CRPS: what's in a name? Taxonomy, epidemiology, neurologic, immune and autoimmune considerations.

Reg Anesth Pain Med 2019 Mar;44(3):376-387

Department of Pain Management, Cleveland Clinic, Cleveland, OH 44024, USA

This account of the condition now termed complex regional pain syndrome (CRPS) spans approximately 462 years since a description embodying similar clinical features was described by Ambroise Paré in 1557. While reviewing its historical origins, the text describes why it became necessary to change the taxonomies of two clinical syndromes with similar pathophysiologies to one which acknowledges this aspect but does not introduce any mechanistic overtones. Discussed at length is the role of the sympathetic component of the autonomic nervous system (ANS) and why its dysfunction has both directly and indirectly influenced our understanding of the inflammatory aspects of CRPS.

Compared to limb pain of other origin, ultrasonographic osteodensitometry reveals loss of bone density in complex regional pain syndrome.

Pain 2019 Feb 8. Epub 2019 Feb 8.

Dept. of Endocrine Research, Medical Hospital I, BG University Hospitals Bergmannsheil Bochum.

Local osteopenia and altered bone metabolism are major complications of complex regional pain syndrome (CRPS), but quantitative assessment is difficult unless using X-ray or dual-energy X-ray absorptiometry. Ultrasound-based measurement of bone density (UBD) is a possible alternative, but has never been used to detect unilateral disease such as CRPS. Therefore, the main outcome measure of this prospective study was the diagnostic utility of UBD in patients with lower limb CRPS. Read More

Anaesthesist 2019 Feb;68(2):115-128

Klinik und Poliklinik für Neurologie, Universitätsmedizin der Johannes Gutenberg-Universität Mainz, Langenbeckstr. 1, 55101, Mainz, Deutschland.

The acute phase of complex regional pain syndrome (CRPS) is pathophysiologically characterized by an activation of the immune system and its associated inflammatory response. During the course of CRPS, central nervous symptoms like mechanical hyperalgesia, loss of sensation, and body perception disorders develop. Psychological factors such as pain-related anxiety and traumatic events might have a negative effect on the treatment outcome. Read More

The serum protease network - one key to understand Complex Regional Pain Syndrome pathophysiology.

Pain 2019 Jan 28. Epub 2019 Jan 28.

Department of Neurology, University Medical Centre of the Johannes Gutenberg University Mainz, Mainz, Germany.

Complex Regional Pain Syndrome (CRPS) develops after fracture. The acute CRPS phenotype resembles exaggerated inflammation which is explained by local and systemic activation of a pro-inflammatory network including peptides and cytokines. Epidemiologic data suggest that inactivation of the peptidase angiotensin converting enzyme (ACE) in patients treated for hypertension increases the odds to develop CRPS. Read More

Division of Rheumatology, Allergy and Clinical Immunology, University of California at Davis School of Medicine, United States. Electronic address:

Complex regional pain syndrome (CRPS) has been considered to be an autoimmune disease and there have been clinical trials with intravenous immunoglobulin. Often the etiology of the so-called CRPS diagnosis cannot be discerned and there are no validated instruments that provide functional metrics. The term complex regional pain syndrome (CRPS), coined in 1994 to describe patients in whom the pain is out of proportion to the injury, was actually a diagnosis proposed during the American Civil War, but was originally known as causalgia.

Treatment of peripheral pain with low-dose local anesthetics by epidermal, epithelial and periosteal application.

Local Reg Anesth 2018 11;11:129-136. Epub 2018 Dec 11.

Graf Biostatistics, CH-8400 Winterthur, Switzerland.

Objectives: The efficiency of local anesthetics (LAs) in the treatment of peripheral pain is commonly attributed to their capacity to block the axon conduction of sensory nerves. LAs even in non-blocking concentration suppress oscillations of the resting membrane potential. Spiking in sensory neurons is triggered by subthreshold membrane potential oscillations (SMPOs), which reach threshold and is maintained by depolarizing impulse after oscillations. Read More

Decreasing Pain Ratings in Chronic Arm Pain Through Changing a Virtual Body: Different Strategies for Different Pain Types.

J Pain 2018 Dec 16. Epub 2018 Dec 16.

Institut d'Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS), Barcelona, Spain; Event-Lab, Department of Clinical Psychology and Psychobiology, Universitat de Barcelona, Barcelona, Spain; ICREA, Barcelona, Spain; Departamento de Psicología Básica, Universitat de Barcelona, Barcelona, Spain. Electronic address:

Modifying the visual aspect of a virtual arm that is felt as one's own using immersive virtual reality (VR) modifies pain threshold in healthy subjects, but does it modify pain ratings in chronic pain patients? Our aim was to investigate whether varying properties of a virtual arm co-located with the real arm modulated pain ratings in patients with chronic arm/hand pain because of complex regional pain syndrome (CRPS) type I (without nerve injury) or peripheral nerve injury (PNI). CRPS (n = 9) and PNI (n = 10) patients were immersed in VR and the virtual arm was shown at 4 transparency levels (transparency test) and 3 sizes (size test). We evaluated pain ratings throughout the conditions and assessed the virtual experience, finding that patients with chronic pain can achieve levels of ownership and agency over a virtual arm similar to healthy participants.

The Role of the Peripheral Nerve Surgeon in the Treatment of Pain.

Neurotherapeutics 2019 Jan;16(1):9-25

Division of Plastic and Reconstructive Surgery, Washington University in St. Louis, St. Louis, MO, USA.

Pain is a frequent cause of physician visits. Many physicians find these patients challenging because they often have complicated histories, emotional comorbidities, confusing examinations, difficult problems to fix, and the possibility of factitious complaints for attention or narcotic pain medications. As a result, many patients are lumped into the category of chronic, centralized pain and relegated to pain management. Read More

Neurometabolite changes in patients with complex regional pain syndrome using magnetic resonance spectroscopy: a pilot study.

Neuroreport 2019 01;30(2):108-112

Emotional Information and Communication Technology Association, Seoul, Republic of Korea.

The aim of this study was to investigate distinct neurometabolites in the right and left thalamus and insula of patients with complex regional pain syndrome (CRPS) compared with healthy controls using proton magnetic resonance spectroscopy. Levels of N-acetylaspartate (NAA), N-acetylaspartylglutamate (NAAG), myo-inositol (ml), glutamine (Gln), glycerophosphocholine (GPC), glutathione (GSH), and alanine (Ala) relative to total creatine (tCr) levels, including creatine and phosphocreatine, were determined in the right and left thalamus and insula in 12 patients with CRPS compared with 11 healthy controls using magnetic resonance spectroscopy. Levels of NAAG/tCr and Ala/tCr were higher in patients with CRPS than in controls in the left thalamus. Read More

Functional autoantibody diseases: Basics and treatment related to cardiomyopathies.

Front Biosci (Landmark Ed) 2019 01 1;24:48-95. Epub 2019 Jan 1.

Berlin Cures GmbH Berlin, Knesebeckstrasse 59-61, 10719 Berlin, Germany,

In the 1970s, autoantibodies directed against G-protein-coupled receptors (GPCR, GPCR-AAB) were discovered. After receptor binding, GPCR-AAB trigger uncontrolled receptor mediated signal cascades, thus producing pathologies. Diseases associated with such functionally active autoantibody type (functional autoantibodies) can be called "functional autoantibody diseases". Read More
