Effects of intradialytic exercise on systemic cytokine in patients with chronic kidney disease

Abstract

Background: Immunological dysfunctions and a pro-inflammatory environment are associated with higher risk of cardiovascular diseases in chronic kidney disease (CKD). Physical exercise can be an important anti-inflammatory strategy, but the effects in CKD remain poorly investigated. Objective: Evaluate the acute inflammatory response to intradialytic exercise in the peripheral blood of individuals with CKD. Methods: Nine patients, of both genders, with CKD and allocated in the ambulatory of hemodialysis of Hospital Ernesto Dornelles (Brazil), performed two sessions of hemodialysis (HD) in random form: aerobic intradialytic exercise sessions (EX, 20 min of moderate exercise in cycle-ergometer) and a control hemodialysis session (CON). Peripheral blood collection was made at the baseline, during and immediately after HD to evaluate the cytokine profile: interleukin-6, interleukin-10 (IL-10), interleukin-17a (IL-17a), interferon-gamma (INF-g) and tumoral necrosis factor-alpha (TNF-a). Results: INF-g decreased during HD when compared with the pre moment in both sessions, while an increase in post HD was only found in the CON session. IL-17 was higher in post when compared with during HD in both sessions. In addition to the time effect, IL-10 presented a time  group interaction and the relative changes were significantly higher in EX when compared with the CON session. The relative changes in TNF-a tended to be higher in CON when compared with EX immediately post HD session. Conclusions: These data indicate that 20 min of intradialytic exercise have modest effect in systemic inflammation. However, the significant increase in IL-10 may indicate an immunoregulatory effect of physical exercise.

The Impact of Exercising During Haemodialysis on Blood Pressure, Markers of Cardiac Injury and Systemic Inflammation - Preliminary Results of a Pilot Study

“…A recent systematic review highlighted a lack of understanding of the acute effects of exercise on inflammatory markers in chronic inflammatory diseases [47]. One recent paper reported an increase in IL-10 after HD including 20 min cycling with a similar absence of changes in IL-6 and TNF-α [48]. Another study found no immediate change in CRP after intradialytic resistance exercise despite a decrease in the antioxidant superoxide dismutase [49].…”

“…The results of the study by Peres et al indicated that physical activity moderates the plasma levels of inflammatory factors (31). It should be mentioned that our study period was short.…”

The impact of intradialytic exercise on immune cells expressing CCR5+ in patients with chronic kidney disease: A cross-over trial

“…Previously published data reported the peripheral frequency of Natural Killer cells and cytokine levels in response to intradialytic exercise. 7,9 The non-inclusion criteria included patients with severe heart disease, uncontrolled arterial hypertension, thrombosis, ischemic cardiopathy, amputation, excessive pallor, severe dyspnea, femoral fistula, precordial pain, orthopedic or neurological compromising, and cognitive impairment. Additionally, eight healthy elderly (age between 60 and 80 years) individuals with no apparent diseases (i.e.…”
