Chloroquine (CQ) and hydroxychloroquine (HCQ), two antimalarial drugs, are suggested to have potential anticancer properties. in the present study, we investigated the effects of CQ and HCQ on cell growth of bladder cancer with emphasis on autophagy inhibition and apoptosis induction in vitro. The results showed that CQ and HCQ inhibited the proliferation of multiple human bladder cell lines (including RT4, 5637, and T24) in a time- and dose-dependent fashion, especially in advanced bladder cancer cell lines (5637 and T24) compared to immortalized uroepithelial cells (SV-Huc-1) or other reference cancer cell lines (PC3 and MCF-7)...

OBJECTIVES: To study the prevalence of remission and its effect on damage and quality of life (QOL) in Chinese patients with systemic lupus erythematosus (SLE). METHODS: Patients who fulfilled≥4 American College of Rheumatology criteria for SLE were identified. Their remission status at last clinic visits was determined by the European consensus criteria (complete/clinical remission ± immunosuppressive drugs). The increase in SLE damage index (SDI) in the preceding 5 years was compared between patients who were and were not in remission for ≥5 years...

OBJECTIVES: The aim of this study was to characterise the use and costs of subsidising conventional disease-modifying anti-rheumatic drugs (DMARDs) and biologic DMARDs in Australia from 2004-2014 through pharmaceutical benefits schemes. METHODS: Dispensing and expenditure data on conventional and biologic DMARDs were extracted from Medicare Australia and temporal trends were analysed. Medicine use was standardised in terms of the defined daily dose (DDD) per 1,000 population per day (DDD/1,000 population/day)...

Background/purpose The objective of this study was to explore the impact of systemic lupus erythematosus and belimumab given in addition to standard of care therapy on 13-valent conjugated pneumococcal vaccine (PCV13) response. Methods Forty-seven systemic lupus erythematosus patients and 21 healthy controls were immunized with a single dose of 13-valent conjugated pneumococcal vaccine. Forty systemic lupus erythematosus patients were treated with traditional disease-modifying anti rheumatic drugs, 11 of those received belimumab in addition, and 32 patients were treated with concomitant prednisolone...

Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disease that can occur as a unique existence (primary Sjögren's syndrome) or merge with other systemic diseases like systemic lupus erythematosus (SLE), rheumatoid arthritis or systemic sclerosis (secondary Sjögren's syndrome). Data on the two diseases occurrence order are inadequate. Primary Sjögren's syndrome (pSS) may relatively uncommonly lead to diffuse cystic lung changes. We represent a female who was diagnosed pSS with diffuse cystic lung alterations developed SLE two years later...

OBJECTIVE: For patients with rheumatoid arthritis (RA) who have an inadequate response to methotrexate (MTX), the relative effectiveness of the combination of conventional disease-modifying antirheumatic drugs (DMARD) compared with the combination of tumor necrosis factor (TNF) inhibitors and MTX, as second-line therapy, is uncertain. The aim of this study was to compare the efficacy and tolerance of triple oral DMARD therapy versus anti-TNF agents associated with MTX in patients with RA after MTX failure...

BACKGROUND: Herein, we report a case of atypical periorificial dermatitis in a patient that had been receiving treatment for some time for atopic dermatitis. The specific feature of this rash was its periocular predominance with no perioral involvement, its clinical aspect and its histological picture evocative of sarcoidosis. PATIENTS AND METHODS: A 33-year-old man was being treated for a atopic dermatitis limited to the face and poorly responsive to dermal corticosteroids...

Targeting residual self-renewing, chemoresistant cancerous cells may represent the key to overcoming therapy resistance. The entry of these quiescent cells into an activated state is associated with high metabolic demand and autophagic flux. Therefore, modulating the autophagy pathway in aggressive carcinomas may be beneficial as a therapeutic modality. In this study, we evaluated the anti-tumor activities of 4-acetylantroquinonol B (4-AAQB) in chemoresistant ovarian cancer cells, particularly its ability to modulate autophagy through autophagy-related genes (Atg)...

Hydroxychloroquine is an oral antimalarial medication commonly used off-label for a variety of rheumatological conditions, including systemic lupus erythematosus, rheumatoid arthritis, Sjögren's syndrome and dermatomyositis. We present a case of a 64-year-old woman who presented with acute onset headache, bilateral tinnitus, and left-sided facial numbness and tingling in the setting of accidentally overdosing on hydroxychloroquine. By the next morning, the patient began to experience worsening in the tingling sensation and it eventually spread to her left arm, thigh and distal extremities...

Macroautophagy and chaperone-mediated autophagy (CMA) represent two major lysosomal degradation processes and often compensate for one another to facilitate cell survival. The aim of this study was to determine whether these autophagy pathways could compensate for one another to promote HCC cell survival in the cirrhotic liver. Analysis of normal liver tissue showed no expression of glypican-3 or p62 proteins, suggesting that macroautophagy is the major contributor to autophagic flux under non-pathological conditions...

A novel technique for collection of capillary blood, termed volumetric absorptive microsampling (VAMS), has been recently cleared by the FDA for collection of human blood. VAMS absorbs a fixed volume of blood (10μl) and overcomes area bias and homogeneity issues associated with dried blood spot (DBS). This study is the application of VAMS for therapeutic drug monitoring (TDM) in human capillary blood. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) workflow for analysis of VAMS sample was developed and validated...

OBJECTIVE: Although it is common for rheumatologists to initiate biologics after failure of methotrexate monotherapy in rheumatoid arthritis (RA), ample data supports the initial use of combinations of conventional therapies in this clinical scenario. Our study explores the durability of triple therapy (methotrexate, sulfasalazine, and hydroxychloroquine) versus methotrexate-etanercept in RA. METHODS: RA patients with suboptimal response to methotrexate (n = 353) were randomized to either triple therapy or methotrexate-etanercept therapy in a 48-week, double-blinded, non-inferiority trial...

CLIPPERS for chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids, is a steroid-sensitive and steroid-dependent brainstem inflammatory disease of unknown origin. Since its first description in 2010, about 60 cases have been reported throughout the world. The mean age at onset is 50 years and men seem to be more frequently affected. In patients without chronic corticosteroid therapy or immunosuppressive agents, the disease had a relapsing remitting course, and the mean annualized relapse rate was 0...

OBJECTIVE: Ovarian clear cell carcinoma (CCC) is one of histological subtypes showing poor prognosis due to chemoresistance. The association of autophagy-related proteins and clinical implementation in CCC has not been determined. METHODS: The present study investigated whether expression of autophagy-related protein, light chain 3A (LC3A), was related with prognoses in the patients with CCC using immuno-histochemical stainings, and whether inhibition of autophagy modified the sensitivity to cisplatin in CCC cells in vitro...

BACKGROUND: New targeted therapies and improved treatment strategies have dramatically improved the outcomes of patients with rheumatoid arthritis (RA). However, it is unknown whether different early aggressive interventions can induce stable remission or a low-active disease state that can be maintained with conventional synthetic disease-modifying antirheumatic drug (csDMARD) therapy, and whether they differ in efficacy and safety. The Nordic Rheumatic Diseases Strategy Trials And Registries (NORD-STAR) study will assess and compare (1) the proportion of patients who achieve remission in a head-to-head comparison between csDMARD plus glucocorticoid therapy and three different biological DMARD (bDMARD) therapies with different modes of action and (2) two de-escalation strategies in patients who respond to first-line therapy...
