Utility of the GerdQ questionnaire in detecting gastroesophageal symptoms with RA patients.

Objective: Rheumatoid arthritis (RA) affects multiple organ systems, including the esophagus. Moreover, one of the major side effects of methotrexate (MTX) is gastrointestinal disorders, which are said to affect medication adherence. We investigated the rate of MTX use, dosage, and the use of glucocorticoids (GCs) and oral non-steroidal anti-inflammatory drugs (NSAIDs) in relation to gastroesophageal (GE) symptoms, and whether they influence RA disease activity.

Neutralizing the IL-7Rα limits injury in experimental ANCA-associated glomerulonephritis.

Background And Hypothesis: Increased T cell IL-7Rα signaling is associated with a poorer prognosis in ANCA-associated vasculitis. These studies examined the functional role of IL-7Rα (CD127) in experimental glomerulonephritis mediated by anti-MPO T cell autoimmunity. We hypothesized that T cells would express IL-7Rα in the kidney and that blocking the function of IL-7Rα, without cellular depletion, would be protective.

[Two Cases of Advanced Recurrent Breast Cancer with Severe Heart Failure Caused By Anthracycline].

Case 1: A 48-year-old woman, had right breast cancer with multiple liver metastases. Seven courses of paclitaxel plus bevacizumab were administered, but due to disease progression, 12 courses of FEC 75(total epirubicin 900 mg/m2)were administered. 2 months after the last FEC administration, the patient developed heart failure and died about 3 months later.

Deletion of Antigen-Presenting Cells in Lipopolysaccharide-Induced Acute Kidney Injury (AKI) Affects the Exacerbation and Repair in AKI.

The pathogenesis of acute kidney injury (AKI) is complex and involves various immune and inflammatory responses. Antigen-presenting cells such as macrophages and dendritic cells (DCs) were recently reported to have diverse functions in AKI depending on the pathogenesis and disease phase. Herein, we intraperitoneally administered liposomal clodronate (LC) to lipopoly-saccharide (LPS)-induced AKI model mice in order to deplete antigen-presenting cells (e.

U-KIM-1 as a predictor of treatment response in lupus nephritis.

Objective: Biomarkers of disease activity in lupus nephritis (LN) are in demand. This is because they may be useful in patients who are unable to undergo invasive kidney biopsy, as predictors of renal function, and for early detection of LN recurrence. The focus is on the measurement of urinary chemokines and cytokines, especially in urinary biomarkers, which are non-invasive and simple.

Usefulness of Interleukin-18 as a Diagnostic Biomarker to Differentiate Adult-Onset Still's Disease With/Without Macrophage Activation Syndrome From Other Secondary Hemophagocytic Lymphohistiocytosis in Adults.

Background: Interleukin (IL)-18 is markedly elevated in systemic inflammatory diseases that cause the 'cytokine storm' such as adult-onset Still's disease (AOSD) and hemophagocytic lymphohistiocytosis (HLH). The differences in IL-18 between AOSD and HLH, especially in adults, is uncertain. Macrophage activation syndrome (MAS), a form of secondary HLH, is often difficult to differentiate cases of AOSD that include MAS from other secondary HLH.

Takayasu's Arteritis Diagnosed in an Adolescent Patient with Crohn's Disease: Management of Biologicals.

We report a 14-year-old man with Crohn's disease (CD) who developed right upper arm pain while being treated with the anti-tumor necrosis factor (TNF)-alpha monoclonal antibody, infliximab. There were no symptoms suggestive of active CD, but the inflammatory response was high, and a contrast-enhanced CT showed the occlusion of the right brachial artery. We diagnosed the patient as having Takayasu's arteritis (TA) and started treatment with corticosteroids, then tapered off the steroids as the symptoms of TA resolved.

Effects of denosumab versus teriparatide in glucocorticoid-induced osteoporosis patients with prior bisphosphonate treatment.

Introduction: Osteoporosis is one of the serious adverse effects associated with glucocorticoid therapy. Although bisphosphonates have been used for glucocorticoid-induced osteoporosis (GIO), some patients have shown an inadequate response. In such cases, denosumab or teriparatide are used.

