Abstract
Immunoglobulin A nephropathy is a complex autoimmune disease with various underlying causes and significant clinical heterogeneity. There are large individual differences in its development, and the etiology and pathogenesis are still poorly understood. While it is known that immunobiological factors play a significant role in the pathophysiology of immunoglobulin A nephropathy, the specific nature of these factors has yet to be fully elucidated. Numerous investigations have verified that CD4+ and CD8+ T lymphocytes are involved in the immunopathogenesis of immunoglobulin A nephropathy. Furthermore, certain data also point to γδT cells' involvement in the pathophysiology of immunoglobulin A nephropathy. By thoroughly examining the mechanisms of action of these T cells in the context of immunoglobulin A nephropathy, this review sheds light on the immunopathogenesis of the disease and its associated factors. The review is intended to provide reference value for the future research in this field and promising treatment clues for clinical patients.

Abstract
In recent years, increasing numbers of reports have described new onset or active disease flare of IgA nephropathy (IgAN) during administration of TNF-α inhibitor (TNFi) therapy for chronic inflammatory diseases. Crohn's disease (CD) is the most common indication for TNFi therapy in this clinical setting, but the underlying etiology of IgAN in such patients remains unclear. We report our experience with three patients who developed acute worsening of preexisting urinalysis abnormalities and kidney dysfunction approximately 2 to 6 years after TNFi administration for CD. Kidney biopsies at the time of kidney disease flare revealed IgAN in two patients and IgAN complicated by acute tubulointerstitial nephritis in one patient. The CD and IgAN in all three patients were successfully managed with additional corticosteroid therapy and tonsillectomy without discontinuing TNFi therapy. The clinical course of our patients and similar patients described in the literature suggests that TNFi therapy for CD is associated with a relatively high risk for new onset or disease flare of IgAN. This report discusses the possible involvement of Th1/Th2 imbalance on the immunological background of CD or IgAN.

Abstract
Extraintestinal manifestations (EIMs) are common in inflammatory bowel disease (IBD). Renal EIMs, including immunoglobulin A nephropathy (IgAN), are relatively rare. EIMs are important to consider when developing a treatment plan for IBD. Studies differ on whether IBD disease activity correlates with IgAN disease activity. Published guidance on effective therapies for IBD-associated IgAN is limited. This case report suggests that risankizumab, an effective therapy for Crohn's disease, may also be effective in treating Crohn's disease-associated IgAN.

Abstract
OBJECTIVES Secukinumab (SEC) is an effective and widely used drug in psoriatic disease and axial spondyloarthritis. However, SEC has been found to be associated with inflammatory conditions and vasculitis. These inflammatory adverse effects may complicate the treatment of underlying disease, and clinicians may experience difficulties in recognizing and managing this unusual condition. CASE REPORT A man aged 56 years with psoriatic disease refractory to conventional disease-modifying antirheumatic drugs was given adalimumab for 6 weeks, then switched to SEC when his psoriatic lesions were exacerbated. After 3 weeks of SEC treatment, he developed systemic features of IgA vasculitis while his skin lesions and arthritis persisted. CONCLUSIONS Although SEC-related inflammatory adverse events, including vasculitis, are rarely encountered in clinical practice, it is essential to recognize them because they can be mistaken as a component of the underlying inflammatory disease. In addition, the dramatic improvement in many cases after the cessation of SEC underlines the importance of making an accurate diagnosis. Pathogenetically, these adverse events are likely to be paradoxical reactions, except for SEC-induced inflammatory bowel diseases. However, in many aspects, their pathogenesis is controversial and needs clarification.

