Grant-McAuley W, Laeyendecker O, Monaco D, Chen A, Hudelson S, Klock E, et al.
BMC Infect Dis . 2022 Nov; 22(1):838. PMID: 36368950
Background: Multi-assay algorithms (MAAs) are used to estimate population-level HIV incidence and identify individuals with recent infection. Many MAAs use low viral load (VL) as a biomarker for long-term infection....

Govender Y, Morrison C, Chen P, Gao X, Yamamoto H, Chipato T, et al.
Sex Transm Infect . 2022 Sep; 99(5):311-316. PMID: 36104248
Objectives: To examine innate immunity predictors of HIV-1 acquisition as biomarkers of HSV-2 risk and biological basis for epidemiologically established HIV-1 predisposition in HSV-2 infected women. Methods: We analysed longitudinal...

Kammers K, Chen A, Monaco D, Hudelson S, Grant-McAuley W, Moore R, et al.
Front Immunol . 2021 Sep; 12:740395. PMID: 34512672
Introduction: Low HIV viral load is associated with delayed disease progression and reduced HIV transmission. HIV controllers suppress viral load to low levels in the absence of antiretroviral treatment (ART)....

Nowak R, Liska T, Bentzen S, Kim E, Chipato T, Salata R, et al.
J Acquir Immune Defic Syndr . 2021 Feb; 87(2):789-793. PMID: 33587502
Background: Herpes simplex virus type-2 (HSV-2) seropositive persons have a 3- to 5-fold higher risk of acquiring HIV, possibly because of HSV-2-induced inflammation and recruitment of susceptible immune cells to...

Peebles K, Palanee-Phillips T, Balkus J, Beesham I, Makkan H, Deese J, et al.
J Acquir Immune Defic Syndr . 2020 Jul; 85(2):156-164. PMID: 32701820
Background: HIV-1 risk scoring tools could help target provision of prevention modalities such as pre-exposure prophylaxis. Recent research suggests that risk scores for women aged 18-45 may not predict risk...

Morrison C, Hofmeyr G, Thomas K, Rees H, Philip N, Palanee-Phillips T, et al.
AIDS Res Hum Retroviruses . 2020 May; 36(8):632-640. PMID: 32394723
Limited data exist on the effects of contraceptives on HIV disease progression. We studied the association between intramuscular injectable depot medroxyprogesterone acetate (DMPA-IM), the copper intrauterine device (IUD), and the...

Morrison C, Chen P, Yamamoto H, Gao X, Chipato T, Anderson S, et al.
J Acquir Immune Defic Syndr . 2020 Jan; 84(1):85-91. PMID: 31985699
Background: We previously reported association of increased cervical RANTES and decreased secretory leukocyte protease inhibitor (SLPI) with higher risk of HIV acquisition in reproductive-age women. We now examine the interaction...

PLoS One . 2020 Jan; 15(1):e0224359. PMID: 31914129
Sexually transmitted infections (STIs) and vaginal dysbiosis (disturbed resident microbiota presenting with abnormal Nugent score or candidiasis) have been associated with mucosal inflammation and risk of HIV-1 infection, cancer and...

Hofmeyr G, Morrison C, Baeten J, Chipato T, Donnell D, Gichangi P, et al.
Gates Open Res . 2019 Sep; 1:17. PMID: 29355224
, animal, biological and observational clinical studies suggest that some hormonal methods, particularly depot medroxyprogesterone acetate - DMPA, may increase women's risk of HIV acquisition. DMPA is the most common...

Morrison C, Fichorova R, Chen P, Kwok C, Deese J, Yamamoto H, et al.
AIDS Res Hum Retroviruses . 2018 Jul; 34(10):889-899. PMID: 30047279
Hormonal contraception (HC), particularly injectable depot-medroxyprogesterone acetate (DMPA), has been associated with increased HIV acquisition and higher levels of cervical regulated upon activation, normal T-cell expressed, and secreted (RANTES), also...
