This study focuses on various rare genetic conditions characterized by impaired gonadal or adrenal functionality. Methods/Design: The study aims to assess quality of life (QoL) as a measure of psychosocial adaptation, psychosexual and mental health aspects as major outcomes. Health status and functioning, medical and surgical therapies, participants' views on health care, psychological and social support, sociodemographic factors and their interrelations will be investigated as factors associated with the outcomes. In addition, ethical considerations in the field of DSD are addressed and previous experiences with health care were gathered. One thousand and forty participants with different DSD conditions were recruited by 14 study centres in 6 European countries (France, Germany, the Netherlands, Poland, Sweden and the United Kingdom) from February 2014 until September 2015. The conditions included were: Turner syndrome (n = 301); 45,X0/46,XY conditions (n = 45); Klinefelter syndrome (n = 218); 47,XYY (n = 1); 46,XY gonadal dysgenesis/ovotestes (n = 63); complete androgen insensitivity (CAIS) (n = 71); partial androgen insensitivity (PAIS) (n = 35) and androgen synthesis disorders (n = 20); severe hypospadias (n = 25); other or non-classified 46,XY DSD (n = 8); 46,XX congenital adrenal hyperplasia (CAH) (n = 226); 46,XX gonadal dysgenesis/ovotestis (n = 21); and 46,XX in males (n = 6). For an add-on study, 121 46,XY male-assigned individuals with CAH due to 21-hydroxylase deficiency were recruited. Mean age of participants' was 32.4 (+/− 13.6 years).

Adipose tissue is producing bioactive substances called adipocytokines. Some of them may play a role in the development of insulin resistance. Aim of the study: Estimation of the frequency of insulin resistance and its correlation with leptin, adiponectin and resistin levels in children with simple obesity. Material and methods: The 53 children (BMI>97 centile), mean age 13.57 years. Mean BMI was +4.04 SDS. Oral glucose tolerance test (OGTT) was performed. Insulin levels at 0' < or = 15 microIU/mL and/or insulin peak during OGTT < or = 150 microIU/mL and/or peak at 120' < or =75 microIU/mL were established as normal values. Homa ratio was calculated. Patients were divided into groups depending on the presence or absence of hyperinsulinemia / insulin resistance. Concentrations of adiponectin, leptin, resistin were measured. Results: In 13.23 % children various types of hyperglycemia were diagnosed and hyperinsulinemia in OGTT was noted in 83.02 %. Severe insulin resistance (HOMA>3) was diagnosed in 71.82 %. In the hyperinsulinemia group higher glucose levels in OGTT were stated comparing to the non hyperinsulinemia group. In children with insulin resistance, higher BMI and SD BMI were observed. In this paper results of correlations of adipocytokines levels and anthropometric parameters or carbohydrates metabolism in children with / without insulin resistance are presented. Conclusions: In children with severe insulin resistance adiponectin concentrations correlate negatively with glucose levels, there is a positive correlation of adiponectin and glucose and insulin in a group without severe insulin resistance. In patients with insulin resistance leptin concentrations correlate positively with the degree of obesity and insulin levels in OGTT.

Research paper thumbnail of A Case of Two Sisters Suffering from 46,XY Gonadal Dysgenesis and Carrying a Mutation of a Novel Candidate Sex-Determining Gene STARD8 on the X Chromosome

Sexual Development, 2018

Here, we propose a member of the START domain family, the X chromosome STARD8, as a DSD candidate gene. We have identified a missense mutation of this gene in 2 sisters with 46,XY gonadal dysgenesis, inherited from their heterozygous mother. Gonadal tissue of one of the sisters contained Leydig cells overloaded with cholesterol droplets, i.e., structures previously identified in 46,XY DSD patients carrying mutations in the STAR gene encoding another START domain family member, which is crucial for steroidogenesis. Based on the phenotypes of our patients, we propose a dual role of STARD8 in sexual development, namely in testes determination and testosterone synthesis. However, further studies are needed to confirm the involvement of STARD8 in sexual development.

