Efficacy and safety of camrelizumab plus apatinib compared to apatinib monotherapy as third-line or above therapy for metastatic colorectal cancer patients: A retrospective cohort study

This study aimed to investigate the treatment efficacy and safety of camrelizumab (programmed cell death protein-1 (PD-1) inhibitor) plus apatinib as third-line or above therapy in metastatic colorectal cancer (mCRC) patients. Totally, 64 unresectable mCRC patients receiving camrelizumab plus apatinib (N = 31) and apatinib (N = 33) were retrospectively enrolled. It was found that disease control rate and objective response rate (ORR) were increased in camrelizumab plus apatinib group compared to apatinib group, but ORR did not achieve statistical significance. Besides, the median (95% confidence interval [CI]) progressive-free survival (PFS) and overall survival (OS) were 6.9 (3.7–10.1) and 11.5 (7.7–15.3) months in camrelizumab plus apatinib group, as well as 3.6 (1.7–5.5) and 6.7 (5.0–8.4) months in apatinib group. Additionally, PFS and OS were prolonged in camrelizumab plus apatinib group compared with apatinib group. The incidence of a dverse events did not differ between groups. Conclusively, camrelizumab (PD-1 inhibitor) plus apatinib achieves a better treatment efficacy than apatinib as third-line or above therapy with a good safety profile in mCRC patients.


Abstract

What Is Known and Objective

Programmed cell death protein-1 (PD-1) inhibitors synergize apatinib for anti-tumour effect by regulating tumour microenvironment, vascular endothelial growth factor, hypoxia condition, immune response, etc. This study aimed to investigate the treatment efficacy and safety of camrelizumab (PD-1 inhibitor) plus apatinib as third-line or above therapy in metastatic colorectal cancer (mCRC) patients.

Methods

Totally, 64 unresectable mCRC patients receiving camrelizumab plus apatinib (N = 31) and apatinib (N = 33) were retrospectively enrolled.

Results

Disease control rate (80.6% vs. 57.6%) (P = 0.047) was elevated in camrelizumab plus apatinib group compared to apatinib group; however, objective response rate (22.6% vs. 6.1%) (P = 0.078) only showed an increasing trend but did not achieve statistical significance. Besides, the median (95% confidence interval [CI]) progressive-free survival (PFS) and overall survival (OS) were 6.9 (3.7–10.1) and 11.5 (7.7–15.3) months in camrelizumab plus apatinib group; meanwhile, the median (95% CI) PFS and OS were 3.6 (1.7–5.5) and 6.7 (5.0–8.4) months in the apatinib group. Additionally, PFS (P = 0.017) and OS (P = 0.006) were prolonged in camrelizumab plus apatinib group compared with apatinib group, which was confirmed by further multivariate Cox's proportional hazards regression analysis (hazard ratio [HR] = 0.340, P < 0.001 for PFS; HR = 0.271, P < 0.001 for OS). Th e incidence of total, grade 1–2, and grade 3–4 adverse events did not differ between groups (all P > 0.05).

Conclusion

Camrelizumab (PD-1 inhibitor) plus apatinib achieves a better treatment efficacy than apatinib as third-line or above therapy with a good safety profile in mCRC patients.

Mendelian randomization suggests a potential causal effect of eosinophil count on influenza vaccination responsiveness

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Currently, the clinical factors affecting immune responses to influenza vaccines have not been systematically explored. The mechanism of low responsiveness to influenza vaccination (LRIV) is complicated and not thoroughly elucidated. Thus, we integrate our in-house genome-wide association studies (GWAS) analysis result of LRIV (N = 111, Ncase [Low Responders] = 34, Ncontrol [Responders] = 77) with the GWAS summary of 10 blood-based biomarkers (sample size ranging from 62,076 to 108,794) deposited in BioBank Japan (BBJ) to comprehensively explore the shared genetics between LRIV and blood-based biomarkers to investigate the causal relationships between blood-based biomarkers and LRIV by Mendelian randomization (MR). The applications of four MR approaches (inverse-variance-weighted (IVW), weighted median, weighted mode, and generalized summary-data-based Mendelian randomization (GSMR)) suggested that the genetically instrumented LRIV was associated with decreased eosinophil count (� � = -5.517 to -4.422, p-value = 0.004 to 0.039). Finally, we conclude that the low level of eosinophil count is a suggestive risk factor for LRIV.

The prognostic significance of hematogones in childhood B‐cell acute lymphoblastic leukemia

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

Recent studies have demonstrated hematogones (HGs) expansion to be associated with favorable outcomes in hematological diseases, especially in patients with acute myeloid leukemia and patients undergoing hematopoietic stem cell transplantation. Acute lymphoblastic leukemia (ALL) is the most common form of cancer in children. As of now, minimal residual disease (MRD) remains the most compelling independent prognostic factor in childhood ALL. There is need for more prognostic tools for evaluating relapse risk.

Procedure

The goal of this study was to assess the prognostic value of HGs on relapse-free survival (RFS) and overall survival (OS) in childhood ALL. In this prospective cohort study, a total of 122 subjects with definitive diagnosis of precursor B lymphoblastic leukemia were evaluated. Flow cytometric HG detection was performed in bone marrow aspirates after induction and consolidation therapy.

Results

The median follow-up period of patients was 35.5 ± 9.4 (SD) months. Patients who had at least 1.0% HGs had a significantly better RFS (p = .023). Moreover, univariate and multivariate analyses confirmed that positive HGs were independently associated with longer RFS (unadjusted model: hazard ratio = 0.33, 95% CI = 0.12–0.91, p = .031; adjusted model: hazard ratio = 0.30, 95% CI = 0.11–0.82, p = .020).

Conclusions

Along with the role of MRD, our study shows the significance of HGs as an independent prognostic factor. The results indicate the independent prognostic value of HGs on RFS after adjustment for other prognostic factors, and can be beneficial for risk stratification and treatment modifications amongst pediatric B-cell ALL patients.

Duration of antibiotic treatment for acute graft pyelonephritis: What's the standard of care?

Duration of antibiotic treatment for acute graft pyelonephritis: What's the standard of care?


Abstract

Background

Limited evidence is available to inform the duration of antibiotic treatment in kidney transplant recipients with bacterial acute graft pyelonephritis. Guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation suggest a 14–21 day duration.

Methods

A four-question survey was constructed to determine the current standard of practice for the duration of treatment for acute graft pyelonephritis. The survey was distributed among members of the Infectious Diseases and the Kidney Pancreas Communities of Practice of the American Society of Transplantation.

Results

Among 144 survey respondents, 87 (60%) were infectious disease physicians, and 36 (25%) were transplant nephrologists. Although most (55%) respondents preferred a 14-day duration, a spread between 7 and 28 days was observed. Goals of treatment and drivers for longer duration differed between infectious disease physicians and transplant nephrologists.

Conclusions

Although most respondents prefer a 14-day duration of treatment for acute graft pyelonephritis, a wide range of responses was seen between 7 and 28 days. More evidence is needed to inform optimal treatment duration in this common infectious complication after transplantation.
