Real-world effectiveness and safety of bimekizumab for hidradenitis suppurativa: An ambispective observational study.

In this original research, we present the results in terms of effectiveness and safety of bimekizumab for hidradenitis suppurativa in real clinical practice. Results indicated significant improvement in all activity scores and patient-reported outcomes at week 16, including a notable decrease in mean IHS4 from 27.1 to 15.6 (p < 0.001), HS-PGA from 5.1 to 3.2 (p < 0.001), VAS pain from 8.3 to 4.7 (p < 0.001) and DLQI from 21.6 to 12.6 (p < 0.001). Bimekizumab, administered every 2 or 4 weeks, was well-tolerated with no discontinuations and no new safety concerns identified. These findings corroborate the drug's effectiveness and favourable safety profile observed in phase 3 clinical trials, supporting its use in real-world clinical practice for treating HS.

Insights into the Window of Opportunity and Outcome Measures in Patients with Moderate to Severe Hidradenitis Suppurativa Treated with Secukinumab: A Real-World Study.

INTRODUCION: The concept of a window of opportunity in hidradenitis suppurativa (HS) management suggests that early initiation of biological therapy leads to better outcomes, though its timing remains uncertain. METHODS: We conducted a retrospective observational multicenter study, including consecutive patients with moderate to severe HS who initiated secukinumab treatment following prior failure with systemic antibiotics or adalimumab. Therapeutic burden was defined as the sum of previous systemic treatment cycles and previous major surgical interventions for HS. Patients were followed up for 24 weeks. Main outcomes were safety and effectiveness, assessed through the proportion of patients achieving HS Clinical Response (HiSCR) and a 55% reduction in International HS Severity Score System (IHS4-55). Additionally, potential predictors of response to secukinumab were studied. Analysis was performed on an intention-to-treat basis. RESULTS: A total of 67 patients (33 men, 34 women) were included, with a mean age of 41.55 (11.94) years and a mean baseline IHS4 of 17.88 (11.13). The mean therapeutic burden was 6.06 (3.49). At week 24, 10.45% (7/67) of patients experienced adverse events, with three leading to treatment discontinuation. At week 24, 41.79% (28/67) of patients achieved HiSCR, and 44.78% (30/67) of patients achieved IHS4-55. HiSCR could not be calculated in 12 patients with a baseline AN count < 3. A lower therapeutic burden was significantly associated with a higher likelihood of achieving HiSCR and IHS4-55 at week 24. CONCLUSIONS: Secukinumab showed safety and efficacy in real-world patients with HS, and the inverse correlation found between therapeutic burden and treatment response supports the concept of a window of opportunity, offering insights into its timing.

Safety and Effectiveness of Percutaneous Ultrasound-Guided Galvanic Current in Tunnels of Patients with Hidradenitis Suppurativa: A Pilot Study.

INTRODUCTION: The recurrent nature of hidradenitis suppurativa (HS), even under maintained systemic treatment, makes it necessary to have effective local treatments; however, the response to these therapies is variable (44-81%). The application of galvanic current (GC) has demonstrated its utility in humans in treating lesions structurally similar to those of HS. With this background, the main objective of this study was to evaluate the efficacy and safety of ultrasound-guided percutaneous GC in inflamed and/or draining tunnels of HS. METHODS: This was an open study (one-way repeated measures design over time). Patients were evaluated at 4 and 12 weeks after receiving GC. A combined clinical response at week 12 (absence of suppuration/inflammation on examination and clinical interview) was considered the principal variable of efficacy. Adverse effects potentially associated with GC were reported by telephone and at each visit. RESULTS: Twenty-six patients were included, with a male/female ratio of 5:8. The mean age was 35.84 (13.14) years. At 12 weeks after the administration of GC, a complete response was achieved in 77% (20/26) of the treated lesions. No serious adverse effects were observed, and the mean procedural pain assessed by the numeric rating scale was 0.03 (0.2). CONCLUSION: GC has proven to be effective and well tolerated in inflamed and draining tunnels of patients with HS.

Stratum Corneum Hydration As a Potential Marker of Response to Dupilumab in Atopic Dermatitis: A Prospective Observational Study.

