Elotuzumab plus pomalidomide and dexamethasone in relapsed/refractory multiple myeloma: a multicenter, retrospective, real-world experience with 200 cases outside of controlled clinical trials. Haematologica 2024; 109:245-255. [PMID: 37439329 PMCID: PMC10772491 DOI: 10.3324/haematol.2023.283251] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Accepted: 07/06/2023] [Indexed: 07/14/2023] Open
Abstract
In the ELOQUENT-3 trial, the combination of elotuzumab, pomalidomide and dexamethasone (EloPd) proved to have a superior clinical benefit over pomalidomide and dexamethasone with a manageable toxicity profile, leading to its approval for the treatment of patients with relapsed/refractory multiple myeloma (RRMM) who have received at least two prior therapies, including lenalidomide and a proteasome inhibitor. We report here a real-world experience of 200 cases of RRMM treated with EloPd in 35 Italian centers outside of clinical trials. In our dataset, the median number of prior lines of therapy was two, with 51% of cases undergoing autologous stem cell transplant and 73% having been exposed to daratumumab. After a median follow-up of 9 months, 126 patients had stopped EloPd, most of them (88.9%) because of disease progression. The overall response rate was 55.4%, a finding in line with the pivotal trial results. Regarding adverse events, the toxicity profile in our cohort was similar to that in the ELOQUENT-3 trial, with no significant differences between younger (<70 years) and older patients. The median progression-free survival was 7 months, which was shorter than that observed in ELOQUENT-3, probably because of the different clinical characteristics of the two cohorts. Interestingly, International Staging System stage III disease was associated with worse progression-free survival (hazard ratio=2.55). Finally, the median overall survival of our series was shorter than that observed in the ELOQUENT-3 trial (17.5 vs. 29.8 months). In conclusion, our real-world study confirms that EloPd is a safe and possible therapeutic choice for patients with RRMM who have received at least two prior therapies, including lenalidomide and a proteasome inhibitor.

Gaucher disease prevalence in 600 patients affected by monoclonal gammopathy of undetermined significance. Eur J Haematol 2023; 111:922-929. [PMID: 37747757 DOI: 10.1111/ejh.14105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 09/08/2023] [Accepted: 09/11/2023] [Indexed: 09/26/2023]
Abstract
BACKGROUND Gaucher disease (GD) is a rare autosomal recessive inherited disorder caused by the lysosomal enzyme acid β-glucosidase deficiency. Many patients experience a critical delay in the diagnosis of up to 8-10 years due to its rarity and variability in signs and symptoms, with the consultation of several specialists. PATIENTS AND METHODS This prospective observational study analyzed the prevalence of GD in 600 patients with monoclonal gammopathy of uncertain significance (MGUS) from January 2018 until February 2022. RESULTS The mean age of participants was 66 years, with a mean monoclonal component of 0.58 g/dL. In 433 MGUS patients with available data, anemia (hemoglobin level < 10 g/dL) was present in 31 patients (7%), and thrombocytopenia (platelet count <100.000/mm3 ) in 24 (5.5%). Of 600 MGUS patients tested for acid β-glucosidase enzyme activity, 7 patients (1.2%) had activity below 2.5 nmol/h/mL. In comparison, GBA gene analysis was executed in 110 patients. It revealed 4 patients (0.7%) affected by GD (3 patients with compound heterozygous mutation and 1 with homozygous mutation), with a prevalence of 1 every 150 MGUS patients. Furthermore, 12 out of the remaining 106 evaluated patients (11%) were carriers of a single heterozygous mutation while having regular enzyme activity. CONCLUSIONS The clinical heterogeneity of GD and frequent lack of awareness among physicians often lead to diagnostic delays and severe clinical manifestations. The role of MGUS in the presence of at least one clinical sign, such as low platelet count, organomegaly, bone pain, or bleeding tendency, could aid in initiating GD screening with DBS, thus reducing the period between symptom onset and the diagnosis of this rare disease.

