ABSTRACT

INTRODUCTION:

Autoimmune thyroid diseases are reported in no treated hepatitis C virus (HCV) infection. The standard interferon alpha (IFNΑ) treatment is associated with an increase of thyroid damage and dysfunction. The present cohort prospective study compared thyroid function and autoimmunity in HCV patients' monoinfected and coinfected HCV-HIV at baseline, during and after IFNΑ therapy.

METHODS:

We studied 790 HCV infected patients G1 (monoinfected HCV N = 580) and G2 (HCV-HIV coinfected N = 210). They were evaluated for thyroid function and thyroid tiroperoxidase antibodies (TPOAb) at baseline and 235 patients (G1 183; G2 52) post IFNΑ therapy. If thyroid dysfunction (TD) was diagnosed, they were reevaluated at 12 month after discontinuation to determine whether the TD was transitory or definitive.

RESULTS:

No difference was found in the prevalence of TD at baseline in G1 (7.6%) and G2 (9%). However, monoinfected patients showed a higher prevalence of TPOAb positivity with a women preponderance in this group. There was no difference in TD between both groups during IFNΑ therapy (G1 23.5% vs G2 19.2%). In G1 the autoimmune TD was higher than in G2 (67.4% vs 30%, p = 0.02). Autoimmune TD during IFNΑ tended to evolve to definitive hypothyroidism and non-autoimmune TD recovered euthyroidism after IFN #913; discontinuation. The presence of positive TPOAb (RR 3.55) and female gender (RR 2.4) were associated with the development of TD with IFNΑ therapy.

CONCLUSIÓN:

Our hypothesis is the importance of HCV in G1 and G2, combined with IFNΑ in triggering TD and TPOAb positivity, not described in other diseases' applications
RESUMEN

INTRODUCCIÓN:

El presente estudio prospectivo de cohorte evaluó y comparó la función y la autoinmunidad tiroidea en pacientes con virus de la hepatitis C (VHC) monoinfectados y coinfectados con VHC-virus de la inmunodeficiencia humana (VIH) al inicio, durante y después de la terapia estándar con interferón alfa (IFNΑ).

MÉTODOS:

Se estudiaron 790 pacientes infectados por VHC G1 (VHC monoinfectados N = 580) y G2 (coinfección por VHC-VIH N = 210). Se evaluó la función tiroidea y los anticuerpos anti-tiroperoxidasa (ATPO) al inicio del estudio, y a 235 pacientes tratados con IFNΑ (G1 183; G2 52). Si se diagnosticó disfunción tiroidea (DT), estos fueron reevaluados 12 meses posteriores al tratamiento para determinar si esta era transitoria o definitiva.

RESULTADOS:

No se encontraron diferencias en la prevalencia de DT en forma basal G1 (7,6%) vs. G2 (9%). Los pacientes monoinfectados mostraron una mayor prevalencia de positividad de ATPO, siendo preponderante el sexo femenino en el G1. No hubo diferencias en la DT entre ambos grupos con IFNΑ (G1 23,5 vs. G2 19,2%). En G1, la DT autoinmune fue mayor que en G2 (67,4 vs. 30%; p = 0,02). La DT autoinmune con IFNΑ tendió a evolucionar hacia un hipotiroidismo definitivo, mientras que la DT no autoinmune fue transitoria. Tuvieron mayor riesgo de DT durante el tratamiento los pacientes que presentaban ATPO positivos previos (RR 3,55) y el sexo femenino (RR 2,4).

CONCLUSIONES:

Planteamos como hipótesis la importancia del VHC en G1 y G2, combinado con IFNΑ en el desarrollo de la DT y positividad de los ATPO, no descripta en su uso en otras enfermedades
