RESUMO

We sought to determine the prevalence of probable disseminated histoplasmosis among advanced HIV disease (AHD) patients in Nigeria. We conducted a cross-sectional study in 10 sites across 5 of 6 geopolitical zones in Nigeria. We identified patients with urinary samples containing CD4 cell counts <200 cells/mm3 or World Health Organization stage 3 or 4 disease who also had >2 clinical features of disseminated histoplasmosis, and we tested them for Histoplasma antigen using a Histoplasma enzyme immune assay. Of 988 participants we recruited, 76 (7.7%) were antigen-positive. The 76 Histoplasma antigen-positive participants had significantly lower (p = 0.03) CD4 counts; 9 (11.8%) were also co-infected with tuberculosis. Most antigen-positive participants (50/76; 65.8%; p = 0.015) had previously received antiretroviral treatment; 26/76 (34.2%) had not. Because histoplasmosis is often a hidden disease among AHD patients in Nigeria, Histoplasma antigen testing should be required in the AHD package of care.

RESUMO

Since its outbreak, COVID-19 disease has claimed over one hundred thousand lives in the United States, resulting to multiple and complex nation-wide challenges. In this study, we employ global and local regression models to assess the influence of socio-economic and health conditions on COVID-19 mortality in contiguous USA. For a start, stepwise and exploratory regression models were employed to isolate the main explanatory variables for COVID-19 mortality from the ensemble 33 socio-economic and health parameters between January 1st and 16th of September 2020. Preliminary results showed that only five out of the examined variables (case fatality rate, vulnerable population, poverty, percentage of adults that report no leisure-time physical activity, and percentage of the population with access to places for physical activity) can explain the variability of COVID-19 mortality across the Counties of contiguous USA within the study period. Consequently, we employ three global and two local regression algorithms to model the relationship between COVID-19 and the isolated socio-economic and health variables. The outcomes of the regression analyses show that the adopted models can explain 61%-81% of COVID-19 mortality across the contiguous USA within the study period. However, MGWR yielded the highest R2 (0.81) and lowest AICc values (4031), emphasizing that it is the most efficient among the adopted regression models. The computed average adjusted R2 values show that local regression models (mean adj. R2 = 0.80) outperformed the global regression models (mean adj. R2 = 0.64), indicating that the former is ideal for modeling spatial causal relationships. The GIS-based optimized cluster analyses results show that hotspots for COVID-19 mortality as well as socioeconomic variables are mostly delineated in the South, Mid-West and Northeast of contiguous USA. COVID-19 mortality exhibited positive and significant association with black race (0.51), minority (0.48) and poverty (0.34). Whereas, the percentage of persons that attended college was negatively associated with poverty (-0.51), obesity (-0.50) and diabetes (-0.45). Results show that education is crucial to improve socio-economic and health conditions of the Americans. We conclude that investing in people's standard of living would reduce the vulnerability of an entire population.

RESUMO

Two novel bacteria species designated Marseille-Q1000T and Marseille-Q0999T were isolated from urine samples of patients in Sokoto, Northwest-Nigeria. They were Gram-positive bacteria and belong to two different genera, Bhargavaea and Dietzia. The genome size and G + C content of Marseille-Q1000T and Marseille-Q0999T were 3.07 and 3.51 Mbp with 53.8 and 71.0 mol% G + C content, respectively. The strains exhibited unique phenotypic and genomic features that are substantially different from previously known bacterial species with standing in nomenclature. On the basis of the phenotypic, phylogenetic and genomic characteristics, strains Marseille-Q0999T (= CSURQ0999 = DSM 112394) and Marseille-Q1000T (= CSURQ1000 = DSM 112384) were proposed as the type strains of Bhargavaea massiliensis sp. nov., and Dietzia massiliensis sp. nov., respectively.

