RESUMEN

Influenza infection increases the risk of cardiovascular complications and mortality in patients with heart disease. In patients with coronary artery disease influenza vaccination has been shown to reduce cardiovascular mortality, but high-quality evidence was missing. New trial data from a RCT in patients shortly after myocardial infarction has confirmed the significant reduction of the risk of major adverse cardiovascular events (MACE) and cardiovascular death after influenza vaccination. Also in patients with heart failure the first published RCT in heart failure shows a clinical benefit of influenza vaccination versus placebo during the influenza season, confirming preceding observational studies. Meta-analyses from the study data estimate that after influenza vaccination a risk reduction of MACE of at least 25% is possible in patients with heart disease. The current underutilization of influenza vaccines in heart patients should be addressed because influenza vaccination has proven to be an effective and safe instrument for secondary prevention.

RESUMEN

Monkeypox (MPX) is a disease caused by the monkeypox virus. It is a viral zoonotic disease, endemic in Central and West Africa. Human-to-human spread also occurs and is a feature of the current global outbreak. As far as we know, exponential transmission during this outbreak is not related to changed viral characteristics but due to multiple high-risk contacts in a subset of people that have contracted the virus, so far almost exclusively affecting men who have sex with men (MSM). Appropriate public health measures and increased alertness of all health care providers is needed to increase case-finding and decrease transmission. There is a real chance of MPX to become endemic in large parts of the world.

RESUMEN

People living with HIV (PLWH) are at increased risk of pneumococcal infections compared with the general population. The objective of this study was to investigate the immunogenicity of the combined pneumococcal vaccination schedule in PLWH. In this prospective cohort study, adult PLWH on antiretroviral therapy and HIV-negative controls received the 13-valent pneumococcal conjugate vaccine (PCV13) at baseline followed by the 23-valent pneumococcal polysaccharide vaccine (PPSV23) at Month 2. Serotype-specific IgG levels of 24 vaccine serotypes were measured at Months 0, 2, 4, 6 and 12. The primary outcome was seroprotection at Month 4, defined as the proportion of patients with a post-immunisation IgG concentration of ≥1.3 µg/mL for ≥70% (17/24) of vaccine serotypes. Samples of 120 patients were analysed. Seroprotection at Month 4 was 49% (39/80) for PLWH and 82% (28/34) in controls. At Month 12, seroprotection had decreased to 23% (18/79) and 63% (22/35), respectively. Nadir CD4 count ≥200 cells/mm3, preserved kidney function and co-administration of the diphtheria-tetanus-polio (DTP) vaccine were associated with better seroprotection among PLWH. IgG levels both of PLWH and controls (all 24 vaccine serotypes) were significantly higher compared with baseline at all timepoints. Although IgG levels of all 24 vaccine serotypes increased significantly both in PLWH and controls, only a minority of PLWH achieved seroprotection after PCV13 followed by PPSV23. In addition, protective immunity waned rapidly. Further research into alternative vaccinations strategies for PLWH is needed, such as vaccination schedules with higher-valent pneumococcal vaccines. The DTP vaccine may augment pneumococcal vaccination responses.

RESUMEN

Immunosuppressive therapy increases the risk of pneumococcal disease. This risk can be mitigated by pneumococcal vaccination. The objective of this study was to investigate the immunogenicity of the 13-valent pneumococcal conjugate vaccine (PCV13), followed by the 23-valent pneumococcal polysaccharide vaccine (PPSV23), in adults with and without immunosuppressive therapy. We performed a prospective cohort study among adults using conventional immunomodulators (cIM), biological immunomodulators (bIM), combination therapy, and controls during 12 months. The primary outcome was seroprotection, defined as the proportion of patients with a postimmunization IgG concentration of ≥1.3 µg/mL for at least 70% (17/24) of the serotypes of PCV13 + PPSV23. We included 214 participants. For all 24 vaccine serotypes, IgG levels increased significantly in both treatment subgroups and controls, with peak seroprotection rates of 44% (combination therapy), 58% (cIM), 57% (bIM), and 82% (controls). By month 12, seroprotection had decreased to 24%, 48%, 39%, and 63%, respectively. Although pneumococcal vaccination with PCV13 + PPSV23 was immunogenic in all treatment groups, impaired vaccination responses were observed in patients using immunosuppressive medication. Apart from the obvious recommendation to administer vaccines before such medication is started, alternative vaccination strategies, such as additional PCV13 doses or higher-valent pneumococcal vaccines, should be investigated.

