This paper is a case report describing PsAPSASH syndrome, presented as an alternative phenotype within the spectrum of syndromic hidradenitis suppurativa, and it reports treatment with the IL-17A inhibitor secukinumab. The authors document the patient’s clinical features consistent with the syndrome and describe outcomes during secukinumab therapy. Because this is a single-patient case report, the findings cannot be generalized beyond the individual and there are no controlled comparisons to other therapies or to placebo. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Syndromic hidradenitis suppurativa (HS) is a form of symptom constellations, which differs from the familial and genetic form and comprises predominantly osteoarticular manifestations. Many forms include pyoderma gangrenosum and acne (PASH), pyogenic arthritis (PAPASH), spondyloarthritis (PASS) and psoriatic arthritis (PsAPASH) and are categorized in the autoinflammatory syndromes. Anti-TNF-α and anti-IL-1a blockade are between the therapeutic approaches that improve skin symptoms and prevent permanent osteoarticular damage. This case report refers to the successful treatment of a mixed phenotype of the aforementioned symptoms using the IL-17A inhibitor secukinumab after initial treatment with adalimumab. The therapy improved both cutaneous and reported osteoarticular symptoms. Different approaches for these recalcitrant HS syndromes are essential in order to achieve long-term remission for those patients.

Significant increase of proinflammatory cytokines IL-1β, TNF-α, IL-17 and the antiinflammatory cytokine IL-10 has been detected in lesional and perilesional skin. 2 , 3 Apart from sporadic cases, there is a genetic background for certain HS patients, correlating with mutations in the γ-secretase genes nicastrin, presenilin enhancer 2 and presenilin. 4 HS has been described in association with several clinical syndromes that include comorbid disorders, such as pyogenic arthritis (PA), pyoderma gangrenosum (PG), acne, ulcerative colitis (UC) and psoriatic arthritis. Such syndromes include the triad of PG, acne and HS (PASH) alone or in combination with PA (PAPASH) or psoriatic arthritis (PsAPASH). In addition, HS can also be a feature of other syndromes such as the SAPHO syndrome, 5 which appear recalcitrant to treatment, even after the use of various biologics, such as anti-TNF and anti-IL-1. Here we describe a patient with a novel phenotypic variant of the syndromes described, who responded to treatment with the IL-17A inhibitor secukinumab.

