Epidermal growth factor receptor and proliferating cell nuclear antigen expression in urine ThinPrep specimens.

OBJECTIVE: To evaluate proliferating cell nuclear antigen (PCNA) and epidermal growth factor receptor (EGFR) expression in urine ThinPrep (TP) specimens, to compare these findings with clinical and histological features and to determine whether these immunomarkers are predictive of clinical stage. PATIENTS AND METHODS: The TP processed urine samples and the corresponding tissue sections from 42 patients with newly diagnosed bladder cancer (18 non-muscle invasive and 24 muscle invasive) were included in our study. Urine was collected for cytological evaluation before transurethral resection. Tumour grade and clinical stage were assessed from the transurethral resection specimens. The EGFR and PCNA expression was obtained by an automated immunostainer. RESULTS: There was a remarkable concordance in the expression of both antibodies in TP smears and tissue sections. No significant association was detected for any of the immunomarkers examined with regard to tumour grade. The EGFR expression as well as grade of malignancy were significantly associated with stage of disease (P = 0.0001). PCNA was not found to be a significant predictor of stage (P = 0.210). CONCLUSION: Our data suggest that the evaluation of grade of malignancy and EGFR immunopositivity can be considered as reliable predictors of disease stage in urine TP specimens.

Hearing loss in progressive systemic sclerosis patients: a comparative study.

OBJECTIVE: To investigate the middle and inner ear involvement in patients with progressive systemic sclerosis (PSS). STUDY DESIGN AND SETTINGS: We prospectively evaluated 34 PSS patients. All patients underwent a complete ear-nose-throat physical examination and audiological evaluation with pure tone, impedance, and speech audiometry. In addition, systemic manifestations of the disease and drug therapy were recorded. Finally, all patients were tested for the presence of autoantibodies. The results were compared with those of 45 age-matched healthy subjects. RESULTS: We found a sensorineural hearing loss in 20% and mixed type hearing loss in 3.3% of the patients. There was no correlation of hearing loss with age, systemic manifestations of the disease, presence of autoantibodies, and drug therapy. Ten percent of the patients had patulous eustachian tubes. CONCLUSION: One fourth of PSS patients had a hearing loss affecting the middle and mainly the high frequencies. This is a lower percentage than that reported by other investigators. A significant prevalence of bilateral patulous eustachian tubes was noticed as well. Further investigation is needed for a better understanding of the mechanism of ear damage in PSS patients.

Outcome of lupus pregnancy: a controlled study.

OBJECTIVE: The reciprocal relationship between systemic lupus erythematosus (SLE) and pregnancy was investigated in a controlled study. METHOD: The outcome of 47 pregnant SLE patients with 59 pregnancies was compared with that of 57 healthy control women and 59 pregnancies. The results were also compared with those of 59 non-pregnant control SLE patients. RESULTS: All pregnant SLE patients but one were in remission at the onset of pregnancy and were being treated with low doses of prednisone (< or = 10 mg/day, 26 patients), hydroxychloroquine (200 mg/day, eight patients) or azathioprine (100 mg/day, one patient). Sixty-one per cent of SLE pregnancies were delivered at term and 5% had premature deliveries. The rates of spontaneous abortion and total fetal loss were significantly higher in the mothers with SLE than in the control population (P: < 0.001 and P: < 0.01 respectively). None of the 39 neonates from SLE mothers had neonatal lupus, anti-Ro(SSA) or anti-La(SSB) antibodies. Eight out of 59 pregnancies of SLE mothers (13.5%) were characterized by disease exacerbation. Arthralgias or arthritis, fever and skin lesions were observed more frequently in the mothers with SLE than in the non-pregnant group (P: < 0.001). Renal involvement was found in three SLE patients during pregnancy and in three after delivery. CONCLUSIONS: Pregnant women with SLE are at high risk of fetal loss and spontaneous abortion. Pregnancy does not cause life-threatening manifestations of the disease. Thus, for a better outcome of lupus pregnancy, it is essential to control disease activity and to achieve clinical remission.

Subgroups of primary Sjögren's syndrome. Sjögren's syndrome in male and paediatric Greek patients.

