The occurrence of sinusitis in HIV-infected patients with fever.

Sinusitis is commonly occurring in patients infected with Human Immunodeficiency Virus I (HIV), but the occurrence and etiology have not been established. The purpose of this study was prospectively to determine the occurrence, site and type of paranasal sinus abnormalities seen on MRI in HIV-infected patients with fever, to relate the abnormalities to clinical and immunological parameters, and to determine the microbiological agents found in the sinus aspirates. MRI was performed in 54 HIV-infected patients with 70 evaluable episodes of fever. Patients receiving antibiotics were excluded. Bactrim was permitted, when given as prophylaxis of Pneumocystis carinii pneumonia. If abnormalities were found on MRI, sinus aspiration was performed and the aspirate investigated. MRI abnormalities were found in 54.3% of the patients with a significantly higher occurrence of pathological changes in AIDS patients compared with HIV-infected without AIDS. In approximately 2/3 of the aspirates a probable, etiologic agent was found. However, 1/3 of these agents were atypical such as cytomegalovirus and mycobacteriae; in one patient Non-Hodgkin's lymphoma was found. The high occurrence of sinusitis in HIV-infected patients and the atypical findings in the sinus aspirates stress the importance of searching for sinusitis and the etiology to ensure the correct treatment.     

Microbial flora of nose and paranasal sinuses in chronic maxillary sinusitis

Nasal secretions, maxillary sinus aspirates and specimens of the maxillary sinus mucosa were collected in 44 patients aged between 25 and 60 affected by mono- or bilateral chronic maxillary sinusitis, in order to establish the best sampling technique for microbiological purposes, the most frequently involved bacteria and the physiopathological mechanism underlying chronic maxillary disease. The sinusal mucosa resulted to be the most reliable sample as it reduces contamination and microbial variability. Anaerobic bacteria were isolated in nasal swab (15.6%), in maxillary sinus aspirates (30.4%) and in maxillary sinus mucosa (36.4%) of maxillary sinusitis patients. In controls anaerobic bacteria were isolated only in one nasal swab (2.3%), while they could not be isolated in maxillary sinus aspirates and in maxillary sinus mucosa. The presence of anaerobic bacteria in chronic maxillary sinusitis patients and their absence in controls seem to confirm that anaerobic microorganisms represent the main pathogenetic agents of chronic maxillary sinusitis. The possible physiopathological mechanisms underlying chronic maxillary sinus disease are finally discussed.     

Oropharyngeal kaposi sarcoma in related persons negative for human immunodeficiency virus

OBJECTIVES: Kaposi sarcoma (KS) is a vascular tumor that can affect the mucosa of the upper aerodigestive tract. Although KS is the most common malignancy in patients with acquired immunodeficiency syndrome, it is rare in immunocompetent persons. We describe an unusual presentation of KS in 2 related individuals and describe our attempts to determine whether oropharyngeal KS is associated with human herpesvirus 8 (HHV-8). METHODS: All relevant clinical and surgical information, including information on tumor histopathologic and human immunodeficiency virus (HIV) serologic tests, was abstracted from the patient charts and electronic databases. HHV-8 immunohistochemistry was performed on paraffin-fixed specimens. RESULTS: Both patient 1 and patient 2 (the nephew of patient 1) were referred for workup of a tonsillar mass that was pathologically confirmed to be KS. In each case, HIV serologic testing was negative, and a screening immunologic workup, including a quantitative natural killer cell count, a B- and T-lymphocyte count, and immunoglobulin analysis, also yielded findings that were within normal limits. Immunohistochemistry performed on 1 pathological specimen showed positive staining for the presence of HHV-8, the etiologic agent of KS. CONCLUSIONS: The presence of oropharyngeal KS in 2 related HIV-negative individuals supports a role for genetic factors in susceptibility to KS, a common exposure to an infectious agent such as HHV-8, or both. Whereas most KS cases in industrialized countries are associated with immunodeficiency, clinical and laboratory data do not suggest that either of the patients described in this report are immunodeficient. Their susceptibility to KS may be secondary to a subtle inherited defect in host resistance to HHV-8, or another unknown factor.     

