RESUMO

BACKGROUND: We aimed to assess serum 25-hydroxyvitamin D3 (25(OH)D3) concentrations in extrapulmonary tuberculosis (EPTB) patients and to evaluate the effect of vitamin D3 supplementation on their treatment course. METHODS: Serum 25(OH)D3concentrations were measured in 47 newly diagnosed EPTB patients and 42 controls. Vitamin D-deficient EPTB patients were randomly assigned to receive 50,000 IU of vitamin D3 (cholecalciferol) orally once a week for 6 weeks (total 300,000 IU), followed by maintenance doses of 1000 IU a day besides anti-TB drugs or the first line anti-TB treatment only. Follow up serum 25(OH)D3 concentrations were measured after 3 months of starting vitamin D3 supplementation. Both groups were evaluated for clinical, laboratory, and radiological outcomes after treatment. RESULTS: Serum 25(OH)D3 concentrations were significantly lower among TB cases (17.1 ± 5.5 nmol/L) compared to healthy controls (51.8 ± 27.3 nmol/L), and vitamin D deficiency was observed in all EPTB patients (n = 47). Patients in VD3 supplementation group had significantly higher weight gain and serum albumin level at 2 months and end of treatment, higher hemoglobin concentration at the end of treatment, significantly lower CRP and ESR at 2 months and at the end of treatment. In cases with TB pleurisy, a significant higher rate of full resolution of pleural fluid after 6 months of anti-TB treatment and shorter treatment duration were noted compared to the other group. CONCLUSIONS: Vitamin D deficiency is prevalent in EPTB patients, in whom, vitamin D supplementation is a useful adjunctive therapy to anti-TB drugs and improves treatment course.

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

In AGATE-II, treatment with ombitasvir coformulated with paritaprevir/ritonavir plus ribavirin (RBV) in Egyptians infected with hepatitis C virus genotype 4 resulted in high rates of sustained virologic response at post-treatment week 12. This subanalysis examined the effects of treatment in AGATE-II on liver biomarkers in patients with compensated cirrhosis. AGATE-II was a phase 3, open-label, partly randomized trial of ombitasvir/paritaprevir/ritonavir with weight-based RBV daily once in treatment-naive or treatment-experienced patients. Patients without cirrhosis received treatment for 12 weeks and patients with compensated cirrhosis were randomized 1:1 to the same regimen for either 12 or 24 weeks. Sixty patients with compensated cirrhosis were randomized to treatment for 12 weeks (n = 31) or 24 weeks (n = 29). In the 12-week arm, significant improvements were observed in biomarkers of liver injury (alanine aminotransferase: -53.7 U/L, P < 0.001; aspartate aminotransferase: -35.9 U/L, P < 0.001) and liver fibrosis (aspartate aminotransferase to platelet ratio index: -0.987, P < 0.001; fibrosis-4 index: -1.165, P < 0.001). Similar results were reported in the 24-week arm. Treatment with ombitasvir/paritaprevir/ritonavir plus RBV in hepatitis C virus genotype, 4-infected Egyptians with compensated cirrhosis resulted in improvements in certain biomarkers of liver synthetic function, injury, and fibrosis, independent of treatment duration.

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 & AIMS: Major changes have emerged during the last few years in the therapy of chronic HCV. Several direct acting antiviral agents have been developed showing potent activity with higher rates of sustained virological response, even in difficult-to-treat patients. This study explores real life experience concerning efficacy, safety and possible predictors of response for the first cohort of Egyptian patients with chronic HCV genotype IV treated with Sofosbuvir/Simprevir combination therapy. METHODS: This real life study recruited the first (6211) chronic HCV genotype IV Egyptian patients, who received antiviral therapy in viral hepatitis specialized treatment centres affiliated to the National committee for control of viral hepatitis. All enrolled patients received 12 weeks course of daily combination of sofosbuvir (400 mg) and simeprevir (150 mg). Patients were closely monitored for treatment safety and efficacy. RESULTS: Overall sustained virological response 12 rate was 94.0% while the end of treatment response rate was 97.6%. sustained virological response 12 rates in easy and difficult-to-treat groups were 96% and 93% respectively. Univariate and multivariate logistic regression analysis revealed significant association of low albumin (<3.5), cirrhosis and Fib-4 score (>3.25) with treatment failure. Fatal adverse events occurred in 23/6211 cases (0.37%) due to liver cell failure adverse events or SAEs leading to treatment discontinuation occurred in 97 patients (1.6%). CONCLUSION: Sofosbuvir/Simeprevir combination is an effective and well tolerated regimen for patients with chronic HCV genotype IV.

