Scappaticcio L, Maiorino MI, Maio A, Esposito K, Bellastella G. Neutropenia in patients with hyperthyroidism: Systematic review and meta-analysis. Clin Endocrinol (Oxf) 2021; 94:473-483. [PMID: 32799342 DOI: 10.1111/cen.14313] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 08/09/2020] [Accepted: 08/10/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND AND OBJECTIVE Neutropenia, a low absolute neutrophil count (ANC), may be a sign of new-onset hyperthyroidism. The aim of this systematic review and meta-analysis was to provide the most reliable estimates of prevalence, degree and response to treatments of neutropenia in the pure hyperthyroidism setting. METHODS A comprehensive literature search was performed in PubMed and Scopus databases for retrieving articles in English and non-English languages reporting ANC values/neutropenic cases at presentation and after therapy in patients with hyperthyroidism. A proportion meta-analysis was performed with DerSimonian and Laird method (random-effects model). Pooled data were presented with 95% confidence intervals (95% CI) and displayed in a forest plot. I2 statistic index was used to quantify the heterogeneity among the studies. Sensitivity analyses for the prevalence of neutropenia and the mean of ANC in hyperthyroid patients were performed by excluding the studies without full details. Trim and fill analysis and Egger's linear regression test were carried out to evaluate the publication bias. A two-sided P-value of <.05 was regarded as significant for all analyses. The National Heart, Lung and Blood Institute Quality Assessment Tool was used to evaluate the quality of studies included. RESULTS The literature search yielded 1880 studies of which 13 studies were included for systematic review and meta-analysis. Results of the meta-analysis demonstrated that the prevalence of neutropenia in newly diagnosed and untreated patients with Graves' hyperthyroidism was 10% (CI 5%-19%, I2 88.6%) and summary mean ANC value in neutropenic was 1.4 ± 0.3 × 109 /L. In all neutropenic patients under ATD therapy neutropenia resolved, thus without the worsening of the baseline ANC values or the development of agranulocytosis. The sensitivity analyses showed similar results as those of the main analyses. For all outcomes, the publication bias was not statistically significant or not calculable. CONCLUSIONS Graves' disease per se is associated with neutropenia in about 10% of cases. Neutropenia usually appears as a mild to moderate laboratory abnormality with no detectable consequences. Subnormal/mild neutropenia should not be regarded as a contraindication to use ATDs, and clinicians should know that treating hyperthyroidism they have a significant chance to normalize ANC too.

Abstract
Graves' disease is an autoimmune disease that affects the thyroid glands which often results in enlarged thyroid glands, and it is the most common cause of clinical hyperthyroidism especially in young patients. Radioiodine ablation is a radiation therapy in which radioactive iodine is administered to destroy or ablate thyroid cells. It is commonly used for the treatment of Graves' disease. We report on a 39-year-old male, who presented with Graves' disease, found to have pancytopenia and hypocellular bone marrow. Pancytopenia is a rare complication of thyrotoxicosis that is usually not severe and does not require supportive blood product transfusions. Our patient was treated with antithyroid medications followed by radioactive iodine ablation followed by a spontaneous recovery of pancytopenia.

Can neutrophil/lymphocyte ratio be used as an indicator of inflammation in patients with hyperthyroidism? J Med Biochem 2020; 39:7-12. [PMID: 32549771 DOI: 10.2478/jomb-2019-0004] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Accepted: 01/23/2019] [Indexed: 01/02/2023] Open
Abstract
Background In our study, we aimed to evaluate changes in the neutrophil and lymphocyte series and investigate whether the neutrophil/lymphocyte ratio (NLR) is indicative of inflammations in patients with hyperthyroidism. Methods A total of 161 patients were enrolled, 121 of which had hyperthyroidism (71 Graves' Disease (GD) and 50 non-Graves hyperthyroidism (NGH) patients) and 40 of which were control group members. Retrospectively, patients' neutrophil and lymphocyte counts were taken, and the NLR was calculated. Results While the number of neutrophils was significantly lower in the GD group (p = 0.003), there was no significant difference between the NGH and the control group. In the GD group, NLR values were significantly lower than the other two groups (median 1.39 for GD, median 1.84 for NGH and median 1.83 for the control group, p < 0.001). Only three patients in the GD group had neutropenia. There was also a significant negative correlation between free T3 and neutrophil count and NLR in hyperthyroid patients (r = -0.28, p = 0.001 and r = -0.34, p < 0.001, respectively). Conclusions In our study, we found that NLR did not in crease in hyperthyroid patients and that this ratio decreased due to the decrease in neutrophil levels in GD. We thus concluded that NLR is not a suitable indicator of hyperthyroidism.

