Serum Creatine

[Guest guest]

Dr Grim, (Your prior response is in red)My GP today informed me that a urine test checked last December at the local surgery and local hospital were fine. I discussed with him your response to the Endocrinologists suggestion that there may be a problem with my renal arteries. It was his opinion that in the last 15 years my serum creatine had remained 'flat' which I assume to be a good thing!He gave me a print-out with this data: Value followed by Range24 Dec. 2008 130 umol/l (60-129U)30 Sept. 2008 119 umol/l (60-129U)14 April. 2008 105 umol/l (60-129U)24 Jan. 2007 124 umol/l (66-102U)15 Dec. 2006 135 umol/l (66-102U)30 Oct. 2006 124 umol/l (66-102U)8 Mar. 2005 131 umol/l (45-120U) Sereum creatine raised slight isq though sb19 July 2004 119 umol/l ((45-120)10 Oct. 2003 126 umol/l (55-120U) agh7 Mar. 2003 122 umol/l (55-120U)31 Jan. 2003 148 umol/l (55-120U)15 Dec. 1994 130 umol/l (55-120U)I have now been recommended to another Endo. Will keep you posted. Incidentally, should I discuss reducing the Ennalapril from 10mg x2 to may be 5mg x2 (I had been on 40mg before) and I seem to be coping well on 10mg x2. After the last 20 years I would have thought that LVH is as good as it can be by now.DR Grim's previous respone:1. Spironolactone-blocking aldo will allow renin to go up to normal at least, this AII will kick the aldo up as well.2. Enalapril-increases renin and aldo by blocking ACE3. DASHing-but this may also be playing a major role in controlling your BP. Do you have the exact numbers? Was a 24 hr or even a spot urine for Na and K done at the time they were measured. I will bet you a beer it is not the renal arteries. If your average BP is less than 135/85 at home I would be very happy.Do you have a plot of your creatinines, BUN over the years. If not do one. Plot 1/plasma Cr on the y axis and time on the x axis.
