Abstract
The evaluation of liver biopsies for infection can be a challenging and frustrating situation for diagnostic pathologists as well as clinicians. Patients often present with nonspecific symptoms, such as fever and elevated transaminases, leading to a broad differential diagnosis that typically includes malignancy and noninfectious inflammatory diseases in addition to infections. A pattern-based histologic approach can be extremely helpful in both making a diagnosis and guiding the next steps for the evaluation of the pathology specimen as well as the patient. This review discusses several of the more commonly encountered histologic patterns associated with hepatic infectious diseases, the most common pathogens with which they are associated, and helpful ancillary studies.

Abstract
Fever of unknown origin (FUO) poses a major diagnostic challenge in patients infected with human immunodeficiency virus (HIV). In this retrospective study, we sought to assess the clinical utility of percutaneous liver biopsy as a diagnostic aid for FUO in HIV-infected patients and identify the factors associated with a greater likelihood of a positive diagnostic yield form this procedure. A total of 101 HIV-infected patients with FUO, who had undergone percutaneous liver biopsy in an HIV care hospital, served as the study population. The results obtained from percutaneous liver biopsy were categorized into three groups: (i) diagnostic, (ii) helpful, and (iii) not helpful. Diagnostic and helpful results were classified as useful. The mean (SD) age of patients was 37.6 (6.9) years, and the median (interquartile range [IQR]) CD4 count was 18 (3-62) cells/mm(3). The median (IQR) duration of fever was 20 (8-30) days. Percutaneous liver biopsy was diagnostic in 51 patients (50.5%), helpful in 12 (11.9%) and not helpful in 38 (37.6%) patients. On multivariate analyses, elevation of serum alkaline phosphatase level (OR 1.27 per one time elevation from the upper normal range; 95% CI, 1.03-1.57; P = 0.023), and fever duration of less than 3 weeks (OR 3.82; 95% CI, 1.03-14.18; P = 0.046) was significantly associated with the likelihood of the biopsy findings being classified as useful. Our study supports the case for percutaneous liver biopsy as a useful diagnostic aid in HIV-infected patients with FUO.

Abstract
OBJECTIVE To determine practices among physicians in Canada for the assessment of liver fibrosis in patients with chronic liver diseases. METHODS Hepatologists, gastroenterologists, infectious diseases specialists, members of the Canadian Gastroenterology Association and⁄or the Canadian HIV Trials Network who manage patients with liver diseases were invited to participate in a web-based, national survey. RESULTS Of the 237 physicians invited, 104 (43.9%) completed the survey. Routine assessment of liver fibrosis was requested by the surveyed physicians mostly for chronic hepatitis C (76.5%), followed by autoimmune⁄cholestatic liver disease (59.6%) and chronic hepatitis B (52.9%). Liver biopsy was the main diagnostic tool for 46.2% of the respondents, Fibroscan (Echosens, France) for 39.4% and Fibrotest (LabCorp, USA) for 7.7%. Etiology-specific differences were observed: noninvasive methods were mostly used for hepatitis C (63% versus 37% liver biopsy) and hepatitis B (62.9% versus 37.1% liver biopsy). For 42.7% of respondents, the use of noninvasive methods reduced the need for liver biopsy by >50%. Physicians' characteristics associated with higher use of noninvasive methods were older age and being based at a university hospital or in private practice versus community hospital. Physicians' main concerns regarding noninvasive fibrosis assessment methods were access⁄availability (42.3%), lack of guidelines for clinical use (26.9%) and cost⁄lack of reimbursement (14.4%). CONCLUSIONS Physicians who manage patients with chronic liver diseases in Canada require routine assessment of liver fibrosis stage. Although biopsy remains the primary diagnostic tool for almost one-half of respondents, noninvasive methods, particularly Fibroscan, have significantly reduced the need for liver biopsy in Canada. Limitations in access to and availability of the noninvasive methods represent a significant barrier. Finally, there is a need for clinical guidelines and a better reimbursement policy to implement noninvasive tools to assess liver fibrosis.

