How to suspect the presence of high-risk esophageal varices and when to start endoscopic surveillance in children with biliary atresia?

BACKGROUND AND AIM: Portal hypertension determines the outcome of children with biliary atresia (BA) and is common even after a successful Kasai portoenterostomy (KPE). However, there are no clear-cut guidelines on the age of starting surveillance and the modality (endoscopy vs non-invasive tests [NITs]). In this cohort study, we analyzed our database to find out the utility of NITs in detecting high-risk esophageal varices in BA. METHODS: From June 2010 to May 2022, consecutive children of BA who underwent upper gastrointestinal (UGI) endoscopy were included. Esophageal varices were classified as high-risk (grade II with red-color signs or grade III or IV irrespective of red-color signs. NITs such as splenomegaly (clinical and USG), platelet count, aspartate transaminase to platelet ratio index (APRI), and platelet-to-spleen diameter ratio were compared between cases with high-risk and low-risk varices. RESULTS: A total of 110 children, 75 boys (66 successful KPE and 44 failed/KPE not performed) were enrolled. The median age at KPE was 85 days (IQR 63-98). Thirteen (11.8%) children presented with UGI bleeding. The first endoscopy revealed gastroesophageal varices in 75.4% of cases, and 32% of them had high-risk varices. Multivariate analysis revealed failed KPE, history of UGI bleeding, bigger spleen size (> 3.5 cm), lower platelet count (< 150 000), and higher APRI (> 2) are independent predictors of the presence of high-risk esophageal varices. CONCLUSION: Endoscopy is the best in predicting the presence of high-risk varices that might bleed; hence, early surveillance endoscopy should be started in children with splenomegaly, thrombocytopenia, and high APRI score to prevent variceal bleeding.

Efficacy and Predictors of Pain Response to Combined Antioxidants in Children with Chronic Pancreatitis.

BACKGROUND: Pain is a major problem in 90% of patients with chronic pancreatitis (CP). Studies evaluating response to antioxidants (AO) are conflicting and no pediatric studies are available. AIMS: To evaluate markers of oxidative stress (OS), and efficacy and predictors of response to AO in improving pain in children with CP. METHODS: Antioxidants were given to CP children for 6 months. Subjects were assessed at baseline and post-therapy for pain and markers of OS [serum thiobarbituric acid reactive substances (TBARS), superoxide dismutase (S-SOD)] and antioxidant levels [vitamin C, selenium, total antioxidant capacity-ferric reducing ability of plasma (FRAP)]. Matched healthy controls were assessed for OS and antioxidant levels. Good response was defined as ≥ 50% reduction in number of painful days/month. RESULTS: 48 CP children (25 boys, age 13 years) and 14 controls were enrolled. 38/48 cases completed 6 months of therapy. CP cases had higher OS [TBARS (7.8 vs 5.2 nmol/mL; p < 0.001)] and lower antioxidant levels [FRAP (231 vs. 381.3 µmol/L; p = 0.003), vitamin C (0.646 vs. 0.780 mg/dL; p < 0.001)] than controls. Significant reduction in TBARS and S-SOD and increase in FRAP, vitamin C, and selenium occurred after 6 months. 10.5% cases had minor side effects. 26(68%) cases had a good response, with 9(24%) becoming pain-free. Subjects with severe ductal changes had lower median BMI (- 0.73 vs 0.10; p = 0.04) and responded less often than those with mild changes (17/29 vs 9/9; p = 0.036). CONCLUSION: CP children have higher OS than healthy controls. Antioxidant therapy is safe. Pain response is seen in 68% cases, less often in patients with severe ductal changes.

Relative Adrenal Insufficiency in Decompensated Cirrhotic Children: Does It Affect Outcome?

