Previous research has identified two main problems of sexuality in female rheumatoid arthritis (RA) patients: difficulties in sexual performance and diminution of sexual desire and satisfaction. This study attempts to determine the clinical and psychological factors significantly contributing to sexual disability and dissatisfaction in female RA patients. Ninety consecutive female RA outpatients were assessed by a gynecologist. After excluding patients who were not sexually active and those with genital tract abnormalities, 52 patients were examined and investigated rheumatologically and given questionnaires assessing sexual performance, desire, and satisfaction, as well as demographic variables, pain, disability, anxiety, and depression. Following a correlation analysis, the contributions of demographic, disease, and psychological variables to sexual disability and dissatisfaction were explored by hierarchical and stepwise regression. Thirty-two patients (62%) had difficulties in sexual performance including nine patients (17%) who were totally unable to engage in sexual intercourse because of arthritis. Sexual desire or satisfaction were diminished in 24 patients (46%) and completely lost in 24 patients (46%). Sexual disability was not significantly correlated with any psychodemographic variables, but with parameters of disease activity (p<0.001), Health Assessment Questionnaire (HAQ)-disability (p<0.001), hip (p<0.001) but not knee joint disease, seropositivity (p<0.05), and diminished desire (p<0.05). However, HAQ-disability and hip joint disease were the only independent and significant determinants of sexual disability in the regression model after controlling for the effects of age and disease duration. These variables together explained 64% of the variance of sexual disability. On the other hand, pain (p<0.001), age (p<0.05), and depression (p<0.05) were the significant determinants in the regression model for sexual dissatisfaction, all together contributing 36% of its variance. More than 60% of female RA patients experience variable degrees of sexual disability and diminished sexual desire and satisfaction. Difficulties in sexual performance are related more to overall disability and hip involvement, while diminished desire and satisfaction are influenced more by perceived pain, age, and depression.

Chronic low back pain (LBP) is an extremely common problem in practice, where it is often labeled idiopathic. No sufficient studies have been conducted to analyze the contribution of hypovitaminosis D to the etiology of chronic LBP in populations wherein vitamin D deficiency is endemic. The present study was, therefore, carried out to examine hypovitaminosis D and its determinants in female patients with chronic LBP during the childbearing period. Sixty female patients complaining of LBP lasting more than 3 months were clinically studied rheumatologically and neurologically. Questionnaires and indices quantifying risk factors associated with vitamin D deficiency were utilized. Biochemical assays of serum calcium, phosphorus, alkaline phosphatase (ALP), parathormone (PTH), and 25-hydroxyvitamin D (25 OHD) were performed and compared to those of 20 matched healthy controls. The determinants of vitamin D levels in patients were examined by stepwise regression. Patients with LBP had significantly lower 25 OHD levels (p < 0.05) and significantly higher PTH (p < 0.05) and ALP (p < 0.001) than controls, although there were no significant group differences in calcium and phosphorus. Hypovitaminosis D (25 OHD < 40 ng/ml) was found in 49/60 patients (81%) and 12/20 (60%) of controls, with an odds ratio of 2.97. Although many risk factors related to sun exposure, clothing, diet, and pregnancy were significantly correlated with vitamin D levels in patients, only limited duration of sun exposure, contributing 55% to the variance of 25 OHD, limited areas of skin exposed (13%), and increased number of pregnancies (2%), were significant determinants of vitamin D levels in patients. Despite the sunny climate, hypovitaminosis D is prevalent among Egyptian women in the childbearing period, especially those presenting with chronic LBP, where it is associated with hyperphosphatasia and hyperparathyroidism, without alterations in serum calcium. The major determinant of hypovitaminosis D in our patients is limited sun exposure.

