ABSTRACT

OBJECTIVE: The osteoporosis in thyroid disorder has the lowest report especially in sub-Saharan Africa. This study aims to determine the prevalence, predictive factors, and characteristics of osteoporosis in hyperthyroid patients. METHOD: Forty (40) hyperthyroid patients and healthy controls ages 21-50 years were recruited in this study. Questionnaires were administered to capture bio- and clinical data. Biochemical tests included blood, thyroid functions, intact parathyroid hormone, corrected calcium, and 25-hydroxyvitamin D tests. Bone mineral density (BMD) was also evaluated. Data were analyzed using the SPSS 21. A p value < 0.05 was regarded as significant. RESULTS: Osteoporosis was observed in 18 (45%) of study subjects, 13 (72.2%) females and 5 (27.8%) males, respectively. The BMD of the hyperthyroid patients had a negative correlation with free triiodothyronine, FT3 (r = -0.49, p = 0.005), FT4 (r = -0.33, p = 0.009), corrected calcium (r = -0.31, p = 0.039), alkaline phosphatase (r = -0.53, p < 0.001), and osteocalcin (r = -0.61, p < 0.001). Conversely, a positive association with thyroid-stimulating hormone (TSH) (r = 0.54, p < 0.001) was observed. Multiple regression showed osteocalcin (p < 0.001) and TSH (p = 0.015) as independent predictors of osteoporosis. CONCLUSION: Thyrotoxicosis is a risk factor for osteoporosis occurrence, and we recommend routine screening for this bone disease in persons over 20 years old with this disorder.

ABSTRACT

BACKGROUND: Identifying the risk factors for diabetes mellitus related foot ulceration would save more limbs from amputation. This report focuses on the determining the burden of peripheral arterial disease and neuropathy in persons with diabetes mellitus (DM). METHODS: This is a descriptive study carried out in the Diabetic Clinic of the Lagos State University Teaching Hospital in patients with DM who had no past/present history of foot ulceration. Biothesiometry was employed and ankle brachial pressure indices were measured to evaluate for neuropathy and peripheral arterial disease (PAD) respectively. RESULTS: A total of 225 persons living with DM who met inclusion criteria were recruited consecutively over a 3 months period. Age range was 28-87 years with the mean [61.4 (10.8)] and median (63) years respectively. Patients symptomatic for neuropathy and PAD were 37 and 40 % respectively of the study population. An older age of >60 years and poor glycaemic control were potential predictors of neuropathy. Neuropathy and PAD occurred commonly in the seventh decade of life. CONCLUSION: Given the fairly high proportions of neuropathy and PAD in our patients with DM, we recommend that they be routinely examined in persons with DM.

ABSTRACT

BACKGROUND: Stroke is a major health issue in Nigeria and it is also a common cause of emergency admissions. Stroke often results in increased morbidity, mortality and reduced quality of life in people thus affected. The risk factors for stroke include metabolic abnormalities such as dyslipidaemia and diabetes mellitus (DM). The stress of an acute stroke may present with hyperglycaemia and in persons without a prior history of DM, may be a pointer to stress hyperglycaemia or undiagnosed DM. METHODOLOGY: This was a cross sectional study carried out over a period of one year in a teaching hospital in Lagos, Nigeria. Patients with acute stroke admitted to the hospital within three days of the episode of stroke and who met other inclusion criteria for the Study were consecutively recruited. Clinically relevant data was documented and biochemical assessments were carried out within three days of hospitalization. Tests for lipid profile, glycosylated haemoglobin(HbA1c), and blood glucose at presentation were carried out. The presence of past history of DM, undiagnosed DM, stress hyperglycaemia and abnormal lipid profile were noted. Students t test and Chi square were the statistical tests employed. RESULTS: A total of 137 persons with stroke were recruited of which 107 (76%) met the defining criteria for ischaemic stroke. The mean age and age range of the Study subjects were 62.2 (11.7) and 26-89 years respectively. The Study subjects were classified according to their glycaemic status into the following categories viz; stress hyperglycaemia, euglycaemia, DM and previously undiagnosed DM. Stress hyperglycaemia occurred commonly in the fifth decade of life and its incidence was comparable between those with cerebral and haemorrhagic stroke. The commonly occurring lipid abnormalities were elevated LDL-C and low HDL. CONCLUSIONS: The detection of abnormal metabolic milieu is a window of opportunity for aggressive management in persons with stroke as this will improve outcome. Routine screening for hyperglycaemia in persons with stroke using glycosylated haemoglobin tests and blood glucose may uncover previously undiagnosed DM.

