Meta-Analysis Review
A PRISMA-compliant systematic review and network meta-analysis on the efficacy between different regimens based on Tripterygium wilfordii Hook F in patients with primary nephrotic syndrome.
BACKGROUND
The present study aims to comprehensively determine the efficacy of different therapy regimens based on Tripterygium wilfordii Hook F (TwHF) for patients with primary nephrotic syndrome (PNS) using network meta-analysis method.
METHODS
Seven electronic databases were searched to identify randomized controlled trials (RCTs) that compared the differences between different therapy regimens based on TwHF for patients with PNS. The risk of bias in included RCTs was evaluated according to the Cochrane Handbook version 5.2.0. Network meta-analysis was performed to compare different regimens. Primary outcomes were complete remission rate and total remission rate. The secondary outcomes were hr urinary protein excretion, serum albumin, serum creatinine, and urea nitrogen. Data analysis was performed using R software.
RESULTS
A total of 40 studies involving 2846 patients with PNS were included. Compared with prednisone, the improvement in total remission rate and complete remission rate was associated with TwHF alone (odds ratio [OR] = 4.80, 95% credible intervals [CrI]: 2.20-10.00; OR = 6.30, 95% CrI: 2.90-13.00, respectively), TwHF+prednisone (OR = 2.10, 95% CrI: 1.30-3.50; OR = 2.40, 95% CrI: 1.50-3.80, respectively), TwHF+CPA (OR = 12.00, 95% CrI: 1.10-150.00; OR = 16.00, 95% CrI: 1.60-170.00, respectively), and TwHF+Cyclosporine A (OR = 28.00, 95% CrI: 3.20-250.00; OR = 35.00, 95% CrI: 4.50-270.00, respectively). Compared with TwHF alone, TwHF+prednisone showed less benefit in improving total remission rate and complete remission rate (OR = 0.44, 95% CrI: 0.21-0.91; OR = 0.38, 95% CrI: 0.19-0.77, respectively). TwHF alone, TwHF+prednisone could significantly reduce hr urinary protein excretion (MD = -0.69, 95% CrI: -1.30 to -0.14; MD = -1.00, 95% CrI: -1.90 to -0.14, respectively) and increase serum albumin (MD = 5.90, 95% CrI: 2.50-9.30; MD = 3.40, 95% CrI: 1.30-5.50, respectively) when compared to prednisone alone. TwHF alone showed significant reduction in serum creatinine when compared to CPA (MD = -19.00, 95% CrI: -37.00 to -0.56).
CONCLUSIONS
TwHF alone, the addition TwHF to prednisone showed more benefit in improving total and complete remission rate, hr urinary protein excretion, serum albumin, and serum creatinine.

Meta-Analysis Review
BACKGROUND
In nephrotic syndrome protein leaks from blood into the urine through the glomeruli resulting in hypoproteinaemia and generalised oedema. While most children with nephrotic syndrome respond to corticosteroids, 80% experience a relapsing course. Corticosteroids have reduced the death rate to around 3%. However, corticosteroids have well recognised potentially serious adverse effects such as obesity, poor growth, hypertension, diabetes mellitus, osteoporosis, and behavioural disturbances. This is an update of a review first published in 2000 and updated in 2002, 2005, 2007, and 2015.
OBJECTIVES
The aim of this review was to assess the benefits and harms of different corticosteroid regimens in children with steroid-sensitive nephrotic syndrome (SSNS). The benefits and harms of therapy were studied in two groups of children 1) children in their initial episode of SSNS, and 2) children who experience a relapsing course of SSNS.
SEARCH METHODS
We searched the Cochrane Kidney and Transplant Register of Studies up to 30 May 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) performed in children (one to 18 years) in their initial or subsequent episode of SSNS, comparing different durations, total doses or other dose strategies using any corticosteroid agent.
DATA COLLECTION AND ANALYSIS
Two authors independently assessed risk of bias and extracted data. Results were expressed as risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI).
