Fasting outcomes in people with diabetes and chronic kidney disease in East London during Ramadan 2018: The East London diabetes in Ramadan survey

Ramadan Fasting and Its Impact on Patients With Chronic Kidney Disease: Insights and Guidelines

Fasting during the month of Ramadan is a religious practice observed by millions of Muslims worldwide, including those with chronic kidney disease (CKD). This comprehensive review aims to reflect upon the impacts of Ramadan fasting on CKD patients, excluding those on renal replacement therapy, through an analysis of clinical trials, observational studies, and expert reviews from diverse geographic and methodological backgrounds. It addresses renal function stability, broader health considerations, hydration and electrolyte balance, individual variability in fasting responses, clinical and biochemical effects, nutritional considerations, and metabolic effects. This review reveals that, with appropriate monitoring, dietary management, and individualized care plans, many CKD patients can safely participate in Ramadan fasting without adversely affecting their renal function or overall health. It emphasizes the need for a multidisciplinary approach to patient education, pre-Ramadan assessment, and post-Ramadan follow-up. Furthermore, it highlights the importance of considering individual variability and comorbidities in fasting guidance and underscores the necessity of future research to develop robust, patient-centered fasting guidelines. This review aims to provide healthcare professionals with evidence-based recommendations to support CKD patients wishing to observe Ramadan fasting, ensuring patient safety and optimizing care outcomes.

Consensus recommendations on fasting during Ramadan for patients with kidney disease: review of available evidence and a call for action (RaK Initiative)

Ramadan fasting (RF) involves abstaining from food and drink during daylight hours; it is obligatory for all healthy Muslims from the age of puberty. Although sick individuals are exempt from fasting, many will fast anyway. This article explores the impact of RF on individuals with kidney diseases through a comprehensive review of existing literature and consensus recommendations. This study was conducted by a multidisciplinary panel of experts.The recommendations aim to provide a structured approach to assess and manage fasting during Ramadan for patients with kidney diseases, empowering both healthcare providers and patients to make informed decisions while considering their unique circumstances.

The Impact of Hot Ambient Temperature and Prolonged Fasting Duration during Ramadan on Patients with Chronic Kidney Disease: A Literature Review

The Islamic (lunar) calendar has 11 fewer days each year than the Gregorian (solar) calendar. Consequently, ambient temperatures during the month of Ramadan and the duration of the presunrise-to-sunset fast will change each year. At some point, individuals observing Ramadan will experience prolonged periods of fasting during the hot summer months. In this manuscript, findings published in the English-language medical literature that address the impact of prolonged fasting during the warmer summer months on patients with chronic kidney disease, including dialysis and transplantation patients, are reviewed. This is of particular concern given the accelerated pace of global warming. The limitations of the evidence that is currently available are also discussed, and an approach that might be used to standardize future evaluations of the impact of fasting on kidney health is suggested.

Ramadan fasting in people with diabetes and chronic kidney disease (CKD) during the COVID-19 pandemic: The DaR global survey

BACKGROUND AND AIMS

The DaR Global survey was conducted to observe the impact of the COVID-19 pandemic on the intentions to fast and the outcomes of fasting in people with diabetes and chronic kidney disease (CKD).

METHODS

Muslim people with diabetes and CKD were surveyed in 13 countries shortly after the end of Ramadan 2020, using a simple Survey Monkey questionnaire.

RESULTS

This survey recruited 6736 people with diabetes, of which 707 (10.49%) had CKD. There were 118 (16.69%) people with type1 diabetes (T1D), and 589 (83.31%) were with type2 diabetes (T2D). 62 (65.24%) people with T1D and 448 (76.06%) people with T2D had fasted with CKD. Episodes of hypoglycaemia and hyperglycaemia were more frequent among people with T1D compared to T2D, 64.52% and 43.54% vs 25.22% and 22.32% respectively. Visits to the emergency department and hospitalization were more frequent among people with CKD, however no significant difference was found between people with T1D and T2D.

CONCLUSION

The COVID-19 pandemic had only a minor effect on the intention to fast during Ramadan in people with diabetes and CKD. However, hypoglycaemia and hyperglycaemia were found to be more frequent, as well as emergency visits and hospital admissions among people with diabetic kidney disease. Prospective studies are needed in future to evaluate the risk indicators of hypoglycaemia and hyperglycaemia among fasting people with CKD, especially in the context of different stages of kidney disease.

