The level of procalcitonin in the blood stream of healthy individuals is below the limit of detection (0.01 μg/L) of clinical assays. [3] The level of procalcitonin rises in a response to a pro-inflammatory stimulus, especially of bacterial origin. It is therefore often classed as an acute phase reactant. [4]
Inflammatory cytokines play a role in initiating the inflammatory response and to regulate the host defence against pathogens mediating the innate immune response. [4] Some inflammatory cytokines have additional roles such as acting as growth factors. [5] Pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α also trigger pathological pain ...
Positive acute-phase proteins serve (as part of the innate immune system) different physiological functions within the immune system.Some act to destroy or inhibit growth of microbes, e.g., C-reactive protein, mannose-binding protein, [3] complement factors, ferritin, ceruloplasmin, serum amyloid A and haptoglobin.

Chronic systemic inflammation (SI) is the result of release of pro-inflammatory cytokines from immune-related cells and the chronic activation of the innate immune system.It can contribute to the development or progression of certain conditions such as cardiovascular disease, cancer, diabetes mellitus, chronic kidney disease, non-alcoholic fatty liver disease, autoimmune and neurodegenerative ...
Nicotinamide (a form of vitamin B 3) is a potent inhibitor of proinflammatory cytokines. [8] [9] Low blood plasma levels of trigonelline (one of the metabolites of vitamin B3) have been suggested for the prognosis of SARS-CoV-2 death (which is thought to be due to the inflammatory phase and cytokine storm).
Dinoprostone as a vaginal suppository is contraindicated for women with acute pelvic inflammatory disease or active disease of the cardiovascular, respiratory, hepatic, or renal systems. Caution is required for people with a history of cervical malignancy, hypo- or hypertension, anemia, epilepsy, jaundice, asthma, or pulmonary diseases.
A systematic review of 32 randomised controlled trials with 6,078 participants with acute respiratory infections compared procalcitonin (a blood marker for bacterial infections) to guide the initiation and duration of antibiotic treatment, against no use of procalcitonin. Among 3,336 people receiving procalcitonin-guided antibiotic therapy ...