INTRODUCTION: Relative adrenal insufficiency (RAI) is associated with poor outcome in adult cirrhotics. So far, pediatric studies are not available on the same. We aimed to prospectively study the presence and outcome of RAI in children with decompensated cirrhosis over 180 days. METHODS: Hemodynamically stable children with decompensated cirrhosis were sampled for serum basal cortisol and peak cortisol (after 30 minutes of 1-µg intravenous Synacthen) at day 1 and day 21. RAI was diagnosed as peak cortisol <500 nmol/L. Serum cytokines (interleukin-6 and tumor necrosis factor-α) and lipid profile were correlated with RAI. Cohort was followed up for outcomes over 180 days for complications and survival. With the identified risk factors, prognostic models were derived and compared with pediatric end-stage liver disease (PELD) and Child-Turcotte-Pugh scores. RESULTS: Prevalence of RAI was 54% at baseline and 61% at day 21 in the enrolled patients (n = 63, aged 128 ± 48 months, male 78%). No significant differences in cytokines and serum lipid levels were seen between RAI and normal adrenal function groups. Patients with RAI at baseline (D1-RAI) developed higher complications at follow-up as compared to the normal adrenal function group (53% vs 24%, P = 0.02). The PELD score (odds ratio 1.08, confidence interval 1.05-1.12, P < 0.01) and D1-RAI (odds ratio 3.19, confidence interval 1.32-7.73, P = 0.01) were independent predictors of follow-up complications. The PELD-delta cortisol model (area under the receiver operating curve 0.84, P < 0.001, 92% sensitivity; 60% specificity) predicted morbidity better than isolated PELD or Child-Turcotte-Pugh scores. DISCUSSION: RAI is a risk factor for development of complications in pediatric cirrhosis over short-term follow-up. The PELD-delta cortisol score is a promising prognostic model for predicting follow-up complications.

Efficacy of amitriptyline in pediatric functional abdominal pain disorders: A randomized placebo-controlled trial.

BACKGROUND AND AIM: Amitriptyline improves symptoms in functional abdominal pain disorders (FAPD) in adults with variable results in pediatric studies. The study aims to evaluate the efficacy of amitriptyline in pediatric FAPD. METHODS: In this open-label trial, children (≤ 18 years) diagnosed as FAPD based on ROME IV criteria were randomized to amitriptyline or placebo for 12 weeks. Post-treatment improvement of pain and quality of life (QOL) from the baseline were compared between the two groups. RESULTS: The mean age of 149 children (amitriptyline 75, placebo 74) was 11.3 ± 3.5 years (79 boys). There was a significant difference in pain improvement in terms of reduction in scores for intensity (3.4 vs 0.9), frequency (3.6 vs 0.6), duration (3.5 vs 0.9), and QOL (2.3 vs 0.9) between amitriptyline and placebo group (P < 0.001 in all). Responders (> 50% reduction) in pain was seen in 76% in amitriptyline compared with 14.9% in the placebo group (P < 0.001). On multivariate analysis, the use of amitriptyline was the only factor predictive of response (odds ratio 24.1, 95% confidence interval: 9.1-64.6, P < 0.001). Minor adverse events were comparable between the groups (25.3% vs 13.5%, respectively, P = 0.07). Eighty-nine percent of children (24/27) who had extended treatment duration (6.8 ± 1.8 months) had pain improvement. After discontinuation of amitriptyline, 70% had sustained response over a mean follow up of 15.84 ± 5.6 months. CONCLUSIONS: A 3-month trial of amitriptyline gives sustained relief of pain in two-thirds of children with FAPD. The safety profile of the drug and its efficacy necessitate more frequent use in the clinical settings.

Gastrointestinal bleeding due to pseudoaneurysms in children.

Radiological embolization is the treatment of choice in adults with visceral artery pseudoaneurysm (PSA) and gastrointestinal bleeding, but pediatric data is scanty. We analyzed the etiology, clinical presentation, and outcome of radiological intervention in children with PSA of celiac (CA) or superior mesenteric artery (SMA) branches. Electronic records of children with PSA of CA or SMA branches were reviewed and data on clinical and laboratory profile, radiological intervention, and outcome was recorded. Eleven children with PSA (5 boys, 11 [7-17] years) were studied. Etiology was liver abscess (n 4), abdominal trauma (n 3), pancreatitis (n 3), and indeterminate in 1 case. Ten (91%) patients were symptomatic: abdominal pain (10, 91%), hematemesis/melena (9, 81%), and Quincke's triad (1, 9%). One child with pancreatic pseudocyst was diagnosed incidentally on imaging. Doppler ultrasound identified PSA only in 3 cases, while computed tomography angiography (CTA) picked all cases. Children with liver abscess, trauma, and unknown etiology had PSA from CA (right hepatic artery 7, left hepatic artery 1). Of the 3 pancreatitis cases, 2 had PSA from SMA (inferior pancreatico-duodenal artery and ileal branch) and 1 from CA (left gastric artery). Radiological embolization was done in 9 (81%) cases (coil 6, glue 2, both 1), without any complications or failure. One case resolved spontaneously and 1 died pre-intervention. Nine intervened cases were asymptomatic in follow-up [6 (1-24) months].Conclusion: Liver abscess, trauma, and pancreatitis are causes of PSA of CA and SMA branches in children. A majority present with gastrointestinal bleeding and are identified on CTA. Radiological embolization was safe with 100% success. What is Known: • Pseudoaneurysm of visceral artery is an uncommon cause of gastrointestinal bleeding. • Endoluminal intervention is an established and efficacious treatment modality in adults and preferred over surgery. What is New: • Liver abscess, abdominal trauma and pancreatitis are common causes of celiac artery and superior mesenteric artery branch pseudoaneurysm in children and computed tomography angiography has high sensitivity in identifying these pseudoaneurysms. • Minimally invasive radiological angio-embolization, in the hands of trained radiologists, is a safe and successful modality of treatment in children.