Value of Antral Puncture in the Intensive Care Patient With Fever of Unknown Origin

Objective To evaluate the use of maxillary sinus puncture as a routine diagnostic procedure to exclude or confirm purulent sinusitis in intensive care unit (ICU) patients presenting with fever or a septic state of unknown origin. Study Design Retrospective. Methods All patients admitted to the ICU at the University Hospital Ghent who required ENT examination to exclude acute sinusitis as possible cause of their otherwise inexplicable fever or septic state underwent maxillary sinus puncture via the inferior meatus. The results of clinical examination and the relation between the presence of foreign bodies (e.g., nasogastric tubes) and culture results from the middle meatus and sinuses were analyzed. Results One hundred five punctures were performed in 53 patients. Macroscopic purulent effusions were obtained from 25 and nonpurulent effusions from 19 sinuses. The presence of a nasogastric tube did not influence puncture results but significantly increased colonization of the middle meatus. Staphylococcus aureus and Gram‐negative agents were frequently cultured from sinus aspirates. Although purulent secretions often reveal no growth, most patients present with a multibacterial (40%) or monobacterial (28%) infection. Simple anterior rhinoscopy reduces the need for antral puncture. Only 8% of punctures in patients with a normal clinical examination were positive. Conclusions Antral puncture proves to be a simple, fast, safe, inexpensive, and effective procedure for immediate diagnosis of acute nosocomial sinusitis in ICU patients and is therefore recommended as first procedure in these patients, even when only minor clinical abnormalities are present.     

Parotid localized Castleman’s disease and HHV-8 infection: a case report

Castleman’s disease (CD) is an unusual massive proliferation of lymphoid tissue distinct in two clinical forms, localized and multicentric. The multicentric form has been related to human herpesvirus 8 (HHV-8), especially in HIV-infected patients, whereas the localized form of CD is still unrelated to viral pathogens. We report a case of a HIV-negative 16-year-old male referred to our hospital with a 12-month history of a painless swelling in his right parotid region. A parotidectomy was performed, and histological analysis evidenced a localized CD. The search for HHV-8 revealed an active virus infection. The patient was commenced on corticosteroid therapy and a follow-up was performed every 6 months. The patient was commenced on corticosteroid therapy and there has been no recurrence after 24 months. The authors report a case of localized parotid CD in a patient with evidence of an active HHV-8 infection. The results of this study does for the first time suggest an association between HHV-8 and localized CD in HIV-negative subjects.     

Microbiology of acute exacerbation chronic sinusitis in adults

The bacterial flora taken by sinus puncture from 115 patients with uni and bilateral acute exacerbation of chronic maxillary sinusitis was analyzed. Germ-free culture was obtained in 49 cases (40%) and in 69 cases (60%) bacteria were isolated from all sinus aspirates. Microbiological evaluation shows, that in majority of cases (90%) of acute exacerbation of chronic sinusitis there were pathogenic bacteria namely aerobic and anaerobic. The most frequent pathogens isolated from the aspirates were; Staphylococcus aureus, Haemophilus influenzae, Escherichia coli, Streptococcus pneumoniae, Staphylococcus hominis, Propionibacterium acnes i Candida albicans. The culture analysis proves that one or more pathogens can be the etiological factor. In the majority of cases (64%) the sinusitis is caused by monoculture.     

Detection of HHV-8 and HPV in laryngeal carcinoma

OBJECTIVE: In this study we aimed to investigate the presence of human herpesvirus 8 (HHV-8) and human papillomavirus (HPV) in laryngeal carcinoma. MATERIALS AND METHODS: Fifty patients operated on because of laryngeal carcinoma were included in the study. Forty-seven had squamous cell carcinoma (SCC) whereas three had verrucous carcinoma. Fresh tumoral tissues, or tumoral tissues obtained from archival paraffin-embedded blocks, were examined. HHV-8 DNA and HPV DNA were detected using polymerase chain reaction (PCR) and viral genotypes of HPV were determined via the hybrid capture method. The presence of HHV-8 DNA and HPV DNA were also investigated in normal appearing laryngeal tissue collected from 50 cadavers at autopsy. RESULTS: HPV DNA was detected in seven patients (7/50; 14%) (5 out of 47 patients with SCC (5/47; 10.6%) and two out of three patients with verrucous carcinoma). HHV-8 DNA was detected in five patients and they all had SCC (5/47; 10.6%). One case had both HHV-8 and HPV DNA. None of the control samples from cadavers harbored HHV-8 DNA, or HPV DNA. There was a statistically significant correlation between HHV-8 DNA and HPV DNA positivity and laryngeal SCC (Fisher exact test; p=0.023 for each). No statistically significant correlations were found between the presence of HHV-8 and/or HPV and age, gender, tumor stage, differentiation, the site of the tumor, smoking and alcohol use. CONCLUSIONS: The findings of the present study suggest that beside HPV, HHV-8 might have a role in laryngeal carcinogenesis. Further investigations are necessary to clarify the exact role of these viruses in laryngeal carcinoma.     

