A longitudinal investigation has been conducted into the cell-mediated immune responses of onchocerciasis patients after a single-dose treatment with ivermectin. Untreated patients tested for delayed cutaneous hypersensitivity (DCH) to seven recall antigens showed lower responses than infection-free control individuals (P less than 0.01), but 6 and 14 months after treatment DCH reactions increased to similar levels to those seen in the controls. The in vitro cellular reactivity to Onchocerca volvulus-derived antigen (OvAg) was reduced in untreated patients as compared with controls, and the lymphocyte blastogenic responses to OvAg and streptolysin-O clearly improved up to 14 months after treatment. Peripheral blood mononuclear cells (PBMC) from untreated patients produced IL-1 beta, tumour necrosis factor-alpha (TNF-alpha) and IL-6 in response to mitogenic stimulation with phytohaemagglutinin (PHA), only low levels of IL-1 beta, IL-2 and TNF-alpha in response to OvAg, but higher amounts of IL-4 and interferon-gamma (IFN-gamma) in response to OvAg than control individuals. After ivermectin treatment, the OvAg-induced production of IL-1 beta and TNF-alpha increased significantly 1 and 14 months after treatment. The PHA-induced production of IL-2 and IL-4 increased 1 month after treatment and remained significantly elevated until 14 months after treatment, whereas the OvAg-specific secretion of IL-2, IL-4 and IFN-gamma did not change after ivermectin treatment. Flow cytometric analysis of lymphocyte-subsets in the peripheral blood of untreated patients revealed a relative and absolute (P less than 0.01) diminution of CD4+ cells and a significantly smaller CD4+/CD8+ cell ratio as compared with controls. By 4 weeks after treatment and thereafter, CD4+ T cells increased relatively and absolutely (P less than 0.01); likewise there was an absolute increase in T-helper-inducer cells (CD4+CD45RO+) and a temporarily improved CD4+/CD8+ cell ratio (P = 0.001). The expression of the low-affinity receptor for IgE (CD23) on total lymphocytes decreased from 14% to 7% by 14 months after treatment. The CD8+ cells and CD3+TCR gamma delta + cells were higher in patients than in controls and both remained elevated until 14 months after treatment. These results suggest a distinctly improved cellular immunity in human onchocerciasis that was facilitated by ivermectin therapy.

The rare combination of intestinal lymphangiectasia with malrotation of the duodenum in a child of three months of life is described. Basing on the literature review only 3 similar cases were described in the world practice. The boy with protein-losing enteropathy was examined at Moscow Scientific Centre of Children's Health. The child had vomiting, diarrhea, loss in body weight, hypoproteinemia, lymphopenia. The infectious nature of the disease was excluded. It had been suggested the Waldman desease (primary intestinal lymphangiectasia). The prognosis for such disease is unfavorable. An examination of the child was continued against the backdrop of ongoing symptomatic therapy. Complete physical examination included monitoring laboratory blood tests, X-ray examination with contrast, CT-scan, gastroduodenoscopy with biopsy of the mucosa of the small intestine. Malrotation duodenum with the recurrent mid-gut volvulus with the development of secondary intestinal lymphangiectasia was diagnosed. Modern methods of examination and multidisciplinary approach made it possible to diagnose the case. Operation to eliminate fixation duodenum resulted in the recovery of the patient. At the present time the child grows and develops according to age and does not require treatment. The prognosis for this disease is regarded as favorable.
