ABSTRACT

Chronic Lymphocytic Leukemia (CLL) is the most common type of leukemia in the US, representing approximately 1.1% of all new cancers diagnosed. Most patients with CLL can be monitored without treatment, and the indicated treatment options include a CD20 monoclonal antibody with or without bruton tyrosine kinase (BTK) inhibitors, phosphatidylinositol 3-kinase (PI3K) inhibitors, and B-cell lymphoma 2 (BCL2) antagonists. We review the case of a 77-year-old female with a long-standing history of CLL predominant lymphocytosis, transfusion -independent anemia, and thrombocytopenia. Patient responded to zanubrutinib after initial failure of idelalisib, rituximab, and acalabrutinib and venetoclax.

ABSTRACT

Iron deficiency is an independent risk factor for heart failure (HF) exacerbation. We aim to study the safety and efficacy of intravenous (IV) iron therapy in patients with HF with reduced ejection fraction (HFrEF). A literature search was conducted on MEDLINE (Embase and PubMed) using a systematic search strategy by PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) until October 2022. CRAN-R software (The R Foundation for Statistical Computing, Vienna, Austria) was used for statistical analysis. The quality assessment was performed using the Cochrane Risk of Bias and Newcastle-Ottawa Scale. We included 12 studies with a total of 4,376 patients (IV iron n = 1,985 [45.3%]; standard of care [SOC] n = 2,391 [54.6%]). The mean age was 70.37 ± 8.14 years and 71.75 ± 7.01 years in the IV iron and SOC groups, respectively. There was no significant difference in all-cause mortality and cardiovascular mortality (risk ratio [RR] 0.88, 95% confidence interval [CI] 0.74 to 1.04, p <0.15). However, HF readmissions were significantly lower in the IV iron group (RR 0.73, 95% CI 0.56 to 0.96, p = 0.026). Non-HF cardiac readmissions were not significantly different between the IV iron and SOC groups (RR 0.92, 95% CI 0.82 to 1.02, p = 0.12). In terms of safety, there was a similar rate of infection-related adverse events in both arms (RR 0.86, 95% CI 0.74 to 1, p = 0.05). IV iron therapy in patients with HFrEF is safe and shows a significant reduction in HF hospitalizations compared with SOC. There was no difference in the rate of infection-related adverse events. The changing landscape of HFrEF pharmacotherapy in the last decade may warrant a re-demonstration of the benefit of IV iron with current SOC. The cost-effectiveness of IV iron use also needs further study.

ABSTRACT

Immune thrombocytopenic purpura (ITP) is an acquired antibody or cell-mediated platelet damage or decreased platelet production. Steroids, IV immunoglobulins (IVIG), and Rho-anti-D antibodies are the commonly used initial treatments for ITP. However, many ITP patients either do not respond or do not maintain a response to initial therapy. Splenectomy, rituximab, and thrombomimetics are the commonly used second-line treatment. More treatment options include tyrosine kinases inhibitors (TKI), including spleen tyrosine kinase (Syk) and Bruton's tyrosine kinase (BTK) inhibitors. This review aims to assess the safety and efficacy of TKIs. Methods: Literature was searched on PubMed, Embase, WOS, and clinicaltrials.gov using keywords, "tyrosine kinase" and "idiopathic thrombocytopenic purpura". PRISMA guidelines were followed. Results: In total, 4 clinical trials were included with 255 adult patients with relapsed/refractory ITP. In all, 101 (39.6%) patients were treated with fostamatinib, 60 (23%) patients with rilzabrutinib, and 34 (13%) with HMPL-523. Patients treated with fostamatinib achieved a stable response (SR) and overall response (OR) in 18/101 (17.8%) and 43/101 (42.5%) of the patients, respectively, while SR and OR were achieved in 1/49 (2%) and 7/49 (14%) of the patients, respectively, in the placebo group. Patients treated with HMPL-523 (300 mg dose expansion) achieved an SR and OR in 5/20 (25%) and 11/20 (55%) of the patients, respectively, while SR and OR were achieved in 1/11 (9%) of the patients treated with the placebo. Patients treated with rilzabrutinib achieved an SR in 17/60 (28%) patients. Dizziness (1%), hypertension (2%), diarrhea (1%), and neutropenia (1%) were serious adverse events in fostamatinib patients. Rilzabrutinib or HMPL-523 patients did not require a dose reduction due to drug-related adverse effects. Conclusions: Rilzabrutinib, fostamatinib, and HMPL-523 were safe and effective in the treatment of relapsed/refractory ITP.

ABSTRACT

Antineutrophil cytoplasmic antibody (ANCA) is a systemic autoimmune disorder characterized by antibodies directed against small- and moderate-sized vessels. While there are few reported cases of autoimmune illnesses associated with influenza vaccination, two cases of de-novo anti-proteinase (PR3) ANCA-associated pauci immune glomerulonephritis are reported after the mRNA-1273 coronavirus disease 2019 (COVID-19) vaccine. Here, we report the third case of ANCA-associated glomerulonephritis after the mRNA-1273 COVID-19 vaccine. Our patient presented with acute kidney injury and sub-nephrotic proteinuria four days after receiving the second dose of the COVID vaccine. He was found to have elevated c-ANCA and anti-PR3 antibodies. Renal biopsy confirmed focal necrotizing and diffuse crescentic glomerulonephritis. He was diagnosed with pauci immune glomerulonephritis. The patient achieved remission 10 weeks after the diagnosis with successful treatment.
