Clinical genetic testing is available for the four genes known to cause familial hemophagocytic lymphohistiocytosis, types The intended audience for the GTR is health care providers and researchers.

Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. Treatment Treatment. The best treatment options for hemophagocytic lymphohistiocytosis HLH are determined by a number of factors, including the severity of symptoms, the age of onset, and the underlying cause of the condition.

In acquired HLH, it is often necessary to treat the underlying condition. For example, antiobiotics or antiviral medications can be used to treat or prevent infections that may have triggered the exaggerated immune response.

Allogeneic hematopoietic cell transplantation is considered a cure for familial HLH. It is often recommended that people with confirmed or suspected familial HLH undergo this treatment as early in life as possible.

FDA-approved indication: November , emapalumab Gamifant was approved for the treatment of adult and pediatric newborn and older patients with primary hemophagocytic lymphohistiocytosis HLH with refractory, recurrent, or progressive disease or intolerance of conventional HLH therapy.

The long-term outlook prognosis of familial forms without treatment is poor, with a median survival of less than 2 months to 6 months after diagnosis. Find a Specialist Find a Specialist.

Patient Registry A registry supports research by collecting of information about patients that share something in common, such as being diagnosed with Familial hemophagocytic lymphohistiocytosis. The type of data collected can vary from registry to registry and is based on the goals and purpose of that registry.

Some registries collect contact information while others collect more detailed medical information. Learn more about registries. Organizations Organizations. Organizations Providing General Support. Treatment is very important for patients with HLH because the condition is life-threatening.