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

Hepatitis delta virus (HDV) usually have an unfavorable clinical outcome in chronic hepatitis B virus (HBV) patients. In Egypt, data about epidemiology, the spectrum of disease, and impact of HDV on HBV infection are rare. To assess the prevalence, clinical and virological characteristics of HDV infection among Egyptian patients with chronic HBV. Adult patients with Hepatitis B surface antigen (HBsAg)-positive were evaluated for the presence of HDV using anti HDV-IgG and HDV RNA by RT-PCR. Routine laboratory investigations, genotypes and subtypes for both HBV and HDV, abdominal sonography, and transient elastography (TE) were done. Liver biopsy was performed only in whenever indicated. One hundred and twenty-one treatment-naïve chronic HBV patients were included. Wild HBV genotype-D2 was found in 98.2% and 81.9% were HBeAg negative. Prevalence of HDV was 8.3% by anti-HDV IgG and 9.9% by RT-PCR. Wild HDV genotype-IIb was reported in 83.3%. HDV infection was more common in males, 90.9% of delta patients were HBeAg negative. Compared to the mono-infected HBV, concomitant HBV/HDV infection was not associated with more derangment in ALT nor advanced stage of fibrosis. 66.7% of HDV patients had significantly lower HBV-DNA level compared to the non-delta patients (P < 0.001). HDV is not uncommon in Egypt. HBV genotype-D was associated with HDV genotype-IIb. Delta infection was associated with negative HBeAg status, reduction of HBV replication, but neither influenced the clinical course nor increased significant liver damage risk.

RESUMO

BACKGROUND & AIMS: Egypt has the highest prevalence of chronic hepatitis C virus (HCV) infection in the world, and more than 90% of patients are infected with genotype 4 virus. We evaluated the efficacy and safety of the HCV polymerase inhibitor sofosbuvir in combination with ribavirin in HCV genotype 4 patients in Egypt. METHODS: Treatment-naïve or treatment-experienced patients with genotype 4 HCV infection (n=103) were randomly assigned to receive either 12 or 24 weeks of sofosbuvir 400 mg and ribavirin 1000-1200 mg daily. Randomization was stratified by prior treatment experience and by presence or absence of cirrhosis. The primary endpoint was the percentage of patients with HCV RNA <25 IU/ml 12 weeks after therapy (SVR12). RESULTS: Among all patients, 52% had received prior HCV treatment and 17% had cirrhosis at baseline. SVR12 rates were 90% (46/51) with 24 weeks and 77% (40/52) with 12 weeks of sofosbuvir and ribavirin therapy. Patients with cirrhosis at baseline had lower rates of SVR12 (63% 12 weeks, 78% 24 weeks) than those without cirrhosis (80% 12 weeks, 93% 24 weeks). The most common adverse events were fatigue, headache, insomnia, and anemia. Two patients experienced serious adverse events (cerebral ischemia, dyspnea). No adverse events resulted in treatment discontinuation. CONCLUSION: Sofosbuvir plus ribavirin for 12 or 24 weeks is effective in treating both treatment-naïve and treatment-experienced Egyptian patients with genotype 4 HCV.

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

BACKGROUND AND STUDY AIMS: Recent reports have emphasized the increased risk of hepatocellular carcinoma (HCC) post direct-acting antiviral (DAAs) therapy in chronic hepatitis C virus (HCV) patients. Unfortunately, reliable diagnostic markers for HCC are still lacking. In this context, serum microRNAs have become promising diagnostic targets. Thus, the current study aims to elaborate the diagnostic utility of microRNA 122-5p, microRNA 21-5p, and microRNA 222-3p in the serum of Egyptian patients presenting with HCV infection and HCC post DAA therapy. PATIENTS AND METHODS: Qiagen specific microRNA assays were utilized to assess the expression levels of the chosen microRNAs in the serum samples collected from 3 groups: (1) 50 patients with HCV-related HCC, (2) 50 patients with HCC post DAA therapy, and 20 healthy control. RESULTS: The mean serum values of microRNA 21-5p and microRNA 122-5p were significantly lower in the HCC post DAA therapy group than in both the group with HCC without prior exposure to DAAs (P < 0.001) and control group (P 0.05 and 0.02, respectively). A significant upregulation was observed for both microRNA 21-5p and microRNA 122-5p in the HCV-related HCC group compared with the control group (P < 0.001 and = 0.011, respectively). On the other hand, the mean serum value of microRNA 222-3p was significantly raised in the HCC post DAA therapy group than in the control group (P = 0.007), whereas no statistically significant difference was observed between both groups with HCC and between the group with HCV-related HCC without prior exposure to DAAs and control group. CONCLUSION: This is the first study to introduce microRNA 21-5p, microRNA 122-5p and microRNA 222-3p as noninvasive biomarker candidates for HCC post DAA therapy. Their altered expression among treatment-naive HCC and HCC post DAA therapy might assume a different microRNA profiling in both HCC groups.

