Pulmonary embolism in young males and females in Germany: data from the federal statistical office

Sex Differences in the Massively Transfused Trauma Patient

INTRODUCTION

Recent studies have suggested the female hypercoaguable state may have a protective effect in trauma. However, whether this hypercoagulable profile confers a survival benefit in massively transfused trauma patients has yet to be determined. We hypothesized that females would have better outcomes than males after traumatic injury that required massive transfusion protocol (MTP).

PATIENTS AND METHODS

All trauma patients who underwent MTP at an urban, level 1, academic trauma center were reviewed from November 2007 to October 2018. Female MTP patients were compared to their male counterparts.

RESULTS

There were a total of 643 trauma patients undergoing MTP. Of these, 90 (13.8%) were female and 563 (86.2%) were male. Presenting blood pressure, heart rate, shock index, and injury severity score (ISS) were not significantly different. Overall mortality and incidence of venous thromboembolism were similar. Complication profile and hospital stay were similar. On logistic regression, female sex was not associated with survival (HR: 1.04, 95% CI: 0.56-1.92, P = 0.91). Variables associated with mortality included age (HR: 1.02, 95% CI: 1.05-1.09, P = 0.03) and ISS (HR: 1.07, 95% CI: 1.05-1.09, P < 0.001). Increasing Glascow Coma Scale was associated with survival (HR: 0.85, 95% CI: 0.82-0.89, P < 0.001). On subset analysis, premenopausal women (age < 50) did not have a survival advantage in comparison with similar aged males (HR: 0.68, 95% CI: 0.36-1.28, P = 0.24).

DISCUSSION

Sex differences in coagulation profile do not result in a survival advantage for females when MTP is required.

Patients with isolated pulmonary embolism in comparison to those with deep venous thrombosis. Differences in characteristics and clinical evolution

BACKGROUND

Patients with acute pulmonary embolism (PE) often have leg deep vein thrombosis (DVT); sometimes, however, a DVT is not detected (isolated PE, I-PE). We aimed at assessing the proportion of patients with I-PE, and their characteristics and clinical evolution compared to those with DVT with/without PE (DVT/PE).

METHODS

Among 3573 patients included in the START2-Register for a venous thromboembolic event, 2880 (80.6%) had DVT/PE, the remaining I-PE (19.4%).

RESULTS

Patients with I-PE were older [(≥75 years, OR 1.4 (95%CI 1.13-1.69)], and more frequently females [OR 1.4 (1.19-1.67)]. Young females (aged ≤ 50 years) with an index event occurring during hormonal contraception (HC), were more prevalent in I-PE [OR 1.96 (1.26-3.03)]. At multivariate analysis, age > 75 years, female sex, heart failure, cancer and use of HC were risk factors significantly associated with I-PE, whereas thrombophilic alterations were associated with DVT/PE. During a follow-up of 4504 years (during anticoagulation), the rate of bleeding events was 1.1% patient/years and 1.0% patient/years in I-PE and DVT/PE, respectively. Venous thromboembolic events were equally prevalent in DVT/PE or I-PE (1.94% vs 0.86%, ns), whereas arterial complications were more prevalent in the latter group (1.01% vs 0.28%, p = 0.008).

CONCLUSION

I-PE and DVT/PE have important differences. Older age, female sex, heart failure and cancer, were risk factors for I-PE; thrombophilic alterations were associated with DVT/PE. HC use was more frequent in the I-PE group. The prevalence of arterial complications was higher in patients with I-PE. Further studies, specifically designed on this issue, are warranted.

Venous thromboembolism in young adults: Findings from the RIETE registry

BACKGROUND

Little is known on the clinical characteristics, risk factors and outcomes during anticoagulation in young patients with acute venous thromboembolism (VTE).

METHODS

We used data from the RIETE (Registro Informatizado Enfermedad TromboEmbólica) registry to assess the clinical characteristics, risk factors and outcomes during anticoagulation in VTE patients aged 10-24 years. Data were separately analyzed according to initial presentation and gender.

RESULTS

Of 76,719 patients with VTE, 1571 (2.0%) were aged 10-24 years. Of these, 989 (63%) were women and 669 (43%) presented with pulmonary embolism (PE). Most women were using estrogens (680, 69%) or were pregnant (101, 10%), while 59% of men had unprovoked VTE. Women were more likely to present with PE (48% vs. 34%). The majority (87%) of PE patients had Sat O₂ levels ≥90% at baseline. The vast majority (97%) of PE patients were at low risk according to the PESI score, many (90%) at very low risk. During the course of anticoagulation (median, 192 days), 40 patients had VTE recurrences, 17 had major bleeding and 10 died (3 died of PE). Women had as many VTE recurrences as major bleeds (15 vs. 14 events), while men had many more VTE recurrences than major bleeding (25 vs. 3 events).

CONCLUSIONS

VTE is associated with low risk of short-term mortality in young adults. Noticeable gender differences exist in the risk factor profile and the risk of VTE recurrences and major bleeding in the course of anticoagulation.

Pulmonary embolism in young people

Ziele: Es gibt eine anhaltende Diskussion über die Auswirkungen der hormonalen Kon-trazeption auf die Inzidenz von venösen Thromboembolien (VTE) bei jungen Frauen. Spezifische Daten für die Größe des Problems und ihre Veränderungen in den letzten Jahren in Deutschland sind nicht verfügbar. Daher untersuchten wir die Häufigkeit von VTE bei hospitalisierten jungen Menschen und analysierten geschlechtsspezifische Unterschiede.

