During two epidemics of influenza A infection in Stockholm 1969-72, 249 cases were selected for a study on the effect of bacterial superinfection. Bacterial involvement was demonstrated through cultures and serologic reactions. The occurrence of C-reactive protein in increased amount in serum was significantly more common in the group which had the strongest indication of bacterial infection. An increased duration of fever, and a higher incidence of pneumonia, leukocytosis and erythrocyte sedimentation rate over 50 mm/l h was also the rule in cases with bacterial involvement. During both epidemics the bacteria most often involved were pneumococci.

The role of anaerobic and aerobic microorganisms in the genesis of pneumonia or lung abscess in patients with historical, clinical, and radiologic findings suggestive of aspiration was compared to their role in similar patients without these findings. Bacterial specimens were obtained by transtracheal aspiration or thoracentesis. Anaerobes were isolated in 100% of the patients who were aspiration-prone as contrasted with only 20% of those who were not. Isolation of a single species or no growth was more common in the nonaspiration group, whereas multiple isolates were more common in the aspiration group. Patients with lung abscesses were treated with penicillin and all of them responded clinically, despite occasional recovery from the culture specimen of penicillin-resistant organisms. This suggests that lung abscess may be the result of a synergistic bacterial infection.

The effect of pneumonia induced by Mycoplasma pulmonis in mice on the resistance of the lung to additional bacterial infection was examined. The effect of pneumonia induced by Sendai virus on the resistance of mice to M. pulmonis was also investigated and compared with the effect of Sendai virus on resistance to Staphylococcus aureus. Sendai virus infection decreased subsequent resistance to M. pulmonis in proportion to the virus dose. Decreased resistance to subsequent S. aureus and M. pulmonis infection was greatest at about the same time after inoculation of virus and was related to virus-induced lesions. Besides affecting the resistance of mice to subsequent mycoplasma infection, Sendai virus could enhance an existing mycoplasma infection. Pneumonia induced by M. pulmonis did not decrease resistance to subsequent bacterial infection. The mechanism whereby Sendai virus decreases host resistance is therefore similar for bacteria and mycoplasmas, but pneumonia induced by mycoplasmas does not have the same effect.

Clindamycin-2-phosphate (7(S)-chloro-7-deoxylincomycin-2-phosphate) is a new semi-synthetic antibiotic. It is recognized that the drug itself is inactive against bacteria in vitro but it is hydrolyzed rapidly to active clindamycin, drug intramuscular or intravenous administration. Clindamycin-2-phosphate was administrated intravenously to seven patients with infections, except one intramuscularly, 300 approximately 600 mg, every 8 or 12 hours a day, for 2 approximately 12 days. Three patients (1 bacterial pneumonia, 1 chronic bronchitis and 1 urinary tract infection due to E. coli) recovered from their infection; one patient (bacterial infection in bronchiectasis) partially responded; and three patients (1 urinary tract infection due to E. coli, 1 pneumonia due to Mycoplasma pneumoniae and 1 patient with mycoplasmal pneumonia and acute biliary tract infection) failed to respond to the drug. No remarkable side effect was noted except pain at intramuscular injection site in one patient.

A 40-year-old woman who had recently undergone kidney transplantation was succesfully treated for diffuse influenza virus pneumonia. The illness was acute, with rapid onset, high fever, nonproductive cough, dyspnea, cyanosis, crepitations and rales over both lung bases, and associated arterial hypoxemia, leukopenia, and thrombocytopenia. Prophylactic use of antibiotics to prevent superimposed bacterial infection and reduction of immunosuppressive therapy to minimal dosage during the critical phase of the respiratory infection contributed to the patient's survival. An episode of graft rejection was reversed by resumption of immunosuppressive therapy at standard dosage levels.

