USPSTF and ISPAD Guidelines on Screening for Prediabetes and Type 2 Diabetes in Children and Adolescents

The rising trends of obesity, metabolic syndrome and diabetes in adults are worrisome globally. The majority of antecedents to adult noncommunicable diseases begin in childhood. Type 2 diabetes is recognized as one of the major diseases that contribute to the NCD burden in childhood. Recently, the US Preventive Services Task Force (USPSTF) and the International Society for Pediatric and Adolescent Diabetes (ISPAD) released their guidelines on diagnosis and management of prediabetes and diabetes in children targeted screening for youth-onset type 2 diabetes is suggested in at-risk children (obese, positive family history of type 2 diabetes, etc.), while the role of screening asymptomatic children is not substantiated. Obesity and insulin resistance are important risk factors for type 2 diabetes. The cutoffs of fasting plasma glucose for the diagnosis of prediabetes and diabetes are >100 to 125 and ?126 mg/dL, respectively. This update briefly summarizes the recommendations on screening for youth-onset prediabetes and type 2 diabetes.

Identification of Glucose and Insulin Patterns during A 5-H Glucose Tolerance Test and Association with Cardiometabolic Risk Factors

ABSTRACT Background: Insulin resistance is key in the pathogenesis of the metabolic syndrome and cardiovascular disease. Objective: We aimed to identify glucose and insulin patterns after a 5-h oral glucose tolerance test (OGTT) in individuals without diabetes and to explore cardiometabolic risk factors, beta-cell function, and insulin sensitivity in each pattern. Methods: We analyzed the 5-h OGTT in a tertiary healthcare center. We identified classes using latent class trajectory analysis and evaluated their association with cardiometabolic risk factors, beta-cell function, and insulin sensitivity surrogates by multinomial logistic regression analysis. Results: We included 1088 5-h OGTT performed between 2013 and 2020 and identified four classes. Class one was associated with normal insulin sensitivity and secretion. Class two showed hyperglycemia, dysinsulinism, and a high-risk cardiometabolic profile (obesity, hypertriglyceridemia, and low high-density lipoprotein [HDL] cholesterol). Class three included older individuals, a higher proportion of males, and a greater prevalence of hypertension, hyperglycemia, hyperinsulinemia, and postprandial hypoglycemia. Finally, class four showed hyperglycemia, dysinsulinism, and hyperinsulinemia; this class had the worst cardiometabolic profile (a high proportion of males, greater age, hypertension, obesity, hypertriglyceridemia, and low HDL cholesterol, p < 0.001 vs. other classes). Conclusions: The latent class analysis approach allows the identification of groups with an adverse cardiometabolic risk factor, and who might benefit from frequent follow-ups and timely multidisciplinary interventions.

Clinical characteristics of pituitary GH adenomas patients with different responses to oral glucose inhibitory GH test / 中华内分泌代谢杂志

Objective:To analyzed clinical characteristics of pituitary growth hormone(GH) adenomas patients with different responses to oral glucose inhibitory GH test.Methods:The clinical data of 50 patients with pituitary GH adenomas newly diagnosed with complete test data and case data in the Department of Endocrinology of Chinese PLA General Hospital was retrospectively analyzed from 2016 to 2021. The cases were divided into two groups according to the cutoff point of GH elevating to 50% of basaline during oral glucose test: abnormal elevation group(A group, n=16) and non-elevation group(B group, n=34). The clinical features, biochemistry, iconography, and immunohistochemistry of the two groups were analyzed. Results:The serum total cholesterol(TC)[(3.9±0.8) vs (4.6±0.9)mmol/L], 120 minutes insulin after glucose loading [11.2(4.4, 25.0) vs 92.0(10.8, 311.8)mU/L], long [1.0(0.4, 2.1) vs 1.5(0.5, 7.3) cm] and short[0.6(0.3, 1.3) vs 1.0(0.5, 5.8)cm] diameters of adenomas in A group were less than those in B group(all P<0.05) while insulin-like growth factor Ⅰ(IGF-Ⅰ) level was higher [(908.2±233.7) vs (743.1±273.1) ng/mL, P<0.05]. There were no significant differences in sex, age, disease course, clinical features, random GH, homeostasis model assessment of insulin resistance index(HOMA-IR), pituitary adenoma site, and invasive properties between the two groups. The immunohistochemical positive rates of ACTH(33% vs 0%) and prolactin(100% vs 28.6%)in A group were higher than those in B group( P<0.05). Conclusion:Pituitary GH adenomas patients with a paradoxical GH response pattern display lower serum TC and 120 minutes insulin levels as well as higher IGF-Ⅰ concentration and proportion of pituitary microadenomas. " Pure" growth hormone tumors may represent entities of a particular class of diseases in acromegaly.

