Home parenteral nutrition improves quality of life and nutritional status in patients with cancer: a French observational multicentre study.

PURPOSE: Malnutrition is a predictor of poor outcomes in patients with cancer. Little is known about the benefit of nutritional support in these patients. The purpose of this study was to assess the impact of home parenteral nutrition (HPN) on quality of life (Qol) in cancer patients. METHODS: We performed an observational prospective study to determine the impact of HPN on Qol in a population of patients with heterogeneous cancer. Physicians, patients and family members had to complete a questionnaire before HPN administration and 28 days after the course of HPN. Qol was evaluated using the self-administered questionnaire FACT-G. RESULTS: We included 767 patients with cancer of whom 437 ended the study. Mean patient age was 63±11.4 years and 60.5% were men. Primary gastrointestinal cancer was reported in 50% of patients and 65.3% were presenting metastases. Malnutrition was reported in 98.3%. After 28 days of HPN intake, significant improvement was observed in the Qol (49.95±5.82 vs. 48.35±5.01 at baseline, p<0.0001). The mean weight, serum albumin and the nutrition risk index had also improved significantly. Most patients (78%) had perceived a positive impact of the HPN. A significant improvement in patient's well-being was perceived also by family members and physicians. CONCLUSIONS: Our data suggest that preventing and correcting malnutrition using HPN in patients with cancer might have a significant benefit on their well-being. Randomized controlled studies are required to confirm this finding.

Fibrosis progression occurs in a subgroup of heavy drinkers with typical histological features.

BACKGROUND: Studies using consecutive liver biopsies constitute an attractive approach to gaining insight into the pathogenesis of alcoholic liver disease. AIM: To analyse histological factors at baseline, which are predictive of fibrosis progression and recurrence of alcoholic hepatitis. RESULTS: A total of 193 drinkers underwent consecutive biopsies at an interval of 4 years. At baseline, 20 had normal livers, 135 steatosis, five fibrosis and 33 alcoholic hepatitis. The fibrosis score increased from 1.07 +/- 0.07 to 1.7 +/- 0.94 (P < 0.001). In multivariate analysis, only steatosis (P = 0.04), alcoholic hepatitis (P = 0.0004) and stage of fibrosis (P < 0.0001) were independent predictive factors of the fibrosis score at the second biopsy. Cirrhosis developed more frequently in patients with steatosis (11%) and alcoholic hepatitis (39%) than in others (0%, P < 0.0001). Alcoholic hepatitis recurred more frequently in patients with alcoholic hepatitis at baseline: 58% vs. 15%, P < 0.0001. In multivariate analysis, alcoholic hepatitis at the first biopsy was the only predictive factor of its recurrence (P < 0.0001). CONCLUSIONS: In a large cohort of drinkers with consecutive biopsies, steatosis, fibrosis stage and alcoholic hepatitis at baseline were independent predictive factors of fibrosis progression. In terms of mechanisms, we propose a novel concept of multiple hits of alcoholic hepatitis occurring in the same patient.

Excessive alcohol consumption favours high risk polyp or colorectal cancer occurrence among patients with adenomas: a case control study.

BACKGROUND AND AIMS: Excessive alcohol consumption is a risk factor for developing colorectal adenomas. This study aimed to investigate the influence of excessive alcohol consumption on the occurrence of high risk polyps (adenoma > or = 10 mm, villous component, high grade dysplasia) or colorectal cancer among patients with at least one colonic adenoma. PATIENTS AND METHODS: Three groups of patients with at least one colorectal adenoma were included in a case control study: 401 heavy drinkers (group HD, mean daily alcohol intake 117 (SD 4) g/day for a mean duration of 22 (SD 0.6) years), aged 57 (0.5) years (78% men); 152 patients suffering from irritable bowel syndrome (IBS), aged 61 (0.9) years (57% male); and 108 patients with a family history (FH) of colorectal adenoma or cancer, aged 55 (1) years (64% male). Exclusion criteria were: anaemia, haematochezia, personal history of colorectal adenoma or cancer, and for groups HD and IBS a family history of colorectal adenoma and/or cancer. Relative risks were estimated by the odds ratio (OR) using a logistic regression model and were expressed with 95% confidence interval (CI). RESULTS: After age and sex adjustment, the likelihood of having an adenoma > or = 10 mm was higher in group HD than in the IBS group (OR 1.8, 95% CI (1.2-2.7)) and the likelihood of having high risk adenomas or cancer was higher in group HD compared with the IBS group (OR 1.6, 95% CI (1.2-2.1)) and the FH group although this was not significant (OR 1.6, 95% CI (0.97-2.6) (p=0.081); 90% CI (1.03-2.4)). After age and sex adjustment, the likelihood of having an adenoma with high grade dysplasia or cancer was higher in group HD than in the IBS group (OR 1.7, 95% CI (1.02-2.8)) or group FH, although this was not significant (OR 3.7, 95% CI (0.98-15) (p=0.076); 90% CI (1.10-12.47)). CONCLUSION: In patients with at least one colorectal adenoma, excessive alcohol consumption increases the likelihood of developing high risk adenomas or colorectal cancer.

