[Interferon alpha 2b in pain caused by herpes zoster. Preliminary report]

We studied forty patients with Zoster Herpes, twenty two of them, with this acute disease, eighteen with postherpetic neuralgia, to those that were considered chronic. The evaluation of the effect of INF alpha 2b, in the secondary pain of Zoster Herpes acute disease, in the patients with chronic severe secondary neuralgia they shared; the evolution with the treatment for half for visual pain analog scale in both groups the patients with acute pain, entered for visual pain analog scale between 10 and two points, with medium of 8.2 SD 2.1. They did not find any significance difference with this values p < 0.6. Most of the patients with acute pain was of 6 a 0 points with the medium a 0.27 y SD: 1,2 in the chronics went from. 6 to 0 points with a medium of 1.27 (SD:2.4), with a significative difference for t Student for comparation the initial scale in final in both groups of (p < 0.0001). The comparation of the best days, the disease bettered in acute quicker than the chronics with significance difference: (p < 0.001).
