Role of endoscopic ultrasound in the characterization of solid pseudopapillary neoplasm of the pancreas

BACKGROUND

Solid pseudopapillary neoplasm (SPN) is an uncommon pathology of the pancreas with unpredictable malignant potential. Endoscopic ultrasound (EUS) assessment plays a vital role in lesion characterization and confirmation of the tissue diagnosis. However, there is a paucity of data regarding the imaging assessment of these lesions.

AIM

To determine the characteristic EUS features of SPN and define its role in preoperative assessment.

METHODS

This was an international, multicenter, retrospective, observational study of prospective cohorts from 7 large hepatopancreaticobiliary centers. All cases with postoperative histology of SPN were included in the study. Data collected included clinical, biochemical, histological and EUS characteristics.

RESULTS

One hundred and six patients with the diagnosis of SPN were included. The mean age was 26 years (range 9 to 70 years), with female predominance (89.6%). The most frequent clinical presentation was abdominal pain (80/106; 75.5%). The mean diameter of the lesion was 53.7 mm (range 15 to 130 mm), with the slight predominant location in the head of the pancreas (44/106; 41.5%). The majority of lesions presented with solid imaging features (59/106; 55.7%) although 33.0% (35/106) had mixed solid/cystic characteristics and 11.3% (12/106) had cystic morphology. Calcification was observed in only 4 (3.8%) cases. Main pancreatic duct dilation was uncommon, evident in only 2 cases (1.9%), whilst common bile duct dilation was observed in 5 (11.3%) cases. One patient demonstrated a double duct sign at presentation. Elastography and Doppler evaluation demonstrated inconsistent appearances with no emergence of a predictable pattern. EUS guided biopsy was performed using three different types of needles: Fine needle aspiration (67/106; 63.2%), fine needle biopsy (37/106; 34.9%), and Sonar Trucut (2/106; 1.9%). The diagnosis was conclusive in 103 (97.2%) cases. Ninety-seven patients were treated surgically (91.5%) and the post-surgical SPN diagnosis was confirmed in all cases. During the 2-year follow-up period, no recurrence was observed.

CONCLUSION

SPN presented primarily as a solid lesion on endosonographic assessment. The lesion tended to be located in the head or body of the pancreas. There was no consistent characteristic pattern apparent on either elastography or Doppler assessment. Similarly SPN did not frequently cause stricture of the pancreatic duct or common bile duct. Importantly, we confirmed that EUS-guided biopsy was an efficient and safe diagnostic tool. The needle type used does not appear to have a significant impact on the diagnostic yield. Overall SPN remains a challenging diagnosis based on EUS imaging with no pathognomonic features. EUS guided biopsy remains the gold standard in establishing the diagnosis.

Metastatic Renal Cell Carcinoma to Pancreas: Case Series and Review of the Literature

Metastasis to the pancreas represents a small proportion of all pancreatic malignancies. Among primary tumors that metastasize to the pancreas, renal cell carcinoma (RCC) is one of the most common causes of metastatic pancreatic lesions. We herein report a case series of three patients with pancreatic metastasis from RCC. The first is a 54-year-old male with a history of left nephrectomy for RCC, in whom an isthmic pancreatic mass suggestive of a neuroendocrine lesion was found during oncological follow-up. Endoscopic ultrasound (EUS)-guided fine needle biopsy (FNB) identified pancreatic metastasis of RCC and the patient was referred for surgery. The second case is a 61-year-old male, hypertensive, diabetic, with left nephrectomy for RCC six years previously, who complained of weight loss and was found with a hyperenhancing mass in the head of the pancreas and a lesion with a similar pattern in the gallbladder. EUS-FNB from the pancreas proved to be a metastatic pancreatic lesion. Cholecystectomy and treatment with tyrosine kinase inhibitors were recommended. The third case is a 68-year-old dialysis patient referred for evaluation of a pancreatic mass, also confirmed by EUS-FNB, who was started on sunitinib treatment. We report a literature summary on epidemiology and clinical features, diagnosis and differential diagnosis and treatment and outcomes in pancreatic metastasis of RCC.

