What a tough year it's been — and the past month sounds especially exhausting. To directly answer the question: yes, low-grade fevers can occur in lupus even when bloodwork like Anti-dsDNA and complement levels appear normal. Bloodwork doesn't always tell the full story.
Research shows that up to 60% of fevers in people with lupus are linked to disease activity, where an overactive immune system releases proteins that trigger fever — even when standard markers look fine. There are several possible reasons for a persistent low-grade fever in lupus, even with negative infection tests:
- Lupus disease activity — inflammation can cause fever even without obvious changes in bloodwork
- Vasculitis — inflammation of blood vessels, which is associated with lupus, can also cause fever
- Medication side effects — treatments like prednisone affect hormone levels and the immune system, which can sometimes contribute to fever
- Lupus nephritis — kidney involvement can sometimes present with fever alongside fatigue and flushing
It's worth noting that Benlysta and MTX can both take several weeks to months to reach full effect, so some symptoms may persist in the meantime. A MyLupusTeam member shared a very relatable experience: "Not a good day today. Fever of 100.3 with chills and so much pain." — so this kind of ongoing struggle is something others in the community truly understand.
Keep tracking the fever patterns and any other symptoms like joint pain, rash, or fatigue, and share those notes with the doctor. If the fever rises above 101°F or persists, reaching out to the healthcare team promptly is really important.
