Recurrent acute pancreatic attacks is a rare clinical condition (2-5% of all acute pancreatis) in children and is mainly idiopathic in most cases. Sometimes it may be associated with congenital anomalies, metabolic diseases or hereditary conditions. Isovaleric acidemia (IVA) is a rare autosomal recessive amino acid metabolism disorder associated with isovaleryl coenzyme A dehydrogenase deficiency presenting the clinical findings such metabolic acidosis with increased anion gap, hyperammonemia, ketonemia, hypoglycemia, “the odor of sweaty feet,” abdominal pain, vomiting, feeding intolerance, shock and coma. Recurrent acute pancreatitis associated with IVA have been rarely reported. Herein; we report a child who admitted with recurrent acute pancreatic attacks and had the final diagnosis of IVA. Mutation analysis revealed a novel homozygous mutation of (p.E117K [c.349G>A]) in the IVA gene. Organic acidemias must kept in mind in the differential diagnosis of recurrent acute pancreatic attacks in children.

PURPOSE: Alpha-1 antitrypsin deficiency (A1ATD) in one of the most common genetic causes of liver disease in children. We aimed to analyze the clinical characteristics and outcomes of patients with A1ATD.METHODS: This study included patients with A1ATD from five pediatric hepatology units. Demographics, clinical findings, genetics, and outcome of the patients were recorded (n=25).RESULTS: Eight patients (32.0%) had homozygous PiZZ genotype while 17 (68.0%) had heterozygous genotype. Patients with PiZZ genotype had lower alpha-1 antitrypsin levels than patients with PiMZ genotype (37.6±7.7 mg/dL vs. 66.5±22.7 mg/dL, p=0.0001). Patients with PiZZ genotype were diagnosed earlier than patients with PiMZ genotype, but this was not significant (13±6.8 months vs. 23.7±30.1 months, p=0.192). Follow-up revealed the death of one patient (12.5%) with a homozygous mutation, and revealed that one patient had child A cirrhosis, five patients (62.5%) had chronic hepatitis, and one patient (12.5%) was asymptomatic. Nine of the 17 patients with a heterozygous mutation had chronic hepatitis (52.9%), two (11.7%) had child A cirrhosis, and six (35.2%) were asymptomatic. Overall, 18 (72%) of the 25 children had liver pathology in the long-term.CONCLUSION: Although prevalence is rare, patients with liver disorders should be checked for alpha-1 antitrypsin levels. Moreover, long-term follow-up is essential because most patients have a liver pathology.

Purpose:
The gastrointestinal system is the most commonly affected organ, followed by the lungs, in patients with primary immunodeficiency disease (PID). Hence, it is common for children with PIDs to present with gastrointestinal symptoms. We aimed to analyze the clinical and histopathological findings of patients who were initially admitted to pediatric gastroenterology/hepatology clinics and subsequently diagnosed with PIDs to identify the clinical clues for PIDs.
Methods:
The demographic, laboratory, and histopathological findings, treatment modality, and outcomes of patients initially admitted to the pediatric gastroenterology/hepatology unit and subsequently diagnosed with PIDs were recorded.
Results:
The study included 24 patients (58.3% male; median age [range]: 29 [0.5–204] months). Common clinical presentations included chronic diarrhea (n=8), colitis (n=6), acute hepatitis (n=4), and acute liver failure (n=2). The association of autoimmune diseases, development of malignant diseases, and severe progression of viral diseases was observed in 20.8%, 8.3%, and 16.6% of the patients, respectively. Antibody deficiency was predominantly diagnosed in 29.2% of patients, combined immunodeficiency in 20.8%, immune dysregulation in 12.5%, defects in intrinsic and innate immunity in 4.2%, autoinflammatory disorders in 8.3%, and congenital defects of phagocytes in 4.2%. Five patients remained unclassified (20.8%).
Conclusion
Patients with PIDs may initially experience gastrointestinal or liver problems. It is recommended that the association of autoimmune or malignant diseases or severe progression of viral diseases provide pediatric gastroenterologists some suspicion of PIDs. After screening using basic laboratory tests, genetic analysis is mandatory for a definitive diagnosis.

BACKGROUND/AIMS: Ischemia-modified albumin (IMA) levels have been shown to correlate with the severity of liver failure in adults. However, the role of IMA levels has not been evaluated in children with chronic liver disease (CLD). We analyzed the clinical significance of IMA levels in children with CLD. METHODS: Thirty-three children with CLD and 33 healthy children were included in the study. Blood was collected to analyze biochemical parameters, oxidant status, and IMA. Liver biopsies were re-evaluated for liver fibrosis; severe fibrosis (SF) was defined as fibrosis stage > or =4. RESULTS: The IMA and and IMA to albumin ratios (IMARs) were significantly higher in children with CLD than in those without (IMA: 0.545+/-0.095 vs 0.481+/-0.062, p=0.003; IMAR: 0.152+/-0.046 vs 0.126+/-0.018, p=0.04). The IMAR was positively correlated with the pediatric end-stage liver disease score (p=0.03, r=0.503) and fibrosis score (p=0.021, r=0.400). Patients with SF had higher IMARs compared to patients with mild fibrosis (0.181+/-0.056 vs 0.134+/-0.025, p=0.003). The area under the receiver operation curve (AUROC) for predicting SF was 0.78 (p=0.006). Using a cutoff ratio value of 0.140, the sensitivity and specificity were 84% and 70%, respectively. The AUROC for predicting the need for liver transplantation and/or death was 0.82 (p=0.013). With a cutoff value of 0.156, the sensitivity and specificity was 83% and 82%, respectively. Kaplan-Meier analysis revealed increased morbidity and/or mortality in the group with an IMAR>0.156 (50% vs 4.3%, p=0.005). CONCLUSIONS: IMARs have been shown to provide important clues in predicting the fibrosis stage of the disease and determining the outcome in children with CLD.

PURPOSE: Malnutrition may influence neurocognitive development in children by directly affecting the brain structural development, or indirectly by affecting the children's cognition experience. Malnutrition alters the cell numbers, cell migration, synaptogenesis, and neurotransmission due to inadequate availability of necessary micronutrients to support cell growth. We aimed to analyze neurocognitive development in infants with malnutrition and its association with long chain polyunsaturated fatty acids (LC-PUFA), micronutrients levels and magnetic resonance spectroscopy (MRS) findings. METHODS: The study included two groups; group 1, infants with malnutrition (n=24), group 2; healthy infants (n=21). Peripheral blood was obtained from the participants for studying micronutrients and LC-PUFA levels. The neurocognitive development was analyzed by the use of an Ankara Developmental Screening Inventory test. MRS were performed on all infants. RESULTS: All parameters of neurocognitive development and serum calcium (9.6±0.9 mg/dL vs. 10.4±0.3 mg/dL, p < 0.05) and magnesium (2.02±0.27 mg/dL vs. 2.2±0.14 mg/dL, p < 0.05) levels were noted as being low in infants with marked malnutrition. No difference was found in LC-PUFA levels between healthy and malnourished infants. Thalamic choline/creatine levels were significantly high in infants with malnutrition (1.33±0.22 vs. 1.18±0.22, p < 0.05). Total neurocognitive development in infants was positively correlated with serum calcium levels (p < 0.05, r=0.381). CONCLUSION: Calcium supplementation may improve neurocognitive development in malnourished infants.
