Gestational diabetes mellitus as a risk factor for future Type-2 diabetes mellitus: An experience from a tertiary care diabetes hospital, Karachi - Pakistan.

Objective: To evaluate the history of gestational diabetes mellitus and other risk factors in women presenting with Type-2 diabetes mellitus at a tertiary care hospital. Methods: This cross-sectional study was carried out at Baqai Institute of Diabetology & Endocrinology (BIDE), Baqai Medical University (BMU), Karachi-Pakistan from July 2019 to May 2022. Women with Type-2 diabetes mellitus (T2DM) visiting outpatient department of BIDE with a previous history of GDM were recruited. Details were obtained on pre-designed questionnaire after taking informed written consent. Results: A total of 378 women who had a prior history of GDM were included. Mean age (years) was 43.53±10.17. Mostly women were obese (BMI = 30.53±6.08) and have sedentary lifestyle. Mean HbA1c (%) was 9.08±2.24. This study found family history of T2DM and hypertension were common risk factors in women with GDM history. Mostly, women were diagnosed as GDM during 2nd trimester 153(42%) and was mainly seen in multiparous women (occur in 4th and above pregnancy). We found hypertension as common complication during pregnancy. Around 46% women developed T2DM within one year of GDM diagnosis, and 29.6% between one to five years. Conclusion: Majority of women with GDM developed T2DM within five years of diagnosis. The potential associated risk factors were age, family history of diabetes, insulin use during pregnancy, trimester of GDM diagnosis, and hypertension during pregnancy. Awareness and life style modifications along with regular post-partum follow up with screening for T2DM should be part of GDM management to prevent or delay the occurrence of this serious complication.

Change in pulmonary function tests and their relation to the serum levels of ceruloplasmin, copper and superoxide dismutase in patients suffering from Type-1 and Type-2 diabetes.

Objective: To correlate the serum levels of ceruloplasmin (Cp), copper (Cu), and superoxide dismutase (SOD) with pulmonary function tests (PFTs) in non-diabetics (controls) and patients suffering from Type-1 and Type- 2 diabetes. Methods: The comparative cross-sectional study of 348 participants was performed at the Baqai Institute of Diabetes and Endocrinology (BIDE) - Karachi, Pakistan, from February 2019 to September 2020. Individuals having diabetes-related complications, asthma, chronic obstructive pulmonary disease, chest infection, pregnant women and smokers were excluded. A total of 348 participants were included into three groups after signing informed consent. The control group had 107 non-diabetic participants, with an age range of 6 to 60 years. The diagnosed T1D group (n=107) had an age range of 6 to 25 years. While diagnosed T2D group (n=134) had an age range of 26 to 60 years. During the fasting state, anthropometric parameters, blood pressure, spirometry, and a venous blood sample (5ml) were collected to measure serum Cp, serum Cu, serum SOD, and HbA1c levels by using commercially available kits. The SPSS, version 21, was used for data analysis. Results: The reduced FVC (p-value <0.001), FEV1 (p-value <0.001), and PEFR (p-value <0.001) were found in both groups of diabetes. However, the lower levels of serum Cu (p-value <0.001), SOD (p-value <0.001), and significantly increased values of FEV1/ FVC (p-value <0.001) and Cp levels (p-value 0.030) were found only in T2D group as compared to T1D and controls. The study found no significant correlation of PFTs and serum Cp, Cu, and SOD levels in patients suffering from T1D and T2D. Conclusion: Hyperglycemia leads to more non-enzymatic glycosylation of tissue proteins that reflects reduced PFTs and increased Cp; particularly in T2D, which may alter lung tissue's physiology. Moreover, the study showed no correlation of PFTs with the Cp, Cu, and SOD in patients suffering from T1D and T2D.

Changes in the prevalence of diabetes, prediabetes and associated risk factors in rural Baluchistan; a secondary analysis from repeated surveys (2002-2017).

