Abstract
In South Africa, basic healthcare centres treat sexually transmitted infections (STIs) using a syndromic approach. In line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, a complete study of all randomised controlled trials and surveillance data relevant to N. gonorrhoeae antibiotic resistance was conducted. To discover papers published between 2002 and 2022, searches were undertaken using PubMed, EMBASE and any other relevant databases. This systematic review extracted a total of 463 articles published between 2002 and 2022 from a variety of online research sources. Seven South African provinces were represented in the studies that were assessed. Mpumalanga and the North West Province did not have any studies that described the identification and monitoring of antimicrobial resistance (AMR). This study presents data obtained from a comprehensive analysis of 2140 isolates, in which we examined the presence of one or more antibiotic resistance. Our findings revealed that out of these samples, 1891 isolates exhibited antimicrobial properties; tetracycline was the antimicrobial resistance that was found the most often (30%), followed by ciprofloxacin (19%) and penicillin (17%). The mean of the isolates was 143, the upper 95% mean was 243, and the standard deviation (SD) was 181.6. All microbiological identification and susceptibility testing processes must be standardised and improved so national organisations can monitor AMR. The nation's health community must address all identified areas of concern to avoid AMR.

Efficacy and safety of corticosteroids for the treatment of community-acquired pneumonia: A systematic review and meta-analysis of randomized controlled trials. J Crit Care 2024; 80:154507. [PMID: 38128217 DOI: 10.1016/j.jcrc.2023.154507] [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: 08/09/2023] [Revised: 10/01/2023] [Accepted: 10/03/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The role of corticosteroids in the treatment of community-acquired pneumonia (CAP) remains uncertain. We conducted an updated meta-analysis to investigate the effectiveness and potential effect modifiers of adjunctive corticosteroids in patients with CAP. METHODS The protocol of this meta-analysis was registered with PROSPERO (CRD42022354920). We searched MEDLINE, Embase, the Cochrane Library and trial registers from inception till March 2023 to identify randomized controlled trials (RCTs) investigating corticosteroids in adult patients with CAP. Our primary outcome was the risk of all-cause mortality within 30 days after randomization (if not reported at day 30, we extracted the outcome closest to 30 days). Risk ratios (RR) and mean differences (MDs) were pooled under a random-effects model. RESULTS Fifteen RCTs (n = 3252 patients) were included in this review. Corticosteroids reduced the risk of all-cause mortality in CAP patients (RR: 0.69, 95% CI: 0.53-0.89; high certainty). This significant result was restricted to hydrocortisone therapy and patients with severe CAP. Additionally, younger patients demonstrated a greater reduction in mortality. Corticosteroids reduced the incidence of shock and the need for mechanical ventilation (MV), and decreased the length of hospital and ICU stay (moderate certainty). CONCLUSIONS Corticosteroids reduce the risk of all-cause mortality, especially in younger patients receiving hydrocortisone, and probably decrease the need for MV, the incidence of shock, and the length of hospital and ICU stay in patients with CAP. Our findings indicate that patients with CAP, especially severe CAP, will benefit from adjunctive corticosteroid therapy.

Clinical value of glucocorticoids for severe community-acquired pneumonia: A systematic review and meta-analysis based on randomized controlled trials. Medicine (Baltimore) 2023; 102:e36047. [PMID: 37986401 PMCID: PMC10659673 DOI: 10.1097/md.0000000000036047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 10/18/2023] [Accepted: 10/19/2023] [Indexed: 11/22/2023] Open
Abstract
BACKGROUND Severe community-acquired pneumonia (sCAP) is characterized by severe symptoms and a poor prognosis, especially with the recent global impact of novel coronavirus in recent years. The use of glucocorticoids in sCAP is currently a subject of debate. To evaluate the clinical efficacy and safety of glucocorticoids and provide guidance for their rational use in clinical practice, we conducted this study. METHODS We searched PubMed, Web of Science, and China National Knowledge Infrastructure using the following search terms: "pneumonia", "pneumonias", "Pulmonary Inflammation", "Pulmonary Inflammations", "Lung Inflammation", and "Lung Inflammations". The primary outcomes included mortality and the length of hospital stay. The secondary outcomes included the duration of mechanical ventilation, duration of vasoactive drug use, gastrointestinal bleeding, and multiple infections. The Cochrane Collaboration was used to assess the risk of bias of the included studies. Stata/MP14 was used for meta-analysis. RESULTS These studies contained information on 1252 patients who received glucocorticoids and 1280 patients who did not. Meta-analysis showed that there was no difference in terms of mortality [risk ratio (RR) = 0.93, 95% confidence interval (CI): 0.81-1.07, P > .05], gastrointestinal bleeding (RR = 1.38, 95% CI: 0.83-2.30, P < .05), multiple infections (RR = 1.17, 95% CI: 0.90-1.53, P > .05) and length of hospital stay (mean difference [MD] = -0.87, 95% CI: -2.35 to 0.61, P > .05) between the hormonal and nonhormonal groups. However, there was a significant difference in the duration of mechanical ventilation (MD = -1.54; 95% CI, -1.89 to -1.12, P < .05) and the duration of use of vasoactive drugs (MD = -14.09, 95% CI: -15.72 to -12.46, P < .05). CONCLUSION Glucocorticoids reduced the duration of mechanical ventilation duration and vasoactive drug use in sCAP patients without increasing the risk of adverse events including hyperglycemia and multiple infections. However, there was no significant difference in mortality or length of hospital stay in sCAP patients between glucocorticoid and non-glucocorticoid groups. Glucocorticoids could be recommended for patients with sCAP with respiratory failure or hemodynamic instability.

Abstract
BACKGROUND hip fractures commonly have an impact on older adults' health. Surgical treatment aims to reduce pain and promote functional ability. However, developing adverse health outcomes or complications post-hip surgery may impede older patients' recovery to return to functional ability as pre-fracture. We aimed to examine the association of personal factors and adverse health outcomes during hospitalization and post-hospital discharge on the functional ability of older people undergoing hip surgery. METHODS a total of 120 older people with hip fractures who were scheduled for surgery at three tertiary hospitals and met the inclusion criteria were recruited for this study. Data were obtained at admission, before discharge, and during the two-week postoperative follow-up using the Demographic, Hip Dysfunction and Osteoarthritis Outcome Score, Joint Replacement, the Confusion Assessment Method (CAM) Thai version, and Health Outcome Questionnaires. Descriptive statistics and multiple logistic regression analyses were performed to analyze the data. RESULTS most participants were female, with a mean age of 78.10 years (range = 60-93; SD = 8.37). The most common adverse health outcome during hospitalization was urinary tract infection, followed by delirium, pneumonia, deep vein thrombosis, and surgical site infection. At two weeks immediately post-hospital discharge, 16 participants experienced unpleasant events, including delirium, urinary tract infection, surgical site infection, and pneumonia. The significant predictors of poor functional ability at two weeks immediately post-hospital discharge were old age (OR = 1.114, p = 0.001), subtrochanteric fracture (OR = 13.48, p = 0.008), and type of surgery (OR = 4.105, p = 0.049).

Abstract
BACKGROUND Electronic continuous surveillance databases are ideal for monitoring antibiotic use (ABU) in hospitalised patients for antibiotic stewardship programmes (ASP). However, such databases are scarce in low-resource settings. Point prevalence surveys (PPS) are viable alternatives. This report describes ABU and identifies ASP implementation improvement areas in Limpopo Province, South Africa. METHODS This cross-sectional descriptive study extracted patient-level ABU data from patients' files using a modified global PPS tool. Data were collected between September and November 2021 at five regional hospitals in Limpopo Province, South Africa. All patients in the wards before 8 a.m. on study days with an antibiotic prescription were included. Antibiotic use was stratified by Anatomic Therapeutic Chemical and Access, Watch, Reserve classifications and presented as frequencies and proportions with 95% confidence intervals (CI). Associations between categorical variables were assessed using the chi-square test. Cramér's V was used to assess the strength of these associations. RESULTS Of 804 inpatients surveyed, 261 (32.5%) (95% CI 29.2-35.7) were prescribed 416 antibiotics, 137 were female (52.5%) and 198 adults (75.9%). One hundred and twenty-two (46.7%) patients received one antibiotic, 47.5% (124/261) received two, and 5.7% (15/261) received three or more antibiotics. The intensive care units had a higher ABU (68.6%, 35/51) compared to medical (31.3%, 120/384) and surgical (28.5%, 105/369) wards (p = 0.005, Cramér's V = 0.2). Lower respiratory tract infection (27.4%, 104/379), skin and soft tissue infections (SST) (23.5%, 89/379), and obstetrics and gynaecology prophylaxis (14.0%, 53/379) were the common diagnoses for antibiotic prescriptions. The three most prescribed antibiotic classes were imidazoles (21.9%, 91/416), third-generation cephalosporins (20.7%, 86/416) and combination penicillin (18.5%, 79/416). Access antibiotics accounted for 70.2% (292/416) of prescriptions and Watch antibiotics for 29.6% (123/416) (p = 0.110, Cramér's V = 0.1). Reasons for prescribing and treatment plans were documented in 64.9% (270/416) (95% CI 60.3-69.5) and 21.4% (89/416) (95% CI 17.3-25.3) of prescriptions, respectively. CONCLUSIONS The study serves as a baseline for ABU surveillance at the five regional hospitals in Limpopo Province. Lack of documentation indicates poor prescribing practices; ASP should address gaps by deploying evidence-based, multifaceted and stepwise interventions.

