Because of pyrexia of unknown origin, we cultured blood, urine, and cerebrospinal fluid samples, which were negative. deafness, and the hearing ability cannot be recovered, it is very important to consider AAV as the differencial diagnosis and start treatment as early as possible, if we see the patient with hearing loss.We describe the case of a patient presented with mixed conductive-sensorineural hearing loss with positive MPO-ANCA that illustrates the new aspects of ANCA-related vasculitis. Case Report In October, 2013, a previously healthy 77-year-old Japanese man presented with a 2-week history of daily fevers peaking at 38C, chills, hearing loss, anorexia, loss of motivation, and almost 10 kg of unintentional weight loss over 2 weeks. He had begun wearing a hearing aid three days before admission. He had no amazing medical history or prescriptions. On an exam, he was alert PF-06471553 and conscious. Jolt accentuation was bad, and he did not have a stiff neck. The finger-nose test result was slightly poor for both hands. He could not walk having a tandem gait. He had hearing impairment in both ears but showed no muscle mass weakness. The findings on additional examinations were normal. The complete blood count and white-cell differential count were normal, as were the blood levels of electrolytes and glucose. The results of checks of the renal and liver function were also normal. He had elevated C-reactive protein levels (16.3 mg/dL), but additional blood test results, including ferritin, KL-6, -D glucan, and tumor markers (CEA and CA 19-9) and serology for hepatitis B, hepatitis C, and HIV, were normal. Pure firmness audiometry showed combined conductive-sensorineural hearing loss: right, 63.6 dB (bone conduction: 36.3 dB), remaining, 80.0 dB (bone conduction: 52.5 dB) (Fig. 1, Remaining). The hypertrophy of the tympanum and exudates fluid in the middle ear were found by an otoscope. A biopsy of the middle ear was not performed. Ear computed tomography (CT) showed soft tissue in both middle ear cavities and the tympanum as well as mastoid cells (Fig. 2), indicating exudative otitis press. There was no damage or disconnection of ossicles. Because of pyrexia of unfamiliar source, we cultured blood, urine, and cerebrospinal fluid samples, which were negative. Mycobacterium ethnicities of sputum and gastric secretions and the QuantiFERON?-TB Platinum (Cellestis, Carnegie, Australia) test were also bad. No vegetations were found on endothoracic echocardiography. Blood KL-6, SP-A, and SP-D levels were within normal limits, and an X-ray exam showed that interstitial pneumonia was unlikely. There were no mass lesions observed on CT. Blood tests after admission showed a high myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) level (300 U/mL), so we suspected ANCA-related vasculitis. There was no hypertrophic pachymeningitis on contrast-enhanced magnetic resonance imaging (MRI) (Fig. 3) or vision lesions. Open in a separate window Number 1. Auditory capacity. At admission (on the remaining). Ideal: 63.6 dB (bone conduction: 36.3 dB), remaining: 80.0 dB (bone conduction: 52.5 dB). When discharged (on the right). PF-06471553 The auditory capacity improved to right 37.5 dB and remaining 47.5 dB. : ideal air flow conduction, ?: ideal bone conduction, : remaining air flow conduction, ?: PF-06471553 remaining bone conduction. Open in a separate window Number 2. Ear CT showing smooth tissue in both middle ear cavities and the tympanum as well as mastoid cells. Open in a separate window Number 3. Contrast-enhanced magnetic resonance imaging (MRI) of the head was normal. There was no evidence of hypertrophic pachymeningitis, new infarction, or mass lesions. An aneurysm of the right internal carotid artery was suspected (image not demonstrated), but no further testing, such as angiography or CT scans, was performed. Fourteen days after admission, we started prednisolone (PSL) at 40 mg/day time and observed designated clinical improvement, a decreased fever, and the disappearance of cough the next day. The finger-nose test result returned to normal, and he was able to walk having a tandem gait. The auditory capacity gradually improved, so we reduced the PSL dose to 20 mg/day time and added azathioprine ATF1 50 mg/day time. The auditory capacity improved to 37.5 dB (right) and 47.5 dB (remaining) (Fig. 1, Right). No conductive-sensorineural mismatch was found. We consequently diagnosed the patient with ANCA-related vasculitis with main issues of pyrexia and hearing loss. Discussion Diseases with sensorineural hearing loss include acute/chronic otitis press, cholesteatoma, meningitis, otitis interna (by viral illness, meningitis, or otitis press), Meniere’s disease, sudden sensorineural hearing loss, medicines, otosclerosis, acoustic neuroma, trauma and perilymph fistula. In this case, otoscopy showed bilateral thickening of the tympanic membrane and pooling of the exudate, suggestive of serous otitis press. However, because of his sustained fever and weight loss, we suspected a tumor.
