Objective: To evaluate the efficacy and tolerability of ruxolitinib combined with prednisone, thalidomide and danazol for treatment of in myelofibrosis (MF). Methods: Patients of MF according to the WHO 2016 criteria, received ruxolitinib (RUX) combined with prednisone, thalidomide and danazol (PTD). The response, changes of blood counts and adverse events were evaluated. Results: Six PMF and one post-ET MF patients were enrolled. Four patients presented JAK2V617F mutation, one CALR mutation, one MPL mutation, one triple-negative. Responses per IWG-MRT criteria were clinical improvement in 5 patients, stable disease in 2 ones, spleen response in 6 ones. All of 7 patients were symptomatic responses, four patients achieved at least 50% improvement from baseline on MPN-SAF TSS. Three patients initially treated with RUX alone, all of 3 patients experienced treatment-associated anemia and thrombocytopenia. Then these 3 patients received RUX combined with PTD, both hemoglobin and platelet increased significantly. Four patients initially treated with RUX combined with PTD. Increased levels of hemoglobin and platelet were seen in all of 7 patients received RUX combined with PTD with maximum increased hemoglobin of 30(18-54) g/L and maximum increased platelets of 116(13-369)×10(9)/L, respectively from baseline. The treatment dose of RUX increased due to improved platelet count in 3 patients. The frequent non-hematologic adverse events grade 1-2 were constipation, abdominal distension, crura edema and increased ALT. Conclusions: RUX combined with PTD for treatment of MF may modulate initial hematologic toxicity observed when RUX alone, and may increase response due to improved levels of hemoglobin or platelet.

Breast cancer is currently the most prevalent cancer in women, and its incidence increases every year. Azole antifungal drugs were recently found to have antitumor efficacy in several cancer types. They contain an imidazole (clotrimazole and ketoconazole) or a triazole (fluconazole and itraconazole) ring. Using human breast adenocarcinoma cells (MCF-7 and MDA-MB-231), we evaluated the effects of azole drugs on cell proliferation, apoptosis, cell cycle, migration, and invasion, and investigated the underlying mechanisms. Clotrimazole and ketoconazole inhibited the proliferation of both cell lines while fluconazole and itraconazole did not. In addition, clotrimazole and ketoconazole inhibited the motility of MDA-MB-231 cells and induced G₁-phase arrest in MCF-7 and MDA-MB-231 cells, as determined by cell cycle analysis and immunoblot data. Moreover, Transwell invasion and gelatin zymography assays revealed that clotrimazole and ketoconazole suppressed invasiveness through the inhibition of matrix metalloproteinase 9 in MDA-MB-231 cells, although no significant changes in invasiveness were observed in MCF-7 cells. There were no significant changes in any of the observed parameters with fluconazole or itraconazole treatment in either breast cancer cell line. Taken together, imidazole antifungal drugs showed strong antitumor activity in breast cancer cells through induction of apoptosis and G₁ arrest in both MCF-7 and MDA-MB-231 cells and suppression of invasiveness via matrix metalloproteinase 9 inhibition in MDA-MB-231 cells. Imidazole drugs have well-established pharmacokinetic profiles and known toxicity, which can make these generic drugs strong candidates for repositioning as antitumor therapies.

BACKGROUND: Candidemia has increased with an increasing number of people in the high risk group and so has become more important. This study was conducted to investigate the isolation rate of Candida species from candidemia patients and the change in rate of antifungal resistance. METHODS: At a single tertiary care hospital, 1,120 blood cultures positive for Candida species from 1997 to 2016 were investigated according to date of culture, gender, age, and hospital department. RESULTS: During the investigation period, the number of candidemia patients increased from 14 in 1997 to 84 in 2016. The most common organism identified during the two decades was Candida albicans (40.8%), followed by Candida parapsilosis (24.1%), Candida tropicalis (13.2%), and Candida glabrata (12.8%). C. glabrata was relatively common in females (45.5%) compared to males. The age group 40-89 years was more frequently infected than other age groups, and the most frequent isolates according to age group were C. albicans in neonate (66.7%), C. parapsilosis in 1-9-year-olds (41.7%), and C. glabrata in those aged ≥60 years (range; 13.3%–20.0%). According to the visited departments, C. albicans, C. glabrata, and Candida haemulonii were more common in medical departments, while C. parapsilosis was more common in surgical departments. In the antifungal susceptibility test, a rising trend of azole resistance among C. albicans and C. glabrata was observed in recent years. CONCLUSION: In this study, it was confirmed that the isolation rate of Candida species in blood is different by age, gender, and hospital department, and the distribution of isolated Candida species changed over time. The resistance patterns of antifungal agents are also changing, and continuous monitoring and proper selection of antifungal agents are necessary.

