Özet

Postpartum psychosis is an acute illness of multifactorial origin and is considered

a psychiatric emergency. With an estimated global prevalence of 0.089 to 2.6 per

1000 births, postpartum psychosis classifies as an illness with a low incidence

rate. However, it carries the potential for serious medical and social consequences,

including the risk of suicide and filicide, if not promptly detected and

treated. The clinical picture of postpartum psychosis includes a wide variety of

rapid-onset psychotic symptoms such as hallucinations and delusions, strange

behavior, confusion, delirium-like disorganization and catatonia [1].In this

article we present a case of postpartum psychosis presenting with catatonia and

responsive to thiamine treatment.

A 30-year-old female patient who was 6 weeks postpartum with no previous

history of psychiatric illness and no significant family history admitted to psychiatry

clinic with loss of apetite, decreased speech amount, psychomotor

retardation, auditory hallucinations and thought disorder (‘’this is not my baby,

my marriage is fake.’’). At her physical examination she had immobility, mutism,

staring, posturing, echopraxia, rigidity, withdrawal, autonomic obedience and

proximal muscle weakness in upper and lower limbs. The Bush-Francis Catatonia

rating scale was 14 points. Additionally in her psychiatric evaluation she had

short-term memory impairment, confusion and confabulation. Initially, lorazepam

was added 7,5 mg/day to treatment for her catatonia, rapid response to

lorazepam was observed. However, no remarkable response was observed to

olanzapine 10 mg/day, her psychotic symptoms and cognitive impairment

remained. Lumbar puncture, brain MRI, PET-MRI, and EEG investigations were

performed for differential diagnosis. Any abnormal finding was not observed

except slightly high protein level in cerebrospinal fluid (CSF). Also screening of

antibodies for autoimmune etiology in CSF and serum resulted negative.

Consideration of postpartum period, poor nutritional intake before hospital

admission due to the catatonic symptoms, cognitive impairment and high serum

lactate level (31,73 mg/dL) and pyruvate level (1,51 mg/dL) with slight acidosis

(pH:7,301), empirical intravenous (IV) thiamine 1500 mg/day infusion was added to treatment for 8 days. During the IV thiamine administrations, her shortterm

memory impairment, confusion and confabulation significantly improved at

fourth day, serum lactate and pyruvate levels turned the normal level at the end

of admissions. With 5 mg/day olanzapine and 500 mg/day oral thiamine treatment,

her psychotic symptoms and proximal muscle weakness in upper and lower

limbs ameliorated. The patient was discharged to be followed up in outpatient

clinic.

When evaluating for thiamine deficiency, the typical history may include poor

nutritional intake, excessive alcohol intake, or the patient belonging to the special

populations (pregnant women, recipients of bariatric surgery, anyone with

poor overall nutritional status, etc.) [2].The present patient indicates that the

possibility of thiamine deficiency should be considered in cases of psychosis and

cognitive impairment especially in peripartum period without classical neurological

disturbance (nystagmus, opthalmoplegia, paresthesias etc.) and high-intensity

T2 MRI lesions [3].