MAIN RESULTS
In this 2020 review update 16 new included studies were identified providing a total of 48 included studies with 3941 randomised participants. Risk of bias methodology was often poorly performed with only 25 studies and 22 studies respectively assessed to be at low risk for random sequence generation and allocation concealment. Only nine studies (19%) were at low risk of bias for performance (blinding of participants and personnel) and 11 studies were at low risk of detection bias (blinding of outcome assessment); nine of these studies were placebo-controlled RCTs. Twenty-two studies (fewer than 50%) were at low risk for attrition bias and 23 studies were at low risk for reporting bias (selective outcome reporting). In seven studies, which evaluated children in their initial episode of SSNS and were at low risk of bias for selection bias, there is little or no difference in the number of children with frequent relapses when comparing two months of prednisone with three months or more (RR 0.99, 95% CI 0.82 to 1.19; 585 participants, 4 studies; I2 = 0%) or when comparing three months with five to seven months of therapy (RR 0.99, 95% CI 0.74 to 1.33; 376 participants, 3 studies; I2 = 35%; high certainty evidence). In analyses of eight studies at low risk of selection bias, there is little or no difference in the number of children with any relapse by 12 to 24 months when comparing two months of prednisone with three months or more (RR 0.91, 95% CI 0.78 to 1.06; 637 participants; 5 studies; I2 = 47%) or when comparing three months with five to seven months of therapy (RR 0.88, 95% CI 0.70 to 1.11; 377 participants, 3 studies; I2 = 53%). Little or no difference was noted in adverse effects between the different treatment durations. Among children with relapsing SSNS, two small studies showed that time to remission did not differ between prednisone doses of 1 mg/kg compared with the conventional dose of 2 mg/kg (MD 0.71 days, 95% CI -0.43 to 1.86; 79 participants) and that the total prednisone dose administered was lower (MD -20.60 mg/kg, 95% CI -25.65 to -15.55; 20 participants). Two studies found little or no difference in the number with relapse at six months when comparing dosing by weight with dosing by surface area (RR 1.03, 95% CI 0.71 to 1.49; 146 participants). One study found a reduced risk of relapse with low daily dosing compared with alternate daily dosing (MD -0.90 number of relapses/year, 95% CI -1.33 to -0.47). Four studies found that in children with frequently relapsing disease, daily prednisone during viral infections compared with alternate-day prednisone or no treatment reduced the risk of relapse.
AUTHORS' CONCLUSIONS
There are now four well designed studies randomising 823 children which have clearly demonstrated that there is no benefit of prolonging prednisone therapy beyond two to three months in the first episode of SSNS. Small studies in children with relapsing disease have identified no differences in the times to remission using half the conventional induction dose of 2 mg/kg or 60 mg/m2. It is imperative that a much larger study be carried out to confirm these findings. Lower dose prednisone therapy administered daily during an upper respiratory infection or other infection reduces the risk of relapse compared with continuing alternate-day prednisone or no prednisone based on four small studies. The results of a much larger RCT enrolling more than 300 children are awaited to determine the relative efficacies and adverse effects of using alternate-day compared with daily prednisone to prevent relapse in children with intercurrent infections.

Meta-Analysis Review
BACKGROUND AND AIMS
Ten percent to 20% of children with autoimmune hepatitis (AIH) require second-line therapy to achieve remission. Although current guidelines exist on first-line management, evidence for second-line therapy in treatment-refractory patients is lacking. Our aim was to perform a systematic review and meta-analysis of the efficacy and safety of second-line treatments used in this population.
METHODS
Electronic and manual searches were used to identify potential studies for inclusion. Studies were selected based on reported response rates to second-line therapies in children who failed response to prednisone and azathioprine. Data extraction and risk of bias assessment were performed independently by 2 reviewers. Meta-analysis using weighted estimate of response rates at 6 months was performed for each treatment option. Heterogeneity was assessed.
