Clinical evaluation and kinetics in serum of cefoperazone (CPZ) in patients with lower respiratory tract infections have been conducted as a multicenter trial participated by 20 institutions in Kyushu area during a period of 8 months from October 1984 to May 1985. Mean serum CPZ levels up to 4 hours following the end of intravenous infusion of either 1 or 2 g CPZ remained higher than the MIC80 of CPZ against major causative organisms of lower respiratory tract infections such as H. influenzae, P. aeruginosa, K. pneumoniae, and S. pneumoniae. Serum half-lives of CPZ following intravenous infusion were prolonged in the elderly and in patients who showed moderate liver or kidney dysfunction, but did not exceed twofold of normal value. Clinical efficacy rates of CPZ were 82.9% (34/41) against pneumonia, 80% (4/5) against lung abscess, 88.9% (32/36) against acute exacerbation of chronic bronchitis, 66.7% (2/3) against panbronchiolitis, 100% (1/1) against acute bronchitis, and 85.7% (12/14), 64.3% (9/14) and 70.0% (7/10) against infections concurrent to chronic respiratory diseases, pulmonary emphysema and bronchiectasis, respectively. The overall efficacy rate was 81.5% (101/124). Bacteriological eradication rates against P. aeruginosa, H. influenzae and S. pneumoniae were 60% (6/10), 88.9% (8/9) and 100% (3/3), respectively. The overall eradication rate including polymicrobial infection was 67.5% (27/40). The clinical efficacy rate of CPZ in patients with underlying diseases such as lung cancer, pulmonary tuberculosis, and pneumoconiosis, etc. was not significantly different from the efficacy rate in patients without these underlying diseases. Of 20 patients who failed to respond to previous antibiotic treatments, 13 were effectively treated by CPZ. Adverse reactions occurred in 6.7% (11/164) of the patients, and consisted primarily of rash, fever, diarrhea and loose stool. Laboratory abnormalities were seen in 5 patients during the study. These included elevations of S-GOT and S-GPT, eosinophilia and neutropenia. CPZ is a very useful drug in the treatment of lower respiratory tract infections because of its excellent clinical efficacy and rare incidence of abnormal accumulations in sera following the recommended 2-4 g/day administration even in the elderly.

Cattle with Pasteurella bronchopneumonia usually have a fever, abnormal respiratory sounds in the cranioventral lung fields, consolidation, pleuritis and abscesses. Lungworms primarily affect 4- to 6-month-old calves, which become febrile and dyspneic, with moist rales. Diagnosis is by fecal examination using the Baermann technic. Proliferative pneumonia usually affects stabled adults, which develop severe dyspnea and tachypnea. Diagnosis is by the history, clinical signs and lung biopsy. Acute bovine pulmonary emphysema is caused by ingestion of large amounts of L-tryptophan in lush pasture. Affected cattle have severe, acute dyspnea, an expiratory grunt and froth around the muzzle. Diagnosis is by the history and clinical signs. Bronchiolitis obliterans narrows the airways of older animals to cause dyspnea. A positive response to corticosteroids aids diagnosis. Anaphylaxis occurs in cattle of all types and ages and is precipitated by various antigens in a type-I hypersensitivity reaction. Use of atropine aids diagnosis. Allergic or hypersensitivity pneumonia is caused by an allergy to insecticides, dead ascarid larvae or the mold, Micropolyspora faeni. Diagnosis is by a history of insect fogger use, finding M faeni in the forage, and typical histologic lesions in lung samples. Cattle with caudal vena caval thrombosis have dyspnea, a fever, froth around the muzzle, an expiratory groan and hypergammaglobulinemia. Malignant catarrhal fever is diagnosed by a history of previous exposure to sheep and finding swollen lymph nodes, fever, neutropenia and arteritis.

In a multicenter phase II study, 30 patients with unresectable, locally advanced or metastatic squamous cell or adenocarcinoma of the esophagus were treated with folinic acid 200 mg/m2/d, 5-FU 300 mg/m2/d, and cisplatin 20 mg/m2/d intravenously for 5 days every 4 weeks. Two of 13 patients with squamous cell carcinoma (SCC) had a complete response (CR), but one died of pneumonia after 9 months while still in CR, and the other still in CR after more than 5 years. Six other patients (3 SCC, 2 of 16 with adenocarcinoma, 1 mixed histology) had a partial response with a median duration of 9 months (range 5 to 57 + months) for an overall response rate of 27%. A further 6 patients (20%) had stable disease. Grade 4 neutropenia occurred in 6 patients (20%), with 5 requiring antibiotics for associated fever. Other grade 4 toxicities were nausea and vomiting (1), anemia (1), and thrombocytopenia (1); there were three early deaths (emphysema, cardiac arrest, pulmonary embolism). This combination appears to be an active, convenient regimen for advanced esophageal cancer, resulting in prolonged remission and survival in some patients.

