Prehistoric juvenile rheumatoid arthritis in a precontact Louisiana native population reconsidered

A possible case of juvenile idiopathic arthritis from Renaissance Lucca (Tuscany, central Italy)

OBJECTIVE

The skeletal remains of a young individual (Guinigi US 1278) are described and a differential diagnosis is performed to determine the potential etiology of bone alterations.

MATERIALS

Archaeological excavations conducted at the private funerary chapel of the upper class members of the Guinigi family (14th-17th centuries AD) of Lucca (Tuscany, central Italy) brought to light the fragmented human skeletal remains of a young individual (Guinigi US 1278) with pathological osseous modifications.

METHODS

Morphological and radiological analyses were followed by differential diagnosis.

RESULTS

Guinigi US 1278 was a non-adult aged 16-20 years, who exhibited florid skeletal alterations in the form of vertebral fusion and extensive subchondral bone changes of the small and large joints of the appendicular skeleton. The severity of the resorptive process in the peripheral joints, as well as vertebral fusion, indicates a long-standing inflammatory process.

CONCLUSIONS

The features and the distribution of the skeletal lesions of Guinigi US 1278 are highly consistent with a form of juvenile idiopathic arthritis (JIA), leading to irreversible phenomena such as subchondral erosive lesions and axial ankylosis, with impairment of the gait and neck movements.

SIGNIFICANCE

While abundant clinical literature on JIA is available, paleopathological studies are scarce. The possible case of JIA from Lucca provides a direct opportunity to examine the chronic course of rheumatic disease in young individuals in the absence of appropriate medical therapies in the antiquity.

SUGGESTIONS FOR FURTHER RESEARCH

Future molecular analyses might be able to identify specific alleles of the HLA region responsible for JIA subtypes.

Rheumatic disease in native american children: Opportunities and challenge

Rheumatic diseases are prevalent in Native American adults at rates five to seven times higher than those seen in the Caucasian population. Little, however, has been published concerning rheumatic diseases in Native American children. The authors' work in Oklahoma and with tribes on the northern Great Plains demonstrates high rates of childhood-onset rheumatic disease in this population. Familial disease is common, and large, multiplex kindreds showing strong founder effects are likely found within specific Native American tribes. However, a deeper understanding of the genetic and environmental triggers of rheumatic disease in Native Americans will require a respect and appreciation for the specific and unique cultural and social issues that impinge on research with Native Americans and other indigenous people.

'Lyme disease': ancient engine of an unrecognized borreliosis pandemic?

Unexpectedly we have found large numbers of chronically ill Borrelia burgdorferi PCR- and seropositive patients in Houston, Texas, a zoonotically 'non-endemic' area. In order to understand this finding prior to sufficient data availability, we chose to examine critically currently accepted but troublesome 'Lyme disease' concepts. Our method was to analyze each foundation 'Lyme disease' premise within the context of available medical and veterinary literature, then to reconstruct the disease model consistent with the preponderance of that data. We find the present conceptualization of the illness seriously truncated, with a high likelihood of two distinct but connected forms of human B. burgdorferi infection. The yet-unrecognized form appears to have a broader clinical presentation, wider geographic distribution, and vastly greater prevalence. We conclude that 'Lyme disease' currently acknowledges only its zoonosis arm and is a limited conceptualization of a far more pervasive and unrecognized infection state that must be considered a global epidemic.
