RESUMO

BACKGROUND: Vaccines can be less immunogenic in people living with HIV (PLWH), but for SARS-CoV-2 vaccinations this is unknown. In this study we set out to investigate, for the vaccines currently approved in the Netherlands, the immunogenicity and reactogenicity of SARS-CoV-2 vaccinations in PLWH. METHODS AND FINDINGS: We conducted a prospective cohort study to examine the immunogenicity of BNT162b2, mRNA-1273, ChAdOx1-S, and Ad26.COV2.S vaccines in adult PLWH without prior COVID-19, and compared to HIV-negative controls. The primary endpoint was the anti-spike SARS-CoV-2 IgG response after mRNA vaccination. Secondary endpoints included the serological response after vector vaccination, anti-SARS-CoV-2 T-cell response, and reactogenicity. Between 14 February and 7 September 2021, 1,154 PLWH (median age 53 [IQR 44-60] years, 85.5% male) and 440 controls (median age 43 [IQR 33-53] years, 28.6% male) were included in the final analysis. Of the PLWH, 884 received BNT162b2, 100 received mRNA-1273, 150 received ChAdOx1-S, and 20 received Ad26.COV2.S. In the group of PLWH, 99% were on antiretroviral therapy, 97.7% were virally suppressed, and the median CD4+ T-cell count was 710 cells/µL (IQR 520-913). Of the controls, 247 received mRNA-1273, 94 received BNT162b2, 26 received ChAdOx1-S, and 73 received Ad26.COV2.S. After mRNA vaccination, geometric mean antibody concentration was 1,418 BAU/mL in PLWH (95% CI 1322-1523), and after adjustment for age, sex, and vaccine type, HIV status remained associated with a decreased response (0.607, 95% CI 0.508-0.725, p < 0.001). All controls receiving an mRNA vaccine had an adequate response, defined as >300 BAU/mL, whilst in PLWH this response rate was 93.6%. In PLWH vaccinated with mRNA-based vaccines, higher antibody responses were predicted by CD4+ T-cell count 250-500 cells/µL (2.845, 95% CI 1.876-4.314, p < 0.001) or >500 cells/µL (2.936, 95% CI 1.961-4.394, p < 0.001), whilst a viral load > 50 copies/mL was associated with a reduced response (0.454, 95% CI 0.286-0.720, p = 0.001). Increased IFN-γ, CD4+ T-cell, and CD8+ T-cell responses were observed after stimulation with SARS-CoV-2 spike peptides in ELISpot and activation-induced marker assays, comparable to controls. Reactogenicity was generally mild, without vaccine-related serious adverse events. Due to the control of vaccine provision by the Dutch National Institute for Public Health and the Environment, there were some differences between vaccine groups in the age, sex, and CD4+ T-cell counts of recipients. CONCLUSIONS: After vaccination with BNT162b2 or mRNA-1273, anti-spike SARS-CoV-2 antibody levels were reduced in PLWH compared to HIV-negative controls. To reach and maintain the same serological responses as HIV-negative controls, additional vaccinations are probably required. TRIAL REGISTRATION: The trial was registered in the Netherlands Trial Register (NL9214). https://www.trialregister.nl/trial/9214.

RESUMO

During COVID-19 lockdown, the in-hospital number of HIV indicator conditions decreased disproportionally compared with other non-COVID-19 diseases, which was accompanied by reduced HIV testing rates, number and proportion of positive HIV tests, and new HIV referrals, with more late presentation after lockdown cessation, indicating a significantly impacted HIV care continuum.

RESUMO

BACKGROUND: Patients with HIV have a poor serological conversion rate with the standard vaccination strategy against hepatitis B virus (HBV) of around 50%. Vaccination with Fendrix confers much better results in these patients. In this study, we tested the effect of revaccination with Fendrix in prior nonresponding patients with HIV and aimed to determine which factors are associated with seroconversion. METHODS: Eight Dutch HIV treatment centers participated in this retrospective study. Patients infected with HIV-1 and nonresponding to prior course of vaccination against HBV (anti-HBs <10 IU/ml) and who had Fendrix as a second, third or fourth effort to achieve seroconversion were eligible for inclusion. Primary outcome was the proportion of patients with seroconversion after revaccination with Fendrix. Univariate binary logistic regression analyses were used to determine which factors could be used as predictors for seroconversions. RESULTS: We included 100 patients with HIV. The mean age was 47.3 (±11.0) years and 86% were men. Revaccination with Fendrix showed a seroconversion rate of 81% (95% confidence interval 72-88%). Median nadir CD4+ cell count was 300 (20-1040) cells/µl and median CD4+ cell count at the time at starting vaccination with Fendrix was 605 (210-1190) cells/µl. Regression analyses showed no significant factor associated with seroconversion. CONCLUSIONS: Revaccination with Fendrix of patients prior nonresponding to other hepatitis B vaccination strategies has a high success rate. Eighty-one percentage responded with seroconversion, irrespective of CD4+ cell count.