J Clin Med 2023; 12:jcm12072726. [PMID: 37048809 PMCID: PMC10094848 DOI: 10.3390/jcm12072726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 03/20/2023] [Accepted: 03/29/2023] [Indexed: 04/08/2023] Open
Abstract
Primary (pIgAN), secondary IgA nephropathy (sIgAN), and IgA-associated nephropathy can be distinguished. While pIgAN has been thoroughly studied, information about the etiology of sIgAN remains scarce. As concerns sIgAN, several studies suggest that different etiologic factors play a role and ultimately lead to a pathophysiologic process similar to that of pIgAN. In this article, we review a vast number of cases in order to determine the novel putative underlying diseases of sIgAN. Moreover, updates on the common pathophysiology of primary disorders and sIgAN are presented. We identified liver, gastrointestinal, oncological, dermatological, autoimmune, and respiratory diseases, as well as infectious, iatrogenic, and environmental factors, as triggers of sIgAN. As novel biological therapies for listed underlying diseases emerge, we suggest implementing drug-induced sIgAN as a new significant category. Clinicians should acknowledge the possibility of sIgAN progression in patients treated with TNF-α inhibitors, IL-12/IL-23-inhibitors, immune checkpoint inhibitors, CTLA-4, oral anticoagulants, thioureylene derivatives, and anti-vascular endothelial growth factor drugs.

Abstract
Renal and urinary tract complications related to inflammatory bowel disease (IBD) have been relatively understudied in the literature compared with other extraintestinal manifestations. Presentation of these renal manifestations can be subtle, and their detection is complicated by a lack of clarity regarding the optimal screening and routine monitoring of renal function in IBD patients. Urolithiasis is the most common manifestation. Penetrating Crohn's disease involving the genitourinary system as an extraintestinal complication is rare but associated with considerable morbidity. Some biologic agents used to treat IBD have been implicated in progressive renal impairment, although differentiating between drug-related side effects and deteriorating kidney function due to extraintestinal manifestations can be challenging. The most common findings on renal biopsy of IBD patients with renal injury are tubulointerstitial nephritis and IgA nephropathy, the former also being associated with drug-induced nephrotoxicity related to IBD medication. Amyloidosis, albeit rare, must be diagnosed early to reduce the chance of progression to renal failure. In this review, we evaluate the key literature relating to renal and urological involvement in IBD and emphasize the high index of suspicion required for the prompt diagnosis and treatment of these manifestations and complications, considering the potential severity and implications of acute or chronic loss of renal function. We also provide suggestions for future research priorities.

Abstract
BACKGROUND IgA nephropathy (IgAN) is the most common primary glomerulonephritis globally. Increasing evidence suggests the importance of host immunity in the development of IgAN, but its dynamics during the early stage of IgAN are still largely unclear. RESULTS Here we successfully resolved the early transcriptomic changes in immune cells of IgAN by conducting single-cell RNA-sequencing (scRNA-seq) with peripheral blood mononuclear cells. The differentially expressed genes (DEGs) between control and IgAN were predominantly enriched in NK cell-mediated cytotoxicity and cell killing pathways. Interestingly, we discovered that the number and cytotoxicity of NK cells are significantly reduced in IgAN patients, where both the number and marker genes of NK cells were negatively associated with the clinical parameters, including the levels of urine protein creatinine ratio (UPCR), serum galactose-deficient IgA1 and IgA. A distinctive B cell subset, which had suppressed NFκB signaling was predominantly in IgAN and positively associated with disease progression. Moreover, the DEGs of B cells were enriched in different viral infection pathways. Classical monocytes also significantly changed in IgAN and a monocyte subset expressing interferon-induced genes was positively associated with the clinical severity of IgAN. Finally, we identified vast dynamics in intercellular communications in IgAN. CONCLUSIONS We dissected the immune landscape of IgAN at the single-cell resolution, which provides new insights in developing novel biomarkers and immunotherapy against glomerulonephritis.

Abstract
Immunoglobulin A (IgA) nephropathy (IgAN) is the most common glomerulonephritis worldwide, characterized by IgA deposits in the glomerular mesangium. It has a progressive nature and can eventually lead to end-stage kidney failure. It can occur as a potential side effect of treatment with tumor necrosis factor alpha antagonist that has been used for numerous chronic inflammatory conditions, such as Crohn's disease. In this study, the case of a 33-year-old man with renal dysfunction, nephrotic proteinuria, and erythrocyturia is described. He had had a history of Crohn's disease for 8 years and had been treated with adalimumab for the past 7 years. The diagnosis of IgAN was confirmed by kidney biopsy. After discontinuance of adalimumab and the induction of corticosteroid therapy, he made a remarkable recovery. Four years after the first presentation of IgAN and discontinuation of adalimumab, his renal function was normal with no proteinuria and only mild erythrocyturia.

