Gender-related differences in patients with carcinoid syndrome: new insights from an Italian multicenter cohort study.

BACKGROUND: The incidence of neuroendocrine neoplasm (NEN) and related carcinoid syndrome (CaS) has increased markedly in recent decades, and women appear to be more at risk than men. As per other tumors, gender may be relevant in influencing the clinical and prognostic characteristics of NEN-associated CS. However, specific data on carcinoid syndrome (CaS) are still lacking. PURPOSE: To evaluate gender differences in clinical presentation and outcome of CaS. METHODS: Retrospective analysis of 144 CaS patients from 20 Italian high-volume centers was conducted. Clinical presentation, tumor characteristics, therapies, and outcomes (progression-free survival, PFS, overall survival, OS) were correlated to gender. RESULTS: Ninety (62.5%) CaS patients were male. There was no gender difference in the site of primary tumor, tumor grade and clinical stage, as well as in treatments. Men were more frequently smokers (37.2%) and alcohol drinkers (17.8%) than women (9.5%, p = 0.002, and 3.7%, p = 0.004, respectively). Concerning clinical presentation, women showed higher median number of symptoms (p = 0.0007), more frequent abdominal pain, tachycardia, and psychiatric disorders than men (53.3% vs 70.4%, p = 0.044; 6.7% vs 31.5%, p = 0.001; 50.9% vs. 26.7%, p = 0.003, respectively). Lymph node metastases at diagnosis were more frequent in men than in women (80% vs 64.8%; p = 0.04), but no differences in terms of PFS (p = 0.51) and OS (p = 0.64) were found between gender. CONCLUSIONS: In this Italian cohort, CaS was slightly more frequent in males than females. Gender-related differences emerged in the clinical presentation of CaS, as well as gender-specific risk factors for CaS development. A gender-driven clinical management of these patients should be advisable.

Hypersensitivity to platinum salts according to BRCA status in ovarian cancer: A retrospective analysis of clinical outcomes and systematic review of literature.

BACKGROUND: Hypersensitivity reactions (HSRs) to platinum are an important issue in the treatment of patients (pts) with ovarian cancer (OC). Germline BRCA mutations have been proposed as a risk factor. We aimed at evaluating the incidence and severity of HSRs to platinum in OC pts. with known BRCA status. PATIENTS AND METHODS: We retrospectively analyzed 432 pts. from 5 Italian Centers. In addition, we performed a systematic review and meta-analysis of published series. RESULTS: Four hundred nine pts. received at least one prior platinum-based treatment line: 314 were BRCA wild type (77%) and 95 were BRCA mutated (23%). There was no statistical difference in exposure to platinum. Incidence of any grade HSRs was higher among BRCA mutated pts. [9% vs 18%, p = 0.019] and the time-to-HSRs curves show that the risk increases with the duration of platinum exposure, in BRCA mutated pts. more than in BRCA wild type. A multivariable analysis showed that harboring a germline BRCA mutation was related to a higher incidence of HSRs (HR: 1.84, 95% CI 1.00-3.99, p = 0.05) while having received pegylated liposomal doxorubicin (PLD) was related to a lower incidence of HSRs (HR: 0.03 95% CI 0.004-0.22, p = 0.001). The systematic review confirmed the higher incidence of HSRs in BRCA mutated pts., though heterogeneity among series was significant. CONCLUSIONS: In OC pts. with BRCA mutations, there is a significantly higher incidence of HSRs to carboplatin, not justified by longer drug exposure. On the other hand, PLD exerted a protective role in our series.

Accuracy of CT and MRI to assess resection margins in primary malignant bone tumours having histology as the reference standard.