Abstract
Objective In rare instances, cytopenias manifest as a complication of thyrotoxicosis. Here, we report a case of Graves disease (GD) thyrotoxicosis presenting as pancytopenia that resolved with antithyroid therapy. Methods A 35-year-old male presented with fever and chills following an outpatient colonoscopy. Initial blood work revealed pancytopenia. Workup included viral antigen titers, blood cultures, rheumatologic antibodies, inflammatory markers, immunocompetency, nutrient deficiency, metal toxicity, and malignancy. Bone marrow aspirate was analyzed by microscope, flow cytometry, fluorescence in situ hybridization, and genetic analysis. Computed tomography scan of the chest, abdomen, and pelvis was obtained. Thyroid labs included thyroid-stimulating hormone, total triiodothyronine, free thyroxine, thyroid-stimulating immunoglobulin, anti-thyroid peroxidase antibody, and radioiodine uptake scan. Results All workup above was non-revelatory except as follows. Imaging revealed thymic hyperplasia and splenomegaly. Thyroid labs revealed thyroid-stimulating hormone <0.02 μIU/mL (reference range is 0.30 to 5.00 μIU/mL), free thyroxine of 4.7 ng/dL (reference range is 0.7 to 1.7 ng/dL), total triiodothyronine of 191 pg/mL (reference range is 90 to 180 pg/mL), thyroid-stimulating immunoglobulin of 522% (reference range is <140%). Bone marrow biopsy was consistent with a reactive process suggesting an infectious or autoimmune process. Radioiodine uptake scan confirmed GD. He was discharged on antithyroid medication. Two-month follow-up labs revealed improved cell counts; his absolute neutrophil count was 1.94 × 109 cells/L (reference range is 1.50 to 8.00 × 109 cells/L), hemoglobin was 12.9 g/dL (reference range is 14.0 to 17.0 g/dL), and platelets were 153 × 109 cells/L (reference range is 140 to 400 × 109 cells/L). Definitive treatment was obtained with 12 mCi of 131-iodine. Conclusion Pancytopenia and lymphoid organ hyperplasia (splenomegaly, thymic hyperplasia, and lymphadenopathy) have been previously reported to be associated with thyrotoxicosis secondary to GD, rarely simultaneously, and manifest from both thyrotoxic and immunologic mechanisms. After excluding alternative life-threatening pathologies, in such presentations, GD should be considered and treated if confirmed.

Abstract
CONTEXT Neutropenia secondary to antithyroid drug (ATD) therapy in Graves' disease (GD) is well recognized. However, the effect of hyperthyroidism, prior to and after ATD therapy, on neutrophil counts in patients with GD is unclear. OBJECTIVE To study the prevalence of neutropenia in newly diagnosed untreated GD and the effect of ATD on the neutrophil count. DESIGN Prospective study from August 2010 to December 2014. SETTING Endocrinology outpatient clinic in a single centre. PATIENTS Consecutive patients (n = 206) with newly diagnosed GD. INTERVENTION ATD therapy. MAIN OUTCOME MEASURES Prevalence and factors predicting neutropenia (<2 × 109 /l) and change in neutrophil counts following ATD. RESULTS At diagnosis, 29 (14·1%) of GD individuals had neutropenia. Non-Caucasians [odds ratio (95% CI) of 4·06 (1·14-14·45), P = 0·03] and patients with higher serum thyroid hormone levels [OR 1·07 (1·02-1·13), P = 0·002 for serum FT3] were the only independent predictors of neutropenia. All patients with neutropenia had normalized blood neutrophil levels after achieving euthyroidism with ATD therapy. In patients in whom data were available posteuthyroidism (n = 149), change in neutrophil count after achieving euthyroidism was independently related to reduction in thyroid hormone levels (P < 0·01). CONCLUSIONS GD is associated with neutropenia in one in seven patients at diagnosis, especially in non-Caucasians and those with higher serum thyroid hormone levels. Neutrophil counts increase with treatment with ATD and are related to reduction in thyroid hormone concentrations. It is therefore important to check neutrophil levels in newly diagnosed patients with GD prior to commencing ATD therapy as otherwise low levels may incorrectly be attributed to ATD therapy.

