RESUMEN
OBJECTIVES: Two bolt-on dimensions (skin irritation, self-confidence) have been developed for the EQ-5D-5L to improve its content validity and responsiveness in psoriasis. However, the two bolt-ons are not strictly psoriasis-specific and are potentially relevant in other skin conditions. This study aims to explore the content validity of the EQ-5D-5L with two bolt-ons in patients with atopic dermatitis (AD). METHODS: In 2021-2022, qualitative, semi-structured interviews were conducted with 20 adult AD patients at a university dermatology clinic in Hungary. We aimed for a heterogeneous sample in terms of age, gender, education and disease severity. Patients completed the EQ-5D-5L with two bolt-ons using a think-aloud protocol. Probing questions were posed to investigate item relevance, potential conceptual overlaps, missing concepts and the appropriateness of the recall period. Interview transcripts were subjected to thematic analysis. RESULTS: The EQ-5D-5L with the two bolt-ons covered the most important aspects of health-related quality of life in AD patients. Most patients found both the skin irritation and self-confidence bolt-ons relevant. Fifteen potential missing concepts were identified, but only two (social relationships, judgement by others) were identified by more than one patient. A smaller conceptual overlap was found between the skin irritation and pain/discomfort dimensions in 7 patients (35%). Half the patients expressed a preference for a recall period of 1 week rather than of 'today'. CONCLUSIONS: The EQ-5D-5L with skin irritation and self-confidence bolt-ons showed good relevance, comprehensiveness and comprehensibility in patients with AD. However, in terms of comprehensiveness, social relationships and judgement by others (stigma) may be missing from the questionnaire.

Despite the abundance of data on the COVID-19 vaccine-induced immune activation, the impact of natural autoantibodies (nAAbs) on these processes is less well defined. Therefore, we investigated potential connections between vaccine efficacy and nAAb levels. We were also interested in the impact of immunomodulatory therapies on vaccine efficacy. Clinical residual samples were used for the assessment of the COVID-19 vaccine-elicited immune response (IR) (n=255), as well as for the investigation of the immunization-associated expansion of the nAAb pool (n=185). In order to study the potential interaction between immunomodulatory therapies and the vaccine-induced IR, untreated, healthy individuals and patients receiving anti-TNFα or anti-IL-17 therapies were compared (n total =45). In-house ELISAs (anticitrate synthase, anti-HSP60 and-70) and commercial ELISAs (anti-SARS-CoV-2 ELISAs IgG, IgA, NeutraLISA and IFN-γ release assay 'IGRA') were applied. We found significant differences in the IR given to different vaccines. Moreover, nAAb levels showed plasticity in response to anti-COVID-19 immunization. We conclude that our findings may support the theorem about the non-specific beneficial 'side effects' of vaccination, including the broadening of the nAAb repertoire. Considering immunomodulation, we suggest that anti-TNFα and anti-IL17 treatments may interfere negatively with MALT-associated IR, manifested as decreased IgA titers; however, the modest sample numbers of the herein presented model might be a limiting factor of reaching a more comprehensive conclusion.

BACKGROUND: Hidradenitis suppurativa (HS) is a, chronic skin disease affecting up to 1% of the population in Europe. This study aims to assess the cost-of-illness of HS from a societal perspective in Hungary and to analyze the predictors of costs. METHODS: A multicentre, cross-sectional cost-of-illness study was performed among 200 adult HS patients. We evaluated direct medical (physician consultations, inpatient admissions, medical, and surgeries), direct non-medical (transportation and caregiving), and indirect costs (productivity loss). RESULTS: The mean annual cost-of-illness of HS was 6,791 per patient. The main cost components were productivity loss (53.3%), biological treatment (21.5%), and informal care (9.2%). Patients missed, on average, 26 and 63 days from work annually due to absenteeism and presenteeism, respectively. Male sex, more severe disease, gluteal involvement, and coexisting inflammatory bowel disease were associated with higher direct medical costs, while lower education level and worse quality-of-life outcomes predicted higher indirect costs. CONCLUSION: This is the first study to assess both direct and indirect costs in HS patients. HS imposes a substantial burden on patients and society, predominantly arising from productivity loss and biological therapy. Resource utilization data and cost-of-illness estimates provide valuable inputs into cost-effectiveness analyses of health interventions in HS.

