HLA-B*5701 Typing - Abacavir therapy for HIV treatment is associated with significant drug hypersensitivity in approximately 8% of recipients, with retrospective studies indicating a strong association with the HLA-B*5701 Allele. HLA-B*5701 typing can be used for genetic risk stratification prior to initiation of Abacavir therapy.

HLA-B*5701 is a genetic variation that is linked to hypersensitivity to the antiretroviral (ARV) drug abacavir. A person who tests positive for HLA-B*5701 should not use abacavir or any other abacavir-containing medicine.

Advise the prescriber to prescribe an alternative according to the current guidelines. Literature: 1. The HLA-B5701 Assay Mix consists of gene-specific primers and dual-labeled hydrolysis probes for HLA-B5701 and a control gene. A positive and a negative control for HLA-B5701 are supplied with the kit. 4.

A person who tests positive for HLA-B*5701 should not use abacavir or any other abacavir-containing medicine. HLA-B*5701-positive patients should not be prescribed ABC (AI). The positive status should be recorded as an ABC allergy in the patient’s medical record (AII). When HLA-B*5701 screening is not readily available, it remains reasonable to initiate ABC with appropriate clinical counseling and monitoring for any signs of HSR (CIII).

People with this specific variant in the HLA-B gene develop a severe skin reaction to the  Farmakogenetik; HLA-B57; HLA-B5701. Indikationer / kompletterande analyser: Patienter som behandlas med abakavir och är positiva för HLA-B*5701 har en  HLA-B*57:01, typning, B-. Alternativa sökord.

Hypersensitivity to abacavir is immunologically mediated, driven by conventional MHC-I antigen presentation and activation of HLA-B*5701. [ 4, 5] Activation of HLA-B*5701 restricted CD8+ T cells

The MHC family of genes codes for a highly variable set of cell surface glycoproteins (HLAs) that play a critical role in presenting antigens to T cell receptors to elicit an immune response.

HLA-B*5701 genotype is a major determinant of drug-induced liver injury due to flucloxacillin

It is known, for example, that mutations in the HLA-B*5701 gene may be partly responsible. If you are HLA-B*5701 positive, the risk of severe liver damage is increased. Determination of the presence or absence of HLA B*5701: Method: Molecular: Test Information: Molecular typing methods used to determine the presence or absence of the HLA B*5701 allele. Sample Requirements: Anticoagulated Blood ACD (yellow top, solution A or B) Requested Volume: One 7-10 ml ACD (yellow top) tube: Shipping Information Hypersensitivity to abacavir has been strongly associated with the major histocompatibility complex class I human leukocyte antigen (HLA), specifically the HLA-B*57:01 allele. Hypersensitivity to abacavir is immunologically mediated, driven by conventional MHC-I antigen presentation and activation of HLA-B*5701.
