Invasive pulmonary aspergillosis is an opportunistic infection occurring in a background of severe immune depression. The majority of cases occur in patients who have malignant hematologic disease, particularly during chemotherapy induction or consolidations phases for acute non-lymphocytic leukemia. The principal risk factors are profound (PN < 500 per mm3) and prolonged (very high risk beyond 20 days) neutropenia, perturbed phagocyte function and cellular immune deficiency (AIDS, immunosuppressive treatment in organ and bone marrow recipients). Clinically, invasive pulmonary aspergillosis presents as acute non-specific pneumonia with cough, chest pain and fever. The severe infection rapidly becomes life-threatening. The development of massive hemoptysis is a major risk. We report four cases of invasive pulmonary aspergillosis in patients who had hemoptysis. All four patients developed non-specific pneumonia resistant to broad-spectrum antibiotics during post-chemotherapy aplasia. Computed tomography of the thorax and bronchoscopy with bronchoalveolar lavage was performed due to the occurrence of hemoptysis. In the first two cases, the patients were recovering from aplasia. The thoracic CT scan showed evidence of a cavitating mass with peripheral vessels. Bronchoscopy findings suggested mucosal lesions. The patients were managed surgically. Pathology confirmed the diagnosis of invasive pulmonary aspergillosis with the presence of ischemic necrosis of the pulmonary parenchyma harboring numerous aspergillus filaments. Outcome was favorable and chemotherapy was re-initiated in one case. These two patient died from their hematological disease a few months later. The other two patients remained in aplasia. A CT of the thorax showed multifocal infiltration with vascular contact. Bronchoscopy was again suggestive. One patient developed massive hemoptysis with respiratory distress. Embolization was performed but the patient died two days after onset of hemoptysis. In the last case, embolization was successful and outcome was favorable enabling a bone marrow allograft; the patient died a few months later from the hematological disease. The potential gravity of hemoptysis in the course of invasive pulmonary aspergillosis should lead to early treatment with emergency CT scan and, if possible, bronchoscopy with bronchoalveolar lavage to establish the therapeutic strategy based on surgical excision or embolization of the pulmonary or bronchial arteries.

An 8-year-old FIV-positive Australian cat was presented with coughing, periocular alopecia, pyrexia and inappetence. Skin scrapings demonstrated Demodex cati mites. Antibiotics were administered and it was treated successfully for periocular demodectic mange, but the cat continued to exhibit respiratory signs and lose weight. Further investigation revealed an ascarid infection and active chronic inflammation of undetected cause affecting the lower airways. Repetitive treatment with pyrantel failed to eradicate the ascarid infection. The cat became cachectic and developed moist ulcerative dermatitis of the neck, severe non-regenerative anaemia, leucopenia and thrombocytopenia. Necropsy and histopathology revealed mycobacteriosis affecting skin, lungs, spleen, lymph nodes, liver and kidney. Attempted culture of frozen tissues at a mycobacteria reference laboratory was unsuccessful. Paraffin-embedded, formalin-fixed tissue was retrieved and examined using PCR to amplify part of the 16S rRNA gene. A diagnosis of disseminated Mycobacterium genavense infection was made based on the presence of acid fast bacteria in many tissues and partial sequence of the 16S rRNA gene. Although M genavense has been identified previously as a cause of disseminated disease in AIDS patients, this is the first report of infection in a cat. It was suspected that the demodecosis, recurrent ascarid infections and disseminated M genavense infection resulted from an immune deficiency syndrome consequent to longstanding FIV infection.

