The aim of this study was to evaluate the relationship between the RDW and fasting blood sugar/blood pressure, and compare the results from diabetics with nondiabetic controls. Methods: This was an unmatched case-control study involving 200 participants consisting of 100 diabetics and 100 nondiabetic controls. Blood (4.5 mL) was collected from all of the diabetics and nondiabetic controls, and placed into EDTA anticoagulant tubes. A full blood count was performed using the Sysmex KX-21N, a three-part auto analyzer able to run 19 parameters per sample, including RDW. Blood pressure was measured during sample collection and in a sitting position. Results: The mean fasting blood sugar level was 95.20±30.10 mg/dL in the controls, and 147.85±72.54 mg/dL in the diabetics. The mean blood pressures for diabetics was 138/90 mmHg and for non-diabetics 120/80 mmHg. The mean RDW-SD (RDW standard deviation) was 46.44±4.64 fl in the controls, and 46.84±3.18 in the diabetics. The mean RDW-CV (RDW coefficient of variation) was 14.74%±1.94% in controls, and 14.80±0.71 for diabetics. No statistically significant correlation was found between the RDW-SD and fasting blood sugar/blood pressure in the diabetics. A statistically significant positive correlation was found between the RDW-CV and blood pressure in the diabetics. Conclusion: A positive correlation between the RDW-CV and blood pressure was established in the diabetics in this study. Keywords: RDW, fasting blood sugar, type 2 DM

Background: Hyperthyroidism is a common endocrine disorder with multi-systemic effects, the least reported of which is bone loss and fractures. Objective: The aim was to evaluate the risk factors, pattern and frequency of bone fractures among Nigerians with hyperthyroidism. Methodology: An analytical study was undertaken of 40 patients with hyperthyroidism aged between 21 and 50 years. They were seen at the outpatient Endocrine, Diabetic and Metabolism (EDM) clinic of Lagos State University Teaching Hospital (LASUTH). Using an interviewer-administered questionnaire, information on sociodemographics, medical history, clinical and biochemical parameters and dual-energy X-ray absorptiometry (DXA) scan was obtained. Risk of fracture was assessed using WHO and ISCD risk calculators. During statistical analysis, quantitative and qualitative data were expressed as mean (SD) and percentages. Results: In all, 40 patients with hyperthyroidism were studied with a mean age of 36.16 (8.43) years. There were 32 females (80%, female:male ratio 4:1) and mean body mass index was 24.14 (4.3) kg/m. Hyperthyroidism was defined by Waynes' scoring index greater than 19 and confirmed by elevated thyroid hormones (FT4 39.44 (24.11) (pmol/l), FT3 12.13 (7.83) (pmol/l)) and suppressed TSH 0.26 (0.03) (u/U/ml). Increased bone turnover was documented by elevated bone formation markers (osteocalcin 45.7 (19.9) ng/ml and alkaline phosphatase 221.1 (143.46 IU/l)), bone resorption markers (24-hour calcium excretion 590.95 (506.1) mg/day). The mean BMD T- and Z-scores were reduced -2.0 (1.2). Bone loss was observed in 31 (72.5%) hyperthyroid subjects, but only three (7.5%) had fractures due to minor trauma. Conclusion: Bone fractures may not be uncommon in hyperthyroidism. Early screening for bone diseases should be encouraged to improve treatment outcome. [ABSTRACT FROM AUTHOR]

