Background: Undiagnosed and untreated atherosclerotic renal artery stenosis (ARAS) can result in end-stage kidney disease (ESKD). To obtain an accurate diagnosis, it is crucial to recognize the symptoms signs suggesting (RAS) perform appropriate diagnostic treatment procedures afterward. Case Presentation: We present a case of 60-year-old female patient with hypertensive crisis, acute heart failure (HF), pulmonary edema as initial injury (AKI) caused by right RAS left occlusion presence...

Background: Chronic kidney disease (CKD) is a progressive, irreversible impairment of function due to various etiologies. Numerous studies have shown that sodium-glucose cotransporter-2 inhibitors (SGLT2i) slow the progression CKD, their pleiotropic effects. Therefore, there has been an increase in interest effects not only on but also other parameters patients with CKD. The aim study was examine SGLT2i serum lipid values and CKD undergoing treatment. Methods: This retrospective data...

To prevent organ rejection, renal transplant (RT) recipients must take immunosuppressive medicines, which make them more susceptible to infections such as tuberculosis (TB). Hepatotoxicity, can vary from asymptomatic increased liver enzymes severe failure, is the most prevalent side effect of first-line antituberculosis (AT) drugs. Treating TB in RT patients involves unique concerns since AT medications might interact with medications, potentially reducing efficacy or increasing toxicity. A...
