Role of Vitamin-D in the prevention and treatment of Alzheimer's disease.

Alzheimer's disease is the most common form of age related cognitive impairment. Aim of the present study was to see the effect of vitamin D on cognitive function in elderly. The study was conducted in Department of Physiology, King George's Medical University (KGMU). A total of 80 subjects were enrolled based on Mini Mental State Examination (MMSE) score < 24 and vitamin D deficiency. They were divided into two groups as Group A (case) and Group B (control), each group having 40 subjects. Intervention (Vitamin D supplementation) was given in Group A. The assessment of dementia was done by Mini Mental State Examination (MMSE) score. Every subject was clinically evaluated and estimation of vitamin D was done by direct ELISA kit. Gender, weight, height, BMI, residence and education were also similar between two groups. A significant (p=0.0001) change in MMSE score was observed in both Group A and Group B from baseline to 3 & 6 months and from 3 to 6 months, however, mean change was higher in Group A than Group B. In conclusion, vitamin D supplementation caused significant improvement in the cognitive performance in subjects with senile dementia.

HIV associated renal disease: a pilot study from north India.

BACKGROUND & OBJECTIVES: HIV/AIDS patients may have renal involvement also, however, Indian data are sparse. The present study was done to find the spectrum of renal diseases in HIV/AIDS patients in north India. METHODS: In this prospective pilot study, HIV positive patients aged >18 yr were screened for renal involvement [serum creatinine >1.5 mg% and/or significant proteinuria (>500 mg /day)]. Patients who were positive on screening were followed up prospectively and underwent kidney biopsy if indicated. RESULTS: A total of 526 patients were screened, of these, 91 (17.3%) were found to have renal involvement. Group A (Treatment naοve) comprised 392 patients who were not on antiretroviral treatment (ART) and group B (patients on ART) comprised 134 patients. More patients (74/392, 18.9%) in group A had renal involvement as compared to patients in group B (17/134, 12.7%). Of the 91 patients with renal involvement, 26 were followed up and underwent kidney biopsy. Thirteen patients had only proteinuria and another 13 had renal dysfunction with or without proteinuria. Most common histological diagnosis was mesangioproliferative glomerulonephritis (mes PGN) (10/26). Two patients had collapsing FSGS (focal segmental glomerulosclerosis) and three patients had immune complex glomerulonephritis. Seven patients had acute kidney injury, whom six totally recovered from their renal function. All patients with mesPGN tolerated angiotensin converting enzyme (ACE) inhibitors well. There was mixed response of collapsing FSGS to steroids. Both patients with MPGN (membranoproliferative glomerulonephritis) did well on low dose of steroid and ART. INTERPRETATION & CONCLUSIONS: Renal involvement was found to be common in HIV positive patients (17.3%). A low occurrence of renal involvement found in patients already on ART suggests some renoprotective effect of ART. Our preliminary results showed that collapsing FSGS was not rare in Indian HIV positive population, but classical HIV associated nephropathy was not seen. Longitudinal studies with robust study design and large sample size need to be done to confirm the findings.

Prevalence of psychiatric morbidity amongst the community dwelling rural older adults in northern India.

BACKGROUND & OBJECTIVES: The population of elderly is growing globally and so are the physical illnesses and psychiatric morbidity. This study was planned to assess the prevalence and patterns of psychiatric morbidity amongst rural older adults in Lucknow, north India. METHODS: A survey was conducted in subjects aged 60 yr and above to identify the cases of psychiatric morbidity in rural population from randomly selected two revenue blocks of Lucknow district, Uttar Pradesh, India. All subjects were screened through Hindi Mental Status Examination (HMSE) and Survey Psychiatric Assessment Schedule (SPAS) to identify for the suspected cases of cognitive and the psychiatric disorders, respectively. The subjects screened positive on HMSE and SPAS were assessed in detail on Cambridge Mental Disorder of the Elderly Examination-Revised (CAMDEX-R) and Schedule for Clinical Assessment in Neuropsychiatry (SCAN), to diagnose cognitive disorders and psychiatric disorders (other than the cognitive), respectively on the basis of International Classification of Diseases-10 (ICD-10) diagnostic guidelines. RESULTS: The overall prevalence of psychiatric morbidity in rural older adults was found to be 23.7 per cent (95% CI=21.89-25.53). Mood (affective) disorders were the commonest (7.6%, 95% CI=6.51-8.80), followed by mild cognitive impairment (4.6%, 95% CI=3.72-5.53), mental and behavioural disorders due to substance use (4.0%, 95% CI=3.17-4.87) and dementia (2.8%) [Alzheimer's disease (2.4%, 95% CI=1.81-3.16) and vascular (0.4%, 95% CI=0.16-0.73)]. INTERPRETATION & CONCLUSIONS: Overall prevalence of psychiatric morbidity amongst rural elderly in this study was found to be less in comparison to those reported in earlier studies from India. However, prevalence pattern of different disorders was found to be similar. Therefore, it appears that a stringent methodology, refined case criteria for diagnosis and assessment by trained professionals restrict false diagnosis.