Bullous pemphigoid (BP) is an autoimmune blistering disease of elderly patients that has shown increasing incidence in the last decades. Higher prevalence of BP may be due to more frequent use of provoking agents, such as antidiabetic dipeptidyl peptidase-4 inhibitor (DPP4i) drugs. Our aim was to assess DPP4i-induced bullous pemphigoid among our BP patients and characterize the clinical, laboratory and histological features of this drug-induced disease form. In our patient cohort, out of 127 BP patients (79 females (62.2%), 48 males (37.7%)), 14 (9 females and 5 males) were treated with DPP4i at the time of BP diagnosis. The Bullous Pemphigoid Disease Area Index (BPDAI) urticaria/erythema score was significantly lower, and the BPDAI damage score was significantly higher in DPP4i-BP patients compared to the nonDPP4i group. Both the mean absolute eosinophil number and the mean periblister eosinophil number was significantly lower in DPP4i-BP patients than in nonDPP4i cases (317.7 ± 0.204 vs. 894.0 ± 1.171 cells/µL, p < 0.0001; 6.75 ± 1.72 vs. 19.09 ± 3.1, p = 0.0012, respectively). Our results provide further evidence that DPP4i-associated BP differs significantly from classical BP, and presents with less distributed skin symptoms, mild erythema, normal or slightly elevated peripheral eosinophil count, and lower titers of BP180 autoantibodies. To our knowledge, this is the first case series of DPP4i-related BP with a non-inflammatory phenotype in European patients.
RESUMEN
PURPOSE: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects up to 1% of the population in Europe. The EQ-5D is the most commonly used generic instrument for measuring health-related quality of life among HS patients. This study aims to compare the measurement properties of the two adult versions of EQ-5D (EQ-5D-3L and EQ-5D-5L) in patients with HS. METHODS: We recruited 200 consecutive patients with HS (mean age 37 years, 38% severe or very severe HS) to participate in a multicentre cross-sectional survey. Patients completed the EQ-5D-3L, EQ-5D-5L, Dermatology Life Quality Index (DLQI) and Skindex-16 questionnaires. RESULTS: More than twice as many different health state profiles occurred in the EQ-5D-5L compared to the EQ-5D-3L (101 vs. 43). A significant reduction in ceiling effect was found for the mobility, self-care and usual activities dimensions. A good agreement was established between the EQ-5D-3L and EQ-5D-5L with an intraclass correlation coefficient of 0.872 (95% CI 0.830-0.903; p < 0.001) that was confirmed by a Bland-Altman plot. EQ-5D-5L improved both the absolute and relative informativity in all dimensions except for anxiety/depression. EQ-5D-3L and EQ-5D-5L demonstrated similar convergent validity with DLQI and Skindex-16. EQ-5D-5L was able to better discriminate between known groups of patients based on the number of comorbidities and disease severity (HS-Physician's Global Assessment). CONCLUSION: In patients with HS, the EQ-5D-5L outperformed the EQ-5D-3L in feasibility, ceiling effects, informativity and known-groups validity for many important clinical characteristics. We recommend using the EQ-5D-5L in HS patients across various settings, including clinical care, research and economic evaluations.

Psoriasis is a systemic inflammatory skin disorder that can be associated with sleep disturbance and negatively influence the daily rhythm. The link between the pathomechanism of psoriasis and the circadian rhythm has been suggested by several previous studies. However, there are insufficient data on altered clock mechanisms in psoriasis to prove these theories. Therefore, we investigated the expression of the core clock genes in human psoriatic lesional and non-lesional skin and in human adult low calcium temperature (HaCaT) keratinocytes after stimulation with pro-inflammatory cytokines. Furthermore, we examined the clock proteins in skin biopsies from psoriatic patients by immunohistochemistry. We found that the clock gene transcripts were elevated in psoriatic lesions, especially in non-lesional psoriatic areas, except for rev-erbα, which was consistently downregulated in the psoriatic samples. In addition, the REV-ERBα protein showed a different epidermal distribution in non-lesional skin than in healthy skin. In cytokine-treated HaCaT cells, changes in the amplitude of the bmal1, cry1, rev-erbα and per1 mRNA oscillation were observed, especially after TNFα stimulation. In conclusion, in our study a perturbation of clock gene transcripts was observed in uninvolved and lesional psoriatic areas compared to healthy skin. These alterations may serve as therapeutic targets and facilitate the development of chronotherapeutic strategies in the future.