Research paper thumbnail of Endocrine disorders in a patient with a suspicion of a mitochondrial disease, MELAS syndrome – a case report and literature review

Pediatric Endocrinology Diabetes and Metabolism, 2021

We present a girl who was suspected of MELAS syndrome during the diagnostic evaluation of short stature. The patient suffered from symptoms potentially indicating mitochondrial disease, such as muscular weakness, cranial nerve VI palsy, headaches, retinitis pigmentosa, sensory-neural hearing loss, and elevated lactic acid. T2-weighted brain MRI showed hyperintense lesions in the white matter. Muscular biopsy revealed ragged red fibres. Genetic evaluation did not detect the most common mutations in the MT-TL1 gene and MT-ND5 gene. Endocrine tests led to the confirmation of growth hormone deficiency, and so replacement treatment was started. After 1 year of recombinant growth hormone therapy the patient was diagnosed with diabetes. At the age of 14 years the LH-RH test showed prepubertal values. Endocrine disorders may be one of the first manifestations of MELAS syndrome. In differential diagnosis of short stature, less common causes, such as mitochondrial diseases, should be taken into consideration.

It may be associated with anosmia, referred to as Kallmann syndrome, or a normal sense of smell. Numerous studies have proven that hypogonadotropic hypogonadism is not simply a monogenic Mendelian disease, but that more than one gene may be involved in its pathogenesis in a single patient. The oligogenic complex architecture underlying the disease is still largely unknown.Material and methodsTargeted next-generation sequencing (NGS) was used to screen for DNA variants in a cohort of 47 patients with congenital hypogonadotropic hypogonadism. The NGS panel consists of over 50 well-known and candidate genes, associated with hypogonadotropic state.ResultsHere we report the identification of new oligogenic variants in SPRY4/SEMA3A, SRA1/SEMA7A, CHD7/SEMA7A, CCDC141/POLR3B/POLR3B, and PRO...

We aimed to examine the incidence of different types of gonadal neoplasia and associated risk factors. Methods: A total of 1040 DSD patients aged ≥16 years participated in a cross-sectional multicentre European study (dsd-LIFE). Data on medical history were gathered from the patients' archival medical documents. A webbased questionnaire was filled out individually by the participants. A physical examination was performed in all, while ultrasonography of gonads was carried out in 214 and semen analysis was performed for 53 patients. Results: Germ-cell neoplasia was present in 12 % of patients with DSD and in 14 % of those with XY DSD. The highest risk (36 %) was observed in 46,XY patients with gonadal dysgenesis (GD): complete GD (33 %) and partial GD (23 %), but also in mixed GD (8 %) and complete androgen insensitivity syndrome (AIS) (6%). It was not reported in partial AIS, XX male, 46,XX DSD and congenital adrenal hyperplasia, Turner and Klinefelter syndromes, or in androgen biosynthesis defects. Benign sex cord-stromal tumours (Sertoli-and Leydig-cell tumours) were noted only in patients with complete AIS (3.1 %) and Klinefelter syndrome (14.3 %). A relationship between risk factors for GCT and gonadal neoplasia appearance, other than the Y chromosome, was not found. Conclusion: Adult patients with GD and the Y chromosome have the highest risk of GCT and should be kept under thorough medical control and receive special medical follow-up to prevent the development of gonadal tumours.

