Meta-Analysis
OBJECTIVE
Type 2 diabetes is more common in adults, but is becoming the major concern in children and adolescent recently. This study aimed to provide additional pharmaceutical management for children and adolescents with type 2 diabetes by assessing the efficacy and safety of several glucose-lowering drugs.
METHODS
Searches were performed in PubMed, Medline, Ovid, Cochrane Controlled Register of Trials (CENTRAL), and ClinicalTrials.gov that reported the efficacy and safety of drugs for children and adolescents with type 2 diabetes. Pooled effects were calculated by frequentist fixed effects network meta-analyses and additive network meta-analyses.
RESULTS
A total of 12 trials assessing eight glucose-lowering drugs were included, which compose of seven trials with monotherapy and five trials with combination therapies. Network meta-analysis results showed compared to placebo, saxagliptin+metformin (mean difference (MD) -1.91% [-2.85%, -0.97%]), liraglutide+metformin (MD -1.45% [-1.65%, -1.26%]), and liraglutide (MD -0.90% [-1.35%, -0.45%]) were the top 3 drugs that significantly reduced hemoglobin A1c (HbA1c). Sitagliptin+metformin, dapagliflozin, exenatide-2mcg, linagliptin-5mg, metformin, exenatide-5/10mcg, glimepiride, and sitagliptin also showed significant reduction in HbA1c. There were no significant differences between treatments in the incidence of adverse events, except that liraglutide+metformin had significant adverse effect such as abdominal pain. In addition, dapagliflozin, sitagliptin+metformin, and saxagliptin+metformin showed better efficacy compared with FDA-approved drugs.
CONCLUSIONS
The top 10 treatments of type 2 diabetes in children and adolescents aged 10-17 years were saxagliptin+metformin, liraglutide+metformin, liraglutide, dapagliflozin, exenatide-2 mcg, sitagliptin+metformin, linagliptin-5 mg, linagliptin-1 mg, metformin, and exenatide-5/10 mcg.

Review
BACKGROUND
Several treatment strategies for amyloid light chain cardiac amyloidosis (AL-CA) have been described in the literature; however, there is no consensus about the optimal approach to AL-CA.
OBJECTIVE
We conducted this systematic review to summarize current evidence from published studies about the safety and efficacy of various treatment regimens for patients with AL-CA, mainly focusing on autologous stem cell transplant (ASCT) and heart transplant.
METHODS
An electronic literature search of PubMed, Web of Science, Scopus, EBSCO, and CINAHL Plus was conducted through December 2019 using the relevant keywords and prespecified MeSH terminology. Records were screened, and eligible studies were selected and narratively discussed. Data on the hematologic and cardiac responses as well as the safety of the treatment regimens were extracted and synthesized narratively in the context of the systematic review.
RESULTS
Thirty published articles were included in this systematic review. The most commonly used first-line treatment in the included studies was bortezomib-based therapy followed by high-dose melphalan and ASCT, with recent evidence of improved outcome with the addition of daratumumab. Heart transplant was found to extend survival for selected patients who were not eligible for ASCT; however, it was found to affect the patients' tolerance of further chemotherapy in some studies. Published data on longterm outcomes with immunomodulatory agents were scarce.
CONCLUSION
Current evidence suggests several possible regimens for the treatment of AL-CA. Effective treatment approaches for AL-CA include induction therapy with bortezomib-based or immunotherapy-based combinations in moderate/severe forms of cardiac involvement, followed by high-dose melphalan and ASCT in eligible patients, and heart transplant for selected severe cases. Therefore, we highlight the necessity of conducting well-designed, randomized controlled trials to provide evidence about the efficacy of these drugs with respect to ASCT.

