A systematic review of dalbavancin efficacy as a sequential therapy for infective endocarditis.

INTRODUCTION: Dalbavancin is an antibiotic characterized by an extended half-life and efficacy against methicillin-resistant Staphylococci. Currently, there are only narrative reviews summarizing the evidence about the use of dalbavancin for infective endocarditis (IE), many of which are focused primarily on its use as consolidation therapy. For this reason, we conducted a systematic review to describe the clinical efficacy and the safety of dalbavancin in IE treatment. METHODS: We searched for available evidence using the MEDLINE (PubMed), Embase, Scopus, Cochrane Library and Web of Science libraries, with no restrictions regarding the publication year. The risk of bias was performed using the Cochrane ROBINS-I tool for the comparative studies and the Newcastle-Ottawa Scale for descriptive studies. RESULTS: Nine studies were included. All of them were observational. Native valve endocarditis was the most common kind of IE found in the studies' populations (128/263, 48.7%), followed by prosthetic valve endocarditis, and cardiovascular implantable electronic device-related endocarditis. Coagulase-negative Staphylococci were the most common pathogens isolated (83/269, 30.1%), followed by S. aureus, Enterococci spp and Streptococci spp. Five out of nine studies documented a clinical failure rate of less than 10%. Dalbavancin showed a favourable safety profile. Dalbavancin appears to be a promising option for the consolidation therapy of IE. However, further studies comparing dalbavancin with standard of care are needed. PROSPERO REGISTRATION NUMBER: CRD42023430032.

Clinical Efficacy and Safety Analysis of Recombinant Human Brain Natriuretic Peptide Combined with Sacubitril/Valsartan in the Sequential Treatment of Senile Patients with Acute Heart Failure.

This study aims to evaluate the comparative efficacy and safety of the combination of recombinant human brain natriuretic peptide (rhBNP) and sacubitril/valsartan in the sequential treatment of senile patients with acute heart failure (AHF).The study objects were a total of 136 senile patients over 60 years old with AHF admitted to the Department of Cardiology of Anji County People's Hospital of Huzhou from August 2022 to August 2023. Using the envelope method, the patients were divided into three groups: the standard treatment group (45 patients who underwent hydragogue, digoxin, valsartan, and beta-blockers), the rhBNP group (46 patients were performed with basic treatment for AHF combined with rhBNP), and the sequential treatment group (45 patients received the basic treatment for AHF combined with rhBNP followed by sacubitril/valsartan). The clinical effects, cardiac function, safety, and prognosis among the three groups were compared.In the sequential treatment group, the duration of clinical symptom remission, the duration of hospitalization, and the improvement rate of New York Heart Association classification at discharge were (2.27 ± 0.76) days, (6.99 ± 1.96) days, and 93.3%, which were better than those in the rhBNP group ([2.58 ± 0.94] days, [7.43 ± 2.78] days, and 78.3%) and the standard treatment group ([2.89 ± 0.71] days, [8.82 ± 2.89] days, and 71.1%); the P value among all groups was lower than 0.05. In terms of cardiac function and myocardial injury, the sequential treatment group was superior to the standard treatment group and rhBNP group. The incidence of adverse reactions in the standard treatment group, the rhBNP group, and the sequential treatment group was 37.8%, 34.8%, and 26.7%, respectively, P = 0.510. In the sequential treatment group, the rate of heart failure readmitted within 6 months after discharge was 28.9% and no death occurred, which was lower than those in the rhBNP (34.8%) and the standard treatment group (35.6%).Sequential treatment with rhBNP and sacubitril/valsartan could significantly improve the clinical symptoms of elderly patients with AHF, enhance cardiac function, and reduce myocardial damage, which could also improve the prognosis.

[Paradigm shift in systemic therapy for metastatic urothelial carcinoma-antibody-drug conjugates (ADCs) and fibroblast growth factor receptor (FGFR) inhibitors]. / Paradigmenwechsel in der Systemtherapie des metastasierten Urothelkarzinoms ­ Antikörper-Wirkstoff-Konjugate (ADC) und FGFR-Inhibitoren ("fibroblast growth factor rezeptor").

