Both undernutrition and malnutrition cause deficits in micronutrients, trace elements and vitamins necessary for various physiological functions and the appropriate functioning of the immune system. These deficiencies and infectious diseases often coexist, with complex interactions. An assessment of the micro-nutrient nutritional status of Covid-19 patients has not been at the center of priorities and recommendations, due to both the medical emergency and the absence of direct evidence and rapid effects of supplementation. Few recommendations have come from learned societies due to the lack of significant evidence of the effects of supplementation in positive patients and a need for robust studies. Essential trace elements and vitamins are necessary for the differentiation, activation and execution of many functions of immune cells, but their specific role has yet to be defined. This review article discusses in the context of Covid-19 the importance of micronutrients (selenium, copper, zinc, vitamins C, D, A and those of group B) in the host to tend towards an optimization of the immune response to infections. A nutritional balance remains the key word for achieving micronutrient homeostasis. Attention had to be paid to micronutrients in primary prevention, in the general population, in order to reduce the risk of impaired nutritional status in case of major health situations.","PeriodicalId":7892,"journal":{"name":"Annales de biologie clinique","volume":"80 4","pages":"319-331"},"PeriodicalIF":0.5,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33464970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of our study is to show the epidemiological, clinical, biological and therapeutic characteristics of hematological hypereosinophilia.Patients and methods: This is a retrospective study over a 4-year period (March 2017-March 2021) concerning 14 patients with hematological hypereosinophilia.Results: Fourteen patients were included (9 women and 5 men). The median age at diagnosis was 55 years. Hematological hypereosinophilia was mainly of clonal etiology. Clinical manifestations were either specific to hypereosinophilia, such as organ damage, or related to the etiology of hypereosinophilia, such as hepato-splenomegaly and lymphadenopathy. Moderate and severe forms were the most commonly reported. Several other quantitative and qualitative abnormalities of the blood picture were reported. Identification of the FIP1L1-PDGFRA fusion gene by molecular biology (RT-PCR) was positive in two patients. Imatinib was the main treatment for clonal forms.Conclusion: Hematological hypereosinophilia is a rare and complex pathology. Our study has confirmed this epidemiological, clinical, biological and therapeutic heterogeneity and has enabled us to realize the contribution of molecular biology in the diagnosis and the treatment of hypereosinophilia.","PeriodicalId":7892,"journal":{"name":"Annales de biologie clinique","volume":"80 4","pages":"355-362"},"PeriodicalIF":0.5,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33465472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a summary of feedbacks after 2 years of the pandemic. At the early stage of Covid-19, with regard to the regions surveyed, a common symptomatology with local zoonosis (dengue fever, zika, malaria, leptospirosis, etc.) complicates the diagnosis of Covid-19. At a more advanced stage, it is a question of managing an influx of patients suffering from acute respiratory distress syndrome. In this case, the biology is then simpler and delocalized medical biology devices have proven their effectiveness. As a result, ICU clinicians can better manage the frequent comorbidities encountered in these regions: obesity, diabetes, chronic renal failure, cardiovascular diseases.","PeriodicalId":7892,"journal":{"name":"Annales de biologie clinique","volume":"80 4","pages":"311-318"},"PeriodicalIF":0.5,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33465474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A serum ferritin measurement was performed for all patients. They were further classified either into a non-severe or a severe group based on their hospitalization in intense care unit (ICU) for mechanical ventilation or death.Results: Univariate analysis revealed a significant association between increased serum ferritin and CRP levels, obesity, CT scan lesions, pathological respiratory rate, decreased PaO2/FiO2 ratio, the NEWS-2 score and the severe (n = 59) vs the non-severe (n = 112) outcome of Covid-19 patients.

A new automated method using an immunoenzymatic (IE) assay based on a biochip array technology combines short turning around time and analytical performances close to chromatography in terms of positivity cut-off. The aim of our study was to compare IE versus IC and chromatography methods using urines samples from clinical cases. Seventy-two samples were analyzed by IC (amphetamines, opiates, benzodiazepines, THC, methadone, cocaine), IE and chromatography (previous classes plus opioids and cathinone). Immunochromatography results were read by at least 7 operators to assess reading subjectivity. Immunoenzymatic, IC, and chromatrography results were compared with each other. Chromatographic quantification was analyzed to understand discrepancies. Significant discrepancies (29-64%) were observed between IC and IE for most of the drug families investigated except for benzodiazepines, methadone and opiates. These discrepancies were not identified between IE and chromatography, except for some substances (28% to 67% discrepancies for buprenorphine, tramadol and oxycodone, 100% for cathinone). In contrast to IC, the performance of IE approached those of chromatography, except for some substances for which cross-reactions must be investigated. Reading discrepancies were frequent with IC (33% of samples) and made robust result output challenging. In conclusion, the Multistat® is an interesting method for first-line toxicological screening for laboratories without chromatography method.","PeriodicalId":7892,"journal":{"name":"Annales de biologie clinique","volume":"80 4","pages":"369-384"},"PeriodicalIF":0.5,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33464971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increased use of direct oral anticoagulants (DOAC) for the treatment of venous thromboembolism (VTE) is now a challenge for hematology laboratories for the diagnosis of APS. DOAC interfere with LAC screening and confirmation tests resulting in a risk of false positive results. To avoid these interferences, several solutions are suggested. Some of them rely on the use of DOAC-reversal systems (activated charcoal tablet, filter system) others on the use of reagents insensitive to DOAC presence in the sample. Detection of anti-phosphatidylserine/prothrombin antibodies may be helpful because they are strongly associated to the presence of LAC and are increasingly recognized as a useful tool in the diagnosis and prognosis of APS. Finally, positivity of LA in the setting of a viral infection is frequent and not specific to APS. During the Covid-19 pandemic, many patients developed arterial and VTE that could suggest testing for aPLs. The association between LAC and a risk of VTE or in-hospital mortality in hospitalized Covid-19 patients was not demonstrated. Moreover, aPLs do not persist after Covid-19. Currently, testing for aPLs in Covid-19 patients is not recommended.","PeriodicalId":7892,"journal":{"name":"Annales de biologie clinique","volume":"80 4","pages":"333-343"},"PeriodicalIF":0.5,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33464972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
