IRF2BP2 mutation with autoimmune enteropathy, immune deficiency, and respiratory failure

Case history: We present the case of a 31-year-old Hispanic male with history of recurrent bronchiectasis, invasive aspergillosis, and severe persistent asthma, who is now status post lung transplant for end-stage lung disease. He initially presented at 7 years of age with diarrhea, failure to thrive, and nearly absent immunoglobulin levels (IgG < 33 mg/dL, IgA < 7 mg/dL, IgM = 11 mg/dL, IgE = 4 IU/dL) necessitating IVIG treatment. Small intestinal biopsy showed villous atrophy consistent with autoimmune enteropathy. Sweat chloride was reported as indeterminate (44 me/dL). Initial WBC, platelet, and T- and NK-cell counts were within normal range, and B-cell count and percentage were borderline low. Most recently, he was found to have increased immature B-cell count (CD21low), decreased memory B-cells, and poor pneumococcal vaccine antibody response. Patient has been hospitalized numerous times with increasingly severe bronchiectasis, pneumonitis, and COVID-19 infections twice despite vaccination, leading to respiratory failure and lung transplantation. Family history is negative for immune deficiency and lung diseases. Discussion(s): Of these 3 VUSs (see the table), the one in IRF2BP2 has the most pathogenic potential due to its autosomal dominant inheritance, its location in a conserved domain (Ring), and previous case reports of pathogenic variants at the same or adjacent alleles 1-3. Baxter et al reported a de novo truncating mutation in IRF2BP2 at codon 536 (c.1606CinsTTT), which is similar to our patient's mutation. This patient was noted to have an IPEX-like presentation, with chronic diarrhea, hypogammaglobulinemia, and recurrent infections. Variant Functional Prediction Score for our variant predicts a potentially high damage effect. There are 2 other case reports of heterozygous mutations in loci adjacent to this allele;one (c.1652G>A)2 with a similar clinical phenotype to our patient and the other (C.625-665 del)3 with primarily inflammatory features and few infections. Impact: This case highlights a variant in IRF2BP2 associated with severe hypogammaglobulinemia, recurrent pulmonary infections, and autoimmune enteropathy.

Uptake of vaccination in older Indian patients with cancer: A cross-sectional observational study

Background: Older patients with cancer are at a higher risk of invasive infections. Vaccination is an effective approach to decrease the mortality and morbidity associated with infections. Objective(s): Our primary objective was to evaluate the proportion of older patients with cancer who had received routine vaccinations against pneumococcal, influenza, and coronavirus disease 2019 (COVID-19). Our secondary objective was to identify the factors associated with vaccine uptake such as age, sex, education, marital status, comorbidities, and place of residence. Material(s) and Method(s): This cross-sectional observational study was conducted in the geriatric oncology outpatient clinic of the Department of Medical Oncology at the Tata Memorial Hospital, a tertiary care cancer hospital in Mumbai, India, from February 2020 to January 2023. We included all patients aged >=60 years who were evaluated in the geriatric oncology clinic during the study period and for whom the immunization details were available. The uptake of COVID-19 vaccine was calculated from March 2021 onwards, which was when the COVID-19 vaccine became available to patients aged >=60 years in India. Result(s): We enrolled 1762 patients;1342 (76.2%) were male. The mean age was 68.4 (SD, 5.8) years;795 (45%) patients were from the west zone of India. Only 12 (0.68%) patients had received the pneumococcal vaccine, and 13 (0.7%) had received the influenza vaccine. At least one dose of the COVID-19 vaccine had been taken by 1302 of 1562 patients (83.3%). On univariate logistic regression, education, marital status, geographic zone of residence, and primary tumor site were correlated with the uptake of COVID-19 vaccine. Factors associated with a greater COVID-19 vaccine uptake included education (up to Std 10 and higher vs. less than Std 10: Odds Ratio [OR], 1.46;95% confidence interval [CI], 1.07-1.99;P = 0.018, and illiterate vs. less than Std 10: OR, 0.70;95% CI, 0.50-0.99;P = 0.041), marital status (unmarried vs. married: OR, 0.27;95% CI, 0.08-1.08;P = 0.046, and widow/widower vs. married: OR, 0.67;95% CI, 0.48-0.94;P = 0.017), lung and gastrointestinal vs. head-and-neck primary tumors (lung cancer vs. head-and-neck cancer: OR, 1.60;95% CI, 1.02-2.47;P = 0.038, and gastrointestinal vs.head-and-neck cancer: OR, 2.18;95% CI, 1.37-3.42;P < 0.001), and place of residence (west zone vs. central India: OR, 0.34;95% CI, 0.13-0.75;P = 0.015). Conclusion(s): Fewer than 1 in 100 older Indian patients with cancer receive routine immunization with influenza and pneumococcal vaccines. Hearteningly, the uptake of COVID-19 vaccination in older Indian patients with cancer is over 80%, possibly due to the global recognition of its importance during the pandemic. Similar measures as those used to increase the uptake of COVID-19 vaccines during the pandemic may be beneficial to increase the uptake of routine vaccinations.Copyright © 2023 Cancer Research, Statistics, and Treatment.