Bacteriologic findings in patients with chronic sinusitis

We studied the bacteriology of maxillary sinus aspirates obtained from patients diagnosed with chronic sinusitis. We recovered 659 strains from 510 aspirates; of these, 572 (86.8%) were aerobes and 87 (13.2%) were anaerobes. Aerobes only were recovered from 310 of the 510 specimens (60.8%) and anaerobes only from 31 (6.1%). Among the 572 aerobic bacteria, the most prevalent organisms were Streptococcus viridans (158 strains [27.6%]), Streptococcus pneumoniae (67 [11.7%]), Corynebacterium species (66 [11.5%]), Staphylococcus aureus (54 [9.4%]), Moraxella catarrhalis (38 [6.6%]), Hemophilus parainfluenzae (33 [5.8%]), and group C beta-hemolytic streptococci (26 [4.5%]). Among the 87 recovered anaerobes were species of Peptostreptococcus (32 strains [36.8%]), Prevotella (22 [25.3%]), Actinomyces (13 [14.9%]), Propionibacterium (11 [12.6%]), Fusobacterium (8 [9.2%]), and Veillonella (1 [1.1%]). Beta-lactamase production was detected in 115 of the 572 aerobic strains (20.1%) and in 10 of the 87 anaerobic strains (11.5%). We found that the prevalence and type of organisms we identified in chronic sinusitis did not differ substantially from those reported in previous studies. Our study is one of the more extensive reports on the type and prevalence of pathogens in chronic sinusitis that has been published to date.     

Conversion to Chronic Invasive Fungal Sinusitis From Allergic Fungal Sinusitis in Immunocompetence

A review of the treatment of allergic and invasive fungal sinusitis, as well as a presentation of the first recorded case of a conversion from allergic fungal sinusitis (AFS) to chronic granulomatous invasive sinusitis and the fourth case of invasive fungal sinusitis associated with Curvularia. This immunocompetent patient suffering from chronic AFS converted after repeated high‐dose steroid tapers and noncompliance. AFS may present atypically and should be suspected even in immunocompetent patients with sinus disease who report new onset pain and neurologic symptoms. Clinicians should consider the potential complications associated with repeated systemic steroid administration. Laryngoscope, 129:2447–2450, 2019     

Increased expression of IL-4, IL-5, IFN-gamma, IL-6, IL-8, and TGF-beta mRNAs in maxillary mucosa of patients with chronic sinusitis

This study aimed to investigate expression of various cytokine mRNAs, including IL-6, IL-8, TGF-beta, IL-4, IL-5, and IFN-gamma in maxillary sinus mucosa of patients with chronic sinusitis. Maxillary sinus mucosae of six patients with chronic sinusitis and turbinate mucosae of six healthy subjects were obtained. We performed RT-PCR and Southern blot to examine gene expression of the cytokines IL-6, IL-8, TGF-beta, IL-4, IL-5, and IFN-gamma in maxillary sinus mucosa and compared the results with cytokine gene expressions in normal turbinate mucosa. IL-6, IL-8, TGF-beta, IL-4, IL-5, and IFN-gamma mRNAs were expressed more frequently in maxillary sinus mucosa from patients with chronic sinusitis than in normal turbinate mucosa. All the maxillary sinus mucosa specimens revealed relatively higher mean density ratio for each cytokine investigated than did normal turbinate mucosa. IL-6, IL-8, TGF-beta, IL-4, IL-5, and IFN-gamma mRNAs were expressed simultaneously in maxillary sinus mucosa of chronic sinusitis. These cytokines may be responsible for recruitment of inflammatory cells and for mucosal thickening in chronic sinusitis, and thus chronicity of the disease.     

