Clinical, immunological, and genetic features in 938 patients with autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED): a systematic review.

: Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) is a rare inborn immune error characterized by a triad of chronic mucocutaneous candidiasis (CMC), hypoparathyroidism (HP), and adrenal insufficiency (ADI).: Literature search was conducted in PubMed, Web of Science, and Scopus databases using related keywords, and included studies were systematically evaluated.: We reviewed 938 APECED patients and the classic triad of APECED was detected in 57.3% (460 of 803) of patients. CMC (82.5%) was reported as the earliest, HP (84.2%) as the most prevalent, and ADI (72.2%) as the latest presentation within the classic triad. A broad spectrum of non-triad involvements has also been reported; mainly included ectodermal dystrophy (64.5%), infections (58.7%), gastrointestinal disorders (52.0%), gonadal failure (42.0%), neurologic involvements (36.4%), and ocular manifestations (34.3%). A significant positive correlation was detected between certain tissue-specific autoantibodies and particular manifestations including ADI and HP. Neutralizing autoantibodies were detected in at least 60.0% of patients. Nonsense and/or frameshift insertion-deletion mutations were detected in 73.8% of patients with CMC, 70.9% of patients with HP, and 74.6% of patients with primary ADI.: Besides penetrance diversity, our review revealed a diverse affected ethnicity (mainly from Italy followed by Finland and Ireland). APECED can initially present in adolescence as 5.2% of the patients were older than 18 years at the disease onset. According to the variety of clinical conditions, which in the majority of patients appear gradually over time, clinical management deserves a separate analysis.

The Effects of G2013 (α-L-guluronic Acid) in a Pentylenetetrazole-induced Kindling Animal Model of Epilepsy.

Innov Clin Neurosci 2020 Apr;17(4-6):9-12

Recent studies have reported observing antioxidant, anti-inflammatory, and anti-aging properties of α-L-Guluronic acid (G2013) in animal and human studies. It has been theorized that the antioxidant and anti-inflammatory properties of G2013 might be beneficial in epilepsy treatment. We sought to determine G2013's effects on epileptic activity in a kindling-induced animal model. Thirty rats were randomly divided evenly into three groups (10 rats in each group): 1) the G2013 group, which was treated with daily injections of G2013 for five days prior to the start of the study; during the 14-day study period, the G2013 rats were given single, daily injections of G2013 that preceded single daily injections of pentylenetetrazole (PTZ), a compound used to induce seizures; 2) the Normal group, which only received injections of saline during the 14-day study, with no seizure induction; and 3) the Control group, which received PTZ injections alone (for seizure induction) for the 14-day study period. The latency between seizure stages and duration of seizures in the G2013 and Control groups were measured using a 5-stage seizure severity scale. Brain samples were taken from all three groups and analyzed histopathologically for parenchymal and meningeal inflammatory cell infiltration. Additionally, the brain samples were analyzed to determine gene expression levels of interleukin-1-beta (IL-1β), IL-6, IL-10), tumor necrosis factor (TNF), chemokine (C-C motif) ligand-2 (CCL2), cyclooxygenase-2 (COX-2), and interferon-gamma (IFN-γ). The G2013 group demonstrated lower latency between Stages 2 and 5 seizures, with significantly longer mean duration of Stage 5 seizures, compared to the Control group. No significant differences were observed between the three groups histopathologically nor were there any observed differences in gene expression levels. Our results demonstrated a greater predisposition to PTZ-induced seizures in the rats who received G2013 and PTZ compared to rats who received PTZ alone, suggesting that G2013's epileptogenic property overshadows its anti-inflammatory effects when applied to a kindled animal model of study.

The effects of cadmium exposure in the induction of inflammation.

Immunopharmacol Immunotoxicol 2020 Feb 3;42(1):1-8. Epub 2019 Dec 3.

Department of Environmental Health Engineering, School of Public Health, Alborz University of Medical Sciences, Karaj, Iran.

Inflammation is a physiological process essential for maintaining homeostatic mechanisms in human, but however, exaggerated inflammatory responses are closely related to many chronic diseases. Cadmium (Cd) is a heavy metal with high toxicity when present in food, water and air has the potential of eliciting inflammatory reactions, with a major health risk to human. This review aimed to elucidate on the major routes of Cd exposure, the main organs affected by the exposure, the degree of toxicity as well as the roles of the toxic effects on the immune system which results to inflammatory responses. Immune modulation by Cd may cause serious adverse health effects in humans. Various studies have highlighted the ability of Cd as an environmental pollutant involved in the modulation of the innate, adaptive and mucosal immune responses in relations to the release of chemokine, gene expression, and susceptibility to microbial infections.
