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.

To determine biomarkers for endothelial dysfunction including microbial translocation in HUU, HEU and HEI infants and association with household hygiene at delivery, 6, 48 and 96 weeks of age.

To determine antenatal reference ranges for MUAC, haemoglobin from FBC analyses, and biochemistry (kidney function, liver function tests, bone, lipid profiles) in mothers with a favourable outcome of pregnancy

To determine maternal- infant microbiota16S sequencing in pregnancy and relate it to infant immune development and atopy (anti-inflammatory (IL-4, -5, -13) and regulatory cytokines (IL-10, TGF-β) at delivery, 6 weeks 48 and 96 weeks of age.

Bacterial full genome metagenomics shotgun sequencing to identify the microbiota metabolic potential (i.e. bacterial genes present will be done) and mass spectrometry will be performed for analysis of small intestinal content (metabolome).

Wide range of nutritional profiles and HAART levels spectrometry will be performed for analysis of at least 700 metabolites including amino acids and lipids will be performed in plasma, breast milk and stool samples

To characterize pathogen genetic diversity including HIV, HBV, HCV, CMV subtypes, prevalent in our study population at time of infection

To determine host genetic markers for infectious disease susceptibility including human leukocyte antigen (HLA) and killer immunoglobulin like receptor (KIR) gene variants and their association with infection rates of HIV and co-infections in mothers and their infants.

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.

Faecal Microbiota Transplantation in Irritable Bowel Syndrome

Randomised Placebo Controlled Trial of Faecal Microbiota Transplantation in Irritable Bowel Syndrome

This assessment will be obtained by defining the response (Yes or No) to the following question.
"Please consider how you felt in the past week in regard to your IBS, in particular your overall well-being, and symptoms of abdominal discomfort or pain, bloating or distension and altered bowel habit .Compared to the way you usually felt before the beginning of the trial, have you had adequate relief of your IBS-symptoms?"

The primary symptoms of IBS will be scored on a six point Likert scale at baseline, week 4 and at end of study. The following symptoms will be assessed and recorded: abdominal pain/discomfort, bloating/distension, sense of incomplete evacuation, straining at stool, urgency of bowel movement, passage of gas and mucus, bowel habit satisfaction. Each symptom will be assessed using a 6-point scale, where 0 = none to 5 = very severe. Bowel habit satisfaction will be assessed using a 6-point scale where 0 = very satisfied and 5 = very dissatisfied. Overall assessment of IBS symptoms will be also be scored on a 6 - point scale. An IBS composite score(15 point score) representing the sum of individual scores for abdominal pain/discomfort, bloating/distension, and bowel movement difficulty (straining at stool or urgency of bowel movement) will be calculated.

At baseline and at the end of the study each subject will complete an IBS-specific quality of life questionnaire (IBS-QOL)

At baseline and at the end of the study each subject will complete the Hospital Anxiety and Depression (HAD) Scale.

Patients will be monitored throughout the study period and they will be recorded as per the The Consolidated Standards of Reporting Trials (CONSORT) criteria

We will characterise all participants' microbiota composition at baseline and at the end of study to determine if there is a subgroup of patient/donor combinations, based on their microbiota composition, in whom a positive response to FMT was obtained. This would be very valuable for future optimization of a positive primary outcome.

The intervention participants will receive the Living Well with Diabetes Program. The program will consist of educational DVDs with integrated storytelling about how community members accepted their disease and overcame barriers to medication adherence, plus one-on-one telephonic peer coaching.

At enrollment, the investigators will provide an educational DVD on general health and wellness topics including vaccination, cancer screening, osteoporosis and other topics not related to diabetes care. There will be no peer storytelling on these DVDs.
