ABSTRACT
BACKGROUND: In type 1 diabetes mellitus (T1DM), cytokines have a central role in orchestrating multicellular relations between ß-cells and immune cells. This study aims to investigate the role of interleukin (IL)-21, IL-23, and IL-2, and their association with dyslipidemia in T1DM children. METHODS: The sample population consisted of 30 healthy controls and 70 children with T1DM, the latter of which were split into two groups according to the duration of their T1DM diagnosis: recent (≤ 1 year; n = 21) and older (> 1 year; n = 49) diagnoses. RESULTS: Fasting blood sugar and glycated hemoglobin levels in all diabetic children were significantly (P < 0.001) higher, whereas levels of plasma C-peptide were markedly (P < 0.001) lower in children with T1DM compared to healthy controls. In older T1DM diagnosis children, the levels of creatinine were noticeably (P < 0.05) increased relative to healthy controls. In all diabetic children, levels of total triglyceride, cholesterol, and low-density lipoprotein were increased significantly (P < 0.001) than those of healthy controls. Furthermore, the IL-21 and IL-23 mRNA expressions of all children with T1DM were elevated significantly (P < 0.001) relative to healthy controls, whereas IL-2 levels revealed a significant (P < 0.001) decrease in all diabetic children. CONCLUSION: There was a synergistic interplay between IL-21 and IL-23 with an antagonistic action of IL-2 in T1DM patients, and all three interleukins were associated with dyslipidemia in diabetic children. Importantly, therapies targeting IL-21 and IL-23 are promising targets for preventive strategies against the development of T1DM and its complications.

BACKGROUND: Incidence of diabetes has increased significantly worldwide over recent decades. Our objective was to prepare and characterize a novel nano-carrier of hesperidin to achieve a sustained release of hesperidin and to explore the potency of the novel formula as an antidiabetic agent compared to metformin in type 2 diabetic rats. METHODS: Hesperidin was loaded on MgAl-layered double hydroxide (LDH). The formula was characterized using Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), transmission electron microscopy, and dynamic light scattering. The release profile of hesperidin and MgAl-LDH-Hesperidin were studied in vitro. The parameters studied in vivo were blood glucose, glycated hemoglobin (HbA1c), insulin, lipid profile, and liver glycogen levels. We also investigated the levels of interleukin (IL)-17, tumor necrosis factor-Alfa (TNF-α), malondialdehyde (MDA), catalase, and the mRNA expression of peroxisome proliferator-activated receptor-gamma (PPARγ) and nuclear factor erythroid 2-related factor-2 (NrF2). RESULTS: There were variations in the XRD patterns and FTIR confirming the physical adsorption of hesperidin on the surface of LDH. The results indicated that the diabetic rats treated with administration of antidiabetic formula, MgAl-LDH-Hesperidin, showed a beneficial effect on the levels of blood glucose, insulin, HbA1c%, and lipid profile, comparing to diabetic control rats. The antidiabetic agent also showed a significant decrease in the levels of TNF-α, IL-17, and MDA, and an increase in the level of catalase. Marked upregulation of the expression levels of mRNA for PPARγ and NrF2 were recorded. CONCLUSION: The novel nano-hesperidin formula MgAl-LDH-Hesperidin revealed a sustained release of hesperidin and exhibited antidiabetic, antihyperlipidemic, antioxidant, and anti-inflammatory properties, and also is a promising agent for effective delivery of drugs to treat type 2 diabetes.

Omeprazole suppresses excessive secretion of gastric acid via irreversible inhibition of H+/K+-ATPase in the gastric parietal cells. Recent meta-analysis of data revealed an association between the use of proton pump inhibitors (PPIs) and increased risk of bone fractures, but the underlying molecular mechanism of PPI action remains unclear. In this study, we demonstrated that omeprazole directly influences bone metabolism using a unique in vitro bioassay system with teleost scales, as well as the in vivo model. The in vitro study showed that omeprazole significantly increased the activities of alkaline phosphatase and tartrate-resistant acid phosphatase after 6 h of incubation with this PPI. Expression of mRNAs for several osteoclastic markers was upregulated after 3-h incubation of fish scales with 10-7 M omeprazole. The in vivo experiments revealed that the plasma calcium levels significantly increased in the omeprazole-treated group. The results of in vitro and in vivo studies suggest that omeprazole affects bone cells by increasing bone resorption by upregulating expression of osteoclastic genes and promoting calcium release to the circulation. The suggested in vitro bioassay in fish scales is a practical model that can be used to study the effects of drugs on bone metabolism.

