Repeated and excessive consumption of alcohol leads to pathophysiologi
cal disorders in skeletal muscles. A successful management of this syn
drome requires a strict abstinence and a nutritionally adequate diet.
We propose here a simple and noninvasive investigation using P-31 magn
etic resonance spectroscopy (MRS) to monitor the recovery of the basal
energy status of eminence thenar muscles from documented chronic alco
holic patients during a controlled 15-day period of abstinence. Cessat
ion of alcohol abuse induced a significant recovery of the PCr/(PCr P-i) ratio otherwise depressed before the abstinence. On the contrary,
the relative level of free inorganic phosphate decreased, whereas int
racellular pH was not affected. These results demonstrate (a) the rapi
d improvement of basal muscular energy metabolism during abstinence fo
r patients with a chronic and heavy alcohol consumption, and (b) the f
easibility of a follow-up of this recovery by serial examinations usin
g P-31 MRS.
