RESUMEN

AIM: Symptomatology and severity of atopic dermatitis (AD) can be objectively measured with equipment. This study aimed to compare skin measurements and investigate their correlations with various clinical severity scores. METHODS: Skin hydration (SH), transepidermal water loss (TEWL), pH, erythema, pigmentation, and ITA (individual typology angle) were measured (using Delfin, Courage + Khazaka, and Mettler Toledo equipment), and correlated with Patient-Oriented Eczema Measure (POEM, a short-term subjective-symptom score), Scoring Atopic Dermatitis (SCORAD, a short-term subjective-symptom and objective-sign score), Nottingham Eczema Severity Score (NESS, a long-term subjective-symptom score), Children Dermatology Life Quality Index (CDLQI, a short-term subjective-symptom score) with Spearman's rho coefficient. RESULTS: 80 sets of clinical scores from eczema patients (mean age: 10.8 ± 4.9 years; 44.6% male) were evaluated. The POEM, objective SCORAD, CDLQI correlated well with each other. Skin pH ranged from 4.3 to 7.0 (mean 5.7 ± 0.61). Skin pH was correlated with Objective SCORAD components, including area (rho = 0.269, p = .036), erythema (rho = 0.302, p = .018), and lichenification (rho = 0.365, p = .026) and with the usage frequency of topical antibiotics. Skin pH was also correlated with other skin measurements, including SH (Delfin equipment: rho = -0.38, p < .001). SH and TEWL as measured by Delfin equipment correlated better with a number of symptoms and signs than Courage + Khazaka equipment. Other clinical measurements including erythema, melanin, and skin color did not demonstrate strong correlations with clinical symptom scores. CONCLUSION: Skin pH (using Mettler Toledo), SH, and TEWL (using Delfin equipment) correlated well with various clinical symptomatology scores. Less acidic pH appears to be associated with worse clinical scores of symptomatology, and increase usage of topical antibiotics, These findings not only support the supplementary usage of equipment in aiding objective documentation of clinical symptomatology in eczema therapeutic research but also the advocacy of maintaining more acidic skin and avoiding alkaline soap and emollient products.

RESUMEN

Background: Few standardized bath product clinical trials were performed for atopic dermatitis patients. Pine-tar and green tea extracts are plant-derived products that have been described as having anti-allergic effects which may reduce AD disease severity. Methods: The efficacy of two complementary bath products was studied and compared. Efficacy and acceptability of the bath products were measured by patient general acceptability of treatment (GAT: very, good, fair or poor), disease severity (SCORAD: SCoring Atopic Dermatitis), quality of life (CDLQI: Children Dermatology Life Quality Index), and pertinent clinical parameters were measured before and after four weeks of treatment. Sample size calculations for further clinical trials were performed. In one group, nine AD patients were subjected to bathing with a pine-tar bath oil for 10⁻15 min daily for four weeks. In another group, 20 AD subjects bathed with a teabag containing green tea extracts for four weeks. Results: Significant improvements in clinical- and patient-orientated parameters were found in the pine-tar bathing group, but not the tea-bag bathing group. Both groups reported very good/good GAT on the studied products. Teabag bathing was considered not efficacious for further clinical trials. Conclusions: The pilot studies provided preliminary data on the efficacy of pine tar bath oil. We do not document a significant efficacy for bathing with tea extracts. Bathing with pine-tar is potentially a complementary topical treatment with good patient acceptance and adherence, but further evidence-based research for its recommendations is needed.

RESUMEN

BACKGROUND: Asthma is a significant chronic health problem worldwide. Management aims at disease control by reducing functional impairment and exacerbations and improving quality of life (QoL). We report a multi-center study to survey asthma control and QoL in four cities in the Pearl River Delta. METHODS: The conjoint survey involved ten Hong Kong pediatric hospitals/units, two Shenzhen hospitals, two Macau hospitals, and two Guangzhou hospitals on asthma control (using Asthma Control Test) and QoL (Pediatric Allergic Disease Quality of Life Questionnaire, PADQLQ). Acceptability of a treatment is graded as very good/good/fair/poor. RESULTS: Good asthma control was only reported in 80% subjects in Hong Kong, but higher in sister cities (85-94%, P < 0.001). Allergic rhinitis, "incense burning", and "smoker in family" were prevalent among the four cities. Logistic regression showed better control of asthma was associated with better PADQLQ (B = - 0.029, P < 0.001), better acceptability of bronchodilator (B = - 1.488, P = 0.025), negatively with "smoker in family" (B = - 0.83, P = 0.015) and various PADQLQ domains. Conversely, worse PADQLQ was associated with allergic rhinitis severity (B = 4.77, P < 0.001), poor control of asthma (B = 7.56, P < 0.001), increased frequency of traditional Chinese medicine use (B = 1.7, P < 0.05), increased frequency of bronchodilator usage (B = 1.05, P < 0.05), "smoker in family" (B = 4.05, P < 0.05), and incense burning at home (B = 3.9, P < 0.05). CONCLUSIONS: There are some clinical and cultural differences among the four southern Chinese cities within the Guangdong province. This study identifies potentially modifiable environmental and treatment factors associated with poor asthma control and QoL for health-care interventions. Having a smoker in the family is independently associated with poor asthma control and QoL.

