Prevalence and Risk Factors of Gastroesophageal Reflux Disease in Patients with Type 2 Diabetes Mellitus

Metabolic effects of bariatric surgery on patients with type 2 diabetes: a population-based study

BACKGROUND

Bariatric surgery among patients with obesity and type 2 diabetes (T2D) can induce complete remission. However, it remains unclear whether sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) has better T2D remission within a population-based daily practice.

OBJECTIVES

To compare patients undergoing RYGB and SG on the extent of T2D remission at the 1-year follow-up.

SETTING

Nationwide, population-based study including all 18 hospitals in the Netherlands providing metabolic and bariatric surgery.

METHODS

Patients undergoing RYGB and SG between October 2015 and October 2018 with 1 year of complete follow-up data were selected from the mandatory nationwide Dutch Audit for Treatment of Obesity (DATO). The primary outcome is T2D remission within 1 year. Secondary outcomes include ≥20% total weight loss (TWL), obesity-related co-morbidity reduction, and postoperative complications with a Clavien-Dindo (CD) grade ≥III within 30 days. We compared T2D remission between RYGB and SG groups using propensity score matching to adjust for confounding by indication.

RESULTS

A total of 5015 patients were identified from the DATO, and 4132 (82.4%) had completed a 1-year follow-up visit. There were 3350 (66.8%) patients with a valid T2D status who were included in the analysis (RYGB = 2623; SG = 727). RYGB patients had a lower body mass index than SG patients, but were more often female, with higher gastroesophageal reflux disease and dyslipidemia rates. After adjusting for these confounders, RYGB patients had increased odds of achieving T2D remission (odds ratio [OR], 1.54; 95% confidence interval [CI], 1.14-2.1; P < .01). Groups were balanced after matching 695 patients in each group. After matching, RYGB patients still had better odds of T2D remission (OR, 1.91; 95% CI, 1.27-2.88; P < .01). Also, significantly more RYGB patients had ≥20%TWL (OR, 2.71; 95% CI, 1.96-3.75; P < .01) and RYGB patients had higher dyslipidemia remission rates (OR, 1.96; 95% CI, 1.39-2.76; P < .01). There were no significant differences in CD ≥III complications.

CONCLUSION

Using population-based data from the Netherlands, this study shows that RYGB leads to better T2D remission rates at the 1-year follow-up and better metabolic outcomes for patients with obesity and T2D undergoing bariatric surgery in daily practice.

The effect of proton pump inhibitors on glycaemic control in diabetic patients

Objective

This study aimed to evaluate the effect of proton pump inhibitors on glycaemic control amongst diabetic patients taking anti-diabetic medications.

Methods

This randomised interventional clinical study was conducted in Basic Medical Sciences Institute, Jinnah Postgraduate Medical Centre, Karachi. Eighty patients of either sex (aged 30–60 years) with type 2 diabetes mellitus and without any known comorbidities were equally divided into two groups (i.e., n = 40 for each group) and were included in this study. Group A received metformin and glimepiride, while Group B, metformin and glimepiride plus omeprazole. The efficacy of the combination medications was evaluated based on fasting blood sugar (FBS) and glycosylated haemoglobin (HbA1c) levels. Serum creatinine and liver function tests were reviewed to evaluate patients' safety profile at the initial visit and after 12 weeks.

Results

After 12 weeks of omeprazole therapy, we observed a more significant improvement in glycaemic control in group B compared to group A based on the patients' FBS (108 ± 2.37 vs. 126 ± 2.9, P = 0.001) and HbA1c levels (7.29 ± 0.07 vs. 7.47 ± 0.04, P = 0.030).

Conclusion

The addition of a proton pump inhibitor along with anti-diabetic medications was considered effective in achieving better glycaemic control.

Prediabetes and gastrointestinal (GI) symptoms; a cross-sectional study

AIMS

Prediabetes associate with known micro and macrovascular complications of diabetes. Also gastrointestinal symptoms are present in diabetics higher than general population. The aim of this study was evaluation of gastrointestinal symptoms in subjects with prediabetes.

METHODS

This analytical cross-sectional study was conducted on 130 persons 30-65 years old, 65 pre-diabetic patients and 65 persons without glucose disorders from 2014 to 2015 in YAZD province. FBS and HbA1c used for diagnosis prediabetes. Demographic and medical history were collected. A questionnaire according to Rome III Criteria was used to collect digestive information (diarrhea, abdominal pain, constipation, abdominal bloating, heartburn, increased gas passing, nausea, intermittent diarrhea and constipation in the last 6 months ago). Frequency of GI symptoms in subjects with and without glucose disorders were compared. Data were analyzed by SPSS software Version 20. Data were reported as mean ± standard deviation or frequency and T-test, Chi Square and Spearman correlation coefficient tests were used. P-value less than 0.05 were considered statistically significant.

