RESUMEN

INTRODUCTION: Efficacy and safety of the fixed ratio combination of insulin degludec and liraglutide (IDegLira) has been largely documented. However, long-term data are limited. This study aimed at describing persistence in therapy and the effectiveness at 48 months of IDegLira. METHODS: We conducted an observational study based on retrospective chart review. All patients treated with IDegLira during 2018-2022 were included. Data on treatment approaches and clinical outcomes were collected at the first prescription of IDegLira (T0) and after 6, 12, 24, 36, and 48 months. RESULTS: Overall, 156 patients (mean age 68 years, 64.1% men) started IDegLira, of whom 88 (56.4%) were previously treated with basal-oral therapy (BOT) and 68 (43.6%) with basal-bolus schemes (BB). Before starting IDegLira, 23.8% were treated with ≥ 2 oral antihyperglycemic agents in association with insulin; at T0, the proportion decreased to 3.2%. Short-acting insulin was discontinued after the first week. After 48 months, levels of HbA1c were significantly reduced by 1.34% in the BOT group and 1.07% in the BB group (p < 0.0001 in both groups). In the BOT group, FBG levels decreased by about 50 mg/dl and body weight was unchanged. In the BB group, FBG levels decreased by about 40 mg/dl and body weight was significantly reduced by an average of 7.7 kg. Five patients (3.2%) interrupted therapy with IDegLira during 48 months, and no severe hypoglycemia occurred. CONCLUSIONS: Our study emphasizes the important role of IDegLira in maintaining a good metabolic control while minimizing the risk of major hypoglycemia and weight gain in the long term. The substantial simplification of treatment schemes can increase adherence.

RESUMEN

Dysregulated nuclear-cytoplasmic trafficking has been shown to play a role in oncogenesis in several types of solid tumors and hematological malignancies. Exportin 1 (XPO1) is responsible for the nuclear export of several proteins and RNA species, mainly tumor suppressors. KPT-330, a small molecule inhibitor of XPO1, is approved for treating relapsed multiple myeloma and diffuse large B-cell lymphoma. Cutaneous T-cell lymphoma (CTCL) is an extranodal non-Hodgkin lymphoma with an adverse prognosis and limited treatment options in advanced stages. The effect of therapeutically targeting XPO1 with KPT-330 in CTCL has not been established. We report that XPO1 expression is upregulated in CTCL cells. KPT-330 reduces cell proliferation, induces G1 cell cycle arrest and apoptosis. RNA-sequencing was used to explore the underlying mechanisms. Genes associated with the cell cycle and the p53 pathway were significantly enriched with KPT-330 treatment. KPT-330 suppressed XPO1 expression, upregulated p53, p21WAF1/Cip1, and p27Kip1 and their nuclear localization, and downregulated anti-apoptotic protein (Survivin). The in vivo efficacy of KPT-330 was investigated using a bioluminescent xenograft mouse model of CTCL. KPT-330 blocked tumor growth and prolonged survival (p < 0.0002) compared to controls. These findings support investigating the use of KPT-330 and next-generation XPO1 inhibitors in CTCL.

RESUMEN

Nearly a billion people worldwide are infected with the hepatitis B Virus (HBV) and about a third of them have chronic infection. HBV is an important cause of morbidity and mortality, including acute and chronic hepatitis and hepatocellular carcinoma (HCC). Screening and control of primary HBV infection through vaccination represent a major advance in global public health, but large sections of the world population, in both developed and underdeveloped countries, remain unscreened and unvaccinated. In addition to being a global cause of liver disease, an important role of HBV in lymphoma has also emerged. First, the high risk of HBV reactivation in previously infected patients receiving chemo-immunotherapy necessitates the systematic evaluation of HBV serological status in all non-Hodgkin's lymphoma (NHL) cases and preemptive antiviral therapy for those who may have chronic or occult HBV infection. Second, HBV has been shown to infect lymphocytes, namely B-cells, and has been associated with a higher risk of developing B-cell lymphoma, most clearly in countries where HBV is endemic. While the risk of HBV reactivation with chemoimmunotherapy in NHL is well known, the role and the impact of HBV as a global lymphoma risk factor and potential oncogenic driver in B-cells are very poorly understood. Here, we review the clinical and scientific evidence supporting an association between HBV and B-cell lymphoma, with a particular focus on diffuse large B-cell lymphoma (DLBCL) and provide an overview of the estimated impact of HBV infection on the biology and clinical course of DLBCL. We also discuss ways to gain a better insight into the unmet need posed by HBV in lymphoma and whether assessing immune responses to HBV, measuring viral loads, and detecting the presence of HBV-encoded proteins in tumor tissue could be integrated into the molecular and clinical risk stratification of patients with DLBCL.

