Criteria sets for primary Sjogren's syndrome are not adequate for those presenting with extraglandular organ involvements as their dominant clinical features.

Patients with primary Sjogren's syndrome (pSS) may go undiagnosed or be misclassified due to the insidious nature and wide spectrum of the disease. The available several classification criteria emphasize glandular findings. We aimed to analyze the efficiency of various classification criteria sets in patients diagnosed on the clinical basis by expert opinion and to compare those pSS patients who fulfilled these criteria with those who did not. This is a multicenter study in which 834 patients from 22 university-based rheumatology clinics are included. Diagnosis of pSS was made on the clinical basis by the expert opinion. In this study, we only interviewed patients once and collected available data from the medical records. The European criteria, American-European Consensus Group (AECG) and American College of Rheumatology (ACR) Sjogren's criteria were applied. Majority of the patients were women (F/M was 20/1). The median duration from the first pSS-related symptom to diagnosis was significantly shorter in men (2.5 ± 2.3 vs 4.3 ± 5.9 years) (p = 0 < 0.016). When the European, AECG and ACR Sjogren's criteria were applied, 666 patients (79.9%) satisfied at least one of them. In total, 539 patients (64.4%) satisfied the European, 439 (52.6%) satisfied the AECG, and 359 (43%) satisfied the ACR criteria. Among the entire group, 250 patients (29.9%) satisfied all and 168 (20.1%) met none of the criteria. The rates of extraglandular organ involvements were not different between patients who met at least one of the criteria sets and those who met none. There is an urgent need for the modification of the pSS criteria sets to prevent exclusion of patients with extraglandular involvements as the dominant clinical features.

Pulmonary tuberculosis and tuberculous arthritis of knee joint associated with rheumatoid arthritis treated with anti-tumor necrosis factor (TNF)-alpha medication: a case report.

Tuberculosis infection (TB) is one of the most important problems for the rheumatoid arthritis (RA) patients treated with anti-TNF agents. Pulmonary tuberculosis is the most common clinic form of the TB in these patients. However, tuberculosis arthritis is very rare. We present here a 72-year-old Caucasian woman with seropositive RA, treated with etanercept/adalimumab for the last 2 years, who presented with resistant knee pain and joint effusion. We believe that this treatment caused the tuberculosis in this patient, which is the most worried complication. Interestingly, tuberculosis was in the knee joint at this time.

Are increased carotid artery pulsatility and resistance indexes early signs of vascular abnormalities in young obese males?

PURPOSE: To provide insight into the factors by which obesity in itself may directly lead to early arterial damage, we aimed to determine early sonographic markers of obesity-related vascular dysfunction in young obese males. METHODS: Thirty-five young obese males and 23 age-matched healthy male volunteers were recruited into the study. Common carotid artery pulsatility index and resistance index were calculated from blood flow velocities curves obtained by pulsed Doppler ultrasonography. RESULTS: The mean pulsatility index, resistance index, body mass index, waist circumference, systolic and diastolic blood pressure, homeostasis model assessment for insulin resistance, plasma fasting glucose, insulin, C-peptide, triglycerides, low-density lipoprotein cholesterol, and high-sensitivity C-reactive protein were statistically higher in obese subjects than in healthy controls. CONCLUSIONS: Our results suggest that depressed vessel compliance and increased vascular resistance are features of young, obese, normotensive subjects independently of and in addition to cardiovascular risk factors. As changes in arterial wall properties may be incipient in young obese subjects, future studies will be required to demonstrate whether early intervention such as diet and exercise in this population can improve vascular functions.

The vasoactive intestinal polypeptide (VIP) levels at the patients with ankylosing spondylitis and its association with inflammation markers.

