Carbapenemase-Producing Klebsiella pneumoniae Infections in Diabetic and Nondiabetic Hospitalized Patients.

BACKGROUND: Carbapenem-resistant Klebsiella pneumoniae (CRKP) infection has recently attracted widespread attention due to its limited treatment options and significant morbidity and mortality rates. This study aimed to examine the relationship between risk factors and antimicrobial resistance in individuals with and without diabetes for the development of carbapenemase-producing K. pneumoniae infections. METHODS: Between May 2019 and January 2021, a prospective study involving patients with and without diabetes who were infected with K. pneumonia, was carried out in a tertiary care hospital. Six hundred K. pneumoniae isolates were collected from various clinical samples, such as pus/wound samples, urine, respiratory samples, blood, and body fluids. An antimicrobial susceptibility test in K. pneumoniae was performed and compared between diabetics and nondiabetics. Univariate and multivariate logistic regression were used to identify independent risk factors for K. pneumoniae infections in the diabetic group and nondiabetic group separately. Multiplex PCR was used to detect genes that produce carbapenemase. RESULTS: A total of 600 patients were infected with K. pneumoniae, with 300 (50%) being diabetic and 300 (50%) being nondiabetic. We found that diabetics had higher antimicrobial resistance to numerous routinely used drugs for infection than the nondiabetic group. In the multivariate analysis of the variables, it was found that immunosuppressive therapy, prior antibiotic use, mechanical ventilation, and urinary catheter use were all significant risk factors influencing the development of K. pneumoniae infections in diabetic patients. Diabetics had a higher prevalence of carbapenemase-producing K. pneumoniae than nondiabetics. Outcome measures in K. pneumoniae patients revealed that the diabetic group had considerably higher infection-related mortality. CONCLUSION: We found that CRKP infection was associated with higher resistance to antibiotics in the diabetic group. Furthermore, the diabetic group had a higher prevalence of carbapenemase-producing K. pneumoniae than the nondiabetic group. Crucially, in order to lower mortality without worsening antibiotic resistance and metabolic damage, more focus has to be placed on sensible and efficient antibiotic and supportive care therapies.

Clinical and Molecular Profile of Carbapenem Resistant Klebsiella pneumoniae Infections in a Tertiary Care Hospital -Mangalore.

Purpose: Carbapenemase producing Klebsiella pneumoniae infection has increased in recent years, leading to limitations in treatment options. The present study was undertaken to detect the Carbapenemase-producing genes in K. pneumoniae, the risk factors for acquiring them, and their impact on clinical outcomes. Patients and Methods: This prospective study included 786 clinically significant K. pneumoniae isolates. Antimicrobial susceptibility testing was done by conventional method, carbapenem-resistant isolates were screened by carba NP test, and positive isolates were further evaluated by multiplex PCR method. The patient's clinical and demographic details, co morbidity, and mortality were collected. Multivariate analysis was performed to check risk factors for acquiring CRKP infection. Results: The results of our study showed high prevalence of CRKP (68%). The variables subjected to the multivariate analysis found that diabetes, hypertension, cardiovascular disease, COPD, use of immunosuppressants, previous hospitalization history, previous surgery, and parenteral nutrition are found to be significantly associated with carbapenem resistant K. pneumoniae infection. Clinical outcomes revealed that patients in the CRKP group had higher risk of mortality and were discharged against medical advice, and they also had higher rate of septic shock. Most of the isolates carried blaNDM-1 and blaOXA-48 carbapenemase genes. Additionally, the co-existence of blaNDM-1 and blaOXA-48 was found in our isolates. Conclusion: The prevalence of CRKP was alarmingly high in our hospital with the limited choice of antibiotics. This was associated with high mortality and morbidity with the increase in health care burden. While this information is important to treat critically ill patients with higher antibiotics, strict infection control practices need to be in place to prevent the spread of these infections in the hospital. Clinicians need to be aware of this infection to use appropriate antibiotics to save the lives of critically ill patients with the infection.

Evaluation of Madras Diabetes Research Foundation-Indian Diabetes Risk Score in detecting undiagnosed diabetes in the Indian population: Results from the Indian Council of Medical Research-INdia DIABetes population-based study (INDIAB-15).

