Clinical profile of tuberculosis in patients with chronic kidney disease: A report from an endemic Country
The objective is to study the clinical profile of tuberculosis (TB) in chronic kidney disease (CKD). This is retrospective study of CKD patients who were diagnosed to have TB over a period of seven years at a tertiary care hospital. TB was diagnosed in 115 patients with an incidence of 4200/100,000. Mean age of the patients was 46.9 ± 16 years. Sixty-two patients (53.9%) were male. Causes of CKD were diabetic nephropathy and hypertension in 11.3% each, chronic glomerulonephritis in 31.3%, chronic tubulointerstitial nephritis in 39.1%, autosomal dominant polycystic kidney disease, and post-renal transplant CKD in 3.5% each. About 68.7% of patients with TB had advanced CKD stage of 4–5D, whereas 31.3% of patients had early CKD stage 1–3. Twenty percent of patients were on dialysis. Three-fourths of the patients had extrapulmonary TB. Pleuropulmonary (41.8%), kidney and urinary tract (20%), and abdomen and lymph node (13% each) were the most common sites for TB. The main clinical presentation of TB was: fever/pyrexia of unknown origin in 24.3%, constitutional symptoms of anorexia, fever, night sweats, and weight loss in 27.8%, abnormal chest radiograph in 31.2%, ascites/peritonitis in 13.9%, pleural effusion in 25.2%, lymphadenopathy in 20%, and sterile pyuria/hematuria/chronic pyelonephritis in 13%. Microbiological and/or histopathological diagnoses were made in 45.2% and in the other 54.8%, diagnosis of TB was made on clinical grounds. Adverse effects of anti-TB drugs were seen in 9.6% of patients. Ninety-three percent completed the treatment and survived. Eight patients (7%), all in CKD stage 5D, died. The incidence of TB was high among CKD stages 4 and 5 and in those receiving dialysis. Extrapulmonary disease such as pleuropulmonary, renal, peritoneal, and lymph node were the common forms of TB
Dusky Warbler Phylloscopus fuscatus (Aves: Passeriformes: Sylviidae) in Sanjay Gandhi National Park, Maharashtra - a rare record for peninsular India
Dusky Warbler (Phylloscopus fuscatus) winters in certain Asian and European countries. It is commonly seen in the eastern parts of India but sporadically distributed in peninsular India. It was observed on few occasions at the site visited by authors. This report is for one of its rare sightings, in the peninsular region of India in Sanjay Gandhi National Park. </div
Autosomal dominant polycystic kidney disease: Study of clinical characteristics in an Indian population
Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary form of kidney disease. Clinical data on this multisystem disorder are scarce from developing countries. We conducted a prospective observational study of the clinical profile of ADPKD patients at a single center over a period of six years. A total of 208 patients were studied. Majority were male (60.6%) and the mean age was 45.8 ± 14.5 years. About 61.5% had early stage (Stages 1-3) of chronic kidney disease (CKD) and 38.5% had advanced CKD (Stages 4 and 5). Clinical features observed included pain abdomen (46.2%), nocturia (65.9%), hematuria (21.6%), nephrolithiasis (38.9%), urinary tract infection (UTI) (38.9%), hypertension (69.5%), and raised serum creatinine (54.3%). The prevalence of nocturia, hypertension, and renal dysfunction showed a significant increase with age (P = 0.001). Extrarenal manifestations were polycystic liver disease in 77 patients (37%), cysts in pancreas in two (1%), and stroke in three (1.5%) (hemorrhage in 2 and infarct in 1). There was significantly higher prevalence of hypertension (P = 0.027) and nephrolithiasis (P = 0.044) in males compared to females. Ninety-two patients (44.2%) had a positive family history for ADPKD. Fifteen (7.2%) had kidney failure at the diagnosis of ADPKD, were hospitalized, and underwent emergency dialysis. A total of 20 patients (9.6%) developed end-stage kidney disease during the study period. The age at diagnosis was higher, and there was a high prevalence of hypertension, nocturia, abdominal pain, nephrolithiasis, UTI, and renal dysfunction in Indian ADPKD patients
Prevalence and severity of disordered mineral metabolism in patients with chronic kidney disease: A study from a tertiary care hospital in India
Background: Disordered mineral metabolism is common complications of chronic kidney disease (CKD). However, there are limited data on the pattern of these disturbances in Indian CKD population. Materials and Methods: This was a prospective observational study of CKD-mineral and bone disorder (CKD-MBD) over a period of 3 years. The biochemical markers of CKD-MBD, namely, calcium, phosphorus, alkaline phosphatase, intact parathyroid hormone (iPTH), and 25-hydoxyvitamin Vitamin D3 (25OHD), were measured in newly diagnosed CKD Stage 3–5 and prevalent CKD Stage 5D adult patients. Results: A total of 462 patients of CKD Stage 3–5D were studied. The frequency of various biochemical abnormalities was hypocalcemia (23.8%), hypercalcemia (5.4%), hypophosphatemia (2.8%), hyperphosphatemia (55.4%), raised alkaline phosphatase (56.9%), secondary hyperparathyroidism (82.7%), and hypoparathyroidism (1.5%). 25OHD was done in 335 (72.5%) patients and 90.4% were found to have Vitamin D deficiency. About 70.6% of the patients had iPTH levels were above kidney disease outcomes quality initiative (KDOQI) target range. Nondiabetic CKD as compared to diabetic CKD had a higher alkaline phosphatase (P = 0.016), a higher iPTH (P = 0.001) a higher proportion of patients with iPTH above KDOQI target range (P = 0.09), and an elevated alkaline phosphatase (P = 0.004). The 25OHD levels were suggestive of severe Vitamin D deficiency in 33.7%, Vitamin D deficiency in 45.4%, and Vitamin D insufficiency in 11.3% patients. There was a significant positive correlation between iPTH with alkaline phosphatase (r = 0.572, P = 0.001), creatinine (r = 0.424, P = 0.001), and phosphorus (r = 0.241, P = 0.001) and a significant negative correlation with hemoglobin (r = −0.325, 0.001), age (r = −0.169, P = 0.002), and 25OHD (r = −0.126, P = 0.021). On multivariate logistic regression analysis, an elevated alkaline phosphatase was a significant predictor of hyperparathyroidism (odds ratio 9.7, 95% confidence interval 4.9–19.2, P = 0.001). Conclusions: There was a high prevalence of CKD-MBD in Indian CKD patients. CKD-MBD is more common and more severe and has an early onset as compared to the western populations
