Lipid storage myopathies. A review of metabolic defect and of treatment.

Various cases of lipid storage myopathies have been described. The biochemical defect could be determined in only some of these cases. The syndromes identified to date are as follows: carnitine deficiency (type I lipid storage myopathy), carnitine-palmityltransferase (CPT) deficiency and pyruvate-decarboxylase deficiency. In the last two diseases the vacuolization in muscle is not marked. The case of a 10 year old carnitine deficient patient with a history of insidious muscle weakness in the proximal limb and neck muscles is presented. The patient was treated with oral carnitine and a medium chain triglyceride diet for 18 months and her clinical status has remained improved. In other lipid storage patients prednisone treatment resulted in improvement. In cases of suspected lipid storage myopathy the following studies are indicated: 1) examination of ketone bodies in serum and urine during fasting, long chain and medium chain triglyceride diets; 2) serum triglyceride and serum carnitine; 3) study on fresh muscle and fibroblasts with labeled substrates, biochemical determination of carnitine and CPT in muscle.

[Benign muscular dystrophy with hypergonadotrophic hypogonadism and congenital cataract].

A syndrome characterized by benig muscular dystrophy, hypergonadotropic hypogonadism, congenital cataract and normal karyotype is reported. A similar condition was described by Bassöe. The patient's family tree revealed a number of isolated cases presenting some component of the syndrome, suggesting that this is connected with a recessive autosomic gene, probably with pleiotropic effect. The muscular disorder was absent in most of the other family members and its clinical signs were probably favoured by the low plasma level of testosterone with consequent reduced myotrophic action. The simultaneous presence of congenital cataract links the syndrome on the one hand to Steinert's myotonic dystrophy, although there were no clinical or electromyographic signs of myotonia, and on the other to other hereditary or familial neuroectodermal syndromes, compared to which it presents specific differential traits.

Carnitine deficiency of skeletal muscle: report of a treated case.

We studied a 10-year-old girl with an insidious muscle disease beginning at age 7. Muscle biopsy showed that the majority of type I fibers were vacuolated and contained lipid excess. Carnitine deficiency was found in skeletal muscle. The patient was treated with 3.0 gm L-carnitine per day and with a medium-chain triglyceride diet. She showed a rapid improvement and recovery of strength. A muscle biopsy 8 months later showed a decreased lipid content. Oral carnitine replacement represents an effective treatment for the disease.

Carnitine deficiency of human skeletal muscle with associated lipid storage myopathy: a new syndrome.

In a rare myopathy muscle fibers contained myriad lipid-filled vacuoles. Homogenates of the patient's muscle oxidized fatty acids more slowly than normal (11 controls). Addition of carnitine increased the oxidation rate with the patient's muscle to the level attained by the controls with carnitine. In five separate muscle samples from the patient the mean carnitine level was less than 20 percent of that observed in 42 controls. Carnitine palmityl transferase and palmityl thiokinase levels in the patient's muscles were not depressed. The present case represents the first recognized instance of carnitine deficiency in human skeletal muscle.
