ABSTRACT
Objective:To investigate clinical features of patients with chronic spontaneous urticaria (CSU) in China.Methods:A questionnaire survey was carried out in CSU patients at the first visit and 4 follow-up visits in Departments of Dermatology of 12 third-grade hospitals in northern and southern China from January to December 2019. The survey content included demographic characteristics, pruritus intensity, the number of wheals, concomitant symptoms (such as pain in skin lesions, arthralgia, fever) during the last week prior to the admission, classification and subtypes of urticaria, and previous and current treatment regimens, etc., and the 7-day urticaria activity score (UAS7) was used to evaluate the therapeutic effect. Patients from 9 hospitals in Sichuan, Hubei and Fujian provinces were enrolled into the southern China group, and patients from 3 hospitals in Beijing municipality and Liaoning province were enrolled into the northern China group. Differences between groups were analyzed by two-independent-sample t-test, Mann-Whitney U test or chi-square test. Results:Overall, 1 396 CSU outpatients were enrolled, including 592 males and 804 females; their age was 38.32 ± 16.13 years, 1 109 (79.5%) were aged between 20 and 60 years, and 660 (47.3%) were aged between 20 and 40 years. Their age at onset was 35.85 ± 16.03 years, and the disease duration was 0.50 (0.25, 2.00) years. Allergic diseases were the most common concomitant diseases, 269 (19.3%) patients were diagnosed with accompanied allergic rhinitis or conjunctivitis, 169 (14%) with accompanied eczema/dermatitis, 39 (2.8%) with accompanied asthma; only 19 (1.4%) CSU patients had a history of thyroid diseases, but 133 (9.5%) were positive for anti-thyroid peroxidase (TPO) or anti-thyroglobulin (Tg) antibodies at the visit; elevated serum total IgE levels were observed in 437 (31.3%) patients, and 104 (7.4%) were positive for autoantibodies. There were 1 078 (77.2%) patients in the southern China group and 318 (22.8%) in the northern China group, and the southern China group showed significantly longer disease duration (2.16 ± 4.76 years vs. 1.53 ± 2.80 years, P < 0.001) , and significantly higher proportions of patients with family history (10.7% vs. 3.5%) , with painful lesions (5.8% vs. 0.9%) , and those with arthralgia (10.7% vs. 0) compared with the northern China group (all P < 0.05) . The three most prevalent urticaria subtypes were CSU (835 cases, 49.9%) , symptomatic dermographism (437 cases, 31.3%) , and angioedema (138 cases, 9.9%) , and the proportion of patients with the single diagnosis of CSU was significantly higher in the southern China group (53%) than in the northern China group (38.9%, P < 0.001) . In terms of treatment, 1 365 (97.8%) patients received conventional-dose second-generation H1 antihistamines alone or in combination, and only 31 (2.2%) were treated with antihistamines at high doses; other medicines were mostly administered in combination, and compound glycyrrhizin was most frequently prescribed (36.6%) , while omalizumab was only administered in 7 patients (0.5%) . Conclusions:Significant differences in the clinical features of CSU were observed between northern and southern China. Nowadays traditional modalities are inadequate for the treatment of CSU, and new therapeutic drugs are somewhat promising.
ABSTRACT
Allergic contact dermatitis (ACD) is a T cell-mediated inflammatory skin disease induced by contact allergens. The role of mast cells in ACD remains controversial. In the sensitization phase, mast cells play a pro-inflammatory role by releasing inflammatory cytokines to promote recruitment of neutrophils, and affect the sensitization process by stimulating or inhibiting the migration of dendritic cells. During the elicitation phase, mast cells promote non-allergen-specific inflammation, and enhance allergen-specific inflammation in moderate ACD, but inhibit allergen-specific inflammation in severe and chronic ACD. In addition to the IgE-Fcε receptor I-histamine pathway, Mas-related G-protein coupled receptor B2/X2 (MrgprB2/X2) can mediate the activation of mast cells, leading to the release of tryptase to drive non-histaminergic itch, and may serve as a new target for the treatment of ACD.
