Anemia of inflammation was my first thought.

My labs were messed up more than once but not as much as yours are. I was also HLA-B27 positive. Having recurrent uveitis which is also associated with being HLA-B27+ made the diagnosis easier. Unfortunately, a diagnosis didn't make it any less painful. Massive amounts of prednisone helped but now I'm on a biologic.

My diagnosis was reactive arthritis. The most notable autoimmune disorders that are associated with being HLA-B27+ include: ankylosing spondylitis, reactive arthritis, Behçet's disease, inflammatory bowel disease, and psoriatic arthritis.

I was diagnosed 30 years ago. I don't have disfiguring arthritis but there is extra bone and arthritis on imaging everywhere they look.

I should have considered this. My son had reactive arthritis following knee surgery at 25. We had to take him to a medical school to get the diagnosis and a round of prednisone did the trick. I’m sure the precipitating event isn’t always that obvious.
