Introduction

In 2011, the FDA issued an alert recommending not

to prescribe citalopram high doses, due to QT prolongation risk.

We explored the clinical background of QT interval prolongation

related to serotonin selective reuptake inhibitors (SSRI) use and

the clinical implications of safety issues.

Methodology

A review was conducted to clarify the mechanisms

associated with the occurrence of TdP when using SSRI and inves-

tigating therapeutic measures to avoid/minimize these effects. The

literature search was conducted in PubMed data reviewing articles

between 2001 and 2016.

Results

(1) Related to risk factors/intraclass differences: risk fac-

tors are increase in QTc interval

60ms from the pretreatment

value, advanced age, female sex, acute myocardial infarction and

electrolytic abnormalities among others. Citalopram appears more

likely than others to induce this phenomenon but its importance

is under current debate. (2) Related to dose: drug-induced QTc

interval prolongation and TdP was associated to citalopram in

doses > 40mg/day. However, psychotropic drug-induced sudden

cardiac death may be an outlier in the absence of identified risk

factors for QTc interval prolongation and TdP. (3) Related to poly-

pharmacy/management: there is an additive effect when using SSRI

and antipsychotics (EKG control is recommended in those cases).

Cross-sectional studies showed that SSRI use was not associated

with QT interval prolongation. This could be explained by the EKG

intra-intersubject variability.

Conclusions

There is little evidence that drug-associated QTc

interval prolongation by itself is sufficient to predict TdP. Future

research needs to improve its precision to better understand the

factors that facilitate/attenuate that progression. Clarifying this

may lead to a safer SSRI use.

Introduction

The literature concerning possible cardio-toxic

effects of lithium therapy in man is reviewed.

Methodology

A review was conducted to clarify the mechanisms

associated with the occurrence of conducting abnormalities when

using lithium and investigating (if so) whether these alterations

depend on the dose. The literature searchwas conducted in PubMed

data reviewing articles between 1982 and 2015.

Results

(1) Related to pathopsychiology/risk factors: reports

indicate T wave morphology changes with lithium therapy. Of par-

ticular concern are cases of sinus mode dysfunction or sinoatrial

block and the appearance or aggravation of ventricular irritabil-

ity. The incidence of cardiac complications, in general terms,

may increase with age. Recent findings (a retrospective study

of bipolar patients) of lithium-associated hypocalcaemia showed

that hypocalcaemia resulting from medical diseases and bipolar

patients with lithium-associated hypocalcaemia had significantly

higher frequencies of conduction defects. (2) Related/unrelated to

dose: therapeutic and toxic levels of lithium have infrequently

been associated with serious cardiac dysfunction. Several case

reports demonstrate two important points about Brugada syn-

drome unmasking: electrocardiograph abnormality severity may

correspond to lithium levels and unmasking may occur in the ther-

apeutic range of lithium. Other report shows a case of lithium

induced sinus-node dysfunction in a patient with serum lithium

levels in therapeutic range.

Conclusions

Lithium abnormalities are rare and mostly not

related to dose. Conducting heart anomalies may occur, especially

when several factors are present (such as age or co-morbid illnesses

that affect calcium serum levels).

Introduction

It is well known that hyperprolactinemia increases

the risk of hypogonadism, osteoporosis and cardiovascular dis-

eases. Atypical anti-psychotics are directly related with its

development. Despite its importance, pharmacological hyperpro-

lactinemia it is not considered and treated by psychiatrists as much

as expected. Nowadays, long-acting aripiprazole is one of the main

treatments that barely increase the prolactin (PRL) levels.

Objectives

To determine the number of cases in which PRL levels

are detected. To quantify the reduction of PRL levels with patients

treated with long-acting aripiprazole.

Methods

Observational, descriptive study, from February 2015

to July 2016, of 52 patients treated with anti-psychotics, in two

Sevillian community mental health centers.

Results

In 56% of cases, PRL level was measured at least one time:

in 77% of cases with prescription of long-acting aripiprazole, PRL

levels are reduced.

Conclusion

First step to reduce the impact of hyperprolactine-

mia in patients is to determine the PRL levels in a systematic way

being this practice a must to be considered. In the study carried

out and described in this abstract, reduction of PRL levels in target

populations using long-acting aripiprazole is observed.

Objectives

Clozapine is an atypical anti-psychotic used in the

treatment of schizophrenia and other psychotic disorders. It is

associated with several side effects, namely, hematologic disor-

ders, the more common being agranulocytosis. Some cases of
