Indian Academy of Pediatrics Consensus Guidelines for Probiotic Use in Childhood Diarrhea

Justification: Several probiotic species and strains, single or combined, have been evaluated in childhood diarrheal disorders, and recommendations have ever been changing as newer trials are published. Therefore, there is a need to develop a guideline for Indian children describing the current role of probiotics in clinical practice. Objectives: To develop a guideline for the use of probiotics in children with diarrhea. Process: A national consultative group (NCG) was constituted by the Indian Academy of Pediatrics (IAP), consisting of subject experts. Sub-topics were allotted to various experts as paired groups for detailed review. Members reviewed the international and Indian literature for existing guidelines, systematic reviews, meta-analyses and trials. Thereafter, two virtual structured meetings of the group were held on 2nd and 22nd August, 2020. The management guidelines were formulated by the group and circulated to the participants for comments. The final guidelines were approved by all experts, and adopted by the IAP executive board. Recommendations: The NCG suggests Lactobacillus GG as a conditional recommendation with low-to-moderate level evidence or Saccharomyces boulardii as a conditional recom-mendation with very low-to-low level evidence as adjuvant therapy in acute diarrhea. The NCG also recommends the use of combination probiotics in neonatal necrotizing enterocolitis (NEC), as these reduce the risk of NEC stage II and above, late-onset sepsis, mortality and also time to achieve full feeds. The NCG does not recommend the use of any kind of probiotics in the therapy of acute dysentery, persistent diarrhea, Clostridium difficile diarrhea and chronic diarrheal conditions such as celiac disease, diarrheapredominant irritable bowel syndrome and inflammatory bowel disease in children. Risk of antibiotic-associated diarrhea (AAD) is high with some antibiotics and most of these cases present as mild diarrhea. The NCG recommends probiotics only in special situations of AAD. L. rhamnoses GG or S. boulardii may be used for the prevention of AAD. VSL#3, a combination probiotic, may be used as an adjuvant in active pouchitis, and for prevention of recurrences and maintenance of remission in pouchitis.

Management of Childhood Functional Constipation: Consensus Practice Guidelines of Indian Society of Pediatric Gastroenterology, Hepatology and Nutrition and Pediatric Gastroenterology Chapter of Indian Academy of Pediatrics

Justification: Management practices of functional constipation are far from satisfactory in developing countries like India; availableguidelines do not comprehensively address the problems pertinent to our country.Process: A questionnaire-based survey was conducted among selected practising pediatricians and pediatric gastroenterologists inIndia, and the respondents agreed on the need for an Indian guideline on the topic. A group of experts were invited to present thepublished literature under 12 different headings, and a consensus was developed to formulate the practice guidelines, keeping in viewthe needs in Indian children.Objective: To formulate practice guidelines for the management of childhood functional constipation that are relevant to Indian children.Recommendations: Functional constipation should be diagnosed only in the absence of red flags on history and examination. Thosewith impaction and/or retentive incontinence should be disimpacted with polyethylene glycol (hospital or home-based). Osmoticlaxatives (polyethylene glycol more than 1 year of age and lactulose/lactitol less than 1 year of age) are the first line of maintenancetherapy. Stimulant laxatives should be reserved only for rescue therapy. Combination therapies of two osmotics, two stimulants or twoclasses of laxatives are not recommended. Laxatives as maintenance therapy should be given for a prolonged period and should betapered off gradually, only after a successful outcome. Essential components of therapy for a successful outcome include counselling,dietary changes, toilet-training and regular follow-up.

Classical Galactosemia Among Indian Children: Presentation and Outcome from a Pediatric Gastroenterology Center.

Objective: To analyze the presentation and predictors of outcome of children with galactosemia. Methods: Analysis of clinical, laboratory, microbiological profile and outcome of patients fulfilling the diagnostic criteria: i) clinical setting; ii) reduced erythrocyte Gal-1-PUT enzyme activity; and iii) unequivocal response to lactose-free diet. Results: 24 patients; median age of symptom onset and diagnosis: 10 (3-75) d and 55 (15-455) days, respectively. 71% had uncorrectable coagulopathy; 71% systemic infections; and 54% had ascites. Outcome: consisted of 87.5% survival with normalization of liver function tests at 5.5 (1-24) months follow-up. Conclusion: Despite delayed referral, high Pediatric end-stage liver disease scores and systemic infections, long-term outcome in galactosemia is rewarding. A subset of children have developmental delay.

