Background: The present study determined the incidence of rifampicin resistance M. tuberculosis among outpatients at the General Hospital Yauri, Kebbi State, Nigeria. Materials and Methods: The study is a cross-sectional study conducted from February 2018 to October 2019. Sociodemographic data were collected from hospital registration books. Rifampicin resistance M. tuberculosis was detected using GeneXpert Model GX-IV following manufacturers' instruction. Descriptive statistics and logistic regression were computed using SPSS version 20. The results were presented as odds ratios with associated 95% confidence intervals, and P-value at 0.05. Result: Of the 837 samples, 65.8% (551/837) were males, and 34.2% (286/837) females, 11.4% (95/837) HIV-seropositive. M. tuberculosis was detected in 15.5% (130/837), of which 116/130 (89.23%) were males and 14/130 (10.77%) females. M. tuberculosis¬-HIV coinfection was detected in 9.47% (9/95) of HIV positive. Rifampicin resistance was observed in 1.3% (11/837), 7.7% (10/130) in M. tuberculosis patients and 1.05% (1/94) in HIV seropositive. In logistic regression, the odds ratio for having a rifampicin-resistant M. tuberculosis was 0.49 (0.15-1.54) for > 30 years; taking <30 years as the reference value, 1.02 (1.00-1.03) for male; taking female as the reference value, and 0.78 (0.09-6.15) for HIV positive, taking negative as the reference value. Conclusion: This study reported the current incidence rate of rifampicin-resistant M. tuberculosis at the General Hospital Yelwa Yauri, Kebbi State, Nigeria, among presumptive TB patients. Patients diagnosed with rifampicin-resistant M. tuberculosis were predominantly male adults. Thus, frequent screening is vital for surveillance and reduces the risk of transmission and spread of M. tuberculosis infections.
Efforts are ongoing by researchers globally to develop new drugs or repurpose existing ones for treating COVID-19. Thus, this led to the use of oseltamivir, an antiviral drug used for treating influenza A and B viruses, as a trial drug for COVID-19. However, available evidence from clinical studies has shown conflicting results on the effectiveness of oseltamivir in COVID-19 treatment. Therefore, this systematic review and meta-analysis was performed to assess the clinical safety and efficacy of oseltamivir for treating COVID-19. The study was conducted according to the PRISMA guidelines, and the priori protocol was registered in PROSPERO (CRD42021270821). Five databases were searched, the identified records were screened, and followed by the extraction of relevant data. Eight observational studies from four Asian countries were included. A random-effects model was used to pool odds ratios (ORs), mean differences (MD), and their 95% confidence intervals (CI) for the study analysis. Survival was not significantly different between all categories of oseltamivir and the comparison groups analysed. The duration of hospitalisation was significantly shorter in the oseltamivir group following sensitivity analysis (MD -5.95, 95% CI -9.91—-1.99 p = 0.003, heterogeneity I2 0%, p = 0.37). The virological, laboratory and radiological response rates were all not in favour of oseltamivir. However, the electrocardiographic safety parameters were found to be better in the oseltamivir group. However, more studies are needed to establish robust evidence on the effectiveness or otherwise of oseltamivir usage for treating COVID-19.
The aim of this research was to determine the impact of biofilms on water distribution system of FederalUniversity Birnin Kebbi. Samples were collected from different water distribution pipelines in the University.Total heterotrophic count was carried out to determine the microbial load and Most Probable Method (MPN)was used to detect the presence of fecal coliforms in the water. Total heterotrophic bacterial count rangedbetween 1.6×103 to 3.9×103 cfu/ml. Escherichia Coli showed the highest frequency (25%) of occurrence, whilethe least frequency of occurrence (5%) was recorded for Klebsiella spp and Enterobacter spp respectively. Theisolates identified were Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella spp,Enterobacteria Spp, Salmonella Spp and Bacillus Spp. Presence of these isolates is of significant concern andmay cause some water borne diseases like diarrhea, dysentery etc. It is therefore recommended that water boardtreatment plant should use disinfectant chemicals like chlorine and perform regular proactive preventivemaintenance, microbial monitoring and infrastructure replacement and repair so as to reduce the occurrence ofbiofilms in the Water Distribution system.
