Bone density in Moroccan women with systemic scleroderma and its relationships with disease-related parameters and vitamin D status

In this case-control study, our first aim was to evaluate the bone mineral density (BMD) in women with systemic sclerosis (SSc) and its correlates. Secondarily, we aimed to evaluate 25-hydroxyvitamin D3 status and its relationships with disease parameters and BMD. Sixty patients with SSc and 60 age-and gender-matched controls were included in the absence of confounding factors that interfere with bone metabolism. Body mass index, menopausal status, familial history of osteoporosis and/or fractures; personal fracture history; exercise activity and laboratory parameters of bone metabolism were assessed in patients and controls. BMD was measured by using a dual-energy X-ray absorptiometry in lumbar spine (L1-L4) and femoral neck. The 25-hydroxyvitamin D3 was measured in a subgroup of 30 patients and in a subgroup of 30 matched controls. Systemic manifestations of SSc, biological inflammatory parameters, functional disability (scleroderma health assessment questionnaire (S-HAQ)) and immunological status of disease were collected in patients' group. The mean age of patients was 49.44?±?13.07?years versus 49.55?±?12.11 in controls. The mean disease duration was 9.63?±?5.9?years. SSc patients had a significantly earlier age and longer duration of menopause than controls (P?=?0.003). Phosphocalcic metabolism parameters were within normal ranges in both groups. BMD was significantly lower in SSc patients than in controls both in lumbar spine (-2.97?±?0.25 in patients vs. 0.46?±?0.11 in controls) and femoral neck (-1.93?±?0.32 in patients vs. -0.81?±?0.69 in controls) (P?相似文献   

Paraneoplastic rheumatic syndromes: report of eight cases and review of literature

Malignant neoplasms are associated with a wide variety of paraneoplastic rheumatological syndromes. The paraneoplastic nature should be based on specific criteria. We report a series of eight cases of paraneoplastic rheumatic syndromes revealing an underlying neoplasia. Our series consists of six men and two women, with a mean age of 46.1 (20-69?years). The first case is a hypertrophic osteoarthropathy of Pierre Marie that occurred in a 20-year-old man 1?month after treatment for his nasopharyngeal carcinoma; the paraclinical examinations showed lung and bone metastasis. The second case is that of a bilateral shoulder-hand syndrome revealing an invasive squamous cell carcinoma of the cervix in a 63-year-old woman. The third case involved a 69-year-old patient who had surgery 2?years ago for prostate adenocarcinoma and presented with polymyalgia rheumatica revealing bone metastasis. We also report two cases of leukemia in adults revealed by polyarthritis. The sixth observation is that of a paraneoplastic scleroderma that occurred concomitantly with prostate cancer. The seventh case of an acute arthritis showed a B lymphoma. The eighth case is that of a 52-year-old patient who presented with inflammatory arthralgias, and digital clubbing revealing a squamous cell carcinoma of the skin. Paraneoplastic rheumatism remains a rare event, but knowledge of it is essential for early diagnosis of underlying cancer.     

Rheumatoid factor and antibodies against citrullinated peptides in Moroccan patients with rheumatoid arthritis: association with disease parameters and quality of life

We aimed to evaluate the immunological status and its relationships with disease-related parameters of activity, severity and quality of life in Moroccan patients with rheumatoid arthritis (RA). Two hundred forty-five consecutive patients with RA were recruited. The following data were collected: demographic characteristics, disease duration (years), disease activity (evaluated by the disease activity score, DAS28), structural damage (evaluated by Sharp's method as modified by van der Heijde), functional disability (assessed by using the Moroccan version of the Health Assessment Questionnaire, HAQ) and quality of life (by using the Arabic version of the Medical Outcomes Study Short Form 36 Health Survey: the SF-36). Immunological status (rheumatoid factor rate, RF) and antibodies against citrullinated peptides rate (ACPAs) by the Elisa method were examined. ACPAs were detected in 75.1% of patients with a mean rate of 79.2 ± 43.8 UI. RF was detected in 80.8% of patients with a mean rate of 80.1 ± 50.6 UI. Patients with positive RF and ACPAs had higher disease activity, impaired functional ability, severe structural damage, more ocular symptoms and altered aspects of quality of life. In univariate analysis, higher levels of ACPAs were significantly correlated with the age at onset (r = 0.307), disease duration (r = 0.520), disease activity (DAS28) (r = 0.531), Sharp score (r = 0.431), and with the deterioration of all domains of SF-36 (for all p ≤ 0.01). RF levels were correlated with disease duration (r = 0.517), disease activity (r = 0.470), functional disability (r = 0.521), and the alteration of physical domains of SF-36 (for all p ≤ 0.01). In multivariate analysis, the main factors associated to ACPAs and RF levels were functional disability, structural damage and impaired QoL. Furthermore, using the SF-36 scores as dependent variables, the impairment of physical domains and the domain of vitality were significantly associated with ACPA levels while the decrease of the domain of physical function was associated with the level of RF. Our study suggests that the presence and the levels of ACPAs and RF in our RA patients are associated with more active disease, more severe joint damage, worst functional disability and altered aspects of quality of life.     

