The natural history of XXXX in Kuwait: a prospective six year follow-up report.

@entity1 @entity4789 @entity2401 @entity6331
One hundred and twenty-six @entity1 with the @entity4789 were followed up prospectively for 6 years. Sixty-six @entity1 maintained regular secondary prophylaxis (regular group) and 60 were irregular (irregular group). Two recurrences developed in the regular group with a recurrence rate of 0.005/ @entity1 /year follow-up, and 71 recurrences developed in the irregular group with a recurrence rate of 0.2/ @entity1 /year follow-up. These findings demonstrate the effect of secondary prophylaxis in reducing the frequency of recurrences. The prevalence rate of @entity6331 in @entity1 who had @entity2401 in the initial attack was 42% in the regular group vs 70% in the irregular group (p less than 0.05). These findings demonstrate the deleterious effect of recurrences in the evolution of @entity6331 . The prevalence rate of @entity6331 in @entity1 who maintained regular secondary prophylaxis, was 42% in those @entity1 who had @entity2401 in the initial attack and 6% in those who had no @entity2401 (p less than 0.05). These findings demonstrate the prognostic significance of presence or absence of @entity2401 during the initial attack, in the subsequent evolution of @entity6331 . The prevalence rate of @entity6331 in the 66 @entity1 who maintained regular prophylaxis was 23%. Comparison of these data with those of similarly designed studies shows that the evolution of @entity6331 following the @entity4789 , seems to behave similarly in the tropics and subtropics as it did in temperate climates.
