The objective of this investigation was to determine whether Chlamydia pneumoniae was involved in an outbreak of respiratory disease among military recruits, 92 patients (average age 20.1 years) were included in the study if they had a sore throat or cough for more than 1 week. In addition to sore throat and cough, fatigue, headache, dyspnoea and vertigo were the most frequent symptoms. The patients received standard treatment with 100 mg of doxycycline b.i.d. for 14 days. In 38.8% of cases symptoms were alleviated after 1-2 weeks of treatment, and in 22.4% of cases after 2-3 weeks of treatment. Pretreatment throat washings and sera were sampled for Chlamydia. Sera were drawn for Chlamydia, Mycoplasma and adenovirus serology. Cell culture (Hep-2) and 3 different serological methods-microimmunofluorescence (MIF), enzyme immunoassay with a recombinant glycoconjugate antigen (r-EIA) and immunoperoxidase assay (IPA)-were used. Cell culture was found to have too low a sensitivity to be of diagnostic value. Acute infection was demonstrated in 13% by MIF IgM and in an additional 21% by MIF IgG (titre rises). Enzyme immunoassay IgM was found in 17% and IPA IgM in 19% of individuals without MIF IgM antibodies. Microimmunofluorescence was found to be the most useful test for serodiagnosis. The combination of serological methods showed that 40 out of 52 (76.9%) had an acute infection with possible chlamydial aetiology. In conclusion, methodological improvements are necessary for the aetiological diagnosis of chlamydial respiratory infections.

H1 antihistamines have been shown to have antitussive effects in patients with asthma and postnasal drip. In Japan, no study has been performed to determine whether orally administered oxatomide, H1 antihistamine, can reduce the chronic cough seen in patients with post-upper-airway infection (postinfection). Patients who had chronic cough of more than three weeks' duration and a history of post-upper-airway infection took part in the study. None had any history of nasal disease, gastroesophageal reflux, bronchial asthma, or other chronic pulmonary disease. All patients were non-smokers, and none used ACE inhibitors. They had normal CRP concentrations, peripheral white blood cell and eosinophil counts, serum IgE concentrations, titers of cold agglutinins and antibodies to Mycoplasma pneumoniae, chest roentgenograms, and respiratory function tests. A prospective randomized, open design was used. The effect of one week of treatment with dextromethorphan (D) or with D plus oxatomide (D + O) on the severity of cough, as estimated by cough diary, were examined. Twenty-two patients entered the study, and 20 were eligible for efficacy and side-effect analyses. Nine patients receiving D and 11 receiving D + O completed the protocol. Patients' characteristics before the start of the study, such as severity and duration of cough, and laboratory data, were not significantly different between the two groups. From trial day 5 to 7, improved rates of cough were significantly higher with D + O than with D alone (p < 0.05). Combination therapy with oxatomide and dextromethorphan reduces subjective perception of cough as estimated by cough diary. These results suggest that oxatomide, H1 antihistamine may improve chronic cough in patients with post-upper-airway infection.

A clinical, bacteriological, serological and patho-anatomical study was carried out on 12 goats surviving the acute stage of contagious caprine pleuropneumonia (CCPP), experimentally produced with Mycoplasma capricolum ssp. capripneumoniae (M. capripneumoniae), with the major aims of investigating the chronic stage of the disease and elucidating the possibility of a carrier state beyond the acute fulminant phase. The goats were killed 9, 16, 82 or 126 days after the onset of acute clinical signs. On day 9, clinical signs included low grade fever and persistent coughing. Thereafter, only intermittent coughing was recorded. Serum titres of complement-fixing antibodies to M. capripneumoniae were high at the period of fever but dropped thereafter. Post-mortem examination showed acute fibrinous pleuropneumonia on days 9 and 16, and chronic pleuropneumonia on days 82 and 126, including sequester formations in goats killed on day 126. Mycoplasma capripneumoniae was isolated on days 9 and 16 but not on later occasions. The study showed that goats recovered from acute CCPP may have lesions for a long time thereafter but provide no evidence of a carrier state among long-term survivors.

Legionellosis is an important cause of severe pneumonia in the community. Inadequate therapy will lead to respiratory distress syndrome, disseminated intravascular coagulation (DIC) and finally fatal multiple organ failure. We encountered a rare case in which early manifestation included septic shock and DIC complicated by acute myocardial infarction (AMI) suspected to be derived from Legionnaires' disease. A 54-year-old healthy female complained of lumbago, high fever and dry cough 10 days after visiting a hot spring spa. She was emmergently admitted due to shock. Physical examination demonstrated hypotension, high fever, course creakle in the right lower lung. Hepatosplenomegaly, lymphadenopathy and eruption were not found. WBC count was 34600/microliters with nuclear shift. CRP elevated. FDP, D dimer and TAT also elevated CPK elevated with dominance of the MB isozyme. Chest roentogenography revealed congestive heart failure, pleural effusion and obscure pneumonic shadow and EKG showed ST segment elevation in leads I, II, III, aVF, V4, V5, and V6. The patient was diagnosed as having septic shock, DIC and AMI. She was treated with gabexate mesilate, high dose methyl prednisolone and dopamine hydrochloride as well as piperacillin, meropenem, isepamycin and fluconzaole. Despite intensive care, the blood pressure fell again and pneumonia had progressed on the 8th hospital day. These antibiotics appeared to be ineffective. Erythromycin was then administered and a dramatic effect. was obtained as the patient recovered. Serum titer of Legionella pneumophila (serogroup 1) rose to 128-fold 2 weeks after the onset. Other serum titers such as Chlamydia psittaci, Rickettsia, Mycoplasma were all negative. Cultures obtained from the sputum, throat swab, urine and blood did not yield any microorganisms. Although the diagnosis could not be confirmed because the titer did not elevate over 256-fold of 4-fold within 2 weeks after the onset, Legionella infection was highly suspected from the clinical features. This is a rare case in which septic shock and DIC with AMI preceded pulmonary symptoms in a non-immunocompromised patient.