Endoscopic cystogastrostomy: Still a viable option in children with symptomatic pancreatic fluid collection.

BACKGROUND/OBJECTIVES: Endoscopic transmural drainage is the preferred method of drainage of pancreatic fluid collections (PFCs) in adults; however, there is scant literature in children. We analyzed our experience of 33 endoscopic cystogastrostomies done in 29 children to find its efficacy and safety. METHODS: We retrospectively analyzed the prospectively collected database of 31 consecutive children (<18 years) who underwent endoscopic cystogastrostomy from June 2013 to December 2017. The procedure was done using the standard technique with an adult duodenoscope. Data related to clinical details, technical success, complications and follow-up were collected. RESULTS: The median age was 14 (3-17) years (22 males). Indications were early satiety in 28 (90%), vomiting in 15 (48%), and duodenal obstruction and infected pseudocyst in 2 children each. Etiology includes acute pancreatitis 22, post-traumatic 4 and chronic pancreatitis 5. The procedure was successful in 29 of 31 (93.5%) children with no mortality. Adverse events happened in four cases (12.9%); two infections, another with bleeding and another with pneumoperitonium, both of which resolved spontaneously. Incidents (minor bleeding) were noted in 6 (19%). Stents were removed in 26 (90%) after 12 (7-20) weeks and got spontaneously migrated out in 3 (10%) cases. Over a median follow-up of 26 (5-48) months, 26 (90%) had no recurrence of pseudocyst and 3 (10%) had recurrence of a small, asymptomatic pseudocyst. CONCLUSIONS: Endoscopic cystogastrostomy is a safe and effective method of draining bulging PFCs in children. The procedure carries acceptable morbidity with minimal recurrence. In younger children it may be the preferred method of drainage of PFCs.

Gastrointestinal Polyps and Polyposis in Children: Experience of Endoscopic and Surgical Outcomes.

INTRODUCTION: There are gaps in the literature regarding outcome of multiple polyps and dilemmas in the management issues in polyposis syndromes in children. OBJECTIVE: We aimed to study the clinical behaviour of gastrointestinal (GI) polyps with emphasis on therapeutic outcomes of polyposis syndrome. METHODS: Proven cases of GI polyp(s) on endoscopy were classified as single polyp, multiple polyps, and polyposis syndrome. Complex presentation was defined as 1 or more of the following: severe anaemia, anasarca, intussusception, rectal mucosal prolapse, and diarrhoea. A clinico-endoscopic criterion was applied in polyposis syndrome patients for the decision of surgery versus endoscopic therapy with surveillance. RESULTS: Of total 240 patients, there were no significant differences between single (52.5%, n = 126) versus multiple polyps (27.5%, n = 66) with respect to age, symptoms, histology, and recurrence. Polyposis syndrome (20%, n = 48) presented with complex symptoms (50%), higher family history, significantly lower haemoglobin, total protein, and albumin as compared to single and multiple polyps (p < 0.01). Nineteen polyposis patients with favourable clinico-endoscopic criteria were endoscopically eradicated for polyps in 3 (1-4) sessions with sustenance of laboratory parameters at 1 year and 30% symptomatic recurrence at follow-up of 23.5 (7-40) months. There were no major endoscopic complications. Nineteen patients required proctocolectomy with improvement in laboratory parameters 6 months post-surgery. CONCLUSIONS: Multiple polyps behave similar to single polyps in children. A clinico-endoscopic criterion may guide for optimal management of polyposis syndrome. Colectomy may be effectively deferred in a large proportion of polyposis syndrome patients if maintained on an endoscopic protocol.

