Management of neonatal cholestasis: Consensus statement of the pediatric gastroenterology chapter of Indian academy of pediatrics

Nutrition in Pediatric Liver Disease

In liver disease, there is derangement of appetite, digestion, absorption, assimilation, storage and metabolism of both macro and micronutrients. These derangements have an impact on mortality and morbidity associated with liver diseases. In infants, breast feeds should not be stopped unless there are compelling reasons such as underlying metabolic problem. Parenteral nutrition should be considered only if, oral or nasogastric feeding is not possible. The effect of malnutrition on liver disease and impact of liver failure on nutrition is vicious and nutritional intervention has to be done at the earliest to break that vicious cycle. This chapter gives an overview of nutritional management in acute and chronic liver diseases in children and also its impact on specific clinical scenarios including liver transplantation.

Comparison of Liver Transplant Outcomes in Biliary Atresia Patients, Considering Whether They Underwent the Kasai Procedure Beforehand: A Single Center Analysis of 72 Patients

BACKGROUND

This study examines the results of liver transplantation (LT) in patients with biliary atresia, considering whether they underwent the Kasai procedure beforehand. LT and determine postoperative and long-term graft outcomes.

METHODS

This single-center, retrospective study included 72 pediatric patients diagnosed with postpartum biliary atresia who underwent LT between 2010 and 2022. We included patients who underwent LT either after or without the Kasai procedure and compared the demographic data of the patients with various factors, such as the Pediatric End-Stage Liver Disease scores and laboratory values.

RESULTS

The study included 72 patients, with 39 of them being female (54.2%) and 33 of them being male (45.8%). Of the 72 patients in the study, 47 (65.3%) had undergone the Kasai procedure, and 25 (34.7%) had not. The preoperative and postoperative month 1 bilirubin values were lower in patients who underwent the Kasai procedure and were higher in postoperative months 3 and 6. Preoperative bilirubin values, postoperative month 3 bilirubin values, and preoperative albumin values were higher in patients who developed mortality (P < .05). Cold ischemia time was longer in patients who developed mortality (P < .05).

CONCLUSIONS

Our study showed a higher mortality rate in patients who underwent the Kasai procedure. The results also showed that LT was more effective in children, as patients with Kasai had higher mean bilirubin values and higher preoperative albumin values than patients without Kasai.

Shear Wave Elastography: A Reliable Secondary Parameter for Diagnosing Biliary Atresia in Infants With Neonatal Cholestasis

Objective In this study, we aimed to optimize various grayscale, Doppler, and elastography parameters and evaluate their diagnostic performance in the preoperative diagnosis of biliary atresia (BA). Materials and methods A total of 158 infants aged <6 months with neonatal cholestasis (NC) were enrolled in the study and sonography was performed after four hours of fasting. For comparison of elastography, 31 exclusively age-matched controls, not suffering from liver disease, were included separately. Triangular cord and gallbladder (GB) parameters were considered as primary parameters, while right hepatic artery (RHA) caliber, RHA-to-right portal vein (RPV) ratio, hepatic subcapsular flow (HSF), and shear wave elastography (SWE) were considered as secondary parameters. Diagnosis of infants with BA was confirmed on histopathology. Data were presented as mean ±standard deviation (SD) and frequency. Differences between groups were compared using the Chi-square test and the unpaired student t-test. Receiver operating characteristic (ROC) curve analysis was done for individual ultrasound/Doppler/SWE parameters to calculate the optimal cutoff value. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated for each parameter and their combinations. Results Of the primary parameters, GB contractility index (CI) and length showed the highest sensitivity and specificity respectively. A cutoff of 14 kPA was derived for SWE for the diagnosis of BA. Among secondary parameters, SWE had the best diagnostic performance, better than even the individual primary parameters. A combination of primary parameters with SWE in series showed the highest accuracy. Conclusion Among secondary parameters, elastography can prove to be highly useful. The highest accuracy in diagnosing BA can be obtained by combining primary parameters with SWE.

