Efficacy of polyethylene glycol combined with pranoprofen drops on dry eye in patients with Sj(o)gren's syndrome and effect in content of interleukin-6 and tumor necrosis factor-α in tears / 中华风湿病学杂志

ABSTRACT

Objective To investigate the efficacy of pranoprofen drops on dry eye of patients with Sj(o)gren's syndrome (SS).Methods This is a prospective study.Sixty-eight inpatients with dry eye in our hospital were randomly divided into the experimental and control groups.Right eyes were taken for the trial,with 34 cases in each group.The experimental group was given pranoprofen eye drops combined with polyethylene glycol eye drops.Eyes of the control group were given polyethylene glycol drops only.Corneal fluorescein staining (FL),tear film breakup time (BUT) and Schirmer test (SIT) were tested before treatment and 1,2,4 weeks after treatment by the same care giver.The levels of IL-6 and TNF-α in tears were detected by ELISA.Analysis of variance of repeated data and t test were used for statistical analysis.Results The difference of FL,BUT,SIT and content IL-6 and TNF-α in tears in the experimental group patients before treatment and 1,2,4 weeks after treatment were signifcant (F=4.65,7.53,6.43,9.96,10.87; P＜0.05),which were statistically significantly different between the experimental group and the control group patients (F=3.27,5.85,4.36,8.36,7.23; P＜0.05).One week after treatment and before treatment,the difference of BUT and SIT of the two groups was not statistically significant (P＞0.05),those of the 2 weeks after treatment were statistically significantly different [BUT of the experimental group was (11.1±2.5) s,BUT of the control group was (9.7±1.9) s,t=2.594 8,P＜0.05; the SIT of the experimental group was (7.3±1.7) mm,the SIT of the control group was (5.9±1.7) mm,t=3.571 8,P＜0.05].BUT of the two groups at 4 weeks after treatment was statistically significantly different [BUT of the experimental group was (14.4±2.8) s,BUT of the control group was (11.4±2.6) s,t=4.469 4,P＜0.05; the SIT of the experimental group was (9.9±2.1) mm,the SIT of the control group was (8.7±1.9) mm,t=2.568 0,P＜0.05].The difference of FL and IL-6 and TNF-α in tears pretreatment between the two groups was not statistically significant (P＞0.05).At week 1,2,4 after treatment,the differences between the two groups were statistically significant (tFL=4.173 9,3.190 7,4.072 6; tIL-6=2.131 5,2.316 4,5.310 1; tTNF-α=2.216 4,4.871 9,8.175 0; P＜0.05).No significant discomfort and side effects were observed in the two groups.Conclusion Pranoprofen drops can significantly improve symptoms of dry eye in patients with pSS,in particular,the repair of the cornea,may be related to the inhibition of the expression of ocular inflammatory cytokines IL-6 and TNF-α,and thus reduce the ocular surface inflammatory reaction.
