Review
Current myasthenia gravis guidelines recommend the use of azathioprine as first-line steroid sparing agent. However, due to its high cost, compliance to azathioprine is low in developing countries. To determine the efficacy and safety of the cheaper methotrexate as an alternative immunosuppressant, Medline/Pubmed, Embase and Cochrane databases and references were searched for clinical trials and observational studies using the search terms: "Myasthenia OR Myasthenia Gravis OR anti AchR antibody positive Myasthenia Gravis OR anti-MuSK antibody Myasthenia Gravis OR MG" AND "Methotrexate". Of 78 possible articles, only 4 were selected using the following eligibility criteria: population: generalized MG patients; intervention: methotrexate; and outcome: effectiveness, steroid sparing efficacy and adverse effects. Two clinical trials and one observational study noted improvement in different MG outcomes in patients given methotrexate. While one randomized controlled clinical trial concluded that methotrexate has no steroid sparing benefit, a single blinded clinical trial established that methotrexate was a better steroid sparing agent than azathioprine starting at 10th month of use. Adverse effects were rare with non-specific pain and elevated transaminases as the most common complaints. Based on available evidence, MTX may be a safe and effective alternative to AZA as steroid sparing agent in developing countries.

BACKGROUND
The best choice of first-line treatment for metastatic hormone-sensitive prostate cancer (mHSPC) is unclear. We aimed to compare the effectiveness and safety determined in randomized clinical trials of doublet and triplet treatments for mHSPC.
METHODS
Medline, Embase, Cochrane Central and ClinicalTrials.gov were searched from inception through July 01, 2022. Eligible studies were phase III randomized clinical trials evaluating androgen deprivation treatment (ADT) alone, doublet therapies [ADT combined with docetaxel (DOC), novel hormonal agents (NHAs), or radiotherapy (RT)], or triplet therapies (NHA+DOC+ADT) as first-line treatments for mHSPC. Outcomes of interest included overall survival (OS), progression-free survival (PFS) and grades 3-5 adverse events (AEs). Subgroup analyses were performed based on tumor burden. The effects of competing treatments were assessed by Bayesian network meta-analysis using R software.
RESULTS
Ten trials with 12,298 patients comparing nine treatments were included. Darolutamide (DARO) +DOC+ADT ranked best in terms of OS benefits (OR 0·52 [95% CI 0·39-0·70]), but its advantages were all statistically insignificant compared with other therapy options except for DOC+ADT (OR 0·68 [95% CI 0·53-0·88]) and RT+ADT (OR 0·57 [95% CI 0·40-0·80]). In terms of PFS, enzalutamide(ENZA)+DOC+ADT (OR 0·32 [95% CI 0·24-0·44]) and abiraterone and prednisone (AAP) +DOC+ADT (OR 0·33 [95% CI 0·25-0·45]) ranked best. For patients with high volume disease (HVD), low volume disease (LVD), and visceral metastases, the optimal therapies were AAP+DOC+ADT (OR 0·52 [95% CI 0·33-0·83]), apalutamide+ADT (OR 0·52 [95% CI 0·26-1·05]) and DARO+DOC+ADT (OR 0·42 [95% CI 0·13-1·34]), respectively. For safety, AAP+DOC+ADT (OR 3·56 [95% CI 1·51-8·43]) ranked worst with the highest risk of grade 3-5 AEs.
CONCLUSIONS
Triple therapies may further improve OS and PFS but may be associated with a decrease in safety. Triplet therapies could be suggested for HVD patients, while doublet combinations should still be preferred for LVD patients.

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.

Meta-Analysis Review
Blastic plasmacytoid dendritic cell neoplasm is a rarely occurring hematologic malignancy with a dismal prognosis. We conducted a meta-analysis for a total of 1312 patients from 24 retrospective studies. The complete remission (CR) rate of acute lymphoblastic leukemia-like induction chemotherapy was 82%, and the overall survival (OS) was 15.75 months; the CR rate of acute myeloid leukemia-like chemotherapy was 51%, and the OS was 7.18 months; and the CR rate of cyclophosphamide, doxorubicin, vincristine and prednisone-like chemotherapy was 50%, and the OS was 12.06 months. Acute lymphoblastic leukemia-like induction chemotherapy has the best CR rate and OS.

