RESUMO

Background and Objectives: Transarterial chemoembolization (TACE) is a widely accepted treatment for hepatocellular carcinoma (HCC). Regarding TACE, arterial injuries, such as hepatic artery spasm or dissection, can also occur, although pseudoaneurysms are rare. We report a case of pseudoaneurysm following TACE. Materials and Methods: A 78-year-old man had been undergoing TACE for HCC in segment 8 of the liver for the past 5 years, with the most recent TACE procedure performed approximately 1 month prior. He presented to the emergency department with melena that persisted for 5 days. Computed tomography revealed a pseudoaneurysm in the S8 hepatic artery with hemobilia. Results: the pseudoaneurysm was successfully treated by N-Butyl-cyanoacrylate glue embolization. Conclusions: In patients that have undergone TACE presenting with melena and hemobilia identified on CT, consideration of hepatic artery pseudoaneurysm is crucial. Such cases can be safely and effectively treated with endovascular managements.

RESUMO

To address the challenge of solid tumor targeting in CAR-T therapy, we utilized the A56 antigen, which is uniquely expressed on a diverse range of cancer cells following the systemic administration of an oncolytic vaccinia virus (OVV). Immunohistochemical assays precisely confirmed exclusive localization of A56 to tumor tissues. In vitro studies demonstrated a distinct superiority of A56-dependent CAR-T cytotoxicity across multiple cancer cell lines. Building on these in vitro observations, we strategically administered A56 CAR-T cells, OVV, and hydroxyurea (HU) combination in HCT-116 tumor-bearing non-obese diabetic/severe combined immunodeficiency (NOD/SCID) mice, leading to a significant reduction in tumor size and an extended time to progression. Consequently, A56-targeting combinatorial immunotherapy provides the benefit of reducing inadvertent CAR-T effects on normal cells while preserving its effectiveness against cancer cells. Furthermore, our approach of implanting A56 via OVV on tumors facilitates a wide therapeutic application of CAR-T cells across various solid tumors.

RESUMO

BACKGROUND: The impact of tumor-infiltrating neutrophils (TINs) on clinical outcomes has been reported in various cancer types, but their role in hepatocellular carcinoma (HCC) has not been fully evaluated. The aim of this study was to investigate the prognostic values for TINs in HCC patients undergoing curative resection. METHODS: We assessed immune markers (CD3, CD4, CD8, CD66b) using immunohistochemistry in 115 patients who underwent curative resection for HCC. We analyzed the prognostic values for tumor-infiltrating immune cells, including neutrophils, and other clinicopathological factors. RESULTS: In the Multivariate Cox analysis of overall survival (OS), alpha-fetoprotein (AFP) ≥ 100 ng/mL (hazard ratio (HR), 2.74, 95% confidence interval (CI), 1.17-6.44; P = 0.021) and Barcelona Clinic Liver Cancer (BCLC) B/C stage (HR, 3.98, 95% CI, 1.68-9.43; P = 0.020) were found to be independent poor prognostic factors in HCC patients undergoing resection. The presence of CD66b+TINs was observed in 66 (57.4%) patients. However, CD66b+TINs were not associated with recurrence-free survival and OS. CONCLUSIONS: Our study identified low CD66b+TINs in resectable HCC, and CD66b+ TINs did not have a significant role for the clinical outcomes of patients undergoing curative resection. The results suggest that TINs may play a role in more advanced stages of HCC.

RESUMO

BACKGROUND: Life-threatening bleeding following endoscopic variceal ligation (EVL) in patients with cirrhosis rarely can occur. The present study aimed to evaluate the performance of computed tomography (CT) in predicting the risk of early bleeding following EVL in cirrhotic patients. METHODS: We retrospectively investigated 285 cirrhotic patients who had undergone EVL. EVL was performed for prophylaxis or acute variceal bleeding. The patients were classified into 2 groups: early bleeding (< 14 days after EVL) and non-early bleeding. We compared baseline characteristics including CT findings between the patient groups. RESULTS: Among the 285 patients who underwent EVL treatment, 19 patients (6.7%) experienced early bleeding. On average, these bleeding occurred 9.3 ± 3.5 days after the EVL, with a range of 3 to 13 days. Patients who experience early bleeding had a higher six-week bleeding-related mortality rate compared to those in the non-early bleeding group (31.6% vs. 10.2%; p = 0.014). There was a correlation between the grade of esophageal varix observed during endoscopy and the diameter of esophageal varix observed on CT (p < 0.001). The diameter of esophageal varix on CT was identified as the only significant predictive factor for early bleeding (p = 0.005). CONCLUSION: A larger esophageal varix diameter observed on CT is associated with an increased risk of early bleeding after EVL treatment. Early identification of this high-risk group can provide a change of treatment strategies to improve patient outcomes.

