Neonatal hyperthyroidism – discussions on three clinical cases

Ramona Stroescu, Elena Pop, Monica Marazan, Teofana Bizerea and Ioana Micle

ABSTRACT

Introduction: Neonatal hyperthyroidism occurs în infants from mothers with Graves Basedow, with an incidence of 1:70.

Purpose: Highlighting the risks and complications that may appear în infants of mothers with Graves’ disease.

Method: The cases of three newborns resulted from risk pregnancies (mothers known with Graves’ disease) diagnosed with neonatal hyperthyroidism, are addressed. Admission status and evolution of each case were different, depending on the mother’s compliance regarding the treatment and on the mothers (TSI) antibody levels. în the first case, admitted at the age of one day with thyrotoxicosis, the mother interrupted treatment throughout pregnancy. In the two cases which followed treatment during pregnancy, mothers TSI level during pregnancy was different: the patient with high TSI levels originally developed subclinical hypothyroidism due to transplacental passage of oral antithyroid medication, subsequently developing clinical symptoms of hyperthyroidism (agitation, tachycardia, growth retardation). In the third case, the mother’s hard to control, persistent, thyrotoxicosis, throughout the whole pregnancy, affected the intrauterine development (gestational week 33 weeks). He presented with a mild form of hyperthyroidism caused by low amounts TSI antibodies during the pregnancy. The evolution was favorable with the normalization of the thyroid function; at the age of 3 months, no maternal antibodies have been detected in infants.

Discussion: The risk of newborn thyrotoxicosis represents an emergency, antithyroid treatment followed by the mother has an essential role; high doses increase the risk of perinatal hypothyroidism. The severity of the symptoms depends on the antibody (TSI) levels which cross the placenta.

Conclusions: Monitoring the newborn from mothers with Graves’ disease is essential; it should begin from the intrauterine period and continued until at the age of 3-6 months. Reaching euthyroidism în both mother and the newborn is difficult to obtain and requires interdisciplinary collaboration

Key words: newborn, transient neonatal hypo-/hyperthyroidism, Grave’s disease

HIPERTIROIDISMUL NEONATAL – CONSIDERATII PE MARGINEA A TREI CAZURI

Ramona Stroescu, Elena Pop, Monica Marazan, Teofana Bizerea and Ioana Micle

REZUMAT

Introducere: hipertiroidismul neonatal apare la nou-născuţii din mamă cu Graves Basedow, frecvenţa bolii fiind de 1:70. Scopul lucrării: sublinierea complicaţiilor ce pot să apară la nou-născuţii proveniţi din aceste mame.

Material şi metodă: prezentarea a trei nou-născuţi provenind din sarcini cu risc (mame cunoscute cu Graves) diagnosticaţi cu hipertiroidism neonatal. Starea la internare şi evoluţia cazurilor au fost diferite, în funcţie de tratamentul urmat/sau nu şi de titrul de anticorpi (TSI) al mamei pe parcursul sarcinii. La primul caz, internat la vârsta de o zi cu tireotoxicoză, mama a întrerupt tratamentul pe parcursul sarcinii. La cazurile cu tratament urmat, TSI-ul mamei pe parcursul sarcinii a fost diferit: nou-născutul provenind din mamă cu TSI mare a dezvoltat iniţal hipotiroidism subclinic datorită pasajului transplacentar de antitiroidiene orale, ulterior dezvoltând simptomatologie clinică de hipertiroidism (agitaţie, tahicardie, curbă ponderală staţionară). Tireotoxicoza mamei greu controlabilă medicamentos la cazul trei a influenţat dezvoltarea intrauterină a fătului (vârsta gestaţională = 33 săptămâni). TSI-ul relativ mic pe tot parcursul sarcinii a determinat o formă uşoară de hipertiroidism la aces nou-născut. Evoluţia a fost favorabilă cu normalizarea funcţiei tiroidiene; la vârsta de 3 luni anticorpii materni nu au mai fost detectaţi la sugari.

Discuţii: Tireotoxicoza la nou-născut constituie o urgenţă; tratamentul antitiroidian la mamă are un rol esenţial; dozele mari cresc riscul hipotiroidismului perinatal. Gravitatea simptomatologiei este dată de titrul de anticorpi (TSI) ce traversează placenta.

