We investigated the late infections of 400 consecutive liver transplantations performed in 368 patients. After a mean follow-up of 45 months, a total of 180 late infections occurred in 110 liver recipients. Frequent agents were CMV, enterococcus, candida and staphylococcus. Pneumonia was the most dangerous late infection with a high mortality rate. Late infections were responsible for ten deaths that were all caused by atypical pneumonia. The majority of late infections appeared during the first year after liver transplantation. Thereafter, the risk of infection declined significantly.

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.

Tularemia pneumonia may complicate the various clinical presentations of tularemia, or present as an uncommon zoonosis. Approximately 200 cases of tularemia are reported in the United States per year, and 10% to 20% present with pneumonia either as a primary event or as a complication of ulceroglandular or typhoidal tularemia. Tularemia pneumonia also occurs with the other tularemic forms, glandular, oculoglandular, and oropharyngeal tularemia as a result of secondary bacteremic spread to the lungs. Pneumonia usually occurs within 2 days to months after infection. The mortality rate of primary tularemic pneumonia and pneumonia complicating typhoidal tularemia is high. The clinical and roentgenographic presentations of tularemia pneumonia are highly variable and is one of the zoonotic atypical pneumonias. Tularemic pneumonia may mimic fungal and bacterial pneumonias, tuberculosis, or malignancy. The diagnosis of tularemic pneumonia should be considered in any patient presenting with an atypical pneumonia with the finding of an ulcer and/or lymphadenopathy and a history of outdoor activity. Serum agglutination tests and ELISA are the basis of serological diagnosis. Francisella tularensis can be cultured from the sputum, skin ulcer, pleural fluid, and the lymph nodes, but cultures should not be obtained because of the danger to laboratory personnel. The drug preferred for treatment of tularemic pneumonia is streptomycin for 1 to 2 weeks.

35 children between 9 months and 12 years of ages were given 9.1 to 12.2 mg/kg of azithromycin (AZM) once a day for 3 days. In the treatment of pediatric infectious diseases, we studied pharmacokinetics, efficacy and safetiness of AZM. After administration of 10 mg/kg/day of AZM for 3 days, the elimination half-life was calculated to be 3.8 +/- 16.3 hours (n = 6, mean +/- S.D.). The excretion rate of AZM in the urine within 120 hours of administration was 9.0 +/- 2.3% (n = 5). For the evaluation of efficacy of AZM, we treated 33 cases of children with pharyngotonsillitis, bronchitis, mycoplasma bronchitis, pneumonia, mycoplasma pneumonia, atypical pneumonia, and SSTI. The efficacy rate of these cases were 93.9%. 6 strains of bacteria were identified as causative agents. All strains were eradicated upon the treatment. One case of elevated GOT and GPT and two cases of elevated GPT were observed. No clinical adverse reactions were observed. In conclusion, AZM was useful for the treatment of pediatric infectious diseases were examined.

A prospective study was undertaken to assess the usefulness of serum adenosine deaminase (ADA) activity in the aetiological diagnosis of 75 patients (mean age 58 years) with community-acquired pneumonia who required hospitalization. Measurements of ADA were also carried out in 35 healthy subjects (mean age 52 years). The serum ADA activity in patients with typical bacterial pneumonia (TBP) was 21 +/- 7 IU/l and in controls 22 +/- 9 IU/l. In 43 patients with atypical pneumonia (AP), ADA levels (43 +/- 23 IU/l) were significantly higher than in the previously related groups (p < 0.001). Analysis within the group of atypical pneumonia showed significant differences for infections caused by Coxiella burnetii (61 +/- 19 IU/l, p < 0.001), Mycoplasma pneumoniae (44 +/- 26 IU/l, p < 0.001) and Legionella pneumophila (39 +/- 15 IU/l, p < 0.05), as compared with patients with bacterial pneumonia and normal control subjects. We conclude that serum ADA in patients with community-acquired pneumonia requiring hospitalization may provide useful additional diagnostic information on the aetiology of pulmonary infection.

Psittacosis, caused by Chlamydia psittaci, is mainly associated with an atypical pneumonia. We report a case of psittacosis where onset of respiratory symptoms was soon followed by the onset of focal neurological signs, a very uncommon feature. Despite adequate treatment with erythromycin, the patient relapsed when re-exposed to a sick pet bird. A prolonged course of doxycycline led to resolution of the pneumonia, but it is important to recall that successful management must also include the elimination of the precipitating cause of the infection.

The efficacy and safety of grepafloxacin in treating patients with community-acquired pneumonia (CAP) was assessed in an open-label, noncomparative study. Patients (N = 273) received grepafloxacin 600 mg QD for 10 days. A total of 237 patients (87%) completed the study. In assessable patients, the clinical success rate at follow-up (4 to 6 weeks after the last dose) was 89% (211/238 patients). In microbiologically assessable patients, the eradication rate at follow-up was 95% (86/91 isolates). Grepafloxacin was highly effective in the treatment of bacterial CAP caused by Streptococcus pneumoniae (irrespective of penicillin susceptibility), Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis, and Staphylococcus aureus and in the therapy of atypical pneumonia caused by Mycoplasma pneumoniae and Legionella pneumophila. Grepafloxacin was well tolerated, with the most frequently reported drug-related adverse events being taste perversion and nausea. Grepafloxacin 600 mg QD for 10 days was highly effective and well tolerated in the treatment of patients with CAP.

