Thymomodulin is an immunomodulating agent which is derived from calf thymus by partial acid lysis. It promotes T-cell maturation, enhances antibody synthesis and improves the phagocytic response of neutrophils. Clinical trials have revealed the effectiveness of this thymic derivative in the prevention of recurrent respiratory infections (RRI) in children and in adults; 11 patients (8 males and 3 females; age range 18-76 years) with chronic bronchitis dominated by recurrent respiratory infections were studied. They were treated orally for 6 months during the winter season with 120 mg/day of thymomodulin. All the subjects were asked to keep a diary recording the intensity of their symptoms, the number of working days lost (days of illness) and the use of antibiotic and/or mucolytic drugs. At the beginning and at the end of the trial each patient was subjected to a control with a flexible fibreoptic bronchoscope with bronchoalveolar lavage to evaluate the phagocytic response of alveolar macrophages. At the end of therapy a significant improvement of the clinical status, evaluated by the above-mentioned parameters, of the bronchial mucosa aspect and an increase in alveolar macrophage superoxide production was noticed (from 0.1 +/- 0.09 and 0.8 +/- 0.5 nmol to 1.6 +/- 0.8 and 4.1 +/- 2.2 nmol with PMA or zymosan particles respectively; p less than 0.001). During thymomodulin treatment no side-effects were recorded.

UI MeSH Term Description Entries
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.
