ABSTRACT

Allogeneic hematopoietic stem cell transplantation (HSCT) has become a standard part of therapy for a variety of malignant and non-malignant disorders. With improved outcomes after HSCT, increasing attention has been drawn to late complications in long-term survivors. The development of secondary malignancies is recognized as one of the most serious complications. We have evaluated data from 426 patients (272 males, 154 females) who underwent allogeneic transplantation at a median age of 7.9 years from 1989 till 2017 and were alive more than one year after transplantation for the occurrence of secondary solid tumors. We have documented the occurrence of secondary solid tumors in 20 patients (4.7%). The median duration of the development of secondary solid cancer from HSCT was 11.7 (range, 5.4-21.5 years). 18 out of 20 patients (90%) had total body irradiation (TBI) 12-14.4 Gy as a part of a conditioning regimen. All but two had transplantation for malignant disease. All patients underwent surgery and/or chemo-radiotherapy. Eighteen are alive, and two died due to the progression of their secondary malignancy. The most frequent solid cancer was thyroid carcinoma (n=9). Cumulative incidence of secondary solid cancer in all groups was 15.2±3.9%, in a group using TBI based regimen 34.7±8.9%, in non-TBI (only chemo) group was 1.5±1.1%. Overall, the cumulative incidence is statistically significantly different between the TBI based and non-TBI (chemo only) group. The incidence and number of complications following allogeneic HSCT in childhood are increasing in time. The early diagnosis of secondary malignancies is one of the key tasks of long-life multidisciplinary post-transplant care.

ABSTRACT

A child born with ambiguous genitalia (Prader III) was found to have a 45,X[92.2%]/46,X,psu dic(Y)(p12)[7.8%] karyotype in peripheral blood lymphocytes. The testosterone level was consistent with that of a normal male; however, gonadotropins were elevated. Ultrasound and endoscopy of the urogenital sinus revealed well-developed Müllerian structures. At 3.5 months, the child was operated for right-sided incarcerated hernia, and the gonad situated at the inguinal region was biopsied and classified as primitive testis. Based on the presence of Müllerian structures, anatomy of external genitalia and wish of the parents, the child was assigned female gender. She underwent removal of the left gonad at 4 months during another acute surgery; histology was similar to the right gonad. The rest of the right gonad was removed at 16 months, and feminizing genitoplasty took place at 3 years. The right and left gonad contained 28 and 22% of cells with a Y chromosome, respectively. During further histological examination, dysgenetic features of the gonads were discovered. Some germ cells displayed abnormal development based on the specific expression of immunohistochemical markers (OCT3/4, TSPY, KITLG), indicating a possible risk for future malignant germ cell tumor development. Contribution of the 45,X cell line to the phenotype was also observed: the patient developed celiac disease, and her growth pattern resembled that of Turner syndrome responding to growth hormone treatment.

ABSTRACT

CONTEXT: The low bone mineral density (BMD) and alterations in bone geometry observed in patients with Turner syndrome (TS) are likely caused by hypergonadotropic hypogonadism and/or by haploinsufficiency of the SHOX gene. OBJECTIVE: Our objective was to compare BMD, bone geometry, and strength at the radius between prepubertal girls with TS and children with isolated SHOX deficiency (SHOX-D) to test the hypothesis that the TS radial bone phenotype may be caused by SHOX-D. DESIGN AND SETTING: This comparative cross-sectional study was performed between March 2008 and May 2011 in 5 large centers for pediatric endocrinology. PATIENTS: Twenty-two girls with TS (mean age 10.3 years) and 10 children with SHOX-D (mean age 10.3 years) were assessed using peripheral quantitative computed tomography of the forearm. MAIN OUTCOMES: BMD, bone geometry, and strength at 4% and 65% sites of the radius were evaluated. RESULTS: Trabecular BMD was normal in TS (mean Z-score = -0.2 ± 1.1, P = .5) as well as SHOX-D patients (mean Z-score = 0.5 ± 1.5, P = .3). At the proximal radius, we observed increased total bone area (Z-scores = 0.9 ± 1.5, P = .013, and 1.5 ± 1.4, P = .001, for TS and SHOX-D patients, respectively) and thin cortex (Z-scores = -0.7 ± 1.2, P = 0.013, and -2.0 ± 1.2, P < .001, respectively) in both groups. Bone strength index was normal in TS as well as SHOX-D patients (Z-scores = 0.3 ± 1.0, P = .2, and 0.1 ± 1.3, P = .8, respectively). CONCLUSIONS: The similar bone geometry changes of the radius in TS and SHOX-D patients support the hypothesis that loss of 1 copy of SHOX is responsible for the radial bone phenotype associated with TS.

