RESUMO
OBJECTIVE: Primary hypothyroidism is common in the elderly. Yet its care remains unclear. PATIENTS AND METHODS: Clinical, biological characteristics and outcome of 45 patients aged over 60 years admitted for in-hospital initiation of treatment for primary hypothyroidism were recorded. Causes and tolerance of treatment (clinical and ECG monitoring in hospital) were seek for. RESULTS: Initial symptoms, predominantly fatigue (84.4%), were moderate, contrasting with severe biological hormonal deficiency. The most common routine biological change was hypercholesterolemia (57.6%). Female predominance was obvious (77.8%) and the most usual aetiology autoimmune chronic thyroiditis. Despite variability of symptoms, long term follow-up demonstrates a positive response to treatment, including an improvement in fatigue, eye-lid swelling, bradycardia and overweight. This clinical improvement was achieved on an average dose of 1.22 +/- 0.47 mg/kg/day L-T4 in order to maintain normal TSH (3.76 +/- 2.93 mUI/l). Cardiovascular incidents while starting treatment require experienced care and low dose initial treatment. CONCLUSION: Primary hypothyroidism is still lately discovered in the elderly. Yet, since treatment is efficacious and simple, the disease should be searched for and cared after whenever a related symptom occurs.
