RESUMEN

The immunological pathogenesis of atopic dermatitis (AD) and chronic spontaneous urticaria (CSU) has not been fully elucidated yet. The aim of our research was to assess the serum concentration of interleukin-5 receptor (IL-5R) in relation to the disease activity and pruritus intensity in adult patients with AD and CSU. This pilot study included 45 participants (15 patients with AD, 15 patients with CSU, and 15 healthy controls). Blood samples were taken to examine the serum levels of IL-5R using the enzyme-linked immunosorbent assay (ELISA) test. The Scoring Atopic Dermatitis (SCORAD) index, the Urticaria Activity Score (UAS7), and the Visual Analogue Scale (VAS) were used to assess the disease activity and the pruritus intensity, respectively. Obtained results revealed that the IL-5R concentration was significantly higher in patients with CSU than in patients with AD and in the controls (p = 0.038). There was a positive correlation between the IL-5R level and the SCORAD index in patients with AD (r = -0.9, p = 0.047), which was not found for the CSU activity by UAS7 and with the pruritus severity by VAS in both examined groups of patients. Our findings underscore higher serum levels of IL-5R among CSU and AD patients, which may highlight its functional role in the pathogenesis of these diseases. In contrast, IL-5R might not be fully useful in reflecting the severity of symptoms. Although our results are promising, this study should be conducted on a larger cohort of patients.

RESUMEN

Background: Atopic dermatitis (AD) is a chronic relapsing, pruritic, inflammatory skin disease. Assessing the characteristics and risk factors of severe AD is central to healthcare workers' understanding and subsequent education of patients for the most optimal outcomes. The clinical characteristics are known to vary depending on populations and regions. AD has been well-documented in the global North in mainly Caucasian populations, while very few studies have been conducted on African patients residing in Africa. This study assessed the clinical characteristics, severity, and sociodemographic factors of children with AD in Southern Ethiopia. Methods: A hospital-based cross-sectional study was conducted among 461 children and their caregivers in four randomly selected hospitals in Southern Ethiopia from October 2022 to September 2023. A systematic sampling technique was used to enroll study participants. Clinical profile and sociodemographic data were collected by trained data collectors. The Scoring Atopic Dermatitis (SCORAD) index tool was used. The descriptive analysis was performed to characterize study participants. Univariate and ordinary logistic regression were used to identify factors associated with the SCORAD index score. The OR with 95% was used to show the strength of association, and a p-value of <0.05 was used to declare the level of significance. Result: Out of 461 AD-diagnosed children, 212 (46%) were girls and 249 (54%) were boys. In the sample of pediatric patients, 149 (32.3%) exhibited mild AD, 231 (46.2%) presented with moderate, and 99 (21.5%) showed signs and symptoms of severe AD. All patients had itching. Dryness of skin, excoriation, and erythema, followed by lichenification, were the most observed signs. In the ordinary logistic regression model, age onset of the disease [AOR 95% CI 1.95 (1.3-2.94)], sex of caregiver or family [AOR 95% CI 0.61 (0.41-0.90)], family atopy history [AOR 95% CI 0.64 (0.44-0.93)], mother education status [95% CI 2.45 (1.1-5.47)], and use of herbal medication [AOR 95% CI 0.50 (0.33-0.79)] were significantly associated with the severity of AD. Conclusion: In this study, 68% of children were found to have moderate-to-severe AD. Early onset, maternal education, familial atopy history, sex of caregiver, and use of herbal medication were independent predictors of severe AD in children. We recommend further investigation into these variables for their potential to serve as markers to assess the severity of AD and improve the care and management of children with AD in Ethiopia.

RESUMEN

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease affecting up to 20% of the pediatric population associated with alteration of skin and gut microbiome. Probiotics have been proposed for AD treatment. The ProPAD study aimed to investigate the therapeutic effects of the probiotic Lacticaseibacillus rhamnosus GG (LGG) in children with AD. METHODS: In total, 100 AD patients aged 6-36 months were enrolled in a randomized, double-blind, controlled trial to receive placebo (Group A) or LGG (1 x 1010 CFU/daily) (Group B) for 12 weeks. The primary outcome was the evaluation of the efficacy of LGG supplementation on AD severity comparing the Scoring Atopic Dermatitis (SCORAD) index at baseline (T0) and at 12-week (T12). A reduction of ≥8.7 points on the SCORAD index was considered as minimum clinically important difference (MCID). The secondary outcomes were the SCORAD index evaluation at 4-week (T16) after the end of LGG treatment, number of days without rescue medications, changes in Infant Dermatitis Quality Of Life questionnaire (IDQOL), gut microbiome structure and function, and skin microbiome structure. RESULTS: The rate of subjects achieving MCID at T12 and at T16 was higher in Group B (p < .05), and remained higher at T16 (p < .05)The number of days without rescue medications was higher in Group B. IDQOL improved at T12 in the Group B (p < .05). A beneficial modulation of gut and skin microbiome was observed only in Group B patients. CONCLUSIONS: The probiotic LGG could be useful as adjunctive therapy in pediatric AD. The beneficial effects on disease severity and quality of life paralleled with a beneficial modulation of gut and skin microbiome.

