Contribution of genotypes in Prothrombin and Factor V Leiden to COVID-19 and disease severity in patients at high risk for hereditary thrombophilia.

Thrombotic and microangiopathic effects have been reported in COVID-19 patients. This study examined the contribution of the hereditary thrombophilia factors Prothrombin (FII) and Factor V Leiden (FVL) genotypes to the severity of COVID-19 disease and the development of thrombosis. This study investigated FII and FVL alleles in a cohort of 9508 patients (2606 male and 6902 female) with thrombophilia. It was observed that 930 of these patients had been infected by SARS-CoV-2 causing COVID-19. The demographic characteristics of the patients and their COVID-19 medical history were recorded. Detailed clinical manifestations were analyzed in a group of cases (n = 4092). This subgroup was age and gender-matched. FII and FVL frequency data of healthy populations without thrombophilia risk were obtained from Bursa Uludag University Medical Genetic Department's Exome Databank. The ratio of males (31.08%; 27.01%) and the mean age (36.85 ± 15.20; 33.89 ± 14.14) were higher among COVID-19 patients compared to non-COVID-19 patients. The prevalence of FVL and computerized tomography (CT) positivity in COVID-19 patients was statistically significant in the thrombotic subgroup (p < 0.05). FVL prevalence, CT positivity rate, history of thrombosis, and pulmonary thromboembolism complication were found to be higher in deceased COVID-19 patients (p < 0.05). Disease severity was mainly affected by FVL and not related to genotypes at the Prothrombin mutations. Overall, disease severity and development of thrombosis in COVID-19 are mainly affected by the variation within the FVL gene. Possible FVL mutation should be investigated in COVID-19 patients and appropriate treatment should be started earlier in FVL-positive patients.

Strong association between angiotensin-converting enzyme gene InDel polymorphism and COVID-19 diseases.

BACKGROUND AND OBJECTIVES: The COVID-19 pandemic that emerged in China in late 2019 and spread rapidly around the world. There is evidence that COVID-19 infection can be influenced by genetic variations in the host. The aim of this study was to investigate the association between ACE InDel polymorphism and COVID-19 in Northern Cyprus. PATIENTS AND METHODS: This study included 250 patients diagnosed with COVID-19 and 371 healthy controls. Genotyping for the ACE InDel gene polymorphism was performed by polymerase chain reaction. RESULTS: The frequency of ACE DD homozygotes was significantly increased in COVID-19 patients compared to the control group (p=0.022). The difference in the presence of the D allele between the patient and control groups was statistically significant (57.2% and 50.67%, respectively, p<0.05). Individuals with the genotype II were found to have a higher risk of symptomatic COVID-19 (p=0.011). In addition, chest radiographic findings were observed more frequently in individuals with the genotype DD compared to individuals with the genotypes ID and II (p=0.005). A statistically significant difference was found when the time of onset of symptoms for COVID-19 and duration of treatment were compared with participants' genotypes (p=0.016 and p=0.014, respectively). The time of onset of COVID-19 was shorter in individuals with the genotype DD than in individuals with the genotype II, while the duration of treatment was longer. CONCLUSION: In conclusion, the ACE I/D polymorphism has the potential to predict the severity of COVID-19.

Antecedentes y objetivos: La pandemia de COVID-19 surgió en China a fines de 2019 y se extendió rápidamente por todo el mundo. Existe evidencia de que la infección por COVID-19 puede verse influenciada por variaciones genéticas en el huésped. El objetivo de este estudio fue investigar la asociación entre el polimorfismo ACE InDel y COVID-19 en el norte de Chipre. Pacientes y métodos: Se incluyeron 250 pacientes diagnosticados de COVID-19 y 371 controles sanos. El genotipado del polimorfismo del gen ACE InDel se realizó mediante reacción en cadena de la polimerasa. Resultados: La frecuencia de homocigotos ACE DD aumentó significativamente en pacientes con COVID-19 en comparación con el grupo de control (p = 0,022). La diferencia en la presencia del alelo D entre los grupos de pacientes y control fue estadísticamente significativa (57,2% y 50,67%, respectivamente, p < 0,05). Las personas con el genotipo II tenían un mayor riesgo de COVID-19 sintomático (p = 0,011). Además, los hallazgos radiográficos de tórax se observaron con mayor frecuencia en individuos con el genotipo DD en comparación con los individuos con los genotipos ID y II (p = 0,005). Se encontró una diferencia estadísticamente significativa cuando se comparó el tiempo de aparición de los síntomas de COVID-19 y la duración del tratamiento con los genotipos de los participantes (p = 0,016 y p = 0,014, respectivamente). El tiempo de aparición de COVID-19 fue más corto en individuos con genotipo DD que en individuos con genotipo II, mientras que la duración del tratamiento fue más prolongada. Conclusiones: El polimorfismo ACE I/D podría predecir la gravedad de la COVID-19.

Periconceptional Mediterranean diet during pregnancy on children's health.

During pregnancy, rapid and subtle physiological changes are observed from conception to birth. Nutrition and other lifestyle factors before and during pregnancy have been shown in the literature to influence the health of both mother and child. A healthy and varied diet during pregnancy can provide adequate energy and nutrients for both the mother and the growing fetus. Current research focuses on the periconceptional phase, which includes the early processes of gametogenesis, embryogenesis and placentation. A variety of abnormalities and pregnancy-related problems occur during this period, including congenital defects, fetal loss, miscarriage and preterm birth. A varied and balanced diet during periconception is important to maintain fetal development and growth. To date, numerous studies have been conducted to investigate the effects of consuming different nutrients, foods or food groups during pregnancy on the health of mother and child. For example, the Mediterranean diet is considered as a balanced, nutrient-rich diet due to the low consumption of meat products and fatty foods and the high consumption of vegetables, cheese, olive oil, fish, shellfish and little meat. While many studies have been conducted in the literature to investigate the effects of a Mediterranean diet during pregnancy on fetal health, the results have been inconclusive. The aim of this article is to review the current literature on the Mediterranean diet during pregnancy.

Functional coding/non-coding variants in EGFR, ROS1 and ALK genes and their role in liquid biopsy as a personalized therapy.

Personalized medicine holds promise to tailor the treatment options for patients' unique genetic make-up, behavioral and environmental background. Liquid biopsy is non-invasive technique and precise diagnosis and treatment approach. Significantly, NGS technologies have revolutionized the genomic medicine by novel identifying SNPs, indel mutations in both coding and non-coding regions and also a promising technology to accelerate the early detection and finding new biomarkers for diagnosis and treatment. The number of the bioinformatics tools have been rapidly increasing with the aim of learning more about the detected mutations either they have a pathogenic role or not. EGFR, ROS1 and ALK genes are members of the RTK family. Until now, mutations within these genes have been associated with many cancers and involved in resistance formation to TKIs. This review article summarized the findings about the mostly investigated variations in EGFR, ROS1 and ALK genes and their potential role in liquid biopsy approach.
