Role of hospital anxiety and depression on the healing of chronic leg ulcer: A prospective study

Determinants of Quality of Life in Patients with Post-Thrombotic Syndrome

OBJECTIVES

Chronic post-thrombotic syndrome (PTS) may develop in up to 50% of patients after deep vein thrombosis (DVT) and may reduce patients' quality of life (QoL). We aimed to evaluate the association of PTS severity with QoL in patients with proximal DVT submitted to medical treatment and also to identify modifiable and non-modifiable risk factors related to PTS.

METHODS

Patients with iliac or femoropopliteal DVT observed in Vascular Surgery consultation in our institution from 1 year period with unilateral DVT were selected. Patients with total vein recanalization were excluded. Villalta scale was applied to assess PTS degree and VEINES-QoL/Sym questionnaire was used as a disease-specific QoL measure. Correlation between PTS degree and VEINES-QoL/Sym score and predictors of PTS were determined.

RESULTS

56 patients accepted to enter the study. From those, 66.1% were female, 64.3% (n=36) had iliac and 35.7% (n=20) femoropopliteal DVT. PTS was present in 52.8% of iliac and 65.0% of femoropopliteal DVT patients observed in consultation (P=0.413). There was a significant correlation with PTS degree and both VEINES-QoL and VEINES-Sym scores (P<0.001). Major depression (OR=5.63, P=0.045) and regular wear of compressing stockings (OR=4.69, P=0.041) were the only independent factors associated with PTS. Patients with depression had lower QoL scores, while patients with PTS who wear compression stockings had similar QoL scores compared to patients without PTS. Ultrasound alterations (OR=3.28, P=0.174), age, gender, iliac DVT, multiple DVT and time after DVT (P>0.2) were not associated with PTS syndrome.

CONCLUSIONS

VEINES-QoL/Sym had moderate inverse correlation with PTS degree. Depression was associated with both PTS and lower QoL scores. Patients with PTS criteria compliant to wearing compressing stockings had similar QoL scores to patients without PTS.

Psychological Stress on Wound Healing: A Silent Player in a Complex Background

Stress is hard to define and is further complicated by varied perceptions in the population and differing responses in different situations. Psychological stress brings about certain physiological changes through manipulation of the neural, humoral and immunological systems. Observational studies have showed that fear and anxiety before surgery can complicate normal wound healing. Two different pathways appear to be involved: one directly through hypothalamic-pituitary-adrenal axis and sympathetic-adrenomedullary axis, and another indirectly through negative psychological stressors such as anxiety, depression and social isolation. The pathogenesis includes decreased expression of pro-inflammatory cytokines, resulting in poor angiogenesis, matrix regeneration and delayed healing. Prolonged immunological activation in itself is a stressor and can precipitate a sickness behaviour syndrome manifested by disturbed sleep, anorexia, reduction in activity, increased responsiveness to pain and addiction to alcohol and tobacco. It has been observed that cortisol release suppresses pro-inflammatory cytokine release, while down-regulation of cortisol causes unabated inflammatory response. In individuals with chronic wounds, on the other hand, it is thought that physical stress has different effects such as foul odor, pain, exudate and social and familial isolation, which may act independently as psychological stressors. This article attempts to appraise the influence of psychological stress on the immunological system and its effect on wound healing.

Role of hospital anxiety and depression on the healing of chronic leg ulcer: A prospective study

A chronic leg ulcer is a debilitating illness, owing to the local condition of the wound and a decrease in physical activity and productivity, resulting in anxiety and depression among patients. The study aimed to find any association of anxiety and depression in the healing of chronic wounds. A total of 125 patients with chronic leg ulcers were enrolled in the study. HADS questionnaire assessment followed the local wound examination in all patients. A follow-up assessment of the ulcer was done after appropriate local treatment, and data analysed with the HADS scale. In the present study, the ROC curve showed a cutoff value of 14 for the HADS score in predicting ulcer status (non-healing vs healed) after 30 days. A total of 54.4% (68) patients had a HADS score ≥ 14 and 39% (49) were true positive for the non-healing wound at a 1-month follow-up. This study revealed a sensitivity and specificity of 83.1% and 71.2%, respectively (P-value <.001), and diagnostic accuracy of 76.8%, for HADS score > 14 in the detection of non-healing ulcers. Chronic leg ulcers should be subjected to HADS assessment and if found significant corrective measures must be instituted for improving wound healing.