Clinical characteristics and outcomes in carbohydrate antigen 19-9 negative pancreatic cancer

BACKGROUND

Pancreatic ductal adenocarcinoma (PDAC) is a leading cause of death from cancer worldwide. Tumor markers like carbohydrate antigen 19-9 (CA 19-9) have been proven valuable as a diagnostic tool and a predictor for tumor staging and response to therapy.

AIM

To delineate the phenotype of normal CA 19-9 PDAC according to clinical features, disease staging and prognosis as compared with high CA 19-9 PDAC cases.

METHODS

We performed a retrospective single-center analysis of all PDAC cases admitted in our Gastroenterology department over a period of 30 mo that were diagnosed by endoscopic ultrasound-guided tissue acquisition. Patients were divided into two groups according to CA 19-9 levels over a threshold of 37 U/mL. We performed a comparison between the two groups with regard to demographic and clinical data, biomarkers, tumor staging and 6-mo survival.

RESULTS

Altogether 111 patients were recruited with 29 having documented normal CA 19-9 (< 37 U/mL). In the CA 19-9 negative group of patients, 20.68% had elevated levels of both CEA and CA 125, 13.79% for CA 125 only whilst 17.24% for CEA only. The two groups had similar demographic characteristics. Abdominal pain was more frequently reported in positive vs negative CA 19-9 PDAC cases (76.83% vs 55.17%), while smoking was slightly more prevalent in the latter group (28.04% vs 31.03%). Tumors over 2 cm were more frequently seen in the positive CA 19-9 group, reflecting a higher proportion of locally advanced and metastatic neoplasia (87.7% vs 79.3%). Six-month survival was higher for the negative CA 19-9 group (58.62% vs 47.56%).

CONCLUSION

Elevated CA 19-9 at diagnosis seems to be associated with a more pronounced symptomatology, high tumor burden and poor prognosis compared to negative CA 19-9 PDAC cases. CEA and CA 125 can be adjunctive useful markers for PDAC, especially in CA 19-9 negative cases.

Pancreatic involvement in celiac disease

Celiac disease (CD) is well recognized as a systemic, chronic autoimmune disease mainly characterized by gluten-sensitive enteropathy in genetically predisposed individuals but with various extraintestinal features. One of the affected organs in CD is the pancreas, consisting of both endocrine and exocrine alterations. Over the last decades there has been increasing interest in the pancreatic changes in CD, and this has been reflected by a great number of publications looking at this extraintestinal involvement during the course of CD. While pancreatic endocrine changes in CD, focusing on type 1 diabetes mellitus, are well documented in the literature, the relationship with the exocrine pancreas has been less studied. This review summarizes currently available evidence with regard to pancreatic exocrine alterations in CD, focusing on risk of pancreatitis in CD patients, association with autoimmune pancreatitis, prevalence and outcomes of pancreatic exocrine insufficiency in newly diagnosed and gluten-free diet treated CD patients, and the link with cystic fibrosis. In addition, we discuss mechanisms behind the associated pancreatic exocrine impairment in CD and highlight the recommendations for clinical practice.

The Impact of Pancreatic Exocrine Diseases on the β-Cell and Glucose Metabolism-A Review with Currently Available Evidence

Pancreatic exocrine and endocrine dysfunctions often come together in the course of pancreatic diseases as interdependent manifestations of the same organ. However, the mechanisms underlying the bidirectional connection of the exocrine and endocrine pancreas are not fully understood. In this review, we aimed to synthetize the current knowledge regarding the effects of several exocrine pancreatic pathologies on the homeostasis of β-cells, with a special interest in the predisposition toward diabetes mellitus (DM). We focused on the following pancreatic exocrine diseases: chronic pancreatitis, acute pancreatitis, cystic fibrosis, pancreatic cancer, pancreatic resections, and autoimmune pancreatitis. We discuss the pathophysiologic mechanisms behind the impact on β-cell function and evolution into DM, as well as the associated risk factors in progression to DM, and we describe the most relevant and statistically significant findings in the literature. An early and correct diagnosis of DM in the setting of pancreatic exocrine disorders is of paramount importance for anticipating the disease's course and its therapeutical needs.

Physicians' Experience with COVID-19 Vaccination: A Survey Study

BACKGROUND

COVID-19 vaccine hesitancy remains high in the general population and is the main determinant of low vaccination rates and of the fourth pandemic wave severity in Romania. Additional information is needed to raise awareness over vaccine efficiency and the safety profile.