BACKGROUND: Patients with locally advanced or metastatic urothelial carcinoma face a poor prognosis. Standard first-line treatment involves platinum-based combinations followed by avelumab maintenance therapy. Follow-up therapies include enfortumab vedotin, vinflunine, and taxanes. OBJECTIVE: To analyze new drug combinations in first-line and follow-up treatment for metastatic urothelial carcinoma concerning their clinical relevance, toxicities, and novel treatment sequences. MATERIALS AND METHODS: Analysis of new study data from EV-302/KN-A39 (enfortumab vedotin and pembrolizumab) and CheckMate-901 (nivolumab and gemcitabine-cisplatin) for untreated metastatic patients as well as TROPHY-U-01 (sacituzumab govitecan) and THOR (erdafitinib) for later lines. RESULTS: The new standard in first-line treatment for metastatic urothelial carcinoma is the combination of enfortumab vedotin and pembrolizumab. For cisplatin-eligible patients with contraindications to enfortumab vedotin, the combination of nivolumab and gemcitabine-cisplatin offers an alternative. Erdafitinib presents a new biomarker-based option in the follow-up treatment of metastatic urothelial carcinoma. CONCLUSION: These novel combinations are revolutionizing the treatment standard for metastatic urothelial carcinoma and necessitate a new approach to managing side effects.

Sono-Triggered Biomimetically Nanoantibiotics Mediate Precise Sequential Therapy of MRSA-Induced Lung Infection.

Bacterial-induced lower respiratory tract infections are a growing global health concern, exacerbated by the inefficacy of conventional antibiotics and delivery methods to effectively target the lower respiratory tract, leading to suboptimal therapeutic outcomes. To address this challenge, this work engineers PBP2a antibody-presenting membrane nanovesicles (AMVs) specifically designed to target the penicillin-binding protein variant on the surface of methicillin-resistant Staphylococcus aureus (MRSA). Concurrently, this work develops pure ciprofloxacin nanoparticles (NanoCip) that, for the first time, exhibits exceptional self-generated sonodynamic properties, attributed to hydrogen-bond-driven self-assembly, while maintaining their inherent pharmacological efficacy. These NanoCip particles are integrated with AMVs to create a novel biomimetic nanomedicine, AMV@NanoCip. This formulation demonstrated remarkable MRSA-targeting affinity in both in vitro and in vivo models, significantly enhancing antibacterial activity. Upon ultrasound stimulation, AMV@NanoCip achieves over 99.99% sterilization of MRSA in vitro, with a reduction exceeding 5.14 Log CFU. Prokaryotic transcriptomic analysis further elucidates the synergistic mechanisms by which AMV@NanoCip, coupled with ultrasound, disrupts the MRSA exoskeleton. In a MRSA-induced pneumonia animal model, AMV@NanoCip+US results in a substantial bacterial load reduction in the lungs (99.99%, 4.02 Log CFU). This sequential treatment strategy (adhesion-membrane disruption-synergistic therapy) offers significant promise as an innovative therapeutic approach for combating bacterial infections.

[Effectiveness of vacuum sealing drainage combined with modified external fixation antibiotic-impregnated cement semi-open technique in treating chronic ulcer wounds].

Objective: To investigate the effectiveness of debridement-vacuum sealing drainage (VSD)-modified external fixation antibiotic-impregnated cement semi-open technique in treatment of chronic ulcer wounds. Methods: Clinical data of 43 patients with chronic ulcer wounds who met the selection criteria and admitted between January 2019 and June 2023 were retrospectively analyzed. Among them, 23 cases were treated with debridement-VSD-modified external fixation antibiotic-impregnated cement semi-open technique (improved group), and 20 cases were treated with debridement-VSD-traditional antibiotic-impregnated cement technique (control group). There was no significant difference in gender, age, constituent ratio of patients with type 2 diabetes mellitus, constituent ratio of patients with smoking history, body mass index, wound site, and other baseline data between the two groups ( P>0.05). The healing quality and healing time, the positive rate of bacterial culture after bone cement coating, the loosening rate of bone cement, the number of operations, the number of hospitalizations, the length of hospitalization, and the cost of hospitalization were recorded and compared between the two groups. Results: Compared with the control group, the positive rate of bacterial culture after bone cement coating and the loosening rate of bone cement in the improved group was significantly lower, as well as the number of operations, the number of hospitalizations, the length of hospitalization, and hospitalization cost significantly reduced ( P<0.05). Wound repair was completed in both groups without amputation. The wound healing quality of the improved group was better than that of the control group and the wound healing time was shorter, the differences were significant ( P<0.05). All patients were followed up 1-5 years (mean 3.4 years), and no ulcers recurred during follow-up. Conclusion: Debridement-VSD-modified external fixation antibiotic-impregnated cement semi-open technique in the treatment of chronic ulcer wounds can effectively reduce the loosening rate of bone cement, facilitate the induced membrane formation and wound healing, and significantly reduce the number of operations and shorten the length of hospital stay.

