Acute Kidney Injury and Intestinal Dysbiosis.

ABSTRACT: Within the multiple communication pathways of the intestine-kidney axis, one of the most important pathways is the interaction between the commensals of the intestinal microbiome, through the production of short-chain fatty acids, and the segments of the nephron. These interactions maintain a perfect environmental balance. During AKI, there are negative repercussions in all organs, and the systemic interconnection is related in part to the intense inflammation and the uremic environment that this syndrome generates. For example, in the intestine, the microbiome is severely affected, with a decrease in benign bacteria that promote anti-inflammatory effects and an increase in negative, pro-inflammatory bacteria. This scenario of intestinal dysbiosis widens the inflammatory loop that favors worsening kidney function and the probability of dying. It is possible that the manipulation of the intestinal microbiome with probiotics, prebiotics and symbiotics is a reasonable therapeutic goal for AKI.

Project description:BackgroundAcute kidney injury (AKI), particularly community-acquired AKI (CA-AKI), is a major health concern globally. The International Society of Nephrology's "0 by 25" initiative to reduce preventable deaths from AKI to zero by 2025 is not achievable in low and middle income countries, such as India, possibly due to a lack of data and measures to tackle this urgent public health issue. In India, CA-AKI predisposes younger patients to hospitalization, morbidity, and mortality. This is the first multicenter, prospective, cohort study investigating CA-AKI and its consequences in India.MethodsThis study included data from patients with CA-AKI (>12 years of age) housed in the Indian Society of Nephrology-AKI registry, involving 9 participating tertiary care centers in India, for the period between November 2016 and October 2019. The etiological spectrum and renal and patient outcomes of CA-AKI at the index visit and at 1-month and 3-month follow-ups were analyzed. The impact of socioeconomic status (SES) on outcomes was also analyzed.FindingsData from 3711 patients (mean [±SD] age 44.7 ± 16.5 years; 66.6% male) were analyzed. The most common comorbidities included hypertension (21.1%) and diabetes (19.1%). AKI occurred in medical, surgical, and obstetrical settings in 86.7%, 7.3%, and 6%, respectively. The most common causes of AKI were associated with sepsis (34.7%) and tropical fever (9.8%). Mortality at the index admission was 10.8%. Complete recovery (CR), partial recovery (PR), and dialysis dependency among survivors at the time of discharge were 22.1%, 57.7%, and 9.4%, respectively. Overall, at 3 months of follow-up, mortality rate, CR, PR, and dialysis dependency rates were 11.4%, 72.2%, 7.2%, and 1%, respectively. Multivariate analysis revealed that age >65 years, alcoholism, anuria, hypotension at presentation, thrombocytopenia, vasopressor use, transaminitis, and low SES were associated with mortality at the index admission.InterpretationSepsis and tropical fever were the most common causes of CA-AKI. Presentation of CA-AKI to tertiary care units was associated with high mortality, and a significant number of patients progressed to CKD. Individuals with a low SES had increased risk of mortality and require immediate attention and intervention.FundingThis study was funded by the Indian Society of Nephrology.
