We report a case of systemic lupus erythematosus (SLE) in a young woman who presented a serious encephalopathy with respiratory distress and coma, after arbitrary interruption of oral corticosteroid therapy when her first pregnancy ended in abortion. The patient showed rapid improvement on methylprednisolone pulse therapy. The case suggests the utility of such a therapy in severe, non focal, CNS complications of SLE.

Synchronous respiration during mechanical ventilation of preterm neonates with acute respiratory distress is extremely beneficial as it improves oxygenation and is associated with a very low incidence of pneumothorax. We have assessed which form of ventilation: patient triggered ventilation (PTV) or high frequency positive pressure ventilation (HFPPV) is most successful in provoking this beneficial respiratory interaction, synchrony. Preterm infants of less than 4 hours of age and gestational age greater than or equal to 27 weeks were entered into a randomised controlled trial. Thirteen patients received PTV, median gestational age 30 weeks (range 27-36) and 36 HFPPV, median gestational age, 29 weeks (range 27-40). HFPPV was delivered by Sechrist ventilators at rates between 61 and 120 breaths/minute. Patient triggered ventilation was delivered by an SLE ventilator and an airway pressure trigger was used. Inflation times during PTV were between 0.2 and 0.45 seconds. HFPPV provoked synchrony which persisted until extubation in 25 patients, but PTV provoked persistent synchrony only in four patients (p less than 0.05). No infant developed a pneumothorax. Eleven of 36 patients became asynchronous on HFPPV and 5 of 13 on PTV. In addition, four patients on PTV developed recurrent apnoea with deteriorating blood gases. Thus, 11 of 36 patients on HFPPV and 9 of 13 on PTV required transfer to conventional ventilation (p less than 0.05). Transfer occurred at a median of 30 hours (range 6-84) on HFPPV and 1 hour (range 1-25) on PTV, p less than 0.01. Infants who required transfer from the randomised mode of ventilation required a longer period of intubation (median 174 hours, range 30-2928) compared to 38 hours (range 1.5-456) for successful cases, regardless of randomisation (p less than 0.01). This study demonstrates PTV is significantly less successful in promoting synchrony than HFPPV. We therefore conclude HFPPV is a more useful form of respiratory support than PTV for preterm infants with acute respiratory distress.

The usefulness of airway pressure triggered ventilation for the preterm newborn has been assessed using a new patient triggered valveless ventilator, the SLE 2000 infant ventilator (SLE 2000). This ventilator performs well at fast rates with no inadvertent positive end expiratory pressure (PEEP) even at rates of 150 breaths per minute (bpm). The ventilator is triggered by a change in airway pressure equal to or exceeding 0.5 cmH2O. If the infant fails to achieve the change in airway pressure which will trigger the ventilator the infant is ventilated at the back-up rate which is predetermined in conventional mode prior to commencing PTV. Infants were ventilated for one hour on a conventional neonatal ventilator, then for one hour on the SLE 2000 in conventional mode without changing the ventilator settings and finally for one hour on the SLE 2000 in patient triggered mode. Arterial blood gases were checked at the end of each hour. During patient triggered ventilation (PTV) the peak pressure, inspiratory time and inspired oxygen concentration were the same as those used during conventional mode. Simultaneous recordings were made of flow, volume, ventilator and oesophageal pressure change, from this recording the trigger delay during PTV was calculated. The trigger delay, being the time lag from the start of spontaneous inspiration, indicated by the negative deflection in the oesophageal pressure trace, and the onset of the ventilator breath. Thirteen infants were included in the study, median gestational age 32 weeks (range 25-35) and birthweight 1640 g (range 838-3038). All were being ventilated for respiratory distress syndrome (RDS) and were 4 days of age.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a patient who presented with an association between propylthiouracil treatment and recurrent episodes of an adult respiratory distress-like syndrome (ARDS). The bouts of ARDS were associated with a generalized reaction suggestive of systemic lupus erythematosus (SLE), responsive to corticosteroid therapy.

