The rate of viral rebound after attainment of an HIV load <50 copies/mL according to specific antiretroviral drugs in use: results from a multicenter cohort study.
BACKGROUND: Relatively few data are available on the association between the use of specific antiretroviral drugs and the rate of viral rebound in those attaining a viral load (VL) <50 copies/mL while receiving highly active antiretroviral therapy (HAART). METHODS: Patients achieving a VL <50 copies/mL for the first time while receiving HAART were followed until viral rebound (2 consecutive VLs >500 copies/mL). Pre-HAART antiretroviral-naive patients were analyzed separately from those with nucleoside reverse transcriptase inhibitor (NRTI) experience. RESULTS: Of 3565 suppressed antiretroviral-naive patients, 381 experienced viral rebound (rate, 6.26 events/100 person-years of follow-up [pyrs] [95% confidence interval {CI}, 5.63-6.89 events/100 pyrs]). For those receiving efavirenz, the rate was 4.08 (95% CI, 3.16-5.01) events/pyrs. Compared with this, the rebound rate for those receiving indinavir was 1.52 times higher (rate ratio [RR], 1.52 [95% CI, 0.82-2.84]). RRs (95% CIs) for other drugs were: soft-gel saquinavir, 0.54 (0.07-3.97); nelfinavir, 2.44 (1.68-3.54); indinavir/ritonavir, 1.96 (1.02-3.77); saquinavir/ritonavir, 1.12 (0.48-2.61); lopinavir/ritonavir, 1.23 (0.58-2.59); nevirapine, 1.53 (1.11-2.10); and abacavir, 2.03 (1.26-3.25). Of 810 NRTI-exposed patients, 145 experienced viral rebound (rate, 8.29 [95% CI, 6.94-9.64] events/pyrs). For those receiving efavirenz, the rate was 5.25 (95% CI, 3.11-8.30) events/pyrs. Compared with this, the RRs (95% CIs) were: indinavir, 1.75 (0.82-3.73); hard-gel saquinavir, 3.48 (0.36-33.37); nelfinavir, 2.64 (1.37-5.08); indinavir/ritonavir, 0.32 (0.04-2.49); saquinavir/ritonavir, 0.64 (0.23-1.80); nevirapine, 1.65 (0.90-3.02); and abacavir, 1.82 (0.73-4.52). CONCLUSIONS: We must make comparisons of antiretroviral outcomes in observational data with caution; however, our results suggest that, in those with VLs <50 copies/mL, certain drugs may be associated with higher rebound rates than others.

A prognostic index for systemic AIDS-related non-Hodgkin lymphoma treated in the era of highly active antiretroviral therapy.
BACKGROUND: The established International Prognostic Index for lymphomas has not included patients with systemic AIDS-related non-Hodgkin lymphoma. OBJECTIVE: To establish the most appropriate prognostic index for use in patients with systemic AIDS-related non-Hodgkin lymphoma. DESIGN: A prospective study involving univariate and multivariable analyses of patients with AIDS-related non-Hodgkin lymphoma whose data were used to examine standard and new criteria for survival after diagnosis. SETTING: The Chelsea and Westminster cohort of HIV-1-infected persons. PATIENTS: 9621 HIV-positive patients, 111 in whom AIDS-related non-Hodgkin lymphoma was treated after 1996, in the era of highly active antiretroviral therapy (HAART). INTERVENTION: Cox proportional hazards regression analysis to determine the prognostic significance of multiple clinicopathologic variables. RESULTS: Survival of patients with AIDS-related non-Hodgkin lymphoma has increased in the HAART era (log-rank chi-square, 9.23; P = 0.002). Univariate analyses using the established International Prognostic Index factors of age, tumor stage, lactate dehydrogenase level, Eastern Cooperative Oncology Group performance status, and number of extranodal sites were confirmed to be significant variables. Regression modeling for patients in whom disease was diagnosed after 1996 revealed only 2 independent predictors of death: International Prognostic Index risk group and CD4 cell count. These predictors yielded 4 internally validated risk strata with predicted 1-year survival rates of 82%, 47%, 20%, and 15% (P < 0.001). Prognostic risk scores in the highest quartile yielded a likelihood ratio for death of 7.90 (hazard ratio, 1.0), whereas a prognostic score less than 1.0 yielded a likelihood ratio of 0.23 (hazard ratio, 0.15 [95% CI, 0.06 to 0.33]). LIMITATIONS: The sample was small, and different HAART regimens were used. CONCLUSIONS: For patients with AIDS-related non-Hodgkin lymphoma that was diagnosed in the era of HAART, application of the International Prognostic Index remains useful. The addition of CD4 cell count provides further independent prognostic information. Patients who present with AIDS-related non-Hodgkin lymphoma and a low CD4 cell count have a poor prognosis; this information can be used to guide therapeutic options.

