RESUMO
Two patients were contaminated by hepatitis during kidney transplantation from unrelated living donors, performed abroad in 2006. One patient died from fulminant hepatitis C (the first case of virus genotype 6a diagnosed in Israel) 2 months after transplantation and the other developed acute hepatitis B with YMDD to YVDD mutation necessitating life-long antiviral therapy. The dilemma of antiviral therapy in transplant recipients is discussed in this paper. Patients awaiting kidney transplantation by far outnumber the kidneys available for cadaver transplantation. International trade with living non-related kidneys has therefore become common. Comorbid conditions, although significant, are often ignored. After transplantation, the first patient presented with a picture of fulminant hepatitis C; immunosuppressive medication was tapered rapidly. This patient subsequently died from hepatic failure. The patient with active hepatitis B with YVDD mutation is receiving ongoing treatment by lamivudine and adefovir.

Autosomal dominant familial nephropathies with adult onset, no macroscopic cysts, and progressive deterioration include medullary cystic disease (ADMCKD) as well as other less specific entities. We studied a kindred of Jewish ancestry in which 15 members (both male and female) have suffered from chronic renal failure. The first evidence of renal involvement was observed between 18 and 38 years. It included hypertension followed by progressive renal insufficiency. No polyuria, anemia, gout, hematuria, nor proteinuria were seen. An average of 4.5 years elapsed from diagnosis to end-stage renal disease. Renal pathology at early stages of the disease showed extensive tubulointerstitial fibrosis and global glomerulosclerosis. Linkage analysis was performed at the two known loci of ADMCKD, on Chromosomes 1 and 16. Linkage to the chromosome 16 locus was excluded. However, linkage to the chromosome 1q21 locus of ADMCKD was established with a maximum two-point LOD score of 3.82 to D1S394. The disease interval could be narrowed to about 9 cM/7.4 Mb between D1S1156 and D1S2635. Multiple-point linkage analysis revealed a maximum LOD of 4.21, with a broad peak from markers D1S2858 and D1S2624. This report establishes linkage between a familial nephropathy characterized by hypertension and progressive renal failure to the locus described for ADMCKD, a disease classically associated with macroscopic corticomedullary cysts, salt-losing tubulointerstitial nephropathy, and anemia. This finding broadens the clinical spectrum of ADMCKD positioned on chromosome 1q21 locus.

BACKGROUND/AIM: Few cases are found in the literature regarding autoimmune hemolytic anemia which is Coombs' test positive in kidney transplant patients, although hemolytic uremic syndrome due to cyclosporin and FK506 has been well described. In the following, we describe a case of severe life-threatening Coombs' test negative autoimmune hemolytic anemia after kidney transplantation. METHODS: Soon after undergoing renal transplantation, the patient presented with hemolytic anemia. Kidney biopsy, routine Coombs' test, gel filtration and flow-cytometric assay were undertaken. RESULTS: Kidney biopsy ruled out hemolytic uremic syndrome; although Coombs' test and gel filtration assay were negative, flow cytometry revealed circulating antierythrocytic autoantibodies. CONCLUSIONS: Our findings indicate that flow cytometry may be an efficient method in the diagnosis of hemolysis of unknown origin in transplant patients. We further hypothesize that the underlying mechanism of autoimmune hemolytic anemia is related to the passenger B lymphocytes in the graft.

We report a case of progressive deterioration in renal function and decreased renal graft perfusion induced by extensive aorto-iliac atherosclerotic lesions proximal to a patent renal graft artery. Significant improvement in kidney graft function followed left axillo-femoral bypass graft surgery, which to the best of our knowledge, has never been performed previously for permanent maintenance of renal transplant perfusion.

OBJECTIVES: Recent interest has been expressed in rheumatic manifestations in hepatitis C virus (HCV)-infected populations. The aim of this study was to determine the prevalence and characteristics of the musculoskeletal manifestations and serological markers of autoimmunity in HCV-infected patients in Israel. METHODS: Ninety anti-HCV-positive patients were consecutively interviewed and examined. The prevalence of autoantibodies and their association with rheumatologic symptoms were also determined. RESULTS: Rheumatic manifestations were found in 28 subjects (31%), and included arthralgias (9%), arthritis (4%), cryoglobulinemia (11%), sicca symptoms (8%), cutaneous vasculitis (2%), polymyositis (1%), and antiphospholipid syndrome (1%). Rheumatic complications were not associated with liver disease severity, or subjects' gender. In addition, myalgia was reported by 22 patients (24%), and fibromyalgia was diagnosed in 14 (16%). Sixty-nine percent of the patients had at least one autoantibody detected in their serum, the most prevalent being rheumatoid factor (RF), 44%; antinuclear antibody (ANA), 38%; and IgM and IgG anticardiolipin antibodies (ac1), 28% and 22%, respectively. The frequency of autoantibodies was not associated with liver disease severity or rheumatic disorders. CONCLUSIONS: Musculoskeletal manifestations and autoimmune markers are common in HCV infection. An investigation of risk factors for HCV infection is pertinent in a patient presenting new rheumatic manifestations and should be included in the history of present illness. Future studies of these disorders may uncover the full spectrum of these associations and provide new insights into their operating mechanisms.

