Cholestasis is defined as stagnation or a marked reduction in bile secretion and flow. Cholestatic jaundice can thus be classified as intrahepatic or extrahepatic cholestatic, depending on the level of obstruction to bile flow. It is important to recognize the complications of cholestatic in patients with chronic cholestatic liver disease.
The two most common complications of cholestasis are pruritus and fatigue, with the former being the most responsive to treatment. Cholestyramine is the first-line treatment for cholestatic pruritus. Rifampicin and oral opioid antagonist naltrexone are extremely effective second-line treatments. To date, there are no specific treatments for chronic cholestatic fatigue management. Osteoporosis is a complication that can arise in chronic cholestatic conditions. It appears to be more prominent in individuals with cholestatic liver disease than in patients with other chronic liver diseases with an increased risk of fracture. The evaluation of osteoporosis in individuals with chronic cholestasis is similar to that in the general population. Antiresorptive agents such as bisphosphonates are the first-line treatment choice for osteoporosis in patients with chronic cholestasis. Other less common complications include dyslipidemia, fat-soluble vitamin deficiency, and steatorrhea.
Understanding and treating these conditions can have a significant impact on the morbidity and quality of life in this group of patients. This review aimed to provide further information about the complications of chronic cholestasis and to highlight evidence-based test practices for the evaluation and effective management of these complications.

Gastric cancer is one of the most common cancers worldwide. Human bocavirus (HBoV), a recently isolated virus, has been investigated for its role in many respiratory and enteric diseases. Few studies have reported its presence in solid tumors, such as lung and colon cancers. The aim of this study was to detect the presence of the HBoV1 genome in gastric adenocarcinoma, which has not yet been evaluated.

Formalin-fixed paraffin-embedded (FFPE) blocks of 189 gastric tumors and 50 blocks of non-tumor gastric tissue products from elective weight reduction operations were collected. DNA extraction and real-time polymerase chain reaction (PCR) were performed for HBoV1 detection. DNA sequencing was performed using ABI Genetic Analyzer series 3500.

The mean age of the patients was 60 ± 13.33 years. Tumors were more common in males than females (2.5/1). HBoV1 PCR was positive in 34 (18%) cases of GC and 10 (20%) cases of chronic gastritis (P > 0.05). There was no association between age, sex, stage, and histologic subtype of the tumor and HBoV1 positivity (P > 0.05) in tumor samples. The rate of intestinal metaplasia and presence of lymphoid stroma were also not more frequent in HBoV1-positive tumors (P > 0.05).

The HBoV1 can be detected in a relatively high proportion of Iranian patients with gastric cancer (18%) with no predilection for specific subtypes and no association with the degree of lymphocytic infiltration. HBoV1 can also be observed in approximately 20% of chronic gastritis cases. Further comprehensive studies are needed to elucidate the role of HBoV1 in gastric cancer development.

Ulcerative colitis (UC) is a relapsing gastrointestinal disease. Identifying patients at a high risk of UC relapse and initiating preventive treatment can reduce the risk of UC recurrence and its dangerous side effects. The present study was performed to design and pilot test an online calculation tool for relapse risk prediction in UC.

This study is based on our previous prospective study on 157 patients with UC in-remission UC. We designed an online website rooted in our pre-developed equation to calculate relapse risk scores. Then, 280 patients with UC who were not in relapse were randomly selected from our database, and the required information was filled in on the website accordingly. Finally, the indicators were manually calculated using the formula and compared with online-calculated data.

The developed bilingual website is available at http://www.ucrelapserisk.com. Of the 280 patients with UC, 151 (53.9%) were male. 88 patients were at high risk of relapse in the following year. There were no differences between the manually and online calculated Seo index, UC risk score, and probability of relapse in one year.

This online tool is now available for patients and clinicians and provides an accurate relapse risk prediction for UC patients.

In the current era of monitoring healthcare costs for patients with inflammatory bowel disease (IBD), there has been a shift in the pattern of such costs. In this cross-sectional study conducted in three hospitals in Iran from 2015 to 2021, we aimed to assess the in-hospital costs of IBD and identify predictors of higher total hospital costs in hospitalized patients with IBD.

This cross-sectional study was conducted at three hospitals in Iran. For the purpose of this study, we collected demographic and clinical information, as well as cost data for patients with IBD. Two non-parametric statistical procedures, classification and regression trees (CARTs) and quantile regression forests (QRFs), were employed to identify the main factors related to hospital costs of IBD, which served as the dependent variable in our analysis.

During 7 years, 930 admissions occurred in these three hospitals. 22.3% of patients (138 of 619) were readmitted, and 306 (49.4%) were male. The mean age of the patients was 33 (SD = 18.9) years. A total of 454 patients (73.3%) had ulcerative colitis (UC), and 165 patients (26.7%) had Crohn’s disease (CD). Hotelling and medication costs accounted for the largest share of the total hospital costs, with percentages of 30.61% and 23.40%, respectively. Length of stay (LOS) was found to be the most important variable related to hospital costs of IBD in both QRF and CART models, followed by age and year of hospital admission in QRF. Additionally, in the CART model, hospital type and year of hospital admission were also significant predictors of hospital costs for patients with IBD.

The present study showed that LOS, age, year of admission, and the hospital where the patient is admitted are all important factors that determine hospital costs for patients with IBD. Patients admitted for 20.5 days or longer had the highest hospital costs. These findings can be used as thresholds for future DRG policies.

Serum alkaline phosphatase (ALP) is an indicator of hepatobiliary disorders, such as metabolic syndrome (MetS). To assess the association between serum ALP levels and MetS, with or without non-alcoholic fatty liver disease (NAFLD), in a cohort study in northern Iran.

Data from approximately 5257 subjects aged more than 18 years participating in the Amol cohort were used. We extracted the required data and investigated the correlation between liver enzyme levels and MetS. Multiple logistic regression analyses based on the serum ALP quartiles were performed.

Of them, 2860 were male with a mean age of 42.11 ± 16.1 years. A positive linear trend was observed between serum ALP levels and the number of MetS components in both sexes. In both sexes, systolic blood pressure, waist circumferences, and high-density lipoprotein (HDL) had a significant association with ALP. After adjusting for age, both sexes with NAFLD showed an increased risk of developing MetS. The risk of NAFLD increased in individuals with > 2nd quartile of ALP. Furthermore, higher ALP levels were associated with an increased risk of MetS in males (1.1014 [0.782–1.315]) and females (1.441 [1.085–1.913]).

There is a significant association between serum ALP levels and MetS, independent of fatty liver changes, suggesting that this marker can be considered as a feasible predictor of MetS.

Lower gut bleeding is an alarming sign among caregivers. Determining the etiology is of utmost importance for further management. This is the first study conducted in northernmost India.

This cross-sectional study was conducted at the Department of Pediatrics, Government Medical College, Srinagar. This study aimed to describe the etiology of lower gastrointestinal bleeding in the age group of 1-18 years over the past 5 years from June 2017 to June 2022.

A total of 310 children presented with hematochezia (53.5%), blood mixed with loose stools for > 2 weeks (39.3%), melena (1.9%), and occult blood in stools (0.3%). The mean age was 5.12 years. The age group of 1-6 years was 73.5 %. The most common findings were rectosigmoid polyps n = 104 (33.5%), anal fissure n = 47 (15.1%), lymphoid nodular hyperplasia (LNH) n = 38 (12.2%), trichuris dysentery syndrome n = 30(9.7%), cow’s milk protein allergy n = 27(8.7%), non-specific colitis n = 18(5.8%), solitary rectal ulcer syndrome n = 14(4.5%), inflammatory bowel disease n = 6 (1.9%),intestinal tuberculosis n = 3(0.9%), duodenal dieulafoy lesion 1(0.3%), and blue bleb nevus rubber syndrome n = 1(0.3%). 21 patients had a normal colonoscopy. The colonoscopy yield was 93.3 %. Among the colonoscopy-negative patients, 6(1.6%) had Meckel’s diverticulum, and 1(0.3%) had a duodenal dieulafoy lesion.