RESULTS
Fifteen studies of 76 pediatric patients with AIH were included in the review. Overall response rates at 6 months were estimated as 36% for mycophenolate mofetil (MMF) (N = 34, 95% confidence interval [CI] (16-57)), and 50% for tacrolimus (N = 4, 95% CI (0-100%)) and 83% for cyclosporine (N = 15, 95% CI (66%-100%)). Adverse effects were most frequent with cyclosporine (64% experiencing at least 1 adverse effect) followed by tacrolimus (54%) and MMF (48%). Pooled estimates of adverse events were 78% for cyclosporine (95% CI (54%-100%)), 42% for tacrolimus (95% CI (0%-85%)) and 45% for MMF (95% CI (25%-68%)). Sensitivity analyses were not performed due to small sample size.
CONCLUSIONS
Cyclosporine had the highest response rate at 6 months in children with standard-treatment-refractory AIH; however, it also had the highest rate of adverse events. MMF was the second most efficacious option with a low adverse effect rate.

Review
BACKGROUND
Immunoglobulin G4-related disease (IgG4-RD) is a systemic fibro-inflammatory condition with an unclear pathophysiological mechanism affecting different parts of the body. If untreated, the disease can lead to fibrosis and irreversible organ damage. IgG4-RD mostly has been described in adults, hence it is generally unknown among pediatricians. This systematic search of the literature provides an overview of all reports published on IgG4-RD in children in order to create awareness of IgG4-RD in pediatrics and to emphasize the broad clinical presentation of this disease.
METHODS
A systematic literature search of Embase, Medline, Web-of-Science, PubMed publisher, Cochrane and Google Scholar was performed for case reports on IgG4-RD in children.
RESULTS
Of total 740 articles identified by the search, 22 case reports including 25 cases of IgG4-RD in children were found. The median age of the children was 13 years, of which 64 % were girls. IgG4-related orbital disease (44 %) and autoimmune pancreatitis type 1/IgG4-related pancreatitis (12 %) predominantly occurred. Less frequently, other manifestations as pulmonary manifestation, cholangitis and lymphadenopathy were also found. Almost all cases were histologically proven. Prednisone was the first choice of treatment leading to favorable clinical response in 83 % of the cases. Maintenance therapy with steroid sparing agents was required in 43 % of the cases needing therapy. Rituximab was successful in all 4 cases, whereas, the disease modifying rheumatic drugs (DMARDs) mycophenolate mofetil, azathioprine and methotrexate were effective in almost 50 % of the cases.
CONCLUSION
IgG4-RD in children is a generally unknown disease among pediatricians, but several pediatric cases have been described. Prednisone is the first choice of treatment leading to disease remission in the majority of the cases. DMARDs and rituximab are alternative effective steroid sparing agents with more positive evidence for the latter.

Review
BACKGROUND
Inclusion body myositis (IBM) is a late-onset inflammatory muscle disease (myopathy) associated with progressive proximal and distal limb muscle atrophy and weakness. Treatment options have attempted to target inflammatory and atrophic features of this condition (for example with immunosuppressive and immunomodulating drugs, anabolic steroids, and antioxidant treatments), although as yet there is no known effective treatment for reversing or minimising the progression of inclusion body myositis. In this review we have considered the benefits, adverse effects, and costs of treatment in targeting cardinal effects of the condition, namely muscle atrophy, weakness, and functional impairment.
OBJECTIVES
To assess the effects of treatment for IBM.
SEARCH METHODS
On 7 October 2014 we searched the Cochrane Neuromuscular Disease Group Specialized Register, the Cochrane Central Register for Controlled Trials (CENTRAL), MEDLINE, and EMBASE. Additionally in November 2014 we searched clinical trials registries for ongoing or completed but unpublished trials.
SELECTION CRITERIA
We considered randomised or quasi-randomised trials, including cross-over trials, of treatment for IBM in adults compared to placebo or any other treatment for inclusion in the review. We specifically excluded people with familial IBM and hereditary inclusion body myopathy, but we included people who had connective tissue and autoimmune diseases associated with IBM, which may or may not be identified in trials. We did not include studies of exercise therapy or dysphagia management, which are topics of other Cochrane systematic reviews.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodological procedures.