Measuring visfatin levels in saliva: an alternative approach to gestational diabetes screening

ABSTRACT Objective: Oral glucose tolerance testing (OGTT) is the current recommended approach for the diagnosis of gestational diabetes mellitus (GDM). Visfatin is a type of novel adipokine of interest that mostly participates in glucose metabolism and inflammatory processes. We aim to identify a screening technique for GDM using salivary visfatin levels and to establish this technique's value as a screening method compared to OGTT. Materials and methods: This is a cross-sectional case-control study. The cohort was formed from the saliva samples of pregnant patients in their 24th through 28th weeks of gestation. Patients were divided into two groups depending on their GDM status. OGTT and visfatin test results were compared and subjected to further analysis to establish a cutoff value for visfatin testing. Results: ELISA results indicated a significant difference between patients with GDM compared to patients without GDM; the values were 18.89 ± 9.59 and 12.44 ± 8.75, respectively (p: 0.007). A cutoff value of 10.5 ng/mL can be used to detect GDM with 78% sensitivity and 51% specificity. Conclusion: Salivary visfatin levels were significantly higher in patients with GDM. The existence of a differential in the concentration of visfatin in saliva can be utilized to develop a new screening method for GDM.

Hemoglobina glucosilada en el diagnóstico de diabetes gestacional en mujeres mexicanas durante el tercer trimestre / Glycosylated hemoglobin in the diagnosis of gestational diabetes in Mexican women during the third trimester

Resumen El objetivo del trabajo fue analizar los valores de hemoglobina glucosilada en el tercer trimestre de embarazo como predictores alternativos de la diabetes gestacional en pacientes del Noreste de México. Se trata de un estudio retrospectivo de casos y controles a partir de 121 expedientes de pacientes embarazadas, divididos en dos grupos, pacientes con diabetes gestacional (casos) y gestantes con valores glucémicos normales (controles). Se analizaron los factores de riesgo asociados a la diabetes gestacional y se obtuvo un punto de corte para la hemoglobina glucosilada. Se encontró que la obesidad materna, la edad y el antecedente del padecimiento fueron asociados significativamente con la diabetes gestacional. Valores de hemoglobina glucosilada ≥5% incrementaron el riesgo de padecer diabetes mellitus gestacional 4 veces y, aunado a un factor de riesgo, la probabilidad se incrementó 7 veces. Se concluye que los valores de hemoglobina glucosilada en el tercer trimestre de embarazo podrían emplearse como prueba diagnóstica de la diabetes gestacional en pacientes del Noreste de México. Sin embargo, aunque las diferencias encontradas fueron estadísticamente significativas, los resultados se deben interpretar con cautela y requieren su confirmación con estudios que incluyan una muestra mayor.

Abstract The objective of this study was to analise glycosylated hemoglobin values in the third trimester of pregnancy as an alternative predictor of gestational diabetes in North East Mexican cohort patients. This is a retrospective case-control study based on 121 records of pregnant patients, divided into two groups, patients with gestational diabetes (cases) and pregnant women with normal glycemic values (control). The risk factors associated with gestational diabetes were analised and a cut-off point for glycosylated hemogestaglobin was obtained. It was found that maternal obesity, age and a history of the condition were significantly associated with gestational diabetes. Values of glycosylated hemoglobin ≥5% increased the risk of suffering from gestational diabetes 4 times, and coupled with a risk factor, the risk increased 7 times. It is concluded that glycosylated hemoglobin values in the third trimester of pregnancy could be used as a diagnostic test for gestational diabetes in patients from the North East of Mexico. Although the differences found were statistically significant, our results must be interpreted with caution and require confirmation by studies with a larger sample.

