The CD4/CD8 ratio in HIV-infected subjects is independently associated with T-cell activation despite long-term viral suppression. J Infect 2012; 66:57-66. [PMID: 23046968 DOI: 10.1016/j.jinf.2012.09.013] [Citation(s) in RCA: 101] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2012] [Revised: 09/27/2012] [Accepted: 09/28/2012] [Indexed: 11/21/2022]
Abstract
OBJECTIVES HIV-infected subjects on antiretroviral therapy often fail to normalize the CD4/CD8 ratio despite CD4 count normalization. We aimed to analyze the biological significance of this finding. METHODS Cross-sectional analysis in 20 HIV-infected subjects on stable triple-ART, plasma HIV RNA <40 copies/mL for at least 2 years and CD4 count >350 cells/mm(3). Laboratory measurements included T-cell activation (HLADR(+), CD38(+)) and senescence (CD57(+)), lipopolysaccharide (LPS), sCD14 and the HIV latent reservoir (number of latently infected memory CD4 cells carrying replication-competent virus). RESULTS CD4/CD8 ratio was positively correlated with CD4 nadir (r = 0.468, p = 0.038) and accumulated ART exposure (r = 0.554, p = 0.0011), and negatively with viral load before ART initiation (r = -0.547, p = 0.013), CD4(+)HLADR(+)CD38(+) T-cells (r = -0.428, p = 0.086) and CD8(+)CD57(+) T-cells (r = -0.431, p = 0.084). No associations with LPS, sCD14 or HIV latent reservoir were found. After the multivariate analyses, the CD4/CD8 ratio remained independently associated with CD4(+)HLADR(+)CD38(+) T-cells and CD8(+)HLADR(+) T-cells. CONCLUSIONS In our study in subjects on suppressive ART the CD4/CD8 ratio was independently associated with T-cell activation. Our results must be confirmed in larger studies, as this parameter might be a useful clinical tool to identify subjects with ongoing immune activation despite long-term viral suppression.

Abstract
PURPOSE OF REVIEW To estimate the impact of highly effective antiretroviral therapy (ART) on the incidence and prognosis of Hodgkin lymphoma among people with human immunodeficiency virus infection or AIDS (PWHA). RECENT FINDINGS Age-adjusted incidence of Hodgkin lymphoma in PWHA is unchanged and is still five-fold to fifteen-fold higher than in the general population. Aging of the PWHA population with ART may account for increasing numbers of Hodgkin lymphoma cases. CD4 cell count has a complex relationship to Hodgkin lymphoma risk in PWHA. Depending on the time of measurement, Hodgkin lymphoma risk is highest with 50-249 CD4 cells/μl, and falling CD4 count on ART may be a harbinger of Hodgkin lymphoma onset. HIV load appears irrelevant to Hodgkin lymphoma. For obscure reasons, Hodgkin lymphoma risk may be elevated soon after starting ART, but the risk is probably modestly reduced with 6 or more months on ART. For PWHA who develop Hodgkin lymphoma, ART and ABVD chemotherapy can be administered safely, with one recent study demonstrating equivalent outcomes for HIV-positive and HIV-negative Hodgkin lymphoma patients. SUMMARY Vigilance for Hodgkin lymphoma is needed for immune-deficient PWHA, including those on ART. ART with opportunistic infection prophylaxis enables the delivery of effective chemotherapy for Hodgkin lymphoma, leading to a good prognosis.

Abstract
Hodgkin's lymphoma represents one of the most frequent lymphoproliferative syndromes, especially in young population. Although HL is considered one of the most curable tumors, a sizeable fraction of patients recur after successful upfront treatment or, less commonly, are primarily resistant. This work tries to summarize the data on clinical, histological, pathological, and biological factors in HL, with special emphasis on the improvement of prognosis and their impact on therapeutical strategies. The recent advances in our understanding of HL biology and immunology show that infiltrated immune cells and cytokines in the tumoral microenvironment may play different functions that seem tightly related with clinical outcomes. Strategies aimed at interfering with the crosstalk between tumoral Reed-Sternberg cells and their cellular partners have been taken into account in the development of new immunotherapies that target different cell components of HL microenvironment. This new knowledge will probably translate into a change in the antineoplastic treatments in HL in the next future and hopefully will increase the curability rates of this disease.

