Could it be lupus nephritis?
Hello guys. My dad 65M was diagnosed with spilling protien in his urine and hematuria with some really small kidney stones on a routine investigation. He has no hypertension or blood pressure or no family hx of any kidney or auto immune disease. All her blood works were fine with a normal kidney function and serum electrolytes except for low platelets (85 and then 94k)
He was started on losarton and prednisone 10 mg considering it could be just some temporary issue. After a month when we tested him again for 24hour urine he was nearly still spillign the same amount of protien(1gram)
He was given a panel of tests which showed normal C3,TSH as well as negative AMA , Asma but his ANA titre showed 1:80 nuclear speculated. We are still awaiting the Anti ds DNA test and will be visiting his primary nephrologist once the test is backbut I am quite worried as could it be isolated lupus nephritis? He has absolutely no other symptoms of lupus which kind of makes me a bit optimistic if him jot having lupus but due to the 1:80 titre and possiblility of isolated LN i am quite concerned.
Any one gone through same and has any advice?
