A Case of Relapse Pseudomonas aeruginosa Tricuspid Valve Endocarditis After AngioVac Vegectomy and Antibiotic Treatment in a Patient Using Intravenous Drugs.

Infective endocarditis (IE) is a bloodstream infection affecting the valves of the heart. IE is highly associated with morbidity and mortality if not properly managed. Pseudomonas aeruginosa (P. aeruginosa) as a cause of IE is extremely rare. This is a case of IE involving a male patient with a history of intravenous drug use (IVDU), secondary to P. aeruginosa, with associated relapse of bacteremia and native tricuspid valve endocarditis, complicated by septic pulmonary emboli, despite undergoing recent vegetation debulking using the AngioVac system (AngioDynamics, Inc., New York, USA) along with six weeks of IV antibiotics and no IVDU since then being on treatment.

Comparison of hematopoietic stem cell transplantation and repeated intensified immunosuppressive therapy as second-line treatment for relapsed/refractory severe aplastic anemia.

The optimal treatment for patients with severe aplastic anemia (SAA) who fail an initial course of antithymocyte globulin (ATG) plus cyclosporine has not yet been established. We compared the effectiveness of allogeneic hematopoietic stem cell transplantation (allo-HSCT) (n = 36) with repeated immunosuppressive therapy (IST) (n = 33) for relapsed/refractory SAA between 2007 and 2022. In the IST group, patients were retreated with ATG (n = 16) or high-dose cyclophosphamide (n = 17). The overall response rate was 57.6% at 6 months and 60.6% at 12 months. In the allo-HSCT group, patients received a transplant from a matched sibling donor (n = 6), matched unrelated donor (n = 7), or haploidentical donor (n = 23). All patients achieved neutrophil engraftment, and there were no cases of primary graft failure. The cumulative incidences (CIs) of grades II-IV and III-IV acute graft-versus-host disease (GVHD) were 36.1% ± 0.7% and 13.9% ± 0.3% at day +100, respectively. The 4-year CI of chronic GVHD (cGVHD) was 36.2% ± 0.7%, with moderate to severe cGVHD at 14.9% ± 0.4%. Compared with IST, HSCT recipients showed much higher hematologic recovery rate at 3, 6, and 12 months (63.9%, 83.3%, and 86.1%, respectively, p < 0.001). The estimated 4-year overall survival (OS) (79.8% ± 6.8% vs. 80.0% ± 7.3%, p = 0.957) was similar; however, the failure-free survival (FFS) was significantly better in the HSCT group (79.8% ± 6.8% vs. 56.6% ± 8.8%, p = 0.049). Of note, children in the HSCT cohort were all alive without treatment failures, exhibiting superior OS (100% vs. 50.0% ± 17.7%, p = 0.004) and FFS (100% vs. 50.0% ± 17.7%, p = 0.004) than children in the IST cohort. Subgroup analysis revealed that younger patients (age ≤ 35 years), especially children, and those with refractory SAA benefited more from HSCT. Therefore, for these patients, salvage HSCT may be more preferable than a second course of IST.

Relapse-Independent disease activity in neuromyelitis optica spectrum disorder: A systematic review.

INTRODUCTION: Neuromyelitis Optica Spectrum Disorders (NMOSD) is a neuroinflammatory condition characterized by optic neuritis and transverse myelitis. While the current approach to NMOSD focuses on relapse-associated worsening (RAW), recent evidence indicates Relapse-Independent Disease Activity (RIDA) in patients. METHOD: Databases including Embase, PubMed, Scopus, and Web of Sciences were systematically searched up to December 2023. No restrictions were applied. Inclusion criteria focused on studies reporting evidence of RIDA in NMOSD patients. Data extraction involved details such as study title, author, participant characteristics, treatment, evaluation methods, positive findings according to RIDA, and prevalence of findings in NMOSD patients. This study is conducted following the PRISMA guidelines with a registered protocol on PROSPERO (ID = CRD42023492352). RESULT: Of 802 studies, 38 were included in the systematic review, covering 1881 NMOSD patients. AQP4-IGg status was positive in 90.6 % of the patients. Ocular findings indicative of RIDA were reported in 23 studies, including thinning of GCIPL, RNFL, GCC, and GCL layers, foveal and macular shape and volume abnormalities, vessel loss, and visual evoked potentials (VEPs) abnormalities. MRI findings supporting the RIDA were reported in 13 studies, including new lesion incidence and brain and spinal cord atrophy. Serum and CSF RIDA-supporting findings were reported in five studies, including elevation in sGFAP and sNFL. Biopsies and autopsies suggested inflammatory processes in relapse-free patients in 2 studies. The predominant manifestation of RIDA in NMOSD was identified in the visual system, suggesting the impaired retinal glial cells like Müller cells during the relapse-free period in NMOSD. INTERPRETATION: Our systematic review provides valuable insights into RIDA in NMOSD. Establishing guidelines for the diagnosis and treatment of RIDA is crucial. Further studies are needed to provide robust evidence on RIDA in NMOSD patients.

