RESUMO

COVID-19 infections accelerate liver decompensation and serious liver-related co-morbidities. The aim is to evaluate the safety and impact of COVID vaccines on hepatic disease progression in patients with advanced liver disease and to identify parameters that predict the occurrence of complications. The study involved 70 patients with advanced liver disease who were vaccinated with different COVID vaccines from January 2021 to April 2022. They were evaluated clinically. The laboratory investigation included a complete blood count, liver and kidney function tests, calculation of CTP and MELD scores, plasma levels of ammonia, abdominal ultrasound, and upper GI endoscopy. Twenty patients had experienced complications 64 ± 12 days from the last dose of a vaccination. Twenty patients (28.6%) developed hepatic decompensation and hypothyroidism (n = 11, 15.7%), and five (7.14%) patients developed splanchnic thrombosis. There were no COVID-19 reinfections except for two patients who received Sinopharm and developed vaccine-associated enhanced disease (2.9%). Complications after COVID vaccinations were correlated with ALT (r = 0.279, p = 0.019), serum sodium (r = -0.30, p = 0.005), creatinine (r = 0.303, p = 0.011), liver volume (LV) (r = -0.640, p = 0.000), and MELD score (r = 0.439, p = 0.000). Multivariate logistic regression revealed that LV is the only independent predictor (p = 0.001). LV ≤ 682.3 has a sensitivity of 95.24% and a specificity of 85.71% in predicting complications with an AUC of 0.935, p < 0.001. In conclusion, the hepatic reserve and prognosis in liver cirrhosis should be evaluated prior to COVID vaccinations using the MELD score and liver volume as promising risk stratification criteria. In summary, the research proposes a novel triaging strategy that involves utilizing the MELD score and liver volume as risk stratification parameters of the hepatic reserve and prognosis of advanced liver cirrhosis prior to COVID immunization to determine who should not receive a COVID vaccination.

RESUMO

BACKGROUND: Ulcerative colitis is a heterogeneous disease in terms of disease course, location, and therapeutic response. The current study was done to assess the alteration of the gut microbiome in UC patients and its relationship to severity, response to therapy, and outcome. PATIENTS AND METHODS: The study included 96 participants who were divided into a case group (n = 48, recent onset, treatment naive ulcerative colitis patients who were subdivided into mild, moderate, and severe subgroups based on Truelove-Witts and endoscopic severity) and a healthy control group (n = 48). All were subjected to a thorough history, clinical examination, colonoscopy, routine laboratory tests, and quantitative real-time PCR to quantify Bacteroides, Lactobacilli, Faecalibacterium prausnitzii, Veillonella, and Hemophilus in fecal samples at baseline and 6 months after treatment. RESULTS: Bacterial 16S rRNA gene sequencing revealed a significant reduction in the phylum Firmicutes in UC patients, with a significant predominance of the phylum Bacteriodetes. F. prausnitzii and lactobacilli were inversely proportional to disease severity, whereas Bacteroides, Hemophilus, and Veillonella were directly proportional to it. Six months after therapy, a statistically significant increase in F. prausnitzii and lactobacilli was observed, with a decrease in the levels of other bacteria. Lower baseline F. praustinizii (< 8.5) increased the risk of relapse; however, lower ESR (< 10), lower post-treatment CRP (< 6), lower Bacteroides (< 10.6) indefinitely protect against relapse. CONCLUSION: The gut microbiome of recently diagnosed UC showed lower levels of Lactobacilli, Faecalibacterium, and higher levels of Bacteroides and Veillonella, and the change in their levels can be used to predict response to therapy.

