Prediction of therapeutic responses with ultrasonography in RA patients treated with an anti-TNF drug: a retrospective cohort study.

Objective: Ultrasound (US) is more sensitive and reliable than a clinical examination, and is better correlated with the disease activity in rheumatoid arthritis (RA). We conducted the present study to assess the value of US as a screening tool to predict therapeutic responses in RA patients treated with anti-tumor necrosis factor (TNF) drugs.

Methods: We retrospectively analyzed the cases of 86 consecutive RA patients who were classified by their DAS28-CRP scores at the 54th week.

Infliximab dose adjustment can improve the clinical and radiographic outcomes of rheumatoid arthritis patients: REVIVE study results.

Purpose: We evaluated the clinical responses and radiographic outcomes of 90 patients with rheumatoid arthritis (RA) undergoing continuous or dose-adjusted infliximab treatment over 104 weeks.

Patients And Methods: Patients received 3 mg/kg infliximab continuously (the contin group; n=50), or the dose escalation and de-escalation of infliximab (3, 6, and 10 mg/kg) from week 14 (the adjusted group; n=40) based on the patient's Disease Activity Score in 28 joints (DAS28). The retention rate, clinical response, and radiographic assessment were determined at week 104.

Lipopolysaccharide-Induced Acute Kidney Injury Is Dependent on an IL-18 Receptor Signaling Pathway.

The proinflammatory cytokine interleukin (IL)-18 is an important mediator of the organ failure induced by endotoxemia. IL-18 (known as an interferon-gamma (IFN-γ) inducing factor), and other inflammatory cytokines have important roles in lipopolysaccharide (LPS)-induced acute kidney injury (AKI). We investigated the effect of inflammatory cytokines and Toll-like receptor 4 (TLR4) expression, an event that is accompanied by an influx of monocytes, including CD4⁺ T cells and antigen-presenting cells (APCs) in IL-18Rα knockout (KO) mice and wild-type (WT) mice after LPS injection.

Signaling through the interleukin-18 receptor α attenuates inflammation in cisplatin-induced acute kidney injury.

Interleukin (IL)-18 is produced by leukocytes and renal parenchymal cells (tubular epithelial cells, podocytes, and mesangial cells). The IL-18 receptor (IL-18R) is expressed on these cells in cisplatin-induced acute kidney injury, but the role of IL-18R is unknown. To help define this, we compared IL-18Rα knockout with wild-type mice in cisplatin-induced acute kidney injury and found deteriorated kidney function, tubular damage, increased accumulation of leukocytes (CD4(+) and CD8(+) T-cells, macrophages, and neutrophils), upregulation of early kidney injury biomarkers (serum TNF, urinary IL-18, and KIM-1 levels), and increased expression of pro-inflammatory molecules downstream of IL-18.

Therapeutic effect of retinoic acid on unilateral ureteral obstruction model.

Background: Retinoic acids, a group of natural and synthetic vitamin A derivatives, have potent anti-proliferative, anti-inflammatory and anti-fibrotic properties. We investigated the therapeutic effect of all-trans-retinoic acid (ATRA) on unilateral ureteral obstruction (UUO) model mice.

Methods: First, to evaluate the prophylactic effect, we administered 0.

[Remarkable improvement of the hip joint lesion in a patient with rheumatoid arthritis by the treatment with anti-TNF-α agents].

22-year old woman who was previously diagnosed as having juvenile idiopathic arthritis (JIA) was treated with anti-TNF-α agents. Her disease activity was assessed as Stage IV and Class III by Steinbrocker's classification and resistant to steroids and methotrexate. Initially clinical findings responded well to infliximab (IFX), but polyarthritis recurred 15 months after the start of the treatment, and IFX was switched to etanercept (ETN) with good response.

Therapeutic strategy and significance of serum rheumatoid factor in patients with rheumatoid arthritis during infliximab treatment.

To predict the response of patients with rheumatoid arthritis (RA) to infliximab, patient profile and laboratory findings were compared to determine whether there was any association with the clinical course of the disease, and the clinical significance of serum rheumatoid factor (RF) in the response to this treatment was considered. Sixty-two RA patients were treated with infliximab, 87.9% of whom were positive for RF.

Effect of combining ACE inhibitor and statin in lupus-prone mice.

MRL-Fas(lpr) mice spontaneously develop a systemic autoimmune disease resembling human systemic lupus erythematosus. The glomerulonephritis in MRL-Fas(lpr) mice is mediated by autoantibodies and autoreactive lymphocytes. To investigate the effect of combination therapy by angiotensin-converting enzyme inhibitor (ACEI) and hydroxymethylglutaryl-coenzyme A reductase inhibitor (statin) for lupus nephritis, we treated MRL-Fas(lpr) mice with imidapril, pravastatin or both agents.

VNCOP-B plus rituximab therapy in elderly patients with aggressive B-cell non-Hodgkin lymphoma: a multicenter experience.

CHOP (cyclophosphamide, adriamycin, vincristine, and prednisolone) plus rituximab is a standard chemotherapy used to treat patients with aggressive B-cell non-Hodgkin lymphoma (B-NHL). However, among elderly patients, this regimen has not been completely satisfactory in its efficacy and safety. We report our clinical experience in 8 collaborative institutions to determine if the VNCOP-B (etoposide, mitoxantrone, cyclophosphamide, vincristine, prednisolone, and bleomycin) combination therapy plus rituximab was effective and safe to treat elderly patients with aggressive B-NHL.

A case of Behcet's disease in a patient with albinism.

A 22-year old female suffering from recurrent oral ulcers, genital ulcers, erythema nodosum, and folliculitis, was diagnosed as having Behcet's disease (BD). She has also hypopigmentation of skin and hair, and optic changes associated with albinism including hypopigmentation of the retina, nystagmus, strabismus, and reduced visual acuity. In this report, we discuss the possibility of precipitating factor in BD that the hypersensitivity, mental stress, and drug resistance which is caused by albinism.

Successful treatment using tacrolimus plus corticosteroid in a patient with RA associated with MDS.

We report a case of rheumatoid arthritis (RA) complicated by myelodysplastic syndrome (MDS) successfully treated by tacrolimus. A 57-year-old woman had persistent pain and swelling in bilateral wrist and knee joints, in addition to severe anemia and leukopenia. She was diagnosed with MDS and RA based on the results of bone marrow aspiration and the criteria of RA.
