chronic kidney disease in Ramadan: prospective observational study

BACKGROUND

Diabetic kidney disease populations are categorized as high risk for fasting in Ramadan due to various potential fasting-related complications. Insulin analogues are recommended to be used in place of human insulin during fasting, as they carry a lower risk of hypoglycaemia and stable glycaemic variability. A paucity of data exits on the safety and efficacy of different basal insulin types during fasting for this population. This study aims to evaluate the safety and efficacy of three basal insulin among patients with Type 2 Diabetes Mellitus and concomitant mild to moderate chronic kidney disease who are keen to fast during Ramadan.

MATERIALS AND METHODS

A single-centered, prospective observational study was conducted among 46 patients with type 2 diabetes mellitus and concomitant chronic kidney disease stage 2 and 3 who were on three different types of basal insulin (Glargine U-100, Levemir, and Insulatard), fasted in Ramadan 2022. All variables were listed as median (IQR). Hypoglycaemia events and glycemic variability obtained from Freestyle Libre continuous glucose monitoring were compared between insulin groups. Changes in glycated haemoglobin, fasting plasma glucose, renal profile, body weight, body mass index, and waist circumference pre and post-Ramadan were evaluated.

RESULTS

The glycaemic variability was found highest in Insulatard with a median (IQR) of 37.2(33)% versus Levemir 34.4(32.4)% versus Glargine U-100 36.8(30.6)%, p = NS. Levemir had reported the lowest median time of below range of 2.5(13)% followed by Glargine 4(25)% and Insulatard 5(8)%; p = NS. The findings of this study indicated that glycated haemoglobin, fasting plasma glucose, renal profile, body weight, body mass index, and waist circumference did not alter statistically between the three groups post-Ramadan. Individually, Insulatard showed a significant reduction in weight and waist circumference (0.9kg, p = 0.026; 0.44 cm, p = 0.008) while Levemir showed a reduction in waist circumference (0.75cm, p = 0.019).

CONCLUSION

This study revealed that Insulatard, Levemir, and Glargine demonstrated similar levels of safety and efficacy among those with diabetic kidney disease who observed fasting during Ramadan.

Interventions for people with type 2 diabetes mellitus fasting during Ramadan

BACKGROUND

Fasting during Ramadan is obligatory for adult Muslims, except those who have a medical illness. Many Muslims with type 2 diabetes (T2DM) choose to fast, which may increase their risks of hypoglycaemia and dehydration.

OBJECTIVES

To assess the effects of interventions for people with type 2 diabetes fasting during Ramadan.

SEARCH METHODS

We searched CENTRAL, MEDLINE, PsycINFO, CINAHL, WHO ICTRP and ClinicalTrials.gov (29 June 2022) without language restrictions.

SELECTION CRITERIA

Randomised controlled trials (RCTs) conducted during Ramadan that evaluated all pharmacological or behavioural interventions in Muslims with T2DM.

DATA COLLECTION AND ANALYSIS

Two authors screened and selected records, assessed risk of bias and extracted data independently. Discrepancies were resolved by a third author. For meta-analyses we used a random-effects model, with risk ratios (RRs) for dichotomous outcomes and mean differences (MDs) for continuous outcomes with their associated 95% confidence intervals (CIs). We assessed the certainty of evidence using the GRADE approach.

