Abstract
Anti-Golgi antibodies are uncommon antibodies that exhibit specific, polarized cytoplasmic staining on the Hep-2 substrate. The objective of our study was to identify the clinical and laboratory features associated with anti-Golgi antibodies. We examined 4.5 years of data from a Turkish tertiary hospital in this retrospective cohort analysis. The indirect immunofluorescence staining patterns, antinuclear antibody (ANA) titres and clinical data of all patients were obtained from the hospital record system. A total of 146,055 ANAs were detected, of which 224 patients (0.15%) exhibited anti-Golgi antibody staining. In total, 39.4% of diagnosed patients had autoimmune diseases (AIDs). Of the AIDs, 26 (46.4%) were rheumatoid arthritis (RA). This is a very high rate and another remarkable point is that 17 (65.3%) of these patients had seronegative RA. High-titre results (1 ≥ 1/320) were more common in patients with AID. Anti-Ro52 was prevalent in 50% of extractable nuclear antigen (ENA)-positive patients, making it a remarkable finding. The majority of individuals with high-titre anti-Golgi antibodies had AID, particularly RA. The majority of these patients also tested negative for anti-cyclic citrullinated peptide (anti-CCP) and rheumatoid factor (RF). Finally, high-titre anti-Golgi antibodies may be an important serologic marker for seronegative RA in the Turkish population.

Liu F, Wang XQ, Zou JW, Li M, Pan CC, Si YQ. Association between serum antinuclear antibody and rheumatoid arthritis. Front Immunol 2024; 15:1358114. [PMID: 38711518 PMCID: PMC11070521 DOI: 10.3389/fimmu.2024.1358114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 03/29/2024] [Indexed: 05/08/2024] Open
Abstract
Background The relationship between serum antinuclear antibody (ANA) and rheumatoid arthritis (RA) remains unknown. Therefore, we aimed to evaluate whether serum ANA was associated with an increased risk of RA in a case-control study. Methods Patients with rheumatoid arthritis hospitalized at Shandong Provincial Hospital from January 2018 to December 2022 were recruited as the case group, and patients with other types of arthritis and healthy people at the same time were taken as the control group. Antinuclear antibody (ANA) was detected by indirect immunofluorescence assays. Propensity score matching was employed to construct a cohort of patients exhibiting comparable baseline characteristics. The relationship between serum ANA and the risk of rheumatoid arthritis was analyzed by logistic regression analysis. Results A total of 1,175 patients with RA and 1,662 control subjects were included in this study. After adjusting for potential confounding factors in the propensity-score matched cohort, the risk of RA gradually increased with rising of ANA titers. When ANA titers were divided into three groups (1:100, 1:320, and 1:1,000), the OR (95% CI) for ANA titers from low to high was 3.95 (3.01, 5.18), 16.63 (9.44, 29.30), and 17.34 (9.53, 31.54), respectively, compared to those when ANA was negative. The ANA patterns closely related to the occurrence of RA include nuclear homogeneous, nuclear speckled, and cytoplasmic speckled. Among them, the positive rate of nuclear homogeneous was the highest, which accounted for 42.64%. The OR (95% CI) of ANA patterns including nuclear homogeneous, nuclear speckled, and cytoplasmic speckled was 16.81 (11.46, 24.65), 3.40 (2.49, 4.63), and 3.09 (1.77, 5.40), respectively. Conclusion There was a curve relation between ANA titer and RA, and the higher the ANA titer, the higher the probability of RA. However, there was no statistical difference in probability of RA for 1:320 versus 1:1,000 ANA titers. The most important kind of ANA pattern in the blood of RA patients was nuclear homogeneous. These findings suggest that ANA may be a novel risk marker for RA.

The clinical value of indirect immunofluorescence for screening anti-rods and rings antibodies: A retrospective study of two centers in China. Front Immunol 2022; 13:1007257. [PMID: 36238277 PMCID: PMC9552219 DOI: 10.3389/fimmu.2022.1007257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Accepted: 09/08/2022] [Indexed: 11/22/2022] Open
Abstract
Objective To investigate the distribution and clinical significance of the rods and rings (RR) pattern in various diseases. Methods A total of 169,891 patients in Peking Union Medical College Hospital (PUMCH) and 29,458 patients in Inner Mongolia People’s Hospital (IMPH) from January 2018 to December 2020 were included, and the results of ANA (antinuclear antibodies) and special antibodies were analyzed retrospectively. Results The positive rates of ANA and RR patterns were 34.84%, 0.16% in PUMCH, and 44.73%, 0.23% in IMPH. Anti-RR antibodies mainly appear in adults (≥ 41 years), mostly of low or medium fluorescence titers. Isolated RR patterns were mostly presented (60.30% and 69.12%, respectively), and the RR pattern mixed with the speckled pattern was most commonly observed among patients having two or more patterns. The RR pattern existed in a variety of diseases including hepatitis C, AIDs, pulmonary diseases, nephropathy diseases, and even healthy people. The highest prevalence of the RR pattern was observed in hepatic diseases, such as hepatic dysfunction (0.79%), hepatic cirrhosis (1.05%), PBC (0.85%), and AIH (0.65%), etc. The positive rate of specific antibodies in RR pattern cases was 31.25%, and anti-Ro52 (27, 20.61%) was the most common target antibody. Conclusion The RR pattern had a low prevalence in ANAs test samples and varied in different nationalities and regions. Except for hepatitis C, it could be observed in AIDs, pulmonary diseases, nephropathy, other hepatic diseases, and even healthy people, but the positive rate was slightly higher in hepatic diseases. Its mechanism of action and clinical relevance still need clarification.

Abstract
OBJECTIVE To reveal the relationship between anti-Golgi antibody (AGA) and clinical diseases through retrospective analysis. METHODS The clinical data of 584 cases testing positive for AGA in the past 11 years were collected and retrospectively analyzed. RESULTS AGA pattern accounted for .2% of positive ANA results. In total, 35.0% of diagnosed patients had autoimmune diseases (AID), mainly rheumatoid arthritis (RA). High-titer AGA (≧1:1000) was common in AID. In nondiagnosed patients with clinical symptoms, joint pain/muscle pain was the most common. CONCLUSIONS Positive AGA with high titer was closely related to RA. Joint pain/muscle pain was the most common symptom in patients who tested AGA positive. Therefore, AGA may be a key indicator of RA in the Chinese population.
