The children were grouped into 6-12 and 12-18 years of age groups. These groups were also divided into 2 subgroups(presence and absence of EV). All of the patients underwent a complete biochemical and radiologic evaluation. The PC(n/mm^3)-to-SD(mm) ratio was calculated for each patient. RESULTS Sixty-nine of 98(70.4%) patients had EV. The presence of ascites in all age groups was significantly associatedwith the presence of EV. There were no differences in serum albumin levels, PC, SD and the PC-to-SD ratio between the presence and absence of EV groups in both age groups(P > 0.05). CONCLUSION Laboratory and radiologic parameters, including the PC-to-SD ratio as a non-invasive marker(except for the presence of ascites), was inappropriate for detecting EV in children with cirrhosis.展开更多

The patients included in the study were the cirrhotic of black race hospitalized having carried out an abdominal ultrasound with measurement of the spleen diameter (SD), an eso-gastro-duodenal endoscopy, and a blood count with platelet count (PC). The first primary endpoint was the diagnosis of esophageal varices in cirrhosis. Cirrhosis was retained by the combination of clinical, biological, ultrasound and endoscopic arguments. The OVs were distributed according to size and the presence of red signs. The platelet count, and the measurement of the spleen to calculate the PC/SD ratio were the second endpoint. The secondary endpoints studied were, the viral and ethyl etiologies of the cirrhosis, the Chlid-Pugh prognostic score. Performance was assessed using the ROC curve. The difference was significant for p less than 0.05. <strong>Results:</strong> The study included 101 patients;they were 79 men (78.2%) and 22 women (21.8%). The mean age of the cirrhotic patients was 48 ± 14. Esophageal varices were present in (n = 93;92%) of cases. The different etiologies were hepatitis B virus (HBV) (n = 65;78.3%), hepatitis C virus (HCV) (n = 21;25, 3%), and alcohol (n = 6;7.2%). Platelet count (PC) < 100,000/mm3 was statistically related to the presence of OV with red signs. Splenomegaly (SD > 130 mm) and PC/SD ratio < 1000 were significantly related to the presence of OVs and large OVs. SD with a cutoff of > 102 mm predicted 75% of OVs (AUROC = 0.797). CP with a cutoff < 131,000/mm3, predicted 100% of OVs (AUROC = 0.756). The PC/SD ratio < 1205 diagnosed 100% of OV (AUROC = 0.801). The PC/SD ratio < 818 and SD > 129 mm predicted large OVs. <strong>Conclusion:</strong> Platelet count, spleen diamater, and PC/SD ratio were all performant for the diagnosis of OVs in our setting with better diagnostic performance for PC/SD. This report could help initiate prophylactic treatment for OVs rupture in cirrhotic patients in health centers where gastrointestinal endoscopy is lacking.展开更多
