HIV and Wanting to be a Parent ULRIKE SONNENBERG-SCHW AN, MICHAEL W EIGEL Introduction For a growing number of men and women living with HIV/AIDS the perspective of parenthood is an important part in their planning of the future. Procreation without risk, or at very low risk of infection for the uninfected partner or prospective child, is achievable for couples in which one or both partners are HIV-infected. In an increa- sing number of countries reproductive counselling and/or support is provided to couples affected by HIV. Procreative options for HIV-affected couples vary from unprotected intercourse to several techniques of assisted reproduction, donor insemination or adoption. In view of the strongly decreased risk of transmission with undetectable viral load, concep- tion via intercourse without condoms has increasingly become an option under certain circumstances. This has been greatly influenced by the “EKAF Statement” (Vernazza 2008, see also ART chapter) regarding the unlikeliness of HIV transmission while on effective ART. In January 2008, the EKAF (Swiss Commission on AIDS-related issues) stated that physicians could inform their patients about a negligible sexual transmission risk if three conditions are met: • The HIV-infected patient is on a physician-monitored ART and is adherent • Plasma viral load has consistently been undetectable for more than 6 months • No sexually transmitted diseases are present in either of the partners The statement also emphasized that only the HIV-negative partners can decide for themselves whether they want to stop using condoms with their seropositive partner.

Maraviroc is the first discount 5 mg nebivolol free shipping, FDA-approved CCR5 inhibitor and can be given to patients after a tropism check buy nebivolol 5mg online. CCR5 inhibitors have also been successfully given as microbicides in non-human primates and could represent an option for prevention of infection (Veazey 2005). In vitro studies as well as experiments using SCID mice, however, do suggest that blockade of CCR5-using isolates may alter their tropism towards increased usage of CXCR4 (De Clercq 2001). In this respect, the “second Berlin patient” is fascinating. This HIV-infected patient developed acute myeloic leukemia and needed bone morrow transplantation. He was transplanted from a donor who carried the homozygous delta32 mutation of the CCR5 receptor (Hütter 2009). After transplantation, antiretroviral treatment was stopped and HIV remained undetectable in this patient. Years later, a thorough search for HIV was conducted in the patient and none was found (Allers 2011). Therefore the patient is thought to be cured of HIV. This case has led to an intense search for other ways to delete the CCR5 receptor. Although the therapeutic use of chemokine receptor blockers seems promising, a lot of questions still remain unanswered. Chemokine analogues such as AOP-Rantes theoretically also bind to other chemokine receptors. In knockout mice it was demon- strated that the absence of CXCR4 or SDF-1 is associated with severe defects in hematopoiesis and in cerebellar development (Zou 1997). Currently, it remains unclear whether the blockade of CXCR4 in postnatal or adult individuals may affect other organ systems. Post-fusion events Following membrane fusion the viral capsid uncoats into the cytoplasm of the target cell. Alternatively, receptor-mediated endocytosis and dynamin-dependent fusion with intracellular compartments (Miyauchi 2009) can lead to viral inoculation. HIV can enter into rhesus lymphocytes but replication is stopped before or during early reverse transcription. This intracellular blockade is mediated by a cellular factor, TRIM5 (tripartite motif 5 ), a component of cytoplasmic bodies whose primary function is not yet understood. TRIM5 from various species exhibits differential inhibition on various retroviruses. For example, TRIM5 from rhesus macaques, TRIM5 rh, more profoundly inhibits HIV replication than human TRIM5 , whereas SIV (simian immunodeficiency virus) which naturally infects Old World monkeys, is less susceptible to either form of TRIM5 , thus explaining in part the species speci- ficity of HIV for human cells (Stremlau 2004). TRIM5 from human cells or non- human primates is able to inhibit replication of other lentiviruses and represents a novel cellular resistance factor whose definitive biological significance has yet to be fully characterized. TRIM5 serves as a mechanism for intracellular recognition and activation of the unspecific immune response (Pertel 2011), but it is unclear how exactly TRIM5 blocks reverse transcription. It has been hypothesized that TRIM5 30 The Basics Figure 5: Life cycle of HIV within the host cell interferes with the incoming virus capsid protein, targeting it for ubiquitination and proteolytic degradation. HIV-1 entry into quiescent T cells is comparable to HIV-1 entry into activated T cells, but synthesis of HIV-1 DNA remains incomplete in quiescent cells (Zack 1990). The conversion of viral RNA into proviral DNA, mediated by the viral enzyme reverse transcriptase (RT), occurs in the cytoplasm of the target cell and is a crucial step within the viral replication cycle (Fig. Blockade of the RT as therapeutic inter- vention has long been a therapeutic principle. HIV-1 enters into quiescent T cells and reverse transcription may result in the accu- mulation of proviral, non-integrating HIV DNA. However, cellular activation is necessary for integration of the proviral HIV DNA into the host cell genome after transportation of the pre-integration complex into the nucleus. Cellular activation may occur in vitro after stimulation with antigens or mitogens. In vivo, activation of the immune system is observed after antigen contact or vaccination or during an opportunistic infection. In addition, evidence is emerging that HIV-1 gp120 itself may activate the infecting cell to enhance integration. Besides monocytes, macrophages and microglial cells, latently infected quiescent CD4 T cells that contain non-integrated proviral HIV DNA represent important long-lived cellular reservoirs of HIV (Chun 1997), and cellular microRNAs contribute to HIV-1 latency in resting primary CD4 T lymphocytes (Huang 2007). Since natural HIV-1 infection is charac- terized by continuing cycles of viral replication in activated CD4 T cells, viral latency in these resting CD4 T cells likely represents an accidental phenomenon and is not likely to be important in the pathogenesis of HIV. This small reservoir of latent provirus in quiescent CD4 T cells gains importance, however, in individuals treated with ART, since the antivirals do not affect non-replicating proviruses – the virus will persist in those cells and be replication-competent to start new rounds of infection if the drugs are stopped. It is the existence of this latent reservoir that has prevented ART from entirely eradicating the virus from infected individuals (Chun 2005). Pathogenesis of HIV-1 Infection 31 For the integration of the proviral DNA into the host genome – the prerequisite for the synthesis of new virions (Zack 1990) – the viral enzyme integrase is needed.