Abstract
A nested case-control study was performed within the Italian cohort of naïve to antiretroviral human immunodeficiency virus (HIV) patients (ICONA) cohort to evaluate the role of serum free light chains (sFLC) in predicting non-Hodgkin's lymphoma (NHL) and Hodgkin lymphoma (HL) in HIV-infected individuals. Of 6513 participants, 86 patients developed lymphoma and 46 of these (NHL, 30; HL, 16) were included in this analysis having stored prediagnostic blood. A total of 46 serum case samples matched 1:1 to lymphoma-free serum control samples were assayed for κ and λ sFLC levels and compared by using conditional logistic regression. Because the polyclonal nature of free light chains (FLCs) was the focus of our study, we introduced the k + λ sum as the measurement of choice and as the primary variable studied. κ + λ sFLC values were significantly higher in patient with lymphoma than in controls, especially when considering samples stored 0-2-year period before the lymphoma diagnosis. In the multivariable analysis, the elevation of sFLC predicted the risk of lymphoma independently of CD4 count, (odd ratio of 16.85 for k + λ sFLC >2-fold upper normal limit (UNL) vs. normal value). A significant reduction in the risk of lymphoma (odd ratio of 0.07 in model with k + λ sFLC) was found in people with low sFLC and undetectable HIV viremia lasting more than 6 months. Our analysis indicates that an elevated polyclonal sFLC is a strong and sensitive predictor of the risk of developing lymphomas, and it is an easy to measure biomarker that merits consideration for introduction in routine clinical practice in people with HIV.

Abstract
Epstein-Barr virus (EBV) is associated with several types of cancers including Hodgkin's lymphoma (HL) and nasopharyngeal carcinoma (NPC). EBV-encoded latent membrane protein 1 (LMP1), a multifunctional oncoprotein, is a powerful activator of the transcription factor NF-κB, a property that is essential for EBV-transformed lymphoblastoid cell survival. Previous studies reported LMP1 sequence variations and induction of higher NF-κB activation levels compared to the prototype B95-8 LMP1 by some variants. Here we used biopsies of EBV-associated cancers and blood of individuals included in the Swiss HIV Cohort Study (SHCS) to analyze LMP1 genetic diversity and impact of sequence variations on LMP1-mediated NF-κB activation potential. We found that a number of variants mediate higher NF-κB activation levels when compared to B95-8 LMP1 and mapped three single polymorphisms responsible for this phenotype: F106Y, I124V and F144I. F106Y was present in all LMP1 isolated in this study and its effect was variant dependent, suggesting that it was modulated by other polymorphisms. The two polymorphisms I124V and F144I were present in distinct phylogenetic groups and were linked with other specific polymorphisms nearby, I152L and D150A/L151I, respectively. The two sets of polymorphisms, I124V/I152L and F144I/D150A/L151I, which were markers of increased NF-κB activation in vitro, were not associated with EBV-associated HL in the SHCS. Taken together these results highlighted the importance of single polymorphisms for the modulation of LMP1 signaling activity and demonstrated that several groups of LMP1 variants, through distinct mutational paths, mediated enhanced NF-κB activation levels compared to B95-8 LMP1.

