Invasive Infections

The WHO recently endorsed an ambitious plan, “Defeating Meningitis by 2030”, that aims to control/eradicate invasive bacterial infection epidemics by 2030. Vaccination is one of the pillars of this road map, with the goal to reduce the number of cases and deaths due to Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae and Streptococcus agalactiae. The risk of developing invasive bacterial infections (IBI) due to these bacterial species includes genetic and acquired factors that favor repeated and/or severe invasive infections. We searched the PubMed database to identify host risk factors that increase the susceptibility to these bacterial species. Here, we describe a number of inherited and acquired risk factors associated with increased susceptibility to invasive bacterial infections. The burden of these factors is expected to increase due to the anticipated decrease in cases in the general population upon the implementation of vaccination strategies. Therefore, detection and exploration of these patients are important as vaccination may differ among subjects with these risk factors and specific strategies for vaccination are required. The aim of this narrative review is to provide information about these factors as well as their impact on vaccination against the four bacterial species. Awareness of risk factors for IBI may facilitate early recognition and treatment of the disease. Preventive measures including vaccination, when available, in individuals with increased risk for IBI may prevent and reduce the number of cases.

Background. Pneumonia is a condition, where bacterial infections are implicated as the most common causes of morbidity and mortality in humans. The actual burden of HIV-infected patients with pneumonia is not well documented in Mekelle region of Ethiopia. This study estimated the prevalence of bacterial pneumonia in HIV patients, antimicrobial susceptibility patterns of pathogens implicated in pneumonia, and associated risk factors in Mekelle zone, Tigray, Northern Ethiopia, during August-December 2016. Methods. Sputum specimens were collected from 252 HIV seropositive individuals with suspected pneumonia. Data on sociodemographics and risk factors were also collected using a structured questionnaire. Blood, Chocolate, and Mac Conkey agar plates (Oxoid, Hampshire, UK) were used to grow the isolates. The isolated colonies were identified based on Gram stain, colony morphology, pigmentation, hemolysis, and biochemical tests. The antimicrobial susceptibility test was performed using the modified Kirby-Bauer disc diffusion method. The analysis was performed using SPSS version 22 and p-value < 0.05 with corresponding 95% confidence interval (CI) was considered statistically significant. Results. Out of the 252 samples, 110 (43.7%) were positive for various bacterial species. The predominant bacterial species were Klebsiella pneumoniae (n=26, 23.6 %) followed by Streptococcus pneumoniae (n=17, 15.5 %), Escherichia coli (n=16, 14.5%), Klebsiella spp. (n=15, 13.6%), Staphylococcus aureus (n=9, 8.2%), Enterobacter spp. (n=7, 6.3%), Pseudomonas aeruginosa (4, n=3.6%), Proteus spp. (n=4, 3.6%), Citrobacter freundii (n=7, 6.3%), Streptococcus pyogenes (3, 2.7%), and Haemophilus influenzae (n=2, 1.8%). Young age (18-29), recent CD4+ count less than 350 cells/mL, alcohol consumption, and HIV WHO stage II showed significant association with the occurrence of bacterial pneumonia. Resistance to penicillin, co-trimoxazole, and tetracycline was observed in 81.8%, 39.8%, and 24.5% of the isolates, respectively. Conclusions. The problem of pneumonia among HIV patients was significant in the study area. The high prevalence of drug-resistant bacteria isolated from the patient’s samples possesses a health risk in immunocompromised HIV patients. There is a need to strengthen and expand culture and susceptibility procedures for the administration of appropriate therapy to improve patients management and care which may aid in decreasing the mortality.