ABSTRACT

OBJECTIVE: The study summarizes data on genes responsible for development of gonads and subsequently of additional structures of genital system in humans. It comprises the effect of gene defects on clinical phenotype. SUBJECT: Review article. SETTING: Department of Pediatrics, University Hospital Motol and 2nd Faculty of Medicine, Charles University in Prague. SUBJECT AND METHOD: We present the overview of genes that contribute to development of genital system. Special emphasis is given on patient's phenotype related with various genetic disorders. Data were mainly found on Pubmed or OMIM web-sites according to key words "sex development" and "sex determination". We focused on ten genes with known relation to gonadal development--SRY, SOX9, SF1, DAX1, WNT4, WT1, DMRT1, DHH, RSPO1, ATRX. CONCLUSION: Sex development is a complex process orchestrated by numerous genes. Here we collect information on gene defect (gene mutations or defective number of gene copies) that cause gonadal maldevelopment with effects on final phenotype. Currently, genetic background of numerous disorders can be detected. That allows not only to verify the diagnosis but also to predict the future sexual development and genetic risk for other family members.

ABSTRACT

OBJECTIVE: To analyse data on psychomotor and cognitive development of children born after intracytoplasmic sperm injection (ICSI). DESIGN: Open cross-section clinical study. SETTING: Institute for the Care of Mother and Child, Prague and Department of Paediatrics, Charles University, 2nd Medical School and University Hospital Motol, Prague. METHODS: In 133 children (75 boys and 58 girls) psychological examination was made at the age range 11 months - 8.5 years in the years 2004-2006. All children were born after intracytoplasmic sperm injection (ICSI). Psychomotor development of children aged from 11 months to 3.5 years was assessed using the Bayley Scales (BSID-II). In older children, Global Intelligence McCarthy Test was used. RESULTS: In our sample of ICSI-children, no significantly higher incidence of children delayed in mental (cognitive) as well as in motor development has been found as compared with the population norms. However, the results indicate a significantly lower average value of the Psychomotor Developmental Index (PDI) in the group of younger children as compared with the given norm (92.3 +/- 13.9 versus 100 +/- 15; p<0.01). In the group of older children, lower average value of the General Cognitive Index (GCI), as compared with corrected population norm has been found (105.1 +/- 14.7 versus 110 +/- 16; p<0.05). In the group of twins, a significantly higher number of mild developmental disorders was ascertained on the contrary in the group of singletons (64.7% versus 333%; p<0.01) in our older children conceived by ICSI. CONCLUSION: The results indicate only mild lowering of some performances in our ICSI-children: in motor domain in younger children, and in cognitive domain in older children. Children from multiple pregnancies are at greater developmental risk than singletons.

ABSTRACT

OBJECTIVE: To analyze parental attitudes and socio-emotional development of children conceived by ICSI. DESIGN: Open cross-sectional study. SETTING: Department of Clinical Psychology, Thomayer University Hospital, Prague and Department of Paediatrics, Charles University, 2nd Medical School, University Hospital-Motol, Prague. METHODS: 133 children (75 boys, 58 girls) conceived by ICSI, age ranged from 11 months to 8.5 years were psychologically assessed between the years 2004-2006. Children's behavior was evaluated by 4 rating scales during the assessment. Parents answered questionnaires concerning children's temperament, behavioral problems (TBC) and the parental attitudes questionnaire (PARQ). RESULTS: Children's behavior during the psychological assessment was rated mostly as very good or good, although the children were often less communicative. Most of the children have mixed or easy temperament, a difficult type of temperament didn't report any of the parents. Most of the parents didn't describe significant behavioral problems in their children, in particular there were very few externalizing difficulties (opposition, aggression), but in 29.5% of the sample, there were found some social or emotional difficulties. We found surprisingly high frequency of milder forms of autism spectrum disorders and another social problems (social and other anxiety disorders) in the sample, other psychopathology was rare. Parental attitudes had a tendency to grater involvement with the child and high affection in relation with him. CONCLUSION: Socio-emotional development of ICSI children is good, although some have specific social difficulties, externalising problems were present only exceptionally. Parental attitudes toward ICSI children are positive, there is slight tendency to higher emotional involvement with the child.