Review
PURPOSE OF REVIEW
Undifferentiated connective tissue disease (UCTD) is characterized by the presence of clinical symptoms of a systemic autoimmune disease in addition to laboratory evidence of autoimmunity with the patients not fulfilling any of the widely used classification criteria for classic autoimmune diseases. The presence of UCTD as a separate entity versus an early stage of such diseases as systemic lupus erythematosus (SLE) or scleroderma has long been debated. Given the uncertainty regarding this condition, we performed a systematic review on the topic.
RECENT FINDINGS
UCTD can be subcategorized as evolving (eUCTD) or stable UCTD (sUCTD) based on its evolution towards a definable autoimmune syndrome. Analyzing the data from six UCTD cohorts published in the literature, we found that 28% of patients have an evolving course with the majority developing SLE or rheumatoid arthritis within 5-6 years of the UCTD diagnosis. From the remaining patients, 18% do achieve remission. Published treatment regimens were similar to other mild autoimmune diseases with low-dose prednisone, hydroxychloroquine, and NSAID. One-third of patients did need immune suppressive medications. Importantly, the reported outcomes were excellent with survival rates of more than 90% over 10 years. It has to be noted though that as data on patient related outcomes are not available to date, the exact impact of this condition on quality of life is unclear. UCTD is a mild autoimmune condition with generally good outcomes. There is still great uncertainty though regarding diagnosis and management. Going forward, consistent classification criteria are needed to advance UCTD research and eventually provide authoritative guidance on the management of the condition.

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
OBJECTIVES
The aim of this study was to assess the safety and efficacy of long-term low-dose glucocorticoids (GCs) in RA.
METHODS
A protocolised systematic review and meta-analysis (PROSPERO No. CRD42021252528) of double-blind, placebo-controlled randomised trials (RCTs) comparing a low dose of GCs (≤ 7.5mg/day prednisone) to placebo over at least 2 years was performed. The primary outcome investigated was adverse events (AEs). We performed random-effects meta-analyses and used the Cochrane RoB tool and GRADE to assess risk of bias and quality of evidence (QoE).
RESULTS
Six trials with 1078 participants were included. There was no evidence of an increased risk of AEs (incidence rate ratio 1.08; 95% CI 0.86, 1.34; P = 0.52); however, the QoE was low. The risks of death, serious AEs, withdrawals due to AEs, and AEs of special interest did not differ from placebo (very low to moderate QoE). Infections occurred more frequently with GCs (risk ratio 1.4; 1.19-1.65; moderate QoE). Concerning benefit, we found moderate to high quality evidence of improvement in disease activity (DAS28: -0.23; -0.43 to -0.03), function (HAQ -0.09; -0.18 to 0.00), and Larsen scores (-4.61; -7.52 to -1.69). In other efficacy outcomes, including Sharp van der Heijde scores, there was no evidence of benefits with GCs.
CONCLUSION
There is very low to moderate QoE for no harm with long-term low dose GCs in RA, except for an increased risk of infections in GC users. The benefit-risk ratio might be reasonable forusing low-dose long-term GCs considering the moderate to high quality evidence for disease-modifying properties.

