Abstract:
Objective To clarify the clinical features,therapeutic strategy and prognosis of lipid storage myopathy (LSM).Methods The clinical data and therapeutic effects of 42 LSM patients were summarized retrospectively.All patients were followed up to evaluate their prognosis.Results Data of short-term therapeutic results of all the 42 patients were available.Thirty-three cases were placed in low- doses prednisone and 9 cases in riboflavin.All patients showed marked and quick improvement of symptoms within one month.Among thirty-two patients followed up for more than one year,26 cases had a full recovery and 6 remained to have intolerance to heavy exercise.Thirteen patients had relapses of muscle weakness in various degrees and most of which were induced by exertion,exposure to coldness and upper respiratory tract infection.In 5 patients the symptoms were recurred for more than one time.Among 13 cases with relapses, 7 had family history.Conclusions Our data suggest that LSM is a treatable disease and well responsive to low-doses prednisone.The disease tends to recur,especially in patients with family history.Glutaric aciduria type Ⅱ should be considered in LSM patients who are responsive well to riboflavin,indicating drug therapeutic strategy for LSM should be based on the etiology of the disease.
