|
Fibromyalgia (26) Healthy controls (26) |
Cytokines (IFN-y, IL-2, IL-4, IL-6, IL-10). |
IL-6: Mean increase of 242.8% in the patient group when compared to healthy controls. The level of IL-6 correlates directly with the severity of pain. IL-4: Mean increase of 136.4% in the patient group when compared to healthy controls. Anti-inflammatory cytokines: There was a statistically significant decrease among the patient group when compared to healthy controls. |

|
Chronic pelvic pain (32) Healthy controls (37) |
Testosterone; MIF (factor of inhibition of the migration of macrophages); cytokines (TNF-α, TNF-β, IL-2, IL-1β); salivar cortisol. |
MIF: Significantly higher in patients than in control. Testosterone: Less in patients than in control TNF-α: significantly higher in patients than in control. |

|
Burning mouth Syndrome (47) Healthy controls (47) |
Adrenaline; noradrenaline; ACTH; plasma cortisol. |
Adrenaline: significantly lower in patients. Depression levels significantly associated with plasma levels of noradrenaline and cortisol. |

Fibromyalgia (105) |
Cytokines (IL-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-10, IL-12, IL-13, IL -17, G-CSF, GM-CSF, IFN-y and TNF-α); chemokines (CXCL8, CCL2 (MCP1) e CCL4 (MIP1β)). |
There were no significant correlations between cytokine levels and fatigue, depression or stress; there is a trend of significance when we compare levels of cytokines and pain. After post-hoc analysis, there was a marked reduction of IL-4, IL-5, and IL-13 cytokines. |

RNA expression: deregulation of miRNA in VBD affects relevant estrogen pathways, whereas, in generalized pain, it is related to muscle, nerve cells, and glial cells. IL-8 and IL-1ra were statistically significant between the groups, being higher in the patient group. Women with VBD and VBD + IBS have increased expression of proinflammatory cytokines. |
