Introduction: Severe COVID-19 pneumonia has two phases that are not
mutually exclusive. Repurposed drugs target only one phase and the
association of combination therapy to survival is unknown.
Objective: To determine the association of hydroxychloroquine, azithromycin,
and methylprednisolone versus methylprednisolone only to in hospital survival.
Methods: This is a secondary analysis of a retrospective cohort of patients
admitted for severe covid-19 in 13 hospitals in New Jersey, United States from
March–June 2020. Propensity score match with 11 variables was constructed
between those who received no methylprednisolone and methylprednisolone.
Multivariate Cox regression was used for risk of in hospital mortality.
Measurements and main results: There were 759 patients, 380 in no
methylprednisolone and 379 with methylprednisolone. Multivariate Cox
regression shows that methylprednisolone, hydroxychloroquine, and
azithromycin had prolonged survival compared to methylprednisolone alone
[HR 0.45 (95% CI 0.22,0.91 p < 0.03)]. In patients who received
hydroxychloroquine and azithromycin, those who also received high dose
methylprednisolone were associated with worse survival compared to those
who received low dose methylprednisolone (HR = 1.642; 95% CI 1.053 to 2.562;
p = 0.0287). Nursing home residents [HR 2.77 (95% CI 1.67, 4.59 p < 0.0001)],
coronary artery disease [HR 2.93 (95% CI 1.31, 3.15 p = 0.001), and invasive
mechanical ventilation [HR 3.02 (95% CI 1.71,5.34 p = 0.0001)] were
independently associated with worse survival.