RESUMO

To retrospectively assess the impact of regular yearly administration of recombinant influenza and single administration of pneumococcal conjugate vaccines on the occurrence of serious respiratory infection including COVID-19 in patients with type 2 diabetes mellitus. Hundred patients with type 2 diabetes mellitus were given Vaxigrip and Prevnar13® vaccines and were evaluated by comprehensive clinical review, airflow screening questionnaire, and routine laboratory investigations with follow-up during the COVID-19 pandemic and compared to a control group of diabetic patients with the same inclusion criteria (n = 100). After Vaxigrip and Prevnar13, there is a significant improvement in respiratory symptoms and a decrease in the airflow screening questionnaire (p = 0.0001) with a significant improvement in inflammatory parameters as neutrophil-lymphocyte ratio, ESR, CRP, and platelet count. Four patients had mild COVID-19 (4%), mainly gastrointestinal with no complications. Twenty-one out of 32 (65.6%) patients in the control group had severe COVID-19. The hazard ratios of significant respiratory tract infection and death due to COVID-19 were 2.29 and 10.24 in the non-vaccinated control (p = 0.001).The severity of COVID-19 in diabetes correlated with HBA1C (p = 0.007), combined Vaxigrip and Prevnar13 vaccination (p = 0.0001), serum creatinine (p = 0.001), neutrophil-lymphocyte ratio (p = 0.001), and thrombocytopenia (p = 0.003). The present study suggested that the combination of Prevnar13 and Vaxigrip may be related to decreased occurrence of serious respiratory infections including COVID-19. Further randomized control trials may be needed to establish a direct causation between the two and clarify these associations.

RESUMO

Coronavirus disease 2019 (COVID-19) is a multisystem disease affecting respiratory, cardiovascular, gastrointestinal, neurological, immunological and haematological systems. The most important indices that have been studied are platelet (PLT) indices in addition to the PLT count and red blood cell distribution width (RDW). This retrospective study included 95 patients with COVID-19 and was conducted at the Hospital Isolation, Scientific and Medical Research Centre and Clinical Pathology Department at Zagazig University Hospitals, Egypt over 6 months from March to August 2021. All patients on admission had a full blood count, which included white blood cell (WBC) count, haemoglobin, RDW, PLT count and its indices in addition to PLT-to-WBC ratio (PWR) and PLT-to-lymphocyte ratio (PLR), which were calculated for all the study patients. There were significant linear correlations for higher levels of the PLR, PWR and RDW and mortality rate (p = 0.03, p < 0.001 and p < 0.001 respectively). Moreover, on multivariable analysis the RDW, PLT count and PWR levels were independent prognostic predictors for mortality with a hazard ratio [HR] of 1.25 (95% confidence interval [CI] 1.09-1.44, p = 0.002), 1.00 (95% CI 0.99-1.00, p = 0.03) and 2.3 (95% CI 1.21-4.48, p = 0.01) respectively. The RDW and PLT indices are accessible predictors that can be valuable prognostic factors for survival assessment and risk stratification of COVID-19.

RESUMO

INTRODUCTION: In patients with compensated advanced chronic liver disease (cACLD), the invasive measurement of hepatic venous pressure gradient is the best predictor of hepatic decompensation. This study aimed at developing an alternative risk prediction model to provide a decompensation risk assessment in cACLD. METHODS: Patients with cACLD were retrospectively included from 9 international centers within the Portal Hypertension Alliance in China (CHESS) network. Baseline variables from a Japanese cohort of 197 patients with cACLD were examined and fitted a Cox hazard regression model to develop a specific score for predicting hepatic decompensation. The novel score was validated in an external cohort (n = 770) from 5 centers in China, Singapore, Korea, and Egypt, and was further assessed for the ability of predicting clinically significant portal hypertension in a hepatic venous pressure gradient cohort (n = 285). RESULTS: In the derivation cohort, independent predictors of hepatic decompensation were identified including Stiffness of liver, Albumin, Varices, and platElets and fitted to develop the novel score, termed "SAVE" score. This score performed significantly better (all P < 0.05) than other assessed methods with a time-dependent receiver operating characteristic curve of 0.89 (95% confidence interval [CI]: 0.83-0.94) and 0.83 (95% CI: 0.73-0.92) in the derivation and validation cohorts, respectively. The decompensation risk was best stratified by the cutoff values at -6 and -4.5. The 5-year cumulative incidences of decompensation were 0%, 24.9%, and 69.0% in the low-risk, middle-risk, and high-risk groups, respectively ( P < 0.001). The SAVE score also accurately predicted clinically significant portal hypertension (AUC, 0.85 95% CI: 0.80-0.90). DISCUSSION: The SAVE score can be readily incorporated into clinical practice to accurately predict the individual risk of hepatic decompensation in cACLD.