Abstract
Generalized pustular psoriasis (GPP) is a severe, life-threatening disease that represents a major therapeutic challenge. There is a lack of randomized controlled trials assessing the efficacy of various treatment options for GPP. TNFα inhibitors have proven to be effective and are increasingly used in this indication. In the current paper, we present two patients with GPP treated with infliximab (Ifx) and a literature review appraising currently available data on the use of Ifx in GPP. Case 1 was a 73-year-old woman with GPP who exhibited lack of treatment response or primary intolerance to standard therapeutic options (high-dose acitretin, methotrexate, cyclosporine A, and methylprednisolone). However, Ifx therapy combined with low-dose acitretin resulted in rapid and sustained resolution of skin lesions. Case 2 was a 60-year-old man with GPP and numerous comorbidities who was initially treated with Ifx in combination with methotrexate, with good treatment response for 9 months. Following an infection-induced flare of GPP at week 38, methotrexate was discontinued in favor of low-dose acitretin and Ifx continued. This regimen again resulted in rapid resolution of pustules. We present these cases to highlight the advantage of long-term Ifx therapy with low-dose acitretin in GPP.

IgA nephropathy (IgAN) is commonly associated with psoriasis; however, psoriasis presenting with crescentic IgAN is uncommon. A 49-year-old man with erythrodermic psoriasis with arthritis and stage 2 chronic kidney disease presented to the emergency department with worsening peripheral oedema and difficulty breathing. The patient had been hospitalised previously for a psoriasis flare. He was found to have an acute kidney injury on chronic kidney disease and was diagnosed with crescentic IgA glomerulonephritis on his first hospitalisation. He was treated with corticosteroids and was discharged stable with a plan to start cyclophosphamide in the outpatient setting. On his current hospitalisation, cyclophosphamide was added to his corticosteroids. Crescentic IgAN is rare. Its management has been based largely on observational studies. Our case highlights the importance of starting combined corticosteroids and cyclophosphamide early in crescentic IgAN and that corticosteroid monotherapy is insufficient in controlling disease progression.

Abstract
C-C chemokine receptor 6 (CCR6) is a susceptibility gene of various immune-related diseases, which was suggested to be shared with immunoglobulin A nephropathy (IgAN). In this study, we aimed to identify the functional variants. First, we analyzed the associations of CCR6 common and rare variants detected by multi-platform chips with IgAN susceptibility using imputation and identified 68 significantly associated common variants located in the regulatory region. Among them, rs3093023 showed both statistical significance (rs3093023-A, odds ratio [OR] = 1.15, P = 2.00 × 10−2) and the expression quantitative trait loci (eQTL) effect (P = 1.45 × 10−3). It was independently replicated (rs3093023-A, OR = 1.18, P = 5.56 × 10−3) and the association was reinforced in the meta-analysis (rs3093023-A, OR = 1.17, P = 6.14 × 10−7). Although rs3093023 was in a strong linkage disequilibrium with the reported CCR6 functional variant dinucleotide polymorphism, CCR6DNP, the alleles of rs3093023 (G>A) rather than of CCR6DNP were shown differential nuclear protein binding effect by electrophoretic mobility shift assay. The RegulomeDB and JASPAR databases predicted Pou2f1 as the potential transcription factor, which was negatively associated with CCR6 mRNA (r = −0.60, P = 3.94 × 10−9). At the mRNA level, the eQTL effect of CCR6 was validated (P = 4.39 × 10−2), and CCR6 was positively associated with the expression of CCR4 and IL-17A rather than that of CXCR3 and IFNG. At the protein level, a higher CCR6+ cell ratio was observed in a risk allele dose-dependent manner in lymphocytes (P = 3.57 × 10−2), CD3+ T cells (P = 4.54 × 10−2), and CD4+ T cells (P = 1.32 × 10−2), but not in CD8+ T cells. Clinical-pathological analysis showed that rs3093023 risk allele was significantly associated with diastolic blood pressure, serum creatinine, and high ratio of tubular atrophy/interstitial fibrosis. Overall, the rs3093023 was prioritized as the function variant in CCR6, which may contribute to IgAN susceptibility by regulating Th17 cells.
