RESUMO

BACKGROUND: Obesity seems to be a critical issue nowadays because of its high prevalence and its adverse effects on health. There is some evidence indicating the relationship between obesity and lower serum 25-hydroxyvitamin D [25(OH)D] concentration. The aim of the present study was to examine serum 25(OH)D status of obese and non-obese Iranian children and compare their therapeutic response with identical oral vitamin D3 treatment. METHODS: In a non-randomized clinical trial, serum 25(OH)D level of 45 obese and 45 non-obese Iranian children aged 2-14 years was measured. Those with serum 25(OH)D status <30 ng/ml (73 cases) were treated with one pearl of vitamin D3 (50 000 International Units) once a week for 6 weeks. Serum vitamin D was measured once more 2 weeks after treatment. RESULTS: The frequency of hypovitaminosis D was 43/45 (95.6%) in obese and 30/45 (66.7%) in non-obese children at baseline (p < 0.001). After treatment of 73 cases (43 obese, 30 non-obese), the above percentages were decreased to 24/43 (55.8%) and 1/30 (3.3%), respectively (p < 0.001). CONCLUSION: Our study demonstrated a high frequency of vitamin D deficiency among Iranian children, particularly the obese ones. Moreover, low therapeutic response in the obese group is witnessed.

RESUMO

The Ullrich-Turner syndrome (complete or partial X-chromosome monosomy) has been found to be associated with an increased rate of some extragonadal neoplasms. Sporadic reports of the Turner syndrome with various brain tumors, including few cases of glioblastoma multiforme, have been found in the literature. However, published data are insufficient to establish a definite relationship between these tumors and the Turner syndrome. Herein, a rare case of primary pediatric glioblastoma multiforme in a 7-year-old girl with Turner's syndrome is reported, and various aspects regarding clinical and pathophysiological issues have been discussed. Although Turner's syndrome is not one of the congenital chromosomal abnormalities which demand routine CNS screening, neurological assessment may be of value in those with relevant clinical findings.

RESUMO

Key Clinical Message: Infantile liver failure type 2 is described as repeated attacks of liver dysfunction with remission. This syndrome should be considered in the differential diagnosis of any child with symptoms of recurrent hepatic encephalopathy. Abstract: Infantile liver failure syndrome 2 is described as recurrent attacks of liver dysfunction. ILFS2 should be included in the differential diagnosis of children with frequent and acute liver failure. We present a 2.5-year-old boy with clinical manifestation of acute liver failure. In past, he had two similar attacks.

RESUMO

Background and Objective: Given the growing awareness about the important role of children's age in building bone for a person's life, physicians need to assess bone health in high-risk children for bone density disorders more than before to optimize their bones' density and prevent osteoporosis in future. The aim of this study was to evaluate bone density based on chronological and bone age. Materials and Methods: In this cross-sectional study, 80 Patients who have been referred for bone density to the Osteoporosis Centre of the Children's Medical Centre over a one-year period (spring 98 to spring 99) were studied. Bone density was performed for all patients by using DEXA method. Results: The z-score mean chronological age for the lumbar spine was -0.8± 1.85 years and bone age was -0.58±1.64 years. The z-score mean chronological age for femoral bone was -1.6±1.02 years and bone age was -1.32± 1.4 years. Conclusion: Results showed that in all patients, the difference in the mean Z score of chronological age and bone age of the spine between patients was not significant but for femur was significant. Also, use of corticosteroids leads to significant difference between the two age groups' z-score in femur and spine.

