This is for my husband, 58 years old. Last year, June, his serum creatinine was 1.23 and GFR WAS 65. This week tested it was 1.4 and GFR 55. He has high blood pressure. Fasting sugar 111. Prostate enlargement. Yesterday, consulted a doctor and suggested calcitriol 0.25, temulose and minnamineforte. Let me know is it safe taking calcitriol or not. I fear it may cause any adverse condition.

Calcitriol is an active form of vitamin D and is commonly used in the treatment of bone disease and secondary hyperparathyroidism in patients with chronic kidney disease (CKD). I am unable to recommend specific medical treatment without performing a complete … Continue reading

I am a 76-year-old white male. A year ago I had an eGFR of 45 mL/min/1.73m2 and a P/C ratio of 9,600 mg/g. After taking Valsartan 80 mg once a day since then, my current eGFR is 46 and P/C ratio is 1,080 which is a radical drop in my P/C ratio. All other things being equal, is my prognosis the same as another person who has a P/C ratio of 1,080 without taking Valsartan 80 mg once a day?

I don’t know any way to answer your question because there has been no study comparing people with and without an angiotensin receptor blocker (ARB) agent such as Valsartan who have had a response to Valsartan in the first place. … Continue reading

I am 65 years old male with stage 3a CKD. All of my blood and urine work is in normal ranges but my eGFR is 50-53 and creatinine is 126. I have blood pressure well controlled with Losartan and Norvasc 110-115/ 75. I follow a DASH type diet. A nephrologist consult, which I asked my PCP for, said my numbers are all normal and did not recommend any dietary modifications other than healthy eating habits and that I could do some research on a lower protein diet if I wanted to. I am fearful of developing MBD. My serum phosphorus is 1.4 mmol/l, the lab range is .8-1.5. My calcium is 2.34 mmol/l, the lab range is 2.1-2.6. My PTH intact is 6.5 pmol/l, the lab range is <7. The consult review letter from the nephrologist to my doctor said I was extremely healthy. I find this comment puzzling given that my eGFR is less than 60. She also had me do a 24 hour creatinine clearance which showed a calculated GFR of 67. I don’t know who or what to believe anymore I am so confused. Should I be following a low protein, low phosphorus diet? Am I in danger of progressing to MBD? I am very scared.

The situation that you describe is very early Stage 3a chronic kidney disease (CKD).  If no other causes were found with your nephrology consultation, it is likely that you have CKD related to your high blood pressure and with your … Continue reading

I have a GFR of 45 but I am confused. One chart says I’m 3b like the doctor. But another says 3a. I don’t get it.

Stage 3 chronic kidney disease is present when your estimated glomerular filtration rate (eGFR) is between 30 and 59 milliliters per minute per 1.73 meters squared and has been so for at least three months.  Stage 3 is split in … Continue reading

Recently I went into Stage 4 of kidney disease.  My GFR is 17 and creatinine was 3.66.   I do have high blood pressure but is pretty good with meds (140/80)…also diabetic with an avg reading of 139.  I really am watching my sodium intake and potassium (levels were good with last blood tests).  Old remedy I am told is vinegar with the mother (1 tsp per day with glass of water).  What are you thoughts or experience with this old remedy?   I do drink a lot of water to keep hydrated and flush the kidneys.

I have had many patients mention this to me.  I have never seen any study that suggest that vinegar is of benefit in patients with chronic kidney disease (CKD).  I have not observed any ill effects and I have not … Continue reading

My son is active on the Transplant list due to a genetic kidney disease and is also a competitive college athlete. His coaches have said that because he is “not in shape” he cannot play. Often he has trouble keeping up in the conditioning program because he is fatigued easily. His GFR is 20 creatinine is 3.9 Is his kidney condition what is really holding him back or is he out of shape?

There have been several professional athletes that have had advanced kidney disease and still able to play professional sports.  Hence, kidney disease does not preclude physical conditioning but the anemia and the fatigue do make the conditioning more difficult.  I … Continue reading

I am a 31 year old female with PCKD. My question is how soon can I be put on the transplant list? I have frequent recurring UTIs and kidney stones. My kidney function is still in the 90’s.

Polycystic kidney disease (PCKD) is a slowly progressive disease.  You should not require kidney transplantation until your estimated glomerular filtration rate (eGFR) is less than 20 milliliters per minute per 1.73 meters squared.  The eGFR would need to be less … Continue reading

Doctor glad to greet you, My question is that I have creatinine at 2.70 and glomerular filtration at 20%. Are these values of chronic kidney disease very alarming? To start with the transplant? I don’t have diabetes or high blood pressure, my sodium tests partial urine glucose are fine. Under the creatinine 2 points and glomerular filtration rose 1 point I do not know how I can know what happened to my kidneys I can not biopsy because my kidneys are small, Doctor you can say about it? Thank you

Your estimated glomerular filtration rate (eGFR) is 20 and this would be consistent with Stage 4 chronic kidney disease (CKD).  When your eGFR is less than 20 milliliters per minute per 1.73 meters squared, you could be eligible to apply … Continue reading

I am a healthy 35-year-old woman with normal blood pressure, not obese, 5’10”, active, not an amputee, not a bodybuilder and I don’t take protein supplements. Ten months ago during routine bloodwork, they found my GFR to be 68. A nephrologist had me do a 24 urine catch, and I don’t know the numbers, but they said my kidneys were functioning in a normal range. He chalked up the low GFR to me being tall. Two weeks ago during routine bloodwork it was down to 53. My creatinine is at 1.2. I called the nephrologist’s office and the nurse pretty much blew it off. It seems like a big drop and a low number for someone my age anyway. Should I be concerned?

I am unable to make a specific diagnosis based on the information that you present.  A drop in the estimated glomerular filtration rate (eGFR) from 68 milliliters per minute per 1.73 meters squared to 53 would be a significant drop. … Continue reading

I have had several blood tests dating back to March of 2017. The tests all show creatinine levels of 1.3 to 1.6 and eGFR of 44 to 55. My family doctor says I don’t need to do anything unless eGFR drops below 30, but my research indicates I should be doing something now. Also, I am on hydrochlorothiazide for high blood pressure and I am wondering if kidney disease could be causing high blood pressure?

High blood pressure and kidney disease are similar to the conundrum of chicken and the egg.  High blood pressure can cause chronic kidney disease (CKD) and CKD can also cause high blood pressure. Hence, the goal of treating high blood … Continue reading
