Pulmonary arterial hypertension related to HIV infection: improved hemo- dynamics and survival associated with antiretroviral therapy. HIV and Respiratory Diseases MARKUS UNNEW EHR, MARTIN HOW ER, BERNHARD SCHAAF The spectrum of lung diseases in encompasses typical HIV-related complications such as TB and PCP, bacterial pneumonia, lymphomas and HIV-associated pulmonary hypertension, but also includes usual respiratory problems like acute bronchitis and asthma (see Table 1). Due to the better management of HIV+ people, comorbidities of the older patient become more important, such as COPD, bronchial carcinomas and lung fibrosis (Staitieh 2014, Feldman 2014). With ART, PCP and TB have become less frequent and pulmonary mortality has decreased (Grubb 2006, Morris 2011). HIV influences toll-like receptors and other factors of immune function that increase the risk of pneumonia (Morris 2011). Particularly in patients with respiratory pro- blems and advanced immune deficiency, it is essential to take all differential diag- noses into consideration, of which this chapter presents an outline. PCP, myco- bacterial infections and pulmonary hypertension are covered in detail in other chapters. Table 1: Pulmonary complications in HIV+ patients Infections Neoplasia Other Pneumocystis jiroveci Kaposi sarcoma (KS) Lymphocytic interstitial pneumonia (LIP) Non-Hodgkin lymphoma Non-specific interstitial pneumonia (NSIP) Bacterial pneumonia Hodgkin lymphoma Cryptogenic organizing pneumonia (COP) S. Cryptococcus neoformans Histoplasma capsulatum Toxoplasma gondii Talking with the patient The most important question: What is the immune status? The number of CD4 T cells is an excellent marker of the patient’s individual risk of opportunistic infec- tions. More important than the trough level (nadir) is the current CD4 T cell count. Above 200 cells/µl, typical opportunistic infections are unlikely. In these patients, generally “usual” problems such as acute bronchitis and bacterial pneumonia can be expected. Although the risk increases with immunodeficiency, more than half of HIV+ TB patients have more than 200 cells/µl (Wood 2000, Lange 2004). HIV and Respiratory Diseases 601 In patients with less than 200 CD4 T cells/µl the most common pulmonary disease is bacterial pneumonia, and PCP is also typical. Pulmonary Kaposi sarcoma and pulmonary Toxoplasma gondii infection tend to appear at less than 100 cells/µl but are rarely seen. Below 50 cells/µl, pulmonary infections with CMV (mostly in combination with PCP), invasive pulmonary aspergillosis (IPA), endemic fungi (Histoplasma capsulatum, Coccidioides immitis) and infections with atypical mycobac- teria occur. Especially in patients with advanced immunodeficiency, pulmonary disease might be an indicator of a systemic infection (e. Rapid invasive diagnostics are advisable in patients with low CD4 T cells. PCP patients typically have dyspnea and a non- productive cough. A large quantity of discoloured sputum is more likely to indicate a bacterial cause or a combination of infections. These patients usually see a doctor after 3-5 days of discomfort (Cilloniz 2014). Someone who has had PCP previously is at higher risk of having it again. A patient with COPD might have just an exac- erbation of his pulmonary disease. Under 200 CD4, PCP is unlikely with cotrimoxazole prophylaxis and the risk of bacterial pneumonia may be reduced (Beck 2001). When pentamidine inhalation is used for PCP prophylaxis, however, atypical PCP can present in the upper lobes. Respiratory symptoms after starting ART might result from immune reconstitution and inflammatory syndrome (IRIS). IRIS may have infectious and non-infectious causes (Grubb 2006).

