Concurrent congenital hemophilia B and acquired hemophilia A: a unique case report

Congenital hemophilia B is a rare X-linked recessive bleeding disorder caused by factor IX deficiency. Acquired hemophilia A is a rare, acquired bleeding disorder that presents with new-onset bleeding, especially in older adults, due to the development of auto-antibodies against factor VIII (FVIII). This case report presents the medical management of a patient with congenital hemophilia B and acquired hemophilia A. We highlight the limitations of maintaining factor levels with factor replacement therapy alone, particularly in hemophilia patients who have developed factor inhibitors. In addition, we draw attention to the need for dose escalation, the cost, and the need for immune-tolerance induction therapy. This case illustrates that when the current diagnosis does not explain the full clinical picture and laboratory data are inadequate, it is important to continue to seek alternative diagnoses and cost-effective treatment.

The effect of thrombocytapheresis on hemogram and biochemistry parameters in patients with essential thrombocytemia

BACKGROUND

Essential thrombocythemia is one of the chronic myeloproliferative neoplasms characterized by clonal proliferation of myeloid cells with variable morphological maturation and hematopoietic activity.It is characterized by excessive clonal platelet production with a tendency to thrombosis and bleeding. Thrombocytapheresıs is the removal of platelets by apheresis techniques. Thrombocytapheresıs is generally recommended in patients with essential thrombocythemia with acute, severe thrombotic or hemorrhagic events.

METHODS

The study included 39 patients who were diagnosed with essential thrombocythemia, started cytoreductive and aspirin therapy, and underwent thrombocytapheresıs due to the development of acute severe thrombotic or hemorrhagic events, diagnosed in the adult hematology clinic of İnönü University Turgut Ozal Medical Center. Hemogram and biochemistry values of the patients were scanned retrospectively.

RESULTS

After thrombocytapheresıs, a statistically significant difference was found between the first and last measurements of hemoglobin, mean platelet volume, White blood cell, neutrophil, platelet, platelet distribution width, creatine, lactate dehydrogenase, fibronogen and calcium levels of the patients.

CONCLUSION

The use of thrombocytapheresıs in patients with essential thrombocytosis causes a rapid decrease in platelet values as well as an effect on hemogram and biochemistry parameters. Other hemogram and biochemistry parameters such as platelet value should be monitored in patients.

Effect of extracorporeal photopheresis on survival in acute graft versus host disease

BACKGROUND

Extracorporeal photopheresis (ECP) is the main non-pharmacological approach accompanying systemic medical treatments in steroid-resistant acute or chronic graft versus host disease. The study aimed to examine the effect of ECP on survival in acute graft versus host disease (aGVHD).

METHODS

A total of 35 patients who were followed up in the adult hematology clinic of İnönü University Turgut Özal Medical Center for aGVHD were included in the study. Stem cell transplantation and ECP application parameters that may affect the survival of the patients were examined.

RESULTS

In aGVHD using ECP, the degree of involvement affects survival. Involvements with a clinical and laboratory score (Glucksberg system) of 2 and above significantly reduced survival. The duration of ECP use is associated with survival. Especially, 45 days and longer use increases survival (hazard ratio, P-value <.05). The duration of steroid use was found to be effective in survival in aGVHD (P < .001). ECP administration day (P = .003), duration of steroid use (P < .001), duration of ECP use (P = .001), and grade of aGVHD (P < .001) affect survival.

CONCLUSION

ECP use is effective in survival in patients with aGVHD score ≥2. In patients with aGVHD, especially the use of 45 days and longer has a positive effect on survival. The duration of steroid use is associated with survival in aGVHD.

Does ferritin level affect the outcomes of autologous stem cell transplantation equally in all diseases?

BACKGROUND

In this retrospective study, we evaluated the effect of ferritin levels on the outcomes of autologous stem cell transplantation in patients with MM or lymphoma.

