Conclusion:
A combination of SLE with hypocalcemia and pulmonary embolism in the
setting of COVID19 infection, while expected, has not been reported in
the literature. This can be alarming since patients with SLE are already
immunosuppressed with high risk of thrombosis. Adding the risk of
thrombosis from COVID19, this can result in a massive pulmonary embolism
as in our reported patient. Hence, in such patients, hypocalcemia should
be thoroughly investigated, properly addressed and adequately managed.
