RESUMO
BACKGROUND: The neutrophil-to-lymphocyte ratio (NLR) is a simple and inexpensive inflammation biomarker that reflects systemic inflammation based on complete blood count values. AIMS: In our study, we aimed to compare the NLR values in pediatric inflammatory bowel disease (IBD) and in healthy controls, and to define NLR levels in children with IBD during diagnosis, active disease, and remission. METHODS: NLR values of patients with IBD at diagnosis, remission, and active disease of the patients were recorded retrospectively. Age- and sex-matched healthy subjects enrolled as the control group. RESULTS: Sixty-three patients with IBD and 92 healthy subjects as the control group enrolled. The mean age of the patients with IBD was 9.31 ± 5.24 years, and 57.1% were males. The mean NLR values of the patients with IBD at diagnosis and remission were significantly higher than that of healthy controls (p < 0.001). The mean NLR values of the patients at diagnosis and active disease were significantly higher than that of during remission (p < 0.001). The best cutoff of NLR for prediction of diagnosis of IBD in children was 1.46 with a sensitivity of 86.2% and specificity of 93.5%. There was no significant difference regarding NLR between patients with IBD with and without associated diseases. At diagnosis the mean NLR level of patients with Crohn's disease was significantly higher than that of ulcerative colitis (p = 0.019). CONCLUSIONS: It was shown for the first time that NLR levels were significantly increased at diagnosis and active disease of childhood IBD, compared to the remission period. We believe that NLR can be a non-invasive inflammatory biomarker that should be used in the initial evaluation and follow-up of the disease activity in children.

BACKGROUND: Nutritional status in primary immunodeficiencies (PID) is a major factor influencing immune defense. We aimed to evaluate the nutritional status of patients with PID. METHODS: Demographic findings and anthropometric measurements of 104 patients were recorded for this cross-sectional study. RESULTS: Combined immunodeficiencies (n = 49), predominantly antibody deficiencies (n = 28) and phagocytic system disorders (n = 17), were the major disease groups. In total, 44 (42.3%) patients had at least one anthropometric measurement below -2 standard deviations. Chronic, acute, and mixed-type malnutrition were detected in 18.3%, 16.3%, and 7.7% of the patients, respectively. No significant difference was detected among groups regarding anthropometric measurements however higher malnutrition rates were observed in 'combined immune deficiency less profound than severe combined immuno deficiency' (52%), chronic granulomatous disease (66.6%), and X-linked agammaglobulinemia (50%) patients. Severe malnutrition was present in 22 (21.2%) of the patients, although it was not significant. It was more common in the phagocytic system disorder group. All patients in the severe combined immunodeficiency group had undergone hematopoietic stem cell transplantation and 50% of them had malnutrition. There was also no significant difference regarding age, sex, anthropometric indexes (Weight for age, lenght/height for age body mass index Z-scores), malnutrition types, and prevalence of malnutrition among three major disease groups. Only the hospitalization history inversely related to body mass index and weight for age Z-scores (P < 0.0001). In patients with malnutrition, daily caloric intake was at least 20% or more below the requirement. CONCLUSIONS: Regardless of the type of immunodeficiency, nutritional status was poor in PID and hospitalization is the most important determinant of nutritional status. Even after hematopoietic stem cell transplantation, nutritional support should be continued.

Endocrine disruptors have been proposed in the etiology of polycystic ovary syndrome (PCOS) as they have the potency to interfere with hormone-sensitivity systems. The aim of this study was to evaluate the levels of bisphenol A (BPA) and phtalates in adolescents with PCOS. Sixty-two girls with PCOS and 33 controls, age 12-18 years were enrolled in the study. The diagnosis of PCOS was made using modified Rotterdam criteria. Urinary BPA levels were measured using high-performance liquid chromatography. Di-(2-ethylhexyl)-phthalate (DEHP), the most commonly used phthalate and mono-(2-ethylhexyl)-phthalate (MEHP), its main metabolite were measured by using high-performance liquid chromatography. Adolescents with PCOS had markedly increased BPA levels (15.89 µg/g creatine ± 1.16) when compared with the control group (7.30 µg/g creatine ± 1.38) (p = .016). In adolescents with PCOS, BPA was significantly correlated with polycystic morphology on ultrasound but not with obesity androgen levels, or other metabolic parameters. Patients with PCOS (DEHP: 0.40 ppm ± 0.24, MEHP: 0.13 ppm ± 0.23) and controls (DEHP: 0.49 ppm ± 0.27, MEHP: 0.14 ppm ± 0.3) had similar serum phtalate concentrations (p = .7 and p = .3, respectively). Exposure to specific endocrine disruptors such as BPA could modify neuroendocrine, reproductive, and metabolic regulation favoring PCOS development in adolescents.

