In conjunction with BMJ Case Reports, DTB will feature occasional drug-related cases that are likely to be of interest to readers. These will include cases that involve recently marketed drugs for which there is limited knowledge of adverse effects and cases that highlight unusual reactions to drugs that have been marketed for several years.

SUMMARY

Highly active antiretroviral therapy (HAART) has dramatically lowered rates of mother-to-child HIV transmission among patients with access to treatment. Barriers to complete viral suppression increase rates of transmission, even with only low levels of viral replication. Here, we present the case of a pregnant patient who developed a detectable viral load in pregnancy, thought to be related to calcium supplement consumption or emesis while using a dolutegravir-based HAART regimen. Ultimately, with adjustments, the patient again reached an undetectable viral load and had an uncomplicated perinatal and neonatal outcome. We discuss new data on the use of dolutegravir in pregnancy and precautions for maintaining viral suppression while on antiretroviral therapy in pregnancy.

Background

The advent of, and access to, highly active antiretroviral therapy (HAART) has revolutionised HIV care and restored near-normal life expectancy. The use of optimal active antiretroviral therapy (ART) can reduce mother-to-child transmission (MTCT) rate from 15%–30% to less than 0.5%.1 2 Optimal therapy requires initiation of ART prior to pregnancy, adherence throughout pregnancy, abstaining from breastfeeding and an undetectable viral load near time of delivery; even a modest elevation in viral load (50–399 copies per mL (cpm), compared with <50) is associated with a 22-fold increase in the rate of transmission.2 Here, we describe a patient who developed an elevated HIV viral load in pregnancy, thought …
