Nitric oxide (NO) levels and pulmonary function tests (PFTs) were evaluated in children undergoing hemodialysis (HD). Elevated NO and altered PFTs were observed, suggesting NO may indicate worsening respiratory health in these patients.
Area of Science:
- Nephrology
- Pulmonology
- Biochemistry
Background:
- The link between lung and kidney health is significant.
- The effect of nitric oxide (NO) on respiratory function in renal patients remains unclear.
Purpose of the Study:
- To assess pulmonary function tests (PFTs) and nitric oxide (NO) levels in children with end-stage renal disease on hemodialysis (HD).
- To investigate the correlation between PFTs, NO levels, and dialysis parameters.
Main Methods:
- Compared 20 children on HD with 20 controls.
- Conducted spirometry for PFTs (FVC, FEV1, FEV1/FVC, FEF25%-75%, PEF) before and after HD.
- Measured arterial blood gas (ABG) and NO levels.
Main Results:
- Patients on HD showed significantly different NO levels and most PFTs compared to controls.
- A significant negative correlation was found between NO and some PFTs in the patient group.
- Hemodialysis improved Forced Vital Capacity (FVC) but did not significantly alter NO levels or other PFTs.
Conclusions:
- Nitric oxide (NO) may play a role in the decline of respiratory function in children with end-stage renal disease.
- NO could serve as a potential biomarker for clinical deterioration in these patients.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Factors Affecting Renal Clearance: Drug's Physicochemical Properties and Plasma Levels
One important factor is the drug's molecular size. The kidneys readily excrete smaller molecules below 300 Daltons (Da). On the other hand, molecules weighing between 300 and 500 Da are excreted through both urine and bile. Larger molecules above 500 Da tend to be excreted...
