Blood transfusion saves lives and reduces morbidity and mortality for a large number of diseases and clinical conditions, but it is not without danger. The aim of this study was to determine the seroprevalence of HIV and hepatitis B in blood donors received at the regional Blood Transfusion Centre of N’Zérékoré (Guinea). This was a 5-year retrospective analytical study. We included records of blood donors aged 18 to 60 years admitted to the N’Zérékoré Regional Blood Transfusion Centre for blood donation from January 2016 to December 2020. We performed a descriptive analysis followed by Chi-2 or Fish-er-exact tests and the Student or Wilcoxon test, followed by multivariate logistic regression. In this study, donor age ranged from 18 - 60 years, with a pre-dominance of donors aged 25 - 34 (44.2%). Male donors were the most represented in our study (79.0% versus 21.0% female). More than half of the donors were blood group O (55.6%). We observed a seroprevalence of 3.6% for HIV, 13.4% for HBsAg and 0.2% for co-infection. In our series, age 25 - 34 (OR = 1.89 and P = 0.001) and 35 - 44 for HIV (OR = 2.01 and P = 0.001), HBsAgserostatus (OR = 3.04 and P = 0.001) and blood donation history (OR of 3.04 and P = 0.001) were factors associated with HIV positivity (P < 0.05). In our study, HIV serostatus (OR = 3.04 and P = 0.001) and blood donation history (OR = 0.01 and P = 0.001) were factors associated with HBsAgseropositivity. We reported a high prevalence of HIV and HBsAg. Sex, serological status and blood donation history were associated factors.

Gastroenteritis constitutes a group of diarrheal diseases of infectious origin, responsible for absenteeism from work, morbidity and mortality, especially among aged people. This study aimed to evaluate the antibacterial activity of Mitragyna inermis extracts on the in vitro growth of Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa involved in gastroenteritis. Phytochemical screening was carried out using two distinct methods. The detection of phytochemical compounds by tube coloring and chromatography on a thin layer of silica gel. The sensitivity of organisms was evaluated by the agar well method. The dilution method in liquid medium coupled with spreading on Mueller Hinton agar helped determine the CMB/MIC activity ratios. The investigations show that the extract has the best extraction yield (75.86% ± 0.20%) compared to the aqueous macerated (61.8% ± 0.08%) and decocted (66.6% ± 0.12%). These extracts contain several phytochemical compounds such as flavonoids, polyphenols, tannins, alkaloids, saponosides, coumarins and sterols and terpenes. These substances are endowed with biological activities and could be at the origin of antibacterial activity observed with M. inermis extracts. The analysis of antibacterial activity showed that the germs are sensitive to the extracts with inhibition diameters ranging from 8.30 ± 0.53 to 17.87 ± 0.58 mm. The ethanolic extract was the most active with diameters varying from 15.07 ± 0.62 to 17.87 ± 0.58 mm on all the germs tested. E. coli and S. aureus were the most sensitive germs to the extracts. P. aeruginosa was the least sensitive germ. Activity reports indicate that the extracts exert bactericidal activity on E. coli and S. aureus but bacteriostatic activity on P. aeruginosa. These results justify the use of M. inermis leaves in a traditional environment to treat gastroenteritis.

Introduction: Acute poisoning in children is cause of hospitalization and death worldwide. It is a Paediatrics emergency with significant economic cost. There are epidemiological differences in acute poisonings in children evaluated in Emergency departments across different countries and regions of the world. The aim of this study was to determine the causes of poisoning in children in our health facility during the period 2000-2019. Methodology: Case notes of children 6 months to 18 years managed for acute poisoning from January 2000 to December 2019 at Paediatrics unit, Federal Teaching Hospital gombe (FTHG), were analysed. The International classification of Disease ICD 10 was used. Ethical Clearance was obtained. Results: 26,716 children were admitted with 76 cases of Acute poisoning giving a prevalence rate of 2.8/1000 children. 56.6% (43) were males. 63.2% (48) of children were years of age. 69.7% (53) were urban dwellers and 59.2% (45) from low socioeconomic class. 52.6% (40) of poisoning occurred in rainy season. 97.3% (74) of children had unintentional poisoning. Organophosphates 22.3% (17) and kerosine 22.3% (17) were the most common substances ingested. Snake-bite and corrosive ingestion occurred in 13.1% and 11.8% of children respectively. Ingestion was the route in 84.2% of cases. 75.0% (57) of poisoning occurred at home. ACP occurred in children aged 1 - 5 years (p-value = 0.025);More in Children from low socioeconomic status (p-value = 0.001) and urban settings (p-value = 0.001). There was no statistically significant relation between type of poisoning and gender p = 0.839, season p = 0.608, religion p = 0.504 and ethnic background p = 0.342. 4.2% (3) children died each from organophosphate, snake bite and tramadol poisoning. Conclusion: Kerosine and organophosphate were the leading cause of accidental childhood poisoning.