AIM: To evaluate the accuracy of magnetic resonance imaging (MRI) and computed tomography (CT) in assessing the resection margins of primary malignant bone tumours. MATERIALS AND METHODS: Resected primary malignant bone tumour specimens removed from 46 patients (27 male; mean age: 48±22 years) were imaged using MRI (fat-saturated proton density-weighted and three-dimensional fat-suppressed T1-weighted gradient-recalled-echo) and CT immediately after surgery. A radiologist and an orthopaedist evaluated bone and soft-tissue margins of the specimens on both examinations. Histological evaluation was performed by a senior orthopaedic oncology pathologist. Margins were classified as R0 (safe margins), R1 (residuals between 0 and 1 mm), and R2 (macroscopic residuals). Cohen's k, chi-square, and McNemar's statistics were used. RESULTS: Having histology as the reference standard, reproducibility of the radiologist ranged from moderate (k=0.544) to substantial (k=0.741) for bone and soft-tissue margins on CT, respectively, while that of the orthopaedist ranged from fair (k=0.316) to moderate (k=0.548). When comparing R2 and R0+R1 scores, reproducibility of readers' evaluation of bone margins increased ranging from substantial (k=0.655) to perfect (k=1.000). Inter-reader agreement ranged from fair (k=0.308) to substantial (k=0.633). Accuracy of the radiologist and orthopaedist ranged from 76% to 83% and from 68% to 72%, respectively. When comparing R2 and R0+R1 scores, the accuracy of both readers ranged from 83% to 100%. There was no association between local recurrence and margin scores of histology, MRI, and CT (p≥0.058). CONCLUSIONS: MRI and CT may be useful for extemporaneous analysis of resection margins of primary malignant bone tumours, although wide accuracy variability between the different imaging methods was observed.

Epidemiological and clinical features of HEV infection: a survey in the district of Foggia (Apulia, Southern Italy).

In this study we assessed the seroprevalence of hepatitis E virus (HEV) infection in both the Italian population and immigrants from developing countries in Foggia (Apulia, Southern Italy). The seroprevalence of HEV was determined in 1217 subjects [412 (34%) immigrants and 805 Italian subjects (blood donors, general population, HIV-positive, haemodialysis patients)]. Serum samples were tested for anti-HEV and confirmed by Western blot assay; in positive patients HEV RNA and genotype were also determined. There were 8·8% of patients that were positive to anti-HEV, confirmed by Western blot. The prevalence in immigrants was 19·7%, and in Italians 3·9% (blood donors 1·3%, general population 2·7%, HIV-positive patients 2·0%, haemodialysis patients 9·6%). Anti-HEV IgM was found in 38/107 (35·5%) of the anti-HEV-positive serum samples (34 immigrants, four Italians). This study indicates a higher circulation of HEV in immigrants and Italian haemodialysis patients, whereas a low prevalence of HEV antibodies was seen in the remaining Italian population.

Lynch syndrome-associated endometrial cancer patient with a rare novel germline likely pathogenic variant of MSH2 gene: A case report.

The Lynch syndrome (LS) is an autosomal dominant condition usually characterized by germline pathogenic variants in DNA mismatch repair (MMR) genes. Despite the guidelines now available, determining the pathogenicity of rare variants remains challenging, as the clinical significance of a genetic variant could be uncertain, but it may represent a disease-associated variation in the aforementioned genes. In this case report we will describe the case of a 47 years-old female affected by endometrial cancer (EC) with an extremely rare germline heterozygous variant in the MSH2 gene (c.562G > T p. (Glu188Ter), exon 3) that is likely pathogenic, and a family history consistent with LS.

Immigration and hepatitis B virus: epidemiological, clinical and therapeutic aspects.

This study in Italy aimed to evaluate the epidemiological, clinical and therapeutic aspects of hepatitis B virus (HBV) infection in a population of recent (< 6 months) immigrants. Between February 2003 and December 2004, 83 (9.3%) out of 890 immigrants tested positive for hepatitis B surface antigen. All were men and 62.6% came-from Africa, 21.6% from Asia and 16.8% from Eastern Europe. About half (54.3%) of the patients had elevated alanine aminotransferase levels and detectable serum HBV DNA. Genotype distribution was as follows: E (20 cases), D (14 cases) and A (11 cases). Our study underscores the potential of migratory flow to introduce genotype non-D hepatitis B virus into our country.