A Rationale for the Use of F18-FDG PET/CT in Fever and Inflammation of Unknown Origin. INTERNATIONAL JOURNAL OF MOLECULAR IMAGING 2012; 2012:165080. [PMID: 23316356 PMCID: PMC3534311 DOI: 10.1155/2012/165080] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/06/2012] [Revised: 11/02/2012] [Accepted: 11/05/2012] [Indexed: 12/12/2022]
Abstract
This review focuses on the diagnostic value of hybrid F18-FDG Positron Emission Tomography/Computerized tomography (PET/CT) in fever of unknown origin (FUO) and inflammation of unknown origin (IUO). Due to the wide range of possible causes both FUO and IUO remain a clinical challenge for both patients and physicians. In addition, the aetiology of IUO shows the same variation in diseases as the FUO spectrum and probably requires the same diagnostic approach as FUO. There are numerous historically used diagnostic approaches incorporating invasive and non-invasive, and imaging techniques, all with relative high specificity but limited sensitivity. This hampers the generalization of these diagnostic approaches. However, recently published reports show that F18-FDG PET/CT in FUO and IUO has a high sensitivity and a relative non-specificity for malignancy, infection and inflammation. This makes F18-FDG PET/CT an ideal diagnostic tool to start the diagnostic process and to guide subsequent focused diagnostic approaches with higher specificity. In addition, F18-FDG PET/CT has a relative high negative predictive value. Therefore F18 FDG PET/CT should be incorporated in the routine diagnostic work-up of patients with FUO and IUO, preferably at an early stage in the diagnostic process.

Abstract
Numerous diseases that involve the gastrointestinal tract reveal the presence of granulomas on histological analysis. Granulomatous diseases can be either primary or secondary to environmental factors. Granulomas are dynamic structures composed of organized collections of activated macrophages, including epithelioid and multinucleated giant cells, surrounded by lymphocytes. The formation of granulomas is usually in response to antigenic stimulation and is orchestrated through cytokines, immune cells and host genetics. In this Review, the pathogenesis and etiologies of granulomas of the gastrointestinal tract and liver are discussed, as are the available diagnostic tools to help differentiate their various underlying etiologies. In addition, the role of granulomas in harboring latent tuberculosis is reviewed. The effects of tumor necrosis factor antagonists and interferon-α on the development of granulomas are also discussed.

Abstract
INTRODUCTION to evaluated the type histopathological hepatic lesions and opportunistic agents in Brazilian HIV-infected patients. METHODS we examined 52 percutaneous liver biopsies of 50 HIV-infected patients who had at least two of the following conditions: fever of unknown origin, unexplained severe emaciation, hepatomegaly or abnormal liver chemistry. The specimens were cultured for mycobacteria and fungi and stained by standard procedures. RESULTS reactive patterns, granulomatous hepatitis and chronic active hepatitis were verified in 28 (54%), 11 (21%) and 8 (15%) of the patients respectively. Opportunistic infections were diagnosed in 18 (36%) patients: mycobacteria in 12 (24%), Cryptococcus neoformans in 5 (10%) patients and mycobacteria and yeast was isolated from the same liver fragment in one patient. CONCLUSIONS mycobacteriosis was the most common opportunistic infection and liver tissue culture is an important method to detect opportunistic agents, even in the absence of histological lesions.

Abstract
Fever of unknown or uncertain origin (FUO) constitutes a common clinical challenge in patients infected with HIV. It is usually caused by disseminated opportunistic infection, and the relative frequency of each cause of FUO is influenced by multiple factors including CD4 count, geographic setting, and local prevalences of infectious agents, which may provide clues to the diagnosis. Infections presenting as FUO in the HIV population occur most often in the late stages of the disease and high diagnostic suspicion for mycobacterial disease should be maintained when evaluating these patients, particularly in areas of high prevalence. This article discusses the causes, diagnosis, and treatment of FUO in HIV-infected individuals.

Abstract
Tuberculosis is an important cause of fever of unknown origin. Travel, age, dialysis, diabetes, birth in a country with a high prevalence of tuberculosis, and immunoincompetence are among the most salient risks. Associated physical findings, radiologic evaluation, and hematologic and endocrinologic abnormalities may provide clues to the diagnosis. Both noninvasive and invasive diagnostic modalities are reviewed. Because diagnosis may be elusive, therapeutic and diagnostic trials of antituberculous therapy should be considered in all patients with fever of unknown origin who defy diagnosis.

