Knowledge of the respiratory pathogens that cause pneumonia, combined with data obtained from the initial history, physical examination, and laboratory studies, provides the framework for an empirical approach to the treatment of community-acquired pneumonia. Selection of empirical therapy is based in large part on which of three broad groups the patient belongs to: previously well young adults, adults who are older or have a history of smoking or alcoholism, or HIV-infected adults. Several newer oral agents offer subtle advantages and disadvantages when compared with traditional agents, and these must be carefully weighed when prescribing treatment.

The case fatality rate in bacteremic pneumococcal pneumonia (Pnb) has been reported to be lower in Sweden than in the United States. We retrospectively compared 231 adult Pnb patients in Stockholm (STO), Sweden, with 107 patients infected with the same serotypes or groups in Huntington, WVa (HWV). The total case fatality rate was 11/231 (5 percent) in STO versus 28/107 (26 percent) in HWV (p < 0.001), being significantly lower in STO for all age groups. Patients from HWV more often had preexisting chronic diseases, while alcoholism was more prevalent in STO. The case fatality rate was similar among alcoholics in STO and HWV, while it was much higher in nonalcoholic patients with chronic diseases in HWV (22/73;30 percent) than in STO (2/88;2 percent) (p < 0.001). No bias was found that could account for more than a small part of the higher case fatality rate in HWV. Thus, underlying chronic diseases in HWV accounted for some of the increased risk of death in this patient group. However, the major part of the difference in death rates between HWV and STO remains unexplained.

An outbreak of serotype 1 Streptococcus pneumoniae infection involving both adults and children occurred in central Australia during the winter months of 1991. Eighteen patients, mainly Aboriginal men, presented with culture-positive serotype 1 bacteraemic pneumonia. In this group, 11 of 12 adults for whom medical records were available were alcohol dependent. Thirteen children who were separately studied were hospitalised with acute lower respiratory tract infection: none had bacteraemia but all had upper airway colonisation by type 1 pneumococci. Antibiotics taken by 8 of the 13 children before admission to hospital may have compromised the isolation of type 1 pneumococci from blood cultures. Since the availability of antibiotics, epidemic pneumococcal infection is infrequent and has not been reported in Australia. In three outbreaks of type 1 disease recorded elsewhere crowding and alcoholism were identified as contributory factors. In the 16 month period before this outbreak none of 162 strains of pneumococci isolated from blood (32 strains) and nasopharyngeal secretions (130 strains) from Aborigines with acute lower respiratory tract infection and meningitis in the Alice Springs region were serotype 1 organisms.

A 69-year-old alcoholic man with pneumonia and sepsis due to Aeromonas hydrophila is presented. He died of suffocation by a copious amount of hemoptysis six hours after his first symptoms of abdominal pain, diarrhea and dyspnea. Aeromonas hydrophila was isolated from blood and bronchial secretion. A fulminant form of pneumonia could develop in patients with predisposing underlying conditions such as alcoholism with chronic hepatitis and diabetes mellitus. Aeromonas hydrophila pneumonia may be characterized by hemoptysis and rapid clinical deterioration with a high mortality rate.

327 and 736 protocols of postmortem examinations from Moscow hospitals N 31 and 57, respectively, were evaluated statistically. The quality of clinical diagnosis of pneumonia was examined. Pneumonia caused death in 26.3 and 21.1% of cases in Moscow hospitals 31 and 57, respectively. Besides subjective reasons which were the main cause of diagnostic mistakes, there were such factors as poor condition of patients, atypical pneumonia course, alcoholism.

A 66-year-old man with a history of chronic alcoholism presented with Kussmaul respirations following several days of fasting accompanied by vomiting, in the presence of continued ethanol intake. He was subsequently found to have a serum glucose level of <20 mg/dL and an anion gap of 36. Despite his profound hypoglycemia, he was fully alert with no obvious neurological deficits. He recovered without incident with intravenous saline, dextrose, thiamine, and antibiotics for a bacteremic pneumonia. He had no evidence of hypoxemia, hypotension, or other features of sepsis. Alcoholic ketoacidosis in the setting of hypoglycemia is discussed. If the serum glucose level is less than the anion gap, the diagnosis of alcoholic ketoacidosis should be considered.

