Monogenic causes of autoimmunity provide key insights into the complex regulation of the immune system. We report a new monogenic cause of autoimmunity resulting from de novo germline activating STAT3 mutations in five individuals with a spectrum of early-onset autoimmune disease, including type 1 diabetes. These findings emphasize the critical role of STAT3 in autoimmune disease and contrast with the germline inactivating STAT3 mutations that result in hyper IgE syndrome.

Recently, avacopan has been approved for the treatment of ANCA-associated vasculitis (AAV). Avacopan is an inhibitor of the C5a-receptor, which plays an important role in chemotaxis and the amplification loop of inflammation in AAV. In the most recent, international guidelines avacopan is recommended as steroid-sparing agents for the management of AAV.

Why inhibiting calcineurin, a serine/threonine phosphatase, causes kidney fibrosis remains unknown. We performed single-nucleus RNA sequencing of the kidney from a chronic CNI nephrotoxicity mouse model and found an increased proportion of injured proximal tubule cells, which exhibited altered expression of genes associated with oxidative phosphorylation, cellular senescence and fibrosis.

Thyroid eye disease (TED) is a poorly understood autoimmune condition affecting the retroorbital tissue. Tissue inflammation, expansion, and fibrosis can potentially lead to debilitating sequelae such as vision loss, painful eye movement, proptosis, and eyelid retraction. Current treatment modalities for TED include systemic glucocorticoids, thioamides, methimazole, teprotumumab, beta-blockers, and radioactive iodine; however, it has been reported that up to 10%-20% of TED patients relapse after treatment withdrawal and 20%-30% are unresponsive to mainstay therapy for reasons that have yet to be more clearly elucidated.

Papulonodular mucinosis is a rare dermatological condition characterized by mucin deposition in the dermis, leading to the formation of papules and nodules that can occur with, or antedate, autoimmune connective tissue diseases. This case report presents a 67-year-old female with a chronic history of cutaneous mucinosis, which posed significant diagnostic challenges. Despite various treatments and extensive diagnostic workup, her condition evolved, highlighting the difficulties in diagnosing papulonodular mucinosis, especially in the absence of systemic lupus erythematosus and antinuclear antibody positivity.

The association between primary sclerosing cholangitis (PSC) and microscopic colitis (MC) has been explored in limited studies, suggesting potential shared pathophysiological mechanisms. This systematic review aimed to investigate this relationship by analyzing studies identified through comprehensive searches in PubMed, Embase, and the Cochrane Library. Two studies met the inclusion criteria: a case series of 12 patients and a case report, collectively analyzing 13 cases.
