Review
Clinical significance of soluble interleukin-2 receptor measurement in immune-mediated diseases.
A soluble form of the interleukin-2 receptor (sIL-2R) is secreted upon T-cell activation. Increased blood levels of sIL-2R occur in a variety of immunological diseases. ⋯ In these, and in other immune-diseases, sIL-2R levels may be used as a biomarker to monitor/predict disease activity and treatment response. In this review, we will give a brief overview of the biology of the IL-2/IL-2R system and will subsequently discuss the clinical utility of sIL-2R measurement, especially in the context of haemophagocytic lymphohistiocytosis, sarcoidosis, rheumatoid arthritis, systemic lupus erythematosus, juvenile idiopathic arthritis, adult-onset Still's disease, ANCA-associated vasculitis, and IgG4-related disease.

Review Case Reports
HLH caused by an HSV-2 infection: a case report and review of the literature.
Haemophagocytic lymphohistiocytosis (HLH) is a rare hyperinflammatory condition that can be triggered by infections, malignancies, or auto-immune diseases. Here, we present a patient with rapidly progressive HLH triggered by a herpes simplex virus type 2 (HSV-2) primary infection. The patient was successfully treated with intravenous high-dose acyclovir, immunoglobulins, and dexamethasone. This is the first report of HSV-2-associated HLH in an immunocompetent adult patient.

Frailty screening in the emergency department may identify frail patients at risk for adverse outcomes. This study investigated if the Dutch Safety Management Program (VMS) screener predicts outcomes in older patients in the emergency department. ⋯ In this selected group of patients, higher VMS score was associated with 90-day mortality and falls. The low positive predictive value shows that the VMS screener is unsuitable for identifying high-risk patients in the ED. The high negative predictive value indicates that the screener can identify patients not at risk for adverse medical outcomes. This could be useful to determine which patients should undergo additional screening.

Case Reports
Spontaneous remission of unidentified Cushing's disease revealed by hair cortisol analysis.
Pituitary apoplexy is an infrequent but life-threatening complication of pituitary adenomas. When apoplexy occurs in a hormonally active adenoma, this may induce spontaneous remission of the clinical syndrome. ⋯ However, we describe a patient with Cushing's disease presenting with pituitary apoplexy, who was biochemically in remission at presentation. The diagnosis could be confirmed in retrospect using hair cortisol analysis, thereby enabling clinicians to adequately anticipate remission of Cushing's disease.
