Methotrexate treatment for sarcoid-associated panuveitis

OBJECTIVE: To determine the safety and efficacy of low-dose methotrexate (MTX) for sarcoid-associated panuveitis. DESIGN: Retrospective noncomparative case series. PARTICIPANTS: Twenty eyes from 11 patients were analyzed. Eight patients had sarcoidosis. Three patients were clinically suspected of sarcoidosis despite negative laboratory testing. All charts of patients with sarcoidosis and idiopathic uveitis seen by the Duke Uveitis Service from 1989 to 1997 were retrospectively reviewed. Those with sarcoid-associated or sarcoid-suspected panuveitis treated with MTX with a minimum of 6 months of follow-up were studied. INTERVENTION: Low-dose MTX was administered to patients weekly and patients were followed with serial ophthalmologic and medical examinations. MAIN OUTCOME MEASURES: Visual acuity, oral and topical corticosteroid requirements, anterior chamber inflammation, and ability to undergo successful cataract extraction were used to measure the efficacy of MTX therapy. RESULTS: After MTX treatment was initiated, 90% of eyes had preserved or improved visual acuity. Mean initial Snellen visual acuity was 20/62 and mean final acuity was 20/40 (P = 0.044). Of those patients initially requiring oral corticosteroids, the dosage was decreased in 100%, and they were completely discontinued in 86%. The mean initial oral corticosteroid dose was 26.6 mg and the mean final dose was 1.5 mg (P = 0.012). Topical corticosteroids were decreased in 63% of eyes. The mean initial use was once every 1.6 hours, and the mean final use was once every 3.9 hours (P = 0.001). Ninety-five percent of eyes had stabilized or decreased inflammation. The mean initial inflammation score was 1.2, and the mean final score was 0.5 (P = 0.007). Five of six eyes previously unable to have cataract extraction because of uncontrolled inflammation became quiet on MTX and underwent surgery. One hundred percent of these eyes had improved vision after surgery. Side effects were mild and transient or reversible. CONCLUSION: Low-dose MTX is an effective and safe adjunct to treat chronic sarcoid-associated panuveitis.     

Prolonged intrahepatic cholestasis in acute-onset, severe autoimmune hepatitis

A 72-year-old woman was admitted because of jaundice and hepatocellular dysfunction. She was diagnosed with autoimmune hepatitis from laboratory test results showing high titers of antinuclear antibodies and negativity for hepatitis viral markers. Steroid i.v. pulse therapy and oral administration of prednisolone were effective in improving the liver function test results, except for hyperbilirubinemia. Elevated serum bilirubin levels, of approximately 20 mg/dl persisted for more than 6 months, despite the administration of ursodeoxycholic acid. Insulin-glucagon therapy was given for normalization of transaminases and then withdrawn 3 weeks after admission, but it was resumed at 3 months, resulting in a dramatic decrease in serum bilirubin levels, which then normalized in 2.5 months. Liver biopsy 6 months after onset showed chronic active hepatitis with bile plugs. Insulin-glucagon therapy, because of its choleretic effect, may be worth continuing even after recovery of acute hepatic failure.     

Liver damage caused by sensitivity to anti-inflammatory agents]

Nonsteroidal antiinflammatory drugs may cause hepatic sensibilization and impairment. The incidence of these changes is low and referential data are scarce and related mainly to reaction which clinically corresponds to hepatic or cholestatic reaction. We present a patient who is sensitive to Diclofenac and has hepatic granuloma which developed after the use of the drug. History, clinical presentation, laboratory results, US examination of the liver and pathohistologic analysis of the hepatic biopsy sample enabled us to diagnose hepatitis with granulomatous impairment. Improvement of symptoms and signs of the disease was spontaneous and without administration of glucocorticoid drugs.     

Non-real-time computed tomography-guided percutaneous ethanol injection therapy for hepatocellular carcinoma undetectable by ultrasonography

Fibrosing cholestatic hepatitis (FCH) has recently been described after solid organ transplantation in patients with hepatitis C virus (HCV) infection. Typically, FCH is characterized by an ominous clinical course leading to progressive hepatic failure and death if liver transplantation is not performed. Two HCV-infected patients underwent cadaveric renal transplantation for end-stage renal disease resulting from membranous nephropathy and diabetic nephropathy. The time intervals between transplantation and the biopsy diagnosis of FCH for the two patients were 7 months and 10 years. Both patients presented with jaundice, hyperbilirubinemia, and mild-to-moderate elevations in serum aspartate aminotransferase. One patient was also found to have type II mixed cryoglobulinemia. Interferon-alpha therapy was begun after a diagnosis of FCH was established by liver biopsy. Liver test abnormalities normalized rapidly. When cholestatic hepatic deterioration develops in an HCV-infected organ allograft recipient, the diagnosis of FCH should be considered and a liver biopsy performed. Our observations indicate that FCH can respond to antiviral therapy.     

