RESUMO

Introduction: Our previous study showed that the severity of atopic dermatitis (AD) in children significantly correlates with the quality of life and perceived stress in their mothers. Aim: To compare strategies for coping with stress in mothers of children with and without AD, as well as to investigate the relationship between coping strategies of mothers of affected children and AD variables, stress intensity, and quality of life. Material and methods: The study included 88 mothers of children with AD and 57 mothers of children without AD as controls. The severity of skin lesions in children with AD was assessed by the Scoring Atopic Dermatitis (SCORAD) index, and skin itch was evaluated by the Numerical Rating Scale (NRS). All mothers completed the sociodemographic questionnaire (SD), the Perceived Stress Scale (PSS), and the Coping Orientations to Problems Experienced (COPE) scale. Additionally, mothers of children with AD filled out the Family Dermatology Life Quality Index (FDLQI). Results: There were no statistically significant differences in coping strategies between the groups. However, there were significant correlations between the selected coping strategies and AD severity, perceived stress of mothers, and quality of life of the entire family of affected children. Conclusions: Although mothers of children with AD experience higher levels of stress compared with mothers of children without AD, the disease does not change coping strategies. Psychological support for mothers of children with AD should be oriented toward strengthening cognitive coping strategies.

RESUMO

BACKGROUND: Generalized pustular psoriasis (GPP) is a systemic inflammatory disease that can be severe, debilitating and life threatening. Uncontrolled activation of interleukin (IL)-36 proinflammatory activity may underlie the pathogenesis of GPP. Currently, GPP-specific treatment options are limited. OBJECTIVES: To evaluate the efficacy and safety of the anti-IL-36 receptor antibody imsidolimab in patients with GPP. METHODS: In an open-label, single-arm, multiple-dose study, patients with GPP were treated with imsidolimab to assess clinical efficacy, tolerability and safety. Patients received an intravenous dose of imsidolimab 750 mg on day 1, followed by three subcutaneous doses of imsidolimab 100 mg administered on days 29, 57 and 85. The primary efficacy endpoint was the proportion of patients who achieved a clinical response at weeks 4 and 16 following treatment with imsidolimab, as measured by the Clinical Global Impression scale. RESULTS: Eight patients were enrolled and six completed the study. Responses were observed as early as day 3, most rapidly for pustulation relative to other manifestations of GPP, with continued and consistent improvement across multiple efficacy assessments at day 8, day 29 and through day 113. Most treatment-emergent adverse events (TEAEs) were mild to moderate in severity. No patient discontinued the study owing to a nonserious TEAE. Two patients experienced serious adverse events (SAEs); no deaths were reported. CONCLUSIONS: Imsidolimab demonstrated a rapid and sustained resolution of symptoms and pustular eruptions in patients with GPP. It was generally well tolerated, with an acceptable safety profile, and is advancing to phase III trials. These data support the targeting of IL-36 signalling with a specific antibody - imsidolimab - as a therapeutic option for this severely debilitating condition.

RESUMO

Atopic dermatitis is a chronic inflammatory skin disease significantly affecting patients' and their parents' lives. Mothers are mostly responsible for the long-term treatment and their wellbeing is essential. The major objective of this cross-sectional study was to investigate the relationship between atopic dermatitis in children, especially concomitant itch, and the quality of life, stress, sleep quality, anxiety, and depression of their mothers. The study included 88 mothers of children with atopic dermatitis and 52 mothers of children without atopic dermatitis. All mothers completed sociodemographic questionnaire, the Perceived Stress Scale, the Athens Insomnia Scale and the Hospital Anxiety and Depression Scale. Additionally, mothers of children with atopic dermatitis filled in the Family Dermatology Life Quality Index. The severity of atopic dermatitis and pruritus intensity were evaluated by the Scoring Atopic Dermatitis Index and the Numerical Rating Scale, respectively. The severity of atopic dermatitis and itch significantly correlated with the quality of life, insomnia, and perceived stress of the mothers. Mothers whose children had had atopic dermatitis for more than 6 months had significantly higher scores of anxiety and depression. The results highlight the importance of screening mothers for functional impairment to provide adequate support. More attention should be directed to the standardization of stepped care interventions addressing factors resulting in the impaired functioning of mothers.

