Association of patient, provider and facility related characteristics with statin associated side effects and statin use: Insight from the veteran's affairs healthcare system

Fatal hepatic failure following atorvastatin treatment: A case report

RATIONALE

Atorvastatin is a commonly used statin for the treatment of hypercholesterolemia in people at high risk for coronary, cerebrovascular, and peripheral artery disease. However, fatal liver failure due to atorvastatin treatment has been rarely reported, especially during the very short incubation period.

PATIENT CONCERNS

A 63-year-old male patient was admitted due to unexplained chest pain. After admission, his liver function had decreased < 24 hours after taking 20 mg tablets of atorvastatin due to lacunar infarction, which was improved after drug withdrawal. The treatment regimen was restarted 15 days later, but within 16 hours, the patient developed multiple organ failure, including liver failure and renal failure.

DIAGNOSES

The pathological results after 7 days indicated focal inflammatory necrosis, virus and autoimmune correlation tests were negative, which did not rule out drug-induced liver injury. Interventions: receiving artificial liver therapy, continuous renal replacement therapy and other organ support treatment.

OUTCOMES

The patient died 18 days after admission.

LESSONS

Statin idiosyncratic liver injury is very rare, but the consequences can be serious.

Glucagon-modified Liposomes Delivering Thyroid Hormone for Anti-obesity Therapy

BACKGROUND

Thyroid hormones (active form T3) are naturally potent compounds that influence energy expenditure, cholesterol metabolism, and fat oxidation. T3 would be an effective anti-obesity drug if it would not be delivered to the heart and bones, which leads to serious side effects, such as cardiovascular and bone thyrotoxicity, muscle wasting, and so on.

METHODS

In this study, we designed a targeted drug delivery system that is a glucagon-modified liposome to deliver T3 to the liver and adipose tissues.

RESULTS

The liposomes exhibited excellent properties, including uniform nanoscale particle size, good physicochemical stability, and adequate drug release behavior. More importantly, the glucagon-modified liposomes were enriched in the liver, which minimized the undesired bone and cardiovascular thyrotoxicity of T3. Compared to the control group, T3-loading glucagon-modified liposomes could effectively decrease body weight, reverse hepatic steatosis, and correct hyperlipidemia and hyperglycemia in ob/ob mice, without the undesired cardiovascular and bone thyrotoxicity.

CONCLUSION

These findings indicate that delivery of thyroid hormone by glucagon-modified liposomes may provide an effective strategy for anti-obesity therapy.

Monoclonal Antibodies, Gene Silencing and Gene Editing (CRISPR) Therapies for the Treatment of Hyperlipidemia-The Future Is Here

Hyperlipidemia is a significant risk factor for atherosclerotic cardiovascular disease. Undertreatment of elevated lipids persists despite existing therapies. Here, we provide an update on monoclonal antibodies, gene silencing therapies, and gene editing techniques for the management of hyperlipidemia. The current era of cutting-edge pharmaceuticals targeting low density lipoprotein cholesterol, PCSK9, lipoprotein (a), angiopoietin-like 3, and apolipoprotein C3 are reviewed. We outline what is known, studies in progress, and futuristic goals. This review of available and upcoming biotechnological lipid therapies is presented for clinicians managing patients with familial hyperlipidemia, statin intolerance, hypertriglyceridemia, or elevated lipoprotein (a) levels.
