Nonsteroidal antiinflammatory drug-induced small intestinal inflammation and blood loss. Effects of sulfasalazine and other disease-modifying antirheumatic drugs

Arthritis and Rheumatism
J HayllarI Bjarnason


To identify the source of intestinal blood loss in rheumatoid arthritis patients being treated with nonsteroidal antiinflammatory drugs (NSAIDs) and assess the response to sulfasalazine and other disease-modifying antirheumatic drugs (DMARDs). Intestinal inflammation, blood loss, and gastroduodenal damage, and the response to treatment with DMARDs, were assessed in 46 patients taking NSAIDs. Intestinal inflammation and blood loss correlated significantly with one another (r = 0.43, P < 0.003), but not with the macroscopic or microscopic appearance of the gastroduodenal mucosa. Sulfasalazine reduced both intestinal inflammation and blood loss, whereas the other DMARDs did not. The small intestine is the main site of mild chronic blood loss in patients receiving NSAIDs, and this blood loss can be reduced with sulfasalazine treatment.

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.

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.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.
