Application of thromboelastography to predict the severity of bleeding after chimeric antigen receptor (CAR)-T cell therapy in patients with hematological malignancy.

OBJECTIVES: We aim to analyze the predictive value of thromboelastography on bleeding severity of patients with chimeric antigen receptor (CAR)-T cell therapy. METHODS: A total of 80 patients with refractory/relapsed hematological malignancy were enrolled and divided into two groups: the severe bleeding group and the non-severe bleeding group. The thromboelastography data was collected on the day of CAR-T infusion and the 3rd, 7th, 10th, 13th, 17th, and 20th day after CAR-T cell infusion. RESULTS: The patients of the severe bleeding group had lower platelet (p < .007), maximum amplitude (p = .002), coagulation index (p = .005), and longer coagulation time (p = .019). Increasing trend in reaction time and coagulation time and decreasing trend in Alpha, maximum amplitude, and coagulation index on Days 0-10, opposite on Days 10-20. Univariate logistic regression analysis and multivariable logistic regression analysis showed maximum amplitude on the 3rd day after CAR-T cell infusion (MA3) (OR = 0.9; 95% CI = 0.84-0.95; p < .001) and cytokine release syndrome grade (OR = 2.57; 95% CI = 1.35-5.32; p = .006) were significantly associated with high bleeding severity. CONCLUSIONS: Thromboelastography was considered to be a good predictor of bleeding severity.

Succinate and mitochondrial DNA trigger atopic march from atopic dermatitis to intestinal inflammation.

BACKGROUND: Atopic march has long been recognized as the progression from atopic dermatitis (AD) to food allergy and asthma during infancy and childhood. However, effective blocking is hampered by the lack of specific biomarkers. OBJECTIVES: We aimed to investigate the pathologic progression of atopic march trajectories from skin to gut. METHODS: We built an atopic march mouse model by mechanical skin injury and percutaneous sensitization to peanut allergen. Anaphylaxis from the skin to the small intestine was then investigated by ELISA, RNA sequencing, quantitative real-time PCR, histopathologic analysis, and flow cytometry. The findings from the mice results were also verified by the serum samples of allergic pediatric patients. RESULTS: After modeling, inflammation in the skin and small intestine manifested as a mixed type of TH2 and TH17. Further analysis identified elevated succinate in the circulation and expanded tuft cells with upregulated IL-25 in the small intestine, resulting in increased intestinal type 2 innate lymphoid cells and an enhanced type 2 inflammatory response. In addition, free mitochondrial DNA (mtDNA) released after tissue damage was also involved in inflammation march from injured skin to small intestine through the STING pathway. Analysis of clinical samples verified that serum concentrations of succinate and mtDNA were higher in AD allergic children than non-AD allergic children. CONCLUSIONS: Succinate and mtDNA play key roles in skin-to-gut cross talk during the atopic march from AD to food allergy, and can be considered as biomarkers for risk assessment or targets for atopic march prevention strategies.

Derivation and validation of a novel score for early prediction of severe CRS after CAR-T therapy in haematological malignancy patients: A multi-centre study.

Chimeric antigen receptor T (CAR-T) cell therapy is highly effective in inducing complete remission in haematological malignancies. Severe cytokine release syndrome (CRS) is the most significant and life-threatening adverse effect of this therapy. This multi-centre study was conducted at six hospitals in China. The training cohort included 87 patients with multiple myeloma (MM), an external validation cohort of 59 patients with MM and another external validation cohort of 68 patients with acute lymphoblastic leukaemia (ALL) or non-Hodgkin lymphoma (NHL). The levels of 45 cytokines on days 1-2 after CAR-T cell infusion and clinical characteristics of patients were used to develop the nomogram. A nomogram was developed, including CX3CL1, GZMB, IL4, IL6 and PDGFAA. Based on the training cohort, the nomogram had a bias-corrected AUC of 0.876 (95% CI = 0.871-0.882) for predicting severe CRS. The AUC was stable in both external validation cohorts (MM, AUC = 0.907, 95% CI = 0.899-0.916; ALL/NHL, AUC = 0.908, 95% CI = 0.903-0.913). The calibration plots (apparent and bias-corrected) overlapped with the ideal line in all cohorts. We developed a nomogram that can predict which patients are likely to develop severe CRS before they become critically ill, improving our understanding of CRS biology, and may guide future cytokine-directed therapies.

