Post-Ebola sequelae among Ebola child survivors in Sierra Leone

Assessment of prevalence and determinants of anxiety and psychological distress symptoms in Ebola child and adolescent survivors and orphans in Eastern Democratic Republic of the Congo during the COVID-19 pandemic

BACKGROUND

To date, only three studies investigated the mental health of youth affected by Ebola virus disease (EVD). None explored anxiety and psychological distress symptoms in survivors or orphans. This study aimed to investigate the prevalence and determinants of anxiety and psychological distress symptoms among survivors and orphans of the 2018-2020 Ebola epidemic in Eastern Democratic Republic of the Congo (DRC) during the COVID-19 pandemic.

METHODS

A representative sample of 416 participants (mean age = 13.37, SD = 2.79, 51.20 % girls, 146 survivors, 233 orphans, and 34 orphan-survivor participants) completed measures evaluating anxiety, psychological distress, exposure, resilience, stigmatization related to Ebola and COVID-19.

RESULTS

55.88 % and 55.96 % of survivors and orphans experienced severe symptoms of anxiety and psychological distress. Participants who were both survivors and orphans presented higher prevalence of anxiety and psychological distress (94.12 % and 100 %) compared to survivors (74.03 % and 81.82 %) or orphans (37.99 % and 33.33 %), χ2 = 70.63, p < .001; χ2 = 113.50, p < .001. Ebola and COVID-19 related stigmatization were the most important determinants of anxiety (B = 0.40, p < .001; B = 0.37, p < .001) and psychological distress (B = 0.48, p < .001; B = 0.44, p < .001). Resilience was negatively associated with both anxiety and psychological distress. The final regression models explained 49 % and 85 % of the variance of anxiety and psychological distress.

LIMITATIONS

The cross-sectional design used prevents to establish causal link.

CONCLUSIONS

Ebola children and adolescents' survivors and orphans are at major risk of experiencing anxiety and psychological distress in Eastern RDC affected by years of armed conflict. Massive resources are needed to develop and implement programs to reduce stigma and support mental health.

Prevalence of somatic symptoms among Ebola Virus Disease (EVD) survivors in Africa: a systematic review and meta-analysis

BACKGROUND

Many Ebola virus disease (EVD) survivors have reported somatic and neuropsychological symptoms after discharge from the Ebola Treatment Unit (ETU). Since the 2014-2016 Ebola epidemic in West Africa, various studies have investigated and identified these symptoms. Evidence on somatic symptoms is widely available in the literature, however, there is no concise overview of the prevalence across different time intervals.

METHODS

This meta-analysis was conducted following the (PRISMA) guidelines. A database search was conducted to identify original studies that reported the prevalence of symptoms. The primary outcome measure was the prevalence rate of several somatic symptoms. Results were pooled, and prevalence rates were assessed over time, to elucidate any particular trends.

RESULTS

We included 23 studies (5,714 participants). The pooled prevalence was: arthralgia 50% (95% CI: 41%-59%); headache 44% (95% CI: 36%-52%); myalgia 32% (95% CI: 26%-38%); abdominal pain 27% (95% CI: 15%-39%); fatigue 25% (95% CI: 19%-31%); numbness of feet 16% (95% CI: 14%-18%); numbness of hands 12% (95% CI: 10%-14%) and hearing loss 9% (95% CI: 5%-12%). Prevalence across different time intervals revealed significant patterns. All the symptoms persisted for more than 2 years after discharge except for abdominal pain.

CONCLUSION

The pooled prevalence rates of somatic symptoms are notably high. Arthralgia and headache are the most prevalent of the symptoms, with hearing loss and numbness in hands and feet being the least. We found that arthralgia, myalgia, and abdominal pain decreased over time. However, headache, fatigue, numbness of hands and feet, and hearing loss increased over time.

Ebola virus disease in children: epidemiology, pathogenesis, management, and prevention

Ebola disease is a severe disease with extremely high case-fatality rates ranging from 28-100%. Observations made during the 2013-2016 West African epidemic improved our understanding of the clinical course of Ebola disease and accelerated the study of therapeutic and preventative strategies. The epidemic also highlighted the unique challenges associated with providing optimal care for children during Ebola disease outbreaks. In this review, we outline current understanding of Ebola disease epidemiology, pathogenesis, management, and prevention, highlighting data pertinent to the care of children. IMPACT: In this review, we summarize recent advancements in our understanding of Ebola disease epidemiology, clinical presentation, and therapeutic and preventative strategies. We highlight recent data pertinent to the care of children and pregnant women and identify research gaps for this important emerging viral infection in children.

Prevalence and Factors Related to Post-traumatic Stress Disorder and Depression Symptoms Among Children and Adolescents Survivors and Orphans of Ebola Virus Disease in Democratic Republic of the Congo Eastern Regions During the COVID-19 Pandemic

PURPOSE

Although previous studies have shown a high prevalence of mental health problems among adult Ebola virus disease survivors, no studies have yet been conducted on mental health problems among children and adolescents in affected regions. Consequently, the current study aimed to examine the prevalence and factors associated with depression and post-traumatic stress disorder (PTSD) among children and adolescent survivors and orphans by utilizing a cross-sectional survey following the 2018-2020 epidemic in Eastern Democratic Republic of the Congo.