Background: Despite years of Paediatric Antiretroviral therapy in Nigeria, the National implementation plan for the scale up of viral load testing was only rece ntly launched. Viral load determination is the most important indicator of ART response. Material & methods: First viral load samples were collected from 663 children living with HIV between December 2017-Decemb er 2019 aged 0 - 18 years on highly active antiretroviral therapy from 4 states within Nigeria. Samples were analyzed at a Polymerase Chain Reaction laboratory of the Federal Teaching Hospital gombe. Results: Males were 311 (46.9%) and 352 (53.1%) female. Children aged 0 - 9 years constituted 44.9% (298);55.1% (365) were aged 10 - 18 years. This first viral load was primarily routine in 94 .2% (625);2.9% (19) of children respectively had suspected clinical or immunological failure. ART combination was AZT/3TC/NVP in 78.1% (518/663) of CLHIV;TDF/3TC/EFV in 21.2% (141);AZT/3TC/LPV/rtv in 4 (0.6%). Prior to initiation of routine viral load testing $0.55 (366/663) CLHI V had received HAART for 1 - 5 years;7.8% (52/663) for 6 months but 10 years. The most recent CD4 count before viral load request was ≥1000/μL in 24.7% (164) of CLHIV;500 - 999/μL in 42.9% (285);350 - 499 μL in 11% (73) and 1000 c/ml in 59.9% (174/311) males and 47.2% (166/352) females. Viral load was significantly lower among females (P-value 0.02). Of children aged 0 - 9 years 50.3% (150/298) had viral load > 1000 c/ml and 10 - 18 years 52.1% (190/365) (P value 0.660). Viral load was >1000 c/ml in 38.5% (20/52) of children on HAART for 6 months - 1 year and 52.2% (191/366) after receiving HAART for 1 - 5 years. 52.3% (114/218) and 55.6% (15/27) CLHIV had viral load > 1000 c/ml after receiving HAART for 6 - 10 and >10 years respectively (P value 0.29).

Background: The adult ART (antiretroviral therapy) programme started in Nigeria in 2002. After many years of ART in the country, the National implementation plan for the scale up of viral load testing was launched in 2016. Viral load estimation is the most important indicator of ART response. Aim: To describe viral suppression in adults on the HIV ART programme Material & methods: Viral load blood samples of 9450 adults on highly active antiretroviral therapy living with HIV from 4 states within Nigeria were analyzed for HIV RNA in Polymerase Chain Reaction laboratory of the Federal Teaching Hospital, gombe between December 2017 and December 2019. Results: Males were 2577/9450 (27.3%) and 6873 (72.7%) females. Adults aged 26 - 45 years constituted 69.5% (6572). Viral load test was primarily routine in 96.3% (9098). ART was AZT/3TC/NVP in 52.5% (4962);TDF/3TC/EFV in 46.3% (4375). 48.3% (4568/9450) adults had received HAART for 1 - 5 years;7.4% (699) for 6 months but 10 years. The most recent CD4 count before viral load request was ≥1000/μL in 6.5% (612) of adults;500 - 999/μL in 38.6% (3651);350 - 499 μL in 23.2% (2195) and 1000 c/ml in 22.8% (587/2577) males and 23.0% (1580/6873) females. Of adults aged 19 - 25 years, 28.4% (211/743) had viral load >1000 c/ml;23.5% (1544/6572);20.0% (294/1473);17.8% (93/523) and 18.0% (25/139) aged 26 - 45 years, 46 - 55 years;56 - 65 years and >65 years also had viral load >1000 c/ml (p value 1000 c/ml in 26.0% (182/699) of adults on HAART for 6 months - 1 year and 21.3% (975/4568) after receiving HAART for 1 - 5 years. 24.9% (885/3551) and 19.8% (125/632) adults had viral load > 1000 c/ml after receiving HAART for 6 - 10 and >10 years respectively.

