Meta-Analysis
To assess the efficacy and safety of sodium-glucose co-transporter 2 (SGLT2) inhibitors plus a dipeptidyl peptidase-4 (DPP-4) inhibitor in patients with type 2 diabetes mellitus (T2DM), we performed a systematic review and meta-analysis of 14 randomized controlled trials (RCTs) involving 4828 patients. Compared with a DPP-4 inhibitor, SGLT2 inhibitor/DPP-4 inhibitor combination therapy was significantly associated with a decrease in glycaemic control (HbA1c, -0.71%; fasting plasma glucose [FPG], -25.62 mg/dL; postprandial plasma glucose, -44.00 mg/dL), body weight (-2.05 kg) and systolic blood pressure (-5.90 mm Hg), but an increase in total cholesterol (TC) of 3.24%, high-density lipoprotein of 6.15% and low-density lipoprotein of 2.55%. Adding a DPP-4 inhibitor to an SGLT2 inhibitor could reduce HbA1c by -0.31%, FPG by -8.94 mg/dL, TC by -1.48% and triglycerides by -3.25%. Interestingly, low doses of an SGLT2 inhibitor in the combination has similar or even better efficacy in some aspects than high doses. Similar adverse events were observed for the combination therapy, with the exception of genital infection vs DPP-4 inhibitor (risk ratio [RR], 5.31) and consistent genital infection vs an SGLT2 inhibitor (RR, 0.61). Further studies are warranted to confirm these results.

Meta-Analysis Review
BACKGROUND
The optimal treatment of superficial thrombophlebitis (ST) of the legs remains poorly defined. While improving or relieving the local painful symptoms, treatment should aim at preventing venous thromboembolism (VTE), which might complicate the natural history of ST. This is the third update of a review first published in 2007.
OBJECTIVES
To assess the efficacy and safety of topical, medical, and surgical treatments for ST of the leg in improving local symptoms and decreasing thromboembolic complications.
SEARCH METHODS
For this update, the Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register (March 2017), CENTRAL (2017, Issue 2), and trials registries (March 2017). We handsearched the reference lists of relevant papers and conference proceedings.
SELECTION CRITERIA
Randomised controlled trials (RCTs) evaluating topical, medical, and surgical treatments for ST of the legs that included people with a clinical diagnosis of ST of the legs or objective diagnosis of a thrombus in a superficial vein.
DATA COLLECTION AND ANALYSIS
Two authors assessed the trials for inclusion in the review, extracted the data, and assessed the quality of the studies. Data were independently extracted from the included studies and any disagreements resolved by consensus. We assessed the quality of the evidence using the GRADE approach.
MAIN RESULTS
We identified three additional trials (613 participants), therefore this update considered 33 studies involving 7296 people with ST of the legs. Treatment included fondaparinux; rivaroxaban; low molecular weight heparin (LMWH); unfractionated heparin (UFH); non-steroidal anti-inflammatory drugs (NSAIDs); compression stockings; and topical, intramuscular, or intravenous treatment to surgical interventions such as thrombectomy or ligation. Only a minority of trials compared treatment with placebo rather than an alternative treatment and many studies were small and of poor quality. Pooling of the data was possible for few outcomes, and none were part of a placebo-controlled trial. In one large, placebo-controlled RCT of 3002 participants, subcutaneous fondaparinux was associated with a significant reduction in symptomatic VTE (risk ratio (RR) 0.15, 95% confidence interval (CI) 0.04 to 0.50; moderate-quality evidence), ST extension (RR 0.08, 95% CI 0.03 to 0.22; moderate-quality evidence), and ST recurrence (RR 0.21, 95% CI 0.08 to 0.54; moderate-quality evidence) relative to placebo. Major bleeding was infrequent in both groups with very wide CIs around risk estimate (RR 0.99, 95% CI 0.06 to 15.86; moderate-quality evidence). In one RCT on 472 high-risk participants with ST, fondaparinux was associated with a non-significant reduction of symptomatic VTE compared to rivaroxaban 10 mg (RR 0.33, 95% CI 0.03 to 3.18; low-quality evidence). There were no major bleeding events in either group (low-quality evidence). In another placebo-controlled trial, both prophylactic and therapeutic doses of LMWH (prophylactic: RR 0.44, 95% CI 0.26 to 0.74; therapeutic: RR 0.46, 95% CI 0.27 to 0.77) and NSAIDs (RR 0.46, 95% CI 0.27 to 0.78) reduced the extension (low-quality evidence) and recurrence of ST (low-quality evidence) in comparison to placebo, with no significant effects on symptomatic VTE (low-quality evidence) or major bleeding (low-quality evidence). Overall, topical treatments improved local symptoms compared with placebo, but no data were provided on the effects on VTE and ST extension. Surgical treatment combined with elastic stockings was associated with a lower VTE rate and ST progression compared with elastic stockings alone. However, the majority of studies that compared different oral treatments, topical treatments, or surgery did not report VTE, ST progression, adverse events, or treatment adverse effects.