Cross-sectional study of household solid fuel use and renal function in older adults in China

BACKGROUND

Emerging evidence links outdoor air pollution and declined renal function but the relationship between household air pollution and renal function is not well understood.

METHODS

Using cross-sectional data from the multi-provincial INTERMAP-China Prospective Study, we collected blood samples and questionnaire information on stove use and socio-demographic factors. We calculated estimated glomerular filtration rate (eGFR) from serum creatinine to assess renal function. Participants with eGFR <60 mL/min per 1.73 m2 were defined as having chronic kidney disease (CKD) in this analysis. Generalized estimating equations were used to estimate the association of household fuel with renal function and prevalent CKD in models adjusting for confounders.

RESULTS

Among the 646 enrolled adults (40-79y; 56% female), one-third exclusively used clean fuel (gas and electric) cookstoves and 11% of northern China participants (n = 49 of 434) used only clean fuel heaters, whereas the rest used solid fuel. In multivariable models, use of solid fuel cookstoves was associated with 0.17 ml/min/1.73 m2 (95% CI: -0.30, 0.64) higher eGFR and 19% (0.86, 1.64) higher prevalence of CKD than exclusive clean fuel use. Greater intensity of solid fuel use was associated with 0.25 ml/min/1.73 m2 (-0.71, 0.21) lower eGFR per 5 stove-use years, though the confidence intervals included the null, while greater current intensity of indoor solid fuel use was associated with 1.02 (1.00, 1.04) higher prevalent CKD per 100 stove-use days per year. Larger associations between current solid fuel use and intensity of use with lower eGFR and prevalent CKD were observed among participants in southern China, those with hypertension or diabetes (eGFR only), and females (CKD only), through these groups had small sample sizes and some confidence intervals included the null.

CONCLUSION

We found inconsistent evidence associating household solid fuel use and renal function in this cross-sectional study of peri-urban Chinese adults.

Religious fasting and its impacts on individual, public, and planetary health: Fasting as a "religious health asset" for a healthier, more equitable, and sustainable society

Religious fasting is practiced by people of all faiths, including Christianity, Islam, Buddhism, Jainism, as well as Hinduism, Judaism, and Taoism. Individual/clinical, public, global, and planetary health has traditionally been studied as separate entities. Nevertheless, religious fasting, in conjunction with other religious health assets, can provide several opportunities, ranging from the individual to the population, environmental, and planetary levels, by facilitating and supporting societal transformations and changes, such as the adoption of healthier, more equitable, and sustainable lifestyles, therein preserving the Earth's systems and addressing major interconnected, cascading, and compound challenges. In this review, we will summarize the most recent evidence on the effects of religious fasting, particularly Orthodox and Ramadan Islamic fasting, on human and public health. Further, we will explore the potential effects of religious fasting on tackling current environmental issues, with a special focus on nutrition/food restriction and planetary health. Finally, specific recommendations, particularly around dietary intake during the fasting rituals, will be provided to ensure a sustainable healthy planet.

Dietary Risk Factors and Eating Behaviors in Peripheral Arterial Disease (PAD)

Dietary risk factors play a fundamental role in the prevention and progression of atherosclerosis and PAD (Peripheral Arterial Disease). The impact of nutrition, however, defined as the process of taking in food and using it for growth, metabolism and repair, remains undefined with regard to PAD. This article describes the interplay between nutrition and the development/progression of PAD. We reviewed 688 articles, including key articles, narrative and systematic reviews, meta-analyses and clinical studies. We analyzed the interaction between nutrition and PAD predictors, and subsequently created four descriptive tables to summarize the relationship between PAD, dietary risk factors and outcomes. We comprehensively reviewed the role of well-studied diets (Mediterranean, vegetarian/vegan, low-carbohydrate ketogenic and intermittent fasting diet) and prevalent eating behaviors (emotional and binge eating, night eating and sleeping disorders, anorexia, bulimia, skipping meals, home cooking and fast/ultra-processed food consumption) on the traditional risk factors of PAD. Moreover, we analyzed the interplay between PAD and nutritional status, nutrients, dietary patterns and eating habits. Dietary patterns and eating disorders affect the development and progression of PAD, as well as its disabling complications including major adverse cardiovascular events (MACE) and major adverse limb events (MALE). Nutrition and dietary risk factor modification are important targets to reduce the risk of PAD as well as the subsequent development of MACE and MALE.