METHODS

A total of 146 survivors (mean age = 13.62, standard deviation [SD] = 2.50, 49.32% female), 233 orphans (mean age = 13.18, SD = 2.96, 53.32% female), and 34 orphan-survivor participants (mean age = 13.39, SD = 2.87, 44.12% female) were recruited. Participants completed measures assessing depression and PTSD symptoms, traumatic experiences, and stigma related to Ebola and COVID-19.

RESULTS

The prevalence of depression and PTSD symptoms was 87.32% and 44.42%, respectively. Results showed significant differences in depression and PTSD symptoms between orphan-survivors (100% and 97.06%), survivors (90.21% and 75.86%), and orphans (83.48% and 16.52%; χ2(2) = 9.02; p = .011 and χ2(2) = 168.85; p < .001). Experience of traumatic events, Ebola stigmatization, and COVID-19 stigmatization positively predicted depression and PTSD symptoms. The regression models explained 61%-72% of the variance of depression and PTSD.

DISCUSSION

The results reveal that the Ebola virus disease and its associated grief severely jeopardize the mental health of children and adolescents in affected regions. Despite the relative paucity of resources, intervention programs may be helpful to minimize associated stigma and promote psychological support.

Prevalence and determinants of anxiety, depression and comorbid anxiety-depression symptoms among adolescents in Ebola-affected zones

BACKGROUND

Ebola virus disease (EVD) has been shown to be associated with poor mental health in affected zones. However, no study has yet explored its impact on adolescents' mental health.

AIMS

This study aimed to assess the prevalence and risk factors associated with depression and anxiety symptoms among adolescents in EVD-affected areas in the Equateur Province of the Democratic Republic of the Congo during the COVID-19 pandemic.

METHOD

A provincial sample of adolescents aged 12-17 years (M = 14.84, s.d. = 1.49) living in the 18 urban and rural areas affected by the 2018 EVD outbreak completed a two-wave longitudinal survey. Surveys assessed symptoms of depression and anxiety, exposure to Ebola, social support and sociodemographic information.

RESULTS

A total of 490 participants completed the baseline and follow-up surveys, 50% of whom were female. Elevated and worsened depressive symptoms were observed among participants from the baseline (56.94%) to the follow-up (91.43%; z = -11.37, P < 0.001), whereas anxiety symptoms decreased from the baseline (36.33%) to follow-up (24.90%; z = 4.06, P < 0.001). The final generalised estimating equation model showed that anxiety symptoms decreased over time (B = -3.92, P < 0.001), while depression symptoms increased (B = 4.79, P < 0.001). Stigmatisation related to Ebola positively predicted anxiety (B = 5.41, P < 0.001) and depression symptoms (B = 0.4452, P = 0.009). Social support negatively predicted anxiety (B = -1.13, P = 0.004) and depression (B = -0.98, P < 0.001) symptoms but only moderated the association between stigmatisation and depression symptoms (B = -0.67, P < 0.001).

CONCLUSIONS

Most adolescents living in EVD-affected areas experience mental health issues. Stigmatisation related to EVD and living in urban areas are the most consistent predictors of mental health problems. Nevertheless, social support remains a protective factor for depression and anxiety symptoms and a necessary resource for building resilience.

The prevalence of Post-Ebola Syndrome hearing loss, Sierra Leone

BACKGROUND

Globally, hearing loss is the second leading cause of disability, affecting approximately 18.7% of the world's population. However, the burden of hearing loss is unequally distributed, with the majority of affected individuals located in Asia or Sub-Saharan Africa. Following the 2014 West African Ebola Outbreak, disease survivors began to describe hearing loss as part of the constellation of symptoms known as Post-Ebola Syndrome. The goal of this study was to more fully characterize hearing loss among Ebola Virus Disease (EVD) survivors.

METHODOLOGY AND PRINCIPAL FINDINGS

EVD survivors and their household contacts were recruited (n = 1,12) from Eastern Sierra Leone. Each individual completed a symptom questionnaire, physical exam, and a two-step audiometry process measuring both air and bone conduction thresholds. In comparison to contacts, EVD survivors were more likely to have complaints or abnormal findings affecting every organ system. A significantly greater percentage of EVD survivors were found to have hearing loss in comparison to contacts (23% vs. 9%, p < 0.001). Additionally, survivors were more likely to have bilateral hearing loss of a mixed etiology. Logistic regression revealed that the presence of any symptoms of middle or inner ear (p < 0.001), eye (p = 0.005), psychiatric (p = 0.019), and nervous system (p = 0.037) increased the odds of developing hearing loss.

CONCLUSIONS AND SIGNIFICANCE

This study is the first to use an objective and standardized measurement to report hearing loss among EVD survivors in a clinically meaningful manner. In this study it was found that greater than 1/5th of EVD survivors develop hearing loss. The association between hearing impairment and symptoms affecting the eye and nervous system may indicate a similar mechanism of pathogenesis, which should be investigated further. Due to the quality of life and socioeconomic detriments associated with untreated hearing loss, a greater emphasis must be placed on understanding and mitigating hearing loss following survival to aid in economic recovery following infectious disease epidemics.