The major part of the burden of people with diabetes mellitus (DM) is their impaired quantity and quality of life. This is due to acute and chronic complications of which diabetic foot ulceration (DFU) takes the greatest toll. Most studies on the disease burden of DFU were carried out in developed countries, and to date, no indigenous study has addressed the burden of foot ulceration in Nigerians with DM. This study attempted to determine the disease burden of this important DM complication. The study was carried out at the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria. The working definition of disease burden encompassed prevalence, morbidity, mortality, and the direct economic costs of diabetes mellitus foot syndrome (DMFS). For determination of the estimates of prevalence, the 'capture-recapture' and intensive case-counting methods were used, mortality and morbidity were determined from records of admissions, and associated deaths over a 3-year period (1998-2000). The direct economic costs of foot ulceration were derived from the costs incurred from in-patient days, tests, drugs/medications, surgery, and other miscellaneous units of services. The total number of people with DM seen in LUTH from 1998 to 2000 was 1500, the hospital prevalence of DFU using the capture-recapture method being 9.5%. A total of 7253 medical admissions were made in this 3-year period, and of this number 827 (11.4%) were DM related. DFU-related admissions were 97 in number, and this made up 1.3% and 11.7% of the total medical and diabetes admissions, respectively. During this period, a total of 61 lower limb amputations were carried out and 26 (42.6%) of these were DM related. The proportion of medical deaths due to DMFS deaths was greater than the proportion of medical admissions due to DFU (P = .007). The case fatality of individuals with DFU was approximately 53%. A total number of 20 patients with DM foot ulcers were hospitalized during a 1-year period of the study (2003-2004). The majority had type 2 DM. A large majority (65%) of these patients had some form of surgery in addition to medical management of their condition. Mean costs for successfully treating a patient with DMFS was Nigerian Naira (NGN) 180,581.60. The total costs incurred ranged from NGN 20,400.00 to NGN 278,029.00. Drugs or medications accounted for the majority of the total costs incurred by the patients (46.9%). [ABSTRACT FROM AUTHOR]

Abstract: Diabetic foot ulcers (DFUs) remain important sequelae of diabetes (DM) which cause debilitating effects on the sufferer. The evolution of some aspects of epidemiology and the current clinical impact of DFUs was examined., Methods: A single-center prospective observational study. Study subjects were consecutively recruited., Results: Total medical admissions during the study period were 2288, 350 were DM related, out of these 112 were admitted for DFU. 32% of total DM admissions were for DFU. The mean age of the study subjects is 58 ± 11.0 range is from 35 years to 87 years. Males were slightly predominant (51.8%). Most of them were actively employed (92%), and the majority were in the 55 to 64 years age category. Most of them had not been diabetic for longer than 8 years (61%). The mean duration of DM is 8.32±7.27 years. The mean duration of ulcer at presentation was 72.0±138.13 days. The majority of the patients (80.3%) presented with severe (grades 3 to 5) ulcers, Wagner grade four was the most predominant. Regarding clinical outcome, 24 (24.7%) had an amputation, 3 of which were minor. The factor that was associated with amputation was concomitant heart failure - OR 6.00 CI 0.589-61.07, 0.498-4.856. Death occurred in 16 (18.4%). The factors associated with mortality were severe anemia OR 2.00 CI 0.65 - 6.113, severe renal impairment requiring dialysis OR 3.93 CI 0.232-66.5, concomitant stroke OR 8.42 CI 0.71-99.6, and peripheral arterial disease- OR 18.33 CI 2.27 -147 p-value- 0.006., Conclusion: The hallmark of DFU in this report is late presentation, it accounted for a significant proportion of the total medical admissions, although the case fatality of DFU reduced from previous reports from the center, mortality, and amputation rates are still unacceptably high. Concomittant heart failure was a factor of amputation. Mortality was associated with severe anemia, renal impairment and peripheral arterial disease., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Adeleye, Williams, Dada, Ugwu, Ogbera and Sodipo.)

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.

Introduction: Stroke is a major public health problem worldwide. Hypertension, diabetes mellitus, dyslipidaemia and smoking are some of the common modifiable risk factors in the occurrence of stroke. Therefore, this study was designed to assess the prevalence and patterns of dyslipidaemia among individuals with acute stroke., Methods: This is a retrospective descriptive cross-sectional study, carried out in the Departments of Medicine at the LAUTECH Teaching hospital, Ogbomoso and General Hospital, Orile-Agege, Lagos, South-West, Nigeria, over a 18-month period between September 2012 and February 2014. One hundred and six (106) patients with acute stroke confirmed with computed tomography (CT) brain scan were recruited. Clinical features, risk factors, lipid profiles and stroke patterns were identified., Results: Mean age was significantly higher in ischaemic stroke compared to haemorrhagic (64.08±10.87 Vs, 56.21±12.38years, p=0.001). There was slight male preponderance in both stroke types (1.3:1). Out of 106 patients, 65 (61.3%) had ischaemic stroke, 38 (35.8%) intracerebral haemorrhage and 3 (2.9%) with subarachnoid haemorrhage. Dyslipidaemia is the most frequent risk factor (85.9%), followed by hypertension (66.0%) and diabetes mellitus (15.1%). Dyslipidaemia was significantly higher in the ischaemic stroke compared to haemorrhagic. Reduced HDL-cholesterol is the most prevalent fraction of lipid abnormalities (74.5%)., Conclusion: Dyslipidaemia, particularly low HDL-C, was the most frequent risk factor in our patients with stroke. Hence, prevention of dyslipidaemia as well as other risk factors is key to reducing the burden of stroke in our country., Competing Interests: The authors decalre no competing interests.