Granulomatous hepatitis attributed to the combination pyrimethamine-chloroquine

After her holiday in South Africa, a 50-year-old woman was admitted because of fever and pain in the upper abdomen. The laboratory tests showed moderately increased serum liver enzyme activities. The liver biopsy showed a granulomatous hepatitis. Further investigations revealed no evidence for sarcoidosis, tuberculosis or infectious hepatitis, nor for other granulomatous diseases or infectious diseases relevant to South Africa. Upon discontinuation of the malaria prophylaxis with Daraclor (pyrimethamine and chloroquine (sulphate)) the symptoms disappeared and the liver function tests returned to normal. It was concluded that Daraclor was the probable cause of granulomatous hepatitis in this patient. This adverse effect was not published before.     

Cyclosporine-related encephalopathy following allogeneic bone marrow transplantation

Idiopathic granulomatous hepatitis is a rare disease of unknown cause that is characterized by recurrent fevers and granuloma in the liver. Attempts to define an exact etiology of the fever of granulomatous hepatitis frequently do not yield a precise diagnosis. Idiopathic granulomatous hepatitis was confirmed after a thorough work up and negative cultures and serologies were obtained, and in the absence of another condition that could lead to granulomas in the liver. We have experienced a 67-year-old female patient who presented with prolonged fever for 2 months and revealed granuloma in liver biopsy. She was treated with glucocorticosteroid and defervescence resulted.     

Radiation-induced malignant fibrous histiocytoma of the head and neck

OBJECTIVE: To compare in a randomized prospective study the infective complication rates of a single intravenous dose of co-amoxiclav given alone before transrectal prostatic biopsy with an intravenous dose followed by oral co-amoxiclav for 24 h. PATIENTS AND METHODS: Eighty-three patients undergoing prostatic biopsy were randomized to receive 1.2 g co-amoxiclav intravenously and then either three further doses of oral co-amoxiclav (Group 1) or no further antibiotics (Group 2). The evaluation included analysis of a mid-stream urine (MSU) sample before and 72 h after biopsy, and the recording of oral temperatures and symptoms in the first 44 patients. Patients with symptomatic urinary tract infections (UTIs), prostatitis, indwelling catheters, diabetes and those receiving steroid therapy were excluded. RESULTS: Eight patients, four from each treatment arm, were found to have asymptomatic UTIs from their MSU before biopsy. Excluding these patients, four patients (11%) from Group 1 and six from Group 2 (16%) had positive MSUs at 72 h; two patients from Group 2 and one from Group 1 required admission to hospital. Of the patients returning symptom and temperature charts, a further six (14%; three from each group) reported signs and symptoms suggestive of infection despite negative urine cultures. CONCLUSIONS: There was no statistically significant difference in the rate of positive MSUs between the groups. The incidence of infections was considerably higher than in previously published series where other antibiotics were used, suggesting that co-amoxiclav is not the drug of choice for transrectal prostatic biopsy.     

Concussion history in elite male and female soccer players

BACKGROUND/AIMS: Recent studies in primary biliary cirrhosis have reported the detection of serum antibodies against Mycobacterium gordonae and of mycobacterial DNA in liver sections. The aim of this study was to investigate whether mycobacterial DNA is present in liver biopsy material in primary biliary cirrhosis. METHODS: Archival liver biopsy specimens from 11 patients with primary biliary cirrhosis (10 female, mean age 52 years) and 11 patients with autoimmune hepatitis (10 female, mean age 53 years) were identified. Positive control tissue comprised five archival lymph node specimens from patients with tuberculous lymphadenopathy, three of which had stained positive on ZN staining, and also a liver biopsy specimen from a patient with tuberculous hepatitis (ZN positive). Fixed sections were deparaffinised and DNA was extracted by mechanical disruption with glass beads. DNA was purified by use of diatoms and lysis in guanidinium thiocyanate in a technique previously validated for archival DNA. Primers were directed to amplify a partial 16S ribosomal RNA gene yielding the species-specific character for mycobacteria, and also to amplify the constitutively-expressed human gene GAPDH. RESULTS: The polymerase chain reaction was shown to be capable of detecting 1 fg of M. gordonae DNA in 'spiked' samples, equivalent to 1-5 bacterial cells. No mycobacterial DNA was detected in liver biopsy samples from either the primary biliary cirrhosis or autoimmune hepatitis groups. Of the tuberculous control sections, mycobacterial DNA was detected in four of five lymph nodes and the liver biopsy specimen. GAPDH amplification was detected in all tested samples from liver disease and tuberculous control samples. CONCLUSION: These data do not support a role for mycobacteria in the aetiology of primary biliary cirrhosis.     

