"Meningkatnya penggunaan narkoba (narkotika, psikotropika dan berbahaya lainnya) di dunia, berdampak pada penyalahgunaan Methamphetamin (METH) khususnya di Indonesia. Efek METH dapat menginduksi neurotoksik, dimana terjadi kerusakan pada saraf terminal dopaminergik, serotonergik, apoptosis neuron, astroglia dan aktivasi mikroglia yang mengarah pada respon peradangan saraf di dalam otak. Studi menunjukkan efek NAC yang signifikan dalam memperbaiki TNF-α dan IL-6 pada fase infeksi akut atau kronis memotivasi pelaksanaan penelitian untuk mengevaluasi perubahan kadar IL-6 dan TNF-α pada pasien ketergantungan METH yang mengalami withdrawal pada kelompok yang mendapatkan terapi N- asetilsistein.Penelitian ini menggunakan bahan biologis tersimpan (serum), untuk mengetahui kadar IL-6 dan kadar TNF-α sebagai indikator neuroinflamasi pada pasien dengan ketergantungan METH yang mendapatkan terapi NAC (n=30) atau Placebo (n=30) selama 30 hari (cross-sectional). Penelitian dilakukan di Laboratorium Farmakologi Kinetik FKUI Salemba, Jakarta Pusat dan waktu penelitian pada bulan Agustus 2022 sampai bulan November 2022 dengan menggunakan metode ELISA. Hasil penelitian didapatkan 15 sampel yang terukur dan hanya 7 sampel yang dapat dianalisis (NAC-Placebo, Pre-Post Intervensi). Hasil mean TNF-α (Pre NAC) = 78.403 (pg/ml) ± 108,02, dan mean TNF-α (Post NAC) = 55,3176 (pg/ml) ± 75,15. Hasil IL-6 didapatkan pre NAC= 13,52 pg/ml, dan post NAC= 7,57 pg/ml. Kesimpulan penelitian adalah kadar IL-6 pada kelompok yang mendapatkan NAC mengalami penurunan dan kadar TNF-α pada kelompok yang mendapat NAC mengalami penurunan. Saran untuk penelitian selanjutnya diperlukan sampel baru dengan subyek yang lebih banyak dengan parameter inflamasi lainnya, dan kit-reader yang sensitif untuk mendapatkan efek potensial anti-inflamasi NAC pada subyek ketergantungan METH.

The increasing use of drugs (narcotics, psychotropics and other dangerous drugs) in the world has had an impact on the abuse of Methamphetamine (METH), especially in Indonesia. The effects of METH can induce neurotoxicity, where there is damage to dopaminergic, serotonergic nerve terminals, neuronal apoptosis, astroglia and activation of microglia which leads to a neuroinflammatory response in the brain. The study shows the significant effect of NAC in improving TNF-α and IL-6 in the acute or chronic phase of infection motivating the implementation of research to evaluate changes in IL-6 and TNF-α levels in METH-dependent patients experiencing withdrawal in the group receiving N-acetylcysteine ​​therapy .

This study used stored biological material (serum), to determine IL-6 levels and TNF-α levels as indicators of neuroinflammation in patients with METH dependence who received NAC therapy (n=30) or Placebo (n=30) for 30 days (cross -sectional). The research was conducted at the Kinetic Pharmacology Laboratory, FKUI Salemba, Central Jakarta and the research period was from August 2022 to November 2022 using the ELISA method.

The research results showed that 15 samples were measurable and only 7 samples could be analyzed (NAC-Placebo, Pre-Post Intervention). Results mean TNF-α (Pre NAC) = 78.403 (pg/ml) ± 108.02, and mean TNF-α (Post NAC) = 55.3176 (pg/ml) ± 75.15. IL-6 results showed that pre NAC= 13.52 pg/ml, and post NAC= 7.57 pg/ml. The conclusion of the study was that IL-6 levels in the group that received NAC decreased and TNF-α levels in the group that received NAC decreased. Suggestions for further research require new samples with more subjects with other inflammatory parameters, and sensitive kit-readers to obtain the potential anti-inflammatory effect of NAC in METH-dependent subjects."

