Aim: Pruritus is a common comorbidity in chronic liver disease. The aim of this study was to clarify the prevalence of pruritus and its characteristics in patients with chronic liver disease. Methods: A total of 1631 patients with chronic liver disease who attended one of nine joint-research facilities from January to June 2016 were enrolled. We investigated the prevalence of pruritus, itch location, itch duration, daily itch fluctuation, seasonal itch exacerbation, treatment drugs, and therapeutic effects using a medical interview questionnaire. Results: The median age was 66 years and 890 (54.6%) patients were women. The prevalence of pruritus was 40.3% (658/1631), and it differed according to the underlying liver disease. The most frequent body location for pruritus was on the back (63.1%). Pruritus duration was more than 6 months in 252 (38.3%) patients. The severity of pruritus, assessed using a visual analog scale, was higher during the day than at night (median, 4 vs. 3, P < 0.001). Seasonal exacerbation was observed in 296 (45.0%) patients. Although 301 (45.7%) patients were treated with antipruritic agents, 57.8% (174/301) patients reported an insufficient effect. Active hepatitis B virus infection (odds ratio [OR], 2.51; P = 0.043), primary biliary cholangitis (OR, 3.69; P = 0.018), diabetes (OR, 1.57; P = 0.010), and aspartate aminotransferase >= 60 U/L (OR, 2.06; P = 0.011) were independent factors associated with pruritus. Conclusion: The prevalence of pruritus varies according to the chronic liver disease etiology. Underlying liver disease, aspartate aminotransferase >= 60 U/L, and comorbid diabetes are factors associated with pruritus in patients with chronic liver disease.
