Abstract: To assess the proportion of women with gestational diabetes (GDM) by performing postpartum Oral Glucose Tolerance Test (OGTT) and to identify GDM phenotypes at high-risk of postpartum dysglycemia (PPD). Methods Observational, retrospective, multicenter study involving consecutive GDM women. Recursive partitioning (RECPAM) analysis was used to identify distinct and homogeneous subgroups of women at different PPD risk. Results From a sample of 2,736 women, OGTT was performed in 941 (34.4%) women, of whom 217 (23.0%) developed PPD. Insulin-treated women having family history of diabetes represented the subgroup with the highest PPD risk (OR 5.57, 95% CI 3.60–8.63) compared to the reference class (women on diet with pre-pregnancy BMI  〈   = 28.1 kg/m 2 ). Insulin-treated women without family diabetes history and women on diet with pre-pregnancy BMI  〉  28.1 kg/m 2 showed a two-fold PPD risk. Previous GDM and socioeconomic status represent additional predictors. Fasting more than post-prandial glycemia plays a predictive role, with values of 81–87 mg/dl (4.5–4.8 mmol/l) (lower than the current diagnostic GDM threshold) being associated with PPD risk. Conclusions Increasing compliance to postpartum OGTT to prevent/delay PPD is a priority. Easily available characteristics identify subgroups of women more likely to benefit from preventive strategies. Fasting BG values during pregnancy lower than those usually considered deserve attention.

Abstract: In acute lymphoblastic leukemia, flow cytometry detects more accurately leukemic cells in patients' cerebrospinal fluid compared to conventional cytology. However, the clinical significance of flow cytometry positivity with a negative cytology - occult central nervous system disease - is not clear. In the framework of the national Campus ALL program, we retrospectively evaluated the incidence of occult central nervous system disease and its impact on outcome in 240 adult patients with newly diagnosed acute lymphoblastic leukemia. All cerebrospinal fluid samples were investigated by conventional cytology and flow cytometry. The presence of ≥10 phenotypically abnormal events, forming a cluster, was considered as flow cytometry positivity. No central nervous system involvement was documented in 179 patients, while 18 were positive by conventional morphology and 43 were occult central nervous system disease positive. The relapse rate was significantly lower in central nervous system disease negative patients and the disease-free and overall survival were significantly longer in central nervous system disease negative patients than in those with manifest or occult central nervous system disease positive. In multivariate analysis, the status of manifest and occult central nervous system disease positivity was independently associated with a worse overall survival. In conclusion, we demonstrate that in adult acute lymphoblastic leukemia patients at diagnosis flow cytometry can detect occult central nervous system disease at high sensitivity and that the status of occult central nervous system disease positivity is associated with an adverse outcome.

Abstract: The outcome of relapsed or refractory (R/R) T‐cell acute lymphoblastic leukemia/lymphoma (T‐ALL/T‐LBL) in adults is poor, with less than 20% of patients surviving at 5 years. Nelarabine is the only drug specifically approved for R/R T‐ALL/T‐LBL, but the information to support its use is based on limited available data. The aim of this observational phase four study was to provide recent additional data on the efficacy and safety of nelarabine in adults with R/R T‐ALL/T‐LBL and to evaluate the feasibility and outcome of allogeneic hematopoietic stem cell transplant (SCT) after salvage with nelarabine therapy. The primary endpoints were overall response rate (ORR) and overall survival (OS). Additional endpoints were safety, SCT rate and post‐SCT OS. Between May 2007 and November 2018, 118 patients received nelarabine salvage therapy at 27 Italian hematology sites. The median age was 37 years (range 18‐74 years), 73% were male, 77 had a diagnosis of T‐ALL and 41 of T‐LBL, and 65/118 (55%) had received more than two lines of therapy. The median number of nelarabine cycles was two (range 1‐4); 43/118 (36%) patients had complete remission (CR), 16 had partial remission (14%) and 59 (50%) were refractory, with an ORR of 50%. The probability of OS, from the first dose of nelarabine, was 37% at 1 year with a median survival of 8 months. The OS at 1 year was significantly better for the 47 patients (40%) who underwent SCT after nelarabine salvage therapy (58% vs 22%, log‐rank P 〈  .001). The probability of OS at 2 and 5 years from SCT was 46% and 38%, respectively. Seventy‐five patients (64%) experienced one or more drug‐related adverse events (AE). Grade III‐IV neurologic toxicities were observed in 9/118 (8%) of cases and thrombocytopenia or/and neutropenia (grade III‐IV) were reported in 41% and 43% of cases, respectively. In conclusion, this is one of the largest cohorts of adult patients with R/R T‐ALL/T‐LBL treated in real life with nelarabine. Taking into account the poor prognosis of this patient population, nelarabine represents an effective option with an ORR of 50% and a CR rate of 36%. In addition, 40% of cases following nelarabine salvage therapy could undergo SCT with an expected OS at 2 and 5 years of 46% and 38%, respectively. The safety profile of nelarabine was acceptable with only 8% of cases showing grade III‐IV neurological AE.

