BackgroundLow concentration of trace elements has been associated with poor prognosis and mortality in HIV infection.MethodsA cross sectional study was conducted among 100 HIV-infected subjects (70 were on ART treatment, while 30 were ART naïve). Fifty (50) apparently healthy controls were enrolled. Concentration of serum levels of zinc and copper was done using atomic absorption spectrometric method, while complete blood count was determined using automated blood analyzer. CD4+ T-cell count was done using cyflow cytometer.Aim and settingThe aim of this study was to investigate the level of some trace elements and some hematological parameters of HIV-seropositive subjects attending University of Calabar Teaching Hospital Clinic as well as prevalence of trace elements deficiency and anemic status and compare same with HIV-seronegative control.ResultsMean serum zinc, CD4+ T-cell count, Hb, PCV, RBC, MXD, were significantly (p < 0.05) reduced in the HIV-infected subjects, while copper/zinc ratio, MCV, MCH and platelet count were significantly (p < 0.05) raised in the HIV-infected subjects. The serum Cu level was comparable (p > 0.05) with the control. ART treatment had no effect on all the parameters assessed except CD4+ T-cell count. Twenty five percent (25%), 3% and 56% of the HIV-infected subjects were zinc deficient, copper deficient and anemic, respectively. Gender was found as a predictor of zinc deficiency. Copper and zinc showed weak positive correlation with CD4+ T-cell count.ConclusionART treatment did not complement zinc status in HIV infection while improving CD4+ T-cell count, hence the need to consider supplementation.
BackgroundThe use of plants and plant products for medicinal purposes is an age-long practice in traditional communities and is becoming prominent globally. This study was performed to evaluate the effect of ethanolic extract of Chromolaena odorata on the kidney and intestine of albino rats.MethodsTwenty growing albino rats with an average weight of 54 g were used in this study. They were grouped into four groups. Groups 1, 2, and 3, known as the test groups, were given 50 mg/kg, 100 mg/kg, and 250 mg/kg ethanolic extract of C. odorata, respectively, while the control group was given distilled water orally. The experiment was performed for 6 weeks. The animals were killed using chloroform suffocation. The kidneys and the intestine were harvested and fixed in 10% neutral buffered formalin for histological analysis. Blood samples were collected from the animals by heart puncture for estimation of creatinine and urea levels.ResultsThe creatinine, urea, aspartate aminotransferase, alanine transaminase, and alkaline phosphatase levels of blood sample from the test group were significantly different when compared with the control (p < 0.05). The histological sections of the kidneys in this study showed no signs of degeneration. Infiltration of inflammatory cells and epithelial erosion were observed in the histology sections of the intestine of all the test groups.ConclusionThe results from this study revealed that uncontrolled use of this plant extract has an adverse effect on the kidney function and on the histology of the intestine of the rats used in this study.
Background: Collection of data concerning men's health generally and urological health particularly has always had its challenges, especially in the African setting. Some of the difficulties stem from cultural factors that consider sensitive topics pertaining to men's health as taboo. Aim: To determine how to overcome barriers in conducting a transatlantic prostate cancer familial study in Africans. Methods: After the first phase of the TRANSATLANTIC PROSTATE CANCER FAMILIAL PROJECT STUDY, a survey was carried out among the data collectors and principal investigators using Qualtrix software to collect qualitative feedback on the study. The data from the survey was analyzed using SPSS version 18. Results: Presently, 625 people are enrolled for the study and more are waiting to be recruited in the next phase. About 73% of the participants requested a home or office visit rather than visit a data collection center. On the average, the questionnaire required an average of two hours of personal interview rather than the one hour that had been envisaged. However the participants declared that participant incentives were well worth it. 80% of the participants had no preference for interviewer gender. 80% of the interviewers agreed that answers to questions about participants' sexuality were most difficult to obtain but with an in-depth explanation of the importance of the study and assurance of privacy, the answers were obtained. About 46% of the participants requested that their results be typed and given to them personally, 21% requested results be sent as to them as text messages while 26% requested general results of the study be made available to them in form of booklets, flyers and orally in town hall meetings. Conclusion: The TRANSATLANTIC PROSTATE CANCER FAMILIAL PROJECT STUDY survey questionnaire is a very workable tool that has a high acceptance rate among participants. The best practice for engaging the community for research include community mobilization through sensitization visits and one-on-one talks, use of community 'gatekeepers', introduction by relatives, assurance of privacy of health data obtained, the use of incentives and a promise to give feedback on the results of the study both on a personal and community level.
