We herein report a case of a child with tuberculous meningitis and COVID-19 coinfection complicated by hydrocephalus, arterial ischaemic stroke and extensive cerebral sinus venous thrombosis. Both conditions induce a proinflammatory cytokine drive resulting, among others, in a prothrombotic state. The disruption of the coagulation system in this case was supported by elevated D-dimers, fibrinogen and ferritin levels, consistent with thrombotic complications reported in some adult patients infected with COVID-19. The child also exhibited prolonged viral shedding that suggests severe disease.

Background Tuberculosis (TB) continues to result in high morbidity and mortality in children from resource-limited settings. Diagnostic challenges, including resource-intense sputum collection methods and insensitive diagnostic tests, contribute to diagnostic delay and poor outcomes in children. We evaluated the diagnostic utility of stool Xpert MTB/RIF (Xpert) compared with bacteriologic confirmation (combination of Xpert and culture of respiratory samples). Methods In a hospital-based study in Cape Town, South Africa, we enrolled children younger than 13 years of age with suspected pulmonary TB from April 2012- August 2015. Standard clinical investigations included tuberculin skin test, chest radiograph and HIV testing. Respiratory samples for smear microscopy, Xpert and liquid culture included gastric aspirates, induced sputum, nasopharyngeal aspirates and expectorated sputum. One stool sample per child was collected and tested using Xpert. Results Of 379 children enrolled (median age, 15.9 months, 13.7% HIV-infected), 73 (19.3%) had bacteriologically confirmed TB. The sensitivity and specificity of stool Xpert vs. overall bacteriologic confirmation were 31.9% (95% CI 21.84-44.50%) and 99.7% (95% CI 98.2-100%) respectively. 23/51 (45.1%) children with bacteriologically confirmed TB with severe disease were stool Xpert positive. Cavities on chest radiograph were associated with Xpert stool positivity regardless of age and other relevant factors (OR 7.05; 95% CI 2.16-22.98; p=0.001). Conclusions Stool Xpert can rapidly confirm TB in children who present with radiologic findings suggestive of severe TB. In resource-limited settings where children frequently present with advanced disease, Xpert on stool samples could improve access to rapid diagnostic confirmation and appropriate treatment.

Airway compression was more severe in infants and most commonly involved the bronchus intermedius. Numerous parenchymal complications were documented, all showing right-side predominance.

Diagnostic imaging plays a significant role in both the diagnosis and treatment of complications of pneumonia in children and chest radiography is the imaging modality of choice. Computed tomography (CT) on the other hand, is not currently a first-line imaging tool for children with suspected uncomplicated community-acquired pneumonia and is largely reserved for when complications of pneumonia are suspected or there is difficulty in differentiating pneumonia from other pathology. This review outlines the situations where CT needs to be considered in children with pneumonia, describes the imaging features of the parenchymal and pleural complications of pneumonia, discusses how CT may have a wider role in developing countries where human immunodeficiency virus (HIV) and tuberculosis are prevalent, makes note of the role of CT scanning for identifying missed foreign body aspiration and, lastly, addresses radiation concerns.

Background Children seem relatively protected from serious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) related disease, but little is known about children living in settings with high tuberculosis and HIV burden. This study reflects clinical data on South African children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods We collected clinical data of children aged younger than 13 years with laboratory confirmed SARS-CoV-2 presenting to Tygerberg Hospital, Cape Town between 17th of April and 24th of July 2020. Results Hundred and fifty-nine children (median age 48·0 months (interquartile range, IQR 12·0-106·0)) were included. Hospitalized children (n=62), median age of 13·5 months (IQR 1·8-43·5) were younger than children not admitted (n=97), median age 81·0 months (IQR 34·5-120·5, p< 0·01). Thirty-three of 159 (20·8%) children had pre-existing medical conditions. Fifty-one of 62 (82·3%) hospitalized children were symptomatic; lower respiratory tract infection was diagnosed in 21/51 (41·2%) and 11/16 (68·8%) children younger than 3 months of age. Respiratory support was required in 25/51 (49·0%) children; 13/25 (52·0%) children were younger than 3 months. One child was HIV infected and 11/51 (21·2%) were HIV exposed uninfected and 7/51 (13·7%) children had a recent or new diagnosis of tuberculosis. Conclusion Children less than 1 year of age hospitalized with SARS-CoV-2 in Cape Town frequently required respiratory support, the access to oxygen may be limited in some LMICs which could potentially drive morbidity and mortality. HIV infection was uncommon but a relationship between HIV exposure, tuberculosis and SARS-CoV-2 should be explored.

BAL Xpert resulted in additional diagnostic yield and also in the rapid detection of drug resistance in children with complicated intrathoracic TB. The clinical impact of this modality should be further evaluated in children.

A cohort of 24 children with expansile pneumonia caused by Mycobacterium tuberculosis is described in mostly HIV-noninfected children (n = 22). The children presented with nonresolving pneumonia and a swinging fever (83%). On chest radiography, they had dense opacification with bulging fissures mainly in the upper lobes (75%). On computed tomography, the lobes are consolidated, with areas of liquefacation. Other features visible are enlarged mediastinal lymph adenopathy with ring enhancement (100%), cavities (63%), and tracheal compression (71%). On bronchoscopy, bronchi were obstructed by more than 75% in 20 (83%) of cases. Lymph gland enucleation was required in 42% of cases. Phrenic nerve palsy was present in 3 children, of whom 2 underwent diaphragmatic plication. The children received standard antituberculous therapy, to which prednisone (2 mg/kg/day) was added for 1 month. The mortality was 4% after 6 months of therapy.

Of the ventilated infants failing to respond to treatment, 72% had histologically confirmed CMV pneumonia, probably accounting for the high mortality in this cohort. The incidence of CMV disease in HIV infected infants being ventilated for severe pneumonia warrants that ganciclovir is used empirically until CMV disease is excluded. The role of lung biopsy in these circumstances needs to be researched.
