Value of leukocytosis and elevated C-reactive protein in predicting severe coronavirus 2019 (COVID-19): A systematic review and meta-analysis. Clin Chim Acta 2020; 509:235-243. [PMID: 32533986 PMCID: PMC7832771 DOI: 10.1016/j.cca.2020.06.008] [Citation(s) in RCA: 55] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 05/31/2020] [Accepted: 06/03/2020] [Indexed: 01/08/2023]
Abstract
BACKGROUND Since December 2019, coronavirus 2019 (COVID-19) has spread worldwide. Identifying poor prognostic factors is helpful for risk stratification. In this meta-analysis, we investigated the association between severe COVID-19 and a change in white blood cell (WBC) count, an elevation of C-reactive protein (CRP), and fever. Moreover, we aimed to evaluate the diagnostic accuracy of leukocytosis and an elevation of CRP. METHODS We performed a systematic search of PubMed, EMBASE, Scopus, and the Cochrane Library through April 20th, 2020. The odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. A sensitivity analysis was conducted according to the study size (>200 or <200) and median age (>55 or <55). Meta-regression analyses were conducted to examine possible sources of heterogeneity. We calculated the diagnostic accuracy of leukocytosis and CRP. RESULTS Eighteen studies with 3278 patients were selected. Fever, leukocytosis, and elevated CRP were associated with poor outcomes (OR (95% CI) 1.63 (1.06-2.51), 4.51 (2.53-8.04), and 11.97 (4.97-28.8), respectively). Leukopenia was associated with a better prognosis (OR 0.56, 95% CI 0.40-0.78). Sensitivity analyses showed similar tendencies. Meta-regression analysis for leukocytosis indicated that age, dyspnea, and hypertension contributed to heterogeneity. The pooled area under the leukocytosis and CRP curves were 0.70 (0.64-0.76) and 0.89 (0.80-0.99), respectively. CONCLUSION In patients with COVID-19, fever, leukocytosis, and an elevated CRP were associated with severe outcomes. Leukocytosis and CRP on arrival may predict poor outcomes.

Abstract
BACKGROUND Skeletal-related events (SREs) are critical events for patients with bone metastasis from non-small cell lung cancer (NSCLC). Thus, bone-modifying agents are recommended in this population. However, the baseline risk factors of SREs in patients with bone metastasis from NSCLC are not well established. METHODS We analyzed the patient-level data from the zoledronate arm of a clinical trial comparing denosumab with zoledronate in patients with bone metastasis ( ClinicalTrial.gov ID: NCT00330759) available at Project Data Sphere, a broad-access research platform. The primary endpoint was the first SRE from the inclusion to the trial, and the time to the first SRE was analyzed using Cox proportional hazards model. RESULTS We analyzed 302 patients with NSCLC without a documented history of osteopenia or osteoporosis included in the zoledronate arm of the trial. Ninety-eight patients (32%) had at least one SRE. The univariate analysis showed that low serum albumin and elevated serum alkaline phosphatase (ALP) are significant baseline risk factors for SREs (hazard ratio (HR) [95% confidence interval (CI)]; 2.27 [1.43-3.61], and 1.91 [1.26-2.90], respectively). Additionally, osteoblastic and mixed type of bone metastasis showed a significantly lower risk of SREs compared with the osteolytic lesion (HR [95% CI]; 0.39 [0.21-0.72], and 0.31 [0.15-0.63], respectively). These factors also showed a significant association with the risk of SREs in multivariate analysis. CONCLUSIONS We revealed that osteolytic bone metastasis, low serum albumin, and elevated serum ALP are risk factors for SREs in patients with bone metastasis from NSCLC.

