Evaluation of Some Liver Enzymes in HIV/AIDS Patients on Antiretroviral Therapy in University of Abuja Teaching Hospital, Nigeria

Background: Hepatoxicity is a major complication and side effect of antiretroviral therapy (ART). Unfortunately, such studies in this area of evaluating the adverse drug reaction of ART on the liver hepatocytes are only few in number in Nigeria.Objective: To determine the levels of some liver enzymes in HIV/AIDS patients on antiretroviral therapy (ART) and as well evaluate their impact on liver hepatocytes.Methods: This is a hospital-based case-control study. A total of 153 subjects were recruited in the study, and they were divided into three groups: the control group (which consist of apparently healthy subjects), the study group 1 (consist of HIV positive subject not on ART), and study group 2 (consist of HIV/AIDS patients on ART). The liver enzymes Alanine amino Transferase (ALT), Asparate amino Transfarase (AST) and Alkaline Phosphatase (ALP) were determined using enzyme linked spectrophotometric assay methods, according to the manufacturer’s specifications.Results: The mean standard deviation (SD) of ALT and AST activity of the study group 1 showed significant differences when compared with that of the control group P<0.001, but the ALP has no significant differences P>0.05. In Study group 2, (HIV/AIDS patients on ART) showed significant differences of P<0.001 in ALT, AST and ALP.Conclusion: Some liver enzymes were elevated in subjects on antiretroviral therapy; this elevation could be due to hepatotoxicity of the (ART) used by the HIV/AIDS patients on the liver hepatocytes.International Journal of Human and Health Sciences Vol. 08 No. 02 Apr’24 Page: 126-131

Greenness appraisal and development of validated spectrophotometric methods for assay of amprolium: Comparative study using Analytical Eco-Scale, GAPI, and AGREEmetric approaches

Intestinal coccidiosis is a serious parasitic disease in poultry. Amprolium hydrochloride(AMP) is widely used for the treatment and prevention of coccidiosis. Three simple and green spectrophotometric methods have been developed for assay of AMP in bulk powder and in dosage form. The first method relies on measuring the first derivative (D1) spectrum at Δλ= 3 nm of AMP. This D1 spectrum possesses a characteristic peak at 234 nm. The second method relies on measuring the difference spectrophotometry (ΔA) and its first derivative (ΔD1) spectra of the drug solutions in 0.1 N HCl against the corresponding solutions in 0.1 N NaOH. The value of amplitudes of ΔA and ΔD1 (∆λ = 3 nm) were measured at 248 and 240 nm, respectively. The third method involves a colorimetric reaction with KMnO4 in alkaline medium and measuring the colored product at 610 nm. The developed methods were validated in accordance with ICH guidelines and evaluated for greenness using three greenness metrics; Analytical Eco-Scale (AES), Analytical GREEness calculator (AGREE), and Green Analytical Procedure Index (GAPI). All proposed methods showed excellent simplicity as they don't require sophisticated instrumentation or tedious analytical procedure steps.

IN-VITRO ANTI-INFLAMMATORY EVALUATION OF METHANOL AND BUTANOL EXTRACTS OF AVOACADO PEAR (PERSEA AMERICANA MILL) FRUIT PEEL

Inflammatory diseases such as arthritis, rheumatoid or non-rheumatoid joint inflammations are dominant among people all around the world. Plant-derived anti-inflammatory drugs are widely used against these disease conditions. This study investigated the in-vitro anti-inflammatory activity of the aqueous methanol and butanol extracts of Persea americana fruit peel. Three different concentrations of test samples: 10, 20 and 40 mg/ml from the concentrated methanol extract (ME) and butanol extracts (BE) were evaluated in vitro by albumin denaturation, heat induced hemolysis, anti-proteinase action, anti-lipooxygenase spectrophotometric assay methods using aspirin as a reference drug. Results showed that at sample concentrations of 10, 20 and 40 mg/ml, the inhibition of albumin denaturation by the ME and BE were in the range 26.826-51.471 % and 40.329- 54.797 % respectively. The inhibition of heat-induced haemolysis by ME at the same concentrations was in the range 30.252-44.727% and 34.52-49.897% for BE. Anti-proteinase inhibitory activity for ME was within the range of 17.073-52.1 20% while 31 .781-37.01 4% was for BE. In all four assays, the BE elicited a relatively higher inhibitory activity than the ME. These suggest that the fruit extract possesses anti-inflammatory properties which may be attributed to the occurrence of bioactive compounds in the fruit peel.

