    特应性皮炎(AD),牛皮癣,与红皮病相关的药物反应经常因感染而复杂化。然而,血流感染(BSI)受到的研究关注较少。
    本研究旨在探讨红皮病患者与BSI相关的临床特征和危险因素。
    对141例红皮病病例进行回顾性分析。11例患者被确定为患有BSI。回顾并比较了BSI和非BSI组的临床记录。
    在7.80%(11/141)的红皮病病例中诊断出BSI,在AD中分解为7.14%,2.00%的牛皮癣,药物反应占17.14%。值得注意的是,所有阳性皮肤培养物(7/7)均显示细菌分离株与血液培养物一致。单因素logistic回归分析显示与BSI有几个显著关联,包括温度(≤36.0或≥38.5°C;比值比(OR)=28.06;p<0.001),冷却(OR=22.10;p<0.001),肾脏疾病(OR=14.64;p<0.001),药物反应的病因(OR=4.18;p=0.03),白蛋白(ALB)(OR=0.86;p<0.01),C反应蛋白(CRP)(OR=1.01;p=0.02),白细胞介素6(IL-6)(OR=1.02;p=0.02),和降钙素原(PCT)(OR=1.07;p=0.03)。受试者工作特征(ROC)曲线显示与ALB显著相关(p<0.001;曲线下面积(AUC)=0.80),PCT(p=0.009;AUC=0.74),和CRP(p=0.02;AUC=0.71)。
    提高对BSI风险的认识在红皮病管理中至关重要。有特定危险因素的患者,如体温异常(≤36.0或≥38.5℃),令人不寒而栗的感觉,肾病,有药物反应史,CRP升高(≥32mg/L),PCT升高(≥1.00ng/ml),和低白蛋白(≤31.0g/L),需要密切监测BSI的发展。
    UNASSIGNED: Atopic dermatitis (AD), psoriasis, and drug reactions associated with erythroderma are frequently complicated by infections. However, bloodstream infection (BSI) have received less research attention.
    UNASSIGNED: This study aimed to investigate the clinical characteristics and risk factors associated with BSI in patients with erythroderma.
    UNASSIGNED: A retrospective analysis was conducted on 141 erythroderma cases. Eleven cases were identified as having BSI. Clinical records of both BSI and non-BSI groups were reviewed and compared.
    UNASSIGNED: BSI was diagnosed in 7.80% (11/141) of erythroderma cases, with a breakdown of 7.14% in AD, 2.00% in psoriasis, and 17.14% in drug reactions. Notably, all positive skin cultures (7/7) showed bacterial isolates concordant with blood cultures. Univariate logistic regression analysis revealed several significant associations with BSI, including temperature (≤36.0 or ≥38.5 °C; odds ratio (OR) = 28.06; p < 0.001), chilling (OR = 22.10; p < 0.001), kidney disease (OR = 14.64; p < 0.001), etiology of drug reactions (OR = 4.18; p = 0.03), albumin (ALB) (OR = 0.86; p < 0.01), C-reaction protein (CRP) (OR = 1.01; p = 0.02), interleukin 6 (IL-6) (OR = 1.02; p = 0.02), and procalcitonin (PCT) (OR = 1.07; p = 0.03). Receiver operating characteristic (ROC) curves demonstrated significant associations with ALB (p < 0.001; the area under curve (AUC) = 0.80), PCT (p = 0.009; AUC = 0.74), and CRP (p = 0.02; AUC = 0.71).
    UNASSIGNED: Increased awareness of BSI risk is essential in erythroderma management. Patients with specific risk factors, such as abnormal body temperature (≤36.0 or ≥38.5 °C), chilling sensations, kidney disease, a history of drug reactions, elevated CRP (≥32 mg/L), elevated PCT (≥1.00 ng/ml), and low albumin (≤31.0 g/L), require close monitoring for BSI development.

