After receiving Rituxan, some people have developed low levels of certain antibodies in their blood for a long period ...

What are the diseases treated with immunosuppressants?
This helps reduce the impact of the autoimmune disease on the body. Autoimmune diseases treated with immunosuppressant drugs include: psoriasis . lupus. rheumatoid arthritis. Crohn’s disease. multiple sclerosis. alopecia areata.
What is the purpose of immunosuppressant drugs?
Immunosuppressant drugs are a class of drugs that suppress, or reduce, the strength of the body’s immune system. Some of these drugs are used to make the body less likely to reject a transplanted organ, such as a liver, heart, or kidney. These drugs are called antirejection drugs.
Why do people need immunosuppressants for transplants?
This is because your immune system sees a transplanted organ as a foreign object. As a result, your immune system attacks the organ as it would attack any foreign cell.
How do immunosuppressants affect the immune system?
Immunosuppressant drugs weaken your immune system to reduce your body’s reaction to the foreign organ. The drugs allow the transplanted organ to remain healthy and free from damage.
Why are immunosuppressants used?
Autoimmune conditions. Immunosuppressant drugs are used to treat autoimmune diseases. With an autoimmune disease, the immune system attacks the body’s own tissue. Because immunosuppressant drugs weaken the immune system, they suppress this reaction.
What happens when immunosuppressant drugs weaken your immune system?
When an immunosuppressant drug weakens your immune system, your body becomes less resistant to infection. That means they make you more likely to get infections. It also means that any infections get will be harder to treat. If you have any of these symptoms of infection, call your doctor right away: fever or chills.
What is the goal of immunosuppressant therapy?
The goal of immunosuppressant therapy is to find the treatment plan that will suppress your immune system while having the fewest, least harmful side effects.
What is RTX antibody?
Rituximab (RTX) is a monoclonal antibody (IgG1k) that specifically targets the transmembrane protein CD20 expressed on pre-B and mature B lymphocytes [ 1, 2, 3 ]. Binding of RTX to its receptor results in significant depletion of B-cells in lymphoid tissues and peripheral blood by different mechanisms, including apoptosis, complement-dependent cytotoxicity, and antibody-dependent cytotoxicity [ 4, 5, 6 ]. Since hematopoietic stem cells do not express CD20, one course of treatment with rituximab is followed by B-cell repopulation of the peripheral blood starting usually within 6 to 9 months [ 7 ]. However, a subset of RTX-treated subjects develop prolonged B-cell deficiency and severe hypogammaglobulinemia requiring long-life immunoglobulin replacement [ 8, 9, 10 ].
What is the most common autoimmune disease in CVID?
Cytopenias, including immune thrombocytopenia (ITP), autoimmune hemolytic anemia (AIHA) and autoimmune neutropenia (AN), are the most common hematological autoimmune disorders in CVID [ 81 ]. Autoimmune cytopenias (AC) may be the first evidence of immune dysregulation, preceding the occurrence of recurrent infections and even of hypogammaglobulinemia [ 82 ]. In the last report from the European CVID Registry by the European Society for Immunodeficiencies (ESID), AC were found to be correlated with enteropathy, granulomatous disease, splenomegaly and splenectomy, low IgA level, and later age of onset of CVID, while had been already associated with the reduction of IgG class-switched B-cells (CD27+IgM−IgD−) in peripheral blood [ 83, 84 ]. Although the pathogenesis of AC in CVID is not completely understood, various mechanisms have been proposed: the reduction of T regulatory (Treg) cells, whose relevance is supported by the finding of high rates of both granulomatous disease and autoimmunity in the subset of CVID patients with very low Treg cells [ 85, 86 ], and the persistent antigenic exposure to microbial antigens, which could trigger autoimmunity by molecular mimicry [ 87 ]. Recently, Romberg et al. found that patients with CVID and AC displayed irregularly shaped hyperplastic germinal centers with an increase in numbers of circulating TFH cells correlating with decreased regulatory T-cell frequencies and function [ 88 ].
What is the role of polyvalent immunoglobulin in CVID?
Thanks to the successful use of polyvalent immunoglobulin replacement therapy to treat and prevent recurrent infections, non-infectious complications, including autoimmunity, polyclonal lymphoproliferation and malignancies, have progressively become the major cause of morbidity and mortality in CVID patients.
Does RTX cause apoptosis?
Moreover, RTX can cause the apoptosis of B cells through the induction of both CD20 cross-linking on surface membrane and MAP kinase activation.
Does RTX deplete B cells?
RTX depletes B cells primarily through three different mechanisms: antibody-dependent cell-mediated cytotoxicity (ADCC), complement-mediated cytotoxicity (CMC) and induction of apoptosis (Fig. 1) [ 65 ]. Among these, ADCC and CMC seem to be the most accountable for the B-cell depleting effect of RTX in vivo [ 66 ].
Is RTX safe for autoimmune disease?
Although glucocorticoids remain the first line of treatment for all the complications of CVID associated with the immune-dysregulation, over the last 5–10 years, RTX has proven to be an effective and relatively safe second-line therapy for both autoimmune and non-malignant lymphoproliferative manifestations. To date, there are no data on the long-term efficacy and side effects of RTX and other second-line therapeutic options. Further trials evaluating the head-to-head comparison between RTX and other second-line therapeutic options are needed to optimize the management strategies of non-infectious complications of CVID.
What is Rituxan?
Rituxan (rituximab) is a cancer medicine that interferes with the growth and spread of cancer cells in the body. It is also used to treat other non-cancer conditions.

Call your doctor right away if you have any of the following symptoms (which may start gradually and get worse quickly): confusion, memory problems, or other changes in your mental state; weakness on one side of your body;
What is the best treatment for rheumatoid arthritis?
Biological drugs are becoming more popular as a treatment for rheumatoid arthritis (RA). Rituximab is one such drug that works by blocking the activity of immune cells. This then reduces the high level of inflammation seen in the joints of RA patients.
What is the condition where the body's antibody levels are severely reduced?
This prolonged treatment can weaken a patient’s immune response and can lead to a condition called hypogammaglobulinemia. This is an immune disorder where the body’s antibody levels are severely reduced, which increases the risk of serious infections.
Does Rituximab affect the immune system?
This study looked at the effect of rituximab (Rituxan) treatment on the immune system in patients with rheumatoid arthritis. The authors concluded that prolonged treatment with rituximab can lower patients’ immune responses and increase the risk of serious infection.
Does rituximab increase infection?
In another study of 3595 RA patients, there was no increase in infection rates in rituximab treated patients compared to other therapies. However, this study showed a link between the severity of hypogammaglobulinemia and the risk of serious infection.
