Grabia, M, Markiewicz-Żukowska, R, Socha, K
Nutrients. 2021;(6)
Abstract
Overweight and obesity are an increasingly common problem, not only among the healthy population, but also in adolescents with type 1 diabetes (T1DM). Excess body weight is related to many cardiometabolic complications as well as a high risk of metabolic syndrome (MetS). The purpose of this systematic review is to provide a concise and critical overview of the prevalence of MetS in children and adolescents with T1DM and, ultimately, to discuss prevention and treatment options. The study was conducted in accordance with PRISMA guidelines. This review shows that, apart from the growing percentage of overweight and obese children and adolescents with T1DM (on average 20.1% and 9.5%, respectively), the problem of the increasing incidence of MetS (range from 3.2 to 29.9%, depending on the criteria used) is one of the most important phenomena of our time. One of the methods of prevention and treatment is a combined approach: changing eating habits and lifestyle, but there are also reports about the beneficial effects of the gut microflora.

Abstract
BACKGROUND AND AIMS COVID 19 is a novel pandemic affecting globally. Although no reliable data suggests that patients of well controlled Type 1 Diabetes Mellitus (T1DM) being at increased risk of becoming severely ill with SARS-CoV2, but lockdown may impact patients with T1DM requiring regular medications and follow up. Hence this study was planned to see the impact of lockdown on glycemic control in patients with T1DM. METHODS A cross sectional study was done in T1DM patients in whom a structured questionnaire was administered on follow up within 15 days after lockdown. Data regarding hypoglycemic and hyperglycemic episodes, Diabetic ketoacidosis (DKA), insulin dose missed, regular glucose monitoring, dietary compliance, physical activity, hospitalization during the phase of lockdown was taken. Average blood glucose and HbA1C of lockdown phase was compared with the readings of prelockdown phase. RESULTS Out of 52 patients, 36.5% had hyperglycemic and 15.3% had hypoglycemic episodes. Insulin dose was missed in 26.9%, glucose monitoring not done routinely in 36.5% and 17.4% were not diet compliant during lockdown. Average blood glucose during lockdown phase was 276.9 ± 64.7 mg/dl as compared to 212.3 ± 57.9 mg/dl during prelockdown phase. Mean HbA1c value of lockdown (10 ± 1.5%) which was much higher that of pre lockdown (8.8 ± 1.3%) and the difference was statistically significant (p < 0.05). CONCLUSION Glycemic control of T1DM patients has worsened mainly due to non availability of insulin/glucostrips during lockdown period. There is a need for preparedness in future so that complications can be minimised.

Carbohydrate Restriction in Type 1 Diabetes: A Realistic Therapy for Improved Glycaemic Control and Athletic Performance?
Scott, SN, Anderson, L, Morton, JP, Wagenmakers, AJM, Riddell, MC
Nutrients. 2019;(5)
Abstract
Around 80% of individuals with Type 1 diabetes (T1D) in the United States do not achieve glycaemic targets and the prevalence of comorbidities suggests that novel therapeutic strategies, including lifestyle modification, are needed. Current nutrition guidelines suggest a flexible approach to carbohydrate intake matched with intensive insulin therapy. These guidelines are designed to facilitate greater freedom around nutritional choices but they may lead to higher caloric intakes and potentially unhealthy eating patterns that are contributing to the high prevalence of obesity and metabolic syndrome in people with T1D. Low carbohydrate diets (LCD; <130 g/day) may represent a means to improve glycaemic control and metabolic health in people with T1D. Regular recreational exercise or achieving a high level of athletic performance is important for many living with T1D. Research conducted on people without T1D suggests that training with reduced carbohydrate availability (often termed "train low") enhances metabolic adaptation compared to training with normal or high carbohydrate availability. However, these "train low" practices have not been tested in athletes with T1D. This review aims to investigate the known pros and cons of LCDs as a potentially effective, achievable, and safe therapy to improve glycaemic control and metabolic health in people with T1D. Secondly, we discuss the potential for low, restricted, or periodised carbohydrate diets in athletes with T1D.