RESUMO

BACKGROUND: Registries are considered valuable data sources for identification of pediatric conditions treated with growth hormone (GH), and their follow-up. Currently, there is no systematic literature review on the scope and characteristics of pediatric GH registries. Therefore, the purpose of this systematic review is to identify worldwide registries reported on pediatric GH treatment and to provide a summary of their main characteristics. CONTENT: Pediatric GH registries were identified through a systematic literature review. The search was performed on all related literature published up to January 30th, 2021. Basic information on pediatric GH registries, their type and scope, purpose, sources of data, target conditions, reported outcomes, and important variables were analyzed and presented. SUMMARY: Twenty two articles, reporting on 20 pediatric GH registries, were included in this review. Industrial funding was the most common funding source. The main target conditions included in the pediatric GH registries were: growth hormone deficiency, Turner syndrome, Prader Willi syndrome, small for gestational age, idiopathic short stature, and chronic renal insufficiency. The main objectives in establishing and running pediatric GH registries were assessing the safety and effectiveness of the treatment, describing the epidemiological aspects of target growth conditions and populations, serving public health surveillance, predicting and measuring treatment outcomes, exploring new and useful aspects of GH treatment, and improving the quality of patient care. OUTLOOK: This systematic review provides a global perspective on pediatric GH registries which can be used as a basis for the design and development of new GH registry systems at both national and international levels.

RESUMO

Objective: This study is designed to investigate the levels of carnitine and acylcarnitines (ACs) in the children with diabetes type 1 compared to the healthy subjects.Methods: Forty-two type 1 diabetic children and healthy subjects were recruited in the study, respectively. In addition to FBS and Hb A1C, free carnitine and ACs in butyl-ester form in the fasting blood samples were assessed by isotope dilution mass spectrometry for all diabetics and controls using the tandem mass spectrometry system.Results: Diabetic patients had a higher level of C, C4, C6, C14, C18:2, and C18:2OH. Females had elevated C14:2 compared to the males. The C18:2 and C18:2OH levels were elevated as the Hb A1C level increased. The C18:2, C14OH were mostly increased in the prediabetic and diabetic patients, respectively.Conclusion: Increased ACs level indicates the increased acyl-CoA intermediates for the fatty acids and amino acids oxidation.

RESUMO

BACKGROUND: It has been hypothesized that puberty onset is disturbed as the children gain more weight. This study aimed to investigate the prevalence and risk factors of the puberty disturbances among children with obesity in Tehran, Iran. METHODS: This study was performed as a cross-sectional study, investigating 168 children with obesity from Tehran, Iran, from March 2018 to February 2019. BMI percentile more than 95% was considered as the inclusion criteria. RESULTS: Seventy-eight (46.4%) of the assessed children were females. The mean weight, height, BMI were 89.65 (±11.01) kg, 169.88 (±8.32) centimeters and 31.13(±3.8) kg/m2, respectively. There was no difference between males and females regarding the early puberty (P=0.098), but delayed puberty was significantly higher among males (P=0.029). Our results indicated higher birth weight is associated with earlier onset of obesity in children (P=0.044). CONCLUSIONS: Our study demonstrated no association between obesity and early puberty in girls; however, boys with obesity had delayed puberty. We also found higher birth weight is associated with earlier onset of obesity, putting light on the importance of preventive interventions.

RESUMO

OBJECTIVE: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED) is a rare autosomal recessive systemic autoimmune disease caused by mutations in the autoimmune regulator (AIRE) gene. Incidence of this genetic disorder is estimated at 1/90,000-200,000 worldwide and 1/6500-9000 in genetically isolated populations such as Iran. Here, we investigated AIRE gene mutations in eight independent Iranian non-Jewish families. METHODS: We sequenced the coding regions of the AIRE gene and documented mutations which were further confirmed in respective parents. RESULTS: In total, 11 cases from 8 independent families were recruited. Mucosal candidiasis, Addison's disease and hypoparathyroidism were the most common clinical manifestations in these patients. One novel homozygous splice acceptor mutation (c.308-1G>C), and one novel heterozygous stop-gain mutation (c.1496delC) combined with a known heterozygous c.232T>C missense mutation were found. Moreover, we observed previously described splice donor (c.1095+2T>A), frameshift (c.967-979del), stop-gain (c.415C>T), and missense (c.62C>T) mutations among the patients. All results were co-segregated in parents. CONCLUSION: Here, we reported two novel mutations in the AIRE gene leading to APECED. Our data could provide insight into the phenotypic and genotypic spectrum of APECED in the non-Jewish Iranian population. These findings, in addition to future functional assays, can elucidate disease-causing mechanisms related to the AIRE gene and assist in genetic counseling and diagnosis.

