Allopurinol is a medication commonly prescribed for managing conditions related to excess uric acid in the body, such as gout and kidney stones. While it is effective for many, certain individuals may experience severe adverse reactions due to hypersensitivity. This hypersensitivity is strongly linked to the presence of the HLA-B*5801 allele. Recognizing the symptoms of this hypersensitivity is crucial for both patients and healthcare providers to prevent potentially life-threatening reactions. DNA Labs UAE offers a specialized test to determine the presence of the HLA-B*5801 allele, helping to guide safer treatment plans for those at risk.
Understanding HLA-B*5801 Hypersensitivity
HLA-B*5801 hypersensitivity to allopurinol is a genetically predisposed condition. Individuals carrying the HLA-B*5801 allele are at a significantly increased risk of developing severe cutaneous adverse reactions (SCARs) when taking allopurinol. These reactions include Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), which can be fatal if not promptly recognized and managed.
Symptoms of HLA-B*5801 Hypersensitivity
The symptoms of HLA-B*5801 hypersensitivity to allopurinol can vary in severity and onset but typically include:
- Skin rash or hives, which may progress to severe blistering and peeling of the skin
- Fever and flu-like symptoms
- Swelling of the face, lips, tongue, or throat, which can lead to difficulty breathing
- Jaundice (yellowing of the skin or eyes)
- Unusual tiredness or weakness
- Dark urine or changes in the amount of urine
- Severe gastrointestinal symptoms, including nausea, vomiting, and abdominal pain
- Enlarged lymph nodes
It’s important for individuals taking allopurinol to be aware of these symptoms and to seek immediate medical attention if they develop.
HLA-B*5801 Test at DNA Labs UAE
DNA Labs UAE offers the HLA-B*5801 test to identify individuals at risk of hypersensitivity to allopurinol. The test is recommended for anyone starting or currently taking allopurinol, especially those with a family history of severe drug reactions or those of Han Chinese, Korean, or Thai descent, as the prevalence of the HLA-B*5801 allele is significantly higher in these populations.
The cost of the HLA-B*5801 test is 1400 AED. This investment can be invaluable in preventing the severe and potentially life-threatening reactions associated with allopurinol hypersensitivity.
