Background There are different treatment options for ocular toxoplasmosis (OT). "Classic" therapy consists of pyrimethamine, sulfadiazine and folinic acid combined with systemic steroids and is still widely used. However, potentially severe side effects of this therapy have been reported. The aim of this retrospective study was to evaluate the incidence and types of adverse drug reactions in patients treated for OT. Clinical management of each adverse drug reaction was assessed. Patients and Methods In this retrospective analysis, we reviewed data of patients with OT, who were consecutively examined between December 2011 and December 2015 at the Department of Ophthalmology, University Hospital Zurich...

TNF-α-inhibitors are known to induce skin adverseeffects including psoriasis and alopecia areata. Here, wedescribe a unique pattern of hair loss that has psoriaticand alopecia areata-like features. Diagnosis requiresclinical-pathologic correlation and is supportedby increased catagen/telogen hairs, psoriasiformepidermal hyperplasia, perifollicular lymphocyticinfiltrate, and the presence of eosinophils and plasmacells. Although there are no treatment consensusguidelines, management options include stoppingtherapy, switching to a different TNF-α inhibitor orustekinumab (in severe cases), or continuing TNF-αinhibitor therapy with addition of topical, intralesional,or systemic immunosuppressants...

Background.: Ombitasvir/paritaprevir/ritonavir with dasabuvir (OBV/PTV/r + DSV) ± ribavirin (RBV) is approved for hepatitis C virus (HCV) genotype 1 (GT1) treatment in HIV-1 coinfected patients. In healthy controls, coadministration of OBV/PTV/r + DSV + darunavir (DRV) lowered DRV trough concentration (Ctrough) levels. To assess the clinical significance of this change, TURQUOISE-I, Part 1b, evaluated the efficacy and safety of OBV/PTV/r + DSV + RBV in coinfected patients on stable, DRV-containing antiretroviral therapy (ART)...

OBJECTIVE: Several factors, such as male gender, older age, type of insurance, comorbid conditions, and medication type, have been associated with attention-deficit/hyperactivity disorder (ADHD) medication adherence rates, but the results have been inconsistent. We analyzed data to answer several questions: 1) How old were patients who first refilled their treatment medications used primarily for ADHD, regardless of the medication type? 2) What socio-demographic factors are associated with medication adherence? 3) What medical conditions, such as medication type and comorbid diagnosis, influence adherence? METHODS: We analyzed National Health Insurance data, which comprised continuously enrolled Korean National Medical Insurance children (6-18 years) with at least 2 ADHD prescription claims (January 2008-December 2011)...

Clinical data have been equivocal and controversial as to the benefits to the brain and cognition of hormone therapy (HT) in postmenopausal women. Recent reevaluation of the role of estrogens proposed that HT may effectively prevent the deleterious effects of aging on cognition, and reduces the risks of dementia, including Alzheimer's disease, if initiated early at the beginning of menopause. Yet, little is known about the effects of HT on brain activation related to cognitive control, the ability to make flexible decisions in relation to internal goals...

Mycosis fungoides (MF) is characterized by a switch from indolent behaviour in the early stages to a worse clinical outcome in the advanced ones. Recently, various studies have investigated the role the microenvironment might play in such a switch. We have analysed the distribution of Langerhans cells, plasmacytoid dendritic cells and myeloid-derived suppressor cells in 46 MF cases in various stages, aiming to assess whether changes occur from early to advanced stage. We have investigated the number of langerin, CD303 and arginase-1 positive cells and their distribution at high power...

BACKGROUND: Approximately 75% of medical inpatients at Queen Elizabeth Central Hospital (QECH) in Blantyre, Malawi are HIV seropositive, and a third of these patients are on antiretroviral therapy (ART). Malawi guidelines recommend targeted viral load (VL) testing for patients on ART for at least one year who report excellent adherence and present with a WHO clinical stage 3 or 4 HIV disease. A switch to second-line ART is only indicated if a VL result >5000 copies/mL confirms treatment failure...

BACKGROUND: About 75-80% of breast tumors express the estrogen receptor alpha (ER-α) and are treated with endocrine-target therapeutics, making this the premier therapeutic modality in the breast cancer clinic. However, acquired resistance is common and about 20% of resistant tumors loose ER-α expression via unknown mechanisms. Inhibition of ER-α loss could improve endocrine therapeutic efficacy, benefiting a significant number of patients. Here we test whether tumor hypoxia might commonly produce ER-α loss...

Dimple Patel, K T Park
The advent of biosimilars in inflammatory bowel disease (IBD) represents an opportunity for cost-savings and increased patient access to effective disease-modifying therapies. While preliminary data in adult IBD and rheumatology patients suggest comparable effectiveness and pharmacokinetics between original biologics and biosimilars, long-term immunogenicity data are unknown. Without this data, conclusions about interchangeability should not be made for pediatric patients with IBD. Children affected by IBD, in particular, are a vulnerable group if automatic substitution and non-medical switching are allowed based on limited data in adult patients...

Primary membranous nephropathy (PMN) is characterized by antibodies to the podocyte, but little is known about B- and T-cell populations and their response to rituximab is controversial. To help resolve this we compared 33 lymphocyte subpopulations and 27 cytokines/chemokines in 25 patients with severe PMN and 27 age-matched healthy individuals. At baseline, patients had a significantly increased percentage of naive B-cells with significantly decreased switched and non-switched memory B-cells. There was a significantly decreased percentage of natural killer (NK) cells with an increase in the CD56(bright)CD16(-/lo) NK subset...

Studies of nephrotic syndrome show that substitution of calcineurin inhibitors by mycophenolate mofetil (MMF) enables sustained remission and corticosteroid sparing and avoids therapy associated adverse effects. However, controlled studies in patients with steroid resistance are lacking. Here we examined the effect of switching from therapy with tacrolimus to MMF on disease course in an open-label, one-to-one randomized, controlled trial on children (one to 18 years old), recently diagnosed with steroid-resistant nephrotic syndrome, at a referral center in India...

Ras GTPases act as "molecular switches", alternating between inactive GDP-bound and active GTP-bound conformation. Ras-oncogenes were discovered over three decades ago, but there are still no effective therapies for Ras-driven cancers. Drug discovery strategies have so far been unsuccessful, due to a lack of suitable screening methodologies and well-defined binding pockets on the Ras proteins. Here, we addressed the former by introducing a homogeneous quenching resonance energy transfer (QRET) technique based screening strategy for Ras interfacial and competitive inhibitors...

DEK is a highly conserved chromatin-bound protein whose upregulation across cancer types correlates with genotoxic therapy resistance. Loss of DEK induces genome instability and sensitizes cells to DNA double strand breaks (DSBs), suggesting defects in DNA repair. While these DEK-deficiency phenotypes were thought to arise from a moderate attenuation of non-homologous end joining (NHEJ) repair, the role of DEK in DNA repair remains incompletely understood. We present new evidence demonstrating the observed decrease in NHEJ is insufficient to impact immunoglobulin class switching in DEK knockout mice...

REVIEW
Indulekha Karunakaran, Gerhild van Echten-Deckert
The physiological functions of sphingosine 1-phosphate (S1P) and its pathological roles in various diseases are increasingly being elucidated. Particularly, a growing body of literature has implicated S1P in the pathogenesis of brain related disorders. With the deciphering of more intricate aspects of S1P signalling, there is also a need to reconsider the notion of S1P only as a determinant of cell survival and proliferation. Further the concept of 'S1P-ceramide' balance as the controlling switch of cellular fate and functions needs to be refined...