RESUMO

BACKGROUND: Infections with Staphylococcus aureus cause significant morbidity and mortality worldwide. Resistant strains of S. aureus to commonly used antibiotics are being increasingly encountered in clinical practice, necessitating the need to determine the resistance pattern in Nigeria. METHODS: Antibiotic susceptibility testing was performed on 360 S. aureus isolates from clinical specimen from seven hospitals across the six geo-political regions of Nigeria using Kirby Bauer disc diffusion technique, and E-test for vancomycin. Cefoxitin 30 µg disc was used to determine methicillin resistance, and D-test for inducible clindamycin resistance. RESULTS: Methicillin-resistant S. aureus was confirmed in 176 (48.9%) of the isolates, 346 (96%) for penicillin G and 311 (86.4%) for trimethoprim. 175 (99.4%) of the 176 resistant to methicillin were susceptible to vancomycin. Linezolid, tigecycline, chloramphenicol and clindamycin had susceptibilities of 341 (94.7%), 332 (92.2%), 298 (82.8%) and 290 (80.6%) respectively. Inducible clindamycin resistance was elucidated in 25 (29.1%) of the 86 isolates. Generally, MRSA isolates were more resistant than methicillin-sensitive S. aureus (MSSA) to all antibiotics tested. CONCLUSION: Staphylococcus aureus rates of resistance are high and call for urgent action such as antibiotic stewardship programmes and periodic surveillance to enhance clinical outcomes. While targeted therapy is preferred, options for empiric treatment include chloramphenicol, clindamycin, linezolid or vancomycin.

RESUMO

Background: In spite of its global notoriety and WHO alarm, Acinetobacter baumannii is still an understudied critical-priority pathobiont in Nigeria. We characterized its antimicrobial susceptibility profile and resistance genes during an outbreak. Materials and Methods: This cross-sectional study involved collection of patients' urine samples and swabs from unit staff's hands and ward environments for the identification of A. baumannii strains using standard morphologic and biochemical methods. The disk diffusion method was used to assess the antimicrobial susceptibility profile of the isolates with the production of extended-spectrum beta-lactamases (ESBLs) confirmed by the combined disk test screening method. Characterization of the resistance genes of the ESBL producers was carried out using polymerase chain reaction polymerase chain reaction technique. Results: A.total of eight (six clinical and two nonclinical) A. baumannii isolates were identified. The overall isolate susceptibility and resistance rates to all the antimicrobial agents was 56.3% (27/48) and 35.4% (17/48), respectively. Similarly, all (8/8; 100.00%) isolates were susceptible to meropenem and 75.0% (6/8) to ampicillin-sulbactam while 62.5% (5/8) were resistant to trimethoprim-sulfamethoxazole and 50.0% (4/8) to each of ciprofloxacin and ceftazidime. In addition, 37.5% (3/8) of the isolates were multidrug resistant (MDR) with nonclinical isolates exhibiting more antimicrobial resistance than their clinical counterparts (9/12%-75.0% vs. 8/36%-22.2%). Phenotypic detection and molecular characterization revealed three ESBL-producing isolates that each harbored blaSHV and blaTEM genes with blaCTX-M gene being absent. Conclusion: MDR strains of A. baumannii harboring blaSHV and blaTEM genes were recovered from clinical and environmental sources during the outbreak, which was contained with preventive measures recommended.