Meta-Analysis Review
BACKGROUND
Suboptimal exposure to antituberculosis (anti-TB) drugs has been associated with unfavourable treatment outcomes. We aimed to investigate estimates and determinants of first-line anti-TB drug pharmacokinetics in children and adolescents at a global level.
METHODS
We systematically searched MEDLINE, Embase and Web of Science (1990-2021) for pharmacokinetic studies of first-line anti-TB drugs in children and adolescents. Individual patient data were obtained from authors of eligible studies. Summary estimates of total/extrapolated area under the plasma concentration-time curve from 0 to 24 h post-dose (AUC) and peak plasma concentration ( ) were assessed with random-effects models, normalised with current World Health Organization-recommended paediatric doses. Determinants of AUC and were assessed with linear mixed-effects models.
RESULTS
Of 55 eligible studies, individual patient data were available for 39 (71%), including 1628 participants from 12 countries. Geometric means of steady-state AUC were summarised for isoniazid (18.7 (95% CI 15.5-22.6) h·mg·L), rifampicin (34.4 (95% CI 29.4-40.3) h·mg·L), pyrazinamide (375.0 (95% CI 339.9-413.7) h·mg·L) and ethambutol (8.0 (95% CI 6.4-10.0) h·mg·L). Our multivariate models indicated that younger age (especially <2 years) and HIV-positive status were associated with lower AUC for all first-line anti-TB drugs, while severe malnutrition was associated with lower AUC for isoniazid and pyrazinamide. -acetyltransferase 2 rapid acetylators had lower isoniazid AUC and slow acetylators had higher isoniazid AUC than intermediate acetylators. Determinants of were generally similar to those for AUC.
CONCLUSIONS
This study provides the most comprehensive estimates of plasma exposures to first-line anti-TB drugs in children and adolescents. Key determinants of drug exposures were identified. These may be relevant for population-specific dose adjustment or individualised therapeutic drug monitoring.

Review
BACKGROUND AND AIMS
Lobeglitazone (LGZ), a newly researched thiazolidinedione (TZD) thought to have lesser side effects compared with pioglitazone (PGZ), has been recently approved for the treatment of type 2 diabetes (T2D) in India. We aim to conduct an updated systematic review of LGZ to critically appraise its efficacy and safety in the context of PGZ.
METHODS
A systematic literature search was carried out in the electronic database of PubMed until Jan 15, 2023, using specific keywords and MeSH terms. All studies which evaluated LGZ in people with T2D were retrieved and data were synthesized with regard to its efficacy and safety. A comparative critical appraisal was additionally made in the context of PGZ in T2D.
RESULTS
Four randomized controlled, one prospective observational, and two real-world studies have evaluated the safety and efficacy of LGZ against placebo or active comparators either as monotherapy or in combination therapy. HbA1c reduction with LGZ 0.5 mg was superior to the placebo but similar to PGZ 15 mg and sitagliptin (SITA) 100 mg. Weight gain with LGZ was significantly higher compared to placebo and SITA but similar to PGZ. Edema was more frequently observed with LGZ compared to placebo, PGZ, and SITA.
CONCLUSION
No substantial evidence is yet available that suggests LGZ could be a better alternative to PGZ both in the context of glycemic or extra-glycemic effects. At least in the short-term, adverse events of LGZ are indifferent from PGZ. More data is additionally needed to claim any advantage of LGZ over PGZ.

Meta-Analysis
BACKGROUND/OBJECTIVE
There have been a number of case reports and small clinical series reporting the potential association between dipeptidyl peptidase-4 inhibitors (DPPIs) for diabetes and the onset of bullous pemphigoid (BP). The aim of this study was to assess the association between DPPI use and BP, and whether this varied according to DPPI type.
METHODS
We performed a systematic review and meta-analysis according to PRISMA guidelines. We identified five studies with cases and controls. We performed unadjusted and adjusted meta-analyses to assess the potential association.
RESULTS
Adjusted meta-analysis revealed significant association between DPPI use and BP (OR 2.13, 95% CI 1.59-2.86, I = 46%, P < 0.00001). This association was stronger between vildagliptin and BP (OR 5.08, 95% CI 1.70-15.19, P = 0.004) compared to linagliptin (OR 2.87, 95%CI 1.06-7.79, P = 0.04), and no association was found between sitagliptin and BP (OR 1.29, 95%CI 0.79-2.08, P = 0.31). Subgroup analysis demonstrated that the association between DPPI use and BP remained significant in males (OR 2.35, 95% CI 1.46-3.78, P = 0.0005) and females (OR 1.88, 95%CI 1.10-3.22, P = 0.02).
CONCLUSIONS
Limitations were that studies reviewed were retrospective by design which are susceptible to bias and lack of randomisation. Our adjusted analysis supports a significant association between DPPI use and onset of bullous pemphigoid. Vildagliptin had the highest odds of BP. These findings have clinical implications for dermatologists and the management of patients with diabetes and being treated with DPPI agents.