RESUMEN

INTRODUCTION: Toxoplasma gondii (T. gondii) is an obligate intracellular parasite that is estimated to be carried by one-third of the world population. Latent T. gondii infection has been linked to several neuropsychiatric mood disorders and behaviors. The aim of the present study was to examine whether T. gondii seropositivity is associated with affective disorders, as well as with aggression reactivity and suicidal thoughts. METHODS: In the Netherlands Study of Depression and Anxiety (NESDA), T. gondii antibodies were assessed in patients with current depressive (n â€‹= â€‹133), anxiety (n â€‹= â€‹188), comorbid depressive and anxiety (n â€‹= â€‹148), and remitted disorders (n â€‹= â€‹889), as well as in healthy controls (n â€‹= â€‹373) based on DSM-IV criteria. Seropositivity was analyzed in relation to disorder status, aggression reactivity and suicidal thoughts using multivariate analyses of covariance and regression analyses. RESULTS: Participants were on average 51.2 years (SD â€‹= â€‹13.2), and 64.4% were female. Seropositivity was found in 673 participants (38.9%). A strong positive association between T. gondii seropositivity and age was observed. No significant associations were found between T. gondii seropositivity and disorder status, aggression reactivity and suicidal thoughts. The adjusted odds ratio (OR) for any remitted disorder versus controls was 1.13 (95% CI: 0.87-1.49), and for any current disorder versus controls was 0.94 (95% CI: 0.69-1.28). CONCLUSIONS: No evidence was found for a relationship between affective disorders and T. gondii infection in the current sample.

RESUMEN

BACKGROUND: The objective of this systematic review and meta-analysis was to summarise the literature regarding the immunogenicity of pneumococcal conjugate vaccines (PCV) and pneumococcal polysaccharide vaccines (PPSV) in adult people living with HIV (PLWH) in the era of advanced combination antiretroviral therapy (cART). METHODS: The systematic review protocol was published online (PROSPERO ID: CRD 42020153137). We searched Medline (Ovid), EMBASE (Ovid), and the Global Health Library for publications from 2000 to June 11, 2020. We included all studies in adult PLWH that reported vaccine immunogenicity outcomes. The primary outcome was seroconversion rate (SCR) after PCV, PPSV and PCV/PPSV combined. For random-effects meta-analysis, we included studies defining SCR as a ≥ 2-fold increase in IgG from baseline, and reporting SCR for serotypes 6B, 14, or overall SCR, 1-3 months after vaccination. FINDINGS: Our search identified 1597 unique studies, of which 115 were eligible for full-text assessment. Of these, 39 met the inclusion criteria (11 RCTs; 28 cohort studies). A high degree of heterogeneity was observed. Nineteen studies were included in the meta-analysis. Pooled overall SCRs were 42% (95% CI 30-56%), 44% (95% CI 33-55%) and 57% (95% CI 50-63%) for PLWH who received PPSV, PCV or a combination of PCV/PPSV, respectively. Compared to PPSV alone, a combination of PCV/PPSV yielded higher SCRs (OR 2.24 95% CI 1.41- 3.58), whereas we did not observe a significant difference in SCR between PCV and PPSV23 alone. There were no statistically significant differences in geometric mean post-vaccination antibody concentrations between vaccination schedules. Vaccination at higher CD4 cell counts improved immunogenicity in 8/21 studies, especially when PCV was administered. No studies assessed the long-term immunogenicity of PCV followed by PPSV23. Quality of evidence ranged from poor (n = 19) to good quality (n = 7). A limited number of pneumococcal serotypes was assessed in the majority of studies. INTERPRETATION: We show that the recommended immunisation schedule consisting of a combination of PCV13/PPSV23, is immunogenic in PLWH in the era of advanced cART. However, the durability of this vaccination schedule remains unknown and must be addressed in future research. Vaccination with PCV should be delayed until immunological recovery (CD4>200) in recently diagnosed PLWH for optimal immunogenicity. The evidence gathered here supports wide implementation of the combination of PCV/PPSV23 for all PLWH. We recommend reassessment of this strategy once higher-valent PCVs become available. FUNDING: HMGG is funded by a public research grant of ZonMw (project number 522004005).

