Long-term outcomes of patients with 10 or more colorectal liver metastases.

BACKGROUND: Although the number of colorectal liver metastases (CLM) is decreasingly considered as a contraindication to surgery, patients with 10 CLM or more are often denied liver surgery. This study aimed to evaluate the outcome after liver surgery and to identify prognostic factors of survival in such patients. METHODS: The study population consisted of a multicentre cohort of patients with CLM (N=12 406) operated on, with intention to resect, from January 2005-June 2013 and whose data were prospectively collected in the LiverMetSurvey registry. RESULTS: Overall, the group ⩾10 CLM (N=529, 4.3%) experienced a 5-year overall survival (OS) of 30%. A macroscopically complete (R0/R1) resection (72.8% of patients) was associated with a 3- and 5-year OS of 61% and 39% vs 29% and 5% for R2/no resection patients (P<0.0001). At multivariate analysis, R0/R1 resection emerged as the strongest favourable factor of OS (HR 0.35 (0.26-0.48)). Other independent favourable factors were as follows: maximal tumour size <40 mm (HR 0.67 (0.49-0.92)); age <60 years (HR 0.66 (0.50-0.88)); preoperative MRI (HR 0.65 (0.47-0.89)); and adjuvant chemotherapy (HR 0.73 (0.55-0.98)). The model showed that 5-year OS rates of 30% was possible provided R0/R1 resection associated with at least an additional favourable factor. CONCLUSIONS: Liver resection might provide long-term survival in patients with ⩾10 CLM staged with preoperative MRI, provided R0/R1 resection followed by adjuvant therapy. A validation of these results in another cohort is needed.

[Religious and cultural aspects of organ transplantation]. / Aspects religieux et culturels liés à la transplantation d'organes.

The number of transplantations is mainly limited by the shortage of organs, thereby leading to potentially lethal delays for patients registered on waiting lists. Among the causes of refusals of organ donation, religious reasons are often advocated. In order to make the point, we organized a debate between representatives of secularism ( " laïcité ") and of the most represented religions in Belgium, i.e. catholic, Islamic and Judaic. Even though the representation of death was variable, organ donation is authorized and even encouraged by the fundamental texts. Refusals of organ donation result more often from personal interpretations by local preachers. Therefore, the gathering of political and religious authorities in order to promote organ donation is desirable instead of sowing doubt for pseudo-religious reasons.

En médecine de transplantation, la pénurie d'organes représente le principal obstacle et cause de retard aux greffes vitales pour les receveurs inscrits sur liste d'attente. Parmi les causes de refus de don d'organes, des raisons d'ordre religieux sont souvent invoquées. Afin de faire le point sur cette problématique, nous avons organisé un débat rassemblant des représentants de la laïcité et des religions monothéistes les plus représentées en Belgique : catholicisme, islam, judaïsme. Il est apparu que, si la représentation de la mort varie selon les courants, le don d'organes est en fait autorisé, voire encouragé par les textes fondateurs des trois religions. Les refus sont plutôt le fait d'une interprétation personnelle par des prédicateurs. Dès lors, il serait judicieux de rassembler les forces politiques et spirituelles afin de promouvoir le don d'organes plutôt que de semer le doute à son sujet sous des prétextes pseudo-religieux.

Nonalcoholic fatty pancreas disease and Nonalcoholic fatty liver disease: more than ectopic fat.

