PURPOSE
The aim of the study is to report a systematic review (from 2000 to 2017) of all pediatric cases of vulvar Crohn's disease (VCD) and to highlight the key-points for a correct diagnosis and management of this rare condition.
METHODS
An electronic search using the Pubmed/Medline, Scopus, EMBASE, Cochrane database and Google Scholar database was performed according to PRISMA guidelines.
RESULTS
Twenty pediatric studies and 22 cases of VCD were included for analysis. All the articles reported a single case, except two articles where two cases, respectively, are described. Clinical vulvar examination showed the following main manifestations: vulvar erythema (9/22 cases, 40.9%), vulvar swelling (8/22 cases, 36.4%), vulvar edema (8/22 cases, 36.4%), vulvar ulcers (4/22 cases, 18.2%). Perianal and/or anal involvement (fissures, vegetations, skin tags, erythema, papules, nodules) were recorded in ten cases (45.4%). Steroids per os and/or topical administration were the most prescribed treatment, achieving clinical remission in 11 cases (50%), used alone or in combination with metronidazole or 5-aminosalicylic acid, azathioprine or sulphasalazine/mesalazine.
CONCLUSIONS
This review shows that pediatric VCD is an uncommon disease, difficult to be diagnosed as either symptoms or clinical lesions are not specific. A multidisciplinary approach is advised to reach a correct diagnosis and plan clinical treatment.

Meta-Analysis
BACKGROUND
Dysregulation of several inflammatory cytokines including tumour necrosis factor (TNF) in dementia patients has also been identified as a key factor in the pathogenesis of rheumatoid arthritis (RA). We aimed to investigate the association of disease-modifying antirheumatic drugs (DMARDs) therapy for RA with risk of incident dementia.
METHODS
Electronic database searches of PubMed, EMBASE and Cochrane Library were performed. Observational studies that assessed the association of dementia with DMARDs in RA were included. Pooled risk ratios (RRs) with 95% CIs were used as summary statistic. The certainty of evidence was judged by using the Grading of Recommendations Assessment, Development and Evaluation system.
RESULTS
Overall, 14 studies involving 940 442 patients with RA were included. Pooled RR for developing dementia was 0.76 (95% CI 0.72 to 0.80) in patients taking biological DMARDs overall versus those taking conventional synthetic DMARDs, with 24% for TNF inhibitors (RR 0.76, 95% CI 0.71 to 0.82), 24% for non-TNF biologics (RR 0.76, 95% CI 0.70 to 0.83), separately. There was a significant subgroup effect among different types of TNF inhibitors (RR 0.58 [95%CI 0.53 to 0.65], 0.65 [95% CI 0.59 to 0.72], 0.80 [95% CI 0.72 to 0.88] for etanercept, adalimumab, infliximab, respectively; p value between groups=0.002). However, compared with non-users of DMARDs or investigative treatment, no significant effect on dementia incidence was observed in those receiving conventional synthetic DMARDs overall (RR 0.84, 95% CI 0.59 to 1.20), methotrexate (RR 0.78, 95% CI 0.54 to 1.12), hydroxychloroquine (RR 0.95, 95% CI 0.63 to 1.44), except for sulfasalazine (RR 1.27, 95% CI 1.06 to 1.50).
CONCLUSIONS
Biological DMARDs for RA are associated with decreased dementia risk, while protective effect is not observed in conventional synthetic DMARDs. Controlled clinical trials on TNF inhibitors are necessary to test their neuroprotective potentials.

AIM
To assess the effects of probiotic Medilac-S as adjunctive therapy for the induction of remission of ulcerative colitis (UC) in a Chinese population through a systematic review and meta-analysis.
METHODS
A systematic literature search was conducted to find randomized, controlled trials in a Chinese population with at least two study arms - a control arm which receives a conventional, oral aminosalicylate drug, and a treatment arm, which administers the same conventional drug in conjunction with the probiotic Medilac-S . Both English and Chinese databases were searched, including PubMed, EMBASE, Google Scholar, Chinese National Knowledge Infrastructure, Wanfang Data, and VIP Search, and study data was extracted onto standardized abstraction sheets. Meta-analyses were conducted for primary and secondary outcomes of interest using a fixed or random effects model. The primary outcome was the induction of clinical remission and the secondary outcomes included changes in Sutherland index, endoscopic and histological scores, proportion of reported clinical symptoms and adverse events (AEs). For outcomes with sufficient data, the type of conventional drug therapy was also assessed to determine if the effects of combination therapy with Medilac-S was influenced by drug type. All tests were conducted using a type I error rate of 0.05 and all confidence intervals (CI) were based on a 95% confidence level. Review protocol was uploaded to PROSPERO (CRD42018085658 upon completion).
