RESUMO

OBJECTIVES: Chronic hepatitis C virus (HCV) infection is a debilitating disease that is lately treated using direct-acting antivirals (DAAs). Changes in the oral microbiome were detected in other liver diseases; however, oral microbiome was never investigated in patients having chronic HCV infection, whether pre- or post-treatment. MATERIALS AND METHODS: This case-control preliminary study enrolled three equal groups: Group (I): untreated HCV patients; group (II): HCV patients who achieved viral clearance after DAA administration; and group (III): healthy controls. For each participant, a buccal swab was harvested and its 16S rRNA was sequenced. RESULTS: The oral microbiome of chronic HCV patients had a significantly distinct bacterial community compared to healthy controls, characterized by high diversity and abundance of certain pathogenic species. These changes resemble that of oral lichen planus patients. After treatment by DAAs, the oral microbiome shifted to a community with partial similarity to both the diseased and the healthy ones. CONCLUSIONS: Chronic HCV is associated with dysbiotic oral microbiome having abundant pathogenic bacteria. With HCV clearance by DAAs, the oral microbiome shifts to approach the healthy composition.

RESUMO

Achieving global elimination of hepatitis C virus requires a substantial scale-up of testing. Point-of-care HCV viral load assays are available as an alternative to laboratory-based assays to promote access in hard to reach or marginalized populations. The diagnostic performance and lower limit of detection are important attributes of these new assays for both diagnosis and test of cure. Therefore, our objective was to determine an acceptable LLoD for detectable HCV viraemia as a test for cure, 12 weeks post-treatment (SVR12). We assembled a global data set of patients with detectable viraemia at SVR12 from observational databases from 9 countries (Egypt, the United States, United Kingdom, Georgia, Ukraine, Myanmar, Cambodia, Pakistan, Mozambique) and two pharmaceutical-sponsored clinical trial registries. We examined the distribution of HCV viral load at SVR12 and presented the 90th, 95th, 97th and 99th percentiles. We used logistic regression to assess characteristics associated with low-level virological treatment failure (defined as <1000 IU/mL). There were 5973 cases of detectable viraemia at SVR12 from the combined data set. Median detectable HCV RNA at SVR12 was 287,986 IU/mL. The level of detection for the 95th percentile was 227 IU/mL (95% CI 170-276). Females and those with minimal fibrosis were more likely to experience low-level viraemia at SVR12 compared to men (adjusted odds ratio AOR = 1.60 95% confidence interval [CI] 1.30-1.97 and those with cirrhosis (AOR = 1.49 95% CI 1.15-1.93). In conclusion, an assay with a level of detection of 1000 IU/mL or greater may miss a proportion of those with low-level treatment failure.

RESUMO

Little is known about evolution of platelet count after treatment with direct-acting antiviral agents (DAAs). The study aimed to evaluate the changes in platelet count after treatment with DAAs among thrombocytopenic patients with HCV-related advanced fibrosis and cirrhosis. A total of 915 chronic HCV patients with advanced fibrosis and cirrhosis who were treated with different DAAs-based regimens were retrospectively enrolled in final analysis. Included patients were those with thrombocytopenia (TCP). Platelet count was recorded at baseline, end of treatment (EOT) and 24-weeks after EOT (SVR24). Changes in platelet count and its relation to SVR were analyzed. The overall SVR24 rate was 98.8%. The platelet count showed statistically significant improvement from baseline to EOT (107 (84-127) × 103/mm3 vs. 120 (87-153) × 103/mm3(P = <0.0001) but remained unchanged thereafter to SVR24. Among responders, the platelet count significantly increased at SVR24 compared to baseline (P = <0.0001) but in relapsers, there was improvement in platelet count that didn't reach statistical significance (P = 0.9). Logistic regression analysis showed that higher Child-Pugh score and more advanced fibrosis at baseline were significant predictors of decreasing of platelet count and development of severe TCP at SVR24. Among thrombocytopenic patients with HCV-related advanced fibrosis and cirrhosis, the platelet count improved after treatment with DAAs regardless to treatment response.

