Abstract

WSTĘP. Celem pracy była ocena rozwoju somatycznego dzieci i młodzieży chorych na cukrzycę typu 1 oraz analiza zmian stężeń insulinopodobnego czynnika wzrostowego 1 (IGF-1, insulin-like growth factor-1) i jego białek wiążących IGFBP-1 i IGFBP-3 (insulin-like growth factor binding protein) w trakcie trwania choroby. Oceniano też wpływ sposobu leczenia na stężenia wyżej wymienionych czynników wzrostowych i parametry auksologiczne. MATERIAŁ I METODY. Do badań włączono 148 chorych na cukrzycę typu 1, leczonych metodą konwencjonalną i metodami wielokrotnych wstrzyknięć insuliny, w wieku 2-22 lat, u których choroba trwała 0-21 lat, i 54 zdrowych rówieśników. Oceniano u nich parametry auksologiczne i dojrzewanie płciowe. Krew do badań pobierano w godzinach 7.30-8.30 rano, na czczo. Surowicze stężenia IGF-1 oznaczano metodą radioimmunologiczną (RIA, radioimmunoassay), stężenia IGFBP-1 i IGFBP-3 metodą immunoradiometryczną (IRMA, immunoradiometric assay) a HbA1c przy użyciu wysoko rozdzielczej chromatografii cieczowej (HPLC, high performance liquid chromathography). Do analizy statystycznej wykorzystano test t-Studenta, ANOVA, regresję liniową i wieloczynnikową. WYNIKI. Wzrost dzieci i młodzieży z cukrzycą nie różnił się istotnie od wzrostu ich zdrowych rówieśników. Przy rozpoznaniu choroby był nieznacznie wyższy niż w grupie kontrolnej, w czasie jej trwania stopniowo się obniżał, by osiągnąć poziom nieistotnie niższy niż u zdrowych równolatków. Dojrzewanie płciowe dziewcząt i chłopców chorych na cukrzycę przebiegało podobnie, jak u zdrowych rówieśników w polskiej populacji, niezależnie od czasu trwania choroby. Wskaźnik SDS (standard deviation scores) dla wzrostu wszystkich badanych był większy niż przewidywany na podstawie wzrostu ich biologicznych rodziców. Stężenia IGF-1 były istotnie niższe, a stężenia IGFBP-3 wyższe u chorych na cukrzycę niż w grupie kontrolnej. Stężenia IGFBP-1 nie różniły się między grupami. Wzrost dzieci i młodzieży chorych na cukrzycę w okresie przed pokwitaniem korelował ze stężeniami IGF-1, IGFBP-1 i IGFBP-3, u wszystkich chorych na cukrzycę korelował on z dobowym zapotrzebowaniem na insulinę. Stwierdzono również zależność między stężeniami IGF-1 a dobowym zapotrzebowaniem na insulinę oraz wartościami HbA1c. Chorzy leczeni metodą wielokrotnych wstrzyknięć insuliny byli nieznacznie wyżsi mieli wyższe stężenia IGF-1 oraz niższe stężenia IGFBP-1 niż chorzy leczeni metodą konwencjonalną. WNIOSKI. Wyniki badań sugerują, iż rozwój somatyczny dzieci chorych na cukrzycę typu 1 zależy nie tylko od wpływu czynników genetycznych, ale również od właściwej podaży insuliny, którą najlepiej reguluje metoda intensywnej insulinoterapii, zapewniając prawidłowe stężenia IGF-1 i jego białek wiążących. Chorzy na cukrzycę, u których stężenia IGF-1 są obniżone, mogą osiągnąć wzrost w granicach normy dla wieku dzięki substytucji insuliny na poziomie zapewniającym prawidłowe stężenia IGFBP-1. Warunkują one odpowiednią bioaktywność IGF-1. INTRODUCTION. The aim of the study was evaluation of the somatic development and sexual maturation of children and adolescents with type 1 diabetes mellitus and estimation of their IGF-IGFBP system at the on-set of diabetes as well as during the progress of the disease. It was also analysed how the methods of insulinotherapy influence estimated growth factors and auxology parameters. MATERIAL AND METHODS. 148 diabetic patients without other diseases treated with conventional and intensive insulinotherapy with diabetes duration 0-21 years and 54 age-matched healthy children and adolescents 2-22 years old were included into the study. Their somatic and pubertal development were estimated by experienced physician and anthropologist. Blood samples were taken at 7.30-8.30 a.m., after 8h fasting. The serum concentrations of IGF-I were measured by RIA; IGFBP-1 and IGFBP-3 concentrations by IRMA and HbA1c by HPLC method. The data were analysed using test t-Student, ANOVA, linear and multiple regression analyses. RESULTS. The diabetic patients’ height did not differ from the height of healthy children and adolescents. At the onset of diabetes patients were not significantly taller than their healthy contemporaries but with the disease duration progress their growth slowly decreased and finally they reached lower level of height than in the control group (the difference didn’t reach statistical significance). Sexual maturation of diabetic patients did not differ from age related healthy polish population independently of diabetes duration. All diabetic and healthy children’s z score of height were higher than z score of mid-parental height. IGF-I concentrations were lower and IGFBP-3 concentrations were higher in diabetic patients than in the control group. IGFBP-1 levels did not differ in both groups. Before the onset of puberty patients’ height correlated with IGF-I, IGFBP-1, and IGFBP-3. In all diabetic patients height correlated with insulin requirement. IGF-1 concentrations correlated also with insulin requirement and HbA1c. Diabetic patients treated with intensive insulinotherapy were slightly taller and had higher IGF-1 and lower IGFBP-1 concentrations than patients treated with other methods of insulinotherapy. CONCLUSIONS. Somatic development of diabetic children depends not only on genetic influence, but also on adequate insulin substitution which could be achieved by intensive insulinotherapy. Despite decreased IGF-I levels, height within normal ranges was attained, probably because of adequate insulin compensation leading to normal IGFBP-1 levels, thus adequate IGF-I bioavailability.