Abstract BACKGROUND: Recent EBMT analysis showed that infections are responsible for 21% of deaths after allo-HCT and 11% after auto-HCT. However, the risk, types and outcome of infections vary between age groups. The aim of the study is the direct comparison of risk factors of incidence and outcome of infections in children and adults. PATIENTS AND METHODS: We analyzed risk factors for the incidence and outcome of bacterial, fungal, and viral infections in 650 children and 3200 adults who received HCT between 2012-2015. The risk factors were determined by multivariable logistic regression analysis. RESULTS: A total number of 395/650 (60.8%) children and 1122/3200 (35.0%) adults were diagnosed for microbiologically confirmed infection, including 345/499 (69.1%) and 679/1070 (63.5%), respectively after allo-HCT, and 50/151 (33.1%) and 443/2130 (20.8%) respectively, after auto-HCT. At 2 years after HCT, the incidences of microbiologically documented bacterial infection were 36.0% and 27.6%, (p<0.001) for children and adults, respectively. Incidences of proven/probable invasive fungal disease (IFD) were 8.4% and 3.7% (p<0.001), respectively; and incidences of viral infection were 38.3%, and 13.5% (p<0.001), respectively. Overall, 31/650 (4.8%) children and 206/3200 adults (6.4%) have died after these infections. The distribution of deaths was different in children (35.5% bacterial, 48.4% fungal, 16.1% viral) and adults (61.7% bacterial, 24.7% fungal, 13.6% viral). BACTERIAL INFECTIONS: In multivariable analysis, the risk of infections was higher after allo-HCT (HR=1.8; p<0.001). In allo-HCT patients, the risk was higher in children (HR=2.1; p<0.001), in patients with acute leukemia (HR=1.6; p<0.001), matched unrelated (MUD) vs matched family-donor (MFD) HCT (HR=1.6; p<0.001), mismatched unrelated (MMUD) vs MFD HCT (HR=2.0; p<0.001), myeloablative vs reduced-intensity conditioning (RIC) (HR=1.3; p<0.001), delayed (>21d) hematological recovery (HR=3.3; p<0.001), acute GVHD before infection (HR=1.7; p<0.001), and chronic GVHD before infection (HR=1.4; p=0.014). In auto-HCT patients, the risk was higher in children (HR=1.7; p<0.001), and in patients with delayed hematological recovery (HR=2.8; p<0.001). In patients with multiple myeloma (MM) the risk was decreased (HR=0.7; p=0.005). FUNGAL INFECTIONS: The risk of proven/probable IFD was higher after allo-HCT (HR=5.4; p<0.001). In allo-HCT patients, the risk was higher in children (HR=3.9; p<0.001), in patients with acute leukemia (HR=3.8; p<0.001), MUD vs MFD HCT (HR=1.5; p=0.013), MMUD vs MFD HCT (HR=2.5; p<0.001), delayed hematological recovery (HR=3.3; p<0.001), acute GVHD before infection (HR=1.5; p=0.021), and chronic GVHD before infection (HR=2.2; p<0.001). In auto-HCT patients, the risk was higher in children (HR=1.8; p=0.025). Patients with MM were at decreased risk of IFD (HR=0.6; p=0.005). VIRAL INFECTIONS: In multivariable analysis, the risk of infections was higher after allo-HCT (HR=6.1; p<0.001). In allo-HCT patients, the risk was higher in children (HR=1.3; p=0.010), in patients with acute leukemia (HR=1.7; p<0.001), MUD vs MFD HCT (HR=2.0; p<0.001), MMUD vs MFD HCT (HR=3.3; p<0.001), myeloablative vs RIC (HR=1.8; p=0.050), acute GVHD before infection (HR=1.5; p<0.001) and chronic GVHD before infection (HR=2.7; p=0.014). Among auto-HCT patients, diagnosis of MM brought decreased risk of viral infections (HR=0.5; p<0.001). DEATH FROM INFECTION: In allo-HCT patients, adults (HR=3.3; p<0.001), recipients of MMUD-HCT (HR=3.8; p<0.001), patients with acute leukemia (HR=1.5; p=0.023), chronic GVHD before infection (HR=3.6; p=0.014), CMV reactivation (HR=1.4; p=0.038) and with duration of infection treatment >21 days (HR=1.4; p=0.038) were associated with increased risk of death from infection. Among patients with bacterial infections, the risk was higher in G- infections (HR=1.6; p=0.031). Among auto-HCT patients, no child died of infection. In adults, the risk of death was higher if duration of treatment of infection was >21 days (HR=1.7; p<0.001). In patients with MM the risk was decreased (HR=0.4; p<0.001). CONCLUSIONS: The profile of infections and related deaths varies between children and adults. MMUD transplants, diagnosis of acute leukemia, chronic GVHD, CMV reactivation and prolonged infection are relative risk factors for death from infection after HCT.

