Covid-19: Study reveals diabetic patients with eye disease at a five-fold risk of severe coronavirus


People with diabetes and eye disease have a five-fold elevated risk of requiring intubation when hospitalised with Covid-19, counsel the findings of a new research.

The research, revealed at the moment in Diabetes Research and Clinical Practice by King’s College London, recognized for the primary time the risk related with diabetic retinopathy and Covid-19.

Diabetic eye disease is a widespread complication of diabetes and is attributable to harm to the small blood vessels within the eye. In 2014, the prevalence of diabetic retinopathy was 54.6% in individuals with Type 1 diabetes and 30.zero per cent in individuals with Type 2 diabetes.

The research investigated 187 individuals with diabetes (179 with sort 2 diabetes and eight with sort 1 diabetes) hospitalised with Covid-19 at Guy’s and St Thomas’ NHS Foundation Trust between 12th of March and seventh of April 2020.

Diabetic retinopathy was reported in 67 (36%) of patients, the bulk with background retinopathy. Of the 187 patients hospitalised with severe Covid-19, 26% had been intubated and 45% of these patients had retinopathy. Retinopathy was related with a five-fold elevated risk for intubation. In the cohort, 32% of patients died and no affiliation was noticed between retinopathy and mortality.

First writer of the research, Dr. Antonella Corcillo from the School of Cardiovascular Medicine and Sciences at King’s College London stated: “This is the first time that retinopathy has been linked to severe Covid-19 in people with diabetes. Retinopathy is a marker of damage to the blood vessels and our results suggest that such pre-existing damage to blood vessels may result in a more severe Covid-19 infection requiring intensive care treatment.

Senior author, Dr Janaka Karalliedde from King’s College London, said: “There is increasing evidence that there is significant damage to the blood vessels in the lung and other organs in patients hospitalised with severe Covid-19. People with diabetes are at high risk of vascular complications affecting the large and small blood vessels.

“We hypothesise that the presence of diabetes-related vascular disease such as retinopathy may result in greater vulnerability and susceptibility to respiratory failure in severe Covid-19. Therefore looking for the presence or history of retinopathy or other vascular complications of diabetes may help health care professionals identify patients at high risk of severe Covid-19. Further studies are required to investigate the possible mechanisms that explain the links between markers and manifestations of diabetic vascular disease such as retinopathy and severe Covid-19.”

RNIB Specialist Lead for Eye Health, Dr. Louise Gow stated: “RNIB hope this research will result in greater awareness of those who are most at risk of serious complications from Covid-19. With vaccine planning underway, consideration must be given to prioritising people with diabetic retinopathy. It also highlights that it is vital that information about Covid-19 is available in formats that are accessible to people with sight loss so that they know how to protect themselves.”

Limitations of this research embrace its comparatively small pattern measurement and that, as it’s a cross-sectional research, it’s unable to establish a causal relationship between retinopathy and severe Covid-19 outcomes.