Lower GI bleeding most commonly presents as hematochezia, and the most common cause is a rectosigmoid polyp. Colonoscopy is the procedure of choice to evaluate the etiology of lower GI bleeding. Anal fissures, LNH, Trichuris trichiura, and cow’s milk protein allergy are other common causes of lower gut bleeding in Kashmir, northernmost India.

Metabolic syndrome (MetS) is a set of conditions that occur together and increase the risk of cardiovascular disease. Previous studies have linked a gluten-free diet (GFD) to obesity and MetS in some populations. However, others have suggested that weight gain is usually regulated only in underweight individuals with celiac disease (CD). Owing to the lack of sufficient data and the importance of GFD in controlling cardiovascular disease, we surveyed the prevalence of MetS and its components before and after a year of GFD in patients referred to the main celiac clinic in southern Iran.

This was a repeated cross-sectional study conducted on 69 patients with a definite diagnosis of cardiovascular disease who were on follow-up and registered at the Shiraz Celiac Clinic. Demographic, anthropometric, and laboratory measurements at the time of diagnosis and one year after the GFD were extracted from their medical records.

The participants’ mean age was 35.53, and 68.1% were women. The prevalence of MetS increased from 5.8% to 11.6% after a year of the GFD; however, this increase was not statistically significant. Waist circumference (WC) and serum triglyceride levels were significantly elevated during the study period.

A GFD may contribute to the development of MetS in patients with cardiovascular disease; however, the rate of MetS is still lower than that in the general population. It is critical to educate patients about these potential risks and encourage them to have a healthy lifestyle that includes a balanced diet and physical activity.

In recent years, we have witnessed an evolving landscape in the management of chronic pancreatitis (CP). Endoscopy plays a pivotal role in CP management. Because the management of CP is problematic, we aimed to review and evaluate the role of endoscopy in the management of CP.

This study was carried out in patients with painful chronic calcific pancreatitis who were admitted to the Department of Gastroenterology at the Sher-I-Kashmir Institute of Medical Sciences (SKIMS), Srinagar. This was an observational prospective study. We included 67 patients with painful chronic calcific pancreatitis and pancreatic duct abnormalities (stones, strictures, or ductal variations) in our study. These patients had to access exocrine and endocrine status before any therapeutic measures. All the patients underwent endoscopic retrograde cholangiopancreatography (ERCP) as a therapeutic measure. After ERCP, the patients were followed up for 2 years to assess improvement in pain (visual analog scale score reduction), endocrine status (HBA1C reduction), or exocrine status (Fecal elastase reduction).

67 patients were included in the study. Among them males were 32 (47.8%), females were 35(52.5%) and the age distribution studied were as in the age group of 15-30 years, patients were 23 (34.3%), in 30-45 years, there was 20 (29.9%), in age group of 45-60 year, patients were 20 (29.9%), and in the age group of 60-75 years, the patients were 4 (6%). Etiology was sought in all patients; alcohol-related CP was seen in three patients (4.5%), genetic in 11 (16.4%), IgG4 in one (1.5%), pancreatic divisum in 6 (9.0%), hyperparathyroidism in on1e (1.5%), and idiopathic in 45 (67.2%). All patients underwent ERCP for their symptoms to reduce ductal pressure, which is postulated as one of the hypotheses for pain in CP. Pancreatic duct (PD) clearance was attempted in all patients (complete in 42 [62.7%], partial in 17 [25.4%], and failed in 8 [11.9%]). These patients were followed for a period of two years after endotherapy, and the important predictors for pain reduction were single PD stones, disease in the head and body, and non-stricturing disease.

Endotherapy offers a high rate of success in selected patients, clearance being better in distal disease and CP without PD strictures, suggesting early disease usually gets cleared very easily.