Vaccination status of the adult sickle cell anaemia population: The South Wales experience

The Sickle Cell Society have issued standards for additional immunisations that adults with sickle cell disease (SCD) require. These include annual influenza, 5-yearly pneumococcal conjugate vaccine (PPV23) and Hepatitis B vaccination. Patients who have not received their primary vaccination as part of the national schedule in the UK should also receive further additional vaccines. We reviewed whether adults with SCD in South Wales currently receive these. 49 adult patients were identified as having SCD under the care of the Hereditary Anaemia Service based in the University Hospital of Wales, Cardiff. GP records were not available for 5 patients leaving a final cohort of 44 patients to analyse. Average age was 33 years (range 17-67). Median age was 27 with the cohort predominantly lying in the 17-29 year category (52%). Results showed good compliance with the annual influenza vaccine in those over 40 (>80%). However, compliance for the 17-29 category and 30-39 categories were 37.5% and 42.8%, respectively. The improved compliance in those >40 was not seen with the 5-yearly pneumococcal vaccine. Compliance was worse in all age groups compared to the annual flu vaccine with only 23% compliance overall. However, when looking at those who had received a single dose of PPV23, the numbers improved to nearly 60%. Compliance with the SARS-CoV2 vaccination was highest at 61.3%. However, rates were lower in the 17-29 and 30-39 age groups in keeping with previous trends. Only 34.1% of patients had full hepatitis B cover. Again, trends in compliance mirrored previous with poorer rates in those under 40. Assessing compliance for the remainder of the standards was more challenging given that we could not confirm retrospectively how many of our cohort had received their primary vaccinations in other parts of the UK, thought to be around half. However, most of the cohort had not received any additional vaccines suggesting high non-compliance regardless. This review looked at data from 2020 and likely reflects the impact of the SARS-CoV2, whether positive or negative. The reduced compliance in 5-yearly pneumococcal compared to flu suggest better health-professional education is needed;if patients are attending for their annual flu vaccine, there is ample opportunity to administer other vaccines. The vaccination rate for our patient group is comparable to national rates by ethnicity although lower than the national average for age. Vaccination rates for the SCD population of South Wales are not adequate. Better education and engagement is needed.

