Catatonia can occur in patients diagnosed with schizophrenia and bipolar disorder and malignant catatonia is life-threatening . Anti-psychotic medications should be discontinued during acute phase of catatonia. Anti-psychotic discontinuation in catatonia is a challenge in patients maintained on long-acting injectable antipsychotics because of the extended release. Because of the extended release, malignant catatonia and neuroleptic malignant syndrome (NMS) could last several weeks . We present a case of malignant catatonia developed in a patient with history of schizophrenia and developmental delay. Symptoms lasted several weeks as he was recently administered long acting injectable antipsychotic medication, requiring high dose Bromocriptine treatment.
2. Case Report
Patient is a 27year old male with history of schizophrenia and developmental delay and he was admitted to an outside state inpatient psychiatry facility. From there, he was emergently transferred to our multi-specialty center for work up and treatment of fever (Table 1). Patient was in the Emergency room for 3 days. Chest x ray showed right basilar opacity. Vital signs: BP 136/81 | Pulse 101 | Temp 100.4 °F (38 °C) | Resp 16 | SpO2 97%. He was started on vancomycin 1,500 mg in dextrose 5% 250 ml IVPB for pneumonia. Computerized tomography (CT) showed pulmonary emboli (PE). He received enoxaparin injection. Transthoracic echocardiogram was (TTE) done with no evidence of right ventricular dysfunction.
He was admitted to outside state inpatient psychiatry facility for 6 weeks before transfer to our facility. Per collateral history, patient was started on risperidone and valproic acid for behavioral changes, aggression and psychosis. Patient began refusing medications. 12 days before transfer to our facility, he received Paliperidone Palmitate 234 mg IM and 156 mg IM 1 week after the first dose. Risperidone 2 mg PO qhs and oxcarbazepine 600 mg BID for mood symptoms were the other medications given at outside state inpatient psychiatry facility. It is not clear if oral supplementation or challenge prior to initiation of paliperidone palmitate treatment was conducted. As mentioned above, risperidone was one of his medication listed in medication list (Prior to admission list). Prior responses or adverse events with other psychiatric medications including antipsychotics was not known.
Patient was diagnosed with developmental delay at age 5. First inpatient psychiatric hospitalization was at age 18 after displaying negative symptoms (isolation, flat affect) of psychosis, and he was started on quetiapine for schizophrenia at that time. Per collateral history, patient frequently discontinued medications. He was hospitalized at outside state inpatient psychiatry facility earlier in the year and he was started on risperidone and valproic acid, patient self-discontinued both medications. Upon discharge, he was living with his mother, his medication intake history were unknown, he started to become more aggressive and police took him to outside state inpatient psychiatry facility for the most recent hospitalization before transfer to our facility.
His recent history of psychiatric medications (ie, duration and course of medications over the previous 3 to six months before admission to outside state inpatient psychiatry facility was unknown.
2.1 Psychiatry Consult on Day 5
Psychiatry was consulted on day 5 for medication adjustment (Table 2). On interview, patient spoke minimally and was often staring straight ahead. He was oriented to person, time, place and date. Given patient's acute change in mental status, moderate upper extremity rigidity, posturing, and staring episodes, there was suspicion current condition may be due to catatonia and psychosis. Lorazepam 1mg BID (twice daily) PO and aripiprazole 5mg PO nightly were given.
Bush-Francis Catatonia Rating Scale (BFS) was administered . BFS exam notable for: immobility and stupor, mutism, staring (fixed non-reactive), posturing, mild to moderate rigidity, resistance (2 out of 3), mild negativisms, global resistance (1 out of 3), notable waxy flexibility (3), some withdrawal (1 out of 3) with the BFS score of 14.
Patient did well after lorazepam by mouth, ate his meal and went to sleep after the lorazepam. Suggesting positive response to lorazepam, lorazepam 1mg IV Q6H was scheduled.
2.2 Aripiprazole 5mg PO Nightly Was Continued for 5 Days (From Day 5 to 10)
2.3 ICU Transfer Day 10
On day 10, he was responsive to most questions and endorsed feeling "OK." Per medical team, patient was more interactive with improved eye contact. Lorazepam 1 mg Intravenous (IV) was continued given progressive improvement. Later that day, patient had a Modified Early Warning Score (MEWS)  of 7. Rapid Response Team was called. His heart rate was in 140s, respiratory rate > 30, Oxygen saturation 93% on room air, and temperature was 102. Psychiatry re-evaluated patient for malignant catatonia, his BFS was 14. Bromocriptine 5 mg PO BID was started for malignant catatonia and aripiprazole was discontinued. Lorazepam was continued.
