Aim: To study the clinical characteristics and incidence of microvascular complications among childhood and adolescent onset type 1 (T1DM) and type 2 diabetes (T2DM) seen at a tertiary care diabetes center in India., Methods: From our electronic medical records, we retrieved clinical and biochemical details of 4555 individuals with childhood and adolescent onset diabetes (diagnosed below the age of 20 years) seen between 1992 and 2017. T1DM was diagnosed if there was history of ketoacidosis or fasting C-peptide <0.3 PMol/mL and stimulated C-peptide <0.6 PMol/mL or if insulin treatment was required from the time of diagnosis. T2DM was diagnosed based on absence of ketosis, or fasting C-peptide ≥0.6 PMol/mL and stimulated >1.0 PMoL/mL, or response to oral hypoglycemic agents for more than 2 years. We calculated the incidence rates of retinopathy (presence of at least one definite microaneurysm by retinal photography), nephropathy (urinary albumin excretion ≥30 μg/mg of creatinine) and neuropathy (vibration perception threshold ≥20 V) per 1000 person-years of follow up., Results: Among the 4555 individuals with childhood and adolescent-onset diabetes, 71.4% had T1DM, 19.5% T2DM and 9.1% other forms of diabetes. Age at first visit and duration of diabetes were significantly higher in T2DM when compared to T1DM. The age adjusted incidence of retinopathy was 52.9/1000 person years (Confidence Intervals [CI]: 42.9-62.8) in T1DM and 49.8/1000 person years (CI 30.8-68.8) in T2DM; nephropathy, 6.2 (CI 3.3-9.0) and 13.8 (CI 5.6-22.0); and neuropathy, 8.8(CI 3.6-14.0) and 24.0 (CI 9.8-38.2) in T1DM and T2DM, respectively., Conclusion: The incidence of microvascular complications is high among childhood and adolescent-onset T1DM and T2DM and these calls for more aggressive control of diabetes., (© 2020 John Wiley & Sons A/S.

Background: The current life expectancy in India is <70 years. Type 2 diabetes mellitus (T2DM) is known to reduce life expectancy by 6-8 years. Hence elderly people with T2DM in India would be rare. We report on the clinical profile of Asian Indian patients with T2DM who lived beyond 90 years of age and compared them with T2DM patients aged 50 to 60 years. Methods: From the diabetes electronic medical records of >470,000 diabetes patients, we identified T2DM patients who had lived ≥90 years and compared them with those in the 50-60 years age group, matched for gender and duration of diabetes. Clinical data included age at last visit, age at diagnosis, duration of diabetes, family history, smoking and alcohol, details of medications, body mass index (BMI), and blood pressure. Biochemical data included fasting and postprandial plasma glucose, glycated hemoglobin, fasting and stimulated C-peptide levels, lipid profile, and renal function studies. Assessment of retinopathy, nephropathy, neuropathy, coronary artery disease (CAD), and peripheral vascular disease (PVD) was also done. Results: A total of 325 T2DM patients aged ≥90 years and 278 T2DM patients aged between 50 and 60 years were selected for the study. Patients aged ≥90 years had higher systolic blood pressure ( P  < 0.001) and lower BMI ( P  < 0.001) than those between 50 and 60 years. Prevalence of retinopathy (29.7% vs. 53.5%) and macroalbuminuria (3.7% vs. 16.0%) was lower in the ≥90 years T2DM patients than in the 50-60 years age group. However, prevalence of neuropathy (89.8% vs. 50.8%), PVD (13.5% vs. 2.0%), and CAD (60.3% vs. 32.0%) was higher among the ≥90 years patients. Eighty-five percent of the T2DM aged ≥90 years were on oral hypoglycemic agents (OHAs), (of whom 64.9% were on sulfonylurea), 12% were on insulin, and 3% on diet alone. Among the 50-60 years old, 87.8% were on OHAs and 12.2% on insulin. Conclusions: This is the first report on the clinical profile of Asian Indians with T2DM aged ≥90 years, and significant differences are seen in their clinical profile compared with younger T2DM patients.

