The use of angiotensin-converting enzyme inhibitors can be accompanied by a number of adverse events, including cough, angioedema, and hyperkalemia, as well as a peculiar form of functional renal insufficiency. Other, less obvious side effects accompany ACE inhibitor use, such as a reduction in red blood cell production. This feature of ACE inhibitor use may be employed to good effect, as in the management of post-transplant erythrocytosis. Alternatively, the suppressive effect of ACE inhibitors on red blood cell production may intensify the anemia of chronic renal failure and/or congestive heart failure. The untreated congestive heart failure patient typically has an increased red blood cell mass as a consequence of increased erythropoietin levels, with the latter governed by congestive heart failure-related renal hypoxia. This is not expressed as an increase in hemoglobin concentration because of the increase in plasma volume that marks advanced congestive heart failure. ACE inhibitor therapy can be expected to both reduce plasma volume and decrease red blood cell production. As a result, the hemoglobin concentration changes very little in the ACE inhibitor-treated congestive heart failure patient and usually falls in the low normal range. Recently, erythropoietin has been employed to good effect in congestive heart failure patients with borderline anemia. (c)2000 by CHF, Inc.

Hypereosinophilic syndromes are defined by the presence of peripheral and bone marrow eosinophilia and by the infiltration of multiple organs by mature eosinophilic cells. Loffler's endocarditis is a condition in which mature eosinophils infiltrate and damage the endocardium and myocardium. Male adults who live in the tropics are the population predominantly affected by this condition. Typical clinical features include weight loss, fever, cough, rash, and congestive heart failure. In this article, we report the typical presentation of an unusual illness that occurred in 2 pediatric patients in different geographic locations. In addition, we believe that these are the youngest patients with Loffler's endocarditis reported.

In well designed studies in patients with mild to moderate hypertension, combinations of the sustained-release (SR) formulation of the nondihydropyridine calcium channel antagonist verapamil 120 to 240 mg/day and the ACE inhibitor trandolapril 0.5 to 8 mg/day were significantly more effective in reducing sitting systolic blood pressure (SBP) and diastolic blood pressure (DBP) from baseline than placebo. In most randomised studies, combinations of verapamil SR 120 to 240 mg/day and trandolapril 0.5 to 8 mg/day were significantly more effective in lowering sitting DBP and SBP than the corresponding monotherapies administered at the same dosage. Trandolapril/verapamil SR 2/180 mg/day provided significantly more effective 24-hour ambulatory blood pressure (BP) control than of the corresponding monotherapies. Moreover, trandolapril/verapamil SR reduced BP in patients inadequately controlled with either of the corresponding monotherapies. The antihypertensive efficacy of trandolapril/verapamil SR 2/180 mg/day was generally similar to that of other combinations of antihypertensive agents (metoprolol/hydrochlorothiazide, atenolol/chlorthalidone, lisinopril/hydrochlorothiazide, enalapril/hydrochlorothiazide) in patients with hypertension, including those with type 2 diabetes mellitus. Trandolapril/verapamil SR reduced BP in patients with hypertension and type 2 diabetes or primary renal disease, Black patients and elderly patients. Trandolapril/verapamil SR was more effective than the individual components administered as monotherapy in reducing proteinuria in patients with type 2 diabetes or primary renal disease. Trandolapril/verapamil SR had a neutral or beneficial effect on metabolic parameters (glucose, insulin, lipids) in patients with hypertension, including those with type 2 diabetes. Trandolapril/verapamil SR preserved left ventricular function in patients with heart failure. Fewer cardiac events occurred after therapy with trandolapril/verapamil SR than after trandolapril alone in post-myocardial infarction patients with congestive heart failure. The incidence of adverse events in recipients of trandolapril/verapamil SR was similar to that of the individual components, and that of other combination therapies. In placebo-controlled trials conducted in the US, headache, upper respiratory tract infections, cough, constipation, atrioventricular block (first degree) and dizziness were the most commonly reported adverse events in recipients of combinations of verapamil SR (120 to 240 mg/day) and trandolapril (0.5 to 8 mg/day). In conclusion, the fixed-dose combination of trandolapril/verapamil SR is an effective treatment for patients with hypertension, including those with type 2 diabetes. Trandolapril/verapamil SR tended to be more effective than monotherapy with either verapamil SR or trandolapril, and generally showed antihypertensive efficacy similar to that of other combination antihypertensive therapies. Current data support the use of trandolapril/verapamil SR as an alternative treatment when monotherapy with either agent is not effective. Data from large clinical trials currently being conducted will assist in fully defining the role of trandolapril/verapamil SR as a cardio- and renoprotective agent.

