Pacientes e métodos: Foram avaliados 97 pacientes piauienses com AR. A genotipagem do HLA-DR foi realizada através da técnica de amplificação pela reação em cadeia da polimerase. Resultados: Oitenta e cinco pacientes (88,0%) eram do sexo feminino, 77,0% não caucasoides e tinham idade média de 47,3 anos. Cinquenta e quatro pacientes (56,0%) apresentavam manifestações extra-articulares, sendo nódulos subcutâneos a mais frequente (19,0%). Após a realização de avaliação pulmonar, constatou-se comprometimento pulmonar em 54 (56,0%) pacientes. HLA mais frequente foi o HLA DRB4*01, seguido por DRB1*04, DRB3 e DRB1*01 e nos pacientes com comprometimento pulmonar foram HLA-DRB4*01, HLA-DRB1*04 e HLA-DRB1*13. Conclusão: O HLA mais frequente foi o HLA-DRB4*01 em todos os pacientes do estudos e nos pacientes com envolvimento pulmonar também foi o HLA-DRB4*01, não havendo, no entanto, associação estatisticamente significativa / Abstract: Aims: To establish the frequency of HLA-DR antigens in individuals with rheumatoid arthritis (RA) from Piaui with and without lung affection. Participants and methods: The sample comprised 97 individuals. HLA-DR was genotyped by means of polymerase chain reaction amplification. Results: A total of 85 participants (88.0%) were female; 77.0% were non-white; and the average age of the sample was 47.3 years old. A total of 54 participants (56.0%) exhibited extra-articular manifestations, most frequently subcutaneous nodules (19.0%). Lung assessment detected affection in 54 (56.0%) participants. HLA-DRB4*01 was the most frequently found allele, followed by HLA-DRB1*04, HLA-DRB3 and HLA-DRB1*01, whereas the most frequent alleles were HLA-DRB4*01, HLA-DRB1*04 and HLA-DRB1*01 in the participants with lung affection. Conclusion: HLA-DRB4*01 was the allele most frequently found overall, and HLA-DRB4*01 was the most frequent allele among the participants with lung affection; however, the association was not statistically significant / Doutorado / Medicina Interna / Doutora em Ciências Médicas
