Stress and coping strategies of families of pediatric solid organ transplant recipients in times of pandemic.

Objective: Pediatric solid organ transplantation (SOT) is a chronic condition that impacts the whole family system. The objective of this study is to evaluate psychopathology, family stress, and coping strategies in families of SOT recipients compared to families of healthy children and adolescents. Moreover, it analyzes if the stress related to the COVID-19 pandemic has had an additional impact on these families. Methods: The sample was recruited between May and July 2021, during the fourth and fifth wave of the pandemic in Spain. It consisted of 102 families, 51 with a pediatric recipient who had undergone a SOT (liver, kidney, heart, or lung) and 51 healthy controls, matched by child age and gender. A primary caregiver from each family answered an online sociodemographic questionnaire and different tests to evaluate family stress, depression, anxiety, coping strategies, and effects of the pandemic on the family. Results: Caregivers were mostly mothers (89.2%). Families of SOT recipients showed greater anxiety (U = 863.5, p = 0.003) and more total stress, stress related to childcare (t = -2.043; p = 0.045), and parent-child interaction stress (U = 355.5, p = 0.015). SOT families used more avoidance strategies, specifically denial (U = 889.5; p = 0.010) and abandonment of coping efforts (U = 1,013; p = 0.047), more religious strategies (U = 792.5; p = 0.031), and fewer social support coping strategies (t = 2.098; p = 0.038). No differences were found between groups in terms of exposure, impact, and distress more than 1 year after the start of the pandemic. Conclusion: SOT families showed clinical levels of anxiety, more parent-child interaction stress, more difficulties in taking care of their child, more avoidance and religious strategies, and less use of social support strategies, even 4 years after transplantation. The pandemic did not have an additional differential effect on SOT families. Caregivers of SOT patients can benefit from psychological interventions focused on parents' mental health, parent-child connectedness, skill building, and social support aid groups, with attention to multiculturalism and promoting a better balance between caregivers. There is a need for family interventions that are maintained over time. Strategies that offer this support to families through digital resources can facilitate adjustment to chronic illness, especially in pandemic times.

Differences between genetic dilated cardiomyopathy and myocarditis in children presenting with severe cardiac dysfunction.

Acute myocarditis is an inflammatory disease of the myocardium, and it can present as severe heart failure in children. Differential diagnosis with genetic cardiomyopathy can be difficult. The objective of this study is to identify patterns of clinical presentation and to assess invasive and non-invasive measures to differentiate patients with acute myocarditis from patients with dilated genetic cardiomyopathy. We performed a retrospective descriptive study of all paediatric patients (0-16 years old) that presented with new-onset heart failure with left ventricle ejection fraction < 35% in whom we performed an endomyocardial biopsy (EMB) during the period from April 2007 to December 2020. The patients were classified into two groups: Group 1 included 18 patients with myocarditis. Group 2 included 9 patients with genetic cardiomyopathy. Findings favouring a diagnosis of myocarditis included a fulminant or acute presentation (77.8% vs 33.3%, p = 0.01), higher degree of cardiac enzyme elevation (p = 0.011), lower left ventricular dimension z-score (2.2 vs 5.4, p = 0.03) increase of ventricular wall thickness (88.8% vs 33.3%, p = 0.03) and oedema in the EMB. Seven (77.8%) patients with genetic cardiomyopathy had inflammation in the endomyocardial biopsy fulfilling the diagnostic criteria of inflammatory cardiomyopathy.Conclusion: Differentiating patients with a myocarditis from those with genetic cardiomyopathy can be challenging, even performing an EMB. Some patients with genetic cardiomyopathy fulfil the diagnostic criteria of inflammatory cardiomyopathy. Using invasive and non-invasive measures may be useful to develop a predictive model to differentiate myocarditis from genetic cardiomyopathy. What is Known: • Acute myocarditis could present with cardiogenic shock in paediatric patients. • Parvovirus B19 is the main cause of myocarditis in this population. What is New: • Current diagnostic criteria for myocarditis have limited use in paediatric patients presenting with new-onset heart failure. • Some patients with a genetic cardiomyopathy and a new-onset heart failure fulfill the diagnostic criteria of inflammatory cardiomyopathy.

QTc interval prolongation in patients infected with SARS-CoV-2 and treated with antiviral drugs☆☆☆ Evolución del intervalo QTc en pacientes con infección SARS-COV-2 tratados con farmacos antivirales

Introduction Many antiviral agents, such as hydroxychloroquine, have been used to treat COVID-19, without being broadly accepted. QTc prolongation is a worrisome adverse effect, scarcely studied in pediatrics. Patients and methods Paediatric patients affected from COVID-19 who received antivirals were matched (1:2) with controls not infected nor exposed. Electrocardiograms were prospectively analyzed at baseline, during the first 72 h of treatment and after 72 h. Results Eleven (22.9%) out of 48 patients admitted due to COVID-19 (March–July 2020) received antiviral therapy. All had underlying diseases: congenital heart disease (4/11;36.4%) and immunosuppression (3/11;27.3%) stand out. 5/11 (45.5%) received treatment at baseline with a potential effect on QTc. There where no differences observed in the baseline QTc between cases and controls: 414.8 ms (49.2) vs 416.5 ms (29.4), (P = .716). Baseline long QT was observed in 2/11 cases and 2/22. Among cases, 10/11 (90.9%) received hydroxychloroquine, mainly associated with azithromycin (8/11;72.7%), 3 received lopinavir/ritonavir and one remdesivir. The median increase in QTc after 72 h under treatment was 28.9 ms [IQR 48.7] (P = .062). 4/11 (36.4%) patients had a long QTc at 72 h, resulting in 3 patients ≥500 ms;treatment was stopped in one (QTc 510 ms) but ventricular arrhythmias were not documented. Conclusions The use of antivirals caused an increase on the QTc interval after 72 h of treatment, being the QTc long in 36.3% of the patients, although no arrhythmic events were observed. The use of hydroxychloroquine and antivirals requires active QTc monitoring and it is recommended to discontinue treatment if QTc > 500 ms.

Impact of COVID-19 on Families of Pediatric Solid Organ Transplant Recipients.

OBJECTIVE: The COVID-19 pandemic and lockdown measures have had a clear psychological impact on families, and specifically those with children with chronic illnesses have reported greater overloads and exhaustion. The objective of this study was to evaluate the exposure, impact and experience of the pandemic on families of pediatric solid organ transplant (SOT) recipients compared to families of healthy children and adolescents. METHODS: We recruited 96 families, 48 with a pediatric SOT recipient and 48 healthy controls, matched by child age and gender. A primary caregiver from each family responded to an online sociodemographic questionnaire and the COVID-19 Exposure and Family Impact Survey (CEFIS), which explores the exposure, impact and experience of the pandemic and lockdown on families. RESULTS: Exposure to the pandemic was greater in families of healthy children and adolescents. The impact was mostly negative in both groups: caregivers reported increased anxiety (76%) and mood disturbances (71.9%) and hindered quality of sleep (64.6%) and health habits (58.3%). On the positive side, family relationships improved. Qualitatively, the SOT group positively perceived isolation and established hygienic measures as protective and destigmatizing, although they reported fear of virus transmission to their child. CONCLUSIONS: The psychological impact of the pandemic has been similar in both groups, although families of transplant recipients have protected themselves more, probably because they are used to prevention measures and they see contagion as a graver risk. Additionally, SOT recipients' families presented some idiosyncratic elements, especially a decrease in their perception of stigma associated with the medical condition.
