Epidemiological and Clinical Characteristics of COVID-19 in Indian Children in the Initial Phase of the Pandemic

Neurological complications and effects of COVID-19: Symptoms and conceivable mechanisms

A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first identified in December 2019 in Wuhan, China. The new coronavirus disease (COVID-19) was declared a global pandemic by the World Health Organization (WHO) in March 2020. SARS-CoV-2 can invade the nervous system aside from infecting the respiratory system as its primary target. The most common nervous system symptoms of COVID-19 are stated as headache, myalgia, fatigue, nausea, vomiting, sudden and unexplained anosmia, and ageusia. More severe conditions such as encephalomyelitis, acute myelitis, thromboembolic events, ischemic stroke, intracerebral hemorrhage, Guillain-Barré-syndrome, Bell's palsy, rhabdomyolysis, and even coma have also been reported. Cohort studies revealed that neurological findings are associated with higher morbidity and mortality. The neurological symptoms and manifestations caused by SARS-CoV-2 and COVID-19 are examined and summarized in this article.

A systematic review and meta-analysis of otorhinolaryngological manifestations of coronavirus disease 2019 in paediatric patients

BACKGROUND

This meta-analysis provides a quantitative measure of the otorhinolaryngological manifestations of coronavirus disease 2019 in children.

METHODS

A structured literature review was carried out using PubMed, Embase and Cochrane Central, employing pertinent search terms. The statistical analysis was performed using Stata version 14.2 software, and the analysed data were expressed as the pooled prevalence of the symptoms with 95 per cent confidence intervals.

RESULTS

The commonest symptoms noted were cough (38 per cent (95 per cent confidence interval = 33-42; I² = 97.5 per cent)), sore throat (12 per cent (95 per cent confidence interval =10-14; I² = 93.7 per cent)), and nasal discharge (15 per cent (95 per cent confidence interval = 12-19; I² = 96.9 per cent)). Anosmia and taste disturbances showed a pooled prevalence of 8 per cent each. Hearing loss, vertigo and hoarseness were rarely reported.

CONCLUSION

Cough, sore throat and nasal discharge were the commonest otorhinolaryngological symptoms in paediatric patients with coronavirus disease 2019. Compared with adults, anosmia and taste disturbances were infrequently reported in children.

Predictors of mortality in children admitted with SARS-CoV-2 infection to a tertiary care hospital in North India

AIM

To compare the demographic, clinical, laboratory and radiological parameters of patients with different clinical outcomes (death or discharge) and analyse them to find out the potential predictors for mortality in children hospitalised with SARS-CoV-2 infection.

METHODS

Retrospective chart review of all patients less than 18 years of age with laboratory-confirmed SARS-CoV-2 infection and requiring hospital admission between 16 April 2020 and 31 October 2020.

RESULTS

Of 255 children with SARS-CoV-2 infection, 100 patients (median age 62.5 months, 59% males, 70% with moderate to severe disease) were hospitalised, of whom 27 died (median age 72 months, 59% males and 30% severely underweight). The subgroup with comorbidities (n = 14) was older (median age 126 months) and had longer duration of stay (median 10 days). Fever and respiratory symptoms were comparable while gastrointestinal symptoms were more common among non-survivors. Hypoxia at admission (odds ratio (OR) 5.48, P = 0.001), multiorgan dysfunction (OR 75.42, P = 0.001), presence of acute kidney injury (OR 11.66, P = 0.001), thrombocytopenia (OR 4.40, P = 0.003) and raised serum C-reactive protein (CRP) (OR 4.69, P = 0.02) were independently associated with mortality. The median time from hospitalisation to death was 3 days. The deceased group had significantly higher median levels of inflammatory parameters and a higher incidence of complications (myocarditis, encephalitis, acute respiratory distress syndrome and shock).

CONCLUSIONS

Hypoxia at admission, involvement of three or more organ systems, presence of acute kidney injury, thrombocytopenia and raised serum C-reactive protein were found to be independently associated with increased odds of in-hospital mortality in children admitted with SARS-CoV-2 infection.

Clinical profile of coronavirus disease 2019 comparing the first and second waves: A single-center study from North India

Background and Objectives:

Severe acute respiratory syndrome coronavirus 2, caused by the novel coronavirus disease 2019 (COVID-19), led to a devastating pandemic that hit majority of the countries globally in a wave-like pattern. The characteristics of the disease varied in different geographical areas and different populations. This study highlights the epidemiological and clinical characteristics of COVID-19 during two major waves in North India.

