Tumour necrosis factor alpha (TNFalpha) has a central role in the host immune response to mycobacterial infection.TNFalpha blockade may therefore result in reactivation of recent or remotely acquired infection. In reported mycobacterium tuberculosis infections, extra-pulmonary and disseminated tuberculosis (TB) was common, appeared rapidly, and if unrecognized, with fatal outcome. We present a female patient with miliary TB following treatment with infliximab for fistulizing Crohn's disease. Five years before admission, the patient was diagnosed with Crohn's disease, with inflammation limited to the terminal ileum and sigmoid colon and has been on azathioprine 100 mg/day for the last 10 months. Three months before admission to the hospital she developed an enterocutaneous fistula for which therapy with infliximab was started in addition to azathioprine therapy. A tuberculin skin test and a chest x-ray were performed prior to the first infusion with normal findings. She presented with a 6-week history of fever, weakness, weight-loss and a 2-week dry cough. Chest x-ray and computed tomography displayed remarkable bilateral hilar and mediastinal lymphadenopathy and uniformly distributed fine nodules throughout both lung fields varying in size from 2 to 3 mm, without any signs of cavitation. Since there were clinical and morphological signs that indicated miliary TB, the treatment with antituberculous therapy was started and six weeks later all of the symptoms completely resolved and the lesions visible on x-ray diminished. The clinical use of TNF-inhibitors is associated with increased risk of developing tuberculosis. Physicians should be aware of the increased risk of reactivation of TB among patients treated with anti-TNF agents and regularly look for usual and unusual symptoms of TB.

Introduction The triple therapy which consists of one of the protease inhibitor plus pegylated interferon and ribavirin (P/R) is the standard of care for the treatment of chronic hepatitis C virus (HCV) genotype 1(G1) infection both in treatment-naive and experienced patients. Objective The aim of this study was to analyze the efficacy and tolerability of this regime in hospital practice in Serbia. Methods From July 2012 to October 2012, 20 previously treated patients with advanced fibrosis and HCV G1 infection were included in the triple antiviral regimen in six referral centers in Serbia. All patients were treated with response guide therapy (RGT) regime according to the boceprevir treatment protocol. During the 4-week lead-in period all patients received peginterferon plus ribavirin. After the lead-in period boceprevir was added in the dosage of 800 mg three times a day orally. The subsequent treatment varied according to virologic response and fibrosis. During the therapy HCV RNA level was measured at week 4, 8, 12, 24 of the treatment for the assessment of virologic response profile. All patients who completed therapy were assessed at the end of the treatment and at the end of an additional 24-week treatment-free period for a sustained virologic response (SVR). Results The total of 20 patients with advanced fibrosis was treated. Among patients with an undetectable HCV RNA level at week 8 the rate of SVR was 100%. No patient with decrease in the HCV RNA level <1 log 10 IU/ml at treatment week 4 achieved SVR. The overall rate of SVR was 55%. The safety profile of the treatment regimen was good. Anemia was reported in 25% of patients. There was no life-threatening treatment adverse event. Conclusion Boceprevir in combination with P/R achieved fairly good SVR rates in patients that were "most difficult to treat" who failed on dual therapy and was effective among patients with cirrhosis. © 2015 Serbia Medical Society.

Introduction. There is a rise of visceral leishmaniasis in immunocompromised patients due to increased availability of immunomodulatory drugs. In order to point at the occurrence of visceral leishmaniasis in patients with inflammatory bowel disease (IBD), we reported a case of female patient with a travel history to European Mediterranean countries, who was on immunosuppressive treatment due to ulcerative colitis. Case report. A 29-year-old female patient was admitted to hospital due to severe relapse of ulcerative colitis. Corticosteroid therapy was administered in addition to previous longterm azathioprine, with clinical response to the treatment. During the course of the disease she had recurrent high-grade fever with marked hepatosplenomegaly and pancytopenia. The diagnosis of leishmaniasis was established by positive serology tests and microscopic finding of amastigotes in bone marrow smears. The disseminated infection was responsive to treatment with liposomal amphotericin B, but therapy had to be discontinued due to urticarial rush. Subsequent therapy with antimony was administered, but it had to be stopped too due to liver toxicity. No further treatment for leishmaniasis was initiated as the clinical and laboratory data suggested that the patient had responded to the treatment. She was discharged from hospital in IBD remission and without signs of the infection. Conclusion. Visceral leishmaniasis should be considered in IBD patients with fever of unknown origin and relevant travel history in order to achieve favorable disease outcome. © 2020 Inst. Sci. inf., Univ.