Resumo O objetivo deste estudo foi analisar os valores da hemoglobina glicada no terceiro trimestre de gestação como preditores alternativos do diabetes gestacional em pacientes na região nordeste do México. Trata-se de um estudo retrospectivo de casos e controles utilizando 121 prontuários de gestantes divididas em dois grupos; pacientes com diabetes gestacional (casos) e gestantes com valores de glicemia normais (controles). Foram analisados os fatores de risco associados a diabetes gestacional obtendo-se um ponto de corte para a hemoglobina glicada. Descobriu-se que a obesidade materna, idade e antecedentes da doença foram associados significativamente ao diabetes gestacional. Valores da hemoglobina glicada ≥ 5% aumentaram o risco de padecer diabetes mellitus gestacional 4 vezes, e juntamente a um fator de risco, a probabilidade aumentou 7 vezes. Conclui-se que os valores da hemoglobina glicada no terceiro trimestre de gestação poderiam ser usados como teste diagnóstico do diabetes gestacional em pacientes da região nordeste do México. Embora as diferenças encontradas tenham sido estatisticamente significativas, os resultados devem ser interpretados com cautela e requerem confirmação através de estudos que incluam uma amostra maior.

Retrospective analysis of OGTT results of 26 558 pregnant women / 公共卫生与预防医学

Objective To investigate the prevalence of gestational diabetes mellitus (GDM) among pregnant women in Wuhan, and to explore the application value of oral glucose tolerance test (OGTT) results in the screening, diagnosis and treatment of GDM. Methods A retrospective analysis was carried out on the OGTT results of 26 558 pregnant women from Hubei Maternal and Child Health Hospital from January 2018 to December 2018. Results (1) A total of 1 754 cases were diagnosed with GDM, with a positive rate of 6.60%. Among them of 776 had fasting blood glucose ≥5.1mmol/L, 880 had 1-hour blood glucose ≥10.0mmol/L, and 798 had 2-hour blood glucose ≥8.5mmol/L. (2) The positive rates of fasting blood glucose, 1-hour blood glucose, and 2-hour blood glucose in the ≥35-year-old age group were all over two times higher than those in the <35-year-old age group (all P<0.01). (3) The ratio of people with single-point positive, two-point positive and three-point positive was 7:2:1. (4) FBG, 1-hour blood glucose and 2-hour blood glucose concentrations were all positively correlated with each other (all P＜0.01). Among these, the positive correlation between 1-hour blood glucose and 2-hour blood glucose was the most significant (r=0.618, P＜0.01). Conclusions The incidence rate of GDM among pregnant women in Wuhan reached 6.60%, and the prevalence in pregnant women over 35 years old was significantly higher. Blood glucose level during pregnancy should be monitored for early detection and intervention to prevent the development of GDM. The relationship between blood glucose concentrations at different time points in the OGTT test had reference value for clinical diagnosis and treatment.

Effect of Shenqi Maiwei Dihuangtang Combined with Acarbose on Blood Glucose Level，Body Mass Index and Abdominal Fat Thickness in Patients with Impaired Glucose Tolerance / 中国实验方剂学杂志

Objective:To explore the effect of Shenqi Maiwei Dihuangtang （SQMWDH） combined with acarbose on the level of 2-hour oral glucose tolerance test （2 h OGTT），body mass index （BMI）， and abdominal fat thickness in patients with impaired glucose tolerance （IGT）. Method:A total of 130 patients with IGT admitted to the First People's Hospital of Shuangliu District from February 2017 to January 2019 were divided into a control group and a treatment group by a random number table. All patients received conventional treatment， such as diet regulation and exercise. The patients in the control group received additional oral administration of acarbose，while those in the treatment group were treated with SQMWDH based on the control group. Fasting blood glucose （FBG），2 h OGTT， and glycated hemoglobin A1c（HbA1c）levels were measured by the blood glucose meter. Abdominal fat thickness was measured by ultrasound tomography，and serum total cholesterol （TC），triglyceride （TG），adiponectin， and leptin levels in fasting venous blood were measured. Result:After treatment，the total response rate of the treatment group was higher than that of the control group （95.00% vs. 81.67%， <italic>χ</italic>²=5.175，<italic>P</italic><0.05）. Before treatment，there was no significant difference in FBG，2 h OGTT，HbA1c， BMI，waist circumference，abdominal fat thickness，TC，TG，adiponectin， and leptin of IGT patients between the two groups. After treatment，the levels of FBG，2 h OGTT，HbA1c， BMI，waist circumference，abdominal fat thickness，TC，TG，and leptin of IGT patients were lower than those before treatment in both groups （<italic>P</italic><0.05）， and the treatment group was inferior to the control group（<italic>P</italic><0.05，<italic>P</italic><0.01）. The level of adiponectin after treatment was higher than that before treatment in both groups （<italic>P</italic><0.05），and the treatment group was superior to the control group （<italic>P</italic><0.05）. Conclusion:SQMWDH combined with acarbose is effective in treating IGT patients by effectively reducing 2 h OGTT and abdominal fat thickness to alleviate obesity and improve the constitution of patients.