AUTHORS' CONCLUSIONS
Prophylactic dose fondaparinux given for 45 days appears to be a valid therapeutic option for ST of the legs for most people. The evidence on topical treatment or surgery is too limited and does not inform clinical practice about the effects of these treatments in terms of VTE. Further research is needed to assess the role of rivaroxaban and other direct oral factor-X or thrombin inhibitors, LMWH, and NSAIDs; the optimal doses and duration of treatment in people at various risk of recurrence; and whether a combination therapy may be more effective than single treatment. Adequately designed and conducted studies are required to clarify the role of topical and surgical treatments.

Proteases and protease inhibitors (P/PIs) are involved in many biological processes in human skin, yet often only specific families or related groups of P/PIs are investigated. Proteomics approaches, such as mass spectrometry, can define proteome signatures (including P/PIs) in tissues; however, they struggle to detect low-abundance proteins. To overcome these issues, we aimed to produce a comprehensive proteome of all P/PIs present in normal and diseased human skin, in vivo, by carrying out a modified systematic review using a list of P/PIs from MEROPS and combining this with key search terms in Web of Science. Resulting articles were manually reviewed against inclusion/exclusion criteria and a dataset constructed. This study identified 111 proteases and 77 protease inhibitors in human skin, comprising the serine, metallo-, cysteine and aspartic acid catalytic families of proteases. P/PIs showing no evidence of catalytic activity or protease inhibition, were designated non-peptidase homologs (NPH), and no reported protease inhibitory activity (NRPIA), respectively. MMP9 and TIMP1 were the most frequently published P/PIs and were reported in normal skin and most skin disease groups. Normal skin and diseased skin showed significant overlap with respect to P/PI profile; however, MMP23 was identified in several skin disease groups, but was absent in normal skin. The catalytic profile of P/PIs in wounds, scars and solar elastosis was distinct from normal skin, suggesting that a different group of P/PIs is responsible for disease progression. In conclusion, this study uses a novel approach to provide a comprehensive inventory of P/PIs in normal and diseased human skin reported in our database. The database may be used to determine either which P/PIs are present in specific diseases or which diseases individual P/PIs may influence.

Comparative Study Meta-Analysis
UNLABELLED
BACKGROUND AND OBJECTIVE: Systematic reviews and meta-analyses of direct oral anticoagulants (DOACs) for patients with chronic kidney disease (CKD) or dialysis patients are lacking. We aimed to compare the efficacy and safety of DOACs and warfarin in patients with CKD requiring anticoagulation therapy.
METHODS
We performed a systematic review and meta-analysis of six randomized controlled trials and 19 observational studies, with the inclusion criteria being a comparative study between DOACs and warfarin in patients with CKD or dialysis patients from database inception until August 2020. The efficacy outcomes were stroke, systemic embolism (SE), or venous thromboembolism (VTE), and the safety outcome was major bleeding.
