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.

INTRODUCTION
Pruritus is a major and burdensome symptom in atopic dermatitis (AD). The number of systemic treatments available for AD has increased recently, enabling improved patient relief.
OBJECTIVE
To evaluate the effect of AD treatments on pruritus.
METHODS
A systematic literature review and a meta-analysis were conducted to evaluate and compare the effects of treatment used in AD on pruritus. PubMed and Embase databases were searched to find articles published between January 1990 and December 2021. Topical and systemic treatments were studied in patients aged ≥10 years.
RESULTS
Among the 448 articles identified, 56 studies were retained in the systematic review. A total of 15 studies evaluated topical treatments: topical corticosteroids (TCS; 2), calcineurin inhibitors (6), PDE4 inhibitors (3), and Jak inhibitors (4). A total of five studies were included in the meta- analysis. All treatments had a positive effect on pruritus, with a mean overall reduction of 3.32/10, 95% IC [2.32-4.33]. The greatest reduction was observed with halometasone (mean: 4.75), followed by tofacitinib 2% (mean: 4.38). A total of 41 studies evaluated systemic therapies: cyclosporine (6), phototherapy (5), azathioprine (2), dupilumab (9), anti-IL 13 (5), nemolizumab (3), Jak inhibitors (9), mepolizumab (1), and apremilast (1). A total of 17 studies were included in 2 meta-analyses according to the concomitant use or not of TCS. In the meta-analysis without TCS, the overall decrease was 3.07/10, 95% IC [2.58-3.56]. The molecules with the highest efficacy on pruritus were upadacitinib 30 mg (mean: 4.90) and nemolizumab (mean: 4.81).
DISCUSSION
The therapeutic arsenal for AD has increased rapidly, and many molecules are under development. The primary endpoint of clinical trials is most often a score that assesses the severity of AD; however, the assessment of pruritus is also essential. The majority of molecules have a positive effect on pruritus, but the improvement varies between them. Efficacy on pruritus is not always correlated with efficacy on AD lesions; therefore, these two criteria are crucial to evaluate. The limitations of this study were the heterogeneity in the assessment of pruritus, the moment of the assessment, and the concomitant application of TCS or not for studies evaluating systemics. In the future, it would be useful to use standardized criteria for assessing pruritus.

