Successful radical surgery for lymph node metastasis in a patient with hepatocellular carcinoma following atezolizumab plus bevacizumab combination therapy: a case report and literature review.

A woman in her early 80 s was followed up in our hospital for chronic hepatitis C after viral eradication. We detected rapid-growing lymph node metastasis of hepatocellular carcinoma (HCC) after treatment with transcatheter arterial chemoembolization and/or radiofrequency ablation. We found that the metastasis was operable, but the size and location of the metastasis obliged the patient to receive pancreatoduodenectomy, which was too invasive. Then we initiated systemic chemotherapy to perform radical minimally invasive surgery. We treated the patient with 3 weekly cycles of atezolizumab 1200 mg plus bevacizumab 15 mg/kg. The patient tolerated the treatment well, and treatment-emergent adverse events included deterioration of hypertension and increased uric protein. After a total of 4 cycles of therapy, abdominal computed tomography findings showed that the metastasis evidently decreased, and a complete response was achieved based on the Revised Response Evaluation Criteria in Solid Tumors (RECIST) guidelines (version 1.1). Seventeen days later, the metastasis was dissected. Subsequently, we confirmed that there was no pathological metastatic lesion in the resected lymph node. Our case is the first report of successful application of the radical therapy to lymph node metastasis of HCC via combination therapy with atezolizumab/bevacizumab.

Disseminated Lomentospora prolificans infection that could have been predicted: A case report.

Lomentospora prolificans is a rare, filamentous fungus, that causes a disseminated infection in immunocompromised individuals. Disseminated infections caused by the fungus are difficult to diagnose early. It is resistant to multiple antifungal agents and has a high mortality rate. We encountered a case in which the involvement of this fungus was indicated by a history of antifungal prophylaxis and an elevated serum 1,3-beta-D-glucan (BDG) level. A 76-year-old female with myelodysplastic syndrome that developed into overt leukemia was administered oral posaconazole as antifungal prophylaxis. She was admitted to the hospital to determine the cause of her fever, where no new abnormalities other than an elevated serum BDG level were observed. Unfortunately, the patient died due to acute respiratory failure on the same day of admission. The day after her death, L. prolificans was detected in a blood culture taken upon her admission. L. prolificans should be suspected based on the history of antifungal prophylaxis and an elevated serum BDG level, as these are risk factors for infection by this pathogen. Blood cultures are useful to provide a diagnosis. If treated early, before it is detected in culture, the mortality rate can be decreased.

Allergic bronchopulmonary mycosis in Schizophyllum commune with positive Aspergillus-specific IgE antibodies: A case report.

Schizophyllum commune is the third most common causative fungus of allergic bronchopulmonary mycosis(ABPM). Two-thirds of ABPM caused by S. commune can be positive for Aspergillus fumigatus-specific IgE, which can be difficult to diagnose. Our patient presented to our hospital with wet cough for 3 months and chest pain for 3 days. Blood tests showed IgE 1522 IU/mL, eosinophils 688/mm3, A. fumigatus -specific IgE 2.24 UA/mL, and chest computed tomography showed high-attenuation mucus. Bronchoscopy showed mucus plugs and speculum examination showed filamentous fungi, but various culture tests did not detect A. fumigatus, Asp f 1-specific IgE was negative, and S. commune was detected in the culture of bronchial washing. Since he was positive for S. commune-specific IgE and IgG, he diagnosed ABPM caused by S. commune. These findings demonstrate the importance of identifying the causative fungus in ABPM by detailed examination.

Insights into Aspergillus fumigatus Colonization in Cystic Fibrosis and Cross-Transmission between Patients and Hospital Environments.

