Meta-Analysis Review
Systematic Review and Network Meta-Analysis of Treatments for Chemotherapy-Naive Patients with Asymptomatic/Mildly Symptomatic Metastatic Castration-Resistant Prostate Cancer.
OBJECTIVES
To estimate the relative effectiveness of enzalutamide in chemotherapy-naive metastatic castration-resistant prostate cancer by conducting a systematic literature review and a network meta-analysis (NMA).
METHODS
A systematic literature review identified randomized controlled trials comparing enzalutamide, abiraterone/prednisone, radium-223, sipuleucel-T, or docetaxel with each other or placebo in chemotherapy-naive or mixed populations (with and without prior chemotherapy) with asymptomatic/mildly symptomatic metastatic castration-resistant prostate cancer. Feasibility assessment evaluated the trials' suitability for NMA inclusion. The main outcomes were hazard ratios (HRs) for overall survival (OS) and radiographic progression-free survival (rPFS).
RESULTS
Searches of relevant bibliographic databases, trial registers, Web sites, and conference abstracts conducted in October 2014 identified 25,712 records. Ten randomized controlled trials were eligible for the NMA. Enzalutamide was superior to placebo for OS and rPFS (fixed-effects model). NMA results (fixed-effects model) showed no evidence of a difference between enzalutamide and abiraterone/prednisone (HR 0.95 [95% CrI 0.77-1.16]), sipuleucel-T (HR 1.07 [95% CrI 0.84-1.37]), or radium-223 (HR 1.10 [95% CrI 0.87-1.37]) for OS. HRs were similar for the random-effects model. Nevertheless, results (fixed-effects model) suggested that enzalutamide was superior to abiraterone/prednisone (HR 0.59 [95% CrI 0.48-0.72]) and sipuleucel-T (HR 0.32 [95% CrI 0.25-0.42]) for rPFS. Results also suggested superiority of enzalutamide versus placebo, abiraterone/prednisone, or sipuleucel-T for time to chemotherapy.
CONCLUSIONS
For rPFS, the NMA suggests that enzalutamide is superior to abiraterone/prednisone and sipuleucel-T. There is no evidence of a statistically significant difference in OS between enzalutamide and abiraterone/prednisone, sipuleucel-T, or radium-223. Given the limitations in network construction and underlying assumptions made to complete these analyses, results should be interpreted with caution.

Review
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease involving multiple systems with a range of clinical presentations caused by the production of antibodies, activation of complements, and deposition of immune complexes. The exact cause of SLE is still unknown. The effectiveness of traditional treatment methods for SLE is very little. Nowadays, resistance to conventional therapy, steroids, and immunosuppressants is common among SLE patients. Patients with refractory disease and nephritis generally have severe drug-induced toxicity which contributes to organ dysfunction, despite available therapies. Different biologic agents and therapeutic antibodies have become an alternative and have been under experiment in clinical trials, enrolling patients whose disease is inadequately controlled by conventional treatment. Belimumab is the only targeted therapy approved for SLE treatment. This systematic review discusses one such biological agent for treating systemic lupus erythematosus, namely, belimumab. The systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies included randomized clinical trials (RCTs) from 2005 to 2021 on adult SLE. patients treated with monoclonal antibodies to assess the efficacy and safety. Methodological quality was assessed using PubMed, PMC, the Cochrane Risk of Bias tool, and the QUality In Prognosis Studies Tool (QUIPS) for RCTs. Two independent reviewers performed an electronic search on MEDLINE, Cochrane Library, SCIELO, Scopus, and ResearchGate. Based on a systematic review of articles we found that belimumab appears to be efficacious and generally well-tolerated in the treatment of SLE as compared to other drugs. The long-term use of belimumab combined with standard therapy showed a low incidence of organ damage. A lower incidence of organ damage was seen after initiating treatment in patients with a high risk for organ dysfunction. Patients who test for antinuclear antibody or anti-dsDNA-positive SLE, with moderate symptoms in the skin and musculoskeletal systems despite immunosuppressants, are treated with belimumab as an adjunct therapy. Patients with severe lupus nephritis or active CNS lupus cannot be treated with belimumab. Belimumab is effective in most races, as a clinical trial done in North-East Asia showed improvement in SLE symptoms and decreased dependence on prednisone. Belimumab also decreased disease activity and severe flares. Belimumab had greater efficacy in children.