Plantar pustulosis before (1h) and after secukinumab treatment (1i). Figure 2. Bone scan revealing a “bull’s head” sign-like radiopharmaceutical accumulation of the costoclavicular region (2a, red arrow) and of the wrist joints (2b). (2c): histopathologic evaluation of palmar pustular eruptions revealed characteristic microabscesses of subcorneal neutrophilic accumulation. (2d): Histology of the lower-leg ulcerations demonstrated diffuse neutrophilic inflammation as a hallmark of pyoderma gangrenosum. Case A 50-year-old female, Caucasian, unemployed patient was admitted to our departments suffering from HS. The patient reported a disease onset of 25 years, describing exacerbations with relapsing nodules, abscesses, and draining sinus tracts. Among the risk factors correlated with the disease, the patient was obese (BMI = 36) and a smoker (34-pack years). Moreover, she had a positive familial history, with her maternal grandmother having had severe refractory HS. Sequencing of the γ-secretase gene complex did not reveal any relevant mutations. The patient reported to having up to 10-15 stools daily. A colonoscopy was performed three years ago, which excluded inflammatory bowel disease. Twelve years after being diagnosed with HS, the patient developed acne conglobata (AC), which was treated without systemic therapy. In addition, she underwent numerous incisions and radical excisions, antibiotic treatment with doxycycline, and the combination of clindamycin and rifampicin over 3 months, according to the HS treatment guidelines, 1 , 2 without sustained remission of the lesions. A previous 1-year therapy with isotretinoin did not improve the HS lesions. The patient was included in a clinical trial combining weekly administration of 40 mg adalimumab s.c. vs. placebo for 3 months, followed by continuation of adalimumab treatment in the same dose over 15 months. After this period, the patient was lost to follow-up. She described an improvement of the HS lesions and reduction of flares under adalimumab. During this time, her general practitioner discontinued adalimumab treatment, judging that the treatment lacked efficacy. One month after discontinuation of adalimumab, the patient developed confluent erythematous pustules on the palms ( Figure 1a ) and soles ( Figure 1h ) with psoriasis-like scaling of the lesions followed by intermittent shoulders and knee pain and swelling. We performed a bone scan, which showed intense radiopharmaceutical accumulation of the left knee ( Figure 2a ) and the wrist joints showed signs of arthritis and synovitis ( Figure 2b ), with no typical pattern of psoriatic arthritis. The pattern of the bull’s head sign ( Figure 2a , red arrow) was detected, usually identified as a pathognomonic sign of SAPHO syndrome. 1 The patient did not admit having a pain or recurrent swelling of the costoclavicular region or back pains. No typical signs of osteitis were detected. Dermatohistology of the palmoplantar lesions revealed characteristic neutrophilic abscesses, compatible with pustular psoriasis ( Figure 2c ). Two months after therapy discontinuation, single, disseminated, painful pustules appeared on both thighs and lower legs ( Figure 1e ), which progressed to painful ulcers ( Figure 1f ) with elevated violaceous margins. The histopathological evaluation confirmed a PG ( Figure 2d ). Based on the disease pathophysiology, we initiated therapy with secukinumab 300 mg s.c weekly for the first month and then monthly thereafter. Before the initiation of treatment the patient was reported to have an IHS4 score of 17 and a DLQI score of 23. Four months later, the patient demonstrated a significant remission of her HS lesions ( Figure 1d ) (ΔIHS4 9 and ΔDLQI 11), joint pains and pustular psoriasis ( Figure 1b , Figure 1i ), with only moderate improvement of her PG lesions. An epithelization was not observed. The PG showed no improvement and 100 mg prednisolone daily i.v. over three days was added to the treatment, which was subsequently tapered over one month. The treatment was followed by PG improvement ( Figure 1g ). Discussion HS can also be a main or secondary element of certain syndromes highlighted through their unique phenotypes, 5 known as autoinflammatory diseases (AID). AID manifests with recurrent sterile inflammation, while high autoantibody serum levels or antigen-specific lymphocytes are lacking. 6 – 9 These syndromes combine dermatological manifestations (HS, PPP, AC, PG), musculoskeletal disorders (arthritis, synovitis, hyperostosis, osteitis) and gastroenterological manifestations (ulcerative colitis, M. Crohn). Combinations lead to already described syndromes such as PASH, 10 , 11 PASS, 8 PAPASH, 10 PsAPASH 12 and SAPHO. 13 These disorders are characterized by aberrant release of IL-1β, which mediates the increase of tumor necrosis factor α (TNF-α), interferon γ (IFN-γ) and other chemokines, which are responsible for neutrophilic recruitment and might promote an anti-apoptotic microenvironment. 14 – 17 IL-17 also promotes neutrophilic recruitment and activation and has a synergistic effect with TNF-α. 18 An imbalance of the Th17/Treg lymphocyte ratio is believed to aggravate autoinflammation and was reported both in PG and HS independently. 19 , 20 Therapeutic combinations of TNF-α and IL-17 and/or IL-1β blocking agents might provide a solution for recalcitrant syndromic HS cases. 2 We describe a new syndromic HS-related phenotype (pustular Ps oriasis, A rthritis, P G, S ynovitis, A cne, S uppurative H idradenitis). The pathophysiology based on the dysregulation of IL-17 production provided the rationale for the treatment with the IL-17A inhibitor secukinumab. This unique phenotypic constellation could also be addressed as a variant of SAPHO syndrome. 3 Moreover, pustular lesions and PG could be explained as “paradoxical” reactions to the previous adalimumab treatment or its switch to a new biologic treatment. 4,5 Despite these promising results, long term follow-up for these patients and controlled clinical studies can determine if treatment with IL-17A inhibitors can result in long-term remission. 6 Moreover, this case underlines the role of the dermatologist in diagnosing such symptoms and leading a multidisciplinary approach for these patients. Dermatological manifestations can precede the osteoarticular or other organ symptoms and timely treatment initiation might avoid irreversible complications.

