Background/Objectives: Antibiotic (AB) therapy is the first step in managing hidradenitis suppurativa (HS). Knowledge of the local patterns of antimicrobial resistance is paramount for the appropriate selection of antimicrobials. This study aimed to assess the occurrence of antibiotic resistance in patients with HS. Methods: A cross-sectional study was conducted on 103 patients with HS seen at the Dermatology Department at the University Hospital of Heraklion, Heraklion, Crete, Greece, from January 2019 to December 2023, who were not on any antibiotics in the last three months. Results: A total of 103 patients with HS participated in this study. Purulent material from 139 skin lesions of these patients was swabbed, and 79.86% (111/139) tested positive for bacteria. Gram-positive isolates accounted for 73%, whereas Gram-negative isolates comprised 27%. Among the isolates, 85.1% were aerobes, and 14.9% were anaerobic. The most common bacterial families isolated were Staphylococcaceae (48.27%), Enterobacteriaceae (14.94%), and Streptococcaceae (6.89%). The antibiogram profiles of bacterial cultures revealed a 57.1% resistance to levofloxacin and a 53.3% resistance to penicillin in Staphylococcus lugdunensis, whereas Staphylococcus aureus showed a 76.9% resistance to penicillin and a 58.3% resistance to fusidic acid. High resistance rates of 63.5% for tigecycline, 63.3% for ampicillin, and 40.5% for colistin were observed for Gram-negative isolates. Resistances of 62.5%, 61.5%, and 53.8% to erythromycin, clindamycin, and penicillin, respectively, were observed in the anaerobes. Conclusions: Patients with HS displayed considerable resistance to bacterial proliferation. The revised therapeutic guidelines for HS should incorporate the latest insights into bacterial antibiotic resistance.
RESUMEN
Background/Objectives:Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CoNS) commonly found on human skin. Unlike other CoNS, S. lugdunensis has a notable potential to cause severe infections comparable to Staphylococcus aureus. This study aimed to characterize the clinical and microbiological profile of patients with S. lugdunensis skin infections at a single center. Methods: We conducted a retrospective analysis of patient records from the Dermatology Department of the University Hospital of Heraklion, Greece, covering the period from January 2014 to January 2024. Patients' clinical presentations, demographics, infection sites, comorbidities, prior infections, antimicrobial treatments, and therapeutic responses were examined. Specimens were collected, transported, and processed according to standardized microbiological protocols. Bacterial identification and antibiotic susceptibility testing were performed using the Vitek 2 automated system and MALDI-TOF MS, with results interpreted according to Clinical and Laboratory Standards Institute (CLSI) criteria. Results: A total of 123 skin specimens positive for S. lugdunensis were analyzed. The cohort comprised 62 males (50.4%) and 61 females (49.6%), with a mean age of 40.24 ± 20.14 years. Most specimens were collected from pus (84%), primarily from below the waist (66.7%). Hidradenitis suppurativa (26%) was the most common condition associated with S. lugdunensis, followed by folliculitis, abscesses, ulcers, cellulitis, and acne. Co-infections with other bacteria were noted in 49.6% of cases, and 25.2% of infections were nosocomially acquired. The majority of patients (65%) received systemic antibiotics, predominantly amoxicillin/clavulanic acid, cefuroxime axetil, and doxycycline, with a cure rate of 100%. All isolates were susceptible to several antibiotics, though resistance to penicillin (28.5%) and clindamycin (36%) was observed. Conclusions:S. lugdunensis is a significant pathogen in skin infections, capable of causing severe disease. The high cure rate demonstrates the effectiveness of appropriate antibiotic therapy. Continued monitoring and antimicrobial stewardship are essential to manage resistance and ensure effective treatment.
RESUMEN
Hidradenitis suppurativa (HS) has been linked with body image (BI) impairment and reduced quality of life (QoL). We sought to evaluate the associations between Cutaneous Body Image Scale (CBIS) and disease severity in HS patients.Between July 2020 and January 2022, a cross-sectional study was carried out including consecutive HS patients above the age of 16 who attended a Tertiary Referral Hospital in Greece. Disease Severity was graded with the Hurley stage, HS-Physician's Global Assessment (HS-PGA) scale, and the Modified Sartorius scale (MSS). Patients completed at their first visit ten survey instruments including Patients' Severity of disease, pain and pruritus scale, CBIS, Multidimensional Body-Self Relations Questionnaire (MBSRQ) including 5 subscales: Appearance Evaluation (AE), Appearance Orientation (AO), Body Areas Satisfaction Scale (BASS), Overweight Preoccupation (OWP), and Self Classified Weight (SCW) , Dermatology Quality of Life Index (DLQI), Skindex-16, EQ5D 5L, EQ- visual analogue scale (VAS), PHQ9, and GAD7. In total, 70 HS patients above 16 years old participated, mean [SD] age, 34.44 [11.64] years; 49/70 (70%) males and 21/70 (30%) females. Mean ± SD CBI, DLQI, Skindex-16 total, EQ-5D-5L, EQ VAS, PHQ9 and GAD7 were 5.59 ± 1.58, 11.70 ± 8.88, 52.90 ± 27.75, 0.75 ± 0.21, 62.48 ± 21.12, 7.64 ± 5.56, 7.87 ± 5.23 respectively. Moderate to severe CBI dissatisfaction was reported by 36/70 (51.42%) patients. CBI was correlated with appearance evaluation (AE) (p < 0.01, r = 0.544), body areas satisfaction (BASS) (p < 0.01, r = 0.481), and overweight preoccupation subscale (OWPS) (p < 0.01, r = - 0.267), and Skindex-16 (p < 0.01, r = - 0.288). HS patients with affected genital areas scored higher in disease patient's severity score (p = 0.015), and male patients scored higher in Skindex-16 than females(p < 0.01). Our study found that the mean of CBI in HS patients was 5.59 ± SD 1.58. Predictors for CBI dissatisfaction were low scores of MBSRQ Appearance Evaluation (AE) and Body Areas Satisfaction Subscale (BASS).