Abstract
The combination of elotuzumab, lenalidomide, and dexamethasone (EloRd) enhanced the clinical benefit over Rd with a manageable toxicity profile in the ELOQUENT-2 trial, leading to its approval in relapsed/refractory multiple myeloma (RRMM). The present study is a 3-year follow-up update of a previously published Italian real-life RRMM cohort of patients treated with EloRd. This revised analysis entered 319 RRMM patients accrued in 41 Italian centers. After a median follow-up of 36 months (range 6-55), 236 patients experienced disease progression or died. Median progression-free survival (PFS) and overall survival (OS) were 18.4 and 34 months, respectively. The updated multivariate analyses showed a significant reduction of PFS and OS benefit magnitude only in cases with ISS stage III. Major adverse events included grade 3/4 neutropenia (18.5%), anemia (15.4%), lymphocytopenia (12.5%), and thrombocytopenia (10.7%), while infection rates and pneumonia were 33.9% and 18.9%, respectively. No new safety signals with longer follow-up have been observed. Of 319 patients, 245 (76.7%) reached at least a partial remission. A significantly lower response rate was found in patients previously exposed to lenalidomide. In conclusion, our study confirms that EloRd is a safe and effective regimen for RRMM patients, maintaining benefits across multiple unfavorable subgroups. This article is protected by copyright.

Daratumumab as Single Agent in Relapsed/Refractory Myeloma Patients: A Retrospective Real-Life Survey. Front Oncol 2021; 11:624405. [PMID: 33763359 PMCID: PMC7982826 DOI: 10.3389/fonc.2021.624405] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Accepted: 01/04/2021] [Indexed: 12/13/2022] Open
Abstract
Background The anti-CD38 monoclonal antibody daratumumab is approved as a single agent for the treatment of patients with relapsed/refractory multiple myeloma (RRMM) who received at least three prior lines of therapy, including proteasome inhibitor and immunomodulatory agent. A retrospective multicentric study was designed to evaluate feasibility, tolerability, and efficacy of daratumumab in monotherapy in RRMM. Methods This study included 44 consecutive RRMM patients that underwent daratumumab monotherapy after a median number of four prior therapies (range 2–9). Patients were treated in seven Sicilian centers, as part of Sicilian Myeloma Network and three Calabrian centers outside of controlled clinical trials from August 2016 through July 2020. Results The regimen was well tolerated with few grade 3–4 haematological and rare non-haematological adverse events, such as pneumonia. Definitive discontinuation was due to disease progression in 25 (57%) patients. Since three patients did not complete at least one full cycle, a total of 41 patients was evaluated for response. Overall response rate was 37%, and the disease control rate (stable disease or better) was high (73%). The best achieved responses within 6 months were very good partial remission or better (27%), partial remission (10%), minimal response (14%) and stable disease (22%). After a median follow up of 7.8 months, median progression free survival (PFS) was 7.2 months and overall survival (OS) 7.8 months. Univariate analysis showed that patients with PR or better after 6 months of therapy had longer median PFS and OS (respectively 29.5 vs 3.6 months, p=0.0001 and 30.6 vs 3.9 months p=0.0001), confirmed by multivariate analysis. Furthermore, standard cytogenetic risk and biochemical relapse type had prolonged median PFS, but not OS (respectively unreached vs 2.6, p=0.03 and 23.9 vs 6.2, p=0.05) in both univariate and multivariate analysis. Additionally, univariate analysis showed that patients treated with carfilzomib-lenalidomide-dexamethasone prior to daratumumab had significantly shorter PFS compared to pomalidomide-dexamethasone (3.4 months vs 9.3 months, p=0.03), that multivariate analysis failed to confirm. Conclusions Our findings indicate that daratumumab as single agent is safe and well-tolerated regimen in real-life, associated to prolonged PFS and OS in responding patients. No new safety signals were identified.

