In this retrospective study, we described demographic information, reasons for admission, APACHE II severity scores, complications, mortality rate, causes of death and prognostic factors in 61 Thai patients with systemic lupus erythematosus (SLE) who were admitted to the medical intensive care unit (ICU) over a six-year period. The overall mortality rate during ICU hospitalization was 57% and the most common cause of death was infection, especially in the lower respiratory tract. The mean (SD) APACHE II score was 24.8 (10.8). SLE patients who had an APACHE II score of 20 or more were up to 65% of the patient population and had a significantly lower probability of survival based on Kaplan-Meier results (p = 0.004). The need for vasopressor therapy was significantly higher in patients who did not survive (OR = 6.98, 95% CI = 1.91-25.49). The patients who developed ventilator-associated pneumonia had a numerically higher mortality, which was not statistically significant (OR = 4.17, 95% CI = 0.91-19.03). The use of azathioprine as a steroid-sparing agent for SLE was associated with lower mortality rates (OR = 0.08, 95% CI = 0.01-0.58). Our findings emphasize that Thai SLE patients admitted to the medical ICU has a high mortality rate and early aggressive treatments are warranted.

The presence of renal involvement was associated with ON and the antimalarial use may have a protective effect for ON in Thai patients with SLE. The findings from this study further support the use of antimalarial drugs in SLE patients.

These recommendations will help Thai rheumatologists prescribe bDMARDs and tsDMARD more appropriately when treating RA patients.

Aim: To determine the relationship of apolipoprotein B (Apo-B) and arterial stiffness determined by brachialankle pulse wave velocity (baPWV) in systemic lupus erythematosus (SLE) subjects.Methods: Eighty-seven Thai SLE subjects with inactive disease activity were studied. Fasting blood was collected for creatinine, glucose, lipid profiles, Apo-B and Apo-A1. Pearson correlation and stepwise-linear regression were used for the analysis.Results: The mean age of the subjects was 36.69 AE 10.85 years; 6.90% of them had stage 3 or more severe chronic kidney disease, 49.40% took anti-hypertensive drugs and 4.60% had abnormal glucose metabolism. The mean value for baPWV was 1332 AE 274.12 cm/s. Thirty-six percent of the subjects had increased arterial stiffness with mean Apo-B levels of 1.05 AE 0.31 g/L compared to 0.94 AE 0.24 in normal arterial stiffness. There were correlations of baPWV with age, systolic blood pressure (BP), diastolic BP and creatinine clearance. Apo-B tended to be associated with baPWV (P = 0.06) whereas low-density lipoprotein cholesterol did not (P = 0.2). By multiple regression analysis, systolic BP, age and Apo-B were the significant predictors of baPWV.Conclusion: Apo-B was independently associated with arterial stiffness in SLE subjects.