Effect of Phenobarbital on Elevated Direct Bilirubin Concentrations in Neonates and Infants in the Neonatal Intensive Care Unit

OBJECTIVE

Few studies have evaluated the effect of phenobarbital (PB) on elevated direct bilirubin (DB) plasma concentrations in neonates and infants, and none have compared its effect with a control group with matched study baseline DB values. The purpose of this study was to quantify changes in elevated DB plasma concentrations (≥2 mg/dL) in neonates and infants between a PB-treated and control group.

METHODS

A retrospective, observational, matched, cohort study was performed comparing patients between a PB-treated group and a control group with similar study baseline plasma DB values ≥2 mg/dL over an 8-week period. The percent change in DB plasma concentrations from study baseline was compared for each week of the study period.

RESULTS

During the 8-year study period, 310 patients had DB plasma concentrations ≥2 mg/dL, of which 26 remained in each group after exclusions. The PB group had increased DB concentrations and the control group had decreased DB concentrations when compared with their study baseline DB concentrations each week of the study period. By study end, the mean DB concentration increased by 11.2% in the PB group and decreased by 48.5% in the control group (p = 0.02). In multiple regression analysis, only birth weight (standardized coefficient = 0.44, p = 0.02), and gastrointestinal obstruction (standardized coefficient = −0.4, p = 0.03) were associated with significant percent change in DB concentrations.

CONCLUSIONS

This study demonstrated PB does not improve cholestasis in neonates and infants.

Neonatal Cholestasis: The Changing Etiological Spectrum in Pakistani Children

Objectives: To determine the frequency of clinical presentation and laboratory profile in the diagnosis of the etiological spectrum of neonatal cholestasis.

Material and methods: In this prospective cross-sectional study, we recruited children who presented with jaundice and direct hyperbilirubinemia with onset in the first three months of life. The study was conducted between April 2019 to March 2021 (24 months) at the Government Lady Reading Hospital of Khyber Pakhtunkhwa province in Pakistan. The diagnosis was based on history and clinical findings that included jaundice, stool color, itching, abdominal distention, and deranged liver function tests and confirmed on liver biopsy and specific diagnostic tests. Data was recorded and analyzed using SPSS version 20 (IBM Corp., Armonk, NY).

Results: A total of 90 children were included in the study, out of which 65.6% were male. The average age was recorded as 118.01 days + 118.1 SD. Jaundice, dark urine, and hepatomegaly were found in 85.6% of children while ophthalmologic disorder, congenital heart disease, and itching were the least common symptoms. Laboratory findings of the cholestasis patients showed high bilirubin (mean: 8.88 mg/dL), alanine transaminase (ALT) (mean: 177.48 IU/mL), aspartate transaminase (AST) (mean: 187.11 IU/mL), gamma-glutamyl transpeptidase (GGT) (mean: 187.66 IU/mL) and prolonged international normalized ratio (INR) (mean: 2.20) in majority of patients. The genetic and metabolic disorder was the leading cause found in the majority of children, which was 43.8%.

Conclusion: The common causes of neonatal cholestasis in this study are galactosemia, idiopathic hepatitis, and biliary atresia. The common presentation includes jaundice, hepatomegaly, direct hyperbilirubinemia, raised liver enzymes, and INR.

Course of vitamin D levels before and after liver transplantation in pediatric patients

BACKGROUND

25-hydroxy VD insufficiency is known in children undergoing LT but the serial post-transplant VD course and supplementation modalities in the peri-transplant period are lacking. We aimed to determine the pre-VD status and the post-transplant VD status course following VD supplementation and to elucidate its relationship with post-transplant outcome parameters such as infection and survival.

METHODS

Pre- and post-VD levels were monitored in parallel with interventions to adjust VD levels in LT patients. VD status was categorized as circulating levels <30-21 ng/ml (insufficiency), 20-10 ng/ml (deficiency), and <10 ng/ml (severe deficiency). Patients received stoss (300000IU) VD3 within the pretransplant period if serum levels were <20 ng/ml.