Relationship of abnormal mid-term oral glucose tolerance test and maternal weight gain with adverse pregnancy outcomes in women with gestational diabetes mellitus / 浙江大学学报·医学版

To explore the correlation of mid-term oral glucose tolerance test (OGTT) and maternal weight gain with adverse pregnancy outcomes in women with gestational diabetes mellitus (GDM). A total of 2611 pregnant women with GDM who were examined and delivered in Women's Hospital, Zhejiang University School of Medicine from July 1st 2017 to 30th June 2018 were enrolled in this study. According to the number of abnormal items of mid-term OGTT results or maternal gestational weight gain (GWG), patients were classified. The incidence of adverse perinatal outcomes in each group and its relation with OGTT results and GWG were analyzed. The incidence of gestational hypertension, premature delivery, macrosomia and large for gestational age infant (LGA) in three abnormal items GDM patients were significantly higher than those in one or two abnormal items GDM patients (all <0.017). The incidence of gestational hypertension and premature delivery in two abnormal items GDM patients were higher than those in one abnormal item GDM patients (all <0.017). The incidence of gestational hypertension and macrosomia in excessive GWG patients were significantly higher than those in inadequate and appropriate GWG patients (all <0.017), and the incidence of LGA were higher than that in inadequate GWG patients (all <0.017). The incidence of premature delivery and low birth weight infants in appropriate GWG patients were significantly lower than those in inadequate and excessive GWG patients, and the incidence of small for gestational age infant (SGA) were significantly lower than that in inadequate GWG patients (all <0.017). In one abnormal item GDM patients, inadequate GWG was a risk factor for premature delivery and SGA (=1.66, 95%: 1.10-2.52; =2.20, 95%: 1.07-4.53), and protective factor for LGA (=0.40, 95%: 0.27-0.59). And excessive GWG was a risk factor for gestational hypertension, premature delivery and low birth weight infants (=2.15, 95%: 1.35-3.41; =1.80, 95%: 1.20-2.72; =2.18, 95%: 1.10-4.30).In two abnormal items GDM patients, inadequate GWG was a protective factor for macrosomia and LGA (=0.24, 95%: 0.09-0.67; =0.54, 95%: 0.34-0.86), while excessive GWG was risk factor for premature delivery (=1.98, 95%: 1.23-3.18).In three abnormal items GDM patients, there was no significant relationship between GWG and adverse pregnancy outcomes. For GDM women with one or two items of elevated blood glucose in OGTT, reasonable weight management during pregnancy can reduce the occurrence of adverse pregnancy outcomes. For those with three items of elevated blood glucose in OGTT, more strict blood glucose monitoring and active intervention measures should be taken in addition to weight management during pregnancy.

Analysis of risk factors and establishment of prediction model for post transplantation diabetes mellitus in renal transplant recipients / 器官移植

Objective To analyze the risk factors for the occurrence of post transplantation diabetes mellitus (PTDM) in renal transplant recipients, establish a prediction model for PTDM and evaluate its prediction value. Methods Clinical data of 915 renal transplant recipients were retrospectively analyzed. According to the occurrence of PTDM, all recipients were divided into the PTDM group (n=78) and non-PTDM group (n=837). The main indexes of recipients were collected. The risk factors for the occurrence of PTDM in renal transplant recipients were analyzed by univariate and multivariate analysis. The prediction model for PTDM was established and its prediction value was evaluated. Results Family history of diabetes mellitus, body mass index (BMI), preoperative 2 h postprandial blood glucose and preoperative glycosylated hemoglobin were the independent risk factors for the occurrence of PTDM in renal transplant recipients. The prediction model for PTDM was logit (P)=2.199×family history of diabetes (yes=1, no=0)+0.109×BMI+0.151×2 h postprandial blood glucose (mmol/L)+0.508×glycosylated hemoglobin (%)-9.123. The results of receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) of these 4 predictors combined for predicting PTDM in renal transplant recipients was 0.830 [95% confidence interval (CI) 0.786-0.873], the cut-off value was 0.0608, the sensitivity was 0.821, the specificity was 0.700, and the Youden index was 0.521 (P < 0.05). Conclusions Family history of diabetes mellitus, BMI, preoperative 2 h postprandial blood glucose and preoperative glycosylated hemoglobin are the independent risk factors for the occurrence of PTDM in renal transplant recipients. The prediction model for PTDM combined with4 predictors yield relatively high prediction value for PTDM.

