Evaluation of some predictive parameters for baked-milk tolerance in children with cow's milk allergy.

BACKGROUND: Inclusion of baked-milk products to the diet appears to markedly accelerate tolerance to unheated milk compared to a strict avoidance diet. OBJECTIVE: : The present study aims to investigate the predictors of baked-milk tolerance in children with Immunoglobulin E (IgE)-mediated cow's milk (CM) allergy. METHODS: The study included 80 patients diagnosed with IgE-mediated CM allergy upon oral food challenge (OFC) testing at our clinic. Patients who developed and did not develop reactions during OFC with baked milk were compared considering clinical and laboratory parameters. RESULTS: Eighty patients with CM allergy comprised 48 male and 32 female infants with an average age of 7.25 ± 2.45 (3-13) months. We found that 62.5% of them showed tolerance to baked milk in the OFC test performed with cakes containing 2.6-g milk protein. When the patients who tolerated and could not tolerate baked-milk products were compared for test results, we detected a statistically significant intergroup difference regarding diameter of wheal in skin prick test (SPT) performed with muffin slurry, levels of specific Immunoglobulin E (sIgE) in CM, sheep's milk (SM), goat's milk (GM), casein, and the amount of unheated milk consumed until a reaction developed in the OFC test performed with unheated milk (P < 0.05). CONCLUSION: We defined novel decision points based on CM, SM, GM, casein sIgE levels, wheal diameter in SPT with muffin slurry, and the amount of milk ingested during OFC performed with unheated milk that may be useful in predicting outcomes of baked-milk ingestion.

Distribution of inhalant allergies in pediatric patients presenting with allergic complaints in the Eastern Anatolia Region.

BACKGROUND: The objective of this study was to define the distribution of inhalant allergens in pediatric patients in whom sensitization was diagnosed with a skin prick test (SPT) who had presented with allergic complaints. In addition, the correlation between the inhalant allergens detected on the SPT and the patients' demographic features, diagnosis, and laboratory findings was defined. METHODS: A total of 1415 children among the 4056 patients who presented at a clinic in the Eastern Anatolia region with allergic complaints and who had undergone an SPT were included in this study. RESULTS: On the SPT, sensitization to grass pollens was found in 60.1%, cereals pollens in 57.2%, and Dermatophagoides farinae in 21.8% of the patients. Furthermore, on the SPT, incidence of asthma development was 3.96 times higher (odds ratio 3.96, 95% CI: 1.77-6.83; P=0.001) in patients who were allergic to Dermatophagoides farinae. CONCLUSIONS: In our study, differences were found in the study region compared to data from around the world and other regions in Turkey in terms of the distribution of allergies and variations in allergens in patients diagnosed due to variations in climate and plants.

Assessment of the levels of serum Hsp 70 and ghrelin in children with simple febrile convulsions.

BACKGROUND: In this study we aimed to evaluate the serum levels of Heat-shock protein (Hsp) 70 and acylated and desacylated ghrelin in patients suffering from a simple febrile convulsion. METHODS: This cross-sectional study included patients who were diagnosed with a simple febrile convulsion, afebrile tonic-clonic epileptic seizure and upper respiratory tract infection when admitted to our hospital. All patients were aged between six months and 60 months. Patients enrolled in this study were divided into five groups. Group I: patients with a simple febrile convulsion and body temperature of 38º C to 39° C; group II: patients with a simple febrile convulsion and body temperature of 39.1° C to 41° C; group III: patients with primary generalised tonic-clonic seizure and normal body temperature; group IV: patients with upper respiratory infection without convulsion and a body temperature of 38° C to 39° C; and group V: patients with upper respiratory infection without convulsion and a body temperature of 39.1° C to 41° C. The control group included healthy children who were followed up in the healthy children polyclinic. Serum levels of Hsp70 and acylated and des-acylated ghrelin were studied from the blood samples collected from the patients and control group. RESULTS: Serum levels of Hsp70 were higher in the febrile convulsion (groups I, II) and epileptic convulsion and infection (groups IV, V) groups than in the controls (P<0.0001). Moreover, serum levels of acylated and desacylated ghrelin were higher in the simple febrile convulsion (groups I and II) and epileptic convulsion and infection (groups IV and V) groups than in the control (P<0.05). CONCLUSIONS: We demonstrated that serum levels of Hsp70 and acylated and desacylated ghrelin increased in patients with a simple febrile convulsion.