De Block, CEM, Shivalkar, B, Goovaerts, W, Brits, T, Carpentier, K, Verrijken, A, Van Hoof, V, Parizel, PM, Vrints, C, Van Gaal, LF
Journal of diabetes and its complications. 2018;(3):271-278
Abstract
AIMS: Type 1 diabetic patients (T1DM) experience a higher cardiovascular disease and mortality risk than controls. We investigated whether visceral adipose tissue (VAT) contributes to coronary artery calcifications (CAC) and cardiac dysfunction in T1DM. METHODS A cross-sectional study of 118 T1DM patients without a history of cardiovascular disease (men/women: 68/50, age 46±12years, HbA1c 7.6±0.9%, BMI 25.8±4.1kg/m2) was conducted. CAC and VAT were measured using a CT scan. CAC was scored using the Agatston method. Cardiac functional abnormalities were assessed by echocardiography. RESULTS CAC scored ≥10 in 42% of patients. Systolic function was normal in all, but diastolic dysfunction was present in 75%. Forty-six percent had VAT≥100cm2. CAC score≥10 occurred more often in subjects with VAT≥100cm2 (54% vs 31%; p=0.01). Age (OR=1.10; p<0.0001), diabetes duration (OR=1.10; p=0.008), gender (OR=4.28; p=0.016), LDL-cholesterol (OR=1.03; p=0.009) and metabolic syndrome (OR=5.79; p=0.005) were independently associated with a CACS≥10. Subjects with CACS≥10 were more prone to have diastolic dysfunction (84 vs 54%; p=0.03). Factors independently associated with diastolic dysfunction were age (OR=1.11; p=0.002), waist circumference (OR=1.10; p=0.016) and VAT (OR=0.99; p=0.035). CONCLUSIONS Excess VAT in T1DM, present in 46%, is associated with diastolic dysfunction and CAC, present in respectively 75% and 42% of patients. Timely detection might improve future cardiovascular risk.

Diabetes & metabolic syndrome. 2017;:S771-S774
Abstract
OBJECTIVE Classification of diabetes mellitus (DM) into type 1 or type 2 is difficult in lean, young individuals. We studied the β-cell function, insulin resistance (IR) and autoimmunity in young patients with recent onset DM. METHODS In this cross-sectional study, we included patients (age below 35 years) with recent onset DM (<6 months) and normal body weight for evaluation. The detailed clinical examination was done to identify markers of IR. Autoimmune DM was diagnosed using glutamic acid decarboxylase 65 (GAD65), insulin autoantibody (IAA) and islet cell antibody (ICA). Homeostasis model assessment (HOMA) models of HOMA-B and HOMA- IR were used for estimation of β-cell function and IR respectively. The patients were divided into four groups based on, the autoimmunity (A) and ketosis (K) as group 1 (A+K), group 2 (A-K+), group 3 (A+K-) and group 4 (A-K-). Appropriate statistical tests +)were used to analyze the results. RESULTS The study population (n=75, all males) had a mean age of 28.9±4.3years, body mass index 20.6±1.9kg/m2, fasting plasma glucose 177.1±31.4mg/dl and HbA1c of 9.9±2.1% at presentation. The number of patients in groups 1 to 4 are 8, 5, 10 and 52 respectively (p<0.0001). HOMA-IR was higher in groups 2 and 4 (4.1±1.3, 3.6±1.1 respectively), whereas HOMA-B was higher in group 4 (3.6±1.5) alone (p=0.0005). CONCLUSION Type 2 DM is the most common etiology even in young, lean adults in India. Further studies with large numbers are required to confirm our findings.

Diabetes microvascular complications-A clinical update.
Khalil, H
Diabetes & metabolic syndrome. 2017;:S133-S139
Abstract
BACKGROUND The purpose of this study is to summarise the empirical evidence addressing diabetes microvascular complications and management. The effects of diabetes mellitus include long-term damage, dysfunction and failure of various organs. Microvascular disease tends to occur predominantly in tissues where glucose uptake is independent of insulin activity because these tissues are exposed to glucose levels that correlate very closely with blood glucose levels. These metabolic injuries cause altered blood flow and changes in endothelial permeability, extravascular protein deposition and coagulation resulting in organ dysfunction which in turn lead to microvascular complications. METHOD A systematic search of the literature from 2000 to 2016 was conducted using four databases (Medline, Pubmed, Cochrane central and Google scholar) using search terms such as diabetic microvascular complications', pathogenesis, screening, risk factors, pharmacological and non-pharmacological interventions and management. RESULTS The current evidence supports a direct relationship between blood pressure (BP) and glycaemic control and progression of nephropathy and retinopathy. These are now considered as independent risk factors for microvascular disease progression. New fields of research addressing new drugs as potential therapeutic targets of the future will be presented. CONCLUSION The prevention of microvascular disease involves paying attention to aggravating risk factors and implementing screening programmes to improve early detection.

Peripheral neuropathy in prediabetes and the metabolic syndrome.
Stino, AM, Smith, AG
Journal of diabetes investigation. 2017;(5):646-655
Abstract
Peripheral neuropathy is a major cause of disability worldwide. Diabetes is the most common cause of neuropathy, accounting for 50% of cases. Over half of people with diabetes develop neuropathy, and diabetic peripheral neuropathy (DPN) is a major cause of reduced quality of life due to pain, sensory loss, gait instability, fall-related injury, and foot ulceration and amputation. Most patients with non-diabetic neuropathy have cryptogenic sensory peripheral neuropathy (CSPN). A growing body of literature links prediabetes, obesity and metabolic syndrome to the risk of both DPN and CSPN. This association might be particularly strong in type 2 diabetes patients. There are no effective medical treatments for CSPN or DPN, and aggressive glycemic control is an effective approach to neuropathy risk reduction only in type 1 diabetes. Several studies suggest lifestyle-based treatments that integrate dietary counseling with exercise might be a promising therapeutic approach to early DPN in type 2 diabetes and CSPN associated with prediabetes, obesity and metabolic syndrome.