RESUMO

BACKGROUND: HIV-related stigma and discrimination (SAD) have imposed serious adverse health consequences on people living with HIV (PLHIV), including limited access to medical care and delayed diagnosis, which in turn limits the prevention and control of the disease. This study was conducted to explore the stigmatizing attitudes and behaviors of healthcare workers (HCWs) towards HIV patients and PLHIV. METHODS: A cross-sectional study targeted HCWs who attended the United Conference of Hepatogastroenterology and Infectious Diseases that was held on 25-28 September 2019 in Cairo governorate. A self-administrated questionnaire was completed by 359 HCWs. RESULTS: The majority of HCWs reported some discriminatory practices when rendering care to HIV patients, with nurses showing the highest significant number of discriminatory practices. A considerable proportion of HCWs reported witnessing HIV-related SAD at their health facilities. CONCLUSIONS: HIV-related SAD was prevalent among HCWs. Hence, HIV-related training relevant to the needs of different groups of HCWs is recommended. Provision of infection control supplies to protect against occupational exposure is also needed. The setting and enforcement of anti-stigma policies and guidelines in various healthcare settings are crucial.

RESUMO

BACKGROUND: Neutralizing antibodies (NAbs) against SARS-CoV-2 infection have a pivotal role in protective immune response; however, their measurement requires specialized facilities. We evaluated the degree of correlation between NAbs and anti-SARS-CoV-2 IgG/total Ig antibodies detected by chemiluminescent immunoassay in asymptomatic and previously symptomatic SARS-CoV-2 patients. METHODS: A total of 1241 participants (previously symptomatic patients and asymptomatic individuals), who were screened for SARS-CoV-2 infection by RT-PCR or serology, were enrolled in our study. Sera were analyzed for the presence of anti-spike-1(S1)-SARS-CoV-2 IgG/total Ig antibodies, using Ortho Clinical Diagnostics, USA. A signal/cut-off value (S/CO) ≥ 1 was considered reactive. NAbs were measured in 103 random samples from groups using microneutralization assay, with titer ≥ 1:10 being considered positive. RESULTS: Asymptomatic (n = 229) and 261 previously symptomatic individuals with positive serology and negative RT-PCR were finally included. Significant higher anti-S1-IgG titers were seen in asymptomatic individuals (P < 0.0001). Conversely, anti-S1-total Ig titers were significantly higher in previously symptomatic (P < 0.0001). NAbs were detected in both groups, however, higher titers were seen in previously symptomatic patients. There is a correlation between NAbs and both IgG/total anti-S1-SARS-CoV-2 antibodies (r = 0.47, P < 0.0001 and r = 0.49, P < 0.0001, respectively). IgG and total Ig could predict a neutralization titer of ≥ 1:160 at S/CO >4.44 and >65 with AUC 0.69 and 0.67, respectively. CONCLUSION: Asymptomatic SARS-CoV-2 infection can produce comparable antibodies response to previously symptomatic individuals, however higher neutralization activity was seen in the previously symptomatic. Anti-S1-SARS-CoV-2 IgG/total Ig antibodies showed a correlation with neutralization activity and can be used to estimate the presence of protective immunity.

