Improving Transplant-free Survival With Low-volume Plasma Exchange to Treat Children With Rodenticide Induced Hepatotoxicity.

Background: In a prior report, no patient with rodenticidal hepatotoxicity who met Kochi criteria (MELD score ≥36 or baseline INR ≥6 with hepatic encephalopathy) (PMID: 26310868) for urgent liver transplantation survived with medical management alone. Plasma exchange (PLEX) may improve survival in these patients. Objectives: We describe our experience with low-volume PLEX (PLEX-LV) in treating rodenticide ingestion induced hepatotoxicity in children. Methods: From prospectively collected database of rodenticidal hepatotoxicity patients managed as in-patient with department of Hepatology from December 2017 to August 2021, we retrospectively studied outcomes in children (≤18 years). Hepatotoxicity was categorized as acute liver injury (ALI, coagulopathy alone) or acute liver failure (ALF, coagulopathy and encephalopathy). Kochi criteria was used to assess need for urgent liver transplantation. The primary study outcome was one-month survival. Results: Of the 110 rodenticidal hepatotoxicity patients, 32 children (females: 56%; age: 16 [4.7-18] years; median, range) constituted the study patients. The study patients presented 4 (1-8) days after poison consumption (impulsive suicidal intent:31, accidental:1). Twenty children (62%) had ALI [MELD: 18 (8-36)] and 12 (38%) had ALF [MELD: 37 (24-45)].All children received standard medical care, including N-acetyl cysteine; ALF patients also received anti-cerebral edema measures. None of the patient families opted for liver transplantation. Seventeen children (ALI: 6, ALF: 11) were treated with PLEX-LV (3 [1-5] sessions, volume of plasma exchanged per session: 26 [13-38] ml/kg body weight) and peri-procedure low dose prednisolone.At 1 month, 28 of the 32 children (87.5%) were alive (4 ALF patients died). Of 10 children who met Kochi listing criteria for urgent liver transplantation, two children were ineligible for PLEX-LV (due to hemodynamic instability) and of the remaining 8 children treated by PLEX-LV, 6 (75%) survived. Conclusions: PLEX-LV shows promise as an effective non-liver transplant treatment in children with rodenticidal hepatotoxicity.

Pancreatic, hepatobiliary, and gastrointestinal manifestations of children with cystic fibrosis: A 10-year experience from a tertiary care center in southern India.

OBJECTIVES: To describe the demography and spectrum of pancreatic, hepatobiliary, and gastrointestinal (GI) manifestations in children with cystic fibrosis (CF) from the Indian subcontinent. METHODS: In this retrospective study, relevant information from the database of all children with CF below 18 years of age was collected and analyzed. RESULTS: Among the total 109 children, 58 (53%) were from the southern states of India. The most common manifestation was pancreatic insufficiency (PI) in 85 (83%) children. Those with PI presented at an earlier age (1.8 vs. 6.9 years). Cirrhosis with portal hypertension was documented in only one patient and meconium ileus in three (2.8%). There was significant malnutrition in the PI cohort with a mean weight-for-age Z-score of - 3.17 ± 1.79 at diagnosis. Twenty-one (19%) patients had died during the follow-up and 18 (90%) of them had PI. There was no difference in the prevalence of selected pulmonary manifestations in the PI and pancreatic sufficient (PS) groups. Among children with PI, 78 were screened for ΔF508 mutation, 16 (21%) were homozygous, and 17 (22%) were heterozygous. In the PS group, only 2 (14%) were heterozygous for ΔF508 mutation. The median duration of follow-up of the patients was 1.8 (1.5) years. CONCLUSION: PI is the most common GI manifestation of children with CF and is associated with severe malnutrition and poor outcome. Timely identification and management of the comorbidities involving the digestive system are essential for better growth and quality of life in these children.

Accuracy and agreement of the Tuberculin Skin Test (TST) and the QuantiFERON-TB Gold In-tube test (QFT) in the diagnosis of tuberculosis in Indian children.

PURPOSE: Accurate diagnosis of TB in children is hampered by poor specificity of symptoms in endemic countries and the paucibacillary nature of childhood TB. This study was done to compare the accuracy and agreement of the tuberculin skin test (TST) and the QuantiFERON-TB Gold In-tube test (QFT) in diagnosing tuberculosis (TB) in a predominantly BCG-vaccinated population of children. METHODS: This retrospective cohort study enrolled all children aged 1-15 years who underwent TST and QFT testing as part of screening for TB. Children were classified according to the 2014 WHO case definition of TB, and statistical analysis was done to generate data on concordance between the TST and the QFT as well as sensitivity and specificity within WHO-defined groups. RESULTS: TST and QFT concordance was 83.9% overall (kappa 0.51), 79% in those with WHO-defined TB and 89% in those without TB. TST+/QFT-discordance was commoner than QFT+/TST- discordance across groups. The sensitivity of the TST vs. the QFT was 70.8% vs. 50% for WHO-defined TB, with comparable specificity at 89% vs. 90% respectively. CONCLUSIONS: The higher sensitivity of the cheaper and simpler TST supports its use for TB diagnosis in a normally nourished population of BCG-vaccinated children.

Effect of malnutrition in infants with cystic fibrosis in India: An underestimated danger.

AIMS: To assess the clinical profile and nutritional status of infants with cystic fibrosis (CF) and track their nutritional outcomes with treatment. MATERIALS AND METHODS: This retrospective study was conducted in a tertiary-care institute in South India. Demographic and clinical information were collected. The nutritional status and treatment outcome was assessed by Z-scores for weight-for-age (WAZ), length-for-age (LAZ), and weight-for-length (WLZ) at diagnosis and follow-up. RESULTS: Nineteen infants with CF had mean follow-up duration of 9.7 ± 8.7 months. There was a mean delay of 2.9 ± 2.1 months from symptom onset to diagnosis, by which time infants were severely malnourished (mean WAZ -4.68 ± 1.8). Pneumonia, summer dehydration with electrolyte abnormalities (42.1%), and a combination of anemia, hypoalbuminemia, and malnutrition (42.1%) were the predominant features. Significant weight loss had been recorded in undiagnosed infants by second month of life before symptom onset. At follow-up, there was a remarkable improvement in WAZ (P 0.001), but not LAZ and WLZ. There was a high mortality rate of 37% in these infants. CONCLUSIONS: Malnutrition is a significant morbidity in infants with CF in India. There was significant improvement of WAZ with treatment, but it lagged behind the recommended targets. There is an opportunity for identification of CF infants at the time of vaccination at six and ten weeks of age, by the primary care physician and pediatrician. Screening of young infants having failure to thrive in the immunization clinic may be a strategy for early diagnosis of infants with severe CF phenotype.

Multidrug-resistant Elizabethkingia anophelis Septicemia, Meningitis, Ventriculitis, and Hydrocephalus in a Preterm Neonate: A Rare Complication of an Emerging Pathogen.

Elizabethkingia anophelis is an emerging pathogen causing neonatal meningitis. Here, we describe the challenging course and necessity of a long 14-week duration of antibiotics in a 12-day-old male neonate with E. anophelis septicemia and meningitis. He developed ventriculitis and hydrocephalus, and needed a ventriculoperitoneal shunt. At 5-month follow-up he had developmental delay.
