Retinal toxicity related to hydroxychloroquine in patients with systemic lupus erythematosus and rheumatoid arthritis.

PURPOSE: To compare the retinal toxicity due to hydroxychloroquine (HCQ) use in patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) using multifocal electroretinography (mfERG), fundus autofluorescence (FAF) and optical coherence tomography (OCT). METHODS: Patients who were using HCQ due to SLE and RA, and healthy subjects evaluated in this study. Central foveal thickness (CFT), inner-outer segment (IS-OS) junction irregularity, retinal nerve fiber layer thickness, mfERG and FAF measurements were performed to evaluate retinal toxicity. RESULTS: Study included 35 eyes of 35 SLE patients, 40 eyes of 40 RA patients and 20 eyes of 20 healthy subjects. In SLE group, retinal abnormality was found in three eyes with mfERG, in one eye with FAF and in four eyes with OCT. In RA group, retinal abnormality was found in 10 eyes with mfERG, in five eyes with FAF and in nine eyes with OCT. A statistically significant difference was found with respect to mfERG between "eyes with abnormal responses and without abnormal responses" and "eyes with abnormal responses and controls" (p < 0.05). A statistically significant difference was found with respect to CFT between "eyes with IS-OS junction irregularities and without IS-OS junction irregularities" and "eyes with/without IS-OS junction irregularities and controls" (p < 0.05). CONCLUSIONS: The use of HCQ seems to cause retinal toxicity more often in RA patients compared to SLE patients. For the early detection of retinal changes, OCT and mfERG can be used as screening tools due to their higher sensitivity rates compared to other tests.

Efficacy of golimumab on recurrent uveitis in HLA-B27-positive ankylosing spondylitis.

To evaluate the efficacy of golimumab on severe and frequent recurrent anterior uveitis in patients with HLA-B27-positive ankylosing spondylitis. In this study, 15 eyes of 12 HLA-B27-positive AS patients with resistant anterior uveitis who received 50 mg of subcutaneous golimumab (Gol) per month due to frequent uveitis recurrences were analyzed retrospectively between May 2013 and October 2015. Assessment criteria were uveitis activity, the number of recurrence of uveitis, visual acuity, systemic corticosteroid, or other drug requirement for maintenance of remission of AU. Twelve patients (15 eyes) with HLA-B27-positive ankylosing spondylitis and anterior uveitis have been treated with golimumab 50 mg/month. Remission of uveitis was observed in 12 eyes out of 15. Malign hypertension developed in one subject after the second dose of golimumab therefore the treatment was stopped and this subject was excluded from the study. Median follow-up time was 11 months (interquartile range: 8-18). No uveitic reaction was seen except in the patient who stopped treatment. No topical or systemic steroid necessity was needed except in two cases with oral 4 mg systemic maintenance. Visual acuity was significantly increased (p = 0.002). Golimumab may be a new and effective choice for maintaining remission and the prevention of recurrences of severe, resistant anterior uveitis in patients with HLA-B27-positive ankylosing spondylitis.

Inverse relationship between neutrophil lymphocyte ratio (NLR) and bone mineral density (BMD) in elderly people.

Osteoporosis is, an age related disorder, influencing elderly people worldwide. The latest data suggests that inflammation plays a critical role in bone remodeling and in pathogenesis of osteoporosis. NLR is a simple, non-invasive and cost-effective marker of inflammation in various malignancies and inflammatory diseases. The objective of the present study was to compare NLR levels in osteopenic, osteoporotic and control subjects and to assess the correlation between NLR levels and BMD. A total of 1635 patients aged 65 years or more were included in this cross-sectional study. BMD was measured by dual-energy X-ray absorptiometry (DEXA) at the lumbar spine and femur. Complete blood count (CBC), biomarkers of inflammation (C-reactive protein (CRP), erythrocyte sedimentation rate (ESR)), glucose/lipid metabolism and established risk factors were determined. In osteoporosis group, NLR levels were found to be elevated as compared to osteopenic and control group (2.54±1.45, 2.37±1.00 and 2.18±0.85, respectively). At multivariate analysis NLR emerged as independent predictor of osteoporosis (OR=1.122; 95%=1.020-1.235, p=0.018) and there was a significant negative correlation between lumbar spine (L2-L4), femoral neck scores and NLR (r=0.348, p<0.001; r=0.264, p=0.004, respectively). Elderly people with osteoporosis have elevated NLR levels, suggesting that inflammation may play an important role in bone remodeling.

