Soriano-Martín A, Alonso R, Machado M, Reigadas E, Muñoz P, Bouza E. Candida spp.: the burden of a microorganism in a microbiology department. Microbiol Spectr 2024; 12:e0386023. [PMID: 38980031 PMCID: PMC11302065 DOI: 10.1128/spectrum.03860-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Accepted: 06/04/2024] [Indexed: 07/10/2024] Open
Abstract
There is no precise information available on the entire workload of isolating a specific microorganism in a clinical microbiology laboratory, and the costs associated with it have not been specifically estimated. In this descriptive retrospective study conducted at the microbiology department of a general teaching hospital from January 2021 to December 2022, we assessed the workload associated with identifying Candida species in all types of clinical samples and patients. Costs were estimated from data obtained from the hospital's finance department and microbiology laboratory cost records. In 2 years, 1,008,231 samples were processed at our microbiology department, of which 8,775 had one or more Candida spp. isolates (9,683 total isolates). Overall, 5,151 samples with Candida spp. were identified from 2,383 inpatients. We isolated Candida spp. from 515.3 samples/100,000 population/year and from 92 samples/1,000 hospital admissions/year. By sample type, 90.8% were superficial, mainly mucosal. Only 9.1% Candida spp. were isolated from deep, usually sterile, samples, being mostly from ordinarily sterile fluids. Candida albicans was the main species (58.5%) identified, followed by C. parapsilosis complex, C. glabrata, C. tropicalis, and C. krusei. In admitted patients, the incidences of samples with Candida spp. isolates were 302.7 samples/100,000 population/year and 54 samples/1,000 admissions/year. The average cost of isolating and identifying Candida spp. was estimated at 25€ per culture-positive sample. To our knowledge, this is the first attempt to gage the workload and costs of Candida spp. isolation at a hospital microbiology department. These data can help assess the burden and significance of Candida isolation at other institutions and also help design measures for streamlining. IMPORTANCE We believe that this work is of interest because at present, there is no really accurate information available on the total workload involved in isolating a specific microorganism in a clinical microbiology laboratory. The costs related to this have also not been described. We have described the unrestricted workload of Candida spp. in all types of samples for all types of species and patients. We believe that this information would be necessary to collect and share this information as well as to collect it in a standardized way to know the current situation of Candida spp. workload in all clinical microbiology laboratories.

Fuady A, Setiawan D, Man I, de Kok IMCM, Baussano I. Toward a Framework to Assess the Financial and Economic Burden of Cervical Cancer in Low- and Middle-Income Countries: A Systematic Review. JCO Glob Oncol 2024; 10:e2400066. [PMID: 39116362 DOI: 10.1200/go.24.00066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 05/02/2024] [Accepted: 06/11/2024] [Indexed: 08/10/2024] Open
Abstract
PURPOSE To review the economic burden assessment of cervical cancer in low- and middle-income countries (LMICs) and use the findings to develop a pragmatic, standardized framework for such assessment. METHODS We first systematically reviewed articles indexed in scientific databases reporting the methodology for collecting and calculating costs related to the cervical cancer burden in LMICs. Data on study design, costing approach, cost perspective, costing period, and cost type (direct medical costs [DMC], direct nonmedical costs [DNMC], and indirect costs [IC]) were extracted. Finally, we summarized the reported limitations in the methodology and used the solutions to inform our framework. RESULTS Cervical cancer treatment costs across LMICs vary greatly and can be extremely expensive, up to 70,968 International US dollars. Economic and financial assessment methods also vary greatly across countries. Of the 28 reviewed articles, 25 studies reported DMC for cervical cancer treatment by extracting cost information from billing or insurance databases (eight studies), conducting surveys (five), and estimating the costs (12). Only 11 studies-mainly through surveys-reported DNMC and IC. The economic burden assessment framework includes health care/payer and societal perspectives (DMC, DNMC, IC, and human capital loss) across the cervical cancer screening and treatment continuum. To assess health care/payer costs, we recommend combining the predefined treatment standards with actual local treatment practices, multiplied by unit costs. To assess societal costs, we recommend conducting a cost survey in line with a standardized yet adaptable protocol. CONCLUSION Our standardized, pragmatic framework allows assessment of economic and financial burden of cervical cancer in LMICs despite the different levels of available resources across countries. This framework will facilitate global comparisons and monitoring and may also be applied to other cancers.

