Abstract
OBJECTIVES: To evaluate whether abdominal ultrasound (US) with a gallbladder (GB) contractility study or motor function test can be used as a diagnostic tool in patients with dengue and warning signs in acute and recovery phases.
METHODS: Fifty-one individuals in the acute phase of dengue presenting with warning signs (dengue group) and 49 healthy individuals without a history of dengue or hepatobiliary disease (control group) were studied with abdominal US and a GB contractility study.
RESULTS: Statistical differences in US measurements of the liver (right lobe, P = .012; left lobe, P = .001) and spleen (P = .008) dimensions, GB wall thickness (P < .001), and the GB emptying fraction (P < .001) were observed in dengue during the acute phase compared with the control group. After 60 days, abdominal US of the dengue group showed a statistical difference in liver (right lobe, P < .001; left lobe, P = .078) and spleen (P < .001) dimensions, GB wall thickness, and the GB emptying fraction (P < .001) compared with the results obtained during the acute phase. Furthermore, a statistical difference in the spleen volume and GB emptying fraction (P < .001) was observed when comparing dengue after clinical recovery and the control group. Abdominal pain in patients with dengue was positively associated with hepatomegaly (P = .031), splenomegaly (P = .008), increased GB wall thickness (P = .016), and a reduced GB emptying fraction (P = .038) during the acute phase and with splenomegaly (P = .001) and a reduced GB emptying fraction (P = .003) after clinical recovery.
CONCLUSIONS: Abdominal US with a GB motor function test can be used as a diagnostic tool in patients with dengue during acute and recovery phases.