Abstract
BACKGROUND The best regimen of neo-adjuvant therapy for triple-negative breast cancer (TNBC) is unknown. Recent studies have shown promising data that adding carboplatin or pembrolizumab improves the rate of pathologic complete response (pCR) in TNBC. Therefore, we performed a network meta-analysis to define the overall, most effective, neo-adjuvant systemic therapy for TNBC. METHODS We searched for studies comparing different neo-adjuvant regimens in patients with TNBC. We performed a network meta-analysis comparing the regimens using the random-effects model. We focused on anthracycline, bevacizumab, pembrolizumab, and platinum salts (Pl). All study regimens contained a taxane. We analyzed the rate of pCR (ypT0/is, N0), and the incidence of febrile neutropenia, grade 3-grade 4 thrombocytopenia, nausea/vomiting, and diarrhea. RESULTS We identified a total of 13 randomized control trials for this analysis. We compared ten different classes of regimens. We found that regimens containing Pl were significantly superior to non-PI-containing regimens for the rate of pCR. Similarly, pembrolizumab-containing regimens were associated with significantly higher pCR rates. Regimens containing bevacizumab significantly increased the rate of pCR as well. However, it was equivocal as to whether the addition of Pl to pembrolizumab-containing regimen increases pCR rates. Adding anthracycline into the regimen did not show an improved rate of pCR. In the safety analysis, regimens containing Pl were associated with a significantly higher incidence of febrile neutropenia and grade 3-grade 4 thrombocytopenia. The regimen containing anthracycline plus bevacizumab plus Pl was associated with a higher risk of gastrointestinal adverse events. CONCLUSIONS For TNBC, regimens containing bevacizumab, pembrolizumab, or Pl are most effective in terms of pCR rates, though it is unclear whether combining all these medications has the greatest efficacy. Additionally, the benefit of using anthracycline in the neo-adjuvant therapy regimen for TNBC is not apparent, which may warrant a further head-to-head comparison.

Abstract
We report that two widely-used drugs for erectile dysfunction, tadalafil and vardenafil, trigger bone gain in mice through a combination of anabolic and antiresorptive actions on the skeleton. Both drugs were found to enhance osteoblastic bone formation in vivo using a unique gene footprint and to inhibit osteoclast formation. The target enzyme, phosphodiesterase 5A (PDE5A), was found to be expressed in mouse and human bone as well as in specific brain regions, namely the locus coeruleus, raphe pallidus, and paraventricular nucleus of the hypothalamus. Localization of PDE5A in sympathetic neurons was confirmed by coimmunolabeling with dopamine β-hydroxylase, as well as by retrograde bone-brain tracing using a sympathetic nerve-specific pseudorabies virus, PRV152. Both drugs elicited an antianabolic sympathetic imprint in osteoblasts, but with net bone gain. Unlike in humans, in whom vardenafil is more potent than tadalafil, the relative potencies were reversed with respect to their osteoprotective actions in mice. Structural modeling revealed a higher binding energy of tadalafil to mouse PDE5A compared with vardenafil, due to steric clashes of vardenafil with a single methionine residue at position 806 in mouse PDE5A. Collectively, our findings suggest that a balance between peripheral and central actions of PDE5A inhibitors on bone formation together with their antiresorptive actions specify the osteoprotective action of PDE5A blockade.

Abstract
Background Measuring emotional status objectively is challenging, but voice pattern analysis has been reported to be useful in the study of emotion. Objective The purpose of this pilot study was to investigate the association between specific sleep measures and the change of emotional status based on voice patterns measured before and after nighttime sleep. Methods A total of 20 volunteers were recruited. Their objective sleep measures were obtained using a portable single-channel electroencephalogram system, and their emotional status was assessed using MIMOSYS, a smartphone app analyzing voice patterns. The study analyzed 73 sleep episodes from 18 participants for the association between the change of emotional status following nighttime sleep (Δvitality) and specific sleep measures. Results A significant association was identified between total sleep time and Δvitality (regression coefficient: 0.036, P=.008). A significant inverse association was also found between sleep onset latency and Δvitality (regression coefficient: –0.026, P=.001). There was no significant association between Δvitality and sleep efficiency or number of awakenings. Conclusions Total sleep time and sleep onset latency are significantly associated with Δvitality, which indicates a change of emotional status following nighttime sleep. This is the first study to report the association between the emotional status assessed using voice pattern and specific sleep measures.

