Curcumin as adjuvant therapy to improve remission in myeloma patients: A pilot randomized clinical trial.

Background: The treatment for ineligible transplant multiple myeloma is melphalan prednisone. Curcumin has an anti-inflammatory and antiangiogenesis in cancer-directed to nuclear factor-kappa B (NF-kB) pathway. Interleukin 6 (IL-6), vascular endothelial growth factor (VEGF), tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), and lactate dehydrogenase (LDH) were also involved in the pathogenesis of myeloma. No clinical study has evaluated the efficacy of curcumin in myeloma patients. To evaluate the efficacy of curcumin as adjuvant into melphalan prednisone in myeloma patients. Methods: 33 myeloma patients at Dr. Kariadi General Hospital, Semarang, Indonesia during 2016-2017 were randomly assigned single-blindedly into MPC (n=17) and control group (n=16). The MPC group was treated with melphalan 4 mg/m2, prednisone 40 mg/m2 for 7 days, and curcumin 8 gram daily for 28 days. The MP control group was treated with melphalan, prednisone, and placebo. The primary endpoint was the overall remission. Pre- and post-treatment was examined for NF-κB, VEGF, TNF-α, IL-6, LDH, and CRP levels All data analyses were per protocol. Results: There was a significant difference in overall remission between the MPC and MP control groups [75%vs 33.3%, x2=6.89, P=0.009]. A significant decrease of NF-κB, VEGF, TNF-α levels were shown in the MPC group compared with the MP control group. There was a significant decrease in IL-6 levels in a subgroup analysis of the MPC group. TNF-α levels had a significant correlation with remission [OR=1.35; (95%CI=1.03-1.76); P=0.03]. Conclusion: Curcumin has an efficacy in improving overall remission and decreasing NF-κB, VEGF, TNF-α, and IL-6 levels in myeloma patients.

Second-Hand Smoke and Its Synergistic Effect with a Body-Mass Index of >24.9 kg/m2 Increase the Risk of Gout Arthritis in Indonesia.

To analyze the association between smoking status (active smoking and exposure to Second-Hand Smoking (SHS)) and the synergistic effect of smoking status and BMI with gout risk, a community-based case-control design was undertaken among 385 participants, including 304 healthy controls and 81 gout patients from seven community health services. Adjusted Odd Ratios (AORs) and 95% Confidence Interval (CIs) of gout for active smoking and SHS were 3.26 (95% CI = 1.07~9.90) and 4.67 (95% CI = 2.18~10.00) compared to non-smokers. Time-dependent manner of active smoking and SHS significantly increased gout risk with AORs and 95% CIs of 5.95 (1.41~25.03) and 10.12 (3.51~29.14). Dose-dependency of active smokers and SHS showed AORs and 95% CIs of 5.15 (1.28~20.63) and 4.37 (1.33~14.28). Smoking 20 cigarettes (one pack) per day for one year is equivalent to one pack-year. Active smoking >20 pack-year and SHS > 26.5 pack-year increased gout risk with AORs and 95% CIs of 7.18 (1.53~33.67) and 9.95 (3.64~27.22). Participants who smoked (active smoking and SHS) and with Body Mass Index (BMI) of > 24.9 kg/m2 synergistically increased gout risk, with an AOR of 9.65 and 95% CI of 3.25~28.65, compared to BMI ≤ 24.9 kg/m2 and non-smoker. Smoking status (active smoking and SHS) and the synergistic effect of smoking status and BMI increased gout risk in Indonesia.

Autologous Bone Marrow Transplant in Multiple Myeloma Patient With Bone Marrow Hematopoietic Stem Cell.

Multiple myeloma (MM) is a malignancy with multiple complications such as recurrent bacterial infections, anemia, osteolytic lesions, bone marrow failure and decreased kidney function. In developed transplant center, the bone marrow transplant procedure is performed by the source of peripheral blood stem cells. Apheresis machine which is not always available in all Haematology and Oncology Centre in Indonesia, is required for harvesting stem cell from PBSC (peripheral blood stem cell). There are only a few reports on marrow-derived stem cells transplant from BM with a 24-hour storage in multiple myeloma cases. We report two cases with non-secretory myeloma stage III and IgG myeloma stage II (International Staging System). Both patients were treated with induction regimens CyBord until a complete remission. Once remission was achieved, an autologous bone marrow transplant procedures were performed. The source of haematopietic stem cells (HSCs) were harvested from bone marrow and stored for 24 hours at a temperature of 4◦ C. The complications were neutropenia, anemia, thrombocytopenia, mucositis, diarrhea, hair loss, and skin darkness. The HSCs grew well on day 12 and 23. After treatment in the isolation room, the patient's condition improved and the patients were discharged.

