Background: The aim of this study was to evaluate the prevalence of thyroid abnormalities in a subset of human immunodeficiency virus positive patients.Methods: This was a cross-sectional prevalence study conducted on adult HIV positive patients. The patients presenting with hypertension, diabetes mellitus, coronary artery disease or thyroid disorder were excluded from the study. An exhaustive medical history and investigation using biochemical, microbiological and radiological tests were performed to confirm the diagnosis. Additionally, tests were done to determine the free T3, T4, thyroid stimulating hormone and CD4 cell count in all the patients.Results: The prevalence of thyroid dysfunction in our study was 45.7%. Various types of thyroid dysfunctions obtained were euthyroid sick syndrome in 18.6%, subclinical hypothyroidism in 11.4%, secondary hypothyroidism in 10% and primary hypothyroidism and hyperthyroidism each in 2.9% cases. As the stage of HIV advanced, there is alteration in the level of thyroid stimulating hormone, FT3 and FT4. A direct correlation was found between FT3 and CD4 counts but no correlation was found between thyroid stimulating hormone and FT4 levels and CD4 counts.Conclusions: A higher prevalence of thyroid dysfunction that was largely asymptomatic was observed in HIV infected patients with significant change in the hormonal levels in patients with low CD4 count. A direct correlation was observed between FT3 hormone level and CD4 count.

Aims: Pancytopenia is a common clinic-haematological problem suspected in patients with anaemia, prolonged fever, and a bleeding tendency.  This study was performed to find the prevalence of pancytopenia and to determine the common causes of pancytopenia. Study Design:  Cross-sectional observational study. Place and Duration of Study: department of general medicine at R. D. Gardi Medical College, Ujjain, India between November 2017 toAugust 2019. Methodology: The study was conducted among patients with pancytopenia during a two-year period. The etiological pattern was assessed through routine blood tests to determine their clinical features, peripheral blood pictures, and bone marrow morphologies. Results: Out of 100 patients with pancytopenia, the majority (64.0%) were men. A total of 34 patients were aged between the 21 and 30 years and 28 were aged between 31 and 40 years. Generalized weakness was the most common (88%) presentation and the most common clinical finding was pallor (94.0%), followed by splenomegaly (40.0%) and hepatomegaly (30.0%). Megaloblastic anaemia was the most common cause of pancytopenia that was observed in 58 patients, followed by aplastic anaemia (n=12), cirrhosis of the liver (n=8), leukaemia (n=6), dengue, myelodysplastic syndrome, and malaria (n=4 each), paroxysmal nocturnal haemoglobinuria and acquired immunodeficiency syndrome (n=2 each). A total of 28.0% patients had normocellular bone marrow and 72.0% had cellular marrow. Conclusion: Megaloblastic anaemia was the most common aetiology of pancytopenia.