Vasoactive intestinal polypeptide (VIP) is a neuropeptide from secretin/glukagon family. Recently, the importance of VIP is becoming more evident, and it is thought that VIP is playing an important regulatory role between neuroendocrine-immune-gastrointestinal systems. In this study, we have tried to evaluate the potential role of VIP in patients with ankylosing spondylitis (AS). In this study, 40 patients (30 male and 10 female) with AS and 40 healthy controls were included. X-ray examinations and scoring of sacroiliac joints of the patients with AS were done according to 1984 Modified New York Criteria for AS. All patients have been assessed with Bath Ankylosing Spondylitis Disease Activity Index. Platelet counts were significantly higher in study group (P < 0.05) in contrast to levels of the hemoglobin. The mean VIP levels were 4.2 ± 1.8 (pg/mL) for study group and 2.8 ± 0.8 (pg/mL) for controls. These results were statistically significant (P < 0.05). There was not any correlation between plasma VIP levels with CRP, ESR, Hb, BASDAI results and radiological scoring of the patients (P > 0.05) in contrast to our expectations. However, platelet counts and VIP levels were correlated significantly (P = 0.03). Our data demonstrate that VIP tended to be high in patients with AS when compared with healthy subjects and correlated with platelet counts significantly, for the first time at the literature. According to this study, VIP may have potential role in the pathogenesis of AS, and it is a potential candidate for many kinds of therapies.

Can Cytokines be used as an Activation Marker in Rheumatoid Arthritis?

AIMS: The etiopathogenesis of Rheumatoid Arthritis (RA) is not clearly understood. However, the role of the cytokines play an important part in this mechanism. We aimed to bring a new approach to the concept of 'remission' in patients with RA. BACKGROUND: RA is a chronic, autoimmune, inflammatory disease that involves small joints in the form of symmetrical polyarthritis and progresses with exacerbations and remissions. Pain, swelling, tenderness and morning stiffness are typical of the joints involved. Although it is approached as primary joint disease, a wide variety of extra-articular involvements may also occur. It is an interesting pathophysiological process, the exact cause of which is still unknown, with many environmental, genetic and potentially undiscovered possible factors in a chaotic manner. OBJECTIVE: In this cross-sectional study, sedimentation rate (ESR), C- Reactive protein (CRP), Tumor necrosis factor (TNF)-α, soluble-TNF-α receptor (TNF-R), Interleukin (IL)-1B and IL-10 were measured in three groups which were healthy volunteers, patients with RA in the active period, and patients with RA in remission. Disease activity score-28 (DAS-28) was calculated in active RA and RA in remission. METHODS: This study included 20 healthy volunteers, 20 remission patients with RA and 20 active RA patients. Venous blood samples were collected from patients in both healthy and RA groups. RESULTS: RA group consisted 43 (71.6%) female and 17 (28.4%) male. Control group consisted 11 (55%) female and 9 (45%) male. TNF-R was significantly high only in the active group according to the healthy group (p=0.002). IL-10 was significantly high in active RA, according to RA in remission (p=0.03). DAS-28 was significantly high in active RA, according to RA in remission (p=0.001). In the active RA group, ESR and TNF-R had a positive correlation (r:0.442; p=0.048). In the active RA group, there was also a positive correlation between TNF-R and CRP (r:0.621; p=0,003). Both healthy and active RA group had significant positive correlation between ESR and CRP (r: 0.481; p=0.032 and r: 0,697; p=0,001 respectively). CONCLUSION: TNF-R can be the main pathophysiological factor and a marker showing activation. TNF-R can be very important in revealing the effect of TNF on the disease and the value of this effect in the treatment and ensuring the follow-up of the disease with CRP instead of ESR in activation.

Risk of sarcopenia in hospitalized patients and related clinical factors: a multicenter study from Turkey.

