ABSTRACT
OBJECTIVES: Longer-acting gonadotropin-releasing hormone analogs (GnRHa) have been widely used for central precocious puberty (CPP) treatment. However, the follow-up of patients after this treatment are still scarce. Our aim was to describe anthropometric, metabolic, and reproductive follow-up of CPP patients after treatment with leuprorelin acetate 3-month depot (11.25 mg). METHODS: Twenty-two female patients with idiopathic CPP were treated with leuprorelin acetate 3-month depot (11.25 mg). Their medical records were retrospectively evaluated regarding clinical, hormonal, and imaging aspects before, during, and after GnRHa treatment until adult height (AH). RESULTS: At the diagnosis of CPP, the mean chronological age (CA) was 8.2 ± 1.13 year, and mean bone age (BA) was 10.4 ± 1.4 year. Mean height SDS at the start and the end of GnRHa treatment was 1.6 ± 0.8 and 1.3 ± 0.9, respectively. The mean duration of GnRHa treatment was 2.8 ± 0.8 year. Mean predicted adult heights (PAH) at the start and the end of GnRH treatment was 153.2 ± 8.6 and 164.4 ± 7.3 cm, respectively (p<0.05). The mean AH was 163.2 ± 6.2 cm (mean SDS: 0.1 ± 1). All patients were within their target height (TH) range. There was a decrease in the percentage of overweight and obesity from the diagnosis until AH (39-19% p>0.05). At the AH, the insulin resistance and high LDL levels were identified in 3/17 patients (17.6%) and 2/21 patients (9.5%), respectively. The mean CA of menarche was 12.2 ± 0.5 years. At the AH, PCOS was diagnosed in one patient (4.8%). CONCLUSIONS: Long-term anthropometric, metabolic, and reproductive follow-up of patients with CPP treated with longer-acting GnRHa revealed effectivity, safety, and favorable outcomes.

The incidence of polyneuropathy in patients with hypothyroidism is not precisely known, but some studies report that about 25% to 42% of patients may show neuropathic clinical signs. We report a case of autoimmune poliglandular syndrome type 2 (APS-2), whose initial presentation was hypothyroid polyneuropathy. A 41-year-old man complained of slowly progressive paresthesias and weakness affecting all four limbs, and associated with frequent drowsiness, weakness, cold intolerance, dizziness, nausea, and craving for salt. General physical examination showed hyperpigmentation of skin and mucous membranes, and hypotension. Neurological examination showed global, deep, and symmetrical hyporeflexia with slight signs of superficial hypoesthesia in the limbs. Electrodiagnostic studies (ENMG) together with laboratory tests, confirmed the suspicion of Hashimoto's thyroiditis associated with Addison's disease featuring the picture of APS-2. The patient was treated with fludrocortisone 0.05 mg/day and levothyroxine 100 mcg/day, and showed gradual and complete resolution of complaints. Changes were found in general physical and neurological examinations. ENMG repeated six months later showed complete resolution of neuropathy. This report shows a rare case of APS-2 presented as polyneuropathy hypothyroidism, and reinforces the importance of dosing thyroid hormone in polyneuropathy syndromes. Levothyroxine replacement was shown to be effective in reversing clinical and electrophysiologic neuropathy.

A incidência de polineuropatia em indivíduos com hipotireoidismo não é precisamente conhecida, mas alguns estudos relatam que cerca de 25% a 42% dos pacientes podem apresentar sinais clínicos neuropáticos. A seguir, relataremos um caso de síndrome poliglandular autoimune tipo 2 (SPA-2), cuja apresentação inicial foi uma polineuropatia hipotireóidea. Homem de 41 anos com queixas de parestesias e fraqueza lentamente progressiva acometendo os quatro membros associadas a sonolência frequente, astenia, intolerância ao frio, vertigens, náuseas e avidez por sal. O exame físico geral evidenciava hiperpigmentação de pele e mucosas, além de hipotensão. O exame neurológico demonstrou apenas hiporreflexia profunda global e simétrica com discretos sinais de hipoestesia superficial em extremidades dos membros. O estudo eletroneuromiográfico (ENMG), juntamente com a avaliação laboratorial, confirmou a suspeita de tireoidite de Hashimoto associada à doença de Addison, caracterizando o quadro de SPA-2. O paciente foi tratado com fludrocortisona 0,05 mg/dia e levotiroxina 100 mcg/dia e apresentou resolução gradual e completa das queixas e das alterações encontradas nos exames físico geral e neurológico. O ENMG, repetido após seis meses, evidenciou resolução completa do quadro neuropático. Este relato mostra um caso raro de SPA-2 apresentando-se como uma polineuropatia hipotireóidea e reforça a relevância da dosagem de hormônios tireoideanos em síndromes polineuropáticas. A reposição de levotiroxina mostrou-se efetiva em reverter o quadro clínico e eletrofisiológico da neuropatia. .
