Bacillus Calmette-Guérin-induced perinuclear antineutrophil cytoplasmic antibodies associated vasculitis in bladder cancer.

Intravesical instillation of Bacillus Calmette-Guérin (BCG) immunotherapy remains the most effective adjuvant treatment for noninvasive bladder cancer. Systemic BCG-related complications are rare and usually related to infective agent or an immune-mediated reaction. We discussed a case with perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) vasculitis, developing after instillation of BCG for non-invasive bladder cancer. A 68-year-old man presented with nephritic syndrome a few months after BCG instillations which was performed for his non-muscle-invasive bladder cancer adjuvant therapy. The renal function had declined slowly after the first instillation and urinary sediment reveals the new onset of nephritic proteinuria and hematuria. High titer of p-ANCA was present. His renal biopsy was consistent with acute renal vasculitis. The patient's creatinine level regressed with immunosuppressive therapy and he was clinically followed up without hemodialysis. Here, we presented a patient that diagnosed as p-ANCA related vasculitis occurred after BCG instillation.

Leptospirosis With Acute Renal Failure and Vasculitis: A Case Report.

Leptospirosis is a zoonotic disease that occurs worldwide. Various clinical manifestations of leptospirosis can be seen. In this article, we present a case with acute renal failure, severe vasculitis and hyperbilirubinemia occurring simultaneously with leptospirosis. A 45-year-old male patient presented with fever, myalgia, jaundice and reddish skin lesions and anuria. Physical examination findings were icteric sclera, large tender hepatomegaly, and lower extremities' cutaneous necrosis due to vasculitis. Hemodialysis was started. Kidney biopsy revealed degenerative changes of proximal tubules, some of them containing bile casts. Microscopic agglutination test was positive and consistent with leptospirosis. Intravenous ampicillin and oral tetracycline were started. Methylprednisolone 60 mg per day was given for skin vasculitis. Hemodialysis therapy was discontinued. All clinical findings gradually regressed.

First molecular characterization of feline immunodeficiency virus in Turkey.

In this study, strains of feline immunodeficiency virus (FIV), designated TR-D, TR-Mo and TR-Mi, isolated from three cats in Turkey, were characterized. PCR products (859 bp) from the envelope (env) gene region were amplified and sequenced, and possible geographical differences in the env gene region of Turkish FIV strains are discussed. Phylogenetic analysis of two strains showed that FIV subtype B was present in Turkey. Phylogenetic analysis showed that one new Turkish FIV strain occupies a separate branch from known clusters (subtypes A to E) from the USA, Canada, Europe and Japan.
