There is increasing evidence that pertussis occurs frequently in adults, but there is limited information on the clinical course of this disease beyond childhood. A household contact study on the efficacy of an acellular pertussis vaccine was used to study the symptoms of pertussis in adults. Among 257 patients with pertussis identified in 121 families during a two-year period in one study center with a low whole-cell pertussis-vaccine uptake, 79 (30.7%) were adults, aged 19-83 years (mean age: 36 years) with a 1:1.8 male to female ratio. Ninety-one percent of the adults suffered from coughing (mean duration: 54 days), and in 80% this cough lasted > or = 21 days. Whoops were rare (8%), whereas cough followed by vomiting and/or choking (53%) and cough disturbing sleep (52%) were common. This is the first report to describe sweating attacks as symptom of pertussis (14%). Pharyngeal symptoms (37%), influenza-like symptoms (30%), sneezing attacks (22%), hoarseness (18%), sinus pain (16%) and headaches (14%) were also observed. Various complications were seen in 23% of the patients. In order to minimize the spread of the organism, microbiological diagnostics should be vigorously applied to all symptomatic contacts of a patient with pertussis but also to all patients with long lasting cough-irrespective of age.

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.

Pertussis in adolescents and adults is common, endemic, and epidemic worldwide, and its incidence is reportedly increasing. Although a number of individuals suffer only a mild cough, many others have symptoms typical of pertussis, causing prolonged cough illness, frequent use of health care resources, missed work and a variety of complications. Symptoms experienced by adolescents and adults include sleep disturbance, weight loss, pharyngeal discomfort, influenza-like symptoms, sneezing attacks, hoarseness, sinus pain, headaches and sweating attacks. Even when symptoms are typical of pertussis, the diagnosis is often not considered in adolescents and adults because of a low awareness of the disease in these age groups. Contrary to common perceptions, complications of pertussis, including some that are serious, are not infrequent in adolescents and adults. These include urinary incontinence, rib fracture, pneumothorax, inguinal hernia, aspiration, pneumonia, seizures and otitis media. Despite underreporting, hospitalization of adults and adolescents does occur. Many believe that adolescents and adults are the groups most commonly infected with pertussis and are now the major source of contagion to infants and young children. Because of the considerable health burden, there is a need for improved vaccination strategies to prevent disease in adolescents and adults and to reduce the risk of transmission to vulnerable infants.

Bordetella pertussis is a fastidious aerobic, Gram-negative coccobacillus that causes the classical disease of whooping cough. We present a 63 years old man with multiple myeloma who was admitted to the medical department with cough, hoarseness and fever. Bronchopneumonia was suspected and two courses of beta-lactam antibiotics had beneficial effect on his clinical condition, but his respiratory symptoms persisted. Eventually, B. pertussis grew in an aerobic blood culture. Delayed treatment with clarithromycin had little or no effect on his cough. To our knowledge this is the third reported case of B. pertussis bacteraemia. All three patients have been immunocompromized. Growth in blood culture may be slow, and prolonged incubation (at least 6 days) of the blood culture bottles and subculture to a special culture medium is necessary for isolation of B. pertussis.

Chlamydophila (Chlamydia) pneumoniae is a common, non-zoonotic cause of community-acquired pneumonia (CAP) in ambulatory young adults. C. pneumoniae clinically presents as a mycoplasma-like illness frequently accompanied by laryngitis. C. pneumoniae CAP may also cause nursing home outbreaks in the elderly. Similar to Mycoplasma pneumoniae in immunocompetent hosts, C. pneumoniae CAP usually manifests as a mild/moderately severe CAP. In contrast with Legionnaire's disease, central nervous system involvement is usually not a feature of C. pneumoniae CAP. M. pneumoniae may rarely present with meningoencephalitis accompanied by high cold agglutinin titers. We present the case of a young man who presented with M. pneumoniae-like illness and was hospitalized for severe CAP that was accompanied by a pertussis-like cough and severe headache. Although his chest x-ray showed a right upper lobe infiltrate, a lumbar puncture was performed to rule out meningitis, but his cerebrospinal fluid profile was unremarkable. Titers for non-zoonotic atypical pneumonia pathogens were negative except for a highly elevated C. pneumoniae immunoglobulin-M titer (1:320). Testing for legionella and pertussis was negative. Q fever and adenoviral titers were also negative. Cold agglutinin titers were repeatedly negative. The patient was successfully treated with moxifloxacin but developed permanent asthma after C. pneumoniae CAP. This case is unusual in several aspects. First, C. pneumoniae usually presents as a mild to moderate CAP, but in this case it was severe. Second, hoarseness was absent, which would have suggested C. pneumoniae. Third, wheezing was an important clue to the diagnosis of C. pneumoniae, which is not a clinical finding with other causes of CAP. Fourth, permanent asthma may follow C. pneumoniae, as well as M. pneumoniae CAP. Fifth, severe headache mimicking M. pneumoniae meningoencephalitis may rarely accompany C. pneumoniae CAP.

Pertussis is a rare condition in adults. This report describes a 65-year-old man presenting to the otolaryngology service with hoarseness secondary to pertussis. He had a history of worsening cough and hoarseness occurring over several weeks. Laryngoscopy showed significant erythema at the medial edges of the vocal folds. Stroboscopy demonstrated bilateral decreased amplitude and decreased mucosal wave of the vocal folds. Polymerase chain reaction testing of the sputum revealed Bordetella pertussis. The patient was started on azithromycin, and he reported gradual resolution of the chest and laryngeal symptoms over the next few months. Pertussis, or whooping cough, is not common in the United States because of childhood vaccination protocols. Nevertheless, otolaryngologists need to be aware of this condition as a possible cause of hoarseness.