Résumé En dépit des alertes faites par l'organisation mondiale de la Santé (OMS), Acinetobacter baumannii demeure un pathobiont sous-étudié et très peu priorisé au Nigeria. Nous avons procedé à sa caractérisation phénotypique et génotypique en dressant son profil de sensibilité aux antimicrobiens et ainsi que les gènes de résistance impliqués au cours d'une épidémie. Matériel et méthodes: Cette étude transversale a consisté à collecter des échantillons d'urine de patients et des écouvillons des mains du personnel des soins et de l'environnement hospitalier. L'identification des souches d' A. baumannii était faite par des méthodes bactériologiques standard. le profil de sensibilité aux antimicrobiens des isolats a été faite par la méthode de diffusion de disque , les bêta-lactamases à spectre étendu (BLSE) étaient recherchée par la méthode de dépistage combinée de disque ainsi que leur caractérisation moléculaire par la mise en évidence des gènes de résistance BLSE à l'aide d'une PCR (réaction en chaîne par polymérase). Résultats: Au total, huit isolats d'A. baumannii (6 cliniques et 2 de l'environnement) ont été identifiés. Les taux globaux de sensibilité et de résistance des isolats à tous les agents antimicrobiens étaient respectivement de 56,3 % (27/48) et de 35,4 % (17/48). De même, tous les isolats (8/8 ; 100,00 %) étaient sensibles au méropénème et 75,0 % (6/8) à l'ampicilline-sulbactam, tandis que 62,5 % (5/8) étaient résistants au triméthoprime-sulfaméthoxazole et 50,0 % (4/8) à la ciprofloxacine et à la ceftazidime. En outre, 37,5 % (3/8) des isolats étaient multirésistants (MDR), les isolats non cliniques présentant une plus grande résistance aux antimicrobiens que leurs homologues cliniques (9/12 %-75,0 % contre 8/36 %-22,2 %). La détection phénotypique et la caractérisation moléculaire ont révélé trois isolats producteurs de BLSE qui hébergeaient chacun les gènes blaSHV et blaTEM, le gène blaCTX-M étant absent. Conclusion: Des souches multirésistantes d'A. baumannii portant les gènes blaSHV et blaTEM ont été identifiées sur des prélevements cliniques et environnementaux au cours de l'épidémie, qui a été gerée grâce aux mesures préventives recommandées.

RESUMO

The incidence of disseminated gonococcal infection (DGI) is rising in some parts of the world, but there is paucity of data on its true incidence from sub-Saharan Africa. DGI has varied manifestations in different population group. We report a case of a 30-year-old sexually active woman presenting with hemorrhagic symptoms 2 weeks after a surgery on account of diagnosis of uterine fibroid made at a peripheral hospital. A multidrug-resistant Neisseria gonorrhoeae was isolated from the wound on her surgical site and blood sample. She was managed with intravenous meropenem, pressure dressing, and blood products, with the patient making a full recovery after a week. This case is presented because it is a rare one. Moreover, there is the need to revive the awareness of clinicians on the existence of multidrug-resistant gonococcus in our environment. We herein report a case of DGI from Nigeria.

RESUMO

Background: Rheumatic heart disease (RHD) is the only preventable cardiovascular disease that still causes significant morbidity and mortality in low- and middle-income countries like Nigeria where it is classified as a neglected disease. The inciting agent causes pharyngitis often not properly treated. Aim and Objectives: To study the knowledge and preventive practices of RHD amongst primary healthcare workers who are in contact with larger ratio of populace in order to recommend appropriate interventions. Methodology: A cross-sectional study conducted among health workers in primary health centres in Sokoto metropolis. Multi-stage sampling technique was used to recruit the study participants. A structured questionnaire and focus group discussion guide was used to collect the information. Data was analysed using IBM SPSS version 25. Results: Majority (109/182; 59.8%) had RHD inadequate knowledge of causes, risk factors and treatment of pharyngitis which predisposes to RHD. Only 49 (26.9%) of the respondents knew the name of the causative agent. The knowledge gap was related to length of training and attendance at a training (ꭓ2 = 8.38; P=0.015 & ꭓ2 = 7.92; P=0.004). Majority of the respondents with 168 out of 182 (92.3%) had positive attitude. Practice grading was adequate in only less than half of the respondents (88/182; 48.4%). Male gender and negative attitude were predictors of adequacy of preventive practices (aOR= 0.49; 95% C.I =0.267-0.929; P=0.03 & aOR= 3.87; 95% C.I =1.027-14.586; P=0.046). Conclusion: The health workers had inadequate knowledge and poor practice on prevention of rheumatic heart disease. It is necessary to upscale information available to them by medical specialists and upgrade their curriculum.