Systemic Corticosteroids for Treating Respiratory Diseases: Less Is Better, but… When and How Is It Possible in Real Life? Pulm Ther 2023; 9:329-344. [PMID: 37356085 PMCID: PMC10447722 DOI: 10.1007/s41030-023-00227-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 04/28/2023] [Indexed: 06/27/2023] Open
Abstract
Systemic corticosteroids (CSs), a keystone in pulmonology, are drugs with strong antiinflammatory activity. They are cheap, easily available, and accessible, but with common and serious side effects. Moreover, the use of exogenous CSs may suppress the hypothalamic-pituitary-adrenal (HPA) axis, predisposing to adrenal insufficiency. Safe CS treatment is a challenge of pharmacological research. This narrative review examined the indications of CSs in some respiratory diseases, analyzing what types, dosages, and length of treatment are required as the dosage and duration of CS treatments need to be minimized. Chronic maintenance treatments with CSs are associated with poor prognosis, but they are still prescribed in patients with severe asthma, Chronic obstructive pulmonary disease (COPD), and interstitial lung diseases. When CS discontinuation is not possible, all efforts should be made to achieve clinically meaningful reductions. Guidelines suggest the use of methylprednisolone at a dose of 20-40 mg/day or equivalent for up to 10 days in subjects with COVID-19 pneumonia (but not other respiratory viral diseases) and respiratory failure, exacerbations of asthma, and COPD. Some guidelines suggest that CS treatment shorter than 10-14 days can be abruptly stopped, strictly monitoring subjects with unexplained symptoms after CS withdrawal, who should promptly be tested for adrenal insufficiency (AI) and eventually treated. CSs are often used in severe community-acquired pneumonia associated with markedly increased serum inflammation markers, in acute respiratory distress syndrome (ARDS), in septic shock unresponsive to hydro-saline replenishment and vasopressors, and acute exacerbations of interstitial lung diseases. As these cases often require higher doses and longer duration of CS treatment, CS tapering should be gradual and, when useful, supported by an evaluation of HPA axis function.

Abstract
Background Bronchiectasis is a chronic lung disorder that affects the lives of many South Africans. Post-tuberculosis (TB) bronchiectasis is an important complication of previous pulmonary TB and a common cause of bronchiectasis in South Africa (SA). No previous statements on the management of bronchiectasis in SA have been published. Objectives To provide a position statement that will act as a template for the management of adult patients with bronchiectasis in SA. Methods The South African Thoracic Society appointed an editorial committee to compile a position statement on the management of adult non-cystic fibrosis (CF) bronchiectasis in SA. Results A position statement addressing the management of non-CF bronchiectasis in adults in SA was compiled. This position statement covers the epidemiology, aetiology, diagnosis, investigations and various aspects of management of adult patients with non-CF bronchiectasis in SA. Conclusion Bronchiectasis has largely been a neglected lung condition, but new research has improved the outlook for patients. Collaboration between interprofessional team members in patient management is important. In SA, more research into the epidemiology of bronchiectasis, especially post-TB bronchiectasis and HIV-associated bronchiectasis, is required. Abstract The South African Thoracic Society mandated a multidisciplinary team of healthcare providers to compile a position statement on the management of non-cystic fibrosis bronchiectasis in South Africa (SA). International guidelines on the management of bronchiectasis were reviewed and used as a basis from which the current position statement was compiled. This is the first position statement on the management of adult non-cystic fibrosis bronchiectasis in SA. A description of the epidemiology and aetiology of bronchiectasis is provided, as well as guidance on its diagnosis and management. The position statement provides guidance on the management of bronchiectasis to healthcare providers, policymakers and regulatory authorities.

Abstract
INTRODUCTION International guidelines provide heterogenous guidance on use of corticosteroids for community-acquired pneumonia (CAP). METHODS We performed a systematic review of randomized controlled trials examining corticosteroids in hospitalized adult patients with suspected or probable CAP. We performed a pairwise and dose-response meta-analysis using the restricted maximum likelihood (REML) heterogeneity estimator. We assessed the certainty of the evidence using GRADE methodology and the credibility of subgroups using the ICEMAN tool. RESULTS We identified 18 eligible studies that included 4661 patients. Corticosteroids probably reduce mortality in more severe CAP (RR 0.62 [95% CI 0.45 to 0.85]; moderate certainty) with possibly no effect in less severe CAP (RR 1.08 [95% CI 0.83 to 1.42]; low certainty). We found a non-linear dose-response relationship between corticosteroids and mortality, suggesting an optimal dose of approximately 6 mg of dexamethasone (or equivalent) for a duration of therapy of 7 days (RR 0.44 [95% 0.30 to 0.66]). Corticosteroids probably reduce the risk of requiring invasive mechanical ventilation (RR 0.56 [95% CI 0.42 to 74] and probably reduce intensive care unit (ICU) admission (RR 0.65 [95% CI 0.43 to 0.97]) (both moderate certainty). Corticosteroids may reduce the duration of hospitalization and ICU stay (both low certainty). Corticosteroids may increase the risk of hyperglycemia (RR 1.76 [95% CI 1.46 to 2.14]) (low certainty). CONCLUSION Moderate certainty evidence indicates that corticosteroids reduce mortality in patients with more severe CAP, the need for invasive mechanical ventilation, and ICU admission.

Fekadu G, Wang Y, You JHS. Standard diagnostics with and without urine-based lipoarabinomannan testing for tuberculosis disease in HIV-infected patients in a high-burden setting-A cost-effectiveness analysis. PLoS One 2023; 18:e0288605. [PMID: 37450476 PMCID: PMC10348570 DOI: 10.1371/journal.pone.0288605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Accepted: 07/02/2023] [Indexed: 07/18/2023] Open
Abstract
BACKGROUND Recent clinical findings reported the reduced mortality associated with treatment guided by sputum-based molecular test with urine-based lipoarabinomannan (LAM) assay for tuberculosis (TB) disease in HIV-infected individuals. We aimed to evaluate the cost-effectiveness of sputum-based Xpert tests with and without urine-based LAM assays among HIV-infected individuals with signs and symptoms of TB disease (TBD) from the perspective of South African healthcare providers. METHODS A one-year decision-analytic model was constructed to simulate TB-related outcomes of 7 strategies: Sputum smear microscope (SSM), Xpert, Xpert Ultra, Xpert with AlereLAM, Xpert Ultra with AlereLAM, Xpert with FujiLAM, and Xpert Ultra with FujiLAM, in a hypothetical cohort of adult HIV-infected individuals with signs and symptoms of TB. The model outcomes were TB-related direct medical cost, mortality, early treatment, disability-adjusted life-years (DALYs) and incremental cost per DALY averted (ICER). The model inputs were retrieved from literature and public data. Base-case analysis and sensitivity analysis were conducted. RESULTS In the base-case analysis, the Xpert Ultra with FujiLAM strategy showed the highest incidence of early treatment (267.7 per 1000 tested) and lowest mortality (29.0 per 1000 tested), with ICER = 676.9 USD/DALY averted. Probabilistic sensitivity analysis of 10,000 Monte Carlo simulations showed the cost-effective probability of Xpert Ultra with FujiLAM was the highest of all 7 strategies at the willingness-to-pay (WTP) threshold >202USD/DALY averted. CONCLUSION Standard sputum-based TB diagnostic Xpert Ultra with urine-based FujiLAM for TBD testing in HIV-infected individuals appears to be the preferred cost-effective strategy from the perspective of the health service provider of South Africa.