RESUMEN

Much has changed in the medical treatment of COVID-19 after the first patient with an infection with SARS-CoV-2 in the Netherlands was diagnosed in February 2020. On the basis of limited data, at first only off-label use of (hydroxy)chloroquine seemed to be a treatment option. However, now based on the findings of several randomized studies, other medicines have been included in the Dutch guidelines about the treatment of COVID-19. In this article, we will briefly discuss the current state of affairs with regard to the drugs (hydroxy) chloroquine, remdesivir and corticosteroids. Again, it appears that only well-executed randomized clinical trials can determine the status of various supposedly effective drugs.

RESUMEN

Immunocompromised individuals are at increased risk of infectious diseases and their complications. The main examples of these are pneumococcal disease and influenza, infections that are both vaccine-preventable. However, responses to vaccination are often impaired in immunocompromised patients. In addition, live-attenuated vaccines, including the measles-mumps-rubella and yellow fever vaccine, cannot be administered to these patients for safety reasons. In view of the decreasing herd immunity caused by a drop in global vaccination coverage, immunocompromised individuals are at increased risk of infections such as measles, especially during travel abroad. Despite these developments, the improved quality of life resulting from novel treatment options means that immunocompromised patients are travelling more and further than ever. It is the responsibility of the treating physician of the immunocompromised individual to ensure that all the required vaccines are provided in time. To this end, the physician may also refer the patient to the general practitioner or travel clinic for the actual vaccination.

RESUMEN

BACKGROUND: Although people living with human immunodeficiency virus (PLWH) are at increased risk of invasive pneumococcal disease (IPD) and community-acquired pneumonia (CAP), it is unclear whether this remains the case in the setting of early initiation of combination antiretroviral therapy (cART), at high CD4 cell counts. This is important, as pneumococcal vaccination coverage in PLWH is low in Europe and the United States, despite longstanding international recommendations. METHODS: We identified all CAP and IPD cases between 2008 and 2017 in a cohort of PLWH in a Dutch HIV referral center. We calculated incidence rates stratified by CD4 count and cART status and conducted a case-control study to identify risk factors for CAP in PLWH receiving cART. RESULTS: Incidence rates of IPD and CAP in PLWH were 111 and 1529 per 100 000 patient-years of follow-up (PYFU). Although IPD and CAP occurred more frequently in patients with CD4 counts <500 cells/µL (incidence rate ratio [IRR], 6.1 [95% confidence interval, 2.2-17] and IRR, 2.4 [95% confidence interval, 1.9-3.0]), the incidence rate in patients with CD4 counts >500 cells/µL remained higher compared with the general population (946 vs 188 per 100 000 PYFU). All IPD isolates were vaccine serotypes. Risk factors for CAP were older age, CD4 counts <500 cells/µL, smoking, drug use, and chronic obstructive pulmonary disease. CONCLUSIONS: The incidence of IPD and CAP among PLWH remains higher compared with the general population, even in those who are virally suppressed and have high CD4 counts. With all serotyped IPD isolates covered by pneumococcal vaccines, our study provides additional argumentation against the poor current adherence to international recommendations to vaccinate PLWH.