Background: Dupilumab is an effective treatment for atopic dermatitis (AD) and it also restores skin barrier function. Nevertheless, early changes in epidermal barrier parameters related to sustained treatment response or treatment failure are not known. So, the objective of this study is to evaluate whether changes in skin barrier function after 16 weeks dupilumab treatment could predict sustained treatment response or treatment failure. Materials and Methods: A prospective observational study was conducted that included patients with AD starting dupilumab. Clinical scores, patient-reported outcome measures (PROMs), and skin barrier function parameters were assessed at baseline and after 16 weeks treatment. Patients were followed until they failed to dupilumab or until the end of the study period. Participants were divided into 2 groups: patients with treatment failure and those with sustained treatment response. Results: In total, 32 patients with AD were included in the study, with a mean age of 28.03 years (standard deviation 10.65), being 20 (60.6%) females. In total, 22 (66.7%) patients sustained dupilumab response during the study period and only 10 (33.3%) failed to treatment. After 16 weeks treatment, clinical scores were improved in both groups. Patients with sustained treatment response increased stratum corneum hydration (SCH) on noninvolved skin (34.25 arbitrary units [AU] vs 44.90AU, P = 0.001) and on eczematous lesions (20.71 AU vs 40.94 AU, P < 0.001) and also decreased transepidermal water loss (TEWL) on eczematous lesions (28.22 g/[m2·h] vs 14.83 g/[m2·h], P = 0.002). Patients with treatment failure did not change TEWL or SCH. SCH after 16 weeks treatment on noninvolved skin (odds ratio [OR] = 0.83, P = 0.018) and SCH after 16 weeks treatment on eczematous lesions (OR = 0.86, P = 0.028) were related to dupilumab failure. Conclusion: SCH could be used as a predictive biomarker of dupilumab response in patients with AD.

Short-Term Effectiveness, Safety, and Potential Predictors of Response of Secukinumab in Patients with Severe Hidradenitis Suppurativa Refractory to Biologic Therapy: A Multicenter Observational Retrospective Study.

INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease. Biologic drugs have a key role in the long-term anti-inflammatory treatment of moderate to severe patients due to their immunomodulatory properties. The aim of this study is to evaluate the effectiveness and safety of secukinumab in patients with moderate to severe HS after 16 weeks of treatment, and to explore potential predictors of clinical response to the drug. METHODS: Multicenter observational retrospective study. Patients treated with secukinumab 300 mg every 2 or 4 weeks who had completed at least 16 weeks of follow-up from nine hospitals based in southern Spain (Andalusia) were included in this study. Treatment effectiveness was assessed using the Hidradenitis Suppurativa Clinical Response (HiSCR). Information about adverse events was collected, the therapeutic burden of the patients was calculated as the summation of systemic medical treatments and surgical interventions (excluding incision and drainage) experienced until the start of secukinumab treatment. RESULTS: Forty-seven patients with severe HS were included for analysis. At week 16, 48.9% (23/47) of patients achieved HiSCR. Adverse events were present in 6.4% (3/47) of the patients. The multivariate analysis showed that female sex and, to a lesser extent, lower body mass index (BMI) and a lower therapeutic burden were potentially associated with a higher probability of HiSCR achievement. CONCLUSIONS: Favorable short-term effectiveness and safety of secukinumab in the treatment of severe HS patients were observed. Female sex, lower BMI and a lower therapeutic burden may be associated with a higher probability of achieving HiSCR.

Potential Predictors of Cardiovascular Risk Improvement in Patients with Hidradenitis Suppurativa Treated with Adalimumab: A Pivotal Study of Factors Associated with Carotid Intima-Media Thickness Reduction.

