[Association between viral infection and pleuropericarditis: study of a case list of pleurisy and pericarditis].

The Authors report a study on a group of 47 patients affected by serositis (pleuritis, pericarditis, pleuro-pericarditis) of suspected viral origin. Two serum samples were taken from each patient at different times and were tested with many viral antigens by the complement fixation technique. The discussion is carried out on the lines followed by the majority of people in giving importance to their viral etiology and the viruses involved as agents of serositis are reported. In the present study 18 patients (38%) showed a significant rise of antibodies for viral antigens and therefore their disease might be due to viral etiology: 5 influenza viruses, 1 parainfluenza, 1 coxsackie, 1 RSV, 3 mumps virus, 5 CMV, 1 adenovirus.