RESULTS
Compared with warfarin, DOACs significantly reduced the risk of stroke/SE/VTE by 22% (hazard ratio [HR] = 0.78, 95% confidence interval [CI] 0.64-0.95) and major bleeding by 17% (HR = 0.83, 95% CI 0.71-0.97). On comparing factor Xa inhibitors and dabigatran with warfarin separately, factor Xa inhibitors significantly reduced the risk of stroke/SE/VTE (HR = 0.78, 95% CI 0.62-0.98) and major bleeding (HR = 0.76, 95% CI 0.64-0.91) overall in patients. Comparing each DOACs with warfarin separately, apixaban was associated with a significantly better risk reduction of stroke/SE/VTE (25% risk reduction) and major bleeding (35% risk reduction) than warfarin. Compared with warfarin, DOACs significantly reduced the risk of stroke, SE, or VTE by 19% (HR = 0.81, 95% CI 0.68-0.97) in patients with CKD stage 3 and significantly lowered the risk of major bleeding by 31% (HR = 0.69, 95% CI 0.56-0.85) in patients with CKD stages 4-5.
CONCLUSIONS
In pooled, analyzed randomized controlled trials and observational studies, DOACs were associated with better efficacy in early CKD, as well as similar efficacy and safety outcomes to warfarin in patients with CKD stages 4-5 or dialysis patients. The results of patients with CKD stages 4-5 and dialysis patients were from observational studies. Well-designed randomized controlled trials focused on DOAC use in patients with CKD and dialysis patients are needed. PROSPERO register number: CRD42020150599, 6 February, 2020.

Meta-Analysis Review
BACKGROUND
Chronic glomerulonephritis (CGN) is a relatively common primary glomerular disease. Huangkui capsule (HKC) combined with angiotensin receptor blocker (ARB) for CGN is frequently used in clinical practice, however, there is still lack of high-quality evidence-based evidence and network pharmacology to clarify the therapeutic efficacy and pharmacological mechanisms.
PURPOSE
Integrating evidence-based medicine and network pharmacology to explain the therapeutic efficacy and pharmacological mechanisms of ARB combined with HKC for CGN.
METHODS
Studies matching the topic were searched from PubMed, Web of Science, Embase database, the Cochrane Library, Chinese National Knowledge Infrastructure, CBM databases, the VIP medicine information system and the Wanfang database and screened according to inclusion and exclusion criteria. The data of the included studies were meta-analyzed by blood urea nitrogen (BUN), serum creatinine (SCR), 24-h urine protein (24hUP) and effective rate (ER). A meta-analysis of the data from the included studies was performed. Then, based on the network pharmacology, the chemical ingredients in HKC and their targets of action, disease targets, common targets and other relevant information were screened, and the key pathways were relevantly annotated based on bioinformatics technology to explore the potential mechanisms of HKC and ARB for CGN.
RESULTS
The results showed that SCR index (p < 0.05), 24hUP index (p < 0.001) in the group treated with HKC and ARB were significantly lower than those in the control group. BUN index in the group treated with HKC and VAL were significantly lower than those in the control group (p < 0.001). Effective rate index in the group treated with HKC and ARB was significantly higher than those in the control group (p < 0.001). There was no significant difference in BUN treated with IRB, LOS, and TEL (p = 0.181; p = 0.811; p = 0.067). Based on network pharmacology, the results were as follows: The PPI network indicated that STAT3, AKT1, MAPK1, TP53 and JUN were key target proteins. The results of KEGG analysis suggested that the pharmacological mechanisms were mainly associated with AGE-RAGE signaling pathway in diabetic complications.
CONCLUSION
The combination of ARB and HKC can achieve better therapeutic effects in the treatment of CGN, meanwhile, ARB and HKC have a significant improved effectiveness in the treatment of CGN compared with ARB or HKC alone. In addition, HKC and ARB synergistically treated CGN through a multi-pathway network.

