Item Chronic Alcohol Consumption Affects Serum Enzymes Levels in the HIV-Infected Patients on Stavudine (d4T)/Lamivudine (3TC)/Nevirapine (NVP) Treatment Regimen(Pharmacology & Pharmacy, 2014) Bbosa, Godfrey S.; Kyegombe, David B.; Anokbonggo, William W.; Lubega, Aloysius; Mugisha, Apollo; Ogwal-Okeng, JasperChronic alcohol use is a common problem globally among the HIV-infected patients on ARV treatment regimens, leading to severe liver damage and increase in serum enzymes. The study determined effect of chronic alcohol intake on serum enzymes (alanine aminotransferase (ALT), aspartate aminotransferase (AST) and γ-glutamyl transferase (GGT)) in HIV-infected patients on d4T/3TC/NVP treatment regimen in Uganda using the WHO alcohol use disorders’ identification test (AUDIT) tool and chronic alcohol use biomarkers (ALT, AST, GGT, AST/ALT ≥ 2.0 and mean corpuscular volume (MCV)). A case control study using repeated measure design with serial measurements model was used. Alcohol use biomarkers were used to standardize the gender differences in alcohol use. A total of 41 patients (21 alcohol group and 20 control group) were followed up for 9 months with blood sampling done at 3 month intervals. The serum enzymes’ levels were determined by using the Cobas In-tergra 400 Plus analyzer system. The mean GGT levels were higher in chronic alcohol use group as compared to control group in both groups. The levels were above reference ranges during 6 month and three times higher during 9-month follow-up period for both chronic alcohol use self reporting WHO AUDIT tool and biomarkers’ groups. Generally, the mean AST, ALT and AST/ALT levels were slightly higher in alcohol use group as com-pared to control group and were slightly higher in both groups as compared to reference ranges during the 9 month follow-up period. Chronic alcohol consumption by HIV-infected patients on d4T/3TC/NVP drug regimen increased GGT and AST/ALT serum enzyme levels and hence was used as chronic alcohol use biomarkers.Item Chronic alcohol use affects therapeutic steady state plasma drug concentrations of stavudine, lamivudine and nevirapine in HIV-infected patients during 9 months follow up period: WHO AUDIT tool application(International Journal of Basic & Clinical Pharmacology, 2013) Bbosa, Godfrey S.; Kyegombe, David B.; Anokbonggo, William W.; Ntale, Muhammad; Musoke, David; Odda, John; Lubega, Aloysius; Ogwal-Okeng, JasperChronic alcohol consumption is a common problem among the HIV-infected patients on HAART. The study determined the effect of chronic alcohol use on steady state plasma drug concentrations of stavudine (d4T), lamivudine (3TC) and nevirapine (NVP) in HIV-infected patients during the 9 months follow up period. It also determined whether there were some patients with undetectable plasma drug concentrations in their plasma during the follow up. A case control using repeated measures design with serial measurements model, where plasma drug concentrations were measured at 3 month intervals was used. Chronic alcohol-use using WHO AUDIT tool was used to screen patients. A total of 41 patients (21 alcohol group and 20 control group) were followed up for 9 months with blood sampling done at 3 month intervals. The Shimadzu Class-VPTM HPLC Chromatography data system version 6.1 equipment with UV detector was used to measure the plasma drug concentrations. Data was analyzed using SAS 2003 version 9.1 statistical package with repeated measures fixed the model and means were compared using the student t-test. The mean steady state plasma concentration of both d4T and 3TC in chronic alcohol use group were lower than in the control group all throughout the 9 months period of follow-up. The mean steady state plasma drug concentrations of NVP were higher in the alcohol group at 0 and 3 months and lower in the 6 and 9 months as compared to the control group. The mean total plasma NVP concentration was higher in the chronic alcohol group as compared to the control group and the difference was statistically significant (p≤0.05). However some patients had undetectable plasma drug concentrations despite of having ≥ 95 % adherence rate. Chronic alcohol use by the HIV-infected patients lowers the steady state plasma drug concentrations of d4T, 3TC and NVP in patients.Item Effect of chronic alcohol consumption on the red blood cell count and RBC indices in the HIV infected patients on d4T/3TC/NVP drug regimen in Uganda(IJBCP International Journal of Basic & Clinical Pharmacology, 2013) Bbosa, Godfrey S.; Kyegombe, David B.; Anokbonggo, William W.; Lubega, Aloysius; Mugisha, Apollo; Ogwal-Okeng, JasperAlcohol consumption is common problem in Uganda. Among the types of alcohols consumed include beers, spirits, liqueurs, wines