Phrenic neuropathy in diabetic and prediabetic patients without neuromuscular complaint.

Neuropathy, one of the major reasons of morbidity in diabetes mellitus (DM), is associated with prediabetic conditions as well as DM. The present study aims to compare phrenic and peripheral nerves in prediabetic, diabetic patients and healthy controls. A total of 37 diabetic, 40 prediabetic patients and 18 healthy controls were enrolled in the study. All subjects underwent conventional sensory and motor nerve conduction studies. Bilateral phrenic and peripheric nerve conduction studies were performed. In both right and left phrenic nerves, the amplitudes were lower in prediabetic and diabetic patients than control subjects, respectively (p: 0.005 and p: 0.001). Both of the phrenic nerve conductions were altered similarly. The results of our study demonstrate that phrenic nerves are affected like peripheric nerves in prediabetic and diabetic patients. We suggest reminding phrenic neuropathy in newly onset respiratory failure in diabetic and prediabetic patients.

The association between homocysteine (hcy) and serum natural antioxidants in elderly bone mineral densitometry (BMD).

Previous studies showed oxidative stress had an important impact on osteoclastic and osteoblastic functions. Oxidative stress or low levels of antioxidants are supposed to reduce BMD and cause osteoporosis. hcy, gamma glutamyltransferase (GGT), uric acid, albumin and total bilirubin are simple laboratory parameters that are related with oxidative stress. In this study we compare the serum hcy and antioxidant levels in patients with osteoporosis, osteopenia and control subjects. A total of 2190 elderly persons (1348 patients with osteoporosis, 643 patients with osteopenia and 199 control subjects) who were referred to the outpatient clinic of the Department of Internal Medicine, Division of Geriatric Medicine at Hacettepe University Hospital for comprehensive geriatric assessment were included in this cross-sectional study. Mean age of subjects were 72.30 ± 6.34 in osteoporosis group, 71.92 ± 6.90 in osteopenia and 71.86 ± 5.88 in control group (p: 0.260). Multivariate regression analysis revealed that hypertension (HT) (OR: 0.675, 95% CI: 0.534-0.854, p: 0.001), diabetes mellitus (DM) (OR: 1.669, 95% CI: 1.301-2.142, p: <0.001), age (OR: 1.025, 95% CI: 1.006-1.044, p: 0.009), male gender (OR: 0.451, 95% CI: 0.358-0.569, p<0.001), uric acid (OR: 0.893, 95% CI: 0.837-0.952, p: 0.001), hcy (OR: 1.042, 95% CI: 1.023-1.061, p<0.001), albumin (OR: 0.521, 95% CI: 0.376-0.724, p<0.001), GGT (OR: 1.010, 95% CI: 1.003-1.017, p: 0.003), creatinine (OR: 0.630, 95% CI: 0.459-0.864, p: 0.004) were independent variables predicting the occurrence of osteoporosis. This study shows there is an imbalance between natural antioxidative and oxidative markers in patients with osteoporosis. Higher serum uric acid and albumin levels are associated with a lower prevalence of osteoporosis whereas higher hcy and GGT levels are associated lower BMD and higher osteoporosis prevalence.

Coexistence of osteoporosis (OP) and coronary artery disease (CAD) in the elderly: it is not just a by chance event.

