The effect of hepatic steatosis on COVID-19 severity: Chest computed tomography findings
Selçuk Parlak, Esra Çıvgın, Muhammed Said Beşler, Afşin Emre Kayıpmaz
March-April 2021, 27(2):105-110
DOI

PMID
:33642355
Background:
The objective of our study was to investigate the location, extension and type of novel coronavirus-induced disease 2019 (COVID-19) infection involvement and hepatic steatosis on initial chest computed tomography (CT). The relationship between fatty liver and severity of the disease was also investigated by measuring the liver attenuation index (LAI).
Methods:
This study evaluated the chest CT images of 343 patients (201 male, mean age 48.43 years) who were confirmed to have COVID-19, using nasopharyngeal swab. The chest CTs were analyzed for laterality, number of involved lobes, diffuseness, number of lesions, and lesion types. The CT attenuation values of liver and spleen were measured, and LAI was calculated for the detection of hepatic steatosis. Univariate and multivariate logistic regression analysis were used to identify the independent early predictors for severe COVID-19.
Results:
There was no significant difference between genders in terms of clinical course. Liver density and LAI were significantly lower in the intensive care unit (ICU) patients. The prevalence of severe disease was higher in the patients with hepatic steatosis than in the non-steatotic group (odds ratio [OR] 3.815, 95% confidence interval [CI] 1.97–7.37,
P
< 0.001). After adjusting for age and comorbidities including hypertension, diabetes mellitus, coronary artery disease, chronic obstructive pulmonary disease, and chronic kidney disease, multivariate logistic regression analysis showed that non-alcoholic fatty liver disease (NAFLD) was an independent risk factor for COVID-19 severity (OR 3.935, 95% CI 1.77-8.70,
P
= 0.001). The optimal cut-off value for LAI was calculated as 0.5 for predicting patients who required ICU treatment.
Conclusions:
On the initial chest CT images of COVID-19 patients, presence of fatty liver is a strong predictor for severe disease.

Mais AlSardi, Dimah AlAskar, Majid Alsahafi, Turki AlAmeel, Eman Al Sulais
March-April 2021, 27(2):73-78
DOI

PMID

Background:
Clinical research is essential for the advancement of medical knowledge and evidence-based medical practice. In this study, we aimed to identify barriers that limit research productivity among gastroenterologists in Saudi Arabia.
Methods:
We conducted a national online survey targeting gastroenterologists in Saudi Arabia. Participants were asked about the patterns of their practice, their prior research activities, and potential barriers to research productivity. Univariate and multivariate analyses were performed to examine the association between different factors and research productivity.
Results:
A total of 85 gastroenterologists completed the survey. Respondents were predominantly male physicians (90.6%) and 40% of them belonged to the age group of 40-49 years. About 85.9% had at least one prior research participation of any type. Around 67.1% of the respondents had been a primary investigator at least once in the last 5 years, while only 23.5% had been a primary investigator at a minimum average rate of once a year. Multiple barriers to research productivity were identified: insufficient research time (78.8%), lack of funding and compensation (77.6%), lack of a statistician (68.2%), insufficient research training (64.7%), lack of connection (60%), lack of technical support (57.6%), and lack of interest (31%). On univariate analysis, insufficient research time and lack of funding and compensation were significantly associated with no research participation
(P
<0.01 and 0.03, respectively). On multivariate analysis, lack of funding and compensation was independently associated with no research participation (adjusted OR 15.32;95% C.I 2.66, 121.58,
P
< 0.01).
Conclusions:
Barriers to research productivity are highly prevalent among gastroenterologists in Saudi Arabia. Insufficient research time and lack of funding and compensation are the most common. Interventions are needed to promote research activities.