RESUMO

BACKGROUND: In Congenital Disorder of Glycosylation (CDG) type Ia, homozygous mutations of the PMM2 gene cause phosphomannomutase 2 dysfunction. CASE PRESENTATION: Herein, a 10-month-old girl, is presented with severe hypotonia, along with inappropriately normal mental status and normal facies. High 2-ketoglutaric acid was detected in her urine, therefore, the diagnosis of 2-Ketoglutarate dehydrogenase complex (KDHC) deficiency was made for this patient. A high dose of vitamin B1 was administered because thiamine is considered a co-factor in this inborn error of metabolism. She responded very well to the daily administration of 500 mg/day vitamin B1 and stood up without help 5 months later. She had also experienced a seizure, which responded well to pyridoxine. Then, she grew up into a 3.5-years-old child who could talk and walk normally. Recently, whole-exome sequencing was performed for her, which showed homozygote mutation of PMM2, therefore, the diagnosis was changed from KDHC deficiency to PMM2-CDG. CONCLUSION: Paying attention to the pathophysiology of inborn errors of metabolism is necessary while considering the defective enzyme co-factor, which may help us to find an option for the treatment of such rare diseases.

RESUMO

Premature pubarche (PP) is the appearance of sexual hair in children before puberty. The PP phenotype may attribute to nonclassic congenital adrenal hyperplasia (NC-CAH). In this study, we investigated the role of CYP21A2 gene variants in patients with PP in the Iranian population. Forty patients (13 males and 27 females), clinically diagnosed with PP, were analyzed for molecular testing of CYP21A2 gene variants. Direct sequencing was performed for the samples. Also, gene dosage analysis was performed for the cases. Fourteen patients (35%) had a mutation of p.Gln318X and p.Val281Leu, out of which 10% had regulatory variants. Approximately 10% of the patients were homozygous (NC-CAH). 78.5% (11/14) of patients had trimodular RCCX of which 5 patients had two copies of CYP21A1P pseudogene. The prevalence of p.Val281Leu was higher than p.Gln318X in PP patients. In conclusion, CYP21A2 variant detection has implications in the genetic diagnosis of PP phenotype. The genetic characterization of the CYP21A2 gene is important for characterizing the variable phenotype of carriers and genetic counseling of PP and NC-CAH patients.

RESUMO

Mucopolysaccharidoses (MPS) are a subgroup of lysosomal storage disorders. The underlying mechanism of MPS disorders are deficiency in specific enzymes which leads to accumulation of partially degraded glycosaminoglycans (GAGs) in various tissues. A wide variety of manifestations are reported but musculoskeletal complaints are common among them. In milder forms of MPS, musculoskeletal complaints are presenting symptoms. Delays in diagnosis due to unspecific and mild symptoms is common. Misdiagnosis of MPS as juvenile idiopathic arthritis and other inflammatory arthritis disorders is frequent. Early diagnosis and treatment prevents irreversible cellular damages and is a key factor in efficacy of enzyme replacement therapy. In this study we described two MPS patients with musculoskeletal complaints who were not diagnosed for a period of time. Although musculoskeletal manifestation are common in a variety of clinical conditions, their presence at low ages or co-occurrence of other manifestations (such as cardiac, respiratory, neurologic, etc.) in multiple systems should prompt evaluation of patients for MPS and other metabolic disorders. The rheumatologists' awareness on MPS should be promoted to achieve timely diagnosis and subsequent early treatment.

