A 26-year-old female was admitted to our hospital because of arthralgia and general fatigue. On examination, she had malar rash and arthritis. Laboratory data revealed AST, ALT and gamma-globulin elevation, antinuclear antibody and double-stranded DNA antibody positivity, and LE cell phenomenon. Liver biopsy showed marked lymphocytic infiltration and slight fibrosis in the portal areas. She was diagnosed with lupoid hepatitis, and also satisfied the criteria for SLE including malar rash, arthritis, immunologic disorder and antinuclear antibody. She was administered prednisolone, after which AST and ALT decreased. She developed psychosis and her electroencephalogram showed diffuse slow waves corresponding to psychosis by SLE. Lupoid hepatitis is frequently associated with various systemic manifestations. However, only a few cases of lupoid hepatitis satisfying the criteria for SLE associated with psychosis have been reported.

In 1997, the Italian Ministry of Health created a special programme for the controlled distribution of deferiprone to collect data and to evaluate its safety and effectiveness in long-term use. Five hundred and thirty-two thalassaemia patients from 86 treatment centres were enrolled in this programme. One hundred and eighty-seven patients (32%) experienced a total of 269 events that led to a temporary interruption or, in some cases, to a discontinuation of treatment. The incidence of agranulocytosis and milder neutropenias were 0.4/100 and 2.1/100 patient-years respectively. Neutropenia occurred predominantly in younger and non-splenectomized patients. Transient alanine transaminase increase, gastrointestinal discomfort and arthralgia were the other most commonly reported events. Ferritin levels showed a significant decrease in time after 3 years of therapy. This is the largest number of deferiprone-treated patients to have been reported to date. These data show that the drug was effective in reducing serum ferritin levels and the incidence of adverse events was not greater than the frequency reported in clinical trials.

The purpose of this study was to determine if the adverse effects of interferon (IFN) in hepatitis C patients could be reduced by treatment with Japanese Oriental (Kampo) medicine. Twelve patients with chronic hepatitis C were treated with a combination of IFN-beta and either Mao-to or Dai-seiryu-to (groups A and B), and 16 patients were treated with IFN-beta alone (group C). Mao-to was administered to eight patients and Dai-seiryu-to was administered to four in groups A and B, respectively. Adverse effects were evaluated by clinical and laboratory examinations. The severity of symptoms was daily self-classified into four categories (1: none, 2: very slight, 3: moderate, and 4: serious), using a questionnaire consisting of 29 items. Scores of symptom such as discomfort and fever in group A, and discomfort, general malaise, paresthesia and arthralgia in group B were significantly lower than those in group C (p < 0.05). In all patients, HCV-RNA was negative at the end of the treatment, and serum alanine aminotransferase (ALT) levels had normalized transiently in all group A and B patients with genotype 1b by 2 weeks after cessation of IFN treatment. This study indicates that Kampo medicines are useful for reducing the adverse effects accompanying IFN treatment in patients with chronic hepatitis C without reducing the antiviral effects.

Following an acute episode of undifferentiated collagenosis/autoimmune disease with joint pain, a 50-year-old female patient with known long-standing chronic hepatitis B was treated orally with corticosteroids (30 mg prednisolone in decreasing doses over a period of six months). During this treatment, exacerbation of hepatitis B and massive flare-up under simultaneous treatment with lamivudine occurred (GOT 530 U/L, GPT 791 U/L). Serology was positive for HBs-Ag and anti-HBc-lgM. HBV-DNA titer was > 400,000 copies/ml in polymerase chain reaction. Considering the increased risk of reactivation of autoimmune phenomena during a six months therapy with interferon-alpha, an intensive combination therapy with interferon-beta and -gamma (2 weeks: 1 x 3 MIU nIFN-beta Fiblaferon i.v.; 3 weeks: 1 x 3 MIU nIFN-beta i.v. plus 1 x 50 microg rIFN-gamma Imukine) was carried out over five weeks. After two months this resulted in a complete viral and biochemical response. During an observation period of twelve months no reactivation of the autoimmune disease occurred.

