systemic lupus - Nursing Case Study

Pathophysiology

• Primary mechanism: Autoantibody production—Systemic lupus erythematosus (SLE) is characterized by the loss of immune tolerance, leading to the production of autoantibodies, particularly anti-nuclear antibodies (ANAs) and anti-double-stranded DNA antibodies. These autoantibodies form immune complexes that deposit in tissues, causing inflammation and damage.

• Secondary mechanism: Complement system activation—Immune complex deposition activates the complement cascade, enhancing inflammation and tissue injury. This exacerbates damage in various organs, especially the kidneys, skin, and joints, contributing to the chronicity and severity of SLE.

• Key complication: Lupus nephritis—The deposition of immune complexes in the renal glomeruli leads to inflammation and scarring, impairing kidney function. This can progress to end-stage renal disease, necessitating dialysis or transplantation, highlighting the critical importance of early diagnosis and management in SLE patients.

Section 1

During the initial assessment, the patient's clinical presentation suggested a severe exacerbation of her systemic lupus erythematosus. Her vital signs indicated hemodynamic instability and respiratory distress, with hypotension, tachycardia, tachypnea, and hypoxemia. Physical examination revealed significant bilateral pitting edema in the lower extremities, a malar rash typical of lupus, and bilateral coarse crackles upon lung auscultation, suggesting pulmonary involvement. Cardiac assessment detected a pericardial friction rub, consistent with her history of recurrent pericarditis.

Laboratory results showed a marked decline in renal function, with elevated serum creatinine at 3.4 mg/dL and a glomerular filtration rate (GFR) of 22 mL/min/1.73 m², indicating worsening lupus nephritis. Urinalysis revealed significant proteinuria and hematuria, further confirming renal impairment. Blood tests indicated severe anemia with a hemoglobin level of 8.5 g/dL, leukopenia, and thrombocytopenia, consistent with active disease flare and possible bone marrow suppression. Anti-double-stranded DNA antibody levels were elevated, and complement levels (C3 and C4) were markedly decreased, reflecting active immune complex formation and consumption.

Given the complexity of her condition, the interdisciplinary team prioritized stabilizing her hemodynamics and addressing her respiratory distress. High-flow oxygen therapy was initiated, and intravenous fluids were cautiously administered, balancing the risk of exacerbating her pulmonary status. The rheumatology consultation recommended intensifying her immunosuppressive therapy, considering the addition of intravenous cyclophosphamide to manage her severe lupus nephritis and systemic involvement. This case highlights the need for advanced clinical judgment to manage the multifaceted challenges posed by severe SLE complications, necessitating close monitoring and adjustment of therapeutic strategies.

Section 2

Following the initial interventions, the patient demonstrated a partial response to the high-flow oxygen therapy, with a slight improvement in her oxygen saturation levels; however, her respiratory distress persisted. Despite cautious fluid resuscitation, her hemodynamic status remained tenuous, with persistent hypotension and tachycardia, suggesting inadequate perfusion. A repeat echocardiogram was performed, revealing a moderate pericardial effusion with signs of early cardiac tamponade, necessitating an urgent pericardiocentesis to relieve pressure on the heart and stabilize her cardiovascular status.

In parallel, the patient's renal function continued to deteriorate rapidly, as evidenced by an increase in serum creatinine to 4.1 mg/dL and a GFR decline to 18 mL/min/1.73 m². The nephrology team was consulted, and continuous renal replacement therapy (CRRT) was initiated to manage her acute kidney injury and severe electrolyte imbalances, including hyperkalemia with a serum potassium level of 6.2 mmol/L, posing a risk for life-threatening cardiac arrhythmias. Given her worsening anemia, a transfusion of packed red blood cells was also administered to improve her oxygen-carrying capacity, with careful monitoring to avoid fluid overload.

Despite these aggressive interventions, new complications arose as the patient developed signs of neuropsychiatric lupus (NPSLE), presenting with confusion and disorientation. A neurologic assessment, including a brain MRI, revealed small, scattered ischemic lesions consistent with vasculitis. This new development required a further escalation of her immunosuppressive regimen, with the addition of high-dose corticosteroids to control the inflammation. The interdisciplinary team faced the challenge of balancing the potential benefits and risks of intensified immunosuppression, considering her precarious condition and the risk of opportunistic infections. The patient's complex clinical trajectory underscored the need for vigilant monitoring and dynamic adjustment of her treatment plan to navigate the multifaceted challenges posed by severe systemic lupus erythematosus.

Section 3

As the interdisciplinary team continued to manage the patient's complex condition, they noted a concerning change in her neurologic status. Over the course of several hours, the patient's confusion and disorientation progressed to a more profound encephalopathy. She became increasingly somnolent and difficult to arouse, with a marked decline in her Glasgow Coma Scale (GCS) score to 9, indicating a significant alteration in her level of consciousness. Vital signs indicated ongoing instability: blood pressure remained low at 85/50 mmHg despite vasopressor support, heart rate was persistently elevated at 125 beats per minute, and her temperature spiked to 38.5°C, raising the suspicion of an infectious process.

