RESUMEN
We present two cases of Babesia-induced splenic injury at a single institution. In the late summer, two patients presented with left-sided abdominal pain radiating to the shoulder. They were both found to have hemolytic anemia, thrombocytopenia, and acute splenic infarction on imaging. Blood smears showed intracellular ring forms consistent with Babesia spp. and low parasitemia (<1%). Diagnosis was confirmed by PCR for Babesia microti. Both patients improved with azithromycin and atovaquone, without blood products or surgical intervention. Several weeks following treatment, repeat blood smears revealed no parasites. Splenic infarct and hemorrhage have been previously reported as rare complications of babesiosis. However, given the steady rise in Babesia microti cases in the USA, even these rare complications will become more prevalent. We review both the diagnosis and management of Babesia-induced splenic complications, which can be challenging in patients with low-level parasitemia. Clinicians should consider babesiosis as a cause of atraumatic splenic injury.

OBJECTIVE: Increases in global temperatures and extreme weather events associated with climate change have complex yet poorly understood detrimental impacts on human health. We reviewed the current published literature on climate change-related effects and rheumatic conditions. METHODS: To summarize our current understanding of the likely effects of climate change, including increased air pollution, on rheumatic disease, we searched the published, peer-reviewed English-language literature from January 2000 to December 2022. Articles were reviewed by a team of rheumatologists and clinical and translational science researchers. Systematic review articles were not included but informed additional literature searches. RESULTS: After extensive examination and adjudication, 88 articles met inclusion criteria and were selected for review. Much of the epidemiologic investigations assessed associations between air pollution and increased risk of development of rheumatoid arthritis, anti-citrullinated protein antibodies, flares of gout, and hospitalizations for systemic lupus erythematosus. Increased heat vulnerability was associated with higher odds of recurrent hospitalizations across rheumatic conditions. Mechanisms for observed associations are poorly understood but could include the effects of epigenetic changes, oxidative stress, and inflammatory cytokines. Studies had limitations, including restricted geography and populations studied without focus on historically marginalized communities at highest risk for adverse effects from pollution and climate change, the relative lack of mechanistic evaluations, and most with only indirect links to climate change. CONCLUSION: To date, the published literature lacks studies that directly examine effects of climate change on rheumatic diseases. Collaborative translational and epidemiologic research is needed to enhance our understanding and awareness in this area.

RESUMEN
Infection with SARS-CoV-2 (COVID-19) virus is characterized by an acute respiratory viral illness, often accompanied by extrapulmonary manifestations. Musculoskeletal symptoms such as myalgias and arthralgias are observed in 60 - 70% of cases. Inflammatory arthritis associated with SARS-CoV-2 infection has been reported in the literature, however, nearly all such cases describe a post-viral or reactive phenomenon occurring a few weeks following the infection. We report a unique case of de novo arthritis at the onset of a confirmed COVID-19 infection in a 55-year-old woman. Magnetic resonance imaging demonstrated synovial enhancement consistent with synovitis. Her disease was deemed refractory after failing several immunosuppressive agents. Lastly, we compare our patient's clinical presentation with two other similar cases to understand the natural history of this emerging syndrome.
