Impact of highly active antiretroviral therapy (HAART) on AIDS and death in a cohort of vertically HIV type 1-infected children: 1980-2006

How Far Does Highly Active Antiretroviral Treatment Reduce TB Incidence among Children? A Marginal Structural Modeling Analysis, Southwest Ethiopia

Background

Children younger than 15 years, carry almost 80% of the global burden of HIV/AIDS. HIV worsens the progression of latent TB to active TB disease. Although antiretroviral treatment has shown marked reduction in Tuberculosis incidence, TB continues to occur in Sub-Saharan countries including Ethiopia. The aim of this study was to investigate the impact of HAART on the incidence of tuberculosis among children infected with HIV in Southwest Ethiopia.

Methods

A retrospective cohort study was conducted between 2009 to 2014. We used chi-square test, and Mann-Whitney U test to compare non-HAART and HAART cohort. We estimated the effect of HAART on TB incidence using marginal structural model after adjusting for time-dependent confounders affected by exposure.

Result

A total of 844 children were followed. We observed them for a median of 51 months (IQR 31) and a total of 2942.99 child-years. The overall TB incidence rate was 7.917 per 100 child years (95% CI, 6.933–9.002). TB incidence for specific HAART and non-HAART cohort were 7.67 per 100 child-years (95% CI, 6.318–9.217) and 8.17 per 100 child-years (95% CI, 6.772–9.767) respectively. From marginal structural modeling, children on HAART were 36% (HR=0.642, 95% CI 0.442–0.931, p<0.02) less likely to develop TB compared to those who were not.

Conclusion

HAART reduced the hazard of TB in HIV-infected children by 36%. This is by far less than what is expected.

Effect of highly active antiretroviral treatment on TB incidence among HIV infected children and their clinical profile, retrospective cohort study, South West Ethiopia

Globally, 1.8 million HIV infected children live with HIV; nearly 53% of them were receiving HIV treatment. People who are infected with HIV are 18 times more likely to develop active TB. Despite antiretroviral treatment has shown marked reduction in TB incidence, TB continues to occur in Sub-Saharan countries including Ethiopia among HIV infected people. The effect of highly active antiretroviral treatment is quite successful in developed countries. However, in developing country TB/HIV co-infection remains perplexing among children on the treatment. The aim of this study was to investigate the impact of ART on the incidence of TB among Children infected with HIV in Southwest Ethiopia. A retrospective cohort study was conducted on randomly selected 800 samples from ART clinic between 2009 and 2014. We used chi-square test, and Mann–Whitney U test to compare HAART naïve and HAART cohort. We used marginal structural models to estimate the effect of HAART on survival while accounting for time-dependent confounders affected by exposure. A total of 800 children were followed for 2942.99 child-years. The children were observed for a median of 51 months with IQR 31 and for a total of 2942.99 child-years. From 506 OIs that occurred, the most common reported OIs were Pneumonia (22%) and TB (23.6%). The overall TB incidence rate was 7.917 per 100 child years (95% CI, 6.933–9.002). Whereas among HAART (7.667 per 100-years (95% CI, 6.318–9.217) and 8.1686 per 100 person-years (95% CI 6.772–9.767) for HAART naïve. The mortality hazard ratio comparing HAART with no HAART from a marginal structural model was 0.642 (95% CI 0.442–0.931, p < 0.02). HAART reduced the hazard of TB in HIV-infected children by 36%. This is by far less than expected.

Community beliefs, HIV stigma, and depression among adolescents living with HIV in rural Uganda

The availability of and increased access to antiretroviral therapy (ART) has significantly reduced the morbidity and mortality associated with HIV. As a result, perinatally infected youth are increasingly able to reach adolescence. There is limited information about the psychosocial challenges facing adolescents living with HIV (ALWH) in rural settings of sub-Saharan Africa. We sought to understand psychosocial challenges facing ALWH in rural Uganda and their effects on mental health and HIV treatment outcomes. We conducted 5 focus group discussions and 40 one-on-one in-depth interviews in Mbarara, Uganda with adolescents (aged 13-17 years) and adult women caregivers. All interviews were audio-recorded, transcribed directly into English, and coded using thematic analysis to identify themes related to psychosocial adversities and mental health. Adversities faced by adolescents included negative community perceptions (perceived aggression, presumed early mortality), HIV stigma (enacted and internalized), vulnerability factors (loss of parents, poverty), and health challenges (depression, ART non-adherence). In the conceptual model that emerged from the findings, negative community perceptions (about perceived aggression or presumed early mortality) predisposed ALWH to experience enactments and internalization of stigma that led to depression and ART non-adherence. The data also identified several protective factors, including counselling, family and religious support, and timely serostatus disclosure. Interventions to correct community misperceptions about HIV can potentially reduce stigma and thereby improve physical and mental health outcomes of ALWH.

