Treatment of Hepatitis C Cirrhotic Patients With Directly Acting Antivirals: A Multicenter Study

BACKGROUND

With the introduction of sofosbuvir-based regimens, high cure rates and decreased duration has been achieved. Several studies showed variances in SVR rates between different genotypes, with lower rates of SVR among cirrhotic patients. The aim of our study was to assess the safety and effectiveness of sofosbuvir-based antiviral regimens for the treatment of HCVinfected Egyptian cirrhotic patients.

METHODS

This was a retrospective, observational, and comparative study. A total of nine hundred and forty-six cirrhotic patients with chronic HCV genotype 4 infection, who were eligible for direct acting drugs (DAAs) therapy, were enrolled. The primary outcome measures were the number of patients with successful eradication of the virus evidenced by SVR at 12 weeks after discontinuation of therapy (SVR12), and the secondary outcome measures were the incidence of adverse effects associated with the tested HCV therapy.

RESULTS

Among the 946 patients enrolled in the study, 527 patients (55.7%) were males and 419 patients (44.3%) were females with a mean age of 54.00±8.88 years. 20.2% were diabetics and 19.1% were hypertensive. Patients were classified according to Child-Pugh classifications; 818 patients (86.46%) were Child-Pugh class A cirrhosis, while 28 patients (13.53%) were Child-Pugh class B cirrhosis. The SVR12 rate was 96.93% (917 /946). Treatment response in the Child-Pugh class A cirrhosis was 794 (97%) after 12 weeks, while treatment response in the Child-Pugh class B cirrhosis was 123 (96%). Mild side effects were observed in 76 patients.

CONCLUSIONS

Sofosbuvir based regimens were effective and safe in the treatment of cirrhotic patients with chronic hepatitis C genotype 4.

Maternal and Neonatal Morbidity and Mortality Among Pregnant Women With and Without COVID-19 Infection: The INTERCOVID Multinational Cohort Study

Importance

Detailed information about the association of COVID-19 with outcomes in pregnant individuals compared with not-infected pregnant individuals is much needed.

Objective

To evaluate the risks associated with COVID-19 in pregnancy on maternal and neonatal outcomes compared with not-infected, concomitant pregnant individuals.

Design, Setting, and Participants

In this cohort study that took place from March to October 2020, involving 43 institutions in 18 countries, 2 unmatched, consecutive, not-infected women were concomitantly enrolled immediately after each infected woman was identified, at any stage of pregnancy or delivery, and at the same level of care to minimize bias. Women and neonates were followed up until hospital discharge.

Exposures

COVID-19 in pregnancy determined by laboratory confirmation of COVID-19 and/or radiological pulmonary findings or 2 or more predefined COVID-19 symptoms.

Main Outcomes and Measures

The primary outcome measures were indices of (maternal and severe neonatal/perinatal) morbidity and mortality; the individual components of these indices were secondary outcomes. Models for these outcomes were adjusted for country, month entering study, maternal age, and history of morbidity.

Results

A total of 706 pregnant women with COVID-19 diagnosis and 1424 pregnant women without COVID-19 diagnosis were enrolled, all with broadly similar demographic characteristics (mean [SD] age, 30.2 [6.1] years). Overweight early in pregnancy occurred in 323 women (48.6%) with COVID-19 diagnosis and 554 women (40.2%) without. Women with COVID-19 diagnosis were at higher risk for preeclampsia/eclampsia (relative risk [RR], 1.76; 95% CI, 1.27-2.43), severe infections (RR, 3.38; 95% CI, 1.63-7.01), intensive care unit admission (RR, 5.04; 95% CI, 3.13-8.10), maternal mortality (RR, 22.3; 95% CI, 2.88-172), preterm birth (RR, 1.59; 95% CI, 1.30-1.94), medically indicated preterm birth (RR, 1.97; 95% CI, 1.56-2.51), severe neonatal morbidity index (RR, 2.66; 95% CI, 1.69-4.18), and severe perinatal morbidity and mortality index (RR, 2.14; 95% CI, 1.66-2.75). Fever and shortness of breath for any duration was associated with increased risk of severe maternal complications (RR, 2.56; 95% CI, 1.92-3.40) and neonatal complications (RR, 4.97; 95% CI, 2.11-11.69). Asymptomatic women with COVID-19 diagnosis remained at higher risk only for maternal morbidity (RR, 1.24; 95% CI, 1.00-1.54) and preeclampsia (RR, 1.63; 95% CI, 1.01-2.63). Among women who tested positive (98.1% by real-time polymerase chain reaction), 54 (13%) of their neonates tested positive. Cesarean delivery (RR, 2.15; 95% CI, 1.18-3.91) but not breastfeeding (RR, 1.10; 95% CI, 0.66-1.85) was associated with increased risk for neonatal test positivity.