Abstract
BACKGROUND Few studies have compared cancer risk between HIV-infected individuals and a demographically similar HIV-uninfected internal comparison group, adjusting for cancer risk factors. METHODS We followed 20,775 HIV-infected and 215,158 HIV-uninfected individuals enrolled in Kaiser Permanente (KP) California for incident cancer from 1996 to 2008. Rate ratios (RR) were obtained from Poisson models comparing HIV-infected (overall and stratified by recent CD4 count and HIV RNA) with HIV-uninfected individuals, adjusted for age, sex, race/ethnicity, calendar period, KP region, smoking, alcohol/drug abuse, and overweight/obesity. RESULTS We observed elevated RRs for Kaposi sarcoma (KS; RR = 199; P < 0.001), non-Hodgkin lymphoma (NHL; RR = 15; P < 0.001), anal cancer (RR = 55; P < 0.001), Hodgkin lymphoma (HL; RR = 19; P < 0.001), melanoma (RR = 1.8; P = 0.001), and liver cancer (RR = 1.8; P = 0.013), a reduced RR for prostate cancer (RR = 0.8; P = 0.012), and no increased risk for oral cavity/pharynx (RR = 1.4; P = 0.14), lung (RR = 1.2; P = 0.15), or colorectal (RR = 0.9; P = 0.34) cancers. Lung and oral cavity/pharynx cancers were elevated for HIV-infected subjects in models adjusted only for demographics. KS, NHL, anal cancer, HL, and colorectal cancer had significant (P < 0.05) trends for increasing RRs with decreasing recent CD4. The RRs for lung and oral cavity/pharynx cancer were significantly elevated with CD4 < 200 cells/μL and for melanoma and liver cancer with CD4 < 500 cells/μL. Only KS and NHL were associated with HIV RNA. CONCLUSION Immunodeficiency was positively associated with all cancers examined except prostate cancer among HIV-infected compared with HIV-uninfected individuals, after adjustment for several cancer risk factors. IMPACT Earlier antiretroviral therapy initiation to maintain high CD4 levels might reduce the burden of cancer in this population.

Abstract
The eruption of Kaposi sarcoma (KS) and aggressive non-Hodgkin lymphoma (NHL) in young homosexual men in 1981 in the West heralded the onset of the human immunodeficiency virus (HIV) infection epidemic, which remains one of the biggest challenges to global public health and science ever. Because KS and NHL were increased >10,000 and 50-600 times, respectively, with HIV, they were designated AIDS defining cancers (ADC). Cervical cancer (CC), increased 5-10 times was also designated as an ADC. A few other cancers are elevated with HIV, including Hodgkin lymphoma (10 times), anal cancer (15-30 times), and lung cancer (4 times) are designated as non-AIDS defining cancers (NADCs). Since 1996 when combination antiretroviral therapy (cART) became widely available in the West, dramatic decreases in HIV mortality have been observed and substantial decrease in the incidence of ADCs. Coincidentally, the burden of NADCs has increased as people with HIV age with chronic HIV infection. The impact of HIV infection on cancer in sub-Saharan Africa, where two thirds of the epidemic is concentrated, remains poorly understood. The few studies conducted indicate that risks for ADCs are also increased, but quantitatively less so than in the West. The risks for many cancers with established viral associations, including liver and nasopharynx, which are found in Africa, do not appear to be increased. These data are limited because of competing mortality, and cancer is under diagnosed, pathological confirmation is rare, and cancer registration not widely practiced. The expansion of access to life-extending cART in sub-Saharan Africa, through programs such as the Global Fund for AIDS, Malaria, and Tuberculosis and the US President's Emergency Program for AIDS Relief (PEPFAR), is leading to dramatic lengthening of life of HIV patients, which will likely influence the spectrum and burden of cancer in patients with HIV. In this paper, we review current literature and explore merits for integrating cancer research in established HIV programs to obtain timely data about the incidence and burden of cancer in HIV-infected persons in Africa.