ABSTRACT

BACKGROUND: Achieving good glycemic control is of paramount importance in the reduction of diabetes mellitus (DM) associated morbidity and mortality. Insulin plays a key role in the management of DM but unfortunately whilst some healthcare providers present insulin as a treatment of last resort , patients on insulin often have insulin related issues such as needle phobias, fear of hypoglycaemia, weight gain and in developing countries, costs. This Report aims at assessing insulin prescription pattern, insulin costs and issues associated with adherence. METHODS: This was a Cross-sectional observation Study whereby 160 patients with DM who were on insulin solely or in combination with oral hypoglycaemic agents were recruited over a 6 month period. Information obtained from the Study subjects pertained to their histories of DM, types of insulin, insulin costs, adherence issues and insulin delivery devices. Long and short term glycaemic control were determined and evaluated for possible relation to insulin adherence. Test statistics used were chi square, t test and binary regression. RESULTS: Insulin adherence was noted in 123-77% of the Study subjects and this was comparable between persons with type 1 DM and those with type 2 DM. The mean glycosylated haemoglobin values were significantly higher in those who admitted to non insulin adherence compared to those who adhered to their insulin regimen (9.7% (2.3) Vs 8.6% (2.1), p = 0.01). Reasons proffered by Respondents for non insulin adherence included high costs-15(41%), inconvenience -15 (41%) and needle pain-79)18%. A greater proportion of persons who self injected insulin adhered to insulin prescriptions compared to those who did not self inject and thus had better glycaemic control. Shorter duration of DM and older age were found to be predictors of adherence to insulin prescription.The monthly mean costs of insulin for those who earned an income was 5212.8 Nigerian naira which is equivalent to 33.1 US dollars and we estimated that persons on a minimum wage would spend 29% of their monthly income on the procurement of insulin. CONCLUSIONS: Health related costs, age, duration of DM and insulin associated side effects are some of the factors implicated in adherence to insulin prescription.

ABSTRACT

Tetanus is a life threatening preventable infection with a high mortality. Our aim was to determine the current case fatality rate at our centre in a retrospective case review of patients aged > 10 years who had been hospitalized with tetanus between August 2006 and July 2011. We show the intrahospital case fatality rate. Data are based on 176 cases for which we had sufficient information. There was a preponderance of males (3.09:1); 167 (95%) had generalized tetanus and nine (5%) had localized tetanus. The overall case fatality rate was 56.2% and was higher in males (64.4%) than females (27.9%; P = 0.0001). In a multivariate analysis, older age (P = 0.000), male gender (P = 0.005) and a longer duration of admission (P = 0.004) were significant determinants of outcome. The case fatality rate of tetanus has declined at our centre from 70% between January 2004 and March 2006 to 56.2% currently. Improved facilities are required in order to significantly reduce adverse outcome from tetanus.

ABSTRACT

INTRODUCTION: Latent autoimmune diabetes in adults (LADA) is an entity characterized by the presence of GAD autoantibodies. LADA is largely understudied and underreported amongst Nigerians with Diabetes Mellitus (DM). We undertook to document the Prevalence, clinical and biochemical characteristics of LADA in a subset of Nigerians who hitherto had been treated for type 2 DM. METHODS: This is a cross-sectional study conducted on 235 patients being managed for type 2 DM. The diagnosis of LADA was made in the presence of Glutamic Acid Decarboxylase autoantibody (GADA) positivity in the study subjects. Thereafter persons with LADA were compared with those without LADA. Clinical parameters such as demographic data, history of diabetes mellitus (DM) and its complications were obtained, biochemical parameters including Fasting blood glucose (FBG), C-peptide, glycated haemoglobin (HbA1c) and lipid parameters were compared in both groups of Study subject. Test statistics used were Student t- test and χ 2. SPSS was used for data analysis. RESULTS: Thirty three out of 235 of the Study subjects were GADA positive, giving a prevalence of 14%. The mean age (SD) of the subjects with LADA is 53.24(7.22) with an age range of 30-63 years. Majority (48%) of LADA subjects were in the 50-59 age category. There was no significant difference in the proportion of males and females with LADA (p = 0.3). 37% of patients with LADA were on insulin for glycaemic control. Three (3) LADA subjects had history/clinical evidence of autoimmune thyroid disease. 66% of LADA were in the overweight/obese category. LADA subjects had significant poor long term glycaemic control compared with anti-GAD negative subjects (p = 0.026). About half of LADA subjects were insulinopaenic. LADA subjects had lower levels of total cholesterol than GADA-ve subjects (p = 0.03). A higher proportion of LADA had evidence of microvascular complications of DM compared with antiGAD negative individuals. CONCLUSION: The diagnosis of LADA should be entertained in overweight/obese persons from the fourth decade of life presenting with DM. Pharmacotherapy with insulin is a potential means of managing hyperglycaemia in this group of patients especially since a significant proportion are insulinopaenic. The Prevalence of LADA in our patients is comparable to what obtains in Ghanaian and Caucasian populations.