Abstract
Abstract
Background
Ischemic time duration is one of the most important determinants of infarct size in patients with ST-segment elevation myocardial infarction (STEMI). An early reperfusion with percutaneous coronary intervention (PCI) therapy reduces the adverse events and mortality. It also influences the wall motion abnormalities and left ventricular ejection fraction (LVEF), which can be easily detected by a standard transthoracic echocardiogram (TTE).
Purpose
Aim of our study was to assess the immediate effects of an early percutaneous revascularization in STEMI patients on variations of the left ventricle (LV) global and regional function.
Methods
The study population consists of 141 consecutive patients with STEMI undergoing PCI from January to June 2018. The population was divided into two groups basing on first medical contact-to-balloon time (C2B), respectively ≤90 minutes and >90 minutes. Cardiac biomarkers were obtained uniformly. A standard TTE was performed in all patients, at moment of in-hospital admission and at the time of discharge, recording the LV wall motion abnormalities and LVEF, using the wall motion score index (WMSI) and modified Simpson’s rule, respectively. Finally, we performed a sub-analysis in the group of patients who showed an improvement of the LVEF ≥10% at discharge.
Results
In both groups at baseline, patients suffered from a moderately reduced LVEF (41 ± 8.3% in ≤90 min group vs 40.97 ± 8.91% in >90 min group, p = ns). A WMSI >1 was recorded uniformly: 1.78 ± 0.39 in patients with C2B ≤90 min and 1.81 ± 0.40 in patients with C2B >90 min, without significant differences between the two groups. At the time of discharge, a significant improvement of LVEF (from 41 ± 8% to 44 ± 9%, p = 0.013) and WMSI (from 1.78 ± 0.39 to 1.64 ± 0.38, p = 0.036) exclusively emerged in the ≤90 min group. Furthermore, we identified 37 patients who experienced, at the time of discharge, an improvement of the LVEF ≥10% compared to baseline values. In these patients the C2B time resulted significantly shorter, when compared with patients with LVEF improvement <10%: 42 min (IQR 18.5-77.5) vs. 104 (IQR 48-176), p < 0.0001. Additionally, these patients had lower significant levels of cardiac biomarkers. A significant improvement in WMSI was also observed in the ≥10% group (1,69 ± 0,41 vs 1,49 ± 0,41, p= 0.039).
Conclusion
Our study shows the immediate effects of an early revascularization. In particular, the duration of C2B time influences the recovery of ventricular function, in terms of ejection fraction and parietal kinetics. A standard TTE is a low cost and easily available examination, which may provide immediate results without impacting significantly on health costs.

Abstract
Abstract
Background
MitraClip system has developed as a valid therapeutic option in patients affected by moderate to severe and severe mitral regurgitation, low left ventricular ejection fraction (LVEF) and high surgical risk. Often, after the procedure occurs afterload mismatch, an acute and transient worsening of LVEF. Inotropic drugs can improve hemodynamic values at the prize of severe side effects. Levosimendan increases myocardial contractility without an elevation of intracellular calcium concentration, tachyarrhythmia and cardiomyocytes necrosis.
Purpose
Aim of our study was to assess the acute Levosimendan effects on LVEF of patients who underwent MitraClip procedure
Methods
Among 160 patients who underwent MitraClip procedure in our institute, 99 patients, with LVEF ≤35%, were included in the study. Transthoracic echocardiogram was performed in all patients, at moment of hospital admission and at discharge; transesophageal echocardiogram was performed during the procedure. We recorded the LVEF by modified Simpson’s rule. Periprocedural hemodynamic parameters were also recorded. 59 patients received Levosimendan during and early after the procedure (L-group) and 40 patients did not (no-L-group). Levosimendan perfusion was started at 0.01 μg/kg/min 1 h before the procedure without a loading dose, and maintained for 12h, according to hemodynamics.
Results
In the overall population, patients suffered from a severe reduction of LVEF (29.5 ± 5.3%) and high systolic pulmonary arterial pressure (sPAP) (51 ± 14.2 mmHg), without significant difference between the two groups. Acute procedural success was achieved in 98% of the study population, with 2 procedural failures in no-L-group (p = 0.16). During the procedure we observed a significant improvement of LVEF compared to baseline values only in L-group (from 29.6 ± 5.7% to 32.1 ± 7.6%, p = 0.046); in no-L-group the LVEF improved from 29.4 ± 5% to 30.2 ± 4.9% (p = 0.47); at discharge the LVEF was 31.3 ± 4.9% and 30.8 ± 5.7%, in L-group and no-L-group, respectively (p = ns compared to baseline and procedure). At discharge the sPAP significantly reduced in the overall population to 46.3 ± 12.7 mmHg (p 0.015): from 50.8 ± 12.3 mmHg vs 48.7 ± 11.9 in L-group (p = 0.35); from 51.2 ± 16 to 44.3 ± 13.2 mmHg (p = 0.04) in no-L-group. In-hospital mortality was 1.7% in L-group (1 patient die) and 0% in no-L-group. No relevant arrhythmias were reported in any patient during the hospital recovery.
Conclusion
In MitraClip patients with severe reduction of LVEF, Levosimendan has proven to improve hemodynamic outcome, increasing myocardial contractility during and early after procedure.