Background Hypoestes rosea (family: Acanthacea ), has been harnessed and utilized for treatment of several ailments. However, there is the paucity of available data on nephrotoxicity associated with this herb. Here, we investigated the phytochemical profile and toxicological effect of H. rosea on Wistar Rats. Methods Twenty rats (weight range: 75–100 g) were assigned into five study groups, viz; (a) control (without treatment) (b) treatment group 1, orally administered with 50 mg/kg (c) treatment group 2, orally administered with 100 mg/kg (d) treatment group 3, orally administered with 250 mg/kg, and (e) treatment group 4, orally administered with 300 mg/kg of H. rosea, respectively for 28 days of four rats per group. The rats were made unconscious by using oral administration of chloroform. Cardiac punctures were made, and blood samples collected into 10 ml labeled plain container, allowed to clot and spun to harvest serum for determination of sodium, potassium, chloride, bicarbonate, urea and creatinine using colorimetric, back-titrimetric, Urease-Berthelot and Jaffe’s reaction methods respectively. Kidneys of rats were harvested, weighed and immediately fixed in 10% neutral buffered formalin for histological analysis. Result Mean serum sodium (p = 0.049), potassium (p = 0.007), and urea (p < 0.001) levels were significantly higher among the treatment groups compared to controls. Histopathological findings of kidney sections revealed mild glomerular infiltration in treatment groups 2–4. Additionally, sclerosis was observed in groups 3–4. Phytochemical analysis of H. rosea revealed presence of alkaloids, flavonoids, saponins, tannins, terpenoids, steroids and reducing sugars. Conclusion From the findings in this study, H. rosea leaf extract causes significant damage to the kidneys of Wistar rats at higher doses. Of which, the damages were dose-dependent in direct proportionality manner. To better determine the safe dosage and ideal duration of consumption, there is the need for further studies on H. rosea.
Introduction: Although viremia has been greatly addressed in the management of human immunodeficiency virus (HIV) infection by the advancement in antiretroviral therapy, not all HIV-associated morbidities have been resolved. Observations of increased cardiovascular risk in relation to antiretroviral therapy have been reported. Full blood count continues to be useful in disease management, and efforts are directed towards optimising its utility in medical practice. Derivatives of blood cell counts have in recent times proved to be informative with regards to the inflammatory-thrombotic cycle. The utility of these derived parameters in HIV within the study locality is worth exploring. Methods: This single-site study was carried out at University of Calabar Teaching Hospital in Calabar, Cross River State of Nigeria. White blood cell and platelet counts were carried out by automation, while blood cell ratios were calculated. Statistical analysis of data was done using SPSS 22.0. A p-value of ≤ 0.05 was considered to infer a statistically significant difference. Results: Significant reductions of white blood cell parameters were recorded in HIV, particularly among infected persons on antiretroviral therapy. Platelet count and plateletcrit were significantly lower, while mean platelet volume and platelet distribution width were higher in newly diagnosed persons compared to HIV-infected subjects on therapy and control subjects. Platelet-to-lymphocyte ratio was significantly higher among subjects on therapy compared to the rest of the groups. Conclusion: Increase in platelet count following antiretroviral therapy could be posing a risk of platelet-driven morbidities as typified in the observed elevated thrombotic marker.
