Association of MICA and NKG2D genetic variants with disease susceptibility and outcome of anti-TNF therapy in patients with axial spondyloarthritis.
Objectives: The disruption of the NKG2D-MICA axis can induce an enhanced immune response and promote autoimmune processes during axial spondyloarthritis (axSpA) pathogenesis. We aimed to investigate potential relationships between selected single nucleotide polymorphisms within the MICA and NKG2D genes and disease susceptibility and clinical parameters in axSpA patients treated with TNF inhibitors.
Methods: Genotyping of MICA rs1051792 and NKG2D rs1154831, rs1049174, and rs2255336 was performed in 163 axSpA patients and 234 healthy controls using a real-time PCR method.
Results: MICA rs1051792 A allele was more common in patients than in controls (p<0.0001). Patients with the AA genotype showed greater disease activity score (BASDAI) after three (p=4×10-4) and six (p=0.032) months of treatment compared to G carriers. After three months of therapy with anti-TNFs, the MICA AA homozygosity occurred more often in non-responsive or moderately responsive patients than good responders with the same genotype (p=1×10-4). Additionally, patients bearing the NKG2D rs1154831 CC genotype demonstrated lower BASDAI scores (p=0.035) and were significantly more common among subjects with a good outcome (p=0.004) after six months of treatment.
Conclusions: These results suggest that MICA and NKG2D gene polymorphisms may be biomarkers associated with disease susceptibility and clinical outcomes after anti-TNF therapy in axSpA patients and imply a rather less favourable effect of the MICA A and NKG2D G genetic variants.
