Treatment of neutropenia in Felty's syndrome with granulocyte-macrophage colony-stimulating factor--hematological response accompanied by pulmonary complications with lethal outcome.

We report on a 67-year-old man with Felty's syndrome (FS) complicated by recurrent pneumonia and an infected wound, which was not healing in spite of maximal antibiotic and local therapy. Encouraged by previous experience, we treated him with granulocyte-macrophage colony-stimulating factor (GM-CSF). His total leukocyte count rose, but the patient's pneumonia deteriorated. In addition, a previously known chronic obstructive lung disease (COLD) was exacerbated acutely. These complications finally led to his death. Postmortem examination revealed widespread pneumonia with invasive aspergillosis and a peripheral adenocarcinoma in his left lung.

[Effect of leukocyte depleting polyester filters on thrombocytapheresis concentrates].

We studied platelet loss, leukocyte depletion, T/B cell ratio, platelet morphology and platelet function (aggregation, hypotonic shock reaction, retention and retraction) prior to and after filtration through two different polyester filters (Sepacell PL-5A, Pall PL100) as well as the posttransfusional platelet increment 1 h after transfusion in 8 pairs of single-donor platelet concentrates (Cobe Spectra, Fresenius AS 104). Leukocyte depletion was effective (>99.9%) and platelet loss acceptable in both filters, all tests showing no indication of a diminished platelet function by filtration.

[Changes in thrombocytapheresis concentrations caused by leukocyte depletion with polyester filters].

We studied platelet loss, leukocyte depletion, T/B-cell-ratio, platelet morphology and platelet function (aggregation, hypotonic shock reaction, retention and retraction) prior to and after filtration through two different polyester filters (Sepacell PL-5A, Pall PL100) as well as the posttransfusional platelet increment 1 h after transfusion in 8 pairs of single donor platelet concentrates (Cobe Spectra, Fresenius AS 104). Leukocyte depletion was effective (greater than 99.9%) and platelet loss acceptable in both filters, all tests showing no indication of a diminished platelet function by filtration.
