Failure of a new antivenom to treat Echis ocellatus snake bite in rural Ghana: the importance of quality surveillance.

This study compares two antivenoms used to treat Echis ocellatus snake bite patients at Mathias Hospital, Yeji, central Ghana. FAV-Afrique antivenom (Aventis Pasteur) was given to 278 patients during 2001--2003, whilst Asna Antivenom C (Bharat Serum and Vaccines Ltd) was used in 2004 to treat 66 patients. The two groups had comparable patient attributes, time from snake bite to treatment and staff adherence to the tested treatment protocol. The antivenom C group required more repeat doses and twice the amount of antivenom to treat coagulopathy. Of greater concern, the antivenom C mortality rate was 12.1%, a marked rise from the 1.8% rate in the earlier FAV-Afrique antivenom group. In this study, antivenom C was ineffective as treatment for West African E. ocellatus snake venom. This illustrates the absolute need for regional pilot tests to assess the effectiveness of a new antivenom against local snake venoms before its sole and general distribution in a region is initiated.

Infertility in rural Ghana.

OBJECTIVES: This study measured the prevalence of self-reported infertility, as well as the level of knowledge of causes of infertility. Infertility was defined as failure to achieve conception after a minimum of 12 months of exposure. METHODS: Prevalence and knowledge of infertility were assessed in a representative community-based survey using a structured questionnaire in a rural district in Ghana among a random sample of 2,179 men and women from 15 to 49 years. RESULTS: The prevalence of infertility was 11.8% among women and 15.8% among men. The knowledge of causes of infertility was limited; only 46.5% of the respondents reported any cause. Most respondents failed to identify reproductive tract infections as causes of infertility. CONCLUSIONS: Infertility in Ghana and other sub-Saharan countries deserves more recognition as a public health problem. Prevention and treatment of infertility should be incorporated in reproductive health programs, while male participation in reproductive health programs and research needs to be encouraged. Public education about the causes of infertility is recommended.

Malaria prophylaxis and the reduction of anemia at childbirth.

OBJECTIVES: To assess the effect of introducing chloroquine prophylaxis during pregnancy on prevalence of anemia (<10.9 g/dl) at childbirth and perinatal outcome. METHODS: Observational study in a rural district hospital in Ghana, which compared 2803 women who received chloroquine prophylaxis during pregnancy with 3084 historical controls, who had not received prophylaxis during pregnancy. Main outcome measures were hemoglobin level at childbirth, perinatal mortality and birth weight. RESULTS: Mean hemoglobin level before childbirth increased from 10.7 g/dl (S.D.=1.0 g/dl) to 11.0 g/dl (S.D.=0.9 g/dl). Prevalence of anemia decreased from 29.4 to 13.3% (OR=0.4 and 95% CI=0.3-0.4). Prevalence of moderately severe anemia (<9.0 g/dl) decreased from 4.4 to 3.3% (OR=0.7, 95% CI=0.6-0.97). Perinatal mortality and low birth weight (<2500 g) remained unchanged. CONCLUSIONS: Routine chloroquine prophylaxis in pregnancy is useful in reducing anemia at childbirth in malaria-endemic regions. Fetal outcome did not improve with chloroquine prophylaxis in this study.

Contraception and induced abortion in rural Ghana.

This article describes the results of a community-based survey on birth control in a rural district in western Ghana. Structured interviews with 2179 women and men aged 15-49 years were used to study the prevalence of contraceptive methods and induced abortion. In addition, the influence of induced abortion on reported fertility in relation to residence and education was analysed. The results show that 59.8% had used a contraceptive method at some time in life, while use of induced abortion was reported by 22.6% of respondents. Prevalence of ever-use of any method to avoid childbirth, contraception and/or induced abortion was 67.1%. Urban residence and higher education were associated with more induced abortions and higher use of contraceptive methods. Differences in use of induced abortion were partly responsible for the education and residence-related changes in fertility. Induced abortion needs to be considered when discussing methods in use to avoid childbirth in developing countries.