A study of gestational diabetes mellitus and fetal outcome in a tertiary care center

Background: Modern desk-bound lifestyle and unhealthy dietary changes have brought a rise in the prevalence of obesity and gestational diabetes mellitus (GDM). It is associated with severe hazards to the mother and the baby. It is mandatory that early diagnosis ensues and timely and congruous management is undertaken.Methods: In this observational study, 1250 women were included. A standardized questionnaire was formed and their details were noted. Tests for glucose levels, complete blood picture, urine examination were performed. An oral glucose tolerance test was performed on all the patients. Neonatal outcomes in terms of birth weight and the presence of complications were noted.Results: A total 201 (16.1%) of all women were having gestational diabetes mellitus (GDM). Most mothers were in the 25-30 age group. The majority of the women had a BMI between 26-30. 21.9% of babies were having weight >3.5 kgs. 11.4% of babies were <2.5 kgs. Out of 201 neonates, 90 babies were having complications. Major complications in neonates were macrosomia and respiratory distress. Therefore, early diagnosis, glycemic control, and timely and congruous management are advantageous to both mother and baby.Conclusions: GDM complicating the pregnancy results in a higher prevalence of complications in the mother and the neonate. Therefore, appropriate control of the sugar level in mothers is necessary and it decreases the morbidity and mortality rates in the babies as well as the mothers.

Screening of gestational diabetes mellitus using one-step versus two-step method: a comparative study

Background: Gestational diabetes mellitus (GDM) is defined as carbohydrate intolerance of variable severity with onset or first recognition during the present pregnancy. It affects 7% of all pregnancies worldwide and in India it ranges from 6 to 9% in rural and 12 to 21% in urban area. The aim of this study was to compare the DIPSI criteria with the two-step method (Carpenter and Couston criteria.) and to study merits and demerits of one step and two step tests for GDM.Methods: A total 400 pregnant women of gestational age between 24-28 weeks attending antenatal clinic at this study tertiary care center were enrolled in this study. 200 pregnant women were enrolled in each of the study group (Group I OGTT and Group II DIPSI).Results: In Group I (OGTT) screening 47 (23.5%) were tested positive. In Group II cases, screening test results were found positive among 44 (22%). Out of 95 high-risk pregnant women 38 (40%) were positive for GDM by OGTT and 34 (35.78%) were positive by DIPSI. Out of 305 non high-risk pregnant women, 9 (2.95%) were positive for GDM by OGTT and 10 (3.27%) were positive by DIPSI.Conclusions: Present study concludes that DIPSI is the test which can predict GDM in population comparable to another test like OGTT. Also, India’s major population reside in rural areas, ANC are mostly conducted by ANM, therefore screening test should be easy to perform and interpret.

A single abnormal value of 100 g oral glucose tolerance test and pregnancy outcomes

Background: In the worldwide, diabetes mellitus is one of the most common medical complications in pregnancy, the prevalence is about 5% and seems to increase. Objective of this study was to evaluate the effect of a single abnormal value of 100 g OGTT on pregnancy outcomes.Methods: This retrospective cohort study was conducted from January 2014 to December 2018 to identified 600 singleton pregnancies who tested for gestational diabetes by 100g OGTT. They divided into 2 groups equally. Pregnancy outcomes of women who had a single abnormal value were compared with women who had a negative test. Pregnancies with prior cesarean delivery were excluded.Results: Between two groups, the baseline characteristic of the patients were comparable except maternal age [33 (26.37) versus 30 (24.36), p = 0.001] was statistically higher in the study group. Even though the most of adverse pregnancy outcome tend to be higher in study group, but not reach the significance, the rate of cesarean delivery (35.7% versus 25.7, RR 1.39, 95% CI 1.08-1.78), postpartum hemorrhage (38.6% versus 30%, RR 1.29, 95% CI 1.03-1.62) and NICU admission (5.6% versus 1.0%, RR 5.69, 95% CI 1.80-17.96) were higher in study group with significant difference. Caesarean delivery (38.8% versus 28.7%, p = 0.04) and NICU admission (9.5% versus 1.9%, p = 0.0003) were more common if the blood glucose greater than 10 mg/dl normal level.Conclusions: A single abnormal value of 100 g OGTT had significant impact on pregnancy outcome such as increase cesarean section, postpartum hemorrhage and NICU admission.

