Spontaneous pulmonary hematoma in patients with COVID-19.

The disease caused by Sars-Cov-2 (Covid-19) has become a worldwide pandemic and consequently a public health problem. Multiple complications associated with Covid-19 have been described, including coagulation abnormalities. Although the infection is known to induce a prothrombotic state, hemorrhagic complications have also been reported in patients with Covid-19, especially in anticoagulated patients. We present two cases of spontaneous pulmonary hematoma in patients with Covid-19 undergoing anticoagulant treatment. We aim to describe this complication, which although uncommon, should be taken into account in anticoagulated patients with Covid-19.

Hematoma pulmonar espontáneo en pacientes con COVID-19 / Spontaneous pulmonary hematoma in patients with COVID-19

La enfermedad causada por SARS-CoV-2 (Covid-19) se ha convertido en una pandemia mundial y en consecuencia en un problema de salud pública. Se han descrito múltiples complicaciones asociadas a la COVID-19, entre ellas alteraciones de la coagulación. Si bien es conocido que la infección induce un estado protrombótico, también se han descrito complicaciones hemorrágicas en estos pacientes, sobre todo en pacientes anticoagulados. Presentamos dos casos de hematoma pulmonar espontáneo en pacientes con neumonía COVID-19 y terapia anticoagulante. Nuestro objetivo es describir esta complicación, que, aunque poco frecuente, conviene tener en cuenta en pacientes anticoagulados y con COVID-19 concomitante (AU)

Influence of antithrombotic agents on recurrence rate and clinical outcome in patients operated for chronic subdural hematoma.

INTRODUCTION: Chronic subdural hematoma (cSDH) is a common pathology encountered in neurosurgical practice, especially in elderly patients, who frequently require antithrombotic agents. The aim of this study was to investigate the influence of antithrombotic agents on recurrence rates and clinical outcomes in patients operated for cSDH. METHODS: A cohort of patients operated for cSDH at one center during a 5 years period was analyzed retrospectively. Presenting symptoms, coagulation testing, history of antithrombotic agents and comorbidities were obtained from the patient charts. The standard neurosurgical procedure was a single burr hole under local anesthesia with insertion of a subdural drainage. Questionnaires and telephone interviews were used to assess the clinical outcome using the modified Rankin Scale (mRS). Good outcome was defined as mRS 0 to 3 and poor outcome as mRS 4 to 6. RESULTS: 201 patients with cSDH underwent initial surgical treatment and were enrolled in the study. The median follow-up was 81 weeks. 41 patients (20.4%) were on antiplatelet drug and 43 (21.4%) were on phenprocoumon. A recurrent hematoma required surgery in 37 patients (18.4%). A poor outcome was seen in 36 patients (17.9%). Each of older age and administration of phenprocoumon at admission was an independent risk factor predictive of poor outcome, (p=0.001 and p=0.031, respectively)) Administration of antithrombotic agents had no impact on hematoma recurrence. CONCLUSION: Administration of phenprocoumon and older age might increase the risk of poor outcome in patients with cSDH. Neither the administration of phenprocoumon nor antiplatelet drug influenced the recurrence rate of subdural hematoma in our patient cohort.

[Oral anticoagulation in atrial fibrillation: What is the guideline for using new drugs?] / Anticoagulación oral en la fibrilación auricular: ¿qué guía el uso de los nuevos fármacos?

OBJECTIVE: To assess whether there are differences between atrial fibrillation (AF) patients initiating new direct-acting oral anticoagulants (DOAC) therapy and vitamin K antagonist (VKA) therapy in an emergency service. METHODS: Descriptive, observational, prospective study. We enrolled patients with AF who were visited in a hospital emergency service over one year. RESULTS: This study included 492 patients with AF, and 189 subjects received anticoagulant therapy, 104 with VKA (55%), and 85 with DOAC (45%). The VKA group: mean age 76.1 years, male 50.9% and female 49.1%, CHA2DS2-VASc mean 3.2±1.3 points, and a HAS-BLED mean of 1.9±0.8 points. The DOAC group: mean age 73.4 years, male 37.6% and female 63.3%, CHA2DS2-VASc mean 3.1±1.6 points, and a HAS-BLED mean of 1.7±0.8 points. On analysing the medical history, 17.3% of patients in the VKA group had a previous stroke, and 13.5% significant valve disease, as well as 7.1 and 1.2% of patients, respectively, in the DOAC group. In the analysis of the DOAC types, 24.2% of patients in the dabigatran group had a previous stroke, 22.7% in the rivaroxaban group had ischaemic heart disease. CONCLUSIONS: Patients with AF who start on treatment in emergency services with VKA or with DOAC show a similar profile of age, gender, CHA2DS2-VASc score, and HAS-BLED score. The patients with a history of valvular or ischaemic heart disease received more VKA than DOAC. When the patient has a history of stroke, the DOAC more used is dabigatran, and in patients with ischaemic heart disease it is preferred to give rivaroxaban.

[Prevalence of oral anticoagulation and quality of its management in primary healthcare: A study by the Health Sentinel Network of the Region of Valencia (Spain)]. / Prevalencia de la anticoagulación oral y calidad de su seguimiento en el ámbito de la atención primaria: estudio de la Red Centinela Sanitaria de la Comunitat Valenciana.

OBJECTIVE: To estimate the prevalence of patients with oral anticoagulant therapy (OAT) in the Region of Valencia and to evaluate the quality of management of OAT with vitaminK antagonists (VKA) carried out in primary healthcare. DESIGN: Observational cross-sectional study conducted through the Health Sentinel Network of the Region of Valencia, which includes a survey and the retrospective analysis of OAT monitoring. SETTING: Primary healthcare, Region of Valencia, Spain. SUBJECTS: All patients aged 18years or older on OAT who consulted during the year 2014. The population covered by the 59 doctors of the Health Sentinel Network constitutes 2.2% of the adult population of the Region of Valencia, and it is representative of it. KEY MEASUREMENTS: Demographic, socioeconomic and health data as well as information concerning OAT. Quality of OAT management with VKA was assessed by means of the percentage of time in therapeutic range (TTR), computed using the Rosendaal method. RESULTS: A total of 1,144 patients were recorded (mean age 74.5±11 years; 49.7% women). Prevalence of OAT in the Region of Valencia is 1.3 cases per 100 population. The characteristic profile of these patients is an old person, with several comorbidities and a low level of education, who lives accompanied. Atrial fibrillation is the most common indication. 82.8% of patients on OAT with VKA were monitored in primary healthcare. The average TTR was 65.0%, and 53.9% of patients had a TTR ≥65%. Among inadequately controlled patients, 74.4% were perceived as well-controlled by their primary care doctor. CONCLUSIONS: Prevalence of OAT is high, and it is expected to increase. The degree of control achieved meets the generally accepted quality standard (mean TTR ≥65%), and it is comparable to that observed in other national and international studies. However, there is wide scope for improvement. It is crucial to optimize the management of this therapy in the most effective and cost-effective way. Among other measures, access of physicians to their patients' clinical information should be improved.