Conclusions and Relevance

In this multinational cohort study, COVID-19 in pregnancy was associated with consistent and substantial increases in severe maternal morbidity and mortality and neonatal complications when pregnant women with and without COVID-19 diagnosis were compared. The findings should alert pregnant individuals and clinicians to implement strictly all the recommended COVID-19 preventive measures.

Hepatitis C Virus Infection and Treatment as Independent Prognostic Factors in Diffuse Large B-Cell Lymphoma Egyptian Patients

BACKGROUND

Egypt is one of the highest hepatitis C virus (HCV) endemic areas. Chronic HCV infection has extra-hepatic manifestations, including non-Hodgkin lymphoma (NHL). Diffuse large B-cell lymphoma (DLBCL) is commonly associated with HCV infection. The prognostic value of HCV infection and HCV treatment in patients with DLBCL remains unclear until now.

OBJECTIVE

The aim of our study is to evaluate the impact of HCV infection and HCV treatment as independent prognostic factors on the event-free survival (EFS) and overall survival (OS) in Egyptian patients with HCV associated DLBCL.

METHODS

This study included 353 patients with DLBCL, collected retrospectively. While 34 patients with HCV who received HCV antiviral therapy were collected prospectively. Patient's characteristics were collected from the patient records at the time of diagnosis. The status of the patients about HCV infection and HCV treatment were also recorded. Disease progression, relapse, retreatment or deaths were also verified through medical records. EFS and OS were calculated.

RESULTS

EFS and OS significantly decrease in HCV infected and HCV non-treated patients when compared with HCV non-infected and HCV treated patients, respectively. HCV infection but not HCV treatment was independently associated with EFS and OS using univariate and multivariate analysis.

CONCLUSION

Hepatitis C virus infection is an independent prognostic factor for EFS and OS in diffuse large B-cell lymphoma. HCV treatment is associated with higher EFS and OS but can not be considered as an independent prognostic factor.

Efficacy of combined Sofosbuvir and Daclatasvir in the treatment of COVID-19 patients with pneumonia: a multicenter Egyptian study

BACKGROUND

Limited experimental and clinical evidence suggests a potential role for sofosbuvir/daclatasvir in treating COVID19. We aim to evaluate the efficacy of generic sofosbuvir/daclatasvir in treating COVID-19 patients with pneumonia.

RESEARCH DESIGN AND METHODS

This multicenter prospective study involved 174 patients with COVID-19. Patients were randomized into two groups. Group A (96 patients) received sofosbuvir (400 mg)/daclatasvir (60 mg) for 14 days in combination with conventional therapy. Group B (78 patients) received conventional therapy alone. Clinical, laboratory, and radiological data were collected at baseline, after 7, 14, and 28 days of therapy. Primary endpoint was rate of clinical/virological cure.

RESULTS

A lower mortality rate was observed in group (A) (14% vs 21%, P = 0.07). After 1 month of therapy, no differences were found in rates of ICU admission, oxygen therapy, or ventilation. Additionally, a statistically significant shorter duration of hospital stay (9% vs 12%, P < 0.01) and a faster achievement of PCR negativity at day 14 (84% versus 47%, P < 0.01) were noticed in group (A).

CONCLUSION

Adding sofosbuvir/daclatasvir to conventional therapy of COVID-19 is promising. Their use is associated with shorter hospital stay, faster PCR negativity and may be reduced mortality.

Norepinephrine is More Effective Than Midodrine/Octreotide in Patients With Hepatorenal Syndrome-Acute Kidney Injury: A Randomized Controlled Trial

Background: Terlipressin is the first-line pharmacological treatment for hepatorenal syndrome. When terlipressin is unavailable, midodrine/octreotide or norepinephrine, with albumin, represent the alternative treatments. The comparative efficacy of these alternative regimens remains unclear.

Objective: To compare the efficacy of midodrine/octreotide to that of norepinephrine for the treatment of patients with hepatorenal syndrome.

Methods: In the intensive care setting, sixty patients with hepatorenal syndrome were randomized to initially receive either 0.5 mg/h of norepinephrine (maximum 3 mg/h) or 5 mg of oral midodrine three times/day (maximum 12.5 mg three times/day) plus octreotide (100 μg/6 h) as subcutaneous injection (maximum 200 μg/6 h), together with albumin (20–40 g/day). Treatment was allowed for a maximum of 10 days. Survival was analyzed for up to 30 days. The primary efficacy outcome was the proportion of patients who achieved full response, defined as the return of serum creatinine to a value within 0.3 mg/dl of the baseline at the end of treatment.

Results: There was a significantly higher rate of full response in the norepinephrine group (15/26, 57.60%) than the midodrine/octreotide group (5/25, 20%) (p = 0.006). Eleven (42.30%) patients in the norepinephrine group and 6 (24%) in the midodrine/octreotide group survived (p = 0.166).

