Authors' conclusion

Immunocompromised patients with acute respiratory failure face a significant risk of developing AKI, driven by a combination of factors such as their underlying conditions and disease severity. In contrast, the direct impact of invasive mechanical ventilation appears to be limited, suggesting that mechanical ventilation may not be a primary driver of AKI in this vulnerable patient population.