ABSTRACT

BACKGROUND: Diabetes Mellitus is the commonest endocrine-metabolic disorder in Nigeria similar to the experience in other parts of the world. The aim was to assess the clinical and laboratory profile, and evaluate the quality of care of Nigerian diabetics with a view to planning improved diabetes care. MATERIALS AND METHODS: In a multicenter study across seven tertiary health centers in Nigeria, the clinical and laboratory parameters of diabetic out-patients were evaluated. Clinical parameters studied include type of diabetes, anthropometry, and blood pressure (BP) status, chronic complications of diabetes, and treatment types. Laboratory data assessed included fasting plasma glucose (FPG), 2-h post-prandial (2-HrPP) glucose, glycated hemoglobin (HbA1c), urinalysis, serum lipids, electrolytes, urea, and creatinine. RESULTS: A total of 531 patients, 209 (39.4%) males and 322 (60.6%) females enrolled. The mean age of the patients was 57.1 ± 12.3 years with the mean duration of diabetes of 8.8 ± 6.6 years. Majority (95.4%) had type 2 diabetes mellitus (DM) compared to type 1 DM (4.6%), with P < 0.001. The mean FPG, 2-HrPP glucose, and HbA1c were 8.1 ± 3.9 mmol/L, 10.6 ± 4.6 mmol/L, and 8.3 ± 2.2%, respectively. Only 170 (32.4%) and 100 (20.4%) patients achieved the ADA and IDF glycemic targets, respectively. Most patients (72.8%) did not practice self-monitoring of blood glucose. Hypertension was found in 322 (60.9%), with mean systolic BP 142.0 ± 23.7 mmHg, and mean diastolic BP 80.7 ± 12.7 mmHg. Diabetic complications found were peripheral neuropathy (59.2%), retinopathy (35.5%), cataracts (25.2%), cerebrovascular disease (4.7%), diabetic foot ulcers (16.0%), and nephropathy (3.2%). CONCLUSION: Most Nigerian diabetics have suboptimal glycemic control, are hypertensives, and have chronic complications of DM. Improved quality of care and treatment to target is recommended to reduce diabetes-related morbidity and mortality.

ABSTRACT

INTRODUCTION: Nigeria is a developing country that is currently witnessing an upsurge in diabetes mellitus and obesity with its antecedent consequences. There is also a fairly high prevalence of asthma affecting an estimated 10.7% of the population. There is no data presently on the possible presence of metabolic syndrome in Nigerian living with asthma. The study was conceived to determine the prevalence of metabolic syndrome among a population of asthmatics seen in our practice. We also attempt to compare asthma severity, control and pulmonary function tests in asthmatics with metabolic syndrome and those without. METHODOLOGY: This cross-sectional study was carried out at the asthma clinic of a tertiary teaching hospital. Ethical clearance was obtained from the research and ethics committee of the hospital. Written consent was obtained from the participants. Interviewer based questionnaire was used to obtain required information, anthropometric indices were recorded and clinical examinations done. Pulmonary function tests were carried out using desktop Alpha Spirometer model 6000 made by Vitalograph UK (2007). Blood pressure was measured using sphygmomanometer in mmHg. Fasting venous blood was taken for blood sugar and lipid profile. Metabolic syndrome was defined by the international diabetes Federation (IDF) criteria. RESULT: One hundred and fifty eight (158) asthmatics participated in the study comprising of 63 (39.9%) males and 95(60.1%) females. The age range was 14-78 years with a mean of 46.48+/-17.00 years. The mean duration of asthma diagnosis was 13.95+/-12.14 years. The prevalence of hypertension was 29.1%. 17 (10.8%) had fasting blood sugar above 100 mg/dl. Abdominal obesity was present in 78 (49.5%). The mean total cholesterol was 192.63+/-40.7 mg/dl. HDL was low in 21(22%) of female and 3 (4.8%) male. The prevalence of metabolic syndrome was 17.7%, affecting 28 asthma patients. Asthma control was affected by the presence of metabolic syndrome. P < 0.05. The pulmonary function test was not significantly affected by presence of metabolic syndrome. CONCLUSION: Metabolic syndrome prevalence is high in the population of asthma patients studied. It is therefore important to screen patient with asthma for this condition and treat to improve outcome.