    背景:伴嗜酸性粒细胞增多和全身症状(DRESS)综合征的药物反应是一种严重的,对经常涉及终末器官损伤的罪魁祸首药物的危及生命的反应。皮质类固醇是DRESS综合征的一线治疗方法;然而,某些患者人群可能禁用皮质类固醇。目前文献中报道的仅有54例详述使用环孢素治疗DRESS综合征的病例。
    目的:本系列病例的目的是通过汇总症状缓解时间,在大型患者队列中检查环孢素对DRESS综合征的治疗。复发率,以及治疗剂量和持续时间。
    方法:本研究为回顾性队列研究。包括2015年至2019年由董事会认证的皮肤科医生诊断为DRESS综合征并在科罗拉多大学医院接受治疗的患者。
    结果:19例DRESS综合征符合我们的纳入标准。短期服用环孢菌素,我们队列中的19例患者中有17例(89%)症状缓解(平均治疗时间为5.26天)。使用环孢素治疗后DRESS综合征的复发发生在19例队列中的3例(16%)。
    结论:我们的研究支持使用环孢素治疗DRESS综合征,特别是在无法维持长期免疫抑制的患者中。在更大的研究人群中,需要进一步的研究来比较环孢素与当前治疗标准的疗效,并调查长期结果。
    BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe, life-threatening reaction to a culprit drug that frequently involves end-organ damage. Corticosteroids are the first-line treatment for DRESS syndrome; however, corticosteroids may be contraindicated in certain patient populations. There are currently only 54 cases detailing the use of cyclosporine for the treatment of DRESS syndrome reported in the literature.
    OBJECTIVE: The aim of this case series was to examine the treatment of DRESS syndrome with cyclosporine in a large patient cohort by aggregating time to symptom resolution, recurrence rate, and treatment dose and duration.
    METHODS: This study was a retrospective cohort study. Patients diagnosed with DRESS syndrome by a board-certified dermatologist and treated at the University of Colorado Hospital from 2015 to 2019 were included.
    RESULTS: Our inclusion criterion was met by 19 occurrences of DRESS syndrome. With a short course of cyclosporine, 17 of 19 patients in our cohort (89%) had resolution of symptoms (mean treatment length of 5.26 days). DRESS syndrome\'s relapse after treatment with cyclosporine occurred in 3 of 19 (16%) occurrences of the cohort.
    CONCLUSIONS: Our study supports the use of cyclosporine in the treatment of DRESS syndrome, particularly in patients who are unable to sustain prolonged immunosuppression. Further research is necessary to compare the efficacy of cyclosporine to the current standard of care in a larger study population and investigate long-term outcomes.

  • 文章类型: Observational Study
    背景:自2002年SCAR研究以来,多形性红斑(EM),感染后的疾病,与史蒂文斯-约翰逊综合征(SJS)不同,药物诱导的。然而,EM病例仍在法国药物警戒数据库(FPDB)中报告。
    目的:描述FPDB中报告的EM,并比较报告的质量和特征。
    方法:这项回顾性观察性研究选择了FPDB报告的两个时期的所有EM病例:第1期(P1,2008-2009年)和第2期(P2,2018-2019年)。纳入标准为1)临床典型EM的诊断和/或由皮肤科医生验证;2)报告的反应发生日期;和3)药物暴露的精确时间顺序。病例被分类为确诊的EM(典型的肢端靶病变和/或皮肤科医生的确认)和可能的EM(未指定的靶病变,孤立的粘膜受累,怀疑SJS)。当EM被证实时,我们得出结论可能是药物诱导的EM,发病5至28天,没有其他原因。
    结果:在182个选定的报告中,140(77%)进行了分析。其中,67(48%)提出了比EM更可能的替代诊断。在最终纳入的73例EM病例报告中(P1,n=41;P2,n=32),36(49%)有可能的非药物原因,28(38%)与起效时间≤4天和/或≥29天的药物有关。9例保留了可能的药物诱导的EM(可评估报告的6%)。在第2期比第1期更经常进行病因检查(53.1%vs29.3%,P=0.04),在第2期,发病时间从5天到28天更为频繁(59.2%vs40%,P=0.04)。
    结论:这项研究表明可能的药物诱导的EM是罕见的。许多报告描述了“多态”皮疹,不适当地得出结论为EM或感染后EM,具有不适当的药物问责制,受到原病变偏倚的影响。
    BACKGROUND: Since the 2002 SCAR study, erythema multiforme (EM), a post-infectious disease, has been distinguished from Stevens-Johnson syndrome (SJS), drug-induced. Nevertheless, EM cases are still reported in the French pharmacovigilance database (FPDB).
