Comparative Study Meta-Analysis
BACKGROUND
Steroid-sparing adjuvants may enhance oral glucocorticoid benefits in pemphigus treatment. Selecting the optimal therapeutic option among various first-line steroid-sparing adjuvants is often a clinical challenge due to the lack of head-to-head clinical trials.
OBJECTIVE
To determine the best first-line steroid-sparing adjuvants for pemphigus treatment.
METHODS
Randomized controlled trials comparing different steroid-sparing adjuvants in patients with pemphigus were identified through a systematic literature search and subjected to a network meta-analysis. The primary outcomes were the proportion of remission and the mean cumulative glucocorticoid dose.
RESULTS
Ten trials involving 592 patients were analyzed. Among the 7 steroid-sparing adjuvants evaluated, rituximab was the most effective for achieving remission and was more effective than steroid alone (odds ratio, 14.35; 95% confidence interval [CI], 4.71-43.68). Rituximab, azathioprine, and cyclophosphamide pulse therapy enabled the reduction of the cumulative glucocorticoid doses compared to the use of steroid alone: mean differences, -11,830.5 mg (95% CI, -14,089.48 to -9571.52), -3032.48 mg (-4700.74 to -1364.22), and -2469.54 mg (-4128.42 to -810.66), respectively.
LIMITATIONS
The results were driven primarily by a small number of studies, and the effect estimates are imprecise because of indirect comparisons.
CONCLUSION
Network meta-analysis showed that rituximab appears to be an efficacious, well tolerated steroid-sparing adjuvant for pemphigus.

Meta-Analysis
Management of lupus nephritis: a systematic literature review informing the 2019 update of the joint EULAR and European Renal Association-European Dialysis and Transplant Association (EULAR/ERA-EDTA) recommendations.
OBJECTIVES
To analyse the current evidence for the management of lupus nephritis (LN) informing the 2019 update of the EULAR/European Renal Association-European Dialysis and Transplant Association recommendations.
METHODS
According to the EULAR standardised operating procedures, a PubMed systematic literature review was performed, from January 1, 2012 to December 31, 2018. Since this was an update of the 2012 recommendations, the final level of evidence (LoE) and grading of recommendations considered the total body of evidence, including literature prior to 2012.
RESULTS
We identified 387 relevant articles. High-quality randomised evidence supports the use of immunosuppressive treatment for class III and class IV LN (LoE 1a), and moderate-level evidence supports the use of immunosuppressive treatment for pure class V LN with nephrotic-range proteinuria (LoE 2b). Treatment should aim for at least 25% reduction in proteinuria at 3 months, 50% at 6 months and complete renal response (<500-700 mg/day) at 12 months (LoE 2a-2b). High-quality evidence supports the use of mycophenolate mofetil/mycophenolic acid (MMF/MPA) or low-dose intravenous cyclophosphamide (CY) as initial treatment of active class III/IV LN (LoE 1a). Combination of tacrolimus with MMF/MPA and high-dose CY are alternatives in specific circumstances (LoE 1a). There is low-quality level evidence to guide optimal duration of immunosuppression in LN (LoE 3). In end-stage kidney disease, all methods of kidney replacement treatment can be used, with transplantation having the most favourable outcomes (LoE 2b).
CONCLUSIONS
There is high-quality evidence to guide the initial and subsequent phases of class III/IV LN treatment, but low-to-moderate quality evidence to guide treatment of class V LN, monitoring and optimal duration of immunosuppression.

