ABSTRACT
Background. Although the association between lipoatrophy and highly active antiretroviral therapy (HAART) is well known, other nondrug factors may be associated with lipoatrophy in people living with HIV/AIDS (PLWHA). There are no reports of lipoatrophy from Nigeria, a country with the second largest number of PLWHA. We aimed to determine the prevalence, characteristics, and factors associated with lipoatrophy in a cohort of patients attending the HIV clinic in Lagos University Teaching Hospital, Nigeria. Methods. Two hundred and eighty-eight patients with HIV infection were recruited for the study. The study protocol involved administration of a questionnaire, targeted physical examination (including anthropometric indices and skin fold thickness), and bioelectrical impedance analysis measurements. Lipoatrophy was defined clinically. Results. Lipoatrophy was present in 75 (26.0%) persons. It was associated with lower body circumferences, skin fold thicknesses, and lower % body fat with preservation of skeletal muscle mass (all P < 0.05). Male gender and HAART use were the factors associated with lipoatrophy on multivariate analysis (P < 0.05). Conclusion. Lipoatrophy is frequently encountered in patients with HIV infection in Nigeria, with HAART use conferring an added factor in its development. There is need for more physician and patient awareness of this condition.
ABSTRACT
BACKGROUND: Infertility is a major problem in sickle cell disease patients, especially in males. In addition to low serum testosterone, other abnormalities involving the accessory sex organs, such as the seminal vesicles and the prostate gland, as well as marked decrease in ejaculate volume may be observed in male HbSS patients. Hence, the need to study the role of sex hormones as a cause of infertility in male HbSS patients. METHODS: An unmatched case-control study was performed using seventy-five consenting subjects from Lagos University Teaching Hospital. These included 47 patients with haemoglobin phenotype SS from the Sickle cell clinic and 28 volunteered medical students and members of staff with haemoglobin phenotype AA. Demographic data were obtained using a self-administered questionnaire. A total of 5 mls of blood was collected from each subject between 9.00 am & 11.am, and assayed for serum testosterone concentration. RESULTS: The concentrations of serum testosterone in HbSS patients ranged from 0.2 to 4.3 ng/ml with a mean of 1.28 ± 0.72 ng/ml whilst the values in HbAA controls ranged from 1.2 to 6.9 ng/ml with a mean of 2.63 ± 1.04 ng/ml. Seven (25.0%) of the 28 controls had serum testosterone concentration lower than the quoted reference (normal) range whereas 44 (93.6%) of the 47 HbSS subjects had serum testosterone concentration lower than the reference range. CONCLUSION: Overall, subjects with HbSS have significantly lower mean serum testosterone than HbAA controls.
ABSTRACT
Two-hundred Nigerians (65 years and above) were studied and compared with control (18-50 years). Haematocrit, haemoglobin, mean corpuscular haemoglobin concentration, mean corpuscular haemoglobin, mean corpuscular volume, platelets and ferritin were analyzed. Mean ferritin levels were 105 ± 30 µg/L and 72 ± 10 µg/L (males and females respectively). Mean MCV, MCH and MCHC were 94.6 ± 9.0 fl, 93.6 ± 9.0 fl, 31.5 ± 3.0 pg, 31.4 ± 4.4 pg, 348 ± 30 g/L, and 347 ± 42 g/L. Mean haematocrits were 37 ± 4%, 36 ± 4%, while mean haemoglobins levels were 132 ± 24 g/L and 129 ± 1 g/L. RBC counts were 4.1 ± 0.8 x 1012/L, and 4.0 ± 0.5 x 1012/L. Mean total WBC counts were 6.4 ± 1.5 x 109/L and 6.3 ± 0.7 x 109/L; mean platelets were 170 ± 60 x 109/L, 184 ± 5 x 109/L. All haematological parameters were similar in both aged males and females, except ferritin, haematocrit, RBC and haemoglobin, which were significantly higher in males (p< 0.05). Significant sex differences exist in all the parameters, of control except MCV and total WBC count. There were significant differences in all the haematological parameters between the controls and the aged (p< 0.05), and between the aged (65-84 years) and the very aged (85-105 years) (p< 0.05). Reference haematological range needs to be established for the elderly Nigerians.