Management of Acute Liver Failure in Infants and Children: Consensus Statement of the Pediatric Gastroenterology Chapter, Indian Academy of Pediatrics.

Process: Selected members were requested to prepare guidelines on specific issues, which were reviewed by two other members. These guidelines were then incorporated into a draft statement, which was circulated to all members. On 17th December 2011, Kunwar Viren Oswal round table conference was organized by the Apollo Center for Advanced Pediatrics, Indraprastha Apollo Hospital, New Delhi and the Sub-specialty Chapter of Pediatric Gastroenterology, Indian Academy of Pediatrics. Presentations, ensuing discussions, and opinions expressed by the participants were incorporated into the final draft. Objectives: To formulate comprehensive evidence based guidelines for management of acute liver failure in India, Recommendations: Viral hepatitis is the leading cause of acute liver failure (ALF) in India. Search for metabolic etiology, particularly in infants and neonates, and in apparently idiopathic cases needs to be done. Planning for early transfer is important as the risks involved with patient transport may increase or even preclude transfer at later stages. Management should be in an intensive care setting in select situations. There is currently insufficient evidence to routinely prescribe branched-chain amino acids, non-absorbable antibiotics or lactulose. Group recommends use of N-acetyl cysteine routinely in patients with ALF. Administration of antibiotics is recommended where infection is present or the likelihood of impending sepsis is high. Enteral nutrition is preferred to parenteral nutrition. Protein restriction is not recommended. An international normalized ratio >4 or Factor V concentration of <25% are the best available criteria for listing for liver transplantation. Overall 40-50% of ALF patients survive without transplantation. Survival in patients fulfilling criteria for liver transplantation and not transplanted is 10-20%. Liver transplantation is a definite treatment for ALF with high one-and five-year survival rates.

Time to recognize atypical celiac disease in Indian children.

BACKGROUND/OBJECTIVE: There is scant information about atypical (non-diarrheal) presentation of celiac disease (CD) from India. We conducted this study to compare non-diarrheal and diarrheal presentations of CD in children. METHODS: From November 2003 to December 2005, we prospectively screened two groups of children for CD, group I with diarrhea and group II without diarrhea but with atypical presentations (unexplained growth retardation, refractory anemia, refractory rickets, chronic constipation and abdominal distension). Screening was done with IgA antiendomysial antibody (EMA) followed by duodenal biopsy if EMA was positive. Celiac disease was diagnosed according to modified ESPGHAN criteria. RESULTS: A total of 200 children were screened (103 in group I and 97 in group II) and CD was diagnosed in 42 (classical 24, atypical 18). Presentation of atypical CD were; short stature 6, anemia 4, abdominal distension 3, rickets 2, and constipation, diabetes mellitus, delayed puberty in 1 case each. Patients with atypical CD were older (median age 10.4 years vs 5.5 years, p< 0.007) than classical cases. On mean (SD) follow-up of 12.6 (7.5) months all showed response to gluten-free-diet, and median gain in weight, height and final hemoglobin levels were similar in the two groups. CONCLUSION: Atypical CD is not uncommon in India. Children with atypical CD present at an older age. Likelihood of finding CD is high in children with anemia, short stature and rickets.

Helicobacter pylori in children: an Indian perspective.

Helicobacter pylori is causally associated with peptic ulcer disease and gastric carcinoma. Typically children get infected with this organism during the first decade of life but diseases, associated with H. pylori, are seen mainly in adults. In India, almost 80% of population is infected with H. pylori and most of them by 10 years of age. Hence, it is important for a pediatrician to know when to suspect this infection, how to investigate and how to treat it. Extensive electronic (PubMed) literature search was done for this review and literature (randomized controlled trials, clinical trials, meta-analysis, practice guidelines) related to H. pylori in children were reviewed. Special emphasis was given to Indian studies. From this review we can conclude that H. pylori infection is very common in Indian children especially in the low socioeconomic status but most infected children remain asymptomatic through out their childhood and about 15% develop peptic ulcer disease as young adults and 1% develop gastric cancer in older age. There is no association, what so ever, of H. pylori infection and recurrent abdominal pain (RAP). Endoscopy is the preferred method of investigation in children with upper digestive symptoms suggestive of organic disease. Children with H. pylori related disease (peptic ulcer, primary gastric B-cell lymphoma and atrophic gastritis with intestinal metaplasia) but not mere H. pylori infection should be treated with the triple drug regimen comprising of proton pump inhibitor (PPI) and two antibiotics for two weeks.

