This study was carried out to determine the presence of intestinal parasites and their correlation with CD4+ T-cell counts and demographics among human immunodeficiency virus (HIV)-positive patients in Benin City, Nigeria. Stool specimens from 2,000 HIV-positive patients and 500 controls (HIV-negative individuals) were examined for ova, cysts, or parasites, using standard procedures. In addition, patient's blood samples were analyzed for CD4 counts by flow cytometry. An overall prevalence rate of 15.3% was observed among HIV-positive patients while 6.2% was noted among non-HIV subjects. HIV status was a significant (P<0.0001) risk factor for acquiring intestinal parasitic infections. Male gender, CD4 count <200cell/µl, and diarrhea were significantly associated with an increased prevalence of intestinal parasitic infections among HIV-positive patients. The level of education, occupation, and source of water among HIV patients significantly (P<0.0001) affected the prevalence of intestinal parasitic infections. Ascaris lumbricoides was the most predominant parasite in both HIV-positive patients and controls. A CD4 count <200 cells/µl was significantly associated with only Isospora belli and Cryptosporidium infections. The presence of pathogenic intestinal parasites such as A. lumbricoides, hookworm, Giardia intestinalis, Entamoeba histolytica, Trichuris trichiura, and Taenia species among HIV-infected persons should not be neglected. Cryptosporidium species and I. belli were the opportunistic parasites observed in this study. Routine screening for intestinal parasites in HIV-positive patients is advocated.

Aim:To determine the prevalence of urinary tract infection (UTI) in Okada, a rural community in Nigeria, and the effect of age and gender on its prevalence as well as the etiologic agents and the susceptibility profile of the bacterial agents.Patients and Method:Clean-catch midstream urine was collected from 514 patients (49 males and 465 females). The urine samples were processed and microbial isolates identified. Susceptibility testing was performed on all bacterial isolates.Result:The prevalence of urinary tract infection was significantly higher in females compared to males (female vs. male: 42.80% vs. 10.20%; OR = 6.583. 95% CI = 2.563,16.909; P < 0.0001). Age had no effect on the prevalence of UTI. Escherichia coli was the most prevalent isolate generally and in females, while Staphylococcus aureus was the predominant isolate causing urinary tract infection in males. The flouroquinnolones were the most active antibacterial agents.Conclusion:An overall prevalence of 39.69% was observed in this study. Females had a 3 to 17 fold increase risk of acquiring UTI, than their male counterpart. Escherichia coli were the predominant isolates causing UTI.

BACKGROUND: A good proportion of pregnant women patronize traditional birth homes in Nigeria for ante-natal care. This study aimed at determining the prevalence, risk factors, and susceptibility profile of etiologic agents of urinary tract infection among ante-natal attendees in a traditional birth home in Benin City, Nigeria. METHODS: Clean-catch urine was collected from 220 pregnant women attending a traditional birth home in Benin City, Nigeria. Urine samples were processed, and microbial isolates identified using standard bacteriological procedures. A cross-sectional study design was used. RESULTS: The prevalence of urinary tract infection among pregnant women was 55.0%, significantly affected by parity and gestational age (P<0.05). Mixed infection was recorded among 13(10.7%) pregnant women, and was unaffected by maternal age, parity, gravidity, gestational age, and educational status. Irrespective of trimester Escherichia coli was the most prevalent etiologic agent of urinary tract infection, followed by Staphylococcus aureus. The flouroquinolones were the most effective antibacterial agents, while Sulphamethoxazole-trimetoprim, Amoxicillin, Nalidixic acid, and Nitrofurantoin had poor activity against uropathogens isolated. CONCLUSIONS: The prevalence of urinary tract infection among pregnant women was 55.0% and significantly affected by gestational age and parity. The most prevalent etiologic agent observed was Escherichia coli. With the exception of the flouroquinolones, aminoglycoside, and Amoxicillincluvanate, the activity of other antibiotics used on uropathogens were poor. Health education of the traditional birth attendant and her clients by relevant intervention agencies is strongly advocated.

