Newbies who have just suffered from kidney disease, and people who are not very concerned about the frontier fields of kidney disease, often misunderstand or misunderstand the test indicators related to kidney disease. As a result, misconceptions such as “lowering creatinine”, “eliminating occult blood” and “urinary protein first” appear.
If there is a misunderstanding of the indicators, it may lead to abandoning the basics, seeking medical treatment and asking for medicines astray.
So, what are the key indicators of chronic kidney disease? There are mainly 3.
I. The most important indicator of chronic kidney disease: blood pressure
Many kidney disease patients only look at urine every time they check protein. Indeed, urinary protein is the most typical and common abnormal indicator of nephropathy.
However, the most important indicator of kidney disease is not urine protein, but blood pressure!
The important thing said three times, blood pressure, blood pressure, blood pressure!
Recently, there is another epidemiological study of kidney disease. The top medical journal “The Lancet” published an article that: In East Asia including China, as well as Eastern Europe, tropical Latin America and Western The most damaging factor for people with chronic kidney disease in sub-Saharan African countries is high blood pressure.
60% of patients with kidney disease have hypertension. Patients with hypertension tend to have more severe pathology, generally have poor drug response, and have a greater risk of disease progression.
The progression of kidney damage caused by hypertension is much faster than that of proteinuria. Not only can high blood pressure make kidney disease progressive like proteinuria, it can also cause acute kidney failure in a short period of time, and it can cause cardiovascular disease, the largest cause of death in uremia.
It can be said that hypertension directly controls the final outcome of patients with kidney disease.
The most important symptom for kidney patients is high blood pressure. But every time I popularize low-salt diets and emphasize the importance of blood pressure, I can see from the sudden drop in reading and forwarding data, and few people pay attention. what can I do? From now on, don’t tell everyone about the pressure reduction? I have to say it again and again every three to five.
In fact, not only our kidney disease patients, but the vast majority of people, including the 300 million hypertensive patients in our country, do not fully understand the harm of hypertension.
Second, the most common indicator of renal failure: urinary protein
The importance of urinary protein, friends with kidney disease all relatively clear. Here’s a reminder:
Do not pay attention to the qualitative urine protein (the plus sign “+” in the urine routine), nor the concentration of urine protein (the unit after the test result). It is mg/L or g/L or the like, which is divided by volume, which is the concentration unit), and the 24-hour urine protein quantification and urine protein components should be valued.
24-hour urine protein quantification is the most accurate indicator to measure the amount of protein in urine, The score is the most precise test item for analyzing the various components of urine protein. Based on these two tests, a more reliable treatment plan can be formulated.
3. The most accurate indicator for evaluating renal function: glomerular filtration rate
not serum creatinine.
Although creatinine still firmly controls the leader of the renal function test list, it has exposed many defects:
< p>The abnormal time is late, which may delay the treatment time; the basic creatinine value of each person is different, and the standard cannot be unified; it is easy to be disturbed and fluctuates; it is impossible to judge the severity of uremia, etc.
Therefore, simply using creatinine to evaluate renal function is often inaccurate. The most accurate indicator for evaluating renal function is glomerular filtration rate.
Also, creatinine is a small molecule with very little toxicity, which itself has no effect on renal function. What harm, there are many patients with creatinine as high as 2000μmol/L or 3000μmol/L who do not feel physical discomfort. The most toxic substances are quack and indole.
So “creatinine reduction” itself is a false proposition. First, because the inherent cells of the kidney are not regenerated, there is no real creatinine lowering method in the world; second, because even if you Forcibly reducing the creatinine, it is only a single test value that looks good, but cannot restore renal function.
If you have to lower your creatinine, that’s easy too. Aixite, Niaoduqing, calcium dobesilate, vegetarian food, etc., and even sex reassignment surgery, there are 100 ways to Lowering creatinine, but is it useful to lower it? The kidneys still do not function, the complications that should come will still come, and eventually they still need to beTo dialysis to maintain life.
Chronic renal failure is about protecting kidney function (glomerular filtration rate), not lowering creatinine.