Serum hyaluronate predicts response to interferon-alpha therapy in patients with chronic hepatitis C

BACKGROUND/AIMS: The response to interferon therapy for chronic hepatitis is known to decrease with progression of the hepatic fibrosis. On the other hand, serum hyaluronate reflects hepatic sinusoidal capillarization or liver cirrhosis, and also serum type IV collagen, which is one of the main components of the basement membrane, rises with the progression of hepatic fibrosis. In this study, the relationship between the degree of hepatic fibrosis and the response to interferon-alpha was determined retrospectively in patients with chronic hepatitis C. In addition, whether the measurement of serum hyaluronate and type IV collagen before interferon-alpha therapy was useful for predicting the response to interferon-alpha therapy in chronic hepatitis C was determined. MATERIALS AND METHODS: Thirty-seven patients with elevated serum ALT levels for at least 6 months and histologically determined chronic hepatitis were studied. All patients were positive for anti-HCV and negative for hepatitis B surface antigen. Twenty-eight healthy adults with normal blood biochemical data, who were negative for hepatitis B antigen and HCV antibody tests, had limited alcohol intake were used as controls. The test group was given IFN-alpha by intramuscular injection for 14 days, and then were treated 3 times per week for 24 weeks. RESULTS: The extent of hepatic fibrosis, particularly, perisinusoidal fibrosis (P < 0.01) was significantly greater in nonresponders than in responders. The mean serum hyaluronate and type IV collagen levels were more elevated in nonresponders than in responders, especially, the serum hyaluronate level showed a significant difference (P < 0.01). Most of the patients having a serum hyaluronate level of more than 100 ng/ml were nonresponders who had chronic active hepatitis with bridging necrosis on liver biopsy. Serum hyaluronate and type IV collagen levels showed significant positive correlation with degree of the portal fibrosis (P < 0.01), perisinusoidal fibrosis (P < 0.001) and focal necrosis (P < 0.01) in histological findings of liver biopsy specimens. CONCLUSION: These results suggest that serum hyaluronate and type IV collagen levels reflect the extent of the hepatic fibrosis in chronic hepatitis C and also that serum hyaluronate level predicts the response to interferon-alpha therapy in patients with chronic hepatitis C.     

Clinical features and treatment of sarcoidosis involving the central nervous system

PURPOSE: The purpose of this study was to investigate the clinical features, diagnosis, and treatment modalities of three cases with neurosarcoidosis, which involved the central nervous system (CNS). CASES: Three men with neurosarcoidosis, aged 27, 29 and 60 years, are presented. Two of them had previously been given a diagnosis of sarcoidosis. The clinical symptoms of these cases included diabetes insipidus, pituitary dysfunction, seizure, mental disorder, visual field disturbance and pyramidal tract signs. In these cases, CT scan and MRI showed the presence of a tumor near the pituitary gland, diffuse nodules in the subarachnoid space or meningoencephalitis associated with angitis. The level of angiotensin converting enzyme (ACE) in the sera and in the cerebrospinal fluid, were elevated in the two cases who had no brain biopsy. All three cases were treated with steroids; two of them received pulse steroid therapy. RESULTS: The two cases who received pulse steroid therapy responded quickly, with improvement in clinical features, serum ACE levels and neuroradiological findings. Under oral administration of steroids, all three cases recovered with complete remission of neurosarcoidosis except for endocrinological symptoms. DISCUSSION: The main pathological changes of neurosarcoidosis are granulomatous angitis of the venular walls and occasionally, of the capillaries near the meninx and Virchow-Robin space. The patients also had symptoms of secondary meningoencephalitis. These changes were mainly located in the hypothalamus and pituitary gland. The patients had complex symptoms resulting from endocrine system granuloma, as well as from cerebral ischemia. The severity of the disease and effectiveness of treatment, can be evaluated by measuring ACE levels in the cerebrospinal fluid (over 1. 0 IU/l), and by Gd-enhanced MRI. Early pulse steroid therapy with subsequent oral steroid administration is thought to be important for neurosarcoidosis treatment, in order to prevent irreversible damage in the CNS.     