Nosocomial or healthcare-associated infection (HCAI) is an infection acquired during receiving health care that was not present during admission. The research aimed to determine the antibiotic susceptibility pattern of gram-positive bacteria isolated from Primary Health Centers in Jega Town. A total of fifty (50) swab samples were collected from 10 different health centers and analyzed using the streak plate technique. Pure bacterial isolates were maintained and characterized using biochemical tests; their percentage of occurrence show; Staphylococcus aureus 18 (43.9%), Enterococcus feacalis 8 (19.5%), Streptococcus spp 8 (19.5%), Bacillus cereus 4 (9.8%), and Staphylococcus epidermidis 3 (7.3%). McFarland standard solution was prepared and used to control inoculants, after which the antibiotic susceptibility pattern of the isolates was determined using the disc diffusion method. Staphylococcus epidermidis was resistant to Gentamycin, and other isolates were multi-drug resistant. In light of this research, there is a need for thorough disinfection and conscientious contact control procedures to minimize the spread of these pathogens in health centers where interaction between patients, HCWs, and caregivers is widespread and frequent.
Background In Nigeria, effective case management and evaluation of pulmonary tuberculosis treatment outcomes are an integral part of controlling the spread of infectious diseases. The study reviewed the treatment outcomes of pulmonary tuberculosis and the factors associated with rates of successful and unsuccessful treatment outcomes in the 21 referral hospitals in Kebbi State, Nigeria. Methods Documented records of pulmonary tuberculosis patients from January 2018 to December 2021 in 21 Local Area Councils in Kebbi State, Northern Nigeria were reviewed. A structured questionnaire collated the socio-demographic and clinical data from the documented records. Descriptive statistics were used to compute and analyse the outcomes of successful and unsuccessful treatment. Logistic regression models were used to determine the association of socio-demographic and clinical data with the unsuccessful treatment outcomes. Results The study reviewed data from 6114 records of TB patients. 1161 (18.9%) started treatment, 963 (82.9%) were males and 198 (17.1%) were females. Of the 1161 patients, 985 (18.2%) had documented treatment outcomes. 932 of 985 (95.1%) had a pulmonary infection. 64 (5.8%) patients with documented treatment outcomes were HIV seropositive. 903 (91.7%) were successfully treated, and 82 (8.3%) failed. Of the patients with failed treatment outcomes, 15 (1.5%) were lost to follow-up, 43 (4.4%) defaulted and 24 (2.4%) died. In the logistic analysis, the odds of unsuccessful treatment outcomes were higher among elderly patients (AOR = 2.00, 95% CI 1.37–2.92), patients with extrapulmonary infections (AOR = 2.40, 95% CI 1.12–5.39), and with old cases of pulmonary TB (AOR = 3.03, 95% CI 1.47–7.19) when compared to their groups. Conclusions The study reported a treatment success rate of 91.7% among TB patients attending public hospitals in Kebbi State. The outcome was higher than the projected success rate of 85% set by the WHO. However, one-fourth of the total patients reviewed were not documented for treatment. Therefore, the need to design an appropriate recruitment strategy to identify and enrol those patients for an effective and successful TB control program in Nigeria.
Background: Blood transfusion is a known risk factor for transmitting infectious diseases, including the human immunodeficiency virus, due to false negatives and false positives in HIV rapid diagnostic test results. This study determines the percentage of false negatives and positives among prospective blood donors in two major referral hospitals in Kebbi State, Northwest Nigeria. Method: A total of 900 sera were collected from potential blood donors from January to July 2020 in two general hospitals in Kebbi State. All donors were screened for HIV infection using Determine HIV-1/2, Uni-Gold, and STAT-PAK. The presence of viral antigen in the donor serum was tested using the p24 diagnostic technique. Data were analyzed using SPSS version 16. Descriptive statistics were used to determine frequencies and percentages. The chi-square test compared categorical variables. Result: Out of 900 blood donors, 27 (3%) were reactive to determine HIV-1 and HIV-2. Onethird ( 9) of the 27 reactives on Determine HIV 1/2 were non-reactives on Uni-Gold. The nine (1%) non-reactive on Uni-Gold were also non-reactive on STAT-PAK and p24 viral antigens. The 873 (97%) samples that were non-reactive on Determine HIV 1/2, Uni-Gold, and STAT-PAK were non-reactive on HIV p24 antigens. The result showed that one-third of the blood donors who were not positive on determination were false positives, as confirmed on Uni-Gold, STAT-PAK, and the Ultra HIV Ag-Ab p24 antigen ELISA. Conclusion: The results suggest that using a lone rapid technique for HIV diagnosis is not recommended. Hence, a doubleblind strategy should reduce HIV endemicity and optimize blood safety.
