Chronic exposure to these medi- cations is limited by debilitating toxicities and the development of drug resistance. Hence, there is a need to understand how the immune system can be manipulated to effect better control of viral replication and disease progression. This effort is proceed- ing in tandem with progress toward development of an effective vaccine. Immunotherapy for Infectious Diseases is intended to review the state-of-the-art developments of this rapidly emerging and evolving field. Much of the work in this area is only beginning to be appreciated by clinicians and medical scientists. We hope Immunotherapy for Infectious Diseases will not only serve as a useful guide to current knowledge of the field, but will also stimulate readers to contribute to its further devel- opment. The first sec- tion provides an overview of the basic principles of immune defense, as seen in the context of developing strategies of immunotherapy. Because many infectious agents enter and exit through mucosal surfaces, there has been growing appreciation of the role of mucosal immunity in protection against infection and immunopathogenesis. The second section discusses the principles of immunotherapy on a molecular level. The fourth section reviews immunotherapy for additional infections and virus-asso- ciated malignancies. They repre- sent some of the finest minds working in this area, and did superb jobs in reviewing the latest information in their areas of expertise. Thanks also to the secretaries and copy editors who diligently worked to put together the elements of the book. Finally, I wish to thank the readers, who I hope will use the knowledge gained from this book to advance our ability to treat infectious diseases. In 1888 Emile Roux and Alexandre Yersin isolated a soluble toxin from cultures of diphtheria. The bacterium itself is only found in the throat, but its destructive effects are found throughout the body. Clearly, the bacteria must be sending out an invisible factor, most likely chemical in nature, to cause the body-wide destruction. They filtered diphtheria cultures to remove the bacteria and then injected the remaining fluid filtrate (which we call the supernatant) into healthy animals. As expected, the animals showed diphtheria lesions but without any obvious presence of bacteria. They then took serum from animals infected with diphtheria and injected it into healthy animals. When these animals were later inoculated with diphtheria, they were found to be resistant to infection. This first demonstration of defense against infection was described as mediated by antitoxin. It was clear to von Behring and Kitasato (2) that the antitoxin was specific only for diphtheria; it did not confer any defense against other forms of infection. We now know that this antitoxin is composed of anti- bodies produced specifically against the diphtheria microbe. In 1897, Rudolf Kraus first visualized the reaction of antitoxins to bacteria by simply adding serum from infected animals to a culture of the bacteria and seeing a cloudy precipitate develop as the antibodies bound the bacteria together. Other scientists took different approaches and revealed serum-based responses toward bacteria and their products. Initially these serum properties were given a range of different names, such as precipitins, bacteriolysins, and agglutinins. Immunologic research would have to wait until 1930 before these subtly different properties were unified and recognized as a single entity. Long before antibodies were actually isolated and identified in serum, Paul Erlich had put forward his hypothesis for the formation of antibodies. The words antigen and antibody (intentionally loose umbrella terms) were first used in 1900. It was clear to Erlich and others that a specific antigen elicited production of a specific antibody that apparently did not react to other antigens. He hypoth- esized that antibodies were distinct molecular structures with specialized receptor areas. He believed that specialized cells encountered antigens and bound to them via receptors on the cell surface. This binding of antigen then triggered a response and pro- duction of antibodies to be released from the cell to attack the antigen. First, he suggested that the cells that produced antibody could make any type of antibody. He saw the cell as capable of reading the structure of the antigen bound to its surface and then making an antibody receptor to it in whatever shape was required to bind the antigen. He also suggested that the antigen-antibody interaction took place by chemical bonding rather than physically, like pieces of a jigsaw puzzle. Thus, by 1900, the medical world was aware that the body had a comprehensive defense system against infection based on the production of antibodies. They did not know what these antibodies looked like, and they knew little about their molecular interaction with antigens; however, another major step on the road had been made. We can see that the antibody system of defense was ultimately a development of the ancient Greek system of medicine that believed in imbalances in the body humors. The term humoral (from the Latin word humors) refers to the fluids that pass through the body like the blood plasma and lymph. The blood plasma is the noncellular por- tion of the blood, and the lymph is the clear fluid that drains via lymph ducts to the lymph glands and finally into the venous circulation. These fluids carry the antibodies, which mediate the humoral immune response (Fig. They are made up of a series of domains of related amino acid sequence, which possess a common secondary and tertiary structure. This conserved structure is frequently found in proteins involved in cell-cell interactions and is espe- cially important in immunology. The proteins utilizing this structure are mem- bers of the immunoglobulin supergene family.