When to stop ART A review of treatment interruption CHRISTIAN HOFFMANN Treatment interruptions are common. They are an important part of antiretroviral therapies whether as a clinician one approves of them or not. In the ART Collaboration Cohort (21,801 patients from 18 cohorts from Europe and North America 2002-2009), the probability of treatment interruptions was 11% after three years of ART (Abgrall 2012). Rates of interruption were markedly higher for intra- venous drug users (than men who have sex with men) and in patients younger than 30 years of age. The following chapter pro- vides an overview of the current knowledge in patients with chronic HIV infection. For treatment interruptions in patients with acute HIV infection, refer to the chapter Acute HIV infection. Viral load and CD4 T cells during treatment interruptions Almost all patients who stop treatment experience a rebound in viral load within a few weeks, even patients in whom this has been undetectable for several years. Viral load is usually detectable again within 10–20 days (Chun 1999, Davey 1999, Harrigan 1999). The viral load in compartments such as the CNS, as well as in semen and vaginal fluids, parallels that in the plasma (Garcia 1999) and is detectable in semen within only a few weeks (Ananworanich 2011).

Most antigenic and phylogenetic data were collected for reasons other than analyzing rela- tions between antigenic and phylogenetic classifications purchase valacyclovir 1000mg free shipping. Little thought has been given to the sampling schemes that maximize information about evolutionary process order valacyclovir 500 mg with mastercard. Ideal studies require analysis of the inter- actions between evolutionary process, methods of measurement, and statistical inference. ANTIGENICITY AND PHYLOGENY 187 Different sampling schemes may be needed to study different kinds of natural selection. To detect relatively slow antigenic change, one should probably sam- ple over relatively long phylogenetic distances. The average divergence of genomes over long distances sets a standard against which one can detect reduced antigenic change at sites constrained by stabilizing se- lection. By contrast, diversifying selection accelerates change by favoring anti- genic types that differ from the currently prevalent forms. To detect rel- atively rapid change, one should probably sample over relatively short phylogenetic distances. This sets a low level of background change against which rapid, diversifying change can be detected. The degree of match or discord between antigenic and phylogenetic classifications may depend on the demographic consequences of selection. If selection on a few closely linked epitopes determines the success or failure of a parasite lineage, then phylogeny may follow antigenicity. By contrast, selection may strongly influence patterns of antigenic change without absolutely determining success or failure of lineages. In this case, antigenicity does not constrain phylogeny. Mathematical models would clarify the various relations that may arise between antigenic and phylogenetic classifications. Those rela- tions depend on the time scales of differentiation, the epitopes used for antigenic classification, and the antibodies used to discriminate between variant epitopes. Experimental Evolution: Foot-and-Mouth 12 Disease Virus Experimental evolution manipulates the environment of a population and observes the resulting pattern of evolutionary change. This allows one to study the selective forces that shape antigenic diversity. For ex- ample, one could manipulate immune selection by exposing parasites to different regimes of monoclonal antibodies. The parasites’ evolutionary response reveals the adaptive potential and the constraints that shape patterns of antigenic variation. In this chapter, I describe experimental evolution studies of foot-and- mouth disease virus (FMDV). I also use this virus as a case study to show how different methods combine to provide a deeper understanding of antigenic variation. These approaches include structural analysis of the virion, functional analysis of epitopes with regard to binding cellular re- ceptors, sequence analysis of natural isolates, and experimental analysis of evolving populations. The first section introduces the antigenicity and structure of FMDV. Structural studies provide the three-dimensional location of amino ac- ids. This allows one to analyze how particular amino acid substitutions affect shape, charge, and interaction with antibodies. Structural infor- mation also aids functional analysis of substitutions with regard to bind- ing cellular receptors or affecting other components of viral fitness. The second section describes antibody escape mutants of FMDV. Most of these escape mutants were generated by application of monoclonal antibodies in controlled experimental studies. Several laboratory escape mutants occur in an exposed loop on the surface of the virion, which is also the site of a key antigenic region identified by sequencing natural isolates. This antigenic loop mediates binding to cellular receptors, an essential step for viralentryintohost cells. The pattern of antibody escape mutantsidentifiesvarying and unvarying amino acid sites. The unvarying sites play an essential role in binding to host cells. The third section continues discussion of binding to host cells and tro- pism for different host receptors.