PURPOSE: To investigate the risk of sarcopenia in hospitalized older patients and to assess the associations between sarcopenia risk and health care outcomes including dependency, malnutrition, and dysphagia. METHODS: This multicenter cross-sectional study was a part of the annual National Prevalence Measurement of Quality of Care (LPZ) in Turkey. Hospitalized patients age 65 and older were included in the study. The SARC-F was used to assess risk of sarcopenia. Dependency was appraised according to the Care Dependency Scale (CDS). Nutritional status was established with respect to the Malnutrition Universal Screening Tool (MUST). Dysphagia was screened by two structured questions. RESULTS: A total of 492 patients were included in the analysis. Two hundred and forty patients (48.8%) were at risk of sarcopenia. Sarcopenia risk was more prevalent among women (p = 0.007) and patients with risk of sarcopenia were older (p < 0.001). Hospital stay was longer and malnutrition and dysphagia were more prevalent in patients with sarcopenia risk than without (all p < 0.001). All nutritional interventions were applied mostly to patients with sarcopenia risk than without. In multivariate analysis, advanced age (OR: 1.068, CI 1.032-1.104, p < 0.001), female gender (OR: 2.414, CI 1.510-3.857, p < 0.001), and dependency (OR: 5.022, CI 2.922-8.632, p < 0.001) were independently associated with sarcopenia risk. CONCLUSIONS: Sarcopenia risk is related with unfavorable outcomes in hospitalized patients. Primarily older female patients are at risk for sarcopenia. It is important to recognize sarcopenia at an early stage and to prevent its progression, before dependency develops. The SARC-F may be a useful tool for screening sarcopenia risk in hospitalized patients.

Cytokine profile in Behçet uveitis.

OBJECTIVES: Investigate the role of cytokines in Behçet uveitis. BACKGROUND: Cytokines may take part in this pathogenetic mechanism. Elevated and/or altered levels of specific cytokines have been found in patients with Behçet's disease in many studies. METHODS: Twenty patients with Behçet uveitis and 20 patients with Behçet's disease without uveitis were included to the study in compliance with International Study Group Criteria. Twenty non-Behçet uveitis patients were included in the study. In this group, active uveitis was found in 30 % and arthritis in 35% of patients. Serum levels of cytokines (Interleukin-2-4-6-8, IL-2-4-6-8), tumor necrosis factor-alpha, TNF-alpha) and local growth factor (vascular endothelial growth factor, VEGF) were measured. RESULTS: Levels of all cytokines were highest in Behçet patients without uveitis except for IL-2 and IL-6. These cytokines were also highest in patients with non-Behçet uveitis too. Despite the tendency of this distribution of cytokines, only three cytokines, TNF-alpha, IL-8 and IL-4 were significantly different from the controls. The levels of TNF-alpha, IL-8 and IL-4 were significantly lower in patients with Behçet uveitis than in Behçet patients without uveitis. Interestingly, the levels of IL-2 and IL-6 were statistically similar in all groups. VEGF showed no significant difference between the studied and control groups. However, in contrast to cytokines, only the levels of VEGF were correlated with the activity of uveitis (p<0.05). CONCLUSION: Consistent with previous reports of different immune effectors in Behçet uveitis, it may be suggested that its underlying immunopathogenesis may be much different from other causes of endogenous uveitis (Tab. 3, Fig. 1, Ref. 20).

The association of endoplasmic reticulum aminopeptidase-1 (ERAP-1) with Familial Mediterranean Fever (FMF).

BACKGROUND: The ERAP1 gene cleaves the receptors and reduces their ability to transmit chemical signals to the cell that affect the process of inflammation and, secondly, it cleaves many types of proteins into small peptides that are recognized by the immune system. OBJECTIVE: ERAP-1 gene mutations may create a sensitivity for Familial Mediterranean Fever (FMF). METHOD: We included 15 FMF patients with the M694 (+) mutation in the study in order to exclude patients without pyrin gene mutations and create a homogeneous study group. Fifteen patients with ulcerative colitis formed the control group. RESULTS: There wasn't any case without ERAP-1 gene mutations. At least one mutation at exon 3 or exon 10 was found in all cases in both groups. There were 14 ERAP-1 gene mutations at exon 10 and 11 at exon 3 in patients with FMF. Interestingly, if there were ERAP-1 gene mutations at exon 3, a p.Arg127 Pro (c.380 G>C) mutation always existed for three FMF patients with polymorphic mutations at this exon. There were 11 ERAP-1 gene mutations at exon 10 and 12 gene mutations at exon 3 in patients with ulcerative colitis. Exon 3 mutations were usually single p.Arg127 Pro (c.380 G>C) mutations for 12 patients with ulcerative colitis as seen in the patients with FMF. The single mutation was always p.Ser453 Ser (c.1359T>C) for patients with ulcerative colitis at exon 10. CONCLUSION: There are more ERAP-1 mutations in the FMF group in comparison to the ulcerative colitis group. So, there may be a strong susceptibility to ERAP-1 gene mutations in FMF patients according to our results. However, further studies with larger study and control groups are needed.

