OBJECTIVETo investigate the clinical features of β-thalassaemia intermediate (TI) patients and the curative effect and side reactions of hydroxyurea therapys.

METHODSTwenty nine patients with TI were divided into hydroxyurea therapy group and no hydroxyurea therapy group; the curative effect and side reactions in 2 groups were compared; the situation of blood transfusion in the 2 groups was evaluated.

RESULTSIn hydroxyurea therapy group, the hemoglobin level increased after treatment for 3 months; the reticulocyte percentage obviously decreased after treatment for 12 months; the serum ferritin had been maintained at a low level; while in no hydroxyurea therapy group, the levels of hemoglobin and reticulocytes were not significantly improved after treatment, the serum ferritin level gradually increased. In hydroxyurea therapy group, 12 cases were out of blood transfusion after treatment for 12 months, effective rate of treatment was 85.71%; while in no hydroxyurea therapy group, the blood transfusion dependency was not improved after treatment. No serious side reactions were found in all the hydroxyurea treated patients.

CONCLUSIONThe hydroxyurea shows a better curative effect on TI patients, no serious side reactions occur in all the patients treated with hydroxyurea, but the long-term curative effect and side reactions should be observed continuously.

Anemia is one of the commonest extraintestinal manifestations of inflammatory bowel disease (IBD). The pathogenesis of anemia in IBD is complex but iron deficiency combined with inflammation is the most common factor related to the development of anemia. However, other causes such as vitamin B12 and folate deficiency, hemolysis, myelosuppression and drug also should not be overlooked. In addition to ferritin, inflammatory markers and new biochemical parameters such as hepcidin and ferritin index are being tested as diagnostic a tool. First step for treatment is disease activity control and iron supplementation. Although oral iron is widely used, intravenous iron therapy should be considered in patients who are intolerant to oral iron therapy, have severe and refractory anemia or are in active disease state. Recently, new intravenous iron formulations have been introduced and due to their safety and easy usage, they have become the standard treatment modality for managing anemia in IBD. Erythropoietin and transfusion can be considered in specific situations. Vitamin B12 and folate supplementation is also important in patients who are deficient of these micronutrients. Since anemia in IBD patients could significantly influence the disease outcome, further studies and standard guideline for IBD are needed.

OBJECTIVE: To compare the clinical efficacy and safety of oral administration of Buxue Yimu Pills (BYP, ), ferrous sulfate (FS), and the combination of BYP and FS on gynecological anemia, and investigate the mechanisms using network pharmacology. METHODS: A randomized, controlled, multi-center clinical trial was conducted. Totally 150 patients with hemoglobin of 70-110 g/L due to gynecological conditions were recruited and randomized (using the block randomization method) into Buxue Yimu Pills group (24 g/d), oral iron group (FS Tablets, 0.9 g/d), and combined treatment group (BYP, 24 g/d plus FS Tablets, 0.9 g/d), 50 patients in each group. At the enrollment and 4-week treatment, complete blood count, serum iron indexes were evaluated. Adverse events, liver and renal functions, as well as blood coagulation were observed. Network pharmacology was conducted to identify the active ingredients and explore the potential mechanisms of BYP. RESULTS: Ten (20%) and 7 (14%) participants discontinued the therapy due to gastrointestinal symptoms in oral iron and combination treatment groups. All 3 groups showed elevated hemoglobin. The patients in the iron group exhibited typically elevated in serum iron and ferritin and decreased in total iron-binding capacity. No change in iron indexes was observed in BYP group. The patients in the combination treatment group neither showed significant changes in serum ferritin nor total iron-binding capacity. No significant adverse reactions were observed in the BYP group. The network pharmacology identified 27 bioactive compounds and 145 targets of BYP on gynecological anemia. Biological processes and pathways including regulation of inflammation, hormone, angiogenesis and hemostasis, response to decreased oxygen levels, effects on myeloma cell, and response to metal ions were identified. CONCLUSION BYP contributes to the practical improvement on gynecological anemia potentially through multi-target mechanisms and optimized iron re-distribution. (Trial registration: No. NCT03232554).

