ABSTRACT

INTRODUCTION: Several randomized controlled trials (RCTs) have examined mineralocorticoid receptor antagonists (MRAs) in heart failure (HF) with reduced ejection fraction (HFrEF). This systematic review and network meta-analysis (NMA) evaluated the comparative efficacy and safety of MRAs in HFrEF. MATERIALS AND METHODS: MEDLINE(Pubmed), Scopus, Cochrane and ClinicalTrials.gov were searched until April 8, 2024 for RCTs examining the efficacy and/or safety of MRAs in HFrEF. Double-independent study selection, extraction and quality assessment were performed. Random-effects frequentist NMA models were used. Evidence certainty was assessed via Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Totally, 32 RCTs (15685 patients) were analyzed. Eplerenone ranked above spironolactone in all-cause mortality (hazard ratio {HR}=0.78, 95% confidence interval {CI} [0.66,0.91], GRADE:"Moderate"), cardiovascular death (HR=0.74, 95%CI [0.53, 1.04], GRADE:"Low") and in all safety outcomes. Spironolactone was superior to eplerenone in the composite of cardiovascular death or hospitalization (HR=0.67, 95%CI [0.50,0.89], GRADE:"Moderate"), HF hospitalization (HR=0.61, 95%CI [0.43,0.86], GRADE:"Moderate"), all-cause hospitalization (HR=0.51, 95%CI [0.26,0.98], GRADE:"Moderate") and cardiovascular hospitalization (HR=0.56, 95%CI [0.37,0.84], GRADE:"Moderate"). Canrenone ranked first in all-cause mortality, the composite outcome and HF hospitalization. Finerenone ranked first in hyperkalemia (risk ratio [RR]=1.56, 95%CI [0.89,2.74], GRADE:"Moderate"), renal injury (RR=0.56, 95%CI [0.24,1.29]), any adverse event (RR=0.84, 95%CI [0.75,0.94], GRADE:"Moderate"), treatment discontinuation (RR=0.89, 95%CI [0.64,1.23]) and hypotension (RR=1.06, 95%CI [0.12,9.41]). CONCLUSIONS: MRAs are effective in HFrEF with certain safety disparities. Spironolactone and eplerenone exhibited similar efficacy, however, eplerenone demonstrated superior safety. Finerenone was the safest MRA, while canrenone exhibited considerable efficacy, nonetheless, evidence for these MRAs were scarce.

ABSTRACT

BACKGROUND: Brugada Syndrome (BrS) is a life-threatening cardiac arrhythmia disorder associated with an increased risk ventricular arrhythmias (VAs) and sudden cardiac death (SCD). Current management primarily relies on implantable cardioverter-defibrillators (ICDs), but patients may experience ICD shocks. Catheter ablation (CA) has emerged as a potential intervention to target the arrhythmogenic substrate. This systematic review aims to evaluate the safety and efficacy of catheter ablation in BrS patients. METHODS AND RESULTS: Studies with BrS patients undergoing catheter ablation for VAs were included. 14 studies that involved a total population of 709 BrS patients, with catheter ablation performed in 528 of them, were included. Catheter ablation resulted in non-inducibility of VAs in 91% (95% CI: 83-99, I2 = 76%) and resolution of Type 1 ECG Brugada pattern in 88% (95% CI: 81-96.2, I2 = 91%) of the patients. After a mean follow-up of 30.7 months, 87% (95% CI: 80-94, I2 = 82%) of patients remained free from VAs. The incidence of VAs during follow-up was significantly lower in the ablation cohort in comparison to the group receiving only ICD therapy (OR = 0.03, 95% CI: 0.01-0.12, I2 = 0%). CONCLUSION: Catheter ablation shows potential as a therapeutic approach to reduce VAs and improve outcomes in BrS patients. While further research with long follow-up period is required to confirm these findings, it represents a valuable tool as an add-on intervention to ICD implantation in BrS patients with high burden of VAs.Protocol registration: CRD42024506439.

ABSTRACT

Randomized controlled trials represent the cornerstone for the regulatory approval of drugs and evidence-based medicine and policy. Compared with observational studies random assignment of participants to each study arm guarantees an equal distribution of potential confounders thus achieving impartiality in the evaluation of between group differences and allowing for causal inferences to be drawn. These complex and costly medical experiments are tightly regulated and require substantial planning with great attention to several methodological aspects ranging from allocation concealment and blinding to sample size estimation, statistical analysis, and handling of protocol deviations. This brief guide offers useful insights into the design, conduct, and interpretation of clinical trial findings for beginners.