Abstract
Abstract
BACKGROUND
Early structural valve deterioration (SVD) frequently occurs in Mitroflow aortic bioprosthesis, especially for small sizes (19-mm and 21-mm), and it is associated with reduced overall survival. Treatment by percutaneous valve-in-valve (ViV) implantation is considered a challenging procedure. This is mainly due to an elevated risk of coronary ostia obstruction and high residual post-procedural mean gradients (mG), particularly when severe pre-existing patient-prosthesis mismatch (PPM) is present.
PURPOSE
Aim of our study was to assess the feasibility of transfemoral ViV in small Mitroflow aortic valves using supra-annular self-expanding valves, named CoreValve and Evolut R and Acurate neo and report the midterm clinical results by comparing serum natriuretic peptide type B levels (BNP) before the procedure and at a mean follow-up of 2 years.
METHODS
This is an observational study including 11 patients with stenotic-type SVD of small Mitroflow aortic valves, considered at high/prohibitive risk for surgical reoperation, who underwent ViV implantation between July 2012 and March 2018. We performed echocardiographic assessment of valve hemodynamics (according to VARC-2 definitions) before and after the procedure and during the follow-up. We used the BNP ratio (the ratio between measured serum BNP/NT-proBNP level and maximal normal level) to compare BNP results before the procedure and at follow-up. All-cause mortality during the hospitalization and follow-up was also reported.
RESULTS
The Mitroflow size was 19-mm in 4 patients and 21-mm in 7 patients. Pre-existing severe PPM was present in 4 patients and moderate PPM in 7. CoreValve 26 was implanted in 2 patients, EvolutR 23 in 5 and Acurate neo S in 4 patients. We reported no coronary obstruction, deaths or other major events during the hospitalization. At a mean follow-up of 2 years one patient died. The baseline aortic mG of 56 ± 19 mmHg has significantly reduced after the procedure to 16,6 ± 8 mmHg (p < 0.0001) and follow-up 29,6 ± 16 mmHg (p = 0.008). A post-procedural mG≥20, but <40 mmHg, was observed in 3 patients. BNP ratio at baseline was 14,6 ± 12; only one patient had a BNP ratio <3. At follow-up (n = 7 patients), BNP ratio was significantly lowered to 1,5 ± 1,08 (p = 0.01) with only one patient with a BNP ratio >3. Patients with mPG ≥20 mmHg did not show differences in terms of mortality and reduction of serum BNP levels.
CONCLUSIONS
In our experience the ViV procedure on small degenerated aortic Mitroflow bioprosthesis appears to be technically feasible and provides good midterm clinical results with a net reduction in serum BNP levels, although an increase in mG was observed. Even though a post-procedural mG ≥20 mmHg is considered indicative of suboptimal aortic valve hemodynamics (according to VARC-2 criteria), its correlation with worse outcomes remains unclear and deserves further investigations.