INTRODUCTION
Studies have suggested that in addition to antimicrobials, some non-antibiotics may alter the gut microbiome. This systematic review sought to determine if there is an association between immunosuppressive agents used in recipients of solid organ transplants (SOT) and alterations in the gut microbiome.
METHODS
English language PubMed and Scopus searches were conducted to identify relevant articles. Inclusion criteria were defined as pertaining to solid organ transplantation, immunosuppression, and the gut microbiome. Articles were excluded if they contained only genetic microbiota descriptions, narrative reviews of bacteria, or described bacteria as a pathogen for infections. PRISMA reporting was used to guide this literature review.
RESULTS
A preliminary search identified 665 articles, of which 75 articles met the inclusion criteria, and 10 articles remained after application of exclusion criteria. Seventy-one percent of articles discussed calcineurin inhibitors, such as tacrolimus, 38% included mycophenolate mofetil, and 52% included steroids, such as prednisone. Some studies utilized a combination of immunosuppressants or had multiple study arms. Seventy percent of the articles indicated changes in quantities of anaerobic bacteria including Ruminococcaceae, Lachnospiraceae, Firmicutes, Bacteroides, and Clostridiales. Combinations of immunosuppressant agents were associated with an increase in colonization of Escherichia coli and Enterococcus sp.
CONCLUSION
Some immunosuppressants are associated with changes in gut flora, but the impact on clinical outcomes is unknown. Robust clinical trials delineating the direct effect of immunosuppressants on the gut microbiome as well as the impact on clinical outcomes are warranted.

Clinical and Investigative Medicine.... Jun 2020We used the Cochrane systematic review to analyze the effectiveness and safety of rituximab for lupus nephritis.
PURPOSE
We used the Cochrane systematic review to analyze the effectiveness and safety of rituximab for lupus nephritis.
METHODS
Systematic search was performed among Cochrane clinical controlled trials database, MEDLINE, MEDLINE-IN-Process and Other Non-Indexed Citations, EMBASE, EBSCO CINAHL, CNKI, VIP and Wanfang database from the establishment of the database to February 2016. The effectiveness and safety were evaluated in terms of the complete remission rate, total remission rate, urinary protein, Systemic Lupus Erythematosus Disease Activity Index changes and adverse events rate. Data were analyzed by the Review Manager Software version 5.3.
RESULTS
Five RCTs that met the inclusion criteria, including a total of 238 patients, were enrolled in our study. The results showed that the complete remission rate in rituximab group was a significantly higher than that of cyclophosphamide group. The difference between the two groups was statistically significant (OR=2.80, 95%CI(1.08,7.26), P=0.03). But there was no significant difference between the two groups in partial and total remission rate. The complete remission rate, partial remission rate and total remission rate in rituximab treatment group was similar compared with mycophenolate mofetil group and rituximab combined with cyclophosphamide group. The adverse reaction rate was also similar among the groups.
CONCLUSION
The study systematically analyzed the effectiveness and safety of rituximab for lupus nephritis, which suggested that the complete remission rate of rituximab in the treatment of lupus nephritis was a significantly higher than that of cyclophosphamide group, while the effectiveness and safety was of no difference compared with cyclophosphamide and mycophenolate mofetil.

Tumefactive demyelinating lesions are an uncommon manifestation of demyelinating disease that mimic primary central nervous system neoplasms and can pose a diagnostic challenge in patients without a pre-existing diagnosis of multiple sclerosis. Although a biopsy may be required to distinguish TDL from neoplasms or infection, certain ancillary and radiographic findings may preclude the need for invasive diagnostic procedures. We describe the case of a 15-year-old boy with a tumefactive demyelinating lesion involving the conus medullaris. An exhaustive systematic literature search of pediatric cases of TDL yielded an additional 78 cases. This review summarizes the current knowledge and recommendations for the diagnosis and management of this condition, highlighting the clinical, demographic, and radiologic features of 79 reported cases, including our own. Furthermore, it underscores areas of the literature where evidence is still lacking. Further research is needed to optimize clinical detection and medical management of this condition.

