Female HIV infection For many HIV+ women having a child now is an important part of planning for the future (Fiore 2008 10 mg zyprexa for sale, Loutfy 2009). In France 32% of the HIV+ women of reproductive age want to become mothers (Heard 2007). Treatment and care during pregnancy should be carried out according to the pre- vailing national or international guidelines (Fakoya 2008, DAIG 2011, Loutfy 2012). In some European countries reproductive options for women with unimpaired fer- tility include natural conception on the basis of the EKAF Statement as well as self- insemination, while self-insemination is still seen as the safest procedure. Couples who decide for natural conception should undergo screening to exclude STDs. The transmission risk might be further reduced when the intercourse without condoms is limited to the time of ovulation. Women should be advised on the impor- tance of adherence and regular checks of the viral load (Fakoya 2008). If a woman is not taking ART, the viral load is not successfully suppressed, or concerns about the remaining risk are strong, self-insemination may be the method of choice. In some cases, ovarian stimulation may be advisable. This, however, requires highly qualified supervision to avoid multiple gestations. A simple inexpensive way of determining whether the cycles are ovulatory, helpful in women who have regular cycles, is a basal temperature chart beginning about three months before the first self-insemination. At the time of ovulation, couples can either have protected intercourse with a sper- micide-free condom and introduce the ejaculate into the vaginal cavity afterwards, or the ejaculate can be vaginally injected using a syringe or applied with a diaphragm or portio cap. Thus the conception remains within the private sphere of the couple. After 6–12 months of unsuccessful self-insemination, the couple should have further fertility investigations with a view to assisted conception. Should the couple experience problems with self-insemination, intrauterine insemination (IUI) can be considered. HIV-specific and infective diagnostics are recommended. If no pregnancy has occurred over a period of 6–12 months (or earlier, if the couple so wishes) fertility diagnostics should be carried out (Table 1). If there are indicators of reduced fertil- ity in one or both partners, fertility diagnostics might be carried out at an earlier stage in the counselling process. Fertility disorders In some cases, women will only be able to conceive by intercourse without condom or self insemination. Dependent on the fertility status of both partners, IVF and ICSI can be considered as methods of choice. Fertility disorders in HIV+ women seem to have a higher prevalence than in an age- matched negative population (Ohl 2005, Gingelmaier 2010) and might lead to a 552 Women and Children lower success rate of assisted reproduction (Coll 2006) although data show some conflicting results. Reasons might be infection of the upper genital tract (Sobel 2000), surgery due to cervical intraepithelial neoplasia (Gilles 2005) or a depletion of mito- chondrial DNA in the oocytes (Garrabou 2006, Lopez 2008). Data reported from a program in Strasbourg indicated infertility problems in most HIV+ women. IVF and ICSI were far more effective than IUI (Ohl 2005). In the Barcelona program, Coll (2006) observed a decreased pregnancy rate after IVF com- pared to age-matched HIV-negative controls and HIV+ women who received donated oocytes. Results indicated a decreased ovarian response to hyperstimulation. A slightly impaired ovarian response to stimulation during 66 ICSI cycles in 29 HIV+ women was also described by Terriou (2005). Martinet (2006) found no difference in ovarian response between HIV+ and HIV-negative women in Brussels. Data concerning a possible association between ART and fertility disorders in women is limited (van Leeuwen 2006). Although assisted reproduction for seropositive women with fertility disorders is offered in centers in various European countries as well as the US, access to assisted reproduction often is still more limited for women than for men. HIV infection of both partners A growing number of HIV-concordant couples are now seeking reproductive coun- seling. In some centers, these couples are also accepted for reproductive treatment in case of fertility disorders. If both partners are on effective ART and there are no fertility disorders present, timed unprotected intercourse can be the method of choice. The discussion pertaining to the transmission of mutated drug-resistant virus between partners is still ongoing. Following a recent review (Redd 2013), the trans- mission rate is higher than previously assumed, showing an incidence rate of up to 7. Couples should be offered the same range of fertility counseling and screening as HIV-discordant couples. The current health of each partner should be carefully eval- uated with a full report from their HIV physician. Psychosocial aspects Experiences from more than a decade of counselling show the importance of offe- ring professional psychosocial support to couples planning to conceive, especially if reproductive assistance is necessary. Accepting the desire to become parents and dealing with the underlying motives as well as the psychosocial situation in an empa- thic way enables couples to see obstacles as well as to develop alternative perspecti- ves if this wish cannot be realized. Frustration, strains and disappointment may accompany unsuccessful treatment cycles or premature termination of pregnancy. Psychiatric co-morbidities in one or both partners (i. Professional diagnosis and support is necessary in these cases.

