Genetic Diversity of Hepatic/Non-Hepatic Cystic Echinococcosis in Baqiyatallah Hospital, Tehran, Iran.

ABSTRACT: Background:Cystic echinococcosis (CE) is a worldwide zoonotic helminthic disease caused by the larval stage of Echinococcus granulosus. The infection is particularly important in terms of economic and medico-veterinary aspects in endemic areas including Iran. Considering the possibility of organ-tropism in E. granulosus strains, the present study was aimed to identify the genotypes of E. granulosus in different organs involved in patients, undergone surgery in Baqiyatallah Hospital, Tehran, Iran from 2005-2015. Methods:Overall, 29 formalin-fixed paraffin-embedded tissues (FFPT) from patients with histologically confirmed CE including liver (N: 14) lungs (N: 6) abdomen (N: 2), pancreas (N: 2) and each of spleen, gallbladder and, muscles (N: 1) plus unknown organs (N: 2) were used and genetically characterized using polymerase chain reaction, followed by partial sequencing of mitochondrial cytochrome c oxidase gene subunit 1(cox1) and analyzed. Results:Nineteen out of 29 isolates including liver (N: 6) lungs (N: 4) abdomen (N: 2), pancreas (N: 2) and each of spleen, gallbladder, and muscle (N: 1), unknown organs (N: 2) obtained from paraffin-embedded blocks of human CE created an acceptable sequence in two directions. All 19 isolates regardless of the organ involved were recognized as E. granulosus sensu stricto (G1). Conclusion:The sequence alignments of the isolates displayed two profiles. All sequenced samples showed E. granulosus sensu stricto (G1) with no organ-related genotype.

Project description:ObjectiveThe coronavirus disease 2019 (COVID-19) has become a global pandemic. Timely and effective predictors of survival and death rates are crucial for improving the management of COVID-19 patients. In this study, we evaluated the predictors of mortality based on the demographics, comorbidities, clinical characteristics, laboratory findings, and vital signs of 500 patients with COVID-19 admitted at Imam Khomeini Hospital Complex, the biggest hospital in Tehran, Iran.MethodsFive hundred hospitalized laboratory-confirmed COVID-19 patients were included in this study. Subsequently, electronic medical records, including patient demographics, clinical manifestation, comorbidities, and laboratory test results were collected and analyzed. They were divided into two groups: expired and discharged. Demographics, clinical, and laboratory data were compared among the two groups. The related factors with death in the patients were determined using univariate and multivariate logistic regression approaches.ResultsAmong the 500 hospitalized patients, most patients were male (66.4% versus 33.6%). The expired group had more patients ⩾70 years of age compared with the discharged group (32.9% versus 16.3%, respectively). Almost 66% of the expired patients were hospitalized for ⩾5 days which was higher than the discharge group (26.9%). Patients with a history of opium use in the expired group were significantly higher compared to the discharged group (14.8% versus 8.6%, p = 0.04) as well as a history of cancer (15.5% versus 4.7%, p < 0.001). Out of the 500 patients with COVID-19, four patients (2.6%) were HIV positive, all of whom expired. Dyspnea (76.4%), fever (56.6%), myalgia (59.9%), and dry cough (67%) were the most common chief complaints of hospitalized patients. Age ⩾70 years (adjusted odds ratio = 2.49; 95% confidence interval, 1.02-6.04), being female (adjusted odds ratio = 2.06; 95% confidence interval, 1.25-3.41), days of hospitalization (adjusted odds ratio = 5.73; 95% confidence interval, 3.49-9.41), and having cancer (adjusted odds ratio = 3.23; 95% confidence interval, 1.42-7.39) were identified as independent predictors of mortality among COVID-19 patients.ConclusionDischarged and expired COVID-19 patients had distinct clinical and laboratory characteristics, which were separated by principal component analysis. The mortality risk factors for severe patients identified in this study using a multivariate logistic regression model included elderly age (⩾70 years), being female, days of hospitalization, and having cancer.

Project description:ObjectiveSurgery is the mainstay of hepatic cystic echinococcosis (HCE). The conservative surgery of HCE carries a non-negligible risk of recurrence and significant morbidity, dominated by Deep Surgical Site Infections (DSSI). To address these issues, we have improved and standardized this technique, which could reduce complications and achieve better postoperative outcomes.Patients and methodsWe conducted a prospective study from June 2017 to June 2022 involving of patient operated using a standardized open technique for uncomplicated HCE at Habib Bourguiba University Hospital, Sfax, Tunisia. The aim was to obtain results at least similar to radical management in terms of DSSI. Patients with large cystobiliary fistulas or patients with complicated cysts were excluded.ResultsFifty patients with 106 cysts were operated using the standardized technique comprising of liver mobilization, intraoperative ultrasound, systematic methylene blue injection to detect cystobiliary fistulas and omentoplasty. The median age of the patients was 44(semi-interquartile range: 16) years. The main symptom described by the patient was pain in 43 cases (86%). An abnormal liver test was found in 20 cases (40%). On imaging studies, the cyst had a median size of 7.4(3.0) cm. Cyst of the hepatic dome accounted for 38 cases (35.8%) with most cysts being situated in the right hemi-liver. Visual inspection of the cavity and Methylene blue testing allowed for the discovery of 57 cysts (53.7%) that had cystobiliary fistulas that were sutured. Omentoplasty was performed in 77 cysts (72.6%). Postoperatively, only 2 cases (1.9%) developed a DSSI in the form of an external bile leak with resolved with conservative management. No case of recurrence was found after a median follow-up of 24 months.ConclusionThe standardized conservative surgical technique, in selected patients, shows promise in reducing DSSI rates and overall morbidity, and achieve as equally good result as radical management.
