An 88-year-old man with a 30-year history of type 2 diabetes and a 3-year history of chronic renal failure was admitted for evaluation of anasarca. On admission, findings of nephrotic syndrome and microscopic hematuria were observed. During the course of therapy, rapid deterioration of renal function occurred with the appearance of pneumonia. Irrespective of the therapy with hemodialysis and antibiotics, he died of respiratory failure. The autopsy showed a rare case of rapidly progressive glomerulonephritis (crescentic glomerulonephritis) superimposed on membranous nephropathy. This experience highlighted the importance of the differential diagnosis of non-diabetic glomerulopathy even in elderly patients with diabetes mellitus.

Patients with rapidly progressive glomerulonephritis who are positive for anti-neutrophil cytoplasmic antibody (ANCA) or anti-glomerular basement membrane (GBM) antibodies may develop chronic renal failure leading to end-stage renal disease (ESRD) within days or weeks. The early serologic detection of auto-antibodies associated with ANCA and anti-GBM diseases will be helpful in preventing ESRD. We evaluated the combined ANCA-GBM dot-blot strip assay (Biomedical Diagnostics, Brugge, Belgium) in 30 consecutive patients with biopsy proven glomerulonephritis (GN). MPO- and PR3-ANCA were detected in 5 and 2 samples, respectively. Three samples were positive for both MPO- and PR3-ANCA (all 3 had focal segmental necrotizing GN). One patient was diagnosed as having Goodpastures' syndrome (the only anti-GBM positive result) and two had Wegener's granulomatosis (the two PR3-ANCA positive results). Two additional samples were equivocal: positive for MPO-ANCA and PR3-ANCA, respectively. Patients positive only for MPO-ANCA had only limited extrarenal organ manifestations. Anti-PR3 positive patients with necrotizing glomerulonephritis had a more dramatic deterioration of their renal function at diagnosis. Radiographically, these patients had nodular or pneumonia-like lesions. Acute respiratory failure necessitating mechanical ventilation was developed in one GBM positive patient. In conclusion, the ANCA-GBM dot-blot is a useful screening tool in situations where conventional ANCA testing is not readily available.

Legionella species have been widely recognized as among the important causative organisms of community-acquired pneumonia in Japan. A delay in the start of adequate treatment has a negative influence on the outcome of the disease. Telithromycin, the first oral ketolide antibacterial, was developed for the treatment of community-acquired pneumonia, including Legionella pneumonia. However, few reports have indicated the efficacy of telithromycin in community-acquired pneumonia caused by Legionella species. We report three cases of Legionella pneumonia, that were improved by early telithromycin therapy. The first patient (67-year-old man) had bronchiectasis as an underlying disease, and the second patient (73-year-old man) had diabetes mellitus and chronic renal failure. The third patient (62-year-old man) developed pneumonia after a spa tour. The diagnosis of Legionella pneumonia was made on the basis of the presence of a single IgG titer of 1/256 in case 1 and positive antigenuria in cases 2 and 3. The patients were classified into a mild group (case 1) and a moderate group (cases 2 and 3) based on the severity of the community-acquired pneumonia according to the 2005 Japanese Respiratory Society Guidelines. The results support the efficacy of telithromycin in mild to moderate Legionella pneumonia.

As a consequence of the expanded use of long-term hemodialysis and extended life spans, complications of chronic renal failure are encountered with an increased frequency among uremic patients. Such patients may develop many thoracic and extrathoracic problems--most frequently uremic pleuritis and pericarditis, uremic pneumonia, infection, and metastatic pulmonary calcification. We retrospectively analyzed the medical records of 257 patients who had received long-term hemodialysis between 1990 and 2006 to better understand the incidence, causes, and clinical features of pleural effusions in this population. The incidence of pleural effusion in hospitalized patients receiving long-term hemodialysis was 20.2% (n=52; mean age, 55.83 +/- 16.56 years; male-to-female ratio, approximately 3:2). Pleural effusion resulted from hypervolemia in 61.5% and was bilateral in 68.8% of patients. Unilateral effusion was present in 25 of 52 (48%) patients. The most frequent causes of unilateral effusion were hypervolemia (n=9) and parapneumonic effusion (n=5). Thoracenteses were performed in 14 of the 52 patients in the study group. Of thoracenteses performed, 64.3% of the patients had transudative pleural effusion and 35.7% had exudative effusion. Transudative pleural effusion resulted from hypervolemia in 66.7% and heart failure in 22.2%. Of the patients with transudative effusion, 85.7% were bilateral. The most frequent cause of exudative pleural effusion was uremic pleuritis, which occurred in 40% of the patients. The most common symptom was dyspnea, which occurred in 53.8% of patients. In conclusion, pleural effusions are common in patients receiving chronic hemodialysis. Thoracentesis may be performed in patients with unilateral pleural effusion. Since hypervolemia was the most common cause of pleural effusion, this complication should not be considered an obstacle in renal transplant recipients.

