The value of anti-rods and rings antibodies in Chinese population of Dalian City: A retrospective study.

The study aimed to investigate the clinical significance of anti-rods and rings (anti-RR) antibodies in antinuclear antibodies (ANAs) test samples retrospectively. The laboratory data and clinical details of patients with positive anti-RR antibodies were collected and analysed between December 2017 and May 2022 in the First Affiliated Hospital of Dalian Medical University. A total of 72 665 patients were tested for ANAs. There were 45 632 patients discovered with positive ANAs (62.80%), only 131 patients presented with anti-RR antibodies (0.18%), among which only 68 patients were hospitalized patients with a definitive diagnosis. Among the 68 patients with a definitive diagnosis, 8 of 68 (11.8%) had autoimmune diseases, and 19 of 68 (27.9%) had renal diseases. Other diseases included liver disease, pulmonary disease, cerebral ischemia, cerebral infarction, chronic cardiac failure and venous thromboembolism. The detection rate of high titre(≥1:1000) anti-RR antibodies is significantly higher in autoimmune diseases.

The value of anti-rods and rings antibodies in Western China population: A retrospective study.

The study aimed to retrospectively investigate the clinical significance of anti-rods and rings (anti-RR) antibodies in antinuclear antibodies (ANAs) test samples of western China. Between January 2016 and November 2018, the laboratory data and clinical details of patients with positive anti-RR antibodies were collected and analysed. The results showed that total of 197 227 patients tested, 109 453 patients presented with positive ANAs (55.50%), but only 107 patients with positive anti-RR antibodies (0.10%), including 51 females and 56 males. Diagnose were established in 51 of 107 patients: 25 were hepatopathy (HCV 8/25, HBV 12/25); 13 were autoimmune diseases (AID); and 7 were renal insufficiency; 6 were chronic obstructive pulmonary disease (COPD). We make the conclusions that anti-RR antibodies have a low prevalence, and there is no gender difference. Anti-RR antibodies exist other diseases besides hepatitis C, such as HBV, some autoimmune diseases, renal insufficiency and COPD, which we need further investigation.
