Miliary Tuberculosis in Critical Care 24 Helmut Albrecht Division of Infectious Diseases, University of South Carolina, Columbia, South Carolina, U. While diagnostic and therapeutic issues remain, disease in most cases is not threatening enough to warrant admission to the critical care unit. The term miliary was first introduced by John Jacobus Manget in 1700, when he likened the multiple small white nodules scattered over the surface of the lungs of affected patients to millet seeds (Fig. Affected patients are typically predisposed by a weakened immune system, most notably defects in cellular immunity, resulting in the unchecked lymphohematogenous dissemination of Mycobacterium tuberculosis. Autopsy- and hospital-based case series, however, generally suffer from selection and allocation bias.

Doctors and other health care profes- sionals will need support in interpreting genomic data and their meaning for indi- vidual patients generic vasotec 10 mg online blood pressure reader. Patients will want to be able to talk about their genetic information Universal Free E-Book Store 158 5 Pharmacogenomics with their doctor order vasotec 10 mg with visa heart attack quizzes. With the right information and support, patients will be able to participate alongside their doctors in making more informed decisions. Even the most promising technologies cannot fully realize their potential if the relevant pol- icy, legal, and regulatory issues are not adequately addressed. A review of the literature indicates that pharmacogenomic research has focused mainly on non-communicable disease such as cancer, cardiovascular diseases, and neurologi- cal disorders but paid little attention to infections and orphan diseases (Olivier and Williams-Jones 2014). Analytical strategies for discovery and replication of genetic effects in pharmacogenomic studies. Now that the human genome has been sequenced, we face the greater challenge of making use of this information for improving healthcare and discovering new drugs. A detailed discussion of proteomics is given in a special report on this topic (Jain 2015). Application to development of personal- ized medicine will be discussed here briefly. Role of proteomics in drug discovery and development is termed “pharmacopro- teomics” and is a more functional representation of patient-to-patient variation than that provided by genotyping, which indicates its important role in the development of personalized medicine (Jain 2004). Pharmacoproteomics is parallel to pharma- cogenomics and is used for subtyping patients on the basis of protein analysis. Proteomics-based characterization of multifactorial diseases may help to match a particular target-based therapy to a particular biomarker in a subgroup of patients. By classifying patients as responders and non-responders, this approach may accel- erate the drug development process. Because it includes the effects of post- translational modification, pharmacoproteomics connects the genotype with the phenotype – a connection that is not always predicted by genotyping alone. Proteomics-based characterization of multifactorial diseases may help to match a particular target-based therapy to a particular marker in a subgroup of patients. Individualized therapy may be based on differential protein expression rather than a genetic polymorphism. Proteomics had a great impact on diagnosis during the first decade of the twenty- first century. By the end of the second decade protein chip-based tests will be avail- able for several diseases. Knowledge gained from genomics and proteomics will be combined to provide optimal detection of disease at an early stage for prevention or early intervention. Proteomics-based molecular diagnostics will have an important role in the diagnosis of certain conditions and proteomics-based medicines would be integrated in the total healthcare of a patient. Proteomics plays an important role in systems biology because most biological systems involve proteins. Proteins that are disturbed by disease and gene regulatory networks differ from their normal counterparts and these differences may be detected by multiparameter measurements of the blood. This will have a major role in creating a predictive, personalized, preventive, and participatory approach to medicine. Proteomic Approaches to the Study of Pathophysiology of Diseases Most of the human diseases are multifactorial and their complexity needs to be understood at the molecular level. There is no strict correlation between the gene and the actual protein expression. Therefore, the cell’s full proteome cannot be deciphered by analysis at the genetic level alone. It is necessary to look at the proteins directly to understand the disease at a molecular level. Aberrations in the interaction of proteins with one another are at the heart of the molecular basis of many diseases. For example, genomic analysis alone may not suffice in type 2 diabetes mellitus as the insulin gene may be normal and the disease may arise from an abnormality at any point in the complicated pathway that involves insulin and the complex proteins with which it interacts. Analysis of different levels of gene expres- sion in healthy and diseased tissues by proteomic approaches is as important as the detection of mutations and polymorphisms at the genomic level and may be of more value in designing a rational therapy. The proteome is dynamic and reflects the conditions, such as a disease, to which a cell is exposed. Combining the genomic with the proteomics information would, therefore, reveal a more dynamic picture of the disease process.