This study aimed to develop a new risk-adjustment method to assess acute myocardial infarction (AMI) in-hospital mortality. Risk-adjustment was based on variables obtained from administrative data from Japanese hospitals, and included factors such as age, gender, primary diagnosis and co-morbidity. The infarct location was determined using the criteria of the International Classification of Diseases (10th version). Potential comorbidity risk factors for mortality were selected based on previous studies and their critical influence analysed to identify major co-morbidities. The remaining minor co-morbidities were then divided into two groups based on their medical implications. The major co-morbidities included shock, pneumonia, cancer and chronic renal failure. The two minor co-morbidity groups also demonstrated a substantial impact on mortality. The model was then used to assess clinical performance in the participating hospitals. Our model reliably employed the available data for the risk-adjustment of AMI mortality and provides a new approach to evaluating clinical performance.

A 72-year-old critically ill and intubated man was transferred to our hospital, because of worsening pneumonia unresponsive to Cefazolin and Meropenem, from the hospital where he had been admitted 8 days before to start maintenance hemodialysis for chronic renal failure but had fever from admission. In a few days his critical condition rapidly subsided with the initiation of Ciprofloxacin and his sputum culture on GVPC medium indicated Legionellosis, which was afterwards identified as L. longbeachae by PCR and DNA-DNA hybridization. After recovery he said that he had been fond of gardening and had been gardening immediately before the initial admission. Moreover, several reports from Australia suggested inhalation of aerosolized potting soil as the route of L. longbeacachae infection; therefore, we examined the soil of his home garden and identified it. Thus, we present this case as the first of L. longbeachae pneumonia in Japan, proved to be infected via inhalation of aerosolized home garden soil.

The subjects of the study were 176 patients with chronic renal failure (CRF) (101 men; 75 women) aged 17 to 81. Stage I CRF was found in 46 patients, stage II CRF--in 69 patients, and stage III CRF--in 61 patients. Thirty-one patients with stage III CRF received program hemodialysis. Chronic glomerulonephritis was the main cause of CRF. With the progress of CRF, the frequency of infectious complications grew up to 2.2% in stage I, 7.2% in stage II, and 36.1% in stage III. The rate of infectious complications was higher in patients on program dialysis vs. patients without it: 51.6 and 20%, respectively. Pneumonia was the most frequent complication regardless CRF stage.

A 76-year-old woman hemodialysis patient was hospitalized for community-acquired pneumonia complicating chronic obstructive pulmonary disease. End-stage renal disease secondary to hypertension had been diagnosed at the age of 64 for which the patient was initiated on maintenance hemodialysis. Then, she received a deceased donor kidney transplant at the age of 68 that succumbed to chronic rejection 4 years later when she was restarted on hemodialysis. Hemodialysis was performed via a right subclavian vein double lumen catheter for 2 months when a right brachio-axillary graft was inserted. Severe venous congestion, swelling, and nipple tenderness of her right breast noted on admission had been increasing for 6 weeks before hospital admission. No arm swelling was evident. Initial management of the patient's pneumonia and chronic obstructive pulmonary disease consisted of intravenous ceftriaxone and albuterol inhaler to which intravenous oxacillin (1 g q 6 hr) was added for presumed right mastitis. Radiological work-up for masses and malignancies was negative. An angiogram of the right upper extremity detected stenosis of the dialysis access graft at its anastomosis with the axillary vein. Angioplasty of the stenosis was performed without incident or evidence of central vein stenosis. Rapid resolution over 10 days of the unilateral breast congestion followed without complication.

The current are evidence of success in renal transplantation in this center, and this is consistent with data from the UNOS study. However, the current study also suggests that transplantation in China is quite different from that in Europe and America. The undergoing diseases in China are mainly primary glomerular diseases; IgA nephropathy accounts for a quarter of ESRD, while diabetes nephropathy accounts for only 3.13% of ESRD. Only small doses of MMF and Tac can inhibit rejection and result in a decreased incidence of infection. The leading causes of death after renal transplantation are severe pneumonia and liver failure. With the exception of late rejection, death with a functional graft is another significant cause of graft loss.

Although Legionnaires' disease occurs more commonly in patients with some degree of immunosuppression (diabetes, chronic lung disease, end stage renal disease, cancer, etc.), it has been infrequently described in patients infected with human immunodeficiency virus (HIV) and AIDS. Some studies suggest that pneumonia caused by Legionella tends to present with more severe clinical features and complications in the HIV-infected population. The use of antibiotic prophylaxis or the association of severe pneumonia with other pathogens may account for under diagnosis of the disease. We diagnosed five cases of Legionella pneumonia in patients with HIV infection at our institution during a 1-year period. The cases seen ranged in severity, regardless of the CD4(+) counts of the patients. Based on our observations, it seems impossible to discern whether HIV infection is an additional risk factor for Legionnaires' disease. We describe those five cases and review the available literature.
