Is it useful to measure serum ferritin level in systemic lupus erythematosus patients?

Research Abstract

Background

Serum ferritin is elevated due to various conditions as inflammation and malignancy and could be up regulated in systemic lupus erythematosus (SLE).

Aim of work

To evaluate serum ferritin level in SLE patients and correlate it with different clinical and laboratory parameters as well as disease activity.

Patients and methods

The study was carried out on 46 SLE patients and 20 matched controls. SLE Disease Activity Index (SLEDAI) was assessed and patients subdivided into severe (SLEDAI ≥ 11) and mild to moderate (SLEDAI < 11) activity. Serum ferritin, iron and total iron binding capacity (TIBC) levels were assessed.

Results

They were 40 females and 6 males with a mean age of 36.7 ± 10.3 years and disease duration of 4.9 ± 2.3 years. Serum ferritin was significantly higher in patients than controls (163.5 ± 27.8 vs. 47.1 ± 10.6 ng/ml, p = 0.009). In patients, serum iron (49.2 ± 4.5 mg/dl) and TIBC (284.2 ± 80.8 mg/dl) were comparable with those in controls. Serum ferritin was significantly higher in patients with severe (220.9 ± 50.7 ng/ml) than those with mild-moderate activity (122.9 ± 29.7 ng/ml; p < 0.001). Serum ferritin was significantly higher in patients with anemia (p < 0.001) and thrombocytopenia (p = 0.03) and lower in those with leucopenia (p < 0.001) compared to those without. Ferritin significantly correlated only with hemoglobin (r = 0.5, p = 0.02), platelet count (r = 0.65, p = 0.03) and inversely with leucocytic count (r = −0.08, p = 0.006).

Conclusion

Serum ferritin is elevated significantly in SLE patients especially those with severe activity. A remarkable difference in serum ferritin levels in patients with hematological manifestations was found making it a potentially useful inflammatory marker for disease activity in patients with blood dyscrasia.

Detection of hearing loss in rheumatoid arthritis patients using extended high frequency audiometry: Is it related to disease activity and severity?

Research Abstract

Aim of the work

To evaluate audiological characteristics in rheumatoid arthritis (RA) patients compared with controls using extended high frequency audiometry and analyze their correlations with RA activity and severity to identify patients at higher risk of hearing loss.

Patients and methods

The study was carried out on 95 RA patients and 100 controls. Every subject underwent pure tone audiometry (PTA) from 250 through 8000 Hz, speech audiometry and extended high frequency audiometry (EHFA) from 10,000 to 20000 Hz. Disease activity score (DAS28) and RA medical records-based index of severity (RARBIS) were assessed.

Results

Patients were 85 females and 10 males with age mean 46.5 ± 1.1 years and disease duration of 9.57 ± 0.61 years. The hearing thresholds (HT) of patients were significantly higher than those of controls at all PTA (p < 0.001) and EHFA frequencies (p < 0.001). Hearing loss (HL) was detected in 68.4% and 64.2% by using PTA, while EHFA revealed it in 100% and 97.9% of right and left ears of RA patients respectively. Hearing loss was bilateral, symmetrical and sensorineural in all cases. HT of EHFA significantly correlated with age (r = 0.63, p < 0.001), age at onset (r = 0.51, p < 0.001), disease duration (r = 0.3, p = 0.03), DAS28 (r = 0.31, p = 0.01) and RARBIS (r = 0.21, p = 0.03).

Conclusion

Bilateral symmetrical sensorineural hearing loss (SNHL) is significantly more frequent in RA patients compared to control. EHFA is valuable test to detect HL in patients with RA. Older age, longer disease duration, higher disease activity and severity are important factors for the development of HL in RA.

Effect of Combined HCV Therapy on Natural Killer Cell Activity

Research Abstract

epatitis C virus (HCV) is a major health problem all over the world with the highest prevalence reported in Egypt. Various treatment regimens have been developed over the last years. Interferon (IFN) based regimen was the standard of care regimen and then the IFN-free therapies were emerged. Host innate immunity through the activity of natural killer (NK) cell is one of the major players in competing infections and tumors, by producing perforin and granzymes that cause cytolysis of target cells, or by the production of various cytokines such as natural interferon gamma. Natural cytotoxicity receptors (NCRs), including Nkp30, Nkp44 and Nkp46, are a group of activating receptors that almost have restricted expression on the surface of NK cells and their density correlates with NK cytotoxicity. The role of these cells is not fully elucidated in patients with chronic HCV infection either treatment-naive or treatment experienced. Therefore, this study aimed to investigate the change that occurs in NK cell activity and cytotoxicity in response to successful elimination of HCV from blood after triple therapy with PEG-IFN-α, ribavirin and sofosbuvir. A total of 56 (50 male: 6 female) HCV patients with mean age of 41.6±12.1 years were included in this study. They were divided into two groups: treatment naive group (20 patients) and the sustained virologic response (SVR) group (36 patients). All patients were investigated for their NK cell profile, NCRs, perforin and granzyme B expression by flow cytometry. Data was expressed as mean fluorescence intensity (MFI). Results revealed significant increase in MFI of granzyme B (P= 0.001) and decrease in MFI of
