Thirty years ago, chronic conditions such as diabetes, heart disease, and obesity accounted for less than 45% of the global disease burden. Today, they are the leading causes of death and disability worldwide, having surpassed infectious diseases such as HIV/AIDS and malaria. ⋯ More recent research is continuing to define the contribution of other emerging factors to the risk of developing cardiovascular disease, particularly abdominal obesity that is associated with atherogenic dyslipidemia, insulin resistance, chronic inflammation, and prothrombotic state. All these factors constitute the global cardiometabolic risk that plays a significant role in development of cardiovascular disease.

Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment. The number of indications is increasing and antibodies targeting the CTLA-4 and PD-1/PD-L1 pathways are now also prescribed in adjuvant settings and for metastatic cancer. However, ICIs reactivate autoreactive immune cells as well as tumour-specific T cells, which lead to immune-related adverse events (irAEs) in around 70% of treated patients. ⋯ Some irAEs (especially myocarditis, pneumonitis, and encephalitis) are potentially fatal; in patients with highly suggestive clinical signs, treatment should be initiated before the diagnostic work-up has been completed. When confronted with an unexpected clinical sign, the physician must differentiate rapidly between an irAE, cancer progression, and another (unrelated) cause. The management of irAEs is based on the temporary or permanent discontinuation of the ICI and (for grade ≥ 2 events) the administration of steroids.

Algeria, like all emerging countries, has been going through a health transition over the past 30 years or so, characterized by a drop in mortality rates, an increase in life expectancy and a change in the causes of death in favor of chronic non-communicable diseases. In the past, the country mainly faced infectious diseases such as typhoid, cholera and malaria. The prevalence of the latter has been significantly reduced thanks to the many social health and vaccination programs undertaken by the health authorities. ⋯ According to the results of the latest national survey on the measurement of risk factors for non-communicable diseases (the Who StepWise approach), the prevalence of diabetes is close to 14.4% while the rate of obesity and overweight exceeds 50% of the population. High blood pressure has reached a prevalence rate of 23.6%. These diseases represent a real threat to our country's health, social and economic situation; they will lead to greater demands on health facilities and require more resources for intervention.

Cardiometabolic risk factors in Tunisia are growing fast. The main risk factor is metabolic syndrome which is a global health issue in both developing and developed countries. ⋯ Hypertension and diabetes are also additional risk factors predicting alarming mortality rates. We propose here a review of the determinants of metabolic syndrome in Tunisia and the overall cardiometabolic risk factors.
