COVID-19 in Pregnant Women With Rheumatic Disease: Data From the COVID-19 Global Rheumatology Alliance.

OBJECTIVE: To describe coronavirus disease 2019 (COVID-19) and pregnancy outcomes in patients with rheumatic disease who were pregnant at the time of infection. METHODS: Since March 2020, the COVID-19 Global Rheumatology Alliance has collected cases of patients with rheumatic disease with COVID-19. We report details of pregnant women at the time of COVID-19 infection, including obstetric details separately ascertained from providers. RESULTS: We report on 39 patients, including 22 with obstetric detail available. The mean and median age was 33 years, range 24-45 years. Rheumatic disease diagnoses included rheumatoid arthritis (n = 9), systemic lupus erythematosus (n = 9), psoriatic arthritis/other inflammatory arthritides (n = 8), and antiphospholipid syndrome (n = 6). Most had a term birth (16/22), with 3 preterm births, 1 termination, and 1 miscarriage; 1 woman had yet to deliver at the time of report. One-quarter (n = 10/39) of pregnant women were hospitalized following COVID-19 diagnosis. Two of 39 (5%) required supplemental oxygen (both hospitalized); no patients died. The majority did not receive specific medication treatment for their COVID-19 (n = 32/39, 82%), and 7 patients received some combination of antimalarials, colchicine, anti-interleukin 1ß, azithromycin, glucocorticoids, and lopinavir/ritonavir. CONCLUSION: Women with rheumatic diseases who were pregnant at the time of COVID-19 had favorable outcomes. These data have limitations due to the small size and methodology; however, they provide cautious optimism for pregnancy outcomes for women with rheumatic disease particularly in comparison to the increased risk of poor outcomes that have been reported in other series of pregnant women with COVID-19.

Characteristics Associated with Acute-Phase Response following First Zoledronic Acid Infusion in Brazilian Population with Osteoporosis.

We aimed to evaluate characteristics associated with acute-phase response (APR) following first zoledronic acid infusion in a Brazilian cohort. This retrospective cohort study enrolled all adults with osteoporosis who underwent a first zoledronic acid infusion at our centre between June 2015 and June 2019. Clinical demographics (age, sex, diabetes, smoking, body mass index, and previous oral bisphosphonate use) and laboratory data (calcium, parathyroid hormone, renal function, and serum 25-hydroxyvitamin D and carboxy-terminal crosslinked telopeptide of type 1 collagen [CTX], both before and after infusion) were compared between patients with and without APR. We evaluated association magnitude between the presence of APR and clinical variables through logistic regression. This study enrolled 400 patients (women, 80%). APR was observed in 24.5% (n = 98) of patients. The mean symptom duration in days was 3.5 ± 2.8. Patients with APR were younger (67 ± 12 vs. 71 ± 11 years; p=0.001), used oral bisphosphonates less frequently (34% × 50%; p=0.005), and had greater baseline CTX (0.535 ng/mL [0.375, 0.697] × 0.430 [0.249, 0.681]; p=0.03) and ΔCTX (-69 [-76; -50] × -54 [-72; -23]; p=0.002) than those without APR. The other variables were similar between the groups. Only ΔCTX was associated (OR, 0.62; 95% CI 0.41-0.98) with APR after accounting for age and bisphosphonate use. APR occurred in 24.5% of the cohort. Younger age and absence of prior oral bisphosphonate use were associated with APR following first zoledronic acid infusion. APR was associated with ΔCTX (but no other variables) after adjusting for these factors.

HIV/AIDS and rheumatoid arthritis.