ABSTRACT

OBJECTIVES: To conduct a methodological overview of reviews to evaluate the reporting completeness and transparency of systematic reviews (SRs) of prognostic prediction models (PPMs) for COVID-19. STUDY DESIGN AND SETTING: MEDLINE, Scopus, Cochrane Database of Systematic Reviews, and Epistemonikos (epistemonikos.org) were searched for SRs of PPMs for COVID-19 until December 31, 2022. The risk of bias in systematic reviews tool was used to assess the risk of bias. The protocol for this overview was uploaded in the Open Science Framework (https://osf.io/7y94c). RESULTS: Ten SRs were retrieved; none of them synthesized the results in a meta-analysis. For most of the studies, there was absence of a predefined protocol and missing information on study selection, data collection process, and reporting of primary studies and models included, while only one SR had its data publicly available. In addition, for the majority of the SRs, the overall risk of bias was judged as being high. The overall corrected covered area was 6.3% showing a small amount of overlapping among the SRs. CONCLUSION: The reporting completeness and transparency of SRs of PPMs for COVID-19 was poor. Guidance is urgently required, with increased awareness and education of minimum reporting standards and quality criteria. Specific focus is needed in predefined protocol, information on study selection and data collection process, and in the reporting of findings to improve the quality of SRs of PPMs for COVID-19.

ABSTRACT

PURPOSE: This study aimed to apply different methods of diagnostic test accuracy network meta-analysis (DTA-NMA) for studies reporting results of five imaging tests for the diagnosis of suspected pulmonary embolism (PE): pulmonary angiography (PA), computed tomography angiography (CTPA), magnetic resonance angiography (MRA), planar ventilation/perfusion (V/Q) scintigraphy and single-photon emission computed tomography ventilation/perfusion (SPECT V/Q). METHODS: We searched four databases (MEDLINE [via PubMed], Cochrane CENTRAL, Scopus, and Epistemonikos) from inception until June 2, 2022 to identify systematic reviews (SRs) describing diagnostic accuracy of PA, CTPA, MRA, V/Q scan and SPECT V/Q for suspected PE. Study-level data were extracted and pooled using a hierarchical summary receiver operating characteristic (HSROC) meta-regression approach and two DTA-NMA models to compare accuracy estimates of different imaging tests. Risk of bias was assessed using the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies-2) tool and certainty of evidence using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework. RESULTS: We identified 13 SRs, synthesizing data from 33 primary studies and for four imaging tests (PA, CTPA, MRA and V/Q scan). The HSROC meta-regression model using PA as the reference standard showed that MRA had the best overall diagnostic performance with sensitivity of 0.93 (95% confidence interval [CI]: 0.76, 1.00) and specificity of 0.94 (95% CI: 0.84, 0.99). However, DTA-NMA models indicated that V/Q scan had the highest sensitivity, while CTPA was most specific. CONCLUSION: Selecting a different DTA-NMA method to assess multiple diagnostic tests can affect estimates of diagnostic accuracy. There is no established method, but the choice depends on the data and familiarity with Bayesian statistics.

ABSTRACT

Histologic markers of increased risk for hepatocellular carcinoma can provide useful information for the management of patients with chronic hepatitis B. The expression of epithelial cell adhesion molecule (EpCAM, a marker of hepatic progenitor cells), p21 (a marker of hepatocyte senescence), glutamine synthetase (a marker of perivenular hepatocytes) and CD34 (a marker of sinusoidal capillarization) were assessed by immunohistochemistry in 52 liver biopsy specimens from patients with advanced stage chronic hepatitis B. Nineteen patients developed hepatocellular carcinoma during a follow-up period of 133 months. The findings were compared with those of 18 liver biopsy specimens from patients with early-stage chronic hepatitis B and 6 liver biopsy specimens without significant pathologic findings. EpCAM expression in hepatocytes was significantly increased in specimens with advanced stage, as compared with all other specimens. EpCAM positivity in over 30 % of hepatocytes was only seen in 3 specimens from patients who subsequently developed hepatocellular carcinoma. The expression of p21, glutamine synthetase and CD34 was not associated with hepatocellular carcinoma development. Nevertheless, glutamine synthetase immunostains highlighted zonality abnormalities that were useful in chronic hepatitis B staging. In conclusion, extensive immunopositivity of hepatocytes for EpCAM in chronic hepatitis B may represent a marker of increased hepatocellular carcinoma risk. Glutamine synthetase immunostaining represents a useful adjunct in determining the stage of chronic hepatitis B in diagnostic practice.

