Prospective pulmonary function tests (PFTs) of 49 long-term survivors of identical sibling bone marrow transplants (BMT) were analysed. Eight (16%) developed a persistent pulmonary syndrome characterised by a late onset, cough and dyspnoea, hyperinflation or patchy infiltrates on plain radiography and episodic bacterial infections. The predominant PFT pattern was obstructive (reduced forced expiratory ratio, FER) with a variable restrictive component (reduced vital capacity, VC). When compared with the other 41 patients (controls), mean FER (53% absolute) and VC (73% predicted) were significantly lower at 12 months (P = 0.005). Graft-versus-host disease (GVHD) was the only identifiable risk factor (odds ration 7.1). Five of 7 patients compared with 4 of 31 controls tested at 3 months had an abnormal FER or maximum mid-expiratory flow rate (MMFR), but not VC, prior to the onset of symptoms (P = 0.015). Patients with mild to moderate disease (FER 50-70%) had stable pulmonary function while severe cases progressed despite immunosuppressive agents. Earlier recognition of this syndrome by a reduced FER or MMFR may allow the initiation of therapy at a potentially reversible stage.

This study was performed in the Sereer region 150 km to the east of Dakar, the capital of Senegal. The population of the region is characterised by large seasonal migration, a high divorce rate (41% of marriages end in divorce) and frequent polygamy (1.8 married women per married man). We organised the medical centres in the region to monitor actively the epidemiology of HIV infection. Three populations were targeted: pregnant women presenting for their first prenatal consultation; patients presenting with STD; and people with chronic (more than three weeks) cough. The patients consulting for STD were recruited two ways: those presenting spontaneously and those identified during home interviews by the team performing a parallel sociological study of behaviour. Overall, the prevalence of HIV seropositivity was 0.2% of the women and 1.3% of the men (the difference is not significant). The seropositive individuals identified were 2 pregnant women and 5 patients (3 of 409 women and 2 of 84 men) with STD. There was no significant difference between the sex, age, marital status, or type of recruitment (spontaneous or identified by the sociological survey) of the HIV seropositive and seronegative individuals. The prevalence of treponema antibodies was 1.8% among pregnant women, 2% among STD patients and 2.4% among patients with chronic cough. There was no significant difference according to age, sex, marital status or motivation for consultation. More than half the patients consulting for STD presented biomedical disease. The majority of the STD patients were women: 70% of those spontaneous consulting; 90% of those identified by the survey; and 92% of those with biomedical disease were women.(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship between cystic fibrosis (CF) and sinus disease has been appreciated since at least 1959. Unfortunately the standard methods used to treat sinus disease have been very unrewarding in the CF patients. We evaluated the long-term results achieved on 17 patients with CF that underwent FES surgery between July 1988 and January 1991. This group consisted of 16 pediatric and 1 adult patients with previously diagnosed CF, documented chronic sinus disease and nasal polyposis that had failed long-term maximal medical management. The patients, or their parents, were contacted and asked to rate the severity and frequency of their symptoms associated with chronic sinus disease, pre- and postoperatively. The specific symptoms evaluated were nasal obstruction, nasal discharge, postnasal drip, halitosis and cough. In addition, we attempted to measure the number of hospitalizations and the presence and frequency of headaches. We were able to show that, while there was no change in the relative health of patients as measured by the number of hospitalizations, there was a significant improvement in the quality of life. There was a marked decline in the frequency of nasal obstruction, nasal discharge and postnasal drip and a high level of patient satisfaction with the procedure. No changes were seen in the frequency or nature of the cough, halitosis or headache.

The high incidence of serious chest infections in patients with Parkinson's disease is unexplained, but an impairment in cough reflex may have a role. Maximal voluntary cough (MVC) and reflex cough (RC) to inhalation of ultrasonically nebulized distilled water were analyzed in patients with Parkinson's disease and age-matched control subjects by monitoring the integrated electromyographic activity (IEMG) of abdominal muscles. The peak amplitude of IEMG activity (IEMGP) was expressed as a fraction of the highest IEMGP value observed during MVC corrected to account for possible losses in abdominal muscle force due to reduced central muscle activation. Cough intensity was indexed in terms of both the IEMGP and the ratio of IEMGP to the duration of the expiratory ramp (TEC), i.e., the rate of rise of IEMG activity. Cough threshold was slightly higher in patients than in control subjects, but the difference failed to reach statistical significance. Compared with control subjects, patients displayed a lower IEMGP during maximal expiratory pressure maneuvers (PEmax), MVC, and RC (p always < 0.01); TEC during RC was longer (p < 0.01) than in controls. Consequently, the rate of rise of IEMG activity during cough was always lower in patients (p < 0. 01), especially during RC. Finally, PEmax, and both the peak and rate of rise of IEMG activity during RC were inversely related to the level of clinical disability (Spearman rank correlation coefficient, rs = -0.88, -0.86, and -0.85, respectively, p always < 0.01). The results indicate that the central neural mechanisms subserving the recruitment of motor units and/or the increase in their frequency of discharge during voluntary and, even more markedly, RC are impaired in patients with Parkinson's disease.