Review
INTRODUCTION
Drug-induced thrombocytopenia is a known adverse event of several drugs. Antitubercular therapy (ATT) is rarely reported but important cause of thrombocytopenia. The present review aimed to understand the profile of thrombocytopenia caused by first-line ATT i.e. isoniazid, rifampicin, pyrazinamide, and ethambutol.
MATERIALS AND METHODS
We screened case reports, case series, and letter-to-editor from databases, like Pubmed/MEDLINE, Ovid, and EMBASE from 1970 to 2021. The PRISMA guidelines were followed in the present systematic review.
RESULTS
Categorical data were expressed as n (%) and quantitative data were expressed as median (IQR). After applying the inclusion/exclusion criteria, 17 case reports and 7 letters to the editor were selected for the present review. Rifampicin was most frequently associated with thrombocytopenia (65%). A median (IQR) drop to 20,000 (49,500) platelets/mm3 was observed. Anti-rifampicin associated antibodies and anti-dsDNA positivity were found in six studies. Except for two, all patients responded to symptomatic treatment.
DISCUSSION
ATT-induced thrombocytopenia can be life-threatening and require hospitalization. Clinicians should be aware of the association of ATT with thrombocytopenia and should take appropriate measures for patient management.
CONCLUSION
This review provides clinicians a comprehensive picture of adverse effects and their management in ATT induced thrombocytopenia.

Meta-Analysis
AIMS/INTRODUCTION
The optimal therapy for latent autoimmune diabetes in adults (LADA) remains undefined. Increasing evidence has shown that sitagliptin and insulin treatment can benefit patients with LADA, but the efficacy still lacks systematic evaluation. We carried out this systematic review and meta-analysis to summarize the current data on the efficacy and safety of sitagliptin combined with insulin on LADA, providing a reliable reference for the effective therapeutic treatment of LADA patients.
MATERIALS AND METHODS
We retrieved the literature in PubMed, Cochrane Library, Embase, Web of Science and CNKI from inception to August 2021. Randomized controlled trials comparing the effects of sitagliptin plus insulin with insulin alone in LADA patients were identified. The outcome measures included parameters of glycemic control, β-cell function, body mass index and adverse events. The Review Manager 5.2 and Stata 14.0 were utilized for data analysis.
RESULTS
Eight randomized controlled trials involving 295 participants were identified. Sitagliptin and insulin treatment lowered hemoglobin A1c (weighted mean difference -0.36, 95% confidence interval -0.61 to -0.10, I = 91.6%), increased fasting C-peptide (weighted mean difference 0.08, 95% confidence interval -0.02 to 0.17, I = 88.8%) and had fewer adverse events compared with insulin alone. The inter-study heterogeneity, potential publication bias and other factors might interpret asymmetrical presentation of funnel plots. There was no significant association between sitagliptin plus insulin treatment and levels of hemoglobin A1c or fasting C-peptide, regardless of the duration of intervention and sample size.
CONCLUSIONS
Sitagliptin combined with insulin can achieve better glycemic control and improve islet β-cell function with lower incidence of hypoglycemia compared with insulin alone, which provides an effective and tolerated therapeutic regimen for LADA patients. However, further well-designed and rigorous randomized controlled trials are required to validate this benefit due to the limited methodology quality of included trials.

Meta-Analysis
The novel coronavirus outbreak began in late December 2019 and rapidly spread worldwide, critically impacting public health systems. A number of already approved and marketed drugs are being tested for repurposing, including Favipiravir. We aim to investigate the efficacy and safety of Favipiravir in treatment of COVID-19 patients through a systematic review and meta-analysis. This systematic review and meta-analysis were reported in accordance with the PRISMA statement. We registered the protocol in the PROSPERO (CRD42020180032). All clinical trials which addressed the safety and efficacy of Favipiravir in comparison to other control groups for treatment of patients with confirmed infection with SARS-CoV2 were included. We searched electronic databases including LitCovid/PubMed, Scopus, Web of Sciences, Cochrane, and Scientific Information Database up to 31 December 2020. We assessed the risk of bias of the included studies using Cochrane Collaboration criteria. All analyses were performed using the Comprehensive Meta-Analysis software version 2, and the risk ratio index was calculated. Egger and Begg test was used for assessing publication bias. Nine studies were included in our meta-analysis. The results of the meta-analysis revealed a significant clinical improvement in the Favipiravir group versus the control group during seven days after hospitalization (RR = 1.24, 95% CI: 1.09-1.41; P = 0.001). Viral clearance was more in 14 days after hospitalization in Favipiravir group than control group, but this finding marginally not significant (RR = 1.11, 95% CI: 0.98-1.25; P = 0.094). Requiring supplemental oxygen therapy in the Favipiravir group was 7% less than the control group, (RR = 0.93, 95% CI: 0.67-1.28; P = 0.664). Transferred to ICU and adverse events were not statistically different between two groups. The mortality rate in the Favipiravir group was approximately 30% less than the control group, but this finding not statistically significant. Favipiravir possibly exerted no significant beneficial effect in the term of mortality in the general group of patients with mild to moderate COVID-19. We should consider that perhaps the use of antiviral once the patient has symptoms is too late and this would explain their low efficacy in the clinical setting.