OBJECTIVE

To assess self-reported experience related to COVID-19 vaccination in Romanian physicians.

DESIGN, SETTING, AND PARTICIPANTS

A cross-sectional, self-administered questionnaire-based survey, distributed online in the period 24 March to 24 May 2021. The survey included 30 cascade questions with skip logic filters. All physicians included filled in the questionnaire voluntarily and anonymously. Not all respondents filled in all questions. Main outcome and measure: Primary outcomes addressed were related to the COVID-19 vaccine safety profile.

RESULTS

407/467 (87.15%) of the respondents' physicians were fully vaccinated, mostly with the Pfizer-BioNTech (Comirnaty)-BNT162b2 vaccine, with the peak of immunization in January 2021, with almost four-fifths of the study participants. Regarding COVID-19, almost 20% physicians had the infection and one declared COVID-19 re-infection. A number of 48/420 (11.42%) and 47/419 (11.22%) of the vaccinated physicians did not report any side effects after the first or second vaccine dose. However, most of the side effects reported were minor. Only 50/360 (13.88%) physicians reported the vaccine side effects on the dedicated online national platform. Approximately 40% respondents checked the anti-spike SARS-CoV2 antibodies' titer after complete vaccination, of which two cases reported indeterminate levels. Lower anti-spike SARS-CoV2 antibodies' titer of 100-1000 times the laboratory limit was more frequent in naive physicians (36.95% versus 14.28%, p = 0.012), moderate titers were similar, while very high levels, more than 10,000 times laboratory limit, were more frequent in physicians with previous COVID-19 infection (2.17% versus 42.85%, p < 0.001).

CONCLUSIONS AND RELEVANCE

In this cross-sectional survey study on the COVID-19 vaccination among Romanian physicians, we describe a safety vaccination profile among Romanian physicians.

Diagnostic Application of Volatile Organic Compounds as Potential Biomarkers for Detecting Digestive Neoplasia: A Systematic Review

Volatile organic compounds (VOCs) are part of the exhaled breath that were proposed as non-invasive breath biomarkers via different human discharge products like saliva, breath, urine, blood, or tissues. Particularly, due to the non-invasive approach, VOCs were considered as potential biomarkers for non-invasive early cancer detection. We herein aimed to review the data over VOCs utility in digestive neoplasia as early diagnosis or monitoring biomarkers. A systematic literature search was done using MEDLINE via PubMed, Cochrane Library, and Thomson Reuters' Web of Science Core Collection. We identified sixteen articles that were included in the final analysis. Based on the current knowledge, we cannot identify a single VOC as a specific non-invasive biomarker for digestive neoplasia. Several combinations of up to twelve VOCs seem promising for accurately detecting some neoplasia types. A combination of different VOCs breath expression are promising tools for digestive neoplasia screening.

Abdominal imaging in COVID-19

Initially thought of as a respiratory infection, coronavirus disease-2019 (COVID-19) is now recognized as a complex disease with a wide clinical spectrum, including digestive involvement. While several studies have evaluated chest imaging findings in COVID-19, few papers have looked at the abdominal imaging features of these patients. Liver, biliary, pancreas and bowel involvement have been reported in COVID-19 infected patients. In this review, we aim to summarize currently available data related to abdominal imaging techniques in COVID-19, in accordance with relevant clinical and laboratory workup of these patients. Underlying mechanisms, indications and imaging findings related to COVID-19 are discussed based on published data. Also, practice points for clinicians are highlighted in order to adequately recognize digestive-related injuries of severe acute respiratory syndrome coronavirus 2 infection. While there’s been a steady accumulation of data with respect to abdominal imaging findings in COVID-19, currently available recommendations are based on limited research. There is a wide spectrum of abdominal imaging findings in COVID-19, which includes hepato-biliary, pancreatic and luminal pathology.