Abstract: Introduction. In a modern context of improved management of acute lymphoblastic leukemia (ALL), central nervous system (CNS) involvement at diagnosis remains an obstacle towards long-term cure. We have previously reported that flow cytometry (FCM) is better than conventional cytology (CC) in demonstrating the presence of leukemic cells in patients' (pts) cerebrospinal fluid (CSF), especially in samples with low cell counts. In the framework of the national Campus ALL program aimed at improving the management of adult ALL patients enrolled in the GIMEMA protocols, we retrospectively evaluated the incidence of occult CNS positivity and its impact on outcome in 221 adult pts with newly diagnosed ALL from 11 centers. Methods. Ninety-four patients (42%) were females and 127 (58%) males, with a median age of 44 years (range 17-80), a median white blood cell (WBC) count of 10.6x109/L (range 0.1-457). One hundred and seventy pts (77%) had B-lineage ALL. Cytogenetic/genetic data were available in 167 (75%) pts: 58 (35%) had a BCR/ABL rearrangement, 14 (8%) a complex karyotype and 11 (6%) a MLL rearrangement. Pts were treated according to the GIMEMA/NILG ALL protocols or with the Hyper-CVAD program. Ninety-eight pts underwent an allogeneic stem cell transplant (ASCT). Median follow up was 26.8 months (range 1-136.6). All CSF samples were evaluated both by CC and FCM. The presence of ≥10 clonally restricted or phenotypically abnormal events was regarded as a FCM positivity. Based on the results of CSF examination, three different categories were recognized: manifest CNS+ (CC+FCM+), occult CNS+ (CC-FCM+) and CNS- (CC-FCM-). Results. Overall, 16 (7%) pts had manifest CNS+, 39 (17%) occult CNS+ and 166 (75%) were CNS-Median age, WBC count, B/T lineage, cytogenetic/genetic features did not differ significantly between the three categories. A complete remission (CR) was achieved in 178 (80%) pts, 9 (4%) died early in induction and 104/178 (58%) experienced a relapse. The frequency of CR rate did not vary significantly across the three identified categories. In univariate analysis, the CNS status correlated significantly with the incidence of relapse (p=.004) and with censor ( 〈 .00002). The four-year overall survival (OS) for manifest CNS+, occult CNS+ and CNS- pts was 6%, 17% and 46%, respectively (p=.0007) (Figure). No difference in terms of OS was observed between manifestand occult CNS+ pts (p=.30). In multivariate analysis a baseline status of manifestor occult CNS+ (RR: 1.98, 95%CI 1.47-2.43, p=0.00001) and age 〉 45 years (RR:1.45, 95% CI 1.47-2.43, p=0.04)were independently associated with a lower OS. Conclusions. Our large, multicenter CAMPUS ALL study showed that i) in ALL adult pts, FCM allows to detect occult CNS disease, even in conditions of low spinal fluid leukemic count; ii) the presence of occult CNS disease is associated with an unfavorable outcome. Further prospective studies on larger series are needed to confirm these data. Figure. Figure. Disclosures Del Principe: Gilead: Membership on an entity's Board of Directors or advisory committees.

Abstract: Hairy cell leukemia variant (HCLv) is a provisional disease in the 2016 WHO classification of lymphomas, characterized by unfavorable prognosis and early relapse following conventional purine analog‐based regimens. In this study, we report 2 patients with relapsed HCLv treated with ibrutinib. The first patient achieved a partial response following ibrutinib treatment and received the drug for 16 months, without severe adverse events. However, at disease progression venetoclax was not clinically active. The second patient discontinued the drug early due to intolerance. Ibrutinib was active in our patients with HCLv and deserve further investigations.

