Study on the efficacy of ganciclovir in viral keratitis and its influence on serum related indicators / 中国医师杂志

ABSTRACT

Objective To investigate the efficacy of ganciclovir in viral keratitis and its influence on serum related indicators.Methods Patients with viral keratitis from May 2012 to December 2013 in our hospital were randomly divided into control and observation groups, each group had 62 cases.Patients in control group were treated with acyclovir eye drops, and those in observation group were treated with ganci-clovir ophthalmic gel.The difference in efficacy of two groups was compared.The levels of serum inflamma-tory cytokines of interleukin-2 (IL-2), IL-4, IL-6, IL-8, tumor necrosis factor-α(TNF-α), and interferon-γ( IFN-γ) of two groups before and after treatment were compared, the serum levels of nitric oxide ( NO) , super oxide dismutase (SOD), malondialdehyde (MDA), C3, and C-reactive protein (CRP) were been compared.Results The pain relief time and corneal healing time of observation group [(3.41 ±0.89)d and (4.02 ±1.11)d] were all shorter than control group [(4.52 ±1.21)d and (6.30 ±1.45)d].The cure rate and total effective rate of observation group were 58.06%and 90.32%, respectively.It was sig-nificantly higher than control group ( P <0.05).After 3 and 7 days of treatment, the serum levels of IL-4, IL-6, and IL-8 were lower than control group, and IL-2, and IFN-γwere higher than control group (33.87%and 82.26%) ( P <0.05).After 3 and 7 days of treatment, the serum levels of NO and MDA were lower than control group, and SOD, C3, and CRP were higher than control group ( P <0.05).Con-clusions Ganciclovir has a better efficacy than acyclovir for viral keratitis, and can effectively adjust the serum levels of related indicators.