A 37-year-old female presented to our hospital with a history of bleeding episodes (excessive bleeding after tooth extraction, gum bleeding, easy bruising, and excessive menstruation) and severe thrombocytopenia (2,000/µL). She had no family history of bleeding tendency or thrombocytopenia. No peripheral lymphadenopathy or splenomegaly was noted. The patient's white blood cell count was normal; hemoglobin was 9.7 g/dL. A peripheral blood smear showed markedly decreased platelets, with occasional giant or large platelets. Bone marrow examination found increased megakaryocytes. The patient also complained of hearing difficulty; a hearing test indicated sensory-neural hearing impairment. Her thrombocytopenia was refractory to treatment with glucocorticosteroids, intravenous gamma-globulin, and danazol. In the 13 years following her initial presentation, the patient required anti-hypertensive treatment, a hearing-aid for progressive hearing loss, and started maintenance kidney dialysis. Her clinical history of refractory thrombocytopenia, progressive hearing impairment, and renal failure suggested myosin heavy chain 9 gene-related congenital syndrome (Epstein syndrome), which was confirmed by the presence of a heterozygous deletion mutation, c.221_223del, (p.Lys74del) in peripheral leukocyte deoxyribonucleic acid.

A yeast-like organism was isolated from a urine sample of a 6-year-old neutered male miniature poodle dog with urinary tract infection, diabetes ketoacidosis, and acute pancreatitis. We identified the yeast-like organism to be Candida glabrata and found that this fungus was highly resistant to azole antifungal drugs. To understand the mechanism of azole resistance in this isolate, the sequences and expression levels of the genes involved in drug resistance were analyzed. The results of our analysis showed that increased drug efflux, mediated by overexpression of ATP transporter genes CDR1 and PDH1, is the main cause of azole resistance of the C. glabrata isolated here.

Cyberlindnera fabianii (previously known as Hansenula fabianii, Pichia fabianii, and Lindnera fabianii) is a yeast species that forms a biofilm, allowing it to resist azole drugs. In this study, we report a case of fungemia with C. fabianii that was successfully treated with anidulafungin. In this case, the organism was initially misidentified as Candida utilis (with a high probability of 93%, suggesting good identification) using the VITEK 2 yeast identification card (YST ID; bio-Merieux, USA). The species responsible for the patient's fungemia was correctly identified after sequencing the internally transcribed spacer region and the D1/D2 domain of the large subunit (26S) rDNA gene. The CLSI M27-A3 broth microdilution method was used to determine the in vitro antifungal activity of anidulafungin and fluconazole against C. fabianii. The MICs of anidulafungin and fluconazole were found to be 0.03 microg/mL and 2 microg/mL, respectively. The patient recovered after 14 days of anidulafungin treatment.

Thoracic endometriosis (TE) is an uncommon disorder affecting women of childbearing age. We herein report clinical and thin-section computed tomography (CT) findings of two cases, in which one woman presented with catamenial haemoptysis (CH) alone and another woman presented with bilateral catamenial pneumothoraces (CP) coinciding with CH, a rare manifestation of TE. The dynamic changes demonstrated on thin-section chest CT performed during and after menses led to accurate localisation and presumptive diagnosis of TE in both patients. Following danazol treatment, the patient with CH alone had a complete cure, while the patient with CP and CH had an incomplete cure and required long-term danazol treatment. We discuss the role of imaging studies in TE, with an emphasis on the appropriate timing and scanning technique of chest CT in women presenting with CH, potential mechanisms, treatment and patient outcomes.