Hepatitis C infection is not associated with systemic HIV-associated non-Hodgkin's lymphoma: a cohort study.
Immunosuppression induced by the human immunodeficiency virus (HIV) increases the risk of developing non-Hodgkin's lymphoma (NHL). As the hepatitis C virus (HCV) has been implicated in the development of B cell lymphomas, we compared the incidence of systemic NHL during HIV infection compared to HIV and HCV co-infection. Of 5,832 individuals studied during the era of highly active anti-retroviral therapy (HAART), 102 patients were diagnosed with systemic NHL. The incidence of systemic NHL was 6.9 of 10(4) patient years during HIV infection compared to 7.1 of 10(4) patient years during HIV alone (p = 0.9). In this immunocompromised patient population, there was no association between HCV infection and an increased risk of lymphoma.

Hepatitis C virus infection in HIV type 1-infected individuals does not accelerate a decrease in the CD4+ cell count but does increase the likelihood of AIDS-defining events.
Human immunodeficiency virus type 1 (HIV-1) appears to adversely affect hepatitis C, but whether hepatitis C virus (HCV) has a reciprocal effect on HIV-1 infection remains a point of controversy. In a multivariate analysis of a cohort of 5832 individuals, we found that individuals coinfected with HCV and HIV-1 (prevalence of coinfection, 5.8%) had a CD4+ cell count that decreased at a rate similar to that for individuals infected with HIV-1 alone. However, coinfection was associated with a statistically significant increased likelihood of onset of an acquired immunodeficiency syndromedefining illness or developing a CD4+ cell count of <200 cells/mm3, compared with infection with HIV-1 alone (hazard ratio, 1.52; 95% confidence interval, 1.072.17). Patients who were naive to highly active antiretroviral therapy were significantly less likely to progress to either end point, because of their higher CD4+ cell counts. In conclusion, there was an increased number of adverse events in coinfected individuals, compared with individuals infected with HIV-1 alone.

Early virologic failure in HIV-1 infected subjects on didanosine/tenofovir/efavirenz: 12-week results from a randomized trial.
OBJECTIVE: To compare the safety and efficacy of two once-daily antiretroviral regimens containing lamivudine (3TC) or tenofovir disoproxil fumarate (TDF), each administered with didanosine (ddI) and efavirenz (EFV) as initial therapy to HIV-1-infected subjects. METHODS: Single centre, randomized (1: 1), open-label study in antiretroviral-naive, HIV-infected adults. Subjects commenced either 3TC/ddI/EFV (3TC group) or TDF/ddI/EFV (TDF group). Safety, Medication Event Monitoring System (MEMScap) and plasma EFV concentration monitoring was performed over the study period. Comparisons between groups were assessed using chi test and linear regression analysis was used to assess the relationship between EFV concentrations and virological response. RESULTS: Seventy-seven subjects were enrolled prior to recruitment being suspended, 36 to the 3TC group and 41 to the TDF group. Intention-to-treat analysis in which last observation carried forward (LOCF) found the mean viral log10 load [95% confidence interval (CI)] at weeks 4 and 12 to be 2.67 (2.47-2.87) and 1.83 (1.74-1.92) for the 3TC group and 2.75 (2.45-3.05) and 2.28 (1.96-2.6) for the TDF group (P = 0.013). Emergence of resistance occurred in five of 41 (12.2%) subjects in the TDF group up to week 12 compared with none of 36 in the 3TC group, (P < 0.05); these five subjects shared similar baseline characteristics (CD4+ cell counts < 200 x 10 cells/l and HIV-1 RNA > 100,000 copies/ml). Despite MEMScap monitoring showing > 99% adherence in all subjects, among the five failures, three had low EFV concentrations. CONCLUSION: TDF/ddI/EFV as initial therapy appears to have diminished efficacy in subjects with CD4 < 200 x 10 cells/l and viral load > 100,000 copies/ml. Treatment failure with resistance was not attributable to baseline resistance, efavirenz exposure or poor adherence.

