Stroke incidence, mortality, subtypes in rural and urban populations in five geographic areas of India (2018-2019): results from the National Stroke Registry Programme.

Background: Increasing stroke burden in India demands a long-term stroke surveillance framework. Earlier studies in India were urban-based, short term and provided limited data on stroke incidence and its outcomes. This gap is addressed by the establishment of five population-based stroke registries (PBSRs) of the National Stroke Registry Programme, India. This paper describes stroke incidence, mortality and age, sex, and subtypes distribution in the five PBSRs with urban and rural populations. Methods: First-ever incident stroke patients in age group ≥18 years, resident for at least one year in the defined geographic area, identified from health facilities were registered. Death records with stroke as the cause of death from the Civil Registration System (CRS) were included. Transient ischemic attack (TIA) was excluded. Three PBSRs (Cuttack, Tirunelveli, Cachar) included urban and rural populations. PBSRs in Kota and Varanasi were urban areas. The crude and age-standardized incidence rate (ASR) by age, sex, and residence (urban and rural), rate ratios of ASR, case fatality proportions and rates at day 28 after onset of stroke were calculated for years 2018-2019. Findings: A total of 13,820 registered first-ever stroke cases that included 985 death certificate-only cases (DCOs) were analysed. The pooled crude incidence rate was 138.1 per 100,000 population with an age-standardized incidence rate (ASR) of 103.4 (both sexes), 125.7 (males) and 80.8 (females). The risk of stroke among rural residents was one in seven (Cuttack), one in nine (Tirunelveli), and one in 15 (Cachar). Ischemic stroke was the most common type in all PBSRs. Age-standardized case fatality rates (ASCFR) per 100,000 population for pooled PBSRs was 30.0 (males) and 18.8 (females), and the rate ratio (M/F) ranged from 1.2 (Cuttack) to 2.0 (Cachar). Interpretation: Population-based registries have provided a comprehensive stroke surveillance platform to measure stroke burden and outcomes by age, sex, residence and subtype across India. The rural-urban pattern of stroke incidence and mortality shall guide health policy and programme planning to strengthen stroke prevention and treatment measures in India. Funding: The National Stroke Registry Programme is funded through the intramural funding of the Indian Council of Medical Research, Department of Health Research, Ministry of Health and Family Welfare, India.

Diabetic striatopathy in an adult with ketotic hyperglycaemia.

Diabetic striatopathy (DS) is a rare and life-threatening mani- festation of diabetes. The disease commonly affects individuals of Asian descent, women and the elderly. DS is characterized by dyskinesias with basal ganglia hyperintensities on imaging. Despite being rare, prompt recognition of a hyperglycaemia- induced hemichorea-hemiballismus is essential because the symptoms are reversible with correction of hyperglycaemia. Diagnosis is based on blood analysis and neuroimaging findings. Laboratory tests reveal raised glycosylated haemoglobin (HbA1c) levels, which indicate poorly controlled diabetes. Neuroimaging provides suggestive findings of DS. It is usually associated with non-ketotic hyperglycaemia. We report a 50-year-old woman who presented with ketotic hyperglycaemia and left-sided hemichorea and partial seizures with secondary generalization.

Study of Mutations in ß-Thalassemia Trait among Blood Donors in Eastern Uttar Pradesh.

BACKGROUND: Knowledge on distribution of different mutations of thalassaemia, which are prevalent in a particular area, is a prerequisite for prenatal diagnosis. OBJECTIVES: Studying mutations in ß - thalassaemia trait among blood donors in eastern Uttar Pradesh, India. MATERIAL AND METHODS: One thousand non - remunerated voluntary blood donors who were between 18 - 40 years of age, were included in the study. Both replacement and voluntary healthy blood donors were included. 4ml of venous blood was collected and it was stored at 4°C. Complete Blood Count (CBC), Haemoglobinopathy Screening and Molecular Analysis by ARMS - PCR (Amplification Refractory Mutation System - PCR) were done. Screening for ß thalassaemia was done in a blood bank by using D - 10, Bio Rad, which was based on High Performance Liquid Chromatography (HPLC). RESULTS: Twenty Eight subjects with ß- thalassaemia trait were found among 1000 voluntary blood donors. IVS 1-5 (G-C) mutation was most common type (50%), followed by FS 8/9 (+G) 25% which was the second most common type. In our study, a rare mutation of CD 16 (-C) was also found. Out of 14 subjects who had IVS 1-5 (G-C) mutation (most common), six were from Varanasi (6/261) and five of them were Sindhis. It was seen that FS 41/42 (TCTT) mutation was distributed among all groups of populations which had higher prevalences of ß-thalassaemia trait. CONCLUSION: A comprehensive knowledge on beta thalassaemia mutations is necessary for determining a prenatal diagnosis. The occurrence of mutations may vary according to geographic region. Therefore, this study dealt with current problem of unknown mutations, in order to avoid complications.

Clinical profile and response to first-line ARV in HIV patients from Eastern UP and Bihar: a retrospective study.

