As supraphysiological hydrocortisone might have additional MC activity, we integrated the individual hydrocortisone dose to obtain the MC equivalent dose (Eq-MC). Renin less than 20 mIU\/L was considered oversubstituted, renin between 20 and 60 mIU\/L as correctly substituted, and renin over 60\u2005mIU\/L as undersubstituted.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The mean dose of fludrocortisone was 82.3 \u00b1 46\u2005\u03bcg\/day. Plasma renin was abnormal in 56.7% of cases (7 patients oversubstituted and 78 patients undersubstituted). Abnormalities in electrolyte levels were observed in only 12.7% of patients. Plasma renin correlated negatively with sodium (P &amp;lt; .01) and systolic blood pressure (P = .026), and positively with potassium (P &amp;lt; .01). Doses changes in Eq-MC had a statistically significant effect on renin levels (P = .0037), with an increase of MC dose correlating with a decrease in renin level and vice versa; no correlation was observed using electrolytes or blood pressure.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Plasma renin correlates with electrolytes and blood pressure.
