These recommendations allow the use of point-of-care testing (POCT) systems provided that they have sufficient analytical performance. The aim of our study was to evaluate in real life the feasibility and performance of using a high sensitivity cardiac troponin I POCT system assay (hs-cTnI, Atellica® VTLi, Siemens) compared to high sensitivity cardiac troponin T values (hs-cTnT, e602®, Roche) obtained for patients admitted to emergency department. Analytical verification showed a coefficient of variation below 10% for hs-cTnI. Comparison of both troponins was moderate (r = 0.7). The study included 117 patients with a median age of 65 years, 30% had renal failure and 36% presented with chest pain. In this study, the hs-cTnT value was, more often, higher than the 99th percentile than the hs-cTnl value, even for an age-adjusted 99th percentile hs-cTnT value. The concordance of the results was moderate (Cohen's Kappa: 0.54), age remaining the most important explanatory value of discordance. Only hs-cTnT had a predictive value for hospitalization. We did not observe any interpretation discrepancies for patients who had troponin kinetics. This study confirms the feasibility of using a POCT analyzer in the emergency department, provided that it performs high sensitivity troponin. However, some data are missing to be able to use it in the framework of rapid algorithm. Finally, the implementation of POCT requires collaboration between biologists and emergency physicians in terms of organization and interpretation of values, for the overall benefit of the patient.","PeriodicalId":7892,"journal":{"name":"Annales de biologie clinique","volume":"81 2","pages":"145-155"},"PeriodicalIF":0.5,"publicationDate":"2023-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9483418","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}

In Europe, the majority of malaria cases come from travelers returning from endemic areas. The non-specific symptomatology may not alert the clinician if this notion of travel is not addressed. However, diagnosis and rapid initiation of treatment prevent the evolution of severe forms of the disease, especially in the case of Plasmodium falciparum infection, which can be life-threatening within 24 hours. Thin and thick blood smears microscopy is the main tools for diagnosis, but some automated hematology analyzers have demonstrated their ability to participate in early diagnosis. We describe two cases illustrating the contribution of the Sysmex XN-9100 automated system for the diagnosis of malaria. The first clinical case described a young man infected with numerous Plasmodium falciparum gametocytes. WNR (white blood cell count) and WDF (white blood cell differenciation) scattergrams showed an additional population, corresponding to gametocytes. The second case focused on a man with neuromalaria and high Plasmodium falciparum parasitaemia. Parasitized red blood cells form an inconspicuous double population on the reticulocyte scattergram, located at the discrimination limit between mature red blood cells and reticulocytes. Scattergram abnormalities, which can be visualized in a few minutes, offer an anticipation of the diagnosis of malaria in comparison to thin and thick smears microscopy, that requiring considerable time and expertise.","PeriodicalId":7892,"journal":{"name":"Annales de biologie clinique","volume":"81 2","pages":"189-197"},"PeriodicalIF":0.5,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9482337","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}

However, such method is time consuming and requires well-trained staff. Here, to address this issue, we tested the Sysmex UF-4000 analyzer coupled to a UD10 module as an automated flow cytometry-digital particle imaging workflow to assess (i) the ability of the system to detect and identify the crystals species and (ii) the quality of the images provided by the UD-10 module (n = 40) for each urine sample analyzed. First, systematic analysis of 76 samples by POM and the UF-4000/UD-10 analyzer showed that only attentive examination of the 40 photos was able to confidently detect crystalluria-positive samples with no misses and thus serve to discriminate positive-test crystalluria from negative-test crystalluria. These first results were confirmed by sensitivity analysis and the negative predictive value calculated on 200 samples for the results provided by the UF-4000 (39% and 46%) and after examination of the 40 UD-10 photos (100% for the both values). Digital images can therefore serve to screen crystalluria without missing crystals. A part of samples were treated by POM whereas it was not necessary (positive predictive value: 78%). Finally, we compared the crystal identification performances of the Sysmex UF4000/UD10 workflow and the ‘gold standard’ POM method on 131 urine samples containing crystals. Only calcium oxalate dihydrate crystals were identified by the Sysmex UF-4000. A close examination of the digital photographs enabled exact identification of crystals in 84.7% of the samples, suggesting however that POM is still require as soon as crystals are observed on the photographs. We conclude that a SYSMEX UF-4000 coupled with a UD-10 module can be used in practice with close examination of the photographs to discriminate positive crystalluria from negative crystalluria.","PeriodicalId":7892,"journal":{"name":"Annales de biologie clinique","volume":"81 1","pages":"86-90"},"PeriodicalIF":0.5,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9172476","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}
