Predictors of Frailty in Patients With Liver Cirrhosis.

Introduction Frailty is noticed in a large number of cirrhotic patients with advanced liver disease. Frailty not only disposes cirrhotic patients to increased rates of decompensation and hospitalization but also leads to prolonged hospital stay and increased psychological and social impact, resulting in the delisting of these patients from the transplant list. Therefore, our aim was to identify the factors that are independent predictors of frailty in patients with liver cirrhosis. Methods This cross-sectional study was carried out at the Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation, Karachi, Pakistan, from March 1, 2022, to August 31, 2022. All the patients diagnosed with liver cirrhosis and aged 18-70 years were included in the study. The excluded patients comprised those with disorders that over-estimate frailty such as cardiopulmonary disease and hepatocellular carcinoma. The measurement of the Liver Frailty Index (LFI) was done using the hand grip strength method, timed chair stands, and balance testing. Patients with LFI >4.5 were considered frail. All data was entered and analyzed using IBM SPSS Statistics for Windows, Version 22.0 (Released 2013; IBM Corp., Armonk, New York, United States). Continuous variables were analyzed using the student-t test while categorical variables were analyzed using the chi-square test. Variables with significance on univariate analysis then underwent multivariate analysis to identify the independent predictors of frailty in cirrhotic patients. A p-value < 0.05 was considered statistically significant. Results A total of 132 patients were included in the study. Out of them, 89 (67.4%) were males. On assessment, 51 (38.6%) patients were frail on presentation. On univariate analysis, female gender, advanced age, raised total leucocyte count, increased percentage of neutrophils on peripheral smear, raised serum creatinine, raised total bilirubin, raised prothrombin time, high Child Turcotte Pugh (CTP) score, and high model for end-stage liver disease along with low hemoglobin and low serum albumin levels were statistically significantly associated with frailty in cirrhosis. On multivariate analysis, female gender, age >40 years, CTP>B7, Hemoglobin <10g/dl, and neutrophils >60% on peripheral smear were independent predictors of liver frailty in cirrhotic patients. Conclusion Female gender, advanced age, increased neutrophils on peripheral smear, decreased hemoglobin along with increased degree of liver dysfunction were independent predictors of increased frailty in patients with chronic liver disease.

Pancreatobiliary Lymphadenopathy: Etiology, Location, and Factors Predicting Good Yield of Endoscopic Ultrasound-guided Biopsy.

Introduction: Pancreatobiliary lymphadenopathy (PBL) may be due to a number of benign or malignant causes. Tissue sampling of these lymph nodes (LN) can be possible with the help of endoscopic ultrasound (EUS). Aim of this study was to identify the etiology of the PBL, morphology, and factors predicting good yield of biopsy with EUS. Materials and methods: All patients found to have pancreatobiliary lymph node (PBLN) enlargement (>10 mm) on abdominal imaging and referred for EUS-guided biopsy were included in this prospective observational study. The facility of rapid on-site evaluation (ROSE) was not available. Adequacy of the tissue specimen was assessed by the endoscopist with macroscopic on-site evaluation (MOSE) and then sent to histopathologist for final diagnosis. Factors predicting good yield of biopsy were then analyzed. Results: Of the total 87 patients with PBL, 54 (62.1%) were males. Mean age of the patients was 52.0 (±13.4) and range 18-80 years. The commonest locations of PBL were porta hepatis 37 (42.5%), peripancreatic 24 (27.6%), celiac 16 (18.4%), and others 10 (11.5%). Histological reports showed: neoplastic tissue in 34 (39.1%), non-neoplastic in 20 (23%), normal lymphoid tissue (27.6%) and suboptimal in 9 (10.3%). Among the 34 neoplastic causes, 26 had metastatic adenocarcinoma, 5 had lymphoma, and 3 had metastatic neuroendocrine tumors. Among the 20 non-neoplastic causes, 10 had tuberculosis, 4 had anthracosis, and 6 had other findings. Factors predicting good yield of biopsy were a PBLN size ≥12 mm and satisfactory MOSE on both univariate [PBLN (p = 0.005); MOSE (p < 0.0001)] and multivariate [PBLN (p = 0.011); MOSE (p < 0.0001)] analysis. Conclusion: The commonest etiology of PBLN enlargement was metastatic adenocarcinoma among the neoplastic causes and tuberculosis among the non-neoplastic causes. The most common PBLNs approached by EUS were in portahepatis and peripancreatic regions. A good biopsy yield can be predicted with PBLN size of ≥12 mm and a satisfactory MOSE.

