Otolaryngologic manifestations in HIV disease - clinical aspects and treatment

HIV is a pandemic infection with cases notified in almost all countries. The reported prevalence of symptoms in the head and neck is about 80%; otolaryngologists may be the first physician to see such patients. Oral manifestations are the most common, followed by neck and sinus manifestations. Otolaryngologic symptoms may be important signs of antiretroviral therapy failure. Symptoms are present in acute infections and advanced cases.ObjectiveTo describe new approaches in the past five years for the treatment of the most frequent otolaryngologic manifestations in HIV patients.MethodsSystematic reviews and case series published in English and Portuguese from January 2002 to October 2007 including the most common otolaryngology manifestations were selected.ConclusionOtolaryngologic manifestations are common and ENT specialists must be prepared to identify such cases.     

Pediatric human immunodeficiency virus infection: an otolaryngologist's perspective

Children with human immunodeficiency virus (HIV) frequently have recurrent otitis media, chronic rhinorrhea, parotitis, cough and other common pediatric otolaryngologic problems. As these complaints often occur before more unusual opportunistic infections or pulmonary conditions prompt a diagnosis of acquired immunodeficiency syndrome (AIDS), members of our specialty are liable to see HIV-positive children before infection with the virus has been recognized. Children with HIV infection are also likely to be referred to us after diagnosis, as is any immunosuppressed child with otolaryngologic infections. These children may require procedures such as bronchoscopy, sinus irrigations or tympanocentesis. The subject of this review is the natural history of pediatric HIV infection with special emphasis on otolaryngologic manifestations and recommendations for safe techniques of examination and treatment.     

Oral manifestations of human immunodeficiency virus infection

It is important that both physicians and dentists recognize the earliest signs of HIV infection in order that a timely diagnosis and patient referral can be made for counseling and treatment. Candidiasis, hairy leukoplakia, and Kaposi's sarcoma are the most common oral manifestations, but there are other important lesions as well. They include severe necrotizing periodontitis, bacterial and viral infections, lymphomas, and carcinomas. The various oral lesions seen in patients with the acquired immunodeficiency syndrome are reviewed and managements are discussed.     

Upper airway obstruction due to tonsillar lymphadenopathy in human immunodeficiency virus infection

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.     

HIV manifestations in otolaryngology

PURPOSE: AIDS is a fatal illness, which breaks down the body's immunity and leaves the victim vulnerable to life-threatening opportunistic infections, neurological disorders, or unusual malignancies. About 80% of patients with HIV infections present with otolaryngological symptoms. Often, the otolaryngologist is the primary physician who diagnoses the HIV infection. He should be aware and vigilant for its symptoms and unusual presentations. The aim of our study was to determine the incidence of otolaryngological manifestations, the clinical presentations, relevant diagnostic tools, management, and survival rates. MATERIALS AND METHODS: We studied 968 patients who were diagnosed to have HIV infection at Kasturba Medical College, Mangalore, India, from January 1996 to December 2004. The incidence of otolaryngological manifestations was noted. Patients with opportunistic infections were treated by specific and symptomatic measures. Of 968 patients studied, 419 were followed up for a 5-year period. RESULTS: In our study, otolaryngological findings were noted in 79% of individuals. Oropharyngeal findings, which were the commonest, were seen in 59%, followed by cervical lymphadenopathy in 42% of patients. Oral candidiasis was the commonest oropharyngeal finding, seen in 39% of patients. Among nasal complaints, rhinosinusitis was the commonest, found in 17% of patients. Otological manifestations were seen in 20%, of which chronic suppurative otitis media was the commonest, seen in 13% of patients. Routine investigations were found to suffice for diagnosis. Of 419 patients who were followed up, the 5-year survival rate was 73%. CONCLUSION: With the increase in the number of AIDS cases, it is important for otolaryngologists to be aware of otolaryngological manifestations. Early diagnosis and timely intervention along with appropriate antiretroviral therapy improve survival rates.     

