Growth, tolerance and safety outcomes with use of an extensively hydrolyzed casein-based formula in infants with cow's milk protein allergy.

Objective: To evaluate growth, tolerance and safety outcomes with use of an extensively hydrolyzed casein-based formula (eHCF) in infants with cow's milk protein allergy (CMPA). Methods: A total of 226 infants (mean ± SD age: 106.5 ± 39.5 days, 52.7% were girls) with CMPA who received eHCF comprising at least half of the daily dietary intake were included. Data on anthropometrics [weight for age (WFA), length for age (LFA) and weight for length (WFL) z-scores] were recorded at baseline (visit 1), while data on infant feeding and stool records, anthropometrics and Infant Feeding and Stool Patterns and Formula Satisfaction Questionnaires were recorded at visit 2 (on Days 15 ± 5) and visit 3 (on Days 30 ± 5). Results: From baseline to visit 2 and visit 3, WFA z-scores (from -0.60 ± 1.13 to -0.54 ± 1.09 at visit 2, and to -0.44 ± 1.05 at visit 3, p < 0.001) and WFL z-scores (from -0.80 ± 1.30 to -0.71 ± 1.22 at visit 2, and to -0.64 ± 1.13 at visit 3, p = 0.002) were significantly increased. At least half of infants never experienced irritability or feeding refusal (55.7%) and spit-up after feeding (50.2%). The majority of mothers were satisfied with the study formula (93.2%), and wished to continue using it (92.2%). Conclusions: In conclusion, eHCF was well-accepted and tolerated by an intended use population of infants ≤ 6 months of age with CMPA and enabled adequate volume consumption and improved growth indices within 30 days of utilization alongside a favorable gastrointestinal tolerance and a high level of parental satisfaction.

Vitamin D Insufficiency in Children with Chronic Neurological Diseases: Frequency and Causative Factors.

Objective: Vitamin D insufficiency/rickets is a metabolic bone disease that leads to insufficient mineralization of bone. Chronic neurological diseases, including cerebral palsy (CP), convulsive disorders, neural tube defects, myopathy, immobility, lack of sun exposure, inadequate nutrition, and antiepileptic drugs (AEDs) can cause vitamin D insufficiency and osteopenia in children. Materials & Methods: In this study, the authors searched the frequency and causative factors of vitamin D insufficiency in children with chronic neurological diseases such as CP, hypoxic-ischemic encephalopathy, mental motor retardation, epilepsy, neurodegenerative and neuromuscular diseases, meningitis-encephalitis sequelae, neural tube defects, paralysis, and paresis. This cross-sectional study included 108 children (forty-five (41.6%) females; sixty-three (58.4%) males), aged between one and 18 years with chronic neurological diseases, and a control group of thirty age-matched healthy children (16 (53.3%) females; 14 (46.7%) males. Results: Vitamin D levels were significantly lower, and parathyroid hormone (PTH) levels were significantly higher in the patient group than in the control group (p<0.05). The patient group was divided into four subgroups: (i) Epilepsy (n=41; 38%), (ii) Neural tube defects (n=14; 13%), (iii) CP (n=21; 19%), and (iv) other diseases (neurodegenerative and neuromuscular diseases, meningitis sequelae, intracranial hemorrhage, psychomotor retardation, hypoxic-ischemic. encephalopathy) (n=32; 30%) to identify any differences in the measured levels. In the patient group, eighty-three (76.9%) had vitamin D deficiency, and 17 (15.7%) had vitamin D insufficiency, while in the control group, twenty-one (70%) had vitamin D insufficiency. The use of AEDs had no significant effect on serum Ca, P, ALP, PTH, or vitamin D levels (p>0.05), and serum Ca levels were significantly higher in ambulant patients than in non-ambulant patients (p<0.05). Vitamin D levels were significantly higher in the non-ambulant than in the ambulant patients (p<0.05). No rickets was determined in the control group, while in the patient group, nine (8.3%) had level-1 rickets, six (5.6%) had level-2 rickets, and two (1.9%) had level-3 rickets. Conclusion: Children with chronic neurological diseases have low serum vitamin D levels, and vitamin D prophylaxis is essential in this group.

