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
Physiology
The normal physiology of [name of process] can be understood as follows:
Pathogenesis
- The exact pathogenesis of [disease name] is not completely understood.
OR
- It is understood that G6PD deficiency is the result of reduced Glucose-6-phosphate dehydrogenase enzyme levels. G6PD deficiency is an X-linked disorder. It is the most common enzymatic disorder of red blood cells. Glucose-6-phosphate dehydrogenase enzyme oxidize glucose-6-phosphate to 6-phosphogluconolactone in pentose phosphate pathway ( HMP shunt). Glucose-6-phosphate dehydrogenase enzyme also reduces nicotinamide adenine dinucleotide phosphate (NADP) to NADPH. NADPH is an important cofactor in glutathione metabolism against oxidative injury in RBC.Reduced glutathione (GSH) convert to oxidized glutathione (GSSG) by glutathione peroxidase enzyme that prevent oxidant accumulation. Glutathione reductase catalyzes the reduction of GSSG to GSH by NADPH. In G6PD deficiency, oxidative stresses can denature hemoglobin and intravascular hemolysis in RBC can happen. Infection, some meication and foods with high level of convicine, vicine, divicine and isouramil such as fava beans can cause oxidative stress. Spleen is the organ for sequesteration damaged RBC. The hemoglobin is metabolized to bilirubin and cause jaundice.
- [Pathogen name] is usually transmitted via the [transmission route] route to the human host.
- 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
G6PD deficiency is transmitted in x-linked disorder pattern.
OR
Genes involved in the pathogenesis of G6PD deficency include:
- [Gene1]
- [Gene2]
- [Gene3]
OR
The development of [disease name] is the result of multiple genetic mutations such as:
- [Mutation 1]
- [Mutation 2]
- [Mutation 3]
Associated Conditions
Gross Pathology
On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
Microscopic Pathology
On microscopic histopathological analysis, , Heinz bodies can be visualized as a result of denatured hemoglobin in peripheral blood smears with supravital staining. processed with supravital staining (Heinz body prep).