Efficacy and safety of adjunctive corticosteroids in the treatment of severe community-acquired pneumonia: a systematic review and meta-analysis of randomized controlled trials. Crit Care 2023; 27:274. [PMID: 37422686 PMCID: PMC10329791 DOI: 10.1186/s13054-023-04561-z] [Citation(s) in RCA: 22] [Impact Index Per Article: 22.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 07/04/2023] [Indexed: 07/10/2023] Open
Abstract
BACKGROUND This systematic review and meta-analysis aimed to investigate the clinical efficacy and safety of systemic corticosteroids in the treatment of patients with severe community-acquired pneumonia (sCAP). METHODS A comprehensive search was conducted using the Medline, Embase, ClinicalTrials.gov, and Scopus databases for articles published until April 24, 2023. Only randomized controlled trials (RCTs) that assessed the clinical efficacy and safety of adjunctive corticosteroids for treating sCAP were included. The primary outcome was the 30-day all-cause mortality. RESULTS A total of severe RCTs involving 1689 patients were included in this study. Overall, the study group had a lower mortality rate at day 30 than the control group (risk ratio [RR], 0.61; 95% CI 0.44 to 0.85; p < 0.01) with low heterogeneity (I2 = 0%, p = 0.42). Compared to the control group, the study group had a lower risk of the requirement of mechanical ventilation (RR 0.57; 95% CI 0.45 to 0.73; p < 0.001), shorter length of intensive care unit (MD - 0.8; 95% CI - 1.4 to - 0.1; p = 0.02), and hospital stay (MD - 1.1; 95% CI - 2.0 to - 0.1; p = 0.04). Finally, no significant difference was observed between the study and the control groups in terms of gastrointestinal tract bleeding (RR 1.03; 95% CI 0.49 to 2.18; p = 0.93), healthcare-associated infection (RR 0.89; 95% CI 0.60 to 1.32; p = 0.56), and acute kidney injury (RR 0.68; 95% CI 0.21 to 2.26; p = 0.53). CONCLUSIONS In patients with sCAP, adjunctive corticosteroids can provide survival benefits and improve clinical outcomes without increasing adverse events. However, because the pooled evidence remains inconclusive, further studies are required.

Effect of Corticosteroids on Mortality and Clinical Cure in Community-Acquired Pneumonia: A Systematic Review, Meta-analysis, and Meta-regression of Randomized Control Trials. Chest 2023; 163:484-497. [PMID: 36087797 PMCID: PMC10808071 DOI: 10.1016/j.chest.2022.08.2229] [Citation(s) in RCA: 34] [Impact Index Per Article: 34.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 07/07/2022] [Accepted: 08/27/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Community-acquired pneumonia (CAP) is a leading cause of morbidity and mortality. Corticosteroids may be a beneficial adjunct in the treatment of bacterial pneumonia. RESEARCH QUESTION Is there any benefit of corticosteroid therapy in the management of bacterial CAP among patients requiring hospitalization? STUDY DESIGN AND METHODS PubMed, Cochrane Library, and Embase were searched to identify randomized controlled trials assessing the use of systemic corticosteroids compared with standard care in the management of CAP. A systematic review, meta-analysis, and Trial Sequential Analysis (TSA) were performed. The primary outcome was all-cause mortality. Secondary outcomes included ICU admission, mechanical ventilation, treatment failure, readmission, and adverse events. Data are presented as risk ratio (RR) with 95% CI, P value, heterogeneity (I2), and TSA-adjusted CIs. RESULTS Sixteen trials met the eligibility criteria. All-cause mortality (16 studies [3,842 patients]; RR, 0.85 [95% CI, 0.67-1.07]; P = .17; I2 = 14%; TSA-adjusted CI, 0.61-1.09), ICU admission (six studies [2,619 patients]; RR, 0.66 [95% CI, 0.45-0.97]; P = .04; I2 = 0%; TSA-adjusted CI, 0.37-1.12), treatment failure (six studies [2,093 patients]; RR, 0.78 [95% CI, 0.37-1.67]; P = .52; I2 = 68%; TSA-adjusted CI, 0.02-25.5), and the incidence of adverse events (six studies [2,487 patients]; RR, 1.10 [95% CI, 0.97-1.25]; P = .14; I2 = 53%; TSA-adjusted CI, 0.82-2.41) were similar between patients receiving corticosteroids and patients assigned to the control group. The need for mechanical ventilation (eight studies [1,457 patients]; RR, 0.51 [95% CI, 0.33-0.77]; P = .001; I2 = 0%; TSA-adjusted CI, 0.20-0.85) was lower among patients receiving corticosteroids compared with those receiving standard care. However, corticosteroid use may be associated with higher rates of hospital readmission (five studies [2,853 patients]; RR, 1.20 [95% CI, 1.05-1.38]; P = .008; I2 = 0%; TSA-adjusted CI, 0.89-1.98). INTERPRETATION Corticosteroid therapy is associated with a lower incidence of progression to requiring mechanical ventilation among patients hospitalized with CAP. No association was found between corticosteroid therapy and mortality, treatment failure, or adverse events. TRIAL REGISTRY PROSPERO; No.: CRD42021279359; URL: https://www.crd.york.ac.uk/prospero/.

Abstract
Invasive pneumococcal disease (IPD) risk increases with age for older adults whereas the population size benefiting from pneumococcal vaccines and robustness of immunogenic response to vaccination decline. We estimate how demographics, vaccine efficacy/effectiveness (VE), and waning VE impact on optimal age for a single-dose pneumococcal vaccination. Age- and vaccine-serotype-specific IPD cases from routine surveillance of adults ≥ 55 years old (y), ≥ 4-years after infant-pneumococcal vaccine introduction and before 2020, and VE data from prior studies were used to estimate IPD incidence and waning VE which were then combined in a cohort model of vaccine impact. In Brazil, Malawi, South Africa and England 51, 51, 54 and 39% of adults older than 55 y were younger than 65 years old, with a smaller share of annual IPD cases reported among < 65 years old in England (4,657; 20%) than Brazil (186; 45%), Malawi (4; 63%), or South Africa (134, 48%). Vaccination at 55 years in Brazil, Malawi, and South Africa, and at 70 years in England had the greatest potential for IPD prevention. Here, we show that in low/middle-income countries, pneumococcal vaccines may prevent a substantial proportion of residual IPD burden if administered earlier in adulthood than is typical in high-income countries.

Sibanda M, Meyer JC, Godman B, Burnett RJ. Low influenza vaccine uptake by healthcare workers caring for the elderly in South African old age homes and primary healthcare facilities. BMC Public Health 2023; 23:91. [PMID: 36635715 PMCID: PMC9834679 DOI: 10.1186/s12889-022-14926-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Accepted: 12/21/2022] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND The elderly bear the highest burden of South Africa's estimated annual > 10 million influenza cases and > 11,000 influenza-related deaths. Unvaccinated healthcare workers (HCWs) are at high occupational risk of contracting influenza, and may transmit influenza to elderly patients in their care. Thus, the South African National Department of Health recommends that HCWs receive annual influenza vaccination. This study aimed to determine influenza vaccination coverage among HCWs; identify reasons for their vaccination status; and investigate if HCWs recommend vaccination to their elderly patients. METHODS A descriptive study was conducted in 18 community health centres and 44 private sector and non-governmental organisation managed old age homes across South Africa, using a self-administered structured questionnaire, which was distributed to 360 HCWs present on the day of data collection. Data were captured using Microsoft Excel® and imported to Epi Info™ 7 (Centers for Disease Control and Prevention, USA) for descriptive statistical analysis. Ethics approval (SMUREC/P/36/2018: PG) and permission to conduct the study at the facilities were obtained. All participants provided informed consent. RESULTS The response rate was 76.7% (276/360). Most participants were female (90.9% [251/276]), nursing professionals (81.2% [224/276]) with a mean age of 41.1 ± 11.7 years. Although 62.7% of participants indicated having ever received at least one dose of the influenza vaccine, influenza vaccine uptake for 2017 and 2018 was 24.36% (41/276) and 33.3% (92/276) respectively. The main reasons given for never being vaccinated against influenza were related to the unavailability of the vaccine (70.9%) and vaccine hesitancy (27.2%). Most participants (67.8% [187/276]) recommended vaccines to elderly patients in their care. CONCLUSION The main reasons behind low influenza vaccine uptake by HCWs in South Africa who care for the elderly were related to unavailability of the vaccine and vaccine hesitancy. Strategies to educate HCWs on the importance of influenza vaccination, while concurrently increasing sustained and easy access to the vaccine by HCWs are needed to preserve public health.