Cost-Effectiveness of Bivalent, Quadrivalent, and Nonavalent HPV Vaccination in South Africa. Clin Drug Investig 2022; 42:333-343. [PMID: 35294726 PMCID: PMC8989937 DOI: 10.1007/s40261-022-01138-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/23/2022] [Indexed: 12/31/2022]
Abstract
BACKGROUND AND OBJECTIVES In South Africa, the prevalence of human papillomavirus (HPV) and associated diseases, such as cervical cancer and genital warts, is among the highest in the world. This study evaluates the cost-effectiveness of bivalent, quadrivalent, and nonavalent HPV vaccination for 9- to 14-year-old girls from the South African healthcare system perspective. METHODS A Markov model portraying the natural HPV disease progression from high-risk infection to cervical intraepithelial neoplasia (CIN) I, CIN II/III, or cervical cancer and from low-risk infection to genital warts was built. Transition probability, utility, and efficacy data were sourced from peer-reviewed literature. Vaccination costs were calculated based on the World Health Organization (WHO) guidelines. The model was populated with a cohort of 520,000 9-year-old girls to calculate incremental cost-effectiveness ratios (ICER) in South African Rand (R) per quality-adjusted life-years (QALYs) gained for each vaccination strategy. RESULTS All HPV vaccination strategies dominate the no vaccine strategy. Compared with the bivalent vaccine, the nonavalent strategy increases QALYs by 0.14 and costs by R1793 (ICER: R13,013 per QALY) per person, while the quadrivalent vaccination provides -0.02 incremental QALYs and R1748 costs (ICER: -R116,397 per QALY). Consequently, at the South African willingness-to-pay threshold of R23,630 per QALY, nonavalent vaccination is the preferred strategy, with a probability of 90.2%. Scenario analysis demonstrated that results are influenced by vaccine coverage, efficacy, and duration of efficacy. CONCLUSIONS The introduction of nonavalent for bivalent HPV vaccination is a cost-effective intervention in South Africa. HPV vaccination should be part of a multifaceted public health strategy entailing screening, condoms, and education of all stakeholders to reduce the significant burden of sexual transmitted diseases in South Africa. Sex-neutral and catch-up vaccinations are subjects for further research.

Abstract
Noncommunicable diseases and their risk factors are important for all aspects of outbreak preparedness and response, affecting a range of factors including host susceptibility, pathogen virulence, and health system capacity. This conceptual analysis has 2 objectives. First, we use the Haddon matrix paradigm to formulate a framework for assessing the relevance of noncommunicable diseases to health security efforts throughout all phases of the disaster life cycle: before, during, and after an event. Second, we build upon this framework to identify 6 technical action areas in global health security programs that are opportune integration points for global health security and noncommunicable disease objectives: surveillance, workforce development, laboratory systems, immunization, risk communication, and sustainable financing. We discuss approaches to integration with the goal of maximizing the reach of global health security where infectious disease threats and chronic disease burdens overlap.

