Short-term effectiveness of golimumab for ulcerative colitis: Observational multicenter study
2016
AIM To evaluate the real-world effectiveness of golimumab in ulcerative colitis (UC) and to identify predictors of response. METHODS We conducted an observational, prospective and multi-center study in UC patients treated with golimumab, from September 2014 to September 2015. Clinical activity was assessed at wk 0 and 14 with the physician' s global clinical assessment (PGA) and the partial Mayo score. Colonoscopies and blood tests were performed, following daily-practice clinical criteria, and the results were recorded in an SPSS database. RESULTS Thirty-three consecutive patients with moderately to severely active UC were included. Among them, 54.5% were female and 42 years was the averag…
Addition of rituximab to standard therapy improves response rate and progression-free survival in relapsed or refractory thrombotic thrombocytopenic …
2007
SummaryTreatment of relapsed or refractory autoimmune mediated haemolytic syndromes, such as autoimmune haemolytic anaemia (AIHA) and thrombotic thrombocytopenic purpura (TTP), represents a therapeutic challenge. Here we report on our experience with the monoclonal anti-CD20 antibody rituximab (R) compared to standard treatment in these diseases. Patients with non-familialTTP orAIHA and no underlying malignancy were included in our analysis. Safety and efficacy of R-treatment were compared to results obtained in standard treatment approaches. Altogether, 27 patients were analyzed, comprising 15 patients withTTP and 12 patients with AIHA. The patients’ average age at the time of diagnosis wa…
Immediate versus delayed facilitated percutaneous coronary intervention. A pilot study
2005
The study was aimed to investigate the outcomes in patients initially successfully treated pharmacologically and immediate PCI <2 hours, and in patients initially successfully treated with pharmacological therapy and delayed PCI (12-72 hours). All patients had to have successful reperfusion, to receive the combination of a standard abciximab infusion plus half dose rtPA. Similar results were observed in both groups. Delayed PCI group showed a favorable trend in restenosis and bleedings (ns) and a significant reduced angiographic evidence of thrombus formation in IRA. Our very preliminary data suggest the safety and possible use of delayed facilitated PCI in patients with STEMI. The studied …
Treatment of refractory uveitis with adalimumab: a prospective multicenter study of 131 patients.
2011
To evaluate adalimumab therapy in refractory uveitis.Prospective case series.A total of 131 patients with refractory uveitis and intolerance or failure to respond to prednisone and at least 1 other systemic immunosuppressive drug participated.Patients received a 40 mg adalimumab subcutaneous injection every other week for 6 months. The associated immunosuppressants were tapered after administering 3 adalimumab injections (week 6).Degree of anterior and posterior chamber inflammation (Standardization of Uveitis Nomenclature Working Group criteria), immunosuppression load (as defined by Nussenblatt et al), visual acuity (logarithm of the minimal angle of resolution [logMAR]), and macular thic…
A multicenter clinical trial on the use of alpha1-antichymotrypsin-prostate-specific antigen in prostate cancer diagnosis
2001
BACKGROUND The aim was to evaluate the clinical performance of alpha1-antichymotrypsin prostate-specific antigen (PSA-ACT) for early diagnosis of prostate cancer (PCa) in a multicenter trial. METHODS Three hundred sixty-seven white men with PCa and 290 with benign prostatic hyperplasia (BPH) with tPSA concentrations between 2 and 20 μg/L were analyzed. The Elecsys system 2010 (Roche Diagnostics, Germany) was used for determination of total PSA (tPSA) and free PSA (fPSA). The PSA-ACT test was a prototype assay used on the ES system (Roche Diagnostics). RESULTS The median concentrations of tPSA (PCa: 8.43 μg/L vs. BPH: 6.60 μg/L) and PSA-ACT (8.30 μg/L vs. 6.46 μg/L) were significantly differ…
Islet autoantibodies in Latvian subjects with non-insulin-dependent diabetes mellitus: slow-onset type 1 diabetes or polyendocrine autoimmunity?
