Given the speed of evolution of the epidemic and the permanent information needs of the scientific community, combined with the difficulty of travel, the IHU has decided to put online the submitted articles (preprint), as have already started to do the sites but which in the current situation have deadlines too important to be compatible with the need for speed that we have.
All their publications they will submit, will be put in preprint on their site and will be replaced by a link to an official scientific publication, as soon as these articles are accepted and in their final form.
They hope that this will allow scientists around the world to follow our work in this epidemic situation.
LATEST TEST RESULTS
In a recent survey, most physicians worldwide considered that hydroxychloroquine (HCQ) and azithromycin (AZ) are the two most effective drugs among available molecules against COVID-19. Nevertheless, to date, one preliminary clinical trial only has demonstrated its efficacy on the viral load. Additionally, a clinical study including 80 patients was published, and in vitro efficiency of this association was demonstrated.
The study was performed at IHU Méditerranée Infection, Marseille, France. A cohort of 1061 COVID-19 patients, treated for at least 3 days with the HCQ-AZ combination and a follow-up of at least 9 days was investigated. Endpoints were death, worsening and viral shedding persistence.
From March 3rd to April 9th, 2020, 59,655 specimens from 38,617 patients were tested for COVID-19 by PCR. Of the 3,165 positive patients placed in the care of our institute, 1061 previously unpublished patients met our inclusion criteria. Their mean age was 43.6 years old and 492 were male (46.4%). No cardiac toxicity was observed. A good clinical outcome and virological cure was obtained in 973 patients within 10 days (91.7%). Prolonged viral carriage at completion of treatment was observed in 47 patients (4.4%) and was associated to a higher viral load at diagnosis (p < 10-2 ) but viral culture was negative at day 10 and all but one were PCR-cleared at day 15. A poor outcome was observed for 46 patients (4.3%); 10 were transferred to intensive care units, 5 patients died (0.47%) (74-95 years old) and 31 required 10 days of hospitalization or more. Among this group, 25 patients are now cured and 16 are still hospitalized (98% of patients cured so far). Poor clinical outcome was significantly associated to older age (OR 1.11), initial higher severity (OR 10.05) and low 2 hydroxychloroquine serum concentration. In addition, both poor clinical and virological outcomes were associated to the use of selective beta-blocking agents and angiotensin II receptor blockers (P<0.05). Mortality was significantly lower in patients who had received > 3 days of HCQ-AZ than in patients treated with other regimens both at IHU and in all Marseille public hospitals (p< 10-2 ). Interpretation The HCQ-AZ combination, when started immediately after diagnosis, is a safe and efficient treatment for COVID-19, with a mortality rate of 0.5%, in elderly patients. It avoids worsening and clears virus persistence and contagiosity in most cases.