BACKGROUND: This study evaluated cardiac function using tissue Doppler echocardiography and assessed electrocardiographic findings in children diagnosed with Wilson's disease. METHOD: Asymptomatic patients with a diagnosis of Wilson's disease (n = 43) were compared to healthy controls (n = 37) that were age and gender matched. RESULTS: The standard electrocardiographic and conventional echocardiographic examinations were similar in both groups. The left ventricular ejection fraction, shortening fraction, and diastolic function were not significantly different between the two groups. The Tei index for mitral lateral, mitral septal, tricuspid lateral, tricuspid septal, and inter-ventricular septum on tissue Doppler echocardiography was higher in the patient group, yet it did not reach statistical significance. Mitral lateral and septal systolic annular velocity values were significantly lower in the patient group when compared to the control group (p = 0.02 and 0.04, respectively). Also, mitral lateral and septal isovolumetric contraction time values were higher in the patient group (p = 0.04). Although the left ventricular values were not significantly different, relative left ventricular wall thickness was higher in the patient group when compared to the control group, and concentric remodelling in the left ventricle was found in 7 (16%) of 42 patients. QT interval (p = 0.02) and P-wave dispersion values (p = 0.04) were significantly higher in the patient group compared to the control group, and these tend to predict arrhythmias. CONCLUSION: Our study based on the tissue Doppler echocardiography assessment indicated a subclinical systolic, rather than diastolic, dysfunction in the myocardium with increased QT interval and P-wave dispersion, despite the young age of the patients and short disease duration.

INTRODUCTION: Adenosine deaminase (ADA) deficiency is an autosomal recessive primary immunodeficiency. It results in the intracellular accumulation of toxic metabolites which have effects particularly on lymphocytes and the brain. The aim of this study was to evaluate the outcome of 13 ADA-deficient patients. We planned to evaluate their clinical and laboratory findings before and after enzyme replacement therapy (ERT), allogeneic hematopoietic stem cell transplantation (aHSCT), and hematopoietic stem cell gene therapy (HSCGT). METHODS: Measurement of ADA enzyme activity and metabolites and sequencing of the ADA gene were performed in most of the patients with ADA deficiency. One of the patients with late-onset ADA deficiency was diagnosed by the help of primary immunodeficiency panel screening. RESULTS: Ten out of 13 patients were diagnosed as SCID, while 3 out of 13 were diagnosed as delayed-/late-onset ADA deficiency. Late-onset ADA deficiency patients had clinical and laboratory findings of combined immunodeficiency (CID). Eight patients with ADA-SCID were found to have higher levels of ADA metabolite (dAXP%) (62.1% (34.6-71.9)) than 3 patients with delayed-/late-onset ADA deficiency (6.9% (2.1-8.9). All but one patient with SCID had T-B-NK- phenotype, one had T-B-NK+ phenotype. Genetic defect was documented in 11 patients. Four out of 11 patients had compound heterozygous defects. Three out of 4 patients with compound heterozygous defects had delayed-onset/late-onset ADA deficiency. Seven out of 11 patients with SCID had homozygous defects. Five out of 7 had the same homozygous indel frameshift mutation (c.955-959delGAAGA) showing a founder effect. There were two novel splice site defects: one (IVS10+2T>C) was heterozygous in a patient with late-onset ADA deficiency, and the other was homozygous (IVS2delT+2) in a SCID patient. Other defects were missense defects. Nine out of 13 patients were put on pegylated ADA ERT. Four out of six patients were transplanted without using a conditioning regimen. HSCGT was performed to one of the patients. CONCLUSION: The genetic diagnosis of SCID is utmost important. There is a chance to give ERT before the definitive therapy if the patient with SCID/CID has ADA deficiency. Although ERT was insufficient to restore a normal immune function in ADA-SCID patients, it was useful to improve and stabilize the clinical status before curative therapy (aHSCT/HSCGT). Enzyme replacement therapy was successful in patients with late-/delayed-onset ADA deficiency who presented with the features of combined immunodeficiency. Gastrointestinal polyposis in a patient with late-onset ADA deficiency may be an association or a coincidental finding. Intermittent neurodevelopmental evaluation especially for hearing impairment should be performed in most of the ADA-deficient patients. This may alleviate the speech delay and cognitive abnormalities which may be observed in the follow-up.

