Some studies were carried out on the use of 9,3"-diacetylmidecamycin (MOM) dry syrup, a new macrolide antibiotic preparation, in the treatment of children. The results are summarized below. 1) A single oral dose of 10 mg/kg of the MOM dry syrup was administered to 1 child at 2 hours after a meal. The peak concentration of the antibiotic in the blood was 0.88 micrograms/ml and occurred at 1 hour after administration. At 2 hours the concentration had fallen to 0.59 microgram/ml, and after 4 hours the blood level was already below the minimum detectable concentration (0.5 microgram/ml). During the first 6 hours after the administration, 6.7% of the MOM was recovered in the urine. 2) The MOM dry syrup was orally administered to 4 pneumonia patients (including 2 cases of mycoplasmal pneumonia) for 7 days at a daily dosage of 15.2--20.5 mg/kg (divided into 3 equal doses). The therapeutic results were excellent in 2 cases, good in 2 cases and poor in none. 3) No side effects such as exanthema were observed to occur. In 1 case only, there was a mild and temporary elevation in the laboratory test values for total bilirubin, GOT and GTP. 4) All 4 of the pneumonia patients found the MOM dry syrup to be easy to ingest. The taste and odor of this antibiotic preparation were judged to be sufficiently palatable to permit convenient use in the treatment of children.

Sera from six outbreaks of legionellosis and four outbreaks of pneumonia of other etiologies were tested with the indirect immunofluorescence assay (IFA) as currently performed. The current IFA is at least as sensitive as the original test in detecting cases of Legionnaires disease (78 to 91%). By using Center for Disease Control criteria for a positive (fourfold increase in titer during convalescence to greater than or equal to 128) or presumptive (single titer greater than or equal to 256) serological test, the specificity exceeded 99%. No cross-reactions against Legionella pneumophila antigens were observed among sera from epidemic cases of Q fever, tularemia, and psittacosis; the only positive L. pneumophila IFA titer among the epidemic Mycoplasma pneumonia sera was reduced to a negative titer with an immunosorbent extracted from Escherichia coli strain O13:K92:H4. The slight increase in specificity (to 100%), however, was offset by a slight decrease in sensitivity. The sensitivity of the IFA was maximal when a conjugate that detected immunoglobulins G, M, and A was used. IFA titers were not significantly altered by replacing the monovalent serogroup 1 antigen with a polyvalent antigen (serogroups 1 through 4) nor by the presence of rheumatoid factor or heat-labile serum factors.

Pulmonary function was studied in 15 patients who had clinically and radiologically recovered from proven Mycoplasma pneumoniae pneumonia, 21 weeks (mean) previously. Ten patients were tested again 43 weeks (mean) later. Lung volumes and measurements of airways resistance were generally normal. Transfer factor and diffusion constant were initially reduced in the smokers and significantly improved between the two studies, being normal at the second testing. It is suggested smokers take longer to recover from mycoplasma pneumonia although all cases had returned to normal a year after the illness.

The effects of tylosin tartrate and tiamutilin were examined in pneumonias induced experimentally in neonatal piglets with a homogenate of pneumonic pig lung, obtained from pigs with naturally acquired enzootic pneumonia. The homogenate contained mycoplasmas, including Mycoplasma hyopneumoniae (M suipneumoniae) and M hyorhinis, and certain bacteria and viruses. The experimental pneumonias generally resembled mycoplasmal pneumonia histologically but were complicated by aspiration pneumonia in some animals. both tylosin tartrate (50 mg/kg) and tiamutilin (10 mg/kg) administered orally twice daily for 10 days, beginning 14 days after intranasal infection, significantly reduced the incidence and severity of macroscopical pneumonic lung lesions. M hyopneumoniae could be isolated from the lungs of the unmedicated piglets, but not from drug-treated piglets. The numbers of M hyorhinis, Acholeplasma granularum, Haemophilus parasuis, Pasteurella multocida and P haemolytica in the lung tissue of the infected piglets were significantly reduced by drug therapy. The role of bacterial in the experimental infection appeared to be that of secondary invaders.

Mycoplasma pneumonia usually follows a benign course and the patient does not require hospitalization. The present report summarizes the feature of eight children admitted for a moderately severe pneumonia during an epidemic of Mycoplasma pneumoniae in Victoria. All children were previously healthy. The usual presenting symptoms included cough, fever, lethargy, and weight loss. All children had moderately severe respiratory distress and physical signs in the chest consistent with extensive parenchymal involvement. Half of this group had radiological evidence of a small pleural effusion. Complement fixation titres for Mycoplasma pneumoniae in paired samples confirmed the diagnosis. Clinical and radiological resolution was complete after one to three months. It is suggested that severe mycoplasma pneumonia may be more common than previously appreciated.

