This article presents a clinical case of ocular thrombotic microangiopathy of mixed origin (antiphospholipid syndrome, malignant arterial hypertension, multigenic thrombophilia). Multimodal imaging of the fundus provides a detailed assessment of its structures. Pathological changes in the choroid, the "retinal pigment epithelium - Bruch's membrane" complex, and the neurosensory retina, identified using fundus photography, short-wavelength autofluorescence, optical coherence tomography (OCT), and OCT angiography, are described as nonspecific in nature. Given the verification of renal thrombotic microangiopathy by nephrobiopsy in this clinical case, the likely pathogenic mechanism underlying the observed chorioretinopathy manifestations is chronic ocular thrombotic microangiopathy.

Introduction: Tacrolimus-induced thrombotic microangiopathy (TMA) causing acute kidney injury (AKI) without systemic features is a rare entity, particularly after non-renal solid organ transplantation.
Case Report: We describe the case of a patient with AKI after combined heart and lung transplantation. Renal biopsy revealed acute thrombotic microangiopathy which ultimately prompted initiation of eculizumab, a monoclonal antibody targeted against complement C5, with subsequent recovery in renal function.

Plasma exchange (PE) outcomes in patients with trigger-associated thrombotic microangiopathy (TMA) have not been comprehensively reviewed. Embase and MEDLINE® were searched on 03/14/2022 for English language articles published after 2007, alongside a congress materials search (2019-2022; PROSPERO: CRD42022325170). Studies with patients with trigger-associated TMA (excluding thrombotic thrombocytopenic purpura, 'typical' hemolytic uremic syndrome caused by Shiga toxin-producing Escherichia coli, post-partum TMA, and TMAs with known genetic cause) who received PE or plasma infusion (PI) and reported treatment response (including measures), safety, patient-/caregiver-reported outcomes, or economic burden data were examined.

Background Aims: With novel therapies improving prognosis, the complications of multiple myeloma after multi-line treatment, particularly myelosuppression, have become a crucial determinant of long-term outcomes. Non-myeloablative allogeneic hematopoietic stem cell transplantation is a feasible option, but the transplant-related mortality rate remains high. Our study presents a relapsed/refractory multiple myeloma patient with a 9-year disease history.

Hemolytic-uremic syndrome (HUS) is a systemic complication of an infection with Shiga toxin (Stx)-producing enterohemorrhagic , primarily leading to acute kidney injury (AKI) and microangiopathic hemolytic anemia. Although free heme has been found to aggravate renal damage in hemolytic diseases, the relevance of the heme-degrading enzyme heme oxygenase-1 (HO-1, encoded by ) in HUS has not yet been investigated. We hypothesized that HO-1 also important in acute phase responses in damage and inflammation, contributes to renal pathogenesis in HUS.