Cytokine profiles are associated with prolonged hematologic toxicities after B-cell maturation antigen targeted chimeric antigen receptor-T-cell therapy.

BACKGROUND AIMS: The considerable efficacy of B-cell maturation antigen-targeted chimeric antigen receptor (CAR)-T-cell therapy has been extensively demonstrated in the treatment of relapsed or refractory multiple myeloma. Nevertheless, in clinical practice, prolonged hematologic toxicity (PHT) extends hospital stay and impairs long-term survival. METHODS: This retrospective study reviewed 99 patients with relapsed or refractory multiple myeloma who underwent B-cell maturation antigen CAR-T-cell therapy at our institution between April 2018 and September 2021 (ChiCTR1800017404). RESULTS: Among 93 evaluable patients, the incidence of prolonged hematologic toxicities was high after CAR-T-cell infusion, including 38.71% (36/93) of patients with prolonged neutropenia, 22.58% (21/93) with prolonged anemia and 59.14% (55/93) with prolonged thrombocytopenia. In addition, 9.68% (9/93) of patients experienced prolonged pancytopenia. Our multivariate analyses identified that cytokine profiles were independent risk factors for PHTs, whereas a sufficient baseline hematopoietic function and high CD4/CD8 ratio of CAR-T cells were protective factors for PHTs after CAR-T-cell infusion. Subgroup analyses found that the kinetics of post-CAR-T hematologic parameters were primarily determined by the collective effects of cytokine release syndrome and baseline hematopoietic functions, and showed influential weights for the three lineages. CONCLUSIONS: Our findings improve the understanding of the impact of cytokines on hematopoietic functions, which could contribute to the mechanism investigation and exploration of potential intervention strategies.

Associations of CXCL12 polymorphisms with clinicopathological features in breast cancer: a case-control study.

BACKGROUND: Previous studies suggested that CXCL12 was involved in the development, metastasis, and invasion of breast cancer, and genetic variants were associated with the diagnosis and prognosis of patients with breast cancer. The present study was aimed to assess the relationships between CXCL12 polymorphisms (rs1801157, rs2297630, and rs2839693) and susceptibility and clinicopathological features of breast cancer. METHODS: A case-control study was conducted in 434 breast cancer patients and 450 health controls. Student t-test and chi-square test were used to analyze the differences of age distribution and genotype frequencies between the two groups. Correlations between polymorphisms and clinical parameters were also assessed by chi-square test. The potential effects of the three polymorphisms on CXCL12 were investigated by the public database. RESULTS: A statistical association was found between CXCL12 rs1801157 polymorphism and breast cancer risk, possibility of metastasis, and estrogen receptor status. Patients with rs2839693 C/T or C/T-T/T genotypes were more likely to be progesterone receptor-negative. However, no associations of rs2297630 polymorphism with breast cancer risk or any clinicopathological characteristics were observed. In addition, rs2297630 affected the splicing quantitative trait loci of CXCL12 in the subcutaneous fat, rs2839693 polymorphism affected the splicing quantitative trait loci of CXCL12 in the human breast mammary tissues. CONCLUSIONS: Those results indicated that CXCL12 polymorphisms might be potential diagnostic indicators, and more investigation is needed in the future.

Immune signature-based risk stratification and prediction of immune checkpoint inhibitor's efficacy for lung adenocarcinoma.

