Management of malaria in pregnancy
Stephen J Rogerson
September 2017, 146(3):328-333
DOI:10.4103/ijmr.IJMR_1304_17  PMID:29355138
Pregnant women are especially susceptible to malaria infection. Without existing immunity, severe malaria can develop requiring emergency treatment, and pregnancy loss is common. In semi-immune women, consequences of malaria for the mother include anaemia while stillbirth, premature delivery and foetal growth restriction affect the developing foetus. Preventive measures include insecticide-treated nets and (in some African settings) intermittent preventive treatment. Prompt management of maternal infection is key, using parenteral artemisinins for severe malaria, and artemisinin combination treatments (ACTs) in the second and third trimesters of pregnancy. ACTs may soon also be recommended as an alternative to quinine as a treatment in the first trimester of pregnancy. Monitoring the safety of antimalarials and understanding their pharmacokinetics is particularly important in pregnancy with the altered maternal physiology and the risks to the developing foetus. As increasing numbers of countries embrace malaria elimination as a goal, the special needs of the vulnerable group of pregnant women and their infants should not be overlooked.

The molecular basis of the blood group antigens was identified first in the 1980s and 1990s. Since then the importance of molecular biology in transfusion medicine has been described extensively by several investigators. Molecular genotyping of blood group antigens is one of the important aspects and is successfully making its way into transfusion medicine. Low-, medium- and high-throughput techniques have been developed for this purpose. Depending on the requirement of the centre like screening for high- or low-prevalence antigens where antisera are not available, correct typing of multiple transfused patients, screening for antigen-negative donor units to reduce the rate of alloimmunization, etc. a suitable technique can be selected. The present review discusses the evolution of different techniques to detect molecular genotypes of blood group systems and how these approaches can be used in transfusion medicine where haemagglutination is of limited value. Currently, this technology is being used in only a few blood banks in India. Hence, there is a need for understanding this technology with all its variations.

Shankar Prinja, Deepak Balasubramanian, Gursimer Jeet, Ramesh Verma, Dinesh Kumar, Pankaj Bahuguna, Manmeet Kaur, Rajesh Kumar
September 2017, 146(3):354-361
DOI:10.4103/ijmr.IJMR_902_15  PMID:29355142
Background & objectives: Despite an impetus for strengthening public sector district hospitals for provision of secondary health care in India, there is lack of robust evidence on cost of services provided through these district hospitals. In this study, an attempt was made to determine the unit cost of an outpatient visit consultation, inpatient bed-day of hospitalization, surgical procedure and overall per-capita cost of providing secondary care through district hospitals. Methods: Economic costing of five randomly selected district hospitals in two north Indian States - Haryana and Punjab, was undertaken. Cost analysis was done using a health system perspective and employing bottom-up costing methodology. Quantity of all resources - capital or recurrent, used for delivering services was measured and valued. Median unit costs were estimated along with their 95 per cent confidence intervals. Sensitivity analysis was undertaken to assess the effect of uncertainties in prices and other assumptions; and to generalize the findings for Indian set-up. Results: The overall annual cost of delivering secondary-level health care services through a public sector district hospital in north India was ' 11,44,13,282 [US Dollars (USD) 2,103,185]. Human resources accounted for 53 per cent of the overall cost. The unit cost of an inpatient bed-day, surgical procedure and outpatient consultation was ' 844 (USD 15.5), ' 3481 (USD 64) and ' 170 (USD 3.1), respectively. With the current set of resource allocation, per-capita cost of providing health care through district hospitals in north India was ' 139 (USD 2.5). Interpretation & conclusions: The estimates obtained in our study can be used for Fiscal planning of scaling up secondary-level health services. Further, these may be particularly useful for future research such as benefit-incidence analysis, cost-effectiveness analysis and national health accounts including disease-specific accounts in India.

