Some biological parameters favored a macrophagic activation syndrome: median lymphocyte count 900/mm3 (IQR: 650–1,368), moderately elevated transaminase levels [aspartate aminotransferase 62 IU/L (IQR: 36–105), alanine transaminase 52 IU/L (IQR: 25–89), triglycerides 2.4 mmol/L (IQR: 1.8–3.3), and lactate dehydrogenase 345 IU/L (IQR: 271–420)]. Here, GPT is linked to macrophage activation syndrome.