METHODS

In this study, 170 patients with measured ferritin levels within one month before transplantation who underwent ASCT with the diagnosis of MM or lymphoma were evaluated. The cut-off value of ferritin was determined as 500 ng/mL to evaluate the transplant outcomes in both groups. The hematological recovery status/duration, febrile neutropenia rate, hospitalization time, transplant-related mortality (TRM) in the first 100 days, and OS were evaluated according to the ferritin level RESULTS: Of all patients, 105 (61,8%) were diagnosed with MM and 65 (38.2%) with lymphoma. Ferritin levels had no statistically significant effect on the engraftment status/times, the febrile neutropenia rates, and hospitalization times of both lymphoma and myeloma patients (p > .05). Ferritin level was not significantly associated with TRM in MM (p = .224). However, in lymphoma, ferritin level was significantly associated with TRM (33.3% for ferritin level ≥500 ng/L vs. 5.3% for ferritin level ng/mL, p = .005). There was no statistically significant correlation between ferritin value and OS in MM group [ferritin level ≥ 500 ng/L: 39.9 months (95% CI: 33.7-46.1) and ferritin level 500 ng/mL: 39.4 months (95% CI: 36.5-42.2), p = .446]. Ferritin level was significantly associated with OS in patients with lymphoma [ferritin level ≥ 500 ng/L: 22.1 months 95% CI: 14.7-29.5), ferritin level 500 ng/mL: 27.3 months (95% CI: 22.4-32.2), p = .038] CONCLUSION: High ferritin level is important prognostic factor on survival after ASCT in patients with lymphoma.

Oral and post-transplantation infectious status in patients with hematopoietic stem cell transplants: A prospective observational study

OBJECTIVE

Infectious status may be life threatening in hematopoietic stem cell transplant (HSCT) recipients. The aim of this study was to evaluate the effect of oral status on infectious conditions during the neutropenic phase after HSCT.

STUDY DESIGN

Seventy patients with various hematologic malignancies were involved. Before HSCT, oral and periodontal examination, including the number of teeth and decayed, missing, and filled teeth index (DMFT); visible plaque (%); bleeding on probing (BOP [%]); clinical attachment level; and probing depth (PD) values were collected. Daily blood cultures were collected and analyzed in terms of infection-related parameters, including febrile neutropenia (FN), bacteremia, and C-reactive protein (CRP) during the neutropenic phase of HSCT.

RESULTS

Forty-two patients (60%) received autologous and 28 (40%) allogeneic HSCT. In both groups, patients without FN after HSCT had significantly lower DMFT index scores and fewer sites with PD ≥4 mm (P < .05). However, bacteremia, FN, and CRP were similar in patients with periodontitis compared with non-periodontitis patients (P > .05).

CONCLUSIONS

The results suggest that periodontal status may not significantly impact the infection-related parameters in patients treated for HSCT. However, DMFT and the prevalence of sites with PD ≥4 mm may be involved in febrile neutropenia.

Impact of periodontal status on the oral mucositis in patients receiving high-dose chemotherapy

OBJECTIVES

Oral mucositis (OM) is a frequent complication of cancer treatments. Oral mucositis and periodontal disease have a common inflammatory pattern. The purpose of this study was to evaluate the OM and its association with periodontal status in patients with hematologic malignancies who undergo high-dose chemotherapy.

MATERIALS AND METHODS

Fifty-five patients who received high-dose chemotherapy were included in the study. Full-mouth periodontal clinical measurements including plaque index (PI), gingival index (GI), clinical attachment level (CAL), and probing depth (PD) values were recorded before the condition chemotherapy regime. OM monitoring was initiated 1 day after the chemotherapy and maintained for 20 days.

RESULTS

Twenty-two of patients (40%) were observed oral mucositis after high-dose chemotherapy. Patients with mucositis had significantly higher GI scores than those who did not have mucositis (p < 0.05). There was a significantly moderate positive correlation between the grade of mucositis and GI scores (p < 0.05). In patients with periodontitis, the incidence of grade 1-2 mucositis was significantly higher than in the healthy group (p < 0.05). In individuals with periodontitis and gingivitis, the healing duration of mucositis was significantly longer than the healthy group (p < 0.05).

CONCLUSIONS

The results of this study showed that the severity grades of oral mucositis may increase in patients with gingival inflammation. The results also suggest that periodontal diseases may have a significant impact on the duration of oral mucositis.

CLINICAL RELEVANCE

The current study contributes to our understanding of the importance of oral health status in reducing the occurrence, severity, and duration of OM in hematological cancer patients treated with high-dose chemotherapy.

