Background It has been reported that people living with HIV in West Africa exhibited the highest risks for chronic kidney disease (CKD) in the world. Here, we aimed at determining the CKD frequency and changes in kidney function during antiretroviral treatment (ART) in a large cohort of HIV-patients followed in Burkina Faso. Methods We included ART-naive adults who initiated ART at the Day Care Unit of the Souro Sanou University Hospital between 01/01/2007 and 12/31/2016. We assessed the estimated glomerular filtration rate (eGFR) by serum creatinine using the Modification of Diet in Renal Disease (MDRD) equation. Following the K/DOQI recommendations, CKD was defined as eGFR < 60 ml/min/1.73m 2 at two consecutive measurements at least 3 months apart. The factors associated with eGFR decline or CKD were identified by mixed linear regression and Cox regression, respectively. Results Three thousand, one hundred and thirty-eight patients (72% women) were followed for a median (IQR) of 4.5(2.2–6.9) years. At baseline, median eGFR (IQR) was 110.7(94.4–128.4) ml/min/1.73m 2 and 93 (3%) patients exhibited eGFR < 60 ml/min/1.73m 2 . The lowest-performing progressions of eGFR during the first year of ART were observed in patients with 40-49 yr. age range (− 8.3[− 11.7;-5.0] ml/min/1.73m 2 , p < 0.001), age ≥ 50 yr. (− 6.2[− 10.7;-1.8] ml/min/1.73m 2 , p = 0.006) and high blood pressure (HBP) (− 28.4[− 46.9;-9.9] ml/min/1.73m 2 , p = 0.003) at ART initiation. Regarding the ART exposure in patients with normal baseline eGFR, zidovudine (AZT) with protease inhibitor (PI) (− 4.7[− 7.7;-1.6] ml/min/1.73m 2 , p = 0.002), tenofovir (TDF) + PI (− 13.1[− 17.4;-8.7] ml/min/1.73m 2 , p < 0.001), TDF without PI (− 3.2[− 5.0;-1.4] ml/min/1.73m 2 , p < 0.001), stavudine (d4T) + PI (− 8.5[− 14.6–2.4] ml/min/1.73m 2 , p = 0.006) and d4T without PI (− 5.0[− 7.6–2.4] ml/min/1.73m 2 , p < 0.001) were associated with poorer eGFR progression. The prevalence of CKD was 0.5% and the incidence was 1.9 [1.3; 2.7] cases/1000 person-years. The risk of CKD was higher in patients with HBP (4.3[1.8;9.9], p = 0.001), 40-49 yr. patients (4.2[1.6;11.2], p = 0.004), ≥50 yr. patients (4.5[1.5;14.1], p = 0.009) and patients exposed to abacavir (ABC) or didanosine (ddI) based ART (13.1[4.0;42.9], p < 0.001). Conclusions Our findings do not confirm...