RESUMEN

Cytokines are a vital component of the immune system that controls the activation and growth of blood cells. However, chronic overexpression of cytokines can trigger cellular events leading to malignant transformation. The cytokine interleukin-15 (IL-15) is of particular interest, which has been shown to contribute to the development and progression of various hematological malignancies. This review will provide an overview of the impact of the immunopathogenic function of IL-15 by studying its role in cell survival, proliferation, inflammation, and treatment resistance. We will also review therapeutic approaches for inhibiting IL-15 in blood cancers.

RESUMEN

INTRODUCTION: To complement results of the SUSTAIN program, this study assessed effectiveness and safety of once weekly subcutaneous semaglutide in people with type 2 diabetes (T2D) managed under routine care. METHODS: This was a multicenter, observational, retrospective study including all patients treated with semaglutide. Changes in clinical outcomes from baseline to 6 and 12 months were assessed in patients who were glucagon-like peptide receptor agonist (GLP-1RA) naïve or switching from another GLP-1RA. Discontinuation rate was assessed. RESULTS: Overall, 216 patients (mean age 64 years, 65.7% men) were evaluated: 135 (61.5%) naïve and 81 (38.5%) switchers from another GLP-1RA. In the naïve cohort, after 6 months from semaglutide initiation, levels of HbA1c significantly decreased by - 1.31% (p < 0.0001). All obesity indices improved, with mean reductions in body weight of - 3.92 kg, in BMI of - 1.43 kg/m2, and in waist circumference of - 5.03 cm. In the switcher cohort, statistically significant improvements in HbA1c (- 0.78%), body weight (- 2.64 kg), and waist circumference (- 3.03 cm) were obtained after 6 months. Reductions were sustained after 12 months in both cohorts (mean semaglutide dose: 0.86 mg in naïve and 0.96 mg in switcher cohort). Blood pressure and lipid profile mean levels decreased after 12 months from semaglutide initiation in both cohorts. No severe hypoglycemia occurred; 6.5% of patients discontinued semaglutide (2.8% due to gastrointestinal side effects). CONCLUSION: Effectiveness and tolerability of semaglutide have been confirmed in the real world irrespective of diabetes duration and severity. As expected, more marked reductions in HbA1c and obesity indices were obtained in naïve patients, but it is noteworthy that relevant improvements were also obtained in patients already treated with GLP-1RAs.

