目的探讨TNF-α和TGF-β1在慢性非细菌性前列腺炎患者前列腺液中的表达及临床意义。方法采用双抗体夹心法对20例炎症型慢性非细菌性前列腺炎即炎症型慢性骨盆疼痛综合征(Ⅲa型),20例非炎症型慢性非细菌性前列腺炎即非炎症型慢性骨盆疼痛综合征(Ⅲb型),10例健康对照者前列腺液(EPS)中TNF-α、TGF-β1含量进行测定。采用美国国立卫生院慢性前列腺炎症状评分(NIH-CPSI)进行相关性研究。结果①TNF-α在Ⅲa型患者EPS中表达水平[(152.44±83.06)pg/ml]明显高于Ⅲb型组[(93.15±57.26)pg/ml]和健康对照组[(78.99±53.51)pg/ml],P<0.05。但在Ⅲb型和健康对照组之间差异无统计学意义,P>0.05。②TGF-β1在Ⅲa型组[(8477.50±4612.45)pg/ml]和Ⅲb型组[(7946.50±5044.06)pg/ml]表达水平均明显高于健康对照组[(2462.50±985.31)pg/ml],P<0.01。但在Ⅲa和Ⅲb型之间差异无统计学意义,P>0.05。③前列腺液中TNF-α、TGF-β1的水平与慢性前列腺炎症状评分无相关性(r=0.23,P>0.05;r=0.31,P>0.05)。结论前列腺液中细胞因子(TNF-α、TGF-β1)在慢性前列腺炎的病理学改变中起重要作用,可作为慢性前列腺炎的诊断依据之一。

Nephrotic syndrome associated with hemophagocytic syndrome

Hemophagocytic syndrome (HPS) is defined by bone marrow and organ infiltration by activated, nonmalignant macrophages, which phagocytose blood cells. The clinical spectrum of HPS is broad, but renal involvement has rarely been investigated. We report a previously unknown renal manifestation of HPS: nephrotic syndrome. This multicentric retrospective study included patients fulfilling the following criteria: (i) no history of nephropathy; (ii) HPS diagnosis with histologic evidence of hemophagocytosis; (iii) occurrence of nephrotic syndrome during HPS; and (iv) available renal histology. Using the same criteria, we also searched the literature for additional cases. We identified nine patients retrospectively and found two additional cases in the literature (five males and six females, whose mean age was 34 +/- 27 years). Black African patients predominated (63.6%). HPS was due to lymphoma (six cases), infectious disease (three cases), and autoimmune disease (one case), and was primary in one patient. Acute renal failure was associated with nephrotic syndrome in 10/11 cases. Renal histology showed acute tubular necrosis associated with collapsing glomerulopathy in five patients (all Africans with negative human immunodeficiency virus serology), minimal change glomerulopathy in four, and thrombotic-microangiopathy with abnormal podocytes in two. Death occurred in seven cases. Nephrotic syndrome should be included among the renal complications of HPS with acute renal failure. We postulate that abnormal T-cell activation and/or high pro-inflammatory cytokine levels during HPS might cause podocyte injuries, especially among African patients with a susceptible genetic background.     

Hemolytic uremic syndrome associated with Denys-Drash syndrome

The Denys-Drash syndrome is defined by the occurrence of combinations of pseudohermaphroditism, nephrotic syndrome with diffuse mesangial sclerosis, Wilms’ tumor, and constitutional mutations in the WT1 suppressor gene. Most patients develop end-stage renal failure. Atypical hemolytic uremic syndrome (HUS) is defined by onset of acute hemolytic anemia with fragmented erythrocytes, thrombocytopenia, and renal failure in the absence of a gastrointestinal prodromal illness of bloody diarrhea. The purpose of this report is to describe the occurrence of features of atypical HUS and Denys-Drash syndrome in two African-American boys aged 13 and 16 months. Each had nephrotic syndrome, diffuse mesangial sclerosis, and WT1 point mutations. Both had grade III hypospadias and undescended testes. They had normal serum creatinine concentrations and hematology a month before presenting with HUS. Stool cultures for Escherichia coli 0157:H7 were negative. Each patient has been transplanted with cadaver kidneys without recurrence of HUS. Received: 20 July 1999 / Revised: 22 February 2000 / Accepted: 17 March 2000     

Combined Alport syndrome,Klinefelter syndrome and Fanconi syndrome in a Chinese boy

Alport syndrome (AS) is a progressive renal disease characterized by hematuria and progressive renal failure. X-linked dominant (XLAS) is the major inheritance form, accounting for almost 80% of the cases, caused by mutations in COL4A5 genes. Klinefelter syndrome (KS) is the most common genetic cause of human male gonadal dysgenesis. AS and KS are both rare disease, there are only three cases of combined AS and KS in the literatures. Fanconi syndrome (FS) caused by AS is also very rare. We report here the first case combined AS, KS and FS in a Chinese boy. We suggest that the severe renal phenotype and FS might be due to the two homozygous COL4A5 variants in our boy, and cases of AS combined KS will be good research objects for X chromosome inactivation.
