Spontaneous bacterial peritonitis is a complication of ascitic patients with end-stage liver disease(ESLD); spontaneous fungal peritonitis(SFP) is a complication of ESLD less known and described. ESLD is associated to immunodepression and the resulting increased susceptibility to infections. Recent perspectives of the management of the critically ill patient with ESLD do not specify the rate of isolation of fungi in critically ill patients,not even the antifungals used for the prophylaxis,neither optimal treatment. We reviewed,in order to focus the epidemiology,characteristics,and,considering the high mortality rate of SFP,the use of optimal empirical antifungal therapy the current literature. 相似文献

Hepatitis C virus (HCV) is the major cause of chronic liver disease in hemophiliacs. To determine the effect of human immunodeficiency virus (HIV) on the natural history of HCV infection, we evaluated end-stage liver disease (ESLD) in 157 hemophiliacs (85 HIV positive and 72 HIV negative) with HCV infection for an average of 24 years. After adjusting for age at HCV infection, past or current hepatitis B surface antigen positivity, and history of alcohol abuse, we determined that the rate of ESLD was significantly greater among HIV-positive than among HIV-negative hemophiliacs (relative risk [RR], 3.72; 95% confidence interval [CI], 1.25-11.09), as was the adjusted RR for death due to ESLD (RR, 3.81; 95% CI, 1.19-12.16). Among HIV-positive hemophiliacs, crude RR for ESLD was lower, but not significantly so, with antiretroviral treatment (RR, 0.19; 95% CI, 0.03-1.14; P=.069) and increased with each decade of HCV infection (RR, 2.26; 95% CI, 1.42-3.59; P=.0006) and HIV infection (RR, 2.18; 95% CI, 1.36-3.49; P=.0013). These findings suggest that HIV accelerates HCV disease progression. 相似文献

Many of the complications of the diabetes are well studied but robust research documenting the cutaneous effects of the disease remains sparse. Various studies have suggested that the majority of patients with diabetes will suffer a skin disorder during the course of their disease and for some, the skin changes may even precede the diagnosis of diabetes. Cutaneous pathology of the diabetic foot and lower leg can arise as a result of the direct or indirect effects of diabetic complications. The most common manifestations include fungal and bacterial skin infection, nail disease and diabetic dermopathy. Other less commonly observed conditions include diabetic bullae, necrobiosis lipoidica diabeticorum (NLD), granuloma annulare and reddening of the soles. For many of the less common disorders, there is little in the way of effective treatment. However, much can be done in the clinical setting in the management of the more common manifestations such as bacterial and fungal infection. Fungal infection, in particular, although relatively inconspicuous, is a very common foot problem and if left untreated can threaten tissue viability in the diabetic foot leading to secondary bacterial infection and cellulitis. Management of fungal disease is often considered difficult due to high relapse and re-infection rates, although by introducing a combination of therapies including mechanical and pharmacological the success in treating this stubborn condition can be greatly improved. 相似文献

OBJECTIVE: To gain insight into the histopathologic characteristics of fungal infection in acquired immunodeficiency syndrome (AIDS). METHODS: A review was conducted of the histopathology for 162 patients with evident fungal infection. RESULTS: The microscopic appearance of esophageal candidiasis that was common in patients with single organ involvement revealed necrotic debris containing proliferating hyphae at the site of mucosal erosions without fungal invasion of underlying tissue. The incidence of oral and esophageal candidiasis was followed by that of pulmonary aspergillosis and Candida infection. Eighteen patients had generalized cryptococcosis, representing the commonest generalized fungal disease. The essential histologic features of the disease consisted of yeast cell proliferation with a histiocytic response, but only minor lymphocytic and neutrophilic components. This was different from the manifestations of both Candida and Aspergillus infections. The two histologic patterns recognized in the pulmonary cryptococcal lesions could be graded with respect to the degree and type of inflammatory reaction. The milder one consisted of small scattered foci of intra-alveolar cryptococcal proliferation with a histiocytic response. Another pattern involved massive cryptococcal infection, which might be simply more extensive than that in the former. Capillary involvement of alveolar septa was an important common finding in all 18 patients. 相似文献

Persons chronically infected with hepatitis C virus (HCV), some of whom may be coinfected with HIV and human T-lymphotropic virus type II (HTLV-II), are at high risk for end-stage liver disease (ESLD). We evaluated whether ESLD death was associated with premorbid HCV RNA level or specific HCV protein antibodies among persons with or without HIV/HTLV-II coinfection in a cohort of 6,570 injection drug users who enrolled in 9 US cities between 1987 and 1991. We compared 84 ESLD descendents and 305 randomly selected cohort participants with detectable HCV RNA, stratified by sex, race, HIV, and HTLV-II strata. Relative hazard (RH) of ESLD death was derived from the proportional hazard model. Risk of ESLD death was unrelated to the intensity of antibodies against the HCV c-22(p), c-33(p), c-100(p), and NS5 proteins, individually or combined, but it increased with HCV RNA level (RH(adj) = 2.26 per log(10) IU/mL, 95% CI: 1.45-5.92). The association between HCV RNA level and ESLD death remained significant after adjustment for alcohol consumption (RH(adj) = 2.57 per log(10) IU/mL, 95% CI: 1.50-8.10). Deaths from AIDS (n = 45) and other causes (n = 43) were unrelated to HCV RNA (RH(adj)= 1.14 and 1.29 per log(10) IU/mL, respectively). HIV infection was not associated with ESLD risk in multivariate analyses adjusted for HCV RNA. Men had an increased risk of ESLD death in unadjusted analyses (RH = 1.92, 95% CI: 1.15-3.56) but not in multivariate analysis (RH(adj) = 0.98, 95% CI: 0.48-2.88). Non-black patients were at increased risk for ESLD death (RH(adj)= 2.76, 95% CI: 1.49-10.09). In conclusion, HCV RNA level is a predictor of ESLD death among persons with chronic HCV infection. 相似文献