RESUMO

Introduction: Chronic venous insufficiency (CVI) is a widespread and serious social problem. The pathogenesis of the disease is multifactorial and one of the important factors in its development is inflammation. Aim: Assessment of the concentration of selected acute phase proteins: C-reactive protein (CRP) and α1 antitrypsin (AAT) in the blood serum of patients with CVI before and after treatment with Sulodexide. Material and methods: The study was carried out in 88 people, including 39 clinically healthy subjects as the reference group and 49 patients with CVI at various stages of the disease. The concentrations of CRP and AAT were determined. Results: The concentration of CRP in patients before the use of Sulodexide, compared to the results in the reference group, was statistically significantly higher. The concentration decreased significantly after the applied treatment. AAT concentration was significantly (p < 0.05) higher in the group of patients compared to the reference group. After treatment with Sulodexide, AAT concentration decreased in all study groups, which was statistically significant compared to the reference group. Conclusions: Elevated levels of acute phase proteins: CRP and AAT in patients indicate the participation of the inflammatory component in the pathogenesis of CVI. Monitoring levels of acute phase protein, especially AAT, may be useful in tracking the course of the disease, the body's response to treatment, and in making prognosis. Sulodexide, which acts mainly as an anticoagulant and profibrinolytic, also has an anti-inflammatory effect, which may contribute to the inhibition of the development of subsequent stages of CVI.

RESUMO

Introduction: Alopecia areata (AA) and vitiligo are both skin diseases of autoimmune origin. AA is characterized by patchy hair loss primarily on the scalp but may involve other areas as well, while vitiligo is caused by the destruction of melanocytes and results in the appearance of white patches on any part of the body. Many facts indicate similar pathogenesis of these diseases. Both dermatoses are associated with frequent coexistence of other autoimmune diseases and share common genetic risk factors. Recent data support the theory of the involvement of IL-17 in the pathogenesis of both AA and vitiligo. Aim: To evaluate and compare the serum levels of interleukin (IL)-17 in patients with AA and non-segmental vitiligo (NSV). To assess whether the pattern of serum cytokine concentration can be associated with clinical details and activity of the disease. Material and methods: A cross-sectional study was conducted on 33 patients with AA, 30 patients with NSV, and 30 healthy controls. Serum levels of IL-17 were determined quantitatively by ELISA method. Results: Our analysis identified a systemic inflammatory signature associated with AA and NSV, characterized by elevated levels of IL-17. The levels of IL-17 did not differ significantly between AA patients and NSV patients. Conclusions: Our results show that AA and vitiligo may share common etiopathogenetic pathways, which suggests the potential of developing targeted therapies for both AA and vitiligo treatment. Imbalance of T cell subpopulations and complex systemic cytokine profiles may contribute to the pathogenesis of AA and vitiligo.

RESUMO

A cyclic tetrapeptide Pro-Pro-Pheß3ho-Phe (4B8M) was tested for immunosuppressive activity and potential therapeutic utility in several in vitro and in vivo mouse and human models. The tetrapeptide was less toxic for mouse splenocytes in comparison to cyclosporine A (CsA) and a parent cyclolinopeptide (CLA). The tetrapeptide demonstrated potent anti-inflammatory properties in antigen-specific skin inflammatory reactions to oxazolone and toluene diisocyanate as well to nonspecific irritants such as salicylic acid. It also inhibited inflammatory processes in an air pouch induced by carrageenan. In addition, 4B8M proved effective in amelioration of animal models corresponding to human diseases, such as nonspecific colon inflammation induced by dextran sulfate and allergic pleurisy induced by ovalbumin (OVA) in sensitized mice. The tetrapeptide lowered expression of EP1 and EP3 but not EP2 and EP4 prostaglandin E2 (PGE2) receptors on lipopolysaccharide-stimulated Jurkat T cells and ICAM-1 expression on human peripheral blood mononuclear cells (PBMC). Its anti-inflammatory property in the carrageenan reaction was blocked by EP3 and EP4 antagonists. In addition, 4B8M induced an intracellular level of PGE2 in a human KERTr keratinocyte cell line. In conclusion, 4B8M is a low toxic and effective inhibitor of inflammatory disorders with potential therapeutic use, affecting the metabolism of prostanoid family molecules.