RESUMO

Background: The use of Adriamycin (ADR), also known as doxorubicin, as a chemotherapy agent is limited by its detrimental adverse effects, especially cardiotoxicity. Recent studies have emphasized the crucial role of angiotensin II (Ang-II) in the development of ADR-induced cardiomyopathy. This study aimed to explore the potential cardioprotective effects of losartan in a rat model of ADR-induced cardiomyopathy. Methods: Male Sprague-Dawley rats were randomly divided into 3 groups: a control group (group C), an ADR-treated group (ADR 5 mg/kg/wk for 3 weeks via intraperitoneal injections; group A), and co-treatment of ADR with losartan group (same dose of ADR and losartan; 10 mg/kg/day per oral for 3 weeks; group L). Western blot analysis was conducted to demonstrate changes in brain natriuretic peptide, collagen 1, tumor necrosis factor (TNF)-α, interleukin-6, matrix metalloproteinase (MMP)-2, B-cell leukemia/lymphoma (Bcl)-2, Bcl-2-associated X (Bax), and caspase-3 protein expression levels in left ventricular (LV) tissues from each group. Results: Losartan administration reduced LV hypertrophy, collagen content, and the expression of pro-inflammatory factors TNF-α and MMP-2 in LV tissue. In addition, losartan led to a decrease in the expression of the pro-apoptotic proteins Bax and caspase-3 and an increase in the expression of the anti-apoptotic protein Bcl-2. Moreover, losartan treatment induced a reduction in the apoptotic area compared to group A. Conclusion: In an ADR-induced cardiomyopathy rat model, co-administration of ADR with losartan presented cardioprotective effects by attenuating LV hypertrophy, pro-inflammatory factors, and apoptosis in LV tissue.

RESUMO

PURPOSE: To evaluate the incidence, risk factors, and prognosis associated with peritoneal seeding after percutaneous radiofrequency ablation (RFA) for HCC, focusing on viable tumors after previous locoregional treatment, including TACE and RFA. METHODS: Exactly 290 patients (mean age, 67.9 years ± 9.74; 223 men) with 383 HCCs (mean size, 15.9 mm ± 5.49) who underwent RFA between June 2012 and December 2019 were included in this retrospective study. Among them, 158 had history of previous treatment (mean number, 1.3 ± 1.8) with 109 viable HCCs. Cumulative seeding after RFA was estimated using the Kaplan-Meier method. Independent factors affecting seeding were investigated using multivariable Cox proportional hazards regression analysis. RESULTS: Median follow-up was 1175 days (range: 28-4116). Seeding incidence was 4.1 (12/290) and 4.7% (17/383) per patient and tumor, respectively. The median time interval between RFA and detection of seeding was 785 days (range: 81-1961). Independent risk factors for seeding included subcapsular tumor location (hazard ratio [HR] 4.2; 95% confidence interval [CI] 1.4, 13.0; p = 0.012) and RFA for viable HCC after previous locoregional treatment (HR 4.5; 95% CI 1.7, 12.3; p = 0.003). Subgroup analysis for viable tumors, revealed no significant difference in cumulative seeding rates between the TACE and RFA groups (p = 0.078). Cumulative overall survival rates differed significantly between patients with and without seeding metastases (p < 0.001). CONCLUSION: Peritoneal seeding after RFA is a rare, delayed complication. Subcapsular-located and viable HCC after previous locoregional treatment are potential risk factors for seeding. Seeding metastases could affect the prognosis of patients who cannot receive local therapy.

RESUMO

In the natural course of chronic hepatitis B, the immune tolerance phase is characterized by HBeAg positivity, very high levels of HBV DNA, and persistent normal alanine aminotransferase. The international guideline recommendation for patients in this phase is observation without antiviral treatment because of the low risk of disease progression and the lack of effective antiviral agents. However, recent retrospective studies have shown that progression to hepatic fibrosis and hepatocellular carcinoma may occur in patients who are in the immune tolerance phase. Despite the conceptual definition and clinical diagnostic criteria for this phase, it is difficult to accurately diagnose the true immune tolerance phase. Therefore, we should pay attention to the clinical evaluation and interpretation of the immune tolerance phase and understand the clinical situations in which antiviral treatments should be considered.