Therapeutical potential of autologous peripheral blood mononuclear cell transplantation in patients with type 2 diabetic critical limb ischemia.

AIM: The aim was to evaluate the therapeutic effectiveness of granulocyte colony-stimulating factor (G-CSF) mobilized peripheral blood mononuclear cells (PBMNCs) in critical limb ischemia (CLI) of type 2 diabetic patients. METHOD: Forty diabetic patients with CLI were enrolled and randomized to treatment and control groups. In the treatment group, the patients received subcutaneous injections of recombinant human G-CSF (30 MU/day) for 5 days to mobilize stem cells. PBMNCs were collected and transplanted by multiple intramuscular injections of 1 ml in 1-1.5-cm depth into ischemic limbs. RESULTS: At the end of 12 weeks of follow-up, the baseline and end point results in transplant group were as follows: Fontaine score improved from 3.8±03 to 3±0.5 (P=.0001), ankle brachial pressure index increased from 0.68±0.24 to 0.87±024 (P=.001), transcutaneous oxygen increased from 33±14 mmHg to 44±10 mmHg (P=.0001), and 6-min walking distance improved from 280±82 m to 338±98 m (P=.0001). Pain score decreased from 8.2±1.3 to 5.63±1.6 (P=.001), and the number of patients with limb ulcers was reduced from 9/20 (45%) to 3/20 (15%) (P=.031). In the control group, Fontaine score, 6-min walking distance, and pain score were improved; ankle brachial pressure index and transcutaneous oxygen pressure were not improved. The number of patients with limb ulcers did not change in the control group. There are improvement in amputation rates, collateral vessel development, and number of limb ulcers healed. CONCLUSIONS: These results indicate that the autologous transplantation of G-CSF that mobilized PBMNCs in CLI diabetic patients is safe and effective in patient compliant reduction and improved perfusion.

High Frequency of Inherited Variants in the MEFV Gene in Acute Lymphocytic Leukemia.

In the present study, we aimed to determine the frequency of inherited variants in the MEFV (Mediterranean FeVer), the gene responsible for familial Mediterranean fever (FMF), gene in patients with acute lymphocytic leukemia (ALL). The eight MEFV gene variants (M694I, M694V, M680I (G/C-A), V726A, R761H, E148Q and P369S) were detected in 36 patients with ALL and 65 healthy controls; none had own and/or family history compatible with FMF. We identified 11 heterozygous inherited variants in the MEFV gene in both ALL patients and controls. The mean overall frequency of inherited variants in the MEFV gene rate was higher in ALL patients than healthy controls (P = 0.040). It is interesting to note that M680I/0 is predominant variant in patients with ALL. In addition, E148Q variant frequency was also significantly higher in the patient group than the controls (P = 0.012). In conclusion, overall frequency of inherited variants in the MEFV gene was found to be higher in patients with ALL. Based on the present data, it is difficult to reach a definitive conclusion regarding the possibility that inherited variants in the MEFV gene could represent a causative role in ALL. However, the data of our study may provide some new insights in understanding of individual genetic differences in susceptibility to these neoplasms. Further investigations are needed to determine the actual role of inherited variants in the MEFV gene in pathogenesis of ALL.

Increased iron and oxidative stress are separately related to cognitive decline in elderly.

