Abstract
BACKGROUND Thyroid autoimmune disease (TAI) has been verified to be related to multiple adverse pregnancy outcomes. A growing number of evidences highlight the protective roles of glucocorticoid on the treatments of TAI. This meta-analysis aimed to study whether it is beneficial to add glucocorticoid treatment in infertile women with TAI when they are undergoing assisted reproductive technology (ART). METHODS We conducted a systematic search in PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), WanFang database, Weipu China Science and Technology Journal Databases (VIP database) up to September 10, 2020. The Revman 5.3 software was utilized for data statistics. We used a random-effects model to analyze data and the odds ratio (OR) combining with 95% confidence interval (95% CI) were employed to reveal the results. RESULTS Three publications with 237 antithyroid antibody (ATA)-positive and 384 ATA-negative women were included in the final analysis. Overall, glucocorticoid therapy showed satisfying effects on improving clinical pregnancy rate (OR = 4.63, 95% CI [2.23, 9.58], I2 = 0.0%, P < .0001) and live birth rate (OR = 3.19, 95% CI [1.13, 9.04], I2 = 0.0%, P = .03) of ATA-positive women compared with control group. However, it seems that glucocorticoid showed no significant difference in the abortion rate (OR = 0.62, 95% CI [0.09, 4.32], I2 = 35%, P = .64) and oocyte recovery (OR = 2.26, 95% CI [-1.46, 5.99], I2 = 79%, P < .0001) between the 2 groups. CONCLUSIONS Glucocorticoid may improve the pregnancy outcomes of ART women with ATA positive, but there is no significant reduction in the risk of miscarriage. Due to the limited enrolled references, glucocorticoid adjuvant therapy should be applied after more randomized controlled trials.

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH) is an autosomal recessive condition which leads to glucocorticoid deficiency and is the most common cause of adrenal insufficiency in children. In over 90% of cases, 21-hydroxylase enzyme deficiency is found which is caused by mutations in the 21-hydroxylase gene. Managing individuals with CAH due to 21-hydroxylase deficiency involves replacing glucocorticoids with oral glucocorticoids (including prednisolone and hydrocortisone), suppressing adrenocorticotrophic hormones and replacing mineralocorticoids to prevent salt wasting. During childhood, the main aims of treatment are to prevent adrenal crises and to achieve normal stature, optimal adult height and to undergo normal puberty. In adults, treatment aims to prevent adrenal crises, ensure normal fertility and to avoid the long-term consequences of glucocorticoid use. Current glucocorticoid treatment regimens can not optimally replicate the normal physiological cortisol level and over-treatment or under-treatment is often reported. OBJECTIVES To compare and determine the efficacy and safety of different glucocorticoid replacement regimens in the treatment of CAH due to 21-hydroxylase deficiency in children and adults. SEARCH METHODS We searched the Cochrane Inborn Errors of Metabolism Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews, and trial registries (ClinicalTrials.gov and WHO ICTRP). Date of last search of trials register: 24 June 2019. SELECTION CRITERIA Randomised controlled trials (RCTs) or quasi-RCTs comparing different glucocorticoid replacement regimens for treating CAH due to 21-hydroxylase deficiency in children and adults. DATA COLLECTION AND ANALYSIS The authors independently extracted and analysed the data from different interventions. They undertook the comparisons separately and used GRADE to assess the quality of the evidence. MAIN RESULTS Searches identified 1729 records with 43 records subject to further examination. After screening, we included five RCTs (six references) with a total of 101 participants and identified a further six ongoing RCTs. The number of participants in each trial varied from six to 44, with participants' ages ranging from 3.6 months to 21 years. Four trials were of cross-over design and one was of parallel design. Duration of treatment ranged from two weeks to six months per treatment arm with an overall follow-up between six and 12 months for all trials. Overall, we judged the quality of the trials to be at moderate to high risk of bias; with lack of methodological detail leading to unclear or high risk of bias judgements across many of the domains. All trials employed an oral glucocorticoid replacement therapy, but with different daily schedules and dose levels. Three trials compared different dose schedules of hydrocortisone (HC), one three-arm trial compared HC to prednisolone (PD) and dexamethasone (DXA) and one trial compared HC with fludrocortisone to PD with fludrocortisone. Due to the