Advanced age influences the dynamic changes in circulating C-reactive protein following injury.

Background: The concentration of C-reactive protein (CRP), a biomarker of systemic inflammation, is determined by genetic, clinical and demographic factors including gender, smoking and body mass index (BMI). The influence of age on CRP dynamic changes following insult has, however, been poorly characterised.

Methods: We used unilateral hernia repair as a model of standardised insult to investigate the influence of baseline demographic and clinico-pathological factors affecting the dynamic changes in CRP, interleukin (IL) 6 and tumour necrosis factor-α over a time course of 48 h following injury.

Abdominal adiposity is the main determinant of the C-reactive response to injury in subjects undergoing inguinal hernia repair.

Background: Obesity and serum C-reactive protein (CRP) (a sensitive marker of inflammatory activity) are associated with most chronic diseases. Abdominal adiposity along with age is the strongest determinant of baseline CRP levels in healthy subjects. The mechanism of the association of serum CRP with disease is uncertain.