INTRODUCTION: Hidradenitis suppurativa (HS) has been linked to higher cardiovascular risk (CVR) due to its inflammatory burden. There is little evidence on how biologic treatment could modify the cardiovascular risk of patients with HS. The aims of the present study were to explore the modification of CVR in patients under adalimumab treatment and to explore the potential factors associated with CVR improvement. METHODS: A prospective longitudinal study was performed. A cohort of patients with HS treated with adalimumab was followed up. Carotid intima-media thickness (IMT) and other clinical and biochemical CVR factors were collected at baseline and 32 weeks after starting the treatment. RESULTS: Twenty-seven patients with severe HS were included. Overall, there were no differences in IMT between baseline (633 µm) and 32 weeks follow-up (634 µm). However, 40.7% (11/27) of the patients presented an improvement in IMT. This group (IMT responders) had a higher prevalence of dyslipidemia, diabetes mellitus, higher HbA1c levels, consumed more tobacco, and had higher BMI at baseline. Moreover, these patients had lower IHS4 scores at baseline and tended to have a greater IMT basal value, indicating a higher burden of subclinical atherosclerosis. CONCLUSIONS: Adalimumab treatment might benefit a subset of patients with HS in terms of cardiovascular risk reduction. In light of the results of the present study patients with classical cardiovascular risk factors, and those with higher burden of subclinical atherosclerosis and with less inflammatory load, may be more likely to improve their IMT during adalimumab treatment.

External Validation of the IHS4-55 in a European Antibiotic-Treated Hidradenitis Suppurativa Cohort.

BACKGROUND: Previously, a new dichotomous outcome was developed, calculated as 55% reduction in the International Hidradenitis Suppurativa 4 (IHS4-55) score. It was validated in datasets of adalimumab and placebo-treated HS patients. External validation is an important aspect of clinical outcomes. OBJECTIVES: We aimed to externally validate the novel dichotomous IHS4-55 in a non-biologic treated dataset of HS patients. METHODS: Data from a previously published European-wide prospective clinical study of antibiotic treatment of HS patients were used to assess the association of IHS4-55 achievement with individual reduction in inflammatory nodules, abscesses, and draining tunnels. Moreover, the associations between IHS4-55 positivity and achievement of the minimal clinically important differences (MCIDs) for Dermatology Life Quality Index (DLQI), Numerical Rating Scale (NRS) Pain, and NRS Pruritus were analyzed. RESULTS: Data were obtained from 283 individual patients, of which 36.4% (103/283) were treated with clindamycin and rifampicin and 63.6% (180/283) with tetracyclines for 12 weeks. Achievers of the IHS4-55 demonstrated a significant reduction the counts of inflammatory nodules, abscesses, and draining tunnels (all p < 0.001). Additionally, IHS4-55 achievers had an odds ratio for achieving the MCID of DLQI, NRS Pain, and NRS Pruritus of 2.16 (95% CI 1.28-3.65, p < 0.01), 1.79 (95% CI 1.10-2.91, p < 0.05), and 1.95 (95% CI 1.18-3.22, p < 0.01), respectively. CONCLUSIONS: This study shows the external validity of the novel IHS4-55 by demonstrating a significant association between IHS4-55 achievement and a reduction in inflammatory lesion counts as well as achievement of MCIDs for DLQI, NRS Pain, and NRS Pruritus in an antibiotic-treated cohort. These findings support the use of the IHS4-55 as a novel primary outcome measure in clinical trials.

Patterns of Surgical Recurrence in Patients with Hidradenitis Suppurativa.

BACKGROUND: Surgery is an essential part of hidradenitis suppurativa (HS) treatment. Understanding and reducing surgical recurrence are crucial to obtaining the best results in patients' treatment. OBJECTIVE: The aim of the study was to characterize surgical recurrences in a cohort of patients with HS treated with wide excision and second-intention healing. METHODS: A prospective nested case-control study was conducted. A cohort of patients with HS treated with wide excision and second-intention healing was monitored for 68 weeks. The surgical procedure was classified as case (recurrence) or control (no recurrence). The type of recurrence was classified according to the elementary lesion in tunnel or abscess and inflammatory nodule (AN) recurrence. Sociodemographic and clinical data likely related to recurrence and the type of recurrence were evaluated. RESULTS: Sixty-three patients were included, receiving a total of 82 surgical procedures. The mean age of the patients was 36.18 years, and the surgical site presented a Hurley stage II severity in 79.26% (65/82) of the interventions. Tunnel recurrence was observed in 8.5% (7/82) and AN recurrence in 15.85% (13/82) of the interventions. Obesity was associated with a higher risk of recurrence, for both tunnel and AN recurrence. Hurley III at the surgical site, a history of pilonidal sinus, and higher International Hidradenitis Suppurativa Severity Score System (IHS4) after surgery and at week 68 increased the risk of tunnel recurrence. CONCLUSION: We propose classifying surgical recurrence based on the elemental type of lesion. Tunnel recurrence could originate in the depth of the surgical scar and could be associated with both surgical site factors and inflammatory load. AN recurrence could originate in the borders of the surgical scar and may particularly benefit from preoperative ultrasound.