Paediatric HIV-1 infection: updated strategies of prevention mother-to-child transmission

INTRODUCTION

HIV-1 epidemiology is changing and prevention of mother-to-child transmission (PMTCT) strategies have been continuously optimized over time. However, the correct management of infected women during pregnancy is crucial for PMTCT and cases of vertical transmission continue to occur.

OBJECTIVE

To review the most recent evidence regarding the prevention of MTCT in resource-rich and resource-limited settings, focalizing on new possible approaches.

RESULTS

New issues regard the optimal antiretroviral therapy regimen for pregnant women with good immunological control, the use of intrapartum zidovudine (ZDV) in pregnant women with low viral load, the optimization of prophylaxis in the settings where breastfeeding is recommended and use of combined neonatal prophylaxis (CNP) in infants at high-risk for MTCT. Complete viral control, in recent years, has been achieved in most infected pregnant women, has led to change the recommended mode of delivery, since vaginal birth has become a safe option and is now largely recommended. Recent data reported a large use of CNP in preterm infants: this practice may be dangerous, due to the lack of safety data, and its efficacy and effectiveness is unproven.

CONCLUSION

Data are accumulating on efficacy, effectiveness and safety of different PMTCT strategies in various possible clinical scenarios, however further researches are needed in order to optimize the management of infants at extremely low risk for MTCT as well as in those presenting with high risk for infection.

Interruption of cART in clinical practice is associated with an increase in the long-term risk of subsequent immunosuppression in HIV-1-infected children

BACKGROUND

Antiretroviral treatment interruption (TI) is not recommended in HIV-infected children. We aimed to evaluate the context and consequences of TI in clinical practice.

METHODS

We investigated the probability and risk factors of a first TI in the 483 children treated with combined ART (cART) in the ANRS French national pediatric cohort. Immunologic and virologic outcomes were compared between patients with TI (TI group) and those on continuous treatment (matched control group), from a baseline defined as the age at first interruption for the TI child and the corresponding age for the control child.

RESULTS

At least one TI ≥ 3 months occurred in 42.4% of patients, at a median age of 8.0 years, for a median duration of 12.1 months. After cART initiation, the risk of TI was 7.0% (5.0-9.6) at 1 year and 30.3% (26.1-35.0) at 5 years and was higher for children starting treatment before 2000 and for children starting cART before 6 months of age. AIDS-free survival was similar, but severe immunosuppression occurred earlier in the TI group than in the control group (adjusted HR = 3.1; 1.0-9.1; P = 0.04). Four years after baseline, the proportion of patients with CD4% ≥ 25% was lower in the TI group than in the control group (52.0% vs. 72.0%; P < 0.01), even among children restarting cART at least 6 months earlier (aRR = 0.5; 0.3-0.9; P = 0.03).

CONCLUSIONS

The risk of TI in clinical practice has decreased but remains high. In intent-to-treat analysis, TI was associated with a greater risk of subsequent immunosuppression, even after cART resumption.

Determinants of highly active antiretroviral therapy duration in HIV-1-infected children and adolescents in Madrid, Spain, from 1996 to 2012

OBJECTIVES

To investigate the duration of sequential HAART regimens and predictors of first-line regimen discontinuation among HIV-1 vertically infected children and adolescents.

DESIGN

Multicentre survey of antiretroviral-naïve patients enrolled in the HIV-Paediatric Cohor,t CoRISpeS-Madrid Cohort, Spain.

METHODS

Patients with a follow-up of ≥ 1 month spent on HAART, with available baseline CD4 count and HIV-viral load (VL) were included. Time spent on sequential HAART regimens was estimated and multivariable regression was used to identify predictors of time to first-line regimen discontinuation.

