Insulin Inertia Among People With Type 2 Diabetes Mellitus in Qatar: The INERT-Q Study.

BACKGROUND: Achieving and maintaining adequate glycaemic control is critical to reduce diabetes-related complications. Therapeutic inertia is one of the leading causes of suboptimal glycaemic control. AIM: To assess the degree of inertia in insulin initiation and intensification in people with Type 2 diabetes mellitus (DM-2). METHODS: We performed a retrospective longitudinal cohort study and followed DM-2 2 years before and 2 years after the start of insulin. The primary outcome was the proportion of patients who achieved glycaemic targets (HBA1c ≤ 7.5%) at 6th month, 1st year and 2nd year. RESULTS: We included 374 predominantly male subjects (62%). The mean age was 55.3 ± 11.3 years, the mean duration of DM-2 was 12.0 ± 7.3 years, 64.4% were obese, 47.6% had a microvascular disease, and 24.3% had a macrovascular disease. The mean HBA1c at -2nd year and -1st year was 9.2 ± 2.1% and 9.3 ± 2.0%, respectively. The mean HbA1C at the time of insulin initiation was 10.4 ± 2.1%. The mean HBA1c at 6th month, 12th month and 2nd year was 8.5 ± 1.8%, 8.4 ± 1.8% and 8.5 ± 1.7%, respectively. The proportion of subjects who achieved HBA1c targets at 6th month, 12th month and 2nd year was 32.9%, 31.0% and 32.9%, respectively. Multivariate logistic regression analysis showed that achieving HBA1c targets at 6th month and 1st year increases the odds of achieving HBA1c targets at 2nd year (OR 4.87 [2.4-9.6] p < 0.001) and (OR 6.2 [3.2-12.0], p < 0.001), respectively. CONCLUSION: In people with DM-2, there was an alarming delay in starting and titrating insulin. The reduction in HBA1c plateaued at 6th month. Earlier initiation and intensification of insulin therapy are critical to achieving glycaemic targets. More studies are needed to examine the causes of therapeutic inertia from physicians', patients' and systems' points of view.

Hypergonadotropic hypogonadism and chromosomal aberrations: clinical heterogeneity and implications on the health of elderly men, case series.

BACKGROUND: Hypogonadism in older men is often considered as late onset hypogonadism. However, this clinical condition results from primary testicular failure which could be of genetic origin with Klinefelter syndrome being the most common chromosomal abnormality associated with it. CASE PRESENTATION: We report a heterogeneous group of cases who were diagnosed with hypergonadotropic hypogonadism in their adulthood and were found to have rare chromosomal aberrations. All were elderly men (in their 70 s and 80 s) for whom the diagnosis was made during the evaluation of incidental symptoms suggestive of endocrinopathy. The first had hyponatremia; the other two had gynaecomastia and features of hypogonadism noted during admission for various acute medical problems. With respect to their genetic results; the first had a male karyotype with balanced reciprocal translocation between the long arm of chromosome 4 and the short arm of chromosome 7. The second case had a male karotype with one normal X chromosome and an isochrome for the short arm of the Y chromosome. The third case was an XX male with unbalanced translocation between the X & Y chromosomes with retention of the SRY locus. CONCLUSION: Hypergonadotrophic hypogonadism in the elderly, may be due to chromosomal aberrations, resulting in heterogeneous and diverse clinical phenotypes. Vigilance must be exercised when seeing cases with subtle clinical findings. This report suggests that in selected cases of adult hypergonadotropic hypogonadism, chromosomal analysis may be indicated.

Bimodal distribution of thyroid dysfunction triggered by COVID-19 Infection: An experience from a single endocrine center-a case series and literature review.

