Introduction:

Chronic inflammatory demyelinating polyneuropathy (CIDP) is an autoimmune demyelinating disease. Conventional treatment is based on immunomodulation and immunosuppression. The use of stem cells is a novel therapy in autoimmune disorders, so it is included as therapy.

Objective:

To determine the efficacy of mobilization of stem cells by applying granulocyte colony-stimulating factor (G-CSF) in patients with CIDP who have followed other lines of treatment.

Material and Methods:

A randomized, double-blind study was carried out on a cohort of 45 patients with CIDP. G-CSF was administered to 25 patients and 20 of them continued with the usual treatment. These patients were previously treated with other therapeutic variants for more than three years without satisfactory response.

Results:

There was a prevalence of men (64.4 %), Diabetes Mellitus had a greater association, and the most used medications were steroids. Clinical symptoms and signs improved significantly after treatment. TCSS scores significantly decreased at one and three months after treatment, but this decrease was not maintained at the end of the study. The conduction velocity and action potential of sensory and motor nerves improved considerably after treatment.

Conclusions:

The effectiveness of the use of G-CSF shows an improvement of clinical symptoms. The results of neurophysiological studies have a better course than other therapeutic variants during the first months, with good safety and tolerability, so it can be included in the conventional therapy for the CIDP.