To investigate the clinical and immunological features of dermatomyositis (DM) complicated with macrophage activation syndrome (MAS). The demographic and clinical characteristics of five patients diagnosed with DM complicated with MAS hospitalized in the Department of Rheumatology and Immunology, Peking University People ' s Hospital from 2011 to 2021 were collected. The results of clinical manifestations, laboratory tests, immunological features, treatments and prognosis were analyzed and summarized. In this study, five female patients in Peking University People's Hospital with an average age of 63.8 (44.0-83.0) years and an average disease duration of 16.1 (1.5-48.0) months. All the patients had typical DM rash (such as heliotrope sign, V/shawl sign or Gottron's sign/papules). They all had muscle involvement (including myalgia or muscle weakness). Two patients had positive myositis-specific antibodies (MSAs), in which case 1 had anti-TIF1-γ antibody and case 5 had anti-NXP-2 antibody. Four patients had interstitial lung disease except case 3. All of the cases developed MAS in the active stage of DM. Common manifestations of MAS in these five patients included high-grade fever, cytopenia, decreased fibrinogen, elevated ferritin and increased soluble CD25. Case 1 presented with neutropenia (0.6×10⁹ /L), thrombocytopenia (26.0×10⁹ /L), hypofibrinogenemia (0.9 g/L), markedly elevated ferritin (26 331.0 μg/L), decreased NK cell activity. Case 2 had anaemia (hemoglobin 81.0 g/L), thrombocytopenia (55.0×10⁹ /L), hypertriglyceridemia (4.7 mmol/L), hypofibrinogenemia (1.2 g/L), elevated ferritin (>100 000.0 μg/L), hemophagocytosis in bone marrow. Case 3 had anaemia (hemoglobin 88 g/L), decreased fibrinogen (1.9 g/L), increased ferritin (>27 759.0 μg/L), splenomegaly, hemophagocytosis in bone marrow. Case 4 suffered from neutropenia(0.3×10⁹ /L), anaemia(hemoglobin 78 g/L), hypertriglyceridemia (4.2 mmol/L), hypofibrinogenemia (0.9 g/L), increased ferritin (>100 000.0 μg/L), and decreased NK cell activity. Case 5 presented anaemia (hemoglobin 60.0 g/L), thrombocytopenia (67.0×10⁹ /L), hypertriglyceridemia (12.7 mmol/L), decreased fibrinogen (1.1 g/L), and elevated ferritin (>923.0 μg/L). All the patients were treated with methylprednisone pulse therapy (200-500 mg) combined with cyclosporine while case 5 received rituximab after methylprednisone pulses. In addition, case 3 also received the combination of mycophenolate mofetil. Case 1 was given etoposide while case 4 was treated with cyclophosphamide and repeated plasmapheresis at the same time. Moreover, intravenous immunoglobulin was added meantime apart from case 3. The condition of four patients improved significantly, nevertheless case 4 experienced recurred pulmonary symptoms and died of respiratory failure. As for complications about infection, case 2 had bacterial infection with high level procalcitonin (PCT) before MAS treatment and condition was improved after empiric antibacterial therapy. Case 3 had cytomegalovirus DNAemia before diagnosis of MAS and viral titer turned negative after ganciclovir therapy. After treatment of MAS, four patients developed cytomegalovirus DNAemia except case 3, in which case 5 was co-infected with bacteria. To sum, DM complicated with MAS is relatively rare, and its patients are of ten in life-threatening condition. Early detection, treatment and prevention of infection during treatment are critical to improve the prognosis.