Background & objectives: Screening of individuals for early detection and identification of undiagnosed diabetes can help in reducing the burden of diabetic complications. This study aimed to evaluate the performance of Madras Diabetes Research Foundation (MDRF)-Indian Diabetes Risk Score (IDRS) to screen for undiagnosed type 2 diabetes in a large representative population in India. Methods: Data were acquired from the Indian Council of Medical Research-INdia DIABetes (ICMR-INDIAB) study, a large national survey that included both urban and rural populations from 30 states/union territories in India. Stratified multistage design was followed to obtain a sample of 113,043 individuals (94.2% response rate). MDRF-IDRS used four simple parameters, viz. age, waist circumference, family history of diabetes and physical activity to detect undiagnosed diabetes. Receiver operating characteristic (ROC) with area under the curve (AUC) was used to assess the performance of MDRF-IDRS. Results: We identified that 32.4, 52.7 and 14.9 per cent of the general population were under high-, moderate- and low-risk category of diabetes. Among the newly diagnosed individuals with diabetes [diagnosed by oral glucose tolerance test (OGTT)], 60.2, 35.9 and 3.9 per cent were identified under high-, moderate- and low-risk categories of IDRS. The ROC-AUC for the identification of diabetes was 0.697 (95% confidence interval: 0.684-0.709) for urban population and 0.694 (0.684-0.704) for rural, as well as 0.693 (0.682-0.705) for males and 0.707 (0.697-0.718) for females. MDRF-IDRS performed well when the population were sub-categorized by state or by regions. Interpretation & conclusions: Performance of MDRF-IDRS is evaluated across the nation and is found to be suitable for easy and effective screening of diabetes in Asian Indians.

Parkinsonism: An emerging post COVID sequelae.

Parkinsonism has a complex and multifactorial aetiology and the role of post viral infection parkinsonism has been documented. The recent pandemic has made it clear that COVID-19 causes respiratory disease and affects multiple organs, which includes the central nervous system. Here we report three cases of post COVID parkinsonism occurring in older adults, age 60 years and above, and their response to levodopa-carbidopa.

Xanthogranulomatous pyelonephritis due to Aspergillus in a non-diabetic older patient.

Xanthogranulomatous pyelonephritis is a rare condition characterised by destructive granulomatous inflammation of renal parenchyma. Primary renal Aspergillosis has been reported in patients with immunocompromised states such as diabetes, retroviral disease, organ transplant recipients, etc. We present a unique case of an older adult in his early 60s, presenting with fever and left flank pain with renal angle tenderness, diagnosed with primary renal aspergillosis with xanthogranulomatous pyelonephritis. These symptoms resolved with a long duration of antifungal (itraconazole) therapy and nephrectomy. The unique features are the development of fungal pyelonephritis in the absence of any immunocompromising conditions and the development of xanthogranulomatous changes with no risk factors.

Depression among older adults: a systematic review of South Asian countries.

The world's population has been evolving rapidly; every country in the world is facing this drastic progression in the number and the percentage of the elderly in their net population. As the chronological age advances, physiological and psychosocial decline will be evident among all older adults. The potentially relevant literature was identified using appropriate search terms in electronic databases such as PubMed MEDLINE, Scopus, ProQuest, Web of Science, CINAHL, IndMed, and Google Scholar. Articles published from 2006 to 2019, reported the prevalence and the risk factors for depression among older adults living in the community, old age homes, or hospitals of the South Asian countries. Articles were published in the languages other than English and those reporting the categorised or mean depressive scores were excluded from the review. After quality check for all the retrieved articles from different databases, 120 articles were included for the meta-analysis. The data were extracted based on a validated data extraction form, and the reviewer contacted the authors for clarification of the missing data whenever required. The estimates were pooled using the random effect model for meta-analyses. Sub-group and sensitivity analyses were also performed. The overall pooled estimate (random effect models) of the prevalence of depression among the elderly was 42.0% (95% CI: 0.38-0.46), Chi-squared P-value <0.001, and I2 99.14%. The pooled estimate of the prevalence was higher in the community settings than the old age homes (44.0%; 95% CI: 39.0-49.0 vs. 42.0%; 95% CI: 34.0-49.0). Depression is a common problem among the elderly population and the pooled estimate of depression would give directions to the healthcare providers, policymakers, and future researchers to plan some measures (either pharmacological or non-pharmacological interventions) to effectively tackle the burden of geriatric depression in the future.