RESUMO

OBJECTIVE: To assess the expression of IL-4, IL-17 and CD-163 as well as study of IL6-572 C/G gene polymorphism in chronic HCV and HCC on top of HCV. METHODS: Sixty HCC specimens and 60 adjacent hepatic tissue with HCV of different grades of necro-inflammation and different stages of fibrosis. In addition to 55 HCV, 60 HCC and 50 healthy venous blood samples for evaluation of IL6-572 C/G gene polymorphism. RESULTS: high expression of IL-4, IL-17 and CD163 in higher grades of activity, late stages of fibrosis and higher degrees of steatosis of HCV. IL-4 and CD163 showed higher expression in advanced grades of HCC, while IL-17 more expressed in lower grades. No significant difference in IL6-572 C/G gene polymorphism among studied groups regarding G/C, G/G, C/C frequencies or G and C allele's frequencies. CONCLUSION: IL-4, IL-17 and CD163 were associated with HCV severity. Their expression in HCC suggests their important role in HCC development. Blocking of these proteins may be a good target to control inflammation in HCV and can hinder progression to cirrhosis then to HCC. On the other hand, IL6-572 promoter gene polymorphism is neither associated with HCV infection nor with HCC development and its progression.

RESUMO

BACKGROUND AND AIM: Several studies performed in Western countries and Asia have shown that acute-on-chronic liver failure (ACLF) is an acute decompensation of cirrhosis characterized by organ system failures and high short-term mortality. However, the characteristics of Egyptian patients with ACLF have not yet been described. The aim of this study was to assess Egyptian patients with cirrhosis hospitalized for an acute decompensation using criteria and scores developed by the EASL-CLIF Consortium. PATIENTS AND METHODS: One hundred and twenty patients with acutely decompensated cirrhosis nonelectively admitted to two tertiary hospitals were prospectively included. Ninety-three percent of patients had hepatitis C virus-related liver disease. RESULTS: Of the 120 patients, 40 had ACLF; of these 45% had ACLF-1, 33% ACLF-2, and the remaining 22% had ACLF-3. None of the patients with ACLF had received direct-antiviral agents (DAAs) while 30% of patients without ACLF were treated with these agents. The prevalence of prior episodes of decompensation was significantly higher in patients with ACLF (60% vs. 28%). The prevalence of precipitating events such as bacterial infection alone or combined with gastrointestinal hemorrhage was higher in patients with ACLF than in those without. Systemic inflammation, assessed with white blood-cell count and plasma C reactive levels, was more intense in ACLF. CONCLUSION: Among Egyptian patients with acutely decompensated cirrhosis nonelectively admitted to the hospital, those with ACLF were distinct from those without ACLF, not only by the presence of organ failures, but also the absence DAA therapy, more frequent prior episodes of decompensation, more frequent bacterial infections as a precipitant, and more intense systemic inflammation.

RESUMO

BACKGROUND: Hiccups are involuntary diaphragmatic muscle contractions with early glottis closure terminating inspiration. They are classified into two types: acute (<48 hours) and persistent (>48 hours). COVID-19 is the defining health crisis of our generation. Although there are common symptoms of the disease (e.g. fever, cough), several atypical presentations have appeared as the pandemic has evolved. Here, we present a patient with COVID-19 presenting with fever, sore throat, and persistent hiccups. METHODS AND RESULTS: A 48-year-old man presented to the hospital with a seven-day history of persistent hiccups, fever, and sore throat. Physical examination was unremarkable and abdominal ultrasound showed gaseous abdominal distension. Laboratory values were remarkable for elevated C-reactive protein, ferritin, and lactate dehydrogenase levels. Computed tomography of the chest showed bilateral subpleural areas of ground-glass attenuation and crazy-paving pattern. A COVID-19 test was positive, and hydroxychloroquine, oseltamivir, baclofen, and symptomatic treatment were initiated. The hiccups improved, and the patient was discharged home after ten days. CONCLUSION: Physicians should maintain a high level of suspicion and be aware of atypical presentations of COVID-19.

