Abstract
Background/Aim Prolonged jaundice is one of the most common problems during neonatal period. The aim of this study was to evaluate the efficiency of ursodeoxycholic acid (UDCA) treatment in newborn infants with prolonged unconjugated hyperbilirubinemia. Materials and Methods The present study included 27 patients who were fed by breast milk and followed up in the outpatient clinic due to prolonged jaundice without any underlying etiological factor; 10 mg/kg/day UDCA was administrated in two doses for 7 days. Furthermore, 20 newborns diagnosed with prolonged jaundice with same characteristics were enrolled as the control group. The control group was also given a placebo; demographic characteristics, liver functions tests before and after the treatment, bilirubin decrease rates, and hemogram parameters of groups were compared. Results Total bilirubin levels in the study and control groups before the treatment were 16.02 ± 1.41 mg/dL and 15.93 ± 1.66 mg/dL, respectively (P = 0.84). Total bilirubin levels in the study and control groups at day 7 after UDCA treatment were detected 8.18 ± 2.31 mg/dL and 13.92 ± 2.66 mg/dL, respectively (P < 0.001), and at day 14 after the treatment were 5.45 ± 2.59 mg/dL and 11.91 ± 2.83 mg/dL, respectively (P < 0.001). Furthermore, serum aspartate aminotransferase (AST) was detected <21 U/L in the ROC analysis after UDCA treatment (P = 0.04). Conclusion The study outcomes indicated that an efficient reduction in total bilirubin levels may be achieved, and outpatient clinic follow-up period may be reduced in patients whom UDCA was administrated. Moreover, it may be speculated that AST can be used to evaluate the efficacy after treatment. However, studies with larger sample sizes are needed for the routine use of UDCA in the treatment of prolonged jaundice.

Abstract
Background Neonatal jaundice is a transitional phenomenon affecting three out of five full-term newborns globally. Ursodeoxycholic acid could be beneficial in neonatal jaundice needing phototherapy. Methods We searched PubMed, EBSCO, ProQuest, and Cochrane Library up to August 21st, 2021, for articles to be reviewed. Meta-analysis using random-effects model was performed. Results Eight studies involving 1116 neonates were chosen in this review; however, only five studies were included for meta-analysis. Phototherapy duration was significantly lower in the interventional group with high heterogeneities. Subgroup analysis of the phototherapy duration based on the risk of bias resulted in a shorter duration (mean difference (MD) = –17.82; 95% CI = –20.17 to –15.47; p = < 0.001) with low heterogeneity in the treatment group. Secondary outcome focusing on mean total serum bilirubin showed a lower mean total serum bilirubin in 48 h post-treatment (MD = –0.43; 95% CI = –0.64 to –0.22; p = < 0.0001) with low heterogeneities in Asian countries.” Conclusions Ursodeoxycholic acid might be considered as a novel adjuvant therapy in neonatal indirect hyperbilirubinemia to shorten the phototherapy duration and lower the mean total serum bilirubin.

Abstract
WHAT IS KNOWN AND OBJECTIVES Ademetionine 1,4-Butanedisulfonate (SAMe) enteric-coated tablets are widely used for treatment of pre-cirrhotic and cirrhotic intrahepatic cholestasis, as well as intrahepatic cholestasis of pregnancy (ICP), but incomplete clinical data and interference from endogenous substances pose numerous challenges for clinical trial of ademetionine. The objective of this study was to evaluate the pharmacokinetic profile of SAMe enteric-coated tablets and to assess its food impact and safety in healthy Chinese subjects. METHODS A randomized, open-label, single-dose study was carried out to determine the pharmacokinetics of SAMe enteric-coated tablets administered in both fasted and postprandial conditions. Baseline collection and data adjustment were required to reduce the effect of endogenous substances. Relevant pharmacokinetic data from subjects administered the reference formulation will be disclosed and utilized in this thesis. RESULTS Twenty-four subjects with a body mass index (BMI) of 19-24 kg/m2 were enrolled in the study and all completed the trial. The impact of food on the drug was noticeable, with faster absorption in the fasting group (Tmax , 4.50 ± 1.07 and 7.50 ± 1.58 for the fasting and postprandial groups, respectively) but higher exposure in the postprandial group (AUC0-inf , 4021.02 ± 3377.13 and 5087.28 ± 3539.26 for the fasting and postprandial groups, respectively). No serious adverse effects were observed in the fasted and postprandial conditions. WHAT IS NEW AND CONCLUSIONS The pharmacokinetic profile of SAMe enteric-coated tablets in healthy Chinese subjects was partially complemented in this study. SAMe enteric-coated tablets showed promising safety in fasted and postprandial conditions. However, the impact of food on the drug was significant and might access to the absorption site and affect biochemical reactions.

Abstract
Chronic liver disease (CLD) is one of the leading causes of disability-adjusted life years in many countries. A recent understanding of nuclear bile acid receptor pathways has increased focus on the impact of crosstalk between the gut, bile acids, and liver on liver pathology. While conventionally used in cholestatic disorders and to dissolve gallstones, the discovery of bile acids' influence on the gut microbiome and human metabolism offers a unique potential for their utility in early and advanced liver diseases because of diverse etiologies. Based on these findings, preclinical studies using bile acid-based molecules have shown encouraging results at addressing liver inflammation and fibrosis. Emerging data also suggest that bile acid profiles change distinctively across various causes of liver disease. We summarize the current knowledge and evidence related to bile acids in health and disease and discuss culminated and ongoing therapeutic trials of bile acid derivatives in CLD. In the near future, further evidence in this area might help clinicians better detect and manage liver diseases.