UV Spectrophotometric and UPLC assay methods for the determination of Palbociclib in bulk and Tablet Dosage Form

The goal of this study was to create a sensitive and reliable UV-spectrophotometric and reverse phase liquid chromatographic method for determining Palbociclib in bulk and pharmaceutical dosage forms. The current UV approach uses methanol and phosphate buffer as a solvent to evaluate absorption at a maximum wavelength of 220nm. Waters Acquity BEH C18 (2.1 x 50mm, 1.7µm) UPLC column with Empower 2 was used in the UPLC procedure. The mobile phase was made up of 50:50 (v/v) methanol and phosphate buffer.The drug obeyed Beer Lambert's law in the UV technique in the concentration range of 1-70µg/ml with a regression coefficient of 0.999. The linearity level in the UPLC technique was 1-100µg/ml. In the validation investigation, the developed UV and UPLC procedures were successful. For the UPLC and UV methods, the percentage purity of the marketed dosage form of Palbociclib was found to be 98.76 percent and 98.84 percent, respectively. The percent RSD of all validation parameters investigated, as suggested by the ICH recommendations, was determined to be less than 2 in both techniques. The two methods established for determining Palbociclib in bulk and tablet doses were found to be accurate, simple, and validated.

SPECTROPHOTOMETRIC DETERMINATION OF AMISULPRIDE IN TABLETS BY DIAZOTIZATION COUPLING REACTIONS

A simple and sensitive spectrophotometric methods for assay of amisulpride in pure form and tablets is achieved. Both methods involves the diazotization of amisulpride with nitrite in an acidic medium to produce the corresponding diazonium salt, followed by either coupling with iminodibenzyl (IDB) in acidic medium to give a violet azo dye which showed maximum absorption at 558 nm (method A) or coupling with 7-iodo-8-hydroxyquinoline-5- sulfonic acid (IHQS) in alkaline medium to produce a red azo dye which show maximum absorbance at 522 nm (method B). The two methods have been applied successfully to determine of amisulpride in tablets and also evaluated by applying the standard addition technique

Comparison of the optimized direct spectrophotometric serum prolidase enzyme activity assay method with the currently used spectrophotometric assay methods and liver fibrosis indexes to distinguish the early stages of liver fibrosis in patients with chronic hepatitis B infection.

The aim of this study was to optimize the currently used direct spectrophotometric serum prolidase enzyme activity (SPEA) assay method and compare its diagnostic accuracy with current precipitation and direct spectrophotometric assay methods, AST-to-ALT ratio, age platelet index, AST-to-platelet ratio index, cirrhosis discriminate score, Doha score, FIB-4, FibroQ, fibrosis index, Goteborg University Cirrhosis Index , King's score, and Pohl score for distinguishing Ishak F0 from F1-F3 in patients with chronic hepatitis B (CHB) infection. Liver biopsy results from 112 patients were included in this study. The SPEA values were 529(292-794) U/L, 671(486-927) U/L, and 1077(867-1399) U/L with the precipitation, current, and optimized direct spectrophotometric assay methods, respectively. According to multivariate logistic regression analysis optimized direct spectrophotometric SPEA was the only statistically significant parameter to predict the early stages of liver fibrosis. Optimized direct spectrophotometric SPEA assay method could be used to distinguish early stages of liver fibrosis in patients with CHB infection instead of the currentlyused spectrophotometric SPEA assay methods and other evaluated liver fibrosis indexes.