[Ulceronecrotic tracheobronchial involvement in Crohn's disease]. / Atteinte trachéo-bronchique ulcéro-nécrotique au cours d'une maladie de Crohn.

We report the case of a young female patient hospitalized for the first episode of a colonic Crohn's disease with specific ulceronecrotic tracheobronchial involvement leading to chronic and invalidant cough. Symptomatic bronchopulmonary manifestations are very rare in the course of inflammatory bowel diseases and usually not mentioned in Gastroenterology textbooks.

Abnormal von Willebrand factor in bleeding angiodysplasias of the digestive tract.

BACKGROUND & AIMS: Involvement of an abnormal von Willebrand factor in the bleeding expression of gastrointestinal angiodysplasias has been suggested but not assessed by prospective studies. METHODS: To address this issue, 27 patients with either nonbleeding (group A, n = 9) or bleeding (group B, n = 9) digestive angiodysplasias or telangiectasias or diverticular hemorrhage (group C, n = 9) were enrolled. In all patients, an analysis of von Willebrand factor and a screening for the most common disorders associated with an acquired von Willebrand disease were performed. RESULTS: In all patients from groups A and C, von Willebrand factor was normal, and no underlying disease could be found. In contrast, all but 1 patient from group B had a variable selective loss of the largest multimeric forms of von Willebrand factor, associated in 7 cases with a stenosis of the aortic valve. CONCLUSIONS: This study indicates that most patients with bleeding angiodysplasia or telangiectasia have a deficiency of the largest multimers of von Willebrand factor induced by a latent acquired von Willebrand disease. Because these multimers are the most effective in promoting primary hemostasis at the very high shear conditions related to these vascular malformations, we suggest that their deficiency is likely to contribute to the bleeding diathesis.

[Regenerative nodular hyperplasia: variable clinical aspects]. / Hyperplasie nodulaire régénérative: des aspects cliniques très variables.

BACKGROUND: Regenerative nodular hyperplasia can take on very misleading aspects making diagnosis difficult. CASE REPORTS: We report three cases of regenerative nodular hyperplasia (RNH). In the first patient rupture of esophageal varices was associated with myelofibrosis. In the second, extensive portal thrombus formation was associated with consumption coagulopathy and essential thrombocytemia. The third patient had systemic sclerodermia, hepatic macronodules, refractory exsudative ascitis and chronic hepatic encephalopathy following surgery for a porto-cava anastomosis. DISCUSSION: The diagnosis of RNH should be suspected in a variety of clinical situations with search for associated diseases in all cases. The prognosis is related to the consequences of portal hypertension and the severity of the associated diseases.

Tumor necrosis factor soluble receptor p55 and lipid peroxidation in patients with acute alcoholic hepatitis.

OBJECTIVES: In experimental models, liver injury induced by ethanol, cytotoxic activity of tumor necrosis factor (TNF) -alpha is principally mediated by TNF receptor p55 (TNFRp55). Among the various mechanisms underlying the toxic effects of TNF-alpha, overproduction of reactive oxygen species seems to play a key role in mediating TNF-alpha-induced cytotoxicity. The aim of this study was to evaluate, in patients with alcoholic liver disease, whether alcohol TNFRp55-mediated hepatotoxicity could account for lipid peroxidation expressed by significant increase in serum thiobarbituric reactive acid substances (TBARS) content, and could be amplified by decrease in blood total glutathione content and decrease in plasma antioxidant protective capacity. METHODS: We studied 27 patients with histological alcoholic liver disease (five fibrosis, six acute alcoholic hepatitis (AAH) without cirrhosis, four cirrhosis without AAH, and 12 cirrhosis with AAH. TNFsRp55 and TNFsRp75 plasma levels were measured using ELISA assays. Plasma lipid peroxidation was evaluated by the content of TBARS. Total glutathione (tGSH) content in blood was determined by a kinetic assay. The sensitivity of erythrocytes to an oxidative stress and the plasma antioxidant protective capacity were simultaneously determined by a simple method. RESULTS: In the 18 patients with mild or severe AAH, the plasma levels of TNFsRp55 were negatively correlated with tGSH and were positively correlated with TBARS, with total bilirubin and with discriminant function. tGSH was positively correlated with plasma selenium. The plasma levels of TNFsRp75 were positively correlated with TBARS and with total bilirubin. There was no significant correlation with the mean inhibitory 50% plasma volume or with the percentage of hemolyzed erythrocytes. CONCLUSIONS: Our data support the notions that, in patients with AAH, TNFsRp55 probably mediates cytotoxicity of TNF-alpha, and that cytotoxic effect could be amplified by tGSH depletion in enhancing lipid peroxidation.