Head and neck manifestations of non-Hodgkin's lymphoma in human immunodeficiency virus-infected patients

PURPOSE: Non-Hodgkin's lymphoma is the 2nd most common malignancy in human immunodeficiency virus (HIV)-infected patients. However, limited information regarding head and neck manifestations of non-Hodgkin's lymphoma is present in the literature. The aim of this article is to describe the head and neck manifestations of non-Hodgkin's lymphoma in HIV-infected patients and compare it with that seen in noninfected patients. PATIENTS AND METHODS: A case-control study was performed including 124 patients with non-Hodgkin's lymphoma presenting over a 5.5-year period to tertiary care center in a metropolitan location. RESULTS: Overall, the anatomic distribution of non-Hodgkin's lymphoma is not altered in the presence of HIV infection with the head and neck region (63%) most often involved overall. However, within the head and neck region, extralymphatic disease is significantly more common in HIV-infected patients (59%) than noninfected patients (33%; P = .001). Central nervous system (CNS) involvement accounts for 41% of head and neck non-Hodgkin's lymphoma in HIV-infected patients, in contrast to only 12% of noninfected patients. High-grade lymphoma (68%) are more common than intermediate (30%) or low-grade disease (2%) in the HIV-infected population, whereas low (24%) and intermediate (60%) grades are more common than high-grade lymphoma (16%) in noninfected patients (P < .001). The large cell immunoblastic type (48%) is the most common subtype in HIV-infected patients, whereas diffuse large-cell type (32%) was most common in HIV-negative patients (P < .05). Survival is significantly poor for HIV-infected patients (P < .05). The impact of HIV infection on survival remain significant even after controlling for the effects of confounding factors. CONCLUSIONS: Head and neck involvement with non-Hodgkin's lymphoma occurs in a significant number of HIV-infected patients. Our data show that the distribution and course of non-Hodgkin's lymphoma is unique in HIV-infected patients. A high level of suspicion for non-Hodgkin's lymphoma is required in all cases of head and neck lesions in patients with HIV infection to facilitate management.     

Immunocytochemical identification of HIV (p24) antigen in parotid lymphoid lesions

Antibodies to specific human immunodeficiency virus (HIV) polypeptides are important laboratory markers of HIV infection. We have used an antibody to the major structural gag protein p24 of HIV-1 virus to immunochemically localize this capsid antigen in lymphoid cells from seven of eight patients at risk for HIV infection and who presented with parotid lymphadenopathy and lymphoepithelial cysts of the parotid gland. A clinicopathological assessment of these two manifestations as they relate to HIV infection is also presented.     

Early ENT manifestations of HIV infection/AIDS. An analysis of 76 cases observed in Africa

OBJECTIVE: The aim of this work is to describe the ENT clinical manifestations by which HIV positive patients inaugurate their AIDS-illness and to classify these manifestations in respect to the biological state of the infection. MATERIAL AND METHOD: It was a multicenter, prospective study carried out in the ENT services of Yaounde (Cameroon), between the period of September 2000 and June 2002. Included in this study were HIV patients who started their AIDS with an ENT illness. The stage of evolution of the HIV infection was evaluated using the CD4 and CD8 T lymphocyte counts. This was carried out using the Flux cytometric technique of Fascount/Becton. RESULTS: We thereafter recruited 76 patients. The incidence rate of ENT early manifestations in HIV positive patients was 11.5%. Pharyngeal and oral candidosis represented the most observed manifestation (30.60%), followed by peripheral facial paralysis (11.13%) and rhino-sinusitis (10.58%). Parotid gland hypertrophy represented 8.23% of the affections. Persistant cervical lymphadenopathy was observed in 7.05% of cases. Kaposi sarcoma and cervical lymph node tuberculosis represented each 3.53% of cases of the sample. The correlation of lymphocytic count and initial ENT manifestations showed that these manifestations were observed in all the biological states of the HIV/AIDS infection. CONCLUSION: The above mentioned ENT manifestations in the patient should motivate the request of the HIV screening tests.     