HIV-1 biological phenotype and predicted coreceptor usage based on V3 loop sequence in paired PBMC and plasma samples.

Paired PBMCs and plasma samples from 34 HIV-infected patients were studied to verify the relationship between coreceptor use based on genotyping of V3 region of HIV-1 envelope gp120 and biological phenotype with virus isolation and subsequent correlation to clinical characteristics. The "11/25" rule, geno2pheno and PSSM were compared. All SI patients were HIV-1 subtype B (p=0.04) and had a lower CD4 count than NSI patients (p=0.01), while no differences were observed in mean HIV-RNA (log) (p=0.6). SI phenotype was not associated with AIDS-defining events (p=0.1) or with concurrent antiretroviral therapy (p=0.4). With geno2pheno, which shows the highest sensibility (83%), an X4 or X4/R5 genotype in PBMC DNA was also associated to B-subtype and lower CD4 count (p=0.01) compared to R5 isolates. Based on plasma RNA sequences, the predicted coreceptor usage agreed with PBMC DNA in 79% of cases with the "11/25" rule, 82% with geno2pheno, and 82% with PSSM. A X4 virus in plasma (but not in PBMCs) was significantly associated with HAART in all three methods (p=0.01 for "11/25" rule, p=0.01 for geno2pheno and p=0.03 for PSSM). Due to viral mixtures and/or difficulties in genotype interpretation, current V3 sequence-based methods cannot accurately predict HIV-1 coreceptor use.

Risk factors and outcome among a large patient cohort with community-acquired acute hepatitis C in Italy.

BACKGROUND: The epidemiology of acute hepatitis C has changed during the past decade in Western countries. Acute HCV infection has a high rate of chronicity, but it is unclear when patients with acute infection should be treated. METHODS: To evaluate current sources of hepatitis C virus (HCV) transmission in Italy and to assess the rate of and factors associated with chronic infection, we enrolled 214 consecutive patients with newly acquired hepatitis C during 1999-2004. The patients were from 12 health care centers throughout the country, and they were followed up for a mean (+/- SD) period of 14+/-15.8 months. Biochemical liver tests were performed, and HCV RNA levels were monitored. RESULTS: A total of 146 patients (68%) had symptomatic disease. The most common risk factors for acquiring hepatitis C that were reported were intravenous drug use and medical procedures. The proportion of subjects with spontaneous resolution of infection was 36%. The average timespan from disease onset to HCV RNA clearance was 71 days (range, 27-173 days). In fact, 58 (80%) of 73 patients with self-limiting hepatitis experienced HCV RNA clearance within 3 months of disease onset. Multiple logistic regression analyses showed that none of the variables considered (including asymptomatic disease) were associated with increased risk of developing chronic hepatitis C. CONCLUSIONS: These findings underscore the importance of medical procedures as risk factors in the current spread of HCV infection in Italy. Because nearly all patients with acute, self-limiting hepatitis C--both symptomatic and asymptomatic--have spontaneous viral clearance within 3 months of disease onset, it seems reasonable to start treatment after this time period ends to avoid costly and useless treatment.

Extended lamivudine treatment in patients affected by chronic active anti-Hbe positive hepatitis.

The aim of the study was to evaluate the biochemical and virological response and the histological changes in 34 chronic hepatitis B anti-Hbe-positive patients treated with lamivudine at 100 mg/day orally for five years. Liver biopsies were performed in all patients at least 6 months before starting therapy and 3 months after the stop of treatment. After 12 months of therapy, 70.6% of patients showed evidence of HBV DNA clearance and normal ALT levels; 64.7% and 55.8% of patients maintained a complete response after two and three years of therapy, respectively, 47% after four years and 44.1% after five years. The histological activity index improved in 13%, remained unchanged in 61% and worsened in 26% of patients with tyrosine-methionine-aspartate-aspartate (YMDD) variants compared to 63, 27 and 0% without variants, respectively. The authors conclude that the clinical benefit of lamivudine is greatest for patients without YMDD variants after 5 years of extended treatment.

