RESUMO

AIM: To determine the causes and characteristics of fecal incontinence in men and to compare these features with those presented by a group of women with the same problem. METHODS: We analyzed the medical history, clinical and manometric data from 119 men with fecal incontinence studied in our unit and compared these data with those obtained from 645 women studied for the same problem. Response to treatment was evaluated after 6 mo of follow-up. RESULTS: Fifteen percent of patients studied in our unit for fecal incontinence were male. Men took longer than women before asking for medical help. Ano-rectal surgery was the most common risk factor for men related to fecal incontinence. Chronic diarrhea was present in more than 40% of patients in both groups. Decreased resting and external anal sphincter pressures were more frequent in women. No significant differences existed between the sexes regarding rectal sensitivity and recto-anal inhibitory reflex. In 17.8% of men, all presenting soiling, manometric findings did not justify fecal incontinence. Response to treatment was good in both groups, as 80.4% of patients improved and fecal incontinence disappeared in 13.2% of them. CONCLUSION: In our series, it was common that men waited longer in seeking medical help for fecal incontinence. Ano-rectal surgery was the major cause of this problem. Chronic diarrhea was a predisposing factor in both sexes. Manometric differences between groups were limited to an increased frequency of hypotony of the external anal sphincter in women. Fecal incontinence was controllable in most patients.

RESUMO

Antiviral therapy for recurrent hepatitis C in liver transplantation has been associated with the development of chronic rejection. The aim of this study was to assess the incidence, evolution, and risk factors associated with the development of chronic rejection during posttransplant hepatitis C virus antiviral therapy. Seventy-nine patients with posttransplant recurrent hepatitis C who were treated with pegylated interferon and ribavirin were prospectively followed. Liver biopsy was performed before antiviral therapy was initiated and when liver tests worsened during therapy. Pretransplant and posttransplant factors were analyzed as potential risk factors for the development of chronic rejection. Seven of 79 patients (9%) developed chronic rejection during antiviral therapy. The mean time from the start of treatment to the development of chronic rejection was 5.8 months (3-12 months). An analysis of factors associated with the development of chronic rejection showed that the use of cyclosporine as immunosuppression therapy (6 of 19 patients who received cyclosporine developed chronic rejection in comparison with only 1 of 57 patients who received tacrolimus; P = 0.0013), achievement of sustained virological response (P = 0.043), and ribavirin discontinuation (P = 0.027) were associated with the development of chronic rejection. In conclusion, the development of chronic rejection during posttransplant pegylated interferon and ribavirin therapy is a severe complication. The use of cyclosporine, ribavirin discontinuation, and viral infection elimination seem to be associated with the development of this complication. Liver Transpl 15:948-955, 2009. (c) 2009 AASLD.

RESUMO

Treatment of recurrent hepatitis C in liver transplant is controversial. The aim of our study was to evaluate the clinical and histological efficacy of pegylated interferon alpha 2b (PEG-IFN) and ribavirin therapy of recurrent hepatitis C after liver transplantation (LT). We prospectively included 47 liver transplant patients with: 1) a positive test for hepatitis C virus (HCV)-ribonucleic acid (RNA) in serum; 2) alanine aminotransferase (ALT) >45 UI/mL; and 3) a liver biopsy showing chronic hepatitis without rejection in the previous 2 months. Patients received PEG-IFN (1.5 microg/kg/week) and ribavirin (800-1,000 mg/day) for 12 months. Follow-up was based on biochemical (ALT), virological (RNA-HCV), and histological (liver biopsy) examinations. Follow-up lasted a minimum of 6 months after the end of antiviral therapy. Sustained virological response (SVR) was achieved in 23% of the patients. A total of 33 (70%) patients had normalized ALT levels at the end of therapy. Inflammatory portal and lobular score declined significantly in patients with SVR (P < 0.05) but not in nonresponder patients. Fibrosis did not change significantly in either group. SVR was significantly associated with low gamma-glutamyltransferase GGT (P = 0.04) and HCV-RNA levels (P = 0.03), a virological response at 12 weeks (P = 0.002) and patient's compliance (P = 0.04). Ten (21%) patients were withdrawn prematurely due to adverse effects. In conclusion, Therapy with PEG-IFN and ribavirin achieved SVR and a significant histological improvement in 23% of liver transplant recipients with chronic hepatitis C. Toxicity is an important drawback of this therapy.

