Meta-Analysis
OBJECTIVE
This meta-analysis aimed to evaluate the effect of pioglitazone on Parkinson's disease (PD) in diabetes patients.
METHODS
A study search was carried out in PubMed, Embase, and Web of Science databases from inception to July 22, 2021. The Newcastle-Ottawa scale was used to evaluate the quality of the eligible studies. The risk ratio (RR) and 95% confidence intervals (CI) were used as effect size indicators in this meta-analysis to evaluate the risk association between pioglitazone and PD. The Cochran's Q and I tests were used to assess statistical heterogeneity. A dose-response meta-analysis was conducted using the least squares trend estimation method.
RESULTS
Three studies were eligible for this meta-analysis. Compared with diabetes patients who did not use pioglitazone, there was a significant reduction in the risk of PD (RR of 0.87 [95 % CI 0.62-0.99, P = 0.039]) in pioglitazone users. No significant difference in PD risk was noted in diabetes patients taking 438 dose-duration-days (DDDs) of pioglitazone or lower compared with those who did not. When the DDD of pioglitazone was 438, the RR was 0.85 (95 % CI [0.72-1.00], P = 0.05). When the DDD of pioglitazone was > 438, the risk of PD in patients with diabetes was significantly decreased (P < 0.05) and showed an approximate linear correlation trend.
CONCLUSION
Pioglitazone administration in PD in diabetes patients is significantly associated with a decrease in the risk of PD.

Review
Modern diabetic treatment has gone beyond glycemic control, with the choice of different medications to attain therapeutic targets also affected by the risk of long-term outcomes and safety profiles. The effect of diabetes on increased morbidity and mortality and its relationship to cardiovascular outcomes and coronary artery diseases have driven recent diabetes studies toward medications that improve cardiovascular outcomes and reduce all-cause mortality. This is attained by holistically treating cardiovascular complications in type 2 diabetic patients beyond glycemic control. Moreover, both diabetes and pre-diabetes are considered risk factors for both microvascular and macrovascular cardiac events. Despite the fact that initial research acknowledged fluid retention as a safety issue in pioglitazone use, clinical trial data have not presented conclusive proof of a positive or negative impact on cardiac function. This comprehensive literature review aims to evaluate the effect of pioglitazone on all-cause mortality, hospitalizations for heart failure, and major adverse cardiovascular outcomes, including the individual outcomes of non-fatal stroke, non-fatal myocardial infarction, and cardiovascular mortality.

Frontiers in Endocrinology 2021To comprehensively evaluate and compare the therapeutic effects of various hypoglycemic agents in NAFLD patients with or without diabetes. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To comprehensively evaluate and compare the therapeutic effects of various hypoglycemic agents in NAFLD patients with or without diabetes.
METHODS
All literature from the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, and Clinical Trials was searched, and the language was limited to English. Two reviewers independently assessed study eligibility, continuous data extraction, and independent assessment of bias risk. Our primary outcomes were alanine aminotransferase (ALT), aspartate aminotransferase (AST) and triglyceride levels, while our secondary outcomes were high-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels, body weight, BMI, and fasting glucose and glycosylated hemoglobin (HbA1c) levels.
RESULTS
The review identified 20 eligible trials that met the inclusion criteria. We found that, compared to other drugs, thiazolidinediones, especially pioglitazone, had a greater effect on the levels of ALT (-8.01 (95% CI -14.3 to 2.02)) and AST (-5.0 (95% CI -9.21 to -1,22)) and other biological indicators, but they were also associated with an increased risk of weight gain (3.62 (95% CI 2.25 to 4.99) and increased BMI (0.59 (95% Cl -0.13 to 1.29). GLP1 RAs and metformin also had better therapeutic effects than other drugs as measured by the levels of ALT (liraglutide: -9.36 (95% Cl -18 to -0.34), metformin: -2.84 (95% CI -11.09 to 5.28)) and AST (liraglutide: -5.14 (95% CI -10.69 to 0.37), metformin: -2.39 (95% CI -7.55, 2.49)) and other biological indicators.
CONCLUSION
Despite the significant risk of weight gain, thiazolidinediones, especially pioglitazone, are beneficial in normalizing liver and glucose metabolism in NAFLD patients. In clinical practice, we believe that GLP1 RAs such as liraglutide and exenatide or metformin can be used in combination to offset the risk of weight gain associated with thiazolidinediones. However, long-term studies are still needed to verify the efficacy and safety of individual hypoglycemic agents.