RESUMEN

BACKGROUND: Behçet's disease (BD) is a chronic inflammatory systemic disease that affects multiple organs. The causes of BD are still unknown, but it is primarily characterized by autoimmune reaction in the blood vessels. Current research focuses on treatments that can reduce the non-typical inflammatory responses of BD. Nevertheless, studies on improving the inflammatory effect of BD using inflammation mechanisms are still insufficient. Therefore, we conducted the integrated treatments related to inflammation modulation and achieved alleviation of symptoms in BD mice. METHODS: To understand the complex etiology of BD and compare its management, the herpes simplex virus (HSV)-induced BD mouse model was used. In order to alleviate the inflammatory response in BD mice, Taraxaci Herba (TH, herbal medicine), R7050-a TNFα inhibitor, and a mixture of TH and R7050 were injected for 2 weeks repetitively. The SCORAD index was examined to evaluate the cutaneous inflammations. In addition, histological changes and inflammatory factors were analyzed. RESULTS: Repetitive injection of TH and/or R7050 reduced the symptoms of BD and significantly decreased IL-6, IL-1ß, and TNFα in blood sera. Moreover, this treatment reduced the ulcers and the deterioration of skin. CONCLUSIONS: The results of our study showed that the down-regulation of inflammatory factors is related to the control of immune responses in BD models, suggesting that a mixed drug treatment may be more effective in improving the condition of BD.

RESUMEN

Atopic dermatitis (AD) is a chronic relapsing eczematous skin disease, which primarily affects infants and young children. Due to the side effects of commonly used drugs for its treatment, the development of safer therapeutic strategies is needed. There are many reports on the topical use of marshmallow (Althaea officinalis) for a range of skin diseases in Persian medicine. The main aim of the present investigation was evaluating the efficacy of marshmallow in children with mild-to-moderate atopic dermatitis. Another aim of the study was screening the anti-allergic and anti-inflammatory potential of phytocomponents against target proteins, including TNF-alpha, IL6, and PDEs A, B, and D enzymes with PDB IDs: 2AZ5, 1P9M, 3I8V, 4KP6, and 1Y2K, respectively, along with their respective standard ligands using computational docking analysis. A pilot clinical trial was designed to investigate the safety and efficacy of Althaea officinalis in children with AD. The diagnosis of AD was made according to the criteria of Hanifin and Rajka. Children between 3 months and 12 years old were participated in this trial and randomly allocated into two parallel intervention and control groups. The intervention group used Althaea officinalis 1% ointment while the positive control group used Hydrocortisone 1% ointment twice a day for a week and after that, three times per week for a period of 3 weeks. The severity of AD was measured using the SCORAD score at the end of each assessment visits. A total number of 22 patients completed the study. A significant decrease of the SCORAD score was observed in both groups. At the end of the study, this score change, which indicates the improvement of the patients was significantly higher in the intervention group in comparison to the baseline (p-value = .015) and week 1 (p-value = .018). In the docking analysis of the study, 33 phytochemical compounds were identified, which were docked into the active site of IL6, TNF-alpha, and human PDE4 isoenzymes. Affinity toward the selected enzymes was significantly higher in glycosylated compounds. The results of this pilot study showed that the efficacy of Althaea officinalis 1% ointment in a decrease of disease severity is more than Hydrocortisone 1% in children with AD. However, further studies are needed to confirm this finding. Moreover, the docking analysis revealed that the inhibitory activity of compounds with free hydroxyl groups such as glycosylated compounds was better than others, probably due to the hydrogen bond interaction of hydroxyl groups of the ligands with the enzymes.

