BACKGROUND & AIMS:

Detecting portal hypertension (PH) before the development of varices is important for prognosis and for designing interventional studies. None of the available strategies is used in practice. We evaluated a sequential screening-diagnostic strategy based on clinical data and transient elastography (TE) to detect PH in asymptomatic outpatients with liver disease.

METHODS:

Consecutive patients with chronic liver disease and no previous diagnosis of PH were screened by TE. Patients with liver stiffness (LS) ⩾ 13.6 kPa were further evaluated by endoscopy and hepatic venous pressure gradient (HVPG). For analysis, patients were classified in 3 groups: group A, platelets ⩾ 150,000/mm(3), normal abdominal ultrasound; group B, platelets <150,000/mm(3), normal ultrasound; group C, platelets <150,000/mm(3), abnormal ultrasound (splenomegaly, nodular liver surface).

RESULTS:

250 patients were evaluated (69% group A, 20% group B, 11% group C). In 9% elastography was non-valid. LS ⩾ 13.6 was found in 54 patients (8% A, 43% B, and 81% C, p<0.001). Endoscopy was performed in 49 of these: 20% had small varices, 0% high-risk varices. No patients from group A had varices, and 90% with varices belonged to group C. HVPG was obtained in 40 patients: 93% had PH (HVPG >5 mmHg) and 65% clinically significant PH (CSPH, HVPG ⩾ 10). Only 3 patients, all from group A, had HVPG <5. All patients from groups B and C with LS ⩾ 13.6 had PH. The LS 25 cut-off was excellent at ruling-in CSPH.

CONCLUSIONS:

A simple strategy based on routine clinical data and TE could be useful to detect early PH among asymptomatic patients with chronic liver disease.
