Safety of Recombinant Zoster Vaccine in Rheumatology Patients.

OBJECTIVES: Recombinant zoster vaccine (RZV) is Food and Drug Administration approved for the prevention of herpes zoster (shingles) in adults 50 years old and older. Immunocompromised subjects were excluded from the pivotal vaccine trials. We studied the safety of this vaccine in our university-affiliated rheumatology practice. METHODS: This was a single-center, retrospective study focusing on subjects who received RZV during 2018. We collected the demographic data, any self-reported adverse events after vaccination, C-reactive protein, Routine Assessment of Patient Index Data 3 (RAPID3) scores for subjects with rheumatoid arthritis, and available RAPID3 scores for all study subjects before and after the vaccination. RESULTS: Comparision of C-reactive protein (n = 40), RAPID3 scores for subjects with rheumatoid arthritis (n = 16), and available RAPID3 scores for all subjects (n = 21) using the paired t test, did not show significant differences before and after the administration of RZV. A total of 6.4% of patients reported adverse events after vaccination. The adverse events were mild and did not lead to hospitalization, end organ damage, or change in treatment plan. CONCLUSIONS: The RZV was safe and well tolerated among our study population.

Dermatomyositis Developed After Exposure to Epstein-Barr Virus Infection and Antibiotics Use.

Dermatomyositis is an inflammatory disorder involving muscle and skin. Similar to many other autoimmune diseases, environmental factors appear to trigger the onset of disease in some cases. Many drugs have been reported to be associated with dermatomyositis, and rarely infections have been described as potential triggering agents. Here we are describing a case of dermatomyositis that developed after doxycycline and levofloxacin use, who also had recent Epstein-Barr virus infection. Dermatomyositis associated with doxycycline or levofloxacin use has not yet been described in the literature, while reports of dermatomyositis after Epstein-Barr virus infection have been rare and limited to juvenile dermatomyositis or in association with cancer. It is important for clinicians to be aware of this rare association so that the diagnosis and treatment can be exercised promptly.

Acute Liver and Renal Failure: A Rare Adverse Effect Exclusive to Intravenous form of Amiodarone.

Amiodarone is an antiarrhythmic drug which is highly effective against a wide spectrum of ventricular tachyarrhythmias making it irreplaceable in certain group of patients. We report an unusual case of acute liver and renal failure within 24 hours of initiation of intravenous (IV) amiodarone which resolved after stopping the medication. The mechanism of acute liver and renal toxicity is not clearly known but is believed to be secondary to amiodarone induced (relative) hypotension, idiosyncratic reaction to the drug, and toxicity of the vector that carries the medication, polysorbate-80. In this case review, we discuss the hyperacute drug toxicity caused by IV amiodarone being a distinctly different entity compared to the adverse effects shown by oral amiodarone and support the suggestion that oral amiodarone can be safely administered even in patients who manifest acute hepatitis with the IV form.
