OBJECTIVE: Neuromyelitis optica (NMO) is a very severe autoimmune disorder of the central nervous system. It affects young subjects and has a poor prognosis both on a functional and vital level. Therefore, it is imperative to reduce the frequency of relapses. The purpose of this study was to evaluate the clinical and neuroradiological effectiveness of rituximab (RTX) on active forms of NMO. METHODS: We conducted a 2-year open prospective multicenter study that included 32 patients treated with RTX at a dose of 375 mg/m2 /week for 1 month...

OBJECTIVES: Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system. B cells play an important pathogenic role in MS. Rituximab (RTX), a B-cell depleting drug, has been used to treat MS and neuromyelitis optica (NMO). Patient characteristics, safety, and efficacy measures are reviewed to ascertain the therapeutic benefit and safety of RTX in a real-world setting with long-term follow-up. METHODS: This is a retrospective chart review of patients who received RTX at The Ohio State University's MS clinic from January 2005 to October 2016...

There is increasing interest in rituximab (RTX) as an alternative to cyclophosphamide for the treatment of interstitial lung diseases (ILDs) associated with systemic sclerosis (SSc). However, no report has addressed its efficacy in Saudi patients with SSc-ILD. To assess the efficacy of RTX treatment in Saudi patients with SSc-ILD, hospital records were reviewed between 2013 and 2016. Four female patients received at least 4 cycles of RTX (I cycle, consisting of two infusions of 1000 mg 2 weeks apart). Pulmonary function tests (PFTs) and chest high-resolution computed tomography (HRCT) were performed before and after treatment to assess the response...

The steadily increasing knowledge regarding pathogenetic mechanisms in autoimmune rheumatic diseases has paved the way to different therapeutic approaches. In particular, the market entry of biologics has dramatically modified the natural history of rheumatic chronic inflammatory diseases with a meaningful impact on patients' quality of life. Among the wide spectrum of available biological treatments, rituximab (RTX), first used in the treatment of non-Hodgkin's lymphoma, was later approved for rheumatoid arthritis and anti-neutrophil cytoplasmic antibodies-associated vasculitis...

Neuromyelitis optinca (NMO) represents a serious demyelinating disease of the central nervous system selectively attacking the spinal cord and optic nerve. Early differential diagnosis from multiple sclerosis is of vital importance, as NMO mandates immunosuppressive and not immunomodulatory treatment. Rituximab has been recently introduced as a treatment option for NMO. However, optimal surrogate measures and treatment intervals are still unclear. Five patients (females, mean age 54±10.21years) with NMO and NMO spectrum disorders (NMOSD) were evaluated with respect to disability and relapse rate...

Systemic sclerosis (SSc) is a chronic autoimmune disease with a high morbidity and mortality. Although cyclophosphamide is effective for severe and refractory cases, there is demand for new treatments. The biological treatment with B-cell depletion with rituximab (RTX) has demonstrated efficacy for this demand in open-label studies. OBJECTIVE: This study was conducted with the aim to retrospectively evaluate all patients who used RTX for the treatment of SSc in our center. PATIENTS AND METHODS: We retrospectively evaluated medical records of all patients with SSc who used RTX to treat this disease from January 2009 to January 2015...

Rituximab (RTX) is a monoclonal chimeric antibody directed against the CD20 antigen of B lymphocytes. Late onset neutropenia (LON) is a recognised complication of rituximab usually occurring 4 weeks after the last dose and is reported in both haematological and rheumatological conditions. However, it has never been described in a patient with myositis and systemic sclerosis overlap disease. We describe a case of LON in a 54-year-old man who was diagnosed with myositis and then systemic sclerosis overlap disease...

BACKGROUND: Rituximab (RTX) may favorably affect skin and lung fibrosis in patients with systemic sclerosis (SSc); however, the underlying molecular mechanisms remain unknown. We aimed to explore the hypothesis that RTX may mediate its antifibrotic effects by regulating the expression of Dickkopf-1 (Dkk-1), an inhibitor of the Wnt pathway. METHODS: Fourteen patients with SSc and five healthy subjects were recruited. Dkk-1 expression was immunohistochemically assessed in skin biopsies obtained from 11 patients with SSc (8 treated with RTX and 3 with standard treatment), whereas DKK1 gene expression was assessed in 3 patients prior to and following RTX administration...

Interstitial lung disease (ILD) is common in systemic sclerosis (SSc) patients and despite recent advances in the treatment is, at present, the major cause of death. Today, an early diagnosis of ILD is possible, and is mandatory to improve the prognosis of the disease. Pulmonary function tests and high-resolution computed tomography remain the mainstay for the diagnosis of SSc-ILD, but there is a growing interest in lung ultrasound. Recently, the correlation between severity of fibrosis and some peripheral blood biomarkers has been described...

BACKGROUND: The treatment of systemic sclerosis (SSc) represents a great clinical challenge because of the complex disease pathogenesis including vascular, fibrotic, and immune T- and B-lymphocyte-mediated alterations. Therefore, SSc should be treated by combined or sequential therapies according to prevalent clinico-pathogenetic phenotypes. Some preliminary data suggest that rituximab (RTX) may downregulate the B-cell over expression and correlated immunological abnormalities. METHODS: Here, we describe a series of 10 SSc patients (4M and 6F, mean age 46±13...

Previous studies have demonstrated that B cells play critical roles in autoimmune disorders including systemic sclerosis (SSc) and systemic lupus erythematosus (SLE). However, the effectiveness of rituximab (RTX), a chimeric anti-CD20 antibody, for SSc-associated interstitial lung disease (ILD) or SLE disease activity remains controversial. We herein report an SSc patient with severely progressed ILD and concomitant SLE treated by two cycles of RTX at baseline and half a year later. This treatment improved ILD and SLE activities, along with reduction of dermal sclerosis and serum anti-topoisomerase I antibody levels...

Rituximab (RTX) is a chimeric anti-CD20 antibody, approved for rheumatoid arthritis (RA) patients who failed anti-Tumor Necrosis Factor therapy. It has been used occasionally for life-threatening autoimmune diseases (AID). We report our center experience in the use of RTX in life-threatening complications or refractory AID. Clinical charts of patients treated with RTX at our center were reviewed, cases treated for life-threatening complications or refractory AID were analyzed. Acute damage to vital organs such as lung, heart, kidney, nervous system with severe functional impairment were defined as life-threatening complications; treatment failure with high-dose corticosteroids, cyclophosphamide, IVIG, plasmapheresis was defined as refractory autoimmune disease...

INTRODUCTION: Recently, several studies assessing the clinical efficacy of rituximab (RTX) in systemic sclerosis (SSc) have reported encouraging results. We aimed at exploring whether RTX exerts its beneficial effects on fibrosis through attenuation of platelet-derived growth factor receptor (PDGFR) pathway activation. METHODS: We immunohistochemically assessed skin biopsies obtained from eight patients with SSc prior to and 6 months following RTX treatment, three control SSc patients (at the same time points) and three healthy subjects...

Systemic sclerosis (SSc) is a systemic rheumatic disease with poor prognosis since therapeutic options are limited. Recent evidence from animal models suggests that B-cells may be actively involved in the fibrotic process. B-cells from tight skin mice, an animal model of scleroderma, display a "hyperresponsive" phenotype; treatment with rituximab (RTX) significantly attenuates skin fibrosis in this animal model. In humans, B-cell infiltration is a prominent finding in most lung biopsies obtained from patients with SSc-associated interstitial lung disease...
