E80.3
Defects of catalase and peroxidase
Clinical Classification Guidelines
Inclusion Terms
- Acatalasia [Takahara]
Medical Intelligence & Overview
Defects of catalase and peroxidase, classified under ICD-10 code E80.3, refer to rare conditions involving deficiencies or abnormalities in these crucial enzymes. Catalase and peroxidase play vital roles in protecting cells from oxidative damage by breaking down harmful hydrogen peroxide. When these enzymes are defective or deficient, it can lead to increased cellular stress and potential health issues. One specific condition associated with these enzyme defects is acatalasia, a rare genetic disorder characterized by the absence of catalase activity.
Causes & Symptoms
Clinical Causes: Genetic mutations leading to enzyme deficiencies Inheritance of defective genes in an autosomal recessive pattern Acatalasia often inherited as an autosomal recessive trait Potential environmental factors impacting enzyme function (less common)
Key Symptoms: Increased susceptibility to oxidative stress Possible development of oral ulcers or lesions in acatalasia Delayed wound healing Unusual oral or mucosal necrosis in some cases Rarely, symptoms related to systemic oxidative damage
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation and laboratory testing. Specific tests measure the activity of catalase and peroxidase enzymes in tissue or blood samples. Genetic testing can identify mutations associated with enzyme defects. In cases of suspected acatalasia, direct measurement of oral mucosal catalase activity is often performed to confirm the diagnosis.
Treatment Protocols: Currently, there is no definitive cure for enzyme defects like catalase and peroxidase deficiencies. Management focuses on reducing oxidative stress and preventing complications. This may include dietary modifications, antioxidant supplementation, and careful monitoring of symptoms. Supportive treatments and regular follow-up with healthcare providers are essential for maintaining quality of life.
