RESUMEN
BACKGROUND: Ex vivo liver resection and autotransplantation (ELRA) has shown promising outcomes in treating end-stage hepatic alveolar echinococcosis (AE). However, the actual benefits and risks remain unclear. This study aims to analyze the benefits and risks of ELRA. METHODS: This retrospective cohort analysis included 228 patients with end-stage hepatic AE who underwent ELRA or nonsurgical treatment between 2014 and 2020. Propensity score matching was used. Long-term survival was compared in the matched cohorts using Kaplan-Meier curves generated with the log-rank test. Short-term mortality in entire cohort was predicted based on the nonsurgical group, and the interaction between the predicted mortality risk and observed mortality was tested. Risk factors for postoperative major morbidity in the ELRA group were evaluated using logistic regression analyses. RESULTS: The long-term overall survival of the ELRA group was superior to that of the nonsurgical group (82.1% vs 19.1%, 5-year survival). Regarding short-term outcomes, the basic risk of 12-month mortality exerted a significant effect on the benefit of ELRA in entire cohort (per 1%, odds ratio, 1.043; 95% confidence interval [CI]: 1.007-1.082; Pâ =â .021). Patients with a predicted 12-month mortality risk >75% would significantly benefit from ELRA. Combined resection (hazard ratio [HR], 3.32; 95% CI: 1.01-10.99; Pâ =â .049) and overall surgery time (per hour, HR, 1.41; 95% CI: 1.09-1.82; Pâ =â .009) were identified as independent risk factors for postoperative major morbidity. CONCLUSIONS: ELRA was significantly beneficial in selected patients with end-stage AE compared with nonsurgical treatment. The timing of conducting ELRA remarkably affected the short-term risk of mortality and should be carefully determined.

BACKGROUND: The diffusion of laparoscopic radical surgery for hydatid liver echinococcosis remains limited. There are no published data on a comparative analysis of the immediate and long-term results of radical and conservative laparoscopic surgery for liver hydatid cysts. Comparison of the immediate and long-term outcomes after laparoscopic radical and conservative cystectomies was aimed. METHODS: HPB center (Center 1) and general surgery hospital in an endemic area (Center 2) participated in a retrospective study. Radical surgery included total, subtotal pericystectomy, and liver resection. Conservative surgery comprised cystectomy without/with partial pericystectomy. RESULTS: The total number of patients who underwent surgery for liver hydatid cysts was 213. Laparoscopic cystectomy was performed in 106 (50%) patients. This number included 47 radical laparoscopic cystectomy (Center 1). Conservative laparoscopic procedures were used in 59 patients (Center 2). Finally, twenty-seven pairs of patients were matched. Immediate outcomes were better for radical treatment in terms of severe morbidity, length of hospital stay, and time of abdominal drainage before and after PSM. The mean follow-up length was 23 (4-66) and 29 (6-66) months and the recurrence rate was 2% and 5% in groups of radical and conservative treatment respectively. No differences were found in 1-, 3-, and 5-year disease free survival. After second PSM for recurrence, 20 pairs were matched with no relapse of disease. CONCLUSION: Laparoscopic radical surgery leads to the better immediate outcomes and can be recommended as the preferred treatment option in a specialized HPB center. Conservative option is justified in general hospitals in endemic area for selected uncomplicated cysts.

Human cystic echinococcosis, caused by the larval stage of Echinococcus granulosus sensu lato, has been reported a near-cosmopolitan zoonotic disease. Various infiltrating immune cells gather around the lesion and produce a lesion microenvironment; however, cellular composition and heterogeneity in hepatic cystic echinococcosis lesion microenvironments are incompletely understood. Here, 81,865 immune cells isolated from peripheral blood, perilesion liver tissue, and adjacent normal liver tissue from four cystic echinococcosis patients were profiled using single-cell RNA sequencing. We identified 23 discrete cell populations and found distinct differences in infiltrating immune cells between tissue environments. Despite the significant similarity between perilesion and adjacent normal liver tissue-resident immune cells, the cellular proportions of type 2 innate lymphoid cells (ILC2s) and plasmacytoid dendritic cells (pDCs) were higher in perilesion liver tissue. Interestingly, the immunosuppressive gene NFKBIA was upregulated in these cells. Seven subsets of CD4+ T cell populations were found, and there were more regulatory-CD4+ T cells (Treg-CD4+) and Th2-CD4+ T cells in perilesion tissue than in adjacent normal tissue. There was close contact between CD4+ T cells and ILC2s and pDCs, which caused upregulation of genes related to positive immune activity in adjacent normal liver tissue. However, expression of genes related to immunosuppression, especially the immune inhibitory checkpoint gene NKG2A/HLA-E, was obviously higher in perilesion tissue, suggesting that cellular interaction resulted in an inhibitory microenvironment in the cystic echinococcosis (CE) lesion. This work offers new insights into the transcriptional heterogeneity of infiltrating immune cells in hepatic cystic echinococcosis lesion microenvironments at a single-cell level and provides potential target signatures for diagnosis and immunotherapies.

