This study assessed the efficacy of an Ammodaucus leucotrichus seed extract to treat rheumatoid arthritis in rat models of this disease. Rheumatoid arthritis was induced in rats using two methods: immunization with 100 µL of Complete Freund Adjuvant (CFA) and immunization with 100 µL of a 3 mg/ml solution of type II collagen (CII) from chicken cartilage. The therapeutic potential of the extract was assessed at different doses (150, 300, and 600 mg/kg/day for 21 days in the CII-induced arthritis model and for 14 days in the CFA-induced arthritis model) and compared with methotrexate (MTX; 0...

Autoimmune diseases can result in additional symptoms and complications impacting various organ systems beyond the joints. These can affect the eyes, skin, respiratory, cardiac, and renal systems. Recognizing and understanding these diverse manifestations, such as the severe eye issues seen in rheumatoid arthritis (RA) and the potentially life-threatening Felty syndrome, is crucial for clinicians to promptly identify and treat these conditions effectively. In this case presentation, we report on a patient admitted for bilateral scleritis, which was found to be secondary to multiple autoimmune syndrome type 3...

JAK/STAT pathway signalling is associated with both chronic inflammatory conditions such as psoriasis and haematological malignancies such as the myeloproliferative neoplasms (MPNs). Here we describe a 73yo female patient with a history of chronic plaque psoriasis, post-essential thrombocythemia myelofibrosis (MF) and a quality of life substantially impacted by both conditions. We report that 15 mg oral Methotrexate (MTX) weekly as a monotherapy is well tolerated, provides a substantial clinical improvement for both conditions and significantly improves quality of life...

OBJECTIVE: To investigate the metabolic changes during therapy of tocilizumab (TCZ) and methotrexate (MTX) in non-diabetic rheumatoid arthritis (RA) patients and for the first time explore the associations between metabolic parameters and serum YKL-40 (sYKL-40) levels. METHODS: We enrolled active non-diabetic RA patients who were refractory to MTX. Patients received intravenous TCZ (8 mg/kg) once every 4 weeks combined with MTX for 24 weeks. Metabolic parameters and sYKL-40 levels were measured before TCZ infusion at baseline, week 4, week 12, and week 24...

OBJECTIVE: Adult-onset Still's disease (AOSD) is a multigenic autoinflammatory disease with a severe systemic involvement. Because of the rarity of the disease, most published cohorts are multicentric. The aim of this report is to describe a monocentric cohort of AOSD patients, reporting clinical features and response to therapy in a long follow-up. METHOD: Thirty-eight patients, attending the Clinical Immunology Unit and fulfilling Yamaguchi, Fautrel, or Daghor-Abbaci classification criteria for AOSD, were recruited for this study...

INTRODUCTION AND IMPORTANCE: Brentuximab vedotin (BV) is an anti-CD30 antibody approved for various cancers, including refractory Hodgkin lymphoma (HL), anaplastic large-cell lymphoma (ALCL) among others. In general, BV has been found to be well-tolerated, with the most frequently reported side effects being peripheral neuropathy and neutropenia. BV-induced pneumonitis is extremely rare. To the best of our knowledge, this is the sixth reported instance of BV-induced lung toxicity. CASE PRESENTATION: This case presents a female patient in her forties diagnosed with cutaneous T-cell lymphoma undergoing BV treatment...

We report a case of septic arthritis in a 43-year-old female patient. Despite initial treatment with ceftriaxone for Nontyphoidal Salmonella based on blood and joint fluid culture results, the shoulder joint pain worsened. Suspected systemic lupus erythematosus associated synovitis did not respond to immunosuppressive therapy including methylprednisolone, hydroxychloroquine and methotrexate. Subsequent radiograph revealed a shoulder joint abscess, leading to arthroscopic joint debridement. Ceftriaxone was administered post-operatively until analgesic efficacy was attained...

Cancer of unknown primary (CUP) and leptomeningeal metastasis are difficult conditions with limited treatment options. We report a case of CUP leptomeningeal metastasis that was refractory to empirical chemotherapy but achieved a favorable response to intrathecal trastuzumab after the identification of human epidermal growth factor receptor-2 (HER2) amplification. A 59-year-old woman was diagnosed with CUP with metastasis of a poorly differentiated carcinoma to the left axillary, anterior mediastinal, peritoneal, and bilateral supraclavicular lymph nodes...

BACKGROUND: In aesthetic practice, delayed-onset (late) inflammatory reactions (DIRs) to dermal fillers are encountered. The treatment of DIRs can be challenging, with a response to established therapies, including oral antibiotics, intralesional and oral steroids, and hyaluronidase injection, occasionally reported as unsatisfactory. OBJECTIVES: Evaluate the efficacy of low-dose oral methotrexate (MTX) therapy in treating recalcitrant DIRs. METHODS: We retrospectively reviewed cases of recalcitrant DIRs treated with oral MTX...

