The Sakita-Miwa classification (also known as the Sakita-Fukutomi classification) is a widely used endoscopic staging system for peptic ulcers, primarily gastric and duodenal ulcers. It categorizes the life cycle of an ulcer into three major stages—Active (A), Healing (H), and Scarring (S)—each subdivided into two sub-stages to provide a total of six steps in the healing process. 1. Active Stage (A)
The emergence of the Sakitamiwa virus (SKTV), a novel paramyxovirus transmitted by the Aedes sahari mosquito, has necessitated the development of a standardized clinical staging system. The Sakitamiwa Classification, proposed by the Joint East African Center for Emerging Zoonoses (JEACEZ) in 2021, provides a five-tier framework (Stage 0 through Stage IV) to stratify patients based on viral load, endothelial dysfunction, and multiorgan involvement. This article explores the history, clinical criteria, and prognostic utility of the Sakitamiwa Classification, offering clinicians a practical guide for diagnosis, treatment allocation, and vaccine triage. sakitamiwa classification
Unlike the pulmonary classification in adults, TB in children presents differently due to the inability of children to expectorate sputum effectively and the higher likelihood of disseminated disease. This classification helps clinicians determine prognosis and treatment intensity. Active Stage (A) The Sakitamiwa Classification: A New
: The ulcer is deep with a thick white or yellow coating (slough). The surrounding mucosa is edematously swollen (swelling from fluid), and no regenerating epithelium (new skin) is visible. Unlike the pulmonary classification in adults, TB in
The body begins to repair the tissue, and the ulcer significantly reduces in size. Intestinal Research H1 (Healing-1):
The Sakita-Miwa classification is a standardized endoscopic grading system used primarily by gastroenterologists to assess the life cycle and healing stages of peptic ulcers (both gastric and duodenal). Developed by Japanese researchers Sakita and Miwa, it divides the progression of an ulcer into three main stages—Active (A), Healing (H), and Scarring (S)—each further subdivided into two substages.
Critics of the Sakitamiwa Classification point to three unresolved issues:
