Understanding immunopathogenesis of COVID-19 is very important, not only in the management of complications, but also developing efficient treatment regimens. Why elderly adults with COVID-19 have poor treatment response and greater mortality than younger individuals? [2] . IL-6 is known to be potent mediator of inflammatory processes of elderly named Alzheimer disease. Improvement of dementia with cytotoxic treatment was reported in a case of Alzheimer disease. It has also been shown that decreased estrogen and testosterone level in elderly patient is unable to downregulate IL-6 gene expression [3] [4] [5] . Also, estrogen result in decrease pro-inflammatory cytokine IFN, IL-2, IL-6 TNF a production, and increased anti-inflammatory cytokine IL-4 and IL-5 production [6] . On the other hand, a variety of potantial anti-inflammatory agents are currently investigating in COVID-19. One of them is hydroxychloroquine via to inhibit immune response to the COVID-19 [1, 7] . It inhibits the production of TNF, IFNα, IL-6 and natural killer cell [8] [9] [10] . Moreover, co-medication of selective estrogen receptor modulatory with hydroxychloroquine is associated with eye toxicity due to synergistic inhibition of lysosomal enzymes [11] . Taken all together, it may be suggested that endogenous pro-inflamatory modulation agent (estrogen and testesteron) may be effective in management of elderly COVID-19 by decreasing pro-inflammatory cytokine. Also, doping administration of anabolizan steroids may slow progression of elderly COVID-19 with the effects mentioned above.