Abstract
We evaluated factors associated with normalization of the absolute CD4+ T-cell counts, per cent CD4+ T cells and CD4+/CD8+ T-cell ratio. A multicentre observational study was carried out in patients with sustained HIV-RNA <50 copies/mL. Outcomes were: CD4-count >500/mm(3) and multiple T-cell marker recovery (MTMR), defined as CD4+ T cells >500/mm(3) plus%CD4 T cells >29%plus CD4+/CD8+ T-cell ratio >1. Kaplan-Meier survival analysis and Cox regression analyses to predict odds for achieving outcomes were performed. Three hundred and fifty-two patients were included and followed-up for a median of 4.1 (IQR 2.1-5.9) years, 270 (76.7%) achieving a CD4+ T-cell count >500 cells/mm(3) and 197 (56%) achieving MTMR. Using three separate Cox models for both outcomes we demonstrated that independent predictors were: both absolute CD4+ and CD8+ T-cell counts, %CD4+ T cells, a higher CD4+/CD8+ T-cell ratio, and age. A likelihood-ratio test showed significant improvements in fitness for the prediction of either CD4+ >500/mm(3) or MTMR by multivariable analysis when the other immune markers at baseline, besides the absolute CD4+ count alone, were considered. In addition to baseline absolute CD4+ T-cell counts, pretreatment %CD4+ T cells and the CD4+/CD8+ T-cell ratio influence recovery of T-cell markers, and their consideration should influence the decision to start antiretroviral therapy. However, owing to the small sample size, further studies are needed to confirm these results in relation to clinical endpoints.

Abstract
The risk of Hodgkin lymphoma (HL) is increased in patients infected with HIV-1. We studied the incidence and outcomes of HL, and compared CD4+ T-cell trajectories in HL patients and controls matched for duration of combination antiretroviral therapy (cART). A total of 40 168 adult HIV-1–infected patients (median age, 36 years; 70% male; median CD4 cell count, 234 cells/μL) from 16 European cohorts were observed during 159 133 person-years; 78 patients developed HL. The incidence was 49.0 (95% confidence interval [CI], 39.3-61.2) per 100 000 person-years, and similar on cART and not on cART (P = .96). The risk of HL declined as the most recent (time-updated) CD4 count increased: the adjusted hazard ratio comparing more than 350 with less than 50 cells/μL was 0.27 (95% CI, 0.08-0.86). Sixty-one HL cases diagnosed on cART were matched to 1652 controls: during the year before diagnosis, cases lost 98 CD4 cells (95% CI, −159 to −36 cells), whereas controls gained 35 cells (95% CI, 24-46 cells; P < .0001). The incidence of HL is not reduced by cART, and patients whose CD4 cell counts decline despite suppression of HIV-1 replication on cART may harbor HL.

Abstract
Hodgkin lymphoma (HL) incidence with HIV infection may have increased with the introduction of combination antiretroviral therapy (cART), suggesting that immune reconstitution may contribute to some cases. We evaluated HL risk with cART during the first months of treatment. With 187 HL cases among 64 368 HIV patients in France, relative rates (RRs) and 95% confidence intervals (CIs) of HL were estimated using Poisson models for duration of cART, CD4 count, and HIV load, with and without adjustment for demographic/clinical covariates. HL risk was unrelated to cART use overall, but it was related to time intervals after cART initiation (P = .006). Risk was especially and significantly elevated in months 1-3 on cART (RR 2.95, CI 1.64-5.31), lower in months 4-6 (RR 1.63), and null with longer use (RR 1.00). CD4 count was strongly associated with HL risk (P < 10⁻⁶), with the highest HL incidence at 50-99 CD4 cells/mm³. With adjustment for CD4 count and covariates, HL risk was elevated, but not significantly (RR 1.42), in months 1-3 on cART. HIV load had no added effect. HL risk increased significantly soon after cART initiation, which was largely explained by the CD4 count. Further studies of HIV-associated HL are needed.

