Evaluation of Skin Tests in Biotherapy Allergies

Biotherapies are biological (extracted from an organism or living tissue) or biotechnological drugs used in the treatment of multiple conditions, such as autoimmune inflammatory diseases, cancers, and hematologic diseases. In recent years, these biotherapies have notably emerged in the treatment of cancers and hematologic disorders. As such, most patients with cancers or hematologic diseases will likely receive a biotherapy as part of their care pathway. These biotherapies are associated with various side effects, including hypersensitivity or allergic reactions, which are often poorly characterized in clinical trials. These reactions manifest as symptoms without specific dermatologic or allergologic semiology (such as itching, erythema, shortness of breath, sometimes digestive issues, or discomfort, and in some cases, an anaphylactic reaction). Unlike other treatments, such as antibiotics and neuromuscular blockers, there are currently no guidelines on the concentrations to use in skin tests for biotherapies. We propose conducting prospective clinical research to scientifically establish the concentrations to be used when investigating hypersensitivity to a biotherapy, in line with best practice recommendations for drug skin testing.

Evaluation of Chemotherapy-induced Cognitive Disorders During the Treatment of Hematological Malignancies

Chemotherapy-induced cognitive disorders, such as memory problems, slowness of execution, inability to concentrate, and language difficulties, are sequelae that occur in patients undergoing chemotherapy or who have received chemotherapy. These symptoms lead to a degradation of the patients' quality of life and can have a significant social and familial impact. They are most commonly described in solid oncology, particularly in patients with breast cancer. Data about patients with hematological malignancies are scarce, but they seem to show the same phenomenon as in solid oncology. Indeed, many chemotherapies are used both in hematology and solid oncology and may therefore cause similar effects on cognition. Additionally, due to their mechanism of action, some chemotherapies specifically used in hematology could induce cognitive disorders. Hematology-treated patients are probably also affected by these disorders and may consequently experience a reduced quality of life. The objective of this study is to assess the changes in cognitive functions in patients receiving chemotherapy for the treatment of hematological malignancies, using neuropsychological tests and a self-administered questionnaire, compared to a control group, as well as their potential impact on quality of life, fatigue, anxiety, and depression.