Fasting Ramadan in Chronic Kidney Disease (CKD), Kidney Transplant and Dialysis Patients: Review and Update

Chronic kidney disease (CKD) is a common disease in the Islamic regions. Dehydration occurs after prolonged fasting, particularly in hot and humid climates. In the Arabic months’ calendar, Ramadan is a month of maximum given deeds, where Muslims are required to fast from dawn till sunset. Depending on where you live and when the Ramadan month falls, fasting might last anywhere from 10 to 20 hours or more. In certain circumstances, such as poorly controlled diabetes and advanced CKD patients who are allowed to break their fast, the Ramadan fasting amendment is viable. Some Muslims, however, continue fasting despite these circumstances, placing themselves at risk, which is not allowed in the Islamic religion.

There are no medical recommendations that specify who should and should not fast. Nonetheless, the recommendations have been extracted from several published studies. The authors searched EMBASE, PubMed, Google Scholar, and Google for publications, research, and reviews. All authors debate and analyze the related articles. Each author was assigned a part or two of the topics to read, study, and summarize before creating the final draft of their given section. Then this comprehensive review was completed after discussion sessions.

In conclusion, by the Islamic religion view, fasting Ramadan is mandatory for every wise adult person. People who have chronic diseases or that may deteriorate by fasting are exempted from fasting. It seems that fasting and the associated disease hours are determinant factors to fasting or not fasting. Up to our knowledge, there are no established guidelines for CKD patients and physicians to follow; however, the International Diabetes Federation and Diabetes and Ramadan (IDF-DAR) Practical Guidelines 2021 have been issued for CKD diabetic patients and fasting.

Caloric and Lipid Profiles in the Spanish Population of North Africa

This study introduces an analysis for determining factors of diet quality among the Spanish adult population in North Africa with the aim of promoting healthier eating habits to prevent the development of diabetes mellitus. It is a diagnostic, non-experimental, cross-sectional and observational study, with a descriptive correlational methodology, with 201 participants from Ceuta and Melilla. The information collection has been carried out through the 24 h diet recall. Various sociodemographic factors influencing the quality of the diet have been analyzed. People from Melilla adopt a carbohydrate-rich diet (p = 0.004), whereas people from Ceuta have a lipid-rich diet (p = 0.002), particularly a high- monounsaturated-fat diet (p = 0.007). Muslims consume more sugar (p = 0.001) compared with Christians. Those working consume less carbohydrates (p = 0.13) than those not working. The latter consuming more fats (p = 0.39), and those with a higher education level show higher consumption of proteins (p = 0.001). The results of this study suggest that diet quality, in general, does not follow healthy recommendations established for the Spanish population, where the sugar consumption-diabetes relationship justifies the need for further research on Muslim population.

Impact of fasting during ramadan on renal functions in patients with chronic kidney disease

Introduction:

The impact of Ramadan fasting in patients with chronic kidney disease (CKD) remains less studied and with inconsistent results. In this study, we tried to look at the impact of Ramadan fasting on renal function in patients with CKD.

Materials and Methods:

In this prospective observational study, we included 28 adult CKD patients. All relevant biochemical parameters including renal function tests were done in the month before Ramadan fasting and within 3 months after Ramadan. Urine output, body weight, and blood pressure were also monitored during Ramadan and after the end of Ramadan for at least 10 days.

Results:

All the 28 patients (mean age: 46 ± 12 years) included in the study managed to fast for the whole month, and none displayed any new clinical symptoms or signs. The renal function worsened in four (14.28%), and it was significant in those with CKD Stages 4 and 5 (P < 0.003).

Conclusion:

Stable CKD patients can fast with careful monitoring; however, there is a risk of renal function deterioration in advanced CKD.

Effect of Ramadan fasting on renal function of people with diabetes; a prospective longitudinal study

AIM

To observe the effect of Ramadan fasting on renal function of people with diabetes.

