Your report is showing consistent elevation of SGPT and a continuous use of METHOTREXATE
seems to be the cause for it.
METHOTREXATE is known to be a hepatotoxic drugs and it not only cause elevation of liver enzymes but can also cause chronic fibrosis
this is definitely a matter of concern and guidelines suggest that if significant hepatic enzymes abnormalities persist for more than 3 months,then liver biopsy
should be performed.
You must discuss with your doctor about it.
