[Acute respiratory tract infections and antibiotic prescriptions: What are patients' expectations?]
The use of antibiotics in human medicine is partly responsible for the global increase in antibiotic resistance. Significant reductions in antibiotic prescribing were realised through educational campaigns, communication training and prescribing feedback. Based on data from the cluster-randomised CHANGE-3 trial, the present analysis focuses on the question of patient expectations for an antibiotic in acute respiratory infections. ⋯ Patients still receive antibiotics more often than they actually hope for. On the part of GPs, prescriptions may still be written because of perceived pressure from patients, but this is not reflected in patient expectations. In addition to dealing openly with patients' expectations, strengthening patients' health literacy, mindful doctor-patient communication and offered opportunities for re-presentation in the case of specific diagnoses could further reduce the perceived pressure on GPs.

[Update on the diagnosis and management of SIADH and Diabetes insipidus].
Dysnatremia is a common occurrence in patients with COVID-19 and is associated with higher mortality and risk for septic conditions. The pathomechanisms are probably multifaceted, but severe hyponatremia may also occur as a result of underlying SIADH or hypocortisolism. Patients with preexisting AVP dysfunction, like SIADH or diabetes insipidus, are at high risk for severe electrolyte imbalances in the event of a COVID-19 infection. ⋯ Fluid restriction has long been considered as first-line treatment of chronic hyponatremia due to SIADH. Additional treatment with Furosemid and/or oral NaCl tablets does not improve efficacy but reduces tolerance to therapy. Copeptin-based dynamic tests show higher diagnostic accuracy in the differential diagnosis of patients with hypotonic polyuria polydipsia syndrome than the indirect water deprivation test.

[Congenital hemolytic anemias due to erythrocyte membrane and enzyme defects].
Erythrocyte membrane and enzyme defects are the most common cause of congenital hemolytic anemias in the Central European population. Diagnostics include erythrocyte morphology, special biochemical tests such as osmotic fragility (AGLT) and EMA. For enzymopenic hemolytic anemias, cost-effective biochemical analysis remains the gold standard, supplemented by molecular genetic diagnostics when appropriate. ⋯ Aplastic crises in the setting of parvovirus B19 infection occur in all congenital hemolytic anemias. Transfusion is not preventable in most cases. Iron-excreting treatment is required in the rare patients in need of chronic transfusion.

Immunosuppression is an essential prerequisite for successful transplantation. In order to reduce the sometimes-considerable side effects, combination therapies with different agents are used. This article aims to provide an up-to-date overview of immunosuppression after liver and kidney transplantation.

Autoimmune haemolytic anemia (AIHA) is defined as the immune-mediated destruction of red blood cells. In most cases, antibodies that target surface antigens on erythrocytes lead to their premature degradation in the spleen or, less commonly, in the liver. The term includes a heterogenous group of diseases, which differ largely in pathophysiology and treatment. ⋯ The IgM antibodies have their highest affinity below body temperature which is why patients experience symptoms mainly in cold-exposed body areas. Although the IgM antibodies dissolve at body temperature, the complement-loaded erythrocytes are destroyed in the liver. Therapeutic options include protection from cold and immunosuppressive agents or complement inhibition.
