Abstract

Acute splenic sequestration (ASS) and chronic hypersplenism are common features of homozygous sickle cell (SS) disease in the first 5 years of life affecting one-third of subjects in the Jamaican Cohort Study. The risk factors are largely unknown and the current study explores a possible role of genetic factors. We have explored these in subjects who received splenectomy in the management of ASS (n=8) or chronic hypersplenism (n=9) along with age, gender, and genotype matched controls using Luminex Technology to assess 42 human cytokines/chemokines, including IL-1α and CXCL10 (IP-10). Levels of IL-1α (p=0.008) and CXCL10 (p=0.009) were significantly elevated in patients treated by splenectomy compared with the control group. Levels of IL-1α were significantly higher in those with a history of ASS compared with matched normal controls (p=0.028) but not in those treated for hypersplenism (p=0.093). Furthermore, several significant differences were found in the median ratios of some cytokine biomarkers between the splenectomized group and the normal controls. These observations are consistent with acute splenic sequestration having a distinct phenotype which may be helpful in predicting those at risk of this complication and suggest that the mechanism of these differences merit further study.