BACKGROUND: Pemphigus is a chronic autoimmune blistering disease of the skin and mucosa severely impairing patients' health-related quality of life (HRQoL). To date, no studies have measured subjective well-being in terms of life satisfaction in pemphigus. Our main objective was to evaluate satisfaction with life in patients with pemphigus, and to analyse its relationship with clinical severity and HRQoL. METHODS: A cross-sectional survey was carried out enrolling 77 patients with pemphigus. Subjective well-being was measured using the Satisfaction with Life Scale (SWLS). HRQoL was assessed by the Dermatology Life Quality Index (DLQI) and EQ-5D-5L. Disease severity was measured by Autoimmune Bullous Skin Disorder Intensity Score (ABSIS). RESULTS: Mean ABSIS, DLQI, EQ-5D-5L and SWLS scores of patients were 11.7 (SD 17.3), 5.4 (6.8), 0.84 (0.22) and 4.76 (SD 1.52), respectively. The proportion of patients indicating extreme dissatisfaction, dissatisfaction, slightly below average in life satisfaction, average satisfaction, high satisfaction and very high satisfaction with life was 6 (7.8%), 5 (6.5%), 14 (18.2%), 16 (20.8%), 21 (27.3%) and 15 (19.5%), respectively. Life satisfaction was independent from age, gender, level of education and type of disease. A path analysis revealed that there was no direct relationship between ABSIS and SWLS (beta = - 0.09; p = 0.428); however, the following indirect path was confirmed: ABSIS â DLQI â EQ-5D-5L â SWLS. CONCLUSIONS: Disease severity and HRQoL measures regularly used to assess patients' health status may be complemented with a measure of subjective well-being, such as SWLS, to achieve a more holistic assessment of patients' lives and optimise pemphigus care.

BACKGROUND: Chronic spontaneous urticaria (CSU) is defined as symptoms of urticaria persisting for 6 weeks or more without obvious cause. Autologous serum skin test (ASST) positivity in patients with CSU is considered to be associated with autoimmune urticaria (AIU). METHODS: In this retrospective study we retrieved the medical records of 1,073 urticaria patients seen at the Department of Dermatology and Allergology of Szeged University between January 2005 and February 2014. Forty-two patients (36 female and 6 male) met the study criteria by having CSU and giving positive results in the ASST. Our aim was to assess the clinical efficacy and safety of low-dose oral prednisolone therapy administered to patients with antihistamine-refractory ASST-positive CSU for a few months. Patients were given an initial dose (40 mg/day) of prednisolone until the complete resolution of the symptoms, usually 7-10 days, and then the dose was gradually decreased, as in other autoimmune diseases. RESULTS: Prednisolone therapy lasted for an average of 3.6 months and a complete long-lasting response was achieved in 35 of 42 AIU patients (83.3%). The follow-up period was at least 36 months (3 years) for each AIU patient; the longest follow-up time was 139 months (11.5 years). None of the patients reported any considerable side effects. CONCLUSION: Based on our results, we suggest that the use of this treatment could be an alternative for the treatment of AIU. Our present results also highlight the need for other therapies in a small percentage of AIU patients. Our results suggest that AIU represents a transient autoimmunity that can be successfully treated with low-dose steroid therapy administered for a few months.

BACKGROUND: It hasn't been clearly understood yet whether sensitization to antibiotics, the virus itself or transient loss of drug tolerance due to the virus, is responsible for the development of maculopapular exanthems following amoxicillin intake in patients with infectious mononucleosis. We aimed to examine whether sensitization to penicillin developed among patients with skin rash following amoxicillin treatment within infectious mononucleosis. METHODS: Ten patients were investigated for drug sensitization by lymphocyte transformation test and six patients were further tested by prick-, intradermal and patch tests employing the penicillin's main antigens. RESULTS: Lymphocyte transformation test showed negative results with amoxicillin, while one patient had positive reaction to cefixime. Six patients with suspected sensitization to amoxicillin were then investigated by in vivo tests. Prick tests were negative in all six patients, but the intradermal tests showed positive reactions in four patients. CONCLUSIONS: Our data demonstrate that in vitro testing is not sensitive enough in determining drug sensitization to penicillin. In vivo tests should be performed to detect sensitization and indeed with skin tests our results confirmed that sensitization to aminopenicillin may develop within infectious mononucleosis.
RESUMEN
Ulcus vulvae acutum Lipschütz or acute genital ulcer is a distinct clinical entity characterized by sudden painful genital ulceration occurring mostly in young and virgin girls with malaise, fever and other systemic symptoms. This distressing syndrome is rare and may be presented to dermatologists, gynecologists or pediatricians. Its diagnosis and therapy can be challenging. We present two young female patients with ulcus vulvae acutum. The cause of the disease could not be confirmed in our patients, but, interestingly, both patients had partial IgA deficiency. In the last 100 years, after its first description by Lipschütz, many case reports and series have aimed to identify a specific cause of the disease, without success. These studies mainly focused on infectious agents as causative factors, however, in most cases connection with infection could not be confirmed. Our opinion is that the decreased level of IgA could be a possible explanation for the cause of this syndrome. With our cases we would like to emphasize the possible role of local immunological mechanisms rather than several infectious agents in the development of this little-known disease.