BACKGROUND: COVID-19 infection has been spreading across the globe since the end of 2019, and it continues to cause chronic multi-system sequelae, of which thyroid dysfunction appears to be the major one. We have discussed here 10 cases of thyroid dysfunction after COVID-19 infection. METHODS: Case series report. From October 2020 to July 2021, a series of 10 cases of thyroid dysfunction after COVID-19 infection were recorded and managed in a single outpatient endocrine center in Doha, Qatar. CASES PRESENTATION: We have reported 5 cases of Graves's hyperthyroidism, 2 of chronic primary hypothyroidism (including one with Grave's disease [GD]) who was treated through radioactive iodine (RAI) therapy, one case of subacute thyroiditis, one case with "Sick euthyroid disease," and one case of central hypothyroidism. Presently, patients with GD are being treated with carbimazole and those with hypothyroidism are being treated with levothyroxine. The remaining patients had recovered with euthyroid. CONCLUSION: This is the largest case series reported from a single center to date. The findings of this series indicate a bimodal distribution of thyroid dysfunction in patients with COVID-19 infection. A review of the literature and discussion of potential pathophysiological mechanisms has been presented. We have emphasized the importance of screening for thyroid dysfunction in "post-COVID-19" cases, considering that the prevalence may be underestimated.

Management of Diabetes and Hypertension within the Gulf Region: Updates on Treatment Practices and Therapies.

Cardiovascular disease (CVD) is a leading cause of death globally, driven by the high rates of risk factors, such as diabetes and hypertension. As the prevalence of these risk factors is particularly high in the Gulf region, better diagnosis and management of type 2 diabetes (T2D) and hypertension has the potential to dramatically reduce adverse cardiovascular outcomes for individuals in that part of the world. This article provides a summary of presentations made during the EVIDENT summit, a virtual symposium on Evidence in Diabetes and Hypertension, held in September 2021, including a review of the various guidelines for both T2D and hypertension, as well as recent findings relevant to the safety and efficacy for therapies relating to these conditions. Of relevance to the Gulf region, the risk of hypoglycaemia with sulfonylureas during Ramadan was reviewed. For the management of T2D, sulfonylureas have been a long-standing medication used to achieve glycaemic control; however, differences have emerged between early and later generations, with recent studies suggesting improvements in the safety profiles of late-generation sulfonylureas. For patients with hypertension, incremental therapy changes are recommended to reduce the risk of cardiovascular complications that are associated with increasing blood pressure. For first-line therapy, angiotensin-converting enzyme inhibitors (ACEi), such as perindopril, have been demonstrated to reduce the risk of cardiovascular and all-cause mortality. The addition of calcium channel blockers and diuretics to ACEi has been shown to be effective in patients with poorly controlled hypertension. The different renin-angiotensin-aldosterone system inhibitors are reviewed, and the benefit of combination therapies, including amlodipine and indapamide in patients with difficult-to-control hypertension, is investigated. The benefits of lifestyle modifications for these patients are also discussed, with important clinical considerations that are expected to inform patient management in daily clinical practice.

Prevalence and risk factors for diabetic peripheral neuropathy, neuropathic pain and foot ulceration in the Arabian Gulf region.

AIMS/INTRODUCTION: This study determined the prevalence and risk factors for diabetic peripheral neuropathy (DPN), painful DPN and diabetic foot ulceration (DFU) in patients with type 2 diabetes in secondary healthcare in Qatar, Kuwait and the Kingdom of Saudi Arabia. MATERIALS AND METHODS: Adults aged 18-85 years with type 2 diabetes were randomly enrolled from secondary healthcare, and underwent clinical and metabolic assessment. DPN was evaluated using vibration perception threshold and neuropathic symptoms and painful Diabetic Peripheral Neuropathy was evaluated using the Douleur Neuropathique 4 questionnaire. RESULTS: A total of 3,021 individuals were recruited between June 2017 and May 2019. The prevalence of DPN was 33.3%, of whom 52.2% were at risk of DFU and 53.6% were undiagnosed. The prevalence of painful DPN was 43.3%, of whom 54.3% were undiagnosed. DFU was present in 2.9%. The adjusted odds ratios for DPN and painful DPN were higher with increasing diabetes duration, obesity, poor glycemic control and hyperlipidemia, and lower with greater physical activity. The adjusted odds ratio for DFU was higher with the presence of DPN, severe loss of vibration perception, hypertension and vitamin D deficiency. CONCLUSIONS: This is the largest study to date from the Middle East showing a high prevalence of undiagnosed DPN, painful DPN and those at risk of DFU in patients with type 2 diabetes, and identifies their respective risk factors.