Tuberculosis in the upper aerodigestive tract and human immunodeficiency virus coinfections

OBJECTIVE: To describe the clinical manifestations of tuberculosis in the upper aerodigestive tract. DESIGN: Retrospective chart analysis. SETTING: Srinagarind Hospital, Department of Otolaryngology, Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand. METHODS: A review of medical records of patients diagnosed with mycobacterial infection of the upper aerodigestive tract between January 1991 and December 2000. MAIN OUTCOME MEASURES: Presenting symptoms, clinical findings, pathologic findings, pulmonary involvement, and outcome of treatment. RESULTS: Forty-five patients presented with upper aerodigestive tract tuberculosis. The nasopharynx was involved in 23 patients, the larynx in 16, the tonsils in 6, and the soft palate in 1. One patient had tuberculous infections in both the nasopharynx and tonsils. The mean duration of symptoms before diagnosis was 2.1 months. The pathologic findings included caseous granuloma and/or positive acid-fast bacilli (AFB) in 39 cases and chronic granulomatous inflammation with negative AFB in 6 cases. Pulmonary tuberculosis was found in 19 of the 36 patients who underwent radiography. A positive serologic test for human immunodeficiency virus (HIV) infection was found in 4 of 26 patients. These 26 patients, who received a full course of treatment, responded well. CONCLUSION: The most common site of tuberculosis in the head and neck involved the cervical lymph nodes and nasopharynx. Upper aerodigestive tract tuberculosis is difficult to differentiate from carcinoma; thus, tissue biopsy is necessary for a definite diagnosis. Chest radiography and screening for HIV infection are recommended in all patients with upper aerodigestive tract tuberculosis.     

AIDS in otorhinolaryngological practice

The acquired immune deficiency syndrome (AIDS) presents a global problem of XX century medicine. The speed with which this pathology spreads is great and the number of AIDS patients is increasing in geometric progression. At present AIDS is a real threat to the health and life of millions of people. It is very difficult to clinically diagnose AIDS because it manifests in the form of various tumors and opportunistic infections, with lesions localized on the skin and mucosa or in the viscera (lungs, brain, esophagus, gastro-intestinal tract). The most typical AIDS manifestations are: preumocystosis, oropharyngeal and esophagal candidosis, herpes simplex, herpes zoster, Kaposi's sarcoma, "hairy" leukoplakia, extranodal non-Hodgkin's lymphoma, etc. In the case of HIV infection and AIDS many lesions are located in ENT. This means that ENT doctors are to be well aware of their clinical manifestations to be able to detect this pathology.     

ENT presentations in children with HIV infection

Illnesses of the ear, nose and throat (ENT) are common in children with human immunodeficiency virus (HIV) infection. We reviewed the case files of 107 HIV seropositive children in the paediatric HIV unit at St Mary's Hospital. The prevalence, age of onset and type of ENT disease were reviewed. We also determined sex distribution, maternal country of origin and mode of transmission of HIV. Fifty per cent of the HIV children had ENT illnesses. Fifty-five per cent of the children presented with their first ENT symptom before age 3 years with 98% of the children having ENT manifestations by age 9 years. The commonest ENT diseases were cervical lymphadenopathy (70%), otitis media (46%), oral candidiasis (35%) and adenotonsillar disease (31%). HIV transmission was vertical in 90%. Maternal country of origin was Africa in 70% and the UK in 13%. Compared with previous studies, the proportion of HIV children with ENT problems appears to have decreased. Although our figures report a similar ENT symptom profile, the age at onset of these symptoms has increased.     

Otorhinolaryngological manifestations in children with human immunodeficiency virus infection

The otorhinolaryngological manifestations (ENTM) in AIDS were first described in 1983. Continuing research confirmed that the ENTM reached up to 100% of the infected individuals. In the infant population, this percentage is also found, differing by presenting specific ENTM. The main objectives of this study were to define the most common ENTM in HIV children and to observe the difference, when compared to non-infected children. The HIV detection was also correlated with the appearance of the first ENTM. The observational, case-control research involved the study of 40 children over a period of 1 year. It was found that HIV children have a higher occurrence of ENTM, herpes simplex virus gingivostomatitis, cervical lymphadenopathy and parotid hypertrophy. On the other hand, the proportion of children who developed rhinosinusitis, acute otitis media (AOM) and oral candidiasis (OC) were not statistically different among the groups. However, 90% of the HIV children presented at least one ENTM, as opposed to 45% of the immunocompetent children. Differences in the occurrence of the ENTM were noticed, some more suggestive of the HIV infection. Furthermore, the majority of the infected children had their first ENTM diagnosed before the infection of HIV was established.     

