Infectious and Non-infectious Diseases of the Digestive System. Epidemiological Interrelation

Background. Infectious and non-infectious diseases of the digestive system are common in Russia and worldwide and have major social and economic significance, yet the importance of infectious diseases in development of chronic digestive disorders is not adequately studied. The study aims to define epidemiologic charateristics of non-infectious diseases of the digestive system and to assess the influence of enteric infections on chronic digestive disorders development. Materials and methods. The authors conducted a retrospective epidemiologic analysis of incidence and prevalence of infectious and non-infectious digestive diseases in Russia in the period between 2002 and 2017 and in-depth for 2010–2017. Statistical analysis was done using least square method, Pearson correlation and regression analysis and statistical processing was performed using the Microsoft Excel and IBM SPSS Statistics software. Findings. During the incidence growth period for non-infectious diseases (2010–2015) in Russia a strong positive correlation is detected between incidences of infectious and non-infectious digestive diseases. In particular, Hepatithis A, Enterovirus, Rotavirus and Norovirus infections have to most significant impact on liver, biliary tract diseases, pancreas and intestinal diseases. Conclusion. Enteric infections increase the risk of development of chronic digestive diseases. Prevention of infectious diseases will allow to decrease incidence of chronic digestive diseases
