Effect of Phaleria Macrocarpa (Scheff.) Boerl Leaf Ethanol Extract on Serum IL-6 and TNF-α Levels in Diabetic Rats.

Background: Hyperglycemia conditions in diabetes mellitus (DM) can turn on pro-inflammatory cytokines like IL-6 and TNF-α. These cytokines play a role in insulin resistance and the development of DM complications. People in Indonesia have used Phaleria macrocarpa to treat diabetes, but the leaf of this plant has not been studied to see if it can reduce inflammation. Objective: This study aims to analyze the effect of ethanolic extract of Phaleria macrocarpa leaves (EEPML) in serum IL-6 and TNF-α levels of diabetic rats. Methods: This study was an experiment with a post-test-only control group design. Thirty 8-week-old male Wistar rats were used in the study. They were split into six groups: K1 was the normal control group; K2 was the DM control group; K3, K4, and K5 were given EEPML at doses of 125, 250, and 500 mg/KgBW; and K6 was given metformin 45 mg/KgBW orally once a day for 14 days. A high-fat diet and a 30 mg/KgBWi.p injection of streptozotocin were used to make the diabetic rat model. ELISA method for measuring serum IL-6 and TNF-α levels. The Kruskal-Wallis and the Mann-Whitney test were used to examine the differences between the groups. Results: There were significant differences between treatment groups in the mean levels of serum IL-6 (p=0.017), but there were no significant differences in the mean levels of serum TNF-α (p>0.05). Conclusion: Administration of Phaleria macrocarpa leaf ethanol extract 125 mg/KgBW reduced serum IL-6 levels but could not significantly reduce serum TNF-α levels in diabetic rats.

Factors influencing histoplasmosis incidence in multidrug-resistant pulmonary tuberculosis patients: A cross-sectional study in Indonesia.

Histoplasmosis is an infectious disease caused by the dimorphic fungus Histoplasma capsulatum, which in chronic conditions, is generally difficult to distinguish from pulmonary tuberculosis (TB) based on its clinical appearance; therefore, diagnostic errors could occur. Meanwhile, the prevalence of multidrug-resistant pulmonary TB (MDR-TB) in Indonesia remains high. Study determining the incidence of histoplasmosis in MDR-TB is unavailable worldwide. The aim of this study was to determine the risk factors of histoplasmosis incidence in MDR-TB patients in Indonesia. A cross-sectional was conducted at H. Adam Malik General Hospital, Medan, Indonesia and the ELISA platform (semi-quantitative) was used to detect histoplasma antibodies. Factors associated with histoplasmosis incidence among MDR-TB were determined using a Chi-squared test. A total of 50 MDR-TB patients were included this study of which 14 of them (28%) had histoplasmosis. The majority of histoplasmosis occurred in males, in MDR-TB patients with a history of TB treatment and among who had chest x-rays with far-advanced lesions. However, statistical analyses indicated none of those factors (sex, TB treatment history, status of the lung) as well as age group, acid-fast bacillus result, Mycobacterium tuberculosis culture result, having pet, living in damp house, working in the field or plantation, having HIV infection and smoking status were associated with histoplasmosis incidence. This study highlights that the incidence of histoplasmosis is relatively high and therefore further studies are important to be conducted in Indonesia that has a high MDR-TB cases.

Observation of Malaria Treatment with Dihydroartemisinin-Piperaquine Combination at Primary Health Care

Objective: Dihydroartemisinin-Piperaquine (DHP) combination is the first-line treatment for uncomplicated malaria in Indonesia and has been used since 2010. This study was conducted to determine the efficacy of DHP combination for uncomplicated malaria treatment in a community-based evaluation. Methods: Recruitment was done by active or passive case detection. All uncomplicated malaria patients were treated with DHP once a day, for 3 days, administered orally (as is done in primary health care). Patients were followed up until day 28 post-treatment. The primary end point was a 28-day cure rate. Results: In this study, 484 subjects were screened through active and passive cases detection. A total of 45 subjects infected by P. vivax and 2 subjects infected by P. falciparum agreed to participate through written informed consent. There was no difference between clinical malaria and asymptomatic malaria in all analyzed characteristics. One patient had a D3 parasite density greater than 25% D0, although no parasites were found on the following day (D4). This study found 46 patients (97.9%) who had adequate clinical and parasitological responses. No adverse event was reported during the follow up of this study. Conclusion: DHP was effective, safe, and well tolerated in the treatment of uncomplicated malaria at primary health care.

The Effectivity of Ethanolic Extract from Papaya Leaves (Carica papaya L.) as an Alternative Larvacide to Aedes spp.

BACKGROUND: Dengue haemorrhagic fever (DHF) is a disease found in most tropical and subtropical regions of the world, including Indonesia. One of the problems of vector control programs is insecticides resistance to Aedes spp. AIM: The objective of this study is to determine the effectiveness of an alternative larvacide using papaya leaves (Carica papaya L). METHODS: To obtain an ethanolic extract of C. papaya leaf (EECP), the dried of C. papaya leaf was macerated with ethanol 70%. Phytochemical compounds were screened qualitatively. Twenty-five larvae were entered into each cup that had been mixed with five concentrations of EECP i.e., EECPI (100-), EECPII (150-), EECPIII (200-), EECPIV (250), EECPV (300 ppm), 1% of Temephos (T), and water (A). Alkaloid carpain, saponin, flavonoid, tannin, glycosides and triterpenoid/steroid were traced in EECP. The mortality of larvae at 180, 360, 1440 and 2880 minutes were observed. The lethal concentration (LC50) and lethal time (LT50) were measured. Probit analysis was used to determine the concentration of killing larvae. RESULTS: The mortality of larvae was found at 360 minutes only in EECPV. Then after 1440 minutes, all extracts shown the increasing of larvae mortality. LC50 and LT50 values were 215,96 ppm and 2,369 minutes of each. CONCLUSION: EECP has larvicidal activity to Aedes spp.
