Familial Mediterranean fever (FMF), which is an autosomal recessive disease, is characterised by recurrent febrile episodes in association with peritonitis, pleuritis and arthritis and has ongoing subclinical inflammation during attack-free period. In this study, we aimed to investigate the relationship between FMF with neutrophil-to-lymphocyte ratio (NLR), which is determined in many chronic inflammations as a new potential inflammatory mediator. We included 62 patients and 41 healthy subjects who were similar in terms of age and sex. We found that the NLR values of the patients were significantly higher than those of the control group, and C-reactive protein values were correlated with NLR. Another finding was the NLR values were significantly higher in the FMF patient with M694V mutation than with other mutations. As a result, NLR might be used in the FMF patient as an indicator of the subclinical inflammation, and the FMF patients with M694V mutation should be followed up closely because of increased subclinical inflammation risk.
This is the first study investigating the relationship between NLR levels and ISSNHL and its prognosis. While evaluating ISSNHL, determining NLR should not be overlooked as a quick and reliable indicator for predicting the diagnosis and the prognosis of the disease.
Elaboration of clinical models of inflammation-induced atherogenesis may further advance our knowledge of multiple inflammatory pathways implicated in atherogenesis and provide a useful tool for cardiovascular prevention. We believe that the atherogenic index also be used as a preliminary indication of accelerated atherosclerosis in FMF. However, large-scale prospective studies on this issue are needed.
Diabetes mellitus (DM) is a systemic inflammatory disease. Sensorineural hearing loss (SNHL) is seen more frequently in diabetic patients and it is believed that vascular complications of DM may be the cause of SNHL via inflammation. Neutrophil-to-lymphocyte ratio (NLR) was defined as a novel-potential marker to determine inflammation. We aimed to investigate the relationship between NLR levels and SNHL in diabetic patients using high-frequency audiometry (8–16 kHz) for the first time. The study included 58 patients diagnosed with DM. The control group was composed of 45 age–sex–BMI–matched healthy subjects. An automated blood cell counter was used for NLR measurements. The hearing assessments of the patients were carried out by Interacoustics Clinical Audiometer AC 40 device. The mean NLR values of the patients were significantly higher than the control group (p = 0.015). Speech recognition threshold values were higher and the speech discrimination values were lower in patients (p = 0.002, p < 0.001), respectively. Pure tone average of the patients at 500, 1,000, 2,000 Hz frequencies was divided into two groups (group 1 >25 dB and group 2 <25 dB). NLR levels of the diabetic patients with >25 dB were higher than the other diabetics (p = 0.007). In conclusion, while diabetic patients are evaluating, audiologic assessments of these patients should be performed because they are at more risk of SNHL and NLR may be considered as a predictive and prognostic marker of hearing loss or its beginning in these patients as a useful and reliable marker without any cost.
Mean platelet volume (MPV) is one of the platelet function indices which reflects the platelet production rate and functions. While vascular occlusion, acute or chronic syndromes and vasculitis are increasing the MPV levels, infections, autoimmune diseases, and inflammatory situations reduce it. The indicator for idiopathic sudden sensorineural hearing loss (ISHL) etiology remains a matter of debate because it is associated with many different disorders. We evaluated MPV levels in ISHL patients. Forty patients with ISHL and 40 healthy, age and sex matched subjects were enrolled to the study. Audiometer and laboratory results were recorded. Comparative multivariate analyses between indicator factors and hearing outcomes were conducted. MPV and platelet distribution width is significantly higher in ISHL. Platelet count is lower in the ISHL than control group (p < 0.001), (p < 0.001), (p = 0.003), respectively. Our findings indicate that, ISHL appears to be characterized by ischaemic or thrombotic events. Considering the increased MPV levels; MPV may be used to evaluate ISHL as an hepler indicator.
