Demographic and clinical features of gout patients in Turkey: a multicenter study.

Gout results from multifactor interactions between gender, age, genetic and environmental factors. Environmental factors underlying gout and precipitating factors triggering acute attacks might vary in different populations with different lifestyles. In this study, we aimed to collect data regarding the demographic and clinical features, comorbid factors, and precipitating factors associated with the initiation of acute attacks in gout patients in Turkey. A total of 312 patients were included in this study (mean age, 58.8 ± 13.8 years; female/male ratio, 55/257). The demographic features, alcohol intake, clinical and laboratory features, and comorbid conditions including obesity, diabetes mellitus, hyperlipidemia, hypertension, and coronary heart disease were noted in a standard questionnaire. Precipitating factors initiating acute attacks (if any) were also noted. The patients were divided into 4 groups according to the region of location as central Anatolian region, southeast Anatolian region, Aegean region, and Trakya region. Our results were compared according to the gender and the location of the patients. The mean age at the start of the symptoms was 10 years higher in women (60.4 ± 14.8 and 50.6 ± 13.5 years in women and men, respectively, p < 0.001).Obesity was present in 40.1 %, diabetes mellitus in 17.9 %, hyperlipidemia in 30.1 %, hypertension in 53.5 %, coronary artery disease in 17 %, and nephrolithiasis in 21.8 % of patients. Precipitating factors triggering gout flares were as follows: diet (high consumption of meat or fish) in 46.5 %, alcohol consumption in 15.7 %, diuretics in 8.3 %, diet or diuretics in 5.1 %, diet or alcohol in 4.5 %, diet or alcohol or diuretics in 1.6 %, others in 4.2 %, and none in 14.1 %. The presence of diabetes and diuretic use was more common among women. Use of diuretics is a more common trigger for gout flares among women. On the other hand, various comorbid conditions, such as obesity and hypertension, and triggers for gout flares may differ between patients living in different geographic regions. In summary, we reported the first data regarding clinical and demographic characteristics of gout in Turkey. The majority of our patients could describe at least one "trigger" that initiated gout flare. Both comorbid conditions and triggers of attack might differ between men and women, and in different geographic areas. Better knowledge of the modifiable risk factors can be useful for the management strategy to optimize long-term patient outcomes in local clinics.

Differential diagnosis of elevated erythrocyte sedimentation rate and C-reactive protein levels: a rheumatology perspective.

OBJECTIVE: In the case of high erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels, the diagnosis of the underlying disease can be challenging especially in serologically unrevealing patients who have nonspecific clinical findings. We aimed to investigate the final distribution of definitive diagnoses in patients who initially presented with nonspecific clinical findings and sustained elevations in serum ESR/CRP levels. MATERIAL AND METHODS: The medical records of patients hospitalized in a rheumatology clinic between January 2010 and January 2011 were retrospectively analyzed. The patients were classified into two main groups: those with previously diagnosed underlying rheumatic disease (RD) and those without. The groups were analyzed for the final distribution of definitive diagnoses. RESULTS: Out of 112 patients in the general study population, 47 had a previous RD and 65 had no previous history of RD. In these 65 patients, the most common etiology of nonspecific elevations in ESR/CRP levels was new onset RD (52.3%). Polymyalgia rheumatica (PMR) was the most common new onset RD (38% of all new onset RD) followed by seronegative rheumatoid arthritis. The incidences of infections and malignancies were 24.6% and 9.2%, respectively. CRP levels were significantly higher in infections when compared with new onset RD or malignancies (p<0.05). In patients with previous RD, the flare of the underlying disease was the most common etiology of nonspecific elevations in ESR/CRP levels (n=39, 83%, 20 female/19 male). CONCLUSION: Extraordinarily high levels of serum CRP in a patient with nonspecific clinical findings should raise suspicion for non-rheumatic diagnoses, such as infection and malignancy, even in the presence of a previously diagnosed RD. Advanced radiological investigation is justified in these cases to rule out malignancy.

Free testosterone levels and implications on clinical outcomes in elderly men.

BACKGROUND AND AIMS: Aging is accompanied by a progressive decline in serum testosterone. Evidence concerning the clinical manifestations of low serum testosterone levels is contradictory. We aimed to examine the age-related decline in testosterone and the possible clinical outcomes, including erectile dysfunction, prostatism, cognitive function, daily life activities, depression, and osteoporosis. METHODS: One hundred and twenty men underwent comprehensive geriatric assessment. Testosterone and free testosterone levels were measured, geriatric assessment scales, International Index of Erectile Function (IIEF) and International Prostate Symptom Scale (IPSS) were performed, and bone mineral densities were determined. RESULTS: The mean age of the 120 men was 73.8+/-5.90. A significant decrease in testosterone and free testosterone levels with increasing age was determined (p=0.021). It was also found that erectile dysfunction, as determined by IIEF (r=0.66, p<0.001), and symptoms of prostatism determined by IPSS (r=-0.23, p=0.016), were significantly associated with low free testosterone levels. Laboratory parameters, obesity, osteoporosis, cognitive function, daily life activities, and cardiovascular diseases were not significantly different between groups with low and normal free testosterone levels. CONCLUSION: Age-related decrease in free testosterone may lead to erectile dysfunction and symptoms of prostatism in elderly men.