Cytomegalovirus-Associated Colitis as a Cause of Lower Gastrointestinal Bleeding in Kidney Transplant Recipients: A Single-Centered Study.

Introduction Cytomegalovirus (CMV) is the most common viral pathogen affecting patients undergoing solid organ transplantation. It is often the most important infection for patients who have undergone kidney transplantation. Clinical presentations of cytomegalovirus infection range from asymptomatic infection to organ-specific involvement. This study aimed to determine the frequency of cytomegalovirus-associated colitis in kidney transplant recipients (KTRs) presenting with lower gastrointestinal bleeding. Methods After the approval of the ethical review committee of the Sindh Institute of Urology and Transplantation (ERC-SIUT), this cross-sectional study was conducted at the Department of Hepatogastroenterology at the Sindh Institute of Urology and Transplantation from January 2021 to December 2021. All the KTRs (six months after the transplantation) of either gender and aged between 18 and 65 years, presenting with lower gastrointestinal (GI) bleeding as per the operational definition, were enrolled in the study. Those patients who were either unfit for the endoscopy or refused to give consent were excluded from the study. Colonic biopsies were reviewed by a consultant histopathologist for the features of CMV infection. Results A total of 95 renal transplant recipients of either gender or age above 18 to 65 years with lower GI bleeding were included in the study. Among them, 84 (88.4%) were males, while 11 (11.6%) were females. The mean age of the patients included in the study was 37±11 years. The most common presenting complaint was fresh bleeding per rectum, which was observed in 73 (76.8%). The most common findings observed on colonoscopy in KTRs with bleeding per rectum were colonic ulcers and erosions noted in 41 (43.1%) and 36 (37.3%) patients, respectively. On histopathology, CMV colitis was noted in 21 (22.1%) patients. On comparison of different baseline variables, the presence of fresh bleeding per rectum and the presence of both ulcers and erosions on colonoscopy were the factors significantly associated with CMV colitis in KTRs. Conclusion CMV colitis is a prevalent condition in KTRs, presenting with lower GI bleeding. Despite the significant occurrence, the levels of CMV viremia were not associated with CMV colitis, suggesting that diagnosis should rely on histopathological confirmation. Prophylaxis during periods of high immunosuppression is crucial to reducing the incidence of CMV infections and improving both graft function and patient survival.

Anhydroparthenin as a dual-target inhibitor against Sterol C-24 methyltransferase and Sterol 14-α demethylase of Leishmania donovani: A comprehensive in vitro and in silico study.

Parthenium hysterophorus plant has a diverse chemical profile and immense bioactive potential. It exhibits excellent pharmacological properties such as anti-cancer, anti-inflammatory, anti-malarial, microbicidal, and anti-trypanosomal. The present study aims to evaluate the anti-leishmanial potential and toxicological safety of anhydroparthenin isolated from P. hysterophorus. Anydroparthenin was extracted from the leaves of P. hysterophorus and characterized through detailed analysis of 1H, 13C NMR, and HRMS. Dye-based in vitro and ex vivo assays confirmed that anhydroparthenin significantly inhibited both promastigote and amastigote forms of the Leishmania donovani parasites. Both the cytotoxicity experiment and hemolytic assay revealed its non-toxic nature and safety index in the range of 10 to 15. Further, various mechanistic assays suggested that anhydroparthenin led to the generation of oxidative stress, intracellular ATP depletion, alterations in morphology and mitochondrial membrane potential, formation of intracellular lipid bodies, and acidic vesicles, ultimately leading to parasite death. As a dual targeting approach, computational studies and sterol quantification assays confirmed that anhydroparthenin inhibits the Sterol C-24 methyl transferase and Sterol 14-α demethylase proteins involved in the ergosterol biosynthesis in Leishmania parasites. These results suggest that anhydroparthenin could be a promising anti-leishmanial molecule and can be developed as a novel therapeutic stratagem against leishmaniasis.

Diagnostic Accuracy of Narrow-Band Imaging in Predicting Helicobacter pylori Gastritis in Patients With Dyspepsia.