BACKGROUND: Approximately 60% of individuals with cystic fibrosis (CF) are affected by Aspergillus fumigatus infection. This condition is correlated with a decline in lung function and is identified as an independent risk factor contributing to hospital admissions among CF patients. This study investigates the dynamic interplay of A. fumigatus within the context of CF patients, tracing its evolution over time, with a specific emphasis on colonization dynamics. METHODS: An analysis was conducted on 83 sequential A. fumigatus isolates derived from sputum samples of six patients receiving care at a renowned CF hospital in Brazil. Employing microsatellite genotyping techniques, alongside an investigation into cyp51A gene mutations, this research sheds light on the genetic variations, colonization, and resistance of A. fumigatus within the CF respiratory environment. RESULTS: Our research findings indicate that CF patients can harbor A. fumigatus strains from the same clonal complexes for prolonged periods. Additionally, we identified that clinical isolates have the potential to spread among patients in the same healthcare facility, evidencing hospital contamination. Two patients who underwent long-term Itraconazole treatment did not show phenotypic resistance. However, one of these patients exhibited mutations in the cyp51A gene, indicating the need to monitor resistance to azoles in these patients colonized for long periods by A. fumigatus. We also observed co-colonization or co-infection involving multiple genotypes in all patients over time. CONCLUSION: This comprehensive examination offers valuable insights into the pathogenesis of A. fumigatus infections in CF patients, potentially shaping future therapeutic strategies and management approaches. This enhanced understanding contributes to our knowledge of A. fumigatus impact on disease progression in individuals with cystic fibrosis. Additionally, the study provides evidence of cross-contamination among patients undergoing treatment at the same hospital.

Neuroradiological, genetic and clinical characteristics of histone H3 K27-mutant diffuse midline gliomas in the Kansai Molecular Diagnosis Network for CNS Tumors (Kansai Network): multicenter retrospective cohort.

This study aims to elucidate the clinical and molecular characteristics, treatment outcomes and prognostic factors of patients with histone H3 K27-mutant diffuse midline glioma. We retrospectively analyzed 93 patients with diffuse midline glioma (47 thalamus, 24 brainstem, 12 spinal cord and 10 other midline locations) treated at 24 affiliated hospitals in the Kansai Molecular Diagnosis Network for CNS Tumors. Considering the term "midline" areas, which had been confused in previous reports, we classified four midline locations based on previous reports and anatomical findings. Clinical and molecular characteristics of the study cohort included: age 4-78 years, female sex (41%), lower-grade histology (56%), preoperative Karnofsky performance status (KPS) scores ≥ 80 (49%), resection (36%), adjuvant radiation plus chemotherapy (83%), temozolomide therapy (76%), bevacizumab therapy (42%), HIST1H3B p.K27M mutation (2%), TERT promoter mutation (3%), MGMT promoter methylation (9%), BRAF p.V600E mutation (1%), FGFR1 mutation (14%) and EGFR mutation (3%). Median progression-free and overall survival time was 9.9 ± 1.0 (7.9-11.9, 95% CI) and 16.6 ± 1.4 (13.9-19.3, 95% CI) months, respectively. Female sex, preoperative KPS score ≥ 80, adjuvant radiation + temozolomide and radiation ≥ 50 Gy were associated with favorable prognosis. Female sex and preoperative KPS score ≥ 80 were identified as independent good prognostic factors. This study demonstrated the current state of clinical practice for patients with diffuse midline glioma and molecular analyses of diffuse midline glioma in real-world settings. Further investigation in a larger population would contribute to better understanding of the pathology of diffuse midline glioma.

Effectiveness of isavuconazole in invasive cerebral aspergillosis during hematopoietic stem cell transplantation in a pediatric patient with myelodysplastic syndrome: A case report.

