High value of early secretory antigenic target-6 and culture filtrate protein-10 in diagnosis of IgA nephropathy with renal tuberculosis: a retrospective study. Am J Med Sci 2022; 364:638-645. [PMID: 35777424 DOI: 10.1016/j.amjms.2022.06.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 06/12/2022] [Accepted: 06/23/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND This retrospective study aimed to evaluate the diagnostic value of early secretory antigenic target-6 (ESAT-6) and culture filtrate protein-10 (CFP-10) in immunoglobulin A nephropathy (IgAN) associated with renal tuberculosis (RT). METHODS Forty patients with IgAN (IgAN group), 32 patients with RT (RT group), and 52 patients with IgAN associated with RT (IgAN + RT group) were retrospectively selected for this study. A tuberculin skin test (TST) was conducted, and Mycobacterium tuberculosis (MTB) antibody levels were measured. Immunohistochemistry and western blotting were used to determine the expression of ESAT-6 and CFP-10 proteins in renal tissues. RESULTS The positive results of TST and levels of serum and urinary MTB antibodies were higher in the RT group than in the IgAN + RT group. The expression levels of ESAT-6 and CFP-10 proteins were the highest in the IgAN + RT group and lowest in the IgAN group. The receiver operating characteristic curves indicated that the area under curve (AUC) value of the ESAT-6 protein for the diagnosis of IgAN associated with RT was 0.907 and the cut-off value of the integral optical density (IOD) was 26.72. Diagnosis based on ESAT-6 protein levels showed 75% sensitivity and 94.2% specificity. The AUC value of the CFP-10 protein for the diagnosis of IgAN associated with RT was 0.8 and the cut-off value of IOD was 25.67. Detection based on CFP-10 protein levels showed 63.9% sensitivity and 84.6% specificity. CONCLUSIONS Our study provides evidence for the potential of ESAT-6 and CFP-10 proteins as candidate markers in the diagnosis of IgAN associated with RT.

Study protocol: high-dose mizoribine with prednisolone therapy in short-term relapsing steroid-sensitive nephrotic syndrome to prevent frequent relapse (JSKDC05 trial). BMC Nephrol 2018; 19:223. [PMID: 30200895 PMCID: PMC6131840 DOI: 10.1186/s12882-018-1033-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Accepted: 09/02/2018] [Indexed: 11/21/2022] Open
Abstract
Background Eighty percent of children with steroid-sensitive nephrotic syndrome (SSNS) relapse within 2 years and 40–50% patients show frequently-relapsing nephrotic syndrome (FRNS). Patients showing a relapse within 6 months after initial remission are at high risk of FRNS. Since frequent prednisolone treatment for FRNS induces severe prednisolone side effects, development of a treatment to prevent patients from shifting to FRNS is desirable. Mizoribine is an immunosuppressive drug with fewer side effects than prednisolone. Recent studies reported the efficacy of high-dose mizoribine in children with FRNS. Methods/design We conduct a multicenter, open, randomized controlled trial to investigate the efficacy and safety of standard prednisolone plus high-dose mizoribine therapy in children with SSNS showing a relapse within 6 months after an initial remission. Patients are allocated to either standard prednisolone alone treatment group, or standard prednisolone plus high-dose mizoribine group. For the former group, mizoribine is administered at a dose of 10 mg/kg/day once daily and continued for 2 years. The primary endpoint is the duration to frequent relapse. Discussion The results provide important data on use of high-dose mizoribine to prevent SSNS patients from shifting to FRNS. Since blood concentrations of mizoribine have not been investigated in detail until now, there is a possibility that mizoribine is underestimated in favor of other immunosuppressive drugs. In future, high-dose mizoribine therapy may lead to prevention of relapse in children at high risk of FRNS, and to decreased total dose of prednisolone. Trial registration UMIN000005103, (Prospectively registered 1st March 2011).