Retrospective review of vaccination status in patients with newly diagnosed chronic lymphocytic leukaemia

Introduction: Patients with chronic lymphocytic leukaemia (CLL) are at increased risk of infection. CLL is associated with a secondary immunodeficiency and impaired response to vaccination. Recent British Society of Haematology guidelines recommend that patients with CLL should receive vaccination against pneumococcal infection at diagnosis, an annual influenza vaccine and COVID-19 vaccination. Patients aged 70-79 years should also receive the Shingrix vaccine. Patients with CLL should not receive live vaccines. In response to this guideline, a letter detailing vaccination requirements was created for patients to give to their general practitioner (GP). The local process for vaccination referral has since changed. Previously, vaccination requirements were communicated to the GP via letter. There is now a dedicated Vaccination Hub to which clinicians can directly refer patients for appropriate vaccinations. Aim(s): The aim of this project was to assess vaccination referral and vaccination status in patients with newly diagnosed CLL. Method(s): All new diagnoses of CLL from 2021 to 2022 were identified by review of the Haematology Multi-Disciplinary Team meeting electronic registration forms. Electronic patient records were reviewed to determine vaccination referral completion and vaccination status. Result(s): A total of 29 patients were identified as new diagnoses of CLL. Seventeen patients were diagnosed in 2021 and 12 in 2022. Sixty-nine percent of the patients were male and the average age was 70.9 years. Vaccination was discussed with 11 patients (38%) and 10 patients (34%) were referred for vaccination. Eleven patients (38%) had never received a pneumococcal vaccine. Nine patients (31%) had previously received the vaccine but not within the past 5 years. Five patients (17%) patients had received one dose of Pneumovax 23 following referral. No patients had received the initial Prevenar 13 vaccine. Twelve patients (41%) had not received an influenza vaccine. Of those who had received the vaccine, the majority (70%) had received this routinely. Similarly, 71% of patients had received the COVID-19 vaccine routinely as opposed to three patients who received this postreferral. Of those who were eligible, 50% had received the Shingrix vaccine. Conclusion/Discussion: Local rates of vaccination in patients with CLL are low. Numbers were too small to allow for comparison between the methods of referral. Of those referred, not all received the appropriate vaccinations. Further work is therefore required to improve both the number and completion of the referrals. Future steps will include local teaching on vaccinations in CLL and the referral pathway.

Effects of pneumococcal conjugate vaccines on reducing the risk of respiratory disease associated with coronavirus infection.

Pneumococcal conjugate vaccines (PCVs) provide protection against vaccine-type pneumococcal disease in both children and adults. Growing evidence suggests that PCVs also reduce pneumonia and lower respiratory tract infections (LRTIs) more broadly, including protecting against viral-associated respiratory diseases. In this short narrative review, we highlight clinical studies investigating whether PCVs might have a role in reducing coronavirus disease, both those caused by endemic human coronaviruses (HCoVs) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). These studies include two randomized controlled trials assessing HCoV-associated pneumonia, one each in children and older adults, and two observational studies of PCV13 effectiveness against HCoV-associated LRTI and COVID-19 in adults. We discuss possible mechanisms for PCV protection including preventing viral pneumococcal co-infections and the possibility that pneumococci in the upper respiratory tract might modify the host immune response to SARS-CoV-2. Lastly, we identify knowledge gaps and further questions on the potential role of PCVs during the COVID-19 pandemic.

National calendar of preventive vaccinations: present and future

In the context of a pandemic of a new coronavirus infection, vaccine prophylaxis within the framework of the National Calendar of Preventive Vaccinations (NCPV) is an absolute priority in the fight against infectious diseases. The lecture presents the structure and features of the NCPV, the main directions of its improvement, information on the priority infections for vaccination. The strategy of immunization throughout life, which guarantees the creation of maximum protection against infections and preservation of the optimal level of health of people without age restrictions, is considered. Information is provided on approaches to vaccination of various patient populations against new coronavirus, pertussis, pneumococcal, and rotavirus infections. The presented lecture materials can be useful both to medical students and doctors of various specialties (infectious disease specialists, pediatricians, epidemiologists, bacteriologists).Copyright © 2022 by the authors.

