Growth in Children at Risk for Celiac Disease & Emapalumab for Hemophagocytic Lymphohistiocytosis

Briefly noted:  R Auricchio et al. Archives of Disease in Childhood 2020; http://dx.doi.org/10.1136/archdischild-2019-317976. Growth rate of coeliac children is compromised before the onset of the disease Thanks to Mike Hart for the reference.

Methods:   We analysed the growth patterns of infants at genetic risk of CD, comparing those who developed CD by 6 years of age (CD ‘cases’, 113 infants) versus those who did not develop CD by 6 years (no CD ‘controls’, 831 infants).

Key finding: The growth of children at risk of CD rarely fell below ‘clinical standards’. However, growth rate was significantly lower in cases than in controls. Our data suggest that peculiar pathways of growth are present in children who develop CD, long before any clinical or serological signs of the disease appear.

F Locatell et al. NEJM 2020; 382: 1811-22. This open-label study (n=34) investigated emapalumab, a human anti-interferon-gamma antibody, for the treatment of primary hemophagocytic lymphohistiocytosis (HLH). Of the 26 patients who completed the study, approximately 65% had a response (based on clinical and lab features) and were able to proceed to transplantation.