Abstract
BACKGROUND Cancer is now the leading cause of death in persons with HIV. In this study, we gathered current epidemiological data on Aids-defining (AD) and non-Aids-defining (NAD) malignancies among HIV-positive patients in Germany. METHODS From 2000 to 2007, all 35 specialized HIV outpatient clinics and 189 HIV ambulatory care centers in Germany were contacted and asked to fill out a structured questionnaire on the incidence of malignancies in HIV-positive patients during multiple periods of observation. RESULTS 552 evaluable data sets were reported. 253 (45.8%) of the reported malignancies were AD. Among the 299 cases (54.2%) of NAD malignancies, there were 214 solid tumors, including 71 anal carcinomas (23.7% of all NAD malignancies), and 85 hematopoietic malignancies, including 29 cases of Hodgkin`s lymphoma (9.7% of all NAD malignancies). The high percentage of NAD malignancy remained constant throughout the entire period of the study. Only a single case of primary cerebral lymphoma was reported after 2001. The number of patients with Hodgkin`s lymphoma rose steadily from 2000 to 2007. CONCLUSION The spectrum of HIV-associated malignancies has changed since the early days of the HIV epidemic. In Germany, NAD malignancies have become more common than AD malignancies. In particular, anal carcinoma and Hodgkin's lymphoma are much more common among persons with HIV than in the general population. Persons with HIV need more intensive preventive care for cancer than non-infected persons do.

Abstract
Presentation of Hodgkin lymphoma (HL) is distinctive in the infected individual being more advanced, accompanied by B symptoms and the presence of extranodal disease particularly lymphadenopathy of the head and neck. Bone marrow involvement may be found in over 50% of cases. Virtually all co express gamma-herpesvirus. Phenotypically there is prominence of the mixed-cellularity and lymphocyte depleted histopathologic subtypes that define an aggressive clinical course in comparison to other variants. Prior to the induction of cART, median survival was only 1-2 years. Notably the first chemotherapy trial using ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) in 21 patients, without treating the viral infection, resulted in a 43% complete remission rate accompanied by severe haematological toxicities but did not extend median survival with this being 1.5 years matching the negative cases. Significant change accompanied concomitant anti-retroviral therapy that could be given safely even with dose intensive regimens exemplified by BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) in 12 patients or the Stanford V regimen (doxorubicin, vinblastine, mechlorethamine, etoposide, vincristine, bleomycin, prednisone) coupled with involved-field radiation for bulky disease studied in 59 patients. BEACOPP extended overall survival (OS) to 83% at 2 years. A similar trend was seen when using the Stanford V regimen with an OS rate of 51% at 3 years, disease-free survival (DFS) of 68% and freedom from progression (FFP) in 60%. Additional benefits accrued from supportive care with stimulatory peptides such as G-CSF and when combined with bacterial prophylaxis results approached that found in the uninfected reference group. Current consensus holds this particular lymphoma as still among the non-AIDS defining cancers being lung, stomach, liver or anal despite these having recently gained more attention as several of these neoplasms may be occurring more commonly in the era of cART. While the relative risk of developing a non-AIDS-defining neoplasm in HIV-infected persons on the average is 2-3 times, the risk for developing HL in HIV-infected cases impressively ranges between 5 and 25 times when compared to the general population. Based on the precedent in which Kaposi sarcoma and the non-Hodgkin lymphomas distinctively alter the course of this retroviral infection in a way indistinguishable from concurrent Hodgkin lymphoma we propose that this entity be similarly regarded and the hypothesis tested in large randomised prospective study.

