Plasma lipid levels in relation to disease severity in sickle cell anaemia in Abakaliki, Southeast Nigeria

Dyslipidaemia has been implicated in the pathophysiology of sickle cell disease (SCD) complications; hence its role requires further elucidation. Objectives: To investigate the relationship between disease severity and plasma lipid levels of patients with sickle cell anaemia. Methods: A cross-sectional study design was used for the survey. A total of 50 patients with sickle cell anaemia and 50 controls without SCD were recruited for the study. The clinical data and plasma lipid levels of lipids and haemoglobin parameters were analysed. Results: The majority of the participants were aged 18-25 years. Total plasma cholesterol and HDL-C were significantly lower in individuals with SCA compared with the controls (3.3±1.2 vs 4.2±1.2; p<0.001) and (1.3±0.5 vs 1.5±0.4; p = 0.038) respectively. Most patients with SCA had moderate disease severity (24; 48%). There was no statistically significant difference in the plasma levels of total cholesterol and HDL-C across the disease severity groups of SCA (p = 0.694 and 0.262). There was also no significant correlation between total cholesterol, HDL-C, and markers ofhaemolysis, haemoglobin F, and haemoglobin S levels. Conclusion: SCA is characterised by lower mean plasma TC and HDL than controls. However, no relationship was found between TC, HDL levels and SCD disease severity, markers of haemolysis, HbF and HbS levels. Further studies are required to ascertain the implications of plasma lipid levels in SCD

Cholesterolemia and triglyceridemia changes in adult with malaria in a hypo-endemic malaria region, Butembo-DR Congo

changes occur commonly among patients affected with malaria. This study aimed to assess lipid changes in blood among patients with malaria in Butembo, a hypoendemic region. Methods: This cross-sectional study, conducted in the Departments of Internal and Parasitology of Matanda Hospital, located in Butembo, from July 1st, 2020, to November 2, 2020; involved 100 patients diagnosed with malaria. Biochemical analyses carried out by three lab technicians were performed among patients who had positive malaria using positive thick film. Plasmodial species, the parasite density, the triglycerides, the total cholesterol, the HDL-cholesterol, the LDL-cholesterol were assessed. Results: Cholesteroleamia and HDLemia demonstrated a low level in 93% and in 61% of participants respectively; whereas 73% of cases showed an increased level of triglycerides in the blood. Lipidemia profile was independently associated with parasite density among patients with malaria. Conclusion: Although the lipid changes in the blood are not specific in the diagnosis of malaria, this study highlighted their status among patients with malaria. Further researches should be conducted to determine their impact on malaria outcomes. Therefore, dyslipidemia could be used in malaria screening.

Is vitamin D status associated with non-communicable disease risk in children? A cohort study

Background: Studies in children and adults have reported variations in 25-hydroxyvitamin D (25(OH)D), body mass index (BMI) and blood pressure (BP) over time. Furthermore, there has been a reported association of 25(OH)D with BMI, BP and lipid levels in some cross-sectional and longitudinal studies. Methods: This is a longitudinal study of a group of adolescents with measurements of 25(OH)D, BP, anthropometry and lipids at the ages of 11, 12 13, 15 and 18­20 years. For age-related changes, year 12 participants (n = 261) were matched with year 18­20 participants (n = 368), resulting in 200 paired participants. Longitudinal analyses using the Generalized Estimating Equations (GEE) comprised the following groups of participants, Year 11 (n = 288), Year 12 (n = 253), Year 13 (n = 292), Year 15 (n =238) and Year 18­20 (n = 368). The relationship of 25(OH)D with BMI, BP and lipid levels over a period of 10 years was assessed. Results: There were significant increases in mean BMI and BP, and decreases in 25(OH)D levels with age (all p-values < 0.0001).In females, systolic BP was significantly higher in older participants (18­20) years than younger participants (12 years), but 25(OH)D was significantly higher in younger than older participants. In males, there was significant increase in BP in participants between age 12 years and 18­20 years. 25(OH)D, total cholesterol (TC) and low-density lipoprotein (LDL-C) were significantly lower in 18­20-year-old participants compared with 12-year-old participants. Longitudinally, 25(OH)D was inversely associated with LDL-C. Conclusion: There is evidence of changes in 25(OH)D, BMI and BP in adolescents over a period of 10 years. After adjusting for covariates, BMI and LDL-C were significantly negatively associated with 25(OH)D, which suggests that vitamin D status might be associated positively with favourable lipid profiles in children and adolescents.

