RESUMO

Eosinophilic gastroenteritis poses a significant diagnostic challenge, particularly in developing countries, where the awareness of this condition may be limited. Here, the case of a patient in her early 30s, who presented with recurrent episodes of abdominal pain and diarrhea, is reported. Initial standard laboratory investigations revealed normal complete blood counts and elevated total serum immunoglobulin E levels. Upper and lower endoscopic evaluations with systemic biopsies did not reveal any significant abnormalities. However, computed tomography revealed a thickened small intestine wall, halo signs, and mild ascites. Analysis of the ascitic fluid confirmed eosinophilia. These findings prompted a diagnosis of eosinophilic gastroenteritis. The patient responded well to a targeted elimination diet, corticosteroids, and antileukotriene medication. The present case emphasizes the importance of considering eosinophilic gastroenteritis in the differential diagnosis of patients who present with abdominal pain and eosinophilic ascites.

RESUMO

INTRODUCTION: Spontaneous bacterial peritonitis (SBP) is a potentially life-threatening complication of cirrhotic ascites. Early diagnosis and treatment of SBP are essential to improve the survival rates and prognosis of patients. We aimed to identify the predictors of SBP to establish a new noninvasive early diagnostic tool. METHODS: We screened 1618 patients who underwent paracentesis due to cirrhotic ascites between January 2017 and December 2018 in three hospitals. We evaluated the symptomatic, clinical, and laboratory parameters to identify the predictors of SBP. The primary diagnostic model was displayed as a nomogram. RESULTS: The model included abdominal pain, diarrhea, white blood cell count, neutrophil percentage, procalcitonin, C-reactive protein, lactate dehydrogenase, glucose, and Model for End-stage Liver Disease score. The model's diagnostic performance was good, with an AUC of 0.84 [95% confidence interval (CI), 0.81-0.87] in the training cohort. In the validation cohort, the diagnostic ability was also good, with AUCs of 0.87 (95% CI, 0.83-0.91) and 0.90 (95% CI, 0.87-0.94) for inner and outer validation queues, respectively. Moreover, the decision curve analysis confirmed the clinical utility of the nomogram model. In addition, we developed a Microsoft Excel calculation model to allow convenient adoption of the model in clinical practice. CONCLUSION: We developed good performing diagnostic models for SBP.

RESUMO

Eosinophilic gastroenteritis (EG) is an inflammatory bowel condition characterised by eosinophilic infiltration of the stomach and small bowel. Smoking and certain foods can trigger EG.A man in his 40s presented to the emergency department with acute abdominal pain. He had rebound tenderness and guarding on his initial abdominal examination. A subsequent CT scan showed jejunal wall thickening and ascitesHe had similar attacks of abdominal pain and was misdiagnosed with familial Mediterranean fever and Crohn's disease.Paracentesis revealed eosinophilic ascites. No mucosal abnormality was detected on gastroduodenoscopy and colonoscopy. A double-balloon enteroscopy revealed mucosal inflammation in the jejunum and a biopsy was taken. In this biopsy, eosinophilic jejunitis was detected. He was given corticosteroids and montelukast and his condition was resolved promptly. After discharge, he had attacks of EG until he quit smoking. After quitting smoking, he had an attack once in the last 2 years after consuming eggplant.

RESUMO

Portal vein thrombosis (PVT) is a common thrombotic complication of cirrhosis. It can lead to variceal bleeding and bowel ischemia and also complicate liver transplantation. Identifying the possible risk factors associated with PVT can aid in identifying patients at high risk, enabling their screening and potentially preventing PVT through the rational use of anticoagulants. This study focuses on examining the clinical characteristics of PVT in cirrhotic patients and identifying the clinical and biochemical factors that are linked to the development of PVT. Consecutive hospitalized cirrhotic patients between 2015 and 2023 were identified through the hospital's computerized medical records based on the Tenth Revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) coding system and retrospectively analyzed. 928 individuals were included in this study; 783 (84.3%) without PVT and 145 (15.7%) with benign PVT. Hepatitis B virus (HBV) was significantly more common in the PVT group (P-value = .02), while alcohol and primary sclerosing cholangitis (PSC) were less common in this group (P-value = .01 and .02, respectively). Hepatocellular carcinoma (HCC) (P-value < .01), ascites (P-value = .01), and spontaneous bacterial peritonitis (SBP) (P-value = .02) were more common in the PVT group. Patients with PVT had a higher international normalized ratio (INR) level (P-value = .042) and lower plasma albumin (P-value = .01). No differences were identified in white blood cell, hemoglobin, platelet, and bilirubin levels. However, patients with PVT had higher model for end-stage liver disease (MELD) (P-value = .01) and Child-Pugh scores (P-value = .03). This study demonstrated a higher likelihood of PVT presence in cirrhotic patients with advanced age, HBV, and HCC, along with ascites, SBP, splenomegaly, hypoalbuminemia, elevated INR, and a higher MELD score. Nevertheless, additional research endeavors are necessary to accurately ascertain and validate supplementary risk factors within a broader demographic.

