Abstract
BACKGROUND AND STUDY AIMS Biliary atresia (BA) is the most common cause of neonatal cholestasis, negatively affecting nutritional status, growth, and development. It is the most frequent paediatric indication for liver transplantation. The Kasai portoenterostomy (KPE) operation is an effective procedure with favourable outcomes when performed before two months of age. The present study aimed to assess the nutritional status of patients with biliary atresia who underwent the Kasai operation and to evaluate the effectiveness of nutritional counselling using medium-chain triglyceride (MCT) formulas and proper supplementation on their nutritional status, growth, and vitamin D levels. PATIENTS AND METHODS This prospective observational study included 36 infants with biliary atresia who underwent Kasai portoenterostomy. All patients underwent clinical assessment, anthropometric evaluation, nutritional counselling, and an evaluation of vitamin D levels. Only compliant patients (22/36) were followed up after 3 and 6 months of nutritional counselling. RESULTS Z-scores for weight, triceps skinfold thickness, and mid-upper arm circumference improved significantly after three months, and the height velocity Z-score improved after six months of nutritional counselling using an MCT-containing formula and supplementations. Patients who showed an improvement in cholestasis had better responses. The initial assessment revealed low serum levels of 25-hydroxyvitamin D in 77.8 %, which increased significantly (p = 0.012). CONCLUSION Dietary intervention and supplementation with MCT and micronutrients can improve the nutritional status of children with BA following KPE.

Abstract
BACKGROUND Vitamin D deficiency in patients with cholestasis is due to impaired intestinal vitamin D absorption, which results from decreased intestinal bile acid concentration. Patients with cholestasis usually do not achieve optimal vitamin D status when a treatment regimen for children without cholestasis is used. However, data on high-dose vitamin D treatment in patients with cholestasis are limited. METHODS This study is a prospective study that included pediatric patients with cholestasis (serum direct bilirubin > 1 mg/dL) who had vitamin D deficiency (serum 25-hydroxyvitamin D, 25-OHD, < 20 ng/mL). In Phase 1, single-day oral loading of 300,000 IU (or 600,000 IU if weight ≥ 20 kg) of vitamin D2 was administered, followed by an additional loading if serum 25-OHD < 30 ng/mL, and 4-week continuation of treatment using a vitamin D2 dose calculated based on the increment of 25-OHD after first loading. In Phase 2, oral vitamin D2 (200,000 IU/day) was administered for 12 days, followed by 400,000 IU/day of vitamin D2 orally for another 8 weeks if serum 25-OHD < 30 ng/mL. RESULTS Phase 1: Seven patients were enrolled. Three out of seven patients had a moderate increase in serum 25-OHD after loading (up to 20.3-27.2 ng/mL). These patients had conditions with partially preserved bile flow. The remaining four patients, who had biliary atresia with failed or no Kasai operation, had low increments of serum 25-OHD. Phase 2: Eleven patients were enrolled. Eight out of 11 patients had a moderate increase in serum 25-OHD after 200,000 IU/day of vitamin D2 for 12 days. Serum 25-OHD continued increasing after administering 400,000 IU/day of vitamin D2 for another 8 weeks, with maximal serum 25-OHD of 15.7-22.8 ng/mL. CONCLUSION Very high doses of vitamin D2 (200,000 and 400,000 IU/day) partly overcame poor intestinal vitamin D absorption and resulted in moderate increases in serum 25-OHD in pediatric patients with cholestasis, particularly when cholestasis was caused by uncorrectable bile duct obstruction.