To observe trends of diabetes and its associated risk factors from health surveys 2002-2017 in rural areas of Baluchistan-Pakistan and a secondary analysis based on community based health surveys of Baluchistan conducted between 2001-02, 2009-10, and 2016-17. A total of 4250 participants were included in this combined analysis, 2515 from 2001-2002, 1377 from 2009-2010 and 358 from 2016-2017 survey year. In each survey, detailed information of baseline parameters were noted on a predesigned questionnaire. Fasting plasma glucose (FPG) was used for diagnosis of diabetes for comparative purposes in this analysis. Cardiovascular (CVD) risk factors including hypertension, obesity, dyslipidaemia, tobacco use, alcohol consumption, and physical activity were compared. Most subjects were aged 30-50 years and males were found higher in 2016-17 compared to 2001-02 and 2009-10. Pronounced increases in BMI, waist circumference, blood pressure, and family history of diabetes were observed in 2016-17. Diabetes prevalence was 4.2 (3.4-4.9), 7.8 (6.6-9.2) and 31.9 (26.9-37.4), whilst pre-diabetes was 1.7 (1.3-2.2), 3.6 (2.8-4.6) and 10.7 (7.6-14.9) in years 2001-02, 2009-10, and 2016-17, respectively. Among those aged 20-39years, prevalence of diabetes was stable from 2001-10 yet increased considerably between the ages of 30-39years in 2016-17. Throughout the observed period, rapid increases were observed in hypertension, obesity, and dyslipidaemia, however, addiction to tobacco use and alcohol intake decreased. Adjusted odd ratios showed age, marital status, education, hypertension, and family history of diabetes as associated risk factors for glycaemic dysregulation. The rural Baluchistan population is confronted with increasing trends of early onset diabetes due to highly associated CVD risk factors, especially central obesity and dyslipidaemia, raising a major public health challenge.

Association of Hepcidin levels in Type 2 Diabetes Mellitus treated with metformin or combined anti-diabetic agents in Pakistani population.

Objective: To evaluate the impact of hepcidin and ferritin in pathogenesis and prognosis of type 2 diabetes mellitus subjects taking only metformin or combined anti-glycaemic agents. METHODS: The observational case-control study was conducted at the Department of Physiology, Baqai Medical University, Karachi, from August 2019 to October 2020, and comprised subjects from both genders who categorised into equal groups as non-diabetic controls, newly-diagnosed type 2 diabetes mellitus patients without any treatment, type 2 diabetes mellitus patients with exposure to metformin only, type 2 diabetes mellitus patients taking oral hypoglycaemic agents along with metformin, type 2 diabetes mellitus patients taking only insulin, and type 2 diabetes mellitus patients taking insulin and oral hypoglycaemic agents. Fasting plasma glucose was determined using glucose oxidase-peroxidase method, glycated haemoglobin by high performance liquid chromatography, high-density lipoprotein and low-density lipoprotein by direct methods, cholesterol by cholesterol oxidase phenol 4-amino antipyrine peroxidase and triglycerides by glycerol phosphate oxidase-phenol 4-amino antipyrine peroxidase method. Serum levels of ferritin, insulin and hepcidin were evaluated using Enzyme-linked immunosorbent assay. Insulin resistance was assessed using homeostasis model assessment for insulin resistance. Data was analysed using SPSS 21. RESULTS: Of the 300 subjects, there were 50(16.66%) in each of the 6 groups. Overall, there were 144(48%) males and 155(51.66%) females. The mean age was significantly lower in the control group 34.72±7.87 compared to all the diabetic groups (p<0.05), and the same was the case with respect to all the parameters (p<0.05) except high-density lipoprotein (p>0.05). Besides, hepcidin level was significantly higher in the control group (p<0.05). Ferritin levels were significantly increased in newly-diagnosed T2DM subjects compared to the controls (p<0.05) while all other groups showed decreased ferritin levels (p<0.05). Hepcidin gave inverse correlation with glycated haemoglobin only in diabetics taking only metformin (r = -0.27, p=0.05). CONCLUSIONS: Anti-diabetes drugs not only addressed type 2 diabetes mellitus, but also reduced levels of ferritin and hepcidin that are found to play a role in diabetes development.

Clinically significant endoscopic findings in a dyspeptic rural population cohort of Sindh, Pakistan: Are we over-investigating?

