Highlights from the 9th IAS conference on HIV science, 23-26 July 2017, Paris, France

The 9th International AIDS Society Conference on HIV Science (IAS 2017) took place at the Palais des Congrès, in Paris, France, from 23 to 26 July 2017, chaired by Linda-Gail Bekker and Jean-François Delfraissy. It was organised by the International AIDS Society (IAS) in partnership with ANRS (the French national agency for research on AIDS and viral hepatitis), bringing together more than 6000 leading scientists, researchers and HIV professionals from around the world. The Conference featured more than 1800 abstracts selected for oral and poster presentations out of over 4300 submissions, in addition to plenary sessions and satellite symposia. Prevention was high on the agenda of this year's Conference. Data relevant to children, adolescents and adults with HIV on recent advances in the understanding of viral–host interactions, targeting of the HIV reservoir, new oral and long-acting antiretroviral drugs, strategies for simplification of treatment regimens, immune-based therapies, pre-exposure prophylaxis (PrEP) to HIV, prevention of mother-to-child transmission, prophylactic and therapeutic vaccines, as well as comorbidities including hepatitis, were presented with an emphasis on translating science into practice and policies

Symptomatic Primary Infection Due to Human Immunodeficiency Virus Type 1: Review of 31 Cases

In this series of 31 patients with acute infection due to human immunodeficiency virus (HIV) type 1, the male-to-female ratio was 3.4:1 and the mean age was 31.3 years. Sexual transmission accounted for 83.9% of cases; 45.2% of the patients were homosexual and 38.7% were heterosexual. The mean duration of symptoms and signs was 21 days (range, 5-60 days). Fever (87.1%) and skin rash (67.7%) were most commonly reported. Physical examination findings were abnormal for 96% of the patients; the oral cavity (76.7%) and the skin (73.3%) were the most frequently involved sites. Thirteen of 25 patients with sexually acquired infection had genital or oral ulcers, whereas five intravenous drug users had none (P = .052). Thrombocytopenia was the most common hematologic abnormality and was detected in 17 of 23 patients tested. P24 antigenemia, an initially negative screening test for HIV antibody, and a low CD4+ lymphocyte count were noted in 23 of 29, 23 of 30, and 14 of 21 tested patients, respectivel

Severity and Prognosis of Acute Human Immunodeficiency Virus Type 1 Illness: A Dose-Response Relationship

This study examined the relationship between the severity of acute human immunodeficiency virus type 1 (HIV-1) illness and disease progression and death. The population included 218 patients with acute HIV-1 illness and 41 asymptomatic patients who underwent HIV-1 seroconversion; the patients were followed up prospectively. We analyzed progression to Centers for Disease Control and Prevention clinical categories B and C (AIDS-defining conditions) and death according to an additive clinical score (CS) based on six predictive clinical features at the time of acute HIV-1 infection. Compared with patients with a CS of 0 (asymptomatic patients), those with a CS of 3-4 and 5-6 had faster progression to category B disease (adjusted hazard ratio [HR], 1.39; 95% confidence interval [CI], 1.01-1.92; and HR, 1.80; 95% CI, 1.34-2.40; respectively); those with a CS of 5-6 had faster progression to category C disease (HR, 1.37; 95% CI, 1.01-1.89) and death (HR, 2.05; 95% CI, 1.27-3.32). Thus, the number of symptoms and signs at the time of acute HIV-1 illness affects disease progression and survival, even in symptomatic patients who have undergone seroconversio