"We reported here a rare case of a 62 year old male patient with obstructive jaundice due to bile duct tumor. The main clinical features were yellowish eye and skin, followed by pruritus and clay-colored stool. Ultrasonography showed common bile duct dilatation and without evidence of stones. Computed Tomography Scan of upper abdomen showed a mass which were thought of head of pancreas origin. Endoscopic Retrograde Cholangio Pancreatograph revealed tight narrowing of the distal bile duct to a malignant tumor. A stent was inserted to allow biliary drainage, A surgical plan for billio digestive anastomosis was rejected by the patient and family."

"Pembedahan masih menjadi standar emas terapi kuratif untuk obstruksi saluran empedu maligna, namun hanya 10-20% kasus yang dianggap dapat dioperasi. Oleh karena itu, terapi paliatif untuk menghilangkan rasa sakit, kolestasis, dan obstruksi saluran empedu, merupakan pengobatan utama bagi sebagian besar pasien. Perkembangan drainase bilier transhepatik perkutan dan drainase bilier endoskopi telah menghasilkan pengobatan invasif minimal untuk obstruksi bilier ganas, yang memiliki morbiditas dan mortalitas lebih rendah dibandingkan drainase bedah. Pilihan teknik drainase tergantung pada jenis tumor, lokasi obstruksi, serta ketersediaan tenaga ahli dan instrumentasi.

Surgery is still the golden standard of curative therapy for malignant biliary obstruction, but only 10-20% of cases considered resectable. Therefore, palliative therapy to relieve pain, cholestasis, and biliary obstruction, is the main treatment for most patients. The development of percutaneous transhepatic biliary drainage and endoscopic biliary drainage had brought about minimally invasive treatment for malignant biliary obstruction, which had lower morbidity and mortality than surgical drainage. The choice of drainage technique depends on type of tumor , site of obstruction, also the available expert and instrumentation."

"Endometriosis merupakan penyakit ginekologi umum yang dipicu terjadinya peradangan kronis yang ditandai dengan produksi beberapa sitokin pro-inflamasi, salah satu yang terbanyak yaitu TNF-α. Di sisi lain, sitokin anti-inflamasi, seperti IL-10, dapat mengakhiri proses inflamasi berlanjut ini. Propolis adalah bahan bioaktif alami produk lebah, sebagai imunomodulator dan efek anti-inflamasi yang dapat menekan proliferasi sel-sel patologis. Penelitian ini bertujuan untuk menentukan pengaruh pemberian propolis terhadap tumor necrosis factor alpha dan interleukin 10. Penelitian ini menggunakan desain uji klinis dengan alokasi acak dan double-blinded. 24 wanita dengan terapi Levonorgestrel (LNG) karena endometriosis secara acak ditugaskan untuk menerima propolis yang mengandung 17,5 mg flavonoid per tetes atau plasebo. Intervensi diberikan dua kali sehari, pada pagi dan malam hari, dengan dosis 1 tetes/10 kg berat badan (kgBB) per kali.

Endometriosis is a common gynecological disease triggered by chronic inflammation characterized by the production of several pro-inflammatory cytokines, one of which is TNF-α. On the other hand, anti-inflammatory cytokines, such as IL-10, can end this ongoing inflammatory process. Propolis are natural bioactive ingredients contained in bee products, as immunomodulators and anti-inflammatory effects that can suppress the proliferation of pathological cells. This study aimed to determine the effect of propolis supplementation on tumor necrosis factor alpha and interleukin 10. This study used clinical trial design with random allocation and double- blinded. 24 women with Levonorgestrel (LNG) therapy due to endometriosis were randomly assigned to receive propolis-contained 17.5 mg of flavonoids per drop or placebo. The intervention given two times a day,in the morning and at night, with a dose of 1 drop /10 kg body weight (kgBW) per time. Blood samples and nutritional assessment were taken at the first time of visit and 30 days thereafter. The results showed that the levels of tumor necrosis factor alpha and interleukin 10 did not differ significantly between the two groups (p>0.05). Tumor necrosis factor alpha levels experienced a greater decrease in the propolis group by 4.17 (44.36-50.05) pg/mL compared to the placebo group. IL-10 levels showed an increase of 344.94 after 30 days of intervention. The administration of propolis supplementation did not result in significant changes in the levels of Tumor Necrosis Factor Αlpha and Interleukin 10 during the 30- day intervention period."