Safety and Effectiveness of Insulin Glargine 300 U/mL in Participants with Type 2 Diabetes Who Fast During Ramadan in The Gulf Region: A Subgroup Analysis of the Real-World ORION Study.

INTRODUCTION: To evaluate the safety and effectiveness of insulin glargine 300 U/mL (Gla-300) in people with type 2 diabetes mellitus (T2DM) in the Gulf region who fast during Ramadan. METHODS: ORION was a real-world, prospective, observational study in people with T2DM treated with Gla-300 during pre-Ramadan, Ramadan, and post-Ramadan periods. This subgroup analysis included 222 participants from the Gulf region (Kuwait, Saudi Arabia, United Arab Emirates, and Qatar). The primary endpoint was the percentage of participants experiencing severe and/or symptomatic documented hypoglycemia (self-monitored plasma glucose [SMPG] ≤ 70 mg/dL) during Ramadan. Changes in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), SMPG, body weight, insulin dose, and adverse events (AEs) were also evaluated. RESULTS: The primary endpoint was reported in one (0.5%) participant during Ramadan. The incidence rate of symptomatic documented hypoglycemia (SMPG ≤ 70 mg/dL) decreased from the pre-Ramadan (3.2%) to Ramadan period (0.5%), and no severe hypoglycemia events were reported during the study. Reductions were observed in HbA1c (mean ± standard deviation: - 0.51 ± 0.95% [- 5.5 ± 10.4 mmol/mol]), FPG (- 13.9 ± 47.5 mg/dL), and SMPG (- 6.1 ± 27.1 mg/dL). No significant changes were observed in body weight or Gla-300 dose. AEs were reported in 11 (5.0%) participants. CONCLUSION: In a real-world setting in the Gulf region, Gla-300 treatment in people with T2DM during Ramadan was associated with a low incidence of hypoglycemia and improved glycemic control. TRIAL REGISTRATION: CTRI/2019/02/017636.

Diabetes and Ramadan: Practical guidelines 2021.

Fasting during Ramadan is one of the five pillars of Islam and is obligatory for all healthy Muslims from the age of puberty. Though individuals with some illness and serious medical conditions, including some people with diabetes, can be exempted from fasting, many will fast anyway. It is of paramount importance that people with diabetes that fast are given the appropriate guidance and receive proper care. The International Diabetes Federation (IDF) and Diabetes and Ramadan (DaR) International Alliance have come together to provide a substantial update to the previous guidelines. This update includes key information on fasting during Ramadan with type 1 diabetes, the management of diabetes in people of elderly ages and pregnant women, the effects of Ramadan on one's mental wellbeing, changes to the risk of macrovascular and microvascular complications, and areas of future research. The IDF-DAR Diabetes and Ramadan Practical Guidelines 2021 seek to improve upon the awareness, knowledge and management of diabetes during Ramadan, and to provide real-world recommendations to health professionals and the people with diabetes who choose to fast.

Successful use of the sodium-glucose co-transporter-2 inhibitor dapagliflozin in patients with renal transplant and diabetes: a case series and literature review.

Management of patients with diabetes and renal transplant could be challenging. Transplant patients use multiple immune suppressants that can worsen or even trigger hyperglycemia. There are no data about the use of the new class of sodium-glucose co-transporter-2 (SGLT-2) inhibitor dapagliflozin in patients with renal transplant and diabetes. CASE SERIES: Four patients, with diabetes, who are attending the diabetes clinic at our institution, are presented here. They were all counseled to be started on dapagliflozin 10 mg to improve diabetes control as they were on multiple agents and not achieving targets. All four patients showed significant improvement in hemoglobin A1c, with no adverse effects on renal parameters and had favorable effect on weight and blood pressure (BP). CONCLUSION: Use of the SGLT-2 inhibitor dapagliflozin in the standard dose of 10 mg helped to achieve satisfactory control with favorable effects on BP and weight with no adverse effects on renal function.