Utility of the BioFire ® FilmArray ® Pneumonia Panel plus assay for syndromic testing of lower respiratory tract infections in a low/middle-income setting. JAC Antimicrob Resist 2023; 5:dlac139. [PMID: 36628341 PMCID: PMC9825243 DOI: 10.1093/jacamr/dlac139] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Accepted: 12/15/2022] [Indexed: 01/09/2023] Open
Abstract
Background Determining lower respiratory tract infection (LRTI) aetiology is complex. Culture-based methods are laborious with poor sensitivity. Molecular assays improve detection of potential pathogens, but incorrect interpretation of results may lead to inappropriate antimicrobial therapy. Methods The utility of the BioFire® FilmArray® Pneumonia Panel plus (FA-PP) to detect LRTI pathogens, and the potential impact on antimicrobial stewardship in a low-resource setting, were assessed. Routine LRT samples were included from adult patients with clinically suspected LRTI or with a concomitant blood culture at Groote Schuur Hospital and referring facilities. Culture and FA-PP results were compared, and pharmacy data analysed to determine appropriateness of antibiotic therapy. Results There was an 80% correlation between cultured LRTI pathogens and the FA-PP bin ≥107 results. Compared with culture, the FA-PP detected substantially more pathogens (86.6% versus 17.9%) and produced a combined 100% positive percent agreement, and 88% negative percent agreement. The FA-PP detected bacterial/viral coinfections in 27% of samples. Correlation of FA-PP results with pharmacy data (n = 69) indicated a potential antibiotic change in 75% of cases, but this is difficult to accurately characterize without a 'gold standard' for treatment or complete clinical data. Conclusions The FA-PP increased the number of positive samples with typical bacteria, but the semi-quantitative reporting algorithm does not describe the correlation between the different bin values and colonization versus infection. This complicates result interpretation and may lead to inappropriate antimicrobial treatment. This study highlights the potential positive impact of rapid molecular assays for routine care in lower-income settings, but also underscores the interpretive challenges associated with these tests.

Abstract
Pneumococcal infections remain a common global cause of significant morbidity and mortality. The first recommendations for adult pneumococcal vaccination, published in South Africa in 1999, contained information only on the 23-valent polysaccharide vaccine (PPV23). With the introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) for use in adults and the perceived uncertainty that most clinicians had regarding use of these vaccines in adults, these vaccine recommendations were updated in 2022. A Working Group, which consisted of individuals in various fields of medical practice in South Africa, who were from different areas of the country, and included clinicians from both the public and private sectors, was assembled to revise the recommendations. The expertise of the participants varied widely, dependent on their training and specialty, and encompassed different organ systems, disease conditions, and/or practice types. Each participant was allocated a different section, based on their expertise, for which they were required to do an extensive review of the current literature and write their section. The entire working group then reviewed the complete document several times, following additional comments and recommendations. This update contains recommendations for the use of both PPV23 and PCV13, either alone, or in sequence, both in vaccine naïve and in previously vaccinated individuals. It includes both age and risk categories, and encompasses the elderly (≥65 years), as well as younger adults (<65 years) with comorbid conditions or with high-risk conditions and/or immunocompromise. It is hoped that this review and its associated vaccine recommendations will clarify for clinicians, from all spheres of practice in South Africa, how, where, and when pneumococcal vaccines should be used in adults, with the ultimate goal of significantly increasing the appropriate use of these vaccines, in order to decrease the substantial morbidity and mortality associated with pneumococcal infections in adults in South Africa. Furthermore, it is hoped that this review of local epidemiological data and the manner in which this information was interpreted in the development of these local vaccine recommendations, could be used as an example for other regions of the world, to tailor their recommendations to locally available epidemiological data.

OBJECTIVES We describe the use of a multi-pathogen platform, TaqMan array card (TAC) real-time PCR, for the detection of pathogens in patients hospitalized with severe respiratory illness (SRI). METHODS Prospective hospital-based syndromic surveillance for acute and chronic SRI was carried out at two sentinel sites in South Africa between January and December 2017. We tested respiratory specimens for 21 respiratory pathogens and blood samples for nine bacteria using TAC. Pathogen detection was compared by age group and HIV status using the chi-squared test. RESULTS During 2017, 956 patients of all ages were enrolled in the SRI surveillance, and of these, 637 (67%) patients were included in this study (637 blood, 487 naso- and oro-pharyngeal swabs and 411 sputum specimens tested). At least one pathogen was detected in 83% (527/637) of patients. Common pathogens detected included H. influenzae (225/637; 35%), S. pneumoniae (224/637; 35%), rhinovirus (144/637; 23%), S. aureus (129/637; 20%), K. pneumoniae (85/637; 13%), M. tuberculosis (75/637; 12%), and respiratory syncytial virus (57/637; 9%). Multiple pathogens (≥2) were co-detected in 57% (364/637) of patients. CONCLUSION While use of a multi-pathogen platform improved pathogen yield, pathogen co-detections were common and would need clinical assessment for usefulness in individual-level treatment and management decisions.

Antimicrobial Dispensing Practice in Community Pharmacies in Russia during the COVID-19 Pandemic. Antibiotics (Basel) 2022; 11:antibiotics11050586. [PMID: 35625230 PMCID: PMC9137661 DOI: 10.3390/antibiotics11050586] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 04/25/2022] [Accepted: 04/26/2022] [Indexed: 12/27/2022] Open
Abstract
COVID-19 has had a significant impact on health care systems, including drug use. The present study aimed to evaluate the patterns of community supply of antimicrobials from community pharmacies during the COVID-19 pandemic in five cities of Russia. In a cross-sectional study, a random sample of pharmacies reported all episodes of antimicrobials supply during a one-week period. Patterns of supply (age and gender of customer, drug name and formulation, prescription availability, indication, etc.) were analyzed. Altogether, 71 pharmacies took part in the study and 5270 encounters were recorded. In total, 4.2% of visits resulted in supply of more than one antimicrobial agent and 5.2% were for parenteral formulations. The rate of prescription-based purchase in participated cities varied from 40.5 to 99.1%. Systemic antibiotics and antivirals accounted for the majority of supplies (60.5 and 26.3%, respectively). Upper respiratory tract infections were reported as the indication for antimicrobials usage in 36.9% of cases, followed by skin and soft tissue infections (12.1%) and urinary tract infections (8.7%); COVID-19 accounted for 8.4% of all supplies. Amoxicillin with clavulanic acid, azithromycin and amoxicillin were indicated as the top three antimicrobials purchased for upper respiratory tract infections, and azithromycin, umifenovir and levofloxacin were the top three for COVID-19. In general, a high rate of drugs dispensing without prescription was revealed. Antibiotics for systemic use remained the most common antimicrobials, whereas presumably viral upper respiratory tract infections were the main reason for their purchase. COVID-19 infection itself was responsible for a small proportion of the supply of antimicrobial agents, but systemic antibiotics accounted for more than a half of supplies.

Effects of additive corticosteroid therapy on 90-day survival in patients with community-onset pneumonia. J Infect Chemother 2021; 28:496-503. [PMID: 34955409 DOI: 10.1016/j.jiac.2021.12.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Revised: 12/01/2021] [Accepted: 12/13/2021] [Indexed: 11/17/2022]
Abstract
INTRODUCTION Systemic corticosteroid therapy is occasionally used as an additive therapy, especially for patients with severe pneumonia. However, its recommendation for use in patients with pneumonia varies worldwide, and its efficacy is unclear. METHODS Adult Japanese patients hospitalized with community-onset pneumonia between January and December 2012 were analyzed using the Diagnostic Procedure Combination database. The patients were classified into mild-to-moderate and severe groups using the A-DROP (age, dehydration, respiration, orientation, and blood pressure) system. The 90-day survival rate was evaluated between the presence or absence of corticosteroid treatment using the Kaplan-Meier method in the overall, mild-to-moderate and severe groups, respectively. The patients' clinical characteristics were adjusted between the two groups using the inverse probability of treatment weighting method. RESULTS Among 123,811, 110,534 patients were classified as mild-to-moderate grade (corticosteroid group: 8,465, non-corticosteroid group: 102,069) and 13,277 patients were classified as severe grade (corticosteroid group: 1,338, non-corticosteroid group: 11,939). The 90-day survival rate was higher in the non-corticosteroid group than in the corticosteroid group in patients with pneumonia of overall grade (weighted hazard ratio [HR]: 1.36; P < 0.001) and those with mild-to-moderate grade (weighted HR: 1.46; P < 0.001). However, there were no significant differences in the outcomes between the two groups in those with severe grade (weighted HR: 1.08; P = 0.38). CONCLUSIONS Additive systemic corticosteroid therapy may be related to poor 90-day prognosis in patients with mild-to-moderate grade community-onset pneumonia, although it may not be positively associated with its prognosis in those with severe grade.

