In this study we estimate influence of concomitant diseases and age on risk of death because of community-acquired pneumonia (CAP). We performed retrospective analysis of 405 CAP cases. All patients have been treated in Central Hospital of Military School of Medicine in Warsaw from 1990 to 1997. We showed statistically significant influence of age > 65 yr. (OR = 5.71; CI: 1.41-23.22; p = 0.015), chronic heart failure (OR = 2.57; CI: 1.1-5.99; p = 0.029) and chronic renal failure (OR = 3.35; CI: 1.06-10.54; p = 0.039) on high risk of death in patients with community-acquired pneumonia.

Neurotoxicity is an unusual complication of cephalosporin therapy. Only few cases of neurotoxicity induced by Cefepime have been described and probably the frequency of Cefepime-induced status epilepticus is underestimated. We report a case of an 82 year-old male, ESRD patient on chronic hemodialysis program affected by pneumonia, who received a treatment with intravenous Cefepime (1 g/day) and developed a seizure 4 days after the starting antibiotic therapy. Cefepime-induced neurotoxicity was suspected and its administration was immediately discontinued. In order to increase Cefepime clearance a hemodialysis session was urgently started and an improvement of his conscious level was observed. On the following day, after a second hemodialysis session his clinical condition and the status of neurotoxicity were completely recovered. The patient was discharged from the hospital in stable clinical condition one week later. At variance with the cases previously reported, the daily dose of Cefepime administrated to our patient was 50% lower and respected drug prescription dosage. Thus, we speculate on the hypothesis that advanced age of our patient and metabolic encephalopathy induced by chronic uremia made him more sensitive to the neurotoxicity induced by the drug. In conclusion, our case suggests that, in very old patients on long-term hemodialysis, it should be considered, to avoid neurotoxicity, to monitor the clinical neurological status, to use Cefepime at lower dosage than that allowed in patients with severe renal impairment (1 g/day) and, when possible, to evaluate Cefepime plasma levels. However, in these patients, other agents of the same class should be considered such as Cefotaxime and Ceftriaxone which are characterized by both an hepatic and renal excretion. In alternative to cephalosporins, antibiotics with the same action spectrum in the absence of neurological toxicity (i.e. Meropenem) should be recommended.

Agranulocytosis is a rare adverse effect associated with prolonged vancomycin therapy, and is potentially serious, especially in end stage renal disease (ESRD) patients. We describe a continuous ambulatory peritoneal dialysis (CAPD) patient that developed vancomycin-induced agranulocytosis during treatment for methicillin-resistant Staphylococcus aureus (MRSA)-associated external cuff infection and pneumonia. The agranulocytosis was rapidly resolved by granulocyte colony-stimulating factor (G-CSF) therapy and by the discontinuation of vancomycin.

This is the case of a 32-year-old male patient, diagnosed with end stage renal disease secondary to a focal and segmental glomerulonephritis. After four years of haemodialysis, he received a renal graft from a cadaveric donor. During the following sixteen years, he developped many different complications. In the early post-transplant period, he developed a severe acute tubular necrosis and two episodes of acute rejection took place, both of them with later recovery. Among the outstanding infectious complications were a virus herpes zoster dorsal infection and a Pseudomonas aeruginosa nosocomial pneumonia. Twelve months later, a series of severe digestive complications took place: cholecystitis that required cholecystectomy, pancreatic pseudocyst which required laparotomy because of an abdominal complication, two separate episodes of upper digestive bleeding that finally required gastric surgery, and an hemorrhagic subphrenic abscess that required a second laparotomy. Currently he has developed a calcified chronic pancreatitis. Moreover, metabolic complications must be mentioned carbohydrate intolerance, cataracts and an avascular bone necrosis, all of them closely related to the immunosuppressive therapy. In spite of these multiple complications, he mantains a good renal function and his quality of life is acceptable.

