Impact of a quality improvement intervention on neonatal mortality in a regional hospital in Burkina Faso

Background The neonatal period is the most vulnerable time in terms of a child’s survival, with mortality during this period accounting for approximately half of the deaths before the age of 5 years. The Neonatal Essential Survival Technology (NEST) project is a program aiming to reduce mortality by improving the quality of neonatal care in sub-Saharan Africa. This study presents the evaluation of the first phase of the NEST intervention program at Saint Camille Hospital Ouagadougou (HOSCO), Burkina Faso, in terms of the reduction in neonatal mortality. Methods This is a retrospective analysis, based on “pre-intervention” data collected in 2015, and “post-intervention” data collected in 2018, including all infants admitted to the neonatal unit of HOSCO. The intervention period (2016 and 2017) comprised a structured quality improvement process conducted by a multidisciplinary working group that focused on improving infrastructure, equipment, training and use of clinical protocols, team working within the neonatal unit and with other hospital departments, and communication with referring healthcare facilities. Mortality data were compared pre- vs. post-intervention using a logistic regression model. Results The analysis included 1427 infants in the pre-intervention period, and 819 post-intervention. In both time periods, more than 75% of admissions were infants with low birth weight, and nearly 50% were very low birth weight. Post-intervention, while there was a decrease in overall admission, the proportion of multiple births increased from 20% to 24% (p = .01). The overall mortality rate was 44.9% (641/1427) pre-intervention, and 42.2% (346/819) post-intervention (OR 0.90, 95% confidence interval (CI) 0.76–1.07; p = .23). Adjusting for clinically relevant factors, the intervention was not associated with a change in overall mortality (OR 1.39, 95% CI 0.91–2.12; p = .13), but was associated with a reduced likelihood of mortality in outborn infants compared to inborn infants (OR 0.57, 95% CI 0.36–0.92; p = .02). Conclusions The first phase of the NEST quality improvement program was associated with a decrease in mortality in outborn infants admitted to the neonatal unit at HOSCO. Long-term assessment is expected to provide a more comprehensive evaluation of the program in a low-income setting.

First detection of mutated ERG11 gene in vulvovaginal Candida albicans isolates at Ouagadougou/Burkina Faso

BackgroundVulvovaginal candidiasis is an important cause of morbidity among women due to Candida species. In the last decades, resistance to azoles, first-line antifungals has increased. One molecular mechanism of azole resistance by Candida involves mutations in the ERG11 gene encoding lanosterol 14-α-demethylase, the target enzyme. This study was conducted to identify the clinical Candida species associated in vulvovaginal candidiasis; to determine the rate of antifungal resistance among Candida albicans isolates and to determine mutated ERG11 gene at Saint Camille Hospital in Ouagadougou, Burkina Faso.MethodsAntifungals susceptibility were performed using Kirby–Bauer disk diffusion method. ERG11 gene was detected using conventional PCR in C. albicans isolates resistant to at least one azole.ResultsOut of 262 clinical strains isolated, C. albicans accounted for 59.90%, followed by Candida glabrata 27.86%, Candida famata 7.25%, Candida tropicalis 3.05% and Saccharomyces cerevisiae 1.91%. Resistance rate of fluconazole to C. albicans was 59.54%. ERG11 gene was found in 9.79% of 92 C. albicans strains resistant to azoles.ConclusionsThis detection of mutated ERG11 gene in C. albicans is the first in Burkina Faso and may be a cause of azole resistance in recurrent Candida vulvovaginitis.

Isolation and Identification of Escherichia coli and Klebsiella pneumoniae Strains Resistant to the Oxyimino-Cephalosporins and the Monobactam by Production of GES Type Extended Spectrum Bêta-Lactamase (ESBL) at Saint Camille Hospital Center in Ouagadougou, Burkina Faso.