Résumé Arrière-plan: La cardiopathie rhumatismale (RHD) est la seule maladie cardiovasculaire évitable qui cause encore une morbidité et une mortalité importantes dans les pays à revenu faible et intermédiaire comme le Nigeria où elle est classée comme une maladie négligée. L'agent incitant provoque une pharyngite souvent mal traitée. But et objectifs: Étudier les connaissances et les pratiques préventives de RHD parmi les agents de santé primaires qui sont en contact avec une plus grande proportion de la population afin de recommander des interventions appropriées. Méthodologie: Une étude transversale menée auprès des agents de santé des centres de santé primaires de la métropole de Sokoto. La technique d'échantillonnage à plusieurs degrés a été utilisée pour recruter les participants à l'étude. Un questionnaire structuré et un guide de discussion de groupe ont été utilisés pour recueillir les informations. Les données ont été analysées à l'aide d'IBM SPSS version 25. Résultats: La majorité (109/182 ; 59,8 %) avaient une connaissance inadéquate des causes, des facteurs de risque et du traitement de la pharyngite qui prédispose à la RHD. Seuls 49 (26,9%) des répondants connaissaient le nom de l'agent causal. Le déficit de connaissances était lié à la durée de la formation et à la participation à une formation (ꭓ2 = 8,38 ; P=0,015 & ꭓ2 = 7,92 ; P=0,004). La majorité des répondants avec 168 sur 182 (92,3%) avaient une attitude positive. La notation de la pratique n'était adéquate que pour moins de la moitié des répondants (88/182 ; 48,4 %). Le sexe masculin et l'attitude négative étaient des prédicteurs de l'adéquation des pratiques préventives (aOR = 0,49 ; IC à 95 % = 0,267-0,929 ; P = 0,03 et aOR = 3,87 ; IC à 95 % = 1,027-14,586 ; P = 0,046). Conclusion: Les agents de santé avaient des connaissances insuffisantes et de mauvaises pratiques en matière de prévention des cardiopathies rhumatismales. Il est nécessaire de valoriser les informations mises à leur disposition par les médecins spécialistes et d'améliorer leur cursus.

RESUMO

As of 2018, cryptococcal antigen (CrAg) screening in patients with advanced human immunodeficiency virus (HIV) disease (AHD) was not routinely implemented in Nigeria despite being recommended in the national HIV treatment guidelines. Our aim was to determine the prevalence and risk factors for asymptomatic cryptococcal antigenemia in adult people living with HIV (PLHIV) in Nigeria to advocate for the implementation of routine CrAg screening. A descriptive cross-sectional study and CrAg screening of consecutive adult PLHIV with CD4 counts ≤200 cells/µL was conducted from April 2018 to April 2019 at HIV clinics in eleven tertiary hospitals spread across Nigeria's six geopolitical regions. Prevalence of asymptomatic cryptococcal antigenemia was estimated by facility and geopolitical zone. Logistic regression was conducted to identify risk factors for cryptococcal antigenemia. In total, 1,114 patients with AHD were screened. The overall prevalence of asymptomatic cryptococcal antigenemia was 3.9% with wide variation across facilities (range: 0/75 [0%]- 15/122 [12.3%]) and geopolitical zones (range: 0/75 [0%]-19/279 [6.8%]). Prevalence of antigenemia was highest in the South-West (19/279 [6.8%]) and lowest in the North-East (0/75 [0%]). Prevalence was 5.2% (26/512) and 3.2% (18/561) in patients with CD4<100 and CD4 of 101-200, respectively. Of all patients with antigenemia, 50% were on antiretroviral therapy (ART) at the time of having a positive CrAg test. In adjusted analysis, cryptococcal antigenemia was significantly less in patients on ART and patients who had completed any formal education. The survey showed a high overall burden of cryptococcal antigenemia in Nigeria, with variable prevalence across geopolitical regions. We provided valuable evidence for implementing routine CrAg screening of AHD patients in Nigeria which has commenced in selected centres.