Pediatric myelodysplasia syndrome is often characterized by hypoplastic bone marrow morphology and predisposition to infection. Invasive aspergillosis during hematopoietic stem cell transplantation poses a significant threat and often requires voriconazole (VRCZ) therapy. However, difficulties in achieving appropriate VRCZ blood levels due to drug interactions have prompted the exploration of alternative treatments, such as isavuconazole (ISCZ). We present the case of a 4-year-old boy with myelodysplasia syndrome who developed multiple abscesses, including a brain abscess caused by Aspergillus fumigatus, and was successfully treated with ISCZ. Despite initial treatment with liposomal amphotericin B and VRCZ, the patient's condition deteriorated. Transitioning to ISCZ treatment resulted in significant clinical improvement, resolution of the abscesses, and reduced antigen levels. Although ISCZ induced hepatic enzyme elevation, supportive care improved without discontinuation of treatment. This case highlights the potential of ISCZ in cases of pediatric invasive aspergillosis where traditional therapies fail, underscoring the need for further research and formulation development to optimize its use in this population. As more cases accumulate, ISCZ may become a promising option for treating severe invasive aspergillosis in pediatric patients undergoing hematopoietic stem cell transplantation.

Advantages of laparoscopic segmentectomy of the liver using ICG fluorescent navigation by the negative staining method: A comparison with open procedure.

Aim: Laparoscopic segmentectomy (LS) using indocyanine green (ICG) fluorescence navigation with negative staining method has potential for performing accurate and safe anatomical excision. This study aimed to evaluate the significance of LS using ICG fluorescence navigation compared with open segmentectomy (OS). Methods: Eighty-seven patients who underwent anatomical segmentectomies were evaluated for OS (n = 44) and LS (n = 43). The Glissonean pedicle approach was performed using either extra- or intrahepatic method, depending on the location of segment in LS. After clamping pedicle, negative staining method was performed. Liver transection was done along intersegmental plane visualizing by overlay mode of ICG camera. Surgical outcomes were compared between two groups. Correlation between predicted resecting liver volume (PRLV) calculated using volumetry and actual resected liver volume (ARLV) was assessed in two groups. Results: Patients who underwent LS showed better outcomes in operative time, blood loss, and length of hospital stay. There were significantly fewer Grade II and Grade III or higher postoperative complications in LS group. Both values of AST (p < 0.001) and ALT (p < 0.001) on postoperative day 1 were significantly lower in LS group than in OS group. PRLV and ARLV were more strongly correlated in LS (r = 0.896) than in OS (r = 0.773). The difference between PRLV and ARLV was significantly lower in LS group than in OS group (p = 0.022), and this trend was particularly noticeable in posterosuperior segment (p = 0.008) than in anterolateral segment (p = 0.811). Conclusion: LS using ICG navigation allows precise resection and may contribute to safer short-term outcomes than OS, particularly in posterosuperior segment.

Comparison of galactomannan lateral flow assay and enzyme immunoassay to identify Aspergillus spp. in bronchoalveolar lavage fluid.

Aspergillus species can colonize and infect immunocompetent and immunocompromised hosts. Conventional fungal identification depends on microscopic analysis and microorganism medium growth. Other diagnostic methods, non-growth dependent, to invasive fungal infections, are the biomarkers that detect circulating polysaccharides, for example, 1-3-ß-d-Glucan and galactomannan. Both are polysaccharides present on the external layer of fungi cell wall and can be detected in clinical samples during the growth of the fungus in the patient. This study aimed to compare the galactomannan detection of Lateral Flow Assay and Enzyme Immunoassay methods in Bronchoalveolar Lavage Fluid. The galactomannan antigen in Bronchoalveolar Lavage Fluid was measured using Enzyme Immunoassay according to the manufacturer's instructions (PLATELIA ASPERGILLUS™ BioRad) and, using a Lateral Flow Assay according to the manufacturer's instructions (Galactomannan LFA IMMY©). The 71 samples were Bronchoalveolar Lavage Fluid of patients hospitalized at Unicamp Clinical Hospital between 2019 and 2021; of these samples 12/71 (16.9 %) resulted in positive Galactomannan-Lateral Flow Assay. In contrast, Galactomannan-Enzyme Immunoassay resulted as positive in 9/71 (12.6 %) samples, a difference that showed not significant statistically (p-value = 0.36) Comparing both assays' results identified 8 divergences between them, about 11 % of the total sample. The Sensitivity (73.3 %), Specificity (92.35 %), Positive Predictive Value (62.85 %) and Negative Predictive Value (95.15 %) of Lateral Flow Assay were calculated using the Galactomannan Enzyme Immunoassay as standard. The Lateral Flow Assay demonstrated good results when compared with the Enzyme Immunoassay.