RESULTS

135 transplanted children were included. The age at LT was 22 months (IQR: 8-60). The pretransplant median VD level was 14 ng/ml. Despite stoss dose, post-transplant median VD level was 1.8 ng/ml (day one), 4 ng/ml (week one), 19 ng/ml (month one), 33 ng/ml (month three), 38 ng/ml (months 6-12), and 40 ng/ml (month 24). After 6 months, VD status reached >30 ng/ml in 98% of patients. Only at pre-LT, higher infection rate (18.7%) in the severe VD deficiency group was observed compared to the VD deficiency group (2.9%, p = .04). Survival was not affected by serum VD levels.

CONCLUSION

VD levels fell substantially after LT but are rectifiable by stoss dose, which was well tolerated. Only the infection rate was associated with the VD status.

Variant etiologies of neonatal cholestasis and their outcome: a Middle East single-center experience

AIM OF THE STUDY

Neonatal cholestasis (NC) constitutes a large proportion of pediatric liver disorders. Nevertheless, awareness of the variant etiologies and how to manage them appropriately are lacking. So, out of a few specialized centers, many cases pass without appropriate management. This study aimed to present our tertiary level center's experience in NC that could increase the pediatrician's awareness of handling this problematic and common medical morbidity efficiently.

MATERIAL AND METHODS

It is a retrospective study in which we analyzed the NC cases admitted to the inpatient department within three years. For all recruited patients, the available data were retrieved and recorded.

RESULTS

A total of 412 patients were reviewed with 20 different etiologies diagnosed. The most common cause was biliary atresia (n = 151, 37%), followed by progressive familial intrahepatic cholestasis (n = 51, 12%), neonatal sepsis (n = 39, 9%), and cytomegalovirus (n = 33, 8%). Of the 412 patients, 394 (81%) had follow-up ranging from 1 to 36 months. A total of 173 patients improved with supportive and/or specific therapy, while 108 patients died at a median age of 6 months. The commonest cause of death was liver failure (40.7%), followed by pneumonia (28.7%), sudden death (13%), septicemia (6.5%), and hepatorenal syndrome (5.5%).

CONCLUSIONS

NC constitutes more than one-third of the inpatient admissions of all pediatric liver disorders and has a high rate of mortality. Awareness of the variety of etiologies and a rapid stepwise approach to diagnosis could have an impact on the outcome of this devastating disease.

Hepatic interferon γ and tumor necrosis factor a expression in infants with neonatal cholestasis and cytomegalovirus infection

Aim of the study

To determine the hepatic interferon γ (IFN-γ) and tumor necrosis factor α (TNF-α) levels in infants with neonatal cholestasis (NC) and associated cytomegalovirus (CMV) infection.

Material and methods

This study was conducted in 21 infants with NC over a period of 6 months from June 2017 to December 2017 to determine the hepatic IFN-γ and TNF-α levels in infants with NC and associated CMV infection.

Results

IFN-γ levels were positive in 16 (80%), low positive in 3 (16%) and negative in 1 (5%) patients. High positive and positive TNF-α levels were seen in 9 (56.3%) patients with positive liver CMV PCR and low positive levels were seen in 7 (43.7%) patients with positive liver CMV PCR (odds ratio [OR] = 2.6). Positive IFN-γ was present in 13 (81.3%) patients with positive liver CMV PCR and low positive or negative IFN-γ was seen in 3 (18.7%) patients with positive liver CMV PCR (OR = 2.2). Six (60%) patients with positive or high positive TNF-α levels in liver tissue had biliary atresia (BA) whereas 7 (77.7%) with low positive TNF-α levels had non-BA neonatal hepatitis (OR = 5.25). Six (37.5%) patients with positive IFN-γ had BA whereas 2 (50%) patients with low positive or negative IFN-γ had BA (OR = 0.6).