Dipak Dilip Chaudhari, Rajbir Singh, Rashmi Hogarehalli Mallappa, Namita Rokana, Jai Kumar Kaushik, Rajesh Bajaj, Virender Kumar Batish, Sunita Grover
September 2017, 146(3):409-419
DOI:10.4103/ijmr.IJMR_802_15  PMID:29355150
Background & objectives: Milk proteins play a beneficial role in the regulation of food intake, postprandial glycaemia and enteroendocrine hormone secretions and thus are receiving considerable attention for the management of metabolic inflammatory disorders such as type 2 diabetes mellitus (T2DM). The objective of this study was to evaluate the efficacy of peptide/s obtained from milk proteins (casein and whey) as well as from the milk fermented with Lactobacillus helveticus as secretagogues for gut hormones and to purify and characterize the active peptides. Methods: Effect of hydrolysates of casein protein (CP) and whey protein (WP) and L. helveticus fermented milk on the expression of proglucagon, pro-gastric inhibitory peptide (GIP) and cholecystokinin (CCK) genes was monitored by real-time quantitative polymerase chain reaction. The active glucagon-like peptide-1 (GLP-1) secretion was also quantitatively measured using ELISA. Results: Hydrolysates of CP and WP as well as fermentates of L. helveticus induced the proglucagon, pro-GIP and CCK expression and secretion of GLP-1 in STC-1 (pGIP/Neo) cells. However, intact casein exhibited maximum GLP-1 secretion and proglucagon expression. Two active peptides (F5 and F7) derived from CP1 and WP3 hydrolysates having the ability to upregulate the GLP-1 secretion by 1.6 and 1.8 folds were obtained, and the mass was found to be 786 and 824 Da, respectively, as determined by electrospray ionization-mass spectrometry. However, no single active peptide from L. helveticus fermented milk could be obtained. Interpretation & conclusions: Casein as well as fermentates obtained from L. helveticus fermented milk showed higher potential for GLP-1 induction. These can be explored as novel therapeutics to T2DM effectively after demonstrating their in vivo efficacy in appropriate animal models.

Interplay of cytokines in preterm birth
Monika Pandey, Mradula Chauhan, Shally Awasthi
September 2017, 146(3):316-327
DOI:10.4103/ijmr.IJMR_1624_14  PMID:29355137
Preterm infants (i.e., born before <37 wk of gestation) are at increased risk of morbidity and mortality and long-term disabilities. Global prevalence of preterm birth (PTB) varies from 5 to 18 per cent. There are multiple aetiological causes and factors associated with PTB. Intrapartum infections are conventionally associated with PTB. However, maternal genotype modulates response to these infections. This review highlights the association of cytokine gene polymorphisms and their levels with PTB. Varying PTB rates across the different ethnic groups may be as a result of genetically mediated varying cytokines response to infections. Studies on genetic variations in tumour necrosis factor-alpha, interleukin-1 alpha (IL-1α), IL-1β, IL-6, IL-10 and toll-like receptor-4 genes and their association with PTB, have been reviewed. No single polymorphism of the studied genes was found to be associated with PTB. However, increased maternal levels of IL-1β and IL-6 and low levels of IL-10 have been found to be associated with PTB.

DOI:10.4103/ijmr.IJMR_1702_15  PMID:29355140
Background & objectives: Cumulus cell co-culture of embryo had been found to be beneficial for achieving better pregnancy and implantation rate (IR). The present study was aimed to evaluate efficiency of cumulus co-culture technique over simple culture of embryo in terms of pregnancy rate (PR) and IR in patients undergoing treatment for infertility using donor oocytes fertilized by intracytoplasmic sperm injection. Methods: This was a quasi-experimental study between control and study groups. The primary endpoint was achievement of pregnancy. Control group included 508 women who underwent embryo development without cumulus cell co-culture and study group included 394 women who underwent embryo development with cumulus cell co-culture using donor's cumulus cells. Results: The present study demonstrated a significant increase in the IR (37.2 vs 24.2%, P<0.001) and in PR (45.7 vs 37.8%, P<0.05) in study group than in control group. The PR and IR were found to be higher in study group, among all groups of women, grouped on the basis of different indications for use of donor oocytes. Interpretation & conclusions: Cumulus cell co-culture technique was found to be more effective than simple culture technique for embryo development in women undergoing treatment for infertility using donor oocytes fertilized by intracytoplasmic sperm injection.