RESUMO

BACKGROUND: After the onset of type 1 diabetes mellitus (T1DM), preservation of the residual ß-cell function can help good metabolic control. The aim of this study was to evaluate the effect of vitamin D and its receptor gene polymorphisms on residual ß-cells function. METHODS: One hundred and one children with T1DM (new cases) older than 5 years were selected. Vitamin D receptor (VDR) gene polymorphisms, vitamin D (VD), fasting and stimulated C-peptide (FCP and SCP) levels were measured within 1.5 and 4.5 month after the diagnosis of disease. Kruskal-Wallis and Mann-whitney U test were used for comparing the study groups. Generalized estimating equation (GEE) model was used for the estimation of association between VD and VDR gene polymorphisms with FCP and SCP after adjustment for comorbid variables. RESULTS: The most frequent genotypes and alleles in TaqI, FokI, BsmI and ApaI polymorphisms were TT (50%) and allele T (68.88%), FF (59.2%) and allele F (77.04%), Bb (41.8%) and allele b (61.73%), and Aa (53.1%) and allele A (63.29%) respectively. In children with higher VD levels, the C-peptide (CP) levels were elevated. Also we observed: the tt genotype associated with increasing SCP levels compared with TT genotype; the bb and Bb genotypes were associated with increasing both FCP and SCP in comparison to BB; and the aa and Aa genotypes were associated with decreasing FCP in comparison to the AA genotype. CONCLUSIONS: Sufficient levels of VD (more than 30 ng/ml) can preserve residual ß-cells and insulin secretion.

RESUMO

We performed this study to evaluate the associations of hypothyroidism with clinical severity and the occurrence of diabetic ketoacidosis (DKA) at initial diagnosis among pediatric patients with type 1 diabetes mellitus (T1DM). 330 children with T1DM who referred to Diabetes Clinic were enrolled. The medical records were e valuated and a blood sample was drawn from patients for measuring thyroid function and antibodies, blood glucose, and glycated hemoglobin (HbA1C) levels. Hypothyroidism was detected in 9.6% of children with T1DM and was associated with higher rates of DKA (OR = 3.15, 95%CI = 1.48-6.71) and younger age at initial diagnosis (7.3 ± 3.2 vs. 10.1 ± 2.5, p = 0.04), higher levels of HbA1C upon enrolment (9.8 ± 2.2 vs. 8.8 ± 1.9, p = 0.02) and the requirement for higher insulin doses to control the disease (0.9 ± 0.42 vs. 0.81 ± 0.2, p = 0.03) compared to children with T1DM and normal thyroid function. Additionally children with T1DM and hypothyroidism had significantly higher rates of anti-TPO antibodies (p < 0.001), consanguinity in their parents (p =0.01), and family history of diabetes mellitus (p = 0.02) in their first degree relatives. In conclusion autoimmune hypothyroidism is prevalent among children with T1DM and is associated with a more aggressive disease at initial presentation, poorly controlled T1DM, and requirement for higher Insulin doses for controlling the disease.

RESUMO

INTRODUCTION: Recognition of Acanthosis nigricans (AN) provides important opportunities for screening of obesity syndrome, dyslipidemia, hypertension and insulin resistance with diabetes mellitus 2. Considering the high prevalence of obesity among Iranian children, we designed this study to estimate the prevalence of AN and related laboratory factors in Iranian obese children. MATERIALS AND METHODS: Seventy-one obese children were enrolled in this study. Diagnosis of AN was done by clinical examination. Body mass index (BMI), fasting blood sugar, total cholesterol, triglycerides (TG), alanine aminotransferase, aspartate aminotransferase (AST), alkaline phosphatase, high- and low-density lipoprotein cholesterol, insulin, thyroid-stimulating hormone, free thyroxin (fT4), calcium, phosphorus and 25-hydroxyvitamin D were measured with routine techniques. Collected data were compared between cases with AN and without AN. Independent t-test was used for comparison of variables. RESULTS: Twenty-five of children were female (35.2%). Forty-eight children (67.6%) had AN. In 20 cases (28.2%), homeostasis model assessment-insulin resistance (HOMA-IR) was <2.5 and in 51 (71.8%), HOMA-IR was more than 2.5. Mean BMI, insulin, HOMA-IR, TG and AST levels were significantly higher in cases with AN. CONCLUSION: Obese children with AN are at risk of developing diabetes. Hence early identification of this feature and precise evaluation of children is recommended.

