The inverse association of incident cardiovascular disease with plasma bilirubin is unaffected by adiponectin

Objective

Bilirubin may protect against atherosclerotic cardiovascular disease (CVD). The heme oxygenase pathway is crucial for bilirubin generation, and is stimulated by adiponectin. We tested the relationship of plasma bilirubin with adiponectin, and determined whether the association of incident CVD with bilirubin is modified by adiponectin.

Methods

A community-based prospective nested case–control study (PREVEND cohort) was carried out in 87 non-diabetic men who developed a first cardiovascular event (cases) and 94 controls during a median follow-up of 6.1 (2.8–10.6) years.

Results

In all subjects combined, bilirubin was positively related to adiponectin (r = 0.205, P = 0.006). Age-adjusted incident CVD was inversely associated with bilirubin (hazard ratio (HR): 0.80 (95% CI 0.65–0.99), P = 0.048), independently of adiponectin (HR: 0.78 (95% CI 0.63–0.97), P = 0.027). Adiponectin did not modify the association of CVD with bilirubin (interaction term: P = 0.65). After additional adjustment for CVD risk factors, neither the association of incident CVD with bilirubin nor with adiponectin remained significant (P > 0.20 for both), and there was again no interaction between bilirubin and adiponectin on CVD risk (P = 0.67).

Conclusion

Bilirubin is related to adiponectin, but the association of bilirubin with CVD risk is largely unaffected by adiponectin.     

严重高胆红素血症新生儿急性胆红素脑病危险因素分析

目的 探讨严重高胆红素血症新生儿急性胆红素脑病（ABE）发生的危险因素。方法选择本院2010年1月至2012年12月诊治的胎龄≥35周、血清胆红素（TSB）峰值〉425μmol/L且资料完整、进行了头颅核磁共振及脑干听觉诱发电位检查的患儿,根据是否符合ABE的诊断标准分为病例组和对照组,对一般资料、母孕期情况、合并症、围生期缺氧、黄疸的发生发展过程及实验室指标共22项临床因素进行单因素分析,对其中13项进行多因素Logistic回归分析。结果病例组43例,对照组30例,单因素分析显示,病例组出生后体重下降程度、TSB峰值、平均每日胆红素上升值及B/A值均高于对照组,差异有统计学意义（P〈0.05）;多因素分析提示,严重黄疸诊断日龄、围生期缺氧史及酸中毒与ABE的发生相关,OR（95%可信区间）分别为0.545（0.413~0.962）、36.589（1.114~1202.032）、7.963（1.294~49.010）,P均〈0.05。结论 在严重高胆红素血症新生儿中,严重黄疸诊断日龄越小,曾有围生期缺氧史和（或）伴有酸中毒者,ABE发生风险越高;而母乳喂养、出生后体重下降多、存在母子血型不合溶血、葡萄糖-6-磷酸脱氢酶缺陷则可能是严重高胆红素血症的原因。加强黄疸的监测、对严重高胆红素血症患儿积极纠正酸中毒,可能有助于预防胆红素脑病。

Liver dysfunction as a cytokine storm manifestation and prognostic factor for severe COVID-19

Liver damage in severe acute respiratory coronavirus 2 infection occurs in patients with or without preexisting liver disorders, posing a significant complication and mortality risk. During coronavirus disease 2019 (COVID-19), abnormal liver function is typically observed. However, liver injury may occur because of the treatment as well. Ischemia, cytokine storm, and hypoxia were identified as the three major factors contributing to liver damage during COVID-19. Indeed, raised liver enzymes during hospitalizations may be attributed to medications used, as well as sepsis and shock. As a result, the proportion of hospitalized patients afflicted with COVID-19 and pathological liver biomarkers varies from 14% to 53%. Aminotransferases and bilirubin are found most often elevated. Usually, increased gamma-glutamyltransferase, alkaline phosphatase, and decreased serum albumin levels are demonstrated. Additionally, although there is no specific treatment for COVID-19, many of the drugs used to treat the infection are hepatotoxic. In this mini-review, we focus on how liver dysfunction can be one of the features associated with the COVID-19 cytokine storm. Furthermore, data show that liver injury can be an independent predictor of severe COVID-19, the need for hospitalization, and death.
