Anti-golgi antibodies: Prevalence and disease association in Chinese population

Abstract

ObjectiveAnti-golgi antibodies (AGAs) are rarely encountered and often considered in relation to autoimmune diseases in clinical practice. This research was performed for studying the prevalence and clinical significance of AGAs in Chinese population. MethodsWe retrospectively reviewed 22,619 laboratory reports of AGAs detected by indirect immunofluorescence (IIF) were consecutively collected from the First People's Hospital of Wenling between June 2012 and June 2017. Eight patients with AGAs were followed up for relevant clinical and laboratory characteristics. ResultA total of 22,619 laboratory reports were collected. Of 19 patients with AGAs, 7 cases (all females) had autoimmune diseases (AID) and 12 cases (6 females and 6 males) had non-AID. High titer AGAs ranging from 1:1000 to 1:3200 were persistently present in AID patients, while low-titer AGAs ranging from 1:100 to 1:320 were transient in non-AID patients. ConclusionThis is the first study to assess the AGA positive rate and relevant clinical manifestations in a hospitalized Chinese population. AGAs were rare and occurred in a variety of diseases. They were persistently strongly positive in AID, whereas low-titered and transient in non-AID.
