Focus on Sarcoidosis
Risk of acute myocardial infarction in sarcoidosis: A population-based cohort study from SwedenDue 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.
Abnormal FeV1 and body mass index are associated with impaired cough-related quality of life in sarcoidosis patientsSarcoidosis is a granulomatous disease that mainly manifests within the lungs and may thereby impair lung function. Beyond and independently from organ impairment, sarcoidosis may affect quality of life which can be quantified by questionnaires. The Leicester Cough Questionnaire (LCQ) has been developed to assess cough-related quality of life. We analysed data from a prospectively collected cohort of sarcoidosis patients for validation of the German LCQ version. Our analyses demonstrated that LCQ values add additional information beyond routinely monitored parameters (e.g.
Current perspectives on the immunopathogenesis of sarcoidosisSarcoidosis is an inflammatory systemic disease that commonly affects the lungs or lymph nodes but can manifest in other organs. Herein, we review the latest evidence establishing how innate and adaptive immune responses contribute to the pathogenesis and clinical course of sarcoidosis. We discuss the possible role of microbial organisms as etiologic agents in sarcoidosis and the evidence supporting sarcoidosis as an autoimmune disease. We also discuss how animal and in vitro human models have advanced our understanding of the immunopathogenesis of sarcoidosis.
Clinical epidemiology of familial sarcoidosis: A systematic literature reviewAlthough the presence of familial sarcoidosis has been confirmed, clinical and epidemiological data on its characteristics are scattered and sometimes paradoxical. The objective of this review is to assess what is known on the clinical epidemiology of familial sarcoidosis, by combining data from early case reports with recent population based data; aiming to support in clinical decision making and providing information to patients.