Abstract
PURPOSE OF REVIEW In this review, we update investigations related to cancer biomarkers in HIV-infected populations. RECENT FINDINGS CD4 lymphocyte count is associated with primary central nervous system lymphoma (PCNSL), systemic non-Hodgkin's lymphoma (NHL) (except perhaps for Burkitt lymphoma), Kaposi's sarcoma, cervical cancer, and anal cancer. HIV load is associated with Burkitt lymphoma and systemic NHL (but not PCNSL), with Kaposi's sarcoma and with anal cancer. CD40 ligand incorporated into the HIV envelope and expression of activation-induced cytidine deaminase may help explain the relationship between HIV load and Burkitt lymphoma. Genetic polymorphisms have been identified that are linked to lymphoma in HIV patients. B-cell activation as manifest in immunoglobulin light chain production may be an important marker for NHL risk. Cytokines and related molecules (IL10, sCD30) may identify patients at high risk for NHL. Epstein-Barr virus (EBV) in cerebrospinal fluid (CSF) is useful as a marker for PCNSL, although with the falling incidence of PCNSL, the specificity of the test has been called into question. EBV and Kaposi's sarcoma-associated herpesvirus (KSHV) have not yet emerged as especially promising markers of risk for either lymphoma or Kaposi's sarcoma. SUMMARY CD4 lymphocyte count, HIV load, germline genetic polymorphisms, cytokine and related molecules, and immunoglobulin light chains all show increasing promise as biomarkers of malignancy in HIV patients.

Abstract
BACKGROUND The overall burden of cancer may increase as individuals with acquired immunodeficiency syndrome (AIDS) live longer because of highly active antiretroviral therapy (HAART), which has been widely available since 1996. METHODS A population-based, record-linkage study identified cancers in 472,378 individuals with AIDS from 1980 to 2006. By using nonparametric competing-risk methods, the cumulative incidence of cancer was estimated across 3 calendar periods (AIDS onset in 1980-1989, 1990-1995, and 1996-2006). RESULTS Measured at 5 years after AIDS onset, the cumulative incidence of AIDS-defining cancer (ADC) declined sharply across the 3 AIDS calendar periods (from 18% in 1980-1989, to 11% in 1990-1995, to 4.2% in 1996-2006 [ie, the HAART era]). The cumulative incidence of Kaposi sarcoma declined from 14.3% during 1980 to 1989, to 6.7% during 1990 to 1995, and to 1.8% during 1996 to 2006. The cumulative incidence of non-Hodgkin lymphoma (NHL) declined from 3.8% during 1990 through 1995 to 2.2% during 1996 through 2006; during the HAART era, NHL was the most common ADC (53%). The cumulative incidence of non-AIDS-defining cancer (NADC) increased from 1.1% to 1.5% with no change thereafter (1%; 1996-2006), in part because of declines in competing mortality. However, cumulative incidence increased steadily over time for specific NADCs (anal cancer, Hodgkin lymphoma, and liver cancer). The cumulative incidence of lung cancer increased from 0.14% during 1980 to 1989 to 0.32% during 1990 to 1995, and no change was observed thereafter. CONCLUSIONS Dramatically declining cumulative incidence was noted in 2 major ADCs (Kaposi sarcoma and NHL), and increases were observed in some NADCs (specifically, cancers of the anus, liver, and lung and Hodgkin lymphoma). As HIV/AIDS is increasingly managed as a chronic disease, greater attention should be focused on cancer screening and prevention.

Abstract
BACKGROUND Persons living with AIDS today remain at elevated cancer risk. Highly active antiretroviral therapy (HAART), widely available since 1996, prolongs life, but immune function is not fully restored. We conducted this study to assess long-term cancer risk among persons with AIDS relative to the general population and the impact of HAART on cancer incidence. METHODS Records of 263 254 adults and adolescents with AIDS (1980-2004) from 15 US regions were matched to cancer registries to capture incident cancers during years 3 through 5 and 6 through 10 after AIDS onset. Standardized incidence ratios (SIRs) were used to assess risks relative to the general population. Rate ratios (RRs) were used to compare cancer incidence before and after 1996 to assess the impact of availability of HAART. RESULTS Risk was elevated for the 2 major AIDS-defining cancers: Kaposi sarcoma (SIRs, 5321 and 1347 in years 3-5 and 6-10, respectively) and non-Hodgkin lymphoma (SIRs, 32 and 15). Incidence of both malignancies declined in the HAART era (1996-2006). Risk was elevated for all non-AIDS-defining cancers combined (SIRs, 1.7 and 1.6 in years 3-5 and 6-10, respectively) and for the following specific non-AIDS-defining cancers: Hodgkin lymphoma and cancers of the oral cavity and/or pharynx, tongue, anus, liver, larynx, lung and/or bronchus, and penis. Anal cancer incidence increased between 1990-1995 and 1996-2006 (RR, 2.9; 95% confidence interval [CI], 2.1-4.0), as did that of Hodgkin lymphoma (RR, 2.0; 95% CI, 1.3-2.9). CONCLUSION Among people who survived for several years or more after an AIDS diagnosis, we observed high risks of AIDS-defining cancers and increasing incidence of anal cancer and Hodgkin lymphoma.