RESUMO

INTRODUCTION: The strict control of blood glucose levels in adolescents with Type 1 Diabetes Mellitus (T1DM) is accompanied with a considerable long term decrease in microvasular and macrovascular complications. AIM: This study was conducted to investigate the effect of metformin as an adjunct therapy in adolescents with poorly controlled Type 1 diabetes. MATERIALS AND METHODS: It was a quasi-experimental (an uncontrolled before and after) study. The study population consisted of the patients aged over 10 years with T1DM. Metformin tablet was added to patient's insulin therapy for 12 months. Haemoglobin A1c protein was measured in the beginning of the study and repeated with three months intervals till the end of it. Insulin dosage, Body Mass Index (BMI), serum lipid, creatinine and lactate level were measured twice; in the beginning of the study and at the end of it (after 12 months). Data was analysed by SPSS (version 18) software. Paired- t-test, Wilcoxon signed ranks test and Repeated Measure ANOVA were used to examine the study's hypothesis. A p-value <0.05 was considered as significant. RESULTS: Twenty nine patients were included in the study. HbA1c level and insulin dosage was significantly reduced (p<0.001) after one month of metformin as an adjunct therapy. Serum lipid was decreased (p=0.7). Weight (p<0.001) and BMI (p=0.007) were increased. CONCLUSION: Adjunctive metformin therapy reduced HbA1c value and the insulin dosage received in adolescents with T1DM.

RESUMO

OBJECTIVE: One of the main problems facing public health providers and administrators in many countries is ensuring the rational use of high-cost drugs. In this regard, on-going process of medication use evaluation can be considered as a useful tool. In this study, we evaluated certain usage aspects of a highly-cost medication, that is, recombinant growth hormone (GH). METHODS: This cross-sectional study conducted from August 2012 to August 2014. Children receiving GH ± gonadotropin releasing hormone (GnRH) analogs were included in the study. A researcher-designed checklist was developed to evaluate the GH utilization in these patients. Baseline demographic characteristics and background clinical and growth data, as well as any aspects of drug therapy including indications, dosing, monitoring, and discontinuation were collected from the patients' medical records. FINDINGS: Seventy children receiving GH entered the study, of which 23 patients (32.85%) received GH and GnRH analogs simultaneously. At the baseline, 67 children (95.7%) had GH stimulation test, whereas serum insulin-like growth factor-1 (IGF-1) levels were measured in 63 (90%) patients. Sixty-seven patients (95.71%) had thyroid function test, whereas bone age was determined in 68 children (97.14%). The mean ± standard deviation of GH dose for idiopathic short stature, GH deficiency, Turner's syndrome and born small for gestational age in our study was 0.22 ± 0.025 mg/kg/week, 0.23 ± 0.04 mg/kg/week, 0.22 ± 0.015 mg/kg/week, and 0.23 ± 0.02 mg/kg/week, respectively. Height and weight of all patients were followed every 3-6 months, regularly. Thirty patients were treated with GH for at least 1 year, of which thyroid hormones and IGF-1 levels were measured annually in 25 (83.33%) and 26 (86.66%) patients, respectively; while bone age was evaluated in 13 (43.33%) children, annually. GH treatment was discontinued in 15 patients (21.42%), while financial problem was the major reason. CONCLUSION: Diagnostic tests and monitoring of height, weight, IGF-1 level and thyroid function was properly performed in this setting. However, a number of patients with ISS and Turner's syndrome were under-dosed.

