Elderly individuals frequently experience osteoarthritis, a degenerative joint ailment. The factors contributing to the origin and advancement of osteoarthritis include non-clinical variables and genetic predispositions. Through a Thai population study, this research explored if there was a relationship between HLA class II alleles and the appearance of knee osteoarthritis.
Using the PCR-SSP technique, HLA-DRB1 and -DQB1 alleles were identified in 117 individuals with knee osteoarthritis and a control group of 84 people. The investigation explored the association of knee osteoarthritis with the presence of certain HLA class II alleles.
A notable elevation in the frequencies of DRB1*07 and DRB1*09 was detected in patients when compared to controls, while the frequencies of DRB1*14, DRB1*15, and DRB1*12 exhibited a corresponding decrease. There was a notable rise in the frequencies of DQB1*03 (DQ9) and DQB1*02 in the patient group, simultaneously with a fall in the frequency of DQB1*05. The DRB1*14 allele frequency was significantly lower (56% vs. 113%, p=0.0039) in patients compared to controls, with an odds ratio of 0.461 and a 95% confidence interval of 0.221–0.963. Conversely, the DQB1*03 (DQ9) allele was significantly more frequent in patients (141% vs. 71%, p=0.0032), exhibiting an odds ratio of 2.134 and a 95% confidence interval of 1.067–4.265. The DRB1*14-DQB1*05 haplotype's impact on knee osteoarthritis was noteworthy, showcasing a significant protective effect (p = 0.0039, OR = 0.461, 95% CI: 0.221 – 0.963). An opposite outcome was observed for HLA-DQB1*03 (DQ9) and HLA-DRB1*14, where HLA-DQB1*03 (DQ9) appeared to elevate the propensity for disease, while HLA-DRB1*14 seemed to provide a shield against knee osteoarthritis.
Knee OA demonstrated a stronger presence in women, notably those aged 60 or older, than it did in men. Conversely, a different impact was observed with respect to HLA-DQB1*03 (DQ9) and HLA-DRB1*14, where possession of HLA-DQB1*03 (DQ9) appears to increase the likelihood of developing the condition, whereas HLA-DRB1*14 appears to diminish the risk of knee osteoarthritis. EN450 cost However, subsequent analysis with a larger participant pool is crucial.
Female patients demonstrated a more prominent presence of knee osteoarthritis (OA), especially within the 60-year-old demographic, when compared to their male counterparts. In a contrasting manner, the impact of HLA-DQB1*03 (DQ9) and HLA-DRB1*14 was examined, revealing that HLA-DQB1*03 (DQ9) seems to heighten disease susceptibility, while HLA-DRB1*14 seems to be a protective characteristic against knee OA. However, the need for a more comprehensive investigation with a larger participant pool remains.
This study aimed to explore the role of morphology, immunophenotype, karyotype, and fusion gene expression in a patient diagnosed with AML1-ETO positive acute myeloid leukemia.
