Active clinical trials for "Immune System Diseases"

Cancer is the leading cause of death in man and the second leading cause in women with 85,000 and 63,000 deaths, respectively, in 2012. A working group led by Holly L. Howe, PhD, in 2002 defined primary neoplasia Such as the occurrence and diagnosis of two or more independent neoplasms of different histology in the same patient. The occurrence of a new cancer has become more frequent in recent years: the prevalence of multiple primary neoplasia (NPM) is estimated between 0.73% and 11.7%. According to the French data, the risk of second cancer in people who have already had a first cancer is increased by 36% compared to the general population. Several studies have reported an increase in the risk of cancer after treatment of lymphoma but there are currently no studies on the occurrence of lymphoma and cancer of synchronous occurrence. In our department, 19 patients presented cancer and lymphoma synchronously, that is to say 6 months between 2007 and 2012. The main objective is to show that there is an increase in the incidence of cancers in patients diagnosed for lymphoma synchronously. Secondary objectives are to describe the clinical and biological characteristics of the patients concerned and to formulate hypotheses on the physiopathological mechanisms involved: peri-tumoral B-cell lymphoproliferation, alteration of the immune system or rearrangement of the BCR. In a second step, the investigator could propose a multicenter epidemiological study using data from the different Cancer Registries. If results are confirmed in a larger cohort, recommendations could be made.

Assessment of quality of life of patient with chronic idiopathic thrombocytopenic purpura according to the type of treatment

Systemic lupus erythematosus , the archetypal multisystem autoimmune disease, presents many diagnostic and management challenges. One such challenge is the excess cardiovascular disease observed in patients with Systemic lupus erythematosus . Coronary heart disease and other manifestations of atherosclerosis continue to be a major cause of death in patients with Systemic lupus erythematosus.Regulatory B-cells have been identified as a negative regulator of the immune system that inhibit pathological immune response by suppressing both uncontrolled protective immune response and damaging autoimmune responses

Immature platelets-also termed reticulated platelets (RP)-are platelets newly released into the circulation, and have been associated with a variety of pathological bleeding events including primary immune thrombocytopenia (ITP). They can be assessed by flow cytometry (FCM) after staining with thiazole orange (TO) at low concentration and expressed as a fraction of the total platelet count (RP%). The diagnosis of primary ITP is based on differential diagnosis and the measurement of RP% can serve as an alternative diagnostic test that are useful in daily practice. Our study aimed at distinguishing primary ITP from other thrombocytopenic disorders, especially aplstic (hypoplastic) or chemotherapy-induced thrombocytopenia by FCM. The sensitivity and specificity of the assay as well as agreement between RP% measurement and monoclonal antibody-specific immobilization of platelet antigen (MAIPA) were analyzed accordingly.

Gastric low-grade mucosa-associated lymphoid tissue lymphoma (MALToma) is associated with Helicobacter pylori (HP) infection, and around 70% of these tumors can be cured by HP eradication therapy (HPE). However, the role of antibiotics in the frontline treatment of extragastric MALToma remains unclear. In addition to anecdotal case reports showing histologic regression of extragastric MALTomas after antibiotics, our explorative study found that frontline HPE (clarithromycin, amoxicillin, and omeprazole) resulted in complete remission (CR) in this subgroup patients (2 salivary gland, 1 lung, 1 colon, and 4 ocular adnexal MALToma [OAML]). Interestingly, two patients with OAML who do not respond to Chlamydia psittaci (CP) eradication using doxycycline achieved CR after HPE. These findings suggest that bacterial infections, including HP, may be involved in the lymphomagenesis of these extragastric MALTomas. Our preliminary results also revealed that 5 (23.8%) of 21 HP-negative gastric MALToma patients achieved CR after HPE, indicating that antibiotics may also have ability to eradicate non-HP bacteria. Based on our preliminary findings and the indolent biologic behavior of MALToma, it is reasonable to use frontline HPE in the treatment of early-stage low-grade extragastric MALToma.

This study is a multicenter and prospective cohort study of children diagnosed with asthma. Clinical symptoms and signs, quality of life, blood test, and lung function were detected every three months. FeNO detection, chest imaging, and induced sputum smear were detected when necessary. Biological samples will be collected when recruiting and finishing follow-up.

Outcome of Hodgkin lymphoma patients over than 60 years treated by chemotherapy and/or radiotherapy: retrospective analysis.

The autograft of patients with prognostically unfavourable B-cells lymphoma cells in first remission remains controversial, in particular since the association of Rituximab with chemotherapy. Even though many randomized and non-randomized studies have been conducted, their is still no standard procedure . Recently, the use of early TEP (positron emission topography) answer, after 2 in 3 cures of chemotherapy allowed to select the poor-responder patients who remain candidate to autograft in front-line. Nevertheless, in good-responder patients, the benefits of an intensification therapy ins term of long-lasting disease control remains discussion. This institutional retrospective study aims at comparing the outcome of early metabolic responder patients who received an intensification treatment to those who received a standard chemotherapy.

Extension of patient follow-up of the IFM/DFCI 2009 study over a period of 4 years (that is, from 01 December 2016 to 30 November 2020) during which patients will be followed up in the normal course of care and according to the usual care of the centers, with collection of the needed data about twice a year by the investigators

Ocrelizumab is FDA approved for therapy of multiple sclerosis (MS). It depletes B cells and stops MS inflammation.
