Sorry, I got distracted. Never got around to the third and final installment in the Most Common Rheumatology Chief Complaints series. But better late than never.
1) +ANA
As a preface, ANA is an autoantibody. People order it and then don't know what to do with the results. That's where I come in.
Me: In one sentence, what brings you to a rheumatology office today?
Patient: My lupus test is positive, so my doctor sent me to see you.
Me: You mean the ANA?
Patient: Yeah, my lupus test.
Me: Well, the ANA isn't exactly a test for lupus. But we'll talk about that. What symptoms did you have that made your doctor want to run those tests?
Patient:
[The following are selected examples.]
1) I tried a new moisturizer, and my face broke out in a rash. My doctor was afraid it could be lupus.
2) My low back's been hurting for the last several years, ever since my car wreck. I just can't take it anymore. My doctor thought maybe the reason the pain wasn't going away was lupus.
3) I sneezed like 14 times in a row the other day. My doctor thought it might be lupus.
4) I'm just tired all the time. My doctor thought it might be lupus.
5) I get urinary infections all the time. My doctor thought it might be lupus.
Me: Sigh. OK. Let me ask you some other questions. [Big breath] Do you have rashes on the skin, hair falling out, sores in your mouth, sores in the eyes, super dry eyes so you can't wear contacts, super dry mouth so you can't swallow down crackers, fevers or infections, trouble breathing, pains in the chest, palpitations, cough, coughing up blood, coughing up sputum, belly pain, nausea, vomiting, diarrhea, constipation, blood in your stools, dark dark black stools, burning when you pee, blood in the pee, super foamy pee like a head of beer in the toilet, joint pains, swollen joints, red joints, muscle aches, ever had a blood clot in your legs or lungs, trouble bleeding like you cut yourself shaving and it just won't stop, numbness or tingles anywhere?
Patient: Well, sometimes I get constipated if I don't take my fiber.
Me: Great news. You don't have lupus.
Patient: But my lupus test was positive.
Me: You see, the ANA isn't exactly a test for lupus. It's a generic screening test, so just because it's positive doesn't mean you have lupus. There's lots of perfectly normal, healthy people with positive ANAs.
Patient: But if I don't have lupus, why do I
[insert previous examples here].
Me: Maybe you just had
1) an allergic reaction
2) mechanical back pain
3) a bad day
4) sleep apnea
5) plain old urinary tract infections.
But the good news is, you don't have lupus.
Thank you for this interesting consultation. The patient has been seen and discussed with Dr. A, who agrees with the above assessment and plan.
Sincerely,
