Abstract
Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome is a rare autoinflammatory disease characterized by dermatological disorders and osteoarticular inflammatory lesions. This article reviews the application of biologics and other treatments based on the therapeutic target and the size of molecules in SAPHO syndrome. We found that drugs, especially biologics, have different effects on bone, joint, and skin damage. This may relate to the different inflammatory pathways involved in the osteoarticular and cutaneous symptoms in SAPHO patients. In this study, we provide stratified medication recommendations for SAPHO syndrome. Patients with osteoarticular symptoms can consider tumor necrosis factor blockers, JAK inhibitor, interleukin (IL)-1 inhibitor, and IL-17 inhibitor. Patients with cutaneous symptoms should consider IL-17 and JAK inhibitors. Apremilast, Tripterygium wilfordii Hook F, and bisphosphonates are other effective treatments.

Abstract
Autoinflammatory syndromes are a steadily growing group of inflammatory diseases caused by abnormal regulations of the innate immune system. The clinical presentation is multifaceted, but recurrent fever, skin involvement, joint inflammation and other systemic symptoms of inflammation are characteristic. In contrast to classic autoimmune diseases, autoantibodies or specific T cells are not involved in the pathogenesis. In fact, innate immunity plays the most important role in autoinflammation. While activation of the innate immune system is usually self-limiting in healthy individuals, mutations and dysregulation can lead to chronic and excessive activation of innate immune responses and to the development of autoinflammatory diseases.

The effectiveness of treatments for patients with SAPHO syndrome: a follow-up study of 24 cases from a single center and review of literature. Clin Rheumatol 2020; 40:1131-1139. [PMID: 32789818 DOI: 10.1007/s10067-020-05322-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 07/10/2020] [Accepted: 08/04/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVES To evaluate the effectiveness of current treatments for SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, and osteitis) by delineating the therapeutic choices and the outcome of patients in a medical center of China and review of the literature. METHOD An observational study was performed on patients diagnosed as SAPHO syndrome in the Peking University First Hospital from 2009 to 2015. Clinical data including osteoarticular and cutaneous manifestations, laboratory and medical imaging findings, treatments, and outcomes were analyzed retrospectively. A literature detailing the usage of medicines and SAPHO syndrome patient responses to treatment were selected. RESULTS Clinical data of 24 patients were analyzed in this study. The mean age was 42.4 ± 15.5 years old at the time of diagnosis. Of a total of 17 patients that received the combination treatments of NSAIDs and DMARDs, 15 of them experienced an improvement in their symptoms. Bisphosphonates were given to 18 patients. Four patients were treated with TNF blockers, and one of them had adalimumab ineffective and then improved by add-on of DMARDs. The mean follow-up period was 2.5 years. Twenty-one patients (87.5%) had a favorable outcome and exhibited improved disease condition in the last follow-up. CONCLUSIONS The majority of patients with SAPHO syndrome respond well to combination therapy of NSAIDs, DMARDs, and bisphosphonates. TNF blockers are effective in a patient refractory to NSAID and DMARDs. However, in case TNF blockers are ineffective, add-on of DMARDs may be effective. Thus, the proper application of conventional DMARDs is still worth a position in the treatment of SAPHO syndrome. Key Points •NSAIDs and DMARDs and/or bisphosphonates can alleviate symptoms of the majority of patients with SAPHO syndrome. •TNF blockers are effective in patients who do not respond well to NSIADs and DMARDs. •In case TNF blockers are ineffective, add-on of conventional DMARDs may be effective.

Abstract
SAPHO (synovitis-acne-pustulosis-hyperostosis-osteitis) syndrome is a chronic inflammatory disease involving multiple organs such as skin and bones. At present, its etiology and pathogenesis are still unclear. Due to the variety of clinical manifestations and the small number of SAPHO syndrome involving the mandible, accurate diagnosis is difficult for oral and maxillofacial surgeons. Here, the authors report that a male patient with SAPHO syndrome involving the maxillofacial skin and mandible, followed for 3 years. We used Tc-MDP (technetium-99 conjugated with methylene disphosphonate) (commercially known as Yunke) to treat this disease and achieved significant clinical treatment. This suggests that Tc-MDP can be used as a bisphosphonate to treat SAPHO syndrome.

Abstract
Chronic non-bacterial osteomyelitis (CNO), chronic recurrent multifocal osteomyelitis (CRMO) and synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome are autoinflammatory disorder(s) in which sterile osteomyelitis is frequently accompanied by inflammatory conditions of the joints, skin, or intestine. Patients with CRMO commonly have a personal or family history of psoriasis, inflammatory bowel disease, and inflammatory arthritis, suggesting shared disease pathogenesis. Work by our group and others has demonstrated that dysregulation of interleukin-1 (IL-1) signaling can drive sterile osteomyelitis in the two human monogenic forms of the disease. Recent work in the chronic multifocal osteomyelitis (cmo) mouse model demonstrates that the disease is IL-1-mediated, that neutrophils are critical effector cells and that both caspase-1 and caspase-8 play redundant roles in mediating the cleavage of pro-IL-1β into its biologically active form. Recent data in the cmo mouse demonstrate that dietary manipulation alters the cmo microbiome and can prevent the development of osteomyelitis. Further investigation is needed to determine the specific components of the diet that result in protection from disease and if this finding can be translated into a treatment for human CRMO.