AIM: The aim of this study is to examine the relation between body iron, oxidative stress and cognitive function in elderly. METHODS: Eighty-seven elderly residents from nursing homes were the subjects of our study. Cognitive status was screened by the Mini-Mental State Examination (MMSE). Of the 87 eligible subjects, 46 patients who obtained 24 or fewer points on the MMSE scale were considered as subjects with cognitive dysfunction. The control group consisted of 41 subjects who obtained more than 24 points on the MMSE. Routine biochemical analyses, parameters of iron metabolism, malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) were determined in all subjects. RESULTS: There were statistically significant increases in serum iron, transferrin saturation, ferritin and MDA levels; whereas there was a statistically significant decrease in serum GSH-Px enzyme activity and serum sodium levels in subjects with cognitive dysfunction. A significant negative correlation was found between serum iron, transferrin saturation, ferritin and MMSE score. There was a negative correlation between MMSE score and serum MDA; however, a positive significant correlation was found between MMSE score and both GSH-Px enzyme activity and serum sodium. CONCLUSION: Our study provides evidence of increased markers of iron deposition and oxidative stress in patients with cognitive dysfunction. It seems likely that these markers negatively affect the MMSE score. Interestingly, we did not find any correlation between the markers of iron deposition and oxidative stress. Future studies will be required to demonstrate whether diminishing iron and oxidative stress will enhance MMSE score and thereby ameliorate cognitive impairment.

Effect of uncomplicated obesity on QT interval in young men.

INTRODUCTION: QT prolongation and obesity are associated with ventricular arrhythmia and sudden cardiac death. The relationship between uncomplicated obesity and QT interval prolongation is not clear. OBJECTIVES: The aim of the study was to investigate the effects of uncomplicated obesity on QT interval in young men. PATIENTS AND METHODS: A total of 122 men, including 59 obese patients and 63 controls, were recruited into the study. Patients with hypertension, diabetes mellitus, and ischemic heart disease were ineligible. Body mass index (BMI) of all patients was calculated. QT interval was measured from the precordial lead--V5, and corrected QT (QTC) was calculated using the Bazett's formula. RESULTS: Mean age, BMI, and waist circumference (WC) of obese patients and controls were as follows: 22.0 +/-3.0 years, 36.2 +/-2.2 kg/m(2), and 114 +/-8.1 cm; 22.6 +/-2.9 years, 24.7 +/-2.5 kg/m(2), and 81.6 +/-7.5 cm, respectively. There was a statistically significant difference between the obese and control groups with regard to BMI and WC (P <0.001). Furthermore, statistically significant differences were observed between the 2 groups in terms of QTC (407.9 +/-17.1 ms vs. 397.7 +/-14.0 ms, respectively, P <0.001), systolic (126.9 +/-8.2 mmHg vs. 114.2 +/-11.1 mmHg, respectively, P <0.001) and diastolic blood pressure (78.3 +/-4.5 mmHg vs. 66.9 +/-10 mmHg, respectively, P <0.001). There was a positive correlation between QTC interval and both WC (r = 0.357, P <0.001) and BMI (r = 0.424, P <0.001). There was no association between QTC and blood pressure. CONCLUSIONS: Uncomplicated obesity in young men is associated with QT interval prolongation. Weight gain may inversely affect cardiac repolarization in uncomplicated obesity.

Albumin, hemoglobin, body mass index, cognitive and functional performance in elderly persons living in nursing homes.

The aim of this study is to produce the relation between cognitive and functional performance and some biochemical parameters in elderly population. So, we searched for the correlation between the activities of daily living (ADL), mini-mental state examination (MMSE) and body weight, age, hemoglobin, albumin, serum sodium level of 180 elderly people in five nursing homes. Face-to-face interviews and questionnaires were applied to evaluate ADL. To evaluate the cognitive function we used the MMSE. The average age of 180 people contacted was 71.5+/-5.1 (+/-S.D.), ranging 65-91 years; 112 of them were women (62.2%), 68 were men (37.8%). Of these elderly people, 25% had no medically diagnosed illnesses, whereas 17 of them (9.4%) were bedridden. There was a positive correlation between ADL and hemoglobin, albumin, body weight, cognitive function parameters and a negative one with age and serum sodium. There was a positive correlation between cognitive functions and hemoglobin, body weight, ADL and a negative one with serum sodium. Hemoglobin concentrations indicating anemia were observed in 30% of subjects, 3.9% of them had hyponatremia and 26.7% displayed a hypernatremia. There was a positive correlation between cognitive and physical function scores and hemoglobin, albumin levels in elderly patients. These results suggest that restoration of hemoglobin and albumin levels could improve cognitive and physical functional status in the elderly population.