All aspects of galactosemia: a single center experience.

OBJECTIVES: Classic galactosemia is a galactose metabolism disorder due to galactose-1-phosphate uridyltransferase deficiency. In this study we report the clinical features of a cohort of children with classic galactosemia. METHODS: A retrospective evaluation was made of the files of 42 cases followed up for a diagnosis of classic galactosemia between January 2000 and December 2021. The data were collected of clinical, laboratory and genetic characteristics. RESULTS: The cases comprised of 25 (59.5%) girls and 17 (40.5%) boys with a median age of 15 days (range, 1 day to 9 years) at diagnosis. In addition, thirty-six cases (92.3%) could be diagnosed before they were 4 months old by hospitalization with various clinical findings, primarily liver dysfunction. The most common complaints on presentation were jaundice (78.4%) and vomiting (27%) and the most frequently seen genetic pathogenic variant was c.563A>G (p.Gln188Arg) (92.4%). CONCLUSIONS: It can be emphasized that there is a need for a neonatal screening program for classic galactosemia to be able to increase the possibility of early diagnosis and to be able to start treatment before the development of a severe clinical picture.

Liver Involvement in Children during the Diagnosis of Celiac Disease: A Single-Center Experience from Turkey.

BACKGROUND: Liver abnormalities in Celiac disease (CD) are common. The aim of this study was to investigate the children with CD who were followed up in our clinic presenting with elevated aminotransferase levels. METHODS: In this study, the data of 419 pediatric patients with CD were retrospectively analyzed, and those with elevated aminotransferase levels during the diagnosis of CD were assessed. RESULTS: Elevation of aminotransferase levels was found in 66 (15.7%) patients among the 419 patients during the diagnosis of CD. The mean age of these patients was 7.33±3.96 years. Liver enzymes were mildly elevated in 63 (95.4%) patients. However, half of the patients with elevated liver enzymes had a 1.25-fold increase in aminotransferase levels. Patients with hypertransaminasemia had higher weight loss and lower folic acid values compared with patients with normal liver enzymes. Patients' liver tests were reverted to normal, except for two patients with chronic liver disease, after 9.27±3.16 months of administering a gluten-free diet. CONCLUSION: Patients with liver involvement should be investigated for CD. Especially, mildly elevation of aminotransferase levels should be taken into account by pediatricians for Celiac hepatitis.

Recommendations for Clinical Decision-making in Children with Type 1 Diabetes and Celiac Disease: Type 1 Diabetes and Celiac Disease Joint Working Group Report

It is well-known that in children with type 1 diabetes (T1D), the frequency of Celiac disease (CD) is increased due to mechanisms which are not fully elucidated but include autoimmune injury as well as shared genetic predisposition. Although histopathologic examination is the gold standard for diagnosis, avoiding unnecessary endoscopy is crucial. Therefore, for both clinicians and patients' families, the diagnosis of CD remains challenging. In light of this, a joint working group, the Type 1 Diabetes and Celiac Disease Joint Working Group, was convened, with the aim of reporting institutional data and reviewing current international guidelines, in order to provide a framework for clinicians. Several controversial issues were discussed: For CD screening in children with T1D, regardless of age, it is recommended to measure tissue transglutaminase-immunoglobulin A (tTG-IgA) and/or endomysial-IgA antibody due to their high sensitivity and specificity. However, the decision-making process based on tTG-IgA titer in children with T1D is still debated, since tTG-IgA titers may fluctuate in children with T1D. Moreover, seronegativity may occur spontaneously. The authors' own data showed that most of the cases who have biopsy-proven CD had tTG-IgA levels 7-10 times above the upper limit. The decision for endoscopy based solely on tTG-IgA levels should be avoided, except in cases where tTG-IgA levels are seven times and above the upper limit. A closer collaboration should be built between divisions of pediatric endocrinology and gastroenterology in terms of screening, diagnosis and follow-up of children with T1D and suspicious CD.

