Pope Francis remains in critical condition, although he hasn't had further respiratory crises since Saturday evening, the Vatican Press Office said on Sunday evening.
Blood tests showed that his thrombocytopenia, which occurs when the platelet count in the blood is too low, is stable but revealed early, mild signs of kidney failure, which is currently under control, according to the medical bulletin.
The pontiff is continuing to receive high-flow oxygen therapy, the Vatican Press Office said.
The pope is alert and well-oriented and the prognosis remains reserved, it added.
The Vatican also said that on Sunday morning the pope participated in a mass together with those taking care of him in a special area on the tenth floor of Rome's Agostino Gemelli Hospital.
The pope was admitted to Rome's Gemelli Hospital on 14 February after experiencing breathing difficulties and was initially treated for bronchitis before being diagnosed with pneumonia in both lungs. On Saturday evening, the Vatican issued a bulletin saying the pope had suffered a respiratory crisis and that he was in critical condition.
