Effect analysis of α-lipoic acid combined with alprostadil in patients with diabetic peripheral neuropathy / 中国综合临床

ABSTRACT

Objective To discuss the effect of α-lipoic acid combined with alprostadil in patients with diabetic peripheral neuropathy (DPN).Methods Eighty-two patients with DPN were divided into the control group(n=41) and research group(n=41) according to the random number table method.The patients of the control group were given alprostadil based on conventional therapy, while the research group were given alpha lipoic acid based on treatment of the control group, the course was two weeks.The bilateral median nerve and sural nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) were tested by electromyograph.Disease severity were evaluated by neuropathy symptoms questionnaire (TSS) and pain degree were tested by Visual analogue scales(VAS).The MNCV, SNCV, TSS and VAS of before and after treatment and the clinical effect of the two groups were compared.Results There were no statistically significant difference about MNCV and SNCV of the two groups before treatment (P＞0.05).After treatment, the MNCV and SNCV of nervus medianus and nervus peroneus communis of research group and control group were significantly higher than before treatment, and the differences of research group before and after treatment (MNCV of nervus medianus (42.5 ± 3.6) m/s vs (47.8± 4.6) m/s, t =-5.752, P ＜ 0.05;SNCV of ervus medianus (39.6 ±1.6) m/s vs (46.2±4.5) m/s,t =-5.882,P＜0.05;MNCV of nervus peroneus communis (39.8±3.2) m/s vs (44.5±2.5) m/s,t=-4.263,P＜0.05;SNCV of nervus peroneus communis (36.5±1.7) m/s vs (48.7± 2.6) m/s, t =-7.526, P ＜ 0.05), significantly obvious than the control group (MNCV of nervus medianus (42.3 ±4.2) m/s vs (44.5±5.3) m/s,t =-4.627,P＜0.05;SNCV of nervus medianus (39.8 ±2.4) m/s vs (42.4±2.5) m/s,t =-5.527,P＜0.05;MNCV of nervus peroneus communis (40.3±1.6) m/s vs (42.2± 1.6) m/s, t =-4.181, P＜ 0.05;SNCV of nervus peroneus communis (36.4± 2.3) m/s vs (41.2±3.5) m/s,t =-5.928,P＜0.05).Before the treatment,the TSS and VAS of the control group were (11.4±2.5) sore and (5.3±1.6) sore,of the research group were (11.6±1.6) sore and (5.2±1.8) sore,and there was no significant difference between the two groups (P＞0.05).After treatment, the TSS and VAS of the control group were (6.4± 1.3) sore and (3.6± 1.3) sore, of the research group were (4.2± 3.3) sore and (1.7 ±0.9) sore, and compared to before treatment, there was significant difference (P＜0.05), and the research group was significantly lower than the control group, the difference between the two groups was statistically significant (P＜ 0.05).The total effective rate of research group was obviously higher than that of control group, the differences were statistically significant (95.1％ (39/41) vs 65.9％ (27/41), x2 =5.363, P =0.031) .Conclusion The effect of α-lipoic acid combined with alprostadil in patients with diabetic peripheral neuropathy is obviously better than that of using alprostadil only,it is worth popularization and application.