A family with interleukin-17 receptor A deficiency: a case report and review of the literature.

BACKGROUND: Chronic mucocutaneous candidiasis (CMC) is characterized by recurrent or persistent infections of the skin, nail, oral, and genital mucosa with Candida species, mainly Candida albicans. In a single patient, the first genetic etiology of isolated CMC autosomal recessive interleukin-17 receptor A (IL-17RA) deficiency was reported in 2011. CASE: We report four patients with CMC who displayed autosomal recessive IL-17RA deficiency. The patients were from the same family, and their ages were 11, 13, 36, and 37 years. They all had their first CMC episode by six months of age. All patients manifested staphylococcal skin disease. We documented high IgG levels in the patients. In addition, we found the coexistence of hiatal hernia, hyperthyroidism, and asthma in our patients. CONCLUSIONS: Recent studies have provided new information on the heredity, clinical course, and prognosis of IL-17RA deficiency. However, further studies are needed to reveal the full picture of this congenital disorder.

Evaluation of toll-like receptors 2 and 4 polymorphism and intestinal microbiota in children with food allergies.

BACKGROUND: Mutual regulation between immune system and gut microbiota is achieved through several mechanisms including the engagement of toll-like receptors (TLRs) which is expressed on numerous cell types. In this study we aimed to explore the association between food allergies and TLR gene polymorphisms in association with gut microbiota. METHODS: Toll-like receptors polymorphism frequencies and some bacteria in the gut microbiota in 130 infants aged 1-24 months with egg and/or milk allergy in a prospective cohort were compared with 110 non-food allergic controls. Four candidate polymorphisms (TLR2 rs1898830/rs5743708 and TLR4 rs4986790/rs4986791) were genotyped by allelic discrimination polymerase chain rection (PCR) method. Gut microbiota analysis was achieved by using high-throughput sequencing. RESULTS: The TLR4 rs4986790 (Asp299Gly) single nucleotide polymorphism (SNP) major/minor allele frequency was 0.788/0.212 in food allergy patients and 0.719/0.280 in controls (p=0.017). There was a statistically significant difference between groups in terms of genotype frequencies (AA, AG, GG). Gut microbiota analysis revealed increased Firmicutes phylum in stool of the patients with food allergy. Except for TLR4 rs4986791 (Thr399lle) allele, the other TLR polymorphisms were not associated with food allergies in children. When the bacteria in the intestinal microbiota and TLR2 and TLR4 gene polymorphisms were compared; we determined a statistically significant increase in Bifidobacterium concentration in the intestinal microbiota in TLR4 rs4986791 CT heterozygous genotype (p=0.004). CONCLUSIONS: This study demonstrated a partial role of TLR4 gene polymorphism and gut microbiota in the development of food allergies. Future work in this area will be required to clarify the roles of different microbial strains that modulate gut microbiota composition and function in conjunction with TLR transcription pathways.

Neonatal Resuscitation Practices in Turkey: A Survey of the Turkish Neonatal Society and the Union of European Neonatal and Perinatal Societies.