Abstract
BACKGROUND The incidence of Kaposi sarcoma (KS) and non-Hodgkin lymphoma (NHL) among human immunodeficiency virus (HIV)-infected individuals declined after the introduction of highly active antiretroviral therapy (HAART) in the mid-1990s, but the cancer risk associated with HIV infection during the HAART era remains to be clarified. METHODS Cancer incidence among HIV-infected and HIV-uninfected participants in the Multicenter AIDS (acquired immunodeficiency syndrome) Cohort Study (MACS) between 1984 and 2007 was compared with the expected incidence using US population-based data from the Surveillance, Epidemiology, and End Results (SEER) program. Age- and race-adjusted cancer incidence rates were also compared HIV by status and over time within the MACS. Exact statistical methods were used for all analyses. RESULTS A total of 933 incident cancers were observed during 77,320 person-years of follow-up. Compared with SEER, MACS HIV-infected men had significantly (P<.05) elevated rates of KS (standardized incidence ratio [SIR], 139.10), NHL (SIR, 36.80), Hodgkin lymphoma (HL)(SIR, 7.30), and anal cancer (SIR, 25.71). Within MACS, HIV infection was found to be independently associated with each of these cancers across the entire follow-up period, and KS (incidence rate ratio [IRR], 54.93), NHL (IRR, 11.18), and anal cancer (IRR, 18.50) were each found to be significantly elevated among HIV-infected men during the HAART era. Among these men, the incidence of KS and NHL declined (IRR, 0.13 and 0.23, respectively), the incidence of anal cancer increased (IRR, 5.84), and the incidence of HL remained statistically unchanged (IRR, 0.75) from the pre-HAART to the HAART era. CONCLUSIONS Cancer risk remains elevated among HIV-infected men who have sex with men, highlighting the continuing need for appropriate cancer screening in this population.

Abstract
OBJECTIVE To describe features of reactive haemophagocytic syndrome (RHS) in HIV-1-infected adult patients. To compare characteristics of patients with malignancy-associated RHS and infection-associated RHS. DESIGN AND SETTING Retrospective study in three departments of Infectious Diseases/Internal Medicine at three French tertiary centres. PATIENTS AND METHODS Medical charts of HIV-1-infected adult patients and RHS seen between January 2006 and December 2007 were reviewed. Demographic, clinical and laboratory data obtained at the time of RHS episode were compared between patients with malignancy-associated RHS and infection-associated RHS using non-parametric tests. The overall survival was assessed using the Kaplan-Meier method. RESULTS Fifty-eight HIV-1-infected patients were diagnosed with RHS [certain RHS n = 43, possible RHS n = 15, median (range) age 42 (23-85) years, men 76%]. At time of RHS, the median duration of HIV infection was 4 (0-22) years and 57% received HAART. The median CD4 lymphocyte count was 91 (2-387)/microl and 35% of patients had a plasma HIV-1 RNA less than 50 copies/ml. Underlying haemopathy/malignancy (Hodgkin lymphoma n = 10) or infection (tuberculosis n = 9, cytomegalovirus infection n = 5) were evidenced for 31 and 23 patients, respectively. Patients with haemopathy/malignancy-associated RHS presented more frequently with splenomegaly (97 vs. 70%, P < 0.01), lower aspartate aminotransferase (36 vs. 84 UI/l, P < 0.01) and lactate dehydrogenase (530 vs. 911 UI/l, P < 0.01) levels and CD8 cell count (234 vs. 588/microl, P < 0.01). Eighteen (31%) patients died. The overall survival was not statistically different between the two groups (P = 0.68). CONCLUSION In the HAART era, RHS is frequently associated with underlying haemopathy/malignancy, especially Hodgkin lymphoma. The prognosis remains poor but seems, however, better than in the pre-HAART era.

