Anti-inflammatory effect arthritis

IFN- 3 reduces the induction by inflammatory cytokines of adhesion molecules and of MHC class I and II complex on endothelial cells, a process preceding attachment and transendothelial migration of T-cells. These anti-inflammatory effects of IFN- 3 exemplify antagonistic actions of type I and type IIIFN. There is, indeed, much clinical evidence for the involvement of IFN-y in inflammatory processes - through activation of iNOS and subsequent secretion of NO - leading to the establishment of autoimmune diseases as for instance in rheumatoid arthritis. 

The pharmacy provides a wide selection of different analgesics (pain killers) and her granddaughter chose a drug with anti inflammatory effects. This medication is a great help in relieving both her pain and joint stiffness due to arthritis. The drug should be taken one pill at a time three times daily but the old lady finds that if she takes 2 pills three times daily instead of 1 she can walk better and with less pain. 

Several other modifications have been explored for the targeted delivery of SOD. Chemical modification with hydrophilic monomethoxypolyethyleneglycol polymers (MPEG) resulted in a derivative with an increased molecular weight of 130 kDa, and hence a reduced renal elimination rate. The MPEG-SOD preparations reduced arthritic lesions in a complete adjuvant arthritis model in the rat, while native SOD did not show an anti-inflammatory effect [55]. 

Leflunomide is an immunomodulatory dmg inhibiting dihydroorotate dehydrogenase, an enzyme involved in de novo pyrimidine synthesis. It has also anti-inflammatory effects. Leflunomide is able to slow progression of the disease and to cause re-mission/relief of symptoms of rheumatoid arthritis and psoriatic arthritis such as joint tenderness and decreased joint and general mobility in patients. The combined use of leflunomide with methotrexate may... 

The glucocorticoids also have powerful anti-inflammatory effects and when first introduced were considered to be the ultimate answer to the treatment of inflammatory arthritis. Although there are increasing data that low-dose corticosteroids have disease-modifying properties,... 

Other rheumatic diseases in which the corticosteroids potent anti-inflammatory effects may be useful include vasculitis, systemic lupus erythematosus, Wegener s granulomatosis, psoriatic arthritis, giant cell arteritis, sarcoidosis, and gout.

Finally, acetaminophen (paracetamol) products may provide some temporary analgesic effects in people with rheumatoid arthritis, but these products are not optimal because they lack anti-inflammatory effects. As discussed in Chapter 15, acetaminophen can be used to treat mild-to-moderate pain, but the lack of anti-inflammatory effects makes acetaminophen fall short of NSAIDs for conditions such as rheumatoid arthritis. Hence, patients with rheumatoid arthritis usually prefer the effects of NSAIDs to acetaminophen,110 and acetaminophen products are not typically used for the routine treatment of this disease. 

In addition to direct effects on genes regulating inflammation, glucocorticoids also inhibit the transcription factors that initiate synthesis of pro-inflammatory cytokines (e.g., interleukin-1, tumor necrosis factor), enzymes (e.g., COX-2, nitric oxide synthase), and receptor proteins (e.g., natural killer receptors).17,87,89 Glucocorticoids may also exert some of their effects via a membrane-bound receptor that regulates activity of macrophages, eosinophils, T lymphocytes, and several other types of cells involved in the inflammatory response.89 Consequently, glucocorticoids affect many aspects of inflammation, and their powerful anti-inflammatory effects in rheumatoid arthritis result from their ability to blunt various cellular and chemical components of the inflammatory response. 

The anti-inflammatory effect of colchicine in acute gouty arthritis is relatively selective for this disorder. Colchicine is only occasionally effective in other types of arthritis it is not an analgesic and does not provide relief of other types of pain. 

Aspirin is employed for mild to moderate pain of varied origin but is not effective for severe visceral pain. Aspirin and other NSAIDs have been combined with opioid analgesics for treatment of cancer pain, where their anti-inflammatory effects act synergistically with the opioids to enhance analgesia. High-dose salicylates are effective for treatment of rheumatic fever, rheumatoid arthritis, and other inflammatory joint conditions. 

Bisphosphonates (particularly clodronate) have been shown to have anti-inflammatory effects in animal models of rheumatoid arthritis (RA), as well as in arthritis in humans. In adjuvant- and antigen-induced arthritis in rats, clodronate suppresses the inflammatory articular lesions in the inflamed joints [29], whilst in human RA, clodronate decreases the levels of interleukin (ILJ-1, tumor necrosis factor-alpha (TNFaand /1-microglobulin in the circulation [30]. In vitro, clodronate inhibits cytokine and nitric oxide (NO) release and inducible nitric oxide synthase (iNOS) expression in macrophage-like cells.