Abstract
BACKGROUND Skeletal-related events (SREs) are significant contributors to the morbidity and mortality in patients with bone metastasis from breast cancer. Thus, bone-modifying agents (BMAs) are recommended in this population. However, the baseline risk factors of SREs in patients with bone metastasis from breast cancer receiving BMAs are not well understood. METHODS We analyzed the patient-level data from a controlled arm of a clinical trial comparing denosumab with zoledronate in patients with bone metastases from breast cancer (ClinicalTrial.gov ID: NCT00321464) available at Project Data Sphere, a broad-access research platform that collects and curates patient-level data from completed, phase III cancer trials. The primary endpoint was the first SRE after the inclusion to the trial. The time to the first on study SRE was analyzed using Cox proportional hazards model based on patients' baseline characteristics including age, race, ECOG performance status (PS), histology and immunohistochemistry of breast cancer, and urine and serum laboratory data. RESULTS Among 756 patients in the zoledronate arm of the trial, we excluded 64 patients with a documented history of osteopenia or osteoporosis. The median age of the patients was 56 years old, the median follow-up was 553 days, and 249 patients (36%) had SREs. The univariate analysis showed that black or African American heritage, ECOG PS > 0, human epidermal growth factor receptor 2 (HER2) positivity, high urine N-telopeptide cross-links / creatinine ratio (NTx/Cre), and elevated serum alkaline phosphatase (ALP) are significant baseline risk factors for SREs. Patients with the characteristics of ECOG PS > 0, HER2 positivity, and elevated ALP also showed a significantly higher hazard ratio of SREs in multivariate analysis. CONCLUSIONS We determined risk factors for SREs in patients with bone metastasis from breast cancer.

Abstract
e15087 Background: Programmed death 1 (PD-1) inhibitors and Programmed Death-Ligand 1 (PD-L1) inhibitors are immune checkpoint inhibitors (ICIs) approved for treatment of several different cancers. Colitis is a major immune-related adverse event associated with ICIs, but the risk of colitis with PD-1 versus PD-L1 inhibitors is not well characterized. Methods: We performed a meta-analysis for the incidence of all grade and grade 3-4 colitis with PD-1 inhibitor (nivolumab, pembrolizumab, and cemiplimab) or PD-L1 inhibitor (atezolizumab, avelumab, and durvalumab) monotherapy using a fixed effects model. We also conducted subgroup meta-analyses of non-small cell lung cancer (NSCLC) or urothelial carcinoma (UC) trials, and a network meta-analysis of randomized trials comparing PD-1 or PD-L1 inhibitors with docetaxel for NSCLC. We analyzed Food and Drug Administration Adverse Event Reporting System (FAERS) database to estimate the reporting odds ratio (ROR) of each medication, which provides the estimated relative risk most valid in spontaneous report database. Results: We identified 88 studies that met inclusion for the analysis. PD-1 inhibitors were associated with higher incidence of all grade and grade 3-4 colitis compared to PD-L1 inhibitors in the analysis of all cancer types (1.49% vs 0.83%, relative risk (RR); 1.80, 95% confidence interval (CI); 1.22-2.67 for all grade colitis, and 0.85% vs 0.34%, RR; 2.52, 95% CI; 1.46-4.37 for grade 3-4 colitis). The meta-analyses on NSCLC and UC, and the network meta-analysis on NSCLC also showed the tendency that PD-1 inhibitors are associated with higher risk of all grade and grade 3-4 colitis, though only the analysis on UC for all grade colitis showed a significant difference. (1.95% vs 0.64%, RR; 3.05, 95% CI; 1.18 - 7.88) Retrospective analysis showed ROR of 16.78 (95% CI; 15.8-17.8) for PD-1 inhibitors, and 12.93 (95% CI; 10.74-15.42) for PD-L1 inhibitors. We found that ROR of PD-1inhibitors was 1.17 (95% CI; 0.97-1.43) compared to PD-L1 inhibitors. Conclusions: Our study showed that PD-1 inhibitors have higher risk of colitis than PD-L1 inhibitors.