Histo-pathological evaluation of response to 6 and 12 months of interferon alpha therapy

BACKGROUND AND AIMS: Interferon-alfa (IFN-alfa) has recently been introduced for chronic C hepatitis treatment; however, the response rate is merely 25-50%. The aims of this follow-up study were to compare the efficacy of 6 and 12-month IFN-alfa treatment via liver biopsy scores and to evaluate the correlation with the biochemical response. PATIENTS AND METHODS: 20 chronic C hepatitis patients were studied. 10 patients received IFN-alfa therapy for 6 months, and 10 for 12 months (3 million units three times a week). Liver biopsy material was taken before and after therapy. RESULTS: There was a significant serum alanine aminotransferase (ALT) level improvement in both groups, but a significant histological improvement in necroinflammatory activity (grade) occurred only in the 12-month group. The Chevallier stage scores demonstrated a significant progression in both groups. CONCLUSIONS: 12-month IFN-alfa treatment affords a better response in the liver histology grade and serum ALT level, but not the stage; a normal ALT does not guarantee hepatitis inactivity. Liver biopsies appear indispensable for monitoring the fibrotic changes in chronic C hepatitis.     

The therapeutic efficacy of interferon-alfa-2a (Roferon-A) in chronic hepatitis C

THE AIM OF THE STUDY: Evaluation of 6-month treatment with roferon-A of patients with chronic hepatitis C (CHC) and comparison of the treatment regimens. MATERIAL AND METHODS: 79 CHC patients received roferon-A for 3 months in a dose 6,000,000 IU 3 time a week. In case of the response to treatment was continued for the next 3 months (3,000,000 IU 3 times a week). Clinical-laboratory findings, results, of EIA and liver biopsy histology were examined. RESULTS: Primary remission was achieved in 71.8% of cases. 36.9% of patients developed recurrences including 14.1% recurrence arising in the course of therapy. Stable remission was obtained in 32.4% of patients. 28.2% patients were non-responders. Side effects were mild, discontinuation of the treatment was necessary only in 7% of cases. CONCLUSION: Roferon-A administration in a dose 6,000,000 IU for 24 weeks is optimal both as related to cost and efficacy of the treatment.     

Methyldopa Hepatitis. A report of six cases and review of the literature

Six cases of methyldopa hepatitis, including two in which the patients died are reported; and 77 cases from the literature are reviewed. Patients in whom severe hepatotoxic reactions to methyldopa develop usually complain of prodromal symptoms typical of hepatitis, often with fever, one to four weeks after therapy is initiated. Jaundice, when it occurs, is usually manifest within three months. Asymptomatic, transient elevations of serum transaminase levels may occur in patients receiving methyldopa. However, since the clinical and histologic features of hepatic injury from methyldopa are indistinguishable from viral hepatitis, it is suggested that the incidence of this iatrogenic disease is higher than generally appreciated. Serum transaminase levels should be determined at the initiation of therapy with methyldopa and four weeks later. Moreover, any patient who has unexplained fever or the prodromal symptoms of hepatitis should undergo liver chemistry studies immediately.     

Anti-thyroid autoantibodies in hepatitis C. Thyroid function after interferon therapy in 4 patients

Four female patients had chronic hepatitis C associated with antithyroid autoantibodies. Hepatitis C virus infection was evidenced by liver biopsy and a positive-four-antigen recombinant immunoblot assay. All four patients were euthyroid before interferon therapy. Recombinant interferon alpha was given at a dose of 3 millions units three times a week for 6 months. At the end of the treatment, serum aminotransferase levels were within the normal range. Two patients progressed to hypothyroidism and 2 patients remained euthyroid. One year after the end of the treatment, only one patient had hypothyroidism and another had normal serum aminotransferase levels. These case-reports suggest that interferon administration may induce thyroid dysfunction in patients with antithyroid autoantibodies at the beginning of treatment. Thyroid dysfunction may be reversed when cytokine is withdrawn.     