RESUMO

PURPOSE: The impact of SOF-based therapy on renal functions is quite controversial in clinical practice. Therefore, we aimed to evaluate the serial changes of renal indices during SOF-based therapy in CHC patients with normal kidney function or mild renal impairment. METHODS: We retrospectively reviewed all CHC patients who received different SOF-based regimens from January 2015 until December 2017, and presented with a baseline eGFR ≥ 30 ml/min/1.73m2. Patients who didn't achieve SVR, with missing creatinine or eGFR data, and patients with eGFR less than 30 ml/min/1.73m2 at baseline were excluded. eGFR was calculated for each time of evaluation using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. RESULTS: A total of 1004 patients were finally included. The mean serum creatinine and eGFR levels varied between 0.84 mg/dl and 106.53 ml/min/1.73m2 for baseline and 0.87 mg/dl and 104.24 ml/min/1.73m2 for SVR12, respectively. The maximum increase of creatinine was 3.69 mg/dl and the maximum decrease of eGFR level was 83.30 ml/min/1.73m2 during treatment. Moreover, 74.4% of treated patients stayed in the same eGFR category, 14.3% progressed to a higher eGFR category, and 11.3% had an improvement eGFR category at EOT and continued to SVR12. Age > 65 years, baseline eGFR, and ribavirin-containing regimens were independent risk factors of eGFR decline during and after SOF-based treatment. CONCLUSION: SOF-based therapies seem to be safe in CHC patients with baseline normal or slightly impaired renal function.

RESUMO

OBJECTIVE: We evaluated the efficacy and safety of ledipasvir/sofosbuvir alone and with ribavirin for 8 and 12 weeks in Egyptian patients with and without cirrhosis, who were infected with hepatitis C virus (HCV) genotype 4, including those who had failed previous treatment with sofosbuvir regimens. DESIGN: In this open-label, multicentre, phase III study, treatment-naive patients were randomised to receive 8 or 12 weeks of ledipasvir/sofosbuvir±ribavirin. Interferon treatment-experienced patients were randomised to receive 12 weeks of ledipasvir/sofosbuvir±ribavirin, while sofosbuvir-experienced or ledipasvir/sofosbuvir-experienced patients received 12 weeks of ledipasvir/sofosbuvir+ribavirin. Randomisation was stratified by cirrhosis status. The primary endpoint was sustained virological response 12 weeks post-treatment (SVR12). RESULTS: We enrolled 255 patients from four centres in Egypt. Among treatment-naive patients, SVR12 rates were 95% and 90% for those receiving 8 weeks of ledipasvir/sofosbuvir alone and with ribavirin, respectively, and 98% for those receiving 12 weeks of ledipasvir/sofosbuvir both alone and with ribavirin. Among interferon-experienced patients, SVR rates were 94% for those receiving 12 weeks of ledipasvir/sofosbuvir and 100% for those receiving 12 weeks of ledipasvir/sofosbuvir plus ribavirin. All patients previously treated with sofosbuvir regimens who received ledipasvir/sofosbuvir plus ribavirin achieved SVR12. The most common adverse events, headache and fatigue, were more common among patients receiving ribavirin. CONCLUSION: Among non-cirrhotic treatment-naive patients with HCV genotype 4, 8 weeks of ledipasvir/sofosbuvir±ribavirin was highly effective. Twelve weeks of ledipasvir/sofosbuvir±ribavirin was highly effective regardless of presence of cirrhosis or prior treatment experience, including previous treatment with sofosbuvir or ledipasvir/sofosbuvir. TRIAL REGISTRATION NUMBER: NCT02487030.

