Aspergillosis of the nose and paranasal sinuses in neutropenic patients at an oncology center

Invasive Fungal Sinusitis following Liver or Bone Marrow Transplantation

Invasive fungal infection of the nose and paranasal sinuses occurs almost exclusively in immunocompromised patients and is increasingly recognized as a complication of organ transplantation. We performed a retrospective chart review of 955 bone marrow and 749 liver transplant patients to identify risk factors, presenting signs and symptoms, methods of diagnosis, and successful management strategies. We report on five cases following bone marrow transplantation and one case following liver transplantation. Neutropenia is the single most important risk factor in the development of and recovery from invasive fungal sinusitis. Early diagnosis, combined with antifungal agents, hematopoietic growth factors, and aggressive surgical debridement is the most effective means of management.

Impact of Surgical Treatment on Paranasal Fungal Infections in Bone Marrow Transplant Patients

Invasive fungal sinusitis can develop in immunosuppressed patients. A more complex problem is immunosuppressed patients who have undergone bone marrow transplantation. For a prolonged period, they are both neutropenic and thrombocytopenic. Survival in these patients is poor, and the role for extensive surgical intervention for sinus disease has to be weighed against the risk and the potential that this is a systemic disease. Between January 1983 and June 1993, 29 bone marrow transplant recipients with documented invasive fungal infections of the sinuses and paranasal tissues required surgical intervention. This represents 1.7% of the total 1692 bone marrow transplants performed. There were 22 allogeneic, 6 autologous, and 3 unrelated donor transplants, with two patients receiving two separate grafts. Underlying diseases included 24 hematologic malignancies and 5 other disorders, including 1 aplastic anemia and 1 solid tumor. The mortality rate from the initial fungal infection was 62%. Twenty-seven percent resolved the initial infections but subsequently died of other causes. All patients received medical management, such as amphotericin, rifampin, and colony-stimulating factors, in addition to surgical intervention. Surgical management ranged from minimally invasive procedures to extensive resections including medial maxillectomies. Sixty-one percent of the patients who died of the initial infection had undergone extensive surgical procedures versus 55% of those who resolved the infection. Recovery of neutrophil counts was required to clear the infection but did not necessarily predict a good outcome because 50% of those who died of the infection had experienced neutrophil recovery. White blood cell counts at the time of surgery were not significantly different between the two groups. Prognosis was poor when cranial and orbital involvement and/or bony erosion occurred.

BACKGROUND

[corrected] Aspergillosis of the paranasal sinuses is subdivided into noninvasive and invasive types, depending on invasion of the tissue. The invasive form often occurs in immunodeficient patients and can be divided further into granulomatous, chronic invasive, and acute fulminating forms.

CASE REPORT

We report the clinical course of an immunosuppressed 64-year-old male with invasive aspergillosis originating from the sphenoid sinus with infiltration of the orbit and intracranial extension into the cavernous sinus. The patient was referred to our hospital with loss of vision, ptosis, and ophthalmoplegia of 3-month duration. Additionally he suffered from diabetes mellitus II and kidney failure after kidney transplantation. After CT scanning, endonasal sinus debridement and decompression of the orbit were carried out immediately. Histology revealed invasive aspergillosis. Postoperatively, both systemic and local antimycotic therapy and antibiotic treatment were performed. According to recommendations of the Undersea and Hyperbaric Medicine Society, cerebral abscess is a certain indication of hyperbaric oxygenation. We decided to attempt therapy for that as well. The patient died 3 weeks after surgical intervention due to carotid dissection.

CONCLUSION

Invasive aspergillosis of the paranasal sinuses and the skull base of immunsuppressed patients is usually lethal because of intracranial complications. Therefore, fast diagnosis using CT and MRI and surgical and antimycotic therapy are necessary.

Invasive aspergillosis of the paranasal sinuses and the skull base

Invasive aspergillosis (IA) originating from the paranasal sinuses can cause an intracranial growth mainly along the skull base and larger vessels. This study reports our experience in the diagnosis and treatment of a series of patients with IA. A retrospective chart review of four patients with chronic invasive intracranial aspergillosis was performed. Clinical signs, physical examinations, radiographs, histological samples, and outcome were demonstrated. The patients demonstrated different symptoms like exophthalmus, ophthalmoplegia, loss of vision, and hypaesthesia of the ophthalmic and maxillary nerve. Computed tomography and MRI revealed extensive sino-orbital and skull base lesions. The patients were treated with aggressive endonasal debridement, intravenous antifungal agents and daily irrigations with antimycotic suspensions. Furthermore, we applied hyperbaric oxygenation. Two patients died from complications due to subarachnoidal hemorrhage and accompanied complications respectively. Despite the high mortality rate patients with an invasive aspergillosis can be effectively treated in some cases by an early and rigorous treatment schedule using all surgical and conservative therapeutic options.

