Helicobacter pylori infection is reported to be associated with some extragastrointestinal manifestations, such as hematological diseases (thrombocytopenia, anemia), obesity, and fatty liver disease. The length or the volume ratio of liver to spleen was suggested to be changed in some hematological and hepatobiliary disorders. We hypothesized that the liver-to-spleen ratio may be affected in H. pylori-positive patients. In this respect, we aimed to evaluate the effect of H. pylori infection on the liver-to-spleen ratio and platelet indices.


A total of 174 patients with functional dyspepsia were included in the study. Patients were divided into group 1 (H. pylori-positive gastritis) (n=95) and group 2 (H. pylori negative, control group) (n=79). Liver, spleen length measurement, and liver steatosis scores were performed by ultrasonography by the same physicians who were blinded to the H. pylori results. Blood count values including the platelet count and the mean platelet volume (MPV) were compared between the two groups. BMI was also evaluated as a potential confounding factor for fatty liver.


The liver-to-spleen ratio, platelet-to-spleen ratio, MPV-to-spleen ratio, and the MPV-to-liver ratio were significantly lower in the H. pylori-positive group compared with the H. pylori-negative group (P<0.001, <0.001, <0.001, and 0.038, respectively). Fatty liver was significantly more frequent in H. pylori-positive patients.


Liver-to-spleen ratio and the MPV-to-spleen ratio are important indices in the pathogenesis of H. pylori-linked liver and spleen manifestations, and thrombocytopenia.
