Background and Clinical Significance: Statins are widely prescribed for cardiovascular risk reduction and generally demonstrate a favorable safety profile. While myalgia and elevations in liver enzymes are well-recognized adverse effects, headaches are less commonly reported and often underrecognized in clinical practice. This may result in unnecessary diagnostic evaluations, increased healthcare costs, and delayed identification of the underlying cause. Case Presentation: We describe an adult patient who developed intractable headaches that emerged after many years of statin therapy. The headaches persisted despite conventional analgesic treatment and resolved completely following discontinuation of the statin. Secondary causes were excluded, and comorbid conditions were systematically ruled out. Statin-associated headache is uncommon but clinically relevant. Proposed mechanisms include nitric-oxide-mediated vasodilation, central effects of lipophilic statins, and mitochondrial involvement. In this case, the patient was taking metoprolol succinate, lisinopril, simvastatin, clopidogrel, and tamsulosin. Except for lisinopril, none of the other comedications are strongly linked to new-onset headaches. Holding it did not resolve his headache, making simvastatin the most plausible contributor. This was confirmed by resolution of headache through its discontinuation. Because such headaches may be overlooked, clinicians should consider a statin-related cause when symptoms begin after initiation and may manage this by switching to a hydrophilic statin or using alternative lipid-lowering therapy. Conclusions: Clinicians should remain vigilant about the possibility of statin-induced headache, even in long-term users. Early recognition can prevent unnecessary diagnostic investigations, expedite symptom resolution, and support optimal management of both cardiovascular risk and treatment-related adverse effects.

Background/Objectives: In spite of substantial treatment progress, cancer persists as a leading health challenge. With the slow advancement in developing new anticancer agents, drug repurposing provides a promising strategy to enhance cancer therapy. This study investigates the antiproliferative and antimetastatic properties of two 3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, atorvastatin and rosuvastatin, which represent lipophilic and hydrophilic statins, respectively. Methods: Growth inhibition was evaluated in a panel of human cancer cells using the standard MTT assay. Apoptotic effects were determined through flow cytometry, caspase-3 activity assay, mitochondrial membrane potential assessment, and Hoechst/Propidium iodide fluorescent double staining. Migration and invasion assays were conducted using wound-healing and Boyden chamber assays, respectively. Results: Atorvastatin demonstrated more pronounced growth-inhibitory effects than rosuvastatin, with the IC₅₀ values in the range of 2.57–61.01 µM. Atorvastatin exhibited both biochemical and morphological indicators of apoptosis. Flow cytometry revealed cell cycle disruptions and increased sub-G1 apoptotic populations in HPV-positive oral squamous carcinoma cells (UPCI-SCC-154) and HPV-negative cervical cancer cells (C33A). Atorvastatin also significantly inhibited cell migration and invasion in the tested cell lines. Conclusions: Our results highlight the promising anticancer potential of atorvastatin in cervical cancer and oral squamous carcinoma cells. However, these findings are limited to in vitro models and warrant further in vivo validation. Full article

Background/Objectives: Colorectal cancer (CRC) is a growing public health concern in South Korea, with incidence rising alongside dyslipidemia. Statins, widely prescribed for lipid control, have been proposed to reduce CRC risk, but evidence remains inconsistent, particularly in Asian populations. Methods: Using Korean National Health Insurance Service data (2002–2019), we conducted a nested case–control study of 9920 CRC patients and 39,680 matched controls. To reduce confounding, we applied a matching process with a propensity score and overlap weighting based on demographic and clinical variables. Statin use within two years before CRC diagnosis was categorized by type (lipophilic vs. hydrophilic) and duration. Lifestyle data such as smoking and diet were not available. Results: Short-term statin use was associated with a 17% reduced CRC risk, particularly in younger, metabolically healthier Korean males. Lipophilic statins were consistently associated with lower CRC risk and mortality. However, hydrophilic statins showed mixed results: while short-term use lowered CRC risk, long-term use was linked to increased all-cause mortality. These associations varied by patient subgroup. Conclusion: Among Korean adults, short-term statin use—especially lipophilic agents—was associated with favorable CRC outcomes. However, the observational design, the absence of lifestyle data, and increased mortality linked to long-term hydrophilic statin use limit causal interpretation. Further research using clinically enriched or prospective datasets is warranted to validate these findings and guide personalized preventive strategies. Full article