Abstract
Thrombotic thrombocytopenic purpura (TTP) is a rare but life-threatening disease. Although plasma exchange (PE) therapy and corticosteroids are standard remission induction and maintenance therapies, some patients are easily refractory and frequently relapse under treatment with this therapy, and require additional treatment. However, there are limited data about additional treatment interventions. We report a case of 56-year-old man who was hospitalized for fever, general fatigue and hemoglobinuria. Owing to the symptoms and the laboratory findings of hemolysis, he was diagnosed with TTP. He was treated with PE therapy and corticosteroids, and the TTP went into remission. However, his TTP relapsed and remission induction was attempted again. As a remission maintenance treatment, we used combination therapy with the purine-synthesis inhibitor mizoribine (MZR) and corticosteroids. The administration of MZR maintained disease activity with no adverse event for long periods and allowed us to gradually reduce the corticosteroids dose. Hence, we propose that MZR is an effective treatment for TTP maintenance.

Abstract
Background Mizoribine (MZR) is an immunosuppressive drug used in Japan for treating patients with lupus nephritis and nephrotic syndrome and has been also reportedly effective in patients with immunoglobulin A (IgA) nephropathy. However, to date, few randomized control studies of MZR are performed in patients with IgA nephropathy. Therefore, this prospective, open-label, randomized, controlled trial aimed to investigate the efficacy and safety of adding MZR to standard treatment in these patients, and was conducted between April 1, 2009, and March 31, 2016, as a multicenter study. Methods Patients were randomly assigned (1:1) to receiving standard treatment plus MZR (MZR group) or standard treatment (control group). MZR was administered orally at a dose of 150 mg once daily for 12 months. Results Primary outcomes were the percentage reduction in urinary protein excretion from baseline and the rate of patients with hematuria disappearance 36 months after study initiation. Secondary outcomes were the rate of patients with proteinuria disappearance, clinical remission rate, absolute changes in estimated glomerular filtration rate from baseline, and the change in daily dose of prednisolone. Forty-two patients were randomly assigned to MZR (n = 21) and control groups (n = 21). Nine patients in MZR group and 15 patients in the control group completed the study. No significant differences were observed between the two groups with respect to primary and secondary outcomes. Conclusion The addition of MZR to standard treatment has no beneficial effect on reducing urinary protein excretion and hematuria when treating patients with IgA nephropathy.

Comparison of immunosuppressive therapies for IgA nephropathy after tonsillectomy: three-course versus one-course steroid pulse combined with mizoribine. Int Urol Nephrol 2015; 47:1823-30. [PMID: 26433884 PMCID: PMC4628097 DOI: 10.1007/s11255-015-1118-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2015] [Accepted: 09/19/2015] [Indexed: 01/08/2023]
Abstract
Purpose
It has been reported that steroid pulse therapy for IgA nephropathy improves renal prognosis. However, because of the side effects, steroid dose must be restricted to some cases. Treatment effects of steroid on cases already presenting with reduced renal function are unknown. In this study, we performed tonsillectomy in patients with IgA nephropathy and conducted a comparative study about subsequent immunosuppressive therapy.
Methods
Subjects were patients younger than 70 years of age diagnosed with IgA nephropathy by renal biopsy. Treatment protocols were a single-course steroid pulse combined with mizoribine during a period from August 2006 to June 2010 (Group A; n = 34) and a three-course steroid pulse during a period from July 2010 to March 2013 (Group B; n = 32). Primary end points were excretory amounts of proteinuria, disappearance of proteinuria and hematuria, and exacerbation of renal function. Results In both the groups, proteinuria decreased significantly 12 months after treatment, and no significant difference in alleviation effects on proteinuria was found between groups. eGFR increased significantly 12 months after treatment in Group A, whereas it tended to decrease in Group B. As for the preservation effect on eGFR, Group A showed significantly higher preservation of eGFR. Similar results were shown in the patients whose eGFR at the start of the treatment was less than 60 mL/min/1.73 m2. Conclusions Single-course steroid pulse therapy combined with mizoribine was considered to have a protective effect on the renal function in IgA nephropathy, especially accompanying renal dysfunction.

