Persistent varices in cured patients: Understanding the role of hepatic venous pressure gradient

Background & Aims

Etiologic factor removal (ER) drives recompensation and improves portal hypertension in cirrhosis. Esophageal varices (EV) and portosystemic shunts (PSS) have been found in patients despite hepatic venous pressure gradient (HVPG) dropping below 10 mmHg after ER, questioning HVPG accuracy in reflecting true portal pressure in the setting of ER. We aim to evaluate the correlation of HVPG with direct portal pressure (DPP) in patients with persistence of EV after ER despite HVPG <10 mmHg.

Methods

This is a bicentric 'proof of concept' study evaluating HVPG and ultrasound-guided percutaneous DPP in patients with HCV or alcohol-related cirrhosis with persistent varices and HVPG <10 mmHg after at least 5 years of ER.

Results

Seven patients with HCV and three with alcohol-related cirrhosis with persistent varices and HVPG <10 mmHg after at least 5 years of ER were included. At evaluation, all patients had a patent portal vein and were compensated. The median platelet count was 129.5 (IQR 95-145) × 109/ml, and the median liver stiffness measurement was 16.15 (IQR 14.4-22.3) kPa. In five patients, EV remained the same size (two large and three small), and five downsized to small after ER. Wedge hepatic vein pressure (median 19 [IQR 16.5-20] mmHg) and portal pressure (median 18 [IQR 15-19.5] mmHg) had an excellent correlation (R = 0.93, p <0.0001). Portal pressure gradient (PPG) confirmed the absence of clinically significant portal hypertension as identified by HVPG across all the patients.

Conclusions

HVPG accurately reflects PPG in the context of HCV and alcohol-related cirrhosis regression. After ER, EV may persist despite HVPG <10 mmHg. The benefit of prophylaxis in patients with EV and HVPG <10 mmHg is unknown. Future studies with clinical endpoints are needed to validate our findings.

Impact and implications

Despite a favorable evolution after the removal of the etiologic factor, varices persist in some patients, and there is a lack of concise guidelines for the evaluation and management of portal hypertension in this population. Our research underscores the persistence of varices in the absence of clinically significant portal hypertension and significantly demonstrates the accuracy of hepatic venous pressure gradient (HVPG) in reflecting portal vein pressure in this specific patient group. These findings emphasize the crucial role of HVPG in the assessment of portal hypertension after etiologic factor removal and lay the groundwork for further investigation into clinical outcomes and the necessity of non-selective beta-blockers in individuals with persistent varices after the removal of etiologic factor.

Prognosis of spontaneous bacterial peritonitis in patients with hepatocellular carcinoma

BACKGROUND

Hepatocellular carcinoma (HCC) is the fourth leading cause of death from cancer worldwide. Spontaneous bacterial peritonitis (SBP) is associated with poor prognosis. This study aimed to evaluate risk factors, differences in clinical characteristics and prognosis of SBP in patients with HCC in comparison with non-HCC patients.

METHODS

This study was conducted on patients with cirrhosis who were admitted to hospital with SBP. The patients were divided into two groups: SBP group with HCC (n = 150) and SBP group without HCC (n = 250).

RESULTS

Men and women accounted for 72% and 28% (n = 108 and 42, respectively) of the population in SBP group with HCC with mean age 55.8 ± 13.1 years. They accounted for 68.4% and 31.6% (n = 171 and 79, respectively) in the SBP group without HCC with mean age 56.8 ± 10.5 years. In-hospital mortality was 25.3% in the SBP group with HCC and 18.8% in SBP group without HCC. Gastrointestinal bleeding was the most common cause of death in both groups. No significant difference was observed in patient outcomes between the two studied groups. The deceased patients had significantly higher levels of leukocytes and neutrophils in ascitic fluid as well as a higher frequency of positive culture results than in patients who survived (p < 0.001). However, there was no significant difference in protein level in ascitic fluid or causative organism between patients who survived and those who died (p = 0.63 and 0.19, respectively).

CONCLUSIONS

Prognosis of SBP in patients with HCC seemed similar to that in patients without HCC.

