Double-blind controlled randomised study of lactulose and lignin hydrolysed combination in complex therapy of atopic dermatitis

Abstract

BackgroundAtopic dermatitis (AD) is an immune mediated disease with complex pathogenesis characterised by persistency, frequent exacerbations, and inefficacy of existing therapies. Damaged or weakened intestinal microbiocenosis is considered as an important aetiological factor of AD. The aim of this study was to evaluate the efficacy and safety of medical preparation Lactofiltrum (lactulose and sorbent (lignin hydrolysed)) in comparison with placebo in complex with standard therapy of AD.MethodsDouble-blind, placebo controlled, randomised comparative study of effectiveness and safety of 400 mg lactulose and 120 mg lignin hydrolysed combination as a part of standard combined AD treatment, conducted in parallel groups of patients aged 18–60.ResultsComparison of clinical efficacy of Lactofiltrum in combination with the standard treatment has been demonstrated by measuring the following parameters: administration of Lactofiltrum results in 1) distinct clinical improvement in 56.75% of patients, 2) decrease of the mean values of scoring atopic dermatitis (SCORAD) index in 71.94% of patients, 3) elimination of itching in 50% of patients, and 4) life quality improvement for 76.41%. In the placebo group, 1) distinct clinical improvement was observed in 20% of patients, 2) decrease in SCORAD index values observed by 56.98%, 3) itching relief in 15.56%, and 4) life quality improvement by 36.38%.ConclusionsClinical improvement and persistent termination of clinical symptoms provide evidence of effectiveness in use of Lactofiltrum combined with the standard treatment of AD.