Abstract
e12635 Background: The best regimen for neoadjuvant chemotherapy for triple-negative breast cancer (TNBC) is unknown. Recent studies have shown promising data that adding carboplatin improves the rate of pathological complete response (pCR) in TNBC). Therefore, we performed a network meta-analysis to define the overall most effective neoadjuvant systemic therapy for TNBC. Methods: We searched MEDLINE, Cochrane Library, and EMBASE from inception to December 2019 for studies comparing the efficacy of different neoadjuvant regimens in patients with TNBC. We performed a network meta-analysis comparing the regimens in the selected studies using the random-effects model. We focused on anthracycline (A), bevacizumab (B), everolimus (E), and platinum salts (Pl) because these are the medications commonly added to taxane based regimens. All studies contained a taxane regimen. We analyzed the rate of pCR (ypT0/is, N0) and the incidence of grade 3-4 neutropenia, thrombocytopenia, nausea/vomiting, and diarrhea. Results: We identified a total of 13 randomized control trials for this analysis. We compared eight different classes of regimens. We found that regimens containing Pl were significantly superior to Pl non-containing regimens for the rate of pCR. (risk ratio (RR) for pCR [95% confidence interval (CI)]: 1.66 [1.19-2.31], 1.37 [1.14-1.64], and 1.36 [1.14-1.62] for no medications of special interest vs Pl, A vs A+Pl, and A+B vs A+B+Pl, respectively). Regimens containing B were associated with a significantly better rate of pCR. (RR for pCR [95% CI]: 1.24 [1.06-1.46] and 1.23 [1.01-1.51] for A vs A+B and A+Pl vs A+B+Pl, respectively) In contrast, adding A into the regimen did not improve the rate of pCR. In the safety analysis, regimens containing Pl were associated with a significantly higher incidence of grade 3-4 neutropenia and thrombocytopenia. Regimens containing B showed a higher incidence of grade 3-4 nausea/vomiting, and diarrhea. Conclusions: For TNBC, adding Pl or B into the neoadjuvant therapy regimen brings about a higher pCR rate, though they are associated with an increase in hematologic or gastrointestinal complications. The benefit of adding A to the neoadjuvant chemotherapy regimen for TNBC is not apparent.

Abstract
PURPOSE The data of head-to-head comparisons of the anti-fracture efficacy of bone modifying agents (BMAs) in patients with hormone receptor-positive breast cancer receiving aromatase inhibitor (AI) are not available. Therefore, we conducted a network meta-analysis to compare the efficacy of different BMAs in patients with breast cancer receiving adjuvant AI. METHODS We performed a network meta-analysis to compare the change of bone mineral densities (BMDs) and the risk of fracture in the selected studies using a random effect model. The primary outcomes are the change of BMD of lumbar spine (LS) and total hip (TH) from the baseline (ΔBMD, %) at 1 and 2 years and the risk of fracture. RESULTS We identified and included a total of 16 randomized controlled trials for this analysis. All BMAs included (risedronate, zoledronate, and denosumab) were associated with a significant increase in BMD of LS and TH at 1 and 2 years compared with no upfront treatment group. Among BMAs, zoledronate and denosumab use resulted in significantly higher BMD of LS and TH at 1 and 2 years compared with risedronate. The risk of fracture was significantly lower in the patients who received denosumab or risedronate compared with the patients without upfront treatment (Relative risk (RR) [95% CI] 0.51 [0.38-0.67] and 0.54 [0.35-0.83], respectively). CONCLUSION Among the bisphosphonates, zoledronate increased BMD the most, but risedronate, not zoledronate, use was associated with lower risk of fracture. Denosumab increased BMD not only of LS but also of the cortical-bone-rich hip, and showed a significant reduction of fracture risk.

Abstract
Abstract
Background
In recent years it has been attempted to use a distal radial artery (DRA) as a puncture site for cardiac catheterization and intervention. A patency of radial artery is important in hemodialysis patients because the radial artery is source as an arteriovenous shunt. However, the incidence of radial artery occlusion (RAO) is not known after DRA puncture.
Purpose
To compare RAO rates after DRA puncture between dialysis and non-dialysis patients.
Method
This was retrospective, observational and single center study. All consecutive 1,533 patients undergoing DRA puncture were analyzed. The primary endpoint is RAO rates. The secondary endpoint is composite bleeding adverse event rates. These endpoints were evaluated by a vascular echocardiography several hours or the next day after the procedure.
Result
Among 1,533 patients, 26 were dialysis patients and 1,504 were non-dialysis patients. 1,386 people (90.5%) succeeded in puncture. Radial artery occlusion occurred in 7 patients (0.4%), all of whom were non-dialysis patients. There was no significant difference of RAO rate in dialysis patients and non-dialysis patients.
Conclusion
When performing DRA puncture, the probability of radial artery occlusion is not higher in dialysis patients than non-dialysis patients. The DRA puncture may be one of the option as puncture site even in dialysis patients.