The aim of this study was to compare the clinical, biological, and radiologic features of presentation in the emergency ward of community-acquired pneumonia (CAP) by Legionella pneumophila (LP) and other community-acquired bacterial pneumonias to help in early diagnosis of CAP by LP. Three hundred ninety-two patients with CAP were studied prospectively in the emergency department of a 600-bed university hospital. Univariate and multivariate analyses were performed to compare epidemiologic and demographic data and clinical, analytical, and radiologic features of presentation in 48 patients with CAP by LP and 125 patients with CAP by other bacterial etiology (68 by Streptococcus pneumoniae, 41 by Chlamydia pneumoniae, 5 by Mycoplasma pneumoniae, 4 by Coxiella burnetii, 3 by Pseudomonas aeruginosa, 2 by Haemophilus influenzae, and 2 by Nocardia species. Univariate analysis showed that CAP by LP was more frequent in middle-aged, male healthy (but alcohol drinking) patients than CAP by other etiology. Moreover, the lack of response to previous beta-lactamic drugs, headache, diarrhea, severe hyponatremia, and elevation in serum creatine kinase (CK) levels on presentation were more frequent in CAP by LP, while cough, expectoration, and thoracic pain were more frequent in CAP by other bacterial etiology. However, multivariate analysis only confirmed these differences with respect to lack of underlying disease, diarrhea, and elevation in the CK level. We conclude that detailed analysis of features of presentation of CAP allows suspicion of Legionnaire's disease in the emergency department. The initiation of antibiotic treatment, including a macrolide, and the performance of rapid diagnostic techniques are mandatory in these cases.

Previously, we reported the effectiveness of treatment with oxatomide (O), an antihistamine, plus dextromethorphan (D), and that of Bakumondo-to (B), an herbal drug that inhibits the activation of C-fibers, in patients with persistent coughing after upper-airway infection. In this study, we evaluated the efficacy and side effects of combination therapy (O + D + B) in patients with postinfectious persistent cough. Patients who had been coughing for more than three weeks and had a history of upper-airway infection took part in the study. None had any history of nasal disease, gastroesophageal reflux, bronchial asthma, or other chronic pulmonary disease. All patients were non-smokers, and none used angiotensin converting enzyme (ACE) inhibitors. All had normal chest roentgenograms and normal pulmonary function. The following hematological data were obtained before treatment: peripheral eosinophil counts. CRP levels, serum IgE concentrations, and titers of cold agglutinins and antibodies to Mycoplasma pneumoniae. The effects of one week of treatment with O + D + B on the severity of coughing, as estimated with a cough diary, were examined. Thirty-six patients entered the study, but only 18 with normal hematological findings who satisfied the study criteria were eligible for efficacy and side-effect analyses. Cough scores decreased significantly from 5.1 +/- 2.4 (range, 2-9) to 1.2 +/- 1.9 (range, 0-6), and the rate of cough disappearance was 50%. Two patients reported slight drowsiness. Therapy with O + D + B reduced perception of coughing as estimated with a cough diary. These results suggest that this therapy (O + D + B) may be useful in patients with postinfectious persistent cough.

A previously healthy 26-year-old woman presented with a fever and coughing on October 1, 1995. Despite treatment with beta-lactam antibiotics at another hospital, she had a high fever, coughing, and dyspnea. A chest roentgenogram showed diffuse infiltrates in both lung fields. On October 9, she was transferred to our hospital. On admission, a chest X-ray film showed marked diffusely infiltrates in both lung fields and a effusion in the left lung. Arterial blood gas analysis after inhalation of 4 liters per minute of oxygen via a nasal cannula revealed a PaO2 of 39.0 torr. Despite treatment with various antibiotics, including minocyclin and gamma-globulin, her respiratory condition rapidly deteriorated. She was mechanically ventilated by with intermittent mandatory ventilation and positive end-experiatory pressure, and received antibiotics and methylprednisolone pulse therapy. He chest X-ray and arterial blood gase findings, gradually improved. The passive hemagglutination titer for Mycoplasma rose from 1:4 on October 9, to 1:2,560 on the 14th hospital day. Acute respiratory failure due to Mycoplasma pneumoniae pneumonia was diagnosed. A chest X-ray film obtained 2 months after admission showed linear-reticular shadows in both lung fields and pulmonary-function tests revealed abnormally low vital capacity and diffusing capacity. Examination of a specimen obtained by transbronchial lung biopsy revealed focal intraalveolar exudate with fibrin and macrophages. Very mild interstitial thickening was also noted. The lymphocyte stimulation responses to PPD, PHA, and Con A were low early in the illness and became normal after recovery. Several reports have said that an enhanced pulmonary cellular immune response may be responsible for the development of severe Mycoplasma pneumoniae, resulting in a temporary decrease in the cell-mediated immune response. This case supports that hypothesis. We believe that in severe cases, steroid therapy including pulse therapy should be started as soon as possible.