Functional dyspepsia in children: A study of pathophysiological factors.

BACKGROUND AND AIM: Functional dyspepsia (FD) is common in children, and treatment targeted towards the altered pathophysiology can improve outcome. We evaluated FD children for abnormality of gastric accommodation and emptying, psychological stressors (PS), Helicobacter pylori (HP) infection, and post-infectious FD. METHODS: Diagnosis of FD was based on ROME III criteria. Clinical evaluation including dyspeptic symptom scoring and assessment for PS was performed. Satiety drink test for gastric accommodation, gastroscopy with biopsy for HP infection, and solid meal gastric emptying were performed. Sixty-seven healthy children were enrolled for assessing PS and satiety drink test. RESULTS: Fifty-five FD children (33 boys, age 12 [6-18] years) with symptoms for 4 (2-48) months and dyspeptic score of 5 (1-13) were enrolled. PS were more common in FD than in controls (46/55 vs 9/67; P < 0.001). Median satiety drink volume was 360 mL (180-1320 mL); no patients had satiety drink volume of < 5th centile of healthy children. The frequency (98% vs 85%; P = 0.01) and severity (65 [10-175] vs 50 [5-130]; P < 0.001) of postprandial symptoms were higher in FD than in controls. Of the postprandial symptoms, pain (20.3% vs 0%; P = 0.000) was present only in FD. Delayed gastric emptying was present in 6.5%, HP infection in 11%, and post-infectious FD in 13% cases. Etiological factor was identified in 87% children, with 20% having multiple factors. CONCLUSIONS: Abnormality of gastric sensorimotor function is seen in one-fourth of FD cases. HP infection and post-infectious FD are present in 11% and 13% cases, respectively.

Childhood pancreatic trauma: Clinical presentation, natural history and outcome.

OBJECTIVES: To study the presentation, management strategies and long-term natural history of children with pancreatic trauma. METHODS: Children admitted with pancreatic trauma were analyzed for their presentation, management and outcome. Management included nasojejunal feeds, total parenteral nutrition (TPN), octreotide, drainage (radiological and endoscopic), endoscopic retrograde cholangiopancreatography (ERCP) and surgery. Patients were assessed in follow-up for development of chronic pancreatitis (CP). RESULTS: 36 children [29 boys, age 144 (13-194) months] presented at 30 (3-210) days after trauma. Most common cause of trauma was bicycle handle bar injury [n = 18,50%]. Presenting features were abdominal pain [n = 26,72%], lump [n = 16, 44.4%], ascites [n = 13,36%], pleural effusion [n = 9,25%] and anasarca [n = 3,8.3%]. All presented with sequelae of ductal disruption with pseudocyst, ascites or pleural effusion. Fifteen (41.6%) patients each had Grade III and IV injury, 4 (11%) had grade V, and grading was unavailable in 2. Other organs were injured in 4 (11%) cases. Management consisted of various combinations of nasojejunal feeds [n = 17,47.2%], TPN [n = 5,13.8%], octreotide [n = 13,36%], pseudocyst drainage [radiological (n = 18,50%), endoscopic (n = 3,8.3%)] and ERCP [n = 12,33.3%]. Surgical intervention was done in 2 (5.5%) cases [cystojejunostomy and peritoneal lavage in 1 each]. Two (5.5%) patients died due to sepsis. Of the 32 cases in follow-up, 19 (59.3%) recovered and 13 (40.6%) developed CP, with half (6/13) of them being symptomatic with recurrent pain. CONCLUSION: Multi-disciplinary non-operative management is effective for managing pancreatic trauma in 94.4% of children, with 75% requiring radiological or endoscopic intervention. 40% developed structural changes later but only half were symptomatic.

Late-Onset Hepatic Failure in Children: Risk Factors that Determine the Outcome.

