Objective: We aimed to develop a useful nomogram for early identification of Kawasaki disease (KD) children at a high risk of intravenous immunoglobulin (IVIG) resistance and coronary artery lesion (CAL) complications to improve KD management.
Methods: Clinical data from 400 patients treated at our hospital between January 1, 2016, and December 31, 2023, were collected. Lasso regression was utilized to screen risk factors for IVIG resistance and CAL involvement. Subsequently, a Logistic regression model incorporating parameters screened by Lasso regression was established and visualized as a nomogram. The discrimination, calibration, clinical applicability, and universality of the model were evaluated using receiver operating characteristic (ROC) curves, calibration curves, decision curve analysis (DCA), and internal validation.
Results: NEU%, HDL-C, and MHR were identified as predictors of IVIG resistance by Lasso regression, with C-index of the Logistic model being 0.886 for the training set and 0.855 for the validation set. For predicting CAL development, sex, fever date before the first IVIG administration, KD type, and the level of HDL-C and MHR were the optimal variables, yielding C-index of 0.915 and 0.866 for the training and validation set, respectively. Calibration curves for both validation sets performed well, indicating strong predictive abilities of the models.
Conclusions: We established a nomogram for predicting IVIG resistance that incorporates NEU%, HDL-C, and MHR and a second nomogram for CAL complications incorporating sex, fever date, KD type, and the level of HDL-C and MHR in KD patients, based on the Lasso-Logistic regression model. These nomograms were of guiding significance for screening KD children at high risk of developing IVIG resistance and CAL complications, thereby improving prognosis. Key Points • Two nomograms were established to predict IVIG resistance and CAL complications in KD patients, based on the Lasso-Logistic regression model.

Several studies explored the associations of pre-albumin (PA)/albumin (ALB) and ALB-combined indicators (prognostic nutrition index [PNI], albumin-to-globulin ratio [AGR], bilirubin-to-albumin [BAR], and C-reactive protein/albumin ratio [CAR]) with intravenous immunoglobulin (IVIG) resistance and coronary artery lesions (CALs) in Kawasaki disease (KD) patients. However, the results were controversial. A meta-analysis was conducted to reconfirm their associations and predictive performance.

While intravenous immunoglobulin (IVIG) is effective in reducing immunologic inflammation, 10-15% of patients do not respond to initial therapy, and some show resistance even after two consecutive treatments. Predicting which patients will not respond to these two IVIG treatments is crucial for guiding treatment strategies and improving outcomes.

Pemphigus vulgaris is a severe and often therapy-resistant bullous autoimmune disease. Standard therapy with steroids often administered together with another immunosuppressant does not respond in all patients or may not be a good therapeutic option in patients with severe underlying diseases. Intravenous immunoglobulins (IVIgs) represent a treatment alternative, often showing a rapid response which allows one to reduce concomitant immunosuppression.

Background: Evans syndrome is a rare disorder characterized by the simultaneous or sequential combination of autoimmune hemolytic anemia and immunological thrombocytopenia, together with a positive direct antiglobulin test. This syndrome, which can be primary or secondary, is a rare initial manifestation of autoimmune diseases, notably systemic lupus erythematosus, with 1.7-2.
