Abstract

AIMS:

Peripheral neuropathy (PN) is a common condition whose incidence is approximately 8% in elderly persons. Neuropathic pain (NeP) has a significant incidence in the general population and affects more than half of all patients with PN. The pathophysiology of PN is characterized by lesions of myelin-producing Schwann cells in peripheral nerves. Regeneration/protection of the myelin sheath after a nerve lesion is a fundamental element of repair in PN. Nucleotides such as uridine monophosphate (UMP) have proven to be efficacious in treating the cause of the myelin sheath lesion in several experimental and clinical models. Our objective was to evaluate clinical improvement in patients with PN and NeP treated with a combination of UMP+folic acid+vitamin B12 (Keltican).

PATIENTS AND METHODS:

We performed an exploratory, open-label, multicenter, study of 212 patients followed for 2 months. Pain was assessed using the painDETECT questionnaire (PDQ).

RESULTS:

The intensity of the NeP assessed at the time of the consultation progressed favorably and decreased significantly (p<0.001) in all the types of PN included. The global score for pain assessed using PDQ decreased from 17.5 points to 8.8 points at the final evaluation (p<0.001). Nonsteroidal anti-inflammatory drugs were decreased/withdrawn in 77.4% of patients.

CONCLUSIONS:

The combination of UMP+folic acid+vitamin B12 is effective against NeP associated with PN. It leads to statistically significant reductions not only in the total PDQ score but also in the intensity of pain, number of areas affected, and pain radiation. Furthermore, it makes it possible to reduce the dosage of concomitant medication.