Abstract
Abstract
Background
Chronic kidney disease (CKD) has been shown to impact negatively the prognosis of patients with heart failure, coronary artery or valvular heart disease and emerged as predictor of poor outcomes in mitraclip population.
Purpose
Aim of our study was to evaluate three-year echocardiographic outcomes in CKD patients with severe mitral regurgitation (MR) treated with mitraclip.
Methods
This in an observational study including patients treated with mitraclip in our institution, who completed three years of follow up. Patients population was divided into two groups according to basal creatinine clearance (CrCl): group A, including patients with normal/mild decline of renal function (CrCl > 60 ml/min) and group B, including patients with CKD (CrCl < 60 ml/min). Demographic and procedural characteristics were compared, as well as echocardiographic data, including grade of MR, left ventricular ejection fraction (LVEF), mean transmitral gradient and systolic pulmonary artery pressure (sPAP). Kaplan-Meier survival curves were obtained.
Results
The study population consists of 107 patients (mean age 71 ± 9 years, 69% male): 57 belonging to group A and 50 to group B. Patients of group B had higher values of LogEuroScore (22 ± 10 vs.15 ± 9 p = 0,0002), systemic hypertension (92% vs. 74%, p = 0,026), complicated diabetes (46% vs. 24% p = 0,034) and NYHA IV before the procedure (24% vs 9 %, p = 0,059). Additionally, patients of group B had lower baseline LVEF (35 ± 11 vs. 41 ± 13; p = 0,012). Procedural success was similar between the two groups without significant difference in degree of MR reduction after mitraclip implantation. Echocardiographic follow-up showed that in group B, the LVEF did not improve after the treatment (more than 50% had LVEF < 35% at 1,2 and 3 years) while in the group A it improved significantly (LVEF < 35% from 47,6% at discharge to 29%, 32% and 31% at 1, 2 and 3 years, respectively). In comparison to group A, in group B a progressive increase in residual MR grade was observed (moderate-to-severe MR from 2% at discharge to 14%, 15%, and 27% at 1, 2 and 3 years, respectively) as well as in the mean transmitral gradient (from 3,90 ±1,6 mmHg after the mitraclip implantation to 5,28 ± 1,7; 5,73 ± 1,75; 6,06 ±1,75 at 1, 2 and 3 years, respectively) and sPAP (from 47 ± 12 mmHg at discharge to 49 ± 21; 51 ± 20; 48 ± 22 at 1, 2 and 3 years, respectively). Kaplan Meier estimate of survival free from in-hospital readmission was 77% in group A and 61% in group B (Log-Rank 4.563, p = 0,033) and survival free from cardiovascular death was 95% and 81,5%, in group A and B, respectively (Log-Rank 4.806, p = 0,028).
Conclusion
Our results suggest that CKD patients have poorer outcomes after mitraclip implantation with worsening of some echocardiographic parameters, particularly for residual MR degree, mean transmitral gradient and sPAP, without improvement in LVEF at one, two and three years of follow-up.

Abstract
Abstract
INTRODUCTION
Lactobacillus species are rare human pathogens but have been implicated in a variety of infections, including bacteremia and endocarditis, with Lactobacillus casei and Lactobacillus rhamnosus among the most frequently isolated species. Endocarditis due to Lactobacillus represents <0.5% of all cases of endocarditis and are associated with structural heart diseases, recent surgery, extended antibiotic and probiotic use and immuno-deficiency. We report a case of Lactobacillus plantarumendocarditis in a patient with biological aortic prosthetic valve.
CASE REPORT
Our patient is a 48 year-old male with a past medical history of surgical aortic replacement with a biological prosthetic valve in 2013. He reports the onset of symptoms 4 months before with worsening asthenia. The patient presented to a cardiologist after 3 months from symptoms beginning. A transesophageal echocardiogram (TEE) described marked fibro-plastic thickening of the cusps with two elongated vegetations (12 mm and 7 mm) causing a moderate-to-severe aortic steno-regurgitation. A few days later he came to our emergency department. On admission, the patient was afebrile, eupnoeic on room air. The cardiac examination revealed a regular rate and rhythm with a grade 4 of 6 holosystolic murmur loudest at the aortic and pulmonary focus. Three sets of blood cultures were drawn on admission. Hence, he was transferred to the Infectious Diseases Department where he started antibiotic therapy with Ceftriaxone and Gentamicin. A 18F-FDG PET-CT total body showed tracer accumulation close to the prosthetic aortic valve. Few days later Lactobacillus Plantarum was isolated from blood cultures and, according to the antibiogram results, therapy was adjusted using G Penicillin, Vancomicyn and Gentamicin. The TEE, performed during the hospitalization, showed one mobile vegetation, reduced in size (5 mm), adherent to the anterior aortic cusp, which prolapsed in the left ventricular outflow tract and commissural fusion, causing severe steno-regurgitation (Gmax 84 mmHg, Gmed 54 mmHg). During hospitalization the serial blood cultures resulted negative. Serial TEEs were also performed (3rdand 6thweek), showing a gradual reduction of the cusps thickening and disappearance of commissural fusion (Figure). In the last TEE no vegetations were described, and the transaortic mean gradient was reduced (Gmed 38 mmHg), persisting severe regurgitation. Hence the patient was discharged with oral antibiotic therapy (amoxicillin and clavulanic acid) and indication to redo aortic valve surgery. Written informed consent was obtained.
CONCLUSIONS
L. plantarum is a rare form of endocarditis. In our patient it caused fibro-plastic thickening of the bioprosthesis cusps and commissural fusion, determining severe steno-regurgitation. It also responded to targeted antibiotic therapy with improvement in cusp mobility but persistence of severe regurgitation.

