RESUMEN
Patients with FLT3-mutated acute myeloid leukaemia (AML) that relapse or are refractory (R/R) to intensive induction have poor outcomes. Gilteritinib has recently become standard-of-care for patients with R/R FLT3-mutated AML. We investigated whether adding venetoclax to gilteritinib (gilt-ven) improves outcomes as compared with gilteritinib monotherapy. We included patients treated with gilteritinib (n = 19) and gilt-ven (n = 17) for R/R AML after intensive chemotherapy. Gilteritinib and gilt-ven groups did not differ in terms of mCRc rates (53% and 65%, p = 0.51) and realization of allogeneic haematopoietic stem-cell transplantation (HSCT, 47% and 35%, p = 0.5). Overall survival (OS) was comparable between groups, although a trend towards better OS was seen with gilt-ven (12-month OS 58.8% [95% CI 39.5%-87.6%]) versus gilteritinib (42.1% [95% CI 24.9%-71.3%] for gilteritinib). Early salvage with gilt-ven versus any other gilteritinib-based approach was associated with the best outcome (p = 0.031). Combination therapy was associated with increased haematological toxicity. In summary, gilt-ven did not improve remissions or HSCT-realization rates in patients with R/R FLT3-mutated AML as compared with gilteritinib and was associated with increased haematological toxicity. Although OS did not differ, a trend towards better survival was suggested with gilt-ven and a survival benefit was shown for gilt-ven approach when sequenced early for salvage.
RESUMEN
Monoclonal immunoglobulin deposition disease (MIDD) are a group of systemic diseases, characterized by deposition of monoclonal immunoglobulin predominantly in the kidney. In the absence of overt hematologic disease, MIDD are classified as a part of monoclonal gammopathy of renal significance. Patients with MIDD may present with a nephrotic syndrome and kidney function impairment. Treatment usually include anti-plasma cell therapy. Here we report a case of a 54-year-old female who presented with nephrotic syndrome related to light chain deposition disease of lambda type. Due to a complicated clinical course (including cardiac injury and thromboembolic stroke), plasma-cell targeted therapy was stopped. A few months later, the patient presented with severe acute kidney injury. Kidney biopsy revealed crescentic glomerulonephritis, and immunofluorescence staining was positive for lambda chain. Treatment with daratumumab was initiated resulting in stabilization of kidney function and partial nephrotic syndrome remission.