ABSTRACT
Objective:To evaluate clinical efficacy and safety of calcium-based antimicrobial peptide compounds cooling gel (CAPCS cooling gel) in the treatment of atopic dermatitis (AD) .Methods:A randomized, double-blind, active-controlled clinical study was conducted. From July 2019 to May 2020, 80 adult patients with mild-to-moderate AD were enrolled from Beijing Friendship Hospital, Capital Medical University, and randomly and equally divided into 2 groups: test group topically treated with CAPCS cooling gel, control group topically treated with hydrocortisone cream, and the treatment was performed thrice a day for 4 consecutive weeks. Before, 1, 2 and 4 weeks after the start of treatment, efficacy was evaluated according to the Eczema Area and Severity Index (EASI), Visual Analog Scale (VAS), and Investigator′s Global Assessment (IGA) scores, and adverse events were recorded. Efficacy and safety were compared by using repeated measures analysis of variance and chi-square test.Results:Of the 80 patients with AD, 43 were males and 37 were females, and the age was 52.71 ± 16.71 years. Before the treatment, there was no significant difference in gender, age, EASI, VAS or IGA scores between the two groups (all P > 0.05). After 1- and 2-week treatment, there was no significant difference in the response rate between the test group (10.00% [4/40], 57.50% [23/40], respectively) and control group (15.00% [6/40], 52.50% [21/40] respectively, both P > 0.05). After 4-week treatment, the response rate was significantly higher in the test group (82.50%, 33/40) than in the control group (57.50%, 23/40, P < 0.05). Compared with the control group, the test group showed significantly decreased VAS scores after 1-, 2- and 4-week treatment ( U = 1253.00, 1121.00, 1091.50, respectively, all P < 0.05). No drug-related adverse events were observed in either of the groups. Conclusion:CAPCS cooling gel is safe and effective in the treatment of mild-to-moderate AD in adults, and can be applied in clinic.

ABSTRACT
The JAK-STAT signaling pathway, composed of Janus kinase (JAK) and signal transducer and activator of transcription (STAT), is an important intracellular signaling pathway. It is involved in the occurrence of many inflammatory diseases. Blocking this pathway by JAK inhibitors has become an effective approach to the treatment of some diseases, such as rheumatoid arthritis and ulcerative colitis. However, JAK inhibitors have not been approved for the treatment of skin diseases at present. This review summarizes application prospects of JAK inhibitors in the treatment of skin diseases.
ABSTRACT
Objective:To evaluate the efficacy of acrivastine alone or in combination with loratadine in the treatment of chronic refractory urticaria.Methods:From March 2017 to December 2018, a multicenter, randomized, controlled clinical study was conducted in 4 centers. Patients with chronic refractory urticaria were randomly divided into two groups, i.e., combined treatment group receiving oral acrivastine capsules 8 mg thrice a day plus oral loratadine tablets 10 mg once a day, and acrivastine alone group receiving oral acrivastine capsules 8 mg thrice a day plus a placebo 10 mg once a day. The course of treatment was 4 weeks. Visits were scheduled at baseline and after 1, 2 and 4 weeks of treatment. At the same time, clinical data were collected, and adverse events were recorded. Symptom scores were evaluated based on degree of itching, number and size of wheals, duration of each attack and number of attacks per week, and symptom score reduce index (SSRI) was used to evaluate the efficacy. Repeated measures analysis of variance and chi-square test were used to evaluate the efficacy and safety.Results:Fifty-three patients in the combined treatment group and 59 in the acrivastine alone group were included in the efficacy analysis. Before treatment, there was no significant difference in symptom score or visual analogue score between the two groups. After 2 weeks of treatment, 19 patients were cured and 10 achieved marked improvement in the combined treatment group, with a response rate of 54.72%; 15 were cured and 6 achieved marked improvement in the acrivastine alone group, with a response rate of 35.59%. After 4 weeks of treatment, 23 patients were cured and 9 achieved marked improvement in the combined treatment group, with a response rate of 60.38%; 20 were cured and 2 achieved marked improvement in the acrivastine alone group, with a response rate of 37.29%. After 2 and 4 weeks of treatment, the response rates were significantly higher in the combined treatment group than in the acrivastine alone group ( χ2 = 4.13, 5.96 respectively, both P < 0.05) . The SSRI significantly differed among different follow-up time points, as well as between the 2 groups ( F = 8.62, 4.38 respectively, both P < 0.05) . Multivariate analysis of variance showed that SSRI was significantly higher in the combined treatment group (0.63 ± 0.05, 0.68 ± 0.05, respectively) than in the acrivastine alone group (0.47 ± 0.05, 0.51 ± 0.05, respectively) after 2 and 4 weeks of treatment (both P < 0.05) . Drug-related adverse reactions, including drowsiness, stomach upsets, headache and liver function abnormality, occurred in 7 patients in the combined treatment group, as well as in 3 in the acrivastine alone group. Conclusion:Acrivastine is safe and effective for the treatment of chronic refractory urticaria, and acrivastine combined with loratadine can markedly improve the efficacy.