ABSTRACT

OBJECTIVE: To analyze the type of infertility, pregnancy and neonatal outcome in children conceived after intracytoplasmic sperm injection (ICSI children). DESIGN: Prospective open cross-sectional clinical study. SETTING: University hospital and private IVF unit. METHODS: Type of infertility, pregnancy complications, neonatal period and neonatal characteristics were evaluated in 135 newborns conceived after ICSI from singleton and twin pregnancies and compared to general population. RESULTS: The percentage of twins was significantly higher after ICSI compared to general population (31% versus 1.7%; p<0.001) as well as the percentage of caesarean section deliveries (31% versus 17.8%; p<0.001). Some complication in neonatal period was found in 21.5% ICSI newborns (18 out of 42 twins and 12 out of 93 singletons; p< 0.001). Some complication during the course of pregnancy was found in 50.9% ICSI children. CONCLUSIONS: no differences in gestational age, birth weight and birth length were found when ICSI and spontaneously conceined (sc) singletons and ICSI and SC twins were compared. However, complications during the course of pregnancy and in the neonatal period were more frequent in ICSI conceived children.

ABSTRACT

OBJECTIVE: To analyze the incidence of birth defects, medical outcome and somatic development in children conceived after intracytoplasmic sperm injection (ICSI). DESIGN: Prospective open cross-sectional clinical study. SETTING: University hospital and private IVF unit. METHODS: 135 Czech children (59 girls, 76 boys) from singleton and twin pregnancies conceived after ICSI (age 03-9.5 years; median 5.9) were assessed during the period 2004-2006. The incidence of birth defects, medical outcome and somatic development were evaluated and compared with data of general population and/or with control group matched for sex and age. RESULTS: Birth defects were found in 133% of ICSI children (compared to 4.6% in children after spontaneous conception; p<0.001). The general health of ICSI children did not differ significantly compared to general population. ICSI children required more surgery or hospitalization compared to general population data. There is high rate (69.6%) among ICSI children in the care of various specialised clinics. Body height and weight in ICSI children is in normal range and corresponds to their growth potential. Head circumference in ICSI children is larger compared to reference data (0.43 SD; p<0.001). CONCLUSIONS: No clinically important differences in somatic development between ICSI and general population of Czech children were found. Birth defects were more frequent in ICSI children. The overall general health in ICSI children seems satisfactory but ICSI children were more likely to need health care compared to general population.

ABSTRACT

OBJECTIVE: To summarize available data concerning adrenal hyperandrogenemia caused by 21-hydroxylase deficiency, non-classic adrenal hyperplasia (NCAH). DESIGN: Review article. SETTING: Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Medical Faculty, Prague. METHODS: Compilation of published data from scientific literature. CONCLUSION: Although 21-hydroxylase deficiency is one of the most frequent autosomal recessive genetic disorders, prevalence of NCAH in the whole population and among hyperandrogenic women is very low. The measurement of 17OH-progesterone should be incorporated into the standard evaluation of all hyperandrogenic patients to establish or exclude the diagnosis of NCAH. There is no typical clinical sign of NCAH, and clinical symptoms are to similar to patients with PCOS. Corticoid substitution as a treatment modality of NCAH is derived from therapy of classic congenital adrenal hyperplasia (CAH). Anti-androgen therapy is effective in skin disorders (hirsutism). Due to normal cortisol value there is to use of combined oral contraceptives in the treatment of choice. An improvement of clinical symptoms is a key parameter for the evaluation of treatment effectiveness. There are no data about risk of late metabolic complications in NCAH patients.

