[PMID: 38699478 PMCID: PMC11064646 DOI: 10.3389/fmicb.2024.1376141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Accepted: 04/01/2024] [Indexed: 05/05/2024] Open
Abstract
Objective This study aimed to evaluate the prevalence of human papillomavirus (HPV) infection and presence of licensed HPV vaccine genotypes among patients with genital warts in Foshan, China from 2015 to 2022, to provide useful references for the detection, prevention and control of genital warts in Foshan. Methods The present study retrospectively analyzed the HPV detection rates in patients with genital warts. A total of 1,625 patients were seen at the Second People's Hospital of Foshan, Guangdong Province, China, from 2015 to 2022. Samples were collected from various lesions and genotyped for 21 genotypes of HPV by infusion hybridization. The classification principle of HPV genotypes in this study: (1) Based on the relationship between HPV and carcinogenicity; (2) Based on the number of HPV genotypes infected; (3) Based on the HPV genotypes of licensed HPV vaccines. Results The detection rate of any HPV in patients with genital warts was 80.37% (1,306/1,625). The detection rates of HPV for low-risk infection, co-infection and high-risk infection were 49.48% (804/1,625), 24.92% (405/1,625) and 5.97% (97/1,625), respectively. Single infection was the predominant type (51.94%, 844/1625). HPV-6 and HPV-11 were the predominant types of single infection; HPV-6 and HPV-52 were the predominant types of paired combinations of multiple infection. 82.22% (1,336/1,625) of the cases had an age distribution of ≤ 24, 25-34, and 35-44. The distribution of some HPV genotypes had age specificity, annual specificity and gender specificity. The genotype detection rates of 2v, 4v and 9v showed a decreasing trend with ages (all P < 0.05). The genotype detection rates of 4v and 9v showed a decreasing trend over the 8-year period (both P < 0.05). The genotype detection rates of 4v and 9v in the male group were higher than those in the female group (both P < 0.05). The genotype detection rate of 9v was significantly higher than that of 2v and 4v in the female group (both P < 0.05). Conclusion Our study demonstrated that low-risk infection and single infection were the main types of HPV infection in patients with genital warts, mainly among young patients. Our study provides epidemiological data for the detection, prevention and control of genital warts in China.

Experimental pneumococcal carriage in people living with HIV in Malawi: the first controlled human infection model in a key at-risk population. Wellcome Open Res 2024; 9:2.

Abstract
Background: As well as suffering a high burden of pneumococcal disease people living with HIV (PLHIV) may contribute to community transmission in sub-Saharan African (sSA) settings. Pneumococcal vaccination is not currently offered to PLHIV in sSA but may prevent disease and reduce transmission. More evidence of vaccine effectiveness against carriage in PLHIV is needed. An Experimental Human Pneumococcal Carriage model (EHPC) has been safely and acceptably used in healthy adults in Malawi to evaluate pneumococcal vaccines against carriage and to identify immune correlates of protection from carriage. This study will establish the same model in PLHIV and will be the first controlled human infection model (CHIM) in this key population. Methods: Healthy participants with and without HIV will be inoculated intranasally with Streptococcus pneumoniae serotype 6B. Sequential cohorts will be challenged with increasing doses to determine the optimal safe challenge dose to establish experimental carriage. Nasal fluid, nasal mucosal, and blood samples will be taken before inoculation and on days 2, 7, 14, and 21 following inoculation to measure pneumococcal carriage density and identify immune correlates of protection from carriage. The vast majority of natural pneumococcal carriage events in PLHIV do not result in invasive disease and no invasive disease is expected in this study. However, robust participant safety monitoring is designed to identify signs of invasive disease early should they develop, and to implement treatment immediately. Participants will complete a Likert-style questionnaire at study-end to establish acceptability. Interpretations: We expect the EHPC model to be safely and acceptably implemented in PLHIV. The CHIM can then be used to accelerate pneumococcal vaccine evaluations in this population, and an evidence-based pneumococcal vaccination policy for PLHIV in sSA.

Hibbert M, Simmons R, Ratna N, Mandal S, Sabin C, Desai M, Mohammed H. Retrospective cohort study assessing coverage, uptake and associations with hepatitis B vaccination among females who engage in sex work attending sexual health services in England between 2015 and 2019. Sex Transm Infect 2023; 99:497-501. [PMID: 37550014 DOI: 10.1136/sextrans-2023-055845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Accepted: 07/15/2023] [Indexed: 08/09/2023] Open
Abstract
OBJECTIVES Females who engage in sex work (FSW) are at high risk of hepatitis B virus (HBV) and are eligible for HBV vaccination. The objective of this analysis was to explore coverage, uptake and correlates of HBV vaccination among FSW who attend sexual health services (SHS) in England. METHODS Data on all attendances at SHS in England were obtained from the GUMCAD STI Surveillance System. Attendees were eligible for inclusion if they were female, had not been previously diagnosed with HIV and sex work was recorded between 2015 and 2019. Bivariable and multivariable logistic regression models were used to investigate sociodemographic factors (age, ethnicity, region of birth and region of residence) associated with having received an HBV vaccination on or after an attendance where sex work was reported. RESULTS There were 13 769 FSW attending SHS in England between 2015 and 2019 (median age 30 years, 71% white ethnicity). HBV vaccination coverage was 37% (n=5050/13 751, 95% CI 35.9%-37.5%). Among those that first reported sex work between 2015 and 2019, HBV vaccination uptake was 30% (n=3249/10 681, 95% CI 29.6%-31.3%). In multivariable analyses, HBV vaccination uptake was associated with younger age (5-year increase: OR=0.87, 95% CI 0.85, 0.89) and being born in South America (37%, adjusted OR (aOR)=1.40, 95% CI 1.18, 1.66) compared with being born in the UK. Being of Asian ethnicity (19%, aOR=0.63, 95% CI 0.45, 0.89) compared with white ethnicity was associated with reduced odds of HBV vaccination. Sixteen FSW were diagnosed with HBV after their first attendance where sex work was recorded. CONCLUSIONS To achieve the WHO goals of elimination of HBV as a public health threat by the year 2030, further research is needed to understand the individual and structural barriers to the offering and uptake of HBV vaccination among FSW, as well as using health promotion methods to improve uptake.

Impact of frequency and duration of freeze-dried inactivated tissue culture hepatitis A vaccine (Aimmugen®) vaccination on antibody titers; a japanese cross-sectional study. Vaccine 2023; 41:5974-5978. [PMID: 37620202 DOI: 10.1016/j.vaccine.2023.08.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 07/26/2023] [Accepted: 08/14/2023] [Indexed: 08/26/2023]
Abstract
BACKGROUND The effect of the timing of additional doses and the long-term persistence of lyophilized inactivated tissue culture hepatitis A (HA) vaccine (Aimmugen®) on antibodies is unknown. METHODS A single-center, cross-sectional, observational study was conducted in collaboration with the Japan Air Self-Defense Force, whose personnel were immunized with Aimmugen® when deployed to endemic areas. Patients who consented to this study after a medical examination with blood sampling between June 2022 and February 2023 were included; HA-IgG level in the residual serum was measured using the chemiluminescent immunoassay method. The exact vaccination history was investigated based on immunization records maintained by the Ministry of Defense, and a questionnaire was used to collect confounding factors. RESULTS Of the 181 participants observed, 49 were in the unvaccinated group, and 132 were in the vaccinated group. Out of the vaccinated group, 6.8 % received either one or two doses, 40.9 % received three doses, and 52.3 % received more than four doses. IgG antibody titers (S/CO value) in each group (0, 1 or 2, 3, and over 4) increased in a frequency-dependent manner, with those vaccinated over four times showing significantly higher IgG antibody titers than all other groups (0.19 ± 0.10 vs 3.66 ± 3.00 vs 7.63 ± 3.57 vs 10.57 ± 1.86, respectively). When the number of months elapsed from the last vaccination to the date of blood collection in each group was plotted against IgG antibody titer, the slope of the regression line flattened out from a decreasing trend in the order 1 or 2, 3, over 4. CONCLUSIONS Three doses of Aimmugen® are efficacious, but four or more doses induce more robust and sustained antibody production. Additionally, four or more doses may be effective when there is a need to ensure long-term immunity or risk of prolonged exposure.