RESUMO

BACKGROUND AND AIMS: The introduction of direct-acting antivirals for hepatitis C virus (HCV) in Egypt led to massive treatment uptake, with Egypt's national HCV treatment program becoming the largest in the world. The aim of this paper is to present the Egyptian experience in planning and prioritizing mass treatment for patients with HCV, highlighting the difficulties and limitations of the program, as a guide for other countries of similarly limited resources. METHODS: Baseline data of 337,042 patients, treated between October 2014 to March 2016 in specialized viral hepatitis treatment centers, were grouped into three equal time intervals of six months each. Patients were treated with different combinations of direct-acting antivirals, with or without ribavirin and pegylated interferon. Baseline data, percentage of patients with known outcome, and sustained virological response at week 12 (SVR12) were analyzed for the three cohorts. The outcomes of 94,258 patients treated in the subsequent two months are also included. RESULTS: For cohort-1, treatment was prioritized for patients with advanced fibrosis (F3-F4 fibrosis, liver stiffness ≥9.5 kPa, or Fibrosis-4 ≥3.25). Starting cohort-2, all stages of fibrosis were included (F0-F4). The prioritization strategy in the initial phase caused delays in enrollment and massive backlogs. Cohort-1 patients were significantly older, and more had advanced fibrosis compared to subsequent cohorts. The percentage of patients with known SVR12 results were low initially, and increased with each cohort, as several methods to capture patient results were adopted. Sofosbuvir-ribavirin therapy for 24 weeks had the lowest SVR12 rate (82.7%); while other therapies were associated with SVR12 rates between 94% and 98%. CONCLUSION: Prioritization based on fibrosis stage was not effective and enrollment increased greatly only after including all stages of fibrosis. The availability of generic drugs reduced costs, and helped massively increase uptake of the program. Post-treatment follow-up was initially very low, and although this has increased, further improvement is still needed. LAY SUMMARY: We are presenting the largest national program for HCV treatment in the world. We clearly demonstrate that hepatitis C can be cured efficiently in large scale real-life programs. This is a clear statement that global HCV eradication is foreseeable, providing a model for other countries with limited resources and prevalent HCV. Moreover, the availability of generic products has influenced the success of this program.

RESUMO

Assessment of hepatic fibrosis in chronic hepatitis C virus patients by liver biopsy is not widely accepted despite its accuracy, being invasive, carrying complications, and adding cost. This paved the way to development and use of non-invasive markers of fibrosis in diagnosis of hepatic fibrosis. We aimed at evaluating the efficiency of Fib-4, Egy-score, Aspartate-to-platelet ratio index (APRI), and Göteborg University Cirrhosis Index (GUCI) in comparison to liver biopsy, in the assessment of hepatic fibrosis in chronic hepatitis C patients. This was a cross sectional study including 200 chronic HCV patients were divided into two groups according to stage of fibrosis (Metavir score) into non-significant fibrosis (1.27, APRI >0.48, Egy-score >0.73, and GUCI >0.57 significantly predict significant fibrosis (P < 0.01). Fib-4 carries the best performance and significant reliability with AUROC 0.783, sensitivity 74%, specificity 69%, PPV 0.55, and NPV 0.86. The addition of BMI to Fib-4 improved the significant fibrosis AUROC curve performance but did not reach statistical significant improvement. We concluded that age and BMI are good predictors of hepatic fibrosis. Fib-4 (>1.27) is the best method of prediction of significant fibrosis compared to Egy-score, APRI, and GUCI. Addition of BMI to Fib-4 did not improve diagnostic value of Fib-4.

RESUMO

Serum levels of alpha-fetoprotein (AFP) were reported to increase in patients with significant or advanced hepatic fibrosis. Combination of non-invasive tests decreases the use of liver biopsy in large proportion of chronic HCV patients. The aim of the study was to compare and combine AFP with commonly used non-invasive fibrosis tests in novel scores for prediction of different stages of hepatic fibrosis. Six hundred and fifty two treatment naïve chronic hepatitis C patients were enrolled. Demographic data, basic pre-treatment laboratory tests including complete blood count (CBC), liver biochemical profile and renal functions test, international normalized ratio (INR) in addition to AFP, liver stiffness measurement (LSM) by Fibroscan and liver biopsies were retrospectively analyzed. AST to Platelet Ratio Index (APRI) and FIB-4 scores were calculated. Different predictive models using multivariate logistic regression analysis were generated and presented in equations (scores) composed of a combination of AFP, LSM plus FIB-4/APRI scores. AFP was correlating significantly with LSM, FIB-4, and APRI scores. Areas under receiver operating characteristic curves (AUROCs) for predicting significant hepatic fibrosis, advanced hepatic fibrosis, and cirrhosis were 0.897, 0.931, and 0.955, respectively, for equations (scores) containing AFP, LSM, and FIB-4. AUROCs for predicting significant hepatic fibrosis, advanced hepatic fibrosis and cirrhosis were 0.897, 0.929, and 0.959, respectively, for equations (scores) containing AFP, LSM, and APRI. The study shows that combining AFP to serum biomarkers and LSM increases their diagnostic performance for prediction of different stages of liver fibrosis.

