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.