RESUMO

Nigeria is estimated to have the largest number of children worldwide, living with chronic hepatitis B virus (HBV) infection, the leading cause of liver cancer. Up to 90% of children infected at birth develop chronic HBV infection. A birth dose of the hepatitis B vaccine (HepB-BD) followed by at least two additional vaccine doses is recommended for prevention. This study assessed barriers and facilitators of HepB-BD administration and uptake, using structured interviews with healthcare providers and pregnant women in Adamawa and Enugu States, Nigeria. The Consolidated Framework for Implementation Sciences Research (CFIR) guided data collection and analysis. We interviewed 87 key informants (40 healthcare providers and 47 pregnant women) and created a codebook for data analysis. Codes were developed by reviewing the literature and reading a subsample of queries line-by-line. The overarching themes identified as barriers among healthcare providers were: the lack of hepatitis B knowledge, limited availability of HepB-BD to vaccination days only, misconceptions about HepB-BD vaccination, challenges in health facility staffing capacity, costs associated with vaccine transportation, and concerns related to vaccine wastage. Facilitators of timely HepB-BD vaccination included: vaccine availability, storage, and hospital births occurring during immunization days. Overarching themes identified as barriers among pregnant women were lack of hepatitis B knowledge, limited understanding of HepB-BD importance, and limited access to vaccines for births occurring outside of a health facility. Facilitators were high vaccine acceptance and willingness for their infants to receive HepB-BD if recommended by providers. Findings indicate the need for enhanced HepB-BD vaccination training for HCWs, educating pregnant women on HBV and the importance of timely HepB-BD, updating policies to enable HepB-BD administration within 24 hours of birth, expanding HepB-BD availability in public and private hospital maternity wards for all facility births, and outreach activities to reach home births.

RESUMO

Empedobacter falsenii is an emerging opportunistic pathogen that has been occasionally implicated in various human infections. In this study, we described the genomic features of a multidrug resistant E. falsenii Q1655 obtained from a patient attending a public hospital in Sokoto, northwest Nigeria. The isolate, E. falsenii Q1655, was isolated from the stool sample of a patient in Sokoto, Nigeria. The identity of the isolate was confirmed by MALDITOF-MS. The disc diffusion test and modified Carba-NP test were used for phenotypic antibiotic susceptibility test and carbapenemase enzyme production test, respectively. The whole genome of the strain was sequenced using the Illumina MiSeq technique. Resistome analysis was done by annotation of the WGS against the ARG-ANNOT database. The isolate was resistant to all ß-lactam antibiotics with the exception of cefepime. The MICs of imipenem and ertapenem as determined by E-test were 12 µg/ml and 2 µg/ml, respectively. Modified Carba NP test showed that the strain was carbapenemase producing. Resistome analysis revealed the presence of a novel metallo-ß-lactamase, a chromosomal blaEBR-4, which exhibited 94.92% and 97.02% nucleotide and protein sequence identities respectively with blaEBR-3 gene of E. falsenii 174,820. Seven and eight amino-acid substitutions were observed with the blaEBR-1 and blaEBR-2, respectively. We reported the first isolation and genomic description of an extensively drug resistant isolate of Empedobacter falsenii in Nigeria. This report broadens our knowledge of carbapenem resistance in E. falsenii and it will serve as a useful guide in the development of antibiotic use policy.

RESUMO

INTRODUCTION: Emphysematous pyelonephritis is a life-threatening necrotising bacterial infection of the kidneys. It is rare among children and can be fatal if not promptly identified and treated. CASE PRESENTATION: A 7-month-old male infant presented to the Emergency Paediatric Unit of Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria, on 12 November 2019 with a 5-day history of fever and vomiting, and a 3-day history of a progressively enlarging, left-side abdominal mass. There was associated excessive crying on micturition, refusal to feed and weight loss. He looked ill and was in respiratory distress, irritable, febrile (38.8 °C), moderately dehydrated and pale. His weight and length were 5.5 kg and 64 cm. He had a tender, firm and ballotable abdominal mass on the left flank measuring 8 cm × 10 cm. His pulse rate was 140 beats/min, blood pressure 60/40 millimetres of mercury and respiratory rate was 65 cycles/min. He had widespread coarse crepitations and normal heart sounds on chest auscultation. MANAGEMENT AND OUTCOME: An initial diagnosis of sepsis was made. Other considerations were nephroblastoma and neuroblastoma. Ceftriaxone and blood transfusion were commenced with subsequent administration of intravenous fluids. Further radiologic investigations revealed emphysematous pyelonephritis. The patient had percutaneous drainage and extended spectrum ß-lactamase-producing Escherichia coli (sensitive to meropenem) which was isolated from the aspirate culture after 48 h of incubation. Meropenem could not be commenced because of non-availability and high cost. The patient subsequently deteriorated and died from septic shock. CONCLUSION: Emphysematous pyelonephritis has a fulminant course when not diagnosed promptly and treated adequately.

