In 1996, I was found to have hematuria. In 2000, I started experiencing ulcers on my legs diagnosed as the result of leukocytoclastic vasculitis. I should I just go with this? In 2005, I had proteinuria. A few years later I allowed a biopsy of my kidney. Results showed a damaged kidney. Some unidentified autoimmune cause. Only treatment my nephrologist could give me is blood pressure control. Now, I am told peritoneal dialysis is next.

I am not able to establish a specific diagnosis based on the information that you present.  It is possible to have leukocytoclastic vasculitis of the kidney.  It is commonly called Henoch Shonlein vasculitis or purpura (HSP).  It can be an … Continue reading

I had protein leak in the urine for sometime. In 2017, it became more than 5gm per day. It got controlled with administration of steroids and came down to about 2gm per day. After stopping steroids, it started increasing. Biopsy interpretation is initial stage of primary membranous nephropathy. Have undergone 4 cycles of IV Cyclophosphamide and it has increased to 14gm a day. Any advise for next step is welcome.

There are a number of tests that are commonly performed on patients with Membraneous Glomerulonephritis. These tests should include an Anti-PLAR2 antibody,  Anti-THSD7A antibody, Anti-NEP antibody and others that help to determine if Membraneous disease is primary or secondary and … Continue reading

Hi I am from INDIA. Age: 60 Years My creatinine level is 1.5 mg/dl. But BUN, URIC ACID, UREA, URINE CREATININE, URINE PROTEIN, URINE ALBUMIN ARE ALL IN NORMAL RANGE. PLEASE TELL ME WHETHER 1.5 mg/dl is normal at the age 60 years. And also tell me to decrease/control the creatinine level to avoid the increase in creatinine level further.

I suggest that you visit our web site and use your serum creatinine and other vital information to calculate your estimated glomerular filtration rate (eGFR).  This will help with establishing your kidney function. You can use our calculating equation at: https://www.kidney.org/professionals/KDOQI/gfr_calculator … Continue reading

In 2016, proteinuria and neutropenia was found during routine lab work in my African American teen. Orthostatic was ruled out with multiple urine and 24 hrs test. Hem/onc work negative and ANCA and complements negative. Biopsy 3 years later states acute tubular injury. What are we missing?

Protein in the urine (proteinuria) is not usually a component of acute tubular injury.  The kidney biopsy provides the diagnosis but does not necessarily explain the protein in the urine. In some cases, further observation and time will provide clarification … Continue reading

Should I be considered that I’ve tests positive for protein ++/3 times, +/ one time, 2+ one time and a trace one time?

The tests that you report are qualitative tests that suggests you may have protein in your urine. These are generally done with a dipstick in the urine. The best test to do is a urine protein to creatinine ratio (P/C … Continue reading

Hello Doc, Our normally very healthy 12 year old, who recently had a growth spurt and is strong and tall for his age, was given a urine check which showed protein. He has no other symptoms and we have been going back and forth the past month or two to get tests and more tests. He clearly has 100 to 300 though after getting up it’s 3 and as the day goes by and he drinks water it keeps going down..as much as a trace or 30. They have not said much except to wait for the time being. Are they waiting for swelling or other symptoms? We are devastated and need some advice.Would greatly appreciate your opinion. If you need any information please let me know and I will send the blood test or give you the numbers you might need to help you get an idea of what’s going on.Thank you and God bless you.

Young and otherwise healthy young boys can develop “exercise induced” or so called “orthostatic” proteinuria (protein in the urine). This is a benign condition and he will commonly “grow out of this” by the time he hits his 20’s. It … Continue reading

I had my yearly physical 2 months ago. My RBC was 6 -below 20 as normal, protein in urine was 50 – below 20 as normal. I was dehydrated during testing. I was retested a month later. The BUN was 10, creatinine-0.8, albumin 3.9. I also had a 24 hour urine test. I didn’t eat any protein a couple of days prior to the test. Did I cause an inaccurate result because of not eating protein? Total protein was 7.2, mid normal range. Still having some foamy urine, mainly in the morning. Having some sensations in the right kidney area. Should I retest 24 hour urine and eat normal protein? My 24 hour results were below 5, unable to calculate the 24 hour UP as the random urine protein is less than the lower technical limit. Thanks for your help

Avoiding protein intake will have almost no impact on urine protein.  Eating a low protein diet without red meat might cause the serum creatinine to be a little lower than it might otherwise be and this would result in a … Continue reading

Dear Dr. I have proteinuria, chronic (immune origin) mild IgA, not aggressive yet, blood pressure medication 4 mg Atacand reduced the proteins but they are still high up to 240, normal is less than 20 ratio. Question: what is the best supplement can I take to make my kidneys live longer? I stopped smoking one year ago, and practice jogging daily. I also have ulcerative colitis since 2004. I am almost 60, male and believe in curcumine and cranberry to help my kidneys but do not know which supplements or other supplements to select. Please guide me?

I am not aware of any supplements that will further decrease the protein in your urine (proteinuria). If your blood pressure is well controlled and you are otherwise leading a healthy lifestyle, I do not think there is any other … Continue reading

I have foam in my urine, which I have read is a symptom of proteinuria, but a urine test conducted by my doctor earlier this week found no protein. Could there be another cause of my foamy urine?

Yes. Foamy urine is a normal finding if there is no excess protein in your urine.

I have read that foam in urine is a sign of proteinuria. I’m a 59-year-old male and see some foam in my urine when standing, but virtually none when sitting. Should I be concerned about the potential for proteinuria?

Foam in the urine can be normal and can also be a sign of protein in the urine. If the foam persists after flushing the toilet, then this foam is likely not normal. I have never seen any difference in … Continue reading
