ABSTRACT The hypothesis of this study was that D dimer, a specific degradation product of cross-linked fibrin, would be increased in the bronchoalveolar lavage (BAL) fluids of patients with sarcoidosis and that it would be related to other BAL parameters of disease activity. Eight of 10 sarcoidosis patients but none of 18 healthy volunteers had detectable BAL D dimer by enzyme immunoassay. Autoradiography revealed the presence of fibrinogen and D dimer in the BAL fluids from sarcoidosis patients. Bronchoalveolar lavage D dimer levels in sarcoidosis patients correlated with total BAL cells per milliliter, lymphocytes per milliliter, and total protein level, but not macrophages per milliliter. The D dimer in the BAL fluids from sarcoidosis patients did not correlate with D dimer in the blood. Our findings indicate that BAL D dimer parallels directly the lymphocytic alveolitis that characterizes pulmonary sarcoidosis.

    ABSTRACT: We would like to report a case of a 29-year-old male patient who presented with multiple lymphadenopathy and vague symptoms of low grade fever, cough, weight loss, rashes, vomiting, dry eyes and dry mouth. Physical examination revealed submandibular lymphadenopathy, vasculitic rashes over both lower limbs, and parotid gland enlargement. Blood investigations showed mild anemia with leukocytosis, predominantly eosinophilia and high erythrocyte sedimentation rate and C-reactive protein. Computed tomography of the neck, thorax and abdomen showed bilateral submandibular, submental adenopathy, mediastinal and para-aortic lymphadenopathy with generalized reticulonodular densities in both lower lobes. There were hepatomegaly and bilateral enlarged kidneys with renal cyst. Histopathological examination from the cervical lymph node later revealed non-caseating granuloma, consistent of sarcoidosis. Patient responded well to prednisolone 50 mg daily with subsequent reduction in the size of cervical lymphadenopathy and parotid swelling. KEYWORDS: Lymphadenopathy; Granuloma; Sjogren; Sarcoidosis.

    ABSTRACT: A recently published report from the United Kingdom suggested an association between sarcoidosis and pulmonary embolism (PE). We sought to examine whether this association was present among US decedents with sarcoidosis. We used data from the National Center for Health Statistics to investigate the association between sarcoidosis and PE among US decedents from 1988 to 2007. From 1988 to 2007, there were 46,450,489 deaths in the United States and 23,679 decedents with sarcoidosis mentioned on their death certificates. Among these, 602 (2.54%) had PE mentioned on their death certificates, compared with only 1.13% of the background population (P < .0001 for comparison). The association between sarcoidosis and PE was significant regardless of gender (OR, 2.07; 95% CI, 1.80-2.39; P < .0001 for men and OR, 1.76; 95% CI, 1.59-1.96; P ≤ .0001 for women) or race (OR, 1.57; 95% CI, 1.41-1.76; P < .0001 for blacks and OR, 1.87; 95% CI, 1.63-2.14; P < .0001 for whites). Among decedents with sarcoidosis, there was no difference in risk of PE between men and women (2.30% vs 2.54%, χ(2) = 1.32, P = .25) or between blacks and whites (2.60% vs 2.23%, χ(2) = 3.09, P = .08). The association between sarcoidosis and PE held regardless of age. Using death certificate data from 1988 to 2007, we detected an association between sarcoidosis and PE regardless of gender, race, or age. Further investigation is needed to decipher the mechanisms of this apparent association.