Organ transplantation and vaccination

Organ transplant recipients are at a high risk of infection with high hospitalization rate, critical rate and fatality, due to low immune function caused by taking immunosuppressants for a period of long time after organ transplantation. Currently, vaccination is recognized as an effective approach to prevent infection. Organ transplant recipients may be vaccinated according to individual conditions. However, the sensitivity to vaccines may decline in organ transplant recipients. The types, methods and timing of vaccination have constantly been the hot spots of clinical trials. In this article, the general principles, specific vaccines and SARS-CoV-2 vaccines of vaccination in organ transplant recipients were briefly reviewed, aiming to provide reference for the vaccination of organ transplant recipients. Moreover, current status of SARS-CoV-2 vaccination for organ transplant recipients was illustrated under the global outbreak of novel coronavirus pneumonia pandemic.Copyright © 2022 Journal of Zhongshan University.

An audit of uptake of flu, COVID-19 and pneumococcal vaccines in a cohort of people living with HIV

Background: People living with HIV are at greater risk of complications associated with influenza, SARS-CoV-2 and pneumococcus than the general population and BHIVA guidelines recommend vaccinating all patients against these infections. The purpose of this audit was to determine the uptake of these vaccines, and factors associated with uptake, to inform vaccine delivery models. Method(s): All patients who received HIV care in our service at the end of November 2022 were included. Demographic data were collected from the service database, clinical data and pneumococcal vaccine (Prevenar-13) status were obtained from clinical records and COVID-19 and flu vaccine (2021) uptake was obtained from the Vaccine Management Tool (VMT). At the time of audit all patients were recommended to have received at least 3 doses of a SARS-CoV-2 vaccine. Caldicott approval was received for this work. Result(s): There were 364 patients known to the service of which one was excluded as clinical information was not available. Sixty-seven percent had received flu vaccine, 88% >= one dose of COVID-19 vaccination, 76% at least 3 doses of COVID-19 vaccination and 88% had received Prevenar-13. Three percent had received no vaccines and 60% had completed all vaccines. Uptake of both flu and COVID-19 vaccines were lower in the following groups: <50 years old (51% and 62% respectively), urban residence (65%, 71%), higher deprivation scores (51-65%, 64-75%) less time in HIV care (57%, 70%), those not on ART (13%, 25%), CD4 <200 cells/mm3 (40%, 50%), detectable viral load (33%, 42%), those out of care (23%, 23%) and those known to the harm reduction service (33%, 33%). There was higher uptake of Prevenar-13 in all groups. Uptake of all vaccines was high in those with comorbidities. Conclusion(s): The high uptake of Prevenar-13 in higher risk groups suggests that the model of vaccine delivery, opportunistic and pro-active recall for inhouse vaccination, is more effective for protecting those at highest risk for poor outcomes and for those for whom access is challenging compared to the centralised national recall system at designated Vaccine hubs. Vaccination resourcing, planning and delivery should consider the needs of specific risk groups to ensure best outcomes.

Vaccination in Patients with Inflammatory Rheumatic Diseases: Preliminary Results of an International, Real-World Life Panlar's Register

Objectives: To evaluate vaccination among patients with inflammatory rheumatic diseases initiating disease-modifying antirheumatic drugs (DMARD) Methods: Data from the real-world life PANLAR's register of consecutive patients diagnosed with RA, PsA, and axSpa (2010 ACR-EULAR /2006 CASPAR-2009 ASAS) from Dec 2021 to Dec 2022 were analyzed. Prevalence of recommended vaccinations were compared between different inflammatory rheumatic diseases. Categorical variables were expressed as %. Tables were analyzed with chi2 or Fisher tests, continuous variables (median, IQR)with the Kruskal-Wallis test, according with the variables type. A p value <=0.05 was considered significant. Result(s): 608 patients were included. Among patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial Spondyloarthritis (axSpA) are presented in the table. RA and axSpA seemed to have lower vaccination rate of pneumococcal vaccines than PsA. (p = 0.045 for conjugate anti pneumococcal vaccine in RA vs PsA). A large percentage of the population was vaccinated against COVID-19. There was a high rate of influenza vaccination in all three diseases. Conclusion(s): In Latin America, anti-pneumococcal vaccination is low, especially in patients with RA and axSpA. For other vaccines there was an acceptable level of vaccination without differences between diseases.

