Clinical Trial Summary

Upper Gastrointestinal bleed is a common presentation in a medical emergency. Patients generally present with hematemesis, melena or in severe cases hematochezia. Incidence and etiology vary from region as well as the level of health care facility. In the US, UGI bleed accountsfor about 300000 admissions per year (6). India has a huge burden of UGI bleed. A study in India showed 4.6% of hospitaladmissions were due to UGI bleed (7). As per the medical record of PGIMER, 2-3 patients of UGIbleed are admitted to the EMOPD every day. Upper GI bleed is anatomically defined as any gastrointestinal bleed originating proximal to ligamentof treitz (8). Causes of UGI bleed are generally divided into variceal and non-variceal in origin. The common etiology of non-variceal bleed are Peptic Ulcer disease (PUD), esophagitis, erosive Gastritis, vascular malformations, Mallory Weiss tear and GI malignancies.Variceal hemorrhage is usually secondary to esophageal varices, but alsocan be due to gastric varices and ectopic varices of the upper GI tract(9).Non-varicealcauses are more common as compared to variceal bleed (10) and among this PUD is the most common (10).But there is recent rising trend of variceal bleed secondary to chronic liver disease and portal hypertension .As per a recently published institutional study, variceal bleed constituted 45.7% of UGI bleed (11). Morbidity and mortality associated with UGI bleed are significantly high.Variceal bleed is becoming a major concern in tertiarycare centers and carries a higher mortality as compared to non variceal bleed(12 ).Clinical severity of UGI bleed may vary from being insignificant to fatal. Mortality from UGI bleed may vary from 2 to 5% where as it around 10-30% in cases of re-bleed (12). Prompt UGI endoscopic procedure is diagnostic as well as therapeutic which should be done ideally within first 24hrsalong with airway, volume and blood resuscitative measures (13).High dose proton pump inhibitors(PPI) are used for non-variceal bleed where as splanchnic vasoconstrictorsare used in variceal bleed along with endoscopic procedure like injection of Epinephrine, Sclerosants, application of haemostatic material like hemoclips/endoclips, over the scope clips, glue or tissue adhesive, haemostatic powder/spray. Beside these endoscopic bipolar electro coagulation, heater probe coagulation, argon plasma coagulator, laser photocoagulation can also be done as and when required. For variceal bleed endoscopic variceal band ligation (EVL) is the main stay of therapy. However routine use of antifibrinolytic agent hasn't been recommended in the guidelines for management of acute UGI bleed. Studies have shown that fibrinolysis may play an important role in GI bleeding dueto premature breakdown of fibrin blood clots at the bleeding site (14). Studies have also shown that many patients with acute UGI bleed have elevated levels of fibrin degradation products (a surrogate marker for fibrinolysis) and that is associated with worse outcomes (14). Fibrinolysisalso contributes to the risk of re-bleed.Literature review suggests that early administration ofTranexamic acid (TXA) reduces mortality due to bleeding in trauma patients (15) and effective in controlling bleeding in menorrhagia (16). Our own institutional study showed that TXA is effective as a bridging therapy in controlling bleeding from haemoptysis before definitive therapeutic intervention done (1). A systematic COCHRANE review of TXA in UGI bleed identified 7 trials (3). These trials showed statistically significant reduction in mortality and reduced need ofsurgical interventions in patients receiving TXA. However the trials had many fallacieslike small sample size, number of biases. The NICE guideline doesn't include TXA inthe management of GI bleed (4). So far studies on use of TXA in UGI bleed haven't been able to either recommend or refute the use of TXA in UGI bleed (3). There is also lack of study form India and the Southeast Asia regarding the efficacy of TXA in UGI bleed. TXA, an anti-fibrinolytic agent, inhibits fibrinolysis by displacing plasminogen from fibrin. So, TXA may have role in bleeding control and preventing re-bleed in acute UGI bleed by stabilization of the clot formation. This study will evaluate the efficacy of early administration of TXA in acute onset UGIbleed, in term of bleeding control, preventing re-bleeding and mortality.

Study Design


Intervention

Drug:
Tranexamic acid
The treatment group will receive Injection TXA 1gm intravenous (IV) over 15 minutes infusion dissolved in 100 ml normal saline (NS- 0.9% NaCl), followed by injection TXA 2 g IV over 12 hours infusion dissolved in a 500 ml NS
Other:
Standard of care
For management, initial priority will be given to secure airway, breathing and circulation. To ensure hemodynamic stability, crystalloids infusion will be given as and when required. Blood transfusion will be initiated at the threshold hemoglobin (Hb) of 7g/dl, to maintain the target Hb of 7-9g/dl or with signs of hemodynamic instability despite fluid resuscitation. Intra venous (IV) PPI and antibiotic will be started promptly in all cases and IV splanchnic vasoconstrictor will be given in all suspicious case of Variceal hemorrhage before definitive therapeutic and diagnostic endoscopic procedure is done.