Hemophagocytic syndrome (HPS) is a severe disease characterized by excessive release of inflammatory cytokines caused by abnormal activation of lymphocytes and macrophages, which can cause multiple organ damage and even death. Panniculitis is a disease characterized by inflammation of subcutaneous adipose tissue. We effectively treated 2 patients with panniculitis-associated HPS with ruxolitinib. Case 1: A 70-year-old male started with intermittent plantar swelling and pain, and then developed leukocytosis, mild anemia, multiple red maculopapules with painless subcutaneous nodules on the forehead, neck and bilateral lower legs. The patient was treated with prednisone and leflunomide for improvement. After that, repeated fever and rash occurred again. After admission to our hospital, we found his leukocyte and hemoglobin decreased, ferritin raised, fibrinogen and natural killer (NK) cell activity decreased, and hemophagocytic cells were found in bone marrow aspiration. The skin pathology was consistent with non-suppurative nodular panniculitis. He was diagnosed with nodular panniculitis associa-ted HPS. He was treated with glucocorticoid, cyclosporine, etoposide and gamma globule, but the disease was not completely controlled. After adjusting etoposide to ruxolitinib, his symptoms and abnormal laboratory findings returned to normal. After 2 months he stopped using ruxolitinib due to repeated infections. During the follow-up, though the prednisone dose was tapered, his condition was stable. Case 2: A 46-year-old female patient developed from intermittent fever, erythematous nodular rash with tenderness, leukopenia, and abnormal liver function. antibiotic therapy was ineffective. She improved after glucocorticoid treatment, and relapsed after glucocorticoid reduction. There were fever, limb nodules, erythema with ulcerative necrosis, intermittent abdominal pain when she came to our hospital. Blood examination showed that her white blood cells, red blood cells and platelets were decreased, fibrinogen was decreased, triglyceride was increased, ferritin and soluble interleukin-2 receptor(SIL-2R/sCD25) were significantly raised, and hemophagocytic cells were found in bone marrow aspiration. It was found that Epstein-Barr virus DNA was transiently positive, skin Staphylococcus aureus infection, and pulmonary Aspergillus flavus infection, but C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were normal, and no evidence of tumor and other infection was found. Skin pathology was considered panniculitis. The diagnosis was panniculitis, HPS and complicated infection. Antibiotic therapy and symptomatic blood transfusion were given first, but the disease was not controlled. Later, dexamethasone was given, and the condition improved, but the disease recurred after reducing the dose of dexamethasone. Due to the combination of multiple infections, the application of etoposide had a high risk of infection spread. Ruxolitinib, dexamethasone, and anti-infective therapy were given, and her condition remained stable after dexamethasone withdrawal. After 2 months of medication, she stopped using ruxolitinib. One week after stopping using ruxolitinib, she developed fever and died after 2 weeks of antibiotic therapy treatment in a local hospital. In conclusion, panniculitis and HPS are related in etiology, pathogenic mechanism and clinical manifestations. Abnormal activation of Janus-kinase and signal transduction activator of transcription pathway and abnormal release of inflammatory factors play an important role in the pathogenesis of the two diseases. The report suggests that ruxolitinib is effective and has broad prospects in the treatment of panniculitis associated HPS.

OBJECTIVETo explore the efficacy and safety of deferasirox in aplastic anemia (AA)patients with iron overload.

METHODSA single arm, multi- center, prospective, open- label study was conducted to evaluate absolute change in serum ferritin (SF)from baseline to 12 months of deferasirox administration, initially at a dose of 20 mg·kg(-1)·d(-1), and the safety in 64 AA patients with iron overload.

RESULTSAll patients started their deferasirox treatment with a daily dose of 20 mg · kg(-1) ·d(-1). The mean actual dose was (18.6±3.60) mg · kg(-1)·d(-1). The median SF decreased from 4 924 (2 718- 6 765)μg/L at baseline (n=64) to 3 036 (1 474- 5 551)μg/L at 12 months (n=23) with the percentage change from baseline as 38%. A median SF decrease of 651 (126-2 125)μg/L was observed at the end of study in 23 patients who completed 12 months' treatment, the median SF level decreased by 1 167(580-4 806)μg/L [5 271(3 420-8 278)μg/L at baseline; 3 036(1 474-5 551)μg/L after 12 months' treatment; the percentage change from baseline as 42% ] after 12 months of deferasirox treatment. The most common adverse events (AEs) were increased serum creatinine levels (40.98%), gastrointestinal discomfort (40.98%), elevated liver transaminase (ALT: 21.31%; AST: 13.11%)and proteinuria (24.59%). The increased serum creatinine levels were reversible and non-progressive. Of 38 patients with concomitant cyclosporine use, 12(31.8%)patients had two consecutive values >ULN, 10(26.3%)patients had two consecutive values >1.33 baseline values, but only 1(2.6%)patient's serum creatinine increased more than 1.33 baseline values and exceeded ULN. For both AST and ALT, no patients experienced two post- baseline values >5 ×ULN or >10 × ULN during the whole study. In AA patients with low baseline PLT count (less than 50 × 10(9)/L), there was no decrease for median PLT level during 12 months' treatment period.

CONCLUSIONSAA patients with iron overload could achieve satisfactory efficacy of iron chelation by deferasirox treatment. The drug was well tolerated with a clinically manageable safety profile and no major adverse events.

