A 64-year-old male was admitted in September 1989 with complaints of fever and muscular weakness in the extremities. A peripheral blood examination on admission revealed WBC 10,300/microliters (monocytes 32%), RBC 195 x 10(4)/microliters, Hb 7.9 g/dl, Plt 12.8 x 10(4)/microliters with trilineage dysplasia. Bone marrow biopsy was normoplastic marrow with 25.7% of monocytes including immature blasts. Cytochemical analysis of the monocytes showed positive for peroxidase and dual esterase staining. Chromosomal analysis of peripheral blood revealed 46, XY, -7, +der(1) t(1;7)(p11;p11). A diagnosis of chronic myelomonocytic leukemia was made. Hemostatic studies revealed cryofibrinogenemia, marked platelet aggregation on blood smear, hyperfibrinogenemia and a marked increase in maximal amplitude of thrombelastogram. Treatment with prednisolone and VP16, resulted in a reduction of peripheral monocytes and a disappearance of cryofibrinogen, marked platelet aggregation and a decrease in muscular weakness. Nine months after diagnosis he died of DIC, pneumonia, lung abscess and sepsis.

We assessed the frequency and clinical significance of polymicrobial infections in 31 patients with sporadic community-acquired Legionella pneumonia. Twenty-six patients were men, 5 were women and mean age was 61 years. Eighteen patients were smokers, 6 patients were chronic alcoholics and 23 had underlying diseases. Regarding severity, the illnesses were mild (two patients), moderate (seven patients) and severe (twenty-two patients). In 9 (29%) of the patients, one other etiologic agent for community-acquired pneumonia was identified in addition to the Legionella species. The distribution of one other causal agent was as follows: Mycoplasma pneumoniae, 2 patients; Chlamydia pneumoniae, 2; Chlamydia psittaci, 1; Influenza virus, 1; Streptococcus pneumoniae, 1; Klebsiella pneumoniae, 1; Pseudomonas aeruginosa, 1 patient. Because an antimicrobial agent with activity against Legionella species can also provide coverage for Mycoplasma pneumoniae. Chlamydia pneumoniae, and Chlamydia psittaci, the patients with these coinfections improved without any complications. The patient with influenzavirus coinfection became seriously ill, and the condition was complicated by disseminated intravascular coagulation, renal failure and aspergillus bronchitis. The case of Pseudomonas aeruginosa coinfection was accompanied with a lung abscess and empyema. Our experience illustrates the importance of considering polymicrobial infections in patients with sporadic community-acquired Legionella pneumonia.

Complicated community-acquired pneumonia in a previously well child is a severe illness characterised by combinations of local complications (eg, parapneumonic effusion, empyema, necrotising pneumonia, and lung abscess) and systemic complications (eg, bacteraemia, metastatic infection, multiorgan failure, acute respiratory distress syndrome, disseminated intravascular coagulation, and, rarely, death). Complicated community-acquired pneumonia should be suspected in any child with pneumonia not responding to appropriate antibiotic treatment within 48-72 h. Common causative organisms are Streptococcus pneumoniae and Staphylococcus aureus. Patients have initial imaging with chest radiography and ultrasound, which can also be used to assess the lung parenchyma, to identify pleural fluid; CT scanning is not usually indicated. Complicated pneumonia is treated with a prolonged course of intravenous antibiotics, and then oral antibiotics. The initial choice of antibiotic is guided by local microbiological knowledge and by subsequent positive cultures and molecular testing, including on pleural fluid if a drainage procedure is done. Information from pleural space imaging and drainage should guide the decision on whether to administer intrapleural fibrinolytics. Most patients are treated by drainage and more extensive surgery is rarely needed; in any event, in low-income and middle-income countries, resources for extensive surgeries are scarce. The clinical course of complicated community-acquired pneumonia can be prolonged, especially when patients have necrotising pneumonia, but complete recovery is the usual outcome.