Concluzii: Monitorizarea nou-născutului provenit din mamă cu boala Graves este esenţială; ea trebuie începută din perioada intrauterină şi continuată până la vârsta de 3-6 luni. Menţinerea eutiroidiei atât la mamă, cât şi la nou-născut este dificil de obţinut şi necesită o colaborare interdisciplinară.

Early sexual development

Corina Duncescu, Monica Marazan, Adela Chirita-Emandi, Ramona Stroescu and Ioana Micle

ABSTRACT

Puberty is a biological process that involves major physical and psychological changes at the end of which the child becomes an adult. Clinically, the onset of puberty is announced by the appearance of secondary sexual character that develops specific females, respectively to form the adult male, going through the five stages described by Tanner. The onset of puberty varies by race, ethnicity, geographic location, environmental and nutritional conditions, in the Caucasian population ranging from 8 to 12 years. Early sexual development is arbitrarily defined as the occurrence of secondary sexual characteristics before age 8 in girls and before age 9 in boys, respectively. Precocious puberty is classified into three broad categories: (1) gonadotropin dependent precocious puberty (central), (2) gonadotropin independent precocious puberty (peripheral), (3) partial precocious puberty. This paper aims to present the particular appearance of secondary sexual characteristics, the hormonal changes and the therapeutic possibilities of each category. Close follow-up of children, detailed medical history, chronological record of pubertal signs, repeated anthropometric and hormonal measurement are the key to a correct diagnosis and an early and effective treatment.

DEZVOLTAREA SEXUALA PRECOCE

Corina Duncescu, Monica Marazan, Adela Chirita-Emandi, Ramona Stroescu and Ioana Micle

REZUMAT

Pubertatea este un proces biologic ce presupune modificări fizice şi psihologice majore, la finele căruia copilul devine adult. Clinic, debutul pubertăţii este anunţat de apariţia caracterelor sexuale secundare ce evoluează specific pentru sexul feminin, respectiv masculin până la forma adultă, trecând prin cele 5 stadii descrise de Tanner. Debutul pubertăţii variază în funcţie de rasă, etnie, localizarea geografică, condiţii de mediu şi nutriţionale, la populaţia caucaziană situându-se între 8 şi 12 ani. Dezvoltarea sexuală precoce este definită arbitrar ca apariţia caracterelor sexuale secundare înainte de vârsta de 8 ani la fete, respectiv înainte de 9 ani la băieţi. Pubertatea precoce se clasifică în 3 categorii mari: (1) pubertatea precoce gonadodropin dependentă (centrală), (2) pubertatea precoce gonadotropin independentă (periferică), (3) pubertatea precoce parţială. Lucrarea de faţă îşi propune să prezinte sintetic, pentru fiecare categorie în parte, modul specific de apariţie a caracterelor sexuale secundare, modificările hormonale şi posibilităţile terapeutice. Urmărirea copiilor longitudinal, anamneza amănunţită, înregistrarea cronologică a semnelor pubertare, măsurătorile somatometrice şi investigaţiile hormonale repetate reprezintă cheia unui diagnostic corect şi premisa unui tratament precoce şi eficient.

Persistent severe hypoglycemia due to growth hormone deficiency

Corina Duncescu, Monica Marazan, Adela Chirita-Emandi, Ramona Stroescu and Ioana Micle

ABSTRACT

Introduction. In children, persistent hypoglycemia has a major negative impact on structural and functional brain development. In infants, hypoglycemia may be the presenting feature of growth hormone (GH) deficiency.

Aim. We present the outcome of GH substitution in a girl with persistent severe hypoglycemia since infancy.

Material and methods. The child was admitted in our clinic at age three in order to establish the etiology and proper treatment of the hypoglycemia. We assessed growth, as well as the biological and hormonal profile, until the presentation in our clinic. In addition to anthropometric measurements, we obtained repeated metabolic and hormonal serum tests, a GH stimulation test with arginine, bone age X-ray. Interpreting the results was difficult considering the long time treatment with prednisone (2 years and 6 months), started at the onset of the hypoglycemia.

Results. We established that the persistent severe hypoglycemia was due to GH deficiency and started recombinant human growth hormone (rhGH) substitution. The outcome was spectacular in terms of symptoms, anthropometric, biological and hormonal profile.

Conclusions. The etiologic diagnosis of persistent severe hypoglycemia is difficult and requires an extensive approach. In this case, the certainty of the diagnosis was established by the spectacular outcome on rhGH substitution.