Bronchiectasis is still common among some developing countries like Turkey. The aim of this study was to document the number of children with non-cystic fibrosis (CF) bronchiectasis, to evaluate the risk factors and to emphasize early diagnosis and treatment. All children, except those diagnosed with CF, with bronchiectasis established by chest radiogram, bronchography and/or computed tomography or biopsy material, were retrospectively reviewed. They were tested for serum total eosinophil count, nasal smear, serum levels of immunoglobulins A, G, M, E, and serum alpha-1 antitrypsin level. Pulmonary function tests, rigid bronchoscopy, nasal biopsy, lung scintigraphy, and echocardiogram were also performed. There were 204 patients whose most common presenting symptoms were cough, sputum expectoration, and dyspnea. Bronchiectasis was present mostly in the left lower lobe. The cause could not be determined in 49 per cent of patients. Among the identified causes, infection was present in most patients, followed by asthma, primary ciliary dyskinesia, congenital immune deficiency, and foreign body aspiration. It is possible to prevent bronchiectasis in children with vaccinations and improved nutrition in developing countries. Early diagnosis and treatment will increase the quality of life and survival of patients with bronchiectasis, which has irreversible and progressive complications if untreated.

Respiratory syncytial virus (RSV) is an important cause of lower respiratory tract infection (LRTI) in infants and children. There is growing evidence of severe RSV disease in infants with neuromuscular diseases and immune deficiency syndromes. Factors predisposing to a more severe course of RSV disease in neuromuscular diseases include the impaired ability to clear secretions from the airways due to ineffective cough, respiratory muscle weakness, high prevalence of gastro-oesophageal reflux and swallowing dysfunction which leads to aspiration. Similarly, pulmonary disease is a common presenting feature and complication of T-cell immunodeficiency. Infants with severe congenital and acquired immune deficiency syndromes may demonstrate prolonged viral shedding in RSV LRTI and are reported to have increased morbidity and mortality associated with RSV infection. Although not indicated in most guideline statements, palivizumab prophylaxis for these uncommon underlying conditions is under consideration by clinicians. Prospective studies are needed to determine the burden of RSV disease in these children.

The vaccine strain Mycobacterium bovis BCG may lead to disseminated infection in patients with immune deficiency. In this report a patient who developed fatal disseminated tuberculosis caused by M. bovis BCG strain was presented. One year old male patient with the previous history of recurrent lower respiratory tract infection, was admitted to the hospital with the complaints of fever, cough and diarrhea continuing for 20 days. There was no family history of tuberculosis or history of contact with a tuberculosis case. Physical examination of the case revealed growth retardation and reticular and reticulonodular infiltration was detected in his chest X-ray. The results of sweat test, cystic fibrosis gene mutation analysis and metabolic screening tests were normal. Since fever continued and infiltrations persisted in the chest X-ray despite antibiotic therapy, PPD test was applied and acid-fast bacilli (AFB) were investigated in his gastric aspirate and stool samples for three consecutive days. PPD test was negative and no AFB were detected in the microscopic examination of the clinical samples. However, growth in Lowenstein-Jensen medium was detected in the stool sample on the 38th day of incubation. The antimycobacterial susceptibility testing performed at BACTEC MGIT (Mycobacterial Growth Indicator Tube) 960 system (Becton-Dickinson, USA) revealed that the isolate was susceptible to rifampin, isoniazid, streptomicin and ethambutol. Since the isolates did not grow at PNB (para-nitro benzoic acid) medium and niacin and nitrate activities were negative, spoligotyping (spacer oligonucleotide typing) was performed and DR loci characteristic for M. bovis BCG strain were detected. However, the patient died 2 weeks before the culture results were obtained. The effective use of mycobacteriology laboratories and cooperation between laboratory and clinics provide advantages in the early diagnosis and treatment of tuberculosis cases, decreasing the morbidity and the mortality.

Described by Reich and Johnson in 1992 [2], the Lady Windermere syndrome occurs exclusively in non-smoking women over the age of 60 years, without significant pre-existing pulmonary disease. It comprises bronchial dilatation, typically in the middle lobe and lingula, together with secondary infection by atypical mycobacteria (Mycobacterium avium in the first cases). Among the 17 cases of atypical mycobacterial infection that we have seen in the past 14 years, there were seven cases of this syndrome. It was associated with cough, sputum, sometimes haemoptysis, febrile episodes and deterioration of general health. The diagnostic criteria and treatment were defined by the American Thoracic Society. The pathophysiological hypothesis proposed by Reich and Johnson was that voluntary suppression of the cough led to congestion of the bronchi and secondary infection with atypical mycobacteria. Currently it is thought more likely that the following factors are involved: progressive increase in dilatation of small bronchi, delayed diagnosis, morphological abnormalities of the thorax, hormonal factors, immune deficiency, genetic neutrophil dysfunction, and even heterozygous forms of cystic fibrosis.

