Comparison between shear wave elastography and serological findings for the evaluation of fibrosis in chronic liver disease

Prevalence of hepatic steatosis and fibrosis in Turner syndrome: A prospective case-control study

BACKGROUND AND AIMS

Abnormal liver chemistries are common in Turner syndrome (TS). Guidelines suggest that TS patients undergo annual screening of liver enzymes, but the role of non-invasive screening for steatosis and fibrosis is not clearly defined. We compared the prevalence of hepatic steatosis and fibrosis among TS patients to healthy controls using ultrasound with shear-wave elastography (SWE) and assessed for risk factors associated with steatosis and fibrosis in TS.

METHODS

Prospective case-control study of TS versus control patients from 2019 to 2021. All patients underwent abdominal ultrasound with doppler and SWE to assess hepatic fibrosis and steatosis. Risk factors were compared between TS and controls, as well as within the TS group.

RESULTS

A total of 55 TS and 50 control patients were included. Mean age was 23.6 years vs. 24.6 years in the control group (p = .75). TS patients had significantly more steatosis (65% vs. 12%, stage 1 vs. 0, p < .0001) and fibrosis (39% vs. 2%, average Metavir F2 vs. F0, p < .00001) than controls. These findings remained significant after adjusting for body mass index (BMI) (p < .01). GGT is more sensitive than AST or ALT in identifying these changes.

CONCLUSION

TS is associated with an increased prevalence of hepatic steatosis and fibrosis compared to healthy controls. Our findings suggest that serum GGT and ultrasound with SWE may help identify TS patients with liver disease. Early risk factor mitigation including timely oestrogen replacement, weight control, normalization of lipids and promoting multidisciplinary collaboration should be encouraged.

Influence of elevated liver enzyme level on 30-day mortality rates in patients undergoing nonemergency orthopedic surgery

BACKGROUND

The effect of elevated preoperative liver enzyme levels on postoperative outcomes is a topic of concern to clinicians. This study explored the association between elevated preoperative liver enzyme levels and surgical outcomes in patients undergoing orthopedic surgery.

METHODS

Using the American College of Surgeons National Surgical Quality Improvement Program database, we obtained data on adult patients who received nonemergency orthopedic surgery under general anesthesia between 2011 and 2021.

RESULTS

We evaluated the data of 477,524 patients, of whom 6.1% (24 197 patients) had elevated preoperative serum glutamic oxaloacetic transaminase (SGOT) levels. An elevated SGOT level was significantly associated with 30-day postoperative mortality (adjusted hazard ratio, 1.62; 95% confidence interval, 1.39 to 1.90). We determined that the mortality rate rose with SGOT levels. The results remained unchanged after propensity score matching.

CONCLUSION

Elevated preoperative SGOT levels constitute an independent risk factor for 30-day postoperative mortality and are proportionately associated with the risk of 30-day postoperative mortality.
