allopurinol genetic testing
Universal testing for the HLAB5801 allele prior to starting allopurinol is conditionally recommended against in individuals of other ethnic or racial background over testing for the HLAB5801 allele. Genotype testing to determine the presence of the HLA-B5801 allele in individuals from a population who are at high risk due to ethnic heritage for whom the use of allopurinol is being considered for treatment is considered medically necessary.

Moderate evidence supports allele testing for HLA-B5801 before initiating allopurinol to decrease the incidence of SCARs in higher risk populations.
. Identifying individuals with an increased risk of severe cutaneous adverse reactions to allopurinol based on the presence of the human leukocyte antigen HLA-B5801 allele Special Instructions Informed Consent for Genetic Testing Pharmacogenomic Associations Tables Multiple Genotype Test List Informed Consent for Genetic Testing Spanish. In 55 1527 of patients with allopurinol-induced scar whereas only 15 181822 of the controls tested positive for the allele table 136one recent meta-analysis that consolidated all the published studies gave the odds ratios for allopurinol- induced scar in hla-b5801carriers as 73 and 165 for stud- ies using healthy controls and. Specific information regarding therapeutic management is provided for some pharmacogenetic associations listed in the table but most of the associations listed have not been evaluated in terms of.
HLA-B5801 Typing - HLA B5801 has been associated with severe cutaneous adverse reactions SCAR in response to the drug Allopurinol. What is pharmacogenomic testing. This means that among 100 allopurinol users with positive HLA-B5801 two patients may develop SCAR while among 100 patients tested negative almost all patients are unlikely to develop SCAR provided there are no other non-genetic factors involved.
Genetic testing to avoid allopurinol hypersensitivity More HLA testing can identify individuals at high genetic risk of developing a severe cutaneous adverse reaction to allopurinol. Healthcare professionals are advised to use allopurinol with caution. Pre-emptive screening for the HLA-B5801 allele has been shown to reduce the incidence of SCAR in new users of allopurinol in Europe Asia and the US 2.
Patient populations who are not at. Ad See how Elitek works. Allopurinol has a long-established role in the management of hyperuricaemia and gout.
Clinicians and policy makers may use our findings as a foundation to support the implementation of genetic testing prior to initiation of allopurinol. The human leukocyte antigen B HLA-B plays an important role in how the immune system recognizes and responds to pathogens. Conditional recommendations are those which would warrant provider-individual shared medical decision-making discussion.
We quantified allopurinol use data and the magnitude of adverse event signals using us fda databases reviewed reported cases of allopurinol-associated severe cutaneous adverse reactions to. Allopurinol is a medication that is most commonly used for treating hyperuricemia elevated uric acid level in the blood and gout. The allopurinol hypersensitivity assay or HLA-B5801 test is a blood test to detect the presence of a human leukocyte antigen B HLA-B genetic variant that increases the risk of.
Allopurinol associated SCAR severe cutaneous adverse drug reaction including Stevens-Johnson syndrome SJS and toxic epidermal necrolysis TEN has been shown to be associated with the human leukocyte antigen HLA B5801 of the major histocompatibility complex MHC. This podcast by the co-chair of the panel clarifies the details. Everything you need to know about Elitek.
The MHC family of genes codes for a highly variable set of cell. Studies in the United States have suggested that Asians and Blacks have substantially increased risk of allopurinol-associated SJSTEN as compared to Whites and Hispanics which correlates with the allele frequency 74 4 1 and 1 respectively. GTR Test ID Help Each Test is a specific orderable test from a particular laboratory and is assigned a unique GTR accession number.
The PPV is low at 2 and the Negative Predictive Value NPV of the genotyping test is nearly 100. It is most commonly used in the management of gout and hyperuricemia high levels of uric acid. Who and How October 10 2012 RheumatologyNetwork Staff AUDIO New ACR guidelines on gout advise considering a test for the HLA-B5801 allele linked to allopurinol sensitivity in some patients.
However screening for the HLA-B5801 allele is not as widespread in the US compared to Taiwan and other Asian countries 1 2. Knowing what type of HLA genes you have can help your healthcare providers select the right medication for your condition and prevent harmful effects. Genetic Testing of Gout Patients for Allopurinol Sensitivity.
We quantified allopurinol use data and the magnitude of adverse event signals using us fda databases reviewed reported cases of allopurinol-associated severe cutaneous adverse reactions to assess whether clinical subtypes of patients could be identified performed pooled analyses of associations between hla variation and allopurinol-induced. Genotyping may be considered in patients who have other pre-existing risk factors such as renal impairment to identify patients at high risk of allopurinol-induced SCAR. The Clinical Pharmacogenomic Implementation Consortium CPIC has published an article recommending genotyping prior to getting allopurinol treatment and recommended that the drug should not be administered to patients with the.
Genetic testing should not substitute for appropriate clinical vigilance and patient management. These findings reveal that the risk of developing SJSTEN among those allopurinol users with HLA-B5801 is significantly increased by 80-97 times compared to those without the gene. In contrast to carbamazepine which is ethnicpopulation specific the HLA-B5801 for detecting allopurinol-induced TENSJS is universal.
HLA-B5801 Genotype Allopurinol Hypersensitivity. NIH Genetic Testing Registry. See full safety prescribing info Boxed Warning.
Allopurinol is a xanthine oxidase inhibitor that decreases the production of uric acid. The format is GTR000000011 with a leading prefix GTR followed by 8 digits a period then 1 or more digits representing the. Screening of HLA-B5801 may help patients to prevent the occurrence of allopurinol-induced TENSJS especially in populations with a higher 5 risk allele frequency.
