BACKGROUND

Human immunodeficiency virus (HIV) infection increases the prevalence of QTc prolongation (QTc), which is an independent factor of cardiovascular disease events in this population. In the world literature this change is associated with the use of the protease inhibitors and efavirenz antiretrovirals. However, no data are available on these changes in the Mexican population.

MATERIAL AND METHOD

A prospective observational study was done selecting records from March 2015 to May 2016 of the external consultation of the National Institute of Respiratory Diseases (INER), Mexico City; they were divided into two groups, those without treatment, because recent diagnosis, and with antiretroviral treatment. We recorded clinical data, pharmacological treatment, electrocardiogram and blood chemistry.

RESULTS

We found no differences between the two groups regarding age or serum electrolytes. We found no association between QTc prolongation and efavirenz or protease inhibitors. Raltegravir decreased QTc duration (p = 0.001) while molluscum contagiosum coinfection was associated with QTc prolongation (p = 0.02).

CONCLUSION

In our study, we failed to demonstrate in Mexican population association of QTc prolongation with first- and second-line antiretrovirals. More studies are needed to determine the clinical significance of the effect of raltegravir and molluscum contagiosum on QTc.
