Pharmacological treatment has been gradually enriched by a variety of compounds; however, no single drug is capable of fully managing the constellation of fibromyalgia (FM) symptoms. Currently, it is not possible to draw definite conclusions concerning the best pharmacological approach to managing FM because results of randomized clinical trials present methodological limitations and therapeutic programs are too heterogeneous for adequate comparison. ⋯ In this review, we will evaluate those pharmacological therapies that have produced the most significant clinical results in treating FM patients. The nature of FM suggests that an individualized, multimodal approach that includes both pharmacologic and nonpharmacologic therapies seems to be the most appropriate treatment strategy to date.

Cryoglobulinemia refers to the presence in serum of immunoglobulins, that reversibly precipitate at low temperatures. Cryoglobulins are classified according to their immunochemical properties as type I, composed of a single monoclonal immunoglobulin, and types II and III, referred as mixed cryoglobulinemia (MC), composed by a mixture of monoclonal (type II) and polyclonal (type III) IgM that have rheumatoid factor activity and bind to polyclonal IgGs. MC is a systemic vasculitis with cutaneous and multiple organ involvement including chronic hepatitis, membrano-proliferative glomerulonephritis, and peripheral neuropathy. ⋯ Patients with HCV-related MC may be managed by means of etiological, pathogenetic or symptomatic therapeutic modalities. The choice of the more appropriate treatment is strictly related to the assessment of disease activity, and to the extent and severity of organ involvement. This paper reviews the currently available therapeutic strategies for MC syndrome, emphasizing the importance of HCV eradication, and the safety/efficacy of new biologic therapies for selective control of cryoglobulin-producing B-cells.

Fibromyalgia syndrome (FMS) is a common chronic condition of widespread pain with causal mechanisms that are largely unknown. It is characterized by moderate to severe musculoskeletal pain and allodynia, but its pathogenesis appears confined to the nociceptive structures of the central nervous system. FMS is often triggered by negative environmental influences, especially if they occur in childhood. ⋯ Central sensitization has long been associated with FMS pain. It describes enhanced excitability of dorsal horn neurons, which leads to transmission of altered nociceptive information to the brain. Understanding of pathogenetic pathways in FMS has advanced beyond observing patient responses to neurophysiologically targeted therapies and basic research.
