Temporal arteritis in Puerto Rico Hispanics.

Area of Science:

• Rheumatology
• Epidemiology
• Internal Medicine

Background:

• Previous studies suggested temporal arteritis (TA) is rare in Hispanic populations, proposing a genetic protective factor.
• This perception lacked robust epidemiological data from Hispanic communities.

Purpose of the Study:

• To investigate the presence and characteristics of temporal arteritis in a Hispanic population in Puerto Rico.
• To compare findings with existing epidemiological data on non-Hispanic populations.

Main Methods:

• A descriptive, observational, retrospective study was conducted in southern Puerto Rico.
• Clinical charts of 11 Hispanic patients diagnosed with temporal arteritis (July 2002-March 2004) were reviewed.
• Data analysis included frequencies and percentages of symptoms, laboratory results, and demographic information.

Main Results:

• Temporal arteritis was confirmed in 11 Hispanic patients (8 female, 3 male; ages 70-90).
• Headache was the most common symptom, with fatigue, malaise, and visual disturbances also noted.
• Elevated ESR and C-reactive protein, along with positive biopsies, were statistically significant. Female-to-male ratio was 2.6:1, the lowest reported.
• Clinical and laboratory findings correlated with classic descriptions in non-Hispanic populations. Hypertension was a common comorbidity.

Conclusions:

• Temporal arteritis occurs in Hispanic populations, challenging previous assumptions of rarity.
• The clinical presentation and laboratory findings in this Hispanic cohort align with those observed in other ethnic groups.
• Further research is warranted to explore potential genetic or environmental factors influencing TA prevalence and presentation in diverse populations.
