Antithymocyte globulin-induced acute respiratory distress syndrome after renal transplantation: a case report / 中华医学杂志(英文版)

Antithymocyte globulin (ATG) has long been used for immune-induction and anti-rejection treatments for solid organ transplantations. To date, few cases of ATG-induced acute respiratory distress syndrome (ARDS) have been published. Here, we present a case of ARDS caused by a single low-dose of ATG in a renal transplant recipient and the subsequent treatments administered. Although the patient suffered from ARDS and delayed graft function, he was successfully treated. We emphasize that the presence of such complications should be considered when unexplained respiratory distress occurs. Early use of corticosteroids, adjustment of immunosuppressive regimens, and conservative fluid management, as well as empiric antimicrobial therapies, may be effective strategies for the treatment of ARDS caused by ATG.

The clinical characteristic of adrenal metastatic tumor / 中华外科杂志

<p><b>OBJECTIVE</b>To analyze the clinical features of adrenal metastasis.</p><p><b>METHODS</b>From January 1993 to December 2004, 103 cases of adrenal metastasis were reviewed.</p><p><b>RESULTS</b>Lung and hepatocellular carcinoma were the most common primary tumor of adrenal metastatic tumor, which about 36.9% (38/103) and 42.7% (44/103) of all cases, followed by renal carcinoma 6.8% (7/103), colorectal carcinoma 4.9% (5/103), stomach carcinoma 3.9% (4/103), breast cancer 1.9% (2/103), unknown primary tumor 2.9% (3/103). Most of these were low differentiation. The mean diameter of adrenal metastasis was 3.9 cm. The mean interval from detection of primary tumor to adrenal metastasis was 9.5 months. And 79.6% (82/103) were detected as a part of multiorgan metastasis. Only 5 cases (4.9%) were presented with pain in the back. There was little characterization of ultrasonography, CT and MRI, color-Doppler and selective arterial imaging showed little blood supply. All of patients were treated with synthetic methods, 16 cases (15.5%) who had undergone adrenalectomy for metastasis disease had a improved survival compared with those non-adrenalectomy.</p><p><b>CONCLUSIONS</b>There is no particular presentation of clinic and imaging, diagnosis depending on history, follow-up and the pathological presentation of primary tumor. There are no standard treatment guidelines for this group of patients. When the primary tumor could be resected or be well controlled, and there is no other evidence of metastasis, adrenalectomy is recommended. Transarterial chemoembolization (TACE) could not actually be performed.</p>