Abstract
BACKGROUND Despite the well-documented information on cancer prevention and management, among noncommunicable diseases (NCDs), globally, cancer continues to be the second leading cause of morbidity and mortality with devastating economic consequences. The burden is disproportionately more among developing countries and the extent of evidence available on the economic consequences (direct and indirect costs) of cancer remains unknown in low-income countries particularly in the sub-Saharan region. Understanding the costs of illness is important to inform decision-making on setting up health care policies and informing economic evaluation of interventions. This study aims to map evidence on the distribution of the economic burden (direct and indirect costs) associated with prevention, diagnosis, and treatment of three predominant cancers: prostate, cervix, and female breast in the sub-Saharan Africa. METHODS This scoping review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR), and will be conducted following Arksey and O'Malley's framework. We will search PubMed/MEDLINE, Web of Science, CINHAL (via EBSCOhost platform), Science Direct, Cochrane Database of Systematic Reviews, Africa-Wide Information, Google Scholar, and WHO Library. We will perform hand-searching of the reference lists of included studies and other relevant documents. Two reviewers will independently screen all citations, full-text articles, and abstract data. We will include primary studies from all study designs reporting costs associated with prevention, diagnosis and treatment of prostate, cervical, and breast cancers in the sub-Saharan region. Data analysis will involve quantitative (e.g., frequencies) and qualitative (e.g., thematic analysis) methods. A narrative summary of findings will be presented. DISCUSSION This review will map the extent of information available on the economic burden (direct and indirect costs) of prostate, cervical, and breast cancers in the sub-Saharan region. Further guidance for future research in the subject area will be discussed. SYSTEMATIC REVIEW REGISTRATION Open Science Framework.

Abstract
Background Cervical cancer imposes considerable economic burden on societies and individuals. There is lack of evidence regarding this from the developing world and particularly from sub-Saharan Africa. Therefore, the study aimed to estimate the societal costs of cervical cancer in Eswatini. Materials and methods The cost of illness study (CoI) was applied using national specific clinical and registry data from hospitals, registries and reports to determine the prevalence of cervical intraepithelial neoplasia (CIN) and cervical cancer in Eswatini in 2018. Cost data included direct medical costs (health care utilization in inpatient and outpatient care), direct non-medical costs (patient costs for traveling) and indirect costs based on productivity loss due to morbidity (patient time during diagnosis and treatment) and premature mortality. Results The estimated total annual cost for cervical cancer was $19 million (ranging between $14 million and $24 million estimated with lower and upper bounds). Direct cost represented the majority of the costs at 72% ($13.7 million) out of which total pre-cancerous treatment costs accounted for 0.7% ($94,161). The management of invasive cervical cancer was the main cost driver with costs attributable to treatment for FIGO III and FIGO IV representing $1.7 million and $8.7 million respectively. Indirect costs contributed 27% ($5.3 million) out of which productivity loss due to premature mortality represented the majority at 67% ($3.5 million). Conclusion The economic burden of cervical cancer in Eswatini is substantial. National public health prevention strategies with prophylactic HPV vaccine and screening for cervical lesions should therefore be prioritized to limit the extensive costs associated with cervical cancer.

Abstract
Diagnosed in more than 90% of cervical cancers, the fourth deadliest cancer in women, human papillomavirus (HPV) is currently the most common pathogen responsible for female cancers. Moreover, HPV infection is associated with many other diseases, including cutaneous and anogenital warts, and genital and upper aerodigestive tract cancers. The incidence and prevalence of these pathologies vary considerably depending on factors including HPV genotype, regional conditions, the study population, and the anatomical site sampled. Recently, features of the cervicovaginal microbiota are found to be associated with the incidence of HPV-related diseases, presenting a novel approach to identify high-risk women through both blood and cervical samples. Overall, the HPV repartition data show that HPV infection and related diseases are more prevalent in developing countries. Moreover, the available (2-, 4-, and 9-valent) vaccines based on virus-like particles, despite their proven effectiveness and safety, present some limitations in terms of system development cost, transport cold chain, and oncogenic HPV variants. In addition, vaccination programs face some challenges, leading to a considerable burden of HPV infection and related diseases. Therefore, even though the new (9-valent) vaccine seems promising, next-generation vaccines as well as awareness programs associated with HPV vaccination and budget reinforcements for immunization are needed.

