Review: The application of corticosteroids in cryptococcal meningitis.

Cryptococcal meningitis (CM) is a serious disease with high morbidity and mortality. Although the patients who received corticosteroids were at high risk of having CM, corticosteroids also have been used as an adjunct to antifungal drugs for treating people with CM in some situations (such as immune reconstitution inflammatory syndrome, cerebral cyptococcoma, et al.). Here, we summarize the current knowledge on the application of the corticosteroids in CM, aiming to help clinicians to reasonably use corticosteroids in patients with CM.

Research progress of Cryptococcus gattii meningitis with different immune status / 中华神经科杂志

Cryptococcus gattii is a kind of Cryptococcus that infects the lungs and central nervous system through the inhalation of infectious particles such as spores or Cryptococcus yeast cells. The development of clinical disease of Cryptococcus gattii may be determined by the sex, immunity and genetics of the host factors, in which immune system factors play an important role in host injury. Their defects will have serious clinical consequences. Cryptococcus gattii mainly infects the population with normal immune, and the infection of immunosuppressed population is rare. The infection mechanism, molecular types, clinical characteristics, treatment and prognosis of Cryptococcus gattii meningitis were different between the two populations. This article reviews the main differences in different immune status with Cryptococcus gattii meningitis.

Postinfectious inflammatory response syndrome in patients with cryptococcal meningitis / 中华神经科杂志

Cryptococcal meningitis is a common fungal meningitis that may present with an abnormal immune response during effective antifungal therapy and is called immune reconstitution inflammatory syndrome in human immunodeficiency virus (HIV)-infected patients. Similar phenomenon can also be seen in non-HIV patients with normal immune function in the past. Paradoxical clinical and/or imaging deterioration occurs due to strong immune response during treatment, which is called post-infectious inflammatory response syndrome. At present, it has not attracted attention. This complication is an important cause of poor prognosis in non-HIV patients. Early identification and treatment of post-infectious inflammatory response syndrome is of great significance. This article will review its possible pathogenesis, clinical manifestations, imaging characteristics, risk prediction, diagnosis, treatment and prognosis.
