Regular transfusion and iron chelation are the current treatment of severe forms of thalassemia. As a consequence of this demanding supportive treatment, there are several unmet therapeutic needs. Due to a deeper understanding in the pathophysiology of thalassemia, new therapeutic strategies have been developed that are now in pre-clinical and clinical trials. Areas covered: Activin receptor ligand traps (luspatercept and sotatercept), drugs targeting ineffective erythropoiesis, showed encouraging results in Phase I and II clinical trials. A phase III clinical trial is currently ongoing. Ruxolitinib, a Jak2 inhibitor, has been tested to limit stress erythropoiesis in a phase II clinical trial. In addition, improvement in iron chelation has been developed. Moreover, several trials of gene therapy are currently active in different countries with different lentiviral vectors. Expert opinion: The most promising molecules are the activin receptor ligand traps. Together with gene therapy these could be an alternative to bone marrow transplant, aiming towards a curative strategy. The main limit to gene therapy seems to be the conditioning regimen, thus an in vivo gene therapy would be more suitable. At pre-clinical level gene editing is showing extremely encouraging results.

Currently, chronic obstructive pulmonary disease (COPD) represents the fourth cause of death worldwide with significant economic burden. Comorbidities increase in number and severity with age and are identified as important determinants that influence the prognosis. In this observational study, we retrospectively analyzed data collected from the RePoSI register. We aimed to investigate comorbidities and outcomes in a cohort of hospitalized elderly patients with the clinical diagnosis of COPD. Socio-demographic, clinical characteristics and laboratory findings were considered. The association between variables and in-hospital, 3-month and 1-year follow-up were analyzed. Among 4696 in-patients, 932 (19.8%) had a diagnosis of COPD. Patients with COPD had more hospitalization, a significant overt cognitive impairment, a clinically significant disability and more depression in comparison with non-COPD subjects. COPD patients took more drugs, both at admission, in-hospital stay, discharge and 3-month and 1-year follow-up. 14 comorbidities were more frequent in COPD patients. Cerebrovascular disease was an independent predictor of in-hospital mortality. At 3-month follow-up, male sex and hepatic cirrhosis were independently associated with mortality. ICS-LABA therapy was predictor of mortality at in-hospital, 3-month and 1-year follow-up. This analysis showed the severity of impact of COPD and its comorbidities in the real life of internal medicine and geriatric wards.