Meta-Analysis Review
BACKGROUND
Central post-stroke pain (CPSP) is a common condition. Several pharmacotherapies have been applied in practice. However, the comparative effectiveness among these pharmacotherapies is unknown.
AIM
The aim of this study is to study the comparative effectiveness among differential pharmacotherapies for CPSP through a network meta-analysis.
METHODS
We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science from inception to 30 March 2022, without any language restriction. Two reviewers independently screened the retrieved articles, extracted data, and evaluated the risk of bias (RoB). The outcome of interest of the study was the change in the scores of pain intensity scales. We estimated standard mean differences (SMDs) between treatments and calculated corresponding 95% CIs.
RESULTS
Thirteen randomized controlled trials (529 participants) were included after a screen of 1774 articles. Compared with placebo, pamidronate (SMD -2.43, 95% CI -3.54 to -1.31; - score = 0.93), prednisone (SMD -2.38, 95% CI -3.09 to -1.67; - score = 0.92), levetiracetam (SMD -2.11, 95% CI -2.97 to -1.26; - score = 0.87), lamotrigine (SMD -1.39, 95% CI -2.21 to -0.58; - score = 0.73), etanercept (SMD -0.92, 95% CI -1.8 to -0.03; - score = 0.59), and pregabalin (SMD -0.46, 95% CI -0.71 to -0.22; - score = 0.41) had significantly better treatment effect. Pamidronate, prednisone, and levetiracetam ranked as the first three most effective treatments. In subgroup analyses, prednisone, levetiracetam, lamotrigine, and pregabalin were more effective than placebo as oral pharmacotherapies, while etanercept was more effective than placebo as injectable pharmacotherapy.
CONCLUSIONS
Our study confirmed that pamidronate, prednisone, and guideline-recommended anticonvulsants were effective for reducing pain intensity for CPSP. Pamidronate and prednisone showed better effect than other pharmacotherapies, which warrants further investigation.

Meta-Analysis
BACKGROUND
Chronic histiocytic intervillositis (CHI) is a rare placental lesion with a high recurrence rate and poor perinatal outcomes. There are currently limited guidelines regarding the diagnosis of this condition in the index pregnancy and treatment where recurrence is suspected.
OBJECTIVE
The primary objective of this systematic review and meta-analysis was to determine the perinatal outcomes of pregnancies affected by chronic histiocytic intervillositis and to what extent they can be improved with treatment. The secondary objective was to assess the relationship between CHI lesion severity and pregnancy loss.
METHODS
A systematic search of Ovid Embase, Web of Science, Science Direct, PubMed, Ovid Medline, Google Scholar and CINAHL was carried out. Case reports, cohort, case-control and randomised controlled trials (RCT) detailing the perinatal outcomes of CHI pregnancies, both treated and untreated, were included.
RESULTS
No RCTs were identified. However, in a review population of 659 pregnancies, with additional 7 in case reports, CHI treatments included aspirin, prednisone, prednisolone, low molecular weight heparin (LMWH), hydroxychloroquine and adalimumab. A descriptive synthesis of data found mixed results for treatments in relation to live birth, miscarriage and fetal growth restriction outcomes. Furthermore, quantitative synthesis of 38 pregnancies revealed a non-significant improvement in live birth rate with CHI targeted treatment (OR 1.79 [95% CI 0.33-9.61] (p=0.50), while meta-analysis of CHI severity in line with pregnancy loss, in a sample of 231 pregnancies, revealed lower odds of pregnancy loss with less severe lesions (OR: 0.17 [0.03-0.80], p=0.03).
CONCLUSIONS
This systematic review and meta-analysis reinforce notions surrounding the insufficient evidence for CHI treatment. It also strengthens previous hypotheses detailing the positive association between CHI lesion severity and odds of pregnancy loss. Aspirin, LMWH, prednisolone, hydroxychloroquine and adalimumab are candidates with varying levels of weak to moderate evidence supporting their use. Further prospective research is required to obtain robust evidence pertaining to treatment safety and efficacy and optimal drug regimes.

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.