Visible spectrophotometric assay for characterization of ω-transaminases

Omega-transaminases (ω-TAs) have attracted considerable interest for their use in asymmetric synthesis of chiral amines with a high degree of optical purity and yield. The rapid evaluation of the characteristics of newly identified or engineered ω-TAs is important for industrial applications. In this study, a visible spectrophotometric assay was developed for rapid quantitative determination of ω-TA activities based on the transamination of 2-(4-nitrophenyl)ethan-1-amine to generate a red product (E)-N-(4-nitrophenethyl)-2-(4-nitrophenyl)ethen-1-amine. After various co-solvents were evaluated, dimethyl sulfoxide (DMSO) was considered optimal because the red product exhibits good solubility and retains its original color. The red product dissolved in DMSO has its highest absorbance at 465 nm, and its concentration has a good linear relationship with the absorbance. A spectrophotometric assay was established and validated using conventional HPLC analysis (<10% divergence). This method was then used to characterize an ω-TA from thermophilic Geobacillus thermoleovorans and an ω-TA obtained from the metagenome of a soda lake. The results demonstrated that ω-transaminase enzymatic properties could be characterized simply, rapidly, and at low cost, using this newly established visible spectrophotometric assay method.

In Vitro Combined Effect of Annona Senegalensis and Piliostigma Thonningii Leaf Extracts on Alpha Amylase Activity

Background: Diabetes mellitus (DM), a group of metabolic disorders characterised by hyperglycaemia, has been attributed to increased activity of α-amylase, one of the key enzymes in carbohydrate metabolism. Alpha amylase inhibition can potentially control postprandial hyperglycaemia, hence significant in the management of diabetes mellitus, especially type 2. Acarbose, the proven α-amylase inhibitor, has been associated with several side effects. Plants used in traditional medicine represent a valuable source in the search for an alternative. The study aimed at determining the combined effect of Piliostigma thonningii and Annona senegalensis leaf extracts on alpha amylase activity. Methodology: Mortar and pestle were used to crush the leaves into powder. The fine powder was dispensed in distilled water. Percolation was used to filter the crude extract, evaporated in a water bath at 65 0C to concentrate the extract then reconstituted. Spectrophotometric assay method was used for alpha amylase activity at 540 nm. Results: The results of the study showed that A. senegalensis inhibited α-amylase by 27%, 32% and 34% at 15, 30 and 45 minutes respectively. P. thonningii exhibited inhibitory effects on α-amylase by 25%, 27% and 37% at 15, 30 and 45 minutes respectively. The combined inhibitory effects of A. senegalensis and P. thonningii on α-amylase were 28%, 37% and 62% at 15, 30 and 45 minutes respectively which are significantly different (p &lt;0.05) from that of the positive control, acarbose (71% at 45 minutes) Conclusion: This study revealed the increased strength to inhibit alpha amylase enzyme by a combination of A. senegalensis and P. thonningii and a proportional increase in the inhibitory effect with increase in incubation time than their individual potential to inhibit alpha amylase.

Do different lipid components accelerate the pathogenesis and severity of Diabetic Retinopathy?

BackgroundTo assess the association of lipid and lipid-derived toxic molecules in pathogenesis and severity of diabetic retinopathy (DR) in type 2 diabetes mellitus (T2DM).MethodsThe present cross-sectional study included 14 healthy individuals (HC) without T2DM, 22 T2DM subjects without DR (DNR), 24 T2DM subjects with mild non-proliferative DR (MNPDR), and 24 T2DM subjects with high-risk proliferative DR (HRPDR). All subjects underwent plasma and vitreous analysis for estimation of total lipid (TL), free fatty acid (FFA), lipid peroxides (LPOs) like malondialdehyde (MDA), 4-Hydroxy-noneal (HNE), the advanced lipoxidation end product (ALE) like Hexanoyl-lysine (HLY) and vascular endothelial growth factor (VEGF) following standard spectrophotometric and enzyme-linked immunosorbent assay (ELISA) methods respectively.ResultsThe concentration of TL, FFA, markers of lipid peroxidation and lipoxidation as well as VEGF in plasma and vitreous were found to be significantly elevated stepwise inT2DM subjects (HRPDR > MNPDR > DNR) compared to healthy controls (HC).Further, plasma conventional lipid components like total cholesterol (TCH), low density lipoprotein cholesterol (LDL-C) and triglycerides (TG), FFA and TL showed their significant positive correlations with vitreous level of different LPOs, ALE and VEGF in the DR group.ConclusionTotal lipid and lipid-derived detrimental biomolecules ultimately result in increased secretion of VEGF and thus not only add as associated mediators in the pathogenesis of DR, these also accelerate the severity of microangiopathy in T2DM.