RESUMO

Alopecia areata (AA) and vitiligo are both common skin diseases of autoimmune origin. Both alopecia areata and vitiligo have shown to be affected by oxidative stress. The present work is aimed at evaluating and comparing the serum proinflammatory cytokine levels in AA and nonsegmental vitiligo (NSV). A cross-sectional study was conducted of 33 patients with AA, 30 patients with NSV, and 30 healthy controls. Serum levels of interferon γ (IFN-γ), interleukin- (IL-) 1ß, and IL-6 were determined quantitatively by ELISA method. Our analysis identified a signature of oxidative stress associated with AA and NSV, characterized by elevated levels of IFN-γ (AA: p = 0.007283; NSV: p = 0.038467), IL-1ß (AA; NSV: p ≤ 0.001), and IL-6 (AA; NSV: p ≤ 0.001). IL-6 was also significantly increased in NSV patients in comparison with AA patients (p = 0.004485). Our results supported the hypothesis that oxidative stress may play a significant role in promoting and amplifying the inflammatory process both in AA and vitiligo. The complex understanding of both disease etiopathogenesis involves interrelationships between oxidative stress and autoimmunity. The clinical study registration number is RNN/266/16/KE.

RESUMO

The treatment goal in atopic dermatitis is eliminating clinical symptoms of the disease, preventing exacerbations and complications, as well as improving patients' quality of life. In cases of severe atopic dermatitis and lack of response it is recommended to introduce systemic therapy. Patients ofter require multi-specialist consultations, and occasionally hospitalization. It is not recommended to use acupuncture, acupressure, bioresonance, homeopathy, or Chinese herbs in the treatment of atopic dermatitis.

RESUMO

Atopic dermatitis is a chronic and recurrent inflammatory dermatosis with concomitant intensive pruritus, and is diagnosed both in children and adults. Atopic dermatitis-patients are predisposed to have bacterial, viral and fungal skin infections; they also suffer from an increased risk of developing food allergies (especially, at an infantile age), allergic rhinitis, or bronchial asthma (a so-called atopic march). Currently, an increasing atopic dermatitis incidence constitutes a serious medical problem that regards not only dermatology and allergology, but also paediatrics, and family medicine. The basis for atopic dermatitis treatment and prophylaxis is restoration of epidermal barrier functions by means of tailored emollients. Atopic dermatitis therapies should effectively eliminate clinical symptoms of the disease, prevent exacerbations as well as complications, and improve patients' quality of life.

RESUMO

INTRODUCTION: Psoriasis is considered as a risk factor for atherosclerosis and contributes to myocardial infarction, ischemic heart disease and brain stroke. AIM: To estimate the atherogenic potential of psoriasis by analysing antioxidative and prooxidative factors (paraoxonase-1, α-tocopherol, uric acid, homocysteine), compare levels of these parameters between groups of psoriatic patients and healthy individuals as well as to analyse the impact of psoriasis severity and duration on the factors under the study and to define correlation between the marked factors and patients' lifestyles, body mass index (BMI) and abdominal circumference. MATERIAL AND METHODS: The investigated group consisted of 66 patients with psoriasis vulgaris, while the control group comprised 30 persons. Both groups were comparable as regards their age, sex and BMI as well as abdominal circumference. RESULTS: A significantly lower activity of paraoxonase-1 (p < 0.001), level of tocopherol (p < 0.05) and significantly higher concentration of homocysteine (p < 0.01), uric acid (p < 0.05) were found in patients with psoriasis as compared to the reference group. A higher homocysteine level occurs in patients with a negative family history of psoriasis (p < 0.05). In the group of patients with psoriasis and metabolic syndrome, the uric acid level was significantly higher (p < 0.05). Concentration of uric acid correlated negatively with the abdominal circumference value (p < 0.001). CONCLUSIONS: Psoriasis promotes arteriosclerosis development by decreasing the levels of antiatherogenic and increasing the levels of proatherogenic agents. Adverse changes in psoriatic patients involve activity of paraoxonase-1, levels of α-tocopherol, uric acid, homocysteine as compared to healthy individuals selected by their age, BMI and abdominal circumference value.