Early therapeutic plasma exchange may improve treatment outcomes in severe acute toxic Hepatitis

BACKGROUND AND OBJECTIVES

Acute toxic hepatitis can result in a different clinical course from a completely curable disease to subacute hepatitis, chronic hepatitis, and fulminant hepatitis failure, which is quite mortal. For this purpose, therapeutic plasma exchange (TPE) can be used for improving treatment outcomes by reducing the harmful substances caused with and/or without liver function in acute toxic hepatitis. We aimed to evaluate treatment outcomes in severe acute toxic hepatitis patients who applied early TPE procedure.

MATERIALS AND METHODS

A total of 335 patients who received TPE between 2010-2021 were retrospectively screened and 59 (male/female, 30/29; min/max-age, 22-84) patients with acute toxic hepatitis who underwent TPE in the first 24 h were included in the study. TPE was performed in patients who had high total bilirubin level (>10 mg/dL). Laboratory parameters of the patients before and after the TPE procedure, number of patients developed complications of acute toxic hepatitis and mortality rates were evaluated for effectiveness of TPE.

RESULTS

Acute toxic hepatitis was associated with hepatotoxic drugs in 44 (74.5 %), herbal medication 6 (10.2 %), mushroom poisoning 6 (10.2 %) and with substance abuse 3 (5.1 %) in patients. When the patients were compared based on INR, liver function tests, ammonia, lactate and Model For End-Stage Liver Disease (MELD) score at baseline, 48 h after TPE (independently of TPE number) and before final state a statistically significant decrease was observed in all parameters (p < 0.05). Fifty three (90 %) of patients improved without complications, the remaining 6 (10 %) patients were diagnosed with fulminant hepatitis. All these remaining patients died before liver transplantation (LTx) could be performed.

CONCLUSION

TPE is a safe, tolerable therapy option and early TPE may improve treatment outcomes in severe acute toxic hepatitis.

The effect of comorbidity on survival and collected CD34 + cell counts in autologous hematopoietic stem cell transplant patients

OBJECTIVE

In this study, we aimed to report the effectiveness of hematopoietic cell transplantation-specific comorbidity index (HCT-CI) and GATMO scores in predicting overall survival (OS) who underwent autologous stem cell transplantation (ASCT).

MATERIAL AND METHODS

The data of 263 MM and 204 lymphoma patients who underwent ASCT in the last 11 years were retrospectively analyzed.

RESULTS

Neutrophil engraftment time, thrombocyte engraftment time and collected CD34+ cell counts were similar in MM patients with HCT-CI>2 and HCT-CI≤2 (all p>0.05). Although the estimated median OS of MM patients with HCT-CI ≤2 tended to be higher than those with HCT-CI>2, this difference was not statistically significant (52.8 vs 45 months, p=0.172). No effect of GATMO score on CD34 + count, engraftment times and OS in MM patients was detected (p>0.05). The effect of HCT-CI score on lymphoma patients was examined, it was found that the neutrophil engraftment time was longer (p=0.039) and the number of collected CD34+ cells was lower (p=0.02) in patients with HCT-CI>2 than those with HCT-CI≤2. While the estimated median OS of lymphoma patients with HCT-CI≤2 was 51.5 months, the estimated median OS of patients with HCT-CI>2 was 9.5 months (p=0.012). When lymphoma patients were divided into four groups according to their GATMO scores, the OS of the four groups was found to be different from each other (p<0.001).

CONCLUSION

HCT-CI and GATMO scores predict OS in lymphoma patients but not MM patients.

Filgrastim alone versus cyclophosphamide and filgrastim for mobilization in multiple myeloma patients

BACKGROUND AND OBJECTIVE

High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is standard treatment approach in most multiple myeloma (MM) patients. Before ASCT, chemomobilization or only granulocyte-colony stimulating factor (G-CSF) mobilization can be preferred in stem cell mobilization. The primary aim of the study is to compare the effect of the two mobilization regimens on hematopoietic engraftment times, CD34+cell counts and number of apheresis required to harvest stem cells.

