Cellular and humoral responses to collagen-polyvinylpyrrolidone administered during short and long periods in humans.
Collagen, particularly type I, and its related derivatives have been extensively employed in many areas of pharmacology. The present study was performed to determine the safety of collagen-polyvinylpyrrolidone (collagen-PVP) by in vitro and in vivo studies. Sera and peripheral blood cells from healthy donors without treatment and patients treated with collagen-PVP were evaluated. We observed that the biodrug does not stimulate lymphoproliferation or DNA damage in vitro, nor does it induce human anti-porcine type I collagen or anti-collagen-PVP antibodies in vivo. Furthermore, no hepatic or renal metabolic dysfunctions were observed when collagen-PVP was administered by intradermal or intramuscular routes in short- or long-term treatments. In conclusion, the present work shows that no cellular damage or immunological adverse effects (cellular and humoral) occurred during collagen-PVP treatment, even after more than 400 weeks of consecutive administrations.