heterogeneity of the trials and the limited amount of evidence, we were unable to perform any meta-analyses. No trials reported on quality of life, prevention of adrenal crisis, presence of osteopenia, presence of testicular or ovarian adrenal rest tumours, subfertility or final adult height. Five trials (101 participants) reported androgen normalisation but using different measurements (very low-quality evidence for all measurements). Five trials reported 17 hydroxyprogesterone (17 OHP) levels, four trials reported androstenedione, three trials reported testosterone and one trial reported dehydroepiandrosterone sulphate (DHEAS). After four weeks, results from one trial (15 participants) showed a high morning dose of HC or a high evening dose made little or no difference in 17 OHP, testosterone, androstenedione and DHEAS. One trial (27 participants) found that HC and DXA treatment suppressed 17 OHP and androstenedione more than PD treatment after six weeks and a further trial (eight participants) reported no difference in 17 OHP between the five different dosing schedules of HC at between four and six weeks. One trial (44 participants) comparing HC and PD found no differences in the values of 17 OHP, androstenedione and testosterone at one year. One trial (26 participants) of HC versus HC plus fludrocortisone found that at six months 17 OHP and androstenedione levels were more suppressed on HC alone, but there were no differences noted in testosterone levels. While no trials reported on absolute final adult height, we reported some surrogate markers. Three trials reported on growth and bone maturation and two trials reported on height velocity. One trial found height velocity was reduced at six months in 26 participants given once daily HC 25 mg/m²/day compared to once daily HC 15 mg/m²/day (both groups also received fludrocortisone 0.1 mg/day), but as the quality of the evidence was very low we are unsure whether the variation in HC dose caused the difference. There were no differences noted in growth hormone or IGF1 levels. The results from another trial (44 participants) indicate no difference in growth velocity between HC and PD at one year (very low-quality evidence), but this trial did report that once daily PD treatment may lead to better control of bone maturation compared to HC in prepubertal children and that the absolute change in bone age/chronological age ratio was higher in the HC group compared to the PD group. AUTHORS' CONCLUSIONS There are currently limited trials comparing the efficacy and safety of different glucocorticoid replacement regimens for treating 21-hydroxylase deficiency CAH in children and adults and we were unable to draw any firm conclusions based on the evidence that was presented in the included trials. No trials included long-term outcomes such as quality of life, prevention of adrenal crisis, presence of osteopenia, presence of testicular or ovarian adrenal rest tumours, subfertility and final adult height. There were no trials examining a modified-release formulation of HC or use of 24-hour circadian continuous subcutaneous infusion of hydrocortisone. As a consequence, uncertainty remains about the most effective form of glucocorticoid replacement therapy in CAH for children and adults. Future trials should include both children and adults with CAH. A longer duration of follow-up is required to monitor biochemical and clinical outcomes.

Tallouzi, MO, Moore, DJ, Barry, RJ, Calvert, M, Mathers, J, Murray, PI, Denniston, AK
Ocular immunology and inflammation. 2019;(4):658-680
Abstract
Purpose: To conduct a systematic review of effectiveness of pharmacological therapies for treatment of Uveitic Macular Edema (UMO). Method/Design: Comparative studies of pharmacological therapies in patients with UMO were identified in Cochrane CENTRAL/MEDLINE/EMBASE/CINAHL/trials registers (February 2017). PROSPERO registration: CRD42015019170. Results: Thirty-one studies were included. Corticosteroids were the most frequently studied (n = 20). Corticosteroids (all forms) were consistently of greater/equal efficacy to active comparators; for anti-VEGF (n = 4) improvement, best-corrected visual acuity (BCVA) and central macular thickness (CMT) were mostly less than local corticosteroid injection; for interferon (n = 1) improvement BCVA and CMT were greater than the comparator of methotrexate; for topical indomethacin (n = 1) improvement, BCVA and CMT were greater than placebo. Non-steroidal anti-inflammatory drugs, carbonic anhydrase inhibitors, and vitamin E (n = 5) were not effective for these outcomes. Conclusion: The review highlights areas where the evidence base is still lacking, and appropriately focused trials are needed to inform best treatment to tackle this sight-threatening condition.