Primary aspergillosis of the sphenoid sinus with pituitary invasion - a rare differential diagnosis of sellar lesions

Aspergillosis belongs to the group of mycotic diseases of paranasal sinuses. The invasive forms, and particularly the fulminant forms, are potentially fatal. Isolated aspergillosis of the sphenoid sinus or the clivus is a difficult diagnosis, since the often misleading clinical manifestations of this rare disease develop late. These patients become apparent by neurological signs such as cavernous sinus syndrome, pseudotumor of the pituitary or the orbit. Diagnosis is often made intra-operatively or on histological examination. We report a case of invasive aspergillosis uniquely involving the sellar area revealed by clinical features suggesting a pseudotumor of the pituitary. Although such lesions are almost always seen in immune suppressed subjects, in our case, the patient was immune competent and had no past history of sinusitis.The question of whether, and when to perform limited or extensive surgery remains an issue for discussion, owing to the rarity of this disease honed by lack of experience. It depends on several factors: the kind of disease, the immunity, the subtype of invasive fungal sinusitis and the degree of tissue invasion.

Case report. Mycotic arteritis due to Aspergillus fumigatus in a diabetic with retrobulbar aspergillosis and mycotic meningitis

A 74-year-old man with diabetes mellitus type II, retinopathy and polyneuropathy suffered from exophthalmus, ptosis and diplopia. Magnetic resonance imaging and computer tomography showed a space-occupying process in the right orbital apex. An extranasal ethmoidectomy accompanied by an orbitotomia revealed the presence of septated hyphae. Aspergillus fumigatus was grown from the tissue. After surgical removal of the fungal masses, therapy with amphotericin B (1 mg kg(-1) body weight) plus itraconazole (Sempera, 200 mg per day) over 6 weeks was initiated. Five months later the patient's condition deteriorated again, with vomiting, nausea and pain behind the right eye plus increasing exophthalmus. Antifungal therapy was started again with amphotericin B and 5-fluorocytosine. Neutropenia did not occur. The patient became somnolent and deteriorated, a meningitis was suggested. Aspergillus antigen (titre 1:2, Pastorex) was detected in liquor. Anti-Aspergillus antibodies were not detectable. Both the right eye and retrobulbar fungal masses were eradicated by means of an exenteratio bulbi et orbitae. However, renal insufficiency and an apallic syndrome developed and the patient died. At autopsy, a mycotic aneurysm of the arteria carotis interna dextra was detected. The mycotic vasculitis of this aneurysm had caused a rupture of the blood vessel followed by a massive subarachnoidal haemorrhage. In addition, severe mycotic sphenoidal sinusitis and aspergillosis of the right orbit were seen, which had led to a bifrontal meningitis.

Successful treatment of an invasive aspergillosis of the skull base and paranasal sinuses with liposomal amphotericin B and itraconazole

Invasive aspergillosis and fulminant aspergillosis are rarities with a high mortality. In the literature there is no patient surviving an extended invasive aspergillosis of the paranasal sinuses and skull base after failure of operative intervention and of postoperative amphotericin B therapy. We report a complete remission of an invasive, partially fulminant aspergillosis. After an incomplete removal of the mycotic mass, we started postoperative drug therapy with amphotericin B. Under this treatment, the mycosis progressed. Additionally, the patient developed severe side effects, so that the treatment was interrupted. At this moment, we started a combined antimycotic drug therapy with liposomal amphotericin B and itraconazole. Within 10 weeks, clinically and radiologically, there was complete remission. The patient died 63 weeks after this treatment, due to a fulminant bacterial pneumonia. Postmortem histologic examination showed no aspergillosis in the skull base, paranasal sinuses, or lung.

Aspergillosis of the maxillary sinus

A rare cse of aspergillosis of the maxillary sinus is reported. Surgical excision including the lining of the infected sinus is the preferred method of treatment. Antifungal therapy does not seem to affect the prognosis of this disease.

Orofacial manifestations of the systemic mycoses

Aspergillosis, cryptococcosis and zygomycosis (mucormycosis) are overall the most common systemic mycoses but histoplasmosis is particularly endemic in parts of central USA and other areas worldwide. Orofacial lesions caused by systemic mycoses have rarely been reported in the past though they have been recorded particularly in outdoor workers from geographic areas with a high prevalence of infection and occasionally in immunocompromised individuals. Increasing world-wide travel, and the dramatic increase in numbers of immunocompromised persons, especially those with human immunodeficiency virus (HIV) disease, have been responsible for an increase in reports and other studies of orofacial disease in systemic mycoses and new opportunists are now being recognized. Those in Oral Medicine and Pathology must now be aware of the possibility of a systemic mycosis as the cause of chronic oral ulceration, chronic maxillary sinus infection, or bizarre mouth lesions, especially in patients with HIV disease, lymphoproliferative disorders, or diabetes mellitus, or in those who have been in endemic areas. Diagnosis and management should be undertaken in consultation with a physician with appropriate expertise, as pulmonary and other systemic infection may well be present. This paper reviews the eight main systemic mycoses.