The objectives of this study were to describe the clinical and radiological features at presentation, and the natural history of HIV-related bronchopulmonary Kaposi's sarcoma. A retrospective review of medical records and chest radiographs was performed in 106 HIV-infected homosexual men with bronchopulmonary Kaposi's sarcoma diagnosed at bronchoscopy between September 1988 and November 1994. The majority of patients had evidence of advanced HIV disease at diagnosis (median CD4 cell count was 15 x 10(6)/l, range 0-288), and 93% had had a diagnosis of cutaneous Kaposi's sarcoma for a median duration of 11 months prior to diagnosis of their bronchopulmonary disease. The most frequent symptoms at presentation were cough (92%), dyspnoea (69%), pleuritic pain (20%), haemoptysis (13%) and wheezing (10%). The most common radiological finding in 73% of our series was of poorly defined and confluent opacities, with predominant middle and lower zone involvement. Median survival was 4 months (range 0-37 months) from diagnosis and 9 months (range 1-25) from the onset of symptoms. Treatment with either chemotherapy or radiotherapy was associated with a significantly reduced risk of death (hazards ratio (HR)=0.48, 95% CI=0.26-0.87). Factors associated with a poor survival, after adjustment for treatment effect were older age (HR=1.79, 95% CI=1.22-2.84) for each 10-year increase in age; a history of pleuritic pain (HR=2.97, 95% CI=1.39-6.32); presence of pleural effusion on X-ray (HR=2.01, 95% CI=1.13-3.59) and a prior diagnosis of cutaneous Kaposi's sarcoma (HR=1.8, 95% CI=1.00, 3.24). Bronchopulmonary Kaposi's sarcoma occurs mainly in patients with advanced HIV disease and a prior history of cutaneous disease. Survival is poor, and adverse prognostic factors include older age at diagnosis and the presence of pleural disease.

Ablation of the larynx implies withdrawal of afferent information from receptors involved both in the control of expiratory flow and in the genesis of protective airway reflexes including coughing. To investigate the effects of laryngectomy on the sensory and motor component of coughing, maximal voluntary cough (MVC) efforts as well as the reflex cough (RC) responses at threshold (T) and suprathreshold (1.8 x T, ST) levels induced by inhalation of progressively increasing concentrations of ultrasonically nebulized distilled water (fog) were analyzed in 10 laryngectomized patients and 10 control subjects. Cough intensity was indexed in terms of both the peak amplitude of the integrated electromyographic activity of abdominal muscles (IEMGP) and the ratio of IEMGP to the duration of the expiratory ramp (TEC), i.e., the rate of rise of IEMG activity (IEMGP/TEC). Cough peak flow was also recorded. Cough threshold was similar in patients and controls, as were IEMGP, TEC, and IEMGP/ TEC recorded during MVC and RCST. In contrast, during RCT, patients' IEMGP was significantly reduced (p < 0.05), thus leading to a significant decrease in IEMGP/TEC (p < 0.05) even in the absence of significant differences in TEC. Cough flow closely correlated with IEMG-related variables. Cough volume acceleration, i. e., the ratio of cough peak flow to the corresponding time to cough peak flow was also significantly reduced in the patients, especially during RCT (p < 0.01). The results suggest that the lack of signals arising from the larynx may result in a reduction of cough volume acceleration as well as in the intensity of abdominal muscle contractions during RCT. These factors may contribute to facilitate the onset and/or the persistence of chest infections in laryngectomized patients.