Materials and Methods:

Clinical characteristics and outcomes of all COVID-19-reverse transcription-polymerase chain reaction-positive patients, admitted from March 2020 to June 2021, to a tertiary care center in North India, were studied retrospectively.

Results:

During this period, total of 5652 patients were diagnosed having COVID. Patients who were incidentally diagnosed as COVID-positive (n=667) with other unrelated comorbid conditions and patients admitted under level 1 facility (n=1655; 1219 from first and 436 from second wave) were excluded from final analysis. Males were most commonly affected in both waves, with male to female ratio 4:1 in first and 3:1 in second wave. First wave had significantly more people with co-morbidities like diabetes mellitus and hypertension (P=0.001), whereas younger age group (age <40 years) were significantly more affected in second wave (P= 0.000). Fever was the most common presenting complaint in both waves, followed by cough and breathlessness. Patients during first wave had more severe disease at presentation and high mortality compared to the second wave.

Conclusion:

Majority of the patients with COVID-19 infection presenting to our hospital were young during the second wave. Fever was noted as presenting manifestation. Mortality was low during the second wave as compared to the first wave, likely to be due to proper protocol-based treatment resulting in better outcomes.

L, Kariyappa M, Devadas S, Kumble D, Sajjan SV, Rangegowda RK, Patel AS. Acute Ischemic Stroke in a Young Child and Its Association with SARS-CoV-2 Infection

The coronavirus disease 2019 (COVID-19) in children has been shown to have lower morbidity and mortality in children as compared with adults. The neurological complications related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are increasingly reported in children, yet the cerebrovascular complications are rare. We report a case of a toddler who presented with right-sided hemiparesis and motor aphasia, with an antecedent history suggestive of COVID-19 infection. The child tested negative on the nasopharyngeal swab for real-time reverse transcription-polymerase chain reaction (RT-PCR), but the serology for anti-SARS-CoV-2 IgG assay was positive. The neuroimaging showed an acute infarct in the left middle cerebral artery territory. A detailed evaluation for causes of childhood stroke was unrevealing, except for the presence of severe iron deficiency anemia (IDA). The child was diagnosed as acute ischemic stroke (AIS) most probably secondary to mild COVID-19 infection. The objective of this case report is to explain the possibility of AIS after a mild COVID-19 infection, complicated by the underlying severe IDA. Therefore, an association between COVID-19 and stroke in children needs to be emphasized and RT-PCR for SARS-CoV-2 as well as serological assay must be included in the workup of stroke in the young.

Neurological Manifestations in COVID-19 Patients: A Meta-Analysis

Common symptoms such as dizziness, headache, olfactory dysfunction, nausea, vomiting, etc. in COVID-19 patients have indicated the involvement of the nervous system. However, the exact association of the nervous system with COVID-19 infection is still unclear. Thus, we have conducted a meta-analysis of clinical studies associated with neurological problems in COVID-19 patients. We have searched for electronic databases with MeSH terms, and the studies for analysis were selected based on inclusion and exclusion criteria and quality assessment. The Stats Direct (version 3) was used for the analysis. The pooled prevalence with 95% confidence interval of various neurological manifestations reported in the COVID-19 patients was found to be headache 14.6% (12.2-17.2), fatigue 33.6% (29.5-37.8), olfactory dysfunction 26.4% (21.8-31.3), gustatory dysfunction 27.2% (22.3-32.3), vomiting 6.7% (5.5-8.0), nausea 9.8% (8.1-11.7), dizziness 6.7% (4.7-9.1), myalgia 21.4% (18.8-24.1), seizure 4.05% (2.5-5.8), cerebrovascular diseases 9.9% (6.8-13.4), sleep disorders 14.9% (1.9-36.8), altered mental status 17.1% (12.3-22.5), neuralgia 2.4% (0.8-4.7), arthralgia 19.9% (15.3-25.0), encephalopathy 23.5% (14.3-34.1), encephalitis 0.6% (0.2-1.3), malaise 38.3% (24.7-52.9), confusion 14.2% (6.9-23.5), movement disorders 5.2% (1.7-10.4), and Guillain-Barre syndrome 6.9% (2.3-13.7). However, the heterogeneity among studies was found to be high. Various neurological manifestations related to the central nervous system (CNS) and peripheral nervous system (PNS) are associated with COVID-19 patients.

