Can lupus causes protein in the urine or UTI or SLE?
Patient: Hello. My daughter has SLE/mixed connective tissue disorder. Several times over the last 2 years she has had urinalysis with 1+ protein. She has had several normal urinalysis in between her abnormal ones. Her most recent one shows 1+ protein, trace ketones, no glucose, trace blood and trace leukocyte esterase. Due to her lupus, she also has pulmonary fibrosis which she took 9 monthly cytoxin infusions for and fatty liver disease (non autoimmute) Could her occasionally throwing protein in her urine and ketones be the starting of the SLE attacking her kidneys? Or could it just be a UTI? Doctor: it could be a UTI, but the only way to confirm it is with a urine culture and sensitivity.however if the proteinuria continues she will need to get it checked for lupus.also you need to know the exact amount of protein she is losing by getting a urine protein creatinine ratio done.
