Pierre,

That explains why my neph. on the last two visits has not asked for a

urine collection.

In answer to my question " How long before dialysis " he answers 3 to 6 months.

That has happened now three times.

Has anyone any clues on that? Judging as near as I can by what you have said in

the past, I think I am at a similar stage to yourself, Pierre. I will have a

better idea when I see my neph in two weeks.

An interesting thing on blood pressure, mine has started to drop to 115/70 even

though I am still taking the same medication. This produces a slight headache

and makes me feel weak. I have reduced my Atacand (candesartan) from 16mg to

12mg and that has elevated it to 120/76 which might not appear a huge difference

but it is enough to stop the headache. I have also lost weight (6kg) which may

account for it. Has anyone else noticed a drop in BP as this disease has

progressed towards ESRD?

% kidney function

More on this subject which often comes up.

Why are so many people told they have about 50% kidney function when they

are first diagnosed with a kidney problem (IgAN or any other)?

It's a simple rule of thumb, and no calculation is involved at all. The fact

is that most people with IgAN are initially diagnosed when protein or blood

is found in their urine, and most will have slightly elevated serum

creatinine level. By the time serum creatinine is elevated, the person will

usually have lost about 50% of kidney function. Simple as that. It's usually

a guesstimate, until actual creatinine clearance can be measured.

After that, while a nephrologist will periodically order a 24 hour urine

collection for creatinine clearance and proteinuria, once the person's

initial serum creatinine is known, then most of the tracking of renal

function over the years can be done by serum creatinine alone.

I must be one of the exceptions to the rule. I was initially diagnosed at age

17. Plenty of gross hematuria and proteinuria. Serum creatinine of 1.0. It was

not until a couple years later when I came down with pneumonia that my SCr went

up to 2.1 and my neph told me I was at 50%.

If you have your serum creatinine numbers from the past year or two, what

you can do is plot them on what they call an " inverse creatinine graph " .

Then draw a line through the dots, and when the line reaches zero is approx.

when dialysis will be required. If you're interested, there are inverse

creatinine plotting tools available on some renal websites.

I don't know why your BP would be better controlled with the same dose of

medication as your kidney function gets worse, unless you've made changes in

your diet, lost a lot of weight (not sure if 6 kilos would make much

difference though). Most people's BP is very salt-sensitive at this stage,

so, if you significantly reduced your sodium intake, that might account for

it. If you take a loop diuretic, that can really help a drug like Atacand

lower your BP. There might be other factors I'm not aware of in your case,

like coming off of prednisone, for example.

I just did a 24 hour urine collection last week - the first in over a year.

I don't think I've ever done more than one or two per year, if that.

Actually, it was the same for me. They happen to have detected the blood and

protein early on, but it wasn't until I had my biopsy in '93 that I was

given the 50% number. But, my serum creatinine wasn't really elevated beyond

the normal range until then anyway. Before that, nobody thought it was as

serious as it would become many years later. At one point, they even thought

I might be one of those people who just have small amounts of protein and

blood in the urine without any real sign of kidney disease (like some

athletes).

For Ralph they found out in a routine physical that he

had blood and protein in his urine in oct of 2000. In

may 2001 they did the biopsy and said that the by the

lab work that he had 80% kidney function in the one

kidney that was functioning. His nov lab work they

tell us says he now has 40% kidney function. He gets

labwork done again on tues. We are hoping function has

not gone down even more. Can the kidney function go

back up?

Pierre,

Thanks for the info. I will plot a graph. As far as BP is concerned

I am careful with my diet and salt although my neph. has not suggested a

modified diet yet. I am not on any diuretics, just a calcium channel blocker,

Plendil (felodipine) in conjunction with Atacand. I will see what my next lot of

blood tests come up with in two weeks and I will discuss this further with you.

Since I found this web site, I am more relaxed about my condition and look to

make the best use of what I have left today in kidney function.

When I was first diagnosed, I was at 95% and it has been the same for a few

years. The only reason they know about mine is because I had the blood &

protein in my urine. I guess my case is different, but hearing you guys

talk, it does worry me that mine may go down in the next few years.

The numbers for serum creatinine can go up and down a bit, but for a chronic

condition, these are often within the margin of error of the tests, or due

to starting or stopping some blood pressure meds. In acute

glomerulonephritis, kidney function can improve once the acute inflammation

gets better, if there is no permanent damage to the glomeruli. Ralph doesn't

sound like an acute case though.

