Portal hypertension as a result of the incomplete surgically treated advanced alveolar echinococcosis: a case description

Ex vivo Liver Autotransplantation for Alveolar Echinococcosis with Brain and Lung Metastases: A Case Report

Ex vivo liver resection and autotransplantation (ELRA) in extensive abdominal alveolar echinococcosis (AE) is a relatively rare treatment. We present the first case, ever reported in Kazakhstan, of successfully performed ELRA of a patient with extensive abdominal AE with invasion into the inferior vena cava (IVC). A 64-year-old woman was diagnosed with AE of the brain, alveococcectomy from the left frontal lobe was performed. At the same time, liver AE metastased to the lungs and brain was diagnosed. The patient was admitted to our center for the following surgical treatments: (1) laparotomy, (2) extended left hemihepatectomy with resection of IVC ex vivo, (3) plastic surgery of IVC with a synthetic prosthesis, (4) orthotopic transplantation of the remnant right lobe of the liver. The postoperative period proceeded smoothly. The patient was mechanically ventilated for 1.5 days and prescribed strict bed rest with in-bed activity for up to 11 days. Empirical antibiotic therapy was initiated as follows: meropenem 1000 mg three times a day for 10 days, omeprazole 40 mg once a day for 14 days, anticoagulant therapy was not administered in the first post-operation day due to high risk of bleeding. Clexane was prescribed subcutaneously once a day: 0.2 mL for 2 days, then 0.4 mL for next 10 days. Daily transfusion of 100 mL of 10% Albumin was performed to prevent hypoalbuminemia. Drainage systems were removed on the 9th day. On the 12th day, the patient was transferred from the intensive care unit to a hospital room, and discharged with improvement on the 20th day. During a 6-month follow-up, no relapse was observed. Radical surgery for widespread AE, in this case - ELRA, is the preferred treatment, since it does not require immunosuppressive therapy and is quite feasible even with invasion of the portal vein bifurcation, IVC and hepatocaval confluence.

Young Age of Alveolar Echinococcosis Patient in Armenia: A Case Report

Human alveolar echinococcosis (AE) remains a serious public health concern in endemic areas and a challenge for clinicians. Here a confirmed case of human AE in a patient from Armenia who had not visited a known Echinococcus multilocularis endemic area is reported. In October 2012, a 12-year-old girl from a little Armenian village, presented with paroxysmal pain in the right lumbar area to the children's medical center (MC). The girl mentioned having close contact with an animal, like a cat. She was admitted to the surgical department with a diagnosis of a malignant liver tumor in the right lobe. In November 2012, the patient underwent laparotomy, removal of the hepatic lesion and abdominal cavity drainage. The histopathological examination of the biopsy material confirmed the main diagnosis of liver AE with suppurative lesions. The patient was given albendazole (ABZ) following 20 days in the hospital, but she stopped receiving the preventive chemotherapy at home and even missed the dispensary visits. It later caused complications, and in July 2016, the child had once again surgery. In January 2017, the child was readmitted to the MC with no content from the external biliary drainage tube in the previous 6 hours. Bile flow improved after flushing the drainage with saline solution and suturing the enterostomy tube. In February 2017, the child visited MC for examination, and the drainage of the bile ducts was blocked, although she had neither discomfort nor jaundice. It was recommended to continue the patient's follow-up, to receive ABZ and to undergo a liver transplant surgery.

Risk Factors and the Character of Clinical Course of the Echinococcus multilocularis Infection in Patients in Poland

Alveolar echinococcosis (AE) is a chronic zoonotic disease caused by the larval form of Echinococcus multilocularis. In humans, it may become a serious chronic infection of the liver which resembles a slow malignant process leading to death when untreated. The aim of the study was an assessment of the risk factors of the E. multilocularis infections and the description of AE clinical course in the group of 36 patients with confirmed AE, hospitalized at the Department and Clinic of Tropical and Parasitic Diseases, Poznan University of Medical Sciences between 2013 and 2022. Among the study participants, most patients cultivated land, bred livestock, worked in the forest, or were employed in animal shelters. The E. multilocularis infection was diagnosed based on imaging and immunoassay techniques within 6 months in the majority of patients hospitalized in the Department. All patients hospitalized in the Department initiated anti-parasitic therapy at the moment of the diagnosis. Pharmacological treatment combined with surgery was applied in most of the study participants, who were presented with more advanced stages of infection. We conclude the following: 1. For humans in the risk group, regular abdominal imaging examinations and the detection of specific antibodies against E. multilocularis are recommended. 2. Regular screening tests in the hyperendemic areas of AE would increase the early detection of the disease and to improve the clinical prognosis in this extremely life-threatening parasitic disease.

Chemical and physical features of biological fluids in treatment of hydatid disease

The aim of this paper is to better understand the dynamics of crystallogenic and starting activity in biological fluids of patients throughout surgery and the late postoperative phase in alveococcosis. Samples of saliva from 22 individuals with alveococcosis were included in the research. Biological fluid samples were taken at the time of admission and before the patient was discharged. Following that, slides were made utilizing the teziocrystalloscopy method, which incorporates the investigation of the crystal forming activity of mixed saliva with its starting characteristics using a 0.9 percent sodium chloride solution as the foundation ingredient. Using our own set of criteria, we evaluated the outcomes of crystalloscopic and tezigraphic experiments. Specrophotometric examination of tezigraphic and crystalloscopic facies was done using a PowerWave XS microplate spectrophotometer at wavelengths of 400, 350, and 300 nm to augment the results from ocular morphometry of dried saliva micro slides. Surgical therapy results in a partial normalization of physical and chemical parameters, as well as the composition of the patient's biological fluids after the patient is discharged from the hospital.