RESULTS
Fifty-three clinical trials with a total of 3984 participants were identified and included in the review. Medilac-S adjunctive therapy significantly improved induction of clinical remission (RR = 1.21; 95%CI: 1.18-1.24; < 0.0001) with the estimated likelihood of effective treatment, on average, 21% higher for those consuming the probiotic. Sutherland index scores showed the control mean was on average 3.10 (CI: 2.41-3.78; = 0.0428) units greater than the treatment mean, thereby demonstrating significant improvement in participants taking the probiotic. Similarly, a significant difference was seen between the overall reduction of endoscopic and histological scores of control and treatment arm participants, with score decreases in the control groups 0.71 (CI: 0.3537-1.0742) and 1.1 (CI: 0.9189-1.2300) units smaller than treatment group score decreases. The proportion of participants reporting clinical symptoms, (abdominal pain, tenesmus, blood and mucous in stool, and diarrhea) was significantly reduced after combination therapy with Medilac-S ( < 0.0001) and estimated to be on average 44% (RR = 0.44, CI: 0.32-0.59), 53% (RR = 0.53, CI: 0.38-74), 40% (RR = 0.40, CI: 0.28-0.58) and 47% (RR = 0.47 CI: 0.36-0.42) respectively, of the proportion of individuals reporting the aforementioned symptoms after conventional therapy alone. The risk of AEs was also significantly reduced with adjunctive Medilac-S therapy. The proportion of individuals in the treatment groups reporting AEs was an estimated 72% of the proportion of individuals in the control groups reporting AEs (RR = 0.72, CI: 0.55-0.94, = 0.0175). Upon comparing effect means for different drug types in conjunction with Medilac-S, evidence of significant variability ( < 0.0001) was observed, and sulfasalazine was found to be the most effective drug in both primary and secondary outcomes.
CONCLUSION
Evidence suggests Medilac-S adjunctive therapy should be considered standard care for UC in a Chinese population because it aids in the induction of clinical remission, improves symptoms of the gastrointestinal tract and reduces risk of AEs.

BACKGROUND
Crohn's disease (CD) is a chronic disease of the gut. About 75% of people with CD undergo surgery at least once in their lifetime to induce remission. However, as there is no known cure for the disease, patients usually experience a recurrence even after surgery. Different interventions are routinely used in maintaining postsurgical remission. There is currently no consensus on which treatment is the most effective.
OBJECTIVES
To assess the effects and harms of interventions for the maintenance of surgically induced remission in Crohn's disease and rank the treatments in order of effectiveness.
SEARCH METHODS
We searched the Cochrane IBD Group Specialized Register, CENTRAL, MEDLINE, and Embase from inception to 15 January 2019. We also searched reference lists of relevant articles, abstracts from major gastroenterology meetings, ClinicalTrials.gov, and the WHO ICTRP. There was no restriction on language, date, or publication status.
SELECTION CRITERIA
We considered for inclusion randomised controlled trials (RCTs) that compared different interventions used for maintaining surgically induced remission in people with CD who were in postsurgical remission. Participants had to have received maintenance treatment for at least three months. We excluded studies assessing enteral diet, diet manipulation, herbal medicine, and nutritional supplementation.
DATA COLLECTION AND ANALYSIS
Two review authors independently selected relevant studies, extracted data, and assessed the risk of bias. Any disagreements were resolved by discussion or by arbitration of a third review author when necessary. We conducted a network meta-analysis (NMA) using a Bayesian approach through Markov Chain Monte Carlo (MCMC) simulation. For the pairwise comparisons carried out in Review Manager 5, we calculated risk ratios (RR) with their corresponding 95% confidence intervals (95% CI). For the NMA, we presented hazard ratios (HR) with corresponding 95% credible intervals (95% CrI) and reported ranking probabilities for each intervention. For the NMA, we focused on three main outcomes: clinical relapse, endoscopic relapse, and withdrawals due to adverse events. Data were insufficient to assess time to relapse and histologic relapse. Adverse events and serious adverse events were not sufficiently or objectively reported to permit an NMA. We used CINeMA (Confidence in Network Meta-Analysis) methods to evaluate our confidence in the findings within networks, and GRADE for entire networks.