Background Helicobacter pylori (H. pylori) is one of the most prevalent causes of chronic gastritis that can lead to gastric cancer if left untreated. Currently, endoscopy and histology are the gold standard tests for the diagnosis of H. pylori gastritis. Recently, studies have shown the utility of narrow-band imaging (NBI) in predicting H. pylori gastritis. Therefore, we aimed to determine the diagnostic accuracy of NBI in predicting H. pylori gastritis in patients with dyspepsia. Methodology After obtaining approval from the Ethical Review Committee, Sindh Institute of Urology and Transplantation, this cross-sectional study was conducted in the outpatient Clinic of Hepatogastroenterology of the institute. Inclusion criteria involved all patients of either gender aged 18 to 65 years with dyspeptic symptoms. We excluded patients with a history of proton pump inhibitor use within two weeks before endoscopy, heart failure, previous gastrectomy, portal gastropathy, cirrhosis, use of antiplatelet medications, non-steroidal anti-inflammatory drugs or anticoagulant medication, and hemorrhagic or thrombophilia disorders. Each patient underwent endoscopy-guided NBI studies followed by biopsies from the antrum and body of the stomach. Multivariate logistic regression analysis was performed for the type of NBI pattern predicting H. pylori infection. The diagnostic accuracy was obtained individually for each NBI type and then for the presence of either two or all three NBI types in predicting H. pylori gastritis. Results Out of the total 775 patients enrolled in the study, abnormal NBI patterns were observed in 401 (51.7%) patients. The presence of abnormal NBI antral mucosal pattern on endoscopy was significantly associated with H. pylori infection (p < 0.001) with excellent diagnostic accuracy. Among the three NBI types, individually, NBI type III had excellent specificity and better diagnostic accuracy in predicting H. pylori gastritis than the other two types. Furthermore, the presence of all three abnormal NBI patterns (I+II+III) together was significantly associated with the presence of H. pylori gastritis with a sensitivity of 94.54%, specificity of 86.55%, and diagnostic accuracy of 90.32%. Conclusions NBI on endoscopy shows excellent diagnostic accuracy in identifying H. pylori gastritis in patients with dyspepsia. However, multicenter studies are required not only to validate our results but also to predict the pre-cancerous lesions on NBI in patients with H. pylori gastritis.

Etiologies Associated With Elevated Liver Enzymes After Renal Transplant.

OBJECTIVES: One of the most important causes of morbidity and mortality in renal transplant recipients is liver disease. Liver dysfunction is shown in 7% to 67% of kidney transplant recipients. Liver insufficiency accounts for death in up to 28% of kidney transplant recipients. We stratified various etiological factors responsible for elevated liver enzymes in kidney transplant recipients. MATERIALS AND METHODS: We enrolled all patients who fulfilled inclusion criteria. The principal investigator obtained and recorded demographic and clinical information via a standardized form. We reviewed clinical records of kidney recipients with hepatotoxicity during the course of illness, and we analyzed data with SPSS statistical software (version 22). Descriptive statistics were used for continuous and categorical variables. RESULTS: All recipients of living related renal transplants from January 2015 to December 2016 were included in the study (n = 496). We excluded 64 patients with positive serology for hepatitis B or hepatitis C before transplant. Of the remaining 432 patients, 74 (17.1%) had deranged liver enzymes. Forty-one patients (55.4%) had deranged liver enzymes 3 to 4 years after transplant, whereas 23 patients (31.1%) had deranged liver enzymes 4 years after transplant. Liver parenchymal biopsy was performed in 17 patients (23%) to evaluate the etiology. The most common cause of deranged liver enzymes was sepsis, which was seen in 21 patients (28.4%), followed by viral hepatitis, ie, cytomegalovirus hepatitis in 7 (9.5%) and hepatitis C in 6 (8.1%) patients. Other causes included antituberculosis treatment-induced liver injury, autoimmune hepatitis, sinusoidal obstruction syndrome, and nonalcoholic steatohepatitis, observed in 4 patients each (5.4%). CONCLUSION: The most common cause of deranged liver enzymes in patients who received living related renal transplants in our population was sepsis, which can have a substantial effect on graft survival.

Combination therapy of nitazoxanide with oseltamivir compared with oseltamivir in hospitalized patients with seasonal influenza.