3-Indolepropionic acid prevented chlorpyrifos-induced hepatorenal toxicities in rats by improving anti-inflammatory, antioxidant, and pro-apoptotic responses and abating DNA damage.

The application of chlorpyrifos (CPF), an organophosphorus pesticide to control insects, is associated with oxidative stress and reduced quality of life in humans and animals. Indole-3-propionic acid (IPA) is a by-product of tryptophan metabolism with high antioxidant capacity and has the potential to curb CPF-mediated toxicities in the hepatorenal system of rats. It is against this background that we explored the subacute exposure of CPF and the effect of IPA in the liver and kidney of thirty rats using five cohort experimental designs (n = 6) consisting of control (corn oil 2mL/kg body weight), CPF alone (5mg/kg), IPA alone (50mg/kg), CPF + IPA1 (5mg/kg + 25mg/kg), and CPF + IPA2 (5mg/kg + 50mg/kg). Subsequently, we evaluated biomarkers of hepatorenal damage, oxidative and nitrosative stress, inflammation, DNA damage, and apoptosis by spectrophotometric and enzyme-linked immunosorbent assay methods. Our results showed that co-treatment with IPA decreased CPF-upregulated serum hepatic transaminases, creatinine, and urea; reversed CPF downregulation of SOD, CAT, GPx, GST, GSH, Trx, TRx-R, and TSH; and abated CPF upregulation of XO, MPO, RONS, and LPO. Co-treatment with IPA decreased CPF-upregulated IL-1β and 8-OHdG levels, caspase-9 and caspase-3 activities, and increased IL-10. In addition, IPA averts CPF-induced histological changes in the liver and kidney of rats. Our results demonstrate that co-dosing CPF-exposed rats with IPA can significantly decrease CPF-induced oxidative stress, pro-inflammatory responses, DNA damage, and subsequent pro-apoptotic responses in rats' liver and kidneys. Therefore, supplementing tryptophan-derived endogenous IPA from exogenous sources may help avert toxicity occasioned by inadvertent exposure to harmful chemicals, including CPF-induced systemic perturbation of liver and kidney function.

Reusable alcohol oxidase-nPtCu/alginate beads for highly sensitive ethanol assay in beverages.

Nanozymes (NZs) are nanoparticles that mimic the catalytic properties of natural enzymes. The present work aimed to obtain effective peroxidase mimetics (PO-like NZs), to characterize their morphological properties, estimate the kinetic parameters of NZs and evaluate the prospects of their application in analysis of ethanol. Herein, we have proposed a convenient spectrophotometric method for ethanol assay using reusable alginate beads enriched with alcohol oxidase (AO) and nanoparticles of PtCu (nPtCu) as PO-like NZs, and 3,3′,5,5′-tetramethylbenzidine (TMB) as a chromogen. The linear range for the proposed nPtCu–AO/alginate beads/TMB-based method is from 0.01 mM to 0.15 mM with a limit of detection of 3.3 μM ethanol. The method is used for the quantitative determination of ethanol in alcoholic beverages. The obtained results proved to be in a good correlation with the enzymatic reference method. These results highlight the potential of the nPtCu with PO-like activity in bioanalytical applications. The proposed method, being sensitive, economical and suitable for routine and micro-volume formats, can be used in clinical diagnostics for the detection of ethanol.