RESULTS

104 patients were followed for a median 8 years after starting HAART among 1996-2012; baseline %CD4 was 21.5 (12.3-34.0)and viral load was 5.1 (4.6-5.6) log10 copies/mL. Patients received a mean of 1.9 regimens. Median time on first-line HAART (n = 104) was 64.5 months; second HAART (n = 56) 69.8 months; and third HAART (n = 21) 66.5 months. Eleven (11%) patients were lost to follow-up while on first-line HAART and 54% discontinued (cumulative incidence of 16% and 38% by 1 and 3-year, respectively). The main predictor of first-line regimen discontinuation was suboptimal adherence to antiretrovirals (AHR: 2.60; 95% CI: 1.44-4.70).

CONCLUSIONS

Adherence to therapy was the main determinant of the duration of the first-line HAART regimen in children. It is important to identify patients at high risk for non-adherence, such as very young children and adolescents, in provide special care and support to those patients.

Late-stage diagnosis of HIV infection in Brazilian children: evidence from two national cohort studies

This study analyzed data from two consecutive retrospective cohort samples (1983 to 1998 and 1999 to 2002) of Brazilian children with AIDS (N = 1,758) through mother-to-child-transmission. Late-stage diagnosis (CDC category C) was investigated in relation to the following variables: year of birth, year of HIV diagnosis, and time periods related to changes in government treatment guidelines. Late-stage diagnosis occurred in 731 (41.6%) of cases and was more prevalent in infants under 12 months of age. The rate of late-stage diagnosis decreased from 48% to 36% between the two periods studied. We also observed a reduction in the proportion of late-stage diagnoses and the time lapse between HIV diagnosis and ART initiation. A significant association was found between timely diagnosis and having been born in recent years (OR = 0.62; p = 0.009) and year of HIV diagnosis (OR = 0.72; p = 0.002/OR = 0.62; p < 0.001). Infants under the age of 12 months were more likely to be diagnosed at a late stage than older children (OR = 1.70; p = 0.004). Despite advances, there is a need to improve the effectiveness of policies and programs focused on improving early diagnosis and management of HIV/AIDS.

Living situation affects adherence to combination antiretroviral therapy in HIV-infected adolescents in Rwanda: a qualitative study

Introduction

Adherence to combination antiretroviral therapy (cART) is vital for HIV-infected adolescents for survival and quality of life. However, this age group faces many challenges to remain adherent. We used multiple data sources (role-play, focus group discussions (FGD), and in-depth interviews (IDI)) to better understand adherence barriers for Rwandan adolescents. Forty-two HIV positive adolescents (ages 12–21) and a selection of their primary caregivers were interviewed. All were perinatally-infected and received (cART) for ≥12 months. Topics discussed during FGDs and IDIs included learning HIV status, disclosure and stigma, care and treatment issues, cART adherence barriers.

Results

Median age was 17 years, 45% female, 45% orphaned, and 48% in boarding schools. We identified three overarching but inter-related themes that appeared to influence adherence. Stigma, perceived and experienced, and inadvertent disclosure of HIV status hampered adolescents from obtaining and taking their drugs, attending clinic visits, carrying their cARTs with them in public. The second major theme was the need for better support, in particular for adolescents with different living situations, (orphanages, foster-care, and boarding schools). Lack of privacy to keep and take medication came out as major barrier for adolescents living in congested households, as well the institutionalization of boarding schools where privacy is almost non-existent. The third important theme was the desire to be ‘normal’ and not be recognized as an HIV-infected individual, and to have a normal life not perturbed by taking a regimen of medications or being forced to disclose where others would treat them differently.

Conclusions

We propose better management of HIV-infected adolescents integrated into boarding school, orphanages, and foster care; training of school-faculty on how to support students and allow them privacy for taking their medications. To provide better care and support, HIV programs should stimulate caregivers of HIV-infected adolescents to join them for their clinic visits.

Antiretroviral use in Italian children with perinatal HIV infection over a 14-year period

BACKGROUND

Information on the use of new antiretroviral drugs in children in the real setting of clinical fields is largely unknown.

METHODS

Data from 2554 combined antiretroviral therapy (cART) regimens administered to 911 children enrolled in the Italian Register for HIV infection in children, between 1996 and 2009, were analysed. Factors potentially associated with undetectable viral load and immunological response to cART were explored by Cox regression analysis.

