Sputum gram stain assessment in community-acquired bacteremic pneumonia.

A prospective study was performed over a 4.5-year period to determine the ability of a sputum Gram stain to predict the cause of community-acquired bacterial pneumonia. A blood culture isolate, rather than a sputum culture, served as the reference standard to provide precise identification of the etiologic agent. The study population comprised 59 bacteremic adults who expectorated a valid sputum sample. Data are presented that indicate that a physician, aided by the morphology of the stained sputum, could theoretically select appropriate monotherapy approximately 94% of the time when selective, defined criteria for the microbiology of valid sputum are met. Three of the five patients with pneumonia caused by Haemophilus influenzae, however, had sputum stains that suggested alternative pathogens. This study reaffirms that the Gram-stained sputum is a reliable, but not infallible, guide to direct initial antibiotic therapy in adults with community-acquired bacterial pneumonia.

Therapy of symptomatic pyelonephritis in women.

A prospective randomized controlled study was performed on 44 women with community-acquired, uncomplicated pyelonephritis requiring hospitalization. The study was designed to determine if an extended course of therapy (21 days) would be more effective than the conventional 10-day course of therapy. All patients initially received either gentamicin or tobramycin parenterally for 48 to 72 hours, and then were prescribed an oral agent that possessed in vitro inhibitory activity for the urinary pathogen to complete the course of therapy. Duration of medication was assigned according to a table of random digits. Of the 22 women receiving the 10-day treatment 17 were cured, 4 experienced a reinfection and none had a relapse, compared to 12, 5 and 3, respectively, of 22 receiving the 21-day treatment. Analysis of the therapeutic failures did not demonstrate any superior response for either treatment program (p less than 0.75 and greater than 0.50). No statistically increased incidence of adverse drug reactions occurred in patients receiving the extended course of therapy. Our data do not support an extended course of therapy in women with acute symptomatic pyelonephritis uncomplicated by structural abnormalities.

Community-acquired bacteremic urosepsis in the elderly patients: a prospective study of 34 consecutive episodes.

A prospective study was done on the clinical, laboratory, radiological, immunological and therapeutic features of acute, symptomatic, bacteremic urosepsis in 34 consecutive, elderly patients who required hospitalization. Urinary tract infection was identified as the most common cause of gram-negative bacteremia in elderly patients admitted to a community hospital. Appropriate antibiotic therapy and a lack of serious associated medical illnesses contributed to the high survival rate. Bacteremia and shock occurring in the wake of pyelonephritis develop more commonly in elderly than in young women. In the elderly patient with bacteremia and pyelonephritis radiographic evaluation invariably demonstrates obstruction to urine flow, calculous disease or abscess. Guidelines are provided for the therapy of acute, symptomatic bacteremic urosepsis.

Acute pyelonephritis in the elderly.

We did a prospective study of the clinical, laboratory, radiologic, and therapeutic features of acute, symptomatic, bacterial pyelonephritis in 35 consecutive elderly, noncatheterized patients who required hospitalization. Pyelonephritis had been identified as the most common cause of gram-negative bacteremia in elderly patients admitted to a community hospital. Appropriate antibiotic therapy and, of equal importance, a lack of serious associated medical illnesses contributed to the 97% survival. Two features appear to distinguish acute, symptomatic, bacterial pyelonephritis in elderly women from that in young women: an increased incidence of bacteremia and septic shock. We provide guidelines for the diagnostic evaluation and antibiotic therapy of acute, symptomatic, community-acquired, bacterial pyelonephritis in the elderly.

Symptomatic pyelonephritis in elderly men.

A prospective study was carried out of the clinical, laboratory, radiologic and therapeutic features of acute, symptomatic, bacterial pyelonephritis as experienced by 12 consecutive elderly, noncatheterized men who required hospitalization. In spite of the advanced ages of the men and the inordinate frequency of bacteremia and septic shock, no patient died. "Appropriate" antibiotic therapy, supportive treatment, and, as importantly, a lack of associated "imminently" or "ultimately" fatal illnesses contributed to the 100 per cent survival rate. Guidelines are provided for the diagnostic evaluation and antibiotic therapy of community-acquired pyelonephritis in elderly men.

Hemophilus influenzae bronchitis and pneumonia.

Hemophilus influenzae is increasingly recognized as an important pathogen in a wide spectrum of diseases in adults. It is often implicated in the infectious exacerbation of chronic bronchitis, and it is a frequent cause of pneumonia in adults. The recent recognition of ampicillin-resistant strains should be a reminder to obtain beta-lactamase or antibiotic susceptibility testing when H. influenzae is isolated in specimens from patients with lower respiratory infections.