Pneumocystis Carinii and Trichosporon beigelii are opportunistic infections in immunocompromised patients. We report a case of a young lady who underwent haemopoeitic stem cell transplantation for relapsed acute lymphoblastic leukemia. This 25 years old female developed fever, dry cough and rapidly progressive dyspnoea during post transplant neutropenia and was found to be suffering from Pneumocystis carinii pneumonia. She was successfully treated with Co-trimoxazole. The patient again presented with similar symptoms on day 55 post transplant. This time Trichosporon beigelii was isolated from bronchoalveolar lavage and she responded to prompt antifungal therapy. Other complications encountered during the subsequent course were extensive subcutaneous emphysema and spontaneous pneumothorax that required chest intubation and brief hospitalization. The patient is presently nine months post transplant and is asymptomatic.

A Phase I / II study of docetaxel (DOC) and cisplatin (CDDP) combination therapy was conducted. The respective recommended dose (RD) in a phase I study was DOC 60 mg/m(2) and CDDP 80 mg/m(2). We performed a multicenter phase II study to assess the antitumor activity and toxicity of this RD. Patients with recurrent or unresectable squamous cell carcinoma of the head and neck were eligible. For inclusion in this study, patients were required to be >or=20<70 years of age with a Performance Status of 0 to 2. Adequate bone marrow as well as adequate renal and liver function were required. We assessed 22 patients, 13 of whom were enrolled in the phase II study, and 9 patients in phase I were given the RD. Grade 3 or higher neutropenia occurred in 12 patients (55%). There was no episode of febrile neutropenia of more than 3 days or grade 4 neutropenia of more than 3 days receiving G-CSF. Nausea was the most frequent toxicity, but only one patient experienced vomiting of more than grade 3. Pneumonia (grade 3), thrombocytopenia (grade 4) and emphysema (grade 2) were observed. No one achieved a complete response (CR) and 5 achieved a partial response (PR), for an overall response rate of 22.7% (5/22). Stable disease (SD) was seen in 11 and progressive disease (PD) in 6. In 21 of 22 patients, a relapse occurred despite previous treatment. For this population, the response rate was 19.0% (4/21).

Aging is associated with a reduced capability of the immune system to adequately respond to pathogens and to prevent tumor formation. As a consequence of immunosenescence, older people have a higher risk to develop infections as well as cancer. In addition, cancer itself may expose old patients to infections, including opportunistic infections, i.e. Pseudomonas aeruginosa, Aspergillus fumigatus and Cytomegalovirus infection. Patients with hematologic malignancies have a higher risk than patients with solid tumors, because of more prolonged disease-related and treatment-related neutropenia and intensive immunosuppressive regimens. Co-existing medical conditions, e.g. chronic renal failure, diabetes mellitus, emphysema, which are quite common in the elderly, may also contribute to rising the infectious risk, as well as the use of long term vascular catheters, which is required in a large number of cancer patients to administrate chemotherapy. Neutropenic infections do not only represent a major cause of morbidity and mortality, but may be responsible for a reduction of the antineoplastic treatment dose and dose intensity, thus compromising the overall treatment effectiveness. The use of antibiotic prophylaxis to reduce neutropenia-related infectious complications in patients with cancer is still object to debate. Quinolones represent the most attractive option, since these drugs have a broad antimicrobial spectrum, systemic bactericidal activity, good tolerability and lack of myelosuppression. However, fluoroquinolone prophylaxis has already been associated with the emergence and spread of resistant bacteria and strictly precludes the subsequent use of fluoroquinolones for initial empirical therapy; in addition, fluoroquinolones should be administered with caution among elderly patients, especially those with more pronounced vascular or degenerative impairment of the central nervous system, cardiac disease or electrolyte disturbances.

Alpha-1 antitrypsin deficiency is an autosomal, codominant disorder caused by mutations of the SERPINA1 gene. This genetic disorder is mainly associated with development of pulmonary emphysema and/or chronic liver disease and cirrhosis. Here we report a very rare alpha-1 antitrypsin Null Q0cairo homozygous mutation characterized by a complete absence of alpha-1 antitrypsin in the plasma, in a non-consanguineous Moroccan family. This mutation has been previously described in heterozygosis in only three cases worldwide: an Italian/Egyptian family and two Italian families (Zorzetto et al., 2005). The main clinical features in two members of this Moroccan family were the severity and precocity of bronchiectasis, quickly spreading and seriously limiting respiratory function and physical activity by the second decade of age. Moreover, the index case presented with many episodes of pulmonary infections concomitant with severe neutropenia. The third member of the family presented with ankylosing spondyloarthritis and developed panniculitis later but had no respiratory symptoms. The presence of this alpha-1-antitrypsin Q0cairo homozygous mutation could explain the severity of clinical manifestations. Moreover, our observations highlight a great variability of clinical expression for the same mutation: early severe bronchiectasis, panniculitis, rheumatologic manifestations. This study further underlines the importance of genotyping by whole SERPINA1 gene sequencing in addition to serum alpha-1 antitrypsin determination, to enable detection of alpha-1 antitrypsin deficiency due to rare genotypes.