Abstract
Analysis of cancer risk in primary immune deficiency (PID) offers insight into the relationship between immune function and cancer. Data on Australian patients (n = 1132) notified voluntarily to the Australasian Society of Clinical Immunology and Allergy PID Registry (1990-2008) were linked with national death and cancer registries. Person-years of follow-up commenced from up to 15 years before registration on the PID Registry or January 1982, the inception of national cancer registration. Site-specific, 5-year age-, sex-, calendar year-, and state-standardized incidence ratios (SIRs) with 95% confidence intervals (95% CIs) were calculated for all cancers except nonmelanocytic skin cancer. During an average of 16 person-years follow-up, a 1.6-fold excess relative risk of cancer was observed (n = 58; SIR 1.60, 95% CI 1.22-2.07) for all PID combined. Relative risk was increased for non-Hodgkin lymphoma (n = 16; SIR 8.82, 95% CI 5.04-14.30), leukemia (n = 4; SIR 5.36, 95% CI 1.46-13.73), and stomach cancer (n = 3; SIR 6.10, 95% CI 1.26-17.84). Excess cancer risk was observed for predominantly antibody deficiencies and other well-defined immunodeficiency syndromes. Results suggest that predominantly antibody deficiencies may be associated with a narrower range of solid cancers than immunodeficiency characterized by predominantly T-cell deficiency, such as iatrogenic and HIV-related immunodeficiency, although this requires confirmation in larger cohorts.

Abstract
OBJECTIVE To describe changes in cancer incidence in people with HIV in Australia since the introduction of highly active antiretroviral therapy (HAART). DESIGN Population-based, retrospective cohort study of people with HIV (n = 20 232) using data linkage between national registers of HIV/AIDS and cancer in 1982-2004. METHODS Age-adjusted and sex-adjusted incidence rate ratios with 95% confidence intervals were calculated to compare site-specific cancer incidence during the early (1996-1999) and late (2000-2004) HAART periods with that prior to HAART (1982-1995). Five-year age-specific, sex-specific, calendar year-specific, and state-specific standardized incidence ratios with 95% confidence interval were also calculated for each period. RESULTS Incidence of Kaposi sarcoma and non-Hodgkin lymphoma declined significantly (Ptrend < 0.001). Incidence of Hodgkin lymphoma was significantly higher during the early-HAART period (incidence rate ratio 2.34, 95% confidence interval 1.19-4.63) but declined thereafter (Pdiff = 0.014). Incidence of anal cancer was unchanged (Ptrend = 0.451) and remained raised more than 30-fold. Incidence declined significantly for melanoma (Ptrend = 0.041) and prostate cancer (Ptrend = 0.026), and, during the late-HAART period, was lower than in the general population for both cancers. Incidence of colorectal cancer was consistently lower than in the general population. CONCLUSION Incidence of Kaposi sarcoma and non-Hodgkin lymphoma has continued to decline among people with HIV in Australia, though it remains very substantially elevated. Incidence of Hodgkin lymphoma may now also be declining. Incidence of anal cancer has remained stable, and it is now the third most common cancer in HIV-infected Australians. Reasons for the reduced incidence of colorectal and prostate cancer, and more recently of melanoma, are unclear.