BACKGROUND: Late-onset hepatic failure (LOHF) is a distinct entity of intractable liver diseases with limited pediatric experience. We aimed to identify the etiology and risk factors that determine the poor outcome (PO) of pediatric LOHF. METHODS: LOHF was defined as liver failure occurring 5-24 weeks after onset of jaundice and without any evidence of underlying chronic liver disease. PO (death or liver transplantation within 160 days) was compared with spontaneous recovery (SR; complete normalization of liver functions in the native liver). Pediatric end-stage liver disease (PELD) score and King's College Criteria (KCC) were applied to investigate their prognostic value. RESULTS: We enrolled 47 children (6 [2-16] years) with LOHF. Hepatitis A was the most common etiology (15, 32%) and 64% complicated with infections. Twelve children (25%) had SR over 6 (1-24) months, while 28 (60%) children had PO. Univariate analysis showed indeterminate etiology, hepatic encephalopathy (HE), infection, acute kidney injury, and high PELD score determined PO. On multivariate regression analysis, only PELD score with a cutoff 32 (area under curve 0.833, sensitivity 68%, specificity 92%) predicted PO. KCC showed a sensitivity of 85.7%, specificity of 41.7% to determine PO in our cohort. CONCLUSION: Indeterminate etiology, presence of HE, occurrence of infection at any site, and acute kidney injury lead to the PO. PELD score ≥32 can be utilized to optimize the listing for liver transplantation. A significant proportion survives with the native liver.

Efficacy of Single- Versus Split-dose Polyethylene Glycol for Colonic Preparation in Children: A Randomized Control Study.

OBJECTIVES: Polyethylene glycol (PEG) is the most effective colon-cleansing agent but volume-related adverse effects are common. Though split-dose PEG is used in adults, no pediatric study so-far has compared split-dose with single-dose PEG. We aimed at comparing the efficacy and tolerability of split-dose versus single-dose PEG for bowel preparation in children. METHODS: Consecutive children (1-18 years) were randomized into either single-dose or split-dose PEG. Single-dose group received 4000 mL/1.73 m PEG solution day before colonoscopy whereas split-dose group received half dose day before and the remaining half on the day of colonoscopy. Effectiveness of bowel preparation was assessed on Aronchik scale, by the endoscopist who was blinded to the type of preparation. Interobserver variability was analyzed by comparing with independent scoring by the blinded trained endoscopy-nurse. The trial was registered with Clinical Trials Registry of India (Trail number 2017/08/009303). RESULTS: Of the 220 randomized children, 179 completed the study (split-dose: 93, single-dose: 86). The mean age of the study population was 11.51 (4.82) years (72.6% boys). The efficacy of bowel preparation was better with split-dose (satisfactory preparation:76.34% vs 43.02%, P < 0.001) with almost perfect inter-observer agreement (k = 0.803). Nausea, vomiting, and sleep disturbance were significantly less in split-dose than single-dose group (P < 0.05). Split-dose patients were able to drink PEG solution faster (P = 0.002). Total sleep duration and uninterrupted sleep duration was also better in split-dose group as compared with single-dose (P = 0.001). CONCLUSIONS: Split-dose PEG is more effective than single-dose regimen for bowel preparation with better tolerability and improved sleep quality in pediatric population.

Transjugular Versus Percutaneous Liver Biopsy in Children: Indication, Success, Yield, and Complications.

BACKGROUND/OBJECTIVE: Percutaneous biopsy (PB) and transjugular liver biopsy (TJLB) are 2 main ways of obtaining liver tissue. We evaluated the indications, success rate, tissue yield, and complications of TJLB in comparison to PB in children. METHODS: Electronic records of children undergoing liver biopsy (LB) were reviewed. Clinico laboratory data including indication, type of biopsy, complications, and tissue yield (length and number of complete portal tracts [CPT]) were noted. RESULTS: Five hundred forty LB (indication: neonatal cholestasis [42.9%], chronic liver disease [43.7%], liver failure [3.7%], focal lesions [3.3%] and others [6.3%]) were done. Four hundred seventy-three were PB (317 boys, 14 [1--216] months) done by percussion (322 [68%]), real-time ultrasound guidance (125 [26.4%]), or plugged method [26 (5.5%)]. Sixty-seven (12.4%) were TJLB [38 boys, 140 (24--216) months], done in patients with contraindications for PB. Technical success (67/68 vs 473/473; P = 0.7) and complications (4 [6%]; vs 15 [3.3%]; P = 0.2) of TJLB and PB were similar. Major complications (0.5%) included supraventricular tachycardia (n = 1) in TJLB and hemoperitoneum (n = 2) in PB. Tissue yield of TJLB was poorer in terms of length (1.0 [0.2--2.0] vs 1.1 [0.4--2.1] cm; P < 0.001), CPT (4 [0--9] vs 5 [2--17]; P < 0.001) and adequacy for reporting (56/67 vs 459/473; P < 0.001). Biopsy yield of <6 CPT was predicted by cirrhosis at histology and TJLB. No factor identified risk of complications with LB. CONCLUSIONS: LB is a safe procedure and only 12% children require TJLB because of contraindications of PB. Technical success and complications are similar but tissue yield is poorer in TJLB than PB. Presence of cirrhosis and TJLB adversely affected tissue yield.

