Could CGRP mAbs for migraine trigger rheumatoid arthritis? Insights from a case report.

Background: Case reports suggest that calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) may trigger inflammatory flares in patients with autoimmune diseases.

Case Description: A 56-year-old woman with a history of severe migraines, experienced improvement in migraine frequency and intensity after starting fremanezumab 225 mg monthly. However, three months into treatment, she developed symmetric inflammatory polyarthralgias.

When Standing Takes Your Breath Away: A Clinical Case of Platypnea-Orthodeoxia Syndrome.

Platypnea-orthodeoxia syndrome (POS) is characterized by dyspnea due to a marked fall in blood oxygen saturation while assuming standing or sitting positions. It is a rare condition with an unknown prevalence. The triggering role may remain unclear in a considerable number of patients.

Drugs and ANCA - an atypical association.

Eosinophilic vasculitis is a rare condition due to vascular damage and infiltration of eosinophils into tissues. Antineutrophil cytoplasmic antibody (ANCA), like perinuclear ANCA (p-ANCA), is common in the context of systemic vasculitis, but its association with illicit drug use is unusual. This case report showcases a distinctive scenario featuring a positive pANCA, prompting a meticulous examination of the interplay between vasculitic manifestations and drug abuse.

7T MRI detects widespread brain iron deposition in neuroferritinopathy.

Neuroferritinopathy is a disorder of neurodegeneration with brain iron accumulation that has no proven disease-modifying treatments. Clinical trials require biomarkers of iron deposition. We examined brain iron accumulation in one presymptomatic FTL mutation carrier, two individuals with neuroferritinopathy and one healthy control using ultra-high-field 7T MRI.
