Pak J Med Sci 2024; 40:1083-1086. [PMID: 38952492 PMCID: PMC11190383 DOI: 10.12669/pjms.40.6.7794] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 07/17/2023] [Accepted: 02/14/2024] [Indexed: 07/03/2024] Open
Abstract
Background and Objective The autoimmune mechanism in T1DM causes gradual loss of pancreatic β-cell, which progresses to hyperglycemia and ultimate reliance on consistent insulin therapy. T1DM has been the commonest type of diabetes in children and this study will help in refining indulgent towards the problem and its pathophysiology in our people. The objective was to find out the prevalence of C-peptide and antibody levels (anti GAD, ICA, IAA and IA2) in children and adolescents of Pakistan with T1DM. Methods We conducted this cross-sectional study at Department of Pediatric Endocrinology, National Institute of Child Health, Karachi between August 2019 to February 2020 and included 98 children who had T1DM for more than one month. Subjects whose GFR was <30ml/min were omitted from the study. Among those registered subjects, C-peptide, human islet cell antibody (ICA), insulin auto antibodies (IAA) and anti-glutamic acid decarboxylase were assessed. Demographical and laboratorial facts were noted on a pre-constructed proforma. Results There were 77(78.3%) cases who had level of C-peptide <0.8 and anti-GAD was found in 47(48%) subjects. 35(35.7%) cases found positive for IA2 .and 7(7.1%) patients had insulin auto antibodies positive while ICA was negative in total 98(100%) subjects. Conclusion Children with T1 DM possessed increased levels of anti-GAD antibodies, insulin autoantibodies and anti (IA2) but islet cells antibodies were negligible in our population when checked at a point of time. C-peptide may be normal in some, but its level declines with long duration of diabetes in children.

Abstract
OBJECTIVE Zinc transporter 8 autoantibodies (ZNt8A) are 1 of the 4 main autoantibodies used for the diagnosis of type 1 diabetes (T1D), with glutamic acid decarboxylase autoantibodies (GADA), islet antigen-2 autoantibodies (IA-2A), and insulin autoantibodies (IAA). The objective of this study is to evaluate the diagnostic efficiency of these autoantibodies for the diagnosis of T1D in pediatric patients. METHODS A retrospective analysis of patients under 16 years of age with suspected T1D was made between June 2020 and January 2021. A total of 80 patients were included in the study, with 1 sample per patient. Subjects were classified according to diagnosis. RESULTS Of the subjects included in the study, 50 developed T1D. The diagnostic efficacy was IA-2A (cutoff ≥ 28 U/L) sensitivity 0.26 (95% CI: 0.14-0.38) and specificity 0.97 (95% CI: 0.79-1.0); GADA (cutoff ≥ 17 U/mL) sensitivity 0.40 (95% CI: 0.26-0.54) and specificity 0.87 (95% CI: 0.75-0.99); ZnT8A (cut off ≥ 15 U/L) sensitivity 0.62 (95% CI: 0.49-0.75) and specificity 0.97 (95% CI: 0.90-1.0). ZnT8A obtained the most significantly global diagnostic accuracy (0.75), and GADA with ZnT8A showed the highest correlation. CONCLUSION The results obtained indicate a higher efficiency of anti-ZnT8 autoantibodies for the diagnosis of T1D in pediatric patients. Clinical efficiency of diabetic autoantibodies is method and assay dependent and influences combined diagnostic strategies.

Abstract
BACKGROUND Immunotherapy, specifically the use of checkpoint inhibitors such as pembrolizumab, has become an important tool in personalized cancer therapy. These inhibitors target proteins on T-cells that regulate the immune response against tumor cells. Pembrolizumab, which targets the programmed cell death 1 receptor on T-cells, has been approved for the treatment of metastatic melanoma and non-small cell lung cancer. However, it can also lead to immune-related side effects, including pneumonitis, colitis, thyroid abnormalities, and rare cases of type 1 diabetes. CASE SUMMARY The case presented involves an adult patient in 30s with breast cancer who developed hyperglycemia after receiving pembrolizumab treatment. The patient was diagnosed with diabetic ketoacidosis and further investigations were performed to evaluate for new-onset type 1 diabetes. The patient had a history of hypothyroidism and a family history of breast cancer. Treatment for diabetic ketoacidosis was initiated, and the patient was discharged for close follow-up with an endocrinologist. CONCLUSION This literature review highlights the occurrence of diabetic ketoacidosis and new-onset type 1 diabetes in patients receiving pembrolizumab treatment for different types of cancer. Overall, the article emphasizes the therapeutic benefits of immunotherapy in cancer treatment, particularly pembrolizumab, while also highlighting the potential side effect of immune-related diabetes that can occur in a small percentage of patients. Here we present a case where pembrolizumab lead to development of diabetes after a few cycles highlighting one of the rare yet a serious toxicity of the drug.

