In the cases where the culture is negative, it can be difficult to differantiate tuberculosis from Crohn's disease based on both the clinical and histological features.When side effects of classic antimycobacteria are encountered,we can initially add ciprofloxacin to the treatment of tuberculosis. We reported a case of 19-yr-old patient, who was treated as Crohn's disease and worsen. We began to tuberculosis treatment, and the patient improved clinically and histologically. The main point in this case is that widespread involvement of gastrointestinal tract can be brought about by non resistant strains of Mycobacterium tuberculosis even in immunocompetent patients.展开更多

Hence, in addition to reducing the long-term side- effects of therapeutics for all leukemia patients, there is an urgent need for novel therapeutic strategies for difficult-to-treat leukemia cases. Due to the cytotoxicity of drugs, the major challenge currently is to deliver the therapeutic agents to neoplastic cells while preserving the viability of non-malignant ceils. In this study, we propose a therapeutic approach in which high doses of hydroxychloroquine and chlorambucil were loaded into biodegradable polymeric nanopartides coated with an anti-CD20 antibody.We first demonstrated the ability of the nanoparticles to target and internalize in tumor B-cells. Moreover, these nanoparticles could kill not only p53-mutated]deleted leukemia cells expressing a low amount of CD20, but also circulating primary ceils isolated from chronic lymphocytic leukemia patients. The safety of these nanoparticles was also demonstrated in healthy mice, and their therapeutic effects were shown in a new model of aggressive leukemia. These results showed that anti-CD20 nanoparticles containing hydroxychloroquine and chlorambucil can be effective in controlling aggressive leukemia and provided a rationale for adopting this approach for the treatment of other B-cell disorders.展开更多
