• Fatigue

  Cancer-related fatigue. Some cancer patients have low blood levels of L-carnitine, which might reduce energy and lead to fatigue. Some early research suggests that taking L-carnitine might improve fatigue in advanced cancer patients. [webmd.com]

The question remains of whether the male predominance is due to sex-related differences in exercise activities, an X-chromosomal modifier gene, or hormonal factors such as estrogen that seem to be a regulator of CPT. 17, 18 Diagnostic workup of exercise-induced [jamanetwork.com]

Workup of such patients includes measuring plasma amino acids and looking for succinylacetone on urine organic acid analysis. [genico.ch]

• Hypoketotic Hypoglycemia

  Affected individuals also have low blood sugar (hypoglycemia) and a low level of ketones, which are produced during the breakdown of fats and used for energy. Together these signs are called hypoketotic hypoglycemia. [medlineplus.gov]

  The disease is characterized by a severe fasting intolerance leading to metabolic derangements of hypoketotic hypoglycemia, resulting in coma and seizures, and hepatic encephalopathy leading to liver failure. [orpha.net]

Natural history without treatment Severe infantile form is often fatal. Natural history with treatment Even with treatment, the severe infantile form of CPT2 may be fatal. [newbornscreening.info]

Management and treatment Treatment is based on prevention of the fasting intolerance by providing carbohydrate calories during periods of febrile or gastrointestinal illness. [orpha.net]

Prognosis The myopathic form of CPT II has a good prognosis. The severe infantile form may lead to sudden death during infancy due, in general, to paroxysmal cardiac arrhythmias. [orpha.net]

In some of the more severe infantile forms, there is a very poor prognosis. [idph.state.il.us]

Coma – Muscle pain and weakness – Weak heart muscle – Irregular heart beat – Enlarged liver – Liver failure Myopathic Form – Muscle pain and weakness – Muscle tissue breakdown – Discolored urine (e.g. red/brown) – Kidney issues( e.g. kidney failure) PROGNOSIS [evolvegene.com]

What is the prognosis? If the enzyme is completely lost there is rapid progression of the condition leading to death in infancy. If some enzyme activity remains, little or no progression with normal strength between episodes. [mda.org.au]

Etiology Missense mutations in the CPT2 gene result in the infantile form of CPT II deficiency. Contrary to the adult myopathic form (see this term), no S113L mutations have ever been detected in the infantile form. [orpha.net]

Presence or absence of an anion gap (AG) can help to distinguish the underlying etiology. In general, with a pure or uncompensated metabolic acidosis, every 10 mEq/L fall in bicarbonate (HCO 3 ) results in an average pH fall of 0.15. [mhmedical.com]

The molecular etiologies of these syndromes have not been determined. In this investigation, we considered the hypothesis that these syndromes result from defective transport of carnitine into tissues, particularly skeletal muscle. [osti.gov]

[…] compared to the adult group. [17] This group concluded that both the type and location of CPT2 mutation in combination with at least one secondary genetic factor modulate the long-chain fatty acid flux and, therefore, the severity of the disease. [17] Pathophysiology [en.wikipedia.org]

The mechanism of this destabilizing effect and its pathophysiologic impact remain enigmatic. Acyl- l -carnitines with more than 10 carbons in the acyl side-chain stabilized the variant S113L against the temperature-induced inactivation. [ng.neurology.org]

The pathophysiology and molecular biology vary among different forms of SCID, however, the lack of T-cell and B-cell function is the common endpoint in all forms of SCID. [genico.ch]

This can prevent low blood sugar. It can also prevent the body using fats for energy. And you should stay away from things that may trigger symptoms. These may include skipping meals, exposure to cold, stress, and a lot of exercise. [cedars-sinai.org]