Antiviral combinations have been proposed as treatment for influenza in order to increase the antiviral activity by action at different sites of action as well as obviate the emergence of drug resistance to the commonly used antiviral agents like oseltamivir. Nitazoxanide has been found to exhibit anti-influenza viral activity with clinical benefit in a previous study. We recruited 242 cases of SARI, among whon 67 were confirmed to have influenza viral infection. In a randomized blinded fashion, 34 patients received a combination of nitazoxanide and oseltamivir whereas 33 cases received oseltamivir alone. Clinical parameters were followed in both groups and the nasal swabs were re-tested on day 6 for influenza positivity and the cycle threshold (CT) values. No significant differences were observed in terms of time for resolution of fever, other symptoms, and SOFA scores. Nine patients succumbed during the course of the illness that included three in the oseltamivir group and six in the combination group. All but one of those who expired had an underlying co-morbid illness. Our preliminary data suggest that the addition of nitazoxanide does not improve outcomes in hospitalized patients with influenza. Larger studies are recommended for statistically robust conclusions.

Utility of the "BATS" Score in Predicting Choledocholithiasis in Patients With Gall Bladder Stones.

Background and aim The role of expensive, risky, and unnecessary endoscopic interventions can be avoided by the use of non-invasive tests to predict common bile duct (CBD) stones. Therefore, our aim was to identify non-invasive predictors of choledocholithiasis (CL) in patients and further to predict a model and assess its diagnostic accuracy in predicting CL. Methods This cross-sectional study was carried out from June 1, 2020, to December 31, 2021. Patients having gall bladder stones on percutaneous transabdominal sonography and fulfilling intermediate probability criteria of CL were enrolled. These patients then underwent radial endoscopic ultrasound (EUS) followed by endoscopic retrograde cholangiopancreatography (ERCP) for detecting CBD stones. Univariate logistic regression analysis, followed by multivariate logistic regression analysis, was performed to ascertain the independent predictors of CBD stone in patients with intermediate probability. A model was proposed, and the diagnostic accuracy was calculated at an optimal cutoff. The model was then internally validated in the patients with intermediate probability and was also compared with the pre-existing score. Results Out of 131 patients included in the study, CBD stone was noted in 85 (66%) and 88 (67.2%) patients on EUS and ERCP, respectively. On multivariate analysis, high serum bilirubin (>2 mg/dL) and alkaline phosphatase (200 IU) and dilated CBD (>6 mm) on transabdominal sonography at baseline were significant predictors of CBD stone in these patients. Using these variables, a scoring system (BATS score) was developed, which had an area under the receiver operating curve (AUROC) of 0.98 in predicting the presence of CBD stone with a sensitivity of 93.18%, a specificity of 76.74%, and a diagnostic accuracy of 87.79%. In the validation cohort, a BATS score of ≥5 had a diagnostic accuracy of 95.91% in predicting CL. Conclusion The BATS score showed excellent sensitivity and good diagnostic accuracy in predicting the CBD stone with excellent results on internal validation. However, external validation of our results is required to recommend this model on a larger scale.

Role of Endoscopic Ultrasound in Predicting Solid Pancreatic Lesions Using Strain Ratio and Elastography.

Background: Despite advancement in imaging techniques, the diagnosis of solid pancreatic lesions (SPLs) remains challenging. The latest advancement in elastography permits the quantitative measurements of the average elasticity of a lesion. Therefore, our main aim of this study was to determine the utility of endoscopic ultrasound-guided elastography (EUS-EG) and strain ratio (EUS-SR) in predicting SPLs. Materials and methods: This cross-sectional study was performed at the Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation. All patients with radiological diagnosis of SPLs underwent EUS-EG, followed by strain ratio (SR) measurement and targeted pancreatic fine needle lesion biopsy (FNB). Area under the receiver operating curve (AUROC) was obtained for SR and combined elastography and SR and at an optimal cutoff, diagnostic accuracy was obtained in predicting the nature of SPLs. Results: A total of 52 patients were included in this study. Out of them, 32 (61.5%) patients were males while 20 (38.5%) were females. The mean age was 50.8 ± 12.5 years. Twenty-four (46.2%) patients had malignant pancreatic lesions. Among malignant lesions, the most common etiology was pancreatic adenocarcinoma seen in 18 (34.6%) patients. Out of 28 (53.8%) patients with benign lesions, 14 (26.9%) patients had inflammatory disease. Area under the receiver operating curve was obtained for both SR alone and SR combined with elastography score in differentiating benign from malignant SPLs which was 0.832 (p-value < 0.001) for SR alone and a slightly higher for combined SR with elastography (AUROC-0.839)(p-value < 0.001). At an optimal cutoff of SR of >17, the sensitivity was 94.8% and the diagnostic accuracy was 74% in predicting SPLs. While, when SR and elastography were combined together, the sensitivity increased to 96% with a diagnostic accuracy of 75%. Conclusion: Combined EUS-EG and SR were accurate in diagnosing malignant pancreatic lesions with a diagnostic accuracy of 75% providing additional diagnostics information before biopsy. However, multicentric studies with larger sample sizes are required for the validation of our results to determine the utility and diagnostic accuracy of EUS-SR in defining the characteristic of pancreatic lesions.