ABSTRACT

BACKGROUND: The objective of this study was to determine the prevalence of the metabolic syndrome and its components in people with thyroid disorders. MATERIALS AND METHODS: 112 subjects with a history of thyroid disorders were consecutively enrolled for the study. Clinical data were obtained by interviewing the patients and referring to their case folders and prescriptions. The subjects were categorized into three: thyrotoxic, those with hypothyroidism and those with nontoxic goiters, based on clinical parameters and or thyroid function tests. The study subjects were weighed and their anthropometric indices were documented. The laboratory parameters that were analyzed included total cholesterol, high-density and low-density cholesterol and triglyceride. Statistical analysis was performed using Student's t test, one-way analysis of variance (ANOVA) test and chi-square test. RESULTS: The study subjects were aged between 14 and 76 years, with a mean age of 44.5 years, and the female:male ratio was 97:15. The mean age and anthropometric indices were comparable in subjects with thyrotoxicosis, hypothyroidism and euthyroidism. The overall prevalence of the metabolic syndrome was 28% and the frequency of occurrence of the metabolic syndrome in subjects with thyrotoxicosis, hypothyroidism and nontoxic goiter was 24%, 40% and 42%, respectively. The commonest occurring metabolic syndrome defining criterion was dysglycemia, while hypertension and elevated triglyceride were the least documented of the criteria. CONCLUSION: Metabolic syndrome occurs in 1 in every 4 persons with thyroid disorders, and as such, routine screening for this cardiovascular risk factor may be of benefit in this group of people, especially in those with hypothyroidism.

ABSTRACT

OBJECTIVE: To determine the frequency of occurrence of hypoadrenalism in patients with human immunodeficiency virus (HIV) infection and document the clinical correlates of hypoadrenalism for this group of patients. SUBJECTS AND METHODS: A descriptive study was carried out on 66 hospitalized HIV patients in a semi-urban setting of South Africa. Hypoadrenalism was diagnosed based on a basal cortisol level of less than 400 nmol/l with or without overt signs and symptoms. Clinical and biochemical parameters of hypoadrenalism were compared between subjects with suboptimal and normal cortisol levels. Statistical analysis included Student's t test, χ(2) and Pearson's correlation coefficient tests. RESULTS: The prevalence of hypoadrenalism was 27% with a high occurrence of contributory factors (cytomegalovirus infection in 100% and tuberculosis in 68.2% of the study subjects). Typical features of hypoadrenalism included: hyponatremia, 19.6%; hyperkalemia, 6.1%; mucosal hyperpigmentation, 12%, and loss of axillary hair, 15%. Comparison of clinical and biochemical parameters of hypoadrenalism did not show a correlation between CD4 count and cortisol levels (r = 0.1 and p = 0.3). CONCLUSION: The prevalence of hypoadrenalism in our patients with HIV infection was high and the clinical features were comparable in subjects with normal and subnormal cortisol levels.