Sodium-glucose cotransporter-2 inhibitors: updated evidence on their efficacy and safety in patients with type-2 diabetes

Management of type-2 diabetes mellitus (T2DM) is challenging. The scope of existing therapies toward T2DM has transformed remarkably. These large assortments of therapies have produced evidence-based data. Sodium-glucose cotransporter-2 inhibitor (SGLT-2i) is the most recent class of oral anti-hyperglycemic agents. They are approved by Food and Drug Administration for the treatment of diabetes mellitus. SGLT-2i has a unique mechanism of action and that lower glucose independent of insulin. They reduce renal tubular glucose reabsorption, thereby lowering blood glucose without stimulating the release of insulin. Additional advantages involve suitable effects on blood pressure and weight. According to guidelines of the American Association of Clinical Endocrinologists/ the American College of Endocrinology 2016, SGLT-2i (in the form of canagliflozin, dapagliflozin, and empagliflozin) is one of the acceptable alternatives to metformin as initial therapy towards T2DM. Canagliflozin, dapagliflozin, and empagliflozin reduce the cardiovascular risk in comparison to placebo as the part of standard care. This review article focuses on the clinical trials published over the past year and specifically the metabolic aspect of SGLT-2i and the adverse effects related to SGLT-2 inhibitors.

A study comparing non-gestational diabetes mellitus and gestational diabetes mellitus in antenatal patients in a tertiary care center

Background: Gestational diabetes mellitus is defined as any glucose intolerance with the onset or first recognition during pregnancy. Objectives of this study were to diagnose cases of GDM by screening with DIPSI criteria at less than 28 weeks. And observation and comparison of maternal and perinatal outcome in women diagnosed of GDM in less than 20 weeks and at 24-28 weeks.Methods: This was the prospective analytical study conducted in the department of obstetrics and gynecology for one year in Muzaffarnagar medical college and Hospital. After history taking, clinical and obstetrics examination 1503 antenatal patients of less than 28 weeks were enrolled underwent screening with DIPSI criteria. Out of which 80 patients with abnormal OGTT of gestational age less than 20 weeks and 69 patients with abnormal OGTT of gestational age 24 -28 weeks.Results: In early diagnosed GDM group alive and healthy babies were slightly lower as compared with late diagnosed GDM group.Conclusions: The diagnosis of GDM gives us an opportunity in identifying individuals who will be benefitted by early therapeutic intervention with diet, exercise, and normalizing the weight to delay or prevent the onset of the disease.

Effectiveness of diabetes in pregnancy study group India diagnostic criterion in detecting gestational diabetes mellitus: a rural Bangalore study

Background: The oral glucose tolerance test (OGTT) is considered the current standard for diagnosis of gestational diabetes mellitus (GDM). International association of diabetes and pregnancy study groups (IADPSG) recommends OGTT, with fasting, one-hour and two-hour venous blood samples drawn after intake of 75g oral glucose. In the Indian context, diabetes in pregnancy study group in India (DIPSI) recommends glucose challenge test (GCT), where 75 g glucose is given irrespective of the fasting state, and a single venous sample is drawn after two-hour. Diagnosis of GDM is made, if any cut-off value is met or exceeded. This prospective study was conducted to compare the DIPSI and IADPSG criteria for diagnosis of GDM.Methods: Pregnant women between 24 to 28 weeks of gestation were subjected to non-fasting GCT. Capillary sample were also drawn simultaneously using Accu check active glucometer. These women were counselled to undergo a standard 75gram OGTT, within a week of recruitment.Results: According to IADPSG criteria, 17.6% (18/102) of our participants had GDM, as compared to 19.6% (20/102) by DIPSI criteria using venous samples, and 25.3% (25/99) by capillary sample method. Sensitivity and specificity of GCT using venous sample was 72.22% and 91.67%, and using capillary sample was 70.59% and 84.15% respectively. DIPSI criteria using venous samples wrongly labelled 8.3% women as GDM, and capillary samples wrongly labelled 15.9% women as GDM. More importantly DIPSI criteria using venous samples labelled 27.8% women as false-negative and capillary samples labelled 29.4% women as false-negative for GDM. Almost one quarter of women with GDM will be missed if DIPSI criteria is used as a universal screening modality.Conclusions: We suggest that the IADPSG criteria be used for diagnosis of GDM in antenatal women in India.