OBJECTIVE: Optimal care in the delivery room is important to decrease neonatal morbidity and mortality. We aimed to evaluate neonatal resuscitation practices in Turkish centers. MATERIALS AND METHODS: A cross-sectional survey consisted of a 91-item questionnaire focused on delivery room practices in neonatal resuscitation and was sent to 50 Turkish centers. Hospitals with <2500 and those with ≥2500 births/year were compared. RESULTS: In 2018, approximately 240 000 births occurred at participating hospitals with a median of 2630 births/year. Participating hospitals were able to provide nasal continuous-positiveairway-pressure/high-flow nasal cannula, mechanical ventilation, high-frequency oscillatory ventilation, inhaled nitric oxide, and therapeutic hypothermia similarly. Antenatal counseling was routinely performed on parents at 56% of all centers. A resuscitation team was present at 72% of deliveries. Umbilical cord management for both term and preterm infants was similar between centers. The rate of delayed cord clamping was approximately 60% in term and late preterm infants. Thermal management for preterm infants (<32 weeks) was similar. Hospitals had appropriate equipment with similar rates of interventions and management, except conti nuous-positive-airway-pressure and positive-end-expiratory-pressure levels (cmH2O) used in preterm infants (P = .021, and P = .032). Ethical and educational aspects were also similar. CONCLUSIONS: This survey provided information on neonatal resuscitation practices in a sample of hospitals from all regions of Turkey and allowed us to see weaknesses in some fields. Although adherence to the guidelines was high among centers, further implementations are required in the areas of antenatal counseling, cord management, and circulation assessment in the delivery room.

Evaluation of serum/salivary levels of carnosine and cotinine in recurrent wheezing of young children with passive smoking.

BACKGROUND: Recurrent wheezing is common in young children, with a cumulative prevalence of up to 40 % in the first 6 years of life. In this study, we aimed to evaluate the relationship between the number of wheezing episodes and the number of cigarettes smoked at home and serum / saliva cotinine and carnosine levels in children with recurrent wheezing. METHODS: This study was conducted with 80 young children with recurrent wheezing, aged between 1-4 years and 50 healthy control groups. Patient population was divided into three groups depending on the number of their exposure to cigarette smoke and wheezing attacks. Serum cotinine, saliva cotinine, serum carnosine, saliva carnosine, vitamin D levels were measured by using the ELISA method. RESULTS: A significant relationship for serum cotinine and saliva cotinine levels was found between groups (p < 0.05). It was determined that as the number of exposure to cigarette smoke and number of wheezing episodes in young children with recurrent wheezing increased, the level of serum/saliva cotinine levels increased significantly, compared to the control group. In contrast, it was determined that as the number of exposure to cigarette smoke and number of wheezing episodes in young children with recurrent wheezing increased, serum/saliva carnosine levels decreased significantly, compared to the control group. In addition, a significant difference in serum vitamin D levels was found between healthy young children and young children with recurrent wheezing (p < 0.05). CONCLUSIONS: We think that the measurement of salivary cotinine is a useful and noninvasive marker to evaluate passive smoking exposure in the etiology of recurrent wheezing in young children.

Airborne fungal spore relationships with meteorological parameters and skin prick test results in Elazig, Turkey.

BACKGROUND: Since fungi spores have high concentrations in the atmosphere during most of the year, they have an important place in respiratory allergies. In this regard, the preparation of calendars showing fungi spore loads for residential areas has much importance in the treatment of the patients. The first aim of this study was to present the airborne fungal spore research results from Eastern Anatolia in Turkey. Then, the mold spores' relationships with the meteorological parameters and skin prick test results were also evaluated. The presence of fungal spores was investigated using a volumetric spore trap in 2018 year. METHODS: In this study, fungal spores within the atmosphere of the Elazig city of Turkey was measured through the volumetric method, using a Lanzoni VPPS 2000 device (VPPS 2000 Lanzoni, Bologna, Italy), in 2018 year. Annual data of temperature, humidity, precipitation and wind speed were used for comparing meteorological data with airborne fungal spore counts. In addition, 637 children who were admitted to a pediatric allergy clinic with allergic complaints were enrolled in the study. RESULTS: A total of 145,099 spores/m3 and 20 fungal taxa belonging to the molds were recorded. Ustilago was the predominant genus (18.10%), followed by Oidium (18.01%), Drechslera (12.82%), and Fusarium (11.60%), which were the most common fungal spores found in Elazig's atmosphere. The total mold spores in the atmosphere reached the highest level, with 28,153 spores/m3, in July (mid-summer). Moreover, we found a positive correlation between the mold spores and the temperature, but negative correlations with the humidity and wind speed. In the skin prick tests in the children with allergic complaints, we detected sensitization to Alternaria alternata in 4.4%, Cladosporium herbarum in 3.0%, Penicillium notatum in 1.4%, and Aspergillus fumigatus in 1.1%. Additionally, there was no correlation between fungal spore concentration in the atmosphere with fungal spores sensitization in the skin prick test. CONCLUSIONS: This study was the first aerofungal survey of the Eastern Anatolia region in Turkey; therefore, new information has been introduced in the field of aerobiology in Turkey.