RESUMEN

BACKGROUND: Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder affecting a large number of people in the world. Atopic dermatitis (AD) is a common inflammatory skin condition characterized by relapsing eczematous lesions in a typical distribution. It was first described in 1933 but exists since antiquity. AIM AND OBJECTIVES: To determine the relationship between AD and IBS. MATERIALS AND METHODS: A total of 109 patients with AD and 100 healthy controls were included in the study. They were defined for diagnosis of IBS according to ROME-III diagnostic criteria. Supporting findings, Bristol stool scale, frequency of defecation and history of AD and IBS were also evaluated. AD severity was assessed using Severity Scoring of Atopic Dermatitis index. RESULTS: A total of 62 patients (56.9%) in the AD group and 28 patients (28%) in the control group were diagnosed with IBS (P<0.001). Supportive findings excluding abnormal stool frequency and passage of mucus were more frequent in AD patients. There was no significant relationship between disease severity according to SCORAD index and variables in AD patients. CONCLUSIONS: This is a rather uncultivated area in the field of AD. We observed that IBS was more common in AD group. Also, supporting findings like abnormal stool form, abdominal distension, feeling of incomplete evacuation, and straining were found more frequently in AD patients. These results may indicate the association between AD and IBS. In our opinion, patients with atopic dermatitis should be questioned in terms of IBS.

Evaluar la concentración sérica de prolactina en los pacientes con dermatitis atópica y su relación con gravedad de la enfermedad. Métodos. El estudio se llevó a cabo en 46 pacientes con dermatitis atópica y 100 controles sanos de entre 0,5 y 19,5 años. El diagnóstico de dermatitis atópica se basó en las manifestaciones clínicas y se documentó la gravedad de la enfermedad. Se tomaron muestras de sangre venosa para medir la concentración de prolactina. Resultados. La concentración de prolactina no difirió entre los pacientes con dermatitis atópica y los controles, y no se estableció una relación entre la gravedad de la dermatitis atópica y la concentración sérica de prolactina. La prolactina no participa en la patogenia de la dermatitis atópica. Se necesitan otros estudios con tamaños muestrales más grandes y la medición de la concentración de prolactina en la piel para comprender la función de la prolactina en la patogenia de la dermatitis atópica.


Background. Prolactin performs as a neuroendocrine modulator of skin epithelial cell proliferation and the skin immune system. Objective. The aim was to assess the serum prolactin levels in patients with atopic dermatitis and the relationship with disease severity. Methods. The study was performed on 46 patients with atopic dermatitis and 100 healthy controls aged between 0.5 years and 19.5 years. The diagnosis of atopic dermatitis was based on clinical findings and the severity of the disease was documented. Venous blood sampling was performed in order to measure prolactin levels. Results. Prolactin levels in atopic dermatitis were not different from controls and there was no relationship between the severity of atopic dermatitis and serum prolactin levels. Prolactin may not have a role in the pathogenesis of atopic dermatitis. Further studies with larger sample sizes and measurement of prolactin levels in the skin may help to understand the role of prolactin in the pathogenesis of atopic dermatitis.

RESUMEN

BACKGROUND: The efficacy of low-dose medicine (LDM) in childhood mild/moderate eczema is not known. We conducted a double-blind, two-stage, randomized, placebo-controlled clinical trial, lasting 23 months, to address this issue. METHOD: Eighty children with chronic mild/moderate eczema were randomly allocated to Group A (placebo) or Group B (treatment group; Galium-Heel®, a low-dose multicomponent medicine based upon natural substances; Guna-Interleukin 12 and Guna-Interferon-γ administered twice a day for six non-consecutive months for each stage). LDM is characterized by the use of biological molecules, such as cytokines, neuropeptides, growth factors, hormones at very low concentrations, which correspond to physiological levels within the human body. The dosage of the cytokines used in this trial (IFN-γ and IL-12) is 10 fg/ml. The SCORAD index was evaluated by the same operator: subjects with a SCORAD index below 20 were considered to have mild eczema (61/80; mean: 10.79), whereas a SCORAD index between 20-50 indicated moderate eczema (19/80; mean: 26.84). The data of 66/80 children were analyzed in stage 1 and those of 62/66 children in stage 2. The primary outcome measure was reduction of eczema severity assessed by the SCORAD index. Secondary outcomes were disease-free interval, and treatment safety and tolerability. RESULTS: The decrease in disease severity was greater in Group B than in Group A already in stage 1 (a decrease 63.9% versus 53.2%), but the difference was not significant (p = 0.16). Moreover, subjective symptoms (itching and sleep disturbances) initially decreased and then worsened in Group A, whereas itching decreased linearly and sleep disturbances decreased significantly (p=0.049) in Group B. CONCLUSIONS: Preliminary evidence suggests potential benefit, but further work is needed to validate this approach. TRIAL REGISTRATION: The trial was registered with EudraCT number 2010-018640-13 through the database of the National Clinical Trials Monitoring Centre Database (Osservatorio delle Sperimentazioni Cliniche, OsSC) of the Italian Medicines Agency.

