The triad-iodine deficiency,hyperlipidaemia, high coronary risk— in a ‘maternal-neonate’ population of rural Africa

In order to see the pattern of changes in differential serum lipid and lipoprotein fractions as a risk marker of coronary complication in paired ‘maternal—neonate’ blood samples in an iodine deficient zone, 26 pregnant women and their corresponding new born infants at term delivery from the iodine deficient Bassa region of Plateau state, Nigeria were assessed and the results were compared with those seen in a similar 44 group of women and their newborns assessed in non lodine deficient region of Jos. The serum thyroid function and lipid and lipoprotein profiles were determined by ‘ELISA’ and ‘enzymatic’ methods respectively. Urinary iodide excretion level was also measured in 14 pregnant women in Bassa, 23 pregnant women in Jos and 16 non pregnant control from Jos. Results indicate that the pregnant women assessed in Bassa were iodine deficient (P<0.01) and their thyroid status was strikingly reduced as reflected by a drop in serum level of T4/TBG ratio (P<0.01) and a rise in TSH (P<0.005) in comparison to that seen in Jos. There was marked hypertriglyceridaemia and total hypercholesterolaemia (P<0.005), with differential significant rise in LDL cholestotol fraction (P<0.005) in the women assessed in Bassa as compared to Jos. The HDL cholesterol however dropped less significantly in the group (P<0.05) with a concurrent marked rise (P<0.001) in the serum ratio of LDL cholesterol/HDL cholesterol, total cholesterol/HDL cholesterol and triglycerides/HDL cholesterol in the lodine deficient group. A similar pattern of changes were seen in the corresponding neonates in the Bassa group as compared to Jos group. It is concluded that the pregnant women and their newborn offsprings living in a longstanding environmental iodine deficiency run a higher risk of developing coronary complications than those living in non endemic region. It is striking that such newborns surrounded by a continued state of lodine deficient may at a later adult-period of life develop marked risk of coronary complication and other features of hyperlipidaemias associated with varying thyroid insufficiency and accompanied iodine deficiency disorders. Prophylaxis measures as intervention has been highlighted.     

Evaluation of microsatellite instability in tumors of central nervous system: A pilot study

Microsatellite instability (MSI) characterized by alterations at simple repetitive genomic sequences is a distinct mechanism in tumorogenesis. Central nervous system (CNS) tumors have been reported to exhibit MSI, indicator of defective mismatch repair system with controversies. The present study was undertaken to examine sixteen primary brain and two spinal tumors for MSI at six mono: BAT-26, BAT-40, BAX, TGFßRII, IGFIIR and hMSH3 and four dinucleotide loci: D2S123, D9S1851, D9S283 and D18S58. Polymerase chain reaction (PCR) was done to amplify tumour and blood DNA, analyzed on 8% denaturing Polyacrylamide gel followed by autoradiography. Out of 18 CNS tumors examined, 39% exhibited MSI at BAT-26, BAT-40, D9S1851, D9S283 and D18S58 in tumoral DNA. However, no alteration was observed at BAX, TGFßRII, IGFIIR, hMSH3 and D2S123 loci. Low incidence of MS1-high hypothesizes role of MSI in evolution of CNS tumors but not in cancer initiation or progression.