Comparison of the BASDAI and the miniBASDAI in assessing disease activity in patients with ankylosing spondylitis

The BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) is the most widely used instrument for the assessment of disease activity in ankylosing spondylitis (AS). Objective. The aims to investigate whether the alternative BASDAI, here termed as the miniBASDAI [(Question (Q) 1 fatigue + Q2 spinal pain) + mean of (Q5 strength morning stiffness + Q6 duration morning stiffness)] / 3], measures disease activity more accurately in the subgroup of AS patients without peripheral manifestations. One hundred and ten patients were included in this cross-sectional study according to the modified New York criteria for AS. Clinical and biological parameters were evaluated. The disease activity was evaluated by the BASDAI. We calculated the miniBASDAI by omitting both the peripheral joints and the enthesitis questions: questions 3 and 4. Patients were dichotomized into a “P+” group if peripheral manifestations were present (at least arthritis or enthesitis) and a “P−” group, the subgroup without peripheral involvement (with either arthritis or enthesitis). Correlation of the BASDAI and miniBASDAI with other disease parameters were examined with the Spearman's rank correlation analysis. One hundred and ten patients were recruited. The percentage of patients with pure axial disease manifestation without peripheral involvement “P − group” was 42.7%. We found a similarly good correlation of the miniBASDAI with patient global, physician on disease activity, BASFI, ESR and CRP if compared to the correlation of the original BASDAI with these disease parameters, also in the group without peripheral involvement. Our study suggests that the BASDAI remains valid in assessing disease activity in AS patients with and without peripheral manifestations.     

Influence of parity on bone mineral density and peripheral fracture risk in Moroccan postmenopausal women

The aims of the study were to determine: (1) the relationship between parity and bone mineral density (BMD); (2) the relationship between parity and osteoporotic peripheral fractures.

Material and methods

The group studied included 730 postmenopausal women. Patients were separated into four groups according to the number of fullterm pregnancies, group 1: nulliparae, group 2: one to three pregnancies, group 3: four to five pregnancies, and group 4: six and more pregnancies. Additionally, patients were separated into three groups according to their ages, as <50 years, 50–59 years and ≥60 years.

Results

The median parity was 4 [0–20]. All the patients with parity greater than six had spine and hip BMD values significantly lower than values in the other groups (p < 0.001). After adjustment for age and body mass index (BMI), decreased lumbar and total hip BMD were still associated to increased parity (analysis of covariance (ANCOVA), p = 0.04 and 0.023, respectively). The relation between parity and lumbar BMD was highly significant among women aged <50 years (age-adjusted p = 0.022), while there was no parity-spine BMD association in the other age groups. The relation between parity and hip BMD was seen only in the group 50–59 years (age-adjusted p = 0.042). A positive history for peripheral fractures was present in 170 (23%) patients. There was relationship between parity and peripheral fractures neither in the whole population nor in the sub-groups according to age.

Discussion

The present study suggests that the BMD of the spine and hip decreases with an increasing number of pregnancies, and this situation shows variations in different age groups. However, there was no correlation between parity level and peripheral fractures.     

Renal hydatid cyst: A case report

Hydatid disease is a parasitic infection commonly involving the liver, less frequently the lungs, and rarely the kidneys. Reports on renal hydatid disease are limited in literature. In this case study, we share a case of a 37-year-old female who presented with a 3-month history of left flank pain and following further evaluation with laboratory testing and radiological imaging was revealed to be a case of renal hydatid disease. The patient was successfully managed surgically with left total nephrectomy. The study will focus on the findings of renal hydatid disease in radiological imaging modalities.     

Lead-related gout. A case report

Gout secondary to lead-induced nephropathy is a long-term complication of occupational lead exposure. We report a case of this now-rare condition. The patient was a 63-year-old man who had been a miner from 1950 to 1970. Thirty years after cessation of his exposure to lead, he experienced onset of inflammatory symmetric polyarthritis with joint deformities. Hyperuricemia, moderately severe renal failure, and tubular acidosis were found, indicating gouty polyarthritis. Blood lead levels were high, establishing that the cause was lead poisoning. EDTA chelation therapy was effective. Lead poisoning is frequently under-recognized because the clinical manifestations are often minimal and the diagnosis difficult to establish. We suggest that lead bound to bone may result in continued exposure to lead after cessation of industrial or environmental exposure. Chelating agents are valuable for the diagnosis and can ensure a full recovery.