Role of micronize purified flavonoid fraction and ethanol Graptophyllum pictum extract on experimental anal ulcer healing. Study on Wistar rat / Papel da fração flavonoica purificada micronizada e do extrato etanólico de Graptophyllum Pictum em experimento de cicatrização de úlcera anal. Estudo com ratos Wistar

ABSTRACT Aim of the study To evaluate the role of micronized purified flavanoid fraction and ethanol Graptophyllum pictum extract in the treatment of anal ulcer. Method Twenty-eight Wistar rats were randomly allocated into four groups. Groups 2, 3 and 4 the anus were induced with croton oil, but was not induced on group 1. Groups 1 and 2 were treated with normal saline, while groups 3 and 4 were treated with micronized purified flavanoid fraction, and ethanol G. pictum extract, respectively. On 9th days blood sample were taken from the retro-orbital region, and Wistar was killed by cervical dislocation under ether anesthesia. The anal canal was resected up 2 cm from anal opening, weighted, photographically taken to measure the percentage of residual ulcer, and then prepared for microscopic examination. Elisa methods were done for superoxide dismutase and malondialdedhyde. The total leukocyte in the anal specimen was counted under 400 magnification power. superoxide dismutase, anal coefficient, and total leukocyte for statistical analysis were using ANOVA and LSD, while malondialdedhyde and percentage of ulcers were using Kruskal-Wallis and Mann-Whitney. Result Treatment with ethanol G. pictum extract dose of 100 mg/kg BW significantly reduces the percentage of anal ulcer, the edema, leukocyte infiltration, and malondialdedhyde, and increase the superoxide dismutase in comparison without treatment. Treatment with micronized purified flavanoid fraction did not reduce the leukocyte, anal coefficient, and percentage of anal ulcer, only increase malondialdedhyde and decrease superoxide dismutase significantly.

RESUMO Objetivo do estudo Avaliar o papel da Fração Flavonoica Purificada Micronizada e do Extrato Etanólico de Graptophyllum pictum no tratamento de úlcera anal. Método Vinte e oito ratos Wistar foram randomicamente alocados em quatro grupos. Nos grupos 2, 3 e 4, indução com óleo de cróton foi realizada no ânus, excetuando-se o Grupo 1. Os grupos 1 e 2 foram tratados com solução salina normal, enquanto os grupos 3 e 4 foram tratados com fração flavonoica purificada micronizada e extrato etanólico de Graptophyllum pictum, respectivamente. No nono dia, amostras de sangue foram colhidas da região retroorbital, e o rato Wistar sofreu eutanásia por deslocamento cervical sob anestesia com éter. O canal anal foi ressecado até 2 cm da abertura anal, ponderado e fotografado para medir a porcentagem de úlcera residual e, em seguida, preparado para exame microscópico. Os métodos superoxide dismutase e malondialdedhyde do ensaio Elisa foram realizados. A contagem total de leucócitos foi realizada na amostra anal com ampliação de 400 vezes. ANOVA e LSD foram utilizados para a análise estatística de superoxide dismutase, coeficiente anal e número total de leucócitos, enquanto os testes de Kruskal-Wallis e Mann-Whitney foram utilizados para a análise de malondialdedhyde e porcentagem de úlceras. Resultado O tratamento com o extrato etanólico de Graptophyllum pictum (100 mg/kg de peso corporal) reduz de modo significativo a porcentagem de úlceras anais, o edema, a infiltração de leucócitos e o malondialdedhyde e aumenta a superoxide dismutase, comparado ao não tratamento. O tratamento com a fração flavonoica purificada micronizada não reduziu os leucócitos, o coeficiente anal e a porcentagem de úlceras anais, apenas aumentou o malondialdedhyde e diminuiu significativamente a superoxide dismutase.

Inhibitory Effect of Alpha-Mangostin to Dengue Virus Replication and Cytokines Expression in Human Peripheral Blood Mononuclear Cells.