A respiratory disease of lambs that has been termed the 'coughing syndrome' has been observed in the mid-western region of the United States of America. Mycoplasma ovipneumoniae (M. ovipneumoniae) and Mycoplasma arginini (M. arginini) were routinely isolated from the respiratory tract of lambs with this disease. A high level of antibodies reactive with ovine cilia of the upper respiratory tract was detected in the sera from many of the lambs in affected flocks but not in sera of lambs from unaffected flocks. The reactivity of these antibodies with cilia was demonstrated by ELISA and confirmed by indirect immunofluorescent staining and western immunoblotting. These antibodies were predominantly of the IgG isotype. They were distinct from cold or warm agglutinins and could be absorbed from the sera with cilia but not with antigens of common bacterial pathogens of the sheep respiratory tract including M. ovipneumoniae, M. arginini, Pasteurella haemolytica, Pasteurella multocida or Neisseria ovis. In addition, their occurrence appeared to be independent of the specific antibodies to M. ovipneumoniae and M. arginini. Western immunoblotting indicated that the antibodies were directed primarily against an antigen with apparent molecular weight of 50 kDa. In one flock from which serial serum samples were collected from the same lambs over a 10-month period, antibodies to ovine cilia developed before the onset of the clinical disease and persisted for a period of several months until most of the lambs had apparently recovered. However, colonization of the respiratory tract of the lambs by M. ovipneumoniae preceded the production of these antibodies. Sequential serum samples taken from another flock, with no known history of this coughing, showed no such antibodies throughout the sampling period. It is suggested that an immunopathologic mechanism involving production of autoantibodies directed against a ciliary antigen of the lambs could be a contributing factor to the pathogenesis of this clinical disease.

A fifty year-old female who had previously been well presented with a productive cough and a high fever. Her initial chest X-ray film showed no abnormal lung shadows. Despite partial improvement of the fever and the serum level of acute phase reactant (CRP) in response to intravenous administration of piperacillin, she complained of increasing severity of cough and dyspnea. Follow-up chest X-ray films taken five days after therapy with piperacillin showed diffuse nodular shadows in the mid-to-lower lung fields bilaterally. Chest CT scan disclosed diffuse miliary nodules at the lung periphery and thickening of bronchovascular markings. Chest auscultation revealed late inspiratory coarse crackles and expiratory wheezing, and the patient's arterial oxygen tension was 61 mmHg. Suspected of suffering from primary atypical pneumonia, she was started on therapy with intravenous minocyclin (200 mg/day), two days after treatment her symptoms began improving significantly. Anti-mycoplasma antibody was found to be x 1280, and cold hemoagglutinin x 1024, establishing the diagnosis of Mycoplasma pneumoniae infection. The patient's condition completely recovered following a one week treatment with minocyclin. We concluded that her respiratory infection was caused by piperacillin-sensitive mico-organism, and also Mycoplasma pneumoniae which brought about hypoxic acute bronchiolitis to the patient.

A prospective study was conducted over a 3-month winter period in three general practice clinics in an urban population in southern Israel to identify the etiological agents of respiratory tract infections (RTI) in adults. RTI was defined as an acute febrile illness with cough, coryza, sore throat or hoarseness. Serum samples were taken from all patients in both the acute and convalescent phases of their illness. Tests were conducted for detection of 17 microorganisms known to cause RTI, including serological tests for 16 known pathogens. An etiological diagnosis was established in 80 (66%) of the 122 patients who participated in the study. The distribution of the etiological agents was as follows: influenza B virus in 27 (22%) patients. Chlamydia pneumoniae in 22 (18%), Legionella spp. in 15 (12%), Mycoplasma pneumoniae in 13 (11%), influenza A virus in 11 (9%), Bordetella pertussis in 9 (7%), adenovirus in 4, Epstein Barr virus in 4, Haemophilus influenzae in 3, beta-hemolytic streptococci in 3, Streptococcus pneumoniae in 2, respiratory syncytial virus in 2, parainfluenza 1 virus in 2 and parainfluenza 2 virus in 1. No patients were found to be infected with Coxiella burnetii, Moraxella catarrhalis or parainfluenza 3 virus. More than one pathogen was identified in 27 (34%) patients in whom an etiological diagnosis was established. It is concluded that RTI is caused by a broad spectrum of etiological agents, a considerable number of patients having evidence of infection with more than one pathogen. The therapeutic significance of these findings should be elucidated in further studies.