Chemotherapy Combined With Endocrine Therapy: Old Wine in a New Bottle?

Both chemotherapy (CT) and endocrine therapy (ET) play important roles in the systemic treatment of breast cancer (BC). However, previous studies have shown an antagonistic effect when CT and ET are administered simultaneously. Therefore, sequential administration is more effective than combined administration. The current guidelines and consensus recommend a sequential schedule of CT and ET for patients with hormone receptor-positive (HR+) BC. However, with the continuous introduction of new endocrine drugs, the question of whether the simultaneous administration of CT and ET is superior to sequential therapy has surfaced again as a hot topic of clinical concern. Recent studies have shown that the combination of certain chemotherapeutic agents with endocrine drugs has a synergistic effect. This review aims to summarize the new advances achieved in recent years on the old topic of CT combined with ET in the treatment of BC.

A randomised controlled clinical study of standard triple therapy, bismuth-based quadruple therapy and sequential therapy for Helicobacter pylori infection in children.

BACKGROUND AND AIM: Bismuth and non-bismuth quadruple therapy are the guideline-recommended first-line therapy in children with Helicobacter pylori infection in areas with high antibiotic resistance. However, their efficacy in children is uncertain and there are few well-designed studies. Here, we evaluated the eradication rates of standard triple therapy, bismuth-based quadruple therapy and sequential therapy in children with H. pylori infection. METHODS: A randomised controlled trial was conducted in children infected with H. pylori in West China Second Hospital. They were randomly assigned to 14-day standard triple therapy (omeprazole + amoxicillin + clarithromycin), 14-day bismuth quadruple therapy (bismuth + omeprazole + amoxicillin + clarithromycin) and 10-day sequential therapy (omeprazole + amoxicillin for 5 days followed by omeprazole + clarithromycin + metronidazole for 5 days). The eradication rate was assessed by a 13C-urea breath test 4 to 6 weeks after therapy completion. Symptom improvement and adverse events were compared among the groups. RESULTS: In total, 132 patients were enrolled. The eradication rates of 14-day standard triple therapy, 14-day bismuth quadruple therapy and 10-day sequential therapy were 70.0%, 78.9% and 50.0% in per-protocol analysis and 63.6%, 68.2% and 43.2% in intention-to-treat analysis, respectively. Symptom improvement and adverse drug event rates were similar in the three groups. CONCLUSION: The three therapeutic regimens evaluated in this study are equally not recommendable for H. pylori infection treatment due to unsatisfactory eradication rates. The high prevalence of clarithromycin resistance makes the use of clarithromycin-based quadruple therapy not advisable, even in combination with amoxicillin and bismuth salts.

Efficacy and Safety of Sorafenib or Lenvatinib for Advanced Hepatocellular Carcinoma after Failure of First-Line Atezolizumab Plus Bevacizumab: A Systematic Review and Meta-Analysis.

BACKGROUND: Although atezolizumab plus bevacizumab (hereinafter, atezolizumab-bevacizumab) is the standard first-line treatment for patients with advanced HCC, the optimal second-line regimen remains unknown. This study evaluated the efficacy and safety of sorafenib and lenvatinib in patients with advanced HCC that progressed under atezolizumab-bevacizumab treatment. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched PubMed, Embase, and the Cochrane Library for articles published before November 2023. Random-effects meta-analysis was performed to determine the pooled objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS), comparing patients who received sorafenib versus lenvatinib. RESULTS: Seven studies involving 387 patients were included. The pooled ORR, DCR, OS, and PFS for sorafenib and lenvatinib together were 26% (95% CI: 14-43%), 63% (95% CI: 47-77%), 11.45 months (95% CI: 7.12-15.77, I2 = 92%, p < 0.01), and 3.78 months (95% CI: 2.34-5.23, I2 = 67%, p = 0.02), respectively. Although lenvatinib users had a longer median OS (12.42 vs. 10.75 months) and PFS (5.15 vs. 2.58 months) than sorafenib users, the pooled ORR, DCR, median OS, and PFS for these medications were comparable. Additionally, the distributions of all-grade and grade ≥ 3 adverse events for sorafenib and lenvatinib were comparable to those for these two medications when used as first-line therapies. CONCLUSIONS: Sorafenib or lenvatinib can provide effective treatment with manageable toxicity in patients with advanced HCC after disease progression under atezolizumab-bevacizumab.

