Brusellozisin Tetiklediği Herediter Sferositoz: Folik Asit Eksikliği, Hemolitik ve Megaloblastik Kriz

Year 2015, Volume: 9 Issue: 4, 280 - 282, 01.12.2015

Abstract

Herediter sferositoz kalıtsal hemolitik anemiler içinde en sık görülen hemolitik anemi nedenidir. Herediter sferositozu olan hastalarda nonspesifik enfeksiyonların (çoğunlukla viral) tetiklemesi ile hemolizin artması sonucu var olan anemi, sarılık ve splenomegali artar. Brusellozu olan hastalarda da anemi, sarılık ve splenomegali gelişebilir. Aynı klinik belirti ve bulguları gösteren herediter sferositoz ve brusellozis birbiri ile karışabilir. Bu nedenle brusellozun tetiklediğini düşündüğümüz, herediter sferositoz komplikasyonu (folik asit eksikliği, hemolitik ve megaloblastik kriz) gelişen bir hasta sunulmuştur. On altı yaşında erkek hastada baş ağrısı, terleme, solukluk, sarılık ve splenomegali vardı. Lökosit 7600/μL, Hb 11 g/dL, Hct % 27.1, trombosit 215.000 μ/L, MCV 92.2 fL, RDW %18.3, MHC 37.3pg, MHCH 40.7 g/dL retikülosit %8 (düzeltilmiş retikülosit %5)’di. Periferik yaymada çok sayıda makrosit ve mikrosferositler gözlendi. Haptoglobin ve folik asit düzeylerinde düşüklük, total bilirubin ve LDH düzeylerinde yükseklik, osmotik frajilitede artış tespit edildi. Brusella tüp aglitünasyonu 1/320 olarak bulundu. Hastaya folik asit, rifampisin ve doksitetrasiklin başlandı. Tedavi sonrası şikayetleri kaybolan, dalak boyutları küçülen hastanın folik asit düzeyi normale döndü.Herediter sferositoz belirti ve bulguları daha çok nonspesifik (viral) enfeksiyonların tetiklemesi ile açık hale gelmektedir. Özellikle brusellozisin endemik olduğu bölgelerde (folik asiti düşüklüğü, anemisi ve splenomegalisi bulunan hastalarda), herediter sferositozun spesifik bir tetikleyicisi olarak brusellozis de akla getirilmelidir.

Hereditary Spherocytosis Triggered by Brucellosis: Folic Acid Deficiency with Hemolytic and Megaloblastic Crisis

Year 2015, Volume: 9 Issue: 4, 280 - 282, 01.12.2015

Abstract

Hereditary spherocytosis is the most common hereditary hemolytic anemia. Anemia, jaundice and splenomegaly develop in hereditary spherocytosis patients as a result of the increased hemolysis following the triggering action of non-specific infections (mostly viral). Anemia, jaundice and splenomegaly may develop in patients with brucellosis as well. Hereditary spherocytosis can be confused with brucellosis as both have the same clinical signs and symptoms. We present a patient who developed hereditary hereditary spherocytosis (folic acid deficiency with hemolytic and megaloblastic crisis) that we believe was triggered by brucellosis. A 16-year-old patient presented with headache, sweating, pallor, jaundice and splenomegaly. Laboratory tests revealed a leukocyte count of 7600/µL, Hb 11 g/dL, Hct 27.1%, platelets 215,000 µ/L, MCV 92.2 fL, RDW 18.3%, MHC 37.3 pg, MHCH 40.7 g/dL, and reticulocytes 8% (corrected reticulocytes 5%). Peripheral blood smear showed a large number of macrocytes and micro-spherocytes. There was a decrease in haptoglobin and folic acid, increase in total bilirubin and LDH and increase in osmotic fragility. Brucella tube agglutination was 1/320. The patient was started folic acid, rifampicin and doxytetracycline. The symptoms disappeared, spleen dimensions regressed and the folic acid level returned to normal with treatment.In conclusion, the symptoms and signs of hereditary spherocytosis can become prominent with a triggering nonspecific infection (viral). Brucellosis should also be considered a specific trigger of hereditary spherocytosis (in patients with anemia, splenomegaly and low folic acid), especially in areas where brucellosis is endemic

The publication language of Turkish Journal of Pediatric Disease is English.


Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 10 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.


The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
