Objective:To explore the clinical characteristics and influencing factors of myocarditis induced by immune checkpoint inhibitors (ICIs).Methods:Using programmed death receptor-1 (PD-1), nivolumab, pembrolizumab, programmed cell death receptor ligand-1 (PD-L1), atezolizumab, durvalumab, avelumab, cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), ipilimumab, tremelimumab as keywords respectively, we combined these words with myocarditis or the corresponding Chinese to search.Results:A total of 49 articles were reported, including 64 patients. Nivolumab was the most reported, followed by pembrolizumab and ipilimumab. The average age was (65.47±13.24)years, mainly elderly patients; 37 cases (57.81%) were male; the overall mortality rate was 31.25%(20/64). The clinical symptoms were diverse and nonspecific, with dyspnea being the most common (39/64, 60.94%). Heart biomarkers were elevated in 94.64%(53/56) of the patients. 35 patients (54.69%, 35/64) developed myocarditis after 1-2 doses and 17 patients died. 60 patients received steroids as initial treatment, and immunosuppressive therapies such as infliximab, intravenous immunoglobulin, antithymic globulin, and/or plasmapheresis were used in 25 patients, symptoms improved in 17 cases (68.00%).Conclusions:ICIs can cause myocarditis, with high mortality, and should be closely monitored and timely treatment. Steroids can be used as initial first-line therapy and immunosuppressants and/or plasmapheresis may improve clinical symptoms and survival rate.

Objective:To analyze the clinical symptoms and laboratory characteristics of patients with brucellosis combined with osteoarthritis.Methods:A retrospective analysis was conducted on the medical records of 168 patients with brucellosis who were hospitalized at the Jining Public Health Medical Center, Shandong Province from January 2021 to December 2022. Based on the imaging examination results, they were divided into combined osteoarthritis group and non combined osteoarthritis group. The demographic characteristics, clinical symptoms, and laboratory test results of the two groups of patients were compared and analyzed.Results:Among 168 patients with brucellosis, there were 83 patients with concurrent osteoarthritis, 85 patients without concurrent osteoarthritis, the males and females ratio was 2.73 ∶ 1.00 (123 ∶ 45), and the age was 56 (46, 64) years old. The median age of patients in combined osteoarthritis group was higher than that of patients in non combined osteoarthritis group (58 years vs 53 years, Z = - 2.89, P = 0.004). In clinical symptoms, the incidence of back pain, fatigue, and joint muscle pain in patients of combined osteoarthritis group was significantly higher than that in the non combined osteoarthritis group [75.9% (63/83) vs 56.5% (48/85), 30.1% (25/83) vs 15.3% (13/85), 47.0% (39/83) vs 17.6% (15/85), χ 2 = 7.07, 5.27, 16.58, P < 0.05]. In laboratory tests, the erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (hs-CRP) levels in patients of combined osteoarthritis group were higher than those in the non combined osteoarthritis group [27.0 (17.0, 34.0) mm/h vs 21.0 (10.5, 34.0) mm/h, 22.7 (14.3, 43.4) mg/L vs 17.9 (10.8, 34.2) mg/L, Z = - 2.51, - 2.00, P < 0.05]. Among patients with combined osteoarthritis, combined spondylitis accounted for the highest proportion (55.4%, 46/83), followed by peripheral arthritis (51.8%, 43/83). Conclusion:Osteoarthritis is a common complication of brucellosis, and patients of brucellosis with concurrent osteoarthritis have clinical features such as lower back pain, fatigue, and joint muscle pain, with significantly elevated of ESR and hs-CRP level.

Objective:To explore the mechanism of lysosomal membrane permeabilization(LMP)inuranyl acetate-induced death of human kidney proximal tubular epithelial HK-2 cells.Methods:HK-2 cells were exposed to uranyl acetate at concentrations of 100, 300 and 600 μmol/L for 24 h, then in tracellular reactive oxygen species (ROS)and mitochondrial superoxide were measured by DCFH-DA and MitoSOX probe, respectively. HK-2 cells were divided into four groups: blank control group, NAC or CA-074 Me group, uranyl acetate exposure group and uranyl acetate exposure plus NAC or CA-074 Me group. Two-color immune of luorescence staining was used to detect the co-localization of galectin-1 and lysosomal associated membrane protein-1 (LAMP-1) to measure the extent of LMP, and to detect the non- co-localization of cathepsin B and LAMP-1 to reflect the release of cathepsin B in lysosomes. Calcein-AM/PI double staining method was used to detect cell death. One-color immune of luorescence staining of cleaved-caspase-3 expression was used to detect apoptosis. Results:Intracellular ROS and mitochondrial superoxide levels were significantly increased in HK-2 cells after exposure with 100, 300 and 600 μmol/L uranyl acetate for 24 h, about 1.1-2.5 times or 4.0-28 times, respectively( tROS=17.98, 11.84, 11.75, P< 0.05; tmitochondrial superoxide=6.14, 16.02, 13.06, P< 0.05), and they also increased with uranyl acetate concentrations ( tROS=10.10, 10.37, 5.59, P< 0.05; tmitochondrial superoxide=21.50, 15.16, 5.93, P< 0.05). The percentage of co-localization of galectin-1 and LAMP-1 and the percentage of non- co-localization of cathepsin B and LAMP-1 were markedly increased in HK-2 cells after exposure with 600 μmol/L uranyl acetate for 24 h, 5.4-6.7 times or 1.5-2.1 times, respectively ( tGalectin-1=15.85, 12.70, P< 0.05; tCathepsin B=5.95, 6.69, P< 0.05), but these increases were inhibited by NAC ( tGalectin-1=4.74, P<0.05; tCathepsin B=4.51, P< 0.05). Moreover, the cell death rate and the cleaved-caspase-3 expression level were also significantly increased in HK-2 cells after exposure with 600 μmol/L uranyl acetate for 24 h, about 28-47 times or 2.4-6.0 times, respectively( tPI=30.40, 10.34, P<0.05; tCleaved-caspase-3=18.49, 9.52, P<0.05), and these increases were obviously diminished by CA-074 Me ( tPI= 6.76, P<0.05; tCleaved-caspase-3=13.47, P<0.05). Conclusions:Exposure to uranyl acetate induces a burst of intracellular ROSthat leads to LMP and consequently causes leakage of cathepsin B from lysosomes to cytoplasm, in turn triggering the lysosomal-dependent cell death and mitochondrial-regulated apoptosis of HK-2 cells.