An observational study of incidence, risk factors & outcome of systemic inflammatory response & organ dysfunction following major trauma
Satish Balkrishna Dharap, Sanket Vishnu Ekhande
September 2017, 146(3):346-353
DOI:10.4103/ijmr.IJMR_1538_15  PMID:29355141
Background & objectives: Trauma is known to lead to systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS), which is often a cause of late deaths after injury. SIRS and MODS have been objectively measured using scoring systems. This prospective observational study was carried out in a tertiary care hospital in India to evaluate SIRS and MODS following trauma in terms of their incidence, the associated risk factors and the effect on the outcome. Methods: All adult patients with major life- and limb-threatening trauma were included. Patients who died within 24 h, those with severe head injury, known comorbidity, immunocompromised state, on immunosuppressants or pregnancy were excluded. SIRS and MODS scores were recorded after initial management (baseline score), on days 3 and 6 of admission. SIRS was defined as SIRS score of ≥2 and MODS was defined as MODS score of ≥1. Results: Two hundred patients were enrolled. SIRS was noted in 156 patients (78%). MODS was noted in 145 (72.5%) patients. Overall mortality was 39 (19.5%). Both SIRS and MODS scores were significantly associated with age >60 yr, blunt injury, (lower) revised trauma score hypotension on admission and (higher) injury severity score, but not with gender, pre-hospital time or operative treatment. Interpretation & conclusions: Both SIRS and MODS scores were associated with longer Intensive Care Unit (ICU) stay, more ICU interventions and higher mortality. Incidence of MODS was significantly higher in patients with SIRS. Both scores showed rising trend with time in non-survivors and a decreasing trend in survivors. The serial assessment of scores can help prognosticate outcome and also allocate appropriate critical care resources to patients with rising scores.

Mrinalini Kotru, Rahul Sharma, Suman Kumar Pramanik, Abhishek Purohit, Gurmeet Singh, Avinash Kumar Singh, Deepti Muterja, Pravas Mishra, Tulika Seth, Seema Tyagi, Manoranjan Mahapatra, Hara Prasad Pati, Renu Saxena
September 2017, 146(3):362-368
DOI:10.4103/ijmr.IJMR_195_14  PMID:29355143
Background & objectives: Diagnosis of paroxysmal nocturnal haemoglobinuria (PNH), a rare haematopoietic stem cell disorder, is challenging in patients with bone marrow failure (BMF) syndrome like aplastic anaemia (AA). This study was conducted with the aim to test the efficacy of the newly recommended markers viz. anti-CD16 and CD66b antibody over the existing anti-CD55 and CD59 antibody for PNH diagnosis in India. Methods: This study was conducted on 193 suspected cases of PNH by flow cytometry using lyse wash technique to stain the granulocytes with CD16/CD66b and CD55/CD59. Results: Of the 193 suspected cases, 62 patients showed the presence of PNH clone. Forty six patients were detected by CD55/CD59/CD45, whereas 61 were detected by CD16/CD66b/CD45. CD16/CD66b detected 16 (25.8%) additional patients over CD55/CD59 (P<0.05) and was more sensitive in detecting the PNH clone with higher negative predictive value. Most of the patients (11/16) who were picked up by CD16/CD66b were of AA who had small clone sizes. Further, the PNH clones were more discreetly identified in CD16/CD66b plots than by CD55/CD59. Clone size assessed by CD16/CD66b which reflects the clinical severity of classical PNH (thrombosis/haemolysis), was more representative of the underlying clinical condition than CD55/59. Interpretation & conclusions: In our experience of 62 patients of PNH, CD16/CD66b proved to be more efficacious in detecting PNH. The new panel was especially useful in monitoring PNH associated with BMF which had small clone sizes.