RESUMO

INTRODUCTION: The COVID-19 pandemic continues to overwhelm health systems across the globe. We aimed to assess the readiness of hospitals in Nigeria to respond to the COVID-19 outbreak. METHOD: Between April and October 2020, hospital representatives completed a modified World Health Organisation (WHO) COVID-19 hospital readiness checklist consisting of 13 components and 124 indicators. Readiness scores were classified as adequate (score ≥80%), moderate (score 50-79.9%) and not ready (score <50%). RESULTS: Among 20 (17 tertiary and three secondary) hospitals from all six geopolitical zones of Nigeria, readiness score ranged from 28.2% to 88.7% (median 68.4%), and only three (15%) hospitals had adequate readiness. There was a median of 15 isolation beds, four ICU beds and four ventilators per hospital, but over 45% of hospitals established isolation facilities and procured ventilators after the onset of COVID-19. Of the 13 readiness components, the lowest readiness scores were reported for surge capacity (61.1%), human resources (59.1%), staff welfare (50%) and availability of critical items (47.7%). CONCLUSION: Most hospitals in Nigeria were not adequately prepared to respond to the COVID-19 outbreak. Current efforts to strengthen hospital preparedness should prioritize challenges related to surge capacity, critical care for COVID-19 patients, and staff welfare and protection.

RESUMO

Carbapenemase-producing Alcaligenes species has been described in only few studies, with none so far from the African continent. Here, we report the whole genome sequence of Peanalcaligenes suwonensis bearing blaVIM-5 metallo-ß-lactamase and first detection of carbapenemase producing Alcaligenes faecalis isolated from patients attending tertiary healthcare facilities in Nigeria. The isolates were identified by MALDI-TOF Mass Spectrometry. Antibiotic susceptibility assay, modified Carba NP test and genomic investigation revealed that two isolates of Alcaligenes faecalis and an isolate of Paenalcaligenes suwonensis harboured blaVIM-5 gene. The genome sequence analysis of the P. suwonensis 191B isolate, responsible for acute gastroenteritis, reveal the presence of 18 antibiotic resistance genes coding for resistance to five different classes of antibiotics. Three of the genes (blaOXA-368, blaCARB-4 and blaVIM-5) codes for resistance to ß-lactam antibiotics. To our best knowledge, we describe here the first genome sequence of P. suwonensis species and the first detection of class B carbapenemase blaVIM-5 in a clinical isolate of P. suwonensis species and Alcaligenes faecalis in Nigeria. The finding of this study is of concern, as lateral dissemination of the genes into clinically important Gram-negative pathogens is highly likely.

RESUMO

INTRODUCTION: There have been numerous reported opportunistic infections among HIV/AIDS patients. However, coexistence of Kaposi sarcoma and Molluscum contagiosum on the same site is a rare finding. CASE PRESENTATION: A 37-year-old man poorly adherent to antiretroviral therapy presented with Molluscum contagiosum and Kaposi sarcoma occurring simultaneously on numerous skin lesions around mid-2017 at Usmanu Danfodiyo University Teaching Hospital, Sokoto State, Nigeria. MANAGEMENT AND OUTCOME: The patient was counselled and re-initiated on a second-line highly active antiretroviral therapy regimen. The patient's lesions resolved three months later. DISCUSSION: The case is presented to improve the index of suspicion among clinicians and pathologists on such rare occurrences.