Abstract
Granulopoiesis abnormalities have been described in association with thyroid disorders (TD). However, data regarding systematic evaluation of adult neutropenia and concurrent or prior TD are scarce. To investigate the frequency of TD among patients presenting with neutropenia, and the immunophenotypic and immunologic profile of neutropenic patients with concomitant thyroidopathy. Two hundred eighteen consecutive neutropenic patients were prospectively evaluated in our outpatient Hematology Clinic, with a detailed laboratory screen, including thyroid function tests, antineutrophil antibodies, blood lymphocytes immunophenotyping, and detection of T-cell clonality by PCR. Among 218 patients with neutropenia, 95 (43.6%) had TD, 65 chronic immunologic neutropenia, 20 clonal proliferation of T-large granular lymphocytes (T-LGL), 5 autoimmune disorders, and 33 other diagnoses. TD-patients had an increased frequency of recurrent infections compared with other patients (P = 0.045). The following correlations were found: negative correlation between FT3 and absolute neutrophil count (ANC) (r² = -0.274, P = 0.007), negative correlation between TPO-Abs/TG-Abs and C4 (r² = -0.16, P = 0.045; r² = -0.266, P = 0.001), and CD4⁺ counts were inversely correlated to T4 and positively to TSH (r² = -0.274, P = 0.024; r² = 0.16, P = 0.045). In addition, TD-patients had significantly higher percentages of CD4⁺ lymphocytes (P = 0.003). Among TD-patients, 23.4% had Hashimoto thyroiditis (HT), 4.1%, Graves disease (GD), 8.2% nontoxic multinodular goiter (NTMG), 5% subclinical hypothyroidism, and 2.8% had undergone total thyroidectomy associated with nodules (TTM). Thirteen TD-patients displayed T-LGL. Patients with autoimmune thyroidopathy had an increased frequency of concomitant autoimmune manifestations (P = 0.03). Significant differences between the different thyroidopathies included: HT-patients had higher percentages of B-lymphocytes, while the opposite was evident for the TTM-subgroup (P = 0.009, 0.02); GD-patients showed an increase of the proportion of NK cells and a decrease in the percentage of TCRγδ+ lymphocytes (P = 0.001, 0.045); and NTMG-patients had significantly higher ANC (P = 0.004) compared to other thyroidopathies. Antineutrophil antibodies were found in 37.2% of TD-patients tested. Anti-TPO titers were significantly higher in patients with positive antineutrophil antibodies (P = 0.04). The frequency of TD among neutropenic patients may be higher than previously reported. The existence of antineutrophil antibodies, as well as the different distribution of lymphocyte subsets among patients with different TD, suggests both humoral and cellular mechanisms in the pathophysiology of thyroid disease-associated neutropenia.

Abstract
Background Pancytopenia is a rare complication of hyperthyroidism. Various mechanisms have been described such as immunological, bone marrow suppression. The possibility of hyperthyroidism should be considered in patients with unexplained pancytopenia. There are many case reports showing the association between hyperthyroidism and pancytopenia. All of these reports show association between Graves disease and pancytopenia but our case shows association between Multinodular goitre and pancytopenia. Besides it is uncommon to find such association in a surgical patient. Case presentation This case report describes a 62 yr old hindu female with splenic injury and pancytopenia. On further investigations the patient was found to have hyperthyroidism. Conclusion Though the definite mechanism regarding the association of pancytopenia with hyperthyroidism isn’t clear, various cases have been described in the literature. This case shows the diagnostic dilemma that can occur in patients with pancytopenia. Any patient with unexplained pancytopenia should undergo thyroid function tests to rule out hyperthyroidism.

Abstract
OBJECTIVE Changes in soluble intercellular adhesion molecule-1 (sICAM-1) and E-selectin levels as well as leukocyte count were examined in this study to explore the relationship between leukopenia and ICAMs in Graves' disease (GD). METHODS Fasting blood samples were obtained from 37 GD patients with normal leukocytes and 32 GD patients with leukopenia. Enzyme-linked immunosorbent assay (ELISA) was performed to determine serum sICAM-1 and E-selectin levels for comparison. The same analyses were repeated for the GD patients with leukopenia after glucocorticoid treatment (15 mg/day to 30 mg/day prednisone). RESULTS The ELISA results showed that E-selectin levels were higher in GD patients with leukopenia than those with normal leukocytes (p < 0.05), but these levels decreased after glucocorticoid (prednisone) treatment (p < 0.05). No significant change in sICAM-1 levels was observed (p = 0.12). Correlation analysis showed that leukocyte count and E-selectin were negatively correlated (r = -0.778; p < 0.05). CONCLUSION E-selectin may have an important function in GD with leukopenia, and glucocorticoids (prednisone) could decrease E-selectin level, which may be a new therapy target for GD with leukopenia.

