Abstract

Malaria is one of the most common diseased conditions in Nigeria and  across most developing countries triggered by one of four species of Plasmodium. The objective of this study was to screen and detect for the presence of Plasmodium species via microscopic analysis on Malaria patients attending a healthcare facility Northern Nigeria and present the epidemiological data of malaria.Finger prick blood samples, Thick and Thin Giemsa-stained blood smears, were collected from 350 malaria-suspected individuals representing all age groups. The Giemsa-stained blood smears were examined microscopically. Demographic information on rural and urban dwellings, use of  insecticides and mosquito nets were collected using structured questionnaires. Malaria cases were detected in in 227 (64.9%) of the participants with a higher infection rate amongst the males (147) than the females (80). The  predominant specie found was Plasmodium  falciparum. All age groups in this study were vulnerable in the order of 61-above>31-40>51-60>41-50>1-10>21-30> 11-20 years of age.A large number of participants dwelling in urban area (219) were tested positive for malaria in contrast to eight(8) from the rural area. Not using insecticides and mosquito treated nets were significantly associated with the prevalence of malaria as 59.4% of participants who were tested positive for  Plasmodium falciparum infection utilized insecticides, while 66.9% of those who did not were also tested positive. Individuals residing close to gutters and bushes were the most susceptible (85.6%) to Plasmodium infection.

Abstract

Malaria in Pregnancy poses a serious health problem both for the mother and her unborn baby and this can be prevented with the use of Intermittent Preventive Treatment with sulphadoxine pyrimethamine (IPTp-SP), Long Lasting Insecticidetreated Nets (LLIN) and other preventive measures. This cross-sectional survey was carried out among pregnant women attending Ajeromi Ifelodun General Hospital between August 2013 and February 2014. A total of 414 pregnant women (with mean age of 29±8.7) in their first (84), second (124) and third (206) trimesters were recruited for this study. Blood samples for making both thin and thick smears were collected and semi-structured questionnaires administered to the respondents. The questionnaire probed into their knowledge on cause of malaria, the preventive measures taken against mosquito bite, use of IPTp-SP, possession and use of LLIN. The overall prevalence of malaria due to Plasmodium falciparum is 24 (5.8%) out of which 13 were primigravid, 5 were secundi-gravid, and 6 were multigravida with no significant difference (P>0.05) amongst them. Two hundred and eighty-six (69.1%) pregnant women had good knowledge of the cause of malaria. 164 (39.6%) of the sampled population had a tertiary education while 182 (44.0%) had secondary education, 124 (30.4%) were traders and 80(19.6%) were civil servants. Preventive measures claimed to be adopted by the respondents in avoiding mosquito bites include the use of LLIN (62.6%), insecticides sprays (36.2%), and locally adopted measures (1.5%). The number of respondents who had not availed themselves of IPTp-SP was significantly higher 258 (62.3%) compared to those who had (P<0.05). It was observed that educational status had no significant effect on the knowledge of the cause of malaria in sample population (p>0.05). The findings of this study reveal that there is a good knowledge on the cause of malaria among pregnant women but low use of IPTp-SP. In order to meet the new target of reaching an elimination stage set by the World Health Organization, factors responsible for the low use of these preventive measures should be investigated and quickly addressed so as to reduce both maternal and child morbidity/mortality resulting from malaria infection.

Paediatric malaria: a ten-year retrospective study at the national hospital, Abuja, Nigeria

IC Peletiri, JO Ajobiewe, NKO Ibecheozor

 