Abstract
Kasai procedure (KP) and liver transplantation (LT) represent the only therapeutic options for patients with biliary atresia (BA), the most common indication for LT in the pediatric population. However, KP represents by no means a radical option but rather a bridging one, as nearly all patients will finally require a liver graft. More and more experts in the field of transplant surgery propose that maybe it is time for a paradigm change in BA treatment and abandon KP as transplantation seems inevitable. Inadequacy of organs yet makes this option currently not feasible, so it seems useful to find ways to maximize the efficacy of KP. In previous decades, multiple studies tried to identify these factors which opt for better results, but in general, outcomes of KP have not improved to the level that was anticipated. This review provides the framework of conditions which favor native liver survival after KP and the ones which optimize a positive LT outcome. Strategies of transition of care at the right time are also presented, as transplantation plays a key role in the surgical treatment of BA. Future studies and further organization in the transplant field will allow for greater organ availability and better outcomes to be achieved for BA patients.

Abstract
Chronic pruritus associated with systemic diseases in the pediatric population has been infrequently addressed in the literature. This review focuses on chronic pruritus presenting without cutaneous manifestations. Common systemic etiologies include diseases with hepatic, renal, and hematologic origins. This encompasses several congenital liver disorders, end-stage renal disease (ESRD), and lymphoproliferative disorders such as Hodgkin's lymphoma. In this paper, an expert panel describes the clinical characteristics, pathophysiology, and therapeutic treatment ladders for chronic pruritus associated with the aforementioned systemic etiologies. Novel therapies are also reviewed. Our aim is to shed light on this unexplored area of pediatric dermatology and instigate further research.

Abstract
AIM This study aimed to investigate the effect of adding ursodeoxycholic acid (UDCA) to phototherapy in neonates with glucose-6-phosphate dehydrogenase (G6PD) deficiency and hyperbilirubinaemia. G6PD deficiency is a common cause of severe hyperbilirubinaemia in neonates. METHODS This study was a triple blind, clinical trial study of 40 neonates with G6PD deficiency and hyperbilirubinaemia who admitted for phototherapy in hospitals affiliated to the University of Medical Sciences. The treatment group (n = 20) received UDCA 10 mg/kg (2 cc/kg) daily divided into 2 doses every 12 h. The control group (n = 20) received the same volume of placebo syrup. The drug and placebo treatments were continued until the bilirubin level dropped below 171 μmol/L. Both the control and treatment group received continuous phototherapy. Independent sample t-test, survival analysis and logrank test were used to statistically analyse the results. RESULTS The mean total bilirubin level was 231.9 ± 18.8 μmol/L and 184.3 ± 18.6 μmol/L in the control and intervention group respectively, 24 h after drug administration and 209.7 ± 19.3 μmol/L and 157.4 ± 16.4 μmol/L, respectively, 48 h after intervention (P < 0.05). The median length of hospitalisation in the treatment group was approximately 1 day lower than the control group (logrank test P value: <0.001). CONCLUSION The study showed that the addition of UDCA to phototherapy accelerates the reduction of total bilirubin level in neonates with G6PD deficiency and can reduce the duration of hospitalisation.

Abstract
OBJECTIVES Indirect hyperbilirubinemia during neonatal period is a common problem, and most preterm and more than half of the term neonates find this problem. Ursodeoxycholic acid (UDCA) protects the liver against oxidative stresses and prevents cellular apoptosis. In addition, it causes stimulation of bile flow, is well tolerated by the patient, and has limited side effects. Thus, the aim of this study was to investigate the effect of UDCA in treating neonates with unconjugated hyperbilirubinemia undergoing phototherapy. METHODS In this randomized clinical trial, 220 neonates with unconjugated hyperbilirubinemia who referred to Amir-Kabir Hospital, Arak, Iran in 2017-2018, were randomly assigned to phototherapy group (Control group) and phototherapy plus UDCA group (Intervention group) as 10 mg/kg/day. The level of total bilirubin was measured at the baseline, and after 12, and 24 h using spectrophotometric, and the duration of receiving phototherapy was also measured in both groups. RESULTS The mean age of included neonates in the control and intervention group was 5.3 and 4.9 days, respectively. The results revealed that after 12 h of treatment, the total bilirubin level in the control group had diminished by 2.70 mg/dL on average while, in the intervention group, the reduction was 3.7 md/dL (p = .001) and after 24 h of treatment, the total bilirubin level in the control group had diminished by 5.22 mg/dL on average and in the intervention group, the reduction was 6.54 md/dL (p = .001). It was also observed that there is no significant difference between groups in terms of the mean of the duration required for phototherapy (p = .63). CONCLUSIONS UDCA combined with phototherapy enhances TSB decrease, but this effect is not relevant from a clinical point of view because it does not decrease phototherapy and hospital stay duration. Thus, this study does not support the UDCA use in the clinical practice. TRIAL REGISTRATION IRCT, IRCT2017071515511N2.

Abstract
Biliary atresia is a progressive inflammatory sclerosing disease of the bile ducts in the neonatal liver. Without surgical intervention these patients are destined to succumb to the disease. The development of the hepatoportoenterostomy in 1959 and liver transplantation in 1963 ushered a new era of success treating these patients. While many surgical modifications and adjuncts to treatment have been attempted over the last 50 years, the mainstay of treatment to give the child the best chance at prolonged survival with the native liver is a properly performed operation, in a timely fashion, with minimal post-operative complications. This review presents the authors current practice guideline to achieve these goals.

Abstract
Dubin-Johnson syndrome (DJS) is an autosomal recessive disorder resulting from biallelic mutations of ABCC2 gene, with long-term or intermittent conjugated hyperbilirubinemia being the main clinical manifestation. This paper aims to report the clinical features and ABCC2 genotypes of an infant with DJS. A 9.5-month-old male infant was referred to the hospital due to abnormal liver function discovered over 9 months. The major clinical presentation was prolonged jaundice since neonatal period. A series of biochemistry analysis revealed markedly elevated total bilirubin, conjugated bilirubin and total bile acids. The patient had been managed in different hospitals, but the therapeutic effects were unsatisfactory due to undetermined etiology. Physical examination revealed jaundiced skin and sclera, and a palpable liver 3 cm below the right subcostal margin with medium texture. The spleen was not enlarged. Genetic analysis revealed a splice-site variant c.3988-2A>T and a nonsense variant c.3825C>G (p.Y1275X) in the ABCC2 gene of the infant, which were inherited from his mother and father respectively. The former had not been previously reported. Then ursodeoxycholic acid and phenobarbital were given orally. Half a month later, as a result, his jaundice disappeared and the biochemistry indices improved. However, the long-term outcome needs to be observed. Literature review revealed that neonates/infants with DJS presented with cholestatic jaundice soon after birth as the major clinical feature, and the ABCC2 variants exhibited marked heterogeneity.