The effect of probucol on intimal thickening of autologous vein grafts in hyperlipidemic rabbit

OBJECTIVE: To define whether there is any relation between the iron status of patients with hepatitis C virus (HCV) chronic liver disease and their response to interferon therapy. DESIGN: To evaluate the long-term response to 1 year of interferon therapy with addition of phlebotomies after 3 months of treatment if at that time alanine aminotransferase (ALT) had not normalized in a group of patients with HCV-positive chronic liver disease whose iron status had been characterized. SETTING: A northern Italian hospital. PARTICIPANTS: Fifty-eight anti-HCV-positive patients (four HCV-RNA negative) with biopsy proven chronic hepatitis and no evidence of iron overload as indicated by normal transferrin saturation at the time of enrollment in the study. INTERVENTION: Three times a week intramuscular injection of alpha interferon 3 MU for 1 year with addition of phlebotomies (350 ml/week) till iron depletion if after 3 months of interferon therapy ALT had not normalized. RESULTS: A long-term response was observed in 19 of the 52 patients who completed the treatment, four HCV-RNA negative and 15 positive. The four RNA-negative and seven of the 15 RNA-positive long-term responders had been treated with interferon alone, and the other eight also with phlebotomies. At univariate analysis only HCV genotype, gamma-glutamyltranspeptidase and liver iron concentration were significantly associated with response whereas sinusoidal iron deposition was of borderline significance. No association was found with sex, age, duration of disease, histology, Knodell score, transferrin saturation %, serum ferritin, hepatocytic iron score, and portal iron score. HCV-RNA serum levels, measured in 29 patients, did not correlate with response. At multivariate analysis liver iron concentration was still significant and one unit reduction of liver iron concentration (natural logarithm transformed) was associated with 2.95 odds ratio of response. CONCLUSION: These results indicate that iron in the liver is more closely related to response to interferon than the other variables considered, including HCV characteristics.     

"Remembrance and reflection"

Takayasu's arteritis (TA) is a chronic inflammatory arteriopathy affecting the large vessels and has been described predominantly in young adult women. In children it presents as an aggressive disease usually requiring chronic corticosteroid therapy. At present, low dose oral methotrexate (MTX) appears to be an effective steroid-sparing agent in adult patients with active TA. We report a 4-year-old child with Takayasu's arteritis who was initially placed on oral prednisone (2 mg/kg/day) therapy. Three months later, low-dose oral MTX (10 mg/m2/week) was added. Prednisone was successfully tapered over the following year to 0.2 mg/kg every other day. A repeat angiography following 12 months of therapy revealed a dramatic improvement of the vascular lesions. No toxicity was observed with MTX therapy. In conclusion, low-dose oral MTX appeared to be an efficient, safe and steroid-sparing agent in the treatment of a young child with TA.     

Response to methotrexate in a patient with idiopathic eosinophilic fasciitis, morphea, IgM hypergammaglobulinemia, and renal involvement

A 35-year-old man with idiopathic eosinophilic fasciitis (EF) and morphea developed renal disease characterized by microscopic hematuria, nephrotic range proteinuria, and rapidly progressing hypertension, an association that has not previously been reported in EF. Initial clinical symptoms of EF began in July 1989; peripheral eosinophilia peaked at 30% in August 1990; an abnormal urinalysis was first observed in March 1992 and subsequently a renal biopsy was performed. Renal biopsy demonstrated focal segmental glomerulosclerosis and a subepithelial immune-type deposit. Partial fasciectomy and a course of methotrexate resulted in overall functional improvement of his extremities. Proteinuria and hematuria was reduced during methotrexate therapy.     

Acute liver failure following tetrabamate

Tetrabamate (Atrium), a composite preparation of phenobarbital, difebarbamate and febarbamate, is widely used to reduce ethanol withdrawal symptoms such as tremor, agitation and anxiety. Generally this drug is well tolerated and a few cases of reversible hepatitis as well as clinically mild symptoms of asthenia have been described. We report on a 28-year-old female patient admitted to hospital with acute liver failure after treatment with tetrabamate because of alcohol withdrawal symptoms. Liver biopsy revealed a drug-induced toxic alteration with extensive panlobular necrosis without signs of alcoholic hepatitis. Under supportive therapy liver parameters normalized in 3 months. In view of this potentially lethal adverse effect of tetrabamate, it should not be used for ethanol withdrawal symptoms.     

Systemic chemotherapy for psoriasis: a national survey

A questionnaire that was mailed to 510 randomly selected dermatologists in the United States surveyed their use of three systemic chemotherapeutic agents for the treatment of psoriasis during the two-year period of 1973 to 1974. Methotrexate was used by 52% of the surveyed dermatologists, while hydroxyurea and azaribine were used by 10% and 2%, respectively. Seventy-five percent of the dermatologists who used methotrexate treated ten or fewer psoriatic patients with this drug. Multiple dose therapy with methotrexate divided over a period of 36 hours each week was the preferred schedule of 66% of the dermatologists. Liver biopsy specimens and creatinine clearance tests were obtained for only 17% and 35% of patients, respectively, prior to initiating methotrexate therapy. The estimated number of dermatologist-treated psoriatics nationwide receiving methotrexate is 25,000.
