M C Anyasodor, A Bewley
We describe a case of an HIV-negative man who was mistakenly diagnosed as having systemic sarcoidosis, which led to a delay in diagnosing tertiary syphilis and Kaposi sarcoma (KS). The patient presented initially with scrotal swelling and leg oedema. Initial blood tests were unremarkable and HIV testing was negative. The patient then developed unilateral limb weakness. Computed tomography showed lung lesions and hilar lymphadenopathy, while magnetic resonance imaging showed an increased signal in the cervical cord...

OBJECTIVE: To investigate whether serum angiotensing-converting enzyme (ACE) and uterine artery Doppler (UAD) are useful markers as predictors of preeclampsia (PE) in a high-risk population. METHODS: Patients at risk of PE (n = 68) were subclassified as having PE (n = 8) or no PE (n = 60). Blood samples were obtained between 19 and 22 weeks of gestation. Doppler ultrasound of the uterine arteries was done at the time of blood sampling. Maternal serum ACE was determined through spectrophotometry assay (A15 Biosystem, ATOM, Barcelona, Spain)...

BACKGROUND: A recent study suggested that addition of a direct renin inhibitor to either an angiotension-converting enzyme (ACE) inhibitor (ACEi) or an angiotensin receptor blocker (ARB) may increase stroke risk in people with diabetes and renal disease. METHODS: We examined the effects of addition of an ACE inhibitor (ramipril) to an ARB (telmisartan) for a mean follow-up of 56 months in people with diabetes [n = 9628, mean age 66 years, baseline blood pressure 144/82 mmHg, BMI 29 kg/m², estimated glomerular filtration rate (eGFR) 73 ml/min, and urine albumin 11 mg/mmol] who participated in the ONTARGET trial, divided by those with (n = 3163) and without (n = 6465) nephropathy...

We have developed murine models of viral myocarditis induced by encephalomyocarditis (EMC) virus in which severe myocarditis, congestive heart failure and dilated cardiomyopathy occur in high incidence. From these models, we have learned the natural history and pathogenesis and assessed not only new diagnostic methods but also therapeutic and preventive interventions. Autoantibodies against cardiac troponin I appeared in spontaneously developing autoimmune myocarditis in PD-1 deficient mice, who lack the T-cell receptor costimulatory molecule PD-1...

Neurosarcoidosis, rare in patients with sarcoidosis, may present with protean manifestations according to the regions of involvement from peripheral nerves to the central nervous system. Cavernous sinus is rarely involved by sarcoidosis, and it can result in different cavernous sinus syndromes based mainly on the involvement of the trigeminal nerve. We report a 54-year-old man with pulmonary sarcoidosis and cavernous sinus syndrome and review the clinical course, laboratory findings, and neuroradiologic features of the condition...

OBJECTIVE: Sherpas are well-known for their physical strength at high altitudes. They adapt to high altitude so well that little acute or chronic mountain sickness has been documented in them. The possible genetic basis for this adaptation is, however, unclear. The objective of this study was to elucidate the genetic background underlying this characteristic among Sherpas with respect to the angiotension-converting enzyme (ACE) gene. METHODS: We enrolled 105 Sherpa volunteers in Namche Bazaar (3440 meters) and 111 non-Sherpa Nepalese volunteers in Kathmandu Valley (1330 meters) in Nepal...

REVIEW
Khalid Rahman, Gordon M Lowe
Epidemiologic studies show an inverse correlation between garlic consumption and progression of cardiovascular disease. Cardiovascular disease is associated with multiple factors such as raised serum total cholesterol, raised LDL and an increase in LDL oxidation, increased platelet aggregation, hypertension, and smoking. Numerous in vitro studies have confirmed the ability of garlic to reduce these parameters. Thus, garlic has been shown to inhibit enzymes involved in lipid synthesis, decrease platelet aggregation, prevent lipid peroxidation of oxidized erythrocytes and LDL, increase antioxidant status, and inhibit angiotension-converting enzyme...

