Vasculitis for the internist: focus on ANCA-associated vasculitis

Area of Science:

• Rheumatology
• Internal Medicine
• Immunology

Background:

• Vasculitides encompass diverse diseases affecting arteries, capillaries, and veins.
• Antineutrophil cytoplasm antibody-associated vasculitides (AAVs) are a subgroup of systemic necrotizing small-vessel vasculitis.
• Key AAVs include granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis.

Purpose of the Study:

• To provide internists with a focused review of AAVs.
• To address critical aspects for managing AAV patients.
• To highlight recent advancements and challenges in AAV care.

Main Methods:

• Literature review focusing on AAV classification, diagnosis, treatment, and follow-up.
• Synthesis of current knowledge relevant to internal medicine practice.
• Emphasis on practical considerations for internists.

Main Results:

• AAVs present diagnostic challenges requiring careful evaluation.
• Novel therapeutic strategies are emerging for AAV management.
• Effective follow-up is crucial for mitigating morbidity and mortality.

Conclusions:

• AAVs are significant conditions managed by internists.
• Understanding classification, diagnostic nuances, and treatment updates is essential.
• Proactive management and follow-up improve patient prognoses in AAVs.