The acquired immunodeficiency syndrome (AIDS) is an infectious disease caused by the human immunodeficiency virus (HIV). It was first recognized in the United States in 1981, and the HIV/AIDS epidemic has since spread to affect all countries. The interface of HIV/AIDS with opportunistic infectious diseases is well characterized, but further research is required into the concurrence of other chronic diseases. The objective of this review was to identify possible interferences of HIV infection in the diagnosis and management of rheumatoid arthritis (RA). A review of the available evidence was conducted using the GRADE approach. Overall, the quality of evidence was low. Our main conclusions were: (1) the occurrence of rheumatoid-like arthritis in patients with HIV/AIDS is quite rare; therefore, it is not recommended that HIV infection be considered routinely as a differential diagnosis in this condition (C2); (2) HIV infection may lead to rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibody positivity, but usually at low titers (C1); (3) RA might cause false-positive HIV serology and ELISA seems to be a more specific test for HIV in patients with RA (C2); (4) RA and AIDS may coexist, even in cases of severe immunosuppression (C1); (5) RA emergence may seldom occur during or after immune reconstitution (C1); and (6) there is insufficient safety data to recommend use of specific disease-modifying antirheumatic drugs (DMARDs) in RA patients with HIV/AIDS. Therefore, these drugs should be used cautiously (C1).

Encefalopatia hereditária em bovinos no estado do Espírito Santo / Hereditary encephalopaty of cattle in Espírito Santo state, Brazil

Descrevem-se os aspectos epidemiológicos e clínico-necroscópicos de uma doença neurológica hereditária observada em bovinos no município de Ecoporanga, norte do Estado do Espírito Santo. Trata-se de enfermidade do sistema nervoso central verificada exclusivamente em fêmeas, filhas de touro reprodutor de 5 anos de idade da raça Nelore, oriundo do município de Curvelo, Minas Gerais, com vacas mestiças Nelore x Quianini; bezerros machos oriundos deste cruzamento não demonstraram quaisquer sinais relacionados à enfermidade. Os sinais clínicos, presentes ao nascimento ou detectáveis nas primeiras semanas de vida, caracterizam-se por ataxia, perda do equilíbrio, instabilidade, andar em círculos, posicionamento incorreto dos membros no animal em estação ou em marcha (afastamento e/ou desvio de membros da posição normal) e desvio lateral da coluna (eixo principal do corpo em diagonal). De animal para animal, há marcada variação na intensidade das manifestações clínicas. Os bovinos mais afetados morrem devido à incapacidade de se alimentar. O exame macroscópico evidenciou, em grau variável de intensidade, áreas de depressão assimétrica setorial, sobretudo nos lobos frontal e temporal do córtex telencefálico e no córtex cerebelar. Em adição observou-se atrofia de grupos musculares de membros correspondentes às porções defeituosas no sistema nervoso central. O estudo histológico inicial revelou que as áreas deprimidas devem-se à redução setorial de populações neuronais (provavelmente abiotrofia/atrofia) principalmente nos lobos cerebrais frontal e temporal e nas camadas granular e molecular do córtex cerebelar. Estudos morfométrico, imunohistoquímico e ultraestrutural estão sendo realizados e devem trazer mais informações sobre os aspectos microscópicos e patogenéticos. Os achados epidemiológicos indicam que a enfermidade está diretamente ligada ao cromossoma X, com penetrância completa e expressividade variável.

The epidemiological, clinical and pathological aspects of a neurological disease have been described in cattle in the Ecoporanga county, northeastern Espírito Santo, Brazil. This disease of the central nervous system occurred only in daughters of a 5-year-old Nelore bull crossed with Nelore x Quianini cows. The clinical signs, which were detectable immediately or in the first weeks after birth, are characterized by ataxia, instability, circling, abnormal position of the limbs when standing or walking (removal and/or deviation of members from the normal position) and lateral deviation of the vertebral column (main axis of the body in diagonal). The disease is expressed by variable widths in their clinical manifestations. Most affected animals died due to incapacity of milk or food intake. The macroscopic examination shows variable degree of asymmetric sectorial depressed areas of the frontal and temporal telencephalic cortex, and in the cortex of the cerebellum, as well as correspondent muscular (appendicular) atrophy. Histological examination revealed that the depressed areas are due to the sectorial reduction of neuronal populations (probably atrophy/abiotrophy), mainly in the frontal and temporal brain lobes, and in the molecular and granular layers of the cerebellar cortex. Morphometric, immunohistochemical and ultrastructural studies are underway and should provide more information about the microscopical and pathogenetic aspects. Epidemiological data indicate that the illness is directly linked to the chromosome X, with complete penetration and variable expressiveness.