RESUMEN

Revision of the rabies policy in the Netherlands The WHO aims to eliminate dog-transmitted rabies deaths in humans by 2030 ('zero by 30'). The Dutch rabies policy advisory board has revised its national rabies guidelines on the basis of the WHO guidelines revised in 2018. In the revised Dutch guidelines, there is increased focus on the importance of instant wound care after potential exposure to the rabies virus. Pre-exposure prophylaxis (PrEP) is limited to two vaccines given on days 0 and 7, rather than the previous regime of three vaccines. Post-exposure prophylaxis (PEP) no longer consists of five vaccines for unvaccinated individuals; instead it is four vaccines on days 0, 3, 7, and 14-28. For type III wounds, when indicated, rabies immunoglobulin (RIG) is only injected into and around the wound bed; residual volumes are no longer administered intramuscularly. RIG no longer needs to be administered in cases of potential mucosal contact exposure to the rabies virus where there is no injury. The vaccination scheme for PrEP (3) and PEP (5) does not change for immunocompromised patients, and RIG is administered regardless of the vaccination status of the affected individual.

RESUMEN

BACKGROUND: Influenza vaccination is recommended in patients with cancer to reduce influenza-related complications. Recently, more immune-related adverse events (irAEs) were demonstrated in patients with lung cancer who were vaccinated with the trivalent seasonal influenza vaccine during anti-programmed death receptor 1 (PD-1) immunotherapy. Confirmation of these findings is essential before recommendations on influenza vaccination may be revoked. METHODS: In this cohort study in patients with lung cancer receiving nivolumab 3 mg/kg every 2 weeks during two influenza seasons (2015/16-2016/17), irAEs have been monitored. Incidence, timing and severity of irAEs were compared between vaccinated patients and non-vaccinated patients. FINDINGS: In a compassionate use programme, 127 patients with lung cancer had been treated with at least one dose of nivolumab during two national influenza vaccination campaigns from September until December of 2015 and 2016. Forty-two patients had received the influenza vaccine, and 85 patients were not vaccinated. Median follow-up period was 118 days (interquartile range 106-119). Mean age was 64 years (range 46-83). In vaccinated and non-vaccinated patients, the incidence of irAEs was 26% and 22%, respectively, rate ratio 1.20 (95% confidence interval [CI] 0.51-2.65). The incidence of serious irAEs was 7% and 4%, respectively, rate ratio 2.07 (95% CI 0.28-15.43). Influenza vaccination while receiving nivolumab did not result in significant differences in the rates of discontinuation, death, clinical deterioration or tumour response between the groups. INTERPRETATION: Influenza vaccination in patients with lung cancer receiving anti-PD-1 immunotherapy does not induce irAEs in our cohort. With this result, influenza vaccination should not be deterred from this group of patients.

RESUMEN

BACKGROUND: There is a lack of severity assessment tools to identify adults presenting with febrile urinary tract infection (FUTI) at risk for complicated outcome and guide admission policy. We aimed to validate the Prediction Rule for Admission policy in Complicated urinary Tract InfeCtion LEiden (PRACTICE), a modified form of the pneumonia severity index, and to subsequentially assess its use in clinical practice. METHODS: A prospective observational multicenter study for model validation (2004-2009), followed by a multicenter controlled clinical trial with stepped wedge cluster-randomization for impact assessment (2010-2014), with a follow up of 3 months. Paricipants were 1157 consecutive patients with a presumptive diagnosis of acute febrile UTI (787 in validation cohort and 370 in the randomized trial), enrolled at emergency departments of 7 hospitals and 35 primary care centers in the Netherlands. The clinical prediction rule contained 12 predictors of complicated course. In the randomized trial the PRACTICE included guidance on hospitalization for high risk (>100 points) and home discharge for low risk patients (<75 points), in the control period the standard policy regarding hospital admission was applied. Main outcomes were effectiveness of the clinical prediction rule, as measured by primary hospital admission rate, and its safety, as measured by the rate of low-risk patients who needed to be hospitalized for FUTI after initial home-based treatment, and 30-day mortality. RESULTS: A total of 370 patients were included in the randomized trial, 237 in the control period and 133 in the intervention period. Use of PRACTICE significantly reduced the primary hospitalization rate (from 219/237, 92%, in the control group to 96/133, 72%, in the intervention group, p < 0.01). The secondary hospital admission rate after initial outpatient treatment was 6% in control patients and 27% in intervention patients (1/17 and 10/37; p < 0.001). CONCLUSIONS: Although the proposed PRACTICE prediction rule is associated with a lower number of hospital admissions of patients presenting to the ED with presumptive febrile urinary tract infection, futher improvement is necessary to reduce the occurrence of secondary hospital admissions.