ABSTRACT

BACKGROUND: Liver disease continues to be a major cause of morbidity and mortality in sub-Saharan Africa, including Nigeria, due to the high endemicity of viral hepatitis B. However non-alcoholic fatty liver disease may be an important contributory factor. The impact of fatty liver disease in our region has not been evaluated. AIM: To determine the prevalence of non-alcoholic fatty liver disease (NAFLD) among a population of diabetic (DM) subjects attending the endocrine clinic of LASUTH compared with non-diabetic subjects; ascertain other contributing factors and compare the occurrence of the metabolic syndrome in subjects with and without NAFLD. METHODOLOGY: Consecutive patients who satisfy the study criteria were enrolled. An investigator- administered questionnaire was used to determine symptoms of liver disease, followed by physical examination to obtain anthropometric indices as well as signs of liver disease. Abdominal scan was performed to determine radiologic evidence of fatty liver and fasting blood samples were collected from for the measurement of fasting lipid profile, glucose, liver biochemistry and serology for hepatitis B and C markers. RESULTS: One hundred and fifty subjects, mean age 56 years (standard deviation = 9, range 20-80 yr) and gender ratio (F: M) of 83:67(55%:45%), were recruited. 106 were diabetics and 44 non-diabetics. The overall prevalence of NAFLD amongst all study subjects was 8.7%. The prevalence rate of NAFLD was higher in the DM cases than in the Control subjects but this difference was not statistically significant (9.5 vs. 4.5%, p = 0.2). Only one of the subjects with fatty liver disease had elevated transaminase levels (steatohepatitis) and also had type 2 DM. Central obesity as measured by waist circumference (WC) and SGPT levels were significantly higher in people with fatty liver. The mean body mass index (BMI) of diabetic and non-diabetic patients was similar (31 vs. 30 kg/m(2)). The prevalence of the metabolic syndrome was higher in the subjects with NAFLD than in those without fatty liver disease but this difference was not statistically significant (p = 0.8). CONCLUSION: Non-alcoholic fatty liver disease is present in Africa but is less than what one would expect based on American and European studies.

ABSTRACT

BACKGROUND: There is limited literature on hypernatreamia in the setting of hyperglycaemic crisis. This is despite the fact that the presence of hypernatreamia may impact on the classification of hyperglycaemic crisis and its management particularly with regards to the nature of fluid therapy. We determined the prevalence of hypernatreamia and its associated factors at presentation for hyperglycaemic crisis. METHODS: This was a retrospective review of data for hyperglycaemic crisis admissions in Nelson Mandela Academic Hospital, Mthatha, South Africa. The prevalence of hypernatreamia (uncorrected Serum Sodium at presentation >145 mmol/L) was determined. Hyperosmolality was defined by calculated effective osmolality >320 mosmols/Kg. Multivariate logistic regression was undertaken using variables that were statistically significant in univariate analysis to ascertain those that were independently associated (Odds Ratio (OR) with 95% Confidence Interval (CI)) with hypernatreamia. RESULTS: The prevalence of hypernatreamia in our admissions for hyperglycaemic crisis was 11.7% (n = 32/273 including 171 females and 102 males). All admissions with hypernatreamia met the criteria for hyperosmolality. Age ≥ 60 years (OR = 3.9 95% CI 1.3-12.3; P = 0.018), Altered level of consciousness (OR = 8.8 95% CI 2.3-32.8; P < 0.001) and a new diagnosis of diabetes (OR = 3.7 95%CI 1.2-11.5; P = 0.025) were independently associated with hypernatreamia. CONCLUSION: The prevalence rate of hypernatreamia in hyperglycaemic admissions was high with all hypernatreamic admissions meeting the criteria for hyperosmolality. Advanced age, altered conscious level and a new diagnosis of diabetes were independently associated with hypernatreamia.

ABSTRACT

BACKGROUND: Acute Phase Reactants (APRs) have a wide range of activities that contribute to host defense. The aim of this report was to evaluate the dynamics and magnitude of these proteins in various microvascular complications in diabetes mellitus (DM). We also sought to assess the predictive values of APRs and other clinical variables for microvascular complications in DM. METHODS: This was a case control study carried out in 200 Nigerian subjects with type 2 DM and 100 sex and age matched healthy controls. The studied APRs included C-reactive protein, beta 2 microglobulin, fibrinogen and lipoprotein (a). RESULTS: The mean values of the APRs were significantly higher in type 2 DM compared with the controls and were observed in higher concentrations in those with microvascular complications, except beta 2 microglobulin. Presence of microvascular complications was observed in those with dilated fundus examination (retinopathy), symptom score of 3.0 (neuropathy), urea and creatinine levels above 50mg% and 1.5mg%, respectively, with significant proteinuria (nephropathy). Significant increase in mean ± SEM values of lipoprotein (a) was observed in diabetic retinopathy in comparison with those without complications (25.76 ± 1.13 mg/dl vs. 22.37 ± 0.73 mg/dl, p = 0.005). Elevated C-reactive protein was observed in diabetic neuropathy in comparison with those without complications (11.43 ± 2.33 u/ml vs. 8.30 ± 1.15 u/ml, p = 0.048). Increased beta 2 microglobulin levels were observed in patients with diabetic foot ulcers in comparison with those without complications (3.04 ± 0.51 mg/dl vs. 2.54 ± 0.14 mg/dl, p = 0.049). Circulating levels of Lipoprotein (a) predicted retinopathy in DM with both good and poor long-term glycemic control while duration of DM predicted the occurrence of foot ulcers.. CONCLUSIONS: Increased level of APRs was associated with a number of microvascular complications and may play a role in the pathogenesis.