Prevalence and implications of type D personality in patients with alopecia areata: A marker of quality-of-life impairment and mood status disturbances, a comparative study.

INTRODUCTION: Distressed personality (or Type D personality, TDp) is a personality trait that has been associated with poor quality of life in patients suffering from a variety of skin diseases such as psoriasis or urticaria. To date the potential association between Alopecia areata (AA) and TDp has not been studied. The aim of this study was to compare the prevalence of TDp between patients with AA and controls, and to analyse the impact of TDp on patients with AA regarding mood status disturbances, quality of life and sexuality. METHODS: Cross-sectional study includes patients suffering from mild-to-severe AA and sex- and age-matched healthy controls. Socio-demographic and clinical variables, quality of life, sexual disfunction, anxiety, depression and TDp were collected using validated questionnaires. RESULTS: A total of 120 participants (60 patients and 60 controls) were included. Patients with AA showed higher prevalence of TDp than controls (35% vs. 15% p = 0.01), as well as higher rates of anxiety, depression and sexual dysfunction (p < 0.05). TDp was found to be linked to disease severity (p = 0.04), anxiety and depression scores (p < 0.001) and worse quality of life (p = 0.001). No relationship was found between TDp and sexual dysfunction. DISCUSSION: Type D personality prevalence is higher in patients with AA than in controls. It is associated with higher rates of anxiety, depression and worse quality of life. Screening for this type of personality could be useful to detect patients who could benefit from additional psychological support as a complement to their medical treatment.

Exploring the role of systemic immune-inflammation index and neutrophil-lymphocyte ratio in cardiovascular risk stratification for patients with hidradenitis suppurativa: A cross-sectional study.

Hidradenitis suppurativa (HS) is a chronic inflammatory disease of the hair follicle that has previously been associated with a higher cardiovascular risk (CVR). Although different methods have been described for CVR stratification in HS, there is little evidence about the role of hemogram indexes in CVR in HS. Given its potential convenience, the aim of this study was to assess the role of the hemogram indexes systemic immune-inflammation index (SII) and neutrophil-lymphocyte ratio (NLR) in CVR stratification for patients with HS. A cross-sectional study was performed to assess the role of SII and NLR in CVR stratification in patients with moderate to severe HS who were candidates for biologic therapy. SII, NLR, carotid intima-media thickness, and other clinical and biochemical CVR factors were assessed before the start of the treatment. Fifty patients were included. The male:female ratio was 3:2, and the mean International Hidradenitis Suppurativa Severity Score System score was 21.6. After multivariate analysis, SII correlated with higher values of systolic blood pressure, metabolic syndrome, and higher risk of insulin resistance (p < 0.05). NLR was associated with insulin resistance (p < 0.05). These associations were independent of age, sex, body mass index, severity of the disease, and tobacco consumption. The implementation of SII and NLR in daily practice may be of benefit for identifying patients with HS at higher risk of high blood pressure, insulin resistance, or metabolic syndrome. Since these indexes are simple to calculate, they could be used as a screening tool in HS-specific units.

Impact of the COVID-19 Pandemic on the Diagnosis and Prognosis of Melanoma.

Background: Early detection of melanoma is one of the main diagnostic goals of dermatologists worldwide, due to the increasing incidence of the disease in our environment. However, the irruption of the SARS-CoV-2 pandemic has posed a challenge to global healthcare, forcing systems to focus their resources on the fight against COVID-19. Methods: Retrospective cohort study. The exposed cohort were patients diagnosed with melanoma in the year after the general confinement in Spain (15 March 2020) and the unexposed cohort were patients with melanoma diagnosed in the previous year. Results: 130 patients were included. No differences were observed between demographic characteristics in both cohorts. The mean Breslow of melanoma before the onset of the pandemic was 1.08, increasing to 2.65 in the year after the onset of the pandemic (p < 0.001). On the other hand, the percentage of melanomas in situ decreased from 38.96% to 16.98% in the year after the declaration of the state of alarm in Spain. Conclusions: The SARS-CoV-2 outbreak has led to a reduction in the early diagnosis of melanoma, with an increase in invasive melanomas with poor prognosis histological factors. This could lead to an increase in melanoma-related mortality in the coming years in our environment.