A 15-year-old boy reported to the Accident and Emergency Department with excessive coughing, shortness of breath and pain in the area of his left shoulder blade. Methicillin-resistant Staphylococcus aureus (MRSA) was cultured from his sputum. The boy was otherwise healthy, and had no immune deficiency or underlying anatomic abnormality. He probably contracted the MRSA infection at the international school he attends.

Tuberculosis is the most frequent granulomatous disease involving larynx. In most cases it is secondary to pulmonary tuberculosis. Incidence of tuberculosis is now on a rise due to increase in incidence of immune deficiency states. Here we present a report of clinical characteristic of laryngeal tuberculosis based on our experience of 10 cases. A detailed retrospective analysis of 10 patients of laryngeal tuberculosis was done at our tertiary care laryngology centre. Majority of patients had change of voice and dry cough. All the patients had hyperemia and edema of vocal cords. 80% patients had involvement of the arytenoids and ary-epiglottic folds. Frank granulomatous growth was seen in 70% of patients. In all patients histopathological report was consistent with tubercular granuloma. Two patients had associated pulmonary tuberculosis. Eight patients did not reveal any feature suggestive of previous or co-existent pulmonary tuberculosis. All patients responded to chemotherapy with complete resolution. Primary laryngeal tuberculosis is not as rare as generally considered. This series provides an insight towards clinical feature, growth pattern and management of tuberculosis of larynx.

Ataxia-Telangiectasia (A-T) is a genetic condition leading to neurological defects and immune deficiency. The nature of the immune deficiency is highly variable, and in some cases causes significant morbidity and mortality due to recurrent sinopulmonary infections. Although the neurological defects in A-T are progressive, the natural history of the immune deficiency in A-T has not been evaluated formally. In this study we analyse the clinical history and immunological data in 44 patients with A-T who attended the National Ataxia-Telangiectasia clinic in Nottingham between 2001 and 2011. Using patient medical records and Nottingham University Hospitals (NUH) National Health Service Trust medical IT systems, data regarding clinical history, use of immunoglobulin replacement therapy, total immunoglobulin levels, specific antibody levels and lymphocyte subset counts were obtained. T cell receptor spectratyping results in some patients were already available and, where possible, repeat blood samples were collected for analysis. This study shows that subtle quantitative changes in certain immunological parameters such as lymphocyte subset counts may occur in patients with A-T over time. However, in general, for the majority of patients the severity of immune deficiency (both clinically and in terms of immunological blood markers) does not seem to deteriorate significantly with time. This finding serves to inform the long-term management of this cohort of patients because, if recurrent respiratory tract infections present later in life, then other contributory factors (e.g. cough/swallowing difficulties, underlying lung disease) should be investigated aggressively. Our findings also offer some form of reassurance for parents of children with A-T, which is otherwise a progressively severely debilitating condition.

We describe herein a 61-year-old woman who presented with fever, night sweats and cough. The diagnosis of pneumonia was established, but with symptom recurrence following antibiotic therapy, further diagnostics were performed. Biopsy via bronchoscopy revealed cryptogenic organizing pneumonia, and later on follow-up, a selective IgG immune deficiency was also diagnosed. Initial treatment of high-dose glucocorticoid therapy induced remission, but with dose reduction recurrence was observed. Intravenous immune globulin treatment was initiated and induced a successful clinical and radiological remission. Few cases of cryptogenic organizing pneumonia and hypogammaglobulinemia have been reported. To our knowledge, this is the fourth case described of cryptogenic organizing pneumonia with a hypogammaglobulinemia state and the first reported case of a selective immune deficiency state treated successfully with intravenous immune globulins.