ABSTRACT

BACKGROUND: Lipoprotein (a) (LP (a) is an independent cardiovascular risk factor that is not widely studied in people of sub-Saharan African origin. The aim of this report is to determine the frequency of occurrence of elevated Lp (a) and possible relationship with total cholesterol (TCHOL), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG), C reactive protein (CRP) and serum uric acid (SUA). METHODS: This is a cross sectional study carried out in 200 Nigerian patients with type 2 DM and 100 sex and age matched healthy Controls aged between 32-86 years. We determined the frequency of occurrence of elevated Lp (a) levels in the study subjects and compared clinical and biochemical variables between type 2 diabetic patients and non-diabetic patients. Clinical and biochemical parameters were also compared between subjects with type 2 DM who had elevated LP (a) and normal LP (a) levels. Long term glycaemic control using glycosylated haemoglobin was determined and compared in the study subjects. Test statistics used include chi square, correlation coefficient analysis and Student's t test. RESULTS: The mean Lp(a) concentration differed significantly between type 2 diabetic patients and the Control subjects (18.7 (5.8) mg/dl vs 23 (6.8) mg/dl, 0.00001). Similarly, the prevalence of high LP (a) levels in type 2 DM patients was significantly higher than that of the Control subjects (12.5% vs 4%, p-0.019). The mean levels of the lipid profile parameters (TCHOL, LDL-C, TG, LDL/HDL) and CRP were significantly higher in DM patients than in the Control subjects. The mean LP (a) levels were comparable in both sexes and in DM subjects with and without hypertension. TG was the only parameter that differed significantly between subjects with elevated Lp (a) levels and those with normal Lp (a) levels. There was a significant positive correlation (r) between Lp(a) levels and TG, LDL-C. TCHOL, LDL/HDL and uric acid. No association was found between Lp(a) and clinical parameters such as age and anthropometric indices. CONCLUSION: We have showed that Lp (a), CRP and other CVS risk factors cluster more in patients with DM than non DM patients. Serum Lp (a) levels are not associated with anthropometric and glycaemic indices.

ABSTRACT

BACKGROUND: Elevated serum uric acid levels (SUA) have been associated with an increased risk of cardiovascular diseases and the metabolic syndrome (MetS) and are often reported to be higher in females than in males. The aim of this report is to determine the prevalence and clinical correlates of hyperuricaemia and also to evaluate associations with the MetS in people with type 2 diabetes mellitus (DM). METHODS: This was a cross-sectional study conducted in people with type 2 DM in Lagos, Nigeria. Hyperuricaemia was defined by cut-off values of > 7 mg/dl for men and > 6 mg/dl for women. The diagnosis of MetS was made using the new definition by the American Heart Association and other related bodies. Clinical and biochemical parameters were compared between subjects with hyperuricaemia and normouricaemia. Statistical analysis included usage of Student's t test, Pearson correlation coefficients, multivariate regression analysis and chi square. RESULTS: 601 patients with type 2 DM aged between 34-91 years were recruited for the study. The prevalence rates of hyperuricaemia and the MetS were 25% and 60% respectively. The frequency of occurrence of hyperuricaemia was comparable in both genders (59% vs 41%, p = 0.3). Although, the prevalence of the MetS in subjects with hyperuricaemia and normouricaemia was comparable (61 vs 56%, p = 0.1), a higher proportion of hyperuricaemic subjects had 3 or more components of the Mets compared with normouricaemic subjects. Possible predictors of hyperuricaemia include central obesity, smoking and elevated serum triglycerides (TG). SUA levels were found to be positively and significantly associated with serum TG (r = 0.2, p = 0.0001) and total cholesterol (r = 13, p = 0.001). CONCLUSION: The prevalence of hyperuricaemia in subjects with type 2 DM is comparable in both genders and possible predictors of hyperuricaemia are potentially modifiable. SUA is positively and significantly associated with serum TG and total cholesterol.

