Persistent NK cell deficiency associated with pulmonary cryptococcosis.

We describe pulmonary cryptococcosis in a 28-year-old previously healthy man. Exhaustive immunological investigations revealed a primary NK cell deficiency associated with a secondary impaired anti-Cryptococcus CD8 lymphocyte response and the expansion of a CD8Vβ14 + T cell clone. This case illustrates the potential role of NK cells in immunity against Cryptococcus.

Efficacy of Rituximab Outlasts B-Cell Repopulation in Multiple Sclerosis: Time to Rethink Dosing?

Background And Objectives: Patients with multiple sclerosis (PwMS) receiving extended dosing of rituximab (RTX) have exhibited no return of disease activity, which suggests that maintenance of deep depletion of circulating B cells is not necessary to maintain the efficacy of RTX in MS.

Methods: This was a prospective monocentric observational study including all consecutive PwMS who started or continued RTX after 2019, when the medical staff decided to extend the dosing interval up to 24 months for all patients. Circulating B-cell subsets were monitored regularly and systematically in case of relapse.

[Promoting responsible self-medication in the context of Parkinson's disease: Development of a practical guide for drug-drug interactions and assessment by patients and community pharmacy professionals].

Context: Parkinson disease is a neurodegenerative disorder characterized by motor and non-motor symptoms. Symptomatic treatment is based on dopaminergic medications. In case of self-medication practices, there may be drug-drug interactions between over-the-counter medication and dopaminergic medications.

The clinical meaning of levodopa equivalent daily dose in Parkinson's disease.

Levodopa (L-dopa) remains the basis of pharmacological treatment of Parkinson's disease (PD). However, L-dopa therapy is associated with the development of complications and presents major challenges in the long-term treatment. Thus, other medications may be suggested to delay and/or reduce the doses of L-dopa in order to prevent complications.