OBJECTIVES: Obese patients are at increased risk for CVD, which is the main cause of premature death and has been a major cause of disability and ill health in recent years. PTN, a natural dihydrochalcone flavonoid, has a variety of pharmacological characteristics. This article aimed to prepare PTN-NSLs to evaluate their anti-obesity activity. METHODS: Morphology, Particle size, zeta potential, UV-vis, entrapment efficiency, FT-IR spectra, and an in vitro release study of PTN-NSLs were described. PTN-NSLs were also tested for their anti-obesity properties in obese rats. The LD50 of PTN-NSLs was calculated, as was the 1/20 LD50 prepared for the treatment of obese rats. Also, the level of glycemic, oxidative stress and inflammatory biomarkers were estimated in the obese rat's model. RESULTS: The synthesized PTN-NSLs were uniform, spherically shaped, and well dispersed with no aggregation noted, with a size range of 114.06 ± 8.35 nm. The measured zeta potential value of PTN-NSLs was -32.50.8 mv. Also, the UV spectra of PTN and PTN-NSLs have strong absorption at 225 and 285 nm. Also, the LD50 of PTN-NSLs was found to be 2750 mg/kg.b.w. Moreover, administrating obese rats with PTN-NSLs resulted in improved glycemic features as well as GSH, SOD, GPx, GR, IL10, TBARs, and IL-6 levels, as well as attenuated FAS, SREBP1c, AMPK, ACO, CPT1, and OB-Rb gene expression. CONCLUSIONS: Administration of PTN-NSLs significantly attenuated the levels of glycemic, oxidative stress, and inflammatory biomarkers. The biochemical and PCR findings are aided by histological investigations. Also, the present findings imply that PTN-NSLs might be a promising pharmacological tool for the treatment of obesity-related diseases.
ABSTRACT
Atherosclerosis is an inflammatory disease characterized by the accumulation of arterial plaque. Diabetes mellitus stands out as a major risk factor for atherosclerosis. Candesartan is a potent angiotensin II receptor antagonist that enhances arterial blood flow and reduces insulin resistance. However, oral candesartan has limited activity because of its low bioavailability, water solubility, hepatic first-pass degradation, and efficacy. The current study aims to develop nasal candesartan-loaded invasome (CLI) drops to improve candesartan's permeation, release, and bioavailability as a potential treatment for diabetes-associated atherosclerosis. Design expert software was used to prepare various CLI formulations to determine the impact of the concentrations of ethanol, cineole, and phospholipid. The desirability index was used to estimate the optimized formulation composition to maximize entrapment efficiency and minimize vesicle size. The optimized formulation had a 1% ethanol concentration, a 1.5% cineole concentration, and a 2.32% phospholipid concentration. The selected optimized formulation was then tested in a rat model of diabetes and atherosclerosis to evaluate its activity. The results showed that nasal CLI drops significantly raised serum HDL levels by a ratio of 1.42 and lowered serum glucose, cholesterol, triglycerides, LDL, and VLDL levels by 69.70%, 72.22%, 36.52%, 58.0%, and 65.31%, respectively, compared with diabetic atherosclerotic rats, throwing an insight on the potential for promising anti-diabetic and anti-atherosclerotic activities. Additionally, atherosclerotic lesions were improved in rats treated with CLI, as shown in histopathology. In conclusion, the results of this investigation showed that treatment with nasal CSN-loaded invasome formulation drops prevented the initiation and progression of diabetes-associated atherosclerosis.