The Vitamin D Receptor Gene Polymorphisms in Asthmatic Children: A Case-Control Study.

Background: The association between vitamin D receptor (VDR) polymorphisms and the risk of asthma remains unclear. This study aimed to investigate the effect of VDR gene polymorphisms and VDR mRNA expression levels on respiratory function, nitric oxide levels in expiratory air, and serum vitamin D levels in children with asthma. Materials and Methods: The study included 80 healthy children (control group) and 100 asthmatic children (asthma group) between the age of 5 and 18 years. The VDR genotypes (ApaI, TaqI, and FokI) and VDR mRNA levels were determined in all groups. Results: There was no statistically significant difference in vitamin D levels between the asthma group and the control group (P > 0.05). A significant association was found between both genotype (CC) of the TaqI polymorphism [odds ratio (OR) = 0.2, 95% confidence interval (CI) (0.07-0.5), P = 0.003] and genotype (CA) of ApaI polymorphisms [OR = 0.2, 95% CI (0.07-0.8), P = 0.02], and asthma risk. In addition, when single-nucleotide polymorphism allelic frequencies between asthma and control groups were compared there is no significant association (P > 0.05). When compared to control group, VDR mRNA expression in asthma group decreased in genotypes CC and CA of ApaI and in genotypes TT and TC of TaqI (P < 0.05). Conclusion: The results provide supporting evidence for an association between TaqI and ApaI polymorphisms and asthma susceptibility.

A neonate with homozygous protein C deficiency with a homozygous Arg178Trp mutation.

Homozygous protein C deficiency affects approximately 1/400,000 to 1/1,000,000 live births. Homozygous protein C deficiency is associated with catastrophic and fatal purpura fulminans-like or thrombotic complications and disseminated intravascular coagulation. In the present patient, genetic study revealed Arg178Trp, a mutation found widely in European population; but this is the first case of homozygous Arg178Trp mutation who suffered from catastrophic purpura fulminans phenotype.

Acute peritoneal dialysis in neonatal intensive care unit: An 8-year experience of a referral hospital.

BACKGROUND: The aim of present study was to evaluate the indications, complications and outcomes of acute peritoneal dialysis (APD) in neonates at a referral university hospital during the previous 8 years. METHODS: This retrospective analysis included a total of 52 newborn infants who underwent APD in a neonatal intensive care unit between January 2008 and March 2016. Demographic, clinical, laboratory and microbiological data were extracted from patients' medical files. RESULTS: The primary causes for requiring APD were acute tubular necrosis (n = 36, 69.2%), inborn error of metabolism (n = 10, 19.2%), congenital nephrotic syndrome (n = 2, 3.9%), bilateral polycystic kidney (n = 2, 3.9%), renal agenesis (n = 1, 1.9%), and obstructive uropathy (n = 1, 1.9%). The mean duration of APD was 8.7 ± 15.87 days (range: 1-90 days). Procedural complications were mainly hyperglycemia (n = 16, 47.1%), dialysate leakage (n = 7, 20.6%), peritonitis (n = 3, 8.8%), catheter obstruction (n = 3, 8.8%), bleeding at the time of catheter insertion (n = 2, 5.9%), catheter exit site infection (n = 2, 5.9%), and bowel perforation (n = 1 2.9%). There were 40 deaths (76.9%), mainly due to underlying causes. Ten of the 12 survivors showed full renal recovery, but mild chronic renal failure (n = 1) and proteinuria with hypertension were seen (n = 1) in each of remaining patients. CONCLUSION: Peritoneal dialysis is an effective route of renal replacement therapy in the neonatal period for management of metabolic disturbances as well as renal failure. Although major complications of the procedure are uncommon, these patients still have a high mortality rate due to serious nature of the underlying primary causes.