Abstract
OBJECTIVES Thyroid hormones mediate many physiological and developmental functions in humans. The role of the 3,3',5-triiodo-L-thyronine (T3) in normal human haematopoiesis at the cellular and molecular levels has not been determined. In this study, it was revealed that the human haematopoietic system might be directly depended on T3 influence. MATERIALS AND METHODS We detected the TRalpha1 and TRbeta1 gene expression at the mRNA level in human cord blood, peripheral blood and bone marrow CD34(+)-enriched progenitor cells, using the RT-PCR method. Furthermore, we performed Western blotting to prove TRalpha1 and TRbeta1 expression occurs at the protein level in human cord blood, peripheral blood and bone marrow CD34(+) cells. In addition, the examined populations of cells were exposed in serum-free conditions to increasing doses of T3 and were subsequently investigated for clonogenic growth of granulocyte-macrophage colony-forming unit and erythrocyte burst-forming unit in methylcellulose cultures, and for the level of apoptosis, by employing annexin V staining and the terminal deoxynucleotidyltransferase-mediated dUTP nick-end labelling method. We investigated expression levels of apoptosis-related Bax and antiapoptotic Bcl-2 and Bcl-x(L) genes in the examined cells. RESULTS We found that exposure to higher and lower than normal concentration of thyroid hormone significantly influenced clonogenecity and induced apoptosis in human haematopoietic progenitor cells. CONCLUSIONS This study expands the understanding of the role of thyroid disorders in normal human haematopoiesis and indicates a direct influence of T3 on this process.

Abstract
The incidental discovery of neutropenia during routine blood counting represents a common problem for clinicians. However, there are no reported data of systematic evaluations of adults with incidental neutropenia. As such, this was the aim of the present study. Ninety-seven adults with incidental neutropenia were submitted to a clinical and laboratory approach including medical evaluation, complete blood count (CBC), serial CBC, direct and indirect antiglobulin test, bone marrow smear and biopsy, assessment of folate, vitamin B12 and iron status, serum liver enzymes, serum proteins, serological exams for hepatitis B and C virus, cytomegalovirus, mononucleosis, human immunodeficiency virus and toxoplasmosis, detection of lupus erythematosus cells, antinuclear and anti-DNA antibodies and rheumatoid factor, dosage of free thyroxin and thyrotropin, chest roentgenogram and abdominal echography. Chronic idiopathic neutropenia of adults was identified in 34.0% of the individuals, neutropenia due to exposure to chemical agents was seen in 16.5%, infectious diseases in 9.3%, autoimmune diseases in 9.3%, haematological diseases in 9.3%, thyroid disorders in 8.2%, ethnic neutropenia in 7.2%, drug-related neutropenia in 2.1%, cyclic neutropenia in 2.1% and iron deficiency in 2.1%. Recovery or improvement of the neutrophil count was seen upon treatment or recuperation from infectious, autoimmune, haematological and thyroid diseases and iron supplementation. We conclude that the evaluation of individuals with incidental neutropenia using a structured approach may make the identification of clinically silent diseases possible, and provide an opportunity for early treatment, avoiding complications of the diseases and consequences of neutropenia.

Abstract
Graves disease is a frequent cause (30-40%) of hyperthyroidism. In addition to the classic clinical triad (goiter, exophthalmos and tachycardia), symptoms relating to other organ systems may be found at presentation. Cutaneous manifestations play an important role and may initially be the only clue to the endocrine disorder. A 40-year-old woman with Graves disease presented with features of systemic lupus erythematosus. She had a malar rash, as well as marked hematological changes (thrombocytopenia and leukocytopenia) and antinuclear antibodies (1:640). She also had hyperthyroidism and Graves disease-specific thyroid autoantibodies (TSIg). Her symptoms improved after initiation of antithyroid therapy. Because of overlapping clinical and laboratory criteria, Graves disease can mimic systemic lupus erythematosus. The differentiation requires careful laboratory evaluation. Moreover, both autoimmune diseases may occur in the same patient.