RESUMO

RATIONALE: Most gastric varices at the fundus drain into the left renal vein via the gastrorenal shunt (80-85% of cases) or the inferior vena cava via the gastrocaval shunt (10-15%). Therefore, plug-assisted retrograde transvenous obliteration (PARTO) is usually performed via a gastrorenal shunt. Here, we report a case of gastric varix treated with PARTO via a gastrocaval shunt. PATIENT CONCERNS: A 46-year-old woman with hepatitis B virus and liver cirrhosis visited the emergency room in our hospital with the main symptom of hematemesis and hematochezia. DIAGNOSES: Endoscopy and computed tomography (CT) revealed a gastric varix and thrombotic-occluded transjugular intrahepatic portosystemic shunt (TIPS) stent. INTERVENTIONS: The patient underwent PARTO via a gastrocaval shunt to manage gastric variceal bleeding after failed TIPS revision. OUTCOMES: On CT, the gastric varix completely disappeared. The patient did not experience any additional bleeding events. LESSONS: PARTO via a gastrocaval shunt is safe and effective.

RESUMO

BACKGROUND: Regorafenib has shown promising results as a second-line therapy for patients with hepatocellular carcinoma (HCC) who progressed on sorafenib. Although there have been several data regarding the efficacy of sequential therapy with sorafenib and that of regorafenib in real-life, specific inflammation markers for predicting the prognosis have not been studied. This study aimed to investigate prognostic value of systemic inflammatory markers in patients with HCC who received sorafenib-regorafenib sequential therapy. METHODS: We retrospectively analyzed medical data of patients who received regorafenib for the treatment of HCC after sorafenib failure. Progression free survival (PFS) and overall survival (OS) were assessed using the Kaplan-Meier survival curves. Univariate and multivariate analyses were performed to analyze the factors associated with survival. RESULTS: A total of 58 patients who received at least one dose of regroafenib and fulfilled the eligibility criteria, good performance status (Eastern Cooperative Oncology Group [ECOG] 0-1) and preserved liver function (Child-Pugh-A), were included in the analysis. The median PFS was 3 months (95% confidence interval [CI] = 0.981-5.019) and the median OS was 8 months (95% CI = 5.761-10.239). Elevated systemic immune-inflammation index (SII ≥340) was independently associated with poor OS. In multivariate analysis, the SII (hazard ratio [HR] = 2.211, 95% CI = 1.089-4.489, P = 0.028) and alpha-fetoprotein (AFP) (HR = 2.750, 95% CI = 1.259-6.010, P = 0.011) were independent predictors of OS. CONCLUSION: Elevated SII is associated with poor OS in patients with HCC who received sequential therapy with sorafenib and regorafenib. In addition, when selecting a treatment strategy, the SII can be used in combination with the AFP level as a promising prognostic tool for HCC.

RESUMO

PURPOSE: Alpha-fetoprotein (AFP) is a prognostic marker for hepatocellular carcinoma (HCC). We investigated the prognostic value of AFP levels in patients who achieved complete response (CR) to transarterial chemoembolization (TACE) for HCC. MATERIALS AND METHODS: Between 2005 and 2018, 890 patients with HCC who achieved a CR to TACE were recruited. An AFP responder was defined as a patient who showed elevated levels of AFP (>10 ng/mL) during TACE, but showed normalization or a >50% reduction in AFP levels after achieving a CR. RESULTS: Among the recruited patients, 569 (63.9%) with naïve HCC and 321 (36.1%) with recurrent HCC after complete resection were treated. Before TACE, 305 (34.3%) patients had multiple tumors, 219 (24.6%) had a maximal tumor size >3 cm, and 22 (2.5%) had portal vein tumor thrombosis. The median AFP level after achieving a CR was 6.36 ng/mL. After a CR, 473 (53.1%) patients experienced recurrence, and 417 (46.9%) died [median progression-free survival (PFS) and overall survival (OS) of 16.3 and 62.8 months, respectively]. High AFP levels at CR (>20 ng/mL) were independently associated with a shorter PFS [hazard ratio (HR)=1.403] and OS (HR=1.284), together with tumor multiplicity at TACE (HR=1.518 and 1.666, respectively). AFP non-responders at CR (76.2%, n=359 of 471) showed a shorter PFS (median 10.5 months vs. 15.5 months, HR=1.375) and OS (median 41.4 months vs. 61.8 months, HR=1.424) than AFP responders (all p=0.001). CONCLUSION: High AFP levels and AFP non-responders were independently associated with poor outcomes after TACE. AFP holds clinical implications for detailed risk stratification upon achieving a CR after TACE.

