Abstract
Introduction Invasive fungal infections have been attracting attention as significant fatal complications in patients with febrile neutropenia (FN) who undergo intensive chemotherapy or hematopoietic stem cell transplantation to treat hematological malignancies. Although clinical trials are already underway in other countries, evidence supporting the use of caspofungin (CAS) in FN patients in Japan is still insufficient. Methods A retrospective study of patients treated with CAS for FN associated with hematological diseases between April 2015 and March 2018 was conducted to determine the treatment efficacy and safety. The study was conducted as a multicenter collaboration, and the data of 52 patients who met all of the inclusion criteria were analyzed. A five-composite-endpoint method was used, and the treatment was judged to be effective when all five endpoints (defervescence during neutropenia; no breakthrough fungal infections; resolution of baseline fungal infections; a survival for seven days or more after the completion of therapy; and no discontinuation of therapy due to side effects or invalidity) were met. Results The efficacy rate was 53.8% (28/52), which is close to the average reported efficacy rate. Adverse events included liver dysfunction and electrolyte abnormalities, but no renal dysfunction or serious events were seen. Conclusion These results suggest that the use of CAS in FN patients with hematological diseases is effective and well-tolerated, and we believe that the use of CAS could become a significant treatment in Japan.

Sitafloxacin reduces tumor necrosis factor alpha (TNFα) converting enzyme (TACE) phosphorylation and activity to inhibit TNFα release from lipopolysaccharide-stimulated THP-1 cells. Sci Rep 2021; 11:24154.

Abstract
Sepsis is a systemic reaction to an infection and resulting in excessive production of inflammatory cytokines and chemokines. It sometimes results in septic shock. The present study aimed to identify quinolone antibiotics that can reduce tumor necrosis factor alpha (TNFα) production and to elucidate mechanisms underlying inhibition of TNFα production. We identified quinolone antibiotics reduced TNFα production in lipopolysaccharide (LPS)-stimulated THP-1 cells. Sitafloxacin (STFX) is a broad-spectrum antibiotic of the quinolone class. STFX effectively suppressed TNFα production in LPS-stimulated THP-1 cells in a dose-dependent manner and increased extracellular signal-regulated kinase (ERK) phosphorylation. The percentage of intracellular TNFα increased in LPS-stimulated cells with STFX compared with that in LPS-stimulated cells. TNFα converting enzyme (TACE) released TNFα from the cells, and STFX suppressed TACE phosphorylation and activity. To conclude, one of the mechanisms underlying inhibition of TNFα production in LPS-stimulated THP-1 cells treated with STFX is the inhibition of TNFα release from cells via the suppression of TACE phosphorylation and activity. STFX may kill bacteria and suppress inflammation. Therefore, it can be effective for sepsis treatment.

Abstract
Systemic inflammatory response syndrome and sepsis are considered to contribute to hypercytokinemia in both patients with severe infection and immunocompromised condition. Past research has demonstrated that antibiotics and antifungals not only have antimicrobial efficacy but also affect the immune system. We previously examined whether immune cells were modulated by antibiotics such as tetracyclines or macrolides. The modulation of lipopolysaccharide-stimulated cells by those agents was elucidated. However, few reports about the modulation of the immune system by antifungal agents were found. In this study, the production of pro-inflammatory cytokines and chemokines and signaling pathways involved were investigated in zymosan-activated THP-1 cells. The effects were examined using antifungal agents such as echinocandin including caspofungin (CAS) and micafungin. Pro-inflammatory cytokine and chemokine levels were determined using enzyme-linked immunosorbent assay. Protein phosphorylation was evaluated by western blot analysis. CAS significantly decreased zymosan-induced pro-inflammatory cytokine and chemokine release in THP-1 cells. CAS (30 µg/mL) also downregulated tumor necrosis factor alpha levels, as shown by enzyme-linked immunosorbent assay. In western blot analysis, inhibitor of nuclear factor-kappa-B alpha, p38, c-Jun N-terminal kinase, extracellular signal-regulated kinase, and nuclear factor of activated T-cells phosphorylation and activation of caspase-1 and spleen tyrosine kinase (Syk) were downregulated. The major underlying mechanism of pro-inflammatory cytokine and chemokine suppression by CAS is to inhibit activation of Syk and its downstream signaling molecules. Based on the results, it can be concluded that CAS activity possibly involves Syk signaling pathways and has potential to prevent hypercytokinemia in fungal sepsis.

Abstract
Candida peritonitis is a crucial disease, however the optimal antifungal therapy regimen has not been clearly defined. Peritoneal fibrosis (PF) can be caused by abdominal surgery, intra-abdominal infection, and malignant diseases, and is also widely recognized as a crucial complication of long-term peritoneal dialysis. However, the influence of PF on Candida peritonitis prognosis remains unknown. Here, we evaluated the severity of Candida peritonitis within the context of PF and the efficacy of micafungin using mice. A PF mouse model was generated by intraperitoneally administering chlorhexidine gluconate. Candida peritonitis, induced by intraperitoneal inoculation of Candida albicans, was treated with a 7-day consecutive subcutaneous administration of micafungin. Candida infection caused a higher mortality rate in the PF mice compared with the control mice on day 7. Proliferative Candida invasion into the peritoneum and intra-abdominal organs was confirmed pathologically only in the PF mice. However, all mice in both groups treated with micafungin survived until day 20. Micafungin treatment tends to suppress inflammatory cytokines in the plasma 12 h after infection in both groups. Our results suggest that PF enhances early mortality in Candida peritonitis. Prompt initiation and sufficient doses of micafungin had good efficacy for Candida peritonitis, irrespective of the underlying PF.

