Antibiotics were discontinued given that these findings were inconsistent with pyogenic arthritis

They also recognized a range of associated disorders, including SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, and osteitis), PAPA syndrome (pyogenic arthritis
, pyoderma gangrenosum, and acne), and PASH (pyoderma gangrenosum, acne, and hidradenitis suppurativa).

Certain syndromes, in which HS is a part of the clinical picture, are precisely defined, for example, pyogenic arthritis

, Pyoderma gangrenosum and Acne (PAPA) and others have been noted earlier, too.

SAIDs presenting with nonbacterial pyogenic manifestations include pyogenic arthritis
, pyoderma gangrenosum and acne (PAPA) syndrome, deficiency of the IL-1-receptor antagonist, deficiency of the IL-36 receptor antagonist, Majeed syndrome, and chronic recurrent multifocal osteomyelitis.
To date, there are twelve known MAISs: familial Mediterranean fever (FMF); tumor necrosis factor receptor-associated periodic syndrome (TRAPS); cryopyrin-associated periodic syndrome (CAPS), a group which includes familial cold urticaria syndrome (FCAS), Muckle-Wells syndrome (MWS), and chronic infantile neurological cutaneous articular (CINCA) syndrome; mevalonate kinase deficiency (MKD); NLRP12-associated autoinflammatory disorder (NLRP12AD); granulomatous MAISs which include Blau syndrome (BS) and early-onset sarcoidosis (EOS); and, finally, the hereditary pyogenic disorders including PAPA (pyogenic arthritis
, pyoderma gangrenosum, and acne) syndrome, Majeed syndrome (MS), and deficiency of the IL-1 receptor antagonist (DIRA).
in infants and children: a review of 95 cases.
Familial cases of SAPHO syndrome have been described (15,16); however, genetic analyses fail to demonstrate variations in the coding regions or splice sites of genes known to cause auto-inflammatory bone disorders (e.g., Majeed syndrome, murine CRMO and cherubism), other skin inflammatory disorders (e.g., PAPA syndrome: pyogenic arthritis
, pyoderma gangrenosum, and acne), and mutations in NADPH oxidase (NCF4 gene).
