Background: Natural killer cells are a type of cytotoxic lymphocyte critical to the innate immune system. NK cells from patients with type 1 diabetes (DM1) have numeric and functional abnormalities. However, little is known about the number of NK cells in healthy siblings of children with DM1.Objective and hypotheses: The aim of the study is to compare the population of NK cells and the correlation between NK cells and beta cells autoantibody in healthy ...

Background: Hypophosphatemic rickets (HR) is a group of rare disorders caused by an excessive renal phosphate wasting. The dominant form of X-linked HR (XLHR) is caused by mutation in PHEX (phosphate-regulating endopeptidase) gene. XLHR phenotype is characterized mainly by rickets, bone deformities, short stature, dental anomalies, hypophosphatemia, low renal phosphate reabsorption, normal serum calcium level, hypocalciuria, normal/low serum level of vitamin D (1,25(O...

Objective and hypotheses: The aim of the study is comparison of the occurrence of islet autoantibodies in healthy siblings of children with T1DM to healthy children from non-diabetic families.Method: Determination of anti-decarboxylase of the glutamic acid antibodies (anti GAD-Ab), anti-protein tyrosine phosphatase (anti IA2), and antibodies against zinc transporter eight (anti ZnT8) in 75 children with T1DM, their siblings – 105, and 77 healthy chi...

Objective: Most children with short stature remain without an etiologic diagnosis after extensive clinical and laboratory evaluation and are classified as idiopathic short stature (ISS). This study aimed to determine the diagnostic yield of a multigene gene analysis in children classified as ISS.Design and Methods: We selected 102 children with ISS and performed the genetic analysis as part of the initial investigation. ...

Introduction: The majority of children with short stature are classified as ISS by the absence of findings that could elucidate the cause of their growth impairment. Several monogenic defects have already been identified in children with ISS, but the candidate gene approach is not feasible when there are no specific findings to guide a specific genetic test.Objective: To evaluate the diagnostic yield of a targeted gene p...

Background: Most experts agree that subclinical hypothyroidism (SH) represents early, mild thyroid failure, however there are controversies about the evolution of SH over time.Objective and hypotheses: The aim of the study was to analyse the dynamics of thyroid dysfunction in children initially referred as patients with SH.Method: During the period January 2010 – January 2015, 258 unselected consecutive SH patients (140 girls)...

Background: Timing of puberty is associated with height, cardiovascular health and cancer risk, with a significant public health impact. Previous studies estimate that 60–80% of variation in the timing of pubertal onset is genetically determined. Self-limited delayed puberty (DP) often segregates in an autosomal dominant pattern, but the underlying genetic background is unknown.Methods: We performed whole exome sequencing in 52 members of 7 families...

Background: It is often difficult to establish whether hyperthyrotropinemia in preterm newborn is a simple physiologic energy sparing phenomenon or a true hypothyroidism requiring replacement treatment.Objective and hypotheses: This study aimed to find in what extent thyroid function in the preterm newborn can be influenced by clinical characteristics and complications.Method: We studied 35 preterm newborn, gestational age (GA) 32....

Background: Hypogonadism is one of the major diagnostic criteria of Prader-Willi syndrome (PWS). A hypogonadotropic hypogonadism is often present as a result of hypothalamic dysfunction (together with other hormonal disorders, such as growth hormone deficiency and hypothyroidism).Presentation: A 8.5-year-old boy with genetically-confirmed PWS (maternal uniparental disomy) presented in our Endocrinology Unit for routinely follow-up. Therapy with rhGH was ...

Background: Marfan syndrome (MFS) is an autosomal dominant disorder of connective tissue. Cardinal features affect cardiovascular system, eyes and skeleton. It is caused by mutations of FBN1 gene, which encodes the extracellular matrix protein fibrillin 1. The improper activation of TGFβ, due to defective fibrillin-1, is the pathophysiological mechanism. The altered modulation leads to overgrowth of long bones (disproportionate stature) and altered bone morphology.<p ...
