Acute kidney injury in critically ill patients and intestinal dysbiosis

Introduction: Acute kidney injury (AKI) occurs in critically ill patients with significant impact on their morbidity and mortality. The sudden reduction in renal function affects the function of other organs, comprising the intestine, inducing intestinal dysmicrobia, which reciprocally worsens the course of AKI and may also lead to the development of chronic nephropathy. Purpose: Pathophysiology of AKI, sepsis and intestinal dysmicrobia in a critical patient with impact on the development of the disease and other organ systems with possibilities of its positive influence by nutritional measures. Conclusion: Critically ill patients especially in septic status complicated by AKI are prone to complications such as intestinal dysmicrobia, secondary sepsis and immunodeficiency. Treatment of the underlying disease and its complications along with nutritional support helps to improve the clinical outcome of this group of patients.