Correlation of Model for End Stage Liver Disease (MELD), MELD-Sodium (MELD-Na), and Child-Turcotte-Pugh (CTP) Score With Frailty in Patients With Hepatitis C Virus (HCV) Related Cirrhosis.

INTRODUCTION: The model for end stage liver disease (MELD), model for end stage liver disease-sodium (MELD Na), and Child-Turcotte-Pugh (CTP) score are independent predictors of mortality in cirrhotic patients. Approximately 43% of cirrhotic patients with advanced disease are frail and can have detrimental effects on the disease prognosis and survival including delisting from the transplant list and increased risk of post-transplant complications. Therefore, our aim was to determine the correlation of MELD, MELD-Na, and CTP score with frailty in patients with hepatitis C virus (HCV) related cirrhosis. METHODS:  This cross-sectional study was conducted at the Department of Hepato-gastroenterology, Sindh Institute of Urology and Transplantation from 1st January 2022 to 30th June 2022. All the patients of either gender aged between 18 and 70 years with serological evidence of HCV and features of cirrhosis on ultrasound abdomen were included in the study. Patients with conditions over estimating frailty were excluded from the study. Liver Frailty Index (LFI) was calculated using grip strength measured in kilograms, timed chair stands, and balance testing. CTP and MELD-Na scores for each patient were also recorded. All the data were analyzed using SPSS version 22.0 (IBM Corp., Armonk, NY). The correlation of MELD, MELD-Na, and CTP with LFI was analyzed using the Pearson correlation coefficient and a p-value < 0.05 was considered statistically significant. RESULTS:  A total of 274 patients were included in the study. Out of them, 185 (67.5%) were males. The mean CTP score was 8.1 + 2.1, MELD score of 13.6 + 7.1, MELD-Na score of 15 + 6.6, and LFI of 4.1 + 0.83. LFI was found to be weakly correlated with MELD (r = 0.278) (p < 0.001), MELD-Na score (r = 0.41) (p < 0.001), and CTP score (r = 0.325) (p < 0.001). CONCLUSION:  Weak correlation was noted between LFI, CTP, MELD, and MELD-Na scores in HCV-associated chronic liver disease. Therefore, frailty along with MELD, MELD-Na, and CTP must be assessed before considering the patients for liver transplantation.

Brachial artery trauma as a complication of bicep muscle injury.

We describe a rare case of injury to a branch of the brachial artery in a 48-year-old man with a bicep musculotendinous injury. His presenting symptoms included severe pain, swelling, and paresthesias in the right upper extremity. Examination revealed significant soft tissue swelling with ecchymoses in the right upper arm with diminished palpable pulses. Imaging revealed a biceps muscle injury along with active arterial extravasation of a branch of the deep brachial artery. Interventional radiology successfully performed coil embolization. Bicep musculotendinous injury is typically characterized by pain, swelling, and decreased strength. Rarely, complications such as compartment syndrome have been reported. Brachial arterial injury has not been implicated in the setting of this entity, especially in the absence of blunt or penetrating trauma, until our current patient's presentation.

Role of "HinCh Score" as a Non-invasive Predictor of Post-endoscopic Retrograde Cholangiopancreatography Cholangitis.

