Insights
Coagulation abnormalities are common in chronic liver disease (CLD). Decreased platelet counts and fibrinogen levels, not PT or aPTT, correlate with gastrointestinal bleeding risk in CLD patients.
Area of Science:
- Hepatology
- Hematology
- Gastroenterology
Background:
- Chronic liver disease (CLD) frequently presents with complex coagulation abnormalities.
- Understanding these hemostatic derangements is crucial for managing complications like gastrointestinal (GI) bleeding.
Purpose of the Study:
- To investigate the spectrum of coagulation abnormalities in CLD patients.
- To determine the association between specific clotting test results and the risk of GI bleeding.
Main Methods:
- Adult CLD patients admitted to a tertiary care hospital were enrolled.
- Coagulation parameters including prothrombin time (PT), activated partial thromboplastin time (aPTT), platelet count, and fibrinogen levels were assessed.
- Relative risk (RR) was calculated to evaluate the association between abnormal tests and GI bleeding.
Main Results:
- Profound abnormalities were observed: prolonged PT (88%), elevated aPTT (71%), decreased platelets (37%), and low fibrinogen (15%).
- Decreased platelet counts (RR = 1.96) and fibrinogen levels (RR = 1.47) showed a positive association with GI bleeding.
- Prothrombin time (RR = 1.02) and aPTT (RR = 0.83) did not show a significant relationship with GI bleeding risk.
Conclusions:
- Coagulation derangements are prevalent in CLD patients.
- Reduced platelet counts and fibrinogen levels are linked to an increased risk of GI bleeding.
- While PT and aPTT are not significant predictors of GI bleeding in CLD, they remain valuable prognostic markers.
Objective:
To determine the coagulation abnormalities and relationship between abnormal clotting tests and the risk of gastrointestinal bleeding (GI) among chronic liver disease (CLD) patients admitted at a tertiary care hospital in Pakistan.
Methods:
Adult CLD patients admitted at Liaquat University Hospital Jamshoro, during Nov 2004-Oct 2005, were included in the study. The patients blood were tested for coagulation abnormalities including prothrombin time (PT), activated partial thromboplastin time (aPTT), platelet count and plasma fibrinogen. Association was seen between the abnormal clotting tests and the gastrointestinal bleeding by calculating relative risk (RR) with 95% confidence interval.
Results:
PT was prolonged in 88% and aPTT was raised in 71% cases of CLD. Both PT and aPTT were prolonged in 67% CLD cases. Approximately 37% CLD cases had decreased platelet count and 15% cases had decreased serum fibrinogen level. Relative risk of GI bleeding with abnormal clotting tests in CLD cases were weakly positive for PT (RR = 1.02; 95% CI, 0.49-2.10), negative for aPTT (RR = 0.83; 95% CI, 0.47-1.45), strongly positive for decreased platelet counts (RR = 1.96; 95% CI, 1.08-3.56) and also for decreased fibrinogen level (RR = 1.47; 95% CI, 0.64-3.35).
Conclusion:
Coagulation abnormalities were profound in CLD. Decrease platelet counts and fibrinogen levels were related with GI bleeding but PT and aPTT were not significantly related with GI bleeding in patients with chronic liver disease. Nevertheless, these parameters (PT and aPTT) were still used as prognostic markers.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