Human BDCA-1-positive blood dendritic cells differentiate into phenotypically distinct immature and mature populations in the absence of exogenous maturational stimuli: differentiation failure in HIV infection.
Current immunological opinion holds that myeloid dendritic cell (mDC) precursors migrate from the blood to the tissues, where they differentiate into immature dermal- and Langerhans-type dendritic cells (DC). Tissue DC require appropriate signals from pathogens or inflammatory cytokines to mature and migrate to secondary lymphoid tissue. We show that purified blood mDC cultured in vitro with GM-CSF and IL-4, but in the absence of added exogenous maturation stimuli, rapidly differentiate into two maturational and phenotypically distinct populations. The major population resembles immature dermal DC, being positive for CD11b, CD1a, and DC-specific ICAM-3-grabbing nonintegrin. They express moderate levels of MHC class II and low levels of costimulatory molecules. The second population is CD11b(-/low) and lacks CD1a and DC-specific ICAM-3-grabbing nonintegrin but expresses high levels of MHC class II and costimulatory molecules. Expression of CCR7 on the CD11b(-/low) population and absence on the CD11b(+) cells further supports the view that these cells are mature and immature, respectively. Differentiation into mature and immature populations was not blocked by polymyxin B, an inhibitor of LPS. Neither population labeled for Langerin, E-cadherin, or CCR6 molecules expressed by Langerhans cells. Stimulation of 48-h cultured DC with LPS, CD40L, or poly(I:C) caused little increase in MHC or costimulatory molecule expression in the CD11b(-/low) DC but caused up-regulated expression in the CD11b(+) cells. In HIV-infected individuals, there was a marked decrease in the viability of cultured blood mDC, a failure to differentiate into the two populations described for normal donors, and an impaired ability to stimulate T cell proliferation.

Adherence to trizivir and tenofovir as a simplified salvage regimen is associated with suppression of viraemia and a decreased cholesterol.
BACKGROUND: Treatment failure during highly active antiretroviral therapy (HAART) is ultimately common and associated with the development of resistance mutations. Trizivir (zidovudine/lamivudine/abacavir) and tenofovir disoproxil fumarate may improve adherence and enhance virological suppression in individuals who have failed previous regimens. METHODS: Individuals were identified who had failed previous HAART and who were then prescribed trizivir and tenofovir. Viral load and genotypic information were obtained to assess virological response. RESULTS: One hundred and twenty-two individuals were identified from a database containing 5883 patients. In a last observation carried forward intention to treat analysis, 34% of individuals achieved an undetectable viral load of <50 copies/mL at 1 year. Of those who were able to remain on treatment for 1 year, 65% achieved undetectability. We observed no effect regarding previous regimens on viral outcome. Accumulation of TAMs (thymidine analogue mutations) was associated with a decrease in the number of patients achieving an undetectable viral load (with <2 TAMs present 38% of patients developed undetectable viral loads, > or =1;2 TAMs 17% undetectable; P = 0.03). Using the mean cell volume as a measure of compliance, those with higher values were more likely to achieve a viral load <50 copies/mL (P = 0.04). A beneficial effect on cholesterol was noted regardless of virological outcome. CONCLUSIONS: In compliant heavily pre-treated individuals with less than 2 TAMs, salvage therapy with trizivir and tenofovir is associated with suppression of viraemia and an improved lipid profile.

Conservation of unique cell-surface CD antigen mosaics in HIV-1-infected individuals.
Cluster of differentiation (CD) antigens are expressed on cells of myeloid and lymphoid lineages. As most disease processes involve immune system activation or suppression, these antigens offer unique opportunities for monitoring host responses. Immunophenotyping using limited numbers of CD antigens enables differentiation states of immune system cells to be determined. Extended phenotyping involving parallel measurement of multiple CD antigens may help identify expression pattern signatures associated with specific disease states. To explore this possibility we have made a CD monoclonal antibody array and scanner, enabling the parallel immunophenotyping of leukocyte cell suspensions in a single and rapid analysis. To demonstrate this approach, we used the specific example of patients infected with human immunodeficiency virus type-1 (HIV-1). An invariant HIV-induced CD antigen signature has been defined that is both robust and independent of clinical outcome, composed of a unique profile of CD antigen expression levels that are both increased and decreased relative to internal controls. The results indicate that HIV-induced changes in CD antigen expression are disease specific and independent of outcome. Their invariant nature indicates an irreversible component to retroviral infection and suggests the utility of CD antigen expression patterns in other disease settings.

