the aim of this study is to: evaluate the association between serum ferritin levels and the clinical presentation and short-term prognosis of patients with DKA. Specifically, the correlation between its level and the severity of DKA at presentation and determine its prognostic value in predicting short-term outcomes.

Ferritin studies and correlation to acute events like stroke or Mi was done before, however some studies have found a correlation with the degree and prognosis of these diseases and others not. However no study was tried on DKA patients before so the investigators are trying to find if Ferritin would have a relation with patients of Dka and could be used as a prognostic tool (for example we found in this study when level is less than "200" patients mostly has good prognosis) this is just an example or (serrum ferritin turned out to be irrelevant to DKA prognosis as patients would have good prognosis despite number value) and this will be in selected patients according to criteria to exclude any chronic condition in the investigators hospital care units.