Abstract
Jaundice with pruritus is a manifestation of cholestasis. The defective biliary drainage causes accumulation of substances that are usually excreted in bile, which in turn causes pruritus. The exact nature of the pruritogen is under evaluation. However, lysophosphatidic acid is the current favourite. The causes of cholestasis can be broadly classified as intra or extrahepatic, with intrahepatic disorders being more often associated with pruritus. Cholestatic phase of acute viral hepatitis, progressive familial intrahepatic cholestasis, syndromic and non-syndromic paucity of intralobular bile ductules, drug induced cholestasis and sclerosing cholangitis (SC) are the common causes in children. An algorithmic approach facilitates early etiological diagnosis by careful clinical evaluation combined with investigations including gamma glutamyl transpeptidase, radiological imaging (ultrasonography, magnetic resonance cholangiopancreatography), liver biopsy and genetic analysis. Management is largely supportive and includes nutritional rehabilitation with supplement of fat soluble vitamins and calcium, stepwise therapy of pruritus with drugs (ursodeoxycholic acid, rifampicin, bile acid sequestrants and/or opioid antagonists) and biliary diversion surgery. Complications of advanced liver disease and portal hypertension need to be addressed. Liver transplantation is required in children with refractory pruritus affecting the quality of life or those with end stage liver disease. Relief of biliary obstruction by endoscopy or surgery and treatment of diseases associated with SC like histiocytosis may be rewarding. Long-term follow-up for development of complications of liver disease and hepatocellular/ cholangiocarcinoma is essential. Thus, an early diagnosis and stepwise treatment with an understanding of the pathogenesis of pruritus in cholestatic disorders may decrease morbidity and mortality.

Abstract
BACKGROUND Hyperbilirubinemia is a common neonatal problem. The present study aimed to investigate the effect of ursodeoxycholic acid in reducing indirect hyperbilirubinemia of infants under phototherapy. METHODS This double-blind randomized clinical trial was conducted on neonates with jaundice, who had received phototherapy in the hospitals affiliated with the Shiraz University of Medical Sciences in 2013. A total of 80 neonates were enrolled in the study and were randomly divided into 2 groups. The intervention group (n = 0) with indirect hyperbilirubinemia received 10 mg · kg(-1) · day(-1) divided every 12 hours Ursobil (capsule 300 mg) in addition to phototherapy, whereas the control group (n = 0) received only phototherapy. Total bilirubin levels were measured every 12 hours until reaching <10 mg/dL, and then phototherapy was disrupted. The duration of phototherapy was measured. The 2 groups were compared regarding total bilirubin levels at different time points and duration of phototherapy using the generalized estimating equation (GEE) test. RESULTS The mean of total bilirubin in the intervention group was 12 ± 1.6, 10 ± 1.1, and 9.8 ± 0.2 mg/dL 12, 24, and 48 hours after the beginning of phototherapy, respectively. On the contrary, these measures were 14.4 ± 1.3, 12.5 ± 1.4, and 10.1 ± 1.1 mg/dL in the control group, respectively, (P < 0.05). The mean time required for phototherapy to decrease the bilirubin level to < 10 mg/dL was 15.5 ± 6 and 44.6 ± 13.3 hours in the case and the control group, respectively, (P = 0.001). CONCLUSIONS Ursodeoxycholic acid had additive effect with phototherapy in neonates with indirect hyperbilirubinemia. This drug also reduced the time period needed for phototherapy and, consequently, decreased the hospitalization period.

[PMID: 25305380 DOI: 10.1016/j.ijpharm.2014.10.011] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2014] [Revised: 10/02/2014] [Accepted: 10/04/2014] [Indexed: 12/26/2022]
Abstract
This paper describes a rational method of characterizing the biopharmaceutical stability of two oral suspensions of ursodeoxycholic acid (UDCA) used in pediatrics. Because there is no commercial presentation of UDCA that can administer appropriate doses for infants and children, an active pharmaceutical ingredient (API) formulation is required. Due to its very low solubility and low dose in the formula (1.5%), two different suspensions with minimal use of excipients were studied, avoiding the use of complex additives and those not recommended by the European Medicines Agency (EMA). Adherence to Standard Operating Procedure (SOP) allows the preparation of formulations with appropriately sized and stable particles, and suitable rheological behavior in withdrawing the dose after stirring. Dose uniformity, expressed as mass and content variability, was determined using the criteria of the European and the United States Pharmacopoeia. Additionally, dose content variation of every mass determined was studied. A rational method was developed for determining the dose uniformity of UDCA in suspensions, whether freshly prepared or after storage under different conditions for 30 and 60 days. This method permits detection of differences between doses taken at different heights in the vessel at various times and storage conditions. UDCA was stable under all conditions studied, requiring the presence of glycerol in the formulation to obtain the declared API value after stirring. Storage of UDCA suspensions in a refrigerator increased variability between doses.

Abstract
OBJECTIVES To verify the effect of ursodeoxycholic acid (UDCA) on the duration of neonatal parenteral nutrition-associated liver disease. METHODS Retrospective cohort study of neonates in intensive care between 2004 and 2007 presenting with parenteral nutrition-associated liver disease. RESULTS Of 118 eligible infants, 64 received UDCA. Cholestasis lasted longer in the UDCA group (79 vs. 50 days, p=0.001). However, treatment was delayed for a median of 24 days after cholestasis onset. Multivariate Cox regression analysis showed no association between UDCA and cholestasis duration. The rate of decline of conjugated bilirubin was greater in treated patients (median 0.084 mg/dL/day vs. 0.60 mg/dL/day; p=0.009) and weight gain was greater (22.8 vs. 17.7 g/kg/day, p=0.010). CONCLUSIONS UDCA therapy was not associated with the duration of parenteral nutrition-associated liver disease. A delay in treatment initiation might explain this result. UDCA therapy was associated with a faster decline of conjugated bilirubin and greater weight gain.