Meta-Analysis Review
BACKGROUND
Deep vein thrombosis (DVT) is a condition in which a clot forms in the deep veins, most commonly of the leg. It occurs in approximately one in 1000 people. If left untreated, the clot can travel up to the lungs and cause a potentially life-threatening pulmonary embolism (PE). Previously, a DVT was treated with the anticoagulants heparin and vitamin K antagonists. However, two forms of direct oral anticoagulants (DOACs) have been developed: oral direct thrombin inhibitors (DTIs) and oral factor Xa inhibitors, which have characteristics that may be favourable compared to conventional treatment, including oral administration, a predictable effect, lack of frequent monitoring or dose adjustment and few known drug interactions. DOACs are now commonly being used for treating DVT: recent guidelines recommended DOACs over conventional anticoagulants for both DVT and PE treatment. This Cochrane Review was first published in 2015. It was the first systematic review to measure the effectiveness and safety of these drugs in the treatment of DVT. This is an update of the 2015 review. OBJECTIVES: To assess the effectiveness and safety of oral DTIs and oral factor Xa inhibitors versus conventional anticoagulants for the long-term treatment of DVT.
SEARCH METHODS
The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase and CINAHL databases and the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 1 March 2022.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) in which people with a DVT, confirmed by standard imaging techniques, were allocated to receive an oral DTI or an oral factor Xa inhibitor compared with conventional anticoagulation or compared with each other for the treatment of DVT. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were recurrent venous thromboembolism (VTE), recurrent DVT and PE. Secondary outcomes included all-cause mortality, major bleeding, post-thrombotic syndrome (PTS) and quality of life (QoL). We used GRADE to assess the certainty of evidence for each outcome.
MAIN RESULTS
We identified 10 new studies with 2950 participants for this update. In total, we included 21 RCTs involving 30,895 participants. Three studies investigated oral DTIs (two dabigatran and one ximelagatran), 17 investigated oral factor Xa inhibitors (eight rivaroxaban, five apixaban and four edoxaban) and one three-arm trial investigated both a DTI (dabigatran) and factor Xa inhibitor (rivaroxaban). Overall, the studies were of good methodological quality. Meta-analysis comparing DTIs to conventional anticoagulation showed no clear difference in the rate of recurrent VTE (odds ratio (OR) 1.17, 95% confidence interval (CI) 0.83 to 1.65; 3 studies, 5994 participants; moderate-certainty evidence), recurrent DVT (OR 1.11, 95% CI 0.74 to 1.66; 3 studies, 5994 participants; moderate-certainty evidence), fatal PE (OR 1.32, 95% CI 0.29 to 6.02; 3 studies, 5994 participants; moderate-certainty evidence), non-fatal PE (OR 1.29, 95% CI 0.64 to 2.59; 3 studies, 5994 participants; moderate-certainty evidence) or all-cause mortality (OR 0.66, 95% CI 0.41 to 1.08; 1 study, 2489 participants; moderate-certainty evidence). DTIs reduced the rate of major bleeding (OR 0.58, 95% CI 0.38 to 0.89; 3 studies, 5994 participants; high-certainty evidence). For oral factor Xa inhibitors compared with conventional anticoagulation, meta-analysis demonstrated no clear difference in recurrent VTE (OR 0.85, 95% CI 0.71 to 1.01; 13 studies, 17,505 participants; moderate-certainty evidence), recurrent DVT (OR 0.70, 95% CI 0.49 to 1.01; 9 studies, 16,439 participants; moderate-certainty evidence), fatal PE (OR 1.18, 95% CI 0.69 to 2.02; 6 studies, 15,082 participants; moderate-certainty evidence), non-fatal PE (OR 0.93, 95% CI 0.68 to 1.27; 7 studies, 15,166 participants; moderate-certainty evidence) or all-cause mortality (OR 0.87, 95% CI 0.67 to 1.14; 9 studies, 10,770 participants; moderate-certainty evidence). Meta-analysis showed a reduced rate of major bleeding with oral factor Xa inhibitors compared with conventional anticoagulation (OR 0.63, 95% CI 0.45 to 0.89; 17 studies, 18,066 participants; high-certainty evidence). AUTHORS' CONCLUSIONS: The current review suggests that DOACs may be superior to conventional therapy in terms of safety (major bleeding), and are probably equivalent in terms of efficacy. There is probably little or no difference between DOACs and conventional anticoagulation in the prevention of recurrent VTE, recurrent DVT, pulmonary embolism and all-cause mortality. DOACs reduced the rate of major bleeding compared to conventional anticoagulation. The certainty of evidence was moderate or high.