Longitudinal Analysis of Mitochondrial Function in a Choline-Deficient L-Amino Acid-Defined High-Fat Diet-Induced Metabolic Dysfunction-Associated Steatohepatitis Mouse Model.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is one of the most common chronic liver diseases worldwide. Some patients with MAFLD develop metabolic dysfunction-associated steatohepatitis (MASH), which can lead to severe liver fibrosis. However, the molecular mechanisms underlying this progression remain unknown, and no effective treatment for MASH has been developed so far. In this study, we performed a longitudinal detailed analysis of mitochondria in the livers of choline-deficient, methionine-defined, high-fat-diet (CDAHFD)-fed mice, which exhibited a MASH-like pathology. We found that FoF1-ATPase activity began to decrease in the mitochondria of CDAHFD-fed mice prior to alterations in the activity of mitochondrial respiratory chain complex, almost at the time of onset of liver fibrosis. In addition, the decrease in FoF1-ATPase activity coincided with the accelerated opening of the mitochondrial permeability transition pore (PTP), for which FoF1-ATPase might be a major component or regulator. As fibrosis progressed, mitochondrial permeability transition (PT) induced in CDAHFD-fed mice became less sensitive to cyclosporine A, a specific PT inhibitor. These results suggest that episodes of fibrosis might be related to the disruption of mitochondrial function via PTP opening, which is triggered by functional changes in FoF1-ATPase. These novel findings could help elucidate the pathogenesis of MASH and lead to the development of new therapeutic strategies.

Validation of late recurrence prediction by gene expression profiles and clinicopathological factors in estrogen receptor-positive breast cancer.

BACKGROUND: The mechanism of late recurrence (LR) of estrogen receptor (ER)-positive breast cancer remains unclear, as previous studies have separately investigated "gene expression profiles" and "clinicopathological factors." Thus, this study aimed to evaluate the predictive capability of LR by combining the two independent factors of gene expression profiles (42-gene classifier: 42GC) and clinicopathological factors (Clinical Treatment Score post-5 years: CTS5) in multiple large cohorts. METHODS: We analyzed microarray CEL file data downloaded from public databases of 28 global cohorts. A total of 2,454 patients with ER-positive breast cancer were analyzed for 42GC, and 1,263 of these, with complete clinicopathological data were analyzed for CTS5. RESULTS: In the analysis of recurrent patients, the 42GC LR and CTS5 low-risk group tended to have LR. Notably, in the analysis of patients with and without recurrence, the highest LR rate beyond 5 years was observed in the CTS5 high-risk group. The combination of the 42GC and CTS5 high-risk groups showed the highest LR rate (16.9%), significantly exceeding that of the 42GC non-LR (NLR) and CTS5 low-risk combination (5.41%) (p = 0.038, odds ratio = 3.53). Furthermore, incorporating a third factor, 95GC, potentially reduced the number of patients prioritized for extended hormonal therapy for approximately one-quarter of patients. CONCLUSIONS: Results confirmed that the two factors, gene expression profiles and clinicopathological factors, affect the time of recurrence. It also showed that the biological predisposition for LR (CTS5 low-risk) differed from the high LR rate (CTS5 high-risk). In clinical practice, patients with the 42GC LR and CTS5 high-risk combination should be prioritized for extended hormonal therapy. The addition of CTS5 and 95GC to 42GC allows for better risk classification of LR.

Genetic Mutations in FKS1 Gene Associated with Acquired Echinocandin Resistance in Candida parapsilosis Complex.