The propositive study: Immunogenicity and safety of a four-component recombinant protein-based vaccine against MenB and a quadrivalent conjugate MenACWY vaccine in people living with HIV. HIV Med 2023; 24:979-989.

Abstract
BACKGROUND People living with HIV have been shown to have an increased risk of invasive meningococcal disease. In some countries, meningococcal vaccines are now routinely recommended to all people living with HIV, but no study has yet assessed the immunogenicity and safety of a meningococcal serogroup B vaccine or the co-administration of a MenB and MenACWY vaccine in people living with HIV. METHODS This phase IV open-label clinical trial investigated the immunogenicity and safety of two doses of a four-component recombinant protein-based MenB vaccine (4CMenB) and a quadrivalent conjugate polysaccharide MenACWY vaccine (MenACWY-CRM197) given 1 month apart in a population of people living with HIV. Immunogenicity analysis was performed before vaccination and 1 month after the second doses of 4CMenB and MenACWY. Primary outcome measures were serum bactericidal assay geometric mean titres against three MenB reference strains at baseline and 1 month post vaccination, the proportion of participants achieving a putative protective titre of ≥4, and the proportion of participants with a ≥4-fold rise in titre from baseline. Secondary outcome measures were serum bactericidal assay geometric mean titres against MenA, C, W, and Y reference strains at baseline and 1 month post vaccination, the proportion achieving a putative protective titre of ≥8, and the proportion with a ≥4-fold rise in titre from baseline. Safety outcomes were solicited and unsolicited adverse events in the 7 days following vaccination. The trial was registered with clinicaltrials.gov (NCT03682939). FINDINGS In total, 55 participants aged 20-45 years were enrolled. All participants (100%; 95% confidence interval [CI] 93-100) achieved putative protective titres for two of the three MenB strains and for MenA, W, and Y. A total of 98% (95% CI 89-100) achieved a protective titre for the third MenB strain and 94% (95% CI 83-99) for MenC. No serious adverse events were reported. INTERPRETATION 4CMenB and MenACWY were immunogenic and well-tolerated in a population of people living with HIV 1 month after two doses.

Abstract
After 40 years of its appearance, human immunodeficiency virus (HIV) infection remains a leading public health challenge worldwide. Since the introduction of antiretroviral treatment (ART), HIV infection has become a chronic condition, and people living with HIV could have life expectancies close to those of the general population. People with HIV often have an increased risk of infection or experience more severe morbidity following exposure to vaccine-preventable diseases. Nowadays, several vaccines are available against bacteria and viruses. However, national and international vaccination guidelines for people with HIV are heterogeneous, and not every vaccine is included. For these reasons, we aimed to perform a narrative review about the vaccinations available for adults living with HIV, reporting the most updated studies performed for each vaccine among this population. We performed a comprehensive literature search through electronic databases (Pubmed-MEDLINE and Embase) and search engines (Google Scholar). We included English peer-reviewed publications (articles and reviews) on HIV and vaccination. Despite widespread use and guideline recommendations, few vaccine trials have been conducted in people with HIV. In addition, not all vaccines are recommended for people with HIV, especially for those with low CD4 cells count. Clinicians should carefully collect the history of vaccinations and patients' acceptance and preferences and regularly check the presence of antibodies for vaccine-preventable pathogens.

Recommendations for defining preventable HIV-related mortality for public health monitoring in the era of Getting to Zero: an expert consensus. Lancet HIV 2023; 10:e195-e201.

Abstract
Getting to Zero is a commonly cited strategic aim to reduce mortality due to both HIV and avoidable deaths among people with HIV. However, no clear definitions are attached to these aims with regard to what constitutes HIV-related or preventable mortality, and their ambition is limited. This Position Paper presents consensus recommendations to define preventable HIV-related mortality for a pragmatic approach to public health monitoring by use of national HIV surveillance data. These recommendations were informed by a comprehensive literature review and agreed by 42 international experts, including clinicians, public health professionals, researchers, commissioners, and community representatives. By applying the recommendations to 2019 national HIV surveillance data from the UK, we show that 30% of deaths among people with HIV were HIV-related or possibly HIV-related, and at least 63% of these deaths were preventable or potentially preventable. The application of these recommendations by health authorities will ensure consistent monitoring of HIV elimination targets and allow for the identification of inequalities and areas for intervention.

Abstract
OBJECTIVES Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) are the two leading viruses that cause the greatest number of virus-related morbidities in the world. HIV/HBV coinfection is correlated with high morbidity and mortality. For this particular reason hepatitis B vaccination is crucial for people living with HIV. METHODS Patients who are being followed-up for HIV/AIDS and who have received a hepatitis B vaccine in 4 HIV clinics over a 5-year time period have been studied. Our multi-centered, retrospective, cross-sectional and observational study investigates factors that affect hepatitis B vaccination immune response of individuals living with HIV. The patients have been studied for the parameters such as age, sex, CD4 count at the time of diagnosis or vaccination, HIV-RNA levels, comorbidities, vaccine dosage, success of immunization after vaccination, and the demographics of the patients who have and have not developed immunity. RESULTS Of 645 patients that are being followed-up in our clinics, 158 received hepatitis B vaccine; 39 of these 158 patients have been excluded from the study because they did not fulfil the inclusion criteria. Finally, 119 patients were evaluated in the study, 17 of the patients (14.3%) were females and 102 (85.7%) were males. The median age was 41.11 ± 10.09 (min-max: 18-75). Twenty-three of the patients (19.3%) were at the stage of AIDS during diagnosis while 80.7% were at the stage of HIV infection. Ninety-one of the patients (76.5%) have been administered a single dose hepatitis B vaccine on the standard 0, 1st, 6th month vaccination schedule, whereas 23.5% were administered a double dose on the same vaccination schedule. When further evaluated to find whether the patient was able to develop sufficient immunity (anti-HBs ≥ 10), it was found that the immune response was statistically significantly higher in the patients whose CD4 count was greater than 200 at the time of the first diagnosis and vaccination (p = 0.05 and p = 0.001, respectively). The patients have also been evaluated according to the number of doses they received (1 vs. 2). The immune response of the patients who received two doses was statistically significantly higher (p = 0.041). CONCLUSION We can conclude that in the patients with CD4 count less than 200 at the time of their diagnosis and vaccination a high dose recombinant hepatitis B vaccine should definitely be administered as the normal dose and higher dose have similar side effect profiles and the higher dose provides greater immunity.

Abstract
The dissemination of the fact that the human papillomavirus (HPV) vaccine can protect females as well as males is greatly beneficial for the control of condyloma acuminata (CA). We aimed to investigate the acceptance of the HPV vaccine for CA among men who have sex with men (MSM) in China. A cross-sectional online survey in the adult MSM population from 31 regions in China was carried out via WeChat in May 2017. Information on demographic characteristics, sexual behaviors, history of HIV and HPV infection, awareness of CA and HPV/CA vaccines, acceptance of CA vaccination, and behavioral intentions for vaccination were collected through a self-administered questionnaire. In total, 902 questionnaires were analyzed; the prevalence of CA was 13.3% (120/902), the HIV positivity rate was 15.1% (136/902), and the coinfection rate of HIV and CA was 3.9% (35/902). In the MSM population, the knowledge of CA and HPV/CA vaccines was poor, but the acceptance rate of the CA vaccine was high (85.1%, 768/902). Data indicated that MSM who had a history of anal intercourse (OR = 1.9), had heard of CA (OR = 2.9), knew the treatments for CA (OR = 2.0), had heard of HPV vaccines/cervical cancer vaccines (OR = 1.9), and received education about CA (OR = 1.9) were associated with the intention to use CA vaccines. With current moderate levels of CA and HPV/CA vaccine awareness, more emphasis should be placed on improving education and other behavioral interventions for high-risk populations such as MSM in China.