Lipid - Lowering Effect of a Mixture of Allium cepa bulb and Camellia sinensis Leaf Extracts in Rats fed on High fat Diet

The burden of hyperlipidemia is on the rise globally especially in many low-income countries like Uganda. Management of this metabolic disorder mainly involves dietary and behavioral therapies, which are often met with poor results as they require time and discipline from the patients. The chemotherapeutic options available are expensive, have many side effects and are rarely available to the average citizen. Thus, an alternative effective remedy which is readily available and cheap is needed to combat the problem of hyperlipidemia. This study sought to establish the effect of the mixture of Allium cepa extract and Camellia sinensis extract on the serum lipid profile of the male Wistar rats. Allium cepa and Camellia sinensis mixture in a ratio of 3:7 had the highest antioxidant activity. It reduced body weight, total cholesterol, triacylglycerides, LDL-cholesterol and increased HDL, and in addition it had no toxicity to the liver of the animal models used. It has thus been recommended as a potential therapy for hyperlipidemia and its associated complication of liver toxicity. A pharmaco-kinetic study regarding the interaction of antioxidants for combinations of Allium cepa and Camellia sinensis extracts in different ratios should be conducted to understand the cause of synergism and antagonism.

Association between maternal lipid profile and gestational diabetes mellitus

Background: Dyslipidemia is the third component of metabolic syndrome and is a wellknown cardiovascular risk factor. However, the association of dyslipidemia with gestational diabetes mellitus is still a subject of ongoing research in Nigerian obstetric populations.Objective: To determine the relationship between second trimester maternal fasting plasma lipid constituents and gestational diabetes mellitus.Methods: This was a prospective nested case control study that enrolled 288 pregnant women out of which 36 women with GDM (cases) where matched with 72 without GDM (controls) following results of oral glucosetolerance testing and plasma fasting lipid profiles done between 24 28 weeks. The patients were followed up until delivery to document maternal and fetal outcomes. Data was analyzed using Statistical Package for Social Sciences (SPSS). Categorical variables were presented in percentages while continuous variables were expressed as means (±Standard Deviation). Student ttest and Chisquare test or Fishers exact test were used for comparing variables between the two groups. A value of <0.05 at 95%confidence interval was considered statistically significant.Results: The overall mean plasma lipid levels for the four lipid constituents in the study population were 187.9mg/dL, 163.5mg/dl, 49.1mg/dL and 108.1mg/dL for TC, TG, HDLc and LDc respectively. The mean plasma triglyceride was significantly higher in cases compared to the controls: 187.0±67.7mg/dL vs. 151.7±66.4mg/dL, (p = 0.01). Abnormaltriglyceride was significantly associated with GDM (AOR:4.8, 95% CI (1.6-14.4), (p= 0.005).Conclusion:Maternal dyslipidemia (abnormal triglyceride) was shown to be significantly associated with GDM in this study and it appeared to be causally related