METHODS

This prospective, observational, and longitudinal study was conducted at Baqai Institute of Diabetology and Endocrinology, between April-July 2019. People with type2 diabetes mellitus were recruited using convenient sampling. Demographic data along with renal function were recorded before Ramadan. Kidney functions were assessed in those who came for follow up at 6 weeks, 3 months, and a year after Ramadan.

RESULTS

A total of seventy people with diabetes participated in this study with the mean age of 53.11 ± 8.70 years. A significant decline in eGFR was noted around six weeks post Ramadan with a significant improvement of eGFR at 3 months follow-up. The normalization of kidney functions among the study participants was observed even after one year of Ramadan.

CONCLUSION

In this study post Ramadan assessment of creatinine clearance showed a significant fall among fasting people with diabetes though remained with in normal limits. Significant improvement and reversal of kidney functions was noted in those who followed within three months' time.

Does daily fasting shielding kidney on hyperglycemia-related inflammatory cytokine via TNF-α, NLRP3, TGF-β1 and VCAM-1 mRNA expression

This study aimed to investigate the effects of blood glucose control and the kidneys' functions, depending on fasting, in the streptozotocin-induced diabetes model in rats via TNF-α, NLRP-3, TGF-β1 and VCAM-1 mRNA expression in the present study. 32 Wistar albino rats were allocated randomly into four main groups; H (Healthy, n = 6), HF (Healthy fasting, n = 6), D (Diabetes, n = 10), DF (Diabetes and fasting, n = 10). Blood glucose and HbA1c levels significantly increased in the D group compared to the healthy ones (p < 0.05). However, the fasting period significantly improved blood glucose and HbA1c levels 14 days after STZ induced diabetes in rats compared to the D group. Similar findings we obtained for serum (BUN-creatinine) and urine samples (creatinine and urea levels). STZ induced high glucose levels significantly up-regulated TNF-α, NLRP-3, TGF-β1 and VCAM-1 mRNA expression and fasting significantly decreased these parameters when compared to diabetic rats. Histopathological staining also demonstrated the protective effects of fasting on diabetic kidney tissue. In conclusion, intermittent fasting regulated blood glucose level as well as decreasing harmful effects of diabetes on kidney tissue. The fasting period significantly decreased the hyperglycemia-related inflammatory cytokine damage on kidneys and also reduced apoptosis in favor of living organisms.

The effect of Fasting during Ramadan on the Kidney functions of Stage III-IV Chronic Kidney Disease Patients

OBJECTIVES

Examine the effect of fasting during Ramadan on kidney functions in patients with chronic kidney disease.

METHODS

The study was conducted on 130 patients with stage III-IV chronic kidney disease (CKD), who were admitted to the Ordu University nephrology polyclinic during the month before Ramadan and one month after Ramadan in 2019. Blood samples were taken in the morning after 12 hours of fasting.

RESULTS

There was a statistically significant difference between BUN in the fasting group before and after the month of Ramadan. The median BUN before Ramadan was 26.65 mg/dl, the median after Ramadan was 24.05 mg/dl (p=0.004).There was a statistically significant difference between the nonfasting groups before and after Ramadan with respect to creatinine level. Median creatinine before Ramadan was 1.69 mg/dl,and the median after Ramadan was 1.86 mg/dl (p <0.001).There was a statistically significant difference between the fasting groups before and after Ramadan with respect to creatinine levels. Fasting group ,the median before Ramadan was 1.5 mg/dl, and the median after Ramadan was 1.42 mg/dl (p = 0.038).The impact of independent variable of fasting, using linear regression was found to be statistically significant (ppost-<0.001). The eGFR was 14.826 points higher in those who fasted after Ramadan than in those who did not.

CONCLUSION

Fasting during the month of Ramadan does not deteriorate kidney functions and even leads to a moderate improvement in kidney functions. Taking these results into consideration, fasting may be advised for patients with stage III-IV CKD who want to fast and remain in stable condition.