Abstract
Several major forces converged to catalyze the formal emergence of a body of knowledge and an organized focus on disorders of the liver in early life. Attendant to the development of a focused clinical subspecialty the pace of patient- and laboratory-based research in the field quickened in parallel to decipher the consequences of genetic or metabolic aberrations on immature liver structure and function. The key research observations that catalyzed the emergence and subsequent rapid growth of Pediatric Hepatology include: (1) an understanding of the dynamic events occurring during hepatobiliary development and the importance of these physiologic variables that occur during liver maturation; (2) the recognition of the unique nature of inherited and acquired liver diseases that affect infants and children-such as biliary atresia and Reye's syndrome; and (3) redefinition of the once obscure inherited intrahepatic cholestatic diseases of the liver, which, in turn, provided insight into normal and abnormal hepatobiliary physiology. The clinical advances were highlighted by the development of specific approaches to the diagnosis and management of liver disease in infants and children, including both liver transplantation and nontransplant treatment options. These seminal events led to the expansion of the workforce, creating a critical mass consisting of individuals with focused, specialized skills and techniques. In-depth expertise allowed more accurate diagnosis and highly effective treatment strategies for advanced hepatobiliary disease in children. The demand for pediatric clinicians with experience in advanced hepatology allowed sub-sub-specialization to flourish. Continued maturation of the field led to definition of hepatology-focused curricular elements and educational content for Pediatric Gastroenterology training programs, and subsequently the development of program requirements for those who wished to acquire additional training in Pediatric Hepatology. A significant rite of passage was marked by the election of pediatric hepatologists to leadership positions in the American Association for the Study of Liver Diseases (AASLD). Further validation of the field occurred with approval of the petition for establishing a Certificate of Added Qualification in Transplant Hepatology by the American Board of Pediatrics. Here I relate my perspective on the history of the advances in our field and the contributions of many of the clinicians and scientists whose efforts led to the development of focused clinical, research, and training programs that improved the care of children with diseases of the liver.

Abstract
OBJECTIVES The aims of the study were to perform a retrospective observational review of the present management and outcome of cholestatic pruritus in children with Alagille syndrome (AGS) at King's College Hospital and to use results to inform appropriate guidelines. METHODS A retrospective review of 62 patients diagnosed as having AGS from January 1995 to November 2010 treated at King's College Hospital was performed. The departmental database of the Paediatric Liver Centre was searched to identify all patients and the clinical records were then analysed. RESULTS Fifty-one (82.3%) patients experienced pruritus and 50 (80.6%) received antipruritic medication. Ursodeoxycholic acid was the most prescribed drug (n = 40). Other drugs prescribed were rifampicin (n = 39), cholestyramine (n = 18), naltrexone (n = 14), alimemazine (n = 13), nonsedating antihistamine agents (n = 7), ondansetron (n = 5), and phenobarbitone (n = 1). Albumin dialysis using the molecular adsorbent recirculation system was used in 1 patient. Sixteen patients (25.8%) were listed for liver transplantation, and 11 had undergone transplantation by November 2010. Patient survival was high at 95.2%. Pruritus resolved permanently in 39.2% (n = 20) of patients. Fifty-five percent (n = 11) of such patients had undergone liver transplantation. Pruritus was controlled by medication in 41.2% (n = 21). Itching remained a significant problem, affecting quality of life in 19.6% of patients (n = 10). CONCLUSIONS The management of cholestatic pruritus in AGS is difficult and often suboptimal. Pruritus may remain intractable even with combination medical treatment, and at this stage, surgery or liver transplantation is indicated. At our centre, pruritus was successfully treated in 80.4% of patients with medical and surgical management.

Abstract
Neonatal conjugated jaundice is a common presentation of hereditary liver diseases, which, although rare, are important to recognize early. Developments in molecular genetic techniques have enabled the identification of causative genes, which has improved diagnostic accuracy for patients and has led to a greater understanding of the molecular pathways involved in liver biology and pathogenesis of liver diseases. This review provides an update of the current understanding of clinical and molecular features of the inherited liver diseases that cause neonatal conjugated jaundice.

Abstract
Parenteral nutrition-associated liver disease (PNALD) is a complex disease that is diagnosed by clinical presentation, biochemical markers of liver injury, concurrent use of parenteral nutrition (PN), and negative workup for other causes of liver disease. Since the first case of PNALD was reported more than 30 years ago, clinicians have had few effective treatments for PNALD, and when disease progressed to liver cirrhosis, it was historically associated with poor outcomes. Within the past 5 years, there has been much excitement about new treatments for PNALD, including use of both parenteral and enteral ω-3 polyunsaturated long-chain fatty acids (ω-3 PUFA) as well as restricting dosing of ω-6 PUFA. Scientists are also interested in uncovering the mechanisms associated with liver injury seen in PNALD. This article reviews the recent literature relating to the pathophysiology and treatment of PNALD.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic condition affecting the extrahepatic and intrahepatic biliary tree. The incidence is seemingly increasing in children as a result of increased use of cholangiographic screening techniques in children with inflammatory bowel disease. The clinical presentation of PSC in childhood is variable and frequently without obvious cholestatic features, and cholangiography is essential for the diagnosis of this disorder. Histologic findings may help to exclude autoimmune sclerosing cholangitis. The underlying pathogenesis remains poorly understood and, as a result, therapeutic agents that halt disease progression and improve prognosis are lacking. PSC treatment is mainly supportive and directed at controlling cholestatic symptoms and preventing complications. Ursodeoxycholic acid is helpful in inducing biochemical improvement; long-term pediatric studies to determine a benefit of this agent in young patients are lacking, although results from adult studies have not been promising. Some agents such as antibiotics are under investigation with some promising results. Liver transplantation is required for children who progress to end-stage liver disease. Prospective multicenter trials in children with PSC are needed.

