In this study, we aimed to examine the characteristics of early-onset PID and proposed a JAK-STATopathy subgroup based on their molecular defects. We reviewed 72 patients (<100days) retrospectively. These patients exhibited various immune-related phenotypes and received a definitive molecular diagnosis by next-generation sequencing (NGS)-based tests. We evaluated the PID-causing genes and clinical parameters. We assessed the genes that shared the JAK-STAT signalling pathway. We also examined the potential high risks related to the 180-day death rate. We identified PID disorders in 25 patients (34.72%, 25/72). The 180-day mortality was 26.39% (19/72). Early onset of disease (cut-off value of 3.5days of age) was associated with a high 180-day death rate ( =0.009). Combined immunodeficiency with associated or syndromic features comprisherapies. We analysed clinical factors that are predictive of a diagnosis of parotid abscess among patients with bacterial parotitis. This retrospective study included 64 hospitalised patients who were diagnosed with parotid abscess, or bacterial parotitis. Data on patient demographics, clinical characteristics, and clinical management were collected. Predictive factors for parotid abscess were evaluated using univariate and multivariate analysis. There were 25 patients with parotid abscess and 39 with bacterial parotitis. All patients presented with moderate-to-severe disease, required parenteral antibiotics, or had indicators for surgical drainage. Patient profiles and immune status were not significantly associated with parotid abscess. However, parameters that were significantly related to parotid abscess were subacute presentation (approximate 10.4 days) (p value=0.016), fluctuation (p value<0.001), and normal
