Acetylation phenotype distribution (activity of N-acetyltransferase enzyme) was studied in 29 patients with periodical disease (PD), 73 healthy persons (Armenians), and 20 patients (also Armenians) suffering from epithelial coccygeal cysts. The results obtained indicated the prevalence of slow acetylation phenotype (67%) in the entire Armenian population. ⋯ The other hereditary pathology, also specific for Armenians (epithelial coccygeal cysts), was characterized by another type of acetylation--a rapid one. The role of slow acetylation as a genetic marker of PD was discussed.

HLA-antigens were studied in 116 Greek patients: 22 with pSS, 14 with sSS and RA, 26 with classical RA and 420 healthy controls. A statistically significant increase in HLA-DR5 was observed mainly in pSS patients with anti-Ro (SSA). A significant increase in HLA-B8, HLA-DR3 and HLA-DR5 was observed in pSS patients with anti-La (SSB) antibodies as compared to the controls.