Abstract
BACKGROUND HIV infection is associated with an increased risk of morbidity and mortality from vaccine preventable infections. This research describes, in the context of changing patient demographics, the seroprevalence of vaccine preventable viral infections among attendees of the largest centre for HIV positive patients in Ireland. METHODS Baseline serum IgG results for measles, mumps, rubella, varicella zoster virus (VZV) & hepatitis A, as well as hepatitis B sAg, cAb and sAb results, were retrieved for 2534 clinic attendees attending in 2018. Results were available for between 990 and 2363 attendees (39-93%), depending on the test, and were compared with 2013 clinic data. RESULTS There was a 35% increase in attendees in 2018 when compared to 2013. The largest increase was in attendees of South American origin. In 2018, males accounted for 73% of the entire cohort and the HIV acquisition risk for 48% of attendees was MSM. 47% of attendees were originally from Ireland. Among those tested, 33% were susceptible to at least one component of the MMR vaccine. 5% were VZV non-immune (significantly associated with younger age and the acquisition risk status of injection drug use). 21% were hepatitis A non-immune (significantly associated with younger age and being of European or South American origin). 32% were hepatitis B cAb seropositive (significantly associated with older age, injection drug use status and being originally from Africa). 3% demonstrated hepatitis B sAg positivity. 64% had hepatitis B sAb ≥ 10mIU. CONCLUSION In a cohort of attendees to an HIV clinic in a large urban setting, the susceptibility to several common vaccine preventable viral infections, in particular MMR and hepatitis A and B, was high. These results highlight the importance of proactive screening and immunisation to help protect this high risk patient group against vaccine preventable diseases.

Abstract
In March, people living with HIV infection (PLWH) were included in the risk category of fragile people for severe COVID-19 receiving priority access to vaccination with BNT162b2 vaccine. The aim of the study was to evaluate the immunogenicity and safety of the two doses regimen. The antibodies titer for severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) was evaluated after 21 days since the first administration (Time 1), 1 (Time 2), and 3 (Time 3) months post-vaccination. Information regarding virological and immunological conditions at baseline, previous SARS-CoV-2 state of infection, other immunodeficiencies, current antiretroviral therapy (ART), comorbidities, and severe adverse events (SAE) to vaccination was collected. Six hundred and ninety-seven patients were tested for quantitative anti-spike antibodies at Time 1, 577 patients had a second detection at Time 2, and 491 patients had the third detection. Baseline characteristics of the study population are reported in Table 1. At the time of vaccine administration, all patients were on ART (except one long-term nonprogressor); 632 (90.7%) patients had undetectable HIV-RNA; 12 (1.7%) patients were immunosuppressed due to chemotherapy or other immunosuppressive drugs; 345 (49.5%) patients had at least one COVID-19 related comorbidity and 155 (22.2%) had two or more comorbidities. No SAEs were reported. Final serological results are available for 694 patients after the first dose, 577 and 491 after the second and third ones, respectively; positive titer (values ≥ 50 AU/ml) was demonstrated in 653 (94.1%), 576 (99.8%), 484 (98.6%) patients, respectively. Only one patient was a nonresponder after completing vaccination, who was a newly diagnosed one for HIV infection. All vaccinations were well tolerated, with no SAEs. BNT162b2 mRNA vaccine was immunogenic and safe in PLWH.

Abstract
Human papillomavirus (HPV) and human immunodeficiency virus (HIV) infections are sexually transmitted. There are several HPV genotypes and clinical manifestations. Determining which genotypes circulate worldwide and/or in specific geographic areas can help with prevention programs and vaccine distribution. This systematic review aimed to investigate the most frequent anal and cervical HPV genotypes in women co-infected with HPV/HIV. The PubMed, Scientific Electronic Library Online, and Latin American and Caribbean Literature in Health Sciences databases were used to search for articles published between January 2015 and August 2021, and the included articles followed the defined selection criteria. Based on the 51 articles included, HPV16 was the most prevalent (41%) genotype, followed by HPV52 (17%) and HPV58 (14%). Based on the comparative analyses of the HIV-negative women with HPV and the HPV/HIV co-infected groups, HPV16 was frequent in both groups; HPV58, HPV31, and HPV52 were more frequent in the co-infected group; and HPV18 was more common in HIV-negative women with HPV. HPV/HIV co-infected women most frequently presented the HPV genotypes 16, 58, and 52, whereas HIV-negative women with HPV had a higher frequency of HPV16, HPV18, and HPV52 genotypes. The results indicate the importance of genotype surveillance as a strategy to improve preventive measures against HPV infection and its complications.

Abstract
AIM After the hepatitis A virus (HAV) outbreak among men who have sex with men (MSM) around 2018, the importance of HAV vaccination was emphasized, especially for MSM-living with human immunodeficiency virus (MSM-LWHIV). Aimmugen® is licensed and distributed exclusively in Japan. While administration of three doses is recommended, 85% of recipients in the general population were reported to acquire seroprotection after the second dose. In this study, we evaluated the efficacy of two or three vaccine doses along with predictors associated with the response to Aimmugen® in MSM-LWHIV. METHODS We retrospectively examined anti-HA-IgG titers of MSM-LWHIV vaccinated with Aimmugen® in our hospital. Patients' data were collected from medical records. RESULTS Between January 2018 and October 2019, 141 subjects whose median age was 46 years old, were examined. All the subjects were on antiretroviral therapy (ART) and the median CD4 count was 615/μL. The acquisition rate of protectable anti-HA-IgG titers after the second and third dose was 71.1% and 98.6%, respectively. In 114 subjects whose anti-HA-IgG titers were tested after the second-dose, factors significantly associated with better response were prolonged ART duration and higher CD4 count. The titers of anti-HA-IgG after the third dose were higher in those who became seropositive after the second-dose than those who did not. CONCLUSIONS Three-dose of Aimmugen® for MSM-LWHIV was effective while two-dose was less effective compared to non-HIV-infected people. People-LWHIV with shorter duration of ART and lesser CD4 cell count achieved lower titers of anti-HA-IgG and might require an additional vaccination.

Abstract
OBJECTIVES Estimate the durability of tetanus toxoid (TT) -specific seroprotection in a cohort of people living with HIV (PLWH). DESIGN Cross-sectional study. METHODS PLWH with a last date of TT booster available were identified. TT-specific IgG were detected using commercial ELISA kit. Durability of seroprotection was estimated using linear regression model and analyzed according to the country of birth. The impact of baseline parameters at the time of vaccination (CD4+ T cell count, viral load and ART) was also assessed. RESULTS One-hundred and three subjects were included. The median duration between last TT booster and sampling was 5.6 years (IQR 2.6-8.9). Using linear regression model, half-life of TT-specific antibody was estimated at 9.9 years (95% CI: 5.5-50) in the whole cohort. Half-life was reduced in subjects born outside Europe: 4.4 years (95% CI: 2.9-8.5). PLWH born outside Europe had lower CD4+ T cell count at the time of immunization and more frequently a CD4+ T cell count nadir<200 mm3 before vaccination. CONCLUSIONS PLWH born outside Europe have lower half-life of TT-specific antibody as compared to previous study performed in the general population. Possible causes include lower nadir or current CD4+ T cell count or under-immunization status in country of origin before migration. Longer interval of booster vaccination, as recommended in the general population, might not be appropriate in this subgroup of PLWH.