MAIN RESULTS
We included 35 RCTs (3249 participants) in the review. The average age of study participants ranged between 33.6 and 38.8 years. Risk of bias was high in 18 studies, low in four studies, and unclear in 13 studies. Of the 35 included RCTs, 26 studies (2581 participants; 9 interventions) were considered eligible for inclusion in the NMA. The interventions studied included 5-aminosalicylic acid (5-ASA), adalimumab, antibiotics, budesonide, infliximab, probiotics, purine analogues, sulfasalazine, and a combination of sulfasalazine and prednisolone. This resulted in 30 direct contrasts, which informed 102 mixed-treatment contrasts.The evidence for the clinical relapse network (21 studies; 2245 participants) and endoscopic relapse (12 studies; 1128 participants) were of low certainty while the evidence for withdrawal due to adverse events (15 studies; 1498 participants) was of very low certainty. This assessment was due to high risk of bias in most of the studies, inconsistency, and imprecision across networks. We mainly judged individual contrasts as of low or very low certainty, except 5-ASA versus placebo, the evidence for which was judged as of moderate certainty.We ranked the treatments based on effectiveness and the certainty of the evidence. For clinical relapse, the five most highly ranked treatments were adalimumab, infliximab, budesonide, 5-ASA, and purine analogues. We found some evidence that adalimumab (HR 0.11, 95% Crl 0.02 to 0.33; low-certainty evidence) and 5-ASA may reduce the probability of clinical relapse compared to placebo (HR 0.69, 95% Crl 0.53 to 0.87; moderate-certainty evidence). However, budesonide may not be effective in preventing clinical relapse (HR 0.66, 95% CrI 0.27 to 1.34; low-certainty evidence). We are less confident about the effectiveness of infliximab (HR 0.36, 95% CrI 0.02 to 1.74; very low-certainty evidence) and purine analogues (HR 0.75, 95% CrI 0.55 to 1.00; low-certainty evidence). It was unclear whether the other interventions reduced the probability of a clinical relapse, as the certainty of the evidence was very low.Due to high risk of bias and limited data across the network, we are uncertain about the effectiveness of interventions for preventing endoscopic relapse. Whilst there might be some evidence of prevention of endoscopic relapse with adalimumab (HR 0.10, 95% CrI 0.01 to 0.32; low-certainty evidence), no other intervention studied appeared to be effective.Due to high risk of bias and limited data across the network, we are uncertain about the effectiveness of interventions for preventing withdrawal due to adverse events. Withdrawal due to adverse events appeared to be least likely with sulfasalazine (HR 1.96, 95% Crl 0.00 to 8.90; very low-certainty evidence) and most likely with antibiotics (HR 53.92, 95% Crl 0.43 to 259.80; very low-certainty evidence). When considering the network as a whole, two adverse events leading to study withdrawal (i.e. pancreatitis and leukopenia) occurred in more than 1% of participants treated with an intervention. Pancreatitis occurred in 2.8% (11/399) of purine analogue participants compared to 0.17% (2/1210) of all other groups studied. Leukopenia occurred in 2.5% (10/399) of purine analogue participants compared to 0.08% (1/1210) of all other groups studied.
AUTHORS' CONCLUSIONS
Due to low-certainty evidence in the networks, we are unable to draw conclusions on which treatment is most effective for preventing clinical relapse and endoscopic relapse. Evidence on the safety of the interventions was inconclusive, however cases of pancreatitis and leukopenia from purine analogues were evident in the studies. Larger trials are needed to further understand the effect of the interventions on endoscopic relapse.

Meta-Analysis
BACKGROUND AND AIMS
Sexual functions are sometimes adversely affected by the therapeutic drugs delivered for treating IBD. Much attention has been focused on pregnancy/sexual issues in women. Relatively less attention has been poured in to address this issue in men. This systematic review assesses the drugs having potential detrimental effects on fertility in men.
METHODS
Three databases were searched by two researchers independently for potentially relevant publications between 1964 to 2015 and 249 papers were retrieved. Studies that dealt with sexual problems after IBD drugs administration were included in the purview of this review.
