A regionally based precision medicine implementation initiative in North Africa:The PerMediNA consortium.

Precision Medicine is being increasingly used in the developed world to improve health care. While several Precision Medicine (PM) initiatives have been launched worldwide, their implementations have proven to be more challenging particularly in low- and middle-income countries. To address this issue, the "Personalized Medicine in North Africa" initiative (PerMediNA) was launched in three North African countries namely Tunisia, Algeria and Morocco. PerMediNA is coordinated by Institut Pasteur de Tunis together with the French Ministry for Europe and Foreign Affairs, with the support of Institut Pasteur in France. The project is carried out along with Institut Pasteur d'Algérie and Institut Pasteur du Maroc in collaboration with national and international leading institutions in the field of PM including Institut Gustave Roussy in Paris. PerMediNA aims to assess the readiness level of PM implementation in North Africa, to strengthen PM infrastructure, to provide workforce training, to generate genomic data on North African populations, to implement cost effective, affordable and sustainable genetic testing for cancer patients and to inform policy makers on how to translate research knowledge into health products and services. Gender equity and involvement of young scientists in this implementation process are other key goals of the PerMediNA project. In this paper, we are describing PerMediNA as the first PM implementation initiative in North Africa. Such initiatives contribute significantly in shortening existing health disparities and inequities between developed and developing countries and accelerate access to innovative treatments for global health.

Assessment of the Association of Chlamydia e pneumoniae Infection with Lung Cancer in a Moroccan Patients' Cohort.

BACKGROUND: Chlamydia pneumoniae (C. pneumoniae) is a respiratory pathogen associated with chronic inflammatory and its detection in human lung cancer suggests its involvement in cancerogenesis. Our study aimed to evaluate the association between C. pneumoniae  infection and Lung Cancer disease in Moroccans patients and control cohorts, through a molecular investigation. METHODS: The study comprised 42 lung cancer patients and 43 healthy controls. All participants provided demographics, Clinical, and Toxic behaviors datas, and a peripheral blood sample for testing, a Nested Polymerase Chain Reaction (PCR) was performed for C. pneumoniae Deoxyribonucleic acid (DNA) detection. Statistical analysis was performed using IBM®SPSS®software. RESULTS: Positive Nested PCR results for cases and controls were respectively 33.3% and 4.7%, there by  significant difference between cases and controls   infection was identified (p <0.05). Data analysis also showed that tobacco could act synergically with C. pneumoniae infection as a risk factor of lung cancer. In fact a significant difference between patients and controls was shown for tobacco and alcohol use (p < 0.05). CONCLUSION: C. pneumoniae infection is potentially associated with primary Lung cancer in the Moroccan population and has combined effects with Tabaco consumption.

Investigation of Chlamydia pneumoniae infection in Moroccan patients suffering from cardiovascular diseases.

Chlamydia pneumoniae is an intracellular bacterium responsible for respiratory diseases and is highly involved in cardiovascular disease development, mainly atherosclerosis. The main objective of our study was to evaluate C. pneumoniae prevalence in Moroccan patients suffering from cardiovascular diseases. A total of 115 patients with cardiovascular diseases were enrolled, and their clinical and behavioral information was recorded. Blood was sampled from all patients as well as the atheroma plaques from 36 patients undergoing surgery. Nested PCR was performed for C. pneumoniae DNA detection in both peripheral blood mononuclear cells (PBMCs) and atheroma plaques. Statistical analysis was performed using EpiInfo software. Data analysis showed cardiovascular disease dominance in men, with a sex ratio M/F of 3.4, a majority of tobacco users (52.2%), and many diabetics (44.3%). A significant difference between genders was shown for tobacco use (p<0.05). Positive cases for PBMCs and atheroma plaques were 61% and 86%, respectively, and a significant difference between PBMCs and atheroma plaque infection was identified (p=0.02). Data analysis also showed that 12% of patients presented only C. pneumoniae infection as a risk factor. Therefore, the high prevalence of C. pneumoniae suggests its involvement in atherosclerosis, and further investigation is recommended for confirmation.
