The Potential for Repurposing Anti-TNF as a Therapy for the Treatment of COVID-19.

Coronavirus disease 2019 (COVID-19) currently has few effective treatments. Given the uncertainty surrounding the effectiveness and uptake of a vaccine, it is important that the search for treatments continue. An exaggerated inflammatory state is likely responsible for much of the morbidity and mortality in COVID-19.

Effectiveness and safety of endothelin receptor antagonists, alone and in combination therapy, in the pulmonary arterial hypertension-connective tissue disease subtype: A systematic review and meta-analysis.

Introduction: There is limited information regarding the effectiveness of endothelin receptor antagonists (ERA) in patients with connective tissue disease-pulmonary arterial hypertension (CTD-PAH), a condition that is characterized by poorer clinical outcomes compared to other PAH subtypes.

Objective: To conduct a systematic review and meta-analysis of the effectiveness and safety of ERA in CTD-PAH.

Methods: A literature search, using MEDLINE, COCHRANE, CINAHL and EMBASE databases was conducted, from inception to May 2019 to identify randomized control studies of ERA, as monotherapy or in combination with phosphodiesterase type 5 inhibitors (PDE5i), in CTD-PAH.
