Carnitine palmitoyltransferase II (CPT2) deficiency is a rare inherited disorder affecting fatty acid metabolism. This enzymatic defect presents with a broad clinical spectrum, from severe neonatal forms that can be fatal, to milder myopathic variants characterized by myalgia and recurrent myoglobinuria in adolescence and adulthood. Herein, we report the case of a male patient who developed exertional rhabdomyolysis and acute kidney injury due to CPT2 deficiency. This case underscores the importance of considering genetic disorders in the differential diagnosis of patients presenting with recurrent exercise intolerance and metabolic crises. Early recognition and diagnosis enable prompt implementation of dietary and lifestyle modifications aimed at mitigating potential complications such as renal impairment. Moreover, timely diagnosis allows for genetic counseling of affected individuals and their families.

The most common cause of rhabdomyolysis is trauma. In the presence of rhabdomyolysis attacks triggered by heavy exercise and fever, hereditary causes should be investigated. In our study, a case was presented that developed rhabdomyolysis and acute kidney injury due to carnitine palmitoyltransferase 2 (CPT2) deficiency and then required hemodialysis treatment.

Patients with fatty acid oxidation disorders (FAODs) experience muscle symptoms due to impaired ATP metabolism and the toxicity of accumulated mitochondrial FAO substrates or intermediates, especially during catabolic states. A major issue is the absence of specific and sensible biomarkers to evaluate metabolic equilibrium. The relationship between cardiac output (Q) and oxygen consumption (VO) during incremental exercise (dQ/dVO) provides an indirect surrogate of mitochondrial function.

B cell activation is accompanied by dynamic metabolic reprogramming, supported by a multitude of nutrients that include glucose, amino acids, and fatty acids. Although several studies have indicated that fatty acid mitochondrial oxidation is critical for immune cell functions, contradictory findings have been reported. Carnitine palmitoyltransferase II (CPT2) is a critical enzyme for long-chain fatty acid oxidation in mitochondria.

Carnitine Palmitoyl Transferase Type II (CPT II) deficiency is a disorder of fatty acid beta oxidation that causes decreased adenosine triphosphate (ATP) and ketone production during periods of fasting or high energy requirements. Labor and delivery can precipitate attacks for parturients with this disorder, causing hypoglycemia, muscle weakness, rhabdomyolysis, and kidney failure. Anesthetic management considers the delivery mode and anesthetic medications available to reduce these risks.