RESUMO

BACKGROUND: Terlipressin has been widely used for various cirrhosis-related complications, but its safety profile remains controversial. Herein, this issue was systematically evaluated. METHODS: All studies reporting adverse events (AEs) of terlipressin in cirrhosis were screened. Incidences were pooled using a random-effects model. Subgroup analyses were performed according to the patient's characteristics and treatment regimens. Interaction among subgroups was evaluated. RESULTS: Seventy-eight studies with 7257 patients with cirrhosis were included. The pooled incidences of any AEs, treatment-related AEs, any serious AEs (SAEs), treatment-related SAEs, treatment withdrawal due to AEs, and treatment withdrawal due to treatment-related AEs were 31%, 22%, 5%, 5%, 4%, and 4% in patients with cirrhosis receiving terlipressin, respectively. Patients with hepatorenal syndrome had higher incidences of any SAEs (29% vs. 0% vs. 0%, pinteraction = 0.01) and treatment-related SAEs (8% vs. 1% vs. 7%, pinteraction = 0.02) than those with variceal bleeding or ascites. Patients who received terlipressin with human albumin had higher incidences of any SAEs (18% vs. 1%, pinteraction = 0.04) and treatment-related SAEs (7% vs. 0%, pinteraction = 0.09) than those without albumin. Patients with total bilirubin level >4.3 mg/dL had higher incidences of any AEs (69% vs. 24%, pinteraction = 0.02), any SAEs (64% vs. 0%, pinteraction < 0.01), and treatment-related SAEs (8% vs. 1%, pinteraction = 0.04) than those ≤4.3 mg/dL. CONCLUSIONS: AEs are common in patients with cirrhosis receiving terlipressin and influenced by clinical scenarios, combination with albumin, and bilirubin levels.

RESUMO

OBJECTIVE: Aim: To evaluate the peculiarities of the course of complications and the provision of care for portal hypertension associated with the development of diureticresistant ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, and variceal bleeding. PATIENTS AND METHODS: Materials and Methods: This research is based on a review of the literature in PubMed, CrossRef, Google Scholar sources on complicated portal hypertension. Such complications of portal hypertension as spontaneous bacterial peritonitis, ascites, hepatorenal sуndrome, variceal bleeding caused by sinistral portal hypertension are considered. The effectiveness of interventional treatment methods and laparoscopic surgical interventions has been demonstrated. CONCLUSION: Conclusions: Diagnosis and treatment of patients with complicated portal hypertension requires a multidisciplinary approach, which is due to the diverse pathophysiological process of portal hypertension. The possibilities of providing emergency care to this category of patients depend on the level of medical training of the staff, the possibilities of medical and technical support in the provision of interventional care, the ineffectiveness of which necessitates surgical treatment using minimally invasive technologies.

RESUMO

Hepatic edema is caused by decreased hepatic protein synthesis, a consequence of decompensated liver cirrhosis. Fluid accumulation occurs when there is an increase in hydrostatic pressure in the hepatic sinusoids and splanchnic capillaries, as well as low albumin. The first-line treatment for cirrhosis-related ascites is an aldosterone antagonist (spironolactone); however, in severe and recurring ascites, a combination of aldosterone antagonists and loop diuretics (torsemide, furosemide, and bumetanide) is preferable. Torsemide outperformed furosemide in terms of natriuretic and diuretic effects at an equivalent dose. Pharmacological features of torsemide, such as lesser hypokalemia effect, longer duration of action, higher bioavailability, and extended half-life, make it a better alternative than furosemide. In clinical studies, it is considered a safer and more acceptable choice with fewer complications.

