ConclusionsWith the experience we gained from our recent studies, we think that miRNA-204 may be a significant biomarker in autoimmune diseases. Our study is the first study between IgAV and miRNAs in children. More studies are needed to reveal this relationship.Key Points•This is the first paper to show the relationship between miRNAs and childhood IgAV.•It will provide a new perspective to evaluate the pathogenesis of the disease.

Authors: Bonometti R, Sacchi MC, Stobbione P, Lauritano EC, Tamiazzo S, Marchegiani A, Novara E, Molinaro E, Benedetti I, Massone L, Bellora A, Boverio R Abstract Coronavirus disease 2019 (COVID-19) is a respiratory tract infection caused by a newly emergent coronavirus, SARS-CoV-2. The acute phase may be followed by a second phase actually not yet completely understood but probably associated to an autoimmune activation. At the moment is not possible to clearly define an association between immunological findings and pathological symptoms, however, this case report describes the case of a patient who following COV...

A 66-year-old man with a history of non–small cell lung cancer treated with nivolumab underwent contrast-enhanced CT and FDG PET/CT. No recurrence was demonstrated; however, soft-tissue thickening that showed delayed contrast enhancement and FDG uptake was detected around an abdominal aortic aneurysm. After discontinuation of nivolumab, the periaortic lesion disappeared within 2 months, indicating nivolumab-induced periaortitis. Immune checkpoint inhibitors such as nivolumab can cause vasculitis and periaortitis, a potentially fatal condition, as immune-related adverse events. The underlying aortic aneurysm may have ...

Pembrolizumab, a programmed cell death protein 1 (PD1) inhibitor, has been known to be associated with several adverse reactions, including immune related adverse events. In less than one percent of patients, PD1 inhibitors have been linked to the development of connective tissue disease. Patients with previously known connective tissue disease are hypothesized to be at increased risk of flares in as many as 40% of cases. A 70-year-old man with a past medical history significant for rheumatoid arthritis in remission and stage IV lung adenocarcinoma presented to the dermatology clinic after one cycle of nivolumab and eight ...

Lepromatous leprosy is associated with a high bacillary load and poor cellular immune response. Early dermatologic manifestations include erythematous macules, papules, nodules, and plaques with a symmetrical distribution. Leprosy also shows two major reaction states including type I (reversal reaction) and type II (vasculitis). These reactions are usually seen in some patients who are undergoing treatment. Herein, we report an interesting patient with lepromatous leprosy who presented with skin lesions of type II reaction without receiving any anti-leprosy treatment and surprisingly showed a type I reaction eight months a...
