Is psychological distress associated with decreased memory helper T-cell and B-cell counts in pre-AIDS HIV seropositive men and women but only in those with low viral load?
These findings highlight the importance of assessing the role of HIV viral burden when examining distress-immunity relationships in HIV-infected individuals. The lack of association in those persons with high viral load suggests that, even before AIDS onset, disease-related processes are disrupting CNS and immune system communication.
In our animal model, the higher levels of PYY, GLP-1 and GLP-2 after BPD may be due to gut adaptation and hypertrophy and could be important in inducing and maintaining weight loss after bariatric surgery.
