Life-threatening ketoacidosis in a pregnant woman with psychotic disorder

A case report and literature review of olanzapine-associated hyperglycemia with previous history of gestational diabetes

Background

Olanzapine (Zyprexa) package labeling includes a warning for hyperglycemia, stating physicians should consider the risks and benefits when prescribing olanzapine to patients with an established diagnosis of diabetes mellitus or having borderline increased blood glucose levels. A case report of olanzapine-associated hyperglycemia in a patient with a history of gestational diabetes mellitus (GDM) is presented and literature review is discussed.

Case Report

A 33-year-old female with a past medical history of bipolar disorder, cocaine and amphetamine use disorder, hypertension, and GDM was initiated on olanzapine 5 mg PO daily which was subsequently titrated to 25 mg daily. On day 15 of admission, she developed signs and symptoms of hyperglycemia, with blood glucose readings >500 mg/dL. Insulin was initiated, olanzapine was discontinued, and her blood glucose began improving. She was later discharged on ziprasidone 20 mg PO twice daily.

Discussion

There have been several case reports published on olanzapine-induced hyperglycemia. This is the first case report to specifically recognize a history of GDM as a potential risk factor for developing olanzapine-associated hyperglycemia.

Conclusion

Adverse effect profiles and patient-specific risk factors should be considered when selecting appropriate antipsychotic treatment. Olanzapine may not be an ideal medication choice for a person with a history of GDM; however, if olanzapine is indicated, then close blood glucose monitoring is recommended.

Ketoacidosis in a non-diabetic lactating woman: A case report and literature review

We report the case of a 36-year-old woman who developed non-diabetic ketoacidosis following a low carbohydrate diet in order to lose weight while actively breast feeding her newborn. She was admitted in intensive care unit because of severe metabolic acidosis. She rapidly recovered after refeeding process. Lactation ketoacidosis, a special condition that occurs in non-diabetic breastfeeding women, is rare and life-threatening. This report highlights the importance of nutritional education of lactating women in the post-partum period.

Severe and persistent mental illness (SPMI) in pregnancy and breastfeeding: focus on second-generation long acting injectable antipsychotics

Introduction: Pregnant women and fetuses are more likely than ever to be exposed to antipsychotic drugs (APs) during pregnancy and postpartum period. Second-generation APs (SGA) are increasingly used among women in reproductive age. Key outcomes (i.e., congenital malformations, pregnancy and maternal outcomes, neonatal/infant risks, and developmental/long-term outcomes) following the exposure to APs remain limited in number and size and yield of inconsistent findings overall, particularly regarding long-acting injectable AP (LAI-APs) formulations.Areas covered: The review aims at providing a summary of current knowledge on potential risks and safety profile of LAI-APs during pregnancy and breastfeeding, specifically focusing on SGA.Expert opinion: The management of safety and tolerability of long-acting injectable AP (LAI-APs) is far from having solid scientific evidence. In fact, due to ethical reasons, there is a lack of randomized clinical trials that limits the reliability and generalizability of the available data on LAI-APs safety profile during the perinatal period, being limited in the scientific literature only to isolated case reports. Therefore, it seems to be important for the future pathways to perinatal mental health care, providing a network of specialized clinicians and systematically collecting data of pregnant/puerperal women on oral and/or LAI APs-therapy about mother and infant outcomes.

Preoperative prolonged fasting causes severe metabolic acidosis: A case report

RATIONALE

Preoperative prolonged fasting may cause starvation ketoacidosis. Herein, we report of a case of starvation ketoacidosis due to long-term fasting before surgery.

PATIENT CONCERNS

We report of a case of metabolic acidosis due to prolonged fasting in a previously healthy 44-year-old woman during a total laparoscopic hysterectomy. Hyperventilation was observed to occur when the surgery was completed. Metabolic acidosis and hypoglycemia were demonstrated by blood gas analysis of the radial artery.

DIAGNOSIS

Metabolic acidosis.

INTERVENTIONS

The patient received sodium bicarbonate and 5% glucose fluid at the end of the surgery.

OUTCOMES

The tracheal tube was successfully removed when the tidal volume of the patient returned to normal after the therapy. However, the patient suffered pulmonary edema when she was transferred to the intensive care unit (ICU). With treatments with furosemide and sodium bicarbonate, acidosis and pulmonary edema were completely corrected at 8 hours after the surgery. On the second day after the surgery, the patient suffered nausea and vomiting. Nausea and vomiting were not completely relieved on the sixth day after the operation; therefore, the patient was transferred to the Department of Gastroenterology for further therapy.

LESSONS

This case suggests that although the concept of enhanced recovery after surgery (ERAS) has been adopted by most physicians because of its positive outcomes, the issue of prolonged fasting still exists, and such patients may be exposed to the risk of starvation ketoacidosis.

Psychopharmacological treatment of schizophrenia during pregnancy and lactation

PURPOSE OF REVIEW

It is necessary, in every-day clinical life when treating pregnant women with mental diseases, to reach quick decisions derived from recent comprehensive information. The knowledge of the use of antipsychotics in pregnancy has increased considerably in the last years. This review tries to summarize important considerations and facilitate clinical decisions.

RECENT FINDINGS

This review will cover not only the effects of exposure during pregnancy on outcomes, postnatal adaption syndrome and lactation, but also pharmacokinetic considerations on the use of antipsychotics during pregnancy.

SUMMARY

The recent publications have found only minimally increased risks for certain malformations, after using ever more sophisticated statistical models of analysis and reassuring amounts of data. Taken together, the quality of the studies has greatly improved and the results are reassuring with respect to the safety of the use of antipsychotics during pregnancy. The rates of weight gain and gestational diabetes warrant closer attention in the clinical setting.