MAIN RESULTS

We included 17 RCTs with 5359 participants, with a four-week study duration and at least four weeks of follow-up. All studies had at least one high-risk domain in the risk of bias assessment. Four trials compared dipeptidyl-peptidase-4 (DPP-4) inhibitors with sulphonylurea. DPP-4 inhibitors may reduce hypoglycaemia compared to sulphonylureas (85/1237 versus 165/1258, RR 0.53, 95% CI 0.41 to 0.68; low-certainty evidence). Serious hypoglycaemia was similar between groups (no events were reported in two trials; 6/279 in the DPP-4 versus 4/278 in the sulphonylurea group was reported in one trial, RR 1.49, 95% CI 0.43 to 5.24; very low-certainty evidence). The evidence was very uncertain about the effects of DPP-4 inhibitors on adverse events other than hypoglycaemia (141/1207 versus 157/1219, RR 0.90, 95% CI 0.52 to 1.54) and HbA1c changes (MD -0.11%, 95% CI -0.57 to 0.36) (very low-certainty evidence for both outcomes). No deaths were reported (moderate-certainty evidence). Health-related quality of life (HRQoL) and treatment satisfaction were not evaluated. Two trials compared meglitinides with sulphonylurea. The evidence is very uncertain about the effect on hypoglycaemia (14/133 versus 21/140, RR 0.72, 95% CI 0.40 to 1.28) and HbA1c changes (MD 0.38%, 95% CI 0.35% to 0.41%) (very low-certainty evidence for both outcomes). Death, serious hypoglycaemic events, adverse events, treatment satisfaction and HRQoL were not evaluated. One trial compared sodium-glucose co-transporter-2 (SGLT-2) inhibitors with sulphonylurea. SGLT-2 may reduce hypoglycaemia compared to sulphonylurea (4/58 versus 13/52, RR 0.28, 95% CI 0.10 to 0.79; low-certainty evidence). The evidence was very uncertain for serious hypoglycaemia (one event reported in both groups, RR 0.90, 95% CI 0.06 to 13.97) and adverse events other than hypoglycaemia (20/58 versus 18/52, RR 1.00, 95% CI 0.60 to 1.67) (very low-certainty evidence for both outcomes). SGLT-2 inhibitors result in little or no difference in HbA1c (MD 0.27%, 95% CI -0.04 to 0.58; 1 trial, 110 participants; low-certainty evidence). Death, treatment satisfaction and HRQoL were not evaluated. Three trials compared glucagon-like peptide 1 (GLP-1) analogues with sulphonylurea. GLP-1 analogues may reduce hypoglycaemia compared to sulphonylurea (20/291 versus 48/305, RR 0.45, 95% CI 0.28 to 0.74; low-certainty evidence). The evidence was very uncertain for serious hypoglycaemia (0/91 versus 1/91, RR 0.33, 95% CI 0.01 to 7.99; very low-certainty evidence). The evidence suggests that GLP-1 analogues result in little to no difference in adverse events other than hypoglycaemia (78/244 versus 55/255, RR 1.50, 95% CI 0.86 to 2.61; very low-certainty evidence), treatment satisfaction (MD -0.18, 95% CI -3.18 to 2.82; very low-certainty evidence) or change in HbA1c (MD -0.04%, 95% CI -0.45% to 0.36%; 2 trials, 246 participants; low-certainty evidence). Death and HRQoL were not evaluated. Two trials compared insulin analogues with biphasic insulin. The evidence was very uncertain about the effects of insulin analogues on hypoglycaemia (47/256 versus 81/244, RR 0.43, 95% CI 0.13 to 1.40) and serious hypoglycaemia (4/131 versus 3/132, RR 1.34, 95% CI 0.31 to 5.89) (very low-certainty evidence for both outcomes). The evidence was very uncertain for the effect of insulin analogues on adverse effects other than hypoglycaemia (109/256 versus 114/244, RR 0.83, 95% CI 0.44 to 1.56; very low-certainty evidence), all-cause mortality (1/131 versus 0/132, RR 3.02, 95% CI 0.12 to 73.53; very low-certainty evidence) and HbA1c changes (MD 0.03%, 95% CI -0.17% to 0.23%; 1 trial, 245 participants; very low-certainty evidence). Treatment satisfaction and HRQoL were not evaluated. Two trials compared telemedicine with usual care. The evidence was very uncertain about the effect of telemedicine on hypoglycaemia compared with usual care (9/63 versus 23/58, RR 0.42, 95% CI 0.24 to 0.74; very low-certainty evidence), HRQoL (MD 0.06, 95% CI -0.03 to 0.15; very low-certainty evidence) and HbA1c change (MD -0.84%, 95% CI -1.51% to -0.17%; very low-certainty evidence). Death, serious hypoglycaemia, AEs other than hypoglycaemia and treatment satisfaction were not evaluated. Two trials compared Ramadan-focused patient education with usual care. The evidence was very uncertain about the effect of Ramadan-focused patient education on hypoglycaemia (49/213 versus 42/209, RR 1.17, 95% CI 0.82 to 1.66; very low-certainty evidence) and HbA1c change (MD -0.40%, 95% CI -0.73% to -0.06%; very low-certainty evidence). Death, serious hypoglycaemia, adverse events other than hypoglycaemia, treatment satisfaction and HRQoL were not evaluated. One trial compared drug dosage reduction with usual care. The evidence is very uncertain about the effect of drug dosage reduction on hypoglycaemia (19/452 versus 52/226, RR 0.18, 95% CI 0.11 to 0.30; very low-certainty evidence). No participants experienced adverse events other than hypoglycaemia during the study (very low-certainty evidence). Death, serious hypoglycaemia, treatment satisfaction, HbA1c change and HRQoL were not evaluated.