RESUMO

INTRODUCTION: measles is a vaccine preventable, highly transmissible viral infection that affects mostly children under five years. We reviewed surveillance data on measles from Nigeria over a five-year period to highlights its burden and make recommendations for improvements. METHODS: we conducted a secondary data analysis of measles specific Integrated Disease Surveillance and Response (IDSR) records of all states in Nigeria over a five-year period. RESULTS: a total of 131,732 cases were recorded between January 2012 and September 2016. Most cases 57,892 (43.95%) were recorded in 2013 while the least 11,061 (8.4%) were recorded in 2012. A total of 817 deaths were recorded, with a case fatality rate (CFR) of 0.62%. The highest CFR (1.43%) was recorded in 2012 while the least CFR (0.44%) was recorded in 2016. Only 8,916 (6.7%) cases were confirmed by laboratory tests. The trend of measles cases followed the same pattern throughout the years under review, with cases peaking at March, then gradually reducing to lowest level at June, which was maintained throughout the rest of the year. States in northern region of Nigeria recorded the highest attack rate (Yobe: 480.29 cases per 100,000 population, Sokoto: 284.63 cases per 100,000 population and Katsina: 246.07 cases per 100,000 population) compared to States in the southern region (Rivers: 11.72 cases per 100,000 population and Akwa Ibom: 13.59 cases per 100,000 population). Conversely, States in the southern region recorded the highest CFR (Ebonyi: 13.43% and Rivers: 3.27%). CONCLUSION: measles infection remains a burden especially in the northern region of Nigeria. Although measles fatalities declined over the years, laboratory confirmation was sub-optimal. We recommended improvement on routine immunization and strengthening of regional laboratories diagnostic capacities, for successful eradication of measles from Nigeria.

RESUMO

BACKGROUND: The World Health Assembly adopted the Global Action Plan on Antimicrobial Resistance, which includes improving the knowledge base through surveillance and research. Noteworthily, the World Health Organization has advocated a Global Antimicrobial Resistance Surveillance System to address the plan's surveillance objective, with most African countries enrolling in or after 2017. AIM: The aim of this article was to review prior data on antimicrobial resistance of Vibrio cholerae from sub-Saharan Africa with a view for future control and intervention strategies. METHODS: We used the Preferred Reporting Items for Systematic Review and Meta-Analysis (or 'PRISMA') guidelines to search the PubMed and African Journals Online databases, as well as additional articles provided by the Nigeria Centre for Disease Control, for articles reporting on the antibiotic susceptibility of V. cholerae between January 2000 and December 2017. RESULTS: We identified 340 publications, of which only 25 (reporting from 16 countries within the sub-Saharan African region) were eligible. The majority (20; 80.0%) of the cholera toxigenic V. cholerae isolates were of the serogroup O1 of the El Tor biotype with Ogawa and Inaba serotypes predominating. Resistance was predominantly documented to trimethoprim-sulphamethoxazole (50% of the studies), ampicillin (43.3% of the studies), chloramphenicol (43.3% of the studies) and streptomycin (30% of the studies). Resistance mechanisms were reported in 40% of the studies. CONCLUSION: Our results demonstrate a documented antimicrobial resistance of V. cholerae to multiple antibiotic classes, including cell wall active agents and antimetabolites with evidence of phenotypic/genotypic resistance to fluoroquinolones.

RESUMO

INTRODUCTION: Ecthyma gangrenosum (EG) is a cutaneous lesion commonly caused by Pseudomonas aeruginosa that involves mainly the lower limbs and gluteal region, seen more in immunosuppressed patients with neutropenia. Cancrum oris (Noma) is a gangrenous necrosis of the face that begins as a gingival ulcer and progresses rapidly to destroy contiguous tissues in malnourished children. CASE PRESENTATION: This article reports a case of facial EG which was similar to Noma in a malnourished child: a 16-month old girl with fever, cough, weight loss, watery stool and swelling on right cheek. She was febrile, pale, wasted with bilateral pitting pedal oedema. She had a solitary circumscribed round necrotic lesion, with surrounding hyperaemia on the right malar area which extended to destroy the right ala nasi. No intra-oral rashes but she had left ear discharge. She received blood transfusion, antibiotics, antiseptic wound care and nutritional rehabilitation. MANAGEMENT AND OUTCOME: Swabs of the lesion and ear discharge both revealed Gram-negative bacilli and culture yielded P. aeruginosa. Retroviral, Mantoux and Gene Xpert tests were negative. She had moderate anaemia, normal white blood cell count, and neutropaenia. Parenteral ceftriazone was changed to ciprofloxacin based on sensitivity results and lack of clinical response. The wound healed with residual scarring and partial destruction of right ala nasi. DISCUSSION: Although this patient had facial necrosis to suggest Noma, she did not have initial oral involvement, and clinical features such as Pseudomonas sepsis and neutropaenia suggested EG. Facial necrosis in malnourished children may be due to EG.