Recombinant human interleukin 12 (IL-12) is an immunomodulatory cytokine that is active against several viruses. Treatment options in patients with chronic hepatitis C with nonresponse to interferon (IFN)-based therapy are limited. Prior dose-ranging studies have indicated drug tolerability and transient suppression of hepatitis C virus (HCV) RNA by IL-12. The aim of this study was to determine the safety and efficacy of prolonged IL-12 therapy in patients who have failed treatment with IFN-alpha +/- ribavirin. A total of 225 patients at 21 U.S. sites who had a history of nonresponse to IFN-alpha or combination IFN-alpha plus ribavirin for treatment of HCV were randomized to 500 ng/kg IL-12 or placebo subcutaneously twice weekly for 12 weeks. The groups were then unblinded; patients receiving IL-12 continued for another 36 weeks, and the placebo group received 48 weeks of treatment with IL-12 in an open-label fashion. HCV RNA, serum alanine aminotransferase (ALT) level, and a repeat liver biopsy were assessed at 24 weeks following therapy. Approximately 1% (2 of 160) of nonresponsive patients enrolled for treatment had a sustained virologic response to IL-12 therapy, but 3% (7 of 225) developed severe adverse events probably related to treatment, resulting in early termination of the trial. Common adverse effects reported by most patients included chills, fever, fatigue, headache, and arthralgia. At termination of the study, 160 patients had received at least 8 weeks of treatment with IL-12. Paired liver biopsy specimens were available for evaluation in 54 patients, but there were no significant changes in Knodell fibrosis or histologic activity index (HAI) scores. In conclusion, IL-12 as monotherapy at the doses used in this trial for chronic hepatitis C has low efficacy, was poorly tolerated, and is unlikely to provide an alternative to conventional IFN-based therapy.

A 40-year-old woman with a history of fever and arthralgia since age 17 had received long-term prednisolone (PSL) therapy. She was diagnosed with Takayasu's arteritis in 1980 and given PSL. The symptoms were well controlled until she developed itching in 1998. Laboratory tests showed elevated levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyltranspeptidase, total cholesterol, and immunoglobulin M (IgM). She tested positive for anti-mitochondria antibody and for both IgG and IgM anti-pyruvate dehydrogenases. Liver biopsy findings were typical of primary biliary cirrhosis (PBC). Our patient's clinical course suggested that an adequate amount of PSL to control Takayasu's arteritis does not necessarily prevent the development of PBC.

Between the dates of May 4th-August 6th 2002, 46 cases were detected with abdominal pain nausea, vomiting, arthralgia/myalgia, headache, fever, diarrhea and rash, in the middle Blacksea and north inner Anatolia regions. Their laboratory findings yielded elevated levels of liver enzymes (AST, ALT, LDH), leucopenia and thrombocytopenia. As the infection was treated easily with tetracyclines, clinical diagnosis was considered to be rickettsiosis or ehrlichiosis. Serum and blood samples obtained from some of the patients were tested against Rickettsia, Ehrlichia, Leptospira and Coxiella, in the national and international laboratories. Samples from 19 patients were sent to National Reference Centre and WHO Collaborating Centre for Rickettsial Reference and Research Laboratory, France, and 7 of them were reported as acute Q fever while 8 of them were reported as passed Q fever (QF) cases. In May 2003, new cases with similar symptoms have been reported from the same regions, with different epidemiologic and serologic findings (tick exposure history was higher, response to tetracycline was lower, C. burnetii antibodies were negative), indicating a viral etiology. The samples of these patients have been sent to National Reference Centre and WHO Collaborating Centre for Arboviruses and Viral Heamorrhagic Fevers, France, and the initial reports were marked as Crimean Congo hemorrhagic fever virus (CCHFV). Then the serum samples of previous 26 patients which were stored in National Serum Bank have been retrospectively investigated for viral aetiology in the same center, and 17 of them have been found positive for CCHFV IgM antibodies. Four of these patients were diagnosed as acute QF in 2002, one was passed QF, 2 were negative for QF and 10 were patients not investigated for QF. As a result, the detection of the both infections together in the same area shows the essential need for further epidemiological investigations.

The aim of our study was to compare the prevalence of mixed cryoglobulinemia in a group of HCV positive/HIV- negative patients with respect to a group of HCV/HIV co-infected subjects. Between September 2002 and May 2003, 58 patients with proven HCV infection and 67 subjects with HIV/HCV co-infection were enrolled. Serum was assessed for detectable cryoglobulins, liver enzymes, HCV viral load and HCV genotypes. In HIV positive patients, plasma HIV RNA and CD4+ cell count were determined. A chi-square test was used to compare the prevalence of cryoglobulins in our two categories of patients. Cryoglobulinemia was detected in 14/58 HCV mono-infected patients (24.1%) and in 10/67 HCV/HIV co-infected patients (14.9%), without any significant statistical difference between the two groups (p=0.2). Only two HCV mono-infected patients complained of arthralgia. No significant correlation was found between the presence of cryoglobulinemia and ALT levels, HCV viremia and duration of HCV infection. In HIV patients circulating cryoglobulins were not correlated with plasma HIV viral load, CD4 cell count and with duration of HIV infection. In conclusion, mixed cryoglobulinemia may be detected in a similar rate in the two groups and HIV infection does not appear to play a significant role in cryoglobulin production.

