Introduction: Diabetes is the leading worldwide cause of chronic kidney disease, which is diagnosed by measuring albuminuria and estimating glomerular filtration rate (GFR) with creatinine-based formulas, such as the 2009 CKD-EPI developed in the United States of America (USA). Nonetheless, the race coefficient (RC), present in the 2009 CKD-EPI, may overestimate GFR in other countries.Aim: The goal of this systematic review and meta-analysis was to asses...

The health benefits of exercise are well-recognized and are observed across multiple organ systems. These beneficial effects reduce disease risk and mortality. The molecular mechanisms that underlie the beneficial effects of exercise, however, remain poorly understood. With emergence of –omics technologies, the number of exercise-associated signalling molecules that have been identified has rapidly expanded. Signalling moieties released by skeletal muscle are defined as m...

Background and aims: Diabetic retinopathy (DR) is an important chronic complication of diabetes mellitus (DM), and is the leading cause of new cases of blindness in adults. Although several single nucleotide polymorphisms (SNPs) have been associated with DR, more information is needed to unravel the genetics of this complex disease. MicroRNAs (miRNAs) are a class of small noncoding RNAs that regulate expression of at least 60% of all protein-coding genes. A number of miRNAs ha...

Insulin autoimmune syndrome (IAS; Hirata syndrome) is a rare cause of hypoglycemia. It seems to be related to specific HLA class II alleles. Rarely, monoclonal antibody acts as an insulin-binding autoantibody: until now 10 cases have been described in association with a myeloproliferative disorder. In June 2015, a 60-year-old patient presented in a local hospital in Mayotte with confusion, sweating and severe hypoglycemia (blood glucose as low as 20 mg/dl). He was suffering of...

Background: Thyroid autoimmunity (TAI) is the most important cause of hypothyroidism in the general population, and its prevalence is higher in women of subfertile couples.1 Women pregnant after an assisted reproductive technology (ART) with TAI carry a higher risk of a first trimester miscarriage rate compared to women without TAI. Several reasons could be underlying such as thyroid dysfunction, older age, an immune imbalance, and the presence of thyrotropin recept...

Background and Aims: Type 1 diabetes mellitus (T1DM) is caused by an autoimmune destruction of pancreatic beta cells, which renders patients insulin-dependent for life. The disease arises from a complex interaction among several genetic and environmental factors. To date, single nucleotide polymorphisms (SNPs) in >50 genes have been associated with T1DM, with HLA class II SNPs having the greatest impact on disease susceptibility. Other loci have minor effects on T...

Background and Aim: Type 1 diabetes mellitus (T1DM) is an autoimmune disease resulting from the complex interaction among multiple genes, environmental factors and the immune system. Genome-wide association studies identified ERBB3 (Erb-b2 receptor tyrosine kinase 3) gene as a main susceptibility locus for T1DM. This gene encodes a member of the family of intracellular receptors of protein tyrosine kinases, which activates multiple signaling pathways including PI3K-Ak...

Background and Aims: The transcription factor Gli-similar 3 (GLIS3) plays a key role in the development and maintenance of pancreatic beta-cells as well as in the regulation of Insulin gene expression in adults. Accordingly, genome-wide association studies identified GLIS3 as a susceptibility locus for type 1 diabetes mellitus (T1DM) and glucose metabolism traits. Therefore, the aim of this study was to investigate the association of the rs7020673 (G/C) and r...

Background and aims: Diabetic kidney disease (DKD) is a common microvascular complication that affects 40% of patients with diabetes mellitus (DM). Emerging evidence suggests a role for microRNAs (miRNAs) in the development of DKD. In this context, miR-15a-5p and miR-30e-5p have been shown to regulate the expression of the uncoupling protein 2, a mitochondrial protein that decreases reactive oxygen species (ROS) formation by mitochondria. Since ROS overproduction is a key cont...

Introduction: Only one case of hypophysitis secondary to Takayasu’s artheritis (TKA) has been described so far. We report the second case of a TKA presenting with a massive sellar and cerebrovascular infiltration.Clinical case: A 52 years-old female was referred to endocrine outpatient clinics after a brain MRI performed for a 2-year history of headaches, dizziness and general discomfort. Past medical history included hypertension and aspecific symp...