RESUMO

Sézary syndrome is a non-Hodgkin's lymphoma of cutaneous origin that provokes severe cellular immunosuppression leading to greater susceptibility to opportunistic infections. We present the case of a male patient with a diagnosis of Sézary syndrome complicated by visceral leishmaniasis and Mycobacterium avium complex coinfection, with intestinal involvement of both pathogens -an exceptional finding in the absence of HIV infection. The diagnosis was confirmed by bone marrow biopsy and oral endoscopy with intestinal biopsy. Because of the severity of the infection and the failure of conventional treatment, miltefosine, a new antiparasitic agent still under investigation, was administered with favorable response. However the patient developed fatal pneumonia.

RESUMO

El síndrome de Sézary es un linfoma no hodgkiniano de origen cutáneo que provoca una inmunosupresión celular grave y, por ello, una mayor susceptibilidad a adquirir infecciones oportunistas. Presentamos el caso de un paciente diagnosticado de un síndrome de Sézary, complicado con leishmaniasis visceral y coinfección por Mycobacterium avium complex, con afección intestinal por ambos patógenos, hecho excepcional en ausencia de la infección por el virus de la inmunodeficiencia humama. La biopsia de la médula ósea y la endoscopia oral con toma de biopsias del intestino confirmaron el diagnóstico. La gravedad del cuadro y el fracaso de los tratamientos convencionales obligaron a emplear miltefosina, un nuevo fármaco antiparasitario en fase de investigación, con el que se obtuvo una respuesta favorable. Sin embargo, el cuadro se complicó con una neumonía de evolución fatal

RESUMO

BACKGROUND/AIMS: Circulating neutrophils from cirrhotic patients have a reduced capacity to generate superoxide anion (O(2)(-)), which might contribute to frequent bacterial infections in these patients. We studied the signal transduction pathways involved in the generation of O(2)(-) in neutrophils from 98 cirrhotic patients and 46 healthy controls. METHODS: We measured O(2)(-) production in neutrophils induced by fMLP, opsonized zymosan, TNF alpha, NaF, AlF(4)(-), A23187 and phorbol myristate acetate. Furthermore, we measured phospholipase C activity in neutrophils from healthy controls and end-stage cirrhotic patients. RESULTS: O(2)(-) production was decreased in neutrophils from patients in response to fMLP, opsonized zymosan and TNF alpha. Likewise, response of these cells to G-protein stimulation by fluorides was also decreased. These reduced responses correlated significantly with the degree of liver dysfunction. On the contrary, neutrophils from patients responded normally to A23187 and phorbol esters stimulation indicating that Ca(2+)- and PKC-dependent pathways are intact in these cells. Finally, phospholipase C activity was markedly reduced in neutrophils from end-stage liver cirrhosis. CONCLUSIONS: These data confirm that O(2)(-) generation by neutrophils is decreased in patients with cirrhosis, particularly in those with more severe liver dysfunction, and suggest that this defect involves phosphatidylinositol specific phospholipase C activity.

RESUMO

The effects of Orthotopic liver transplantation (OLT) on renal function and major vasoactive factors was assessed in end-stage cirrhotic patients. Renal function, mean arterial pressure, and plasma vasoactive hormones were measured In 22 cirrhotic patients with refractory ascites before and after OLT. Before OLT, mean arterial pressure, glomerular filtration rate, free water clearance, and fractional sodium excretion serum sodium levels were decreased. In addition, serum creatinine and plasma levels of vasoactive factors were increased. Ten of these patients fulfilled criteria of hepatorenal syndrome (HRS). Nine to 12 months after transplantation, renal function had improved and plasma levels of vasoactive factors had decreased significantly in all patients, including those with HRS. However, glomerular filtration rate remained subnormal and plasma endothelin-1 levels and plasma renin activity remained increased in most of them. In conclusion, OLT improves renal function in patients with end-stage liver cirrhosis, including those with HRS. However, renal function remains subnormal in most of these patients.