Relationship between magnesium and lipids in patients with diabetes mellitus

Introduction: Non-communicable diseases, especially cardiovascular diseases (CVD), have become more prevalent across the world, more so in developing countries. Novel methods in the management of CVD risks in patients with diabetes mellitus, type 2 (DM2) requires constant attention and an ever-evolving approach. The role of magnesium supplementation in the management of CVD has been described, but the relationship between serum magnesium (Mg) and the lipid subsets have had conflicting results in different population groups. Methods: A cross-sectional study was performed by collecting data on patients with DM2 from a specialised diabetes clinic at Edendale Hospital, Pietermaritzburg, KwaZulu-Natal, South Africa, between July 1, 2015 and June 30, 2016. Lipid subsets (total cholesterol [TC], high-density lipoprotein cholesterol [HDL], low-density lipoprotein cholesterol [LDL] and triglycerides [TG]), age, sex and Mg were recorded for analysis. Results: A total of 495 clinical data sheets were analysed. The majority of participants were female (73.45%) with a mean age of 56.97 years. A statistically significant, positive, linear relationship was found between Mg and TC (R= 0.11;p= 0.01) as well as Mg and LDL R= 0.14;p= 0.001), but not between Mg and HDL (R= 0.02;p= 0.66) and Mg and TG (R= 0.01;p= 0.82). Discussion: The results of this study are similar to findings by a group of researchers in China and differ when compared with studies observing Caucasian patients. It is plausible that intrinsic ethnic differences in lipid metabolism and the various ways in which magnesium requiring enzymatic processes are utilised may be responsible for the results found in the present study population versus those found in Caucasian study participants in other countries. More research is required to determine the effect of magnesium supplementation and CVD outcomes in the present study population

Oxidative stress and lipid profile among hypertensive patients at a tertiary centre in Kano, Northwest, Nigeria

Background: Hypertension as a global public health challenge is a major risk factor for cardiovascular (CVD) and coronary heart diseases (CHD) because of its chronic sequelae. It is accompanied by dyslipidemia and oxidative stress leading to increase in lipid peroxidation. This study aimed to measure the fasting serum lipid profile and malondialdehyde (MDA) and determine the atherogenic index as well as the cardiovascular risk ratio among hypertensive patients in Kano, Nigeria. Patients and Methods: Two hundred subjects (100 hypertensive patients vs. 100 normotensive controls) were recruited for the study. The fasting serum lipid profile and MDA were assayed using routine laboratory methods. Lipid ratios that predict and identify an individual's increased risk for cardiovascular diseases were then determined from the results of the profile. Results: The serum total cholesterol (7.0±0.5 vs 4.1±0.4 mmol/L), triglycerides (2.9±0.2 vs 2.0±0.3 mmol/Lg/dl), LDL cholesterol (3.8±0.4 vs 2.6±0.4 mmol/L), VLDL cholesterol (3.0±0.2 vs 2.1±0.2 mmol/L) and MDA (TBARS) (9×10-5±1.4×10-5 vs 3×106±0.9×10-6 mol/l) were significantly (p<0.05) increase in hypertensive patients compared to normotensive controls. HDL cholesterol was significantly higher (p<0.05) in normotensive controls compared to hypertensive patients (31.4±8 vs 23.9±6 mg/dl). A statistically significant (p<0.05) positive correlation was observed between LDL cholesterol and MDA only. Both the atherogenic index (AI) ratio and the CardioRisk ratio were significantly higher in Hypertensives than Normal controls (10.4 vs 4.1; 11.7 vs 5.1 respectively). Conclusion: This study demonstrated an increased occurrence of atherogenic lipid profile and oxidative stress among hypertensive patients. It further showed a strong correlation between dyslipidaemia and oxidative stress. Therapeutic lifestyle changes and use of statins should be considered an integral part of the treatment for hypertensive patients in Nigeria

Plasma Micronutrients (magnesium, zinc, selenium) Status and Lipid Profile in Type II Diabetes Mellitus Patients in Sagamu, Southwestern Nigeria

Background: Diabetes mellitus (DM) is a group of metabolic disorders characterised by hyperglycemia with secondary derangements in micronutrient status. Various studies had given conflicting reports of increased or decreased levels of micronutrients in Type II DM.Objective: To measure the plasma micronutrient levels and lipid profile in adults with Type II DM.Method: Plasma magnesium, zinc and selenium levels were measured among 100 subjects comprising 50 people with DM (age range 36-70 years) and 50 control subjects without DM (age range 29-70 years). The anthropometric parameters were measured; fasting blood glucose, plasma cholesterol, triglycerides, and high-density lipoprotein cholesterol, micronutrients (magnesium, zinc and selenium) levels were also measured using standard methods.Result: There were statistically significant (p < 0.05) higher plasma glucose, blood pressure (systolic and diastolic), LDLC, and lower levels of plasma magnesium, zinc, selenium, HDLC levels among the patients with DM (cases) compared with the normal control subjects. No significant difference was observed in the plasma total cholesterol and triglyceride between the two groups. A significant negative correlation was found between the plasma levels of the trace metals (magnesium, zinc and selenium) and triglycerides (r = - 0.36, r = - 0.43, r = - 0.51 respectively).Conclusion: Plasma levels of magnesium, zinc and selenium are reduced in Type II DM with associated hyperglycaemia-driven dyslipidaemia

