Accelerating HIV epidemic control in Benue state, Nigeria, 2019-2021: the APIN program experience.

Introduction: As at 2019, Nigeria was ranked the fourth highest HIV burden in the world. There is varied geographical HIV prevalence in Nigeria. The progress made is inequitable across geographical locations and sub-populations (18). Benue state has the second highest HIV prevalence in Nigeria. In 2018, about 35,623 people living with HIV (PLHIV) were yet to commence antiretroviral treatment (ART) in the state, accounting for an estimated ART coverage gap of 11% out of the combined gap of 320,921 in the country. To close this gap, the Benue ART surge (BAS) was implemented. The aim of this study was to describe the BAS strategic approaches and demonstrate progress in expanding ART access for PLHIV in Benue State, Nigeria. Methods: BAS was implemented in 252 health facilities from May 2019 to September 2021. Data were collected and reported using an Excel-based dashboard and electronic medical records. The trend of HIV case identification, ART initiation, viral load suppression rate, and rate of interruption in treatment during the BAS period was then described and analyzed. Results: Out of 893,462 clients reached, 6.7% (n = 60,297) were diagnosed with HIV and 99.8% (n = 60,236) were initiated on ART. HIV case identification per month increased by 467% from 650 at baseline to a peak of 3685 in August 2020, and then declined by 35% to 2380 in September 2021. All new HIV-infected patients (100%) were linked to ART. Viral load testing coverage and viral load suppression rate increased from 30% (43,185/126,004) and 84% (n = 36,165/43,185) at baseline to 95% (n = 193,890/204,095) and 96% (185,785/193,890), respectively. Conclusion: Implementation of the BAS improved access to comprehensive HIV services in Benue State. The increase in HIV case identification and ART initiation significantly reduced the HIV treatment gap in the state. To fast track the attainment of UNAIDS 95-95-95 goals, lessons learnt from the BAS should be adapted and scaled up in the national HIV program in Nigeria.

Phenotypic and Molecular Characterization of ß-Lactamases among Enterobacterial Uropathogens in Southeastern Nigeria.

Little is known about the molecular basis of antibiotic resistance among uropathogens in Southeast Nigeria. The aim of the study was to characterize enterobacterial uropathogens with respect to drug resistance. One hundred (100) enterobacterial uropathogens were studied. Their antibiotic susceptibility patterns were evaluated using disk diffusion, screened, and confirmed phenotypically for the presence of ß-lactamases: ESBL, AmpC, carbapenemase, and MBLs. Screen positives were further tested for various ß-lactamase genes by PCR. Our isolates showed variable resistance to most drugs tested. Out of the 58 ESBL screen positive E. coli, 35 were confirmed positive with PCR. The predominant ESBL gene was blaTEM while blaSPM was the most prevalent among MBL genes. Forty-six percentage of the screen positive Salmonella isolates coharbored blaTEM + SHV genes. Nine of the 10 ESBL screen positive K. pneumoniae were phenotypically and PCR positive. Three isolates of K. pneumoniae were positive for MBL genes. All the 10 C. freundii were positive for ESBL genes. The study showed high prevalence of drug-resistant genes among the enterobacterial uropathogens. Majority of the uropathogens harbored >1 antibiotic-resistant gene, and the most predominant gene was ESBL (blaTEM) followed by the MBL (SPM) gene.

Effect of addition of ripe bananas on some physico-chemical properties of maize 'extract'.

Flour mixes obtained by the addition of banana pulp in various proportions (0-50%) to maize 'extracts' were evaluated for some quality characteristics. All the mixes had significantly lower values of crude protein, fat and water-holding capacity. Gelation, however, significantly increased the water-holding capacity in all cases. The ash content, titratable acidity and total sugars increased tremendously with an increase in the level of banana substitution. While both Adam's consistency values and equilibrium moisture content decreased with an increase in the level of banana substitution, the syneresis values did not show any consistent pattern. The consistently low moisture content and the results of the moisture sorption isotherms suggest a good storage stability of all the mixes, especially when kept under conditions of water activity of 0.30 and below, and their possible suitability for baked products.