Clinical Profile and Risk Factors for Severe Disease in 402 Children Hospitalized with SARS-CoV-2 from India: Collaborative Indian Pediatric COVID Study Group

INTRODUCTION

There is a lack of large multicentric studies in children with COVID-19 from developing countries. We aimed to describe the clinical profile and risk factors for severe disease in children hospitalized with COVID-19 from India.

METHODS

In this multicentric retrospective study, we retrieved data related to demographic details, clinical features, including the severity of disease, laboratory investigations and outcome.

RESULTS

We included 402 children with a median (IQR) age of 7 (2-11) years. Fever was the most common symptom, present in 38.2% of children. About 44% had underlying comorbidity. The majority were asymptomatic (144, 35.8%) or mildly symptomatic (219, 54.5%). There were 39 (9.7%) moderate-severe cases and 13 (3.2%) deaths. The laboratory abnormalities included lymphopenia 25.4%, thrombocytopenia 22.1%, transaminitis 26.4%, low total serum protein 34.7%, low serum albumin 37.9% and low alkaline phosphatase 40%. Out of those who were tested, raised inflammatory markers were ferritin 58.9% (56/95), c-reactive protein 33.3% (41/123), procalcitonin 53.5% (46/86) and interleukin-6 (IL-6) 76%. The presence of fever, rash, vomiting, underlying comorbidity, increased total leucocyte count, thrombocytopenia, high urea, low total serum protein and raised c-reactive protein was factors associated with moderate to severe disease.

CONCLUSION

Fever was the commonest symptom. We identified additional laboratory abnormalities, namely lymphopenia, low total serum protein and albumin and low alkaline phosphatase. The majority of the children were asymptomatic or mildly symptomatic. We found high urea and low total serum protein as risk factors for moderate to severe disease for the first time.

Gastrointestinal Manifestations of Pediatric Coronavirus Disease and Their Relationship with a Severe Clinical Course: A Systematic Review and Meta-analysis

BACKGROUND

Data on the gastrointestinal (GI) manifestations of Pediatric Corona Virus Disease (COVID-19) are conflicting and the relationship between GI involvement and the severity of COVID-19 disease has not been evaluated. The objectives of this systematic review were to determine the GI manifestations of pediatric COVID-19 and to evaluate their role as risk factors for a severe clinical course.

METHODS

: A systematic literature search was carried out in PubMed and Scopus for studies published before 31 December 2020 with information about the GI manifestations of pediatric COVID-19. Patients with a severe and nonsevere clinical course were compared using the inverse variance heterogeneity model and odds ratio (OR) as the effect size. A sensitivity analysis was performed if the heterogeneity was high among studies.

RESULTS

A total of 811 studies were identified through a systematic search of which 55 studies (4369 patients) were included in this systematic review. The commonest GI symptoms were diarrhea-19.08% [95% confidence interval (CI) 10.6-28.2], nausea/vomiting 19.7% (95% CI 7.8-33.2) and abdominal pain 20.3% (95% CI 3.7-40.4). The presence of diarrhea was significantly associated with a severe clinical course with a pooled OR of 3.97 (95% CI 1.80-8.73; p < 0.01). Abdominal pain and nausea/vomiting were not associated with disease severity.

CONCLUSIONS

Diarrhea, nausea/vomiting or abdominal pain are present in nearly one-fifth of all children with COVID-19. The presence of diarrhea portends a severe clinical course.

Clinical characteristics, treatment and outcomes of paediatric COVID-19: a systematic review and meta-analysis

OBJECTIVE

Compare paediatric COVID-19 disease characteristics, management and outcomes according to World Bank country income level and disease severity.

DESIGN

Systematic review and meta-analysis.

SETTING

Between 1 December 2019 and 8 January 2021, 3350 articles were identified. Two reviewers conducted study screening, data abstraction and quality assessment independently and in duplicate. Observational studies describing laboratory-confirmed paediatric (0-19 years old) COVID-19 were considered for inclusion.

MAIN OUTCOMES AND MEASURES

The pooled proportions of clinical findings, treatment and outcomes were compared according to World Bank country income level and reported disease severity.