Role of Rapid Molecular Diagnosis at Point of Care In medicine, quantitative measurement of specific strains of infectious organisms is very important in emergency situations because the physician must start therapy immediately if the patient is in critical condition. At the same time, better testing will quickly identify the organism’s strain and drug susceptibility, reducing the delay in finding the right antibiotic. Traditional diagnostic testing often requires several days to isolate and grow the infectious organism, and to test its sensitivity to specific antibiotics. Widespread use of these antibiotics leads to the emergence of drug resistance, which then narrows the num- ber of drugs available to treat serious infections. Detection, identification, and characterization of pathogens is being revolution- ized by the combination of the seemingly disparate fields of nucleic acid analysis, bioinformatics, data storage and retrieval, nanotechnology, physics, microelectron- ics, and polymer, solid state, and combinatorial chemistry. It will be possible to miniaturize test kits, which can be swallowed or added to body fluids and coupled with data transmitters so that results can be sent to remote site for analysis. Rapid molecular diagnosis will improve the initial management of the patient, determine the need for isolation and help the selection of optimal antimicro- bials if they are needed. Nanotechnology-based tests for detection of microorgan- isms are also in development. These refinements in diagnostic technologies will not only enable personalized management of infections but will also be an important factor in the control of emergence of microbial resistance and epidemics. Natural microbiota in the gastrointestinal tract appear to contribute to nearly every aspect of physiology of the host. It may be responsible for diverse vaccine efficacy observed in humans from developing Universal Free E-Book Store 386 11 Personalized Management of Infectious Diseases Manipulation of the microbiota by probiotics and/or prebiotics is a therapeutic as well as prophylactic strategy for many infectious and inflammatory diseases within the gut, but it may be also used for improving vaccine efficacy (Długońska and Grzybowski 2011 ). Personalized Management of Sepsis Severe sepsis and septic shock are among the leading causes of death with mortality ranging between 35 % and 50 %. Adequate management of sepsis depends on early detection (earlier than conventional blood cultures) and early administration of appropriate antimicrobials. Assessment of the immune status of the host should also be done faster than that possible by conventional biomarkers. Other molecular diagnostics for sepsis are described in a special report (Jain 2015c). There is more individual variability among septic patients than previously recog- nized. Pathophysiology of sepsis is a complex and dynamic process that originates from the host immune response to infection and varies according to the genetic predisposition, immune status and co-morbid conditions of the host, the type of pathogen and the site and extent of infection. Until now, efforts to stratify septic patients according to their immune profile were hampered by the lack of specific biomarkers. Advances in molecular medicine have enabled development of tools that will facilitate a faster and more precise diagnosis of infections. Individual vari- ability between each patient’s responses to infection can assist in tailoring therapeu- tic interventions to the individual’s disease profile and monitoring treatment response. Gene profiling of the host is a promising approach because of the indi- vidualized nature of sepsis to enable personalized management (Kotsaki and Giamarellos-Bourboulis 2012). Despite the availability of adequate effective treatment, many patients default on Universal Free E-Book Store Personalized Management of Viral Infections 387 treatment, experience adverse side effects from antibiotics or fail to respond rapidly and recover. Isoniazid, one of the most important first-line tuberculosis drugs, is acetylated in the liver to a variable degree in different individuals giving rise to fast, intermediate and slow acetylator phenotypes. Acetylation status of individuals plays an important contributory role in the tuberculosis pandemic. It is important to study the acetyla- tion alleles, and to understand isoniazid metabolism and the manner in which it could affect patient compliance, isoniazid-toxicity and the emergence of drug- resistant strains of mycobacteria. The standard drug dose currently administered to patients, regardless of their acetylator status, may not be appropriate for certain people. Individualization of isoniazid therapy may help to prevent adverse drug reactions experienced by a small percentage of patients thought to be ‘slow-acetylators’ of the drug. Personalized Management of Viral Infections Antiviral therapeutics is dealt with in detail in a special report on this topic (Jain 2015a).
