ObjectiveTo investigate the effect of individual donation-nucleic acid amplification test (ID-NAT) and minipool of 16 donations-NAT (P16-NAT) on the results of NAT of blood donors.Methods From February 2009 to June 2009,samples randomly collected from voluntary blood donors in Beijing were tested individually or in pooling of 16 donations by the PROCLEIX ULTRIO assay.For ID-NAT reactive samples with HBsAg,anti-HCV,or anti-HIV serologically unqualified,ID-NAT repeat reactive samples with serologically qualified,and P16-NAT reactive and followed resolution ID-NAT reactive samples,were performed for further discriminatory assays for HIV-1,samples and followed resolution ID-NAT reactive samples,were performed for further discriminatory assays for HBV,HCV and HIV-1discriminatory reagents.Samples which were HBV NAT + alone with serologically qualified were further quantified and confirmed of HBV DNA by Roche HBV quantitative PCR,analyzed by HBV serology and were diluted to simulate if they could be detected in P16-NAT.Results ( 1 ) Among 7613 samples tested by ID-NAT,26 were NAT positive,i.e.the ID-NAT positive rate was 0.34% ( 26/7613 ). ( 2 ) Among 1004 P16 samples from 16 064 blood donations,27 were NAT positive,i.e.the P16-NAT positive rate was 0.17% (27/16 064).(3)In serological qualified donations,ID-NAT yield rate (1 in 826,9/7438 ) was much higher than P16-NAT ( 1 in 7875,2/15 750) (x2 =11.880,P < 0.05 ).All these 9 ID-NAT positive and 2 P16-NAT positive donations were discriminated as HBV NAT positive.There were no HCV NAT yield or HIV NAT yield samples. (4) Dilution assay showed only 2 of the 9 (22.22% ) ID-NAT HBV yields were detected by P16-NAT.(5)Eight ID-NAT and 2 P16-NAT positive samples were quantified for HBV DNA and confirmed as HBV NAT yield,although the virus loads were very low:2 samples had HBV viral loads of 15 IU/ml and 472 IU/ml,6 samples < 12 IU/ml,and 2 could not be detected in the original samples while had < 12 IU/ml and 14.3 IU/ml in the 10 times concentrated samples.(6)Among 11 HBV NAT yield cases,3 (27.3% ) were possible HBV window-period donors with all HBV seromarkers negative,the other 8 (72.7% ) had occult HBV infections with anti-HBc or anti-HBe positive,however anti-HBc IgM negative.(7) The rate of initial P16-NAT reactive pools needed to be further tested by ID-NAT was 2.49%(25/1004).Initial P16-NAT reactive pools which caused by serologically qualified donations was 0.20%(2/1004).ConclusionsHBV NAT yield cases are detected at a higher frequency with ID-NAT than P16-NAT.In order to avoid samples with low viral loads would be undetected,NAT assay with high sensitivity should be selected and tested in minimized minipool donations or even with individual donation.

Objective To establish an inactivated viral particle-based ELISA for the detection of antibodies against Middle East respiratory syndrome coronavirus (MERS-CoV) in serum samples collected from a MERS-CoV associated case. Methods Serum samples were collected from 10 newborns and 40 healthy adults. A viral particle-based ELISA was established by using the inactivated MERS-CoV virions as antigen. The levels of IgM and IgG antibodies in the serum samples were detected by the established ELISA and the cut-off values for positive detection were determined. Then the inactivated MERS-CoV virion-based ELISA was used to detect the antibodies against MERS-CoV in 5 serum samples collected from the first im-ported MERS case in China. Results The cut-off values of IgM and IgG antibodies in serum samples for ELISA were determined to be A450 readings of 0. 32 and 0. 42, respectively. The titers of IgM and IgG anti-bodies in serum samples collected at early admission to hospital from the first imported MERS case in China were both 1 ︰ 40. Seroconversion occurred 2 weeks after his admission to hospital with the titers of IgM and IgG reaching to 1 ︰ 320. Conclusion The inactivated MERS-CoV virion-based ELISA was established successfully and could be used for the detection of serum antibodies (IgG and IgM) in MERS associated cases.

Objective:To explore the clinical characteristics and predictors of severe acute pancreatitis complicated with acute respiratory distress syndrome (SAP-ARDS).Methods:Clinical data of consecutive 313 SAP patients hospitalized from January 2000 to January 2020 in Peking Union Medical College Hospital, were retrospectively analyzed, including 258 cases with ARDS (ARDS group) and 55 cases without ARDS (non-ARDS group). According to the severity of ARDS, ARDS group were further divided into mild ARDS group (165 cases) and moderate to severe ARDS group (93 cases). Clinical symptoms, laboratory examination and imaging results, ICU admission time and clinical outcome, as well as the local and systemic complications, acute physiology and chronic health evaluation (APACHEⅡ) within 24 h after admission, bedside index for severity in acute pancreatitis (BISAP), CT severity index (CTSI), sequential organ failure assessment (SOFA) and quick sequenctial organ failure assessment(qSOFA) score were recorded. Univariate and multivariate logistic regression were performed to analyze independent risk factors of SAP complicated with moderate to severe ARDS. Receiver operating characteristics curves (ROC) was drawn to calculate area under the ROC curve (area under curve, AUC) and evaluate the performance of WBC and hsCRP in predicting SAP complicated with moderate to severe ARDS, and assess the performance of APACHEⅡ, BISAP, CTSI, SOFA and qSOFA scores in predicting SAP-ARDS endotracheal intubation.Results:The ICU length of stay and mortality rate of SAP-ARDS patients were significantly higher than those without ARDS [(8.3±11.6 day vs 5.7±7.7 day, 12.4% vs 3.6%, all P value <0.05)]. Univariate analysis showed that elevated WBC ( OR 4.52, 95% CI 1.64-12.4) and hsCRP ( OR 3.69, 95% CI 1.29-10.48) on admission were independent risk factors for moderate to severe ARDS with SAP. The AUC of WBC and hsCRP for predicting SAP with moderate to severe ARDS at admission were 0.651(95% CI 0.532-0.770) and 0.615 (95% CI 0.500-0.730), respectively. The predicted cut-off values (Cut-off values) were 17.5×10 9/L and 159 mg/L, respectively, and the sensitivity was 53.1% and 78.1%, the specificity was 78.1% and 48.4% respectively. The area under the ROC curve for APACHEⅡ, BISAP, CTSI, SOFA, and qSOFA score 24 h after admission in the early prediction of endotracheal intubation were 0.739 (95% CI 0.626-0.840), 0.705 (95% CI 0.602-0.809), 0.753 (95% CI 0.650-0.849 ), 0.737 (95% CI 0.615-0.836) and 0.663 (95% CI 0.570-0.794), and the optimum Cut-off values were 14 points, 3 points, 5 points, 7 points, 2 points, and the sensitivity and specificity for these predictors were 58.8% and 81.4%, 79.4% and 60.0%, 73.5% and 67.1%, 38.2% and 98.6%, 45.5% and 83.3%, respectively. Conclusions::Elevated blood WBC and hsCRP on admission were independent risk factors for moderate to severe ARDS in SAP. APACHEⅡ≥14, BISAP≥3, CTSI≥5, SOFA≥7, or qSOFA≥2 within the 24 h admission indictaed that the risk of SAP patients to receive endotracheal intubation was high.