Abstract
INTRODUCTION Venetoclax, an orally bioavailable inhibitor of BCL-2, was approved in 2016 by the United States Food and Drug Administration (FDA) for the treatment of chronic lymphocytic leukemia (CLL) patients with 17p deletion [del(17p)], who have received at least one prior therapy. Areas covered: We focus on the mechanism of action of venetoclax and on the clinical trial data that led to the approval of venetoclax for CLL patients. We also review the studies in which this drug has being explored in combination with other anti-CLL drugs. Expert opinion: Data from early clinical trials have shown that venetoclax, as a single agent, is highly effective for relapsed/refractory CLL patients, including those cases with high-risk features. Furthermore, venetoclax seems to be an appropriate option for patients who progress on B-cell receptor (BCR) pathway kinase inhibitors. Venetoclax is also safe, with the most common serious adverse events being neutropenia. The risk of tumor lysis syndrome (TLS) can be reduced by a slow dose ramp-up, careful monitoring, and adequate prophylaxis. Ongoing trials will further clarify the safety and efficacy of venetoclax in combination with other drugs in both relapsed/refractory and untreated CLL patients.

Abstract
We describe the case of a patient with Philadelphia-positive acute lymphoblastic leukemia treated with dasatinib plus steroids as first-line therapy, who achieved a major molecular response (MMR) before undergoing matched, unrelated donor allogeneic stem cell transplant. Eleven months after the transplant, she experienced molecular relapse. Mutational screening showed negativity for the T315I mutation, The patient underwent a salvage chemotherapy regimen with clofarabine + cyclophosphamide + steroids and ponatinib (clofarabine 70 mg i.v., days 1-5, cyclophosphamide 700 mg i.v., days 1-5, and ponatinib 45 mg p.o., daily starting at day 15). We observed a rapid decrease in minimal residual disease on molecular assessment with an MMR of P190-BCR-ABL/ABL = 0.01% confirmed by bone marrow revaluations at days +23, +59, +108, and +191 after the first day of salvage chemotherapy. After starting ponatinib, the patient experienced skin graft-versus-host disease, suggesting that the efficacy of ponatinib could be related not only to the direct antileukemic effect but also to its ability to promote an indirect graft-versus-leukemia effect. Ponatinib treatment was well tolerated and considered safe with easily manageable side effects.

Lenalidomide and low-dose dexamethasone (Rd) versus bortezomib, melphalan, prednisone (VMP) in elderly newly diagnosed multiple myeloma patients: A comparison of two prospective trials. Am J Hematol 2017; 92:244-250. [PMID: 28006855 DOI: 10.1002/ajh.24621] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Revised: 11/30/2016] [Accepted: 12/07/2016] [Indexed: 11/10/2022]
Abstract
There are currently no direct head-to-head clinical trials evaluating bortezomib-melphalan-prednisone (VMP) versus lenalidomide and low-dose dexamethasone (Rd). VMP (257 cases) and Rd (222 cases) arms of two randomized phase III trials were employed to assess the treatment influence on outcome in untreated elderly MM patients. Progression free survival (PFS) and overall survival (OS) were the primary and secondary end-points, respectively, and were investigated according to treatments administered over a 60-months follow-up period. While VMP significantly reduced the disease progression rate between enrolment and 12 months of follow-up, no difference between the two schedules was found between 12 and 32 months. After 32 months, Rd-treated patients had a lower incidence of disease progression. A statistically significant higher OS rate was seen in the VMP arm, which was maintained after data adjustment for potential confounders. Both approaches showed acceptable toxicity profiles. The profound tumor reduction by VMP over Rd justifies the initial higher PFS rate in favor of the bortezomib schedule, while the Rd regimen overcomes this evident initial drawback in reducing the tumor burden by long-term drug administration, gaining a subsequent improved disease control. VMP is associated with a significant reduced risk of death. This study may help physicians make a more informed therapy choice.

