Item The rate, risk factors, and outcome of fungal peritonitis in CAPD patients: Experience in Turkey(Sage Publications, 2000) Taşkapan, Hülya; Özener, Çetin; Ateş, Kenan; Akçiçek, Fehmi; Yılmaz, Muzaffer; Ataman, Rezzan; Bozfakioğlu, Semra; Camsarı, Taner; Ersoy, F. Fevzi; Karayaylalı, İbrahim; Akpolat, T.; Utaş, Cengiz; Yavuz, Mahmut; Uludağ Üniversitesi/Tıp Fakültesi/Nefroloji Anabilim Dalı.Continuous ambulatory peritoneal dialysis (CAPD) is an increasingly popular replacement therapy for patients with end-stage renal disease (ESRD). However, peritonitis continues to be a frequent complication of CAPD. Pathogenic bacteria and a small number of fungi cause the majority of cases of peritonitis. In most series, about 2% – 10% of CAPD-related peritonitis episodes have a fungal etiology. About 80% – 90% of fungal peritonitis (FP) episodes are caused by yeasts of the Candida species, less frequently by a variety of other yeasts and filamentous fungi. Fungal peritonitis is often a major cause of treatment failure in patients on CAPD and carries high risk of morbidity and mortality. The risk factors that predispose to the development of FP and regimens for FP treatment are not clear. In an attempt to identify the rate and risk factors for FP, and to examine outcome in relation to treatment strategies, we reviewed our experience with FP in this multicenter study.Item Severe vitamin D deficiency in chronic renal failure patients on peritoneal dialysis(Dustri-Verlag Dr Karl Feistle, 2006) Taşkapan, Hülya; Ersoy, F.

Method: This cross-sectional, multicenter study was carried out in 273 PD patients with a mean age of 61.7 +/- 10.9 years and mean duration of PD 3.3 +/- 2.2 years. It included 123 female and 150 male patients from 20 centers in Greece and Turkey, countries that are on the same latitude, namely, 36 - 42 degrees north. We measured 25(OH)D-3 and 1.25(OH)(2)D-3 levels and some other clinical and laboratory indices of bone mineral metabolism. Results: Of these 273 patients 92% (251 patients) had vitamin D deficiency i.e. serum 25(OH)D-3 levels less than 15 ng/ml, 119 (43.6%) had severe vitamin D deficiency i.e. serum 25(OH)D-3 levels, less than 5 ng/ml, 132 (48.4%) had moderate vitamin D deficiency i.e. serum 25(OH)D3 levels, 5 - 15 ng/ml, 12 (4.4%) vitamin D insufficiency i.e. serum 25(OH)D3 levels 15 - 30 ng/ml and only 10 (3.6%) had adequate vitamin D stores. We found no correlation between 25(OH)D-3 levels and PTH, serum albumin, bone alkaline phosphatase, P, and Ca x P. In multiple regression analyses, the independent predictors of 25(OH)D-3 were age, presence of diabetes (DM-CRF), levels of serum calcium and serum 1.25(OH)(2)D-3- Conclusion: We found a high prevalence (92%) of vitamin D deficiency in these 273 PD patients, nearly one half of whom had severe vitamin D deficiency. Vitamin D deficiency is more common in DM-CRF patients than in non-DM-CRF patients. Our findings suggest that these patients should be considered for vitamin D supplementation.