RESULTS

129 studies were included from 31 countries comprising 10 251 children of which 57.4% were hospitalised. Mean age was 7.0 years (SD 3.6), and 27.1% had a comorbidity. Fever (63.3%) and cough (33.7%) were common. Of 3670 cases, 44.1% had radiographic abnormalities. The majority of cases recovered (88.9%); however, 96 hospitalised children died. Compared with high-income countries, in low-income and middle-income countries, a lower proportion of cases were admitted to intensive care units (ICUs) (9.9% vs 26.0%) yet pooled proportion of deaths among hospitalised children was higher (relative risk 2.14, 95% CI 1.43 to 3.20). Children with severe disease received antimicrobials, inotropes and anti-inflammatory agents more frequently than those with non-severe disease. Subgroup analyses showed that a higher proportion of children with multisystem inflammatory syndrome (MIS-C) were admitted to ICU (47.1% vs 22.9%) and a higher proportion of hospitalised children with MIS-C died (4.8% vs 3.6%) compared with the overall sample.

CONCLUSION

Paediatric COVID-19 has a favourable prognosis. Further severe disease characterisation in children is needed globally.

Outcome of Children Admitted With SARS-CoV-2 Infection: Experiences From a Pediatric Public Hospital

OBJECTIVE

To study clinical characteristics and outcome of children with admitted to a paediatric hospital in Mumbai, India.

METHODS

Review of medical records of 969 children admitted between 19 March and 7 August, 2020, to assess the clinico-demographic characteristics, disease severity and factors predicting outcome in COVID-19 children. Variables were compared between children who were previously healthy (Group I) and those with co-morbidity (Group II).

RESULTS

123 (71 boys) children with median (IQR) age of 3 (0.7- 6) years were admitted, of which 47 (38%) had co-morbidities. 39 (32 %) children required intensive care and 14 (11.4%) died. Male sex, respiratory manifestation, oxygen saturation <94%; at admission, mechanical ventilation, inotrope, hospital stay of <10 days were independent predictors of mortality. Oxygen saturation <94% at admission (OR 35.9, 95% CI 1.5-856) and hospital stay <10 days (OR 9.1, 95% CI 1.04-99.1) were significant.

CONCLUSION

COVID-19 in children with co-morbidities causes severe disease. Association of mortality with oxygen saturation by pulse oximeter <94% on admission, and hospital stay <10 days, needs further evaluation.

Duration of Viral Clearance in Children With SARS-CoV-2 Infection in Rajasthan, India

OBJECTIVE

To study the clinical and laboratory profile and to assess period for viral clearance in COVID 19 children.

METHODS

We reviewed hospital records of children (<18 years) admitted from 1 April to 31 May, 2020 at a tertiary-care public hospital and identified those positive for severe acute respiratory syndrome corona virus (SARS-CoV-2) by RT-PCR of respiratory secretions.

RESULTS

81.2% of the 85 children studied were asymptomatic and 3 (8.5%) died. Severe lymphopenia (43.8%), raised C-reactive protein (93.8%), raised erythrocyte sedimentation rate (75%) and high (>500ng/mL) levels of D-dimer (37.5%) were common. Median (IQR) duration of viral shedding was 7 (5-10) days, with range of 2 to 45 days; 96.3% had viral clearance within 14 days.

CONCLUSIONS

Majority of children aged <18 years with SARS-CoV-2 infection had viral clearance within 14 days.

Paediatric COVID-19: Milder Presentation-A Silver Lining in Dark Cloud

OBJECTIVE

To assess the clinico-epidemiological profile of paediatric patients with Corona virus disease 2019 (COVID-19) infection during the pandemic.

METHODS

Clinico-epidemiological and laboratory profile of children between 1 month and 14 years were studied between 15 May and 31 July 2020, who had positive nasopharyngeal and oropharyngeal swab for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) by reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTS

A total of 30 children with median age of 10.5 years (8 months to 14 years) were included in the present study. Sixty percent were boys. Twenty-seven (90%) belonged to an urban area and all 30 children were from a containment area. All were belonging to Kuppuswamy upper lower and lower socioeconomic class. Twenty-one (70%) were asymptomatic. All children had a positive household contact. Symptomatic children had only mild symptoms of fever, dry cough and rhinitis. All were fully vaccinated as per age. Nine (30%) had anaemia. The mean leucocyte count was 7470 ± 2427 (4300-14 100). Leucocytosis was seen in 3 (9%) children. C-reactive protein was found to be raised in only 4 (13%) children. We did not find alteration in sense of smell and taste. No mortality was reported.

CONCLUSION

COVID-19 in paediatric patients is usually mild. Severe acute respiratory infection is not a major manifestation of COVID 19 infection in children. All children infected by the novel Corona virus-2 in this study, have a documented household contact.