Treosulfan-Versus Melphalan-Based Reduced Intensity Conditioning in HLA-Haploidentical Transplantation for Patients ≥ 50 Years with Advanced MDS/AML.

Relapse and regimen-related toxicities remain major challenges in achieving long-term survival, particularly among older patients with high-risk myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). Previous studies have demonstrated the feasibility of treosulfan-based conditioning, noting stable engraftment and low non-relapse mortality (NRM) in patients undergoing HLA-matched allo-HSCT. However, data on treosulfan-based conditioning in the HLA-haploidentical transplantation (HaploT) setting are limited. We retrospectively compared conditioning with fludarabine-cyclophosphamide (FC)-melphalan (110 mg/m2) and FC-treosulfan (30 g/m2) prior to HaploT using post-transplantation cyclophosphamide (PTCy) in patients with high-risk MDS/AML patients ≥ 50 years, transplanted from 2009-2021 at our institution (n = 80). After balancing patient characteristics by a matched-pair analysis, we identified twenty-one matched pairs. Two-year OS and LFS were similar among the groups (OS 66% and LFS 66%, p = 0.8 and p = 0.57). However, FC-melphalan was associated with a significantly lower probability of relapse compared to FC-treosulfan (0% vs. 24%, p = 0.006), counterbalanced by a higher NRM (33% vs. 10%, p = 0.05). Time to engraftment and incidences of acute and chronic graft-versus-host disease (GvHD) did not differ significantly. In conclusion, HaploT using FC-treosulfan in combination with PTCy in patients aged ≥50 years with MDS/AML appears safe and effective, particularly in advanced disease stages. We confirm the favorable extramedullary toxicity profile, allowing for potential dose intensification to enhance antileukemic activity.

Effectiveness of high-dose esomeprazole or pantoprazole 10-day sequential therapy empirically prescribed in Helicobacter pylori-infected naïve patients: a retrospective study.

BACKGROUND AND AIM: Helicobacter pylori infection is one of the most common bacterial infections affecting humans, causing gastroduodenal and extraintestinal diseases. Treatment of the infection remains challenging for the clinicians, and different factors are involved in the failure of the therapeutic approach. The importance of the intensity of acid secretion inhibition remains an unclear issue. The aim of this study is to assess whether 80 mg/day esomeprazole-based 10-day sequential therapy (esomeprazole-ST) achieved different eradication rates when compared to 80 mg/day pantoprazole-based analogous regimen (pantoprazole-ST). METHODS: This was a retrospective observational study where data of consecutive patients referred by their physicians to our unit to perform an upper gastrointestinal endoscopy were analyzed. RESULTS: Overall, 1,327 patients were available for the analysis: 599 and 728 patients received pantoprazole-ST and esomeprazole-ST, respectively. Eradication rate was significantly higher in patients receiving esomeprazole-ST (92.6%, 95% CI: 91-94.5) than pantoprazole-ST (89.3%, 95% CI: 86.7-91.7; difference: 3.3%; 95% CI: 0.2-6.5; P = 0.037). Even after a multivariate analysis, the esomeprazole-ST achieved a significantly higher eradiation (OR: 1.44; 95% CI: 1.1-2.17). CONCLUSIONS: This study showed that esomeprazole-ST achieved significantly higher H. pylori cure rates than pantoprazole-ST. Prospective and well-designed trials are demander to confirm this prelaminar finding.

Lenvatinib radiofrequency ablation sequential therapy offers survival benefits for patients with unresectable hepatocellular carcinoma at intermediate stage and the liver reserve of Child-Pugh A category: A multicenter study.

