Abstract

BackgroundMethotrexate (MTX), a folic acid analogue, is used as a first-line treatment for rheumatoid arthritis (RA) since it has more therapeutic mechanisms than any other drug. Being an undeniable drug for the treatment of arthritis, even low-dose MTX provokes intestinal toxicity as a primary adverse effect and does not revive an anti-inflammatory element. Thus, our study aims to elucidate the anti-arthritic and prophylactic activity of supplements L-carnitine (L) and zinc (Z) against MTX-mediated intestinal damage in arthritis rats. MethodsThe rats were assessed for arthritic parameters such as body weight, paw volume, x-ray scan, and serum trace elements level. To analyze the toxic effects of MTX in the rats, intestine pH, mucosal weight, digestive enzymes, myeloperoxidase, histopathological, and immunohistochemical analysis were performed. ResultsOur study demonstrated that the arthritic parameters have shown that MTX has an ameliorative effect on arthritic rats. Besides, our findings showed that low-dose MTX (2.5 mg/kg b.w.) given once a week for two weeks during arthritis treatment had toxic effects in the rat's intestine, as evidenced by changes in intestine pH and mucosal weight, decreased digestive enzymes, increased MPO, and degenerative changes in histopathological analysis. Concurrent therapy of LZ with MTX, on the other hand, restored the modifications in these parameters. ConclusionMTX in combination with LZ effectively manages arthritis than monotherapy and significantly prevents MTX-induced intestinal damage in arthritis rats. Thus, LZ could be used as an improved therapeutic and safety for MTX-instigated intestinal damage during arthritis treatments. Therefore, our combination of L-carnitine and zinc with MTX would be promising prophylactic activity for arthritis patients.