    OBJECTIVE: To describe EM reported in the FPDB and to compare the quality and the characteristics of the reports.
    METHODS: This retrospective observational study selected all EM cases reported in the FPDB over two periods: period 1 (P1, 2008-2009) and period 2 (P2, 2018-2019). Inclusion criteria were 1) a diagnosis of clinically typical EM and/or validated by a dermatologist; 2) a reported date of onset of the reaction; and 3) a precise chronology of drug exposure. Cases were classified confirmed EM (typical acral target lesions and/or validation by a dermatologist) and possible EM (not-otherwise-specified target lesions, isolated mucosal involvement, doubtful with SJS). We concluded possible drug-induced EM when EM was confirmed, with onset ranging from 5 to 28 days without an alternative cause.
    RESULTS: Among 182 selected reports, 140 (77%) were analyzed. Of these, 67 (48%) presented a more likely alternative diagnosis than EM. Of the 73 reports of EM cases finally included (P1, n=41; P2, n=32), 36 (49%) had a probable non-drug cause and 28 (38%) were associated with only drugs with an onset time ≤4 days and/or ≥29 days. Possible drug-induced EM was retained in 9 cases (6% of evaluable reports). Etiological work-up was more often performed in period 2 than 1 (53.1% vs 29.3%, P=0.04), and the time to onset from 5 to 28 days was more frequent in period 2 (59.2% vs 40%, P=0.04).
    CONCLUSIONS: This study suggests that possible drug-induced EM is rare. Many reports describe \"polymorphic\" rashes inappropriately concluded as EM or post-infectious EM with unsuitable drug accountability subject to protopathic bias.

    诸如巴西角蛋白治疗(BKT)之类的直发产品含有高浓度的甲醛,它的使用与副作用有关。2016年,首次描述了7例继发于BKT的湿疹样银屑病样皮肤反应。我们旨在研究由于BKT引起的银屑病样皮肤反应患者的临床特征和皮肤镜检查结果。
    2017年10月至2020年6月进行了一项横断面研究。包括使用BKT后头皮出现红斑和鳞屑的患者。年龄,性别,BKT的数量,BKT和皮肤反应之间经过的时间,拉力试验,和皮肤镜检查结果进行了调查。使用描述性和推断性统计。
    我们发现43名患者的平均年龄为35±10岁,42例(98%)以女性为主。BKT的平均数为2±2。出现反应的平均时间长度为12±17个月,这与BKT的数量有关(P=0.01)。37例(86%)患者的拉力试验为阳性。最常见的皮肤镜检查结果是42例(98%),35个红色斑块(81%),32(74%),类似于洋葱鳞茎的外皮。
    头发拉直产品被广泛使用,随后发生的牛皮癣样皮肤反应可能被诊断不足。重要的是要研究BKT的背景,并结合提示这种皮肤反应的临床和皮肤镜检查结果。
    UNASSIGNED: Hair straightening products like the Brazilian Keratin Treatment (BKT) contain high concentrations of formaldehyde, and its use is associated with adverse effects. In 2016, seven cases of eczema-like psoriasiform skin reaction secondary to BKT were described for the first time. We aim to investigate the clinical characteristics and dermatoscopic findings of patients with psoriasiform skin reactions due to BKT.