Meta-Analysis Review
BACKGROUND
Non-infectious intermediate, posterior, and panuveitis (NIIPPU) represent a heterogenous collection of autoimmune and inflammatory disorders isolated to or concentrated in the posterior structures of the eye. Because NIIPPU is typically a chronic condition, people with NIIPPU frequently require treatment with steroid-sparing immunosuppressive therapy. Methotrexate, mycophenolate, cyclosporine, azathioprine, and tacrolimus are non-biologic, disease-modifying antirheumatic drugs (DMARDs) which have been used to treat people with NIIPPU.
OBJECTIVES
To compare the effectiveness and safety of selected DMARDs (methotrexate, mycophenolate mofetil, tacrolimus, cyclosporine, and azathioprine) in the treatment of NIIPPU in adults.
SEARCH METHODS
We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register), MEDLINE, Embase, the Latin American and Caribbean Health Sciences database, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform, most recently on 16 April 2021.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) comparing selected DMARDs (methotrexate, mycophenolate, tacrolimus, cyclosporine, and azathioprine) with placebo, standard of care (topical steroids, with or without oral steroids), or with each other.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
We included 11 RCTs with a total of 601 participants in this review. DMARDs versus control Two studies compared an experimental DMARD (cyclosporine A or enteric-coated mycophenolate [EC-MPS]) plus oral steroid with steroid monotherapy. We did not pool these results into a meta-analysis because the dose of cyclosporine used was much higher than that used in current clinical practice. The evidence is very uncertain about whether EC-MPS plus low-dose oral steroid results in a higher proportion of participants achieving control of inflammation over steroid monotherapy (risk ratio [RR] 2.81, 95% confidence interval [CI] 1.10 to 7.17; 1 study, 41 participants; very low-certainty evidence). The change in best-corrected visual acuity (BCVA) was reported separately for right and left eyes. The evidence for improvement (lower logarithm of the minimum angle of resolution (logMAR) indicates better vision) between the groups is very uncertain (mean difference [MD] -0.03 and -0.10, 95% CI -0.96 to 0.90 and -0.27 to 0.07 for right and left, respectively; 1 study, 82 eyes; very low-certainty evidence). No data were available for the following outcomes: proportion of participants achieving a 2-line improvement in visual acuity, with confirmed macular edema, or achieving steroid-sparing control. The evidence for the proportion of participants requiring cessation of medication in the DMARD versus control group is very uncertain (RR 2.61, 95% CI 0.11 to 60.51; 1 study, 41 participants; very low-certainty evidence). Methotrexate versus mycophenolate We were able to combine two studies into a meta-analysis comparing methotrexate versus mycophenolate mofetil. Methotrexate probably results in a slight increase in the proportion of participants achieving control of inflammation, including steroid-sparing control, compared to mycophenolate at six months (RR 1.23, 95% CI 1.01 to 1.50; 2 studies, 261 participants; moderate-certainty evidence). Change in BCVA was reported per eye and the treatments likely result in little to no difference in change in vision (MD 0.01 logMAR higher [worse] for methotrexate versus mycophenolate; 2 studies, 490 eyes; moderate-certainty evidence). No data were available for the proportion of participants achieving a 2-line improvement in visual acuity. The evidence is very uncertain regarding the proportion of participants with confirmed macular edema between methotrexate versus mycophenolate (RR 0.49, 95% CI 0.19 to 1.30; 2 studies, 35 eyes; very low-certainty). Methotrexate versus mycophenolate may result in little to no difference in the proportion of participants requiring cessation of medication (RR 0.99, 95% CI 0.43 to 2.27; 2 studies, 296 participants; low-certainty evidence). Steroids with or without azathioprine versus cyclosporine A Four studies compared steroids with or without azathioprine (oral steroids, intravenous [IV] steroids, or azathioprine) to cyclosporine A. We excluded two studies from the meta-analysis because the participants were treated with 8 mg to 15 mg/kg/day of cyclosporine A, a significantly higher dose than is utilized today because of concerns for nephrotoxicity. The remaining two studies were conducted in all Vogt-Koyanagi-Harada disease (VKH) populations and compared cyclosporine A to azathioprine or IV pulse-dose steroids. The evidence is very uncertain for whether the steroids with or without azathioprine or cyclosporine A influenced the proportion of participants achieving control of inflammation (RR 0.84, 95% CI 0.70 to 1.02; 2 studies, 112 participants; very low-certainty evidence), achieving steroid-sparing control (RR 0.64, 95% CI 0.33 to 1.25; 1 study, 21 participants; very low-certainty evidence), or requiring cessation of medication (RR 0.85, 95% 0.21 to 3.45; 2 studies, 91 participants; very low-certainty evidence). The evidence is uncertain for improvement in BCVA (MD 0.04 logMAR lower [better] with the steroids with or without azathioprine versus cyclosporine A; 2 studies, 91 eyes; very low-certainty evidence). There were no data available (with current cyclosporine A dosing) for the proportion of participants achieving a 2-line improvement in visual acuity or with confirmed macular edema. Studies not included in synthesis We were unable to include three studies in any of the comparisons (in addition to the aforementioned studies excluded based on historic doses of cyclosporine A). One was a dose-response study comparing cyclosporine A to cyclosporine G, a formulation which was never licensed and is not clinically available. We excluded another study from meta-analysis because it compared cyclosporine A and tacrolimus, considered to be of the same class (calcineurin inhibitors). We were unable to combine the third study, which examined tacrolimus monotherapy versus tacrolimus plus oral steroid, with any group.
AUTHORS' CONCLUSIONS
There is a paucity of data regarding which DMARD is most effective or safe in NIIPPU. Studies in general were small, heterogenous in terms of their design and outcome measures, and often did not compare different classes of DMARD with each other. Methotrexate is probably slightly more efficacious than mycophenolate in achieving control of inflammation, including steroid-sparing control (moderate-certainty evidence), although there was insufficient evidence to prefer one medication over the other in the VKH subgroup (very low-certainty evidence). Methotrexate may result in little to no difference in safety outcomes compared to mycophenolate.