Abstract
Vitamin D (calciferol) is a fat-soluble vitamin that has a significant role in phospho-calcium metabolism, maintaining normal calcium levels and bone health development. The most important compounds of vitamin D are cholecalciferol (vitamin D3, or VD3) and ergocalciferol (vitamin D2, or VD2). Besides its major role in maintaining an adequate level of calcium and phosphate concentrations, vitamin D is involved in cell growth and differentiation and immune function. Recently, the association between vitamin D deficiency and the progression of fibrosis in chronic liver disease (CLD) was confirmed, given the hepatic activation process and high prevalence of vitamin D deficiency in these diseases. There are reports of vitamin D deficiency in CLD regardless of the etiology (chronic viral hepatitis, alcoholic cirrhosis, non-alcoholic fatty liver disease, primary biliary cirrhosis, or autoimmune hepatitis). Vitamin D binding protein (VDBP) is synthesized by the liver and has the role of binding and transporting vitamin D and its metabolites to the target organs. VDBP also plays an important role in inflammatory response secondary to tissue damage, being involved in the degradation of actin. As intense research during the last decades revealed the possible role of vitamin D in liver diseases, a deeper understanding of the vitamin D, vitamin D receptors (VDRs), and VDBP involvement in liver inflammation and fibrogenesis could represent the basis for the development of new strategies for diagnosis, prognosis, and treatment of liver diseases. This narrative review presents an overview of the evidence of the role of vitamin D and VDBP in CLD, both at the experimental and clinical levels.

Abstract
BACKGROUND Infants with cholestasis are at risk of fat-soluble vitamin deficiency. The present study amied to review practice relating to the assessment, deficiency and supplementation of fat-soluble vitamins in infants with cholestasis. METHODS The medical records of all newly diagnosed infants with cholestasis (conjugated bilirubin >17 mmol L-1 />20% total bilirubin) at King's College Hospital between 2017 and 2019 were reviewed. Data extracted included bilirubin, serum vitamin concentrations (A, D, E), international normalised ratio and evidence of supplementation at initial assessment, as well as at 3 and 6 months. Rates of vitamin assessment, deficiency and supplementation were compared using chi-squared or Fisher's exact test. RESULTS In total, 136 infants (87 male) with idiopathic neonatal cholestasis (n = 62), biliary atresia (n = 40) and other aetiology (n = 34) were included. Assessment of serum vitamins (A, D, E) was low (33.3%-52.2%) and deficiency was initially high for vitamin D (60.6%) and vitamin E (70.9%). Supplementation prevalence at initial assessment was high (A, E, K), but dropped significantly at 3 and 6 months for vitamin E (p = 0.003) and vitamin K (p = 0.001), whereas vitamin D supplementation was consistently low throughout (25%-33.3%). Infants with biliary atresia were more likely to have vitamins assessed (3 months), be deficient initially (D, E) and supplemented (E, K) throughout. Supplementation continued in up to 80% of infants despite cholestasis resolving. CONCLUSIONS Supplementation was generally high and continued in many despite cholestasis resolving. Deficiency of vitamin D and vitamin E was high at initial assessment, although lower at follow-up. Actual prevalence of deficiency of all vitamins is unknown because monitoring was not consistently performed.

Abstract
To investigate the mechanism of 25 hydroxyvitamin D (25(OH)D) deficiency in children with biliary atresia (BA) and its effect on liver fibrosis. The serum vitamin D and 25(OH)D, and expression of 25 hydroxylase (CYP2R1 and CYP27A1) in the liver of BA patients were detected and compared with those in the control group. We investigated the effect of differential expression of CYP2R1 in hepatocytes on the expression of genes related to liver fibrosis in primary hepatic stellate cells (HSCs) of BA and animal models of cholestasis. The ratio of 25(OH)D/vitamin D in the BA group was significantly lower than that in the control group. The mRNA and protein expression of CYP2R1 and CYP27A1 in liver tissue of the BA group was significantly lower than that in the control group. Exogenous active vitamin D (calcitriol) inhibited the proliferation and migration of primary HSCs isolated from BA patients, and reduced the expression of fibrosis-related genes in vitro. Downregulation of expression of CYP2R1 in hepatocytes increased expression of transforming growth factor (TGF)-β1, collagen (Col)-1α1 and tissue inhibitor of metalloproteinase (TIMP)-1, and decreased the expression of matrix metalloproteinase (MMP)-2 in cocultured primary HSCs of BA. Upregulation of expression of CYP2R1 in mice with bile duct ligation significantly increased the level of 25(OH)D, decreased the expression of TGF-β1, Col-1α1 and TIMP-1, and increased the expression of MMP-2. Children with BA have impaired vitamin D activation due to CYP2R1 deficiency. The dysactivation of vitamin D can promote the proliferation and activation of HSCs and participate in the development of hepatic fibrosis in BA.