Timing of relapse as a key indicator of steroid-sparing requirements in childhood idiopathic nephrotic syndrome.

BACKGROUND: Managing children with frequent relapses or steroid-dependent nephrotic syndrome poses challenges due to recurrent relapses necessitating prolonged steroid exposure, thus increasing susceptibility to long-term complications. Identifying those at risk of poor response to steroid therapy may be helpful to guide timely intervention with steroid-sparing agents. This study aimed to identify factors associated with steroid-sparing agent needs in children with frequent relapses or steroid-dependent nephrotic syndrome. METHODS: A retrospective multicenter cohort study was conducted by reviewing the medical records of children with idiopathic nephrotic syndrome treated between 2006 and 2023. Cox proportional regression analyzed prognostic factors for steroid-sparing agent requirements in children with frequent relapses or steroid-dependent nephrotic syndrome. The time-to-event analysis utilizing the Kaplan-Meier estimate examined the proportion of children needing steroid-sparing agents after diagnosis. RESULTS: Medical records of 121 children (85 males) diagnosed with idiopathic nephrotic syndrome at a median age of 4.5 years (range 1.3-12.8) were reviewed over a median follow-up of 3.7 years (range 1.0-15.0). Time to subsequent relapse post-frequent relapses or steroid-dependent nephrotic syndrome diagnosis (at 3-month threshold) emerged as the sole significant predictor of steroid-sparing agent requirement, adjusted hazard ratio (aHR) = 2.26, 95% confidence interval (CI) 1.26-4.05. Kaplan-Meier analysis indicated that an earlier first relapse (< 3 months) led to earlier steroid-sparing agent requirement (log-rank p = 0.005). Children who relapsed within 3 months post-frequent relapses or steroid-dependent nephrotic syndrome diagnosis exhibited a higher frequency of relapses, a greater incidence of steroid-related adverse events, and were more likely to develop steroid dependency. CONCLUSIONS: Early subsequent relapse following diagnosis of frequent relapses or steroid-dependent nephrotic syndrome was linked to earlier requirement of steroid-sparing agent therapy. Further prospective research is necessary to confirm this observation.

Fasting insulinemia as biomarker of illness relapse in patients with severe mental illness?

Severe Mental Illness (SMI) is often associated with metabolic alteration and/or metabolic syndrome, which may determine an increased mortality due to a further increased cardiovascular risk. The relationship with metabolic syndrome is often bidirectional, resulting in a pathoplastic effect of these dysmetabolisms. Among the several hormones involved, insulin appears to play a key role, albeit not entirely clear. The aim of our real-world cross-sectional observational study is to investigate a set of metabolic biomarkers of illness relapse/recurrence/onset in a cohort of 310 adult SMI inpatients consecutively admitted to the Psychiatry Clinic of the Azienda Ospedaliero Universitaria of Marche, in Ancona (Italy), between February 2021 and February 2024. According to the stepwise multivariate regression model, a higher number of acute episodes per year was positively predicted by the age of illness onset, the lifetime number of suicidal attempts and fasting insulinemia and negatively by the participant's age. A second stepwise multivariate regression model using only the metabolic characteristics as independent variables, found that a higher number of acute episodes per year was predicted positively by the fasting insulinemia and red blood cells and negatively by the abdominal circumference. Overall, our findings could provide practical implications for the treatment and management of SMI patients, emphasizing the importance of monitoring and managing metabolic factors, particularly insulinemia, metabolic syndrome and insulin resistance. Finally, insulinemia could potentially act as metabolic biomarker of illness relapse, though more larger and longitudinal studies should be carried out to confirm these results.

