Transaldolase (TALDO) deficiency is a recently described inborn error of metabolism of the pentose phosphate pathway that so far has been diagnosed in only eight patients. In this article, we report the clinical course and biochemical findings of two newly identified patients with TALDO deficiency-two sons of consanguineous parents from Polish origin,(More)
Hepatocellular carcinoma (HCC) is rare in young children. We attempted to see if immunohistochemical and mutational-analysis studies could demonstrate that deficiency of the canalicular bile acid transporter bile salt export pump (BSEP) and mutation in ABCB11, encoding BSEP, underlay progressive familial intrahepatic cholestasis (PFIC)--or "neonatal(More)
BACKGROUND & AIMS Patients with severe bile salt export pump (BSEP) deficiency present as infants with progressive cholestatic liver disease. We characterized mutations of ABCB11 (encoding BSEP) in such patients and correlated genotypes with residual protein detection and risk of malignancy. METHODS Patients with intrahepatic cholestasis suggestive of(More)
UNLABELLED Available data on prevalence of HCV genotypes in Poland are insufficient. The aim of the study was the analysis of distribution of HCV genotypes in Poland over the period of recent 10 years regarding the age of patients and the regions of the country. MATERIAL AND METHODS Analysis of HCV genotypes in Poland was carried out between 2003 and(More)
Progressive intrahepatic familial cholestasis (PFIC), previously called Byler's disease, is a syndrome in which children develop severe cholestasis progressing to biliary cirrhosis and chronic liver failure, usually during the first decade of life. Clinical features include jaundice, hepatomegaly, splenomegaly, growth retardation and severe pruritus.(More)
OBJECTIVES Children with progressive familial intrahepatic cholestasis (PFIC) rarely benefit from medical treatment and most patients require surgical intervention. Partial external biliary diversion (PEBD) is presently the treatment of choice but for those who cannot benefit from PEBD, an alternative surgical procedure--ileal exclusion (IE)--was(More)
BACKGROUND Epstein-Barr virus (EBV) is associated with most cases of the post-transplant lymphoproliferative disorders developed during the first year after transplantation. The high EBV DNA load constitutes a major risk for the development of EBV-related lymphoproliferations. However, among transplant recipients there are patients with a chronically high(More)
OBJECTIVES Study was performed to evaluate prospectively long-term renal function in pediatric liver transplant recipients. METHODS In 50 children aged 1-18 years, renal function tests (sCr, GFR, ERPF, Cr clearance, renal Doppler ultrasound, ABPM) have been performed before and several times during 36 months follow-up after liver transplantation.

PURPOSE Candidiasis is an infectious complication in organ transplant recipients resulting from the patients' immunodeficiency and virulence of fungi pathogens. The purpose of this study was to evaluate the frequency of Candida spp. and identify their presence in the oral lesions of graft recipients. METHODS This study included 185 patients, 1.5 to 25.2(More)
