Early lymphopenia in burned children with and without the toxic shock syndrome.
The white cell count (WCC) response to thermal injury in children in week 1 postburn has been investigated in a prospective study of 33 patients. Two of these patients developed the toxic shock syndrome (TSS) and, together with seven previously diagnosed cases of the TSS, were studied as a separate group. The WCC response in the non-TSS (control) patients was compared with the response observed in the TSS group. In all patients there was an initial leucocytosis followed by a fall in WCC to a nadir between days 2 and 4. The nadir was significantly lower in the TSS group than that observed in the control group. A rise in the WCC was observed over the following 3-4 days in both groups. In the control group the changes in the WCC were mainly attributable to changes in the granulocyte count with little change in the lymphocyte count. There were similar changes in the granulocyte count in the TSS group but, in contrast to the control group, the lymphocyte count fell, to below the normal range, on day 3. The lowest lymphocyte count observed in the TSS group was significantly lower than that seen in the control group. The observation of a profound fall in the total WCC, granulocytes, and in particular the lymphocytes, between days 2 and 4 are additional factors that may help with the diagnosis of TSS.