RESUMO

Background/Aims: Glecaprevir/pibrentasvir (G/P) is a combination of direct-acting antiviral agents that is an approved treatment for chronic infections by all six hepatitis C virus (HCV) genotypes. However, there are limited data on the effect of G/P in Korean patients in actual real-world settings. We evaluated the real-life effectiveness and safety of G/P at a single institution in Korea. Methods: This retrospective, observational, cohort study used sustained virologic response at 12 weeks after treatment completion (SVR12) as the primary effectiveness endpoint. Safety and tolerability were also determined. Results: We examined 267 individuals who received G/P for chronic HCV infections. There were 148 females (55.4%), and the overall median age was 63.0 years (range, 25 to 87 years). Eighty-three patients (31.1%) had HCV genotype-1 and 182 (68.2%) had HCV-2. A total of 212 patients (79.4%) were HCV treatment-naïve, 200 (74.9%) received the 8-week treatment, 13 (4.9%) had received prior treatment for hepatocellular carcinoma, 37 (13.7%) had chronic kidney disease stage 3 or higher, and 10 (3.7%) were receiving dialysis. Intention to treat (ITT) analysis indicated that 256 (95.9%) achieved SVR12. A modified ITT analysis indicated that SVR12 was 97.7% (256/262). Six patients failed therapy because of posttreatment relapse. SVR12 was significantly lower in those who received prior sofosbuvir treatment (p=0.002) and those with detectable HCV RNA at week 4 (p=0.027). Seventy patients (26.2%) experienced one or more adverse events, and most of them were mild. Conclusions: These real-life data indicated that G/P treatment was highly effective and well tolerated, regardless of viral genotype or patient comorbidities.

RESUMO

BACKGROUND AND AIMS: The influence of direct-acting antivirals (DAAs) on chronic hepatitis C (CHC)-related hepatocellular carcinoma (HCC) remains controversial. We investigated the effect of eradicating CHC using DAAs on treatment outcomes in patients with CHC-related HCC treated with transarterial chemoembolization (TACE). METHODS: This nationwide, multi-center, retrospective study recruited patients with CHC-related HCC treated with TACE as the first-line anti-cancer treatment, and who achieved a sustained virological response (SVR) using DAAs (DAA group) between 2006 and 2017. Patients achieving an SVR following interferon-based treatment (IFN group) and those without treatment (control group) were also recruited for comparison. RESULTS: A total of 425 patients were eligible for the study. Of these, 356 (83.8%), 26 (6.1%), and 43 (10.1%) were allocated to the control, IFN, and DAA groups, respectively. A multivariate analysis showed that liver cirrhosis, segmental portal vein thrombosis, and larger maximal tumor size independently predicted an increased risk of progression (all p < 0.05), whereas, the DAA group (vs. IFN and control groups) independently predicted a reduced risk of progression (hazard ratio (HR) = 0.630, 95% confidence interval 0.411-0.966, p = 0.034). The cumulative incidence rate of HCC progression in the DAA group was significantly lower than that in the IFN and control groups (p = 0.033, log-rank test). In addition, the DAA group (vs. IFN and control groups) was independently associated with a reduced risk of mortality (p = 0.042). CONCLUSIONS: DAA treatment provided significantly prolonged progression-free survival in patients with CHC-related HCC treated with TACE compared to that in patients administered IFN or no treatment.

RESUMO

Viral replication of thymidine kinase deleted (tk-) vaccinia virus (VV) is attenuated in resting normal cells, enabling cancer selectivity, however, replication potency of VV-tk- appears to be diminished in cancer cells. Previously, we found that wild-type herpes simplex virus (HSV)-tk (HSV-tk) disappeared in most of the recombinant VV after multiple screenings, and only a few recombinant VV containing naturally mutated HSV-tk remained stable. In this study, VV-tk of western reserve (WR) VV was replaced by A167Y mutated HSV-tk (HSV-tk418m), to alter nucleoside selectivity from broad spectrum to purine exclusive selectivity. WOTS-418 remained stable after numerous passages. WOTS-418 replication was significantly attenuated in normal cells, but cytotoxicity was almost similar to that of wild type WR VV in cancer cells. WOTS-418 showed no lethality following a 5 × 108 PFU intranasal injection, contrasting WR VV, which showed 100% lethality at 1 × 105 PFU. Additionally, ganciclovir (GCV) but not BvdU inhibited WOTS-418 replication, confirming specificity to purine nucleoside analogs. The potency of WOTS-418 replication inhibition by GCV was > 10-fold higher than that of our previous truncated HSV-tk recombinant OTS-412. Overall, WOTS-418 demonstrated robust oncolytic efficacy and pharmacological safety which may delegate it as a candidate for future clinical use in OV therapy.