Comparaison des effets nutritionnels de l'oléine de palme (huile de palme raffinée) à ceux de l'huile d'olive

Objectif : cette étude avait pour objectif de comparer les effets nutritionnels de l'oléine de palme à ceux de l'huile d'olive chez des rats.Méthodes : il s'agissait d'une étude expérimentale réalisée chez des rats Wistar mâles nourris avec un régime contenant 30% de lipides (oléine de palme et huile d'olive). Les rats avaient un libre accès à la nourriture et à l'eau. Après 12 semaines d'expériences, les animaux ont été sacrifiés et le sang aortique a été prélevé. Le plasma obtenu après traitement a été séparé en aliquotes qui ont servi au dosage des paramètres du profil lipidique (cholestérol total, triglycérides et HDL cholestérol); des paramètres du stress oxydant (SOD, GPx, TBARS, Thiols); de l'interleukine-6 et des transaminases (ALAT et ASAT).Résultats : Aucune différence significative n'a été observée entre l'huile d'Olive et l'Oléine de palme concernant les taux plasmatiques d'interleukine-6, de cholestérol total, de triglycérides, de HDL cholestérol, de GPx, des TBARS et des thiols. La consommation d'huile d'Olive a augmenté de façon significative l'activité de la SOD (p=0,0242) et l'activité de l'ALAT (p=0,0199).Conclusion : Cette étude a montré que la consommation de l'oléine de palme induit un profil lipidique non athéromateux et améliore le statut antioxydant

Lipid profile in HIV/AIDS patients in Nigeria

Introduction: Alterations of serum lipid profiles have been reported widely among Human Immuno deficiency Virus (HIV) positive patients on Highly Active Anti Retroviral Therapy (HAART). However; there are few data on serum lipid profile among treatment na?ve HIV positive patients in our environment. Objectives: To describe the pattern of lipid profile among treatment na?ve HIV positive patients and changes following HAART initiation. Methods: One hundred and thirty HIV positive patients seen in HIV center in an urban area in Nigeria and 44 matched individuals were recruited. Data were collected on socio demographic characters; baseline lipid profiles and CD4 count. Values of lipid parameters were retrieved after 12 months on HAART. Results: The mean Low density lipoprotein(LDL) was 2.26+ 0.9 mmol/l among the test group compared with 0.96+0.39mmol/L among the control ;p value =0.000 .The mean High density lipoprotein (HDL) was also significantly lower;0.8+ 0.6mmol/L reaching a dyslipidemic level; in the HIV positive group than the control; p value = 0.00. Tuberculosis /HIV co infected patients had a significantly elevated mean LDL; p=0.002. Conclusion: Abnormality of serum lipid is common among treatment na?ve HIV patients seen in Nigeria. The NNRTI regimen is associated with elevation of HDL and some stabilization of TC and TG

Serum lipids profile of untreated hypertensive patients in Port Harcourt, Nigeria