RESUMO

The article presents the results of clinical trials of wound dressings whose main ingredient is butyric-acetic chitin copolyester (BAC 90:10). It is a chitin derivative soluble in typical organic solvents. During the trial, the dressings were used on wounds resulting from venous insufficiency or diabetes. The trial evaluated the safety of use and efficacy of three forms of the dressing including porous membrane (Medisorb R Membrane), porous membrane with silver (Medisorb R Ag), and powder (Medisorb R Powder). The clinical trial had a multi-centre character. Three medical units were engaged in the study. The trial included 36 patients (12 men and 24 women). The mean age of the participants was 65 years of age (age range: 26-96). The choice of dressings was made on the basis of preliminary evaluation of the wound, clinical signs of infection, or risk of infection. Medisorb R Membrane dressing was used in 23 patients, Medisorb R Ag dressing was used in 15 patients, and Medisorb R powder was used in two patients. During the course of the trial, there were 10 control visits planned. The obtained results prove the safety and efficacy of dressings in question. The efficacy of treatment was evaluated as good. In the majority of patients, the ulceration was decreased both on the surface and in depth. The success of the treatment relied not only on the applied dressing, but also the stage of the basic disease, the accompanying diseases, and the age of the patient.

RESUMO

AIM OF THE STUDY: Ongoing national screening programmes suggest that the prevalence of chronic hepatitis C (CHC) in Poland ranges between 0.5% and 1%. It has been recently noted that patients with confirmed coronary artery disease may be at higher risk for hepatitis C virus (HCV) infection. MATERIAL AND METHODS: Testing for the presence of anti-HCV antibodies was performed in a group of patients admitted to the Cardiology Department with symptomatic ischemic heart disease (IHD) and in patients hospitalised in the Dermatology Department. RESULTS: A total of 1171 patients underwent anti-HCV testing: 672 patients in the Cardiology Department (K group) and 499 patients in the Dermatology Department (D group). Twenty-eight (2.4%) positive anti-HCV results were detected. The prevalence of positive anti-HCV antibodies in groups K and D was 2.23% and 2.61%, respectively (p > 0.05). Presence of HCV RNA was confirmed in 15 cases (1.28%) - 7 patients in group K and 8 patients in group D (1.04% and 1.6%, respectively; p > 0.05). CONCLUSIONS: Our findings suggest that this patient cohort has increased risk of HCV infection, which may influence screening strategies.

RESUMO

INTRODUCTION: To assess the efficacy and safety of the subcutaneous (s.c.) secukinumab 150 mg with loading (150 mg) or without loading (150 mg no-load) regimen through 104 weeks in patients with active psoriatic arthritis (PsA) in the FUTURE 4 (NCT02294227) study. METHODS: Patients with PsA (N = 341) were randomized to s.c. secukinumab 150 mg, 150 mg no-load or placebo at baseline, weeks 1, 2, 3 and every 4 weeks thereafter. All placebo patients were reassigned to secukinumab 150 mg no-load at either week 16 (non-responders) or week 24 (responders). The primary end point was ACR20 at week 16. Patients could have their dose escalated from 150 to 300 mg based on their physician's decision starting at week 36. Pre- and post-escalation ACR and PASI responses were also assessed. RESULTS: A total of 95.6% (326/341), 84.5% (288/341) and 79.8% (272/341) patients completed 16, 52 and 104 weeks of treatment, respectively. The primary end point was met; ACR20 response rate at week 16 was 41.2% and 39.8% with the 150 mg and 150 mg no-load groups, respectively, versus placebo (18.4%; adjusted P value = 0.0003 for both treatment arms). Efficacy responses observed at week 16 in both treatment regimens were sustained up to week 52 and 104, with many patients continuing to show improvements up to week 104. After dose escalation to 300 mg, the proportion of patients with non-/low-level ACR/PASI response decreased with increasing proportions of patients having higher ACR/PASI responses. No new or unexpected safety signals were reported. CONCLUSION: The secukinumab 150 mg or 150 mg no-load regimen demonstrated significant and sustained improvements in the signs and symptoms of psoriatic arthritis through 104 weeks; the loading regimen was associated with numerically higher and earlier responses for some high-hurdle end points. Improved efficacy was observed upon dose escalation from 150 to 300 mg. The safety profile was consistent with previous reports. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT02294227.