Access to HAART in HIV-infected immigrants: a retrospective multicenter Italian study.

Since 1996, AIDS has declined in the Italian population, but cases in foreign patients, including both recent immigrants and long-term residents, have increased from 3.9% in 1995-1996 to 15.4% in 2001-2002. This increase can only be partly explained by a higher migratory flow and might reflect a delayed access to health facilities and to antiretroviral therapy in migrants. We performed a survey for the year 2003 of HIV-infected immigrants to Italy from countries outside the European Union to verify which factors might influence a lack of access to highly active antiretroviral therapy (HAART). Italian centers of infectious diseases were requested to send sociodemographic and clinical data of HIV-infected immigrant patients. A total of 553 HIV-infected immigrants (49.9% women) were evaluated, representing 6.5% of all HIV-infected patients from these centers. The mean duration of residency in Italy was 6.6 +/- 5.0 years. The country of origin was Africa (64.5%), North and South America (24.2%), Eastern Europe (7.0%), and Asia (3.8%). A total of 407 of 553 patients (73.6%) were taking antiretroviral drugs at the time of screening. Females presented a younger age (p = 0.001), a lower frequency of Centers for Disease Control (CDC) stage B/C (p = 0.008) and a more frequent heterosexual exposure to HIV (p < 0.001), while no differences were observed for time of first positive serology (p = 0.7). CD4 cell count (p = 0.9) and log plasma HIV-RNA (p = 0.1). Characteristics of HAART patients were compared to those of nontreated patients, despite a CD4 cell count less than 350 cells/mm(3). No significant difference was found for gender, country of origin, risk factor, and years of Italian residence, while legal immigrants (p = 0.018) and registered in the National Health Service (p = 0.014) were significantly more likely to receive HAART compared to illegal immigrants.

Prevalence of HIV infections in hospitalised immigrants in Clinics of Infectious Diseases in Italy: a multicentric survey.

Our aim was to evaluate the prevalence of HIV infection in immigrants hospitalised in infectious disease settings in Italy during 2002. Each participating centre filled in a CRF which regarded the number of immigrants hospitalised in ordinary regime or in day-hospital during 2002 and, for HIV-positive patients only, some demographic (age, sex, origin) and clinical features (only HIV positivity or AIDS, new diagnosis or not, diagnosis of opportunistic infections). A total of 46 Infectious Diseases Units participated in the study and a total number of 2255 patients were tested for anti-HIV, irrespective of the cause of hospitalization, with 378 (16%) cases of positivity. Women accounted for 47.9%; the mean age of the population was 34.5 years. African patients showed a higher prevalence of HIV infections than subjects from other geographical areas (61.9% of all cases). Most HIV-infected patients were unaware of their positivity. In conclusion, HIV infection represents one of the main health problems among immigrants, particularly of African origin.

[Epidemiologic multicenter study of the prevalence of hepatitis in hospitalised immigrants in Italy in the year 2002]. / Studio epidemiologico multicentrico sulla prevalenza di epatiti virali in immigrati ospedalizzati in Italia nel 2002.

