Dr. Giuseppe De Donno, former head of Pneumology at the
Carlo Poma hospital in Mantua, died at the age of 54
(https://bit.ly/3pYYmBW): he had resigned to start his new
practice as a general practitioner, in Porto Mantovano. The
dynamics of the death remain to be clarified, on which the
carabinieri are investigating: De Donno was found dead at
home and allegedly took his own life. The investigations are
coordinated by the Public Prosecutor of Mantua, to exclude
any third party liability.
He was a well-known face of Italian medicine, and beyond.
A little over a year ago (2020) he was among the first to
experiment with the treatment of Covid-19 disease with
hyperimmune plasma, or the blood of the healed with a high
antibody rate. As reported by De Donno himself, in an initial
phase the therapy would have cured 46 people, then increased
by a few units in the following months. However, the high
interest in the therapy did not lead to the desired results.
De Donno lived in Eremo, a hamlet of Curtatone, together with
his wife Laura and their two children Martina and Edoardo. It is
here that he was found lifeless by his family. Many messages of
condolence reached the family. Among the many, it is right to
mention the mayor of Curtatone, Carlo Bottani, a long-time
friend of the doctor: “Giuseppe was an extraordinary person
– he said – I had the privilege of being by his side in the first
phase of the lockdown and I saw how spent on his patients.
History will remember him for the good he did ”.
His was a long and brilliant career: graduated in Medicine and
Surgery at the University of Modena, De Donno continued his
studies specializing in diseases of the respiratory system. His
first assignment dates back to 1992, at the Polyclinic of the
University of Modena. For about 27 years he worked at the Carlo
Poma in Mantua. In between, many in-depth studies and clinical
studies, including the one on the treatment and follow-up of
tuberculous disease. Since 5 July he was a general practitioner
in Porto Mantovano.