Celiac disease in India.

This review of the current scenario of celiac disease (CD) in India covers both pediatric and adult CD. CD is primarily reported from northern India with isolated case reports from the rest of the country. CD cases among Indian children are associated with multiple DR3-DQ2 haplotypes. Delay in diagnosis is contributed by multiple factors including atypical presentations. Use of serological tests, IgA EMA and anti-tTG antibodies, along with modified ESPGHAN criteria provides a definitive diagnosis of CD. Dietary management is often difficult due to non-availability of labeled and marketed gluten-free foods. A majority of children with CD show normalization of nutrition, substantial improvement in growth parameters and attainment of healthy percentile curves on gluten-free diet. Small bowel histology remarkably improves but does not normalize even after 2-3 years on gluten-free diet. The true burden of the disease should be addressed by large epidemiological studies.

Ascites in childhood liver disease.

Ascites is a common clinical problem in children with liver disease. The peripheral arterial vasodilation hypothesis is mostly accepted as the pathophysiological basis of ascites. The most important complication is spontaneous ascitic fluid infection in the form of spontaneous bacterial peritonitis (SBP) and its variants. Aerobic gram-negative bacteria, primarily Escherichia coli, are the most common isolates. Diagnostic paracentesis is done in patients with ascites when diagnosed first time and at the beginning of each admission to hospital. Ascitic fluid is evaluated for cell count with differential, albumin level, total protein and culture. Serum-ascites albumin gradient (SAAG) is the best single test for classifying ascites into portal hypertensive (SAAG> 1.1 g/dL) and non-portal hypertensive (SAAG < 1.1 g/dL) causes. In patients with tense ascites LVP should be performed. A neutrophil count of > 250 cells/mm3 is highly suggestive of bacterial peritonitis. Intravenous cefotaxime is the empiric antibiotic of choice. Long-term administration of oral norfloxacin 5-7.5 mg/Kg once a day in cirrhotic patients with ascitic fluid protein content of < 1g/dL or prior episode of SBP is recommended for prevention of SBP. Oral dual diuretic therapy of single morning dose of spironolactone along with furosemide in the ratio of 5:2 is recommended. While obtaining satisfactory diuretic response dual diuretic therapy can be changed over to monotherapy with spironolactone. Patients should be on sodium restricted diet. Management of ascites might ultimately require liver transplantation.

Antibody testing in Indian children with celiac disease.

BACKGROUND: We prospectively evaluated the usefulness of IgA tissue transglutaminase antibodies (IgA tTG) in the initial diagnosis of celiac disease (CD) and compared its diagnostic potential with that of IgA anti-endomysial antibodies (IgA EMA) and anti-IgA and IgG gliadin antibodies (AGA and AGG, respectively). METHODS: Sera of 23 untreated children fulfilling the revised ESPGHAN criteria for diagnosis of CD (Group I; mean age 10.8 y); 19 disease controls (Group II; mean age 8.5 y) presenting with chronic diarrhea, short stature or both; and 22 healthy children (Group III; mean age 8.8 y) were studied. These were tested in a blinded manner for AGA, AGG, IgA tTG (guinea pig as antigen) and IgA EMA. RESULTS: In Group I, IgA EMA was positive in 19, IgA tTG in 17, AGA in 14 and AGG in 17 patients. In Group II, these tests were positive in 1, 0, 2 and 14 patients, respectively and in Group III, in 0, 0, 0 and 1 child, respectively. Analyzing data from Group I and II, IgA EMA, IgA tTG, AGA and AGG had sensitivity rates of 83%, 74%, 61% and 74%, respectively; the specificity rates were 95%, 100%, 89% and 26%; positive predictive values were 95%, 100%, 88% and 55% and negative predictive values were 82%, 74%, 65% and 45%, respectively. CONCLUSION: IgA tTG is useful for the diagnosis of CD, with sensitivity and specificity rates comparable to those of EMA and this test is well suited for use in tropical countries like India.
