COVID-19 does not impact on outcome of myeloma patients infected while undergoing autologous stem cell transplantation.

Here we report two cases of myeloma patients who became positive for SARS-CoV-2 infection during the acute phase of autologous stem cell transplant. Both patients were promptly treated with monoclonal antibodies and remdesivir, and, despite the profound neutropenia and lymphopenia, they did not develop respiratory failure and they remained paucisymptomatic during the entire period of aplasia. Neutrophil engraftment took place as expected and the patients were discharged quickly and did not experience adverse effects after discharge.

Hypersensitivity reactions to iodinate contrast media in Italy: a retrospective study. Characteristics of patients and risk factors.

The purpose of the study was to describe the characteristics of patients experiencing hypersensitivity reactions (HRs) to iodinated contrast media (ICM) in a large Italian population and to investigate potential risks factors in order to obtain a risk stratification, helpful in the management of these patients. Data of 407 patients investigated in 9 Italian Allergy Centers for suspected HRs to ICM were analyzed and compared with a control group of 152 subjects that tolerated one or more ICM-enhanced examinations. The univariate and multivariate logistic regression model was used to evaluate associated factors.

Delayed corticosteroid hypersensitivity: a clinical management proposal.

Different clinical pictures are related to corticosteroids (CS) non immediate hypersensitivity and the frequency of these reactions can be underestimated. The classification of CS in 3 groups and the identification of two patient's profiles has been proposed by Baeck to help clinicians in the management of these cases. Data of 14 patients with clinical history of delayed reactions to various CS and positive skin test and/or oral challenge are retrospectively analyzed.

Assessing clinical and psychological features: who are patients showing a nocebo re-action during the drug challenge test?

The nocebo reaction, namely the undesirable effect of an inert substance (placebo), is a phenomenon rarely investigated in literature. A better knowledge of this reaction may help clinicians in the management of these patients in clinical practice. Patients with drug adverse reactions (ADR) undergoing the drug challenge test are an ideal model for studying the nocebo effect, and the study aims to investigate their clinical and psychological features.

Management of suspected immediate perioperative allergic reactions: an international overview and consensus recommendations.

Suspected perioperative allergic reactions are rare but can be life-threatening. The diagnosis is difficult to make in the perioperative setting, but prompt recognition and correct treatment is necessary to ensure a good outcome. A group of 26 international experts in perioperative allergy (anaesthesiologists, allergists, and immunologists) contributed to a modified Delphi consensus process, which covered areas such as differential diagnosis, management during and after anaphylaxis, allergy investigations, and plans for a subsequent anaesthetic.