Abstract
Alagille syndrome is a highly variable, autosomal dominant disorder that affects the liver, heart, eyes, face, skeleton, kidneys, and vascular system. Much has been learned about the genetics of this disorder, which is caused primarily by mutations in the Notch signaling pathway ligand JAGGED1; however, the medical management of this condition is complex and continues to generate controversy. The significant variability of organ involvement requires the managing physician to have an understanding of the breadth and interplay of the variable manifestations. Furthermore, the liver disease in particular requires an appreciation of the natural history and evolution of the profound cholestasis.

Abstract
BACKGROUND/AIM Cholestatic acute viral hepatitis may have prolonged course. Pruritus is often a prominent feature and difficult to control. Sometimes it may be accompanied by severe cough. There are no reports of endoscopic nasobiliary drainage in these patients. METHODS We prospectively evaluated the role of nasobiliary drainage in six patients with cholestatic acute viral hepatitis with intractable pruritus and accompanying severe cough in one patient in an uncontrolled study. RESULTS There were five male and one female patient with cholestatic acute viral hepatitis with intractable pruritus. One patient also had severe cough. Nasobiliary drainage relieved pruritus in all patients and patient with cough also showed marked improvement within 24h. Nasobiliary drainage also hastened the recovery in these patients. CONCLUSIONS Short-term nasobiliary drainage should be considered in patients with cholestatic acute viral hepatitis with intractable pruritus and cough for symptomatic relief. It may help in faster recovery in these patients. However, a larger randomized controlled study is warranted.

Abstract
BACKGROUND & AIMS We tested the hypothesis that oral administration of bile salts, which are known to increase the biliary excretion of unconjugated bilirubin (UCB), decreases unconjugated hyperbilirubinemia in the Gunn rat model. METHODS Adult Gunn rats were fed a standard diet or the same diet supplemented with 0.5 weight % ursodeoxycholic acid (UDCA) or cholic acid (CA) for 1 or 6 weeks. UCB and urobilinoids, a family of intestinal UCB breakdown products, were determined in plasma, feces, or both. After 6 weeks of treatment, tracer 3H-UCB was administered intravenously to determine steady-state UCB kinetics over the next 60 hours. RESULTS One-week treatment with UDCA or CA decreased plasma UCB concentrations by 21% and 30%, respectively (each P < .01). During the first 4 days of treatment, both UDCA and CA increased the combined fecal excretion of UCB and urobilinoids (+52% and +32%, respectively; each P < .01). Prolongation of treatment to 6 weeks caused a persistent decrease in plasma UCB concentrations to approximately 40% below baseline (each bile salt P < .001). (3)H-UCB kinetic studies showed that UDCA and CA administration decreased UCB pool size (-33% and -32%, respectively; each P < .05) and increased UCB fractional turnover (+33% and +25%, respectively; each P < .05). CONCLUSIONS Dietary bile salt administration induces a large, persistent decrease in plasma UCB concentrations in Gunn rats. Both UDCA and CA enhance UCB turnover by increasing its fecal disposal. These results support the application of oral bile salt treatment in patients with unconjugated hyperbilirubinemia.

Abstract
OBJECTIVES Although ursodeoxycholic acid has been used to treat various cholestatic liver diseases in children, few data are available about its efficacy in biliary atresia. The aim of this study was to assess the effect of ursodeoxycholic acid treatment on liver function in children who underwent successful surgery for biliary atresia. PATIENTS AND METHODS We prospectively studied 16 children with biliary atresia who underwent successful portoenterostomies (postoperative conjugated bilirubin concentration: <34 micromol/L) and were treated with ursodeoxycholic acid for at least 18 months after surgery. Ursodeoxycholic acid treatment was then discontinued. Clinical and biological assessment was performed at the time of discontinuation of ursodeoxycholic acid treatment (T0), at follow-up (T1) and, if the clinical or biological status worsened, after resumption of ursodeoxycholic acid treatment (T2). RESULTS Ursodeoxycholic acid treatment was resumed in 13 cases. In 1 patient, jaundice recurred after ursodeoxycholic acid therapy was discontinued but abated after resumption of treatment. In 13 children, liver function worsened significantly when ursodeoxycholic acid was discontinued. T1 versus T0 concentrations expressed as multiples of the upper limit of the normal range (in parentheses) were as follows: alanine aminotransferase, 3.0 xN (0.8-7.0) vs 1.5 xN (0.5-5.4); gamma glutamyl transpeptidase, 8.0 xN (1.8-30.2) vs 4.2 xN (0.5-27.4); and aspartate aminotransferase, 1.7 xN (0.7-6.0) vs 1.3 xN (0.6-3.4). When ursodeoxycholic acid treatment was resumed, liver function had improved in all patients by T2. Concentrations of endogenous bile acids tended to be elevated at T1 (not significant) and were significantly decreased at T2. CONCLUSION Our study demonstrates the beneficial effect of ursodeoxycholic acid on liver function in children after successful surgery for biliary atresia.