Abstract: Secondary antibody deficiency (SAD) is a common complication in chronic lymphocytic leukemia (CLL) which favors the development of life-threatening infections. Subcutaneous immunoglobulins (IG) (SCIG) have been proven to be as effective as intravenous immunoglobulin (IVIG) in primary immunodeficiencies. Since only a few studies investigated SCIG in secondary antibody deficiency, the aim of this study was to assess the efficacy and safety of SCIG or IVIG in CLL patients with secondary antibody deficiency. One hundred and sixteen CLL patients were recruited, 63% were males, and the median age was 68 years; 44% had bronchiectasis and 76% never smoked. Forty-nine patients received IVIG and 88 SCIG, including 28 patients who shifted from IVIG to SCIG. Despite similar baseline IgG levels, patients receiving SCIG achieved higher IgG after at least +6 months (p = 0.0009). We observed that SCIG can decrease the cumulative incidence of first (HR 0.39 p 〈 0.0001) and second (HR 0.56 p = 0.0411) infection more than IVIG. The effect was remarkable in that patients were able to reach at least 6 g/L of IgG after 6 months of treatments (p 〈 0.0001). Replacement therapies were well tolerated with less adverse events and a lower discontinuation rate in patients was managed with SCIG than IVIG. In this study we describe the clinical features of a large cohort of CLL with secondary antibody deficiency receiving IG. We demonstrated that SCIG are active and well tolerated drugs that allows to reach higher IgG levels and decrease the rate of infections better than IVIG, in particular when IgG levels reach 6 g/L.

Abstract: INTRODUCTION. Richter syndrome (RS), the transformation of chronic lymphocytic leukemia (CLL) into an aggressive lymphoma, is a rare but a life threatening complication. Complex karyotype (CK), defined by the presence of ≥3 chromosomal lesions, is a heterogeneous cytogenetic category associated with a shorter survival in CLL, but its impact on the evolution into a RS has not been investigated. Among CK cases, those with≥5 lesions (highCK) and those with major structural abnormalities [type-2 CK (CK2)] display a more aggressive clinical course. The aim of this study was to assess the impact of CK subtypes on the risk of CLL evolution into a RS. METHODS. We performed a retrospective study in 3 Italian CLL centers. Stimulated cytogenetic with CpG+IL2 was performed in 540 patients within the first year after CLL diagnosis. CK cases with unbalanced translocations, additions, insertions, derivative or marker chromosomes were classified as type-2 CK (CK2). Instead, high-CK cases were those presenting at least 5 chromosome abnormalities. An IGHV gene sequence homology ≥98% was considered as unmutated (U-IGHV), as opposed to mutated (M-IGHV). TP53 disruptions (TP53dis) included deletions and/or mutations. Time to Richter syndrome (TTRS) was calculated from CLL diagnosis to either histologically confirmed diffuse large B-cell lymphoma transformation or last known follow-up visit. Survival curves were compared with the log-rank test and p & lt;0.05 was considered as significant. Hazard ratio (HR) was calculated by multivariate analysis. RESULTS. Among the 540 patients, the median age at diagnosis was 63±12 years, 61% were males, 76% were at Binet stage A, 52% were U-IGHV, 11% had TP53dis, 20% harbored a CK. According to the qualitative classification of CK subtypes, 78/107 (73%) were CK2, whereas, with regards to the number of chromosome lesions, 52/107 (49%) were classified as high-CK. High-CK was present in 63% of CK2 patients. Seventeen % of patients died and 5% developed a RS over a median follow-up of 7 years. Overall, the rate of RS after 5 and 10 years from the diagnosis of CLL was 2.6% and 12%. We observed that patients who developed a RS were more commonly at a more advanced Binet stage at CLL diagnosis (46% vs 23%, p=0.0113) and displayed more frequently an U-IGHV status (79% vs 56%, p=0.0191), TP53 abnormalities (32% vs 10%, p=0.0043), CK2 (46% vs 13%, p & lt;0.0001) and a high-CK (39% vs 8%, p & lt;0.0001) profile, as compared to patients who did not developed RS. By univariate and multivariate analysis, the presence of a CK (overall), of a CK2 and of a high-CK subtypes were all significantly associated with a shorter TTRS, together with U-IGHV status, TP53dis, 11q- by FISH and Binet stage B-C. Patients with a CK2 (HR=5.6 p & lt;0.0001) and/or a high-CK (HR=6.9 p & lt;0.0001) harbored the highest risk of developing a RS, with a 10-year TTRS of 38% and 41%, respectively, vs 8% of patients without a CK. Other variables associated with TTRS at univariate and multivariate analysis were Binet stage B-C, U-IGHV, 11q-, TP53 dis. By integrating the statistically significant variables, we developed a hierarchical model based on HR values (Figure 1): 15% of patients were classified as high-CK and/or CK2, for whom the 10-year TTRS was 31% and the HR 13; 45% were U-IGHV/TP53dis/11q-/Binet B-C and showed a 10-year TTRS of 12% and the HR 3; 40% were M-IGHV without CK and TP53 wild-type, the 10-year TTRS was only 3%. This model was confirmed in multivariate analysis and internally validated (p & lt;0.0001). Moreover, our RS scoring system prove to better forecast the risk to develop RS that the hierarchical FISH score, the CLL-IPI and the Barcelona-Brno score, based both lower prediction error and Akaike index. CONCLUSIONS. We herein identified variables associated with a higher risk of developing a RS and recapitulated them into a RS scoring system. Remarkably, patients harboring a CK subtype at CLL diagnosis have the highest risk of developing a RS and should be carefully monitored during the clinical follow-up.