Familial Mediterranean Fever Mutation Analysis in Pediatric Patients With Inflammatory Bowel Disease: A Multicenter Study.

BACKGROUND: The aim of the study was to evaluate familial Mediterranean fever (FMF) mutation analysis in pediatric patients with inflammatory bowel disease (IBD). The relation between MEFV mutations and chronic inflammatory diseases has been reported previously. METHODS: Children with IBD (334 ulcerative colitis (UC), 224 Crohn's disease (CD), 39 indeterminate colitis (IC)) were tested for FMF mutations in this multicenter study. The distribution of mutations according to disease type, histopathological findings, and disease activity indexes was determined. RESULTS: A total of 597 children (mean age: 10.8 ± 4.6 years, M/F: 1.05) with IBD were included in the study. In this study, 41.9% of the patients had FMF mutations. E148Q was the most common mutation in UC and CD, and M694V in IC (30.5%, 34.5%, 47.1%, respectively). There was a significant difference in terms of endoscopic and histopathological findings according to mutation types (homozygous/ heterozygous) in patients with UC (P < .05). There was a statistically significant difference between colonoscopy findings in patients with or without mutations (P = .031, P = .045, respectively). The patients with UC who had mutations had lower Pediatric Ulcerative Colitis Activity Index (PUCAI) scores than the patients without mutations (P = .007). CONCLUSION: Although FMF mutations are unrelated to CD patients, but observed in UC patients with low PUCAI scores, it was established that mutations do not have a high impact on inflammatory response and clinical outcome of the disease.

Prevalence of Helicobacter pylori in children in eastern Turkey and molecular typing of isolates.

The objectives of the present study were to determine Helicobacter pylori via culture, polymerase chain reaction and histopathological diagnosis in 101 children ranging in age from 4 to 18 years, to identify the association among restriction fragment length polymorphism types and clinical disease and to investigate the relationships among different isolates of H. pylori in different age groups. We observed a high prevalence of H. pylori infections in children between the ages of 13 and 18 (75.8%), while children aged 4 to 6 years had the lowest prevalence of infection (40%). H. pylori was detected in 30.7% (31 of 101), 66.3% (67 of 101) and 63.2% (60 of 95) of children as determined by culture methods, PCR and histological examination, respectively. H. pylori isolates with RFLP types I and III were the most common among children with antral nodularity, whereas RFLP types II and IV were the least detected types. Interestingly, all isolates from peptic ulcer patients were type III. Although our results show a high prevalence of H. pylori infections in the pediatric population in eastern Turkey, no association was identified between H. pylori infection with antral nodularity and recurring abdominal pain. In addition, we found low genetic variation among H. pylori isolates from children and no association between RFLP types and antral nodularity (p > 0.05). Additionally, we found that H. pylori isolates with specific RFLP types were predominant in different age groups.

Gastrointestinal system lesions in children due to the ingestion of alkali and acid corrosive substances.

BACKGROUND/AIM: TO examine esophageal and gastric lesions in children due to the ingestion of alkali and acid corrosive substances and to emphasize all related complications. MATERIALS AND METHODS: The reports of 103 children who ingested or were suspected to have ingested corrosive substances and who then underwent upper gastrointestinal endoscopic inspections were evaluated retrospectively. RESULTS: Of the patients, the mean age was 41 ± 3.6 months, and 57.3% were male. Vomiting was the most common symptom (44.7%). Eighteen different commercial products were defined as corrosive substances: 59.2% of them were alkali, 39.8% were acids, and 1% had a neutral pH. These corrosive agents most frequently contained sodium hydroxide, followed by hydrochloric acid, sodium hypochlorite, and sulfuric acid. Endoscopic inspections were abnormal in 68% of the cases. Esophageal lesions were observed in 56.3% of the patients, while gastric lesions were observed in 35%. During the follow-up period, esophageal strictures developed in 4.9% of patients, while gastric outlet obstructions developed in 1%. CONCLUSION: Of the patients, the mean age was 41 ± 3.6 months, and 57.3% were male. Vomiting was the most common symptom (44.7%).

