ABSTRACT
Statins competitively inhibit the activity of HMGCR (3-hydroxy-3-methylglutaryl coenzyme A reductase), which is a key enzyme in cholesterol synthesis. These are effective drugs for the management of cardiovascular disease and are generally well tolerated but several side effects have been reported. Muscular adverse symptoms are various and, rarely, statin exposure may lead to authentic immune-mediated necrotizing myopathy (IMNM), namely anti-HMGCR myopathy. However, cases of IMNM associated with cancer have been described. We discuss herein a case of IMNM in a patient with breast cancer previously exposed to statins and with the presence of anti-Th/To antibodies without clinical correlation.
ABSTRACT
Adult-onset Still's disease (AOSD) is a rare auto-inflammatory syndrome of unknown etiology. Basedow's disease is a common cause of auto-immune hyperthyroidism. Collagenous colitis (CC) is a form of microscopic colitis (MC) affecting predominantly young women. While the etiology of the disease remains unclear, some studies suggest the role of auto-immunity. The association between AOSD and Basedow's disease has been reported in previous cases, suggesting auto-inflammation as a potential trigger of relapsing thyroid dysfunction. Although the co-existence of AOSD with inflammatory gastrointestinal disorders such as Crohn's disease and ulcerative colitis has also been described, we did not find any correlation with MC in the literature. We here describe the case of a woman having AOSD associated with Basedow's disease and CC.
ABSTRACT
In Granulomatosis with polyangiitis (GPA), involvement of the peripheral nervous system is frequent but its occurrence as an initial presentation is unusual. This case highlights the importance of this occurrence to permit an early diagnosis. Moreover, GPA started after a coronavirus disease 2019 infection and could have been induced by this.