Perceptions of Romanian Physicians on Lockdowns for COVID-19 Prevention

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease (COVID-19) was declared a pandemic in March 2020, triggering important changes for the entire society and healthcare systems, as well as significant lockdown measures aimed to limit the disease spread. We herein intended to catch the dynamic of Romanian physicians' perceptions of COVID-19 impact. For this purpose, after a literature review, a 30-item questionnaire was designed. The questionnaire was twice distributed online, about 1 month apart, during which partial relaxation measures were decreed in Romania. The questionnaire was voluntarily filled in by Romanian physicians who were willing to participate in the study. A total of 214 physicians answered the questionnaire upon its first release, and 199 respondents were registered upon its second release, most of whom (94.9%) were involved in clinical work, with one-third working in units dedicated to COVID-19 patients. In parallel with the relaxation of lockdown measures, along with increased confidence in the efficiency of protective measures (46.7% vs. 31.3%), separation from household members decreased from 36.9% to 22.1%. Nevertheless, the feeling of rejection felt by doctors remained similar (22.4% vs. 24.6%). Furthermore, answers regarding the clinical picture, diagnostic approach, and treatment options are discussed. Most of therapeutic options considered for SARS-CoV-2 treatment (e.g., lopinavir/ritonavir, oseltamivir, hydroxychloroquine, azithromycin, tocilizumab, and convalescent plasma) failed to confirm significant efficiency. On the contrary, vaccines for widescale use are already available despite the initial skepticism. In the beginning of the pandemic, 25.2% (18.2% vs. 32.2%) considered that there will not be an effective COVID-19 vaccine, while 41.6% (43.0% vs. 40.2%) thought that a vaccine would be available after at least 12 months. In conclusion, initially, following only a 1 month period, Romanian physicians' intention to consider treatments such as hydroxychloroquine or lopinavir/ritonavir for COVID-19 decreased significantly. Moreover, confidence in the efficiency of available protective measures increased, and the rates of separation from household members decreased.

Systemic lupus erythematosus-related acute pancreatitis

INTRODUCTION

Systemic lupus erythematosus (SLE) is a complex autoimmune pathology that can involve any organ. Lupus-related acute pancreatitis (AP) is, together with lupus mesenteric vasculitis, an important cause of SLE-induced acute abdominal pain.

METHODS

A literature search was conducted using the terms "Pancreatitis" and "Lupus Erythematosus, Systemic" on PubMed/Medline and Web of Science from January 2007 to January 2020. Clinical characteristics, diagnostic approach, and treatment principles in SLE-related AP are presented in this review.

RESULTS

Mainly retrospective reports were identified. The reported incidence of SLE-associated AP ranges from 0.9 to more than 5% of patients. A total of 264 SLE patients were found in the selected research, with a net female predominance (sex ratio 9:1) and mean age of 31.4 years. Abdominal pain was virtually present in all cases. AP occurrence was more frequent in SLE patients with short disease duration, high activity scores, and multiorgan involvement. The AP definition was based on currently available guidelines and after exclusion of any other known causes (including iatrogenic, i.e. drugs), a diagnosis of "idiopathic" SLE-related AP might be sustained. Management is difficult, as there is no standardized therapeutic approach. Of note, glucocorticoid use remains still controversial as, especially for high doses, subsequent pancreatic injury may occur. Monitoring serum lipase levels after high dose steroids might be considered. One study reported beneficial prognostic effect of plasma exchange. Moreover, AP in SLE might raise awareness about macrophage activation syndrome association. Mortality up to one third of AP cases in SLE was reported.

CONCLUSION

The SLE-related AP is a rare, but severe, life-threatening complication. Corticosteroids must be used with caution. Plasma exchange could be considered in selected cases.

Cutaneous Manifestations in Pancreatic Diseases-A Review

Pancreatic pathology, comprising acute and chronic pancreatitis, autoimmune pancreatitis and pancreatic neoplasms, primarily presents with gastrointestinal symptoms and signs; however, it is well recognized that it can also associate a wide range of extra-digestive features. Among these systemic manifestations, cutaneous involvement plays an important role both as a diagnostic clue for the pancreatic disease itself and serving as a prognostic factor for the severity of the condition. Recognition of these cutaneous signs is, however, far from being satisfactory, all the more as some of them are relatively rare. In the current review, we discuss skin involvement in pancreatic diseases, referring to pancreatic panniculitis, cutaneous hemorrhagic manifestations, skin metastasis, acanthosis nigricans, livedo reticularis, necrolytic migratory erythema and cutaneous fistula. We highlight the clinical characteristics, treatment and prognostic value of these lesions. Better awareness among medical specialties other than dermatology is needed for detection of the skin clues associated with pancreatic pathology.