Prognostic significance of paramagnetic rim lesions in multiple sclerosis: A systematic review.

The diagnostic potential of paramagnetic rim lesions (PRLs) has been previously established; however, the prognostic significance of these lesions has not previously been consistently described. This study aimed to establish the prognostic role of PRLs in MS with respect to the Expanded Disability Status Scale (EDSS) and rates of disability progression. Databases of PubMed, EMBASE, Scopus and reference lists of selected articles were searched up to 29/04/2023. The review was conducted in accordance with PRISMA guidelines and was registered prospectively on PROSPERO (CRD42023422052). 7 studies were included in the final review. All of the eligible studies found that patients with PRLs tend to have higher baseline EDSS scores. Longitudinal assessments revealed greater EDSS progression in patients with PRLs over time in most studies. However, the effect of location of PRLs within the central nervous system were not assessed across the studies. Only one study investigated progression independent of relapse activity (PIRA) and showed that this clinical entity occurred in a greater proportion in patients with PRLs. This review supports PRLs as a predictor of EDSS progression. This measure has widespread applicability, however further multicentre studies are needed. Future research should explore the impact of PRLs on silent disability, PIRA, take into account different MS phenotypes and the topography of PRLs in prognosis.

Tumor-derived Immunoglobulin-like transcript 4 promotes postoperative relapse via inducing vasculogenic mimicry through MAPK/ERK signaling in hepatocellular carcinoma.

Traditional anti-angiogenesis drugs are usually unsatisfactory in hepatocellular carcinoma (HCC) treatment. Therefore, it is urgent to find new precise therapeutic targets and further develop more effective drugs for the treatment of HCC. Vasculogenic mimicry (VM) is different from classical endothelium-dependent angiogenesis and associated with poor prognosis in patients with malignant tumor. However, the mechanism underlying VM occurrence is complex and not fully defined. Immunoglobulin-like transcript (ILT) 4, as a negative regulator of immune response, was recently found expressed in many solid tumors. However, whether and how ILT4 regulate VM remains unclear. In this study, we found VM enriched in HCC tissues especially in tissues from patients who experience relapse within 5 years after surgery. Similarly, ILT4 expression level was also higher in HCC tissues from patients who experience relapse within 5 years after surgery. Linear regression analysis revealed a positive correlation between the expression of ILT4 and VM density. Further, Overexpression/knockdown of ILT4 expression upregulated/downregulated VM related marker, three-dimensional tube formation, the migration and invasion of HCC cell lines in vitro. Mechanistic studies showed that ILT4 promoted VM formation via MAPK/ERK signaling. In conclusion, this study provides a rationale and mechanism for ILT4-mediated postoperative relapse via inducing VM in HCC. The related molecular pathways can be used as novel therapeutic targets for the inhibition of HCC angiogenesis and postoperative relapse.

The Association Between Surgical Site Infection and Prognosis of T4 Colorectal Cancer.

