What is the role of rituxan in the immune system?
Rituxan is an antibody that targets the protein CD20 that occurs on the surface of B-cells, which play a key role in immune response. When Rituxan binds to CD20, it triggers the destruction of the cells it attaches to. Reducing the number of mature B-cells limits their ability to promote the inflammation and joint damage that is a hallmark of RA. 3

How long does it take to retreat rituximab?
Retreatment of rituximab was given in 69% of patients between week 24 and 48 (mean time to retreatment was 8.5 months). The overall ACR responses at week 24 were similar to those reported in the REFLEX trial 29 and the clinical response was sustained with retreatment. With stratification of patients according to RF status, it was demonstrated that the clinical efficacy of rituximab was superior in RF positive than RF negative patients.
What should be done before rituximab?
Before commencement of rituximab, a detailed medical history that includes allergies, medical comorbidities, and recurrent infections should be taken and a complete physical examination should be performed to consider possible contraindications. Hepatitis B and C serologies and liver function tests should be routinely performed. Reactivation of occult hepatitis B infection (surface antigen of the hepatitis B virus [HBsAg] negative but total hepatitis B core antibody [anti-HBc] IgG positive) has been reported in the oncology literature, 80 – 82 but only several case reports were published in patients with RA treated with rituximab. 70 – 72 Thus, both HBsAg and anti-HBc IgG should be routinely obtained and hepatitis B virus (HBV) DNA titers should be determined when the latter is positive. HBsAg and anti-HBc IgG negativity identifies those who require vaccination before rituximab therapy, whereas HBsAg positive patients and/or anti-HBc positivity should be treated prophylactically. However, in our locality, we do not generally recommend using rituximab in patients who are hepatitis B carriers (HBsAg positive) unless there are absolutely no alternatives and close monitoring by the hepatologists after appropriate antiviral therapy is available. The management of occult hepatitis B infection in rituximab users remains unclear. HBsAg negative but anti-HBc positive patients with undetectable HBV DNA titers are not contraindicated to rituximab. Close monitoring to detect a rise of HBV DNA is mandatory and prophylactic antiviral treatment should be considered with the opinion of hepatologists. Patients with elevated HBV DNA titers should be referred to hepatologists for antiviral treatment.
What are the factors that contribute to the pathogenesis of rheumatoid arthritis?
The pathogenesis of rheumatoid arthritis (RA) remains enigmatic. Multiple genetic and environmental factors are likely to be involved in the susceptibility to RA development. 1 The discovery of the rheumatoid factor (RF) in the 1940s and the abundance of plasma cells and activated B lymphocytes in the RA synovium emphasized the importance of B cells in the pathogenesis of the disease. 2 However, work on B cells and autoantibodies waned over time when it was demonstrated that RF lacked sensitivity and specificity. Attention was shifted to other players of the immune system such as T cells, macrophages, dendritic cells, and fibroblasts. 3 Revival of interest in the B cell pathogenesis of RA was related to the discovery of autoantibodies that direct against citrullinated peptides. 4 Moreover, the success of B cell depletion therapy in the treatment of RA in the past decade has led to a renaissance of B cells as key mediators of RA. 5
How often should I give Rituximab?
In clinical studies, rituximab was given per protocol at baseline and then every 6 months. 27, 28, 30 Clinical response is typically observed 3–4 months after the first course of rituximab. However, the durability of the clinical response is variable and often unpredictable in different patients. A prospective study showed that the mean time for rituximab retreatment since baseline was around 8.5 months in anti-TNF failure RA patients. 34 The rituximab insert package in the US states that retreatment can be given every 6 months according to clinical evaluation, but not sooner than every 4 months. 5 The latest European consensus statements on use of rituximab in RA suggested that retreatment of rituximab might be considered after at least 24 weeks in patients who did not achieve clinical remission or at least low disease activity state as evidenced by any disease activity index. 44 Otherwise, retreatment should be delayed until disease activity returned.
How long does it take for B cells to repopulate after rituximab?
Repopulation of the peripheral blood B cells usually occurs at 6–9 months after rituximab administration, and the time to reconstitution of the peripheral B cells depends on the clearance of the compound and the regenerative capacity of the bone marrow. 17 Peripheral blood B cell repopulation after rituximab treatment is similar to what is observed after bone marrow transplantation, and predominantly involves a subset of naïve or antigenically inexperienced transitional B cells derived from an immature population. 18 The degree of B cell depletion in the peripheral blood and synovium has been correlated positively with the clinical response of rituximab. 19, 20 Despite the fact that rituximab does not deplete fully matured plasma cells, repeated administration of the biologic frequently induces a reduction of immunoglobulins, particularly immunoglobulin G (IgG), which may carry an increased risk of infection. 21
When was Rituximab first used?
The efficacy of rituximab in RA was first reported in 1998 by a group of UK investigators in an open-label trial, 22 followed by confirmation by other case series. 23, 24 Subsequently, eight randomized controlled trials (RCTs) were conducted in patients with RA ( Table 1 ). 25 – 32
Does Rituximab slow radiological progression?
In early RA patients, a higher dose of rituximab (two doses of 1,000 mg) in combination with MTX showed a better efficacy in halting radiological progression than a lower dose of rituximab (two doses of 500 mg) when compared to MTX alone, although a lower dose of rituximab itself was associated with a significant difference in progression of radiological damage compared with placebo. 31, 36 As erosion occurs early in the course of the disease, 43 prevention of radiological progression with the use of a higher dose of rituximab seems to be logical in patients with early RA. In patients who are refractory to the anti-TNF biologics, a lower dose of rituximab (two doses of 500 mg) has not been tested for radiological progression, whereas efficacy in slowing radiological damage has been shown with the higher dosing regimen (two doses of 1,000 mg). 33

Before the first Rituxan infusion
My first Rituxan infusion, which took about seven hours, was on March 22, 2017. Before getting the infusion, I had read and heard some things about the drug that made me really anxious about starting it. I had never been that nervous about beginning any of the other several infusions (or injections) I've had since 2003, but I was with this one.
Rituxan side effects
Well, the "bullet" finally hit me during my first Rituxan infusion. About only 30-45 minutes into the infusion my throat suddenly started feeling weird. And by "weird" I mean kind of itchy but also oddly tight, like I had a lump in there and it was harder to swallow.