RESUMEN

BACKGROUND: The atopic dermatitis (AD) can limit a patient's physical and psychosocial development as well as lower their overall quality of life (QOL), including sleep quality. OBJECTIVE: The purpose of this study was to evaluate the relationships between clinical disease severity, QOL and sleep quality in children and adults with AD. METHODS: The SCORing atopic dermatitis (SCORAD) was examined to evaluate the severity of AD in fifty adult AD patients and 50 children AD patients. A questionnaire based on the children's sleep habits questionnaire (CSHQ) and the children's dermatology life quality index (CDLQI) were used to evaluate QOL and sleep disturbance in children AD patients. The Pittsburgh sleep quality index (PSQI) and dermatology life quality index (DLQI) were used in adult AD patients. RESULTS: The SCORAD and CSHQ score, the SCORAD and CDLQI score and the CSHQ and CDLQI score demonstrated significant correlations. The SCORAD and PSQI score showed no significant correlation. However, there were significant correlations between the SCORAD and DLQI score and the PSQI and DLQI score. CONCLUSION: Increasing severity of AD affects sleep quality in child AD patients. In adults, even though the total score of the sleep questionnaire is not associated with the severity of AD, two components of sleep questionnaire are associated with the severity of AD. There is a significant correlation between sleep quality and QOL in both children and adults. Therefore, we suggest that evaluating the sleep quality as well as clinical severity of the disease is necessary in the management of AD patients.

RESUMEN

OBJECTIVES: Despite the evidence supporting the use of vitamin D supplements for managing atopic dermatitis (AD), no meta-analysis providing definite conclusions in this field has been reported. The purpose of the present study was to conduct a systematic review and meta-analysis of all controlled studies of vitamin D for treating AD to elucidate the efficacy of vitamin D for alleviating the symptoms of AD. METHODS: Literature searches were conducted using Ovid-MEDLINE, EMBASE, Web of Science, Cochrane Library, and Korean and Chinese databases. Search terms used were "vitamin D", "atopic dermatitis", "randomized", "controlled trial", and "clinical trial". Random effects models were used to calculate the mean difference, with 95% confidence intervals to analyze the effects of vitamin D supplementation for severity of AD. RESULTS: Initial searches yielded 266 citations. Of these original results, nine met specific selection criteria. Four of the randomized controlled trials compared the efficacy of vitamin D with a placebo on severity of AD and were included in the meta-analysis. The vitamin D supplementation interventions showed a higher mean difference in severity of AD symptoms (mean difference = -5.81, 95% CI: -9.03 to -2.59, P = 0.0004, I(2) = 50%). CONCLUSIONS: Vitamin D has a potentially significant role for improving the symptoms of AD. The results from this study suggest that vitamin D supplementation may help ameliorate the severity of AD, and can be considered as a safe and tolerable therapy. However, larger-scale studies over a longer duration of treatment are needed to confirm this conclusion.

RESUMEN

BACKGROUND: The pathogenesis of atopic dermatitis (AD) remains to be determined; recently a possible change in the immune system with production of immunoglobulins is proposed. As vitamin E is a potent antioxidant, with the ability to decrease the serum levels of immunoglobulin E (IgE) in atopic patients, we aimed to evaluate the effect of oral vitamin E on treatment of AD. MATERIALS AND METHODS: This randomized, double-blind, placebo-controlled trial comprised seventy participants with mild-to-moderate AD, based on the Hanifin and Rajka diagnostic criteria. The patients were randomly selected from teaching skin clinics in Isfahan, Iran. They were randomly assigned to two groups of equal number, receiving vitamin E (400 IU/day) and placebo for four 4 months. Each month, the extent, severity, and subjective symptoms including itch and sleeplessness were measured by SCORAD index. Three months after the end of intervention, the recurrence rate was assessed. RESULTS: The improvement in all symptoms, except sleeplessness, was significantly higher in the group receiving vitamin E than in controls (-1.5 vs. 0.218 in itching, -10.85 vs. -3.54 in extent of lesion, and -11.12 vs. -3.89 in SCORAD index, respectively, P < 0.05). Three months after the end of intervention, the recurrence rate of AD was evaluated. Recurrence rate between all 42 individuals, who remained in the study, was 18.6%. Recurrence ratio of the group receiving vitamin E compared to the placebo group was 1.17, without significant differences between the two groups (P > 0.05). CONCLUSION: This study suggests that vitamin E can improve the symptoms and the quality of life in patients with AD. As vitamin E has no side effects with a dosage of 400 IU/day, it can be recommended for the treatment of AD.