Relationship between anaemia and cognitive functions in elderly people.

BACKGROUND: The primary goal of the present study was to investigate the effects of anaemia on the cognitive functions and daily living activities in elderly people. METHODS: This sectional study was performed using 180 elderly people. Face-to-face interviews and questionnaires were conducted to evaluate daily activities. To evaluate cognitive functions we used the Folstein's Mini-Mental State Examination (MMSE). RESULTS: The mean age of the anaemic group and the nonanaemic group were 76.0+/-11.7 and 72.5+/-15.2 years, respectively. The average haemoglobin level among the anaemic population was 10.4 g/dL compared with 13.6 g/dL among the nonanaemic population; a statistically significant difference. There was more impairment in functional status (Katz ADL) (6.8+/-4.3 vs 9.3+/-3.7) and cognition (MMSE) (17.9+/-6.4 vs 21.7+/-6.7) in anaemic than nonanaemic groups, respectively. Albumin and body mass index were lower and the percentage of two or more comorbidities was higher in anaemic group compared to the nonanaemic group, which was a statistically significant variation. The anaemic group was more dependent in terms of bathing, dressing, toileting and transferring. CONCLUSION: In the elderly anaemic group, the dependency for daily activities that require physical effort was higher compared to the nonanaemic group. The MMSE score in the elderly anaemic group was lower than subjects who had normal haemoglobin levels. We conclude that anaemia may impair cognitive functions and some daily living activities in the elderly.

High frequency of MEFV gene mutations in patients with myeloid neoplasm.

We aimed to investigate the rate of MEFV, the gene mutated in familial Mediterranean fever, mutations in patients with myeloid neoplasm and to determine if known mutations of MEFV cause a tendency for myeloid neoplasms. The frequency of the five most common MEFV gene mutations (M694V, M680I, V726A, E148Q and M694I) was determined in 26 patients with myeloid neoplasm. We identified 1 homozygous (E148Q/E148Q), 1 compound heterozygous (M694V/E148Q) and 5 heterozygous MEFV gene mutations; none had their own and/or family history compatible with familial Mediterranean fever. The mean overall mutation rate was 0.269. We found a high frequency of carriers in patients with myelodysplastic syndrome (66.6%), polycythemia vera (33.3%) and acute myeloid leukemia (28.6%). However, there was no MEFV gene mutation in patients with chronic myeloid leukemia. In conclusion, this study reports for the first time a possibly high prevalence of MEFV gene mutations in patients with myeloid neoplasm, especially myelodysplastic syndrome, polycythemia vera and acute myeloid leukemia. Our findings could open new perspectives for MEFV gene mutations in myeloid neoplasms and its association with tumor promotion. Further research is needed to determine the actual role of MEFV gene mutations in these malignancies.

Familial Mediterranean fever attacks do not alter functional and morphologic tissue Doppler echocardiographic parameters.

The aim of this study is to investigate the tissue Doppler echocardiographic (TDE) characteristics of acute familial Mediterranean fever (FMF) attack on young Turkish males. Thirty-four young males with FMF were investigated utilizing echocardiography both before and after FMF attacks. Echocardiographic findings were assessed by two cardiologist utilizing Vingmed system V echocardiography machine and a 2.5 MHz probe by two-dimensional and color Doppler examination, as well as tissue Doppler parameters. The incidence of pericardial effusion was found to be 23.3% during acute FMF attack. There was no significant difference between the patients in attack-free period and attack period with respect to TDE measurements. TDE measurements did not differ between the patients with and without pericardial effusion. There was no correlation between pericardial effusion and disease duration, family history, and physical findings. In conclusion, our results suggest preserved systolic and diastolic ventricular functions in attack period. Pericardial effusion is not associated with impaired TDE parameters.