Eosinophilic peritonitis is defined as when there are more than 100 eosinophils present per milliliter of peritoneal effluent, of which eosinophils constitute more than 10% of its total WBC count. Most cases occur within the first 4 weeks of peritoneal catheter insertion and they usually have a benign and self-limited course. We report a patient of eosinophilic peritonitis that was successfully resolved without special treatment. An 84-year-old man with end stage renal disease secondary to diabetic nephropathy was admitted for dyspnea and poor oral intake. Allergic history was negative. and physical examination was unremarkable. Complete blood count showed a hemoglobin level of 11.1 g/dL, WBC count was 24,500/mm3 (neutrophil, 93%; lymphocyte, 5%; monocyte, 2%), platelet count was 216,000/mm3, serum BUN was 143 mg/dL, Cr was 5.7 mg/dL and albumin was 3.5 g/dL. Creatinine clearance was 5.4 mL/min. Three weeks after peritoneal catheter insertion, he was started on peritoneal dialysis with a 6-hour exchange of 2L 1.5% peritoneal dialysate. After nine days, he developed turbid peritoneal effluents with fever (38.4 degrees C), abdominal pain and tenderness. Dialysate WBC count was 180/mm3 (neutrophil, 20%; lymphocyte, 4%; eosinophil, 76% [eosinophil count: 136/mm3]). Cultures of peritoneal fluid showed no growth of aerobic or anaerobic bacteria, or of fungus. Continuous ambulatory peritoneal dialysis (CAPD) was commenced, and he was started on intraperitoneal ceftazidime (1.0 g/day) and cefazolin (1.0 g/day). After two weeksr, the dialysate had cleared up and clinical symptoms were improved. Dialysate WBC count decreased to 8/mm3 and eosinophils were not detected in peritoneal fluid. There was no recurrence of eosinophilic peritonitis on follow-up evaluation, but he died of sepsis and pneumonia fifteen weeks after admission.

In Thailand, the death rate from community-acquired pneumonia (CAP), especially severe CAP, has increased steadily over the past decade. To optimize the outcome, rapid start of appropriate antibiotics and supportive care are the mainstay of management. We therefore assessed the local etiology and outcome of adult patients with severe CAP admitted between January 1, 1999 and December 31, 2001. One hundred and five of 383 patients (27.4%) met the ATS criteria for severe CAP. The mean age was 56.9 (SD 18.2) years. The male to female ratio was 60:45. Duration of symptoms before admission was 5.3 (SD 4.0) days. Most of them (91.4%) had co-morbidity, diabetes mellitus being most common. A microbiological pathogen was isolated in 62 patients (59%). The pathogens most commonly isolated were B. pseudomallei (29.4%), S. pneumoniae (20.6%), K. pneumoniae (19.1%), and H. influenzae (11.8%). Other less common pathogens were E. coli (5.9%), S. aureus (5.9%), M. pneumoniae (1.5%), M. catarrhalis (1.5%), P. aeruginosa (1.5%), P. fluorescens (1.5%), and S. stercoralis (1.5%). Hospitalization averaged 14.7 (SD 14.3) days and mortality was 21%. Clinicals in 17.1 % of patients did not improve and they transferred home. Most (81.9%) patients required mechanical ventilation, while 60 (57.1%) developed septic shock, and 13 (12.3%) acute renal failure. Severe CAP carried high mortality, despite intensive care. Empirical therapy for B. pseudomallei should be considered, where endemic, and for patients with diabetes mellitus or chronic renal failure.

Though the pathogenic significance and the reservoir of Ewingella americana have not been clarified, this organism has caused several pathogenic infections, especially in immunocompromised patients. We report a pneumonia in a patient with chronic renal failure, who had chronic rejection of transplanted kidney. E. americana was identified to be the pathogen of pneumonia with clinical symptoms and signs and radiological examination. As soon as he was treated with ceftriaxone and isepamicin, clinical improvement was followed with no further growth of E. americana or other pathogenic isolates from sputum culture. This suggests to be the case of pneumonia caused by E. americana for the first time in the Korean literature.

