Facilitating the ethical sourcing of donor hematopoietic stem cells for cell and gene therapy research and development.

Aim: Unrelated stem cell donor registries (DRs) are increasingly engaging in the field of cell and gene therapy (CGT). This study aims to explore the values, concerns, needs and expectations of donors and members of the public on donating hematopoietic stem cells (HSCs) for CGT.Methods: Seven focus groups were conducted in 2019 with members of the public, prospective donors and donors on the Anthony Nolan DR in the UK.Results: Participants expressed concerns over increased frequency of donation and incidental findings and required more information on the type of research including the purpose and possible outcomes.Conclusion: Addressing donors' concerns, needs and expectations on donating cellular materials for CGT research and development is essential to maintaining the highest standards for donor care and safety within this rapidly emerging field.

This study aims to explore the values, concerns, needs and expectations of people who donate, or consider donating, their stem cells (cells that can develop into many different types of cells) for research that could lead to new medical treatments. We focused on the thoughts of these donors about providing their cells for use in cell and gene therapy (CGT) research, a field that is rapidly advancing but still forming its rules and ethical guidelines. In 2019, we conducted seven focus groups (FGs) with a total of 73 people in the UK. This included individuals who are registered as potential stem cell donors on the Anthony Nolan unrelated stem cell donor register (DR), those who have already donated stem cells and members of the general public. We explored their thoughts about their donated cells being used for research to develop new therapies rather than for direct treatment of patients. Questions during the FGs touched on topics such as the roles of various organizations in managing donated cells, the commercial use of these cells and where responsibilities lie in ensuring ethical practices. Participants expressed a strong desire for openness and clear communication regarding how their donated cells are used in research. They wanted to ensure that any use of their cells aligns with their personal values and the ethical standards of the organizations handling the donations. Participants expected DRs like Anthony Nolan to safeguard their interests and the ethical use of their cells. This study highlights that while donors are generally willing to contribute to advancements in CGT research, they need clear, understandable information about how their donations are used. This is crucial for maintaining their trust and willingness to donate. Overall, this study underscores the importance of ethical practices and donor engagement in the growing field of CGT, ensuring that donor contributions are respected and used responsibly.

Genetic literacy among primary care physicians in a resource-constrained setting.

BACKGROUND: Genetic literacy among primary healthcare providers is crucial for appropriate patient care with the advances in genetic and genomic medicine. Studies from high-income countries highlight the lack of knowledge in genetics and the need to develop curricula for continuing professional development of non-geneticists. Scarce data is available from resource-constrained countries in Middle East and North Africa. Lebanon is a small country in this region characterized by high rates of consanguinity and genetic disorders like several surrounding countries, such as Jordan, Syria, and Turkey. METHODS: The primary aim of this study assessed the genetic literacy, self-perceived and actual knowledge as well as practices among primary care providers in Lebanon. The secondary aim identified their educational needs and proposed evidence-based continuing education programs. A cross-sectional survey-based study, using a self-administered questionnaire, was conducted targeting physicians from Family Medicine, Obstetrics and Gynecology, and Pediatrics. The questionnaire was divided into five sections: demographics, familiarity with genetic tests, self-reported and actual knowledge, genetic practices, and educational needs. Statistics were performed using SPSS v24. The Chi-square test was used for independent variables. Differences between mean scores were measured using paired sample t-tests for groups of two levels and one-way ANOVA for more than two. Multiple linear regression was used to study the variables associated with the knowledge score while controlling for other variables. RESULTS: The survey included 123 physicians. They were mostly familiar with karyotype as first-tier genetic test. Although 38% perceived their knowledge as good, only 6% scored as such in knowledge assessment. A better knowledge score was observed in academic institutions as well as in urban settings (p<0.05). One third never ordered any genetic testing, mostly due to poor knowledge. Almost all (98%) were ready to attend continuing professional development sessions in genetics. CONCLUSION: Our findings show the need to improve genetic literacy among healthcare frontliners, focusing on remote regions and nonacademic centers in Lebanon, a model for other resource-constrained country in the Middle East and North Africa region. This study advances recommendations for evidence-based genetic continuing education programs and highlighted the role of that the few genetic specialists can play in their successful implementation.

Remuneration of donors for cell and gene therapies: an update on the principles and perspective of the World Marrow Donor Association.