    UNASSIGNED: A cross-sectional study was performed from October 2017 to June 2020. Patients who developed erythema and scales on the scalp following the use of BKT were included. Age, sex, number of BKTs, time elapsed between BKT and the skin reaction, pull test, and dermatoscopic findings were investigated. Descriptive and inferential statistics were used.
    UNASSIGNED: We found 43 patients with a mean age of 35 ± 10 years, predominantly females in 42 (98%) cases. The mean number of BKTs was 2 ± 2. The mean length of time elapsed to present the reaction was 12 ± 17 months and this was related to the number of BKTs (P = 0.01). The pull test was positive in 37 (86%) patients. The most frequent dermatoscopic findings were perifollicular scales in 42 (98%), red patches in 35 (81%), and peripilar desquamation resembling the outer skin of an onion bulb in 32 (74%).
    UNASSIGNED: Hair straightening products are widely used and the psoriasiform skin reaction that develops afterward might be underdiagnosed. It is important to investigate the background of BKT in conjunction with the clinical and dermatoscopic findings suggestive of this cutaneous reaction.

    背景:治疗早期真菌病(MF)需要安全,皮肤导向疗法。药物副作用可导致有效疗法的利用不足。这项研究的目的是评估使用0.1%的局部曲安奈德软膏作为减少与局部甲胺/氯甲芬凝胶治疗MF相关的接触性皮炎的方法。
    方法:这种前瞻性,随机化,开放标签研究评估了2017年12月17日至2020年12月23日符合接受局部用甲氯胺/氯甲芬凝胶治疗条件的28例支原体病成人.患者治疗4个月,临床随访12个月。患者的一半病变也用0.1%的局部曲安奈德软膏治疗(而另一半仅用甲胺/氯甲芬治疗)。该研究是在接受每个治疗组的同一患者中使用单独的病变进行自我控制。通过掷硬币确定治疗臂。
    结果:28名患者(17名男性(61%)和11名女性(39%))。人口统计包括25个白人,2非洲裔美国人,1名亚洲患者。25人完成了为期12个月的随访。0.1%曲安奈德软膏可提高甲胺/氯甲芬凝胶的耐受性,但未改变甲胺/氯甲芬的功效。在第2个月时,曲安奈德治疗的手臂中,皮炎(SCORD评分)的统计学显着降低了50%。
    结论:当局部用甲胺/氯甲芬凝胶治疗患者时,局部用曲安奈德软膏是一种有用的辅助治疗。它减少炎症并且不降低功效。研究中皮炎的高峰发生率发生在第二个和第三个月。
    背景:ClinicalTrials.gov标识符,NCT03380026。
    BACKGROUND: Treatment of early-stage mycosis fungoides (MF) requires safe, skin-directed therapies. Medication side effects can lead to underutilization of effective therapies. The objective of this study was to assess the use of topical triamcinolone 0.1% ointment as a means of reducing contact dermatitis associated with topical mechlorethamine/chlormethine gel for the treatment of MF.
    METHODS: This prospective, randomized, open-label study evaluated 28 adults with mycosis fungoides who were eligible for treatment with topical mechlorethamine/chlormethine gel from December 17, 2017 to December 23, 2020. Patients were treated for 4 months with clinical follow-up through 12 months. Patients had half of their lesions also treated with topical triamcinolone 0.1% ointment (while the other half were treated with mechlorethamine/chlormethine alone). The study was self-controlled with separate lesions in the same patient receiving each treatment arm. Treatment arms were determined by the flip of a coin.
    RESULTS: Twenty-eight patients enrolled (17 men (61%) and 11 women (39%)). Demographics included 25 White, 2 African Americans, and 1 Asian patient. Twenty-five completed the 12-month follow-up. Triamcinolone 0.1% ointment led to increased tolerability of mechlorethamine/chlormethine gel but did not change the efficacy of mechlorethamine/chlormethine. There was a statistically significant 50% decrease in dermatitis (SCORD score) at month 2 in the triamcinolone-treated arm.