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) is an inflammation-related cancer, where nonresolving inflammation contributes to its development and progression. Peripheral inflammatory cells have been shown to be associated with the prognosis of various types of cancer. The present study investigated the utility of pretreatment peripheral inflammatory cells in the prognosis of patients with HCC. METHODS: We retrospectively analyzed data regarding peripheral inflammatory cell, and patient and tumor characteristics from patients with HCC who were diagnosed between November 2008 and March 2018. Baseline data, including peripheral inflammatory cell counts, were recorded before treatment. The relationships between overall survival (OS) and study variables were assessed. RESULTS: A total of 1681 patients who were diagnosed with HCC were included. In univariate and multivariate analyses, individual neutrophil, lymphocyte and monocyte cell counts were found as independent indicators of poor OS. High neutrophil (≥3100 × 106/L) and, monocyte (≥470 × 106/L) counts and low lymphocyte counts (< 1640 × 106/L) significantly associated with reduced OS (p < 0.05). Neutrophil and, monocyte cell counts rose and lymphocyte counts decreased in association with advancing the Barcelona Clinic Liver Cancer stage (P < 0.001). CONCLUSIONS: Pretreatment peripheral neutrophils, lymphocytes, and monocytes are independently associated with outcomes of patients with HCC. These cells provides a noninvasive, low-cost, easy, and reproducible biomarker that can be used in routine clinical practice to predict the prognosis of patients with HCC.

RESUMO

Background: The Milan criteria (MC) used to select patients for liver transplantation among patients with hepatocellular carcinoma (HCC) do not include tumor biology. Furthermore, systemic inflammatory markers have been identified to predict tumor biology. The present study investigated prognostic value of systemic inflammatory markers, including neutrophil count, in predicting the prognosis of patients with HCC undergoing living donor liver transplantation (LDLT). Methods: We retrospectively analyzed data regarding peripheral blood inflammatory markers, as well as patient and tumor characteristics of patients with HCC who underwent LDLT. Univariate and multivariate analyses were performed to analyze variables associated with survival. Results: A total of 103 patients with HCC who underwent LDLT were included. The 3- and 5-year recurrence-free survival (RFS) in patients with a high neutrophil count (>2,640/µL) were significantly lower than those in patients with a low neutrophil count (≤2,640/µL; 70.0% and 64.7% vs. 88.3% and 84.6%, respectively; P=0.02). Patients with a high neutrophil count also had lower 5-year overall survival (OS; 63.9% vs. 79.3%, P=0.03). In multivariate analysis, radiologic MC (hazard ratio [HR], 5.04; P=0.02) and neutrophil count (HR, 4.47; P=0.04) were independent factors predicting RFS. Among patients exceeding the MC, those with a high neutrophil count had significantly lower 5-year RFS than those with low neutrophil count (10% vs. 83%; P<0.01). Conclusions: We demonstrated that high preoperative neutrophil count is associated with poor RFS and OS in patients with HCC undergoing LDLT.

RESUMO

Kawasaki disease (KD) is a systemic vasculitis affecting infants and children; it manifests as fever and signs of mucocutaneous inflammation. Intravenous immunoglobulin (IVIG) treatment effectively attenuates the fever and systemic inflammation. However, 10-20% patients are unresponsive to IVIG. To identify genetic variants influencing IVIG non-response in KD, a genome-wide association study (GWAS) and a replication study were performed using a total of 148 IVIG non-responders and 845 IVIG-responders in a Korean population. rs28662 in the sterile alpha motif domain-containing protein 9-like (SAMD9L) locus showed the most significant result in the joint analysis of GWAS and replication samples (odds ratio (OR) = 3.47, P = 1.39 × 10-5). The same SNP in the SAMD9L locus was tested in the Japanese population, and it revealed a more significant association in a meta-analysis with Japanese data (OR = 4.30, P = 5.30 × 10-6). These results provide new insights into the mechanism of IVIG response in KD.