Conclusions

There is high prevalence of CMV in liver tissues in patients with NC and elevated TNF-α and IFN-γ levels are seen in these patients. Elevated TNF-α is also seen in patients with BA. The association of elevated TNF-α, BA and CMV infection needs to be evaluated further.

Development of integrated neonatal cholestasis card for early recognition and referral of neonatal cholestasis

INTRODUCTION AND AIM

Delayed referral of neonatal cholestasis (NC) can result in significant morbidity and mortality. In this multi-center study, we aimed to evaluate the reliability of the stool card in the Indian population and develop an integrated NC card with (a) urine color identification and (b) stool color for early referral.

METHODS

Consecutive children with NC were enrolled and divided into two groups (biliary atresia [BA] and non-BA). Normal healthy children at 6-8 weeks of age served as controls. Each photograph of stool and urine samples of every child was evaluated by 6 parents, 6 paramedical staff, and 4 trainee doctors using a stool color card as a reference for stool samples.

RESULTS

Of 319 children (BA [n = 58], non-BA [n = 62], and controls [n = 199]), parents correctly detected dark yellow urine in all NC. Stool samples of 50 (86%) children with BA were unanimously labeled as pale by all observers. The average inter-item correlation showed good correlation between parents and trainee doctors of 0.77 and 0.64 with paramedical staff.

CONCLUSION

The integrated NC card proposes to recognize neonatal cholestasis at an early stage irrespective of etiology. It is a major step towards public health benefit both at the community as well as physicians' levels to enable early detection and timely referral and management.

Non Syndromic Paucity of Interlobular Bile Ducts in Children - A Clinicopathological Study

Background: Non syndromic paucity of interlobular bile ducts (NS-PILBD) constitutes a miniscule of infantile cholestasis. Method: Clinical details, investigations, surgical findings, management and outcome of cases of NS-PILBD at liver biopsy were analyzed. Specific histopathological features including bile duct to portal tract ratio were studied. Results: Eighteen cases (1993-2013) are detailed. Clinical presentation and investigations were similar to biliary atresia. Hepatic scintigraphy showed no gut excretion in 13/18 and operative cholangiogram was normal in all. Liver biopsy showed a median Scheuer fibrosis stage of 2, the mean bile duct/portal tract ratio was 0.29. The average age at last follow up of twelve cases was 54.9 months . Ten were asymptomatic and anicteric, the liver function tests had normalized over 3-15 months. Conclusion: Histopathology differentiated NS-PILBD from other causes of infantile cholestasis .The idiopathic form generally had a favorable long term outcome with medical management.

Neonatal Jaundice

Hyperbilirubinemia is a common occurrence in neonates; it may be physiological or pathological. Conjugated hyperbilirubinemia may result from medical or surgical causes, and can result in irreversible liver damage if untreated. The aim of imaging is the timely diagnosis of surgical conditions like biliary atresia and choledochal cysts. Abdominal ultrasound is the first line imaging modality, and Magnetic resonance cholangiopancreatography (MRCP) also has a role, especially in pre-operative assessment of choledochal cysts (CDCs). For biliary atresia, the triangular cord sign and gallbladder abnormalities are the two most useful ultrasound features, with a combined sensitivity of 95%. Liver biopsy has an important role in pre-operative evaluation; however, the gold standard for diagnosis of biliary atresia remains an intra-operative cholangiogram. Choledochal cysts are classified into types according to the number, location, extent and morphology of the areas of cystic dilatation. They are often associated with an abnormal pancreaticobiliary junction, which is best assessed on MRCP. Caroli's disease or type 5 CDC comprises of multiple intrahepatic cysts. CDCs, though benign, require surgery as they may be associated with complications like cholelithiasis, cholangitis and development of malignancy. Severe unconjugated hyperbilirubinemia puts neonates at high risk of developing bilirubin induced brain injury, which may be acute or chronic. Magnetic resonance imaging of the brain is the preferred modality for evaluation, and shows characteristic involvement of the globus pallidi, subthalamic nuclei and cerebellum - in acute cases, these areas show T1 hyperintensity, while chronic cases typically show hyperintensity on T2 weighted images.