Background/Objectives: Psoriasis is a chronic inflammatory disease that significantly impacts physical and emotional health. Statins, primarily used as lipid-lowering drugs, have also demonstrated anti-inflammatory effects. While some studies suggest that statins may improve psoriasis symptoms, the findings have been inconsistent. This study aims to investigate the association between prior statin use and the onset of psoriasis in a Korean population, focusing on individuals with dyslipidemia to minimize confounding factors. Methods: Using the Korean Health Insurance database (2002–2019), a nationwide nested case-control study was conducted, enrolling 8285 participants with psoriasis and 33,140 controls, matched 1:4 for sex, age, residence, and income through propensity scoring. Results: Adjusted odds ratios revealed significantly lower risks of psoriasis among short-term statin users (OR = 0.70, 95% CI = 0.66–0.74) and long-term users (OR = 0.77, 95% CI = 0.73–0.82) than in nonusers. This trend was consistent for both lipophilic and hydrophilic statins, and across subgroup analyses. Conclusions: These findings suggest that statins may reduce the incidence of psoriasis. However, further research is needed to assess their effects on psoriasis progression and severity. Full article

Background/Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the leading cause of chronic liver disease globally. The impact of statins on liver fibrosis severity in MASLD individuals remains uncertain, despite their known cardiovascular benefits. Methods: A cross-sectional study was performed utilizing the National Health and Nutrition Examination Survey (NHANES) database from 2017 to 2018. MASLD was defined by hepatic steatosis (controlled attenuation parameter [CAP] score ≥ 288 dB/m) without other etiologies. Using inverse probability treatment weighting to minimize confounding, we examined the association between statin use and MASLD outcomes, including at-risk steatohepatitis (FibroScan-aspartate aminotransferase [AST] [FAST] score ≥ 0.67), significant and advanced fibrosis (liver stiffness measurement [LSM] ≥ 8.8 kilopascals [kPa] and ≥ 11.7 kPa), and advanced fibrosis (AGILE 3+ score ≥ 0.68). Results: Of 1283 MASLD patients, 376 were prescribed statins within the past 30 days. After adjustment for confounders, statin use was significantly associated with reduced risks of at-risk steatohepatitis, significant fibrosis, and high AGILE 3+ scores, with odds ratios (ORs) of 0.29 (95% CI: 0.01 to 0.87), 0.54 (95% CI: 0.31 to 0.95), and 0.41 (95% CI: 0.22 to 0.75), respectively. However, a subgroup analysis showed this effect persisted only with lipophilic statins. Conclusions: Statin use was associated with reduced steatohepatitis and fibrosis in patients with MASLD, supported by robust causal inference and vibration-controlled transient elastography-derived scores.

Despite growing interest in the preventive effects of statins, as lipid-lowering agents, on migraine attacks, comprehensive nationwide studies comparing migraine likelihood between statin users and controls are lacking. Our nested case–control study within the Korean National Health Insurance Service-Health Screening Cohort (2002–2019) investigated this association using 38,957 migraine patients and 155,828 controls, considering migraine subtypes (with/without aura) and statin types (lipophilic vs. hydrophilic). Using propensity score matching and adjusting for confounders, statin use was linked to reduced migraine likelihood overall (odds ratio (OR) 0.93), particularly for migraines with aura (OR 0.75) and without aura (OR 0.94). Lipophilic statins were effective for both subtypes, while hydrophilic statins mainly reduced the likelihood of migraines without aura. Subgroup analyses showed consistent benefits across demographics, but varied effectiveness based on weight, smoking, alcohol use, hemoglobin levels, and dyslipidemia history. In summary, this nationwide cohort study suggests that statin use may reduce migraine likelihood among Korean adults across diverse demographics and clinical profiles, but varied effectiveness based on certain lifestyle and comorbidity factors underscores the importance of considering individual patient profiles when assessing the potential benefits of statin therapy for migraine prevention.

The HMG-CoA reductase inhibitors, statins, are drugs used globally for lowering the level of cholesterol in the blood. Different clinical studies of statins in cancer patients have indicated a decrease in cancer mortality, particularly in patients using lipophilic statins compared to those on hydrophilic statins. In this paper, we selected two structurally different statins (simvastatin and pravastatin) with different lipophilicities and investigated their effects on the proliferation and apoptosis of hepatocellular carcinoma cells. Lipophilic simvastatin highly influences cancer cell growth and survival in a time- and concentration-dependent manner, while pravastatin, due to its hydrophilic structure and limited cellular uptake, showed minimal cytotoxic effects.

