A clinical and epidemiological study of human leukocyte antigen-DPB alleles in Hodgkin's disease
1ICRF Department of Medical Oncology, St. Bartholomew's Hospital, London, United Kingdom.
Insights
Human Leukocyte Antigen (HLA)-DPB alleles are linked to Hodgkin's disease risk and prognosis. Specific alleles, like HLA-DPB1*0301, show increased frequency in white patients, while others impact remission duration.
Area of Science:
- Immunogenetics
- Oncology
- Epidemiology
Background:
- Hodgkin's disease (HD) is a heterogeneous lymphoid malignancy.
- The role of specific human leukocyte antigen (HLA) alleles in HD susceptibility and progression requires further investigation.
Purpose of the Study:
- To investigate the association between HLA-DPB alleles and the risk of developing Hodgkin's disease.
- To explore the prognostic significance of HLA-DPB alleles in Hodgkin's disease patients.
Main Methods:
- International collaborative study involving 17 centers across 12 countries.
- Typing of 741 HD patients and 686 controls for HLA-DPB alleles using PCR and sequence-specific oligonucleotide hybridization.
- Clinical data analysis of 551 patients to assess remission duration in relation to HLA-DPB alleles.
Main Results:
- A significantly increased frequency of HLA-DPB1*0301 was observed in white patients with HD (relative risk = 1.95, P < 0.01).
- A significant reduction in HLA-DPB1*0401 frequency was noted in Japanese and Taiwanese patients (relative risk = 0.15, P < 0.01).
- The HLA-DPB1*0901 allele was associated with significantly inferior remission duration in HD patients overall and particularly in Japanese and Taiwanese populations.
Conclusions:
- HLA-DPB alleles demonstrate both epidemiological and potential prognostic associations with Hodgkin's disease.
- Specific HLA-DPB alleles may influence susceptibility and clinical outcomes in Hodgkin's disease.
- Further research into HLA-DPB genetics could inform diagnostic and therapeutic strategies for Hodgkin's disease.
Abstract:
An international study to investigate the role of human leukocyte antigen (HLA)-DPB alleles in Hodgkin's disease was conducted with 17 participating centers in 12 countries. A total of 741 patients and 686 controls were typed using polymerase chain reaction amplification of HLA-DPB alleles and subsequent sequence specific oligonucleotide hybridization. The frequency of HLA-DPB1*0301 was found to be significantly increased in white patients, compared with ethnically matched controls. In this population group, the DPB1*0301 allele is associated with a relative risk of 1.95 (P < 0.01). There was also a significant reduction in the frequency of HLA-DPB1*0401 in patients from Japan and Taiwan (relative risk, 0.15; P < 0.01). Clinical analysis from data on 551 patients demonstrated a significantly inferior remission duration in patients with HLA-DPB1*0901, overall (P < 0.05), and in the Japanese and Taiwanese populations (P = 0.02), where this allele is most prevalent. This analysis suggests an epidemiological as well as a possible prognostic association between HLA-DPB alleles and Hodgkin's disease.