ABSTRACT

OBJECTIVE: To evaluate hormonal suppression and pubertal development in children with central precocious puberty (CPP) after injection of triptoreline 11.25 mg (Diphereline S. R. 11.25 mg; Ipsen) in the first treatment cycle of 12 weeks. DESIGN: Pilot study. SETTING: Paediatric department, University Hospital Motol-Prague. METHODS: Serum levels of FSHmax and LHmax and basal levels of estradiol/testosterone were monitored in GnRH test before, 4, 8 and 12 weeks after triptoreline 11.25 mg injection in 3 girls and 2 boys with CPP (age 3.9-10.6 years) previously treated by triptoreline 3 mg every 4 weeks. Uterine and ovarian volume, hormonal cytology (vaginal smear), breast development and testicular volume were evaluated before and 12 weeks after triptoreline 11.25 mg injection. RESULTS: 8 weeks after triptoreline 11.25 mg, FSHmax in girls increased (2.3 IU/l vs. 1.7 IU/l before injection; median) without any other change in 12th week. In boys after initial decrease LHmax 12 weeks after injection rose to 1.7 IU/l (identical as LHmax before injection). Estradiol and testosterone levels were in prepubertal range. Pubertal development in girls did not progress, and testicular volume decreased in both boys (treated for CPP 0.3 and 0.7 years). CONCLUSIONS: Triptoreline 11.25 mg injection in 12 weeks interval can be considered as effective, useful and safe for therapy of CPP. The long-term follow-up will be necessary.

ABSTRACT

In this article the pregnancy of a woman suffering from the complete triad typical of Autoimmune Polyglandular Syndrome Type 2 (Addison's disease + type 1 diabetes + Hashimoto's thyroiditis) is reported. By using insulin pump therapy with insulin lispro, it was possible to balance diabetes control with changes of steroid replacement therapy. Pregnancy was uneventful until week 27, when signs of preeclampsia occurred. The boy was born without difficulty at gestational age 37 weeks by planned cesarean section but signs of diabetic fetopathy (macrosomia, hypoglycaemia and hypocalcaemia) were expressed. He required a short course of hydrocortisone therapy. He made a good and rapid recovery. The mother made a good post-operative recovery too, but 4 months after the delivery microalbuminuria as well as mild hyperuricemia are still present. Interdisciplinary approach and very careful observation of the mother as well as of the child enabled successful outcome of this highly risky pregnancy.

ABSTRACT

PURPOSE OF INVESTIGATION: Infertility represents one of the main sequelae of cytotoxic therapy given for various malignant diseases. Because dividing cells are more sensitive to cytotoxic effects than are cells at rest, it has been hypothesized that inhibition of the pituitary-gonadal axis may facilitate the preservation of future gonadal function. The aim of our study was to find a quick, reliable and economic way to suppress the pituitary-gonadal axis by combining GnRH-agonists with GnRH-antagonists in order to preserve future gonadal function. METHODS: A combination of D-Trp6-GnRH-a (3.75 mg) and cetrorelix (3 mg) was used to achieve a quick downregulation in six postmenarchal young women (aged 15.4 +/- 0.7) years with haematological malignancies before the onset of cytotoxic chemotherapy. RESULTS: The combination of D-Trp6-GnRH-a and GnRH-antagonist cetrorelix induced a reliable and long-lasting suppression of gonadotrophin secretion within 96 hours in all patients allowing cytotoxic therapy to be started without any delay. CONCLUSIONS: The combination of GnRH-agonist and GnRH-antagonist enables a rapid, reliable and cost-effective suppression of the pituitary-gonadal axis to be achieved. Future gonadal function of treated patients will be monitored.