Acanthamoeba rhinosinusitis: characterization, diagnosis, and treatment

Nasal and paranasal sinus manifestations are among the most common presentations of the acquired immunodeficiency syndrome (AIDS). Several studies cite that as many as 70% of patients with this disease have symptoms referable to the head and neck, including a 30% prevalence of sinusitis. Although the bacteriology of sinusitis in this population is largely considered comparable to that of immunocompetent patients, several opportunistic pathogens have been identified, particularly when T-cell counts are low. This report identifies Acanthamoeba as a potentially fatal cause of rhinosinusitis in immunosuppressed patients. The pathogenesis, diagnosis, and treatment of this rare entity will be discussed and the literature reviewed.     

Contemporary issues in rhinosinusitis and HIV infection

The medical issues involving patients infected with HIV continue to evolve dramatically. As they live longer sustained on antiretroviral therapy, their prevalence of acute and chronic sinusitis has increased. The common infectious causes of rhinosinusitis found in the general population are often the culprits in HIV-infected patients. However, as their CD4 counts dip below 200 cells/mm, these patients become susceptible to more opportunistic infections and neoplasms. The diagnostic and therapeutic measures used should reflect the physician's suspicion for these usual causes. The otolaryngologist should manage these patients aggressively because sinusitis can have a significant impact on the patients' quality of life as well as survival. Selected patients with either recurrent or chronic sinusitis may benefit from endoscopic sinus surgery.     

The bacteriology of acute maxillary sinusitis

Sinus secretions obtained by antral aspiration from 347 patients with acute maxillary sinusitis were examined bacteriologically. Special attention was paid to the method by which anaerobic bacteria could be recovered. On the total, 485 sinus secretion samples were examined, of these 336 were aspirates, 149 yields of injection-aspirations. Aerobic bacteria were cultured from 263 aspirates and from 100 injection-aspiration samples. Only anaerobes were recovered from 6 sinuses. Bacterial culture was negative in 115 sinuses (24%). The most common pathogens isolated were Haemophilus influenzae (50.5%), Streptococcus pneumoniae (18.5%), Streptococcus pyogenes (5%) and Branhamella catarrhalis (1.5%). A true anaerobic infection was considered to be present in only 7 sinuses (1.5%) indicating that anaerobes are not a significant cause of acute maxillary sinusitis. According to this study the most common pathogen in acute maxillary sinusitis in young adults is H. influenzae. From this follows that in such patients aminopenicillins may be a more appropriate choice than conventional penicillin in the antimicrobial treatment of acute maxillary sinusitis.     

Role of cytomegalovirus, Epstein-Barr virus, and human herpes virus-8 in benign lymphoepithelial cysts of the parotid gland

OBJECTIVE: To provide background and evaluate the role of herpesviruses in benign lymphoepithelial cysts (BLC) of the parotid gland. STUDY DESIGN: Case series derived from review of pathology specimens. METHODS: Radiolabeled polymerase chain reaction (PCR) analysis was used to detect for the presence of cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpes virus 8 (HHV-8) DNA sequences in 14 paraffin embedded specimens and 1 freshly aspirated BLC specimen. Thirteen normal parotid tissue specimens obtained from paraffin embedded blocks were used as a control group. RESULTS: CMV was detected with nearly equal frequency between the two groups (23% of normal vs. 20% in BLC). HHV-8 was found in 13% of the BLC group and in none of the normal group (P =.4841). There was significant difference in EBV detection between the normal (0%) and the BLC (33%) groups (P =.0437). CONCLUSION: CMV and HHV-8 does not appear to be associated with BLCs. Although EBV is found more frequently in BLC than in normal parotid controls, further studies are needed to elucidate the role of this virus in BLC pathogenesis.     

Search for Herpesviruses in cerebrospinal fluid of facial palsy patients by PCR

CONCLUSIONS: Herpes simplex virus 1 (HSV-1) and varicella-zoster virus (VZV) DNA were not detected in the cerebrospinal fluid (CSF) of patients with acute idiopathic peripheral facial palsy (Bell's palsy). Our results indicate either the absence of these viruses or the presence of technical shortcomings. The role of human herpesvirus 6 (HHV-6) in this disorder and the significance of a positive HHV-6 DNA finding in the central nervous system need further investigation. OBJECTIVE: Our goal was to determine whether DNA of HSV-1, VZV, or HHV-6 can be found by polymerase chain reaction (PCR) in the CSF of peripheral facial palsy patients. MATERIALS AND METHODS: We used PCR to detect the presence of HSV-1, VZV, and HHV-6 DNA in CSF. This was a retrospective case control study with 33 peripheral facial palsy patients (34 CSF samples) in the study group (26 with Bell's palsy, 5 with simultaneously diagnosed herpesvirus infection, 1 with puerperal facial palsy, 1 with Melkersson-Rosenthal syndrome). The control group included 36 patients, most with diagnosed or suspected Borreliosis and facial palsy or sudden deafness. RESULTS: One patient with Bell's palsy had HHV-6 DNA in CSF. Neither HSV-1 nor VZV DNA was detected in patients or controls.     