Neonatal adrenal insufficiency: Turkish Neonatal and Pediatric Endocrinology and Diabetes Societies consensus report.

It is difficult to make a diagnosis of adrenal insufficiency in the newborn, because the clinical findings are not specific and the normal serum cortisol level is far lower compared to children and adults. However, dehydratation, hyperpigmentation, hypoglycemia, hyponatremia, hyperkalemia and metabolic acidosis should suggest the diagnosis of adrenal insufficiency. Hypotension which does not respond to vasopressors should especially be considered a warning. If the adrenocorticotropin hormone level measured simultaneously with a low serum cortisol level is 2-fold higher than the upper normal limit of the reference range, a diagnosis of primary adrenal insufficiency is definite. Even if the serum cortisol level is normal, a diagnosis of relative adrenal insufficiency can be made with clinical findings, if the patient is under heavy stress. The serum cortisol level should be measured using the method of 'high pressure liquid chromatography' or 'LC mass spectrometry'. Adrenal steroid biosynthesis can be evaluated more specifically and sensitively with 'steroid profiling'. Rennin and aldosterone levels may be measured in addition to serum electrolytes for the diagnosis of mineralocorticoid insufficiency. Adrenocorticotropic hormone stimulation test may be used to confirm the diagnosis and elucidate the etiology. In suspicious cases, treatment can be initiated without waiting for the adrenocorticotropic hormone stimulation test. In schock which does not respond to vasopressors, intravenous hydrocortisone at a dose of 50-100 mg/m2 or a glucocorticoid drug at an equivalent dose should be initiated. In maintanence treatment, the physiological secretion rate of hydrocortisone is 6 mg/m2/day (15 mg/m2/day in the newborn). The replacement dose should be adjusted with clinical follow-up and by monitoring growth rate, weight gain and blood pressure. Fludrocortisone (0,1 mg tablet) is given for mineralocorticoid treatment (2x0,5-1 tablets). A higher dose may be needed in the neonatal period and in patients with aldosterone resistance. If hyponatremia persists, oral NACl may be added to treatment. In the long-term follow-up, patients should carry an identification card and the glucocorticoid dose should be increased 3-10-fold in cases of stress.

Neonatal Gastrointestinal Perforations: the 10-Year Experience of a Reference Hospital.

The aim of this study was to present our experiences with, as well as the factors that affect, the treatment and outcome of patients with neonatal gastrointestinal perforations (GIPs). Thirty-eight newborn cases that were operated on for GIP in our hospital's tertiary newborn intensive care unit between January 2005 and December 2015 were retrospectively evaluated. The patients were divided into the two following groups: group 1, perforations related to necrotizing enterocolitis (NEC), and group 2, non-NEC perforations. In total, 38 patients (16 males, 22 females) participated in this study. The perforations were related to NEC in 12 patients (group 1; 31.6 %), and the other 26 patients (group 2; 68.4 %) were classified as non-NEC perforation cases. The incidence of neonatal GIP was 0.53 % in all newborn patients, while the incidence of perforation in NEC cases was 20 %. Of all patients, 25 (65.7 %) were premature. Non-NEC pathologies were the most common cause of GIP (68.4 %) and included stomach perforation related to a nasogastric catheter (n = 5), volvulus (n = 4), intestinal atresia (n = 3), esophageal atresia and tracheoesophageal fistula (n = 2), cystic fibrosis (n = 2), Hirschprung's disease (n = 2), appendicitis (n = 2), congenital stomach anterior wall weakness (n = 1), duplication cyst (n = 1), invagination (n = 1), incarcerated inguinal hernia (n = 1), and idiopathic causes (n = 2). Primary surgical repair was performed in all cases without a conservative approach. The mortality rate related to GIP in newborn cases was 47.3 %. While the mortality rate in group 1 was 66.6 %, it was statistically insignificantly lower in group 2 (38.4 %) (p > 0.05). In group 1, the mortality rate of those with intestinal and colorectal perforations was 45.6 and 20 %, respectively (p > 0.05). Non-NEC pathologies are the most frequent causes of GIP in newborns, and primary surgical repair is the primary treatment choice for neonatal GIP. However, GIP remains one of the most significant causes of mortality in newborns. While the prognosis for neonatal colon perforation is good, that for stomach and jejunoileal perforations is worse.

