Hi all!
I'll try to keep this brief. I'm just wondering if anyone else had a similar course and if so what your diagnosis was in the end!
Abnormal testing so far:
—ANA positive, 1:320 titer, DFS/AC-2 pattern
—C4 hangs low between 15 and 19 (19 was below the reference range in one assay, but the 15s were in a different assay where 15 is the lowest end of normal)
—TSH in the 4s and 5s with occasionally mildly elevated anti-TPO (14) or anti-Tg (3) antibodies, but levothyroxine did not help with symptoms
—Elevated kappa free light chains (barely) with a normal kappa-lambda ratio
—WBC count slowly declining but normal, bounces between 4.1 and 4.3 lately
—EMG/NC showed minor R ulnar neuropathy
Everything else has been normal (including lupus-specific antibodies like dsDNA, Sm, RNP, histone, Ro, La).
Symptoms in the order they happened over the past two years: GERD, chronic migraine (controlled with Botox), fatigue, joint aches in DIPs and MCPs (and sometimes PIPs), rash across face (doesn't always spare the nasolabial folds but darker patches now do during fevers), daily low-grade fevers (99s, usually, occasionally above 100 in the evenings), little rash splotches on sun-exposed areas on the chest.
The medical team is split. One rheumatologist (second opinion) is certain that this is mostly psychosomatic, that a DFS/AC-2 pattern means that this is not autoimmune, that temperatures in those ranges don't count as fevers, that the rash is rosacea, and that the joint pain is from hypermobility and deconditioning. Another wants to follow me every few months and retest because she thinks that this could absolutely be early autoimmune disease and that it often takes time to tell. Infectious disease is taking the fevers seriously and doing a full fever of unknown origin workup but guesses autoimmune disease or a hidden infection. Hematology, neurology, and family medicine think that this is likely autoimmune.
I guess I'm wondering if anyone else has had a similar set of symptoms or lab results, what your ultimate diagnosis ended up being, and if the specific antibody results ever turn positive later in the disease. (Fortunately dermatology just biopsied the facial and chest rashes for both hematoxylin and eosin staining and direct immunofluorescence at my primary rheumatologist's request, so I might have some definitive answers soon!)
Finally, I really appreciate this community! Your posts have been so helpful! I'm happy to post about my course if this does end up lupus.