MAIN RESULTS
The review included 10 trials (249 participants) using different treatment regimens. Seven of the 10 trials assessed single agents, and 3 assessed combined agents. Many of the studies did not present adequate data for the reporting of the primary outcome of the review, which was the percentage change in muscle strength score at six months. Pooled data from two trials of interferon beta-1a (n = 58) identified no important difference in normalised manual muscle strength sum scores from baseline to six months (mean difference (MD) -0.06, 95% CI -0.15 to 0.03) between IFN beta-1a and placebo (moderate-quality evidence). A single trial of methotrexate (MTX) (n = 44) provided moderate-quality evidence that MTX did not arrest or slow disease progression, based on reported percentage change in manual muscle strength sum scores at 12 months. None of the fully published trials were adequately powered to detect a treatment effect. We assessed six of the nine fully published trials as providing very low-quality evidence in relation to the primary outcome measure. Three trials (n = 78) compared intravenous immunoglobulin (combined in one trial with prednisone) to a placebo, but we were unable to perform meta-analysis because of variations in study analysis and presentation of trial data, with no access to the primary data for re-analysis. Other comparisons were also reported in single trials. An open trial of anti-T lymphocyte immunoglobulin (ATG) combined with MTX versus MTX provided very low-quality evidence in favour of the combined therapy, based on percentage change in quantitative muscle strength sum scores at 12 months (MD 12.50%, 95% CI 2.43 to 22.57). Data from trials of oxandrolone versus placebo, azathioprine (AZA) combined with MTX versus MTX, and arimoclomol versus placebo did not allow us to report either normalised or percentage change in muscle strength sum scores. A complete analysis of the effects of arimoclomol is pending data publication. Studies of simvastatin and bimagrumab (BYM338) are ongoing. All analysed trials reported adverse events. Only 1 of the 10 trials interpreted these for statistical significance. None of the trials included prespecified criteria for significant adverse events.
AUTHORS' CONCLUSIONS
Trials of interferon beta-1a and MTX provided moderate-quality evidence of having no effect on the progression of IBM. Overall trial design limitations including risk of bias, low numbers of participants, and short duration make it difficult to say whether or not any of the drug treatments included in this review were effective. An open trial of ATG combined with MTX versus MTX provided very low-quality evidence in favour of the combined therapy based on the percentage change data given. We were unable to draw conclusions from trials of IVIg, oxandrolone, and AZA plus MTX versus MTX. We need more randomised controlled trials that are larger, of longer duration, and that use fully validated, standardised, and responsive outcome measures.

Meta-Analysis Review
BACKGROUND
Glucocorticoid (GC) therapy has been shown to prevent Graves' ophthalmopathy (GO) progression following radioactive iodine (RAI) treatment. However, the optimal regimen is controversial, with studies from recent years suggesting the use of lower doses and shorter GC treatment courses.
METHODS
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and retrospective controlled trials comparing GC regimens versus placebo, no treatment, or other GC regimens.
RESULTS
Eight trials evaluating 850 patients fulfilled inclusion criteria. In patients with preexisting GO, standard dose prednisone (0.4-0.5 mg/kg tapered over 3 months) was very effective for prevention of GO progression (OR 0.14 [CI 0.06-0.35], p<0.01) in patients with mild to moderate GO. Two studies evaluated low-dose prednisone (0.2-0.3 mg/kg for 4-6 weeks) in patients with mild GO or risk factors, but were limited by not including patients with preexisting GO in the control groups. Therefore, the two low-dose groups were evaluated using indirect comparisons with control groups matched for age and clinical activity score, showing excellent efficacy versus no treatment or placebo (OR 0.20 [CI 0.07-0.60], p=0.004) and no significant difference compared with standard dose (OR 1.7 [CI 0.52-5.52], p=0.47). In patients without preexisting GO, steroid prophylaxis had no beneficial effect (OR 1.87 [CI 0.81-4.3]), though there were insufficient data regarding patients with risk factors for GO development. GC prophylaxis had no impact on hyperthyroidism resolution (OR 1.05 [CI 0.69-1.58]), and GC side effects were common but mild.
