Chronic kidney disease (CKD) affects many adults worldwide. Persistent low-grade inflammation is a substantial factor in its development and progression and has correlated with increased mortality and cardiovascular problems. This low-grade inflammation is a product of dysregulation of the normal balance between pro- and anti-inflammatory markers. Various factors such as increased innate immune system activation, reactive oxygen species production, periodontal disease, dysregulation of anti-inflammatory systems and intestinal dysbiosis result in the dysregulation of this balance. Furthermore, this low-grade inflammation has down-effects such as hypertension, renal fibrosis and acceleration of renal function decline. Moreover, low-grade inflammation over time has been linked to malignancy in CKD. As CKD progresses, many patients require dialysis, which has a negative bidirectional relationship with persistent inflammation. Treatment options for inflammation in CKD are vast, including cytokine inhibitors, statins and diets. However, more research is needed to create a standardized management plan. In this review, we will examine the normal physiology of the kidney and its relationship with the immune system. We will then delve into the pathology behind persistent inflammation, the various causes of inflammation, the downstream effects of inflammation, dialysis and potential treatments for inflammation in CKD.
Acute Kidney Injury (AKI), a common and severe complication following burn injuries, presents a significant challenge due to its broad clinical manifestations and diverse etiologies. AKI, previously known as acute renal failure, can present abruptly following burns or thermal injuries, causing detrimental health outcomes such as progressive kidney dysfunction, increased hospital length of stay (LOS), and requirement of renal replacement therapy (RRT). AKI affects the maintenance of homeostasis of fluid and electrolytes, elimination of metabolic wastes and by-products, and acid-base balance. Aggressive nutritional support is particularly necessitated in burn patients to prevent protein-energy wasting (PEW) and a negative nitrogen balance. Understanding the pathogenesis of AKI in burns and improving its prevention and early diagnosis are active areas of research in this field. Despite the potential benefits, the optimal timing and threshold for RRT initiation in burn patients with AKI remain unclear, warranting further studies. Ongoing investigations focus on refining RRT techniques, evaluating biomarkers for early detection of AKI, and exploring adjunctive therapies to enhance renal recovery. The aim of this study is to review the etiology, diagnostic tools, and interventions that improve outcomes associated with AKI in burn-related settings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