BACKGROUND: Elevated serum levels of MMP-13 are linked to tumor growth and metastasis, while miR-138 dysregulation is observed in breast cancer cases. The aim of this study is to investigate the expression of miR-138 and MMP-13 levels as potential biomarkers for the prognosis of breast cancer. PATIENTS AND METHOD: In this retrospective case-control study, 119 female subjects were recruited and divided into three groups. MMP-13 level was measured using Enzyme Linked Immunosorbent Assay (ELISA), while real-time PCR technique was employed to quantify miR-138 expression. RESULTS: Both non-metastatic and metastatic groups showed significantly higher levels of serum MMP-13 compared to other groups. MMP-13 levels are significantly increased among patients with advanced tumor size, lymph node metastasis, and triple-negative breast cancer cases. An inverse significant association between MMP-13 levels and response to treatment was observed. Expression of miR-138 underwent a significant down-regulation in breast cancer patients, and a statistically significant association was established between miR-138 expression and triple-negative breast cancer cases. A positive association was detected between the increase in miR-138 expression and the good response to treatment. The expression of miR-138 was inversely correlated with the MMP-13 levels. CONCLUSION: MMP-13 levels were significantly higher in breast cancer, especially in advanced cases, suggesting its role in promoting tumor invasion and metastasis. MiR-138 was down-regulated in breast cancer, especially in triple-negative breast cancer patients, rendering it a promising biomarker for triple-negative breast cancer. Modulation of miR-138 expression and MMP-13 levels may represent therapeutic targets for breast cancer.

In this study, a biodegradable poly-gamma-glutamic-acid nanopolymer (Æ-PGA NP) was investigated for its activity against clinical strains of Gram-positive (Staphylococcus aureus and Streptococcus pyogenes) and Gram-negative (Klebsiella pneumoniae and Escherichia coli), and reference strains of S. aureus ATCC 6538, S. pyogenes ATCC 19615 (Gram-positive), and Gram-negative E. coli ATCC 25922, and K. pneumoniae ATCC 13884 bacterial biofilms. The minimum inhibitory concentration (MIC) effect of Æ-PGA NP showed inhibitory effects of 0.2, 0.4, 1.6, and 3.2 µg/mL for S. pyogenes, S. aureus, E. coli, and K. pneumoniae, respectively. Also, MIC values were 1.6, 0.8, 0.2, and 0.2 µg/mL for K. pneumoniae ATCC 13884, E. coli ATCC 25922, S. aureus ATCC 6538, and S. pyogenes ATCC 19615, respectively. Afterwards, MBEC (minimum biofilm eradication concentration) and MBIC (minimum biofilm inhibitory concentration) were investigated to detect Æ-PGA NPs efficiency against the biofilms. MBEC and MBIC increased with increasing Æ-PGA NPs concentration or time of exposure. Interestingly, MBIC values were at lower concentrations of Æ-PGA NPs than those of MBEC. Moreover, MBEC values showed that K. pneumoniae was more resistant to Æ-PGA NPs than E. coli, S. aureus, and S. pyogenes, and the same pattern was observed in the reference strains. The most effective results for MBEC were after 48 h, which were 1.6, 0.8, 0.4, and 0.2 µg/mL for K. pneumoniae, E. coli, S. aureus, and S. pyogenes, respectively. Moreover, MBIC results were the most impactful after 24 h but some were the same after 48 h. MBIC values after 48 h were 0.2, 0.2, 0.2, and 0.1 µg/mL for K. pneumoniae, E. coli, S. aureus, and S. pyogenes, respectively. The most effective results for MBEC were after 24 h, which were 1.6, 0.8, 0.4, and 0.4 µg/mL for K. pneumoniae ATCC 13884, E. coli ATCC 25922, S. aureus ATCC 6538, and S. pyogenes ATCC 19615, respectively. Also, MBIC results were the most impactful after an exposure time of 12 h. MBIC values after exposure time of 12 h were 0.4, 0.4, 0.2, and 0.2 µg/mL for K. pneumoniae ATCC 13884, E. coli ATCC 25922, S. aureus ATCC 6538, and S. pyogenes ATCC 19615, respectively. Besides that, results were confirmed using confocal laser scanning microscopy (CLSM), which showed a decrease in the number of living cells to 80% and 60% for MBEC and MBIC, respectively, for all the clinical bacterial strains. Moreover, living bacterial cells decreased to 70% at MBEC while decreasing up to 50% at MBIC with all bacterial refence strains. These data justify the CFU quantification. After that, ImageJ software was used to count the attached cells after incubating with the NPs, which proved the variation in live cell count between the manual counting and image analysis methods. Also, a scanning electron microscope (SEM) was used to detect the biofilm architecture after incubation with the Æ-PGA NP. In in vivo wound healing experiments, treated wounds of mice showed faster healing (p < 0.00001) than both the untreated mice and those that were only wounded, as the bacterial count was eradicated. Briefly, the infected mice were treated faster (p < 0.0001) when infected with S. pyogenes > S. aureus > E. coli > K. pneumoniae. The same pattern was observed for mice infected with the reference strains. Wound lengths after 2 h showed slightly healing (p < 0.001) for the clinical strains, while treatment became more obvious after 72 h > 48 h > 24 h (p < 0.0001) as wounds began to heal after 24 h up to 72 h. For reference strains, wound lengths after 2 h started to heal up to 72 h.
ABSTRACT
Diabetes mellitus is a metabolic disease that raises the odds of developing stroke. Candesartan has been used to prevent stroke due to its inhibitory effects on blood pressure, angiogenesis, oxidative damage, and apoptosis. However, oral candesartan has very limited bioavailability and efficacy due to its weak solubility and slow release. The study aimed to develop a nasal formulation of candesartan-loaded liposomes containing ethanol and propylene glycol (CLEP) to improve candesartan's delivery, release, permeation, and efficacy as a potential diabetes-associated stroke treatment. Using design expert software, different CLEP formulations were prepared and evaluated in vitro to identify the optimum formulation, which. The selected optimum formulation composed of 3.3% phospholipid, 10% ethanol, and 15% propylene glycol significantly increased the release and permeation of candesartan relative to free candesartan by a factor of 1.52 and 1.47, respectively. The optimum formulation significantly reduced the infarction after stroke in rats; decreased flexion, spontaneous motor activity, and time spent in the target quadrant by 70%, 64.71%, and 92.31%, respectively, and enhanced grip strength by a ratio of 2.3. Therefore, nasal administration of the CLEP formulation could be a potential diabetes-associated stroke treatment.

To overcome the low bioavailability of lipophilic free thymoquinone (TQ), this study aims to evaluate a novel oral formula of TQ-loaded chitosan nanoparticles (TQ-CsNPs) for the effective treatment of diabetes. The XRD, FTIR, FESEM, HRTEM, and dynamic light scattering were all conducted on the prepared formula. The release pattern of TQ, cytotoxicity against MRC-5 cell line (human lung fibroblast cells), and antidiabetic activity on streptozotocin/nicotinamide (STZ/NA) rat model of diabetes were investigated. The results confirmed the formation of TQ-CsNPs with an entrapment efficiency of 75.7 ± 6.52 %, a mean Zetasizer distribution of 84.25 nm, and an average particle size of about 50 nm. After 24 h, the percentage of free TQ-cumulative release was approximately 35.8 %, whereas TQ-CsNPs showed a sustained release pattern of 78.5 %. The investigated formula was not toxic to normal lung cells, and more efficient in ameliorating the altered glycemia, dyslipidemia, inflammation, and oxidative stress induced by STZ/NA than free TQ, blank CsNPs, and metformin-HCl (as a reference drug). Additionally, TQ-CsNPs restored the normal pancreatic islets' configuration and morphometry, suggesting a potent insulinotropic action. In conclusion, the antidiabetic efficacy of TQ was improved by engaging TQ with CsNPs as an excellent nanoplatform to enhance the oral bioavailability of TQ.

