Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- The ability to understand and give informed consent to participate.
- HIV-1 infected with stable ART > 12 months
- Plasma HIV-RNA < 50 copies/ml
- Plasma homocysteine ≥ 12 μmol/L (subjects with < 12 μmol/L will be included in the analysis of secondary endpoint 3 (see 5.4).
- Male or female, age 18 or older.
Exclusion Criteria:
- Treatment with trimethoprim-sulfamethoxazole or methotrexate
- Ongoing B6, B12 or folate substitution
- Antiepileptic treatment
- Small bowel or ventricular resection
- Disturbed absorption in small bowel (Mb Crohn, untreated coeliac disease)
- Ongoing neurological disease or severe psychiatric disease
- Any malignant tumor in the history.
- Severe ongoing infection or opportunistic infection
- AUDIT > 7 for men and > 5 for women
- MADRS > 20
- Significant B12 or folate deficiency that indicate substitution (all subjects will be offered adequate substitution, they will be included in the analysis of secondary endpoint 3 (see 5.4)).
- Pregnancy at screening visit, or planning pregnancy during study period is an exclusion criteria. (Not due to toxicity of Triobe, but to elevated risk of being prescribed B-vitamins outside of trial. If study object gets pregnant during study, she can continue the study but must be excluded if she starts treatment with other B-vitamin treatment than Triobe.)
