Pathogenic variants in polymerase-I and transcript release factor gene (PTRF), or CAVIN1, is responsible for CGL4. In addition to generalized fat loss, patients with CGL4 were reported to suffer from myopathy, malignant cardiac arrhythmias, gastrointestinal disorders, and skeletal abnormalities. Here we describe the phenotype of a child with CGL4 due to a rare, novel pathogenic variant in the PTRF/CAVIN1 gene and the long-term effects of metreleptin substitution on comorbidities. Case presentation We describe a now 20-year-old female patient. At the age of 14-years, she was referred to the University Clinic because of uncontrolled diabetes with an HbA1c of 9.3%, requiring 2.4 IU insulin/kg total-body-weight to normalize blood glucose, hepatomegaly, and hypertriglyceridemia of 515 mg/dL. Additionally, she was suffering from malignant cardiac arrhythmia, myopathy, and hyperCKemia. In light of these clinical findings, she was diagnosed with CGL due to a rare, novel variant in the PTRF gene, and was started on metreleptin, a synthetic analog of human leptin. After the initiation of metreleptin treatment, insulin therapy could be stopped and improvement of sonographically assessed liver size was observed, even though serum liver function test stayed mildly elevated. Furthermore, a noticeable improvement of the serum triglyceride levels was also seen. Medical care and regular follow-up visits are being carried out by a multi-disciplinary team. Conclusions Although CGL4 is rare, due to its life-threatening comorbidities and the opportunity for an early intervention, it is important that the clinicians should recognise these patients.","PeriodicalId":16746,"journal":{"name":"Journal of Pediatric Endocrinology and Metabolism","volume":"208 0 1","pages":"946 - 952"},"PeriodicalIF":0.0,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84839321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It comprises a heterogeneous group of primary, secondary and acquired disorders. Presentation differs according to the child’s age, but it usually presents with nonspecific and insidious symptoms and signs. The main purpose of this study was to describe and compare patients with primary or secondary AI. Methods Retrospective analysis of all patients with adrenal insufficiency followed at the Pediatric Endocrinology Unit in a tertiary care Portuguese hospital over the last 30 years. Data on family history, age at the first manifestation and at etiological diagnosis, and clinical presentation (symptoms, signs and laboratory evaluation) was gathered for all patients. Results Twenty-eight patients with AI were included; 67.9% were male, with a median (25th–75th percentile, P25–P75) age of 1 (0.5–36) month at the first presentation. The principal diagnostic categories were panhypopituitarism (42.9%) and congenital adrenal hyperplasia (25%). The most frequent manifestations (75%) were vomiting and weight loss. They were followed for a median (P25–P75) period of 3.5 (0.6–15.5) years. In respect to neurodevelopmental delay and learning difficulties, they were more common in the secondary AI group. Conclusions Despite medical advances, the diagnosis and management of AI remains a challenge, particularly in the pediatric population, and clinicians must have a high index of suspicion. An early identification of AI can prevent a potential lethal outcome, which may result from severe cardiovascular and hemodynamic instability.","PeriodicalId":16746,"journal":{"name":"Journal of Pediatric Endocrinology and Metabolism","volume":"31 1","pages":"631 - 638"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85651318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the monogenic types of non-syndromic obesity, melanocortin-4 receptor (MC4R) deficiency is the most frequent cause. Beside pathogenic variants, single-nucleotide polymorphisms in MC4R gene are also associated with lower energy expenditure. The aim of this study was to estimate the frequency of MC4R variants and polymorphisms in a cohort of Turkish children and adolescents with severe early-onset obesity, and to understand the clinical features of patients. Methods Patients, 1–17 years of age, with the onset of obesity before 10 years of age and a body mass index (BMI) standard deviation score (SDS) of >2.3, and who had a family history of early-onset obesity in at least one of their first-degree relatives were included in the study. Beside routine blood tests genetic analyses for MC4R gene were performed. Results Analyses of MC4R revealed previously known variations in three (3.5%) patients, and pathogenic polymorphisms related with obesity in four (4.7%) patients. BMI SDS values were between 2.8 and 5.5 SDS in the pathogenic variant carrier group, and 2.8–4.9 SDS in the polymorphism group. Mean BMI SDS in variant-negative group was 3.4 ± 