HCQ for COVID-19

1st treatment shown to reduce risk in March 2020

^*, now known with p < 0.00000000001 from 422 studies, recognized in 42 countries.

Lower risk for mortality, hospitalization, recovery, cases, and viral clearance.

No treatment is 100% effective. Protocols combine complementary and synergistic treatments. ^* >10% efficacy in meta analysis with ≥3 clinical studies.

4,100+ studies for 60+ treatments. c19hcq.org

Retrospecttive 220 COVID-19 patients with rheumatic disease in Japan, showing lower mortality and hospitalization with HCQ prophylaxis, without statistical significance.

Study covers remdesivir and HCQ.

risk of death, 92.2% lower, RR 0.08, p = 1.00, treatment 0 of 14 (0.0%), control 11 of 206 (5.3%), NNT 19, unadjusted, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).

risk of hospitalization, 11.5% lower, RR 0.88, p = 0.34, treatment 9 of 14 (64.3%), control 177 of 206 (85.9%), NNT 4.6, adjusted per study, odds ratio converted to relative risk, multivariable.

Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

Background: The incidence and prognosis of COVID-19 and rheumatic disease vary among ethnicities and regions. COVID-19 outcomes in rheumatic disease patients remain unclear, especially in the Asia-Pacific region. This study aimed to clarify the demographic and clinical factors that may influence COVID-19 prognosis in rheumatic disease patients.

Conflict of interest K. Oku, Y. Kimoto, T. Horiuchi, M. Yamamoto, Y. Kondo, M. Okamoto, and Tatsuya Atsumi have no conflicts of interest to declare. T.Takeuchi has received a speaking fee from Eli Lilly Japan K.K., and a research grant from Chugai Pharmaceutical Co.