Conclusion: Norepinephrine plus albumin is significantly more effective than midodrine and octreotide plus albumin in improving renal function in patients with hepatorenal syndrome.

Covid-19: Urgent Call to Action

Novel Corona Virus 2019 (COVID-19) is a new virus spread rapidly all over the world. It has specific respiratory or gastrointestinal tract symptoms. Its reported complications include respiratory distress, systemic inflammatory response syndrome, and septic shock. Due to heavy cytokines released by the virus; corticosteroids (40-120 mg / day) were given to severe cases to reduce pneumonia. It's a difficult task to control the spread of SARS-CoV-2, and to invent proper vaccines and treatments. In this review, the existing understanding of fatal, pandemic human coronavirus SARS-Cov2 (COVID-19), with special reference to its diagnosis, origin, transmission, and different approaches to develop its therapeutics, will be discussed.

Knowledge, Applicability, and Barriers of Telemedicine in Egypt: A National Survey

Objectives

The study is aimed at evaluating knowledge, attitude, and barriers to telemedicine among the general population in Egypt.

Methods

A questionnaire-based cross-sectional design was carried out among the general Egyptian population. A convenience sampling method was used to approach the eligible participants from University Teaching Hospitals of eight governorates from May to July 2020.

Results

A total of 686 participants filled the questionnaire (49.4% were males, mean age 36.7 ± 11.2 years old). Half of the participants stated that they previously used a telemedicine tool, mainly to follow up laboratory results (67.3%). Video or phone calls (39.3%) and mobile applications (23.7%) were the most commonly recognized telemedicine tools by the participants. The included participants exhibited a high level of knowledge and attitude towards telemedicine. On the other hand, 21.9% stated that telemedicine services could jeopardize patient privacy. 32.8% reported that telemedicine service could lead to disclosing medical information to people who are not authorized to do so. Almost half of the participants agreed to strongly agreed that telemedicine service could increase medical errors. 60.80% of the participants said that they are more likely to prefer telemedicine than traditional ways. However, 13.70% stated that telemedicine is more likely to be challenging to use.

Conclusion

The Egyptian population has high knowledge about the applications of telemedicine. In addition, the vast majority of Egyptians appear to perceive the benefits of telemedicine positively and are willing to use it. However, some barriers that have been found must be taken into consideration to adopt telemedicine successfully, especially for people who are old, are low educated, and live in remote areas. Future studies should address the utility of telemedicine in improving the quality of healthcare and patient's health outcome and quality of life.

The Effect of Stem Cell Transplantation Therapy for Post Viral Chronic Liver Cell Failure on Associated Type II Diabetes Mellitus: A Pilot Study

BACKGROUND

It was observed that type II diabetes mellitus associated with chronic liver failure improved after stem cell transplantation. However, there were no adequate studies regarding this issue. The aim of this study was to evaluate the effect of stem cell transplantation on associated type II diabetes mellitus and on the liver function tests.

METHODS

This pilot study included 30 patients of post-hepatitis chronic liver failure who were classified into two groups: Group I included patients with chronic liver cell failure associated with type 2 diabetes. Group II included patients without type II diabetes. Autologous CD34+ and CD133+ stem cells were percutaneously infused into the portal vein. Responders (regarding the improvement of diabetes as well as improvement of liver condition) and non-responders were determined. Patients were followed up for one, three and six months after the intervention evaluating their three-hour glucose tolerance test, C- peptide (Fasting and postprandial), Child-Pugh score and performance score one month, three months, and six months after stem cell therapy.

RESULTS

Both synthetic and excretory functions of the liver were improved in 10 patients (66.66 %) of group I and in 12 patients (80 %) of group II. Significant improvement in the Oral Glucose Tolerance Test in the responders of both the groups was well defined from the 3rd month and this was comparable to changes in liver function tests and Child-Pugh score.

CONCLUSION

Successful stem cell therapy in chronic liver cell failure patients can improve but not cure the associating type 2 diabetes by improving insulin resistance.

Timing of surgery following SARS-CoV-2 infection: an international prospective cohort study

Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.

Hemodynamic Changes of Hepatic & Renal Vessels in Systemic Bacterial Infection with Fever in HCV Related Cirrhosis

OBJECTIVES

To study the hemodynamic changes of hepatic & renal vessels in systemic bacterial infection with fever in HCV related cirrhosis with possible complications.

METHODS

Three groups of patients with systemic bacterial infection with fever were included in the study; group І included 15 patients with decompensated cirrhosis, group ІІ included 15 patients with compensated cirrhosis and group ІІІ included 10 patients without liver affection. Laboratory parameters and Doppler US of hepatic and renal vessels were evaluated during and after subsidence of fever in all patients.

