Tsaritsa Yoanna – ISUL University Hospital is marking its 90th anniversary with a scientific conference on autoimmune diseases, "ISUL Days 2026", the hospital's press office said.

The conference also marks 75 years of the Department of Gastroenterology at Sofia Medical University, the first in Bulgaria and one of the first in Europe.

It opens at 10:00. The programme includes papers by specialists and cases from their practice on autoimmune diseases. Speakers include the hospital's executive director Lyubomir Penev and Prof. Boycho Landzhov, rector of Sofia Medical University, among others.

Prof. Dr Borislav Vladimirov, head of the Clinic of Gastroenterology, says the forum lets the hospital's clinics share experience and good practice on topics that cover more than one specialty.

He says it is especially useful for young specialists, who can learn things outside their own narrow field.

The Institute for Specialisation and Advanced Training of Doctors (ISUL) was founded on 8 August 1950 by decision of the Council of Ministers, on the basis of the existing Tsaritsa Yoanna workers' hospital. As well as a medical facility, the hospital became a main centre for training future health professionals.
