ABSTRACT
Objective: To understand the disease progression and human leukocyte antigen (HLA) gene polymorphism of HIV-infected persons without disease progress for long term, also known as long-term non-progressors (LTNPs), in Henan province. Methods: A retrospective study was conducted in 48 LTNPs with complete detection and follow-up information during 2011-2016 in Henan. Changes of CD(4)(+)T cells counts (CD(4)) and viral load (VL) during follow-up period were discussed. Polymerase chain reaction-sequence-specific oligonucleotide probe (PCR-SSOP) was used for the analyses of HLA-A, HLA-B and HLA-DRB1 alleles between LTNPs and healthy controls. Results: From 2011 to 2016, forty-eight LTNPs showed a decrease of the quartile (P(25)-P(75)) of CD(4) from 601.00 (488.50-708.72)/μl to 494.00 (367.00-672.00)/μl, and the difference was significant (P<0.05). The increase of the quartile (P(25)-P(75)) of log(10)VL from 3.40 (2.87-3.97) to 3.48 (2.60-4.37), but the difference was not significant (P>0.05). HLA polymorphism analysis revealed that HLA-B*13:02 and HLA-B*40:06 were more common in LTNPs (P<0.05), while HLA-B*46:01 and HLA-DRB1*09:01 were more common in healthy controls (P<0.05). Conclusions: The CD(4) of LTNPs in Henan showed a downward trend year by year. HLA-B*13:02 and B*40:06 might be associated with delayed disease progression for HIV infected persons in Henan.