JAAD International Dec 2022Systemic glucocorticoids are first-line treatment options for autoimmune blistering diseases; however, their long-term use is associated with significant toxicities. (Review)
Review
BACKGROUND
Systemic glucocorticoids are first-line treatment options for autoimmune blistering diseases; however, their long-term use is associated with significant toxicities.
OBJECTIVE
To evaluate the side effects of steroid-sparing agents and compare them with those of steroids.
METHODS
We searched Cochrane Reviews, Embase, MEDLINE, and Scopus between October 1978 and May 2020 using the keywords "bullous pemphigoid," "pemphigus," "autoimmune blistering diseases," and "side effects." A total of 31 randomized controlled trials and retrospective case series were critically appraised.
RESULTS
This review includes a total of 1685 patients with autoimmune blistering diseases, of whom 781 had bullous pemphigoid and 904 had either pemphigus vulgaris or pemphigus foliaceous.
LIMITATIONS
A major limitation is that because adjuvants are generally used in combination with steroids, only 12 of the studies reviewed included a "steroid-only" arm to allow for a direct comparison of side effects. Additionally, there is inadequate literature and lack of standardized grade reporting of specific side effects of each steroid-sparing agent.
CONCLUSION
In the future, researchers should consider implementing the Common Terminology Criteria for Adverse Events, version 5.0, for reporting of all side effects to allow for consistency and standardization. It would be useful to have an index similar to the Glucocorticoid Toxicity Index to quantify these side effects.

Meta-Analysis
BACKGROUND
To assess the efficacy and safety of rituximab (RTX) in the treatment of neuromyelitis optica spectrum diseases (NMOSDs), and give a guideline on clinical medication.
METHODS
The databases of Pubmed, Embase, Cochrane Library, CNKI, and Wan fang were systematically searched by computer, and the search period was from the establishment of the databases until January 2022. To collect the trials of RTX in the treatment of NMOSDs, two researchers completed literature screening, quality assessment, and data extraction independently. Statistical analysis was performed using Review Manager 5.3 and Stata 15.1 software.
RESULTS
There were 37 studies in the meta-analysis, including 5 randomized controlled trials (RCTs) and 32 observational studies. Meta-analysis results revealed that NMOSDs patients treated with RTX significantly reduced the annualized relapse rate (ARR) (weighted mean difference [WMD] = 1.45, 95% confidence interval [CI]: 1.24-1.66, P < .01) and the Expanded disability status scale (EDSS) scores (WMD = 1.34, 95%CI: 1.25-1.44, P < .01). RTX is more effective than azathioprine (AZA) in the treatment of NMOSDs (ARR: WMD = -0.54, 95% CI: -0.75 to -0.33; EDSS: WMD = -0.65, 95% CI: -0.83 to -0.48; P < .0001).There was no difference in ARR and EDSS scores between anti-aquapor in-4-antibody seropositive NMOSD and seronegative NMOSD patients treated with RTX (ARR: WMD = -0.01, 95% CI: -0.25 to 0.24, P = .96 > 0.05; EDSS: WMD = 0, 95% CI: -0.30 to 0.31, P = .99 > 0.05). In this study, 681 patients were recorded safety data of RTX therapy, 23% (156 patients) had adverse events, and 0.7% (5 patients) of NMOSDs discontinued due to severe adverse reactions.
CONCLUSIONS
NMOSDs patients treated with RTX can significantly reduce the relapse frequency and EDSS scores, and also improve neurological dysfunction, besides the efficacy is better than azathioprine. RTX has a high incidence of adverse reactions, which are mild and with certain self limited, it should be cautious in clinical medication.

Meta-Analysis
OBJECTIVE
To investigate the effectiveness and safety of tripterygium glycosides (TG) tablet for the treatment of Lupus nephritis (LN).
METHODS
Several databases were systematically searched including PubMed, Embase, Cochrane, Wiley, China National Knowledge Infrastructure Database, SinoMed and Wanfang Library till June 20, 2020. Revman5.3 was utilized to analyze the data according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement.
RESULTS
In total, 8 randomized controlled trials involving 583 participants were identified. Meta-analyses showed that, compared with glucocorticoids (GC) alone, the combination with TG tablet provided a statistically significant improvement in total remission (TR) ( = 1.27, 95% : 1.08-1.50, = 0.004), complete remission (CR) ( = 1.61, 95% : 1.05-2.47, = 0.03) and C3 levels ( = 0.27, 95% : 0.14-0.39, < 0.000 1), C4 levels ( = 0.12, 95% : 0.07-0.17, < 0.000 01). No significant differences were seen in TR, CR, proteinuria, serum creatinine, C3 and C4 (TR: = 1.00, 95% : 0.87-1.16, = 0.95; CR: = 1.10, 95% : 0.78-1.56, = 0.58; proteinuria levels: = -0.06, 95% : -0.13 to 0.01, = 0.10; serum creatinine levels: = -0.01, 95%: -7.36 to 7.35, = 1.00; C3 levels: = 0.01, 95%: -0.06 to 0.07, = 0.84; C4 levels: = -0.01, 95%: -0.03 to 0.01, = 0.49) between azathioprine (AZA) / leflomit (LEF) + GC and TG tablet + GC. Adverse events (hepatic dysfunction, nausea, vomitting) showed no statistical differences between the TG tablet + GC group and the GC group. There were more new onset of irregular menstruation in the TG tablet + GC group than those in the AZA + GC ( = 3.57, 95% : 1.40-9.11, = 0.008) /LEF+ GC ( = 6.69, 95% : 2.42-18.46, = 0.000 2) group, but leucopenia lower than those in AZA + GC group ( = 0.38, 95% : 0.17-0.85, = 0.02) and alopecia ( = 0.14, 95% : 0.03-0.77, = 0.02) and rash ( = 0.09, 95% : 0.01-0.69, = 0.02) lower than those in LEF + GC group.
CONCLUSIONS
This review indicates that TG tablet maybe effective in LN treatment. Nevertheless, adverse events cannot be ignored. Large sample, multi-center, high-quality clinical studies are needed to verify the exact effects and safety of TG tablet in treatment of LN.