RESUMO

Chronic HCV infection has emerged as a complex multifaceted disease with manifestations extending beyond the liver. HCV plays a direct role in glucose metabolism leading to both insulin resistance and type 2 diabetes. To evaluate the changes in the glycemic state following Sofosbuvir-based treatment regimens in diabetic HCV patients. Four hundred chronic hepatitis C patients who underwent Sofosbuvir-based treatment regimens were retrospectively screened. Sixty-five diabetic HCV patients only enrolled in our analysis. Baseline demographic and laboratory data were recorded. Pretreatment Transient elastography was performed. At 24-week post EOT (SVR24), Fasting Plasma glucose, and Hemoglobin A1c were re-evaluated and compared with baseline. All enrolled diabetic patients were responders. They showed statistically significant decline in Fasting Plasma glucose and Hemoglobin A1c values at SVR24. Whatever the degree of hepatic fibrosis, the level of Fasting Plasma glucose and Hemoglobin A1c decreased at SVR24 in comparison to baseline level. Fifty-one patients showed improvement in their Hemoglobin A1c values at SVR24 and this improvement was more likely to occur among patients with low Body mass index. The reduction in Fasting Plasma glucose >20 mg/dL (>1.1 mmol/L) and Hemoglobin A1c ≥0.5% was not associated with age, gender or hepatic fibrosis stage. Sofosbuvir-based regimens are a highly efficient antiviral therapy for diabetic chronic HCV patients resulted in improvement in Fasting Plasma glucose and Hemoglobin A1c.

RESUMO

BACKGROUND AND AIM: Accurate evaluation of the degree of liver fibrosis in patients with chronic liver diseases is crucial, as liver fibrosis is important in order to make therapeutic decisions, determine prognosis of liver disease and to follow-up disease progression. Multiple non-invasive methods have been used successfully in the prediction of fibrosis; however, early changes in non-invasive biomarkers of hepatic fibrosis under effective antiviral therapy are widely unknown. The aim of this study is to evaluate changes of transient elastography values as well as FIB-4 and AST to platelet ratio index (APRI) in patients treated with Sofosbuvir-based treatment regimen. METHODS: This is a retrospective study including 337 chronic HCV Egyptian patients with genotype 4 mainly. They were treated with Sofosbuvir-based treatment regimen. Transient elastography values were recorded as well as FIB-4 and APRI were calculated at baseline and SVR12. RESULTS: There was a significant improvement of platelets counts, ALT and AST levels, which in turn cause significant improvement in FIB-4 and APRI scores at SVR12. Liver stiffness measurements were significantly lower in SVR12 (14.8 ± 10.7 vs 11.8 ± 8.8 kPa, P = 0.000). About 77% of responders and 81.1% of cirrhotic patients showed improvement in liver stiffness measurements at SVR12.Univariate and multivariate regression analysis showed that failure to achieve improvement in liver stiffness measurements were significantly associated with relapsers and low baseline liver stiffness measurement. CONCLUSION: Sofosbuvir-based treatment resulted in a clinically significant improvement in parameters of liver fibrosis.