Physicians' Perspectives on COVID-19: An International Survey

Coronavirus disease 2019 (COVID-19) has put a tremendous pressure over health care systems worldwide. Physicians were faced to fight this novel, emerging disease, without evidence-based recommendations. Our aim was to investigate physicians' point of view regarding the new coronavirus disease. We designed an on-line survey with 30 questions to assess physicians' perception of personal impact as well as epidemiology, clinical features, management, and outcome in COVID-19. A total of 194 physicians from 43 countries, of which 42.3% were male, 45.4% had more than 5 years' experience and 10.8% were heads of department/professors, filled-out the questionnaire. Although 47.4% of the physicians were currently treating patients, over 80% thought that they might get in contact with COVID-19 patients. A total of 36.6% physicians thought that they are not and 30.9% were not sure if they were being protected by the ongoing procedures. A total of 21.1% of the doctors felt that they are avoided by the persons with whom they usually interact in daily life and 24.7% were isolated from the household members they usually live with. A total of 72.7% of physicians considered that COVID-19-free patients are currently neglected. The results of the current survey raise awareness about the impact of COVID-19 on physicians' practice.

Digital histology in celiac disease: A practice changer

Artificial intelligence (AI) has grown tremendously in the last decades and is undoubtedly the future era in medicine. Concerning digestive diseases, applications of AI include clinical gastroenterology, gastrointestinal endoscopy and imaging, and not least pathological diagnosis. Several gastrointestinal pathologies require histological confirmation for a positive diagnosis. Among them, celiac disease (CD) diagnosis has been in the spotlight over time, but controversy is still ongoing with regard to the so-called celiac-type histology. Despite efforts to improve histological diagnosis in CD, there are still several issues and pitfalls associated with duodenal histology reading. Several papers have assessed the accuracy of AI techniques in detecting CD on duodenal biopsy images and have shown high diagnostic performance over standard histology reading. We discuss the role of computer-assisted histology in improving the assessment of mucosal architectural injury and inflammation in CD patients, both for diagnosis and follow-up.

Current Evidence on Computer-Aided Diagnosis of Celiac Disease: Systematic Review

Celiac disease (CD) is a chronic autoimmune disease that occurs in genetically predisposed individuals in whom the ingestion of gluten leads to damage of the small bowel. It is estimated to affect 1 in 100 people worldwide, but is severely underdiagnosed. Currently available guidelines require CD-specific serology and atrophic histology in duodenal biopsy samples for the diagnosis of adult CD. In pediatric CD, but in recent years in adults also, nonbioptic diagnostic strategies have become increasingly popular. In this setting, in order to increase the diagnostic rate of this pathology, endoscopy itself has been thought of as a case finding strategy by use of digital image processing techniques. Research focused on computer aided decision support used as database video capsule, endoscopy and even biopsy duodenal images. Early automated methods for diagnosis of celiac disease used feature extraction methods like spatial domain features, transform domain features, scale-invariant features and spatio-temporal features. Recent artificial intelligence (AI) techniques using deep learning (DL) methods such as convolutional neural network (CNN), support vector machines (SVM) or Bayesian inference have emerged as a breakthrough computer technology which can be used for computer aided diagnosis of celiac disease. In the current review we summarize methods used in clinical studies for classification of CD from feature extraction methods to AI techniques.

Non-alcoholic fatty pancreas disease - practices for clinicians

Obesity is a growing health burden worldwide, increasing the risk for several diseases featuring the metabolic syndrome - type 2 diabetes mellitus, dyslipidemia, non-alcoholic fatty liver disease and cardiovascular diseases. With the increasing epidemic of obesity, a new pathologic condition has emerged as a component of the metabolic syndrome - that of non-alcoholic fatty pancreas disease (NAFPD). Similar to non-alcoholic fatty liver disease (NAFLD), NAFPD comprises a wide spectrum of disease - from deposition of fat in the pancreas - fatty pancreas, to pancreatic inflammation and possibly pancreatic fibrosis. In contrast with NAFLD, diagnostic evaluation of NAFPD is less standardized, consisting mostly in imaging methods. Also the natural evolution of NAFPD and its association with pancreatic cancer is much less studied. Not least, the clinical consequences of NAFPD remain largely presumptions and knowledge about its metabolic impact is limited. This review will cover epidemiology, pathogenesis, diagnostic evaluation tools and treatment options for NAFPD, with focus on practices for clinicians.