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.

Objective: The objective is to document the clinical profile of diabetes mellitus (DM) in tuberculosis (TB)., Type of Study: This was a descriptive observational study., Methods: A total of 4000 persons aged above 12 years with a confirmed diagnosis of TB and on treatment were recruited. The study subjects were screened for DM and diagnoses were made on the basis of the WHO criteria. Clinical parameters were compared between persons with DM and those without DM., Results: Mean age was higher in patients with TB and DM than in persons without DM, and this difference was statistically significant (40.9 vs 39.6 years, p=0.0002). DM/TB comorbidity was noted in 480 persons and these made up 12.3% of the study population. Some clinical features of patients with TB who had DM included a positive family history of DM, a history of hypertension, and central obesity., Conclusions: Given the substantial burden of DM and TB comorbidity, we recommend that patients with TB be screened routinely for DM. However, further research is needed to clarify the risk factors for the occurrence of DM in TB.

Diabetes mellitus (DM) is a diverse group of metabolic disorders that is often associated with a high disease burden in developing countries such as Nigeria. In the early nineties, not much was known about DM in Nigeria and traditionally, people related DM to "curses" or "hexes" and diagnosis was made based on blood or urinary tests for glucose. Currently, oral hypoglycaemic agents but not insulin are readily accessible and acceptable to persons with DM. The cost of diabetes care is borne in most instances by individuals and often payment is "out of pocket"-this being a sequel of a poorly functional national health insurance scheme. An insulin requiring individual on a minimum wage would spend 29% of his monthly income on insulin. Complementary and alternative medicines are widely used by persons with DM and form an integral component of DM care. Towards reducing the burden of DM in Nigeria, we suggest that there be concerted efforts by healthcare professionals and stakeholders in the health industry to put in place preventative measures, a better functioning health insurance scheme and a structured DM program.

Introduction: HE are common acute complications of diabetes mellitus (DM) and include diabetic ketoacidosis (DKA), normo-osmolar hyperglycemic state (NHS) and hyperosmolar hyperglycemic state (HHS). They contribute a lot to the mortality and morbidity of DM. The clinical features include dehydration, hyperglycemia, altered mental status and ketosis. The basic mechanism of HE is a reduction in the net effective action of circulating insulin, resulting in hyperglycemia and ketonemia (in DKA) causing osmotic diuresis and electrolytes loss. Infection is a common precipitating factor. Measurement of serum C-peptide provides an accurate assessment of residual β-cell function and is a marker of insulin secretion in DM patients., Aim and Objectives: To assess the level of pancreatic beta cell function in HE patients, using the serum C-peptide., Methodology: The biodata and clinical characteristics of the 99 subjects were collated using a questionnaire. All subjects had their serum C-peptide, glucose, electrolytes, urea, creatinine levels, urine ketones determined at admission. Results of statistical analysis were expressed as mean ± standard deviation (SD). A p value <0.05 was regarded statistically significant. Correlation between levels of serum C-peptide and admission blood glucose levels and the duration of DM respectively was done., Results: The mean age of the subjects was 51 (SD ± 16) years and comparable in both sexes. Mean duration of DM was 6.3 (SD ± 7.1) years, with 35% newly diagnosed at admission. The types of HE in this study are: DKA (24.7%), NHS (36.1%), and HHS (39.2%). Mean blood glucose in this study was 685 mg/dL, significantly highest in HHS and lowest in NHS. Mean serum C-peptide level was 1.6 ng/dL. It was 0.9 ng/dL in subjects with DKA and NHS while 2.7 ng/dL in HHS (p>0.05). Main precipitating factors were poor drug compliance, new-onset of DM and infection., Conclusion: Most (70%) of subjects had poor pancreatic beta cell function, this may be a contributory factor to developing HE. Most subjects with high C-peptide levels had HHS.

