- Background: The storage of glucosylceramide in macrophages produces an inflammatory response in Gaucher disease type 1 (GD1) resulting in iron metabolism dysregulation and cytokine release. Patients and methods: The study included 16 adults with GD1 aged 20-86 years. All but one patient carried at least one allele with the c.1226A > G (N370S) mutation in the GBA1 gene. Ferritinemia, iron metabolism profiles including hepcidin, and inflammatory cytokine concentrations were assessed in GD1 patients in Sweden. Results: Hyperferritinemia was present in 81% of patients. There was no correlation between hyperferritinemia and patient's gender, spleen status, or clinical status. Hepcidin was discrepantly low in relation to ferritin levels. TNF-alpha was moderately increased in 5 of 11 patients; 2 patients with the highest TNF-alpha concentrations showed mildly elevated IL-6 levels. The concentrations of IL-1 beta, IL-8, and IL-10 were normal in all patients. Upon treatment, ferritinemia ameliorated but S-ferritin levels did not normalize. The increased TNF-alpha level however, normalized in all treated patients, reaching the lowest values after 2 years of therapy and continued to be stable during the remaining 2 years of follow-up. Conclusions: Hyperferritinemia is a frequent finding in GD1 in Sweden. The relatively low hepcidin levels reveal a distorted relationship between hepcidin and ferritin in GD1. Therapy has the potential to not only ameliorate hyperferritinemia but to also normalize the serum TNF-alpha concentration in GD1.