A tale of many tumors and one endocrine site: A case series of pituitary metastases.

BACKGROUND: Metastases to the pituitary gland are extremely rare with an incidence rate reported from an autopsy series of 1.8%-12%, and only 20% was diagnosed clinically. Tumors that commonly metastasize are breast and lung tumors. CASE SERIES: We present a series of five cases, including four female patients and one male patient with metastatic cancer. Two women had metastatic small lung cancer and presented with diabetes insipidus (DI). Two women had metastatic breast cancer, of which one presented with DI and the other with panhypopituitarism. The male patient had bronchogenic adenocarcinoma and presented with DI. CONCLUSION: Our case series confirmed earlier reports that DI is the most common presentation of metastases to the pituitary gland.

Optimal glycaemic and blood pressure but not lipid targets are related to a lower prevalence of diabetic microvascular complications.

BACKGROUND: Diabetic microvascular complications are a major cause of morbidity and are related to glycaemic control and cardiovascular risk factors. AIMS: We sought to determine the association of microvascular complications in relation to control of glycemia, blood pressure and lipids in T2DM patients attending secondary care in Qatar. METHODS: This is a cross-sectional study undertaken in patients with T2DM attending Qatar's National Diabetes Centres. Patients underwent assessment of glycemia, blood pressure and lipids and prevalence of diabetic peripheral neuropathy (DPN), retinopathy and microalbuminuria. RESULTS: We included 1114 subjects aged 52.1 ± 11.3 years with a duration of diabetes 10.0 ± 7.6 years and had a prevalence of 25.8% for DPN, 34.3% for painful DPN, 36.8% for microalbuminuria and 25.1% for retinopathy. Patients who achieved an HbA1c ≤ 7.0% compared to >7% had a significantly lower prevalence of DPN (P < 0.01), painful DPN (P < 0.01), retinopathy (P < 0.01) and microalbuminuria (P < 0.007). Patients who achieved a systolic BP ≤ 140 mmHg compared to >140 mmHg had a significantly lower prevalence of DPN (P < 0.001), painful DPN (P < 0.001), retinopathy (P < 0.001) and microalbuminuria (P < 0.001). Patients who achieved an LDL ≤2.6 mmol/l compared to >2.6 mmol/l had a significantly higher prevalence of DPN (P < 0.03), but no difference in other outcomes. There was no difference in microvascular complications between those who achieved a HDL-C ≥ 1.02 mmol/l, and among those who achieved triglycerides ≤1.7 mmol/l. CONCLUSIONS: Optimal control of glycemia and blood pressure, but not lipids is associated with a lower prevalence of diabetic microvascular complications.

Carbimazole-Induced Jaundice in Thyrotoxicosis: A Case Report.

Carbimazole is a commonly used antithyroid drug in thyrotoxicosis. It is generally well tolerated, and its side effects include allergic skin reactions, gastrointestinal upset, agranulocytosis, and hepatotoxicity. Hepatitis is a rare but serious side effect. Here we report a case of carbimazole-induced hepatitis with severe cholestasis that was managed by switching to propylthiouracil. Most of the literature recommends radioiodine or surgery as the definitive treatment for hyperthyroidism in thionamide-induced hepatitis rather than switching to other thionamide. However, substitution of one thionamide for another can be tried as we did in this case, without any increased risk of hepatotoxicity as the mechanism of liver injury differs in both groups. A previously healthy 30-year-old lady who was diagnosed with thyrotoxicosis one month earlier that was treated with carbimazole 60 mg daily was admitted to the medical ward with yellowish discoloration of sclera, urine, and pruritus of one-week duration. Systemic examination was unremarkable except for icterus. Investigation showed hyperbilirubinemia and elevated liver enzymes. A probable diagnosis of carbimazole-induced cholestatic hepatitis was made and the drug was discontinued. Other causes of hepatitis and cholestasis were excluded. Attempts to arrange radioiodine or treat the patient surgically were not successful. She was continued on propranolol and later started on steroids and propylthiouracil. The patient's liver function tests (LFTs) started improving gradually. On follow-up, LFTs normalized at four weeks and thyroid function tests (TFTs) showed signs of improvement. The patient was followed up for six months after discharge and was doing well clinically on follow-up; her repeat TFT and LFT were completely normal. Carbimazole-induced hepatitis is exceedingly rare; however, it should be considered in patients with jaundice and thyrotoxicosis. Despite reports of cross-reactivity of the two available antithyroid drugs, switching from carbimazole to propylthiouracil and steroid therapy may be an option if other options of definitive therapy could not be arranged or are contraindicated.

