Upper Respiratory Tract Infection among Dialysis Patients

Area of Science:

• Nephrology
• Infectious Diseases
• Public Health

Background:

• Upper respiratory tract infections (URTIs) are common but generally benign in the general population.
• Dialysis patients represent a high-risk group for URTI complications, with unknown morbidity and mortality rates.
• Understanding URTI impact in dialysis patients is crucial for risk stratification and management.

Purpose of the Study:

• To determine the incidence, morbidity, and mortality of URTIs in dialysis patients.
• To compare URTI outcomes in dialysis patients versus the general population.
• To identify common pathogens and their impact on URTI severity in dialysis patients.

Main Methods:

• Retrospective cohort study of chronic dialysis patients diagnosed with URTI.
• Data collected from Meir Medical Center, Kfar Saba, Israel, during the 2014-2015 winter season.
• Comparison with general population data for the same period.

Main Results:

• 40 dialysis patients were eligible; average age 66.1 years with high comorbidity.
• Influenza A was the most frequent pathogen; complications included pneumonia (20%), hospitalization (47.5%), and respiratory failure (12.5%).
• Dialysis patients experienced significantly higher pneumonia incidence (20% vs. 4.4%) and a 10% overall mortality rate.

Conclusions:

• URTIs pose a significantly greater threat to dialysis patients compared to the general population.
• Dialysis patients face substantially higher rates of URTI-related complications and mortality.
• Influenza A infection in dialysis patients is associated with a poorer prognosis, highlighting the need for targeted prevention and treatment strategies.