RESULTS
Fourteen studies with 327 human patients and 110 animals were analysed. Sulphasalazine treated patients had lower spermatozoa count, lower sperm motility and higher risk of oligospermia compared to mesalazine treated ones. Biologics seem to be safe to use while attempting to conceive however, proper clinical studies reporting male fertility problems in IBD patients are lacking. Azathioprine caused oligospermia but a meta-analytical approach was not possible due to heterogeneity in studies. Some animal studies showed methotrexate affects abnormal testis structure and spermatogenesis.
CONCLUSION
This study summarises the current literature and safety issues affecting fertility parameters in men and animals treated with IBD therapeutic drugs, which can further assist clinicians in better management of adult male IBD patients.

BACKGROUND
Crohn's disease (CD) is a chronic inflammatory disorder that can involve any part of the gastrointestinal tract. 5-Aminosalicylates (5-ASAs) are locally acting, anti-inflammatory compounds that reduce inflammation of the colonic mucosa with release profiles that vary among various commercially available formulations. This updated Cochrane review summarizes current evidence on the use of 5-ASA formulations for maintenance of surgically-induced remission in CD.
OBJECTIVES
To assess the efficacy and safety of 5-ASA agents for the maintenance of surgically-induced remission in CD.
SEARCH METHODS
We searched MEDLINE, Embase, CENTRAL, the Cochrane IBD Group Specialized Register from inception to 16 July 2018. We also searched references, conference abstracts, and trials registers.
SELECTION CRITERIA
Randomised controlled trials (RCTs) that included participants with CD in remission following surgery and compared 5-ASAs to no treatment, placebo or any other active intervention with duration of at least three months were considered for inclusion.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. The primary outcome was clinical relapse. Secondary outcomes included endoscopic recurrence, radiologic and surgical relapse, adverse events, serious adverse events and withdrawal due to adverse events.
MAIN RESULTS
Fourteen RCTs (1867 participants) were included in the review. Participants (15 to 70 years) were recruited from gastroenterology hospitals and medical clinics in Europe and North America and followed up between 3 and 72 months. The risk of bias was assessed as 'low' in one study, 'unclear' in seven and as 'high' in six.At 12 months, 36% (20/55) of participants in the 5-ASA group experienced clinical relapse compared to 51% (28/55) in the no treatment control group (RR 0.71, 95% CI 0.46 to 1.10; low certainty evidence). Moderate certainty evidence suggests that 5-ASAs are more effective for preventing clinical relapse than placebo. During a follow-up period of 12 to 72 months, 36% (131/361) of 5-ASA participants relapsed compared to 43% (160/369) of placebo participants (RR 0.83, 95% CI 0.72 to 0.96; I² = 0%; moderate certainty evidence). At 12 months, 17% (17/101) of the 4 g/day mesalamine group relapsed compared to 26% (27/105) of the 2.4 g/day group (RR 0.65, 95% CI 0.38 to 1.13; moderate certainty evidence). There was no evidence of a difference in clinical relapse rates when 5-ASA compounds were compared to purine antimetabolites. At 24 months, 61% (103/170) of mesalamine participants relapsed compared to 67% (119/177) of azathioprine participants (RR 0.90, 95% CI 0.76 to 1.07; I² = 28%; low certainty evidence). During 24 months, 50% (9/18) of 5-ASA participants had clinical relapse compared to 13% (2/16) of adalimumab participants (RR 4.0, 95% CI 1.01 to 15.84; low certainty evidence). The effects of sulphasalazine compared to placebo on clinical relapse rate is uncertain. After 18 to 36 months, 66% (95/143) of participants treated with sulphasalazine relapsed compared to 71% (110/155) in the placebo group (RR 0.88, 95% CI 0.56 to 1.38; I² = 38%; low certainty evidence).The effect of 5-ASA drugs on safety was uncertain. During 24 months follow-up, 4% (2/55) of 5-ASA participants experienced adverse events compared to none (0/55) in the no treatment control group (RR 5.00, 95% CI 0.25 to 101.81; very low certainty evidence). An equal proportion of 5-ASA participants (10%; 23/241) and placebo (9%; 20/225) groups experienced an adverse event during a follow-up of 3 to 72 months (RR 1.07, 95% CI 0.60 to 1.91; I² = 0%; low certainty evidence). Adverse event rates were similar in the 5-ASA and purine analogues