Will a child suffering from purpura have kidney damage when he grows up?

Although some diseases often occur in children, their effects can easily accompany children throughout their lives if they are not treated correctly. For example, some children suffer from purpura due to their own or other reasons, and this disease may have a certain impact on the children when they grow up. Purpura nephritis is the most easily caused disease. Let's see what is going on.

Regarding purpura nephritis, the early manifestation is reflected in urine routine

The kidney is the human body's blood filtration organ and is composed of about 2 million glomeruli. A glomerulus is a small blood vessel ball. The essence of kidney damage is that 2 million small blood vessel balls have become inflamed, and red blood cells and protein leak into the primary urine. Red blood cells and protein are detected in the urine. There are different clinical reports on the incidence of purpuric nephritis. According to urine routine tests, the incidence of abnormalities is approximately 20%-60% (already very high), and some hospitals have calculated it to be about 20%. However, if all patients undergo a renal biopsy, some report that 100% of them have renal damage, but there is a distinction between mild and severe damage.

How long does it take for Henoch-Schonlein purpura to affect the kidneys?

Purpura nephritis usually lasts between 2 weeks and 2 months, but not all patients with Henoch-Schönlein purpura will develop kidney damage. The probability is not 100%. Regarding the time when kidney damage occurs, problems with urine routine tests usually do not appear immediately after the appearance of skin purpura, but usually appear between 2 weeks and 2 months. Of course, a small number may appear earlier or later. According to statistics, 90% of purpuric renal damage occurs within 2 months and 97% occurs within half a year. That is to say, the first 2 months is the dangerous period for kidney damage caused by purpura, and it is recommended to check urine routine once a week; between 2 months and half a year, check urine routine once every half a month; within 3-5 years, check urine routine once every 1-2 months. Therefore, routine urine tests should not be ignored once no problems are found. Repeated tests are required.

If purpura nephritis is diagnosed, will it manifest as gross hematuria?

The clinical manifestations of renal damage caused by Henoch-Schonlein purpura are often hematuria, proteinuria, and macroscopic hematuria is also common. There is also purpuric nephritis manifested as acute glomerulonephritis or nephrotic syndrome (accounting for about 6%-7% of purpuric nephritis). In severe cases, acute renal failure may occur. Hypertension may occur alone and is often accompanied by severe renal damage. Hypertension may occur in patients with Henoch-Schönlein purpura, and the purpuric kidney damage may be very severe (be vigilant).
