ABSTRACT
OBJECTIVE: It was the aim of this study to report 3 rare fatal cases of strongyloidiasis in Kuwaiti renal transplant patients. CLINICAL PRESENTATION AND INTERVENTION: All 3 cases received allografts from cadaveric donors of Asian origin, the first 2 from an Indian (transplanted on the same day) and the third from a Bangladeshi. In all 3 cases, Strongyloides stercoralis larvae were first isolated from bronchoalveolar lavage. All 3 patients were on immunosuppressive therapy which included prednisolone, thereby leading to the hyperinfection syndrome. All patients presented with gastrointestinal symptoms (abdominal pain, vomiting, diarrhea, constipation and paralytic ileus), as well as pulmonary symptoms (cough, dyspnea and blood-stained sputum). Albendazole 800 mg twice daily orally was started. Cyclosporine A was started after discontinuing prograf. The patients continued to deteriorate with a fall in blood pressure and platelets. All 3 patients died from adult respiratory distress syndrome following hyperinfection with S. stercoralis. CONCLUSION: Hyperinfection with S. stercoralis is a rare but preventable complication of immunosuppressive therapy. A high index of suspicion is required for the diagnosis of this infection. Persistent examination of sputum, bronchial washings and upper intestinal aspirates should be done as part of surveillance following cadaveric renal transplantation. Adult respiratory distress syndrome is indeed a red flag in patients who are on steroids, not on cyclosporine and receiving a kidney from donors in endemic countries of S. stercoralis.

The numbers of T lymphocytes and T cell subsets (CD2(+), CD3(+), CD4(+), CD8(+)), activated T cells (CD26(+)), B cells (CD19(+)), granulocytes (CD15(+)) and natural killer cells (CD16/56) were monitored by flow cytometry in 79 kidney transplant recipients, 35 of whom had cytomegalovirus infection. The percentages of these cells were correlated with viral load, as determined by cytomegalovirus antigenemia. Development of cytomegaloviral infection coincided with a significant reduction in the percentages of CD4(+) (P < 0.005) and CD3(+) (P < 0.05) cells. Monitoring of lymphocyte subsets may provide useful information on immunological events during cytomegaloviral infection.

This study was aimed at determining (a) the extent of proliferation of peripheral blood mononuclear cells (PBMC) in response to stimulation by cytomegalovirus (CMV)-infected fibroblasts and (b) the levels of Th1 and Th2 cytokine production in kidney transplant recipients with and without active CMV infection. Thirty patients with, and 39 without active CMV infection, diagnosed by a CMV antigenemia assay (AA), were studied. PBMC of patients with active CMV infection showed significantly lower proliferation than those without ongoing CMV infection (P<0.0001). The levels of Th2-type cytokines (interleukin (IL-) 4 and IL-10) in AA-negative and AA-positive kidney transplant recipients were similar but the levels of the Th1-type cytokines interferon-gamma, tumor necrosis factor-alpha (P<0.05) and IL-2 were significantly lower in AA-positive kidney transplant recipients (P<0.0005).