RESUMO

BACKGROUND AND AIMS: All published meta-analyses failed to demonstrate that preoperative transarterial chemoembolization improves the clinical outcomes of patients with resectable hepatocellular carcinoma. The present study aimed to investigate the utility of systemic inflammatory cells as a tumor biology marker predicting therapeutic benefit of neoadjuvant transarterial chemoembolization in patients with resectable hepatocellular carcinoma. MATERIALS AND METHODS: We retrospectively investigated 441 hepatocellular carcinoma patients who underwent curative resection. Among 441 patients, 73 patients underwent preoperative transarterial chemoembolization, and 368 patients did not. We compared recurrence-free survival and overall survival between transarterial chemoembolization plus sequential resection group and resection only group. We analyzed whether pretreatment neutrophil-lymphocyte ratio demonstrates survival benefit in each groups. RESULTS: No significant difference was observed in recurrence-free or overall survival between both groups. In the transarterial chemoembolization plus sequential resection group, the 5-year overall survival in patients with high neutrophil-lymphocyte ratio (≥1.6) was significantly lower than that in patients with low neutrophil-lymphocyte ratio (78.4% and 100%, P = 0.027). High neutrophil-lymphocyte ratio was associated with vascular invasion (P = 0.033). CONCLUSION: Neutrophil-lymphocyte ratio can be considered as a predictive factor of long-term survival and used to identify patients with resectable hepatocellular carcinoma who benefit from neoadjuvant transarterial chemoembolization.

RESUMO

BACKGROUND AND AIM: Although sorafenib is the first systemic therapy to show survival benefit for advanced hepatocellular carcinoma (HCC), its survival benefit is variable for HCC. Systemic inflammation may be associated with survival in HCC. We investigated the use of systemic inflammation markers, including neutrophil-to-lymphocyte ratio (NLR), in the prognosis of sorafenib-treated HCC patients. PATIENTS AND METHODS: We retrospectively analyzed data of 82 patients with advanced HCC who received sorafenib as the first-line treatment. Data on pretreatment and post-treatment (2-3 months after initiating sorafenib therapy, first tumor response evaluation day) clinical, laboratory, and tumor characteristics were collected. Survival-related prognostic factors were analyzed. RESULTS: Patients were mostly in the intermediate (12.2%) or advanced (87.8%) Barcelona Clinic Liver Cancer stages. Fifty-six (68.3%) patients had vascular invasion and 34 (41.5%) patients had extrahepatic disease. The median progression-free survival (PFS) and overall survival (OS) were 4.7 months [95% confidence interval (CI): 2.8-6.5 months] and 4.7 months (95% CI: 2.8-6.5 months). In multivariate analysis for OS, diarrhea (hazard ratio: 0.588; 95% CI: 0.348-0.993) and NLR decline (decreased compared with pretreatment) (hazard ratio: 0.479; 95% CI: 0.300-0.765) were independent factors of good OS. In the NLR decline group, the median PFS and OS were 7.1 and 7.3 months, respectively. In the NLR nondecline group, the median PFS and OS were 3.0 and 3.2 months, respectively. The difference in OS between the two groups was significant (P = 0.004). CONCLUSION: A change in NLR after sorafenib therapy was associated with a better prognosis in patients with advanced HCC.

RESUMO

Pediatric blood pressure (BP) reference tables are generally based on sex, age, and height and tend to be cumbersome to use in routine clinical practice. In this study, we aimed to develop a new, height-specific simple BP table according to the international child BP reference table based on sex, age and height and to evaluate its performance using international data. We validated the simple table in a derivation cohort that included 58,899 children and adolescents aged 6-17 years from surveys in 7 countries (China, India, Iran, Korea, Poland, Tunisia, and the United States) and in a validation cohort that included 70,072 participants from three other surveys (China, Poland and Seychelles). The BP cutoff values for the simple table were calculated for eight height categories for both the 90th ("elevated BP") and 95th ("high BP") percentiles of BP. The simple table had a high performance to predict high BP compared to the reference table, with high values (boys/girls) of area under the curve (0.94/0.91), sensitivity (88.5%/82.9%), specificity (99.3%/99.7%), positive predictive values (93.9%/97.3%), and negative predictive values (98.5%/97.8%) in the pooled data from 10 studies. The simple table performed similarly well for predicting elevated BP. A simple table based on height only predicts elevated BP and high BP in children and adolescents nearly as well as the international table based on sex, age, and height. This has important implications for simplifying the detection of pediatric high BP in clinical practice.
