Background: Dolutegravir (DTG)-based dual therapy is becoming a new paradigm for both the initiation and maintenance of HIV treatment. The SIMPL'HIV study investigated the outcomes of virologically suppressed patients on standard combination antiretroviral therapy (cART) switching to DTG + emtricitabine (FTC). We present the 48-week efficacy and safety data on DTG + FTC versus cART.Methods and Findings: SIMPL'HIV was a multicenter, open-label, non-inferiority randomized trial with a factorial design among treatment-experienced people with HIV in Switzerland. Participants were enrolled between 12 May 2017 and 30 May 2018. Patients virologically suppressed for at least 24 weeks on standard cART were randomized 1:1 to switching to DTG + FTC or to continuing cART, and 1:1 to simplified patient-centered monitoring versus standard monitoring. The primary endpoint was the proportion of patients virologically suppressed with <100 copies/ml through 48 weeks. The secondary endpoints included virological suppression at 48 weeks according to the US Food and Drug Administration (FDA) snapshot analysis. Non-inferiority of DTG + FTC versus cART for viral suppression was assessed using a stratified Mantel-Haenszel risk difference, with non-inferiority declared if the lower bound of the 95% confidence interval was greater than -12%. Adverse events were monitored to assess safety. Quality of life was evaluated using the PROQOL-HIV questionnaire. Ninety-three participants were randomized to DTG + FTC, and 94 individuals to cART. Median nadir CD4 count was 246 cells/mm3; median age was 48 years; 17% of participants were female. DTG + FTC was non-inferior to cART. The proportion of patients with viral suppression (<100 copies/ml) through 48 weeks was 93.5% in the DTG + FTC arm and 94.7% in the cART arm in the intention-to-treat population (risk difference -1.2%; 95% CI -7.8% to 5.6%). Per-protocol analysis showed similar results, with viral suppression in 96.5% of patients in both arms (risk difference 0.0%; 95% CI -5.6% to 5.5%). There was no relevant interaction between the type of treatment and monitoring (interaction ratio 0.98; 95% CI 0.85 to 1.13; p = 0.81). Using the FDA snapshot algorithm, 84/93 (90.3%) participants in the DTG + FTC arm had an HIV-1 RNA viral load of <50 copies/ml compared to 86/94 (91.5%) participants on standard cART (risk difference -1.1%; 95% CI -9.3% to 7.1%; p = 0.791). The overall proportion of patients with adverse events and discontinuations did not differ by randomization arm. The proportion of patients with serious adverse events was higher in the cART arm (16%) compared to the DTG + FTC arm (6.5%) (p = 0.041), but none was considered to be related to the study medication. Quality of life improved more between baseline and week 48 in the DTG + FTC compared to the cART arm (adjusted difference +2.6; 95% CI +0.4 to +4.7). The study's main limitations included a rather small proportion of women included, the open label design, and its short duration.Conclusions: In this study, DTG + FTC as maintenance therapy was non-inferior to cART in terms of efficacy, with a similar safety profile and a greater improvement in quality of life, thus expanding the offer of 2-drug simplification options among virologically suppressed individuals.Trial Registration: ClinicalTrials.gov NCT03160105.

Background: Rilpivirine is safe and effective in HIV-naïve patients with low baseline HIV-RNA or in switch strategy. It offers the advantages of few drug-drug interactions and a favourable toxicity profile. We aimed to determine the reasons for prescribing the rilpivirine (RPV)/tenofovir disoproxil (TDF)/emtricitabine (FTC) co-formulation within the Swiss HIV Cohort Study and to assess its effectiveness and safety over a 24 months period.Methods: All individuals enrolled in the Swiss HIV Cohort Study who initiated a RPV/TDF/FTC co-formulation between April 2013 and March 2014 were included. Primary outcomes were the HIV-RNA viral load (copies/mL) and CD4 cell count (cells/mm3) at 6, 12 and 24 months. Reasons for a switch to RPV/TDF/FTC were evaluated through a standardized questionnaire. We also assessed discontinuation and reasons for discontinuation of RPV/TDF/FTC until October 30, 2015.Results: Of 644 individuals who started the RPV/TDF/FTC co-formulation, only 7.5% were treatment-naïve. At 24 months, viral suppression (HIV-RNA <50 copies/mL) was achieved in 100% and 96.7% of cART-naïve and cART-experienced patients respectively. The switch to RPV was mainly done for simplification (44.6%) and to overcome central nervous system toxicity symptoms due to efavirenz (24%). Six months after switch, 74.8% of patients reported an improvement of psycho-neurological symptoms with continued improvement at 12 months for almost 80%. However, one quarter of patients reported a discontinuation of RPV/TDF/FTC on October 30, 2015 after a median time of 18.4 months. Reasons for discontinuation included physician decision (5.3%) and side-effects (3.9%) mainly related to the central nervous system and to renal toxicity.Conclusion: The RPV/TDF/FTC co-formulation was safe and effective throughout 24 months of follow-up but barely prescribed for HIV-naïve patients. Despite excellent virological suppression among both treatment-naïve and -experienced patients, we observed a high rate of treatment discontinuation. [ABSTRACT FROM AUTHOR]- Published