RESUMO

OBJECTIVE: Little is known about how the achievement of sustained virological response (SVR) after treatment with direct-antiviral agents (DAAs) affects fibrosis and clinical outcomes in the long term. Our study aimed to evaluate the impact of achieving SVR on long-term changes in fibrosis and clinical outcomes in CHC patients treated with different DAAs-based regimens. METHODS: a prospective, 3-year follow-up study of 113 CHC patients who had achieved SVR after treatment with different DAAs-based regimens between January and June 2015 was conducted. The clinical outcomes of SVR on the biochemical profile, changes in fibrosis, ALBI score and grade and occurrence of liver-related events were analyzed. RESULTS: Overall, liver function parameters and serum alpha-fetoprotein level showed improvement from baseline to SVR12 and remained steady thereafter. Moreover, the ALBI score showed nonsignificant change at baseline to SVR12 (P = 0.2) but it was significantly better at 3-years follow-up than at SVR12 (P = 0.001). Regarding liver stiffness (LS) by transient elastography, a significant decrease in TE values was observed between baseline to SVR12 (P ≤ 0.0001) as well as between SVR12 to 3-years follow-up (P = 0.0005). Stratified by fibrosis stage, patients with advanced fibrosis and cirrhosis showed a more pronounced and significant improvement of LS during follow-up after SVR compared to patients with less advanced fibrosis stage. During the follow-up period, 3 (5.2%) cirrhotic patients developed liver-related events, including 2 (3.4%) patients with de novo HCC and one (1.7%) patient experienced ascites for the first time. CONCLUSION: This 3-year follow-up study provides evidence for the durability of SVR, improvement of liver function parameters and ALBI score and grade in patients with an advanced stage of fibrosis, in particular, and reduction of the clinical events after successful treatment with DAAs.

RESUMO

BACKGROUND AND STUDY AIMS: Assessing the extent of fibrosis is an essential part of therapeutic decisions in patients with chronic hepatitis C (CHC). Liver biopsies are the "gold standard" for evaluating liver fibrosis but have many limitations. Thus, noninvasive predictors of fibrosis have been developed. This study aimed to determine the effectiveness of red cell distribution width (RDW) to platelet ratio as a simple noninvasive method for predicting the hepatic fibrosis stage in patients with CHC. PATIENTS AND METHODS: This cross-sectional study included 197 Egyptian patients with CHC. A routine pretreatment reference needle liver biopsy was performed. Fib-4, transient elastography (TE) by Fibroscan, AST to Platelet Ratio Index (APRI), and RDW to platelet ratio (RPR) were measured. Predictors of significant fibrosis (Metavir score ≥ F2) and advanced fibrosis (Metavir score ≥ F3) were identified. RESULTS: Fib-4, TE, APRI, and RPR values differed significantly when comparing different stages of fibrosis (p < 0.01). Fib-4, TE, APRI, and RPR were reliable diagnostic tools at cutoff values of 1.17, 7.75, 0.18, and 0.07, respectively, for predicting significant fibrosis and cutoff values of 1.99, 8, 1.77, and 0.08, respectively, for predicting advanced fibrosis. Using logistic regression analysis, TE was identified as an independent predictor associated with significant and advanced fibrosis. Fib-4 was significantly associated with advanced fibrosis only. CONCLUSION: The use of Fib-4, TE, APRI, and RPR measurements may decrease the need for liver biopsies for predicting significant and advanced fibrosis. RPR showed fair sensitivity, specificity, positive and negative predictive values, and overall accuracy for predicting significant fibrosis in patients with CHC.

RESUMO

BACKGROUND: Healthcare workers (HCWs) represent a high-risk category during the coronavirus disease 2019 (COVID-19) pandemic crisis, with frontline HCWs at emergency departments (EDs) may be at an even higher risk. Determining the spread of infection among HCWs may have implications for infection control policies in hospitals. This study aimed to detect severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection among asymptomatic HCWs of the ED of a large tertiary center in Cairo, Egypt. METHODS: The study was conducted from June 1st to June 14th, 2020. All the recommended national and international indications on infection control measures were followed. Two hundred and three HCWs were included in the study and tested by nasopharyngeal swab (NPS) and rapid serological test (RST). Descriptive statistical analyses were used to summarize the data. RESULTS: Of the 203 HCWs, 29 (14.3 %) tested positive by real-time reverse transcription polymerase chain reaction (RT-PCR). Thirty-seven (18.2 %) HCWs tested positive with RST: 20 with both IgM and IgG; 14 with IgM only, and 3 with IgG only. Age, gender, and/or occupation were not risk factors for SARS-CoV-2 infection. CONCLUSIONS: Point prevalence of COVID-19 in asymptomatic HCWs in ED of tertiary care facility is 14.3 % by RT-PCR. This illustrates the importance of screening all HCWs regardless of symptoms, and the need for strict measures in securing HCWs to reduce transmission from healthcare facilities to the community during the current pandemic.
