Increased serum CNTF level in patients with amyotrophic lateral sclerosis.
The role of ciliary neurotrophic factor (CNTF) in the etiopathogenesis of amyotrophic lateral sclerosis (ALS) is still not clear. The aim of this study was to measure serum CNTF level in patients with ALS. The study involved 36 ALS patients and 43 control group subjects. CNTF was measured by the enzyme-linked immunosorbent assay. Results showed that the serum CNTF level in whole group of ALS patients was significantly higher from those in the total control group subjects. CNTF level was not dependent on the clinical state of the ALS patients, type of ALS onset, or duration of the disease. Results indicate that CNTF may be a reactive component resulting from the disease, but it cannot be a marker of ALS activity. It is possible that the increase in serum CNTF level is the result of the muscle denervation seen in this disease.
