It was a major breakthrough for human medicine when Landsteiner discovered the ABO blood group system. But with the discovery of ABO and Rhesus systems, this major hindrance to safe blood transfusion- and by extension surgery- was effectively put behind humanity. Centuries after this, humanity is faced another kind of challenge to safe blood transfusion- transfusion transmitted infections (TTIs), particularly in developing nations of the world. Though lots of infections are transmissible through transfusion, the focus of this study was HIV, HBV, HCV and syphilis. This study aimed at determining the prevalence of these TTIs (HIV, HBV, HCV and syphilis) among intending blood donors at a tertiary health facility in Ekiti State, southwest, Nigeria. The data of 150 intending blood donors at the said tertiary health facility were retrospectively retrieved and analysed. One hundred and twenty (80%) of the subjects were males, while 30 (20%) were females. The age of the subjects ranged between 18 and 55 years. Thirty-four (22.7%) of the subjects had TTIs, while 116 (77.3%) were negative to all the TTIs of interest for this study (HIV, HBV, HCV and Syphilis). Out of the 34 subjects who had TTIs, 2 (1.3%) tested positive for HIV, 18 (12%) for HBV; 10 (6.7%) for HCV and 4 (2.7%) for syphilis. Twenty-nine (85.3%) of the subjects who had TTIs were males, while 5 (14.7%) were females. An overall TTI sero-prevalence of 2.7% is rather on the high side and should serve as a wake-up call to all concerned authorities in the State to design enlightenment programme that will reduce the sero-prevalence of TTIs.
Background: Although chloroquine (CQ) has been officially replaced with artemisinin combination therapy (ACT) as first line drug for the treatment of malaria in Nigeria since 2005, a lot of people still believe that chloroquine is more effective chiefly because of the decline in the sensitivity of Plasmodium falciparum to ACT. Thus resulting into unofficial use of CQ for self medication. This study was conducted in order to survey the current status of chloroquine resistant strains of pfcrt and pfmdr1 in view of possible re-introduction of chloroquine for malaria treatment. Methods: DNA was extracted from one hundred (100) microscopically confirmed Plasmodium falciparum positive blood samples spotted on 3 mm Whatman filter paper. The detection of mutations in Plasmodium falciparum chloroquine resistance transporter (Pfcrt) and Plasmodium falciparum multidrug resistance (Pfmdr1) genes was performed by nested polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP). Results: Results showed the presence of mutant alleles of Pfcrt and Pfmdr1 in 60% and 41% of the samples respectively. However, there was no significant correlation in the prevalence of mutant alleles (T76/Y86) in relation to gender (p = 0.59/ 0.08) and age (p=0.59/0.93) of participants respectively. Conclusion: The observed high prevalence of chloroquine resistance despite thirteen years of withdrawal calls for serious concern.
Viral hepatitis is a serious disease of the liver that can have grim prognosis in the absence of early and appropriate medical intervention. Globally, an estimated two billion people are reported to have been infected with hepatitis B virus (HBV) and out of this, more than 350 million are said to have chronic(long term) liver infection. The likelihood that Hepatitis B Virus infection will become chronic depends upon the age at which a person becomes infected. Young children who become infected with HBV are most likely to develop chronic infection. About 25% of adults who become chronically infected during childhood die from HBV related liver cancer or cirrhosis. According to WHO ranking of hepatitis prevalence, ≤ 1.9%, 2-7.9% and ≥ 8% are low, moderate and high prevalence respectively. Hepatitis is endemic in Ekiti State, there is therefore the need to know its prevalence in the major cities of Ekiti State. Since Ikere-Ekiti is the second major city of Ekiti State, therefore this study set out to know the prevalence of HBV-caused hepatitis in Ikere-Ekiti and its associated factors,. One hundred participants were enrolled- at the State specialist Hospital, Ikere-Ekiti- into the study after obtaining their informed consent. Consecutive sampling was used. Thirty-three (33%) of the subjects were males while 67 (67%) were females. Thirty-seven (37%) , 30 (30%) and 33 (33%) respectively fell were in the ≤26 years, 27-36 and ≥37 age-brackets. Fifty-two (52 %) were singles while 48 (48%) were married. Ninety-three (93%) were Christians while 7 (%) were Muslims. Structured self-administered questionnaires were served on the subjects. Five millilitres of blood were collected from each subject using venepuncture method. The samples were screened for the presence or otherwise of antibodies to HBsAg using a rapid test kit that worked on the principle of immunochromatography. An overall prevalence of 8% was discovered. Five (5%) of the positive subjects were males while 3 (%) were females (p=0.064). Half (50%) of the positive subjects were within the ≤26 years age-bracket, the 27-36 age-bracket had the least number of positive subjects (p=0.512). Two out of the positive subjects had a history of blood transfusion (p=0.748), one had history of surgery (p=0.580). The imports and implications of these are here discussed. Since viral hepatitis is vaccine-preventable and herd immunity can only be achieved when the vast majority of a society acquires immunity against a particular infectious disease, the government is advised to strive to vaccinate at least 70% of the populace against viral hepatitis- a disease which is endemic, not only in Ekiti State, but in many parts of Nigeria.
Background: Nine out of every 10 of the world’s 1.8 billion adolescents and young people (AYP) live in developing nations, Nigeria inclusive. In Nigeria as in the rest of sub-Saharan Africa, 1 out of every 3 persons is an adolescent or a young person. As at 2016, there were about 240, 000 AY) aged 10-19 years in Nigeria, which roughly makes 7% of the total number of people living with HIV (PLWH) in Nigeria. According to 2017 national survey, about 70% of the country’s AYP lack knowledge of how HIV is transmitted or how it can be prevented. Since AYP, aged 10-19 years, constitute a significant proportion of the nation’s burgeoning population, it is very important and critical to fully understand the dynamics of the HIV epidemic among AYP. This study aimed at determining the prevalence of HIV among AYP at a tertiary health facility in Ekiti State, Southwest Nigeria and comparing it with national and regional prevalence among same group. Methodology: The study was a retrospective study of AYP, aged 13-20 years at Ekiti State University Teaching Hospital, Ado-Ekiti, Ekiti State, Southwest Nigeria. Convenience and consecutive sampling method was used in retrieving subjects’ data. One hundred subjects whose ages were between 13 and 20 years were consecutively sampled over a period of six months, July to December, 2018. Results: Out of the one hundred subjects retrospectively sampled, 46 (46%) were males, while 54 (54%) were females. Four (4%) of the subjects were 13 years of age, while 6(6%), 5(5%), 8(8%), 27(27%), 17(17%), 12(12%) and 21(21%) respectively were aged 14, 15, 16, 17, 18, 19 and 20 years. Three (3%) of the subjects were positive to HIV, 1 (%) was male, while 2 (20%) were female, thus giving a sero-prevalence rate of 3%. Disaggregation of the positive subjects reveals that 33.3% were male, while 66.7% were females. Conclusion: Though the general prevalence of HIV in Ekiti State ranks among the lowest in Nigeria, group-specific interventions targeting the AYP should be put in place in the State to address the disproportionately high prevalence among the AYP in the State.
Journal of Biosciences and Medicines tive and positive subjects' questionnaires were carried out, so as to determine the probable risk-factors that predisposed the positive subjects to infection. Hypotheses tested at p < 0.05 revealed that there was a significant difference in the rate at which the subjects were infected with HIV among the age-groups.
