T-lymphocyte subsets were studied in two patient groups: (1) 50 patients with homozygous sickle cell anaemia (SCA) (mean age 12 (range 3-32) years old) in good health at the time of the study who showed no infectious complication. (2) 50 patients (mean age 13 (range 4-29) years old) with normal haemoglobin rate. The global response revealed a significant increase in levels of CD3+ (P=0.04) and CD8+ (P=0.04) cells when compared with the control group, there was no significant difference in levels of CD4+ cells (P=0.05) between the two groups. However, there was a relationship between T-cell subpopulation levels and spleen status. The average values of T-cell subsets (CD4+ and CD8+) in patients with SCA-induced splenic defects (asplenic, splenomegaly or splenectomized patients) were significantly reduced when compared to SCA patients with normal spleens and the control groups. These data show that T-cell activity was reduced in patients with splenic defects. A correlation between splenic status and a perturbed host defence system in patients with SCA suggests that monitoring T-cell subsets might have prognostic value in the course of sickle cell disease.

Unlike developed countries, monitoring of the alimentation quality is important in developing countries. In recent years, several methods of assessing food consumption using simple tools the 24-hour diet recall have been proposed. This individual dietary diversity score (IDDS) is a simplified method for assessing the quality of diets, defined as the number of food groups represented in the diet over a period of time. We conducted an individual qualitative food consumption survey based on the 24 hours recall method. It was an Interviewer-administered questionnaire was used to collect information. The classification terciles of Dietary Diversity score was obtained from the 14 food groups recommended by FAO. 200 diabetic and 200 hypertensive patients regularly followed in the same hospital (University hospital of Treichville) were included in this study without any distinction about treatment. The average of individual dietary diversity score was to 5.6 ± 1.58 for diabetic against 6 ± 1.94 food groups consumed the day before by hypertensive. Hypertensive patients in our study seemed o better diversity their diet with 8% of them who had a high score against 0.5% for diabetic. The food groups most consumed by our population were cereals, white tubers, other vegetables, fish and oils and fats at the expense leafy vegetables, vitamin A fruits, other fruits and legumes, nuts and seeds. In terms of anthropometric factors, we found the influence of waist circumference on food diversification in diabetic and not from hypertensive. Considering the importance of dietary diversity to nutrition and health, these results show the need to mobilize efforts for ensuring that people have better access to and knowledge about adequate nutrition. Despite the fact that this study has to be performed and that comparisons with other countries are required to harmonize the methodology, our results show the interest of the use of a simple tool to assess the quality of the food within the population. Using of this tool is certainly a future solution for a rapid diagnostic of diets quality.
