The Prognostic Value of Lung Injury and Fibrosis Markers, KL-6, TGF-ß1, FGF-2 in COVID-19 Patients.

Background: Biomarkers of lung injury and interstitial fibrosis give insight about the extent of involvement and prognosis in well-known interstitial lung diseases (ILD). Serum Krebs von den Lungen-6 (KL-6) reflects direct alveolar injury and, transforming growth factor-beta1 (TGF-ß1) and fibroblast growth factor-2 (FGF-2) are principal mediators of fibrosis in ILD and in almost all fibrotic diseases. In this sense, we aimed to assess associations of these biomarkers with traditional inflammatory markers and clinical course of COVID-19. Methods: Patients with COVID-19 who had confirmed diagnosis with SARS-CoV-2 nucleic acid RT-PCR were enrolled and followed up prospectively with a standardized approach one month after diagnosis. Patients were divided into severe and non-severe groups according to National Institutes of Health criteria. Outcome was assessed for the requirement of intensive care unit (ICU) admission, long term respiratory support and death. Blood samples were collected at enrollment and serum levels of KL-6, TGF-ß1, FGF-2 were determined by ELISA. Association between these markers with other prognostic markers and prognosis were analyzed. Results: Overall 31 severe and 28 non-severe COVID-19 patients were enrolled and were compared with healthy control subjects (n = 30). Serum KL-6 levels in COVID-19 patients were significantly higher (median [IQR]; 11.54 [4.86] vs 8.54 [3.98] ng/mL, P = .001] and FGF-2 levels were lower (median [IQR]; 76.84 [98.2] vs 101.62 [210.6] pg/mL) compared to healthy control group. A significant correlation was found between KL-6 values and CRP, fibrinogen, d-dimer and lymphocyte counts. However, we did not find an association between these markers and subsequent severity of COVID-19, mortality and long-term prognosis. Conclusions: Serum KL-6 levels were significantly elevated at the diagnosis of COVID-19 and correlated well with the other traditional prognostic inflammatory markers. Serum levels of principal fibrosis mediators, TGF-ß1, FGF-2, were not elevated at diagnosis of COVID-19, therefore did not help to anticipate long term prognosis.

Anxiety Levels of Primary Caregivers of Children With Tracheostomy During the COVID-19 Pandemic.

We aim to evaluate the anxiety levels of caregivers of children with tracheostomy during the COVID-19 (coronavirus disease 2019) pandemic. Caregivers of 31 children with tracheostomy and 105 healthy children (control group) were included. The State-Trait Anxiety Inventory was administered via teleconference in order to investigate how participants describe how they feel at a particular moment (State) and how they generally feel (Trait). The trait anxiety levels of caregivers of children with tracheostomy were significantly higher (P = .02). Their state anxiety levels were similar. The state and trait anxiety levels of caregivers of children with tracheostomy correlated (r = 0.70, P < .001). At the end of the teleconference, caregivers of children with tracheostomy experienced greater anxiety relief than controls (P < .001). Trait anxiety scores were higher among caregivers of children with tracheostomy, but their state anxiety levels were comparable to those of controls. Caregivers with high trait anxiety also exhibited high state anxiety. Informing caregivers of children with tracheostomy about COVID-19 via teleconference can reduce their anxiety during such stressful times.

Sleep disturbances in children with cystic fibrosis, primary ciliary dyskinesia and typically developing children during COVID-19 pandemic.

AIM: We aimed to investigate sleep disturbances in children with cystic fibrosis (CF) and primary ciliary dyskinesia (PCD) and typically developing (TD) children during the COVID-19 pandemic. METHODS: Primary care givers of children with CF and PCD aged 3-16 years were asked to enrol in the study. Primary care givers of TD children were included as control group. The Sleep Disturbance Scale for Children (SDSC) was used, and questions related to sleep habits during the pandemic were asked. Results of the three groups were compared. RESULTS: Primary care givers of 33 children with CF, 16 children with PCD and 66 TD children were included in the study. There were no differences in terms of age and gender between the three groups. Changes in sleep patterns during the pandemic were more common among TD children and their families, with 75% of the children and 80% of their families sleeping later than before. The sleep initiation and maintenance disorder scores were higher in TD children (P = 0.001), whereas the sleep breathing disorder scores were higher in children with PCD (P = 0.001), and the sleep hyperhidrosis scores were higher in children with CF and PCD (P = 0.011). No relationships were found between sleep parameters and clinical findings of children with lung disease. CONCLUSIONS: Children's sleep habits have changed during the pandemic. Children with chronic lung diseases and even TD children may experience sleep disturbances during this period.

Effect of the COVID-19 pandemic on anxiety among children with cystic fibrosis and their mothers.

BACKGROUND: We aimed to evaluate anxiety among children with cystic fibrosis (CF) and their mothers related to the COVID-19 pandemic. METHODS: A total of 45 patients with CF and their mothers were enrolled in the study together with 90 age-matched healthy children and their mothers as a control group. The State and Trait Anxiety Inventory (STAI) was administered by teleconference with children aged 13 to 18 years old and their mothers. The STAI for children was administered with children aged 9 to 12 years. Results were compared with age-matched healthy children and their mothers. The relationship between anxiety scores of children with CF and their mothers was evaluated by comparing with clinical data of children with CF. At the conclusion of the teleconference, mothers were asked whether their anxiety had changed as a result of the interview. RESULTS: It was found that healthy children aged 13 to 18 years had higher state anxiety scores than age-matched children with CF. Mothers of children with CF had higher trait anxiety scores, especially those of children aged 0 to 12 years, than mothers of healthy children (P < .05). For mothers of children with CF, state anxiety scores were higher among those whose children had chronic Pseudomonas infection (P < .05). Most mothers of children with CF stated that their anxiety decreased following the interview. CONCLUSION: The COVID-19 pandemic may increase anxiety among mothers of children with CF as well those with healthy children. However, COVID-19 had no effect on the anxiety of children with CF. Informing parents of children with CF about COVID-19 by teleconference may decrease anxiety.