RESULTS

Forty patients were enrolled in this prospective study. There were 22 male and 18 female patients. We found that the direction of blood flow in the portal and splenic veins was hepatopetal and the veins were non pulsatile in all cases with no change during and after subsidence of infection. There was no significant difference in portal or splenic vein diameters during and after subsidence of infection in the three studied groups. However, the mean values of portal and splenic veins peak velocities were significantly lower during infection in cirrhotic groups. The mean value of hepatic artery resistive index during fever was significantly higher than after fever in cirrhotic groups. Renal resistive and pulsatility indices were significantly higher during fever in cirrhotic groups.

CONCLUSION

Systemic bacterial infection with fever can affect hepatic haemodynamics leading to aggravation of portal hypertension and increasing the risk of complications as variceal bleeding and hepatic encephalopathy and can also affect renal haemodynamics with increased risk of renal impairment.

Predictive and Prognostic Value of Ascitic Fluid Mannose Binding Lectin in Patients with Spontaneous Bacterial Peritonitis

BACKGROUND

Spontaneous bacterial peritonitis is a common bacterial infection of ascitic fluid, mainly in ascites due to liver cirrhosis. Mannose-binding lectin (MBL) can activate phagocytosis and the complement system. Spontaneous bacterial peritonitis was detected to be higher in MBL deficiency. This study aimed to assess ascitic fluid MBL in liver cirrhosis and spontaneous bacterial peritonitis.

METHODS

Ninety patients with cirrhotic ascites were included. Forty five of them had SBP. Child- Pugh score, Model for End Stage Liver Disease (MELD) and its update (uMELD) scores were used to assess the severity of liver cirrhosis. Ascitic fluid samples were obtained for differentiation of leucocytic count, estimation of albumin, protein, glucose, and serum-ascitic albumin gradient. Ascitic fluid levels of MBL were measured for all patients. SBP was documented if polymorphonuclear leucocytic count ≥250/mm in ascitic fluid.

RESULTS

Ascitic fluid MBL level was significantly lower in patients with SBP. MBL had a significant negative correlation with ascitic total leukocytic count (TLC), also with serum creatinine, bilirubin, PT, INR and MELD score among SBP patients. However, it had a significant positive correlation with ascitic protein and with platelets. According to multivariate analysis, fever, TLC, platelets, creatinine, MBL, glucose and polymorphs were independent predictors for SBP development.

CONCLUSION

Ascitic fluid MBL could be a good predictive and prognostic marker in patients with cirrhosis and spontaneous bacterial peritonitis.

Utility of Lung Ultrasound in Decision making to prioritize hospital admission for COVID-19 patients: A Developing Country Perspective

BACKGROUND & AIMS

In healthcare settings with limited resources, it is crucial to make a plan to prioritize hospital admission for patients affected by COVID-19. So, we tried to develop a novel approach for triaging COVID-19 patients and deciding the priority for hospital admission using Lung Ultrasound. In this study, we aimed to evaluate the efficacy of lung ultrasound in triaging suspected COVID-19 patients and assessment of the severity of COVID-19 pneumonia and its comparison with CT chest as the gold standard.

METHOD

This was a multicenter cross-sectional study enrolled on 243 COVID-19 confirmed patients presented to the emergency department in three major University hospitals in Egypt. Lung ultrasound was done by an experienced emergency physician or chest physician according to the local protocol of each hospital. Demographic, clinical, and laboratory data were collected from each patient. Each patient was subjected to CT chest and lung ultrasound.

RESULTS

A total of 243 confirmed COVID-19 patients were enrolled in this study, with a mean age of 46.7+10.4 years. Ground glass opacity (GGO), subpleural consolidation, trans-lobar consolidation, and crazy paving were reported in chest CT scans of 54.3%, 15.2%, 11.1%, and 8.6% of patients, respectively. B-line artifacts were found in 81.1% of COVID-19 patients, which was of confluent pattern in 18.9% of patients. The lung ultrasound findings of 197 patients (81.1%) were completely coincident with those of CT with a Kappa agreement value of 0.77, and this offered a diagnostic sensitivity of 74 %, a diagnostic specificity of 97.9 %, positive predictive value (PPV) of 90.2% and negative predictive value (NPV) of 93.6 % for lung ultrasound in triaging COVID-19 patients. Adding O2 saturation to the findings of lung imaging, the accuracy of evaluation of lung ultrasound to differentiate between severe and non-severe lung diseases showed that ultrasound had 100% sensitivity and specificity.

CONCLUSION

Lung Ultrasound with Oxygen saturation is a very efficient tool for decision-making to prioritize hospital admission for patients affected by COVID-19 in healthcare settings with limited resources.