RESUMO

BACKGROUND: Liver-related death is preceded by clinical decompensation; therefore, the risk stratification of decompensation in compensated advanced chronic liver disease (cACLD) is extraordinary significant. METHODS: The international, multicenter study included three cohorts from January 2009 to August 2021. In training cohort, the unfavorable Baveno VI criteria patients were used to develop the novel CHESS criteria to stratify decompensation risk. The Algorithm based on Baveno VI criteria plus CHESS criteria (ABC model) was validated in validation cohort, and used to diagnose clinically significant portal hypertension (CSPH) in hepatic venous pressure gradient (HVPG)-performed cohort. RESULTS: A total of 1377 cACLD patients were enrolled. In training cohort, multivariate analysis revealed that liver stiffness measurement (LSM), platelet count (PLT), albumin, alanine aminotransferase (ALT) and varices were the independent risk factors for hepatic decompensation. The novel CHESS criteria was produced (0.036 × LSM [kPa]) + (- 0.013 × PLT [109/L]) + (- 0.068 × Albumin [g/L])) + (- 0.016 × ALT [U/L]) + (0.651 × Varices [present: 1, absent: 0]), and < - 4.4, - 4.4 to - 3.1 and > - 3.1 indicated the low risk, medium risk, and high risk of decompensation, with a 3 year-time-dependent area under the curve (tAUC) of 0.851 (0.800-0.901). In validation cohort, the 3 year-tAUC of ABC model was 0.843 (0.742-0.943). Notably, in HVPG cohort, the high risk group was used to rule in CSPH with a positive predictive value of 93.0%. CONCLUSIONS: The ABC model can stratify the risk of decompensation in cACLD. HVPG evaluation can be waived in both low risk and high risk cACLD patients as they can be managed by Baveno VI criteria and non-selective ß-blockers intervention, respectively, and the remaining medium risk patients need further HVPG evaluation.

RESUMO

BACKGROUND/AIMS: Peptic ulcer bleeding is the most common cause of upper gastrointestinal tract bleeding. Platelet-rich plasma (PRP) enhances tissue repair, and is therefore used in various medical treatments. A combination of mechanical or electrothermal hemostasis has been recommended for upper gastrointestinal tract bleeding treatment. This study evaluated the additive efficacy of PRP in bleeding peptic ulcer hemostasis and recovery. METHODS: Eighty patients with peptic ulcer bleeding were initially treated by hemoclipping, and were randomly chosen for either additional PRP (n=40) or additional epinephrine (n=40) injections. Both groups were compared with regard to achieving hemostasis and the frequency of complications. RESULTS: Hemostasis was immediately achieved in both groups. Two patients (5%) in the PRP group and 8 (20%) patients in the epinephrine group experienced rebleeding after 15.9±2.8 and 12.3±3.7 days, respectively. They were managed by PRP injection in addition to proton pump inhibitor infusion. Hemoglobin was substantially increased in the PRP-treated group with full recovery occurring in 60.5% compared to 31.3% of patients in the epinephrine group (p=0.001). There was no recurrent bleeding in the PRP group, but 4/32 (12.5%) patients in the epinephrine group exhibited rebleeding. CONCLUSION: PRP showed additional benefit in reducing peptic ulcer bleeding with no reported significant complications. Clinical trial (NCT03733171).

RESUMO

The global incidence of coronavirus disease 2019 (COVID-19) continues to increase despite health care efforts. The disease is caused by coronavirus 2 with high transmission and mortality rates. Little is known about the management of COVID-19 in advanced liver disease. The aim of work was to propose a plan for management of this drastic disease in case of this specific population with review of medications that could be suitable for advanced liver disease. All the guidelines and medications available for treatment of COVID-19 were reviewed with selection of the less toxic medications that could be used in advanced liver disease. Drugs suitable to manage COVID-19 in patients with liver disease might include remdesivir intravenously, nitazoxanide + sofosbuvir, ivermectin, tocilizumab, convalescent plasma, and low molecular weight heparin in certain situations. Advanced liver disease is associated with portal hypertension and splenomegaly with reduction of blood elements and immune dysfunction and impaired T cell function. Thus, when confronted by cytokine storm as an immune response to COVID-19, there may be an increase in the mortality rate of these patients. Through this review, a plan to treat COVID-19 in this special group of patients with advanced cirrhosis is proposed.