RESULTS

Proportion of protease inhibitor (PI)-based regimens significantly decreased from 88.0% to 51.2% and 54.9%, while proportion on non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens increased from 4.5% to 38.8% and 40.2% in 1996-1999, 2000-2004 and 2005-2009, respectively (p < 0.0001). Significant change in the use of each antiretroviral drug occurred over the time periods (p < 0.0001). Factors independently associated with virological and immunological success were as follows: later calendar periods, younger age at regimen (only for virological success) and higher CD4(+) T-lymphocyte percentage at baseline. Use of unboosted PI was associated with lower adjusted hazard ratio (aHR) of virological or immunological success with respect to NNRTI- and boosted PI-based regimens, with no difference among these two latter types.

CONCLUSION

Use of new generation antiretroviral drugs in Italian HIV-infected children is increasing. No different viro-immunological outcomes between NNRTI- and boosted PI-based cART were observed.

Safety and tolerability of antiretroviral therapy among HIV-infected children and adolescents in Uganda

BACKGROUND

Antiretroviral therapy (ART) is known to cause a number of adverse effects. The objective of this study was to determine the frequency and outcome of ART-related adverse events among patients aged 6 weeks to 18 years.

METHODS

We followed up a cohort of 378 HIV-infected children and adolescents who started ART at the Baylor-Uganda Clinic during the period July 2004 to July 2009. Patients were started on zidovudine or stavudine, plus lamivudine, and efavirenz or nevirapine. Adverse events were recorded as they occurred. Descriptive analyses and Kaplan-Meier survival analysis were carried out.

RESULTS

Of 126 adverse events reported among 107 (28.3%) patients, dizziness (17.5%), diarrhea (13.5%), and nausea and vomiting (14.3%) were the most frequent. Anxiety/night mares, skin rashes, nail discoloration, and lipodystrophy each contributed between 5% and 10%; whereas anorexia, abdominal pain, hepatitis, and somnolence contributed 1%-5%. Amnesia, lactic acidosis, gynaecomastia, cardiomyopathy, and peripheral neuropathy were rare, each contributing less than 1% of the total events. The overall probability of remaining free of adverse events was 77.1% (95% confidence interval: 72.38 to 81.13) at month 6 of ART.Among infants and young children, neurologic events could not be determined. Laboratory abnormalities were present at baseline and during follow-up, and hemoglobin levels increased significantly during the first 6 months of ART. There was no association between adverse events and baseline patient characteristics.

CONCLUSION

Close to one-third of children on ART experience adverse events. Most events occur within the first 3 months of ART and are not associated with baseline patient characteristics.

[Characteristics of human immunodeficiency virus-1 infected children receiving highly active antiretroviral therapy: a cross-sectional study]

INTRODUCTION

Since 1996, when HAART became available, there has been a change in the course of HIV-infection, leading it to become a chronic disease. Our aim was to describe the characteristics of the children followed up in our hospital.

PATIENTS AND METHODS

A cross-sectional study was conducted on 32 HIV-infected children followed up until December-2010, at the University-Hospital de Getafe. Clinical and laboratory information from the last visit was collected for the evaluation of patients.

RESULTS

Thirty-two children with HIV-1 were evaluated, 29 infected through vertical-transmission. The median age was 14 years. According to the CDC classification, 56% (18/32) of children were in category A, 28% (9/32) B and 16% (5/32) C. Immunological class was 3 in 75% of children, class 2 in 9% and class 1 in 16%. The median nadir of CD4 was 337 cells/ml (12%). The median current CD4 was 749 (31%). Only one adolescent had a CD4% below 200 cells/ml due to lack of adherence. Twenty-eight patients (87%) were receiving HAART, and 4 patients were off antiretroviral treatment. Among the patients treated, 26 (93%) had viral loads <200 copies/ml. The median viral-load was<20 copies/ml. Median time on antiretroviral treatment was 10 years. The combination more frequently used was two nucleoside reverse transcriptase inhibitors (NRTI) and one protease inhibitor (PI), that was given to 15 patients (47%), followed by 2 NRTI, and one non-nucleoside reverse transcriptase inhibitor (NNRTI) in 8 patients (29%). Two children received rescue therapy including raltegravir, one with tipranavir and the other with darunavir. A total of 12 patients (43%) received medication once a day, 7 of them with fixed-dose combinations in a single tablet (25%). There were metabolic complications, including hyperlipidaemia or lipodystrophy were observed in 17 children (53%).