Abstract
BACKGROUND Several serum markers reflecting extracellular matrix status have been correlated with liver fibrosis in non-HIV-infected patients with chronic hepatitis C infection. These indexes have been less examined in HIV/HCV-coinfected individuals. OBJECTIVE We aimed to evaluate the predictive value of serum markers for liver fibrosis in HIV-infected patients with chronic hepatitis C virus (HVC). METHODS Serum levels of metalloproteinases 1 and 2 (MMP-1 and -2), tissue inhibitors of matrix metalloproteinases (TIMP-1), procollagen type III N-terminal peptide (PIIINP), and hyaluronic acid (HA) were measured in HIV-infected patients with chronic hepatitis C at the time of obtaining a liver biopsy and before the consideration of anti-hepatitis C therapy. RESULTS One hundred and nineteen consecutive HIV-HVC coinfected patients were included. TIMP-1 (r = 0.6; P < 0.001), TIMP-1/MMP-1 ratio (r = 0.5; P < 0.001), TIMP-1/MMP-2 ratio (r = 0.3; P < 0.001), MMP-2 (r = 0.2; P = 0.044), PIIINP (r = 0.4; P < 0.001), and HA (r = 0.5; P < 0.001) were positively and significantly correlated with the fibrosis stage. In the multivariate analysis, TIMP-1 (odds ratio [OR] = 1.004, 95% confidence interval [CI]: 1.002 to 1.006, P = 0.001) and HA >95 microg/dL (OR = 6.041, 95% CI: 1.184 to 30.816, P = 0.031) were independently associated with liver fibrosis. The area under the curve of score to discriminate mild (F0-F1) from significant (F2-F4) fibrosis in the received-operating analysis using the variables TIMP-1 and HA was 0.84, with a sensitivity of 72.9% and a specificity of 83.1%. CONCLUSION TIMP-1 and HA were quite sensitive and specific for predicting the degree of liver fibrosis in HIV-infected patients with chronic hepatitis C. These parameters may become a noninvasive alternative to liver biopsy when the degree of liver fibrosis needs to be estimated.

Abstract
Hepatic tissue samples were obtained from 26 dogs humanely destroyed because of naturally occurring leishmaniosis (Leishmania infantum). None of the animals had palpable hepatomegaly or any other physical finding or historical evidence indicative of liver failure. However, serum biochemistry revealed hypoalbuminaemia (6/26), increased alkaline phosphatase (ALP) activity (15/26), and increased concentrations of total bilirubin (2/26) and post-prandial bile acids (4/26). Three main histological patterns were identified. In pattern 1 (3/26), the liver microarchitecture remained unchanged apart from the presence of individual or clustered macrophages in the sinusoids. In pattern 2 (20/26), there was multifocal, mild to moderate, granulomatous to pyogranulomatous infiltration of the hepatic parenchyma, particularly in the portal areas. Pattern 3 (3/26), which was the most severe form, was characterized by marked portal lymphoplasmacytic infiltration with occasional broaching of the limiting plate and extension into the adjacent parenchyma. In this pattern there was also mild portal fibrosis, together with lymphoplasmacytic aggregates within the parenchyma and small clusters of lymphocytes and plasma cells within the sinusoids. All three patterns were associated with hepatocyte vacuolation (15/26 dogs), and haemosiderin accumulation within the hepatocyte cytoplasm. Congestion was present in the liver of five dogs. No correlation was found between histopathological pattern and breed, sex, age, clinical manifestations, serum biochemical profile or parasite load in the hepatic tissue; patterns 1-3 may, however, represent sequential stages of hepatic leishmania infection during the chronic course of the disease.

