"Beverly Hills, 90210" star Denise Dowse slipped into a coma after contracting a "virulent form" of meningitis.

Her sister, Tracey Dowse, posted a statement on the actress' Instagram page Sunday, requesting support and prayers from everyone. She further said the doctors were unable to confirm when the actress will wake up from the coma.

"Hello family and friends, as many of you have seen, my posts have been positive and uplifting. I am trying to keep my spirits up and support those who need it. As many of you know I am a private person. So this is hard for me," Tracey wrote in the post.

"I am requesting support and prayers be offered me and my sister, and my only immediate family Denise Dowse. She is currently in the hospital in a coma brought on by a virulent form of meningitis. Her doctors do not know when she will come out of the coma as it was not medically induced," she added.

Tracey described her sister as "a vibrant actor and director that should have many years ahead of her."