Effects of fasting on patients with chronic kidney disease during Ramadan and practical guidance for healthcare professionals

There are an estimated 1.8 billion Muslims worldwide, with the majority of them choosing to fast during the month of Ramadan. Fasting, which requires abstinence from food and drink from dawn to sunset can be up to 20 h per day during the summer months in temperate regions. Fasting can be especially challenging in patients on haemodialysis and peritoneal dialysis. Moreover, there is concern that those with chronic kidney disease (CKD) can experience electrolyte imbalance and worsening of renal function. In this article, current literature is reviewed and a decision-making management tool has been developed to assist clinicians in discussing the risks of fasting in patients with CKD, with consideration also given to circumstances such as the coronavirus disease 2019 pandemic. Our review highlights that patients with CKD wishing to fast should undergo a thorough risk assessment ideally within a month before Ramadan, as they may require medication changes and a plan for regular monitoring of renal function and electrolytes in order to fast safely. Recommendations have been based on risk tiers (very high risk, high risk and low-moderate risk) established by the International Diabetes Federation and the Diabetes and Ramadan International Alliance. Patients in the very high risk and high risk categories should be encouraged to explore alternative options to fasting, while those in the low-moderate category may be able to fast safely with guidance from their clinician. Prior to the commencement of Ramadan, all patients must receive up-to-date education on sick-day rules and instructions on when to terminate their fast or abstain from fasting.

Ramadan fasting and diabetes 2019: The year in review

INTRODUCTION

The literature on health aspects of Ramadan fasting is widely spread in many journals making it not readily available to those interested in the subject.

MATERIALS AND METHODS

A narrative, non-systematic review of the international literature from two major online databases (viz. Scopus, PubMed) in one year (2019). The search term "Ramadan fasting AND Diabetes" was used, and relevant literature was narrated in a concise thematic account.

RESULTS

Research design included qualitative, quantitative, and mixed methods. Articles included controlled trials, critical appraisals, literature narrations, and systematic reviews, and meta-analyses. The publications spanned a vast array of topics related to Ramadan fasting, including assessments of current safety and efficacy profiles of newer diabetes therapies, modes of insulin delivery, and utilization of advanced technology for the treatment and monitoring of blood glucose during Ramadan fasting. Increased interest was particularly evident in capturing the experience element manifested by perceptions, attitudes, and practices of both patients and healthcare professionals during Ramadan. The current literature consolidates previous data on the safety of fasting practices amongst the well-controlled. On the other hand, it emphasizes the need for more aggressive interventions for high-risk patients, promoting the usage of newer anti-diabetic agents and advanced glucose monitoring technology for safer fasting practices.

CONCLUSIONS

The volume of global literature production related to Ramadan fasting and Diabetes remains modest. Observational studies of small size prevail. Greater improvements in both quality and quantity of research on Ramadan are needed.

Dietary knowledge, preferences and behaviors in Ramadan among Muslim patients with type 2 diabetes

AIMS

To explore the association between dietary knowledge, attitude, and practices during Ramadan among Muslim patients with type 2 diabetes.

METHODS

Recruited after Ramadan from public clinics and a hospital in Banda Aceh, Indonesia, 401 outpatients recalled their food consumption frequencies of high-fiber food, deep-fried food, and high-sugar dessert, and relevant knowledge and attitudes. Multivariable logistic regression models were applied to examine the research questions.

RESULTS

Vegetable consumption and preference were both high among the patients. However, only 4.5% knew that brown rice is rich in fiber, and 19% agreed that whole-grain foods were accessible. Deep-fried food consumption and its availability at home was common, even though the majority considered it should be avoided. Patients with a lower preference for deep-fried foods were less likely to consume deep-fried foods during Ramadan (OR = 0.239, 95% CI = 0.109-0.523, p = 0.001). Knowledge of the glycemic index's health implication was associated with more high-fiber foods consumption (OR = 2.733, 95% CI = 1.179-6.332, p = 0.019). Yet, knowing the potential risk of added sugar on blood glucose level was associated with high-sugar dessert consumption (OR = 2.997, 95% CI = 1.482-6.060, p = 0.002).

CONCLUSION

The patients' low consumption of whole-grain food and common comsumption of deep-fried food during Ramadan would be the first priority to be improved. Along with dietary knowledge and attitude, food environment could be an important factor that influences patients' dietary behaviors.

Ramadan fasting among advanced chronic kidney disease patients. Nephrologists' perspectives in Saudi Arabia

Objectives:

To explore nephrologists’ concerns and recommendations in counseling their advanced chronic kidney disease (CKD) patients on Ramadan fasting.

