Background/Aims: Autoimmune gastritis patients may have autonomic nerve dysfunction. The goal of our study was to explore thepredictive value of two scoring systems in the differentiation of altered autonomic nerve function in autoimmune gastritis patients. Materials and Methods: Seventy-five patients with autoimmune gastritis were evaluated by using cardiovascular reflex tests in orderto delineate autonomic nerve function. Data were analyzed by using two laboratory-based scoring systems: “global score” (hemoglobin, mean corpuscular volume, gastrin, vitamin B12, and chromogranin A) and “simple score” (hemoglobin, mean corpuscular volume, gastrin)in order to discriminate deranged and normal autonomic nerve function.Results: Mean “simple” and “global” scores were significantly higher in subjects with altered autonomic dysfunction than in subjects with normal autonomic function (3.55±1.88 vs. 0.908±0.409, p<0.001 and 5.95±2.07 vs 2.46±1.28, p<0.001, respectively). Receiver operator characteristic (ROC) analysis revealed that the optimum “simple score” cutoff point was 0.75 with a sensitivity of 86.7% and specificity of 92.3% for discriminating autoimmune gastritis patients with autonomic nerve dysfunction from patients with normal autonomic nerve function [area under the curve (AUC): 88.3, positive predictive value (PPV): 97.5% and negative predictive value (NPV): 66.6%; 95% confidence interval (CI), 88.4-99.7].Conclusion: Simple score and global score have a high predictive value in the assessment of autoimmune gastritis patients with auto-nomic nerve dysfunction. These scoring systems may help physicians while evaluating autoimmune gastritis patients for the existence of autonomic nerve dysfunction instead of complex cardiovascular reflex tests.