Abstract
OBJECTIVES To investigate the effect of ursodeoxycholic acid (UDCA) in children with liver disease associated with ZZ alpha1-antitrypsin (AAT) deficiency. PATIENTS AND METHODS A total of 42 affected children received UDCA (30 mg x kg x day(-1)) and underwent clinical and biochemical follow-up at least yearly. RESULTS In group 1, 22 children whose mean initial gamma-glutamyl-transpeptidase (GGT) was 7.4 x N normalized serum liver test results after a mean treatment of 2.6 years. In 16 of these children, UDCA was discontinued. Relapse was observed in 11 children, and liver test results returned to normal after UDCA resumption. In the other 5 children, liver test results remained normal during a mean period of 2.5 years. In group 2, 11 children (mean initial GGT 12.8 x N) had improved liver test results after a mean treatment of 2.3 years. In group 3, 9 children (mean initial GGT 33.8 x N) had no liver test result improvement and evolution toward cirrhosis, requiring liver transplantation in 7. Most of the children in group 1 had normal results of clinical examination after UDCA treatment, versus none in group 3 (P < or = 0.00001). Initial GGT (P < or = 0.002) and total bilirubin (P < or = 0.05) levels were significantly lower in group 1 than in group 3. Combined initial values of GGT < or =5.5 x N and total bilirubin < or =66 micromol/L were associated with normalization of liver test results in 90% of children. CONCLUSIONS UDCA may significantly improve clinical status and liver test results in some children with liver disease associated with ZZ AAT deficiency. No beneficial effect of UDCA was shown in children with the most severe liver involvement. Initial levels of GGT and total bilirubin may be of prognostic value for therapy effectiveness.

We investigated the mechanism by which selected bile acids increase gut permeability using a validated in vitro model. Human intestinal Caco-2 cells were grown in monolayers and challenged with a panel of bile acids. Transepithelial electrical resistance and luminal-to-basolateral fluxes of 10-kDa Cascade blue-conjugated dextran were used to monitor paracellular permeability. Immunoprecipitation and immunoblot analyses were employed to investigate the intracellular pathway. Redistribution of tight junction proteins was studied by confocal laser microscopy. Micromolar concentrations of cholic acid, deoxycholic acid (DCA), and chenodeoxycholic acid (CDCA) but not ursodeoxycholic acid decreased transepithelial electrical resistance and increased dextran flux in a reversible fashion. Coincubation of 50 muM CDCA or DCA with EGF, anti-EGF monoclonal antibody, or specific src inhibitor 4-Amino-5-(4-chlorophenyl)-7-(t-butyl)pyrazolo[3,4-d]pyrimidine (PP-2) abolished the effect. A concentration of 50 muM of either CDCA or DCA also induced EGF receptor phosphorylation, occludin dephosphorylation, and occludin redistribution at the tight junction level in the same time frame and in a reversible fashion. We conclude that selected bile acids modulate intestinal permeability via EGF receptor autophosphorylation, occludin dephosphorylation, and rearrangement at the tight junction level. The effect is mediated by the src family kinases and is abolished by EGF treatment. These data also support the role of bile acids in the genesis of necrotizing enterocolitis and the protective effect of EGF treatment.

Abstract
'Idiopathic neonatal hepatitis' is a term that has traditionally been used to denote a clinical syndrome manifest by prolonged jaundice in the neonate. This description is now used much less frequently because recent studies unite well-defined clinical, biochemical and molecular features of intrahepatic cholestasis into specific syndromes. Advances in the understanding of the molecular basis of cholestatic syndromes now enable the classification of syndromes based on biology and offer an opportunity to develop new diagnostic approaches and treatment strategies that take into account the genetic make-up of the child with cholestasis.

Abstract
Altered bile flow physiology leads to many complications commonly seen in patients with cholestatic liver disease, regardless of the etiology. For each individual patient, a coordinated and effective treatment strategy must address the presence and the severity spectrum of malabsorption, malnutrition, vitamin and micronutrient deficiencies, pruritus, xanthomata, ascites, and liver failure, which are attributed directly or indirectly to diminished bile flow. An aggressive approach to maximizing the nutritional status of the child is vital to ensure optimal growth and development. Protein-calorie and/or fat supplementation is best discussed early. Decreasing the percentage of dietary long-chain triglycerides, providing medium-chain triglycerides, and ensuring adequate essential fatty acid and adequate protein intake may be helpful. Fat-soluble vitamin (A, D, E, and K) levels and micronutrient levels must be carefully and serially monitored and supplemented as necessary. Because the mechanisms that mediate pruritus of cholestasis remain to be determined, the use of empirical therapies continues to be standard practice. Ursodeoxycholic acid may ameliorate pruritus. Antihistamines and rifampicin may also provide temporary relief for some children. Based on the evidence that increased central opioidergic tone is present in chronic cholestasis, the use of opiate antagonists is promising but has not been evaluated in children. Selected patients with refractory pruritus that have failed maximal medical therapy have benefited from partial external biliary diversion. Ongoing dialogue with the family regarding the indications for liver transplantation is reasonable. Optimization and adherence with the pretransplant medical management enhance the chances for a successful outcome from liver transplantation. Specific to the pediatric patient, optimizing growth, development and nutrition, minimizing discomfort and disability, and aiding the child and family in coping with the stress, social, and emotional effects of chronic liver disease remain paramount.

Abstract
We report a case of Dubin-Johnson Syndrome in a neonate presenting with severe direct hyperbilirubinemia, which failed to respond to phenobarbital treatment. Ursodeoxycholic Acid added to therapy was well tolerated, and resulted in declining bilirubin concentration. We suggest ursodeoxycholic acid in treatment for Dubin-Johnson Syndrome with severe direct hyperbilirubinemia presenting in the neonatal age.

Abstract
Alagille syndrome (AGS) causes intractable pruritus and disfiguring xanthomas because of retained bile acids and cholesterol. This study was performed to determine whether partial external biliary diversion (PEBD) is effective for relief of pruritus and xanthomas in AGS patients who fail conventional medical therapy. Between the years 1985 and 2001, 9 AGS patients underwent PEBD. Complete follow-up data were available for all patients. The average age at PEBD was 4.8 (range 1.4-10) years. The average duration of follow-up was 7.5 (range 0.5-16.0) years. All 9 patients had severe, mutilating pruritus (grade 4) prior to diversion. At 1 year post-PEBD, the average pruritus score was 1.1; 8 patients had only mild scratching when undistracted. Three patients with extensive xanthomas prior to PEBD had complete resolution within 1 year. Mean serum bile salt levels (n = 5) decreased from 136.5 to 37.1 micromol/L and mean cholesterol (n = 7) from 724 to 367 mg/dL 1 year after PEBD. A single 21-year-old patient with PEBD for 14 years experienced an increase in pruritus from grade 1 to grade 4 within 2 months of elective reversal of PEBD. In conclusion, PEBD is effective for treating severe pruritus and hypercholesterolemia in AGS patients without cirrhosis who did not respond to medical therapy. PEBD should be considered as a therapeutic option for these patients before referral for liver transplantation because of morbid complications.