BackgroundBacterial resistance to beta lactamins is a real public health problem as it complicates treatment strategies. Several types of beta lactamase confer this resistance. Numerous studies report a high prevalence of ESBL producers among Gram-negative bacilli. The objective of this work was to identify the presence of the resistance gene GES in strains of E. coli and K. pneumoniae in Burkina Faso.MethodsDuring this study 39 strains of E. coli and K. pneumoniae resistant to oxyimino-cephalosporin and monobactam were collected in several samples and analyzed to determine the presence of the beta lactamase resistance gene BlaGES by classic PCR.ResultsIn the present study, resistant strains were observed in 21 E. coli and 18 K. pneumoniae. Among producers of ESBL isolates, the presence of the GES gene was detected up to 63% in E. coli and 37% in K pneumoniae.ConclusionThis study highlighted the presence of the GES gene in strains of E. coli and K. pneumoniae resistant to oxyimino-cephalosporin and monobactam in Burkina Faso. This highlights the presence of new ESBL in Burkina, which is of great interest for the proper care of patients and the control of resistance to antibiotics.

Dengue Immunological Markers Evolution at Saint Camille Hospital in Ouagadougou (HOSCO) Burkina Faso

<b>Background and Objective:</b> Dengue is a remerging vector-borne viral disease in Burkina Faso since the outbreak of 2013 and requires special attention from health authorities. This study reports the prevalence of dengue fever serological markers (NS1Ag, IgM and IgG) and infection dynamic from January, 2018 to December, 2020 among patients tested for dengue infection at Saint Camille Hospital of Ouagadougou (HOSCO). <b>Materials and Methods:</b> The study population consisted of 6414 patients aged 0-97 years. Dengue virus infection was detected in serum or plasma using the SD bioline dengue duo rapid detection kit. <b>Results:</b> The prevalence of dengue NS1Ag was 2.25% (45/2003), 18.43% (501/2719) and 2.42% (38/1569) in the study population in 2018, 2019 and 2020, respectively. The age groups over 50 years and 15-20 years were significantly more infected compared to the group 21-30 years respectively in 2019 (p = 0.030) and 2020 (p = 0.035). Patients tested positive for at least one of these markers (NSlAg, IgG and IgM) represented 26.01% (521/2003) and 38.98% (1060/2719). The peak of infection during 2018 and 2019 was observed between October and November. The present study reports a high seroprevalence of acute dengue virus infection. The presence of NS1Ag, IgM and IgG in patients suggests an active circulation of the dengue virus in Ouagadougou. <b>Conclusion:</b> Data shows recurrent outbreaks of dengue infection in our country need strong surveillance and a suitable and affordable diagnostic system to clarify the burden, pinpoint the risk factors and for better case management.

Social perceptions of malaria and diagnostic-driven malaria treatment in Burkina Faso

Malaria is a parasitic disease, endemic in many tropical and sub-tropical countries. Malaria is a well-known disease, familiar to almost all people in endemic regions, as they or their family are regularly confronted with it; everyone in these regions has probably experienced the disease, at least once in their life. To investigate the social perceptions of malaria in Burkina Faso, including its diagnosis-driven treatment, we have conducted a survey in both urban (Saint Camille Hospital, Ouagadougou HOSCO) and rural (Boussé Hospital) areas. Fifty-six individuals, mostly representatives of the society variability, were surveyed by questionnaires and 2 focus groups were organized with traditional healers. In general, populations seem to have grasped the causes, symptoms and means of preventing the disease. However, the majority of interviewees make a marked confusion between malaria and dengue; dengue fever is considered like a severe form of malaria. The care modalities (modern and/or traditional medicine) are plural and the choice of therapeutic practice depends on both the socio-economic conditions and education level of the patient. Whereas some patients mark preferences for one type of medicine, others simultaneously recourse to both; for these, a medicine does not outperform the other and their combination multiplies the chances of a quick recovery. Whether for modern or traditional medicine, the diagnosis is considered very important for effective disease management. Modern medicine uses diagnostic tools based on light microscopy and immunochromatography (rapid diagnostic tests; RDT); traditional medicine has its own diagnostic logic but nevertheless recognizes modern medicine diagnosis to guide its therapy.90 % of those interviewed first use modern medicine to seek an accurate diagnosis of their disease and thus to receive adequate treatment. Presumptive treatments are still widely prescribed and accepted by most patients who trust the judgment of their caregiver, not perceiving any benefit to an objective diagnosis. In front of a negative diagnosis, patient reactions are diverse, some accepting investigations for other diseases (45 %), others opting for self-medication (15 %), others resorting to traditional medicine (20 %).All are unanimous in the importance of diagnosis and are in favor of in-development diagnostic technologies, provided these obviously meet the features of reliability, ease of use, availability and, of course, economical accessibility.

