UCTD is a different diagnosis and is an overlapping connective tissue disease which means you have lupus and symptoms of one or more other AI diseases. UCTD is often used when a case is not able to be diagnosed precisely and often morphs into something more concrete like MCTD (mixed connective tissue disease) which is lupus, scleroderma and polymyositis.
Treatment is often the same as for lupus. Alternative medicine, diet and lifestyle might help to complement more aggressive treatment but don't think of them as primary treatments for serious AI disease...they are not.

Suggest you get a second opinion to make sure you are being treated properly. Plaquinel is usually given for mild cases and stronger meds are available to deal with severe or complicated cases.