Patienten und Methoden: Detaillierte Listen aller Lungenembolien (LE), kodiert als I26, und tiefer Venenthrombosen (TVT), kodiert als I80, bei Patienten im Alter von 10 bis 39 Jahre, die in den Jahren 2005 bis 2011 ins Krankenhaus eingeliefert worden waren, stellte das Statistische Bundesamt zur Verfügung.

Ergebnisse: Beginnend im Alter von 12–13 Jahren wurde für Frauen im Vergleich zu Männern eine höhere Anzahl von LE und TVT als Hauptdiagnose dokumentiert. Dieser geschlechtsspezifische Unterschied verschwindet im Alter von 32–33 Jahren. Dieser Unterschied in der Gesamtzahl der LE als Hauptdiagnose zwischen Männern und Frau-en innerhalb dieses Lebensabschnitts von 20 Jahre erhöhte sich von 318 in 2005 auf 606 im Jahr 2010 und sank auf 505 im Jahr 2011. Die Differenzierung in LE mit und ohne akutes cor pulmonale zeigte insbesondere eine spezifische Erhöhung der LE ohne akutes cor pulmonale bei jungen Frauen innerhalb dieser sieben Jahre. Ähnliche Änderungen konnten nicht für TVT als Hauptdiagnose gezeigt werden.

Schlussfolgerung: Die präsentierten Daten aus der deutschen DRG-Statistik zeigen einen dysproportional höheren Anstieg der Hospitalisierung junger Frauen mit Lungenembolie als Hauptdiagnose in den vergangenen Jahren. Die möglichen Ursachen der hormonalen Kon-trazeption für diesen Anstieg müssen weiter aufgeklärt werden.

Thrombosis: A major contributor to global disease burden

Thrombosis is a common pathology underlying ischaemic heart disease, ischaemic stroke, and venous thromboembolism (VTE). The Global Burden of Disease Study 2010 (GBD 2010) documented that ischaemic heart disease and stroke collectively caused one in four deaths worldwide. GBD 2010 did not report data for VTE as a cause of death and disability. We performed a systematic review of the literature on the global disease burden due to VTE in low, middle and high income countries. Studies from Western Europe, North America, Australia, and Southern Latin America (Argentina) yielded consistent results with annual incidences ranging from 0.75 to 2.69 per 1,000 individuals in the population. The incidence increased to between 2 and 7 per 1,000 among those 70 years of age or more. Although the incidence is lower in individuals of Chinese and Korean ethnicity, their disease burden is not low because of population aging. VTE associated with hospitalisation was the leading cause of disability-adjusted-lifeyears (DALYs) lost in low and middle income countries, and second in high income countries, responsible for more DALYs lost than nosocomial pneumonia, catheter-related blood stream infections, and adverse drug events. VTE causes a major burden of disease across low, middle, and high income countries. More detailed data on the global burden of VTE should be obtained to inform policy and resource allocation in health systems, and to evaluate if improved utilisation of preventive measures will reduce the burden.

Duration of anticoagulation after isolated pulmonary embolism

In the D-dimer and ULtrasonography in Combination Italian Study (DULCIS), serial D-dimer measurement in combination with assessment of residual thrombosis (in patients with deep vein thrombosis (DVT)) identified patients who safely discontinued anticoagulation after an unprovoked venous thromboembolism (VTE).

In this subgroup analysis, the value of D-dimer tests was assessed in patients with isolated pulmonary embolism (PE) compared with those with DVT, with or without PE (DVT/PE). The DULCIS database was reanalysed in relation to this target.

26.8% of the DULCIS patients had isolated PE as the index event; this was more prevalent in females (34.1%) than in males (21.1%; p<0.0001). The rate of positive D-dimer was similar in isolated PE and DVT/PE. The rate of recurrences was not different in isolated PE or DVT/PE patients (4.8% ppy versus 3.8% ppy; nonsignificant) who stopped anticoagulation for negative D-dimer, but it was markedly high (11.2% ppy; p<0.0001) in those with isolated PE who remained without anticoagulation despite positive D-dimer. Recurrences were more frequently new isolated PE in patients with isolated PE than with DVT/PE (six (46.2%) out of 13 versus two (7.4%) out of 27; p=0.0085).

Serial D-dimer assessment can inform on the risk of recurrent VTE and help determine the duration of anticoagulation in patients with isolated PE.

Thrombosis: a major contributor to global disease burden

BACKGROUND

Thrombosis is the common pathology underlying ischemic heart disease, ischemic stroke, and venous thromboembolism (VTE). The Global Burden of Disease Study 2010 (GBD 2010) documented that ischemic heart disease and stroke collectively caused 1 in 4 deaths worldwide. GBD 2010 did not report data for VTE as a cause of death and disability.

OBJECTIVE

To review the literature on the global burden of disease caused by VTE.

APPROACH AND RESULTS

We performed a systematic review of the literature on the global disease burden because of VTE in low-, middle-, and high-income countries. Studies from Western Europe, North America, Australia, and Southern Latin America (Argentina) yielded consistent results with annual incidences ranging from 0.75 to 2.69 per 1000 individuals in the population. The incidence increased to between 2 and 7 per 1000 among those aged ≥70 years. Although the incidence is lower in individuals of Chinese and Korean ethnicity, their disease burden is not low because of population aging. VTE associated with hospitalization was the leading cause of disability-adjusted life-years lost in low- and middle-income countries, and second in high-income countries, responsible for more disability-adjusted life-years lost than nosocomial pneumonia, catheter-related blood stream infections, and adverse drug events.

CONCLUSIONS

VTE causes a major burden of disease across low-, middle-, and high-income countries. More detailed data on the global burden of VTE should be obtained to inform policy and resource allocation in health systems and to evaluate whether improved use of preventive measures will reduce the burden.
