BACKGROUND: The antiallergic and antiasthmatic drug disodium cromoglycate (DSCG) has also demonstrated an activity against sickle cell disease, but the mechanism of this action still remains unknown. METHODS: Na(+) and K(+) fluxes were studied in red cells obtained from 9 patients affected with sickle cell disease in the absence or in the presence of 1 mM of DSCG and deoxygenated under an N(2) flow during up to 24 h. RESULTS: A significant inhibiting effect of DSCG on the intracellular K(+) exit and the Na(+) entry was observed. CONCLUSION: These results demonstrate that DSCG partially inhibits the abnormal K(+) loss which is implicated in the dehydration of the sickle cell and the stimulation of sickling.