Clinical characteristics, natural history, and outcomes of Crohn's-related intra-abdominal collections
Othman Alharbi, Majid A Almadi, Nahla Azzam, Abdulrahman M Aljebreen, Turki AlAmeel, Stefan Schreiber, Mahmoud H Mosli
March-April 2021, 27(2):79-84
DOI

PMID
:33723092
Background:
Intra-abdominal collections in the form of abscesses or matted bowel loops, called phlegmons, might occur in patients with Crohn's disease (CD). The clinical characteristics and management of such conditions are not well described. We aim to characterize CD-related intra-abdominal collections clinically, and identify predictors of need for surgical interventions and the time to surgery.
Methods:
We utilized the Saudi Inflammatory Bowel Disease Information System (IBDIS) database to identify all patients treated for radiologically proven intra-abdominal abscesses or phlegmons since inception. Demographics, clinical data, clinical course, and treatment outcomes were recorded. Logistic regression analysis and survival analysis were used to identify predictors of surgical resection and differences in time to surgery between patient subgroups, respectively.
Results:
A total of 734 patients with a diagnosis of CD were screened and 75 patients were identified. The mean age was 25.6 ± 9.9 years and 51% were males. Nearly 60% of patients had abscesses larger than 3 cm while 13% had smaller abscesses and 36% had phlegmons. On presentation, the most commonly reported symptom was abdominal pain (99%) followed by weight loss (27%). About 89% of patients were treated with antibiotics during hospitalization for an average of 2.7 weeks. Steroids were prescribed for 52% of patients and tumor necrosis factor alpha (TNF-alpha) antagonists for 17%. Surgical resection was required for 33 patients (44% of the cohort) while 51% were managed with antibiotics and/or percutaneous drainage. The most common surgical intervention was ileocecal resection (45%). Although patients who underwent follow-up imaging were more likely to require early surgical intervention (
P
= 0.04), no statistically significant predictor of surgery could be identified from this cohort. Time to surgery varied numerically according to abscess size (HR = 1.18, 95% CI = 0.62–2.27,
P
= 0.61).
Conclusions:
Although the majority of patients with CD-related intra-abdominal collections underwent surgical resection in this cohort, no obvious predictors of surgical intervention could be identified. The decision to perform early surgery appeared to be influenced by the findings observed on cross-sectional imaging during the follow-up of these collections.

Background:
Peripancreatic fluid collections (PFCs) are a frequent complication of acute pancreatitis. Symptomatic PFCs may need to be drained, and there are multiple endoscopic accessories that can facilitate the procedure. This paper aims to compare the success rate, number of procedures required for resolution and adverse events rate for PFCs EUS-guided drainage with plastic stents and lumen-apposing metal stents (LAMS).
Methods:
This is a retrospective analysis of a consecutive sample of patients that was collected from 2013 – 2019. The medical records of these patients were reviewed, and the outcomes for each type of stent (plastic vs LAMS, and different subtypes of LAMS) were compared in terms of clinical success, number of re-interventions needed, and adverse events.
Results:
A total of 33 patients (23 males) were treated for PFCs with EUS-guided drainage and stenting. The patients' ages ranged between 14 and 85 years (mean ± SD: 43.5 ± 19 years). Overall, there was no difference between plastic stents and LAMS in terms of symptomatic recovery (
P
= 0. 24), but metal stents had better results with regards to radiological resolution (
P
= 0.03), and were associated with a higher number of necrosectomies (
P
= 0.029). Adverse events occurred more frequently in patients who had plastic stents, but direct comparison between the two groups showed that the difference was not statistically significant (
P
= 0.2). Stratification for different LAMS subtypes showed no difference in terms of symptomatic or radiological resolution (
P
=0.49), number of rescue procedures (
P
= 0.41), and adverse events (
P
= 0.81).
Conclusion:
Our study, along with the current available evidence, suggests a slight advantage of metal stents over plastic stents in terms of clinical success, need for rescue procedures, and incidence of adverse events. Furthermore, it provides empirical evidence that the different sub-types of LAMS perform similarly when compared against each other.