Signaling Rho-kinase mediates inflammation and apoptosis in T cells and renal tubules in cisplatin nephrotoxicity.

Nephrotoxicity is a frequent complication of cisplatin-induced chemotherapy, in which T cells are known to promote acute kidney injury (AKI). Apoptosis and necrosis of tubules and inflammatory events also contribute to the nephrotoxicity. A delineation of the mechanisms that underlie the inappropriate renal and tubular inflammation can thus provide important insights into potential therapies for cisplatin-induced AKI.

The pathological role of IL-18Rα in renal ischemia/reperfusion injury.

Interleukin (IL)-18 is a proinflammatory cytokine produced by leukocytes and parenchymal cells (eg, tubular epithelial cells (TECs), mesangial cells, and podocytes). IL-18 receptor (IL-18R) is expressed on these cells in the kidney during ischemia/reperfusion injury (IRI), but its role in this injury is unknown. Fas/Fas ligand (FasL) is also involved in the pathogenesis of renal IRI via tubular apoptosis.

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.

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.

[Early diagnosis of connective tissue disease-related pulmonary hypertension].

It is known that prognosis of pulmonary hypertension (PH), especially connective tissue disease related PH (CTD-PH), is serious. CTD-PH is caused by not only pulmonary arterial hypertension, but also interstitial pneumonitis, hypoxia, chronic thromboembolism of pulmonary artery, or left heart diseases. Recently, prognosis of PH is improved by progress of diagnostic measures including echocardiography and development of effective vasodilators.

Successful treatment with retinoids in patients with lupus nephritis.

Lupus nephritis is a major manifestation of systemic lupus erythematosus. Treatment with such immunosuppressive agents as corticosteroids or cyclophosphamide can decrease the progression of lupus nephritis; however, these agents have potentially severe adverse reactions. Therefore, the development of new drugs with fewer side effects is needed.

Two cases of lupus cystitis with no bladder irritation symptoms.

Lupus cystitis is a rare manifestation in systemic lupus erythematosus (SLE); it usually occurs in association with gastrointestinal manifestations. We report two cases of lupus cystitis without bladder irritation symptoms. Both cases developed severe abdominal pain, nausea, and diarrhea and showed no bladder irritation symptoms.

Deletion of IL-18 receptor ameliorates renal injury in bovine serum albumin-induced glomerulonephritis.

Bovine serum albumin (BSA) glomerulonephritis is a type of immune complex glomerulonephritis that is characterized by a large number of leukocytes infiltrating the kidney. Interleukin (IL)-18, which has potent interferon (IFN)-gamma-inducing activities, may play an important role in lymphocyte-mediated inflammatory responses. To investigate the role of IL-18 in BSA glomerulonephritis, we used IL-18R-deficient C57BL/6 mice.

A case of adult onset Still's disease showing marked accumulation in the liver and spleen, on positron emission tomography-CT images.

A 35-year-old woman was admitted to our hospital because of high fever and skin rash, and subsequently diagnosed as having adult onset Still's disease (AOSD). Because of resistance to the steroid hormones, high levels of the serum-soluble form of the interleukin-2 receptor and splenomegaly, we suspected a possible diagnosis of malignant lymphoma and performed positron emission tomography (PET), which disclosed an intense accumulation of 2-deoxy-2 [F18] fluoro-D-glucose (FDG) in the liver and spleen. However, bone marrow aspiration and liver biopsy did not reveal any malignant cells.

Olopatadine suppresses the migration of THP-1 monocytes induced by S100A12 protein.

Olopatadine hydrochloride (olopatadine) is an antiallergic drug with histamine H(1) receptor antagonistic activity. Recently, olopatadine has been shown to bind to S100A12 which is a member of the S100 family of calcium-binding proteins, and exerts multiple proinflammatory activities including chemotaxis for monocytes and neutrophils. In this study, we examined the possibility that the interaction of olopatadine with S100A12 inhibits the proinflammatory effects of S100A12.