OBJECTIVES: Patients with T4 colorectal cancer have poor prognosis, wherein no prognostic factors have been established. Surgical site infection (SSI) has been reported to be one of the risk factors for colorectal cancer recurrence. In this study, we evaluated the relationship between SSI occurrence and prognosis of T4 colorectal cancer and the prognostic impact of the site of SSI occurrence. METHODS: We examined 100 patients with T4 colorectal cancer who underwent radical surgery between April 2002 and December 2017, in a retrospective case-control study, excluding stage IV cases, and classified them into two groups: without SSI (non-SSI) and with SSI (SSI). The five-year relapse-free survival (RFS) and overall survival (OS) were calculated and compared between the two groups. The relationship between prognosis and the SSI site was also assessed according to the SSI site in the incisional/deep and organ/space SSI groups.  Results: The without SSI and with SSI groups included 73 and 27 patients, respectively. The five-year RFS was 55.1% and 22.2% in the without SSI and with SSI groups, respectively (hazard ratio (HR), 2.224; 95% confidence interval (CI), 1.269-3.898; P=0.005). The five-year OS was 67.0% and 38.4% in the without SSI and with SSI groups, respectively (HR, 2.366; 95% CI, 1.223-4.575; P=0.010). The patients in the with SSI group had a significantly poorer prognosis compared with the without SSI group. By SSI site, the prognosis was significantly worse in patients with SSI in the incisional/deep SSI group. CONCLUSIONS: In T4 colorectal cancer, SSI occurrence was a high-risk factor for recurrence and may be a prognostic factor. This result suggested that patients with SSI occurrence may require close postoperative follow-up and appropriate adjuvant chemotherapy.

Efficacy and safety of daratumumab in multiresistant immune-mediated thrombotic thrombocytopenic purpura.

The immunosuppressive treatment of immune-mediated thrombotic thrombocytopenic purpura (iTTP) in patients with intolerance or refractoriness to the B-cell depleting monoclonal antibody rituximab remains debated. Daratumumab, a plasma cell-directed monoclonal antibody targeting CD38, represents a therapeutic option, but data are scarce. The French Thrombotic Microangiopathies Reference Center conducted a nationwide survey on iTTP patients treated with daratumumab. Nine episodes from seven patients were identified. Treatment was administered for A Disintegrin And Metalloproteinase with ThromboSpondin-1 motifs, 13th member (ADAMTS13) relapses while patients were otherwise in clinical response (N = 8), or during the acute phase of the disease following rituximab intolerance (N = 1). Patients have received a median of three previous therapeutic lines. ADAMTS13 activity improved in eight cases following daratumumab administration, including three cases where ADAMTS13 normalized. ADAMTS13 relapses occurred in three patients; in two cases, retreatment with daratumumab was successful. Median ADAMTS13 relapse-free survival was not reached; 12-month ADAMTS13 relapse-free survival was 56%. Daratumumab-related adverse events occurred in five cases and were non-severe infusion-related reactions in all cases. These results suggest that daratumumab may be an effective treatment option for iTTP patients with intolerance or refractoriness to rituximab.

Anti-PD-1 combined with hypomethylating agent and CAG regimen bridging to allogeneic hematopoietic stem cell transplantation: a novel strategy for relapsed/refractory acute myeloid leukemia.

Introduction: The prognosis of relapsed/refractory acute myeloid leukemia (r/rAML) is dismal, and allogeneic hematopoietic stem cell transplant (allo-HSCT) is a potential cure. Combining anti-PD-1, hypomethylating agent (HMA), and CAG (cytarabine, aclarubicin/idarubicin, granulocyte colony-stimulating factor) regimen has showed primary efficacy in r/rAML. However, pre-transplant exposure to anti-PD-1 may lead to severe graft-versus-host disease (GVHD). This preliminary study aimed to evaluate the safety and efficacy of allo-HSCT in r/rAML patients receiving the anti-PD-1+HMA+CAG regimen. Methods: Fifteen r/rAML patients (12 related haploidentical donors [HIDs], 2 matched siblings, 1 unrelated donor) received this regimen and subsequent peripheral blood HSCT. Results: Four patients with HIDs received a GVHD prophylaxis regimen consisted of Anti-thymocyte globulin and a reduced-dose of post-transplant cyclophosphamide. The median follow-up was 20.9 months (range, 1.2-34.2). The cumulative incidences of acute GVHD grade 2-4 and grade 3-4 were 40% and 13.3%, respectively. The 2-year incidence of moderate-to-severe chronic GVHD, non-relapse mortality, and relapse were 10%, 22.3%, and 22.5%, respectively. The 2-year overall survival and GVHD-free/relapse-free survival rates were 54% and 48.6%, respectively. No death or relapse was observed in the PTCy group. Conclusion: The anti-PD-1+HMA+CAG regimen bridging to allo-HSCT for r/r AML was tolerable with promising efficacy. GVHD prophylaxis with PTCy for HID-HSCT showed preliminary survival advantage.

