Raltegravir-intensified initial antiretroviral therapy in advanced HIV in Africa: a randomized controlled trial

BACKGROUND: In sub-Saharan Africa, severely immunocompromised HIV-infected individuals have high mortality (10%) shortly after starting antiretroviral therapy (ART). This group also have the greatest risk of morbidity and mortality associated with immune reconstitution inflammatory syndrome (IRIS), a paradoxical response to successful ART. Integrase inhibitors lead to significantly more rapid declines in HIV viral load (VL) than all other ART classes. We hypothesised that intensifying standard triple-drug ART with the integrase inhibitor, raltegravir, would reduce HIV VL faster, and hence reduce early mortality, although this strategy could also risk more IRIS events. METHODS AND FINDINGS: In a 2x2x2 factorial open-label parallel-group trial, treatment-naïve HIV-infected adults, adolescents and children >5 years with CD4 0.7), and despite significantly greater VL suppression with raltegravir-intensified-ART at 4-weeks (343/836 (41.0%) vs 113/841 (13.4%) standard-ART, p<0.001) and 12-weeks (567/789 (71.9%) vs 415/803 (51.7%) standard-ART, p<0.001). Through 48-weeks there was no evidence of differences in mortality (aHR=0.98 (95%CI 0.76-1.28) p=0.91); serious (aHR=0.99 (0.81-1.21) p=0.88), grade-4 (aHR=0.88 (0.71-1.09) p=0.29) or ART-modifying (aHR=0.90 (0.63-1.27) p=0.54) adverse events (the latter occurring in occurring in 59 (6.5%) raltegravir-intensified-ART vs 66 (7.3%) standard-ART); in events judged compatible with IRIS (occurring in 89 (9.9%) raltegravir-intensified-ART vs 86 (9.5%) standard-ART, p=0.79) or hospitalizations (aHR=0.94 (95%CI 0.76-1.17) p=0.59). At 12 weeks, one and two raltegravir-intensified participants had predicted intermediate-level and high-level raltegravir resistance respectively. At 48 weeks, the NRTI mutation K219E/Q (p=0.004), and the NNRTI mutations K101E/P (p=0.03) and P225H (p=0.007), were less common in raltegravir-intensified-ART, with weak evidence of less intermediate or high-level resistance to tenofovir (p=0.06), abacavir (p=0.08) and rilpivirine (p=0.07). Limitations were limited clinical, radiological and/or microbiological information for some participants, reflecting available services at the centres, and lack of baseline genotypes. CONCLUSIONS: Although 12-weeks raltegravir-intensification was well-tolerated and reduced HIV viraemia significantly faster than standard triple-drug ART during the time of greatest risk for early death, this strategy did not reduce mortality or clinical events, and is not warranted. There was no excess of IRIS-compatible events, suggesting integrase inhibitors can be used safely as part of standard triple-drug first-line therapy in severely immuno-compromised individuals

The cost‐effectiveness of prophylaxis strategies for individuals with advanced HIV starting treatment in Africa

Introduction Many HIV‐positive individuals in Africa have advanced disease when initiating antiretroviral therapy (ART) so have high risks of opportunistic infections and death. The REALITY trial found that an enhanced‐prophylaxis package including fluconazole reduced mortality by 27% in individuals starting ART with CD4 <100 cells/mm3. We investigated the cost‐effectiveness of this enhanced‐prophylaxis package versus other strategies, including using cryptococcal antigen (CrAg) testing, in individuals with CD4 <200 cells/mm3 or <100 cells/mm3 at ART initiation and all individuals regardless of CD4 count. Methods The REALITY trial enrolled from June 2013 to April 2015. A decision‐analytic model was developed to estimate the cost‐effectiveness of six management strategies in individuals initiating ART in the REALITY trial countries. Strategies included standard‐prophylaxis, enhanced‐prophylaxis, standard‐prophylaxis with fluconazole; and three CrAg testing strategies, the first stratifying individuals to enhanced‐prophylaxis (CrAg‐positive) or standard‐prophylaxis (CrAg‐negative), the second to enhanced‐prophylaxis (CrAg‐positive) or enhanced‐prophylaxis without fluconazole (CrAg‐negative) and the third to standard‐prophylaxis with fluconazole (CrAg‐positive) or without fluconazole (CrAg‐negative). The model estimated costs, life‐years and quality‐adjusted life‐years (QALY) over 48 weeks using three competing mortality risks: cryptococcal meningitis; tuberculosis, serious bacterial infection or other known cause; and unknown cause. Results Enhanced‐prophylaxis was cost‐effective at cost‐effectiveness thresholds of US$300 and US$500 per QALY with an incremental cost‐effectiveness ratio (ICER) of US$157 per QALY in the CD4 <200 cells/mm3 population providing enhanced‐prophylaxis components are sourced at lowest available prices. The ICER reduced in more severely immunosuppressed individuals (US$113 per QALY in the CD4 <100 cells/mm3 population) and increased in all individuals regardless of CD4 count (US$722 per QALY). Results were sensitive to prices of the enhanced‐prophylaxis components. Enhanced‐prophylaxis was more effective and less costly than all CrAg testing strategies as enhanced‐prophylaxis still conveyed health gains in CrAg‐negative patients and savings from targeting prophylaxis based on CrAg status did not compensate for costs of CrAg testing. CrAg testing strategies did not become cost‐effective unless the price of CrAg testing fell below US$2.30. Conclusions The REALITY enhanced‐prophylaxis package in individuals with advanced HIV starting ART reduces morbidity and mortality, is practical to administer and is cost‐effective. Efforts should continue to ensure that components are accessed at lowest available prices

