More opioids, more pain: Fueling the fire

For more than a century, clinicians have noticed a paradoxical phenomenon: certain patients who are taking opioids (which are supposed to numb pain) become more sensitive to pain than those who are not taking opioids. The earliest observation of this phenomenon can be traced back to the British physician Sir Clifford Allbutt, who, in 1870, described it: “at such times I have certainly felt it a great responsibility to say that pain, which I know is an evil, is less injurious than morphia, which may be an evil. Does morphia tend to encourage the very pain it pretends to relieve?” Research studies and clinical observations over the years have identified the phenomenon Dr. Allbutt noticed as opioid-induced hyperalgesia (OIH). What is opioid-induced hyperalgesia? Hyperalgesia is an increased pain response from a stimulus (cause) that usually provokes a minor pain response. For example, getting your blood drawn for lab testing usually causes mild discomfort, but this common medical procedure would be very painful for certain patients who are taking opioids chronically. OIH is a lesser known side effect of long-term opioid therapy, but a serious one, and yet another reason doctors should carefully select who may benefit from extended use of these pain medications. What causes OIH? The mechanism behind opioid-induced hyperalgesia is complex and involves molecular and chemical changes in the brain and spinal cord. Opioids tend to activate specific receptors that block pai...

Authors: Moll SA, Wiertz IA, Vorselaars AD, Zanen P, Ruven HJ, van Moorsel CH, Grutters JC Abstract Aim: Cancer antigen 15-3 (CA 15-3) is a baseline biomarker in idiopathic pulmonary fibrosis (IPF), but its value during follow-up is unknown. Materials and methods: Associations between serum CA 15-3 and pulmonary function tests during 1-year follow-up were evaluated by a mixed model in 132 IPF treated with pirfenidone or nintedanib. Results: Increased baseline (median: 56 kU/l) and follow-up CA 15-3 levels were inversely associated with forced vital capacity and diffusing capacity of the lung for carbon monoxid...

Authors: van Campen C(MC, Rowe PC, Verheugt FWA, Visser FC Abstract OBJECTIVES: Muscle pain and fibromyalgia (FM) are common among individuals with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). We recently demonstrated that during orthostatic stress testing, adults with ME/CFS reported increased pain. In the current study, we hypothesised that pain pressure thresholds (PPT) would decrease and temporal summation (windup) would increase after head-up tilt testing (HUT), and that the presence of co-morbid FM would be associated with greater change in both measures. METHODS: We studied adult ME/CFS p...
