Ferritin concentrations in low-birth babies in South-west Nigeria

In the absence of acute phase reaction, ferritin concentration has been used as a standard measurement of iron stores. Low birth weight babies are at risk of developing iron lack because ferritin concentration at birth is influenced by duration of gestation, maternal iron status and conditions altering maternal­foetal iron exchange. Aim: The aim of this study was to determine the ferritin concentrations of low birth weight babies in comparison with that of normal birth weight babies. Materials and methods: Fortyfour normal birth weight (NBW) babies and 40 low birth weight (LBW) babies were recruited for the study. About 1.0ml of venous blood was drawn aseptically from each subject into a micro EDTA tube, centrifuged at 5000rpm for 5 minutes, the plasma separated into cryotubes and stored at-20oC until ready for quantitative determination of ferritin concentrations using direct immunoenzymatic colorimetric method.Data obtained was analysed statistically using the Statistical Package for Social Sciences (SPSS,version 23, Chicago, IL, USA). Results: Gestational age correlated positively with ferritin concentrations in LBW neonates (p<0.05)while APGAR score correlatepositively with ferritin concentrations in normal birth weight babies (r=0.398; p<0.05). Thoug not statistically significant (p=0.214), median values for ferritin concentrations were 188.5µg/ dl and 373µg/dl for LBW and NBW neonates respectively. Conclusion: Gestational age correlated positively with ferritin concentrations in LBW neonates

Priapism in homozygous sickle cell patients: important clinical and laboratory associations

To evaluate the relationship between the occurrence of priapism and important steady-state clinical and laboratory parameters in homozygous sickle cell disease [SCD]. Subjects and Methods: Steady-state clinical and laboratory data were obtained from the medical records of 126 male patients seen in the clinic over a 7-year period. Estimated prevalence rates, correlation coefficients and independent t tests were calculated to assess the relationship between priapism and several important clinical and laboratory indices. Patient data on age, haemoglobin concentrations, the frequency of crises per annum, leucocyte counts, platelet counts, serum bilirubin and aspartate transaminase were evaluated. Results: The prevalence of priapism was determined to be 21.4%, and 22.2% of those affected had erectile dysfunction. There was a significant positive correlation between priapism and older age [p = 0.049] and lower leucocyte counts [p = 0.008]. There was no significant relationship with other clinical or laboratory indices. Conclusion: About 1 in 4 of all homozygous older SCD patients had pria- pism, and an approximately similar ratio developed erectile dysfunction; they also had lower steady-state leucocyte counts. Other clinical and laboratory indicators of disease severity in SCD did not positively correlate with the occurrence of priapism, and this may imply an alternative pathogenetic mechanism

Ophthalmic manifestations of leukemia in a tertiary hospital population of adult Nigerian Africans

To determine the prevalence and pattern of leukemic ophthalmopathy among adults at the University of Nigeria Teaching Hospital [UNTH], Enugu, south-eastern, Nigeria. This prospective, observational case series surveyed adult leukemia patients presenting at UNTH's departments of Hematology/Immunology and Ophthalmology from July 2003 to August 2008. The demographic profile, clinical data from for each individual in the cohort were statistically collated and analyzed. A P <0.05 was considered as statistically significant. There were 72 participants [45 males and 27 females], aged 32.7 +/- 9.8 years [range, 18 years to 72 years]. Leukemic ophthalmopathy was present in 77.8% of subjects. The leading ophthalmic manifestations of leukemia were retinal vascular abnormalities in 50.0% of subjects, conjunctival pallor in 27.8% of subjects, sub-conjunctival hemorrhage in 19.4% of subjects, and retinal hemorrhage in 16.7% of subjects. Ocular co-morbidity was present in 47.2% of subjects. Vision loss occurred in 37.5% of subjects, of which 32.1% was leukemia related, and the remaining due to ocular co-morbidity. Leukemic ophthalmopathy was more prevalent in chronic leukemia [P <0.05], frequently affected the ocular posterior segment [P < 0.05], and often resulted from secondary hematologic complications [P <0.05]. There was no gender difference in the prevalence of leukemia [P = 0.0822] or leukemic ophthalmopathy [P = 0.6624]. The prevalence of leukemic ophthalmopathy in Enugu is high. It is often associated with significant ocular co-morbidity and vision loss. These have implications for clinicians involved in leukemia management. Early diagnosis and regular ophthalmic examinations are recommended to optimize treatment outcomes