Although influenza vaccination is recommended for individuals with HIV infection, there are no data indicating an increased incidence or severity of influenza in this population. We sought to describe the clinical manifestations and morbidity of influenza in HIV-infected patients. All cases of influenza occurring in HIV-infected individuals over 3 years at a large county hospital were reviewed. Forty-three cases of influenza were diagnosed. Most patients presented with typical signs and symptoms of influenza, including cough (90%), myalgias (64%), and fever (52%). Sore throat and headache occurred in less than half of patients. The mean CD4 cell count and HIV viral load in patients with influenza was 340 cells/mm(3) and 3.34 log copies/ml, respectively. No significant differences in CD4 counts or viral loads were noted in patients with pneumonia (n=7) compared with patients without pneumonia (n=36), P>0.5. Six patients were hospitalized. One patient each had encephalitis and renal failure, although the relationship to influenza was not clear. No new or unusual clinical manifestations were observed. The rate of pulmonary complications was similar to other studies in HIV-negative patients; however, the hospitalization rate was higher than commonly seen in HIV-negative individuals.

Differentiation between abacavir hypersensitivity and viral respiratory infections is problematic. Fifteen cases of abacavir hypersensitivity were matched to 30 controls with culture proven influenza A with no abacavir exposure. Rash was associated with hypersensitivity (odds ratio [OR] = 13.1, P = 0.02) as was the presence of nausea (OR = 30, P < 0.001), vomiting (OR = 17.1, P = 0.001) or diarrhoea (OR = 22, P < 0.001). The number of gastrointestinal symptoms was also predictive of hypersensitivity reaction (P < 0.001). Respiratory symptoms (cough, sore throat, or dyspnoea) were not associated with abacavir hypersensitivity (OR = 0.08, P = 0.001). Multivariate analysis confirmed the following associations for abacavir hypersensitivity: the number of gastrointestinal symptoms (OR = 8.6, P = 0.0032), cough (OR = 0.039, P = 0.02) and rash (OR = 16.9, P = 0.07). Abacavir hypersensitivity is strongly associated with gastrointestinal (GI) symptoms. Cough without GI symptoms is associated with influenza.

We present our experience with skeletal involvement of Pneumocystis jiroveci (ex P. carinii) infection in an HIV-seropositive patient. The objective of this study was to alert clinicians to the possibility that extrapulmonary P. jiroveci could affect the skeletal system in HIV-infected patients with extremely rapid progression. P. jiroveci infection of skeletal system has been rarely described elsewhere. A 51-year-old man complained of fever for six weeks, cough, anorexia, fatigue, and chest pain. He was found to be HIV seropositive. Repetitive (six samples) sputum and bronchoalveolar lavage fluid microbiologic tests were negative. High-resolution chest computed tomography (CT) scan revealed a small pulmonary mass. Abdominal CT scan revealed lesions in liver, spleen, kidneys, adrenal glands, lumbar vertebrae, and sacrum. Brain and skull CT scan was normal. A fine-needle biopsy of the lung mass was unrevealing. Cytological examination of sputum specimens showed findings consistent with non-small-cell lung carcinoma. Nineteen weeks post-presentation, the patient reported low-back pain. Within 24 hours after the onset of low-back pain, he developed focal neurological deficits, and a magnetic resonance imaging (MRI) of the skull and spine showed osteolytic lesions of the temporal bones bilaterally, multiple vertebral lesions, and lesions of sacrum and iliac bones. Radiotherapy of the lumbar spine and pelvis was given. Sternal aspiration was performed. Cytological examination revealed P. jiroveci. In conclusion, we describe a rare case of disseminated P. jiroveci infection in an HIV-seropositive patient, with multiple skeletal lesions, especially in the skull and in vertebrae region, and concomitant non-small-cell lung cancer, with a very poor prognosis.

A 55-year-old man, who had not suffered from any severe or recurrent bacterial infections previously, visited our hospital because of symptoms of fever, cough, sputum, and otorrhea. Chest X-ray and computed tomography demonstrated infiltrates in the right middle lobe and lingula. Pneumococcal pneumonia and tympanitis were diagnosed based on the isolation of Streptococcus pneumoniae from sputum and otorrhea specimens. A peripheral blood analysis showed a remarkable reduction in serum IgG level and the flow cytometric analysis of his peripheral monocytes indicated a significant reduction in Bruton's tyrosine kinase expression. Thus, we diagnosed his illness as X-linked agammaglobulinemia (XLA). Although immunoglobulin replacement therapy was performed, he developed recurrent lower respiratory tract infections. Low-dose long-term erythromycin treatment resulted in decreased frequency of respiratory tract infections. These results suggest that erythromycin therapy may be useful for the control of lower respiratory tract infections in patients with XLA. Even in adults with recurrent bacterial respiratory tract infections, the presence of XLA as an underlying disease should be considered. The effect of macrolide therapy for chronic lower respiratory tract infection associated with humoral immunodeficiency has rarely been reported. This case study may provide valuable information about macrolide therapy for such an infection in patients with humoral immunodeficiency.