Abstract
INTRODUCTION Genital warts are caused by infection with human papillomavirus (HPV) and are associated with significant morbidity. Primary prevention of genital warts is possible through HPV vaccination, but vaccination rates remain low in the USA. When deciding to implement HPV vaccination programs, public health officials and policy makers rely on cost-effectiveness studies that accurately reflect costs associated with morbidity and mortality. However, previous information on the cost of treating genital warts was outdated. OBJECTIVES We estimated the mean direct medical care costs associated with genital warts in the USA. METHODS This was a retrospective case-control study of patients diagnosed with genital warts and matched controls. We used commercial healthcare claims data from 2011 through 2014 to estimate total 1- and 2-year costs from date of diagnosis. We used a generalized linear model to identify factors associated with monthly costs. RESULTS We identified 34,686 eligible cases of genital warts during the period 2011-2014. The first 2-year mean direct medical cost differences between cases and controls were US$6737 for the USA. Costs were significantly higher in the first 3 months following diagnosis and were higher among older individuals, women, those with co-morbidities or psychiatric illnesses, and those located in the south and southwest USA. CONCLUSIONS The mean direct cost of treating genital warts is approximately US$6700 in the first 2 years after diagnosis in the USA. These data can assist policy makers in decisions with respect to allocation of resources to implement HPV vaccine programs.

Abstract
BACKGROUND This prevalence-based, cost-of-illness study estimated the health care costs of human papillomavirus (HPV) infection-associated diseases in the era before the introduction of organized HPV vaccination for 12-year-old girls in 2016, South Korea. METHODS The claims data provided by the National Health Insurance Service was used to estimate the prevalence of HPV-associated diseases and their direct medical costs, including costs related to hospitalizations, outpatient visits, and medications. RESULTS A total of 1.3 million men and women used medical services for HPV-attributed diseases between 2002 and 2015. Among women, the most common diseases attributable to HPV were cervical dysplasia (64.4%), anogenital warts (12.9%), cervical carcinoma in situ (10.7%) and cervical cancer (2.6%), whereas anogenital warts (80.6%), benign neoplasms of larynx (14.3%), and anal cancers (8.9%) were most common among men. In 2015, the healthcare cost attributable to HPV was 124.9 million US dollars (USD) representing 69.0% of the annual cost of all HPV-associated diseases. At a cost of 75.1 million USD, cervical cancer contributed the largest economic burden in 2015 followed by cervical dysplasia (19.4 million USD) and cervical carcinoma in situ (10.7 million USD). These three conditions represented 58.2% of the total annual cost of all HPV-associated diseases, while 84.2% of the total annual cost was attributable to HPV. Annual health care costs increased from 42.6 million USD in 2002 to 180.9 million USD in 2015. CONCLUSION The healthcare costs associated with HPV-related diseases in Korea are substantial and increased between 2002 and 2015 mainly caused by increased number of patients. Expanding the target age for HPV vaccination of girls and introducing HPV vaccination for boys are possible ways of reducing the economic burden of HPV-associated disease and should be considered.

Development of a human papillomavirus type 6/11 vaccine candidate for the prevention of condyloma acuminatum. Vaccine 2018; 36:4927-4934. [PMID: 30037483 DOI: 10.1016/j.vaccine.2018.06.041] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2018] [Revised: 05/23/2018] [Accepted: 06/16/2018] [Indexed: 11/23/2022]
Abstract
Condyloma acuminatum (CA) represents a significant human papillomavirus (HPV) disease burden worldwide, resulting in substantial healthcare costs and loss of life quality in both genders. To address this problem, we tried to develop a bivalent HPV6/11 virus-like particle (VLP) vaccine targeting CA. HPV6/11 VLPs were generated in Hansenula polymorpha, and a disassembly and reassembly (D/R) treatment was further conducted to improve the stability and monodispersity of the VLPs. The HPV6/11 VLPs were identified by transmission electron microscopy (TEM), high performance liquid chromatography (HPLC), mass spectrum (MS) and dynamic light scattering (DLS), and were evaluated for their immunogenicity in both mice and cynomolgus monkeys. The results showed that the HPV6/11 L1 proteins were correctly expressed and assembled into HPV6/11 VLPs, and the HPV6/11 VLPs formulated with aluminum phosphate induced vigorous production of specific neutralizing antibodies against HPV6/11 VLPs in mice and cynomolgus monkeys. These data indicated that the Hansenula polymorpha-derived HPV6/11 VLPs could be formulated into a bivalent vaccine used in prevention of CA.