Enterococcus hirae, member of the Enterococcus genus known to cause infection in animals, is rarely encountered in clinical practice. There are no published reports describing clinical features of Enterococcus hirae infection in humans. A case of Enterococcus hirae septicemia in a 49-year-old patient with end-stage renal disease undergoing hemodialysis is reported here. A review of the available literature regarding the clinical spectrum of Enterococcus hirae infection in humans and the antimicrobial susceptibility of Enterococcus hirae is also included.

BACKGROUND: Fibromyalgia syndrome (FS) is a common disorder of diffuse pain in the muscles or joints accompanied by tenderness at specific tender points and a constellation of related symptoms. The potential role of infections in the pathogenesis of FS has only recently been investigated. OBJECTIVES: To evaluate the prevalence of FS and to assess tenderness thresholds in patients infected with hepatitis C virus (HCV). METHODS: The study included 90 patients with HCV, 128 healthy, anti-HCV-negative controls, and 32 patients with non-HCV-related cirrhosis. Tenderness was measured by manual palpation (18 tender points) and with a dolorimeter. Fibromyalgia syndrome was diagnosed according to the 1990 American College of Rheumatology criteria. RESULTS: The diagnosis of FS was established in 14 patients (16%) with HCV, in 1 patient (3%) with non-HCV-related cirrhosis, and in none of the healthy controls (P < .001). Thirteen of the HCV-positive patients with FS were women. The patients with HCV had significantly (P < .01) more tender points (mean [+/- SD] 3.6 +/- 5.3) than the healthy controls (0.1 +/- 0.5) and the patients with non-HCV-related cirrhosis (1.2 +/- 2.7). Specifically, the patients with cirrhosis were most tender on both tenderness measures owing to the high proportion of women in this group. Patients with FS were significantly more tender than those without FS: their dolorimetry thresholds were 2.9 kg vs 6.0 kg (P < .001). CONCLUSIONS: A high prevalence of FS was observed in patients infected with HCV, especially women. Recognizing FS in patients with HCV will prevent misinterpretation of FS symptoms as part of the liver disease and will enable the physician to reassure the patient about these symptoms and to alleviate them.

An association between chronic hepatitis C (HCV) infection and non-Hodgkin's lymphoma has been reported. We carried out this study to evaluate the possibility of an association between HCV infection and other extrahepatic malignancies. The medical records of 103 unselected, consecutively chosen, anti HCV-positive and 105 hepatitis B surface antigen (HBsAg)-positive patients attending the liver clinic or hospitalized in the Department of Medicine were reviewed. Patients in whom anti-HCV positivity was detected after the malignancy was diagnosed were excluded. Malignancy rates in the general Israeli population were obtained from the Israeli cancer registry. The ages of anti-HCV-positive and HBsAg-positive patients were 54 +/- 16 (+/-SD) (range, 15-84) and 45 +/- 12 (range, 20-78) years, respectively; the male/female ratios were 50/53 and 73/32, respectively. Extrahepatic malignancies were found in 15 (14.6%) of the anti-HCV and in three (2.9%) of the HBsAg-positive patients. Thirteen of the malignancies were found among the 60 anti-HCV-positive patients aged > or =55 years old. Only one malignancy was found among the 28 HBsAg-positive patients of the same age group (p < 0.01). The rate of extrahepatic malignancies in these HCV-infected patients was significantly higher (p < 0.01) than expected in the general population. An association between HCV infection and extrahepatic malignancy may exist, but further prospective studies, including a large number of patients with HCV infection, will be necessary to define this observation.

The main causes of the development of chronic abscesses of the lungs in 41 patient were the presence of the pulmonary tissue sequesters, interlobar location of a process, large (5 cm and more) diameter of the cavities. The infiltrative form of an abscess was distinguished. The process should be considered as chronic in ineffectiveness of all the types of treatment. With the use of the conservative methods, 14 patients were cured.