In hypertrophic cardiomyopathy most commonly the left ventricle is the more affected chamber with the septum showing the most growth order toradol master card acute chest pain treatment guidelines. The thickening can sometimes be symmetric or concentric involving the entire left ventricular wall or localized to the apex in rare cases purchase toradol overnight delivery pain treatment center bismarck. After starting as a patchy lesion purchase genuine toradol line upstate pain treatment center, the process can gradually spread to involve the entire right ventricle and then to the left ventricle. Hypertrophic cardiomyopathy causes abnormal relaxation of the heart during diastole and secondary obstruction to venous return. In the terminal stages of this disease, the heart resembles those seen in a dilated cardiomyopathy. In restrictive cardiomyopathy there is normal systolic function but abnormal relaxation. Clinical Manifestations Cardiomyopathy is not gender, race, geography or age specific. About 50 60% of children with hypertrophic cardiomyopathy and 20 30% with dilated cardiomyo- pathy have a family history. Symptoms of hypertrophic cardiomyopathy could first manifest with the spurt of growth during puberty. Other presenting features may include a murmur, arrhythmias, chest pain and syncope. There also may be an association with a malformation syndrome with dysmorphic features specific to the syndrome, such as short stature and webbed neck seen in Noonan s syndrome. Diagnostic Testing Any suspicion of cardiomyopathy should prompt a consult to the pediatric cardiologist. Echocardiogram is the most widely used and most informative noninvasive test for diagnosing cardiomyopathy (Fig. With echocardio- gram, the practitioner cannot only specify the type of cardiomyopathy but also determine the degree of dysfunction of the heart muscle. Measurements of the pressures in the ventricles and the great vessels like the pulmonary artery may also be performed. In addition a chest X-ray, electrocardiogram and a 24 72 h Holter monitor are necessary for evaluation. In some cases there may be need for more invasive tests like radionuclide ventriculogram or cardiac catheterization. This helps in evaluating for possible infections of the heart and certain metabolic diseases. Certain biochemical, genetic and enzyme deficiency tests are needed before starting the most appropriate medical therapy. It is especially important to get a metabolic screening in children with cardiomyopathy under 4 years of age. This may require additional blood, urine and tissue testing in consultation with special- ists such as geneticists or neurologists. Improving the contractility by using dopamine and dobutamine in critically ill patients and digoxin orally as maintenance therapy. Control of symptoms related to obstruction with calcium channel blockers or beta blockers like verapamil and propranolol. Prevention of arrhythmias and sudden death with antiarrhythmics like amio- darone or disopyramide. Patients with associated metabolic disorders may need careful dietary monitoring of fats, avoidance of fasting and possible daily carnitine orally. Dual chamber pacing has been shown to decrease outflow obstruction in hypertro- phic cardiomyopathy. An automatic internal cardioverter defibrillator is recom- mended in cases of severe life threatening arrhythmias, syncope, or history of resuscitation from a cardiac arrest. Myectomy is the surgical removal of part of the thickened septal muscle that blocks the blood flow in hypertrophic cardiomyopathy. Even though it may control symptoms of heart failure secondary to obstruction, studies have not shown that this procedure prevents sudden death from arrhythmias or stops progression of the disease. Heart transplantation is the last resort when patients reach the end stage of the disease. About 20% of symptomatic infants with cardiomyopathy require a cardiac transplant within the first year of life. In addition, children greater than 50 kg are eligible for support by a device called Left Ventricular Assist System for about 3 12 months. Those with a family history of cardiomyopathy and no symptoms may continue screening every 5 years thereafter. If a specific genetic diagnosis is made all siblings should be genetically tested to assess their risk. Torchen Prognosis The overall prognosis depends on the type of cardiomyopathy and the age at first diagnosis. Up to 40% of children