RESUMEN

INTRODUCTION: Real-world evidence on the effectiveness and safety of insulin degludec (IDeg) in patients with diabetes is a priority. We have therefore evaluated the effectiveness and safety of IDeg, including impact on metabolic control, glycemic variability, weight gain and hypoglycemia, in patients with type 1 diabetes under routine clinical practice conditions. METHODS: This was an observational longitudinal multicenter study. A retrospective chart review of all patients with type 1 diabetes who were switched from basal insulin to IDeg was performed, and temporal trends in clinical outcomes were assessed. RESULTS: Data obtained from 195 patients, with a median age of 42.8 [interquartile range (IQR) 24.6-56.4] years and a median diabetes duration of 16 (IQR 10.0-28) years, were analyzed. Median follow-up was 9.5 (IQR 7.7-11.3) months. Improvements were found in glycated hemoglobin (- 0.34%; p < 0.0001), fasting blood glucose (- 24.82 mg/dL; p < 0.0001), post-prandial glucose (- 17.23 mg/dL; p = 0.0009), glycemic variability as indicated by standard deviation of blood glucose (- 5.67 mg/dL; p < 0.0001) and high blood glucose index (- 3.77; p < 0.0001). Body weight and body mass index remained substantially stable during the follow-up (- 0.18 kg; p = 0.56 and - 0.12; p = 0.42, respectively). Risk of nocturnal hypoglycemia decreased by 52% [incidence rate ratio 0.48; 95% confidence interval (CI) 0.29-0.77] and risk of total hypoglycemic episodes by 41% (incidence ratio 0.59; 95% CI 0.45-0.83). Basal and short-acting insulin doses decreased by - 1.4 and - 3.1 IU, respectively. CONCLUSION: Switching patients with type 1 diabetes to IDeg from other basal insulins was associated with relevant improvements in metabolic control and glycemic variability without weight gain; the risk of hypoglycemic episodes also significantly declined. FUNDING: Novo Nordisk S.p.A. unconditional grant.

RESUMEN

Surface expression of a functional B cell antigen receptor (BCR) is essential for the survival and proliferation of mature B cells. Most types of B-cell lymphoproliferative disorders retain surface BCR expression, including B-cell non-Hodgkin lymphomas (B-NHL) and chronic lymphocytic leukemia (CLL). Targeting BCR effectors in B-NHL cell lines in vitro has indicated that this signaling axis is crucial for malignant B cell growth. This has led to the development of inhibitors of BCR signaling, which are currently used for the treatment of CLL and several B-NHL subtypes. Recent studies based on conditional BCR inactivation in a MYC-driven mouse B-cell lymphoma model have revisited the role of the BCR in MYC-expressing tumor B cells. Indeed, lymphoma cells losing BCR expression continue to grow unless subjected to competition with their BCR-expressing counterparts, which causes their elimination. Here, we discuss the molecular nature of the fitness signal delivered by the BCR to MYC-expressing malignant B cells, ensuring their preferential persistence within a rapidly expanding tumor population. We also review growing evidence of Ig-negative cases belonging to several B-NHL subtypes and CLL, and discuss the clinical implications of these findings in relation to an emerging picture of clinical resistances to anti-BCR therapies.

RESUMEN

Hodgkin's lymphoma (HL) is now a highly curable disease, with an improving 5-year survival rate that has now reached 86%. At the time of presentation, HL is usually almost entirely confined to the lymph nodes. We performed a retrospective single-institution study of 384 cases with a median follow-up of 44 months, with the aim of identifying clinical and radiological characteristics and outcomes of patients with bone HL; 32 patients (8%) had primary bone involvement, always with concurrent nodal disease. These included 22 men (69%) and 10 women (31%) with the median age as 41 years. Advanced stages and nodular sclerosis histology prevailed among the subgroup. Radiographic features of bone HL are not specific but indicate a destructive malignant process with osteosclerosis and/or osteolysis. With current chemotherapeutic regimens, the long-term prognosis of patients with osseous HL appears good. The presence of bone lesions in HL should not be interpreted as implying a worse prognosis than without bone involvement.

