Abstract:
Objective To explore the effect and compare the relapse rates of 1-desamino-8-D-Arginine Vasopressin(DDAVP) different withdrawal ways after initial 3 months in primary monosymptomatic nocturnal enuresis(PMNE) patients,in order to provide some evidences and references to use DDAVP to cure PMNE preferably.Methods Two hundred and fifty-six cases PMNE patients who were treated in Hubei Maternal and Child Health Hospital from November 2014 to June 2016 were selected and randomly divided into group A (DDAVP immediate withdrawal group,65 cases),group B(DDAVP day reduction group,58 cases) and group C (DDAVP step reduction group,60 cases).All patients were given DDAVP tables for 3 months.After 3 months for DDAVP,patients who were effective (full respond and partial respond) to DDAVP continued to undergo a withdrawal stage,those in group A underwent immediate cessation,those in group B continued to receive the effective dose every other day for 2 months and those in group C were step by step tapered by 0.05-0.10 mg every 2-4 weeks until completely stopped,the period was not more than 3 months.All patients had a follow-up visit for 3 months after cessation of DDAVP.Results A total of 183 patients completed the study finally,there were 65 patients in group A,58 patients in group B and 60 patients in group C.Initial 3 months the effective rates of group A,B and C were respectively 89.23％ (58/65),89.66％ (52/58) and 86.67％ (52/60),there were not statistically significant difference(x2 =0.309,P =0.857).There were 58 patients in group A,52 patients in group B and 52 patients in group C continued to undergo the withdrawal stage.One month after cessation of DDAVP,the effective rates of group B (88.46％,46/52) and group C (92.31％,48/52) were significantly higher than group A(67.24％,39/58) (x2 =7.030,P=0.008;x2 =10.417,P=0.001),while the relapse rates of group B(19.23％,10/52) and group C(17.31％,9/52) were significantly less than group A(36.21％,21/58) (x2=3.904,P=0.048;x2=4.937,P =0.026).Three months after cessation of DDAVP,the effective rates of group C (78.85％,41/52) were significantly higher than group A (50.00％,29/58) and group B (57.69％,30/52) (x2 =9.859,P=0.002;x2 =5.371,P=0.020),and the relapse rates of group C(32.69％,17/52) were significantly less than group A (55.17％,32/58) and group B (51.92％,27/52) (x2 =5.609,P =0.018;x2 =3.939,P =0.047),while the effective rates and relapse rates were not statistically significant difference between group A and group B(x2 =0.652,P =0.419;x2 =0.116,P =0.733).Severe adverse events related to DDAVP were not observed in any patients.Conclusion Gradual withdrawal after initial 3 months of DDAVP may improve the effect and reduce the relapse rates,the short-term and long-term curative effects of step-by-step withdrawal treatment are both well,while long-term curative effects of every other day withdrawal treatment is not obviously well.