Factors associated with low birth weight among newborns in an urban slum community in Bhopal.

A community based cohort study on birth weight of newborns was conducted among pregnant women of an urban slum in Bhupal, India. The study was carried out to assess the magnitude of low birth weight (LBW) and factors contributing it in an urban slum community. Socio-demographic and maternal characteristics were examined applying statistical techniques to find out the variables associated with the LBW. An additional schedule was used to collect information from mothers about their socio-demographic background, dietary intake and the rest during the pregnancy. Weight of newborns of mothers registered in the study and delivering at the district hospital was recorded. Mean birth weight of newborns of 290 registered mothers was 2.57 ± 0.36 g. One hundred and five newborns (36.2%) had a birth weight lesser than 2500 g. Among different variables studied, statistically significant association was found in case of occupation, daily calorie intake and duration of day-time rest taken by pregnant women.

Development of Comprehensive Satisfaction Index (ComSI) and Its Association with WHOQOL-BREF.

BACKGROUND: Comprehensive satisfaction in life may be considered as a significant contributor to health for everyone, including the aging population (individuals aged 45 years and above). For understanding the comprehensive satisfaction, an assessment measure with various psychometric properties may be useful. During a longitudinal study of aging and geriatric mental health, a 26-item tool was developed in Hindi for the assessment of satisfaction. This article aimed to analyze the items of Comprehensive Satisfaction Index (ComSI) applying Varimax rotation and to find out its association with World Health Organization Quality of Life Brief (WHOQOL-BREF). METHODS: Data of 260 subjects were extracted from the longitudinal study to analyze the psychometric properties of the tool named as Comprehensive Satisfaction Index and its association with various domains of WHOQOL-BREF. Varimax rotation was applied after computing Kaiser-Meyer-Olkin and Bartlett's test of sphericity. Furthermore, the association between various components of ComSI and various domains of WHOQOL-BREF was explored. RESULTS: Of the total 26 items of the tool, item no. 17 was excluded due to its -ve/ <0.31 value. A total of three components were generated with >1 eigenvalues; maximum items were loaded in component 1 (19) followed by components 2 (4) and 3 (2). Each of these factors has been significantly correlated with each other. Furthermore, these components also were compared with various domains of WHOQOL-BREF, and positive correlation was obtained for most of them. CONCLUSION: There is a positive association between ComSI and WHOQOL-BREF. This tool will help in identifying the satisfaction level of the aging subjects promptly and efficiently, which would further help in making strategies for interventions.

Fungal panniculitis in renal transplant recipients.

Panniculitis may result due to various etiologies. In post-transplant immunosuppressed patients infection is the foremost cause of panniculitis. We present 2 cases of fungal panniculitis in renal transplant recipients. The first patient presented with non-tender firm erythematous plaques on the left thigh. Biopsy showed panniculitis with cryptococci. Subsequent investigations revealed the presence of cryptococcal antigens in the blood, urine, and bronchoalveolar lavage fluid. There was no evidence of cryptococcal meningitis. The second patient complained of subcutaneous nodules on the trunk and right thigh. Biopsy of one of the nodules showed panniculitis with histoplasma. This patient had been treated earlier (inadequately) for disseminated histoplasmosis. Both the cases responded well to conventional amphotericin B therapy. Their renal functions remained stable.

Generic tacrolimus (Pan Graf) in renal transplantation: an experience of 155 recipients in India.