Review
Pyrazinamide (PZA) is a first-line antituberculosis drug with potent sterilising activity. Variability in drug exposure may translate into suboptimal treatment responses. This systematic review, conducted according to PRISMA guidelines, aimed to evaluate the concentration-effect relationship. In vitro/in vivo studies had to contain information on the infection model, PZA dose and concentration, and microbiological outcome. Human studies had to present information on PZA dose, measures of drug exposure and maximum concentration, and microbiological response parameter or overall treatment outcome. A total of 34 studies were assessed, including in vitro (n = 2), in vivo (n = 3) and clinical studies (n = 29). Intracellular and extracellular models demonstrated a direct correlation between PZA dose of 15-50 mg/kg/day and reduction in bacterial count between 0.50-27.7 log CFU/mL. Consistent with this, higher PZA doses (>150 mg/kg) were associated with a greater reduction in bacterial burden in BALB/c mice models. Human pharmacokinetic studies displayed a linear positive correlation between PZA dose (i.e. 21.4-35.7 mg/kg/day) and drug exposure (AUC range 220.6-514.5 mg·h/L). Additionally, human studies confirmed a dose-effect relationship, with an increased 2-month sputum culture conversion rate at AUC/MIC targets of 8.4-11.3 with higher exposure/susceptibility ratios leading to greater efficacy. A 5-fold variability in AUC was observed at PZA dose of 25 mg/kg. A direct concentration-effect relationship and increased treatment efficacy with higher PZA exposure to susceptibility ratios was observed. Taking into account variability in drug exposure and treatment response, further studies on dose optimisation are justified.

Review
Multiple myeloma (MM) is a clonal plasma cell tumor originating from a post-mitotic lymphoid B-cell lineage. Bortezomib(BTZ), a first-generation protease inhibitor, has increased overall survival, progression-free survival, and remission rates in patients with MM since its clinical approval in 2003. However, the use of BTZ is challenged by the malignant features of MM and drug resistance. Polyphenols, classified into flavonoid and non-flavonoid polyphenols, have potential health-promoting activities, including anti-cancer. Previous preclinical studies have demonstrated the anti-MM potential of some dietary polyphenols. Therefore, these dietary polyphenols have the potential to be alternative therapies in anti-MM treatment regimens. This systematic review examines the synergistic effects of flavonoids and non-flavonoid polyphenols on the anti-MM impacts of BTZ. Preclinical studies on flavonoids and non-flavonoid polyphenols-BTZ synergism in MM were collected from PubMed, Web of Science, and Embase published between 2008 and 2020. 19 valid preclinical studies (Published from 2008 to 2020) were included in this systematic review. These studies demonstrated that eight flavonoids (icariin, icariside II, (-)-epigallocatechin-3-gallate, scutellarein, wogonin, morin, formononetin, daidzin), one plant extract rich in flavonoids (Punica granatum juice) and four non-flavonoid polyphenols (silibinin, resveratrol, curcumin, caffeic acid) synergistically enhanced the anti-MM effect of BTZ. These synergistic effects are mediated through the regulation of cellular signaling pathways associated with proliferation, apoptosis, and drug resistance. Given the above, flavonoids and non-flavonoid polyphenols can benefit MM patients by overcoming the challenges faced in BTZ treatment. Despite the positive nature of this preclinical evidence, some additional investigations are still needed before proceeding with clinical studies. For this purpose, we conclude by providing some suggestions for future research directions.
