Molecular characterization of haemagglutinin genes of influenza B viruses circulating in Ghana during 2016 and 2017.

Recent reports of haemagglutinin antigen (HA) mismatch between vaccine composition strains and circulating strains, have led to renewed interest in influenza B viruses. Additionally, there are concerns about resistance to neuraminidase inhibitors in new influenza B isolates. To assess the potential impact in Ghana, we characterized the lineages of influenza B viruses that circulated in Ghana between 2016 and 2017 from different regions of the country: Southern, Northern and Central Ghana. Eight representative specimens from the three regions that were positive for influenza B virus by real-time RT-PCR were sequenced and compared to reference genomes from each lineage. A total of eleven amino acids substitutions were detected in the B/Victoria lineage and six in the B/Yamagata lineage. The strains of influenza B viruses were closely related to influenza B/Brisbane/60/2008 and influenza B/Phuket/3073/2013 for the Victoria and Yamagata lineages, respectively. Three main amino acid substitutions (P31S, I117V and R151K) were found in B/Victoria lineages circulating between 2016 and 2017, while one strain of B/Victoria possessed a unique glycosylation site at amino acid position 51 in the HA2 subunit. Two main substitutions (L172Q and M251V) were detected in the HA gene of the B/Yamagata lineage. The U.S. CDC recently reported a deletion sub-group in influenza B virus, but this was not identified among the Ghanaian specimens. Close monitoring of the patterns of influenza B evolution is necessary for the efficient selection of representative viruses for the design and formulation of effective influenza vaccines.

Sepsis among Neonates in a Ghanaian Tertiary Military Hospital: Culture Results and Turnaround Times.

In this study, we described the bacterial profile, antibiotic resistance pattern, and laboratory result turnaround time (TAT) in neonates with suspected sepsis from a tertiary-level, military hospital in Accra, Ghana (2017-2020). This was a cross-sectional study using secondary data from electronic medical records. Of 471 neonates clinically diagnosed with suspected sepsis in whom blood samples were collected, the median TAT from culture request to report was three days for neonates who were culture-positive and five days for neonates who were culture-negative. There were 241 (51%) neonates discharged before the receipt of culture reports, and of them, 37 (15%) were culture-positive. Of 471 neonates, twenty-nine percent (n = 139) were bacteriologically confirmed, of whom 61% (n = 85) had late-onset sepsis. Gram-positive bacterial infection (89%, n = 124) was the most common cause of culture-positive neonatal sepsis. The most frequent Gram-positive pathogen was coagulase-negative Staphylococcus (55%, n = 68) followed by Staphylococcus aureus (36%, n = 45), of which one in two were multidrug resistant. The reasons for large numbers being discharged before the receipt of culture reports need to be further explored. There is a need for improved infection prevention and control, along with ongoing local antimicrobial resistance surveillance and antibiotic stewardship to guide future empirical treatment.

Challenges with the pursuit of ISO 15189 accreditation in a public health laboratory in Ghana.

Background: Accreditation is important for all medical laboratories, particularly public health laboratories in developing countries. Several laboratories in Ghana implemented the requirements of the International Organization for Standardization (ISO) 15189 but were unable to proceed to accreditation. This article describes the challenges faced by the Pathology Division Laboratory of the 37 Military Hospital, Accra, Ghana, during the acquisition of ISO 15189 accreditation and suggests solutions for a better approach. Intervention: Following ISO 15189 accreditation in 2017, an online survey was conducted between 01 and 30 March 2020 among the laboratory staff. Respondents were required to grade, on a scale of 0 (least) to 5 (most), the extent to which 16 key challenges influenced the process of obtaining accreditation. Key informant interviews were also held with laboratory personnel who were directly involved in the establishment of the quality management system in the laboratory and the accreditation acquisition process. Lessons learnt: Documentation, laboratory safety measures, laboratory management support, and reagent unavailability were estimated as the challenges that most affected the acquisition of laboratory accreditation. Challenges such as poor communication, staff apathy and workload had the least effect on the accreditation process. There was no difference in challenges identified between persons who worked in the laboratory before or after accreditation (p = 0.11). Recommendations: To surmount the anticipated challenges, there is the need for national strategic direction for laboratory accreditation, hospital and laboratory management support for the accreditation acquisition and maintenance processes, and sufficient technical assistance in the form of training and mentorship.

COVID- 19 and sickle cell disease: autopsy findings of three deaths at the 37 Military Hospital, Accra, Ghana.