Massive pro-inflammatory cytokines production has been correlated with the pathogenesis of severe dengue disease. The active compound of mangosteen fruit pericarps, α-mangostin, has been commonly used as traditional medicine and dietary supplement. We examined the effect of α-mangostin against dengue virus (DENV) infection in human peripheral blood mononuclear cells (PBMC) by the measurement of virus titer and TNF-α and IFN-γ cytokines concentration post infection. Increasing concentration of α-mangostin inhibited virus replication and reduced inflammatory cytokines expression at 24- and 48-h post infection. Our results support the potential use of α-mangostin as anti-antiviral and anti-inflammatory therapies in the treatment of dengue.

Effects of Omega-3 Supplementation on Ki-67 and VEGF Expression Levels and Clinical Outcomes of Locally Advanced Breast Cancer Patients Treated with Neoadjuvant CAF Chemotherapy: A Randomized Controlled Trial Report

Background: Omega-3 is a polyunsaturated fatty acid with an ability to regulate cell proliferation and apoptosis through interaction with inflammatory mediators. The potential additional beneficial effects of Omega-3 on chemotherapy patients with breast cancer is not yet completely revealed. Methods: A double-blind randomized control trial (RCT) involving a total of 48 locally advanced breast cancer patients was conducted. Ki-67 and VEGF expressions, as well as overall survival of patients receiving neoadjuvant cyclophosphamide-doxorubicin-5'fluorouracyl (CAF) chemotherapy plus Omega-3 (intervention group) or placebo (control group), were compared. Kaplan-Meier curve and Cox-regression tests were used to assess conditional disease-free survival (DFS) and overall survival (OS) between the two groups. Results: Decreased Ki-67 expression was observed in the intervention group compared to control (42.4±4.8 versus 39.2±5.3; T-test p=0.032). Decreased Ki-67 expression was observed in intervention compared to control group (42.4±4.8 versus 39.2±5.3; T-test p=0.032). Decreased VEGF expression was also seen in the intervention group compared to control (32.7±5.2 versus 29.5±5.4; T-test p=0.041). VEGF expression positively correlated with Ki-67 expression (Spearman's test p<0.001, R2=0.541). Overall survival in the intervention group was significantly longer in comparison to the control group (mean survival: 30.9 ± 3.71 versus 25.9 ± 3.6 weeks, Mantel-Cox test p=0.048; HR=0.411, 95%CI: 0.201-0.840). Disease-free survival was significantly longer in the intervention group compared to the control group (mean survival: 28.5 ± 3.3 versus 23.7 ± 3.6, respectively; Mantel-Cox test p=0.044, HR= 0.439, 95%CI: 0.222-0.869). Conclusion: Omega-3 fatty acid supplementation improved overall survival and progression-free survival of locally advanced breast cancer treated with CAF neoadjuvant chemotherapy and mastectomy.

Distribution of Voltage-Gated Sodium Channel (Nav) Alleles among the Aedes aegypti Populations In Central Java Province and Its Association with Resistance to Pyrethroid Insecticides.

The emergence of insecticide resistant Aedes aegypti mosquitoes has hampered dengue control efforts. WHO susceptibility tests, using several pyrethroid compounds, were conducted on Ae. aegypti larvae that were collected and raised to adulthood from Semarang, Surakarta, Kudus and Jepara in Java. The AaNaV gene fragment encompassing kdr polymorphic sites from both susceptible and resistant mosquitoes was amplified, and polymorphisms were associated with the resistant phenotype. The insecticide susceptibility tests demonstrated Ae, aegypti resistance to the pyrethroids, with mortality rates ranging from 1.6%-15.2%. Three non-synonymous polymorphisms (S989P, V1016G and F1534C) and one synonymous polymorphism (codon 982) were detected in the AaNaV gene. Eight AaNaV alleles were observed in specimens from Central Java. Allele 3 (SGF) and allele 7 (PGF) represent the most common alleles found and demonstrated strong associations with resistance to pyrethroids (OR = 2.75, CI: 0.97-7.8 and OR = 7.37, CI: 2.4-22.5, respectively). This is the first report of 8 Ae. aegypti AaNaV alleles, and it indicates the development of resistance in Ae. aegypti in response to pyrethroid insecticide-based selective pressure. These findings strongly suggest the need for an appropriate integrated use of insecticides in the region. The 989P, 1016G and 1534C polymorphisms in the AaNaV gene are potentially valuable molecular markers for pyrethroid insecticide resistance monitoring.

Molecular surveillance of dengue in Semarang, Indonesia revealed the circulation of an old genotype of dengue virus serotype-1.