Segmental myoclonus as the presenting symptom of an acute disseminated encephalomyelitis: a case report.

Segmental myoclonus is described as the involuntary contractions of contiguous muscles innerved by the brain stem or by spinal cord. The underlying causes of segmental myoclonus in children are demyelinating diseases and intrinsic tumors. Here, we report a case who was presented with segmental myoclonus on his left arm and later diagnosed as atypical monosymptomatic presentation of acute disseminated encephalomyelitis (ADEM). The case represents the first in the literature in which ADEM is considered as the possible cause of segmental myoclonus. Our findings demonstrate that: (i) in focal movement disorders such as segmental myoclonus, a careful neuroradiological examination of the neuroanatomical region for the possible presence of organic lesions might be rewarding, (ii) ADEM might be one of the potentially reversible causes of myoclonus.

Serum and hair levels of zinc, selenium, iron, and copper in children with iron-deficiency anemia.

In the present study, the serum and hair levels of zinc, selenium, and copper were determined in children with iron-deficiency anemia (IDA). A total of 52 anemic children aged 1-4 yr constituted the study group. Forty-six healthy children acted as controls. The copper and zinc levels were measured with an atomic absorption spectrophometer. Serum and hair selenium was determined by a spectroflourometric method. The serum zinc and selenium concentrations in the IDA group were found to be significantly lower and serum copper significantly higher than those in the controls (p < 0.05). Lower iron, zinc, and selenium concentrations (p < 0.001) but not copper were found in hair (p > 0.05).

Magnesium-permeable TRPM6 polymorphisms in patients with meningomyelocele.

BACKGROUND: To evaluate whether there is an association between single nucleotide polymorphisms in magnesium-permeable TRPM6 ion channel and development of meningomyelocele (MMC). Therefore, we examined a total of 150 children with MMC, along with age- and gender-matched controls. DNA collected from whole blood was analyzed for the presence of two polymorphisms, rs2274924 (A > G; K1579E; Leu1579Glu) and rs3750425 (G > A; Val1393Ile), in TRPM6. Serum Mg2+ and calcium levels were also examined. RESULTS: A statistically significant difference in the distribution of rs2274924 genotypes (p = 0.049) was observed between the groups. Decreases in the AA genotype, and increases in the AG heterozygous genotype were also detected in the study group. The distribution of polymorphisms in the rs3750425 genotype and alleles was not statistically different between groups. Serum Mg2+ levels were lower in the GG genotype of rs3750425 compared with the GA and AA genotypes (p = 0.003). CONCLUSIONS: A statistically significant difference in rs3750425 genotypes was observed between the patients with MMC and the controls, which corresponded to lower serum Mg2+ concentrations in these patients. Taken together, these results suggest that genetic variations in the Mg2+-permeable TRPM6 ion channel may play a role in the etiopathogenesis of MMC during embryonic development.

Percutaneous peritoneal drainage in isolated neonatal gastric perforation.

A comment on the article by He et al, "Idiopathic neonatal pneumoperitoneum with favorable outcome: A case report and review", published on World Journal of Gastroenterology that reported a case of idiopathic neonatal pneumoperitoneum, possibly due to gastric perforation, with a favorable outcome without surgical intervention.

The evaluation of serum leptin level and other hormonal parameters in children with severe malnutrition.

