ABSTRACT
Objective To observe the effect of human immunoglobulin on elderly head and facial post herpetic neuralgia (PHN) and peripheral blood TNF-α.Methods One hundred and twenty-two inpatients with PHN aged ≥65 years old were selected and divided into the observation group (52 cases) and control group (70 cases) by the systematic sampling method.The control group was given the early conventional combined therapy,while on this basis the observation group was intravenously dripped by human immunoglobulin.The incidence rate of PHN and pain visual analog scale(VAS) score at 1,2,3 months after recovery discharge from hospital were recorded in the two groups.Other 20 healthy elderly people were selected as the healthy control group.The TNF-α level was determined in the two patients groups before and after treatment and in the healthy control group.Results The PHN occurrence rate at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group(P＜0.05);the VAS score after treatment and at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group (P＜0.05);serum TNF-α level after treatment in the observation group was significantly lower than that in the control group (P＜0.01),moreover which was close to the level in the healthy control group(P＞0.5).Conclusion Human immunoglobulin can reduce the PHN occurrence in the old people with head and facial herpes zoster and reduce the peripheral blood TNF-α level.
