[A severe case of bronchial pneumonia due to Mycoplasma pneumoniae accompanied by immunosuppression, thrombophlebitis and hepatitis resolved with human immunoglobulins].

We present a case of severe pneumonia by Mycoplasma pneumoniae, whose clinical course was complicated by immunodepression, hepatitis and deep venous thrombosis. Treatment with pepsin-treated human immunoglobulins was unsuccessful, whereas prompt recovery was obtained by infusion of human immunoglobulins treated at pH 4.