and traditional brew. These alcohols are easily accessible and consumed by many people including the HIV infected patients who are on the d4T/3TC/NVP regimen. The aim of this study was to determine the effect of chronic alcohol intake on the red blood cell count (RBC) and the RBC indices in the HIV-infected patients on d4T/3TC/NVP regimen. It was a case control study that used a repeated measures design model where serial measurements of the red blood cell count (RBC) and RBC indices were determined at 3 month interval for 9 months. A total of 41 HIV infected patients were recruited and grouped into two arms; the control group had 21 patients and the chronic alcohol group had 20 patients. The RBC and RBC indices of the whole blood were determined using automated hematological Coulter CBC-5 Hematology Analyzer system using standard procedures. The data was sorted into alcohol-use self reporting by WHO AUDIT tool and alcohol-use biomarkers groups. It was analysed using the SAS 2003 version 9.1 statistical package with the repeated measures fixed model. The means were compared using the student t-test. The mean MCV and MCH values in the chronic alcohol use group were higher than in the control group and there was a significant difference between the 2 groups (p<0.05) for both the WHO AUDIT tool group and chronic alcohol use biomarkers group. The mean RBC count, Hct, HGB and MCHC values in both the control and chronic alcohol use groups were within the normal reference ranges for both groups though the trend was lower in alcohol group. Chronic alcohol use affects the RBC and RBC indices in the HIV infected patients on d4T/3TC/NVP treatment regimen.Item Medicinal plants used by traditional medicine practitioners for the treatment of HIV/AIDS and related conditions in Uganda(Journal of ethnopharmacology, 2010) Lamorde, Mohammed; Tabuti, John R.S.; Obua, Celestino; Kukunda-Byobona, Collins; Lanyero, Hindam; Byakika-Kibwika, Pauline; Bbosa, Godfrey S.; Lubega, Aloysius; Ogwal-Okeng, Jasper; Ryan, Mairin; Waako, Paul J.; Merry, ConceptaIn Uganda, there are over one million people with HIV/AIDS. When advanced, this disease is characterized by life-threatening opportunistic infections. As the formal health sector struggles to confront this epidemic, new medicines from traditional sources are needed to complement control efforts. This study was conducted to document herbal medicines used in the treatment of HIV/AIDS and related opportunistic infections, and to document the existing knowledge, attitudes and practices related to HIV/AIDS recognition, control and treatment in Sembabule, Kamuli, Kabale and Gulu districts in Uganda.Item Uterotonic Potential of Selected Plants Used by Ugandan Local Communities in the Treatment of Malaria(European Journal of Medicinal Plants, 2018) Katuura, Esther; Kalabika, Enock; Lubega, AloysiusMalaria is a major cause of death among pregnant women and children under the age of five in Uganda. It is the leading cause of anemia among pregnant women and low birth weight in infants [1]. Majority of the rural population rely on herbs for treatment of various diseases. The leaf extracts of various plants including Bothlioclines longipes, Vernonia amygdalina, Rhus natalensis and Maesa lanceolata are used to treat various diseases including malaria in Uganda. The local communities prefer herbal preparations from the leaves of the plants. Extracts from the leaves of the plants were proven efficacious against P. falciparum in earlier studies in vitro. This study was carried out to investigate the effect of Diethyl ether and methanol extracts on the contractility of an isolated rabbit uterus and also to quantitatively analyze for iron and zinc in the leaves of these plants. The diethyl ether extracts of V. amygdalina, M. lanceolata and R. natalensis at a concentration of 0.4 mg/ml and 0.8 mg/ml exhibitedcontractility amplitudes of 26.0 mm, 21.5 mm and 27.5 mm and 22.5±1.10 mm, 15.0±1.78 mm and 24.5 ±0.99 mm respectively. The methanol extracts were 25.5±0.70 mm, 23±1.34 mm, 22±1.01 mm and 37.8±1.26 mm, 16.7±2.01 mm, 24.3±0.06 mm respectively, while oxytocin showed 22.8±0.57 mm and 31.0±0.36 mm respectively. The plant leaves were found to have high levels of iron ranging from 2516.587±17.983 (mg/100 g) in B. longipes to 583.317±9.505 (mg/100 g) in V. amygdalina. Rhus natalensis and V. amygdalina had low levels of Zinc. Anti-nutritive phytocompounds such as saponins and Tannins were also detected in some of the test extracts. The study concludes that plants used by pregnant women may have either a positive or negative effect on expectant mothers. There is need to formulate evidence based effective medicines for their safe use in the management of malaria.