Intralesional Treatments in Hidradenitis Suppurativa: A Systematic Review.

Hidradenitis suppurativa (HS) is an inflammatory chronic disease with difficult management. In some scenarios, intralesional (IL) treatments could be useful. However, the scientific evidence available is limited and heterogeneous. We aimed to synthesize the available scientific evidence on IL treatments in HS. We conducted a systematic review in July 2021. The clinical databases reviewed included MEDLINE and Embase. All types of epidemiological studies and case series with at least 10 patients were included; reviews, guidelines, protocols, conference abstracts, case series with less than 10 patients, and case reports were excluded. Fifteen articles representing 599 patients and 1,032 lesions were included for review. Corticosteroid injections were the most reported treatment. They showed effectiveness for the treatment of acute inflammatory lesions and fistulas in terms of reduction of lesion counts, symptoms, and signs of inflammation and were safe in general terms. Light-based therapies were the other main treatment group, including photodynamic therapy and 1,064-nm diode laser. They were also effective, but more local and systemic adverse events were reported. Other treatments included botulinum toxin type B and punch-trocar-assisted cryoinsufflation (cryopunch). They were effective and safe, although were reported anecdotally. The main limitation of the systematic review was the general quality of the articles included. In conclusion, IL treatments such as corticosteroid injections and light-based therapies seem to be effective and safe for both acute inflammatory lesions and fistulas, although more prospective studies, with higher sample sizes and with standardized outcomes are needed to provide more scientific evidence on the subject.

Switching from Adalimumab Originator to Biosimilar: Clinical Experience in Patients with Hidradenitis Suppurativa.

Adalimumab is currently the only biological medicine approved by the FDA for the treatment of hidradenitis suppurativa (HS). The breakout of biosimilar drugs made them more accessible due to their impact on pharmacoeconomics. However, packaging, formulation, or excipients are unique characteristics of each drug. In that way, switching from adalimumab originator to biosimilar and between biosimilars could have implications in the clinical practice. The objective of this study is to describe our clinical experience in switching from adalimumab originator to biosimilar and switching back again. A single-center retrospective cohort study was conducted that included seventeen patients with HS treated with adalimumab originator in the maintenance phase, and that achieved Hidradenitis Suppurativa Clinical Response (HiSCR), who were switched to adalimumab biosimilar for no medical reasons. The reason for the change was to improve pharmacoeconomic efficiency, following our hospital policies on biologics. Median duration with adalimumab originator treatment before switching was 48 weeks. After switching, 41.2% of patients maintained HiSCR response without additional issues, while 58.8% (10/17) reported problems after the change. Switching from adalimumab originator to biosimilar in well-controlled patients could imply problems in efficacy and adherence. Switching back to adalimumab originator appears to solve most of the problems, but some patients can lose confidence in the drug and discontinue it. It would be worthwhile to evaluate the benefit-risk ratio individually when switching an HS patient to adalimumab biosimilar.

Epidermal Barrier Function and Skin Homeostasis in Atopic Dermatitis: The Impact of Age.

Skin is damaged in atopic dermatitis (AD) patients. Age is also believed to have a negative effect on epidermal barrier function. The aim of this study was to investigate skin barrier function changes with age in AD patients. A cross-sectional study was conducted including 162 participants, 81 AD patients and 81 healthy volunteers. Skin barrier function parameters, such as transepidermal water loss (TEWL), erythema, temperature, stratum corneum hydration (SCH), pH, and elasticity, were evaluated. Healthy volunteers were evaluated on the volar forearm. AD patients were measured on two regions: on an eczematous lesion on the volar forearm and on a non-involved area 5 cm from the affected area. TEWL was lower on healthy skin than uninvolved AD skin (9.98 vs. 25.51 g·m-2·h-1, p < 0.001) and AD eczematous lesions (9.98 vs. 28.38 g·m-2·h-1, p < 0.001). SCH was lower on AD eczematous lesions than uninvolved AD skin (24.23 vs. 39.36 AU, p < 0.001) and healthy skin (24.23 vs. 44.36 AU, p < 0.001). Elasticity was lower on AD eczematous lesions than uninvolved AD skin (0.69 vs. 0.74, p = 0.038) and healthy skin (0.69 vs. 0.77, p = 0.014). A negative correlation was found between age and elasticity in all the population (r = -0.383, p < 0.001). This correlation was stronger in AD patients (r = -0.494, p < 0.001) than in controls (r = -0.266, p = 0.092). After conducting a linear regression model in AD patients adjusted by age, sex, and SCORing Atopic Dermatitis (SCORAD), it was found that elasticity was impaired by an increasing age (ß = -0.004, p < 0.001) and a higher SCORAD (ß = -0.003, p < 0.001). The skin barrier function is impaired by age and AD, reflected mainly in poor elasticity values in older AD patients.