BACKGROUND: Iron deficiency anemia is the most common form of anemia in India. Hemoglobin A1c (HbA1c) is used in diabetic patients as an index of glycemic control reflecting glucose levels of the previous 3 months. Like blood sugar levels, HbA1c levels are also affected by the presence of variant hemoglobins, hemolytic anemias, nutritional anemias, uremia, pregnancy, and acute blood loss. However, reports on the effects of iron deficiency anemia on HbA1c levels are inconsistent. We conducted a study to analyze the effects of iron deficiency anemia on HbA1c levels and to assess whether treatment of iron deficiency anemia affects HbA1c levels. METHODS: Fifty patients confirmed to have iron deficiency anemia were enrolled in this study. HbA1c and absolute HbA1c levels were measured both at baseline and at 2 months after treatment, and these values were compared with those in the control population. RESULTS: The mean baseline HbA1c level in anemic patients (4.6%) was significantly lower than that in the control group (5.5%, p<0.05). A significant increase was observed in the patients' absolute HbA1c levels at 2 months after treatment (0.29 g/dL vs. 0.73 g/dL, p<0.01). There was a significant difference between the baseline values of patients and controls (0.29 g/dL vs. 0.74 g/dL, p<0.01). CONCLUSIONS: In contrast to the observations of previous studies, ours showed that HbA1c levels and absolute HbA1c levels increased with treatment of iron deficiency anemia. This could be attributable to nutritional deficiency and/or certain unknown variables. Further studies are warranted.

OBJECTIVETo explore the effects of serum ferritin (SF) and iron overload (IO) pre-immunosupressive treatment (IST) on hematologic response of severe aplastic anemia (SAA/VSAA) patients treated with IST.

METHODS257 SAA/VSAA patients who underwent first-line IST from Feb, 2003 to Dec, 2011 in Anemia Therapeutic Centre, Institute of Hematology and Blood Diseases Hospital were retrospectively analyzed, the status of SF before IST and the IO-affected factors were studied. The effects of IO on hematologic response of SAA/VSAA patients were evaluated as well.

RESULTSThe median level of SF of 257 patients was 387 (6-2 004) μg/L. 36 patients (14%) had IO, including 20 SAA and 16 VSAA patients. According to univariate logistical regression analyses, IO was influenced by age>14 years (P=0.010) and blood transfusion (P<0.001). The multivariate logistic regression analysis showed that blood transfusion [P=0.001, OR=0.218 (95% CI 0.092-0.520)] was the only independent prognostic factor. SAA (but not for VSAA) patients with IO had much lower hematologic response rate in 6 month after IST (P=0.037). Absolute reticulocyte count and IO correlated with response at 6 month by univariate logistical regression analysis (P=0.014, 0.037). The multivariate logistic regression analysis showed that IO [P=0.021, OR=4.092 (95% CI 1.235-13.563)], ARC ≥20×10(9)/L [P=0.040, OR=2.743 (95% CI 1.049-7.175)] were independent prognostic factors.

CONCLUSION84.8% patients had high serum ferritin before IST, and 14.0% reached IO. Adult and more blood transfusion caused IO more likely. IO correlated with response at 6 month, and was independent prognostic factor.

OBJECTIVETo observe the therapeutic effect of shengxuening (SXN) in treating iron-deficiency anemia (IDA) and to explore its molecular mechanism on iron metabolism balance regulation.

METHODSPatients with IDA were randomly divided into the treated group and the control group, 50 in each group. They were treated with SXN (0.1 g, three times per day) and ferrous gluconate (0.1 g, three times per day) respectively, for 30 days. Levels of serum iron (Fe), total iron binding capacity (TIBC), transferrin saturation (TS), serum ferritin (SF), transferrin (Tf), soluble transferrin receptor (sTfR) and blood routine test, as well as scoring of TCM qi-blood deficiency Syndrome were conducted before and after treatment.

RESULTSThe total effective rate in the treated group reached 92%, it was shown that SXN could improve the iron metabolism, increase levels of Fe, TS, SF and reduce levels of TIBC, Tf, sTfR, it has obvious effect in promoting erythrocyte generation and could promote formation of leucocytes and platelets. The total effective rate in the control group was 32%, which was significantly lower than that in the treated group (P < 0.01).

CONCLUSIONThe effect of SXN in treating IDA and qi-blood deficiency Syndrome is evident, it could improve the iron metabolism, increase levels of Fe, TS, SF and lower levels of TIBC, Tf, sTfR.
