Goodpasture's disease in association with human immunodeficiency virus (HIV) is rarely observed. Herein, we report a case of a 33-year-old Hispanic male who had both HIV and hepatitis C, and was subsequently diagnosed with autoantibodies to the glomerular basement membrane. On initial presentation he was anuric and hyperkalemic with an elevated creatinine. Hemodialysis was initiated, and a renal biopsy showed findings diagnostic of anti-glomerular basement membrane crescentic glomerulonephritis. Immunofluorescence microscopy showed strong (3+) linear staining of glomerular basement membranes by IgG, kappa; and lambda; light chains, and focal weaker staining of glomerular basement membranes for C3. Plasmapheresis, steroids and cyclophosphamide were all considered in treating this complex case. The patient received therapy with plasmapheresis and steroids during his initial hospitalization, but his renal function did not improve. He was discharged on hemodialysis 3 times per week. On a subsequent admission, the patient presented with symptoms and signs suggestive of pulmonary hemorrhage. Thus, plasmapheresis and cyclophosphamide were begun. His pulmonary symptoms improved with therapy, but he continued to require long-term hemodialysis. The development of Goodpasture's syndrome in a patient with HIV infection creates diagnostic and therapeutic dilemmas. The decision to treat the patient with immunosuppressive medications should lead to enhanced surveillance for infections.
与人类免疫缺陷病毒(HIV)相关的肺出血肾炎综合征很少见。在此,我们报告一例33岁的西班牙裔男性病例,该患者同时感染了HIV和丙型肝炎,随后被诊断出存在抗肾小球基底膜自身抗体。初次就诊时,他无尿、高钾血症且肌酐升高。开始进行血液透析,肾活检结果诊断为抗肾小球基底膜新月体性肾小球肾炎。免疫荧光显微镜检查显示,肾小球基底膜有强烈的(3+)IgG、κ和λ轻链线性染色,C3在肾小球基底膜有局灶性较弱染色。对于这个复杂病例,血浆置换、类固醇和环磷酰胺都在治疗方案的考虑范围内。患者在初次住院期间接受了血浆置换和类固醇治疗,但肾功能没有改善。他出院后每周进行3次血液透析。在随后的一次住院中,患者出现了提示肺出血的症状和体征。因此,开始进行血浆置换和环磷酰胺治疗。治疗后他的肺部症状有所改善,但仍需要长期血液透析。HIV感染患者发生肺出血肾炎综合征会带来诊断和治疗上的难题。决定用免疫抑制药物治疗患者应加强对感染的监测。