AIM: This study aims to evaluate the efficacy and safety of lenvatinib radiofrequency ablation (RFA) sequential therapy for certain hepatocellular carcinoma (HCC) patients. METHODS: One hundred and nineteen patients with unresectable HCC in the intermediate stage with Child-Pugh A were retrospectively recruited in a multicenter setting. Those in the lenvatinib RFA sequential therapy group received lenvatinib initially, followed by RFA and the retreatment with lenvatinib. The study compared overall survival (OS), progression-free survival (PFS), tumor response, and adverse events (AEs) between patients undergoing sequential therapy and lenvatinib monotherapy. RESULTS: After propensity score matching, 25 patients on sequential therapy and 50 on monotherapy were evaluated. Independent factors influencing OS were identified as sequential therapy, modified albumin-bilirubin (mALBI) grade, and relative dose intensity (%) with hazard ratios (HRs) of 0.381 (95% confidence interval [CI], 0.186-0.782), 2.220 (95% CI, 1.410-3.493), and 0.982 (95% CI, 0.966-0.999), respectively. Stratified analysis based on mALBI grades confirmed the independent influence of treatment strategy across all mALBI grades for OS (HR, 0.376; 95% CI, 0.176-0.804). Furthermore, sequential therapy was identified as an independent factor of PFS (HR, 0.382; 95% CI, 0.215-0.678). Sequential therapy significantly outperformed monotherapy on survival benefits (OS: 38.27 vs. 18.96 months for sequential therapy and monotherapy, respectively, p = 0.004; PFS: 13.80 vs. 5.32 months for sequential therapy and monotherapy, respectively, p < 0.001). Sequential therapy was significantly associated with complete response by modified Response Evaluation Criteria in Solid Tumors (odds ratio, 63.089). Ten of 119 patients experienced grade 3 AEs, with no AE beyond grade 3 observed. CONCLUSION: Lenvatinib RFA sequential therapy might offer favorable tolerability and potential prognostic improvement compared to lenvatinib monotherapy.

Dalbavancin as sequential therapy in infective endocarditis: Real-life experience in elder and comorbid patients.

OBJECTIVES: This study aimed to evaluate the effectiveness of dalbavancin as sequential therapy in patients with infective endocarditis (IE) due to gram positive bacteria (GPB) in a real-life heterogenous cohort with comorbid patients. METHODS: A single center retrospective cohort study including all patients with definite IE treated with dalbavancin between January 2017 and February 2022 was developed. A 6-month follow-up was performed. The main outcomes were clinical cure rate, clinical and microbiological relapse, 6-month mortality, and adverse effects (AEs) rate. RESULTS: The study included 61 IE episodes. The median age was 78.5 years (interquartile range [IQR] 63.2-85.2), 78.7% were male, with a median Charlson comorbidity index of 7 (IQR 4-9) points. Overall, 49.2% suffered native valve IE. The most common microorganism was Staphylococcus aureus (26.3%) followed by Enterococcus faecalis (21.3%). The median duration of initial antimicrobial therapy and dalbavancin therapy were 27 (IQR 20-34) and 14 days (IQR 14-28) respectively. The total reduction of hospitalization was 1090 days. The most frequent dosage was 1500mg of dalbavancin every 14 days (96.7%). An AE was detected in 8.2% of patients, only one (1.6%) was attributed to dalbavancin (infusion reaction). Clinical cure was achieved in 86.9% of patients. One patient (1.6%) with Enterococcus faecalis IE suffered relapse. The 6-month mortality was 11.5%, with only one IE-related death (1.6%). CONCLUSION: This study shows a high efficacy of dalbavancin in a heterogeneous real-world cohort of IE patients, with an excellent safety profile. Dalbavancin allowed a substantial reduction of in-hospital length of stay.

Dual-Polymer Functionalized Melanin-AgNPs Nanocomposite with Hydroxyapatite Binding Ability to Penetrate and Retain in Biofilm Sequentially Treating Periodontitis.

Periodontitis is the leading cause of adult tooth missing. Thorny bacterial biofilm and high reactive oxygen species (ROS) levels in tissue are key elements for the periodontitis process. It is meaningful to develop an advanced therapeutic system with sequential antibacterial/ antioxidant ability to meet the overall goals of periodontitis therapy. Herein, a dual-polymer functionalized melanin-AgNPs (P/D-MNP-Ag) with biofilm penetration, hydroxyapatite binding, and sequentially treatment ability are fabricated. Polymer enriched with 2-(Dimethylamino)ethyl methacrylate (D), can be protonated in an acid environment with enhanced positive charge, promoting penetration in biofilm. The other polymer is rich in phosphate group (P) and can chelate Ca2+, promoting the polymer to adhere to the hydroxyapatite surface. Melanin has good ROS scavenging and photothermal abilities, after in situ reduction Ag, melanin-AgNPs composite has sequentially transitioned between antibacterial and antioxidative ability due to heat and acid accelerated Ag+ release. The released Ag+ and heat have synergistic antibacterial effects for bacterial killing. With Ag+ consumption, the antioxidant ability of MNP recovers to scavenge ROS in the inflammatory area. When applied in the periodontitis model, P/D-MNP-Ag has good therapeutical effects to ablate biofilm, relieve inflammation state, and reduce alveolar bone loss. P/D-MNP-Ag with sequential treatment ability provides a reference for developing advanced oral biofilm eradication systems.