Abstract
Background There is conflicting evidence about whether a double dose of the hepatitis B virus (HBV) vaccine induces better immunity than the standard-dose vaccine for people living with HIV (PLWH). This study provides a meta-analysis that summarizes the efficacy of HBV vaccine regimens among HIV-infected patients, clarifying the role of particular factors such as dose and frequency of vaccination in vaccine responsiveness and highlighting the need for evidence-based practice to assess HBV vaccination among PLWH. Methods Randomized clinical trials (RCTs) and prospective studies reporting vaccination response rates among PLWH were found through a search of PubMed, Cochrane, and the Web of Science. The key outcome was vaccine response. A random-effects model was used to estimate the pooled response rate. Subgroup analysis was conducted to evaluate key factors and explore sources of heterogeneity. Possible biases were assessed using quality and publication bias assessment. Results Eligible studies included controlled trials that examined the effects of 17 interventional studies with 1,821 participants. Among PLWH who received the HBV vaccine, the pooled response rate of HBV vaccination was 71.5% (95% CI 64.0%-77.9%, p < 0.001). Compared with the standard dose (65.5%, 95% CI 53.1%-76.1%), the double dose (75.2%, 95% CI 66.2%-82.5%) was associated with a better response rate [Q(1) = 19.617, p < 0.001]. When stratified by schedule, the four-dose schedule (89.7%, 95% CI 83.1%-93.9%) had a higher response rate than the three-dose schedule (63.3%, 95% CI 56.6%-69.4%) and the difference was significant [Q(1) = 88.305, p < 0.001]. PLWH with higher CD4+ T-cell counts (>500 cells/mm3) at the time of vaccination had better response rates [Q(1) = 88.305, p < 0.001]. Conclusions In this meta-analysis, the double dose of the HBV vaccine and multiple injections were associated with better immune responses than the standard HBV vaccine regimen in PLWH. Higher seroconversion rates were observed in PLWH with high CD4+ T-cell levels, indicating that individuals infected with HIV should receive the HBV vaccine as soon as possible after diagnosis.

Abstract
BACKGROUND With initiation of antiretroviral therapy (ART) containing nucleos(t)ide reverse-transcriptase inhibitors (NRTIs) with anti-hepatitis B virus (HBV) activity, the evolution of HBV serologic markers among people living with HIV (PLWH) who were born in the era of nationwide neonatal HBV vaccination is rarely investigated. METHODS This retrospective cohort study evaluated the changes of HBV serologic markers (HBsAg, anti-HBs, and anti-HBc) of PLWH who had undergone neonatal HBV vaccination. Clinical characteristics were analyzed and the incidences of evolution of HBV serologic markers were estimated. RESULTS Between 2004 and 2020, 608 PLWH (mean age, 24 years) were included and 62.0% initiated tenofovir-containing ART: 13 (2.1%) were HBsAg-positive; 312 (51.3%) tested triple-negative; 209 (34.4%) had vaccine-induced seroprotection against HBV; and 74 (12.2%) tested positive for anti-HBc with or without anti-HBs. Among 492 PLWH who received a median follow-up of 2.8 years, 4 cases of incident HBV infection occurred (0.59 per 100 PYFU) in PLWH testing triple-negative at baseline despite ART containing NRTIs with anti-HBV activity. Of PLWH with seroprotection against HBV at baseline, 38 subsequently lost anti-HBs (4.46 per 100 PYFU) and 4 cases of incident HBV infection occurred (0.47 per 100 PYFU). PLWH with an anti-HBs antibody titer ≥100 mIU/ml at baseline (adjusted hazard ratio [aHR], 0.10; 95%CI, 0.02-0.42) and CD4 ≥500 cells/mm 3 during follow-up (aHR, 0.51; 95%CI, 0.30-1.00) were less likely to lose HBV seroprotection. CONCLUSIONS Among young PLWH who had undergone neonatal HBV vaccination, evolution of HBV serologic markers and incident infections occurred despite ART containing NRTIs with anti-HBV activity.

Abstract
BACKGROUND The comparative efficacy, and cost-effectiveness, of imiquimod or podophyllotoxin cream, either alone or in combination with the quadrivalent HPV vaccine (Gardasil®, Merck Sharp & Dohme Corp., Merck & Co., Inc., Whitehouse Station, NJ, USA) in the treatment and prevention of recurrence of anogenital warts is not known. OBJECTIVE The objective was to compare the efficacy of imiquimod and podophyllotoxin creams to treat anogenital warts and to assess whether or not the addition of quadrivalent human papillomavirus vaccine increases wart clearance or prevention of recurrence. DESIGN A randomised, controlled, multicentre, partially blinded factorial trial. Participants were randomised equally to four groups, combining either topical treatment with quadrivalent human papillomavirus vaccine or placebo. Randomisation was stratified by gender, a history of previous warts and human immunodeficiency virus status. There was an accompanying economic evaluation, conducted from the provider perspective over the trial duration. SETTING The setting was 22 sexual health clinics in England and Wales. PARTICIPANTS Participants were patients with a first or repeat episode of anogenital warts who had not been treated in the previous 3 months and had not previously received quadrivalent human papillomavirus vaccine. INTERVENTIONS Participants were randomised to 5% imiquimod cream (Aldara®; Meda Pharmaceuticals, Takeley, UK) for up to 16 weeks or 0.15% podophyllotoxin cream (Warticon®; GlaxoSmithKlein plc, Brentford, UK) for 4 weeks, which was extended to up to 16 weeks if warts persisted. Participants were simultaneously randomised to quadrivalent human papillomavirus vaccine (Gardasil) or saline control at 0, 8 and 24 weeks. Cryotherapy was permitted after week 4 at the discretion of the investigator. MAIN OUTCOME MEASURES The main outcome measures were a combined primary outcome of wart clearance at week 16 and remaining wart free at week 48. Efficacy analysis was by logistic regression with multiple imputation for missing follow-up values; economic evaluation considered the costs per quality-adjusted life-year. RESULTS A total of 503 participants were enrolled and attended at least one follow-up visit. The mean age was 31 years, 66% of participants were male (24% of males were men who have sex with men), 50% had a previous history of warts and 2% were living with human immunodeficiency virus. For the primary outcome, the adjusted odds ratio for imiquimod cream versus podophyllotoxin cream was 0.81 (95% confidence interval 0.54 to 1.23), and for quadrivalent human papillomavirus vaccine versus placebo, the adjusted odds ratio was 1.46 (95% confidence interval 0.97 to 2.20). For the components of the primary outcome, the adjusted odds ratio for wart free at week 16 for imiquimod versus podophyllotoxin was 0.77 (95% confidence interval 0.52 to 1.14) and for quadrivalent human papillomavirus vaccine versus placebo was 1.30 (95% confidence interval 0.89 to 1.91). The adjusted odds ratio for remaining wart free at 48 weeks (in those who were wart free at week 16) for imiquimod versus podophyllotoxin was 0.98 (95% confidence interval 0.54 to 1.78) and for quadrivalent human papillomavirus vaccine versus placebo was 1.39 (95% confidence interval 0.73 to 2.63). Podophyllotoxin plus quadrivalent human papillomavirus vaccine had inconclusive cost-effectiveness compared with podophyllotoxin alone. LIMITATIONS Hepatitis A vaccine as control was replaced by a saline placebo in a non-identical syringe, administered by someone outside the research team, for logistical reasons. Sample size was reduced from 1000 to 500 because of slow recruitment and other delays. CONCLUSIONS A benefit of the vaccine was not demonstrated in this trial. The odds of clearance at week 16 and remaining clear at week 48 were 46% higher with vaccine, and consistent effects were seen for both wart clearance and recurrence separately, but these differences were not statistically significant. Imiquimod and podophyllotoxin creams had similar efficacy for wart clearance, but with a wide confidence interval. The trial results do not support earlier evidence of a lower recurrence with use of imiquimod than with use of podophyllotoxin. Podophyllotoxin without quadrivalent human papillomavirus vaccine is the most cost-effective strategy at the current vaccine list price. A further larger trial is needed to definitively investigate the effect of the vaccine; studies of the immune response in vaccine recipients are needed to investigate the mechanism of action.