Objectives: To discuss the clinically significant endoscopic findings of the upper GI tract and their association with different age groups in a dyspeptic rural population of Gadap town, Sindh. Methods: This was a retrospective secondary data analysis of 806 patients conducted in the medical ward of Fatima Hospital, Baqai Medical University from December 2016 to May 2019. It was approved by the University Ethics Committee. Patients' demographics and other data related to the procedure were recovered from patients' records. SPSS version 20 was used for statistical analysis. Results: There were marginally more women suffering from dyspepsia as opposed to men (51.5% vs 48.5% respectively). Majority of the patients were less than 45 years of age, with most procedures being performed as outpatients. Nearly 40% of the patients did not have clinically relevant endoscopic findings. Most common significant finding on endoscopic examination was gastritis followed by hiatal hernia. Conclusion: Normal upper gastrointestinal endoscopy, regardless of age, is a common finding in patients suffering from dyspepsia in our setting. Therefore, in a resource constraint environment like ours, expensive endoscopic procedures should be reserved for those patients who are not responding to medical therapy or those who have alarm symptoms.

Effects of varying levels of gonadotropins and estrogen in adolescent females having type 1 diabetes with their impact on health-related quality of life in Karachi Pakistan.

The purpose of this study is to evaluate quality of life, the gonadotropins and estrogen levels in type 1 diabetic adolescent females. This cross-sectional study was conducted at Baqai Institute of Diabetology and Endocrinology (BIDE). The Diabetes quality of life for youth questionnaire (DQOLY) was used to evaluate quality of life. FSH was found to be significantly lower in Type 1 Diabetes. HbA1c had a significant inverse moderate correlation with FSH(-0.300*).In Type 1 Diabetes, FSH had a positive moderate correlation with LH(0.415*), (P-value<0.05). LH and estradiol levels were almost similar in both groups. Overall mean percentage score of DQOLY questionnaire for Type 1 Diabetes was 26.94±1.36. Low QOL score was observed on the basis of impact on activities. Adolescent females with Type 1 Diabetes were found to be shorter and underweight than non-diabetic adolescent females. Lower height and weight of the diabetes as compared to controls cannot be attributed to only metabolic control, suggesting other mechanisms for short stature. Control on metabolism has always been the target for diabetes treatment for ensuring the improved prognosis of disease but also for the quality of life in Type 1 diabetes.

Glycemic status and general characteristics among individuals with undiagnosed diabetes; findings from second National Diabetes Survey of Pakistan 2016-2017 (NDSP 08).

BACKGROUND AND AIM: To observe the glycemic status among individuals with undiagnosed diabetes in urban and rural areas of all four provinces of Pakistan. METHODS: The findings of this study are obtained from the second National Diabetes Survey of Pakistan (NDSP) 2016-2017, a nationwide epidemiological survey. Out of 12,486 individuals approached, 10,834 participants agreed to be included in the second NDSP. An oral glucose tolerance test was used to assess undiagnosed diabetes individuals according to World Health Organization criteria. RESULTS: The overall weighted prevalence of undiagnosed diabetes was 7.1% (2.4% in urban and 4.7% in rural areas). Based on isolated fasting plasma glucose or 2-h post 75 gm glucose load or combining both, the weighted prevalence of undiagnosed diabetes was 43.5%, 17.6%, and 38.9%, respectively. Out of the 43.5% of individuals, 15.3% had fasting plasma glucose higher than 250 mg/dl at the time of presentation. Among all the individuals, 23.7% were found to be of less than 40 years of age, 29.2% had a positive family history of diabetes, 80.8% were abdominal obese, 53.8% were hypertensive, and 98% were dyslipidemic. In comparison to the elder group, poor glycemic control of ≥10% HbA1c was observed in most of the younger age groups (p < 0.05). CONCLUSION: A significant number of people remain undiagnosed in this part of the world. The glycemic status along with the other associated risk factors at the time of presentation is alarming. Thus, for the early detection of diabetes, awareness and education in the community are crucial. Hence, long-term complications of diabetes can be prevented.

Clinical Association of Biochemical Variations Among Multilocus Genotypes of Antioxidant Enzymes with Susceptibility of Cataract in Hyperglycemia.

