Clinical study of the blood tests SS‐A and SS‐B in outpatients with dry mouth syndrome

抄録

We did a retrospective study to analyze the features of dry mouth using medical interview data and the SS‐A and SS‐B in the initial blood screening examinations. The records of 330 patients with dry mouth were selected for this study. There were 51 males and 279 females between 27 and 102 years of age with a mean of 67 years. The greatest number of subjects were in the age bracket between 71 and 80 years (37.0% (122/330)), and the male/female ratio was 51 (15.5%):279 (84.5%). Total positive rate for SS‐A was 19.1% (63/330), for which the male/female ratio was 3 (4.8%):60 (95.2%). The greatest number of subjects in this group were in the age bracket between 71 and 80 years 28.6% (18/68). The total positive rate for SS‐B was 7.3% (24/330), for which the male/female ratio was 0 (0%):24 (100%). The greatest number of subjects were in the age bracket between 71 and 80 years (50.0% (12/24)). All of the subjects who were positive for SS‐B were also positive for SS‐A. Sjögren syndrome (SS‐A and SS‐B) are important initial screening factors for dry mouth syndrome in outpatients. (J Osaka Dent Univ 2019; 53: 157‐160)
