Background
Administration of diuretics and the presence of ascites in patients with cirrhosis were reported to be associated with muscle cramps; however, the clinical evidence is limited. This study aimed to determine whether muscle cramps are a diuretic-induced complication and whether ascites was a factor related to muscle cramp.
Methods
A total of 1064 adult patients with cirrhosis were enrolled from 10 hospitals in Japan between June 2017 and December 2018. A questionnaire regarding cramps was completed by all patients. The ratio of extracellular water (ECW) was analyzed using the bioelectrical impedance analysis. Logistic regression analysis was performed to analyze the effects of diuretic administration and the ECW ratio on cramps.
Results
Patients using diuretics had a higher incidence rate, higher frequency, stronger pain, and longer duration of cramps than those who did not. In the multivariate analysis, diuretic administration and the ECW ratio values ≥ 0.4 were not significantly associated with the presence, frequency, intensity, or duration of cramps. However, in the case of patients limited to Child–Pugh B or C, diuretic use was significantly correlated with the cramp frequency.
Conclusions
These results demonstrated that muscle cramps were not a complication of diuretic use in patients with cirrhosis; however, in those limited to Child–Pugh B or C, diuretic use was a factor that affected the frequency of cramps. Moreover, no association was found between the presence of ascites and cramps.
