Purpose: Although there is ample data about the prevalence of diabetes in the Middle East, little is known about the prevalence and features of autoimmune diabetes in this region. The aim of this study was to investigate the prevalence and metabolic characteristics of latent autoimmune diabetes in adults (LADA) amongst Yemeni Type 2 DM patients.
Patients And Methods: In this cross-section study, 270 Type 2 DM patients aged 30-70 years were recruited from the National Diabetes Center, Al-Thowra Hospital, Sana'a city, during the period November 2015 to August 2016. All Type 2 DM patients were diagnosed within 5 years and who did not require insulin for a minimum of 6 months following diagnosis. Levels of glutamic acid decarboxylase autoantibodies (GADA) were measured in all patients, and LADA was diagnosed in patients testing positive for anti-GAD antibodies. Further, biochemical analysis was carried out including fasting blood glucose (FBG), glycated haemoglobin (HbA1c), insulin, and lipid profile. Insulin resistance (HOMA-IR) and β-cell function (HOMA-β) were calculated.
Results: The prevalence of LADA, as defined by GADA-positive, amongst patient with Type 2 DM was 4.4%; with no significant difference in the prevalence between male (5.8%) and female (3.4%). LADA patients were younger than GADA-negative Type 2 DM. Body mass index, waist circumference, insulin and HOMA-β were significantly lower in LADA patients, whereas triglyceride, cholesterol, HDL-c and HOMA-IR were non-significantly lower with respect to Type 2 DM. In contrast, FBG and HbA1c were significantly higher in LADA patients. Moreover, the prevalence of metabolic syndrome was significantly lower in LADA as compared with Type 2 DM. Only 2 out of the 12 GADA-positive (16.7%) were on insulin treatment at the time of the study.
Conclusion: The prevalence of LADA in Yemeni Type 2 DM is lower than many of those reported in the literature, with no gender preference. Metabolic syndrome was significantly lower in LADA patients. Patients with LADA share insulin resistance with Type 2 DM but display a more severe defect in β-cell function, thus highlighting the importance of an early diagnosis of LADA, to correctly treat LADA patients, allowing safe and effective therapies.

Increasing evidence shows that pathogenic T cells in type 1 diabetes (T1D) that may have evaded negative selection recognize post-translational modified (PTM) epitopes of self-antigens. We have investigated the profiles of autoantibodies specifically targeting the deamidated epitopes of insulinoma antigen-2 extracellular domain (IA-2ec) to explore their relationship with T1D development. We compared the characteristics of autoantibodies targeting the IA-2ec Q>E epitopes (PTM IA-2ecA) as well as those targeting the IA-2ec unmodified epitopes (IA-2ecA) in participants across different stages of T1D development and in individuals with other types of diabetes and other kinds of autoimmunity.

Introduction: Type 1 diabetes involves immune-mediated destruction of insulin-producing beta cells, with eosinophils potentially playing a significant role. Recent studies suggest that leukotriene inhibition might influence this process. This case report presents a novel observation of montelukast, a leukotriene receptor antagonist, reducing insulin requirements in a patient with Latent Autoimmune Diabetes in Adults (LADA).

Latent autoimmune diabetes of adults (LADA) is the most prevalent form of autoimmune diabetes (AI-D) in adulthood; however, its accurate diagnosis and optimal treatment remain challenging. Vitamin D deficiency (VDD) is commonly observed in LADA patients, while increased vitamin D exposure through supplementation and dietary intake is associated with a reduced incidence of LADA. Although limited, case reports, case-control studies, and randomized clinical trials have examined the effects of vitamin D supplementation-alone or combined with dipeptidyl peptidase-4 inhibitors (DPP4-is)-on glucose regulation, residual β-cell function, and glutamic acid decarboxylase antibody (GADA65) levels.

Aims: Bidirectional detrimental relationships between COVID-19 infection and diabetes have been described globally. However, new-onset diabetes in adults and its follow-up during the pandemic have not been sufficiently investigated. In this study, new-onset autoimmune and type 2 diabetes cases during the pandemic were compared to those before the pandemic, and the clinical course of new-onset diabetes during the pandemic was examined.

Article Synopsis
- The pilot study focused on the presence of micronuclei (MN) and other nuclear abnormalities in oral mucosa cells from patients with type I, II, and LADA diabetes, comparing results to healthy individuals.
- Cytogenetic analysis indicated that diabetes patients had significantly higher levels of MN, particularly in type I and LADA groups, suggesting potential cytotoxic and genotoxic effects of the disease.
- There was a strong correlation found between MN levels, blood glucose concentration, and glycosylated hemoglobin, highlighting the impact of diabetes on cellular health.