Reductive effect of ursodeoxycholic acid on bilirubin levels in neonates on phototherapy

Background

Phototherapy is paramount in the management of high total serum bilirubin (TSB). Whether its effectiveness can be improved with ursodeoxycholic acid (UDCA) has not been evaluated among newborns of African descent.

Methods

A double-blind-controlled study was used to evaluate the effect of UDCA on the management of high TSB in neonates. Recruited neonates were categorized into the experimental group (given UDCA plus phototherapy) and the control group (phototherapy and plain syrup), and their TSB and conjugated bilirubin levels were measured. The data were analyzed using SPSS version 20. Statistical significance was set at a p-value of <0.05.

Results

The mean (SD) percentage reductions in TSB after 24 hrs were 40.73% (18.1) and 10.21% (7.1) in the experimental and control groups, respectively, and the difference was statistically significant (p=0.001). The mean (SD) durations on therapy were 3.0 days (0.58) in the experimental group and 5.5 days (1.35) in the control group (p=0.001).

Conclusions

Phototherapy is still effective in the management of neonatal hyperbilirubinemia, but inclusion of UDCA accentuates the reductive effect of phototherapy on the TSB in neonates, reducing the duration of treatment and in-patient care.

A systematic review of standard treatment guidelines in India

Background & objectives

Standard treatment guidelines (STGs) are the cornerstone to therapeutics. Multiple agencies in India develop STGs. This systematic review was conducted to find out STGs available in India, evaluate if these were as per World Health Organization (WHO) recommendations for STGs and compare these with National Institute for Health and Care Excellence (NICE) guidelines. Information on legal authority and responsibility for formulating STGs was also sought.

Methods

PRISMA guidelines were followed. Publications from PubMed and Google Scholar were searched for STGs using terms 'Standard Treatment Guidelines AND India'. Data from STGs were compiled in excel as per the WHO and authors' criteria for STGs and compared with NICE guidelines.

Results

PubMed and Google Scholar search provided 56 publications (out of 1695 search results) mentioning 27 STGs. Google search and replies from authors led us 36 STGs, totalling to 63 STGs. No STG mentioned any specific period of revision, eight STGs were not evidence-based, 55 had some Indian references, 48 STGs were for single disease and the remaining multi-disease, three STGs did not include diagnostic criteria, 16 STGs did not give prescribing information of recommended treatment and 16 STGs provide no referral criteria for patients. Fifty five STGs did not mention level of health care. While NICE is a single legal authority in England and guidelines are as per WHO recommendations for STGs, in India although Acts and rules do not vest authority, National Health Systems Resource Center is generally designated responsible for STGs.

Interpretation & conclusions

In India, although there are multiple STGs developed by various authorities and professionals for the same conditions, these fulfil WHO recommendations only partially. Authority with statutory duty collaborating with professional organizations, a standard methodology for adopting international guidelines, Indian data for evidence base, attention to local needs will help in developing better STGs and their acceptance.

Design and validation of a noninvasive diagnostic criteria for biliary atresia in infants based on the STROBE compliant

