RESUMO

A series of 132 patients who underwent liver transplantation for primary liver cancer was collected from three different Italian hospitals and studied for recurrence of hepatocellular carcinoma after liver replacement. Twenty-one patients (15.9%) had a neoplastic recurrence after an average follow-up period of 7.8 months after transplantation (range, 1-25 months); 15 (71%) occurred within the first 18 months after transplant and only two recurred later than 2 years. The sites of recurrence were grafted liver (19%), lung (19%), bone (14%), and other (5%). Eight patients (38%) had multiple organ involvement at the onset. After 1, 2, 3, and 4 years the overall survival rates were 62%, 43%, 29%, and 23%, respectively. The tumor factors related to early cancer recurrence after transplantation were diameter of nodules more than 3 cm (P < 0.05), tumor stage not meeting the "Milan criteria" (P < 0.03), and presence of peri-tumoral capsule (P < 0.05); the number of nodules, TNM stage, presence of vascular invasion, alpha-fetoprotein level more than 150 UI/l, pre-transplant chemoembolization and resectability of cancer deposits did not seem to be related to early recurrence. The prognosis differed in the 7 patients with resectable recurrences (57% 4-year survival) and the 14 patients with unresectable disease (14% 4-year survival) (P < 0.02). Better patient selection and new combined medical strategies could reduce the incidence of and mortality from liver cancer recurrence after transplantation. The role of surgical resection of recurrence should be further investigated.

RESUMO

Orthotopic liver transplantation (OLT) is used as a definitive treatment for end-stage liver disease and prolonged posttransplant survival has already been reported. The incidence of late mortality and graft morbidity is, however, not well defined and the role of primary viral disease in the long-term follow-up results is not clear. Data of posttransplant follow-up in 213 patients, 156 adults and 57 children, who survived at least 1 year were reviewed in order to define causes of graft dysfunction, graft loss and death. In 98 patients, 103 persistent graft dysfunctions were found. Thirty-four grafts were later lost [28 deaths and 6 successful retransplantations (re-OLT)]. The results were reviewed grouping patients according to their age and viral hepatitis status at the time of the transplantation. HBV-positive patients (51) showed 4 re-OLT (1 HBV), 3 liver-related deaths (2 HBV), 24 graft dysfunctions (8 HBV, 5 HCV), and 85.2% 6-year survival (based on 100% survival at 1 year). HCV-positive adults (28) showed 1 re-OLT, 3 HCV-related deaths, 24 graft dysfunctions (19 HCV), and 68.8% 6-year survival. HBV-HCV-positive patients (14) showed no graft loss and death, 10 graft dysfunctions (7 HCV, 1 HBV, 2 HBV-HCV), and 81.8% 6-year survival. HBV-HCV-negative adults (63) showed 3 non-hepatitis-related re-OLT, 5 liver-related deaths (2 HCV), 24 graft dysfunctions (6 HCV, 2 HBV), and 83.1% 6-year survival. HBV-HCV-negative children (49) showed no re-OLT, 1 HCV-related death, 14 graft dysfunctions (3 HCV), and 92.6% 6-year survival. HCV-positive children (8) showed 1 HCV-related re-OLT, 2 HCV-related deaths, 4 graft dysfunctions (3 HCV), and 81.3% 6-year survival. The main cause of graft dysfunction was hepatitis (45 HCV and 13 HBV), followed by technical complications (21), rejection (16), recurrent alcoholism (3), HIV infection (1), and unknown causes (4). In this long-term post-transplant follow-up series, viral hepatitis led to graft dysfunction in 58/103 (56.3%) cases, late graft failure was viral hepatitis-related in 11/ 20 (55%) cases, and, as a total, HCV infection was present in 45/58 (77.5%) cases of viral hepatitis-related graft damage. Looking at the timing of hepatitis-related graft failure, in 70% of cases death occurred after the 5th post-transplant year. In our experience, the occurrence of hepatitis, particularly HCV induced, was common and led to abnormal graft function, but the 6-year post-transplant survival (based on 100% survival at 1 year) in patients surviving for at least 1 year did not differ on the basis of the pretransplant viral hepatitis status. This finding may be consistent with the slow progression of the viral damage and longer follow-up results remain to be established. Nevertheless, data from the present study suggest that in long-term liver transplant survivors, the risk of deteriorating liver damage and eventual failure after 5 years remains only in those patients experiencing a viral hepatitis infection.