Description and Prognosis of Patients with Recovered Dilated Cardiomyopathy: A Retrospective Cohort Study.

Background: With the recent advances in the treatment of heart failure (HF), it is intriguing that a very small number of patients with dilated cardiomyopathy (DCM) have been observed as being fully recovered. However, knowledge of the progression and prognosis of patients with recovered DCM remains sparse. Herein, we conducted this study to investigate the clinical characteristics and prognosis of patients with recovered DCM. Methods: Consecutive patients with recovered DCM referred to our hospital between March 2009 and May 2021 were included. The recovered DCM patients were categorized into relapse and non-relapse groups. The primary endpoint was all-cause death, and the secondary endpoint was HF re-hospitalization during follow-up. Multivariate analyses were performed to identify predictors of relapse among recovered DCM patients. Kaplan-Meier analyses were used to assess the prognostic significance of relapse. Results: A comparatively large cohort of 122 recovered DCM patients from 10,029 DCM patients was analyzed. During a median follow-up duration of 53.5 months, the relapse rate among recovered DCM patients was 15.6% (19/122). Age (odds ratio, OR 1.079, 95% confidence interval, CI: 1.014-1.148; p = 0.017), systolic blood pressure (SBP) at diagnosis (OR 0.948, 95% CI: 0.908-0.990; p = 0.015) and changes in left ventricular ejection fraction from diagnosis to recovery ( Δ LVEF) (OR 0.898, 95% CI: 0.825-0.978; p = 0.013) were identified as predictors of relapse. Furthermore, among 122 patients, 5 (4.1%) experienced death, and 12 (9.8%) underwent HF re-hospitalization. Four deaths occurred in the relapse group, with one in the non-relapse group. All deaths were attributed to cardiovascular events. The long-term prognosis of the relapse group was significantly worse compared to the non-relapse group by Kaplan-Meier analysis (p < 0.001 based on the log-rank test). Multivariate analyses significantly associated relapse with all-cause mortality in recovered DCM patients (hazard ratio, HR 7.738, 95% CI: 1.892-31.636; p = 0.004). Conclusions: Recovered DCM patients are at risk of relapse. Older age, lower SBP, and smaller Δ LVEF were independently associated with relapse in recovered DCM patients. Relapse after recovery was related to an unfavorable long-term prognosis.

Outcomes of older adults undergoing allogeneic hematopoietic cell transplantation with post-transplant cyclophosphamide based prophylaxis.

This study evaluates the feasibility of using post-transplant cyclophosphamide (PTCY) prophylaxis in allo-hematopoietic cell transplantation (HCT) for adults aged 65 and older. PTCY is increasingly used to prevent graft-versus-host disease (GVHD) across all donor types, but concerns remain about potential risks, especially in older patients. Fifty-seven adults aged 65 or older with hematological malignancies, undergoing their first allo-HCT with PTCY prophylaxis between January 2011 and January 2023 were included. Overall, 94.8% of patients achieved primary engraftment. The median durations for neutrophil and platelet engraftments were 19 and 21 days. The day +30 cumulative incidence of bacterial bloodstream infection was 43.9%. No CMV reactivations occurred within the first 100 days after letermovir implementation. The day +180 cumulative incidences of grade II-IV and III-IV acute GVHD, and the 2-year cumulative incidence of moderate/severe chronic GVHD were 26.3%, 10.5%, and 4.8%. Eighteen patients (31.6%) relapsed, and 30 (52.6%) died, with relapse (16.4%) and infection (11.5%) being the main causes of death. The estimated 2-year overall survival, non-relapse mortality, cumulative incidence of relapse, and GVHD-free relapse-free survival rates were 45.5%, 27.1%, 33.9%, and 37.0%. Adults aged 70 or older had similar outcomes to those aged 65-69. This study confirms the safety and feasibility of PTCY-based allo-HCT in older adults.

Vascular ultrasound as a follow-up tool in patients with giant cell arteritis: a prospective observational cohort study.