Background: The aim of this report was to assess the efficacy and safety of a combination of vitamin E, an antioxidant, and Eve Primrose in the management of painful diabetes mellitus (DM) neuropathy., Materials and Methods: This was an interventional study that evaluated the efficacy and safety of a combination of vitamin E and Eve Primrose in the management of DM neuropathy. The study was conducted at the Diabetic Centre of the Lagos State University Teaching Hospital, Ikeja. Eighty individuals with type 2 DM who had painful neuropathy were recruited for this study, which took place for a duration of 1 year. The study subjects underwent clinical and biochemical assessment at baseline and were given vitamin E in a dose of 400 mg in combination with Eve Primrose in doses ranging 500-1000 mg/day. They were afterward assessed for relief of symptoms and possible untoward effects after 2 weeks and, thereafter, monthly for 3 months. The main outcome measure was amelioration of symptoms of neuropathy., Results: The mean age and age range of the study subjects were 58.2 years and 37-70 years, respectively. A total of 70 patients (88%) of the study population reported relief from neuropathic pains. Clinical parameters were comparable between the responders and non-responders. One characteristic feature of the non-responders was that they all had vibration perception threshold of ≥25 mV, which was indicative of severe neuropathy., Conclusion: The combination of vitamin E and Eve Primrose is beneficial in the management of mild to moderate diabetic neuropathy.

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.

Background: Tuberculosis (TB) and diabetes mellitus (DM) are two diseases that are individually relatively common and of immense public health significance globally. There is a growing awareness on a global scale on the possible relationship between TB and DM. Nigeria is a country with a high burden of TB and an increasing incidence of DM. We set out to determine the frequency of occurrence of undiagnosed DM in TB patients., Materials and Methods: This was an observational study that was carried out in TB patients recruited from 56 DOT centers in Lagos, Nigeria. The main objective of the study was to determine the disease burden of DM in patients with TB by comparing the frequency of occurrence of DM in TB to the occurrence of DM in people without TB. Screening was carried out by staff-nurses and community health workers-of these DOT facilities who all had capacity building on the detection of DM at the start of the project., Results: Of 4000 TB patients, a total of 480 (12.3%) had DM. Of the pool of DM patients, newly diagnosed cases of DM were 310 (8%) in number and previously known persons with DM were 170 (4.3%). The newly diagnosed cases of DM made up 64% of the cases of DM. In the study population without TB, a total of 112 (5.6%) had DM. The number of newly diagnosed cases of DM were 40 in number and these made up 2% of this study group. The number of persons who were already known to have DM was 72 and these made up 3.6% of the study population. New cases of DM made up 44% of the total number of cases of DM detected in persons without TB., Conclusion: The detection rates of DM in patients with TB are higher than in persons without TB. Given the fact that DM may negatively impact TB treatment, we suggest that routine screening be carried out for TB in persons with DM.

Introduction: Nigeria is a country saddled with a high tuberculosis (TB) and human immunodeficiency virus (HIV) burden but the possible combination of these communicable diseases with diabetes mellitus (DM) has been overlooked. We undertook to determine the burden of HIV and DM in persons with TB by documenting the prevalence rates of these disorders., Methods: This is a cross-sectional Study that was conducted within 54TB/DOT centers in Lagos State. A total of 3,376 persons with TB who were on antiTB drugs were screened for HIV and DM using standardized tests. Statistical analysis was performed using Students t test and chi square., Results: The frequency of occurrence of DM in TB and that of HIV in TB were comparable (4.8% Vs 3.5%). The Study subjects with DM were older, had higher waist circumference measurements and had higher proportions of hypertension compared to the subjects without DM. The combination of HIV and DM in TB was found in (0.3%). We also noted that DM in TB and HIV in TB occurred more frequently in the third and fourth decades of life., Conclusion: This study demonstrated the potential co existence of HIV, DM and Tuberculosis. It is therefore important that these two diseases are sought for in patients with TB considering the changing epidemiology of these diseases particularly in developing countries like Nigeria.

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.

Background: The prevalence of diabetes and prediabetes are increasingly high in developing countries, where detection rates remain very low. This manuscript discusses the rationale, challenges and opportunities for early detection of diabetes and prediabetes in developing countries., Methods: PubMed was searched up to March 2012 for studies addressing screening for hyperglycemia in developing countries. Relevant studies were summarized through key questions derived from the Wilson and Junger criteria., Results: In developing countries, diabetes predominantly affects working-age persons, has high rates of complications and devastating economic impacts. These countries are ill-equipped to handle advanced stages of the disease. There are acceptable and relatively simple tools that can aid screening in these countries. Interventions shown to be cost-effective in preventing diabetes and its complications in developed countries can be used in screen-detected people of developing countries. However, effective implementation of these interventions remains a challenge, and the costs and benefits of diabetes screening in these settings are less well-known. Implementing screening policies in developing countries will require health systems strengthening, through creative funding and staff training., Conclusions: For many compelling reasons, screening for hyperglycemia preferably targeted, should be a policy priority in developing countries. This will help reorient health systems toward cost-saving prevention., (Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.)