RESUMO

BACKGROUND: Hepatitis C virus (HCV) infection may affect lipid metabolism by enhancing the circulating levels of inflammatory cytokines, together with its impact on endothelial function. AIM: To evaluate the potential correlation of changes in lipid profile, carotid intima-media thickness (CIMT), and ankle-brachial index with the severity of fibrosis, grades of esophageal varices (EVs), and fibrosis indices. METHODS: The study included 240 subjects who were divided into 3 groups; group 1 (n = 90, HCV-related cirrhotic patients with EVs), group 2 (n = 90, HCV-related cirrhotic patients without EVs), and group 3 (n = 60, served as the healthy control group). All patients underwent routine laboratory tests, including a lipid profile assay. Low-density lipoproteins (LDL)/platelet count and platelet/splenic diameter ratios were calculated. Abdominal ultrasonography, CIMT by carotid Doppler, bedside ankle-brachial index (ABI), liver stiffness measurement, and upper gastrointestinal endoscopy were performed. RESULTS: Multivariate logistic regression revealed that very-low-density lipoprotein (VLDL) (ß = 0.988, odds ratio 2.5, P = 0.001), LDL/platelet count ratio (ß = 1.178, odds ratio 3.24, P = 0.001), CIMT (ß = 1.37, odds ratio 3.9, P = 0.001), and ABI (ß = 2.3, odds ratio 5.9, P = 0.001) were the key variables associated with significant fibrosis, EVs and endothelial dysfunction. CIMT and LDL/platelet count ratio were predictive of advanced fibrosis and EVs at cutoff values of 1.1 mm and 1 mm, respectively, with an area under the curve (AUC) of 0.966 and 0.960 (P = 0.001), while VLDL and ABI at a cutoff of 16.5 mg/dL and 0.94 were predictive of advanced fibrosis and EVs with an AUC of 0.891 and 0.823, respectively (P = 0.001). CONCLUSION: CIMT, ABI, VLDL, LDL/platelet count ratio are good non-invasive predictors of advanced fibrosis, presence of EVs, and endothelial dysfunction in liver cirrhosis.

RESUMO

BACKGROUND: Calprotectin is a heterodimer formed by S100A8 and S100A9 proteins which are enhanced during hepatic carcinogenesis and the increased expression of both proteins promotes malignant progression of hepatocellular carcinoma. The potential correlation between ascitic Calprotectin and HCC was not studied. METHODS: 100 patients were stratified into a case group which enrolled 50 patients with cirrhotic ascites and documented HCC and a control group consisted of 50 patients with cirrhotic ascites without HCC. They were evaluated by liver function tests, abdominal ultrasound and routine ascitic fluid examination including ascetic Calprotectin and results were validated in another group (n = 100). RESULTS: Calprotectin level was significantly higher in the HCC group with insignificant difference regarding total cell count, PNLs, ascitic albumin, LDH, CEA and SAAG. It correlated with serum creatinine (r = 0.245, p = 0.014) and number of focal hepatic lesions (r = 0.309, p = 0.002). In the validation group, 28 patients had elevated ascitic Calprotectin of which 21 patients had developed HCC (75%) after a mean period of 3.8 ± 1.54 months. A cut of value 126 ng/ml was accurate to predict HCC in liver cirrhosis with ascites with a sensitivity of 93.3% specificity 94%, AUC 0.950, Youden's J value = 0.873, p = 0.0001. CONCLUSION: Ascitic Calprotectin may offer an easy, affordable marker that can predict the early occurrence of HCC.

RESUMO

Portal hypertensive polyposis is a rare finding represented in about 2.5% of all patients with portal hypertension. The diagnostic criteria are not yet clearly defined. It has been mentioned in a few case reports; its distribution was mainly duodenal and less frequently gastric. Here, a patient with type 2 diabetes and liver cirrhosis was hospitalized for vomiting, abdominal pain, and melena. The patient was admitted to the intensive care unit for stabilization and urgent esophagogastroduodenoscopy (EGD). EGD revealed a single antral polyp occluding the pyloric ring which was the cause of gastric outlet obstruction. Complete debulking by argon plasma was done which improved gastric outlet obstruction and melena. We conclude that argon plasma coagulation is a safe, rapid, and effective method for treating portal hypertensive polyposis.