HIPOGLICEMIA SEVERA PERSISTENTA PRIN DEFICIT DE HORMON DE CRESTERE

Corina Duncescu, Monica Marazan, Adela Chirita-Emandi, Ramona Stroescu and Ioana Micle

REZUMAT

Introducere. În copilărie, hipoglicemia persistentă are un impact negativ major asupra dezvoltării structurale şi funcţionale a creierului. În perioada de sugar, hipoglicemia poate fi forma de prezentare a deficitului de hormon de creştere (GH).

Scop. Prezentarea evoluţiei sub tratament substitutiv cu GH în cazul unei fetiţe cu hipoglicemie severă persistentă din perioada de sugar.

Material şi metodă. Copilul se internează în clinica noastră la 3 ani în vederea stabilirii etiologiei şi tratamentului hipoglicemiilor. Am realizat profilul somatometric, biologic şi hormonal până în momentul prezentării în clinica noastră. Pe lângă somatometrie, am obţinut determinări sanguine metabolice şi hormonale repetate, testul de stimulare a secreţiei de GH cu arginină, radiografie de vârstă osoasă. Interpretarea rezultatelor a fost îngreunată de tratamentul cu Prednison „a la longue“ (2 ani şi 6 luni), instituit la debutul hipoglicemiilor.

Rezultate. Am stabilit diagnosticul de hipoglicemie severă persistentă prin deficit de GH şi am instituit tratamentul substitutiv. Evoluţia a fost spectaculoasă atât din punct de vedere al simptomatologiei, cât şi somatometric, biologic şi hormonal.

Concluzii. Managementul unui copil cu hipoglicemie severă persistentă este dificil şi impune o abordare complexă. În cazul de faţă, certitudinea diagnostică a venit odată cu evoluţia spectaculoasă sub tratament substitutiv cu hormon de creştere uman recombinat.

Adrenal rest tumours in an adolescent with congenital adrenal hyperplasia – one year follow-up

Adela Chiriţă, Ramona Cojocaru, Monica Marazan, Corina Duncescu, Ramona Stroescu, Bogdana Zoica and Ioana Micle

ABSTRACT

Congenital adrenal hyperplasia (CAH) is an inherited disorder resulting in impaired production of cortisol and aldosterone. Male patients with CAH may present testicular adrenal rest tumours (TART).

Aim. To discuss the embryological, clinical features and treatment options of TART in a patient with CAH.

Case report. We present a case of TART in a 16 years and 6 months adolescent with salt-wasting type of CAH. The patient had periodic clinical evaluations, complete metabolic and endocrinological profile which guided the treatment. He was diagnosed at 6 weeks, when he begun substitution treatment with hydrocortisone. He was a compliant patient until age 14 years and 8 months, when he started high school and moved from home. At the age of 15 years and 6 months the clinical exam showed bilateral testis enlargement. The scrotal ultrasound sowed bilateral non-homogeneous, extensive masses. Hormone profile revealed increased ACTH and 17-OHprogesterone levels. Treatment was made by changing the night dose of hydrocortisone into dexamethasone to prolong ACTH suppression. After one year of treatment the testicular masses underwent important volume decrease.

Conclusions. Puberty has a negative impact on treatment compliance, so increasing the risk for TART. They are not malignant, but can result in gonadal dysfunction and infertility. It is important to screen for these tumours in CAH patients, to inform, discuss and offer cryopreservation of semen as soon as possible.

TUMORI ADRENOTESTICULARE LA UN ADOLESCENT CU SINDROM ADRENOGENITAL – REZULTATE DUPA UN AN

Adela Chiriţă, Ramona Cojocaru, Monica Marazan, Corina Duncescu, Ramona Stroescu, Bogdana Zoica and Ioana Micle

REZUMAT

Introducere. Sindromul adrenogenital este o boală genetică care are ca rezultat producţia scăzută de cortizol şi aldosteron. Pacienţii de sex masculin cu sindrom adrenogenital pot prezenta tumori adrenotesticulare.

Scop. Discutarea caracteristicilor embriologice, clinice şi opţiunilor terapeutice la un adolescent cu sindrom adrenogenital, formă completă.