Pancreatic involvement in von Hippel-Lindau disease. The Groupe Francophone d'Etude de la Maladie de von Hippel-Lindau.

BACKGROUND & AIMS: Pancreatic involvement in von Hippel-Lindau (VHL) disease, a genetic disorder with a dominant mode of inheritance affecting various organs, has rarely been studied. We assessed the prevalence, type of lesions, natural history, and impact of pancreatic involvement in patients with VHL. METHODS: A total of 158 consecutive patients from 94 families with VHL disease were studied in a prospective French collaborative study. All patients underwent systematic screening for VHL lesions, including computerized tomography (CT) scanning of the pancreas reviewed by an experienced radiologist. Clinical data, investigations, and treatments performed were also reviewed. RESULTS: Pancreatic involvement was observed in 122 patients (77.2%) and included true cysts (91.1%), serous cystadenomas (12.3%), neuroendocrine tumors (12.3%), or combined lesions (11.5%). The pancreas was the only organ affected in 7.6% of patients. Patients with pancreatic lesions had fewer pheochromocytomas than those without (14/122 vs. 16/36; P<0.0001), and patients with neuroendocrine pancreatic tumors had renal involvement less often than those without (8/99 vs. 6/20; P = 0.013). None of the patients with neuroendocrine tumors had symptoms of hormonal hypersecretion. Pancreatic lesions evolved in half of patients but required specific treatment in only 10 (8.2%) when they were symptomatic or for the resection of large neuroendocrine tumors. CONCLUSIONS: Pancreatic involvement is seen in most patients with VHL disease. Although symptoms are rare, specific treatment of pancreatic lesions is required in selected patients, mainly those with neuroendocrine tumors.

[Abdominal tuberculosis: deceptive and still encountered]. / La tuberculose abdominale: trompeuse et toujours d'actualité.

BACKGROUND: Extrapulmonary manifestations of tuberculosis are increasing in incidence. Abdominal tuberculosis may mimic a variety of gastrointestinal disorders. The diagnosis of abdominal tuberculosis is still difficult to establish before surgery. CASE REPORTS: We report 3 cases of abdominal tuberculosis in immunocompetent individuals. One patient presented with an ileocecal mass mimicking cancer. The second one presented with fever, ileocecal mass and ascites leading to the diagnosis of appendiceal peritonitis. The last patient was admitted for ascites, ovarian mass and high CA 125 serum level simulating ovarian cancer with peritoneal carcinomatosis. COMMENTS: In cases of abdominal tuberculosis when standard investigations are unhelpful, a PCR should be performed. Estimation of adenosine deaminase in ascitic fluid is an easy and reliable method for diagnosing tuberculous ascites. With these non invasive diagnostic procedures, surgery should be reserved only to patients with complications.

[Biological diagnosis of the type of liver disease in alcoholic patients with abnormal liver function tests]. / Diagnostic biologique du type d'hépatopathie chez des malades alcooliques ayant des tests biologiques hépatiques anormaux.

