Chloroquine resistant Plasmodium falciparum malaria in Osogbo Nigeria: efficacy of amodiaquine + sulfadoxine-pyrimethamine and chloroquine + chlorpheniramine for treatment.

Abstract: Chloroquine (CQ) resistance in Plasmodium falciparum contributes to increasing malaria-attributable morbidity and mortality in Sub-Saharan Africa. Despite a change in drug policy, continued prescription of CQ did not abate. Therefore the therapeutic efficacy of CQ in uncomplicated falciparum malaria patients was assessed in a standard 28-day protocol in 116 children aged between six and 120 months in Osogbo, Southwest Nigeria. Parasitological and clinical assessments of response to treatment showed that 72 (62.1%) of the patients were cured and 44 (37.9%) failed the CQ treatment. High initial parasite density and young age were independent predictors for early treatment failure. Out of the 44 patients that failed CQ, 24 received amodiaquine + sulphadoxine/pyrimethamine (AQ+SP) and 20 received chlorpheniramine + chloroquine (CH+CQ) combinations. Mean fever clearance time in those treated with AQ+SP was not significantly different from those treated with CH+CQ (p = 0.05). There was no significant difference in the mean parasite density of the two groups. The cure rate for AQ+SP group was 92% while those of CH+CQ was 85%. There was a significant difference in parasite clearance time (p = 0.01) between the two groups. The 38% treatment failure for CQ reported in this study is higher than the 10% recommended by World Health Organization in other to effect change in antimalarial treatment policy. Hence we conclude that CQ can no more be solely relied upon for the treatment of falciparum malaria in Osogbo, Nigeria. AQ+SP and CH+CQ are effective in the treatment of acute uncomplicated malaria and may be considered as useful alternative drugs in the absence of artemisinin-based combination therapies.

Maternal factors in the etiology of fetal malnutrition in Nigeria.

Abstract: The main objective of the study was to determine the role of maternal factors in the etiology of fetal malnutrition (FM) in Nigeria. Neonatal and Maternity Units of the Wesley Guild Hospital Ilesa Nigeria a unit of the Obafemi Awolowo University Teaching Hospitals Complex Ile-Ife was the setting for the study. This was a prospective study of consecutive singleton term live babies delivered between January and August 2001. Fetal malnutrition was diagnosed using Clinical Assessment of Fetal Nutritional Status (CANS) and the score (CANSCORE) adapted by Metcoff. The maternal prenatal record was checked and additional history was obtained from the mother. This included history of maternal illness and drugs taken during pregnancy. The socioeconomic class of the parents was also documented. Nutritional status of the mother was determined using mid arm circumference (MAC) and the body mass index (BMI). Babies were stratified into babies with FM and babies without FM. The two groups of babies were compared. Of the 473 studied 89 [18.8%] had FM. Maternal factors found associated with FM were: lack of antenatal care young mother (< 18 years) primiparity maternal undernutrition (BMI < 18.5 kg/m 2 and MAC < 23.5 cm) low socioeconomic status pregnancy-induced hypertension antepatum hemorrhage and maternal infections especially malaria urinary tract infections and HIV (P < 0.05). Improvement in the socioeconomic status of women and good antenatal care will reduce most of the maternal factors associated with FM in Nigeria. Therefore antenatal should be made cheap and accessible to all pregnant mothers. (authors)

Bacteriology and genotoxicity of some pharmaceutical wastewaters in Nigeria

Abstract: Wastewaters from two pharmaceutical production processes, cotrimoxazole B wastewater (BWW) and Piriton wastewater (PWW), were examined microbiologically and for physico-chemical parameters. Furthermore, the wastewaters were also screened for genotoxicity using Allium cepa assay to assess the risk associated with the discharge of untreated pharmaceutical wastewaters into the environment. The effluents induced various types of chromosomal aberrations, namely, disturbed spindle, vagrant and chromosome bridge, and also showed a dose-dependent reduction in the number of dividing cells. The mitotic inhibition ranged from 38.6 to 67.2%. The mean root length at 20% of BWW and all concentrations except 1% of PWW were significantly different from the control values (p < 0.05). The EC50 of the root growth inhibition was 4.17 and 12.45% for PWW and BWW, respectively. The wastewater physico-chemical analysis revealed that most parameters were within the allowable limits. The wastewaters had similar microbial load index of 107 cfu ml−1, indicating dense populations of bacteria, which may be due to the richness of the wastewaters in nutrients particularly sulphate, nitrate and phosphate. Coliform bacteria concentrations in the PWW and BWW wastewaters were 50MPN/100 ml and 550MPN/100 ml, respectively. The identified bacterial isolates included Staphylococcus aureus, Escherichia coli, Serratia marcescens, Klebsiella sp, Streptococcus pyogenes, Bacillus licheniformis, Yersinia sp, Proteus vulgaris and Bacillus subtilis. The resistance of the bacterial isolates ranged from 10% for gentamicin to 100% for augmentin, amoxycillin, cloxacillin and nalidixic acid. PWW isolates were more resistant. Seven patterns of multiple drug resistance ranging from 5 to 11 antibiotics were obtained amongst the isolates.

Comparative Assessment of Phytochemical Content and Antioxidant Potential of Azadirachta indica and Parquetina nigrescens Leaves

Abstract: Aim: The aim of this study is to compare the phytochemical content and antioxidant potential of Azadirachta indica and Parquetina nigrescens leaves. Study Design: This study was made to fit a one way Analysis of Variance. Place and Duration of Study: This research was carried out in Premedical Science Department, Educational Advancement Centre, Ibadan and Pharmaceutical Laboratory of the University of Ibadan, Nigeria between January and June, 2018. Methodology: Both plants were harvested from the botanical garden, University of Ibadan. The qualitative and quantitative analyses as well as antioxidant potential of both plants were investigated. Results: The result of the qualitative analysis showed that both plants contained variety of phytochemicals. The quantitative analyses showed that these phytochemicals were present in different concentrations. The concentration of phytate and total phenolics were significantly higher in A. indica when compared with those of P. nigrescens respectively at P<0.05. It was also observed that A. indica had lower concentrations in alkaloids, saponin, flavonoids and tannin when compared with those of P. nigrescens respectively. Also tested were antioxidants (ascorbic acid, DPPH and FRAP). The concentration of ascorbic acid was significantly higher in A. indica when compared with that of P. nigrescens at P<0.05. α,α-diphenyl-β-picrylhydrazyl (DPPH) radical scavenging potential of A. indica and P. nigrescens was investigated respectively at different concentrations with A. indica having the higher radical scavenging potential. The scavenging potential of DPPH was found to increase with increasing concentration of the extracts. Conclusion: Result of this study showed that both plants are rich in phytochemicals and possess antioxidant potential. Hence, they might act as prophylactic and remedy for different diseases, such as cancer, atherosclerosis, obesity, etc. Parquetina nigrescens might be more potent than Azadirachta indica in acting as a remedy for different diseases.
