Similarities Between Internal Variable Lesions in African Swine Fever (ASF) and Kaposi's Sarcoma
Overview
Both African Swine Fever (ASF) in pigs and Kaposi's Sarcoma (KS) in humans are characterized by lesions with marked variability in their internal distribution, severity, and appearance. Comparing the pathology of these diseases illuminates fundamental similarities in the variable and multi-organ nature of their internal lesions.

1. Lesion Distribution and Variability
African Swine Fever:

Lesions are highly variable depending on the virulence of the ASF virus and the disease course.

Internal organs commonly affected include spleen, lymph nodes, kidneys, liver, lungs, and heart.

Lesions can range from minimal to severe; they may occur as hemorrhages, infarctions, and swelling, and their location and intensity differ between individual pigs and disease stages.

Kaposi's Sarcoma:

KS also presents with variable internal lesions, affecting not only the skin but also organs such as the lymph nodes, lungs, gastrointestinal tract, liver, and spleen.

Lesion distribution is unpredictable and can occur in multiple sites simultaneously or progress unevenly.

Lesions vary in size, shape, and number; they may be inconspicuous or cause substantial organ dysfunction depending on their location.

2. Gross and Histopathological Features
Feature African Swine Fever Kaposi's Sarcoma
Types of Lesions
Hemorrhages, infarction, swelling, necrosis Nodules, plaques, hemorrhages, spindle cell proliferation
Organs Involved
Spleen, lymph nodes, kidneys, heart, liver, lungs Lymph nodes, lungs, liver, spleen, GI tract
Nature of Lesions
Highly variable, even within a single animal Highly variable, even within a single patient
Severity/Extent
Ranges from none to extensive organ involvement Ranges from isolated minor lesions to extensive internal disease
Pathogenesis
Vascular injury, immune cell infiltration Vascular/endothelial proliferation, possible hemorrhage
3. Influence of Host and Pathogen Factors
Variation in Lesions Due to Host Factors:

Chronic, subacute, and acute forms of ASF each show different lesion patterns, and not all pigs exhibit the same spectrum of internal damage.

In KS, the degree of immunosuppression or co-morbid disease (like HIV) influences lesion development, with some patients experiencing widespread internal involvement while others may have minimal disease.

Influence of Viral Strain/Type:

ASFV strains of differing virulence yield varied lesion expression in pigs.

KS lesion variability is partially explained by the host immune status and the biology of the HHV-8 virus.

4. Pathophysiological Parallels
Vascular Damage and Involvement:

Both diseases involve significant vascular pathology.

ASF often causes vascular leakage, hemorrhages, and edema in multiple organs.

KS is essentially a vascular tumor, where abnormal blood vessel proliferation can cause bleeding, obstruction, and localized edema in internal organs.

5. Clinical Implications
Variable internal lesion patterns in both ASF and KS complicate diagnosis and disease progression assessment.

Both diseases can result in subclinical, mild, or severe multi-organ involvement; patients/pigs may be asymptomatic or suffer fatal complications depending on lesion severity and organ systems affected.

Conclusion
The internal lesions of ASF in pigs and Kaposi's Sarcoma in humans are fundamentally similar in three main ways:

Both are highly variable in distribution, severity, and morphology.

Both primarily affect internal vascular and lymphoid organs and may range from mild to severe within the same population.

Lesion variability in both diseases is influenced by pathogen characteristics and host factors, complicating clinical diagnosis and prognostication.

A satirical story about in which AIDS activists get involved in promoting and defending science that turns out to be totally wrong and backfires on them

" A new study finds that prior herpesvirus infections are linked to a faster age-related increase in blood biomarkers associated with dementia, even in cognitively healthy women. Researchers measured five key biomarkers in 167 women and found that seropositivity for HHVs doubled the rate of biomarker accumulation compared to those without prior infection. The strongest viral associations were seen for Epstein-Barr virus and HHV6, with amyloid-beta and phosphorylated tau levels most affected. These findings support the hypothesis that chronic viral infections may accelerate neurodegeneration and raise dementia risk independently of genetic factors."
