Consistent condom use in HIV/AIDS patients receiving antiretroviral therapy in northwestern Ethiopia: implication to reduce transmission and multiple infections.

Human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) is one of the greatest public health problems of sub-Saharan African countries. Consistent condom use, among others, remains the most effective barrier method against HIV transmission. However, existing reports on frequency of consistent condom use have targeted the general public, rather than HIV/AIDS patients due, to the assumption that condom use is not important in HIV-infected persons. Since consistent condom use among HIV/AIDS patients is vital, to prevent the virus transmission from the infected to noninfected as well as to prevent multiple infections among already infected persons, its frequency and determining factors need to be investigated.

In vivo antimalarial activity of a labdane diterpenoid from the leaves of Otostegia integrifolia Benth.

In Ethiopian traditional medicine, the leaves of Otostegia integrifolia Benth. are used for the treatment of several diseases including malaria. In an ongoing search for effective, safe and cheap antimalarial agents from plants, the 80% methanol leaf extract O. integrifolia was tested for its in vivo antimalarial activity, in a 4-day suppressive assay against Plasmodium berghei. Activity-guided fractionation of this extract which showed potent antiplasmodial activity resulted in the isolation of a labdane diterpenoid identified as otostegindiol. Otostegindiol displayed a significant (P < 0.001) antimalarial activity at doses of 25, 50 and 100 mg/kg with chemosuppression values of 50.13, 65.58 and 73.16%, respectively. Acute toxicity studies revealed that the crude extract possesses no toxicity in mice up to a maximum dose of 5000 mg/kg suggesting the relative safety of the plant when administered orally. The results of the present study indicate that otostegindiol is among the antimalarial principles in this medicinal plant, and further support claims for the traditional medicinal use of the plant for the treatment of malaria.
