Abstract
-
BACKGROUND: Intraarticular local anesthetic injection has been therapeutically applied
for pain control in various arthritis patients. However, little physiologic effects of
local anesthetics on their tissue were known. This study was conducted to determine its
effects on the cell proliferation and matrix metallopro- teinases (MMP) production of
cultured fibroblast like synoviocytes (FLS) derived from synovial tissues of rheumatoid
arthritis patients.
METHODS
Bupivacaine with varying concentrations 0 (control), 0.1, 0.25, 0.5% was applied
to experimental cell groups growing as monolayers in culture plates for varying durations
0 (control), 30, 90, 180 seconds in the presence and absence of interleukin-1 J.
RESULTS
No statistical significances were noted in thymidine incorporation between
0, 30, 90 and 180 seconds exposure groups with 0.5% bupivacaine after 1 day and 2 days.
Thymidine incorporation between 0, 0.1, 0.25, 0.5% exposure groups 1 day and 2 days after
90 seconds exposure did not show any differences. After exposure to bupivacaine, there
were statistieally significant increases in MMP-1 (p 0.025) and MMP-3 productions (p 0.000)
of FLS in the absence of IL-1 p, but no differences among the groups in the presence
of IL-1 p.
CONCLUSION
We concluded that in this short-term in vitro study, bupivacaine does not have
injurious effect on cultured rheumatoid artbritic joint tissues. The long-term effect
cannot be known from this investigation.