Operational research is necessary to improve the access to and delivery of tuberculosis prevention, diagnosis and treatment interventions for people living with HIV. We conducted an extensive review of the literature and reports from recent expert consultations and research-related meetings organized by the World Health Organization and the Stop TB Partnership to identify a TB/HIV operational research agenda. We present critical operational research questions in a series of key areas: optimizing TB prevention by enhancing the uptake of isoniazid preventive therapy and the implementation of infection control measures; assessing the effectiveness of existing diagnostic tools and scaling up new technologies; improving service delivery models; and reducing risk factors for mortality among TB patients living with HIV. We discuss the potential impact that addressing the operational research questions may have on improving programmes' performance, assessing new strategies or interventions for TB control, or informing global or national policy formulation. Financial resources to implement these operational research questions should be mobilized from existing and new funding mechanisms. National TB and HIV/AIDS programmes should develop their operational research agendas based on these questions, and conduct the research that they consider crucial for improving TB and HIV control in their settings in collaboration with research stakeholders.

This study aims to evaluate the association between dolutegravir (DTG) pharmacokinetic parameters and weight changes in treatment‐experienced people with HIV (PWHIV) from the Simpl'HIV study newly switched to a dual DTG‐based regimen. We used multivariable linear regressions to evaluate the association between DTG pharmacokinetic parameters at week 48 (derived using an established model) and weight change between week 0 and week 48. We adjusted our model for potential confounders including CD4 nadir, female sex, African origin, age, weight at week 0 and presence of a non‐nucleoside reverse transcriptase inhibitor‐based regimen before switch to DTG. The analysis included data from 39 PWHIV. An average significant weight gain of 2.4 kg was observed between baseline and week 48. DTG plasma exposure was not significantly associated with weight gain, even after adjusting for potential confounders (P =.9). We found no significant association between DTG pharmacokinetic parameters and weight gain amongst PWHIV newly switched to a DTG‐based dual regimen. [ABSTRACT FROM AUTHOR]

Introduction In HIV patients, haemophagocytic syndrome (HPS) may occur in the presence of cancer, concomitant viral infection, HIV primo-infection or at the initiation of highly active antiretroviral therapy (HAART). Hodgkin lymphoma remains a rare cause of HPS. We describe a case of HPS with very high Epstein Barr virus (EBV) load in a HIV patient as initial manifestation of Hodgkin lymphoma. Materials and Methods A 29-year-old HIV positive man, successfully treated with HAART with an undetectable viral load and CD4 cells count of 438/µl, was admitted for high fever of unknown origin. Laboratory results showed a pancytopenia with haemoglobin at 82 g/l, lymphocyte count at 0.36G/l and platelets count at 47G/l; a highly elevated ferritine >7500 µg/l; increased lactate dehydrogenase at 885U/l and soluble IL2 receptor (CD25) >60 ng/ml. EBV load was measured and confirmed at 2,600,000 copies/ml. A PET-CT imaging showed diffuse elevated metabolic activity in the bone marrow and in two lesions in the spleen without lymphadenopathy. Bone marrow and liver biopsies revealed images of haemophagocytosis and lymphocyte depleted Hodgkin lymphoma. Treatment consisted in etoposid, steroids, and R-ABVD (rituximab, doxorubicin, bleomycin, vinblastine, dacarbazine) chemotherapy. The patient completed six cycles of chemotherapy. We reviewed the literature in PubMed with the following keywords: HPS, HIV, EBV, Hodgkin lymphoma. Results We identified four publications and two reviews reporting cases of HPS associated with Hodgkin lymphoma in HIV patients with either a positive EBV load either the presence of encoded EBV RNA in tumour cells. Twenty-two cases (including one pediatric case) were described. Among adults, mostly men, the median age was <50 years and immune suppression was marked with a median CD4 cell count<100 cells/µl, even in patients receiving HAART. When measured, EBV load in the serum was high. Prognosis was poor with a high mortality despite adequate treatment consisting in steroids and chemotherapy, with or without etoposide (Table 1). Conclusions Our case report and the review of literature suggest that physicians should be aware of the association between EBV infection/reactivation and Hodgkin lymphoma as a cause of HPS in HIV patients, even if successfully treated with HAART. The pathogenesis of these three interrelated conditions (viral infection, oncogenesis and immunologic reaction) remains unclear. [ABSTRACT FROM AUTHOR]