RESUMO

INTRODUCTION: Alopecia areata (AA) is considered an autoimmune disorder characterized by patchy loss of hair from the scalp and other body parts. Many patients develop the disease in childhood. AIM: To answer the question whether abnormal production of some proinflammatory cytokines (IL-2, IL-6, IL-15, IL-17A and IFNγ) in children with AA may facilitate the development or progression of the disease. MATERIAL AND METHODS: The study group consisted of 42 children with AA, the control group - 37 healthy children. Peripheral venous blood samples were collected from patients with AA and healthy controls and the concentrations of serum cytokines, namely IL-2, IL-6, IL-15, IL-17A, IFN-γ were determined quantitatively by ELISA method. RESULTS: The serum IL-6, IL-15, IL-17A and IFNγ levels were significantly increased in patients with AA compared with control subjects (p < 0.05). The serum IL-15 level was found to be increased when the total duration of AA was increased (q = 0.30; p = 0.05). The serum cytokine level of IL-17A was found to be decreased when duration of the current episode was longer than 2 years (p < 0.05), but the correlation between IL-17A serum level and duration of the current episode was not confirmed in the Spearman test (q = -0.06; p = 0.68). The serum IL-17A level was found to be significantly decreased when the thyroiditis was present (q = -2.378; p < 0.05). CONCLUSIONS: The increased levels of serum IL-6, IL-15, IL-17A and IFNγ in children suggest imbalance in the serum proinflammatory cytokines production in AA.

RESUMO

BACKGROUND: Tofacitinib is an oral Janus kinase inhibitor that is under investigation for the treatment of psoriatic arthritis. We evaluated tofacitinib in patients with active psoriatic arthritis who had previously had an inadequate response to tumor necrosis factor (TNF) inhibitors. METHODS: In this 6-month randomized, placebo-controlled, double-blind, phase 3 trial, we randomly assigned 395 patients, in a 2:2:1:1 ratio, to four regimens: 5 mg of tofacitinib administered orally twice daily (132 patients); 10 mg of tofacitinib twice daily (132 patients); placebo, with a switch to 5 mg of tofacitinib twice daily at 3 months (66 patients); or placebo, with a switch to 10 mg of tofacitinib twice daily at 3 months (65 patients). Data from the patients who received placebo during the first 3 months of the trial were pooled. The primary end points were the percentage of patients who had at least 20% improvement according to the criteria of the American College of Rheumatology (ACR20 response) and the change from baseline score on the Health Assessment Questionnaire-Disability Index (HAQ-DI; scores range from 0 to 3, with higher scores indicating greater disability) at the month 3 analysis. RESULTS: At 3 months, the rates of ACR20 response were 50% with the 5-mg dose of tofacitinib and 47% with the 10-mg dose, as compared with 24% with placebo (P<0.001 for both comparisons); the corresponding mean changes from baseline in HAQ-DI score were -0.39 and -0.35, as compared with -0.14 (P<0.001 for both comparisons). Serious adverse events occurred in 4% of the patients who received the 5-mg dose of tofacitinib continuously and in 6% who received the 10-mg dose continuously. Over the course of 6 months, there were four serious infections, three herpes zoster infections, one myocardial infarction, and one ischemic stroke among the patients who received tofacitinib continuously. Elevations of aspartate and alanine aminotransferase concentrations of three or more times the upper limit of the normal range occurred in more patients who received tofacitinib continuously than in patients who received placebo followed by tofacitinib. CONCLUSIONS: In this trial involving patients with active psoriatic arthritis who had had an inadequate response to TNF inhibitors, tofacitinib was more effective than placebo over 3 months in reducing disease activity. Adverse events were more frequent with tofacitinib than with placebo. (Funded by Pfizer; OPAL Beyond ClinicalTrials.gov number, NCT01882439 .).