Comparison of Cabozantinib and Axitinib as Second-line Therapy After Nivolumab Plus Ipilimumab in Patients With Metastatic Clear Cell Renal Cell Carcinoma: A Comparative Analysis of Retrospective Real-world Data.

BACKGROUND: To date, no studies have compared the treatment outcomes of second-line therapies in patients with metastatic clear cell renal cell carcinoma (ccRCC). This study retrospectively evaluated the efficacy of cabozantinib and axitinib as second-line treatments in patients with metastatic ccRCC who previously received immune-oncology combination therapy. PATIENTS AND METHODS: Patients with metastatic ccRCC treated with cabozantinib and axitinib as second-line therapy after nivolumab-ipilimumab treatment were identified among 243 patients with RCC treated between August 1, 2018 and January 31, 2022 at 34 institutions belonging to the Japanese Urological Oncology Group. Patients were assessed for treatment outcomes, including progression-free survival (PFS), overall survival, objective response rate (ORR), and incidence rate of treatment-related adverse events (AEs). RESULTS: Forty-eight patients treated with cabozantinib and 60 treated with axitinib as second-line therapy after nivolumab-ipilimumab treatment for metastatic ccRCC were identified. The median PFS (95% confidence interval) was 11.0 months (9.0-16.0) with cabozantinib and 9.5 months (6.0-13.0) with axitinib. The ORRs were 37.5% (cabozantinib) and 38.3% (axitinib). The rates of any-grade AEs and grade ≥3 AEs were 79.2% (cabozantinib) versus 63.3% (axitinib; P = .091) and 35.4% (cabozantinib) versus 23.3% (axitinib; P = .202), respectively. In the poor-risk group, PFS was longer in the cabozantinib group than in the axitinib group (P = .033). CONCLUSION: The efficacy and safety of cabozantinib and axitinib were comparable. In the poor-risk group, cabozantinib was more effective than axitinib. These findings provide valuable insights into the selection of second-line treatment options after nivolumab-ipilimumab treatment in patients with metastatic ccRCC.

Pre-first-line chemotherapy risk stratification for overall survival in advanced urothelial carcinoma in sequential therapy era.

PURPOSE: To explore pre-treatment risk factors for overall survival (OS) in advanced urothelial carcinoma (UC) patients treated with first-line (1L) chemotherapy in sequential therapy (ST) era. Additionally, to evaluate the proportion of patients who were not able to undergo subsequent immune checkpoint inhibitor (ICI) therapy according to the subgroups stratified by the risk factors. METHODS: A multicenter retrospective study was conducted. Metastatic or locally advanced UC patients treated between 2017 and 2022 were included. The Kaplan-Meier method with the log-rank test and multivariate Cox regression models were used to address OS. RESULTS: Three hundred and fourteen patients treated with 1L chemotherapy were included in the study and 57 (18.2%) patients were not able to proceed to subsequent ICI therapy. Pre-chemotherapy risk factors for OS in 314 patients were ECOG-PS 1 or more, having no primary site resection, C-reactive protein (CRP) level of 3 mg/dL or more, and non-cisplatin-based regimen. Patients having 3 or 4 risk factors had higher risk for not being able to receive ST (Mann-Whitney U test, P < 0.001). As risk factors for OS in 230 patients who were able to receive ST, having no primary site resection, a neutrophil to lymphocyte ratio of 3 or more, and the presence of liver metastasis were identified. CONCLUSION: We reported the risk factors for OS in advanced UC patients treated with 1L chemotherapy in ST era. Patients with high risk for OS may not be able to proceed to subsequent ICI therapy even in the ST era.

Real-world patterns and sequences of targeted therapy use in chronic lymphocytic leukemia and small lymphocytic lymphoma in the United States: a longitudinal study.