Quantitative analysis of mucin and lectin in maxillary sinus fluids in patients with acute and chronic sinusitis

OBJECTIVES: Sinusitis is characterized by quantitative and qualitative changes in mucus biosynthesis that contribute to sinus disease. In general, patients with acute sinusitis complain of purulent rhinorrhea, whereas those with chronic sinusitis complain of mucoid or mucopurulent rhinorrhea Locally produced mucin largely contributes to the high viscoelasticity of mucus in sinusitis. In this study, the authors attempt to quantify the concentrations of mucin and lectin in the maxillary sinus fluids from these patients. STUDY DESIGN: To assess the concentrations of mucin and lectin in aspirates of 11 acutely and 11 chronically inflamed maxillary sinuses, the concentration of mucin was measured by enzyme-linked immunosorbent assay (ELISA) and that of lectin by sandwiched enzyme-linked lectin assay (ELLA). RESULTS: The concentrations of mucin and lectin that were measured using monoclonal antibodies (HCS 4, HCS 14, and HCS 18) and Ulex europaeus agglutinin-1 (UEA-1) in chronic sinusitis were higher than those in acute sinusitis. The concentration of total protein in chronic sinusitis was lower than that in acute sinusitis. Each mucin and lectin versus total protein ratio in chronic sinusitis was higher than that in acute sinusitis. CONCLUSIONS: These data suggest that hypersecretion in chronic sinusitis may result from locally increased mucin production. Comprehension of this mechanism may be a strategy to prevent the viscous cycle of paranasal sinus fluids in chronic sinusitis.

Sinusitis in immunocompromised patients. A multicenter study

This paper evaluates different aspects of sinusitis in patients with a decreased immunological system, such as its prevalence and clinical evolution, its peculiar bacteriology and the altered response to treatment, and the prognosis, especially in patients with AIDS. There seems to be an increased prevalence of sinusitis in these patients, with a relationship between their immunological status and the severity and aggressiveness of the sinusitis. Bacteriological studies reveal the pressure of more aggressive species, such as P. aeruginosa, and specific sinusitis are more frequent, which may explain why the treatment with common antibiotics often remains uneffective. The simultaneous therapy of concomitant infections leads to a higher resistance towards common drugs. A standard treatment is therefore needed. The results of three studies, retrospective and prospective, on HIV-infected patients reveal a high incidence of acute sinusitis with aggressive bacteria.     

Paranasal sinusitis associated with nasotracheal and orotracheal long-term intubation.

The impact of nasotracheal and orotracheal long-term intubation on the development of sinusitis paranasalis was investigated in a prospective study. Daily A-scan ultrasound examinations of the maxillary sinuses were performed on 44 intensive care unit patients (20 nasally, 24 orally intubated) who required prolonged intubation (greater than 24 hours). At the end of the investigation period 19 (95%) of 20 nasotracheally and 15 (63%) of 24 orotracheally intubated patients showed pathologic antral sinus findings. In nasally intubated patients the incidence of bilateral sinusitis was significantly higher and its onset sooner. Pathologic organisms were found in the sinus aspirates in seven of 13 nasotracheally intubated patients, but only in two of nine patients with an oral tube. Thus, the nasotracheal tube can be seen as an adding factor in the development of sinusitis paranasalis.     

Clinical and therapeutic aspects of sinusitis in children with bronchial asthma

Eighty children between 4 and 14 years of age suffering from bronchial asthma were investigated. Fifty-five of them showed clinical and radiological findings of sinusitis. Of these, 13 patients with purulent postnasal drip were treated with ampicillin, phenylephrine and triprolidine (therapy A) and for the other 42 ampicillin was replaced by beclomethasone (therapy B). Thirtyfour of 55 children showed improvement in sinus X-rays; 20 children had a considerable decrease in the severity of asthma and many symptoms cleared up after the therapy for sinusitis (P < 0.001). In conclusion, owing to the high prevalence of sinusitis in children with bronchial asthma, all asthmatic children should be investigated to check for a sinus disease.
