    Abstract Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by a decreased number of platelets and mucocutaneous bleeding. Many viruses have been identified as triggers of the autoimmune process, including human immunodeficiency virus (HIV), hepatitis C virus (HCV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), parvovirus, rubella, and measles. Association with the new severe acute respiratory syndrome coronavirus, SARS-CoV-2 infection (Covid-19 infection) has been rarely reported. Here, we report the oldest case of ITP patient triggered by the novel coronavirus infection. He showed inadequate response to IVIG but responded to corticosteroids with no severe adverse events. Further studies are warranted to determine the optimal therapeutic strategies for ITP with the Covid-19 infection.

    Long-Term Follow-Up of 15 Cases

    Abstract Objective: This paper prospectively evaluates the long-term followup [mean ± standard deviation (SD) duration: 89.7±19.4 months] data of 15 patients (13 females and 2 males) with refractory symptomatic immune thrombocytopenia (ITP) treated with rituximab. Materials and Methods: Rituximab was administered at 375 mg/m2 weekly for a total of 4 doses. Complete response (CR) was defined as a platelet count of ≥100,000/mm3 and partial response (PR) as a platelet count of ≥30,000/mm3 but less than 100,000/mm3. Early response (ER) and late response (LR) were defined as response within 42 days and after 42 days of initiation of rituximab therapy, respectively. Sustained response (SR) was defined as response lasting for at least 6 months. Results: Mean age (±SD) at the start of rituximab was 46.6±11.3 years. Mean platelet count (±SD) prior to rituximab treatment was 17,400±8878/mm3. The mean time (±SD) between rituximab therapy and response to rituximab in early responders and late responders was 1.8±1.3 weeks and 10±2.8 weeks, respectively. Mean durations (±SD) of ER and LR were 51±47.2 months and 6±4.2 months, respectively. Seven of the 15 patients (46.7%) showed an initial response to rituximab (5 ER and 2 LR). The rate of SR over 6 months was 26.7% (4/15). Among the responders to rituximab, 3 (3/7, 42.9%) maintained their response 1 year after rituximab treatment and 2 (2/7, 28.6%) had ongoing response 5 years after initiation of rituximab. Two of the 7 patients (28.6%) still maintained their response 98 months after initiation of rituximab. All 5 initial responders with subsequent relapse achieved response from subsequent treatment modalities (3 CR, 2 PR). Conclusion: Our data confirm, over a long period of observation, that rituximab is safe and effective in the management of patients with chronic refractory primary ITP.

    Abstract The risk of venous thromboembolism (VTE) increases in the presence of plasma cell dyscrasias. Monoclonal gammopathy of undetermined significance (MGUS) and multiple myeloma (MM) share an intrinsic increased risk of VTE. Treatment with thalidomide and lenalidomide further increases the incidence of VTE in certain MM patient subsets. The pathogenesis remains unclear, but probably involves several factors such as activation of procoagulant factors, acquired activated protein C resistance, and inflammation. In addition to general risk factors for VTE, such as older age, immobility, surgery, and inherited thrombophilia, there are some MM-specific and treatment-related factors that contribute to the increased risk. The risk for VTE is high under treatment with thalidomide or lenalidomide in combination with dexamethasone or multi-agent chemotherapy. We report 3 cases of MM with VTE with review of the literature. This review highlights the risk factors for VTE in MM and general, disease-specific and treatment-related mechanisms for thrombosis.

    Abstract Introduction. Infectious diseases may present with atypical presentations in the geriatric patients. While fever is an important finding of infections, it may also be a sign of noninfectious etiology. Methods. Geriatric patients who were hospitalized for acute fever in our infectious diseases unit were included. Acute fever was defined as presentation within the first week of fever above 37.3∘C. Results. 185 patients were included (82 males and 103 females). Mean age was 69.7±7.5 years. The cause of fever was an infectious disease in 135 and noninfectious disease in 32 and unknown in 18 of the patients. The most common infectious etiologies were respiratory tract infections (n=46), urinary tract infections (n=26), and skin and soft tissue infections (n=23). Noninfectious causes of fever were rheumatic diseases (n=8), solid tumors (n=7), hematological diseases (n=10), and vasculitis (n=7). A noninfectious cause of fever was present in one patient with no underlying diseases and in 31 of 130 patients with underlying diseases. Conclusion. Geriatric patients with no underlying diseases generally had infectious causes of fever while noninfectious causes were responsible from fever in an important proportion of patients with underlying diseases.
