Rare case of homozygous ifnar1 deficiency in a samoan child with disseminated varicella after vaccination
Autosomal recessive interferon alpha/beta receptor 1 (IFNAR1) deficiency increases susceptibility to live-attenuated vaccines and wild-type viruses. Currently 16 cases, half with Polynesian ancestry have been reported since the discovery in 2019. Most cases present with severe MMR or yellow fever vaccine-related disease. Some cases report severe SARS-CoV-2, herpes simplex, and enterovirus. Varicella vaccine-related disease has been hypothesized but not previously reported.

A Broad Safety Assessment of the Recombinant Herpes Zoster Vaccine
Am J Epidemiol. 2022 Feb 12:kwac030. doi: 10.1093/aje/kwac030. Online ahead of print.ABSTRACTThe recombinant herpes zoster vaccine (RZV), approved as a 2-dose series in the U.S. in October 2017, has proven highly effective and generally safe. However, a small risk of Guillain-Barré syndrome (GBS) after vaccination was identified post-approval, and questions remain about other possible adverse events. This data-mining study assessed RZV safety in the U.S. using the self-controlled tree-temporal scan statistic, scanning data on thousands of diagnoses recorded during follow-up to detect any statistically unusual temporal clu...

Using the Self-Controlled Tree-Temporal Scan Statistic to Assess the Safety of Live Attenuated Herpes Zoster Vaccine.
Abstract The self-controlled tree-temporal scan statistic allows detection of potential vaccine- or drug-associated adverse events without pre-specifying the specific events or post-exposure risk intervals of concern. It thus opens a promising new avenue for safety studies. The method has been successfully used to evaluate the safety of two vaccines for adolescents and young adults, but its suitability to study vaccines for older adults had not been established. The current study applied the method to assess the safety of live attenuated herpes zoster vaccination during 2011-2017 in U.S. adults ≥ 60 years old, u...

A Systematic Review on Predisposition to Lymphoid (B and T cell) Neoplasias in Patients With Primary Immunodeficiencies and Immune Dysregulatory Disorders (Inborn Errors of Immunity)
Conclusions Though this is not a comprehensive summary of malignancies in PIDDs, or even lymphoproliferative disease in this area, this review summarizes the Medline-indexed published reports of B and T lymphomas in patients with PIDDs. This report highlights the diversity of malignant lymphoproliferative disorders in setting of PIDDs, and its associated challenges of diagnosis and treatment. The pathological classification and nomenclature for the lymphoid malignancies with variably reported and postulated underlying mechanisms were inconsistent and inadequate for many of these published reports. A wide range of treatmen...

Relationship between glucocorticoid dose and adverse events in systemic lupus erythematosus: data from a randomized clinical trial.
CONCLUSION: This study highlights the feasibility of post-hoc analyses of RCTs using the SHARE mechanism and demonstrates the association of GCs with various AEs. Contrary to expectations, there were also associations between lower cumulative GC dose and several other AEs. PMID: 28862513 [PubMed - as supplied by publisher]