Abstract
Portoenterostomy (PE) has remained as the generally accepted first line surgical treatment for biliary atresia (BA) for over 50 years. Currently, close to half of BA patients survive beyond 10 years with their native livers, and most of them reach adulthood without liver transplantation (LT). Despite normalization of serum bilirubin by PE, ductular reaction and portal fibrosis persist in the native liver. The chronic cholangiopathy progresses to cirrhosis, complications of portal hypertension, recurrent cholangitis or hepatobiliary tumors necessitating LT later in life. Other common related health problems include impaired bone health, neuromotor development and quality of life. Only few high-quality trials are available for evidence-based guidance of post-PE adjuvant medical therapy or management of the disease complications. Better understanding of the pathophysiological mechanisms connecting native liver injury to clinical outcomes is critical for development of accurate follow-up tools and novel therapies designed to improve native liver function and survival.

Abstract
Objectives: T-cell mediated rejection (TCMR) can compromise long-term liver allograft survival. The immunomodulatory properties of vitamin D are increasingly recognized. We investigated whether perturbations in vitamin D metabolism prior to LT may predispose to TCMR in a representative cohort of paediatric LT recipients. Methods: In this retrospective single-center study of children who underwent liver transplantation between 2005 and 2017, we collected serum 25(OH) vitamin D levels and other parameters related to vitamin D metabolism. Post-transplant variables were collected from medical records during the first year following LT. Results: Eighty-two patients were included. Twenty-six (32%) developed TCMR, 52 (65%) presented at least one event of 25(OH) D insufficiency during the year before the transplant, while 23 (32%) had at least one documented elevated plasma parathyroid hormone level. Forty-six patients benefited from nutritional support (56%). The development of TCMR was associated with vitamin D insufficiency pre-LT (p = 0.01). No significant correlations were identified between PTH levels and incidence of TCMR. The association was stronger in patients transplanted for cholestatic diseases (p = 0.004). Conclusions: Vitamin D insufficiency before a liver transplant may be associated with TCMR during the first year post-LT. These findings warrant further investigation.

Abstract
Hungry bone syndrome is a rare but potentially lethal complication that is characterized by rapid, severe, long-lasting hypocalcemia and hypophosphatemia secondary to increased bone metabolism. We present a case of hungry bone syndrome after living donor liver transplant for biliary atresia. Following a failed Kasai procedure for biliary atresia, a 5-month-old boy underwent living donor liver transplant with reduced left lateral lobe from his father. Despite the oral administration of alfacalcidol, the patient exhibited severe craniotabes before the surgery. He developed severe hypocalcemia and hypophosphatemia im-mediately after liver transplant and required supplementation of calcium and phosphorus for 1 month thereafter. After serum levels of calcium and phosphate had normalized, there was a rapid increase in the serum bone-type alkaline phosphatase level, and the craniotabes subsided remarkably. To our knowledge, this is the world's first reported case of hungry bone syndrome after liver transplant for cholestatic cirrhosis. It underscores the importance of strict nutritional and electrolyte management in the perioperative period. A prompt diagnosis and correction of hungry bone syndrome are imperative to prevent the associated significant morbidity and mortality.

Abstract
OBJECTIVES The aim of the study was to examine the frequency of rickets and bone fractures and to assess areal bone mineral density (aBMD) in childhood among patients with biliary atresia (BA). METHODS We gathered data on all patients diagnosed with BA in Finland that survived to ≥1 year of age between 1 January 2000 to 30 June 2018. Data on gestational age, birth weight, postsurgical medications, and history of rickets and bone fractures were collected retrospectively. Serum levels of 25-hydroxyvitamin D [25(OH)D] postportoenterostomy (PE) were collected. Plain radiographs and dual energy X-ray absorptiometry (DXA) measurements of study subjects were reviewed. RESULTS Out of 49 patients, 7 (14%) were diagnosed with rickets during infancy. Clearance of jaundice [odds ratio 0.055, 95% confidence interval [CI] 0.00266-0.393; P < 0.01] was a protective factor against rickets. Sufficient 25(OH)D levels were reached 3 months post-PE. Eleven (22%) patients suffered at least one bone fracture (range 1-9) during childhood and adolescence. In DXA measurements, median lumbar spine aBMD anthropometrically adjusted z-scores were as follows: in native liver survivors 0.8 (interquartile range [IQR] -1.9 to 1.4) at 5 and -0.3 (IQR -1.3 to 0.8) at 10 years and for liver transplanted patients 0.4 (IQR -0.2 to 1.1) at 5 and 0.6 (IQR -0.1 to 1.3) at 10 years. CONCLUSIONS BA patients have an increased risk for rickets and bone fractures compared with the normal population. Most BA patients have aBMD within normal range between 5 and 10 years of age irrespective of liver transplantation status.

