BACKGROUND: In HIV infection, lymphoid tissue is disrupted by fibrosis. Angiotensin converting enzyme inhibitors have anti-fibrotic properties. We completed a pilot study to assess whether the addition of lisinopril to antiretroviral therapy (ART) reverses fibrosis of gut tissue, and whether this leads to reduction of HIV RNA and DNA levels. METHODS: Thirty HIV-infected individuals on ART were randomized to lisinopril at 20mg daily or matching placebo for 24 weeks...

Angiotensin-converting enzyme inhibitor induced angioedema commonly involves the head and neck area. We report a case of angiotensin-converting enzyme inhibitor induced intestinal angioedema in a heart transplant recipient on mTOR immunosuppression. A 36-year-old Caucasian woman with history of heart transplantation on sirolimus, tacrolimus and prednisone presented to the Emergency Department with abdominal pain, one day following lisinopril initiation. A computer tomography scan demonstrated diffuse bowel wall thickening consistent with pancolitis and edema...

A new sensitive and discriminating spectrofluorimetric method has been developed and validated for determination of Lisinopril, one of the angiotensin converting enzyme inhibitors, in its pure bulk form and pharmaceutical tablets. The reaction of Lisinopril with ethylacetoacetate and formaldehyde in acidic buffered medium (pH3.8) has yielded a pale yellow product that exhibited a high fluorescence measured at 438nm after excitation at 350nm. All the experimental parameters affecting the formation and stability of the produced fluorophore were carefully investigated and optimized to give the maximum sensitivity...

Macroglossia is classified as true macroglossia, which exhibits abnormal histology with clinical findings, and relative macroglossia, in which normal histology does not correlate with pathologic enlargement. This report describes an atypical case of morbidity with massive macroglossia secondary to myxedema; the macroglossia enlarged over a 3-month period before being presented to the Department of Oral and Maxillofacial Surgery, University of Texas Health Science Center at Houston (Houston, TX). Substantial enlargement of the tongue (16 cm long × 10 cm wide) was first attributed to angioedema, which was refractory to the discontinuation of lisinopril and a C1 esterase inhibitor...

The prelimbic cortex (PL) is an important structure in the neural pathway integrating stress responses. Brain angiotensin is involved in cardiovascular control and modulation of stress responses. Blockade of angiotensin receptors has been reported to reduce stress responses. Acute restraint stress (ARS) is a stress model, which evokes sustained blood pressure increase, tachycardia, and reduction in tail temperature. We therefore hypothesized that PL locally generated angiotensin and angiotensin receptors modulate stress autonomic responses...

A 70-year-old African American man suffered anoxic encephalopathy following a choking episode. He had a history of hypertension, which was being treated with lisinopril, an angiotensin-converting enzyme inhibitor (ACEI). Soon after the patient's admission to an intensive care unit, his tongue began to swell until it reached more than twice its normal size and extended almost 2 inches outside his mouth. When the swelling did not diminish after 2 weeks, a diagnosis of ACEI-induced angioedema was determined. ACEIs have the potential to cause angioedema through an uncommon effect on the angiotensin-renin vascular control system...

Angiotensin system inhibitors (ASIs) can improve prognosis in multiple cancer types, including pancreatic ductal adenocarcinoma (PDAC). However, no study has examined the effect of ASIs alone or combined with adjuvant chemotherapy in resected PDAC patients.<br /><br />Experimental Design: We performed an analysis of the records of ASI users and non-user patients with PDAC seen at Massachusetts General Hospital between January 2006 and December 2010. To identify mechanisms of ASIs in PDAC, we performed RNA-Seq of resected primary lesions...

In experimental diabetic and nondiabetic chronic kidney disease, angiotensin-converting enzyme (ACE) inhibitor and angiotensin receptor blockers (ARB) combination therapy reduce proteinuria and prevent structural lesions more effectively than either drug alone. Consistently, in humans, a multidrug individually tailored antiproteinuric treatment based on combination therapy with maximum tolerated doses of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers ("Remission Clinic") reduced proteinuria and prevented end-stage renal disease more effectively than angiotensin-converting enzyme/angiotensin receptor blockers monotherapy, in particular in subjects with nondiabetic chronic kidney disease...

BACKGROUND: Trastuzumab (TZB) is an established therapy for HER2-positive breast cancer. The use of TZB is commonly associated with cardiotoxicity manifesting as asymptomatic decrease in left ventricular ejection fraction (LVEF) or overt heart failure. Several studies demonstrated favorable effects of angiotensin-converting enzyme (ACE) inhibitors and β-blockers (BBs) in the prevention of chemotherapy-induced cardiotoxicity. We hypothesize that patients, randomized to receive an ACE inhibitor or a BB during trastuzumab therapy for breast cancer, will maintain a higher LVEF than patients randomized to placebo...

A 57-year-old African American woman was being treated at our clinic for neurogenic urinary incontinence (UI). The UI, which occurred day and night, began 2 years earlier following a laminectomy of vertebrae C3 to C6 with spinal fusion of C3 to C7 for cervical spinal stenosis. The UI persisted despite physical therapy and trials of oxybutynin and imipramine. Since the surgery, the patient had also been experiencing chronic (debilitating) neuropathic pain in both legs, and the sensation of incomplete bladder emptying...

Randomized trials of hypertension have seldom examined heterogeneity in response to treatments over time and the implications for cardiovascular outcomes. Understanding this heterogeneity, however, is a necessary step toward personalizing antihypertensive therapy. We applied trajectory-based modeling to data on 39 763 study participants of the ALLHAT (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial) to identify distinct patterns of systolic blood pressure (SBP) response to randomized medications during the first 6 months of the trial...

Inhibitors of mTOR, including clinically available rapalogs such as rapamycin (Sirolimus) and Everolimus, are gerosuppressants, which suppress cellular senescence. Rapamycin slows aging and extends life span in a variety of species from worm to mammals. Rapalogs can prevent age-related diseases, including cancer, atherosclerosis, obesity, neurodegeneration and retinopathy and potentially rejuvenate stem cells, immunity and metabolism. Here, I further suggest how rapamycin can be combined with metformin, inhibitors of angiotensin II signaling (Losartan, Lisinopril), statins (simvastatin, atorvastatin), propranolol, aspirin and a PDE5 inhibitor...
