Inflammatory sinonasal disease is a common problem in patients infected with the human immunodeficiency virus (HIV). Although some patients present with acute or chronic sinusitis, many describe persistent nasal congestion and thick, tenacious postnasal drainage, even in the absence of infection. The efficacy of guaifenesin as a mucolytic is poorly documented and support for its use in this setting is primarily anecdotal. This double-blind, placebo-controlled study assessed changes in nasal symptoms among 23 HIV-infected patients receiving either 3 weeks of guaifenesin (2400 mg daily) or placebo. The guaifenesin group reported less nasal congestion and thinner postnasal drainage compared to the placebo group and these differences were statistically significant (P < .05). Guaifenesin appears to be effective in managing HIV-infected patients with symptomatic rhinosinusitis and may be a useful adjunct for treating acute and chronic sinusitis in this population.

The clinical immunologist is playing an increasingly important role in the evaluation and management of sinus disease. Although most patients with sinus disease are not immunodeficient, a significant proportion of patients with chronic sinusitis unresponsive to medical and/or surgical therapy may have an immunodeficiency. Most immunodeficient patients for whom sinusitis is a major clinical problem tend to be those with humoral immunodeficiency diseases. The role of immunoglobulin replacement therapy is well established for patients with global immunoglobulin and antibody deficiencies (e.g., X-linked agammaglobulinemia and common variable immunodeficiency) and may be helpful in controlling refractory sinusitis in patients with more selective immunoglobulin deficiencies (e.g., IgG subclass deficiency and selective antibody deficiencies), but efficacy in these conditions remains to be established by controlled studies. Many immunodeficient patients have a history of repeated sinus surgery before the recognition of their immune defect. Even in immunodeficient patients treated with antibiotics and immunoglobulin replacement therapy, functional endoscopic sinus surgery is successful in only half of the patients.

The efficacy of endoscopic sinus surgery was evaluated in 11 patients with diverse types of primary immunodeficiency disease and symptoms of chronic sinusitis. The postoperative symptoms and ability to eliminate antibiotics were used as outcome parameters. In two patients, the follow-up time was too short to assess therapeutic effectiveness. Five of the remaining nine patients had total or significant resolution of symptoms. Patients with transient immunodeficiency had the best resolution of symptoms. Eight of the total 11 patients were treated with intravenous immunoglobulin preoperatively, and in five patients, the treatment was continued postoperatively. The ability to terminate gamma-globulin reflects not the success of the surgery, but the transient nature of some of the immunodeficiencies.

Cultures from 105 children with chronic sinusitis who had failed aggressive medical management were retrospectively studied. Patients with immunodeficiency and cystic fibrosis were excluded from the study. Because the most common sites of disease were the infundibula and anterior ethmoid sinuses, samples of mucosa removed from the anterior ethmoid bullae during endoscopic ethmoidectomy were routinely cultured for aerobic and anaerobic organisms. Fungal cultures were performed for 55 bullae. The principal organisms isolated were alpha-hemolytic Streptococcus, Staphylococcus aureus, Moraxella catarrhalis, Streptococcus pneumoniae, and Haemophilus influenzae non-type B. Only 12 anaerobic organisms and four fungi were isolated. Of the 204 bullae cultured, multiple organisms were found in 61 bullae and 40 showed no growth. Isolates of other less common organisms were also found. These data are analyzed on the basis of age and duration of symptoms, and antibiotic treatment is described.

Head and neck manifestations of human immunodeficiency virus (HIV) infection are common and include diffuse cervical lymphadenopathy, cutaneous and mucosal Kaposi's sarcoma, mucosal herpes simplex infection, upper aerodigestivetractcandidiasis, and parotidlymphadenopathy and cysts. Recurrent otitis media and chronic sinusitis have been noted in the pediatric HIV population. We describe a patient with HIV-associated tonsillar and adenoid lymphadenopathy and upper airway obstruction. Pathologic analysis of the tonsillar tissue revealed severe lymphofollicular hyperplasia similar to that of other lymphoid tissue in HIV infection. The importance of symptomatic treatment of the airway obstruction is stressed.

In about 10% of patients operated on a chronic sinusitis, an aspergilloma is found in the paranasal sinus. To detect possible underlying immunodeficiencies, patients with aspergilloma were subjected to an immunological screening programme. The data were compared with those of patients suffering from non-mycotic chronic sinusitis and healthy controls. Totale lymphocyte counts and immunological levels were normal in both groups of sinusitis. Leukocyte subset analyses by membrane fluorescence revealed a significant decrease of CD11+ cells, i.e. macrophages/monocytes and NK cells, in both types of sinusitis. Furthermore, a markedly enhanced frequency of CD25+-cells, i.e. IL 2-receptor bearing cells, was observed in patients with aspergilloma. Peripheral blood lymphocytes of both groups of patients showed a significant reduction in the proliferative response to both T and B-cell mitogens, the values for the mitogens ConA and PWM being significantly lower in aspergilloma patients than in those with non-mycotic sinusitis. This lack of lymphocyte stimulation in the aspergilloma group was also manifest in skin tests to recall antigens. These first data suggest an immunodeficiency in association with chronic sinusitis caused by Aspergillus fumigatus. Further studies are needed to clarify if this defect is cause or result of the mycotic infection.

