Objective: To estimate for the first time the burden of fungal infections in Romania. Methods: Data derived from the World Health Organization (WHO), National Institute of Statistics, Romanian public health agencies and non-profit health organizations, and published annual reports on local epidemiology were used in the present study. When no data were available, specific at-risk populations were used to calculate frequencies of serious fungal diseases, using previously published epidemiological parameters. All data refer to the year 2016. Results: The estimated number of serious fungal infections in Romanian population was 436,230 in 2016. Recurrent vulvovaginal candidiasis accounted for up to 80% of total cases (more than 350,000 women annually). Concerning HIV-related infections, among 14,349 infected persons, Pneumocystis pneumonia occurred in about 10% of late presenters (30 cases in 2016), while cryptococcal meningitis was rarely diagnosed (less than 20 cases). Annually, the total number of oesophageal candidiasis and oral thrush cases in HIV-positive patients may have been as high as 1229 and 3066, respectively. In immunocompromised and cancer patient populations, the annual incidence of candidaemia was 295, and at least 458 invasive aspergillosis cases and 4 mucormycosis cases occurred yearly. With 4966 critical care beds and approximately 200,000 abdominal surgeries performed, the estimated annual incidence of candidaemia and Candida peritonitis was 689 and 344, respectively. The annual incidence of pulmonary tuberculosis is still high in Romania (12,747 cases). Thus, the prevalence of post-TB chronic pulmonary aspergillosis is estimated to be 8.98/100,000 (1768 cases). The prevalence of chronic obstructive pulmonary disease (COPD) and asthma in adults is 6% and 6.5%, respectively. Therefore, allergic bronchopulmonary aspergillosis prevalence is estimated at 29,387 and severe asthma with fungal sensitisation at 38,731 cases annually. Conclusions: Not being on the list of reportable diseases, the number of patients presenting with severe mycoses in Romania can only be roughly estimated. Based on local reports and prevalence estimation, we consider that at least 2.23% of Romanians suffer from a serious form of fungal disease.

COVID-19, the infectious disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), is frequently associated with pulmonary thrombotic events, especially in hospitalized patients. Severe SARS-CoV-2 infection is characterized by a proinflammatory state and an associated disbalance in hemostasis. Immune pathology analysis supports the inflammatory nature of pulmonary arterial thrombi composed of white blood cells, especially neutrophils, CD₃⁺ and CD₂₀⁺ lymphocytes, fibrin, red blood cells, and platelets. Immune cells, cytokines, chemokines, and the complement system are key drivers of immunothrombosis, as they induce the damage of endothelial cells and initiate proinflammatory and procoagulant positive feedback loops. Neutrophil extracellular traps induced by COVID-19-associated “cytokine storm”, platelets, red blood cells, and coagulation pathways close the inflammation–endotheliopathy–thrombosis axis, contributing to SARS-CoV-2-associated pulmonary thrombotic events. The hypothesis of immunothrombosis is also supported by the minor role of venous thromboembolism with chest CT imaging data showing peripheral blood clots associated with inflammatory lesions and the high incidence of thrombotic events despite routine thromboprophylaxis. Understanding the complex mechanisms behind COVID-19-induced pulmonary thrombosis will lead to future combination therapies for hospitalized patients with severe disease that would target the crossroads of inflammatory and coagulation pathways.

ObjectivesTo investigate the vitamin D status during winter of a healthy population of hospital employees and to assess the correlation between vitamin D status and risk of infections in the upper respiratory tract.DesignOne hundred and ten healthy volunteers answered a questionnaire on their solar exposure habits and vitamin D intake and delivered one blood sample for quantification of vitamin D level (serum 25-hydroxyvitamin D (25(OH)D) concentration) during December 2007–January 2008. At the end of the winter we screened for the occurrence of respiratory infections and sought associations with vitamin D status.SettingBucharest, Romania, 45°N.SubjectsOne hundred and ten healthy hospital employees.ResultsEighty per cent of participants were vitamin D deficient (25(OH)D level below 50 nmol/l). The main determinant of serum 25(OH)D was sun exposure during the summer previous to the study (P = 0·02 in multivariate analysis). Intake of vitamin D, BMI and age played no significant role for the level of 25(OH)D. Overall we found a non-significant negative correlation between 25(OH)D level and new cases of infection (Spearman correlation coefficient of −0·12, P = 0·2).ConclusionsVitamin D status is alarmingly poor in active, relatively young women residing in Romania. If our results are reproduced by other investigations, action to improve vitamin D status at the population level is necessary. We were not able to show a statistically significant relationship between vitamin D status and infection risk in our material.

The COVID-19 virus frequently causes neurological complications. These have been described in various forms in adults and children. Headache, seizures, coma, and encephalitis are some of the manifestations of SARS-CoV-2-induced neurological impairment. Recent publications have revealed important aspects of viral pathophysiology and its involvement in nervous-system impairment in humans. We evaluated the latest literature describing the relationship between COVID-19 infection and the central nervous system. We searched three databases for observational and interventional studies in adults published between December 2019 and September 2022. We discussed in narrative form the neurological impairment associated with COVID-19, including clinical signs and symptoms, imaging abnormalities, and the pathophysiology of SARS-CoV2-induced neurological damage.