Context:The persistent increase in the number of antibiotic-resistant strains of microorganisms has led to the development of more potent but also more expensive antibiotics. In most developing countries of the world these antibiotics are not readily affordable, thus making compliance difficult. This calls for research into alternative sources of antimicrobials. Dialium guineense is a shrub of the family Leguminosae. Its stem bark is used for the treatment of cough, toothache, and bronchitis.Aims:Despite the acclaimed efficacy of D guineense, there is no scientific evidence in its support. This work was carried out to assess the antimicrobial activity of D guineense in vitro against some clinical isolates.Materials and Methods:D guineense stem bark was collected and 50 gm of air-dried and powdered stem bark of the plant was soaked for 72 hours in 1 l of each of the six solvents used in this study. Each mixture was refluxed, agitated at 200 rpm for 1 hour, filtered using Whatman No. 1 filter paper and, finally, freeze dried. The extracts were then tested for antimicrobial activity using the agar diffusion method.Results:The highest percentage yield of 23.2% was obtained with ethanol. Phytochemical screening showed that D guineense contains anthraquinone, alkaloids, flavonoids, tannins, and saponins. The antimicrobial activity of the extracts revealed a broad spectrum of activity, with Salmonella typhi and Staphylococcus aureusa showing the greatest zones of inhibition (18.0 mm). Only Candida albicans among the fungi tested was inhibited by the extract. The greatest zone of inhibition among the fractions was 16.0 mm. D guineense exhibited bactericidal activity at the 7th and 9th hours against Streptococcus pneumoniae and S. aureus 25923 while the 10th hour against S. typhi and C. albicans. The greatest activity was noted against S pneumoniae, where there was reduced viable cell count after 6 hours of exposure.Conclusion:Stem bark extract of D guineense (Wild.) has the potential to be developed into an antimicrobial agent
Background: Holarrhena floribunda is a plant of wide usage in the Togolese folk medicine. A previous ethnobotanical survey on the latex plants of the Maritime region of the country revealed that this plant was included in several recipes curing malaria and microbial infections. Therefore, this study aimed to seek for the effectiveness of the ethanolic extract of the plant in the treatment of these diseases. Methods: The antimicrobial test was performed using the agar well-diffusion and the NCCLS broth microdilution methods, while the in vivo antimalarial activity was evaluated following the four-day suppressive test of Peters. The acute toxic effects of the extract were monitored after a single oral dose (5,000 mg/kg body weight) administration in NMRI mice. Results:The results indicated that the ethanolic extract of leaves of H. floribunda was active on Staphylococcus aureus ATCC 29213 and clinical strains of Staphylococcus aureus, Salmonella typhi and Klebsiella pneumoniae with MICs ranging from 0.62 to 1.25 mg/mL. The extract also showed significant parasitaemia suppression in a dose-dependent manner. In the acute toxicity assay, the oral administration of the extract to the mice did not affect the relative weight of vital organs, and there were no signs of toxicity or death during the study period. The LD 50 of the tested extract was found to be greater than 5,000 mg/kg, indicating its safety. Conclusion: This study demonstrates the antibacterial and antimalarial activities of leaves of H. floribunda and then, supports its medicinal use in the treatment of microbial infections.Key words: Holarrhena floribunda, ethanolic extract, antibacterial, antimalarial, toxicity. IntroductionHolarrhena floribunda (G. Don) T. Durand and Schinz, is a plant belonging to the family of Apocynaceae. It grows as a shrub or a tree. The plant is widely distributed in West Africa, where several parts of the plant are used for medicinal purposes (Yemoa et al., 2015). The stem-bark and leaves are used to treat various diseases including malaria, fever, dysentery, amoebic diseases, diarrhoea, sterility, amenorrhea and diabetes (Bouquet & Debray, 1974;Kerharo & Adam, 1974;Arbonnier, 2000;Fotie et al., 2006;Bayala et al., 2006). The roots are boiled in milk and used to bathe boys attaining puberty in addition to cure snakebites and venereal diseases (Iwu, 2014). In our previous study on the latex plant used in the maritime region of Togo, we found that the decoction of the plant was administrated by oral route for the treatment of malaria and bacterial infections (Hoekou et al., 2016).Some previous pharmacological screenings showed that, the stem bark of H. floribunda was febrifuge and could be a quinine substitute, since it showed remarkable inhibitory activity against drug-resistant strains of Plasmodium falciparum. The chemical screening of the plant revealed the presence of steroid alkaloids notably conessine, that is used for the destruction of amoeba without emetic effects (Berhaut, 1971;Fotie et al., 2006). The antioxida...
The dichloromethane/methanol leaf extract of Cassia alata had a good to moderate in vitro and in vivo antiplasmodial activity and was found to have low toxicity at high doses in tested animals.