BACKGROUND: Lung adenocarcinoma (LUAD) is a common pulmonary malignant disease with a poor prognosis. There were limited studies investigating the influences of the tumor immune microenvironment on LUAD patients' survival and response to immune checkpoint inhibitors (ICIs). METHODS: Based on TCGA-LUAD dataset, we constructed a prognostic immune signature and validated its predictive capability in the internal as well as total datasets. Then, we explored the differences of tumor-infiltrating lymphocytes, tumor mutation burden, and patients' response to ICI treatment between the high-risk score group and low-risk score group. RESULTS: This immune signature consisted of 17 immune-related genes, which was an independent prognostic factor for LUAD patients. In the low-risk score group, patients had better overall survival. Although the differences were non-significant, patients with low-risk scores had more tumor-infiltrating follicular helper T cells and fewer macrophages (M0), which were closely related to clinical outcomes. Additionally, the total TMB was markedly decreased in the low-risk score group. Using immunophenoscore as a surrogate of ICI response, we found that patients with low-risk scores had significantly higher immunophenoscore. CONCLUSION: The 17-immune-related genes signature may have prognostic and predictive relevance with ICI therapy but needs prospective validation.

Measuring the global, regional, and national burden of multiple myeloma from 1990 to 2019.

BACKGROUND: Multiple myeloma (MM) is a major health concern. Understanding the different burden and tendency of MM in different regions is crucial for formulating specific local strategies. Therefore, we evaluated the epidemiologic patterns and explored the risk factors for MM death. METHODS: Data on MM were collected from the 2019 Global Burden of Disease study. We used incidence, mortality, and disability adjusted life-years to estimate the global, regional, and national burden of MM. RESULTS: In 2019, there were 155,688 (95% UI, 136,585 - 172,577) MM cases worldwide, of which 84,516 (54.3%, 70,924 - 94,910) were of men. The age-standardized incidence rate (ASIR) was 1.72/100,000 persons (95% UI, 1.59-1.93) in 1990 and 1.92/100,000 persons (95% UI, 1.68-2.12) in 2019. The number of MM deaths increased 1.19-fold from 51,862 (95% UI, 47,710-58,979) in 1990 to 113,474 (95% UI, 99,527 - 121,735) in 2019; the age-standardized death rate (ASDR) was 1.42/100,000 persons (95% UI, 1.24-1.52) in 2019. In recent 15 years, ASDR showed a steady tendency for men, and a downward tendency for women. Countries with high social-demographic indexes exhibited a higher ASIR and ASDR. Australasia, North America, and Western Europe had the highest ASIR and ASDR, with 46.3% incident cases and 41.8% death cases. Monaco had the highest ASIR and ASDR, which was almost half as high as the second highest country Barbados. In addition, United Arab Emirates and Qatar had the largest growth multiple in ASIR and ASDR, which was twice the third country Djibouti. CONCLUSIONS: Globally, incident and death MM cases have more than doubled over the past 30 years. The increasing global burden may continue with population aging, whereas mortality may continue to decrease with the progression of medical technology. The global burden pattern of MM was diverse, therefore specific local strategies based on different burden patterns for MM are necessary.

Incidence and disease burden of prostate cancer from 1990 to 2017: Results from the Global Burden of Disease Study 2017.

BACKGROUND: The patterns of the incidence and mortality of prostate cancer (PC) have been changing over the years. In addition, the unclear etiology of PC necessitates further studies into the geographic distribution and age composition of patients with PC. This study was aimed at examining the patterns of the epidemiology of PC to help policymakers to allocate the limited resources of the health care system accordingly. METHODS: Annual case data and age-standardized rates (ASRs) were obtained for the incidence, mortality, and disability-adjusted life-years (DALYs) of PC according to age from 1990 to 2017 and for 21 regions, including 195 countries and territories. The estimated annual percentage changes (EAPCs) of ASRs were calculated to evaluate the incidence and mortality trends of PC. RESULTS: Worldwide, the age-standardized incidence rate (ASIR) of PC increased from 30.5 cases per 100,000 population in 1990 to 37.9 cases per 100,000 population in 2017 with an EAPC of 0.59 (95% confidence interval [CI], 0.49-0.7), whereas the mortality decreased with an EAPC of -0.73 (95% CI, -0.80 to -0.67). The ASIR was positively associated with the sociodemographic index (SDI) in most regions, and the increase in the ASIR was steeper with a higher SDI. The proportion of patients younger than 65 years increased from 23.6% in 1990 to 27.3% in 2017. CONCLUSIONS: The incidence of PC has been increasing globally, whereas its mortality and DALYs have been decreasing. These trends are particularly significant in developed regions and vary across geographic regions. Adjustments to the medical strategy by governments and medical institutions are required.