First detection of the hemizygote frameshift variant of the DMD gene in a 13-year-old patient affected by dystrophinopathy (Duchenne DMD and Becker BMD) at Saint Camille Hospital of Ouagadougou, Burkina Faso: Case report

Genetic diseases are poorly reported in sub-Saharan Africa, especially in Burkina Faso. The reasons for this reality are multifactorial including, the difficulty of diagnostic confirmation, financial accessibility and even the difficulty with referral of cases by medical staff. Genetic diseases, although relatively rare, exist in families and deserve special attention in our paraclinical assessments. Few cases can be diagnosed in sub-Saharan Africa. The clinical case we are reporting here is a dystrophynopathy by mutation of the Duchenne muscular dystrophy (DMD) gene. This is the first confirmed detection of a frameshift mutation in the DMD gene in a boy received at Saint Camille Hospital in Ouagadougou, Burkina Faso. This is a 13-year-old MR boy, from a family of four siblings, all male, from the eastern region of Burkina Faso. The boy had a clinical picture of myopathy with difficulty in walking, frequent falls, myogenic syndrome with stool sign, Gowers sign and scapula alata, all leading to a suspicion of dystrophinopathy with a request for genetic analysis. The DMD gene responsible for the disease is located on the X chromosome (Xp21.2-p21.1). The study of the dystrophin gene (DMD) was done using three methods, namely MLPA, high throughput sequencing and Sanger sequencing. The results led to the identification of a frameshift mutation of exon 71 in the DMD gene: it is a hemizygotic variant with ribosomal shift of the DMD gene NM_004006.2 (DMD): c.10258del p.(Ser3420Leufs*25). This clinical case led for the first time in Burkina Faso to the confirmed diagnosis of hereditary muscular dystrophy resulting from a mutation with a frameshift in exon 71 of the DMD gene in the hemizygotic state in a 13-year-old boy, a student and the eldest sibling of 4 boys, three of whom have myopathy. Key words: Mutation, Duchenne muscular dystrophy (DMD) gene, dystrophinopathy, duchenne versus becker, case report.

Risk Factors for Neonatal Mortality at St Camille Hospital in Ouagadougou, Burkina Faso

Background: Neonatal mortality remains a public health concern in developing countries such as Burkina Faso. Improving the survival rate of newborns requires a good knowledge of the current situation. This study aimed at determining the risk factors for neonatal mortality in the Neonatology Department of Saint Camille Hospital of Ouagadougou (HOSCO - Hopital Saint Camille de Ouagadougou). Materials and Methods: This was a retrospective, descriptive and analytical study that included all newborns hospitalized in the neonatology department, at St Camille Hospital, in Burkina Faso from January 1 to December 31, 2017. Total of 710 records of hospitalized newborns in 2017 were analyzed. Among them our study focused on cases of death. Results: The neonatology department registered 246 deaths out of 710 hospitalizations, representing a mortality rate of 34.6%, of whom 194 (78.8%) were preterm infants and 52 (11.2%) were term newborns. Among the deceased newborns, 88% had a low birth weight and the sex ratio was 0.8. November was the most fatal period (12.6%). Prematurity and respiratory distress were the main reasons for referral. Prematurity (76.4%), asphyxia (51.2%) and neonatal infection (27.2%) were the top 3 diagnoses at admission. The leading cause of death was respiratory distress (89.8%). All the newborns have been hospitalized within 24 hours of life and the average time to death in the unit was 3 days and 54% of deaths occurred within 72 hours of hospitalization. Conclusion: Mortality rate is higher among preterm infants while it is relatively low among full-term newborns in our facility. Prematurity, asphyxia and neonatal infection remain the main risk factors associated with neonatal mortality.

