Background: During the past decades, beta thalassemia major (TM) and beta thalassemia intermedia (TI) have transformed from a universally fatal disease at a young age into a chronic disease. This advancement is attributed to improved chelation therapy as well as enhanced management strategies, with focused attention on disease and treatment-related complications.

Objectives: To describe characteristics of adults with thalassemia as well as treatment modalities, disease and treatment-related complications, and socioeconomic information of the patients.

Methods: We preformed a retrospective analysis of 14 adult patients > 35 years of age with TM and TI who were treated at our institute, a single center specializing in the care of adult thalassemia patients living in Israel, between the years 2006 and 2016.

Results: The median age of patients was 37 years and most patients were transfusion-dependent. The median number of chelation therapeutic lines was three, and 85.7% of patients were treated at one point by combination chelation therapy. Most patients suffered from at least some form of endocrine dysfunction (n=12), and four patients developed overt heart failure. Of the patients, 85% had completed at least a high school education, 78% were employed, and 64.2% were married.

Conclusions: Prolonged survival of thalassemia patients in recent years has been accompanied by a new set of challenges for both the patients and the treating staff. Further research is warranted to improve both medical management and the socioeconomic well-being of this unique group of adult thalassemia patients.

Background: Pulmonary infiltrates (PIs) detected in patients with non-Hodgkin lymphoma (NHL) may present a diagnostic challenge due to their wide differential diagnosis, including infection, pulmonary lymphoma and immunochemotherapy-associated pulmonary toxicity.

Objectives: To characterize therapy-associated PIs by positron emission tomography/computed tomography (PET/CT) imaging.

Methods: We conducted a historical analysis of fluorodeoxyglucose-PET/CT (¹⁸F-FDG-PET/CT) PIs in NHL patients treated with combined immunochemotherapy including rituximab. Incidence of PIs, radiological features, patients’ characteristics, underlying NHL type, rituximab/chemotherapy dosing schedules, and symptoms were recorded. Therapy-associated PIs were defined as new or worsening PIs appearing after treatment onset, without evidence of active pulmonary lymphoma or infection.

Results: Among 80 patients who met the pre-specified criteria, therapy-associated PIs were identified in 17 (21%), 6 of whom had accompanying symptoms. Increased FDG uptake was observed in nine, and PI resolution in six. The incidence of PIs was higher in females and in patients with aggressive lymphoma, at advanced stages, and in those who had received treatment consisting of a combination of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone every 14 days (R-CHOP-14).

Conclusions: This characterization of therapy-associated PIs may support the clinician managing NHL patients. Further prospective studies are needed to establish the role of each therapeutic component and the natural history of this phenomenon.