Late Presentation With HIV in Africa: Phenotypes, Risk, and Risk Stratification in the REALITY Trial.

This article has been accepted for publication in Clinical Infectious Diseases Published by Oxford University PressBackground: Severely immunocompromised human immunodeficiency virus (HIV)-infected individuals have high mortality shortly after starting antiretroviral therapy (ART). We investigated predictors of early mortality and "late presenter" phenotypes. Methods: The Reduction of EArly MortaLITY (REALITY) trial enrolled ART-naive adults and children ≥5 years of age with CD4 counts .1). Results: Among 1711 included participants, 203 (12%) died. Mortality was independently higher with older age; lower CD4 count, albumin, hemoglobin, and grip strength; presence of World Health Organization stage 3/4 weight loss, fever, or vomiting; and problems with mobility or self-care at baseline (all P < .04). Receiving enhanced antimicrobial prophylaxis independently reduced mortality (P = .02). Of five late-presenter phenotypes, Group 1 (n = 355) had highest mortality (25%; median CD4 count, 28 cells/µL), with high symptom burden, weight loss, poor mobility, and low albumin and hemoglobin. Group 2 (n = 394; 11% mortality; 43 cells/µL) also had weight loss, with high white cell, platelet, and neutrophil counts suggesting underlying inflammation/infection. Group 3 (n = 218; 10% mortality) had low CD4 counts (27 cells/µL), but low symptom burden and maintained fat mass. The remaining groups had 4%-6% mortality. Conclusions: Clinical and laboratory features identified groups with highest mortality following ART initiation. A screening tool could identify patients with low CD4 counts for prioritizing same-day ART initiation, enhanced prophylaxis, and intensive follow-up.

External auditory canal leech: a rare case report of paediatric external auditory canal haemorrhage

Leeches are blood sucking organism feed on human blood. While human bites are common, they rarely cause human internal infestation. We describe a rare case of a parasitic leech infestation of the External Auditory Canal (EAC).A two month old child presented to the Emergency department with a seven day history of left sided ear bleeding. On examination she was noted to have a whitish foreign body in the left EAC imbedded in fresh blood. Irrigation with warm saline extracted a 1.5 cm long leech. While very uncommon, parasitic infestation should be considered in a patient living in the tropic

Hearing impairment and deafness among HIV infected children and adolescents in Harare, Zimbabwe.

Background: Among HIV-infected children ear infections are recurrent and chronic, which may lead to hearing loss. Objective: To determine the prevalence, cause and severity of hearing impairment among HIV-infected children aged 5-17 years attending for HIV care in Harare. Design and Setting: An analytical cross-sectional survey conducted at Newlands Clinic, an opportunistic infections clinic in Harare. Materials and Methods: Participants underwent a standardised otoscopic examination of the ear and Pure Tone Audiometry (PTA). Factors associated with hearing impairment were investigated using multivariate logistic regression. Results: Three hundred and eighty (380) participants (55% female and mean age 11 years (SD: 3.3 years)) were consecutively recruited. The vast majority of participants (n=338; 89% were taking antiretroviral therapy (ART) for a median of 3 (IQR: 2-5) years at recruitment, and the most recent median CD4 Count (i.e. CD4 count measured within 6 months of the study recruitment) was 725 (IQR: 497-1000) cells/µL, with no difference by ART status. 61% (n= 231) of participants had an abnormal ear examination. Of the 359 participants who underwent audiometry, the prevalence of hearing impairment was 32.3% (95%CI: 27.5%-37.4%) based on a PTA threshold ≥26Db. Hearing impairment was associated with a recent CD4 count <350cell/µL (OR 2.1, P<0.037). Conclusion: There is a high prevalence of hearing impairment among HIV-infected children and adolescents. Low CD4 count remains a risk factor even among those who are on ART. We recommend that HIV infected children and adolescents, particularly those with low CD4 counts, should have routine evaluation of hearing as part of HIV care