The Prognostic Value of the Number of Negative Lymph Nodes Combined with Positive Lymph Nodes in Esophageal Cancer Patients: A Propensity-Matched Analysis.

BACKGROUND: Currently, the number of negative lymph nodes (NLNs) has been paid increasing attention and is considered a prognostic indicator in diverse cancers. Therefore, it is necessary to explore the association between number of NLNs and prognosis in esophageal cancer (EC) patients. METHODS: Our data were obtained from the Surveillance, Epidemiology, and End Results 18 database. The X-tile plot was used to determine the optimal cut-off value of the number of NLNs, and propensity score matching (PSM) was performed according to the results of the X-tile plot. RESULTS: A total of 4777 patients were eligible, and 882 pairs of patients were included after PSM. The result of the X-tile plot revealed an optimal cut-off value of three NLNs. Multivariate Cox regression analysis revealed better EC-specific survival (ECSS) in patients with more than three NLNs (hazard ratio [HR] 0.68, 95% confidence interval [CI] 0.59-0.77; p < 0.001) compared with patients with three or fewer NLNs. A subgroup analysis revealed better ECSS in patients with more than three NLNs with one to two (HR 0.57, 95% CI 0.46-0.71; p < 0.001) or three to six (HR 0.68, 95% CI 0.50-0.92; p = 0.012) positive lymph nodes (PLNs). CONCLUSIONS: More than three NLNs is associated with better survival in EC patients, especially when the number of PLNs is one to two or three to six. We confirm that the combination of the number of NLNs and number of PLNs can provide better prognostic guidance for EC.

Scutellarin inhibits proliferation and invasion of hepatocellular carcinoma cells via down-regulation of JAK2/STAT3 pathway.

The prognosis of hepatocellular carcinoma (HCC) is poor because of high incidence of recurrence and metastasis. JAK/STAT signalling pathway regulates cell proliferation, apoptosis, differentiation and migration and epithelial-mesenchymal transition (EMT) is also considered to contribute to invasion and metastasis of epithelial malignant tumours. Scutellarin is an active component found in many traditional Chinese herbs and has been regularly used in anti-inflammatory and antitumour medicine. This study aimed to identify the effect of scutellarin and its possible mechanism of action in HCC cells. Proliferation, colony-forming, apoptosis and cell migration assays were used to examine the effect of scutellarin on HCC cells. Quantitative real-time PCR and Western blotting were performed to study the molecular mechanisms of action of scutellarin. Light and electron microscopy and immunofluorescence analysis were performed to study the effect of scutellarin on cellular mechanics. We show that scutellarin potentially suppresses invasiveness of HepG2 and MHCC97-H cells in vitro by remodelling their cytoskeleton. The molecular mechanism behind it might be the inhibition of the EMT process, which could be attributed to the down-regulation of the JAK2/STAT3 pathway. These findings may provide new clinical ideas for the treatment of liver cancer.

Hyperuricemia and gout are associated with cancer incidence and mortality: A meta-analysis based on cohort studies.

The association between hyperuricemia or gout and cancer risk has been investigated in various published studies, but their results are conflicting. We conducted a meta-analysis to investigate whether hyperuricemia or gout was associated with the cancer incidence and mortality. Linear and nonlinear trend analyses were conducted to explore the dose-response association between them. The pooled relative risk (RR) and 95% confidence interval (CI) were used to evaluate cancer risk. A total of 24 articles (33 independent studies) were eligible for inclusion. When compared participants with the highest SUA (hyperuricemia) levels and those with the lowest SUA levels, the pooled RR was 1.08 (95% CI, 1.04-1.12), it was significantly associated among males but not among females (males, RR = 1.07; 95% CI, 1.03-1.11; females, RR = 1.06; 95% CI, 0.96-1.17). Hyperuricemia increased total cancer mortality (RR = 1.15; 95% CI, 1.05-1.26), but a significant association was observed in females rather than in males (females: RR = 1.26; 95% CI, 1.09-1.45; males, RR = 1.02; 95% CI, 0.80-1.30). Linear relationships of SUA levels with overall cancer incidence (p for nonlinearity = 0.238) and overall cancer mortality (p for nonlinearity = 0.263) were identified. However, 1 mg/dL increment in SUA levels was weakly significant in overall cancer incidence (RR = 1.01; 95% CI, 1.01-1.01) but not associated with overall cancer mortality (RR = 1.01; 95% CI, 0.99-1.03). Gout was significantly associated with increased cancer incidence (RR = 1.19; 95% CI, 1.12-1.25). In conclusion, Hyperuricemia or gout was associated with higher cancer incidence and mortality. Though a potential linear relationship between them was found, we'd better treat this result with caution.