ABSTRACT

This systematic review and meta-analysis aims to evaluate the predictive value of total atrial conduction time (TACT) assessed by tissue Doppler echocardiography (PA-TDI) in atrial fibrillation (AF) recurrence in patients following a rhythm-control strategy. A systematic approach following Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines was applied in electronic databases (Pubmed, Cochrane Library, and Web of Science), supplemented by scanning through studies' references. TACT was compared using a random-effects model and presented as a difference in means (MD). The primary endpoint was AF recurrence. Seven publications were included in this systematic review. The mean age of the patients ranged from 55 years to 72 years. Prolonged TACT was associated with AF recurrence [MD, 23.12 msec; 95% confidence interval (CI), 11.54-34.71; I2 = 95%]. Subgroup analysis showed that prolonged TACT was strongly associated with AF recurrence in persistent AF cohorts undergoing electrical cardioversion (MD, 26.56; 95% CI, 15.51-37.6; I2 = 86%), while in patients with paroxysmal AF (PAF) undergoing catheter ablation, the results were not statistically significant (MD, 11.48; 95% CI, -1.19 to 24.14; I2 = 90%). The summary area under the curve (sAUC) using a random-effects model was 0.89 (95% CI, 0.80-0.99). TACT is a valuable echocardiographic parameter that can predict AF recurrence in patients following a rhythm-control strategy.

ABSTRACT

BACKGROUND AND AIMS: Αvaialble evidence regarding the effectiveness of intragastric injection of botulinum toxin in reducing anthropometric indices of subjects with obesity is conflicting. We evaluated the existing evidence and perform a meta-analysis to assess the efficacy of intragastric botulinum toxin in treating obesity. METHODS: We identified published systematic reviews evaluating the efficacy of intragastric injection of botulinum toxin in patients with overweight or obesity and additionally performed a systematic literature search to retrieve randomized controlled trials on this topic. A random-effects meta-analysis was performed to synthesize the existing studies. RESULTS: A total of four systematic reviews were included in our overview of systematic reviews and six randomized controlled trials were included in our meta-analysis. Compared to placebo, intragastric injection of botulinum toxin was ineffective in reducing body weight and body mass index after the application of the Knapp-Hartung adjustment (MD = -2.41 kg, 95%CI = -5.21 to 0.38, I2 =59% and MD = -1.43 kg/m2, 95%CI = -3.04 to 0.18, I2 =62%, respectively). Moreover, treatment with intragastric injection with botulinum toxin was not superior to placebo in decreasing waist and hip circumference. CONCLUSIONS: Based on the available evidence, intragastric injection with botulinum toxin is an ineffective procedure in reducing body weight and body mass index when the Knapp-Hartung method was applied.

ABSTRACT

OBJECTIVE: Halting and reversing glaucoma therapy-related ocular surface disease (GTR-OSD) will improve the success of long-term medical therapy, impacting millions of patients worldwide. METHODS: A single-centre, masked, prospective, placebo-controlled, crossover trial of 41 well-controlled open-angle glaucoma subjects with moderate to severe GTR-OSD on preserved latanoprost and dorzolamide/timolol fixed combination (DTFC) therapy was conducted. Subjects were randomized to preservative-free (PF) tafluprost and DTFC with either placebo or cyclosporine 0.1% drops for 6 months and were then crossed over to the opposite therapy. Oxford score of ocular staining was the primary outcome; osmolarity, matrix-metalloproteinase-9 (MMP-9) testing, tear film break-up time (TFBUT), meibomian gland dysfunction (MGD), punctum evaluation, adverse events and diurnal intraocular pressure (IOP) comprised secondary outcomes. RESULTS: GTR-OSD findings improved with PF therapy. At 6 months the triple PF with placebo group showed improvement compared to baseline in mean Oxford score (mean difference [MD]:-3.76; 95% confidence interval [CI]:-4.74 to -2.77; p < 0.001), osmolarity (MD:-21.93; 95%CI:-27.61 to -16.24 mOsm/l; p < 0.001), punctum stenosis (p = 0.008) and conjunctival hyperaemia (p < 0.001). Similar improvements occurred in the cyclosporine enhanced period, which also provided greater improvement in MMP-9 positivity (24 vs 66%; p < 0.001) and TFBUT (p = 0.022). The cyclosporine group was superior vs placebo in mean Oxford score (MD:-0.78; 95%CI:-1.40 to -0.15); p < 0.001), itchiness and objective adverse events (p = 0.034). Cyclosporine elicited more stinging vs placebo (63 vs 24%; p < 0.001). Both PF regimens reduced mean diurnal IOP more than preserved therapy (14.7 vs 15.9 mmHg; p < 0.001). CONCLUSIONS: Changing from preserved to PF glaucoma medications improves ocular surface health and IOP control. Topical cyclosporine 0.1% further reverses GTR-OSD.