Abstract
The synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome includes a group of chronic, relapsing, inflammatory musculoskeletal disorders with similar manifestations, in particular synovitis, hyperostosis, and osteitis, which may or may not be associated with neutrophilic skin eruptions such as palmoplantar pustulosis and acne conglobata. The syndrome occurs at any age, can involve any skeletal site, and its imaging appearances are variable, depending on the stage/age of the lesion and imaging method. The diagnosis is difficult if there is no skin disease. Awareness of the imaging appearances, especially in the spine, may help the radiologist in avoiding misdiagnosis (e.g., infection, tumor) and unnecessary invasive procedures, while facilitating early diagnosis and selection of an effective treatment. In this article, we provide an overview of the radiological appearances of SAPHO syndrome, focusing on the magnetic resonance imaging findings of vertebral involvement, and present relevant clinical and pathological features that assist early diagnosis.

Abstract
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.

Abstract
The authors describe a case of SAPHO syndrome with bacillus Calmette-Guérin (BCG) immunotherapy for bladder cancer. The patient had undergone transurethral resection (TUR) and was treated with BCG immunotherapy following TUR. Two years after treatment for bladder cancer, the patient had palmoplantar pustulosis, and in the past 1 month suffered from pain localised to the anterior chest wall. The bone scintigraphy showed a strong focal enrichment in the right chest wall, suggesting spondyloarthropathy rather than malignant disease. On the basis of clinical and scintigraphy findings, SAPHO syndrome was diagnosed. The patient was treated with topical therapy and non-steroidal anti-inflammatory drugs and symptoms improved. The authors suggest that SAPHO syndrome might be caused by an association with BCG immunotherapy.

Abstract
In 1987, synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome was proposed as an umbrella term for a group of diseases with similar musculoskeletal manifestations, in particular hyperostosis of anterior chest wall, synovitis, and multifocal aseptic osteomyelitis, observed in association with dermatologic conditions such as palmoplantar pustulosis, severe acne, and hidradenitis suppurativa. Despite recent advances in our understanding of the epidemiologic, pathophysiologic, and immunogenetic mechanisms involved in SAPHO syndrome, etiopathogenesis remains poorly understood. Propionibacterium acnes, the microorganism associated with acne, has been recovered on bone biopsy in some patients, but the possible pathogenetic role of an infectious agent in a genetically predisposed individual, resulting in exaggerated inflammatory response as "reactive osteitis," is a largely unproven hypothesis. The newly available whole-body MRI will assist early diagnosis by detecting multifocal osteitis lesions, some of them asymptomatic, in axial (anterior chest wall, spine, and jaws) and nonaxial sites. Moreover, outcomes are vastly improved by treatment with bisphosphonates and tumor necrosis factor-alpha antagonists.

Abstract
Introduction The acronym SAPHO was introduced in 1987 to unify the various descriptions of a seronegative arthritis associated with skin manifestations and to show synovitis, acne, pustulosis, hyperostosis, and osteitis with and without sterile multifocal osteomyelitis. The etiology of SAPHO syndrome is unknown, but an association with infection by semipathogenic bacteria like Propionibacterium acnes has been suggested. We conducted an interventional study of SAPHO patients receiving antibiotics. Methods Thirty-seven patients met the clinical criteria of SAPHO syndrome, 21 of them underwent a needle biopsy of the osteitis lesion, and 14 of them showed positive bacteriological cultures for P. acnes. Thirty patients (14 bacteriological positive and 16 without biopsy) were treated with antibiotics for 16 weeks. The activity of skin disease and osteitis were assessed by a physician using a scoring model (from 0 to 6). In addition, patients completed a Health Assessment Score (HAS, from 0 to 6). The erythrocyte sedimentation rate was determined and a MRI (of the osteitis lesion, radiologic activity score from 0 to 2) was performed in week 1 (W1), week 16 (W16), and week 28 (W28, 12 weeks after antibiotics). Results Twenty-seven patients continued the medication (azithromycin, n = 25, 500 mg twice a week; clindamycin, n = 1, 300 mg daily; or doxycycline, n = 1, 100 mg daily) for 16 weeks. After W16 the scores for MRI (1.5 to 1.1, P = 0.01), skin activity (3.2 to 1.2, P = 0.01), osteitis activity (4.0 to 2.1, P = 0.02), and HAS (3.3 to 2.1, P = 0.01) decreased significantly. However, this was followed by increasing values for MRI scores (1.2 to 1.4, P = 0.08), skin activity (1.2 to 1.7, P = 0.11), osteitis activity (1.9 to 2.7, P = 0.01), and HAS (2.2 to 3.3, P = 0.02) from W16 to W28. The comparison of the scores in W1 and W28 in these 12 patients showed no significant differences. Conclusions For the period of application, the antibiotic therapy seems to have controlled the disease. After antibiotic discontinuation, however, disease relapse was observed. SAPHO syndrome thus groups with other chronic inflammatory arthropathies with a need for permanent therapy.