Mitigation of hypoglycemia during Ramadan using the flash glucose monitoring system following dose adjustment of insulin and sulphonylurea in patients taking multiple glucose-lowering therapies (The PROFAST-IT Study).

BACKGROUND AND HYPOTHESIS: Patients with type-2 diabetes mellitus (T2DM) on multiple glucose-lowering therapies who fast during Ramadan are at increased risk of hypoglycemia. We have assessed the utility of the flash glucose monitoring system after adjusting the dose of insulin and sulphonylureas to mitigate the risk of hypoglycemia in patients with T2DM who fast during Ramadan. PATIENTS AND METHODS: Patients with T2DM on either basal insulin or a sulphonylurea and at least 2 other glucose-lowering agents received structured education and adjustment of insulin or sulphonylurea dose according to the PROFAST Ramadan protocol. Glucose variability and episodes of hypoglycemia were assessed using the flash glucose monitoring system (Free Style Libre) before and during Ramadan. RESULTS: A total of 33 patients with T2DM (on sulphonylurea (SU+) (n = 21), on basal insulin (BI+) (n = 12) aged 50.8 ± 1.6 years with a diabetes duration of 13.1 ± 6.5 years were studied. The average sensor glucose was 154 ± 34 mg/dl (8.5 ± 1.88 mmol/l) with 65.2% in the target range before Ramadan and the average sensor glucose was 156 ± 36 mg/dl (8.6 ± 2.0 mmol/l) with 67.1% in the target range during Ramadan. The incidence of hypoglycemia in the whole group (2.9 v 2.9) and in the SU+ (3.7 vs 3.0) and BI+ (1.7 vs 2.9) groups and eHbA1c (P = 0.56, P = 0.93), average glucose (P = 0.56, P = 0.92) and time within range (P = 0.63, P = 0.73) did not change in the SU+ and BI+ groups, respectively, before and during Ramadan. CONCLUSION: Structured education with adjustment of the dose of glucose lowering medication alongside use of the FGMS can effectively mitigate the increased risk of hypoglycemia in patients with T2DM on multiple glucose-lowering therapies who fast during Ramadan.

Prevalence and risk factors for diabetic neuropathy and painful diabetic neuropathy in primary and secondary healthcare in Qatar.