Abstract
Bacterial peritonitis, an infection of the ascitic fluid, can be classified etiologically as spontaneous or secondary bacterial peritonitis. The former is mainly caused by portal hypertension and its subsequent effects, whereas the latter is caused by the direct dissemination of bacteria into the peritoneal cavity. Previous reports have described some distinguishing features of these two entities. Here, we report the first known case of bacterial peritonitis with Aeromonas hydrophilia and Escherichia coli in a patient with malignant ascites associated with pancreatic carcinoma who exhibited features of both spontaneous and secondary peritonitis. Our report suggests that clinicians should also consider bacterial peritonitis in patients with malignant ascites who present with ostensibly cancer-related symptoms.

Abstract
This study investigated a case of spindle cell carcinoma (SpCC) in tongue pathological lesions. The patient experienced a local recurrence and distant metastasis after surgical intervention. Although standard chemotherapy was administered, a granulomatous mass continued to develop. This aggressive growth led to survival of the tumor. Secondary debulking surgery was performed to improve the patient's quality of life at the request of the patient. Using a tissue sample derived from the secondary debulking surgery, we performed an analysis of the tumor's cell surface antigens, differentiation potential, metastatic ability, and inhibition potential by anticancer reagents. In vitro analysis revealed that the cell population grown under adherent culture conditions expressed the mesenchymal stem cell (MSC) markers CD73, CD90, and CD105. The cell line established from this SpCC contained colony-forming unit fibroblasts (CFU-Fs) and exhibited multipotent differentiation into several mesenchymal lineages, including bone, cartilage, and fat. The SpCC cells also displayed vigorous mobilization. These characteristics suggested that they had the differentiation potential of mesenchymal cells, especially MSCs, rather than that of epithelial cells. The surgical specimen analyzed in this study resisted the molecular target reagent cetuximab, which is an epidermal growth factor receptor inhibitor. This clinical insight revealed that chemotherapy-resistant SpCC cells have different characteristics compared to most other cancer cells, which are sensitive to cetuximab. Our cell death assay revealed that SpCC cell death was induced by the anticancer drug imatinib, which is known to inhibit protein tyrosine kinase activity of ABL, platelet-derived growth factor receptor α (PDGFRα), and KIT. Here, we report recurrent SpCC with characteristics of MSCs and potential for treatment with imatinib.

Synergistic anti-AML effects of the LSD1 inhibitor T-3775440 and the NEDD8-activating enzyme inhibitor pevonedistat via transdifferentiation and DNA rereplication. Oncogenesis 2017; 6:e377.

Abstract
Lysine-specific demethylase 1A (LSD1, KDM1A) specifically demethylates di- and monomethylated histones H3K4 and K9, resulting in context-dependent transcriptional repression or activation. We previously identified an irreversible LSD1 inhibitor T-3775440, which exerts antileukemic activities in a subset of acute myeloid leukemia (AML) cell lines by inducing cell transdifferentiation. The NEDD8-activating enzyme inhibitor pevonedistat (MLN4924, TAK-924) is an investigational drug with antiproliferative activities in AML, and is also reported to induce cell differentiation. We therefore tested the combination of these two agents in AML models. The combination treatment resulted in synergistic growth inhibition of AML cells, accompanied by enhanced transdifferentiation of an erythroid leukemia lineage into granulomonocytic-like lineage cells. In addition, pevonedistat-induced rereplication stress during the S phase was greatly augmented by concomitant treatment with T-3775440, as reflected by the increased induction of apoptosis. We further demonstrated that the combination treatment was markedly effective in subcutaneous tumor xenograft models as well as in a disseminated model of AML, leading to tumor eradication or prolonged survival in T-3775440/pevonedistat cotreated mice. Our findings indicate the therapeutic potential of the combination of LSD1 inhibitors and pevonedistat for the treatment of AML.

