Ng1 1Department of Radiation Oncology, Brigham and Women’s Hospital, Boston, MA Long-term survivors of Hodgkin lymphoma (HL) are at an increased risk for a range of late complications, with subsequent malignant neoplasm and cardiovascular disease representing the 2 leading causes of death in these patients. Raising awareness, close follow-up, and adoption of selected early-detection and risk-reduction strategies may help to reduce the adverse impact of these late effects on patients. This chapter reviews known long-term complications of HL therapy, risk factors, and the timing of their occurrence. Where available, data on the efficacy of screening for selected late effects of HL are presented. Current evidence-based and consensus-based recommenda- tions on follow-up of long-term HL survivors are also reviewed. As HL therapy evolves over time, late effects and implications on follow-up of patients treated in the contemporary era should be considered and opportunities for future research should be explored. The following sections describe selected Learning Objectives long-term complications and their associated risk factors. The association between use of term HL survivors alkylating chemotherapy for HL therapy and leukemia risk was first recognized in the early 1970s. Over the years, the data on second malignancy after HL have accumulated, with solid tumors account- Introduction ing for the majority of cases of second malignancy after HL. In Long-term Hodgkin lymphoma (HL) survivors are at risk of addition, the relative risks remain significantly elevated at 25 years developing a range of therapy-related complications that may after initial HL diagnosis. These complications have resulted in to solid tumors in HL survivors, although more recent data have an increased mortality among HL survivors.

Quinn1 1Division of Hematology, Cincinnati Children’s Hospital Medical Center, Cincinnati, OH Silent cerebral infarction (SCI) is a highly prevalent and morbid condition in sickle cell disease (SCD). SCI can occur beginning in the first year of life and becomes more common with increasing age. Potentially modifiable risk factors for SCI include anemia and blood pressure. Headache does not appear to be associated with SCI, so neurologically normal children with headache do not necessarily warrant screening MRI for SCI. SCI does affect cognition, but biological determinants of cognition are not more important than socioeconomic factors. The recent identification of acute silent cerebral ischemic events indicates that the total burden of ischemic injury to the brain in SCD is far greater than previously realized. Acute anemic events appear to increase the risk of acute silent cerebral ischemic events and SCI dramatically. The medical management of SCI is not yet defined, but documentation of the presence of SCI may qualify affected individuals for special resources because comprehensive interventions are needed to optimize patients’ academic and vocational outcomes. The goal of this chapter is to ● To summarize the risk factors for SCI in SCD highlight several of the recent advances in our understanding of ● To rank by relative frequency the overt and covert neurologic the frequency, risk factors, correlates, causes, and management events in SCD of SCI.

HIV-2 non-progressors have minimal immune activation; high viral load HIV-2 progressors have higher immune activa- tion levels buy cheap apcalis sx 20mg on-line, similar to or exceeding those in HIV-1 infection (Hegedus 2014) generic 20mg apcalis sx free shipping. In addi- tion, programmed death (PD)-1/PD-L1 molecules, rather than markers of T cell exhaustion, may act as modulators of T cell immune activation, contributing to the slower course of HIV-2 infection (Tendeiro 2012). In most studies, a considerable proportion (up to 40–50% of HIV-2 infection is aviremic (which typically means a viral load of below 100 copies/ml). In many of these patients, however, plasma RNA is detectable by sensitive assays such as quali- tative RT PCR. In contrast, the median proviral HIV-2 DNA is 200 copies/105 PBMC and similar to those with HIV-1 (Popper 2000, Gottlieb 2002, Matheron 2003). Difference in the pathogenicity of HIV-1 and HIV-2 may be explained by differences in viral replication, mainly at late stages after integration and before late transcription (Soares 2012). Despite the lower levels of plasma RNA, HIV-2 is able to establish a stable latent infection in vivo (MacNeil 2007). Patients with higher viral load (>1000 copies/ml) show marked differences compared to patients with low viral load (<100 copies/ml). The latter are mainly non-progres- 516 Other Infections than HIV-1 sors, with low CD4 and CD8 T cell turnover in memory cells, minimal immune acti- vation and a minimal impairment of thymus function (Hegedus 2014). Highly viremic patients display no differences compared to HIV-1-infected patients. Humoral responses in HIV-2 infection appear broader intratype neutralization responses. There is no cross-reactivity between HIV-1 and HIV-2 (Rodriguez 2007). HIV-2 isolates appear to have two mechanisms of immune evasion that are dimin- ished in effectiveness relative to HIV-1: glycan shielding and conformational masking (Kong 2012). Potency and breadth of neutralizing antibodies decrease as the disease progresses. Resistance to antibody neutralization occurs in late stage disease and is usually associated with X4 viral tropism and major changes in V3 sequence and con- formation (Marcelino 2012). Natural killer cell function is well preserved in asymptomatic HIV-2 infection but similar to that of HIV-1 infection when CD4 T cell counts fall (Nuvor 2006). There are also differences with regard to restriction factors such as TRIM5, SAMHD-1 or the APOBEC3F/3G family of deaminase enzymes (Ylinen 2005, Nyamweya 2013, Bertine 2015). Viral factors Viral evolution occurs slowly in HIV-2 infection, which is consistent with the slow disease progression of HIV-2 and supports the notion that viral evolution may be a relevant correlate for disease progression. Longitudinal studies have shown a remark- able stability of env-C2V3 sequences over many years (MacNeil 2007). Accumulation of viral mRNA is attenuated in HIV-2 infection relative to that in HIV-1 infection. The differences in viral mRNA are consistent with the differences in plasma viral loads between HIV-1 and HIV-2 and suggest that lower plasma viral loads, and pos- sibly the attenuated pathogenesis of HIV-2, can be explained by lower rates of viral replication in vivo. Changes in the genome of HIV-2 may have higher consequences on replicative fitness (MacNeil 2007). The multifunctional accessory Nef protein may play an important role in the immunopathogenesis of HIV-2 infection. Nef proteins are able to downregulate the T cell receptor (TCR)-CD3 complex of the infected cell, thereby reducing the poten- tial for deleterious activation. This Nef-mediated downmodulation is higher in HIV-2 infection and may help viremic HIV-2-infected individuals maintain normal CD4 T cell homeostasis by preventing T cell activation and by suppressing the induction of death receptors that may affect the functionality and survival of both virally infected and uninfected bystander cells (Khalid 2012). Dual infection with HIV-1 and HIV-2 Dual infection with HIV-1 and HIV-2 was first confirmed in 1988, but difficulties in distinguishing between dual seropositivity and dual infection have hampered efforts to estimate the prevalence of this phenomenon. As a consequence, studies of clini- cal progression and outcomes are scarce (Raugi 2013). In a systematic review and meta-analysis, patients with dual infection had a similar mortality compared to HIV-1- infected patients which was higher than those of HIV-2-monoinfected persons. There was no evidence that HIV-2 delays progression to death in dually infected individ- uals (Prince 2014). In a cohort study from Senegal, after adjusting for CD4 T cell count, age and sex, HIV-1 RNA levels were significantly higher than HIV-2 levels in semen, cervicovaginal lavage, and oral fluids. Results suggest that with disease progression, HIV-1 outcompetes HIV-2 in dually infected individuals (Raugi 2013).