OBJECTIVES: Recently, numerous studies have renewed attention to the hematologic profile in the early identification of diabetic inflammation and complications. The objective of this study was to investigate the relationship between hematologic indices abnormalities and oxidative stress among children with type 1 diabetes mellitus (T1DM). METHODS: This study included 70 children diagnosed with T1DM and 30 healthy control subjects. The children with T1DM were divided into 2 groups according to the duration of diabetes: children with newly diagnosed T1DM and children with established T1DM. RESULTS: Erythrocyte count and platelet count were decreased significantly in children with established T1DM, whereas leukocyte count and neutrophil count were increased significantly in children with newly diagnosed T1DM compared with healthy control subjects. Moreover, hemoglobin and hematocrit values revealed a significant depletion in both T1DM groups; however, values of red blood cell distribution width, mean platelet volume and platelet distribution width were significantly elevated in both T1DM groups compared with healthy control subjects. Also, microalbuminuria levels showed a significant increase in children with established T1DM, whereas lipid peroxidation biomarker (malondialdehyde) and nitric oxide levels were elevated markedly in both T1DM groups compared with the healthy group. CONCLUSIONS: The data demonstrated that the hematologic profile showed noticeable alterations in children with T1DM, and the inflammation and oxidative stress markers were contributed to the hematologic abnormalities. The results revealed that some hematologic indices can be used in the early detection of children with T1DM at risk for diabetic complications.

The clinical studies proved the adverse effect of Propranolol on sexual function. Regarding this issue, the key research question of this study was, whether the designed herbal nanohybrid formula EGCG-chitosan-alginate has an efficacy versus Propranolol, or not? The formula was optimized according to the coacervation method. Its molecular structure and characteristics were confirmed. The entrapment efficiency was determined, and the stability, as well in vitro release study was conducted. The in vivo study was conducted for 65 days. To answer the raised question, tissue weights of the testis, epididymis seminal vesicles, and prostate were determined. Oxidative stress markers as MDA and GSH were measured in testis and epididymis, while testosterone in blood serum. The semen analysis was performed. DNA damage was detected according to the comet assay procedures. Conventional pathological examination was done in special concern to testis and epididymis. The characterization results reflected the good preparation of the formula with an amorphous structure in a range of 200 nm, high stability with ZP + 57.3 mV. The calculated EE was 84.10 ± 1.19% and the release percent was 72.11 ± 0.77% for 24 hrs. All the rats increased in the weight with variations among the groups in the tissue organs. The finding exposed a significant decrease in the average of MDA in the rats' testes with a significant increase in GSH while a non-significant difference in the epididymis, in both. The testosterone, the seminal parameters, and the DNA integrity significantly increased in the nano-formula compared to propranolol. Likewise, normal pathological findings of the nano-formula in the testis and Epididymis compared to abnormal of propranolol. In total, the current research confirmed that EGCG had no toxic effects and able to promote fertility. The most important finding was the administration of EGCG either in normal or nano-form prior to propranolol alleviated the effects of propranolol. These findings reflected the protection evident of EGCG versus propranolol.

It has been reported that spinal deformity was induced in developing fish by the addition of polycyclic aromatic hydrocarbons (PAHs). To examine the mechanism of the disruption of fish bone metabolism, the effect of benz[a]anthracene (BaA), a kind of PAH, on plasma calcium, inorganic phosphorus, osteoblasts, and osteoclasts was investigated in this study. We also measured several plasma components to analyze the toxicity of BaA on other metabolisms. BaA (1 or 10 ng/g body weight) was intraperitoneally injected (four times) into nibbler fish during breeding, for 10 days, and it was indicated, for the first time, that injecting high doses of BaA to nibbler fish induced both hypocalcemia and hypophosphatemia. Furthermore, in the scales of nibbler fish treated with high doses of BaA, both osteoclastic and osteoblastic marker messengerRNA (mRNA) expressions decreased. These results are a cause of disruption of bone metabolism and, perhaps, the induction of spinal deformities. In addition, we found that total protein, metabolic enzymes in the liver, total cholesterol, free cholesterol, and high-density lipoprotein cholesterol levels significantly decreased in BaA-injected fish. These results indicate that BaA may affect liver diseases and emphasize the importance of prevention of aquatic PAH pollution.

