Insulin Injection Practices In People with Diabetes Mellitus

Background: The significance of achieving good glycaemic control cannot be over-emphasized as this goes a long way in the reduction of disease burden arising from diabetes mellitus. In Nigeria, insulin injections are still widely unacceptable thus posing a problem towards achieving optimal glycaemic control in insulin requiring diabetes patients. Aim: This study aimed to provide information on insulin usage in Nigeria. Patients and Methods: The study was carried out in the Lagos State University Teaching Hospital (LASUTH) and the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria. Participants were recruited from patients receiving care at the Diabetes Clinic of the above mentioned hospitals. It is a descriptive study in which 100 insulin-requiring diabetes patients were studied via the use of intervieweradministered questionnaire. Results: Essentially, insulin techniques, glycaemic control and complications of insulin usage were documented. Conclusions: The main form of insulin used is the human insulin. High cost of insulin is one of the major factors responsible for poor glycaemic control. For proper delivery of diabetes care, insulin, insulin pens and syringes must be available, accessible and at affordable cost. Keywords: Diabetes mellitus, Insulin injections, Glycaemic contro

Characterization of lipid parameters in diabetes mellitus – a Nigerian report

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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 χ².</p> <p>Results</p> <p>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.</p> <p>Conclusion</p> <p>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.</p

Mammograms and breast arterial calcifications: looking beyond breast cancer: a preliminary report

<p>Abstract</p> <p>Background</p> <p>To find out the prevalence, clinical and biochemical correlates of Breast Artery Calcification (BAC) in the Nigerian women.</p> <p>Findings</p> <p>This is a cross sectional study involving 54 consecutive adult female subjects sent to the Radiology Department of the Lagos State University Teaching Hospital (LASUTH), Ikeja-Lagos, Nigeria for screening and diagnostic mammography. The study was carried out for a period of five months.</p> <p>The prevalence of BAC was 20%. Ageing was found to be related to BAC. Cardiovascular risk factors including diabetes mellitus (DM), hypertension, obesity, alcohol ingestion, use of oral contraceptives and hormone replacement therapy, were not significantly related to the presence of BAC in this study.</p> <p>Conclusion</p> <p>This study showed that though the presence of BAC in a mammogram is related to age, it may not predict or serve as a significant marker for cardiovascular diseases (CVD) in women in our environment.</p

Lipoprotein (a), C-reactive protein and some metabolic cardiovascular risk factors in type 2 DM

<p>Abstract</p> <p>Background</p> <p>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).</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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.</p> <p>Conclusion</p> <p>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.</p

Breastfeeding policy and practices at the general paediatric outpatient clinic of a teaching hospital in Lagos, Nigeria

BACKGROUND: Hospitals have a role to play in supporting, protecting and promoting breastfeeding. The aim of this study was to describe hospital breastfeeding policy and practices and breastfeeding rates among mothers attending General Paediatric Outpatient Clinic at a tertiary hospital in Lagos, Nigeria. METHODS: This was a cross-sectional study involving paediatric nurses and doctors, as well as the mothers who brought their child to the General Paediatric Outpatient Clinic. Two sets of questionnaires, different in content, were administered to doctors and nurses, and to mothers of children aged 6-24 months, to assess hospital policy and breastfeeding rates, respectively. Stepwise multiple logistic regression analysis was used to examine factors associated with duration of breastfeeding. RESULTS: Although the hospital had a written breastfeeding policy copies of the policy were not clearly displayed in any of the units in the Paediatric department. Almost half the staff (48%; 60/125) were not aware of the policy. The hospital had no breastfeeding support group. Nearly three quarters (92/125) of the staff had received lactation management training. 36% (112/311) of mothers exclusively breastfed for six months, 42% (129/311) had stopped breastfeeding at the time of the survey. 67% (207/311) of babies were given infant formula, 85% (175/207) before 6 months. Women who had antenatal care in private hospitals and were Christian were more likely to breastfeed exclusively for 6 months. Low maternal education was the only factor associated with breastfeeding longer than 12 months. CONCLUSION: Breastfeeding practices and policy implementation at this outpatient clinic were suboptimal. We have identified a need for interventions to increase knowledge of the benefits of breastfeeding and to provide support for its longer term duration. We suggest that BFHI be considered across all facilities concerned with infant and early child health to disseminate appropriate information and promote an increase in exclusive breastfeeding for six months as well as the duration of breastfeeding

Clinical features, predictive factors and outcome of hyperglycaemic emergencies in a developing country

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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 <it>χ</it>², Student's t test and logistic regression.</p> <p>Results</p> <p>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.</p> <p>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.</p> <p>The predictive factors for HEs mortality include, sepsis, foot ulceration, previously undetected DM, hypokalaemia and being elderly.</p> <p>Conclusion</p> <p>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.</p

Screening for diabetes mellitus and humanimmunodefiency virus infection in personswith tuberculosis

Introduction. Nigeria is a country saddled with a high tubercu- losis (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 docu- menting 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 measure- ments 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 develop- ing countries like Nigeria

Surgical management of Diabetic foot ulcers: A Tanzanian university teaching hospital experience

\ud \ud Diabetic foot ulcers (DFUs) pose a therapeutic challenge to surgeons, especially in developing countries where health care resources are limited and the vast majority of patients present to health facilities late with advanced foot ulcers. A prospective descriptive study was done at Bugando Medical Centre from February 2008 to January 2010 to describe our experience in the surgical management of DFUs in our local environment and compare with what is known in the literature. Of the total 4238 diabetic patients seen at BMC during the period under study, 136 (3.2%) patients had DFUs. Males outnumbered females by the ratio of 1.2:1. Their mean age was 54.32 years (ranged 21-72years). Thirty-eight (27.9%) patients were newly diagnosed diabetic patients. The majority of patients (95.5%) had type 2 diabetes mellitus. The mean duration of diabetes was 8.2 years while the duration of DFUs was 18.34 weeks. Fourteen (10.3%) patients had previous history of foot ulcers and six (4.4%) patients had previous amputations. The forefoot was commonly affected in 60.3% of cases. Neuropathic ulcers were the most common type of DFUs in 57.4% of cases. Wagner's stage 4 and 5 ulcers were the most prevalent at 29.4% and 23.5% respectively. The majority of patients (72.1%) were treated surgically. Lower limb amputation was the most common surgical procedure performed in 56.7% of cases. The complication rate was (33.5%) and surgical site infection was the most common complication (18.8%). Bacterial profile revealed polymicrobial pattern and Staphylococcus aureus was the most frequent microorganism isolated. All the microorganisms isolated showed high resistance to commonly used antibiotics except for Meropenem and imipenem, which were 100% sensitive each respectively. The mean hospital stay was 36.24 ± 12.62 days (ranged 18-128 days). Mortality rate was 13.2%. Diabetic foot ulceration constitutes a major source of morbidity and mortality among patients with diabetes mellitus at Bugando Medical Centre and is the leading cause of non-traumatic lower limb amputation. A multidisciplinary team approach targeting at good glycaemic control, education on foot care and appropriate footware, control of infection and early surgical intervention is required in order to reduce the morbidity and mortality associated with DFUs. Due to polymicrobial infection and antibiotic resistance, surgical intervention must be concerned

Hyperuricaemia and the metabolic syndrome in type 2 DM

<p>Abstract</p> <p>Background</p> <p>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).</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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).</p> <p>Conclusion</p> <p>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.</p