Hi Derrick.

Actually, felodipine and Atacand can be a fairly powerful combination for

lowering BP. I'm on felodipine and Avapro (which is similar to Atacand). A

lot of kidney patients take felodipine.

I'm really happy to hear a group like this can help people feel more relaxed

about their condition. Sometimes, too much knowledge can have the opposite

effect, so my goal when starting the group was to provide a forum for

sharing information about IgAN in as optimistic a setting as possible. I

think the absence of information, or worse, misinformation, can be more

troubling overall.

Marty is already there, and I'm headed towards dialysis, but don't let that

worry you. For one thing, not everyone reaches that point, and for another,

in my early days with IgAN, most of the blood pressure drugs that are now

known to be renal protective either didn't exist or weren't widely used yet.

So, those of you diagnosed from the mid-90's on have a much better chance, I

think. Also, keep in mind that it took over 2 decades for me to get to this

point. Lots of new developments can happen in that time frame.

Pierre,

Good afternoon or is it Good morning?

I have recently been diagnosed with IgA (Nov '01). I have my next meeting

with the consultant since my diagnosis on the 5th Feb '02

The only thing I know is the % I have left of my kidneys - currently @40%

with BP@144/105 on Jan 17 to a recent BP@122/86 on Jan 25 (5mg Beaters

Blockers)

What questions should I ask my Doc?

What foods can/not eat?

How much alcohol can I consume?

I would appreciate you help.

Regards

Ian, London

Hi Ian.

Just barely afternoon now, thanks.

Sorry you've had to join the club by being diagnosed with IgAN.

Here are few thing you might want to ask about.

First of all, if you want to be able to track the progression of your IgAN

over the years, you need to know what your serum creatinine is (sometimes

called plasma creatinine), and how much proteinuria you have. For

creatinine, all you need is a blood test. For proteinuria, you need to have

done a 24 hour urine collection (this will also give you your creatinine

clearance). Those are the three basic pieces of info you should know about

it.

You don't state if you have had a kidney biopsy. If not, you might want to

ask your consultant about it. If you have had one, what was the gist if the

report? For example, mine was " mesangial proliferative glomerulonephritis

with preponderance of IgA deposits and glomerulosclerosis... " . This leads

into the prognosis. Is it the rarer rapidly-progressive type of IgAN

(usually with crescents on the biopsy), or the usual chronic kind that may

or may not progress to end-stage renal disease in 10 to 30 years?

Other than that, you could ask if any dietary restrictions are necessary.

They probably aren't. You might be told to avoid table salt (this is for the

high blood pressure). You might or might not be advised to follow a lower

protein diet. It depends on your condition. So, your consultant should

advise on that. If they don't tell you to limit anything, then you can

safely assume that you don't need to at this time. There is really nothing

you can eat or not eat that affects the IgAN itself.

Alcohol is fine in moderation. A drink or two per day shouldn't be a

problem. Even people with more advanced renal failure who are on a renal

diet can have wine, for example.

You're BP is not too bad on just a beta blocker. Your diastolic is a little

on the high side though. However, the drug of first choice to use for high

BP in the case of IgAN is any one of the ACE inhibitor class. A beta blocker

might be added later if needed (unless you need one for another condition).

You could ask your doctor about that.

Hope that helps.

Sorry, forgot to add one more thing for Ian.

Ask about exercise. Vigourous exercise is usually recommended, barring any

other medical condition that might preclude it.

Thank you for a speedy response. It's a shame you're not in charge of our

train service considering the current situation (Train strike).

Yes I have had a Biopsy.....several.

One on the leg diagnosing Strep'l and obviously my Kidneys - when they

finally managed to get through!

I am 90% certain the Doc diagnosed me with chronic IgAN.

I forgot to mention the Doc put me on 2.5mg which failed to reduce my BP.

Exercise is great news. Walking is all I have managed to do....... no need

to explain where!

Doc told me to stop training because I was doing an excessive amount too

soon after being released from hospital.

I am sure you can understand. The pain isn't there all the time and when it

is, I thought it was due to playing rugby?

So I will take it gently and gradually increase my training hoping that my

BP stays low.

Keep up the good work

Rgds