Otolaryngologic manifestations of human immunodeficiency virus infection

The otolaryngologist is uniquely positioned to detect and pursue manifestations of HIV in the head and neck. The presentation of problems subsequent to HIV infection is quite varied, but close investigation will often reveal treatable problems.     

Nasopharyngeal lymphatic tissue in patients infected with human immunodeficiency virus. A prospective clinicopathologic study

A prospective clinicopathologic study of the nasopharyngeal lymphatic tissue, using a standardized approach, was carried out in 66 patients infected with human immunodeficiency virus (HIV) in Aviano, Italy. Two hundred eighteen patients without HIV infection served as a control group. A significantly higher percentage of nasopharyngeal lymphatic tissue hypertrophy was observed in HIV-infected patients compared with the control group, both clinically and pathologically. The finding of a higher incidence of nasopharyngeal lymphatic tissue hypertrophy during some stages of the disease, when cervical lymph nodes are enlarged, suggests that the extranodal nasopharyngeal district behaves in the same way as the lymph nodes. Nasopharyngeal lymphatic tissue hypertrophy should be placed at the forefront of the hitherto known head and neck manifestations of HIV infection. An ear, nose, and throat examination is mandatory for all patients with known or suspected HIV infection.     

Stomatological lesions seen in HIV virus infection. II. Histopathological and ultrastructural studies

Buccal lesions observed in the clinical setting of human immunodeficiency virus (HIV) infection constitute a diverse group of pathological entities. Several are related to the opportunistic infections observed in association with HIV infection. "Hairy leukoplakia" is a recently described benign lesion that is presumably related to infection by Epstein-Barr virus (E.B.V.). Kaposi's sarcoma is seen somewhat frequently in the oral cavity, especially involving the palate of HIV infected patients. We have observed this lesion 19 times in this location. The diagnosis is usually relatively straight-forward. Both vascular inflammatory and more typical sarcomatous morphology sub-types are present. The salivary glands may show an important lymphoplasmocytic infiltration which is unusual in that associated epithelial changes are not observed. The salivary glands seem to be a seat of the lymphocytic infiltration seen in other organs during the course of HIV infection. As for the changes encountered in the lymph nodes in HIV infection, they represent different stages in the evolution of a dynamic process, which progresses from hyperplasia to atrophy of the lymph nodes.     

Nasal nitric oxide is reduced in patients with HIV

The gas nitric oxide (NO) is present in high concentrations in human nasal airways. Since NO is known to inhibit the growth of bacteria and viruses, it has been suggested that airborne NO represents the first line of defence against pathogens in the upper airways. Low nasal NO levels have been reported previously in patients susceptible to upper airway infection. Since HIV-positive patients are at risk for respiratory tract infections, including sinusitis, we studied the levels of NO in the upper and lower airways of these patients. A cross-sectional study with age-matched HIV patients and controls was carried out. Nasal and orally exhaled NO were measured in 31 HIV patients and 26 controls using a well-established chemiluminescence method developed for measurements of gaseous NO in the airways. Nasal NO was 21%, lower (p < 0.05, Student's t-test) in HIV patients than in controls, whereas orally exhaled NO did not differ between the two groups. We conclude that nasal NO is reduced in patients with HIV infection. The reduction in nasal NO may contribute to the decreased resistance to airway infections in these patients.     