CONCLUSIONS
Current evidence supports a three-tier approach for prevention of GO progression following RAI. Standard dose prednisone is the best validated regimen and should be used in patients with mild to moderate GO who have high risk of progression, while low dose prednisone can be used in patients with mild GO, and in patients without preexisting GO who have risk factors and are selected for GC prophylaxis. Patients without preexisting GO and without risk factors should not be treated with GC prophylaxis.

Review
INTRODUCTION
Rheumatoid arthritis is frequently associated with hypertension, which has been shown to increase the risk of cardiovascular disease in these patients. The aim of this systematic review was to explore demographic, behavioural or clinical factors including medication use, associated with incident hypertension in rheumatoid arthritis.
METHODS
MEDLINE and Scopus were searched for eligible studies that longitudinally investigated incident hypertension or changes in blood pressure (BP) in rheumatoid arthritis patients. Publications were screened by two reviewers according to predetermined inclusion and exclusion criteria. The quality of included studies was assessed via the Newcastle Ottawa Scale and Cochrane Risk of Bias Tool.
RESULTS
Fourteen studies were deemed eligible and included in this review. The proportion of female subjects ranged from 12 to 87% and the mean age ranged from 47 to 61 years. Regular exercise was associated with a decrease in systolic BP, p = 0.021. Methotrexate was associated with decreased risk of hypertension in two studies. LEF was associated with increased BP in two studies. COX-2 inhibitors were associated with systolic BP and diastolic BP variability (p = 0.009, 0.039, respectively) in one study. Prednisone was found to increase BP and risk of hypertension in three studies. The risk of hypertension in patients taking biologic disease modifying anti-rheumatic drugs (DMARDs) is unclear as some studies report increased BP while others report no difference for biologic compared to conventional DMARDs.
CONCLUSION
Despite limited longitudinal studies exploring this topic, methotrexate and exercise were shown to protect against risk of hypertension in RA patients, while prednisone and COX-2 inhibitors may increase risk of hypertension.

Review
BACKGROUND
IgA vasculitis (IgAV), previously known as Henoch-Schönlein purpura, is the most common vasculitis of childhood but may also occur in adults. This small vessel vasculitis is characterised by palpable purpura, abdominal pain, arthritis or arthralgia and kidney involvement. This is an update of a review first published in 2009 and updated in 2015.
OBJECTIVES
To evaluate the benefits and harms of different agents (used singularly or in combination) compared with placebo, no treatment or any other agent for (1) the prevention of severe kidney disease in people with IgAV with or without kidney involvement at onset, (2) the treatment of established severe kidney disease (macroscopic haematuria, proteinuria, nephritic syndrome, nephrotic syndrome with or without acute kidney failure) in IgAV, and (3) the prevention of recurrent episodes of IgAV-associated kidney disease.
SEARCH METHODS
We searched the Cochrane Kidney and Transplant Register of Studies up to 2 February 2023 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) comparing interventions used to prevent or treat kidney disease in IgAV compared with placebo, no treatment or other agents were included.