Abstract: BACKGROUD. The B-cell receptor inhibitor ibrutinib has significantly improved treatment and overall management of chronic lymphocytic leukemia (CLL). Although several data derived from clinical trials suggest that ibrutinib increases the risk of atrial fibrillation (AF), the incidence of AF in a real-life cohort of CLL patients is unknown. Furthermore, it would be clinically relevant to identify patients at high risk of AF during ibrutinib. The aim of this study is to report the prevalence and risk factors of AF in ibrutinib-naive CLL, in order to define a predictive model for the development of AF and to test it in a cohort of subjects receiving ibrutinib. METHODS. We retrospectively analyzed data from 860 ibrutinib-naive CLL patients, referred to the Padua University hospital. Comorbidities, clinical and biological prognostic markers were analyzed using the Mann-Whiney, Fisher exact or Chi-square tests, when appropriated. Time to AF (TTAF) and overall survival (OS) were evaluated with Kaplan-Meier method. Univariate and multivariate Cox models were run to identify independent factors associated with AF. Then, risk values were obtained based on the hazard ratios. The score for AF was calculated as the sum of each risk values. Subsequently, the model was evaluated in a cohort of 354 ibrutinib-treated patients referred from 8 Italian hematological centers. RESULTS. Among the 860 patients from Padua hospital, 60% were male, 49% were older than 65 years, 73% were Binet A stage at diagnosis and 41% underwent at least one line of treatment. A prior history of AF was present in 21 patients (2.4%) at CLL diagnosis, while, among the remaining 839 patients without a previous history of AF, 47 (5.6%) developed it after a median follow-up of 9.4 years, resulting in an estimated incidence of almost 0.8% cases/year. Moreover, the median OS for patients with AF was significantly shorter than that patients without AF (12 vs 22 years, p 〈 0.0001). Based on univariate and multivariate analysis, variables associated with the risk of AF were: age 〉 65 years (p=0.001, 1 point), male gender (p=0.003, 1 point), valvular hearth diseases (p=0.001, 2 points), cardiopathy (p 〈 0.001, 3 points), hyperthyroidism (p=0.001, 1 point), chronic lung diseases (p=0.001, 1 point), diabetes mellitus (p=0.023, 1 point), severe infections (p=0.019, 1 point). As expected, no clinical and biological prognostic markers (i.e. Binet stage, IGHV mutation, TP53 abnormalities) for CLL were associated with an increased risk of AF. A predictive model was designed based on these factors and it stratified patients into 4 different groups. The estimated TTAF after 15 years of follow-up were 0%, 10%, 19% and 61% for patients with score 0, 1-2, 3-4, and ≥5 respectively (p 〈 0.001, Fig. 1A). Furthermore, it underwent internal validation using the bootstrap method. Subsequently, we applied our AF model to a cohort of 354 ibrutinib-treated patients, 64% were male, the median age was 69 years, 88 were treatment-naive, 70% U-IGHV and 39% harbored TP53 abnormalities. Forty-four subjects developed AF after a median observation of 25 months, with an estimated 2-year TTAF of 12%. Only 9 out of the 44 patients (20%) discontinued ibrutinib. Sixteen patients (4%) were classified as AF score 0, 218 (62%) score 1-2, 73 (21%) score 3-4 and 46 (13%) at least score 5. Our model was also able to identify patients at a higher risk AF during ibrutinib, in fact the 2-year risk of AF was 0%, 5%, 17% and 40% for patients with score 0, 1-2, 3-4, and ≥5 respectively (p 〈 0.001, Fig. 1B). Patients with a score of 5 or higher have a risk 20 times higher to developed AF than the other subjects (HR 19.6, 95% interval 7-52, p 〈 0.0001). So far, the OS of ibrutinib-treated patients with AF was not inferior to that of patients who did not developed AF (2-years OS 89% and 82%, respectively p=0.1252), but the median follow-up is only 2 years. CONCLUSIONS. In this study, variables associated with an increased risk of developing AF were identified and recapitulated into a scoring system. Our model proved to be a valid tool to identify patients at a higher risk of developing AF, including ibrutinib-treated patients. Taking these data into account, patients with a score ≥5 should be carefully monitored during ibrutinib treatment given the very high-risk of developing AF or should be considered for alternative therapies.

