    Childhood tuberculosis : progress requires advocacy strategy now
    (European Respiratory Society, 2012) Sandgren, Andreas; Cuevas, Luis E.; Dara, Masoud; Gie, Robert P.; Grzemska, Malgorzata; Hawkridge, Anthony; Hesseling, Anneke C.; Kampmann, Beate; Lienhardt, Christian; Manissero, Davide; Wingfield, Claire; Graham, Stephen M.
    Childhood tuberculosis (TB) is a preventable and curable infectious disease that remains overlooked by public health authorities, health policy makers and TB control programmes. Childhood TB contributes significantly to the burden of disease and represents the failure to control transmission in the community. Furthermore, the pool of infected children constitutes a reservoir of infection for the future burden of TB. It is time to prioritise childhood TB, advocate for addressing the challenges and grasp the opportunities in its prevention and control. Herein, we propose a scientifically informed advocacy agenda developed at the International Childhood TB meeting held in Stockholm, Sweden, from March 17 to 18, 2011, which calls for a renewed effort to improve the situation for children affected by Mycobacterium tuberculosis exposure, infection or disease. The challenges and needs in childhood TB are universal and apply to all settings and must be addressed more effectively by all stakeholders. It is estimated that of the nine million tuberculosis (TB) cases occurring every year worldwide, one million occur among children [1]. However, estimates of the burden of childhood TB are uncertain, and under-reporting and under-estimation of the global numbers are likely. In most settings, children with TB continue to be given low priority by National TB control Programmes (NTP) because they are less likely to transmit disease. Provision of more accurate data by national surveillance programmes is essential for improved global TB-burden estimates among children. Childhood TB has been largely absent from the global public health agenda despite being a major contributor to childhood morbidity and mortality particularly in high TB-burden settings and advocacy and scientific progress are still insufficient. Guidelines for childhood TB management have been developed and are already adopted by many countries. However, a wide policy/practice gap remains that needs to be addressed. Advocacy for the implementation and monitoring of these policies is, therefore, critical.

    Potentially modifiable factors associated with death of infants and children with severe pneumonia routinely managed in district hospitals in Malawi
    (Public Library of Science, 2015) Enarson, Penelope M.; Gie, Robert P.; Mwansambo, Charles C.; Chalira, Alfred E.; Lufesi, Norman N.; Maganga, Ellubey R.; Enarson, Donald A.; Cameron, Neil A.; Graham, Stephen M.
    Objective: To investigate recognised co-morbidities and clinical management associated with inpatient pneumonia mortality in Malawian district hospitals. Methods: Prospective cohort study, of patient records, carried out in Malawi between 1st October 2000 and 30th June 2003. The study included all children aged 0-59 months admitted to the paediatric wards in sixteen district hospitals throughout Malawi with severe and very severe pneumonia. We compared individual factors between those that survived (n = 14 076) and those that died (n = 1 633). Results: From logistic regression analysis, predictors of death in hospital, adjusted for age, sex and severity grade included comorbid conditions of meningitis (OR =2.49, 95% CI 1.50-4.15), malnutrition (OR =2.37, 95% CI 1.94-2.88) and severe anaemia (OR =1.41, 95% CI 1.03-1.92). Requiring supplementary oxygen (OR =2.16, 95% CI 1.85-2.51) and intravenous fluids (OR =3.02, 95% CI 2.13-4.28) were associated with death while blood transfusion was no longer significant (OR =1.10, 95% CI 0.77-1.57) when the model included severe anaemia. Conclusions: This study identified a number of challenges to improve outcome for Malawian infants and children hospitalised with pneumonia. These included improved assessment of co-morbidities and more rigorous application of standard case management.

    Reducing deaths from severe pneumonia in children in Malawi by improving delivery of pneumonia case management
    (PLoS, 2014-07-22) Enarson, Penelope M.; Gie, Robert P.; Mwansambo, Charles C.; Maganga, Ellubey R.; Lombard, Carl J.; Enarson, Donald A.; Graham, Stephen M.
    Objective: To evaluate the pneumonia specific case fatality rate over time following the implementation of a Child Lung Health Programme (CLHP) within the existing government health services in Malawi to improve delivery of pneumonia case management. Methods: A prospective, nationwide public health intervention was studied to evaluate the impact on pneumonia specific case fatality rate (CFR) in infants and young children (0 to 59 months of age) following the implementation of the CLHP. The implementation was step-wise from October 1st 2000 until 31st December 2005 within paediatric inpatient wards in 24 of 25 district hospitals in Malawi. Data analysis compared recorded outcomes in the first three months of the intervention (the control period) to the period after that, looking at trend over time and variation by calendar month, age group, severity of disease and region of the country. The analysis was repeated standardizing the follow-up period by using only the first 15 months after implementation at each district hospital. Findings: Following implementation, 47,228 children were admitted to hospital for severe/very severe pneumonia with an overall CFR of 9•8%. In both analyses, the highest CFR was in the children 2 to 11 months, and those with very severe pneumonia. The majority (64%) of cases, 2–59 months, had severe pneumonia. In this group there was a significant effect of the intervention Odds Ratio (OR) 0•70 (95%CI: 0•50–0•98); p = 0•036), while in the same age group children treated for very severe pneumonia there was no interventional benefit (OR 0•97 (95%CI: 0•72–1•30); p = 0•8). No benefit was observed for neonates (OR 0•83 (95%CI: 0•56–1•22); p = 0•335). Conclusions: The nationwide implementation of the CLHP significantly reduced CFR in Malawian infants and children (2–59 months) treated for severe pneumonia. Reasons for the lack of benefit for neonates, infants and children with very severe pneumonia requires further research.