MATERIALS AND METHODS

The records of MM patients who applied to our hospital between 2010 and 2020 were analysed retrospectively. Patients were divided into two groups (Group A: Cyclophosphamide plus filgrastim, Group B: Filgrastim alone) according to the mobilization regimen.

RESULTS

A total of 223 MM patients were included in this study (Group A:153, Group B:70 patients). When the patients in Group A and Group B were compared, the number of collected CD34+ cells were higher in Group A (p < 0.001). However, there was no significant difference between the two groups in terms of median times to neutrophil and platelet engraftment, and number of apheresis required to harvest stem cells (p > 0.05). The rate of infection development during mobilization in the patients in group A and the duration of hospitalization of these patients were higher than the patients in group B (p < 0.001). Patients receiving >6 cycles of chemotherapy and immunomodulatory treatment had lower collected CD34+ cells than other patients (p = 0.012 and p = 0.054).

CONCLUSION

Based on our findings, filgrastim alone seems to provide a sufficient amount of stem cells in MM patients.

Lenograstim versus filgrastim in mobilization before autologous hematopoietic stem cell transplantation in patients with multiple myeloma and lymphoma - Single center experience

OBJECTIVE

Peripheral blood stem cell transplantation is frequently used in the treatment of various hematological malignancies after intensive chemotherapy. The primary aim of our study is to compare the amount of collected CD34+ cells and engraftment times in patients mobilized with filgrastim or lenograstim.

MATERIAL AND METHODS

Demographic and clinical data of multiple myeloma (MM) and lymphoma patients who underwent autologous transplantation and mobilized with G-CSF (filgrastim or lenograstim) without chemotherapy were collected retrospectively.

RESULTS

One hundred eleven MM and 58 lymphoma patients were included in the study. When mobilization with filgrastim and lenograstim was compared in MM patients, there was no significant difference in neutrophil and thrombocyte engraftment times of lenograstim and filgrastim groups (p = 0.931 p = 0.135, respectively). Similarly, the median number of CD34+ cells collected in patients receiving filgrastim and lenograstim was very similar (4.2 × 10⁶/kg vs 4.3 × 10⁶/kg, p = 0.977). When compared with patients who received lenalidomide before transplantation and patients who did not receive lenalidomide, the CD34+ counts of the two groups were similar. However, neutrophil and platelet engraftment times in the group not receiving lenalidomide tended to be shorter (p = 0.095 and p = 0.12, respectively). When lymphoma patients mobilized with filgrastim and lenograstim were compared, neutrophil engraftment time (p = 0.498), thrombocyte engraftment time (p = 0.184), collected CD34+ cell counts (p = 0.179) and mobilization success (p = 0.161) of the groups mobilized with filgrastim and lenograstim were similar.

CONCLUSION

The superiority of the two agents to each other could not be demonstrated. Multi-center prospective studies with larger numbers of patients are needed.

Life-saving effect of convalescent plasma treatment in covid-19 disease: Clinical trial from eastern Anatolia

Aim

Convalescent Plasma (CP) therapy is of interest as no vaccine or specific treatment is available for emerging viruses such as severe acute respiratory syndrome coronavirus 2 causing Covid-19. It was aimed to report the results of our patients who underwent CP in the treatment of Covid-19.

Methods

CP treatment was applied to 26 Covid-19 patients in intensive care unit who had quantitative reverse transcriptase–polymerase chain reaction positive Sars-Cov-2 infection. Plasma was collected at least 14 days after complete recovery from patients who had mild or moderate infection with Sars-Cov-2 infection. The collected CP (200cc) were applied to severe Covid-19 patients. Laboratory values of patients just before CP and after 7 days were compared.

Results

There were no statistically significant differences in leukocyte, neutrophil, lymphocyte, platelet, CRP, ferritin, LDH, ALT, AST, sO₂ and total bilirubin values just before and after 1 week of CP. A statistically significant difference was found between age and lymphocyte values of living and dying patients. The patients who died were determined to have older age (74,6 vs 61,85, p = 0,018) and more severe lymphopenia (0,47 vs 1,18, p = 0,001).

Conclusion

CP therapy has the potential to provide immediate and promising treatment options before specific vaccines and treatments are developed. In early stage Covid-19 patients who do not need mechanical ventilation, CP treatment may be a curative treatment option.