A multicentric and nationwide predictive study role of T cell sub-population in the prevalence and prognosis of cryoglobulinemia among genotype 4 chronic hepatitis C patients

The infection caused by the hepatitis C virus (HCV) is a significant global health concern. The prevailing genotype of HCV in Egypt is 4a, commonly referred to as GT-4a. A significant proportion exceeding 50% of patients infected with HCV experience extrahepatic manifestations (EHMs), encompassing a diverse range of clinical presentations. These manifestations, including essential mixed cryoglobulinemia (MC), can serve as initial and solitary indicators of the disease. The complete understanding of the pathogenesis of EHM remains unclear, with autoimmune phenomena being recognized as the primary causative factor. In this study, we examined the predictive significance of T-cell subpopulations in relation to the occurrence and prognosis of cryoglobulinemia in HCV patients. A total of 450 CHC genotype four treatment naïve patients were enrolled in this analytic cross-sectional study after thorough clinical, laboratory, and radiological examinations. All patients underwent laboratory investigations, including testing for cryoglobulin antibodies and measurements of CD4 and CD8 levels; two groups were described according to their test results: Group 1 consists of patients who have tested positive for cryoglobulin antibodies and Group 2 consists of patients who have tested negative for cryoglobulin antibodies. The exclusion criteria encompassed individuals with HIV infection or chronic HBV infection. Additionally, pelvi-abdominal ultrasonography was performed. Our study included 450 treatment naïve CHC patients (59% male, mean age 50.8 years). The patients were categorized according to their cryoglobulin antibodys test results into two groups: group A, CHC patients with cryoglobulin antibodies (Abs) negative (364 patients), and group B, CHC patients with cryoglobulin Ab positive (86 patients). Group B demonstrated a higher average age, elevated international normalized ratio, more prolonged duration of HCV infection, lower albumin, higher alanine aminotransferase, higher aspartate aminotransferase, higher bilirubin, lower CD8, lower CD4, and lower CD4:CD8 ratio. In contrast, 27 out of 86 (31.40%) patients in group B had symptoms; 85.8% had purpura and arthralgia, 74.3% had paresthesias, 86.7% had weakness, and 12.2% had non-Hodgkin's lymphoma. The levels of CD4 and CD8 were found to be decreased in chronic HCV patients with MC. T-cell subpopulation serves as a reliable indicator for assessing the prevalence and prognosis of MC in individuals with genotype 4 chronic hepatitis C. However, additional research is needed to further understand the development and spread of various emerging infectious diseases. Nevertheless, it is noteworthy that a critical threshold may exist beyond which EHM reaches a point of no return.

Association between thrombocytopenia and the severity of Covid-19 infection among hospitalized Egyptian patients

Background

COVID-19, which is caused by the corona virus 2 that causes severe acute respiratory syndrome, causes a respiratory and systemic illness that in 10–15% of patients escalates to a severe form of pneumonia. Thrombocytopenia is frequent in patients with COVID-19. We aimed to evaluate the association between thrombocytopenia and the severity of COVID-19 infection in hospitalized patients.

Methods

A cross-sectional study was done on 800 Egyptian patients with confirmed covid-19 infection. They were divided into Group I (Mild): 200 symptomatic patients meeting the case definition for COVID-19 without radiological evidence of pneumonia or hypoxia. Group II (Moderate): 200 patients with clinical signs of non-severe pneumonia and radiological evidence of pneumonia. Group III (Severe): 200 patients with clinical signs of pneumonia plus: respiratory or lung dysfunction. Group IV: 200 critically ill patient in ICU: Acute respiratory distress syndrome (ARDS).

Results: there was a highly statistically significant difference between the studied groups regarding thrombocytopenia (p < 0.001). Thrombocytopenia was statistically higher in severe and critically ill patients. In addition, a statistically significant difference found in outcome among the studied groups (p < 0.05) {critically ill (40%), severe (17.5%)}. The most common cause of death was respiratory failure, which occurred in 28 severe patients (80%) and 65 critically ill patients (81.25%), followed by hemorrhage due to thrombocytopenia, which occurred in 7 severe patients (20%) and 15 critically ill patients, respectively (18.75%).

