E74.10
Disorder of fructose metabolism, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
A disorder of fructose metabolism is a rare genetic condition that affects how the body processes fructose, a simple sugar found in fruits, honey, and certain vegetables. When this metabolic pathway is disrupted, it can lead to a buildup of fructose in the body, causing various health issues. The specific diagnosis, classified under ICD-10 code E74.10, refers to an unspecified disorder of this metabolic process. Recognizing the symptoms and understanding the causes can help in managing the condition and preventing complications.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting enzymes involved in fructose metabolism, primarily aldolase B deficiency Inheritance in an autosomal recessive pattern, requiring both parents to pass on the defective gene Lack of specific enzymes needed to process fructose properly Potential environmental factors that influence enzyme activity, though genetic factors are primary
Key Symptoms: Vomiting, especially after consuming foods high in fructose Severe hypoglycemia (low blood sugar levels) Jaundice (yellowing of the skin and eyes) Swelling or pain in the abdomen Lethargy or fatigue Poor feeding in infants Dehydration Failure to thrive, especially in young children
Diagnostic & Treatment
Diagnosis Path: Diagnosing a disorder of fructose metabolism typically involves a combination of clinical evaluation and laboratory testing. Key diagnostic methods include: - Blood tests to measure glucose, liver function, and uric acid levels - Fructose tolerance or tolerance tests to assess how the body handles fructose - Genetic testing to identify mutations in the ALDOB gene, which encodes aldolase B - Urinalysis to detect abnormal sugar excretion Early diagnosis is crucial for effective management, which often involves dietary modifications to avoid fructose-containing foods.
Treatment Protocols: Management of a disorder of fructose metabolism mainly focuses on reducing or eliminating intake of fructose and related sugars. Typical approaches include: - A diet restricted in foods containing free fructose, sucrose (which breaks down into glucose and fructose), and sorbitol - Regular monitoring of blood sugar levels and liver function - Education on reading food labels to avoid hidden sources of fructose - Nutritional counseling to ensure proper growth and development, especially in children - In some cases, supplementation or medication might be recommended under medical supervision to address specific metabolic issues While there is no cure for the genetic mutation itself, dietary management can significantly reduce symptoms and prevent long-term complications.
