Major complications after ultrasound-guided liver biopsy: An annual audit of a Chinese tertiary-care teaching hospital.

BACKGROUND: As ultrasound-guided percutaneous liver biopsy (PLB) has become a standard and important method in the management of liver disease in our country, a periodical audit of the major complications is needed. AIM: To determine the annual incidence of major complications following ultrasound-guided PLB and to identify variables that are significantly associated with an increased risk of major complications. METHODS: A total of 1857 consecutive cases of PLB were included in our hospital from January 2021 to December 2021. The major complication rate and all-cause 30-d mortality rate were determined. Multivariate analyses were performed by logistic regression to investigate the risk factors associated with major complications and all-cause 30-d mortality following ultrasound-guided PLB. RESULTS: In this audit of 1857 liver biopsies, 10 cases (0.53%) of major complications occurred following ultrasound-guided PLB. The overall all-cause mortality rate at 30 d after PLB was 0.27% (5 cases). Two cases (0.11%) were attributed to major hemorrhage within 7 d after liver biopsy. Fibrinogen less than 2 g/L [odds ratio (OR): 17.226; 95% confidence interval (CI): 2.647-112.102; P = 0.003], post-biopsy hemoglobin level (OR: 0.963; 95%CI: 0.942-0.985; P = 0.001), obstructive jaundice (OR: 6.698; 95%CI: 1.133-39.596; P = 0.036), application of anticoagulants/antiplatelet medications (OR: 24.078; 95%CI: 1.678-345.495; P = 0.019) and age (OR: 1.096; 95%CI: 1.012-1.187; P = 0.025) were statistically associated with the incidence of major complications after PLB. CONCLUSION: In conclusion, the results of this annual audit confirmed that ultrasound-guided PLB can be performed safely, with a major complication rate within the accepted range. Strict patient selection and peri-biopsy laboratory assessment are more important than procedural factors for optimizing the safety outcomes of this procedure.

Body mass index at diagnosis is associated with survival outcome in peripheral T-cell lymphoma: a study of Chinese population.

OBJECTIVE: Obesity increases the risk for many diseases, including some malignancies. We found that in diffuse large B-cell lymphoma, the most common form of non-Hodgkin's lymphoma, patients with higher body mass index had significantly longer overall survival. Patients with peripheral T-cell lymphoma usually have worse outcomes than those with diffuse large B-cell lymphoma. Nonetheless, the association between body mass index at diagnosis and survival in patients with peripheral T-cell lymphoma remains unclear. METHODS: This retrospective study included 411 peripheral T-cell lymphoma patients from January 2010 to July 2017. Patients were stratified by body mass index into low body mass index (<24.0 kg/m2) and high body mass index (≥24.0 kg/m2) groups. We mainly used Cox modelling and the Kaplan-Meier method to evaluate survival and other variables. RESULTS: Multivariate analysis demonstrated that body mass index, international prognostic index and triglyceride level were independent prognostic factors of overall survival. Interestingly, patients with high body mass index had significantly longer overall survival (P < 0.01), with 69% of patients alive at 3 years versus 43% in the low body mass index group. Cox analysis showed reduced mortality in the high body mass index group compared with the low body mass index group (hazard ratio = 0.511, 95% CI, 0.309-0.846, P = 0.009). In addition, patients with high body mass index and low international prognostic index had the longest overall survival (P < 0.001). CONCLUSIONS: High body mass index at the time of diagnosis was associated with improved overall survival in Chinese peripheral T-cell lymphoma patients.

Risk factors of early death in adult patients with secondary hemophagocytic lymphohistiocytosis: a single-institution study of 171 Chinese patients.

