Peculiarities of in-Stent Thrombosis and Restenosis in Coronary Arteries Post-COVID-19: A Systematic Review of Clinical Cases and Case Series.

Background: One of the most serious complications of coronary artery stenting is restenosis and in-stent thrombosis; their prevalence can reach 20-25%. Stent thrombosis can be acute (up to 24 hours), subacute (24 hours to 30 days), late (30 days to 1 year), and very late (> 1 year after previous stenting). In the patients with COVID-19 in intensive care units, the proportion of those with elevated troponin levels reached 25%.

Assessment of the Predictive Ability of the Neutrophil-to-Lymphocyte Ratio in Patients with In-Stent Restenosis after COVID-19.

Background: The neutrophil-to-lymphocyte ratio (NLR) is an independent predictor of the severity of coronary heart disease and COVID-19. This study aims to assess the predictive ability of the NLR in patients with in-stent restenosis after COVID-19.

Materials And Methods: a cross-sectional study included 931 patients who underwent repeated myocardial revascularization between May 2020 and May 2023.

Autoimmune polyendocrine syndrome type 1: Clinical manifestations, pathogenetic features, and management approach.

Autoimmune polyendocrine syndrome type 1 (APS-1) is an autosomal recessive hereditary pathology that develops with endocrine and non-endocrine manifestations in childhood. The classic triad of APS-1 includes chronic candidiasis of the skin and mucous membranes, adrenal insufficiency, and hypoparathyroidism. APS-1 is often accompanied by hypogonadism, type 1 diabetes, autoimmune thyroiditis, vitiligo, alopecia, asplenia, pneumonitis, gastritis, pernicious anemia, and intestinal dysfunction, nephritis, and hepatitis.