Fetomaternal Outcome in Gestational Diabetes Mellitus at a Tertiary Care Hospital

Introduction: Gestational diabetes mellitus (GDM) is a common medical problem that results from an increased severityof insulin resistance as well as impairment of the compensatory increase in insulin secretion. GDM has profound effects onfetomaternal outcome.Aims and Objectives: This study aims to evaluate the impact of GDM on pregnancy and fetal outcome.Materials and Methods: The present study was a prospective observational study. The screening was done by glucosechallenge test and 3 h, 100 g glucose tolerance test. The study population was divided into two groups, cases and controls. Allthe patients were followed up for maternal complications, fetal complications, mode of delivery, and neonatal complications.Results: A total of 350 randomly selected pregnant females who met the inclusion criteria were subjected to oral glucosechallenge test. Of 350 women, 22 women were found to have GDM and were compared with non-GDM patients. GDM patientshad significantly higher percentage of pregnancy-induced hypertension (13.6% vs. 2.6%, P = 0.031), polyhydramnios (22.7%vs. 4.3%, P = 0.004), urinary tract infection (40.9% vs. 14.5%, P = 0.003), and excess weight gain (36.4% vs. 6.3%, P = 0.001).GDM patients had higher cesarean deliveries in 13 (59.1%) and assisted vaginal deliveries in 2 (9.1%) as compared to non-GDM(110 [36.3%] and 6 [2%], P = 0.006, respectively). Among the fetal outcome, GDM patients had higher macrosomia (31.8%vs. 8.3% in non-GDM group [P = 0.003]), neonatal convulsions (18.2% vs. 2.3% in non-GDM group [P = 0.003]), respiratorydistress (22.7% vs. 3.3% [P = 0.002]), and neonatal intensive care unit admission (72.7% vs. 12.9% [P = 0.001]).Conclusion: GDM is associated with both maternal and fetal complications, most notably macrosomia leading to increasedcesarean section rate and instrumental deliveries.

A retrospective study to assess prevalence of gestational diabetes mellitus among those who delivered in Saveetha Medical College and Hospital

Background: Gestational diabetes mellitus (GDM) defined as any degree of carbohydrate intolerance with onset or first recognition during pregnancy contributes to about 90% of diabetes complicating pregnancy. GDM imposes risks for both mother and fetus, some of which continues throughout the life of mother and child. The objective of the present study was to determine the prevalence of gestational diabetes mellitus and the associated risk factors among those who delivered in Saveetha medical college and hospital.Methods: A retrospective study was conducted by analysing the medical records of the patients who were admitted in the Department of Obstetrics and Gynaecology over a period of 1 year at Saveetha medical college and hospital, Chennai, Tamil Nadu, India. The diagnosis of GDM was made mainly by 75gm one step oral glucose tolerance test (OGTT). The guideline endorses 2-hours 75-gm OGTT, irrespective of last meal timings with a cut off value of ≥140 mg/dl. All data was analysed by simple descriptive statistics and percentage method.Results: In the present study, the total number of deliveries for 1 year from April 2018 - March 2019 were 511 and among those the total number of antenatal mothers with GDM who delivered were 46. Therefore the prevalence of GDM was calculated to be 9% or 90 per thousand deliveries. In the present study, 37 (65.1%) pregnant women of GDM group were seen in the age group of above 25 years, 27 (58.59%) were multiparous, 25(54.25%) pregnant females with GDM were found to have overweight and obese out of 46 cases.Conclusions: Our current study concludes the Prevalence of GDM in Saveetha Medical College Hospital is 9% between April 2018-March 2019. We have identified the following risk factors for developing GDM: multiparity≥2; previous history of diabetes mellitus; age ≥ 25; BMI ≥25; and family history of diabetes.

