Introduction: Pain in both peripheral and axial joints is a major symptom in patients with psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA). Emerging evidence demonstrates pain mechanisms, beyond those related to inflammation or joint damage, based on aberrant processing of nociceptive stimuli peripherally as well as centrally. The Janus kinase/signal transducers and activators of transcription (JAK-STAT) signaling pathway has been implicated in the processing of pain beyond its role in mediating inflammation and inhibitors of this pathway approved for the treatment of axSpA and PsA have been shown to alleviate a broad array of pain outcomes in both axial and peripheral joints.
Areas Covered: We review recent definitions and standardization of the nomenclature for categorizing chronic pain according to causality, assessment tools to evaluate nociplastic pain, the pathophysiologic role of JAK-STAT signaling in nociplastic pain, evidence for the presence of nociplastic pain in axSpA and PsA, and the impact of JAK inhibitors (JAKi) on pain outcomes in clinical trials (PubMed: 01/01/2019-04/01-2024).
Expert Opinion: Nociplastic pain assessment has been confined almost entirely to the use of a limited number of questionnaires in cross-sectional studies of these diseases. Though effective for alleviating pain, it is unclear if JAKi specifically impact nociplastic pain.

Fibromyalgia (FM) is a complex and multifaceted condition characterized by a range of clinical symptoms, including widespread pain and a strong association with migraine headaches. Recent findings have underscored the role of oxidative stress and transient receptor potential ankyrin 1 (TRPA1) channel in migraine and FM. However, the precise mechanisms underlying the comorbidity between migraine and FM are unclear.

Chronic ocular surface pain (COSP) refers to interrelated symptoms such as burning, aching, and irritation and can occur as an isolated condition or comorbid with numerous ocular disorders, including dry eye syndrome Treatments for COSP are largely aimed at the ocular surface and modulating pain arising from damaged corneal nerves; however, the average impact of these treatments on COSP are low to absent. A potential explanation for this is that, in a subset of patients with COSP, individuals have amplified and/or dysregulated neural signaling and sensory processing within the central nervous system (CNS). As in other chronic pain conditions, this might be the pathogenic mechanism primarily responsible for maintaining pain - a phenomenon now referred to as nociplastic pain.

Introduction: Chronic postsurgical pain (CPSP) represents a widely underdiagnosed and often poorly treated medical problem, affecting 10-50% of all surgical patients, exhibiting neuropathic features in 35-60%. It is hypothesised that surgery-induced tissue damage and the subsequent immune response cause sensory alterations in the early postoperative period, ultimately leading to a chronic neuropathic or nociplastic pain state. The 'Sensory Changes and Immunological parameters in Postsurgical pain' study (SCIP-Pain study) was designed to test this hypothesis and identify sensory alterations and changes in the immunological response that are related to the development of CPSP with neuropathic features.

Endometriosis is an inflammatory chronic condition associated with nociceptive, neuropathic, and nociplastic pain. Central sensitization (CS) is the primary nociplastic pain mechanism. However, there are currently no standardized methods for detecting CS or nociplastic pain.