Candida parapsilosis complex has recently received special attention due to naturally occurring FKS1 polymorphism associated with high minimal inhibitory concentrations for echinocandin and the increase of clonal outbreaks of strains resistant to commonly used antifungals such as fluconazole. Despite the previous fact, little is known about the genetic mechanism associated with echinocandin resistance. Therefore, the present study was designed to investigate the mechanism of acquired echinocandin resistance in C. parapsilosis complex strains. A total of 15 clinical C. parapsilosis complex isolates were sub-cultured for 30 days at a low concentration of micafungin at ½ the lowest MIC value of the tested isolates (0.12 µg/ml). After culturing, all the isolates were checked phenotypically for antifungal resistance and genotypically for echinocandin resistance by checking FKS1 gene hot spot one (HS1) and HS2 mutations. In vitro induction of echinocandin resistance confirmed the rapid development of resistance at low concentration micafungin, with no difference among C. parapsilosis, C. metapsilosis, and C. orthopsilosis in the resistance development. For the first time we identified different FKS1 HS1 and or HS2 mutations responsible for echinocandin resistance such as R658S and L1376F in C. parapsilosis, S656X, R658X, R658T, W1370X, X1371I, V1371X, and R1373X (corresponding to their location in C. parapsilosis) in C. metapsilosis, and L648F and R1366H in C. orthopsilosis. Our results are of significant concern, since the rapid development of resistance may occur clinically after short-term exposure to antifungals as recently described in other fungal species with the potential of untreatable infections.

Inherited CARD9 Deficiency Due to a Founder Effect in East Asia.

Autosomal recessive CARD9 deficiency can underly deep and superficial fungal diseases. We identified two Japanese patients, suffering from superficial and invasive Candida albicans diseases, carrying biallelic variants of CARD9. Both patients, in addition to another Japanese and two Korean patients who were previously reported, carried the c.820dup CARD9 variant, either in the homozygous (two patients) or heterozygous (three patients) state. The other CARD9 alleles were c.104G > A, c.1534C > T and c.1558del. The c.820dup CARD9 variant has thus been reported, in the homozygous or heterozygous state, in patients originating from China, Japan, or South Korea. The Japanese, Korean, and Chinese patients share a 10 Kb haplotype encompassing the c.820dup CARD9 variant. This variant thus originates from a common ancestor, estimated to have lived less than 4,000 years ago. While phaeohyphomycosis caused by Phialophora spp. was common in the Chinese patients, none of the five patients in our study displayed Phialophora spp.-induced disease. This difference between Chinese and our patients probably results from environmental factors. (161/250).

Disseminated Histoplasmosis presenting with panniculitis and macrophage activation syndrome in a patient undergoing immunosuppressive therapy for Mixed Connective Tissue Disease (MCTD).

Histoplasmosis, a fungal infection caused by Histoplasma capsulatum, is endemic in many parts of the world. However, this is not common in Japan. We herein present a unique case of military histoplasmosis in a 45-year-old female with mixed connective tissue disease (MCTD) who was receiving immunosuppressive therapy. The histological findings coupled with molecular confirmation led to final a diagnosis. This case emphasizes the diagnostic challenges associated with histoplasmosis in immunocompromised patients and underscores the importance of considering it in the differential diagnosis of any atypical presentation in rheumatic patients.

Early drain removal after hepatectomy based on bile leakage prediction using drainage fluid volume and direct bilirubin level.

AIMS: This study aimed to determine the value of the drainage fluid volume and direct bilirubin level for predicting significant bile leakage (BL) after hepatectomy and establish novel criteria for early drain removal. METHODS: Data from 351 patients who underwent hepatic resection at Gunma University in Japan between October 2018 and March 2022 were retrospectively analyzed. Clinical characteristics and surgical outcomes of patients with and without significant BL were compared. Criteria for early drain removal were determined and verified. RESULTS: Bile leakage occurred in 27 (7.1%) patients; 8 (2.3%) had grade A leakage and 19 (5.4%) had grade B leakage. The optimal cut-off value for the drainage fluid direct bilirubin level on postoperative day (POD) 2 was 0.16 mg/dL, which had the highest area under the curve and negative predictive value (NPV). Patients with BL had significantly larger drainage volumes on POD 2. The best cut-off value was 125 mL because it had the greatest NPV. Patients in both the primary and validation (n = 90) cohorts with bilirubin levels less than 0.16 mg/dL and drainage volumes less than 125 mL did not experience leakage. CONCLUSIONS: A drainage fluid volume less than 125 mL and direct bilirubin level less than 0.16 mg/dL on POD 2 are criteria for safe early drain removal after hepatectomy.