Long term probability of detection of HIV-1 drug resistance after starting antiretroviral therapy in routine clinical practice.
BACKGROUND: Little is known about the long term risk of development of HIV-1 drug resistance for patients starting antiretroviral therapy (ART) with three or four drug regimens in routine clinical practice. METHODS: We analysed a large cohort study of patients seen in one of six large HIV clinics in and around London, UK. The focus of this analysis was on patients who started ART with two nucleosides plus either a single protease inhibitor (PI), a PI with ritonavir, abacavir or a non-nucleoside reverse transcriptase inhibitor (NNRTI). RESULTS: 4306 patients were followed; 1436 (33%) started with a single PI, 279 (6%) with a PI plus ritonavir, 156 (4%) with triple nucleosides and 2435 (57%) with an NNRTI. The overall cumulative risk of viral load failure was 38% by 6 years. Risk of > or =1 major IAS-USA mutation was 27% by 6 years; risk of mutations from at least two of the three main drug classes was 20% over the same period. These are lower limit estimates as test results were not available for many with viral load failure. Risk of PI mutations being detected in people who started ART with regimens containing a PI with ritonavir was significantly lower than the risk of NNRTI mutations being detected in those starting with NNRTI-containing regimens (relative hazard 0.3195% CI 0.15-0.61; p = 0.0008). CONCLUSION: In routine practice, rates of viral load failure and of resistance detection in patients who started ART with three or four drugs are appreciable.

Treatment exhaustion of highly active antiretroviral therapy (HAART) among individuals infected with HIV in the United Kingdom: multicentre cohort study.
OBJECTIVES: To investigate whether there is evidence that an increasing proportion of HIV infected patients is starting to experience increases in viral load and decreases in CD4 cell count that are consistent with exhaustion of available treatment options. DESIGN: Multicentre cohort study. SETTING: Six large HIV treatment centres in southeast England. PARTICIPANTS: All individuals seen for care between 1 January 1996 and 31 December 2002. MAIN OUTCOME MEASURES: Exposure to individual antiretroviral drugs and drug classes, CD4 count, plasma HIV RNA burden. RESULTS: Information is available on 16,593 individuals (13,378 (80.6%) male patients, 10,340 (62.3%) infected via homosexual or bisexual sex, 4426 (26.7%) infected via heterosexual sex, median age 34 years). Overall, 10,207 of the 16,593 patients (61.5%) have been exposed to any antiretroviral therapy. This proportion increased from 41.2% of patients under follow up at the end of 1996 to 71.3% of those under follow up in 2002. The median CD4 count and HIV RNA burden of patients under follow up in each year changed from 270 cells/mm3 and 4.34 log10 copies/ml in 1996 to 408 cells/mm3 and 1.89 log10 copies/ml, respectively, in 2002. By 2002, 3060 (38%) of patients who had ever been treated with antiretroviral therapy had experienced all three main classes. Of these, around one quarter had evidence of "viral load failure" with all these three classes. Patients with three class failure were more likely to have an HIV RNA burden > 2.7 log10 copies/ml and a CD4 count < 200 cells/mm3. CONCLUSIONS: The proportion of individuals with HIV infection in the United Kingdom who have been treated has increased gradually over time. A substantial proportion of these patients seem to be in danger of exhausting their options for antiretroviral treatment. New drugs with low toxicity, which are not associated with cross resistance to existing drugs, are urgently needed for such patients.