Positron emission tomography-computed tomography (PET-CT) with 18F-fluorodesoxyglucose (FDG) is the imaging modality of choice for assessing inflammation surrounding hepatic alveolar echinococcosis (AE) lesions. This study is the first to evaluate FDG uptake in hepatic AE (n = 51) based on the standardized uptake value (SUV) and to correlate the SUVs with primary morphology and calcification patterns, based on the Echinococcus multilocularis Ulm Classification for Computed-Tomography (EMUC-CT). Our results show that the SUVs were increased for lesions with EMUC-CT types I-IV primary morphology, compared to the surrounding healthy liver tissue (SUV = 2.5 ± 0.4; p < 0.05). Type IV lesions included, by far, the highest number of PET-negative lesions. A comparison of lesions with different primary morphologies showed clear differences. The highest SUVs were found for types I and III, and the lowest was found for type IV. Type IV lesions (SUV, 3.8 ± 1.5) showed significantly lower uptake compared to type I (SUV, 6.9 ± 3.5; p = 0.030) and type III (SUV, 7.4 ± 3.9; p = 0.031) lesions. For type II lesions, the results showed only a statistical trend (SUV, 6.1 ± 3.1; p = 0.073). Due to the small number of cases, an evaluation of type V (n = 1) lesions was not possible. The different SUVs of lesions with different primary morphologies, particularly the lower FDG uptake observed in type IV lesions, suggested that these SUVs might reflect different stages of the disease.

Although infrequent in the diagnostics areas, liver abscesses are of significant relevance, which is related to the high morbidity and mortality figures they can cause if they are not detected and treated in time. Although multiple operational classifications are described, the one most recognized for its usefulness is that related to its causative agent (pyogenic or bacterial infection, hydatid origin or secondary to infected hydatidosis, and amoebic or by invasive amebiasis). The objective of this article was to generate a study report regarding the morphological characteristics of liver abscesses, characterizing them according to their etiology, as well as describing their study and the latest recommended treatments.
Los abscesos hepáticos son entidades nosológicas de baja frecuencia, pero de significativa relevancia, la que se relacionada con las elevadas cifras de morbilidad y mortalidad que pueden causar si no son detectados y tratados a tiempo. Si bien se describen múltiples clasificaciones operacionales, aquella más reconocida por su utilidad es la relacionada a su agente causal (piógenos o bacterianos, hidatídicos o secundarios a hidatidosis infectada, y amebianos o por amebiasis invasora). El objetivo de este artículo fue generar un documento de estudio respecto de las características morfológicas de los abscesos hepáticos, caracterizándolos de acuerdo con su etiología, así como describir su estudio y tratamiento recomendado de acuerdo con el estado del arte.

Human alveolar echinococcosis (AE) is a lethal parasitic infectious disease which may lead to liver failure if left untreated. It is caused by the larval stage of the fox tapeworm Echinococcus multilocularis and usually develops a substantial infiltrative occupation in solid organs. During the infection, T helper subsets are known to play crucial role in crosstalk between the parasite and human host. Th9 cells, a new member of CD4(+) T cell family which is characterized by its specific cytokine IL-9 and transcription factors PU.1 and IRF-4, have been known recently to have a critical role in allergic diseases, and cancers as well as the parasitic infection. To assess the potential role of Th9 cells during the infection, the mRNA levels of IL-9, PU.1, and IRF-4 both in peripheral blood mononuclear cells and in liver tissues were, respectively, detected by using real-time PCR. The plasma concentration levels of IL-9 were detected by using enzyme linked immunosorbent assay (ELISA). Th9 related cytokine IL-9 and transcription factors PU.1 and IRF-4 mRNA levels elevated both in PBMCs, and in hepatic lesion and paralesion tissues in AE patients. This may facilitate the infiltrative growth of the parasite and its persistence in human host.

