Splenectomy for primary immune thrombocytopenia revisited in the era of thrombopoietin receptor agonists: New insights for an old treatment
2022
Although splenectomy is still considered the most effective curative treatment for immune thrombocytopenia (ITP), its use has significantly declined in the last decade, especially since the approval of thrombopoietin receptor agonists (TPO-RAs). The main objective of the study was to determine whether splenectomy was still as effective nowadays, particularly for patients with failure to respond to TPO-RAs. Our secondary objective was to assess, among patients who relapsed after splenectomy, the pattern of response to treatments used before splenectomy. This multicentre retrospective study involved adults who underwent splenectomy for ITP in France from 2011 to 2020. Response status was defi…
Continuous intravenous infusion of dipyridamole as adjunctive therapy in the treatment of thrombotic thrombocytopenic purpura.
2003
Abstract Thrombotic thrombocytopenic purpura (TTP) is an uncommon hematologic thrombotic disorder characterized by fever, hemorrhagic and neurologic signs. The advent of plasma exchange has dramatically improved the prognosis of this disease, which was once inevitably fatal. However, mortality rates remain significant. Antiplatelet drugs have been widely used in combination with plasma exchange. In this pilot study we investigated the effects of an adjunctive therapy consisting of the continuous, intravenous infusion of dipyridamole, a modality of administration that has not been previously tested in this setting. Sixteen untreated TTP patients, diagnosed consecutively at our clinic, receiv…
Outcome of enzyme replacement therapy in patients with Gaucher disease type I. The Romanian experience
2007
This study reports the first evaluation of therapeutic response in Romanian patients with Gaucher disease type I, after therapy with Cerezyme recently became available in our country.24 patients (11-50 years) received Cerezyme 20-60 U/kg every two weeks for at least 18 months. Haemoglobin, platelet count, volume of the liver and spleen, plasma chitotriosidase and the severity score were assessed every 6 months; skeletal radiography and osteodensitometry were also monitored.Eleven patients were splenectomized before start of therapy. Eight patients had anaemia (mean haemoglobin 9.4 g/dl) and 14 patients, of whom 13 were without splenectomy, had thrombocytopenia (mean 65,692/mm3). Haemoglobin…
Predictors of mortality in HIV-infected patients starting antiretroviral therapy in a rural hospital in Tanzania
2008
Background Studies of antiretroviral therapy (ART) programs in Africa have shown high initial mortality. Factors contributing to this high mortality are poorly described. The aim of the present study was to assess mortality and to identify predictors of mortality in HIV-infected patients starting ART in a rural hospital in Tanzania. Methods This was a cohort study of 320 treatment-naïve adults who started ART between October 2003 and November 2006. Reliable CD4 cell counts were not available, thus ART initiation was based on clinical criteria in accordance with WHO and Tanzanian guidelines. Kaplan-Meier models were used to estimate mortality and Cox proportional hazards models to identify p…
Clinical features of oral lichen planus. A retrospective study of 65 cases
2010
Objectives: To describe the clinical features of patients diagnosed with oral lichen planus (OLP) and to establish the prevalence of its malignant transformation in our setting. Study design: A retrospective study was made of 65 patients clinically and histologically diagnosed with OLP in the Service of Oral Surgery (Dental Clinic of the University of Barcelona, Spain) in the period 1990-2005. A descriptive and bivariate statistical analysis was made. Results: The mean patient age was 59 years (SD ± 14.9). Most of the patients (61%) were women, and the most frequent location of the lesions was the buccal mucosa (90.8%). White forms of OLP were noted in 66% of the cases, and 46.2% of the pat…
Antimicrobial prophylaxis in patients with immune thrombocytopenia treated with rituximab: a retrospective multicenter analysis
2021
The primary aim of this study was to describe the use of primary anti-infective prophylaxis (AP) in common clinical practice in patients affected by immune thrombocytopenia (ITP) and treated with RTX. Population studied consisted of patients affected by ITP (age ≥ 18 years) who had received at least one dose of RTX from January 2008 to June 2018. Five Italian haematology centres participated in the current study. Data were retrospectively collected: demographic data (age, gender), concomitant comorbidities and previous therapies for ITP, characteristics of AP, the occurrence of infections and their management. The ITP cohort consisted of 67 patients sub-grouped into two categories according…
Relapse Rate in Survivors of Acute Autoimmune Thrombotic Thrombocytopenic Purpura Treated with or without Rituximab.
2018
Background Autoimmune thrombotic thrombocytopenic purpura (iTTP) is caused by autoantibody-mediated severe a disintegrin and metalloprotease with thrombospondin type 1 repeats, member 13 (ADAMTS13) deficiency leading to micro-angiopathic haemolytic anaemia (MAHA) and thrombocytopenia with organ damage. Patients survive with plasma exchange (PEX), fresh frozen plasma replacement and corticosteroid treatment. Anti-CD20 monoclonal antibody rituximab is increasingly used in patients resistant to conventional PEX or relapsing after an acute bout. Objective This retrospective observational study focused on the relapse rate and possible influencing factors including treatment with rituximab first…
A pioneering epidemiological study investigating the incidence of squamous cell carcinoma of tongue in a Portuguese population
2012
Objective: The purpose of this study was to investigate the incidence of squamous cell carcinoma (SCC) of the anterior two thirds of the tongue in a population living in central and southern Portugal, all treated at Portuguese Institute of Oncology of Lisbon, Francisco Gentil (IPOLFG). Study Design: This study was a retrospective review of all patients who had a histopathological diagnosis of SCC of the anterior two thirds of the tongue and had been treated in the Head and Neck Surgery Unit at the IPOLFG (Lisbon, Portugal), between 1st January 2001 and 31st December 2009. The risk factors evaluated were: gender; age; alcohol consumption; tobacco use; prosthesis use and the carcinoma site. R…
Home parenteral nutrition-associated thromboembolic and bleeding events: results of a cohort study of 236 individuals
2016
UNLABELLED Essentials Sparse or outdated studies focus on thrombotic and bleeding risk in home parenteral nutrition (HPN). 236 HPN patients followed at a single center for a total of 684 patient-years were evaluated. Rates of venous thrombosis and major bleeding, and prevalence of vena cava syndrome are provided. Anticoagulants might reduce thrombosis risk, but population-specific safety concerns remain. SUMMARY Background Home parenteral nutrition (HPN) is necessary for patients with intestinal failure. Recurrent catheter-related thrombosis (CRT) is common, leading to infectious complications, pulmonary embolism, vascular access loss and intestinal transplantation. The efficacy and safety …
Baseline characteristics and outcome in Romanian patients with Gaucher disease type 1.
2009
Abstract Background/aim To present clinical and genetic characteristics of all Romanian patients with Gaucher disease type 1, in whom specific diagnosis has been confirmed by enzymatic and molecular methods and to analyze their outcome with and without enzymatic replacement therapy (ERT). Patients, methods There are fifty patients (F/M — 1.63/1) with Gaucher disease type 1. Clinical status, haemoglobin, thrombocytes, hepatic/splenic volume, bone mineral density and severity score were assessed at baseline and every six months thereafter. Thirty-nine patients (78%) received imiglucerase (44.4 ± 13.6 U/kg/2 weeks) for 3.1 +/− 1.4 years. Results Based on general prevalence data, our group repr…