RESULTS

Higher frequency of bloating, early satiety, nausea, heartburn, gas passing and constipation are seen in the pre-diabetes group than in the control group; (p-value 0.0001, 0.0001, 0.0001, 0.0001, 0.001 and 0.0001 respectively). 96.9% in prediabetics had at least one gastrointestinal symptom, while in the normal groups 50% had at least one GI symptom (p-value: 0.0001).

CONCLUSIONS

Gastrointestinal symptoms were seen in prediabetics higher than healthy persons. So, prediabetes can not be considered an entirely benign and asymptomatic condition. Lifestyle interventions maybe necessary at this state.

Gastrointestinal Symptoms in Diabetes: Prevalence, Assessment, Pathogenesis, and Management

If you haven't measured something, you really don't know much about it.-Karl Pearson (attributed)Gastrointestinal (GI) symptoms represent an important and often unappreciated cause of morbidity in diabetes, although the significance of this burden across the spectrum of patients and the underlying pathophysiology, including the relationship of symptoms with glycemic control, remain poorly defined. The relevance of GI symptoms and the necessity for their accurate assessment have increased with the greater focus on the gut as a therapeutic target for glucose lowering. This review addresses the prevalence, assessment, pathogenesis, and management of GI symptoms in diabetes, beginning with broad principles and then focusing on specific segments of the GI tract. We initially performed a literature search of PubMed by using synonyms and combinations of the following search terms: "gastrointestinal symptoms", "diabetes", "prevalence", "pathogenesis", "diagnosis", and "management". We restricted the search results to English only. Review papers and meta-analyses are presented as the highest level of evidence where possible followed by randomized controlled trials, uncontrolled trials, retrospective and observational data, and expert opinion.

Risk of GERD with Diabetes Mellitus, Hypertension and Bronchial Asthma - A Hospital based Retrospective Cohort Study

INTRODUCTION

The rise in Gastro-Esophageal Reflux Disease (GERD) prevalence appears to have coincided with a simultaneous increase in the prevalence of diabetes mellitus, hypertension and bronchial asthma amongst the Indian population. Despite being evaluated extensively for their role as a risk factor for GERD, till date this relationship has remained a debatable one. Moreover, literature available on such studies conducted within Indian population remains scarce.

AIM

The aim of the present study was to examine the risk of developing GERD in patients suffering from diabetes mellitus, hypertension and asthma in a Southern Indian population. The present retrospective, triple cohort and hospital based study was conducted by accessing the patient records from the medical records department of a tertiary care hospital in Southern India.

MATERIALS AND METHODS

The patient's records were accessed from the year 2011 onwards. Relative Risk (RR) was calculated to determine the risk of development of GERD with every disease. Chi-square test was used to determine the statistical significance of the relationship between each disease and the development of GERD. A p-value of <0.05 was considered statistically significant.

RESULTS

In view of the time constraints as well as the limitations of the inclusion and exclusion criteria, data pertaining to only 40, 71 and 53 patients in Cohort 1 (diabetics), 2 (hypertensives) and 3 (bronchial asthmatics) respectively could be analyzed in the present study. The relative risk of GERD development was greater than 1 for patients belonging to Cohort 2 and 3, suggesting that the risk of GERD development is higher amongst hypertensives and asthmatics. Surprisingly, the diabetics (Cohort 1) were not associated with a high risk of GERD development. However, the relationship between any of the disease and GERD development was not statistically significant.

CONCLUSION

The present study found an increased risk of GERD development amongst patients suffering from hypertension and bronchial asthma, but not with diabetes mellitus.

Prevalence and Correlates of Gastroesophageal Reflux Disease in Southern Iran: Pars Cohort Study

BACKGROUND

Prevalence of gastroesophageal reflux disease (GERD) is increasing worldwide. We aimed to estimate the prevalence of GERD in Pars Cohort Study (PCS) and to find its correlates.

METHODS

We used the baseline data from PCS. PCS was conducted in the district of Valashahr in Fars province in southern Iran from 2012 to 2014. 9264 inhabitants who were 40-75 years old, and agreed to participate were enrolled. Data were collected by a structured questionnaire and simple physical examination of all participants.

RESULTS

Generally, 58.50% (95% CI 57.49 - 59.51) of the participants had GERD and 25.10% (95% CI 24.22 - 25.99) experienced it at least weekly. Approximately, 32.0%, 52.0%, and 24.4% of the participants reported heart burn sensation, regurgitation, and both symptoms, respectively. Being female (OR: 1.45, 95% CI 1.27 - 1.65), being older (OR: 1.20, 95% CI 1.06 - 1.36), being divorced/ widowed/separated (OR: 1.38, 95% CI 1.01 - 1.91), and lower education (OR: 1.43, 95% CI 1.02 - 2.03) were associated with frequent GERD.

CONCLUSION

GERD is common in PCS and its prevalence is close to that in western countries. Being female, higher age, being divorced/widowed/separated, lower education, history of hypertension, anxiety, insomnia, and non-cigarette tobacco smoking were associated with frequent GERD. We are going to investigate the causal relationship between these risk factors and GERD in the next stages of PCS.