Despite the fact that the epidemiology of community-acquired pneumonia and nosocomial Legionella infection is well known, there are no specific reports dealing with severe cases of Legionella pneumophila pneumonia admitted to intensive care units. We undertook a prospective study upon 84 patients with a reliable diagnosis of L. pneumophila pneumonia that required ICU admission. The study assessed the prognostic factors, clinical, radiological and outcome variables of both nosocomial (n = 33) and community-acquired (n = 51) cases of L. pneumophila pneumonia. The following variables were more common in nosocomial acquired as compared to community-acquired Legionella pneumonia: Chronic obstructive pulmonary disease (COPD) (64 versus 41%), cardiac disease (39 versus 10%), chronic renal failure (21 versus 4%), alcoholism (54 versus 18%), septic shock (33 versus 16%), and unilateral chest X-ray involvement (61 versus 39%). The crude mortality rate in this study was 30% (25 of 84) with no differences when comparing mortality between nosocomial (9, 27%) to community-acquired (16, 31%) types. The univariate analysis showed that cardiac disease, diabetes mellitus, creatinine > or = 1.8 mg/dl, septic shock, chest X-ray extension, mechanical ventilation, hyponatremia < or = 136 mEq/L, PACO2/FIO2 < 130, and blood urea levels > or = 30 mg/dl were factors related to poor outcome. On the other hand, the following two variables were related to better outcome: adequate treatment for Legionella and pneumonia improvement. The logistic regression analysis demonstrated that APACHE II score > 15 at admission (RR: 11.5; 95% CI 1.75 to 76.1; p = 0.025), and serum Na levels < or = 136 (RR: 21.3; 95% CI 1.11 to 408; p = 0.023), were the only independent factors related to death. On the other hand, improving pneumonia is associated with better outcome in Legionnaires' disease than for patients not having improving pneumonia (RR: 0.019; 95% CI: 0.036 to 0.106; p < 0.0001). A better understanding of the prognostic factors in cases of severe Legionella pneumonia will optimize our therapeutic approach in this disease and help to decrease both its mortality and morbidity rates.

Streptococcus pneumoniae is an infrequent cause of infectious endocarditis in adults. In the past 2 years, however, we have encountered several cases at our institution, and additional cases have been reported in the literature. This infection typically follows pneumonia in the setting of chronic alcoholism and may additionally be complicated by meningitis. Less commonly, pneumococcal endocarditis occurs in other hosts or follows primary infection at other extrapulmonary sites. In such cases, the diagnosis may be initially missed, with a resultant delay in institution of appropriate therapy. Moreover, there are controversies regarding the optimal therapy for infections of this nature in the era of penicillin resistance. Since a comprehensive review of this topic has not been published since 1990, we reviewed cases of pneumococcal endocarditis in the penicillin era, with particular attention to disease recognition, the role of echocardiography, and the dilemmas surrounding medical and surgical therapeutic interventions.

Carbohydrate-deficient transferrin (CDT) is reported to have a higher specificity in alcoholism than conventional markers. As the morbidity and mortality rates amongst chronic alcoholics are raised following trauma, the objective was to investigate if CDT could be used to predict prolonged intensive care unit (ICU) stay and an increased morbidity in patients with multiple injuries admitted to the ICU. In this prospective double-blind study, 66 traumatized male patients were transferred to the ICU following admission via the emergency room and operative management. Blood samples for CDT determination were taken upon admission to the emergency room, the ICU and on days 2 and 4 following admission. The patients were allocated a priori to two groups: high CDT group (CDT >20 U/l on admission to the emergency room) and low CDT group (CDT < or = 20 U/l). CDT values were determined by microanion-exchange chromatography and radioimmunoassay. Thirty-six patients had an elevated CDT value on admission to the emergency room. The high CDT group had a significantly prolonged ICU stay (median high CDT group: 13 davs; median low CDT group: 5 days). Major intercurrent complications, such as alcohol-withdrawal syndrome, tracheobronchitis, pneumonia, pancreatitis, sepsis, and congestive heart failure, were significantly increased in the high CDT group. The increased risk of pneumonia in the high CDT group may be related to the significantly increased period of mechanical ventilation. As high CDT values were associated with an increased risk of intercurrent complications and a prolonged ICU stay, it seems reasonable to use CDT as a marker in intensifying research work into preventing alcoholism-associated complications.
