Jak inhibitors are potent anti-inflammatory drugs that have the potential to dampen the hyperactive inflammatory response associated with severe COVID-19. We reviewed the clinical outcomes of 218 patients with COVID-19 hospitalized for severe pneumonia and treated with ruxolitinib through a compassionate use program. Data on the duration of treatment, outcomes at 4, 7, 14, and 28 days, oxygen support requirements, clinical status, and laboratory parameters were retrospectively collected. Overall, according to the physician evaluation, 66.5% of patients showed improvement at follow-up, of these, 83.5% showed improvement by day 7. Oxygen support status also showed improvement, and by day 7, 21.6% of patients were on ambient air, compared with 1.4% at baseline, which increased to 48.2% by day 28. Significant decreases in C-reactive protein and increases in the lymphocyte total count were already observed by day 4, which seemed to correlate with a positive outcome. At the end of the observation period, 87.2% of patients were alive. No unexpected safety findings were observed, and grade 3/4 adverse events were reported in 6.9% of patients.

Background: The Coronavirus disease (COVID-19) pandemic is causing millions of infections and hundreds of thousands of deaths worldwide. Cumulative clinical and laboratory evidence suggest that a subset of patients with severe COVID-19 may develop a cytokine storm syndrome during the course of the disease, with severe respiratory impairment requiring ventilatory support. One field of research nowadays is to identify and treat viral-induced hyperinflammation with drugs used in other clinical conditions characterized by an hyperinflammation status. These drugs might help to reduce COVID19 mortality.Methods: Ruxolitinib, a JAK1 and JAK2 inhibitor, has been successfully used to treat severe immune-mediated diseases, such as graft vs. host disease and Hemophagocytic lymphohistiocytosis. We used ruxolitinib in 18 patients with clinically progressive COVID-19 related acute respiratory distress syndrome, with a primary endpoint to rapidly reduce the degree of respiratory impairment and as a secondary endpoint to rapidly restore the PaO2/FiO2 ratio, as an evaluation of clinical status, and monitoring of drug related Adverse Events. Parameters of inflammation responses and organ functions were assessed and monitored. The treatment plan was ruxolitinib 20 mg bid for the first 48 h and subsequent two-step de-escalation at 10 mg bid and 5 mg bid for a maximum of 14 days of treatment.Results: Our data collection shows a rapid clinical response with no evolution from non-invasive ventilation to mechanical ventilation in 16/18 patients and no response in two patients (overall response rate—ORR 89%). Already after 48 h of ruxolitinib treatment 16/18 patients showed evident clinical improvement, and after 7 days of treatment 11/18 patients showed fully recovered respiratory function (pO2 > 98% in spontaneous breathing), 4/18 patients had minimal oxygen requirement (2–4 L/m), 1/18 patient showed stable disease, and 2/18 patient showed progressive disease. After 14 days, 16/18 patients showed complete recovery of respiratory function (ORR 89%). Compliance to ruxolitinib planned treatment was 100% and no serious adverse event was recorded. In our case series of 18 critically ill patients with COVID-19 and ARDS, administration of ruxolitinib resulted in a clinical improvement that concurred to modify the standard course of disease. Ruxolitinib can be a therapeutic option for patients with respiratory insufficiency in COVID-19 related ARDS.

