We sought to determine if there has been a change in the incidence of this disorder. Methods: Single-center, retrospective review. Results: Over the last 2 years, we have encountered a striking increase in the frequency of this disease in pediatric patients. All eight patients seen during this period had renal involvement and 5 patients rapidly progressed to end stage kidney disease. The prognosis was worse in younger patients, those with microscopic polyangiitis, and those with chronic kidney damage in the diagnostic renal biopsy. Conclusions: We report these observations to highlight this change in the epidemiology of ANCA-associated vasculitis and to promote earlier recognition and treatment of this severe form of glomerulonephritis.展开更多

In one third of the cases it is associated with other autoimmune disorders, mostly with anti-neutrophil cytoplasmic antibody(ANCA) associated vasculitis(AAV). We report three cases of RP with p-ANCA positive AAV. In the first patient RP developed 1.5 years after the onset of AAV. In the others the signs of RP were present before the onset of severe crescent glomerulonephritis. Patients responded well on steroid and cyclophosphamide. In dialysis dependent cases plasmapheresis was also used successfully. During the 2 and 1.5 years of follow up, they were symptom-free, and had stable glomerular filtration rate. The first patient died after four years of follow-up due to the complications of sudden unset pancytopenia,which raises the possibility of associated hemophagocytic syndrome. In the setting of RP or AAV physicians should always be aware of the possibility of sudden or insidious appearance of the other disease.展开更多
