Background:Optimal adherence to imatinib therapy is of paramount importance to maximise treatment effectiveness in patients with chronic myeloid leukaemia (CML). The main objective of this study was to investigate patient-reported personal factors associated with adherence behaviour.Methods:Analysis was conducted on 413 CML patients receiving long-term therapy with imatinib. Adherence behaviour was measured with the Morisky Medication Adherence Scale and personal factors investigated included: quality of life, perceived social support, fatigue, symptom burden, psychological wellbeing and desire for additional information. Key socio-demographic and treatment-related factors were also taken into account. Univariate and multivariate logistic regression analyses were used to investigate factors associated with optimal adherence to therapy.Results:In all, 53% of patients reported an optimal adherence behaviour. The final multivariate model retained the following variables as independent predictors of optimal adherence to therapy: desire for more information (ref. no), odds ratio (OR)=0.43 (95% confidence interval (CI), 0.29–0.66; P<0.001), social support (higher score representing greater support), OR=1.29 (95% CI, 1.11–1.49; P<0.001) and concomitant drug burden (ref. no), OR=1.82 (95% CI, 1.18–2.80; P=0.006).Conclusion:This study suggests that a higher level of social support, satisfaction with information received and concomitant drug burden are the main factors associated with greater adherence to long-term imatinib therapy.

Key Points ACTN1 mutations were identified in 10 of 239 families with inherited thrombocytopenia of unknown origin. ACTN1-related thrombocytopenia is characterized by mild thrombocytopenia with platelet macrocytosis and low risk for bleeding.

Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by a hypercoagulable state related to persistently elevated levels of antiphospholipid antibodies (aPL). Current treatment for APS is only partially effective and new therapies are strongly needed. We report on a case of a 50 years old man with APS who suffered from recurrent thromboembolic episodes despite conventional anticoagulant treatment. Eight years after the first thrombotic manifestation he was diagnosed with a large B cell non-Hodgkin lymphoma. Treatment with CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) plus rituximab was started with partial clinical remission of lymphoma and normalization of aPL levels with a three years follow-up period free of thrombotic episodes.A review of the literature revealed that only 12 case reports on the use of rituximab in patients with primary, secondary and catastrophic APS have been published. Current knowledge clearly suggests the need for clinical trials to evaluate the effect of rituximab in the treatment of resistant APS.