Background: Hypertension is the commonest non-communicable disease with variable prevalence rates in different parts of the world. Dyslipidaemia is associated with and predisposes to hypertension and hence increases the risk of cardiovascular disease. Aim: To determine the lipid profile in newly diagnosed hypertensive patients and compare them with age, sex and body mass index (BMI) of matched healthy non-hypertensive controls. Methods: A prospective descriptive study of newly diagnosed and treatment naive hypertensive patients. Healthy non-hypertensive adult Nigerians, who gave informed consent, consisting mainly of hospital staff and relatives of patients, matched for sex, age and BMI were recruited as controls. Results: A total of 89 patients, 42 females and 47 males and 87 healthy adults matched for age, sex, and body size were recruited as controls. Mean age of hypertensive subjects was 42.6±9.3 years and mean age for the control subjects was 41.5±4.5 years. The mean systolic blood pressure in the hypertensive subjects was 177.6±20.1 mmHg and mean diastolic blood pressure was 110.9 ±9.9 mmHg. The mean BMI in the hypertensive patients was 28.7±4.2 kg/m2, while the controls had mean BMI of 28.2±4.0 kg/m2 (P=0.5178). The mean total cholesterol (TCH) was 5.3±1.1 mmol/l in the study subjects and 4.7±0.95 mmol/l in the controls (P =0.0002). The mean low density lipoprotein cholesterol 250 in the study subjects was 4.3±1.1 mmol/l and 3.6±0.9 mmol/l in the control group (P=0.000054), while the mean triglyceride in the subjects was 1.3±0.3 mmol/l and 1.0±0.3 mmol/l in the controls (P=0.0000). Conclusion: Newly diagnosed hypertensives have significantly higher serum cholesterol levels than non-hypertensives of comparable age, sex and body size

Profil lipidique sous contraception orale combinee : a propos de 120 clientes de deux centres a Abidjan (AIBEF et CHU de yopougon)

Le risque vasculaire demeure la principale preoccupation des prescripteurs de pilules oestroprogestatives.Ce risque a fait l'objet de peu d'etude en Afrique notamment en Cote d'Ivoire. C'est pourquoi nous avons initie ce travail.OBJECTIF: Evaluer le risque vasculaire chez les utilisatrices au long cours de pilules oestroprogestatives en milieu ivoirien.METHODOLOGIE : Il s'agit d'une etude transversale portant sur les variations du profil lipidique chez 120 utilisatrices de pilules par rapport aux non-utilisatrices. Les clientes ont ete recrutees au CHU de Yopougon et au centre AIBEF de Yopougon. Nous avons dose les taux de cholesterol total; de ses fractions HDL cholesterol; LDL cholesterol et les triglycerides.RESULTATS: Nous avons note une baisse significative du taux de HDL cholesterol avec une nette augmentation de l'indice d'atherogenicite (d'environ 60pour cent) chez les utilisatrices par rapport aux non-utilisatrices. Nous n'avons pas note de modifications significatives des taux de cholesterol total; du LDL cholesterol et des triglycerides.Cette etude a demontre un risque atherogene evident chez les utilisatrices de pilules combinees. Ce risque lie a la duree d'utilisation de la pilule est d'autant plus important qu'il s'agisse de pilules de premiere generation normodosees

Aspects de la perturbation du bilan nutritionnel au cours du SIDA a Brazzaville

Deux cent malades des deux sexes; atteints de SIDA et hospitalises au CHU de Brazzaville pour diverses affections associees; sont etudies au plan de leur bilan nutritionnel evalue par des parametres anthropometriques; proteiques et lipidiques (index de masse corporelle; albumine; transferrine; retinol-binding protein; transthyretine; apolipoproteine A1; apolipoproteine B; cholesterol total; HDL-cholesterol; LDL-cholesterol; phospholipides; triglycerides). Les resultats obtenus sont compares a ceux obtenus chez soixante dix temoins seronegatifs donneurs de sang. Ces resultats montrent chez les malades atteints de SIDA; une diminution statistiquement significative de l'index de masse corporelle et des concentrations seriques de tous les parametres; a l'exception des triglyceriques et de l'apolipoproteine B

Etude de la prevalence des troubles lipidiques au sein d'une population saine a Cotonou (Benin)

Sur une population rigoureusement selectionnee; indemne de tout facteur de risque en rapport avec les parametres du bilan lipidique de routine pratique a Cotonou; les auteurs ont determine la prevalence des dysfonctionnements du metabolisme des lipides. Il est important de parfaire ce travail par le dosage; aujourd'hui possible localement; des apolipoproteines et des lipoparticules qui sont des marqueurs plus sensibles et plus fiables de l'atherosclerose (7; 10; 13). Seule une etude multicentrique; bien conduite; peut permettre de faire le point de la question en Afrique afin de determiner le risque encouru par les populations et de moduler la conduite a tenir devant les depassements anormaux des lipides a potentialite atherogene chez l'Africain