Hyperglycemia plays a pronounced role in accelerating the process of aging due to high oxidative stress which triggers dyslipidemia and subsequently led to the progression of cataract. The aim of this study was to investigate lipid profile and its relationship with genotypes of SOD1, GPX1, and CAT variants in cataract patients. Total n = 680 samples were screened in four groups: senile cataract (SC), diabetic cataract (DC), type 2 diabetes mellitus (DM), and controls (CL). Lipid profile was estimated and compared between groups, and its correlation was tested with glycemic markers. Association of SOD1 50 bp Indel, GPX1 (rs1800668), and CAT (rs1001179) genotypes with all clinical variables was investigated in cataract groups by regression statistics in SPSS® 16.0. Comparative analysis revealed that amount of total cholesterol and low-density lipoprotein parameters were significantly higher in both groups of cataracts when compared with controls (p < 0.01). Statistically higher levels of triglycerides were also evident in DM patients as compared with other three groups (p < 0.01). Significant weak positive correlation of glycated hemoglobin, fasting (FBG), and random blood glucose (RBG) levels was observed with triglycerides in DM (r = 0.16), SC (r = 0.15), and DC (r = 0.18) groups. Mutant genotype of SOD1 and CAT variants indicated significant association with TC, whereas GPX1 variant with FBG levels in accelerating predisposition of cataract in patients with diabetes (OR > 1.0). Outcomes suggested that TG may serve as a potential biomarker of lipid profile with manifestation of cataract in type 2 DM. Furthermore, hypercholesterolemia and hypertriglyceridemia demonstrated an inducing role in the pathogenesis of cataract with aging in hyperglycemia.

NDSP-10: The Cardiometabolic Risk Profile with Various Degrees of Dysglycemia in Younger and Older Adults: Findings from the Second National Diabetes Survey of Pakistan 2016-2017.

Background: To assess and compare the cardiometabolic risk profile of the Pakistani population between younger (<45 years) and older adults (≥45 years). Methods: This is a substudy of a nationally representative community-based epidemiological second National Diabetes Survey of Pakistan (NDSP) 2016-2017. Out of 12,486 individuals approached, 10,834 participants agreed to be included (response rate 87%). Cardiovascular risk factors assessed were obesity, central obesity, hypertension, diabetes, hyperlipidemia, and tobacco use. Participants were stratified into young adults (<45 years) and older adults (≥45 years) and was subcategorized into four groups that is, diagnosed diabetes mellitus (DM), undiagnosed DM, prediabetes, and without diabetes. Results: Around 14.3% were prediabetes, 8.8% were undiagnosed DM, and 24% were diagnosed diabetes. Most participants in dysglycemic (prediabetes, undiagnosed DM, and diagnosed DM) groups were females and were from rural regions. Cardiovascular disease (CVD) risk factors were more noted in dysglycemic states, compared with without diabetes. Overall CVD risk profile was worse in males in both age categories, although the accumulation of four or five CVD risk factors at one point was more predominant in females in either age group. Conclusion: Overall, the preponderance of CVD risk factors, such as overweight, obesity, central obesity, tobacco use, ex-tobacco uses, and dyslipidemia, were substantially more prevalent in dysglycemia groups of young adults (<45 years) compared with older adults (≥45 years). Early and targeted intervention in young may prevent poor CVD outcomes as they age.

Association of fibrinogen and plasminogen activator inhibitor-1 with diabetes mellitus.

As the state of hyperfibrinogenemia in diabetes patients occurs due to hyperglycemia which also activates the coagulative cascade ultimately stimulating hepatic fibrinogen synthesis and thus increases clotting factors and PAI-1 levels in the blood. Therefore, in present study our aim is to correlate between type of diabetes and plasma fibrinogen level and plasminogen activator inhibitor-1. This cross sectional study was conducted at Baqai Medical University (BMU) with the collaboration of Baqai Institute of Diabetology and Endocrinology, Karachi. Data was collected from 161 subjects, out of which 51 were control and 55 were subjects in each type 1 diabetes, type 2 diabetes simultaneously. Anthropometric measurements included measurement of weight, height, BMI and blood pressure which were done for each participant. Blood sugar levels and glycated hemoglobin, lipid profile, PAI-1 and fibrinogen were measured in cases and controls. Out of 161 subjects, 80 (49.7%) were male and 81 (50.3%) were female with mean age of 37.75±1.25 years. Fibrinogen level was significantly decreased in healthy subjects as compared to type 1 and type 2 diabetes subjects P-value<0.0001, however no significant difference was observed in fibrinogen level of type 1 diabetes subjects and type 2 diabetes subjects. Plasminogen activator inhibitor-1 of type 2 diabetes subjects was significantly increased as compared to type 1 diabetes subjects (P-value<0.05) but not significantly different to healthy subjects (P-value>0.05). Since, fibrinogen and plasminogen activator inhibitor type 1 was increased in diabetes patients this predisposed them to increased risk of coronary artery disease, our study further supports the clinical observation that diabetes is a thrombophillic condition.

