AIM: To evaluate the presentation and course of @entity631 ( @entity631 ), which has increased dramatically in Armenia after serious deterioration in the living conditions. STUDY DESIGN: Observational study, based on case notes, of a large homogeneous group of @entity1 hospitalised for @entity631 at one centre over a five year period (1992-6). @entity1 : 474 @entity1 aged < 16 years with a diagnosis of @entity631 . RESULTS: The annual number of @entity1 increased tenfold from 19 (average 1992/3) to 196 in 1995. Sixty two per cent were in the age group 4-9 years and 65% were @entity1 . @entity1729 , scarlet @entity221 , and @entity272 preceded @entity631 in 51%, 23%, and 13%, respectively. All @entity1 had haematuria (93% gross), 84% had @entity4 , and 72% had @entity101 . C3 was initially decreased in 95% of the @entity1 examined. Renal function was impaired (serum @entity1011 > 100 mumol/l) in 29%. Four @entity1 with @entity177 had crescentic @entity631 at biopsy; of these, three required temporary haemodialysis. Main extrarenal complications were @entity712 (10%) and @entity410 (3%). One @entity1 died and five (3%) did not recover completely. CONCLUSIONS: @entity631 in @entity1 is associated with considerable initial morbidity, and long term outcome is not uniformly benign. Outbreaks of @entity631 may occur anytime in countries such as Armenia that are suffering from a sudden decline in socioeconomic conditions.

An epidemic of XXXX in Armenia.