BACKGROUND AND OBJECTIVES: Spectrum of infections in Human Immunodeficiency Virus (HIV) infected patient from Eastern UP and Bihar has not been systemically evaluated. This study was conducted with the following objectives; a) explore the spectrum of clinical conditions associated with HIV disease, b)the difference between clinical and investigatory parameters in those patients who presented with infection from those who present without infection and c) to evaluate the effect of anti-retroviral (ARV) therapy. METHODS: 1248 subjects who fulfilled the inclusion criteria were enrolled for the study from May 2007 to November 2008. Patients were evaluated for their baseline characteristics along with CD4 count and followed up for at least for 6 months after initiation of ARV (6-24 months). RESULT AND INTERPRETATION: In this retrospective study, tuberculosis (58.96%) was the commonest infection followed by chronic diarrhoea (26.56%) and various skin infections. Males had significantly higher incidence (p value < .001) of infection as compared to females. There was a significant difference between the patients who presented with infection from those who presented without infection for their baseline weight (42.3 vs 45.42), haemoglobin (9.06 vs 9.91), mean CD4 count at baseline (107.38 vs 128.38/microL) and CD4 count after 6 month of therapy (298.09 vs 322.98/microL). Mortality was also significantly high (p value < 0.05) in those who presented with infection (19.95% vs 15.1%), although there was no difference between these two groups on their improvement in CD4 count from baseline after 6 months of therapy. CONCLUSION: Among the spectrum of infection in HIV patient from North East part of India, tuberculosis was commonest, followed by skin infections and chronic diarrhoea. Patients who presented with infection at the time of initial presentation had a low haemoglobin, body weight and CD4 count and had high initial mortality but if they survived they show similar response to ARV therapy as patients who presented without infection.

Assessment of left ventricular diastolic dysfunction in sub-clinical hypothyroidism.

BACKGROUND: Adverse cardiovascular effect of hypothyroidism has been identified in many studies. Early identification of patients with sub-clinical hypothyroidism may lead to early treatment and thereby favourable effect on cardiovascular morbidity and mortality. OBJECTIVES: To find out the association of sub clinical hypothyroidism and left ventricular dysfunction and also to find out relationship between systolic and diastolic dysfunction in these patients. MATERIAL AND METHODS: A total 30 cases of sub clinical hypothyroidism along with 15 age sex matched healthy control subjects were included in study. Serum TSH, T4, T3 hormone level was measured and those who were found to have sub-clinical hypothyroidism underwent for 2DEcho. RESULTS: Significant reduction in peak early filling velocity (PE) (p<0.001) and early filling time velocity integral (Ei) (p<0.001). Ratio of early and late peak velocities (PE/PA) (p<0.001), ratio of time velocity integral of early and atrial filling (Ei/Ai) (p<0.001) and ratio of the early peak to average velocity (PE/M) (p<0.001) were also reduced. Mean EF was 54.9± 5.55 as compared to 55.7 ± 3.46 of control subjects with a T.value of 0.48 ,however there was significant diastolic dysfunction in case of hypothyroid patients (mean Ei/Ai = 1.35 ± 0.53) as compared to control group subjects (mean Ei/AI = 2.11 ± 0.26) with a T value of 5.22. CONCLUSION: Sub-clinical hypothyroidism showed significant diastolic dysfunction in the absence of significant impairment of systolic function.

Endocrine changes in male HIV patients.

AIMS AND OBJECTIVES: To determine the frequency of adrenal, thyroid and gonadal dysfunction in HIV positive male patients and to evaluate the endocrine function at different level of CD4 cell counts. MATERIAL AND METHODS: A total of 150 male HIV positive subjects were included in study. The patients were divided in three groups on the basis of CD4 cell counts. "Group A": HIV positive with CD4 count<200/mm "Group B": HIV positive with CD4 count 200-350/mm3 and "Group C": HIV positive with CD4 count>350/mm3. RESULTS: In "group A" (n=50) 2 patients had basal cortisol<5 microg/dl while 23 patients had basal cortisol>25 microg/ dl. 15 patients had subclinical hypothyroidism while 11 patients had overt hypothyroidism. 25 patients in this group had gonadal dysfunction: majority of them (24) had primary gonadal dysfunction (elevated LH). None of the patients in "group B" (n=50) had hypocortisolism while 11 patients had elevated cortisol; 18 had subclinical hypothyroidism while 4 had overt hypothyroidism while 17 patients were hypogonad, all having elevated LH. In "group C" (n=50) 2 patients had hypocortisolism and 5 had elevated cortisol; 12 patients had subclinical and one had overt hypothyroidism; 7 patients had primary hypogonadism and one had secondary hypogonadism. Overall 4(2.66%) had hypocortisolism while 39 (26%) had elevated cortisol; 45 (30%) had subclinical hypothyroidism while 16(10.66%) had overt hypothyroidism. Gonadal dysfunction was observed in 50 patients (33%) majority of them (48) had primary hypogonadism. On analysis of Pearson's correlation coefficient CD4 count has strong inverse correlation with basal cortisol (r=-0.301, p<0.0001), TSH (r=-0.257, p=0.002) and LH (r=-0.228, p=0.006), while there was a direct correlation with serum testosterone (r=0.175, p=0.037). CONCLUSION: This pilot study has demonstrated a high incidence of endocrine dysfunction in HIV infected patient in this part of country. High incidence of thyroid and gonadal dysfunction may contribute to morbidity of the patients and have a bearing on quality of life of the HIV infected patients. Hypocortisolism was not that common but high level of cortisol may be a marker of stress due to HIV per se or due to associated infection. Many of these dysfunctions might be transient and a large longitudinal study should be undertaken to substantiate the finding of the present study.
