AAV is a multi-organ disease, which can be complex and may vary from person to person. Types of AAV include granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). This variety can make management challenging. Comorbidities, an individual’s history, toxicities, medication availability and cost, and patient preferences should all be considered in the process of informed decision making.

Metformin may help cut the risk of osteoarthritis (OA) in those with type 2 diabetes, researchers reported.

In a retrospective cohort study of nearly 21,000 adults with diabetes, those who were taking metformin saw a 24% lower risk for developing OA compared with those taking a sulfonylurea (adjusted hazard ratio [aHR] 0.76, 95% CI 0.68-0.85), according to Matthew Baker, MD, MS, of Stanford University in Palo Alto, California, and colleagues.
