Focus on Sarcoidosis
Risk of acute myocardial infarction in sarcoidosis: A population-based cohort study from Sweden
Due to conflicting findings in previous studies, it remains unclear whether individuals with sarcoidosis are at a higher relative risk of acute myocardial infarction. In this cohort study, individuals with sarcoidosis and matched general population comparators were followed for acute myocardial infarction in Swedish nationwide registers. A small (20%) risk increase associated with sarcoidosis was identified, which did not markedly vary by age at diagnosis, sex, treatment status around diagnosis, and time since diagnosis.Sarcoidosis: A nationwide registry-based study of incidence, prevalence and diagnostic work-up
The primary objective was to evaluate the prevalence and incidence of sarcoidosis, and secondly, to evaluate differences in incidence by age at diagnosis, gender, region, calendar year and treatment and to evaluate sarcoidosis-related diagnostic work-up.HLA-DRB1 alleles associate with hypercalcemia in sarcoidosis
The mechanisms behind and which patients are at risk of developing sarcoidosis associated hypercalcemia (SAHC) have not been addressed. Different human leukocyte antigen (HLA) alleles associate with disease phenotypes in sarcoidosis. Insights into associations between HLA alleles, clinical phenotype and calcium levels may provide clues to mechanisms behind SAHC and help monitoring patients at risk for SAHC.High expression of mTOR signaling in granulomatous lesions is not predictive for the clinical course of sarcoidosis
Sarcoidosis is a systemic granulomatous disease with a variable clinical presentation and disease course. There is still no reliable biomarker available, which assists in the diagnosis or prediction of the clinical course. According to a murine model, the expression level of the metabolic checkpoint kinase mechanistic target of Rapamycin complex 1 (mTORC1) in granulomas of sarcoidosis patients may be used as a clinical biomarker.
