ABSTRACT
BACKGROUND: Vitamin D plays a seminal role in many homeostatic mechanisms. In this study, we assessed the correlation between circulating vitamin D levels and mortality rates in critically ill patients. METHODS: All patients admitted to the intensive care units (ICUs) and internal medicine wards in a university-based hospital that required mechanical ventilation were admitted. Data collected included the underlying disease, basic hematological and biochemical blood test results, APACHE II scores and serum 25-hydroxyvitamin D [25(OH)D] levels. The primary end point was defined as all-cause mortality within 60 days from admission or from acute deterioration. RESULTS: Between December 2008 and June 2009, 130 patients were enrolled. Average vitamin D concentration was 14.04 ± 6.9 ng/ml; 107 patients were vitamin D deficient (< 20 ng/ml). Total mortality rate after 60 days was 44.3%. Vitamin D levels were correlated with white blood cell (WBC) count, but with no other measured variable. Among the deceased patients, survival curves indicated that survival of patients with vitamin D deficiency was significantly shorter than those whose vitamin D concentration was >20 ng/ml (P < 0.05); the average survival time was 15.3 ± 12.4 days for vitamin D deficient patients compared with 24.2 ± 16.5 days among those with normal vitamin D levels. CONCLUSION: This study demonstrated that low vitamin D levels are common among patients admitted to ICU. We observed longer survival times among vitamin D sufficient patients. Our results indicate that vitamin D concentration may be either a biomarker of survival or a co-factor. We recommend assessing the effects of vitamin D supplementation in critically ill patients.

The SAPHO syndrome may evolve following low virulent infections. This report describes a patient who developed a clinical syndrome that complied with the formal diagnostic criteria of the SAPHO following an infection with syphilis. His clinical manifestations gradually resolved following antibiotic therapy. This interesting association underlines the pathogenic circumstances linking infections and various rheumatic conditions. It is less evident whether resolution of the symptoms was ascribed to the eradication of the bacteria or perhaps due to cessation of the auto-inflammatory reaction to the infection induced. In our description we suggest a correlation between infection with Treponema pallidum and the induction of SAPHO syndrome.

OBJECTIVES: Fibromyalgia syndrome (FMS) has been associated with various psychiatric and other, ill-defined disorders. We recently showed that fibromyalgia is more prevalent in men suffering from combat-related Post Traumatic Stress Disorder (PTSD). In this paper we analyze the relationship between engagement in physical activity, the psycho-metric traits of PTSD and the future development of FMS. METHODS: Fifty-five male patients, all known to have combat-related PTSD, were investigated for the presence of fibro-myalgia according to the American College of Rheumatology (ACR) criteria. Each patient completed questionnaires characterizing his quality of sleep, and the Sheehan Disability Scale measuring performance in the familial, social and vocational spheres. Additionally, each of the enrollees was interviewed by an experienced psychiatrist, who then completed a Clinician Administered PTSD Scale, a Clinical Global Impression Scale, and calculated an SF-36 score. Each patient was asked whether he exercised often, occasionally or not at all. The data was analyzed by the chi2 test and by ANOVA. RESULTS: PTSD patients who also suffered from FMS had a more severe form of disease as measured by the Clinician Administered PTSD Scale (CAPS) score, 88.2 +/- 14.0 (n = 28) compared to 97.6 +/- 13.2 of patients with PTSD and FMS (n = 27) (p = 0.013, F(d.f 2)-6.61, ANOVA test). Interestingly, engaging in physical exercise was also associated with less severe disease. When the patients were analyzed based on their tender point count (0-5, 6-10, or > 11), the number of tender points decreased with increasing physical activity (p = 0.02, chi2(d.f.-4) = 11.3). CONCLUSION: Physical exercise in male patients with combat-related PTSD provides protection from the future development of fibromyalgia. Furthermore, physical activity is related in this group of patients to a better perception of their quality of life.