Abstract
BACKGROUND Many studies have examined the effects of exclusive enteral nutrition (EEN) in children with Crohn's disease (CD), but corticosteroids are considered a superior therapy and are frequently used in China. This meta-analysis aims to compare the efficacy of EEN with corticosteroids in treating pediatric CD. METHODS A comprehensive retrieval from medical databases, including PubMed, EMBASE, MEDLINE, Web of Science, Wanfang data, VIP and CNKI, was performed using the search terms "diet therapy", "exclusive enteral nutrition", "Crohn's disease", "inflammatory bowel diseases", "child" and "pediatrics" from January 1990 to April 2017. RESULTS We included 18 studies from 1329 identified sources in this meta-analysis. EEN was as effective as corticosteroids in inducing remission rate of children suffering from CD (OR = 1.35; 95% CI 0.90, 2.10; P = 0.14). Nevertheless, patients who received EEN were more likely to achieve both endoscopic mucosal healing (OR = 5.24; 95% CI 2.06, 13.37; P = 0.0005) and histological mucosal healing (OR = 4.78; 95% CI 1.89, 12.08; P = 0.0009) than those who received corticosteroids; the Pediatric Crohn's Disease Activity Index was lower [mean difference (MD) = - 3.67; 95% CI - 4.91, - 2.43] and weight gain was higher (MD = 1.92; 95% CI 0.02, 3.83; P = 0.05) in those patients who received EEN than in those who received corticosteroids. No difference was found in relapse rate (OR = 0.57; 95% CI 0.25, 1.29; P = 0.18), height for age or body mass index between the patients treated with EEN and corticosteroids at the 1-year end point. CONCLUSIONS This meta-analysis reveals that there is no significant difference between EEN and corticosteroids in the efficacy of inducing remission rate of CD in a pediatric population, but EEN is superior to corticosteroids in improving short-term mucosal inflammation and reducing the PCDAI index.

Abstract
BACKGROUND Glucocorticoid (GC)-induced osteoporosis and fractures have become a serious problem for Eastern Asians. Bisphosphonates (BPs), vitamin D and a combination treatment are effective methods to prevent and treat GC-induced osteoporosis. OBJECTIVE The study aimed to compare the efficacy of BPs, vitamin D and a combination treatment for preventing and managing GC-induced osteoporosis in Eastern Asians. METHODS A comprehensive search in the PubMed, EMBASE, Web of Science and Cochrane CENTRAL databases was undertaken for randomized controlled trials (RCTs) on the effect of BPs, vitamin D and the combination treatment on GCs-induced osteoporosis in Eastern Asian populations. Primary outcome measures were the change in bone mineral density (BMD) and bone turnover markers. The final search was performed in March 2019. RESULTS Nine RCTs were included. A total of 545 patients met the inclusion criteria. Compared with vitamin D, BPs and the combination treatment significantly alleviated osteoporosis of the spine and femoral neck in Eastern Asians with GC-induced osteoporosis. At the same time, the change in serum bone-specific alkaline phosphatase (BAP) and serum C-telopeptide of type I collagen (CTX) levels was observed to be significantly less with BPs and the combination treatment with vitamin D alone. No significant difference was found between BPs and the combination treatment in the markers mentioned above. CONCLUSION Compared with vitamin D alone, BPs alone and the combination treatment were significantly effective on Eastern Asians with GC-induced osteoporosis. Compared with the combination treatment, BPs alone were observed to be effective enough to increase the BMDs of the spine and femoral neck on both sides and thus prevent GC-induced osteoporosis in Eastern Asians.