Coexistence between the TOHO-type and Brazilian extended-spectrum (BES)-type of extended-spectrum β-lactamase (ESBL)-produced by bacteria caused public health issue. Several studies have been reported on the coexistence between blaTEM, blaCTX-M and blaSHV genes in ESBL in broad spectrum enterobacteria. The present study involved the prevalence of coexistence of blaTOHO and blaBES genes in enterobacteria identified in hospitalized and out-patients at Saint Camille Hospital in Ouagadougou (Burkina Faso). Firstly, the study was led by microbiological identification of enterobacteria, secondly antibiogram was performed by diffusion method and finally the molecular characterization was done by conventional polymerase chain reaction (PCR) to search for antibiotic resistance genes blaTOHO and blaBES. The ultraviolet (UV) lamp (Gene Flash) for the photography of gels allowed the visualization of specific bands of TOHO and BES genes. Among 250 strains of Gram negative bacilli collected, 60 strains (24.1%) showed resistance profile to antibiotics used. Molecular characterization showed the coexistence between blaTOHO and blaBES genes in 53.3% in bacteria strains carried by the patients. The highest prevalence was observed in Escherichia coli (34.4%) and Klebsiella pneumoniae (21.9%) strains. For the first time in Ouagadougou, Burkina Faso, this study therefore established the coexistence between blaTOHO and blaBES genes in ESBL produced enterobacteria at Saint Camille Hospital. Key words: Antibiotic, resistance, extended-spectrum β-lactamase (ESBL), genes, TOHO, Brazilian extended-spectrum (BES).

Contribution of Laser Photovaporisation in the Management of Lower Urinary Tract Symptoms Related to Prostatic Tumours: Preliminary Study of 29 Cases at the Saint Camille Hospital of Ouagadougou (Burkina Faso)

The treatment of prostatic tumour-related lower urinary tract symptoms (LUTS) uses a varied therapeutic arsenal. In our country, the treatment is dominated by open surgery. Laser treatment is becoming an efficient alternative to trans-urethral prostatic resection or prostatic adenomectomy. We report our experience with the results of Thulium laser photovaporization in the treatment of prostatic tumour-related LUTS. Materials and Methods: A prospective study was conducted between November 2018 and August 2019 at the Saint Camille hospital of Ouagadougou. The inclusion criteria were the presence of LUTS related to a prostatic tumour with an operative indication. Results: 29 patients were treated with Thulium laser prostatic photovaporization. The average age of patients was 72.58 ± 25.34 years (54 - 84 years). The average vaporization duration was 71.24 ± 21.65 minutes (15 - 210 minutes) for an average prostatic volume of 80.97 ml. The average duration of hospitalization for patients was 1.93 days (1 - 5 days). The average bladder sounding duration was 1.68 days (1 - 4 days). A capsular perforation, a sphincter lesion and urinary retention after removal of the catheter were the complications. Conclusion: Laser photovaporization is a newly used method at the Saint Camille Hospital. The benefit is the reduction of the risk of bleeding, the short duration of hospital stay and bladder sounding. Photovaporization deserves to be popularized in our daily practices.

Holmium Laser Ureteroscopy in the Treatment of the Upper Urinary Tract Stones: Concerning 54 Cases in the Surgical Department of the Saint Camille Hospital of Ouagadougou (Burkina Faso)

The treatment of urinary stones uses a varied therapeutic arsenal. Nowadays the mini-invasive techniques are the most used. We report our first experience on the results of flexible and semi-rigid ureteroscopy in the treatment of the upper urinary tract stones. Materials and Methods: A 20-month prospective study on flexible laser ureteroscopy was conducted at the Saint Camille Hospital of Ouagadougou. The inclusion criteria were for patients who had given informed consent and the presence of an unilateral obstructive upper urinary tract stone with an indication of surgical management. Results: 54 patients were treated with Holmium laser photo vaporization between January 2018 and August 2019. The average age of patients was 37.74 ± 17 years (11 - 83 years). The men were predominant at 55.56%, or a sex-ratio of 1.25. The average size of stones of 17.55 mm ± 4.16 mm (11 mm to 25 mm) with pyelic, ureteral and calyceal localization in respectively 42.6%, 33.3% and 24.1% of cases. The average duration of the interventions was 77.92 ± 43.57 minutes (11 to 180 minutes). We used drainage in 90.91% of the cases. The average duration of hospitalization was 1.2 ± 0.73 days with extremes ranging from one day to 6 days. The vaporization without residual fragment which is a success was 78.46%. Conclusion: Laser ureteroscopy is a newly used method at the Saint Camille hospital. The achievement of good results and its low morbidity encourage us to promote its extension and its use in sub-Saharan African hospitals.