The bacteriology of sinusitis in human immunodeficiency virus (HIV)-infected patients has been only sporadically reported. In this study, we report the results of cultures taken from 12 HIV patients with refractory chronic sinusitis who underwent surgery. Nine of the 12 patients had positive cultures with 16 isolates and 5 patients having multiple isolates. Five of the 12 patients grew out atypical or opportunistic infections not responsive to standard medical therapy, including 3 patients with cytomegalovirus, 1 with Aspergillus fumigatus, and 1 with Mycobacterium kansasii. These results suggest the need for aggressive medical care for HIV-infected patients with sinusitis and early intervention for tissue cultures in patients who do not respond to standard antibiotic regimens.

Diagnostic criteria for allergic fungal sinusitis have not been established, and clinical information consists primarily of isolated case reports. We proposed five diagnostic criteria for allergic fungal sinusitis including: (1) the demonstration of the characteristic eosinophil-rich allergic mucin visually or histopathologically, (2) a positive fungal stain or culture from the sinus at surgery, and (3) the absence of immunodeficiency or diabetes. With these criteria, seven patients in our metropolitan area with allergic fungal sinusitis were identified in a short period. Initial symptoms in our seven patients reflected those in 99 case reports in that two children were first seen with proptosis, one child and three adults with nasal congestion, and one adult with symptoms of chronic sinusitis. All had pansinusitis as shown on x-ray films. Six patients were atopic, five had nasal polyposis, and five had Curvularia species cultured from the sinuses. Infections with Bipolaris species, asthma, and chronic sinusitis were less common in our patients than in those previously reported. Recurrent symptoms and additional surgery sometimes resulted when the diagnosis was delayed by failure to obtain silver stains for fungus on surgical material sent for histopathologic review. Sinus tomography showed that the fungal material in the sinuses was of high density, which distinguished it from polyps or bacterial exudate. Bony compression, erosion, and rupture of the sinus walls were common. Results of IgE levels, precipitin determinations, and eosinophil counts were variable in both our patients and those in the literature. On the basis of our review, we believe that the simple diagnostic criteria proposed are appropriate for both research and clinical purposes.

A total of 83 children and teenagers underwent endoscopic nasal and sinus surgery. Six patients had surgery for choanal atresia (4) and adenoid hypertrophy (2) and will only be briefly mentioned. Seventy-seven children and teenagers underwent endoscopic sinus surgery for acute and chronic sinusitis, choanal polyposis, and nasal polyposis with a minimum 2-year follow-up. One hundred thirty-three ethmoidectomies, 37 sphenoidotomies, and 119 maxillary antrostomies were performed. Subjective evaluation of the sinus surgery patients indicated that 38% of patients were cured and 55% improved during an average of 3.5 years of follow-up. The number cured and number improved are lower and higher, respectively, than in other reports of results because of the longer follow-up and patient selection. In addition, objective data were obtained on 34 patients with a second- or third-look procedure 2 weeks to 2 months after surgery. These examinations found significant granulation tissue, and almost 50% of patients had at least one maxillary ostia closed. Long-term objective results, however, are not available to determine whether the ostia remained closed. Problems with healing in children's endoscopic sinus surgery are unpredictable compared those in adult surgery because postoperative debridement and examination are often difficult to perform, thus allowing tissue to heal without control. In this series, other factors such as the increased risks of cystic fibrosis, allergy, and immunodeficiency were also more prevalent and compromised healing.(ABSTRACT TRUNCATED AT 250 WORDS)

From 1974 to 1994, 504 isolates of Prevotella and Porphyromonas spp. were obtained from 435 (21%) of 2033 specimens from 418 children. They included 160 (32%) Pr. melaninogenica, 105 (21%) Pr. intermedia, 84 (17%) P. asaccharolytica, 58 (12%) Pr. orisbuccae, and 58 (12%) Pr. oralis. Most Prevotella and Porphyromonas spp. were isolated from abscesses (176), pulmonary infections (85), ear infections (82), wound infections (44), peritonitis (38), paronychia (15) and chronic sinusitis (14). Predisposing conditions were noted in 111 (27%) of the cases; these included previous surgery in 41 (10%), foreign body in 36 (9%), neurological deficiencies in 29 (7%), immunodeficiency in 21 (5%), steroid therapy in 12 (4%), diabetes in 8 (2%) and malignancy in 7 (2%). Prevotella and Porphyromonas spp. were the only isolates in 14 (3%) patients, and mixed infection was encountered in 404 (97%). The micro-organisms most commonly isolated with Prevotella and Porphyromonas spp. were anaerobic cocci (393 isolates), Fusobacterium spp. (108), Bacteroides spp. (B. fragilis group) (95), Escherichia coli (56) and other gram-negative anaerobic bacilli (52). Most Bacteroides spp. and E. coli were isolated from intra-abdominal infections and skin and soft tissue infections around the rectal area, whereas most Fusobacterium spp. were isolated from oropharyngeal, pulmonary and head and neck sites. beta-Lactamase production was detected in 191 (38%) Prevotella and Porphyromonas isolates from all body sites. All patients received antimicrobial therapy, and surgical drainage was performed in 173 (41%) cases. Four patients died from their infection. These data illustrate the spectrum and importance of Prevotella and Porphyromonas spp. in infections in children.
