Cytokines as a Common Components of Two Different Disorders: Metabolic Syndrome and Hemophagocytic Lymphohystiositosis

Increased cytokines secretion occurs in several different disorders. Hemophagocytic lymphohystiositosis (HLH) and metabolic syndrome (MS) are consist two of them. Hemophagocytic lymphohystiositosis results from uncontrolled macrophage activation and huge amounts of cytokine secretion. The metabolic syndrome is a multicomponent condition characterized by insulin resistance, dyslipidemia, abdominal obesity, hypertension, and increased level of proinflammatory cytokines. It was presented a 6.8 years old girl, diagnosed as HLH. Because she was morbid obese, endocrinological investigation had been done and metabolic syndrome, thyroid hormone dysfunction, and hypercortisolemia with disturbances of diurnal rhythm were detected. During follow-up of patient, metabolic syndrome components disappear gradually while haemophagocytosis was recovered. Endocrine system can be affect during HLH attack, and MS can be developed. Cytokines seems to act central role of pathological changes for both diseases.
