Observational Study
The appropriateness of penicillin allergy de-labelling by non-allergist clinical ward teams.
We aimed to assess the appropriateness of penicillin allergy (PenA) assessment conducted by clinical teams and to review the safety of subsequent exposure of these patients to penicillin. ⋯ Using the allergy risk tool, most patients with PenA records were exposed to penicillin appropriately. However, patients meeting high-risk criteria were also exposed to penicillin when the tool excluded them. PenA assessment needs to be carried out with appropriate training and governance structures in place.

Inpatient treatment of hyperkalaemia with insulin and dextrose can be complicated by iatrogenic hypoglycaemia. We sought to assess the incidence of hypoglycaemia in hospitalised patients with renal disease and assess the impact of the introduction of a local guideline incorporating the use of sodium zirconium cyclosilicate (SZC) for patients with moderate hyperkalaemia. After establishing a significant burden of hypoglycaemia in the initial observation period, a requirement for hourly capillary blood glucose monitoring (for up to 6 h) following the administration of insulin for hyperkalaemia was incorporated into the guidelines. The two-fold introduction of SZC alongside changes in patient care after the administration of insulin/dextrose resulted in more appropriate use of insulin/dextrose, as well as a significant (73%) reduction in the iatrogenic burden of hypoglycaemia (P = 0.04).

The gap in excess mortality between patients with and without diabetes has not decreased over time. The aim of this study was to investigate the determinants of mortality after acute myocardial infarction (AMI) in patients with diabetes and without diabetes in a contemporary population. A retrospective analysis of a cohort of 266 patients with a diagnosis of AMI during 2022 was carried out. ⋯ Plasma glucose was independently associated with peak troponin in patients both with and without diabetes. These data suggest that patients living with diabetes and with a low eGFR warrant more aggressive risk reduction and use of nephroprotective medications. Further studies are needed to assess whether early blood glucose control improves cardiovascular outcomes in all patients with AMI.

We report a case series of two patients with chronic kidney disease (CKD) who developed erythropoietin-induced pure red cell aplasia following a change in erythropoietin preparation. Both patients responded well to immunosuppressive treatments, but unfortunately developed severe infections as a result of being immunosuppressed.
