Leucocyte Phagocytosis In Children With Urinary Schistosomiasis And Asymptomatic Malaria Parasitemia

OG Arinola



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.

The Pattern Of Packed Cell Volume, Plasma Electrolytes And Glucose Levels In Patients Infected With Plasmodium falciparum

MF Olaniyan



Fifty-two patients (27 males, 25 females aged 25 &plusmn: 18.4 years) with Plasmodium falciparum infection and 53 healthy control subjects (27 males, 26 females aged 28.3 ± 19.2 years) were recruited for the study. Plasma electrolytes (Na+, K+, Cl), glucose and HCO3 were respectively analyzed colorimetrically and biochemically. There was an observed lower significant mean value of packed cell volume, Na+, HCO3and glucose in Plasmodium falciparum infected subjects than the values obtained from the normal control subjects with p < 0.05. Higher significant mean value of Cl and K+ was observed in the test than the control subjects (p < 0.05). Significantly lower packed cell volume, Na+, Cl, glucose and higher significant K+ levels were observed in the test subjects aged 1-10 years than test subjects aged 11-72 years with p < 0.05. This study further affirms the effects of Plasmodium falciparum infection on the pattern of packed cell volume, plasma electrolytes and glucose concentrations.

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

EI Ikeh, SN Akudo, VE Uguru



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