Abstract

A ten year study of malaria amongst paediatric patients was carried out in the Federal Capital Territory, Nigeria, West Africa from 2000 to 2010. Giemsa staining methodology was used. Of the 24 289 blood samples analyzed (comprising of 13 435 male children and 10 854 female children), 8668 (35·7%) were positive for malaria parasites. 267 (3·1%) had parasite density of > 5000 parasites/Zl of blood; 382 (4·4%) had between 500 – 5000 parasites/Zl of blood; 1262 (14·6%) had between 50 – 500 parasites/Zl of blood; while 6757 (77·9%) had between 5 – 50 parasites/Zl of blood. The 11-15 years age group had the highest prevalence of 40·6%, while neonates (<1 – 28 days), 1 month – 5 years, and 6 – 10 years age groups recorded 27·2%, 34.5% and 36·5% respectively. Of the 13 435 male children, 4845 (36·1%) had positive malaria result as against 35·2% (3823) of positive cases recorded among the 10854 female children. There is need to enhance parasitological diagnosis by way of providing diagnostic tolls at all levels of health care – primary (rural settings), secondary and tertiary. There are negative implications associated with the continued use of malaria rapid diagnostic tests (M-RDTs) methodologies which includes underdiagnosis, misdiagnosis of malaria and mismanagement of non-malarial fever, which wastes limited resources, erodes confidence in the health care system, and contributes to drug resistance. Finally, appropriate antimalarial drugs for treatment should be given free to all malaria positive children.

Laboratory diagnosis of malaria in children under five years in a rural community: microscopy versus malaria PF test

CP Enwuru, SI Umeh, UM Abasi, RC Egbuobi

 

Abstract

The morbidity and mortality associated with malaria in children below 5 years is really worrisome especially in the rural communities with little or no laboratory diagnostic facilities. This study was carried out to compare microscopy with Malaria Pf test for the diagnosis of malaria in a rural community in Ideato North Local Government Area of Imo State. Two hundred and fifty blood smears of children below 5 years were stained with Giemsa and examined microscopically for malaria parasites. Also the Malaria Pf rapid diagnostic test was used to test the same blood samples for malaria antigens. Thirty two per cent of the blood samples were positive for malaria parasite. Compared with microscopy, the sensitivity of the Malaria Pf test was 90.0%, the specificity was 98.2%. The positive predictive value was 96.0% and negative predictive value was 95.4%. The Malaria Pf test is reliable in the parasite based diagnosis of malaria in children under 5 years. We recommend the application of this test for parasitological confirmation of malaria in all places where it is not possible to provide facilities for good quality microscopy especially in the rural communities.

Plasmodium falciparium parasitemia in pregnancy in relation to maternal anaemia

R.A Akinboro, O Ojurongbe, A.A Akindele, O.A Adefioye, O.S Bolaji, O Olaniran, O.A Adeyeba

 

Abstract

This study was aimed at examining existing relationship between peripheral parasitaemia of Plasmodium falciparum and anemia among pregnant women in a secondary hospital and a tertiary hospital in Osogbo, South-Western, Nigeria. Two hundred and twenty five (225) patients were enrolled into this study, one hundred and fifty (150) from Asubiaro General Hospital, Osogbo and seventy five (75) from LAUTECH Teaching Hospital, Osogbo. A total of 30 (13.3%) women carrying the first pregnancy (primigravida), and 195 (86.6%) multiparous women (2-5) were enrolled. Mean age of recruited women was 31.511± SD 1.03, mean gestational age was 2.4267 ± SD 0.72 and mean packed cell volume was also 26.889 ± SD 0.43. Overall prevalence of malaria parasitemia was 63.6% while mean malaria parasite density was 461.33 among women infected with malaria parasite. Prevalence of malaria in pregnancy was highest amongst women with first pregnancy and in the age bracket 26 – 30 years (26.7%) and least among women greater than 40 years. Parasitemia decreased as parity increased, as women acquire immunity to malaria progressively with multiple pregnancies. Mild to moderate anaemia was also found to be prevalent among primigravida (11.6%) and this was associated with malaria parasitemia among these women .No correlated relationship was established between malaria parasitemia and age, gravidity, trimester of pregnancy, and Packed cell volume. Malaria chemoprophylaxis and other methods of malaria control should be sustained and advocacy for inclusion of malaria treatment in safe motherhood should be continued because of its beneficial potentials.