Abstract
The early detection of cholestatic liver disease is one of the major challenges facing pediatricians when evaluating the jaundiced infant. Early recognition of liver disease greatly facilitates the care and outcome of infants, because several serious life-threatening disorders may have cholestasis as a major presenting sign of underlying neonatal liver disease. A key component of the work-up is measurement of serum conjugated bilirubin levels, which if elevated should prompt the clinician to initiate a work-up to determine the cause of neonatal cholestasis. In general, if a patient is developing progressive jaundice soon after birth, is still jaundiced at 2 weeks of life, or develops jaundice within the first month of life, a work-up for neonatal cholestasis should begin. A number of previously undiagnosed causes of neonatal cholestasis are beginning to be assigned genetic and infectious etiologies, with significant implications for the work-up and management of cholestatic infants.

Abstract
In this study, we have investigated the effect of hydrophobic and hydrophilic unconjugated bile acids (UBAs)-ursodeoxycholic acid (UDCA), chenodeoxycholic acid (CDCA), lithocholic acid, and colic acid-on chemotaxis in adult and neonatal human polymorphonuclear leukocytes (PMNs). The trypan blue exclusion dye test was preliminarily performed to determine the toxicity of the studied UBAs on PMNs. N-formyl-methionyl-leucyl-phenylalanine (100 nM) was used as a chemoattractant. Chemotaxis (1 x 10(6)cells/mL) was analyzed in the presence or absence of UBAs (10 microM) by blind well chambers. The antioxidants vitamin E and vitamin C were tested for their ability to reduce the inhibitory effect of UBAs. We found that only CDCA was able to induce damage in PMNs in the range of 1-40 microM. Both CDCA and UDCA were able to inhibit chemotaxis in PMNs, whereas lithocholic acid and colic acid were ineffective. The inhibitory effect was reversible inasmuch as PMNs incubated with either CDCA or UDCA and subsequently washed showed normal chemotaxis. Concomitant incubation of PMNs with UBAs and vitamins C or E reversed the inhibition. We did not find substantial differences between PMNs from adults or newborns. In conclusion, CDCA and UDCA are able to reduce, in a specific and reversible fashion, both adult and newborn neutrophil chemotaxis. As concomitant incubation of UBAs and electron scavengers restores PMN chemotaxis to control values, we conclude that free radicals may be involved in the mechanism of inhibition. We speculate that this defect may contribute to the impaired host response described in cholestatic patient.

Abstract
Identification, evaluation and treatment of liver disease are increasingly important challenges in children with cystic fibrosis (CF). Liver disease usually presents at puberty and is receiving more attention with improved life expectancy. The abnormal CF transmembrane regulator protein in the apical surface of the biliary epithelium causes the disease. Hyperviscous bile accumulates in the biliary tree causing cholangiocyte and hepatocyte injury, stimulating focal fibrosis. Fibrosis is thought to lead on to cirrhosis over a period of years, a process which is usually asymptomatic. Steatosis and biliary tree anomalies including cholecystitis also occur. Clinical signs of liver disease appear late, by which time cirrhosis may be established. Early diagnosis would allow interventions to be evaluated but there is no gold standard for screening. Currently, regular clinical assessment, measurement of liver enzymes, ultrasound and liver biopsy are all used to evaluate liver disease in CF. Bile acid therapy reverses many markers of the disease but there is no good evidence that progression to cirrhosis can be prevented. A few children with cirrhosis decompensate (demonstrated by falling plasma albumin or coagulopathy) but they do well with liver transplantation. Children with portal hypertension as the sole manifestation of CF liver disease can be effectively managed with a programme of variceal obliteration or porto-systemic shunts.

Abstract
BACKGROUND The objective of the study was to determine whether ursodeoxycholic acid (Ursodiol) is protective against ibuprofen (IBU)-induced enteropathy. METHODS Using the chronically catheterized rat model, IBU (60 mg/kg body weight per day) was infused via the gastric catheter twice daily. Pancreatic enzyme (PE; 10,000 U lipase/kg body weight per day) and Ursodiol (10 mg/kg body weight per day) in two doses were infused via the duodenal catheter. Rats were assigned to one of six treatment groups and were administered treatment for 20 days: control, IBU, PE, IBU + PE, IBU + Ursodiol, and IBU + PE + Ursodiol. The entire jejunum, ileum, cecum, and colon were available for histologic analysis using previously described techniques. RESULTS Addition of Ursodiol to high-dose IBU and normal doses of PE showed a significant reduction in the percentage of rats with ulcers (P < 0.05), total number of serositis events (P < 0.01), total number of severe ulcers (P < 0.001), and an absence of ulcers in the large intestine. CONCLUSIONS Ursodiol, the drug of choice for the treatment of cystic fibrosis liver disease, may offer a safe method of using high-dose IBU in these patients by ameliorating the enteropathy.

Abstract
BACKGROUND Ursodeoxycholic acid (UDCA) has been shown to be beneficial in reducing disease activity in adult patients with primary sclerosing cholangitis (PSC). However, there has been little published regarding PSC in children and no studies investigating the efficacy of UDCA as a treatment for PSC. METHODS This retrospective study included 10 children who were found to have the diagnosis of PSC during the past 15 years at the Texas Children's Hospital and Herman Hospital, both in Houston, Texas. The male:female ratio was 8:2, the median age of onset was 12 years (range, 1-17 years), and eight patients had coexistent inflammatory bowel disease (IBD; six ulcerative colitis, one Crohn's disease, one unspecified). At the time of diagnosis, five patients were asymptomatic, all of whom had IBD with elevated liver enzymes and three of whom had hepatomegaly. Nine patients were treated with UDCA. The one patient who did not receive UDCA was lost to follow-up soon after diagnosis. The mean dose of UDCA was 17 mg/kg with the doses ranging from 9 to 37 mg/kg. RESULTS There were no side effects from the medication recorded for any of the patients. These patients showed a significant reduction in alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase at 1, 3, 6, 15, and 20 months after treatment. CONCLUSIONS This study demonstrates that children with PSC treated with UDCA have significant improvements in liver biochemical indices. However, the long-term effect of UDCA on clinical outcome is unknown.