Vascular lesions are an increasing challenge after renal transplantation due to the wider indications for recipients and acceptance criteria for donors. Diagnostic approach and prognostic interpretation are still matter of controversy. The case reported herein may summarize some of the issues in this regard. A 54-year-old woman, on renal replacement therapy since 1974, and a kidney graft recipient from 1975 to 1999, received a second graft in 2001. The donor age was 65 years (cold ischemia 22 hours; two mismatches)...

Acute myocardial infarction (AMI) is a highly dynamic event, which is associated with marked neuroendocrinological dysfunction in addition to cardiac damage. The immediate trigger for AMI is not precisely known. Studies conducted by Lown, Braunwald, Halberg, Otsuka and our group have demonstrated a marked increase in sympathetic activity, oxidative stress, and magnesium and potassium deficiency during AMI. Clinical studies have reported an increased incidence of AMI, sudden death and ischemia during first quarter of the day when there is a rapid withdrawal of vagal activity and increase in sympathetic tone...

Angiontension-converting enzyme inhibitors (ACEIs) are beneficial in the treatment of diabetic and nondiabetic kidney disease, coronary artery disease and congestive heart failure. One adverse effect of ACEIs use is a rise in serum creatinine and potential renal failure. This paper attempts to quantify this risk and assess the need for pre- and post-ACEI serum creatinine measurements. A computerized search of Kaiser Permanente Northwest's electronic medical record was conducted to find patients over the age of 40 years taking lisinopril between July 1, 2000 and June 30, 2002...

Despite incessant tachycardia, not all patients develop tachycardia-mediated cardiomyopathy. The cardiac renin-angiotensin system may be involved in cardiac remodelling and fibrosis. The level of angiotension-converting enzyme (ACE) in the serum is associated with a 287 bp insertion (I)/deletion (D) polymorphism in intron 16 of the ACE gene. The DD genotype is associated with increased serum ACE levels and a higher incidence of idiopathic dilated and ischemic cardiomyopathy. The objective of this study was to assess whether the ACE gene I/D polymorphism is responsible for development of tachycardia-mediated cardiomyopathy...

The renin-angiotension-aldosterone system (RAAS) was studied in 93 patients with pulmonary tuberculosis complicated by chronic heart failure (CHF). Radioimmunoassay was used to determine plasma renin activity (PRA) and serum angiotensin I and aldesterone levels. There was higher RAAS activity, as shown by elevated PRA. RAAS activity decreased during CHF treatment with angiotension-converting enzyme inhibitors (captopril, ramipril, prestarium) and an angiotensin II-receptor blocker (cosaar), which is indicative of the efficiency of CHF treatment...

A method is described for determination of serum angiotension-converting enzyme by capillary electrophoresis (CE) based on incubation of the substrate, a synthetic peptide, with the serum outside the capillary and cleaving hippuric acid and a dipeptide. The reaction is stopped by the addition of acetonitrile, followed by injection of the supernatant on the capillary. The acetonitrile allows injection of a large volume of sample on the capillary. Both the substrate and the reaction product (hippuric acid) can be monitored at the same time...

Serum levels of angiotension converting enzyme (ACE) are elevated in many patients who suffer from sarcoidosis. Few studies have correlated ACE levels at diagnosis with the radiographic stage of the disease. The present authors reviewed the charts of all patients who had the diagnosis of sarcoidosis made between 1990 and 1995, and correlated ACE level at diagnosis with radiographic stage. Only patients with biopsy-proven sarcoid were included. One hundred and sixteen cases were identified, and complete data were available for 104 individuals...

Chronic consumption of the highly specific angiotension-converting enzyme inhibitor captopril was found to decrease the activity of the enzyme in the rat hypothalamus and striatum and to enhance it in the pituitary and blood serum. The agent also increased the activity of carboxypeptidase N in the serum and that of carboxypeptidase H in the pituitary. Reserpine, a catecholaminergic blocking agent, reduces the pituitary and serum activities of angiotensin-converting enzyme and activates soluble carboxypeptidase H in the pituitary and striatum and membrane-bound carboxypeptidase in the hypothalamus and striatum...
