Treatment of adults with autoimmune thrombocytopenic purpura (AITP) is based more on individual experience than on results of controlled studies. We compared intravenous immunoglobulin with high-dose methylprednisolone in untreated adults with severe AITP and assessed efficacy of subsequent oral steroids compared with placebo. Primary outcome was number of days with platelet count greater than 50 x 10(9)/L within the first 21 days.
We did a randomised multicentre trial based on a 232 design. 122 adults with severe AITP (platelet count < or =20 x 10(9)/L) were randomly assigned to receive either intravenous immunoglobulin or high-dose methylprednisolone on days 1-3 (randomisation A), and then to receive either oral prednisone or placebo (randomisation B) on days 4-21. Analysis was by intention to treat.
Six patients were excluded from the analysis. The number of days on which platelet counts were above 50 x 10(9)/L was 18 in 56 patients receiving intravenous immunoglobulin and 14 in 60 receiving high-dose methylprednisolone (p=0.02). Percentage of patients who had platelet counts over 50 x 10(9)/L on days 2 and 5 was 7% and 79%, respectively, in the intravenous immunoglobulin group compared with 2% and 60%, respectively, in the high-dose methylprednisolone group (p=0.04). During the second treatment period, prednisone was more effective than placebo for all short-term endpoints. Patients who received intravenous immunoglobulin and prednisone had platelet count greater than 50 x 10(9)/L for 18.5 days (p=0.005), and those treated with high-dose methylprednisolone and prednisone had this count for 17.5 days.
Intravenous immunoglobulin and oral prednisone seems to be more effective than high-dose methylprednisolone and oral prednisone in adults with severe AITP, although the latter treatment is effective and well tolerated.

- "ITP treatment usually consists of corticosteroids (CS) as a first-line approach . Patients intolerant or with contraindications to steroids, are treated with intravenous immunoglobulin (IVIg), and anti-D immunoglobulin (anti-D) , either alone or in combination . SPL is frequently recommended as a second-line therapy and results in sustained remission for nearly two-thirds of treated patients [1,12]. "

ABSTRACT: Chronic immune thrombocytopenia (ITP) is a debilitating autoimmune disorder that causes a reduction in blood platelets and increased risk of bleeding. ITP is currently managed with various pharmacologic therapies and splenectomy.This study was conducted to assess patient perceived and reported treatment side effects, as well as the perceived burden or bother, and need to reduce or stop treatment, associated with these side effects among adult patients with chronic ITP.
A Web-enabled survey was administered to members of a US-based ITP patient support group. Patients reported demographic and clinical characteristics, ITP treatments' side effects for treatments received since diagnosed, level of bother (or distress), and need to reduce or stop treatment, associated with side effects. Current and past exposure was assessed for five specific treatment types: corticosteroids (CS), intravenous immunoglobulin (IVIg), anti-D immunoglobulin (anti-D), rituximab (RT), and splenectomy (SPL), as well as for other patient-referenced therapies (captured as "other").
The survey was completed by 589 patients; 78% female, 89% white, mean age 48 years (SD = 14.71), and 68% reported a typical low platelet count of < 50,000/μL. Current or past treatment with CS was reported by 92% (n = 542) of patients, 56% (n = 322) for IVIg, 36% (n = 209) for anti-D, 36% (n = 213) for RT, and 39% (n = 227) for SPL. A substantial proportion of CS-treated patients reported side effects (98%, P < 0.05), were highly bothered by their side effects (53.1%, P < 0.05), and reported the need to stop or reduce treatment due to side effects (37.8%, P < 0.05). Among patients reporting side effects of treatment, significant associations were noted for the number of side effects, aggregate bother of reported side effects, and the need to stop or reduce treatment (all P < 0.05).
Current ITP treatments, particularly corticosteroids, are associated with multiple bothersome side effects that may lead to patients stopping or reducing therapy. Open, informed and complete communication between clinician and patient regarding both the benefits and the side effects of ITP treatment may better prepare patients for their prescribed regimens.

- "In adults, ITP usually has a chronic course, with duration over 6 months. In these cases, the ability of Ig in raising platelet counts is well documented.(12) Ig use in ITP adults can be indicated as first line therapy or as second choice therapy, as long as the treatment is indicated (platelet count below 30,000/mm3 or bleeding).(13) "

ABSTRACT: Human immunoglobulin is the most used blood product in the clinical practice. Immunoglobulin applications have increased quickly since the elucidation of its immunomodulatory and antiinflammatory properties which turned this blood product into a precious tool in the treatment of numerous diseases that present with humoral immune deficiency or that cause immune system dysfunction. Currently, the approved indications for Ig are: primary immunodeficiencies, secondary immunodeficiencies (multiple myeloma or chronic lymphoid leukemia), Kawasaki syndrome, immune thrombocytopenic purpura, Guillain Barré syndrome, graft-versus-host disease following bone marrow transplantation and repeat infections in HIV children. On the other hand, there are numerous "off-label" indications of immunoglobulin, which represent 20-60% of all clinical applications of this drug. It is important to study all these indications and, above all, the scientific evidence for its use, in order to provide patients with a new therapeutic option without burdening the health system. This review results from a wide selection of papers identified in the Pubmed and Lilacs scientific electronic databases. A group of descriptors were used from human immunoglobulin to the names of each disease that immunoglobulin is clinically applied. Our main objective is to list the numerous indications of immunoglobulin, both authorized and "off-label" and to analyze these indications in the light of the most recent scientific evidence.

ABSTRACT: Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder in which platelets are opsonised by autoantibodies and destroyed by macrophages. Therefore, ITP represents a prototype of a B-cell-mediated autoimmune disorder. B-cell activating factor (BAFF) is a member of the tumour necrosis factor family and an important regulator of B-cell development. BAFF levels were determined in serum samples from 53 patients with ITP. Serum BAFF levels in patients with an active ITP were increased when compared with the healthy control group (median 1620 pg/ml vs. 977 pg/ml; P < 0.001). Moreover, immunosuppressive treatment was associated with strongly suppressed BAFF levels (median 629 pg/ml; P < 0.01). In addition, a polymorphic site was detected in the BAFF promoter region (-871) that appeared to occur more frequently in ITP patients than in healthy persons. This promoter variant was associated with very high BAFF levels in ITP patients. Our data suggest that BAFF is an important pathogenetic factor in the development of ITP.
