Rituximab in the treatment of immune thrombocytopenia: What is the role of this agent in 2019?
No full textThe use of rituximab for the treatment of immune thrombocytopenia was greeted enthusiastically: it led to up to 60% response rates, making it, nearly 20 years ago, the main alternative to splenectomy, with far fewer side effects. However, long-term follow-up data showed that only 20-30% of patients maintained the remission. No significant changes have been registered using different dose schedules and timing of administration, while the combination with other drugs seemed promising. Higher response rates have been observed in young women before the chronic phase, but apart from that, other clinical factors or biomarkers predictive of response are still lacking. In this review we examine the historical and current role of rituximab in the management of immune thrombocytopenia, 20 years after its first use for the treatment of autoimmune diseases

Clinical features and outcome of multiple myeloma arising from the transformation of a monoclonal gammapathy of undetermined significance.
No full textPatients with a monoclonal gammapathy of undetermined significance (MGUS) are usually submitted to a periodical clinical follow-up, but it is not known if this surveillance can ameliorate the prognosis of a plasma cell malignancy that will be eventually detected. We compared the clinical and laboratory characteristics at onset, the response to chemotherapy and the survival, of 21 cases of newly diagnosed multiple myeloma (MM) arising from the malignant transformation of MGUS and 41 cases without a previous history of MGUS, recruited to the same first-line treatments over a 3-years period. The former group showed a significant lower frequency of advanced stages as well as other several prognostic factors of high risk including anemia, renal failure, bone lesions and increase of beta2 microglobulin and C-reactive protein levels. Despite a similar response to treatment of the two groups, MM arising from MGUS showed a significantly longer median survival than MM without prior MGUS. This was particularly true for stage I, while stages II and III behaved similarly. We conclude that the regular clinical monitoring of MGUS patients allowed the identification of earlier malignant transformation, when tumor burden is lower, as indicated by lower beta2 microglobulin levels and narrow plasmacytosis of stage I MM arising from MGUS. Moreover, a slower proliferation rate of myeloma cells, as suggested by lower C-reactive protein levels, may be considered so as to explain the longer survival of these patients

No full textManagement of immune thrombocytopenia in elderly patients
No full textDespite the improvement in understanding its pathogenesis and the introduction of novel treatment options, the management of primary immune thrombocytopenia (ITP) still remains challenging. Considering its increased incidence with aging and prolonged life-expectancy, ITP is often diagnosed in elderly patients, a subset that deserves some special precautions. Ensure the diagnosis is a crucial step, and carefully attention must be given in excluding other causes of thrombocytopenia, especially among older people that frequently suffer from many comorbidities. When it comes to treatment decision, it is worth keeping into account that the elderly have an increased risk of bleeding, thrombosis and infections, that they often require many concomitant therapies, including antiplatelet or anticoagulant agents, and that treatment-related toxicities are often increased and sometimes more dangerous that the disease itself. There are not dedicated guidelines, and only few specific studies. Steroids with or without IVIG remain the first-line treatment. Splenectomy is less effective than in youngers and burdened by an increased thrombotic and infectious risk. Rituximab is a good option in non-immunocompromised patients, but long-term remissions are few. Eltrombopag and romiplostim have a good safety and efficacy profile, and have become a prominent drug in this subset, even if they are associated with a possible increased risk of thrombosis, and long-term toxicity is unknown. Other drugs, such as dapsone and danazol, have a well-known efficacy and safety profile, and still represent a valid option among elderly patients
Immune thrombocytopenia
No full textIntroduction: Primary immune thrombocytopenia (ITP) is an autoimmune disorder characterized by a low platelet count (<100 × 109/L) with an increased risk of bleeding. Recent (2019) guidelines from the International Consensus Report (ICR) expert panel and the American Society of Hematology (ASH) provide updated recommendations for the diagnosis and management of ITP. Areas covered: The 2019 ICR and ASH guidelines are reviewed, and differences and similarities highlighted. Clinical approaches to the treatment of ITP are discussed, including the role of fostamatinib which is an approved treatment option in adult patients who are refractory to other treatments. Expert opinion: The 2019 ICR and ASH guidelines reflect recent changes in the management of ITP. Current treatment approaches for ITP are more rational and evidence-based than in the past. Patients should be treated based on their needs rather than on disease stage, and patient-specific outcomes, (e.g. quality of life) should be considered. Whilst corticosteroids are the mainstay of initial ITP treatment their use should be limited. For subsequent treatment, the use of thrombopoietin receptor agonist (TPO-RA) agents, fostamatinib and rituximab in adults is supported by robust evidence. Rituximab and recently approved fostamatinib offer viable alternatives to splenectomy