The efficacy of the application of the curative criteria of the 5
rd
edition Japanese gastric cancer treatment guidelines for early adenocarcinoma of the esophagogastric junction treated by endoscopic submucosal dissection
Zhihao Chen, Yong Liu, Lizhou Dou, Yueming Zhang, Shun He, Guiqi Wang
March-April 2021, 27(2):97-104
DOI
:10.4103/sjg.SJG_403_20
PMID
:33642353
Background:
The curative criteria after endoscopic submucosal dissection for early gastric carcinoma were updated by the Japanese Gastric Cancer Association. No study has shown promising results with endoscopic submucosal dissection for early adenocarcinoma of esophagogastric junction based on the new curative criteria. The purpose of this study was to validate clinical efficacy of the application of the curative criteria of the 5th edition Japanese gastric cancer treatment guidelines for early adenocarcinoma of esophagogastric junction after endoscopic submucosal dissection.
Methods:
Patients who underwent endoscopic submucosal dissection for Siewert type II adenocarcinoma between January 2013 and June 2018 were eligible for this study. Clinical and pathological features and treatment outcomes were retrospectively reviewed using medical records.
Results:
The success rate for en-bloc resection was 97.2% (172/177) and the curative resection rate was 71.2% (126/177). Additional endoscopic submucosal dissection or radical surgery was conducted in 10 patients (5.6%) who did not fulfil the curative resection criteria, while one patient with curative resection remedied with endoscopic submucosal dissection because of recurrence. According to eCura scoring system, 94 patients (53.1%) were categorized into eCura A, 34 patients (19.2%) into eCura B, 11 patients (6.2%) into eCura C-1, and 38 patients (21.5%) into eCura C-2. Five patients categorized as eCura C-2 underwent radical surgery, two of whom have lymph node metastasis.
Conclusions:
Endoscopic submucosal dissection for early adenocarcinoma of esophagogastric junction that met the expanded criteria of the 5th edition Japanese gastric cancer treatment guidelines were acceptable and should be the standard treatment instead of surgical resection.

PMID
:33723091
Background:
Crohn's disease (CD) is a progressive illness associated with high morbidity owing to the complications associated with the condition. Patients' awareness and cognition of such complications may carry significant psychological impact. The aim of this study is to assess the illness cognition of Saudi patients diagnosed with CD and to identify clinical associations.
Methods:
Adult patients with CD were asked to complete an illness cognition questionnaire (ICQ) between January and December of 2019. Additional data was extracted from the medical records. The ICQ composed of three domains: Helplessness (6 items), acceptance (6 items), and perceived benefits (6 items). Descriptive statistics were used to summarize patient characteristics and a linear regression analysis was used to identify associations with the ICQ score.
Results:
A total of 88 patients were included, of which 55.8% were females, 18% were smokers, and 11.5% had undergone CD-related surgery. The mean age was 26.9 ± 7.7 years and the mean duration of disease was 54.7 ± 60.5 months. The mean score was 17.4 ± 3.6 for the helplessness domain, 13.4 ± 3.6 for the acceptance domain, and 13.5 ± 3.5 for the perceived benefits domain. We found associations between abdominal pain and acceptance (
P
= 0.048), extra intestinal manifestations and perceived benefit (
P
= 0.001), and treatment with mesalamine and helplessness (
P
= 0.03). In a linear regression analysis, albumin level was the only factor associated with helplessness (coef = 0.18,
P
= 0.048).
Conclusions:
A considerable proportion of Saudi patients diagnosed with CD generally reported a negative perception of their disease. Albumin level was associated with helplessness.

Surveillance for hepatocellular carcinoma in patients with advanced liver fibrosis
Angelo Sangiovanni, Massimo Colombo

Surveillance is the only pragmatic approach to improve treatment of hepatocellular carcinoma (HCC) owing to the fact that it allows detection of the tumor at an early and better curable stage. International liver societies recommend surveillance with biannual abdominal ultrasound (US) for patients with cirrhosis of any etiology because of their high risk of developing HCC. This strategy is considered cost-effective, as surveillance requires an articulated and costly set of interventions, including linkage to care of patients with an early detected tumor. However, as transition to HCC is increasingly being observed in noncirrhotic patients, the majority of which does not reach the threshold of cost effectiveness for screening. The European and Japanese liver societies elected to confine recommendations for HCC screening to noncirrhotic patients with advanced fibrosis due to hepatitis C or hepatitis B only. These latter recommendations, however, are challenged by the increasing number of patients with viral hepatitis in whom HCC risk has been attenuated but not eradicated by successful antiviral therapy. In this set of patients, entry criteria of surveillance need to be refined in the light of the suboptimal diagnostic accuracy of non invasive tests that are employed to identify the ideal candidates for surveillance.
