Host Factors • Findings of familial clustering of cases & concordance in monozygotic twins— particularly for chorea—confirm that susceptibility to ARF is an inherited characteristic. • HLA class II alleles • ↑levels of circulating MBL & polymorphisms of TGF-β1 gene and immunoglobulin genes Immune Response Immune Response • Epitopes present in the cell wall, cell membrane, and the A, B, and C repeat regions of the streptococcal M protein are immunologically similar to molecules in human myosin, tropomyosin, keratin, actin, laminin, vimentin, and N-acetylglucosamine. • Human molecules—particularly epitopes in cardiac myosin—result in T cell sensitization. Immune Response • Laminin, another -helical coiled-coil protein like myosin and M protein, which is found in cardiac endothelium and is recognized by antimyosin, anti-M protein T cells. • Antibodies to cardiac valve tissue cross-react with the N-acetylglucosamine of group A streptococcal carbohydrate, and there is some evidence that these antibodies may be responsible for valvular damage.

Harrison’s Principles of Internal Medicine, 17th ed. REVISED JONES CRITERIA 2002-2003 WHO Criteria for the Diagnosis of RF and RHD “Probable Rheumatic Fever” – with polyarthritis (or with only polyarthralgia or monoarthritis) and with several (3 or more) other minor manifestations, plus evidence of recent group A streptococcal infection. – may later turn out to be rheumatic fever – advise regular secondary prophylaxis, follow up closely and do regular heart examination (esp. in vulnerable age groups in high incidence settings) Harrison’s Principles of Internal Medicine, 17th ed. The Duke Criteria The Duke Criteria • The diagnosis of infective endocarditis is certain only when vegetations obtained are examined histologically and microbiologically. • Duke criteria is based on clinical, laboratory and echocardiographic findings. • 2 major criteria, 1 major + 2 minor criteria, or 5 minor criteria allows a definitive diagnosis. The Duke Criteria • The diagnosis of infective endocarditis is rejected if: – Alternative diagnosis is established – Symptoms resolve and do not recur within 4 days or less of antibiotic therapy – Surgery or autopsy after 4 days or less of antimicrobial therapy yields no histologic evidence of endocarditis The Duke Criteria • Illnesses not classified as definite endocarditis or rejected are considered possible cases when either 1 major + 1 minor citeria or 3 minor criteria are identified. • To fulfill a major criterion, the isolation of an organism that causes both endocarditis and bacteremia in the absence of endocarditis must take place repeatedly and in the absence of primary focus of infection. The Duke Criteria • Organisms that rarely cause endocarditis but commonly contaminate blood cultures must be isolated repeatedly if their isolation is to serve as a major criterion. The Duke Criteria • Major Criteria – Positive Blood Culture • Typical microorganisms from two separate blood cultures* • Persistently positive blood culture, defined as recovery of a microorganism consistent w/ infective endocarditis from: – Blood cultures drawn >12 hrs apart – All of three, majority of four or more separate blood cultures, with first and last drawn at least 1 hr apart – Single positive blood culture from Coxiella burnetti or phase I IgG titer > 1:800 The Duke Criteria – Evidence of Endocardial Involvement • Positive Echocardiogram – Oscillating intracardiac mass on valve or supporting structures or in the path of regurgitant jets or in implanted material, in the absence of an alternative anatomic explanation – Abscess – New partial dehiscence of prosthetic valve • New valvular regurgitation* The Duke Criteria • Minor Criteria – Predisposition* – Fever >/= 38°C* – Vascular phenomena* – Immunologic phenomena* – Microbiologic Evidence* Differential Diagnosis for the cause of dyspnea Algorithm for Dyspnea Pathophysiology DYSPNEA RESPIRATORY CARDIOVASCULAR Gas Exchanger Pump Controller Low output Normal output High output Pulmonary embolism Pneumonia Interstitial lung disease COPD Asthma Kyphoscoliosis Pregnancy Metabolic acidosis Congestive heart failure Myocardial ischemia Constrictive pericarditis Deconditioning Obesity Diastolic dysfunction Anemia Hyperthyroidism Arteriovenous shunt PNEUMONIA • infection of the