RESUMO

PURPOSE: To assess diagnostic validity and reproducibility of Thyroid Imaging Reporting and Data System (TI-RADS) for interpretation of thyroid nodules by thyroid ultrasonography (US). METHOD: A prospective multicentre study initially included 557 patients with clinically suspected thyroid nodules. After exclusion, a final cohort of 380 patients with 948 thyroid nodules detected by US were enrolled. Based on American College of Radiology (ACR) TI-RADS, three radiologists analysed all US examinations independently and assigned a TI-RADS category to each thyroid nodule. The final diagnosis was based on cytology which was used as reference standard for calculating diagnostic performance of TI-RADS for predicting malignant thyroid nodules. The Fleiss and weighted kappa (κ) statistics were applied to assess inter-observer agreement of morphological features and TI-RADS scoring results for thyroid nodules. Additionally, we made a simple screening among referring clinicians to assess the clinical response to application of TI-RADS. RESULTS: A total of 948 thyroid nodules were evaluated; 136 (14.3%) were malignant, and 812 (85.7%) were benign. The papillary carcinoma was the most common malignant thyroid nodules (81.6%). The best cut-off value for predicting malignant thyroid nodules was > TR3. On a lesion-based analysis, the TI-RADS had a sensitivity, specificity, and an accuracy of 98.3%, 90.9%, and 92.1%, respectively when regarding those thyroid nodules classified as > TR3 for predicting malignancy. The inter-observer agreement of the TI-RADS category was good (κ = 0.636). Ninety percent of referring clinicians accept TI-RADS. CONCLUSIONS: TI-RADS improves diagnostic performance of US for predicting malignant thyroid nodules with high validity and high reproducibility.

RESUMO

BACKGROUND: Insulin resistance (IR) in cases of non-alcoholic fatty liver disease (NAFLD) is connected to remarkable liver cell inflammation and cardiovascular complications. Given the prevalence of NAFLD and its association with potential sequels, there is a strong need for an accurate non-invasive tool to monitor the progression of NAFLD. METHODS: 272 patients with NAFLD and cardio-metabolic risk factors were tested for HOMA-IR, mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR), uric acid, ferritin, lipid profile, liver stiffness measurement (LSM), controlled attenuation parameter (CAP) by fibroscan and carotid intima media thickness (CIMT). Liver biopsy was performed to validate the results.100 healthy controls were selected. A score was constructed and applied to a validation group (n = 61). RESULTS: Logistic regression revealed that significant fibrosis and cardiovascular risk in NAFLD were independently associated with AST/ALT ratio (p = 0.000), GGT (p = 0.000), CIMT (p = 0.001), uric acid (p = 0.000), VLDL (p = 0.000), HOMA-IR (p = 0.000), ferritin (p = 0.000) CAP (p = 0.000), LSM (p0.000). A non-invasive model was formulated by which a value > 15 was accurate in identification of advanced fibrosis and cardiovascular risk with a sensitivity of 97.3%, specificity 97%. CONCLUSION: The score correlated well with the results of liver biopsy and can be repeated with great flexibility to assess severity of NAFLD.