Christ-Siemens-Touraine syndrome (CST; OMIM 305100) belongs to the group of ectodermal dysplasias and is characterized by the development of sparse hair, abnormal or missing teeth and sweating deficiency. CST is the consequence of mutations located in the ectodysplasin A (EDA1) gene. We have identified a 35-year-old Hungarian man with characteristic dysmorphic facial features, sparse hair, reduced sweating and missing teeth. Direct sequencing of the coding regions revealed a novel missense mutation in the eighth exon (c.971T/A, p.Val324Glu). The affected patient carries the mutation in a hemizygous form. Previous studies reported the association of missense mutations with non-syndromic tooth agenesis. However, the reported hemizygous patient exhibits hypodontia as well as hypotrichosis and reduced sweating. His daughter, an obligate heterozygous carrier of the identified missense mutation, exhibits only mild teeth abnormalities. As the novel missense mutation is located within the tumor necrosis factor (TNF) domain of the ectodysplasin protein, we hypothesize that this genetic variant affects the ectodysplasin/NFκB signaling pathway.

Brooke-Spiegler syndrome (BSS; OMIM 605041) is an autosomal dominant disease characterized by skin appendage tumors due to mutations in the cylindromatosis gene (CYLD). We investigated a Hungarian BSS pedigree with two affected members, father and daughter. Direct sequencing demonstrated a novel missense mutation (c.2613C>G; p.His871Gln) in exon 19 within the ubiquitin-specific protease domain of the encoded protein. We performed preliminary analysis to reveal the functional role of this novel mutation. Our data suggest that this novel CYLD mutation leads to increased ubiquitination of NEMO through influencing deubiquitinating activity of the CYLD protein and thus may result in enhanced NF-κB signalling.

Marie Unna Hereditary Hypotrichosis 1 (MUHH1; OMIM 146550), a rare monogenic condition characterized by the development of sparse, twisted hair or complete hair loss, is the consequence of mutations located in the hairless (HR) gene. We have identified a 68-year-old Hungarian woman affected by alopecia universalis and limb deformities of all four extremities. Direct sequencing of the coding regions of the HR gene revealed a novel missense mutation in the third exon of the HR gene (c.974G/A, p.Gly325Asp). The affected family member carried the mutation in a heterozygous form, while the only available, clinically unaffected family member (the son of the patient) and the unrelated controls carried the wild type sequence. The association between the presence of HR gene mutations and the development of alopecia is well-established, however, further studies are needed to elucidate the putative role of this novel HR mutation in the development of limb deformities.

Gorlin-Goltz syndrome is a rare multisystemic disease, characterized by numerous basal cell carcinomas. The ideal approach for patients with the syndrome would be a treatment with a high cure rate, minimal scarring, short healing time and mild side-effects. Electrochemo-therapy is a novel therapeutic option that ablates tumours with electrical current and simultaneously administered anticancer drugs. Three patients with Gorlin-Goltz syndrome were treated with electrochemotherapy using intravenous bleomycin. Clinical response was obtained in 98 (99%) of the lesions, 86 (87%) of them showed complete response. In 2 tumours, regression was confirmed with histological examination. Long-term cosmetic results were excellent. We consider electrochemotherapy to be an additional tool in the therapeutic armamentarium for Gorlin-Goltz syndrome, and suggest using it as early as possible in selected patients to avoid disfiguring scarring.

UNLABELLED: Allopurinol is an effective urate lowering drug, which is usually well-tolerated with no adverse effects in most cases, but about 2% of the treated patients develop a skin rash, and patients may experience severe allopurinol-induced hypersensitivity syndrome. AIMS: The aim of the authors was to summarize and present the clinical manifestations of allopurinol-induced hypersensitivity in patients treated at the Department of Dermatology and Allergology, University of Szeged in order to identify potential associations with this syndrome. METHODS: Retrospective review of all patients who were referred to the department with allopurinol-induced hypersensitivity syndrome in the last four years. RESULTS: During four years, 11 patients were treated with allopurinol-induced hypersensitivity syndrome. The average age was 70.3 years. Before the initiation of allopurinol therapy, 36% of patients had already suffered from various degrees of renal impairment, and 72% of them had been taking thiazide diuretics. Cutaneous manifestations were mainly generalized, erythematous, maculopapular exanthemas (9 patients, 82%), and two patients showed signs of erythema multiforme (18%). Asymptomatic hyperuricemia was the indication for allopurinol therapy in all patients. CONCLUSIONS: Allopurinol-induced hypersensitivity syndrome is a severe, life-threatening disease. Administration of allopurinol should be initiated with clear indications in appropriate dose. Old age, underlying renal impairment and concomitant thiazide diuretic intake should be considered as potential risk factors for developing hypersensitivity syndrome.