Utility and accuracy of transient elastography in determining liver fibrosis: a case-control study.

The objectives of this prospective case-control study were to determine liver stiffness (LSM) by transient elastography (TE) in children with newly diagnosed chronic liver disease (CLD) and to find out normal values in healthy Indian children. Two groups (A: 50 CLD who underwent liver biopsy and B: 50 healthy) aged 5-18 years were recruited prospectively. Liver biopsies were scored as per Metavir scoring and compared with TE. The median age of 100 recruited children was 13.6 years. In group B, normal LSM was 4.9 (2.5-7.3) kPa with significantly higher LSM in adolescent males (5.6 (4.1-7.3) kPa) as compared with females (4.3 (3.7-4.9) kPa), p = 0.001. In group A, TE was excellent in discriminating significant fibrosis (≥ F2) (P = 0.001) at a cut-off value of 10.6 kPa with area under receiver operating characteristic curve of 0.96. Metavir fibrosis stage (ß = 0.611; R2 = 0.586) and age (ß = 0.230; R2 = 0.586) were independent variables associated with higher LSM in stepwise multiple logistic regression analysis.Conclusions: TE is an excellent non-invasive tool to assess significant liver fibrosis and can be used as an alternative to liver biopsy. Normative value of TE in adolescent males is higher than in females.What is Known:• Transient elastography is a good non-invasive test for liver fibrosis assessment.• Normal liver stiffness depends on race, gender, and age.What is New:• This is the first study from India to show the normative data of transient elastography in healthy Indian children.• We have documented that liver stiffness measurement by fibroscan in treatment naïve chronic liver disease has excellent correlation in significant fibrosis, severe fibrosis, and cirrhosis.

Clinical Profile, Response to Therapy, and Outcome of Children with Primary Intestinal Lymphangiectasia.

OBJECTIVE: Intestinal lymphangiectasia (IL; primary or secondary) is an important cause of protein-losing enteropathy. We evaluated the clinicolaboratory profile, response to therapy, complications, and outcome of children with primary IL (PIL). METHODS: Consecutive children (≤18 years) diagnosed with PIL (clinical setting, typical small bowel histopathology, and exclusion of secondary causes) from 2007 to 2017 were evaluated. RESULTS: Twenty-eight children with PIL (16 boys, age at symptom onset-12 [1-192] months and at diagnosis 8 [1-18] years) were studied. Pedal edema (93%), chronic diarrhea (78.6%), and recurrent anasarca (64%) were the common presentations. Ascites, pleural, and pericardial effusion were seen in 64 (n-18; chylous-5, non-chylous-13), 18, and 18% cases, respectively. Hypoproteinemia, hypoalbuminemia, hypocalcemia, and lymphopenia were present in 82, 82, 75 and 39% cases, respectively. Duodenal biopsy established the diagnosis in 86% cases, while 14% required distal small bowel biopsies. Dietary therapy was given in all and 6 cases required additional therapy (octreotide-6, tranexamic acid-3, and total parenteral nutrition-1). Lymphedema (3/5 vs. 1/23), pleural effusion (4/5 vs. 1/23), and the need for additional therapy (4/5 vs. 2/23) were significantly more in patients with chylous ascites (n = 5) than those without chylous ascites (n = 23). Twenty-four cases in follow-up (39 [6-120] months) showed improvement; however, 8 required readmission (symptom recurrence-6 [25%], complication-2 [8.3%], Budd Chiari Syndrome-1, and abdominal B cell lymphoma-1). CONCLUSION: Presence of chylous ascites suggests severe disease in children with PIL. Majority of PIL children respond to dietary therapy; only 20% need additional therapy. Long-term follow-up is essential to monitor for symptoms relapse and complications.

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.

Pediatric CLIF-SOFA score is the best predictor of 28-day mortality in children with decompensated chronic liver disease.