Abstract Background Bipolar disorders (BD) belong to the most severe mental disorders, characterized by an early onset, predominantly recurrent/chronic course and poor psychosocial functioning. Many patients with BD experience substantial symptomatology months or even years before full BD manifestation. Adequate diagnosis and treatment is often delayed, which is associated with a worse outcome. This study aims to prospectively evaluate and improve early recognition and intervention strategies for persons at-risk for BD. Methods and Results Early-BipoLife is a prospective-longitudinal cohort study of 1419 participants (aged 15-35 years) with at least five waves of assessment over a period of at least 2 years (baseline, 6, 12, 18 and 24 months). A research consortium of ten university and teaching hospitals across Germany conducts this study. The following risk groups (RGs) were recruited: RG I: help-seeking youth & young adults consulting early recognition centres/facilities presenting ≥1 of the proposed risk factors for BD, RG II: in-/outpatients with unipolar depressive syndrome, and RG III: in-/ outpatients with attention-deficit/hyperactivity disorder (ADHD). The reference cohort was selected from the German representative IMAGEN cohort. Over the study period, the natural course of risk and resilience factors, early symptoms of BD and changes of symptom severity (including conversion to manifest BD) are observed. Psychometric properties of recently developed, structured instruments on potential risk factors for conversion to BD and subsyndromal symptomatology (Bipolar Prodrome Symptom Scale, Bipolar at-risk criteria, EPI bipolar ) and biomarkers that potentially improve prediction are investigated. Moreover, actual treatment recommendations are monitored in the participating specialized services and compared to recently postulated clinical categorization and treatment guidance in the field of early BD. Conclusion Findings from this study will contribute to an improved knowledge about the natural course of BD, from the onset of first noticeable symptoms (precursors) to fully developed BD, and about mechanisms of conversion from subthreshold to manifest BD. Moreover, these generated data will provide information for the development of evidence-based guidelines for early-targeted detection and preventive intervention for people at risk for BD.

During the acellular pertussis vaccine trial in Sweden, 4 children who were randomly assigned to receive the vaccine died of suspected or confirmed bacterial infections compared to 1 expected. There were no deaths in the placebo arm. This raised concern about the role of pertussis immunization in the development of serious infections. Through linking computerized immunization records with an active surveillance system for serious bacterial infections in children, the authors studied a cohort of 64 591 children immunized through Tennessee county health clinics who had a total of 158 episodes of invasive bacterial infections after a diphtheria and tetanus toxoids and pertussis (DTP) immunization. There were 8 invasive bacterial infections that occurred within the first 7 days following DTP immunization,yielding an age-adjusted relative risk (95% confidence interval) of 1.0 (0.5 to 2.0), compared to the interval 29 or more days following immunization. There were 7 and 20 infections in the 8- through 14- and 15-through 28-day intervals following DTP immunization, giving relative risks of 0.8 (0.4 to 1.7) and 1.2 (0.7 to 1.9), respectively. These data provide reassurance that the use of DTP vaccine is not followed by a large increased risk of serious bacterial infections.

Abstract Background The disease itself as well as immunomodulatory and biological therapy are risk factors for invasive bacterial infections in patients with inflammatory bowel disease (IBD). However, there are limited data on risk factors for bacteraemia in the general population of hospitalised patients with inflammatory bowel disease. The aim of the study was to assess the rate of bacteraemia in hospitalised patients with Inflammatory Bowel Disease and risk factors. Methods An observational cohort of hospitalised patients with Inflammatory Bowel Disease, aged 23–65 years, from 2017 to 2019 in a large tertiary hospital localised in Rzeszow (south-eastern Poland). Patients with one or more positive blood culture were reviewed. Those with Carlson comorbidity index of 2 or greater were excluded. Basic descriptive statistic and logistic regression to evaluate risk factors for bacteraemia were used. Results Of 727 admitted patients, only 1.24% had bacteraemia (9/727) (8, Crohn’s Disease; 1, Ulcerative Colitis). The most common pathogens were Staphylococcus epidermidis (MRCNS - methicillin-resistant coagulase-negative Staphylococcus - strain resistant to all beta-lactam antibiotics: penicillins, penicillins with a B-lactamase inhibitor, cephalosporin and carbapenem) (4/9 patients) and Escherichia coli (3/9 patients). The mortality rate at 30 days of patients with bacteraemia was 0% (no deaths in IBD patients with bacteraemia observed). Longer hospitalisation (mean length of stay for patients with CD was 42 ± 33 vs. 7.95 ± 17.3, p &lt;0.001; mean length of stay for a patient with UC 15 ± 23 vs. 6.25 ± 15.4, p = 0.004) was associated with an increased risk of bacteraemia. Older age was not associated with an increased risk of bacteraemia (P&gt;0.05). In multivariate analysis, treatment with either anti-tumour necrosis factor α, purine analogues, steroids or amino salicylates was not associated with an increased risk of bacteraemia. Conclusion Prolonged hospitalisation, but not Inflammatory Bowel Disease-related treatment, is associated with an increased risk of bacteraemia in hospitalised patients with Inflammatory Bowel Disease.