Community-acquired pneumonia (CAP) in the elderly has a different clinical presentation than CAP in other age groups. Confusion, alteration of functional physical capacity, and decompensation of underlying illnesses may appear as unique manifestations. Malnutrition is also an associated feature of CAP in this population. We undertook a study to assess the clinical and nutritional aspects of CAP requiring hospitalization in elderly patients (over 65 yr of age). One hundred and one patients with pneumonia, consecutively admitted to a 1,000-bed teaching hospital over an 8-mo period, were studied (age: 78 +/- 8 yr, mean +/- SD). Nutritional aspects and the mental status of patients with pneumonia were compared with those of a control population (n = 101) matched for gender, age, and date of hospitalization. The main symptoms were dyspnea (n = 71), cough (n = 67), and fever (n = 64). The association of these symptoms with CAP was observed in only 32 patients. The most common associated conditions were cardiac disease (n = 38) and chronic obstructive pulmonary disease (COPD) (n = 30). Seventy-seven (76%) episodes of pneumonia were clinically classified as typical and 24 as atypical. There was no association between the type of isolated microorganism and the clinical presentation of CAP, except for pleuritic chest pain, which was more common in pneumonia episodes caused by classical microorganisms (p = 0.02). This was confirmed by a multivariate analysis (relative risk [RR] = 11; 95% confidence interval [CI]: 1.7 to 65; p = 0.0099). The prevalence of chronic dementia was similar in the pneumonia cohort (n = 25) and control group (n = 18) (p = 0.22). However, delirium or acute confusion were significantly more frequent in the pneumonia cohort than in controls (45 versus 29 episodes; p = 0.019). Only 16 patients with pneumonia were considered to be well nourished, as compared with 47 control patients (p = 0.001). Kwashiorkor-like malnutrition was the predominant type of malnutrition (n = 65; 70%) in the pneumonia patients as compared with the control patients (n = 31; 31%) (p = 0.001). The observed mortality was 26% (n = 26). Pleuritic chest pain is the only clinical symptom that can guide an empiric therapeutic strategy in CAP (typical versus atypical pneumonia). Both delirium and malnutrition were very common clinical manifestations of CAP in our study population.

In a previous prospective study, Streptococcus pneumoniae was identified as the causative agent in 148 (42.8%) of 346 adult patients hospitalized over the course of one year with community-acquired pneumonia (CAP) in the Soroka Medical Center, Beer-Sheva, Israel. The present study characterizes those cases in which Streptococcus pneumoniae was the only pathogen and those in which additional etiological agents were identified. Pneumococcal CAP was diagnosed by standard blood cultures or positive serological tests by one of two laboratory methods. In 100 (67.6%) patients, at least one other etiological agent of CAP was identified in addition to Streptococcus pneumoniae. Compared with patients who were not infected by Streptococcus pneumoniae, patients with Streptococcus pneumoniae CAP were older and had a higher rate of comorbidity (39.5% vs. 29.8%). Streptococcus pneumoniae CAP had a more severe clinical course and a higher mortality rate, especially when Streptococcus pneumoniae was the only pathogen. Community-acquired pneumonia due to Streptococcus pneumoniae only was more similar in its clinical manifestations to classic typical pneumococcal pneumonia. When an additional etiological agent was identified, the clinical characteristics could not be distinguished from those of atypical pneumonia. It is concluded that Streptococcus pneumoniae remains the principal cause of CAP in this region. The frequency of additional etiological agents of CAP and the difficulty in differentiating clinically between cases due to Streptococcus pneumoniae only and those due to Streptococcus pneumoniae plus other organisms necessitates initial empirical treatment that covers Streptococcus pneumoniae as well as other causative agents of atypical pneumonia.

The efficacy of a 5-day regimen consisting of 500 mg in a single dose on the first day followed by 250 mg once daily for 4 consecutive days was compared with that of a 3-day course of azithromycin given in single daily doses of 500 mg for treatment of atypical pneumonia. Adult patients hospitalized with atypical pneumonia in the years 1990 to 1993 were studied retrospectively. For each patient, the medical history, laboratory data, the results of serological tests, chest radiographs and treatment outcome were reviewed. Out of 148 patients with atypical pneumonia, 40 were treated with azithromycin for 5 days (Group 1) and 41 for 3 days (Group 2). The success rate in Group 1 was 80% (32 patients). Eight patients did not respond to treatment: 5 had significant complement fixing antibody titers to adenovirus and in 3 the etiology was unknown. The success rate in Group 2 was 88% (36 patients). Azithromycin was ineffective in all 3 patients with adenoviral pneumonia, in 1 patient with Q fever, and in 1 patient with no identified pathogen. Azithromycin is equally effective as treatment of atypical pneumonia in adult patients if given for 3 or 5 days at the same total dose.