RESUMO

BACKGROUND & AIMS: HIV/hepatitis B virus (HBV) coinfected subjects are thought to have faster progression to end-stage liver disease (ESLD) than HBV mono-infected subjects. We assessed whether this remains in the current cART-era. METHODS: Data from subjects with follow-up completion post-2003 were compared between HIV/HBV coinfected subjects in the Dutch HIV Monitoring database and HBV mono-infected subjects from two centres. The primary outcomes of composite ESLD included portal hypertension, decompensated cirrhosis, hepatocellular carcinoma, liver transplantation and liver-related mortality. Outcomes were analysed using time-dependent cause-specific Cox regression models adjusted for follow-up time and relevant covariates. Subset-analyses were done in subjects with follow-up pre-2003. RESULTS: In the 1336 co- vs 742 mono-infected subjects, coinfected subjects had no increased probability for ESLD compared to mono-infected subjects (cHR 0.7 (95% CI 0.4-1.1), but had increased probabilities for all-cause (cHR 7.4 [4.9-11.1]) and liver-related mortality (cHR 3.4 [1.6-7.5]). In the current combined cohort, treatment with tenofovir or entecavir was inversely associated with ESLD, all-cause and liver-related mortality (cHR 0.4 [95% CI 0.3-0.7], cHR 0.003 [0.001-0.01]), cHR 0.007 [0.001-0.05]). Other predictors for ESLD were older age, being of Sub-Sahara African descent, increased alanine aminotransferase levels and hepatitis C virus coinfection. While the probability for all-cause mortality was increased in coinfected subjects, this rate decreased compared to pre-2003 (HR 40.2 (95% CI: 8.7-186.2). CONCLUSIONS: HIV/HBV coinfected patients no longer seem to be at increased risk for progression to ESLD compared to HBV mono-infected patients, likely due to widespread use of highly effective cART with dual HBV and HIV activity.

RESUMO

Staphylococcus aureus bacteraemia (SAB) is a common and severe disease. In 2012, a structured bedside consultation (SBC) was introduced at Rijnstate Hospital. We analysed the effect of this SBC on the overall survival of patients with SAB and the effect on the diagnostic workup. We performed a retrospective cohort study, including all patients over 18 years with SAB from 2009 until 2017. The cases preceding versus those after implementation of SBC in 2012 were compared. In total, 613 episodes of SAB were analysed: 234 cases before and 379 cases since SBC. In 484 patients at risk for a complicated course, there was no significant difference in the 30-day survival (77 versus 82%, p = 0.18); however, an increase in 365-day survival was seen (56 versus 64%, p = 0.05). Overall, more patients received adequate therapy, both in the first 2 weeks (67.8 versus 86.7%, p < 0.001), as in complicated SAB (70.5 versus 93.2%, p < 0.001). In 21% of patients with transoesophageal echocardiogram (TEE) following a negative or inconclusive TTE, endocarditis was diagnosed. In patients at risk for complicated SAB, the PET scan revealed a metastatic infection which was not clinically suspected in 65% of positive PET scans. Structured bedside consultation is associated with a better 365-day survival in patients at risk for complicated SAB. Moreover, the additional value of TEE and the PET scan was shown. We strongly advise compliance to SBC in all patients at risk for complicated SAB and the use of both TEE and PET scans in these patients. Even in uncomplicated SAB, TEE or PET scan can reveal metastatic infections.

RESUMO

BACKGROUND: Single-drug class regimens with nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) are generally not recommended as initial therapy because they are inferior compared with therapy with two NRTIs plus efavirenz. However, triple-NRTI combinations can be useful in specific circumstances such as in tuberculosis coinfection, pregnancy or dyslipidaemia. Here, we review the potential of such combinations to maintain viral suppression after induction of suppression by standard combination antiretroviral therapy (cART) and to evaluate the trade-off of NRTI-only regimens for metabolic control. METHODS: We conducted a systematic search of the literature in two databases from 1 January 1998 up to 1 March 2013: Medline, through the search engine PubMed, and Embase. RESULTS: A total of 11 randomized controlled trials (RCTs) with 2,105 patients and 3 observational studies with 2,639 patients were included. Studies including patients with mono- or dual-NRTI treatment before start of effective cART showed a tendency to higher failure rate because of resistance based on archived viral mutations. In studies with ART-naive subjects before start of cART, triple-NRTI combination showed virological activity comparable to two NRTIs plus a protease inhibitor or a non-nucleoside reverse transcriptase inhibitor in all RCTs, but not in one cohort study. Switching improved serum lipids significantly. CONCLUSIONS: Of the studied triple-NRTI combinations only abacavir/lamivudine/zidovudine was sufficiently potent. Triple-NRTI maintenance after successful induction with two-class cART appeared successful in treatment-naive subjects and remains a useful option in specific circumstances, especially when other drugs are not available or drug interactions are an issue.

RESUMO

Maintenance with a triple nucleoside reverse transcriptase Inhibitor (NRTI) regimen after successful induction with a dual NRTI/protease inhibitor (PI) combination may be advantageous, because of low pill burden, favorable lipids, and less drug interactions. This strategy to become free of PI-related problems without losing viral efficacy has not been formally tested. We performed a randomized, open-label, multicenter, 96-week comparative study in antiretroviral therapy (ART)-naïve patients with CD4 50 copies per milliliter). Two hundred seven patients had similar baseline (BL) characteristics: median CD4 180 cells/mm(3), median VL 5.19 log(10) copies per milliliter. One hundred twenty subjects (58%) met randomization criteria. Baseline VL differed significantly between dropouts and randomized subjects (median 5.41 versus 5.06 log(10) copies per milliliter, p = 0.017), as did CD4 cells (median 160 and 200 cells/mm(3), p = 0.044). Sixty-one subjects received TZV and 59 subjects continued NRTIs/PI. At week 48, 2 patients in the TZV group and 5 in the PI group did not have a sustained virologic suppression (log rank test; p = 0.379). CD4 counts increased significantly in both arms. In ART-naïve patients, TZV maintenance had similar antiviral efficacy compared to continued standard ART at 48 weeks after baseline. Patients on successful standard ART can be safely switched to a NRTI-only regimen, at least for the tested time period.