Methods:

This cross-sectional study was carried out in King Khalid University Hospital, Riyadh, Saudi Arabia between January 2019 and January 2020. An electronic survey was completed by 48 nephrologists practicing in Saudi Arabia. The questionnaire focused on demographics, clinical experience, and factors to consider when advising CKD patients about fasting. Statistical analysis was performed by the Statistical Package for Social Sciences for Windows, version 21 (IBM Corp, Armonk, NY, USA). Statistics include frequency and percentages using multiple response dichotomy analysis and thematic analysis.

Results:

Most respondents were consultant nephrologists (75%), practicing nephrology for over 10 years (68.8%). The majority of responding nephrologists (85.4%) were concerned about estimated glomerular filtration rate (eGFR), diabetes (68.8%), patient age (64.6%), use of diuretics (62.5%), body fluid volume (60.4%), and blood pressure (60.4%).

Conclusion:

This research addresses nephrologists’ perspectives about Ramadan fasting for patients with advanced CKD. It highlights factors they consider when advising CKD patients about fasting, which were used to suggest applications in practice. Further studies are needed to comprehend nephrologists’ and CKD patients’ perspectives on fasting.

The impact of Ramadan fasting on metabolic profile among type 2 diabetes mellitus patients: A meta-analysis

BACKGROUND AND AIMS

Majority of Muslims with type 2 diabetes mellitus (T2DM) fasted during Ramadan regardless of possible risk of complication. This systematic review aims to assess the impact of Ramadan fasting on metabolic profile and hypoglycemia event among T2DM patients.

METHODS

Literature searching was conducted on December 2019 at PUBMED, Medline (EBSCOhost), and ProQuest databases using the following keywords: Ramadan fasting, type 2 diabetes mellitus, glycemic and lipid profile, anthropometry measurements, and hypoglycemia. Observational studies in adults and published in English which analyze the glucose parameters, lipid profile, and hypoglycemia among T2DM patients during Ramadan were included in the analysis. All studies were assessed for its risk of bias using New-Castle Ottawa Scale. The heterogeneity of the studies was analyzed using I² (square) test and the overall mean difference between studied parameters before and after Ramadan fasting was calculated using Weighted Mean Difference (WMD) test using Stata 13.

RESULTS

A total of 28 observational studies that were conducted in Middle Eastern, African, and Asian countries were included. This review found decrease in FPG level by -15.28 (95% CI -17.22, -13.34) mg/dl, HbA1c by -0.27 (95% CI -0.32, -0.22)%, total cholesterol by -12.88 (95% CI -14.68, -11.09) mg/dL, LDL-C by -4.42 (95% CI -6.17, -2.66)mg/dl, HDL-C by -1.09 (95% CI -1.71 - 0.47) mg/dL, triglyceride by -2.47 (95% CI -3.69 - 1.24) mg/dL and decreased anthropometry measurement. No studies reported fatal hypoglycemia event.

CONCLUSIONS

Ramadan fasting resulted in slight improvement of overall metabolic profile and anthropometry among T2DM patients with relatively low incidence of hypoglycemia.

Fasting during Ramadan in people with chronic kidney disease: a review of the literature

Chronic kidney disease (CKD) is common among Muslim patients, and many such patients are keen to fast during the month of Ramadan. Fasting for prolonged periods may be deleterious for patients with CKD, but the changing season of fasting means that the duration of fast is very variable between geographical locations. There is, furthermore, a paucity of evidence to guide patients and clinicians in management of fasting in people with CKD. In this article, we aim to review the available evidence for patients with CKD and fasting, including haemodialysis and renal transplantation. We suggest that all patients with CKD should be deemed high risk or very high risk for fasting. We conclude, however, that patients with stable mild/moderate CKD (stage 1-3) may be able to fast providing they are carefully monitored and counselled. We also suggest that patients with stable renal transplants may also be able to fast, providing they are monitored carefully by their transplant team. Patients on haemodialysis or peritoneal dialysis should not be encouraged to fast, but if they do so, they will need careful weekly monitoring. There is an urgent need for high-quality data for patients with CKD who plan to fast over Ramadan, to enable more guidance to be developed for this vulnerable group of patients.