Abstract
Treponema pallidum macrolide resistance and clinical treatment failure have emerged rapidly within communities where macrolides have been used as convenient, oral therapeutic alternatives to benzathine penicillin G for syphilis or for other clinical indications. Macrolides are not included in the South African syndromic management guidelines for genital ulcer disease; however, in 2015, a 1-g dose of azithromycin was incorporated into treatment algorithms for genital discharge. We determined the prevalence of 23S rRNA macrolide resistance-associated point mutations in 135 T. pallidum-positive surveillance specimens from Botswana, Zimbabwe, and South Africa between 2008 and 2018. Additionally, we investigated the association between macrolide resistance, T. pallidum strain type, and HIV coinfection. A significant increase in the prevalence of the A2058G macrolide resistance-associated point mutation was observed in specimens collected after 2015. There was a high level of molecular heterogeneity among T. pallidum strains circulating in the study communities, with strain type 14d/f being the most predominant in South Africa. Fourteen novel strain types, derived from three new tpr gene restriction fragment length polymorphism patterns and seven new tp0548 gene sequence types, were identified. There was an association between A2058G-associated macrolide resistance and T. pallidum strain types 14d/f and 14d/g but no association between T. pallidum macrolide resistance and HIV coinfection. The majority of T. pallidum strains, as well as strains containing the A2058G mutation, belonged to the SS14-like clade. This is the first study to extensively detail the molecular epidemiology and emergence of macrolide resistance in T. pallidum in southern Africa.

Abstract
Community-acquired pneumonia (CAP) refers to infectious inflammation of the lung parenchyma developing outside of a hospital. CAP has quite a high mortality and morbidity rate worldwide, and especially among elderly patients. The increasing burden of CAP is due to antibiotic resistance, the growth of the elderly population, and underlying comorbidities. Streptococcus pneumoniae remains the most common bacterial pathogen causing CAP, but multi-drug resistance bacteria and potential pathogens have increased the difficulty and challenges of managing CAP. Although preventive measures, diagnostic techniques, and treatment strategies are constantly advancing and improving, the susceptibility of multi-drug resistant pathogens, such as including Methicillin-Resistant Staphylococcus aureus (MRSA), Klebsiella pneumoniae, and Pseudomonas aeruginosa, has not improved significantly in recent decades, thus highlighting the importance and necessity of developing new antibiotics for the treatment of CAP. New antimicrobials have been approved over the past few years that will expand treatment options for CAP, and especially for patients with potential comorbidities. This situation also offers the chance to reduce the abuse of antibiotics, their toxicities, and their adverse reactions and to provide effective personalized antibiotic treatment.

Abstract
BACKGROUND South Africa has the highest prevalence of HIV in the world and to date has recorded the highest number of cases of COVID-19 in Africa. There is uncertainty as to what the significance of this dual infection is, and whether people living with HIV (PLWH) have worse outcomes compared to HIV-negative patients with COVID-19. This study compared the outcomes of COVID-19 in a group of HIV-positive and HIV-negative patients admitted to a tertiary referral centre in Johannesburg, South Africa. METHODS Data was collected on all adult patients with known HIV status and COVID-19, confirmed by reverse-transcriptase polymerase chain reaction (RT-PCR), admitted to the medical wards and intensive care unit (ICU) between 6 March and 11 September 2020. The data included demographics, co-morbidities, laboratory results, severity of illness scores, complications and mortality, and comparisons were made between the HIV-positive and HIV negative groups. RESULTS Three-hundred and eighty-four patients, 108 HIV-positive and 276 HIV-negative, were included in the study. Median 4C score was significantly higher in the HIV-positive patients compared to the HIV-negative patients, but there was no significant difference in mortality between the HIV-positive and HIV-negative groups (15% vs 20%, p = 0.31). In addition, HIV-positive patients who died were younger than their HIV-negative counterparts, but this was not statistically significant (47.5 vs 57 years, p = 0.06). CONCLUSION Our findings suggest that HIV is not a risk factor for moderate or severe COVID-19 disease neither is it a risk factor for mortality. However, HIV-positive patients with COVID-19 requiring admission to hospital are more likely to be younger than their HIV-negative counterparts. These findings need to be confirmed in future, prospective, studies.

Abstract
OBJECTIVES Guidelines that include antimicrobial recommendations should explicitly consider contextual factors that influence antimicrobial resistance and their downstream effects on resistance selection. The objectives were to analyse (1) how, and to what extent, tuberculosis, gonorrhoea and respiratory tract infection guidelines are considering antimicrobial resistance; (2) are of acceptable quality and (3) if they can be easily contextualised to fit the needs of specific populations and health systems. METHODS We conducted a systematic review and searched Ovid MEDLINE and Embase from 1 January 2007 to 7 June 2019 for tuberculosis, gonorrhoea and respiratory tract infection guidelines published in English. We also searched guideline databases, key websites and reference lists. We identified guidelines and recommendations that considered contextual factors including antimicrobial resistance, values, resource use, equity, acceptability and feasibility. We assessed quality of the guidelines using the Appraisal of Guidelines for Research and Evaluation II tool focusing on the domains scope and purpose, rigour of development, and editorial independence. RESULTS We screened 10 365 records, of which 74 guidelines met inclusion criteria. Of these guidelines, 39% (n=29/74) met acceptable quality scores. Approximately two-thirds of recommendations considered antimicrobial resistance at the population and/or outcome level. Five of the 29 guidelines reported all factors required for recommendation contextualisation. Equity was the least considered across guidelines. DISCUSSION Relatively few guidelines for highly prevalent infectious diseases are considering resistance at a local level, and many do not consider contextual factors necessary for appropriate antimicrobial use. Improving the quality of guidelines targeting specific regional areas is required. PROSPERO REGISTRATION NUMBER CRD42020145235.

Abstract
BACKGROUND Lower respiratory tract infections continue to contribute significantly to morbidity and mortality across all age groups globally. In sub-Saharan Africa, many studies of community acquired pneumonia in adults have focused on HIV-infected patients and little attention has been given to risk factors and etiologic agents in an urban area with a more moderate HIV prevalence. METHODS We prospectively enrolled 77 patients admitted to a 280 bed teaching hospital in Kenya with radiographically confirmed community acquired pneumonia from May 2019 to March 2020. The patients were followed for etiology and clinical outcomes. Viral PCR testing was performed using the FTD respiratory pathogen-21 multiplex kit on nasopharyngeal or lower respiratory samples. Additional microbiologic workup was performed as determined by the treating physicians. RESULTS A potential etiologic agent(s) was identified in 57% including 43% viral, 5% combined viral and bacterial, 5% bacterial and 4% Pneumocystis. The most common etiologic agent was Influenza A which was associated with severe clinical disease. The most common underlying conditions were cardiovascular disease, diabetes and lung disease, while HIV infection was identified in only 13% of patients. Critical care admission was required for 24, and 31% had acute kidney injury, sometimes in combination with acute respiratory distress or sepsis. CONCLUSION Viruses, especially influenza, were commonly found in patients with CAP. In contrast to other studies from sub-Saharan Africa, the underlying conditions were similar to those reported in high resource areas and point to the growing concern of the double burden of infectious and noncommunicable diseases.

