摘  要:目的探讨中国山东人群HLA-A、HLA.B、HLA—DRB1、HLA—DQ等位基因与麻风病的相关性。方法采用序列特异性引物聚合酶链反应法(PCR—SSP)对40例麻风病患者及20例健康对照者进行HLA.A、B、DRB1、DQ等位基因分型,,检验基因频率差异。结果麻风病患者HLA—B$13(,=7.067,P=0.008)、DQ女02(,=4.156,P=0.041)基因频率较健康对照组低,有统计学意义(P〈0.05)。LL型麻风患者HIJA—B%13(,=7.159,P=0.007)等位基因频率降低、HLA—DRB1*15(X2=4.073,P=0.044)等位基因频率升高,与健康对照组相比均具有统计学意义(P〈0.05)。TT型麻风病患者HLA.B%40(P=0.037)、DQ%05(,=5.147,P=0.023)等位基因频率高于健康对照组,差异具有统计学意义(P〈0.05)。结论HLA.B。13、DQ*02基因可能对麻风病易感性有拮抗作用,可能是保护基因;HLA.B%13可能是LL型拮抗基因、DRB1%15可能是LL型的易感基因;HLA-B*40、DQ*05可能是TT型的易感基因。Objective To explore the association of HLA-A, HLA-B, HLA-DRB1, HLA-DQ alleles with leprosy in population of Jinan. Methods PCR-SSP was used to analyse the type of HLA-A, HLA-B, HLA- DRB1 and HLA-DQ alleles in 40 patients with leprosy and 20 healthy controls. SPSS 11.5 software package was used to analyze the data. Results The allele frequencies of HLA-B * 13 (χ2 =7.067 ,P =0. 008) and DQ * 02(χ2 =4. 156,P =0.041 ) were lower in leprosy patients than those in healthy eontrols(P 〈0.05). The allele frequencies of HLA-B * 13 (χ2 =7. 159 ,P =0. 007 )was lower than that in controls and the frequencies of HLA-DRB1 * 15 (χ2 = 4. 073, P = 0.044 ) was higher in LL leprosy patients ( P 〈 0.05 ). The allele frequencies of HLA-B * 40 ( P = 0. 037 ) and DQ * 05 (χ2 = 5. 147, P = 0. 023 ) were higher in Tr leprosy patients ( P 〈 0.05 ). Conclusion HLA-B * 13 and DQ * 02 possibly play protective rolos in leprosy patients. B * 13 has .also protective roles and DRB1 * 15 was a susceptibility gene in LL leprosy patients. B * 40,DQ * 05 may be susceptibility genes in TT leprosy patients.