Several studies have been reported on the blaTEM, blaCTX-M and blaSHV genes in Extended-spectrum β-lactamase (ESBL) producing Enterobacteria, however very few studies reported in the literature are related to blaBES in ESBL producing Enterobacteria. This study concerns the molecular epidemiology of the blaBES gene in Enterobacteria identified from in-patients and out-patients at Saint Camille hospital of Ouagadougou (Burkina Faso). The study was first involved microbiological identification of Enterobacteria that are implicated in antibiotic resistance using API 20 E system; the antibiotics susceptibility test was secondly performed by the diffusion method and the molecular characterization was finally made by PCR to detect the blaBES gene. Data were entered and analyzed using Excel 2013 and EPI Info version 6.0 software. A p-value < 0.05 was considered as significant. A total of 60 isolates of ESBL-producing Enterobacteria were found: 21 (35%) Escherichia coli; 18 (30%) Klebsiella pneumoniae; 6 (10%) Enterobacter cloacae; 4 (7%) Proteus mirabilis; 4 (7%) Serratia marcescens; 3 (5%) Citrobacter freundii; 1 (1.6%) Enterobacter aerogenes; 1 (1.6%) Citrobacter brakii; 1 (1.6%) Citrobacter youngae and 1 (1.6%) Salmonella arizonae. Molecular characterization revealed the presence of the blaBES gene in 38 (63.3%) of bacterial isolates carried by patients. The presence of blaBES gene in ESBL producing Enterobacteria at Saint Camille Hospital in Ouagadougou was therefore established in this study for the first time in Burkina faso.   Key words: Enterobacteria, Extended-spectrum β-lactamase (ESBL), blaBES, gene, hospital, resistance, Ouagadougou.

Imaging Findings of Children Stroke in Burkina Faso and Etiological Approach

Introduction: Stroke is defined as a sudden onset focal neurological deficit of presumed vascular origin. Although it is essentially adult and elderly condition, stroke can occur in children. Their diagnosis essentially radiological is based on two main imaging modalities namely Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI). Our study aimed to study radiological features of stroke in children with an etiologic approach in three health facilities of Ouagadougou. Material and Method: We conducted a retrospective study with descriptive focus during 11-year period from January 1st, 2006 to September 1st, 2017 among children aged between 02 months and 16 years who underwent brain CT scan and/or MRI; in whom diagnosis of stroke had been established in radiology department of Yalgado Ouedraogo Teaching Hospital (CHU-YO), Schiphra Methodist Medical Center (CM Schipphra) and Saint Camille Hospital of Ouagadougou (HOSCO). Results: 40 cases of pediatric stroke were collected including 23 at HOSCO, 15 at CHU-YO and 03 at CM Schipphra. Mean age was 6.45 years, with extremes of 2 months and 192 months. Unilateral contralateral motor weakness was the most common clinical presentation (32.5%) followed by seizures (17.5%). Ischemic stroke dominated in 82.5% of cases. Sino-venous thrombosis was rare and suspected in only one case. Sylvian artery was mostly affected in ischemic stroke for 56.25% of patients. The main etiologic factors found were hematologic (67.50%) then infectious factors (25%). Sickle cell disease was always incriminated in hematologic factor. Homozygous SS patients were the most numerous (82%). Conclusion: Stroke diagnosis in children is based on etiologic investigation, biology with a major role of medical imaging. Sickle cell disease accounts a lot in occurrence of stroke in children in our context.

Human immunodeficiency virus type 1 drug resistance in a subset of mothers and their infants receiving antiretroviral treatment in Ouagadougou, Burkina Faso.

The emergence of HIV-1 drug resistance (HIVDR) is a public health problem that affects women and children. Local data of HIVDR is critical to improving their care and treatment. So, we investigated HIVDR in mothers and infants receiving antiretroviral therapy (ART) at Saint Camille Hospital of Ouagadougou, Burkina Faso. This study included 50 mothers and 50 infants on ART. CD4 and HIV-1 viral load were determined using FACSCount and Abbott m2000rt respectively. HIVDR was determined in patients with virologic failure using ViroSeq HIV-1 Genotyping System kit on the 3130 Genetic Analyzer. The median age was 37.28 years in mothers and 1.58 year in infants. Sequencing of samples showed subtypes CRF02_AG (55.56%), CRF06_cpx (33.33%) and G (11.11%). M184V was the most frequent and was associated with highlevel resistance to 3TC, FTC, and ABC. Other mutations such as T215F/Y, D67N/E, K70R, and K219Q were associated with intermediate resistance to TDF, AZT, and 3TC. No mutation to LPV/r was detected among mothers and infants. The findings of HIVDR in some mothers and infants suggested the change of treatment for these persons.