RESUMEN

BACKGROUND: In adults with febrile urinary tract infection (fUTI), data on optimal treatment duration in patients other than non-pregnant women without comorbidities are lacking. METHODS: A randomized placebo-controlled, double-blind, non-inferiority trial among 35 primary care centers and 7 emergency departments of regional hospitals in the Netherlands. Women and men aged ≥ 18 years with a diagnosis of fUTI were randomly assigned to receive antibiotic treatment for 7 or 14 days (the second week being ciprofloxacin 500 mg or placebo orally twice daily). Patients indicated to receive antimicrobial treatment for at least 14 days were excluded from randomization. The primary endpoint was the clinical cure rate through the 10- to 18-day post-treatment visit with preset subgroup analysis including sex. Secondary endpoints were bacteriologic cure rate at 10-18 days post-treatment and clinical cure at 70-84 days post-treatment. RESULTS: Of 357 patients included, 200 were eligible for randomization; 97 patients were randomly assigned to 7 days and 103 patients to 14 days of treatment. Overall, short-term clinical cure occurred in 85 (90%) patients treated for 7 days and in 94 (95%) of those treated for 14 days (difference -4.5%; 90% CI, -10.7 to 1.7; P non-inferiority = 0.072, non-inferiority not confirmed). In women, clinical cure was 94% and 93% in those treated for 7 and 14 days, respectively (difference 0.9; 90% CI, -6.9 to 8.7, P non-inferiority = 0.011, non-inferiority confirmed) and, in men, this was 86% versus 98% (difference -11.2; 90% CI -20.6 to -1.8, P superiority = 0.025, inferiority confirmed). The bacteriologic cure rate was 93% versus 97% (difference -4.3%; 90% CI, -9.7 to 1.2, P non-inferiority = 0.041) and the long-term clinical cure rate was 92% versus 91% (difference 1.6%; 90% CI, -5.3 to 8.4; P non-inferiority = 0.005) for 7 days versus 14 days of treatment, respectively. In the subgroups of men and women, long-term clinical cure rates met the criteria for non-inferiority, indicating there was no difference in the need for antibiotic retreatment for UTI during 70-84 days follow-up post-treatment. CONCLUSIONS: Women with fUTI can be treated successfully with antibiotics for 7 days. In men, 7 days of antibiotic treatment for fUTI is inferior to 14 days during short-term follow-up but it is non-inferior when looking at longer follow-up. TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov [ NCT00809913 ; December 16, 2008] and trialregister.nl [ NTR1583 ; December 19, 2008].

RESUMEN

Patients with solid tumours receiving chemotherapy are at risk for influenza complications. Yearly influenza vaccination is recommended to patients treated with chemotherapy. However, adherence to vaccination is low, most likely due to lack of data on efficacy, optimal timing and safety of vaccination. There is scarce evidence for the effectiveness of the influenza vaccine in adult patients with solid tumours and chemotherapy on reduction of pneumonia, decreased mortality and fewer interruptions of oncological treatment. A review of 20 non-randomised serological studies in adult patients with different cancer types and chemotherapy provides insight in general trends of response to vaccination. Overall, the magnitude of the antibody response after influenza vaccination (i.e. seroconversion) can be lower than in healthy controls, but the majority of patients with solid tumours is able to mount a timely, protective immunological response (i.e. seroprotection) regardless of chemotherapy schedule, similar to healthy controls. Small sample sizes, patient heterogeneity and lack of comparable study designs limit more specific recommendations related to cancer type and optimal timing of vaccination. The inactivated influenza vaccine is safe to administer to immunosuppressed patients; side-effects are similar to those in healthy individuals. Although vaccination before start of chemotherapy is preferred to ensure optimal protection in adults with solid tumours, also vaccination during chemotherapy can reduce influenza-related complications considering the overall trends in serological response. Given the increased morbidity and mortality of influenza, influenza vaccination should be advocated as an inexpensive and safe preventive measure in patients with solid tumours receiving chemotherapy.

