Evaluating Inflammatory Versus Mechanical Back Pain in Individuals with Psoriatic Arthritis: A Review of the Literature

Abstract: Psoriatic arthritis (PsA) is a chronic immune-mediated disease characterized by psoriatic skin and nail changes, peripheral joint inflammation, enthesitis, dactylitis, and/or axial involvement, either alone or in combination with each other. The presence of axial involvement has been shown to be a marker of PsA severity; however, there is no widely accepted definition of axial involvement in PsA (axPsA) or consensus on how or when to screen and treat patients with suspected axPsA. Chronic back pain is a promin… Show more

“…Patients often complain of long-standing back pain with an insidious onset before any other symptoms. The rheumatologist needs to differentiate between inflammatory back pain (IBP) and mechanical back pain (MBP), as both of them may occur in axPsA patients and their accurate differentiation allows for appropriate treatment administration [ 30 , 37 ] ( Table 2 ). Patients with IBP usually complain of lower back stiffness in the morning for at least 30 min, with no improvement at rest, sometimes waking patients at night or early in the morning, with an improvement in symptoms after starting physical activity and a good response to non-steroidal anti-inflammatory drugs (NSAIDs) [ 15 ].…”

“…However, there is limited, clear evidence of LBP and arthritis interaction. Non-mechanical causes, such as rheumatologic origin, lead to increasing pain severity [ 16 ]; moreover, mechanical LBP was associated with low physical activities, psychological symptoms, and functional limitations [ 17 ], which are significant moderate associations in people with rheumatoid arthritis [ 18 , 19 , 20 ]. Although there are conflicting results of inflammatory indicators in people with LBP, most previous studies indicated inflammatory components in people with LBP [ 21 ].…”

“…To screen for peripheral arthritis, practitioners should evaluate patients for swelling and tenderness, which can be indicative of synovitis and inflammation, as well as commonly affected joints, such as feet and hands, knees, wrists, ankles, and shoulders [24]. Axial arthritis can be an indicator of higher disease severity [49] and commonly presents with slowly developing inflammatory back pain (IBP) [50][51][52]. IBP is defined by the Assessment of SpondyloArthritis international Society as chronic back pain for at least 3 months, with onset before the age of 40 years, pain that causes waking during sleep, and stiffness that improves with activity [53][54][55].…”

“…IBP is defined by the Assessment of SpondyloArthritis international Society as chronic back pain for at least 3 months, with onset before the age of 40 years, pain that causes waking during sleep, and stiffness that improves with activity [53][54][55]. Since patients present with back pain in general medicine settings for a variety of reasons [56], it is important to distinguish IBP from mechanical back pain, the latter of which is an injury or structural abnormality in the lower back [50,57]. Axial PsA is associated with a particularly high incidence of sacroiliitis, which can present as bilateral and symmetric, based on genetic status (HLA-B27).…”
