Clinical features and personality traits associated with psychological distress in systemic sclerosis patients.

OBJECTIVE: The aim of the present study was to identify certain clinical parameters and personality characteristics associated with various forms of psychopathology in systemic sclerosis (SSc) patients. METHODS: Fifty-six SSc patients participated in the study, and 74 healthy participants served as controls. A wide range of clinical information was collected, and the following self-report instruments were used: General Health Questionnaire, Symptom Distress Checklist-90-R, Defense Style Questionnaire, Sense of Coherence (SOC) Scale, and Hostility and Direction of Hostility Questionnaire. RESULTS: The odds of being assessed with a psychiatric diagnosis upon interview were 4.5 times greater among SSc patients compared with controls. Disease duration and lower rates of SOC were found to be associated with elevated symptoms of general psychological distress. Elevated symptoms of depression were strongly associated with esophageal involvement, hostility, and defense style used. Elevated symptoms of anxiety were mainly associated with arthritis-related painful conditions and SOC, while psychotic-like symptoms were only associated with age and a specific personality structure. CONCLUSIONS: SSc patients experience elevated symptoms of psychological distress. Several clinical parameters are associated with distress, but the role of various personality traits could not be disregarded. Early psychiatric assessment and intervention could prevent psychological distress in SSc patients.

Multiple sclerosis associated with systemic sclerosis.

Multiple sclerosis (MS) has been increasingly reported in association with other autoimmune diseases not primary affected the nervous system. The coexistence of MS and systemic sclerosis (SSc) has been rarely described. We report here the case of a 46-year-old female patient with longstanding MS since the age of 26, who developed SSc 12 years later. Her MS was of the relapsing-remitting type, but the definite diagnosis was not made until the age of 33. MS diagnosis was based on medical history, magnetic resonance imaging (MRI) studies and positive cerebrospinal fluid analysis. One year after the diagnosis of MS, she developed Raynaud's phenomenon, skin tightness and hypopigmented patches, suggestive of scleroderma. Further investigation with laboratory studies, including serology, hand and chest X-rays, and chest computerized tomography scan confirmed the SSc diagnosis. Our report highlights the interesting association between MS and SSc that may be due to an overlapping pathogenetic mechanism for both processes.

Esophageal involvement in scleroderma: gastroesophageal reflux, the common problem.

OBJECTIVES: Systemic sclerosis (SSc) is a multisystem disease characterized by abnormalities of small blood vessels, and fibrosis of the skin and internal organs including gastrointestinal tract. This article reviews the esophageal involvement in SSc, emphasizing the gastroesophageal reflux, which is a common problem in SSc patients. METHODS: We conducted a Medline search from 1966 to 2005. The keywords "systemic sclerosis," "esophageal involvement," "gastroesophageal reflux," "esophagitis," and "treatment" were used. RESULTS: The gastrointestinal tract is frequently affected in diffuse and limited disease. Although any part of the gastrointestinal tract can be involved, esophageal disease occurs in nearly all patients with SSc. Common esophageal manifestations in SSc include motility abnormalities and gastroesophageal reflux (GER), Barrett's esophagus, adenocarcinoma, infectious esophagitis, and drug-induced esophagitis. Common complications of GER include esophagitis with erosions and bleeding and stricture formation. Extraesophageal manifestations of GER include mouth ulcers, chronic cough, hoarse voice, sore throat, pharyngitis, laryngospasm, asthma, and recurrent pneumonia. Diagnostic procedures used in the investigation of esophageal involvement include barium esophagram, esophageal manometry, 24-hour ambulatory pH, and endoscopy. Treatment of GER in SSc includes behavioral modification and medical therapy, mainly with proton pump inhibitors. Surgical intervention has a limited role in the management of GER in selected SSc patients. CONCLUSIONS: Esophageal involvement is frequent in SSc patients. Gastroesophageal reflux may cause high morbidity. Careful examination of the patients reveals gastrointestinal abnormalities even in patients without symptoms. Appropriate treatment of esophageal involvement ameliorates symptoms and prevents complications.

Epidemiology of systemic sclerosis in northwest Greece 1981 to 2002.