Serum Zinc Levels in Iron Deficient Women: A Case-Control Study

Since similar symptoms and findings can be seen in the deficiencies of both iron and zinc, we aimed to evaluate the serum zinc levels of women with iron deficiency anemia (IDA). This study was conducted with women with iron deficiency and a healthy control group. When serum zinc levels were compared, they were found to be lower in the IDA group, which was statistically significant. With the help of these studies, iron and zinc treatment instead of only iron replacement may be considered in cases of iron deficiency.

The levels of nitric oxide in megaloblastic anemia

OBJECTIVE

The purpose of this study was to investigate the relationship between nitric oxide degradation products (nitrate and nitrite) levels and megaloblastic anemia which is treated with cyalocobalamin.

METHODS

A total of 30 patients with megaloblastic anemia (16 Male, 14 Female) were included in the study. Cyanocobalamin was administered (1.000 µg/day intramuscularly) until the reticulocyte crisis occurred to the normal range. The control group consisted of 30 healthy subjects (15 Male, 15 Female). Nitric oxide levels were measured before treatment and compared with the values obtained during peak reticulocyte count.

RESULTS

Plasma direct nitrite, total nitrite and nitrate levels were 24,86±3,87, 60.56±7,01 and 36,02±5,24 in before treatment versus 15,48±3,05, 38,92±6,44 and 22,77±6,04 μmol/dl in after treatment, respectively. Plasma direct nitrite, total nitrite and nitrate levels were significantly lower in after treatment compared with the before treatment (p<0.001).

CONCLUSION

Nitric oxide levels are seen to increase in megaloblastic anemia. This study suggested that abnormalities in the nitric oxide levels in megaloblastic anemia are restored by vitamin B12 replacement therapy.

Rapid progression of acquired amegakaryocytic thrombocytopenia to myelodysplastic syndrome: case report

Acquired amegakaryocytic thrombocytopenia (AAT) is a rare disease characterized by severe thrombocytopenia due to selective reduction or absence of megakaryocytes in the bone marrow. More commonly, patients with AAT have additional hematologic abnormalities such as macrocytosis or dyserythropoiesis, abnormalities which may predict progression to aplastic anemia or myelodysplasia. A 52-year-old female was admitted to hospital with mucosal and gingival bleeding. Megakaryocytes were not seen on the bone marrow aspiration and biopsy. AAT was diagnosed. Although she was treated with immunosuppressive therapy including prednisolone and cyclosporine, her disease progressed to myelodysplastic syndrome. She died at the third month of diagnosis because of cerebral bleeding.

A rare syndrome that can easily be missed: May-Hegglin anomaly

May-Hegglin is a rare disease characterized by macrothrombocytopenia and presence of Döhle-like bodies in white cells. We present a patient treated with acute myeloid leukemia had pale-blue colored inclusion bodies assuming Döhle in his neutrophils.

Paroxysmal Nocturnal Haemoglobinuria in the Differential Diagnosis of Unresponsive Iron Deficiency Anemia: A Case Report

A 16-year-old male patient who was on oral iron treatment for iron deficiency anemia for the last one year was seen at the Haematology clinic with complaints of weakness, pallor, and jaundice. A complete blood count revealed Hb of 4.2 mmol/L, Hct of 0.14, and MCV of 76 fl. A blood smear showed 50% neutrophils, 40% lymphocytes, and 10% monocytes with anisocytosis, poikilocytosis, polichromasia in erythrocytes and normoblasts. Reticulocyte count was under 1%. There was a slight erythroid hyperplasia in the bone marrow aspiration. Biochemical examinations showed total bilirubin of 3.9 mg/dL, indirect bilirubin of 3.4 mg/dL, and lactate dehydrogenase (LDH) of 6085 U/L (220-450). In re-evaluating the history of the patient, he was seen to be complaining of dark discoloration of morning urine. Perl's reaction was found to be positive for hemosiderin in the urine sediment. Because Ham's test was positive, the levels of CD55, 58, and 59 proteins on erythrocyte membranes were found to be lower. The patient was started 32 mg of methylprednisolone and his anaemia was improved by the 14th day of treatment. When evaluating iron deficiency anemia resistant to iron supplementation, PNH should be kept in mind.
