Invasive fungal infections (IFI) were rarely observed in patients treated for CLL in the pre-BTK era. In this article, we describe two patients with CLL who developed an IFI during treatment with the BTK inhibitor ibrutinib. The atypical presentation and the serious course of this complication are described.The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a known cause of hyponatremia, caused by excessive ADH secretion which, in turn, leads to water retention. SIADH has been associated with multiple etiologies, one of which is traumatic brain injury (TBI). Most cases of SIADH after TBI describe a course in which hyponatraemia develops several days to weeks after the trauma and then resolves within a few weeks. We demonstrate a case of SIADH after TBI, which persisted several years after initial presentation, but eventually did resolve spontaneously after five years.This case report describes a patient who presented with a debilitating hepatitis C virus-related cryoglobulinaemic vasculitis who was treated with immunosuppression and direct-acting antivirals. After returning symptoms revealed a relapse of the hepatitis C virus infection, treatment with direct-acting antivirals was repeated. Subsequently, he achieved a sustained virological response and his vasculitis subsided.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 pa