RESUMEN

BACKGROUND: Atopic dermatitis, a chronic recurrent disease, is frequently encountered in clinical practice. In the last 30 years, the prevalence of atopic dermatitis has rapidly increased due to industrialization. Therefore, there have been attempts in recent years to find new ways of treating and preventing atopic dermatitis. OBJECTIVE: In this double-blind, randomized, placebo-controlled study, a combination of Bifidobacterium bifidum, Lactobacillus acidophilus, Lactobacillus casei, and Lactobacillus salivarius strains were evaluated in the treatment of atopic dermatitis in pediatric patients. METHODS: Forty pediatric patients (23 males and 17 females) aged 1~13 years were enrolled. One eligible individual who was approached declined to participate. The probiotic group was administered a probiotic complex containing B. bifidum, L. acidophilus, L. casei, and L. salivarius for 8 weeks. The placebo group, on the other hand, was administered skim milk powder and dextrose. All of the parameters including serum cytokines, eosinophil cationic protein), SCORing Atopic Dermatitis (SCORAD) index, and total serum immunoglobulin E (IgE) were measured in both the probiotic group and the placebo group at the end of 8 weeks. RESULTS: Probiotic intervention in pediatric atopic dermatitis patients effectively reduced the SCORAD index and serum cytokines interleukin (IL)-5, IL-6, interferon (IFN)-γ, and total serum IgE levels, but did not reduce levels of serum cytokines IL-2, IL-4, IL-10, ECP, or tumor necrosis factor-α (TNF-α) compared to the placebo group. CONCLUSION: Our study found probiotics to be effective in reducing atopic dermatitis patients' SCORAD index, serum IL-5, IL-6, IFN-γ, and total serum IgE levels but not effective in reducing serum IL-2, IL-4, IL-10, ECP, or TNF-α levels.

RESUMEN

Several studies on the pathogenesis of allergy both in man and experimental animals continue to show the importance of commensal bacteria in the gastrointestinal tract in stimulating and directing the immune system. The interest in modulating commensal bacteria flora with pre- and probiotics to prevent and treat food allergy has multiplied in recent years. We recently studied 230 infants with atopic dermatitis and suspected cow's milk allergy. The infants were randomly allocated to groups which received Lactobacillus GG (LGG), a mixture of four probiotic strains (MIX) or placebo for 4 weeks. We inferred that probiotics induce systemically detectable low-grade inflammation, which may explain the clinical effects and the secretion pattern of cytokines induced by PBMC. To study the ability of probiotics to prevent allergy in children, we recruited 1223 pregnant women carrying fetuses at increased risk of allergy for a double-blind placebo-controlled trial. Mothers used a mixture of four probiotic bacteria or a placebo from the 36th week of gestation. Their infants received the same probiotics plus prebiotic galacto-oligosaccharides for 6 months. At the 2-year follow-up, a total of 925 infants participated. The cumulative incidence of allergic disease did not differ significantly between the synbiotic and the placebo group. However, synbiotics significantly reduced eczema. The preventive effect of synbiotics was more pronounced against IgE-associated diseases. At the 5 year follow-up, 891(88%) of the 1018 intention-to-treat infants attended. In the probiotic and placebo groups, frequencies of allergic symptoms and IgE-associated allergic disease and sensitization were similar, and the frequencies of eczema did not differ between the groups. Atopic eczema, allergic rhinitis and asthma appeared equal frequency in the groups. However, less IgE-associated allergic disease occurred in the cesarean-delivered infants given probiotics. In cesarean-delivered childen, we noticed a delayed rise in bifidobacteria recovery in placebo-treated children which was corrected by pro- and prebiotic supplementation. Indications from studies of feces and blood at the age 6 months suggest that probiotics may enhance both inflammation and immune defence of the gut. The probiotic treatment further stimulated maturation of the immune system since the infants given probiotics showed increased resistance to respiratory infections and improved vaccine antibody responses.
