RESUMO

Background and Objectives. COVID-19 infection has a significant burden on global morbidity and mortality, especially in elderly people and in patients with chronic respiratory and cardiovascular diseases, such as pulmonary hypertension (PH). We aimed to evaluate the impact of COVID-19 infection on patients diagnosed with severe chronic PH. Materials and Methods. A single-center prospective cohort study was performed. Patients were enrolled from 1 November 2020 to 31 December 2022. Follow-up was until 31 December 2023. Data were collected on PH diagnosis, clinical presentation, outcomes, brain natriuretic peptide (BNP) levels, pulmonary function test with lung diffusion capacity for carbon monoxide (DLCO), and computed tomography pulmonary angiography (CTPA) analysis. Results. During the 26 months of our study, 51 PH patients were diagnosed with COVID-19 infection. The majority, 44 (86.3%) of all COVID-19 infected patients, were treated on an outpatient basis, and 7 (13.7%) required hospitalization. During the follow-up period, 8 (15.7%) patients died: 4 (7.8%) due to complications of COVID-19 infection, and the other 4 (7.8%) died in the later stages of the follow-up period after recovery from acute COVID-19 infection. Therefore, the in-hospital mortality in our study was 43% (n = 3). As mentioned above, the overall mortality was 7.8% (n = 4). Higher BNP levels in the third month after COVID-19 were associated with higher mortality rates (p = 0.028). Lung function, including DLCO, did not significantly worsen with COVID-19. In our study, 24 patients (47.1%) were referred for a follow-up CTPA scan and one of them developed typical fibrotic lung changes after COVID-19. Conclusions. The incidence of COVID-19 infection in patients diagnosed with PH was 34%. In our patients with severe chronic PH, the overall mortality rate due to COVID-19 infection was low. Pulmonary fibrosis was a rare complication in our cohort. COVID-19 infection in severe PH may increase the risk of worsening chronic heart failure.

RESUMO

This study aimed to determine resistance to antimicrobials of Staphylococcus aureus strains isolated from clinical specimens in Lithuanian hospitals and to identify the genes conferring resistance and virulence. The study was carried out from June 2019 to September 2021. S. aureus strains were isolated from skin, soft tissues, blood, lower respiratory tract, urine and other specimens. Antibiotic susceptibility testing was performed using the disc diffusion method according to EUCAST guidelines. All isolates were analyzed for detection of the ermA, ermC, mecA, mecC, tetK, tetM, and lukF-PV genes by multiplex real-time PCR. The 16S rRNA coding sequence was applied as an internal PCR control. Altogether, 745 S. aureus strains were analyzed. Antimicrobial susceptibility testing revealed that all isolates were susceptible to rifampin and vancomycin. Of the 745 strains, 94.8% were susceptible to tetracycline, 94.5% to clindamycin, and 88.3% to erythromycin. The lowest susceptibility rate was found for penicillin (25.8%). Six percent of the tested strains were methicillin-resistant S. aureus (MRSA). The majority of methicillin-resistant strains were isolated from skin and soft tissues (73.3%), with a smaller portion isolated from blood (17.8%) and respiratory tract (8.9%). The ermC gene was detected in 41.1% of erythromycin-resistant S. aureus strains, whereas ermA was detected in 32.2% of erythromycin-resistant S. aureus strains. 69.2% of tetracycline-resistant S. aureus strains had tetK gene, and 28.2% had tetM gene. 7.3% of S. aureus isolates harbored lukF-PV gene. The frequency of the pvl gene detection was significantly higher in MRSA isolates than in methicillin-susceptible S. aureus isolates (p < 0.0001).

RESUMO

BACKGROUND: Infective endocarditis (IE) remains major cause of morbidity and mortality in adult congenital heart disease (ACHD). Limited data exists on ACHD with IE in Central and South-Eastern European (CESEE) countries. The aim of this study is to characterize contemporary management and assess outcomes of ACHD with IE in CESEE region. METHODS: Data on ACHD patients with IE from 9 tertiary centres in 9 different CESEE countries between 2015 and 2020 was included. Baseline demographics, clinical presentation, indication for surgery, outcomes, hospital and all-cause-1-year mortality were studied. RESULTS: A total of 295 ACHD patients (mean age 40 ± 14 years) with IE were included. Median time from symptoms onset to establishing diagnosis was 25 (11-59) days. The majority of patients (203, 68.8%) received previous empiric oral antibiotic therapy. The highest incidence of IE was observed on native and left sided valves, 194(65.8%) and 204(69.2%), respectively. More than half had a vegetation size ≥10 mm (164, 55.6%); overall 138 (46.8%) had valve complications and 119 (40.3%) had heart failure. In-hospital mortality was 26 (8.8%). CONCLUSION: There is clear delay in establishing IE diagnosis amongst ACHD patients in CESEE countries. Adequate diagnosis is hampered by common prescription of empiric antibiotics before establishing formal diagnosis. Hence, patients commonly present with associated complications requiring surgery. Hospital treatment and survival are, nevertheless, comparable to other Western European countries. Improved awareness and education of patients and medical profession regarding IE preventive measures, risks, signs, and symptoms are urgently needed. Empiric antibiotic prescription before blood cultures are taken must be omitted.