The use of extended criteria donors who might have previously been deemed unsuitable is an option to increase the organ supply for transplantation. This report presents a pediatric case of a successful liver transplantation from a donor with ß-thalassemia intermedia. A patient, 6-year-old female, with a diagnosis of cryptogenic liver cirrhosis underwent deceased donor liver transplantation from a thalassemic donor. Extreme hyperferritinemia was detected shortly after transplantation. The most probable cause of hyperferritinemia was iron overload secondary to transplantation of a hemosiderotic liver. Hepatocellular injury due to acute graft rejection might have contributed to elevated ferritin levels by causing release of stored iron from the hemosiderotic liver graft. Iron chelation and phlebotomy therapies were started simultaneously in the early postoperative period to avoid iron-related organ toxicity and transplant failure. Follow-up with monthly phlebotomies after discharge yielded a favorable outcome with normal transplant functions. Thalassemia intermedia patients can be candidates of liver donors to decrease pretransplant waitlist mortality. After transplantation of a hemosiderotic liver, it is important to monitor the recipient in terms of iron overload and toxicity. Early attempts to lower iron burden including chelation therapy and/or phlebotomy should be considered to avoid organ toxicity and transplant failure.

Niemann-Pick disease type C (NPC) is a neurovisceral lysosomal storage disorder with a great variation in clinical spectrum and age at presentation. Clinical features of 10 NPC patients who presented in the newborn period between 1993 and 2015 at our center were retrospectively analyzed. Males and females were equally distributed; there was a history of parental consanguinity (n = 8) and first-degree relative with NPC (n = 3). Patients were symptomatic between 1 and 10 days (mean 3.6 ± 2.6 days). Age at diagnosis was between 1 and 30 days (mean 14.6 ± 13.3 days). Laboratory work-up included bone marrow aspiration (n = 8) and/or filipin staining (n = 4). Confirmation was done by molecular analysis, indicating NPC1 (n = 8) and NPC2 (n = 2) mutations. All patients had neonatal cholestasis and hepatosplenomegaly. Pulmonary involvement (n = 9) and fetal ascites (n = 2) were additional accompanying features. All but one died due to pulmonary complications (n = 6) and liver insufficiency (n = 3) between 1.5 and 36 months of age (mean 8.1 ± 10.8 months). Currently, one patient is alive at the age of 11 months without any neurological deficit. CONCLUSIONS: Neonatal presentation is a rare form of NPC with exclusively visceral involvement in the newborn period and poor prognosis leading to premature death due to pulmonary complications and liver failure. What is known: ⢠Neonatal presentation is a rare form of NPC with exclusively visceral involvement in the newborn period and poor prognosis leading to premature death. ⢠Progressive liver disease is the most common cause of death among neonatal-onset NPC patients. What is new: ⢠Natural course of neonatal-onset NPC may show variations. ⢠Pulmonary involvement should be considered as an important cause of death in neonatal-onset cases, and appropriate precautions should be taken to prevent complications of respiratory insufficiency and airway infections.