Introduction Morphological and metabolic complications in HIV patients on antiretroviral therapy remain a challenge. While new cases of lipoatrophy (LA) disappear, irreducible central lipohypertrophy (LH) and metabolic complications require highly specialized management. We described a day hospital dedicated to lipodystrophy (LD) and metabolic disorders in HIV patients on treatment in Geneva, Switzerland, with a focus on LH. Materials and Methods The 'Groupe Lipo & Metabolism' is a multidisciplinary consultation where patients undergo a standard evaluation including questionnaire, physical examination, dual-energy x-ray absorptiometry (DEXA) and L5-level CT scans, blood tests and consultations with various specialists. Based on prospectively maintained data, we describe clinical, biological and radiological characteristics of patients ≥18 years who attended the consultation between 2008 and 2013. We defined LH by CT scan, the gold standard method, as abdominal visceral adipose tissue (VAT) ≥130 cm2, value associated with increased risk of cardiovascular event. Results A total of 195 patients attended the consultation during study period. Reasons for referral included LH in 28.3%, LA in 25% and mixed syndrome in 15.5% of cases. Metabolic disorders accounted for 19% of referrals with or without LD features. Among patients with a CT scan performed (n=183), 46 (25%) had LH with a VAT ≥130 cm2. In this population, mean age was 49.1 years and 53.6% were male. HIV viral load was <50 cp/ml in 87% of patients. Mean body mass index was 24.6 kg/m2. Mean waist to hip ratio (WHR) was 0.98 for males and 0.89 for females. A total of 9.8%, 29.5% and 35% of patients had abnormal levels of total cholesterol (≥6.5 mmol/L), triglycerides (≥2.0 mmol/L) and HDL cholesterol (≤1.0 mmol/L), respectively. Mean fasting glycaemia was 5.7 mmol/L and HbA1c was >6% in 10.5% of patients. Vitamin-D level was <75 nmol/L in 70.7% of patients. Respectively 31.2% and 12.1% of patients had osteopenia and osteoporosis on the spine and 44.8% and 6.6% on the hip neck. Factors associated with a VAT≥130 cm2 included male gender (OR 3.7 [95% CI 1.7-8.2] p<0.001), triglycerides ≥2 mmol/L (OR 2.6 [95% CI 1.3-5.4] P<0.01) and increase in BMI category (OR 1.8 [95% CI 1.2-2.8] p<0.01). Conclusions Lipohypertrophy is a prevalent feature of fat redistribution among HIV patients on treatment. Risk factors for LH include male gender, dyslipidemia and overweight. Glucose impairment and bone disorders are also common. A multidisciplinary approach is important to identify and promptly address these disorders. Acknowledgments The 'Groupe Lipo & Metabolism' team.