BACKGROUND: Treatment for osteosarcoma, a paediatric bone cancer with no therapeutic advances in over three decades, is limited by a lack of targeted therapies. Osteosarcoma frequently metastasises to the lungs, and only 20% of patients survive 5 years after the diagnosis of metastatic disease. We found that WNT5B is the most abundant WNT expressed in osteosarcoma tumours and its expression correlates with metastasis, histologic subtype and reduced survival. METHODS: Using tumor-spheroids to model cancer stem-like cells, we performed qPCR, immunoblotting, and immunofluorescence to monitor changes in gene and protein expression...

BACKGROUND/AIM: The long-term use of proton pump inhibitors (PPIs) has been reported to be strongly associated with the development of fundic gland polyps (FGPs). Conversely, a few cases of gastric hyperplastic polyps (GHPs) associated with PPI use have been reported. We experienced a case of PPI-associated multiple GHPs with uncontrollable bleeding. CASE REPORT: A 64 year old man with a history of rheumatoid arthritis presented to the hospital with complaints of vertigo and black stools...

OBJECTIVE: To determine whether neoadjuvant gemcitabine and cisplatin (GC) versus dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin (ddMVAC) before radical cystectomy improves overall survival (OS), progression-free survival (PFS), and pathologic complete response (pCR) for patients with muscle-invasive bladder cancer (MIBC) with secondary analyses of pathological downstaging and toxicity. MATERIALS AND METHODS: This systematic review and meta-analysis identified studies of patients with MIBC treated with neoadjuvant GC compared to ddMVAC from PubMed, Web of Science, and EMBASE...

BACKGROUND: Rheumatoid arthritis (RA) is an autoimmune disease.However, there are few cases of Charcot Neuro-osteoarthropathy (CN) caused by rheumatoid diseases in clinical reports. It is not easy to pay attention to the diagnosis of CN in the complications of rheumatoid disease, which greatly increases the probability of misdiagnosis and missed diagnosis. This case reported a rare complication of rheumatoid arthritis, Charcot arthritis, and the molecular mechanism and diagnosis and treatment of CN caused by RA were systematically discussed...

Use of posttransplant cyclophosphamide (PTCy) for the prophylaxis of graft-versus-host disease (GVHD) has revolutionized the field of HLA-haploidentical stem cell transplantation, which was previously considered high-risk and only feasible in specialized centers. The rapid adoption of PTCy is attributed not only to its superior efficacy in suppressing GVHD but also to its affordability and the lack of need for specialized techniques or equipment to administer it. Recently, PTCy has gained attention for its potential effectiveness in GVHD prophylaxis beyond HLA-haploidentical stem cell transplantation...

A 69-year-old woman was referred to our hospital due to hyperleukocytosis. We diagnosed acute myeloid leukemia and started induction therapy with the CAG regimen (aclarubicin, cytarabine and filgrastim). However, the patient was refractory to the initial treatment and developed quadriplegia, and a cerebrospinal fluid (CSF) test showed elevated blasts. We then performed intrathecal chemotherapy, and the number of blasts in CSF gradually decreased. But only two cycles of intrathecal therapy were possible due to severe methotrexate-induced mucositis...

Pneumocystis jirovecii is a fungal pathogen that causes pneumocystis pneumonia, a disease that mainly affects immunocompromised individuals. This fungus has historically been hard to study because of our inability to grow it in vitro. One of the main drug targets in P. jirovecii is its dihydrofolate reductase (PjDHFR). Here, by using functional complementation of the baker's yeast ortholog, we show that PjDHFR can be inhibited by the antifolate methotrexate in a dose-dependent manner. Using deep mutational scanning of PjDHFR, we identify mutations conferring resistance to methotrexate...

OBJECTIVES: Giant cell arteritis (GCA) is one of the most common forms of vasculitis. There is an abundance of studies which are conducted in a randomised controlled trial setting but limited with respect to cohort size and follow-up time. GeVas is the first large-scale registry for vasculitides in German-speaking countries that enables to evaluate this rare disease. Herein we focus on the subgroup of GCA patients including follow-up data up to one year. METHODS: GeVas is a prospective, web-based, multicentre registry for the documentation of organ manifestations, outcomes, and therapy regimens in vasculitides...

This study investigated the impact of in vivo available colon-mango (poly)phenols on stress-induced impairment of intestinal barrier function. Caco-2/HT29-MTX cells were incubated with six extracts of ileal fluid collected pre- and 4-8 h post-mango consumption before being subjected to inflammatory stress. (Poly)phenols in ileal fluids were analysed by UHPLC-HR-MS. Epithelial barrier function was monitored by measurement of trans-epithelial electrical resistance (TEER) and the production of selected inflammatory markers (interleukin-8 (IL-8) and nitric oxide (NO)) and the major mucin of the mucosal layer (MUC2)...