AUTHORS' CONCLUSIONS

There is no clear evidence of the benefits or harms of interventions for individuals with T2DM who fast during Ramadan. All results should be interpreted with caution due to concerns about risk of bias, imprecision and inconsistency between studies, which give rise to low- to very low-certainty evidence. Major outcomes, such as mortality, health-related quality of life and severe hypoglycaemia, were rarely evaluated. Sufficiently powered studies that examine the effects of various interventions on these outcomes are needed.

A Systematic Review of Insulin Management Recommendations to Improve Glycemic Control and Reduce Hypoglycemic Events During Ramadan Fasting in Patients With Insulin-Requiring Type 2 Diabetes

Background

Muslims with insulin-requiring type 2 diabetes are at high risk of hypo- and hyperglycemia while fasting during the month of Ramadan. Although a few reviews on diabetic management during Ramadan have been published, surveys reveal knowledge gaps remain among physicians.

Aim

This systematic review qualitatively analyzes what insulin dosing recommendations are likely to reduce hypoglycemic events and improve glycemic control during the Ramadan fasting for this high-risk group.

Methods

A comprehensive search in six databases and gray sources was performed from August 10, 2001, to August 10, 2021, for studies assessing which types of insulin and/or what dosing recommendations reduce hypoglycemic events and improve glycemic control during Ramadan. We excluded studies focusing mainly on oral antihyperglycemic medications, type 1 diabetes, persons with insulin pumps, and studies older than 20 years. Hypoglycemic event rates, pre-, and post-iftar blood glucose levels, overall average blood glucose, and hemoglobin A1c were analyzed, and a narrative synthesis was performed.

Results

Out of 1,101 collected articles, 14 eligible studies including 2,969 participants with an average age of 54.8 years, we found that insulin dose reduction may prevent hypoglycemia without causing subsequent hyperglycemia, and rapid-acting insulin analogs may improve post-iftar and overall blood glucose without incurring hypoglycemia.

Conclusions

Though initial findings are promising, more research is needed to confirm the benefits of insulin dose reduction, rapid-acting insulin analogs, and ultra-long-acting insulins.

Effect of Dosage Reduction of Hypoglycemic Multidrug Regimens on the Incidences of Acute Glycemic Complications in People With Type 2 Diabetes Who Fast During Ramaḍān: A Randomized Controlled Trial

OBJECTIVE

We aimed to investigate the effect of dosage reduction of four hypoglycemic multidrug regimens on the incidences of acute glycemic complications in people with type 2 diabetes who fast during Ramaḍān.

METHODS

We conducted an open-label, parallel-group, randomized controlled trial at a tertiary care center in Amman, Jordan. We recruited adults with type 2 diabetes who expressed an intention to fast during Ramaḍān and were adherent to one of four regimens-namely: metformin and glimepiride; metformin and vildagliptin; metformin and insulin glargine U100; or, metformin, insulin glargine U100, and human regular insulin. We randomly assigned participants in a 2:1 ratio to low- or regular-dosage therapy. The primary outcomes were the incidences of hypoglycemia and hyperglycemia during the 29 days of Ramaḍān 2017, and the secondary outcomes were the incidences of diabetic ketoacidosis and hyperosmolar hyperglycemic state during the same period.

RESULTS

We randomly assigned 687 participants to low-dosage therapy (n = 458) or regular-dosage therapy (n = 229) and included 678 (452 and 226, respectively) in the final analysis. The incidence of hypoglycemia was lower in the low-dosage group compared with the regular-dosage group (19 [4.2%] vs. 52 [23.0%], respectively; OR, 0.15 [95% CI, 0.08-0.26]; P < 0.001). The incidence of hyperglycemia did not differ between the low- and regular-dosage groups (319 [70.6%] vs. 154 [68.1%], respectively; OR, 1.12 [95% CI, 0.79-1.58]; P = 0.5). No participants experienced diabetic ketoacidosis or hyperosmolar hyperglycemic state. Each 1% decrease in the baseline HbA_1c concentration was associated with a 19.9-fold (95% CI, 9.6-41.5; P < 0.001) increase in the odds of hypoglycemia, and each 1% increase in the baseline HbA_1c concentration was associated with a 15.7-fold (95% CI, 10.0-24.6; P < 0.001) increase in the odds of hyperglycemia.