0.82. Conclusions Investigation of the MC4R in individuals with early-onset obesity and presence of obesity first-degree relatives is important. Hypertension is a rare comorbidity compared to other causes. Contrary to studies reporting that insulin resistance was absent or very rare, we found it as a frequent finding in both pathogenic variants and polymorphisms of MC4R.","PeriodicalId":16746,"journal":{"name":"Journal of Pediatric Endocrinology and Metabolism","volume":"1 1","pages":"657 - 662"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72956265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, an exacerbated psychosocial burden in populations with chronic disease is observed. This cross-sectional study evaluated the psychosocial factors of pediatric type 1 diabetes (T1D) during the COVID-19 pandemic. Methods During April 2020, 15 min phone interviews were performed for pediatric T1D group (n=100) and healthy comparison group (n=93) to assess psychosocial functioning during the acute lockdown phase of the pandemic. The patient health questionnaire-4 was utilized to assess anxiety and depressive symptoms. An additional questionnaire to assess specific concerns related to T1D and COVID-19 was administered to the T1D group to explore potential causes for increased psychosocial burden. Results T1D was associated with a five-times higher risk of anxiety symptoms. Increased anxiety symptoms in T1D group appear to be, at least in part, due to fear of higher risk of severe COVID-19 infection and uncertainty regarding access to diabetes supplies. Conclusions This study provides a snapshot of mental well-being in a diverse population of patients with T1D in the acute phase of a crisis and underscores the need for timely, accurate medical information and distribution of medical resources for pediatric T1D population.","PeriodicalId":16746,"journal":{"name":"Journal of Pediatric Endocrinology and Metabolism","volume":"16 1","pages":"627 - 630"},"PeriodicalIF":0.0,"publicationDate":"2022-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87630446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The severity of the inflammation at the time of diagnosis may affect the occurrence or duration of this phase. We aimed to investigate the relationship between hematological inflammatory parameters at the time of diagnosis in T1DM and (i) daily insulin requirement during the follow-up and (ii) the presence of partial clinical remission period, which was determined according to insulin dose-adjusted HbA1c levels. Methods A single-center retrospective study was conducted, including children who were diagnosed with T1DM, were positive for at least one autoantibody, and were followed up for one year in our clinic between 2010 and 2020. Results Sixty-eight patients (55.9% female, 64.7% prepubertal) were included in the study, whose mean age was 8.4 ± 4.2 years. A total of 38 patients (55.9%) had partial clinical remission. None of the initial hematological indices were associated with the occurrence of partial remission. Initial neutrophil/lymphocyte ratio (NLR) and derived-NLR (d-NLR) levels were significantly lower (p=0.011 and 0.033, respectively) and lymphocyte/monocyte ratio (LMR) levels were significantly higher (p=0.005) in patients who showed an insulin requirement of <0.5 IU/kg/day at the 3rd month after diagnosis. Conclusions Initial hematological parameters were not found as a predictor of partial clinical remission period in T1DM in children. However, a lower NLR and d-NLR, or a higher LMR at the time of diagnosis can be used as an indicator of a low daily insulin need at the 3rd month of T1DM.","PeriodicalId":16746,"journal":{"name":"Journal of Pediatric Endocrinology and Metabolism","volume":"30 1 1","pages":"593 - 602"},"PeriodicalIF":0.0,"publicationDate":"2022-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80476159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Congenital multiple joint contractures with microcephaly, typical facial dysmorphism, developmental delay, strabismus, tremor, and increased tone are the main characteristics defined in seven patients thus far. One third of the individuals with monoallelic mutations of the gene develop isolated early-onset dystonia (DYT1 dystonia), which is inherited in an autosomal dominant fashion, with variable expressivity and incomplete penetrance. We believe that different inheritance patterns of the same gene resulting in different phenotypes will provide an opportunity to understand other similar disease groups and different aspects of gene functions. Case presentation We present a case with severe arthrogryposis multiplex congenita, respiratory failure, and feeding difficulties, with additional hitherto unreported symptoms, such as spontaneous bone fracture, sliding esophageal hernia, and uterine prolapse.