Abstract
A bone marrow (BM) aspiration and biopsy is often believed to be a needed diagnostic procedure in the work-up of patients with fever of unknown origin (FUO), especially in the setting of AIDS. Is it worthwhile to proceed with this invasive diagnostic method? Clinical information obtained on 104 patients in whom AIDS had been previously diagnosed and who had been admitted with a presumptive diagnosis of FUO was retrospectively analyzed. Seventy-two cases met the inclusion criteria. A BM aspiration and biopsy had a low sensitivity as a diagnostic tool even in patients who had abnormal hematologic parameters. BM biopsy was also not helpful in diagnosing non-Hodgkin lymphoma (NHL) cases in this study. Although the incidence of NHL has risen since the emergence of HIV, the predominant types of lymphoma seen in AIDS patients are intermediate/high-grade lymphomas rather than low grade, and consequently, the incidence of BM involvement is low, decreasing the sensitivity of a BM biopsy as a diagnostic tool. These observations were validated in this study. The majority of BM biopsies in this series revealed diagnostic features of infections. This observation can likely be related to the high prevalence of HIV/AIDS patients in this community and opportunistic infections associated with this disease.

Abstract
OBJECTIVE Liver biopsy, the gold standard for assessing hepatitis C virus (HCV)-related fibrosis, is invasive and prone to complications. Our aim was to determine the operating characteristics of a non-invasive index of biochemical markers for the prediction of fibrosis in patients with HIV/HCV co-infection. DESIGN In a cross-sectional, cohort study in a French tertiary-care hospital 130 HIV/HCV-co-infected patients with a liver biopsy and serum were tested for markers of liver fibrosis. METHODS An index incorporating age, sex, alpha(2)-macroglobulin, apolipoprotein A1, haptoglobin, bilirubin, and gamma-glutamyl-transpeptidase (GGT), derived using multivariate logistic regression, was compared with liver histology. HIV-specific indices including the CD4 cell count and HIV-RNA load were also constructed. The diagnostic values of the indices were compared using receiver operating characteristic (ROC) curves. MAIN OUTCOME MEASURE Septal fibrosis (F2-F4) by the METAVIR classification. RESULTS By multivariate analysis, the most informative markers were alpha(2)-macroglobulin, apolipoprotein A1, GGT, and sex. The area under the ROC curve of the five-marker index was 0.856 +/- 0.035; not significantly different from the HIV-specific indices. On a scale from zero to 1.00, the five-marker index had a positive predictive value of 86% for scores greater than 0.60, and a negative predictive value of 93% for scores of 0.20 or less. These thresholds could reduce the necessity for liver biopsy by 55% while maintaining an accuracy of 89%. CONCLUSION An index including five biochemical markers accurately predicts significant fibrosis in patients with HIV/HCV co-infection, and may substantially reduce the necessity for liver biopsy.

Abstract
Fever is a common sign among patients with HIV infection and frequently leads to a medical consultation. It is generally caused by infections. The type of infection depends on the stage of the disease. Opportunistic infections occur only in the presence of severe immunodeficiency. A systematic approach will identify most causes of fever. Since the incidence of opportunistic infections has dramatically decreased with the use of highly active antiretroviral treatments, other causes of fever including immune restoration disease, neoplasm and drug-fever should be considered.

Abstract
Despite the marked improvement in patient survival and reduction in the incidence of HIV-related opportunistic infections with the introduction of potent, combination antiretroviral therapy, these infections remain a significant challenge in the management of HIV-infected patients. Ongoing issues that will require further study include a better characterization of immune reconstitution illnesses, other potential alterations in the natural history of opportunistic infections with antiretroviral therapy, and to what degree patients who experience failure of antiviral treatment become susceptible to various opportunistic processes.

Abstract
The liver is a common site of pathology in HIV-infected patients. In patients with controlled HIV and minimal immunosuppression, infection with hepatitis viruses is common owing to the risk factors of sexual transmission or parenteral drug use. In patients with AIDS, the liver is a common site of lymphohematogenous dissemination of several infectious pathogens. A thorough diagnostic approach leads to a diagnosis of most hepatobiliary processes. The therapeutic nihilism that has surrounded hepatic disease, including viral hepatitis, is unwarranted, because treatment of the underlying HIV and the hepatic process may improve the quality of life and longevity of these patients.