This study aimed to list the medicinal plants used as an appetite suppressant in Hauts-Bassins areas of Burkina Faso. An ethnobotanical survey was undertaken from September to November 2021 using a semi-structured questionnaire. To determine well-known families and species, some indices such as Family Importance Value (FIV) and Relative Frequency of Citation (RFC) were calculated respectively. Sixty-seven traditional healers (41 men and 26 women) have been interviewed. The age group from 41 to 60 years old was more represented (47.76%). Fifty-eight (58) plant species belonging to 29 families and 53 genera were recorded to have appetite suppressant properties. Fabaceae family (25%) was the most mentioned followed by Combretaceae (12%). The most mentioned species were Guierasenegalensis (7.64%), Parkiabiglobosa (6.18%), Annona senegalensis and Gardenia erubescens (5.35% for both). Leaves and fruits had the highest frequencies of use with 41% and 25% respectively. The decoction (49.62%) was the main preparation method. The oral route was the only mode of drug administration. These results would contribute to strengthening the database on the medicinal plants used as an appetite suppressant by the traditional healers in Burkina Faso.
Cotton farmers are exposed to a variety of pesticide formulations, some of which contain active endocrine disrupting substances. The objective of this study was to investigate the link between pesticide exposure and thyroid disorders in cotton growers. This was a longitudinal prospective study among cotton producers during and after the 2018/2019 cotton season in the Satiri department. Surveys have been conducted on a cohort of 50 producers to collect socio-demographic and professional information on the producers and the pesticides used. A medical examination of the producers followed by blood samples were carried out during and after the cotton season. The thyroid stimulating hormone (TSH), Free tetra- iodo-thyronine (FT4) and Free tri-iodo-thyronine (FT3) biomarkers were measured on the Cobas®6000 automaton. During the cotton campaign, an overall frequency of 12.00% of dysthyroidism, of which 8.00% of hypothyroidism and 4.00% of hyperthyroidism were recorded. After the campaign, 14.00% dysthyroidism was observed, including 8.00% of hypothyroidism and 6.00% of hyperthyroidism. Also, a significant decrease in TSH concentrations; a significant increase in FT4 and a non-significant decrease in FT3 were observed. This study does not establish a specific link between exposure to pesticides and thyroid disorders due to the complexity and cocktail effect of pesticides. Rational use of these products is essential to avoid health effects linked to endocrine disruption.
Introduction:The main objective of this study was to investigate abnormalities of serum protein fractions in hemodialysis patients with chronic renal failure (CRF) in Ouagadougou, Burkina Faso. Methods: This was a descriptive cross-sectional study of 48 hemodialysis patients with chronic renal failure (CRF) recruited at the Yalgado Ouedraogo Teaching Hospital (YO-TH), and 48 controls declared fit to donate blood by the Regional Blood Transfusion Center (RBTC) of Ouagadougou. Urea, creatinine, uric acid, and serum proteins were measured on the ARCHITECT C4000 equipment (ABOTT ® ), while the separating of the different protein fractions was performed on the Helena SAS 3 & 4 automated system. Results: A total of 96 individuals were included in the study. Protein levels were on average higher in controls (75.19 ± 6.56 g/L) than in hemodialysis patients (71.44 ± 12.33 g/L). Low blood albumin was significantly associated with the CRF hemodialysis groups compared to controls (p < 0.000). In terms of globin fractions, a significant increase in alpha-globulin 1, alpha-globulin 2 and gamma-globulin was present in the CRF hemodialysis group compared to controls (p < 0.000); while beta-globulin was on average lower in the CRF hemodialysis group compared to controls without significant difference (p = 0.509). Analysis of the electrophoretic profiles identified 57.17% polyclonal hypergammaglobulinaemia, 33.33% inflammatory profile, 10.42% undernutrition profile and 2.08% nephrotic syndrome in the CRF hemodialysis group. Conclusion: Serum protein electrophoresis is rapidly feasible and low cost. In hemodialysis CKD patients, it can be used to guide therapeutic management and predict morbidity and mortality related to variations in the various protein fractions.