Abstract
The treatment of biliary atresia (BA) is predominantly surgical with firstly an attempt at restoration of bile flow from the native liver by wide excision of the obstructed, obliterated extrahepatic biliary tree to the level of the porta hepatis and a portoenterostomy using a long Roux loop-Kasai portoenterostomy (KPE). Liver transplantation is reserved for those that fail this and for those where surgery is considered futile for reasons of age or stage of disease. As the aetiology of BA remains ill-defined, so adjuvant treatment has been largely based on pragmatism, trial and error. Systematic analysis of the few randomized placebo-controlled trial data and less well-controlled cohort studies have suggested benefit from post-operative high-dose steroids and ursodeoxycholic acid (UDCA) while the benefit of long-term prophylactic antibiotics, bile acid sequestrants (e.g., colestyramine) or probiotics remains unproven. Newer modalities such as antiviral therapy (AVT), immunoglobulin, FXR agonists (e.g., obeticholic acid), ileal bile acid transporter (IBAT) antagonists (e.g., maralixibat) remain unproven. This article reviews the current evidence for the efficacy of adjuvant medical therapy in BA.

[PMID: 31781188 PMCID: PMC6875370 DOI: 10.1155/2019/4621372] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2019] [Revised: 08/19/2019] [Accepted: 09/13/2019] [Indexed: 02/06/2023] Open
Abstract
Objectives To detail the effects of vitamin D (VD) deficiency and assess the relationships between VD deficiency and liver function and liver fibrosis in patients with biliary atresia (BA). Methods In this study, BA patients confirmed by intraoperative cholangiography were enrolled between January 2017 and February 2019. Preoperative serum 25-(OH)D level, liver function, serum biomarker levels of liver fibrosis, and histopathologic features were recorded. Deficiency, insufficiency, and sufficiency of VD were defined as serum 25-(OH)D concentrations of <10, 10-20, and >20 ng/ml, respectively. Associations between serum 25-(OH)D level and liver function and liver fibrosis were analyzed. Results A total of 161 BA infants were included. The median (interquartile range (IQR)) serum 25-(OH)D level in all patients was 7.56 (IQR: 4.48–11.40) ng/ml. The rates of 25-(OH)D deficiency, insufficiency, and sufficiency were 67.1% (108/161), 29.2% (47/161), and 3.7% (6/161), respectively. Serum 25-(OH)D level was negatively correlated with alkaline phosphatase (r = ‐0.232, P = 0.003). After adjusting for age, a decrease in serum 25-(OH)D level was correlated with the increase of the Batts-Ludwig stage score (odds ratio (OR): 0.94, 95% confidence interval (CI): 0.88–0.99; P = 0.028). Serum 25-(OH)D level was also correlated with the N-terminal propeptide of type III procollagen (PIIINP) (r = ‐0.246, P = 0.002). Additionally, PIIINP (P = 0.038) and ALP (P = 0.031) were independently associated with serum 25-(OH)D level. Conclusions VD deficiency was common and inversely correlated with liver fibrosis in BA patients. Furthermore, VD was not correlated with liver function except alkaline phosphatase.