AIM: To retrospectively evaluate the prevalence of hepatitis in immigrant patients hospitalised in 48 Italian Operative Unit of Infectious Diseases during 2002. METHODS AND PATIENTS: in our study we included the clinical data of 2255 immigrated patients hospitalised, during the period between 01/01/2002-31/12/2002, in ordinary admission or in Day Hospital in Infectious Diseases O.U. and we have evaluated the prevalence of hepatitis in this population. RESULTS: 282 patients affected by hepatitis has been evidenced (12.5% of total hospitalised patients). The prevalent form was HBV-related (41.6% in chronic forms and 48.4% in acute), while the rate for HCV were less (37.5% in chronic and 3% in acute). The most part of patient were men (59.6%), with a mean age of 34.2 years and come from east-European countries (34.39%). CONCLUSION: Viral hepatitis are the third infectious diseases evidenced in immigrated population. HBV-chronic hepatitis is the prevalent form in immigrated patients, as expression of absence of vaccine prophylaxis in many countries. HCV-form was less frequent and it is particularly presents in east-European patients, probably as expression of endogenous drug abuse.

Interferon alpha-2B and ribavirin in combination for patients with chronic hepatitis C who failed to respond to, or relapsed after, interferon alpha therapy: a randomized trial.

PURPOSE: To assess the efficacy of interferon alpha-2b and ribavirin in combination in the treatment of patients with chronic hepatitis C who had either failed to respond to therapy with interferon alpha (nonresponders), or who had relapsed after interferon therapy (relapsers). SUBJECTS AND METHODS: Four hundred patients with chronic hepatitis C (200 nonresponders and 200 relapsers) were randomly assigned in equal numbers to receive either subcutaneous administration of recombinant interferon alpha-2b (3 million units three times per week) and ribavirin (1,000 to 1,200 mg/daily orally) or interferon alpha-2b alone (6 million units three times per week). Both ribavirin and interferon alpha-2b were given for 24 weeks. The patients were then followed for an additional 24 weeks. RESULTS: At the end of the treatment period, normalization of serum alanine aminotransferase levels and absence of hepatitis C virus RNA were seen in 21% of nonresponders and in 39% of relapsers who were treated with interferon alpha-2b and ribavirin, compared with 5% of nonresponders (P = 0.001) and 9% of relapsers treated with interferon alpha-2b alone (P <0.001). At the end of follow-up, 14% of nonresponders and 30% of relapsers treated with the combination therapy had a sustained response, compared with 1% of nonresponders (P = 0.001) and 5% of relapsers treated with interferon alpha alone (P <0.001). CONCLUSIONS: A 24-week course of treatment with interferon alpha-2b and ribavirin offers a chance of sustained response, whereas retreatment with interferon alpha-2b alone does not give satisfactory results. The role of long-term therapy in inducing prolonged remission remains to be explored.

Effects of some AMPA receptor antagonists on the development of tolerance in epilepsy-prone rats and in pentylenetetrazole kindled rats.