Dengue disease is currently a major health problem in Indonesia and affects all provinces in the country, including Semarang Municipality, Central Java province. While dengue is endemic in this region, only limited data on the disease epidemiology is available. To understand the dynamics of dengue in Semarang, we conducted clinical, virological, and demographical surveillance of dengue in Semarang and its surrounding regions in 2012. Dengue cases were detected in both urban and rural areas located in various geographical features, including the coastal and highland areas. During an eight months' study, a total of 120 febrile patients were recruited, of which 66 were serologically confirmed for dengue infection using IgG/IgM ELISA and/or NS1 tests. The cases occurred both in dry and wet seasons. Majority of patients were under 10 years old. Most patients were diagnosed as dengue hemorrhagic fever, followed by dengue shock syndrome and dengue fever. Serotyping was performed in 31 patients, and we observed the co-circulation of all four dengue virus (DENV) serotypes. When the serotypes were correlated with the severity of the disease, no direct correlation was observed. Phylogenetic analysis of DENV based on Envelope gene sequence revealed the circulation of DENV-2 Cosmopolitan genotype and DENV-3 Genotype I. A striking finding was observed for DENV-1, in which we found the co-circulation of Genotype I with an old Genotype II. The Genotype II was represented by a virus strain that has a very slow mutation rate and is very closely related to the DENV strain from Thailand, isolated in 1964 and never reported in other countries in the last three decades. Moreover, this virus was discovered in a cool highland area with an elevation of 1,001 meters above the sea level. The discovery of this old DENV strain may suggest the silent circulation of old virus strains in Indonesia.

Effect of phaleria macrocarpa supplementation on apoptosis and tumor growth of C3H mice with breast cancer under treatment with adriamycin-cyclophosphamide.

The objective of this study was to know the response of supplementation of Phaleria macrocarpa (PM) to adriamycin-cyclophosphamide (AC) in the treatment of C3H mice with breast cancer. Twenty-four C3H mice, who were successfully inoculated with breast cancer cells, were randomly allocated into 4 groups: without treatment, treated with AC, treated with AC + PM 0.07 mg/d, and treated with AC + PM 0.14 mg/d. The tumor size was measured using millimeter calipers before and 12 weeks after treatment. The tumor, liver, and kidneys were removed and prepared for pathologic examination using imunohistochemistry staining, and the apoptotic index was counted using the terminal deoxynucleotidyl transferase dUTP nick end labeling method. AC reduce the tumor growth significantly (P < 0.001), whereas supplementation of PM, which significantly reduced the tumor growth compared with AC only, was at the 0.14 mg/d dose (P = 0.007). AC increase the apoptotic index significantly (P < 0.001), and supplementation with PM showed that the higher dose increased the apoptotic index. The correlation between the apoptotic index and the diameter of tumor was significantly negative (r = -0.884; P = 0.020). The apoptotic index of the liver and kidney increased significantly in the AC group (P < 0.001 and P = 0.002, respectively); supplementation with PM decreased significantly the high apoptotic index caused by AC. We conclude that PM supplementation has a synergic effect to AC treatment in reducing the tumor growth, by increasing apoptosis, and protects the liver and kidney from damage caused by AC.

Divergent effects of tumor necrosis factor-alpha and lymphotoxin-alpha on lethal endotoxemia and infection with live Salmonella typhimurium in mice.

During septic shock with Gram-negative microorganisms, mortality is determined by two independent factors: high concentrations of circulating proinflammatory cytokines and multiplication of the microorganisms in the organs of the host. We studied the role of endogenous tumor necrosis factor-alpha (TNF) and lymphotoxin-alpha (LT) in the pathogenesis of lethal endotoxemia and infection with viable Salmonella typhimurium. Compared to wild-type control mice, TNF-/-LT-/- knock-out mice were more resistant (100% versus 25% mortality) to a lethal challenge with LPS, due to a significantly decreased production of the proinflammatory cytokines TNF, IL-1alpha and IL-1beta. In contrast, TNF-/-LT-/- mice were highly susceptible to infection with viable S. typhimurium as compared to wild-type mice (100% versus 0% mortality), and this was accompanied by a 100-fold greater bacterial load in their organs. The effect of endogenous TNF and LT during infection was mediated by a defective recruitment of neutrophils at the site of infection, as well as a reduced intracellular killing of S. typhimurium by these cells. These results show that TNF and LT have crucial, yet opposite effects on lethal endotoxemia induced by S. typhimurium LPS and on the infection of mice with live Salmonella microorganisms, and suggest caution when extrapolating results obtained in the lethal endotoxemia model to bacteremia in patients.