Crimean-Congo hemorrhagic fever is a tick-borne viral disease reported from more than 30 countries in Africa, Asia, South-East Europe, and the Middle East. The majority of human cases are workers in livestock industry, agriculture, slaughterhouses, and veterinary practice. Nosocomial transmission is also well described. Clinical manifestations are nonspecific and symptoms typically include high fever, headache, malaise, arthralgia, myalgia, nausea, abdominal pain, and nonbloody diarrhea. Patients may show signs of progressive hemorrhagic diathesis. Laboratory abnormalities may include anemia, leukopenia, thrombocytopenia, increased AST/ALT levels, and prolonged prothrombin, bleeding, and activated partial thromboplastin times. Diagnostic methods include antibody detection by enzyme-linked immunosorbent assay, virus isolation, antigen detection, and polymerase chain reaction. The mainstay of treatment of Crimean-Congo hemorrhagic fever is supportive, with careful maintenance of fluid and electrolyte balance, circulatory volume, and blood pressure. The Crimean-Congo hemorrhagic fever virus is susceptible to ribavirin in vitro. There is no controlled study evaluating oral versus intravenous ribavirin in treating Crimean-Congo hemorrhagic fever patients, but few studies have evaluated oral ribavirin. This article reviews the epidemiology, pathogenesis, clinical manifestations, diagnosis, treatment, prevention, and prognosis of Crimean-Congo hemorrhagic fever with a special focus on oral ribavirin as a choice of medical treatment.

Interferon-alpha-n1 (lymphoblastoid interferon-alpha) is a nonrecombinant 'natural' interferon derived from lymphoblastoid cells exposed to Sendai virus. In common with endogenous and recombinant interferon-alpha molecules, interferon-alpha-n1 has antiviral, immunomodulatory and antiproliferative properties. Interferon-alpha-n1 shows some efficacy in immunocompetent adults with well-compensated chronic viral hepatitis B. Rates of complete virological response (defined as an absence of detectable hepatitis B virus-DNA in the serum) ranged from 5 to 79% of adults who received various dosage regimens of interferon-alpha-n1 in monotherapy trials. Clearance of hepatitis B 'e' antigen was reported in 5 to 70% of patients treated with the drug. Spontaneous virological responses occurred in 0 to 48% of untreated patients. The clinical efficacy of interferon-alpha-n1 in patients with chronic hepatitis B is not improved by concomitantly administered deflazacort, zidovudine or levamisole, but may be increased by a course of corticosteroid pretreatment in some patients. Interferon-alpha-n1 also shows therapeutic benefit in adults with chronic hepatitis C. Complete biochemical responses (defined as normalisation of serum ALT levels) were achieved in 27 to 60% of adult patients treated with the drug, whereas spontaneous normalisation of serum ALT levels occurred in up to 11% of untreated patients. Responses to interferon-alpha-n1 were temporary in 27 to 78% of treatment responders but were sustained in 6 to 40% of patients. Emerging data delineating baseline factors predictive of a positive response to interferon-alpha-n1 treatment may aid in the selection of patients with hepatitis B or C most likely to benefit from treatment with this drug. Most patients receiving interferon-alpha-n1 experience a transient 'influenza-like' syndrome during the first week of treatment. The syndrome, which is dose related and alleviated by paracetamol (acetaminophen), is characterised by fever, chills, and arthralgia. Dose-limiting adverse effects occurring during longer term interferon-alpha-n1 therapy include fatigue, myalgia, headache, depression, pruritus and seizures. Neutropenia and thrombocytopenia may also occur during interferon-alpha-n1 treatment. Autoimmune thyroid disease may develop in up to 9% of patients treated with interferon-alpha-n1 for >or=6 months. At present, interferon-alpha-n1 and the recombinant forms of interferon-alpha are the only drugs available for the treatment of adults with well-compensated hepatitis B or C. Interferon-alpha-n1 produces moderate response rates in adults with well-compensated chronic hepatitis B or C. Thus, it is positioned alongside recombinant interferon-alpha products as a useful first-line treatment option for patients with chronic hepatitis B or C.
