Abstract
- Objective. Painful diabetic neuropathy (PDN) is a prevalent debilitating consequence of diabetes mellitus with lack of satisfactory therapeutic options. Methylcobalamin (MeCbl) is one of vitamin B12 analogs with known neurotrophic effects. We aimed to determine if MeCbl can relieve PDN. Materials and methods. This was a randomized (1:1) double-blind placebo-controlled trial involving PDN patients. Treatment and control group received daily 12.5 mg oral amitryptiline bid with either 500 µg of intravenous MeCbl or saline injection given on alternating days, respectively, for a 9-consecutive day period. PDN was assessed with douleur neuropathique 4 (DN4) questionnaire. Numeric pain rating scale (NPRS) was used to monitor pain intensity and treatment response. All investigators and patients were kept blinded throughout the study period. Outcomes. 42 patients, 21 on each arm had completed the study. The NPRS reduction can already be observed as early as day 2 post-intervention. Both the treatment and control group demonstrated sustained reduction of NPRS by almost one point per each time point of evaluation in the first three days (p