OBJECTIVE
Rituximab (RTX) has important usage in rheumatoid arthritis and vasculitis. There remains a need for more, better, and safer treatments for patients with lupus nephritis (LN). RTX has been trialed in such patients without definitive conclusions about its effectiveness. As a role for RTX has not been clearly established for LN, we carried out a systematic review and analysis.
METHODS
We identified 31 studies of RTX for class I-VI LN, and assessed complete renal response (CRR) and partial renal response (PRR) using criteria including serum creatinine, proteinuria, and urinary sediment. Due to differences in the pediatric presentation of the disease, studies focusing on pediatric patients were excluded.
RESULTS
One randomized controlled trial (RCT) showed superiority of RTX+cyclophosphamide (CYC) versus CYC alone (64% vs. 21% CRR and 19% vs. 36% PRR). Six prospective and retrospective studies utilizing RTX monotherapy found 66% CRR or PRR in all patients. Eleven studies that investigated RTX in combination with CYC or mycophenolate mofetil (MMF) also found 66% CRR or PRR in all patients. In total, the CRR for Caucasian, East Asian, and Hispanic patients were 77%, 38%, and 28%, respectively.
CONCLUSIONS
RTX appeared to benefit certain LN patients, but most studies were not randomized or properly controlled, were heterogeneous in design, subjects, and LN types, and were not comparable, and must therefore be interpreted cautiously. RTX alone may not deplete B cells sufficiently for the perturbations of LN. In addition, RTX may induce responses differently among patients of different ethnic and racial backgrounds. Furthermore, there were wide variations in the baseline characteristics of the patients, namely LN class, time course of disease, age, and prior immunosuppressive use. We suggest a prospective RCT in patients aged 18-65 years with class IV LN. Ideally, the patients would not have received prior immunosuppression and would better represent different ethnicities. The treatment groups would be RTX, RTX+belimumab, CYC, and MMF groups, with pulse-dose steroids during induction followed by maintenance steroids and MMF. The CRR and PRR would be assessed at 12 and 24 months. This or a similar study might clarify RTX's role in the treatment of LN.

BACKGROUND
Conception, pregnancy, and lactation following solid organ transplantation require appropriate management. The most frequently used immunosuppressive drug combination after solid organ transplantation consists of tacrolimus (Tac) plus mycophenolic acid (MPA). Here, the effects of Tac and MPA on fertility, pregnancy, and lactation are systematically reviewed, and their implications for therapeutic drug monitoring (TDM) are discussed.
METHODS
A systematic literature search was performed (August 19, 2019) using Ovid MEDLINE, EMBASE, the Cochrane Central Register of controlled trials, Google Scholar, and Web of Science, and 102 studies were included. Another 60 were included from the reference list of the published articles.
RESULTS
As MPA is teratogenic, women who are trying to conceive are strongly recommended to switch from MPA to azathioprine. MPA treatment in men during conception seems to have no adverse effect on pregnancy outcomes. Nevertheless, in 2015, the drug label was updated with additional risk minimization measures in a pregnancy prevention program. Data on MPA pharmacokinetics during pregnancy and lactation are limited. Tac treatment during conception, pregnancy, and lactation seems to be safe in terms of the health of the mother, (unborn) child, and allograft. However, Tac may increase the risk of hypertension, preeclampsia, preterm birth, and low birth weight. Infants will ingest very small amounts of Tac via breast milk from mothers treated with Tac. However, no adverse outcomes have been reported in children exposed to Tac during lactation. During pregnancy, changes in Tac pharmacokinetics result in increased unbound to whole-blood Tac concentration ratio. To maintain Tac concentrations within the target range, increased Tac dose and intensified TDM may be required. However, it is unclear if dose adjustments during pregnancy are necessary, considering the higher concentration of (active) unbound Tac.
CONCLUSIONS
Tac treatment during conception, pregnancy and lactation seems to be relatively safe. Due to pharmacokinetic changes during pregnancy, a higher Tac dose might be indicated to maintain target concentrations. However, more evidence is needed to make recommendations on both Tac dose adjustments and alternative matrices than whole-blood for TDM of Tac during pregnancy. MPA treatment in men during conception seems to have no adverse effect on pregnancy outcomes, whereas MPA use in women during conception and pregnancy is strongly discouraged.

