London, October 11 (IANS) Ethnic Asian patients have a higher risk of dying in hospital from Covid-19, while those of black ethnicity have a higher risk of requiring hospital admission for the disease, a London study warns .
The findings, published in the journal EclinicalMedicine, suggest that different treatment strategies may be required for different ethnic groups.
“For black patients, the issue may be how to prevent mild infection from progressing to severe, while for Asian patients it may be how to treat life-threatening complications,” said one of the study’s authors, Ajay Shah, professor. of Cardiology at King’s College London and Consultant Cardiologist at King’s College Hospital.
The study examined the relationship between ethnicity and SARS-CoV-2, the virus responsible for Covid-19.
The results confirm that ethnic minority patients bear a greater burden of the disease than white patients and also find that black and Asian patients are affected at different stages of the disease.
“The evidence is now clear that black people and ethnic minority groups are most severely affected by Covid-19,” said Professor Chris Whitty, England’s chief medical officer and director of the National Institute for Health Research ( NIHR), Britain’s largest funder. of research in health and care.
The study analyzed data from 1,827 adult patients admitted to King’s College Hospital, southeast London, with a primary diagnosis of Covid-19 between March 1 and June 2, 2020.
Researchers analyzed mortality in this group and also compared a subset of 872 patients admitted from South East London with 3,488 matched controls residing in the same region to determine how ethnicity is associated with the need for hospitalization for a serious illness. .
Of these 872 admitted patients, 48.1% were black, 33.7% white, 12.6% mixed-race, and 5.6% were of Asian ethnicity.
The analysis showed that black and mixed ethnicity patients have a three times higher risk of requiring hospital admission once infected with Covid-19 compared to white inner-city residents of the same region.
This is only partly explained by comorbidities and deprivation, as when adjusting for these factors, black patients still have a 2.2 to 2.7 times higher risk of admission.
However, the hospital survival of these patients was not significantly different from that of white patients.
In contrast, Asian patients were not at higher risk of requiring hospital admission with Covid-19 than white patients, but their in-hospital death rate and need for intensive care unit admission was higher than in the other groups.
The researchers found that ethnic minority patients were 10 to 15 years younger than white patients and had a higher prevalence of comorbidities, especially diabetes.
The study suggests that while comorbidities and socioeconomic factors contribute to the impact of Covid-19 in minority communities, there may be an important role for other factors, such as biological factors, that affect different subgroups in different ways.
The results of this study are likely to be applicable across London and similar cities in the UK, but more research is needed to translate it to multi-ethnic populations in other countries.
The number of confirmed Covid-19 cases in Britain surpassed 5,90,800, while the total number of deaths reached 42,760 on Saturday.