The importance of the serum quantitative levels of hepatitis B surface antigen and hepatitis B e antigen in children with chronic hepatitis B.

BACKGROUND/AIMS: We aimed to investigate the clinical importance of quantitative levels of serum hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg), and to detect their correlation with hepatitis B virus (HBV) DNA load, alanine aminotransferase (ALT) levels, hepatic activity index (HAI) and fibrosis scores. MATERIALS AND METHODS: A total of 56 HBeAg-positive children with chronic hepatitis B (CHB) were included in the study. Quantification of HBsAg and HBeAg was performed using an automated chemiluminescent microparticle immunoassay. Comparisons were performed using the paired t-test, Mann-Whitney U test or t-test for independent samples. Correlations were tested using the Pearson correlation analysis. RESULTS: Significant differences were found between groups of pre- and post treatment quantitative levels of HBsAg, HBeAg, HBV DNA, and ALT. Comparison of HBsAg, HBeAg, HBV DNA, and ALT levels before the treatment and decrease ratios of these levels after treatment according to HAI and fibrosis scores did not show any statistically significant differences. There was a positive correlation between pretreatment HBV DNA load and HBeAg levels, and a negative correlation between pretreatment HBV DNA and ALT levels. There was a negative correlation between decrease ratios of HBsAg and ALT levels after treatment. Patients with post treatment HBeAg seroconversion had a lower post treatment HBV DNA load and a higher decrease ratio of HBsAg than patients who did not have HBeAg seroconversion. CONCLUSION: The present study indicated that HBsAg and HBeAg levels significantly decreased during treatment and that HBeAg correlated with HBV DNA load. Quantitative HBeAg and HBsAg assays could therefore have an important role in treatment of CHB.

Is cervical inlet patch important clinical problem?

AIM: In this study we aim to determine the frequency of Inlet Patch (IP) and its association to clinical symptoms and draw attention to be aware of this heterotopic gastric mucosa. METHODS: This study was a prospective case series that IP was detected in the upper gastrointestinal endoscopy. Patients with laringopharyngeal reflux symptoms underwent endoscopy between March 2009 and July 2012 in two different institutions. All the biopsies were obtained from if there is the IP lesion and antral or/and gastric mucosa. The data was prospectively evaluated. The prevalence was compared with those of patients that did not determine IP in the study period. RESULTS: 3907 upper gastrointestinal system endoscopy was performed while 123 patients consist of 51 male and 72 female was determined as IP. The prevalence of IP in patiens who underwent upper gastrointestinal endoscopy was 3.14% in our study. The majority of symptoms of those who had IP were laringopharyngeal reflux symptoms. Heterotopic gastric mucosa was fixed in 114 cases while 28 chronic inflammation, 9 esophagitis, 5 intestinal metaplasia, 4 glicogenic acanthosis were obtained as additional findings in pathological examinations. CONCLUSION: Heterotopic gastric mucosa in the proximal esophagus is a frequent finding if the endoscopist is aware of this entity. The importance of IP is the increasing number of cases of neoplastic transformation. Symptomatic patients should be treated and should be considered of the complications of heterotopic gastric mucosa.

Enhanced postoperative recovery pathways in emergency surgery: a randomised controlled clinical trial.