Abstract
BACKGROUND The combination of steroid and anti-vascular endothelial growth factor (VEGF) intravitreal therapeutic agents could potentially have synergistic effects for treating diabetic macular oedema (DMO). On the one hand, if combined treatment is more effective than monotherapy, there would be significant implications for improving patient outcomes. Conversely, if there is no added benefit of combination therapy, then people could be potentially exposed to unnecessary local or systemic side effects. OBJECTIVES To assess the effects of intravitreal agents that block vascular endothelial growth factor activity (anti-VEGF agents) plus intravitreal steroids versus monotherapy with macular laser, intravitreal steroids or intravitreal anti-VEGF agents for managing DMO. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2018, Issue 1); Ovid MEDLINE; Ovid Embase; LILACS; the ISRCTN registry; ClinicalTrials.gov and the ICTRP. The date of the search was 21 February 2018. SELECTION CRITERIA We included randomised controlled trials (RCTs) of intravitreal anti-VEGF combined with intravitreal steroids versus intravitreal anti-VEGF alone, intravitreal steroids alone or macular laser alone for managing DMO. We included people with DMO of all ages and both sexes. We also included trials where both eyes from one participant received different treatments. DATA COLLECTION AND ANALYSIS We used standard methodological procedures recommended by Cochrane.Two authors independently reviewed all the titles and abstracts identified from the electronic and manual searches against the inclusion criteria. Our primary outcome was change in best corrected visual acuity (BCVA) between baseline and one year. Secondary outcomes included change in central macular thickness (CMT), economic data and quality of life. We considered adverse effects including intraocular inflammation, raised intraocular pressure (IOP) and development of cataract. MAIN RESULTS There were eight RCTs (703 participants, 817 eyes) that met our inclusion criteria with only three studies reporting outcomes at one year. The studies took place in Iran (3), USA (2), Brazil (1), Czech Republic (1) and South Korea (1). Seven studies used the unlicensed anti-VEGF agent bevacizumab and one study used licensed ranibizumab. The study that used licensed ranibizumab had a unique design compared with the other studies in that included eyes had persisting DMO after anti-VEGF monotherapy and received three monthly doses of ranibizumab prior to allocation. The anti-VEGF agent was combined with intravitreal triamcinolone in six studies and with an intravitreal dexamethasone implant in two studies. The comparator group was anti-VEGF alone in all studies; two studies had an additional steroid monotherapy arm, another study had an additional macular laser photocoagulation arm. Whilst we judged these studies to be at low risk of bias for most domains, at least one domain was at unclear risk in all studies.When comparing anti-VEGF/steroid with anti-VEGF monotherapy as primary therapy for DMO, we found no meaningful clinical difference in change in BCVA (mean difference (MD) -2.29 visual acuity (VA) letters, 95% confidence interval (CI) -6.03 to 1.45; 3 RCTs; 188 eyes; low-certainty evidence) or change in CMT (MD 0.20 μm, 95% CI -37.14 to 37.53; 3 RCTs; 188 eyes; low-certainty evidence) at one year. There was very low-certainty evidence on intraocular inflammation from 8 studies, with one event in the anti-VEGF/steroid group (313 eyes) and two events in the anti-VEGF group (322 eyes). There was a greater risk of raised IOP (Peto odds ratio (OR) 8.13, 95% CI 4.67 to 14.16; 635 eyes; 8 RCTs; moderate-certainty evidence) and development of cataract (Peto OR 7.49, 95% CI 2.87 to 19.60; 635 eyes; 8 RCTs; moderate-certainty evidence) in eyes receiving anti-VEGF/steroid compared with anti-VEGF monotherapy. There was low-certainty evidence from one study of an increased risk of systemic adverse events in the anti-VEGF/steroid group compared with the anti-VEGF alone group (Peto OR 1.32, 95% CI 0.61 to 2.86; 103 eyes).One study compared anti-VEGF/steroid