Outcomes of Treatment and Predictors of Response to Sofosbuvir Plus Simeprevir in Hepatitis C Virus with Genotype-4 Infection

BACKGROUND & AIMS

Treatment plan of chronic HCV infection has dramatically improved after the introduction of different groups of Direct-Acting Antiviral (DAA) drugs. These drugs have been found to be safe and effective. Sofosbuvir (SOF) plus simeprevir (SMV) regimen has been shown to be tolerable and effective in treatment of patients with HCV genotype 1. The aim of the study was to evaluate the safety and the efficacy of combined sofosbuvir plus simeprevir treatment in genotype 4 chronic HCV patients.

METHODS

This open-label multicenter prospective study was carried out on 381 Egyptian patients with chronic hepatitis C virus- infection. Treatment experienced and treatment-naive patients were included. Subjects administrated a regimen of sofosbuvir (400 mg/ day) plus semiprevir (150 mg /day) for twelve weeks. Sustained Virological Response (SVR) was confirmed by undetectable HCV RNA by quantitative PCR 3 months after the end of the treatment.

RESULTS

97.6% (372 /381) of patients had SVR. None of the studied clinical and demographic characteristics were associated with the SVR status. However, patients who failed to achieve SVR showed low albumin level and high total leucocyte. The most common side effects of the studied regimen were headache, fatigue, itching, photosensitivity, and cough.

CONCLUSIONS

Twelve weeks' regimen of sofosbuvir plus simeprevir was considered to be safe and tolerable in the treatment of HCV genotype 4; also it was associated with high SVR (97.6%).

Mortality outcomes with hydroxychloroquine and chloroquine in COVID-19 from an international collaborative meta-analysis of randomized trials

Substantial COVID-19 research investment has been allocated to randomized clinical trials (RCTs) on hydroxychloroquine/chloroquine, which currently face recruitment challenges or early discontinuation. We aim to estimate the effects of hydroxychloroquine and chloroquine on survival in COVID-19 from all currently available RCT evidence, published and unpublished. We present a rapid meta-analysis of ongoing, completed, or discontinued RCTs on hydroxychloroquine or chloroquine treatment for any COVID-19 patients (protocol: https://osf.io/QESV4/ ). We systematically identified unpublished RCTs (ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, Cochrane COVID-registry up to June 11, 2020), and published RCTs (PubMed, medRxiv and bioRxiv up to October 16, 2020). All-cause mortality has been extracted (publications/preprints) or requested from investigators and combined in random-effects meta-analyses, calculating odds ratios (ORs) with 95% confidence intervals (CIs), separately for hydroxychloroquine and chloroquine. Prespecified subgroup analyses include patient setting, diagnostic confirmation, control type, and publication status. Sixty-three trials were potentially eligible. We included 14 unpublished trials (1308 patients) and 14 publications/preprints (9011 patients). Results for hydroxychloroquine are dominated by RECOVERY and WHO SOLIDARITY, two highly pragmatic trials, which employed relatively high doses and included 4716 and 1853 patients, respectively (67% of the total sample size). The combined OR on all-cause mortality for hydroxychloroquine is 1.11 (95% CI: 1.02, 1.20; I² = 0%; 26 trials; 10,012 patients) and for chloroquine 1.77 (95%CI: 0.15, 21.13, I² = 0%; 4 trials; 307 patients). We identified no subgroup effects. We found that treatment with hydroxychloroquine is associated with increased mortality in COVID-19 patients, and there is no benefit of chloroquine. Findings have unclear generalizability to outpatients, children, pregnant women, and people with comorbidities.

Nitazoxanide versus rifaximin in preventing the recurrence of hepatic encephalopathy: A randomized double-blind controlled trial

BACKGROUND/PURPOSE

Hepatic encephalopathy (HE) is a neuropsychiatric complication of liver cirrhosis. HE is associated with poor survival and detrimental effects on quality of life (QOL). The drawbacks of the long-term use of rifaximin in HE necessitates searching for alternative therapies. In this context, our study aimed at evaluating the safety and efficacy of nitazoxanide (NTZ) as compared to rifaximin (RFX) in preventing the recurrence of HE and assessing its impact on QOL.

PATIENTS AND METHODS

This prospective, randomized, double-blind controlled study included 60 patients who were randomly assigned to receive either rifaximin 550 mg twice daily (group 1; n = 30) or nitazoxanide 500 mg twice daily (group 2; n = 30) for 24 weeks. During the study period, the patients' neurological symptoms, mental status, and performance were monitored. The serum levels of HE triggers (ammonia, TNF-α, and octopamine) were assessed. The patients' health-related quality of life was also evaluated.