To the 100th Anniversary of the Birth of Academician V.A. Nasonova. Infections and Rheumatic Diseases: From the Past to the Future

In rheumatology, the problem of infectious pathology is quite acute. This is primarily due to the participation of various infectious agents in the development of immuno-inflammatory rheumatic diseases (IIRD), in which microorganisms play a trigger role, triggering the immunopathological mechanisms of inflammation. Vivid examples of such diseases are acute rheumatic fever and reactive arthritis. The infectious etiology of Lyme disease has been proven. An equally difficult task is the fight against comorbid infection (CI), which often complicates the course of many IIRD due to a violation of the immune status caused by both the background disease and the use of immunosuppressive drugs. The predominance of respiratory tract lesions in the structure of CI in patients with IIRD makes it necessary to use influenza and pneumococcal vaccines in them, since the risk of deaths from these infections among these patients is quite high. During the development of the COVID-19 pandemic, which has become a challenge to all mankind, a large number of new fundamental and medical problems have been revealed concerning the relationship between viral infection and many widespread chronic non-communicable diseases, among which IIRDs occupy an important position. As one of the methods of combating the current COVID-19 pandemic, great hopes are pinned on the widespread use of vaccination. The possibility of using monoclonal antibodies for pre-exposure prophylaxis of COVID-19, including in patients with IIRD, is discussed.Copyright © 2023 Ima-Press Publishing House.

Clinical Approaches to Minimize Readmissions of Patients with COPD: A Narrative Review

Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease and also a lead-ing cause of morbidity and mortality worldwide. The frequent readmissions of patients with COPD may reduce lung function, mental health, and quality of life;it also increases the cost of treatment and mortality rate. Some common factors that may increase the readmission frequency of COPD patients include delay of diagnosis, advanced lung function decline, lack of adherence for COPD treatment, ineffective management of comorbidities, acute exacerbation or stable COPD, and infec-tions. However, these factors might be well controlled with appropriate approaches to minimize the readmission of patients with COPD. In this review, we propose a strategy with a seven-step approach to reduce the readmission in COPD patients, including early diagnosis of COPD, optimal treatment for stable COPD, targeted management of comorbidities, adequate therapy for acute ex-acerbations, individualized action plans for COPD patients, effective prevention of bacterial and viral infections, and adaptive program of pulmonary rehabilitation. Thus, implementing this approach may reduce the risk of readmission in patients with COPD.Copyright © 2023 Bentham Science Publishers.

Persistence of Pneumococcal Carriage among Older Adults in the Community despite COVID-19 Mitigation Measures.

Reported rates of invasive pneumococcal disease were markedly lower than normal during the 2020/2021 winter in the Northern Hemisphere, the first year after the start of the COVID-19 pandemic. However, little is known about rates of carriage of pneumococcus among adults during this period. Between October 2020-August 2021, couples in the Greater New Haven Area, USA, were enrolled if both individuals were aged 60 years and above and did not have any individuals under the age of 60 years living in the household. Saliva samples and questionnaires regarding social activities and contacts and medical history were obtained every 2 weeks for a period of 10 weeks. Following culture-enrichment, extracted DNA was tested using qPCR for pneumococcus-specific sequences piaB and lytA. Individuals were considered positive for pneumococcal carriage when Ct values for piaB were ≤40. Results. We collected 567 saliva samples from 95 individuals (47 household pairs and 1 singleton). Of those, 7.1% of samples tested positive for pneumococcus, representing 22/95 (23.2%) individuals and 16/48 (33.3%) households. Study participants attended few social events during this period. However, many participants continued to have regular contact with children. Individuals who had regular contact with preschool and school-aged children (i.e., 2 to 9 year olds) had a higher prevalence of carriage (15.9% versus 5.4%). Despite COVID-19-related disruptions, a large proportion of older adults continued to carry pneumococcus. Prevalence was particularly high among those who had contact with school-aged children, but carriage was not limited to this group. IMPORTANCE Carriage of Streptococcus pneumoniae (pneumococcus) in the upper respiratory tract is considered a prerequisite to invasive pneumococcal disease. During the first year of the COVID-19 pandemic, markedly lower rates of invasive pneumococcal disease were reported worldwide. Despite this, by testing saliva samples with PCR, we found that older adults continued to carry pneumococcus at pre-pandemic levels. Importantly, this study was conducted during a period when transmission mitigation measures related to the COVID-19 pandemic were in place. However, our observations are in line with reports from Israel and Belgium where carriage was also found to persist in children. In line with this, we observed that carriage prevalence was particularly high among the older adults in our study who maintained contact with school-aged children.

