RESUMEN
BACKGROUND: ConclusionFibromyalgia is a chronic pain disorder characterized by diffuse musculoskeletal pain, fatigue, sleep disturbance and cognitive impairment. OBJECTIVE: A significant number of fibromyalgia patients do not respond adequately to the current drugs approved by the Food and Drug Administration (FDA) for fibromyalgia treatment including pregabalin, milnacipran, duloxetine. Thus, there is still a need for adjunctive therapies. METHOD: Naltrexone is an opioid receptor antagonist used to treat alcohol and opioid dependence. It is hypothesized that low dose naltrexone causes transient blockade of opioid receptors centrally resulting in a rebound of endorphin function which may attenuate pain in fibromyalgia. RESULTS: Two small prospective pilot studies have previously shown that treatment with low dose naltrexone may be an effective, safe, and inexpensive treatment for fibromyalgia. CONCLUSION: This prospective study lends further support to the preliminary body of evidence that naltrexone is a well tolerated and likely effective treatment option in the community setting. Further large prospective controlled trials are still needed.

Fibromyalgia (FM) is a characterized by generalized pain with widespread tender points in specific areas and is frequently accompanied by fatigue, stiffness, and a non-restorative sleep pattern. In the current retrospective study, we identified a subgroup of FM patients who had clinically important markers of inflammation. The study also explored the use of the original American College of Rheumatology (ACR) criteria in the diagnosis of FM. Our data suggested there was a distinct subset of patients with FM who had positive ESR, CRP, ANA and RF; a group that we considered representative of inflammatory FM. None of the FM patients in this study developed a documented coexisting autoimmune illness during the retrospective review period. The existence of FM subgroups further puts into question the already controversial use of either the new or old ACR classification criteria in the diagnosis of FM, as they do not address the issue of systemic inflammation which appears to be significant.

Zoledronic acid is used in the treatment of osteoporosis. Giant cell artertitis may lead to vision loss. We report a case in which vision loss occurred after zoledronic acid infusion.