RESUMO

BACKGROUND: The hepatitis C virus (HCV) is a leading cause of liver disease and the consequent complications of cirrhosis. However, there is no precise biomarker to predict the patients at high risk of developing progressive disease. We showed previously the implication of low molecular mass polypeptide-7 (LMP-7) single nucleotide varia- tions in the response to combined pegylated IFN and ribavirin therapy in patients infected with HCV genotype 4. In this study, we examined the possible relationship between LMP-7 genotypes and both the degree of liver fibrosis and the transition from end stage of fibrosis to hepatocellular carcinoma (HCC). METHODS: LMP-7 single nucleotide variation at codon 49 (substitution from A to C) was determined using restriction fragment length polymorphism analysis in leucocyte DNA from healthy subjects (n = 36) and HCV-chronically infected patients of genotype 4 either with different grades of liver fibrosis (n = 77) or with hepatocellular carci- noma (n = 25). Chronic HCV-infected patients having liver fibrosis were categorized into two groups based on the degree of fibrosis, early fibrosis (F0-F2, n = 37) and late fibrosis (F3-F4, n = 40). RESULTS: Our results demonstrated that patients with the LMP-7 CA/AA genotypes were more likely to have advanced fibrosis scores than those bearing the CC genotype, although LMP-7 polymorphism does not seem to contribute to the progression from the late stage of fibrosis to hepatocellular carcinoma. CONCLUSIONS: These results suggest that LMP-7 polymorphism is a candidate prognostic marker in mathematical models designed for predicting the progression of HCV-related liver disease. Nevertheless, the mechanism whereby LMP-7 leads to the progression of liver fibrosis remains to be determined.

RESUMO

AIM: Serum markers and developed scores are of rising importance in non-invasive diagnosis of hepatic fibrosis. Aspartate aminotransferase-to-platelet ratio index (APRI), FIB-4 and Forns' index are validated scores used for diagnosis of liver fibrosis. The Egy-Score is a newly developed score for detection of hepatic fibrosis with promising results. We aimed to assess the accuracy of the Egy-Score in the diagnosis of significant fibrosis, advanced fibrosis and cirrhosis compared to APRI, FIB-4 and Forns' in chronic hepatitis C virus (HCV) patients. METHODS: A retrospective study including 100 chronic hepatitis C naïve Egyptian patients was performed. Patients were classified according to stages of fibrosis into three groups: significant fibrosis (≥ F2), advanced fibrosis (≥ F3) and cirrhosis (F4). Egy-Score, APRI, FIB-4 and Forns' index were calculated. Regression analysis and receiver-operator curves were plotted to assess the sensitivity, specificity and predictive values for the significant scores with the best cut-off for diagnosis. RESULTS: An Egy-Score of 3.28 or more was superior to APRI, FIB-4 and Forns' index for detecting advanced fibrosis with a sensitivity of 91% and specificity of 78%. An Egy-Score of 3.67 or more was superior to APRI, FIB-4 and Forns' index for detecting cirrhosis with a sensitivity of 82% and specificity of 87%. Forns' index was superior to Egy-Score, FIB-4 and APRI for detecting significant fibrosis. CONCLUSION: The Egy-Score is a promising, accurate, easily calculated, cost-effective score in the prediction of hepatic fibrosis in chronic HCV patients with superiority over APRI, FIB-4 and Forns' index in advanced hepatic fibrosis and cirrhosis.

RESUMO

BACKGROUND: Sofosbuvir (SOF) is authorized for hepatitis C virus (HCV) patients. The nephrotoxicity of SOF on HCV mono-infected and HCV-human immunodeficiency virus (HIV) individuals receiving antiretroviral therapy (ART) remains controversial. METHODS: A prospective study including 159 HCV mono-infected and 124 HCV-HIV individuals (47 were ART naïve and 77 were tenofovir [TDF]-based ART) who presented with an estimated glomerular filtration rate (eGFR) ≥30 ml/min/1.73 m2 at baseline and were treated with SOF-daclatasvir for 12 weeks. The eGFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration equation over the study period. RESULTS: HCV patients had a progressive decline in median levels of eGFR compared with HCV-HIV patients who were ART naïve and those receiving TDF-based ART during and after discontinuing SOF-DAC treatment (96, 109 and 114 at baseline vs 94, 117 and 108 at the end of treatment [EOT]) vs 95, 114 and 115 ml/min/1.73 m2 at 12 weeks after treatment [SVR12], respectively). Moreover, the rate of eGFR stage worsening was more pronounced in HCV mono-infected compared with HCV-HIV individuals who were ART naïve and those receiving TDF-based ART (21.4% vs 8.5% and 14.3% at EOT; 21.4% vs 2.1% and 6.5% at SVR12, respectively). Multivariable regression analysis showed that baseline variables were not independent predictors of eGFR stage worsening either at EOT or SVR12. CONCLUSIONS: Because the changes in eGFR were minimal and not of clinical significance, and TDF was not associated with an increase in renal dysfunction, SOF-based direct-acting antivirals could be safely used in HCV mono-infected and HCV-HIV individuals, even in those on TDF-based ART.