Glycogen storage diseases (GSDs), also referred to as glycogenoses, are inherited metabolic disorders of glycogen metabolism caused by deficiency of enzymes or transporters involved in the synthesis or degradation of glycogen leading to aberrant storage and/or utilization. The overall estimated GSD incidence is 1 case per 20000-43000 live births. There are over 20 types of GSD including the subtypes. This heterogeneous group of rare diseases represents inborn errors of carbohydrate metabolism and are classified based on the deficient enzyme and affected tissues. GSDs primarily affect liver or muscle or both as glycogen is particularly abundant in these tissues. However, besides liver and skeletal muscle, depending on the affected enzyme and its expression in various tissues, multiorgan involvement including heart, kidney and/or brain may be seen. Although GSDs share similar clinical features to some extent, there is a wide spectrum of clinical phenotypes. Currently, the goal of treatment is to maintain glucose homeostasis by dietary management and the use of uncooked cornstarch. In addition to nutritional interventions, pharmacological treatment, physical and supportive therapies, enzyme replacement therapy (ERT) and organ transplantation are other treatment approaches for both disease manifestations and long-term complications. The lack of a specific therapy for GSDs has prompted efforts to develop new treatment strategies like gene therapy. Since early diagnosis and aggressive treatment are related to better prognosis, physicians should be aware of these conditions and include GSDs in the differential diagnosis of patients with relevant manifestations including fasting hypoglycemia, hepatomegaly, hypertransaminasemia, hyperlipidemia, exercise intolerance, muscle cramps/pain, rhabdomyolysis, and muscle weakness. Here, we aim to provide a comprehensive review of GSDs. This review provides general characteristics of all types of GSDs with a focus on those with liver involvement.

OBJECTIVE: The prevalence of acute pancreatitis and acute recurrent pancreatitis in children has increased over the years, and there are limited data about imaging findings. This study aimed to reveal the imaging findings of acute pancreatitis and acute recurrent pancreatitis in children at a tertiary care hospital. MATERIALS AND METHODS: The patients with acute pancreatitis and acute recurrent pancreatitis diagnosed between January 2007 and December 2018 were included. Demographic and clinical features, follow-up period, and interventions were noted. Imaging features were evaluated for pancreatic enlargement, peripancreatic fluid, and biliary ducts for initial examination and pancreas parenchymal necrosis, peripancreatic collection, walled-off necrosis, pseudocyst, parenchymal atrophy, and biliary ductal dilatation for follow-up. RESULTS: The study included 74 patients with a mean age of 9 ± 4.9 years. The most common causes of acute pancreatitis and acute recurrent pancreatitis were biliary tract anomalies (n = 21), biliary ductal stones (n = 9), and cystic fibrosis (n = 8). Findings consistent with acute pancreatitis were determined by ultrasound in 40.5% (n = 30/74), whereas by magnetic resonance imaging in 60% (n = 39/65). Forty-one percent of the patients (n = 16) with positive magnetic resonance imaging findings did not show any findings on ultrasound. Acute recurrent pancreatitis was seen in 32 patients (43.2%). Follow-up imaging was performed in 55 patients (74.3%) between 2 months and 11 years. At follow-up, 8 patients had peripancreatic collections (6 walled-off necrosis and 2 pseudocysts). CONCLUSION: Recognizing the imaging findings of acute pancreatitis and its complications is crucial. Magnetic resonance imaging should be preferred as a second option following ultrasound, with the advantages of biliary ductal system delineation and better characterization of complications.
RESUMO
PURPOSE: Lansoprazole, a cytochrome P450 2C19 (CYP2C19) substrate, has been widely used in children to manage acid-related diseases. CYP2C19 exhibits marked genetic polymorphisms, and distribution of these polymorphisms varies among different ethnic groups. There is limited data regarding the use of probe drugs for determining CYP2C19 activity in children. The aim of this study was to evaluate lansoprazole as an in vivo phenotyping probe for assessing CYP2C19 activity in children. METHODS: The CYP2C19*2, *3, and *17 variants were determined in 244 children. Three hours after a single oral dose of lansoprazole (n = 94) or omeprazole (n = 19), plasma lansoprazole and 5-hydroxy lansoprazole or omeprazole and 5-hydroxy omeprazole concentrations were analyzed by high-performance liquid chromatography. RESULTS: The CYP2C19*17 was the most frequent variant allele (24.4%). The group of patients with CYP2C19*17*17 genotype had a 70% lower (p < 0.05) mean lansoprazole plasma concentration compared with the CYP2C19*1*1 genotype group, whereas the CYP2C19*2*2 group had 6.9-fold higher (p < 0.01) mean lansoprazole plasma concentration. Lansoprazole metabolic ratios (lansoprazole/5-hydroxy-lansoprazole) were found to be significantly lower in the *17*17 [mean ± standard deviation (SD); 2.8 ± 2.1] group and higher in the *2*2 group (63.5 ± 12.2) compared with that of the *1*1 genotype group (6.1 ± 4.5). CONCLUSION: According to our results from a Turkish pediatric population, lansoprazole is a suitable probe drug for phenotyping CYP2C19. The CYP2C19*2 and *17 variants should be taken into consideration in predicting the clinical outcome of therapy with lansoprazole in the pediatric population.

