15. Hemophagocytic Lymphohistiocytosis Due to Primary HHV-8 Infection in a Liver Transplant Recipient

Author

Cohen, Gabriel M., Langer, Arielle L., Sima, Hamid, Chang, Charissa, Troy, Kevin, and Taimur, Sarah

Abstract

Human herpesvirus-8 (HHV-8) remains best known as an oncogenic virus, but nonneoplastic disease manifestations, such as bone marrow failure or hemophagocytic lymphohistiocytosis (HLH) have gained greater recognition in recent years. In organ transplantation, HHV-8 infection commonly occurs with reactivation of latent virus among recipients from endemic regions of the world or due to transmission from the organ donor. We describe a case of HHV-8–associated HLH in a liver transplant recipient at increased risk for primary infection. Our case highlights the risk of non–donor-derived, posttransplant primary HHV-8 infection, and demonstrates that HLH can be a life-threatening complication of this infection.

18. Role of Education in HIV Clinical Outcomes in a Tuberculosis Endemic Setting.

Author

Cohen, Gabriel M, Werner, Lise, Gengiah, Santhanalakshmi, and Naidoo, Kogieleum

Abstract

This study evaluated how educational attainment impacts clinical outcomes of HIV-positive patients in Durban, South Africa. The authors conducted a prospective study of 466 adult HIV-positive patients initiating antiretroviral therapy (ART) at an urban TB-HIV clinic from October 2004 to June 2007. The level of educational attainment (highest grade completed) was assessed at ART initiation. The authors measured tuberculosis treatment outcomes as well as death, lost to follow-up, viral suppression (HIV RNA <400 copies/mL), and immunologic response (CD4 ≥200 cells/mm(3)) at 6, 12, and 24 months after ART initiation. After 24 months of ART initiation, there were 43 deaths; viral suppression and immunologic response were observed in 88% and 83% of the remaining patients, respectively. The authors found no association between level of educational attainment and mortality (P = .12), loss to follow-up (P = .85), virologic response (P = .51), or immunologic response (P = .63). Similar findings were observed at 6 and 12 months post-ART initiation. [ABSTRACT FROM AUTHOR]

Abstract

Setting: We conducted a retrospective study among HIV-infected adult suspects (≥18 years) with pulmonary tuberculosis (TB), who underwent Xpert MTB/RIF (Xpert) testing at McCord Hospital and its adjoining HIV clinic in Durban, South Africa., Objective: To determine if Xpert testing performed at a centralized laboratory accelerated time to TB diagnosis., Design: We obtained data on sputum smear microscopy [acid-fast bacilli (AFB)], Xpert, and the rationale for treatment initiation from medical records. The primary outcome was "total diagnostic time," defined as time from sputum collection to clinicians' receipt of results. A linear mixed-effect model compared the duration of steps in the diagnostic pathway across testing modalities., Results: Among 403 participants, the median "total diagnostic time" for AFB and Xpert was 3.3 and 6.4 days, respectively (P < 0.001). When compared with AFB, the median delay for Xpert "laboratory processing" was 1.4 days (P < 0.001) and "result transfer to clinic" was 1.7 days (P < 0.001). Among 86 Xpert-positive participants who initiated treatment, 49 (57%) started treatment based on clinical suspicion or AFB-positive results, whereas only 32 (37%) started treatment based on Xpert-positive results., Conclusions: In our setting, Xpert results took twice as long as AFB results to reach clinicians. Replacing AFB with centralized Xpert may delay TB diagnoses in some settings.