RESUMEN

AIM: Eczema or Atopic Dermatitis (AD) is associated with itch, sleep disturbance, impaired life quality, reduced skin hydration, impaired epidermal barrier function and colonization by Staphylococcus aureus (SA). We investigated an emollient with claimed multi-actions on barrier repair, antihistaminergic and antimicrobial effects. METHODS: Consecutive AD patients were recruited. Swabs and cultures from eczematous areas, disease severity (SCOring Atopic Dermatitis score: SCORAD), quality-of-life (Children Dermatology Life Quality Index, CDLQI), Skin Hydration (SH), and Transepidermal Water Loss (TEWL) were obtained before and 4-week following usage of the emollient. Global or General Acceptability of Treatment (GAT) was obtained (as very good, good, fair or poor). RESULTS: 30 AD patients were recruited. 73% reported "very good" or "good", whereas 27% reported "fair" or "poor" GAT of the emollient. Following the use of the multi-action emollient, area affected, disease intensity and severity significantly improved, especially in the very good/good group (p=0.006-0.035). There was no significant improvement of itch or sleep scores, quality of life, SH, TEWL, S. aureus colonization status, or use of topical treatments. When compared with the historical data of another product, there was no statistical difference between the two creams. CONCLUSION: The emollient is acceptable in nearly three-quarter of AD patients. Patients that accept the moisturizer have less area affected, disease intensity and severity than the non-accepting counterparts following its usage. Despite claim for multi-action, there were no appreciable quality-oflife, anti-itch, skin barrier, and anti-microbial effects.

RESUMEN

BACKGROUND: Eczema or Atopic Dermatitis (AD) is a common chronic relapsing skin disease associated with impaired quality of life. Regular usage of moisturizer/emollient is the mainstay of management but acceptability of emollient is often suboptimal. We investigated if emollient acceptability is influenced by various clinical factors in AD. METHODS: A survey on frequency of emollient usage, brands, clinical factors including disease severity (Nottingham Eczema Severity Score, NESS), quality of life (Children Dermatology Life Quality Index, CDLQI), Transpidermal Water Loss (TEWL), and Skin Hydration (SH) was performed. Acceptability was classified as very good, good, fair or poor. RESULTS: We evaluated 128 AD patients. NESS correlated with CDLQI and the treatment domain of CDLQI. Emollient usage is elementary for AD treatment. 89.1% of patients reported that doctor's recommendation was the major source of advice when choosing an emollient. Aqueous cream (AQ) and petroleum-derived products were among the commonly used emollients. More aqueous cream users reported fair/poor acceptability (p=0.017) and lower SH (p<0.05). Linear regression showed that patients who thought their emollient as fair or poor were currently using AQ (p=0.003), their emollient not recommended by a doctor (p=0.035), with more severe disease (p=0.04), and had lower emollient usage in winter (p=0.05). CONCLUSION: Physicians play a pivotal role in assisting patients to select an emollient that they will accept and use consistently. The studied emollients are generally acceptable by over 80% patients. However, aqueous cream is least acceptable by patients, making it the least favorable emollient to recommend to patients.

RESUMEN

Childhood eczema or atopic dermatitis (AD) is a distressing disease associated with pruritus, sleep disturbance, impaired quality of life and Staphylococcus aureus isolation. The pathophysiology of AD is complex and various seromarkers of immunity are involved. We investigated if anti-staphylococcal enterotoxin IgE (anti-SE), selected seromarkers of T regulatory (Treg), T helper (Th) and antigen-presenting cells (APC) are associated with clinical signs of disease severity and quality of life. Disease severity was assessed with the Scoring Atopic Dermatitis (SCORAD) index, and quality of life with the Children's Dermatology Life Quality Index (CDLQI) in AD patients ≤18 years old. Concentrations of anti-staphylococcus enterotoxin A and B immunoglobulin E (anti-SEA and anti-SEB), selected Treg/Th/APC chemokines, skin hydration and transepidermal water loss (TEWL) were measured in these patients. Forty patients with AD [median (interquartile range) age of 13.1 (7.9) years) were recruited. Backward stepwise linear regression (controlling for age, personal allergic rhinitis and asthma, and other blood markers) showed the serum anti-SEB level was positively associated with S. aureus and S. epidermidis isolations, objective SCORAD, clinical signs and CDLQI. TNF-α (a Th1 cytokine) was positively associated with objective SCORAD (B = 4.935, p = 0.010), TGF-ß (a Treg cytokine) negatively with disease extent (B = -0.015, p = 0.001), IL-18 (an APC cytokine) positively with disease extent (B = 0.438, p = 0.001) and with TEWL (B = 0.040, p = 0.010), and IL-23 (an APC cytokine) negatively with disease extent (B = -2.812, p = 0.006) and positively with pruritus (B = 0.387, p = 0.007). CONCLUSIONS: Blood levels of anti-SEB, Th1, Treg and APC cytokines are correlated with various clinical signs of AD. AD is a systemic immunologic disease involving Staphylococcus aureus, cellular, humoral, cytokine and chemokine pathophysiology.