OBJECTIVE: The aim of this study was to evaluate the metabolic effects of fatty pancreas (nonalcoholic fatty pancreas disease - NAFPD) in a group of obese paediatric patients with nonalcoholic fatty liver disease (NAFLD). METHODS: We included 121 consecutive children with echographic evidence of hepatic steatosis. All patients underwent to abdominal ultrasound to evaluate pancreatic echogenic pattern. We divided the patients into two groups on the basis of the presence of fatty pancreas. In all patients liver function tests, lipid and gluco-insulinemic profile were evaluated. A selected subset of patients (67) underwent to liver biopsy. RESULTS: Of these 121 patients, 58 showed NAFPD and 63 patients exhibited a normal pancreatic echogenic pattern. No differences were found in age, transaminases serum levels, lipid profile and pancreatic enzymes between the two groups. The patients with NAFPD had a significantly higher z-BMI, fasting insulin, insulin resistance (HOMA-IR) and lower ISI respect to the group without fatty pancreas. The patients with fatty pancreas showed a more advanced form of liver disease, with higher values of fibrosis, ballooning and NAS score with respect to the group without NAFPD. CONCLUSIONS: Our study demonstrated that NAFPD is a frequent condition in obese paediatric patients affected by NAFLD. Our data suggest that pancreatic fat should not be considered an inert accumulation of fat, but as an additional factor able to affect glucose metabolism and severity of liver disease, increasing the risk of develop metabolic syndrome.

Histopathological growth patterns of neuroendocrine tumor liver metastases.

Histopathological growth patterns (HGPs) of liver metastases represent a potential biomarker for prognosis after resection. They have never been studied in neuroendocrine tumor liver metastases (NETLM). This study evaluated if distinct HGPs can be observed in resected NETLM and if they have prognostic value. Sixty-three patients who underwent resection of NETLM between 01-01-2001 and 31-12-2021 were retrospectively included. HGPs were scored on Haematoxylin&Eosin slides using light microscopy, distinguishing desmoplastic- (dHGP), pushing- (pHGP) and replacement HGP (rHGP). Average HGP scores were calculated per patient. Each patient was classified according to predominant HGP. Overall and Disease-Free Survival (OS and DFS) were evaluated through Kaplan-Meier analysis and Cox regression. Eighteen patients had predominant dHGP (29%), 33 had predominant pHGP (52%) and 11 had predominant rHGP (17%). One patient had mixed HGP (2%). Five-year OS was 76% (95%CI: 66-87%) for the overall cohort. Five-year OS was 92% (95%CI: 77-100%) for dHGP, was 73% (95%CI: 59-91%) for pHGP, 50% (95%CI: 25-100%) for rHGP. Five-year DFS was 39% (95%CI: 19-83%) for dHGP, 44% (95%CI: 27-71%) for rHGP and 50% (95%CI: 23-100%) for pHGP. There was no significant association between HGP and OS or DFS in multivariable analysis. Distinct HGPs could be identified in NETLM. In patients who underwent resection of NETLM, no association was found between HGPs and postoperative survival. Half of the patients with NETLM have a predominant pushing growth pattern, which is a rare growth pattern in liver metastases from breast and colorectal cancer.

Acoustic radiation force impulse (ARFI) imaging with Virtual Touch Tissue Quantification in liver disease associated with cystic fibrosis in children.

PURPOSE: Cystic-fibrosis-associated liver disease (CFLD) may lead to portal hypertension (PHT) and cirrhosis. Clinical signs and biochemistry of liver involvement are not discriminating. The aim of the study was to evaluate the performance of acoustic radiation force impulse (ARFI) with virtual tissue quantification in comparison with clinical signs, biochemistry and standard hepatic ultrasound (US) patterns. MATERIALS AND METHODS: Virtual Touch Tissue Quantification, an implementation of US ARFI with shear-wave velocity (SWV) measurements was used in 75 children with cystic fibrosis (CF) and suspected CFLD to quantify hepatic stiffness. In each patient, ten measurements of SWV were performed on the right hepatic lobe. Patients were also evaluated by standard diagnostic tools (standard US, liver- and lung function tests, oesophagogastroscopy). RESULTS: Among CF patients, median SWV was significantly higher in patients with clinical, biochemical and US signs of hepatic involvement than in patients without US evidence of liver disease 1.08 m/s [(95% confidence interval (CI), 1.02-1.14]. Median SWV values in patients with portal hypertension, splenomegaly and oesophageal varices were 1.30 (95% CI, 1.17-1.43), 1.54 (95% CI, 1.32-1.75) and 1.63 (95% CI, 1.26-1.99), respectively. Differences were significant (p<0.001). CONCLUSIONS: ARFI is an innovative screening technique able to help identify CFLD in children.

