question: my 14 year old daughter was diagnosed with henoch schonlein purpura 1 1/2 years ago.  she is now on methatrexate injections weekly.  we were called with a report that her liver enzymes were elevated this time.  we knew that sed rate levels and kidney ketones were the major things to look for, but we're unsure what elevated liver enzymes do.  Can you answer that question?