Abstract
The World Health Organization estimates that globally, the proportion of people aged ≥60 years will more than double by the year 2050, with the majority of elderly people living in low- and middle-income countries such as South Africa. Population ageing is an impending public health concern, potentially negatively impacting on South Africa's economy and health system if the government does not adequately prepare for this change. Globally, many potential solutions to ensure healthy ageing are being discussed and implemented, including adopting a “life-course” approach to vaccination which includes vaccination of the elderly, since they are at considerable risk of severe morbidity and mortality from vaccine-preventable diseases. While vaccines are considered as one of the greatest tools for preventing childhood infectious disease morbidity and mortality, they are under-utilised in strategies for promoting healthy ageing in South Africa, where only influenza vaccination is available free of charge to the elderly accessing public sector healthcare. Population ageing coupled with the high incidence of vaccine-preventable diseases amongst elderly South Africans, necessitates establishing a comprehensive national policy and guidelines for vaccination of the elderly.

Abstract
Community-acquired pneumonia (CAP) is severe disease. Early prescription of an adequate treatment has a positive impact in the CAP outcome. Despite the evidence of existing relevant differences between CAP across geographical areas, general guidelines can be designed to be applied everywhere. Eight years have passed between the publication of the European (EG) and American (AG) CAP guidelines, thus the aim of this narrative review is to compare both guidelines and summarize their recommendations. The main similarity between both guidelines is the antibiotics recommendation with the exception that AG mention new antimicrobials that were not available at the time of EG publication. Both guidelines recommend against routinely adding steroids as an adjuvant treatment. Finally, both guidelines acknowledge that the decision to hospitalize a patient is clinical and should be complemented with an objective tool for risk assessment. EG recommend the CRB-65 while AG recommend the Pneumonia Severity Index (PSI). EG and AG share a similar core of recommendations and only differ in minor issues such as new antibiotics. Likewise, both guidelines recommend against the routine prescription of steroids as an adjuvant therapy.

Med Mycol 2021; 59:802-812. [PMID: 33578417 DOI: 10.1093/mmy/myab002] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 11/30/2020] [Accepted: 01/08/2021] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND The epidemiology of Pneumocystis jirovecii, known to colonize the respiratory tract and cause a life-threatening HIV-associated pneumonia (PCP), is poorly described in Africa. We conducted a systematic review to evaluate P. jirovecii prevalence in African HIV-positive adults with or without respiratory symptoms. METHODS We searched Medline, Embase, Cochrane library, Africa-Wide, and Web of Science for studies employing PCR and/or microscopy for P. jirovecii detection in respiratory samples from HIV-positive adults in Africa between 1995 and 2020. Prevalence with respiratory symptoms was pooled using random-effect meta-analysis, and stratified by laboratory method, sample tested, study setting, CD4 count, and trimethoprim/sulfamethoxazole prophylaxis. Colonization prevalence in asymptomatic adults and in adults with non-PCP respiratory disease was described, and quantitative PCR (qPCR) thresholds to distinguish colonization from microscopy-confirmed PCP reviewed. RESULTS Thirty-two studies were included, with 27 studies (87%) at high risk of selection bias. P. jirovecii was detected in 19% [95% confidence interval (CI): 12-27%] of 3583 symptomatic and in 9% [95% CI: 0-45%] of 140 asymptomatic adults. Among symptomatic adults, prevalence was 22% [95% CI: 12-35%] by PCR and 15% [95% CI: 9-23%] by microscopy. Seven percent of 435 symptomatic adults had PCR-detected Pneumocystis colonization without evidence of PCP [95% CI: 5-10%, four studies]. One study established a qPCR cutoff of 78 copies/5μl of DNA in 305 induced sputum samples to distinguish Pneumocystis colonization from microscopy-confirmed PCP. CONCLUSION Despite widened access to HIV services, P. jirovecii remains common in Africa. Prevalence estimates and qPCR-based definitions of colonization are limited, and overall quality of studies is low.

Abstract
PURPOSE OF REVIEW We highlight the recent advances in the guidelines for treating patients with severe community-acquired pneumonia (sCAP). RECENT FINDINGS sCAP is a significant cause of hospital admissions. We performed an extensive review of the literature, covering studies from the last several years, to summarise the most important points in the diagnosis and treatment of patients hospitalised with sCAP. SUMMARY sCAP is associated with a high clinical burden. Therefore, deep knowledge is necessary for its management. In general, diagnosis, treatment and management are based on many published guidelines. However, the mortality rate is still unacceptably high, indicating the need for clear recommendations in the management of patients with sCAP. The choice of empirical antibiotic therapy for sCAP depends on multiple factors, such as national and local antimicrobial susceptibility data and the characteristics of the patients, including their risk factors for acquiring infections caused by multidrug-resistant pathogens. Currently, there are several published international guidelines. The aim of this review is to explore the areas that require further knowledge and new recommendations for current clinical practice.

The Performance of CURB-65 and PSI for Predicting In-Hospital Mortality of Community-Acquired Pneumonia in Patients with Type 2 Diabetes Compared with the Non-Diabetic Population. Diabetes Metab Syndr Obes 2021; 14:1359-1366. [PMID: 33790603 PMCID: PMC8001112 DOI: 10.2147/dmso.s303124] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Accepted: 03/08/2021] [Indexed: 01/29/2023] Open
Abstract
OBJECTIVE To compare the performance of CURB-65 and Pneumonia Severity Index (PSI) for predicting in-hospital mortality of community-acquired pneumonia (CAP) between patients with and without type 2 diabetes (T2DM). METHODS A retrospective study was conducted on 2365 CAP patients in The First Hospital of Qinhuangdao, China. The primary outcome was in-hospital mortality. The area under curves (AUCs) was used to evaluate the abilities of CRB-65, CURB-65, and PSI class for predicting in-hospital mortality in patients with CAP. RESULTS Among CAP patients, 127 patients (5.4%) died, 80 patients were without diabetes, and 47 patients had T2DM. In-hospital mortality increased with the risk stratification defined as CURB-65 and PSI class in both non-diabetes and T2DM patients (P<0.05). The AUCs for predicting in-hospital mortality were 0.728~0.798 in patients without T2DM (CRB-65: 0.728, CURB-65: 0.757 and PSI class: 0.798) and 0.641~0.716 in patients with T2DM (CRB-65: 0.641, CURB-65: 0.677 and PSI class: 0.716)(P<0.001). The AUC of the PSI class was lower in patients with T2DM than in patients without T2DM (P<0.05). CONCLUSION CURB-65 and PSI class are correlated with in-hospital mortality of CAP in patients with and without T2DM. Compared with non-diabetes patients, the predictive performance of CURB-65 and PSI class decreased in patients with T2DM. A prediction model for evaluating the CAP severity in the T2DM population should be developed by future studies.

Abstract
Background: We evaluated bacterial nasopharyngeal carriage (NPC) prevalence and cumulative acquisition following 7-valent pneumococcal conjugate vaccine (PCV7) or pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) administration. Methods: Participants were children from two clinical trials in a South African center who received PCV7 (n = 250) or PHiD-CV (n = 100) at ~6 weeks, ~14 weeks, and ~9-10 months of age, and were enrolled between Dec2009-Apr2010 and Mar2009-May2010 in the PCV7 and PHiD-CV studies, respectively. Sample collection, most microbiological assessments, and data re-analysis methods were identical. Results: NPC prevalence of any pneumococcal serotype was 18.5% and 17.0% at pre-vaccination, and 63.1% and 67.3% in 24-27 month-old children among PCV7 and PHiD-CV recipients, respectively. In 24-27 month-old children, 96.1% and 99.0% of PCV7 and PHiD-CV recipients had acquired ≥1 pneumococcal serotype, 53.7% and 62.9% ≥1 PCV7 serotype, 1.5%, and 3.1% ≥1 of serotypes 1, 5 or 7F, 23.2% and 19.6% serotype 6A, 23.2% and 21.7% serotype 19A, 88.7%, and 91.0% H. influenzae, and 50.3% and 62.9% Staphylococcus aureus, respectively. Conclusions: This analysis of two concurrent clinical trials did not reveal differences in bacterial NPC prevalence or acquisition in PCV7- and PHiD-CV-vaccinated children. Trial registration: South African National Clinical Trial Register (NHREC DOH-27-0511-299); ClinicalTrials.gov (NCT00829010).