CONCLUSION

Dosage reduction decreases the incidence of hypoglycemia without a concomitant increase in the incidences of hyperglycemia, diabetic ketoacidosis, and hyperosmolar hyperglycemic state in people with type 2 diabetes who fast during Ramaḍān.

Impact of Ramadan Diurnal Intermittent Fasting on Hypoglycemic Events in Patients With Type 2 Diabetes: A Systematic Review of Randomized Controlled Trials and Observational Studies

Ramadan is the 9th month of the lunar calendar during which Muslims abstain from food and drink between dawn and sunset for 30 consecutive days. Ramadan fasting is observed by all healthy Muslim adults, as well many Muslims with type 2 diabetes (T2DM). Hypoglycemic events (HE) are a serious complication associated with diabetes management and are associated with increased cardiovascular disease risk. Conflicting results have been reported concerning the incidence of HE among people with T2DM observing Ramadan fasting. This review summarizes available scientific evidence on the occurrence of HE and the effects of different moderators on the incidence of HE among patients with T2DM during Ramadan. We conducted a systematic review of available observational studies and randomized controlled trials (RCTs) for patients with T2DM who fasted during Ramadan, with HE as the primary outcome. Ten databases were searched for relevant studies from inception until October 31, 2020. In total, 68 studies (35 RCTs and 33 observational studies) met the inclusion criteria. Non-sulfonylureas hypoglycemic medications showed superior effects in lowering the incidence of HE over sulfonylureas hypoglycemic medications. Variable moderators were associated with experiencing HE during Ramadan in both observational studies and RCTs, including sex, geographical location, body anthropometric indicators, season, dietary behaviors, fasting duration, time since diagnosis, and pre-fasting education. This comprehensive systematic review covered the largest number of observational and clinical studies investigating the impact of Ramadan on HE among patients with T2DM. The study highlights the significance of different moderators that influence the effect of Ramadan fasting on HE, including dietary behaviors, fasting time duration, sex, season, country, pre-fasting education, age, and time since diagnosis. The study also highlighted the impact of different hypoglycemic medications on HE and noted the superiority of non-sulfonylureas over sulfonylureas hypoglycemic medications in lowering the risk for hypoglycemia in people with T2DM during Ramadan fasting.

Comparison of Human Premixed and Basal Plus Short-Acting Insulin Regimens for Individuals With Type 2 Diabetes During Ramadan Fasting

Background Premixed insulin and basal insulin plus short-acting insulin regimens may be of value for treating individuals with type 2 diabetes (T2DM) who are fasting during Ramadan due to simplicity and better compliance. The objective of this study was to compare the effectiveness of human premixed insulin to basal plus short-acting insulin regimens in the management of fasting individuals with T2DM during Ramadan. Methods We conducted a prospective observational study in Basrah (southern Iraq) on 30 individuals with T2DM who fast during Ramadan. The enrolled patients were assigned into two groups at random: one group received a human premixed insulin regimen, the other received a basal plus short-acting insulin regimen. A baseline clinical and biochemical analysis was gathered for all patients at recruitment two weeks before fasting and within four weeks after the end of fasting. Patients were assessed twice during fasting month for insulin dose adjustment and documentation for any hyperglycemia or hypoglycemia. Results Fourteen patients were assigned to the premixed group, and 16 patients were assigned to the basal plus short-acting insulin group. The mean patient age was 53 ± 8 years, and the mean T2DM duration was 9.3 ± 4.2 years. The two groups were matched by age, body mass index, and glycated hemoglobin (HbA1c). There was no significant difference between the initial and final mean HbA1c in both groups. However, there was more non-significant HbA1c reduction in the premixed group as compared to the basal plus short-acting insulin group. The number of hypoglycemic events and weight changes among the two groups was not significant. Conclusions Both human premixed and basal plus short-acting insulin regimens are equally useful for glycemic control for patients with T2DM who choose to fast in observance of the month-long holiday of Ramadan.