BACKGROUND: The safety and efficacy of tacrolimus in transplantation are well established. However, tacrolimus (Pan Graf) has only been available in India for the last 2 years. We conducted this study to assess the safety and efficacy of tacrolimus in living related kidney transplantation. Herein we have reported our experience with tacrolimus as de novo therapy in a living related renal transplant program. MATERIALS AND METHODS: One hundred fifty-five consecutive recipients of living donor renal allografts were included in this study after consent and ethical clearance. Immunosuppression consisted of tacrolimus, mycophenolate mofetil or azathioprine, and steroids. The dose of tacrolimus was adjusted according to levels done on a regular basis. All patients were followed for periods ranging from 3 to 33 months. All episodes of graft dysfunction were evaluated by a graft biopsy. We evaluated the effects of this regimen on the incidence of graft rejection, graft survival, patient survival, and new onset diabetes mellitus. Six patients were diabetic prior to transplantation and 9 patients were hepatitis C virus (HCV) positive. RESULTS: There were 137 male and 18 female patients. The incidence of acute rejection was 3.87%; 17.93% developed new onset diabetes mellitus; and 77.7% of HCV-positive patients and 14.07% of HCV-negative patients developed posttransplantation diabetes mellitus. The patient survival at the current follow-up was 94.19%. CONCLUSION: This generic form of tacrolimus is a safe, effective immunosuppressant in living related renal transplantation.

A prospective analysis of testicular androgenic function in recipients of a renal allograft.

Eighteen adult males with end stage renal disease (ESRD) were studied to determine the serum levels of gonadotropins (LH and FSH), prolactin (PRL) and testosterone. All of the patients were studied longitudinally while undergoing maintenance hemodialysis (HD) and six months after renal transplantation. Prior to transplantation, significantly high levels of gonadotropins and PRL were observed. During HD the serum testosterone levels tended to be subnormal in most of the uremic patients and low normal in some of the subjects. Renal transplantation led to a significant improvement (P < 0.05) in serum testosterone. Elevated gonadotropin and PRL levels observed in patients on HD returned to the normal range in most of the patients after successful renal transplantation.

Purpura fulminans in a complicated Falciparum malaria.

A 19-year-old male presented with fever, oliguria and purpuric lesions involving both hands. The patient was diagnosed as a case of purpura fulminans with disseminated intravascular coagulation due to complicated Falciparum malaria. The case is presented to sensitize the physicians to keep malaria as a differential in cases of fever with purpura fulminans.

Rare presentation of a common disease of tropics.

A 19 years male presented with fever, oliguria and purpuric lesions involving both hands. The patient was diagnosed as a case of purpura fulminans with disseminated intravascular coagulation due to complicated falciparum malaria. The case is presented to sensitize the physicians to keep malaria as a differential in cases of fever with purpura fulminans.

Public health strategies to stem the tide of chronic kidney disease in India.

It is estimated that 10-15% of the population has chronic kidney disease (CKD), resulting in significant health expenditure, which is largely met by out-of-pocket by the patient in India. However, the seriousness of this public health problem has remained largely under-recognized so far. Luckily the preventive measures are simple and not difficult to implement. Public health strategies are essential to control the burgeoning problem. Lifestyle modifications can reduce the incidence of obesity, hypertension and diabetes. These diseases account for a significant proportion of CKD cases. Active involvement of the primary care physicians is vital for early detection of CKD with retardation of its progress, since nephrologists do not see the patients in the early stages. The role of community health specialists is essential to organize health education programs and screening camps, form active patient support groups; and incorporate the prevention program in the various tiers of the health-care system. Availability of optimal nephrology services in peripheral hospitals can rehabilitate most cases of end-stage renal disease, and also prevent the illegal organ trade, which keeps rearing its ugly head at regular intervals in India.

Pattern of prescribing practices in the Madhya Pradesh, India.

OBJECTIVES: To find out the current status of the 'prescribing practices' in the Primary Health Care facilities of Madhya Pradesh. MATERIAL AND METHODS: The cross-sectional survey was conducted in 26 Primary Health Care facilities of the Madhya Pradesh. Consecutive random sampling method was applied for collection of prescriptions from the health facilities. OBSERVATION: Overall the average number of drugs prescribed per prescription was 2.8; most commonly prescribed drugs were NSAIDs, antibiotics, multivitamins and antihistaminics. Drugs prescribed by generic name were 48.5% (1409/2906), prescription with antibiotics and injections were 60.9% (641/1052) and 13.6% (143/1052) respectively. Drugs prescribed from Essential Drug List were 66.9% (1944/2906). CONCLUSION: The prescribing practices of the Madhya Pradesh is more of an irrational types like polypharmacy, overuse of antibiotics and injection, less number in generic names and prescribed from Essential Drug List. There is an urgent need for some interventions to improve the situation.

Prevalence of Psychiatric Illness among Residents of Old Age Homes in Northern India.

