Platelet volume indices in patients with coronary artery disease and acute myocardial infarction: an Indian scenario.

AIMS: To study platelet volume indices (PVI) in the spectrum of ischaemic heart diseases. METHODS: A total of 210 cases were studied; 94 patients had unstable angina (UA) or acute myocardial infarction (AMI) diagnosed on the basis of history, characteristic electrocardiographic changes, and increased cardiac enzyme activities. Seventy patients had stable coronary artery disease (stable CAD) or were admitted for a coronary angiography or coronary artery bypass graft procedure. The third group comprised 30 age and sex matched healthy controls with no history of heart disease and a normal electrocardiogram. RESULTS: All PVI-mean platelet volume (MPV), platelet distribution width (PDW), and platelet large cell ratio (P-LCR)-were significantly raised in patients with AMI and UA (mean MPV, 10.43 (SD, 1.03) fL; mean PDW, 13.19 (SD, 2.34) fL; mean P-LCR, 29.4% (SD, 7.38%)) compared with those with stable CAD (mean MPV, 9.37 (SD, 0.99) fL; mean PDW, 11.35 (SD, 1.95) fL; mean P-LCR, 22.55% (SD, 6.65%)) and the control group (mean MPV, 9.2 (SD, 0.91) fL; mean PDW, 10.75 (SD, l.42) fL; mean P-LCR, 20.65% (SD, 6.14%)). CONCLUSIONS: Larger platelets are haemostatically more active and are a risk factor for developing coronary thrombosis, leading to myocardial infarction. Patients with larger platelets can easily be identified during routine haematological analysis and could possibly benefit from preventive treatment. Thus, PVI are an important, simple, effortless, and cost effective tool that should be used and explored extensively, especially in countries such as India, for predicting the possibility of impending acute events.

Profile of bone marrow examination in HIV/AIDS patients to detect opportunistic infections, especially tuberculosis.

Morphological evaluation of 140 bone marrow aspirations received in haematopathology laboratory with serologically established HIV infection, along with other relevant special haematological tests, was done during 1st Jan 1999 - 31st Dec 2002 at state government run tertiary care General Hospital in Maharashtra state, India. Out of 140 cases: 118 (84.28%) patients had anaemia, 25 (17.86%) had leukopenia, while 13 (9.28%) were thrombocytopenic. Dyserythropoiesis was present in 18 (12.86%) cases, dysmyelopoiesis 37 (26.43%) and micromegakaryocytes were noted in 44 (31.43%) cases. Haemophagocytosis was evident in 8 (5.71%) cases. Plasmacytosis encountered in 120 (85.71%) cases was a common feature. Based on clinical profile and results of other investigations 56 (40%) patients were clinically diagnosed to be of Mycobacterium tuberculosis (TB). Of these, 18 (12.86%) bone marrow aspirates were positive for AFB, Mycobacterium tuberculosis. In 4 cases cryptococci were demonstrated (Mucicarmine stain). There was one case each of Histoplasma capsulatum and leishmaniasis. One patient showed dense parasitemia with Plasmodium falciparum. One patient had immunoblastic lymphoma and showed bone marrow infiltration. Findings in this study strongly indicate that in HIV/AIDS, AFB stain should be done on each marrow aspirate to rule out tuberculosis in countries like India; where TB and AIDS are marching together.

Vasculitis with digital gangrene in a patient with HIV infection.

A case of polyarteritis nodosa (PAN) like systemic necrotizing vasculitis in an HIV infected individual, who presented with digital ischaemia is reported. The pathogenesis of PAN in HIV infected patients is not well understood and whether HIV or other agents are directly involved in the vascular injury remains to be established.

Evaluation of clinical criteria for the diagnosis of leptospirosis.

OBJECTIVES: Leptospirosis has a wide range of clinical presentation and therefore, clinical suspicion of the infection is often difficult. The objective of this study is to find out the usefulness of the clinical and epidemiological criteria in the diagnosis of leptospirosis and its comparison with microagglutination test (MAT). METHODS: A total of 118 patients with undiagnosed fever of more than seven days duration were included in the study. Their clinical presentation was scored on the basis of a clinical criteria. Sera of the patients were tested for antibodies against leptospira with the help of microagglutination test using a battery of antigens. The usefulness of the criteria was evaluated and compared with microagglutination test. RESULTS: A total of 44 out of 118 (37.28%) patients could be provisionally diagnosed as cases of leptospirosis on the basis of the clinical criteria. Eighteen of these 44 (40.9%) patients had serological evidence of leptospirosis. The criteria had a sensitivity of 81.81%, specificity of 72.91%, a positive predictive value of 40.9% and a negative predictive value of 94.59% when compared with microagglutination test. CONCLUSIONS: The criteria had a moderate sensitivity and specificity. Considering the non-specific signs and symptoms of this infection, the positive predictive value is significantly high. The criteria has a high negative predictive value and this would help the clinicians exclude the diagnosis of leptospirosis with precision.