ABSTRACT

BACKGROUND: The Metabolic syndrome (MetS) is a cardiovascular risk factor of public health significance and of recent has become a topical issue. The prevalence of diabetes mellitus (DM) is on the increase and with this scenario, a possible increase in burden of DM which may be largely attributed to cardiovascular complications is expected. The objective of this report is to determine the prevalence of the MetS and compare gender characteristics in subjects with type 2 DM. METHODS: Subjects with type 2 DM were recruited from an urban hospital for the study. Clinical data was obtained by interviewing the patients and referring to their case folders. The anthropometric indices and blood pressure measurements were documented. Laboratory parameters analysed for included total cholesterol, high density and low density cholesterol, triglyceride and glycosylated haemoglobin. Statistical analysis included usage of Student's t test and chi square. RESULTS: 963 patients with type 2 DM aged between 35-85 years were recruited for the study. The main outcome measures included the prevalence of the metabolic syndrome and the gender differences of its components. The prevalence of the metabolic syndrome was 86%. The frequency of occurrence of the MetS was similar for men (83%) and women (86%) and increased with age in both sexes. The prevalence of MetS increased from 11% among participants aged 20 through 29 years to 89% in participants aged 70 through 79. In our patients with DM, the commonest occurring and least detected MetS defining parameters are central obesity and elevated triglyceride levels respectively. The components of the MetS that differed significantly in both sexes was HDL-C. The combination of the components of the MetS were comparable in both genders and 5.8% of the subjects with the MetS had all components of the MetS. CONCLUSION: The prevalence of the MetS in type 2DM is high in both genders and increases with age thus posing a potential high cardiovascular risk in this group of patients. The modifiable risk factors for the MetS should be a focus point in the management of subjects with type 2 DM.

ABSTRACT

BACKGROUND: Thyroid disorders are the second commonly encountered disorders in endocrine clinics and are significant causes of medical morbidity and mortality. It is pertinent to note that in the Nigerian setting, there are challenges of sub-optimal investigative and therapeutic facilities especially as concerning thyroid disorders hence there is underreporting of this important group of endocrine disorders from our part of the world. OBJECTIVE: The objective of this audit is to describe the pattern of presentation, investigation, management and outcome of thyroid disorders in patients attending the Lagos State University Teaching Hospital (LASUTH) Endocrine Center. SUBJECTS AND METHODS: This was a retrospective medical record review of patients with thyroid disorders who presented to the out patient department, the Medical and Emergency wards of LASUTH between June 2007-June 2009. The clinical, biochemical, serological and histological parameters were used to characterize the patients. Investigations done, treatment type, complications of thyroid disorders, hospitalization records and outcome of management were all documented. RESULTS: One hundred and seventy patients with thyroid disorders aged between 11 and 70 years were seen during the period under review. The male: female ratio was 1:7. Patients presenting with thyrotoxicosis were 128 in number thus giving an incidence rate per year of 64. Therapeutic options were essentially thionamides, betablockers, steroids, surgery, radioactive iodine (RAI) and thyroxine. The mean (SEM) duration of medication usage was 24.5 and the median medication duration was 24 months. RAI usage was low as its use was documented in 7% of the subjects with thyroid dysfunction. The rate of occurrence of variable glucose intolerance was 28% with frank diabetes mellitus diagnosed in 9% of the cases of hyperthyroidism. Thyroid storm, psychiatric manifestations, thyrocardiac disease and cerebrovascular diseases were indications for hospitalizations. Two deaths were documented and these were due to thyrocardiac disease and thyroid storm. CONCLUSION: RAI usage is underutilized and the thionamides are the main stay of treatment for people presenting with thyrotoxicosis. Given the peculiarities of presentation of thyroid disorders in our practice and the challenges of poor accessibility to diagnostic and therapeutic facilities, it is imperative that management guidelines that take into consideration our resource poor background be set up.