The main pathological effects of COVID-19 infection have been reported to occur in the lungs, with the most pronounced manifestation being reported as Adult Respiratory Distress Syndrome (ARDS) with thromboembolic phenomena. Sickle Cell Disease (SCD) is a common genetic disorder present in 2% of newborns in Ghana. The complications of SCD include Vaso-Occlusive Crisis and Acute Chest Syndrome, which primarily manifest in the lungs. The effects of SCD on the progression of COVID-19 have not been extensively and clearly documented in literature. The objective was to describe the clinical and pathological findings in three SCD patients who died of COVID-19 related complications. A complete autopsy was performed on each of the three SCD patients who were presumed to have COVID-19. Lung swabs were subsequently taken and tested for SARS-CoV-2. The differences in histopathological findings of the three cases were highlighted and correlation with clinical findings was also done. Lung histopathological findings for all three cases were consistent with Acute Respiratory Distress Syndrome (ARDS)/ Diffuse Alveolar Damage (DAD) described for infections with COVID-19 and lung swabs tested for SARS-CoV-2 by real time Reverse Transcription Polymerase Chain Reaction (rRT-PCR) were positive. Though SCD has been reported not to adversely affect an individual´s chance of worse outcome when infected with COVID-19, our findings suggest otherwise. We suggest that SCD may be an important co-morbidity that needs to be considered in COVID-19 patients and when present needs to be considered as an adverse risk for poor outcomes. Also, post-discharge anti-coagulation and monitoring should be encouraged. More autopsies are required to fully understand the pathogenesis of COVID-19 in SCD patients.

Postmortem diagnosis of COVID-19: Antemortem challenges of three cases at the 37 Military Hospital, Accra, Ghana.

BACKGROUND: Consistency among clinical symptoms, laboratory results and autopsy findings can be a quality measure in the diagnosis of coronavirus disease 2019 (COVID-19). There have been classic clinical cases that have met the case definition of COVID-19 but real-time reverse-transcription polymerase chain reaction (rRT-PCR) tests of nasopharyngeal swabs were negative. OBJECTIVES: This study aimed to share pathological observations of autopsies performed at the 37 Military Hospital's Department of Anatomical Pathology on three presumed COVID-19 cases in Accra, Ghana. METHOD: Complete autopsies with detailed gross and histopathological analysis were conducted between April 2020 and May 2020 on three suspected COVID-19 cases, of which two had initial negative (rRT-PCR) nasopharyngeal tests. Postmortem bronchopulmonary samples of two cases were collected and tested by rRT-PCR for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). RESULTS: The two postmortem bronchopulmonary samples tested for SARS-CoV-2 by rRT-PCR were positive. Though no postmortem bronchopulmonary sample was taken from the third case, a close contact tested positive for SARS-CoV-2 in later contact tracing. For all three cases, lung histopathological findings were consistent with Acute Respiratory Distress Syndrome. CONCLUSION: The outcome of COVID-19 testing is dependent on the sample type and accuracy of sampling amongst other factors. Histopathological findings vary and may be dependent on a patient's modifying factors, as well as the duration of infection. More autopsies are required to fully understand the pathogenesis of this disease in Ghanaians.

COVID-19 autopsy reports from the Ga-East Municipal and the 37 Military Hospitals in Accra, Ghana.

INTRODUCTION: Since the declaration of COVID-19 by the World Health Organisation (WHO) as a global pandemic on 11th March 2020, the number of deaths continue to increase worldwide. Reports on its pathologic manifestations have been published with very few from the Sub-Saharan African region. This article reports autopsies on COVID-19 patients from the Ga-East and the 37 Military Hospitals to provide pathological evidence for better understanding of COVID-19 in Ghana. METHODS: Under conditions required for carrying out autopsies on bodies infected with category three infectious agents, with few modifications, complete autopsies were performed on twenty patients with ante-mortem and/or postmortem RT -PCR confirmed positive COVID-19 results, between April and June, 2020. RESULTS: There were equal proportion of males and females. Thirteen (65%) of the patients were 55years or older with the same percentage (65%) having Type II diabetes and/or hypertension. The most significant pathological feature found at autopsy was diffuse alveolar damage. Seventy per cent (14/20) had associated thromboemboli in the lungs, kidneys and the heart. Forty per cent (6/15) of the patients that had negative results for COVID-19 by the nasopharyngeal swab test before death had positive results during postmortem using bronchopulmonary specimen. At autopsy all patients were identified to have pre-existing medical conditions. CONCLUSION: Diffuse alveolar damage was a key pathological feature of deaths caused by COVID-19 in all cases studied with hypertension and diabetes mellitus being major risk factors. Individuals without co-morbidities were less likely to die or suffer severe disease from SARS-CoV-2. FUNDING: None declared.
