I'm a bit curious at the moment about lupus nephritis. I've been on plaquenil for my lupus for almost three years and one thing that showed in my recent tests was protein in the urine (microalbuminuria). I haven't been to see my rheumatologist for a while so I haven't been able to discuss what this means. If it's a result of taking plaquenil I imagine almost all lupies must have that problem, am I right? Or is it more likely to be the lupus causing damage to my kidneys? I am also wondering for those of you who have had kidney biopsies what made your doctors decide to do that?