Boosted saquinavir hard gel formulation exposure in HIV-infected subjects: ritonavir 100 mg once daily versus twice daily.
OBJECTIVES: The amount of ritonavir needed to enhance saquinavir hard gel (hg) plasma concentrations is unclear. Reduced ritonavir dosing may help to reduce ritonavir-related side effects and costs. This study examined the pharmacokinetics of twice-daily saquinavir-hg (1000 mg) in the presence of ritonavir 100 mg, dosed twice-daily and once-daily on one single occasion. METHODS: Eighteen HIV-infected adults taking saquinavir/ritonavir 1000/100 mg twice-daily underwent pharmacokinetic (PK) assessment of saquinavir/ritonavir on day 1 following a morning saquinavir/ritonavir dose. On day 2, PK assessment was repeated when subjects took saquinavir without ritonavir. Drug intake (with a standard meal containing 20 g of fat) was timed on days -1, 1 and 2. Geometric mean ratios (GMR) and 95% confidence intervals (CI) were calculated to assess changes in saquinavir PK parameters. RESULTS: Geometric mean saquinavir AUC(0-12), C(trough), C(max) and elimination half-life on days 1 and 2 were 14 389 and 9590 ng.h/mL, 331 and 234 ng/mL, 2503 and 1893 ng/mL and 2.80 and 2.82 h, respectively. The GMR (95% CI) for these parameters were 0.67 (0.53-0.84), 0.71 (0.48-1.04), 0.76 (0.58-0.98) and 1.01 (0.86-1.18), respectively. CONCLUSIONS: Withholding a ritonavir dose significantly reduces overall saquinavir exposure and C(max), but had no impact on the elimination half-life. These data establish the need to administer saquinavir and ritonavir simultaneously.

Pharmacokinetics of saquinavir hard gel/ritonavir (1000/100 mg twice daily) when administered with tenofovir diproxil fumarate in HIV-1-infected subjects.
AIMS: To investigate whether the administration of tenofovir diproxil fumarate 300 mg once daily alters the plasma pharmacokinetics of the saquinavir hard gel/ritonavir combination in HIV-1 infected individuals. METHODS: On day 1, 12 h pharmacokinetic profiles for saquinavir/ritonavir (1000/100 mg given twice daily) were obtained for 18 subjects. All subjects were receiving ongoing treatment with a saquinavir/ritonavir-containing regimen. Tenofovir diproxil fumarate 300 mg given once daily was then added to the regimen and blood sampling was repeated at days 3 and 14. Saquinavir and ritonavir concentrations were measured by HPLC-MS/MS, and tenofovir concentrations by HPLC with UV detection. RESULTS: Following the addition of tenofovir diproxil fumarate to the regimen, saquinavir and ritonavir plasma concentrations were not significantly different compared with day 1. Thus the geometric mean ratios (95% confidence intervals) for the area under the concentration-time curve were 1.16 (0.97, 1.59) and 0.99 (0.87, 1.30) for saquinavir and 1.05 (0.92, 1.28) and 1.08 (0.97, 1.30) for ritonavir, on days 3 and 14, respectively. CONCLUSIONS: Tenofovir diproxil fumarate did not alter the pharmacokinetics of saquinavir hard gel/ritonavir.

A randomized trial to evaluate lopinavir/ritonavir versus saquinavir/ritonavir in HIV-1-infected patients: the MaxCmin2 trial.
OBJECTIVE: To assess the rate of protocol-defined treatment failure and safety of lopinavir/ritonavir (LPV/r) and saquinavir/ritonavir (SAQ/r). DESIGN: Open-label, prospective, randomized (1:1), international multi-centre trial. METHODS: Adult HIV-1-infected patients were assigned LPV/r 400/100 mg twice daily or SAQ/r 1000/100 mg twice daily with two or more nucleoside reverse transcriptase inhibitors (NRTIs)/non-NRTIs. All patients, whether on or off the assigned treatment, were followed for 48 weeks. RESULTS: Of 339 randomized patients, 324 initiated assigned treatment (intention-to-treat/exposed [ITT/e] population). At 48 weeks, treatment failure occurred in 29/163 (18%) and 53/161 (33%) of patients in the LPV/r and SAQ/r arms, respectively (ITT/e, P = 0.002, log rank test). In an analysis that also considered those patients who discontinued treatment as having failed treatment (ITT/e/discontinuation = failure), 40/161 (25%) LPV/r-treated individuals versus 63/161 (39%) SAQ/R-treated individuals failed treatment (P = 0.005, log rank test). Discontinuation of the assigned treatment occurred in 23/163 (14%) patients in the LPV/r-treated group, compared with 48/161 (300%) in the SAQ/r-treated group (ITT/e; P = 0.001). The primary reasons for premature discontinuation were non-fatal adverse events (LPV/r: 12/163; SAQ/r: 21/161) and patients' choice (LPV/r: 7/163; SAQ/r: 8/161). In the on-treatment analysis of time to treatment failure, no difference was observed between the two arms (P = 0.27, log rank test). CONCLUSION: LPV/r had better antiretroviral effects compared with SAQ/r at the doses and in the formulations studied. This may have been a result of patients' preferences and ability to adhere to assigned therapy, rather than a result of differences in the intrinsic potency of the study protease inhibitors.