ABSTRACT

OBJECTIVE: We describe a case of 23 years old woman who, with a history of car accident at the age of 11 and severe head injury, attended our Center of Reproductive Medicine complaining of primary infertility. The accident preceded menarche and the development of inner genitalia (uterus 46 mm, cervix:corpus ratio 1:1) as well as secondary sexual development was not fully accomplished. Ovarian failure was accompanied by amenorrhea, if not substituted. Under replacement therapy regular menstruation was established. Basal hormonal levels was extremely low (FSH and LH 0.2-0.3 IU/l, PRL 0.5 ng/ml, estrogens 0.08 nmol/l, PRGE was not detected). With oral administration of micronized estradiol (Check et al., 2001) endometrial thickness of 9 mm was achieved. All of five retrieved oocytes were fertilized with partner sperm (normospermy) and three embryos were transferred. Already the first attempt was successful. Patient suffered with transitional anorexia and vomiting which could be handled conservatively. Hormonals level were normal. Patient substituted with Hydrocortison and Euthyrox. On January 2, 2003 the pregnancy was finished by caesarian section, one week before the delivery term (girl, 2970, Apgar score 10-10-10). DESIGN: Case report. SETTING: Center of Reproductive Medicine, Zlin. CONCLUSION: This care report demonstrates that recent progress in assisted reproduction field enables to manage successfully even exceptional pathological conditions.

ABSTRACT

OBJECTIVE: Type 1 diabetes mellitus (DM1) is frequently accompanied by thyroid autoimmunity (TAI). The aims of the present study were to estimate the prevalence of TAI and to determine the contribution of HLA-DQA1 and -DQB1 polymorphisms to TAI susceptibility among children with DM1. PATIENTS AND METLHODS: Screening for TAI was performed in 285 children with DM1 by measuring autoantibodies against thyroid peroxidase (anti-TPO) and thyroglobulin (anti-Tg). HLA-DQA1 and -DQB1 were genotyped using PCR-SSP. RESULTS: Repeated positivity of anti-TPO and/or anti-Tg was found in 45/285 children with DM1 (15.8%). The prevalence was significantly higher in girls than in boys (26.7% vs 6.7%; p<10(-5)). The HLA-DQB1*0302 allele conferred susceptibility to TAI in children with DM1 (OR 2.7, 95% CI 1.1-6.4), while the DQB1*05 alleles acted protectively (OR 0.2, CI 95% 0.08-0.7). CONCLUSIONS: HLA-DQ polymorphisms significantly modify the risk of TAI in children with DM1.

ABSTRACT

BACKGROUND: Survival from cancer continues to improve. Antimitotic therapy can induce failure of spermatogenesis and oogenesis, gonadal disturbances and infertility. Recent advances in reproductive medicine have opened opportunities for the preservation of reproductive potential of patients with cancer. The aim of our study was to analyse by a multidisciplinary team the contemporary state of art and proposal of the Czech model of fertility preservation starting in childhood and continuing through the whole reproductive period. METHODS: This paper highlights the problems associated with gonadal failure as a consequence of therapy for malignancy in childhood, adolescence and adulthood. Analysis of these problems served as a principle for the management strategy for fertility preservation. CONCLUSIONS: Patients undergoing treatment for malignancy are at the high risk of gonadal damage and infertility. Therefore, alternative treatments with less gonadal toxicity and different treatment protocols were evaluated. Fertility can be preserved with the freezing and banking of spermatozoa, embryos, and oocytes obtained prior to the cancer treatment. In female patients (starting in puberty) pharmacological preservation of gonads with gonadoliberin analogues is also possible. Chance for the future fertility preservation for children offers freezing and thawing of primordial follicles and spermatozoa obtained during the gonadal biopsies. Long-term follow-up study by a multidisciplinary medical team is necessary.

ABSTRACT

Diagnosis of autoimmune beta cell destruction by genetic risk analysis, autoantibody evaluation and the test of stimulated insulin secretion performance in first-degree relatives of diabetic patients. 208 Czech children and adults (101 boys and 107 girls, 186 siblings, 22 offspring of diabetic parents, aged 1-22 years, mean age 11.5 +/- 5.4 years) were enrolled in the study. Complete DQB1, DQA1 typing and DRB1*04 subtyping were performed by the PCR in 202 subjects. Sera of all children were investigated for anti-GAD65, anti-IA2 and insulin antibodies using RIA methods. The cut-off normal levels were determined as the 99th percentile of 105 non-diabetic children. IVGTT was performed in children with significant titre of one or more autoantibodies. Total level of stimulated insulin secretion < 48 mU/l was assessed as defect of FPIR. Risk genotype DQA1*05-DQB1*0201/DQA1*03-DQB1*0302 (OR = 100, CI 95% 13-730) was found in 24 of 202 first-degree relatives (12%). 22 children (11%) carried strong protective allele DQB1*0602 (OR = 0.03, CI 95% 0.01-0.12). Autoantibody positivity was recognised in 9 of 208 children (2.9%) and IVGTT was performed. Positivity of anti-GAD65, anti-IA2 or IAA was identified in 5 of 24 children with the highest risk genotype (21%) and in 4 children of 113 with lower risk or neutral genotypes (3.5%). Borderline positivity of one autoantibody was found in 1 boy with the highest risk genotype and in 2 children with lower risk genotypes. Only temporary anti-GAD65 positivity was found in girl with protective genotype. Type 1 diabetes mellitus was diagnosed in boy during IVGTT and disease manifested 6 months after IVGTT in girl with defect of FPIR. Standardised methods for prediction of Type 1 diabetes were introduced in first-degree relatives of diabetic patients. These methods are used for Czech registry of diabetic children.

