Fecal Microbiota Transplantation for Refractory IgA Nephropathy

IgA Nephropathy

IgA nephropathy (IgAN) is one of the most common glomerular diseases worldwide. Current treatments for IgAN are limited by their relatively insufficient efficacy and severe adverse events. Previous studies suggested that the disorder of intestinal flora may play an important role in the pathogenesis and prognosis of IgAN. Fecal microbiota transplantation (FMT) have been proved to be effective on rebuilding the intestinal microecological balance. However, there is no evidence for the safety and efficacy of FMT in IgAN. Therefore, investigators perform a prospective cohort study to evaluate the safety and efficacy of FMT in IgAN patients who did not response to the conventional treatment and did not want to aggravate immunosuppressive treatments or IgAN patients who did not response to immunosuppressive treatments.

Hydroxychloroquine Sulfate Alleviates Persistent Proteinuria in IgA Nephropathy

Primary IgA Nephropathy

Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis in the world.There is to date no curative therapy for patients with IgAN.It is considered that dendritic cells, Toll-like receptor (TLR) 9 and cytokines interleukin-6 (IL-6), and interferon-alpha (IFN-a) and tumor necrosis factor-alpha (TNF-α), play an important role in the aberrant mucosal response. Hydroxychloroquine is an antimalarial agent and had a notable impact on immune activation by the reduction of circulating activated immune cells that including decreased TLR-expressing cells, reduced IFN-secreting plasmacytoid dendritic cells, reduced production of inflammatory cytokines including interferon alpha, IL-6 and TNF alpha. Recent studies showed hydroxychloroquine had a benefit for renal remission and could retard the onset of renal damage in patients with lupus nephritis. hydroxychloroquine may have the potential effect in IgA nephropathy, alleviated the proteinuria and had the renal protect effect. This will be a single center, prospective, randomized, controlled study to assess the utility of hydroxychloroquine in IgAN patients.

Effect of Immunosuppression in IgA Nephropathy

Biopsy-proven IgA Nephropathy

IgA nephropathy (IgAN) is the most common glomerulonephritis worldwide, leading to end stage renal disease (ESRD) in up to 30 to 40% of patients with in a few decades after diagnosis. Several therapeutic options have been used in clinical practice. However, no treatments can completely stop the progression of IgAN. Given the pathogenic mechanism of IgAN, many researchers have tried to treat patients with IgAN using immunosuppression such as corticosteroids. To date, there have been conflicting results on the effects of immunosuppression in IgAN. Earlier studies from Italian groups showed that corticosteroid treatment significantly attenuated kidney function decline and decreased the development of ESRD. Since then, the beneficial effects of corticosteroids have generally been accepted for treatment of IgAN particularly in patients with high degree of proteinuria > 1.0 g/day despite maximal conservative care during 3 to 6 months. However, a recent interventional study by German group, known as the Supportive Versus Immunosuppressive Therapy for the Treatment of Progressive IgA Nephropathy (STOP-IgAN) trial, showed that immunosuppressive treatment in addition to intensive supportive care did not significantly improve renal outcome and resulted in more treatment-related side effects. Moreover, the Therapeutic Evaluation of Steroids in IgA Nephropathy Global (TESTING) study, another randomized controlled study from China, was early terminated because of safety concern related to corticosteroids. Interestingly, the primary composite outcome occurred significantly less in the methylprednisolone group as compared to the placebo group despite more serious adverse events in the former group. With this background in mind, we designed a multicenter prospective randomized controlled open-label trial; a step-wise therapeutic approach with corticosteroids or add-on cyclophosphamide therapy in IgAN patients with persistent proteinuria who have preserved eGFR of ≥ 30 ml/min/1.73 m2. A total of 19 hospitals will participate in this study. During 12 weeks before the enrollment, all patients will receive maximal supportive care including the use of RAS blockers, blood pressure control with a target of <130/80 mmHg, and protein restriction diet. If proteinuria does not decrease < 1.0 g/g creatinine, patients will be randomly assigned to continue supportive care, or to receive corticosteroids. At 3 months after randomization, patients in the corticosteroid arm who have persistent proteinuria of ≥ 1.0 g/g creatinine, or fast decline in eGFR ≥ 15% from the baseline value, will additionally receive cyclosphosphamide during the following 3 months. Patients who have substantial decreased amount of proteinuria < 1.0 g/g creatinine at 3 months will continue protocol-based corticosteroids during the same period. At 6 months after randomization, patients who receive add-on cyclophosphamide will switch to azathioprine as a maintenance therapy and those who receive corticosteroids alone will discontinue the treatment and will be followed up during 24 months thereafter. At least 87 subjects (a total of 174) would be required for each group to detect 13.5% difference in response rates between the two groups based on previous studies if type I error rate is 5% and type II error is 20% given 20% of drop-out rate during the study period. The primary endpoint is the development of a ≥ 30% decline in eGFR from the baseline or the onset of ESRD. This study will unveil conflicting results on the effects of immunosuppressive treatment in IgAN patients at high risk of progression.

Rituximab in Recurrent IgA Nephropathy

Recurrent IgA Nephropathy

Currently, the treatment options of recurrent IgA nephropathy (IgAN) are conflicting and largely based on expert opinions. Consequently, the recent KDIGO clinical practice guideline for the care of kidney transplant recipients has concluded that there are no definite strategies for prevention and treatment. However, recurrent IgAN in the transplanted kidney is common and may contribute to graft loss, in particular, if cresentic formation, extra- or endocapillary proliferation were presented in kidney pathology. Herein, the investigators assume that rituximab, anti-CD20 Ab agent, can reduce circulating IgA with subsequently decrease rate of polymeric forms of IgA deposition in glomerular capillaries. Therefore, the investigators speculate that rituximab may have potential effect to reduce circulating polymeric forms of IgA and slow progression of recurrent IgAN.
