Bacterial infections in patients with liver cirrhosis: clinical characteristics and the role of C-reactive protein

Prevalence and Risk Factors of Post-chemoembolization Syndrome After Chemo-Embolization for Hepatocellular Carcinoma in Thailand

BACKGROUND

The data regarding the incidence of post-embolization syndrome after transarterial chemoembolization for hepatocellular carcinoma in Thailand are scarce. Therefore, this study aimed to determine the prevalence and predictors of post-embolization syndrome after transarterial chemoembolization for hepatocellular carcinoma in Thailand.

METHODS

This retrospective study collected data from patients undergoing transarterial chemoembolization for five years. Post-embolization syndrome was defined as fever and/or abdominal pain, and/or nausea or vomiting that occurred within three days after the transarterial chemoembolization procedure for hepatocellular carcinoma or hospital discharge. Pre-defined predictors for post-embolization syndrome were explored using Poisson regression analysis.

RESULTS

Of the 298 patients and 739 transarterial chemoembolization procedures, the incidence of post-embolization syndrome was 68.1% (203/298) and the incidence density was 53.9% (398/739). Tumor size, Barcelona Clinic Liver Cancer stages, and dose of chemotherapy showed no association with the occurrence of PES. However, a model for end-stage liver disease score was the only predictor for post-embolization syndrome [adjusted IRR 0.91 (0.84-0.98); p = 0.01]. There were three patients developing fever after transarterial chemoembolization due to infection.

CONCLUSION

Post-embolization syndrome was common in patients undergoing transarterial chemoembolization for hepatocellular carcinoma. Patients with a lower model for end-stage liver disease scores were at increased risk of post-embolization syndrome. This study highlights the burden of post-embolization syndrome among patients with hepatocellular carcinoma receiving transarterial chemoembolization.

Platelet-to-White Blood Cell Ratio Is Associated with Adverse Outcomes in Cirrhotic Patients with Acute Deterioration

Background: The platelet-to-white blood cell ratio (PWR) is a hematologic marker of the systemic inflammatory response. Recently, the PWR was revealed to have a role as an independent prognostic factor for mortality in patients with hepatitis B virus (HBV)-related acute-on-chronic failure (ACLF) and HBV-related liver cirrhosis (LC) with acute decompensation (AD). However, the prognostic role of the PWR still needs to be investigated in LC patients with AD. In this study, we analyzed whether the PWR could stratify the risk of adverse outcomes (death or liver transplantation (LT)) in these patients. Methods: A prospective cohort of 1670 patients with AD of liver cirrhosis ((age: 55.2 ± 7.8, male = 1226 (73.4%)) was enrolled and evaluated for 28-day and overall adverse outcomes. Results: During a median follow-up of 8.0 months (range, 1.9−15.5 months), 424 (25.4%) patients had adverse outcomes (death = 377, LT = 47). The most common etiology of LC was alcohol use (69.7%). The adverse outcome rate was higher for patients with a PWR ≤ 12.1 than for those with a PWR > 12.1. A lower PWR level was a prognostic factor for 28-day adverse outcomes (PWR: hazard ratio 1.707, p = 0.034) when adjusted for the etiology of cirrhosis, infection, ACLF, and the MELD score. In the subgroup analysis, the PWR level stratified the risk of 28-day adverse outcomes regardless of the presence of ACLF or the main form of AD but not for those with bacterial infection. Conclusions: A lower PWR level was associated with 28-day adverse outcomes, indicating that the PWR level can be a useful and simple tool for stratifying the risk of 28-day adverse outcomes in LC patients with AD.

High Prevalence of Hormonal Changes and Hepatic Osteodystrophy in Frail Patients with Cirrhosis-An Observational Study

BACKGROUND/AIM

Hormonal changes and hepatic osteodystrophy are less often studied complications of cirrhosis. This study describes the variance in hormones and osteodystrophy between Frail and Not frail patients with cirrhosis.

METHODS

116 outpatients with cirrhosis were prospectively enrolled in this study. Frailty assessment was done using Liver Frailty Index (LFI). Sociodemographic assessment, anthropometry, nutritional assessment, hormone profile, and dual-energy X-ray absorptiometry scan were done in all patients.

RESULTS

116 patients, predominantly males (100 (86.2%) with mean age of 50.16 years (95% CI, 48.43-51.89) were included. Malnutrition was more common in Frail group as compared to Not frail group. Subjective global assessment (SGA) class-B patients were significantly more in Frail group (37 (74%) vs 3 (4.5%), P = 0.001). The prevalence of lower parathyroid hormone (PTH) (14 (28%) vs 2 (3%)), testosterone (33 (66%) vs 15 (22.7%)), vitamin D3 (44 (88%) vs 39 (59.1%)), and cortisol (37 (74%) vs 37 (56.1) levels was higher in Frail group (P < 0.05). The number of patients diagnosed with osteodystrophy (34 (68%) vs 21 (31.8%), P = 0.001) was significantly higher in Frail group. The marker of osteoclastic activity, β-cross laps, was significantly elevated in the Frail group both in males (736 (655-818) vs 380 (329-432), P = 0.001) and (females 619 (479-758) vs 313 (83-543), P = 0.02). Bone mineral density (BMD) at lumbar spine (LS) and neck of femur (NF) had significant correlation with LFI (ρ = 0.60, P = 0.001 for LS and ρ = 0.59, P = 0.001 for NF), serum testosterone (ρ = 0.58, P = 0.001 for LS and ρ = 0.53, P = 0.001 for NF), β-cross laps (ρ = 0.38, P = 0.001for LS and ρ = 0.35, P = 0.000 for NF), vitamin D3 (ρ = 0.23, P = 0.04 for LS and ρ = 0.25, P = 0.01 for NF), PTH (ρ = 0.52, P = 0.001 for LS and ρ = 0.48. P = 0.001 for NF), and cortisol (ρ = 0.50, P = 0.001 for LS and ρ = 0.45, P = 0.001 for NF) levels.

CONCLUSION

This is the first study that highlights the high prevalence of hormonal changes and hepatic osteodystrophy in frail patients with cirrhosis and opens a new dimension for research and target of therapy in this field.

BDNF gene polymorphism and serum level correlate with liver function in patients with hepatitis B-induced cirrhosis

We investigate the correlation of serum brain-derived neurotrophic factor (BDNF) level and its gene polymorphism with liver function classification in patients with hepatitis B virus (HBV) induced liver cirrhosis. A total of 182 patients with HBV induced liver cirrhosis were collected as a case group, and 186 healthy subjects in the same period were used as the control group. ELISA measured serum BDNF levels. Polymerase chain reaction-restriction fragment length polymorphism was used to detect rs6265 (A/G) and rs10835210 (A/C) in the BDNF gene. The serum BDNF level was significantly lower in the case group than in the control group. With the elevation of Child-Pugh classification in patients with HBV induced liver cirrhosis, the decrease trend of serum BDNF level was even lower. The difference in frequency distribution between the case group and the control group was statistically significant regarding GG, GA, and AA genotypes, as well as G and A alleles in rs6265 (all P < 0.05). The frequency distribution of genotypes and alleles of rs6265 was statistically different in HBV induced liver cirrhosis patients with different liver function grades (P < 0.05). In patients with HBV induced liver cirrhosis, the AA genotype of BDNF gene rs6265 had the lowest level of serum BDNF. Our study suggests that serum BDNF plays an important role in the grading and early diagnosis of liver function in patients with HBV-induced liver cirrhosis, and AA genotype at rs6265 of BDNF gene is a negative factor for liver cirrhosis. Moreover, the polymorphism of this locus could affect the serum BDNF level.