    CONCLUSIONS: Topical triamcinolone ointment is a helpful adjuvant therapy when treating patients with topical mechlorethamine/chlormethine gel. It diminishes inflammation and does not reduce efficacy. The peak incidence of dermatitis in the study occurred in the second and third months.
    BACKGROUND: ClinicalTrials.gov identifier, NCT03380026.

    BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) drugs have never been associated with erythrocytosis. In Eritrea, however, several cases of incident erythrocytosis had been observed in the MDR-TB hospital. This study was aimed at exploring the association between MDR-TB drugs and secondary erythrocytosis, characterising the cases, and identifying other possible risk factors.
    METHODS: A retrospective cohort study was conducted in Merhano National Referral MDR-TB hospital. Data were extracted from physically available clinical cards and laboratory results collected longitudinally between 23 June 2011 and 17 January 2021. Initially, univariate descriptive statistics (frequency, mean (SD), median (IQR) and range) were used as appropriate. Then, χ2 or Fisher χ2 test, and bivariate and/or multivariate Cox proportional hazard model were used to identify the predictors of incident erythrocytosis. All statistical analyses were conducted using R, and a two-sided alpha 0.05 was used to determine the statistical significance.
    RESULTS: A total of 257 patients\' medical cards were screened, and 219 were eligible for further analysis. The median age of the patients was 38 years (range: 13-90 years) and 54.8% were males. During the follow-up time, 31 (14.2%) patients developed secondary erythrocytosis yielding an incidence rate of 7.8 cases per 1000 person-months. On average, the median time to onset of the event was found to be 5-months (range: 1-24 months). Males were more likely to develop the event than females (adjusted HR=7.13, 95% CI=1.66 to 30.53), and as body weight increases by 1 kg, the likelihood of developing secondary erythrocytosis was found to increase by 7% (adjusted HR=1.07, 95% CI=1.03 to 1.10). Moreover, all cases of secondary erythrocytosis were found to be possibly associated with the MDR-TB drugs.
    CONCLUSIONS: The authors hypothesised that the incident erythrocytosis is possibly be associated with MDR-TB drugs, and further studies are required to substantiate this finding.

    OBJECTIVE: Treatment options for corticosteroid-refractory and/or high-grade checkpoint inhibitor (CPI)-induced cutaneous adverse events (CAEs) are limited; however, anecdotal reports of biologic therapies have been successful. We aim to characterize the appropriate treatment scenarios and safety and efficacy profiles of biologics used to treat patients with CPI-induced CAEs at a single institution.
    METHODS: This is a retrospective case series of patients from January 1st, 2015 to October 20th, 2020, with CPI-induced CAEs who were treated with biologics at a single cancer center. Patients were identified using institutional electronic medical record who underwent CPI therapy with subsequent CAEs that necessitated biologic therapy. Diagnostic criteria utilized for CAEs were based on documentation by four board-certified dermatologists, in combination with detailed chart reviews and pathology findings. Primary study outcome measurements include CAE response, tumor response, and adverse events during biologics treatment.
    RESULTS: We identified 17 patients who fit study criteria. Sixteen patients experienced some degree of CAE improvement on biologics, with 10 of 10 patients reaching CAE resolution at 6 months post biologics. Eight patients needed new systemic treatment post biologics treatment, while 9 patients received no further treatment or stayed on the CPI. Thirteen patients tolerated biologics well with no significant adverse events or blood abnormalities, with only 2 patients experiencing biologic dose delays.
    CONCLUSIONS: In our cohort, biologics appear to be extremely efficacious in the treatment of severe-grade and/or steroid refractory CAEs. They also appeared to be well-tolerated without overtly negative effects on tumor response. In patients with limited cancer treatment options and good tumor response to CPIs, biologics should be considered for severe-grade and/or refractory CAEs.

