• OBJETIVO: Determinar a variação da CPK sérica em função do TSH e T4 livre (FT4) e avaliar a CPK sérica nos estados patológicos da tireoide (hipertireoidismo e hipotireoidismo), em relação ao eutireoidismo. MATERIAIS E MÉTODOS: Analisaram-se, retrospectivamente, 6.230 exames laboratoriais de 2007 a 2011, com as dosagens de TSH e CPK. Destas, 3.369 com dosagens de FT4. Avaliou-se a correlação entre CPK com TSH e com os estados patológicos da tireoide. RESULTADOS: A correlação entre TSH e CPK foi positiva (r = 0,065), enquanto entre CPK e FT4 foi inversamente proporcional (r = -0,091, p < 0,05). Do total, 586 (9,4%) medidas foram de hipertireoidismo com mediana (intervalo) do CPK de 98 U/L (27 a 1.113) e 556 (8,9%), hipotireóideos com CPK de 114 U/L (25-4.182). CONCLUSÃO: Houve correlação positiva entre CPK sérica e TSH e negativa com FT4, sendo a CPK menor no grupo com hipertireoidismo e maior no grupo de hipotireoidismo. OBJECTIVE: To determine serum CPK variation based on TSH e free T4 (FT4), and to assess serum CPK in pathological states of the thyroid (hyperthyroidism and hypothyroidism), in relation to the euthyroidism. MATERIAL AND METHODS: We evaluated retrospectively 6,230 laboratory results of TSH and CPK from 2007 to 2011. From these, 3,369 had free T4 results. We evaluated the correlation between CPK and TSH and the pathological states of the thyroid. RESULTS: The correlation between TSH and CPK was positive (r = 0.065), while that between CPK and FT4 was negative (r = -0.091, p < 0.05). From the total of results analyzed, 586 (9.4%) were measures of hyperthyroidism, with a median (range) of CPK of 98 U/L (27 to 1,113), and 556 (8.9%) were of hypothyroidism, with CPK of 114 U/L (25-4,182). CONCLUSION: A positive correlation was found between serum CPK and TSH, and a negative correlation between CPK and FT4. CPK was lower in the group with hyperthyroidism, and greater in that with hypothyroidism.
