Insights
Chronic kidney disease (CKD) significantly increases cardiovascular disease (CVD) risk and mortality. Targeting the NLRP3-IL-1β-IL-6 pathway offers a promising anti-inflammatory therapy for CKD patients with persistent inflammation.
Area of Science:
- Nephrology
- Cardiology
- Immunology
Background:
- Chronic kidney disease (CKD) is a major independent risk factor for cardiovascular diseases (CVD), leading to increased cardiovascular mortality.
- Inflammation, driven by endothelial cell and innate immune system interactions, is a key link between CKD and CVD.
- CKD-induced uremic toxins cause vascular injury, endothelial dysfunction, and immune system activation, exacerbating CVD risk.
Purpose of the Study:
- To explore the role of inflammation in the CKD-CVD link.
- To investigate CKD-associated changes in monocytes and their impact on endothelial dysfunction.
- To highlight the significance of the NLRP3-IL-1β-IL-6 pathway in CKD and CVD pathogenesis.
Main Methods:
- Review of recent studies on CKD, CVD, inflammation, and immune system interactions.
- Analysis of the role of uremic toxins in vascular injury and endothelial dysfunction.
- Examination of the NLRP3-IL-1β-IL-6 signaling pathway in CKD and CVD.
Main Results:
- CKD promotes vascular inflammation and endothelial dysfunction through metabolic changes and uremic toxins.
- Monocyte alterations in CKD contribute to endothelial dysfunction, worsening CKD and associated CVD.
- The NLRP3-IL-1β-IL-6 pathway is critically involved in the progression of both CKD and CVD.
Conclusions:
- Targeted anti-inflammatory therapies, particularly inhibiting the NLRP3-IL-1β-IL-6 pathway, show potential for managing CKD-associated CVD.
- CKD patients with nonresolving inflammation could significantly benefit from novel anti-inflammatory strategies.
- Current therapeutic regimens have limited efficacy for CKD patients, underscoring the need for new approaches.
Abstract:
Chronic kidney disease (CKD) represents an independent risk factor for cardiovascular diseases (CVD). Accordingly, CKD patients show a substantial increased risk of cardiovascular mortality. Inflammation represents an important link between CKD and CVD. The interaction between endothelial cells and effector cells of the innate immune system plays a central role in the development and progression of inflammation. Vascular injury causes endothelial dysfunction, leading to augmented oxidative stress, increased expression of leukocyte adhesion molecules and chronic inflammation. CKD induces numerous metabolic changes, creating a uremic milieu resulting in the accumulation of various uremic toxins. These toxins lead to vascular injury, endothelial dysfunction and activation of the innate immune system. Recent studies describe CKD-dependent changes in monocytes that promote endothelial dysfunction and thus CKD progression and CKD-associated CVD. The NLR family pyrin domain containing 3-interleukin-1β-interleukin-6 (NLRP3-IL-1β-IL-6) signaling pathway plays a pivotal role in the development and progression of CVD and CKD alike. Several clinical trials are investigating targeted inhibition of this pathway indicating that anti-inflammatory therapeutic strategies may emerge as novel approaches in patients at high cardiovascular risk and nonresolving inflammation. CKD patients in particular would benefit from targeted anti-inflammatory therapy, since conventional therapeutic regimens have limited efficacy in this population.
