RESUMO
BACKGROUND: This study sought to evaluate the main causes of hospitalization of patients with systemic lupus erythematosus (SLE) in a tertiary health center in Saudi Arabia. METHODS: A retrospective observational study was performed for all the SLE patients admitted to King Saud Medical City between 2016 and 2019. The primary reason for hospitalization was determined by the primary physician caring for the patient at the time of admission. RESULTS: Of the 98 hospitalizations for SLE, 49% of patients were admitted from the emergency department (ED) and 51% from the rheumatology clinic. The most common reason for hospitalization was lupus flare (68.4%) followed by infection (20.4%). The lupus flare patients commonly presented with musculoskeletal (MSK)symptoms (34.6%), renal manifestations (25.5%), and skin rash (24.5%), whereas patients admitted with infection were commonly diagnosed with community-acquired pneumonia (12.2%). Other hospitalization causes were obstetric complications, adverse drug reactions, and thrombosis. Intensive care unit (ICU) admission was necessary for 7% of patients due to acute respiratory distress syndrome (ARDS) and pulmonary hemorrhage (28.6%) or other reasons (14.1%), such as pleural effusion, cardiac tamponade, and thrombotic thrombocytopenic purpura (TTP). Conclusions: The two most common reasons for SLE hospitalization were lupus flare and infection. Lupus flare was mainly due to MSK, renal, and dermatologic manifestations. The most common infection leading to hospitalization was community-acquired pneumonia, and ICU admission was mainly due to ARDS and pulmonary hemorrhage.
RESUMO
OBJECTIVE: To study the effect of tocilizumab initiation on the lipid profile, in correlation to a composite of any cardiovascular events. METHODS: A retrospective cohort study, using data from the King Faisal Specialist Hospital & Research Centre database, from January 2014 to December 2019. Patients with rheumatoid arthritis or juvenile idiopathic arthritis who were ≥18 years old, initiated either on tocilizumab or other biologic treatment (anti-TNFs or Rituximab), were included, with a follow-up interval duration at a minimum of 6-12 months up to 3-5 years. Any patient with established cardiovascular disease or aged <18 were excluded. RESULTS: Only one cardiovascular mortality was reported in the tocilizumab group. Fifty percent of patients reached high cholesterol levels ≥ 5.2 mmol/L and LDL ≥ 3.37 mmol/L in the tocilizumab group at 36 months in a shorter time period compared to controls (60 months), P 0.001. There were no significant differences between groups for statin use (27% vs. 28%) However, there was a significantly higher mean dose of atorvastatin in the tocilizumab group compared to controls (20.6 mg vs. 16.6 mg, P 0.03). CONCLUSION: There was a lack of evidence of increased cardiovascular risk in correlation to hyperlipidemia secondary to tocilizumab treatment.
RESUMO
We report what we believe is the first case of posterior reversible encephalopathy syndrome (PRES) secondary to dialysis disequilibrium syndrome (DDS) in patients in whom all other possible causes of PRES were excluded and in whom a transient episode of tactile hallucination also occurred. We believe that this case of DDS was particularly severe, leading to PRES because of the late institution of dialysis therapy and the concomitant severe degree of metabolic acidosis on presentation.
