The results of a clinical study conducted over 20 years in a group of patients seen and treated at three large teaching hospitals in London shows that patients with sarcoidosis who experience an inflammatory optic neuropathy, or damage to the optic nerve due to inflammation, respond to treatment with corticosteroids.

Researchers at the National Research Institute of TB & Lung Diseases, in Poland, have developed a novel tool that helps identify patients with cardiac sarcoidosis via easily accessible and cost-effective tests. The study “Prevalence of cardiac sarcoidosis in white population: a case–control study: Proposal for a novel risk…

It is important to perform a lung biopsy when a change in chest X-ray is seen during pulmonary sarcoidosis monitoring, according to research conducted by Japanese scientists. This way, the rare possibility of complication with multicentric Castleman’s disease (MCD) can be ruled out or in the rare case it is diagnosed, appropriate treatment can be given to the patient.

In the study “Pembrolizumab-associated sarcoidosis,” researchers described the first case of sarcoidosis after a patient was treated with after Keytruda (pembrolizumab) to inhibit the programmed cell death-1 (PD-1) receptor. The study was published in the JAAD Case Reports journal. Keytruda is a humanized antibody that targets the PD-1…

When skin sarcoidosis is associated with pre-existing scars, it is called scar sarcoidosis. In a recent study, researchers at the Chungnam National University School of Medicine in Korea reported the case of a patient who developed scar sarcoidosis following pulsed dye laser treatment for a pre-existing scar. The study, “…

Sarcoidosis patients appear to have unusual energy production and transmethylation of proteins, as well as an abnormal gut microbiota, according to researchers at Wayne State University School of Medicine and colleagues, who compared the metabolites found in sarcoidosis patients with those of healthy people. The study, “Metabolomics connects aberrant bioenergetic, transmethylation,…

Cancer immunotherapy with Opdivo (nivolumab) and Yervoy (ipilimumab) may or may not trigger sarcoidosis in rare cases, a report from Yale University School of Medicine shows. The study, “Immune-related sarcoidosis observed in combination ipilimumab and nivolumab therapy,” published in the Journal of the American Academy of…

The study “Immunological Evidence for the Role of Mycobacteria in Sarcoidosis: A Meta-Analysis,” published recently in PLOS One, links some patients with sarcoidosis to the development of the disease and the presence of mycobacterium tuberculosis, which causes tuberculosis. Mycobacterium tuberculosis is the second leading cause of death by infectious disease, preceded only…

Psoriasiform lesions are a rare but established manifestation of sarcoidosis, in which psoriasis plaques are formed within sarcoidosis skin lesions. In a recent study, researchers at Thomas Jefferson University in Philadelphia and the University of Miami in Florida presented a case report of a patient with psoriasiform sarcoidosis, and discussed the…

Researchers at the University of Washington in Seattle identified numerous gene pathways that are altered in sarcoidosis, not only confirming the involvement of the innate immune system, but also demonstrating that systems for protein breakdown are activated in the disease. The study, “Sarcoidosis activates diverse transcriptional…