A randomized study comparing a three- and four-drug HAART regimen in first-line therapy (QUAD study).
BACKGROUND: Evidence from randomized controlled trials supports the use of triple therapy. Research is required on the effectiveness of quadruple therapy in comparison to this and the relative effectiveness of specific highly active antiretroviral therapy (HAART) combinations. METHODS: Antiretroviral-naive individuals (n = 53) with an HIV-1 viral load >100 000 copies/mL were randomized to receive three-drug HAART with zidovudine/lamivudine (Combivir) and efavirenz or quadruple therapy with zidovudine/lamivudine/abacavir (Trizivir) and efavirenz (quad regimen). Patients continued on HAART for 48 weeks with regular clinical and immunological assessment. Standard and ultrasensitive (<5 copies/mL) viral load testing was carried out. RESULTS: A DAVG (difference in averages) analysis of the fall in viral load and increase in CD4 count showed no significant differences between regimens. Triple therapy resulted in a -4.17 log change (95% CI, -4.48 to -3.85) and quadruple therapy in a -4.36 log change (95% CI, -4.68 to -4.03) in viral load. For CD4 counts, the triple therapy arm increased by 164 cells/mm(3) (95% CI 112-217) and the quadruple arm by 185 (95% CI, 133-237). In an intent-to-treat analysis, 77% of patients in the triple therapy group reached an undetectable viral load (<50 copies/mL) compared with 84.2% of the quadruple therapy group. For ultrasensitive viral load testing, 23% and 18% of each group, respectively, reached undetectable viral loads. The hazard ratio for attaining a viral load of <5 copies/mL was 0.59 (95% CI, 0.26-1.33) for quadruple versus triple therapy. Three individuals in the triple therapy arm and nine in the quadruple therapy arm discontinued treatment. CONCLUSIONS: No differences in any analyses were observed between a standard of care regimen (zidovudine/lamivudine and efavirenz) and the quad regimen (zidovudine/lamivudine/abacavir and efavirenz).

HIV-associated anal cancer: has highly active antiretroviral therapy reduced the incidence or improved the outcome?
BACKGROUND: Highly active antiretroviral therapy (HAART) has reduced the incidence and improved the survival of patients with Kaposi sarcoma and AIDS-related non-Hodgkin lymphoma. We wished to evaluate its effects on incidence and survival in HIV-associated anal cancer. METHODS: We measured the incidence and survival of patients with invasive anal cancer from our prospective cohort of 8640 HIV-seropositive individuals. RESULTS: In our cohort of 8640 HIV-seropositive individuals, the incidence of invasive anal cancer (diagnosed in 26 patients) is 60 per 100,000 patient-years. This is 120 times higher than in the age- and gender-matched general population. The incidence of invasive anal cancer in the HIV cohort was 35 (95% confidence interval CI: 15-72) per 100,000 patient-years of follow-up in the pre-HAARTera (1984-1995) and 92 (95% CI: 52-149) per 100,000 patient-years of follow-up in the post-HAARTera (1996-2003) (P > 0.05). These figures are significantly higher than those for the general population (P < 0.001 for both) and give a relative risk of 67 and 176 in the pre- and post-HAART eras, respectively, compared with the general population. The 5-year overall survival is 47% (95% CI: 24%-70%), and the 5-year disease-free survival is 66% (95% CI: 45%-87%). There is no difference in overall survival between the pre- and post-HAART eras (log rank P = 0.19). CONCLUSIONS: Unlike other HIV-associated cancers, there has been no significant change in the incidence, clinical features, or overall survival since the introduction of HAART.
