Human herpesvirus 8 genotype E in patients with Kaposi sarcoma, Peru.

To determine human herpesvirus 8 (HHV-8) K1 genotypes in patients with Kaposi sarcoma (KS) from Peru, we characterized HHV-8 in 25 KS biopsy samples. Our findings of 8 A, 1 B, 14 C, and 2 E subtypes showed high HHV-8 diversity in these patients and association between E genotype and KS development.

A comparison of the prevalence of metabolic syndrome and its components in high and low altitude populations in peru.

Background: Prevalence of the metabolic syndrome has been described in populations with ethnic and cultural differences. The aim of this study was to determine the prevalence of the metabolic syndrome on a population from the Andes Mountains of Peru and compare it to a sea-level population.

Methods: A cross-sectional study of subjects aged 30 years old or more from the high-altitude population of San Pedro de Cajas (SPC) (13,450 feet) and the sea-level population of Rimac (331 feet) was done.

Classic Kaposi's sarcoma presenting in the oral cavity of two HIV-negative Quechua patients.

Traditionally, classic KS lesions have a general distribution, often involving the skin of the feet and legs, and to a lesser extent, that of the hands, arms, and trunk. Oral involvement is a rare manifestation. Initial oral involvement is an even rarer occurrence.

Human herpesvirus-8 in Peruvian blood donors: a population with hyperendemic disease?

Serum samples from 128 blood donors were tested for antibodies specific for human herpesvirus-8 by an immunofluorescence assay that detects antibodies against mainly lytic antigens. An overall seroprevalence of 56.25% was found (male donors, 54.

Lipid profile, waist circumference, and body mass index in a high altitude population.

Some studies have found different distribution patterns for the lipid profile of high altitude populations, having found the majority of them a more favorable one in these subjects. The objective of this study is to describe the lipid profile of a high altitude population and relate it to the waist circumference, body mass index, gender, and age. A descriptive study was done in an adult population, 30 yr old and above, of the town of San Pedro de Cajas (SPC), Peru, located at 4100 m (13,450 ft) above sea level.

Is classic Kaposi's sarcoma endemic in Peru?: report of a case in an indigenous patient.

Kaposi's sarcoma (KS) has been classified in four clinical variants (classic or Mediterranean; endemic or African; epidemic or AIDS-related; iatrogenic or immunosuppression-related). Human herpesvirus 8 (HHV-8), has been found in all these variants. We herein discuss the unusual presentation of a 53-year-old indigenous patient with purplish-brown nodular lesions on lower extremities, and miliary tuberculosis.

Characteristics of Castleman's disease in Peru.

Background: Castleman's disease (CD) is a very rare disorder of unknown etiology that is characterized by masses of lymphoid tissue.

Methods: The records of all patients with a histological diagnosis of CD who were seen at the Hospital Nacional Cayetano Heredia and the Instituto Nacional de Enfermedades Neoplásicas between 1985 and 2003 and 1985 and 2001, respectively, were reviewed.

Results: The study included 10 patients.

[Classic Kaposi Sarcoma in jejunum: case report].

Classic Kaposi Sarcoma (KS) may affect mucosa, especially oral cavity and any part of the gastrointestinal tract. It has been reported in 10% of patients with classic KS. We report a 35-year old male patient with primary classic KS in jejunum that presented with bowel obstruction.

Epidemiological and clinical characteristics of classic Kaposi's sarcoma in Peru.

Background: Classic Kaposi sarcoma (KS) occurs predominantly among the elderly, with predominance among Jews, Italians, and Greeks. Classic KS has been seen relatively frequently in Peru.

Objective: Our purpose was to outline the epidemiological and clinical profile of classic KS in Peru.

Epidemiology and clinical characteristics of classic Kaposi's sarcoma, seroprevalence, and variants of human herpesvirus 8 in South America: a critical review of an old disease.

Objective: To review the current South American literature on classic Kaposi's sarcoma (KS) and human herpesvirus 8 (HHV-8), and point the way for studies that still need to be performed.

Materials And Methods: The authors performed an exhaustive search in LILACS, SCIELO and PUBMED databases for classic KS and HHV-8 in South America. The relevant material was evaluated and reviewed.
