Smoking--an emerging risk factor for renal diseases

Area of Science:

• Nephrology
• Public Health
• Cardiovascular Medicine

Background:

• Smoking is a major cause of preventable morbidity and mortality.
• Established links exist between smoking and cardiovascular, pulmonary diseases, and cancers.
• The detrimental effects of smoking on kidney function are often underestimated by healthcare professionals.

Purpose of the Study:

• To review existing literature and present evidence on the adverse effects of smoking on renal health.
• To highlight the association between smoking and the progression of chronic kidney disease (CKD).
• To emphasize the risk of developing end-stage renal disease (ESRD) in smokers.

Main Methods:

• Systematic review of available scientific literature.
• Analysis of studies investigating the impact of smoking on kidney function and disease progression.
• Synthesis of evidence linking smoking to various renal pathologies.

Main Results:

• Smoking accelerates the decline of kidney function in individuals with pre-existing CKD.
• Nicotine and other toxins in tobacco smoke induce renal damage, inflammation, and fibrosis.
• Smokers exhibit a higher risk of developing hypertension and proteinuria, key factors in CKD progression.
• Evidence supports a causal relationship between smoking and the onset and advancement of renal disease, including progression to ESRD.

Conclusions:

• Smoking is a significant, modifiable risk factor for kidney disease progression and ESRD.
• Nephrologists and all physicians must prioritize smoking cessation interventions for patients with or at risk of kidney disease.
• Addressing smoking is crucial for preserving renal function and reducing the burden of kidney disease.