Hepatitis A virus (HAV) can have severe manifestations in adult patients with other liver diseases, particularly in those infected with human immunodeficiency virus (HIV). This study aimed to measure immunity against HAV in HIV-positive individuals to determine the necessity of vaccination against HAV in this population.

This cross-sectional study investigated 171 HIV-positive patients aged 18 years or older who were tested for serum IgG anti-viral hepatitis A antibody. The prevalence and its determinants were analyzed based on patient data.

The average age of the patients was 44.2 years old. The prevalence of HAV antibody positivity was 97.7%. The prevalence was higher in patients older than 30 years. There was a close association between hepatitis C virus (HCV) infection (P = 0.002). There were no significant correlations between antibody levels and sex, marital status, employment status, education level, economic status, smoking status, drug use status, and physical activity level. The mean and median CD4 + counts in patients with positive (reactive) antibody (Ab) levels were 458 and 404 ± 294, respectively, while the mean and median CD4 + counts in patients with non-reactive antibody levels were 806 and 737 ± 137, respectively, in those who tested negative for anti-HAV Ab (P = 0.05).

The prevalence of anti-hepatitis A IgG antibodies in people with HIV was very high in Shiraz. There is an increasing trend in the number of older patients and those with HCV infections. The negative association with CD4 was borderline in this study, which needs to be confirmed in larger groups.

Hepatocellular carcinoma (HCC) is a major cause of morbidity and mortality in patients with chronic liver diseases (CLDs). Studies have shown a correlation between low serum albumin levels and the aggressiveness of liver cancer. We aimed to determine the prevalence of hypoalbuminemia and its relationship with HCC aggressiveness in our patients.

This study was conducted retrospectively, and data were gathered from the gastroenterology unit of the Department of Medicine at the Aga Khan University Hospital in Karachi, Pakistan. The study included all patients who had been diagnosed with HCC between February 2015 and February 2019.

In total, 380 patients with HCC were included in this study. The mean serum albumin level was 2.79 g/dL (SD ± 0.655) and 318 (83.7%) had serum albumin levels of ≤ 3.5 g/dL. No statistically significant association was identified between albumin levels and parameters of tumor aggressiveness (tumor size, number of tumor nodules, portal vein thrombosis [PVT], and alpha-fetoprotein [AFP] levels) in our patients.

We found no association between low albumin levels and parameters of HCC progression in our patients. This highlights the need for additional markers to determine the severity of HCC in underdeveloped populations.

This case is about a complication of abdominal tuberculosis in the form of a massive lower gastrointestinal (GI) bleed, which was timely intervened by angioembolization. A young man in his mid-20s on empirical anti-tubercular therapy (ATT) for abdominal tuberculosis, presented with severe abdominal pain. The patient then developed frank per rectal bleeding, leading to a significant drop in hemoglobin level, requiring multiple blood transfusions. Upper GI endoscopy and colonoscopy findings were inconclusive. Contrast-enhanced computed tomography (CECT) of the abdomen was performed, which revealed a contrast extravasation into the jejunum due to a leak in the jejunal branch of the superior mesenteric artery (SMA), followed by selective SMA angiography (digital subtraction angiography), which was arrested by angioembolization. The patient had multiple abdominal lymphadenopathies with omental nodules. Histopathological examination of the omental nodules revealed epithelioid granuloma with Langerhans-type cells. The patient is currently receiving ATT and is doing well.

Hepatic epithelioid hemangioendothelioma (EHE) is an uncommon vascular endothelial cell tumor of the liver with numerous symptoms and features. The median affected age is 41, and females are more frequently affected than men. In the following article, a 37-year-old nurse is presented who was referred to the hospital with severe right upper quadrant pain. She had been misdiagnosed with hepatic hemangioma for years, which finally turned out to be hepatic EHE. Liver transplantation has been recognized as the therapeutic method of choice due to the considerable extent of liver involvement and nonresponse to medications.
