Introduction:Pulmonary arterial hypertension (PAH) is a serious and often fatal complication of systemic lupus erythematosus (SLE). Because the diagnosis of PAH often is made years after symptom onset, early diagnostic strategies are essential. Doppler echocardiography currently is considered the noninvasive screening test of choice for evaluating pulmonary hypertension.Aim:Screening for asymptomatic pulmonary hypertension in systemic lupus erythematosus patients using Doppler echocardiography, and correlating it with inflammatory parameters of the disease.Patients and methods:Doppler echocardiography was performed in 74 patients with systemic lupus erythematosus over one year (66 adult and 8 juvenile), adult SLE included 57 patients with adult-onset and 9 patients with childhood-onset. Pulmonary hypertension was diagnosed if the peak systolic pressure gradient at the tricuspid valve was more than 30 mmHg. All patients were subjected to full history taking, rheumatological examination, laboratory studies and chest x-ray.Results:In seventy four SLE patients, the pulmonary hypertension was detected in 8 patients (10.8%), 7 adult-onset SLE patients (aged from 19 to 30 years) and 1 juvenile SLE (aged 12 years). The range of pulmonary artery systolic pressure was 34–61.2 mmHg (43.19 ± 9.28). No significant differences between patients with and those without pulmonary hypertension as regard clinical features. Significantly higher frequencies of rheumatoid factor and anti-cardiolipin antibodies were found in patients with pulmonary hypertension versus those without (P = 0.02, P = 0.008 respectively). Positive rheumatoid factor and ACL were significantly associated with occurrence of PAH in SLE (P = 0.007, P = 0.006 respectively). No significant correlations were found between pulmonary artery pressure, disease duration, SLE Disease Activity Index (SLEDAI), ESR, and anti-ds DNA.Conclusion:Patients with SLE have an increased risk of pulmonary arterial hypertension. Echocardiography should be used as a screening tool in patients at high risk for development of pulmonary hypertension. Positive anti-cardiolipin antibodies and rheumatoid factor were significant predictors of pulmonary hypertension in our study.

AimTo determine whether early clinical, laboratory and musculoskeletal ultrasound (MSUS) characteristics can be used as early detectors of juvenile idiopathic arthritis.Patients and methodsForty (40) patients with juvenile idiopathic arthritis (JIA) diagnosed according to the ILAR criteria [1] and 20 healthy control children. All patients were subjected to the following assessment at base line and at follow up after 6 months: Clinical evaluation, MSUS examination and laboratory evaluation.ResultsOf the 40 patients, 6 patients (15%) had systemic onset subtype, 8 (20%) oligoarticular extended, 9 (22.5%) oligoarticular persistent, 5 (12.5%) polyarticular rheumatoid factor (RF) +ve, 6 (15%) polyarticular RF −ve, 5 (12.5%) enthesitis related subtype and only one patient (2.5%) had psoriatic JIA. MSUS detected more synovitis than clinical examination (subclinical synovitis) both at base line and at follow up. MSUS is highly sensitive for early detection of joint involvement in JIA when compared to physical examination. Significant decrease in the mean cartilage thickness of the patients measured at follow up as compared to measures at base line.ConclusionMSUS is highly sensitive for early detection of joint involvement in JIA when compared to physical examination