RESUMO

BACKGROUND: It has been reported that dual therapy with high doses of omeprazole and amoxycillin proves efficient for Helicobacter pylori eradication. AIM: To compare the efficacy, safety and tolerability of eradicating regimens with omeprazole/amoxycillin. METHODS: In this randomized multicentre study, 267 duodenal ulcer patients were treated for 2 weeks with omeprazole 40 bid (Group A) or 20 mg bid (Group B), respectively, and with amoxycillin 0.5 g. qid followed by 4 weeks of 20 mg omeprazole om. Helicobacter pylori status was assessed by both histology and urease test in the antrum and the corpus. The patients were then followed-up for 9 months. RESULTS: Helicobacter pylori infection was cured in 62.9% of group A (95% CI: 53.8-71.4) and in 44.8% of group B (95% CI: 35.6-54.3; p = 0.007). Healing was achieved in 91.9% of patients in group A (95% CI:85.7-96.1), and in 87.9% of patients in group B (95% CI:80.6-93.2). The estimated probability of being in ulcer remission for cured patients was 0.95 (95% CI: 0.90-0.99) and for the not cured was 0.41 (95% CI: 0.24-0.59; p = 0.0001). However, between the two treatment groups no significant differences in symptom relief or ulcer recurrence were observed. Both regimens were well tolerated with minor side-effects occurring likewise within the two groups. At two months in cured patients antral histology revealed a total (group A + B) prevalence of 13.7% of active chronic gastritis. CONCLUSIONS: This long-term, large-size study clearly indicates that dual therapy does not represent a truly effective eradication therapy and this regime cannot be recommended.

RESUMO

The presenting clinico-hematologic features of 386 patients with nonmyelomatous monoclonal gammopathy (MG) were correlated with the frequency of malignant transformation to evaluate the most important variables conditioning its evolution into multiple myeloma (MM) or Waldenström macroglobulinemia (WM). Most of the patients (335) had monoclonal gammopathy of undetermined significance (MGUS: 39 IgA, 242 IgG, 54 IgM): the remaining 51 patients (12 IgA, 39 IgG) fulfilled all of the MGUS diagnostic criteria (according to Durie) except that bone marrow plasma cell (BMPC) content was 10% to 30%, and so they were defined as having monoclonal gammopathy of borderline significance (MGBS). There were no significant differences between the MGUS and MGBS groups in terms of age, sex, or median follow-up. After a median follow-up of 70 and 53 months, respectively, 23 of 335 MGUS and 19 of 51 MGBS patients had undergone a malignant evolution. Univariate analysis of the IgA and IgG patients showed that the cumulative probability of the disease evolving into MM correlated with diagnostic definition (MGBS v MGUS), BMPC content (> or = 10% v < 5% and < or = 5% v > 5%) and reduced serum polyclonal Ig. In the IgG cases, there was also a significant correlation with detectable Bence Jones proteinuria, serum monoclonal component (MC) levels and age at diagnosis (> 70 v < = or 55 years). In the IgG cases as a whole, the same variables remained in the Cox model where the BMPC percentage was considered after natural logarithmic transformation and the monoclonal component as g/dL value. The relative risks of developing MM are the following: 2.4 for each 1 g/dL increase of IgG, serum MC, 3.5 for detectable light chain proteinuria, 4.4 for the increase of 1 unit in log. BMPC percentage, 6.1 for age > 70, 3.6 and 13.1 for a reduction in one or two polyclonal Ig. In conclusion, our study allows the identification of a particular subset of MGUS patients (MC < = or 1.5 g/dL, BMPC < 5%, no reduction in polyclonal Ig and no detectable light chain proteinuria) at very low-risk of evolution, who can be considered as having benign monoclonal gammopathies. We also describe a previously undefined group of MG patients (with monoclonal gammopathy of borderline significance) who are at high-risk of malignant evolution. These findings could have a considerable impact on the cost/benefit ratio of monitoring programs in these patients.

RESUMO

Interferon alpha is presently viewed as the first choice drug for treatment of chronic myeloid leukemia; however patients who are not eligible for this type of therapy are still treated with conventional chemotherapeutic agents as for instance hydroxyurea and/or busulfan. In a series of 23 patients with Philadelphia chromosome positive chronic myeloid leukemia who have been treated solely with busulfan, we have evaluated the relationship between total amount of drug required during the first 12 months of treatment and duration of the chronic phase. A statistically significant (p<0.005) inverse relationship between these two parameters was found, indicating that patients with low busulfan requirement during the first year of therapy have a better prognosis.

RESUMO

We report the clinical outcome of 105 essential mixed cryoglobulinemia (EMC) patients with renal involvement collected throughout 25 years in three renal Units of Milan. The median follow-up was 72 months since renal biopsy and 131 months since the clinical onset of EMC. Patient survival was 49% at 10 years after renal biopsy. Forty-two patients died primarily from cardiovascular and liver disease or infection, whereas 15 patients developed chronic renal failure. Two patients had a complete remission of the disease while 15 had a remission only of renal signs. Thirty-one patients are alive with persistent renal and extrarenal manifestations. Anti-HCV antibodies were retrospectively detected in 34 patients and were present in 85% of them. This variable was not included in the statistical evaluation. At multivariate analysis, age older than 50 years, purpura, splenomegaly, cryocrit levels higher than 10%, C3 plasma levels lower than 54 mg/dl, and serum creatinine higher than 1.5 mg/dl were independent risk factors for death or dialysis. In conclusion, several factors may influence the outcome of patients with EMC nephritis. Markers of disease activity and an impaired renal function can herald a bad prognosis. It should be stressed, however, that only a minority of patients eventually develop renal failure, probably because in the most severe cases patients die earlier.

