Introduction: Cardiovascular, respiratory, and cerebrovascular diseases and malignancies are responsible for morbidity and mortality in acromegaly. Also these diseases are associated with chronic inflammation. The neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are currently gaining interest as new markers of inflammation. Moreover, increased morbidity and mortality are positively correlated with the presence of diabetes and levels of insulin-like growth factor 1 (IGF-1) in acromegaly. The objective of the present study was to investigate the relationship between these markers and acromegaly according to plasma glucose status and serum IGF-1 levels.
