- Peritonite esclerosante encapsulante pós-diálise peritoneal(2013) CESTARI, Alexandre Tagliari; CONTI, Marina Lourenço de; PRATS, João Antonio Gonçalves Garreta; SATO JUNIOR, Henri; ABENSUR, HugoPatients with chronic renal failure in use of peritoneal dialysis (PD) are subject to various complications of the renal replacement therapy. We report a rare complication of PD in which the peritoneum, after years of contact with hypertonic dialysate, is gradually replaced by fibrous tissue. This patient had several complications after initiation of PD including a bacterial peritonitis, tertiary hyperparathyroidism (being treated with parathyroidectomy 2) and cholelithiasis (being treated with laparoscopic cholecystectomy). After 8 years of peritoneal dialysis was transferred to hemodialysis by decreasing ultrafiltration and episodes of intestinal sub-occlusion, being diagnosed as sclerosing encapsulating peritonitis (SEP). He is currently on corticotherapy with a significant reduction of symptoms and likely stabilization of the SEP.

- Fisiologia do transporte de fluidos e solutos atraves da membrana peritoneal(2014) AGUIRRE, Anna Rita; ABENSUR, HugoIn this review, phenomena involved in fluid and solute exchange through the peritoneal membrane, both in the physiologic and in the peritoneal dialysis settings, are explained. For that purpose, mathematical models developed for the study of molecule transport through the membrane, such as the ""Pore Model"" and the ""Distributive Model"" are used. Scientific accomplishments in the field are described and areas that require additional research are also cited. Knowledge about the physiologic mechanisms involved in this renal replacement therapy modality, concerning events directly related to the peritoneal membrane itself, is synthesized in this manuscript.
- Acometimento renal na doença de Fabry(2016) ABENSUR, Hugo; REIS, Marlene Antônia dosAbstract Every cell in the human body has globotriaosylceramide accumulation (Gb3) in Fabry disease due to the mutation in gene of the enzyme α-galactosidase A. It is a disease linked to sex. The main clinical features are: cutaneous angiokeratomas; acroparestesias and early strokes; decreased sweating and heat intolerance; ocular changes; myocardial hypertrophy, arrhythmias; gastrointestinal disorders and renal involvement. Renal involvement occurs due to Gb3 accumulation in all types of renal cells. Therefore, patients may present glomerular and tubular function disorders. Podocytes are particularly affected, with pedicels effacement and development of proteinuria. The diagnosis is made by detection of reduced plasma or leukocyte α-galactosidase activity and genetic study for detecting the α-galactosidase gene mutation. Treatment with enzyme replacement contributes to delay the progression of kidney disease, especially if initiated early.
