1,200 pregnant women (600 HIV+ mothers and 600 HIV-controls) in their third trimester were enrolled from January 2016 to June 2019. Participants are being followed as mother-baby pairs at birth, within 10 days of life 6, 10, 14 24, 48, 72 and 96 weeks of age. At each visit clinical examinations are being used to assess health and the impact of environmental factors. In addition, questionnaires are administered and bio-samples for laboratory tests. The design of the study is non-interventional cohort but participants are being offered advice regarding health and hygiene.

Only anonymous data will be stored at local sites and transferred between sites for collaborative research efforts. All original data will be stored locally at the UZ-CHS for at least 10 years on suitable electronic devices. Data transfer with collaborating partners will be encrypted. using EGAcryptor. With our European partners we will follow the current European General Data Protection Regulation effective May 25, 2018.

Shear Wave sonoelastography (SWE) was performed in patients who were scheduled for a non-focal liver biopsy.

Shear Wave Sonoelastography for Fibrosis Assessment

Sex: Female, Male

Liver elasticity/stiffness was assessed via SE and compared against results of liver biopsy as read by a single pathologist using the Meta-analysis of Histological Data in Viral Hepatitis (METAVIR) 5-point scale (F [Fibrosis]0=no fibrosis, F1=portal fibrosis without septa, F2=portal fibrosis with few septa, F3=numerous septa without cirrhosis, and F4=cirrhosis). Using SE, fibrosis is measured in kilopascals (kPa) with normal values equaling approximately 5.5 kPa (normal liver stiffness ranges between 3.3-7.8 kPa). Significant Fibrosis (F3): = or > 7.6 kPa, Cirrhosis (F4): = or > 9.0- 26 kPa. A higher number corresponds to an increase in stiffness and hepatic fibrosis.