Cardiovascular disease (CVD) and OP are common age-related conditions. In both cross-sectional and longitudinal epidemiologic studies, low bone mass has been related to increased frequency of CVD. But available data in geriatric population is limited. In this study we aimed to seek the possible relationship between CAD and low bone mineral density (BMD) in a large number of geriatric patients. A total of 2235 patients aged 65 years or more were included in this cross-sectional study. All patients underwent a complete geriatric assessment and evaluated for CAD and cardiovascular risk factors. BMD was measured by dual-energy X-ray absorptiometry at the lumbar spine (L1-L4) and femoral neck. BMD results were classified into three groups; normal (T-score: ≥-1.0×S.D.), osteopenia (T-score between -1.0 and -2.5×S.D.), and OP (T-score: ≤-2.5×S.D.). CAD was present in 397 (29.7%) of 1335 patients with OP, in 199 (27.4%) of 726 patients with osteopenia and in 34 (19.5%) of 174 patients with normal BMD. Multivariate regression analysis revealed that presence of OP or osteopenia increased the prevalence of CAD as an independent correlate (OR=1.643; 95% CI=1.068-2.528, p=0.030). This study highlights the need for careful evaluation of elderly patients with low BMD for possible CAD.

Patients with iron deficiency anemia have an increased prevalence of gallstones.

We determined the frequency of gallstones (GS) in iron deficiency anemia (IDA) patients and evaluated factors that could affect GS formation-like lipid levels and gallbladder (GB) motilities of the patients. One hundred and eleven IDA patients (88 females, 23 males; median age, 42) and 81 healthy controls (68 females, 13 males; median age, 42) were included into our study. The clinical findings of all IDA patients were recorded down; biochemical values and body mass index (BMI) were determined; and abdominal ultrasonography was performed. In addition, GB emptying was monitored by ultrasound at 30-min intervals for 2 h after a mixed meal in randomly chosen, age-matched 25 IDA patients and 26 controls. Fasting volume (FV), residual volume (RV), and ejection fraction (EF) for all GBs were determined. The frequency of GS plus cholecystectomy was significantly higher in IDA patients (15 cases, 13.5%) than in the control group (five cases, 6.2%, p = 0.048). IDA patients with GS plus cholecystectomy were older than those without GS plus cholecystectomy (p < 0.001). FV and EF did not differ between IDA and control groups (p > 0.05). On the other hand, RV was significantly higher in IDA group than in controls (p = 0.035). The frequency of GS in IDA patients was significantly higher than in controls. The increased prevalence of GS in IDA might be explained with impaired GB motility.

An increased prevalence of fibromyalgia in iron deficiency anemia and thalassemia minor and associated factors.

In this study, we evaluated the prevalence of fibromyalgia (FM) in iron deficiency anemia (IDA) and thalassemia minor (TM) patients and associated factors. In addition, we investigated the prevalence of IDA in outpatients with fibromyalgia, and its effect on clinical findings. The study included 205 IDA, 40 TM patients and 100 healthy controls. FM was diagnosed according to 1990 ACR criteria. Whole blood count, biochemical tests, and serum iron parameters were determined. Pain, fatigue, and FM Impact Questionnaire (FIQ) functional item scores were assessed in FM subjects. In addition, the prevalence of IDA in FM patients diagnosed at the Rheumatology Outpatient Clinic was determined. The prevalences of FM in IDA (17.6%) and TM (20%) groups were higher than in controls (6%; p values 0.006 and 0.025, respectively). When IDA patients with FM were compared to those without FM, it was seen that a higher percentage were females, married, and a higher percentage had history of pica (all p values < 0.05). Serum hemoglobin and iron parameters did not differ between IDA patients with and without FM. IDA was detected in 48 (24.5%) of 196 FM patients. FM patients without IDA had higher sleep disturbance scores (p = 0.012) and longer duration of FM (p = 0.045). FM was a common finding in patients with IDA and TM. FM was associated with female sex and history of pica in IDA patients, and not associated with serum hemoglobin and selected iron parameters. The presence of FM in TM had no association with any of the above-mentioned parameters.