Continue reading READ ALL This is a very interesting report on a exemplary case of syndromic hidradenitis suppurativa, requiring a complex systemic treatment. While potentially interesting, there are some minor points to be addressed by the authors, to further improve an already well-written case report: 1. Regarding joint manifestations: it seems there is some minor uptake of radiotracer localized to the sacroiliac joints. Osteoarticular involvement strongly reminds the SAPHO pattern. Did the patient refer any back pain? Differential diagnosis with SAPHO should be discussed by the authors. 2. The authors propose a novel acronym for the reported case. In my opinion, the conclusion section should be more conservative, as there is no experimental (genetic, molecular, cytokine data etc.) supporting this concept. Furthermore, this is a heavily pre-treated patient with a long disease history of HS. Could be there be an association between the previous exposure to multiple drugs (retinoids, anti-TNFs, etc.) and the development of "paradoxical" autoinflammatory extracutaneous involvement (such as recalcitrant PG)? This could be a more interesting take on the case? Please include some additional references. 3. Treatment: the authors should better describe the take-home messages for the therapeutic management of such complex/severe disease phenotypes. Maybe, a combination treatment strategy for complex autoinflammatory disease phenotypes is more effective than monotherapy (i.e. secukinumab alone)? Please include some additional references on this such as: Garcovich et al. (2017) 1 . Jin et al. (2019) 2 . Tan et al. (2021) 3 . Is the background of the case’s history and progression described in sufficient detail? Partly Are enough details provided of any physical examination and diagnostic tests, treatment given and outcomes? Yes Is sufficient discussion included of the importance of the findings and their relevance to future understanding of disease processes, diagnosis or treatment? Partly Is the case presented with sufficient detail to be useful for other practitioners? Yes References 1. Garcovich S, De Simone C, Berti E, Marzano AV: Drug management of neutrophilic dermatoses.

Continue reading READ ALL Thank you for giving me the opportunity to review this really interesting case. This case report describes an mixed syndrome encountered in a patient initially suffering from HS and treated with secukinumab. The clinical, scintigraphic and histopathological images provided are of high quality. However I would like to add some details to the case description: The locations of the HS lesions on the patient's skin. Why is she unemployed? Because of HS? I would also add the initial severity assessment scores (IHS4 and DLQI) before secukinumab to better understand the improvement of symptoms with treatment. I would specify that the bull's head sign is typical of SAPHO syndrome to facilitate understanding of the case as not all doctors are experts in interpreting bone scans. Finally, I would add to the discussion that the initial response to secukinumab is promising but long-term follow-up of the patient is needed to assess long-term remission. Is the background of the case’s history and progression described in sufficient detail? Partly Are enough details provided of any physical examination and diagnostic tests, treatment given and outcomes?

The important differential diagnosis of the case being a variant of SAPHO syndrome including HS and a paradoxical reaction to the switch of the biologic(s) or to the previous adalimumab treatment were also addressed. An extensive opinion on combination of treatments (IL17/TNFα) or IL-1β was included but because of the lack of controlled studies - as Dr Garcovich mentioned in their article - it cannot have a strong recommendation level.

Not approved Fundamental flaws in the paper seriously undermine the findings and conclusions Thank you for giving me the opportunity to review this really interesting case. This case report describes an mixed syndrome encountered in a patient initially suffering from HS and treated with secukinumab. The clinical, scintigraphic and histopathological images provided are of high quality. However I would like to add some details to the case description: The locations of the HS lesions on the patient's skin. Why is she unemployed? Because of HS? I would also add the initial severity assessment scores (IHS4 and DLQI) before secukinumab to better understand the improvement of symptoms with treatment. I would specify that the bull's head sign is typical of SAPHO syndrome to facilitate understanding of the case as not all doctors are experts in interpreting bone scans. Finally, I would add to the discussion that the initial response to secukinumab is promising but long-term follow-up of the patient is needed to assess long-term remission. Is the background of the case’s history and progression described in sufficient detail? Partly Are enough details provided of any physical examination and diagnostic tests, treatment given and outcomes? Partly Is sufficient discussion included of the importance of the findings and their relevance to future understanding of disease processes, diagnosis or treatment? Partly Is the case presented with sufficient detail to be useful for other practitioners? Partly Competing Interests No competing interests were disclosed. Reviewer Expertise Hidradenitis Suppurativa I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above. reply Respond to this report Responses (1) Author Response 16 Jul 2021 Nikolakis Georgios We would like to thank Dr. Daxhelet for their comments and their valuable contribution to improve the manuscript We have mentioned the initial HS scores. Unemployment was not correlated with HS. The localization of the lesions was highlighted. We added the comment about the bull's head sign and its correlation with SAPHO syndrome.
