ABSTRACT
Purpose: To investigate the quality of life (QoL) of survivors from severe forms of COVID-19 treated in the ICU. Methods: In this study, we investigated the QoL of patients with severe COVID-19 treated in the ICU from November 2021 to February 2022. In the study period, 288 patients were treated in ICU and 162 were alive at the time of analysis. Of those, 113 patients were included in this study. QoL was analyzed 4 months after ICU admission using the EQ-5D-5L questionnaire administered by telephone. Results: Of the 162 surviving patients, 46% reported moderate to severe problems in the anxiety/depression domain, 37% had moderate to severe problems in usual activities, and 29% in the mobility domain. Older patients had lower QoL in mobility, self-care and usual activities domains. Female patients had lower QoL in usual activities, while male patients had lower QoL in the self-care domain. Patients who spent longer time on invasive respiratory support and those with longer hospital lengths of stay had lower QoL in all domains. Conclusion: Severe COVID-19 reduces HRQoL in a significant number of survivors 4 months after ICU admission. Early recognition of patients at increased risk for reduced QoL could lead to early focused rehabilitation and improved QoL of these patients.
ABSTRACT
Accumulating data suggest that various neurologic manifestations are reported in critically-ill COVID-19 patients. Although low testosterone levels were associated with poor outcomes, the relationship between testosterone levels and indices of brain injury are still poorly understood. Therefore, we aimed to explore whether testosterone levels are associated with glial fibrillary acidic protein (GFAP) and ubiquitin carboxy-terminal hydrolase L1 (UCH-L1), biomarkers of brain injury, in patients with a severe form of COVID-19. The present study was conducted on 65 male patients aged 18-65 with severe COVID-19. Blood samples were collected at three time points: upon admission to ICU, 7 days after, and 14 days after. In patients with neurological sequels (n = 20), UCH-L1 serum concentrations at admission were markedly higher than in patients without them (240.0 (155.4-366.4) vs. 146.4 (92.5-243.9) pg/mL, p = 0.022). GFAP concentrations on admission did not differ between the groups (32.2 (24.2-40.1) vs. 29.8 (21.8-39.4) pg/mL, p = 0.372). Unlike GFAP, UCH-L1 serum concentrations exhibited a negative correlation with serum testosterone in all three time points (r = -0.452, p < 0.001; r = -0.430, p < 0.001 and r = -0.476, p = 0.001, respectively). The present study suggests that the traumatic brain injury biomarker UCH-L1 may be associated with neurological impairments seen in severe COVID-19. Moreover, a negative correlation between UCH-L1 and serum testosterone concentrations implies that testosterone may have a role in the development of neurological sequels in critically-ill COVID-19 patients.
ABSTRACT
The effect of routine inhalation therapy on ventilator-associated pneumonia (VAP) in mechanically ventilated patients with the coronavirus disease (COVID-19) has not been well-defined. This randomized controlled trial included 175 eligible adult patients with COVID-19 who were treated with mechanical ventilation at the University Hospital of Split between October 2020 and June 2021. Patients were randomized and allocated to a control group (no routine inhalation) or one of the treatment arms (inhalation of N-acetylcysteine; 5% saline solution; or 8.4% sodium bicarbonate). The primary outcome was the incidence of VAP, while secondary outcomes included all-cause mortality. Routine inhalation therapy had no effect on the incidence of bacterial or fungal VAP nor on all-cause mortality (p > 0.05). Secondary analyses revealed a significant reduction of Gram-positive and methicillin-resistant Staphylococcus aureus (MRSA) VAP in the treatment groups. Specifically, the bicarbonate group had a statistically significantly lower incidence of Gram-positive bacterial VAP (4.8%), followed by the N-acetylcysteine group (10.3%), 5% saline group (19.0%), and control group (34.6%; p = 0.001). This difference was driven by a lower incidence of MRSA VAP in the bicarbonate group (2.4%), followed by the N-acetylcysteine group (7.7%), 5% saline group (14.3%), and control group (34.6%; p < 0.001). Longer duration of ventilator therapy was the only significant, independent predictor of any bacterial or fungal VAP in the multivariate analysis (aOR 1.14, 95% CI 1.01-1.29, p = 0.038 and aOR 1.05, 95% CI 1.01-1.10, p = 0.028, respectively). In conclusion, inhalation therapy had no effect on the overall VAP incidence or all-cause mortality. Further studies should explore the secondary findings of this study such as the reduction of Gram-positive or MRSA-caused VAP in treated patients.
