Summary
The pan-immune-inflammation value (PIV) is linked to higher mortality in osteoarthritis patients. Higher PIV indicates an increased risk of death from all causes and cardiovascular disease in adults with OA.
Area of Science:
- Rheumatology
- Cardiovascular Disease
- Inflammation Research
Background:
- Systemic inflammation is a key factor in osteoarthritis (OA) progression.
- The pan-immune-inflammation value (PIV) is an emerging marker for systemic inflammation.
Purpose of the Study:
- To investigate the association between PIV and mortality in patients with OA.
- To explore the relationship between PIV and both all-cause and cardiovascular disease (CVD) mortality.
Main Methods:
- Utilized data from the National Health and Nutrition Examination Survey (1999-2018).
- Calculated PIV using platelet, neutrophil, monocyte, and lymphocyte counts.
- Assessed OA via self-report and mortality through the National Death Index.
Main Results:
- A total of 3903 OA participants were analyzed.
- Higher PIV levels were significantly associated with increased all-cause and CVD mortality.
- A threshold effect was observed, with significant associations appearing after an inflection point.
Conclusions:
- Elevated PIV is associated with greater mortality risk in US adults with OA.
- Further research is required to determine PIV's utility in clinical mortality prediction models.

Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
Acute Inflammation II: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