Increased asymmetric dimethylarginine levels in young men with familial Mediterranean fever (FMF): is it early evidence of interaction between inflammation and endothelial dysfunction in FMF?

OBJECTIVE: Unlike in many other chronic inflammatory rheumatic diseases, studies investigating endothelial dysfunction and atherosclerosis in familial Mediterranean fever (FMF) are limited, and the results are controversial. Asymmetric dimethylarginine (ADMA) is considered an indicator for endothelial dysfunction and a sensitive marker for cardiovascular risk. There have been no reports on serum ADMA levels in patients with FMF. METHODS: We aimed (1) to determine serum ADMA concentrations in 38 young male patients with FMF and 23 age- and body mass index-matched healthy volunteers; (2) to evaluate its correlations with MEFV mutations, C-reactive protein (CRP) levels, and lipid profile; and (3) to compare effects of colchicine on circulating ADMA concentrations. RESULTS: In patients with FMF, ADMA and CRP levels were higher than in healthy controls. The mean levels of ADMA and CRP were higher during acute attacks than in attack-free periods. Patients taking colchicine had lower serum ADMA levels than non-colchicine users. There was a positive strong correlation between ADMA and CRP in patients with FMF. Stepwise linear regression analysis in patients with FMF revealed that age and CRP levels were independently associated with serum ADMA levels. CONCLUSION: Our data imply that higher serum ADMA levels in FMF may indicate inflammation-related "endothelial dysfunction." It seems likely that regular use of colchicine is effective in preventing the development of and reversing not only amyloidosis but also endothelial dysfunction in patients with FMF.

Ulcerative necrosis of the glans penis resulting from polyarteritis nodosa.

Polyarteritis nodosa (PAN) may be systemic or isolated in distribution and may involve virtually any organ or tissue in the body. We report an unusual case of PAN with the clinical features of both penile and renal involvement in a 21-year-old man diagnosed incidentally by pathologic examination of the nephrectomized left kidney. Systemic and surgical therapeutic procedures were applied and his symptoms resolved within 6 weeks. Penile ulceration is a rare but serious manifestation of PAN that needs prompt and aggressive treatment.

A case of Weil's syndrome developing steroid resistant immune haemolytic anaemia.

Weil's syndrome is known in a serious clinical form, but the development of immune haemolytic anaemia related to Leptospira in human beings is a very rare clinical presentation, and we encountered only 1 case report in a literature scan. In this paper we present a case of Weil's syndrome in which immune haemolytic anaemia findings, and haemolysis could only be controlled by intravenous immunoglobulin (IvIg) treatment.

Prophylactic effect of highly selective COX-2 inhibition in acute monosodium urate crystal induced inflammation in the rat subcutaneous air pouch.

OBJECTIVE: To examine the ability of rofecoxib prophylaxis to blunt the effect of monosodium urate (MSU) crystal inflammation induced in the rat subcutaneous air pouch. METHODS: Eight rats were used in each of 4 groups. On day one, air was injected subcutaneously to create the pouches and gavage feedings were started with placebo or 2 different doses of rofecoxib. Six days later MSU crystals or saline were injected into the pouches. Twenty-four hours later, rats were examined, sacrificed, and pouch fluid studied. RESULTS: Rofecoxib 15 or 30 mg/kg given for 6 days before MSU crystal injection into rat air pouches significantly suppressed the inflammation following injection of 10 mg crystals (p = 0.001) and tended to suppress the milder inflammation induced by 5 mg MSU. Greater effects on phagocytosis were seen with 30 mg/kg rofecoxib. Tumor necrosis factor-alpha levels in pouch fluid measured by ELISA were not suppressed by the rofecoxib. CONCLUSION: Prophylactic use of this cyclooxygenase 2 (COX-2) selective inhibitor in this pilot study suppressed acute MSU crystal induced inflammation. Effects on cytokines need further investigation. COX-2 inhibitors deserve consideration for prophylactic use in interim gout.
