Determinants of Antimicrobial Use for Covid-19 Related Symptoms among Nigerians.

BACKGROUND: Antimicrobial use plays a key role in development and spread of antimicrobial resistance. Following the global coronavirus disease 2019 (COVID-19) pandemic and the report of the first confirmed case in Nigeria, several states embarked on either a full or partial lockdown as a measure to prevent or curtail the spread of the virus with its attendant challenges. This survey was designed to provide a snapshot of public antimicrobial use and common perception related to antimicrobial use for COVID-19 related symptoms among Nigerian populace. METHODS: We developed and tested a 29-question electronic questionnaire with Google forms asking respondents about their antimicrobial use and perceptions regarding appropriate antimicrobial use for real or perceived symptoms during the outbreak period. Respondents aged 18 years and above were recruited through crowd sourcing and they received the link to the survey tool through emails and social media including WhatsApp, Twitter, Facebook, LinkedIn, and Instagram. All data analysis was performed using SPSS version 26.0. RESULTS: A total of 410 responses were received from the six geopolitical zones in Nigeria comprising 200 (48.8%) females and 210 (51.2%) males. Majority (62.9%) of the respondents had taken antimicrobials in the 3 months period preceding the survey, while less than half (46.8%) received prescription for it. Previous intake of antimicrobial for similar illness was a predictor of antimicrobial intake (OR: 0.55, 95%CI: 0.30-1.01). The most consumed antimicrobial was antimalarial drugs, specifically Artemisinin-based combination therapy (43.4%), followed by antibiotics [Ciprofloxacin (20.2%)]. CONCLUSION: There was high levels of antimicrobial use for COVID-19 related symptoms by the Nigerian public. This is likely to escalate the already high prevalence of antimicrobial use previously reported and may further fuel the emergence of antimicrobial resistance.

CONTEXTE: L'utilisation d'antimicrobiens joue un rôle clé dans le développement et la propagation de la résistance aux antimicrobiens. À la suite de la pandémie mondiale de coronavirus 2019 (COVID-19) et du rapport du premier cas confirmé au Nigéria, plusieurs États se sont engagés dans un verrouillage complet ou partiel en tant que mesure pour prévenir ou freiner la propagation du virus avec ses défis associés. Cette enquête a été conçue pour fournir un aperçu de l'utilisation publique des antimicrobiens et de la perception commune liée à l'utilisation des antimicrobiens pour les symptômes liés au COVID-19 parmi la population nigériane. MÉTHODES: Nous avons développé et testé un questionnaire électronique de 29 questions avec des formulaires Google interrogeant les répondants sur leur utilisation d'antimicrobiens et leurs perceptions concernant l'utilisation appropriée d'antimicrobiens pour les symptômes réels ou perçus pendant la période d'épidémie. Les répondants âgés de 18 ans et plus ont été recrutés via le crowdsourcing et ils ont reçu le lien vers l'outil d'enquête via des e-mails et des médias sociaux, notamment WhatsApp, Twitter, Facebook, LinkedIn et Instagram. Toutes les analyses de données ont été effectuées à l'aide de la version 26.0 de SPSS. RÉSULTATS: Un total de 410 réponses ont été reçues des six zones géopolitiques du Nigéria comprenant 200 (48,8%) femmes et 210 (51,2%) hommes. La majorité (62,9%) des répondants avaient pris des antimicrobiens au cours des 3 mois précédant l'enquête, tandis que moins de la moitié (46,8%) en avaient reçu une prescription. La prise antérieure d'antimicrobiens pour une maladie similaire était un prédicteur de l'ingestion d'antimicrobiens (OR: 0,55, IC à 95%: 0,30-1,01). L'antimicrobien le plus consommé était les antipaludiques, en particulier les associations thérapeutiques à base d'artémisinine (43,4%), suivis des antibiotiques [Ciprofloxacine (20,2%)]. CONCLUSION: Il y avait des niveaux élevés d'utilisation d'antimicrobiens pour les symptômes liés au COVID-19 par le public nigérian. Cela est susceptible d'augmenter la prévalence déjà élevée de l'utilisation d'antimicrobiens rapportée précédemment et peut encore alimenter l'émergence de la résistance aux antimicrobiens.

