Randomized controlled trials in systemic lupus erythematosus: what has been done and what do we need to do?

Lupus
J Schiffenbauer, L S Simon

Abstract

The study of systemic lupus erythematosus (SLE) is a challenging undertaking. It is difficult to assess outcomes in SLE randomized controlled trials (RCTs), and this is illustrated by the lack of new therapies approved for use in lupus. In a disease that is waxing and waning, and requires constantly changing medications, identifying treatment effects of new therapies may be difficult, and the use of potentially toxic therapies requires a rigorous understanding of the benefit to risk ratio. Some issues that need to be considered by the investigator in designing these studies include: 1) should the trial focus on patients with active or inactive disease; 2) which of the measures of disease activity should be used or should prevention of flares be examined; 3) should the study focus on defined organ specific endpoints or utilize one of the available disease activity indices to identify changes in disease activity; 4) should the trial be a superiority trial or an equivalence trial. This review summarizes the critical issues involving the design of studies in lupus and provides the reader with suggestions and recommendations for consideration before embarking on trials in this area.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