RESULTS

Six months after treatment, patients on NTZ therapy showed a statistically significant improvement in CHESS score and mental status. NTZ provided 136 days of remission vs 67 days of remission for patients on RFX (P₁  = .0001) and significant reduction in Child score (P₁  = .018). Additionally, NTZ showed a statistically significant decrease in serum ammonia, TNF-α, and octopamine levels as compared to rifaximin. Regarding QOL, NTZ group showed an improvement in total Chronic Liver Disease Questionnaire (CLDQ) score. Both groups experienced minor controllable side effects.

CONCLUSION

Nitazoxanide may represent a suitable and safe alternative therapy to rifaximin in preventing the recurrence of hepatic encephalopathy.

Management of liver disease patients in different clinical situations during COVID-19 pandemic

Chronic liver diseases are common worldwide, especially in developing countries. The rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)/(COVID-19) leads to the infection of many patients with underlying chronic liver diseases. As a relatively new disease, management of COVID-19, in the context of chronic liver disease, is mainly based on the experience of the treating physician and the available data. In this review, we summarize the available evidence about the management of liver disease patients, in the context of COVID-19 infection, which can increase the severity of viral hepatitis B. Also, its clearance in HBV patients is delayed. A sixfold increased severity of COVID-19 was reported in obese patients with metabolic associated fatty liver disease (MAFDL). In patients with autoimmune liver disease (AILD), it is not recommended to change their immunosuppressive therapy (as long as they are not infected with COVID-19), in order to avoid a flare of liver disease. However, immunosuppressant drugs should be modified, in the case of infection with COVID-19. To date, no data suggest an increased risk or severity in metabolic liver diseases, such as hemochromatosis, Wilson's disease, or alpha-1 antitrypsin deficiency. Patients with liver cirrhosis should be carefully managed with minimum exposure to healthcare facilities. Basic investigations for follow-up can be scheduled at wider intervals; if patients need admission, this should be in COVID-19-clean areas. Patients with hepatocellular carcinomas may have a poor prognosis according to preliminary reports from China. The course of COVID-19 in liver transplant recipients on immunosuppression seems to have a benign course, based on few reports in children and adults. The hepatotoxicity of COVID-19 drugs ranges from mild liver enzyme elevation to a flare of underlying liver diseases. Therefore, the decision should be customized. Telemedicine can minimize the exposure of healthcare workers and patients to infection with COVID-19 and decrease the consumption of personal protective equipment.

The Role of Serum Procalcitonin Level as an Early Marker of Ascitic Fluid Infection in Post Hepatitic Cirrhotic Patients

AIMS & BACKGROUND

The early diagnosis of spontaneous bacterial peritonitis (SBP) has been considered important in the overall patient's survival. Ascitic fluid culture examination performance, in the emergency setting, is time-consuming and not always available, so there is a need for easy to apply, rapid and reliable markers for diagnosis of patients with ascites. The present prospective study aimed to determine the early diagnostic value of serum procalcitonin (PCT) levels in decompensated cirrhotic patients (DCPs) with SBP.

METHODS

47 HCV cirrhotic patients with ascites were enrolled for this prospective study. The severity of cirrhosis was classified based on the Child-Pugh criteria. All patients were subjected to paracentesis and ascitic fluid (AF) culture. Serum PCT levels were measured using enzyme-linked fluorescence analysis (ELFA).

RESULTS

The diagnostic value of serum PCT levels and WBC/PLT ratios for detecting infections were serum PCT levels (3.63 ± 3.47 ng/mL) in DCPs with infections which were significantly higher than in DCPs without infections (0.505 ± 0.230 ng/mL); p < 0.05. The cut-off value for serum PCT levels was 0.7 ng/mL for the diagnosis of infections in DCPs, for which the sensitivity and specificity were 93.1% and 73.2%, respectively. The AUC was 0.91 (95% CI: 0.83-0.99).

CONCLUSION

Serum procalcitonin seems to provide satisfactory diagnostic biomarkers in SBP.

Outcomes following SARS-CoV-2 infection in patients with chronic liver disease: An international registry study

BACKGROUND & AIMS

Chronic liver disease (CLD) and cirrhosis are associated with immune dysregulation, leading to concerns that affected patients may be at risk of adverse outcomes following SARS-CoV-2 infection. We aimed to determine the impact of COVID-19 on patients with pre-existing liver disease, which currently remains ill-defined.

METHODS

Between 25th March and 8th July 2020, data on 745 patients with CLD and SARS-CoV-2 (including 386 with and 359 without cirrhosis) were collected by 2 international registries and compared to data on non-CLD patients with SARS-CoV-2 from a UK hospital network.

