ABSTRACT
Na+/K+-ATPase (NKA) is abundantly expressed in the basolateral membrane of epithelial cells, which is necessary for tight junction formation. The tight junction is an urothelial barrier between urine and the underlying bladder. Impairment of tight junctions allows migration of urinary solutes in patients with interstitial cystitis/painful bladder syndrome (IC/PBS). We evaluated NKA expression and activity in bladder samples from patients with IC/PBS. The study group consisted of 85 patients with IC/PBS, and the control group consisted of 20 volunteers. Bladder biopsies were taken from both groups. We determined the expression and distribution of NKA using NKA activity assays, immunoblotting, immunohistochemical staining, and immunofluorescent staining. The protein levels and activity of NKA in the study group were significantly lower than the control group (1.08 ± 0.06 vs. 2.39 ± 0.29 and 0.60 ± 0.04 vs. 1.81 ± 0.18 micromol ADP/mg protein/hour, respectively; P < 0.05). Additionally, immunofluorescent staining for detection of CK7, a marker of the bladder urothelium, predominantly colocalized with NKA in patients in the study group. Our results demonstrated the expression and activity of NKA were decreased in bladder biopsies of patients with IC/PBS. These findings suggest that NKA function is impaired in the bladders from patients with IC/PBS.

O objetivo deste estudo foi traduzir e adaptar à cultura brasileira os instrumentos The O'Leary-Sant e PUF, utilizados no diagnóstico de cistite intersticial. Foram realizadas as etapas metodológicas recomendadas pela literatura internacional para a adaptação cultural. As etapas de tradução, síntese das traduções e retrotradução foram realizadas satisfatoriamente, e a avaliação das versões sintéticas pelo comitê de especialistas resultou em algumas alterações, assegurando as equivalências entre as versões originais e traduzidas. O PUF foi pré-testado entre 40 sujeitos e The O'Leary-Sant em uma amostra de 50 indivíduos, devido à necessidade de ajustes em decorrência da baixa escolaridade da população. O processo de tradução e adaptação foi realizado com sucesso e os instrumentos, após as modificações, demonstraram ser de fácil compreensão e rápido preenchimento. Entretanto, este é um estudo que antecede o processo de validação e será premente o emprego do instrumento em novas pesquisas para que sejam avaliadas suas propriedades psicométricas.
The aim of this study was to translate and adapt the instruments known as The O'Leary-Sant and PUF to the Brazilian culture used in the diagnosis of interstitial cystitis. We followed the methodological steps recommended by the international literature for cultural adaptation. The steps of translation, synthesis of translations and back translation were performed satisfactorily and evaluation the versions of the synthesis by the panel of experts has resulted in some changes, ensuring the equivalence between the original and translated versions. The PUF was pretested among 40 subjects and The O'Leary-Sant in a sample of 50 individuals due to the need for adjustments due to the low education population. The translation and adaptation process was successful and the instruments, after some modifications, proved easy to understand and complete quickly. However, this is a study prior to the validation process and will be promoting the use of the instrument in new research to assess its measurement properties.

Síndrome da dor vesical é a nomenclatura proposta para substituir o termo antigamente conhecido como cistite intersticial. Deve ser diagnosticada com base nas queixas de dor, pressão ou desconforto pélvico crônico, relacionados à bexiga acompanhados por pelo menos outro sintoma urinário como urgência ou aumento de frequência. A prevalência estimada é de 300 por 100.000 mulheres. A etiologia e a fisiopatologia ainda não foram elucidadas, mas mecanismos neurológicos centrais, fatores genéticos, imunológicos e infecciosos parecem estar envolvidos. O diagnóstico é de exclusão e deve ser baseado nos sintomas. O teste com cloridrato de potássio intravesical não deve ser usado como ferramenta diagnóstica. A cistoscopia com hidrodistensão e biópsia auxilia na documentação e classificação da doença. O tratamento deverá ser multidisciplinar e multimodal, associando-se medicações orais com intravesicais, modificações na dieta e no estilo de vida e medidas não farmacológicas
Bladder pain syndrome is the nomenclature proposed to replace the term formerly known as interstitial cystitis. It should be diagnosed based on complaints of pain, chronic pelvic pressure or discomfort related to bladder accompanied by at least one other urinary symptom, such as urgency or increased frequency. The estimated prevalence is 300 per 100,000 women. The etiology and pathophysiology have not been elucidated, but central neurologic mechanisms, genetic, immunological and infectious factors seem to be involved. The diagnosis is by exclusion and should be based on symptoms. The test with intravesical potassium chloride should not be used as a diagnostic tool. Cystoscopy with hydrodistenstion and biopsy assist in the documentation and classification of the disease. Treatment should be multidisciplinary and multimodal, associating intravesical and oral medications, changes in diet and in lifestyle and nonpharmacological measures