RESUMO

OBJECTIVES: To confirm the association of previously discovered psoriasis (Ps) risk loci with the disease in a Polish population and to create predictive models based on the combination of these single nucleotide polymorphisms (SNPs). MATERIAL AND METHODS: Thirty-eight SNPs were genotyped in 480 Ps patients and 490 controls. Alleles distributions were compared between patients and controls, as well as between different Ps sub-phenotypes. The genetic risk score (GRS) was calculated to assess the cumulative risk conferred by multiple loci. RESULTS: We confirmed associations of several loci with Ps: HLA-C, REL, IL12B, TRIM39/RPP21, POU5F1, MICA. The analysis of ROC curves showed that GRS combining 16 SNPs at least nominally (uncorrected P<0.05) associated with Ps (GRS-N) had significantly better discriminative power than GRS combining SNPs associated with Ps after the Bonferroni correction (AUC 0.776 vs. 0.750, P = 1 x 10-4) or HLA-C (AUC 0.776 vs. 0.694, P<1 x 10-5). On the other hand, adding additional SNPs to the model did not improve its discriminatory ability (AUC 0.782 for GRS combining all SNPs, P>0.05). In order to assess the total risk conferred by GRS-N, we calculated ORs according to GRS-N quartile - the Ps OR for top vs. bottom GRS-N quartiles was 12.29 (P<1 x 10-6). The analysis of different Ps sub-phenotypes showed an association of GRS-N with age of onset and family history of Ps. CONCLUSIONS: We confirmed the association of Ps with several previously identified genetic risk factors in a Polish population. We found that a GRS combining 16 SNPs at least nominally associated with Ps had a significantly better discriminatory ability than HLA-C or GRS combining SNPs associated with Ps after the Bonferroni correction. In contrast, adding additional SNPs to GRS did not increase significantly the discriminative power.

RESUMO

BACKGROUND/OBJECTIVES: Emollients are part of the standard treatment for atopic dermatitis (AD), although there is limited evidence that regular use of emollients as management therapy reduces the frequency of flares and corticosteroid consumption. The objective of this study was to evaluate the benefit of emollient use in the management of mild to moderate AD in children by assessing the ability of two different emollients (particularly V0034CR) to prevent flares and to reduce the use of corticosteroids. METHODS: In this randomized, open-label study, patients with a current flare were treated with a potent topical corticosteroid. After flare resolution, patients were centrally randomized to V0034CR emollient, reference emollient, or no emollient (1:1:1 ratio) for 12 weeks. New flares were medically assessed before being treated with a moderately potent corticosteroid. RESULTS: A total of 335 children 2 to 6 years of age were randomized. At 12 weeks, the percentage of patients with one or more flares was statistically significantly lower with V0034CR (35.1%) than without emollient (67.6%; p < 0.001). Fewer patients treated with V0034CR required any corticosteroids or immunosuppressants (23.6%) than patients with no emollient (43.3%) at 12 weeks. The difference was significant at all time points (p = 0.002). Patients treated with emollients had a longer time to first flare, fewer flares, higher complete remission rates, less corticosteroid consumption, lower Investigator Global Assessment scores, and lower Scoring Atopic Dermatitis scores than those who were not. V0034CR was well tolerated, with no specific safety concerns. CONCLUSION: Regular emollient use in children with mild to moderate AD reduces flares and corticosteroid consumption.

RESUMO

BACKGROUND: Psoriasis vulgaris is characterized by disfiguring and stigmatizing skin lesions. The links among lesions distribution, severity, and stigmatization remain unclear. OBJECTIVE: We sought to investigate if the involvement of visible and sensitive areas is linked to stigmatization. METHODS: In all, 115 patients with psoriasis vulgaris were assessed for disease severity, skin lesions distribution, itch, and stigmatization using the Feelings of Stigmatization Questionnaire. Quality of life was assessed with the Dermatology Life Quality Index and the World Health Organization Quality of Life-BREF. RESULTS: The localization of psoriatic lesions on the back of hands was related to higher stigmatization levels (P = .011, total score of the Feelings of Stigmatization Questionnaire), but not the involvement of nails, the palms, the face, or the genital area nor overall disease severity. All patients reported some level of stigmatization, regardless of the localization of lesions and type of psoriasis. Higher levels of stigmatization characterized patients who claimed not to be able to hide their lesions by clothing (P = .025), women (P = .001), and the unemployed (P = .004). Stigmatization was the strongest predictor of quality of life impairment. LIMITATIONS: Only hospitalized patients were included. CONCLUSIONS: Psoriatic lesions on the back of hands are debilitating and warrant effective treatment. Special attention should be paid to female patients, who are more sensitive to stigmatization.