The aim of the study was to assess the following: the mental health status and the risk of mental problems in adult DSD patients, their dependence on therapeutic procedures, and to identify groups of disorders that require particular psychological support. Material and methods: The study involved 59 patients with DSD (gonadal dysgenesis-GD, androgen insensitivity syndrome-AIS, 5-alpha reductase deficiency, ovotestis), and with the Y chromosome in the karyotype, aged 16-65 years. All completed the General Health Questionnaire (GHQ-28) for the assessment of their mental health status. Raw results 2 were converted into sten scores using norms for the Polish adult population to assess the risk of mental problems. Results: A high risk of mental problems was identified in 24% of individuals (26% men, 21% women). Women, when compared with men, displayed a significantly higher mean level of anxiety and insomnia (7.3 vs. 4.6 scores) and somatic symptoms (7.4 vs. 5.5), and worse general mental health status (25.6 vs. 18.8). The most disturbing symptoms were observed among patients with complete and partial AIS, and complete GD (general mental health status: 39.5, 24.3, and 24.2, respectively), women lacking a vagina (27.2), and without an enlarged clitoris (27.5). Patients after genital surgery had significantly fewer somatic symptoms (5.4 vs. 7.8; p < 0.05) and better general mental health status in comparison to those without surgery (20.1 vs. 24.9; p < 0.05). No significant differences were observed between patients using hormone replacement therapy and those who were not. Conclusions: The individuals with DSD and Y chromosome in the karyotype have increased risk of developing mental problems in comparison to the general Polish population. The risk factors seem to be as follows: female gender, the lack of a vagina, the lack of virilisation (no enlarged clitoris), and no genital operations performed. In some cases, sex hormone replacement therapy may be also the risk of mental problems. Particularly vulnerable groups are CAIS, PAIS, and CGD. The psychological support and an individual approach to particular needs of these patients is necessary.

Research paper thumbnail of Expanding the mutational spectrum of monogenic hypogonadotropic hypogonadism: novel mutations in ANOS1 and FGFR1 genes

Reproductive Biology and Endocrinology, 2020

To date more than 30 genes have been associated with CHH pathogenesis with X-linked recessive, autosomal dominant, autosomal recessive and oligogenic modes of inheritance. Defective sense of smell is present in about 50–60% of CHH patients and called Kallmann syndrome (KS), in contrast to patients with normal sense of smell referred to as normosmic CHH. ANOS1 and FGFR1 genes are all well established in the pathogenesis of CHH and have been extensively studied in many reported cohorts. Due to rarity and heterogenicity of the condition the mutational spectrum, even in classical CHH genes, have yet to be fully characterized. Methods To address this issue we screened for ANOS1 and FGFR1 variants in a cohort of 47 unrelated CHH subjects using targeted panel ...

Research paper thumbnail of Endocrine disorders in a patient with a suspicion of a mitochondrial disease, MELAS syndrome – a case report and literature review

Pediatric Endocrinology Diabetes and Metabolism, 2021

We present a girl who was suspected of MELAS syndrome during the diagnostic evaluation of short stature. The patient suffered from symptoms potentially indicating mitochondrial disease, such as muscular weakness, cranial nerve VI palsy, headaches, retinitis pigmentosa, sensory-neural hearing loss, and elevated lactic acid. T2-weighted brain MRI showed hyperintense lesions in the white matter. Muscular biopsy revealed ragged red fibres. Genetic evaluation did not detect the most common mutations in the MT-TL1 gene and MT-ND5 gene. Endocrine tests led to the confirmation of growth hormone deficiency, and so replacement treatment was started. After 1 year of recombinant growth hormone therapy the patient was diagnosed with diabetes. At the age of 14 years the LH-RH test showed prepubertal values. Endocrine disorders may be one of the first manifestations of MELAS syndrome. In differential diagnosis of short stature, less common causes, such as mitochondrial diseases, should be taken into consideration.

It may be associated with anosmia, referred to as Kallmann syndrome, or a normal sense of smell. Numerous studies have proven that hypogonadotropic hypogonadism is not simply a monogenic Mendelian disease, but that more than one gene may be involved in its pathogenesis in a single patient. The oligogenic complex architecture underlying the disease is still largely unknown.Material and methodsTargeted next-generation sequencing (NGS) was used to screen for DNA variants in a cohort of 47 patients with congenital hypogonadotropic hypogonadism. The NGS panel consists of over 50 well-known and candidate genes, associated with hypogonadotropic state.ResultsHere we report the identification of new oligogenic variants in SPRY4/SEMA3A, SRA1/SEMA7A, CHD7/SEMA7A, CCDC141/POLR3B/POLR3B, and PRO...