Effect of licorice on patients with HSD11B1 gene polymorphisms- a pilot study.

The positive association of HSD11B1 gene polymorphism with type 2 diabetes (T2D) and prediabetic conditions has been revealed. In the current study, we assessed the effectiveness of licorice on the clinical profile of the patients with HSD11B1 gene polymorphism. Licorice (Glycyrrhiza Glabra) is a competitive inhibitor of 11 beta-hydroxysteroid dehydrogenase 1 (11ß-HSD1) enzyme and has been traditionally reported as an anti-ulcer, anti-pyretic, anti-thirst, anti-inflammatory, hypoglycemic and hypolipidemic agent. The aim of the study was to assess the effectiveness of licorice on the clinical profile of participants with HSD11B1 gene polymorphism. The study was performed using diabetic patients with HSD11B1 gene polymorphism. Biochemical and anthropometric parameters were measured using standard diagnostic tools. Fourteen patients were divided into two groups by simple randomization, Licorice group (treated with 750 mg licorice/day for three weeks), and placebo group (treated with 750 mg placebo/day for three weeks). Investigations were repeated at the end of three weeks. Licorice showed a significant reduction in serum insulin levels (p = 0.03). There was no significant change in any other clinical parameters either by licorice or placebo. Conclusively, licorice moderately improves serum insulin levels in patients with HSD11B1 gene polymorphism. From our pilot study, the safety of licorice is confirmed at a dose of 750 mg/day. However, the study can be repeated at a higher dose to show its effectiveness and safety.

CpG-SNP site methylation regulates allele-specific expression of MTHFD1 gene in type 2 diabetes.

The interaction of genetic and epigenetic mechanisms is one of the underlying causes of phenotypic variability in complex diseases such as type 2 diabetes (T2D). To explore the influence of genetic and epigenetic changes in T2D, we examined the effect of methylation of CpG-SNP sites on allele-specific expression (ASE) in one-carbon metabolism pathway genes in T2D. Case-control study was conducted on 860 individuals (430 T2D and 430 controls). CpG-SNPs shortlisted through in silico analysis were genotyped using tetra ARMS PCR and validated using Sanger DNA sequencing. Global DNA methylation was carried out using RP-HPLC. Promoter DNA methylation and CpG site-specific methylation were carried out using bisulfite sequencing. mRNA expression and ASE were examined by SYBR green and TaqMan assay, respectively. Four exonic CpG-SNPs of MTHFD1, MTRR, and GGH genes were identified in folate pathway genes. Among these, MTHFD1 rs2236225 showed significant association with T2D independent of obesity, displayed ASE, and correlated with CpG-SNP site-specific methylation when compared with controls. Our results demonstrate that SNP rs2236225 in the CpG site of MTHFD1, which regulates allele-specific gene expression in PBMCs is methylation dependent and may perturb one-carbon metabolism pathway in T2D subjects.

Effects of Yoga Versus Sham Yoga on Oxidative Stress, Glycemic Status, and Anthropometry in Type 2 Diabetes Mellitus: A Single-Blinded Randomized Pilot Study.

Studies have shown a beneficial role of yoga in tre a t i n g type 2 diabetes mellitus. The present study proceeds in the field by providing an active control. We aimed to evaluate the effect of 3 months of yoga on oxidative stress, glycemic status, and anthropometry in type 2 diabetes mellitus. Forty participants were randomized to receive either yoga (n = 20) or sham yoga (n = 20) as a control. Yoga included postures and breathing exercises, and nonaerobic stretching exercise comprised the control. Significant within-group differences in malondialdehyde, vitamin C, superoxide dismutase, fasting blood glucose, glycosylated hemoglobin, body mass index, waist circumference, and blood pressure were evident in both groups. Yoga participants had significantly greater improvement in reduced glutathione compared to controls. No significant differences between groups were observed in any other outcome variables. Yoga and sham yoga had identical effects on oxidative stress, glycemic status, and anthropometry in type 2 diabetes mellitus. Levels of reduced glutathione improved only in the yoga group. This research needs to be confirmed by larger and sufficiently powered studies.

