Since the outbreak of the pandemic, doctors have found that people who get severely ill with COVID-19 often have kidney damage along with lung damage. Why this is happening and what should doctors and patients pay attention to, “Rossiyskaya Gazeta” was told by the Honored Doctor of Russia, leading scientific editor of the distance learning service for medical workers Vrachu.ru Mikhail Kagan.
“To date, a number of studies have shown that kidney problems can occur not only during the acute phase of the disease, but also persist after patients recover from the initial infection, which can lead to severe kidney function decline throughout life. The likelihood of serious kidney damage increases significantly when a patient already has chronic kidney disease, “said Mikhail Kagan.” Research shows that nearly half of people hospitalized with COVID-19 develop so-called acute kidney injury. which occurs suddenly within a few hours or days. Because of this, uremic toxins accumulate in the blood, which is a separate danger. “
The expert named the main causes of complications: damage to kidney cells (or acute necrosis of renal tubules) caused by a lack of oxygen in the body and / or products of hyperinflammation; the formation of blood clots in microscopic vessels of the kidneys; direct damage by the virus to kidney cells.
Some people with severe kidney damage require a treatment called dialysis. This technology allows you to purify the patient’s blood in cases where his kidneys are not doing their job.
“Despite such damage in the acute period of the disease, the kidneys can fully restore their function. But in a number of people, the kidneys continue to work not as well as before. The danger here is that the development of chronic renal consequences does not cause pain and proceeds imperceptibly for Therefore, special attention to kidney function is very important when monitoring patients who have undergone COVID-19, “says Mikhail Kagan.
Preventing the progression of chronic kidney disease with the active participation of a nephrologist is an integral part of the COVID-19 treatment strategy after an acute illness. “In addition, it must be remembered that people who already have chronic kidney disease, and especially patients on dialysis treatment or living with a kidney transplant, have a significantly increased risk of severely contracting covid disease. vaccination, continue to observe all necessary precautions in order to maximally protect yourself from possible infection, “said Mikhail Kagan.
