One in five hospitalized patients suffers acute kidney injury (AKI). Depending on its severity, AKI is associated with an up to 15-fold increased risk of mortality and constitutes a major risk factor for subsequent cardiovascular events and for the development of chronic kidney disease. This concise review summarizes recently published studies, focusing on 1.) automated AKI detection using electronic health records-based AKI alert systems, 2.) renal replacement therapy and its optimal timing and anticoagulation regimen, and 3.) coronavirus disease-2019 (COVID-19) associated AKI.

COVID-19, primarily a respiratory disease, is considered a multi-systemic disease as symptom severity increases. Blood coagulation abnormalities are key features of patients with severe symptoms and indicative of the high risk of both venous and arterial thromboembolism in COVID-19. ⋯ However, the optimal dosage of anticoagulation is still debated. In this article, we provide an overview of the current state of knowledge about COVID-19-associated coagulopathy and discuss clinical therapeutic consequences.

Givosiran is a small synthetic double-stranded siRNA (small interfering RNA) conjugated with N-acetyl-galactosamine (GalNAc) for specific hepatocyte targeting via the asialoglycoprotein receptor. A prospective randomized multicenter study (Envision) demonstrated the clinical efficacy of monthly subcutaneous injection of Givosiran for the prevention of attacks of acute hepatic porphyria (AHP). This leads to highly selective transcriptional inhibition of the key hepatic enzyme, aminolaevulinate synthase 1, that is overexpressed in AHP. ⋯ This innovative guided siRNA therapy has opened up the possibility to selectively inhibit the expression of any hepatocyte gene whose overexpression that causes pathology, which can be considered a milestone development in hepatology. However, currently this treatment with givosiran is very costly. Moreover, since some patients experience worsening of kidney function and elevated aminotransferases, monthly monitoring of these parameters is necessary in the first half year of treatment.

Case Reports[Long-lasting souvenir from Cameroon - Persistent, massive hypereosinophilia in amicrofilaremic infection with Loa loa].
Diagnosis of a polysymptomatic, rare parasitosis requires collaboration of internal specialists, tropical disease specialists, parasitologists and dermatologists. ⋯ Parasitic diseases like L. loa infections are extremely rare in Europe but should be considered as differential diagnosis at an early stage when patients present with appropriate travel history and clinical findings. There is a lack of standardized therapy and follow-up recommendations. A precise recording of all new diagnoses with therapy progress/response should be established in an international registry.

Right heart catheterisation is a frequently used procedure in cardiology and intensive care medicine, especially for the differential diagnosis of pulmonary hypertension, shunt diagnostics and accurate calculation of the important haemodynamic parameters. Various catheters are available for the examination; the most common and safest is the use of a Swan-Ganz catheter. The complete examination includes probing of the right atrium, right ventricle, pulmonary artery and pulmonary capillary bed. In this "step-by-step" article, the authors discuss the practical aspects of this method.