Abstract
A 65-year-old man was admitted to our hospital with edema and renal dysfunction. He had received a diagnosis of psoriatic arthritis at 50 years of age. As a renal biopsy showed IgA nephropathy (IgAN), bilateral tonsillectomy was performed, and one course of steroid pulse therapy with an oral steroid and mizoribine were subsequently administered. The patient's proteinuria gradually reduced in association with an improvement in the renal function. In addition, the rash and arthralgia were ameliorated. In this case, adding treatment for chronic epipharyngitis accelerated the curative effects, and focal infection therapy consisting of immunosuppressive drugs was effective for both IgAN and psoriatic arthritis.

Abstract
OBJECTIVE To determine the safety and efficacy of long-term use of mizoribine by undertaking a 3-year post-marketing surveillance study. METHODS Subjects were all lupus nephritis patients newly treated with mizoribine between 1 October 2003 and 30 September 2005 at contracted study sites. RESULTS Mizoribine was administered to 881 lupus nephritis patients in the safety analysis set consisting of 946 patients recruited from 281 contracted study sites after satisfying the eligibility criteria. There were 301 events of adverse drug reactions that were observed in 196 (20.7%) of the 946 subjects. There were 34 events of serious adverse drug reactions in 31 patients (3.2%). No deterioration in hematological and biochemical test values was observed, but immunological testing showed significant improvements in C3, CH50, and anti-DNA antibody titers. The negative rate of proteinuria also increased over time. The median steroid dosage was 15 mg/day at the commencement of treatment, but was reduced to 10 mg/day at 12 months and 8 mg/day at 36 months. CONCLUSION The findings of the 3-year long-term drug use surveillance study indicated that mizoribine can be used over the long term with relatively few adverse drug reactions, suggesting its suitability for use in maintenance drug therapy.

Abstract
A 41-year-old male patient was admitted to our hospital due to massive proteinuria and hematuria. His 24-hour urinary protein excretion and the number of urinary erythrocytes were 3.91 g/day and 50–99/high-power field, respectively. A renal biopsy showed a severe pathological pattern of immunoglobulin A nephropathy (IgAN) that involved marked endocapillary proliferation and segmental sclerosis (Oxford-MEST score: M0, E1, S1, T0). Because he had nephrotic-level proteinuria with severe pathological findings, which are tonsillectomy and corticosteroid pulse therapy-resistant characteristics, he received mizoribine for a long period as part of the combination therapy using corticosteroid, tonsillectomy, dipyridamole, warfarin and renin-angiotensin-aldosterone system blockers. Twelve months after the beginning of treatment, his urinary findings were normal. In this report, we describe the pathological findings and successful treatment course, and discuss the potential effects of long-term coadministration of mizoribine for adult IgAN treatment.

Abstract
Background Cytomegalovirus (CMV) infection is endemic worldwide. Although CMV reactivation often becomes a serious problem in immunocompromised patients, the prevalence of CMV reactivation caused by methylprednisolone therapy for ARDS after esophagectomy has yet to be determined. Method Among 175 consecutive patients with thoracic squamous cell esophageal cancer who underwent esophagectomy with extensive lymph node dissection at Akita University Hospital between 2007 and 2010, 11 patients (6.3 %) diagnosed with ARDS during the acute phase of esophagectomy were enrolled and treated with steroid pulse therapy, high-dose (15–20 mg/kg/day) administration and tapering in this retrospective study. Results Seven of the 11 patients (63.6 %) were diagnosed with CMV reactivation based on CMV antigenemia assayed 19.1 days after the start of methylprednisolone administration and were treated with ganciclovir for 39.6 days. Six of the 7 patients (85.7 %) diagnosed with CMV reactivation were administered a total methylprednisolone dose of more than 4,000 mg. Though there was no significant difference between patients with and without CMV reactivation, there was a tendency that patients with CMV reactivation showed a lower minimum number of lymphocytes during the acute phase of esophagectomy (p = 0.051, Student’s t test, average 223.3 and 298.0/μl, respectively). Conclusion Though the number of study patients is small, the prevalence of CMV reactivation caused by high-dose methylprednisolone therapy for ARDS after esophagectomy is remarkably high. This result strikes a note of warning concerning the management of these patients and suggests the importance of screenings for CMV reactivation so as to make an accurate diagnosis and initiate treatment in a timely manner.