The objective of our study was to determine the prevalence of neuropsychiatric manifestations and anti-ribosomal P antibodies (aRP) in SLE and to examine the diagnostic utility and associations of aRP with neuropsychiatric and other disease manifestations. Thirty two consecutive SLE patients, diagnosed according to the updated 1997 ACR criteria, were studied. A full medical history, rheumatological, neurological, psychiatric examination, and psychometric evaluation, including a battery of tests for cognitive dysfunction and the Symptom Checklist-90-Revised depression and anxiety scales were administered to all patients. Disease activity was scored using the SLEDAI. Neuropsychiatric manifestations were diagnosed and categorized according to the 1999 ACR case definitions for 19 NPSLE syndromes. Laboratory and serologic tests including ANA, anti-ds DNA, anti-cardiolipin antibodies (aCL) and aRP (ELISA) were also carried out. Twenty six (81.2%) patients had one or more NP manifestations. Depression (59.4%), headache (46.9%) and cognitive dysfunction (37.5%) were the commonest NPSLE syndromes. Other less commonly detected manifestations included seizures, anxiety, acute confusional state, stroke, and psychosis. aRP was positive in seven (21.9%) patients, all of whom had one or more NPSLE syndromes. Patients with psychiatric manifestations in general and mood disorders in particular had significantly higher mean titers of aRP than patients without these disorders (p < 0.05). aRP were found to be significantly associated with a younger age at the onset of SLE, with more severe articular manifestations and with the presence but not the severity of depression. aRP were highly specific for NPSLE and depression, and they were highly sensitive for psychosis. Neuropsychiatric manifestations are found in 81.2% of unselected Egyptian SLE patients. The presence of aRP antibodies positively predicts patients with psychiatric manifestations in general and mood disorders in particular, for which aRP is specific, but not sensitive. However, aRP is sensitive for psychosis, so that its absence in patients with SLE may help exclude Lupus psychosis.

Two multidimensional health status instruments of rheumatic diseases, the Dutch-AIMS2 and the IRGL (Impact of Rheumatic diseases on General health and Lifestyle), were compared in a sample of 284 rheumatoid arthritis patients with regard to their measurement properties and usefulness for research purposes. Both questionnaires showed an excellent reliability (Cronbach's alpha), and were highly comparable with regard to their construct and convergent validity. Second-order factor analysis confirmed the physical, psychological and social health dimensions for both questionnaires. The comparability between the instruments was established by high intercorrelations between the physical and psychological health dimensions. Sufficient convergent validity was indicated by the strong correlations between the physical functioning scales and clinical and laboratory measures. The main differences between both questionnaires relate to their length and emphasis on health aspects. The Dutch-AIMS2 is characterized by a more extensive assessment of the physical dimension and the additional measurement of general health aspects. The shorter IRGL exclusively assesses the main health dimensions with a more comprehensive measurement of the psychological and social dimensions. The instrument that reflects the subject in question most adequately should be chosen.

Psoriatic arthritis was described as a distinct rheumatic disease in the 1960s, and subsequently grouped among the spondyloarthropathies. Recently, other rheumatic manifestations of psoriasis, such as enthesopathy and osteoperiostitis, were recognized. This study attempts to examine the rheumatological and radiological manifestations of Psoriasis and their association with skin and nail disease. Eighty-one psoriatic outpatients were interviewed consecutively during 6 months. Questionnaires and indices were carried out to assess the extent and severity of skin and nail involvement, as well as the activity and severity of peripheral and axial rheumatic manifestations. Radiological examination of the hands, feet, spine and pelvis was also done for all patients. Fifty-nine psoriatic outpatients (73%) had rheumatic manifestations clinically and/or radiologically (Psoriatic arthropathy "PsA"). Clinical peripheral arthritis was found in 14 (23.7%) of the patients with PsA, being oligoarticular in 11, polyarticular in two, and exclusively of the distal interphalangeal (DIP) joints in one patient. Sacroiliitis and/or spondylitis were found in 38 (64.4%), enthesopathy in 36 (61%), dactylitis in two (3.3%), radiological DIP involvement in 24 (40.6%), and radiological osteoperiostitis in 49 (83%) of patients with PsA. Most PsA patients had more than one rheumatic manifestation, while four patients (6.7%) had isolated enthesopathy without any other rheumatic manifestations. Subungual hyperkeratosis of the nails was significantly correlated with PsA (p<0.05), as well as with clinical arthritis, enthesopathy, and DIP involvement (p<0.01), while other types of skin and nail lesions were correlated with selected rheumatic manifestations. The performance of existing criteria for PsA was poor, as individual sets favored either sensitivity or specificity. Psoriatic arthropathy (PsA), occurring in about three-quarters of hospital outpatients with psoriasis, is more common than previously thought. More sensitive and specific criteria for the diagnosis and classification of PsA need to be developed, taking into account the recently described clinical and radiological manifestations.