Abstract
Background Diabetes mellitus type 1 (T1D) is an autoimmune organ-specific disease with a wide range of clinical manifestations, in which the β cells of the pancreatic islets of Langerhans are destroyed by the action of autoreactive T lymphocytes and the formation of autoantibodies against β cell components. Among used serological markers of T1D, anti-glutamic acid decarboxylase antibodies (GAD65), anti-tyrosine phosphatase antibodies (IA2), islet cell antibodies (ICA), insulin autoantibodies (IAA) and anti-zinc transporter antibodies (Zn-T8) are of great significance. Objective This study aimed to analyze presence of type 1 diabetes-related autoantibodies (GAD65, IA2, ICA, IAA and Zn-T8 and effects of age and gender on their occurrence in pediatric population. Methods Sixty seven (N=67) T1D pediatric patients were included in the study. The levels of immunological parameters such as anti-glutamic acid decarboxylase antibodies (GAD-Ab), anti-tyrosine phosphatase antibodies (IA2-Ab), islet cell antibodies (ICA) and insulin autoantibodies (IAA) were determined by chemiluminescence immunoassay (CLIA) and anti-zinc transporter antibodies (Zn-T8-Ab) were determined by enzyme-linked immunosorbent assay (ELISA). For statistical analysis, we used SPSS statistical program. Results Our study revealed that among 67 patients with T1D (40 male and 27 female), with an average age of 12,1±3,9 years. The average age of diabetes diagnosis was 6,15±3,29 years. 24 (35,8%) cases were positive for GAD65, 15 (22,4%) for ICA, 34 (50,7%) for IAA, 16 (23,9%) for IA2 and 36 (53,7%) for Zn-T8. The largest number of patients had single positive antibody, the most dominated among them was IAA dominated (40,9%), then Zn-T8 (31,8%). According to Spearman correlation test Zn-transporter shows a significant positive correlation with age of the participants (p=0.027) and disease duration (p=0.006). Anti IA2 shows significant negative correlation with HbA1c (p=0.043). Zn-transporter is associated with patients age and duration of T1D. Conclusion In most cases, patients with T1D are positive for at least one of the specific autoantibodies. Zn-T8 is the most frequently detected and is an important serological marker of type 1 diabetes mellitus. Gender effects on autoantibodies seems to be insignificant, while age alongside disease duration shows important effects.

Abstract
OBJECTIVE The aim of this study was to investigate the role of cytokines in children with T1D living in Saudi Arabia and their correlation with disease duration and autoimmune antibody markers. METHODS A case-control study was conducted in the endocrine clinic of King Abdullah Specialized Children's Hospital in Riyadh. A total of 274 T1D and healthy control children were enrolled in the study. 5 mL of venous blood samples were collected in the morning after 9 to 12 h of fasting in BD Vacutainer® EDTA tubes and centrifuged at 250g for 15 min at. Plasma was then stored at -20°C for detection of anti-islet, anti-GAD antibodies (Abs), and C-peptide using commercial ELISA kits from Thermo Fisher Scientific. The levels of cytokines were measured using commercial sandwich ELISA kits from Abcam. RESULTS Median differences in cytokine levels (IFN-γ, TNF-α, IL-1β, IL-2, IL-4, IL-6, IL-10, IL-13, IL-18, IL-21, IL-35, and IL-37) were significantly higher in T1D patients compared with healthy controls (p-value < .001). Spearman's Rho correlation indicated that TNFα, IL-1β, IL-4, IL-10, IL-13, and IL-21 correlated significantly with T1D Abs (p-value = .01). HbA1C correlated negatively with IL-35 and IL-37, and positively with IL-18 (p-value = .01). Linear regression analysis showed a significant increase in anti-glutamic acid antibodies (GAD) in patients with >3 years of T1D duration. CONCLUSION Autoantibodies remained positive at high levels in our patients over a 3-year duration of the disease and correlated with specific cytokines. The clear correlations with disease duration and profile of specific cytokines could be targets for future therapeutic interventions.