Meta-Analysis
BACKGROUND
This review evaluated the efficacy and safety of a combination therapy comprising a sodium-glucose cotransporter type 2 inhibitor (SGLT2i) and dipeptidyl peptidase-4 inhibitor (DPP4i) in type 2 diabetes.
METHODS
A literature search through to May 2017 was carried out of PubMed, Embase and the Cochrane Central Register of Controlled Trials. Studies were eligible if they were randomized controlled trials (RCTs) comparing SGLT2i plus DPP4i (SGLT2i/DPP4i) against DPP4i±placebo or SGLT2i±placebo and published in English. The primary outcome was change in HbA from baseline.
RESULTS
Eight RCTs comparing SGLT2i/DPP4i and DPP4i, and five RCTs comparing SGLT2i/DPP4i and SGLT2i, with three RCTs involving both comparisons, were included in the present review. SGLT2i/DPP4i resulted in a greater mean HbA reduction [weighted mean difference (WMD]): -0.62%] than did DPP4i alone, which was a much less marked reduction (WMD: -0.35%) than with SGLT2i alone. Also, significant differences in body weight loss from baseline were observed only with SGLT2i/DPP4i vs. DPP4i, but not vs. SGLT2i. The risk of hypoglycaemic events was low and similar between treatment groups. When subjects were stratified based on baseline HbA, any reduction by SGLT2i/DPP4i in relation to DPP4i was proportional to baseline HbA levels. However, compared with SGLT2i, HbA reductions with SGLT2i/DPP4i were modest regardless of baseline HbA.
CONCLUSION
Combination therapy with SGLT2i and DPP4i is both efficacious and safe. In particular, a marked additional glucose-lowering effect is evident when SGLT2i is combined with or added to DPP4i, and not vice versa. However, baseline HbA determined the additional glucose-lowering effects of SGLT2i in combined treatment with DPP4i.

Meta-Analysis Review
CONTEXT
Patients with HIV may have increased risk of atherosclerotic cardiovascular disease owing to multiple biological mechanisms.
OBJECTIVE
To evaluate the evidence for subclinical atherosclerosis among patients with HIV.
DESIGN
Systematic review of observational studies.
DATA SOURCES
We searched Medline, Cochrane DSR, ACP Journal Club, DARE, CMR, HTA, NHSEED, Embase and the Cochrane Controlled Trials Register for studies published before November 2008.
STUDY SELECTION
Eligible studies were cross-sectional, cohort, or case-control studies reporting carotid ultrasound intima-media thickness (CIMT), focal plaque incidence, or coronary artery calcium (CAC), as determined by HIV positivity or protease inhibitor (PI) exposure.
DATA EXTRACTION
Two independent reviewers abstracted data using a standardised form. The primary outcome was weighted mean difference (WMD) for CIMT comparing HIV positive versus negative patients. Other outcomes included WMD by PI exposure and the odds ratio (OR) for a focal carotid plaque or CAC. Data from six cross-sectional, seven case-control and 13 cohort studies were included, involving 5456 HIV positive and 3600 HIV negative patients.