Immunosuppressants have been applied in the remedy of idiopathic membranous nephropathy (IMN) extensively. Nevertheless, the efficacy and safety of immunosuppressants do not have final conclusion. Thus, a pairwise and network meta-analysis (NMA) was carried out to seek the most recommended therapeutic schedule for patients with IMN. Randomized controlled trials (RCTs) including cyclophosphamide (CTX), mycophenolate mofetil (MMF), tacrolimus-combined mycophenolate mofetil (TAC + MMF), cyclosporine (CsA), tacrolimus (TAC), leflunomide (LEF), chlorambucil (CH), azathioprine (AZA), adrenocorticotropic hormone (ACTH), non-immunosuppressive therapies (CON), steroids (STE), mizoribine (MZB), and rituximab (RIT) for patients with IMN were checked. Risk ratios (RRs) and standard mean difference (SMD) were reckoned to assess dichotomous variable quantities and continuous variable quantities, respectively. Total remission (TR) and 24-h urine total protein (24-h UTP) were compared using pairwise and NMA. Then interventions were ranked on the basis of the surface under the cumulative ranking curve (SUCRA). Our study finally included 51 RCTs and 12 different immunosuppressants. Compared with the CON group, most regimens demonstrated better therapeutic effect in TR, with RR of 2.1 (95% CI) (1.5-2.9) for TAC, 1.9 (1.3-2.8) for RIT, 2.5 (1.2-5.2) for TAC + MMF, 1.9 (1.4-2.7) for CH, 1.8 (1.4-2.4) for CTX, 2.2 (1.0-4.7) for ACTH, 1.6 (1.2-2.1) for CsA, 1.6 (1.0-2.5) for LEF, and 1.6 (1.1-2.2) for MMF. In terms of 24-h UTP, TAC (SMD, -2.3 (95% CI -3.5 to -1.1)), CTX (SMD, -1.7 (95% CI -2.8 to -0.59)), RIT (SMD, -1.8 (95% CI -3.5 to -0.11)), CH (SMD, -2.4 (95% CI -4.3 to -0.49)), AZA (SMD, --4.2 (95% CI -7.7 to -0.68)), and CsA (SMD, -1.7 (95% CI -3 to -0.49)) were significantly superior than the CON group. As for adverse effects (AEs), infections, nausea, emesia, myelosuppression, and glucose intolerance were the collective adverse events for most immunosuppressants. This study indicates that TAC + MMF performed the best in terms of TR, and TAC shows the best effectiveness on 24-h UTP compared with other regimens. On the contrary, there seems to be little advantage on STE alone, LEF, AZA, and MZB in treating patients with IMN compared with CON.