CONTEXT: There are many factors which compelled older adults to live in old age homes (OAHs) and vulnerable to psychological problems. Studies reported high prevalence of mental health problems (20%-60%) among elderlies of OAHs. Therefore, the study was conducted to explore prevalence of psychiatric illness (PI) among residents of OAHs of Northern India. SETTINGS AND DESIGN: The present study was conducted in OAHs of Districts Bareilly, Lucknow, Varanasi, Dehradun, and Haridwar, using cross-sectional descriptive study method. Sample Size were 306 (male - 98 [32.5%] and female n = 208 [68%]) residing in OAHs selected by means of purposive sampling. SUBJECTS AND METHODS: Inclusion criteria: (a) older adults aged 60 years and above residing in OAHs and able to communicate. (b) Staying in OAHs for 6 months or more. (c) Able to understand comprehends and reply to questions and (d) Giving written informed consent. Exclusion criteria: (a) Residents who declined/not interested to participate in the study. (b) Residents having any sensory impairment/physical health problem which can impede the interview. Research tools were (i) a semi-structured pro forma, (ii) Hindi Mental Status Examination, (iii) Survey psychiatric assessment schedule, and (iv) Schedules for clinical assessment in neuropsychiatry-based clinical interview for diagnosis of PIs according to International Classification of Disease 10. STATISTICAL ANALYSIS USED: The quantitative data obtained was analyzed by means of frequency tables. RESULTS: The results show overall prevalence of PI is 43% among residents of OAHs. The prevalence of PI was found to be higher among females compared to males. Depression was the most common among the residents of OAHs. CONCLUSIONS: There is an urgent need of trained professionals to provide professional help for highly prevalent psychiatric disorders among residents of OAHs.

Hepatitis C Virus-associated Membranoproliferative Glomerulonephritis Treated with Directly Acting Antiviral Therapy.

Hepatitis C virus (HCV) infection has been shown to affect kidneys with various histopathological pattern on the kidney biopsy. These commonly include a membranoproliferative glomerulonephritis (MPGN) pattern with mixed cryoglobulinemia (CG), thrombotic microangiopathy, membranous nephropathy, and vasculitis affecting medium and small vessels of the kidneys causing polyarteritis nodosa. It has been rarely associated with MPGN without detectable CG. We present one such patient who presented to us with HCV-associated MPGN without detectable CG, who recovered completely with directly acting antiviral therapy without any immunosuppression.

Prospective evaluation of psychological burden in patients with oral cancer.

The high morbidity and mortality that is associated with oral cancer places a huge psychological burden on patients. The purpose of this prospective study was to evaluate levels of depression, anxiety, and stress, at three time points using DASS-21 (Depression, Anxiety and Stress Scale-21). We also compared DASS-21 with HADS (Hospital Anxiety and Depression Scale). A total of 111 patients were enrolled and 75 of them completed the questionnaires at diagnosis, one month after treatment, and three months after discharge. Scores were high for stress at diagnosis, and for depression at the other time points, but were low for anxiety at all three. The results of Friedman's ANOVA showed that mean ranks for depression and stress were significant (p<0.05). Scores for depression and stress rose significantly between diagnosis and three months after operation, but those for anxiety (which had increased between diagnosis and operation p>0.05), were stable three months postoperatively. The DASS-21 was a useful method of evaluating stress. Correlation of the results from the two questionnaires showed a strongly positive association. We therefore recommend psychological intervention to improve overall outcome.

Tacrolimus (Pan Graf) in live related renal transplantation: an initial experience of 101 recipients in India.

BACKGROUND: Success of modern transplantation is in large part due to the successful development of effective immunosuppressive agents. The safety and efficacy of tacrolimus in transplantation is well established. However, tacrolimus (Pan Graf, Panacea Biotec Ltd, India) has only been available in India for the last 2 years. This study was conducted to assess the safety and efficacy of tacrolimus in live related kidney transplantation. We report an initial experience of tacrolimus as de novo therapy in a live related renal transplantation program. MATERIALS AND METHODS: One hundred one consecutive recipients of a live renal allograft were commenced on triple immunosuppression consisting of tacrolimus, mycophenolate mofetil or azathioprine, and steroids. The dose of tacrolimus was adjusted to keep trough levels at 10-12 ng/mL in the first 3 months, 8-10 ng/mL in the next 3 months, and 5-8 ng/mL thereafter. All patients were followed up for a period ranging from 4 weeks to 24 months. The effect of this regimen on the incidence of graft rejection, graft survival, patient survival, and new-onset diabetes mellitus was evaluated. Any evidence of graft dysfunction was evaluated using a graft biopsy. RESULTS: There were 89 male and 12 female patients with mean age of 32.08 years. The incidence of acute rejection was 3.96%; 21.05% developed new-onset diabetes mellitus. Six patients were diabetic prior to transplantation and 9 patients were hepatitis C virus (HCV)-positive; 77.7% of HCV-positive patients and 15.1% of HCV-negative patients developed posttransplantation diabetes mellitus. The patient survival rate at the current follow-up was 92.07%. No graft was lost due to rejection. CONCLUSION: Tacrolimus is a safe and effective immunosuppressant in live related renal transplantation.

