Abstract
- Cilj: Istražiti učestalost haplotipskih sveza HLA-DRB1-DQA1-DQB1 te produženog haplotipa Cw*0602-B57-DRB1*07-DQA1*0201 DQB1*0201 u pacijenata s pozitivnom i negativnom obiteljskom anamnezom psorijaze. Ispitanici i metode: Istraživanje povezanosti gena sustava HLA razreda I i II sa psorijazom obuhvatilo je 118 nesrodnih pacijenata s vulgarnom psorijazom. Učestalost haplotipskih sveza ispitana je serološki i metodom hibridizacije specifičnim probama. Rezultati: Utvrđena je povišena učestalost haplotipa DRB1*07-DQA1*0201- -DQB1*0201 i DRB1*07-DQA1*0201-DQB1*0303 u psorijatičara s pozitivnom obiteljskom anamnezom te također produženog haplotipa Cw6-B57-DRB1*0701-DQA1*0201- -DQB1*0201 (P = 0,004). U psorijatičara s negativnom obiteljskom anamnezom učestalost produženog haplotipa gotovo je ista kao u kontrolnoj skupini. Zaključak: Rezultati istraživanja ukazuju na jaču i značajniju povezanost s podložnim haplotipovima HLA za pacijente s pozitivnom obiteljskom anamnezom psorijaze, stoga upućuju na značajnu ulogu gena sustava HLA u nasljeđivanju psorijaze.<br />Aim: To analyze the distribution of HLA-DRB1-DQA1-DQB1 haplotypes as well as the extended haplotype Cw*0602-B57-DRB1*07 DQA1*0201-DQB1*0201 in patients with positive and negative family history of psoriasis. Patients and methods: The association of HLA genes classes I and II with psoriasis has been studied in 118 patients with chronic stable psoriasis. The frequency of HLA haplotypes was analyzed by means of serology and hybridization with specific oligonucleotide probes. Results: The group with positive family history showed a significant association with DRB1*07-DQA1*0201-DQB1*0201 and DRB1*07- DQA1*0201-DQB1*0303 as well as with the extended haplotype Cw6-B57-DRB1*0701- DQA1*0201-DQB1*0201 (P = 0,004). The frequency of extended haplotype in the group with negative family history was similar to the control group. Conclusion: Psoriatics with positive family history show stronger association with susceptible