Risk Factors Associated with Mother-to-Child Transmission of HIV-1, Spontaneous Abortion and Infant Mortality in HIV-1 Infected Women in Burkina Faso: A Prospective Study

Background: Despite efforts to fight, HIV/AIDS mother-to-child transmission of HIV-1 (MTCT), as well as abortion and infant mortality, remains a problem in sub-Saharan Africa. Indeed, a low level of CD4 and a high viral load can be associated with these situations. The aim of this study was to determine the risk factors associated with the occurrence of MTCT, spontaneous abortion and infant mortality in HIV-1 infected women in Ouagadougou, Burkina Faso. This was a prospective study conducted from May 2014 to September 2017 and involved 423 HIV-1 infected women followed at Saint Camille Hospital in Ouagadougou, Burkina Faso. Sociodemographic data were collected through a questionnaire. The CD4 count and HIV-1 viral load were determined using respectively BD FACSCount and Abbott m2000rt instruments. Bivariate analysis and multinomial logistic regression were performed for associations with a significance threshold for p < 0.05. Results: The average age of women was 38.75 ± 7.98 years. Rates of MTCT, abortion and infant mortality were 16.31%, 30.49% and 34.75%, respectively. The number of pregnancies was associated with the number of infant deaths (p = 0.002). A correlation between the number of pregnancies and infant mortality was observed (p = 0.002) with a relatively high rate (28.6%) among women who had three pregnancies. In addition, marital status was associated with HIV-1 infection in infants (p = 0.042) and spontaneous abortion (p = 0.033). HIV-1 infected women with low CD4 counts (less than 350 cells/μL) and those with viral load more than 1000 copies/mL were about twice as likely to have an spontaneous abortion [OR (IC 95%): 2.50 (1.085 - 5.760); p = 0.03] and [OR (95% CI): 2.16 (1.043 - 4.505); p = 0.04]. Conclusions: The results of this study show the need to improve the treatment of HIV-1 infected women in order to restore CD4 levels and make viral load of HIV-1 undetectable.

Increasing bacterial resistance to antimicrobial agents has become an issue of concern. A major problem of the treatment of infections caused by Enterobacteriaceae using antibiotics is the emergence of Extended-spectrum β-lactamases (ESBL)-producing Enterobacteriaceae. This study aims to determine the prevalence of ESBL-producing Enterobacteriaceae strains in Ouagadougou, Burkina Faso, and describe their resistance profile to other antibiotics commonly used in the infections treatment. 486 clinical strains of Enterobacteriaceae were obtained from patients attending three health centers in Ouagadougou (Burkina Faso) from November 2014 to October 2015. Biochemical identification was performed and antibiotics susceptibility test was performed using the disk diffusion method. Data was analyzed with the Excel and ANOVA one-way software GraphPad Prism version 5.01 software. Results revealed occurrence of Escherichia coli (60.9%, 194) predominated followed by Klebsiella spp. (22.4%, 109). Antibiotics susceptibility test revealed that 86.8% strains were resistant to amoxicillin, 81.3% to trimethoprim-sulfamethoxazole, 61.9% to ceftriaxone, 58.6% to cefotaxime and 58.4% to cefepime. It was observed that 99.8% were susceptible to imipenem while 16.6% were resistant to fosfomycin and 12.3% to amikacin. However, 38.5% (187/486) of the strains were ESBL-producing, 67.9% (127/187) of which came from Yalgado Ouedraogo University Hospital Center, 23.5% (44/187) from Charles De Gaulle Paediatric University Hospital Center and 8.6% (16/187) from Saint Camille Hospital. This study thus showed a high prevalence of Extended-Spectrum Β-Lactamases producing Enterobacteriaceae strains in Ouagadougou (38.5%). It underlined the need for routine detection and systematic reporting of ESBL strains in different health facilities in Burkina Faso, so that measures could be taken to prevent their spread and treatment failures. Key words: Enterobacteriaceae, Extended-Spectrum Beta-lactamases (ESBL), Burkina Faso.