New validated Spectroscopic methods were developed to assay Bromhexine Hydrochloride and its active metabolite Ambroxol Hydrochloride separately in pure form and pharmaceutical formulations. The spectrophotometric assay (method I) shows complex formation between each of the drugs and Eosin Y at 540nm at pH 3.6 and 3.4mL of 4×10-4M Eosin for Bromhexine and Ambroxol. The Spectrofluorimetric assay (method II) depends on quenching eosin native fluorescence by the studied drugs, which measured at 540nm after excitation at 302nm. The spectrophotometric absorbance-concentration plot is rectilinear over the ranges (1.0-5.0) and (1.0-10.0) μg/mL for bromhexine and ambroxol with LOD of 0.31 and 0.14μg/mL and LOQ of 0.94 and 0.42μg/mL for the two drugs respectively. The fluorometric-concentration plot is linear along the range (1.0-5.0) μg/mL and (1-10) μg/mL for the two drugs respectively with LOD of 0.13μg/mL and 0.22μg/mL and LOQ of 0.4μg/mL and 0.65μg/mL for the two drugs, respectively. Developed assays have been validated in agreement with ICH recommendations and they were used in the analysis of commercial drug formulations containing the two mucolytic drugs and the results were matching with those obtained by the comparison method.

Different spectrophotometric methods manipulating ratio spectra for the assay of hydrocortisone acetate and clioquinol in their topical preparation

Simple and precise spectrophotometric methods for quantitative assay of a mixture of hydrocortisone acetate (HCA) and clioquinol (CL) were developed and validated through different mathematical manipulation pathways. The developed methods utilized ratio spectra for resolving binary mixtures including absorbance subtraction, ratio subtraction coupled with spectrum subtraction, constant multiplication, constant value, and derivative ratio. The proposed methods were proved to be specific by analysing the laboratory-prepared mixtures and were applied for the assay of topical preparation successfully. The methods were validated using ICH guidelines where accuracy, repeatability and intermediate precision were within the acceptable limits. The linearity range was found to be 2-22 for HCA and 1.5-7 µg/mL for CL in all proposed methods and 2-7 µg/mL for HCA and CL in absorbance subtraction method through using a unified regression equation. The findings were statistically evaluated with respect to the official and reported methods, demonstrating that there was no significant difference.

Chlorella vulgaris is an effective supplement in counteracting non‐alcoholic fatty liver disease‐related complications through modulation of dyslipidemia, insulin resistance, and inflammatory pathways

This study was aimed to investigate the effect of microalgae Chlorella vulgaris (C. vulgaris) on nonalcoholic fatty liver disease (NAFLD)-related complications induced by high-fat diet (HFD). Fifty adult male rats were divided into six groups. Control group and HFD group treated with or without C. vulgaris 5% and 10%. Biochemical parameters in serum were measured by spectrophotometric and enzyme-linked immunosorbent assay (ELISA) methods. The relative gene expression levels of Tumor Necrosis Factor-alpha (TNF-α), NF-kappa B (NF-ƙB), and p38 Mitogen-Activated Protein Kinases (p38 MAPK) in the liver were assessed by using quantitative real-time PCR, while the protein levels of NF-ƙB and TNF-α in the liver homogenate were determined by ELISA. The effects of HFD significantly were reversed by C. vulgaris, especially at a 10% dose. Therefore, it can be concluded that C. vulgaris therapeutically could be useful to improve NAFLD and its complications. PRACTICAL APPLICATIONS: It is established that NAFLD is associated with the resistance to insulin, dyslipidemia, and inflammation. Accordingly, modulating of these conditions may be useful in the management of NAFLD. Our results showed the effectiveness of C. vulgaris against NAFLD-related complication through the alleviating insulin resistance, dyslipidemia and also down-regulation of inflammatory genes in p38 MAPK/TNF-α/NF-ƙB pathway. The results of our study may be useful for scientist to prepare an effective supplement from C. vulgaris to overcoming NAFLD-related complications.

