Abstract

INTRODUCTION - Microscopic polyangiitis (MPA) is a systemic autoimmun disease characterized by necrotizing small vasculitis. MPA belongs to the ANCA-associated vasculitides. The disease can affect many of the body's organ systems. Major organs involved are kidneys, skin, peripheral nerves and lungs. In addition, generalized symptoms such as fever and weight loss are very common. CASE REPORT - In January 2013 a 56-year old woman presented with weight loss, lower leg numbness, walking difficulty and petechiae on the lower legs. One month later, laboratory examinations showed progressive kidney dysfunction, anemia, hypersedimentation and elevated C reactive protein level, but further tests and investigations for potential bacterial infection and tumors were all negative. In sum, clinical signs and symptoms suggested systemic vasculitis, which was proved by the kidney biopsy and ENG examination. From these findings, microscopic polyangiitis was diagnosed with polyneuropathy and glomerulonephritis. The patient was a Hepatitis B (HBV) virus carrier, which can be provoking factor for vasculitis. Corticosteroid and six treatment cycles of intravenous pulse cyclophosphamide were performed for induction of remission. After treatment her symptoms improved and kidney function was normalized. Antiviral treatment was started because of HBV reactivation in October 2013. As a new manifestation of MPA, pulmonary symptoms were appeared in November 2013 and the patient was treated with synchronization of plasmapheresis and pulse cyclophosphamide with good clinical effectivity. Now, she is treated with methotrexate as immunosuppressive treatment and control examinations indicate the remission of the disease with proper renal function. CONCLUSION - We draw attention to a rare case of vasculitis and underline the importance of both the early diagnosis and the early and effective immunosuppressive therapy. Peripheral neuropathy may occur as a result of having systemic vasculitis. Nevertheless, the exploration and elimination of provoking factors are also must be part of the management and the regular follow-up is essential to recognize the disease relapses, thus avoid permanent organ damage.