A Prospective Study of the Clinical and Demographic Profile of Type 2 Diabetes Mellitus Patients Receiving Antidiabetic Drug Combinations.

BACKGROUND: The specific treatment recommendations for type 2 diabetes mellitus (T2DM) differ based on a particular guideline. The goal of pharmacotherapy is to achieve the target HbA1c and fasting and postprandial blood glucose levels to avoid disease complications. OBJECTIVE: To evaluate the profile of T2DM patients on different antidiabetic treatment regimens and the factors leading to dose escalation in these patients. METHODS: A prospective descriptive study was conducted at Kasturba Medical College Hospital, Mangalore, a tertiary care teaching hospital, over a period of one year. The study population comprised of patients with T2DM for ≥5 years. The demographic and clinical data were collected during the baseline and follow-up visits. RESULTS: Of the 119 patients studied, 59.7% were males; 32.8% were ≥65 years of age. A significant decrease in the fasting blood glucose (FBG) on follow-up was seen (p = 0.028) in patients on sulfonylurea and metformin combination. A significant decrease in the glycated haemoglobin (HbA1c) was seen in patients on sulfonylurea with metformin and pioglitazone (p = 0.011); sulfonylurea with metformin, pioglitazone, and sitagliptin (p = 0.026); and metformin with insulin (p = 0.001). Patients who received dose escalation had a longer duration of the disease (p = 0.042), higher FBG (p = 0.039) and HbA1c (p = 0.05). CONCLUSION: A combination of metformin with sulfonylurea was the preferred first-line treatment; insulin was added when HbA1c was >9. Patients who received dose escalation had a longer duration of the disease and higher FBG and HbA1c.

Comprehensive Review on Diabetes Associated Cardiovascular Complications - The Vitamin D Perspective.

Vitamin D, a steroid hormone is primarily known for its role in calcium and bone mineral homeostasis. Over the years, vitamin D has been implicated in various non-skeletal diseases. The extraskeletal phenomenon can be attributed to the presence of vitamin D receptors (VDRs) in almost all cells and identification of 1-α hydroxylase in extrarenal tissues. The vitamin D deficiency (VDD) pandemic was globally reported with increasing evidence and paralleled the prevalence of diabetes, obesity and cardiovascular diseases (CVDs). A dependent link was proposed between hypovitaminosis D glycemic status, insulin resistance and also the other major factors associated with type 2 diabetes leading to CVDs. Insulin resistance plays a central role in both type 2 diabetes and insulin resistance syndrome. These 2 disorders are associated with distinct etiologies including hypertension, atherogenic dyslipidemia, and significant vascular abnormalities that could lead to endothelial dysfunction. Evidence from randomised clinical trials and meta-analysis, however, yielded conflicting results. This review summarizes the role of vitamin D in the regulation of glucose homeostasis with an emphasis on insulin resistance, blood pressure, dyslipidaemia, endothelial dysfunction and related cardiovascular diseases and also underline the plausible mechanisms for all the documented effects.

Implication of critical pharmacokinetic gene variants on therapeutic response to metformin in Type 2 diabetes.

AIM: Metformin, an oral hypoglycemic drug is the first line of treatment for Type 2 diabetes individuals. We studied the effect of critical gene single nucleotide polymorphisms  on the glucose lowering effect of metformin. METHOD: We performed a prospective study on 221 newly diagnosed, treatment-naive Type 2 diabetes subjects. Individuals were started with metformin monotherapy and followed up for 12 weeks. RESULTS: Our association analysis revealed that SLC22A2 rs316019 and SLC47A2 rs12943590 were significantly associated with metformin drug response across co-dominant and dominant models, respectively. SLC22A2 rs316019 GG and SLC47A2 rs12943590 GA combined genotypes showed maximum average change in HbA1c level. CONCLUSION: The present study proposes a role of SLC22A2 rs316019 and SLC47A2 rs12943590 in the pharmacokinetic action of metformin.

Clinical and microbiological profile of diabetic foot ulcer patients in a tertiary care hospital.