Functional endoscopic sinus surgery in the immunocompromised child

Fungal sinusitis in the immunocompromised child is an aggressive, invasive process that may result in a fatal outcome if not diagnosed early. As a result of increasing use of bone marrow transplantation and new cytotoxic chemotherapeutic agents resulting in severe agranulocytopenia, more patients have become susceptible to fungal sinus disease. Functional endoscopic sinus surgery has emerged recently as an important surgical modality in the treatment of sinus disease in adults and children. Use of this technique in immunosuppressed children has allowed early diagnosis of fungal sinonasal disease, resulting in earlier surgical intervention. The high-quality fiberoptic capability of nasal endoscopes allows very detailed visualization of the internal anatomy of the nose and detects early mucosal changes as a result of intranasal fungal disease. Our experience using functional endoscopic sinus surgery in immunocompromised children over an 18-month period is reviewed. Our philosophy for diagnosis and management of immunocompromised children with suspected fungal sinonasal disease is discussed.

The infectious and hematologic otolaryngic complications of myelosuppressive cancer chemotherapy

The otolaryngologist-head and neck surgeon is frequently consulted to evaluate patients before the administration of myelosuppressive cancer chemotherapy. Fifty consecutive patients treated at the University of Pennsylvania Oncology Center were studied before and during chemotherapy for adult leukemia or bone marrow transplantation. Otolaryngic history, physical examination, radiographic studies, and hematologic surveys were analyzed for the duration of therapy in an attempt to identify risk factors for infectious and hematologic otolaryngic complications. Two-thirds of the patient studied experienced untoward effects that required the further attention of an otolaryngologist-head and neck surgeon. The various complications and associated correlations with the study parameters before and during chemotherapy are discussed.

Aspergillosis of the nose and paranasal sinuses

Fulminant aspergillosis was diagnosed on nasal biopsy in a 49 year old man who had features of an aspergilloma. Further postmortem examination of this area was performed and the results were contrasted with the histological features of other Aspergillus infections. The nasal biopsy specimen and postmortem examination showed infiltrating Aspergillus hyphae with tissue necrosis and little inflammatory response. The hyphae were easily seen with routine stains. This contrasts with the findings in invasive aspergillosis where there is fibrosis and a granulomatous response to the Aspergillus hyphae. The hyphae are seen in giant cells using fungal stains. In the saprophytic infections aspergilloma and allergic Aspergillus sinusitis there is no tissue invasion or destruction. Aspergillus infections of the nose and paranasal sinuses often require biopsy for accurate diagnosis. As treatment varies pathologists need to be able to distinguish the different patterns of infection.

Aspergillus sinusitis in neutropenic patients with cancer: a review

Aspergillosis typically occurs in patients with reduced host defenses; such patients include renal and marrow recipients as well as patients with chemotherapy-induced myelosuppression. Pulmonary structures are most frequently involved; non-pulmonary involvement (including sinus) has not been frequently reported. In the present study, paranasal sinusitis occurred in 52 myelosuppressed cancer patients treated over 5 years at the UMCC with chemotherapy. Twenty-one patients had Aspergillus sinusitis; Aspergillus spp., including flavus and niger, were directly recovered from sinus in 19 of the 21 infections. Two other patients were considered clinically, although not microbiologically, documented. Multiple predisposing factors for Aspergillus sinusitis during the 60 days prior to infection diagnosis appear to exist; these include: 1) granulocyte count less than 500 mm3 (mean duration, 42 days versus 14 days for sinusitis of other etiology; P less than 0.001); 2) prolonged hospitalization (mean duration, 22 days versus 14 days for patients with non-fungal sinusitis; P less than 0.001); and 3) prolonged antibiotic therapy (mean duration, 22 days versus 9 days; P less than 0.001). The Aspergillus sinusitis resolved in 18 of 21 patients following treatment with amphotericin B; however, 11 of 18 patients had infection recurrence that always developed when tumor recurred and chemotherapy was reinstituted.

Invasive aspergillosis in a patient with aplastic anemia receiving amphotericin B

Invasive mycotic infections are becoming more commonplace in immune-compromised hosts. Aspergillus species is the most commonly encountered fungal genus in our environment causing paranasal sinus fungal infection. Aspergillus paranasal sinus infections in the healthy host are readily treated and controlled. In the immune-compromised host this common organism can rapidly become fatal even if recognized and treated appropriately. We present a case history of a patient who died from her disease despite radical surgery and antifungicidal therapy. Recent methods for early diagnosis will be reviewed. Only one other case has been reported in the literature of a patient developing fulminant aspergillosis sinusitis while receiving amphotericin B.