RESUMO

OBJECTIVES: Failure of Helicobacter pylori eradication is documented in 20% of patients. Some patients show a negative faecal antigen test (FAT) with persistent symptoms after therapy. The aim of this study was to detect occult H. pylori infection in patients with persistent symptoms despite FAT negativity following therapy. METHODS: A total of 200 symptomatic patients presenting with dyspepsia and positive FAT were treated with H. pylori triple therapy for 2 weeks. Refractory patients received levofloxacin-based salvage therapy. Upper gastrointestinal endoscopy was performed for patients with persistent symptoms despite negative FAT after salvage therapy. Gastric biopsies were exposed to rapid urease test and RFLP-PCR for clarithromycin resistance in domain V of 23S rRNA (2142/2143 point mutations) as well as culture and antimicrobial susceptibility testing (AST). RESULTS: A total of 136 patients responded to classic triple therapy with negative FAT, and 15 patients showed persistent symptoms with positive FAT and received salvage therapy. The remaining 49 patients showed persistent symptoms despite negative FAT, therefore gastric biopsies with rapid urease test were performed. Clarithromycin resistance was confirmed in 12/49 patients (24.5%). Cultures were most commonly susceptible to norfloxacin (n=18), moxifloxacin (n=13), doxycycline (n=11) and amikacin (n=8). Non-responders with negative FAT had moderate or severe fatty liver disease (26.5% and 32.7%, respectively), 40.9% had hepatitis C virus (HCV) infection, and they had significantly higher HOMA-IR and HbA1c. CONCLUSION: Diabetes mellitus, HCV and non-alcoholic fatty liver disease predispose to refractory H. pylori requiring culture and AST.

RESUMO

BACKGROUND: Medical treatment of decompensated cirrhosis due to hepatitis C virus (HCV) remains a clinical challenge even in the era of direct-acting antiviral drugs (DAAs). We evaluated the efficacy and safety of DAAs in the management of HCV genotype 4-related decompensated cirrhosis. METHODS: The study included a treatment group (n = 160) composed of HCV patients with decompensated cirrhosis who received DAAs for 3 months and a matched control group (n = 80) who preferred not to receive DAAs, follow-up was for 24-31 months. RESULTS: In treatment group; there were improvements in platelet count, albumin, CTP (p = 0.001) and MELD scores (p = 0.03), a significant reduction in the frequency of hepatic encephalopathy (HE). SVR was achieved in 90%. Hepatocellular carcinoma (HCC) developed in 10% (n = 18) within 6.8 ± 2.5 months after DAAs, survival was higher in the treated vs. the control group (28.9 ± 0.95 vs. 11.4 ± 2.2 months, p = 0.001). Liver volume by ultrasound at a cutoff 495 ml was predictive of complications after DAAs therapy mainly HCC and reduced survival with sensitivity 93.2%, specificity 72%. CONCLUSION: HCV with decompensated cirrhosis and adequate liver volume had a 90% SVR with improved CTP&MELD and survival. CLINICAL TRIAL: (NCT03547895).

RESUMO

PURPOSE: We investigated the added value of diffusion-weighted imaging (DWI)/apparent diffusion coefficient (ADC) in the categorization of small hepatic observation (≤ 20 mm) detected in patients with chronic liver disease in reference to LI-RADS (liver imaging reporting and data system) classification system. METHODS: We prospectively evaluated 165 patients with chronic liver disease with small hepatic observations (≤ 20 mm) which were previously categorized as LI-RADS grade 3-5 on dynamic contrast-enhanced CT (DCE-CT). All patients were submitted to a functional MRI including DCE and DWI. Using LI-RADS v2017, two radiologists independently evaluated the observations and assigned a LI-RADS category to each observation using DCE-MRI alone and combined DCE-MRI and DWI/ADC. In the combined technique, the radiologists assigned a LI-RADS category based on a modified LI-RADS criteria in which restricted diffusion on DWI was considered a major feature of HCC. We evaluated the inter-reader agreement with Kappa statistics and compared the diagnostic performance of the LI-RADS with two imaging techniques by Fisher's exact test using histopathology as the reference standard. RESULTS: Combined technique in LI-RADS yielded better sensitivities (reader 1, 97% [65/67]; reader 2, 95.5% [64/67]) for HCC diagnosis than DCE-MRI alone (reader 1, 80.6% [54/67], p = 0.005; reader 2, 83.6% [56/67], p = 0.04). The specificities were insignificantly lower in combined technique (reader 1, 88.4% [107/121]; reader 2, 77.7% [94/121]) than in DCE-MRI alone (reader 1, 90.9% [110/121], p = 0.67; reader 2, 79.3% [96/121], p = 0.88). The inter-reader agreement of the LI-RADS scores between combined technique and DCE-MRI was good (κ = 0.765). CONCLUSION: The use of DWI/ADC as an additional major criterion, improved the sensitivity of LI-RADS in the diagnosis of HCC while keeping high specificity.
