Dusatkova Lenka , Potuznikova Kristyna , Zemkova Daniela , Marik Ivo , Rozenkova Klara , Lebl Jan , Pruhova Stepanka , Sumnik Zdenek

Background: Recently, mutations in the highly conserved transactivation domain of MAFB gene have been identified as a cause of multicentric carpo-tarsal osteolysis (MCTO), rare skeletal disorder characterised by extensive bone resorption predominantly of the carpal and tarsal bones and frequently accompanied by progressive renal impairment. The MAFB is a basic leucine zipper transcription factor that is involved in the regulation of osteoclastogenesis and renal develo...

The efficacy and safety of recombinant biosimilar growth hormone treatment in children with GHD and SGA: a Czech retrospective national longitudinal study

Snajderova Marta , Zemkova Daniela , Sumnik Zdenek , Zapletalova Jirina , Pomahacova Renata , Pruhova Stepanka , Cermak Jakub , Sadovska Barbora ,

Objectives: Recombinant growth hormone (rhGH) treatment helps to achieve a final height close to the parental growth potential in children with GH deficiency (GHD) and small for gestational age (SGA). Less is known about efficacy and safety of long term therapy with biosimilar rhGH. The aim of our study is to assess height gain and safety of therapy with biosimilar rhGH (Omnitrope®, Sandoz) in Czech children with GHD and SGA over the first three years of ...

Comparison of Manual and Automated Bone Age Assessment in 1285 Children and Adolescents Aged 5 to 16 Years

Maratova Klara , Zemkova Daniela , Lebl Jan , Soucek Ondrej , Pruhova Stepanka , Kolouskova Stanislava , Snajderova Marta , Krasnicanova Hana , Sumnik Zdenek

Background: Skeletal maturation is the most reliable indicator of biological age in children and adolescents. The evaluation of hand and wrist X-Ray according to Tanner-Whitehouse (TW3) or Greulich-Pyle (GP) are the most commonly used methods for biological age assessment. Automated bone age assessment has recently become increasingly popular, however a large independent study comparing automated and manual evaluation of bone age is still missing. The aim of this study was to ...

Hereditary Turner Syndrome 46,X,rec(X)inv(p21q28) in Six Women and Four Generations: Estimation of Skeletal Effects of GH Treatment

Stoklasova Judith , Kaprova Jana , Trkova Marie , Nedomova Vera , Zemkova Daniela , Soucek Ondrej , Matyskova Jana , Sumnik Zdenek , Lebl Jan

Background: Terminal Xp-deletion causes a variant of Turner syndrome (TS). Several studies described the associated phenotype: gonadal function is generally preserved and short stature is the major clinical feature.Case presentation: We present a family with vertical transmission of TS affecting six women in four subsequent generations. SNP-array indicates that the chromosomal aberration in this family includes terminal Xp-deletion and terminal Xq-duplic...

Background: Following a phase of feeding difficulties and underweight in early life, children with Prader-Willi syndrome (PWS) develop hyperphagia and a tendency towards severe obesity. Growth hormone therapy (GH) has been approved in PWS to compensate their growth failure but may exert also additional effects on muscle component and body composition as well.Objectives: We aimed to test if an early initiation of GH thera...

The Validation of an Automated Bone Age Assessment in Girls with Turner Syndrome – A Pilot Study

Soucek Ondrej , Lebl Jan , Maratova Klara , Zemkova Dana , Sumnik Zdenek

Background: Bone age evaluation is a basic tool to manage the treatment of girls with Turner syndrome (TS). The current standard of care is to involve an experienced medical staff to use the Tanner Whitehouse 3 (TW3) or Greulich-Pyle (GP) method for manual evaluation of the bone age. As this is time consuming and may be partially influenced by the evaluatorÂ’s skills, automated systems may prove more efficient.Objective and hypothesis: The aim of thi...

Good Clinical Response to the Growth Hormone Therapy in the Patient with Familiar Short Stature Caused by Novel p.Val478Serfs*14 Mutation in ACAN Gene and Isolated Growth Hormone Deficiency

Pruhova Stepanka , Dusatkova Lenka , Dusatkova Petra , Zemkova Dana , Lebl Jan

Background: Recently a heterozygote mutations in the gene ACAN coding the protein aggrecan has been described as a cause of familiar short starture combined with accelerated bone age. The aggrecan is an extracellular proteoglycan in cartilage of growth plates and plays an important role in biological and biomechanical properties of cartilage.Objective and hypotheses: To provide a genetic screening of ACAN within the families with familiar short stature a...

A Case of Hutchinson-Gilford Progeria Syndrome (HGPS) due to a Pathogenic LMNA Variant c.433G>A (p.Glu145Lys): Growth Hormone Administration Failed to Improve Growth and Long-term Outcome

Toni Ledjona , Dušatkoa Petra , Novotna Dana , Zemkova Dana , PrUhova Štěpanka , Lebl Jan

Hutchinson-Gilford Progeria Syndrome (HGPS) is an extremely rare condition (estimated incidence 1:4–8 million), caused by mutations in LMNA gene, which leads to premature aging. Median life expectancy is shortened to 13 years due to vascular complications such as stroke or myocardial infarction. We present below the history of a child born with a pathogenic LMNA variant c.433G>A (p.Glu145Lys). A male patient was referred due to failure to thrive and low growth velocit...

Central Precocious Puberty and Autism: Three Cases Report

Amaral Daniela , Lopes Lurdes

Background: Central precocious puberty (CPP) is a rare disorder that occurs five times more often in girls. Patients are mostly healthy children whose pubertal maturation begins at an early age: girls <8 years; and boys <9 years. Imaging usually reveals no abnormalities in girls while in boys abnormal MRI findings are more frequent.Objective and hypotheses: We describe three cases of CPP in children with autism, a rarely reported association....

How to detect children with monogenic etiology of familial short stature?

Plachy Lukas , Petruzelkova Lenka , Dusatkova Petra , Maratova Klara , Zemkova Dana , Kolouskova Stanislava , Snajderova Marta , Obermannova Barbora , Sumnik Zdenek , Lebl Jan , Pruhova Stepanka

Introduction: Familial short stature (FSS) describes vertically transmitted growth disorders. Traditionally, polygenic inheritance is presumed, but monogenic inheritance seems to occur more frequently than expected. Clinical predictors of monogenic FSS have not been elucidated thus far. The aim of the study was to identify the monogenic etiology and its clinical predictors in FSS children.Patients and Methods: Of 747 pat...