BACKGROUND: Enhanced recovery pathways are now widely used in elective surgical procedures. The feasibility of enhanced postoperative recovery pathways in emergency surgery for perforated peptic ulcer disease was investigated in this randomized controlled clinical trial. METHODS: Patients with perforated peptic ulcer disease who underwent laparoscopic repair were randomized into 2 groups. Group 1 patients were managed with standard postoperative care and group 2 patients with enhanced postoperative recovery pathways. The primary endpoints were the length of hospital stay and morbidity and mortality. RESULTS: Forty-seven patients were included in the study. There were 26 patients in group 1 and 21 in group 2. There were no significant differences in the morbidity and mortality rates, whereas the length of hospital stay was significantly shorter in group 2. CONCLUSIONS: The application of enhanced postoperative recovery pathways in selected patients with perforated peptic ulcer disease who undergo laparoscopic Graham patch repair seems feasible.

Protective effects of L-carnitine, N-acetylcysteine and genistein in an experimental model of liver fibrosis.

AIM: Liver fibrosis is a reversible wound-healing response that occurs following liver injury. In this study, we aimed to investigate the possible protective effects of L-carnitine, N-acetylcysteine and genistein in liver fibrosis induced by carbon tetrachloride (CCl4). In addition, the effects of these agents were compared in the same study. METHODS: In this study, rats were randomly allocated into 8 groups, consisting of 10 rats each, as follows: a control group, CCl4, L-carnitine, N-acetylcysteine, genistein, CCl4 and L-carnitine, CCl4 and N-acetylcysteine, and CCl4 and genistein. At the end of 6 weeks, blood and liver tissue specimens were collected. Alanine aminotransferase (ALT); aspartate aminotransferase (AST); complete blood count, tumor necrosis factor-α (TNF-α); platelet-derived growth factor-BB (PDGF-BB); interleukin-6 (IL-6); liver glutathione level; oxidant/antioxidant status; scores of hepatic steatosis, necrosis, inflammation, and fibrosis; and the expression of α-smooth muscle actin were studied. RESULTS: Although the ALT and AST values in the group administered CCl4 were significantly higher than in all the other groups (P<0.05), there was no significant difference between the control group and the groups administered CCl4 combined with L-carnitine, N-acetylcysteine and genistein (P>0.05). There were significant differences in the levels of TNF-α, PDGF-BB and IL-6 (P<0.05) between the CCl4 group and the groups with L-carnitine, N-acetylcysteine and genistein added to CCl4. N-acetylcysteine and genistein had positive effects on the oxidant/antioxidant status and on liver necrosis and fibrosis scores. CONCLUSIONS: In our study, L-carnitine, N-acetylcysteine and genistein showed significant protective effects in liver fibrosis induced by CCl4.

Prevalence of Helicobacter pylori virulence genotypes among children in Eastern Turkey.

AIM: To identify the virulence genotypes of Helicobacter pylori (H. pylori) if present in children in Eastern Turkey and if those genotypes are mostly associated with severe clinical presentations. METHODS: A total of 49 H. pylori positive Turkish children (42 with antral nodularity and 7 with peptic ulcer) who underwent upper gastrointestinal endoscopy with abdominal symptoms during the period from March 2011 to September 2012 were enrolled in this study. Antral nodularity was diagnosed endoscopically by two of the authors. We determined for the presence of cagA, vacA, cagE, iceA and babA2 genotypes of H. pylori isolates in DNA obtained directly from frozen gastric biopsy samples by polymerase chain reaction test using specific primers. RESULTS: Of the 49 H. pylori isolates studied, 61.2%, 91.8%, 22.4%, 28.6%, 57.1% and 40.8% were positive for the cagA, vacA s1, cagE, iceA1, iceA2 and babA2 genes, respectively. We showed that the most common vacA subtype was s1a (79.6%). However, the s2 gene was found less frequently with an isolation rate of 8.2% of the H. pylori isolates. The genotypes iceA2 and vacA s1m2 were the most frequently found types in children with antral nodularity. In addition, the genotypes iceA1, babA2 and vacA s1m1 were found in similar ratios in all the H. pylori isolates obtained from children with peptic ulcer. The genotypes vacA s2m1 and s1c were not observed in any of isolates studied. CONCLUSION: This study showed that vacA s1m2, cagA and iceA2 were the most common genotypes, and no association between antral nodularity and genotypes was observed.