AIMS/INTRODUCTION: This study determined the prevalence and risk factors for diabetic peripheral neuropathy (DPN) and painful DPN (pDPN) in patients with type 2 diabetes in primary healthcare (PHC) and secondary healthcare (SHC) in Qatar. MATERIALS AND METHODS: This was a cross-sectional multicenter study. Adults with type 2 diabetes were randomly enrolled from four PHC centers and two diabetes centers in SHC in Qatar. Participants underwent assessment of clinical and metabolic parameters, DPN and pDPN. RESULTS: A total of 1,386 individuals with type 2 diabetes (297 from PHC and 1,089 from SHC) were recruited. The prevalence of DPN (14.8% vs 23.9%, P = 0.001) and pDPN (18.1% vs 37.5%, P < 0.0001) was significantly lower in PHC compared with SHC, whereas those with DPN at high risk for diabetic foot ulceration (31.8% vs 40.0%, P = 0.3) was comparable. The prevalence of undiagnosed DPN (79.5% vs 82.3%, P = 0.66) was comparably high, but undiagnosed pDPN (24.1% vs 71.5%, P < 0.0001) was lower in PHC compared with SHC. The odds of DPN and pDPN increased with age and diabetes duration, and DPN increased with poor glycemic control, hyperlipidemia and hypertension, whereas pDPN increased with obesity and reduced physical activity. CONCLUSIONS: The prevalence of DPN and pDPN in type 2 diabetes is lower in PHC compared with SHC, and is attributed to overall better control of risk factors and referral bias due to patients with poorly managed complications being referred to SHC. However, approximately 80% of patients had not been previously diagnosed with DPN in PHC and SHC. Furthermore, we identified a number of modifiable risk factors for PDN and pDPN.

Artificial Intelligence (AI) based machine learning models predict glucose variability and hypoglycaemia risk in patients with type 2 diabetes on a multiple drug regimen who fast during ramadan (The PROFAST - IT Ramadan study).

OBJECTIVE: To develop a machine-based algorithm from clinical and demographic data, physical activity and glucose variability to predict hyperglycaemic and hypoglycaemic excursions in patients with type 2 diabetes on multiple glucose lowering therapies who fast during Ramadan. PATIENTS AND METHODS: Thirteen patients (10 males and three females) with type 2 diabetes on 3 or more anti-diabetic medications were studied with a Fitbit-2 pedometer device and Freestyle Libre (Abbott Diagnostics) 2 weeks before and 2 weeks during Ramadan. Several machine learning techniques were trained to predict blood glucose levels in a regression framework utilising physical activity and contemporaneous blood glucose levels, comparing Ramadan to non-Ramadan days. RESULTS: The median age of participants was 51 years (IQR 49-52); median BMI was 33.2 kg/m2 (IQR 33.0-35.9) and median HbA1c was 7.3% (IQR 6.7-7.8). The optimal model using physical activity achieved an R2 of 0.548 and a mean absolute error (MAE) of 30.30. The addition of electronic health record (ehr) information increased R2 to 0.636 and reduced MAE to 26.89 and the time of the day feature further increased R2 to 0.768 and reduced MAE to 20.55. Combining all the features together resulted in an optimal XGBoost model with an R2 of 0.836 and MAE of 17.47. This model accurately estimated normal glucose levels in 2584/2715 (95.2%) readings and hyperglycaemic events in 852/1031 (82.6%) readings, but fewer hypoglycaemic events (48/172 (27.9%)). The optimal XGBoost model prioritized age, gender, BMI and HbA1c followed by glucose levels and physical activity. Interestingly, the blood glucose level prediction by our model was influenced by use of SGLT2i. CONCLUSION: XGBoost, a machine learning AI algorithm achieves high predictive performance for normal and hyperglycaemic excursions, but has limited predictive value for hypoglycaemia in patients on multiple therapies who fast during Ramadan.

Diagnosis and management of vitamin D deficiency in the Gulf Cooperative Council (GCC) countries: an expert consensus summary statement from the GCC vitamin D advisory board.

OBJECTIVE: A summary of recommendations is given within the Gulf Cooperation Council (GCC) setting on the assessment and management of vitamin D deficiency in the region. METHODS: An assembly of 11 regional experts gathered to formulate an all-inclusive approach to vitamin D deficiency within GCC. RESULTS AND CONCLUSION: Several gaps were identified before regional guidelines could be developed. These include adequacy and standardization of vitamin D testing, frequency of repeated testing and reference ranges, distinguishing prevention from the treatment of vitamin D deficiency, quality assurance of vitamin D products sold within GCC including contents and origins of products, and cut-points for vitamin D levels in local populations. A platform is created that can be further developed for overall regional implementation.

Prevalence and management of diabetic neuropathy in secondary care in Qatar.