Comparative Study Meta-Analysis
OBJECTIVES
A few studies on antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) treatments have shown the therapeutic efficacy of mycophenolate mofetil (MMF). However, the therapeutic efficacy of MMF compared with that of cyclophosphamide (CYC) in patients with AAV has not been established. We conducted a systematic review and meta-analysis to assess the efficacy of MMF as a remission induction therapy in patients with AAV comparing it with the efficacy of CYC.
METHODS
We searched randomised controlled trials (RCTs) comparing the efficacy of MMF with that of CYC in patients with AAV on three different websites: PubMed, Cochrane Library and Google Scholar. We compared the difference in the relative risk (RR) of each outcome based on a Mantel-Haenszel random-effects model.
RESULTS
We analysed data from four RCTs with 300 patients for the study. The 6-month remission rate (RR 1.09, 95% CI 0.86 to 1.38, p=0.48), the 6-month ANCA negativity (RR 1.31, 95% CI 0.91 to 1.90, p=0.15) and the long-term relapse rate (RR 1.36, 95% CI 0.80 to 2.31, p=0.26) were all similar between the two treatments. The rates of death, infection and leucopenia were also similar between the two groups (RR 1.05, 95% CI 0.40 to 2.74, p=0.93; RR 1.26, 95% CI 0.79 to 2.01, p=0.33; RR 0.45, 95% CI 0.16 to 1.32, p=0.15, respectively).
CONCLUSIONS
We found no difference between the therapeutic efficacy of MMF and that of CYC in patients with AAV. MMF may be an alternative remission induction therapy in patients with non-life-threatening AAV.

Meta-Analysis
BACKGROUND
About 80% of children with steroid-sensitive nephrotic syndrome (SSNS) have relapses. Of these children, half relapse frequently, and are at risk of adverse effects from corticosteroids. While non-corticosteroid immunosuppressive medications prolong periods of remission, they have significant potential adverse effects. Currently, there is no consensus about the most appropriate second-line agent in children who are steroid sensitive, but who continue to relapse. In addition, these medications could be used with corticosteroids in the initial episode of SSNS to prolong the period of remission. This is the fourth update of a review first published in 2001 and updated in 2005, 2008 and 2013.
OBJECTIVES
To evaluate the benefits and harms of non-corticosteroid immunosuppressive medications in SSNS in children with a relapsing course of SSNS and in children with their first episode of nephrotic syndrome.
SEARCH METHODS
We searched the Cochrane Kidney and Transplant Register of Studies up to 10 March 2020 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov.
SELECTION CRITERIA
Randomised controlled trials (RCTs) or quasi-RCTs were included if they involved children with SSNS and compared non-corticosteroid immunosuppressive medications with placebo, corticosteroids (prednisone or prednisolone) or no treatment; compared different non-corticosteroid immunosuppressive medications or different doses, durations or routes of administration of the same non-corticosteroid immunosuppressive medication.
DATA COLLECTION AND ANALYSIS
Two authors independently assessed study eligibility, risk of bias of the included studies and extracted data. Statistical analyses were performed using a random-effects model and results expressed as risk ratio (RR) for dichotomous outcomes or mean difference (MD) for continuous outcomes with 95% confidence intervals (CI). The certainty of the evidence was assessed using GRADE.
MAIN RESULTS
We identified 43 studies (91 reports) and included data from 2428 children. Risk of bias assessment indicated that 21 and 24 studies were at low risk of bias for sequence generation and allocation concealment respectively. Nine studies were at low risk of performance bias and 10 were at low risk of detection bias. Thirty-seven and 27 studies were at low risk of incomplete and selective reporting respectively. Rituximab (in combination with calcineurin inhibitors (CNI) and prednisolone) versus CNI and prednisolone probably reduces the number of children who relapse at six months (5 studies, 269 children: RR 0.23, 95% CI 0.12 to 0.43) and 12 months (3 studies, 198 children: RR 0.63, 95% CI 0.42 to 0.93) (moderate certainty evidence). At six months, rituximab resulted in 126 children/1000 relapsing compared with 548 children/1000 treated with conservative treatments. Rituximab may result in infusion reactions (4 studies, 252 children: RR 5.83, 95% CI 