Review
Diabetes mellitus (DM) is known to be a risk factor for dementia, especially in the elderly population, and close associations between diabetes and Alzheimer disease (AD) have been determined. Peroxisome proliferator-activated receptor-gamma (PPAR-γ) agonists are insulin-sensitising drugs. In addition to their anti-diabetic properties, their effectiveness in preventing and decreasing cognitive impairment are the most recent characteristics that have been studied. For this study, we conducted a systematic review and meta-analysis to critically analyse and evaluate the existing data on the effects of PPAR-γ agonist therapy on the cognitive status of patients. For this purpose, we first analysed both early intervention and later treatment with PPAR-γ agonists, according to the disease status. The involved studies indicated that early PPAR-γ agonist intervention is beneficial for patients and that high-dose PPAR-γ therapy may have a better clinical effect, especially in reversing the effects of cognitive impairment. Furthermore, the efficacy of pioglitazone (PIO) seems to be promising, particularly for patients with comorbid diabetes. PIO presented a better clinical curative effect and safety, compared with rosiglitazone (RSG). Thus, PPAR-γ agonists play an important role in the inflammatory response of AD or DM patients, and clinical therapeutics should focus more on relevant metabolic indices.

Can Pioglitazone Safeguard Patients of Lichen Planus Against Homocysteine Induced Accelerated Cardiovascular Aging and Reduced Myocardial Performance: A Systematic Review.
Lichen planus (L.P.) is a long-standing mucocutaneous inflammatory condition. A less familiar but essential illness association is increased arterial stiffness, endothelial dysfunction, and advanced atherosclerosis. Enhanced cardiac reconditioning and reduced performance of the heart have been suggested. Thiazolidinediones were commenced to manage hyperglycemia in diabetes mellitus. Recently, the class attained popularity after its action on vascular physiology was discovered. With this review, we attempted to explore whether an antidiabetic drug, pioglitazone (PIO), a peroxisome proliferator‑activated receptor γ (PPAR gamma) agonist, can defend patients of lichen planus against increased arterial stiffness and cardiac changes. We methodically screened numerous databases using focused words and phrases for relevant articles. After a comprehensive exploration, we applied the inclusion and exclusion criteria and performed a quality appraisal. Items retained were exhaustively studied. High homocysteine (HHcy) levels in lichen planus play a significant role in modifying the arteries and leading to their dysfunction. Not only does homocysteine affect the precursor cells, but it also increases the free radical damage. Arterial damage and upraised resistance encountered by the heart reduce its performance. After an exhaustive analysis, in our opinion, pioglitazone works in various miscellaneous ways to mitigate the homocysteine mediated changes. Early inclusion of the drug in managing patients with lichen planus seems promising in minimizing the harmful effects of high homocysteine. Evaluating the risk-benefit ratio, we believe that a trial of pioglitazone could be given to patients without underlying cardiac conditions.

Frontiers in Cardiovascular Medicine 2022To assess the impact of the HbA1c levels achieved with antidiabetic therapies (ADTs) on the risk of MACE.
AIM
To assess the impact of the HbA1c levels achieved with antidiabetic therapies (ADTs) on the risk of MACE.
METHODS
A systematic search was performed in PubMed, Cochrane, and ClinicalTrials. gov for RCTs published up to March 2022 reporting the occurrence of MACE and all-cause mortality in individuals with T2DM treated with all marketed ADTs, including a sample size ≥100 individuals in each study arm and follow-up ≥24 weeks. A systematic review and additive-effects network meta-analysis with random effects and a multivariate meta-regression were utilized to assess the impact of achieved HbA1c on incident MACE.
RESULTS
We included 126 RCTs with 143 treatment arms, 270,874 individuals, and 740,295 individuals-years who were randomized to an active treatment vs. control group. Among all ADTs, only therapy with SGLT2i, GLP1-RA, or pioglitazone similarly reduced the risk of MACE compared to placebo. The achievement of HbA1c ≤ 7.0% in RCTs with the 3 drug classes in the active arm was associated with an adjusted HR of 0.91 (95% CI 0.80, 0.97; = 0.017) compared with HbA1c>7.0%, without affecting all-cause mortality. These results, however, were not maintained among all ADTs.
CONCLUSIONS
Achieving lower glucose levels with SGLT2i, GLP1-RA, or pioglitazone is linearly associated with a reduced risk of MACEs, without affecting all-cause mortality.

Review
Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease, with an increasing prevalence in all regions of the world. Its spectrum includes hepatic steatosis (HS) and non-alcoholic steatohepatitis (NASH) with progression to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). NAFLD may represent the hepatic manifestation of the metabolic syndrome (MS), with a prevalence directly proportional to the prevalence of obesity and MS. The standard treatment for patients with NAFLD is lifestyle modification, which in medical practice has many limitations. To overcome them, numerous drugs with benefits in the prevention and treatment of the disease have been studied. Currently, the most used substances are vitamin E and Pioglitazone, with numerous benefits. Furthermore, new strategies and beneficial treatments are needed for the prevention of the disease, which is currently a priority in both the health and research fields. One of the most studied agents in the last decades has been ursodeoxycholic acid (UDCA), which is of great interest in the treatment of NAFLD due to its hepatoprotective effects.