Impact of four lncRNA polymorphisms (rs2151280, rs7763881, rs1136410, and rs3787016) on glioma risk and prognosis: A case-control study.

Long noncoding RNA (lncRNA) polymorphisms are reportedly in connection with tumor susceptibility and prognosis. Glioma is one of the most aggressive and common cancers of the central nervous system. This study aimed to investigate the relationship between four lncRNA variants and glioma susceptibility and prognosis in a Chinese Han population. Sequenom Mass-ARRAY was used to genotype 605 patients with glioma and 1300 cancer-free individuals. Odds ratios or hazard ratios and related 95% confidence intervals were calculated to estimate the correlations. Logistic and Cox regression models, log-rank tests, and Kaplan-Meier curves were used for the statistical analysis. Six inheritance models showed that ANRIL rs2151280 variant genotype (A>G) was related to the susceptibility of glioma, while the other three lncRNAs showed no association. Patients treated with temozolomide or nimustine had better progression-free survival (PFS) and overall survival (OS) than those treated with platinum. Besides, patients aged older than 40 years showed a poorer OS. The Cox multivariate analysis revealed that the rs1136410 GG genotype (A>G) was beneficial for OS and PFS. The Kaplan-Meier analyses indicated that rs1136410 A>G and the rs7763881 A>C were associated with longer OS. ANRIL rs2151280 variant genotype might increase susceptibility of glioma. In addition, PARP1 rs1136410 variant genotype could be beneficial for the overall survival of patients with glioma. More research data are needed to further validate our results.

GSTM1 and GSTT1 null genotype increase the risk of hepatocellular carcinoma: evidence based on 46 studies.

BACKGROUND: It is well known that hepatocellular carcinoma (HCC) has been one of the most life-threatening diseases all over the world. Plenty of internal and extrinsic factors have been proven to be related to HCC, such as gene mutation, viral hepatitis, and Nitrosamines. Though previous studies demonstrated that glutathione S-transferase (GST) genotypes are associated with HCC, the conclusions are inconsistent. Therefore, we carried on a renewed meta-analysis to expound the connection between the null GSTM1, GSTT1 polymorphisms and the risk of HCC. METHODS: We searched PubMed, Web of Science, Embase, and CNKI databases to select qualified researches which satisfied the inclusion criteria up to July 31, 2018. Finally, we selected 41 articles with 6124 cases and 9781 controls in this meta-analysis. We use ORs and 95% confidence interval (CI) to evaluate the correlation intension between the GSTM1 and GSTT1 null genes and the risk of HCC. All the statistical processes were executed by Stata (version 12.0). RESULTS: The pooled analysis showed that both GSTM1 null genotypes (OR = 1.37, 95% CI = 1.18-1.59) and GSTT1 null genotypes (OR = 1.43, 95% CI = 1.23-1.66) increased the risk of HCC. And GSTM1-GSTT1 dual-null genotypes also increased the risk of HCC (OR = 1.58, 95% CI = 1.22-2.05). In the subgroup analysis, we obtained significant results among Asians when stratified by race, and the results are GSTM1 null OR = 1.44, 95% CI = (1.22-1.71), GSTT1 null OR = 1.48, 95% CI = (1.25-1.77), GSTM1-GSTT1 null OR = 1.58, 95% CI = (1.19-2.09), while we didn't obtain significant results among Caucasians or Africans. Stratified analyses on the type of control indicated a higher risk of HCC associated with GSTM1, GSTT1 single null genotypes and GSTM1-GSTT1 dual-null genotypes in healthy people. No evidence of significant connection was discovered in chronic liver disease (CLD) except in GSTT1 single null. CONCLUSIONS: Our study indicated that an individual who carries the GSTM1, GSTT1 single null genotypes and GSTT1-GSTM1 dual-null genotypes is more likely to develop HCC.

