Community-acquired multidrug-resistant Enterobacter cloacae sepsis in a 25-month-old child in rural Gambia: A case report.

Enterobacter cloacae is the leading cause of morbidity and mortality in the genus Enterobacter. It mostly causes nosocomial infections, especially in children, the elderly and those with underlying diseases. However, cases of community-acquired bacteraemia caused by E. cloacae have been reported. The increasing inclination of E. cloacae to cause multidrug-resistant infections has made it particularly challenging to treat. A 25-month-old male child presented to a rural hospital in The Gambia with a one-week history of persistent high-grade fever, dyspnoea, and anorexia. Two days before presentation, he began to have generalized tonic-clonic seizures. On examination, he was found to be febrile, dyspnoeic, pale, and tachycardic. He had a modified Glasgow Coma Scale score of 9/15. Investigations revealed an elevated C-reactive protein, low haemoglobin, and elevated white blood cell count. Cerebrospinal fluid culture did not yield any growth. E. cloacae was isolated from a blood culture taken on the day of admission. The pathogen was resistant to all available antibiotics. He was transfused with whole blood and initially treated empirically with amoxicillin-clavulanic acid and gentamicin. The former was changed to cefuroxime because the child had not improved. The child died nine days after admission. Although E. cloacae is primarily known for causing nosocomial infections, fatal community-acquired infections also occur. This case report demonstrates the difficulty in treating multidrug-resistant E. cloacae in a low-resource setting and its propensity to cause fatal infections.

Ochrobactrum anthropi sepsis in a 15-month-old child: A case report.

Key Clinical Message: Ochrobactrum anthropi (O. anthropi), a rare opportunistic pathogen, caused sepsis in a malnourished 15-month-old African child. Early detection and appropriate antibiotics led to full recovery, highlighting the importance of robust surveillance for emerging pathogens in vulnerable populations. Abstract: While rarely causing infections, O. anthropi, a non-fermenting, obligately aerobic, flagellated gram-negative bacillus, demonstrates oxidase positivity and indole negativity. Traditionally, Ochrobactrum spp is considered a low threat due to its environmental abundance and mild virulence. It is, however, a multidrug-resistant bacteria known for causing opportunistic infections in humans. O. anthropi is typically associated with catheter-related bloodstream infections. The first documented case was in 1998; most cases have been reported in developed countries. We present a case of O. anthropi sepsis in a malnourished child in sub-Saharan Africa. We report a case involving a 15-month-old African female who presented with symptoms and signs of protein-energy malnutrition and sepsis. The blood culture revealed O.anthropi. We treated the child with the empirical first-line antibiotics per the national guidelines, intravenous ampicillin and gentamicin for a week, and the child fully recovered. This report describes a rare case of O. anthropi sepsis with malnutrition in an African female child. O. anthropi is an emerging pathogen causing opportunistic infections in both immunocompetent and immunocompromised patients. We report that early bacterial detection, appropriate antibiotic susceptibility and antimicrobial management based on local antibiogram data may be essential for excellent patient outcomes. Additionally, we recommend more robust surveillance to detect such rare emerging pathogens.

Stenotrophomonas maltophilia neonatal sepsis: a case report.

BACKGROUND: Stenotrophomonas maltophilia is a gram-negative bacteria known for causing opportunistic and nosocomial infections in humans. S. maltophilia is an emerging pathogen of concern due to it's increasing prevalence, diverse disease spectrum, intrinsic multi-drug resistance and high mortality rates in immunocompromised individuals. S. maltophilia is a rare cause of neonatal sepsis associated with significant morbidity and mortality. The bacterium's multi-drug resistance poses a considerable challenge for treatment, with various mechanisms contributing to its resistance. CASE PRESENTATION: We report a case involving a 40-h-old male African neonate who exhibited symptoms of neonatal sepsis. The blood culture revealed Stenotrophomonas maltophilia, which was sensitive to ciprofloxacin and gentamicin but resistant to other antibiotics. Lumbar puncture for CSF could not be done because the father declined. We treated the newborn with the empirical first-line antibiotics as per the national guideline intravenous ampicillin and gentamicin for six days, and the child recovered fully with a repeated negative blood culture. CONCLUSIONS: This report describes a neonatal sepsis case caused by S. maltophilia, a multi-drug resistant bacteria and a rare cause of neonatal sepsis. We report that early detection of the bacterial and antimicrobial management based on local antibiogram data may be essential for successful patient's management.

Impact of the COVID-19 pandemic on a clinical trial of pneumococcal vaccine scheduling (PVS) in rural Gambia.

The COVID-19 pandemic represents an unprecedented challenge for clinical research. The Pneumococcal Vaccine Schedules (PVS) study is a non-inferiority, interventional trial in which infants resident in 68 geographic clusters are randomised to two different schedules for pneumococcal vaccination. From September 2019 onwards, all infants resident in the study area became eligible for trial enrolment at all Expanded Programme on Immunisation (EPI) clinics in the study area. Surveillance for clinical endpoints is conducted at all 11 health facilities in the study area. PVS is conducted as a collaboration between the Medical Research Council Unit The Gambia (MRCG) at LSHTM and the Gambian Ministry of Health (MoH). The COVID-19 pandemic caused many disruptions to PVS. MRCG instructed interventional studies that participant enrolment be suspended on 26 March 2020, and a public health emergency was declared in The Gambia on 28 March 2020. Enrolment in PVS restarted on 1 July 2020 and was suspended again on 5 August 2020 after The Gambia experienced a sharp increase in COVID-19 cases in late July 2020 and restarted again on 1 September 2020. During periods of suspended enrolment of infants at EPI clinics, PVS continued safety surveillance at health facilities, albeit with disruptions. During the periods of suspended enrolment, infants who had been enrolled before 26 March 2020 continued to receive the PCV schedule to which they had been randomly allocated based on their village of residence, whereas all other infants received the standard PCV schedule. Throughout 2020 and 2021, the trial faced numerous technical and operational challenges: disruption to MoH delivery of EPI services and clinical care at health facilities; episodes of staff illness and isolation; disruption of MRCG transport, procurement, communications and human resource management; and also a range of ethical, regulatory, sponsorship, trial monitoring and financial challenges. In April 2021, a formal review concluded that the pandemic had not compromised the scientific validity of PVS and that the trial should continue as per protocol. The continuing challenges that COVID-19 poses to PVS, and other clinical trials will persist for some time.
