Hepatic involvement in Wegener's granulomatosis: a case report

<p>Abstract</p> <p>Introduction</p> <p>We report the case of a 58-year-old Caucasian Greek man who presented with dry cough, fever, bilateral alveolar infiltrates and acute hepatitis.</p> <p>Case presentation</p> <p>After a lung biopsy, the patient was diagnosed with Wegener's granulomatosis. The diagnosis was supported by the presence of anti-proteinase-3 anti-neutrophil cytoplasmic antibodies. A liver biopsy demonstrated the presence of mild non-specific lobular hepatitis and periodic acid-Schiff positive Lafora-like inclusions in a large number of his liver cells. The patient was treated with prednisone and cyclophosphamide, which was followed by subsequent remissions of chest X-ray findings and liver function studies.</p> <p>Conclusion</p> <p>What makes this case worth reporting is the coexistence of liver inflammation with a biochemical profile of severe anicteric non-viral, non-drug induced hepatitis coinciding with the diagnosis of Wegener's granulomatosis. Our paper may be the first report of hepatic involvement in a patient diagnosed with Wegener's granulomatosis. The aetiological link between the two diseases is supported by the reversion of hepatitis after the immunosuppression of Wegener's granulomatosis. We favor the hypothesis that hepatic vasculitis may be the cause of acute hepatocellular necrosis.</p

Multi-organ failure with atypical liver granulomas following intravesical Bacillus Calmette-Guerin instillation

Bacillus Calmette-Guerin (BCG) intravesical instillation has been adopted in the treatment of patients with superficial bladder cancer. BCG-induced disseminated infection, though rare, has been associated with the histological finding of epithelioid granulomas in different organs, including the liver. We report the case of an adult patient with multi-organ failure, who developed sepsis, acute respiratory failure and acute hepatic failure with encephalopathy whose liver biopsy confirmed the presence of atypical, granulomatous-like lesions. Recovery was observed only after empirical therapy for Mycobacterium bovis with isoniazid, rifampicin, ethambutol and steroids was introduced. This case highlights the importance of a thorough patient assessment in order to exclude other more common causes of hepatic granulomas and to confirm diagnosis. Histological findings may be non-specific when the liver is involved in BCG-induced disseminated infection

Nitric Oxide, Ammonia, and CRP Levels in Cirrhotic Patients With Hepatic Encephalopathy Is There a Connection?

Goals: Comparison of nitric oxide (NO) levels in cirrhotic patients with and without hepatic encephalopathy (HE), evaluation of possible correlation between HE and other clinical or laboratory characteristics, and estimation of utilization of NO levels in clinical practice. Background: HE is a neuropsychiatric complication of cirrhosis. The exact pathogenetic mechanisms underlying the presence of HE are not known. However, dysfunction of the NO pathway and ammonia detoxification are thought to play a major role. Study: Sixty-seven cirrhotic patients, 36 (53.7%) without HE, and 31 (46.3%) with HE were included in the study. Eighteen healthy individuals were used as control group. Clinical and laboratory data, including ammonia and stable end products of NO using Griess reaction, were collected. Results: NOx levels were statistically significantly higher in cirrhotic patients (225.5 mu mol/L) than in control group [(67.94 mu mol/L) (P = 0.000)]. NOx levels were, also, statistically significantly higher in patients with HE compared with patients without HE (324.67 mu mol/L vs. 141.96 mu mol/L, P = 0.000). Significant correlation between the presence of HE and NOx, ammonia, C-reactive protein, albumin, Model for End-Stage Liver Disease score, and Child-Pugh classification revealed. NOx levels also correlated with severity of HE. NOx and ammonia are independent factors predicting HE according to regression analysis. Diagnostic accuracy for the diagnosis of HE using a combination of NOx and ammonia was superior compared with standalone NOx or ammonia utilization. Conclusions: NOx levels are correlated with the presence and severity of HE. NOx levels determination, in addition to ammonia levels, could contribute in diagnosis of HE