pulmonary parenchyma • results from the proliferation of microbial pathogens at the alveolar level and the host's response to those pathogens • the most common way by which microorganisms gain access to the lower respiratory tract is by aspiration from the oropharynx ETIOLOGY Hospitalized patients Outpatients Non-ICU ICU Streptococcus pneumoniae S. pneumoniae S. pneumoniae Mycoplasma pneumoniae M. pneumoniae Staphylococcus aureus Chlamydophila pneumoniae Legionella spp. C. pneumoniae H. influenzae Gram-negative bacilli Respiratory viruses Legionella spp. H. influenzae Haemophilus influenzae Respiratory virusesa CLINICAL MANIFESTATIONS • • • • • • • Febrile Tachycardia Chills and/or sweats Cough that is either nonproductive or productive of mucoid, purulent, or bloodtinged sputum Pleuritic chest pain Nausea, vomiting, and/or diarrhea Fatigue, headache, myalgias, and arthralgias On physical examination: • increased respiratory rate and use of accessory muscles of respiration • increased or decreased tactile fremitus • on percussion note can vary from dull to flat, reflecting underlying consolidated lung and pleural fluid, respectively • on auscultation, crackles, bronchial breath sounds, and possibly a pleural friction rub may be heard on auscultation CONGESTIVE HEART FAILURE • Heart failure (HF) is a clinical syndrome that occurs in patients who, because of an inherited or acquired abnormality of cardiac structure and/or function, develop a constellation of clinical symptoms (dyspnea and fatigue) and signs (edema and rales) that lead to frequent hospitalizations, a poor quality of life, and a shortened life expectancy ETIOLOGY • any condition that leads to an alteration in LV structure or function can predispose a patient to developing HF. – – – – – – – – Coronary artery disease Hypertension Faulty heart valves Cardiomyopathy Myocarditis Congenital heart defects Arrhythmias Chronic diseases : diabetes, severe anemia, hyperthyroidism, hypothyroidism, emphysema, lupus, hemochromatosis and amyloidosis CLINICAL MANIFESTATIONS Type of Heart Failure Chronic heart failure (A long-term condition with signs and symptoms that persist.) Signs and symptoms • Fatigue and weakness • Rapid or irregular heartbeat • Shortness of breath (dyspnea) when you exert yourself or when you lie down • Reduced ability to exercise • Persistent cough or wheezing with white or pink blood-tinged phlegm • Swelling (edema) in your legs, ankles and feet • Swelling of your abdomen (ascites) • Sudden weight gain from fluid retention • Lack of appetite and nausea • Difficulty concentrating or decreased alertness CLINICAL MANIFESTATIONS Type of Heart Failure Acute heart failure (An emergency situation that occurs when something suddenly affects your heart's ability to function.) Signs and symptoms • Signs and symptoms similar to those of chronic heart failure but more severe, and start or worsen suddenly • Sudden fluid buildup • Rapid or irregular heartbeat with palpitations that may cause the heart to stop beating • Sudden, severe shortness of breath and coughing up pink, foamy mucus • Chest pain if caused by a heart attack Enumerate the precipitating factors of heart failure. HEART FAILURE • Pathophysiologic state wherein the heart loses its ability to pump sufficient amount of blood due to a structural or functional cardiac abnormality HEART FAILURE • A majority of the patients’ symptoms of heart failure are due to impairment of left ventricular function. • Hence, a condition that leads to an alteration in LV structure or function can predispose a patient to developing heart failure. HEART FAILURE LV dysfunction begins with some injury to the myocardium, and is a progressive process, even in the absence of a new identifiable insult to the myocardium. Cardiac remodelling occurs in association w/ homeostatic attempts to decrease wall stress through increases in wall thickness. This would then result in a change in the geometry of the LV, hence, the chamber dilates, hypertrophies and becomes more spherical HEART FAILURE HEART FAILURE PRECIPITATING CAUSES OF HEART FAILURE: Reduction in therapy Hypertension High salt intake Cardiac infection and inflammation Arrhythmias High output states Systemic infection Physical, environmental and emotional stress Pulmonary embolism Development of an unrelated