Introduction: Post-endoscopic retrograde cholangiopancreatography (ERCP) cholangitis (PEC) is associated with increased morbidity and mortality in patients ERCP. The aim of the present study was to analyze the predictors of PEC and to formulate a predictive model for early diagnosis and management. Materials and methods: It was a cross-sectional study that was carried out at the Sindh Institute of Urology and Transplantation from September 2019 to June 2021. All patients aged between 18 and 75 years and undergoing ERCP due to obstructive jaundice were included. Patients with altered biliary anatomy, history of hepatobiliary surgery, and concurrent sepsis were excluded. Endoscopic retrograde cholangiopancreatography intervention was performed by an expert gastroenterologist. Laboratory parameters (total leukocyte count, total bilirubin, alanine transaminase) and patient temperature were checked on admission, at 12 hours, 24 hours, and 36 hours after ERCP to document PEC. Results: A total of 349 patients were included in the study. Among them, 176 (50.4%) patients were males. Common bile duct (CBD) stricture was the most common indication of ERCP seen in 148 (42.4%) patients followed by CBD stone and cholangiocarcinoma in 108 (30.9%) and 48 (13.8%) patients, respectively. The most common presenting complaint was jaundice noted in 300 (86%) patients followed by right hypochondrial pain in 280 (80.2%) and weight loss in 194 (55.6%) patients, respectively. Post-ERCP cholangitis developed in 251 (71.9%) patients. On univariate analysis, age >50 years, female gender, right hypochondrial pain, fever, bilirubin >5 mg/dL on admission, CBD stricture on ERCP, TLC of >10,000 cells/L at 12 hours, 24 hours, and 36 hours post-ERCP and rise in ALT >50 IU 24 and 48 hours post-ERCP were significantly associated with PEC. While on multivariate analysis, female gender, bilirubin >5 mg/dL on admission, CBD stricture on ERCP, post-ERCP fever, and rise in TLC of >10000 cells/L at 24 hours post-ERCP were independently associated with PEC. HinCh score was formulated and was found to be significantly associated with the presence of cholangitis. Area under the receiver operating characteristics (AUROC) of HinCh score was 0.74 and at cutoff of ≥4, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of HinCh were 81.67%, 59.18%, 83.67%, and 55.71%, respectively with a diagnostic accuracy of 75.36%. Conclusion: The performance of HinCh score in predicting PEC was accurate in 86% of the patients. However, further studies are needed to validate the score.

Clinical Characteristics and Comparison of Different Prognostic Scores in Wilson's Disease.

Aim: Wilson's disease (WD) is a rare autosomal recessive disease, that can involve any organ of the body, the main ones being the liver and the brain. These patients can have varied presentations, ranging from having no symptoms to having neurological manifestations to features of chronic liver disease (CLD). Those patients that end up having CLD are prognosticated via the Child-Turcotte-Pugh (CTP) score and the Model for End-stage Liver Disease (MELD) score. However, two specific scores exist for prognostication in patients having WD, namely, the Nazar score and the Dhawan score. However, these are yet to be validated nor has their use been implemented in clinical practice. Materials and methods: Our study involved 65 patients with WD, comprising both the pediatric and the adult population. We aimed at evaluating the clinical manifestations the lab parameters and the management of these patients. Furthermore, we tried validating the Nazar and the Dhawan score and later compared them with the CTP and the MELD score, which are well-known prognostic tools in CLD. Results: Our patients were subdivided into the pediatric (more than 50%) and the adult group. The most common presenting complaint noted in both groups was abdominal distension. Values of the urine copper and serum ceruloplasmin did not defer between the pediatric and adult patients. Hepatic involvement is frequently seen in the pediatric age-group. Also, CTP class C was chiefly seen in pediatrics 17/33 (51.5%), while CTP class B was in adults 13/32 (40.6%). The mean Nazar score was 3 ± 3, while the mean Dhawan score was 5 ± 4. The main treatment offered for both groups was zinc along with penicillamine. Conclusion: Our study showed the Dhawan score was comparable to the CTP and the MELD score in terms of predicting the disease severity of WD in our patient population.

The Use of Albumin-to-bilirubin Score in Predicting Variceal Bleed: A Pilot Study from Pakistan.

Variceal hemorrhage is a serious consequence of patients having chronic liver disease (CLD). Various scores exist that predict the outcome for non-variceal bleed. However, only a few scores evaluate patients with variceal bleed. We, in our study, evaluated 48 cirrhotics who presented with variceal gastrointestinal (GI) bleed over a period of 3 months. Majority of these were males and the most common etiology was hepatitis C infection. The main presenting complaints were hematemesis seen in 39.6% followed by hematemesis and melena in 31.25%. Most bleeding episodes were secured via banding in 62.5% followed by injection of histoacryl in 12.5%. Finally, Child-Turcotte-Pugh (CTP), model for end-stage liver disease (MELD), albumin-to-bilirubin (ALBI), and the ABC score were applied and none correlated with the presence of esophageal varices. However, the ALBI score did correlate with the presence of tachycardia in our study, a pertinent sign of upper GI bleed. How to cite this article: Majid Z, Khan SA, Akbar N, et al.

