This study investigated the effects and mechanism of esculetin (6,7-dihydroxycoumarin) on non-alcoholic fatty liver in diabetic mice fed high-fat diet (HFD). The diabetic mice model was induced by injection of streptozotocin, after which they were fed HFD diet with or without esculetin for 11 weeks. Non-diabetic mice were provided a normal diet. Diabetes induced hepatic hypertrophy, lipid accumulation and droplets; however, esculetin reversed these changes. Esculetin treatment in diabetic mice fed HFD significantly down-regulated expression of lipid synthesis genes (Fasn, Dgat2 and Pap) and inflammation genes (Tlr4, Myd88, Nfkb, Tnfα and Il6)...

INTRODUCTION: Pegloticase is a highly effective therapy for patients with refractory and/or tophaceous gout, but has a high discontinuation rate (30-50%) due to development of anti-drug antibodies causing loss of efficacy and risk of infusion reactions. OBJECTIVE: To describe the use of azathioprine or other immunosuppressive therapies as a pegloticase adjunct to prevent pegloticase immunogenicity when treating gout. METHODS: Case report of azathioprine use in a patient receiving pegloticase therapy for refractory tophaceous gout, and review of the literature for the impact of immunosuppressive agents on development of anti-drug antibodies...

BACKGROUND AND OBJECTIVES: Recently, the osteoporosis treatment has attracted attention, and several drugs have been developed. Among these, bisphosphonates (BPs), parathyroid hormone (PTH) and anti-receptor activator of nuclear factor kappa B ligand (RANKL) monoclonal (MAb) denosumab (DMAb) are the major osteoporosis agents. Several studies demonstrated that the effect of osteoporosis agents is evaluated by lumar or hip dual energy X-ray absorptiometry (DXA). However, private clinic commonly use the radial DXA...

Choline alfoscerate (α-GPC) is a common choline compound and acetylcholine precursor in the brain, which has been shown to be effective in the treatment of Alzheimer's disease and dementia. α-GPC has been shown to enhance memory and cognitive function in stroke and Alzheimer's patients but currently remains untested in patients suffering from epilepsy. This study aimed to evaluate whether α-GPC treatment after seizure can ameliorate seizure-induced cognitive impairment and neuronal injury. The potential therapeutic effects of α-GPC on seizure-induced cognitive impairment were tested in an animal model of pilocarpine-induced seizure...

Impaired apoptosis of fibroblast-like synoviocytes (FLSs) causes synovial hyperplasia, facilitating destruction of cartilage and bone in rheumatoid arthritis (RA). Tumor necrosis factor (TNF)-α, a dominant inflammatory mediator in RA pathogenesis, promotes progression of RA symptoms. Prevalence of 1, 25-dihydroxy-vitamin D3 (hereafter termed VD) deficiency is 30-63% in patients with RA. Whether VD leads to apoptosis or enhances TNF-α-mediated apoptosis in FLSs to ameliorate RA is unclear. To determine this, 10-week-old CYP27B1-deficient (CYP27B1(-/-)) mice with collagen-induced arthritis (CIA) were intraperitoneally treated with 1 μg/kg VD every other day for 9 weeks...

RAPID3 (routine assessment of patient index data) is an index found within a multi-dimensional health assessment questionnaire (MDHAQ) for routine clinical care, composed only of 3 self-report scores for physical function, pain, and patient global estimate, each scored 0-10, for a total of 0-30. RAPID3 is correlated significantly with DAS28 (Disease Activity Score) and CDAI (Clinical Disease Activity Index), and distinguishes active from control treatments as efficiently as these indices in clinical trials involving adalimumab, abatacept, certolizumab, infliximab, and rituximab...

OBJECTIVES: Electronic platforms have been developed to help the clinician monitor disease activity in rheumatoid arthritis (RA) to support at treat-to-target strategy. We present an initiative to interactively improve disease control in patients with rheumatoid arthritis. METHODS: In patients who presented with one or more swollen joints AND moderate/high disease activity (i.e. either CDAI≥10.1 and/or DAS-28CRP>3.2, which is automatically calculated in the DANBIO registry), a red alert was shown, which activated a pop-up: "This patient has at least one swollen joint AND either CDAI≥ 10...

Disease activity assessment of rheumatoid arthritis has never been trivial. Composite indices like the Disease Activity Score using 28 joint counts 28 (DAS28) and the Clinical Disease Activity Index (CDAI) and the Simplified Disease Activity Index (SDAI) attempted to integrate several core set variables into one readout, which eventually laid the grounds for implementation strategies that targeted disease activity levels, like remission. While CDAI and SDAI were clearly simpler at times when a calculator was needed, this has likely become less relevant in the era of digital records, where core set variables are entered into a computed device after measurement...

: The progression of the inflammatory process in the course of rheumatoid arthiritis (RA) may cause a permanent destruction of joints, which in case of bigger ones (i.e. hip or knee) may be particularly a psychological burden for a patient. AIM: The aim of the study was to verify whether implantation of hip or knee endoprosthesis affect anxiety and depressive symptoms among patients with RA. MATERIALS AND METHODS: The study enrolled a group of 128 rheumatoid arthritis patients, including 64 patients before and 64 patients after the joint replacement procedure...

Microsomal prostaglandin E2 synthase-1 (mPGES-1) constitutes an essential player of inflammation and is involved in the pathogenesis of rheumatoid arthritis (RA). Platelets participate in the regulation of inflammatory processes by the release of pro-inflammatory mediators and platelet-derived microparticles (PMPs). However, the role of the inducible mPGES-1/PGE2 pathway on platelet functions has not been investigated. Here we report a significant impact of mPGES-1 on platelet functions during inflammation...

OBJECTIVE: The early diagnosis of rheumatoid arthritis (RA) is desirable to install treatment to prevent disease progression and joint destruction. Autoantibodies and immunological markers pre-date the onset of symptoms by years albeit not all patients will present these factors, even at disease onset. Additional biomarkers would be of high value to improve early diagnosis and understanding of the process, leading to disease development. METHODS: Plasma samples donated before the onset of RA were identified in the Biobank of Northern Sweden, a collection within national health survey programs...

OBJECTIVE: A failure of endovascular renal denervation (RDN) as a series of point treatments equally distributed within main trunk of renal artery (Symplicity and other methods) was easily predictable. It may only be effective if all renal nerves closely follow the course of renal artery (RA) from aorta to the kidney. However, surgical studies demonstrated that proximally most renal nerves go at a distance from RA and join mainly its distal part. To evaluate whether denervation treatment in distal part of RA is more effective than conventional RDN...

Osteoarthritis (OA) is the most common type of arthritis. To manage OA, in general, oral administration of non-steroidal anti-inflammatory drugs (NSAIDs) is used. Recently, the analgesic and anti-inflammatory efficacy of piroxicam (PX), a long-acting NSAID, by intra-articular (IA) administration in OA was reported, and the possibility that PX is distributed in articular tissues at a certain concentration was raised. Thus, herein, novel LC-MS/MS methods to detect PX in rat articular tissue and plasma are presented...
