OBJECTIVE We aimed to investigate if aberrant intracellular production of NADPH oxidase-derived reactive oxygen species (ROS) in neutrophils is a disease mechanism in the autoinflammatory disease SAPHO syndrome, characterized by synovitis, acne, pustulosis, hyperostosis and osteitis, as has previously been suggested based on a family with SAPHO syndrome-like disease. METHODS Neutrophil functi...

RATIONAL SAPHO (Synovitis-Acne-Pustulosis-Hyperstosis-Osteitis) syndrome is a rare disease featured by its dermatological and osteoarthritic disorders, the latter of which mainly affecting the anterior chest wall, spine, and sacroiliac joint. However, rheumatoid arthritis (RA) is a chronic autoimmune disease, mainly affecting the synovial tissue of small joints in hands and feet. Here, we prese...

OBJECTIVE The aetiology of SAPHO (synovitis, acne, palmoplantar pustulosis, hyperostosis, osteitis) syndrome seems to involve genetic, infectious and immunological components. We examined innate and adaptive immune responses in SAPHO syndrome, as compared with PsA and RA. We also studied the effect of etanercept on immunological parameters. METHODS We studied 29 patients with SAPHO syndrome, ...

OBJECTIVE To describe the presence of Propionibacterium acnes (P. acnes) in a series of patients with SAPHO syndrome in which a bone biopsy has been carried out and to discuss the results comparing them to the data described in the literature. METHODS In 6 out of 56 patients with SAPHO syndrome, a bone biopsy from osteitic lesion was carried out. This invasive investigation was performed only...

SAPHO syndrome is a rare and often unrecognized disease with prominent inflammatory cutaneous and articular symptoms characterized by musculoskeletal manifestations (synovitis, hyperostosis, osteomyelitis) associated with dermatological conditions (severe acne and pustulosis). The acidic soluble fraction of whole saliva from 10 adult women affected by SAPHO syndrome and from a group of 28 healt...

BACKGROUND AND PURPOSE Imaging findings in patients with a combination of synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) are often misinterpreted as discitis/osteomyelitis or metastases, resulting in multiple biopsies and delayed diagnosis. We have incidentally noted a semicircular morphology in vertebral body imaging in several cases of SAPHO syndrome with vertebral involvemen...

OBJECTIVE To determine the frequency, clinical features, and radiological and bone scintigraphic changes of spondylodiscitis in patients with SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis). METHODS The study was retrospective. Data from patients with the diagnostic criteria of SAPHO syndrome were analysed for clinical features, biological data (HLA B antigen), and pelvic and ...

Introduction: Because SAPHO (Synovitis, Acne, Pustulosis, Hyperostosis and Osteitis) is a rare syndrome, its treatment is controversial. We are presenting a case of a patient with SAPHO syndrome, who was treated with combined drug regimen. Case Report: A 16year-old man was admitted to our hospital with hip and back pain for one month. The patient was not able to move his thighs; therefore he co...

A middle aged man presented with a 4 year history of painful swelling of both knees and pustular acne on his back. The MRI scan of the knees showed gross synovitis, so did the histopathology of the synovium. A diagnosis of SAPHO syndrome was made and he was treated with IV pamidronate. His pain reduced and acne completely cleared up on therapy. A dermatologist has rarely made a diagnosis of SAP...