Many persons with hemophilia were infected with hepatitis C and B viruses (HCV, HBV) and HIV, but the consequences of these transfusion-acquired infections are poorly defined. We estimated the risk of HCV-related end-stage liver disease (ESLD) and the associations of age, HBV, and HIV with that risk. All 1816 HCV-seropositive hemophilic patients at 16 centers were followed for up to 16 years. Of these, 624 were HIV(-) and 1192 were HIV-coinfected; 135 had persistent HBV surface antigenemia, 1374 had resolved HBV infection, and 287 were HBV-uninfected. ESLD was defined as bleeding esophageal varices, hepatic encephalopathy, persistent ascites, or death excluding nonhepatic causes of these conditions. Competing risk models were used to estimate the annual hazard rate and cumulative incidence of ESLD. Proportional hazards models were used to estimate relative hazards of ESLD with covariates. ESLD developed in 127 of the HCV/HIV-coinfected participants, with an estimated 16-year cumulative incidence of 14.0% (95% confidence interval [CI], 11.6%-16.4%). Without HIV, 10 HCV-infected participants developed ESLD, for a significantly lower cumulative incidence of 2.6% (95% CI, 1.0%-4.3%, P <.0001). ESLD risk increased steeply with age in both groups. With HIV, ESLD risk was increased 8.1-fold (95% CI, 1.9-35.2) with HBV surface antigenemia, 2.1-fold (95% CI, 1.3-3.3) with fewer than 0.2 x 10(9)/L (200/microL) CD4(+) lymphocytes, and 1.04-fold (95% CI, 1.03-1.06) per year of age. Thus, HIV is associated with a markedly increased risk of HCV-related ESLD for persons with hemophilia, particularly with HBV infection, low CD4(+) lymphocytes, or older age. 相似文献

In hepatitis C virus (HCV) infection, virus load and the risk for HCV-related end-stage liver disease (ESLD) are increased among persons with human immunodeficiency virus (HIV) coinfection. To clarify these relationships, 42 hemophilic patients who developed ESLD and random samples from 164 hemophilic patients with HCV infection alone and 146 with HCV-HIV coinfection were tested for HCV load and genotype. HCV genotype was unrelated to HIV and age. In contrast, HCV load was higher with older age (P(trend)=.0001) and with HIV coinfection (6.2 vs. 5.9 log(10) genome equivalents/mL, P=.0001). During 16 years of follow-up of dually infected patients, ESLD risk was unrelated to HCV load overall (P(trend)=.64) or separately to HCV genotype 1 and genotypes 2 or 3 (P(trend)> or =.70). Irrespective of virus load, incidence of ESLD was marginally increased 2-fold (95% confidence interval, 0.8-5.6) with HCV genotype 1. Understanding the discordance between HCV load and ESLD, despite HIV's link to each of these, may help clarify the pathogenesis of HCV-related disease. 相似文献

Prior to 1990, many patients with inherited bleeding disorders were infected with hepatitis C virus (HCV). This study assessed the risk of end-stage liver disease (ESLD) in patients with hemophilia with chronic hepatitis C. Patients were infected between 1961 and 1990 and were followed up to August 2005. Of 847 anti-HCV(+) patients, 160 (19%) spontaneously cleared HCV and 687 (81%) developed chronic hepatitis C. Coinfection with HIV was present in 210 patients. After 35 years of infection the cumulative incidence of ESLD was 11.5% (95% CI, 8.2%-14.8%) in HIV(-) patients and 35.1% (95% CI, 29.2%-41.0%; P < .001) in patients coinfected with HIV. Independent risk factors of ESLD were HIV coinfection (hazard ratio 13.8; 95% CI, 7.5-25.3), older age at infection (hazard ratio 2.3 per 10 years; 95% CI, 2.0-2.8), alcohol abuse (hazard ratio 4.9; 95% CI, 2.5-9.6), and presence of HCV genotype 1 (hazard ratio 2.2; 95% CI, 1.1-4.2). With longer duration of HCV infection, the risk of developing ESLD is emerging in patients with inherited bleeding disorders. Risk factors for rapid progression to ESLD are alcohol abuse, coinfection with HIV, older age at infection, and presence of HCV genotype 1. 相似文献

End-stage liver disease(ESLD) is a leading cause of morbidity and mortality amongst human immunodeficiency virus(HIV)-positive individuals. Chronic hepatitis B and hepatitis C virus(HCV) infection,drug-induced hepatotoxicity related to combined antiretro-viral therapy,alcohol related liver disease and non-alcohol related fatty liver disease appear to be the leading causes. It is therefore,anticipated that more HIV-positive patients with ESLD will present as potential transplant candidates. HIV infection is no longer a contraindication to liver transplantation. Key transplantation outcomes such as rejection and infection rates as well as medium term graft and patient survival match those seen in the non-HIV infected patients in the absence of co-existing HCV infection. HIV disease does not seem to be negatively impacted by transplantation. However,HIV-HCV coinfection transplant outcomes remain suboptimal due to recurrence. In this article,we review the key challenges faced by this patient cohort in the pre- and posttransplant period. 相似文献
