[Challenges and potential solutions in first-line treatments for immune thrombocytopenia in adults].
The first line treatment of immune thrombocytopenic purpura (ITP) is well established and based on short course of corticosteroids associated with intravenous immunoglobulins (IVIg) for the most severe forms. Predniso(lo)ne is the corticosteroid agent usually given but dexamethasone appears as an alternative. Some guidelines recommend to use dexamethasone as first line when a rapid increase of platelet count is required. ⋯ Other therapeutic options such as anti FcRn monoclonal antibodies or recombinant FcγR currently in development for ITP could be an option in the future. In newly diagnosed ITP, we unfortunately lack robust predictive risk factors of severity and chronic outcome. Identifying such factors could be helpful for considering the early use of some treatments which are commonly used as second or third line.

Since Hippocrates, the cornerstone of medical practice has been the doctor-patient relationship. The question here is whether these basic principles are still compatible with this unusual COVID-period. This pandemic represents a serious threat to human health, leading to profound changes in behavior in daily life but also in health care. ⋯ The historical point-of-view helps us to keep in mind previous experiences, and the philosophical perspective helps to contextualize this unedited situation. We should stop briefly our daily rush to put these considerations into perspective to overcome these challenges. Nothing is as effective as trust: let's rebuild it.

Multirefractory immune thrombocytopenia (ITP) is defined by the absence of response to TPO receptor agonists, rituximab and splenectomy (or contraindicated or refused) and the need of treatment. The approach to multirefractory ITP must be systematic and firstly involves reconsidering the diagnosis. ⋯ Therapeutic management is complex and is based on the combination of treatments. New treatments are being developed.

Secondary forms of immune thrombocytopenia (ITP) represent approximately 20% of all ITP cases in adulthood and this rate increases with age. Since some causes may influence both the prognosis and outcome but also the management of ITP, a minimal workup must be performed at ITP diagnosis to look for an associated or underlying cause. Among adults, B-cell lymphomas and mainly chronic lymphocytic leukemia, systemic auto-immune diseases such as systemic lupus or primary immunodeficiencies mainly represented by common variable immunodeficiency are the most frequent causes of secondary ITP. Whereas first-line therapy used for secondary ITP is usually similar to the one commonly used in primary ITP and relies mostly on corticosteroids±intravenous immunoglobulin according to the severity of bleeding, second and third-line treatments must take into account the type and degree of activity of the underlying disease.
