Background: Therapyrelated mucositis is associated with considerable morbidity. This complication following allogeneic stem cell therapy (alloSCT) is less severe after reduced intense conditioning (RIC); however, even here it may be serious. Methods: 52 patients (male: n = 35 (67%), female: n = 17 (33%)) at a median age of 62 years (35–73 years) underwent alloSCT after RIC. Conditioning was either total body irradiation (TBI)<sub>2Gy</sub>/±fludarabine (n = 33, 63.5%) or chemotherapy based. Graftversushost disease (GvHD) prophylaxis was carried out with cyclosporine A ± mycophenolate mofetil (MMF). 45 patients (87%) received shortcourse methotrexate (MTX). Mucositis was graded according to the Bearman and the World Health Organisation (WHO) scale. A variety of parameters were correlated with mucositis. Results: The Bearman and WHO scales showed excellent correlation. Mucositis was significantly more severe after chemotherapybased conditioning compared to conditioning with TBI<sub>2Gy</sub>/±fludarabine (p < 0.002) as well as in cases with an increase in creatinine levels above the upper normal value (UNV) on day +1 after SCT (p < 0.05). Furthermore, the severity correlated with time to engraftment of leucocytes (correlation coefficient (cc) = 0.26, p < 0.02) and thrombocytes (cc = 0.38, p < 0.001). Conclusions: The conditioning regimen and increased creatinine levels at day +1 were identified as factors predicting the severity of mucositis after RICSCT. Creatinine levels on day +1 after SCT may help identify patients at risk for severe mucositis in the further course of transplantation.
Background: Patients with mucin-producing adenocarcinoma have an increased risk for venous and arterial thrombosis. When these patients present with thrombocytopenia, disseminated intravascular coagulopathy (DIC) is often the underlying cause. Case Report: We report 2 patients who were admitted due to bleeding symptoms of unknown cause, in whom further workup revealed adenocarcinoma-induced DIC. Conclusion: In elderly patients presenting with signs of DIC, such as reduced fibrinogen levels, elevated prothrombin time, elevated D-dimer, and thrombocytopenia, without any obvious reason (e.g., sepsis), adenocarcinoma-associated coagulopathy should be considered as the underlying cause. Paradoxically, in these patients bleeding symptoms improve when the patient is sufficiently anti-coagulated with low molecular weight heparin. Treatment of the underlying disease is of central importance in controlling acute or chronic DIC associated with malignant diseases and chemotherapy should be started as soon as possible.