[Multidisciplinary management of hepatocellular carcinoma in cirrhotic patients]. / Traitement du carcinome hépato-cellulaire chez le patient cirrhotique: la nécessité d'une approche pluridisciplinaire.

The treatment of hepatocellular carcinoma (HCC) in cirrhotic patients is challenging: the incidence is increasing, the cirrhosis dramatically limits the tolerance to treatment possibilities, there are many therapeutic modalities but resources are limited, namely in the context of organ shortage for transplantation. Liver transplantation (LT) is the optimal treatment as it combines the largest tumor resection possible and the correction of the underlying liver disease. Due to organ shortage however, LT is reserved for early-stages HCC. Surgical resection and radiofrequency destruction represent potentially curative options in highly selected patients. Arterial embolizations, chemo- or radio-embolizations, allow local tumor control but are not curative. These techniques could be performed before surgical resection or LT, to downstage the tumor and/or to control tumor progression while waiting for a graft. Finally, sorafenib is the only systemic treatment which has shown a survival benefit in advanced HCC. The benefit of combination of sorafenib and surgical treatments remains undetermined. The challenge in the management of HCC in cirrhotic patients is to integrate both individual (age, comorbidities, cirrhosis stage, tumor stage, specific contraindications to LT, etc.) and collective variables (expected waiting time before LT) to determine the best therapeutic option for each patient. In this process, multidisciplinarity is a key for success.

Case report: Sclerosed hemangioma of the liver: A diagnostic challenge.

Hemangiomas are the most common noncystic benign hepatic tumors and are usually incidentally discovered during routine radiological examinations. The diagnosis of hepatic hemangiomas with a typical presentation is generally easy with plain and cross-sectional imaging; however, it can be complicated when hemangiomas undergo histological changes such as fibrosis. Sclerosed hepatic hemangioma (SHH) is the extreme presentation of this fibrotic process. These atypical lesions can be misdiagnosed as primary hepatic malignancies or metastasis. Their diagnosis is established by histological examination. We report the case of a patient with an SHH, which was misdiagnosed as an intrahepatic cholangiocarcinoma. This article's aim is to draw attention to this infrequent pathology and underline the features of this benign tumor that could suggest its diagnosis prior to surgery to avoid unnecessary hepatic resections.

Clinical and microbiological monitoring of Cystic Fibrosis patients, three years of follow-up via Tele-Medicine: an empirical research.

OBJECTIVES: Evaluation of the effectiveness of home care through a telemonitoring system in reducing the incidence of new colonization by Pseudomonas Aeruginosa in a population of patients with Cystic Fibrosis (CF) followed by the CF clinic of the Bambino Gesù Hospital in Rome over a period of 36 months. MATERIALS AND METHODS: Two groups of patients were recruited, homogeneous for age, sex, BMI, FEV1, prevalence of CF-related Diabetes and CF-related Hepatopathy, access to new therapies with modulators: a) an IN group (N = 44 ) followed through a home telemonitoring system, b) an OUT control group (N = 110) followed according to the standards of care. The following parameters were detected for all patients: pulmonary colonization of the lungs, number and type of hospital admissions, respiratory function, BMI. RESULT: The OUT group had a statistically significant increase in the prevalence of Pseudomonas Aeruginosa infections during the observation period. Furthermore, a significant decrease in lung function assessed through FEV1 was also observed in the OUT group. CONCLUSION: Adolescent and adult patients belonging to the CF center who are not followed through the dedicated home telemonitoring service show, in the three-year period 2017-19, an increase in Pseudomonas Aeruginosa infections and a greater decrease in respiratory function. The use of telemedicine in CF is therefore an effective system not only in monitoring the disease but also as a treatment strategy, in the context of an evolving multidisciplinary model. As advantages, telemedicine can reduce the number of Pseudomonas Aeruginosa lung infections and the greater stability of respiratory function over time.