RESUMO

BACKGROUND: Primary antibody deficiency (PAD) is the most common group of primary immunodeficiency disorders, resulting from different defects in the development and function of B cell lineage. Common variable immunodeficiency (CVID) and X-linked agammaglobulinemia (XLA) are two of the major types of PADs. Optimal growth and subsequently bone health could potentially compromise due to the interference of several factors in PAD with childhood onset. In the present study, our aim was to evaluate bone mineral density (BMD) of patients with CVID and XLA. METHODS: BMD of 37 CVID and 19 XLA patients was examined. Total BMD was determined by dual-energy X-ray absorptiometry and the calculated scores were compared internally and externally with age-sex matched and ethnic-specific reference. Related factors associated with bone density including immune-related complications, serum calcium, phosphate, total alkaline phosphatase, 25(OH) vitamin D and parathyroid hormone levels were recorded. RESULTS: The median age at the time of study was 20 years among all patients and was not statistically different between CVID and XLA groups and the mean of body mass index (BMI) was 19.4±4.6 kg/cm². Thirty-eight (67.9%) of total patients had normal BMD and 18 (32.1%) patients had a low BMD. BMI was positively correlated with BMD at lumbar spine and femoral neck. The number of low BMD patients in CVID (40.5%) group was more than the XLA (15.8%). CONCLUSION: Beside nutritional, gastrointestinal and infectious complications which are shared in both groups of patients, CVID patients are more prone to alteration of BMD due to association with lymphoproliferative and endocrine diseases. Therefore routine evaluation of bone density and treatment adjustment should be considered in all PAD patients particularly in CVID patients.

RESUMO

BACKGROUND: There is limited data on sexual maturation among girls with intellectual, sensory, or physical disabilities. OBJECTIVES: The present cross-sectional study was conducted to assess the sexual maturation of girls with these disabilities in special schools. METHODS: In this cross-sectional study, we evaluated the onset and progression of sexual maturation in 642 six to 18-year-old girls with intellectual, sensory, or physical disabilities from special schools in Tehran. The participants were selected by multi-stage random sampling. Pubertal stages were assessed by visual inspection and palpation based on the rating scales of Tanner. Stage two (breast budding and pubic hair growth) and stage five were considered the onset and end of puberty, respectively. RESULTS: The mean ages of onset of puberty indicated by breast budding (B2 stage) and by pubic hair growth (P2 stage) were 10.8 ± 1.48 and 10.79 ± 1.64 years, respectively. The process of puberty based on breast budding and pubic hair growth was completed at 15.58 ± 1.85 and 15.59 ± 1.8 years, respectively. The average height at the onset of puberty (stage B2) among participants was 128 ± 28.79 cm and the average weight was 8.31 ± 36.47 kg. CONCLUSIONS: Among our patients, the mean ages of onset of puberty indicated by breast budding (B2 stage) and by pubic hair growth (P2 stage) were 10.8 ± 1.48 and 10.79 ± 1.64 years, respectively. Compared to the data from healthy Iranian girls, our findings indicate that the mean age of pubertal onset among schoolgirls with disabilities is slightly higher than that of their healthy counterparts.

RESUMO

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), also named as autoimmune polyglandular syndrome (APS) type 1, is a rare autosomal recessive disorder caused by mutations in autoimmune regulator (AIRE) gene. It is distinguished by an immune-mediated damage of endocrine tissues, chronic candidiasis, and ectodermal disorder. APECED has been shown to be frequent in some populations including Iranian Jews. Here we report three cases of APECED from two independent Iranian Muslim families. Addison's disease, hypoparathyroidismand mucocutaneous candidiasis were shared clinical manifestations in all patients. Mutational analyses have demonstrated a novel homozygous splice site mutation (c.1095+2T>A) in intron 9 and a previously identified homozygous nonsense mutation (c.415C>T) in exon 3 of patients respectively. Future studies are needed to evaluate the frequency of these variants in Iranian APECED patients which would facilitate genetic counseling as well as prenatal diagnosis.

RESUMO

There is a number of syndromes, associated with proptosis, micrognathia, low-set ear and chest deformity. Herein, we report a 9-year-old female with such phenotype who was presented with a vaginal neuroma. The result of karyotype showed 47XX, with extra marker chromosome 22. Although such a manifestation had not been reported in the literature, it should be considered as a very rare manifestation of the disease.