OBJECTIVES: To investigate the incidence and prevalence, as well as the mortality and survival rates, of systemic sclerosis (SSc) in a defined area of northwest Greece with a population of about 500,000 inhabitants. MATERIALS AND METHODS: Cases have been recorded from the following sources: (1) inpatients and outpatients referred to the Rheumatology Clinics of the Ioannina University Hospital and the Ioannina General Hospital; (2) patients referred to the private rheumatologists practicing in the study area. All patients recorded between 1/1/1981 and 31/12/2002, resident in the study area, were included in the study. Diagnosis was based on the American College of Rheumatology classification criteria for SSc. Incidence and prevalence rates were calculated as number of cases per 10(5) inhabitants. Population data were based on the National Census of 1981, 1991, and 2001. RESULTS: The age-adjusted prevalence of SSc was 15.40 cases/10(5) inhabitants on 31/12/2002. A total of 109 new cases were diagnosed during the study period, giving a mean annual age-adjusted incidence rate of 1.10 cases/10 5 inhabitants. There were 98 women and 11 men, giving a ratio of 8.9/1. Limited SSc was diagnosed in 75% and diffuse in 25% of the patients. Esophageal involvement was found in 59%, lung involvement in 56%, and renal disease in 5%. Thirty-six deaths were recorded during the study period in this incidence cohort. The 5-year survival rate was 83% and the 10-year survival rate was 70%. CONCLUSIONS: The incidence and prevalence of SSc in northwest Greece were found to be lower than those of the USA and Australia, and higher than those of northern European countries and Japan. The survival rates were similar to those reported by other studies.

Radiological cervical spine involvement in patients with rheumatoid arthritis: a cross sectional study.

OBJECTIVE: To investigate the frequency and the severity of radiological cervical spine involvement in patients with rheumatoid arthritis (RA). METHODS: We investigated 165 consecutive unselected patients with RA who fulfilled the revised American College of Rheumatology criteria for RA. All patients had a complete physical and laboratory evaluation. Patients had a radiological evaluation that included hand and wrist radiographs, as well as cervical spine radiographs in anteroposterior, lateral, and lateral in full flexion views. Hand radiographs were evaluated according to the Larsen criteria, while cervical radiographs were evaluated according to Winfield classification. RESULTS: There were 143 women and 22 men, with a mean age of 59.6 +/- 12.5 and disease duration 12.3 +/- 13.9 years. Positive rheumatoid factor was found in 63.6% of patients. One hundred forty-six patients presented radiological findings related to cervical spine involvement: atlantoaxial subluxations were found in 20.6% and erosions of the odontoid process in 2.4%; none presented vertical subluxation. Subaxial subluxations were found in 43.6%, disc space narrowing at C2-C3, C3-C4, C4-C5 levels in 66.1%, and vertebral plate sclerosis and erosions in 43.6%. CONCLUSION: Cervical spine radiological involvement is a frequent finding in our patients with RA, but the severity of the disease is rather mild, possibly related to the ethnic background.

Disease modifying antirheumatic drugs in early rheumatoid arthritis: a longterm observational study.

OBJECTIVE: To investigate the effectiveness, toxicity, and drug survival in an observational longterm study of patients with early rheumatoid arthritis (RA). METHODS: Four hundred twenty-eight patients with early RA were investigated between January 1987 and December 1995. All patients had a disease duration of less than one year and had not been previously treated with any disease modifying antirheumatic drug (DMARD). The following drugs were introduced at the doses specified: hydroxychloroquine (HCQ) (200-400 mg/day), D-penicillamine (D-Pen) (500 mg/day), sulfasalazine (SSZ) (2-3 g/day), auranofin (6 mg/day), intramuscular gold (IM gold, 50 mg/week), methotrexate (MTX) (0.15 mg/kg/week, per os), cyclosporin A (CSA) (3 mg/kg/day), azathioprine (AZA) (2-3 mg/kg/day), cyclophosphamide (CYC) (1-2 mg/kg/day). RESULTS: Three hundred eighty-three patients were treated with one DMARD for at least 6 months. Sixty-five percent of patients were seropositive. The disease duration was 9.2 (3.1) months and the followup period of 12.7 (4.8) years, ranging from 7 months to 13 years. The drugs of first choice were: D-Pen (32%), HCQ (30%), MTX (21%), CSA (8%), and IM gold (7%). After the 2nd, 3rd, and 4th prescriptions, MTX was the most popular drug (27%), while D-Pen and HCQ were prescribed less frequently. The longest drug survival was seen in MTX treated patients, followed by CSA, without significant differences between them. D-Pen, HCQ, and IM gold had the largest dropout rate. The main causes for drug discontinuation were drug inefficacy (HCQ), followed by adverse drug reactions (D-Pen). CONCLUSION: It appears that MTX has the longest survival time, with CSA following in second place. The main reasons for discontinuation of treatment were drug inefficacy, followed by adverse drug reactions.