illness Development of a second form of cardiac disease Differentiate low and high output failure, R/L sided heart failure, systolic and diastolic dysfunction Systolic Versus Diastolic Failure Forms of Heart Failure Sytolic Failure • Inability of the ventricle to contract normally and expel sufficient blood • Inadequate cardiac output with weakness, fatigue, reduced exercise tolerance (hypoperfusion) Diastolic Failure • Inability to relax or fill normally (elevation of filling pressures) • Due to increased resistance to ventricular diastolic capacity, impaired ventricular relaxation, and myocardial fibrosis and infiltration Management 10. How do you manage this patient on the following conditions? RF? Tight MS? Congestive Heart Failure • Patients With Reduced Left Ventricular Ejection Fraction – If with fluid retention: • Use diuretics (thiazides) – Medications that should be AVOIDED: • Anti-arrhythmics • Calcium channel blockers • NSAIDs Circulation; Journal of the AHA http://circ.ahajournals.org/cgi/content/full/119/14/1977 Congestive Heart Failure • Patients With Reduced Left Ventricular Ejection Fraction – Recommendations concerning aldosterone antagonists: • carefully selected patients with moderately severe or severe HF symptoms and recent decompensation or with LV dysfunction early after MI Circulation; Journal of the AHA http://circ.ahajournals.org/cgi/content/full/119/14/1977 Congestive Heart Failure • Patients With Refractory End-Stage Heart Failure (Stage D) – Intravenous Peripheral Vasodilators and Positive Inotropic Agents: • hospitalized frequently for clinical deterioration, and during such admissions, they commonly receive infusions of both positive inotropic agents (dobutamine, dopamine, or milrinone) and vasodilator drugs (nitroglycerin, nitroprusside, or nesiritide) Circulation; Journal of the AHA http://circ.ahajournals.org/cgi/content/full/119/14/1977 Congestive Heart Failure The Hospitalized Patient Common Factors That Precipitate Hospitalization for Heart Failure • Noncompliance with medical regimen, sodium and/or fluid restriction • Acute myocardial ischemia • Uncorrected high blood pressure • Atrial fibrillation and other arrhythmias Circulation; Journal of the AHA http://circ.ahajournals.org/cgi/content/full/119/14/1977 Congestive Heart Failure The Hospitalized Patient Common Factors That Precipitate Hospitalization for Heart Failure • Recent addition of negative inotropic drugs (e.g., verapamil, nifedipine, diltiazem, beta blockers) • Pulmonary embolus • Nonsteroidal anti-inflammatory drugs Circulation; Journal of the AHA http://circ.ahajournals.org/cgi/content/full/119/14/1977 Congestive Heart Failure The Hospitalized Patient Common Factors That Precipitate Hospitalization for Heart Failure • Excessive alcohol or illicit drug use • Endocrine abnormalities (e.g., diabetes mellitus, hyperthyroidism, hypothyroidism) • Concurrent infections (e.g., pneumonia, viral illnesses) Circulation; Journal of the AHA http://circ.ahajournals.org/cgi/content/full/119/14/1977 Rheumatic Fever • Inflammatory disease that may develop two to three weeks after a Group A streptococcal infection (such as strep throat or scarlet fever). • Caused by antibody cross-reactivity and can involve the heart, joints, skin, and brain Rheumatic Fever The management of acute rheumatic fever is geared toward the reduction of inflammation with anti-inflammatory medications such as aspirin or corticosteroids. 1.Antibiotics 2.Anti- inflammatory Drug Antibiotics Erythromycin Penicillin V • Antibiotics that is used to treat infections such as respiratory tract and soft tissue infections. • Antimicrobial spectrum of macrolides is slightly wider than that of penicillin, macrolides are a common substitute for patients with a penicillin allergy. • Beta-hemolytic streptococci is usually susceptible to macrolides • Phenoxymethylpenicillin is the orally active form of penicillin. • Phenoxymethylpenicillin exerts a bactericidal action against penicillinsensitive microorganisms during the stage of active multiplication. • Used only for the treatment of mild to moderate infections, and not for chronic, severe, or deepseated infections since absorption can be unpredictable • Used as primary and secondary prophylaxis for RF Anti- inflammatory Drugs • Corticosteroids and salicylates cannot