    Idiosyncratic drug-induced liver injury (DILI) is a rare adverse event. DILI caused by direct oral anticoagulants (DOACs) has been reported, however, data on the risk of DILI are limited. The aim of the study was to evaluate the frequency of DILI caused by oral anticoagulants (OACs) in a population-based setting.
    A computerized database search in The National Prescription Database was performed identifying all patients in Iceland who were prescribed OACs (rivaroxaban, apixaban, dabigatran, edoxaban or warfarin) in 2008-2017. Personal identification numbers of these patients were linked with a database containing laboratory results for all hospitals and most outpatient clinics in Iceland. A medical chart review was performed in all cases where onset of liver injury followed intake of OACs. Patients with other specific causes of liver injury were excluded. Causality assessment with the RUCAM method was undertaken in cases with suspected DILI.
    Three cases of suspected DILI were identified. In all cases, rivaroxaban was the implicated agent among patients prescribed this product (n = 3446). All were women with a hepatocellular type of liver injury. One patient developed a suspected drug-induced autoimmune hepatitis and was treated with corticosteroids. No cases of DILI in patients on warfarin (n = 9101), apixaban (n = 1903), dabigatran (n = 1335) and edoxaban (n = 34) were identified.
    Rivaroxaban was the only OAC associated with DILI during the 10-year study period. Approximately 1 in 1100 patients treated with rivaroxaban developed DILI. Other OACs were not associated with liver injury in this population-based study.

    New treatments are required for severe breathlessness in advanced disease. We conducted a randomised feasibility trial of mirtazapine over 28 days in adults with a modified medical research council breathlessness scale score ≥3. Sixty-four patients were randomised (409 screened), achieving our primary feasibility endpoint of recruitment. Most patients had COPD or interstitial lung disease; 52 (81%) completed the trial. There were no differences between placebo and mirtazapine in tolerability or safety, and blinding was maintained. Worst breathlessness ratings at day 28 (primary clinical activity endpoint) were, 7.1 (SD 2.3, placebo) and 6.3 (SD 1.8, mirtazapine). A phase III trial of mirtazapine is indicated. Trial registration: ISRCTN 32236160; European Clinical Trials Database (EudraCT no: 2015-004064-11).

    BACKGROUND: The predictors of readmission in Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) have not been characterized.
    OBJECTIVE: To determine the variables predictive of 30-day readmission after SJS/TEN hospitalization.
    METHODS: We performed a cross-sectional study of the 2010-2014 Nationwide Readmissions Database. Bivariate and multivariable logistic regression was used to evaluate associations of patient demographics, comorbidities, and hospital characteristics with readmission. Aggregate and per-readmission costs were calculated.
    RESULTS: There were 8837 index admissions with SJS/TEN reported; of these, 910 (10.3%) were readmitted, with diagnoses including systemic infection (22.0%), SJS/TEN (20.6%), and cutaneous infection (9.1%). Associated characteristics included age 45 to 64 years (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.43-2.49), Medicaid insurance (OR, 1.83; 95% CI, 1.48-2.27), and nonmetropolitan hospital admission (OR, 1.67; 95% CI, 1.31-2.13). Associated comorbidities included HIV/AIDS (OR, 2.48; 95% CI, 1.63-3.75), collagen vascular disease (OR, 2.38; 95% CI, 1.88-3.00), and metastatic cancer (OR, 2.16; 95% CI, 1.35-3.46). The median per-readmission cost was $10,019 (interquartile range, $4,788-$16,485).
    CONCLUSIONS: The Nationwide Readmissions Database lacks the ability to track the same patient across calendar years. The diagnostic code lacks specificity for hospitalizations <3 days.
    CONCLUSIONS: Thirty-day readmissions after SJS/TEN hospitalizations are common. Dedicated efforts to identify at-risk patients may improve peridischarge continuity.
