Sclerosing encapsulating peritonitis (SEP) is a most serious complication of continuous ambulatory peritoneal dialysis (CAPD) . Although the criteria of diagnosis and guidelines for therapy of SEP have been proposed by the Japanese SEP Study Group already, SEP is refractory to treatment when the disease process is complete. It is important to detect the latent phase of SEP (pre-SEP state) in order to treat patients at an early stage. We evaluated the characteristics of ascites in four patients with massive ascites accumulation after discontinuation of CAPD. Age and the duration of CAPD of the subjects were 53.3±9.7 years and 126.5±6.8 months, respectively. However, the patients were withdrawn from CAPD because of peritonitis or ultrafiltration failure. We also followed cytokines and parameters of collagen metabolism of ascites in two patients during adrenocorticosteroid therapy and conducted a histopathological evaluation of the peritoneum of an autopsy case who had died of pneumonia. Ascites seems to be exudative because of the high concentration of protein, cytokines and parameters of collagen metabolism such as interleukin-1β, interleukin-6, transforming growth factor-β1, procollagen 3 peptide, and type IV collagen 7S, the levels of which were 21.3±9.3 pg/ml, 8, 153±7, 327 pg/ml, 6.7±3.6 ng/ml, 89.3±67.8 U/ml, and 59.0±36.2 ng/ml, respectively. The histopathological findings of the peritoneum from the autopsy case showed dense fibrous tissue permeated with inflammatory infiltration and widespread infiltration of fibrin. These findings suggested that the peritoneum was inflamed when massive ascites accumulated. The amount of ascites and concentration of cytokines and parameters of collagen metabolism of ascites diminished during adrenocorticosteroid therapy. We concluded that massive and refractory accumulation of ascites appearing after the discontinuation of CAPD should be regarded as a sign of the pre-SEP state, and prophylactic treatment should be started at this stage of disease.