Effect of bisphosphonates on bone mineral density after renal transplantation as assessed by bone mineral densitometry.

INTRODUCTION: Steroid-induced osteoporosis is a major problem after organ transplantation. There is considerable evidence that bisphosphonates are effective in decreasing osteoporosis. AIM: This prospective study was carried out to see the effects of bisphosphonates on bone mineral density (BMD) after successful renal transplantation. MATERIAL AND METHODS: Fifty consecutive patients of successful renal transplantation were randomized into two groups. Group A (n = 27) received 35 mg/wk of Alendronate for 6 months after transplantation. Group B (n = 23) did not receive Alendronate and served as a control. Both groups underwent a pretransplant baseline dual-energy X-ray absorptiometry (DEXA) scan of their hips and lumber spines. Both groups received oral calcium and vitamin D supplement. Both groups were matched for the regimen and dose of immunosuppressive drugs. BMD was measured at 3 months and 6 months after transplantation. RESULTS: Both groups showed a decline in BMD in early months posttransplantation. However, the 6-month DEXA scans showed a significant rise in BMD in group A as compared to group B. CONCLUSION: Bisphosphonates appear to have a beneficial effect on steroid-induced bone loss.

Chronic renal insufficiency among Asian Indians with type 2 diabetes: I. Role of RAAS gene polymorphisms.

BACKGROUND: Renal failure in diabetes is mediated by multiple pathways. Experimental and clinical evidences suggest that renin-angiotensin-aldosterone system (RAAS) has a crucial role in diabetic kidney disease. A relationship between the RAAS genotypes and chronic renal insufficiency (CRI) among type 2 diabetes subjects has therefore been speculated. We investigated the contribution of selected RAAS gene polymorphisms to CRI among type 2 diabetic Asian Indian subjects. METHODS: Twelve single nucleotide polymorphisms (SNPs) from six genes namely-renin (REN), angiotensinogen (ATG), angiotensin converting enzyme I (ACE), angiotensin II type 1 receptor (AT1) and aldosterone synthase (CYP11B2) gene from the RAAS pathway and one from chymase pathway were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method and tested for their association with diabetic CRI using a case-control approach. Successive cases presenting to study centres with type 2 diabetes of > or =2 years duration and moderate CRI diagnosed by serum creatinine > or =3 mg/dl after exclusion of non-diabetic causes of CRI (n = 196) were compared with diabetes subjects with no evidence of renal disease (n = 225). Logistic regression analysis was carried out to correlate various clinical parameters with genotypes, and to study pair wise interactions between SNPs of different genes. RESULTS: Of the 12 SNPs genotyped, Glu53Stop in AGT and A>T (-777) in AT1 genes, were monomorphic and not included for further analysis. We observed a highly significant association of Met235Thr SNP in angiotensinogen gene with CRI (O.R. 2.68, 95%CI: 2.01-3.57 for Thr allele, O.R. 2.94, 95%CI: 1.88-4.59 for Thr/Thr genotype and O.R. 2.68, 95%CI: 1.97-3.64 for ACC haplotype). A significant allelic and genotypic association of T>C (-344) SNP in aldosterone synthase gene (O.R. 1.57, 95%CI: 1.16-2.14 and O.R. 1.81, 95%CI: 1.21-2.71 respectively), and genotypic association of GA genotype of G>A (-1903) in chymase gene (O.R. 2.06, 95%CI: 1.34-3.17) were also observed. CONCLUSION: SNPs Met235Thr in angiotensinogen, T>C (-344) in aldosterone synthase, and G>A (-1903) in chymase genes are significantly associated with diabetic chronic renal insufficiency in Indian patients and warrant replication in larger sample sets. Use of such markers for prediction of susceptibility to diabetes specific renal disease in the ethnically Indian population appears promising.
