[Is it possible to reduce the delay in diagnosing HIV infection?]

Mortality, Causes of Death and Associated Factors Relate to a Large HIV Population-Based Cohort

INTRODUCTION

Antiretroviral therapy has led to a decrease in HIV-related mortality and to the emergence of non-AIDS defining diseases as competing causes of death. This study estimates the HIV mortality rate and their risk factors with regard to different causes in a large city from January 2001 to June 2013.

MATERIALS AND METHODS

We followed-up 3137 newly diagnosed HIV non-AIDS cases. Causes of death were classified as HIV-related, non-HIV-related and external. We examined the effect of risk factors on survival using mortality rates, Kaplan-Meier plots and Cox models. Finally, we estimated survival for each main cause of death groups through Fine and Gray models.

MORTALITY RESULTS

182 deaths were found [14.0/1000 person-years of follow-up (py); 95% confidence interval (CI):12.0-16.1/1000 py], 81.3% of them had a known cause of death. Mortality rate by HIV-related causes and non-HIV-related causes was the same (4.9/1000 py; CI:3.7-6.1/1000 py), external was lower [1.7/1000 py; (1.0-2.4/1000 py)].

SURVIVAL RESULTS

Kaplan-Meier estimate showed worse survival in intravenous drug user (IDU) and heterosexuals than in men having sex with men (MSM). Factors associated with HIV-related causes of death include: IDU male (subHazard Ratio (sHR):3.2; CI:1.5-7.0) and <200 CD4 at diagnosis (sHR:2.7; CI:1.3-5.7) versus ≥500 CD4. Factors associated with non-HIV-related causes of death include: ageing (sHR:1.5; CI:1.4-1.7) and heterosexual female (sHR:2.8; CI:1.1-7.3) versus MSM. Factors associated with external causes of death were IDU male (sHR:28.7; CI:6.7-123.2) and heterosexual male (sHR:11.8; CI:2.5-56.4) versus MSM.

CONCLUSION AND RECOMMENDATION

There are important differences in survival among transmission groups. Improved treatment is especially necessary in IDUs and heterosexual males.

[Promoting routine human immunodeficiency virus testing in primary care]

OBJECTIVES

To promote human immunodeficiency virus (HIV) testing in the primary care setting and to describe patients' attitudes toward this practice.

METHODS

A non-randomized intervention was conducted on five physicians of an urban primary care center attending patients aged 18-65 years old, who were scheduled to undergo blood tests for other reasons. The patients were systematically offered HIV blood testing if they reported having had sex without a condom with a person of unknown HIV status. Not being tested required active refusal. The intervention period was from October to December 2008 and the control period was from October to December 2007. The main variable was the difference in the number of HIV tests requested. The proportion of patients accepting the test was also analyzed.

RESULTS

Demographic factors were similar in patients in the two periods. The number of HIV tests increased from 3.7% (22/599) to 27.2% (212/780), p <0.001. A total of 209 patients were offered the HIV test. Their mean age was 45.6 years (SD 11.7), 141 were women (68%) and 11 were born outside Spain (5%). One hundred and ninety-five patients (93%) admitted the possibility of having been or being at risk. Of these patients, only three (1.5%), refused the HIV test.

CONCLUSIONS

Routine HIV testing in the primary care setting is feasible and few patients refuse to be tested.