Lactoferrin levels in the gastric tissue of Helicobacter pylori-positive and -negative patients and its effect on anemia.

AIM: To determine gastric tissue lactoferrin (Lf) levels of Helicobacter pylori- (Hp-) positive and -negative patients and its effect on anemia. METHODS: Cases in which initial presentation was of abdominal pain and that were Hp-positive at endoscopy were included. Hp-positive cases and -negative controls were divided into two groups. RESULTS: The study included 64 cases (average: 10.2 ± 0.4 years, 39 male and 25 female). Lf levels were subsequently studied on 61 cases. 45 (73.8%) of these were Hp-positive, while 16 (22.2%) were Hp-negative. In Hp-positive cases, mean staining percentages and density of glands in the antral mucosa were 45.5 ± 4.7% and 1.9 ± 0.1, respectively. Hp-negative cases showed significantly different values of 17.8 ± 4.5% and 1.3 ± 0.2, respectively. Hemoglobin and serum ferritin values of Hp-positive cases were 12.7 ± 0.2 g/dL and 32.5 ± 2 ng/mL, but these were comparable with Hp-negative cases (12.6 ± 0.1 g/dL and 30.7 ± 4.4 ng/mL). CONCLUSIONS: Tissue Lf was significantly higher in Hp-positive cases compared to Hp-negative cases, but no difference was observed between the two groups with regards to hemoglobin and ferritin level. As a result, it is difficult to say that this rise in Lf plays a role in the development of iron deficiency anemia in Hp-positive patients.

Prevalence of celiac disease among first-degree relatives of patients with celiac disease.

OBJECTIVES: Celiac disease, an autoimmune enteropathy that affects the proximal small intestine, is characteristically seen in people who have a genetic susceptibility to gluten sensitivity. Celiac patients' first-degree relatives are more at risk of acquiring the disease. The objective of the present study was consequently to determine the prevalence of celiac disease in a group of first-degree relatives of our patients with celiac disease. METHODS: First-degree relatives of 195 patients with celiac disease attending a gastroenterology unit underwent serologic screening. Antitissue transglutaminase (anti-tTG) immunoglobulin A (IgA) and total serum IgA tests were used for first-level screening. Duodenal biopsy was recommended to subjects showing positive results to anti-tTG IgA testing. Biopsy samples were obtained by endoscopy, and biopsy specimens were evaluated and classified according to Marsh classification. RESULTS: Positive anti-tTG IgA was found in 46 first-degree relatives (9.5%), whereas serum IgA levels were normal. Of 46 serology-positive relatives, 34 agreed to the endoscopy procedure. Histological changes characteristic of celiac disease were found in 23 subjects. The prevalence of celiac disease among the first-degree relatives was found to be at least 4.8%. Of 34 subjects that underwent biopsy, 11 were evaluated as Marsh 0, 5 as Marsh 1, 4 as Marsh 2, 12 as Marsh 3, and 2 as Marsh 4. Of the biopsy-positive subjects, 3 were mothers, 1 was a father, and 19 were siblings. CONCLUSIONS: The present study identified 23 undiagnosed cases of celiac disease among 484 first-degree relatives of 195 patients with celiac disease, confirming the high prevalence (4.8%) of the disease in this specific group. It is suggested that an extensive screening policy be mandatory for these subjects.

[Case report: primary splenic hydatidosis]. / Olgu Sunumu: primer dalak kist hidatigi.

Hydatidosis, caused by Echinococcus granulosus is still an important problem in endemic areas as Middle and Eastern Europe including Turkey, South America, Avustralia, New Zealand and South Africa. Hydatid disease affects more common liver and lung. Isolated splenic hydatidoses are quite rare in the medical literature. Here we report a case of isolated primary splenic hydatid cyst which is treated by splenectomy.