Ramadan and Diabetes: A Narrative Review and Practice Update

Fasting in the Islamic month of Ramadan is obligatory for all sane, healthy adult Muslims. The length of the day varies significantly in temperate regions-typically lasting ≥ 18 h during peak summer in the UK. The synodic nature of the Islamic calendar means that Ramadan migrates across all four seasons over an approximately 33-year cycle. Despite valid exemptions, there is an intense desire to fast during this month, even among those who are considered to be at high risk, including many individuals with diabetes mellitus. In this review we explore the current scientific and clinical evidence on fasting in patients with diabetes mellitus, focussing on type 2 diabetes mellitus and type 1 diabetes mellitus, with brief reviews on pregnancy, pancreatic diabetes, bariatric surgery, the elderly population and current practice guidelines. We also make recommendations on the management of diabetes patients during the month of Ramadan. Many patients admit to a do-it-yourself approach to diabetes mellitus management during Ramadan, largely due to an under-appreciation of the risks and implications of the rigors of fasting on their health. Part of the issue may also lie with a healthcare professional's perceived inability to grasp the religious sensitivities of Muslims in relation to disease management. Thus, the pre-Ramadan assessment is crucial to ensure a safe Ramadan experience. Diabetes patients can be risk-stratified from low, medium to high or very high risk during the pre-Ramadan assessment and counselled accordingly. Those who are assessed to be at high to very high risk are advised not to fast. The current COVID-19 pandemic upgrades those in the high-risk category to very high risk; hence a significant number of diabetes patients may fall under the penumbra of the 'not to fast' advisory. We recognize that fasting is a personal choice and if a person chooses to fast despite advice to the contrary, he/she should be adequately supported and monitored closely during Ramadan and for a brief period thereafter. Current advancements in insulin delivery and glucose monitoring technologies are useful adjuncts to strategies for supporting type 1 diabetes patients considered to be high risk as well as 'high-risk' type 2 patients manage their diabetes during Ramadan. Although there is a lack of formal trial data, there is sufficient evidence across the different classes of therapeutic hypoglycaemic agents in terms of safety and efficacy to enable informed decision-making and provide a breadth of therapeutic options for the patient and the healthcare professional, even if the professional advice is to abstain. Thus, Ramadan provides an excellent opportunity for patient engagement to discuss important aspects of management, to improve control in the short term during Ramadan and to help the observants understand that the metabolic gains achieved during Ramadan are also sustainable in the other months of the year by maintaining a dietary and behavioural discipline. The application of this understanding can potentially prevent long-term complications.

Quality of life of Latin-American individuals with type 2 diabetes mellitus: A systematic review

OBJECTIVE

Diabetes mellitus is a serious public health problem that causes a decrease in the patients' quality of life. The present study was aimed to analyze the quality of life of patients with diabetes mellitus in Latin-American population through a systematic review, using the two instruments of greater validity and reliability at international level, SF-36 and WHOQOL.

METHODS

We performed extensive searches in Redalyc, SciELO, PubMed, Scopus and Web of Science databases. To delimit our search, we only included countries that are members of the Latin American Association of Diabetes. We identified 2168 articles, where 35 were considered relevant for this systematic review.

RESULTS

Our results showed that patients that regularly receive guidance and treatment to control the diabetes, showed better quality of life; in contrast, patients with foot ulcers or comorbidities showed the worse quality of life.

CONCLUSION

The current literature analysis suggests that this disease greatly influences in the quality of life of the patients.

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.

A systematic review on the safety of Ramadan fasting in high-risk patients with Diabetes

INTRODUCTION

Fasting the holy month of Ramadan is passionately practiced by all Muslim population around the world. Patients with diabetes are generally considered to have a higher risk of fasting. The current international guidelines have risk-stratified the patients with diabetes and other comorbidities to different categories, and the decision of fasting or not is made based on this categorization. Many studies looked at the impact of Ramadan fasting on those high-risk patients, and many are currently being in progress.

METHODS

In this systematic review, we conducted an extensive search in PubMed and google scholar engines. Studies filtration focused only on the Randomized controlled trial (RCT) and prospective observational studies accomplished between the year 2007 up to March2019 on impact of Ramadan on patients with diabetes at high risk of fasting.

RESULTS

The global dissemination and implementation of the guidelines for the management of diabetes during Ramadan broke the inertia among health care providers. Additionally, the concept of pre-Ramadan assessment for risk categorization, therapeutic doses modification in hand with self -monitoring blood glucose; have markedly reduced the risk and hospitalisation during Ramadan.

CONCLUSIONS

There is still limited data on fasting Ramadan by high risk patients with diabetes. There was minimal diversity in the published results, however, Generally and despite the education, self-titration; the incidences of complications during Ramadan is minimally higher than other times of the year in this group.