RESUMO

Peripheral neuropathy (PN) is a frequent complication during primary macroglobulinemia (PM), whose immunological genesis has been suggested by various authors. This study involved 65 PM patients (44 men and 21 women aged 35-78), diagnostically divided into MGUS (31 cases), and indolent (IWM, 24 cases) or symptomatic (WM, 10 cases) Waldenstrom macroglobulinemia groups. All patients underwent neurological examination, including electrodiagnostic evaluation and the determination of the serum titre of antimyelin-associated glycoprotein (MAG). An evaluation was made of the prevalence of PN and its correlation with a series of hematological variables. The prevalence of PN was 31.6%: of those with PN, 73.1% manifested both clinical and electrophysiological signs of PN, primarily of the demyelinating type. Significant correlations emerged between the presence of PN and sex (M vs. F P = 0.0001), advanced age (P = 0.049), low MC levels (P = 0.025), high anti-MAG titres (P = 0.001) and high Hb levels (P = 0.001). No significant correlation with the diagnostic definition of PM was found, although the majority of cases with (particularly demyelinating) PN were MGUS or IWM. At multivariate analysis, the presence of PN significantly correlated with sex (P = 0.0001), age (P = 0.019), and anti-MAG titre (P = 0.001). Ten of the 26 PN cases showed no MAG reactivity. Significant correlations between PN and low serum MC levels/high MAG reactivity support the hypothesis of the antibody-mediated origin of many PN, and that the presence of PN depends on the characteristics of the proliferating pathological B clone, rather than on the tumor burden of the form of macroglobulinemia. Clinically, our data reconfirm the frequency of PN during PM and indicate simple clinicohematological variables useful for identifying patients at high neuropathic risk.

RESUMO

Duodenogastric reflux (DGR) and its effects were studied in patients with bile stones, operated by various bilio-digestive by-pass techniques, and followed up for 13-73 months. Ten patients underwent cholecystectomy and choledochoduodenostomy (CD), eight cholecystectomy and transduodenal sphincteroplasty (TDS) and ten cholecystectomy and endoscopic papillotomy (EP). The control group consisted of eight patients who had undergone minor surgery. DGR was studied by 99mTc-DISIDA scanning, and primary and secondary bile acids were assayed in reflux fluid. The effects were studied by gastroduodenoscopy and biopsies from the body of the stomach and antrum. Only patients operated by TDS (7/8) presented significant increases in DGR and bile acids (p < 0.008). Half the patients in this same group (4/8) had chronic atrophic gastritis and major clinical disorders. Some physiopathological mechanisms possibly involved in DGR and its effects are suggested.

RESUMO

The authors studied the red cell distribution width (RDW) index (obtained by Coulter Counter S Plus IV) in normal subjects and in patients with beta-thalassaemia trait and iron deficiency anaemia. Statistics and reference limits for the above three conditions are given. In order to make a differential diagnosis between beta-thalassaemia trait and iron deficiency anaemia, linear discriminant analysis was carried out. Global correct classification was 91.5% on our first sample of patients and 88.8% on a subsequent validation sample of microcytic patients. The percent of correct beta-thalassaemia trait diagnoses was 94.4% and 86.7% for the first and validation samples respectively. For iron deficiency anaemia correct diagnoses of 86.2% and 90.9% were achieved.

RESUMO

Sixteen adult patients with Schönlein-Henoch nephritis, selected by strict inclusion criteria, were studied retrospectively. At the time of discovery of the nephropathy, 11 patients had normal plasma creatinine and 5 other patients had renal insufficiency. All patients had renal biopsies, which were studied by both light and immunofluorescence microscopy. After a mean follow-up of 90.5 +/- 59.1 months (range 16-261), 3 patients were in chronic dialysis (18.7%), 8 other patients had renal function deterioration (50%), with creatinine clearance ranging from 31 to 60 ml/min. Four other patients had mild urinary abnormalities with normal plasma creatinine (25%) and only 1 patient was in complete clinical remission (6%). No clinical features at onset were predictive for the clinical outcome of the disease, while in the biopsies the percentage of crescents was higher in patients who developed renal insufficiency. High IgA serum levels were correlated (p = 0.0242) with a favorable course. It is concluded that Schönlein-Henoch nephritis of the adult carries a high long-term risk of renal dysfunction.