RESUMO

Malignant ascites effusion (MAE) is a common complication of advanced malignant tumors with limited treatments. Euphorbia lathyris (EL) has a long history of application in patients with edema and ascites. Herein, we reported for the first time a mode in which EL and EL Pulveratum (PEL) spontaneously formed natural microemulsions (ELM and PELM) without the addition of any carriers and excipients, and found that the protein and phospholipid contained in them encapsulated fatty oil and diterpenoid esters through non-covalent interactions. The denaturation and degradation of protein in PELM resulted in stronger binding of diterpenoid esters to the hydrophobic region of protein, which facilitated the sustained and slow release of diterpenoid esters and improved their bioavailability in vivo, thereby retaining the efficacy of preventing MAE while alleviating the irritation of intestinal mucosa. The mechanism by which PELM retained efficacy might be related to increased feces moisture and urine volume, and decreased expression of AVPR2, cAMP, PKA and AQP3 in MAE mice. And its mechanism of reducing intestinal mucosal irritation was related to decreased cell apoptosis, amelioration of oxidative stress, elevation of mitochondrial membrane potential, and up-regulation of Occludin and Claudin-1 expression in IEC-6 cells. This nano-adjuvant-free natural microemulsions may be a promising therapeutic strategy in the field of phytochemistry for promoting the application of natural and efficient nano-aggregates spontaneously formed by medicinal plants in MAE, and provide a new perspective for advancing the development of the fusion of Chinese herbal medicine and nanomedicine and its clinical translation.

RESUMO

Pseudo-Meigs syndrome is a rare syndrome characterized by hydrothorax and ascites associated with pelvic masses, and patients occasionally present with elevated serum cancer antigen-125 (CA125) levels. Hydropic leiomyoma (HLM) is an uncommon subtype of uterine leiomyoma characterized by hydropic degeneration and secondary cystic changes. Rapidly enlarging HLMs accompanied by hydrothorax, ascites, and elevated CA125 levels may be misdiagnosed as malignant tumors. Here, we report a case of HLM in a 45-year-old Chinese woman who presented with ascites and hydrothorax. Preoperative abdominopelvic CT revealed a giant solid mass in the fundus uteri measuring 20 × 15 × 12 cm. Her serum CA125 level was elevated to 247.7 U/ml, while her hydrothorax CA125 level was 304.60 U/ml. The patient was initially diagnosed with uterine malignancy and underwent total abdominal hysterectomy and adhesiolysis. Pathological examination confirmed the presence of a uterine hydropic leiomyoma with cystic changes. After tumor removal, the ascites and hydrothorax subsided quickly, with no evidence of recurrence. The patient's serum CA125 level decreased to 116.90 U/mL on Day 7 and 5.6 U/mL on Day 40 postsurgery. Follow-up data were obtained at 6 months, 1 year, and 2 years after surgery, and no recurrence of ascites or hydrothorax was observed. This case highlights the importance of accurate diagnosis and appropriate management of HLM to achieve successful outcomes.

RESUMO

Introduction: Intra-tumoral B cells mediate a plethora of immune effector mechanisms with key roles in anti-tumor immunity and serve as positive prognostic indicators in a variety of solid tumor types, including epithelial ovarian cancer (EOC). Several aspects of intra-tumoral B cells remain unclear, such as their state of activation, antigenic repertoires, and capacity to mature into plasma cells. Methods: B lymphocytes were isolated from primary EOC tissue and malignant ascites and were maintained in cell culture medium. The stably maintained cell lines were profiled with flow cytometry and B cell receptor sequencing. Secreted antibodies were tested with a human proteome array comprising more than 21,000 proteins, followed by ELISA for validation. Originating tumor samples were used for spatial profiling with chip cytometry. Results: Antibody-secreting B lymphocytes were isolated from the ovarian tumor microenvironment (TME) of four different EOC patients. The highly clonal cell populations underwent spontaneous immortalization in vitro, were stably maintained in an antibody-secreting state, and showed presence of Epstein-Barr viral (EBV) proteins. All originating tumors had high frequency of tumor-infiltrating B cells, present as lymphoid aggregates, or tertiary lymphoid structures. The antigens recognized by three of the four cell lines are coil-coil domain containing protein 155 (CCDC155), growth factor receptor-bound protein 2 (GRB2), and pyruvate dehydrogenase phosphatase2 (PDP2), respectively. Anti-CCDC155 circulating IgG antibodies were detected in 9 of 20 (45%) of EOC patients' sera. Tissue analyses with multiparameter chip cytometry shows that the antibodies secreted by these novel human B cell lines engage their cognate antigens on tumor cells. Discussion: These studies demonstrate that within the tumor-infiltrating lymphocyte population in EOC resides a low frequency population of antibody-secreting B cells that have been naturally exposed to EBV. Once stably maintained, these novel cell lines offer unique opportunities for future studies on intratumor B cell biology and new target antigen recognition, and for studies on EBV latency and/or viral reactivation in the TME of non-EBV related solid tumors such as the EOC.