Hepatoblastoma is the most common primary liver cancer of childhood, accounting for two-thirds of primary malignant hepatic neoplasms. Radical surgical removal combined with efficient chemotherapy is essential for cure. Despite a complete tumor resection, hepatoblastoma may recur as isolated local disease. Intrahepatic recurrence of hepatoblastoma after liver resection is among the indications for liver transplant. Here, we present a patient who underwent salvage liver transplant for the treatment of local recurrence of hepatoblastoma. A 13-year-old boy who was diagnosed with hepatocellular carcinoma arising from the left liver lobe and who had been treated with surgical resection was admitted to our outpatient oncology clinic for further evaluation because alpha-fetoprotein levels had started to increase after surgery. Histopathological reexamination of hemihepatectomy material showed a histological aspect of an epithelial hepatoblastoma. Magnetic resonance imaging revealed multifocal lesions in the right liver lobe compatible with local recurrence. Despite a favorable initial response to chemotherapy, the tumor showed progression with increased alpha-fetoprotein levels. The patient was deemed a viable candidate for an urgent liver transplant and underwent right lobe living donor liver transplant. He had excellent graft function without any complications or signs of malignancy in the last follow-up visit at 7 months posttransplant. Salvage liver transplant is a lifesaving and sometimes the only treatment option for patients with local recurrence of hepatoblastoma. Although transplant in the salvage setting has been associated with worse outcomes than primary transplant, recent data have indicated more favorable and acceptable outcomes. Further studies are warranted to better understand the role of salvage liver transplant in the treatment of hepatoblastoma. Early consultation with the liver transplant team is critical in children who are most likely to need extreme resection or liver transplant.

Immunosuppressive therapy is a double-edged sword and causes a risk for some complications, such as opportunistic infections and posttransplant lymphoproliferative disease. The most likely risk factors for posttransplant lymphoproliferative disease are Epstein-Barr virus serology mismatch, prolonged and high viral load for Epstein-Barr virus, higher doses of immunosuppressive therapy, and cytomegalovirus infection. Transplant recipients who are seropositive for Epstein-Barr virus show a lower risk for posttransplant lymphoproliferative disease than seronegative recipients. Here, we present a 3.5-year-old boy who was seropositive for Epstein-Barr virus and developed posttransplant lymphoproliferative disease 18 months after liver transplant with a previous history of cytomegalovirus- related pneumatosis intestinalis.