Prezentarea cazului. Prezentăm un adolescent de 16 ani şi 6 luni cu sindrom adrenogenital, cu pierdere de sare. A fost diagnosticat la 6 săptămâni, când a început tratamentul de substituţie cu hidrocortizon. Pentru adaptarea periodică a tratamentului, pacientul a efectuat evaluări clinice, metabolice şi endocrine complete. Datorită suportului familial, a fost un pacient compliant până la vârsta de 14 ani şi 8 luni, când a început liceul şi s-a mutat de acasă. La vârsta de 15 ani şi 6 luni, clinic, se observă creşterea în volum a testiculelor. Ecografia testiculară confirmă mase tumorale extinse, neomogene, bilaterale. Profilul hormonal relevă ACTH şi 17-OH progesteron crescute. Tratamentul a fost realizat prin înlocuirea dozei de noapte de hidrocortizon cu dexametazonă, pentru a prelungi suprimarea ACTH. După un an de tratament, tumorile testiculare au scăzut substanţial în volum.

Concluzii. Pubertatea are un impact negativ asupra complianţei la tratament, crescând astfel riscul de tumori adrenotesticulare. Acestea nu sunt maligne, dar pot duce la disfuncţie gonadală şi infertilitate. Este important să se efectueze screening-ul acestor tumori la pacienţii cu sindrom adrenogenital.

Indicele intimă medie carotidian (IMc) este un cunoscut marker subclinic pentru ateroscleroză. Fenomenul de recuperare nutriţională la copiii născuţi mici pentru vârsta gestaţională (SGA) a fost asociat cu obezitate precoce şi cu riscul dezvoltării sindromului metabolic.

Scop. De a determina dacă există o asociere între SGA şi IMc; de a stabili valori prag ale IMc la copiii obezi.

Material şi metodă. Studiul prospectiv a fost derulat pe o perioadă de un an (iulie 2012 – iunie 2013). Au fost analizaţi 122 de pacienţi cu obezitate, 96 de pacienţi născuţi cu greutate normală pentru naştere (AGA) şi 26 de pacienţi născuţi cu greutate mică pentru naştere (SGA). Ambele loturi au fost omogene din punct de vedere al vârstei, sexului şi indicelui de masă corporală (IMC). Folosind curba ROC au fost stabilite valori prag pentru ambele grupe. IMc a fost semnificativ mai crescut la lotul SGA (p = 0,0035). Valoarea prag de 0,049 cm pentru IMc a fost obţinută la ambele loturi, cumulat, cu o specificitate şi sensibilitate crescută.

Concluzii. Copiii născuţi SGA se asociază cu risc aterosclerotic. IMc este un cunoscut marker subclinic pentru ateroscleroză, fiind o metodă ieftină şi noninvazivă. Studii populaţionale extinse sunt necesare în vederea stabilirii unor valori prag în ceea ce priveşte IMc.

COMMON CAROTID INTIMA MEDIA THICKNESS IN OBESE CHILDREN BORN SMALL FOR GESTATIONAL AGE VERSUS APPROPRIATE FOR GESTATIONAL AGE

Ramona Stroescu, Ioana Micle, Teofana Bizerea, Monica Marazan, Maria Puiu, Gabriela Doros and Otilia Marginean

ABSTRACT

The intima media thickness of the common carotid artery (CIMT) is a well-known marker of subclinical atherosclerosis. The “catch-up growth” phenomenon in children born small for gestational age (SGA) has been linked to early onset obesity with the subsequent emergence of metabolic syndrome (MetS). Aim: to determine the association between being born SGA and CIMT, a measure of atherogenesis and to establish cut off values for CIMT in obese children.

Material and methods. A prospective study was carried out over a 1 year period (Jul 2012-June 2013). We analyzed 122 obese patients, 96 patients appropriate for gestational age (AGA) and 26 patients SGA. Both groups were matched for age, sex and BMI. CIMT was measured in all the patients. Using ROC curve, cut off values have been obtained for both groups.

Results. CIMT in obese children born SGA was significantly increased as compared with obese children born AGA similar age, sex and BMI (p = 0.0035). A CIMT cut off value of 0.049 cm has been obtained with a high sensitivity and specificity.

Conclusion. Being born SGA increases the atherogenic risk. CIMT is a well-known marker of subclinical atherosclerosis and is a noninvasive and inexpensive method for detecting development of subclinical atherosclerosis. Further population studies regarding reference values for CIMT in obese children born SGA and AGA are necessary

Keywords: small for gestational age, obesity, intima media thickness of the common carotid artery