Adoptive transfer of donor-derived virus-specific cytotoxic T lymphocytes is a strategy to restore virus-specific immunity to prevent or treat viral diseases and has been tested in the clinical setting for more than 20 years. Several different groups have used expanded virus-specific T-cell products specific for one or multiple viruses to both reconstitute antiviral immunity after transplantation and to treat active viral infections. Response rates are encouraging, although resistance has been seen when the infused cell population has had restricted specificity or has targeted antigens expressed in donor-infected but not virally infected recipient cells. The goal of current trials is to make this approach more broadly applicable using more rapidly available products from the donor, such as directly selected or briefly expanded cells or closely matched banked cells. Introduction recently, several groups have defined appropriate target antigens for Viral infections can be a major cause of morbidity and mortality in other viruses that cause morbidity and mortality after transplanta- patients with immunodeficiency. The role of T cells in controlling tion, such as adenovirus,8 HHV6,9 BK,10 and VZV. In the 2 decades since the first pepmixes covering whole viral protein has allowed manufacturing reports that donor-derived CMV-specific cytotoxic T cells (CTLs) to be simplified and live viruses eliminated. Recent manufacturing advances have greatly simplified weeks and, in some cases, cloning to ensure that alloreactive cells production so that several approaches are now being evaluated in were eliminated. More recently, several investigators have evalu- late-phase or licensing studies, raising the prospect that adoptive ated shorter ex vivo culture periods of between 7 and 14 days, along transfer of virus-specific CTLs may become a standard of care after with the use of newer cytokine combinations to expand virus- HSCT. In addition, recent studies showing activity of closely specific T cells. For example, Gerdemann et al have used dendritic matched third-party cells have opened the possibility of wider cells nucleofected with DNA plasmids encoding immunogenic EBV application in other patients with immunodeficiency. After primary Two major rapid selection strategies are currently being tested in the stimulation, which is followed by expansion with cytokines and clinical setting (Figure 1) The first is multimer selection, in which repeated stimulation with antigen, virus-specific T cells will be T cells reactive with an immunogenic peptide are selected using expanded and alloreactive T cells should not survive. However, the magnetically labeled peptide multimers. This strategy is only generation of virus-specific CTLs is a challenge when the donor feasible when the donor has a high frequency of T cells reactive lacks viral immunity for the infecting virus or with cord blood 6 with the viral peptide, so it has largely been confined to the latent transplantations in which the immune cells are virus naive. Results have been encouraging, with massive expansion after transfer of small numbers of T cells15,16 and Antigens and APCs this approach is now being tested in a phase 3 randomized trial in the To generate virus-specific T cells ex vivo, it is necessary to know United Kingdom to treat CMV reactivation (NCT01077908). An the immunogenic antigens for the target virus and have a means of advantage to this method is that the use of multimers avoids the use expressing them in an APC with appropriate costimulation to of an APC, but limitations of multimer selection are the large reactivate T cells. The immunodominant antigens have been well volume of blood needed, which generally mandates a pheresis; the defined for the latent herpes viruses such as CMV2 and EBV. Peggs et al used dendritic cells pulsed with CMV antigen derived from a CMV-infected human lung fibroblast cell line, which produced the expansion of a polyclonal CTL product with broad specificity. This experience argues for the use of a broad polyclonal product containing both CD4 and CD8 T cells. Reports of successful treatment of EBV lymphomas arising cytotoxic T cells recognizing an HLA-restricted peptide by incubation after HSCT in 70% of patients who receive donor lymphocyte with an HLA–peptide multimer and then a collection of multimer positive 4 infusion provided