Objectives: To evaluate relapses in giant cell arteritis (GCA), investigate the utility of vascular ultrasound to detect relapses, and develop and assess a composite score for GCA disease activity (GCAS) based on clinical symptoms, ultrasound imaging activity, and C-reactive protein (CRP). Methods: Patients with GCA were prospectively followed with scheduled visits, including assessment for clinical relapse, protocol ultrasound examination, and CRP. At each visit, patients were defined as having ultrasound remission or relapse. GCAS was calculated at every visit. Results: The study included 132 patients, with a median follow-up time of 25 months [interquartile range (IR) 21]. The clinical relapse rate was 60.6%. There were no differences in relapse rates between GCA subtypes (cranial-GCA, large vessel (LV)-GCA, and mixed-GCA) (p = 0.83). Ultrasound yielded a sensitivity of 61.2% and a specificity of 72.3% for diagnosing GCA- relapse in our cohort. In 7.7% of follow-up visits with clinical relapses, neither high CRP nor findings of ultrasound relapse were registered. In comparison, in 10.3% of follow-up visits without symptoms of clinical relapse, there were both a high CRP and findings of ultrasound relapse. Conclusion: We found moderate sensitivity and specificity for ultrasound as a monitoring tool for relapse in this prospective cohort of GCA patients. The extent or subtype of vasculitis at the diagnosis did not influence the number of relapses. Based on a combination of clinical symptoms, elevated CRP, and ultrasound findings, a composite score for GCA activity is proposed.

Prognosis and Factors 4 to 10 Years After Deep Vein Thrombosis: A Long-Term Follow-up Cohort Study.

Post-thrombotic syndrome (PTS) is one of the most common long-term complications of lower extremity deep vein thrombosis (DVT). In order to study the long-term adverse prognosis of patients with DVT, explore the influencing factors for the prognosis of DVT, and provide a reliable reference for future research in the field of venous thrombosis, we collected and summarized information about the incidence of PTS, the PTS score and grading, the associated symptoms and drug-related adverse reactions in 501 patients with DVT. In our study, 54.1% of patients with DVT (271 of 501) experienced indications and manifestations of PTS, the male to female ratio was approximately 1:1. During the long-term follow up, the most common symptoms of PTS were anterior tibial edema and pain. By statistical analysis, we found that the outcome of thrombosis was the influencing factor of PTS score (1-4 points, P<.05). The grading of PTS was primarily influenced by the history of varicose veins and DVT in the lower extremities. The duration of taking antithrombotic drugs affected the outcome of thrombosis (P<.05), especially among the female patients. In addition, varied factors, such as lower extremity DVT complicated with pulmonary embolism and the duration of antithrombotic drug use were found to increase the chances of experiencing drug-related adverse reactions (odds ratio [OR]=2.798, 95% confidence interval [CI]: 1.413-5.541 / OR=2.778, 95% CI: 1.231-6.269). The above 2 factors were significant only among female patients with DVT (OR=4.03, 95% CI: 1.608-10.103 / OR=3.918, 95% CI: 1.123-13.669).

Anatomical requirements for dacryocystorhinostomy ostium patency.

PURPOSE: To identify anatomical factors affecting the outcome of dcryocystorhinostomy (DCR). METHODS: The study included the results of dacryocystography in 73 patients after DCR: 37 cases of failed DCR and 36 cases of successful DCR. Biometric characteristics of the formed ostium were evaluated: the horizontal size of the bony "window" and the soft tissue part of the ostium, the vertical size of the bony "window" and soft tissue ostium, the height of the fragment of the remaining bone above and below the line of the common canaliculus, and the height of the "pocket" formed below the lower edge of the ostium. Statistical analysis was performed using parametric and non-parametric statistical methods. Differences were considered significant at p ≤ 0.05. RESULTS: Intergroup differences were identified in the values of the maximum horizontal size of the bony "window" (p = 0.015), the maximum horizontal size of the soft tissue "window" (p < 0.001), the maximum vertical size of the soft tissue "window" (p < 0.001), and the height of the fragment of the remaining bone below the level of the common canaliculus to the edge of the formed ostium (p = 0.004). CONCLUSION: The stage of forming the bony "window" influences the success of DCR. Not only the position of the "window" is important, but also the geometric properties of the formed ostium.