Predisposition of SOD1, GPX1, CAT genetic variants and their haplotypes in cataractogenesis of type 2 diabetes mellitus in Pakistan.

AIMS: Cataract formation is accelerated by hyperglycemia due to the excessive production of oxidative stress. This study aimed to examine the underlaying role of glutathione peroxidase 1 (GPX1) rs1800668, catalase (CAT) rs1001179 and superoxide dismutase 1 (SOD1) 50 bp Indel promotor region variants in the pathogenesis of cataract in patients with diabetes. METHODS: A population-based case-control study of n=680 individuals was conducted which comprised of four respective groups: type 2 diabetes mellitus, diabetic cataract, senile cataract patients and controls. Screening of genotypes was performed by allele-specific (AS) and conventional polymerase chain reaction (PCR). Statistical testing was carried out using SPSS© 20.0, MedCal© and SNPStats© software's. Bioinformatics analysis of linkage disequilibrium was done by HaploView© software 7.0. RESULTS: GPX1 (rs1800668) showed significant association with higher susceptibility of opacification in type 2 diabetes mellitus (χ2=23.0, Adjusted OR=1.63, 95% CI: 1.05-2.49, p<0.001). A protective role was anticipated by CAT variant (rs1001179) for the development of resistance against the pathogenicity of cataract with diabetes (χ2 = 107, Adjusted OR=0.17, 95% CI: 0.10-0.29, p<0.001). Linkage disequilibrium (LD) plot of GPX1 and CAT variants revealed that CTC-CTT haplotypes demonstrated the presence of linkage (D'=1.0) and co-inheritance (LOD=13.84) in patients of diabetic cataract. CONCLUSIONS: GPX1 (rs1800668) variant may serve as an antioxidant biomarker for the assessment of risk for cataract in type 2 diabetes mellitus. GPX1 enzyme owed an antioxidant activity which can reduce the oxidative stress and hence could develop resistance in cataractogenesis. The findings could be beneficial as a potential target to the future pharmacogenomic studies of cataract prevention and eradication in diabetes mellitus.

Comprehensive genetic screening reveals wide spectrum of genetic variants in monogenic forms of diabetes among Pakistani population.

BACKGROUND: Monogenic forms of diabetes (MFD) are single gene disorders. Their diagnosis is challenging, and symptoms overlap with type 1 and type 2 diabetes. AIM: To identify the genetic variants responsible for MFD in the Pakistani population and their frequencies. METHODS: A total of 184 patients suspected of having MFD were enrolled. The inclusion criterion was diabetes with onset below 25 years of age. Brief demographic and clinical information were taken from the participants. The maturity-onset diabetes of the young (MODY) probability score was calculated, and glutamate decarboxylase ELISA was performed. Antibody negative patients and features resembling MODY were selected (n = 28) for exome sequencing to identify the pathogenic variants. RESULTS: A total of eight missense novel or very low-frequency variants were identified in 7 patients. Three variants were found in genes for MODY, i.e. HNF1A (c.169C>A, p.Leu57Met), KLF11 (c.401G>C, p.Gly134Ala), and HNF1B (c.1058C>T, p.Ser353Leu). Five variants were found in genes other than the 14 known MODY genes, i.e. RFX6 (c.919G>A, p.Glu307Lys), WFS1 (c.478G>A, p.Glu160Lys) and WFS1 (c.517G>A, p.Glu173Lys), RFX6 (c.1212T>A, p.His404Gln) and ZBTB20 (c.1049G>A, p.Arg350His). CONCLUSION: The study showed wide spectrum of genetic variants potentially causing MFD in the Pakistani population. The MODY genes prevalent in European population (GCK, HNF1A, and HNF4a) were not found to be common in our population. Identification of novel variants will further help to understand the role of different genes causing the pathogenicity in MODY patient and their proper management and diagnosis.

Association of IL-6 & IL-1ß (pro-inflammatory cytokines) and related biochemical indexes in newly diagnosed diabetics subjected to glucose tolerance test.