ABSTRACT

We investigated the association of the CTLA4 +49 A/G dimorphism with type 1 diabetes in Czech children. Genotyping of 305 diabetic children and 289 controls by a novel PCR-ARMS assay revealed no significant differences in the genotypic or allelic frequencies. This may be another piece of evidence against the +49 A/G transition as the aetiological polymorphism within the CTLA4 gene.

ABSTRACT

OBJECTIVE: To analyse growth and development of girls with slowly progressive idiopathic precocious or early puberty. DESIGN: Long-term open clinical study. SETTING: Department of Obstetrics and Gynaecology, Second Faculty of Medicine, Charles University, Prague. METHODS: In 20 untreated girls with slowly progressive puberty starting at 6-9 years neurogenic aetiology was excluded. During follow-up period 4.7 +/- 2.2 (2-8.5) years (mean +/- SD; range), sexual development (Tanner criteria), age at menarche, menstrual cycle and auxological parameters were evaluated. RESULTS: 13 girls reached menarche at 11.1 +/- 0.9 years (3.7 +/- 1.1 years after the onset of puberty), earlier than in their mothers (12.9 +/- 1.1 years) and Czech standards (P < 0.05). Menstrual cycle 28 (24-29) days was regular in all 6 girls with gynaecological age > 2 years. In one girl microprolactinoma was diagnosed, therapy with bromocryptine started at the age 14.7 years (3.5 years after menarche). At the onset of follow-up, bone age (TW20) advancement was 1.8 +/- 1.4 years above the chronologic age. Initial prediction of final height (graphic method) was 162.3 +/- 5.5 cm vs final prediction 163.7 +/- 5.1 cm. Final height 162.2 +/- 5.7 cm achieved 7 girls vs target height 163.6 +/- 5.2 cm (NS). CONCLUSION: In untreated girls, menarche occurred later after the first signs of puberty than in normal population, menstrual cycle was regular. Height potential was preserved, final height corresponded with their target height. Not all girls with early and slowly progressive puberty should be treated. Therapy is necessary in organic aetiology, rapid progressive precocious puberty and impaired growth prognosis.

ABSTRACT

BACKGROUND: Girls and adolescents with Turner syndrome (TS) usually receive intensive medical care in a multidisciplinary team, coordinated by paediatric endocrinologist. Majority of them are discharged from specialist clinics following the induction of puberty and attainment of final height. Patients with Turner syndrome have a reduced life expectancy, they are known to have multi-system impairments in addition to the short stature and to the absence of sexual development. Aim of this study is to propos a continuous follow-up by multidisciplinary team of physicians starting in childhood and following the discharge from the paediatric care. METHODS AND RESULTS: This paper highlights the medical and psychosocial problems associated with Turner syndrome in childhood, adolescence and in adulthood. Analysis of these problems served as a background to management strategy. CONCLUSIONS: Women with Turner syndrome are at risk of number of medical problems. Quality of their life and the life expectancy can be improved with increasing awareness to comorbities associated with Turner syndrome. Assisted reproduction technologies has recently offered a chance for pregnancy and delivery of a healthy child also to women with Turner syndrome. Therefore, long-term follow-up by multidisciplinary team of physicians knowledgeable about these medical problems is necessary. Introduction of a centralised system of systematic multidisciplinary approach to patients with Turner syndrome from childhood and adolescence to adulthood seems to be very important.
