BACKGROUND: Bacterial gastroenteritis is a disease in the tropics in the form of inflammation of the stomach and intestines due to several bacteria, such as Salmonella, Campylobacter, Shigella, Escherichia coli, Vibrio, Yersinia, and Listeria with symptoms of diarrhea without or with vomiting and frequent fever. Gastroenteritis is a global disease with the highest prevalence in the agricultural community, especially farmers and fishermen. AIM: This research is to determine the potential of leaf and seed extract Moringa oleifera as an alternative therapy for bacterial gastroenteritis. METHODS: A literature review approach derived from the analysis and synthesis of various related references is used. The author selects journals full text and books published in the last ten years maximum through several databases, namely PubMed, Google Scholar, ScienceDirect, and Cochrane with the keywords: diarrhea, gastroenteritis, antibacterial, antiulcer, anti-inflammation, and M. oleifera. RESULTS: Seed and leaf extract M. oleifera played a role in preventing some of the effects of the pathogenesis of diarrhea due to bacterial infection. Methanol, N-hexane, ethyl acetate, flavonoids, phenols, saponins, alkaloids, tannins, and steroids from seed and leaf extract M. oleifera have antibacterial effects. The content of quercetin has an anti-inflammatory effect. The content of tannins, flavonoids, and alkaloids has antidiarrheal activity. The content of ethanol and tannins has an antiulcer effect. This potential can help cure patients with bacterial gastroenteritis. CONCLUSION: Leaf and seed extract of M. oleifera has good antibacterial, anti-inflammatory, antiulcer, and antidiarrheal potential for the treatment of bacterial gastroenteritis.

ABSTRAK   Gastroenteritis bakteri adalah salah satu penyakit di daerah tropis berupa peradangan lambung dan usus akibat beberapa bakteri, seperti Salmonella, Campylobacter, Shigella, E. coli, Vibrio, Yersinia, dan Listeria dengan gejala diare tanpa maupun disertai muntah, dan sering demam. Gastroenteritis menjadi penyakit global dengan prevalensi tertinggi pada komunitas agrikultur terutama petani dan nelayan. Penelitian ini bertujuan untuk mengetahui potensi ekstrak daun dan biji Moringa oleifera sebagai alternatif terapi gastroenteritis bakteri. Metode penulisan jurnal menggunakan pendekatan tinjauan pustaka yang berasal dari analisis dan sintesis berbagai referensi terkait. Penulis memilih jurnal full text dan buku tahun terbit maksimal sepuluh tahun terakhir melalui beberapa database, yaitu PubMed, Google Scholar, Science Direct, dan Cochrane dengan kata kunci: diare, gastroenteritis, dan Moringa oleifera. Ekstrak biji dan daun Moringa oleifera berperan dalam mencegah beberapa efek dari patogenesis diare akibat infeksi bakteri. Metanol, N-hexane, etil asetat, flavonoid, fenol, saponin, alkaloid, tanin, dan steroid dari ekstrak biji dan daun Moringa oleifera memiliki efek antibakteri. Kandungan quercetin memiliki efek antiinflamasi. Kandungan tanin, flavonoid, dan alkaloid memiliki aktivitas antidiare. Kandungan etanol dan tanin memiliki efek antiulkus. Potensi tersebut dapat membantu penyembuhan penderita gastroenteritis bakteri.

The COVID-19 pandemic is still a global health problem, and the lack of effective and efficient treatment standards is one of the causes of the high morbidity and mortality rates. One approach often used in various cases of COVID-19 is convalescent plasma therapy. The administration of convalescent plasma is one of the treatment options that are often used in cases of COVID-19 with mild, moderate, severe, chronic, and critical symptoms. The article review aims to analyze how convalescent plasma transfusion in various cases of COVID-19 can prevent death and improve clinical outcomes. The PRISMA flowchart is applied to filter the literature that meets the inclusion criteria: published articles with experimental or observational research discussing the use of convalescent plasma in COVID-19 patients; published January 2020 - March 2021. We conducted article searches through PubMed, Google Scholar, and Science Direct. Assessment of the quality of the articles using the EPHPP form, and we chose ten articles. The results of the qualitative analysis prove that convalescent plasma administration in various COVID-19 cases significantly reduces viral load, clinical improvement and prevents death in mild, moderate, and severe COVID-19s, but for terminal or critical cases, it does not show significant results. The success rate of convalescent plasma therapy is determined by the high antibody titer in plasma donors, the distance between its administration and the onset of symptoms, and the patient's baseline condition before plasma administration. Based on these results, further research is needed to determine the standard dose and method of administration of convalescent plasma referring to the varied baseline conditions of patients.
