In quite a few patients with bipolar disorder there is no real alternative to lithium treatment despite impaired kidney function. Is it possible to continue lithium treatment despite kidney malfunction by changing dosage and/or frequency of administration? We report on a 65-year-old woman suffering from bipolar-I disorder who had been on lithium treatment for many decades. While on lithium, the glomerular filtration rate (GFR) decreased constantly. A decision had to be made whether to switch to a more tolerable o.d. administration or to taper off lithium. With a single dose at bedtime, the serum levels remained stable; however, kidney function unfortunately did not improve. A relevant increase of GFR above the level of 60 mL/min/1,73 m was only achieved after a 50% dose reduction leading also to a substantial decrease of lithium serum levels. A kidney protective lithium application in patients with reduced renal function is like sailing between Scylla and Charybdis.

Background: Lately, numerous researches have portrayed stress hyperglycemia ratio (SHR) is predominantly connected with short-term adverse prognosis among individuals who have acute coronary syndrome. Nevertheless, the relation of SHR with prolonged effects and the value of SHR in predicting in coronary artery disease (CAD) patients with or lacking chronic kidney disease (CKD) remain unclear. The present study was designed to elucidate the relation of SHR with prolonged prognosis and the value of SHR in predicting the long-term all-cause and cardiovascular death of CAD patients with CKD or non-CKD.

Background: Megakaryocytes are traditionally recognized as cells responsible for platelet production. However, beyond their role in thrombopoiesis, megakaryocytes also participate in inflammatory responses and regulate immune system functions. Sepsis, characterized by life-threatening organ dysfunction due to a dysregulated response to infection, prominently features coagulopathy, severe inflammation, and immune dysfunction as key pathophysiological aspects.

Background: The impact of protein-bound uremic toxins, specifically indoxyl sulfate (IS) on peritoneal dialysis (PD) complications remains controversial. This study aimed to explore the link between serum total IS (tIS) levels, proinflammatory cytokines in serum and peritoneal dialysis effluent (PDE), and PD technique survival.
Methods: In this prospective cohort study, 84 patients were followed up for three years and analyzed.

Background/aim: Immune checkpoint blockade has achieved great success as a targeted immunotherapy for solid cancers. However, small molecules that inhibit programmed death 1/programmed death ligand 1 (PD-1/PD-L1) binding are still being developed and have several advantages, such as high bioavailability. Previously, we reported a novel PD-1/PD-L1-inhibiting small compound, SCL-1, which showed potent antitumor effects on PD-L1 tumors.
