RESUMEN

OBJECTIVES:

To evaluate the effects of GH replacement therapy (GHR) for 3 years on glycated haemoglobin (HbA1c) and on the presence of dysglycaemia at any time during follow-up in Spanish adult patients with growth hormone deficiency (GHD). Study

design:

A retrospective study of 41 patients with GHD was conducted using baseline and long-term data. Changes in HbA1c values during the first 3 years of GHR were studied in both the overall population and patients with or without dysglycaemia during follow-up. Dysglycaemia was defined as FPG ≥ 100 mg/dl and/or HbA1c ≥ 5.7%.

RESULTS:

Mean HbA1c value (5.4 ± 0.4% at baseline) increased during the first and second years of GHR (HbA1c5.5 ± 0.4%, p = 0.05, and 5.5 ± 0.4%, p = 0.006 respectively). This increase was not maintained during the third year (HbA1c 5.4 ± 0.3%, p = 0.107) of GHR. Twenty-eight patients (68.2%) had dysglycaemia during follow-up, 9 of them since baseline. In the 19 patients without baseline dysglycaemia, HbA1cincreased during the first year and remained stable in the next 2 years (mean HbA1c 5.2 ± 0.4% at baseline; 5.5 ± 0.4% at 1 year, p < 0.050; 5.4 ± 0.4% at 2 years, p = 0.004, and 5.4 ± 0.4% at 3 years, p = 0.016). In the 9 patients with baseline dysglycaemia, HbA1c did not significantly change during the 3 years of GHR therapy.

CONCLUSIONS:

HbA1c values increased during the first 2 years of GHR therapy. In patients with no dysglycaemia before treatment, HbA1c steadily increased over the 3 years. However, it did not change in patients with baseline dysglycaemia
ABSTRACT

OBJETIVO:

Evaluar, en una cohorte de pacientes españoles con déficit de GH (GHD), el efecto de 3 años de tratamiento sustitutivo con hormona de crecimiento (GHR) sobre la hemoglobina glicada (HbA1c) y la presencia de disglucemia en cualquier momento del seguimiento.

DISEÑO:

Estudio retrospectivo de 41 pacientes con GHD en GHR. Se analizaron los cambios durante los tres primeros años de GHR, en los valores de la HbA1c tanto en la población general como en los subgrupos de pacientes con y sin disglucemia durante el seguimiento. Se definió disglucemia como una glucemia basal ≥ 100 mg/dl y/o HbA1c ≥ 5,7%.

RESULTADOS:

La HbA1c media (inicialmente 5,4 ± 0,4%) aumentó durante el primer y segundo año de GHR (HbA1c5,5 ± 0,4%, p = 0,05 y 5,5 ± 0,4%, p = 0,006, respectivamente); esta tendencia no se mantuvo durante el tercer año (HbA1c 5,4 ± 0,3%, p = 0,107). Veintiocho pacientes (68,2%) presentaron disglucemia durante el seguimiento, 9 de ellos desde el inicio del seguimiento. En los 19 pacientes sin disglucemia basal, la HbA1c se incrementó durante el primer año, permaneciendo estable durante los siguientes dos años (HbA1c media basal 5,2 ± 0,4%, 1er año 5,5 ± 0,4%, p < 0,050; 2do año 5,4 ± 0,4% p = 0,004 y 3er año 5,4 ± 0,4% p = 0,016). En los 9 pacientes con disglucemia basal la HbA1c no cambió en forma significativa durante los 3 años de GHR.

CONCLUSIONES:

Los valores de HbA1c aumentaron durante los dos primeros años de GHR. En los pacientes sin disglucemia pre-tratamiento la HbA1c presentó un incremento continuo durante los tres años. Sin embargo, no cambió en aquellos pacientes con disglucemia basal
