Immobilized angiotensin-converting enzyme (ACE) was utilized as an affinity ligand to isolate a naturally occurring ACE binding protein from normal human serum. The enzyme was isolated from solubilized bovine lung membrane preparations by lisinopril affinity chromatography. It had an estimated molecular weight of 180 000 and was recognized by the anti-ACE antibody for the rabbit testicular ACE in immunoblots. ACE was immobilized onto epoxy Sepharose as well as Affi-Gel 15. Immobilized ACE on Affi-Gel 15 had higher catalytic activity (0.176 U/mL) compared with the enzyme immobilized on epoxy Sepharose (0.00005 U/mL). Immobilized ACE served as the affinity ligand for the identification of the ACE binding protein in human serum with an estimated molecular weight of 14 000 as observed by SDS polyacrylamide gel electrophoresis. The identification and further characterization of ACE binding proteins in serum and tissues may facilitate the greater understanding of the endogenous regulation of this key enzyme, which is involved in blood pressure homeostasis.

Lisinopril in hypertension associated with renal impairment.
Donohoe JF, Laher M, Doyle GD, Cooper WD.
The antihypertensive efficacy and safety of lisinopril, a long-acting angiotensin-converting enzyme inhibitor, were assessed in 23 patients with hypertension associated with impaired renal function (glomerular filtration rate 60 ml/min or less) in an open study of 12 weeks' duration. Lisinopril was given orally in single daily doses. The starting dose was 2.5 mg in patients with glomerular filtration rate (GFR) of less than 30 ml/min and 5 mg in all other patients. This was titrated to a maximum of 40 mg daily according to blood pressure response. A diuretic was then added if blood pressure was not controlled. Mean sitting and standing blood pressures were significantly reduced by lisinopril treatment. The median dose of lisinopril taken was 10 mg daily (range 2.5-40 mg), and only three patients required the addition of a diuretic. The mean glomerular filtration rate was unchanged during the study (38 +/- 16.4 ml/min at baseline, 41 +/- 21.0 ml/min after 12 weeks of treatment). Twenty-two patients completed the study. One patient was withdrawn because of nausea and vomiting due to reflux oesophagitis which was probably not drug related. Another patient had transient mild angioneurotic oedema and continued on lisinopril. No clinically significant haematological or biochemical changes were observed. In conclusion, lisinopril provided effective blood pressure control and was well tolerated in this group of hypertensives who are typically difficult to treat.

Lisinopril in elderly patients with hypertension.
Laher MS, Natin D, Rao SK, Jones RW, Carr P.
The antihypertensive efficacy and safety of lisinopril, a long-acting angiotensin-converting enzyme inhibitor, were assessed in 40 elderly patients (aged 65 years or over) with mild to moderate systolic/diastolic or isolated systolic hypertension, in an open study of 12 weeks' duration. Lisinopril was given orally in single daily doses. The starting dose was 5 mg in patients with glomerular filtration rate (GFR) of 30-60 ml/min and 10 mg in patients with GFR greater than 60 ml/min. The dose of lisinopril could be titrated upwards to a maximum of 40 mg daily according to blood pressure response. A thiazide diuretic was then added if blood pressure was not controlled. Thirty-six patients completed the study. Mean sitting blood pressure was significantly reduced by lisinopril treatment. There was no significant alteration in the heart rate, and postural hypotension did not occur. The median dose of lisinopril given was 20 mg daily (range 5-40 mg daily), and only two patients had a diuretic added to the lisinopril. One patient was withdrawn from the study because of unstable angina, and another was discontinued from lisinopril treatment because of anorexia and facial flushing. One patient was withdrawn after 8 weeks because of interruption of lisinopril therapy for a transurethral resection of the prostate, and one patient was lost to follow-up. No clinically significant haematological or biochemical changes were observed. The mean glomerular filtration rate was unchanged during the study. Proteinuria did not occur de novo, nor did established proteinuria increase. Thus lisinopril was well-tolerated and effective therapy in a group of elderly hypertensive patients.