prevent or modify the development of subsequent rheumatic heart disease but are used for symptomatic relief • Avoid anti-inflammatory drugs until diagnosis is confirmed, as they may mask symptoms essential to the diagnosis Anti- inflammatory Drugs NSAIDS • Act as non-selective inhibitors of the enzyme cyclooxygenase, inhibiting both the cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) isoenzymes. • lowering an elevated body temperature and relieving pain without impairing consciousness) and, in higher doses, with antiinflammatory effects. Aspirin • Acetylsalicylic Acid • Acetyl derivative of salicylic acid that is a white, crystalline, weakly acidic substance, with melting point 137°C. • It is useful in the relief of headache and muscle and joint aches. • Aspirin is also effective in reducing fever, inflammation, and swelling and thus has been used for treatment of rheumatoid arthritis, rheumatic fever, and mild infection. Aspirin Common Side Effects • Heartburn; nausea; upset stomach. Severe Side Effects • Severe allergic reactions (rash; hives; itching; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue); black or bloody stools; confusion; diarrhea; dizziness; drowsiness; hearing loss; ringing in the ears; severe or persistent stomach pain; unusual bruising; vomiting. Anti- inflammatory Drugs Corticosteroid • Drugs that are closely related to cortisol, a hormone which is naturally produced in the adrenal cortex. • Act on the immune system by blocking the production of substances that trigger allergic and inflammatory actions, such as prostaglandins. • They also impede the function of white blood cells which destroy foreign bodies and help keep the immune system functioning properly. • Interference with white blood cell function yields a side effect of increased susceptibility to infection. Anti- inflammatory Drugs Corticosteroids • Used in severe carditis and CHF and also prevents the complications of carditis. • High-dose prednisone is administered for 2-3 wk, then tapered over 3 wk. IV corticosteroids are reserved for fulminant cases. • Rebound occurs frequently with corticosteroids; hence, they require gradual tapering rather than abrupt cessation. Prednisone • Synthetic corticosteroid drug that is particularly effective as an immunosuppressant, and affects virtually all of the immune system. • Used in severe carditis and CHF. • High-dose prednisone is administered for 2-3 wk, then tapered over 3 wk. IV corticosteroids are reserved for fulminant cases. Prednisone Minor Side Effects • stretchmarks;nervousness; acne ; rash; increased appetite; hyperactivity; frequent urination; diarrhea; removes intestinal flora; leg pain; sensitive teeth Major Side Effects • Micrograph of fatty liver, as may be seen due to long-term prednisone use.; weight gain; facial swelling; depression, mania, psychosis or other psychiatric symptoms; unusual fatigue or weakness; mental confusion / indecisiveness; blurred vision; abdominal pain; peptic ulcer; infections; painful hips or shoulders; Steroid-induced osteoporosis; Long term migraines; insomnia; severe joint pain; cataracts; anxiety; black stool; stomach pain or bloating; severe swelling; mouth sores or dry mouth; avascular necrosis; hepatic steatosis Mitral Stenosis • Mitral stenosis is a condition in which the mitral valve leaflets become thickened and the commissures fused along with thickening and shortening of the chordae tendineae. • Approximately 40% of all patients with rheumatic heart disease. • Goal of medical therapy is to control the rapid ventricular rate. Medical Therapy • Symptom Control – Beta blockers & Nondihydropyridine CCB • To slow the ventricular rate of patients w/ AF – Digoxin (rate control of AF) – Cardioversion for new onset AF and HF • Undertaken after patient has had at least 3 consecutive wks of anticoagulant tx – Diuretics for HF Medical Therapy • Warfarin – INR of 2-3 – given indefinitely to patients w/ MS who have AF or a hx of thromboembolism • Penicillin prophylaxis of Grp A β-hemolytic streptococcal infection – Prevent RF Mitral Valvotomy Indication: Symptomatic (NYHA Functional Class II-IV) patients w/ isolated MS whose effective orifice (valve area) is <~1.0cm2/m2 body surface area, or 1.5 cm2 in normal-sized adults Percutaneous mitral balloon valvotomy Surgical valvotomy