BACKGROUND: Dietary modifications may have role in prevention and treatment of functional constipation. Macronutrient, extrafluid, and fiber intake have been evaluated and the results are conflicting. The aim of our study was to define the nutritional features associated with functional constipation aged 4 years and older. METHODS: This is a cross-sectional descriptive study. Forty-one patients with functional constipation and 55 age-gender matched controls between 4-18 years old were enrolled. Demographic data, duration of breast-feeding, defecation pattern in the first year of life, physical activity, socioeconomic parameters, and anthropometric measurements were noted. Mean daily macronutrient and micronutrient consumption from the 5-day dietary records were calculated by Nutrition Information System - BEBIS 7.2 version. RESULTS: There were no differences between two groups in energy, water, protein, and fiber consumption. However, in 4-7 years old constipated female and male group, the percentage of carbohydrate was higher (P=0.010, P=0.049, respectively) but fat was lower (P=0.011, P=0.032, respectively). All patients except 4-7 years old boys of both groups got less energy than the reference values. The mean daily protein intake was higher than required in the 4-7 years old constipated and control groups. There was no significant difference in fiber consumption between 2 groups. Breastfeeding >18 months was more common in controls (P=0.039). The constipated group used the squatting toilet more frequently (P=0.002). Lower family income (P<0.001) and parental education levels (P<0.001) were associated with FC. CONCLUSIONS: Dietary habits may be a risk factor for functional constipation, especially, in rapid growth period.

BACKGROUND: To evaluate the cytokine profile in gingival crevicular fluid (GCF) and serum of pediatric inflammatory bowel disease (IBD) patients and determine the cluster patterns of cytokines. METHODS: Fifty IBD patients and 21 systemically healthy children were enrolled in the study. The GCF samples were collected from the participants during periodontal examination and periodontal indices were recorded. Based on activity indexes and response to conventional treatment, patients with IBD were further categorized into subgroups as: remission, active disease, and treatment-resistant. Serum samples were obtained from IBD patients to determine serum levels of cytokines. The levels of pro- (interleukin (IL)-1ß, IL-12, IL-21, IL-22, IL-23, IL-17A, IL-17F) and anti-inflammatory (IL-4, IL-10) cytokines in serum and GCF were measured using Enzyme-linked Immunosorbent Assay (ELISA) kits. RESULTS: Among 50 IBD patients, 58% were in remission, 20% had active disease, and 22% were defined as treatment-resistant. The severity of gingival inflammation measured by the criteria of Löe had increasing trends in IBD patients with active disease and treatment resistance. GCF IL-1ß level was lower and GCF IL-4 and GCF IL-23 levels were higher in IBD patients compared to healthy controls. In the active disease group, more cytokine clusters occurred compared to the control group and other IBD subgroups, as explained by increased cytokine-cytokine interactions. CONCLUSIONS: Considering the increased complexity of cytokine interactions and the increased severity of gingival inflammation in patients with active disease, it can be concluded that disease activity might have an impact on gingival inflammation in pediatric patients with IBD.

BACKGROUND: Mesenteric lymphadenopathy is a rare manifestation of Gaucher disease (GD) in children and can be accompanied by protein losing enteropathy (PLE). PLE is a difficult-to-treat complication of GD. To date, only a few pediatric GD cases with PLE and massive mesenteric lymphadenopathies have been reported. CASE: Here, we report a girl with chronic neuronopathic GD, whose disease course was complicated by massive mesenteric lymphadenopathies with resultant protein losing enteropathy despite a regular and appropriate enzyme replacement therapy of 60 IU/kg/biweekly until the development of mesenteric lymphadenopathies and 120 IU/kg/biweekly thereafter. CONCLUSIONS: PLE is a devastating and life threatening complication of GD developing despite long term use of high dose ERT. Clinicians should be alert for this complication particularly in GD patients presenting with progressive abdominal distension, edema, ascites and diarrhea or in patients who have already developed mesenteric lymphadenopathies. Timely diagnosis may allow early intervention with previously suggested surgical or medical treatment options. Although there is no specific and effective treatment, surgical and aggressive medical interventions in addition to ERT were reported to relieve diarrhea and halt progression of mesenteric lymphadenopathies.