RESUMEN

BACKGROUND: Typhoid fever, caused by the Gram-negative bacterium Salmonella enterica serovar Typhi, is a major cause of community-acquired bacteremia and death worldwide. S100A8 (MRP8) and S100A9 (MRP14) form bioactive antimicrobial heterodimers (calprotectin) that can activate Toll-like receptor 4, promoting lethal, endotoxin-induced shock and multi-organ failure. We aimed to characterize the expression and function of S100A8/A9 in patients with typhoid fever and in a murine invasive Salmonella model. METHODS AND PRINCIPAL FINDINGS: S100A8/A9 protein levels were determined in acute phase plasma or feces from 28 Bangladeshi patients, and convalescent phase plasma from 60 Indonesian patients with blood culture or PCR-confirmed typhoid fever, and compared to 98 healthy control subjects. To functionally characterize the role of S100A8/A9, we challenged wildtype (WT) and S100A9-/- mice with S. Typhimurium and determined bacterial loads and inflammation 2- and 5- days post infection. We further assessed the antimicrobial function of recombinant S100A8/A9 on S. Typhimurium and S. Typhi replication in vitro. Typhoid fever patients demonstrated a marked increase of S100A8/A9 in acute phase plasma and feces and this increases correlated with duration of fever prior to admission. S100A8/A9 directly inhibited the growth of S. Typhimurium and S. Typhi in vitro in a dose and time dependent fashion. WT mice inoculated with S. Typhimurium showed increased levels of S100A8/A9 in both the liver and the systemic compartment but S100A9-/- mice were indistinguishable from WT mice with respect to bacterial growth, survival, and inflammatory responses, as determined by cytokine release, histopathology and organ injury. CONCLUSION: S100A8/A9 is markedly elevated in human typhoid, correlates with duration of fever prior to admission and directly inhibits the growth of S. Typhimurium and S. Typhi in vitro. Despite elevated levels in the murine invasive Salmonella model, S100A8/A9 does not contribute to an effective host response against S. Typhimurium in mice.

RESUMEN

BACKGROUND: When assessing health status, physicians may focus on objective symptoms and diagnoses, whereas individuals may focus more on subjective symptoms, functional limitations and quality of life. METHODS: In the Zutphen Elderly Study, 710 community-living men (aged 64-84 years) were followed until death for 15 years. Self-rated health was assessed through a single-item question. Physician-rated health was estimated on a Likert scale by physicians after medical history assessment and physical examination. Both health ratings were categorised into three groups. All-cause, cardiovascular and cancer mortality rates were analysed in Cox proportional-hazards models. RESULTS: There were 352 (49.6%) men who felt healthy and 225 (31.7%) men with a good physician-rated health. During 15 years of follow-up 503 of 710 men (70.8%) died, of whom 229 (45.5%) from cardiovascular causes and 144 (28.6%) from cancer. Self-rated and physician-rated health both predicted independently all-cause mortality (hazard ratios [HR] for worst vs. best health category: 1.72; 95% confidence interval [CI]: 1.26-2.33, and 1.77; 95% CI: 1.36-2.29; respectively; P-values of <0.005). When self-rated and physician-rated health were discordant, mortality risk was highest when physicians had a less favourable view on the health status than the participant. Self-rated health predicted independently cancer mortality (HR 2.41), whereas physician-rated health cardiovascular mortality (HR 2.13). CONCLUSION: Self-rated and physician-rated health status predicted both all-cause mortality, and showed a differential pattern for cancer and cardiovascular diseases mortality.
