Frequency of portal hypertensive gastropathy and its relationship with biochemical, haematological and endoscopic features in cirrhosis

ABSTRACT

To determine the frequency of portal hypertensive gastropathy [PHG] and its relation with biochemical, haematological and endoscopic findings in cirrhotic patients. Cross-sectional analytical study. Jinnah Postgraduate Medical Centre, Karachi, Medical Unit-III, Ward-7, from June 2009 to December 2010. Patients with diagnosis of cirrhosis and either undergoing screening upper gastrointestinal [GI] endoscopy or presented with acute upper GI bleeding were included in the study. Portal hypertensive gastropathy and oesophageal varices were classified using Baveno scoring system. The severity of cirrhosis was classified according to the Child-Pugh criteria. Hypersplenism was assessed by the reduction of haemoglobin, leucocytes and platelets. Out of 217 patients, 148 were males [68.2%] and 69 were females [31.8%] with ages ranging from 15-85 years, [mean 48.06 years]. There were 144 HCV +ve patients [66.4%], 36 HBV +ve patients [16.6%], 15 HCV/HBV co-infected patients [6.9%] and only 1 [0.5%] had co-infection of HBV/HDV. Twenty-one patients [9.7%] were classified as having cryptogenic cirrhosis. Out of 172 patients [79.27%], 56 patients [25.8%] had mild and 116 patients [53.5%] were suffering from severe PHG. Significant positive correlation was found between esophageal variceal grade and PHG [r=0.46, p < 0.001] but not with etiology [r=0.05, p=0.41] or hypersplenism [r=0.08, p=0.22]. The frequency of PHG was 79.27% in the studied group. The grade of oesophageal varices had significant relation with PHG that is the severity of PHG increased with the grade of oesophageal varices, suggesting common pathophysiology of both entities