Kumaran Vadivel, Mageshbabu Ramamurthy, Sathish Sankar, Amita Jain, Padma Srikanth, Asit Ranjan Ghosh, Balaji Nandagopal, Aravindan Nair, Gopalan Sridharan
September 2017, 146(3):381-385
DOI:10.4103/ijmr.IJMR_225_16  PMID:29355146
Background & objectives: Parvovirus B19 infections occur worldwide; the infection is acquired early in childhood but could occur later. B19 is reported to cause infection in childhood febrile illnesses, and arthropathies in adults and children and in end-stage renal disease (ESRD) seen in adults. This study was designed to develop an in-house IgM indirect ELISA for serological screening among patients and controls, and to compare ELISA results with those of nested polymerase chain reaction (nPCR) assay. Methods: An in-house IgM indirect ELISA was standardized using peptide sequence of VP1/VP2 region of parvovirus B19. A total of 201 children and adult with febrile illnesses, 216 individuals with non-traumatic arthropathies, 201 cases of chronic anaemia associated with ESRD and 100 healthy controls were tested. Serum was separated from the blood and subsequently used for DNA extraction. The nested polymerase chain reaction (nPCR) for the detection of B19V DNA was performed using primers targeting the overlapping region of VP1/VP2 capsid protein genes. Results: A total of 618 samples were tested for parvovirus B19 by an in-house IgM indirect ELISA. Among these samples, six were positive by in-house ELISA. The inter-rater agreement between ELISA and PCR assays was calculated using kappa coefficient analysis. The value of κ was 0.77 and the strength of agreement was 'good' (P<0.001). Interpretation & conclusions: The in-house IgM indirect ELISA was found to be simple with high sensitivity and specificity when compared with nPCR and could be used as an alternative to expensive commercial kits in resource-poor settings.

Ajanta Sharma, Bornali Sarmah Dutta, Elmy Samsun Rasul, Dipa Barkataki, Anjanamoyee Saikia, Naba Kumar Hazarika
September 2017, 146(3):401-408
DOI:10.4103/ijmr.IJMR_631_15  PMID:29355149
Background & objectives: Although cholera remains to be an important public health problem, studies on reliable population-based estimates of laboratory confirmed cholera in endemic areas are limited worldwide. The aim of this hospital-based study was to evaluate the prevalence of Vibrio cholerae serogroup in Assam, India, during 2003-2013. Methods: Stool samples/rectal swabs were collected from acute watery diarrhoea (AWD) cases during 2003-2013 and processed by standard microbiological procedures. Antibiotic sensitivity test was done following the Clinical and Laboratory Standards Institute guidelines. Year-wise epidemiological trend of cholera was analyzed. Results: Cholera contributed to 3.93 per cent of AWD cases. In Assam, cholera was found to be more prevalent in the rural areas (6.7%) followed by the tea gardens (5.06%), urban slum (1.9%) and urban areas (1.4%). Highest proportion of cholera (13.7%) was observed in 0-10 yr age group. Of them, 11.5 per cent belonged to 0-5 yr age group. V. cholerae O1 El Tor serotype Ogawa was the predominant isolate. Multiple drug-resistant isolates of V. cholerae O1 Ogawa were reported in the study. Interpretation & conclusions: Emergence of resistance amongst V. cholerae towards many antibiotics is a matter of concern. Hence, continuous surveillance for diarrhoeal disorders is necessary to control the future outbreaks of cholera in this region.

Nilanju Pran Sarmah, Kishore Sarma, Dibya Ranjan Bhattacharyya, Ali Sultan, Devendra Bansal, Neeru Singh, Praveen K Bharti, Hargobinder Kaur, Rakesh Sehgal, Pradyumna Kishore Mohapatra, Jagadish Mahanta
September 2017, 146(3):375-380
DOI:10.4103/ijmr.IJMR_291_16  PMID:29355145
Background & objectives: Northeast (NE) India is one of the high endemic regions for malaria with a preponderance of Plasmodium falciparum, resulting in high morbidity and mortality. The P. falciparum parasite of this region showed high polymorphism in drug-resistant molecular biomarkers. However, there is a paucity of information related to merozoite surface protein 1 (msp-1) and glutamate-rich protein (glurp) which have been extensively studied in various parts of the world. The present study was, therefore, aimed at investigating the genetic diversity of P. falciparum based on msp-1 and glurp in Arunachal Pradesh, a State in NE India. Methods: Two hundred and forty nine patients with fever were screened for malaria, of whom 75 were positive for P. falciparum. Blood samples were collected from each microscopically confirmed patient. The DNA was extracted; nested polymerase chain reaction and sequencing were performed to study the genetic diversity of msp-1 (block 2) and glurp. Results: The block 2 of msp-1 gene was found to be highly polymorphic, and overall allelic distribution showed that RO33 was the dominant allele (63%), followed by MAD20 (29%) and K1 (8%) alleles. However, an extensive diversity (9 alleles and 4 genotypes) and 6-10 repeat regions exclusively of R2 type were observed in glurp. Interpretation & conclusions: The P. falciparum population of NE India was diverse which might be responsible for higher plasticity leading to the survival of the parasite and in turn to the higher endemicity of falciparum malaria of this region.