In response to these alarming developments, the team prioritized further diagnostic evaluation. A lumbar puncture was performed to rule out central nervous system infection, with cerebrospinal fluid analysis showing pleocytosis, elevated protein levels, and the presence of anti-neuronal antibodies, supporting the diagnosis of NPSLE exacerbation rather than infection. Concurrently, a full infectious workup, including blood cultures and a complete septic screen, was initiated due to the high risk of opportunistic infections secondary to her intensified immunosuppressive therapy. Despite negative initial culture results, broad-spectrum antibiotics were commenced preemptively.

The patient's renal function continued to decline, with serum creatinine rising to 5.2 mg/dL, necessitating ongoing CRRT. Electrolyte imbalances worsened, with persistent hyperkalemia and new-onset hyponatremia. The nephrology team adjusted her CRRT settings to address these electrolyte disturbances more aggressively. This multifaceted clinical picture demanded constant reevaluation and adjustment of the treatment plan, highlighting the need for advanced critical thinking to balance the benefits of immunosuppression against the risks of infection and worsening organ dysfunction. The team remained vigilant, prepared to tackle further complications as the patient's journey continued to unfold.

Section 4

As the interdisciplinary team continued to monitor the patient’s condition, they noted a further deterioration in her respiratory status, indicating a new complication. The patient developed increasing respiratory distress, characterized by tachypnea with a respiratory rate climbing to 35 breaths per minute and a notable decrease in oxygen saturation to 87% on 4 liters of nasal cannula oxygen. Auscultation revealed diffuse bilateral crackles, suggestive of pulmonary involvement. A prompt arterial blood gas analysis showed a mixed respiratory and metabolic acidosis, with a pH of 7.25, PaCO2 of 55 mmHg, and HCO3 of 18 mEq/L, highlighting the severity of her respiratory compromise and metabolic derangement.

In response, the team escalated her respiratory support, transitioning her to high-flow nasal cannula oxygen therapy in an attempt to stabilize her oxygenation. Concurrently, a chest X-ray was performed, revealing bilateral infiltrates consistent with pulmonary edema or potential acute lupus pneumonitis, a known pulmonary complication of systemic lupus erythematosus. Given her worsening renal function and fluid overload, the pulmonology and nephrology teams collaboratively decided to initiate diuretic therapy cautiously, balancing the need to reduce pulmonary congestion with the risk of further compromising her renal perfusion.

Despite these interventions, the patient's condition remained precarious, necessitating an urgent multidisciplinary discussion to consider advanced respiratory support options such as non-invasive ventilation or even mechanical ventilation if her respiratory status continued to decline. This complex scenario required the team to exercise advanced clinical reasoning to navigate the delicate balance between aggressive treatment of her lupus exacerbation, careful management of her organ dysfunction, and the prevention of additional complications, all while keeping the patient’s overall prognosis and quality of life in mind.

Section 5

As the interdisciplinary team continued their vigilant monitoring, the patient's condition took another critical turn. Despite the escalation to high-flow nasal cannula oxygen therapy, her respiratory distress intensified, and she began exhibiting signs of acute respiratory failure. Her respiratory rate climbed further to 40 breaths per minute, with retractions and nasal flaring becoming more pronounced. Her oxygen saturation dropped alarmingly to 82%, despite the increased oxygen support. This prompted an urgent decision to transition her to non-invasive positive pressure ventilation (NIPPV) to avert further deterioration.

The team ordered a repeat arterial blood gas analysis, which revealed an exacerbation of her mixed acidosis: the pH had declined to 7.20, PaCO2 increased to 60 mmHg, and HCO3 remained critically low at 16 mEq/L, indicating ongoing severe metabolic and respiratory compromise. Additionally, the latest kidney function tests showed a further decrease in glomerular filtration rate (GFR), now at 20 mL/min/1.73 m², signifying acute kidney injury progression. The nephrology team raised concerns about potential lupus nephritis exacerbation, further complicating the management of her fluid status and adding urgency to the decision-making process regarding renal replacement therapy.

In light of these developments, the team engaged in a high-stakes discussion to evaluate the feasibility of initiating hemodialysis to manage her worsening renal function and metabolic acidosis while considering her fragile respiratory state. The opportunity to implement continuous renal replacement therapy (CRRT) was also explored, given its more gentle fluid removal capability, which might better suit her delicate hemodynamic status. This pivotal point in the patient's care required the team to weigh the risks and benefits of each intervention meticulously, factoring in the potential for further complications against the pressing need to stabilize her condition.