OBJECTIVES: The histological diagnosis of the different stages of alcoholic liver disease is not systematic. The aim of this study was to assess whether common biological features were useful in identifying the different stages. METHODS: One thousand twenty six alcoholic patients with liver histology and without any associated diseases or infections likely to alter serum liver tests were studied. Diagnostic analyses were performed using stepwise discriminant analysis in the entire population and in asymptomatic patients. RESULTS: a) Serum ASAT activity levels were only normal in 39% of the patients with normal histological liver and in 14% of the patients with steatosis; b) liver failure was already present in patients with fibrosis without cirrhosis; c) betagamma block was the only biochemical parameter which confirmed the diagnosis of cirrhosis without biopsy; d) the diagnostic accuracy of common tests was weak for the diagnosis of alcoholic liver disease without cirrhosis but prothrombin time could be useful in excluding the diagnosis of cirrhosis with and without acute alcoholic hepatitis when liver biopsy is not available. CONCLUSION: Only a prothrombin time of 80% with a negative predictive value of 94% and the presence of beta-gamma [corrected] block with a positive predictive value of 98% were useful for assessing the diagnosis of cirrhosis in all patients with alcoholic liver disease.

A particularly aggressive combined glucagonoma and gastrinoma syndrome.

Duodeno-pancreatic biochemically polyfunctional endocrine tumour is a well known entity. Usually, only one hormone is responsible for the clinical features. We report a case of aggressive combined glucagonoma and gastrinoma tumour without metastases, causing respectively diabetic ketoacidosis and fulminant peptic ulcer, and death. Occasional patients can present with clinical features of both glucagonoma and gastrinoma. Diabetic patients exhibiting migratory skin lesions should be suspected of glucagonoma. In addition, a multidisciplinary approach to such patients including dermatologists, surgeons, radiologists and endoscopists is mandatory.

Plasma levels of soluble tumor necrosis factor receptors p55 and p75 in patients with alcoholic liver disease of increasing severity.

BACKGROUND/AIMS: Correlations between serum levels of soluble tumor necrosis factor receptors p55 (TNFsRp55) and Child Pugh index have previously been reported in alcoholic patients with cirrhosis. We have undertaken this study to improve understanding of the role of tumor necrosis factor soluble receptors (TNFsRs) in alcoholic liver disease. METHODS: One hundred and two patients with alcoholic liver disease of various severity (23 pure steatosis, 22 fibrosis, seven acute alcoholic hepatitis without cirrhosis, 12 cirrhosis without acute alcoholic hepatitis, 14 cirrhosis with mild acute alcoholic hepatitis and 24 cirrhosis with severe acute alcoholic hepatitis) were studied. Blood was collected on EDTA and plasma was tested for TNFsR concentrations using ELISA assays. RESULTS: Plasma levels of TNFsRp55 and p75 increased progressively with the severity of liver disease, reaching a maximum in cirrhotic patients with severe acute alcoholic hepatitis. Plasma levels of TNFsRp55 in patients with fibrosis and of TNFsRp75 in patients with acute alcoholic hepatitis without cirrhosis were already higher than in healthy controls. In cirrhotic patients with or without acute alcoholic hepatitis TNFsRp55 and p75 were significantly increased compared with controls. In cirrhotic patients, plasma levels of TNFsRp55 correlated positively with all parameters of liver injury, whereas the TNFsRp75/ TNFsRp55 ratio correlated negatively. In cirrhotic patients with severe acute alcoholic hepatitis, the TNFsRp75/TNFsRp55 ratio was significantly lower than in all other groups. In cirrhotic patients with severe acute alcoholic hepatitis treated by prednisolone, the decrease in TNFsRp55 plasma levels between day 1 and day 15 was significantly more important in patients still alive at 2 months than in patients who died within 2 months. CONCLUSIONS: These results show that the expression of TNF-soluble receptors (TNFsRs) participates in the early phases of the alcoholic liver disease and that the TNFsRp75/TNFsRp55 ratio and plasma levels of TNFsRp55 may help to determine the diagnosis and the prognosis of severe acute alcoholic hepatitis in cirrhotics.

Post-traumatic membranous obstruction of the inferior vena cava associated with a hypercoagulable state.

It has been hypothesized that abdominal trauma may be one of the factors involved in membranous obstruction of the inferior vena cava. We present two cases of membranous obstruction of the inferior vena cava associated with trauma. One asymptomatic case, associated with an occult myeloproliferative disorder, developed within 3 years of a violent abdominal trauma. The other case, associated with familial plasminogen deficiency, was discovered at surgery 3 days after a road accident with obvious abdominal trauma, since superimposed extensive thrombosis of the inferior vena cava caused acute Budd-Chiari syndrome. We conclude that underlying prothrombotic conditions are probably necessary for the development of membranous obstruction of the inferior vena cava and that minor trauma may contribute to the development of thrombosis through indirect mechanisms.