Abstract
INTRODUCTION Pharmacists in low-middle-income countries (LMIC) are few and lack antibiotic stewardship (AS) training. The ability was assessed of non-specialised pharmacists to implement stewardship interventions and improve adherence to the South African community-acquired pneumonia (CAP) guideline in public and private hospitals. METHODS This was a multicentre, prospective cohort study of adult CAP patients hospitalised between July 2017 and July 2018. A CAP bundle was developed of seven process measures (diagnostic and AS) that pharmacists used to audit compliance and provide feedback. CAP bundle compliance rates and change in outcome measures [mortality, length of stay (LOS) and infection-related (IR)-LOS] during pre- and post-implementation periods were compared. RESULTS In total, 2464 patients in 39 hospitals were included in the final analysis. Post-implementation, overall CAP bundle compliance improved from 47·8% to 53·6% (confidence interval [CI] 4·1-7·5, p<0·0001), diagnostic stewardship compliance improved from 49·1% to 54·6% (CI 3·3-7·7, p<0·0001) and compliance with AS process measures from 45·3% to 51·6% (CI 4·0-8·6, p<0·0001). Improved compliance with process measures was significant for five (2 diagnostic, 3 AS) of seven components: radiology, laboratory, antibiotic choice, duration and intravenous to oral switch. There was no difference in mortality between the two phases, [4·4%(55/1247) vs. 3·9%(47/1217); p=0·54], median LOS or IR LOS 6·0 vs. 6·0 days (p=0·20) and 5·0 vs. 5·0 days (p=0·40). CONCLUSION Non-specialised pharmacists in public and private hospitals implemented stewardship interventions and improved compliance to SA CAP guidelines. The methodology of upskilling and a shared learning stewardship model may benefit LMIC countries.

Abstract
Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality both in the USA and globally. As the burden of CAP continues to increase due to several factors, the advances in its diagnosis, prevention, and treatment have taken on even greater interest and importance. The majority of CAP patients are treated empirically, and selection of appropriate antibiotic treatment is increasingly difficult because the epidemiology of CAP is changing, in part due to antimicrobial resistance, and the causative CAP pathogens differ between countries and regions. There is also an increasing prevalence of chronic co-morbid diseases among CAP patients. Treatment of CAP has become challenging because of these factors along with the varying safety profiles and efficacy of well-established antibiotics, as well as limited new therapeutic options. Recently, however, new antibiotics have been approved, which will expand the treatment options for CAP, particularly in those patients with underlying complications. Recently approved delafloxacin, an anionic fluoroquinolone, has a unique structure and distinct chemical characteristics; it demonstrated non-inferiority to moxifloxacin in a phase III clinical trial, but was shown to be superior to moxifloxacin at early clinical response in CAP patients who also have chronic obstructive pulmonary disease (COPD) or asthma as a co-morbidity, and in CAP patients who may have severe illness. Delafloxacin could offer an additional therapy against resistant isolates and among these difficult-to-treat patients. This review summarizes the development, latest research, and safety profile of the new antibiotic delafloxacin, and its potential future role in the treatment of CAP.

Abstract
Background
Community-acquired pneumonia (CAP) is a common condition, with mortality increasing in patients who require intensive
care unit (ICU) admission. A better understanding of the current aetiology of severe CAP will aid clinicians in requesting appropriate
diagnostic tests and initiating appropriate empiric antimicrobials.
Objectives
To assess the comorbidities, aetiology and mortality associated with severe CAP in a tertiary ICU in Cape Town, South Africa.
Methods
We retrospectively analysed a prospective registry of all adults admitted to the medical intensive care unit at Tygerberg Hospital
with severe CAP over a 1-year period.
Results
We identified 74 patients (mean (SD) age 40.0 (15.5) years; 44 females). The patients had a mean (SD) APACHE II score of
21.4 (7.9), and the mean ICU stay was 6.6 days. Of the 74 patients, 16 (21.6%) died in ICU. Non-survivors had a higher mean (SD) APACHE
II score than survivors (28.3 (6.8) v. 19.4 (7.1); p<0.001). Mycobacterium tuberculosis (n=16; 21.6%) was the single most common agent
identified, followed by Pseudomonas aeruginosa (n=9; 12.2%). All P. aeruginosa isolates were sensitive to first-line treatment. No organism
was identified in 32 patients (43.2%).
Conclusion M. tuberculosis was the single most common agent identified in patients presenting with CAP. The mortality of CAP requiring
invasive ventilation was relatively low, with a strong association between mortality and a higher APACHE II score.

Abstract
Streptococcus pneumoniae (pneumococcus) remains an important cause of morbidity and mortality. Pneumococcal vaccination is part of the South African pediatric public immunization program but the potential cost-effectiveness of such an intervention for adults is unknown. This study aimed to compare the cost-effectiveness of two widely used pneumococcal vaccines: pneumococcal conjugate vaccine (PCV13) and pneumococcal polysaccharide vaccine (PPSV23) in South African adults, 18 years and older. Four analyses were carried out in a) both the private and public health care sectors; and b) for the HIV-infected population alone and for the total mixed population (all HIV-infected and -uninfected people). A previously published global pharmacoeconomic model was adapted and populated to represent the South African adult population. The model utilized a Markov-type process to depict the lifetime clinical and economic outcomes of patients who acquire pneumococcal disease in 2015, from a societal perspective. Costs were sourced in South African rand and converted to US dollar (USD). The incremental cost divided by the incremental effectiveness (expressed as quality-adjusted life years gained) represented the incremental cost-effectiveness ratio for PCV13 compared to PPSV23. Results indicated that the use of PCV13 compared to PPSV23 is highly cost-effective in the public sector cohorts with incremental cost-effectiveness ratios of $771 (R11,106)/quality-adjusted life year and $956 (R13,773)/quality-adjusted life year for the HIV-infected and mixed populations, respectively. The private sector cohort showed similar highly cost-effective results for the mixed population (incremental cost-effectiveness ratio $626 (R9,013)/quality-adjusted life year) and the HIV-infected cohort (dominant). In sensitivity analysis, the model was sensitive to vaccine price and effectiveness. Probabilistic sensitivity analyses found predominantly cost-effective ICERs. From a societal perspective, these findings provide some guidance to policy makers for consideration and implementation of an immunization strategy for both the public and private sector and amongst different adult patient pools in South Africa.

Diabetes Metab Syndr Obes 2020; 13:3617-3626. [PMID: 33116713 PMCID: PMC7553637 DOI: 10.2147/dmso.s268679] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Accepted: 09/02/2020] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE The aim of this study was to develop a tool for predicting in-hospital mortality of community-acquired pneumonia (CAP) in patients with type 2 diabetes (T2DM). METHODS A retrospective study was conducted on 531 CAP patients with T2DM at The First Hospital of Qinhuangdao. The primary outcome was in-hospital mortality. Variables to develop the nomogram were selected using multiple logistic regression analysis. Discrimination was evaluated using receiver operating characteristic (ROC) curve. Calibration was evaluated using the Hosmer-Lemeshow test and calibration plot. RESULTS Multiple logistic regression analysis showed that age, pulse, urea and albumin (APUA) were independent risk predictors. Based on these results, we developed a nomogram (APUA model) for predicting in-hospital mortality of CAP in T2DM patients. In the training set, the area under the curve (AUC) of the APUA model was 0.814 (95% CI: 0.770-0.853), which was higher than the AUCs of albumin alone, CURB-65 and Pneumonia Severity Index (PSI) class (p<0.05). The Hosmer-Lemeshow test (χ 2=5.298, p=0.808) and calibration plot (p=0.802) showed excellent agreement between the predicted possibility and the actual observation in the APUA model. The results of the validation set were similar to those of the training set. CONCLUSION The APUA model is a simple and accurate tool for predicting in-hospital mortality of CAP, adapted for patients with T2DM. The predictive performance of the APUA model was better than CURB-65 and PSI class.