ABSTRACT

This prospective study assessed in-hospital mortality from diabetic foot ulcer in relation to the demographic, clinical and laboratory features at presentation. Forty-two patients admitted with diabetic foot ulcer were followed up from admission till discharge from hospital. Those who survived or died were compared for any differences in demographic, clinical and laboratory parameters at presentation. The mean age and duration of diabetes for the 42 patients were 56.1 +/- 1.9 years and 8.3 +/- 1.1 years, respectively. The in-hospital mortality rate amongst the 42 subjects was 40.5%. Ulcer grade > or =4, leucocytosis and anaemia were more prevalent in those who demised in comparison with survivors.

ABSTRACT

BACKGROUND: Diabetes mellitus (DM) is a disorder that is often associated with cardiovascular events and underlying lipid abnormalities. Cardiovascular complications are common causes of DM deaths in Nigeria yet dyslipidaemia is one aspect of DM that is underdiagnosed and undertreated in our patients. This report seeks to determine the prevalence and pattern of lipid abnormalities in Nigerians with types I and 2 DM. METHODS: A total of 600 patients with DM aged between 22 - 79 years were evaluated for lipid abnormalities. The anthropometric indices, glycosylated haemoglobin, pattern of DM treatment and co-morbidities were noted. Total cholesterol (TCHOL), triglyceride (TG), high density lipoproteins (HDL-C), low density lipoproteins cholesterol (LDL-C) levels and the atherogenic indices levels were documented. Test statistic used included student's t test and chi2. RESULTS: Well over half (89%) of the study subjects had lipid abnormalities and there was no statistically significant difference in the proportions of subjects with type 1 and 2 DM with lipid abnormalities. Elevated LDL-C, TCHOL, TG and reduced HDL-C were noted in 74%, 42%, 13%, and 53% respectively of the study subjects. The commonly noted combined lipid abnormalities were elevated TG and reduced HDL-C. Hypertension, significant histories of smoking and alcohol ingestion were found to be potential determinants of the occurrence of dyslipidaemia. Age, sex, type of DM and anthropometric indices were found to be determinants of the the pattern of dyslipidaemia. Only a small proportion - (8%)-of the subjects with dyslipidaemia were on treatment for it. CONCLUSION: Having defined the scope of dyslipidaemia in our patients and also highlighting its gross undertreatment, we hope that our data will help sensitize health care practitioners on screening for and treating dyslipidaemia. Elevated LDL-C and reduced HDL-C should be the primary targets of treatment in our patients with dyslipidaemia.

ABSTRACT

BACKGROUND: Hyperglycaemic emergencies are common acute complications of diabetes mellitus (DM) but unfortunately, there is a dearth of published data on this entity from Nigeria. This study attempts to describe the clinical and laboratory scenario associated with this complication of DM. METHODS: This study was carried out in DM patients who presented to an urban hospital in Nigeria with hyperglycaemic emergencies (HEs). The information extracted included biodata, laboratory data and hospitalization outcome. Outcome measures included mortality rates, case fatality rates and predictive factors for HEs mortality. Statistical tests used are chi2, Student's t test and logistic regression. RESULTS: A total of 111 subjects with HEs were recruited for the study. Diabetes ketoacidosis (DKA) and hyperosomolar hyperglycaemic state (HHS) accounted for 94 (85%) and 17 (15%) respectively of the HEs. The mean age (SD) of the subjects was 53.9 (14.4) years and their ages ranged from 22 to 86 years. DKA occurred in all subjects with type 1 DM and 73 (81%) of subjects with type 2 DM. The presence of HSS was noted in 17 (19%) of the subjects with type 2 DM.Hypokalaemia (HK) was documented in 41 (37%) of the study subjects. Elevated urea levels and hyponatraemia were noted more in subjects with DKA than in those subjects with HHS (57.5%,19% vs 53%,18%). The mortality rate for HEs in this report is 20% and the case fatality rates for DKA and HHS are 18% and 35% respectively.The predictive factors for HEs mortality include, sepsis, foot ulceration, previously undetected DM, hypokalaemia and being elderly. CONCLUSION: HHS carry a higher case fatality rate than DKA and the predictive factors for hyperglycaemic emergencies' mortality in the Nigerian with DM include foot ulcers, hypokalaemia and being elderly.