DATA COLLECTION AND ANALYSIS
Two authors independently determined study eligibility, assessed the risk of bias and extracted data from each study. Statistical analyses were performed using the random-effects model, and the results were expressed as risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes with 95% confidence intervals (CI). Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
MAIN RESULTS
Twenty studies (1963 enrolled participants) were identified; one three-arm study has been assessed as two studies. Nine studies were at low risk of bias for sequence generation (selection bias), and nine studies were at low risk of bias for allocation concealment (selection bias). Blinding of participants and personnel (performance bias) and outcome assessment (detection bias) was at low risk of bias in four and seven studies, respectively. Nine studies reported complete outcome data (attrition bias), while 10 studies reported expected outcomes, so were at low risk of reporting bias. Five studies were at low risk of other bias. Eleven studies evaluated therapy to prevent persistent kidney disease in IgAV with or without kidney involvement at presentation. There was probably no difference in the risk of persistent kidney disease any time after treatment (5 studies, 746 children: RR 0.74, 95% CI 0.42 to 1.32) or at one, three, six and 12 months in children given prednisone for 14 to 28 days at presentation of IgAV compared with placebo or supportive treatment (moderate certainty evidence). There may be no differences in the risk of any persistent kidney disease with antiplatelet therapy (three studies) or heparin (two studies) in children with or without any kidney disease at study entry, although heparin may reduce the risk of proteinuria by three months compared with placebo or no specific treatment (2 studies, 317 children: RR 0.47, 95% CI 0.31 to 0.73). One study comparing montelukast with placebo found no differences in outcomes as assessed by severity scale scores. Nine studies examined the treatment of severe IgAV-associated kidney disease. In two studies (one involving 56 children and the other involving 54 adults), there may be no differences in efficacy outcomes or adverse effects with cyclophosphamide compared with placebo or supportive treatment. In two studies, there may be no differences in the numbers achieving remission of proteinuria with intravenous (IV) cyclophosphamide compared with mycophenolate mofetil (MMF) (65 children evaluated) or tacrolimus (142 children evaluated). In three small studies comparing cyclosporin with methylprednisolone (15 children), MMF with azathioprine (26 children), or MMF with leflunomide (19 children), it is unclear whether the treatment had any effect on the numbers in remission or the degree of proteinuria between treatment groups because of small numbers of included participants. In one study comparing plasmapheresis, cyclophosphamide and methylprednisolone with cyclophosphamide and methylprednisolone, there may be no difference in the numbers achieving remission. One study compared fosinopril with no specific therapy and reported fosinopril reduced the number of participants with proteinuria. No studies were identified that evaluated the efficacy of therapy on kidney disease in participants with recurrent episodes of IgAV.
AUTHORS' CONCLUSIONS
There are no substantial changes in conclusions from this update compared with the initial review or the previous update despite the addition of five studies. From generally low to moderate certainty evidence, we found that there may be little or no benefit in the use of corticosteroids or antiplatelet agents to prevent persistent kidney disease in children with IgAV in participants with no or minimal kidney involvement at presentation. We did not find any studies which evaluated corticosteroids in children presenting with IgAV and nephritic and/or nephrotic syndrome, although corticosteroids are recommended in such children in guidelines. Though heparin may be effective in reducing proteinuria, this potentially dangerous therapy is not justified to prevent serious kidney disease when few children with IgAV develop severe kidney disease. There may be no benefit of cyclophosphamide compared with no specific treatment or corticosteroids. While there may be no benefit in the efficacy of MMF or tacrolimus compared with IV cyclophosphamide in children or adults with IgAV and severe kidney disease, adverse effects, particularly infections, may be lower in MMF or tacrolimus-treated children. Because of small patient numbers and events leading to imprecision in results, it remains unclear whether cyclosporin, MMF or leflunomide have any role in the treatment of children with IgAV and severe kidney disease. We did not identify any studies which evaluated corticosteroids.

Meta-Analysis Review
A promising strategy for controlling repeated implantation failure (RIF) may be the use of hydroxychloroquine (HCQ). To the best of our knowledge, no systematic review has been conducted on the effects of hydroxychloroquine on pregnancy outcomes. A systematic research of the following electronic databases was conducted: Cochrane, EMBASE-Ovid, PubMed, Web of Science, and Scopus from inception to December 2021, using the following keywords [hydroxychloroquine] AND [infertility]. Fertilization and rate of live birth were significantly higher in the HCQ+ prednisone (PDN) group than in the PDN alone group. However, the abortion rate was not different between the two groups. The meta-analysis of two studies revealed no statistical significance between the PDN group and HCQ+PDN group regarding clinical pregnancy rate (OR=.14 [95%CI: 0.4-4.370]; heterogeneity; P=0.13; I2=54%; random effect model) and implantation rate (OR=1.99 [95%CI: 0.94-4.2]; heterogeneity; P=0.37; I2=0%; fixed-effect model). While HCQ may help improve fertilization and live birth rates, adding it to prednisone did not improve overall pregnancy outcomes. This systematic review should be used with caution due to the small size, study design, and difference in the studies' population.
