    Abstract: 〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 Hidradenitis suppurativa (HS) is a chronic skin disease characterized by inflammatory nodules and abscesses. The pathogenic role of bacteria is not fully understood. As the diagnosis is usually delayed, patients are often treated with several lines of antibiotics in a nonstandardized fashion. The aim of the study was to investigate and compare the bacteriology of active HS lesions in patients treated or not treated with antibiotics in the community setting before referral to a dedicated HS clinic. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 Purulent skin lesions of patients with HS referred to the HS Clinic of Rabin Medical Center in 2009–2020 were cultured. Data were collected from the patients’ medical files and microbiology reports. The correlation between the location of the skin lesion and the bacteriologic profile was analyzed, and the effects of previous antibiotic treatment on the bacteriologic profile of the lesions and susceptibility patterns of the cultured bacteria were evaluated. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Pus (or tissue) from inflammatory lesions of 97 patients with HS was cultured. Mean (SD) patient age was 39.5 (13.0) years, and mean delay in diagnosis was 7.3 (8.3) years. Most patients (57.7%) had dominant involvement of one location, with the most active lesions concentrated in the genitalia, gluteal/perineal area, and axilla. Enterobacterales species were the most frequent isolates detected in all locations except the face and scalp. Seventy-eight patients (80.4%) had been treated in the community setting prior to referral with a median (range) of 2 (1–8) lines of antibiotics. The most commonly prescribed antibiotics were amoxicillin/clavulanate (22.0%), doxycycline/minocycline (16.8%), clindamycin (16.2%; monotherapy 8.1%, clindamycin with rifampicin 8.1%), and cephalexin (13.9%). Compared to the previously untreated patients, cultures of lesions from the previously treated patients yielded a higher percentage of gram-negative Enterobacterales (the most common isolates in this group) (31.3% vs. 10.3%) and a significantly higher median number of isolates per culture (2 vs. 1, 〈 i 〉 p 〈 /i 〉 & #x3c; 0.0001). Gram-positive bacteria, usually considered contaminants (mainly coagulase-negative staphylococci 〈 i 〉 ) 〈 /i 〉 accounted for 31.0% of the isolates in the previously treated group. Susceptibility testing for the entire cohort revealed 100% bacterial sensitivity to ciprofloxacin 〈 i 〉 . Staphylococcus 〈 /i 〉 spp. were 100% sensitive to rifampicin. Both gram-positive and gram-negative bacteria had high sensitivity to trimethoprim and sulfamethoxazole. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 Nonstandardized antibiotic treatment of HS in the community setting can skew the microbiology of skin lesions toward gram-negative bacteria. Therefore, treatment with trimethoprim and sulfamethoxazole or ciprofloxacin, either alone or combined with rifampicin, may be considered.

    Abstract: Treatment for hidradenitis suppurativa is diverse, yet frequently unsatisfactory. The aims of this study were to create a reproducible artificial intelligence-based patient-reported outcome platform for evaluation of the clinical characteristics and comorbidities of patients with hidradenitis suppurativa, and to use this to grade treatment effectiveness. A retrospective patient- reported outcome study was conducted, based on online questionnaires completed by English-speaking patients registered to the hidradenitis suppurativa StuffThatWorks® online community. Data collected included patient characteristics, comorbidities and treatment satisfaction. These were recoded into scalable labels using a combination of machine learning algorithm, manual coding and validation. A model of treatment effectiveness was generated. The cohort included 1,050 patients of mean ± standard deviation age 34.3 ± 10.3 years. Greater severity of hidradenitis suppurativa was associated with younger age at onset (p  〈  0.001) and male sex (p  〈  0.001). The most frequent comorbidities were depression (30%), anxiety (26.4%), and polycystic ovary syndrome (16.6%). Hurley stage I patients rated topical agents, dietary changes, turmeric, and pain relief measures more effective than tetracyclines. For Hurley stage II, adalimumab was rated most effective. For Hurley stage III, adalimumab, other biologic agents, systemic steroids, and surgical treatment were rated more effective than tetracyclines. Patients with hidradenitis suppurativa often have comorbid psychiatric and endocrine diseases. This model of treatment effectiveness provides a direct comparison of standard and complementary options.