a clear rationale for the evaluation of donor EBV T-cells. Donor cells are CTLs to reduce the risk of alloreactivity. Because 95% of the stimulated with antigen and activated cells that secrete IFN- are population is EBV seropositive and the frequency of EBV-specific selected using an immunomagnetic separation device that captures the T cells can be up to 1%, this was an ideal scenario to evaluate the IFN- –secreting T cells specific for the virus. Unlike other viral infections, EBV lymphomas more commonly arise in donor rather than recipient to which the donor has sufficient circulating T cells to allow cells. EBV-specific T cells were generated using repeated stimula- selection; and the risk of viral evasion when only one peptide is tions with irradiated lymphoblastoid lines (LCLs) generated by targeted. Trials de novo GVHD and the main toxicity was inflammatory reactions at have been reported using IFN- capture to select T cells specific for disease sites in 4 patients who were treated with bulky disease. Of 13 patients who received EBV-specific CTL and CD8 T cells recognizing multiple epitopes, thus lowering the when they had established EBV lymphoma, 11 achieved sustained likelihood of virus evasion.

Opportunistic Infections (OIs) CHRISTIAN HOFFMANN In Western industrialized countries, many opportunistic infections (OIs) that in pre- vious years were considered prevalent are now quite rare. This is particularly true for infections associated with severe immunodeficiency such as CMV and MAC. The incidence of these OIs has been reduced to less than one-tenth of their frequency in the pre-HAART era (Brooks 2009, Buchacz 2010). ART has not only decreased the incidence of OIs, but it has also changed the course of OIs considerably. In the early years of the AIDS epidemic, the life expectancy of individuals diagnosed with their first AIDS-defining illness was at most two to three years. Today, however, many patients live with AIDS for 15 years or longer. In our own clinical study of 144 patients with cerebral toxoplasmosis, data from 1990–1993 indicated a 5-year survival rate of 8%; it climbed to 30% by 1994–1996, and to 80% since 1997 (Hoffmann 2007). Up to 90% of patients who develop AIDS or severe opportunistic infections are unaware of their HIV status. Typically, these patients seek medical attention late, when their overall health condition is serious. Since AIDS remains life-threatening, every HIV clinician should be familiar with the diagnosis of OIs and their respective therapies. Even with recent improvements, many challenges still exist. First, there is still no adequate treatment available for diseases such as PML or cryptosporidio- sis. Second, resistance to treatment has become an increasing problem in OIs such as PCP. Even today, OIs like PML have a mortality rate comparable to that of non-Hodgkin lymphoma (ART-CC 2009). Third, ART does not always lead to immediate improvement. ART may even complicate things, given the atypical course of a variety of diseases with ART (see the separate section on “Immune Reconstitution Inflammatory Syndrome”, IRIS). Fourth, in small HIV centers or regions with low HIV prevalence, diagnostic problems for many OIs may occur, due to a lack of familiarity with and inability to recognize these rarer pathogens. Therefore, it is highly recommended that specimens be sent to specialized reference laboratories. If needed, further advice can be sought from a specialized clinician or a clinical HIV center. The predominant rule for nearly all OIs is that the poorer the immune status of the patient, the earlier the invasive diagnostic procedures should begin. The primary aim should not be to spare patients the unpleasant procedures associated with extensive diagnostic testing. And if the results are inconclusive and nothing is identified the first time, diagnostic tests must be repeated. The second rule is that many OIs can be excluded if the immune status is known. Table 1 indicates the CD4 cut-off values and the rates of certain OIs. The third OI rule is that if ART is not already in place, it should be started as quickly as possible. Immune reconstitution is the best protection against relapses or other OIs. For patients with OIs such as PML or cryptosporidiosis, which have no specific therapy, starting ART is the best hope. Especially in these cases there is no time to waste.