AIMS: Diabetic neuropathy (DN) is a "Cinderella" complication, particularly in the Middle East. A high prevalence of undiagnosed DN and those at risk of diabetic foot ulceration (DFU) is a major concern. We have determined the prevalence of DN and its risk factors, DFU, and those at risk of DFU in patients with type 2 diabetes mellitus (T2DM) in secondary care in Qatar. MATERIALS AND METHODS: Adults with T2DM were randomly selected from the two National Diabetes Centers in Qatar. DN was defined by the presence of neuropathic symptoms and a vibration perception threshold (VPT) ≥ 15 V. Participants with a VPT ≥ 25 V were categorized as high risk for DFU. Painful DN was defined by a DN4 score ≥4. Logistic regression analysis was used to identify predictors of DN. RESULTS: In 1082 adults with T2DM (age 54 ± 11 years, duration of diabetes 10.0 ± 7.7 years, 60.6% males), the prevalence of DN was 23.0% (95% CI, 20.5%-25.5%) of whom 33.7% (95% CI, 27.9%-39.6%) were at high risk of DFU, and 6.3% had DFU; 82.0% of the patients with DN were previously undiagnosed. The prevalence of DN increased with age and duration of diabetes and was associated with poor glycaemic control (HbA1c ≥ 9%) AOR = 2.1 (95% CI, 1.3-3.2), hyperlipidaemia AOR = 2.7 (95% CI, 1.5-5.0), and hypertension AOR = 2.0 (95% CI, 1.2-3.4). CONCLUSIONS: Despite DN affecting 23% of adults with T2DM, 82% had not been previously diagnosed with one-third at high risk for DFU. This argues for annual screening and identification of patients with DN. Furthermore, we identify hyperglycaemia, hyperlipidaemia, and hypertension as predictors of DN.

Differential effects of gender and patient background diversity on the changes in metabolic and biophysical profiles in people with type-2 diabetes from different ethnicities who fast during Ramadan (H1439); a prospective study from Qatar.

OBJECTIVE: The 'PROspective Study of dose adjustment of multiple anti-diabetic therapy for Type-2 diabetic patients FASTing the Month of Ramadan aimed to assess the biophysical and metabolic effects of fasting during Ramadan, including HbA1c, weight, blood pressure and lipid profile. STUDY DESIGN METHODS: We performed a prospective study of people with Type-2 diabetes who were on ≥3 drugs for lowering glucose before and after Ramadan of H1438 (May-June 2017) in Hamad Medical Corporation, Qatar. We enrolled 228 participants, of whom 181 completed the study and were included in the analysis. RESULTS: There were 115 (63.5%) men and 66 (36.5%) women, mean age 53.6 ±â€¯9.7 years and mean diabetes duration of 10 ±â€¯6 years. Both HBA1c [7.8% (62 mmol/mol) vs. 7.6% (60 mmol/mol); p = 0.004]; and diastolic BP (75.7 ±â€¯8.55 vs. 68.8 ±â€¯23.1 mmHg, P = 0.001) improved significantly after Ramadan while there was an increase in total cholesterol (3.94 ±â€¯0.89 mmol/l vs 4.11 ±â€¯1.02 mmol/l; p = 0.008) and triglycerides (1.55 ±â€¯0.72 mmol/l vs 1.71 ±â€¯0.9 mmol/l; p = 0.012). Subgroup analysis showed that patients on sulphonylurea, South Asians and males had a significant reduction in both HBA1c and weight. CONCLUSION: Patients with Type 2 diabetes who fast during Ramadan show an improvement in glycaemic control and diastolic blood pressure, but a worsening of total cholesterol and triglycerides, particularly those of South Asian origin and men.

Prevalence and risk factors for painful diabetic neuropathy in secondary healthcare in Qatar.

