The story on HLH

Truro Daily News - - COLCHESTER COUNTY -

HLH can be in­her­ited or ac­quired. When it oc­curs in chil­dren, it is usu­ally be­cause both par­ents are ge­netic car­ri­ers.

In adults, it can be caused by con­di­tions such as in­fec­tions and can­cer.

It causes cer­tain white blood cells – his­ti­o­cytes and lym­pho­cytes – to at­tack other blood cells. The ab­nor­mal blood cells also col­lect in

the spleen and liver and cause the or­gans to en­large. Symp­toms can in­clude per­sis­tent fever, rash, en­larged lymph nodes, ane­mia, jaun­dice, res­pi­ra­tory is­sues, seizures, and low white blood cells.