with a diagnosis of cardiomyopathy fail medical treatment within first year of diagnosis. Mortality and heart transplant rates are much higher in children with cardiomyopathy as compared to adults. For those children who acquire cardiomyopathy secondary to a viral infection 33% recover, 33% stabi- lize and 33% experience progression of their disease. Current 5-year survival for children diagnosed with hypertrophic cardiomyopathy is 85 95%, while it is 40 50% with dilated cardiomyopathy. Sudden cardiac deaths accounts for 50% of deaths in hypertrophic cardiomyopathy and 28% in restrictive cardiomyopathy. Case Scenarios Case 1 History: A 6-month-old girl is suspected of having reactive airway disease. For the past 2 months she has had several visits to the primary care physician for manage- ment of shortness of breath and wheezing. Inhaled bronchodilators were prescribed in the past with no significant improvement. Mother brought her because of con- cern of increasing effort to breathe and poor feeding. Physical examination: The infant appeared pale and in mild to moderate respira- tory distress with visible intercostal and subcostal retractions. Peripheral pulses were equally diminished with pro- longed capillary refill (3 s). Diagnosis: Chest X-ray showed significant cardiomegaly with prominent pulmo- nary vasculature markings suggestive of pulmonary edema. An echocardio- gram was performed which revealed dilated and poorly contracting ventricles with severe mitral regurgitation due to a dilated mitral valve ring. Laboratory studies for viral titers were obtained to investigate the possibility of viral myocarditis. Diuretics and intrave- nous milrinone were used with improved evidence of cardiac output.

In the second method discount toradol american express pain medication for dogs dose, the adjuvant solutions were prepared separately cheap toradol 10 mg pain medication for the shingles, and the pellets obtained from 10 ml of shake-ask culture of H order toradol amex pain treatment for bursitis. In both methods, at the end of the incubation period, the 20-mm-diameter mycelial mat was transferred to 10 ml of 0. Growth and conidiation of mycelial pellets on excised parts of the coconut palm The following parts of the coconut palm (Purseglove 1972) were tested for their suitability as substrates for germination and conidiation of H. These plant parts were excised into 2 small pieces (2 9 2cm for at parts, or 5 cm long for cylindrical parts) or used as such (only tepals) with each piece serving as a replicate. Observations were recorded for growth and coni- diation of mycelial pellets frequently (at least three times in a 24-h period) for up to 96 h. Effect of simulated sunlight on the conidiation of Hirsutella thompsonii Mycelial beads of H. Pellets treated with Diseases of Mites and Ticks 173 only sterile deionised water served as control. A 1100-W air-cooled xenon arc lamp gave an 2 output spectrum closely resembling sunlight in a total exposure area of 560 cm inside the simulator chamber. After sunlight treatment, the lids were replaced and two sub-sets of three Petri dishes each for the adjuvants and control were further incubated at alternating light dark regime (12:12 h) and total darkness, respectively, for 48 h at room temperature. For non-irradiated control, a similar protocol was followed with Petri dishes enclosed in black paper while inside the simulator, but other incubation conditions remained the same. At the end of the incubation period, all pellets from each Petri dish were transferred to 5 ml of sterile deionised water containing 0. Pathogenicity of adjuvant-treated pellets Before the eld trial, the three best adjuvants were tested for their effect on the patho- genicity of H. Chips (20 mm diameter) were sliced from beneath the perianth of young, freshly harvested 2 nutlets showing very high mite infestation ([20 live adult mites/mm ) after carefully removing the bracts. The pellets treated as in the plant parts study were rst allowed to germinate for 24 h and then transferred to the surface of the chip contained in the centre of a clean 200-mm glass Petri dish, at a rate of ve pellets per chip. The Petri dishes arranged in this manner were then closed and kept at room temperature with a 12-h photoperiod. The formulation process and ingredients, including the carrier and the additives (or formulants) incorporated into the nal product were the same as the