The study proposed to find out the association of pro-inflammatory cytokines (IL-6 & IL-1ß) and related biochemical indexes in newly diagnosed diabetes (NDD) subjects as compared to healthy subjects. This clinical prospective research was done with collaboration of University of Karachi and Baqai Institute of Diabetology and Endocrinology between November 2018 to May 2019. Demographics and anthropometric details were noted on predesigned questionnaire. Subjects were identified on the basis of Oral Glucose Tolerance Test (OGTT). Samples of blood at baseline were gained for IL-6 & IL-1ß (pro-inflammatory cytokines) and related biochemical indexes. Total of 34 subjects were included both males 19 (55.9%) and females 15 (44.1%) having mean age 49.65±1.95 years. On the basis of OGTT, 17(50%) were healthy subjects and 17(50%) were NDD. Mean ± SE value of IL-1ß was 208.56±23.53 in healthy subjects and 1510.47±494.16 in NDD subjects, while, IL-6 was 57.51±13.02 and 119.51±36.60, respectively. Non-significant correlation was observed between IL-6 and IL- 1ß (r= 0.20, P=0.475) among healthy subjects. While, significant correlation was observed between IL- 6 and IL- 1ß (r=0.774, P<0.0001) among NDD subjects. With increased levels of both IL-6 and IL-1ß in NDD subjects only IL-1ß showed significant correlation as compared to IL-6. In addition, significant correlation of IL-1ß with various biochemical parameters as compared to IL-6 were also observed to be involved in progression from normoglycemia to type 2 DM.

Psychometric Analysis for fear of COVID-19 Scale (FCV-19S) and its association with depression in patients with diabetes: A cross sectional study from a Tertiary Care Centre in Karachi, Pakistan.

BACKGROUND AND AIMS: To assess the psychometric properties of the Fear of COVID-19 (FCV-19S) scale and to determine its associated factors among the Pakistani patients with diabetes. METHODS: This observational study was conducted in 24-h helpline service, a department of Baqai Institute of Diabetology and Endocrinology (BIDE). Study duration was from August to September 2020. The target population was registered adult patients with type 2 diabetes aged >16 years. Baseline demographic details were obtained from hospital management system of BIDE. Forward-backward translation method was used to translate the existing Fear scale (FCV-19S). Symptoms of depressive disorder were assessed through Patient Health Questionnaire (PHQ9). RESULTS: Total of 380 participants with mean age 51.93 ± 12.03 years contributed in the study. Three factors loading and item correlation of fear COVID-19 explained 96% of total variance having unidimensional Cronbach's alpha of 0.881. All demographic indicators that showed significance in univariate model were included in multivariate model. Females had more fear for COVID-19 compared to males (OR = 1.73, 95% CI (1.15-2.6)), whereas current smokers had also showed 4 times more fear than non-smokers (OR = 4.19, 95% CI (1.18-14.83). Depression assessed by PHQ9 showed maximum fear of COVID-19 in participants with moderate depression. CONCLUSION: FCV-19S had adequate psychometric properties for assessing effects of pandemic in people with diabetes attending tertiary care center.

Fasting Glucagon Level in Type 2 Diabetes and Impaired Glucose Tolerance and Its Association With Diabetes-Associated Clinical Parameters: A Study From Karachi, Pakistan.

Aim and objective The study aims to analyze fasting glucagon in patients with type 2 diabetes and impaired glucose tolerance and correlate it with anthropometric and biochemical parameters in a large proportion of Pakistani people with diabetes.  Methodology The participants of the study were categorized into three groups based on oral glucose tolerance test, as per American Diabetes Association guidelines. Group A consisted of normal glucose tolerance subjects (n=30), Group B consisted of subjects with impaired glucose tolerance (n=30), and Group C had full-blown subjects with type 2 diabetes (n=30). Biochemical parameters, such as fasting glucagon, fasting plasma and 2-hour glucose, glycated hemoglobin, and lipid profile, and anthropometric parameters, such as body mass index (BMI), waist and hip circumference, waist-to-hip ratio, and systolic and diastolic blood pressure, were measured. Results The mean values of fasting glucagon level in Group A, Group B, and Group C were 39.24±4.5, 44.5±8.25, and 49.02±9.15 pg/ml, respectively. Statistically significant difference was not found in fasting glucagon level among these groups (p-value 0.614). Fasting glucagon was positively and independently correlated with 2-hour plasma glucose, systolic blood pressure, diastolic blood pressure, BMI, hip and waist circumference, and hip-to-waist ratio in Group C. In Group B, fasting glucagon was positively correlated with 2-hour plasma glucose, BMI, and hip circumference, while it was not correlated with fasting plasma glucose in both groups. In Group A, fasting glucagon found positively correlated with systolic blood pressure and hip circumference. Conclusion Our observation suggests that fasting plasma glucose is not concomitant with glucagon levels; however, glucagon suppression, after glucose intake, was dysregulated in type 2 diabetes and impaired glucose tolerance. Moreover, glucagon is associated with central obesity in type 2 diabetic patients. .