BACKGROUND & AIMS: Early identification of children with decompensated chronic liver disease (DCLD) at risk of short-term mortality helps improve outcome. We aimed to evaluate the predictors of outcome and role of Child-Pugh, pediatric end-stage liver disease (PELD) and pediatric chronic liver failure sequential organ failure assessment (pCLIF-SOFA) score for prognosticating 28-day mortality in children with DCLD. METHODS: DCLD children were prospectively evaluated with a clinico-laboratory proforma and followed for 28 days to determine outcome. Child-Pugh, PELD and pCLIF-SOFA were calculated at admission. Univariate and multivariate analysis was performed to identify the best predictors of outcome. RESULTS: A total of 110 children (74 boys, 96 [4-204] months) were enrolled and 37 (33.6%) died at 28 days. Significant risk factors for mortality were a higher international normalized ratio (hazard ratio [HR] 1.17; 95% CI 1.04-1.31; p <0.001) and bilirubin (HR 1.04; 95% CI 1.01-1.08; p <0.001), lower albumin (HR 0.46; 95% CI 0.27-0.77; p = 0.03) and sodium (HR 0.93; 95% CI 0.89-0.98; p = 0.01), absence of treatable etiology (HR 2.00; 95% CI 1.40-2.87; p = 0.001) and presence of organ failure (HR 3.22; 95% CI 1.98-10.58; p <0.001). Organ failure and serum sodium were independent predictors of poor outcome on multivariate analysis. pCLIF-SOFA (16 [9-22] vs. 9 [5-15]), Child-Pugh (11 [9-15] vs. 10 [8-14]) and PELD (22.2 [7.5-45.3] vs. 15.3 [4.5-23.9]) scores were significantly higher in non-survivors. The area under the curve was 0.977 for pCLIF-SOFA, 0.815 for Child-Pugh score, and 0.741 for PELD score. A pCLIF-SOFA score of ≥11 identified 28-day mortality with a sensitivity and specificity of 94.9% and 91.5%, respectively. CONCLUSION: Thirty-four percent of children with DCLD have a poor short-term outcome. Organ failure and low serum sodium are independent predictors of outcome. pCLIF-SOFA performs better than Child-Pugh and PELD in prognostication of 28-day mortality. Our study supports the use of scores based on organ failure in prognosticating children with DCLD. LAY SUMMARY: The ability to predict the course of a disease is an important part of the assessment, enabling timely interventions that improve outcomes. We evaluated the outcome (death vs. survival) and compared three different scoring systems for their ability to predict mortality within 28 days in children with decompensated chronic liver disease (DCLD). One-third of children with DCLD died within 28 days and the pediatric chronic liver failure sequential organ failure assessment score, which considers the main organ systems of the body (lungs, liver, brain, kidney, blood and cardiac) fared better for identification of children with a poor outcome than the Child-Pugh and pediatric end-stage liver disease score which comprise of only liver-related parameters. Our study supports the use of scores based on organ failure in prognosticating children with DCLD.

Children with untreated coeliac disease have sub-clinical cardiac dysfunction: a longitudinal observational analysis.

INTRODUCTION: We assessed cardiac function (CF) in celiac disease (CD) patients and the effect of gluten-free diet (GFD) on CF. METHODS: Prospective evaluation of CF using conventional and tissue doppler echocardiography in 50 CD patients (age 4.2 ± 1.1 years) at diagnosis and after a year of GFD (group 1), 100 CD children (group 2; 47 compliant and 53 non-compliant) in follow-up and 25 healthy controls. RESULTS: Untreated CD (n = 50) children had larger left ventricle end diastolic dimension (35.33 ± 0.87 vs. 32.90 ± 0.91 mm; p = .04), reduced (<55%) left ventricular ejection fraction (20% vs. 0%; p = .01) and a higher (>0.6) myocardial performance index (MPI, 66% vs. 0%; p ≤ .01) as compared to controls. Re-evaluation after one year with good dietary compliance showed changes in isovolumic relaxation time (72.5 ± 4.2 vs. 50.62 ± 2.69; p = .0001) and deceleration time (121.05 ± 10.1 vs. 99.87 ± 8.5; p = .02), reflecting improved cardiac diastolic function. GFD compliant patients had lower MPI than non-compliant (0.60 ± .03 vs. 0.66 ± .08; p = .04), reflecting improvement in load-independent echocardiographic parameters. CONCLUSIONS: Subclinical cardiac dysfunction is common in CD children at diagnosis. Improvement in echocardiographic parameters occurs with GFD and non-compliant children continue to have persistent cardiac dysfunction.

Intussusception in celiac disease: Is it a common feature in children?