The causes and consequences of failed extubation in postoperative intensive care unit (ICU) patients were prospectively collected by clinical observation study in the surgical ICU Siriraj Hospital from 1st October 2000 to 31st March 2001. The failure rate was 1.7 per cent (9/477). Patients underwent the following types of surgery: abdominal surgery 66.67 per cent, orthopedic 22.22 per cent, and head-neck surgery 11.11 per cent. Reasons for reintubation were respiratory failure 55.56 per cent (5/9), inadequate cough reflex 22.22 per cent (2/9), congestive heart failure 11.11 per cent (1/9), and acute myocardial infarction 11.11 per cent (1/9). The consequences of failed extubation were worse outcomes:- the average length of stay in these patients increased from 3.67 days to 9.3 days. The mortality rate was 33.33 per cent. Tracheostomy was required in 55.56 per cent. From these observations we conclude that extubation should be performed at the appropriate time for each patient. This will differ according to the patient and his/her circumstances.

We present a two-part review of the English-language literature pertaining to drug therapy for systemic high BP in patients with pulmonary diseases. Part I examines the literature pertaining to the use of antihypertensive drugs in patients with systemic hypertension and coexisting pulmonary conditions, especially COPD and asthma. Part II of the series reviews studies assessing the relationship between sleep-disordered breathing (including the role of the sympathetic nervous system) and systemic hypertension, and presents an approach to the management of these patients. It is the aim of both parts of this review to make qualified conclusions and recommendations applying a methodologic critique to assess the current literature. In the first part of this series, we review the demographics of hypertension in patients with COPD. This is followed by an extensive review of the use of specific classes of antihypertensive drug therapies in patients with pulmonary disease. The antihypertensive agents reviewed include diuretics, calcium antagonists, angiotensin-converting enzyme inhibitors, and angiotensin II receptor antagonists, beta-adrenergic blocking agents, and alpha-beta-blockers and other non-beta-blocker classes. Additionally, the renin angiotensin system is briefly reviewed, with a discussion of how angiotensin-converting enzyme inhibitors induce cough, especially in pulmonary and congestive heart failure patients.

Angiotensin-converting enzyme (ACE) inhibitors and more recently angiotensin-receptor blockers (ARBs) have become popular therapies in the end-stage renal disease (ESRD) patient. The ability of either of these drug classes to reduce blood pressure in the ESRD patient is well accepted; however, there is considerably less information available to guide the clinician in the safe and effective use of these drugs in the ESRD patient with congestive heart failure and/or coronary artery disease. Head-to-head studies in the ESRD patient are lacking for both drug classes. Several pharmacokinetic factors can influence the selection of these drugs, including dialysability and the propensity for systemic accumulation. ACE inhibitors (ACE-Is) and ARBs are recognised as having a range of nonpressor effects that are pertinent to patients with ESRD. Such effects include their ability to decrease both thirst drive and erythropoiesis. These drug classes, though, are distinguishable by the unique adverse effect profile for ACE-Is. As is the case in patients without renal failure, ESRD patients can experience cough and, less frequently, angioneurotic oedema with ACE-Is. In the ESRD population, so-called anaphylactoid dialyser reactions can occur in conjunction with ACE-I use. The use of a drug from within the ARB class carries both less risk and permits a compound with a preferred pharmacokinetic profile limited dialysability and minimal systemic accumulation to be administered. These attributes would favour the increased use of ARBs in this population.