Abstract
In recent years, proactive surgical treatment has been reported to be effective for medication-related osteonecrosis of the jaw (MRONJ). However, an uncertain resection entails the risk of recurrence, whereas an extensive surgical procedure may lead to a marked reduction in quality of life as a result of reduced masticatory function and poor cosmesis. Therefore, radiological assessment can be helpful to accurately localize MRONJ before surgery. The integrated single-photon emission computed tomography and computed tomography system (SPECT/CT) allows oral and maxillofacial surgeons to identify an area of MRONJ, especially when three-dimensional (3D) SPECT and CT fusion images are offered. A patient for whom 3D SPECT and CT image fusion (as developed in the radiology department of the study institution) contributed to determining the extent of the lesion, thereby leading to a favourable patient prognosis, is reported herein. There was exact correlation between the histological and radiological results.

Abstract
OBJECTIVE The present study was designed to investigate whether titres of antibody to two strains of Porphyromonas gingivalis, FDC381 and SU63, are associated with serum high-sensitivity C-reactive protein (hs-CRP) levels in Japanese periodontitis patients. DESIGN Forty-nine patients with moderate to advanced periodontitis and 40 periodontally healthy control subjects were included in this study. hs-CRP levels and antibody titres to P. gingivalis were measured at baseline and reassessment 3-4 months after periodontal treatment in periodontitis patients as well as at the time of examination in the periodontally healthy subjects. Further, the effect of periodontal therapy, including surgical treatment and use of antibacterials on both markers, was analysed in patients. RESULTS hs-CRP levels and antibody titres to P. gingivalis were higher in periodontitis patients than in control subjects, and they significantly decreased following periodontal treatment (p < 0.005). Also, a significant decrease in hs-CRP levels as a result of periodontal treatment was found in patients with hs-CRP levels >1 mgl(-1) at baseline (p < 0.005). Probing depth, clinical attachment level, and alveolar bone loss in patients were significantly associated with a higher antibody titre to both strains of P. gingivalis (p < 0.05), but were not related to hs-CRP levels. No relationship was observed between hs-CRP levels and tertiles as defined by titres of antibody to P. gingivalis strains FDC381 and SU63. CONCLUSIONS Our data indicate that hs-CRP levels were independent of antibody titres to P. gingivalis in Japanese periodontitis patients.

Chronic oral infection with Porphyromonas gingivalis accelerates atheroma formation by shifting the lipid profile. PLoS One 2011; 6:e20240.

Abstract
Background Recent studies have suggested that periodontal disease increases the risk of atherothrombotic disease. Atherosclerosis has been characterized as a chronic inflammatory response to cholesterol deposition in the arteries. Although several studies have suggested that certain periodontopathic bacteria accelerate atherogenesis in apolipoprotein E-deficient mice, the mechanistic link between cholesterol accumulation and periodontal infection-induced inflammation is largely unknown. Methodology/Principal Findings We orally infected C57BL/6 and C57BL/6.KOR-Apoeshl (B6.Apoeshl) mice with Porphyromonas gingivalis, which is a representative periodontopathic bacterium, and evaluated atherogenesis, gene expression in the aorta and liver and systemic inflammatory and lipid profiles in the blood. Furthermore, the effect of lipopolysaccharide (LPS) from P. gingivalis on cholesterol transport and the related gene expression was examined in peritoneal macrophages. Alveolar bone resorption and elevation of systemic inflammatory responses were induced in both strains. Despite early changes in the expression of key genes involved in cholesterol turnover, such as liver X receptor and ATP-binding cassette A1, serum lipid profiles did not change with short-term infection. Long-term infection was associated with a reduction in serum high-density lipoprotein (HDL) cholesterol but not with the development of atherosclerotic lesions in wild-type mice. In B6.Apoeshl mice, long-term infection resulted in the elevation of very low-density lipoprotein (VLDL), LDL and total cholesterols in addition to the reduction of HDL cholesterol. This shift in the lipid profile was concomitant with a significant increase in atherosclerotic lesions. Stimulation with P. gingivalis LPS induced the change of cholesterol transport via targeting the expression of LDL receptor-related genes and resulted in the disturbance of regulatory mechanisms of the cholesterol level in macrophages. Conclusions/Significance Periodontal infection itself does not cause atherosclerosis, but it accelerates it by inducing systemic inflammation and deteriorating lipid metabolism, particularly when underlying hyperlidemia or susceptibility to hyperlipidemia exists, and it may contribute to the development of coronary heart disease.