ABSTRACT

BACKGROUND: We performed a network meta-analysis of randomized controlled trials comparing non-vitamin K antagonist oral anticoagulant (NOAC)-based versus vitamin K antagonists (VKA)-based regimens in patients with atrial fibrillation (AF) and acute coronary syndromes or PCI, aiming to examine the precise impact of recently established antithrombotic strategies on major bleeding as primary end-point and other safety and efficacy as secondary end-points. METHODS: A literature search was conducted for randomized controlled trials. Our search took place in three major databases. The primary endpoint of our study was bleeding. To combine direct and indirect evidence across trials, a frequentist network meta-analysis with a random-effects model was used. RESULTS: Five studies were found eligible for the meta-analysis enrolling a total of 11,542 patients. Five studies (N = 4903 patients) contributed to the network. Compared to the triple antithrombotic therapy (TAT)-based VKA, only the dual antithrombotic therapy (DAT) based NOAC reduced the bleeding (RR 0.57, 95%CI 0.40-0.82). There was no statistically significant difference between DAT-based VKA (RR = 0.66, 95%CI = 0.40-1.09) or TAT-based NOAC (RR = 0.80, 95%CI = 0.43-1.49). DAT-based NOAC ranked best (P-score = 0.91), followed by DAT-based VKA (P-score = 0.67), TAT-based NOAC (P-score = 0.40), and TAT-based VKA (P-score = 0.03). CONCLUSION: The network meta-analysis of four antithrombotic strategies, demonstrated that in patients with AF undergoing PCI the combination of DAT-based NOAC is associated with a significantly lower risk of major bleeding events. This strategy does not seem to be less effective in terms of prevention of ischemic events compared to the other regimens.

ABSTRACT

AIM: We conducted a systematic review and meta-analysis of randomized and observational studies with a control group to evaluate the effectiveness and safety of a time to isolation (TTI)-based strategy of cryoballoon ablation (CBA) in the treatment of atrial fibrillation (AF). METHODS: Three electronic databases (MEDLINE, Cochrane Central Register of Controlled Trials, and Embase) without language restrictions were searched. The intervention assessed was a TTI-based strategy of CBA in the treatment of AF. TTI was defined as the time from the start of freezing to the last recorded pulmonary veins' potential. The comparison of interest was intended conventional protocol of CBA. The primary endpoint was freedom from atrial arrhythmia. RESULTS: Nine studies were deemed eligible (N = 2289 patients). Eight studies reported freedom from atrial arrhythmia and pooled results showed a marginally similar success rate between the two protocols (odds ratio [OR]: 1.24; 95% confidence interval [CI]: 0.98-1.56). A prespecified subgroup analysis verified that a high dose TTI strategy (with >120 s duration of cryotherapy post-TTI) compared to the conventional protocol could significantly increase the patients without atrial arrhythmia during follow-up (OR: 1.39; 95% CI: 1.05-1.83). TTI strategy could also significantly decrease total procedure time (SMD: -26.24 min; 95% CI: -36.90 to -15.57) and phrenic nerve palsy incidence (OR: 0.49; 95% CI: 0.29-0.84). CONCLUSION: Moderate confidence evidence suggests that an individualized CBA dosing strategy based on TTI and extended (>2 min post-TTI) duration of CBA is accompanied by fewer recurrences post-AF ablation.

