Assessing the causes of under-five mortality and proportion associated with pneumococcal diseases in Cameroon. A case-finding retrospective observational study: 2006-2012

Causes of infant and under-five (under-5) morbidity and mortality among hospitalized patients in Southern Nigeria: A hospital based study

Background

Rate and pattern of under-five mortality is a reflection of a society's healthcare system and quality of life. This study is aimed at reviewing the causes of infants and under-five morbidity and mortality in Calabar, Southern Nigeria.

Methods

This study used retrospective descriptive cross-sectional design. We did a retrospective collation of data on under-five morbidity and mortality from 2012 to 2017 of under-five patients admitted or died while in admission in University of Calabar Teaching Hospital. The causes of morbidity and mortality were reported based on International Classification of Diseases 10 (ICD-10). The morbidity, mortality and fatality rates were computed.

Results

A total of 11,416 under-five admissions and 391 deaths were recorded within the study period giving a fatality rate of 3.4%. Age 1-4 years category represented 50.5% of the admissions while infants (<1 year) constitute majority of the deaths (64.7%). There were 5652 infant admissions and 253 infant deaths giving fatality rate of 4.5% within the study period. Males constituted majority (55.8%) of under-five morbidity whereas females constituted majority (51.2%) of the deaths. Conditions originating from perinatal period; and infectious and parasitic diseases were the leading broad cause of under-five mortality. Specific disease analysis showed sepsis/septicemia; congenital infectious and parasitic diseases; slow fetal growth, malnutrition and short gestation as the chief causes of both infant and under-five mortality.

Conclusion

The leading causes of under-five deaths in the studied population are amenable. Improved healthcare and antenatal will be of immense benefit.

Improving access to health services through health reform in Lesotho: Progress made towards achieving Universal Health Coverage

In 2014 the Kingdom of Lesotho, in conjunction with Partners In Health, launched a National Health Reform with three components: 1) improved supply-side inputs based on disease burden in the catchment area of each of 70 public primary care clinics, 2) decentralization of health managerial capacity to the district level, and 3) demand-side interventions including paid village health workers. We assessed changes in the quarterly average of quality metrics from pre-National Health Reform in 2013 to 2017, which included number of women attending their first antenatal care visit, number of post-natal care visits attended, number of children fully immunized at one year of age, number of HIV tests performed, number of HIV infection cases diagnosed, and the availability of essential health commodities. The number of health centers adequately equipped to provide a facility-based delivery increased from 3% to 95% with an associated increase in facility-based deliveries from 2% to 33%. The number of women attending their first antenatal and postnatal care visits rose from 1,877 to 2,729, and 1,908 to 2,241, respectively. The number of children fully immunized at one year of life increased from 191 to 294. The number of HIV tests performed increased from 5,163 to 12,210, with the proportion of patients living with HIV lost to follow-up falling from 27% to 22%. By the end of the observation period, the availability of essential health commodities increased to 90% or above. Four years after implementation of the National Health Reform, we observed increases in antenatal and post-natal care, and facility-based deliveries, as well as child immunization, and HIV testing and retention in care. Improved access to and utilization of primary care services are important steps toward improving health outcomes, but additional longitudinal follow-up of the reform districts will be needed.

Research priorities for accelerating the achievement of three 95 HIV goals in Cameroon: a consensus statement from the Cameroon HIV Research Forum (CAM-HERO)

INTRODUCTION

the Treat-All remains the globally endorsed approach to attain the 95-95-95 targets and end the AIDS pandemic by 2030, but requires some country-level contextualization. In Cameroon, the specific research agenda to inform strategies for improving HIV policy was yet to be defined.

METHODS

under the patronage of the Cameroon Ministry of health, researchers, policy makers, implementing partners, and clinicians from 13 institutions, used the Delphi method to arrive at a consensus of HIV research priorities. The process had five steps: 1) independent literature scan by 5 working groups; 2) review of the initial priority list; 3) appraisal of priorities list in a larger group; 4) refinement and consolidation by a consensus group; 5) rating of top research priorities.

RESULTS

five research priorities and corresponding research approaches, resulted from the process. These include: 1) effectiveness, safety and active toxicity monitoring of new and old antiretrovirals; 2) outcomes of Antiretroviral Therapy (ART) with focus in children and adolescents; 3) impact of HIV and ART on aging and major chronic diseases; 4) ART dispensation models and impact on adherence and retention; 5) evaluations of HIV treatment and prevention programs.

CONCLUSION

the research priorities resulted from a consensus amongst a multidisciplinary team and were based on current data about the pandemic and science to prevent, treat, and ultimately cure HIV. These priorities highlighted critical areas of investigation with potential relevance for the country, funders, and regulatory bodies.

Burden of vaccine-preventable diseases, trends in vaccine coverage and current challenges in the implementation of the expanded program on immunization: A situation analysis of Cameroon

The discovery and development of vaccines remain one of the major successes of global health with millions of lives saved every year through routine vaccination. Although vaccines provide a safe and cost-effective solution to vaccine-preventable diseases (VPDs), VPDs are still a serious public health problem in most parts of the world, especially in sub-Saharan Africa (SSA) and Asia. In this review, we discuss the burden of VPDs and vaccine coverage several decades after the introduction of the Expanded Program on Immunization (EPI) in Cameroon. We also discuss how different factors affect the implementation of the EPI, highlighting context-specific factors such as the ongoing civil conflict in Cameroon, and the presence of other infectious diseases like COVID-19.

Impact of 13-valent pneumococcal conjugate vaccine on laboratory-confirmed pneumococcal meningitis and purulent meningitis among children ˂5 years in Cameroon, 2011-2018

BACKGROUND

The 13-valent pneumococcal conjugate vaccine (PCV13) entered Cameroon's childhood national immunization programme (NIP) in July 2011 under a 3-dose schedule (6, 10, 14 weeks of age) without any catch-up. We described the impact of PCV13 onserotype distribution among pneumococcal meningitis cases over time.

METHODS

We used laboratory-based sentinel surveillance data to identify meningitis cases among 2- to 59-month-old children with clinically-suspected bacterial meningitis (CSBM) admitted to hospitals in Yaoundé (August 2011-December 2018). Purulent meningitis cases had a cerebrospinal fluid (CSF) white blood cell (WBC) count ≥20 per mm3. Pneumococcal meningitis cases had S. pneumoniae identified from CSF, with serotyping by polymerase chain reaction. Years 2011-2014 were described as early PCV13 era (EPE) and years 2015-2018 as late PCV13 era (LPE) impact periods.

RESULTS

Among children hospitalized with CSBM who had a lumbar puncture obtained, there was no significant change from the EPE versus the LPE in the percentage identified with purulent meningitis: 7.5% (112/1486) versus 9.4% (154/1645), p = 0.0846. The percentage of pneumococcal meningitis cases due to PCV13 vaccine-serotype (VST) decreased from 62.0% (31/50) during the EPE to 35.8% (19/53) in the LPE, p = 0.0081. The most frequent pneumococcal meningitis VSTs during the EPE were 6A/6B (30%) and 5 (6%), and during the LPE were 14 (13.2%), 3 (7.6%), 4 (5.6%) and 18C (5.6%).

CONCLUSION

Four to seven years after PCV13 introduction, the proportion of pneumococcal meningitis due to vaccine serotypes has declined, mainly due to reductions of serotypes 6A/6B, 1, 19A, and 23F; nevertheless, PCV13 VSTs remain common. Because the analyzed surveillance system was not consistent or population based, we could not estimate incidence or overall impact; this emphasizes the need for improved surveillance to document further the utility of PCV13 immunization in Cameroon.