Objective To evaluate the efficacy and safety of Qingpeng ointment for the treatment of localized eczema in children.Methods A multicenter,randomized,open-labeled,tacrolimus 0.03％ ointment-controlled clinical trial was conducted.A total of 442 children with localized eczema were enrolled into this study,and divided into 2 groups to topically apply Qingpeng ointment (Qingpeng group) and tacrolimus 0.03％ ointment (tacrolimus group) respectively twice a day for 2 weeks.The children were followed up before the treatment and 1,2 weeks after the treatment,and the efficacy and safety were evaluated at the same time.Results Clinical data from 426 children were included in the efficacy analysis.At 1,2 weeks after the treatment,there were no significant differences in the response rate between the Qingpeng group and tacrolimus group (1 week after the treatment:78.92％ vs.81.77％,x2 =0.545,P =0.460;2 weeks after the treatment:98.65％ vs.97.54％,x2 =0.721,P =0.396).However,the pruritus scores at 1,2 weeks after the treatment were both significantly lower in the Qingpeng group than in the tacrolimus group (1 week:F =14.001,P =0.000;2 weeks:F =11.252,P =0.001).At 1 week after the treatment,the incidence rate of adverse reactions was significantly lower in the Qingpeng group than in the tacrolimus group (P ＜ 0.05).Mild itching,burning sensation and other local irritant sensations were the most common adverse reactions.Conclusion Qingpeng ointment is safe and effective for the treatment of localized eczema in children with good tolerability.
ABSTRACT
Although tumor immunotherapy has been proposed for many years,the consensus denoting it as an essential approach for fighting against cancer is reached only in recent years. Tumor immunotherapy can be categorized as active and passive ones. In order to successfully cure cancer,safe and efficient active immunotherapy is required. Dendritic cells (DCs)are not only the bridge linking innate and adaptive immunity,but also the key determinants of the quality of adaptive immunity:immunity versus immune tolerance. Therefore,the safe and efficient DC-based tumor-specific and broad-spectral tumor vaccine has an irreplaceable important position in tumor immunotherapy. Because of the high heterogeneity of DCs, the research on DC-based tumor vaccine has encountered a bottleneck. Here,we reviewed the progress in research on DC-based tumor vaccine and related problems needed to be resolved with the incorporation of our experiences.
ABSTRACT
Objective To estimate effects of Qingpeng ointment on skin barrier function,and to explore their potential mechanisms.Methods A total of 12 female volunteers with xerosis on the extensor surfaces of legs were enrolled into this study.All the volunteers were topically treated with Qingpeng ointment on the right leg (Qingpeng side) and its vehicle on the left leg (vehicle side) twice daily for 7 consecutive days.Skin barrier function-associated indexes including transepidermal water loss (TEWL) and the water content of the stratum corneum were measured before the treatment,after 3-and 7-day treatment separately.Thirty-six BALB/c female mice were randomly and equally divided into 6 groups:a blank control group receiving no induction or treatment,a model group induced by 2,4-dinitrofluorobenzene (DNFB) on the back for 5 consecutive weeks,3 Qingpeng groups and a vehicle group induced by DNFB on the back for 5 consecutive weeks followed by topical treatment with different concentrations (50％,75％,100％) of Qingpeng ointment or its vehicle twice a day for 2 consecutive weeks.At the end of treatment,skin appearance of mice was observed with naked eyes,skinfold thickness and TEWL were measured.Then,all the mice were sacrificed,and skin tissue specimens were resected from the back of mice followed by histopathologic examination and immunohistochemical staining for the detection of filaggrin (FLG),involucrin (IVL) and kallikrein 7 (KLK7) expressions in the epidermis.Results After start of treatment,both the Qingpeng side and vehicle side showed significantly decreased TEWL on day 3 (t =2.651,2.996,respectively,both P＜ 0.05) and 7 (t =3.615,3.586,respectively,both P＜ 0.05),but increased water content of the stratum corneum on day 3 (t=9.029,5.830,respectively,both P＜ 0.001) and 7 (t =13.842,11.299,respectively,both P ＜ 0.001) compared with those before the treatment.However,no significant differences were observed in TEWL or the water content of the stratum corneum between the Qingpeng side and vehicle side at any of the time points (all P ＞ 0.05).In addition,there were no marked differences in mouse skin appearance,skinfold thickness or histopathologic manifestations between the vehicle group and model group,while the manifestations of dermatitis were attenuated to different extents in the three Qingpeng groups compared with the model group.Both TEWL and KLK7 expression levels were significantly decreased in the vehicle group and three Qingpeng groups compared with the model group (all P ＜ 0.05),but similar between the vehicle and Qingpeng groups (all P ＞ 0.05).Conclusion The vehicle of Qingpeng ointment can improve skin barrier function.