Combined versus conventional photodynamic therapy with 5-aminolaevulinic acid nanoemulsion (BF-200 ALA) for actinic keratosis: A randomized, single-blind, prospective study.

BACKGROUND: Photodynamic therapy (PDT) has become one of the most effective therapies for the treatment of actinic keratosis, allowing the removal of more than one lesion in a single session. However, the pain sustained by the patient during treatment and local skin reactions can limit its use. OBJECTIVES: To determine the efficacy and safety of combined PDT (daylight PDT followed by conventional PDT) vs conventional PDT 12 weeks after treatment. METHODS: The study was performed as a randomized, single-center, non-inferiority clinical trial with two parallel groups. A total of 51 patients with grade I and II AKs on the scalp or face were randomized. Twenty-five patients received one session of combined PDT (combPDT), and 26 patients received one session of conventional PDT (cPDT). The primary endpoint was the reduction of AKs, 12 weeks after treatment. The secondary endpoint was the reduction in pain and local skin reaction. RESULTS: The reduction rate of grade I and II AKs was similar in combPDT and cPDT, showing no statistically significant differences between both groups, 76.67% vs 86.63% [P = .094] and 80.48% vs 83.08% [P = .679], respectively. However, pain was significantly lower in the combPDT group (2.56 vs 5, P < .01), as were local skin reactions. CONCLUSIONS: CombPDT has proven to be as effective as cPDT for the treatment of grade I and II AKs located on the scalp and face. Furthermore, combPDT has been shown to be considerably more tolerable than cPDT, causing only mild local skin reactions.

Assessment of hand hygiene strategies on skin barrier function during COVID-19 pandemic: A randomized clinical trial.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) has increased the frequency of handwashing. There is scarce evidence regarding the impact of different hand hygiene procedures on skin barrier function in clinical practice. OBJECTIVE: To compare the impact on skin barrier function of different hand hygiene measures in healthcare workers in daily practice. METHODS: A randomized controlled clinical trial was conducted. Participants were randomized to sanitize their hands with water and soap, alcohol-based hand sanitizers (ABHSs), or disinfectant wipes during their 8-hour working shift. Epidermal barrier functional parameters, such as transepidermal water loss (TEWL), and the microbial load were assessed before and immediately after the working day. Tolerance and acceptability of each product were recorded after work. RESULTS: Sixty-two participants were included and 20, 21, and 21 were randomized to use water and soap, ABHS, and disinfectant wipes, respectively. After the 8-hour shift, TEWL increase was higher with disinfectant wipes than with soaps or ABHS (+5.45 vs +3.87 vs -1.46 g h-1  m-2 , respectively; P = .023). Bacteria and fungi colony-forming unit (CFU) count reductions were lower for the water and soap group than for ABHS and disinfectant wipes. Disinfectant wipes were considered more difficult to use (P = .013) compared with water and soap and ABHS. CONCLUSION: Daily hand hygiene with ABHS showed the lowest rates of skin barrier disruption and the highest reduction of CFU.

Sexual Dysfunction and Quality of Life in Patients with Hidradenitis Suppurativa and Their Partners.