RESUMO

INTRODUCTION: Students in the universities mostly live independently from their parents or guardians, some of them for the first time. This gives them freedom and opportunity for high risk behavior such as unplanned and unprotected sex. The results of such sexual experimentation may include unplanned and or unwanted pregnancies that may lead to unsafe abortions and sexually transmitted infections (STIs) including HIV/AIDS. Contraception has the potential to prevent unwanted pregnancies, abortion, and STIs. This study aimed at assessing the general knowledge on contraceptives, sexual practices, and level of utilization of contraceptives devices among unmarried students of the Bayero University Kano. METHODS: We did an institutional based cross-sectional descriptive study. We administered a pretested, self-administered, structured questionnaire to randomly selected unmarried undergraduate students of the institution. We analyzed data using Microsoft Excel 2016 and Epi-info7. RESULTS: A total of 300 students were interviewed. The median age for respondents was 23 years with an age range of 16-25 years. Male respondents made up 61.3% (184) while the females made up the remaining 38.7% (116). Also, 158(47.33%) of respondents lived outside the school campus, while 158(52.67%) lived in the school hostels. Knowledge on contraception was 87.7% among respondents with internet (91%) and media (89.3%) as the commonest sources of knowledge. Proportion of sexually active students was 10.67%, while prevalence of contraceptive utilization among sexually active students was 15.63%. About 8(25%) had their sexual debut at < 16years of age, 22(68.75%) at ages between 16-20years, and 4(12.5%) above 20years of age. All sexually active respondents practice vaginal sex. Most sexual debuts were planned (44.75 %) and with friends (86.4%), and they occurred between the ages of 16-20years age group in 70.3% of respondents. CONCLUSION: Even though knowledge on contraceptive used was high among the respondents, utilization of contraceptives among sexually active students was low, thus creating a window for possible unintended and unwanted pregnancies among these group of students.

RESUMO

INTRODUCTION: Resistance to antimicrobials has become a serious global health concern complicating treatment strategies and increasing health-care costs. The extended-spectrum beta-lactamase producing bacteria stand out as bacteria of great epidemic concern among Gram negative bacilli. Control and appropriate interventions for antimicrobial resistance depend on effective surveillance and knowledge of the patterns and determinants of resistance. AIM: The present study was undertaken to detect and characterize ESBLs in Escherichia coli and Klebsiella Species from University of Maiduguri Teaching Hospital, Maiduguri, North-Eastern Nigeria. MATERIALS AND METHODS: Confirmed variants of Escherichia coli and Klebsiella Species isolated from 439 patients that were admitted in various units of University of Maiduguri Teaching Hospital (UMTH) were screened for ESBL using CLSI breakpoints. Suspected ESBLs producers were subjected to confirmation using double disk synergy method. Detection of ESBL genes was further done by multiplex PCR. RESULTS: Out of the 439 isolates screened; the result shows 147 (33.5%) were ESBL producers but only 121(23.6%) were confirmed by the double disk synergy method. The prevalence of ESBL amongst the organisms were; 41/172 (23.8%) for Escherichia coli and 80/267/(30.0%) for Klebsiella Species. Based on PCR analysis, the various percentage genotypes of the ESBL producers were 44 (36.4%) for SHV gene followed by 38(31.4%) for TEM gene and the lowest of 33(27.3%) for CTX-M gene. CONCLUSION: ESBLs are prevalent among Species of Escherichia coli and Klebsiella Species in Maiduguri, Borno State, not only are there TEM and SHV but also CTX-M types. Antibiotic stewardship program to maximise use of available antibiotics is underscored as well as coordinated national efforts in combating resistance.
