Overview
The exact pathogenesis of [disease name] is not fully understood.
OR
It is thought that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
OR
[Pathogen name] is usually transmitted via the [transmission route] route to the human host.
OR
Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
OR
[Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
OR
The progression to [disease name] usually involves the [molecular pathway].
OR
The pathophysiology of [disease/malignancy] depends on the histological subtype.
Pathophysiology
Pathogenesis
- Whipple's disease is a rare bacterial systemic infection caused by Tropheryma whipplei.[1]
- Tropheryma whipplei is a periodic acid-Schiff stain positive, gram-positive bacillus of actinomycetes family.[2]
- The bacteria lives in soil and wastewater. Farmers and everyone who has any contact with contaminated soil and water are in high risk of the infection.
- It is transmitted through oro-oral and feco-oral routes. The poor sanitation is associated with T. whipplei infection. [3]
- It is believed that human being is the only reservoir for this bacteria.
- It invades primarily intestines and then every other organ including the heart, brain, joints, skin, lungs and the eyes.
- Tropheryma whipplei infection has four different manifestations: acute infection, the classic Whipple’s disease, asymptomatic carrier state[4], and localized chronic infection.
- It is believed that host immunologic response to the microorganism plays an important role on the clinical manifestation of the disease.[5]
- Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
- [Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
- The progression to [disease name] usually involves the [molecular pathway].
- The pathophysiology of [disease/malignancy] depends on the histological subtype.
Genetics
- [Disease name] is transmitted in [mode of genetic transmission] pattern.
- Genes involved in the pathogenesis of [disease name] include [gene1], [gene2], and [gene3].
- The development of [disease name] is the result of multiple genetic mutations.
Associated Conditions
Gross Pathology
- On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
Microscopic Pathology
- On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