RESUMO

Hepatitis C virus (HCV) infection is one of the most common causes of liver pathology. It is a major etiological factor of continuous liver injury by triggering an uncontrolled inflammatory response, causing liver fibrosis and cirrhosis. Liver fibrosis is a dynamic process that can be reversible upon timely cessation of the injurious agent, which in cases of HCV is represented by the sustained virological response (SVR) following antiviral therapies. Direct-acting antiviral therapy has recently revolutionized HCV therapy and minimized complications. Liver fibrosis can be assessed with variable invasive and non-invasive methods, with certain limitations. Despite the broad validation of the diagnostic and prognostic value of non-invasive modalities of assessment of liver fibrosis in patients with HCV, the proper interpretation of liver stiffness measurement in patients after SVR remains unclear. It is also still a debate whether this regression is caused by the resolution of liver injury following treatment of HCV, rather than true fibrosis regression. Regression of liver fibrosis can possess a positive impact on patient's quality of life reducing the incidence of complications. However, fibrosis regression does not abolish the risk of developing hepatocellular carcinoma, which mandates regular screening of patients with advanced fibrosis.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV)-hepatitis C virus (HCV) co-infection is increasing due to their similar routes of transmission. Co-infection poses a big challenge. Information on the prevalence of HCV infection in Egyptian HIV individuals is scarce. METHODS: A cross-sectional study was conducted on 1004 HIV individuals who were recruited from July 2018 to March 2019. Blood samples obtained from HIV individuals were subsequently screened for HCV antibodies using the Murex anti-HCV (version 4) enzyme-linked immunosorbent assay test. HCV RNA was performed only on anti-HCV antibody-positive samples. Logistic regression was used to identify factors associated with HCV seroprevalence using SPSS (IBM, Armonk, NY, USA). RESULTS: Among 1004 participants, 349 exhibited a positive result for anti-HCV antibodies (34.8% [95% confidence interval 31.81 to 37.8]). The most commonly self-reported risk factor of HIV infection by the co-infected participants was intravenous drug use (IDU) (303/349 [86.8%]). In multinomial analysis, risk factors identified as statistically associated with HCV seroprevalence include IDU, history of surgical operations and dental procedures and HIV viral load (p<0.001, 0.032, <0.001 and 0.006, respectively). Under combination antiretroviral therapy (cART), the proportion of HIV mono-infected individuals with an undetectable HIV viral load was significantly higher than those with co-infection (p<0.0007). We also found that HIV-HCV co-infected participants exhibited significantly higher CD4+ cell counts than those with HIV mono-infection (p=0.04). CONCLUSIONS: The prevalence of HIV-HCV co-infection is higher in Egypt compared with other countries in Africa. It is essential to screen all HIV-infected patients for HCV infection for early identification, counselling and initiation of anti-HCV treatment.

RESUMO

BACKGROUND: The researchers conducted the current study to explore the perspectives of people living with HIV (PLHIV) on HIV-related discrimination and the delivery of healthcare services in healthcare settings. METHODS: An exploratory study using a qualitative approach was conducted among 46 PLHIV who were seeking HIV counselling and treatment from two HIV centres in the Cairo governorate using a purposive sampling technique. RESULTS: A thematic content analysis was used to examine the responses. Participants had a combination of positive and negative experiences. Some participants reported staff acceptance and friendliness towards HIV-positive patients on antiretroviral treatment. Most interviewees observed that staff took extra precautions when treating or caring for them. The majority stated that counselling about the effects of the treatment was inadequate and that testing was either too far from their homes or at overcrowded centres with long waiting times. All the interviewees recommended ongoing communication and HIV counselling skills for healthcare providers who are in contact with HIV patients. CONCLUSION: Most of the study participants were not satisfied with HIV services in the participating centres, as well as experiencing stigma. More investment in enhancing the quality of HIV service delivery and reinforcement of health worker competencies, mainly in HIV counselling, may improve satisfaction, bearing in mind HIV-related stigma in the centres involved.

RESUMO

Background: Egypt used to have one of the highest hepatitis C virus (HCV) infection prevalence rates worldwide, with an estimated HCV prevalence of around 4.5% to 6.7%. Objectives: To determine the HCV infection incidence rate amid Egyptian patients living with HIV. Method: A total of 460 HIV-positive patients were recruited in a retrospective cohort study from Imbaba Fever Hospital, Cairo, between January 2016 and March 2019. The patients had a negative baseline and at least one other HCV antibody test. Hepatitis C virus antibody testing was done by antibody sandwich third-generation enzyme-linked immunosorbent assay. The hepatitis C virus infection incidence rate among HIV-infected patients was calculated using the person-time incidence rate. Results: Two hundred and eighteen patients were finally included: 146 (31.7%) patients were excluded for having a positive baseline HCV Ab result and 96 patients were excluded for not having a follow-up HCV Ab test. Eighteen patients had HCV seroconversion (8.3%), achieving an incidence rate of 4.06 cases per 100 person-years (95% confidence interval: 3.87-4.24). Injection drug use (IDU) was the commonest risk factor among seroconverters, with an HCV incidence rate of 7.08 cases per 100 person-years. Injection drug use history was reported in 83.3% of the seroconverters and in only 47.2% of non-seroconverters; P = 0.005. Conclusion: Egyptian HIV-infected patients show a high incidence rate of HCV infection especially among those who have a history of IDU. Accordingly, attention should be paid for prevention, screening and timely treatment of HCV in patients infected with HIV. What this study adds: The demonstration of a high HCV infection incidence rate among HIV-infected patients and shows the need for screening and prevention in this population.

RESUMO

BACKGROUND: This study investigates different barriers preventing a cohort of Egyptian HIV/HCV coinfected patients from accessing HCV treatment, despite being available and free of charge, aiming to improve the long-term outcomes of coinfected patients and decreasing their liver-related morbidity and mortality. METHODS: This study included HIV patients who were referred to Kasr Alainy Viral Hepatitis Center to receive HCV treatment and who had to continue pretreatment assessment in order to receive direct acting antiviral agents free of charge. Patients who did not attend within 90 d were questioned via a telephone interview. Questions addressed sociodemographic status, HIV status and the main barriers to accessing healthcare. RESULTS: Overall, 474 HIV/HCV coinfected patients were eligible for HCV treatment and 223 (47.1%) patients did not complete work-up for HCV treatment. Fear of community stigma concerning HIV/HCV was the most important barrier to compliance with treatment (73.3%), followed by lack of a supportive work environment and employment opportunities (51.5%), whereas 39.3% stopped follow-up due to the lack of integrated services in the healthcare facility. CONCLUSIONS: Managing HCV in HCV/HIV coinfected patients still represents a major challenge, not only for healthcare providers, but also at a community level, to improve community awareness and manage the major obstacle facing those patients regarding community stigma.

RESUMO

OBJECTIVE: This study aimed at exploring the potential role of a panel of serum micro-RNA (miRNA) markers in liver fibrosis and hepatocellular carcinoma (HCC) diagnosis in patients with chronic hepatitis C virus (HCV) infection. METHODS: The study included 157 chronic HCV patients and 62 HCC patients who presented to the Cairo University Center for Hepatic Fibrosis, Endemic Medicine Department, from 2015 to 2017. Relevant clinical and laboratory data were collected and sera were subjected to miRNA expression profiling. Eleven miRNA markers were studied and receiver operating characteristic curves were constructed to investigate the best cutoff values of the miRNAs that showed altered expression in HCC compared to HCV-associated advanced fibrosis. RESULTS: miRNA expression profiling revealed 5 miRNAs (miR-124, miR-141, miR-205, miR-208a, miR-499a) were significantly upregulated and 2 miRNAs were significantly downregulated (miR-103a, miR-15a) in HCC compared to advanced fibrosis patients. No significant difference was observed in miRNA expression between advanced fibrosis and early hepatic fibrosis apart from a significant downregulation of miR-155-5p in advanced fibrosis. CONCLUSION: Serum miRNAs could serve as potential diagnostic tools for the diagnosis of HCC.