He was transferred to Medical Intensive care Unit (MICU) as his temperature was 103.1 and HR 137. RR 40, and temperature was 103. Per MICU, diagnosis likely was Neuroleptic Malignant Syndrome (NMS) though NMS can be difficult to distinguish from malignant catatonia. MICU team agreed with Bromocriptine and Lorazepam. BFS score was 18, worsened from score of 14. Bromocriptine was titrated to 10 mg TID. Lorazepam 1 mg IV q6h for catatonia was continued., BFS improved to 10 and he was transferred back to general medical floor. On Day 14, BFS score was 9. VITALS BP 134/78 | Pulse 107 | Temp 100.3 °F (37.9 °C) | Resp 20 | Wt 102.6 kg (226 lb 3.2 oz) | SpO2 97%, CK down trending (666->598)
2.4 Bromocriptine Titration Day 17
He showed clinical improvement in terms of speech and autonomic stability but still had mild-moderate rigidity, waxy flexibility and staring. Anticipating that catatonia symptoms will be on-going as patient received monthly long acting injection, bromocriptine was increased to 15 mg TID. On Day 17, creatinine kinase (CK) was up trending (1000->1250) with increased upper limb rigidity, bromocriptine was increased to 20mg tid and titrated again to 20mg qid. Rigidity and tremor in upper extremities improved, still more pronounced in left>right. He was improving his PO intake and ambulation. Transfer to another hospital for Electro Convulsive Treatment (ECT) was planned as ECT is the best and proven treatment for malignant catatonia. Day 20 VITALSBP 122/81 | Pulse 105 | Temp 97.6 °F (36.4 °C) | Resp 20 | Wt 102.6 kg (226 lb 3.2 oz) | SpO2 95% CK trending down (1251 -->971 -->885)
2.5 Discharge Day 23
On day 22, bromocriptine decrease was attempted, patient exhibited increased rigidity and staring episode and he was diaphoretic. Bromocriptine was increased again to 20mg qid. On day 23, patient was walking without assistance, he was alert and awake, with improving spontaneity of speech. Patient stated that his mood is ok, was happy to be walking around, and hugged and thanked providers. Bromocriptine dose was decreased to 15mg QID. Patient was discharged to area med/psych unit with ECT capability. That center was contacted 2 weeks after the transfer and was reported that patient was discharged home.
Catatonia responds to benzodiazepines and ECT [1,5]. Reports indicate that malignant catatonia overlaps with NMS . Bromocriptine is used for treating NMS [7,8]. It is a dopamine receptor agonist on D2 dopamine receptors . Anti-psychotic medications should be discontinued during acute phase of catatonia. Long-acting injectable antipsychotics could lead to prolonged period of NMS . It is not clear what could have caused catatonia in our patient presented in this case report, multiple factors may have played a role. Catatonia can occur in patients diagnosed with schizophrenia and bipolar disorder. Medical conditions also cause catatonia. Malignant catatonia is life threatening, complications include PE and pneumonia . Patient presented in this case report with schizophrenia and developmental delay was transferred from outside hospital due to fever, leukopenia, and suspected pneumonia. Both PE and pneumonia are complications of catatonia . At the mental health center, patient was administered paliperidone palmitate injection 1 week before admission to our medical center for pneumonia and subsequent PE. Patient received Aripiprazole 5mg PO nightly for 5 days (from day 5 to 10). Patient presented with fever to ER and psychiatry saw patient on day 5. Patient received diagnosis of catatonia and psychosis, lorazepam and aripiprazole were prescribed for catatonia and psychosis. Aripiprazole may have likely added to patient's worsening of catatonic symptoms. Second-generation antipsychotics are associated with NMS .
There are limitations to our case report. The patient was emergently transferred to our multi-specialty center for work up and treatment of fever. It is not clear if oral supplementation or challenge prior to initiation of paliperidone palmitate treatment was conducted, Risperidone was one of his medication mentioned in the list. Prior responses or adverse events with other psychiatric medications including antipsychotics is not known. The main challenge while managing the patient was the extended release of antipsychotic medication from long acting anti-psychotic injection. All long acting anti-psychotic injection exhibits sustained release for days and weeks. During malignant catatonia, anti-psychotics should be avoided.
Pneumonia could lead to acute heart failure . Right ventricular diastolic function in pneumonia is reported  and TTE will be beneficial . RV dynamics were normal for patient per TTE. Patient showed clinical improvement in terms of autonomic stability, CPK and PO intake; but rigidity has been persistent. Anti-psychotic discontinuation in catatonia is a challenge in patients maintained on long-acting injectable antipsychotics because of the extended release. This could be related to the prolonged duration expected in of malignant catatonia caused by depot anti-psyhcotics. Catatonia symptoms was on-going as monthly Paliperidone injection was still in his system. Bromocriptine's half-life is 3.3 hours and frequent dosing is recommended . During initial treatment, Bromocriptine was administered as TID dosing and when the dose was increased to QID dosing, patient showed progress with decrease in catatonic symptoms.
Malignant Catatonia is medical emergency and complications include pneumonia and PE. TTE should be considered to rule out cardiac complications of pneumonia. Anti-psychotic medications should be discontinued during acute phase of catatonia. Anti-psychotic discontinuation in catatonia is a challenge in patients maintained on long-acting injectable antipsychotics because of the extended release. ECT should be considered if available. Patients with depot induced malignant catatonia could require 2-3 weeks of bromocriptine treatment. Because of the shorter half-life, frequent and higher dosing of bromocriptine will be beneficial in malignant catatonia.