BACKGROUND: In the last years genomic and somatic alterations have shown to play a pivotal role in the pathogenesis of chronic lymphocytic leukemia (CLL) and new prognostic factors have been identified accordingly.AIM: To describe a real-life diagnostic and therapeutic approach to CLL that takes into account the role of genomic and somatic prognostic factors in the risk stratification of developing progressive disease, and treatment decision.METHODS: This new proposal has been developed and validated by ten key opinion leaders from Tuscany Region during two Expert Meetings. The approach suggested comes from their experience in daily clinical practice and is supported by guidelines recommendations, clinical trials results, and drugs prescribing conditions in Italy.RESULTS: Beside TP53 deletion or mutated status, the Expert Panel highlighted the importance of the IGHV mutation status characterization, since the diagnosis, in order to identify patients who will have a more aggressive progression. Furthermore, just before starting treatment, to obtain useful prognostic information and indication in the selection of the therapy, they recommend cytogenetic analysis for the detection of del(11q), trisomy 12, del(13q), del(17p), conventional karyotyping of stimulated CLL cells, TP53 sequencing, and molecular genetic analysis to detect IGHV mutation status.CONCLUSIONS: The Expert Panel recognized the limitations associated with traditional staging systems in identifying patients who will have a more aggressive disease course and predicting response to treatment and suggested a real-life diagnostic and therapeutic approach to CLL to update the current patient management in light of recent advances that have improved understanding of CLL.

This case describes a 42-year-old male affected by hypereosinophilic syndrome associated with angioimmunoblastic lymphoma. Heart involvement was suspected at ECG mimicking left ventricular hypertrophy. MRI clarified the extensive endomyocardial fibrosis, confirming the role of this technique in in-vivo tissue characterization. Finally, the study investigates the association of T cell lymphoma, hypereosinophilic syndrome, and Loeffler endomyocardial disease.

Bendamustine was introduced in Italy from 2008 and it was used as salvage therapy in patients pretreated, particularly in indolent lymphomas. Before approval as first-line treatment by the National Health System, starting from 2011 and thanks to our regional regulation, was possible to use Bendamustine in first line therapy as ‘off-label’ drug. The aim of this study was to collect all consecutive patients treated in first line with Bendamustine in 7 Tuscany centers. From June 2011 to December 2012, 72 patients were prospectively included in the study. Diagnosis was: Lymphocytic lymphoma in 25 patients (34%), Follicular lymphoma in 18 (25%), Diffuse large B cell lymphoma in 11 (15%), Mantle cell lymphoma in 10 (14%), Lymphoplasmocytic lymphoma in 5 (7%) and MALT in 3 (5%). Thirty-nine patients were treated with Bendamustine 90 mg/m2 for two days, 28 with 70 mg/m2 and 5 with 120 mg/m2. The analyzed population must be considered negatively selected as such was not proposed the standard therapy. Moreover the data coming from literature and the experience in pre-treated patients increased the interest of clinicians for this drug. In 14 patients Bendamustine was used alone, in 56 in combination with Rituximab or other drug. The overall median age was 69 years (range 45-89), in DLBCL was 81 years and 78 years in MCL. Considering the advanced age of this population we applied the geriatric score assessment and 25% of patients were unfit or frail. The median number of cycles performed was 4 (range 2 - 6). All patients but 2 were evaluable for response, 35 obtained a complete remission, 27 a partial remission considering the intention to treat the overall response rate was 86%, stable disease in 2 patients, progressive disease in 6 patients and not evaluable in 2 patients. According to histotype to note that all but two indolent lymphoma obtained a response; in aggressive lymphomas 4/11 DLBCL and 5/9 MCL reached a complete remission but 4 DLBCL and 2 MCL experienced rapid progression of the disease. Treatment was well tolerated, we observed: grade 3-4 neutropenia in 18 patients, no grade 3-4 anemia or thrombocytopenia. According to extrahematological toxicity was reported only grade 3-4 infection in 3 patients no other grade 3-4 toxicities were reported. Skin rush grade 1 was reported in in 5 patients. No toxic deaths were observed. After a median follow-up of 18 months the overall survival was 83%; 10 patients died all due to progressive disease. Progression free survival, after a median observation period of 12 months, was 60%; sixty-two patients are alive, 31 in continuous complete remission, 3 relapsed and 28 with disease under control. In conclusion in this ‘real life’ negatively selected population, the use of Bendamustine showed a very high response rate particularly in indolent lymphomas, promising results, also, are observed in aggressive lymphoma suggesting that this drug can be used with interesting result in elderly patients who can not receive the standard therapy.

