BACKGROUND: The cholinergic anti-inflammatory pathway (CAP) modulates
inflammatory responses through the vagus nerve and the ?-7-nicotinic
acetylcholine receptor (?7nAChR) on macrophages and immune cells.
Sympathetic/parasympathetic imbalance and chronic inflammation are both linked to
poor outcome in dialysis patients. The aim of this study was to investigate CAP
activity in these patients. METHODS: Twenty dialysis patients, 12 hemodialysis
(HD) and 8 peritoneal dialysis (PD) patients (12 male, 8 female; age range 47-83
years) and 8 controls (5 male, 3 female; age range 31-52 years) were analyzed for
C-reactive protein (CRP), tumor necrosis factor (TNF), interleukin-1b (IL-1b),
IL-6 and IL-10 at baseline. The cytokines were then assessed after whole blood
stimulation ex vivo with lipopolysaccharide (LPS) (10 and 100 ng/mL) and again in
the presence of 45 and 90 ?mol/L GTS-21, a cholinergic ?7nAChR agonist. RESULTS:
CRP, TNF, IL-1 and IL-6 were significantly higher, whereas IL-10 was
significantly lower at baseline in patients compared with controls. After LPS
stimulation, TNF increased significantly more in patients than in controls but
decreased to similar levels in both groups after addition of GTS-21. IL-6
attenuation was comparable with TNF and the IL-1b pattern was similar but
remained significantly higher in patients. Interestingly, IL-10 increased after
GTS-21 in a dose-dependent manner, but only in patients. Results in HD and PD
patients did not differ. CONCLUSIONS: The response of immune cells after LPS
exposure and cholinergic stimulation suggests a functional CAP in dialysis
patients. It may thus be possible to target the ?7nAChR control of cytokine
release as an anti-inflammatory strategy and thereby improve outcome in these
patients.
