A rare case of complicated malaria presenting as warm autoimmune hemolytic anemia

Autoimmune hemolytic anemia (AIHA) has been rarely reported worldwide or from India as the underlying cause of anemia in malaria. We hereby present a case of complicated Plasmodium falciparum malaria with concomitant warm AIHA in a 31-year-old male. Direct Antiglobulin Test (DAT) was positive and elution studies showed pan-agglutination reaction. Clinico-hematological and serological follow-up of the patient was done post artesunate treatment until day 9. We suggest that it is important to establish the immune basis of anemia in malaria patients for guiding the treatment plan for the clinicians and providing packed red blood cell transfusion if required.

Dual pathogen valvular endocarditis in a case of severe aortic aneurysm

ABSTRACT Infective endocarditis (IE) is the heart valve or endocardium infection. We report a rare case of polymicrobial endocarditis, namely invasive Aspergillus spp and Acinetobacter baumannii, in a 36-year-old male with a medical history of degenerative disease of the aorta with abdominal aortic and ascending aortic aneurysms with a fulminant clinical course and fatal outcome. The treatment was challenging due to multiple comorbidities. The autopsy revealed dual pathogen endocarditis due to Acinetobacter baumannii sepsis and invasive Aspergillus spp mycosis. This report emphasizes that polymicrobial endocarditis (PE) is an infrequent finding with a poor prognosis requiring high clinical suspicion.

Primary Ewing sarcoma/primitive neuroectodermal tumor of the lung

We present the autopsy findings and differential diagnosis in a 42year old male who presented with fever and rapidly progressive respiratory symptoms like breathlessness, nonproductive cough and right sided chest pain. Initial imaging workup done at our hospital revealed a large unilateral tumor with tracheal shift. While being evaluated patient developed facial puffiness, tachypnea suggestive of superior vena cava obstruction. Antemortem biopsy of lung mass was attempted twice and that suggested malignant lesion. Unfortunately, the individual had a rapid downhill course following admission. Post mortem examination was conducted that on opening the thoracic cavity revealed total replacement of right lung tissue by a necrotic growth which was deeply adherent to the rib cage. The contralateral lung as well as all other visceral organs were unremarkable grossly. Histopathology confirmed primary Ewing sarcoma of the lung. We hereby, report a rare case of primary lung Ewing sarcoma diagnosed at autopsy.

Therapy-related acute promyelocytic leukemia after treatment of carcinoma breast--a case report.

We report a 43-year-old female, with acute promyelocytic leukemia occurring after 9 months of treatment for carcinoma breast. The diagnosis of APL was made on morphology, cytogenetics and molecular studies. In contrast to other published report of therapy related APL (tAPL) the present case presented early after the primary malignancy and underwent a rapid, downhill course.

Role of MTHFR C677T polymorphism in ischemic stroke.

BACKGROUND: Homozygosity for MTHFR C677T polymorphism can lead to significantly high homocysteine levels and hyperhomocysteinemia is an important risk factor for thrombotic events. AIMS: The aim was to determine role of MTHFR C677T polymorphism in North Indians with ischemic stroke. SETTINGS AND DESIGN: In a prospective study, the subjects of stroke were recruited from the neurology clinic of the hospital. Controls were healthy individuals from the Hematology clinic without any history of stroke. MATERIALS AND METHODS: Plasma homocysteine levels were measured by enzyme immuno assay method after 3 months of acute episode. Serum folate and Vitamin B12 levels were estimated by competitive inhibition radioassay. MTHFR polymorphism was detected by PCR-RFLP using Hinf I enzyme. Statistical analysis: The analysis of significance of results was done using SPSS software package. A p-value. RESULTS: Thirty-two acute ischemic stroke patients (aged 1-44 years) were studied. Fourteen (43.8%) had recurrent stroke. Nine (28%) had multiple infarcts. Four of 32 patients (12.5%) had high homocysteine levels. Three out of these 4 hyper-homocysteinemia patients were homozygous ( TT ) for MTHFR polymorphism (2 with recurrent stroke). Two of three homozygous cases with TT genotype had low serum folate. Five of 32 stroke cases (18.8%) were heterozygous ( CT ) genotype. CONCLUSIONS: Primary hyper-homocysteinemia appears to be an important risk factor for ischemic stroke in North Indians, most due to MTHFR C677T homozygosity. Folate levels may modify the presentation of the MTHFR TT genotype.

Gel card in the diagnosis of autoimmune haemolytic anemia.

The diagnosis of autoimmune haemolytic anaemia (AIHA) requires the establishment of haemolysis and demonstration of autoantibodies against red cells. Most laboratories use the conventional Coomb's test for the demonstration of the autoantibodies. However, in approximately 2-6% of the patients who present with the clinical and haematological features of AIHA, the direct agglutination test is negative on repeated testing. Attempts are therefore being made to identify a test which could be more sensitive than the conventional test, yet retaining the simplicity and cost effectiveness of the test. In the present study, the efficacy of the newly developed gel card test has been compared with the conventional Coomb's test for detection of autoantibodies in 50 cases clinically suspected to have haemolytic anemia. The gel card picked up the antibodies in all the cases detected to be positive by the conventional test. In addition, the gel card also picked up 5 tests which were negative by the conventional method. The sensitivity and specificity of the gel card Direct Coomb's test (DCT) as compared to the conventional tube test for DCT was found to be 100% and 95.1% respectively. The Indirect Coomb's test (ICT) was 100% sensitive and 92.5% specific. In view of the high sensitivity and specificity and the simplicity of the procedure, this test may be effectively used for diagnosis of AIHA.
