Immunological recovery after measles.

Twenty-two children with measles were studied at the stage of the rash and 6 weeks later, and results compared with matched controls. The total lymphocyte count and lymphocyte subpopulations with T- and B-cell markers and those with absence of both markers (null cells) were significantly below control levels in the acute phase. At 6 weeks the B-cell and null-cell counts were still significantly diminished. The function of T cells assessed by 14C uptake of phytohaemagglutinin-stimulated lymphocytes and the delayed skin hypersensitivity reaction to dinitrochlorobenzene was impaired during the acute stage, and this persisted for 6 weeks. Over the 6 weeks of study there was a small but significant rise in serum IgG, IgM and complement factors.

Immunoparesis and outcome in measles.

In five children with measles who subsequently died and in one with measles in whom chronic bronchopneumonia developed (group A), immunosuppression was more pronounced during the acute rash (i.e., 3-20 days before death) than in six children with measles who recovered (group B). The absolute total lymphocyte-count (T and B cells) was significantly lower in group A. Mean serum-C3 was also lower in group A than in group B. There were no significant differences between the two groups for other complement factors or for serum-immunoglobulins. The mean phytohaemagglutinin stimulation index (S.I.) for lymphocytes from patients in group A resembled that in group B, although the S.I. in both groups was significantly lower than that in healthy controls. S.I.S were lowest in two patients who died. Counts of total white cells, neutrophils, null cells, and those with both B and T cell markers were not significantly different in groups A and B. The total lymphocyte-count (mean 2117 +/- S.E.M. 375 cells/mm3) in a further nineteen patients with measles who had died, studied retrospectively, was significantly lower than that (4487 +/- 540 cells/mm3) in twenty-seven patients with measles who recovered.

Fatal adenovirus pneumonia: Clinical and pathological features.

A review of autopsies of 107 young children with pneumonia showed that 15 children (14%) had adenovirus infections, the diagnosis being based on characteristic histopathological and ultrastructural features in the lungs. Eleven (73%) of the cases of adenovirus infection followed on measles infection, and it is suggested that some became infected with adenovirus after admission to hospital. A review of clinical aspects revealed no unique features. Histopathological examination of tissues showed a common picture of necrotising bronchopneumonia, with minor degrees of rental tubular damage, infiltrates of large mononuclear cells in spleen and nodes, and an absence of lymphoid germinal centres. On light microscopy, "rosette" and "smudge" cells were seen in these cases, and two patterns of virus particle distribution in infected cells were seen ultrastructurally. It is postulated that "smudge" cells contain numerous crystalline viral arrays.
