Simplified antibiotic regimens for young infants with possible serious bacterial infection when the referral is not feasible in the Democratic Republic of the Congo

Association of clinical signs of possible serious bacterial infections identified by community health workers with mortality of young infants in South Asia: a prospective, observational cohort study

Background

The World Health Organization (WHO) has developed guidance for community health workers (CHWs) in identifying sick young infants based on clinical signs. We conducted a prospective, observational cohort study to characterise mortality risk of young infants based on their clinical signs.

Methods

We conducted a population-based, prospective observational cohort study at five sites in Bangladesh (Sylhet, November 01, 2011-December 31, 2013), India (Vellore and Odisha, September 01, 2013-February 28, 2015), and Pakistan (Karachi, January 01, 2012-December 31, 2013; Matiari, March 01, 2012-December 31, 2013) to identify newborn infants who were followed-up by CHWs through 10 scheduled home visits over the first 60 completed days after birth to identify signs of possible serious bacterial infection (PSBI). We determined the frequency of signs and conducted Cox regression to investigate the association of signs with mortality risk within 7 days of identification of the signs.

Findings

CHWs made 522,309 visits to assess 63,017 young infants and found ≥1 sign(s) of PSBI at 14,245 visits (2.7%), including 5.8% (5568 of 96,390) and 1.8% (6635 of 365,769) of visits of infants 0-<3 and 7-<60 days of age, respectively. Each of the seven signs of PSBI when found alone was associated with significantly (p < 0.0001) increased risk for mortality, which increased further if any other additional sign of PSBI was found concurrently. Over the young infant period (days 0-<60) CHW identification of no movement or movement only on stimulation was associated with the highest risk for mortality [adjusted hazard ratio (aHR) 73.0, 95% confidence interval (CI) 44.4-119.9] followed by poor feeding (aHR 31.9, 95% CI 24.1-42.3) and hypothermia (<35.5 °C) (aHR 31.4, 95% CI 23.5-41.9). Hypothermia had particularly high risk for mortality during days 7-<60 (HR 45.1, 95% CI 27.6-73.4).

Interpretation

WHO reconsideration of hypothermia as a sign of critical illness is warranted. Implementation research is urgently needed to reduce infant mortality by ensuring immediate referrals and interventions for children identified early by CHWs with no movement or movement only on stimulation, hypothermia, or poor feeding, especially in resource-poor settings.

Incidence of possible serious bacterial infection in young infants in the three high-burden countries of the Democratic Republic of the Congo, Kenya, and Nigeria: A secondary analysis of a large, multi-country, multi-centre clinical trial

Background

Neonatal infections are a major public health concern worldwide, particularly in low- and middle-income countries, where most of the infection-related deaths in under-five children occur. Sub-Saharan Africa has the highest mortality rates, but there is a lack of data on the incidence of sepsis from this region, hindering efforts to improve child survival. We aimed to determine the incidence of possible serious bacterial infection (PSBI) in young infants in three high-burden countries in Africa.

Methods

This is a secondary analysis of data from the African Neonatal Sepsis (AFRINEST) trial, conducted in the Democratic Republic of the Congo (DRC), Kenya, and Nigeria between 15 March 2012 and 15 July 2013. We recorded baseline characteristics, the incidence of PSBI (as defined by the World Health Organization), and the incidence of local infections among infants from 0-59 days after birth. We report descriptive statistics.

Results

The incidence of PSBI among 0-59-day-old infants across all three countries was 11.2% (95% confidence interval (CI) = 11.0-11.4). The DRC had the highest incidence of PSBI (19.0%; 95% CI = 18.2-19.8). Likewise, PSBI rates were higher in low birth weight infants (24.5%; 95% CI = 23.1-26.0) and infants born to mothers aged <20 years (14.1%; 95% CI = 13.4-14.8). The incidence of PSBI was higher among infants delivered at home (11.7%; 95% CI = 11.4-12.0).

Conclusions

The high burden of PSBI among young infants in DRC, Kenya, and Nigeria demonstrates the importance of addressing PSBI in improving child survival in sub-Saharan Africa to reach the Sustainable Development Goals (SDGs). These data can support government authorities, policymakers, programme implementers, non-governmental organisations, and international partners in reducing preventable under-five deaths.

Optimal place of treatment for young infants aged less than two months with any low-mortality-risk sign of possible serious bacterial infection: Study Protocol for a randomised controlled trial from low- and middle-income countries

Background

World Health Organization (WHO) recommends hospitalisation and injectable antibiotics for clinical sepsis / possible serious bacterial infection (PSBI) in young infants up to two months of age. However, some young infants with low-mortality risk signs of PSBI may not require hospitalisation, for which evidence needs to be generated.

Methods

This is a protocol for a multicentre, individually randomised, open-label trial that will be conducted in seven sites in six countries Bangladesh, Ethiopia, India (two sites), Nigeria, Pakistan and Tanzania. All sites will use this common protocol with the same study design, inclusion of participants, intervention, comparison, and outcomes, as well as quality control and analysis procedures to contribute to the overall sample size. All young infants (age <60 days) presenting at study hospitals with any single low-mortality risk sign (high body temperature ≥38°C, severe chest indrawing, or fast breathing of ≥60 breaths per minute in <7 days old infants) will be randomised to either outpatient care with injectable gentamicin for two days and oral amoxicillin for seven days (intervention) or inpatient care with injection gentamicin plus injection ampicillin along with supportive treatment, where needed, for seven days (control). We plan to enrol 7000 eligible young infants, 3500 infants in each of the two study arms. A trained and standardised independent outcome assessor will visit all enrolled cases on days two, four, eight and 15 post-randomisation to assess the study outcomes in both intervention and control groups. The primary outcome of poor clinical outcome, defined as death within two weeks of initiation of treatment, deterioration during the 7-day treatment period, or persistence of the presenting sign at the end of the 7-day treatment period, will be compared to assess if the outpatient treatment leads to superior or at least non-inferior clinical outcome than inpatient treatment. The selected sites have extensive research experience. The methods and all study procedures will be harmonised through central training of research staff by WHO, standardisation exercises for clinical signs, central data coordination centre and internal and external monitoring. Continuous evaluation of the enrolment by the sites will be carried out through regular calls, databased monitoring, and site visits by WHO monitors. This trial has received ethical approvals from the WHO and local site institutional ethics committees.

Discussion

If the results show that young infants with any single low-mortality risk PSBI sign can be effectively and safely treated on an outpatient basis, it may substantially increase access to treatment for infants and families with poor access to health facilities. It may also reduce the human, financial and material costs to the health system and allow the currently overloaded health facilities to focus on more critically ill infants. This evidence will contribute toward making a case for reviewing the current WHO PSBI management guideline.
