Background

Pulmonary tuberculosis remains the single deadliest infectious disease causing high mortality in humans leading to 1.4 million deaths annually. Inherited genetic factors may explain why some people resist infection more successfully than others.

Methods

The polymorphisms of HLA-class I (-A, -B) and class II (-DRB1, -DQB1) genes have been evaluated using DNA-based typing in a population of 86 non-immunosuppressed, unrelated Greek patients with PTb and 46 healthy unrelated people without a history of PTb, who were all tested purified protein derivative positive (>14 mm).

Results

The HLA-A R(114) and HLA-DRβN(37) residues are associated with susceptibility. They operate independently from each other and their effect is detected when the population is evaluated for their concurrent presence (A R(114) positive or DRβN(37) positive or A R(114) and DRβN(37) positive). Furthermore the HLA-A S(77) appears to have a protective role, however in the presence of the DRβN(37), the A-S(77) does not exert its protective effect.

Conclusion

The HLA residues A-S(77), A-R(114) and DRβN(37) in combination with PTb antigenic elements possibly modulate T-cell responses against MTb that lead to either protection or susceptibility. The HLA-A and -DRB1-dependent T-cell networks may interact among themselves and influence each other resulting in different PTb phenotypes."xsd:string