ABSTRACT

The purpose of this study was to assess the utility of 2-D shear wave elastography (SWE) in assessing liver fibrosis in patients with chronic liver disease by comparing its performance with that of point shear wave elastography (pSWE) using liver histological staging as the reference standard. In this ethics committee-approved, single-institution prospective study, pSWE and 2-D SWE velocity measurements were obtained in 121 adult patients (age: 18-70 y, median: 45 y) immediately before a liver biopsy for chronic liver disease. Shear wave velocity (SWV) and Ishak scores were compared using the Kruskal-Wallis test, Spearman's correlation and receiver operating characteristic (ROC) curve analysis. Youden's index was used to determine the optimal cutoff point. There was no technical failure using pSWE and 2-D SWE. The mean difference for SWV between pSWE and 2-D SWE was 0.0223 (limits of agreement: -1.1009, 1.1145). Values for both pSWE and 2-D SWE were significantly correlated with fibrosis stage (Spearman's ρ = 0.606, p < 0.0001; ρ = 0.722, p < 0.001 respectively). The area under the ROC curve differentiating F ≥3 was 0.855 (95% confidence interval: 0.778-0.932) for pSWE and 0.884 (95% CI: 0.817-0.951) for 2-D SWE. The AUC for differentiating F ≥5 was 0.890 (95% CI: 0.826-0.954) for pSWE and 0.926 (95% CI: 0.88-0.973) for 2-D SWE. This study indicates that 2-D SWE provides feasible and accurate assessment of liver fibrosis, comparable to that provided by pSWE from two different manufacturers' machines.

ABSTRACT

Patients with haematological malignancies (HM) face high rates of intensive care unit (ICU) admission and mortality. High-flow nasal cannula oxygen (HFNCO) is increasingly used to support HM patients in ward settings, but there is limited evidence on the safety and efficacy of HFNCO in this group. We retrospectively reviewed all HM patients receiving ward-based HFNCO, supervised by a critical care outreach service (CCOS), from January 2014 to January 2019. We included 130 consecutive patients. Forty-three (33.1%) were weaned off HFNCO without ICU admission. Eighty-seven (66.9%) were admitted to ICU, 20 (23.3%) required non-invasive and 34 (39.5%) invasive mechanical ventilation. ICU and hospital mortality were 42% and 55% respectively. Initial FiO2 < 0.4 (OR 0.27, 95% CI 0.09-0.81, p = 0.019) and HFNCO use on the ward > 1 day (OR 0.16, 95% CI 0.04, 0.59, p = 0.006) were associated with reduced likelihood for ICU admission. Invasive ventilation was associated with reduced survival (OR 0.27, 95%CI 0.1-0.7, p = 0.007). No significant adverse events were reported. HM patients receiving ward-based HFNCO have higher rates of ICU admission, but comparable hospital mortality to those requiring CCOS review without respiratory support. Results should be interpreted cautiously, as the model proposed depends on the existence of CCOS.

ABSTRACT

PURPOSE: The objective of the present systematic review was to compare the effectiveness and safety of class Ic agents for cardioversion of paroxysmal atrial fibrillation (AF), in patients with and without structural heart disease (SHD). METHODS: We focused on RCTs enrolling at least 50 adult patients with electrocardiogram-documented paroxysmal AF that compared either two pharmacological class Ic cardioversion agents (flecainide, propafenone), regardless of study design (parallel or crossover). We searched MEDLINE and the Cochrane Central Register of Controlled Trials. Initial search was performed from inception to 15 July 2021 with no language restrictions. RESULTS: Intravenous flecainide is the most effective option for pharmacologic cardioversion of AF since only 2 patients need to be treated in order to cardiovert one more within 4 h. Most importantly, class Ic agents appear to be safe in the context of pharmacologic cardioversion of AF irrespective of the presence of SHD, pointing towards a possible reappraisal of the role in this setting. CONCLUSION: We suggest that class Ic agents (with flecainide appearing to be more effective) should be used for pharmacologic cardioversion in stable AF patients presenting in emergency department with unknown medical history, after excluding severe cardiac disease through a bedside examination.

ABSTRACT

OBJECTIVES: To (a) identify methodological and application papers reporting a model developed specifically for diagnostic test accuracy network meta-analysis (DTA-NMA) or a hierarchical meta-regression method for comparing at least three index tests; (b) review and summarize the characteristics of the methods and the application papers; and (c) compare DTA-NMA and hierarchical meta-regression methods empirically. STUDY DESIGN AND SETTING: We performed a scoping review and searched major databases until March 3rd, 2021. We assessed the characteristics of the identified methods, conducted a descriptive analysis of characteristics of the application articles, and applied the DTA-NMA and meta-regression methods to the available data. RESULTS: We included 49 articles (plus one companion report), of which nine were methodological (describing 11 DTA-NMA methods) and 40 were application papers (data available for 32 DTA-NMAs). Our results showed a steep increase in recent years in DTA-NMA publications. DTA-NMA models may lead to different results. Although sensitivity estimates were comparable between meta-regression and DTA-NMA models, specificity estimates were higher in meta-regression. CONCLUSION: The choice of a DTA-NMA model will depend on the available data, including the use of different thresholds for test positivity, different study designs, and software familiarity. Selection between the methods may impact on the NMA results, especially for specificity.