Clinical relevance of hypogammaglobulinemia, clinical and biologic variables on the infection risk and outcome of patients with stage A chronic lymphocytic leukemia. Leuk Res 2017; 57:65-71. [PMID: 28292720 DOI: 10.1016/j.leukres.2017.02.011] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2016] [Revised: 02/06/2017] [Accepted: 02/26/2017] [Indexed: 01/05/2023]
Abstract
The prognostic effect of hypogammaglobulinemia (HGG), clinical and biologic characteristics on the infection risk and outcome has been retrospectively analyzed in 899 patients with stage A chronic lymphocytic leukemia (CLL). Low levels of IgG were recorded in 19.9% of patients at presentation, low levels of IgM and/or IgA in 10.4% and an additional 20% of patients developed HGG during the course of the disease. Before the start of any treatment, 160 (12.9%) patients experienced at least one grade ≥3 infection requiring a systemic anti-infective treatment and/or hospitalization. While IgG levels at diagnosis were not associated with an increased risk of grade ≥3 infection or with an adverse outcome, a significantly increased rate of grade ≥3 infections was recorded in patients with unmutated IGHV (p=0.011) and unfavorable FISH aberrations (p=0.009). Late onset HGG, more frequently recorded in patients with Rai stage I-II (p=0.001) and unmutated IGHV (p=0.001), was also associated with a higher rate of severe infections (p=0.002). These data indicate that, stage A patients with clinical and biologic characteristics of a more aggressive disease develop more frequently late onset HGG, grade ≥3 infections and require a closer clinical monitoring.

Abstract
Here we describe the case of a 61-year-old woman who developed chronic myeloid leukaemia in chronic phase under treatment with antiaritmic-therapy (amiodarone) for Parossistic Sopraventricular Tachycardia (PSVT). Initially the patient started with imatinib at standard dose of 400 mg/day but after 6 months of treatment she reached only a Minor Cytogenetic Response (“sub-optimal response”, according to European LeukaemiaNet criteria 2006). After 9 months, she was still in a Minor Cytogenetic Response. We therefore performed a mutation screening analysis that highlighted T240S, N322S, T406A, Y435N mutations. The patient switched to nilotinib at the dose of 800 mg day: Complete Cytogenetic Response and Major Molecular Response were reached after 3 months. Nilotinib was safely administered without further QTc prolongation or haematologic and extrahaematologic adverse side effects.

Abstract
BACKGROUND A combination of bortezomib (1.3 mg/m(2)), melphalan (5 mg/m(2)), and dexamethasone (40 mg) (BMD), with all three drugs given as a contemporary intravenous administration, was retrospectively evaluated. PATIENTS AND METHODS Fifty previously treated (median 2 previous lines) patients with myeloma (33 relapsed and 17 refractory) were assessed. The first 19 patients were treated with a twice-a-week (days 1, 4, 8, 11, 'base' schedule) administration while, in the remaining 31 patients, the three drugs were administered once a week (days 1, 8, 15, 22, 'weekly' schedule). RESULTS Side-effects were predictable and manageable, with prominent haematological toxicity, and a better toxic profile in 'weekly' schedule (36% versus 66% in 'base' schedule). The overall response rate was 62%. After median follow-up of 24.5 months (range 2.7-50 months), the median progression-free survival (PFS) was 21.6 with no difference between the two schedules and the median overall survival (OS) was 33.8 months. Independently from the adopted schedule, we found that also in a cohort of relapsed/refractory patients achieving at least partial remission improved PFS (35.2 versus 9 months) and OS (unreached median versus 18 months). CONCLUSION Taken together, our observations suggest that BMD is an effective regimen in advanced myeloma patients with acceptable toxicity.

Abstract
Orbital rhabdomyosarcoma accounts for one-fourth of the primary tumors in the head and neck region. Modern treatment modalities have led to a 2-year survival rate of about 90% in these patients. However, new therapeutic trials are designed to reduce complications and salvage more than 90% of orbital cases. Between 1979 and 1990, 12 children affected by primary orbital rhabdomyosarcoma have been diagnosed and treated at the University of Naples. Ten of them have been uniformly treated by biopsy, followed by immediate radiation and combined chemotherapy. All 12 patients are alive and free of detectable disease, from a minimum of 7 months to a maximum of 123 months after diagnosis. In all children, ocular structures have been spared and the complications observed until now have been few. The above results suggest that the association of immediate radiation therapy and chemotherapy might represent an optimal tool for treatment of orbital rhabdomyosarcoma.