The non-selective alpha-amino-3-hydroxy-5-methyl-isoxazole-4-propionic acid (AMPA) receptor antagonists, 2,3-benzodiazepine derivatives CFM-1 (3,5-dihydro-7,8-dimethoxy-1-phenyl-4H-2,3-benzodiazepin-4-one) and CFM-2 (1-(4'-aminophenyl)-3,5-dihydro-7,8-dimethoxy-4H-2,3-benzodiazepin -4-one), following intraperitoneal (i.p.) administration, were studied against audiogenic seizures in genetically epilepsy-prone rats (GEPRs) or pentylenetetrazole induced kindling in rats. After acute i.p. administration the ED50 values of CFM-1 against the clonic and tonic phases of the audiogenic seizures 30 min after pretreatment were 40 (16-100) and 13 (8-25) micromol kg(-1), respectively. The animals used for chronic study were treated i.p. daily (at 10 h) for 4 weeks with CFM-1 (20 or 50 micromol kg(-1)). Chronic treatment for 2 weeks with CFM-1 gave ED50 values against clonic and tonic seizures of 39 (22-69) and 16 (8-25) micromol kg(-1), respectively, whereas chronic treatment for 4 weeks gave ED50 values against clonic and tonic seizures of 42 (18-98) and 17 (7-41.3) micromol kg(-1), respectively. The duration of anticonvulsant activity observed between 0.5 and 4 h following administration of CFM-1 was similar for acute and chronic treatment. Two groups of Sprague-Dawley rats received CMF (20 or 50 micromol kg(-1)) 30 min before a subconvulsant dose of pentylentetrazole (25 mg kg(-1) i.p.) which is able to increase seizure severity in control animals (i.e., chemical kindling). Pretreatment with CFM-2 delayed the progression of seizure rank during repeated administration of pentylentetrazole. At the end of the period of repeated pentylentetrazole treatment (6 weeks) the mean seizure score was 0 in vehicle treated controls, 4.3 in animals treated with vehicle + pentylentetrazole, 2.2 in rats treated chronically with CFM-2 (20 micromol kg(-1) i.p.) + pentylentetrazole and 1.0 in rats treated repeatedly with CFM-2 (50 micromol kg(-1) i.p.) + pentylenetetrazole. CFM-2 was also able to antagonize the long-term increase in sensitivity of the convulsant effects of GABA function inhibitors in pentylentetrazole-kindled animals. Thus, the administration of a challenge dose of pentylentetrazole (15 mg kg(-1) i.p.) or picrotoxin (1.5 mg kg(-1) i.p.) 15 or 30 days after the end of the repeated treatment showed that animals treated with CFM-2 were significantly protected against seizures induced by pentylentetrazole or picrotoxin. The data suggest that, following repeated treatment, tolerance to the novel AMPA receptor antagonists does not develop (CFM-1 in genetically epilepsy-prone rats and CFM-2 in the pentylentetrazole kindling model of epilepsy). Thirteen minutes after drug injection on days 1, 14 and 28 of chronic treatment the motor impairment induced by these compounds was studied with a rotarod apparatus. The TD50 values for CFM-1 or CFM-2-induced impairment of locomotor performance were similar following acute and repeated treatment. The data also suggest that some novel 2,3-benzodiazepines may have clinical potential for some types of epilepsy.

Association between HLA class II antigens and hepatitis C virus infection.

The aim was to confirm the influence of HLA Class II antigens on the progression of HCV infection and to assess the relationship between these antigens and histological damage, HCV viral load and HCV genotype. 143 patients were enrolled and divided into three groups. Group A included 34 anti-HCV positive, HCV-RNA negative patients with ALT persistently normal; group B included 39 patients with HCV-RNA positive and abnormal ALT level; group C included 70 normal subjects. Serological HCL typing was performed with lymphocytotoxicity test by Terasaky and McClelland, using lymphobeads HLC class II. The frequency of HLA DR11 (5) was significantly higher in the control group (52.9%) and in group A (64.7%), than in group B (28.2%). Allele HLA DR6 was demonstrated in a similar proportion (26%) among control group and group B, while HLA DR14 (6) was less frequent among controls (18% vs 1.4%). In group A the frequency of HLA DR14 (6) was 3% compared to group B, HLA DR17 (3) was prevalent (15.4%) in group B. Liver damage was associated with the detection of HLA DR14 (6) and HLD DR17 (3) antigens. Significantly lower levels of HCV-RNA were measured in subjects with HLA DR11 (5) than in these with either DR6 or DR17 (3). HLA class II antigens appear crucial for resolution or progression of HCV hepatitis. The punctual identification of these genetic factors may, therefore, prove to be useful in predicting disease evolution, in guiding the appropriate therapy for patients with poor prognosis, and in encouraging the development of now therapeutic strategies.

Behavioral effects resulting from sub-chronic treatment of rats with extract of fresh stabilized cola seeds.

The aim of our study was to compare the effects of a sub-chronic treatment with fresh cola seed extract and pure caffeine in the male rat. The activity tests (open-field) and reactivity (tail-tap, resistance to capture), show that fresh cola has an effect on behavior similar to that of caffeine. However, the effects of cola are more gradual than those of caffeine. Furthermore, cola administration leads to an increase in the fall latency observed during the grasping test. These results suggest that the fresh cola seed has both psychostimulating properties similar to those of caffeine, and an original effect on muscular tonus.