It is difficult for clinicians to distinguish biliary atresia (BA) from other causes of neonatal cholestasis (NC) at an early stage. The aim of this study was to design and validate noninvasive diagnostic criterion for early diagnosis of BA in infants.In this retrospective cohort study, a total of 482 medical records of patients with NC were recruited to design diagnostic criteria. Parameters showing a significant difference between BA (n = 166) and non-BA (n = 316) patients were analyzed by logistic regression to predict the occurrence of BA, and then a nomogram scoring system was designed and validated in another cohort that included 190 cases of NC.A prediction diagnostic criterion with parameters including direct bilirubin, total bilirubin, globulin, albumin, gamma glutamyl transpeptidase, cholesterol, total bile acid, hepatobiliary scintigraphy, birth weight, and stool color was established; the sensitivity and specificity of this diagnostic criterion was 89% and 84%, respectively. The accuracy was 86% and the AUC was 0.91 [95% CI (0.88-0.97)]. The total score ranged from 0 to 402, with a cut-off value of ≥254 discriminating BA from other causes of NC. By applying this score in the validation set with age <60 days, the accuracy was 95.3%, the sensitivity was 93.8% and the specificity was 96.0%, respectively.This prediction diagnostic criterion could facilitate clinicians to distinguish infants with and without BA based on a particular series of parameters, reducing treatment burden and enhancing therapeutic efficiency.

Need for recognizing atypical manifestations of childhood sporadic acute viral hepatitis warranting differences in management

Various atypical manifestations have been described in acute viral hepatitis (AVH). We evaluated the prevalence, clinical features, response to treatment and outcome of various atypical manifestations of AVH in children. Consecutive children (≤ 18 years) with AVH due to hepatitis A, B, or E were studied while patients with acute or acute on chronic liver failure were excluded. Diagnosis of atypical manifestations was based on standard criteria. A total of 477 children with AVH (median age 7.0 (5-11) years, 74% boys) were seen; 22% (n = 106) had atypical manifestations. Prolonged cholestasis was the most common (11%), followed by ascites (7%), intravascular hemolysis (3%), relapsing hepatitis (2%), acute pancreatitis (1.3%), and thrombocytopenia (0.7%). Atypical manifestations were more common in HAV as compared to HBV (30% vs. 3%, p = 0.00) and HEV (30% vs. 15%, p = 0.07). Prolonged cholestasis was significantly more common in older children (20% in > 10 years vs. 9% in 6-10 years ; p = 0.009 and 5% in 0-5 years of age [p < 0.000]). Ascites was more common in younger children, although not significant. All patients recovered with supportive treatment.Conclusions: Twenty-two percent of children with AVH have atypical manifestations, more often with HAV infection, and prolonged cholestasis is most common. Recognition of these manifestations ensures correct diagnosis and treatment. What is Known: • Acute viral hepatitis is a major public health problem in developing countries. • There is limited information about atypical manifestations which may lead to unnecessary investigations, delayed diagnosis and morbidity. What is New: • Atypical manifestations are common in children, seen most often with HAV infection, and prolonged cholestasis is most common. • Prompt recognition of these manifestations helps in early diagnosis, appropriate management, and preventing unnecessary investigations. • Ensure follow-up until complete recovery and not to miss underlying chronic liver disease.

Detection of Cytomegalovirus in Liver Tissue by Polymerase Chain Reaction in Infants With Neonatal Cholestasis

AIM

Cytomegalovirus (CMV) is associated with neonatal cholestasis (NC). Diagnosis of CMV infection is most often based on either positive blood CMV IgM or CMV blood polymerase chain reaction (PCR). Isolation of CMV in liver tissues in patients with NC has rarely been reported. This study was undertaken to see if CMV is present in liver tissues of patients with NC and evaluate the correlation between positive CMV PCR in liver tissue with the serology and blood PCR.

METHODS

This study was conducted in 31 infants with NC from June 2015 to December 2016. All patients underwent blood CMV IgM, blood CMV PCR and liver CMV PCR. Prevalence of CMV in NC based on positive liver CMV PCR was calculated. Sensitivity and specificity of the serologic markers and blood CMV PCR to identify CMV infection in the liver was determined.