AIMS/INTRODUCTION: Painful diabetic peripheral neuropathy (PDPN) has a significant impact on the patient's quality of life. The prevalence of PDPN in the Middle East and North Africa region has been reported to be almost double that of populations in the UK. We sought to determine the prevalence of PDPN and its associated factors in type 2 diabetes mellitus patients attending secondary care in Qatar. MATERIALS AND METHODS: This was a cross-sectional study of 1,095 participants with type 2 diabetes mellitus attending Qatar's two national diabetes centers. PDPN and impaired vibration perception on the pulp of the large toes were assessed using the Douleur Neuropathique en 4 questionnaire with a cut-off ≥4 and the neurothesiometer with a cut-off ≥15 V, respectively. RESULTS: The prevalence of PDPN was 34.5% (95% confidence interval [CI] 31.7-37.3), but 80% of these patients had not previously been diagnosed or treated for this condition. Arabs had a higher prevalence of PDPN compared with South Asians (P < 0.05). PDPN was associated with impaired vibration perception adjusted odds ratio (AOR) 4.42 (95% CI 2.92-6.70), smoking AOR 2.43 (95% CI 1.43-4.15), obesity AOR 1.74 (95% CI 1.13-2.66), being female AOR 1.65 (95% CI: 1.03-2.64) and duration of diabetes AOR 1.08 (95% CI 1.05-1.11). Age, poor glycemic control, hypertension, physical activity and proteinuria showed no association with PDPN. CONCLUSIONS: PDPN occurs in one-third of type 2 diabetes mellitus patients attending secondary care in Qatar, but the majority have not been diagnosed. Arabs are at higher risk for PDPN. Impaired vibration perception, obesity and smoking are associated with PDPN in Qatar.

Metformin or insulin: logical treatment in women with gestational diabetes in the Middle East, our experience.

OBJECTIVE: The debate still continues about the preferred modality of treatment of gestational diabetes requiring pharmacological treatment. Insulin was previously considered as the gold standard, but the National Institute of Health and Care Excellence now recommend metformin as the first line drug of choice. The pharmacological management of gestational diabetes mellitus in the Middle East with its high risk population has not been widely published. We aim to evaluate the safety and efficacy of using metformin in comparison to insulin, in our group of patients, and to study key associated morbidities. RESULTS: A total of 291 women registered in the clinic during the study period. One hundred and twenty-one (121) were women with gestational diabetes Mellitus requiring medical therapy. Among them, 107 delivered at term. Ninety (84%) women received metformin. Additional insulin was required in 32% of these patients. There was a significant difference in the birth weight of babies in the metformin with insulin group of 207 g (p value 0.04) in favour of metformin. There was no significant difference in maternal or neonatal morbidities between the groups. Metformin was thus found to be a safe, practical and cost effective medication to be offered to our population.

Metformin Use Is Not Associated With B12 Deficiency or Neuropathy in Patients With Type 2 Diabetes Mellitus in Qatar.

BACKGROUND: Metformin may lead to B12 deficiency and neuropathy. There are no published data on the prevalence of Metformin-related B12 deficiency and neuropathy in the Arabian Gulf. AIMS: Determine whether Metformin intake is associated with B12 deficiency and whether B12 deficiency is associated with diabetic peripheral neuropathy (DPN) and painful diabetic neuropathy. METHODS: Patients with type 2 diabetes mellitus (T2DM) (n = 362) attending outpatient clinics at HMC underwent assessment of B12 levels, the DN4 questionnaire, and vibration perception threshold (VPT). RESULTS: Comparing Metformin to non-Metformin users there were no differences in B12 levels, VPT, or DN4. The prevalence of B12 deficiency (B12 <133 pmol/l) was lower (P < 0.01) in Metformin (8%) compared to non-Metformin (19%) users. Patients with B12 deficiency had a comparable prevalence and severity of sensory neuropathy and painful neuropathy to patients without B12 deficiency. CONCLUSION: Serum B12 levels were comparable between Metformin and non-Metformin users with T2DM in Qatar. T2DM patients on Metformin had a lower prevalence of B12 deficiency. Furthermore, the prevalence and severity of neuropathy and painful diabetic neuropathy were comparable between patients with and without B12 deficiency.