Otolaryngologic manifestations of immunodeficiency

Otolaryngologists are frequently consulted to manage infectious and noninfectious complications of immune deficiency. Although defects of host defense and recurrent or severe infections are the most obvious manifestations of immune deficiency, patients are often at increased risk for autoimmune and malignant disease as well. Knowledge of primary and acquired immune deficiencies will facilitate appropriate identification, treatment, and referral of patients with these defects. When immunodeficiency is known or suspected, it is particularly important to have a high index of suspicion for unusual or severe manifestations of infection, to have a low threshold for obtaining imaging to aid in diagnosis, and to treat infections for longer periods of time with higher doses of antibiotic. Surgery may be required for definitive treatment of infections that do not respond to medical therapy and for management of complications of infectious disease     

Laryngeal Tuberculosis in HIV-Infected Patients: A Difficult Diagnosis

Unrecognized laryngeal tuberculosis (TB) poses a significant hazard to otolaryngologists. However, the changing manifestations of TB in patients with human immunodeficiency virus (HIV) infection can make its diagnosis difficult. In our population of 146 patients with TB involving the head and neck, HIV infection was present in 70 cases (48%). The prevalence of laryngeal TB in this population was 5.5% (8 patients). Concomitant HIV infection was present in 2 (25%) of 8 patients with laryngeal TB. A delay in the diagnosis of laryngeal TB occurred in 100% of patients with HIV infection, compared with 17% of non-HIV-infected patients (P = .055). The cause of the delayed diagnosis was multifactorial, mainly the presence of multiple confounding variables and the carcinoma-like appearance of the laryngeal TB lesions in HIV-infected patients. To reduce risk for transmission of TB to health care providers, a high level of suspicion must be present for all patients with laryngeal lesions, especially those with HIV infection.

Nasal Nitric Oxide is Reduced in Patients with HIV

The gas nitric oxide (NO) is present in high concentrations in human nasal airways. Since NO is known to inhibit the growth of bacteria and viruses, it has been suggested that airborne NO represents the first line of defence against pathogens in the upper airways. Low nasal NO levels have been reported previously in patients susceptible to upper airway infection. Since HIV-positive patients are at risk for respiratory tract infections, including sinusitis, we studied the levels of NO in the upper and lower airways of these patients. A cross-sectional study with age-matched HIV patients and controls was carried out. Nasal and orally exhaled NO were measured in 31 HIV patients and 26 controls using a well-established chemiluminescence method developed for measurements of gaseous NO in the airways. Nasal NO was 21% lower (p&lt;0.05, Student's t-test) in HIV patients than in controls, whereas orally exhaled NO did not differ between the two groups. We conclude that nasal NO is reduced in patients with HIV infection. The reduction in nasal NO may contribute to the decreased resistance to airway infections in these patients.     

HIV-associated cervicodorsal lipodystrophy: etiology and management

OBJECTIVES: To familiarize the otolaryngologist with the evaluation and management of cervicodorsal manifestations of lipodystrophy in patients who have been treated with HIV protease inhibitor medications. In addition, to share the benefits obtainable with ultrasonic tumescent liposuction treatment. STUDY DESIGN: Retrospective chart review of patients presenting to the senior author with symptomatic hypertrophic cervicodorsal fat pad attributable to HIV infection and HIV protease inhibitor use. RESULTS: Eight patients presented for evaluation of hypertrophic cervicodorsal fat pads between January 1, 2002 and December 31, 2004. All patients had been on protease inhibitors in the past and had minimal resolution after discontinuing offending agent. Most common presenting problems include disfigurement, limited range of upper extremity and neck motion, neck and back discomfort, and difficulty with sleep including sleep-study-confirmed obstructive sleep apnea. Five of eight patients underwent ultrasonic tumescent liposuction. Three patients had satisfactory improvement of symptoms after the first surgery, whereas the other two required additional operative sessions. No complications of hematoma, seroma, infection, prolonged pain, or re-accumulation of fat pad were encountered. The primary obstacle in the three nonoperative patients was insurance denial on the basis of deemed lack of established necessity. CONCLUSIONS: Cervicodorsal lipodystrophy is a well-recognized outcome of prolonged HIV infection and side effect of certain HIV medications. Patients may present with both esthetic and functional issues related to the excess tissue. Although cessation of associated medications may halt further progression, this alone does resolve the symptoms. Ultrasonic tumescent liposuction is shown in this study to be a well-suited modality for reduction of this fibrous adipose tissue. Multiple sessions may be necessary to achieve satisfactory results because of the tenacity of the tissue. It is important for the otolaryngologist to be familiar with the head and neck issues relevant to this disorder and its treatment.