Abstract: BACKGROUND Chronic Lymphocytic Leukemia (CLL) is one of the most common hematological malignancies in Western countries. The disease is characterized by heterogeneous clinical course and outcome. During the last 15 years several clinical, biological and molecular prognostic factors have been identified, validated and some of them are currently used in patients' and treatment management. To improve the predictive accuracy of these markers, they have been combined into prognostic indexes (W. Wierda, JCO 2011, D. Rossi, Blood 2012, J. Bahlo, Haematologica 2015). Werecently proposed the Integrated CLL Scoring System (ICSS) based on cytogenetic abnormalities by FISH, IGHV mutational status and CD38 expression from 212 patients (A. Visentin et al, Clin Lymph Myeloma & Leuk 2015). The aim of this study was to validate the prognostic power of our index into a larger series of 420 CLL patients. METHODS 420 CLL patients referred to the Hematology Unit of Padua University Hospital from 1989 to 2015 were recruited in this study. According to ICSS, patients were classified as: low-risk, those patients with 13q deletion or normal FISH, IGVH mutated and CD38 〈 30%; high-risk, subjects with 17p or 11q deletion and/or IGVH unmutated and CD38 〉 30%; intermediate-risk, all remaining patients. Treatment free survival (TFS) was calculated as time from diagnosis to treatment (event), death or last known follow-up (censored). Overall survival (OS) was calculated from the date of diagnosis to death for any cause (event) or last known follow-up (censored). TFS and OS were compared with log-rank test and plotted using Kaplan-Meier method. The predictive accuracy of ICSS was evaluated by the Harrel's concordance index (c-index); a value 〉 0.5 implies a good predictive ability. RESULTS The median age of our cohort was 62 years; 64% were male and 85% were Binet stage A at diagnosis. Cytogenetic analysis by FISH showed that 41 patients harbored 17p deletion, 50 11q deletion, 236 13q deletion, 44 trisomy 12 and 49 had normal FISH. 236 (56%) patients had IGHV gene homology 〉 98% (i.e. mutated IGHV) and 103 (25%) expressed more then 30% of CD38. According to ICSS 202 (48%) subjects were classified as low-risk, 83 (20%) intermediate-risk and 135 (32%) high-risk. After a median follow-up of 81 months, the median TFS for ICSS classes of risk were 211, 70 and 27 months (log-rank test, p 〈 0.0001, Figure 1A). The estimated 10-year TFS were 61%, 37% and 10% for low, intermediate and high-risk patients. The median OS were 213 and 136 months for intermediate and high-risk, while it was not reached for low-risk patients (Log-rank test, p 〈 0.0001, Figure 1B). After 10 years from diagnosis the estimated OS were 88%, 79% and 57%, respectively. These data were confirmed by a multivariate analyses. In fact, high-risk patients had 5.3 and 4.0 times risk of start treatment and death than low-risk subjects, respectively (p 〈 0.0001). This model was statistically internally validated, showing c-indexed of 0.712 and 0.693 for TFS and OS, respectively. In multivariate analyses, variables confirmed to predict adverse prognosis were male gender (p=0.0183), age 〉 65years (p 〈 0.0001), Rai III-IV (p=0.0025), Binet C (p=0.0002), 17p deletion (p=0.0002), TP53 abnormalities (p=0.0051), unmutated IGVH (p 〈 0.0001), CD38 〉 30% (p=0.0044) and high-risk ICSS (p 〈 0.0001). CONCLUSIONS We herein provide evidence of the prognostic power and feasibility of ICSS into a large population of CLL patients. The use of this prognostic index could help physician into follow-up schedule, since high-risk patients should be monitored more often given the estimated increased risk of progression.