An 8-year-old girl with a cerebral infarction and pneumonia developed the acute hemiparesis associated with clinical and serologic evidence of Mycoplasma pneumonia infection. Mycoplasma complement fixation titers increased from 1:1,024 on the tenth day of illness to 1:greater than 16,384 at three weeks and subsequently decreased to 1:512 at seven weeks. Total resolution of her facial weakness, hemiparesis, dysphagia and dysarthria occurred by eight weeks.

Pneumonia due to Mycoplasma pneumoniae may present at any age after age five. The clinical picture varies from an acute febrile illness to a prolonged disease with affected general state and little pulmonary involvement. The radiological picture is varied but the alveolar pattern predominates, making the differential diagnosis with the bacterial pneumonias difficult. However, in the presence of an interstitial or mixed pattern, especially if generalized, pneumonia due to Mycoplasma pneumoniae must be suspected. This radiological picture is particularly frequent in elderly patients, often affected by other diseases able to induce immunodepression. In such patients the radiology and the unspecific clinical picture frequently cause diagnostic delays. The presence of a pneumonia with multisystem involvement (blood, nervous system, joints, etc.) should suggest the possibility of Mycoplasma pneumoniae infection.

Clinical effect of acetylspiramycin, one of macrolide antibiotics, primary atypical pneumonia and serologically proven Mycoplasma pneumonia in children was studied. Twenty-four cases of these pneumonia (PAP 11, MP 13) in children were selected and acetylspiramycin was given in dose of approximately 30 mg/kg/day orally. Clinical response was evaluated in terms of improvement in fever, cough and chest X-ray. Clinical response was excellent in 4, good in 5, fair in 14 cases and none in 1 case. No definite adverse effect was observed, however 3 cases showed skin rashes. Two cases showed evanescent small erythematopapulous rash and 1 case developed urticaria on the 2nd to 4th day after this drug was given. These skin rash seemed one of the manifestation of Mycoplasma infections, rather than adverse side effect. One case showed elevated transaminase activity before acetylspiramycin was given and improved on the 2nd week, although this drug was continued. No other side effect was observed. We were able to use acetylspiramycin only in the form of 200 mg tablet and difficulty of the administration was encountered in children under 5 years of age. Other form (dry syrup, etc.) of this drug should be considered for the clinical use in children. In conclusion, acetylspiramycin was effective and safe for the treatment of primary atypical pneumonia and Mycoplasma pneumonia.

The natural and treated course of Mycoplasma pneumoniae is generally satisfactory. Only a few cases with fatal outcome have been reported, mainly in immunosuppressed and debilitated patients. The case is reported of a healthy young woman admitted with acute respiratory failure, who developed diffuse interstitial fibrosing pneumonia followed by refractory hypoxemia. The diagnosis of Mycoplasma pneumoniae pneumonia was at first suspected from an elevated specific titer in the standard complement fixation test, and then confirmed in the immunofluorescence study by the presence of granular deposits (mycoplasma) in the macrophages of lung tissue. The functional impairments associated with this unusually malignant evolution are discussed.

We studied methacholine bronchial inhalation challenge in 12 patients at 4th week and 12th week after recovered from Mycoplasma pneumoniae pneumonia, compared with 12 healthy subjects as controls. The aerosolized methacholine was produced by an atomized nebulizer of the Provocationtest I, Pari-Starnberg, Germany and the aerosol was kept into a reservoir bag. Then, it was inhaled slowly by a subject. Increasing concentration of methacholine solutions (0, 0.5, 1, 5, 10, and 25 mg/ml) were used. The results revealed that 67% of the patients had bronchial reactivity to methacholine at the first time of challenge with a mean concentration of methacholine producing a fall in FEV1 of 20% from baseline (PC20) of 12.3 +/- 6.44 mg/ml. Fifty percent of the patients were still positive to the test on the second time of challenge with a mean PC20 of 20.1 +/- 6.89 mg/ml. None of the healthy subjects had bronchial hyperreactivity (PC20 > 25 mg/ml). Two patients experienced wheezing and asthmatic attacks requiring bronchodilator therapy during acute phase pneumonia. They were also diagnosed as having bronchial asthma for the first time. Many patients had prolonged coughing during the recovery phase lasting more than 4 weeks. This prolonged coughing seemed to have a correlation with the development of bronchial hyperresponsiveness (BHR). We concluded that M. pneumoniae could induce BHR which may be transient or persistent. The effect of mycoplasma respiratory tract infection may result in airway inflammations and asthmatic attacks.