Abstract
BACKGROUND We conducted a comparative clinical study to evaluate the prophylactic effects of micafungin (MCFG) and fluconazole (FLCZ) on the incidence of fungal infections in extremely low-birthweight infants who were born at a gestational age of less than 26 weeks and weighed less than 1000 g. METHODS With a combination of enteral administration of miconazole (6 mg/kg/day), FLCZ and MCFG were administered intravenously at a dose of 5 mg/kg/day and 3 mg/kg/day, respectively. The prophylaxis was classified as a failure when fungal infections were identified within the first 21 days after birth. RESULTS The prophylaxis was successful in seven of 18 cases (39%) in the FLCZ group and 15 of 21 cases (71%) in the MCFG group, indicating that the success rate was significantly higher in the latter group. CONCLUSION MCFG was superior to FLCZ as prophylaxis against fungal infections in extremely low-birthweight infants.

Abstract
Mucormycosis is a rare, invasive and fatal disease that occurs mainly in diabetes mellitus patients with uncontrolled blood glucose levels or in immunocompromised patients. The mortality rate of this disease is as high as 25 to 80%, despite aggressive surgical treatment and antifungal therapy. This high mortality requires alternative treatment approaches. The accepted treatment modality of invasive mucormycosis are amphotericin B lipid formulations. Although echinocandins generally show no activity against Mucorales, it was shown that Rhizopus oryzae expressed the target enzyme for echinocandins, 1,3-beta-glucan synthase. Additionally, there are some experimental studies in a diabetic mouse model and case reports regarding the effects of caspofungin. In this report, we present a rhinocerebral mucormycosis case treated with liposomal amphotericin B and caspofungin. There was regression of the patient's clinical and radiological condition with the addition of caspofungin, but she died due to discontinuation of her treatment and reasons other than mucormycosis.

Abstract
Minocycline, which is a member of the broad-spectrum bacteriostatic tetracycline antibiotics group, has also recently been shown to have additional effects that are separate from their antimicrobial function; however, the detailed mechanisms involved remain unknown. We examined the effects of minocycline on cytokine and chemokine production and the expression levels of intracellular phosphorylated proteins in a lipopolysaccharide (LPS)-induced cytokine response model in vitro. In the present study, 3 cytokines (tumor necrosis factor [TNF]-α, interleukin [IL]-6, and interferon [IFN]-γ) and 7 chemokines (IL-8, interferon inducible protein [IP]-10, monocyte chemoattractant protein [MCP]-1, macrophage inflammatory protein [MIP]-1α, MIP-1β, regulated upon activation normal T-cell expressed secreted [RANTES], and eotaxin) were suppressed by minocycline in a dose-dependent manner. Moreover, the phosphorylation of inhibitor of nuclear factor-κB alpha (IκBα) and IκB kinase (IKK)α/β, which is located upstream from IκBα, was significantly suppressed by minocycline, whereas the phosphorylation of extracellular signal-regulated kinase (ERK)1/2, c-Jun N-terminal kinase (JNK), p38, and TGF-β-activated kinase (TAK)1 were not affected. Thus, minocycline appears to inhibit the signaling pathway at the level of IKKα/β phosphorylation. In conclusion, minocycline was found to reduce the production of multiple cytokines and chemokines by inhibiting LPS-induced IKKα/β phosphorylation. That is, minocycline appears to be a potent inhibitor of IKKα/β phosphorylation. From a clinical and translational significance point-of view, these findings suggest that the use of minocycline offers the advantage of providing both antimicrobial and anti-inflammatory effects, which may be key in treating certain types of infectious diseases, particularly those that lead to hypercytokinemia and chronic inflammatory disorders.

Abstract
BACKGROUND It has been axiomatic that echinocandins (e.g., caspofungin) are ineffective against mucormycosis. However, on the basis of preclinical data, we recently began treating rhino-orbital-cerebral mucormycosis (ROCM) with combination polyene-caspofungin therapy. METHODS To determine the impact of polyene-caspofungin therapy, ROCM cases identified by an International Classification of Diseases, Ninth Revision search were retrospectively reviewed to gather data on demographic characteristics, clinical history, and outcomes. The predefined primary end point was success (i.e., the patients was alive and not in hospice care) at 30 days after hospital discharge. RESULTS Forty-one patients with biopsy-proven ROCM were identified over 12 years; 23 (56%) of these patients were Hispanic, and 34 (83%) were diabetic. Patients treated with polyene-caspofungin therapy (6 evaluable patients) had superior success (100% vs. 45%; Pp.02) and Kaplan-Meier survival time (Pp.02), compared with patients treated with polyene monotherapy. Patients treated with amphotericin B lipid complex had inferior success (37% vs. 72%; Pp.03) and a higher clinical failure rate (45% vs. 21%; Pp.04), compared with patients who received other polyenes. However, patients treated with amphotericin B lipid complex plus caspofungin had superior success (100% vs. 20%; Pp.009) and survival time (Pp.01), compared with patients who received amphotericin B lipid complex alone. The benefit of combination therapy, compared with monotherapy, was most pronounced in patients with cerebral involvement (success rate, 100% vs. 25%; Pp.01). In multivariate analysis, only receipt of combination therapy was significantly associated with improved outcomes (odds ratio, 10.9; 95% confidence interval, 1.3- ;Pp.02). CONCLUSIONS Combination polyene-caspofungin therapy represents a promising potential alternative to polyene monotherapy for patients with ROCM. Randomized, prospective investigation of these findings is warranted.

Abstract
We previously found that caspofungin synergized with amphotericin B lipid complex in treating murine mucormycosis. We now report a similarly enhanced activity of liposomal amphotericin combined with micafungin or anidulafungin in mice with disseminated mucormycosis. The efficacy of combination echinocandin-polyene therapy for mucormycosis is a class effect.