Background: Adult secondary hemophagocytic lymphohistiocytosis (HLH) is a potentially life-threatening syndrome characterized by excessive activation of mononuclear-phagocytic system resulting in hyperinflammatory response. To date, the factors influencing early death of HLH are still not fully elucidated. Patients and Methods: We did a retrospective study of 171 adult patients with newly diagnosed HLH at our institution from January 2012 to April 2018. All patients' clinical features, laboratory findings, treatments and prognosis were reviewed. Results: The median age was 49 years (range, 18-88 years), and 110 (64.3%) were male. The major underlying trigger of HLH was malignancy (88/171, 51.5%), especially non-Hodgkin lymphoma. In a multivariate analysis, age ≥54 years (P = 0.002), platelet ≤39.5 × 109/L (P = 0.028), activated partial thromboplastin time (APTT) ≥54 sec (P = 0.048), triglyceride ≥3.23 mmol/L (P < 0.001), lactate dehydrogenase (LDH) ≥1300 U/L (P = 0.012) and malignancy (P = 0.001) were significantly associated with early death in HLH. Then, patients were classified into four groups according to the number of risk factors at the time of diagnosis: low risk (zero, one or two risk factors), low intermediate risk (three risk factors), high intermediate risk (four risk factors) and high risk (at least five risk factors), with the 30-day overall survival (OS) of 92.4%, 58.8%, 30.0% and 4.8%, respectively (P < 0.001). Conclusions: Patients with old age, thrombocytopenia, prolonged APTT, hypertriglyceridemia, elevated LDH and malignancy had inferior survival. It is important to identify those patients at risk of early death, which may guide treatment and reduce mortality.

Blood biomarkers in adults with lymph node enlargement contribute to diagnostic significance of malignancy.

Lymph node enlargement is a common presentation and has a possibility of malignancy like lymphoma that requires early diagnosis. This study aims to analyze the clinical characteristics of these patients and finds out useful predictors of malignant diseases. We retrospectively investigated 81 patients with lymph node enlargement between July 2, 2014 and May 17, 2016. The characteristics and laboratory findings were evaluated combining with the final diagnosis. The diagnoses were malignancy in 51 patients and benign lymphadenopathy in 30 patients. Increased beta2-microglobulin (B2M) (P = 0.012) was found to be associated with malignant diseases, and level of 3699.5 µg/L was used as a cut-off value to differentiate the malignancies from benign diseases, offering 63.4% sensitivity and 87.0% specificity. Immunoglobulin G (IgG) (P = 0.038) levels were significantly lower in malignant group, whose receiver operating characteristic curve showed that level of 1121.5 mg/dl had sensitivity and specificity as 58.5% and 82.6%. Moreover, through analysis of cytokines, we found interleukin-10 (IL-10) levels were elevated in malignant group compared with benign group. Serum B2M and IgG levels were concluded to be useful parameters for predicting malignancies. Besides, increased IL-10 levels indicated a higher risk of malignancy in some way.

Prognostic evaluation of high sensitivity-C reactive protein in peripheral T-cell lymphoma / 中国肿瘤临床

Objective:To investigate the prognostic significance of high sensitivity-C reactive protein (Hs-CRP) in patients with peripher-al T-cell lymphoma (PTCL). Methods:A total of 234 newly diagnosed PTCL patients with a median age of 48 years were analyzed retro-spectively. Serum Hs-CRP levels and other factors, including tumor stage and international prognostic index (IPI), were determined. Af-ter a median follow-up of 23 months, the relationship between Hs-CRP and overall survival (OS) was observed. Results:Serum Hs-CRP level positively correlated with IPI score (r=0.132, P<0.001), tumor stage (r=0.183, P=0.005), B symptoms (r=0.225, P=0.001), and lactic dehydrogenase (r=0.169, P=0.009), but negatively correlated with plasma albumin levels (r=?0.343, P<0.001), hemoglobin concentra-tion (r=?0.239, P<0.001), and platelet count (r=0.131, P=0.045), and is uncorrelated with age (P>0.05), gender (P>0.05), fitness score (P>0.05), and leukocyte count (P>0.05). Patients with serum Hs-CRP levels≤10 mg/L had better OS than patients with serum Hs-CRP levels>10 mg/L. Univariate and multivariate Cox regression models showed that platelet count, Hs-CRP, albumin levels, and IPI score were independent adverse prognostic factors. Conclusion:The baseline Hs-CRP level can serve as a major indicator of prognosis in PT-CL patients.