Prognostic factors and outcome of relapsed/progressive pediatric Ewing sarcoma: single-center 10-year experience.

BACKGROUND: Ewing sarcoma (ES) is the second most common primary malignant bone tumor in children and adolescents. Despite more intensive chemotherapy regimens and improved local control therapy, there is still a considerable rate of recurrent/progressive disease. METHODS: A retrospective study of 50 relapsed/progressive ES patients who were treated at the National Cancer Institute (NCI), Cairo University, during the period from 1st of January 2008 to the end of December 2018, to assess different prognostic variables and disease outcomes. RESULTS: Out of fifty eligible cases, 32 patients (64%) had disease recurrence, and 18 (36%) developed disease progression on treatment. The median follow-up period was 7.4 months. The median overall survival (OS) was 7.5 months, and the cumulative OS was 64% at 6 months and 32.6% at 1 year. The cumulative event-free survival (EFS) was 41.3% at 6 months and 22.3% at 1 year. Patients with disease recurrence had better OS and EFS than patients with disease progression (p = 0.019). Patients who underwent local control at relapse/progression had a significantly better outcome than patients who received chemotherapy only (p < 0.001). Recurrence > 2 years from initial diagnosis was the only independent predictor of better survival outcome. CONCLUSIONS: Patients with relapsing/progressive ES portended a poor outcome, with disease progression on treatment faring worse than relapse. Better outcome was observed in patients who experienced recurrence > 2 years after diagnosis, patients with disease recurrence rather than disease progression on treatment, and patients who underwent local control along with intensive chemotherapy.

Severity and organ distribution of graft-versus-host disease with post-transplant cyclophosphamide versus calcineurin inhibitor plus methotrexate/mycophenolate mofetil or sirolimus in allogenic HLA-matched or single-allele mismatched stem cell transplantation.

OBJECTIVE: This retrospective single center study aims to describe changes in the severity and organ-specific distribution of GvHD, by comparing the outcomes of 3 distinct GvHD prophylaxis approaches. METHODS: Between January 2012 and June 2022, 226 patients underwent allogeneic hematopoietic stem cell transplantation from HLA-matched or 1-allele mismatched related or unrelated donors. Fifty-eight (26%) received prophylaxis with calcineurin inhibitor in combination with mycophenolate mofetil or a short course of methotrexate (Cohort-1), 87 (38%) tacrolimus plus sirolimus (Cohort-2), and 81 (36%) post-transplant cyclophosphamide (PTCy) plus tacrolimus (Cohort-3). RESULTS: The incidence of grade II-IV aGvHD was 69% vs. 41.4% vs. 27.2%; p < .01. The most significant reduction with PTCy was observed in both stage 3-4 skin and lower gastrointestinal (GI) involvement (p < .01). The incidence of moderate-to-severe cGvHD at 12 months was 34.5% vs. 34.5% vs. 6.2%; p < .01. Moderate-to-severe skin and GI cGvHD was less common after PTCy (p < .01). The 1-year GvHD-free/relapse-free survival was higher with PTCy (p < .01). CONCLUSIONS: Our study indicates that PTCy-based GvHD prophylaxis reduces the frequency and severity of both acute and chronic GvHD, with a notable decrease in severe GI and cutaneous manifestations. The higher GRFS may result in lower GvHD-related mortality, leading to an improved quality of life among survivors.

Identification of clinical-biological features of newly diagnosed early relapse multiple myeloma patients eligible for autologous stem cell transplantation.

A portion of multiple myeloma (MM) patients relapse early or do not respond to first line treatment. Identification of possible clinical and or biological features of these patients remains an unmet medical need. In this study we assesed the predictive markers for early relapse MM, defined as a progressive disease that occurred within 18 months, from autologoust stem cell transplantation (ASCT) in MM patients who did not have primary refractory disease. 74 consecutive MM patients were included in the study that received intensive therapy with ASCT. The study was able to identify the main features of newly diagnosed ER MM patients eligible for ASCT identifying the IgA isotype and the R2-ISS score system as the main predictive prognostic factors for ER in this cohort of MM patients.