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.

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.

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.

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.

Objective: The clustering of cardiovascular risk factors and diseases has grievous implications on overall morbidity and mortality. There is however relative paucity of this information among the Nigerian population. This study was aimed at defining the prevalence of the clustering of hypertension (HT), diabetes mellitus (DM) and dyslipidemia (DYSL) in a Nigerian teaching hospital outpatient clinics population., Subjects and Methods: A cross sectional study of patients managed at the hypertension and diabetes clinics of the Lagos State University Teaching Hospital, Nigeria between January and December 2008. The baseline demographic characteristics, blood pressures, blood sugars and fasting lipid profiles were obtained retrospectively from hospital records. Using the standard criteria for the diagnosis of HT, DM and DYSL, the prevalence of these conditions and their respective clusters were determined., Results: A total of 506 patients were seen over this period, male; 234 (46.2%), female; 272(53.8%) with mean age of 57.35 (1.28) years. The prevalence of HT, DM and DYSL were 85%, 39.5% and 58.9% respectively. Concurrent HT and DYSL was the most prevalent cluster found in 146 patients (28.9%), followed by the clustering of the three co-morbidities of HT, DM and DYSL in 124 patients (24.5%).Other clusters were DM+HT; 49 (9.7%), DM+DYSL;13 (2.6%). 41.2% of the population had the clustering of at least two co-morbidities and about a quarter had the three conditions coexisting., Conclusion: There is a significant burden of the cardiovascular risk factors occurring in clusters in the Nigerian population studied. This calls for purposeful measures to control these risk factors.

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.

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.

Background: Thyroid disorders are common endocrine disorders encountered in the African continent. Environmental and nutritional factors are often implicated in the occurrence of some thyroid disorders that occur in this part of the world. This is a narrative review that seeks to document the pattern, prevalence, and management of thyroid disorders in the continent., Materials and Methods: The search engine used for this review were PubMed and Google scholar. All available articles on thyroid disorders from the sub-African continent, published until May 2011, were included., Results: Iodine deficiency disorders (IDD) which top the list of thyroid disorders and remain the commonest cause of thyroid disorders in the continent is often affected not only by the iodine status in the region but sometimes also by selenium deficiency and thiocyanate toxicity. The reported prevalence rates of endemic goiter range from 1% to 90% depending on the area of study with myxedematous cretinism still a prominent feature of IDD in only a few regions of the continent. The extent of autoimmune thyroid disorders remains unknown because of underdiagnosis and underreporting but the few available studies note a prevalence rate of 1.2% to 9.9% of which Graves diseases is the commonest of these groups of disorders. Rarer causes of thyroid dysfunction such as thyroid tuberculosis and amiodarone related causes are also documented in this review. The onset of new thyroid diseases following amiodarone usage was documented in 27.6% of persons treated for arrhythmia. Reports on thyroid malignancies (CA) in Africa abound and differentiated thyroid malignancies are noted to occur more commonly than the other forms of thyroid CA. The documented prevalence rates of thyroid CA in the African continent are as follows (papillary: 6.7-72.1%, follicular: 4.9-68%, anaplastic: 5-21.4%, and medullary: 2.6%-13.8%). For the differentiated thyroid CA, there is a changing trend toward the more frequent occurrence of papillary CA compared to follicular CA and this may be attributable to widespread iodization programs. Our review shows that diagnosis and evaluation of thyroid disorders are reliant in most regions of the continent on clinical acumen and suboptimal diagnostic facilities and expertise are what obtain in many practices. The frequently employed management options of thyroid disorders in the continent are pharmacological and surgical treatment modalities., Conclusion: Diagnosis and management of thyroid disorders in the African continent remain suboptimal. Thyroid registries may be helpful to determine the scope of the burden of thyroid disorders since this knowledge may help change policies on the approach to the management of these disorders.