Background Rituximab in combination with chemotherapy is the standard of care for patients with diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL). To improve patient convenience and to reduce healthcare resource burden, a subcutaneous (SC) formulation of rituximab has been developed and has been shown to be clinically comparable to intravenous (IV) rituximab. The aim of this study was to evaluate patient preference for rituximab IV or SC administration. Methods Prefmab (NCT01724021) is a randomized, open-label, crossover phase IIIb study. Eligible patients were aged ≥18 to ≤80 years with previously untreated CD20+ DLBCL (IPI 1-4 or 0 with bulky disease) or FL (FLIPI grade 1-3a), at least 1 bidimensionally measureable lesion ≥1.5cm at its largest dimension by computed tomography, and an ECOG performance status ≤3; all provided written informed consent. Patients received 8 cycles of rituximab according to 2 schedules: Arm A received 1 cycle of rituximab IV (375mg/m2) and 3 cycles of rituximab SC (1400mg) then 4 cycles of rituximab IV; Arm B received 4 cycles of rituximab IV (375mg/m2) then 4 cycles of rituximab SC (1400mg). Alongside rituximab, both arms received 6-8 cycles of chemotherapy (CHOP [cyclophosphamide, doxorubicin, oncovin, prednisone], CVP [cyclophosphamide, vincristine, prednisone], or bendamustine as per standard local practice). A Patient Preference Questionnaire (PPQ) was conducted post-rituximab therapy at cycles 6 and 8. The primary endpoint was overall preference for rituximab IV or SC. The strength of patient preference was also assessed (very strong, fairly strong, or not very strong). Adverse events (AEs), including administration-related reactions, were evaluated according to NCI-CTCAE version 4.0. Results At the primary data cut-off (January 19, 2015), the intent-to-treat population comprised 743 patients (Arm A: n=372; Arm B: n=371). The majority of patients had DLBCL (63%). The median age was 60 years (range 18-80) and baseline characteristics were balanced between arms. One hundred and twenty patients discontinued immunochemotherapy treatment prematurely, primarily due to AEs (n=52), but entered follow-up. A further 108 patients (Arm A: n=48; Arm B: n=60) discontinued the study and did not complete follow-up, primarily due to death (53 patients [DLBCL: n=48; FL: n=5], 19 of whom died due to progressive disease [DLBCL: n=16; FL: n=3]), patient request/withdrawal of consent (n=23), or AEs (n=9). Rates of study discontinuation and treatment discontinuation were balanced between arms. The PPQ was completed by 620 patients at cycle 6 and 591 at cycle 8. At cycle 6, rituximab SC was preferred by 80% (n=495) of patients (Arm A: 79%; Arm B: 81%) and rituximab IV by 10% (n=62; Arm A: 11%; Arm B: 9%), while 10% (n=63) had no preference (Arm A: 10%; Arm B: 10%). At cycle 8, the respective values were 81% (n=477; Arm A: 77%; Arm B: 84%), 11% (n=66; Arm A: 13%; Arm B: 10%), and 8% (n=48; Arm A: 10%; Arm B: 6%). The strength of patient preference for rituximab SC or IV is shown in Figure 1. Of patients who preferred rituximab SC, the main reasons were 'less time in the clinic' (cycle 6: 68%; cycle 8: 69%) and 'feels more comfortable during administration' (cycle 6: 37%; cycle 8: 37%). The mean cumulative rituximab administration time (mean ± standard deviation) was 865 ± 401 min for rituximab IV compared with 37 ± 100 min for rituximab SC. AEs were generally balanced between rituximab IV and SC administration, with the exception of gastrointestinal disorders (IV: 55%; SC: 31%) in patients with FL, notably nausea (IV: 28%; SC: 11%), constipation (IV: 14%; SC: 6%), and vomiting (IV 12%; SC 2%). No new safety signals were detected. Conclusions Most previously untreated patients with CD20+ DLBCL or FL preferred SC compared with IV administration of rituximab, mainly due to reduction in the duration and discomfort of administration.