1.34 to 25.29). Mycophenolate mofetil (MMF) and levamisole may have similar effects on the number of children who relapse at 12 months (1 study, 149 children: RR 0.90, 95% CI 0.70 to 1.16). MMF may have a similar effect on the number of children relapsing compared to cyclosporin (2 studies, 82 children: RR 1.90, 95% CI 0.66 to 5.46) (low certainty evidence). MMF compared to cyclosporin is probably less likely to result in hypertrichosis (3 studies, 140 children: RR 0.23, 95% CI 0.10 to 0.50) and gum hypertrophy (3 studies, 144 children: RR 0.09, 95% CI 0.07 to 0.42) (low certainty evidence). Levamisole compared with steroids or placebo may reduce the number of children with relapse during treatment (8 studies, 474 children: RR 0.52, 95% CI 0.33 to 0.82) (low certainty evidence). Levamisole compared to cyclophosphamide may make little or no difference to the risk for relapse after 6 to 9 months (2 studies, 97 children: RR 1.17, 95% CI 0.76 to 1.81) (low certainty evidence). Cyclosporin compared with prednisolone may reduce the number of children who relapse (1 study, 104 children: RR 0.33, 95% CI 0.13 to 0.83) (low certainty evidence). Alkylating agents compared with cyclosporin may make little or no difference to the risk of relapse during cyclosporin treatment (2 studies, 95 children: RR 0.91, 95% CI 0.55 to 1.48) (low certainty evidence) but may reduce the risk of relapse at 12 to 24 months (2 studies, 95 children: RR 0.51, 95% CI 0.35 to 0.74), suggesting that the benefit of the alkylating agents may be sustained beyond the on-treatment period (low certainty evidence). Alkylating agents (cyclophosphamide and chlorambucil) compared with prednisone probably reduce the number of children, who experience relapse at six to 12 months (6 studies, 202 children: RR 0.44, 95% CI 0.32 to 0.60) and at 12 to 24 months (4 studies, 59 children: RR 0.20, 95% CI 0.09 to 0.46) (moderate certainty evidence). IV cyclophosphamide may reduce the number of children with relapse compared with oral cyclophosphamide at 6 months (2 studies, 83 children: RR 0.54, 95% CI 0.34 to 0.88), but not at 12 to 24 months (2 studies, 83 children: RR 0.99, 95% CI 0.76 to 1.29) and may result in fewer infections (2 studies, 83 children: RR 0.14, 95% CI 0.03 to 0.72) (low certainty evidence). Cyclophosphamide compared to chlorambucil may make little or no difference in the risk of relapse after 12 months (1 study, 50 children: RR 1.31, 95% CI 0.80 to 2.13) (low certainty evidence).
AUTHORS' CONCLUSIONS
New studies incorporated in this review indicate that rituximab is a valuable additional agent for managing children with steroid-dependent nephrotic syndrome. However, the treatment effect is temporary, and many children will require additional courses of rituximab. The long-term adverse effects of this treatment are not known. Comparative studies of CNIs, MMF, levamisole and alkylating agents have demonstrated little or no differences in efficacy but, because of insufficient power; clinically important differences in treatment effects have not been completely excluded.

Meta-Analysis
BACKGROUND
For severe cases of lichen planopilaris (LPP), unresponsive to first line therapy, systemic or potent agents may be required for disease control. There have been several reports of the off-label use of mycophenolate mofetil (MMF) in patients with LPP or have developed adverse effects to initial agents.
METHODS
A systematic review and meta-analysis was performed according to recommended Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies with ≥5 cases reporting the outcomes of MMF in LPP were pooled and a meta-analysis of proportion was performed. Case reports were excluded from analysis.
RESULTS
A total of six studies were identified and included for meta-analysis, comprising 94 LPP patients. The pooled proportion of any good response (partial or complete) was 69.2% (95% confidence interval (CI): 47.8-77). The pooled proportion of complete response was 20% (95% CI: 10.1-36.3). The pooled proportion of partial responses was 49.2% (95% CI: 30.5-63.7). Side effects occurred in 16.9% (95% CI: 17.6-33.2). of cases, which included elevated LFTs, edema, hyperlipidemia, anemia, herpes zoster infection, photosensitivity, and urinary tract infection.
CONCLUSION
The current evidence for MMF remains limited. However, it appears to be a potential treatment option for patients with severe or recalcitrant LPP who have failed hydroxychloroquine and other immunosuppressants.