Phototoxicity avoidance is a potential therapeutic approach for retinal dystrophy caused by EYS dysfunction.

Inherited retinal dystrophies (IRDs) are progressive diseases leading to vision loss. Mutation in the eyes shut homolog (EYS) gene is one of the most frequent causes of IRD. However, the mechanism of photoreceptor cell degeneration by mutant EYS has not been fully elucidated. Here, we generated retinal organoids from induced pluripotent stem cells (iPSCs) derived from patients with EYS-associated retinal dystrophy (EYS-RD). In photoreceptor cells of RD organoids, both EYS and G protein-coupled receptor kinase 7 (GRK7), one of the proteins handling phototoxicity, were not in the outer segment, where they are physiologically present. Furthermore, photoreceptor cells in RD organoids were vulnerable to light stimuli, and especially to blue light. Mislocalization of GRK7, which was also observed in eys-knockout zebrafish, was reversed by delivering control EYS into photoreceptor cells of RD organoids. These findings suggest that avoiding phototoxicity would be a potential therapeutic approach for EYS-RD.

Investigation of recurrence prediction ability of EndoPredict® using microarray data from fresh frozen tissues in ER-positive, HER2-negative breast cancer and indication expansion of EndoPredict® from microarray data from fresh-frozen to FFPE tissues.

BACKGROUND: EndoPredict® (EP) is a multigene assay to predict distant recurrence risk in luminal breast cancer. EP measures the expression of 12 genes in primary tumor by qRT-PCR from formalin-fixed paraffin-embedded (FFPE) tissues and calculates EP risk score that indicates the risk of distant recurrence. We evaluated the performance of EP in predicting distant recurrence risk using microarray data from fresh frozen (FF) tissues. We also examined the applicability of EP to microarray data from FFPE tissues. METHODS: We analyzed the publicly available data of 431 node-negative and 270 node-positive patients with luminal breast cancer who received endocrine therapy alone. We evaluated the prognostic value of EP using microarray data from FF tissues. Next, we created an algorithm to calculate EP risk score using microarray data from FFPE tissues. We examined the correlation coefficient of EP risk score and concordance rate of EP risk high/low using microarray data from FFPE/FF tissue pairs in a validation set of 39 patients. RESULTS: In 431 node-negative patients, the distant recurrence-free survival (DRFS) rate was significantly worse in those with high EP risk scores (P = 3.68 × 10-6, log-rank). The 5-year DRFS was 95.2% in those with low EP risk score. In the validation set, the correlation coefficient of EP risk score was 0.93 and the concordance rate of EP risk high/low was 91.7%. CONCLUSIONS: EP using microarray data from FF tissues was useful in predicting distant recurrence risk in luminal breast cancer, and EP might be utilized in microarray data from FFPE tissues.

Nigrospora oryzae causing human corneal keratitis: A case report.