Abstract
PURPOSE OF REVIEW This review focuses on new evidence supporting the global immunization strategy for multiple sclerosis (MS) patients receiving disease-modifying drugs (DMDs), including the recently available vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. RECENT FINDINGS New data strengthen the evidence against a causal link between MS and vaccination. Recent consensus statements agree on the need to start vaccination early. Timings for vaccine administration should be adjusted to ensure safety and optimize vaccine responses, given the potential interference of DMDs. Patients treated with Ocrelizumab (and potentially other B-cell depleting therapies) are at risk of diminished immunogenicity to vaccines. This has relevant implications for the upcoming vaccination against SARS-CoV-2. SUMMARY An early assessment and immunization of MS patients allows optimizing vaccine responses and avoiding potential interference with treatment plans. Vaccinations are safe and effective but some specific considerations should be followed when vaccinating before, during, and after receiving immunotherapy. A time-window for vaccination taking into account the kinetics of B cell repopulation could potentially improve vaccine responses. Further understanding of SARS-CoV-2 vaccine response dynamics in MS patients under specific therapies will be key for defining the best vaccination strategy.

[PMID: 33715902 DOI: 10.1016/j.vaccine.2021.02.062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Revised: 01/14/2021] [Accepted: 02/24/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVES Tetanus is a vaccine-preventable disease. Booster immunization is required in order to induce long-lived tetanus-toxoid (TT) specific antibody response. We investigated the prevalence and risk factors of TT seronegativity in a cohort of people living with HIV (PWH) in Belgium along with the respective performance of vaccine history and a rapid dipstick test (Tetanus Quick Stick ® or TQS) compared to ELISA testing. METHODS PWH were prospectively enrolled and answered a questionnaire. ELISA was performed on serum or plasma using a commercial kit. A TT antibody level ≥ 0.15 IU / mL was considered protective. The TQS test was performed on a limited number of subjects. RESULTS Three-hundred forty-four subjects were included. The prevalence of tetanus seroprotection was 84,9%. Median age was 46.7 and 68% were born outside Belgium. Antiretroviral therapy coverage was almost universal (98.5%). After multivariable analysis, two risk factors were independently associated with TT seronegativity: an education level equivalent or below than secondary school and being born outside Europe. Vaccine history was shown to be unreliable (sensitivity: 43.8%; specificity: 76.5%; positive predictive value: 91.4% and negative predictive value :19.3%). The correlation between vaccine history and tetanus seroprotection was low (kappa coefficient = 0.09). The TQS performances were good (sensitivity 86.4%, specificity 96.0%, positive predictive value 99.3%, negative predictive value 52.17%). The correlation between TQS and tetanus seroprotection was substantial (kappa coefficient = 0.61). CONCLUSIONS In this cohort of PWH with a high proportion of migrants, socio-demographic and educational factors were associated with TT seronegativity while HIV-related factors were not, indicating that vaccine information should be tailored to cultural and educational background. As vaccine history is not reliable, TQS could represent an efficient tool for screening of TT-seronegativity.

Abstract
Introduction: The important development that the multiple sclerosis (MS) treatment field has experienced in the last years comes along with the need of dealing with new adverse events such as the increase risk of infections. In the shared therapeutic decision-making process, the MS expert neurologist should also balance the risks of specific infections under each particular treatment and be familiar with new mitigation strategies.Areas covered: In this review, the authors provide an up-to-date review of the infection risk associated with MS treatments with a specific focus on risk mitigating strategies. The search was conducted using Pubmed® database (2000 - present) to identify publications that reported infection rates and infection complications for each treatment (interferon beta, glatiramer acetate, teriflunomide, dimethyl fumarate, fingolimod, cladribine, natalizumab, alemtuzumab, rituximab, and ocrelizumab).Expert opinion: Since the emergence of the first natalizumab-related PML case, the arrival of new MS therapies has come hand in hand with new infectious complications. MS-specialist neurologist has to face new challenges regarding the management of immunosuppression-related infectious complications. The implementation of patient-centered management focus on preventive and mitigating strategies with a multidisciplinary approach should be seen in the future as a marker of excellence of MS management.

Immune response to the hepatitis B vaccine among HIV-infected adults in Uganda. Vaccine 2021; 39:1265-1271. [PMID: 33516601 DOI: 10.1016/j.vaccine.2021.01.043] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 11/09/2020] [Accepted: 01/16/2021] [Indexed: 01/01/2023]
Abstract
BACKGROUND Co-infection with hepatitis B virus (HBV) and human immunodeficiency virus (HIV) is common in sub-Saharan Africa (SSA) and can rapidly progress to cirrhosis and hepatocellular carcinoma. Recent data demonstrate ongoing HBV transmission among HIV-infected adults in SSA, suggesting that complications of HIV/HBV co-infection could be prevented with HBV vaccination. Because HBV vaccine efficacy is poorly understood among HIV-infected persons in SSA, we sought to characterize the humoral response to the HBV vaccine in HIV-seropositive Ugandan adults. METHODS We enrolled HIV-infected adults in Kampala, Uganda without serologic evidence of prior HBV infection. Three HBV vaccine doses were administered at 0, 1 and 6 months. Anti-HBs levels were measured 4 weeks after the third vaccine dose. "Response" to vaccination was defined as anti-HBs levels ≥ 10 IU/L and "high response" as ≥ 100 IU/L. Regression analysis was used to determine predictors of response. RESULTS Of 251 HIV-positive adults screened, 132 (53%) had no prior HBV infection or immunity and were enrolled. Most participants were women [89 (67%)]; median (IQR) age was 32 years (27-41), and 68 (52%) had received antiretroviral therapy (ART) for > 3 months. Median (IQR) CD4 count was 426 (261-583), and 64 (94%) of the 68 receiving ART had undetectable plasma HIV RNA. Overall, 117 (92%) participants seroconverted to the vaccine (anti-HBs ≥ 10 IU/L), with 109 (86%) participants having high-level response (anti-HBs ≥ 100 IU/L). In multivariate analysis, only baseline CD4 > 200 cells/mm3 was associated with response [OR = 6.97 (1.34-34.71), p = 0.02] and high-level response [OR = 4.25 (1.15-15.69)], p = 0.03]. CONCLUSION HBV vaccination was effective in eliciting a protective humoral response, particularly among those with higher CD4 counts. Half of the screened patients did not have immunity to HBV infection, suggesting a large at-risk population for HBV infection among HIV-positive adults in Uganda. Our findings support including HBV vaccination as part of routine care among HIV-positive adults.

Abstract
Tick-borne encephalitis (TBE) is a vector-borne infection associated with a variety of potentially serious complications and sequelae. Vaccination against TBE is strongly recommended for people living in endemic areas. There are two TBE vaccination schemes – standard and rapid – which differ in the onset of protection. With vaccination in a rapid schedule, protection starts as early as 4 weeks after the first dose and is therefore especially recommended for non-immune individuals travelling to endemic areas. Both schemes work reliably in immunocompetent individuals, but only little is known about how TBE vaccination works in people with HIV infection. Our aim was to assess the immunogenicity and safety of the rapid scheme of TBE vaccination in HIV-1 infected individuals. Concentrations of TBE-specific IgG > 126 VIEU/ml were considered protective. The seroprotection rate was 35.7% on day 28 and 39.3% on day 60. There were no differences between responders and non-responders in baseline and nadir CD4 + T lymphocytes. No serious adverse events were observed after vaccination. The immunogenicity of the TBE vaccination was unsatisfactory in our study and early protection was only achieved in a small proportion of vaccinees. Therefore, TBE vaccination with the rapid scheme cannot be recommended for HIV-1 infected individuals.

Abstract
The number of migrants and travellers has grown in recent decades. This phenomenon is also true of people living with HIV, given their much-improved life expectancy and quality of life. A significant number of travellers with HIV are migrants returning to their home countries to visit friends and relatives (VFRs). This population constitutes a high-risk group because they travel for longer and often to rural and remote areas and have closer contact with the local population. In this review we discuss the sociodemographic characteristics of travellers with HIV, the differences between conventional travellers and VFRs, and the risks of HIV acquisition and transmission during travel. We also present the most relevant travel-associated illnesses and highlight the particularities of pre-travel advice given to this population, including immunosuppression, responses to vaccines, high incidence of comorbidities, drug interactions, legal and language barriers. The need to integrate these factors based on far less evidence than that available for the general population makes pre-travel advice for travellers with HIV genuinely challenging.