Abstract Background The high case fatality rate of influenza A(H7N9)-infected patients has been a major clinical concern. Methods To identify the common causes of death due to H7N9 as well as identify risk factors associated with the high inpatient mortality, we retrospectively collected clinical treatment information from 350 hospitalized human cases of H7N9 virus in mainland China during 2013–2017, of which 109 (31.1%) had died, and systematically analyzed the patients’ clinical characteristics and risk factors for death. Results The median age at time of infection was 57 years, whereas the median age at time of death was 61 years, significantly older than those who survived. In contrast to previous studies, we found nosocomial infections comprising Acinetobacter baumannii and Klebsiella most commonly associated with secondary bacterial infections, which was likely due to the high utilization of supportive therapies, including mechanical ventilation (52.6%), extracorporeal membrane oxygenation (14%), continuous renal replacement therapy (19.1%), and artificial liver therapy (9.7%). Age, time from illness onset to antiviral therapy initiation, and secondary bacterial infection were independent risk factors for death. Age &gt;65 years, secondary bacterial infections, and initiation of neuraminidase-inhibitor therapy after 5 days from symptom onset were associated with increased risk of death. Conclusions Death among H7N9 virus–infected patients occurred rapidly after hospital admission, especially among older patients, followed by severe hypoxemia and multisystem organ failure. Our results show that early neuraminidase-inhibitor therapy and reduction of secondary bacterial infections can help reduce mortality. Characterization of 350 hospitalized avian influenza A(H7N9)-infected patients in China shows that age &gt;65 years, secondary bacterial infections, and initiation of neuraminidase-inhibitor therapy after 5 days from symptom onset were associated with increased risk of death.

Abstract The involvement of specific viral and bacterial infections as risk factors for multiple sclerosis has been studied extensively. However, whether this extends to infections in a broader sense is less clear and little is known about whether risk of a multiple sclerosis diagnosis is associated with other types and sites of infections, such as of the CNS. This study aims to assess if hospital-diagnosed infections by type and site before age 20 years are associated with risk of a subsequent multiple sclerosis diagnosis and whether this association is explained entirely by infectious mononucleosis, pneumonia, and CNS infections. Individuals born in Sweden between 1970–1994 were identified using the Swedish Total Population Register (n = 2,422,969). Multiple sclerosis diagnoses from age 20 years and hospital-diagnosed infections before age 20 years were identified using the Swedish National Patient Register. Risk of a multiple sclerosis diagnosis associated with various infections in adolescence (11–19 years) and earlier childhood (birth-10 years) was estimated using Cox regression, with adjustment for sex, parental socioeconomic position, and infection type. None of the infections by age 10 years were associated with risk of a multiple sclerosis diagnosis. Any infection in adolescence increased the risk of a multiple sclerosis diagnosis (hazard ratio 1.33, 95% confidence interval 1.21–1.46) and remained statistically significant after exclusion of infectious mononucleosis, pneumonia, and CNS infection (hazard ratio 1.17, 95% confidence interval 1.06–1.30). CNS infection in adolescence (excluding encephalomyelitis to avoid including acute disseminated encephalitis) increased the risk of a multiple sclerosis diagnosis (hazard ratio 1.85, 95% confidence interval 1.11–3.07). The increased risk of a multiple sclerosis diagnosis associated with viral infection in adolescence was largely explained by infectious mononucleosis. Bacterial infections in adolescence increased risk of a multiple sclerosis diagnosis, but the magnitude of risk reduced after excluding infectious mononucleosis, pneumonia and CNS infection (hazard ratio 1.31, 95% confidence interval 1.13–1.51). Respiratory infection in adolescence also increased risk of a multiple sclerosis diagnosis (hazard ratio 1.51, 95% confidence interval 1.30–1.75), but was not statistically significant after excluding infectious mononucleosis and pneumonia. These findings suggest that a variety of serious infections in adolescence, including novel evidence for CNS infections, are risk factors for a subsequent multiple sclerosis diagnosis, further demonstrating adolescence is a critical period of susceptibility to environmental exposures that raise the risk of a multiple sclerosis diagnosis. Importantly, this increased risk cannot be entirely explained by infectious mononucleosis, pneumonia, or CNS infections.