Statins, widely prescribed for lipid disorders, primarily target 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase competitively and reversibly, resulting in reduced low-density lipoprotein cholesterol (LDL-C). This mechanism proves effective in lowering the risk of lipid-related diseases such as ischemic cerebrovascular and coronary artery diseases. Beyond their established use, statins are under scrutiny for potential applications in treating bone diseases. The focus of research centers mainly on simvastatin, a lipophilic statin demonstrating efficacy in preventing osteoporosis and aiding in fracture and bone defect healing. Notably, these effects manifest at elevated doses (20 mg/kg/day) of statins, posing challenges for systematic administration due to their limited bone affinity. Current investigations explore intraosseous statin delivery facilitated by specialized carriers. This paper outlines various carrier types, characterizing their structures and underscoring various statins’ potential as local treatments for bone diseases. Full article

We aimed to evaluate the survival benefits of coadministering statins and multityrosine kinase inhibitors (TKIs) in patients with advanced hepatocellular carcinoma (HCC). Data from the Health Insurance Review and Assessment Service in Korea (2010–2020) were utilized. Statin use (≥28 cumulative defined daily doses) was analyzed, with 1534 statin users matched to 6136 non-users (1:4 ratio) using propensity scores. Primary and secondary outcomes were overall survival (OS) and progression-free survival (PFS). Statin use significantly improved OS (hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.72–0.82, p < 0.001) and PFS (HR 0.78, 95% CI 0.74–0.84, p < 0.001). Continuous or post-TKI statin users had better OS, while discontinuation after TKI use led to poorer OS. Both lipophilic and hydrophilic statins improved OS and PFS, particularly with ≥730 cumulative defined daily doses. In conclusion, combining statins and TKIs in patients with advanced HCC yielded significant survival benefits, influenced by statin dosage and duration. Continuous statin administration post-TKI treatment is crucial for improving outcomes in patients with HCC. Full article

Pre-clinical studies from the recent past have indicated that senescent cells can negatively affect health and contribute to premature aging. Targeted eradication of these cells has been shown to improve the health of aged experimental animals, leading to a clinical interest in finding compounds that selectively eliminate senescent cells while sparing non-senescent ones. In our study, we identified a senolytic capacity of statins, which are lipid-lowering drugs prescribed to patients at high risk of cardiovascular events. Using two different models of senescence in human vascular endothelial cells (HUVECs), we found that statins preferentially eliminated senescent cells, while leaving non-senescent cells unharmed. We observed that the senolytic effect of statins could be negated with the co-administration of mevalonic acid and that statins induced cell detachment leading to anoikis-like apoptosis, as evidenced by real-time visualization of caspase-3/7 activation. Our findings suggest that statins possess a senolytic property, possibly also contributing to their described beneficial cardiovascular effects. Further studies are needed to explore the potential of short-term, high-dose statin treatment as a candidate senolytic therapy. Full article

This study aimed to evaluate the effect of statin solubility on the survival of patients undergoing hemodialysis (HD). This retrospective study used laboratory and clinical data from a national HD quality assessment program and claims data (n = 53,345). The use of statins was defined as prescription ≥30 days during 6 months of each HD quality assessment period. We divided the patients into three groups based on the use and solubility of statins: No group, patients without a prescription of statins (n = 37,944); Hydro group, patients with a prescription of hydrophilic statins (n = 2823); and Lipo group, patients with a prescription of lipophilic statins (n = 12,578). The 5-year survival rates in the No, Hydro, and Lipo groups were 69.6%, 67.9%, and 67.9%, respectively (p < 0.001 for the trend). Multivariable Cox regression analyses showed that the Lipo group had better patient survival than the No group. However, multivariable analyses did not show statistical significance between the Hydro and No or Lipo groups. In all subgroups based on sex, age, presence of diabetes mellitus, and heart disease, the Lipo group had better patient survival than the No group. We identified no significant association between hydrophilic and lipophilic statins and patient survival. However, patients taking lipophilic statins had a modest survival benefit compared with those who did not receive statins. Full article

Statins are common drugs that are clinically used to reduce elevated plasma cholesterol levels. Based on their solubility, statins are considered to be either hydrophilic or lipophilic. Amongst them, simvastatin has the highest lipophilicity to facilitate its ability to cross the blood-brain barrier. Recent studies have suggested that simvastatin could be a promising therapeutic option for different brain complications and diseases ranging from brain tumors (i.e., medulloblastoma and glioblastoma) to neurological disorders (i.e., Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease). Specific mechanisms of disease amelioration, however, are still unclear. Independent studies suggest that simvastatin may reduce the risk of developing certain neurodegenerative disorders. Meanwhile, other studies point towards inducing cell death in brain tumor cell lines. In this review, we outline the potential therapeutic effects of simvastatin on brain complications and review the clinically relevant molecular mechanisms in different cases. Full article