Predicting the risk of type 2 diabetes through anthropometric indices in Pakistani adults- A sub-analysis of second National diabetes survey of Pakistan 2016-2017 (NDSP-07).

BACKGROUND AND AIM: Excess adiposity is associated with an increased risk of diabetes. Amongst the various measures of adiposity, the most appropriate one to predict the risk of diabetes remains debatable. Therefore, the aim of this study was to compare the ability of body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) in predicting type 2 diabetes mellitus (DM) among Pakistani adults. SUBJECTS AND METHODS: This was the sub-analysis of a large population based Second National Diabetes Survey of Pakistan (NDSP) 2016-2017. With this survey, 10834 individuals were recruited and 4788 individuals fulfilled the inclusion criteria for this sub-analysis (subjects with missing anthropometric details were excluded). Participants were categorized into two groups; subjects with type 2 DM and subjects without DM. Data of participants was collected via pre-designed detailed questionnaire. Clinical and anthropometric measurements were measured using standardized techniques. RESULTS: Out of 4788 individuals, 3085(64.4%) were non-DM subjects and 1703(35.6%) were type 2 DM subjects with mean age of 39.78 ±â€¯13.79 and 50.38 ±â€¯11.33 years, respectively. Logistic regression analysis revealed a significant association of WC with type 2 diabetes after adjustment for possible confounders. Area under the curve (AUC) of WC was found higher than AUC of BMI and WHR. CONCLUSION: The findings from second NDSP (2016-2017) demonstrated that WC is a better marker than WHR and BMI in predicting type 2 DM for Pakistani population.

NDSP 09: Risk Assessment of Pakistani Individual for Diabetes (RAPID) - Findings from Second National Diabetes Survey of Pakistan (NDSP) 2016-2017.

OBJECTIVE: To elucidate the effectiveness of Risk Assessment of Pakistani individuals with diabetes (RAPID) tool in epidemiological and population-based second National Diabetes Survey of Pakistan (NDSP) 2016-2017 for identifying risk of developing type 2 diabetes. METHODOLOGY: This observational study was a sub-analysis of the second National Diabetes Survey of Pakistan (NDSP) 2016-2017 conducted from February 2016 to August 2017 in all four provinces of Pakistan. Ethical approval was obtained from National Bioethics Committee Pakistan. RAPID score, a validated and published scoring scale to assess risk of diabetes, originally developed from community-based surveys was used. The risk score is assessed by parameters namely: age, waist circumference, and positive family history of diabetes. Subjects with score greater ≥4 were considered at risk of diabetes. RESULTS: A total of 4904 individuals were assessed (2205 males and 2699 females). Mean age of participants was 41.8±14.2 years. Positive family history of diabetes was seen in 1379 (28.1%) people. According to RAPID score 1268 (25.9%) individuals scored ≥4 and were at risk of diabetes. OGTT status of people at risk of diabetes according to RAPID score showed that 18.1% people with diabetes and 29.2% were prediabetic. Whereas, OGTT status of people not at risk of diabetes showed that only 7.6% people with diabetes, 20% were prediabetic. CONCLUSION: A simple diabetes risk score can be used for identification of high-risk individuals for diabetes so that timely intervention can be implemented. Community-based awareness programs are needed to educate people regarding healthy lifestyle in order to reduce risk of diabetes.

Upper gastrointestinal endoscopy; A study from a rural population of Sindh, Pakistan.