Impact of optimum diabetes care on the safety of fasting in Ramadan in adult patients with type 2 diabetes mellitus on insulin therapy

AIM

We aimed at evaluating the safety of fasting Ramadan for insulin treated type 2 diabetes patients by assessing the biochemical, biometric parameters, flash glucose monitoring (FGM) data as compared to pre-Ramadan and hospital admissions with diabetes or non-diabetes conditions. The risks of fasting between those treated with basal insulin vs intensive insulin during Ramadan was also assessed.

METHODS

We included insulin treated patients with type 2 diabetes and we excluded those with co-morbidities. Patients were provided with Ramadan-focused education, FGM before and during Ramadan and medical advice for treatment adjustment. We measured biologic and biometric data before and after Ramadan.

RESULTS

HbA1c reduced from 7.9 ± 1.20 pre-Ramadan to 7.7 ± 1.5% post Ramadan (p = 0.023). Average peak glucose reading was 330.1 ± 79.8 mg/dl before Ramadan improved significantly to reach 289.3 ± 77.7 mg/dl (p = 0.013). Average number of hypoglycemic episodes was higher in intensive insulin group between 1200 and 1800 h (p = 0.028).

CONCLUSION

People with type 2 diabetes treated with insulin who fast Ramadan and who are provided with Ramadan focused patient education, individualized treatment adjustment and FGMS were not at increased safety risks as measured by biochemical, biometric and FGM data.

A systematic review on efficacy and safety of the current hypoglycemic agents in patients with diabetes during Ramadan fasting

The fasting in the holy month of Ramadan is passionately practised among the Muslims population around the world. Patients with diabetes are generally considered to have various risks with fasting. The recent pharmacologic and technical advances in the management of diabetes may have enabled these patients to practice safe fasting. The purpose of this review is to scientific evidence on the safety and efficacy of the current hypoglycemic agents during Ramadan. METHODS: An extensive Electronic search via PubMed and Google scholar was accomplished through using different search terms. The eligible studies were limited to only published Randomised controlled trial (RCT) and prospective observational studies from 2007 to 2018 on patients with all types of diabetes on any pharmacological management, who intended to fast in Ramadan. RESULTS AND CONCLUSIONS: The current era witnessed a gradual shift in the management of these patients with diabetes who elected to fast in Ramadan, despite the variable health-related risks with fasting. Results from available RCTs and observational studies in patients with type 2 diabetes showed lower risk of hypoglycemia, similar or better efficacy for glycemic and weight control with SGLT2 inhibitors, incretin mimetics and the newer insulin analogues compared to Sulfonylurea. Gliclazide is a relatively safer option among all sulfonylurea. Patients requiring insulin did better with insulin analogues, especially the newer premixed formulation at the time of breaking fast compared to the former insulin formulation. Current commonly used newer hypoglycemic agents are generally safe during Ramadan, however, their safety in the higher risk diabetes patients is highly needed.