Data from 38 children were retrospectively analyzed to determine the patient characteristics of Turkish children with Gaucher disease (GD) and evaluate the impact of enzyme replacement therapy (ERT) in a pediatric cohort consisting of two different sub-types of the disease, Gaucher disease type 1 (GD1) and type 3 (GD3). Both types were represented equally (GD1/GD3 = 20/18). L444P (35.5%) was the most common mutant allele while L444P/L444P (34.2%) was the most common genotype overall. Compound heterozygosity of N370S and L444P homozygosity were the dominant genotypes in Turkish children with GD1 and GD3, respectively. None of the patients had moderate to severe thrombocytopenia at last follow-up while the percent of patients with anemia decreased from 60% to 5.7% (p < 0.001). Significant improvements in mean liver (from 2.2 to 1.6 MN, p < 0.001) and spleen (from 15.5 to 7.6 MN, p < 0.001) volumes were observed in the first year of ERT. Linear growth was ameliorated as shown by the decrease in the percent of patients having short stature from 34.3% to 13.3% (p < 0.01) at year 5. Erlenmeyer flask deformity, osteopenia and scoliosis were common skeletal findings. Although none of the patients had lung disease at diagnosis, 20% developed radiological findings suggestive of pulmonary involvement. This single center experience is the first comprehensive study from Turkey not only reporting clinical and genetic characteristics of GD patients but also providing information on the outcomes of ERT in two different sub-types of GD. Genotypic background of Turkish children with GD is similar to western populations. Although visceral and hematological therapeutic goals are reached as early as one year of ERT in both sub-types, achieving normal growth takes several more years than suggested in significant number of children with GD.

PURPOSE: The incidence of hepatic steatosis among children has been increasing; however, data distinguishing simple steatosis from a more complex disorder are lacking. METHODS: This study identified the etiologies resulting in hepatic steatosis through a retrospective review of pediatric liver biopsies performed in the last 10 years. A total of 158 patients with hepatic steatosis proven by histopathological evaluation were enrolled in the study, and baseline demographic features, anthropometric measurements, physical examination findings, laboratory data, ultrasonographic findings, and liver histopathologies were noted. RESULTS: The two most common diagnoses were inborn errors of metabolism (IEM) (52.5%) and nonalcoholic fatty liver disease/steatohepatitis (NAFLD/NASH) (29.7%). The three most common diseases in the IEM group were glycogen storage disorders, Wilson's disease, and mitochondrial disease. The rates of consanguineous marriage (75.6%; odds ratio [OR], 26.040) and positive family history (26.5%; OR, 8.115) were significantly higher (p=0.002, p<0.001, respectively) in the IEM group than those in the NAFLD/NASH group. Younger age (p=0.001), normal anthropometric measurements (p=0.03), increased aspartate aminotransferase levels (p<0.001), triglyceride levels (p=0.001), and cholestatic biochemical parameters with disrupted liver function tests, as well as severe liver destruction of hepatic architecture, cholestasis, fibrosis, and nodule formation, were also common in the IEM group. CONCLUSION: Parents with consanguinity and positive family history, together with clinical and biochemical findings, may provide a high index of suspicion for IEM to distinguish primary steatosis from the consequence of a more complex disorder.
RESUMO
BACKGROUND AND STUDY AIMS: Wilson's disease (WD) is a complex disorder related to copper metabolism and neurological involvement may lead to swallowing disorders. The purpose of this study was to evaluate swallowing function in pediatric patients with WD by using videofluoroscopic swallowing study (VFSS). PATIENTS AND METHODS: A total of 21 patients were included in the study, prospectively. The VFSS was conducted to evaluate swallowing function of the patients. The penetration-aspiration scale (PAS) was used to assess penetration-aspiration severity. RESULTS: According to the VFSS, abnormal results were detected in nine patients (42.9%) with WD. Of these nine patients, oral phase dysfunction was present in one patient, laryngeal penetration was present in one patient and moreover, abnormal esophageal body function was detected in all nine patients. Of these nine patients, five had neurological presentation at the time of diagnosis, and remaining four patients had hepatic presentation. Mean PAS score of the patients was 1. CONCLUSION: The current study results suggest that subclinical swallowing dysfunction may be observed in patients with either neurological or hepatic WD. Further studies are necessary to reveal the real incidence of esophageal phase problems of swallowing function in pediatric patients with WD.