Introduction: Viral hepatitis is a major public health challenge that requires an urgent response. Reducing mortality requires major scale-up in prevention, testing and treatment access;coverage in HBV vaccination, testing and treatment is low and must accelerate massively to achieve the 2030 targets. Less than 1% of HBV-infected individuals are diagnosed in Sub-Sahara Africa, despite the availability of rapid tests with good diagnostic accuracy. Materials and Methods: This was retrospective cross sectional study conducted in Federal Teaching Hospital gombe, in North East Nigeria. All children and adults who presented to the out-patient departments, and those that were admitted irrespective of their HIV and or Hepatitis C virus status and had Hepatitis B and/or Hepatitis B envelope antigen test were conducted between 2000 to 2015. All children and adults were tested using the Hospital standard for Hepatitis B surface antigen test strip. Results: Between 2000 and 2014, 739,456 children and adults were admitted and reviewed in the outpatient units of the Federal Teaching Hospital gombe;there were 685,552 adults and 53,904 children. Children constituted 7.3% (53,904/739,456) of admissions and outpatient consultations. 2.8% (210/7570), 3.3% (773/23,783), 3.6% (1145/32,142), 5.2% (1694/33,043), 3.3% (986/29,216), 1.9% (661/3321), 0.1% (53/41,626), 0.2% (113/46,634), 2.6% (1418/54,423), 5.4% (3717/69,696), 3.7% (2332/62,086), 3.5% (3241/90,623), 3.2% (2881/89,398), 3.8% (2428/62,687), 2.8% (1835/63,208) of children and adults were tested for HBsAg in 2000, 2001, 20002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 and 2014 respectively. 23,487 children and adults were tested for HBsAg with a cumulative testing rate of 3%. Overall 4465/23,487 children and adults were seropositive for HBsAg giving a cumulative prevalence of 19%. Conclusion: HBV screening in our health facility is very low

Introduction: Automated blood culture systems for incubation and growth monitoring have become the standard in high-income countries (HICs), but are still relatively expensive and not universally available for implementation in most low- and middle-income countries (LMIC). We aimed to report blood culture isolates using Automated technique in children and adults admitted into the Federal Teaching Hospital gombe from 2016 to 2020. Materials and Methods: Blood Culture Isolates in children (0 - 18 years) and adults (>19 yrs) by Bactec 9050 Automated culture system from 2016-2020 were retrieved from the medical and laboratory register. Information analyzed included, age, sex, month, and year and culture growth and reported antibiotic sensitivity. A Bactec Blood culture tests is $20 in this facility. In Nigeria, the minimum monthly wage is $70 (Official currency exchange rate is N423/US Dollar). Results: Of the 1713 blood cultures performed, children 0 - 18 years were 1322 (77.2%) and adult (19 years above) (22.8%). Overall positivity was 733 (42.2%) with males 385 (52.5%). Of the 1322 Blood cultures (BC) in children 615 (46.5%) were positive for isolates and adults 118 (30.2)%. Blood culture positivity decreased with increasing age with newborns 251 (34.5%) and adults > 65 years 18 (2.5%). Staphylococcus aureus constituted 61.3% of all isolates and was the leading isolates in all age groups;Alkaligenes (9.1%);Citrobacter 8.1%, Klebsiella 6.7%;Pseudomonas 6.1%;E. coli 2.7%;Enterococcus 2%;Proteus 1%.

Introduction: Transitioning to more efficacious Antiretrovirals for HIV infected pregnant women and infant prophylaxis has reduced Mother to child transmission of HIV significantly. This study aimed to determine HIV infection status in HIVexposed infants who had their first DNA polymerase chain reaction test in our molecular Laboratory. Subjects, Materials and Methods: Dried Blood Spots for HIV DNA results from 5 states between 2009 and 2020 were analyzed in the PCR laboratory of the Federal Teaching Hospital, gombe. Results: Nine thousand eight hundred and twenty-three Human Immunodeficiency Virus Deoxyribonucleic acid polymerase Chain Reaction results were analysed;4937 (50.2%) were males. During the study period, there was an overall declining trend in the mother-to-child transmission rate from 3.8% in 2009 to 1.0% in 2020. 6120 (62.3%) of HIV + mothers received Highly active antiretroviral therapy HAART before pregnancy. 7845 (76.2%) of the infants received Nevirapine prophylaxis. Dried blood spot samples were collected from 4077 (41.5%) at 6 - 8 weeks. 8438 (85.9%) received cotrimoxazole. 9469 (96.4%) were ever breastfed. Of the 9823 HIV DNA PCR results, 255 (2.6%) were positive while 69/4077 (1.7%) and 109/2662 (4.1%) were positive for HIV DNA at 6 - 8 weeks and > 12 weeks respectively. (p = 0.001). 86/747 (11.5%) of infants whose HIV-positive mothers received no ARVS were HIV DNA positive. (p = 0.001). 106/884 (12.0%) of infants who had no Antiretroviral prophylaxis had positive HIV DNA results;7/413 (1.7%) with Zidovudine/Nevirapine prophylaxis had positive results. (p = 0.001). 246/9469 (2.6%) of infants that were ever breastfed were positive for HIV DNA;11/354 (3.0%) that never breastfed had positive HIV DNA. Conclusion: Lack of maternal/infant ARVs and prolonged breastfeeding increased the risk of infant HIV infection.