AIM: To evaluate the clinical and microbiological profile of diabetic foot ulcer patients admitted to a tertiary care hospital. METHODOLOGY: This study recruited 120 diabetic foot ulcer patients of all grade. Their medical records were evaluated retrospectively. RESULTS: We found that median age of patient was 60(52, 67.75) years. 68.3% of patients were males. Median duration of diabetes mellitus was 15(10, 20) years. Mean HbA1C and fasting glucose was 10.3±2.3 and 167.6±52.42 respectively. Neuropathy (35%) and peripheral vascular disease (23.3%) was major micro vascular and macro vascular complication associated. Different locations of ulcers were toe (23.3%), sole (20%), dorsum (18.3%), shin (16.6%), heel (13.3%), and ankle (8.3%). Bacterial infection was seen in 81.66% patients out of which 23.3% had poly microbial infection. CONCLUSION: Diabetic foot ulcer patient had poor blood glucose control with elevated HbA1C and fasting blood glucose level. Neuropathy and peripheral vascular disease, hypertension were major complications. Staphylococcus aureus, Pseudomonas aeruginosa were common infecting bacteria.

Molecular characterisation of uropathogenic Escherichia coli isolates at a tertiary care hospital in South India.

Uropathogenic Escherichia coli (UPEC) express a multitude of virulence factors (VFs) to break the inertia of the mucosal barrier of the urinary tract. The aim of the present study was undertaken to characterised the UPEC strains and to correlate carriage of specific virulence markers with different phylogroups and also to correlate these findings with clinical outcome of patients. A total of 156 non-repeated, clinically significant UPEC isolates were studied. Virulent genes were determined by two set of multiplex polymerase chain reaction (PCR). Phylogenetic analysis was performed by triplex PCR methods. Antibiograms and patient's clinical outcomes were collected in a structured pro forma. Of the 156 patients infected by UPEC strains with significant bacterial counts the most common predisposing factors were diabetes (45.5%) followed by carcinoma (7%). On analysis of the VF genes of the isolates, a majority of strains (140; 90%) were possessing the fimH gene followed by iutA (98; 63%), papC (76; 49%), cnf1 (46; 29.5%), hlyA (45; 29%) and neuC (8; 5%), respectively. On phylogenetic analysis, 27 (17%) isolates were belong to phylogroup A, 16 (10%) strains to Group B1, 59 (38%) were from Group B2 and 54 (35%) were from Group D. High prevalence of antibiotic resistance was observed among the isolates. The incidence of papC, cnf1 and hlyA was significantly higher (P < 0.05) among the isolates from relapse patients. Our findings indicate that virulent as well as commensal strains are capable of causing urinary tract infection. Virulence genes as well as patients-related factors are equally responsible for the development of infections and also that virulence genes may help such isolates to persist even with appropriate chemotherapy and be responsible for recurrent infections.

Association of HSD11B1 gene polymorphisms with type 2 diabetes and metabolic syndrome in South Indian population.

BACKGROUND: 11beta-hydroxysteroid dehydrogenase Type 1 (11ß-HSD1) is an NADP or NADPH-dependent enzyme that generates cortisol from cortisone for a local glucocorticoid action. Functional polymorphisms within 11beta-hydroxysteroid dehydrogenase Type 1 (HSD11B1) gene have shown an association with various factors, including insulin resistance (IR) and hypertension. In our study, we have assessed the association of HSD11B1 (rs12086634 and rs846910) gene polymorphisms with type 2 diabetes (T2D) and metabolic syndrome (metS). METHODS: In the present study, 616 subjects were enrolled. DNA from T2D subjects (n=207), metS subjects (n=101), and their age and sex matched control subjects were analyzed. Genotyping of HSD11B1 rs12086634 and rs846910 single nucleotide polymorphisms was performed using tetra-primer amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR). An odds ratio and 95% confidence interval were calculated to determine the association of HSD11B1 gene polymorphisms with T2D and metS. RESULTS: The association analysis indicated that HSD11B1 rs12086634 TG contributed to an increased risk of both T2D (OR=1.91; 95% CI-1.33-2.76, P=0.0005) and metS (OR=2.37; 95% CI-1.39-4.05, P=0.0015), but HSD11B1 rs846910 AG contributed to an increased risk of T2D (OR=1.62; 95% CI-1.02-2.57, P=0.03) only. There was a statistically significant difference in systolic blood pressure between the control group with HSD11B1 rs12086634 TG genotype (128.96±13.19mmHg) and the control group with HSD11B1 rs12086634 TT genotype (123.27±10.84mmHg). CONCLUSIONS: The results of our study indicated that the HSD11B1 rs12086634 is associated with both T2D and metS, but HSD11B1 rs846910 is associated with only T2D in South Indian population.