2006
In Latvia diabetes mellitus is diagnosed using the WHO's clinical criteria; assays for the detection of autoantibodies are not available, and hence slowly progressive autoimmune diabetes is likely to be missed. Autoantibodies against glutamic acid decarboxylase (GAD65) and protein tyrosine phosphatase (IA-2) among patients with clinically diagnosed NIDDM identify group of patients with slow-onset type 1 diabetes or LADA. The aim of this study was to estimate the risk of polyendocrine autoimmunity among clinically diagnosed NIDDM patients from Latvia. One hundred NIDDM patients and 100 healthy controls were tested for GAD65 and IA-2 autoantibodies as well as 21-hydroxylase (21-OH) and tissue…
Efficacy and Safety of Subcutaneous Belimumab in Anti–Double-Stranded DNA–Positive, Hypocomplementemic Patients With Systemic Lupus Erythematosus
2018
Objective: To investigate the efficacy and safety of belimumab, a human immunoglobulin monoclonal antibody against B lymphocyte stimulator, in a subset of patients with systemic lupus erythematosus (SLE) who were hypocomplementemic (C3 <90 mg/dl and/or C4 <10 mg/dl) and anti–double-stranded DNA (anti-dsDNA) positive (≥30 IU/ml) at baseline. Methods: In this phase III, double-blind, placebo-controlled study (BEL112341; ClinicalTrials.gov identifier: NCT01484496), patients with moderate to severe SLE (Safety of Estrogens in Lupus Erythematosus National Assessment version of the Systemic Lupus Erythematosus Disease Activity Index [SELENA–SLEDAI] score ≥8) were randomized (2:1) to receive weekl…
Treatment of psoriasis with the chimeric monoclonal antibody against tumor necrosis factor alpha, infliximab.
2002
Abstract Background: Psoriatic skin lesions in patients with Crohn's disease or psoriatic arthritis have shown improvement during infliximab treatment. Objective: The purpose of our study was to systematically assess the effects of infliximab in patients with psoriatic skin lesions. Methods: Eight patients with severe psoriasis were enrolled in an open-label clinical trial. Patients received infliximab, 5 mg/kg, intravenously at weeks 0, 2, and 6. The Psoriasis Area and Severity Index (PASI) was used to monitor disease activity at weeks 0, 2, 4, 6, 8, 10, and 14. Week 10 was the end point of the treatment phase; week 14 was the follow-up end point. Pruritus was assessed on a scale of 0 to 3…
Cyclosporine or infliximab as rescue therapy in severe refractory ulcerative colitis: Early and long-term data from a retrospective observational stu…
2011
Introduction: About 30-40% of patients with acute severe ulcerative colitis (UC) fail to respond to intensive intravenous (iv) corticosteroid treatment. Iv cyclosporine and infliximab are an effective rescue therapy in steroid-refractory UC patients but up to now it is still unclear which is the best therapeutic choice. Methods: We reviewed our series of severe steroid-refractory colitis admitted consecutively since 1994 comparing two historical cohort treated with iv cyclosporine (2 mg/kg) or iv infliximab (5 mg/kg). The main outcome was the colectomy rate at 3 months, 12 months and at the end of the follow-up. Results: A total of 65 patients were included: 35 in the cyclosporine group and…
The presence of infection-related antiphospholipid antibodies in infective endocarditis determines a major risk factor for embolic events.
1999
Abstract OBJECTIVES The impact of infection-associated antiphospholipid antibodies (APA) on endothelial cell activation, blood coagulation and fibrinolysis was evaluated in patients with infective endocarditis with and without major embolic events. BACKGROUND An embolic event is a common and severe complication of infective endocarditis. Despite the fact that APAs are known to be associated with infectious diseases, their pathogenic role in infective endocarditis has not been clearly defined. METHODS The relationship among the occurrence of major embolic events, echocardiographic vegetation size, endothelial cell activation, thrombin generation, fibrinolysis and APA was examined in 91 patie…
