Abstract INTRODUCTION: This study aimed to evaluate and compare with healthy control subjects the levels of indirect inflammatory markers such as mean platelet volume (MPV), platelet to lymphocyte ratio (PLR), and neutrophil to lymphocyte ratio (NLR) in adults and children with brucellosis. METHODS: White blood cell, neutrophil, lymphocyte, and platelet counts, and C-reactive protein (CRP) levels were retrospectively recorded for all participants. RESULTS: NLR and neutrophil counts were significantly higher in adult patients compared to those in pediatric patients. CONCLUSIONS: Indirect inflammatory markers such as NLR, PLR, MPV, red distribution width, and CRP levels may be helpful for follow-up of brucellosis.

Viral myositis associated with infections rarely may cause rhabdomyolysis. There is no any pediatric case with severe recurrent rhabdomyolysis triggered by infections in the literature. We reported a two-year-old boy who was hospitalized three times due to severe rhabdomyolysis associated with viral myositis in the winter months. This is the first child case presentation with severe rhabdomyolysis triggered by infections. Prednisolone and intravenous immunoglobulin treatments were ineffective in this case.

La miositis viral asociada a infecciones raramente produce rabdomiólisis. En las publicaciones científicas no se describe ningún caso pediátrico de rabdomiólisis grave recurrente inducida por infecciones. En este artículo presentamos el caso de un niño de sexo masculino de dos años de edad hospitalizado en tres ocasiones debido a rabdomiólisis grave asociada a miositis viral durante el invierno. Esta es la primera presentación de un caso pediátrico de rabdomiólisis grave inducida por infecciones. En este paciente, el tratamiento con prednisolona e inmunoglobulinas por vía i.v. fue ineficaz.