Two cases of pathologically confirmed miliary pulmonary tuberculosis complicated with ARDS were presented. Both had systemic lupus erythematous and used maintenance dose of corticosteroid. Case one developed respiratory distress and severe hypoxemia one day postpartum and chest radiograph revealed nodular and miliary infiltrations and pleural effusion. The patient was intubated and placed on a volume-cycled ventilator. A FIO2 of 70% and a PEEP of 0.98 kPa were required to maintain the oxygen tension at 6.95 kPa. The effective compliance of the lung decreased progressively and the patient died 5 days later. Autopsy revealed disseminated tuberculosis extensively involving the lungs, the liver and kidney. The alveoli were filled with edematous fluid with formation of hyaline membranes and micro-atelectasis. Case two developed respiratory distress and pulmonary edema at the third month of pregnancy. Cardiopulmonary arrest occurred when trying to intubate the patient. Postmortem needle puncture of the lungs and liver revealed charges comparable with tuberculosis and ARDS. In considering the relatively high incidence of pulmonary tuberculosis in China, the percentage of miliary tuberculosis as a potential cause of ARDS might not be very low. It is important to maintain a high index of suspicion for this treatable precipitating disorder and initial appropriate therapy early enough in patients with ARDS.

Antepartum fetal monitoring was initiated at 19 to 26 weeks' gestation in 15 pregnancies: six (five with systemic lupus erythematosus, one with circulating anticoagulant) with a complicated antepartum course (group 1); three, all systemic lupus erythematosus, with a normal antepartum course (group 2); and six normal control pregnancies (group 3). Group 1 all exhibited nonperiodic fetal heart rate decelerations, without the classical appearance of early, late, or variable decelerations, and four of the six had fetal bradycardia. In three group 1 cases, there was no active intervention because of early gestational age, and fetal death occurred at 23, 27, and 27 weeks, respectively. The other three patients in group 1 received betamethasone and were delivered by cesarean section at 28 to 30 weeks. There were no cases of respiratory distress syndrome or neonatal death. Five of the six infants in group 1 were small for gestational age. The nonperiodic fetal heart rate decelerations were absent in both groups 2 and 3 who all had normal fetal outcomes at term. The abnormal finding of women with nonperiodic fetal heart rate decelerations at 20 to 28 weeks may detect the fetus at risk for intrauterine death in pregnancies complicated by systemic lupus erythematosus or circulating anticoagulant. Continued surveillance, steroid induction of lung maturity, and delivery should be considered in these cases.

The patient, a 30 year-old Caucasian female with a 6-year history of systemic lupus erythematosus was suspected of having pulmonary hypertension following chest X-Ray and routine echocardiography. Whilst awaiting further cardiological investigations she developed acute respiratory distress accompanied by gross signs of cor pulmonale and died despite full intropic and ventilatory support, in addition to intravenous "Pulse" methyl prednisolone. Postmortem findings showed typical features of the adult respiratory distress syndrome ('ARDS') but minimal vascular changes attributable to the pulmonary hypertension. The 'ARDS' was presumably associated with an acute 'flare' of the lupus.

We describe 12 patients with systemic lupus erythematosus (SLE) who developed massive pulmonary hemorrhage with very active disease. Other causes of pulmonary bleeding were excluded. Eleven of the 12 patients died, but only 4 had hemoptysis. Massive pulmonary hemorrhage should be suspected, even in the absence of hemoptysis, in severely ill patients with lupus who develop acute respiratory distress with bilateral pulmonary infiltrates and a drop in hemoglobin of 3 or more g/dl. Because of the deadly nature of this complication of SLE, when it is suspected, intensive corticosteroid and immunosuppressive treatment should be instituted.

Laryngeal complications in systemic lupus erythematosus (SLE) are rarely described. They range from hoarseness to life-threatening respiratory distress. To our knowledge, previous reports describe laryngeal involvement with SLE occurring only during periods of active disease. We saw a patient with inactive SLE in whom hoarseness and exertional dyspnea developed as a result of arytenoiditis and vocal cord paresis during steroid tapering. The condition responded dramatically to readjustment of her steroid dosage. Involvement of the larynx with SLE is a potentially life-threatening complication and may occur in patients with either active or inactive disease. It is an indication for close observation and steroid therapy in patients with SLE.

The case reported concerned a patient 44 years old, affected by a systemic lupus erythematosus for 18 years and admitted for an acute respiratory distress due to a bronchopulmonary infection. After this episode an interstitial chronic lung disease is diagnosed (reticulonodular pattern on the chest X-ray, functional restrictive syndrome). The study of the transbronchial lung biopsy by electron microscopy revealed interstitial electron dense deposits. This observation focussed on the interest of this technic of morphological study mainly in chronic lung interstitial diseases.