Liver transplantation during the COVID-19 epidemic : recommendations from the Belgian Liver Intestine Transplant Committee (BeLIAC).

Since January 2020, the Novel Coronavirus Disease 2019 (COVID-19) pandemic has dramatically impacted the world. In March 2020, the COVID-19 epidemic reached Belgium creating uncertainty towards all aspects of life. There has been an impressive capacity and solidarity of all healthcare professionals to acutely reconvert facilities to treat these patients. In the context of liver transplantation (LTx), concerns are raised about organ donation shortage and safety, the ethics of using limited healthcare resources for LTx, selection criteria for LTx during the epidemic and the risk of de novo COVID-19 infection on the waiting list and after LTx. BeLIAC makes several recommendations to try to mitigate the deleterious effect that this epidemic has/will have on donation and LTx, taking into account the available resources, and trying to maximize patients and healthcare professionals' safety.

Induction of tolerance in solid organ transplantation: the rationale to develop clinical protocols in liver transplantation.

Minimization or withdrawal of immunosuppressive treatments after organ transplantation represents a major objective for improving quality of life and long-term survival of grafted patients. Such a goal may be reached under some clinical conditions, particularly in liver transplantation, making these patients good candidates for tolerance trials. In this context in liver transplantation, the central questions are (1) how to promote the natural propensity of the liver graft to be accepted, (2) which type of immunosuppressive drug should be used for induction and maintenance, and (3) which biomarkers could be used to discriminate tolerant patients from those requiring long-term immunosuppression. Induction therapies using aggressive T-cell-depleting agents may favor graft acceptance. However, persistent and/or rapidly reemerging cell lines, such as memory-type cells or CD8(+) T cells, could represent a significant barrier for induction of tolerance. The type of maintenance drugs also remains questionable. Calcineurin inhibitors may be eventually deleterious in the context of tolerance protocols, through inhibitory effects on regulatory T cells, that are not observed with rapamycin. In conclusion, significant efforts must be made to achieve reliable strategies for immunosuppression minimization or withdrawal after organ transplantation into the clinics.

Cholecystectomy in cirrhotic patients: pitfalls and reasonable recommendations.

Cholecystectomy in cirrhotic patients remains a high risk procedure. The recent literature was reviewed in the objective to elaborate (evidence-based) recommendations for therapeutic decision. In patients with Child Pugh A or B cirrhosis, the laparoscopic approach should be preferred as it is associated with reduced morbidity and mortality as compared with open surgery (level B). In patients with decompensated Child Pugh C cirrhosis, the scarcity of literature data renders much more hazardous the definition of robust recommendations. In these patients, two options have to be considered beyond early laparoscopic cholecystectomy: first, a delayed surgery, in order to improve the preoperative patient's general condition and namely the coagulation, and second, a percutaneous drainage in very severe cases (level C).

Peripheral cholangiocarcinoma with endoluminal tumor thrombus in main bile duct mimicking a Klatskin tumor.

BACKGROUND: Peripheral cholangiocarcinoma with endobiliary thrombus could be confused with Klatskin tumor, eventually leading to inappropriate therapeutic decision. CASE REPORT: A 56-year-old man presented with an obstructive jaundice. Preoperative magnetic resonance imaging (MRI) showed a segment 7 liver tumor associated with a complete stop at the biliary bifurcation compatible with a Klatskin tumor. Surgical exploration revealed that biliary obstruction was caused by endobiliary tumor-related thrombus. A right hepatectomy was performed, allowing complete endobiliary thrombus extraction. At pathology, a T2N0 intrahepatic cholangiocarcinoma was demonstrated. No adjuvant chemotherapy was given and currently, 22 months after surgery, the patient remains disease free. DISCUSSION: This case underlines the fact that intraductal growth of peripheral cholangiocarcinoma does not represent a contraindication for surgical treatment. MRI could be useful to differentiate such presentation of peripheral cholangiocracinoma from Klatskin tumor and orientate the surgical treatment.

