Platelet count can predict the grade of esophageal varices in cirrhotic patients: a cross-sectional study.

Background: Bleeding from esophageal varices is a life-threatening complication in cirrhosis. Screening endoscopy is recommended in cirrhotic patients to identify patients at risk of variceal hemorrhage, but this is an invasive procedure and has limitations. Therefore, thrombocytopenia has been proposed to predict the existence and grade of esophageal varices. The aim of the current study was to determine a correlation between platelet count and grades of esophageal varices in patients with liver cirrhosis. Methods: This cross-sectional study was conducted at the POF Hospital, Wah Cantt from 1 st October, 2017 to 30 th May, 2018. Newly diagnosed cases of cirrhosis having varices of any grade on endoscopy were included. Endoscopic findings of patients were standardized using Paquet grading system. On the basis of platelet count, patients were divided into four subgroups. Platelet count groups were correlated with grading of esophageal varices using Spearman rank correlations. Chi Square test was used to see association between the platelet count and grade of esophageal varices. Results: 110 patients were included in the study, 55.5% (n=61) were male. Mean age of the patients was 59.89±9.01 years. Platelet count was <50,000/uL in 35.5% patients, 50,000-99,000/uL in 26.4%, 100,000-150000 in 12.7%, and >150,000/uL in 25.5% patients. Grade I esophageal varices were found in 23.6% of patients, whereas grade II, III and IV were found in 24.5%, 33.6% and 18.2% of patients, respectively. Mean platelet count was 213884.62/mm 3 in patients with grade I varices, whereas it was 119518.52/mm 3, 58386.49/mm 3 and 21600.00/mm 3 in patients with grade II, III and IV varices, respectively (p=<0.0001). A significant negative correlation between platelet count and grades of esophageal varices was found (p<0.001). Conclusion: Platelet count can predict the grade of esophageal varices in cirrhotic patients. There is significant negative correlation between platelet count and grades of esophageal varices.

Oral Erythromycin Improves the Quality of Endoscopy in Upper Gastrointestinal Bleeding Patients.

Background Upper gastrointestinal bleeding is a life-threatening emergency. Endoscopy is the therapeutic and diagnostic procedure of choice after initial stabilization of the patient. But the presence of retained blood, blood products, and other residual material in the stomach is a big challenge for endoscopists during urgent endoscopy after acute upper gastrointestinal bleeding. Intravenous erythromycin before endoscopy improves the visualization of gastric and duodenal mucosa in these patients. Use of oral erythromycin is more easy and convenient, so the objective of our study was to assess the effects of oral erythromycin on quality of endoscopy in upper gastrointestinal bleeding patients. Methods This interventional study was conducted at the Department of Medicine, POF Hospital Wah Cantt, Pakistan from January 2019 to December 2019. Patients with clinical evidence of acute upper gastrointestinal bleeding within 12 hours were inducted consecutively. Patients were randomly assigned to erythromycin (500 mg) suspension or placebo, orally three hours before endoscopy. One endoscopist performed all the procedures with the same double-channel video endoscope. The primary endpoint was endoscopic quality. The secondary endpoints were the need for second-look endoscopy within 48 hours, endoscopy related complications, therapeutic procedure performed or not during endoscopy, number of blood transfusions, and length of hospital stay. Results A total of 60 patients were included in the study; 30 received erythromycin and 30 received placebo. Out of these, 60% were male and 40% were female. The mean age was 53.68 ± 16.64. Quality of endoscopy was much better in the erythromycin group (83.3%) as compared to placebo (40%). Erythromycin did not shorten the endoscopic duration (15.53 vs. 14.33 minutes in the placebo group; p=0.216) and length of hospital stay (5.23 in erythromycin vs. 5.40 days in placebo group; p=0.807). Statistically no significant association was found between use of erythromycin and establishment of cause of bleed, need for second-look endoscopy, number of blood transfusions and number of endoscopic therapeutic procedures. Conclusion Erythromycin oral suspension before endoscopy in patients with acute upper gastrointestinal bleeding produced good quality of endoscopy in our study. It improved the visualization of gastric and duodenal mucosa significantly. However, it did not shorten the duration of endoscopy or hospital stay. There was no significant difference in number of second-look endoscopies and blood transfusions as well.
