ANCA-associated vasculitis (AAV) in the elderly: clinical presentation, treatment and outcomes
Tóm tắt
To explore treatment and outcomes in older patients with AAV. Retrospective review (1 year) of patients > 75 years with positive MPO/PR3 antibodies. Thirty-nine evaluable patients had new positive MPO/PR3 antibodies. Nine patients had AAV and two possible AAV (2M, 9F mean age 82 years). Nine patients had renal impairment and three died during their presenting admission, all having required dialysis ± plasma exchange. Non-survivors had higher average creatinine (442 vs 265 µmol/L) and more co-morbidities (2 or more co-morbidities vs 0 or 1). All patients deemed fit received treatment, one discontinued (infection). Survival in AAV was 46% at 1 year and 18% at 2 years. 1/3 of positive MPO/PR3 results were not acknowledged in case records by clinicians. Renal involvement is common in elderly patients with AAV. High creatinine, co-morbidity and need for dialysis are associated with a poorer prognosis. Mortality is high but survivors tolerate treatments well.
