To this day, hemophilia is considered incurable.. There are no specific clotting factors in the blood of patients with hemophilia. As a result, patients with hemophilia are exposed to constant danger associated with external and internal bleeding.. Patients will have to inject several times a week to form artificial blood clotting..

American specialists at University College London have achieved the first results on the problem of hemophilia B. They used a safe for health adenovirus 8, combined it with the gene responsible for the production of factor IX of blood clotting in the liver, and administered a series of injections with the virus to patients..

How did the experiment go

The study group included six people who received the modified virus at various doses..

If the normal level of factor IX in the blood of a person suffering from hemophilia is one percent, then after the injection this figure should increase from 2 to 12%, depending on the dose..

This level of blood clotting is maintained for three months from the date of receipt of the modified virus by the patient.. The patients who took part in the experiment no longer needed regular injections.. As 26-year-old Carl Walker put it, his physical activity before the new invention was significantly limited due to the existing risk of bleeding.; after the injection, you can not worry about avoiding injuries and bleeding - there is no longer such a need.

Hemophilia patients: lifestyle According to experts, this study can be classified as a historical event in the development of medicine, as scientists for the first time managed to achieve a lasting effect on the production of the desired blood factor in the liver - in a therapeutic way.

Scientists are working in the field of additional research on the effectiveness of the new method, monitoring the condition of patients in order to determine the exact range of the virus, to identify all kinds of side effects..
