A framework for systematic clinical studies has been created by the development of a quantitative disease activity tool (the IgG4-RD Responder Index) and the validation of classification criteria, both of which were the products of international, multi-centre investigations. In addition, substantial strides have been made in understanding the pathophysiology of IgG4-RD. In particular, the central role of B cells in the disease has been demonstrated by both the robust clinical responsiveness of IgG4-RD to B cell depletion and by the identification of multiple self-antigens that promote B cell expansion. CD4+ T cells have also been investigated in detail; CD4+ cytotoxic T lymphocytes (suspected of promoting disease) and a specific T follicular helper cell subset that contributes to IgG4 isotype switching have both been defined by multiple groups. The mechanisms by which these immune cells converge on target tissues, interact with fibroblasts and promote tissue remodelling are beginning to be understood and will be an important research focus in the coming years. The determination of farmers' knowledge and attitudes towards pesticide use is very important in terms of preventing pesticide use-related short- and long-term damages. This study was aimed at investigating the relationship between the sociodemographic characteristics of farmers in Karacabey District of Bursa, a province in northwest Turkey, and their knowledge and attitudes towards pesticide use. This cross-sectional study was conducted in Karacabey district between December 2018 and April 2019. The sample size was calculated as 1924 using the Epi info program by assuming the prevalence as 50%, type I error as 5%, standard deviation as 3% and design effect as 2.
