We report a case of methicillin-resistant Staphylococcus aureus (MRSA)-associated glomerulonephritis treated with antibiotic therapy. A 67-year-old man was admitted to our hospital because of proteinuria, hematuria, purpura, and high fever one month after a graft replacement of an abdominal aortic aneurysm. MRSA was detected in specimens of his blood, sputum, and joint fluid. Before his operation, he had shown no renal abnormalities. He presented with a rapid deterioration of renal function following MRSA infection. Maximum level of proteinuria was 1.5 g/day, serum creatinine (Cr) was 3.5 mg/dl, and blood urea nitrogen was 57 mg/dl. Renal biopsy revealed necrotizing crescentic glomerulonephritis. Immunofluorescence examination showed IgA and C3 deposits. Clinical and pathological examinations showed the typical features of MRSA-associated glomerulonephritis. Vancomycin and fosfomycin were administered intravenously. The serum level of C-reactive protein fell from 22.0 mg/dl to 0.1 mg/dl. Proteinuria also decreased and the patient's renal function improved in parallel with the decreased activity of MRSA infection. After three months of antibiotic treatment, proteinuria was negative and the level of serum Cr had dropped to 0.9 mg/dl. These findings suggest that antibiotic treatment can lead to complete remission of MRSA-associated glomerulonephritis.

Chronic disseminated intravascular coagulation (DIC) is a well-known complication of aortic aneurysm. A 91-year-old Japanese woman was admitted to our hospital because of massive purpura of the lower limbs. The presence of abdominal aortic aneurysm (AAA) had been pointed out from the age of 80 years, and its diameter had gradually increased. The AAA was composed of two portions, that is, a large upper and a small lower portion, and a large mural thrombosis was observed in the lower portion. The laboratory data led to the diagnosis of DIC, and AAA was the only identifiable cause of coagulopathy. The time course of exacerbation of AAA was consistent with the progression of thrombocytopenia and purpura. Therefore, we concluded that AAA was the underlying cause of DIC. Since DIC in aortic aneurysms is associated with excessive fibrinolysis, tranexamic acid was administered as anti-fibrinolytic therapy. After that, coagulopathy was drastically improved. Our patient responded successfully to anti-fibrinolytic therapy for coagulopathy. The present case illustrates the importance of evaluation of the diameter of an aneurysm as well as intraluminal thrombosis, which may play an important role in coagulopathy including DIC. It is necessary to monitor coagulation and fibrinolysis for the follow-up of patients with AAA. <Learning objective: We present a case report of an aged Japanese woman with abdominal aortic aneurysm associated with disseminated intravascular coagulation, and anti-fibrinolytic therapy drastically ameliorated her condition. Our case illustrates the importance of evaluation of the diameter of an aneurysm as well as conducting follow-up monitoring of coagulation and fibrinolysis.>.