Care-seeking behavioural patterns, awareness and diagnostic processes in patients with smear- and culture-positive pulmonary tuberculosis in Lagos, Nigeria.

This study was carried out in 2 chest referral clinics in Lagos, Nigeria, between February 2000 and May 2001 to assess the effects of knowledge, attitude, and practice of 168 newly diagnosed tuberculosis (TB) patients on their care-seeking behaviour. At the onset of symptoms patients sought treatment from one or more of the local private orthodox and traditional health providers, and patent medicine dealers before presenting at a chest clinic. There was a correlation between the level of knowledge and awareness of TB with time of presentation at the chest clinic. Of the 32 patients who presented and were diagnosed at the chest clinics within 4 weeks of onset of symptoms, 50% had knowledge of the aetiological agent of the disease and 60% had some idea of the mode of transmission. Of the 105 patients who presented and were diagnosed 12 weeks after the onset of symptoms, 97% had no knowledge of the aetiological agent and 95% had no idea of the mode of transmission. Overall there was a low level of knowledge and awareness of the disease as well as an apparently high level of improper health care-seeking behaviour amongst the patients studied which probably contributed significantly to the delay in early and accurate diagnosis of most of the cases. These findings indicate an urgent need to educate communities and care providers on the cause and mode of transmission of TB, and the need to attend designated health facilities for early diagnosis and proper treatment.

Fluconazole resistant opportunistic oro-pharyngeal Candida and non-Candida yeast-like isolates from HIV infected patients attending ARV clinics in Lagos, Nigeria.

BACKGROUND: Oro-Pharyngeal Candidiasis (OPC) continues to be considered the most common opportunistic fungal disease in HIV/AIDS patients globally. Azole antifungal agent has become important in the treatment of mucosal candidiasis in HIV patients. Presently, antifungal drug resistance is fast becoming a major problem particularly with the immune depleted population. OBJECTIVES: This study was designed to investigate the: existence of OPC, species distribution fluconazole susceptibility profile of yeast cells isolated from oral specimens of HIV/AIDS patients from Lagos Nigeria, between Oct. 2004 and June, 2005. METHODOLOGY: The venous blood samples were screened for HIV antibodies using the Cappillus HIV I and II test kit (Trinity Biotech Plc UK), and Genie II HIV I and II EIA kit (Bio-Rad France). The positive results were subsequently confirmed at the laboratory attached to each of the clinics, using the Nigerian Federal Ministry of Health approved algorithm. The samples from 213 (108 females and 105 males) HIV positive patients were plated onto SD agar. The isolates were identified by morphotyping, microscopy and speciated using germ tube test and battery of biochemical sugar fermentation and assimilation tests. Fluconazole agar diffusion susceptibility testing was carried out on each isolates. RESULTS: Seventy-four (34.7%) isolates were recovered including one person with double isolates. Only 70 (94.6%) of the isolates could be adequately speciated. Candida albicans 30 (40.5%) was the most frequently isolated species, the rest were non-albicans species, with the frequency of C. tropicalis > C. Krusei > C. glabrata and C. neoformans for species for species having up to 4 isolates. Four (30.8%) out of 13 isolates of C. tropicalis showed germ tube formation. While one C. albicans was germ-tube negative. Out of the 74 isolates tested for fluconazole sensitivity, 58 (78.4%) were sensitive, MIC d'' 8 microg/ml, 9 (12.1%) were susceptible Dose Dependent (SDD), MIC 16-32 microg/ml and 7 (9.5%) were resistant, MICs e'' 64 microg/ml. Among the C. albicans isolates, 26 (86.7%) were sensitive to fluconazole. The rank of susceptibility was C. albicans > C. tropicalis > C. Krusei for the most prevalent species. CONCLUSION: We conclude that fluconazole resistant strains of oro-pharyngeal yeast-like cells exist in about 9.5% of HIV/AIDS patients with the above stated species distribution. We therefore, highlight the need for routine antifungal susceptibility testing on HIV patients with cases of initial or repeat episodes of OPC.
