RESUMEN
Carnitine is an essential cofactor for fatty acid metabolism. Deficiencies can be associated with muscle weakness, fatigue, weight loss, and cardiomyopathies. A 27-year-old woman with short bowel syndrome (SBS) presented with significant weight loss, fatigue, and muscle wasting despite adequate parenteral nutrition. Her laboratory test results revealed carnitine deficiency secondary to malnutrition. Levocarnitine supplementation was initiated with normalization of her carnitine levels. Her fatigue improved, and her weight returned to baseline. Carnitine deficiencies are seldomly reported in adults, particularly those with SBS. Carnitine deficiency should be suspected and corrected in patients with SBS and malabsorptive capacity due to surgical resection.
RESUMEN
New antibiotic options are urgently needed for the treatment of carbapenem-resistant Enterobacteriaceae infections. We report a 64-year-old female with prolonged hospitalization following an intestinal transplant who developed refractory bacteremia due to a serine carbapenemase-producing pandrug-resistant isolate of Klebsiella pneumoniae. After failing multiple antimicrobial regimens, the patient was successfully treated.
