Objective

To review the epidemiology, presentation, diagnosis, treatment, pathogenesis, and genetics of the syndrome known under the acronym of SAPHO for Synovitis, Acne, Pustulosis, Hyperostosis, and Osteitis to heighten awareness of this entity.

Methods

We conducted a Medline search using SAPHO syndrome, chronic recurrent multifocal osteitis/osteomyelitis, and related terms as keywords and extracted further relevant articles from the retrieved references.

Results

The SAHPO acronym identifies a syndrome encompassing a variety of osteoarticular disorders that are frequently accompanied by dermatoses characterized by neutrophilic pseudoabscesses, but can also occur in isolation. SAPHO syndrome is rare, although probably underrecognized because its diagnosis may be challenging because of the wide variability in its musculoskeletal and cutaneous manifestations. This is especially true when atypical sites are involved and when specific skin lesions are absent. There are no standardized treatment protocols available. Current treatments are empirical and have the objective of providing relief from the at times debilitating pain associated with SAPHO syndrome. They include nonsteroidal anti-inflammatory drugs and analgesics as first-line agents. Systemic corticosteroids, disease-modifying anti-rheumatic drugs, biologicals targeting tumor necrosis factor alpha and interleukin-1, and bisphosphonates have all been beneficial in some patients, but ineffective in others. This suggests that the pathogenesis of SAPHO syndrome is multifactorial, but this aspect remains poorly explored, although bacteria and immunological dysfunction are hypothesized to play a role.

Conclusions

The early recognition, diagnosis, and prompt treatment of SAPHO syndrome can prevent the unnecessary use of long-term antibiotics or invasive procedures, while rapidly alleviating pain in a majority of affected patients.