The prevalence of diabetes and thyroid related autoantibodies in Sri Lankan children with type 1 diabetes and their unaffected siblings - The utility of a new screening assay. Front Endocrinol (Lausanne) 2023; 14:1028285. [PMID: 36814577 PMCID: PMC9939822 DOI: 10.3389/fendo.2023.1028285] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 01/16/2023] [Indexed: 02/09/2023] Open
Abstract
BACKGROUND There is limited information about diabetes and thyroid related autoantibodies in children with type 1 diabetes (T1D) or their siblings in Sri Lanka. OBJECTIVES To assess in T1D children and their unaffected siblings the prevalence of autoantibodies to (1) glutamic acid decarboxylase (GADA), insulinoma associated antigen-2 (IA-2A) and zinc transporter 8 (ZnT8A) using 3 Screen ICA™ (3-Screen) and individual ELISA assays; (2) insulin (IAA); and (3) thyroid peroxidase (TPOA), thyroglobulin (TgA) and the TSH receptor (TSHRA). METHODS We selected - (a) consecutive T1D children, and (b) their unaffected siblings of both sexes, from the T1D Registry at Lady Ridgeway Hospital, Colombo. RESULTS The median age (IQR) of 235 T1D children and 252 unaffected siblings was 11 (8.4, 13.2) and 9 (5.4, 14.9) years respectively, and the duration of T1D was 23 (7, 54) months. (1) T1D children (a) 79.1% were 3-Screen positive; (b) all 3-Screen positives were individual antibody positive (GADA in 74%; IA-2A 31.1%; ZnT8A 38.7%); (c) and were younger (p=0.01 vs 3-Screen negatives); (d) multiple autoantibodies were present in 45.1%; (e) IA-2A (p=0.002) and ZnT8A (p=0.006) prevalence decreased with T1D duration. (f) TPOA and TgA prevalence was higher in T1D children compared to unaffected siblings (28%, p=0.001 and 31%, p=0.004, respectively). (2) Unaffected siblings (a) 6.3% were 3-Screen positive (p=0.001 vs T1D), and 2.4% were positive for IAA; (b) four subjects had two diabetes related autoantibodies, one of whom developed dysglycaemia during follow-up. CONCLUSIONS The 3-Screen assay, used for the first time in Sri Lankan T1D children and their siblings as a screening tool, shows a high prevalence of T1D related Abs with a high correlation with individual assays, and is also a helpful tool in screening unaffected siblings for future T1D risk. The higher prevalence of thyroid autoantibodies in T1D children is consistent with polyglandular autoimmunity.

Abstract
Objectives Type 1 diabetes mellitus (T1DM) is a well-known autoimmune disease, characterized by β-cell destruction in pancreas islet cells, which results insulin deficiency and subsequent hyperglycemic sequelae. While there is screening for type 2 DM that leads to better glycemic control and outcome, the majority of T1DM patients are diagnosed when much of the pancreatic cells and their function are disturbed. The aim of this article is to present an overview of the effective factors in the positivity of Glutamic acid decarboxylase antibody )GADA( and identifying the high-risk individuals for T1DM. Methods We searched English literature available at National Library of Medicine via PubMed, and Google Scholar through December 2020. Finally, 79 papers have been included in the study. Studies were summarized based on the number of positive autoantibodies and onset of T1DM over time and GADA correlation with different variables. Conclusions GADA is an easy marker to measure that can be detected many months prior to the clinical presentation and remains positive even after early childhood.