Screening for gestational diabetes mellitus by two step method and the pregnancy outcome: a study in Indian women

Background: In recent times, gestational diabetes is becoming more common Worldwide and complications are seen in fetal development, growth, labour and delivery due to maternal hyperglycemia. Gestational Diabetes Mellitus(GDM) is associated with adverse maternal and fetal outcomes. Among South Asian Population, Indian Women are at high risk of developing carbohydrate intolerance during pregnancy. Hence this study is undertaken to screen for gestational diabetes mellitus by two step method in Indian Women.Methods: This study was done in 153 nondiabetic pregnant women of gestational age 24-28 weeks, excluding diabetes mellitus diagnosed prior to pregnancy. Two step method was followed in the present study and GDM was diagnosed and the pregnancy outcomes were noted.Results: In our study the prevalence of GDM is 8.1% by two step method. Most of the women diagnosed with GDM were of age 26-30 yrs (41.66%). Among the women who were diagnosed as GDM, (58.33%) cases required Insulin along with diet control. In our study 33.33% had vaginal delivery, 8.33% had Emergency LSCS and 58.33% had Elective LSCS.Conclusion: Indian Women have high prevalence of GDM, hence universal screening is essential to diagnose GDM, which will improve the pregnancy outcome.

Prevalence of prediabetes in children and its association with risk factors

Background: Type 2 Diabetes is becoming more common at younger age group. It is important to screen children and adolescents for prediabetes to prevent long-term complications of diabetes. This study was conducted to study the prevalence of prediabetes in children and its association with risk factorsMethods: It is a Prospective hospital-based study. Children aged 6 to 18 years admitted in the Pediatric ward of tertiary care hospital were included. Study was done over a period of 2 years November 2015-October 2017. Participants were screened to find out the prevalence of prediabetes. Prediabetes was defined as fasting glucose concentration (FBS)of 100-125 mg/dl or a HbA1c value of between 5.7% and 6.4%, or a two-hour post-glucose tolerance concentration (OGTT) of 140-199mg/dl.Results: 607 children participated in the study.56.3% were males. Prevalence of Prediabetes was 20.4% with a combination of OGTT, FBS and HbA1c tests. Prevalence by OGTT was 5.9%, HbA1c 4.1% and by FBS was 17.1%. Higher prevalence of prediabetes was associated with male gender, frequent consumption of junk foods, decreased physical activities, overweight, obesity and high waist to hip ratio. Combination of FBS with GTT and FBS with' HbA1c had better sensitivity and specificity when compared to combination of OGTT with HbA1c .Conclusion: Screening of children for prediabetes at younger age especially those with risk factors and intervention with lifestyle modification may help in delaying the progression of the disease.

One step procedure for screening and diagnosis of gestational diabetes mellitus by diabetes in pregnancy study group of India

Background: In the Indian context, screening for Diabetes is essential in all pregnant women, as the Indian women have an eleven-fold increased risk of developing glucose intolerance during pregnancy. For this, we need a simple procedure which is economical and feasible. Hence this study was undertaken as a screening as it is acceptable, economical and feasible to perform. Aim of this study was to assess the feasibility of one step procedure for screening and diagnosis of Gestational Diabetes Mellitus by Diabetes in Pregnancy Study Group of India (DIPSI).aim of the study was to study the occurrence of Gestational Diabetes mellitus, Tumkur, to assess the sensitivity and specificity of glucose challenge test, to assess the need for universal screening and to study the maternal and perinatal outcomes in patient with Gestational Diabetes Mellitus.Method: Type of study was prospective study. this study included 200 pregnant women attending the antenatal OPD in Sri Siddhartha Medical College, Tumkur. Data collection was in a predesigned proforma. Pregnant women with 24-28 weeks of gestation were given 75 grams of oral glucose load, irrespective of their meal and venous blood sample drawn after 2 hours. If blood glucose value was ≥140mg/dl, the screening was considered as DIPSI positive. These patients underwent OGTT.Results: Incidence of GDM was found to be 3.5% in the patients studied. 40% of cases did not have risk factors, hencethere is a need for universal screening. DIPSI was positive in 10 cases, of which 7 were OGTT positive. Patients were managed with diet and insulin. The maternal and perinatal outcome of pregnancy was good.Conclusion: For universal screening, DIPSI performed irrespective of last meal timing with 75g glucose load is a patient friendly approach. This method recommended by WHO serves both as a one-step screening and diagnostic procedure & is easy to perform besides being economical.