Genetic polymorphisms of estrogen receptor genes are associated with breast cancer susceptibility in Chinese women.

BACKGROUND: Estrogen exposure is a widely known risk factor for BC. And the interaction of estrogen with estrogen receptor (ER) plays an important role in breast cancer development. This case-control study aims to assess the association of genetic polymorphisms in the estrogen receptor genes with breast cancer (BC) susceptibility in Chinese Han women. METHODS: Four polymorphisms (rs2881766, rs9383951, rs9340799 in ESR1 and rs3020449 in ESR2) were genotyped in 459 patients and 549 healthy controls using the Sequenom MassARRAY method. Odds ratio (OR) and 95% confidence intervals (95% CI) were calculated to evaluate the associations. False-positive report probability (FPRP) was utilized to examine the noteworthiness of significant findings. RESULTS: We observed that rs2881766 was associated with a decreased BC risk (GG vs. TT: OR = 0.63, 95% CI = 0.44-0.91; GG vs. TT/GT: OR = 0.68, 95% CI = 0.49-0.95), while rs3020449 was associated with an increased risk of BC (CT vs. TT: OR = 1.58, 95% CI = 1.21-2.06; CT/CC vs. TT: OR = 1.54, 95% CI = 1.20-1.98; TT/CC vs. CT: OR = 1.48, 95% CI = 1.15-1.90). The other two polymorphisms have no relation with BC susceptibility. In addition, rs2881766 was correlated with lymph node metastasis and ER expression, and rs3020449 was related to tumor size, histological grade and ER expression. The values of false-positive report probability indicated that the significant associations of BC risk with both rs2881766 and rs3020449 were noteworthy. CONCLUSIONS: Our study suggests that polymorphisms rs2881766 and rs3020449 in estrogen receptor genes were associated with BC susceptibility as well as clinical features in Chinese women. These findings need further validation in a large population.

Continuous renal replacement therapy in children with multiple organ dysfunction syndrome: a case series.

There is a lack of definitive information regarding the precise indications, implementation, and outcomes of continuous renal replacement therapy (CRRT) for the treatment of critically ill children. Six children (three boys, three girls) aged from 3 days to 8 years, all of whom had multiple organ failure, were submitted to bedside CRRT using M60 filter membranes. Modified Port carbonate formula was used and clotting time was maintained between 20 and 30 minutes. Activated partial thromboplastin time was 1.5- to 2-fold normal. One patient discontinued treatment due to family decision. Marked improvements were seen in the remaining five patients, including normalization of blood urea nitrogen and creatinine levels, stabilization of electrolytes, and improvements in markers of organ function. Of note, one patient (a six-year-old male) underwent the treatment for 241 hours. All five patients were subsequently discharged and recovered uneventfully. CRRT is effective for the management of children who are critically ill due to multiple organ failure.

Characterization of gut microbiota in patients with stage 3-4 chronic kidney disease: a retrospective cohort study.