Abstract
BACKGROUND Chronic intrahepatic cholestasis is associated with severe pruritus that is often refractory to maximal medical management and leads to significantly impaired quality of life. The hypothesis in this study was that partial external biliary diversion (PEBD) can substantially improve intractable pruritus secondary to intrahepatic cholestasis with subsequent improvement of functional quality of life. METHODS Parents' and/or patients' clinical rating of pruritus, growth percentiles, biochemical parameters, and liver biopsies performed before and after surgery were compared in a retrospective medical record review. RESULTS Eight children underwent PEBD from 1990 through 1997. Complete follow-up data were available for seven patients. Before surgery, all patients had intense pruritus, which was not responsive to maximal medical therapy. Specimens obtained in preoperative liver biopsies showed moderate (n = 1), minimal (n = 6), or no (n = 1) portal fibrosis. After PEBD, all patients received ursodeoxycholic acid (10-15 mg/kg/dose two to three times daily) until resolution of pruritus. Of the seven patients with complete follow-up data, six had complete resolution of pruritus and sustained resolution up to 8 years after surgery. The patient with mild to moderate residual pruritus was the youngest to undergo PEBD. Growth improved from below the 5th percentile before surgery to the 5th through the 25th percentiles for five of six patients with more than 6 years' follow-up. All families reported improved quality of life, defined by school attendance and ability to resume normal activity with peers. There has been no clinical evidence of progression of liver disease. CONCLUSION Partial external biliary diversion is effective in the long-term treatment of pruritus refractory to medical therapy and provides a favorable outcome in a select group of patients with chronic intrahepatic cholestasis without cirrhosis.

Abstract
A 21-month-old girl suffering from tyrosinaemia type I and undergoing treatment with 2-(2-nitro-4-trifluoro-methylbenzoyl)-1,3-cyclohexanedione (NTBC) presented with pruritus which rapidly ceased with administration of high doses of ursodeoxycholic acid. Determination of plasma bile acids revealed clearly elevated levels both in samples taken before and after the onset of NTBC therapy, thus indicating, that the increase was not related to the administration of this drug. This result is corroborated by data from the first patient's newborn sister, diagnosed with the same disease, who showed elevated plasma bile acid concentrations in all samples examined, except for the cord plasma. This is the first report on altered bile acid concentrations in tyrosinaemia type I, and underlines the need for thorough investigation of bile acid metabolism in this disease.

Abstract
Treating a pediatric patient offers a unique opportunity to develop effective strategies to prevent progressive liver injury and to develop novel therapeutic regimens to reduce the need for OLT. Universal vaccination against hepatitis viruses will prevent cirrhosis and liver cancer. Education and counseling may reduce the incidence of alcoholic liver disease. Precise and early screening for metabolic liver disease and genetic or targeted therapy may prevent disease progression. A retrospective look at the 1983 National Institutes of Health Consensus Conference on Liver Transplantation, after more than 15 years of experience among many centers, indicates that liver transplantation can be effectively used to childhood liver disease. Projections 10 years into the future offer hope that liver transplantation may not be needed in the treatment of certain diseases such as metabolic liver disease and fulminant hepatic failure. Focusing on prevention or treatment of liver disease in early life, thoughtful medical management, precise decision making, and conscientious, creative, and courageous use of nontransplant options, can save both livers and lives.

Abstract
BACKGROUND/OBJECTIVE Parenteral nutrition is an integral part of the care of premature infants. Cholestatic liver disease is a frequent complication of prolonged parenteral nutrition, especially in premature infants. It has been suggested that ursodeoxycholic acid may alter the course of parenteral nutrition-associated cholestasis in children and adults. We attempted to determine the efficacy of ursodeoxycholic acid in premature infants with parenteral nutrition-associated cholestasis. METHODS Retrospective chart review of all infants receiving ursodeoxycholic acid for parenteral nutrition-associated cholestasis in a 40 bed neonatal intensive care unit. Efficacy of ursodeoxycholic acid was evaluated by response of bilirubin, alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase over a treatment period of at least 1 month. RESULTS Six infants with parenteral nutrition-associated cholestasis who had received ursodeoxycholic acid for one month were identified. Doses of ursodeoxycholic acid ranged from 15-30 mg/kg/day. Cholestasis appeared at a mean age of 47 +/- 17 (mean +/- SD) days after a mean of 42 +/- 15 days of parenteral nutrition. Transaminase levels decreased in three, and either increased or did not change in the other three infants. Bilirubin levels decreased in all infants. Alkaline phosphatase showed a non significant trend to decreased levels. Consistent improvement in all infants was noted only after 10 days of full enteral nutrition. No toxicity was found during ursodeoxycholic acid treatment. CONCLUSIONS Ursodeoxycholic acid treatment in premature infants appears to be safe, and leads to an early sustained decrease in bilirubin levels by two weeks of therapy. The response of transaminase levels was not sustained in our small cohort.

Abstract
Ursodeoxycholic acid (UDCA) improves liver enzymes and in many instances liver histology in cholestatic liver diseases such as primary biliary cirrhosis and primary sclerosing cholangitis. Besides classic cholestatic diseases, UDCA also improves liver biochemistry in alcoholic liver disease and in chronic viral hepatitis C. The main target of UDCA treatment, however, is cholestasis, and consequently the mechanisms responsible for the beneficial effects in these diseases are of interest, and are discussed in detail in this article.