[Predictive risk factors for progression to cirrhosis in early stage alcoholic liver disease]. / Facteurs prédictifs d'évolution vers la cirrhose à un stade précoce de la maladie alcoolique du foie.

OBJECTIVE: To assess the risk factors of cirrhosis in early stage alcoholic liver disease. PATIENTS: We investigated 83 heavy drinkers (60 males and 23 females) in whom the first of two liver biopsies showed normal or pure alcoholic fatty liver. RESULTS: When the six following variables: sex, age, delay between the first and last biopsy, total duration of alcohol consumption before the first biopsy, daily alcohol consumption for the last 5 years before the first biopsy and the extent of fatty liver in the first biopsy, were considered together in stepwise regression analysis, the delay between the first and last biopsy (p < 0.0001), sex (P < 0.004) and the extent of fatty liver in the first biopsy (P < 0.06) significantly improved the prediction of cirrhosis. The odds ratio of cirrhosis for a women was 19.1 (confidence interval 95% [1.85-197]). The odds ratio for cirrhosis for a percentage of fatty liver > or = 5/10 was 7.4 (confidence interval 95% [1-92]). CONCLUSION: With the same delay between two liver biopsies, the female sex and the extent of fatty liver are two independent risk factors for the development of cirrhosis in heavy drinkers.

Blindness in different types of eye disease. A study based on the records of the Department of Eye Diseases in the Medical University, Plovdiv for the period 1982-1991.

Between 1982 and 1991, inclusive, a total of 13718 patients were treated in the Department of Eye Diseases in Plovdiv University of Medicine. Cataract patients formed the most numerous group (19.71%), followed by those with diseases of the retina (9.53%), glaucoma (7.95%), uveitis (4.9%), diseases of the cornea (3.86%), malignant tumors of the eyelids and the eyeball (2.29%) and diseases of the optic nerve (1.54%). Of these 13718 patients, 1727 (12.58%) had monocular and binocular vision below 0.08. The patients with visual acuity from 0 to 0.03 were 1330 (9.69%). Nosologically, they were distributed as follows: glacoma-422 (3.07%), eye traumas-281 (2.04%), diseases of the retina-270 (1.96%), diseases of the cornea-89 (0.64%), cataract-80 (0.58%), uveitis-77 (0.56%), malignant tumors of the eyelids and the eyeball-66 (0.48%), and diseases of the optic nerve-45 (0.32%). Glaucoma was found to be the most common cause of blindness among the patients treated in the Department of Eye Diseases, followed by eye traumas and disease of the retina. The importance of the vascular factor in inducing blindness is undeniably great. It is the underlying cause of the open-angle glaucoma, the diseases of the retina and the optic nerve.

Cardioskeletal mitochondrial myopathy associated with chronic magnesium deficiency.

A 3-year-old boy presenting with convulsions and carpopedal spasm had hypomagnesemia and hypermagnesuria due to congenital magnesium-losing nephropathy. Despite chronic oral and intermittent intravenous magnesium supplementation, he remained chronically hypomagnesemic. At age 4, he developed a progressive proximal myopathy and dilated hypertrophic cardiomyopathy that ultimately contributed to his death at age 14 years. Skeletal and cardiac muscle specimens showed a mitochondrial myopathy with increased numbers of enlarged, structurally abnormal mitochondria. Muscle magnesium content was markedly decreased. Chronic oral and intermittent intravenous magnesium supplementation may be inadequate to prevent the progressive cardioskeletal myopathy associated with the chronic magnesium deficiency of congenital magnesium-losing nephropathy.

Churg-Strauss syndrome. Development of cardiomyopathy during corticosteroid treatment.

A patient with Churg-Strauss syndrome had pulmonary lesions, vasculitis, gastrointestinal tract involvement, and leukocytosis with hypereosinophilia. A wedge section from the lung showed necrotizing granulomata filled with necrotic eosinophils and fibrinoid, and rimmed by giant cells and eosinophils. Arteries and veins of all sizes were affected with perivascular eosinophilic-rich, palisaded, giant cell granulomata with evidence of partial or complete occlusion. The patient was treated with prednisone, with excellent resolution of his symptoms. Recurrent episodes of pneumonia and wheezing responded to increased levels of prednisone plus bronchodilators and antibiotics. Cardiomyopathy developed after two years while taking prednisone. His condition has been managed with digoxin, diuretics, and increased amount of prednisone. Although our patient has shown clinical improvement in his cardiac status, objective studies show minimal resolution.