Serum vitamin D level is inversely associated with liver fibrosis in post Kasai's portoenterostomy biliary atresia patients living with native liver. PLoS One 2019; 14:e0218896. [PMID: 31242241 PMCID: PMC6594627 DOI: 10.1371/journal.pone.0218896] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Accepted: 06/11/2019] [Indexed: 01/01/2023] Open
Abstract
Objective This study aims to investigate the association of serum vitamin D (VD) levels with the severity of liver fibrosis (LF) in post Kasai’s portoenterostomy biliary atresia (PKBA) patients living with their native liver. Methods In this cross-sectional study, carried out in a tertiary Children’s Hospital in Taipei, Taiwan, PKBA patients living with their native liver were enrolled. Liver biochemistry data, serum 25-hydroxyvitamin D (25-OHVD), acoustic radiation force impulse (ARFI), and scores of Pediatric Quality of Life questionnaire (PedsQL) were collected. Results All the enrolled 33 PKBA patients (36.4% males), aged 1–23 years, possessed 25-OHVD less than 30ng/ml. An inverse correlation was detected between serum 25-OHVD and ARFI (r2 = 0.175; p = 0.024). We selected a cutoff value of 23ng/mL to divide PKBA patients into two groups, as the p-value was the most significant at this point when comparing the median ARFI of two groups (p = 0.003). Ten (30.3%) had 25-OHVD≥23ng/ml (HVD group), whereas 23(69.7%) had 25-OHVD<23ng/ml (LVD group). HVD group had lower ARFI (1.13m/s vs. 1.52m/s, p = 0.003), lower aspartate transaminase (AST) (29U/L vs. 64U/L, p = 0.033), and higher scores of self-reported health-related quality of life in psychosocial functioning (86.7 vs. 77.1, p = 0.047) than LVD group. Conclusion VD levels are inversely associated with severity of LF in PKBA patients with native liver.

Abstract
OBJECTIVE To explore the preoperative nutrition status in patients with biliary atresia (BA) and its effect on the cholangitis of Kasai portoenterostomy (KPE). METHODS 106 patients who had been diagnosed with BA type III and were undergoing KPE were divided into two groups according to the score obtained using STRONGkids. Preoperative and postoperative data were collected to compare general characteristics and postoperative outcomes between the different groups. RESULTS Forty-nine (46.2%) patients were at moderate nutritional risk (MNR) and fifty-seven (53.8%) patients were at high nutritional risk (HNR) preoperatively. The MNR group had shorter postoperative hospitalization times than the HNR group (P = 0.023). The initial postoperative cholangitis occurred later (P = 0.002) and the incidence of early cholangitis was lower (P = 0.029) in patients at MNR than in those at HNR. The ratio of jaundice clearance (P = 0.02) and 2-year native liver survival (P = 0.0109) were significantly higher in MNR group than in HNR group. CONCLUSIONS Patients with BA presented the greatest nutritional deficiencies and patients at HNR are more vulnerable to the early cholangitis and the rate of jaundice clearance is lower than those at MNR. The occurrence of initial postoperative cholangitis in MNR group was later than in HNR group.

Fat-Soluble Vitamin Deficiency in Pediatric Patients with Biliary Atresia. Gastroenterol Res Pract 2017; 2017:7496860. [PMID: 28690638 PMCID: PMC5485346 DOI: 10.1155/2017/7496860] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2017] [Accepted: 05/07/2017] [Indexed: 02/06/2023] Open
Abstract
Objective To analyze the levels of fat-soluble vitamins (FSVs) in pediatric patients with biliary atresia (BA) before and after the Kasai procedure. Methods Pediatric patients with obstructive jaundice were enrolled in this study. The FSV levels and liver function before, 2 weeks after, and 1, 3, and 6 months after the Kasai procedure were measured. Results FSV deficiency was more obvious in patients with BA than in patients with other cholestatic liver diseases, especially vitamin D deficiency. 25-Hydroxy vitamin D (25-(OH)D) deficiency was more pronounced in younger patients before surgery. The 25-(OH)D level was significantly higher in patients with than without resolution of jaundice 3 months after surgery. At 6 months after surgery, the 25-(OH)D level was abnormally high at 8.76 ng/ml in patients with unresolved jaundice. Conclusions Preoperative FSV deficiency, particularly vitamin D deficiency, is common in patients with BA. 25-(OH)D deficiency is more pronounced in younger children before surgery. Postoperative FSV deficiency was still prevalent as shown by the lower 25-(OH)D levels in patients with BA and unresolved jaundice. This required long-term vitamin AD supplementation for pediatric patients with BA and unresolved jaundice after surgery.