The effect of Ramadan fasting on glycaemic control in insulin dependent diabetic patients: A literature review.
Alabbood, MH, Ho, KW, Simons, MR
Diabetes & metabolic syndrome. 2017;(1):83-87
Abstract
BACKGROUND Ramadan fasting is one of the five pillars of Islam. People with diabetes are exempted from fasting according to Islamic rules. However, many people with diabetes wish to fast. Physicians are asked frequently by their patients about their ability to fast and the possible impact of fasting on their glycaemic control. Studies about the effect of Ramadan on people with insulin-treated diabetes are scarce. This review aims to provide clinicians with the best recommendations for their patients with insulin-treated diabetes who wish to fast. METHODS Four databases (Medline, EMBASE, Scopus and PubMed) were searched using the following MeSH terms and keywords: "insulin dependent diabetes mellitus", "type 1 diabetes mellitus", 'Ramadan' "and" "fasting". In addition, a hand search of key journals and reference lists was performed. Sixteen full text articles were selected for review and critical analysis. RESULTS All of the included studies except one found improvement or no change in glycaemic control parameters during Ramadan fasting. The incidence of major complications were negligible. Minor hypoglycaemic events were reported in some studies but did not adversely affect fasting. Postprandial hyperglycaemia was a major concern in other studies. However, the incidence of severe hyperglycaemia and diabetic ketoacidosis were trivial. CONCLUSION Ramadan fasting is feasible for insulin dependent diabetic patient who wish to fast. Clinicians should advise their patients about the importance of adequate glycaemic control before Ramadan and frequent glucose monitoring during fasting. Certain types of Insulin seem to be more beneficial than other.

Rising trend of diabetes mellitus amongst the undernourished: State -of- the -art review.
Francis, NK, Pawar, HS, Mitra, A, Mitra, A
Diabetes & metabolic syndrome. 2017;:S169-S174
Abstract
Diabetes mellitus is prevailing in the malnourished populations congruently in well-nourished ones with an escalating trend in the former group regardless of the absence of obesity as an etiologic determining factor as per the studies in underprivileged sectors of the population. Chronic undernutrition across a lifetime may be an imperative stimulator of diabetes in an individual either by progressively reducing beta cell function alongside islet cell volume and increasing the individual predisposition to other genetic or environmental diabetogenic influences with modifying influence on the course of clinical syndrome. Ketosis resistant insulinopenia is irreversible to the sustained vigorous nutritional convalescence in a substantial fraction of malnourished subjects. It also debunks a latent diabetic stage with insulin resistance reflected by greater insulin requirement in comparison to the patients with type I diabetes with the same beta cell failure fraction and obese type II diabetic patients with equivalent glycemic control gauged by HbA1c levels. Current tendency warrants the replacement of conventional therapy by community oriented theranostic approaches and health programs to curb the epidemic.

Abstract
OBJECTIVE To establish the prevalence of overweight-obesity and metabolic syndrome in a group of paediatric patients with type 1 diabetes (DM1), and to determine the effects on the lipoprotein profile and metabolic control. METHODS A group of 115 patients (5-16 years) with DM1, and on intensive insulin therapy was studied. Weight, height, body mass index (BMI), waist circumference (WC), blood pressure (BP), glycosylated haemoglobin (HbA1c), total cholesterol (TC), HDL-cholesterol (HDL-c), LDL-cholesterol (LDL-c) and triglycerides (TG) were measured. The results were stratified by sex and age (< 11 years and ≥ 11 years). RESULTS The prevalence of overweight and obesity (according to Hernández's reference values) was 28.69% and 18.26%, respectively, with female predominance in both cases. The prevalence of metabolic syndrome (according to the International Diabetes Federation criteria) was 3.22%. 3.47% The WC adjusted for age and sex was > 90th percentile in 3.47% of cases, and 2.6% had a systolic BP ≥ 130 mmHg and/or a diastolic BP ≥ 85 mmHg. An HDL-c < 40 mg/dl was seen in 4.34%, and 2.6% had TG ≥ 150 mg/dl. Obese patients had lower HDL-c levels and higher LDL-c levels than non-obese subjects. There were no significant differences in HbA1c between patients with overweight-obesity and the rest. CONCLUSIONS Overweight and obesity are common in paediatric patients with DM1. Nevertheless, the prevalence of metabolic syndrome and cardiovascular risk factors is lower than in adult patients. The group of diabetic children with obesity had a lipoprotein profile of cardiovascular risk.
