[Hormone profile of hypothyroidism in an area of the Central African Republic with endemic goiter].
In the Ouham region of Centro African Republic, one of the present Authors (B.P.) described a severe goiter endemia due to marked iodine deficiency and high daily intake of manioc as staple food. In the present study serum TSH, T3 and T4 of 233 subjects were determined; 150 of them lived in rural villages (Group 1) and 83 lived in Bocaranga, chief town of the province (Group 2). The blood samples done contemporaneously to the epidemiological survey, were strictly randomized in the population examined. The subjects of each group were divided in 4 sub-groups: A) with TSH, T3 and T4 in normal range; B) with elevated TSH; C) with elevated TSH and sub-normal T4; D) with elevated TSH and sub-normal T3 and T4. An apparently euthyroid pattern of TSH, T3 and T4 was evident in only 60 subjects (19.3% from group 1; 37.35% from group 2); the remaining 173 (80.67% from group 1; 62.65% from group 2) were hypothyroid (subclinical in the sub-group B; mild in the sub-group C; overt in the sub-group D). The mean hormonal values of the apparently euthyroid subjects (sub-group A) in the villages and in the chief town, were significantly different (p less than 0.05) from the control values of our laboratory. More significant differences were clearly evident between the control values and the mean values of sub-groups B, C and D in each of the two groups (1 villages; 2 chief town).(ABSTRACT TRUNCATED AT 250 WORDS)
