An immune-mediated inflammatory disease (IMID) is any of a group of conditions or diseases that lack a definitive etiology, but which are characterized by common inflammatory pathways leading to inflammation, and which may result from, or be triggered by, a dysregulation of the normal immune response.[citation needed]
IMIDs are caused by massive production of inflammatory cytokines. This is believed to be the result of an abnormal immune response.[1][2]
Risk factors
IMIDs occur in genetically predisposed individuals, due to various environmental and host factors.[1][2] Some reviews include psychosomatic factors.[2]
Fatigue is a very commom symptom in IMIDs.[4][5][1][6][7] Fatigue often changes markedly within days and from day to day.[8]
IMIDs negatively effect organs and systems (including peripheral and central nervous systems) which may cause chronic fatigue, pain, skin manifestations, multiorgan dysfunction and sleep disturbance effects.[1][2] Some IMIDs cause hyperalgesia (abnormal sensitivity to pain).[9][10][11][12]
Treatment and outlook
Meds, including biologics, help some IMID patients, although resistance may develop in time.[13] Other IMID patients are unresponsive or intolerant to current meds.[1]