RESULTS

Mortality was 32% in patients with cirrhosis compared to 8% in those without (p <0.001). Mortality in patients with cirrhosis increased according to Child-Pugh class (A [19%], B [35%], C [51%]) and the main cause of death was from respiratory failure (71%). After adjusting for baseline characteristics, factors associated with death in the total CLD cohort were age (odds ratio [OR] 1.02; 1.01-1.04), Child-Pugh A (OR 1.90; 1.03-3.52), B (OR 4.14; 2.4-7.65), or C (OR 9.32; 4.80-18.08) cirrhosis and alcohol-related liver disease (OR 1.79; 1.03-3.13). Compared to patients without CLD (n = 620), propensity-score-matched analysis revealed significant increases in mortality in those with Child-Pugh B (+20.0% [8.8%-31.3%]) and C (+38.1% [27.1%-49.2%]) cirrhosis. Acute hepatic decompensation occurred in 46% of patients with cirrhosis, of whom 21% had no respiratory symptoms. Half of those with hepatic decompensation had acute-on-chronic liver failure.

CONCLUSIONS

In the largest such cohort to date, we demonstrate that baseline liver disease stage and alcohol-related liver disease are independent risk factors for death from COVID-19. These data have important implications for the risk stratification of patients with CLD across the globe during the COVID-19 pandemic.

LAY SUMMARY

This international registry study demonstrates that patients with cirrhosis are at increased risk of death from COVID-19. Mortality from COVID-19 was particularly high among patients with more advanced cirrhosis and those with alcohol-related liver disease.

Ramadan fasting and liver diseases: A review with practice advices and recommendations

Ramadan fasting is obligatory for Muslim healthy adults. However, there are many exemptions from fasting; including patients, whose diseases will be aggravated by fasting. Muslim patients with different liver diseases are frequently seen in the clinics discussing their intent to fast this month with their treating physicians. To answer our patients' inquiries about the expected benefits and/or risks of fasting and delivering them the best care, we carried out this review and we draw advices and recommendations based on the available evidence. A web-based search, combining multiple keywords representing different liver diseases with Ramadan fasting had been carried out. To answer the research question: Do adult Muslim patients with different liver diseases who fast the month of Ramadan have had a deleterious effect on their health in comparison to those who did not fast? Relevant publications were retrieved. No randomized controlled trials were focusing on Ramadan fasting and liver diseases in the filtered databases, eg Cochrane library. Consequently, non-filtered databases, eg PubMed, Google Scholar and Egyptian Knowledge Bank searched and full-text high-quality research articles were carefully analysed to draw recommendations. Other relevant publications with low quality of evidence like case studies and short communications were also reviewed to address practice advices. Although Ramadan fasting was found beneficial for patients with NAFLD, it was found deleterious to patients with Child B and C cirrhosis and patients with peptic ulcer. Patients with chronic hepatitis, Child A cirrhosis and those with non-complicated liver transplant can fast with prefasting assessment and strict follow up.

Effect of Direct-Acting Antiviral Drugs on Erectile Functions among Hepatitis C Patients: A Prospective Interventional Study

BACKGROUND & OBJECTIVE

Erectile dysfunction (ED) is one of the extrahepatic manifestations of hepatitis C virus infection that greatly affects patients' quality of life. Unfortunately, some of the drugs used for HCV treatment may have a negative impact on the patient's erectile function such as the pegylated interferon. Currently, with the introduction of directacting antiviral drugs, there are scarce data in the literature about its potential impact on erectile function. In these settings, we aimed to assess the impact of sofosbuvir-based therapy on male erectile function.

METHODS

This prospective interventional study was carried out in Benha University hospitals between January 2019 and May 2020. The study included all consecutive HCV patients with simultaneous ED coming to the hepatology outpatient clinic. Patients were divided into a study group who received sofosbuvir-based therapy (group A) or a control group who received silymarin therapy (group B). The International Index of Erectile Function-5 (IIEF-5) was used for assessment of erectile function at different time points (pretreatment, 6 months, and 12 months after treatment). Different variables in both groups have been statistically analyzed.

RESULTS

Overall, 75 patients who received sofosbuvir-based therapy and a control group (n = 35) matched for age and pretreatment variables (Child-Turcotte-Pugh score and Fibrosis- 4 score). There was no significant difference between both groups in the pretreatment data. On the other hand, the posttreatment IIEF-5 was significantly higher in the sofosbuvir arm compared to the silymarin arm both at six months (p<0.001) and at 12 months (p<0.001). Furthermore, the age and the stage of liver fibrosis were negatively correlated with IIEF-5 at all-time points.

CONCLUSION

The age and the stage of liver fibrosis are significantly correlated with the degree of ED. Furthermore, sofosbuvir-based therapy may be associated with significant improvement in the patients' erectile function.