RESUMO

Background and Objectives: The diagnostic value of thrombophilia remains unknown in young patients with patent foramen ovale (PFO) and stroke. In this study we hypothesized that inherited thrombophilias that lead to venous thrombosis are more prevalent in patients with PFO. Materials and Methods: The study included patients of the tertiary center Vilnius University Hospital Santaros Klinikos who had a cryptogenic ischemic stroke between the ages of 18 and 50 between the years 2008 and 2021. Transient ischemic attacks were excluded. Contrast-enhanced transcranial Doppler ultrasound and extensive laboratory testing were performed. Results: The study included 161 cryptogenic stroke patients (mean age 39.2 ± 7.6 years; 54% female), and a right-to-left shunt was found in 112 (69.6%). The mean time between stroke and thrombophilia testing was 210 days (median 98 days). In total, 61 (39.8%) patients were diagnosed with thrombophilia. The most common finding was hyperhomocysteinemia (26.7%), 14.3% of which were genetically confirmed. Two patients (1.2%) were diagnosed with factor V Leiden mutation, three patients (1.9%) with prothrombin G20210A mutation, one patient (0.6%) had a protein C mutation and one patient (0.6%) had a protein S mutation. No antithrombin mutations were diagnosed in our study population. A total of 45.5% of patients with inherited thrombophilia had a right-to-left shunt, while 54.5% did not, p = 0.092. Personal thrombosis anamnesis was positive significantly more often in patients with antiphospholipid syndrome. Conclusions: The hypothesis of the study was rejected since inherited venous thrombophilia was not significantly more common in patients with PFO. Due to the rarity of thrombophilias in general, more research with a larger sample size is required to further verify our findings.

RESUMO

Background and Objectives: Pregnancy and delivery in patients with congenital heart disease (CHD) and pulmonary arterial hypertension (PAH) carry a very high risk for maternal and foetal complications and are contraindicated according to the guidelines. In the last decades, when an available modern PAH-targeted medication therapy and a new management concept improved patients' well-being and survival, some PAH-CHD females decided to conceive. Of note, despite advanced treatment and modern healthcare system possibilities, dealing with pregnancy in a diverse PAH-CHD population is still challenging. The study aimed to share our experience with PAH-CHD pregnancies and discuss the risk assessment and current management of these patients with the combination of two rare diseases. Materials and Methods: The retrospective search of pulmonary hypertension and adult CHD registries in our hospital was performed, selecting all patients with CHD and PAH who conceived pregnancy from 2013 to 2021. Baseline demographic, clinical, and functional characteristics and clinical outcomes were collected. Results: Thirteen pregnancies in eight patients with PAH-CHD resulted in seven live births, three miscarriages, and three terminations. Five women were diagnosed with Eisenmenger syndrome (ES) and three with residual PAH after CHD repair. Before pregnancy, half of them were in WHO functional class III. Seven (87.5%) patients received targeted PAH treatment with sildenafil during pregnancy. In addition, the two most severe cases were administered with iloprost during peripartum. Three ES patients delivered preterm by Caesarean section under general anaesthesia. No neonatal mortality was reported. Maternal complications were observed in half of our cases. One patient died 12 days after the delivery in another hospital due to deterioration of heart failure. Conclusions: On the basis of our clinical experience, we conclude that pregnancy and delivery carry a high risk for maternal complications and should be avoided in women with PAH-CHD. The individualised approach of multidisciplinary care and appropriate monitoring are mandatory in reducing the risk of adverse outcomes.

RESUMO

Impaired lung function and spirometric signs of airway obstruction without common risk factors for chronic obstructive pulmonary disease could be found in patients with Eisenmenger syndrome. This study aimed to analyse the association between lung function parameters and disease severity (including heart failure markers, associated congenital heart defect) as well as the possible reasons for airflow obstruction in Eisenmenger syndrome. The data of 25 patients with Eisenmenger syndrome were retrospectively evaluated. The patients were divided into groups according to airflow obstruction and a type of congenital heart defect. Airflow obstruction was found in nearly third (32%) of our cases and was associated with older age and worse survival. No relation was found between airway obstruction, B-type natriuretic peptide level, complexity of congenital heart defect and bronchial compression. Most of the patients (88%) had gas diffusion abnormalities. A weak negative correlation was noticed between gas diffusion (diffusing capacity of the lung for carbon monoxide) and B-type natriuretic peptide level (r = -0.437, p = 0.033). Increased residual volume was associated with higher mortality (p = 0.047 and p = 0.021, respectively). A link between B-type natriuretic peptide and lung diffusion, but not airway obstruction, was found. Further research and larger multicentre studies are needed to evaluate the importance of pulmonary function parameters and mechanisms of airflow obstruction in Eisenmenger syndrome.