AIMS: The present study aimed to evaluate the correlation between glycemic status and the inflammation biomarkers; leukocytes, platelets indices and interferon gamma (IFN-γ) production in type 2 diabetes mellitus (T2DM) patients regarding diabetic complications. METHODS: Study was conducted on 158 patients allocated as normal healthy subjects (50) and 108 patients diagnosed as T2DM. The diabetic patients were subdivided into six groups according to metformin administration as mono-or dual therapies. RESULTS: The current results exhibited a significant elevation in systolic blood pressure, total and LDL-cholesterol levels and IFN-γ as well as a noticeable decrease in HDL-cholesterol and anti-atherogenic factor values compared to the healthy patients. Leukocytes and neutrophils count, main platelets volume (MPV) and platelet distribution width (PDW) values revealed noticeable elevations in most treated T2DM groups, while a marked depletion was recorded in platelets count compared to healthy subjects. Glycemic control, most treated diabetic patients with metformin mono- and dual therapies showed an ameliorative effect in HbA1c, IFN-γ, MPV, and PDW values compared to recent diabetic ones. CONCLUSION: Diabetes was correlated significantly with dyslipidemia and atherogenic risk in parallel with an increase in IFN-γ production and hematological inflammatory biomarkers; leukocytes, neutrophil/lymphocyte and platelet/lymphocyte ratios, MPV and PDW values. The amelioration in inflammatory biomarkers was associated with improvement in glycemic control.

BACKGROUND: The discovery of direct-acting antiviral agents (DAA) is an outstanding achievement of modern medicine in the current century. The current study aimed to explore the effectiveness and safety of two regimens sofosbuvir (SOF) in combination with either ribavirin (RBV) or simeprevir (SMV) in chronic hepatitis C (CHC) genotype (GT) 4 patients in Egypt. METHODS: A total of 201 patients, treatment-naïve and experienced, with CHC GT4 infection were allocated into two groups based on the type of the regimen used. All eligible patients were treated orally with SOF plus daily oral weight-based RBV (24 weeks; group 1), or SOF plus daily oral SMV (12 weeks; group 2). RESULTS: In the patients who received SOF/RBV therapy for 24 weeks, a sustained virological response (SVR12) was achieved by 89% (90/101) of all patients, 92% (49/53) of naïve patients and 85% (41/48) of experienced patients. In the SOF/SMV group, the SVR12 rate was 92% (92/100) for overall patients, 93% (70/75) of naïve patients and 88% (22/25) of experienced patients. Adverse events (AEs) were reported in 70% of patients in the SOF/RBV group and 42% patients in the SOF/SMV group. The most common AEs in both groups were fatigue, headache, nausea, and dyspnea. CONCLUSIONS: The present comparative study suggests that both SOF/RBV and SOF/SMV combination regimens are highly effective in CHC GT4 treatment. However, the two-DAA regimen (SOF/SMV) may offer well-tolerated treatment, with a shorter duration and better safety compared to SOF/RBV.
