Abstract

Coronavirus disease 2019 (COVID-19) leads to inflammatory cytokine release, which can downregulate the expression of metabolizing enzymes. This cascade affects drug concentrations in the plasma. We investigated the association between lopinavir (LPV) and hydroxychloroquine (HCQ) plasma concentrations and the levels of the acute-phase inflammation marker C-reactive protein (CRP). LPV plasma concentrations in 92 patients hospitalized at our institution were prospectively collected. Lopinavir-ritonavir was administered every 12 hours, 800/200 mg on day 1 and 400/100 mg on day 2 until day 5 or 7.

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Some limitations of this study should be acknowledged. We did not consider IL-6 measurement as a routine diagnostic value within our COVID-19 cohort, and hence, in study. IL-6 is a central mediator of the acute-phase response and a primary determinant of hepatic production of CRP. IL-6 has many other pathophysiologic roles in humans (42) and its diagnostic value for COVID-19, in particular for non-severe cases, is unknown. The selection of cutoff of 12 hours in the case of TCZ administration prior to measurement of LPV plasma concentrations was clinically reasonable but arbitrary. However, this limitation applied to only 3 patients, and had no statistical influence on the results. In conclusion, high LPV trough plasma concentrations were observed in COVID-19 patients. However, the calculated unbound concentrations in the lung indicates insufficient levels to inhibit SARS-CoV-2 replication. LPV levels correlated positively with CRP values and negatively with the preadministration of TCZ, indicating that COVID-19 related cytokine release significantly inhibits CYP3A4. Caution is advised when prescribing CYP3A4 substrates with a narrow therapeutic index to COVID-19 patients because of the risk of elevated drug levels and related toxicities.
