RESUMEN
This study aimed to investigate the reporting rates of arthritis and arthralgia following the administration of four vaccines against SARS-CoV-2: Pfizer-BioNTech (Tozinameran), Moderna (CX-024414), AstraZeneca (Chadox1 NCOV-19), and Janssen (AD26.COV2.S) in 2021. We used data from the EudraVigilance database, specifically analyzing spontaneous reports of suspected adverse reactions (ADRs) from the European Union (EU)/European Economic Area (EEA) region. Age-group-specific reporting rates were calculated by dividing the number of arthralgia and arthritis reports per 1,000,000 vaccine doses administered per age group. Reporting rates were compared using a rate ratio among the four vaccines, using the AstraZeneca vaccine as a comparator. The AstraZeneca vaccine was associated with the highest rate of arthralgia across all age groups. Arthritis reporting rates were significantly lower, with the AstraZeneca vaccine having the highest rates in most age groups, except the 60-69 and 80+ groups, where the Janssen and Pfizer-BioNTech vaccines demonstrated higher reporting rates, respectively. The distribution of arthritis rates did not follow the arthralgia pattern, being higher in the 50-79 age group. This study is the first spontaneous reporting system analysis of arthritis reporting rates post-SARS-CoV-2 vaccination at a European level, revealing a higher reporting of suspected musculoskeletal adverse reactions after AstraZeneca vaccination. The findings underscore the need to consider commonly reported events like arthralgia in risk-benefit assessments prior to vaccination against SARS-CoV-2. Given the high prevalence of rheumatic and musculoskeletal diseases and vaccine hesitancy in this population, our results could influence vaccine choice and acceptance.

Systemic lupus erythematosus (SLE) is per se a disease characterized by suppressed immune response and thus susceptibility to various opportunistic infections. We describe the case of a 21-yearold woman who developed a rare zoonosis - hemotrophic mycoplasma infection in the initial stage of SLE, complicated with Nocardia asteroides pneumonia afterwards. Nocardia infection coincided with initiation of glucocorticoids and cyclophosphamide therapy for SLE. After the treatment she recovered completely. To our knowledge the only case of human hemoplasmosis (then referred to as eperythrozoonosis) in medical literature was the one described by a group of Croatian authors 22 years ago. No cases of a hemotrophic mycoplasma infection in a SLE patient have been published up to now.