We aimed to examine the incidence of different types of gonadal neoplasia and associated risk factors. Methods: A total of 1040 DSD patients aged ≥16 years participated in a cross-sectional multicentre European study (dsd-LIFE). Data on medical history were gathered from the patients' archival medical documents. A webbased questionnaire was filled out individually by the participants. A physical examination was performed in all, while ultrasonography of gonads was carried out in 214 and semen analysis was performed for 53 patients. Results: Germ-cell neoplasia was present in 12 % of patients with DSD and in 14 % of those with XY DSD. The highest risk (36 %) was observed in 46,XY patients with gonadal dysgenesis (GD): complete GD (33 %) and partial GD (23 %), but also in mixed GD (8 %) and complete androgen insensitivity syndrome (AIS) (6%). It was not reported in partial AIS, XX male, 46,XX DSD and congenital adrenal hyperplasia, Turner and Klinefelter syndromes, or in androgen biosynthesis defects. Benign sex cord-stromal tumours (Sertoli-and Leydig-cell tumours) were noted only in patients with complete AIS (3.1 %) and Klinefelter syndrome (14.3 %). A relationship between risk factors for GCT and gonadal neoplasia appearance, other than the Y chromosome, was not found. Conclusion: Adult patients with GD and the Y chromosome have the highest risk of GCT and should be kept under thorough medical control and receive special medical follow-up to prevent the development of gonadal tumours.

The aim of the study was to assess the following: the mental health status and the risk of mental problems in adult DSD patients, their dependence on therapeutic procedures, and to identify groups of disorders that require particular psychological support. Material and methods: The study involved 59 patients with DSD (gonadal dysgenesis-GD, androgen insensitivity syndrome-AIS, 5-alpha reductase deficiency, ovotestis), and with the Y chromosome in the karyotype, aged 16-65 years. All completed the General Health Questionnaire (GHQ-28) for the assessment of their mental health status. Raw results 2 were converted into sten scores using norms for the Polish adult population to assess the risk of mental problems. Results: A high risk of mental problems was identified in 24% of individuals (26% men, 21% women). Women, when compared with men, displayed a significantly higher mean level of anxiety and insomnia (7.3 vs. 4.6 scores) and somatic symptoms (7.4 vs. 5.5), and worse general mental health status (25.6 vs. 18.8). The most disturbing symptoms were observed among patients with complete and partial AIS, and complete GD (general mental health status: 39.5, 24.3, and 24.2, respectively), women lacking a vagina (27.2), and without an enlarged clitoris (27.5). Patients after genital surgery had significantly fewer somatic symptoms (5.4 vs. 7.8; p < 0.05) and better general mental health status in comparison to those without surgery (20.1 vs. 24.9; p < 0.05). No significant differences were observed between patients using hormone replacement therapy and those who were not. Conclusions: The individuals with DSD and Y chromosome in the karyotype have increased risk of developing mental problems in comparison to the general Polish population. The risk factors seem to be as follows: female gender, the lack of a vagina, the lack of virilisation (no enlarged clitoris), and no genital operations performed. In some cases, sex hormone replacement therapy may be also the risk of mental problems. Particularly vulnerable groups are CAIS, PAIS, and CGD. The psychological support and an individual approach to particular needs of these patients is necessary.

Research paper thumbnail of Expanding the mutational spectrum of monogenic hypogonadotropic hypogonadism: novel mutations in ANOS1 and FGFR1 genes

Reproductive Biology and Endocrinology, 2020

To date more than 30 genes have been associated with CHH pathogenesis with X-linked recessive, autosomal dominant, autosomal recessive and oligogenic modes of inheritance. Defective sense of smell is present in about 50–60% of CHH patients and called Kallmann syndrome (KS), in contrast to patients with normal sense of smell referred to as normosmic CHH. ANOS1 and FGFR1 genes are all well established in the pathogenesis of CHH and have been extensively studied in many reported cohorts. Due to rarity and heterogenicity of the condition the mutational spectrum, even in classical CHH genes, have yet to be fully characterized. Methods To address this issue we screened for ANOS1 and FGFR1 variants in a cohort of 47 unrelated CHH subjects using targeted panel ...
