Several studies along the last two decades provide information indicating the relationship between posttraumatic stress disorder (PTSD) and obsessive compulsive disorder (OCD). The particular features described in patients who developed OCD symptoms closely after the onset of PTSD, may suggest the existence of a specific subtype of OCD more likely to be suffered after a traumatic event. The few studies focused on evaluating treatment efficacy for the association between OCD and PTSD seem to predict poor response to pharmacologic or behavioral cognitive (BCT) monotherapy.

Despite the evidence, most widely used guidelines propose the employment of either a psychotherapeutic or psychopharmacologic approach. We propose to combine intensive BCT and serotonin profile antidepressants in order to optimize PTSD-OCD subtype.

We present two detailed case reports offering the results of combining intensive BCT and serotonin profile antidepressants as soon as the comorbid diagnosis for both disorders was established. These two patients were recruited from outpatient care centers.

Our limited experience supplied promising outcome results. Significant improvement regarding to functional impairment appeared from early stages of the treatment in both patients.

Despite logistic difficulties, an intensive and coordinated psychopharmacologic and psychotherapeutic approach might constitute another treatment choice which may be taken into account in those cases monotherapy fails to reduce PTSD-OCD subtype patients’ impairment.

A mixed treatment approach might be taken into account as a first line treatment in PTSD-OCD disorder.
