['Polyvalent IgM-enriched intravenous human immunoglobulin (IVIG) preparations are discussed to be beneficial regarding sepsis outcome.', 'Sixty-four patients with abdominal infection were treated with Pentaglobin or Albumin. Serum levels of endotoxin and chemokines were determined.', 'Incidence of fever was 19/28 in the pentaglobin and 18/26 in the albumin group, the percentage of days with fever was 34 +/- 26 for pentaglobin and 43 +/- 25 for albumin (mean +/-SD). Procalcitonin levels of the pentaglobin treated patients fell under the upper limit of normal on day six whereas levels of albumin patients remained elevated.'] Does igM-enriched immunoglobulin ( pentaglobin ) positively influence the course of post-surgical intra-abdominal infections?