Diagnosis of atypical CF: a case-report to reflect.

Non-classic Cystic Fibrosis (CF) still represents a difficult entity to diagnose. We present a case of two sisters affected by mild pulmonary symptoms started at puberty, carriers of the F508del mutation associated with the T5TG13 combination. We discuss the clinical utility of TG repeat testing in individuals carrying the T5 variant. Furthermore, this case-report leads to reflect on the natural history of CF and the correct management of its atypical forms.

Liver transplantation for acute liver failure in adults.

Acute liver failure is a challenging clinical condition, associated with high morbidity and mortality. In well-selected patients, LT (LT) is the only therapeutic which has been demonstrated to improve patient survival. Clichy and King's College criteria are the two mains scoring systems used to select the patients for liver transplantation. Both models achieve high specificity but remain associated with limited negative predictive value. Several other predictive factors have been evaluated, but none of them have been strongly validated so far. Globally, whole LT appears as the procedure of choice for patients within Clichy and/or King's College criteria. Due to the severity of the disease and its multisystemic consequences, the results of LT for fulminant liver failure remain inferior to those obtained in elective indications. Accord-ing to local conditions, namely expected waiting time before urgent transplantation and surgical expertise, living donor transplantation and auxiliary transplantations appear as valuable alternatives. These techniques have the respective potential advantages to limit the waiting period before transplantation and to avoid the need for lifelong immunosuppression when native liver recovers, but overall results remain inferior to those obtained with whole LT.

Implementing carrier screening for cystic fibrosis outside the clinic: ethical analysis in the light of the personalist view.

BACKGROUND: Cystic Fibrosis (CF) is an autosomal recessive genetic disease. Two models for screening CF are normally used: newborn screening and population-based CF carrier screening. In turn, there are three main models of population-based CF carrier screening: prenatal carrier screening, preconception carrier screening, and carrier screening outside clinical settings. AIM: To evaluate, in the light of the personalist view, the use of carrier screenings for CF outside the clinic, i.e. in non-clinical settings, such as school and workplaces. METHODS: Analysis has been carried out according to the "Personalist approach" (also called "Triangular model"), an ethical method for performing ethical analysis within HTA process. It includes factual, anthropological and ethical data in a ''triangular'' normative reflection process. FINDINGS: Implementing carrier screening for cystic fibrosis outside the clinical settings allows acquisition of knowledge for informing reproductive choices, that can be considered as valuable; benefit-risk ratio seems to be not much favorable; autonomous and responsible decisions can be taken only under certain conditions; economic advantage is difficult to determine; therefore, from a personalist view, implementing carrier screenings outside the clinic seems not to be ethically justified. CONCLUSIONS: In accordance with the personalist perspective, public health programs providing carrier screenings outside the clinic should not be implemented.

A rapid test of alloreactivity based on interleukin-2 mRNA expression might identify liver transplant recipients with donor-specific hyporesponsiveness.