Anticonvulsant activity and plasma level of 2,3-benzodiazepin-4-ones (CFMs) in genetically epilepsy-prone rats.

Anticonvulsant properties of some 2,3-benzodiazepine derivatives acting as alpha-amino-3-hydroxy-5-methyl-isoxazole-4-propionic acid (AMPA) antagonists have been examined in vivo in the genetically epilepsy-prone rats using an audiogenic seizures assay. 2,3-Benzodiazepin-4-ones (CFMs) are nonselective AMPA antagonists that have been found to be potent anticonvulsant compound is in acute models of epilepsy. Because very little is known about their actions in a chronic model of epilepsy, and no correlations exist between anticonvulsant potency and plasma levels of these derivatives, we planned to investigate such a relationship. Maximal anticonvulsant protection occurred 15-60 min after the IP administration of GYKI 52466, 30-90 min after CFM-2, and 45-120 min after CFM-3. In addition, maximal anticonvulsant effect was observed 60-120 min after the IP administration of CFM-4 and at 90 min after CFM-5. The therapeutic index revealed that GYKI 52466 was slightly more toxic than CFM-2 and CFM-3. The time course of plasma levels of rats treated showed that peak plasma concentration was observed 45 min after IP administration of CFM-2 and CFM-3 and 75 min after CFM-4 and CFM-5. Following IP administration of CFM-3 two curves were detected, one is referred to the injected compound, and the other to its demethylated metabolite, which corresponds to CFM-2. Also. for the nitroderivative CFM-4 two curves were detected: one of an injected compound and the second due to its reduced metabolite (CFM-2). Finally, three different metabolites were detected in rat plasma after IP administration of CFM-5. The present study demonstrated that CFMs showed a significant protection against auditory stimulation during the period of peak plasma concentrations, suggesting a marked inhibition of those brain structures involved in the initiation and/or spreading of the audiogenic seizures.

Treatment with ribavirin+alpha interferon in HCV chronic active hepatitis non-responders to interferon alone: preliminary results.

Alpha interferon (IFN-alpha) represents the best therapy for HCV active chronic hepatitis, but only 25% of treated patients achieve a complete recovery. Several attempts have been made to increase this percentage. The objective of our study is to verify whether the combination ribavirin (R)+ IFN-alpha can lead to positive results in non-responders to treatment with IFN-alpha alone. The preliminary results for 5 subjects, all non-responders to IFN, treated with R+ IFN for 60 days and then IFN alone for 4 months more show that during the R+IFN treatment, 2 subjects presented a reduction in transaminase; a month after the suspension of R, ALT returned to pre-treatment values. The results are preliminary but we can say that this combination in the proposed doses and times in these subjects, cannot be considered adequate to modify the natural course of this disease.

Intrabiliary rupture of a hydatid liver cyst: a case report.

Intrabiliary rupture of a hydatid liver cyst is a rare occurrence which may result in the development of obstructive jaundice and cholangitis. In this report we discuss the diagnostic and therapeutic management of a patient in whom the parasitic nature of cholangitis was underestimated due to the small size and site of the cyst, and to the misleading concomitant presence of cholelithiasis.

Ultrasound monitoring of alcholic liver steatosis during glutathione (GSH) treatment.

In addition to clinical and laboratory alterations, the ultrasound picture in patients with liver steatosis may be quite clearly and closely connected to the histological aspects of this disease. Moreover, these patients have been found to have a reduced hepatocytic and plasmatic glutathione (GSH) level and consequently a reduced liver detoxicating capacity. The aim of this study was to evaluate the therapeutic action of exogenous GSH and its positive modifying role, not only in hepatic function indices (transaminase - GT), but also in the ultrasound picture, in a group of alcholic subjects suffering from carying levels of hepatic steatosis.