The proposed methods are simple, selective, and sensitive in the quantification of REB and DER. These methods were validated according to International Conference on Harmonization guidelines. Statistical analyses performed on the findings from the suggested methods and those obtained from reported methods revealed high accuracy and good precision. The developed and validated methods are useful for quality control assay in routine analyses. First derivative, second derivative, derivative ratio, and mean centering methods for quantification of REM and DER. These methods are useful for analysis of REB in pharmaceutical dosage form.

Plasma hemoglobin: A method comparison of six assays for hemoglobin and hemolysis index measurement

Plasma hemoglobin (Hb) is measured for assessment of in vivo and in vitro hemolysis. The objective of the present investigation was to conduct a method comparison of five quantitative and one semi-quantitative Hb and H-index (hemolysis index) assays to evaluate their performance measuring plasma Hb in clinical specimens. One hundred and fourteen clinical specimens previously tested for plasma Hb using a laboratory-developed spectrophotometric assay were also tested for Hb using a HemoCue Plasma/Low Hb assay (azide methemoglobin), a laboratory-modified Pointe Scientific Hb assay (cyanmethemoglobin), tested for H-index measurements using a Roche cobas c501, an Abbott Architect c8000, and a semi-quantitative (binned) H-index measurement on a Beckman AU5800. The reference result was defined as the median Hb score (median of all Hb or H-index results). The laboratory-developed spectrophotometric Hb assay and Roche H-index methods mostly closely matched the median Hb score across all data, as well as for lower range median Hb score results ≤2.0g/L. Two-way frequency table analysis using an Hb (or H-index) cutoff of 0.5g/L (or 0.5 H-index units) was then performed to compare methods to the median Hb score cutoff. The Beckman method had the highest accuracy at this cutoff, the Roche and Abbott methods had the highest positive predictive value (PPV), and the Beckman, HemoCue, and Pointe methods had the highest negative predictive value (NPV). Plasma Hb and H-index results vary by method. Laboratories should evaluate the performance characteristics of their respective assays when considering adoption of spectrophotometric or chemical methods for plasma Hb assessment.

Assessment of Plasma Sodium to Potassium Ratio, Renal Function, Markers of Oxidative Stress, Inflammation, and Endothelial Dysfunction in Nigerian Hypertensive Patients.

Background This study investigated plasma sodium/potassium ratio, markers of oxidative stress, renal function, and endothelial dysfunction in hypertensive Nigerians. Materials and Methods Five hundred forty-nine volunteers consisting of three hundred and twenty-four hypertensive and two hundred twenty-five controls participated in this study. Blood samples were collected from the participants and were analyzed for electrolytes, markers of oxidative stress, endothelial dysfunction, renal function, and inflammation, using ion-selective electrodes, spectrophotometric, and enzyme-linked immunosorbent assay methods, respectively. Results The mean systolic blood pressure, mean diastolic blood pressure, mean arterial blood pressure, and body mass index (BMI) were significantly elevated among the hypertensive group when compared with control (p < 0.001). The mean sodium increased, while potassium and bicarbonate (HCO3−) decreased (p < 0.001) in hypertensive volunteers. The sodium-potassium ratio (Na+/K+) and urea were raised (p < 0.001) in the hypertensive group when compared with the control. Glutathione, superoxide dismutase, nitric oxide (NO), and catalase were significantly reduced (p < 0.001) while malondialdehyde (MDA), high-sensitivity C-reactive protein (hs-CRP), and ferritin were raised significantly (p < 0.001) in hypertensive participants. The odds of hypertension and its complications increased (p < 0.001) with an increase in BMI, Na+/K+, hs-CRP, MDA, and ferritin and a decrease in estimated glomerular filtration rate (eGFR), glutathione, superoxide dismutase, and catalase. Conclusion An increase in Na+/K+, urea, hs-CRP, ferritin, MDA, and BMI and a decrease in eGFR, glutathione, and superoxide dismutase were associated with an increased risk of hypertension complication. Abnormal values of markers of oxidative stress, inflammation, and endothelial function could impact deleterious effects on the cardiovascular system among hypertensive Nigerians. A decreased bicarbonate possibly suggests an occult acid-base imbalance among hypertensive volunteers.
