A new study in the US showed that Hispanics live longer on dialysis than white people.
This recently the scientists reported in the authoritative journal of the American Society of Nephrology (ASN) "Clinical Journal of the American Society of Nephrology".
Recall that dialysis is a method of removing toxic products and excess fluid from the blood. Normally, these kidneys successfully cope with these problems, but with severe kidney diseases the patients' life depends on the dialysis procedure.
Dialysis can also be useful for rapid cleansing of the body from certain poisons and medications.
Every day, through the kidneys of a healthy person, about 1,500 liters of blood are filtered, which makes it possible to effectively remove toxins and excess of various substances from it. If the kidneys are not able to filter these substances, the patient develops swelling, accumulation of toxins in the blood, in severe cases this can lead to coma and death.
American scientists have long studied the difference in the effectiveness and safety of various therapies in representatives of different ethnic groups. This time, researchers collected data on 1.3 million adult patients who underwent dialysis between 1995 and 2009. The information was taken from the RDS database (Renal Data System). And here scientists expected a surprise: it turned out that the white patients on dialysis lived less than Hispanics. And that is not all.
Latin Americans and African Americans have long lived on dialysis compared to whites, especially those from the Caucasus. This trend persisted in all age groups, except for the youngest patients aged 18 to 29 years. In this group, black patients on dialysis had a higher chance of dying than white.
The reasons for this difference in outcomes are still in question. According to national statistics, Latin Americans have the worst level of health insurance, and this group has no medical advantages over the white population of the United States.
Previous research suggests a "paradox of survival" of dark-skinned patients on dialysis. With a worse survival rate for black patients in the general population, they have better rates in dialysis.
The researchers put forward an interesting assumption. In their opinion, Latin Americans and black patients have a greater risk of dying before the onset of kidney failure, so people who have lived up to it can be stronger and healthy, which causes better indicators already on dialysis.
The results of the study may be limited to an inaccurate indication of the race, but these data are almost impossible to fully verify due to the huge number of participants.
The authors summarized that the best survival rate on dialysis in Latinos, the average in African Americans, and poor in white patients, with the worst indicators for Caucasians.
Dr. Guofen Yen of the University of Virginia at Charlottesville, the author of this study, says it is very important to continue to investigate medical differences between ethnic groups, because this will help predict the outcome of a particular treatment in a particular patient, making more informed decisions.
