ABSTRACT
La esclerosis peritoneal encapsulante es una complicación poco común, pero muy grave, de la diálisis peritoneal. Esta complicación está asociada con altas tasas de morbilidad y mortalidad. El diagnóstico clínico requiere la presencia de obstrucción intestinal o función gastrointestinal alterada con signos patológicos y radiológicos de encapsulamiento intestinal. El diagnóstico patognomónico es solo con la realización de una biopsia peritoneal. El mecanismo patogénico exacto de esta entidad sigue siendo desconocido, aunque se asocia firmemente con el tiempo de duración del paciente en el tratamiento con diálisis peritoneal. Se presenta un caso clínico de esclerosis peritoneal encapsulante y se analizan las manifestaciones clínicas, diagnóstico, tratamiento, pronóstico y prevención(AU)
Encapsulating peritoneal sclerosis is a rare but very serious complication of peritoneal dialysis. This complication is associated with high morbidity and mortality rates. Clinical diagnosis is based on the presence of intestinal obstruction or altered gastrointestinal function with pathological and radiological signs of intestinal encapsulation. The pathognomonic diagnosis is achieved only by performing peritoneal biopsy. The exact pathogenic mechanism of this entity remains unknown, although it is strongly associated with the duration of the patient with peritoneal dialysis. We report a clinical case of encapsulating peritoneal sclerosis and the clinical manifestations, diagnosis, treatment, prognosis and prevention are analyzed(AU)

Encapsulating peritoneal sclerosis (EPS) is a rare but severe complication of peritoneal dialysis. A total of 50% of the patients died within 12 months after being diagnosed. There are no obvious clinical symptoms in the early stage of EPS, which is easy to be missed. And there are few case reports of EPS in early stage. On December 22, 2018, a 70-year-old male patient undergoing peritoneal dialysis for 17 months, who was diagnosed as EPS, was admitted to the Department of Nephrology, the Third Xiangya Hospital, Central South University. The patient's peritoneal dialysis catheter was obstructed after peritonitis. The peritoneal dialysis fluid couldn't be drain in and out of the abdominal cavity. Therefore, the laparoscopy was performed to repair the catheter. The operation in progress showed that the peritoneum was slightly thickened and the ileocecal intestinal tube was closely adhered to the parietal peritoneum where the catheter was wrapped, indicating the early stage of EPS. Peritoneal relaxation was performed. The patient's catheter was normal after adhesiolysis. He underwent hemodialysis, nutritional supporting as well as peritoneal dialysis transition, etc. The peritonitis was controlled after 10 days and the peritoneal dialysis was resumed. After discharge from hospital, the patient took moxifloxacin for 2 more weeks. We followed up the patient for 6 months. The automated peritoneal dialysis is maintained, and everything remains normal. Clinicians need to improve understanding of EPS. Early diagnosis and laparoscopic adhesiolysis is helpful to continue peritoneal dialysis treatment.

Background: Encapsulating peritoneal sclerosis (EPS) is a complication of peritoneal dialysis (PD) with a low prevalence but high mortality. It is characterized by peritoneal inflammation and fibrosis with subsequent development of intestinal encapsulation. It is associated with a long lapse on PD, frequent episodes of peritonitis, high glucose solution use, and high peritoneal transport status. Aim: To report the clinical features of patients on PD, who developed EPS. Material and Methods: Review of medical records of 12 patients aged 43 ± 10 years (eight women) who developed EPS. Results: The mean time spent on PD was 98 months. The main clinical manifestations were abdominal pain in 82% and ultrafiltration failure in 63%. In 92%, there was a history of peritonitis and 75% had high peritoneal transport at the time of diagnosis. The main findings in computed tomography were peritoneal calcification and thickening. There was a biopsy compatible with the diagnosis in 10 cases. Treatment consisted in withdrawal from PD, removal of PD catheter and the use of corticoids and tamoxifen. After withdrawal from PD 50% of patients became asymptomatic. The rest had intermittent abdominal pain and altered bowel movements. Two patients died (17%). Conclusions: EPS is a serious complication of PD, which should be suspected in any patient with compatible clinical symptoms, long time on PD, multiple episodes of peritonitis and high peritoneal transport profile.

PURPOSE: To investigate the influence of using simvastatin on the peritoneal fibrosis induced in rats using peritoneal dialysis solution with glucoses 4.25%. METHODS: Prospective controlled study in 20 non-uremic Wistar rats. The animals received a peritoneal infusion of 10 ml/100 g of peritoneal dialysis solution glucose 4.25% on a daily basis. The animals were divided in two groups: experimental and control. The experimental group received simvastatin 4 mg/kg/d, by a gastric tube. The control group did not receive any drug. The follow-up was 21 and 49 days. At the end, one surgical procedure was performed to get histological samples of visceral and parietal peritoneum. The samples were analyzed using Hematoxylin Eosin and Sirius Red, to evaluate the severity of the fibrosis. RESULTS: The analysis showed that the intensity of the fibrosis, the peritoneal thickness and the cell number in experimental and control groups were not statistically significant different in experimental and control groups. CONCLUSION: The simvastatin do not decrease the intensity of fibrosis on the peritoneal membrane that happens on rats on peritoneal dialysis.
OBJETIVO: Investigar a influência do uso da sinvastatina na fibrose peritoneal induzida em ratos pelo uso de solução de diálise peritoneal rica em glicose. MÉTODOS: Estudo prospectivo controlado, em ratos Wistar não urêmicos. Foram estudados 20 animais. Os animais foram submetidos diariamente à punção abdominal, sendo infundida solução de diálise peritoneal com glicose a 4,25% na dose de 10 ml/100 g de peso. Os animais foram divididos em dois grupos: experimental e controle. O grupo experimental recebeu sinvastatina na dose de 4 mg/kg/dia por gavagem. O grupo controle não recebeu nenhuma droga. Foram acompanhados por 21 e 49 dias. Ao final do período foram submetidos à procedimento cirúrgico para retirada de peritônio parietal e visceral. As amostras obtidas foram analisadas histologicamente, usando-se coloração Hematoxilina - Eosina e Sirius Red, para avaliação do grau de fibrose. RESULTADOS: A análise mostrou que a intensidade da fibrose, a espessura do peritônio e o número de células não atingiram diferença estatisticamente significante entre os grupos experimental e controle. CONCLUSÃO: A sinvastatina não foi capaz de alterar a intensidade da fibrose peritoneal induzida pelo uso de solução de diálise em ratos.
