Abstract

Eleven selected prostitute leaders were recruited who subsequently recruited 157 of their peers, bringing the total to 168. Sera was collected and tested for antibodies to HIV-1 and HIV-2 using a commercial enzyme-linked immunoabsorbent assay (ELISA); positive cases were confirmed by Western Blot (Dupont). A direct immunofluorescent method was performed on smears from the endocervical junction. Twelve of 168 (7.1%) of the women tested were found to be HIV-1 positive; none were found positive for HIV-2. Sixty six of 168 (38.3%) were found to be Chlamydia trachomatis (CT) positive; three cases (1.8%) were found to be positive for both HIV-1 and CT. Prostitutes are a high risk group in Yaoundé for HIV and chlamydia infections. The results in this study may not reflect the seriousness of the situation given the selected population used. Similar studies still need to be carried out. Prostitutes need to be educated about AIDS, other STDs and the use of condoms to protect their clients and themselves. [ABSTRACT FROM PUBLISHER]

Abstract

This work studies the relationship between a common genetic marker in our population, sickle-cell trait, and atherogenic risk factors. One hundred and twenty-two healthy subjects were studied. Forty-six subjects had normal haemoglobin (HB-AA) while 76 had sickle-cell trait Hb-AS. Mean cholesterol level was higher in subjects with sickle-cell trait (2.82 +/- 0.21 g/I) than in subjects with normal haemoglobin (2.08 +/- 0.40 g/I) used as controls. The difference was statistically significant (p < 0.05). HDL cholesterol levels remained in the normal range in controls (Hb-AA) (0.560 +/- 0.10 g/I) while subjects with Hb-AS had high HDL-c levels (0.618 +/- 0.30 g/I). Mean LDL cholesterol levels in Hb-AS subjects were about 57% higher than those in controls (1.84 +/- 0.10 g/I and 1.17 +/- 0.30 g/I, respectively) (p < 0.05). Apolipoprotein A1 levels of Hb-AS subjects were lower (1.37 +/- 0.10 g) than those of Hb-AA subjects (1.98 +/- 0.15 g/I), (p < 0.05) while apolipoprotein B concentrations of Hb-AS subjects were higher (1.70 +/- 0.27 g/I) than in controls (1.30 +/- 0.10 g/I) (p < 0.05). The atherogenicity index given by the Apo-B/Apo-AI ratio was higher in Hb-AS subjects (1.24) than in those with normal haemoglobin (0.65). We conclude that Hb-AS subjects are at high atherogenic risk if subsequent diet management is not undertaken.

Abstract

Total serum cholesterol and lipoproteins levels were determined in a selected group of healthy and Plasmodium falciparum infected Cameroonians. There was a significant difference (P less than 0.05) in the level of the cholesterol between normal individuals (1.61 +/- 0.60 g1-1) and patients (1.23 +/- 0.37 g1-1). The mean values +/- SD of HDL cholesterol were (0.62 +/- 0.25 g1-1) and (0.46 +/- 0.36 g1-1) for controls and malaria infected subjects respectively. The LDL cholesterol concentration was (0.77 +/- 0.85 g1-1) in patients compared to (0.99 +/- 0.33 g1-1) for controls. There was a significant difference between the apolipoprotein B concentration in the sera of non infected (1.03 +/- 0.50 g1-1) and infected subjects (1.64 +/- 0.50 g1-1) (P less than 0.05). A decrease of apolipoprotein A was observed in the sera of patients (1.36 +/- 0.60 g1-1) compared to controls (1.70 +/- 0.34 g1-1). These results suggest a possible atherogenic risk during persistent malaria infection.