RESULTS
The weighted mean CIMT was 0.04 mm thicker among patients with HIV than among non-HIV patients (95% CI 0.02 to 0.06; p<0.001). HIV positivity was not associated with carotid plaque or CAC. PI exposure did not significantly affect CIMT, carotid plaque, or CAC. There was evidence of publication bias and stratified analysis and meta-regression showed outcomes were influenced by study design, age, gender and smoking. However, HIV positivity slightly increased CIMT even after sensitivity analyses.
CONCLUSIONS
HIV infection and PI exposure are not strong independent risk factors for subclinical atherosclerosis. Confounding may contribute to overestimation of the risk associated with HIV and PI exposure.

Meta-Analysis
OBJECTIVE
The aim of this study was to determine the impact of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor use on incident sepsis and other severe infections.
METHODS
We searched PubMed, EMBASE, CENTRAL, and ClinicalTrial.gov up to September 14, 2021, for double-blind, placebo-controlled randomized trials of alirocumab, evolocumab, or inclisiran with >100 participants in each arm and report of serious adverse events related to infection. Data were synthesized with the fixed-effect Mantel-Haenszel model to generate risk ratios (RRs) with 95% confidence intervals (CIs) of each outcome for PCSK9 inhibitor versus placebo. Main outcome was sepsis. Other outcomes were total severe infections, severe bacterial and viral infections, and severe organ system-specific infections including respiratory tract, gastrointestinal, and genitourinary tract infections.
RESULTS
A total of 20 studies of 64,984 participants were included (alirocumab: n = 7; evolocumab: n = 9; inclisiran: n = 4). Sepsis was reported in 292 (0.51%) participants from 11 trials (PCSK9 inhibitor 0.47%; placebo 0.56%). PCSK9 inhibitor use was not associated with risk of sepsis compared with placebo (Summary RR: 0.85, 95% CI: 0.67-1.07, P = .16); nor was it associated with any severe infection (0.96, 95% CI: 0.89-1.03), severe bacterial (0.96, 95% CI: 0.81-1.14) and viral infections (1.01, 95% CI: 0.77-1.33); nor with any severe organ system-specific infection (all P values >.05). The between-study heterogeneity in all analyses was small.
CONCLUSION
There was neither a beneficial nor a harmful association between PCSK9 inhibitors and risk of sepsis or severe infections. These findings provide reassurance regarding the safety of PCSK9 inhibitors in patients who are concerned about potential drug side effects related to infections.

Meta-Analysis Review
Maternal antiretroviral treatment for HIV infection and risk of small-for-gestational-age birth: A systematic review and meta-analysis of protease inhibitor-based treatment and timing of treatment.
BACKGROUND
Data indicate that certain combination antiretroviral treatment (cART) regimens, particularly protease inhibitor (PI)-based regimens, and cART initiation before conception may be associated with adverse pregnancy outcomes. The risk of having a small-for-gestational-age (SGA) infant was examined among pregnant HIV-infected mothers on 1) PI-based compared to non-PI-based cART, and 2) any cART initiated before compared to after conception.
METHODS
A search was conducted using PubMed, Embase, and the Cochrane Library, and a systematic review was performed of studies published since Dec 1, 1995. Effect estimates with 95% confidence intervals (CIs) were extracted and meta-analyses with random-effects models were conducted. The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation tool.
FINDINGS
Of 783 identified studies, 28 fulfilled the inclusion criteria. Meta-analysis indicated that PI-based cART was associated with a possible slightly increased risk of SGA compared with non-PI-based cART (pooled odds ratio [OR]: 1·09; CI: 0·76, 1·55). Initiation of cART before conception was also associated with a possible slightly increased risk of SGA compared with after conception (pooled OR: 1·08; CI: 0·95, 1·22). The overall certainty of evidence was very low and low for the first and second research questions, respectively.
INTERPRETATION
Although the benefits of cART largely outweigh the risks, these findings indicate the possibility of slightly increased risks of having an SGA infant. This indicates that careful monitoring of fetuses exposed to PI-based cART or cART before pregnancy might be reasonable. Based on the uncertainty of evidence, further research may change this conclusion.