With increasing focus on novel targeted therapies for chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), this longitudinal claims-based study evaluated real-world CLL/SLL treatment sequences, particularly sequential targeted therapy. Among patients with first-line (1 L) treatment in 2014-2017 (N = 2,612; median follow-up = 3 years), the most common 1 L treatment was chemoimmunotherapy (CIT; 44.6%), followed by CD20 (25.2%) and Bruton's tyrosine kinase inhibitors (BTKi; 21.7%). Among those with 1 L in 2018-2021 (N = 4,534; median follow-up = 1 year), these were BTKi (45.5%), CD20 (20.4%), CIT (17.5%), and B-cell lymphoma 2 inhibitor (8.3%). In 2014-2017, the proportion of patients receiving sequential targeted therapy in the first 2 LOTs was 11.2% (80.2% was BTKi→BTKi); in 2018-2021, this proportion was 34.3% (66.4% was BTKi→BTKi). Over time, there was a substantial increase in targeted therapy use in 1 L and sequential targeted therapy, particularly with BTKi→BTKi. Future studies should assess clinical outcomes to determine optimal sequences for CLL/SLL and reasons for restarting BTKi.

Allogeneic Stem Cell Transplantation in Refractory Acute Myeloid Leukaemia.

Refractory acute myeloid leukaemia is very difficult to treat and represents an unmet clinical need. In recent years, new drugs and combinations of drugs have been tested in this category, with encouraging results. However, all treated patients relapsed and died from the disease. The only curative option is allogeneic transplantation through a graft from a healthy donor immune system. Using myeloablative conditioning regimens, the median overall survival regimens is 19%. Several so-called sequential induction chemotherapies followed by allogeneic transplantation conditioned by reduced intensity regimens have been developed, improving the overall survival to 25-57%. In the allogeneic transplantation field, continuous improvements in practices, particularly regarding graft versus host disease prevention, infection prevention, and treatment, have allowed us to observe improvements in survival rates. This is true mainly for patients in complete remission before transplantation and less so for refractory patients. However, full myeloablative regimens are toxic and carry a high risk of treatment-related mortality. In this review, we describe the results obtained with the different modalities used in more recent retrospective and prospective studies. Based on these findings, we speculate how allogeneic stem cell transplantation could be modified to maximise its therapeutic effect on refractory acute myeloid leukaemia.

Asia-Pacific consensus on long-term and sequential therapy for osteoporosis.

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition. The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and antiresorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to antiresorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for individuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions: This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.

Zoledronate After Denosumab Discontinuation: Is Repeated Administrations More Effective Than Single Infusion?

BACKGROUND: After denosumab (Dmab) discontinuation C-terminal telopeptide (CTX) levels increase, bone mineral density (BMD) decreases and multiple vertebral fractures (FX) may occur with relevant impacts on women's health. A sequential therapy with bisphosphonates is recommended, and the European Calcified Tissue Society (ECTS) proposed repeated zoledronate (ZOL) administrations in patients with persistently high CTX levels, although the efficacy of this schedule is unknown. In this retrospective study, we describe BMD changes and FX rate in 52 patients managed according to the ECTS recommendations. METHODS: We measured CTX levels and administered ZOL after 1 month from Dmab withdrawal (t0). After 6 months (t1), we administered a second ZOL infusion, if CTX levels were ≥280 ng/L. BMD changes and FX rate were assessed on average after 17 months from Dmab withdrawal. RESULTS: Seventy-five percent of patients repeated ZOL infusion. In this group, spine BMD declined significantly (-5.5 ± 5.6%), while it remained stable in the group with CTX levels <280 ng/L (-0.1 ± 5.5%, P = 0.008). All fractured patients (9.6%) had received >5 Dmab injections and 2 ZOL infusions. The BMD worsening after Dmab withdrawal was associated with CTX t1 [odds ratio (OR) 2.9, interquartile range (IQR) 1.3-6.6, P = .009] and spine BMD gain during Dmab therapy corrected for the number of Dmab injections (OR 3.0, IQR 1.2-7.2, P = .014). A CTX level at t1 > 212 ng/L had 100% sensitivity in predicting the BMD loss. CONCLUSION: In patients with uncontrolled CTX levels after Dmab withdrawal, 2 ZOL infusions 6 months apart do not prevent BMD loss and FX.