RESUMEN

INTRODUCTION: Real-world evidence on effectiveness and safety of insulin degludec (IDeg) in patients with diabetes is a priority. The aim of the study was to evaluate patterns of use and the long-term effectiveness and safety of IDeg in routine clinical practice. METHODS: This was an observational longitudinal study. A retrospective chart review of all patients with type 2 diabetes treated with IDeg was performed and temporal trends in clinical outcomes were assessed. All data was stratified by treatment modality: the switch group consisted of patients already treated with another basal insulin before initiating IDeg; the add-on group consisted of basal insulin-naïve patients. RESULTS: Overall, 247 patients were analyzed (55 in the add-on group and 192 in the switch group), mean age 67.0 ± 10.9 years ,and diabetes duration 16.3 ± 8.9 years. Median (interquartile range) follow-up was 9.7 (8.0-11.9) months. In the add-on group, improvements were found in glycated hemoglobin (HbA1c) (- 1.68%; p < 0.0001), fasting blood glucose (FBG) (- 64.7 mg/dL; p < 0.0001), post-prandial glucose (PPG) (- 81.1 mg/dl; p < 0.0001), and glycemic variability (i.e., standard deviation of blood glucose) (- 11.6 mg/dl; p = 0.04). Even in the switch group, improvements were found in HbA1c (- 0.57%; p < 0.0001), FBG (- 28.1 mg/dL; p < 0.0001), and PPG (- 22.6 mg/dl; p = 0.001). Body weight increase during the follow-up was not statistically significant vs. baseline in both groups. Benefits on overall, nocturnal, and severe hypoglycemia were found in the switch group. CONCLUSION: These real-world data documented that initiating IDeg or switching to IDeg from other basal insulins in type 2 diabetes was associated with significant improvement in metabolic control without significant weight gain; a decrease in the risk of hypoglycemia was observed when switching to IDeg from another basal insulin.

RESUMEN

PURPOSE: To identify the characteristics and outcomes of patients with extralymphatic Hodgkin lymphoma. PATIENTS AND METHODS: We performed a retrospective single-institution study of 341 cases comprising 207 male (61%) and 134 female (39%) subjects with a median follow-up of 44 months. RESULTS: Fifty-five patients (16%) had extralymphatic disease. The sites were lung in 29 patients (44%), bone in 22 (33%), liver in 12 (18%), and kidney in 3 (5%). In 46 patients (86%) only one organ was involved, while in 7 patients (13%) extralymphatic disease was present in 2 sites and in 2 patients (3%) in 3 sites. The extralymphatic disease group had a poorer prognosis than the lymphatic disease group. Complete remission rates in the extralymphatic and lymphatic patient subsets were 65% and 82% (P = .043), respectively. CONCLUSION: Extralymphatic disease in patients with Hodgkin lymphoma is a rare occurrence (16%) associated with poor clinical outcome.

RESUMEN

A condition of oxidative stress is known to occur in ischemic stroke, the current therapeutic intervention of which is largely limited to thrombolysis. To assess the effect of vitamin C - in conjunction to aspirin - in ischemic stroke-related lipid peroxidation, we measured plasma levels of ascorbate, of 8,12-isoprostanes F2alpha-VI (8,12-iPF2alpha-VI) and activities and levels of a broad spectrum of antioxidant enzymes and micronutrients in stroke patients randomized to receive, from stroke onset and up to three months, either vitamin C (200 mg/day) plus aspirin (300 mg/day) or only aspirin (300 mg/day). By the end of the first week, patients treated with vitamin C plus aspirin had higher vitamin C levels (p = 0.02) and lower 8,12-iPF2alpha-VI levels (p = 0.01) than patients treated with aspirin alone. The significance was maintained for the increase of vitamin C after three months of therapy (p < 0.01). The clinical functional outcome for both groups of patients similarly ameliorated after three months of treatment. We conclude that vitamin C, at the dose of 200 mg/day and in conjunction with aspirin, significantly decreases ischemic stroke-related lipid peroxidation in humans. Further studies are warranted to clarify whether the use of vitamin C may add clinical long-term beneficial effects in patients with stroke.

RESUMEN

It is well known that type 1 diabetes mellitus (T1DM) is a complex genetic disease resulting from the autoimmune destruction of pancreatic beta cells. Several genes have been associated with susceptibility and/or protection for T1DM, but the disease risk is mostly influenced by genes located in the class II region of the major histocompatibility complex. The attraction of leukocytes to tissues is essential for inflammation and the beginning of autoimmune reaction. The process is controlled by chemokines, which are chemotactic cytolines. Some studies have shown that CCR2-64I and CCR5-Delta 32 might be important for protection of susceptibility to some immunologically-mediated disorders. In the present study, we demonstrate the lack of association between CCR2-64I and CCR5-Delta 32 gene polymorphism and TIDM and we describe a new method for a simple and more precise genotyping of the CCR2 gene.
