Safety And Efficacy Of Dupilumab In Adult Patients With A History Of Eczema Herpeticum
Eczema herpeticum is not uncommon in patients with severe eczema. Prior studies have showed an increase rate of some herpes simplex exacerbation (oral ulcers) in retrospective analysis of patients treated with dupilumab versus placebo but no increase in eczema herpeticum. Efficacy and side effects of dupilumab, recently FDA approved for severe eczema, have not been reported in patients with a prior history of eczema

Ankyrin repeat domain 1 regulates innate immune responses against herpes simplex virus 1: A  potential role in eczema herpeticum
Atopic dermatitis (AD) is a common inflammatory skin disease. A  subset of patients with AD are susceptible to disseminated herpes simplex virus (HSV) infection, a complication termed eczema herpeticum (ADEH+). The immune mechanisms causing ADEH+ remain elusive. Using RNA sequencing, we recently found that ankyrin repeat domain 1 (ANKRD1) was significantly ind uced in human PBMCs upon HSV-1 stimulation, and its induction in patients with ADEH+ was significantly reduced compared with that seen in AD patients without a history of eczema herpeticum (ADEH−).

ANKRD1 regulates innate immune responses against herpes simplex virus 1: A potential role in eczema herpeticum
Atopic dermatitis (AD) is a common inflammatory skin disease. A subset of AD is susceptible to disseminated herpes simplex virus (HSV) infection, a complication termed as eczema herpeticum(ADEH+). The immune mechanisms causing ADEH+ remain elusive. Using RNA-sequencing, we recently found that ankyrin repeat domain 1 (ANKRD1) was significantly induced in human peripheral blood mononuclear cells (PBMCs) upon HSV-1 stimulation; and its induction in ADEH+ was significantly reduced as compared to AD patients without a history of EH (ADEH-).

Current Perspectives on Erythema Multiforme
AbstractRecognition and timely adequate treatment of erythema multiforme remain a major challenge. In this review, current diagnostic guidelines, potential pitfalls, and modern/novel treatment options are summarized with the aim to help clinicians with diagnostic and therapeutic decision-making. The diagnosis of erythema multiforme, that has an acute, self-limiting course, is based on its typical clinical picture of targetoid erythematous lesions with predominant acral localization as well as histological findings. Clinically, erythema multiforme can be differentiated into isolated cutaneous and combined mucocutaneous form...

Dermatological Complications After Solid Organ Transplantation
AbstractOrgan transplant recipients (OTRs) are a population at high risk for cutaneous adverse events. Their early recognition and appropriate treatment is an important component of the clinical management of OTRs and should be optimally dealt with by dermatologists working in the context of a transplant dermatology clinic. Skin examination should be a standard procedure before performing organ transplantation to assess conditions which may be difficult to manage after the transplant procedure has been performed or which may represent a contraindication to transplantation, e.g., malignant melanoma. It also offers an opport...

Patients with atopic dermatitis and history of eczema herpeticum elicit herpes simplex virus –specific type 2 immune responses
Atopic dermatitis (AD) is an inflammatory, relapsing skin disorder that affects 15% to 25% of children worldwide and persists in adulthood in around 25% of these cases.1 About 3% to 8% of patients with AD seem to have a disturbance in viral clearance, manifesting severe forms of molluscum contagiosum, papilloma virus, and most prominently, the generalized cutaneous infection with herpes simplex virus 1 (HSV1), called eczema herpeticum (EH),2,E1,E2 which can lead to life-threatening complications.

Patients with atopic dermatitis and history of eczema herpeticum elicit HSV-specific type 2 immune responses
An increased type 2 and in parallel decreased type 1 T cell immune response to herpes simplex virus 1 may lead to the clinical phenotype of eczema herpeticum.

How Common Is Hereditary Angioedema?
Discussion Angioedema is edema that is non-pitting, self-limited occurring in non-dependent areas usually in an asymmetric distribution usually on the lips, face, hands, feet, genitals and also in the bowel. It usually develops over minutes to hours (often 1-2 hours) with resolution usually within 24-48 hours. Angioedema often occurs with urticaria but 20% of patients may have isolated angioedema. Acute allergic angioedema is often caused by drugs (including antibiotics and non-steroidal anti-inflammatory drugs), foods, infections, insects, various organic substances (i.e. latex, preservatives, formaldehyde, etc.), and oth...

Herpes labialis: An Update.
CONCLUSION: For episodic treatment, oral antiviral agents, such as acyclovir (Zovirax), valacyclovir (Valtrex) and famciclovir (Famvir), are superior to topical antiviral therapy. Valacyclovir and famciclovir have greater oral bioavailability and are better absorbed than acyclovir, require less frequent dosing, but are more expensive and are not approved for children. Topical antiviral agents such as 5% acyclovir cream/ointment (Zovirax) ± hydrocortisone (Xerese), 1% penciclovir (Denavir) cream, and 50 mg Buccal Adhesive Tablet (ABT-50 mg) can also be used for episodic treatment of herpes labialis. These topical agents ar...

Differences in health-related quality of life between HIV-positive and HIV-negative people in Zambia and South Africa: a cross-sectional baseline survey of the HPTN 071 (PopART) trial

However, little is known about how these populations compare in terms of health-related quality of life (HRQoL). We aimed to compare HRQoL betwee...

CD4 T cell –restricted IL-2 signaling defect in a patient with a novel IFNGR1 deficiency
A female child was referred to our institution at age 20  months after a protracted course of a febrile illness and cough associated with radiographic findings, demonstrating a large necrotic suprahilar lymph node impinging on the right main stem bronchus. Culture of the lymph node biopsy specimen, blood, and sputum identified Mycobacterium fortuitum an d Mycobacterium avium complex, whereas bronchoalveolar lavage specimen culture revealed the presence of Moraxella species. Other clinical findings included severe eczema for the first 6 months of life that was controlled by emollient use, development of chicken pox after...

Relationship between glucocorticoid dose and adverse events in systemic lupus erythematosus: data from a randomized clinical trial.
CONCLUSION: This study highlights the feasibility of post-hoc analyses of RCTs using the SHARE mechanism and demonstrates the association of GCs with various AEs. Contrary to expectations, there were also associations between lower cumulative GC dose and several other AEs. PMID: 28862513 [PubMed - as supplied by publisher]

NIAID herpesvirus study in mice leads to discovery of potential broad-spectrum antiviral
(NIH/National Institute of Allergy and Infectious Diseases) NIAID scientists studying herpes simplex virus infection have unexpectedly found that inhibiting a cellular enzyme complex, EZH2/1, suppresses viral infection. The researchers then demonstrated that EZH2/1 inhibitors also enhanced the cellular antiviral response in cultured cells and mice. They then showed that EZH2/1 inhibitors suppressed HSV infection, spread, and reactivation in mice and, in cell culture, suppressed human cytomegalovirus, adenovirus, and Zika virus infections. They suggest that EZH2/1 inhibitors have considerable potential as broad-spectrum antivirals.