In this retrospective study we present our experience with chronic peritoneal dialysis in nine patients with ESRD in their 10th decade of life (> or =90 years) at the Toronto Western Hospital. A family member or a private nurse assisted all patients in dialysis procedure. The co-morbid illnesses, survival, hospitalizations and complications related or unrelated to peritoneal dialysis were reviewed. Four patients started dialysis before and five after their 90th birthday, their mean age was 90.61+/-4.04 years. All patients had three or more co-morbid illnesses at the start of dialysis. Total duration of PD treatment was 210 patient months with a median duration of 25 months (range 4-68 months). Of the nine patients, four died after a mean follow up of 38.5 months on dialysis. Of the remaining five, one was transferred to hemodialysis after remaining for 10 months on peritoneal dialysis and the other four are continuing on PD for a mean duration of 9.25 months. Peritonitis (1/13.4 patient months) and exit site infection (1/100.5 patient months) responded to treatment. Hospitalization rate was one admission per 2.5 patient years. Most often, the cause of hospitalization was unrelated to PD, e.g., cardiovascular events, pneumonia and peripheral vascular disease etc. Patient survival at 1, 3 and 5 years was 88%, 58% and 24% respectively. The technique survival was 69%, 47% and 23% at 1, 3 and 5 years respectively. We conclude that continuous peritoneal dialysis is a safe and suitable treatment even in nonagenarians (> or =90 years) ESRD patients.

In this retrospective single-centre study, 96 consecutive myeloma patients were treated with melphalan 200 mg/m(2) with blood stem cell support as first-line therapy. Their mean age was 55 (38-65) years. The impact of renal function on stem cell collection yield, engraftment, transplantation-related toxicity and overall survival was studied. Glomerular filtration rate (GFR) was evaluated by iohexol clearance, a median 32 days before high-dose administration. Chronic renal failure (GFR <60 ml/min) was present in 19 patients, with severe failure (GFR <30 ml/min) in five patients, including one patient on haemodialysis. No relationship between GFR and stem cell collection yield or engraftment was observed, nor was the incidence of neutropenic fever or infectious complications related to GFR. Patients with subnormal renal function, however, were more often affected by severe mucositis. In addition, the two patients with severe GI bleeding, the two pneumonia patients who needed ventilator support and the only therapy-related death were noted in the five patients with severe renal failure. Lower iohexol clearance at the time of high-dose administration was found to have a poor impact on survival. A reduction of melphalan dose in patients with severe renal failure, here defined as iohexol clearance <30 ml/min, is suggested.

A retrospective study of Streptococcus pneumoniae bacteraemia among adult patients in two large teaching hospitals in Spain identified 108 (10.6%) of 1,020 episodes as nosocomial pneumococcal bloodstream infections (NPBIs). Seventy-seven clinical records with sufficient data were available for analysis. The interval between admission and a positive blood culture was 3--135 days (median 17 days; interquartile range 8--27). The main underlying and predisposing conditions for NPBI were malignancy (31%), chronic obstructive pulmonary disease (28.6%), heart failure (16.9%), chronic renal failure (15.6%), liver cirrhosis (13%) and infection with human immunodeficiency virus (13%). Overall, 31.2% of patients developed severe sepsis, 11.7% septic shock, and 3.9% multi-organ failure. The main portals of entry were pneumonia (70.1%), meningitis (5.2%) and primary peritonitis (5.2%). Of the responsible serogroups, 78% were included in the 23-valent polysaccharide vaccine. Thirty-five (45.5%) patients died, with death considered to be related to the NPBI in 21 (27.3%) cases. Following multivariate analysis, factors that independently predicted death after adjusting for age were: ultimately fatal underlying disease (OR, 8.9; 95% CI, 0.8--94.3; p<0.001); rapidly fatal underlying disease (OR, 15.0; 95% CI, 2.8--81.3; p<0.001); heart failure (OR, 8.11; 95% CI, 1.1--60.8; p<0.03); inadequate empirical therapy (OR, 10.6; 95% CI, 1.2--97; p<0.003); a severe sepsis score (OR, 9.5; 95% CI, 1.9--47.0; p<0.001); and septic shock or multi-organ failure (OR, 63.7; 95% CI, 4.9--820.7; p<0.001). Adequate empirical therapy was an independent protective factor (OR, 0.05; 95% CI, 0.04--0.58; p<0.005), but the use of more than one antimicrobial agent was not.
