Reality star Kim Kardashian West on Tuesday put her considerable social media influence behind a drive to find a bone marrow donor match for a Jewish father of three in Los Angeles who has been diagnosed with a rare form of blood cancer.

Israeli Adam Krief, 31, who lives in California, was diagnosed two months ago with primary myelofibrosis, and searches for a suitable donor have so far been unsuccessful.

In messages posted to her Facebook and Twitter accounts, Kardashian called on the public to be tested in the hope of finding a match for Krief, who has a rare blood type.

Some 29,288,000 people have ‘liked’ Kardashian’s main Facebook page, and the internationally known star has over 48 million followers on Twitter.

A donor match drive is scheduled for Israel on Wednesday, with testing available at dozens of locations across the country. Initial screening for a blood type involves a simple saliva swab.

The testing also hopes to find a match for two-year-old Adam Goman, of the central Israeli city of Modi’in, who was diagnosed with myelodysplasia and also needs a bone marrow transplant.

Hadassah University Medical Center in Jerusalem Ein Kerem and the Ma’avak Lehayim (Struggle for Life) organization are hoping to raise NIS 4 million ($1,066,000) to help pay for the saliva tests, which cost NIS 200 ($53) to process.

The Hope 4 Adam Facebook page details the efforts to find a match for Krief.