CONCLUSIONS

Most of our patients are receiving HAART, with good virological and immunological control. The prevalence of metabolic abnormalities was high. Strategies to improve adherence and decrease toxicities are needed in perinatally-acquired HIV-infected children.

Abnormalities in body composition and nutritional status in HIV-infected children and adolescents on antiretroviral therapy

This cross-sectional study aimed to compare growth, nutritional status and body composition outcomes between a group of 94 HIV-infected children and adolescents on antiretroviral therapy (ART) and 364 healthy controls, and to evaluate their association with clinical and lifestyle variables within the HIV-infected group. When compared with the control group, HIV patients had higher risk of stunting (odds ratio [OR] 5.33, 95% confidence interval [CI]: 2.83-10.04) and thinness (OR 4.7, 95% CI: 2.44-9.06), higher waist-to-hip ratios (medians 0.89 versus 0.82 for boys and 0.90 versus 0.77 for girls, P < 0.001), and lower prevalence of overweight or obesity (OR 0.33, 95% CI: 0.14-0.78). Protease inhibitor usage was associated with thinness (OR 3.51, 95% CI 1.07-11.44) and lipoatrophy (OR 3.5, 95% CI 1.37-8.95). HIV-infected children on ART showed significant nutritional status and body composition abnormalities, consistent with the severity of vertical HIV infection and the consequences of prolonged ART.

Mortality in Brazilian children with HIV/AIDS: the role of non-AIDS-related conditions after highly active antiretroviral therapy introduction

AIDS-related mortality has been significantly reduced in areas that systematically adopted highly active antiretroviral therapy (HAART). In Brazil, despite advances in control policy, there is still a lack of evidence about trends in children on causes of death related or not related to HIV/AIDS. We evaluate temporal trends in mortality due to non-HIV-related causes of death in relation to HIV/AIDS-related conditions among children with and without HIV infection. This nationwide study included all deaths in children reported from 1999 to 2007. Mortality odds ratios (MOR) and rates were calculated to assess time trends of death in children with or without HIV/AIDS. These data were analyzed by calendar year, as obtained from official national database. A total of 680,763 deaths occurred in Brazilian children under 13 years of age; of these, 2191 (0.32%) had causes related to HIV/AIDS listed on the death certificate. The mortality rate from HIV/AIDS-related causes in Brazilian children ranged from 0.72 per 100,000 children in 1999 to 0.40 per 100,000 children in 2007, while for selected nonrelated causes the rate of death among HIV-infected children was stable at 0.08 per 100,000 Brazilian children. In children with HIV/AIDS, the MOR of having selected conditions unrelated to HIV/AIDS as a cause of death in 2007 (compared to 1999) was 1.85 (95% confidence interval [CI] = 1.11-3.08, p = 0.02), but without a significant temporal trend (p = 0.413) through the analyzed period. In Brazil, deaths related to HIV/AIDS mortality in children significantly decreased, while the unrelated causes in HIV-infected children maintained a stable trend. These data reinforce the success of national public health policies and the need to offer comprehensive care to children with HIV/AIDS.

AIDS morbidity and mortality in Brazilian children before and after highly active antiretroviral treatment implementation: an assessment of regional trends

BACKGROUND

The objective of this study was to analyze regional trends over time of acquired immunodeficiency syndrome (AIDS) cases and deaths in Brazilian children, before and after implementation of free access to highly active antiretroviral treatment (HAART).

METHODS

We performed a nation-wide study with an ecologic design and a time-series analysis of AIDS incidence and mortality rates in children (0-12 years of age), using polynomial regression models. Data were obtained from official national databases on age group, residence region, and year of AIDS diagnosis and death (1984-2008).

RESULTS

Between 1984 and 2008, 14,314 (2.7%) AIDS cases and 5041 deaths (2.3% of all AIDS-related deaths) were reported in Brazilian children. Incidence after 1996 was reduced by 23%, as compared with the pre-HAART era. The mortality rate observed in the HAART era was reduced by 63.6%. There was a significant reduction in the incidence in the Southeast and Central-West regions (P < 0.001), but the less industrialized North region showed an increase in the pre-HAART era (P < 0.001), and the Northeast region showed a stabilization trend (P < 0.001). In the South region, the incidence of AIDS increased in the 0 to 4 years subgroup. A reduction of AIDS mortality in the Southeast (P < 0.001), South, and Central-West regions (P < 0.001) was seen, but the Northeast and North regions maintained an increasing mortality trend (P < 0.001).

