    Immunoreactive Trypsinogen in Infants Born to Women with Cystic Fibrosis Taking Elexacaftor-Tezacaftor-Ivacaftor
    (MDPI, 2023-02-21) Patel, Payal; Yeley, Jana; Brown, Cynthia; Wesson, Melissa; Lesko, Barbara G.; Slaven, James E.; Chmiel, James F.; Jain, Raksha; Sanders, Don B.; Medicine, School of Medicine
    Most people with cystic fibrosis (CF) are diagnosed following abnormal newborn screening (NBS), which begins with measurement of immunoreactive trypsinogen (IRT) values. A case report found low concentrations of IRT in an infant with CF exposed to the CF transmembrane conductance regulator (CFTR) modulator, elexacaftor–tezacaftor–ivacaftor (ETI), in utero. However, IRT values in infants born to mothers taking ETI have not been systematically assessed. We hypothesized that ETI-exposed infants have lower IRT values than newborns with CF, CFTR-related metabolic syndrome/CF screen positive, inconclusive diagnosis (CRMS/CFSPID), or CF carriers. IRT values were collected from infants born in Indiana between 1 January 2020, and 2 June 2022, with ≥1 CFTR mutation. IRT values were compared to infants born to mothers with CF taking ETI followed at our institution. Compared to infants identified with CF (n = 51), CRMS/CFSPID (n = 21), and CF carriers (n = 489), ETI-exposed infants (n = 19) had lower IRT values (p < 0.001). Infants with normal NBS results for CF had similar median (interquartile range) IRT values, 22.5 (16.8, 30.6) ng/mL, as ETI-exposed infants, 18.9 (15.2, 26.5). IRT values from ETI-exposed infants were lower than for infants with abnormal NBS for CF. We recommend that NBS programs consider performing CFTR variant analysis for all ETI-exposed infants.

    Systematic review and meta-analysis of outcomes in patients with suspected pulmonary embolism
    (American Society of Hematology, 2021-04-27) Patel, Parth; Patel, Payal; Bhatt, Meha; Braun, Cody; Begum, Housne; Nieuwlaat, Robby; Khatib, Rasha; Martins, Carolina C.; Zhang, Yuan; Etxeandia-Ikobaltzeta, Itziar; Varghese, Jamie; Alturkmani, Hani; Bahaj, Waled; Baig, Mariam; Kehar, Rohan; Mustafa, Ahmad; Ponnapureddy, Rakesh; Sethi, Anchal; Thomas, Merrill; Wooldridge, David; Lim, Wendy; Bates, Shannon M.; Lang, Eddy; Le Gal, Grégoire; Haramati, Linda B.; Kline, Jeffrey A.; Righini, Marc; Wiercioch, Wojtek; Schünemann, Holger; Mustafa, Reem A.; Emergency Medicine, School of Medicine
    Prompt evaluation and therapeutic intervention of suspected pulmonary embolism (PE) are of paramount importance for improvement in outcomes. We systematically reviewed outcomes in patients with suspected PE, including mortality, incidence of recurrent PE, major bleeding, intracranial hemorrhage, and postthrombotic sequelae. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase for eligible studies, reference lists of relevant reviews, registered trials, and relevant conference proceedings. We included 22 studies with 15 865 patients. Among patients who were diagnosed with PE and discharged with anticoagulation, 3-month follow-up revealed that all-cause mortality was 5.69% (91/1599; 95% confidence interval [CI], 4.56-6.83), mortality from PE was 1.19% (19/1597; 95% CI, 0.66-1.72), recurrent venous thromboembolism (VTE) occurred in 1.38% (22/1597; 95% CI: 0.81-1.95), and major bleeding occurred in 0.90% (2/221%; 95% CI, 0-2.15). In patients with a low pretest probability (PTP) and negative D-dimer, 3-month follow-up revealed mortality from PE was 0% (0/808) and incidence of VTE was 0.37% (4/1094; 95% CI: 0.007-0.72). In patients with intermediate PTP and negative D-dimer, 3-month follow-up revealed that mortality from PE was 0% (0/2747) and incidence of VTE was 0.46% (14/3015; 95% CI: 0.22-0.71). In patients with high PTP and negative computed tomography (CT) scan, 3-month follow-up revealed mortality from PE was 0% (0/651) and incidence of VTE was 0.84% (11/1302; 95% CI: 0.35-1.34). We further summarize outcomes evaluated by various diagnostic tests and diagnostic pathways (ie, D-dimer followed by CT scan).

    Systematic review and meta-analysis of test accuracy for the diagnosis of suspected pulmonary embolism
    (Silverchair, 2020-09-11) Patel, Parth; Patel, Payal; Bhatt, Meha; Braun, Cody; Begum, Housne; Wiercioch, Wojtek; Varghese, Jamie; Wooldridge, David; Alturkmani, Hani; Thomas, Merrill; Baig, Mariam; Bahaj, Waled; Khatib, Rasha; Kehar, Rohan; Ponnapureddy, Rakesh; Sethi, Anchal; Mustafa, Ahmad; Lim, Wendy; Le Gal, Grégoire; Bates, Shannon M.; Haramati, Linda B.; Kline, Jeffrey A.; Lang, Eddy; Righini, Marc; Kalot, Mohamad A.; Husainat, Nedaa M.; Jabiri, Yazan Nayif Al; Schünemann, Holger J.; Mustafa, Reem A.; Emergency Medicine, School of Medicine
    Pulmonary embolism (PE) is a common, potentially life-threatening yet treatable condition. Prompt diagnosis and expeditious therapeutic intervention is of paramount importance for optimal patient management. Our objective was to systematically review the accuracy of D-dimer assay, compression ultrasonography (CUS), computed tomography pulmonary angiography (CTPA), and ventilation-perfusion (V/Q) scanning for the diagnosis of suspected first and recurrent PE. We searched Cochrane Central, MEDLINE, and EMBASE for eligible studies, reference lists of relevant reviews, registered trials, and relevant conference proceedings. 2 investigators screened and abstracted data. Risk of bias was assessed using Quality Assessment of Diagnostic Accuracy Studies-2 and certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation framework. We pooled estimates of sensitivity and specificity. The review included 61 studies. The pooled estimates for D-dimer sensitivity and specificity were 0.97 (95% confidence interval [CI], 0.96-0.98) and 0.41 (95% CI, 0.36-0.46) respectively, whereas CTPA sensitivity and specificity were 0.94 (95% CI, 0.89-0.97) and 0.98 (95% CI, 0.97-0.99), respectively, and CUS sensitivity and specificity were 0.49 (95% CI, 0.31-0.66) and 0.96 (95% CI, 0.95-0.98), respectively. Three variations of pooled estimates for sensitivity and specificity of V/Q scan were carried out, based on interpretation of test results. D-dimer had the highest sensitivity when compared with imaging. CTPA and V/Q scans (high probability scan as a positive and low/non-diagnostic/normal scan as negative) both had the highest specificity. This systematic review was registered on PROSPERO as CRD42018084669.