Abstract
Vaccination is one of the most effective and cost-efficient methods for protecting people with multiple sclerosis (MS) from infections. However, use of vaccines has often been problematic because of misguided concerns that they may exacerbate the disease and/or that some disease-modifying therapies may influence the immune response to immunisations and/or their safety. People with MS risk higher morbidity and mortality from vaccine-preventable infections. It is, therefore, important to address any patient’s reluctance to accept vaccination and to provide clear guidance for clinicians on which vaccinations to consider proactively. We have reviewed the current literature and provide recommendations regarding vaccines in adults with MS, including specific advice regarding vaccination safety in patients receiving—or going to receive—disease-modifying therapies, vaccination during pregnancy, pretravel counselling and patient education.

Abstract
Traditional replicating smallpox vaccines are associated with serious safety concerns in the general population and are contraindicated in immunocompromised individuals. However, this very population remains at greatest risk for severe complications following viral infections, making vaccine prevention particularly relevant. MVA-BN was developed as a non-replicating smallpox vaccine that is potentially safer for people who are immunocompromised. In this phase II trial, 3 MVA-BN dosing regimens were evaluated for safety, tolerability, and immunogenicity in persons with HIV (PWH) who had a history of AIDS. Following randomization, 87 participants who were predominately male and African American received either 2 standard doses on weeks 0 and 4 in the standard dose (SD) group (N = 27), 2 double-standard doses on the same schedule in the double dose (DD) group (N = 29), or 3 standard doses on weeks 0, 4 and 12 in the booster dose (BD) group (N = 31). No safety concerns were identified, and injection site pain was the most commonly reported solicited adverse event (AE) in all groups (66.7%), with no meaningful differences between groups. The incidence of severe (Grade 3) AEs was low across groups and no serious AEs or AEs of special interest considered related to study vaccine were reported. Doubling the standard MVA-BN dose had no significant effect on induction of neutralizing antibodies, with 100% seroconversion and comparable GMTs at week 6 in the SD and DD groups (78.9 and 100.3, respectively). A booster dose significantly increased peak neutralizing titers in the BD group (GMT: 281.1), which remained elevated at 12 months (GMT: 45.3) compared to the SD (GMT: 6.2) and DD (GMT: 10.6) groups. However, based on the immune response previously reported for healthy participants, a third dose (booster) does not appear necessary, even for immunocompromised participants. Clinical Trial Registry Number: NCT02038881.

Abstract
There is little information on the effectiveness of the pneumococcal vaccines (PVs), especially for the pneumococcal conjugate vaccines (PCVs), in HIV-infected patients in the modern antiretroviral era. This is a case–control study where cases were people living with HIV (PLWH) with confirmed pneumococcal infection (CPI) and controls were PLWH without CPI matched with cases by gender and year of HIV diagnosis. The selection process was blinded to the study factor (vaccination). Sample size estimation yielded 61 cases and 183 controls. We analyzed the effect of PV on CPI using Cox proportional-hazards regression model with time-dependent covariates. We included 256 subjects: 64 cases, and 192 controls. PVs had been administered to 115 (45%) patients. Only the modified Charlson Comorbidity Index (HR 1.16, 95%CI 1.06–1.27, P = 0.001) and the CD4 nadir (HR 0.99, 95% CI 0.98–0.99, P = 0.001) were independently associated with CPI. Receipt of PV was not associated with CPI after adjusting in the multivariate model with time protection as a dependent covariate (HR 0.65, 95% CI 0.35–1.32 P = 0.250). We also investigated the influence of different immunization schedules. In an adjusted model, we found no evidence of protection against CPI, including double immunization schedules (HR 0.42 95%CI 0.15–1.19 P = 0.102). In this case–control study, we could not show an association between pneumococcal vaccination and confirmed pneumococcal infection, although a protective effect of particular schedules of immunization cannot be ruled out.

Abstract
Adjuvanted-influenza vaccination is an efficient method for enhancing the immunogenicity of influenza split-virus vaccines for preventing influenza. However, the medical community's understanding of its performance in patients infected with HIV remains limited. To identify the advantages, we conducted a systematic review and meta-analysis with randomized controlled trials (RCTs) and cohort and case-control studies that have the immunogenicity and safety of influenza vaccines in patients infected with HIV as outcomes. We searched six different databases, and 1698 patients infected with HIV in 11 studies were included. Statistical analysis was performed to calculate the pooled standardized mean differences (SMD) or relative risk (RR) and 95% confidence interval (CI). Regarding immunogenicity, the pooled SMD of GMT (Geometric mean titer) for A/H1N1 was 0.61 (95%CI (0.40,0.82)), the pooled RR of seroconversion was 1.34 (95%CI (0.91,1.98)) for the H1N1 vaccine, 1.27(95%CI (0.64,2.52)) for the H3N2 vaccine, 1.19(95%CI (0.97,1.46)) for the B-type influenza vaccine. The pooled RR of seroprotection was 1.61 (95%CI (1.00,2.58)) for the H1N1 vaccine, 1.06 (95%CI(0.83,1.35)) for the H3N2 vaccine, and 1.13(95%CI(0.91,1.41)) for the B-type vaccine. Adjuvanted-influenza vaccination showed good general tolerability in patients infected with HIV, with the only significant increase being the rate of local pain at the injection site (RR = 2.03, 95%CI (1.06,3.86)). In conclusion, all studies evaluating injected adjuvanted influenza vaccination among patients infected with HIV showed acceptable levels of safety and immunogenicity.

Abstract
Background Vaccine-induced memory B-cell (MBC) subsets have distinct roles in the establishment of protective immunity; MBCs expressing nonswitched immunoglobulin M (IgM+ MBCs) replenish the MBC pool, whereas MBCs expressing isotype-switched immunoglobulin (sIg+ MBCs) differentiate into plasma cells upon antigen reencounter. We investigated immunogenicity and MBCs induced by combined 13-valent pneumococcal conjugate vaccine (PCV13) and 23-valent pneumococcal polysaccharide vaccine (PPV23) in human immunodeficiency virus (HIV)-infected adults. Methods Forty HIV-seropositive adults receiving ART with undetectable viral loads were enrolled. Seventeen had a CD4+ T-cell count of ≥400 cells/μL (group A), and 23 had a CD4+ T-cell count of 200-399 cells/μL (group B). All adults received PCV13 and, 1 year later, PPV23. Levels of IgM+ MBCs (defined as polysaccharide [PS]-specific CD19+CD10-CD27+CD21++IgM+ MBCs) and sIg+ MBCs (defined as PS-specific CD19+CD10-CD27+CD21++IgM- MBCs) and antibodies against PS14 and PS3 were measured prior and 1 month after each vaccination. Results Immunization caused a significant increase in PS antibodies, compared with levels at baseline (P < .001). Group B achieved significantly lower titers than group A (P < .05 for both PS14 and PS3). After receipt of PCV13, levels of IgM+ MBCs were unchanged, whereas levels of sIg+ MBCs increased significantly (P < .05 for PS14 and P < .001 for PS3). In contrast, following PPV23 receipt, levels of IgM+ MBCs were significantly reduced, and levels of sIg+ MBCs remained stable. A positive correlation was observed between baseline IgM+ and sIg+ MBC counts 1 month after PCV13 receipt but not after PPV23 receipt. Conclusions PPV23 receipt 12 months after PCV13 receipt improved PCV13 immunogenicity. The reduction in the IgM+ MBC count observed after PPV23 receipt suggests that PPV23 has a depleting effect on PCV13-associated immunological memory. Clinical Trials Registration NCT03041051.