BACKGROUND: Hydatid recurrence after surgery is about 10 %. It still constitutes a problem both in terms of pathophysiology and management of recurrence. AIM: The aim of this study was to assess the management of abdominal hydatid recurrence after surgical treatment for liver hydatid cyst and to identify the predictive factors of recurrence. METHODS: We retrospectively included all the patients operated on between January 1, 2008, and December 31, 2012, in the Department "B" of Charles Nicolle Hospital (Tunisia), for abdominal hydatid recurrence. Sixteen men and 33 women, with a median age of 45 years, were included. For all patients, clinical variables and morphological and intra-operative characteristics concerning both the hydatid cysts previously treated and the recurrent cysts were collected. Surgical procedures were recorded as well as the immediate and long-term outcomes. Comparative studies were performed: "extrahepatic recurrence versus No," "peritoneal recurrence versus No," and "open approach versus laparoscopic approach." A univariate analysis followed by a multivariate analysis was carried out to determine predictive factors of hydatid recurrence. RESULTS: Comparative analysis showed that laparoscopic approach, segments II and III localization, and postoperative complications during the first intervention were associated with a greater number of both peritoneal and extrahepatic hydatid recurrence. Multivariate analysis retained the laparoscopic approach as a predictive factor of both peritoneal recurrence (OR 5.5; 95 % CI 1.56; p = 0.008) and abdominal extrahepatic recurrence (OR 3.54; 95 % CI 1.08; p = 0.035). CONCLUSION: Laparoscopic approach for the treatment of liver hydatid cysts was associated with a higher rate of extrahepatic and peritoneal recurrence than open.

We herein report a case of a young Japanese female who was confirmed to have cystic echinococcosis (CE) 1 stage based on the World Health Organization Informal Working Group on Echinococcosis pathological classification of CE, and she was also suspected to be infected with eggs of the G1 Echinococcus granulosus sensu stricto during her stay in the United Kingdom and therefore, suffered from synchronous pulmonary and hepatic CE. Oral albendazole was administered initially, but rupture of a lung hydatid cyst was observed. To avoid additional rupture, we performed two surgeries. CE is very rare in Japan; all CE cases in Japan during the past two decades have been confirmed to be imported, and almost all cases are hepatic CE. This case is the first case report of a Japanese patient who had concomitant giant lung and liver CE with early-stage CE1 and was successfully treated by surgery and pharmacotherapy with a serological follow-up.

We describe a patient with human immunodeficiency virus type-1 (HIV) infection and alveolar echinococcosis (AE) with a focus on two messages. Despite being severely immunocompromised over years the patient exhibited a long-term asymptomatic course of AE. This is in clear contrast to reports describing accelerated courses of AE in immunocompromised patients. The patient had therapeutic mebendazole drug levels with only 1/10 of the normal drug dose. He was co-treated with protease inhibitors for his HIV infection. These drugs are known as strong inhibitors of cytochrome P450 3A4 (CYP3A4)-dependent metabolism. We speculate that benzimidazoles and protease inhibitors interfere at the CYP3A4-level. The first report of co-infection of HIV and accelerated AE was in a young girl with an extremely low CD4 cell count and an abrogated lymphoproliferative responsiveness to parasite antigen stimulation. Since the CD4 cell count in our patient remained in the range of 27-150 cells/microl, we speculate that there was a critical threshold of immunosupression for constraining AE. Initial treatment with albendazole for AE added to the current highly active antiretroviral treatment (HAART), and suppressive toxoplasmosis therapy became complicated by pancytopenia. After full recovery of the bone marrow, mebendazole was introduced with a new HAART and the previously prescribed toxoplasmosis maintenance therapy. Surprisingly, efficient mebendazole levels were achieved with an uncommonly low dose. These observations suggest that the benzimidazoles, albendazole and mebendazole, may interact with protease inhibitors, which are known for their strong inhibition of the CYP3A4.

Twelve pregnant women with hydatid disease are presented with median age of 29; 11 (91.7%) had a liver cyst and one (8.3%) had a kidney cyst as the primary disease location. Four (33.3%) had additional cysts located in the pelvis, peritoneal cavity and/or spleen; eight (66.7%) had two or more abdominal cysts. Three patients (25.0%) had surgery at the 3rd month after delivery and nine (75.0%) during their pregnancy. There was no histological evidence of hydatid disease in placentas, and no serological evidence of echinococcosis in the newborns was confirmed. One patient died after surgery. After a mean follow-up time of 39.5 months, we found one recurrent case of pelvic hydatid disease. Management of abdominal echinococcosis during pregnancy is an uncommon and difficult problem owing to the serious potential risks for mother and child.
