One Case Of Microscopic Polyangiitis (MPA)Report And Analyse

[Objective] To study the microscopic polyangiitis (MPA) after the clinical characteristics and diagnosis and treatment, to strengthen the understanding of microscopic polyangiitis, to reduce the misdiagnosis and missed diagnosis.[Methods] Through the research analysis in our hospital emergency intensive care unit1case of microscopic polyangiitis clinical features and treatment, combined with literature analysis to its clinical manifestations,imaging features, diagnosis and treatment.[Discussion] Microscopic polyangiitis is a involving the small blood vessels of kidney, skin, lungs and other organs of systemic necrotizing vasculitis.30%-50%of MPA patients with lung involvement for the starting performance, early disease characterized by cough, expectoration, hemoptysis, fever and other symptoms, By serum immunological tests and lung tissue, renal biopsy definitize diagnosis.Giving glucocorticoid and immunosuppressive therapy, about90%of the microscopic polyangiitis patients can be improved more,75%of the patients can complete remission, but about30%of the patients with recurrence in1-2years, and mortality in severe patients more than50%, so it should be attention, regular follow-up.[Conclusion] Microscopic polyangiitis is a kind of autoimmune disease, the clinical manifestations of the lack of specificity, easily misdiagnosed or missed diagnosis, early right application of glucocorticoid and immunosuppressants can significantly improve the prognosis of patients.