Prevalence of diabetes and prediabetes in 15 states of India: results from the ICMR-INDIAB population-based cross-sectional study.

BACKGROUND: Previous studies have not adequately captured the heterogeneous nature of the diabetes epidemic in India. The aim of the ongoing national Indian Council of Medical Research-INdia DIABetes study is to estimate the national prevalence of diabetes and prediabetes in India by estimating the prevalence by state. METHODS: We used a stratified multistage design to obtain a community-based sample of 57 117 individuals aged 20 years or older. The sample population represented 14 of India's 28 states (eight from the mainland and six from the northeast of the country) and one union territory. States were sampled in a phased manner: phase I included Tamil Nadu, Chandigarh, Jharkhand, and Maharashtra, sampled between Nov 17, 2008, and April 16, 2010; phase II included Andhra Pradesh, Bihar, Gujarat, Karnataka, and Punjab, sampled between Sept 24, 2012, and July 26, 2013; and the northeastern phase included Assam, Mizoram, Arunachal Pradesh, Tripura, Manipur, and Meghalaya, with sampling done between Jan 5, 2012, and July 3, 2015. Capillary oral glucose tolerance tests were used to diagnose diabetes and prediabetes in accordance with WHO criteria. Our methods did not allow us to differentiate between type 1 and type 2 diabetes. The prevalence of diabetes in different states was assessed in relation to socioeconomic status (SES) of individuals and the per-capita gross domestic product (GDP) of each state. We used multiple logistic regression analysis to examine the association of various factors with the prevalence of diabetes and prediabetes. FINDINGS: The overall prevalence of diabetes in all 15 states of India was 7·3% (95% CI 7·0-7·5). The prevalence of diabetes varied from 4·3% in Bihar (95% CI 3·7-5·0) to 10·0% (8·7-11·2) in Punjab and was higher in urban areas (11·2%, 10·6-11·8) than in rural areas (5·2%, 4·9-5·4; p<0·0001) and higher in mainland states (8·3%, 7·9-8·7) than in the northeast (5·9%, 5·5-6·2; p<0·0001). Overall, 1862 (47·3%) of 3938 individuals identified as having diabetes had not been diagnosed previously. States with higher per-capita GDP seemed to have a higher prevalence of diabetes (eg, Chandigarh, which had the highest GDP of US$ 3433, had the highest prevalence of 13·6%, 12.8-15·2). In rural areas of all states, diabetes was more prevalent in individuals of higher SES. However, in urban areas of some of the more affluent states (Chandigarh, Maharashtra, and Tamil Nadu), diabetes prevalence was higher in people with lower SES. The overall prevalence of prediabetes in all 15 states was 10·3% (10·0-10·6). The prevalence of prediabetes varied from 6·0% (5·1-6·8) in Mizoram to 14·7% (13·6-15·9) in Tripura, and the prevalence of impaired fasting glucose was generally higher than the prevalence of impaired glucose tolerance. Age, male sex, obesity, hypertension, and family history of diabetes were independent risk factors for diabetes in both urban and rural areas. INTERPRETATION: There are large differences in diabetes prevalence between states in India. Our results show evidence of an epidemiological transition, with a higher prevalence of diabetes in low SES groups in the urban areas of the more economically developed states. The spread of diabetes to economically disadvantaged sections of society is a matter of great concern, warranting urgent preventive measures.

Development and validation of health related quality of life questionnaire (Indian scenario) in diabetic foot ulcer patients.