Hidradenitis suppurativa (HS) is a chronic skin disease that profoundly affects patients' quality of life (QoL) and sexuality. Few data are available on the impact of HS on patients' partners. We aimed to explore the QoL and sexual function of patients' partners and the factors associated with their impairment and to compare the QoL and sexual function of single patients and those in a stable relationship. We conducted a cross-sectional study at Hospital Universitario Virgen de las Nieves (Granada, Spain) and at the Wroclaw Medical University (Wroclaw, Poland). Patients over the age of 16 years attending their scheduled follow-up and their partners, if any, were included. The Dermatology Life Quality Index (DLQI) and the Family Dermatology Life Quality Index (FDLQI) were used to estimate the QoL of patients and partners, respectively. The FSFI-6 was used to determine sexual dysfunction in women and the IIEF-5 for erectile dysfunction in men. Thirty-four single patients and twenty-eight patients in a stable relationship and their partners were included. Patients had a very large impact (DLQI 12.5 ± 7.5) and their partners a moderate impact (FDLQI 10.3 ± 7.1) in their QoL due to HS. Women with HS had a high prevalence of sexual dysfunction (13/32, 40.6%) and men of erectile dysfunction (19/30, 63.3%). Male partners also had a high prevalence of erectile dysfunction (10/17, 58.8%), while only one female partner had sexual dysfunction (1/11, 9.1%). Factors related to disease severity, intensity of symptoms and body mass index were associated with poorer QoL in partners and time of disease evolution with greater erectile dysfunction in male partners. In conclusion, HS not only profoundly affects the QoL and sexuality of patients but also of their partners. Several risk factors have been identified, which should be taken into account in the holistic approach of the disease.

The Role of Oral Contraceptive Pills in Hidradenitis Suppurativa: A Cohort Study.

There is a need to establish the role of antiandrogens as an alternative or concomitant therapy for hidradenitis suppurativa (HS). Thus, the objectives of this study are (1) to assess the effectiveness of oral contraceptive pills (OCPs) at week 12 in HS women, and (2) to describe the clinical profile of patients receiving oral contraceptive pills (OCPs). A prospective observational study was designed. This study included 100 participants, 50 women with HS who started OCPs for the first time at our HS Clinic and 50 participants without OCP treatment. The main outcome of interest was the percentage of reduction in total abscess and inflammatory nodule (AN) count at week 12. Thirty-three women received combined OCPs and 17 non-combined OCP. HS patients with OCPs treatment were younger (31.7 vs. 40.9 years, p < 0.001), thinner (28.62 vs. 33.35 kg/m2), and have a higher number of areas affected (2.32 vs. 1.38, p = 0.02) than those without OCPs. After 12-weeks of treatment, it was observed that the percentage of AN reduction was higher in HS women receiving OCP than in patients without OCP (53.9% vs. 38.42%, p = 0.049). It was observed that OCP prescription (ß = 3.79, p = 0.034) and concomitant therapy (ß = 3.91, p = 0.037) were independently associated with a higher % AN when controlling for disease duration, concomitant therapy, and treatment with/without OCP (R2 = 0.67). The factors potentially associated with the percentage AN reduction at week 12 in HS women treated with OCPs were disease duration (ß = -1.327, p = 0.052), concomitant therapy (ß = 11.04, p = 0.079), and HS worsening with the menstrual cycle (ß = 10.55, p = 0.087). In conclusion, OCPs might be effective for improving AN count in women with HS. Women whose HS worsens in relation to the menstrual cycle and have a shorter disease may benefit more from the therapeutic effect of OCPs.

Familial Frontal Fibrosing Alopecia: Report of a case and systematic review of the literature.

Frontal fibrosing alopecia (FFA) is an emerging disease in Western countries. We present the cases of three sisters who were referred simultaneously to the Department of Dermatology, Hospital Universitario San Cecilio, Granada, Spain, in 2018. All patients suffered from at least partial frontotemporal hairline recession and eyebrow loss. Following trichoscopic examination, the three sisters were diagnosed with FFA. Only one of the sisters agreed to be treated; she was prescribed with topical clobetasol propionate solution and minoxidil and achieved disease control at the three-month follow-up. These patients represent a new case of familial FFA wherein three sisters as well as their mother were affected by FFA. A systematic review found a total of 24 cases of familial FFA, of which this report is the 25th. In the majority of families, only females were affected (88%) while in the remainder both males and females (8%) were affected; there was only one family where only males were affected (4%). The relationship between the affected individuals was predominately between sisters (56%) followed by mother and daughter (32%). The median age was 61 years old (range: 14-88 years) and the duration of the disease ranged between 3-360 months. Family groups of FFA are an infrequently described phenomenon with unknown prevalence.