BACKGROUND AND AIM: There are sporadic reports of occurrence of intussusception in celiac disease (CD) but no systematic study yet. We prospectively studied the prevalence and natural history of intussusception in newly diagnosed CD. METHODS: From January 2010 to October 2013, 150 children, diagnosed to have CD on the basis of positive serology and duodenal biopsy, were recruited in this study. Abdominal ultrasonography was carried out before starting gluten-free diet (GFD) and repeated in those who had intussusception, on day 3 and then weekly till the resolution of intussusception. RESULTS: The median age was 72 (range, 16-204) months, and 79 (53%) were boys. Diarrhea was the presenting symptom in 119 (79%) cases. A total of 45 intussusceptions were detected in 37 (25%) children. Out of 45 intussusceptions, 95% involved small bowel. All but one had asymptomatic intussusception. On GFD, intussusception resolved spontaneously within 7 days in 65%, within 14 days in 84%, and within 28 days in 92% of cases, and none required surgical or hydrostatic reduction. On univariate analysis, younger age, low weight z score, presentation with diarrhea, abdominal distension, rickets, lower serum albumin, more severe villous atrophy, and refeeding syndrome were more common in children with intussusception. On multivariate analysis, abdominal distension and hypoalbuminemia were found to be significantly associated with intussusception. CONCLUSIONS: Intussusception is frequently (25%) seen in children with newly diagnosed CD, generally asymptomatic and resolves spontaneously on GFD. It is often associated with more severe disease. Children with CD and intussusception should not be subjected to surgical/radiological intervention.

Minimal hepatic encephalopathy in children with chronic liver disease: Prevalence, pathogenesis and magnetic resonance-based diagnosis.

BACKGROUND & AIMS: Data on minimal hepatic encephalopathy (MHE) in children is scarce. We aimed to study MHE in children with chronic liver disease (CLD) and to validate non-invasive objective tests which can assist in its diagnosis. METHODS: We evaluated 67 children with CLD (38 boys; age 13 [7-18] years) and 37 healthy children to determine the prevalence of MHE. We also assessed the correlation of MHE with changes in brain metabolites by magnetic resonance spectroscopy (1HMRS), diffusion tensor imaging (DTI) derived metrics, blood ammonia and inflammatory cytokines (interleukin-6 [IL6], tumor necrosis factor alpha [TNF-α]). In addition, the accuracy of MR-based investigations for diagnosis of MHE in comparison to neuropsychological tests was analysed. RESULTS: Thirty-four (50.7%) children with CLD had MHE on neuropsychological tests. MHE patients had higher BA (30.5 [6-74] vs. 14 [6-66]µmol/L; p=0.02), IL-6 (8.3 [4.7-28.7] vs. 7.6 [4.7-20.7]pg/ml; p=0.4) and TNF-α (17.8 [7.8-65.5] vs. 12.8 [7.5-35]pg/ml; p=0.06) than No-MHE. 1HMRS showed higher glutamine (2.6 [2.1-3.3] vs. 2.4 [2.0-3.1]; p=0.02), and lower choline (0.20 [0.14-0.25] vs. 0.22 [0.17-0.28]; p=0.1) and myo-inositol (0.25 [0.14-0.41] vs. 0.29 [0.21-0.66]; p=0.2) in MHE patients than those without MHE. Mean diffusivity (MD) on DTI was significantly higher in 6/11 brain areas in patients with MHE vs. no MHE. Brain glutamine had a significant positive correlation with blood ammonia, IL-6, TNF-α and MD of various brain regions. Neuropsychological tests showed a negative correlation with blood ammonia, IL6, TNF-α, glutamine and MD. Frontal white matter MD had a sensitivity and specificity of 73.5% and 100% for diagnosing MHE. CONCLUSIONS: In children with CLD, 50% have MHE. There is a significant positive correlation between markers of hyperammonemia, inflammation and brain edema and these correlate negatively with neuropsychological tests. MD on DTI is a reliable tool for diagnosing MHE. LAY SUMMARY: Fifty percent of children with chronic liver disease develop minimal hepatic encephalopathy (MHE) and perform poorly on neuropsychological testing. These children have raised blood ammonia, inflammatory cytokines and mild cerebral edema on diffusion tensor imaging as compared to children without MHE. The higher the ammonia, inflammatory cytokines and cerebral edema levels the poorer the performance on neuropsychological assessment. The estimation of mean diffusivity on diffusion tensor imaging is an objective and reliable method for diagnosing MHE.
