Natural cannabinoids suppress the cytokine storm in sepsis-like in vitro model.

Natural cannabinoids may have beneficial effects on various tissues and functions including a positive influence on the immune system and the inflammatory process. The purpose of this study was to investigate the effects of natural cannabinoids on the production of pro-inflammatory cytokines by lipopolysaccharide (LPS)-stimulated whole human blood cells. Levels of the pro-inflammatory cytokines interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were measured before and after exposure of LPS-stimulated whole blood to different concentrations of Cannabidiol (CBD) or a combination of CBD and Tetrahydrocannabinol (THC) extract.

Acute amiodarone liver toxicity likely due to ischemic hepatitis.

Background: Hepatotoxicity due to intravenous amiodarone (HIVAD) is a rare side effect with a distinct pattern of enzyme disturbances compared to liver damage from oral amiodarone. Intravenous amiodarone is administered for acute arrhythmias often causing heart failure. The enzyme abnormalities and clinical setting are very similar to that of ischemic hepatitis, a far more common condition.

Acute renal failure as the presenting symptom of pericardial effusion.

Pericardial effusion from any cause may lead to decreased cardiac output and blood pressure, causing heart failure and reduced renal blood flow. Although pericardial effusion is not uncommon, it is usually not associated with hemodynamic compromise unless the effusion causes cardiac tamponade. Acute renal failure resulting from pericardial effusion is surprisingly rare, with only six cases described to date.

Healthcare associated infective endocarditis: a distinct entity.

The terms hospital- and community-acquired infections do not cover any longer the full spectrum of acquisition of infection. Consequently, the term healthcare associated infection (HCA) has been recently introduced. In order to examine the applicability of 'HCA infection' to patients with infective endocarditis (IE), 125 episodes of culture-positive IE were categorized into 3 groups of acquisition.

Effect of a four-week course of interleukin-10 on cytokine production in a placebo-controlled study of HIV-1-infected subjects.

Interleukin (IL)-10 suppresses synthesis of the pro-inflammatory cytokines tumor necrosis factor (TNF)alpha, IL-1beta, and interferon (IFN)gamma. Since pro-inflammatory cytokines have been implicated in the production of human immunodeficiency virus type 1 (HIV-1), cytokine synthesis in whole blood cultures were determined during a 4-week course of subcutaneous IL-10 injections in 33 HIV-1-infected patients. Patients were randomized into four groups: placebo (nine), IL-10 at 1 microg/kg/day (nine), IL-10 at 4 microg/kg/day (six) and IL-10 at 8 microg/kg three times per week (nine).