ABSTRACT

OBJECTIVE: Journal abstracts are crucial for the identification and initial assessment of content of studies. We evaluated whether authors in the field of cardiovascular diseases (CVDs) reported Diagnostic Test Accuracy Systematic Reviews (DTA SRs) abstracts adequately, as defined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-DTA guidelines. METHODS: SRs of DTA studies in CVDs published in general and specialized medical journals were identified in a MEDLINE search between 2010-2020. Adherence to 12 PRISMA-DTA for abstracts items was assessed independently by two reviewers and compared by journal's type. Moreover, the association of reporting completeness with different characteristics was investigated. RESULTS: We included 72 abstracts. Studies published in general medical journals had higher mean reporting score than those in specialized journals (6.2 vs 5.3 out of 12 items; mean difference: 0.88; 95% confidence interval: 0.21, 1.55). PRISMA-DTA adherence was higher in journals that adopted this guideline and in articles with structured abstracts. However, number of participants analysed, funding and registration were the least-reported items in the identified abstracts. CONCLUSION: The reporting of abstracts of DTA reports in CVDs is suboptimal according to PRISMA-DTA guidelines. Abstract reporting could be improved with the use of higher word count limits and the adoption of PRISMA-DTA guidelines especially in specialized journals.

ABSTRACT

PURPOSE: We sought to indirectly compare and rank antiarrhythmic agents focusing exclusively on adults with paroxysmal atrial fibrillation in order to identify the most effective for pharmacologic cardioversion over different time settings (4 h as primary, and 12, 24 h as secondary outcomes). METHODS: We searched several databases from inception to March 2020 without language restrictions, ClinicalTrials.gov, references of reviews, and meeting abstract material. We included randomized controlled trials of patients with AF lasting ≤7 days comparing either two or more intravenous (i.v.) or oral (p.o.) pharmacologic cardioversion agents or an agent against placebo. For each outcome, we performed network meta-analysis based on the frequentist approach. RESULTS: Forty-one trials (6013 patients) were included in our systematic review. Moderate confidence evidence suggests that i.v. vernakalant and flecainide have the highest conversion rate within 4 h, possibly allowing discharge from the emergency department and reducing hospital admissions. Intravenous and p.o. formulations of class IC antiarrhythmics (flecainide more so than propafenone) are superior regarding conversion rates within 12 h, while amiodarone efficacy is exhibited in a delayed fashion (within 24 h), especially if ranolazine is added. CONCLUSION: Our network meta-analysis identified with sufficient power and consistency the most effective antiarrhythmics for pharmacologic cardioversion over different time settings, with vernakalant and flecainide exhibiting a safer and more efficacious profile toward faster cardioversion.

ABSTRACT

OBJECTIVE: Many treatment modalities have been used to manage psoriasis; however, there is, to our knowledge, no pooled estimate for the effectiveness of oral vitamin D supplements in patients with psoriasis. Hence, the aim of the present study was to systematically review and meta-analyze the efficacy of oral vitamin D supplementation in lessening disease severity of patients with psoriasis. METHODS: A systematic literature review was performed on the electronic databases PubMed, Embase, and Cochrane Central and the gray literature for retrieving randomized controlled trials comparing oral vitamin D supplementation with placebo. The primary outcome was the change of Psoriasis Area and Severity Index (PASI) score. We used the random effects model for synthesizing the evidence. RESULTS: Of the total 5018 search results, 4 studies were included in the qualitative and 3 studies in quantitative analysis. Vitamin D supplementation was effective in ameliorating the PASI score after 6 mo of intervention (mean difference [MD] = -0.92, 95% confidence interval [CI] = -1.72 to -0.11). However, after the Hartung-Knapp adjustment, the results became non-significant (MD = -0.92, 95% CI = -2.21 to 0.38). CONCLUSIONS: A favorable effect of oral vitamin D supplementation in patients with psoriasis could not be verified. More randomized controlled trials with larger sample sizes are needed to produce robust results.