Abstract
PURPOSE Anti-CD20 therapy delays type 1 diabetes mellitus (T1DM) progression in both nonobese diabetic (NOD) mice and new-onset patients. The mechanism is not completely defined. This study aimed to investigate the effects of anti-CD20 therapy on T helper 17 (Th17) cells and regulatory T cells (Tregs) in NOD mice. The role of B cell depletion in T1DM development was also examined. METHODS NOD mice were randomly divided into two groups. The mice in the experimental group were treated with an anti-CD20 antibody, while the control mice were treated with an isotype-matched control antibody. After treatment, islet morphology and inflammation, Th17 and Treg cell frequencies in the pancreas and spleen, serum cytokine and anti-glutamic acid decarboxylase (GAD) antibody levels, interleukin (IL)-17A levels in the pancreas and spleen, insulin expression in islet cells and islet β cell function were measured. RESULTS Decreased blood glucose and increased insulin secretion were found in the exprimental group compared with the CON group. A lower islet inflammation score was also found in the experimental group. Decreased Th17 cell and IL-17A levels and augmented Treg cell levels were found in the spleen and pancreas after anti-CD20 treatment. The serum levels of B cell activating factor (BAFF), IL-17A, IL-17F, IL-23 and anti-GAD autoantibodies were decreased in the experimental group, while higher serum levels of IL-10 and transforming growth factor (TGF)-β were found. CONCLUSION Anti-CD20 therapy might have some beneficial effects that improve β cell function by relieving islet inflammation through regulation of Th17/Treg cells and the proinflammatory/anti-inflammatory balance.

Abstract
BACKGROUND Lipoatrophy (LA), a rare skin complication in patients with type 1 diabetes (T1D), has decreased dramatically over the past decades due to the use of human purified insulin preparations. METHODS We collected data from the records of T1D patients with LA. Types of insulin and insulin regimen, presence of eosinophilia, anti-insulin (IAA), anti-GAD, anti-IA2 autoantibodies, other autoimmune disorders, site of atrophy and its relationship to catheter, HbA1c at LA onset and after resolution, and different treatment modalities (i.e., change of insulin type or site, sodium cromoglycate (SCG) cream, cortisone cream or percutaneous injections, and laser treatment) were recorded. RESULTS Thirteen out of 1200 T1D subjects (1%) presented with LA. The majority were on insulin pump using rapid-acting analogs. Twelve out of 13 patients had changed the type of insulin, and most of them had switched injection sites. Ten out of 13 patients used SCG cream and 7/10 showed complete/partial improvement. One patient used dexamethasone injection with improvement. Five patients showed self-improvement. In 3/7 patients who were receiving SCG, treatment was combined with change of insulin type (glulisine); however, in 1/3, the result should be attributed to concomitant laser treatment. In 4/7 patients, there was a clear, beneficial effect of SCG. In 1/4 with partial resolution of LA, laser treatment was used after SCG, which further improved the result. CONCLUSIONS LA is a rare skin complication seen even today with the use of insulin analogs. SCG alone or combined with change of insulin type seems to be the most effective treatment. Laser treatment is a promising new therapy.

Abstract
BACKGROUND AND AIMS Autoimmune thyroid dysfunction (AITD) is a significant autoimmune disorder affecting the population across age groups. The clustering of autoimmune diseases tends to occur within the same patients and families. Thus, this study aimed to determine the association of Type 1 diabetes and other autoimmune ailments in patients with autoimmune thyroid disorders. METHODS We performed a cross-sectional study, evaluating 500 subjects with a diagnosis of AITD (130 with Graves' disease; 370 with Hashimoto's thyroiditis) on presentation to our tertiary care centre to ascertain the prevalence of associated autoimmune disorders. RESULTS The frequency of Type 1 diabetes and other autoimmune disorders was 18.5% in Graves' disease and 27.8% in Hashimoto's thyroiditis patients. Coeliac disease (8.8%) (found in 6.9% of Graves' disease and 9.5% of Hashimoto's thyroiditis patients) and type 1 diabetes (7.8%) (found in 3.1% of Graves' disease and 9.5% of Hashimoto's thyroiditis patients) were the most common coexisting autoimmune disorders. Rheumatoid arthritis was the most common non-endocrine autoimmunity (2.8%). Female sex and duration of AITD more than five years were associated with increased odds of associated autoimmune disorders. CONCLUSION A high prevalence of associated autoimmune disorders was observed in subjects with autoimmune thyroid dysfunction. We suggest the patients who remain symptomatic and those who develop other symptoms even with appropriate treatment undergo screening for associated autoimmune disorders, thus preventing a delay in diagnosis.

Abstract
Both celiac disease (CD) and type 1 diabetes (T1D) are autoimmune diseases resulting from a complex interplay between genetic susceptibility and environmental factors.
