[Alveolar hemorrhage in pulmonary-renal syndrome anti-SCL/70 and anti-MPO-ANCA positive]. / Un caso di emorragia alveolare in sindrome rene-polmone anti-mieloperossidasi e anti-SCL/70 positiva.

We describe a case of pulmonary-renal syndrome on autoimmune basis, with alveolar hemorrhage and worsening renal failure. The patient was positive for anti-MPO and anti-SCL/70. Immunosuppressive therapy was effective to treat the pulmonary condition, but chronic renal failure emerged. The clinical condition did not improve after plasmapheresis, thus chronic dialysis was required.
