Have you been diagnosed with drug-induced lupus, and what tests were involved?

Yes, many people have been diagnosed with drug-induced lupus (DIL). Your situation with increasing antihistone antibodies is particularly relevant, as these are commonly associated with DIL.

Common tests for diagnosing drug-induced lupus include:

* ANA test (which you've had positive results for years)
* Anti-histone antibody test (yours is positive and increasing - 2.3)
* Anti-dsDNA test (yours is negative, which is typical for DIL)
* Complete blood count to check for cytopenia
* Coombs test for antibodies attacking red blood cells
* Urine tests to evaluate kidney and liver function
* Sometimes skin biopsy to rule out other conditions

Your pattern of positive ANA, increasing antihistone antibodies, and negative dsDNA is actually quite consistent with drug-induced lupus rather than systemic lupus.

About your medications:

Beta-blockers aren't typically listed among the most common drugs causing lupus. The most common culprits include hydralazine (for high blood pressure), procainamide (for irregular heartbeat), and certain antibiotics.

However, diagnosing DIL can be tricky because symptoms might start weeks or months after beginning a medication, and you've been on your beta-blocker for 20 years. Your doctor needs to consider your complete medication history.

A MyLupusTeam member shared: "It seems drug-induced lupus may be underreported because not all doctors test for it."

Your EBV history is also worth noting, as viral infections can be associated with lupus development.

Have you discussed your increasing antihistone antibodies with your rheumatologist? This trend, combined with your medication history, warrants a thorough review.