AIM: To develop and validate Health Related Quality of Life Questionnaire in Diabetic Foot Ulcer Patients (HRQLQDFU) for Indian scenario. MATERIALS AND METHODS: This study was conducted in two phases. First phase was Development of HRQLQDFU which included literature search and expert interview. Second phase was validation of HRQLQDFL which included face validation, content validation and construct validation. Face validation was done by ten diabetic foot ulcer patients, ten practicing nurses and ten care givers. They were asked to read and respond to questionnaire and report any difficulty in understanding the questions. Further they were asked to add any item to the questionnaire which according to them has a significant effect on quality of life. Content validation was done by six subject experts who judged the content relevance of questionnaire with score ranging from zero to four; zero being least relevant and four being most relevant. Content validity index was calculated for each question. Questions having content validity index≥0.8 were selected for the study. Reliability was tested by calculating Cronbach's alpha. RESULTS: In the development phase a questionnaire containing 37 questions with six domains was developed. None of patient had difficulty in understanding questions. After content validation a new questionnaire containing 20 questions was developed. Cronbach's alpha was 0.86 which shows good reliability. CONCLUSION: The new health related quality of life questionnaire on diabetic foot ulcer patients for an Indian scenario is validated and can be a reliably measure for quality of life in diabetic foot ulcer patients.

Is diabetes mellitus an important risk factor for the antibiotic resistance in extraintestinal pathogenic Escherichia coli?

Escherichia coli is a major cause of extraintestinal infections in all age group. However, the infection becomes more severe when patients have some underlying condition such as Diabetes Mellitus. The aim of the study was to determine whether diabetic mellitus may act as an important risk factor for the E. coli to express drug resistance property. This descriptive study was carried out in a multi-specialty tertiary care hospital. One hundred and twenty-seven E. coli isolates from diabetic patients, and one hundred seventy-three isolates from nondiabetic patients were studied. Possession drug resistance genes were determined by multiplex polymerase chain reaction (PCR). Phylogenetic analysis was performed by triplex PCR. Antibiotic sensitivity testing was performed by Kirby-Bauer disk diffusion method. Among the study isolates from Diabetic patients maximum numbers were from phylogroup B2 (42.5%) and D (33%) similarly in case of nondiabetic patients B2 (29%) and D (38%) were the most common phylogroup. Presence of drug resistance genes among the diabetic and nondiabetic patient's isolates were as followed extended-spectrum beta-lactamase (70% and 70.5%) AmpC (9.5% and 14.5%) and NDM-1 ( 7% and 4.5%) and by disk diffusion methods susceptibility pattern were meropenem (94% and 94%), imipenem (92% and 92%), amikacin (76% and 74%), and ampicillin/sulbactam (68% and 69%), respectively. The proportion of diabetic patients strains with the drug resistance characteristics were not significantly different from that seen in nondiabetic patients strains, which indicating that in a predisposed host additional or subtraction bacterial aids for drug resistance property are not a necessity.

Prevalence of Vitamin B12 and folic acid deficiency in HIV-positive patients and its association with neuropsychiatric symptoms and immunological response.

BACKGROUND: Deficiency of micronutrients is prevalent even before the development of symptoms of HIV disease and is associated with accelerated HIV disease progression. AIMS: This study evaluates the prevalence of folate and Vitamin B12 deficiency in HIV-positive patients with or without tuberculosis (TB) and its association with neuropsychiatric symptoms and immunological response. SETTINGS AND DESIGN: Cross-sectional, observational study in an outpatient setting. PATIENTS AND METHODS: Four groups of HIV-positive patients with TB (Group I), HIV-positive patients with neuropsychiatric symptoms (Group II), HIV-positive patients without neuropsychiatric symptoms or TB (Group III), and HIV-negative controls with neuropsychiatric symptoms (Group IV). Vitamin B12 and folate estimation was done using carbonyl metallo-immunoassay method. STATISTICAL ANALYSIS USED: ANOVA, Kruskal-Wallis and Mann-Whitney, Pearson's correlation. RESULTS: The prevalence of folic acid deficiency was 27.1% in the Group I, 31.9% in the Group II, 23.4% in the Group III, and 32% in the Group IV being higher in patients with neuropsychiatric symptoms in both HIV and non-HIV patients. The prevalence of Vitamin B12 deficiency was 18.8% in Group I, 9.1% in Group II, 4.8% in Group III, and 16.7% in Group IV. The patients with folate deficiency had more severe depression and anxiety. CONCLUSION: Nearly, 30% of the HIV patients had a folic acid deficiency, and about 10% of the HIV patients had Vitamin B12 deficiency. The folate deficiency was highest among neuropsychiatric patients with or without HIV infection and Vitamin B12 deficiency was higher among HIV patients with TB.
