RESUMO
A study to evaluate the levels of interferon-gamma, interleukins 6 and 10, hepcidin, iron status and some haematological parameters in persons living with human immunodeficiency virus was carried out. A total of 150 subjects aged 18-60 years were enlisted for this study. The subjects were grouped into: Group A (50 control subjects) and Group B (100 HIV subjects, 50 subjects were non ART HIV patients, 50 subjects were on Lamivudine, Tenofavir and Efavirenz). About 7ml of venous blood were collected from each subject;4.5ml of blood were placed into plain tubes for assay of interferon gamma, interleukins (6&10), hepcidin and iron and 2.5ml for FBC, CD4 count and HIV screening. The cytokines and hepcidinwere measured using Melsin ELISA Kits and Teco Diagnostics kits used for iron. Full blood count was determined by automation using Mindray BC-5300, China. The data was analysed with the statistical package for social science (SPSS) version 20 using ANOVA and the level of significance set at P<0.05. The results showed difference that was statistically significant (P<0.05) in IFN-γ (16.25±0.87pg/ml, 29.31±1.44pg/ml,18.49±1.48pg/ml, P=0.000),IL-6(7.98±0.22pg/ml, 11.08±1.21pg/ml,8.79±0.76pg/ml,P=0.000), IL-10(8.52±0.62pg/ml, 16.62±1.53pg/ml,10.39±1.06Pg/ml P=0.000), CD4 (1045.54 ±247.24Cells/L, 195.60 ±35.94Cells/L,10.39±1.06cells/L P=0.000), hepcidin (6.03±1.38ng/ml, 39.59 ±4.50ng/ml, 20.86±3.43ng/ml, P=0.000), Iron (86.29±7.27 μg/dl, 73.43±5.45 μg/dl,85.44±8.45μg/dl, P=0.000), TIBC (345.56±28.40 μg/dl, 287.19 ±8.21μg/dl,305.46±18.82μg/dl, P=0.000),%TSA (25.16±3.18%, 25.61±2.22%,28.08 ±3.42%,P=0.000) WBC (5.87 ±0.88 X 109/L, 4.69±0.72X 109/L,4.80±0.45X 109/L, P=0.000), Neutrophils (60.57±2.83%, 75.16±3.68%,69.04±2.90%, P=0.000), Lymphocytes (30.69 ±2.84%, 17.24±2.50%, 24.46±2.60%,P=0.000), Monocytes (5.59 ±1.2%, 4.18±1.12%,3.97±0.92%, P=0.000), Eosinophils (2.30 ±1.05%, 2.16±0.82%,1.67±0.57%, P=0.000), Basophil 0.86 ±0.39%, 1.31±0.94%, 0.86±0.44%,P=0.018), RBC (4.92±0.30 X 1012/L, 3.34±0.21 X 1012/L,3.60 ±0.18X 1012/L, P=0.000), Haemoglobin (14.75±0.90,g/dl, 10.05±0.65g/dl,10.80±0.53g/dl, P=0.000), PCV (44.25±2.70%, 30.14±1.95,32.56±1.50%, P=0.000), MCV(89.92±2.3fl, 79.49±1.28fl,88.15±2.08fl, P=0.029), MCH (36.12±1.53pg, 26.60±0.48P, P=0.002), Platelets (261.75±22.71 X 109/L, 246.16±9.93 X 109/L,189.32±17.00X 109/L, P=0.000), ESR (7.03 ±1.38mm/hr, 59.52 ±6.46mm/hr,43.34±4.82mm/hr, P=0.000) when compared among Control, Non ART HIV and ART positive subjects.g,28.57±1.78pg, P=0.000), MCHC (368.46±12.28g/l, 318.92±7.33g/l,333.56±22.61g/l. The study shows that interferon gamma, interleukin 6, interleukin 10 and hepcidin are some of the biomarkers in thepathogenesis of HIV. The infection of HIV increases the levels of the cytokines. The cytokines and hepcidin can be used as prognostic and diagnostic markers as their levels decreased with treatment of the patients
RESUMO
Abnormal fluoride levels in drinking water have been associated with adverse health effects. To determine the fluoride content of well waters in Enugu, southeastern Nigeria, water samples from 50 artisan wells chosen by multistage sampling procedure from the 5 zones of Enugu municipality were analyzed in duplicates for their fluoride content. The zonal mean values were 0.60, 0.70, 0.62, 0.62, and 0.63 mg/L for Abakpa Nike, Achara Layout, Obiagu/ Ogui, Trans Ekulu and Uwani, respectively [p<0.05]. The mean value for the whole city was 0.63 mg/L. Although, the mean level of fluoride recorded in this study is currently within safe limits [1.5 mg/L, WHO 2011], it is important to monitor continuously the fluoride content of well waters in the municipality in view of the increasing industrial activities going on in the city and heavy reliance on well water for domestic purposes and the widespread use of consumer products containing fluoride