original product. A block of 84 palms (7 rows 9 12 palms) at the centre of the grove was selected, out of which the rst three rows were used as a set for the fungal treatment and the last two as a set for the chemical and control treatments, with a buffer of two untreated rows in between these sub-blocks. The individual treatments were randomised 12 times each within their respective sets. After harvesting the mature coconuts from each experimental palm, the bunches were numbered by considering the fully open inorescence as the rst bunch and the preceding older bunches sequentially as second, third, etc. The second and third bunches were tagged by tying insulated electric wire of the best-visible colours, viz. For obtaining pre-treatment population data, the third nutlet from the bottom of the bunch was sampled from the fourth and fth bunches. Following the pre- treatment sampling, all the bunches were treated with the specic spray uid (2 l/palm) using a portable, lightweight, hand-compression sprayer (3. All the spray uids were prepared in plain water and applied thrice as sprays at fortnightly intervals during early mornings. The post-treatment population count of the mite was recorded in all the palms 6 weeks after the rst round of treatment. Population counts were made on two nuts, one each from both the tagged bunches, in the same way as pre-treatment analysis. Finally, during the pre- harvest stage, both the tagged bunches were cut off entirely from the palm and brought down for grading. The nuts were separated from the short peduncles from each bunch separately and were graded individually based on the damage caused by the mite. Data analysis All laboratory experiments were performed twice and the eld trial once. For the labo- ratory experiments, the results from only one trial are presented because a similar trend was observed between the trials with homogeneity of variances determined with Bartlett s test. Prior to analysis, the data from conidial counts were subjected to log(x)-transformation to improve homogeneity of variances. Data on colony counts on the lter paper and pathogenicitypwere square-root- p p transformed x. The pre-treatment x and post-treatment x 0:5 data from the eld trial were also subjected to square-root transformation. Diseases of Mites and Ticks 175 Results Effect of adjuvants on the growth characteristics of Hirsutella thompsonii The number of fungal colonies formed on the lter paper by H. Hyphal development and extension occurred in less than 24 h only in glycerol treatment. In other treatments, it took anywhere between 24 and 48 h, except in the case of gelatine and nutrient broth, both of which took longer. Several test adjuvants were able to take sporulation levels much higher than the untreated control (F9,20 = 15. Gelatine was the least effective among all the treatments with the lowest 4 numbers of conidia (2. In terms of conidia density generated on a 20-mm-diameter mycelial mat, the treatments varied signicantly. In the second method, wherein pellets were added to the adjuvant solution (F9,20 = 46. Growth and conidiation of mycelial pellets on excised parts of the coconut palm Conidiation of adjuvant-treated mycelial pellets occurred on various parts of the coconut palm but the progress of growth and conidiation was not uniform on all (Table 3). The progress of fresh fungal growth out of the pellets was the best on the nut surface or exocarp (green portion of tender nut). An unexpected shrinkage of the mycelial pellets was observed on the short peduncle as well as on the adaxial and abaxial surfaces of the leaet. Effect of simulated sunlight on the conidiation of Hirsutella thompsonii Irradiance with simulated sunlight for 1 h resulted in reduced conidiogenesis by H. Better conidiation was observed under alternating light dark regime than under total darkness in all the treatments (F3,32 = 39. The three adjuvants shielded the pellets from adverse sunlight to certain extent and helped retain enough moisture to be able to undergo conidiogenesis successfully (F3,32 = 19. Pathogenicity of adjuvant-treated pellets Prior to eld-testing of the fungus, the adjuvant-treated pellets were tested for pathoge- nicity towards the coconut mite. Glycerol-treated pellets were the most effective in terms of the mortality caused, a 16. Field trial 2 The pre-treatment counts of live mites per mm of the nut surface just below the perianth ranged from 6.
