“…Those with "systemic carnitine deficiency" had recurrent episodes of hypoglycemic, hypoketotic encephalopathy or "Reyelike" syndrome beginning in infancy or early childhood and low concentrations of carnitine in serum, muscle, and liver. Patients with "myopathic carnitine deficiency" had progressive lipid storage myopathy beginning in childhood or later in life, and carnitine deficiency was confined to skeletal muscle (3)(4)(5). However, recently, it has become apparent that many of these cases were, in fact, due to a variety of defects involving P-oxidation or the respiratory chain with secondary carnitine deficiency (6).…”

“…CPT II deficiency (OMIM 600650) is the most common, though rare, autosomal recessive inherited disorder of the fatty acid β-oxydation cycle with a widely heterogeneous phenotype and different clinical pictures: the result is the accumulation of long chain acylcarnitine in the mitochondrial matrix [6]. This enzyme deficiency has also resulted the most frequent associated disorder in a series of 36 patients with idiopathic myoglobinuria [7].…”

“…Objawy pierwotnego mięśniowego niedoboru karnityny postępują powoli i zwykle rozpoczynają się w dzieciństwie, choć zdaniem niektórych badaczy występują jeszcze później, tzn. w drugiej lub trzeciej dekadzie życia [21,54,55]. U tych chorych charakterystycznymi objawami są postępujące proksymalne osłabienie mięśni kończyn, tułowia i twarzy często o zmiennym przebiegu.…”

“…Dodatkowo w tym typie zaburzeń transportu karnityny poziom kinazy kreatyninowej może być zwiększony w osoczu, a w badaniu elektromiograficznym występują cechy miopatii. Należy pamiętać, że stosowanie suplementacji L-karnityny nie uzupełnia jej braku w mięśniach [21,55]. W tej postaci zazwyczaj podaje się L-karnitynę doustnie w dawce 2-6 gramów na dzień.…”