La cistitis intersticial se define como un síndrome clínico caracterizado por un incremento de la frecuencia urinaria, urgencia miccional y/o dolor abdominal o perineal en ausencia de infección urinaria o enfermedad conocida del aparato urinario. Se divide de acuerdo a los hallazgos citoscópicos en ulcerativa o no. La base del diagnóstico es clínica apoyada en scores de probabilidad y pruebas invasivas. Con la comprensión de la fisiopatología se ha desarrollado un abanico de posibilidades terapéuticas. Comunicamos el caso de una paciente sintomática por cuatro años con diagnóstico de cistitis intersticial con úlcera de Hunner por cistoscopia y excelente respuesta a la amitriptilina. Es una enfermedad que produce considerable alteración de la calidad de vida, por lo que es importante que los médicos estén familiarizados con este cuadro.
Interstitial cystitis is characterized by over 6 months of chronic pain, pressure and discomfort felt in the lower pelvis or bladder. It is often relieved with voiding, along with daytime frequency and nocturia in the absence of an urinary tract infection. The disorder can be divided clinically into two groups -ulcerative and non-ulcerative- based on cystoscopic findings and response to treatment. Management follows an approach of applying the least invasive therapy that affords sufficient relief of symptoms. We report a case of a patient with interstitial cystitis. The diagnosis was performed by symptoms and lesion in the cystoscopy and excellent response to amitriptyline.

OBJECTIVE: To report our experience with cystectomy and ileal neobladder for women with interstitial cystitis (IC). MATERIALS AND METHODS: Thirty-five female patients treated during 2000-2005 with the mean age of 45.9 ± 4.4 years were included in this study. All of them had experience suprapubic pain with irritative voiding symptoms and were diagnosed as having IC based on NIDDK criteria for at least 2 years. Conservative treatments had failed to relieve their symptoms; and therefore all of them agreed to undergo a bladder removal. For cystectomy, the urethra was cut 0.5 cm below the bladder neck, proximal to the pubourethral ligament, leaving the endopelvic fascia intact. An ileal segment of 65 cm was used to create the neobladder with the Studer's technique. RESULTS: All patients presented good treatment outcome with regard to both diurnal and nocturnal urinary control without any pain. Quality of life using the SF-36 questionnaire showed significant improvement of both physical health and mental health. Spontaneous voiding with minimal residual urine was found in 33 cases (94.3 percent), and the remaining 2 cases (5.7 percent) had spontaneous voiding with residual urine and were placed on clean intermittent catheterization (CIC). Twelve out of 30 cases with sexually active ability had a mild degree of dyspareunia but without disturbance to sexual life. CONCLUSION: Bladder substitution by ileal neobladder for women who suffer from IC can be a satisfactory option after failure of conservative treatment. Resection of the urethra distal to the bladder neck can preserve continence and allow spontaneous voiding in almost all patients.

Esta revisão destaca a importância da inclusão da cistite intersticial na lista de possíveis doenças que estejam envolvidas na gênese da dor pélvica crônica, além de sua adequada investigação diagnóstica e tratamento. Foi feita uma revisão bibliográfica não sistemática sobre o tema abordado , utilizando-se a base de dados do Medline. Na paciente com dor pélvica crônica deve-se suspeitar de cistite intersticial quando, associado à dor, exixtir a queixa de urgência, frequência miccional aumentada. A investigação ser feita com cistoscopia, teste do potássio e avaliação urodinâmica. A cicstite intersticial é um distúrbio crônico do trato urinário inferior. Não há medicação curativa para essa patologia, porém um tratamento de alívio dos sintomas pode proporcionar uma melhora na qualidade de vida.