RESUMO

An immigrant woman in her 60s with a complex medical history and remote occupational exposure to patients with tuberculosis (TB) presented with abdominal pain, early satiety, bloating and weight loss. Physical exam showed abdominal distention and ascites. Diagnostic paracentesis revealed low serum ascites albumin gradient and elevated ascitic lymphocytic count. However, fluid cytology, bacterial and mycobacterial cultures were negative. An interferon-gamma release assay for TB was indeterminate. MRI of the abdomen and pelvis showed a thickened endometrial stripe. Endometrial biopsy demonstrated non-caseating granulomatous endometritis. No organisms were identified on Grocott methenamine silver or acid-fast bacilli special stains. A tissue block from the endometrial biopsy submitted for DNA sequencing was positive for mycobacterium tuberculosis (MTB) complex Urine mycobacterial cultures were obtained and the patient was started on isoniazid, rifampin, ethambutol and pyrazinamide, with significant improvement in her symptoms. Urine mycobacterial cultures were eventually positive for pansusceptible MTB.

RESUMO

INTRODUCTION: We aimed to demonstrate the sensitivity of frozen section for patients with adult granulosa cell tumor (AGCT) and analyze the clinico-pathological factors that may be associated with sensitivity. MATERIAL METHODS: This is a multicenter study including data of 10 Gynecological Oncology Departments. Frozen-section results of patients who had ovarian AGCT at the final pathology report were retrospectively analyzed. The relation between clinico-pathological characteristics such as age, tumor size, Ca-125 level, presence of ascites, omental metastasis, menopausal status and peritoneal cytology, and the sensitivity of frozen section in patients with AGCT were evaluated. The sensitivity of frozen section diagnosis was determined by comparing the frozen section result with the final pathological diagnosis. RESULTS: Frozen section results of 274 patients with AGCT were obtained. The median age of the patients was 52 years (range, 17-82 years). Totally, 144 (52.7%, n = 273) patients were postmenopausal. The median tumour size was 90 mm (range, 9-700 mm). The median preoperative Ca-125 level was 23 IU/mL (range, 2-995 IU/mL). The sensitivity of frozen section for detecting AGCT was 76.3%. Any association between the sensitivity of frozen section and menopausal status, presence of ascites, positive cytology, omental metastasis, tumor size, Ca-125 level, age could not be shown. CONCLUSION: It is important to know the diagnosis of AGCT intraoperatively, and we demonstrated the sensitivity of frozen-section for these tumors as 76.3%.

RESUMO

BACKGROUND: The management of malignant ascites is critical for treating patients with advanced pancreatic cancer. The purpose of this study was to assess the safety of cell-free and concentrated ascites reinfusion therapy (CART) and its impact on the prognosis of patients with advanced pancreatic cancer who have massive malignant ascites. METHODS: This study analyzed 47 procedures in 29 patients who underwent CART for ascites caused by pancreatic cancer between 2015 and 2022. Among them, 7 patients who received chemotherapy following CART were classified as the chemotherapy group, while 22 patients without chemotherapy after CART were classified as the palliative care group. RESULTS: Among the 47 procedures, adverse events (AEs) were observed in 9 procedures (19 %). Grade 2 adverse events were observed only in one procedure, manifested as fever. There were no grade 3 or 4 AEs, nor were there any treatment-related deaths. The median survival time was 4.0 months in the chemotherapy group and 0.7 months in the palliative care group (p = 0.004). The albumin level in the chemotherapy group was significantly higher than that in the palliative care group. CONCLUSION: CART is feasible and might be the optimal option to enable prolonged use of chemotherapy to improve the prognosis for late-stage pancreatic cancer patients.