The cell and gene therapy (CGT) sector has witnessed significant advancement over the past decade, the inception of advanced therapy medicinal products (ATMPs) being one of the most transformational. ATMPs treat serious medical conditions, in some cases providing curative therapy for seriously ill patients. There is interest in pivoting the ATMP development from autologous based treatments to allogenic, to offer faster and greater patient access that should ultimately reduce treatment costs. Consequently, starting material from allogenic donors is required, igniting ethical issues associated with financial gains and donor remuneration within CGT. The World Marrow Donor Association (WMDA) established the Cellular Therapy Committee to identify the role WMDA can play in safeguarding donors and patients in the CGT field. Here we review key ethical principles in relation to donating cellular material for the CGT field. We present the updated statement from WMDA on donor remuneration, which supports non-remuneration as the best way to ensure the safety and well-being of donors and patients alike. This is in line with the fundamental objective of the WMDA to maintain the health and safety of volunteer donors while ensuring high-quality stem cell products are available for all patients. We acknowledge that the CGT field is evolving at a rapid pace and there will be a need to review this position as new practices and applications come to pass.

Prospective donors' perspectives on hematopoietic cell donation for cell and gene therapy research and development.

Aim: To explore prospective donors' attitudes and perceptions toward donating hematopoietic stem cells (HSCs) for novel treatments research and development (R&D). Methods: A survey was launched by Anthony Nolan (AN) to assess prospective donors' willingness to donate HSCs for novel therapies R&D, and their degree of comfort with the AN collaborating with and receiving payment from external organizations. Results: Most participants (87%) were willing to donate for novel treatment R&D and were comfortable with AN collaborating with external organizations and receiving payment (91% and 80%, respectively). Conclusion: Results reveal an overall positive response toward donating HSCs for R&D. These findings can support stakeholders and policymakers in outlining donation practices that uphold donors' safety and welfare.

Recent interest in the development of cell-based novel treatments using stem cells from healthy donors as opposed to patients' own stem cells may place pressure on stem cell donor registries to adapt and provide donor stem cells to the cell and gene industry. Since stem cell donor registries were originally established to connect patients in need of stem cell transplantation with matched willing stem cell donors, this shift in practice might result in several implications. Therefore, Anthony Nolan (AN), an unrelated stem cell donor registry in the UK, launched a survey to explore the willingness of potential donors to donate stem cells for novel treatment research and development (R&D). The results show that most participants (87%) would be willing to donate stem cells for novel treatment research and development. Most participants were comfortable with AN collaborating with external organizations (91%) and receiving payment from these organizations (80%). Additionally, some participants provided written responses that explained their answers to the questions in the survey. While some participants had positive views on collaborations with external establishments, others had apprehensions over their donations leading to profiteering. Moreover, participants had concerns over their privacy, especially if external collaborations with pharmaceutical companies were to take place. Informed consent and transparency over the nature of collaborations could relieve some of the above-mentioned concerns. These findings can support stakeholders and policymakers in outlining donation practices that uphold donors' safety and welfare.

Clinical Significance of Breast Cancer Molecular Subtypes and Ki67 Expression as a Predictive Value for Pathological Complete Response following Neoadjuvant Chemotherapy: Experience from a Tertiary Care Center in Lebanon.

INTRODUCTION: Breast cancer is considered nowadays the most prevalent cancer worldwide. The molecular era has successfully divided breast cancer into subtypes based on the various hormonal receptors. These molecular subtypes play a major role in determining the neoadjuvant chemotherapy to be administered. It was noted that the use of neoadjuvant chemotherapy was associated with higher achievement of pathological complete response. The aim of the study was to determine the predictive role of breast cancer subtypes in the efficacy and prognosis of neoadjuvant chemotherapy regimens. METHODS: Combining dose dense anthracycline-based, regular dose anthracycline-based, and nonanthracycline-based chemotherapy, we observed data from 87 patients with breast cancer who received surgery after administration of neoadjuvant chemotherapy at our institution between January 2015 and July 2018. The patients were classified into luminal A, luminal B, HER2 overexpression, and triple negative breast cancer as well as low Ki67 (≤14%) and high Ki67 (>14%) expression groups using immunohistochemistry. Pathologic complete response was the only neoadjuvant chemotherapy outcome parameter. To evaluate variables associated with pathologic complete response, we used univariate analyses followed by multivariate logistic regression. RESULTS: 87 patients with breast cancer were classified into different subtypes according to the 12th St. Gallen International Breast Cancer Conference. The response rate to neoadjuvant chemotherapy was significantly different (p = 0.046) between the subgroups. There were significant correlations between pathological complete response (pCR) and ER status (p < 0.0001), HER2 (p = 0.013), molecular subtypes (p = 0.018), T stage (p = 0.024), N stage before chemotherapy (p = 0.04), and type of chemotherapy (p = 0.029). Luminal B type patients had the lowest pCR, followed by luminal A type patients. CONCLUSION: Evaluating molecular subtype's significance in breast cancer prognosis warrants additional studies in our region with extensive data about patient-specific neoadjuvant chemotherapy regimens. Our study was able to reproduce results complementary to those present in the literature in other outcomes.