Leucocyte Phagocytosis In Children With Urinary Schistosomiasis And Asymptomatic Malaria Parasitemia

OG Arinola

 

Abstract

In the participants considered for this study, leucocyte migration, neutrophil candidacidal activity and ability to generate reactive oxygen were determined as percentage migration index (%M. I), candidacidal phagocytic index (%C.I) and bacterial stimulated nitroblue tetrazolium (NBT) dye reduction index (%NBT) respectively. Also, malaria density was counted from thick blood film of glass slide stained with Giemsa stain. The participants were 54 school children having urinary schistosomiasis without malaria parasites (USS-M), 18 children with both urinary schistosomiasis and malaria parasites (USS+M), 46 children with malaria parasites without urinary schistosomiasis (M-USS) and 29 controls. The mean % M.I was least while %NBT index was highest in USS+M subjects but M-USS subjects had least %C.I. Malaria density was higher in M-USS subjects than USS+M subjects. The results of this study showed that low prevalence and reduced severity of malaria parasites in children with urinary schistosomiasis may be due to adequate production of leucocyte migration inhibitory factor (LMIF) and reactive oxygen species.

Prevalence Of Malaria Parasitaemia In Pregnant Women Attending Antenatal Clinic At Jos University Teaching Hospital, Nigeria

EI Ikeh, SN Akudo, VE Uguru

 

Abstract

The prevalence of malaria parasitaemia in 200 pregnant women attending the antenatal clinic (ANC) of Jos University Teaching Hospital (JUTH) between April and June 2003 was determined. Geimsa-stained thick and thin blood films were examined microscopically for malaria parasites; the parasite densities were determined on the thick films. Eighteen (9%) of the women were positive for malaria parasites and only Plasmodium falciparum was encountered in the study. Pregnant women in the 15-20 year age group recorded the highest prevalence of 16%, closely followed by the age group 21-25 years with 15.2%. The 26-30, 31-35, 36-40 and 41-50 year age groups recorded 6.7%, 4.5%, 4.1% and 0% prevalence rates respectively. Women in their first trimester recorded 13.3% as against 10.2% and 3.8% for the second and third trimester respectively. The primigravidae had a prevalence of 12.9% as against 7.2% for multigravidae. Most of the women with malaria parasitaemia (89%) had parasite densities of less than 1000/µL of blood. The low prevalence of malaria parasitaemia in the ANC women is attributed to the regular prophylactic malaria therapy and the impacts of the health talks normally given to pregnant women during routine antenatal visits

Review Article: Epidemiology of Malaria in Africa

TM Akande, IO Musa

 

Abstract

Malaria is a life threatening parasitic disease transmitted by female anopheles mosquitoes. There are four types of human parasites; Plasmodium vivax, P. malariae, P ovale and P. falciparum. P. falciparum and P. vivax are the most common and P. falciparum, the most deadly type of infection, is most common in sub-Saharan Africa. A large number of environmental factors affect the distribution, seasonality and transmission intensity of malaria. Rainfall provides breeding sites for mosquitoes and increases the humidity, which enhances their survival. While malaria is largely endemic in Africa, varying proportion of countries in the continent are at risk of endemic malaria. Today, approximately 40% of the world population, mostly those living in the world’s poorest countries, is at risk of malaria. This is mostly in the tropical and sub-tropical regions of the world. There are at least 300 million acute cases of malaria each year globally resulting in more than a million deaths, around 90% of these occur in Africa, mostly young children. In areas of stable malaria transmission, very young children and pregnant women are the population at highest risk for malaria morbidity and mortality. The populations most at risk of epidemics are those living in highlands, arid and desert-fringe zones and those living in areas where successful control measures have not been consolidated or maintained.

Review Article: ‘Miasma’ Theory and the Possibility of Malaria Eradication

Ademola O Awoyemi

 

Abstract

Malaria as a disease entity caused by plasmodium species only became recognized towards the end of the 19th Century. Prior to that time, Mal’aria or ‘bad air’ was believed to be the cause of fevers or paludal. This article traces the history of ‘Miasma’ theory which had been accepted for Centuries before the ‘Germ’ theory became established. Comparing the ‘Miasma’ theory with current understanding of Africans about disease causation, it was concluded that there are great similarities. It is therefore recommended that concurrent application of both the ‘Germ’ theory and the ‘Miasma’ theory could lead to a more effective control or even global eradication of malaria.