An audit to review the uptake of recommended vaccinations in patients with psoriasis prescribed immunosuppressing medications

Previous reports of vaccination uptake rates in dermatology patients are variable. The aim of this audit was to get an upto-date assessment from those attending our service. Future vaccination uptake rates and awareness are likely to be affected by the COVID-19 pandemic. This is one of the last and largest studies of this topic in the pre-COVID-19 era. Patients with psoriasis receiving immunosuppressants are at increased risk of developing infections, primarily respiratory tract infections. Published guidelines recommend that this cohort of patients receive both the influenza and pneumococcal (PPV23) vaccines. We conducted a survey of patients on systemic immunosuppressive medication for their skin disease attending our dermatology department. An audit was completed in August 2019 with a subsequent reaudit in February 2020. An intervention of advertising, staff education and vaccine promotion to patients during consultations was implemented between audits. The study was approved by the hospital audit review board. A total of 104 patients were recorded in August, with 98 recorded in February. Overall, the uptake of the influenza vaccine was 77% and 78% in the respective audits. There was an increase from 63% to 72% in the uptake of the PPV23 vaccine. Those receiving biological medications had a higher uptake of vaccinations than those receiving traditional systemic agents such as methotrexate (approximately 80% vs. 70% for influenza and 62% vs. 70% PPV23 in the respective audits). Over 95% of patients self-reported that they had been advised to acquire vaccinations by the dermatology team. This audit shows that vaccination rates are already high in this cohort of patients, supporting best practice in our centre. There is a tendency to be more compliant with recommendations if receiving a biological agent. There was a small but noticeable increase in uptake after our interventions. A similar French study showed a much lower uptake rate of 3- 25% {Bonhomme A, Freling E, Reigneau M et al. [Vaccination status in psoriasis patients on immunosuppressant therapy (including biologics)]. Ann Dermatol Venereol 2017;144: 92-9 (in French)}. This audit represents one of the largest studies of this topic in dermatology patients.

