centromere pattern is most often associated with CREST (Calcinosis; Raynaud's; Esophageal dysmotility; Sclerodactyly; Telangectasias)
The speckled pattern is found in SLE and other connective tissue diseases.
I have read both that the pattern can change and that you can have 2 patterns at once (although 2 at once confuses me!).
It is also important to remember that an ANA does NOT define the disease! It may suggest a disease to look for, and *if* other symptoms of that disease are found then, and only then, would it be diagnosed.
A positive ANA alone may not mean anything! Strange, huh? More on ANA is found in our thread Lupus Resources (link below).
Try not to worry too much, worry/stress can make these diseases more symptomatic, and not worrying can certainly not hurt you. Just carry on following up...
