摘要
Background: Cyclophosphamide therapy is associated with several urological complications including urinary bladder malignancy. Data on urologic complications of chronic cyclophosphamide therapy for dermatologic conditions is not available. Objectives: To study the urocytological profile of pemphigus patients on long-term cyclophosphamide therapy. Materials and Methods: In a cross-sectional study, consecutive patients who had received cyclophosphamide therapy for pemphigus for more than 12 months were included. All patients were subjected to urinalysis including microscopy, culture, and urine cytology. Immunocytochemical staining for cytokeratin 20 (CK-20) on urine sediments and ELISA (enzyme-linked immunosorbent assay) for nuclear membrane protein-22 (NMP-22) were performed in all cases. In patients with urinary symptoms, microscopic hematuria, or those detected with abnormal urine sediment cytology, NMP-22, and CK-20 positivity, cystoscopy, and other relevant investigations were also done. Results: A total of 44 patients (43 of pemphigus vulgaris and one of pemphigus foliaceus) were recruited. Mean duration of cyclophosphamide intake was 2.9 +/- 1.7 years (range 1-8 years) with a mean cumulative dose of 53 +/- 28.4 g (range 6.5-141 g). Twenty-one cases (47.7%) each were asymptomatic and symptomatic with episodic urinary symptoms [of which two had urinary tract infection (UTI)] and two patients had gross hematuria. Urine cytology revealed mild urothelial nucleomegaly with hyperchromasia in four patients. However, CK-20 and NMP-22 were negative in all samples. Cystoscopy was performed in 21 cases and did not reveal any sign of bladder malignancy. Limitations: A relatively small sample size and lack of long-term follow-up were limitations. Conclusions: In our study, no serious urologic complications were found in pemphigus cases on chronic cyclophosphamide therapy.
