Abstract
SETTING:
Drug resistance threatens tuberculosis (TB) control, particularly among human immunodeficiency virus (HIV) infected persons.

OBJECTIVE: To describe practices in the prevention and management of drug-resistant TB under antiretroviral therapy (ART) programs in lower-income countries.

DESIGN: We used online questionnaires...

Abstract
OBJECTIVES:
The aim of the study was to statistically model the relative increased risk of cardiovascular disease (CVD) per year older in Data collection on Adverse events of anti-HIV Drugs (D:A:D) and to compare this with the relative increased risk of CVD per year older in general population risk equations.

METHODS: We analysed three endpoints:...

Abstract
OBJECTIVES:
To evaluate the carotid intima-media thickness (cIMT) in perinatally HIV-infected adolescents and factors associated with cardiovascular abnormalities.

DESIGNS: A cross-sectional study was conducted in perinatally HIV-infected adolescents who had no known cardiovascular condition and healthy controls.

METHODS:...

Abstract
BACKGROUND:
Antiretroviral therapy (ART) has evolved rapidly since its beginnings. This analysis describes trends in first-line ART use in Asia and their impact on treatment outcomes.
METHODS: Patients in the TREAT Asia HIV Observational Database receiving first-line ART for ≥ 6 months were included. Predictors of treatment failure and treatment modification...

Abstract
OBJECTIVE:

To evaluate the value of time-updated weight and height in predicting clinical progression, immunological and virological failure in children receiving combination antiretroviral therapy (cART).

METHODS:
We used Cox regression to analyse data of a cohort of Asian children.

RESULTS:
2608 children were...

Abstract

OBJECTIVES:
The aim of the study was to assess the significance of low-level viraemia (LLV) and the timing of treatment change in low/middle-income country (L/MIC) compared with high-income country (HIC) settings.

METHODS: Patients with virological control following commencement of combination antiretroviral therapy (cART) were included in the study...

Abstract
INTRODUCTION:
First-line antiretroviral therapy (ART) failure often results from the development of resistance-associated mutations (RAMs). Three patterns, including thymidine analogue mutations (TAMs), 69 Insertion (69Ins) and the Q151M complex, are associated with resistance to multiple-nucleoside reverse transcriptase inhibitors (NRTIs) and may compromise treatment options for...

Abstract
BACKGROUND:
There are limited data on opportunistic infections (OI) and factors associated with their occurrence after highly active antiretroviral therapy (HAART) in Asian children. The use of HAART in Asia started much later than in developed countries and therefore reported findings may not be fully applicable to the pediatric HIV epidemic in Asia.

METHODS:...

Abstract
OBJECTIVES:
Regimens sparing RATE (ritonavir, abacavir, tenofovir, efavirienz) agents might have better long-term safety. We conducted a feasibility exercise to assess the potential for a randomised trial evaluating RATE-sparing regimens.

DESIGN: Observational.

METHODS: We first calculated RATE-sparing options available to an...

Abstract
INTRODUCTION:
Adherence to antiretroviral therapy (ART) plays an important role in treatment outcomes. It is crucial to identify factors influencing adherence in order to optimize treatment responses. The aim of this study was to assess the rates of, and factors associated with, suboptimal adherence (SubAdh) in the first 24 months of ART in an Asian HIV cohort.

...

Abstract
BACKGROUND:
We compared treatment outcomes of transmitted drug resistance (TDR) in patients on fully or partially sensitive drug regimens.

METHODS: Factors associated with survival and failure were analyzed using Cox proportional hazards and discrete time conditional logistic models.

RESULTS: TDR, found in 60 (4.1%) of 1471...

Abstract
BACKGROUND:
Recent studies suggest higher cumulative HIV viremia exposure measured as viremia copy-years (VCY) is associated with increased all-cause mortality. The objectives of this study are (1) report the association between VCY and all-cause mortality and (2) assess associations between common patient characteristics and VCY.

METHODS: Analyses were...

Abstract
BACKGROUND:
There have been improvements in combination antiretroviral therapy (cART) over the last 15 years. The aim of this analysis was to assess whether improvements in ART have resulted in improvements in surrogates of HIV outcome.

METHODS: Patients in the Australian HIV Observational Database who initiated treatment using mono/duo therapy prior to...

Abstract

BACKGROUND:
The aims of this study were to investigate the cancer incidence and risk in HIV/AIDS patients relative to the general population in Taiwan.

METHODS: Using Taiwan's National Health Insurance Research Database, 15,269 HIV/AIDS patients were identified between 1998 and 2009. Gender-specific incidence densities (IDs) of both AIDS-defining...

Abstract
BACKGROUND:
More perinatally HIV-infected children in Asia are reaching adolescence.

METHODS: We analyzed data from July 1991 to March 2011 reported by 18 clinics in 6 countries of children age >12 years.

RESULTS: Of 1254 adolescents, 33 (2.6%) died, and 52 (4.1%) were lost to follow-up within 2.4-year (3566 person-years)...

Abstract
BACKGROUND:
No consensus exists on how to define abnormally rapid deterioration in renal function (Rapid Progression, RP). We developed an operational definition of RP in HIV-positive persons with baseline estimated glomerular filtration rate (eGFR) >90 ml/min/1.73 m2 (using Cockcroft Gault) in the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D)...

Abstract
Introduction: Although antiretroviral therapy (ART) has been rapidly scaled up in Asia, most HIV-positive patients in the region still present with late-stage HIV disease. We aimed to determine trends of pre-ART CD4 levels over time in Asian HIV-positive patients and to determine factors associated with late ART initiation.Methods: Data from two regional cohort observational...

Abstract
OBJECTIVES:
We evaluated the effect of the time interval between the initiation of antiretroviral therapy (ART) and the initiation of tuberculosis (TB) treatment on clinical outcomes in HIV/TB-coinfected patients in an Asian regional cohort.

METHODS: Adult HIV/TB-coinfected patients in an observational HIV-infected cohort database who had a known date of...

Abstract

BACKGROUND:
Rates of suicide and accidental or violent death remain high in HIV-positive populations despite significantly improved prognosis since the introduction of cART.

METHODS: We conducted a nested case-control study of suicide and accidental or violent death in the Australian HIV Observational Database (AHOD) between January 1999 and March...

Abstract
INTRODUCTION:
Magnitude and frequency of HIV viral load blips in resource-limited settings, has not previously been assessed. This study was undertaken in a cohort from a high income country (Australia) known as AHOD (Australian HIV Observational Database) and another cohort from a mixture of Asian countries of varying national income per capita, TAHOD (TREAT Asia HIV Observational...

OBJECTIVES: Whilst several antiretroviral drugs have been associated with moderate chronic kidney disease (CKD), their contribution to advanced CKD and end-stage renal disease (ESRD) remain unknown.

DESIGN: D:A:D participants with at least three estimated glomerular filtration rates (eGFR) after February 2004 were followed until the first of advanced CKD (confirmed...

OBJECTIVE: To describe the CD4 cell count at the start of combination antiretroviral therapy (cART) in low-income (LIC), lower middle-income (LMIC), upper middle-income (UMIC), and high-income (HIC) countries.

METHODS: Patients aged 16 years or older starting cART in a clinic participating in a multicohort collaboration spanning 6 continents (International...