In-vitro cytotoxicity in relation to chemotypic diversity in diploid and tetraploid populations of Gentiana kurroo Royle.

ETHNOPHARMACOLOGICAL RELEVANCE: Gentiana kurroo is a multipurpose critically endangered medicinal herb prescribed as medicine in Ayurveda in India and exhibits various pharmacological properties including anti-cancer activity. The species is rich repository of pharmacologically active secondary metabolites together with secoiridoidal glycosides. AIM OF THE STUDY: The study aimed to investigate the chemical diversity in different populations/cytotypes prevailing in G. kurroo to identify elite genetic stocks in terms of optimum accumulation/biosynthesis of desired metabolites and having higher in-vitro cytotoxicity potential in relation to chemotypic diversity. MATERIAL AND METHODS: The wild plants of the species were collected from different ranges of altitudes from the Kashmir Himalayas. For cytological evaluation, the standard meiotic analysis was performed. The standard LC-MS/MS technique was employed for phytochemical analysis based on different marker compounds viz. sweroside, swertiamarin, and gentiopicroside. Different tissues such as root-stock, aerial parts, and flowers were used for chemo-profiling. Further, the methanolic extracts of diploid and tetraploid cytotypes were assessed for cytotoxic activity by using MTT assay against four different human cancer cell lines. RESULTS: The quantification of major bioactive compounds based on tissue- and location-specific comparison, as well as in-vitro cytotoxic potential among extant cytotypes, was evaluated. The comprehensive cytomorphological studies of the populations from NW Himalayas revealed the occurrence of different chromosomal races viz. n = 13, 26. The tetraploid cytotype was hitherto unreported. The tissue-specific chemo-profiling revealed relative dominance of different phytoconstituents in root-stock. There was a noticeable increase in the quantity of the analyzed compounds in relation to increasing ploidy status along the increasing altitudes. The MTT assay of methanolic extracts of diploid and tetraploid cytotypes displayed significant cytotoxicity potential in tetraploids. The root-stock extracts of tetraploids were highly active extracts with IC50 value ranges from 5.65 to 8.53 µg/mL against HCT-116 colon cancer. CONCLUSION: The chemical evaluation of major bioactive compounds in diverse cytotypes from different plant parts along different altitudes presented an appreciable variability in sweroside, swertiamarin, and gentiopicroside contents. Additionally, the concentrations of these phytoconstituents varied for cytotoxicity potential among different screened cytotypes. This quantitative difference of active bio-constituents was in correspondence with the growth inhibition percentage of different tested cancer cell lines. Thus, the present investigation strongly alludes towards a prognostic approach for the identification of elite cytotypes/chemotypes with significant pharmacological potential.

Analysis of dynamic hepatobiliary contrast-enhanced MRI signal intensity after Yttrium-90 radioembolization with glass microspheres for the treatment of hepatocellular carcinoma.

PURPOSE: To analyze hepatobiliary specific contrast agent (HBA) dynamic MRI signal intensity (SI) differences between treated liver (TL) and untreated liver (UL) parenchyma in patients following transarterial radioembolization (TARE) for hepatocellular carcinoma (HCC) using yttrium-90 containing glass microspheres. MATERIALS: This was a single institution retrospective study of patients with HCC treated with lobar or segmental TARE who received pre- and post-treatment HBA multiphase MRI within a 3-year period. Patients with prior locoregional therapies or multiple TAREs were excluded. SI was obtained by drawing a 2D ROI on T1-weighted non-contrast, arterial (25 s.), portal venous (60 s.), transitional (180 s.), and hepatobiliary (HB) (1200 s.) phase sequences in the (TL) angiosome and UL. HB phase signal enhancement characteristics were correlated with TARE dose thresholds (< 120 Gy, 120-190 Gy, and > 190 Gy) using the medical internal radiation dose (MIRD) methodology. RESULTS: 282 patients received TARE using glass microspheres during the study period and 58 patients who met inclusion criteria were analyzed. Median dose was 141.5 Gy MIRD [IQR 122.0, 161.5; range 100-540 Gy]). Statistically significant differences were present between treated and non-treated liver on non-contrast (- 28.0, p = 0.003), arterial (38.5, p = 0.013), and HB phases (- 95.8, p ≤ 0.001). Median follow-up time to furthest post-treatment MRI was 6 months (range 3-11 months). There was no significant SI difference on portal venous or transitional phases. HB phase SI changes in the TL compared to UL were significant at all TARE dose thresholds (p < 0.05). CONCLUSIONS: SI differences between treated and untreated liver after TARE are most significant on the HB phase and present at all evaluated dose levels at a median of 6 months after treatment. These findings support the parenchymal ablative potential for TARE and the necessity to consider liver function loss within targeted liver volumes.