Abstract

Among long-term survivors after hematopoietic stem cell transplantation (HSCT) late endocrine complications are observed in 20-50%. Very often these complications influence significantly the patient´s life and have to be treated till the end of life. Their proper prevention and monitoring are extremely important in patients who underwent HSCT during childhood. Since the 90s of the last millennium/century, thyroid dysfunction, disorders of somatic and sexual development, and disturbances of fertility have been presented in several publications. In the paper, less known endocrine complications after HSCT published in the last years are discussed. Disorders of carbohydrate metabolism, post-transplant diabetes and insulin resistance are presented. Moreover, dyslipidemia, hypertension, and post-transplant bone metabolic disease are demonstrated/shown. The paper describes the etiopathogenesis, methods of prevention as well as treatment and the results of the treatment of these endocrine complications after HSCT. Moreover, actual recommendations for screening and prevention of endocrine complications in long-term HCT survivors are presented.

Abstract

Since the 1980s, hematopoietic stem cell transplantation (HSCT) has been performed for malignant and non-malignant disorders leading to increasing numbers of long-term survivors. Some of them develop long-term posttransplantation complications, among them endocrine complications that arise many years after HSCT and demand to be treated till the end of patients´ life. In the paper "classical", observed several years after HSCT had been used as a treatment procedure, endocrine complications are discussed and the review of literature regarding this problem is presented. Thyroid dysfunction, disorders of somatic and sexual development are presented in details. Gonad dysfunction with the problem of fertility disturbances is reported. The paper presents the etiopathogenesis, methods of prevention, as well as treatment and the results of the treatment of these endocrine complications after HSCT. Moreover actual recommendations for screening and prevention of endocrine complications in long-term HCT survivors are presented.

Abstract

Introduction: Craniopharyngioma can cause neurological, ophthalmological and endocrine signs and symptoms., Aim of the Study: Retrospective analysis of symptoms accompanying diagnosis of craniopharyngioma in children., Material and Methods: 10 children and adolescents, 3.75-14.08 years old, median 8.96, treated in our centre in the years 1992-2010, with diagnosis of craniopharyngioma, were included into the study. In the analysis clinical symptoms at the moment of diagnosis, before surgery treatment were taken into consideration. Data from medical histories, physical examination, auxological data, biochemical and hormonal parameters were analyzed., Results: Among 10 patients, 9 had headaches, 4 had experienced vomiting, 2 had symptoms of cranial hypertension, 6 had vision disorders, 8 had endocrine disorders. A decrease of growth rate was observed in 5 children (among 7 with previous anthropometric data), diabetes insipidus in 2, gain of body weight and delayed puberty in 1, and secondary hypothyroidism in 1 patient. Endocrine disorders appeared on average 13 months before diagnosis of craniopharyngioma. Among them the earliest was the decrease of growth rate - on average 23 months before the diagnosis, and the latest diabetes insipidus - 2 months before it. The most frequent symptom - headaches appeared 2 months before the diagnosis., Conclusions: 1. Endocrine symptoms are early symptoms of craniopharyngioma, which usually appear before neurological, and ophthalmological disorders. 2. Craniopharyngioma may be a cause of growth disorders in children and adolescents, therefore a detailed analysis of height data on growth charts in pediatric patients is very important for the diagnosis.