Abstract
BACKGROUND With the advent of highly active antiretroviral drugs for the treatment of human immunodeficiency virus (HIV) it has become possible for people with HIV to travel to destinations that may place them at risk of a number of infectious diseases. Prevention of infections by vaccination is therefore of paramount importance for these travellers. However, vaccine responsiveness in HIV-positive individuals is not infrequently reduced compared to HIV-negative individuals. An understanding of the expected immune responses to vaccines in HIV-positive travellers is therefore important in planning the best approach to a pretravel consultation. METHODS A PubMed search was performed on HIV or acquired immune deficiency syndrome together with a search for specific vaccines. Review of the literature was performed to develop recommendations on vaccinations for HIV-positive travellers to high-risk destinations. RESULTS The immune responses to several vaccines are reduced in HIV-positive people. In the case of vaccines for hepatitis A, hepatitis B, influenza, pneumococcus, meningococcus and yellow fever there is a good body of data in the literature showing reduced immune responsiveness and also to help guide appropriate vaccination strategies. For other vaccines like Japanese encephalitis, rabies, typhoid fever, polio and cholera the data are not as robust; however, it is still possible to gain some understanding of the reduced responses seen with these vaccines. CONCLUSION This review provides a summary of the immunological responses to commonly used vaccines for the HIV-positive travellers. This information will help guide travel medicine practitioners in making decisions about vaccination and boosting of travellers with HIV.

Abstract
Rubella infection is a vaccine preventable disease. Maternal infection during pregnancy may lead to congenital infection and severe foetal malformations. Thanks to antiretroviral therapy, perinatally HIV-infected women have better prognosis and are now experiencing pregnancy. We evaluated the rate of rubella seronegativity in a cohort of HIV perinatally-infected women of childbearing age. A high rate of seronegativity was found in this group as compared to age-matched non-perinatally infected HIV-infected women (34.5% vs 6.90%, p < 0.01). MMR administration before rubella testing was identified in 75.8% of perinatally-infected women (22/29) with a mean of 2 doses (range: 1-3 doses). HIV perinatally-infected women of childbearing age should be screened repeatedly for rubella immunity.

Abstract
Persons with HIV are at increased risk of HPV infection, HPV disease, and HPV-related cancers compared to HIV negative persons. In persons with HIV, immune responses to vaccination are often sub-optimal, and while these improve with ART, they often remain lower and decline more rapidly than in HIV-negative individuals. Although the evidence base to support the immunogenicity of HPV vaccines in HIV + ve persons is reasonable, the evidence base to support the efficacy of HPV vaccines in HIV + ve individuals is inconsistent. There is one study in HIV + ve men who have sex with men (MSM) which showed no effect, and two other studies, one in HIV + ve women and one in HIV + ve adolescents that showed reduced effectiveness. All these effectiveness studies used Gardasil 4 (G4). Two studies in HIV + ve persons have shown superior immunogenicity of Cervarix (which uses a TLR4 agonist adjuvant) compared to G4. Studies of Hepatitis B vaccines in HIV + ve persons have shown that either (i) increased number of doses (ii) increased vaccine dose, or (iii) TLR agonist adjuvanted vaccines, all produce increased immunogenicity compared to standard vaccine regimes. Therefore, questions remain as to optimal HPV vaccine regimes in HIV and further clinical trials with different HPV vaccine regimes are needed.

Abstract
Invasive pneumococcal diseases (IPDs) remain a significant cause of morbidity and mortality in human immunodeficiency virus (HIV)-positive individuals despite the widespread use of highly active antiretroviral therapy (HAART) and availability of pneumococcal vaccines. The aim of this study was to measure temporal trends in incidence and risk factors for IPD (defined as culture of Streptococcus pneumoniae from blood, cerebrospinal fluid or both) in a cohort of HIV-positive patients attending an ambulatory HIV care centre in Dublin, Ireland over a 10-year period 2006-2015. Incidence of IPD was determined as events per 100,000 person-years' follow-up. Poisson regression was used to assess linear trend in incidence over time. A nested case-control study (four controls per case) was undertaken to assess risk factors for IPD. Forty-seven episodes of IPD were identified in 42 HIV-positive individuals (median [IQR] age 38 years [33-43], 69% male, 86% injecting drug users (IDUs), median CD4 T-cell count 213 cells/mm3) over 16,008 person-years' follow-up (overall incidence rate 293/100,000 person-years). Three patients had two episodes and one patient had three episodes of IPD during the study period. The overall case fatality rate was 15% (95% confidence interval [CI] 4-24%). The incidence of IPD per 100,000 person-years decreased from 728 (95% CI, 455-1002), to 242 (95% CI, 120-365) to 82 (95% CI, 40-154) in calendar periods 2006-2008, 2009-2012 and 2013-2015, respectively (p < 0.01 for linear trend). Older age (p = 0.02), male gender (p = 0.05), detectable HIV viral load (p < 0.01) and non-receipt of pneumococcal vaccine (p = 0.03) were associated with IPD while IDU as risk of acquisition of HIV was of borderline significance (p = 0.06). HIV-positive individuals remain at greater risk of IPD compared to the general population. Pneumococcal vaccine should be seen as a priority to ensure optimal protection for HIV-positive patients.

Abstract
BACKGROUND Despite historically high rates of herpes zoster among people living with HIV (PLWH), comparative studies of herpes zoster by HIV serostatus are lacking since the advent of combination antiretroviral therapy and availability of zoster vaccine. METHODS Annual rates (2002-2015) of first-episode herpes zoster and zoster vaccination were calculated for PLWH and uninfected adults in the Veterans Aging Cohort Study and stratified by HIV serostatus and age. Herpes zoster was captured using ICD9 codes and vaccine receipt with procedural codes and pharmacy data. RESULTS Of 45,177 PLWH and 103,040 uninfected veterans, rates of herpes zoster decreased among PLWH (17.6-8.1/1000) over the study period but remained higher than uninfected adults (4.1/1000) at the end of study period. Rates were higher in PLWH with lower CD4 (<200 vs >500 cells/µL: 18.0 vs 6.8/1000) and unsuppressed vs suppressed HIV-1 RNA (21.8 vs 7.1/1000). Restricted to virologically suppressed participants with CD4 >350 cells per microliter, herpes zoster rates were similar among PLWH aged younger than 60 years and aged 60 years and older in 2015 (6.6 vs 6.7/1000) but higher than all uninfected age groups. At study end, cumulative receipt of zoster vaccine for PLWH aged 60 years and older was less than half that of uninfected veterans: 98.7 vs 215.2/1000. CONCLUSIONS Herpes zoster rates among PLWH have markedly decreased, but, even in cART-treated individuals, remain 50% higher than uninfected adults. Lower rates of zoster vaccine receipt combined with high rates of herpes zoster support the need for a safe and effective vaccine against herpes zoster for PLWH, formal zoster vaccine guidelines for PLWH, and consideration for expanded use at younger ages.

Abstract
BACKGROUND Anogenital warts are the second most common sexually transmitted infection diagnosed in sexual health services in England. About 90% of genital warts are caused by human papillomavirus (HPV) types 6 or 11, and half of episodes diagnosed are recurrences. The best and most cost-effective treatment for patients with anogenital warts is unknown. The commonly used treatments are self-administered topical agents, podophyllotoxin (0.15% cream) or imiquimod (5% cream), or cryotherapy with liquid nitrogen. Quadrivalent HPV (qHPV) vaccination is effective in preventing infection, and disease, but whether it has any therapeutic effect is not known. METHODS AND DESIGN To investigate the efficacy of clearance and prevention of recurrence of external anogenital warts by topical treatments, podophyllotoxin 0.15% cream or imiquimod 5% cream, in combination with a three-dose regimen of qHPV or control vaccination. 500 adult patients presenting with external anogenital warts with either a first or subsequent episode of anogenital warts will be entered into this randomised, controlled partially blinded 2 × 2 factorial trial. DISCUSSION The trial is expected to provide the first high-quality evidence of the comparative efficacy and cost-effectiveness of the two topical treatments in current use, as well as investigate the potential benefit of HPV vaccination, in the management of anogenital warts. TRIAL REGISTRATION The trial was registered prior to starting recruitment under the following reference numbers: International Standard Randomized Controlled Trial Number (ISRCTN) Registry - ISRCTN32729817 (registered 25 July 2014); European Union Clinical Trials Register (EudraCT) - 2013-002951-14 (registered 26 June 2013).