Background: Temporomandibular joint osteoarthritis (TMJ OA) is a degenerative joint disease. The aim of this review was to present the general characteristics of orally administered nonsteroidal anti-inflammatory drugs (NSAIDs) and to present the efficacy of NSAIDs in the treatment of TMJ OA. Methods: PubMed database was analyzed with the keywords: “(temporomandibular joint) AND ((disorders) OR (osteoarthritis) AND (treatment)) AND (nonsteroidal anti-inflammatory drug)”. After screening of 180 results, 6 studies have been included in this narrative review. Results and Conclusions: Nonsteroidal anti-inflammatory drugs are one of the most commonly used drugs for alleviation of pain localized in the orofacial area. The majority of articles predominantly examined and described diclofenac sodium in the treatment of pain in the course of TMJ OA. Because of the limited number of randomized studies evaluating the efficacy of NSAIDs in the treatment of TMJ OA, as well as high heterogeneity of published researches, it seems impossible to draw up unequivocal recommendations for the usage of NSAIDs in the treatment of TMJ OA. However, it is highly recommended to use the lowest effective dose of NSAIDs for the shortest possible time. Moreover, in patients with increased risk of gastrointestinal complications, supplementary gastroprotective agents should be prescribed.

The global burden of pulmonary tuberculosis (TB) remains a major public health problem that is particularly severe among and disproportionately affects indigenous populations. We aimed to investigate whether genetic factors related to indigeneity affect TB progression risk in a cohort of admixed Peruvians with active TB and their latently infected household contacts. Our results show that Native Peruvian ancestry is positively associated with TB progression risk: a 10% increase in native ancestry tracks with a 25% increased risk of TB progression. This risk is independent of the potentially confounding socio-demographic and environmental factors that we tested here. Our results demonstrate that the genetic contribution to TB risk varies among populations and brings new insight to the long-standing debate on the role of genetic ancestry in susceptibility to TB. Additionally, our study highlights the value of including diverse populations in genetic studies of infectious diseases and other complex phenotypes, and provides a road map for future similar studies where it is important to account for confounding non-genetic risk factors to identify genetic risk factors.

AbstractIt is estimated that erectile dysfunction (ED) affects more than 150 million people worldwide and this number is expected to double by the year 2025. Vascular component represents the most important etiological cause of erectile dysfunction. ED shares almost all risk factors, such as hypertension, diabetes mellitus, hyperlipidaemia and smoking, with arteriosclerosis. Moderate to severe ED is associated with a considerably increased risk for coronary heart disease (CHD). This review was conducted in May 2016, when the PubMed database was searched using the combination of the terms “erectile dysfunction” and “cardiovascular diseases”, “coronary artery diseases” and “risk factors”. In this review, we analyzed the published literature, regarding the predictive role of ED in CVD and the association of ED risk factors with CVD risk factors, aiming to draw particular attention on the role of sexual inquiry of all men to prevent or decrease major cardiovascular events. In conclusion, the early detection of ED can prevent major cardiovascular events with early management of cardiovascular risk and permits to include patients in a risk stratification group. Erectile function should be evaluated using questionnaires in all male patients to prevent and decrease the rates of major cardiovascular events.