Aim: The aim of this study was to determine the optimal glycated hemoglobin (HbA1c) cut point for diagnosis of gestational diabetes mellitus (GDM) and to evaluate the usefulness of HbA1c as a prognostic indicator for adverse pregnancy outcomes., Methods: HbA1c estimations were carried out in 1459 pregnant women attending antenatal care centers in urban and rural Tamil Nadu in South India. An oral glucose tolerance test was carried out using 75 g anhydrous glucose, and GDM was diagnosed using the International Association of the Diabetes and Pregnancy Study Groups criteria., Results: GDM was diagnosed in 195 women. Receiver operating curves showed a HbA1c cut point of ≥ 5.0% (≥31 mmol/mol) have a sensitivity of 66.2% and specificity of 56.2% for identifying GDM (area under the curve 0.679, confidence interval [CI]: 0.655-0.703). Women with HbA1c ≥ 5.0% (≥31 mmol/mol) were significantly older and had higher body mass index, greater history of previous GDM, and a higher prevalence of macrosomia compared to women with HbA1c < 5.0% (<31 mmol/mol). The adjusted odds ratio for macrosomia in those with HbA1c ≥ 5.0% (≥31 mmol/mol) was 1.92 (CI: 1.24-2.97, P = 0.003). However, other pregnancy outcomes were not significantly different., Conclusion: In Asian Indian pregnant women, a HbA1c of 5.0% (31 mmol/mol) or greater is associated with increased risk of macrosomia., Competing Interests: There are no conflicts of interest.

Aim: To compare the existing maternal and fetal outcomes in Asian Indian women with or without gestational diabetes mellitus (GDM) before the development of the Women in India with GDM Strategy (WINGS) GDM model of care (MOC)., Materials and Methods: Records of pregnant women were extracted retrospectively from three maternity centers in Chennai. GDM was diagnosed using the International Association for Pregnancy Study Groups criteria or the Carpenter and Coustan criteria. Demographic details, obstetric history, antenatal follow-up, treatment for GDM, and outcomes of delivery were collected from the electronic medical records., Results: Of the 3642 records analyzed, 799 (21.9%) had GDM, of whom 456 (57.1%) were treated with insulin and medical nutrition therapy (MNT), 339 (42.4%) with MNT alone, and 4 (0.5%) with metformin. Women with GDM were older than those without (28.5 ± 4.5 vs. 27.1 ± 4.5 years; P < 0.001) and had higher mean body mass index at first booking (26.4 ± 5.2 kg/m(2) vs. 25.2 ± 5.1 kg/m(2); P < 0.001). Rates of cesarean section (26.2% vs. 18.7%; P < 0.001), preeclampsia (1.8% vs. 0.8%; P = 0.04), and macrosomia (13.9% vs. 10.8%; P = 0.02) were significantly higher among women with GDM. In women with GDM treated with insulin and MNT, emergency cesarean section (16.2% vs. 36.6%; P < 0.0001), preeclampsia (0.7% vs. 3.2%; P = 0.015), and macrosomia (9.9% vs. 18.6%; P = 0.0006) were significantly lesser compared to those treated with MNT alone., Conclusion: Pregnancy outcomes were in general worse in GDM women. Treatment with insulin was associated with a significantly lower risk of complications. However, in countries with limited access to insulin and other medicines may lead to poor follow-up and management of GDM. Data from this retrospective study will form the basis for the development of the WINGS GDM MOC, which will address these gaps in GDM care in low-resource settings.

A 53-year-old school teacher presented with progressive exertional breathlessness and dry cough of three months duration. His diagnosis was confirmed as pulmonary alveolar proteinosis on open lung biopsy. In about three months, the disease progressed to life threatening respiratory failure. He was subjected to whole lung lavage (WLL) as a salvage therapy. The technical details of WLL performed on this patient are described. At six months follow up, he was clinically and functionally stable and leading a near normal life.

The present report describes more than nine years of experience with simultaneous removal and replacement of the chronic peritoneal dialysis (PD) catheter in treating refractory mechanical and infectious complications. Simultaneous catheter replacement and removal not only succeeded in 22 of 23 cases with non-infectious mechanical complications, allowing uninterrupted PD in all but three, but also succeeded in 30 (83%) of 36 additional cases with persisting or recurring infection. Simultaneous procedures failed in six (17%) of 36 infectious cases, due to persistent infection in two cases and to procedure complications in four cases. The clinical characteristics of the 30 successful infectious cases were compared to the characteristics of both the six failures, as well as 29 additional infectious cases in which the peritoneal catheter was removed but was not replaced because of a variety of serious complications (such as pancreatitis, abscess, sepsis, or fluid overload). At the time of simultaneous catheter replacement in successful cases, temporary control of active peritoneal inflammation was achieved more frequently (80% vs. 31%, P less than 0.001) with a shorter interval of antibiotic coverage (6.4 +/- 0.9 vs. 14.7 +/- 1.3 days, P less than 0.001). In addition, the successful cases were characterized by significantly more Staphylococcal infections (70% vs. 26%, P less than 0.001) and significantly fewer Pseudomonal or fungal infections (6% vs. 59%, P less than 0.001), although successful cases included some non-Pseudomonal, non-enteric gram negative infections (23%).(ABSTRACT TRUNCATED AT 250 WORDS)
