[Modification of hemorheological parameters in microvascular complications of diabetes].

The aim of the present study was to assess the possible modifications in the parameters of red cell aggregation and blood and plasma viscosity in 92 diabetic patients compared to 82 non diabetic control subjects. Based on the presence of microalbuminuria (> 30 mg/24 h) and/or retinopathy each group of diabetic patients was divided into two subgroups. This study shows increased red cell aggregation and blood viscosity among diabetic patients with microangiopathy. There was a very good correlation between fibrinogen level and the different rheological measurements. The results of this study confirm the importance of the blood rheology abnormalities observable in diabetes. These disorders increase peripheral vascular resistances and ischemia and therefore worsen diabetic nephropathy and retinopathy.

Reliability of glucose measurement by glucose test strips in tropical conditions.

The reliability of glucose test strips and reflectance meters after storage in tropical conditions was assessed. In a first experiment, sealed bottles containing glucose test strips were stored for 1 month in closed sterilising ovens at 40 degrees C, one in dry (0% humidity) and the other in wet (75% humidity) conditions. Results were compared to measurements obtained with glucose test strips stored under standard Western conditions, in non-diabetic and diabetic patients, using the same standard reflectance meter. A second experiment was performed similarly, comparing the values obtained with reflectance meters stored in different conditions, using standard glucose test strips. Reproducibility was assessed on the basis of duplicate measurements for each condition of storage. We observed that temperature and humidity did not significantly affect the glucose test strips (1st experiment), while a slight underestimation of capillary blood glucose was found using reflectance meters stored at 50 degrees C, irrespective of the humidity (2nd experiment). All the correlation coefficients between duplicates were greater than 0.975 irrespective of the conditions of storage for glucose test strips and reflectance meters. Therefore, glucose test strips and reflectance meters appear fairly reliable at the grass-root level in the tropics, if used carefully.

[The nutritional immunodeficiency syndrome].

There is a strong relationship between nutritional status and resistance to infection. This relationship must receive attention more especially as human being is young. Newborns and infants have some immunological immaturity in regard to systemic immunity as well as local (particularly intestinal), immune defense. Malnutrition is an aggravating factor vis a vis such an immunodeficiency. It modifies the regulating activities of the different lymphocyte populations, of the macrophages, of the complementary system. These disorders are bound to energy, proteins, vitamins and mineral deficiencies. But many metabolic phenomenons have still to be explored, as well as the effect of such a dysimmunity on immunization. Bowel epithelial cells, cross-roads between immunity and nutrition, seem to be the point we ought to select in order to dislocate the infection--malnutrition couple.

[Survey of nutritional pathology in Mauritania].

A display of the different nutritional problems in Mauritania, such as they could be studied under the working medical conditions in this country. This study shows the coexistence, into a low life level country, of nutritional deficiency diseases, and obesity induced diseases, especially frequent among the mature women. This reality emphasizes the complexity of the mechanisms responsible for the nutritional diseases, and advocates for a global action to improve the nutritional status of a population. This supposes to integrate all the known data, including social and cultural knowledges.

[Tropical diabetes mellitus, a new nutritional indicator?].

Studies on diabetes mellitus in tropical zones indicate that its traditional link with overnutrition depends not only on the economic level, but also on some ethnic, social and cultural factors. At present, we insist on the unexpected relationship between diabetes mellitus and undernutrition either in some major infantile forms (described in India and Nigeria) with calcareous pancreatitis, or some less severe forms observed in Africa. This tropical diabetes mellitus occurs in some patients with normal weight or inferior to normal; it is not very ketogenic, responding to glucagon stimulation, and seems more frequent in the chronic malnutrition areas. So, it is tempting to utilize diabetes mellitus as an indicator of nutritional disorder or of dietary toxic factors. However, we ought to consider it within a multifactor surroundings associating genetic determinism and the other factors of tropical aggressiveness.