Background: There are increasing reports on the association between the testosterone deficiency syndrome (TDS) and increased risk of development of the metabolic syndrome - a well recognized cardiovascular risk factor in men with diabetes mellitus., Objective: To determine the relationship between serum testosterone levels and components of the metabolic syndrome in Type 2 diabetes mellitus in Nigerian men., Methods: A total of 203 men with type 2 DM aged 30-86 years were evaluated for the testosterone deficiency syndrome (TDS). The diagnosis of the TDS or hypogonadism was made using a combination of clinical features of hypogonadism and subnormal levels of total testosterone. The presence of the metabolic syndrome was sought for in those with and without the TDS. The metabolic syndrome was diagnosed using the new criteria by the International Diabetes Federation and related bodies., Results: The overall prevalence rates of the TDS and the metabolic syndrome in the study subjects were 36% and 44% respectively. The proportion of the subjects with the Metabolic Syndrome (METS) was comparable in subjects with and without the TDS. (47% vs 43%, p = 0.6). Using the Mann Whitney U test, the mean rank of the testosterone level in the subjects with the METS was lower than that of those without the METS but this difference was not statistically significant (67.2 vs 66, p =0.9)., Conclusion: The frequency of occurrence of the metabolic syndrome in men with type 2DM is comparable in those with hypogonadism and those without hypogonadism. There is no correlation between serum testosterone levels and the metabolic syndrome defining parameters.

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.

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.

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., (Copyright © 2011 S.

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.

Background: Complementary and alternative medicine (CAM), an emerging aspect of the management of chronic diseases worldwide is not widely studied in Nigerian patients with diabetes mellitus (DM)., Objective: To assess the frequency and pattern of CAM utilization in people with DM ., Methods: This was a cross-sectional question-naire survey involving 263 patients with DM. Biodata, duration of DM, type and pattern of CAM utilization and adherence to prescribed medications were documented. The prevalence and possible determinants of CAM utilization were evaluated by determining the odds ratio for independent variables., Results: There were 263 respondents with a mean age of 60 (10.7) years and with ages ranging from 28-80 years. The prevalence of CAM usage was 46% and the female: male ratio was 2:1. Generally, CAM users were older than non-CAM users, (p= 0.006). The main forms of CAM used were biological based therapies and these included bitter leaf (Vernonia amygdalina), aloe vera, garlic, ginger, anlocal herbs. Adherence to prescribed medications was observed by 94% of respondents., Conclusion: We found that CAM usage is an important facet of management of DM among our patients with biological based therapies being the prevalent forms of CAM utilized. Despite CAM usage, adherence to prescribed medications was high. Further evaluation of the impact of CAM on glycaemia is needed.

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.

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.

Introduction: Sexual dysfunction (SD) in women with diabetes mellitus (DM) is an important but understudied aspect of DM complications in women with DM., Aim: This report is an attempt to document the prevalence, clinical correlates, and determinants of SD in a cross sectional study of women with diabetes mellitus (DM)., Main Outcome Measures: The main outcome measures were demographic, clinical parameters, psychological morbidity, and frequency of SD., Methods: A total of 58 married women with type 2 DM and 30 age-matched women who did not have DM had their sexual function and psychological status assessed using the Female Sexual Function Index (FSFI) and General Health questionnaires (GHQ 12) respectively. Glycemic control was assessed using glycosylated hemoglobin., Results: The prevalence of SD in women with DM and in the control population was 88% and 80%, respectively. The mean (standard deviation) FSFI score in the women with DM was significantly lower than that of the control group (16.2 [9.5] vs. 21 [8.5], P = 0.02). Women with DM attempted sex less frequently than those in the control group. Poor mental health status which was found to be associated with SD was noted more in women with DM than those in the control group., Conclusions: SD is high in women with and without DM. A possible determinant of SD in women with DM is psychological morbidity.

Acanthosis nigricans (AN) is a dermatological condition that is often associated with obesity and may be a physical marker of insulin resistance. Studies have documented a high prevalence rate of AN in people with diabetes mellitus (DM). However, there have been no Nigerian reports on AN and DM. This report bridges the information gap and documents the prevalence of AN in Nigerians with type 2 DM as well as its clinical correlates. Three hundred and forty consecutive subjects with type 2 DM were examined for the presence of AN and its associated clinical features. The prevalence of AN in type 2 DM in this report is 17%. Factors associated with AN include obesity, a family history of DM, female gender, the presence of hypertension and poor glycaemic control.

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.

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.