Hematologic Manifestations in Celiac Disease-A Practical Review

Celiac disease (CD) is a systemic autoimmune disease driven by gluten-ingestion in genetically predisposed individuals. Although it primarily affects the small bowel, CD can also involve other organs and manifest as an extraintestinal disease. Among the extraintestinal features of CD, hematologic ones are rather frequent and consist of anemia, thrombocytosis (thrombocytopenia also, but rare), thrombotic or hemorrhagic events, IgA deficiency, hyposplenism, and lymphoma. These hematologic alterations can be the sole manifestation of the disease and should prompt for CD testing in a suggestive clinical scenario. Recognition of these atypical, extraintestinal presentations, including hematologic ones, could represent a great opportunity to increase the diagnostic rate of CD, which is currently one of the most underdiagnosed chronic digestive disorders worldwide. In this review, we summarize recent evidence regarding the hematological manifestations of CD, with focus on practical recommendations for clinicians.

Hemorrhagic Events in Adult Celiac Disease Patients. Case Report and Review of the Literature

BACKGROUND AND AIMS

Celiac disease (CD) presents with a wide spectrum of extra-digestive symptoms, including hemorrhagic manifestations. The aim of this review was to conduct an extensive analysis of the hemorrhagic events reported in adult CD patients.

METHODS

Case report and review of the literature. Pubmed (MEDLINE) database search from January 1970 onwards was performed using the medical subject headings [MeSH] terms "celiac disease" AND "blood coagulation disorders", "hemorrhage", "hematoma", "hematuria", "hemoptysis", "epistaxis", "hemosiderosis". Only case reports were identified on the search theme. Information on patients' characteristics, diagnostic features, coagulation parameters, symptomatology duration, and evolution under treatment were systematically collected and summarized.

RESULTS

We present the case of a 40-year-old man hospitalized for spontaneous muscular hematomas, in whom CD was diagnosed. We performed a review of the literature and summarized the published case reports of 46 CD patients, aged between 19 and 74 years, 64% of male gender. In 25% of cases, the symptomatology was present for more than 5 years prior to CD diagnosis. The clinical hemorrhagic events were as follows: 15 patients had gastrointestinal bleeding, 9 hemoptysis, 4 epistaxis, 6 hematuria, 8 cutaneous hematoma, petechia or ecchymoses, and only in 1 case hemarthrosis, hemorrhagic vesicular dermatitis, subcortical hemorrhage, or adrenal hemorrhage. Sixty percent of the patients had digestive symptoms, while the rest had only extra-digestive CD involvement. The Lane Hamilton syndrome was defined in 15 patients. The evolution under a gluten-free diet was favorable in most cases.

CONCLUSION

This review of case reports aims to increase awareness to hemorrhagic events, rare but possible life-threatening conditions, as part of the CD clinical spectrum. To the best of our knowledge, this is the first review of all types of hemorrhagic events in adult CD patients.

Ratio of spleen diameter to red blood cell distribution width: a novel indicator for celiac disease

Celiac disease (CD) is currently considerably underdiagnosed, setting the need for developing tools to select patients with probability of CD, who warrant further testing. Red blood cell distribution width (RDW) has been shown in previous studies to be a sensitive predictor for CD, but it lacks specificity. Splenic hypotrophy is also noted frequently in celiac patients. Our aim was to evaluate if spleen diameter to RDW ratio can be used as an indicator for CD. We evaluated 15 newly diagnosed CD patients, 52 patients with inflammatory bowel disease, and 35 patients with irritable bowel syndrome (IBS). We evaluated the differences in spleen diameter, RDW, and their ratio among the four groups. Two-thirds of the CD patients had elevated RDW, compared to 9% in the IBS group. A small spleen was seen in 80% of the celiacs, compared to 21.9% in the ulcerative colitis group, 10% in the Crohn disease group, and 9% in the IBS group. A spleen diameter to RDW ratio under 6 had a sensitivity of 73.3% and specificity of 88.5% in predicting CD, with an AUROC of 0.737. Spleen diameter to RDW ratio is a simple, widely available score, which can be used to select adult patients with probability of CD.