Use of sofosbuvir based regimen in patients with end-stage renal disease and chronic hepatitis C; an open label, non-randomized, single arm, single center study from Pakistan.

AIM: we aimed to determine the virological response and safety of Sofosbuvir-based direct-acting antiviral agents (DAAs) in chronic hepatitis C (CHC) patients on long-term hemodialysis (HD). BACKGROUND: With the advent of interferon-free DAAs, the treatment of CHC has been revolutionized. Pakistan is among the countries where novel sofosbuvir (SOF)-free antiviral agents are not available. METHODS: This non-randomized, single-arm, open-label study enrolled all HD patients with chronic HCV infection after informed consent. They were treated with SOF in combination with Ribavirin (RBV) with either interferon (IFN group) or daclatasvir (DAC group), with the virological response assessed according to standard guidelines. Data were analyzed using SPSS version 20.00. RESULTS: Out of 133 patients, the majority (72.9%) were males with the mean age of 31.92 ± 9.88 years. Most patients (50.3%) had HCV genotype (GN) 1, followed by GN 3 in 42.9%, 4 in 1.48% and 2 in 0.7%, while mix GN was documented in 6 (4.4%) patients. Among these, 60 (45.1 %) patients received standard SOF, IFN, and RBV (IFN group) and 73 (54.9 %) received SOF, DAC and RBV (DAC group). End of treatment and sustained virological response at 12 weeks post-treatment were achieved in 133 (100%) and 129 (97 %) patients, respectively. The adverse effects were anemia in 58 (43.6 %) patients and elevated alanine transaminases in 11 (8.1%) patients. CONCLUSION: SOF in combination with either IFN or DAC is an equally efficacious and effective treatment regimen for patients on maintenance HD, especially in resource-poor countries.

Combination of vitamin C, thiamine and hydrocortisone added to standard treatment in the management of sepsis: results from an open label randomised controlled clinical trial and a review of the literature.

Background: Combination of vitamin C, hydrocortisone and thiamine have recently been used in sepsis but data of efficacy are conflicting and no data are available from developing countries. We sought to study the effect of addition of this combination to standard care in patients with sepsis/septic shock in a north Indian setting.Methods: In a prospective, open label, randomised fashion, 100 patients with sepsis/septic shock were recruited to receive either standard therapy alone (control group, n = 50) or a combination of vitamin C, thiamine and hydrocortisone (treatment group, n = 50) in addition. The patients were followed for various clinical and laboratory parameters, in-hospital and 30-day mortality, duration of vasopressor use, lactate clearance, duration of hospital stay, and change in serum lactate and the SOFA score over the first 4 days.Results: The 2 groups were matched for basic characteristics. The in-hospital mortality (28% in controls and 24% in treatment group, p = .82) and 30-day mortality (42% in controls and 40% in treatment group, p = 1.00) was not significantly different in the 2 groups. However, there was a significant difference in duration of vasopressor use (96.13 ± 40.50 h in control group v/s 75.72 ± 30.29 h in treatment group, p value = .010) and lactate clearance (control group: 41.81% v/s treatment group: 56.83%, p value =.031) between 2 groups.Conclusions: Addition of vitamin C, hydrocortisone, and thiamine into standard care of sepsis does not improve in-hospital or 30 day mortality. However lower vasopressor use and faster lactate clearance is observed with treatment.

Kaposi Varicelliform Eruption Associated With Chickenpox in a Liver Transplant Recipient.

A 43-year-old male patient developed varicella virus (chickenpox) 4 months after receiving a liver transplant. Within 5 days of complete recovery, he presented with widespread cutaneous vesicular eruptions involving the face, back, abdomen, and upper extremities. Tzanck smear showed ground glass inclusions in the nuclei of multinucleated giant cells, suggestive of viral pathology. The patient was subsequently diagnosed with Kaposi varicelliform eruption, a rare dermatologic emergency. He was treated with high-dose intravenous acyclovir and fully recovered.