OBJECTIVES: Protein-energy malnutrition (PEM) is a clinical problem caused by inadequate intake of one or more nutritional elements, and remains as one of the most important health problems in developing countries. The aim of this study is to determine the relationship among leptin concentrations, body weight and concentrations of some serum hormones, e.g., basal GH, IGF-1, basal cortisol and IGF-BP3, in severe malnourished children, and to determine the effects of leptin in malnourished children. DESIGN AND METHODS: The study group consisted of 36 children diagnosed with PEM. Thirty healthy children were enrolled as the control group. After an overnight fast and before initiation of feedings, fasting venous blood samples were obtained from a forearm vein with needle technique for routine tests, and leptin, IGF-1, IGF-BP3, basal GH and cortisol levels were measured. Tests were carried out in the laboratories of the Department of Biochemistry by commercial kits. RESULTS: Serum leptin levels of infants with marasmus and kwashiorkor were significantly lower than that of the controls (2.09 +/- 0.93 and 2.27 +/- 1.01, 6.82 +/- 2.28 ng/ml, respectively, P < 0.001). However, there was no significant difference between serum leptin levels in children with marasmus and those with kwashiorkor (P > 0.05). Serum IGF-1 and IGF-BP3 levels were significantly lower in malnourished children (P < 0.001, both). Also, basal GH and cortisol levels were significantly higher in malnourished children (P < 0.001, both). There was a positive correlation among serum leptin levels and IGF-1 and IGF-BP3 levels and also a negative correlation among serum leptin levels and basal GH and cortisol levels in children diagnosed with marasmus or kwashiorkor and the control group. CONCLUSIONS: The decrease of energy intake and adipose tissue and serum IGF-1 levels in children with PEM may result in decrease of leptin secretion. Decrease in serum leptin levels may initiate food intake by increasing appetite and stimulating the secretion of cortisol and GH that might increase energy expenditure through an autocrine mechanism. Moreover, serum leptin level may be an important signal to reflect the metabolism of children with PEM.

Serum, urine, and saliva levels of ghrelin and obestatin pre- and post-treatment in pediatric epilepsy.

INTRODUCTION: In this study, we aimed to determine the serum, urine, and saliva levels of acyl ghrelin, des-acyl ghrelin, and obestatin in the newly diagnosed idiopathic generalized pediatric epilepsy patients in the pretreatment period and in the third month of valproic acid. MATERIAL AND METHODS: Thirty pre- and post-treatment cases of patients who were diagnosed with idiopathic generalized epilepsy and 30 control patients were included in this study. Serum, saliva, and urine levels of ghrelin were measured in epileptic group and in the control group in the pretreatment period and in the third month of the treatment. RESULTS: There were 14 females and 16 males. Mean age was 8.9 ± 2.5 years. Mean body mass index was 17.2 ± 2.3 in the patients and 16.6 ± 2.0 in the control group, whereas it was 16.8 ± 2.1 in the third month of the therapy (P > 0.05). Pretherapy serum, urine, and saliva levels of acyl ghrelin were 36.45 ± 9.93, 31.78 ± 12.87, and 34.23 ± 11.49 pg/mL, respectively in the patient group. Post-treatment serum, urine, and saliva levels of acyl ghrelin were 51.34 ± 12.01, 48.24 ± 16.76, and 44.90 ± 14.99 pg/mL in the patient group. Pretherapy serum, urine, and saliva levels of des-acyl ghrelin were 419.62 ± 75.63, 370.59 ± 60.11, and 396.28 ± 60.76 pg/mL, respectively in the patient group. Post-therapy serum, urine, and saliva levels of des-acyl ghrelin were 458.61 ± 87.10, 429.92 ± 55.81, and 449.48 ± 74.32 pg/mL, respectively in the patient group. Pretherapy serum, urine, and saliva levels of obestatin were 23.02 ± 3.15, 14.27 ± 4.22, and 29.52 ± 5.39 ng/mL, respectively. Post-therapy serum, urine, and saliva levels of obestatin were 24.30 ± 4.18, 15.27 ± 6.43, and 30.94 ± 7.42 ng/mL, respectively. CONCLUSION: There was a significant increase in the serum, urine, and saliva levels of acyl ghrelin and des-acyl ghrelin without an increase in post-therapy body mass index in idiopathic generalized epilepsy patients.
