C-reactive protein as an indicator of inflammatory responses to experimentally induced cystitis in dogs

The aim of this study was to demonstrate and assess C-reactive protein (CRP) changes in dogs with induced bacterial cystitis with or without antibiotics. We also evaluated availability of CRP levels to serve as an indicator for monitoring or diagnosing bacterial cystitis. Serial CRP concentrations in dogs with induced bacterial cystitis were higher than those of controls (p < 0.001). CRP concentrations peaked on day 7 and gradually decreased thereafter. In the treatment group, CRP concentrations decreased after medication compared to the untreated group (p = 0.032). CRP levels had a linear correlation with urine white blood cell counts among all groups (r = 0.837, p < 0.001, n = 140). Compared to the negative urine culture group, dogs with positive urine culture results had higher CRP concentrations (median 43.8 mg/L vs. 5.9 mg/L; p < 0.001). Area under the receiver operating characteristic curve was 0.955; when cut-off value was 12.2 mg/L, CRP measurements were found to have a sensitivity of 92.3% and specificity of 86.4%. This result indicates that rapid increases of CRP occurred after inducing bacterial cystitis and CRP may be a useful indicator for monitoring or diagnosing canine bacterial cystitis together with sediment urinalysis and urine bacterial culture.

Cistite glandular evoluindo com uropatia obstrutiva / Cystitis glandularis evolving with obstructive uropathy

Introdução: Cistite glandular é um processo proliferativo benigno e infrequente da mucosa vesical, caracterizado por proliferação do epitélio e, em alguns casos, formação de glândulas intestinais. Alterações metaplásticas na cistite glandular são bem documentadas na literatura, embora sua etiologia não seja totalmente esclarecida. Relato do caso: Relatamos um caso de cistite glandular em um paciente de 55 anos, apresentando sintomas miccionais irritativos e obstrutivos persistentes sem resposta à terapia com alfabloqueadores. Ultrassonografia evidenciou lesão vegetante no trígono vesical e o paciente foi submetido à ressecção endoscópica por duas vezes e evoluiu com ureterohidronefrose bilateral. Dado o extenso acometimento vesical e a persistência dos sintomas, o paciente foi submetido a cistoprostatectomia e neobexiga ileal com boa evolução pós-operatória. Discussão: Há duas formas de cistite glandular: típica e intestinal. A forma típica é a mais comum e a intestinal é marcada pela produção de mucina, mais frequentemente associada ao adenocarcinoma de bexiga. A maioria dos casos de cistite glandular é assintomática, sendo que os pacientes sitomáticos normalmente apresentam hematúria, sintomas urinários irritativos e típicos de cistite crônica. Há controvérsias sobre o tratamento precoce agressivo, sendo que vários estudos propõem a ressecção transuretral e o acompanhamento com biópsias.

Introduction: glandular cystitis is a benign proliferative process and infrequent mucosal bladder, characterized by proliferation of the epithelium and in some cases, formation of intestinal glands. Metaplásticas changes in glandular cystitis are well documented in the literature, although its etiology is not fully understood. Case report: A case of glandular cystitis in one patient of 55 years, with irritative and obstructive urinary symptoms persisted without response to therapy with alpha blockers. Ultrasonography revealed a vegetative lesion in the trigonal and the patient underwent endoscopic resection and twice progressed to bilateral ureterohidronefrose. Given the extensive bladder involvement and persistence of symptoms, the patient underwent ileal neobladder cistoprostatectomia and with good postoperative evolution. Discussion: There are two types of glandular cystitis: typical and intestinal tract. The typical form is the most common and is characterized by intestinal mucin production, most often associated with adenocarcinoma of the bladder. Most cases of glandular cystitis is asymptomatic, and patients usually present sitomáticos hematuria, urinary symptoms and typical of chronic cystitis. There is controversy over early aggressive treatment, and several studies suggest transurethral resection and follow-up biopsies.
