Alterations in haematological and clotting profile of post-menopausal women in Benin City, Nigeria

Background: The cessation of ovarian functions at menopause and the accompanying decline in the production of ovarian steroid hormones creates a unique set of health concerns for women. Reductions in sex steroid levels, particularly oestrogen, have been associated with various diseases and conditions, including bleeding disorders, coronary heart disease (CHD), osteoporosis, cognitive dysfunction, urinary incontinence, hot flushes, and mood changes, among others. Objective: To determine changes in haemorheological and clotting profile in post-menopausal women. Methods: Two hundred participants comprising one hundred and fifty post-menopausal women and fifty healthy pre-menopausal control subjects were studied. The investigations carried out include whole blood viscosity, plasma viscosity, fibrinogen concentration, Prothrombin time (PT), Activated partial thromboplastin time with kaolin (APTTK) levels and complete blood count using standard methods. Results: The mean age (p=0.01), platelet count (p= 0.013), neutrophil (p= 0.03), neutrophil to lymphocyte ratio (p= 0.045) and platelet to lymphocyte ratio (p=0.044) in postmenopausal women were significantly higher while lymphocyte count (p= 0.004) was significantly lower in postmenopausal compared to premenopausal women. Similarly, plasma oestradiol (p= 0.001), plasma viscosity (p= 0.03), relative blood viscosity (p= 0.03), whole blood viscosity (p= 0.03) and PTTK(p= 0.04) were significantly lower among postmenopausal women compared to premenopausal control subjects. Conclusion: Relative plasma viscosity correlated positively with age. There were significantly lower levels of haemorheological and clotting profile in post-menopausal women. These changes may be due to age or a decline in circulating oestrogen levels.

Lipid Profile in Sickle Cell Disease Patients with Chronic Kidney Disease

Background: Dyslipidaemia is reported to occur in patients with sickle cell disease as well as patients with chronic kidney disease irrespective of the haemoglobin genotype. This study aimed at evaluating lipid profile in subjects with sickle cell anaemia (HbSS); sickle cell trait (HbAS) and normal haemoglobin genotype (HbAA); and comparing the lipid parameters between sickle cell disease patients with and those without chronic kidney disease. Methods: A total of 66 patients with chronic kidney disease: 26 HbAA; 24 HbAS and 16 HbSS and 60 apparently healthy controls were recruited for the study. Lipoproteins; urea; creatinine; estimated glomerular filtration rate and electrolytes were determined using standard procedures in both patients and controls. Results: The mean total cholesterol; low density lipoproten cholesterol and high density lipoproten cholesterol in stable HbSS subjects were significantly lower (p

Hormonal abnormalities in azoospermic men in Kano, Northern Nigeria.

BACKGROUND & OBJECTIVES: We undertook this study to observe the pattern of hormonal abnormalities and testicular pathology in azoospermic male Africans in Kano, Northern Nigeria. METHODS: Eighty consecutive azoospermic infertile males attending fertility clinic in Aminu Kano Teaching Hospital, Kano, were selected for the study. Their semen were analyzed three times at eight weeks interval, after which serum follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and prolactin were assayed in serum samples, and histological examination of testicular biopsies done. RESULTS: Of the 80 subjects studied, 32 (40%) had abnormal hormonal levels, 48 (60%) had normal hormonal values and 36 (45%) had testicular pathology. INTERPRETATION & CONCLUSION: Endocrinopathies are common in azoospermia. Their contribution to male factor infertility cannot be overemphasized. The main reason for the endocrinopathies is not known but environmental factors, endocrine disruptors and genetic polymorphism have been suggested to be contributory.