Patients with COVID-19 versus non-COVID-19 community-acquired pneumonia

Background: SARS-CoV-2 has emerged as a novel pathogen of community-acquired pneumonia (CAP). Aims and objectives: We aimed to compare characteristics, clinical outcomes and pneumococcal identification in patients with COVID-19 vs non-COVID-19 CAP. Method(s): EGNATIA is an ongoing, prospective study of adults >=19yo hospitalized with clinical and radiographicallyconfirmed CAP in Greece. The primary objective is to estimate the proportion of CAP due to pneumococcal serotypes included in 13-valent pneumococcal conjugate vaccine (PCV13). Pneumococcus was identified using serotype-specific urinary antigen detection assays (UAD 1/2), BinaxNow and conventional cultures. Testing for SARS-CoV-2 was performed as per national guidelines. Result(s): We compared 202 patients with COVID-19 pneumonia during Apr2020-Mar2021 vs 1033 patients with nonCOVID-19 CAP during Nov2017-Oct2020. Patients with COVID-19 were younger (median age 68.8 vs 75.8 years) and had fewer comorbidities (67.8% with >=1 underlying condition vs 79.2%) than non-COVID-19 patients. Patients with COVID-19 less frequently reported past pneumonia episodes (0.5% vs 7.7%) but were more frequently nursing home residents (13.9% vs 6%). Patients with COVID-19 had less severe pneumonia presentation (CURB 65 3-5 6.4% vs 30.5%;PSI IV-V 41.1% vs 55.2%) but required mechanical ventilation more frequently (7.4% vs 1.9%) and had a longer hospital stay (mean 17.4 vs 9.6 days). In-hospital mortality was similar between the 2 groups (7.9% in COVID-19 vs 8.9% in non-COVID-19). Pneumococcus was identified less frequently in patients with COVID-19 vs non-COVID-19 CAP (4% vs 11.1%). Conclusion(s): Significant differences were identified in patients with COVID-19 vs non-COVID-19 CAP.

Adult Vaccination

Adult vaccination rates are low in the United States, despite clear benefits for reducing morbidity and mortality. Vaccine science is evolving rapidly, and family physicians must maintain familiarity with the most recent guidelines. The recommended adult immunization schedule is updated annually by the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention. All eligible patients should receive SARS-CoV-2 vaccines according to the current guidelines. Adults without contraindications should also receive an annual influenza vaccine. Hepatitis A vaccine is recommended for adults with specific risk factors. All pregnant patients, adults younger than 60 years, and those 60 years and older who have risk factors should receive a hepatitis B vaccine. A 15- or 20-valent pneumococcal conjugate vaccine is recommended for all patients who are 65 years and older. Patients who receive 15-valent pneumococcal conjugate vaccine should receive a dose of 23-valent pneumococcal polysaccharide vaccine one year later. Adults 19 to 64 years of age should receive a pneumococcal vaccination if they have medical risk factors. A single dose of measles, mumps, and rubella vaccine is recommended for adults without presumptive immunity, and additional doses are recommended for patients with HIV and postdelivery for pregnant patients who are not immune to rubella. A tetanus and diphtheria toxoids booster is recommended every 10 years. For pregnant patients and those in close contact with young infants, a tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine should be administered. The human papillomavirus vaccine is recommended for all people through 26 years of age. Herpes zoster vaccine is indicated for all adults 50 years and older.Copyright © 2022 American Academy of Family Physicians.

Inflammatory Bowel Disease in the elderly, a survey of elderly patient demographics, diseaserelated complications and compliance with vaccination and screening services

Background: Inflammatory Bowel Disease (IBD) in the elderly (>60yrs) is becoming more prevalent in concordance with the ageing population and the rising incidence of IBD. An increasing number of patients are receiving a diagnosis of IBD in later years in addition to those with known IBD transitioning to elderly. The presentation, disease course, risk of complications and choice of medical therapies differ in this group from younger cohorts. We aimed to examine patient demographics and the incidence of adverse effects/complications amongst elderly IBD patients. We also sought to identify appropriate vaccination rates and uptake with screening services. Method(s): In a single tertiary centre, IBD patients aged >60 attending the outpatient clinic or admitted acutely were invited to complete an anonymous written survey. Result(s): 28 patients surveyed to date. 61% (n=17) had a diagnosis of UC. 54% were female (n=15). Mean age was 67.5, while mean age at diagnosis was 50 (range 19-65). 25% (n=7) received a diagnosis of IBD after 60 years, of which 57% were female. Mean BMI was 25.9. 25% (n=7) reported an infection in the last 6 months, all of whom required treatment with antibiotics. There was only one case of infection requiring hospitilisation, a patient on biologic therapy who developed a clostridium difficile infection. COVID-19 affected 39% (n=11), none required hospitilisation. 21% (n=6) report 2 or more comorbidities, of which 50% report a recent infection requiring treatment. All patients who required IBD surgery (n=5) had a high BMI. 57% (n=16) had a smoking history, with 14% (n=4) being active smokers. Infliximab and salofalk granules were the most prescribed IBD treatments. 46% were on biologics (n=13), with anti-TNF being the most common (29%). 25% (n=7) reported steroid use in the last year while 14% were not currently on IBD treatment. 21.4% (n=6) reported prior malignancy, skin cancer being most common. 50% of cancer sufferers were smokers. 100% have had a minimal of two COVID-19 vaccines. 64% (n=18) have had a flu-vaccine in the last 12 months with 75% (n=21) report annual flu-vaccine uptake. 61% (n=17) had the pneumococcal vaccine. Bowel screening participation was 46.5% (n=13). Conclusion(s): Smoking, high BMI and multiple comorbidities were common in elderly IBD patients. Infections were common in this cohort and typically required treatment with antibiotics, however, were rarely severe or required hospitalisation. Severe infections were seen in those on biologic therapy. Biologics were commonly prescribed to elderly IBD patients. Skin cancer was the most common malignancy. There was suboptimal uptake with vaccinations and bowel screening. (Figure Presented).

