Life expectancy and risk factors for early death in patients with severe thalassemia syndromes in South India.

In spite of advances in chelation therapy and screening of blood, mortality associated with the most common life-threatening noncommunicable disease of children in India, transfusion-dependent thalassemia (TDT), remains poorly defined. This study aims at estimating death rates and mortality risk factors associated with TDT. The clinical records of 1087 patients from 5 thalassemia centers in India were retrospectively analyzed from 2011 to 2018. Median patient age was 8.5 years, with 107 patients older than 18 years; 656 patients were male and 431 were female. Demographic details and clinical parameters were analyzed at presentation and at last visit. With 41 recorded deaths, actuarial survival at 26.9 years was 50%, and under-5 mortality was 7 times higher than in the general population. Patients with transfusion-transmitted infections (TTIs) had 3.4 times higher risk for death (P = .031). Serum ferritin higher than 4000 ng/dL had 4.6 times higher risk for mortality compared with ferritin lower than 1000 ng/dL (P = .00063). A hemoglobin drop lower than 2 g/dL per week had 7.7 times higher mortality risk compared with a drop of less than 1 g/dL per week (P < .0001). Social determinants (sex, economic status, and distance from center), splenectomy, and even cardiac complications were not associated with higher mortality risk. Main causes of death were infection, iron overload, TTIs, and allo-immunization. Patients who received more than 4 years of adequate care had more than 66% mortality risk reduction (P < .0001). TDT in India continues to result in high mortality. Ineffective transfusion, TTIs, and chelation continue to be the most significant risk factors. Comprehensive care in dedicated day care centers from early age is likely to improve outcomes.

The My Child Matters programme: effect of public-private partnerships on paediatric cancer care in low-income and middle-income countries.

In low-income and middle-income countries, an excess in treatment failure for children with cancer usually results from misdiagnosis, inadequate access to treatment, death from toxicity, treatment abandonment, and relapse. The My Child Matters programme of the Sanofi Espoir Foundation has funded 55 paediatric cancer projects in low-income and middle-income countries over 10 years. We assessed the impact of the projects in these regions by using baseline assessments that were done in 2006. Based on these data, estimated 5-year survival in 2016 increased by a median of 5·1%, ranging from -1·5% in Venezuela to 17·5% in Ukraine. Of the 26 861 children per year who develop cancer in the ten index countries with My Child Matters projects that were evaluated in 2006, an estimated additional 1343 children can now expect an increase in survival outcome. For example, in Paraguay, a network of paediatric oncology satellite clinics was established and scaled up to a national level and has managed 884 patients since initiation in 2006. Additionally, the African Retinoblastoma Network was scaled up from a demonstration project in Mali to a network of retinoblastoma referral centres in five sub-Saharan African countries, and the African School of Paediatric Oncology has trained 42 physicians and 100 nurses from 16 countries. The My Child Matters programme has catalysed improvements in cancer care and has complemented the efforts of government, civil society, and the private sector to sustain and scale improvements in health care to a national level. Key elements of successful interventions include strong and sustained local leadership, community engagement, international engagement, and capacity building and support from government.

Feasibility, efficacy, and adverse effects of outpatient antibacterial prophylaxis in children with acute myeloid leukemia.

BACKGROUND: Intensive chemotherapy for pediatric acute myeloid leukemia incurs the risk of infectious complications, but the benefits of antibiotic prophylaxis remain unclear. METHODS: In the current study, among 103 children treated on the AML02 protocol between October 2002 and October 2008 at St. Jude Children's Research Hospital, the authors retrospectively assessed the effect of antibiotic prophylaxis on the frequency of febrile neutropenia, clinically or microbiologically confirmed infections (including bacteremia), and antibiotic resistance, as well as on the results of nasal and rectal surveillance cultures. Initially, patients received no prophylaxis or oral cephalosporin (group A). The protocol was then amended to administer intravenous cefepime alone or intravenous vancomycin plus either oral cephalosporin, oral ciprofloxacin, or intravenous cefepime (group B). RESULTS: There were 334 infectious episodes. Patients in group A had a significantly greater frequency of documented infections and bacteremia (both P < .0001) (including gram-positive and gram-negative bacteremia; P = .0003 and .001, respectively) compared with patients in group B, especially viridans streptococcal bacteremia (P = .001). The incidence of febrile neutropenia without documented infection was not found to be different between the 2 groups. Five cases of bacteremia with vancomycin-resistant enterococci (VRE) occurred in group B (vs none in group A), without related mortality. Two of these cases were preceded by positive VRE rectal surveillance cultures. CONCLUSIONS: Outpatient intravenous antibiotic prophylaxis is feasible in children with acute myeloid leukemia and reduces the frequency of documented infection but not of febrile neutropenia. Despite the emergence of VRE bacteremia, the benefits favor antibiotic prophylaxis. Creative approaches to shorten the duration of prophylaxis and thereby minimize resistance should be explored.
