Abstract Gaucher disease ”GD” is one of the most common glycolipid storage disorders, caused by a genetic deficiency of lysosomal β- glucocerebrosidase, encoded by GBA gene, leading to accumulation of the substrate glucocerebroside in the cells of the macrophage monocyte system. Glucocerebroside engorged cells, termed Gaucher cells, infiltrate various organs, leading to multisystem organomegaly, pancytopenia and bone complication (Hassan, 2017). A number of biochemical abnormalities have been described in GD, and it is therefore not surprising that several markers have been developed in an attempt to evaluate response to treatment (Vellodi et al., 2005). In this study, our aim of work is to analyze iron profile, hepcidin and selected inflammatory parameters, including serum cytokine (CCL18) in Gaucher patients in comparison to normal population, and Secondary was to correlate these results with patients genotype and severity scoring index. We enrolled 100 subjects for study 50 gaucher patients (confirmed by had β-glucocerebrosidase deficiency) and 50 (age- and sex- matched) normal children. Full clinical examination, investigations were done. In our study patients with confirmed GD baseline serum ferritin level showing significant hyperferritenemia (mean 184.30), with highly significant difference in ferritin levels between pre and post ERT (P-value: 0.000). We found that there is highly significant difference in serum hepcidin levels GD patients between gaucher patients (median 1350) and controls (median 400) (p-value: 0.000) with serum hepcidin 4 times higher than normal controls. Serum CCL18 levels were significantly higher in gaucher patients than controls (p-value 0.000). Median plasma CCL18 level in patients was 55 ng/mL, whereas the median level in controls samples is 5 ng /mL. We have confirmed that CCL18 is greatly elevated in the serum of patients with GD. We found that there was positive correlation between CCL18 and SSI (published by Zimran and co-workers) and splenic volume. The longitudinal improvement seen in multiple laboratory parameters documents the amelioration of the chronic effects of storage and, taken together, is evidence that ERT reverses the progressive nature of GD. These findings are consistent with the numerous reports of clinical relapse in patients who experience treatment interruptions, and they emphasize the importance of early initiation of and continuous treatment with ERT for symptomatic patients |