groups. However, serious adverse events and withdrawals due to adverse events were more common in participants who received purine analogues than 5-ASA. At 52 weeks to 24 months, 52% (107/207) of 5-ASA participants had an adverse event compared to 47% (102/218) of purine analogue participants (RR 1.11, 95% CI 0.97 to 1.27, I² = 0%; low certainty evidence). Four per cent (6/152) of 5-ASA participants had a serious adverse event compared to 17% (27/159) of purine analogue participants (RR 0.30, 95% CI 0.11 to 0.80; very low certainty evidence). Eight per cent (17/207) of 5-ASA participants withdrew due to an adverse event compared to 19% (42/218) of purine analogue participants (RR 0.48, 95% CI 0.28 to 0.83; low certainty evidence). Adverse event rates were similar in high and low dose mesalamine participants. After 12 months, 2% (2/101) of 4 g/day mesalamine participants had an adverse event compared to 2% (2/105) of 2.4 g/day participants (RR 1.04, 95% CI 0.15 to 7.24; low certainty evidence). The proportion of participants who experienced adverse events over a 24 month follow-up in the mesalamine group was 78% (14/18) compared to 69% (11/16) of adalimumab participants (RR 1.13, 95% CI 0.75 to 1.71; very low certainty evidence). None (0/32) of the sulphasalazine participants had an adverse event at 18 months follow-up compared to 3% (1/34) of the placebo group (RR 0.35, 95% CI 0.01 to 8.38; very low certainty evidence). Commonly reported adverse events in the included studies were diarrhoea, nausea, increased liver function tests, pancreatitis, and abdominal pain.
AUTHORS' CONCLUSIONS
5-ASA preparations are superior to placebo for the maintenance of surgically-induced clinical remission in patients with CD (moderate certainty). The number needed to treat to prevent one relapse was 13 patients. The evidence for endoscopic remission is uncertain. The sulphasalazine class of 5-ASA agents failed to demonstrate superiority against placebo, 5-ASAs failed to demonstrate superiority compared to no treatment (very low and low certainty). The efficacy of two different doses of the same 5-ASA and the efficacy of 5-ASA compared to purine antimetabolites (azathioprine or 6-mercaptopurine) in maintaining surgically-induced remission of CD remains unclear. However, purine analogues lead to more serious adverse events and discontinuation due to adverse events. There is a low certainty that 5-ASA is inferior for maintaining surgically-induced remission of CD compared to biologics (anti TNF-ɑ). 5-ASA formulations appear to be safe with no difference in the occurrence of adverse events or withdrawal when compared with placebo, no treatment or biologics.

Etanercept (ETN) has been widely applied in the treatment of ankylosing spondylitis (AS). As the use of ETN has increased, associated adverse effects have been reported frequently. Previous meta-analyses have focused on comparing the differences in clinical outcomes between ETN and placebo (PBO). The present meta-analysis evaluated randomised controlled trials (RCTs) to compare the effects of ETN and a PBO or sulfasalazine (SSZ) in patients with AS. The study population characteristics and the main results, including the Assessment in AS 20% response (ASAS 20), the Bath AS Disease Activity Index (BASDAI) and the Bath AS Functional Index (BASFI), were extracted. The pooled odds ratios (ORs) or weighted mean differences (MDs) were calculated using a fixed or random effects model. Fifteen randomised controlled trials (RCTs) involving 2,194 subjects were included. Compared with a PBO, ETN significantly improved the ASAS 20 [P<0.00001; OR, 8.25; 95% confidence interval (CI), 5.92-11.50], BASDAI (P<0.00001; MD, -18.81; 95% CI, -24.47 to -13.15) and BASFI (P<0.00001; standard MD, -0.68; 95% CI, -0.85 to -0.50). In comparison with SSZ, ETN significantly decreased the BASDAI (P<0.00001; MD, -2.40; 95% CI, -2.89 to -1.90) and C-reactive protein (CRP) levels (P<0.0001; MD, -8.01; 95% CI, -11.73 to -4.29). The most common adverse effect of ETN was an injection site reaction. This meta-analysis shows that ETN monotherapy is effective in improving physical function and reducing disease activity in patients with AS. Compared with SSZ, ETN markedly decreased the BASDAI and CRP levels. However, the efficacy of ETN in treating AS requires further evaluation by more RCTs in a larger population of patients prior to recommending ETN as a substitute for synthetic disease-modifying antirheumatic drug (DMARD) monotherapy, or combinations of synthetic DMARDs.