Molecular prevalence of eight different sexually transmitted infections in a Lebanese major tertiary care center: impact on public health.

BACKGROUND: Sexually transmitted diseases (STD) are caused by a variety of pathogens transmitted by sexual activity. Untreated infections can cause major complications with a substantial high cost on health sector. With the development of molecular techniques, STD screening became easier with a high sensitivity and specificity. OBJECTIVES: In Lebanon, official data regarding STD trends are scarce. This study elucidates the STD molecular profile at a tertiary care center, American University of Beirut Medical Center (AUBMC), its distribution among gender and age groups, with a comparison to international studies. METHODS: A retrospective data analysis was conducted on all STD panels performed at AUBMC from January 2017 till December 2019 to determine the molecular prevalence of eight different sexually transmitted organisms. RESULTS: Our samples belonged to 248 females (41.5%) and 349 males (58.5%). Only 53.5% of the samples tested positive for one or more organisms. Ureaplasma urealyticum/parvum was found to be the most common pathogen (49.3%), followed by Gardenerella vaginalis (33.5%), Chlamydia trachomatis (5.36%), Mycoplasma genitalium (5.16%), Neisseria gonorrhea (2.5%), Herpes simplex virus (2.5%), and Trichomonas vaginalis (1.39%). Age was distributed between 5 and 80 years old. Regarding the pathogen's distribution among gender, Ureaplasma urealyticum/parvum, Herpes simplex virus, and Gardenerella vaginalis were more common in females, the rest was more detected in males. CONCLUSION: Data will be of great importance for clinicians, in terms of diagnosis and treatment. It will help adopting an evidence based STI control programs in Lebanon, and it is essential for future larger studies and sexual health awareness programs.

Recommended measures for the efficient care of patients with genetic disorders during the COVID-19 pandemic in low and middle income countries.

The coronavirus disease 2019 (COVID-19) emerged in early 2020 and since, has brought about tremendous cost to economies and healthcare systems universally. Reports of pediatric patients with inherited conditions and COVID-19 infections are emerging. Specific risks for morbidity and mortality that this pandemic carries for different categories of genetic disorders are still mostly unknown. Thus, there are no specific recommendations for the diagnosis, management, and treatment of patients with genetic disorders during the COVID-19 or other pandemics. Emerging publications, from Upper-Middle Income countries (UMIC), discuss the recent experiences of genetic centers in the continuity of care for patients with genetic disorders in the context of this pandemic. Many measures to facilitate the plan to continuous genetic care in a well-developed health system, may not be applicable in Low and Middle Income countries (LMIC). With poorly structured health systems and with the lack of established genetic services, the COVID-19 pandemic will easily exacerbate the access to care for patients with genetic disease in these countries. This article focuses on the unique challenges of providing genetic healthcare services during emergency situations in LMIC countries and provides practical preparations for this and other pandemic situations.

Mapping the Diverse Genetic Disorders and Rare Diseases Among the Syrian Population: Implications on Refugee Health and Health Services in Host Countries.

The aim of this systematic review is to provide physicians and researchers with a comprehensive list of reported genetic disorders in patients of Syrian origin-those who have become part of the largest displaced population globally-and to highlight the need to consider migrant population-based risk for the development of genetic disease control and prevention programs. This review was performed based on the 2015 PRISMA and the international prospective register of systematic reviews. The present review reports on a total of 166 genetic disorders (only 128 reported on OMIM) identified in the Syrian population. Of these disorders, 27% are endocrine-, nutritional- and metabolic-related diseases. Second to metabolic disorders are congenital malformations, deformations and chromosomal abnormalities. Diseases of the blood and the blood-forming organs accounted for 13% of the total genetic disorders. The majority of the genetic disorders reported in Syrian patients followed an autosomal recessive mode of inheritance. These findings are a reflection of the high rates of consanguineous marriages that favor the increase in incidence of these diseases. From the diseases that followed an autosomal recessive mode of inheritance, 22% are reported to be only present in Syria and other regional countries. Twelve of these genetic diseases were identified to be strictly diagnosed in individuals of Syrian origin. The present systematic review highlights the need to develop programs that target genetic disorders affecting Syrian migrants in host countries. These programs would have potential financial and economic benefits, as well as a positive impact on the physical and mental health of members of the Syrian refugee community and those of their host societies. In turn, this would decrease the burden on the health systems in host countries.