Etiology and Risk Factors for Mortality in an Adult Community-acquired Pneumonia Cohort in Malawi. Am J Respir Crit Care Med 2019; 200:359-369. [PMID: 30625278 PMCID: PMC6680311 DOI: 10.1164/rccm.201807-1333oc] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Accepted: 01/09/2019] [Indexed: 01/12/2023] Open
Abstract
Rationale: In the context of rapid antiretroviral therapy rollout and an increasing burden of noncommunicable diseases, there are few contemporary data describing the etiology and outcome of community-acquired pneumonia (CAP) in sub-Saharan Africa.Objectives: To describe the current etiology of CAP in Malawi and identify risk factors for mortality.Methods: We conducted a prospective observational study of adults hospitalized with CAP to a teaching hospital in Blantyre, Malawi. Etiology was defined by blood culture, Streptococcus pneumoniae urinary antigen detection, sputum mycobacterial culture and Xpert MTB/RIF, and nasopharyngeal aspirate multiplex PCR.Measurements and Main Results: In 459 patients (285 [62.1%] males; median age, 34.7 [interquartile range, 29.4-41.9] yr), 30-day mortality was 14.6% (64/439) and associated with male sex (adjusted odds ratio, 2.60 [95% confidence interval, 1.17-5.78]), symptom duration greater than 7 days (2.78 [1.40-5.54]), tachycardia (2.99 [1.48-6.06]), hypoxemia (4.40 [2.03-9.51]), and inability to stand (3.59 [1.72-7.50]). HIV was common (355/453; 78.4%), frequently newly diagnosed (124/355; 34.9%), but not associated with mortality. S. pneumoniae (98/458; 21.4%) and Mycobacterium tuberculosis (75/326; 23.0%) were the most frequently identified pathogens. Viral infection occurred in 32.6% (148/454) with influenza (40/454; 8.8%) most common. Bacterial-viral coinfection occurred in 9.1% (28/307). Detection of M. tuberculosis was associated with mortality (adjusted odds ratio, 2.44 [1.19-5.01]).Conclusions: In the antiretroviral therapy era, CAP in Malawi remains predominantly HIV associated, with a large proportion attributable to potentially vaccine-preventable pathogens. Strategies to increase early detection and treatment of tuberculosis and improve supportive care, in particular the correction of hypoxemia, should be evaluated in clinical trials to address CAP-associated mortality.

Abstract
PURPOSE OF REVIEW The first guidelines on community-acquired pneumonia (CAP) were published in 1993, but since then many of the challenges regarding the outpatient management of CAP persist. These include the difficulty in establishing the initial clinical diagnosis, its risk stratification, which will dictate the place of treatment, the empirical choice of antibiotics, the relative scarcity of novel antibiotics and the importance of knowing local microbiological susceptibility patterns. RECENT FINDINGS New molecular biology methods have changed the etiologic perspective of CAP, especially the contribution of virus. Lung ultrasound and biomarkers might aid diagnosis and severity stratification in the outpatient setting. Antibiotic resistance is a growing problem that reinforces the importance of novel antibiotics. And finally, prevention and the use of anti-pneumococcal vaccine are instrumental in reducing the burden of disease. SUMMARY Most of CAP cases are managed in the community; however, most research comes from hospitalized severe patients. New and awaited advances might contribute to aid diagnosis, cause and assessment of patients with CAP in the community. This knowledge might prove decisive in the execution of stewardship programmes that maintain current antibiotics, safeguard future ones and reinforce prevention.

Medicine (Baltimore) 2019; 98:e14636. [PMID: 30921179 PMCID: PMC6456091 DOI: 10.1097/md.0000000000014636] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2018] [Revised: 12/13/2018] [Accepted: 01/22/2019] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND The systemic use of corticosteroids for patients in severe community-acquired pneumonia (CAP) remains disputed in clinical practice. We undertook a systematic review and meta-analysis to assess the efficacy and safety of corticosteroids in patients with severe CAP. METHODS We searched MEDLINE (1946 to June 2018), EMBASE (1966 to June 2018), and the Cochrane Library database for randomized controlled trials (RCTs) conducted for severe CAP. The endpoints of the study included total mortality, length of intensive care unit (ICU) stay and mechanical ventilation. RESULTS Nine trials which contained 914 patients were included for final meta-analysis. Of the 488 patients in the corticosteroid group, there were 37 deaths (7.58%) and 56 deaths occurred in 426 patients in the control group (13.1%). Corticosteroid therapy was associated with a lower rate of all-cause mortality compared to control (odd ratio [OR] 0.63, 95% confidence interval [CI] 0.42-0.95, P = .03). Subgroup analysis was conducted to show that the drug type modified the effect of steroids for mortality rate: prednisolone or methylprednisolone therapy (OR 0.37, 95% CI 0.19-0.72) reduced total mortality, whereas hydrocortisone use did not (OR 0.90, 95% CI 0.54-1.49). We found the length of ICU stay was significantly shorter in the steroid group compared to control (MD -2.52 days, 95% CI -4.88 to -0.15; P = .04). And there was a reduction trend in the need for mechanical ventilation in corticosteroid group (OR 0.53, 95% CI 0.28-1.02; P = .06). There was no trend towards more adverse events in the corticosteroid arm compared to control (OR 0.92, 95% CI 0.58-1.47; P = .74). CONCLUSION Overall, adjunctive systemic corticosteroids therapy was effective and safe for patients with severe CAP. In addition, the effects of mortality may differ according to the type of corticosteroids.

Abstract
BACKGROUND Antimicrobial resistance in Mycoplasma genitalium is rising globally with resultant clinical treatment failure. We investigated the prevalence of mutations in the macrolide and fluoroquinolone resistance-determining regions of M. genitalium in Johannesburg, South Africa, and ascertained their association with HIV serostatus. METHODS Stored M. genitalium positive specimens, collected from STI and HIV patients enrolled in the Gauteng STI National Microbiological Surveillance programme (2007-2014) and a large HIV outpatient clinic-based study (2007) in Johannesburg, were tested for antimicrobial resistance. RESULTS We determined the prevalence of 23S rRNA gene mutations conferring macrolide resistance and mutations in the quinolone resistance-determining regions (QRDR) of the gyrA and parC genes in 266 M. genitalium positive DNA extracts. No macrolide resistance-associated mutations were detected in any of the specimens analysed. QRDR mutations with known M. genitalium-associated fluoroquinolone resistance were not detected in gyrA, however, one specimen (0.4%) contained a D87Y amino acid alteration in parC, which has been linked to fluoroquinolone treatment failure. The most common parC amino acid change detected, of unknown clinical significance, was P62S (18.8%). We found no significant association between QRDR mutations in M. genitalium and HIV-infection. CONCLUSIONS Ongoing antimicrobial resistance surveillance in M. genitalium is essential, as macrolide resistance may emerge given the recent incorporation of azithromycin into the 2015 South African national STI syndromic management guidelines.

Abstract
Pneumonia is a leading cause of death worldwide, ranking third both globally and in Taiwan. This guideline was prepared by the 2017 Guidelines Recommendations for Evidence-based Antimicrobial agents use in Taiwan (GREAT) working group, formed under the auspices of the Infectious Diseases Society of Taiwan (IDST). A consensus meeting was held jointly by the IDST, Taiwan Society of Pulmonary and Critical Care Medicine (TSPCCM), the Medical Foundation in Memory of Dr. Deh-Lin Cheng, the Foundation of Professor Wei-Chuan Hsieh for Infectious Diseases Research and Education and CY Lee's Research Foundation for Pediatric Infectious Diseases and Vaccines. The final guideline was endorsed by the IDST and TSPCCM. The major differences between this guideline and the 2007 version include the following: the use of GRADE methodology for the evaluation of available evidence whenever applicable, the specific inclusion of healthcare-associated pneumonia as a category due to the unique medical system in Taiwan and inclusion of recommendations for treatment of pediatric pneumonia. This guideline includes the epidemiology and recommendations of antimicrobial treatment of community-acquired pneumonia, hospital-acquired pneumonia, ventilator-associated pneumonia, healthcare-associated pneumonia in adults and pediatric pneumonia.

Abstract
Lower respiratory tract infections are the leading cause of infectious disease deaths worldwide and are the fifth leading cause of death overall. This is despite conditions such as pneumococcal infections and influenza being largely preventable with the use of appropriate vaccines. The mainstay of treatment for the most important bacterial lower respiratory tract infections, namely acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and community-acquired pneumonia (CAP), is the use of antibiotics. Yet despite a number of recent publications, including clinical studies as well as several systematic literature reviews and meta-analyses, there is considerable ongoing controversy as to what the most appropriate antibiotics are for the empiric therapy of CAP in the different settings (outpatient, inpatient, and intensive care unit). Furthermore, in the case of AECOPD, there is a need for consideration of which of these exacerbations actually need antibiotic treatment. This article describes these issues and makes suggestions for appropriately managing these conditions, in the setting of the need for antimicrobial stewardship initiatives designed to slow current emerging rates of antibiotic resistance, while improving patient outcomes.

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.
