INTRODUCTION: The optimal meropenem dosing regimens in critically ill patients receiving continuous renal replacement therapy (CRRT) based on pharmacokinetic and pharmacodynamic (PD) concepts are not well established. This study aimed to (1) gather the available published pharmacokinetic studies conducted in septic patients receiving CRRT and (2) to define the optimal meropenem dosing regimens in these populations via Monte Carlo simulations. METHODS: We used Medical Subject Headings "meropenem," "continuous renal replacement therapy," and "pharmacokinetics" or related terms to identify studies for systematic review...

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) are a group of microvascular thrombohemorrhagic syndromes with low incidence and high mortality, which are characterized by thrombocytopenia, microangiopathic hemolytic anemia, fever, neuropsychiatric disorders, and renal involvement. In addition, TTP has a high rate of misdiagnosis and underdiagnosis due to the lack of specific clinical manifestations. CASE REPORT: A male patient aged 47 years was admitted to our hospital with complaints of dizziness and nausea for 2 days and soy-colored urine for 1 day...

Transfusion-related acute lung injury (TRALI) is potentially life-threatening adverse reaction associated with blood transfusion and can induce perioperative pulmonary secretion. TRALI that develops during cardiopulmonary bypass (CPB) may be difficult to detect; however, the pathophysiology might manifest as derangements in CPB operations. A 79-year-old man was scheduled to undergo partial replacement of the aortic arch with CPB. Two units of red blood cells were loaded into the priming solution. Although the vital signs, including oxygenation, remained stable in the prebypass period, perfusionists noticed a decreasing trend in the venous reservoir level early in the CPB operations...

SARS-CoV-2 causes mostly mild cases. However, a considerable number of patients develop fatal acute respiratory distress syndrome due to the cytokine storm and imbalanced immune response. Several therapies depending on immunomodulation have been used, including glucocorticoids and IL-6 blockers. However, their efficacy is not perfect with all patients and patients with concomitant bacterial infections and sepsis. Accordingly, studies on different immunomodulators, including extracorporeal techniques, are crucial to save this category of patients...

INTRODUCTION: Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. As such, circulating cytokines and danger- and pathogen-associated molecular patterns (such as endotoxins) are recognized as central in the pathogenesis of sepsis and organ dysfunction. Removing these compounds by extracorporeal blood filtration, commonly considered blood purification, may improve the septic patients' condition. This study aimed to assess the vaso-inotropic support evolution over time in pediatric patients with vasoplegic shock treated with oXiris©...

RATIONALE: Acute respiratory distress syndrome (ARDS) in miliary tuberculosis (TB) remains rare, especially in pregnant women. The role of blood purification is potential in managing ARDS due to miliary TB. PATIENT CONCERNS: A 36-year-old woman presenting with difficulty breathing 6 hours before admission. She never had any constitutional symptoms due to TB. DIAGNOSES: ARDS in TB was diagnosed based on the deterioration of PaO2/FiO2, increased acute phase reactants, positive gene-Xpert, and typical chest x-ray of miliary TB...

MB-102 is a novel fluorescent tracer agent that is exclusively removed from the body by glomerular filtration. This agent can be detected transdermally to provide a real-time measurement of glomerular filtration rate at the point-of-care and is currently in clinical studies for such. MB-102 clearance during continuous renal replacement therapy (CRRT) is unknown. Its plasma protein binding (~0%), molecular weight (~372 Da) and volume of distribution (15-20 L) suggest that it may be removed by renal replacement therapies...
