Henoch-Schönlein purpura is a systemic vasculitis of the small vessels characterized by perivascular leucocyte infiltrates. It is an immunoglobulin A-related immune complex-mediated disease involving the skin, the joints and the gastrointestinal system. Renal disease may sometimes be associated to these clinical manifestations. ⋯ Recent publications of pediatric and adult series show that the chronic renal failure may progress, sometimes more than ten years after the initial flare. Treatment is usually supportive. The benefit of more specific treatments (corticosteroids or immunosuppressive drugs) in severe visceral forms (usually abdominal or kidney) has not yet been established.

We present the recent therapeutic advances in the cystic fibrosis care. It concerns improvements in symptomatic treatment with the development of dry powder inhaled antibiotics that improved quality of life, and innovative treatments namely the modulators of the cystic fibrosis transmembrane protein conductance regulator (CFTR), molecules which act specifically at the level of the defective mechanisms implied in the disease. The life expectancy of cystic fibrosis patients born after 2000, is estimated now to be about 50 years. ⋯ We presently have numerous symptomatic treatments for the cystic fibrosis care. The development of CFTR modulators, today available to a restricted number of patients treated with ivacaftor represents a very promising therapeutic avenue. It will represent probably the first step to a personalized treatment according to CFTR genotype.

Infections are an important cause of cancer in the world, representing approximately 16% of the neoplasia. Ten infectious agents have been classified as carcinogens of group I. Four of these pathogens (Helicobacter pylori, hepatitis B and C viruses, and some human papillomavirus) are responsible for 95% of cases of infection-related cancers. ⋯ This allowed to consider prevention of certain cancers, for example with a prophylactic vaccine strategy. Advances were also made in the curative field. However, efforts remain to be done to discover new infectious causes of cancer and refine the understanding of the mechanisms of carcinogenesis, for a better targeting of anticancer therapeutics.

Behçet's disease (BD) is a systemic large-vessel vasculitis characterized by a wide clinical spectrum including recurrent oral and genital ulcerations, uveitis, vascular, neurological, articular, and gastrointestinal manifestations. Therapeutic management of BD depends on the clinical presentation and organ involved. Although colchicine, non-steroidal anti-inflammatory agents and topical treatments with corticosteroids are often sufficient for mucocutaneous and joint involvement, a more aggressive approach with immunosuppressive agents is warranted for severe manifestations such as posterior uveitis, retinal vasculitis, vascular, neurological and gastrointestinal involvement. ⋯ Recent improvements in the understanding of the pathogenic mechanisms have led to the identification of potential targets and future therapies for BD. In contrast to current non-specific immunosuppressive agents, the emergence of immunomodulatory drugs provides the possibility of interfering with specific pathogenic pathways. Novel targeted immunosuppressive therapies might be used in the future for BD.

Recent advances in neuroimaging have simplified the diagnostic criteria of multiple sclerosis. Indeed, the diagnosis of multiple sclerosis could be obtained during the first bout of disease flare, very early in the disease course. ⋯ At the same time, major therapeutic advances have been obtained and new drugs that are well tolerated and more effective, despite the possible rare but potentially severe side effects are been developed. This article reviews the modern diagnostic and therapeutic strategies in multiple sclerosis in accordance with the recent obtained advances.