Our objective was to describe incidence, clinical, radiographic and microbiological features of bacteremic pneumococcal pneumonia (BPP) in our environment. A total of 101 patients (7 were treated as outpatients), older than 18 years of age suffering BPP were prospectively evaluated. The incidence was 2.8 cases per 1000 admissions, 50 were males, mean age was 59.9 years (19-97), mortality was 11.8%. Eighty three percent of fatalities occurred within 3 days of admission. Mortality rate increased with advancing age. Fever, cough and chest pain were the commonest presenting symptoms and 44% of patients had extrapulmonary manifestations. Cigarette smoking, chronic obstructive lung disease, alcoholism and congestive heart failure (CHF) were the commonest underlying conditions. CHF was more frequent in non-survivors (p = 0.002). A lobar pattern at chest radiograph predominated in survivors and a diffuse pattern in non-survivors (p = 0.007). Pleural effusion (20.7%), empyema (7.9%) and respiratory failure (7.9%) were the main complications. Underlying diseases were present in 100% of non-survivors (p = 0.03). Ninety four percent of patients were treated with beta-lactam antibiotics. Streptococcus pneumoniae was isolated from sputum in 6 cases. Three out of 101 S. pneumoniae isolates recovered from blood samples (one from each patient) presented organisms resistant to penicillin. We observed an incidence of BPP that is similar to the observed in other countries. There are clinical and radiographic differences between survivors and non-survivors. Penicillin-resistant S. pneumoniae is still an unusual problem in our area.

Hypertension remains one of the most unmet medical needs of this century. While many drugs are available for treating hypertension, efforts are still insufficient to find potent therapeutic agents since cause for hypertension in all patients is not the same. Angiotensin-converting enzyme inhibitors (ACEIs) have emerged as an important class of drugs in the treatment of hypertension, congestive heart failure (CHF), protenuric renal disease, myocardial infarction and stroke. This class of drugs blocks the conversion of angiotensin I to angiotensin II and prevents bradykinin breakdown. However, the lack of specificity of ACEIs leads to the frequent side effects like cough and angio-oedema. Recently developed, specific non-peptide and orally active angiotensin receptor blockers (ARBs) have become the prime therapeutics as they alone or co-administration with ACE inhibitors can control the renin angiotensin disorders. This review explores recent developments in the design, synthesis, and structural modifications of ACE inhibitors as well as angiotensin receptor blockers.

Obstructive sleep apnea (OSA) occurs commonly in the U.S. population and is seen in both obese as well as non-obese individuals. OSA is a disease characterized by periodic upper airway collapse during sleep, which then results in either apnea, hypopnea, or both. The disorder leads to a variety of medical complications. Neuropsychiatric complications include daytime somnolence, cognitive dysfunction, and depression. Increased incidence of motor vehicle accidents has been documented in these patients and probably reflects disordered reflex mechanisms or excessive somnolence. More importantly, vascular disorders such as hypertension, stroke, congestive cardiac failure, arrhythmias, and atherosclerosis occur frequently in these patients. The lungs may be affected by pulmonary hypertension and worsening of asthma. Recent data from several laboratories demonstrate that obstructive sleep apnea is characterized by an inflammatory response. Cytokines are elaborated during the hypoxemic episodes leading to inflammatory responses as marked clinically by elevated C-reactive protein (CRP). As elevated CRP levels are considered markers of the acute phase response and characterize progression of vascular injury in coronary artery disease, it is likely that obstructive sleep apnea could lead to worsening of vasculopathy. Moreover, as inflammatory mechanisms regulate bronchial asthma, it is also likely that cytokines and superoxide radicals generated during hypoxemic episodes could exacerbate reactive airway disease. Patients with Cough, Obstructive sleep apnea, Rhinosinusitis, and Esophageal reflux clustered together can be categorized by the acronym, "CORE", syndrome. The purpose of this manuscript is to review the inflammatory responses that occur in patients with obstructive sleep apnea and relate them to the occurrence of cardiopulmonary disease.

COPD is often accompanied with acute symptoms exacerbations. Patients in Ist stage: slide grade of COPD and IInd stage: middle grade of COPD suffer exacerbations accompanied with increased dyspnoea often together with increased cough and increased production of sputum. Patients in IIIrd stage (serious) and IVth stage (very serious) experience during exacerbations development of respiration insufficiency or its worsening and thus are usually treated in hospital. The most frequent causes of exacerbations are tracheobronchial tree infections and air pollution. The cause of approximately one third of serious exacerbations is not disclosed. Conditions which can resemble acute exacerbation are pneumonia, congestive heart failure, pneumothorax, pleural exudation, pulmonary embolism, and arrhythmia. Exacerbation treatment is symptomatic. Obstruction symptoms are treated with bronchodilatants and corticosteroids administration, hypoxemia with oxygen administration and signs of bacterial infection with antibiotics.