PURPOSE: Multiple factors, such as dietary patterns, pharmaceutical interventions, and exposure to harmful substances, possess the capacity to influence gut microbiota composition. Gut microbiota dysbiosis has emerged as a significant contributor to the progression of chronic kidney disease (CKD) and its associated complications. By comprehending the intricacies of the intestinal microbiota, this research endeavor holds the potential to offer novel perspectives on potential strategies for mitigating CKD progression. METHODS: In this retrospective analysis, we assessed gut microbiota composition in CKD patients. Fecal samples were collected from a cohort of 44 patients with stage 3-4 CKD, alongside a control group consisting of 132 healthy volunteers. Subsequently, 16 s rDNA sequencing was conducted to examine the composition of the gut microbiota. RESULTS: Our findings revealed significant alterations in the diversity of intestinal microbiota in fecal samples between patients with stage 3-4 CKD and healthy subjects. Among the 475 bacterial genera, 164 were shared, while 242 dominant genera were exclusive to healthy subjects and 69 to CKD stages 3-4 samples. Notably, healthy volunteers exhibited a prevalence of intestinal Firmicutes and Bacteroidetes, whereas stage 3-4 CKD patients displayed higher abundance of Proteobacteria and Actinobacteria. The presence of uncultured Coprobacillus sp. notably contributed to distinguishing between the two groups. ROC curve analysis identified distinct microbiota with superior diagnostic efficacy for discriminating stage 3-4 CKD patients from healthy individuals. Metabolic pathway analysis revealed differing dominant pathways between the two groups-the NADH dehydrogenase pathway in healthy individuals and the phosphate acetyltransferase pathway in stage 3-4 CKD patients. Moreover, the CKD cohort displayed a higher proportion of Gram-negative bacteria and facultative anaerobes. CONCLUSIONS: In conclusion, our study underscores the profound influence of gut microbiota dysbiosis on CKD progression. The distinct microbial profiles observed in CKD patients highlight the potential efficacy of microbiota-based interventions in mitigating CKD advancement.

Cytokine-based models for efficient differentiation between infection and cytokine release syndrome in patients with hematological malignancies.

Although the efficacy of chimeric antigen receptor (CAR)-T cell therapy has been widely demonstrated, its clinical application is hampered by the complexity and fatality of its side effects. Cytokine release syndrome (CRS) is the most common toxicity following CAR-T cell infusion, and its symptoms substantially overlap with those of infection. Whereas, current diagnostic techniques for infections are time-consuming and not highly sensitive. Thus, we are aiming to develop feasible and efficient models to optimize the differential diagnosis in clinical practice. This study included 191 febrile patients from our center, including 85 with CRS-related fever and 106 with infectious fever. By leveraging the serum cytokine profile at the peak of fever, we generated differential models using a classification tree algorithm and a stepwise logistic regression analysis, respectively. The first model utilized three cytokines (IFN-ß, CXCL1, and CXCL10) and demonstrated high sensitivity (90% training, 100% validation) and specificity (98.44% training, 90.48% validation) levels. The five-cytokine model (CXCL10, CCL19, IL-4, VEGF, and CCL20) also showed high sensitivity (91.67% training, 95.65% validation) and specificity (98.44% training, 100% validation). These feasible and accurate differentiation models may prompt early diagnosis of infections during immune therapy, allowing for early and appropriate intervention.

Tenapanor in Chinese ESRD patients with hyperphosphatemia on haemodialysis: a randomised, phase 3 trial.

Background: The efficacy and safety of tenapanor has not been confirmed in Chinese end-stage renal disease (ESRD) patients with hyperphosphatemia on haemodialysis (HD). Methods: This was a randomised, double blind, phase 3 trial conducted at 26 dialysis facilities in China (https://www.chictr.org.cn/index.aspx; CTR20202588). After a 3-week washout, adults with ESRD on HD with hyperphosphatemia were randomised (1:1) using an interactive web response system to oral tenapanor 30 mg twice a day or placebo for 4 weeks. The primary endpoint was the change in mean serum phosphorous level from baseline to the endpoint visit (day 29 or last serum phosphorus measurement). Efficacy was analysed in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of the study drug. Results: Between 5 March 2021 and 8 June 2022, 77 patients received tenapanor and 73 received placebo. Tenapanor treatment (n = 75) resulted in a significantly greater least squares (LS) mean reduction in serum phosphate at the endpoint visit versus placebo (n = 72): LS mean difference -1.17 mg/dl (95% CI -1.694 to -0.654, P < .001). More patients receiving tenapanor achieved a serum phosphorous level <5.5 mg/dl at the endpoint visit (44.6% versus 10.1%). The most common treatment-related adverse event was diarrhoea [tenapanor 28.6% (22/77), placebo 2.7% (2/73)], which was mostly mild and led to treatment discontinuation in two patients receiving tenapanor. Conclusions: Tenapanor significantly reduced the serum phosphorous level versus placebo in Chinese ESRD patients on HD and was generally well tolerated.