EADSG Guidelines: Insulin Therapy in Diabetes

A diagnosis of diabetes or hyperglycemia should be confirmed prior to ordering, dispensing, or administering insulin (A). Insulin is the primary treatment in all patients with type 1 diabetes mellitus (T1DM) (A). Typically, patients with T1DM will require initiation with multiple daily injections at the time of diagnosis. This is usually short-acting insulin or rapid-acting insulin analogue given 0 to 15 min before meals together with one or more daily separate injections of intermediate or long-acting insulin. Two or three premixed insulin injections per day may be used (A). The target glycated hemoglobin A1c (HbA1c) for all children with T1DM, including preschool children, is recommended to be < 7.5% (< 58 mmol/mol). The target is chosen aiming at minimizing hyperglycemia, severe hypoglycemia, hypoglycemic unawareness, and reducing the likelihood of development of long-term complications (B). For patients prone to glycemic variability, glycemic control is best evaluated by a combination of results with self-monitoring of blood glucose (SMBG) (B). Indications for exogenous insulin therapy in patients with type 2 diabetes mellitus (T2DM) include acute illness or surgery, pregnancy, glucose toxicity, contraindications to or failure to achieve goals with oral antidiabetic medications, and a need for flexible therapy (B). In T2DM patients, with regards to achieving glycemic goals, insulin is considered alone or in combination with oral agents when HbA1c is ≥ 7.5% (≥ 58 mmol/mol); and is essential for treatment in those with HbA1c ≥ 10% (≥ 86 mmol/mol), when diet, physical activity, and other antihyperglycemic agents have been optimally used (B). The preferred method of insulin initiation in T2DM is to begin by adding a long-acting (basal) insulin or once-daily premixed/co-formulation insulin or twice-daily premixed insulin, alone or in combination with glucagon-like peptide-1 receptor agonist (GLP-1 RA) or in combination with other oral antidiabetic drugs (OADs) (B). If the desired glucose targets are not met, rapid-acting or short-acting (bolus or prandial) insulin can be added at mealtime to control the expected postprandial raise in glucose. An insulin regimen should be adopted and individualized but should, to the extent possible, closely resemble a natural physiologic state and avoid, to the extent possible, wide fluctuating glucose levels (C). Blood glucose monitoring is an integral part of effective insulin therapy and should not be omitted in the patient's care plan. Fasting plasma glucose (FPG) values should be used to titrate basal insulin, whereas both FPG and postprandial glucose (PPG) values should be used to titrate mealtime insulin (B). Metformin combined with insulin is associated with decreased weight gain, lower insulin dose, and less hypoglycemia when compared with insulin alone (C). Oral medications should not be abruptly discontinued when starting insulin therapy because of the risk of rebound hyperglycemia (D). Analogue insulin is as effective as human insulin but is associated with less postprandial hyperglycemia and delayed hypoglycemia (B). The shortest needles (currently the 4-mm pen and 6-mm syringe needles) are safe, effective, and less painful and should be the first-line choice in all patient categories; intramuscular (IM) injections should be avoided, especially with long-acting insulins, because severe hypoglycemia may result; lipohypertrophy is a frequent complication of therapy that distorts insulin absorption, and therefore, injections and infusions should not be given into these lesions and correct site rotation will help prevent them (A). Many patients in East Africa reuse syringes for various reasons, including financial. This is not recommended by the manufacturer and there is an association between needle reuse and lipohypertrophy. However, patients who reuse needles should not be subjected to alarming claims of excessive morbidity from this practice (A). Health care authorities and planners should be alerted to the risks associated with syringe or pen needles 6 mm or longer in children (A).

Original paper: Efficacy and safety analysis of insulin degludec/insulin aspart compared with biphasic insulin aspart 30: A phase 3, multicentre, international, open-label, randomised, treat-to-target trial in patients with type 2 diabetes fasting during Ramadan

AIMS

To compare the efficacy and safety of insulin degludec/insulin aspart (IDegAsp) and biphasic insulin aspart 30 (BIAsp 30) before, during and after Ramadan in patients with type 2 diabetes mellitus (T2DM) who fasted during Ramadan.

METHODS

In this multinational, randomised, treat-to-target trial, patients with T2DM who intended to fast and were on basal, pre- or self-mixed insulin ± oral antidiabetic drugs for ≥90 days were randomised (1:1) to IDegAsp twice daily (BID) or BIAsp 30 BID. Treatment period included pre-Ramadan treatment initiation (with insulin titration for 8-20 weeks), Ramadan (4 weeks) and post-Ramadan (4 weeks). Insulin doses were reduced by 30-50% for the pre-dawn meal (suhur) on the first day of Ramadan, and readjusted to the pre-Ramadan levels at the end of Ramadan. Hypoglycaemia was analysed as overall (severe or plasma glucose <3.1 mmol/L [56 mg/dL]), nocturnal (00:01-05:59) or severe (requiring assistance of another person).

RESULTS

During the treatment period, IDegAsp (n = 131) had significantly lower overall and nocturnal hypoglycaemia rates with similar glycaemic efficacy, versus BIAsp 30 (n = 132). During Ramadan, despite achieving significantly lower pre-iftar (meal at sunset) self-measured plasma glucose (estimated treatment difference: -0.54 mmol/L [-1.02; -0.07]_{95% CI}, p = .0247; post hoc) with similar overall glycaemic efficacy, IDegAsp showed significantly lower overall and nocturnal hypoglycaemia rates versus BIAsp 30.

CONCLUSIONS

IDegAsp is a suitable therapeutic agent for patients who need insulin for sustained glucose control before, during and after Ramadan fasting, with a significantly lower risk of hypoglycaemia, versus BIAsp 30, an existing premixed insulin analogue.