versus macular laser therapy. At one year investigators did not report a meaningful difference between the groups in change in BCVA (MD 4.00 VA letters 95% CI -2.70 to 10.70; 80 eyes; low-certainty evidence) or change in CMT (MD -16.00 μm, 95% CI -68.93 to 36.93; 80 eyes; low-certainty evidence). There was very low-certainty evidence suggesting an increased risk of cataract in the anti-VEGF/steroid group compared with the macular laser group (Peto OR 4.58, 95% 0.99 to 21.10, 100 eyes) and an increased risk of elevated IOP in the anti-VEGF/steroid group compared with the macular laser group (Peto OR 9.49, 95% CI 2.86 to 31.51; 100 eyes).One study provided very low-certainty evidence comparing anti-VEGF/steroid versus steroid monotherapy at one year. There was no evidence of a meaningful difference in BCVA between treatments at one year (MD 0 VA letters, 95% CI -6.1 to 6.1, low-certainty evidence). Likewise, there was no meaningful difference in the mean CMT at one year (MD - 9 μm, 95% CI -39.87μm to 21.87μm between the anti-VEGF/steroid group and the steroid group. There was very low-certainty evidence on raised IOP at one year comparing the anti-VEGF/steroid versus steroid groups (Peto OR 0.75, 95% CI 0.16 to 3.55).No included study reported impact of treatment on patients' quality of life or economic data. None of the studies reported any cases of endophthalmitis. AUTHORS' CONCLUSIONS Combination of intravitreal anti-VEGF plus intravitreal steroids does not appear to offer additional visual benefit compared with monotherapy for DMO; at present the evidence for this is of low-certainty. There was an increased rate of cataract development and raised intraocular pressure in eyes treated with anti-VEGF plus steroid versus anti-VEGF alone. Patients were exposed to potential side effects of both these agents without reported additional benefit. The majority of the evidence comes from studies of bevacizumab and triamcinolone used as primary therapy for DMO. There is limited evidence from studies using licensed intravitreal anti-VEGF agents plus licensed intravitreal steroid implants with at least one year follow-up. It is not known whether treatment response is different in eyes that are phakic and pseudophakic at baseline.

Abstract
INTRODUCTION The aim of this study was to explore the effect of maternal fluorinated steroid therapy on fetuses affected by second-degree immune-mediated congenital atrioventricular block. MATERIAL AND METHODS Studies reporting the outcome of fetuses with second-degree immune-mediated congenital atrioventricular block diagnosed on prenatal ultrasound and treated with fluorinated steroids compared with those not treated were included. The primary outcome was the overall progression of congenital atrioventricular block to either continuous or intermittent third-degree congenital atrioventricular block at birth. Meta-analyses of proportions using random effect model and meta-analyses using individual data random-effect logistic regression were used. RESULTS Five studies (71 fetuses) were included. The progression rate to congenital atrioventricular block at birth in fetuses treated with steroids was 52% (95% confidence interval 23-79) and in fetuses not receiving steroid therapy 73% (95% confidence interval 39-94). The overall rate of regression to either first-degree, intermittent first-/second-degree or sinus rhythm in fetuses treated with steroids was 25% (95% confidence interval 12-41) compared with 23% (95% confidence interval 8-44) in those not treated. Stable (constant) second-degree congenital atrioventricular block at birth was present in 11% (95% confidence interval 2-27) of cases in the treated group and in none of the newborns in the untreated group, whereas complete regression to sinus rhythm occurred in 21% (95% confidence interval 6-42) of fetuses receiving steroids vs. 9% (95% confidence interval 0-41) of those untreated. CONCLUSIONS There is still limited evidence as to the benefit of administered fluorinated steroids in terms of affecting outcome of fetuses with second-degree immune-mediated congenital atrioventricular block.