Extended-spectrum beta-lactamase-producing klebsiella pneumoniae causing peritonitis in a patient on continuous ambulatory peritoneal dialysis
Securitization and mortgage default
The academic literature, the popular press, and policymakers have all debated securitization's contribution to the poor performance of mortgages originated in the run-up to the recent crisis. Theoretical arguments have been advanced on both sides, but the lack of suitable data has made it difficult to assess them empirically. The author examines this issue by using a loan-level data set from LPS Analytics, covering approximately two-thirds of the mortgages originated in 2005 and 2006, and including both securitized and nonsecuritized loans. ; The author finds evidence that privately securitized loans do indeed perform worse than observably similar, nonsecuritized loans. Moreover, this effect is strongest in prime mortgage markets, which have not been studied in the previous literature. For example, a typical prime loan becomes delinquent at a 20 percent higher rate if it is privately securitized, ceteris paribus. This is consistent with the existence of adverse selection; that is, that lenders used information not available to investors to securitize loans that were riskier than they otherwise appeared. By contrast, for subprime mortgages, the impact of private securitization is concentrated in low or no-documentation loans; this latter result is consistent with previous work such as Keys et al. (2009).Mortgage-backed securities ; Default (Finance)
Sodium stibogluconate-associated acute interstitial nephritis in a patient treated for visceral leishmaniasis
The spectrum of side-effects of sodium stibogluconate is well described. Patients treated with sodium stibogluconate can develop varied manifestations of renal toxicity, ranging from renal cell casts, proteinuria, renal tubular acidosis and acute tubular necrosis, resulting in acute kidney injury (AKI). We describe a 32-year-old male patient who was treated for visceral leishmaniasis with sodium stibogluconate. The patient was readmitted two weeks after completion of the treatment for evaluation of AKI. Kidney biopsy revealed marked acute interstitial nephritis. The renal dysfunction reversed totally after a course of corticosteroids. Antimonials should be recognized as a new class of agents as a possible cause of drug-induced acute interstitial nephritis
Role of Risk Stratification and Genetics in Sudden Cardiac Death
Sudden cardiac death (SCD) is a major public health issue due to its increasing incidence in the general population and the difficulty in identifying high-risk individuals. Nearly 300,000-350,000 patients in the United States and 4- to 5 million patients in the world die from SCD. Coronary artery disease and advanced heart failure are the main etiology for SCD. Ischemia of any cause precipitates lethal arrhythmias, and ventricular tachycardia and ventricular fibrillation are the most common lethal arrhythmias precipitating SCD. Pulse-less electrical activity, brady-arrhythmia and electromechanical dissociation also result in SCD. Most sudden cardiac deaths occur out-of-the-hospital setting, so it is difficult to estimate the public burden, which results in overestimating the incidence of SCD. The insufficiency and limited predictive value of various indicators and criteria for SCD result in the increasing incidences. As a result, there is a need to develop better risk stratification criteria and find modifiable variables to decrease the incidence. Primary and secondary prevention and treatment of SCD need further research. This critical review is focused on the etiology, risk factors, prognostic factors and importance of risk stratification of SCD.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Epidemiology and outcome of acute kidney injury from a tertiary care hospital in India
We aimed to study the epidemiology and outcome of acute kidney injury (AKI). This is a prospective study of adults aged 18 years or above diagnosed with AKI over a period of 16 months at a tertiary care hospital. Three hundred and nine patients had AKI. The observed incidence of AKI was eight per 1000 admissions. About 92.2% had community-acquired AKI (CA-AKI), and in 7.8% it was hospital-acquired AKI (HA-AKI). Etiological factors for AKI were medical in 87.4% of the cases, surgical in 9.4%, and obstetric 3.2%. Sepsis was the most common (53.1%) etiology of AKI among the medical cases. Among sepsis, scrub typhus, urosepsis, and pneumonia were the most common causes of AKI. Hypovolemia (9.4%), biological toxins (8.4%), nephrotoxic drugs and chemicals (7.4%), cardiac causes (7.4%), and acute glomerulonephritis (1.9%) were other medical causes of AKI. Nearly 38.2% had multiorgan failure, 20.1% required vasopressors, 6.1 % required Intensive Care Unit support, and 23.3% required dialysis. Mortality was 8.7%. Anemia, use of vasopressor drugs, and need for intensive care support were independent predictive factors for mortality. AKI is common in hospitalized adults in India and leads to significant in-hospital mortality. AKI is largely a CA-AKI and the lesser percentage is due to HA-AKI. Many causes are potentially preventable. Early fluid resuscitation, effective anti-infective treatment, appropriate antidotes, and timely referral of established AKI patients to centers with dialysis facilities can improve AKI outcomes