OBJECTIVES: To describe the clinical and serological findings in male and paediatric Sjögren's syndrome (SS) patients. PATIENTS AND METHODS: Using the European criteria for the diagnosis of SS 12 male and 13 paediatric patients were identified and compared with those of 30 consecutive unselected adult female SS patients. RESULTS: The mean (SD) age of paediatric patients was 9.4 (2.2) years, ranging from 6 to 14 years. Recurrent parotid gland enlargement was the initial clinical manifestation in the majority of the children with a statistical significance compared with male (p < 0.01) and with female patients (p < 0.0001). Sicca manifestations were the most common clinical symptoms in male and female patients at disease onset. The systemic manifestations were similar among the three groups except that men showed lower frequency of arthritis (p < 0.05) and Raynaud's phenomenon (p < 0.05) compared with women. No differences were found among the immunological profile of children and female patients, while male patients had a lower frequency of antinuclear antibodies (p < 0.025) and antibodies to Ro(SSA) nuclear antigens (p < 0.025) compared with women. CONCLUSION: Primary SS is rare in children and men in Greece. Recurrent parotid gland enlargement is the most common clinical finding at disease onset in children. Male patients seem to have less systemic manifestations and lower frequency of autoantibodies.

Hearing loss in Sjögren's syndrome patients. A comparative study.

OBJECTIVE: In an attempt to investigate the presence of hearing loss in primary Sjögren's syndrome (SS) patients and to determine the factors that might be involved in its pathogenesis, we prospectively evaluated 45 female SS patients with a mean age of 56.8 +/- 9.23 years and a mean disease duration of 8.32 +/- 5.39 years. METHODS: Forty patients underwent a complete ear-nose-throat physical examination and audiological evaluation with: (a) pure tone audiometry thresholds at octave frequencies of 250 to 8000 Hz; (b) impedance audiometry (tympanogram, static compliance, acoustic reflexes, reflex decay; and (c) speech audiometry and auditory brainstem response where indicated. In addition, glandular and extraglandular manifestations of the disease and drug therapy were recorded. Finally, all patients were tested for the presence of autoantibodies, including: rheumatoid factor, antinuclear antibodies, antibodies to Ro(SSA), La(SSB) nuclear antigens, anticardiolipin antibodies and antineutrophil cytoplasmatic antibodies. The results were compared with those of 40 healthy, age-matched women. RESULTS: We found sensorineural hearing loss (SNHL) in 9 patients (22.5%): 4 patients bilaterally, 4 patients in the left ear only and one in the right ear only. In all cases the site of the ear damage was cochlear. A correlation between SNHL and the duration of the disease was found, while there was no correlation with age, systemic manifestations of the disease or the presence of autoantibodies. In addition, no correlation was found between SNHL and drug therapy. CONCLUSION: Approximately one-fourth of our SS patients presented SNHL of cochlear origin affecting mainly the high frequencies. This prevalence was lower than that reported by other investigators. SNHL was associated only with disease duration. Further investigation is needed to attain a better understanding of the mechanism of inner ear involvement in SS patients.

Cyclosporine A in the treatment of early rheumatoid arthritis. A prospective, randomized 24-month study.

OBJECTIVE: To investigate the efficacy, tolerability and safety of cyclosporine A (CSA) in early rheumatoid arthritis (RA) patients. METHODS: Patients with an early diagnosis of RA, a disease duration of less than 3 years, and without prior disease modifying antirheumatic drug (DMARD) treatment were studied. They randomly received oral CSA (3 mg/kg/day) or oral methotrexate (MTX) (0.15 mg/kg/week). In addition, all patients in both groups received oral prednisone (7.5 mg/day). RESULTS: Fifty-two patients were assigned to the CSA group and 51 to the MTX group. After 24 months of treatment, 48 patients from the CSA group and 48 from the MTX group showed significant clinical improvement. This was evaluated by the duration of morning stiffness, grip strength, the total joint count, joint swelling, and joint tenderness and pain, compared to pre-treatment values. The clinical improvement was also associated with a significant decrease in ESR and CRP values in both groups. No significant radiological deterioration was observed in the CSA patients compared to those treated with MTX after 24 months. Four patients from the CSA group dropped out of the study, two because of a synovitis flare, one because of severe hypertrichosis and one because of severe gingival hyperplasia. Three patients from the MTX group withdrew, one because of disease flare-up and two because of gastrointestinal disturbances. CONCLUSION: Early immunointervention in RA patients appears to be crucial to limit the development of joint damage. Cyclosporine A appears to be effective, well tolerated and safe in the long-term treatment of RA and can therefore be used as a first immunomodulatory drug in the armamentarium for the treatment of RA.
