Hi SerumNegative,
I do not have experience with orencia or rituxan, but i do have RA and sjogren's. From what I understand TNF is implicated in sjogren's, just as it is in RA, so any of the tnf-inhibitors would work. I currently take enbrel and mtx. One thing I noticed in your signature is that you're taking only 5 mg of mtx/week. This is a fairly low dose. I started these drugs taking enbrel alone and gradually adding mtx. Mtx didn't start making a difference until my dosage was increased to 15 mg/week. That in combination with the enbrel has been my magic elixir. Is there a reason why your doctor has not raised your mtx? For reasons no one seems to understand, it often take both mtx and one of the tnf-inhibitors to control these stupid diseases.
