Raymond Fertig, Antonella Tosti
Frontal fibrosing alopecia (FFA) is a rare dermatologic disease that causes scarring and hair loss and is increasing in prevalence worldwide. FFA patients typically present with hair loss in the frontal scalp region and eyebrows which may be associated with sensations of itching or burning. FFA is a clinically distinct variant of lichen planopilaris (LPP) that affects predominantly postmenopausal women, although men and premenopausal women may also be affected. Early diagnosis and prompt treatment are necessary to prevent definitive scarring and permanent hair loss...

Atopic dermatitis (AD) is a common, chronic childhood skin disorder caused by complex genetic, immunological, and environmental interactions. It significantly impairs quality of life for both child and family. Treatment is complex and must be tailored to the individual taking into account personal, social, and emotional factors, as well as disease severity. This review covers the management of AD in children with topical treatments, focusing on: education and empowerment of patients and caregivers, avoidance of trigger factors, repair and maintenance of the skin barrier by correct use of emollients, control of inflammation with topical corticosteroids and calcineurin inhibitors, minimizing infection, and the use of bandages and body suits...

INTRODUCTION: Calcineurin inhibitor nephrotoxicity is major problem after organ transplantation. It is multifactorial, but oxidative stress may have an important role in this process. It has been shown that angiotensin II receptor blockers have renoprotective effects but their molecular mechanism is largely unknown. Antioxidative effect is an important role of the recently known anti-aging protein, klotho. This study aimed to evaluate effect of valsartan in alleviation of cyclosporine A nephrotoxicity via a probable increase in serum klotho levels or decreasing oxidative stress...

BACKGROUND&AIMS: Most of the specific inhibitors of hepatitis B virus (HBV) entry, including myrcludex-B and cyclosporin A (CsA), target an HBV entry receptor, sodium taurocholate cotransporting polypeptide (NTCP). As all these agents have capacities to impair the NTCP transporter activity for bile acid uptake and thus may cause significant adverse effects, we aim to identify small molecules that inhibit HBV entry but least affecting the NTCP transporter function. METHODS: We focused on derivatives of CsA, which originally inhibited both HBV entry and NTCP-mediated bile acid uptake, to analyze the possibility to distinguish these two activities...

BACKGROUND: In a phase 2 study, kidney transplant recipients of low immunologic risk who switched from a calcineurin inhibitor (CNI) to belatacept had improved kidney function at 12 months postconversion versus those continuing CNI therapy, with a low rate of acute rejection and no transplant loss. STUDY DESIGN: 36-month follow-up of the intention-to-treat population. SETTING & PARTICIPANTS: CNI-treated adult kidney transplant recipients with stable transplant function (estimated glomerular filtration rate [eGFR], 35-75mL/min/1...

Costimulation blockade (CoB) via belatacept is a lower morbidity alternative to calcineurin inhibitor (CNI)-based immunosuppression. However, it has higher rates of early acute rejection. These early rejections are mediated in part by memory T cells, which have reduced dependence on the pathway targeted by belatacept, and increased adhesion molecule expression. One such molecule is Leukocyte Function Associated Antigen (LFA)-1. LFA-1 exists in two forms, a commonly expressed, low-affinity form, and a transient, high-affinity form, expressed only during activation...

Allergic contact dermatitis (ACD) is a common skin disease caused by a T cell-mediated immune reaction to usually innocuous allergens. ACD can have grave medical and socioeconomic consequences. ACD and irritant contact dermatitis often occur together. A detailed history and clinical examination are crucial and guide patch testing, which is the gold standard to diagnose ACD. T-cell clones persisting in the skin may explain the tendency of ACD to relapse even after years of allergen avoidance. Traditional treatments for ACD are topical steroids, calcineurin inhibitors, phototherapy, retinoids (including the recent alitretinoin), and immunosuppressants...

BACKGROUND: -Kawasaki disease (KD) is an acute pediatric vasculitis in which host genetics influence both susceptibility to KD and the formation of coronary artery aneurysms. Variants discovered by genome-wide association studies (GWAS) and linkage studies only partially explain the influence of genetics on KD susceptibility. METHODS AND RESULTS: -To search for additional functional genetic variation, we performed pathway and gene stability analysis on a GWAS dataset...

Because calcineurin inhibitor immunosuppressive drugs (CNIs) induce arteriolar hyalinosis (ah) in kidney transplants, ah lesions can potentially provide information about drug exposure. We studied the relationship of ah lesions to findings and outcomes in 562 indication biopsies taken 3 days to 35 years post-transplant. Prevalence of ah lesions increased with time post-transplant (TxBx). Ah-scores correlated with arterial intimal thickening and atrophy-fibrosis but, unlike atrophy-fibrosis, did not increase until after 500 days because of a background of ah1 lesions in early biopsies reflecting donor aging...