CONCLUSIONS

Despite the overall reduction in AIDS-related cases and deaths among children in Brazil since HAART, marked regional differences continue to exist. These reflect structural factors, different transmission dynamics, and operational issues. There is a need for improving the health service network with special emphasis on the less developed regions.

Opportunistic illnesses in Brazilian children with AIDS: results from two national cohort studies, 1983-2007

Background

HAART has significantly reduced AIDS-related morbidity in children. However, limited evidence is available from developing countries regarding patterns of opportunistic illnesses. We describe these events and their associated factors in children with AIDS in Brazil.

Methods

This study is based on two representative retrospective multi-center cohorts including a total 1,859 children with AIDS, infected via mother-to-child transmission (MTCT), between 1983-2002. Opportunistic illnesses were described and analyzed over time. The association of demographic, clinical and operational data with the occurrence of opportunistic diseases was assessed.

Results

In total, 1,218 (65.5%) had at least one event of an opportunistic disease. Variables significantly associated with occurrence of these events included: region of residence (OR 2.68-11.33, as compared to the Northern region), age < 1 year at diagnosis (OR 2.56, 95% CI 1.81-3.61, p < 0.001), and non-performance of MTCT prevention measures (OR 1.58, 95% CI 1.21-2.07, p < 0.001). Protective factors included year of HIV diagnosis in the HAART era (OR 0.34, 95% CI 0.15-0.76, p = 0.009) and ART use (OR 0.58, 95% CI 0.44-0.77, p < 0.001). In both periods bacterial infections represented the most common opportunistic events (58.6 vs. 34.7%; p < 0.001), followed by Pneumocystis jirovecii pneumonia (21.9 vs. 13.2%; p < 0.001), and bacterial meningitis/sepsis (16.8 vs. 7.4%; p < 0.001).

Conclusions

Despite the significant reduction in recent years, opportunistic illnesses are still common in Brazilian children with AIDS in the HAART era, especially bacterial diseases. The data reinforce the need for scaling up prevention of MTCT, early diagnosis of infection, and improvement of comprehensive pediatric care.

Causes of death in pediatric patients vertically infected by the human immunodeficiency virus type 1 in Madrid, Spain, from 1982 to mid-2009

BACKGROUND

Effective therapies have increased life expectancy of human immunodeficiency virus (HIV)-infected pediatric patients. We investigated the underlying causes of death, mortality, and acquired immune deficiency syndrome (AIDS) rates in HIV-infected pediatric patients in Madrid, Spain.

METHODS

We studied a multicenter cohort of 478 HIV-infected pediatric patients in Madrid. Mortality and AIDS incidence rates, causes of death, CD4 T-cell, and HIV RNA were analyzed during calendar periods (CPs): pre-HAART (highly active antiretroviral therapy) (CP1: 1982-1996) and post-HAART era (CP2: 1997-2009).

RESULTS

During 5690 person-years of follow-up 157 (32.8%) deaths occurred. Median age at death increased (CP1: 3.2 years [1.0-6.3] vs. CP2: 7.7 years [3.1-11.4]; P < 0.01). Mortality and AIDS rates decreased 10.6-fold (95% confidence intervals [CI]: 6.9-16.7) and 6.9-fold (95% CI: 5.0-9.6), respectively, between CPs. Nevertheless, mortality was 10.4-fold (95% CI: 5.8-18.8; P < 0.001) higher than in age-similar general population in late-CP2. In all, 169 causes of death were reported. Multiple causes were reported in 16 of 151 (10.6%) patients. In 81.1% (137/169), the causes were AIDS-defining, 11.8% (20/169) HIV-related, and 7.1% (12/169) non-HIV-related. Infections were the leading causes (60.8%, 101/166); from 1999 to 2007 the risk of death from infections was 115.9 times (95% CI: 42.0-265.8; P < 0.001) higher than in the age-similar general population. Comorbidity was reported in 66.9% (101/151) of patients. Median HIV-1 RNA at death decreased (CP1: 5.9 [5.0-6.3]; CP2: 5.3 [4.2-5.8]; P < 0.01).

CONCLUSIONS

Despite decline in mortality and AIDS rates, it is important to monitor all causes of death as prolonged survival might allow underlying comorbidity to become more clinically relevant.