Abstract
BACKGROUND This is an update of a review published in 2012. A related review "Inhaled versus systemic corticosteroids for preventing bronchopulmonary dysplasia in ventilated very low birth weight preterm neonates" has been updated as well. Bronchopulmonary dysplasia (BPD) is a serious and common problem among very low birth weight infants, despite the use of antenatal steroids and postnatal surfactant therapy to decrease the incidence and severity of respiratory distress syndrome. Due to their anti-inflammatory properties, corticosteroids have been widely used to treat or prevent BPD. However, the use of systemic steroids has been associated with serious short- and long-term adverse effects. Administration of corticosteroids topically through the respiratory tract may result in beneficial effects on the pulmonary system with fewer undesirable systemic side effects. OBJECTIVES To compare the effectiveness of inhaled versus systemic corticosteroids administered to ventilator-dependent preterm neonates with birth weight ≤ 1500 g or gestational age ≤ 32 weeks after 7 days of life on the incidence of death or BPD at 36 weeks' postmenstrual age. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2017, Issue 1), MEDLINE via PubMed (1966 to 23 February 2017), Embase (1980 to 23 February 2017), and CINAHL (1982 to 23 February 2017). We also searched clinical trials registers, conference proceedings and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing inhaled versus systemic corticosteroid therapy (irrespective of dose and duration) starting after the first week of life in ventilator-dependent very low birth weight infants. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by the Cochrane Collaboration. MAIN RESULTS We included three trials that involved a total of 431 participants which compared inhaled versus systemic corticosteroids to treat BPD. No new trials were included for the 2017 update.Although one study randomised infants at < 72 hours (N = 292), treatment started when infants were aged > 15 days. In this larger study, deaths were included from the point of randomisation and before treatment started. Two studies (N = 139) randomised and started treatment at 12 to 21 days.Two trials reported non-significant differences between groups for the primary outcome: incidence of death or BPD at 36 weeks' postmenstrual age among all randomised infants. Estimates for the largest trial were Relative risk (RR) 1.04 (95% Confidence interval (CI) 0.86 to 1.26), Risk difference (RD) 0.03 (95% CI -0.09 to 0.15); (moderate-quality evidence). Estimates for the other trial reporting the primary outcome were RR 0.94 (95% CI 0.83 to 1.05), RD -0.06 (95% CI -0.17 to 0.05); (low-quality evidence).Secondary outcomes that included data from all three trials showed no significant differences in the duration of mechanical ventilation or supplemental oxygen, length of hospital stay, or the incidence of hyperglycaemia, hypertension, necrotising enterocolitis, gastrointestinal bleed, retinopathy of prematurity or culture-proven sepsis moderate- to low-quality evidence).In a subset of 75 surviving infants who were enrolled from the United Kingdom and Ireland, there were no significant differences in developmental outcomes at seven years of age between groups (moderate-quality evidence). One study received grant support and the industry provided aerochambers and metered dose inhalers of budesonide and placebo for the same study. No conflict of interest was identified. AUTHORS' CONCLUSIONS We found no evidence that inhaled corticosteroids confer net advantages over systemic corticosteroids in the management of ventilator-dependent preterm infants. There was no evidence of difference in effectiveness or adverse event profiles for inhaled versus systemic steroids.A better delivery system guaranteeing selective delivery of inhaled steroids to the alveoli might result in beneficial clinical effects without increasing adverse events.To resolve this issue, studies are needed to identify the risk/benefit ratio of different delivery techniques and dosing schedules for administration of these medications. The long-term effects of inhaled steroids, with particular attention to neurodevelopmental outcomes, should be addressed in future studies.

Khan, Z, Kuriakose, RK, Khan, M, Chin, EK, Almeida, DR
Ophthalmic surgery, lasers & imaging retina. 2017;(2):160-166
Abstract
BACKGROUND AND OBJECTIVE To assess the effect on best-corrected visual acuity (BCVA) and efficacy of the intravitreal sustained-release 0.7 mg dexamethasone implant (Ozurdex; Allergan, Irvine, CA) in patients with recalcitrant diabetic macular edema (DME). PATIENTS AND METHODS Meta-analysis utilizing the MOOSE framework and a random effects model. Studies included adults undergoing treatment with Ozurdex for DME. The methodologic quality of each study was assessed using the MINORS and the Cochrane Collaboration Risk of Bias for randomized studies. RESULTS A total of 3,859 patients among 15 studies were included in the final analysis. The mean difference in BCVA was a gain of four lines or 20 Early Treatment of Diabetic Retinopathy Study letters with Ozurdex at a mean follow-up period of 6 months. CONCLUSIONS Treatment with Ozurdex is associated with significant mean improvement in visual acuity. Clinicians should have a multimodality approach to treating DME and be aware of this treatment option in those who have a suboptimal response to anti-VEGF therapy.