Sofosbuvir/Ledipasvir for Treatment of Chronic Hepatitis C Infection in Adult Patients with β- Thalassemia Major: A Real-Life Study

Background&Aims:Patients with thalassemia have lifelong need for blood transfusion, makes them more risky to hepatitis C virus (HCV). Iron overload and chronic HCV are considered risk factors for patients with thalassemia to develop liver insults. The aim of the present study is to investigate the safety and efficacy of sofosbuvir/ledipasvir in treatment of chronic HCV infection in Egyptian adult patients with β- thalassemia major.

METHODS

Aretrospective study included 53 patients with β-thalassemia major with chronic HCV treated with sofosbuvir (400 mg) and ledipasvir (90 mg) as a single pill fixed dose combination once daily for 12 weeks. The effectiveness of treatment was assessed by sustained virologic response (SVR) at 12 weeks after the end of treatment.

RESULTS

SVR was achieved in 96.23% of patients. 47.17% of patients had minor side effects. There was a significant reduction in ALT, AST, and serum ferritin 12 weeks post-therapy. There was insignificant change in hemoglobin level, or blood transfusion requirement 12 weeks post-therapy. There was no change in iron chelators doses throughout the study period.

CONCLUSION

Sofosbuvir/ledipasvir regimen seems to be safe and highly effective in treatment of chronic HCV in patients with β-thalassemia major.

The Effect of HCV Eradication after Direct Acting Antiviral Agents on Hepatic Steatosis: A Prospective Observational Study

BACKGROUND AND AIMS

Eradication of hepatitis C virus (HCV) by direct-acting-antiviral-agents (DAAs) was followed by fibrosis regression, but little is available about hepatic steatosis changes after DAAs. The aim of this work was to assess the prevalence of hepatic steatosis among HCV Egyptian patients and the long term changes occur after viral eradication.

METHODS

This prospective cohort study included 150 HCV patients with significant fibrosis. They were examined by Transient elastography to evaluate liver stiffness measurement (LSM) and hepatic steatosis before treatment, at SVR12 and 1 year after end of therapy.

RESULTS

LSM showed significant positive correlation to pretreatment hepatic steatosis. LSM significantly decreased and hepatic steatosis significantly increased both at SVR12 and one year after DAAs. Patients with steatosis showed significantly higher median LSM and controlled attenuation parameter (CAP) values at: baseline, SVR12, and one year after therapy. Also, the pretreatment steatosis and body mass index (BMI) had significant negative correlation with fibrosis regression one year after therapy in all studied groups.

CONCLUSION

Hepatic steatosis is common in HCV Egyptian patients and increases after HCV eradication with DAAs. BMI and CAP values are negatively correlated to hepatic fibrosis regression and positively correlated to steatosis progression one year after DAAs. So, HCV patients with hepatic steatosis may need close follow up for atherosclerotic and HCC risk after DAAs especially if they are overweight.

Efficacy of favipiravir in COVID-19 treatment: a multi-center randomized study

No specific antiviral drugs have been approved for the treatment of COVID-19. This study aimed to evaluate the efficacy of favipiravir in treatment of COVID-19. This was a multicenter randomized controlled study including 96 patients with COVID- 19 who were randomly assigned into a chloroquine (CQ) group and a favipiravir group. None of the patients in the favipiravir group needed mechanical ventilation (p = 0.129). One patient (2.3%) in the favipiravir group and two patients (4.2%) in the CQ group died (p = 1.00). Favipiravir is a promising drug for COVID-19 that decreases the hospital stay and the need for mechanical ventilation.

Amyloid A in Serum and Ascitic Fluid as a Novel Diagnostic Marker of Spontaneous Bacterial Peritonitis

Background: Diagnosis of Spontaneous Bacterial Peritonitis (SBP) depends mainly on ascetic fluid culture which may be negative in spite of the clinical suggestion of SBP and high ascetic fluid neutrophilic count.

Aims: This study aimed to evaluate the biological importance of amyloid A biomarker in both serum and ascetic fluid to diagnose SBP as early as possible and to compare it to other markers (C-reactive protein (CRP), and the neutrophil-to-lymphocyte ratio (NLR)).

Methods: This study included 37 patients with hepatic ascites; twenty-two of them had SBP, and 15 patients did not have SBP. Serum and ascetic fluid amyloid A, ascetic fluid neutrophil, C-reactive protein, and neutrophil-to-lymphocyte ratio were measured in all subjects before the start of antimicrobial chemotherapy to the infected ones.

Results: Both the serum and ascetic fluid amyloid and also, CRP were significantly higher in patients infected with ascetic fluid than others. The cut-off point of serum amyloid A for early detection of SBP was 9.25ug/ml with the high sensitivity and specificity. For ascetic amyloid A, the sensitivity and specificity were 90.09% and 60% at cut-off point 2.85ug/ml, respectively.

Conclusion: Amyloid A in serum and ascitic fluid can be considered as a good biomarker for early diagnosis of SBP.