Purpose: We report a rare case of microbial keratitis caused by Nigrospora oryzae. Observations: A 72-year-old Japanese woman was injured by plant debris and developed oval corneal ulcers and hypopyon in the anterior chamber. After 5 days, she complained of pain, redness, and vision loss in her left eye and was treated with antibacterial eye drops and an ointment (1.5 % levofloxacin hydrate, cefmenoxime hydrochloride, and sterilization and disinfection eye drops; SAN-IODE and ofloxacin ophthalmic ointment). Examination revealed a worsening oval corneal ulcer with Descemet's folds and a faint hypopyon. Considering the infection from soil or plants and the poor response to intensive antibacterial eye drops, topical antifungal eye drops, i.e., 1 % voriconazole eye drops, and 1 % natamycin ointment were applied. Direct microscopy of the corneal scraping with Gram staining was performed and the result was negative. Cultures from corneal scrapings showed the growth of dark colonies after several days. The colony was identified as Nigrospora oryzae by sequencing of the fungal internal transcribed spacer region. Pain and vision loss improved with improvement in corneal ulcers. The antifungal treatment was administered for 37 days. Discontinuation of the eye drops after 1 month did not result in keratitis recurrence. At the final follow-up at 70 days, the best-corrected visual acuity was 20/25, with persistent small corneal opacity. Conclusions and importance: Here, we report a case of fungal keratitis caused by Nigrospora oryzae. Microbiological identification of the causes of rare infections is difficult in clinical laboratories, necessitating the use of advanced molecular techniques based on amplification and sequencing of appropriate phylogenetic markers. Nigrospora oryzae responds to topical voriconazole and natamycin.

Safety and effectiveness of certolizumab pegol in Japanese patients with rheumatoid arthritis: Up to 3-year results from a postmarketing surveillance study.

OBJECTIVES: To report up to 3-year safety and effectiveness of certolizumab pegol (CZP) in Japanese patients with rheumatoid arthritis from a postmarketing surveillance study. METHODS: Patients enrolled previously completed 24 weeks of CZP in the 24-week postmarketing surveillance study. Adverse drug reactions (ADRs) were recorded for patients who received ≥1 CZP dose. Effectiveness outcomes were 28-joint Disease Activity Score with erythrocyte sedimentation rate and European Alliance of Associations for Rheumatology response. Week 24-156 safety and Week 0-52 effectiveness data are reported here. RESULTS: A total of 781 patients were enrolled, with 735 and 376 patients evaluated for safety and effectiveness, respectively. Within the safety set, 17.8% (131/735) of patients reported ADRs; 9.4% (69/735) reported serious ADRs. Among patients with history of respiratory, thoracic, and mediastinal disorders, 38.4% (28/73) reported ADRs. The most frequent ADRs were infections and infestations (11.8%; 87/735); skin and subcutaneous tissue disorders (1.9%; 14/735); respiratory, thoracic, and mediastinal disorders (1.6%; 12/735). Mean 28-joint Disease Activity Score with erythrocyte sedimentation rate reduced from 4.6 (Week 0) to 2.8 (Week 52). At Week 52, 51.8% (161/311) of patients achieved European Alliance of Associations for Rheumatology Good response. CONCLUSIONS: The long-term safety and effectiveness of CZP in the real-world setting in Japan were consistent with previously reported data; no new safety signals were identified.

Perioperative pancreaticoduodenectomy management strategy focusing on postoperative early drain colonization.

PURPOSE: Pancreatoduodenectomy (PD) is a highly invasive procedure. Intra-abdominal infections and pancreatic fistulas are strongly correlated complications. In the present study, we identified the risk factors for postoperative early drain colonization (POEDC) and established a perioperative management strategy. METHODS: A total of 205 patients who underwent pancreatoduodenectomy were included in the study. POEDC was defined as a positive drain fluid culture before postoperative day (POD) 4. We retrospectively investigated the correlation between POEDC, postoperative outcomes, and clinical factors. RESULTS: POEDC was observed in 26 patients (12.6%) with poor postoperative outcomes, including pancreatic fistulas (P < 0.001). A multivariate analysis demonstrated a correlation between these postoperative outcomes and the age (P = 0.002), body mass index (BMI) (P = 0.002), procalcitonin (PCT) level (P < 0.001), and drain amylase level on POD 1 (P = 0.032). Enterococcus was detected most frequently, being found in 15 patients. CONCLUSION: We observed a strong correlation between POEDC and poor postoperative outcomes. The BMI, age, and PCT and drain amylase level on POD 1 should be considered POEDC risk factors, with the need to propose an antibiotic perioperative strategy. POEDC control may represent the key to improving postoperative outcomes after PD.
