Introduction: Low back pain is one of the main complaints registered by general practitioners, reaching about two-thirds of all adults, at some point in their life. It frequently causes a diminished quality of life on the patients, and often results in the prescription of both non-steroid anti-inflammatory drugs and additional diagnostic exams. This has created a demand for safer treatments with fewer side effects. It is well known that low back pain is a clinical manifestation of vitamin D deficiency. In this context, supplementation with vitamin D appears as a promising therapeutic, being supported by several studies that have found an association between low back pain and deficiency in vitamin D in the adult population.
Objective: Determine whether there is evidence to support the claim that vitamin D supplementation improves the pain symptoms in adult patients with low back pain.
Materials and Methods: We have searched for recent papers on this subject in the following databases: National Guideline Clearinghouse, Tripdatabase, Cochrane, PubMed and Index of Portuguese Medical Journals. We selected the papers published in the last decade, written in English, Portuguese or Spanish, and indexed with MeSH the terms “vitamin D” and “low back pain”. We included papers where the outcome was an improvement in the pain symptoms in adult patients with low back pain. These papers were classified based on the Strength-of- Recommendation Taxonomy (SORT).
Results: After applying the inclusion and exclusion criteria, we have found 18 papers and selected among them 2 systematic reviews. These reviews reported on 15 other studies, including several randomized, double-blind clinical trials. Several inconsistencies were detected both in the design of these studies and in their outcomes, as pointed by the authors of the reviews. The two reviews acknowledge a lack of enough evidence to support the supplementation with vitamin D in the treatment of low back pain (SORT C).
Conclusion: As conclusion, this work shows that there is still a lack of scientific evidence to support the recommendation of vitamin D intake for the treatment of chronic low back pain. The heterogeneity present in some studies and the inconsistencies found in some of the results seems to severely impact this conclusion, which, therefore, reveals that there is a need for more research and more scientific soundness in this area.