Comparative Analysis of Treatment Outcomes in Patients with Neuromyelitis Optica Spectrum Disorder Treated with Rituximab, Azathioprine, and Mycophenolate Mofetil: A Systematic Review and Meta-analysis.
INTRODUCTION
Neuromyelitis optica spectrum disorder (NMOSD) is a neurological condition consisting of relapse-related disability. Treatment options are limited. This systematic review and meta-analysis aimed to evaluate the effectiveness and tolerability of rituximab (RTX) in comparison to azathioprine (AZT) and mycophenolate mofetil (MMF) for the treatment of NMOSD.
METHODS
A systematic search was conducted among electronic databases, including PubMed, Scopus, EBSCO, and Cochrane, for relevant studies. We included randomized, controlled trials and prospective and retrospective studies evaluating the efficacy and safety of RTX compared to AZT and/or MMF in adult and pediatric patients with NMOSD. The Newcastle-Ottawa Scale (NOS) and Cochrane Collaboration tool were used to determine the risk of bias.
RESULTS
Eleven studies involving 1,086 patients were included in our study. Treatment with RTX generally yielded favorable annualized relapse rate (ARR) and Expanded Disability Status Scale (EDSS) results in comparison to AZT and MMF, despite its variable statistical significance. RTX treatment reduced the relapse rate and hazard risk for relapse (HRR). Patients in the RTX group experienced significantly fewer adverse events, among which the most common were allergies, infections, and leukopenia.
CONCLUSION
In this study, RTX appeared to be superior to AZT and MMF in improving disability and reducing relapse in patients with NMOSD. RTX is also associated with fewer adverse events based on pooled analysis. Future randomized clinical trials are needed to establish the efficacy and safety of RTX in patients with NMOSD.

Meta-Analysis
BACKGROUND
Immunotherapy has been shown to reduce relapses in patients with myelin oligodendrocyte glycoprotein antibody-associated disorder (MOG-AD); however, the superiority of specific treatments remains unclear.
AIM
To identify the efficacy and tolerability of different treatments for MOG-AD.
METHODS
Systematic search in Pubmed, Embase, Web of Science, and Cochrane Library databases from inception to March 1, 2021, were performed. Published articles including patients with MOG-AD and reporting the efficacy or tolerability of two or more types of treatment in preventing relapses were included. Reported outcomes including incidence of relapse, annualized relapse rate (ARR), and side effects were extracted. Network meta-analysis with a random-effect model within a Bayesian framework was conducted. Between group comparisons were estimated using Odds ratio (OR) or mean difference (MD) with 95% credible intervals (CrI).
RESULTS
Twelve studies that compared the efficacy of 10 different treatments in preventing MOG-AD relapse, including 735 patients, were analyzed. In terms of incidence of relapse, intravenous immunoglobulins (IVIG), oral corticosteroids (OC), mycophenolate mofetil (MMF), azathioprine (AZA), and rituximab (RTX) were all significantly more effective than no treatment (ORs ranged from 0.075 to 0.34). On the contrary, disease-modifying therapy (DMT) (OR=1.3, 95% CrI: 0.31 to 5.0) and tacrolimus (TAC) (OR=5.9, 95% CrI: 0.19 to 310) would increase the incidence of relapse. Compared with DMT, IVIG significantly reduced the ARR (MD=-0.85, 95% CrI: -1.7 to -0.098). AZA, MMF, OC and RTX showed a trend to decrease ARR, but those results did not reach significant differences. The combined results for relapse rate and adverse events, as well as ARR and adverse events showed that IVIG and OC were the most effective and tolerable therapies.
CONCLUSIONS
Whilst DMT should be avoided, IVIG and OC may be suited as first-line therapies for patients with MOG-AD. RTX, MMF, and AZA present suitable alternatives.

Review
We aimed to summarise effects and use of non-pharmacological and pharmacological treatments for sarcoidosis with musculoskeletal manifestations. We systematically searched the Cochrane Library, Ovid MEDLINE, Embase, CINAHL, AMED, Scopus, clinical.trials.gov, PROSPERO and PEDro for systematic reviews from 2014 to 2022 and for primary studies from date of inception to March 29, 2022, and studies with patients diagnosed with sarcoidosis with musculoskeletal manifestations. Inclusion criteria required that studies reported effects of non-pharmacological and/or pharmacological treatments or number of patients receiving these treatments. Results were reported narratively and in forest plots. Eleven studies were included. No systematic reviews fulfilled our inclusion criteria. None of the included studies had a control group. We found that between 23 and 100% received corticosteroids, 0-100% received NSAIDs, 5-100% received hydroxychloroquine, 12-100% received methotrexate, 0-100% received TNF inhibitors, and 3-4% received azathioprine. Only ten patients in one study had used non-pharmacological treatments, including occupational therapy, chiropractic and acupuncture. There are no controlled studies on treatment effects for patients with sarcoidosis with musculoskeletal manifestations. We found 11 studies reporting use of pharmacological treatments and only one study reporting use of non-pharmacological treatments. Our study identified major research gaps for pharmacological and non-pharmacological treatment in musculoskeletal sarcoidosis and warrant randomised clinical trials for both.
