Polymyalgia Rheumatica Post-SARS-CoV-2 Infection

There is growing evidence that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to dysregulation of the immune system and, consequently, the development of autoimmune phenomena. Here, we describe the case of a 75-year-old woman with rheumatic manifestations characterized by intense musculoskeletal pain and stiffness in the neck and shoulders, with sudden onset and with the inability to raise her arms. The patient was admitted with severe pain located in the neck and shoulders. Previously, she had oropharyngeal pain, severe fatigue, and fever; a real-time polymerase chain reaction test for COVID-19 was positive. Two weeks later, the patient presented localized musculoskeletal pain in the neck and shoulders. Relevant laboratory results included an erythrocyte sedimentation rate of 46 mm/hr and a negative rheumatoid factor test; ultrasound findings with bilateral subacromial–subdeltoid bursitis were observed. A diagnosis of polymyalgia rheumatica (PMR) was initially made according to the EULAR/ACR provisional classification criteria for PMR; however, due to C-reactive protein negativity, the diagnosis was established based on symptoms. Management was with prednisone at the dose of 25 mg/day for 4 weeks and progressive reduction until prednisone suspension. The patient showed complete recovery at 6 months of follow-up. In this case, COVID-19 was implicated in the development of autoimmune and inflammatory rheumatic manifestations. PMR is a rare rheumatic condition that should be included in the wide range of rheumatologic manifestations expressed post-SARS-CoV-2 infection.

Autoreactive Antibodies Associated with Castleman Disease Triad

The Castleman triad has been described in a select few patients presenting with a retroperitoneal mass, mucocutaneous pemphigus vulgaris, and bronchiolitis obliterans. Here, we describe the Castleman triad in a 19-year-old male with unicentric hyaline vascular type Castleman disease (HV-CD). This patient presented with an array of positive antibodies, including anti-cyclic citrullinated peptide, anti-double-stranded DNA, and Sjogren’s IgG. Interestingly, the patient’s rheumatologic symptoms resolved after tumor resection, while his antibody profile remained relatively unchanged. HV-CD, with a triad presentation, was thought to be from a paraneoplastic syndrome secondary to an underlying lymphoproliferative disorder. The findings presented here identify multiple autoantibodies potentially contributing to this patient’s presentation with HV-CD.

Multiple Abscess Collections: Antibiotics or Steroids?

Aseptic abscess syndrome (AAS) is a medical rarity. The combination of multiple abscess collections in different organs, negative microbiological studies, and the association with an inflammatory bowel disease is highly suggestive for an AAS. The AAS is an acute neutrophilic dermatosis, so “generalized pyoderma gangraenosum” or “generalized bullous sweet syndrome” might be used synonymously. It is important to note that the diagnosis of an AAS can be made only after careful exclusion of an infectious disease. Of interest, despite the severity of the inflammation, patients with AAS are commonly hemodynamically stable. To date, no studies have investigated the optimal regimen, dose, and duration of therapy. Corticosteroids are the cornerstone of immunosuppression during the acute phase. After the induction phase, therapy might be switched to anakinra or infliximab.

Omeprazole Induced Rapid Drug Reaction with Eosinophilia, Systemic Symptoms, and Cross-Reactivity in Delayed-Type Hypersensitivity Associated with Proton-Pump Inhibitors: A Case Report and Literature Review

Background. Omeprazole, a proton pump inhibitor (PPI), is a widely used and generally safe agent for treating acid-related gastrointestinal conditions. However, drug reaction with eosinophilia and systemic symptoms (DRESSs) syndrome has been reported. Objectives. To report a case of omeprazole-induced rapid DRESS syndrome and to review the literature. Methods. Descriptive analysis of one new case and a case series from literature review. Results. We report a case of 82-year-old woman presenting with rapid-onset of DRESS syndrome. The condition was initially suspected to be caused by antibiotic, but the definite diagnosis was eventually omeprazole-induced DRESS syndrome as suggested by the enzyme-linked immune absorbent spot (ELISpot) assay along with the clinical picture. Previous literatures regarding cases of PPI-induced DRESS syndrome were pooled for descriptive analysis. Among 21 PPI cases pooled, esomeprazole was the most commonly implicated PPI (52.4%), followed by pantoprazole (19.1%), and omeprazole along with lansoprazole (both 14.3%). The issue of cross-reactivities amongst PPIs remains uncertain. Nonetheless, in situations in which a PPIs are deemed necessary, a prudent approach could be considering a switch to an alternative agent with distinct chemical structure. Conclusion. PPI is commonly used safely as an agent for acid-related gastrointestinal conditions. However, PPI-induced rapid DRESS syndrome can occur, particularly with prior exposure history. ELISpot is an in vitro test, useful in identifying the culprit agent in patients with delayed-type hypersensitivity reaction.

Novel BTK Mutation in Patient with Late Diagnosis of X-Linked Agammaglobulinemia

X-linked agammaglobulinemia (XLA) is a genetic disorder with mutation in Bruton’s tyrosine kinase (BTK). Defects in B cell development and immunoglobulin production lead to recurrent infections following loss of maternal IgG at 6 months of age. A 55-year-old male with a longstanding common variable immunodeficiency diagnosis on infusion therapy presented to the clinic with cutaneous T-cell lymphoma, which inspired overall repeat evaluation. Immunoglobulin levels and lymphocyte markers, family history, and genetic testing prompted a true diagnosis of XLA and novel mutation in the BTK gene. Disease-associated mutations have been noted in all five domains of BTK, with missense variants most commonly cited among the 100s of reported genetic alterations. The BTK protein is expressed in hematopoietic lineages and plasma cells, with the exception of T lymphocytes. Disruption in the protein function or absence of BTK halts normal B cell development at the pre-B transitional cell stage and induces premature apoptosis. We present the first reported case of a novel hemizygous BTK c.1492C > G mutation in a patient causing XLA.

Toxic Epidermal Necrolysis after COVID-19 mRNA-1237 Vaccination

This letter illustrates a case of toxic epidermal necrolysis (TEN) after COVID-19 mRNA-1273 vaccination, which corresponds with the existing published data and contributes detailed knowledge of TEN reaction after vaccination. Interestingly, the reaction started at the site of vaccination and the patient went on to tolerate a major excipient of the vaccine suggesting the reaction may be associated with the mRNA itself or is triggered by the immunostimulatory action of the vaccine.