"Latar Belakang: Panjang interval QTc dipengaruhi oleh berbagai faktor, salah satunya oleh inflamasi. Pada pasien COVID-19 sering terjadi badai sitokin sehingga menyebabkan peningkatan signifikan dari sitokin inflamasi, termasuk interleukin 6. Peningkatan interleukin 6 menyebabkan perubahan pada kanal ion kardiomiosit sehingga menyebabkan pemanjangan interval QTc yang berisiko aritmia.Tujuan: Mengetahui korelasi dengan melihat beda rerata kadar interleukin 6 dan panjang interval QTc, nilai titik potong kadar interleukin 6 terhadap panjang interval QTc > 500 ms dan kekuatan kadar interleukin 6 dalam menilai risiko aritmia ventrikular.Metode: Penelitian ini menggunakan desain studi potong lintang dengan mengambil data sekunder rekam medik pasien COVID-19 yang menjalani rawat inap di RSCM Kiara sejak November 2020 hingga Maret 2021. Pada penelitian ini dilakukan analisis bivariat menggunakan uji Spearman. Selanjutnya dilakukan analisis terhadap beda rerata kadar interleukin 6 pada kelompok subyek dengan panjang interval QTc > 500 ms dan kelompok subyek dengan panjang interval QTc normal. Dilakukan analisis dengan Receiver Operating Curve (ROC) untuk melihat Area under curve (AUC) dan menentukan titik potong kadar interleukin 6 terhadap panjang interval QTc > 500 ms.Hasil: Pada penelitian ini didapatkan korelasi kadar interleukin 6 dan panjang interval QTc (r=0,72). Median kadar interleukin 6 pada kelompok subyek dengan interval QTc > 500 ms yaitu 99,36 pg/ml sedangkan pada kelompok subyek dengan interval QTc normal yaitu 19,51 pg/mL. Didapatkan AUC=0,852 untuk menentukan titik potong kadar interleukin 6 terhadap panjang interval QTc > 500 ms dengan nilai 59 pg/ml, dengan sensitivitas 80,6% dan spesifisitas 80%. Kejadian aritmia ventrikular tidak ditemukan sehingga tidak dapat dilakukan analisis untuk menilai kekuatan kadar interleukin 6 untuk menentukan risiko aritmia ventrikular.Kesimpulan: Terdapat korelasi kadar interleukin 6 dan panjang interval QTc dengan beda rerata kadar interleukin 6 pada subyek dengan interval QTc > 500 ms 5 kali lebih besar dibandingkan kelompok subyek dengan panjang interval QTc normal.

Background: The length of the QTc interval is influenced by various factors, one of which is inflammation. In COVID-19 patients, cytokine storms often occur, causing a significant increase in inflammatory cytokines, including interleukin 6. An increase in interleukin 6 can cause changes in the ion channels of cardiomyocytes, which can lead to prolonged QTc interval which is at risk of arrhythmias.

Objective: Knowing the correlation by looking at the differences in interleukin 6 levels and the length of the QTc interval, the cut-off value of interleukin 6 levels to the length of the QTc interval > 500 ms and the strength of interleukin 6 levels in assessing the risk of ventricular arrhythmias.

Method: This study used a cross-sectional study design by taking secondary data from the medical records of COVID-19 patients who were hospitalized at RSCM Kiara from November 2020 to March 2021. In this study, a bivariate analysis was carried out using the Spearman test. Furthermore, an analysis of the mean difference in interleukin 6 levels was carried out in the subject group with a QTc interval length> 500 ms and the subject group with a normal QTc interval length. Analyzes were performed using the Receiver Operating Curve (ROC) to see the area under curve (AUC) and determine the interleukin 6 cutoff point for the QTc interval length> 500 ms.

Result: The correlation between interleukin 6 levels and the length of the QTc interval (r=0.72) was found. The median level of interleukin 6 in the group of subjects with a QTc interval > 500 ms was 99.36 pg/ml while in the group of subjects with a normal QTc interval it was 19.51 pg/mL. AUC = 0.852 was obtained to determine the cut-off point for interleukin 6 levels to the QTc interval length > 500 ms with a value of 59 pg/ml, with a sensitivity of 80.6% and specificity of 80%. The incidence of ventricular arrhythmias was not found so that an analysis could not be performed to assess the power of interleukin 6 levels to determine the risk of ventricular arrhythmias.

Conclusion: There is a correlation between levels of interleukin 6 and the length of the QTc interval. The mean difference of interleukin 6 levels in subjects with QTc intervals> 500 ms was 5 times greater than those in groups of subjects with normal QTc interval lengths. The level of interleukin 6 59 pg / mL was determined as the cutoff value for the QTc interval length> 500 ms."