Clinical practice points for diabetes management during RAMADAN fast

Diabetes management during Ramadan is very crucial from the patient perspective as it can present significant risk of hypoglycemia and death when proper care is not taken. Moreover, managing diabetes in fasting Ramadan patients require different mechanisms than the routine diabetes management and pose significant challenge to the health care practitioners. Here we set forth to review the available literature of various clinical trials and studies on different antidiabetic agents in the context of Ramadan. On the basis of available evidence, we suggest that gliclazide is effective and it could be safely recommended in type 2 diabetic patients fasting during Ramadan.

Telemonitoring in fasting individuals with Type 2 Diabetes Mellitus during Ramadan: A prospective, randomised controlled study

We determined the impact of a remote blood glucose telemonitoring program with feedback in type 2 diabetes mellitus patients fasting during Ramadan compared to conventional self-monitoring method. A twelve-week cluster randomised study, with 85 participants who wish to fast for at least 15 days during Ramadan was conducted. Self-measurement and transmission of blood glucose results were performed six times daily during Ramadan. Results were transmitted to a secure website for review with feedback from case manager if necessary. The control group received usual care. The main outcome was the number of participants experiencing hypoglycaemia during Ramadan and at the end of the study. During Ramadan, the number of participants reporting hypoglycaemia was significantly lower in the telemonitoring group [Odds ratio (OR): 0.186, 95% confidence interval: 0.04-0.936; p = 0.04]. Similarly, the proportion of participants reporting symptomatic hypoglycaemia at the end of the study was significantly lower in the telemonitoring group (OR: 0.257, 95% CI: 0.07-0.89; p = 0.03). A reduction of 1.07% in glycated haemoglobin levels was observed in the telemonitoring group compared to 0.24% in the control group (p < 0.01). Overall, telemonitoring was a useful adjunct to reduce the risk of hypoglycaemia during Ramadan with no deterioration in glycaemic control.

Diabetes and Ramadan: Practical guidelines

Ramadan fasting is one of the five pillars of Islam and is compulsory for all healthy Muslims from puberty onwards. Exemptions exist for people with serious medical conditions, including many with diabetes, but a large number will participate, often against medical advice. Ensuring the optimal care of these patients during Ramadan is crucial. The International Diabetes Federation (IDF) and Diabetes and Ramadan (DAR) International Alliance have come together to deliver comprehensive guidelines on this subject. The key areas covered include epidemiology, the physiology of fasting, risk stratification, nutrition advice and medication adjustment. The IDF-DAR Practical Guidelines should enhance knowledge surrounding the issue of diabetes and Ramadan fasting, thereby empowering healthcare professionals to give the most up-to-date advice and the best possible support to their patients during Ramadan.

Strategies to Make Ramadan Fasting Safer in Type 2 Diabetics: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials and Observational Studies

Ramadan is the holy month for Muslims whereby they fast from predawn to after sunset and is observed by all healthy Muslim adults as well as a large population of type 2 diabetic Muslims.To determine the comparative effectiveness of various strategies that have been used for type 2 diabetic Muslim who fast during Ramadan.A systematic review and network meta-analysis of randomized controlled studies (RCT) as well as observational studies for patients with type 2 diabetes who fasted during Ramadan was conducted. Eight databases were searched from January 1980 through October 2015 for relevant studies. Two reviewers independently screened and assessed study for eligibility, assessed the risk of bias, and extracted relevant data. A network meta-analysis for each outcome was fitted separately, combining direct and indirect evidence for each comparison.Twenty-nine studies, 16 RCTs and 13 observational studies each met the inclusion criteria. The most common strategy used was drug changes during the Ramadan period, which found that the use of DPP-4 (Dipeptidyl peptidase inhibitor -4) inhibitors were associated with a reduction in incidence of experiencing hypoglycemia during Ramadan in both RCTs (pooled relative risk: 0.56; 95% confidence interval: 0.44-0.72) as well as in observational studies (pooled relative risk: 0.27; 0.09-0.75). Ramadan-focused education was shown to be beneficial in reducing hypoglycemia in observational studies but not RCTs (0.25 versus 1.00). Network meta-analyses suggest that incretin mimetics can reduce the risk of hypoglycemia by nearly 1.5 times.The newer antidiabetic agents appear to lower the risk of hypoglycemia and improved glycemic control when compared with sulfonylureas. Ramadan-focused education shows to be a promising strategy but more rigorous examination from RCTs are required.
