| Abstrakt: | Background: Patients with symptoms (Sx) of gastroparesis (Gp) may have signs of autoimmune disease. Goals: We hypothesized that serum autoantibodies in Gp Sx patients are associated with follow-up at 48 weeks (about 11 mo) and later autoimmune questionnaires (AQ). One hundred eleven patients: 24 male, 87 female, mean age 43 years, with Gp Sx: 27 diabetic (DM), 78 idiopathic (ID), 6 postsurgical (PS) were studied at baseline, 48 weeks (about 11 mo) and long term. Serum western blot (WB) was performed by an enzyme linked immunosorbent assay for qualitative evaluation of serum antibodies to various specific nuclear antigens. A blotting score (GIBS) was used to compare global immunologic reactions. At long-term follow-up (>5 y), 38 AQ-responding patients (34 with baseline WB data) were compared with WB by AQ responses. Results: A total of 69/111 (62%) had gastric emptying delay. Correlations exist between WB autoantibodies and clinical follow-up at 48 weeks (about 11 mo). 94/96 (97.9%) were WB positive and 62/96 patients had 48-week data. From 5 years follow-up of 38 patients, AQ Sx responses were recurring abdominal pain (89%), lack of energy (87%), exhaustion (74%), and constipation (68%). From AQ and WB data (34 patients), Anti-SSA was higher in those indicating dry mouth and mouth and nose sores and SM was higher in dysphagia (P=0.01 for both). Conclusions In patients with gastroparesis symptoms baseline western blot has significant associations with a number of clinical findings and autoimmune disorders symptoms. These associations suggest possible undiagnosed autoimmune disorders. Further work with Western blotting and other autoimmune measures in patients with gastroparesis symptoms is needed.
