Active clinical trials for "Immune System Diseases"

300 IgG4-RD patients, 200 other autoimmune diseases, 60 IgG4-RD mimickers and 100 healthy controls were enrolled. Circulating plasmablast/plasma cells were detected of all patients at baseline and healthy controls. IgG4-RD patients were followed up every 3-6 months. Circulating plasmablast/plasma cells were also detected at disease remission and relapse. IgG4-RD patients' clinical data and laboratory parameters were collected.

At this moment, the duration of the treatment in Proliferative Lupus Nephritis has not been determined. Almost 30 percent of patients in total remission during or after a treatment, will relapse in the first 5 years. The factors associated to Renal relapses are not completly known. The investigators think that an histological control study performed to patient with complete remission for a year at the end of a 3 years treatment could help us to know which patients are going to relapse.

Our aim is to establish multi-center national Egyptian database of information for inherited and acquired neuromuscular diseases in infants and children from 0 to 18 years of age.

There is a group of patients with rheumatoid arthritis (RA) that suffer from chronically painless synovitis in the hands. The objective of this study is to compare painless synovitis with painful synovitis according to the sonographic (Gray-scale and power Doppler) findings. A sonographic examination (Gray-scale and power Doppler) will be done to evaluate metacarpophalangeal joints of patients without local painful and will be a comparison with patients with local painful.

Atopic dermatitis is a common disease which affects about one million people in Finland at some stage of their life. In atopic dermatitis we see a superficial inflammation of the skin and a defect in skin barrier function. The filaggrin protein plays a central role in the skin barrier function and studies indicate that about 30% of patients with atopic dermatitis have a mutation in the filaggrin gene. The aim of the study is to investigate whether a mutation in the filaggrin gene affects the clinical treatment outcome in patients with atopic dermatitis. If a mutation predisposes to a worse response to treatment, this could be examined and those patients with the mutation could be given extra treatment support for their atopic dermatitis. The prevalence of filaggrin mutation in the Finnish non-atopic population is studied in the control group.

Platelets are blood cells that are important in coagulation of the blood. These cells have recently been shown to play a role in a number of other biologic processes, for example inflammation. In this study the investigators will determine the extent of platelet activation in people suffering from common chronic skin inflammation-urticaria and allergic dermatitis.

This study provides for the collection of a series composed by patients with newly diagnosed of acute lymphoblastic leukemia in the period 1999-2011. This collection is carried out with retrospective investigation, through the review of paper and electronic records and data cards in large part already collected as part of study protocols "GIMEMA" or "BFM" or "NILG" approved by the Ethics Committee of Hospital. The purpose of data collection is to check with retrospective predictability of classical risk factors in relation to disease response, and overall survival of the event-free survival, to estimate the cumulative incidence of competitive events such as the emergence of disease, acute and chronic transplant, the transplant-related mortality and relapse of disease.

An prospective / retrospective multicenter observational study whose objectives are to understand the interactions between hepatitis c virus and Non Hodgkin lymphomas. The characteristics , evolution and treatment of diseases will be observed from the study.

1000 women with infertility who are already decided to be treated with ICSI will be subjected to full history taking and clinical examination. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol will be assessed and the antral follicular count (AFC) will be assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm. All patients will have standard pituitary down-regulation followed by (Human menopausal gonadotrophin (HMG) stimulation until the day of (Human chorionic gonadotrophin (HCG) administration. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe and the Preovulatory follicle count (PC) will be assessed, (PFC) is defined as number of follicles measuring≥16mm. Follicular sensitivity index (FSI) will be calculated as: (FSI =PFC*10000/AFC*Total dose of FSH)

The following is the investigators hypothesis regarding the pruritus of BP patients during remission. Anti-BP 180 IgE binds to dermal mast cells, inducing their activation and secretion of mediators after being cross-linked by antigens. Among mediators, histamine directly induces itching and vessel changes, whereas tryptase potentiates itching and vessel changes in an indirect way through the actions of neuropeptides. Tryptase stimulates neurons which in turn secrete neuropeptides.