The present study evaluated the association of long-term statin use with the diagnosis and mortality of esophageal cancer in a Korean population. The Korean National Health Insurance Service-Health Screening Cohort from 2002 to 2019 was enrolled. Esophageal cancer patients were matched with control participants for demographic variables. The statin prescription histories were collected and grouped into <180 days, 180 to 545 days, and >545 days of duration. Propensity score overlap weighting was applied to minimize the bias between the esophageal cancer and control groups. The odds ratios (ORs) of the duration of statin use for esophageal cancer were analyzed using propensity score overlap weighted multivariable logistic regression analysis. The esophageal cancer group was classified as dead and surviving patients, and the ORs of the duration of statin use for the mortality of esophageal cancer were analyzed in an identical manner. Secondary analyses were conducted according to comorbid factors. Patients with esophageal cancer did not show lower odds for the duration of statin prescription in the overall study population (OR = 1.30, 95% CI = 1.03–1.65, p = 0.027 for 180 to 545 days and OR = 1.29, 95% CI = 1.08–1.55, p = 0.006 for >545 days). Subgroups of nonsmokers, past and current smokers, alcohol consumption ≥ 1 time a week, SBP < 140 mmHg and DBP < 90 mmHg, fasting blood glucose ≥ 100 mg/dL, total cholesterol ≥ 200 mg/dL, CCI score = 0, and nondyslipidemia history demonstrated low odds for the duration of statin prescription. Both types of statins, hydrophilic and lipophilic statins, were not related to a lower rate of esophageal cancer. The mortality of esophageal cancer was not associated with the duration of statin prescription. A subgroup with total cholesterol ≥ 200 mg/dL showed lower odds of statin prescription for mortality of esophageal cancer. The duration of statin prescription was not related to a lower rate or mortality of esophageal cancer in the adult Korean population. Full article

Heart failure (HF) and cancer have similar risk factors. HMG-CoA reductase inhibitors, also known as statins, are chemoprotective agents against carcinogenesis. We aimed to evaluate the chemoprotective effects of statins against liver cancer in patients with HF. This cohort study enrolled patients with HF aged ≥20 years between 1 January 2001 and 31 December 2012 from the National Health Insurance Research Database in Taiwan. Each patient was followed to assess liver cancer risk. A total of 25,853 patients with HF were followed for a 12-year period; 7364 patients used statins and 18,489 did not. The liver cancer risk decreased in statin users versus non-users (adjusted hazard ratio (aHR) = 0.26, 95% confidence interval (CI): 0.20–0.33) in the entire cohort in the multivariate regression analysis. In addition, both lipophilic and hydrophilic statins reduced the liver cancer risk in patients with HF (aHR 0.34, 95% CI: 0.26–0.44 and aHR 0.42, 95% CI: 0.28–0.54, respectively). In the sensitivity analysis, statin users in all dose-stratified subgroups had a reduced liver cancer risk regardless of age, sex, comorbidity, or other concomitant drug use. In conclusion, statins may decrease liver cancer risk in patients with HF. Full article

The correlation between statin use and the development of gallstone disease remains controversial. Existing data, primarily based on Caucasian populations, are biased, thus necessitating validation studies involving Asian cohorts. We conducted a nested case–control study using data from the Korean National Health Insurance Service Health Screening Cohort (2002–2019) to determine the likelihood of gallstone disease according to periods of previous statin use and type of statin. Among the 514,866 participants, 22,636 diagnosed with gallstones at ≥2 clinic visits (using the International Classification of Diseases, 10th revision, code K80) were matched 1:4 to 90,544 controls for age, sex, income, and residential area, and their statin prescription history for 2 years prior to the index date was examined. Propensity-score-weighted odds ratios (ORs) for gallstone disease were calculated using conditional logistic regression. Long-term use (>545 days) of any statin or lipophilic statins was associated with lower odds of incident gallstones (OR = 0.91, 95% confidence interval [CI] = 0.86–0.96, p < 0.001 and OR = 0.88, 95% CI = 0.83–0.93, p < 0.001, respectively) after adjusting for confounders. Short-term use (180–545 days) of any statin or hydrophilic statins was not statistically related to incident gallstones. In summary, prior statin medication, particularly long-term lipophilic statin use, may confer a preventive advantage against gallstone disease. Full article
