ABSTRACT
Objective The objectives of this study were to determine the frequency of the clinical spectrum of diseases in patients with macrocytosis and to summarize the diagnostic evaluation of patients found to have macrocytosis on laboratory testing. Background This was a cross-sectional study that took place at the Department of Medicine in Combined Military Hospital, Rawalpindi, Pakistan, from January to June 2023. Methodology One hundred and five patients with macrocytosis with mean corpuscular volume (MCV) values > 100 fL (80 to 100 fL) were inducted as per inclusion and exclusion criteria. Informed consent was obtained from all patients. Complete blood counts (CBC), peripheral blood film, serum vitamin B12 levels, serum folate levels, renal function tests (RFTs), liver function tests (LFTs), and thyroid function tests (TFTs) were performed during the assessment. Results The commonest cause of macrocytosis was vitamin B12 deficiency followed by folate deficiency, combined vitamin B12 and folate deficiency, and other causes were also found in a few cases. Conclusion Serum vitamin B12 and folate deficiency are the most common preventable causes of macrocytosis.
ABSTRACT
Objective: To determine the frequency and patterns of bone marrow infiltration in non-Hodgkin lymphoma patients. METHODS: The cross-sectional study was conducted at the Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from April to October 2021, and comprised patients of either gender aged 20-80 years who had been diagnosed with non-Hodgkin lymphoma. Following assessment and as per standard protocol, bone marrow aspirate and trephine biopsy were done on all patients from the posterior superior iliac spine, and slides were prepared and assessed. Data was analysed using SPSS 25. RESULTS: Of the 100 patients, 67(67%) were males and 33(33%) were females. The overall mean age was 54.99±12 years, and mean duration of symptoms was 11.7±1.5 months. Diffuse large B-cell lymphoma was the commonest type 43(43%). Infiltration of marrow occurred in 38(38%) patients, with 12(12%) of them being cases of mantle cell lymphoma. The commonest infiltration pattern was diffuse in 17(17%) cases, followed by focal/nodular in 10(10%). CONCLUSIONS: Diffuse large B-cell lymphoma was found to be the commonest type of non-Hodgkin lymphoma, and marrow infiltration occurred most frequently in cases of mantle cell lymphoma.