ABSTRACT
BACKGROUND AND AIM: Clinical studies evaluating the efficacy of daclatasvir (DCV) for treatment of chronic hepatitis C virus (HCV) genotype 4 (GT4) infection are scarce. This study aims to evaluate the efficacy and safety of DCV plus sofosbuvir (SOF) with or without ribavirin (RBV) for treatment of Egyptian patients infected with HCV GT4. METHODS: Between April 2016 and March of 2017, a large cohort of 946 patients with chronic HCV GT4 was enrolled for completing the treatment. Patients were classified into two groups: group 1 (easy to treat) was treated with a dual therapy of SOF/DCV daily for 12 weeks and group 2 (difficult to treat) was treated with a triple therapy of SOF/DCV/RBV daily for 12 weeks. Efficacy and safety of the treatments were estimated, and baseline characters associated with sustained virological response at 12 weeks post-treatment (SVR12) were investigated. RESULTS: Among the patient's cohort, SVR12 was achieved by 94% (891/946) in the overall patients, by 95% (718/758) in the easy-to-treat group, and by 92% (173/188) in the difficult-to-treat group. The most common adverse events recorded were fatigue, headache, nausea, asthenia, and gastrointestinal troubles. No patient discontinued treatment due to severe adverse events. CONCLUSION: The findings from the present study suggested that SOF/DCV (with or without RBV) regimen exhibited high effectiveness, was well tolerated in the treatment of chronic HCV GT 4, and revealed itself as a better option for patients with advanced liver disease, making the eradication of HCV a more realistic target to achieve.

INTRODUCTION: New regimens involving direct-acting antiviral agents (DAAs) have recently been approved for the treatment of hepatitis C virus (HCV) genotype 4 (GT4). The current study aims to assess the efficacy and safety of sofosbuvir (SOF) with pegylated interferon (PegINF)/ribavirin (RBV) for chronic HCV GT4 patients at the beginning of the interferon-free era. MATERIAL AND METHODS: Between March 2015 and November 2015, 99 patients (59 naïve and 40 experienced) infected with HCV GT4 were enrolled in the study. Eligible patients received daily oral 400 mg SOF, RBV (body weight: < 75 kg, 1000 mg; < 75 kg, 1200 mg), the dose modified according to patient tolerability, plus 180 µg PegINFα-2 once weekly for 12 weeks. RESULTS: Among the patient cohort, sustained virological response 12 weeks after the end of treatment (SVR12) was achieved by 88% (87/99) of all patients, by 93% (55/59) of naïve patients and by 80% (32/40) of experienced patients. Regarding treatment failure, the data recorded 12% (12/99) of patients (4 null responses and 8 relapsers). Otherwise, the most common adverse events observed during the study included headache, nausea, fatigue, dyspnea, influenza-like illness, anemia, and leukopenia. CONCLUSIONS: SOF combination-based therapies were considered promising choice regimens for chronic HCV infection. The present findings suggest that the combination of the SOF/PegINF/RBV regimen was effective for Egyptian patients with HCV GT4. The recorded adverse events and viral outcome revealed the high need for further efforts to minimize the side effects of the current regimen and/or replace PegINF with additional potent DAA(s) to increase SVR12 to achieve 100%.
ABSTRACT
Hepatitis C is a major global health burden and Egypt has the highest prevalence of hepatitis C virus (HCV) worldwide. The current study was designed to evaluate the beneficial therapeutic effects of ethanolic extracts of Nigella sativa, Zingiber officinale and their mixture in Egyptian HCV patients. Sixty volunteer patients with proven HCV and fifteen age matched healthy subjects were included in this study. Exclusion criteria included patients on interferon alpha (IFN-α) therapy, infection with hepatitis B virus, drug-induced liver diseases, advanced cirrhosis, hepatocellular carcinoma (HCC) or other malignancies, blood picture abnormalities and major severe illness. Liver function enzymes, albumin, total bilirubin, prothrombin time and concentration, international normalized ratio, alpha fetoprotein and viral load were all assessed at baseline and at the end of the study. Ethanolic extracts of Nigella sativa and Zingiber officinale were prepared and formulated into gelatinous capsules, each containing 500 mg of Nigella sativa and/or Zingiber officinale. Clinical response and incidence of adverse drug reactions were assessed initially, periodically, and at the end of the study. Both extracts as well as their mixture significantly ameliorated the altered viral load, alpha fetoprotein, liver function parameters; with more potent effect for the combined therapy. In conclusion, administration of Nigella sativa and/or Zingiber officinale ethanolic extracts to HCV patients exhibited potential therapeutic benefits via decreasing viral load and alleviating the altered liver function, with more potent effect offered by the mixture.