Conclusion

The Platelet count is a straightforward, inexpensive, as well as easily available laboratory parameter that is frequently linked to severe covid-19 infection and a significant death risk.

A cross-sectional study of gastrointestinal manifestations in COVID-19 Egyptian patients

BACKGROUND

The latest novel corona virus disease (COVID-19) pandemic shows a significant health concern. We aimed to study the prevalence of gastrointestinal symptoms among COVID-19 Egyptian patients.

METHODS

A cross-sectional study was carried out on 860 patients with COVID-19 infection classified according to Ministry of Health Program (MOHP) into three groups (280 patients with mild infection, 258 patients with moderate disease and 322 patients with severe disease). All patients were subjected to medical history, clinical examination, laboratory investigations, high-resolution computed tomography chest (HRCT chest) and other investigations when needed in some patients e.g., upper gastro-intestinal (GI) endoscopy, abdomino-pelvic ultrasound and ECHO.

RESULTS

Gastro-intestinal symptoms were present in 27.2% of the studied patients. The most common reported GIT symptoms were vomiting, diarrhea, abdominal/gastric pain, followed by nausea. GIT symptoms presence was significantly higher in severe cases in comparison to mild or moderate cases. C-reactive protein (CRP), serum ferritin, Aspartate aminotransferase (AST), bilirubin, and creatinine were significantly associated with the presence of GI symptoms.

CONCLUSIONS

GI symptoms are prevalent among COVID-19 patients, the most common were vomiting and diarrhea and were associated with COVID-19 severity.

Should we continue surveillance for hepatocellular carcinoma and gastroesophageal varices in patients with cirrhosis and cured HCV infection?

Hepatocellular carcinoma (HCC) and variceal bleeding are among the most common causes of liver-related mortality in patients with hepatitis C virus (HCV)-induced cirrhosis. Current guidelines recommend HCC and gastroesophageal varices (GEV) surveillance in patients with HCV infection and cirrhosis. However, since the recent introduction of direct-acting antivirals, most patients with cirrhosis are now cured of their chronic HCV infection. As virological cure is considered to substantially reduce the risk of cirrhosis-related complications, this review discusses the current literature concerning the surveillance of HCC and GEV in patients with HCV-induced cirrhosis with a focus on the setting following sustained virological response.

Red cell distribution width as a predictor of outcome in hospitalized cirrhotic patients

BACKGROUND

A systemic inflammatory response syndrome (SIRS) is linked to red cell distribution width (RCDW), which produces pro-inflammatory signals that act directly on hematopoietic stem cells in the bone marrow. This stimulation may cause alterations in the membrane of red blood cells (RBCs), as assessed by RCDW, which have been linked to increased morbidity and death in a number of systemic disorders.

AIM

This study aims to evaluate RCDW as a predictor of outcome in hospitalized cirrhotic patients.

METHODS

This prospective cross-sectional study was conducted on 1000 patients. The outcome was assessed by days of hospitalization; mortality in hospitalized patients or during short-term follow-up (3 months) and rehospitalization during follow-up of 6 months.

RESULTS

Male represented 69.6%. Mean age was 57.67 ± 13.07 years old. Baseline co-morbidities were recorded as the presence of diabetes mellitus (200 patients) and hypertension (400 patients). Hepatitis C virus was the commonest etiology of the diseased liver (90%). Child-Pugh classes A, B and C of studied patients represented (21.2%, 38.8% and 40%). The survived patients during follow-up represented 63.3%. Area under the curve for RCDW was 0.923 (95% CI, 0.904-0.943), 0.910 for C-reactive protein (95% CI, 0.890-0.930), 0.904 for Hb (95% CI, 0.883-0.925) and 0.903 for platelets (95% CI, 0.882-0.924). RCDW cutoff point at 21.35 for predicting survival had sensitivity 93%, specificity 91%, accuracy 92%, positive predictive value 85 and negative predictive value 96. Regression analysis revealed a significant positive association between both RCDW and white blood cells with mortality.

CONCLUSION

RCDW could provide useful information for predicting the length of hospitalization and survival in hospitalized cirrhotic patients.