BACKGROUND: Immunosuppression withdrawal is feasible in some liver transplant (OLT) recipients but may lead to severe rejection in others, underlying the need for reliable biomarkers to identify patients with tolerant profile in whose weaning/withdrawal could be safely proposed. We evaluated the value of real-time polymerase chain reaction (PCR)-based measurement of interleukin (IL)-2 mRNA in mixed lymphocyte reaction (MLR) to monitor in vitro anti-donor reactivity in OLT patients. METHODS: MLR were performed in three patients undergoing living donor OLT using a tolerogenic protocol including donor stem cells. IL-2 mRNA production in MLR was measured by PCR at several intervals after OLT. RESULTS: In the early posttransplant period, three patients presented with global immunodeficiency, as indicated by low IL-2 mRNA production against both donor and third-party antigens. In the two patients who has immunosuppression successfully withdrawn, donor-specific hyporesponsiveness was observed thereafter: IL-2 mRNA production against donor cells remained low, while IL-2 mRNA production against a third-party antigen-presenting cells progressively recovered. No such modulation of the anti-donor response was observed in the patient in whom withdrawal led to rapid rejection. CONCLUSION: Measurement of IL-2 mRNA production in MLR might prefer a tool to monitor anti-donor reactivity after OLT for decisions to minimize or withdraw immunosuppression in patients displaying donor-specific hyporesponsiveness.

Use of marginal donors for liver transplantation: a single-center experience within the Eurotransplant patient-driven allocation system.

BACKGROUND: Due to the organ shortage, marginal donors are increasingly used in liver transplantation (OLT). These grafts may be safely used in less critical recipients but, the real influence of extended donor criteria (EDC) remains uncertain when graft-recipient matching is not applied. Our study analyzed the impact of EDC on initial graft function within the Eurotransplant patient-driven allocation system. PATIENTS AND METHODS: We reviewed 70 OLT performed between 2004 and 2006. The impact of the following EDC were analyzed: age > 60; intensive care unit (ICU) stay > 4 days; peak serum Na(+) > 160 mEq/L; body mass index (BMI) > 30; cardiac arrest with cardiopulmonary resuscitation, and high doses of vasopressors. Early graft function, as defined according to peak transaminase level and spontaneous prothrombin time within the first 5 posttransplant days, was compared between the donors with none or one criterion (group A = 39) and those with >1 criterion (group B = 31). RESULTS: The most frequent EDC were high vasopressor use, ICU stay > 4 days and BMI > 30, were present in respectively 44%, 27%, and 16% of the donors. No EDC were present in 13 donors, one in 26, three in eight, and four in three. Demographics and origin and severity of the liver disease were similar in both groups. We failed to observe significant differences in initial graft function. CONCLUSION: The presence of EDC did not significantly affect early graft function in a population where donor and recipient were not matched. While this observation must be confirmed in a multicenter analysis, it tends to support the use of marginal liver grafts, even in patient-driven allocation systems.

A pilot trial on safety and efficacy of erythrocyte-mediated steroid treatment in CF patients.

BACKGROUND: Chronic neutrophil inflammation of the respiratory tract tissues plays a key role in the pathogenesis and in prognosis of cystic fibrosis (CF). It is evident that an anti-inflammatory therapy represents an important step in the treatment of CF patients. Corticosteroids and ibuprofen have been proven to slow down the impairment of the pulmonary function in CF patients but their use is limited by the frequency of adverse events. A novel strategy for delivering low doses of steroids for long periods through the infusion of autologous erythrocytes loaded with dexamethasone has been recently set up. A recent study suggested the feasibility of therapy with low doses of corticosteroids delivered through engineered erythrocytes in CF patients. This study presents a further analysis of safety and efficacy of this therapy. METHODS: The treatment group was not randomised and the assignment was based on the patient's consent. Patients entered the study if they had a forced expiratory volume in 1 second (FEV1) <70%, puberty development completed, pancreatic insufficiency, and chronic pulmonary infection requiring frequent cycles of intravenous antibiotic therapy. Patients were excluded if they underwent systemic corticosteriod therapy in the three months preceding the experimental treatment or were on therapy with non-steroidal anti inflammatory drugs (NASDs), or if they had liver CF disease, allergic bronchopulmonary aspergillosis, or positive tuberculin test. Controls were patients who followed a standard treatment, who fulfilled the enrollment criteria, and who were matched to the experimental group by gender, age, and severity of the disease. RESULTS: Nine patients in the experimental group received the treatment once a month for a period of 24 month. Patients did not develop diabetes, cataract, or hypertension, or other typical side effects of steroid treatment during the follow up period. There was a constant improvement of FEV1 in patients undergoing the experimental treatment compared to a gradual decrease of the same parameter in the standard therapy group (P = 0.04). The average of clinic and radiological indexes did not vary. The number of infective relapses that have required antibiotic intravenous therapy was not different in the two groups, although the average of these episodes was slightly higher in the experimental therapy group. CONCLUSION: Intraerythrocyte corticosteroid treatment may stabilize the respiratory function in CF patients but is often considered too invasive by patients. The results obtained by our study may help planning an experimental, controlled, randomised study. A sample size of 150 patients per group would be sufficient for demonstrating such a difference with a 95% confidence interval and a power of 90%.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS): impact of the inter-stages course on morbi-mortality and implications for management.

BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) was recently developed to induce rapid hypertrophy and reduce post-hepatectomy liver failure in patients with insufficient remnant liver volume (RLV). However, mortality rates >12% have been reported. This study aimed to analyze the perioperative course of ALPPS and to identify factors associated with morbi-mortality. METHODS: Between April 2011 and September 2013, 62 patients operated in 9 Franco-Belgian hepatobiliary centres underwent ALPPS for colorectal metastases (N = 50) or primary tumors, following chemotherapy (N = 50) and/or portal vein embolization (PVE; N = 9). RESULTS: Most patients had right (N = 31) or right extended hepatectomy (N = 25) (median RLV/body weight ratio of 0.54% [0.21-0.77%]). RLV increased by 48.6% [-15.3 to 192%] 7.8 ± 4.5 days after stage1, but the hypertrophy decelerated beyond 7 days. Stage2 was cancelled in 3 patients (4.8%) for insufficient hypertrophy, portal vein thrombosis or death and delayed to ≥9 days in 32 (54.2%). Overall, 25 patients (40.3%) had major complication(s) and 8 (12.9%) died. Fourteen patients (22.6%) had post-stage1 complication of whom 5 (35.7%) died after stage2. Factors associated with major morbi-mortality were obesity, post-stage1 biliary fistula or ascites, and infected and/or bilious peritoneal fluid at stage2. The latter was the only predictor of Clavien ≥3 by multivariate analysis (OR: 4.9; 95% CI: 1.227-19.97; p = 0.025). PVE did not impact the morbi-mortality rates but prevented major cytolysis that was associated with poor outcome. CONCLUSIONS: The inter-stages course was crucial in determining ALPPS outcome. The factors of high morbi-mortality rates associated with ALPPS are linked to the technique complexity.

Resting energy expenditure in young patients with cystic fibrosis receiving antibiotic therapy for acute respiratory exacerbations.

BACKGROUND: patients with cystic fibrosis commonly have severe malnutrition and growth retardation. Among possible causes of these manifestations are low caloric intake, loss of nutrients and increased resting energy expenditure. This study was designed to assess the influence of antibiotic therapy for infectious exacerbations on resting energy expenditure in young patients with cystic fibrosis. METHODS: We studied 17 patients with cystic fibrosis (mean age, 13.6 years). All were hospitalized to receive intravenous antibiotic therapy (mean duration, 2 weeks) for acute respiratory exacerbations. At the beginning of therapy and after it ended, all patients underwent blood chemical tests, anthropometrical measures, determination of body composition by bioelectrical impedance, spirometry, and indirect calorimetry. RESULTS: Antibiotic therapy led to a significant improvement in biochemical, spirometric variables and in estimated calorimetry measurements expressed in relation to fat-free mass. These findings suggest that infective exacerbations are among the causes of increased resting energy expenditure in young patients with cystic fibrosis. CONCLUSIONS: Indirect calorimetry may prove useful in the diagnosis of infective exacerbations and in monitoring the effect of antibiotic therapy in patients with cystic fibrosis.