Review
The aim of this review is to appraise the data from available randomized clinical trials (RCT) regarding the possible combinations of neuroleptic and non-antipsychotic treatment which could enhance antipsychotic therapy efficacy whilst simultaneously addressing somatic symptoms in individuals with schizophrenia. A systematic search of the PubMed database up to February 2022 was conducted. Inclusion criteria: randomized controlled trials using augmentation therapy in chronic schizophrenia in adults, written in English, and only studies with psychometric assessments of schizophrenia were incorporated. Exclusion criteria: non-clinical, first episode of schizophrenia, patients on medication other than antipsychotics augmented, and not adjunctive therapy. Overall, 37 studies of 1931 patients with schizophrenia who received a combination of antipsychotic medication with other drugs were selected. A statistically significant reduction of negative and positive symptoms of schizophrenia, measured with the PANSS scale, when using a combination of antipsychotic treatment along with aspirin, simvastatin, N-acetylcysteine, or pioglitazone was found. A combination of antipsychotic medication with aspirin, simvastatin, N-acetylcysteine, or pioglitazone seems to be effective in the reduction of symptoms of schizophrenia in adults, but long-term studies are required to confirm this effect.

BACKGROUND
Fatty liver is associated with obesity, type 2 diabetes, hyperlipidemia, hypertension, and metabolic syndrome. While there are no approved drugs for the treatment of nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis, strategies to ameliorate fatty liver often target these related diseases. We sought to determine if any medications approved by the US Food and Drug Administration to treat diabetes are helpful in reducing weight and improving steatohepatitis in patients with NAFLD.
METHODS
We conducted a systematic review of published and unpublished studies evaluating the comparative effectiveness and harms of diabetes medications for the treatment of NAFLD. We searched MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials through 3rd quarter, 2019 using terms for included drugs and indications.
RESULTS
We screened 1591 citations and included 18 trials of diabetes drugs to treat NAFLD. Studies of metformin found no difference from placebo in steatosis, fibrosis, NAFLD activity score, or resolution of NASH. While weight and glucose control were improved with metformin, it did not substantially impact liver disease. Studies of pioglitazone in NASH patients found benefits in liver function, liver fat, and NASH resolution, though significant increases in weight may be cause for concern. Evidence for other thiazolinediones was more limited and had somewhat mixed results, but findings were generally consistent with those for pioglitazone: liver fat and function and glucose measures improved, but weight also increased. We found some evidence that liraglutide improves liver fat, liver function, and HbA1c and is effective at resolving NASH and reducing weight. Exenatide performed less well but also resulted in significant reductions in liver fat and weight.
CONCLUSIONS
Consistent with existing clinical practice guidelines, which recommend lifestyle intervention and treatment for comorbidities related to fatty liver disease as first-line treatment, trial evidence supports the efficacy of some diabetes drugs (especially pioglitazone) in patients with NAFLD or NASH, though weight gain with some diabetes drugs may warrant caution. Larger trials are needed to better characterize the efficacy and harms of diabetes pharmacotherapy in these patients.

BACKGROUND With the expanding understanding of conditions contributing to heightened cardiovascular risk, emerging pathologies like nonalcoholic fatty liver disease (NAFLD) and polycystic ovary syndrome (PCOS) are being recognized as hepatic and ovarian manifestations of metabolic syndrome, respectively. This study aims to elucidate the recent advancements in our comprehension of the link between these conditions in the pediatric demographic, focusing on pathogenesis, incidence, diagnostic methods, and effective therapeutic strategies. MATERIAL AND METHODS A systematic review was conducted following the PRISMA 2020 guidelines, with a search of the PubMed database for eligible studies published in the ten years leading up to January 2023. RESULTS Out of 23 reports based on 16 original studies, we found a significantly higher prevalence of NAFLD in adolescents with PCOS compared to healthy controls. Factors such as increased de novo lipogenesis, alterations in gut microbiota, and a deficiency in growth differentiation factor-15 have been implicated in their pathogenesis. Additionally, novel biomarker S100A4, a clinical prediction score for hepatic steatosis in PCOS, and pharmacotherapy involving low-dose spironolactone, pioglitazone, and metformin have been proposed to enhance the management of these conditions. CONCLUSIONS A meticulous approach to the prevention, detection, and treatment of NAFLD in adolescents with PCOS is paramount to mitigate further complications. The study underlines the need for ongoing research to refine our understanding and management of these interconnected metabolic disorders.