Current Rheumatology Reviews Jun 2023Necrotizing scleritis (NS) presents 30%-40% as having a systemic autoimmune condition.
INTRODUCTION
Necrotizing scleritis (NS) presents 30%-40% as having a systemic autoimmune condition.
OBJECTIVE
To present a clinical case report and a systematic review of necrotizing scleritis with ocular manifestation as the first sign of rheumatologic disease.
METHODS
The present study was elaborated according to the rules of CARE.
CASE REPORT
A female patient, 63 years old, a white, administrative assistant, presented irritation, low visual acuity (LVA) in the left eye (LE), and headache. Biomicroscopy (BIO) in the right eye (RE) was normal, and the LE showed hyperemia and scleral thinning. After 1 month, the patient returns without signs of infectious diseases in the exams, and after a rheumatological evaluation with a diagnosis of rheumatoid arthritis, methotrexate and prednisone are prescribed. After 2 months, she relapsed and started treatment with anti-TNF, with remission after the 4th dose. After 1 year, she evolved with LVA in LE.
RESULTS
A total of 244 articles were found, 104 articles were evaluated and 10 were included in the brief review. The symmetrical Funnel Plot does not suggest a risk of bias.
CONCLUSION
Both in the present case report and the literary findings, it was evidenced that the ophthalmologic findings may precede the systemic changes of the disease for the early diagnosis of rheumatoid arthritis.

Review
BACKGROUND
Sjogren's Syndrome (SS) is characterized by xeropthalmia and/or xerostomia. Treating the associated salivary gland hypofunction has been challenging to the clinicians. A variety of topical and systemic therapies have been tried to restore/stimulate the gland function or replace saliva reducing the symptoms of xerostomia and to avoid the problems of diminished salivary flow.
MATERIAL AND METHODS
Four search engines (PUBMED/Medline, EMBASE, Google Scholar and The Cochrane) were used in conducting a systematic review using the terms "Sjogren's syndrome" with the combination of other terms. To define these study acceptability criteria, we used PICO model (Population, Intervention, Control and Outcome) and study design technique.
RESULTS
Out of 47 articles initially screened, 28 studies met our selection criteria. Included studies showed positive results with interventions such as pilocarpine, rituximab, and interferon-alpha (IFN-α) for enhancing salivary flow and lacrimal secretion in SS condition. One study showed promising results for combination of prednisone and hydroxychloroquine in SS, however dose of prednisone is recommended to be tapered. Another study demonstrated comparable effects of dehydroepiandrosterone and the placebo in alleviation of dry mouth symptoms (=0.006). Therapeutic effects have been reported with LASER therapy.
CONCLUSIONS
Pilocarpine was found to be highly beneficial whereas, rituximab and IFN-α were moderately effective in the reduction of hyposalivation in SS patient. Adverse events were common. Use of any alternative modalities for the management cannot be supported based on the current evidence; this demands more studies in future to be conducted staking into account adverse effects which might occur particularly with the pharmacological therapies.

There is limited knowledge in the literature and lack of clear protocols among practitioners regarding preoperative steroids administration for patients undergoing endoscopic sinus surgery (ESS). This study aimed to identify the practice patterns of rhinologists in Saudi Arabia as well as systematically review all health-related evidence regarding the use of preoperative steroids for ESS. A previously used questionnaire was modified and distributed in Saudi Arabia among rhinologists who finished their residency training. It entailed questions about their qualifications and preoperative steroids use, preferred regimen, and possible benefits. Also, a systematic literature review using four major databases was conducted to build a scoping view of the current evidence. A total of 94 subjects responded to the mailed survey. Of them, 72(76.6%) used preoperative steroids; 40 subjects believed that there is a strong supporting evidence while 32 reported that there is no solid evidence. The commonest indication was chronic rhinosinusitis with nasal polyp followed by allergic fungal rhinosinusitis. More than half of subjects (54.2%) preferred medium-dose prednisone (30-40 mg/day). A considerable number believed that steroids decreased surgical bleeding (n = 57, 79.2%), improved surgical field visualization (77.8%), decreased surgical time (77.8%), and decreased mucosal inflammation (61.1%). Thirteen studies including 1028 patients were eligible for the systematic review. Only three studies reported a statistically significant effect of steroids in reducing intraoperative hemorrhage, while only two studies revealed that steroids significantly improved surgical field quality. In two studies, steroids showed a significant effect in reducing eosinophil infiltration. There is a major number of rhinology experts using preoperative steroids for patients undergoing ESS but there is a wide variation among their practice patterns. The current potential advantages of steroids need to be supported by further large randomized clinical trials to establish clear guidelines.
