The inflammatory component of diabetic kidney disease has become of great interest in recent years, with genetic and epigenetic variants playing a fundamental role in the initiation and progression of the disease. Cells of the innate immune system play a major role in the pathogenesis of diabetic kidney disease, with a lesser contribution from the adaptive immune cells. Other components such as the complement system also play a role, as well as specific cytokines and chemokines. The inflammatory component of diabetic kidney disease is of great interest and is an active research field, with the hope to find potential innovative therapeutic targets.

Diabetic kidney disease (DKD) is a highly prevalent condition worldwide. It represents one of the most common complications arising from diabetes mellitus (DM) and is the leading cause of end-stage kidney disease (ESKD). Its development involves three fundamental components: the hemodynamic, metabolic, and inflammatory axes. Clinically, persistent albuminuria in association with a progressive decline in glomerular filtration rate (GFR) defines this disease. However, as these alterations are not specific to DKD, there is a need to discuss novel biomarkers arising from its pathogenesis which may aid in the diagnosis, follow-up, therapeutic response, and prognosis of the disease.

Contexto: la enfermedad renal diabética (ERD) es la primera causa a nivel mundial de enfermedad renal crónica (ERC) e impacta directamente en el riesgo cardiovascular y mortalidad de los pacientes con diabetes mellitus (DM). La finerenona, un antagonista selectivo del receptor mineralocorticoide (ARM), ha sido descrito en diversos estudios recientes como un fármaco que contribuye a la reducción de la progresión de la ERD y la disminución del riesgo cardiovascular, con un adecuado perfil de seguridad. Objetivo: realizar una revisión de la literatura sobre el impacto de la finerenona en la progresión del daño renal y el riesgo cardiovascular en los pacientes con ERD. Metodología: se realizó una búsqueda sistemática en diversas fuentes: PubMed (Medline, Biblioteca del Congreso de los Estados Unidos), Science Direct, Scopus, Embase y Lilacs; la búsqueda fue restringida a referencias en idioma español e inglés, sin límites en la fecha de publicación. Se utilizaron las siguientes palabras clave en el idioma inglés: diabetic renal disease, chronic kidney disease, diabetes mellitus, spironolactone, eplerenone, finerenone, mineralocorticoid receptor antagonist y sus correspondientes versiones en español. Resultados: Las referencias encontradas en la búsqueda fueron revisadas entre los diferentes autores para, posteriormente, proceder a realizar la elaboración del documento. Conclusiones: la finerenona es un medicamento que brinda cardio y nefroprotección en pacientes con ERD de fenotipo albuminúrico.

Background. The syndrome of tubulointerstitial nephritis and uveitis (TINU) is a rare oculorenal condition, mainly seen in children and women. The underlying cause of this disease is unknown. Case Presentation. We report a 24-year-old male without any past medical history, diagnosed with bilateral uveitis and azotemia. Biopsy revealed tubulointerstitial nephritis, consistent with TINU syndrome. Fluorescein angiogram revealed peripheral retinal vasculitis. Discussion. TINU is a rare disorder that needs to be distinguished from sarcoidosis, Sjogrens disease, and tuberculosis. Treatment is indicated in patients with progressive renal insufficiency, consisting of steroid therapy. Most patients recover kidney function. Its early recognition is important to offer the best chance of organ preservation.

Obesity is a risk factor for the development and progression of CKD, which has been shown in numerous studies. The mechanism of how this occurs is not completely understood, but several putative mechanisms proposed via adiposity, include low adiponectin high leptin and resistin, causing inflammation, insulin resistance, RAAS activation and oxidative stress, leading to CKD; in addition, it also causes diabetes mellitus, hypertension, and cardiovascular disease. Obesity is a persistent inflammatory state, and inflammation has been shown to play an important role in the development and progression of diabetic kidney disease, hence controlling obesity has become a key component as a preventative strategy in the development of kidney disease.