OBJECTIVE: To discuss common indications and findings on upper gastrointestinal endoscopy as well as to correlate these findings with alarm symptoms in the rural population of Gadap town, Sindh. METHODS: This was a retrospective study on 1288 patients conducted in the medical ward of Fatima Hospital, Baqai Medical University. Patients' demographics and other data related to the procedure were recovered from patients' records. SPSS version 20 was used for statistical analysis. RESULTS: Ratio of male and female patients was approximately 1:1. Majority of the patients were young, and most procedures were done as outpatients without the requirement of conscious sedation. Epigastric pain was the primary indication for upper GI endoscopy (62.6%). One third of the procedures performed did not report any pathological finding. Probability of a positive finding was more likely if a patient presented with dysphagia, heart-burn, hematemesis, vomiting, or for screening endoscopy (for varices). Patients who were diagnosed with esophageal candidiasis, esophageal varices or esophageal growth/ ulcer had reported one or more alarm symptoms in their history. CONCLUSIONS: Upper gastrointestinal endoscopy is a useful test to diagnose disorders of the esophagus, stomach and duodenum. However, it is an expensive procedure and therefore referring physicians should keep appropriate clinical indication and ethical considerations in mind before recommending such an investigation to their patients.

NDSP 06: Prevalence and risk factors for obesity in urban and rural areas of Pakistan: A study from second National Diabetes Survey of Pakistan (NDSP), 2016-2017.

OBJECTIVE: To study the pattern and prevalence of obesity in a large representative sample of Pakistani population aged 20 years and above. METHODOLOGY: This study is a sub analysis of the second National Diabetes Survey of Pakistan (NDSP) 2016-2017, a large community-based epidemiological survey carried out from February 2016 to August 2017 in all 4 provinces of Pakistan. An estimated sample size of 10,834 people was calculated using a multistage sampling technique. Out of 213 clusters, Twenty-seven clusters were selected from all four provinces of Pakistan. Households were identified and selected members of every 10th household were advised to come to the campsite after an overnight fast. All the study participants underwent anthropometric measurements including height, weight, and waist circumference by using standardized techniques and oral glucose tolerance tests were done. Data were analyzed on the statistical package for social sciences (SPSS), version 20. RESULTS: Overall weighted prevalence of generalized obesity was 57.9% (42% in males and 58% in females) and central obesity 73.1% (37.3% in males and 62.7% in females) as per WHO Asia pacific cutoffs. The highest prevalence of generalized obesity was found in Punjab 60%, followed by Khyber, Pakhtunkhwa 59.2%. Moreever, highest prevalence of abdominal obesity was observed in Baluchistan 82.1%, followed by Punjab 73.3%. Obesity (generalized and abdominal) was found significantly associated with diabetes, hypertension, and dyslipidemia. CONCLUSION: The prevalence of obesity is at epidemic proportions in Pakistan, calling for urgent lifestyle intervention strategies to prevent and manage this important cardiometabolic risk factor.

Relationship between diabetic retinopathy and diabetic nephropathy; A longitudinal follow-up study from a tertiary care unit of Karachi, Pakistan.

OBJECTIVE: To determine the development and progression of diabetic retinopathy in subjects with diabetic nephropathy. METHODOLOGY: This retrospective longitudinal follow up study was conducted in outpatient department of Baqai Institute of Diabetology and Endocrinology (BIDE), a tertiary care diabetes unit of Karachi Pakistan, from January 2005 to December 2016. Type 2 diabetic subjects with newly diagnosed diabetic nephropathy (DN) and sex-age matched controls were identified from the electronic database of the institute, Health Management System (HMS). Subjects with type 1 diabetes, gestational diabetes and subjects with diabetic retinopathy (DR) at the baseline of both DN and non-DN group were excluded from the study. Statistical analyses were conducted by using SPSS version 20. RESULT: Out of 3056 type 2 diabetic subjects, 2389 were with DN and 667 were without DN. The incidence of retinopathy was found to be 21.7 per 1000 person years. The incidence rate ratio (IRR) of 2.57 (1.92-3.43) showed that retinopathy was significantly higher in subjects with DN as compared to subjects without DN. Kaplan-Meier survival plot confirmed that subjects with DN had a worse diabetic retinopathy-free survival than subjects without DN. CONCLUSION: Diabetic nephropathy is an independent risk factor for the development and progression of diabetic retinopathy.