Pneumococcal Vaccination is a Challenge of Pediatric Allergists

Objective: An increased risk of invasive pneumococcal disease (IPD) has been reported in children with asthma before the introduction of pneumococcal vaccines (PVs). However, the evidence is limited after PV entered the routine immunization schedule. We aimed to investigate whether pediatric allergists recommend additional PV (aPV) to asthmatic children and if so whether there are any asthma-specific risk factors they consider. We also wanted to determine any changes in their recommendations during the COVID-19 pandemic. Material(s) and Method(s): A questionnaire was e-mailed to all members of the Academy of Pediatric Allergy and Asthma in Turkey. The questionnaire was filled online and consisted of 14 questions. Result(s): The questionnaire was e-mailed to 220 members. The response rate was 56.3% and 60.5% of PA recommended aPV. The most frequent asthma specific factors for aPV were severe asthma (70.2%), long term oral corticosteroid use (65.3%) and frequent exacerbations / hospitalizations (62.9%). COVID-19 pandemic increased the rate of questions asked to PA about aPV for asthmatic children compared to previous periods (75.8 vs 33.9%) (p<0.001) and %27 of PA changed their recommendations in favor of aPV during pandemic. Conclusion(s): Asthmatic children is not infrequent. Severe asthma and related factors seem to be the leading reasons to recommend aPV for asthmatic children. The aPV recommendation by PA is increased during COVID-19 pandemic.Copyright © 2022 Bilimsel Tip Yayinevi. All rights reserved.

Drug Repositioning as a Therapeutic Strategy against Streptococcus pneumoniae: Cell Membrane as Potential Target.

A collection of repurposing drugs (Prestwick Chemical Library) containing 1200 compounds was screened to investigate the drugs' antimicrobial effects against planktonic cultures of the respiratory pathogen Streptococcus pneumoniae. After four discrimination rounds, a set of seven compounds was finally selected, namely (i) clofilium tosylate; (ii) vanoxerine; (iii) mitoxantrone dihydrochloride; (iv) amiodarone hydrochloride; (v) tamoxifen citrate; (vi) terfenadine; and (vii) clomiphene citrate (Z, E). These molecules arrested pneumococcal growth in a liquid medium and induced a decrease in bacterial viability between 90.0% and 99.9% at 25 µM concentration, with minimal inhibitory concentrations (MICs) also in the micromolar range. Moreover, all compounds but mitoxantrone caused a remarkable increase in the permeability of the bacterial membrane and share a common, minimal chemical structure consisting of an aliphatic amine linked to a phenyl moiety via a short carbon/oxygen linker. These results open new possibilities to tackle pneumococcal disease through drug repositioning and provide clues for the design of novel membrane-targeted antimicrobials with a related chemical structure.