RESUMO

Cats (Felidae) have become an integral part of many households. However, our understanding of the full spectrum of pathogens affecting cats (referred to as the infectome) is limited, mainly due to the inadequacy of commonly used diagnostic tools in capturing the complete diversity of potential pathogens and the prevalence of pathogen co-infections. In this study, we employed a meta-transcriptomic approach to simultaneously characterize the infectome contributing to different disease syndromes and to investigate spatial, demographic, and ecological factors influencing pathogen diversity and community composition in a cohort of 27 hospitalized cats and seven stray cats. We identified 15 species of pathogens, with Candidatus Rickettsia tarasevichiae and Tritrichomonas foetus representing potential spillover risks. Importantly, although most cases of ascites hyperplasia were explained by coinfection with multiple pathogens, we identified the potential novel clinical outcomes of M. aubagnense infection among cats. We demonstrated that the increase in infectome diversity can be explained by a variety of predictors including age growth, temperature increase, and a higher proportion of females, with age growth presenting the strongest effect. Fine-scale analysis indicated that a higher diversity of infectomes were harbored in young cats rather than adult ones. Our results demonstrated that most feline diseases are better explained by the presence of virus-bacteria or virus-virus coinfection. This study serves as a timely endorsement for clinical diagnosis by vets to consider the cause of a disease based on a panel of cryptical co-infecting pathogens rather than on individual infectious agents. IMPORTANCE: Frequent studies reported the risks of cats as an intermediate host of zoonotic pathogens (e.g., SARS-CoV-2). Cats have a physically close interaction with their owners through activities like petting, kissing, and being licked on the cheek and hands. However, there are still limited studies that systematically investigate the infectome structure of cats. In this study, we employed a meta-transcriptomics approach to characterize 15 species of pathogens in cats, with Candidatus Rickettsia tarasevichiae first characterizing infection in diseased cats. Most feline diseases were better explained by the presence of virus-bacteria or virus-virus coinfection. The increase in infectome diversity could be influenced by a variety of predictors including age growth, temperature increase, and a higher proportion of females. A higher diversity of pathogens was harbored in young cats rather than adults. Importantly, we showed the value of linking the modern influx of meta-transcriptomics with comparative ecology and demography and of utilizing it to affirm that ecological and demographic variations impact the total infectome.

RESUMO

Preeclampsia is a multisystem disorder associated with defective trophoblast invasion, maternal syndrome, and capillary endothelial leak. The presence of ascites/third space fluid accumulation increases the risk of maternal morbidity and mortality. The current criteria/guidelines of preeclampsia do not establish the presence of ascites as a marker of severity or recognize the timing and need for early delivery despite associated complications. Medline and Embase databases were searched to identify relevant literature, reported up to December 2023, regarding the pathophysiology, pregnancy outcome, and management of preeclampsia complicated with ascites. A total of 5 studies on pathophysiology and eight on pregnancy outcomes met the inclusion criteria, with 41 case reports on ascites in preeclampsia. The etiopathogenesis for the development of ascites in preeclampsia includes endothelial damage, capillary hyperpermeability, release of vasoconstrictive agents, reduced intravascular oncotic pressure, and raised intraabdominal pressure. The presence of ascites represents the extreme form of microvascular damage, which also correlates with the raised sFlt-1 levels in this condition. The adverse pregnancy outcomes include increased risk of congestive heart failure, eclampsia, renal failure, disseminated intravascular coagulation, acute respiratory distress syndrome, and maternal death. The presence of ascites in preeclampsia is associated with the deterioration of the maternal condition. Hence, it is indicative of preeclampsia with severe features and requires vigilant monitoring, and prompt delivery may be considered.

RESUMO

At least one-third of patients with epithelial ovarian cancer (OC) present ascites at diagnosis and almost all have ascites at recurrence especially because of the propensity of the OC cells to spread in the abdominal cavity leading to peritoneal metastasis. The influence of ascites on the development of pre-metastatic niches, and on the biological mechanisms leading to cancer cell colonization of the mesothelium, remains poorly understood. Here, we show that ascites weakens the mesothelium by affecting the morphology of mesothelial cells and by destabilizing their distribution in the cell cycle. Ascites also causes destabilization of the integrity of mesothelium by modifying the organization of cell junctions, but it does not affect the synthesis of N-cadherin and ZO-1 by mesothelial cells. Moreover, ascites induces disorganization of focal contacts and causes actin cytoskeletal reorganization potentially dependent on the activity of Rac1. Ascites allows the densification and reorganization of ECM proteins of the mesothelium, especially fibrinogen/fibrin, and indicates that it is a source of the fibrinogen and fibrin surrounding OC spheroids. The fibrin in ascites leads to the adhesion of OC spheroids to the mesothelium, and ascites promotes their disaggregation followed by the clearance of mesothelial cells. Both αV and α5ß1 integrins are involved. In conclusion ascites and its fibrinogen/fibrin composition affects the integrity of the mesothelium and promotes the integrin-dependent implantation of OC spheroids in the mesothelium.