Immunoglobulin G4 (IgG4)-positive marginal zone lymphoma (MZL) is rare and undefined. It is unclear whether IgG4-positive MZLs have as favorable an outcome as MZLs in general. Also, correlation with IgG4-related disease (IgG4-RD) and IgG4-positive MZLs is unknown. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews, we searched MEDLINE and EMBASE for all peer-reviewed articles using keywords including"IgG4" and "marginal zone lymphoma" from their inception to February 20, 2022. Twenty-two articles, including six observational studies and 24 cases from 16 case reports and case series, were included. Only one study had a comparative group, and the other five were exploratory observational studies. IgG4-positive MZLs commonly occurred in males (83.3%). It primarily involved ocular adnexa (41.7%) and skin (29.2%). Only 29.2% had concurrent IgG4-RD, and no expiration was noted. While most cases were treated with excision, resection, or clinical observation, 21.7% received rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone as a first-line treatment. This systematic review summarizes the current understanding of the characteristics of IgG4-positive MZLs. While there seems to be IgG4-RD-related and de novo IgG4-positive MZLs, future research needs to clearly define MZL with polyclonal IgG4-positive cells and IgG4-producing lymphoma. Further studies are critical to clarifying long-term prognosis and optimal surveillance planning.

BACKGROUND
Micropapular cutaneous sarcoidosis (MPCS) is a rare variant of sarcoidosis. Herein we review the literature and include a recent case of MPCS discussing pathogenesis, diagnosis, treatment, and prognosis.
METHOD
A review was conducted using the terms "micropapular sarcoidosis" and "micropapular sarcoid." A recent case of a 50-year-old male patient with biopsy-identified MPCS was also included in the review.
RESULTS
In total, 12 cases with an aggregate of 18 patients were included in the review. Presentation among all patients was consistent, with scattered, occasionally pruritic, faintly erythematous shiny white papules. Skin biopsy demonstrated noncaseating granulomas. Systemic prednisone, oxytetracycline, and hydroxychloroquine, as well as topical betamethasone, were used for therapy.
CONCLUSION
In our review there does not seem to be a clear link as to the definite cause of the MPCS. While the relationships to tuberculosis and autoimmunity seem to be often emphasized, there was no clear association with either etiology.

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.

Background Ribbing disease, or multiple diaphyseal sclerosis, is a rare benign bone dysplasia. Purpose To systematically review the literature to determine the clinical and radiological presentation of patients with Ribbing disease as well as the effects of attempted treatments. Material and Methods We considered individual patient data of patients diagnosed with Ribbing disease derived from patient reports and patient series. All stages of the review were performed by two reviewers independently. Standard descriptive statistics were used for quantitative analyses and mixed model analyses were used when appropriate Results The literature search yielded 420 unique hits of which 23 studies were included, covering a total of 40 patients of whom 29 had bilateral involvement. The mean age at diagnosis was 35 years and the mean time between diagnosis and onset of symptoms, mostly pain, was five years (range = 1-16 years). The tibial diaphysis was the most commonly involved bone in 35 of 36 patients. Non-surgical treatment consisted of non-steroidal anti-inflammatory drugs (NSAIDs), prednisone, and bisphophonates with mixed results. Surgical treatment consisted of intramedullary reaming and fenestration and was very effective to reduce pain. Conclusion The clinical presentation and imaging findings of patients with Ribbing disease are becoming more apparent. However, there is paucity of evidence on the natural disease progression and effectiveness of treatment modalities.

Clinical Nephrology Apr 2022The aim of this study was to analyze the clinical features, risk factors, and outcomes of patients with primary nephrotic syndrome (PNS) who developed (PCP).
OBJECTIVE
The aim of this study was to analyze the clinical features, risk factors, and outcomes of patients with primary nephrotic syndrome (PNS) who developed (PCP).
MATERIALS AND METHODS
We systematically reviewed medical records from 18 PNS patients with PCP admitted to our hospital from April 2007 to April 2019. A total of 180 cases were randomly selected as controls from PNS inpatients without infection.
RESULTS
In PCP patients, the mean age at presentation was 48.5 years, mean duration of prednisone treatment was 3.7 months, and mean prednisone dose on admission was 31.3 mg/d. Eight patients (44.4%) had coexisting infections, most often was (4 patients); 11 patients (61.1%) had ICU admission, and 9 patients (50%) had mechanical ventilation. PCP patients had more prednisone, more immunosuppressive therapy, lower CD4+ cell counts and hemoglobin, and higher serum creatinine than those without infections (p < 0.05). All patients survived after treatment.
CONCLUSION
PCP was not unusual in PNS patients, and the most important risk factors were prednisone usage, other immunosuppressive therapy, and a lower CD4+ cell count; however, these patients had a good outcome after sufficient treatment.
