Objective: To determine the prevalence of muscle cramps in subjects wi
th chronic liver disease and to identify factors associated with their
development, Methods: We performed a cross-sectional survey in 132 su
bjects with chronic liver disease: cirrhotics (n = 92) and subjects wi
th chronic hepatitis (n = 40), In addition, to control for diuretic us
e, patients with congestive heart failure (n = 40) were included as a
comparison group, Results: The prevalence of chronic muscle cramps was
significantly greater in cirrhotics compared with patients with chron
ic hepatitis [48/92 (52%) vs 3/40 (7.5%), respectively, p < 0.0001] an
d compared with subjects with congestive heart failure [8/40 (20%), p
< 0.001]. Factors, including age, gender, alcoholic liver disease, ele
ctrolytes, and diuretic use were similar among cirrhotics with and wit
hout cramps, Significantly higher total bilirubin and lower albumin le
vels were noted in cirrhotics with and without cramps, respectively; h
owever, there was no significant difference in Child's A or B classifi
cation, Conclusions: There is an increased prevalence of chronic muscl
e cramps in subjects with cirrhosis that appears to be independent of
the etiology of cirrhosis, diuretic consumption, serum electrolyte alt
erations, or differences in Child's classification, These results sugg
est that cramps in these patients are related specifically to the deve
lopment of cirrhosis, and worsening liver function may be a risk facto
r for the development of cramps.