Abstract
INTRODUCTION Despite active antiretroviral therapy (ART), community-acquired pneumonia (CAP) remains a major cause of morbidity and mortality among human immunodeficiency virus (HIV)-infected patients and incurs high health costs. Areas covered: This article reviews the most recent publications on bacterial CAP in the HIV-infected population, focusing on epidemiology, prognostic factors, microbial etiology, therapy, and prevention. The data discussed here were mainly obtained from a non-systematic review using Medline, and references from relevant articles. Expert commentary: HIV-infected patients are more susceptible to bacterial CAP. Although ART improves their immune response and has reduced CAP incidence, these patients continue to present increased risk of pneumonia in part because they show altered immunity and because immune activation persists. The risk of CAP in HIV-infected patients and the probability of polymicrobial or atypical infections are inversely associated with the CD4 cell count. Mortality in HIV-infected patients with CAP ranges from 6% to 15% but in well-controlled HIV-infected patients on ART the mortality is low and similar to that seen in HIV-negative individuals. Vaccination and smoking cessation are the two most important preventive strategies for bacterial CAP in well-controlled HIV-infected patients on ART.

Serological responses to revaccination with hepatitis A virus (HAV) vaccines among HIV-positive individuals whose anti-HAV antibody waned after primary vaccination. Liver Int 2018; 38:1198-1205. [PMID: 29240985 DOI: 10.1111/liv.13665] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2017] [Accepted: 12/05/2017] [Indexed: 12/24/2022]
Abstract
BACKGROUND Among HIV-positive individuals, seroprotection for hepatitis A virus (HAV) following primary vaccination may wane with time. However, seroresponses to HAV revaccination are rarely investigated among HIV-positive patients who have lost protective antibodies after primary vaccination. METHODS During the outbreak of acute hepatitis A in Taiwan after June 2015, HAV-seronegative, HIV-positive individuals were advised to receive two doses of HAV vaccines at 24 weeks apart. A retrospective 1:2 matched case-control study was conducted to compare the seroresponses at weeks 4, 24, 28 and 48 of HAV vaccination between those who underwent revaccination after having lost protective antibodies (case patients) and those who underwent primary vaccination (controls). RESULTS Seventy-five case patients and 150 matched controls were included. The serological response rates were consistently higher among the case patients than controls: 88.1% vs 10.5% at week 4 following the first dose of HAV vaccination (P < .001); 93.3% vs 46.0% at week 24 (immediately before the second dose; P < .001); 98.7% vs 62.7% at week 28 (4 weeks after the second dose; P < .001) and 98.7% vs 92.7% at week 48 (P = .06). The anti-HAV antibody titres as reflected by the semi-quantitative assay for the case patients were also significantly higher than the controls at weeks 24, 28 and 48 following HAV vaccination. CONCLUSIONS We demonstrated faster and better serological responses to HAV revaccination among the HIV-positive individuals who had lost their anti-HAV antibodies after primary vaccination. Single dose of HAV revaccination may provide rapid and sufficient seroresponses for HAV during the outbreak of acute hepatitis A.

Abstract
Vaccination has been associated with a transient increase in viremia in HIV-infected individuals, although contradicting evidence persist in the literature. As part of a randomized placebo-controlled efficacy trial of the PCV7 in Malawi, we collected viral load and CD4+ T-cell counts from 237 adults who received two doses of vaccine or placebo, administered 4 weeks apart. Analyses were conducted separately for cART and non-cART users. Our analysis show no difference in viral loads between vaccine and placebo groups, regardless of cART use. Viremia decreased from 4.1 to 2.9 log10 copies/mL (p < 0.0001) among those using cART, consistent vaccine and placebo groups, but no changes were seen among the non-cART cohort. CD4+ T-cell counts remained unchanged regardless of cART use, or allocation to vaccine or placebo. We concluded that there was no evidence of detrimental effects of PCV7 administration on viral load or CD4+ T-cell counts six months after vaccination with PCV7.

Abstract
BACKGROUND An unprecedented outbreak of acute hepatitis A has occurred among MSM in Taiwan since June 2015. We aimed to describe the seroepidemiology of HAV infection and to investigate the relationship between HAV vaccination and the incidence of acute hepatitis A among HIV-positive patients at the largest designated hospital for HIV care during the outbreak. METHODS Between 2012 and 2016, the HAV serostatus, vaccination history and clinical characteristics of HIV-positive patients were retrospectively reviewed. A case-control study was performed to identify the factors associated with acute hepatitis A. The trends of HAV vaccination rate and incidence of acute hepatitis A among HAV-seronegative patients were examined during the outbreak. RESULTS During the 4.5-year period, 2088 HIV-positive patients with a mean age of 37.7 years and 90.2% being MSM were included. The overall HAV seroprevalence was 34.3%, which was significantly higher in older and non-MSM patients. The estimated incidence rate of acute hepatitis A was 52.6 cases per 1000 person-years of follow-up during the outbreak. The associated factors with acquiring acute hepatitis A were recent syphilis and having not received HAV vaccines. The HAV vaccination rate during the outbreak increased from 4.7% to 70.6% and the incidence rate of acute hepatitis A declined when up to 65% of the patients were immunized or tested positive for HAV. CONCLUSIONS The seroprevalence of HAV infection was low in the younger HIV-positive individuals. Prevention of acute hepatitis A was achieved among HIV-positive, HAV-seronegative patients through HAV vaccination and increased herd immunity during the ongoing outbreak.

Abstract
OBJECTIVES Measles infection is a vaccine-preventable disease currently resurging in Europe. HIV-infected subjects are at higher risk of complications following measles infection. We investigated the risk factors associated with being seronegative in a cohort of HIV-infected subjects. METHODS All HIV-infected subjects in our cohort who had a measles serological test performed between December 2005 and May 2017 were retrospectively identified. A measles immunoglobulin G (IgG) titre > 275 mIU/mL was considered protective. Risk factors were analysed using logistic regression. RESULTS Measles serology was available in 273 of 3124 subjects in active follow-up (8.7%). The prevalence of measles seronegativity was 21.6% (59 of 273). In the univariate analysis, being born after 1970 and HIV infection by vertical transmission were both associated with a higher risk of measles seronegativity, while a nadir CD4 T-cell count < 200 cells/μL was associated with a lower risk of measles seronegativity. In the multivariate analysis, only being born after 1970 [odds ratio (OR) 4.9; 95% confidence interval (CI) 1.3-18.7] and vertical transmission (OR 7.7; 95% CI 3.3-18.3) were significantly associated with seronegativity. Among the vertically infected subjects with measles-mumps-rubella (MMR) immunization documentation, the median number of doses of vaccine received before testing was 2 (range 1-3). CONCLUSIONS HIV-infected subjects born after 1970 and vertically infected subjects should be screened for measles seropositivity.

Abstract
Advancements in medicine have led to a considerable increase in the proportion of patients living with severe chronic diseases, malignancies, and HIV infections. Most of these conditions are associated with acquired immune-deficient states and treatment-related immunosuppression. Although infections as a result of neutropenia have long been recognized and strategies for management were developed, non-neutropenic immunosuppression has been overlooked. Recently, community-acquired infections in patients with frequent, significant exposure to healthcare settings and procedures have been classified as 'healthcare-associated infections' since they are more similar to hospital-acquired infections. Most of the non-neutropenic immunosuppressed patients have frequent contact with the healthcare system due to their chronic and severe diseases. In this review, we focus on the healthcare-associated bloodstream infections in the most common non-neutropenic immunosuppressive states and provide an update of the recent evidence for the management of these infections.