RESULTS

CMV IgM was positive in 13 (42%) patients, CMV IgG was positive in 26 (84%) patients and blood CMV PCR was positive in 23 (74%) patients. Liver CMV PCR was positive in 16 (52%) patients. Fifteen (48%) patients had biliary atresia (BA), 10 (32%) patients had neonatal hepatitis, 5 (16%) had paucity of bile ducts and 1 (3%) had ascending cholangitis. Of the 16 patients with positive liver CMV PCR, 8 (50%) had BA, 4 (25%) had neonatal hepatitis, 3 (19%) had paucity of bile ducts and 1 (6%) had ascending cholangitis. Sensitivity of blood CMV IgM in relation to liver CMV PCR was 69% and specificity was 61%. Sensitivity of blood CMV PCR was 61% and specificity was 71% when compared with liver CMV PCR.

CONCLUSION

CMV is present in the liver tissues of more than half the patients with NC. Serology or blood CMV PCR is apparently not an accurate marker of CMV in the liver tissue. Also, CMV infection in children seems to be associated equally with BA or non-BA neonatal hepatitis.

Referral Patterns and Factors Influencing Age at Admission of Infants with Cholestasis in India

OBJECTIVES

To define the recognition, age at admission, referral time and referral pattern of neonatal cholestasis in India.

METHODS

This prospective, observational study was conducted from February 2015 through March 2016 in the Pediatric gastroenterology unit of JIPMER, Pondicherry in infants with cholestasis < 6 mo of age.

RESULTS

Among 64 infants, median age of admission was 52 d (IQR 28-63 d). Fifty of sixty four infants (78.1%) came with parent-reported cholestasis-related symptoms of either jaundice alone (57.8%) or bleeding manifestations (20.3%). In 21.9% infants, jaundice was detected by physicians at a median age of 45 d (IQR 38.5-53.2 d). Two infants had intracranial bleed. Only 34% infants with pale stools were identified by the mother. The median healthcare-seeking time was 5.5 d (IQR 2.5-12 d). Among infants presenting to primary healthcare physicians (PHPs) with cholestasis-related symptoms, median time to referral was 5 d (IQR 2.5-12 d). The first point of healthcare contact in 54.7% was a PHP; 17.1% PHPs had reassured the parents. Herbal preparations were prescribed by 14.3%. Only 11.8% of those with jaundice as the only problem were given vitamin K before referral. Biliary atresia (BA) was missed in neonatal intensive care units in 9 cases.

CONCLUSIONS

The above issues need to be accounted for before evaluating or implementing screening strategies in India.

A 10-year-old child presenting with syndromic paucity of bile ducts (Alagille syndrome): a case report

Background

Alagille syndrome, a rare genetic disorder with autosomal dominant transmission, manifests with five major features: paucity of interlobular bile ducts, characteristic facies, posterior embryotoxon, vertebral defects, and peripheral pulmonary stenosis. Globally, only 500 cases have so far been reported, with only five cases reported in the Indian subcontinent. Rarely, Alagille syndrome also presents with skin manifestations and early-onset chronic liver disease, which was found in our case. We believe that we report what could be the first case of Alagille syndrome presenting with café au lait spots, as no such published case report could be found in the literature.

Case presentation

We report an unusual case of childhood cholestatic jaundice with neonatal onset of jaundice. A 10-year-old boy from the Indian subcontinent presented with obstructive jaundice from early infancy. He also had recurrent fractures of his upper limb bones, intermittent bleeding from his nose, productive cough, decreased night vision, hyperpigmented spots over his skin, and progressive enlargement of his abdomen. Histological examination of a liver biopsy specimen revealed a paucity of bile ducts and changes suggestive of chronic liver disease. Our patient was diagnosed with Alagille syndrome and managed conservatively but died 1 year after the final diagnosis.

Conclusions

This particular syndromic form of paucity of bile duct disorder has been rarely reported in the Indian literature so far. Our case is notable because the child had café au lait spots and very early onset of chronic liver disease, which is quite rare in Alagille syndrome. We believe this to be the first case report on Alagille syndrome manifesting with café au lait syndrome and such early onset of chronic liver disease.
