Article Abstract
Acute appendicitis (AA) is the first cause of emergency surgery. Leucine-Rich Alpha-2-Glycoprotein 1 (LRG1) has been shown to be a potential biomarker in cases of AA in children, but there are conflicting results for its use in adults. The objective of this study is to compare the median plasma values of LRG1 in patients with acute abdomen with and without appendicitis. This case-control study was conducted prospectively at the emergency room (ER) of a tertiary teaching hospital, between March 1st, 2011 and December 31st, 2012. Patients with recent abdominal pain, aged 18-70 years who attended at the ER were included in the study. Blood samples were drawn at the first presentation. Those who were submitted to surgery and had a pathology report of AA were considered as cases. Those without a need for surgery and treated for other conditions, e.g., pelvic inflammatory disease, were considered as controls. Follow-up in controls was made up to 30 days. LRG1 plasma median values were measured using an ELISA kit and compared between groups. A total of 28 participants, 14 cases with acute appendicitis and 14 controls, were included. The median (range) values of leucine-rich alpha-2-glycoprotein-1 level in the group with appendicitis and control group were 8.8 ng/ml (5.5-31) and 11 (4.6-108) ng/ml, respectively (Mann-Whitney test P = 0.26). Median plasma leucine-rich alpha-2-glycoprotein-1 levels were not useful in diagnosing Acute Appendicitis in patients with acute abdominal pain.

Serum concentrations of leucine-rich alpha-2 glycoprotein 1 (LRG1) are elevated in several cardio-metabolic and inflammatory diseases. LRG1 also plays an important role in the development of hepatic steatosis and insulin resistance. In lipodystrophies (LDs), severe cardio-metabolic complications can be observed.

Aims/hypothesis: Upregulation of serum leucine-rich α-2-glycoprotein 1 (LRG1) has been implicated in diet-induced obesity and metabolic disorders. However, its specific hormonal actions remain unclear. This study aimed to determine whether diet-enhanced serum LRG1 levels promote hyperinsulinaemia by directly stimulating insulin secretion from pancreatic beta cells.

Renal ischemia-reperfusion (I/R) injury leads mainly to acute kidney injury. Leucine-rich alpha-2-glycoprotein 1 (LRG) is upregulated in kidney tissues of mice after renal I/R injury. However, its role in renal I/R injury has not been fully elucidated.

Background: Leucine-rich α-2 glycoprotein 1 (LRG1) is associated with various inflammatory lung diseases. Nevertheless, the connection between LRG1 and adult community-acquired pneumonia (CAP) individuals was still not well understood. Through a prospective cohort study, the correlations of serum LRG1 with severity and prognosis were evaluated in CAP patients.

Article Synopsis
- Therapy failure in metastatic colorectal cancer (mCRC), particularly in the liver, is a significant issue; new strategies are needed as existing HER3-targeting therapies have underperformed in clinical settings.
- Research focused on how liver-derived factors, specifically leucine-rich alpha-2-glycoprotein 1 (LRG1), trigger a non-canonical HER3 activation pathway, facilitating CRC growth independent of traditional HER3 signaling.
- Targeting the LRG1-HER3 interaction may offer novel treatment options for mCRC, showing promise for improving patient outcomes and tackling liver metastases.