Between July 1990 and March 1992, 23 elderly patients with intermediate or high-grade non-Hodgkin's lymphomas (NHL) received a combination chemotherapy (P-VABEC: Etoposide, Adriamycin and Cyclophosphamide on days 1, 15, 29, 43, Vincristine and Bleomycin on days 8, 22, 36, 50 and Prednisolone on weeks 1-9). The regimen was administered on an outpatient basis. The median age of the patients was 67 years (range 60-78); 15 were previously untreated, 8 were on second line therapy; 6 patients (44%) had stage IV disease, 19 (83%) B symptoms, 15 (65%) had bulky disease, and (26%) bone marrow involvement. The complete remission (CR) rate was 57%, and the partial remission (PR) rate 43%, with an overall response rate of (100%). No difference in response rate was observed between previously untreated patients and patients treated with P-VABEC as second-line therapy while hematological and clinical toxicity were very mild.

Aggressive treatments in elderly patients with NHL are often responsible for acute complications and increased mortality. The present study confirms that P-VABEC is able to induce a high CR rate (71%), with an overall response rate of 92%. The 4-year actuarial OS was 45%, and the FFS was 38%. Despite these good results 57% of CRs relapsed in a relatively short time (median 9.5 months; range 2-47). Because of this we decided to evaluate the role of a consolidation schedule (CIP), including idarubicin and cisplatin. The toxicity of P-VABEC/CIP regimen was comparable to that of P-VABEC alone. After a median follow-up of 20 months (range 8-49), 93% of CR patients treated with P-VABEC-CIP were still in complete remission. The 4-year actuarial overall survival was 92%, and the failure-free survival in CR patients was 72%. The difference in OS and FFS between the two groups was statistically significant. These results suggest that a short course of additional therapy is feasible in elderly patients treated with P-VABEC and may increase the OS and FFS, without adding toxicity.

Hepatitis C virus (HCV), which is both a hepatotropic and a lymphotropic virus, has been proposed as a possible causative agent of mixed cryoglobulinaemia. This 'benign' lymphoproliferative disorder can switch over to a malignant B-cell non-Hodgkin's lymphoma (NHL). Therefore HCV infection has been investigated in a series of 50 unselected Italian patients with B-cell NHL. Antibodies against HCV were found in 30% of NHL and HCV viraemia in 32% of cases. HCV-related markers were detected in 34% (17/50) of our NHL patients; this prevalence is particularly significant when compared with HCV seropositivity in Hodgkin's lymphoma (3%) and healthy controls (1.3%).

An intensive third generation regimen (P-VABEC) including adriamycin, etoposide, cyclophosphamide, vincristine, bleomycin and prednisolone was administered to 43 unselected elderly patients with intermediate or high-grade non-Hodgkin's lymphomas (NHL). The median age was 67, 40 per cent were Ann Arbor stage IV, 73 per cent had 'B' symptoms, 55 per cent had bulky disease, 48 per cent had serum lactate dehydrogenase greater than 450 U/l, 85 per cent had serum thymidine-kinase greater than 4 U/l. Thirty patients were previously untreated. The complete remission (CR) rate was 74 per cent, and the partial remission (PR) rate 23 per cent, with an overall response rate of 97 per cent. The regimen was carried out on an outpatient basis in all patients. No death occurred during therapy. The Kaplan-Meier actuarial survival of all patients at 3-years is 47 per cent, and 50 per cent (16/32) of all patients who attained CR remain alive and in remission at a median of 21+ months (range 6+ to 42+). These results confirm that high remission and failure-free survival rates can be achieved also in elderly unselected patients with aggressive NHL treated with curative intent.