Infections are an almost inevitable complication of human bone marrow transplantation and account for the majority of deaths in transplant recipients. Even prior to the initiation of the transplantation procedure, patients may present with infections complicating previously unsuccessful chemotherapy for hematological malignancy or aplastic anemia. Nevertheless, these pre-transplantation infections should not exclude the possibility of bone marrow transplantation if they can be successfully controlled with specific antimicrobial therapy and necessary adjunctive measures. The immediate post-transplantation period prior to engraftment is characterized by severe marrow aplasia that results from high-dose chemotherapy and total-body irradiation. Infections are primarily septicemias and localized processes caused by bacteria and fungi and their incidence increases as the intensity of immunosuppression is escalated. The high mortality associated with bacterial septicemia makes early, empirical antibacterial therapy mandatory. However, the reduction in mortality from bacterial infection resulting from such an aggressive approach may be offset by a higher mortality from invasive fungal infection, especially in patients with prior fungal colonization and undergoing prolonged conditioning therapy. Thus, until more specific and sensitive tests for the diagnosis of invasive fungal infection become available, empirical intravenous amphotericin should be considered in patients who are persistently febrile and deteriorate clinically in the face of appropriate antibacterial therapy. Interstitial pneumonia associated with severe GVHD is the major infectious complication after successful marrow engraftment and is the most significant barrier to long-term survival. Trimethoprim-sulfamethoxazole is effective prophylaxis against interstitial pneumonia due to Pneumocystis carinii, but one half of the patients still develop a pneumonitis either associated with CMV or of unknown etiology. Mortality from interstitial pneumonia is related to prior radiation therapy while survival is associated with a four-fold rise in CMV CF antibody titer. The latter observation supports the need to investigate passive immunization with CMV antibody as a means of preventing some interstitial pneumonias. Despite the progress made in many areas of human bone marrow transplantation, the majority of graft recipients still die of infectious complications. Thus, new approaches to the management of infections in transplant recipients are urgently needed. Better-tolerated oral nonabsorbable antibiotics, laminar-air-flow rooms, granulocyte transfusions, and chemotherapy and immunotherapy for CMV are among the prophylactic and therapeutic measures that must be critically evaluated in well-controlled, prospective studies. Continued assessment of the infectious complications of bone marrow transplantation is a critical aspect of any ongoing transplant program, not just a research goal...

Ten cases of cholecystitis with severe lymphocytic reactions were selected among serially examined 131 cases of cholecystitis or/and cholelithiasis. Gram-negative bacterial infection, especially E. coli and K. pneumonia seemed to be related as the cause of these severe lymphocytic reactions, but the gallstone revealed no definite influence. We would like to separate the cases with severe lymphocytic reactions as a lymph follicular cholecystitis and consider the possibility of a gram-negative bacterial infection in bile.

Complications are the major causes of illness and death after burning and most of them stem from the burn wound. Their origin and importance are reviewed with emphasis on problems and growing points in knowledge. Fluid leakage from the circulation into the burn is the cause of hypovolemic shock, but the underlying permeability changes in the burn are only partly understood. Other nonbacterial complications include acute cardiac failure, acute anemia, hemolytic jaundice, renal failure, encephalopathy, complex hypermetabolic effects including pseudodiabetes, gastric and duodenal ulceration, deep vein thrombosis and pulmonary embolism, pulmonary and glomerular microthrombosis, hepatic jaundice, and arterial thrombosis. Involvement of the airway in conflagrations carries special hazards like glottic edema and inhalation of irritant fumes. Nowadays, bacterial causes are dominant and these remain the main challenge. Bacterial infection and invasion of the burn are usually responsible for septicemia, bronchopneumonia, and pyelonephritis although other sources also contribute. Indirect manifestations of septicemia include paralytic ileus, acute gastric dilatation, toxic myocarditis, and some cases of renal failure. Therapeutic complications like agranulocytosis, thrombocytopenia, and colitis occur at times. High concentrations of oxygen given therapeutically can produce fatal aseptic hypoxic pneumonitis.

The reduction of nitroblue tetrazolium (NBT) dye by neutrophils from 379 patients with infectious diseases and 268 controls has been examined. The mean NBT score was 29.8% (72.3% positive tests) in the 231 patients with non-tuberculous bacterial infections, 9.7% (28.1% positive tests) in the 135 patients with viral infections 5.3% (1.5% positive tests) in the controls. Positive tests were demonstrated in 1 of 7 patients with tuberculosis and in 4 of 6 with mycoplasma pneumonia. Patients with urinary tract infections or septicemia had the highest percentage of positive tests, particularly when the infections were caused by gram-negative bacteria. In acute bacterial infection, the 176 patients who had not received any antibacterial therapy prior to testing had a significantly higher mean NBT score and proportion (77.8%) of positive tests than the remaining 55 pretreated patients (54.5%). Recent antibiotic treatment seriously invalidates the NBT test results. In acute viral infection, 29 of the 38 positive tests were obtained from patients with acute hepatitis (mean score 20.0%) or infectious mononucleosis (mean score 9.3%). When evaluating the test results, special attention should be paid to patients with hepatitis. Endotoxin stimulated NBT tests disclosed normal enhancement of NBT reduction by neutrophils from the patients and the controls. Cautiously interpreted, the NBT reduction by neutrophils from the patients and the controls. Cautiously interpreted, the NBT test results may be useful as an adjunct in the differential diagnosis of major bacterial and viral infections.