Preclinical changes that precede the onset of symptoms and eventual diagnosis of Alzheimer's disease (AD) are a target for potential preventive interventions. A large body of evidence suggests that inflammation is closely associated with AD pathogenesis and may be a promising target pathway for such interventions. However, little is known about the association between systemic inflammation and preclinical AD pathophysiology. We first examined whether the acute-phase protein, alpha-2 macroglobulin (A2M), a major component of the innate immune system, was associated with cerebrospinal fluid (CSF) markers of neuronal injury in preclinical AD and risk of incident AD in the predictors of cognitive decline among normal individuals (BIOCARD) cohort...

Gap junctional intercellular communication (GJIC) has been suggested to be involved in early embryonic development but the actual functional role remained elusive. Connexin (Cx) 43 and Cx45 are co-expressed in embryonic stem (ES) cells, form gap junctions and are considered to exhibit adhesive function and/or to contribute to the establishment of defined communication compartments. Here we describe the generation of Cx43/Cx45-double deficient mouse ES cells to achieve almost complete breakdown of GJIC. Cre-loxP induced deletion of both, Cx43 and Cx45, results in a block of differentiation in embryoid bodies without affecting pluripotency marker expression and proliferation in ES cells...

Nearly 31,000 US patients received solid organ transplants in 2015 and the number is increasing. Care of transplant recipients includes management of a variety of common posttransplantation issues. Skin cancers are common because of immunosuppression and require skin examinations at intervals. Patients should be educated about the need to report new skin lesions. The rates of other cancers also are increased, including cancers of the head and neck, lung, esophagus, cervix, and urinary tract. Osteoporosis is common in transplant recipients; monitoring and early therapy are important...

L-type Ca(2+) currents conducted by voltage-gated calcium channel 1.2 (CaV1.2) initiate excitation-contraction coupling in the heart, and altered expression of CaV1.2 causes heart failure in mice. Here we show unexpectedly that reducing β-adrenergic regulation of CaV1.2 channels by mutation of a single PKA site, Ser1700, in the proximal C-terminal domain causes reduced contractile function, cardiac hypertrophy, and heart failure without changes in expression, localization, or function of the CaV1.2 protein in the mutant mice (SA mice)...

The aim of the present study was to analyze in vivo the role of SNAI1 on renal fibrosis. Unilateral ureteral obstruction injury was induced in Snai1 knockout mice. Snai1 gene deletion was, however, only partial and could therefore not be correlated to reduced fibrosis. Expression of SNAI1 protein and epithelial-mesenchymal transformation markers was then assessed in human chronic allograft nephropathy biopsy specimens. Significant up-regulation of SNAI1 protein was detected within cytoplasm of proximal tubules localized, for some of them, near foci of fibrosis and tubular atrophy...

Calcineurin inhibitors (CNI) are the mainstay of immunosuppression after liver transplantation (LT), but CNIs are associated with significant nephrotoxicity. Recently, mTOR inhibitors such as sirolimus and everolimus (EVR) have been used with or without CNIs in LT recipients for their renal-sparing effect. We conducted a systematic review and meta-analysis of randomized controlled trials (RCT) that examined the effect of EVR with CNI minimization or withdrawal on renal function in LT recipients. RCT of primary adult LT recipients with baseline GFR >30 mL/min who received EVR with CNI minimization or withdrawal were included...

BACKGROUND: Calcineurin inhibitors (CNIs) and direct oral anticoagulants (DOACs) share certain metabolic pathways, but whether DOACs influence CNI exposure has not been assessed. METHODS: A single-center retrospective analysis was performed including 39 organ recipients treated with the combination of a CNI and rivaroxaban (n = 29) or apixaban (n = 10). Dose-corrected CNI trough concentrations (C0/D) during 200 days before and after DOAC initiation were recorded (n = 261), together with covariates known to influence CNI disposition such as steroid dose and hematocrit...

BACKGROUND: Blockade of CD28-mediated T cell costimulation by a modified cytotoxic T lymphocyte-associated antigen 4 (CTLA4-Ig), belatacept, is a clinically effective immunosuppressive therapy for the prevention of renal allograft rejection. Use of belatacept-based calcineurin inhibitor-free immunosuppression, however, has demonstrated an increased frequency of cellular rejection episodes and immunosuppression-related safety issues relative to conventional regimens. Furthermore, belatacept typically requires infusion for its administration chronically, which may present an inconvenience to patients...

Solid-organ transplant recipients are at increased risk of developing de novo malignancies compared with the general population, and malignancies become a major limitation in achieving optimal outcomes. The prevention and the management of posttransplant malignancies must be considered as a main goal in our transplant programs. For these patients, immunosuppression plays a major role in oncogenesis by both impairement of immunosurveillance, enhancement of chronic viral infection, and by direct prooncogenic effects...

Cutaneous lupus erythematosus (CLE) is a rare inflammatory autoimmune disease with heterogeneous subtypes. To date, no therapeutic agents have been licensed specifically for patients with this disease entity and topical and systemic drugs are mostly used "off-label". The aim of the present guideline was to achieve a broad consensus on treatment strategies for patients with CLE by a European subcommittee, guided by the European Dermatology Forum (EDF) and supported by the European Academy of Dermatology and Venereology (EADV)...