Tuberculosis affected an estimated 8.8 million people and caused 1.4 million deaths globally in 2010, including a half-million women and at least 64 000 children. It also results in nearly 10 million cumulative orphans due to parental deaths. Moreover, it causes 6%–15% of all maternal mortality, which increases to 15%–34% if only indirect causes are considered. Increasingly, more women with tuberculosis are notified than men in settings with a high prevalence of human immunodeficiency virus (HIV), and maternal tuberculosis increases the vertical transmission of HIV. Tuberculosis prevention, diagnosis, and treatment services should be included as key interventions in the integrated management of pregnancy and child health. Tuberculosis screening using a simple clinical algorithm that relies on the absence of current cough, fever, weight loss, and night sweats should be used to identify eligible pregnant women living with HIV for isoniazid preventive therapy or for further investigation for tuberculosis disease as part of services for prevention of vertical HIV transmission. While implementing these simple, low-cost, effective interventions as part of maternal, neonatal, and child health services, the unmet basic and operational tuberculosis research needs of children, pregnant, and breastfeeding women should be addressed. National policy makers, program managers, and international stakeholders (eg, United Nations bodies, donors, and implementers) working on maternal, neonatal, and child health, especially in HIV-prevalent settings, should give due attention and include tuberculosis prevention, diagnosis, and treatment services as part of their core functions and address the public health impacts of tuberculosis in their programs and services.

- Abstract
This article reviews the antiretroviral therapy (ART) initiation criteria from national treatment guidelines for 70 countries and determines the extent of consistency with the current World Health Organization (WHO) recommendations.Published ART guidelines were collected from the Internet, databases, and WHO staff. ART eligibility criteria for asymptomatic people, pregnant women, people with HIV-associated tuberculosis, serodiscordant couples, injecting drug users, men who have sex with men, and sex workers were abstracted from them. Multiple regression analysis was used to determine the relation between ART eligibility criteria, ART coverage, and various population characteristics and policy interventions.Of the 70 countries, 42 (60%) follow WHO’s ART guidelines for asymptomatic people and 31 (44%) for pregnant women, recommending ART at CD4 count of 350 cells/mm3. Twenty-three (33%) countries recommend ART for people with HIV-associated tuberculosis irrespective of CD4 count. Nineteen countries are also recommending or considering earlier ART above CD4 count 350 cell/mm3 for asymptomatic people, pregnant women, and/or serodiscordant couples. Multiple linear regression analysis shows that HIV prevalence, year of publication of guidelines, and HIV expenditure are significantly associated with published ART eligibility criteria. On average, the ART coverage is similar irrespective of published guidelines being consistent with the WHO recommendation (P < 0.53).Published guidelines from a significant number of countries are not following WHO recommendations. Although published guidelines may not reflect practice, it is important to adapt recommendations and services quickly to reflect the emerging science on the health and prevention benefits of earlier access to ART.

Background: Human immunodeficiency virus (HIV) infection is the strongest risk factor for developing tuberculosis and has fuelled its resurgence, especially in sub-Saharan Africa. In 2010, there were an estimated 1.1 million incident cases of tuberculosis among the 34 million people living with HIV worldwide. Antiretroviral therapy has substantial potential to prevent HIV-associated tuberculosis. We conducted a systematic review of studies that analysed the impact of antiretroviral therapy on the incidence of tuberculosis in adults with HIV infection. Methods and Findings: PubMed, Embase, African Index Medicus, LILACS, and clinical trial registries were systematically searched. Randomised controlled trials, prospective cohort studies, and retrospective cohort studies were included if they compared tuberculosis incidence by antiretroviral therapy status in HIV-infected adults for a median of over 6 mo in developing countries. For the meta-analyses there were four categories based on CD4 counts at antiretroviral therapy initiation: (1) less than 200 cells/μl, (2) 200 to 350 cells/μl, (3) greater than 350 cells/μl, and (4) any CD4 count. Eleven studies met the inclusion criteria. Antiretroviral therapy is strongly associated with a reduction in the incidence of tuberculosis in all baseline CD4 count categories: (1) less than 200 cells/μl (hazard ratio [HR] 0.16, 95% confidence interval [CI] 0.07 to 0.36), (2) 200 to 350 cells/μl (HR 0.34, 95% CI 0.19 to 0.60), (3) greater than 350 cells/μl (HR 0.43, 95% CI 0.30 to 0.63), and (4) any CD4 count (HR 0.35, 95% CI 0.28 to 0.44). There was no evidence of hazard ratio modification with respect to baseline CD4 count category (p = 0.20). Conclusions: Antiretroviral therapy is strongly associated with a reduction in the incidence of tuberculosis across all CD4 count strata. Earlier initiation of antiretroviral therapy may be a key component of global and national strategies to control the HIV-associated tuberculosis syndemic. [ABSTRACT FROM AUTHOR]