Abstract:The aim of this study was to use the World Health Organization (WHO) definition of anaemia to determine prevalence of anaemia among human immunodeficiency virus (HIV)-infected patients on the highly active antiretroviral therapy (HAART) and those that are HAART naive. Haemoglobin concentration was measured in 457 HIV patients consisting of 217 patients on HAART (86 males and 131 females) and 240 HAART naive patients (106 males and 134 females). According to WHO criteria, anaemia was defined as a haemoglobin concentration below 12g/dl in women and below 13g/dl in men. The anaemic HIV patients were further categorized according to WHO/ACTG anaemia toxicity grades. An overall anaemia prevalence of 60.61% was observed. The prevalence of anaemia was significantly higher among HAART naive patients (69.17%) than in HIV patients on HAART (51.15%) (P < 0.001). The prevalence of anaemia differ significantly (P < 0.05) between males and females of HAART naive patients with males (76.42%) having higher prevalence than females (63.43%). The WHO/ACTG categorization showed the same pattern between HIV patients on HAART and those that were HAART naive. Conclusively, the overall prevalence of anaemia was 60.61% among HIV patients. HAART naive patients have higher prevalence as well as males in this group. The WHO definition of anaemia is recommended as this will give the true prevalence of anaemia and allow for policy and interventions to address it. _______________________________________________________________________________________

Background: The traditional birth attendant delivers majority of pregnant women in Nigeria. Objective: This study aimed at determining the prevalence and associated risk factors for delivery of low birth weight (LBW) neonates in a Traditional Birth Home (TBH)in Benin City, Nigeria. Methods: A total of 780 pregnant women who received ante-natal care at a TBH and live singletons born to them were recruited for this study. Venous blood was collected from all pregnant women at onset of labour, and haemogblobin concentration determined using standard method. Results: The prevalence of low birth weight was 6.3%, and was significantly affected by maternal age (P =0.039), gestational age (P=0.019), maternal height (P = 0.001), marital status (P = 0.015), and time of registration (P = 0.016). Being in a polygamous union, was significantly associated with the prevalence of LBW (OR = 13.640; 95%CI: = 6.148, 30.261; P = < 0.0001). Maternal anaemia was identified as a risk factor for the delivering of LBW neonates (OR = 2.797; 95% CI = 1.555, 5.029; P = 0.0001). Conclusion:The prevalence of low birth weight was 6.3%. Intervention by appropriate agencies is advocated to reduce LBW in TBHs in Nigeria.

Background:Otitis Media continues to be a major presentation in the ear, nose and throat clinic.Aim:This study aimed to isolate, characterize and identify the bacteriological and mycological etiologic agents of otitis media in Benin city.Patients and Methods:Ear discharge from 569 (299 males and 270 females) patients diagnosed clinically of otitis media between August 2009 and August 2010 were processed to recover the bacterial and fungal etiologic agents. Susceptibility test was performed on all bacterial isolate.Result:Pseudomonas aeruginosa (28.3%) was the predominant bacteria isolate causing otitis media followed by Staphylococcus aureus (21.0%), Klebsiella sp (8.9%), Proteus sp (8.2%), Alkaligenes spp (4.3%), Streptococcus pneumoniae (3.9%), Escherichia coli (3.0%) and Citrobacter freundi (1.7%). Fungi isolated were Aspergillus niger (9.2%), Candida albicans (5.4%), Candida tropicalis (3.0%), Aspergillus flavus (2.1%) and Candida parasilopsis (1.5%). 413 had a single organism isolated from the middle ear culture while twenty (3.51%) patients had mixed organisms isolated. Infection was highest among 0 - 5 years, and lowest among aged 18 - 23. All bacterial isolates were poorly susceptible to the antibacterial agents.Conclusion:The study uncovers a high frequency of bacteria associated otitis media with the finding of fungi too as a significant etiologic agent.