Nishat Hussain Ahmed, Frincy K Baruah, Rajesh K Grover
September 2017, 146(3):420-425
DOI:10.4103/ijmr.IJMR_1362_15  PMID:29355151
Staphylococcus hominis subsp. novobiosepticus is a new sub-species of S. hominis, thus dividing S. hominis into subsp. hominis and novobiosepticus. This study was designed to identify subsp. novobiosepticus isolates amongst the S. hominis isolated from blood samples of patients with malignancy and septicaemia and to study their resistance profile. The identification was performed by using three simple tests which differentiated between the two sub-species. It was found that 22.8 per cent of S. hominis isolates belonged to subsp. novobiosepticus.

Nidhi Singh, Surabhi Gupta, Ravindra M Pandey, Peush Sahni, Shyam S Chauhan, Anoop Saraya
September 2017, 146(3):334-340
DOI:10.4103/ijmr.IJMR_1348_15  PMID:29355139
Background & objectives: Pancreatic cancer has a propensity for wide stromal invasion. Matrix metalloprotease-2 (MMP-2) is a protease that degrades the peri-tumoural tissue and helps in tumour dissemination. Thus, this study was aimed to assess any association of plasma MMP-2 levels with clinicopathological parameters and survival of patients with pancreatic cancer. Methods: Plasma samples from 127 pancreatic cancer patients were analyzed for MMP-2 levels by ELISA. Survival and other clinicopathological parameters of patients were analyzed for any correlation with plasma MMP-2 levels. Results: The mean MMP-2 levels in pancreatic cancer patients were 560.3±222.0 ng/ml which were significantly elevated compared to chronic pancreatitis patients (P<0.001) and healthy individuals (P<0.05). The plasma levels of MMP-2 significantly correlated with tissue expression of this protease (P=0.004). However, MMP-2 levels did not exhibit any association either with clinicopathological parameters or with survival. Interpretation & conclusions: Elevated MMP-2 levels were observed in blood of pancreatic cancer patients which correlated with its tissue expression. However, these levels did not associate with survival or any clinicopathological parameters of patients. Further studies need to be done to confirm the prognostic/ clinical significance of MMP-2 in cancer patients before and after surgery.

Selvaraj Stephen, Stanley Ambroise, Jothimani Pradeep, Dhandapany Gunasekaran, Balakrishnan Sangeetha, Kengamuthu Sarangapani
September 2017, 146(3):386-391
DOI:10.4103/ijmr.IJMR_1815_15  PMID:29355147
Background & objectives: Seroprevalence of Q fever (QF) caused by Coxiella burnetii has been reported from different parts of India. Usually serological/molecular tests are employed for detection of infection. The present study was undertaken to verify the validity of three different QF phase II IgM ELISA kits for acute QF diagnosis by comparing with the gold standard indirect fluorescent antibody assay (IFA). Methods: Fifty eight serum samples collected from 42 patients (26 patients provided acute sample only and 16 both acute and convalescent samples) which were examined by all three commercial kits, were cross-checked with QF Phase II IgM IFA for confirmation. Results: Eleven patients were positive for C. burnetii antibodies by IFA in acute and/or convalescent serum samples. Taking IFA as a reference, percentages of sensitivity, specificity, positive predictive value and negative predictive value for Virion-Serion/Vircell/NovaTec were 36.36, 61.29, 25.00, 73.08; 81.82, 35.48, 31.03, 84.62 and 100, 25.81, 32.35, 100 per cent, respectively. Interpretation & conclusions: The three different ELISA kits exhibited poor agreement amongst them and unacceptable level of false positivity. IFA remains to be the only option for diagnosing acute QF. Discrepancy between the clinical findings and IFA/ELISA results needs confirmation by C. burnetii DNA detection in real-time polymerase chain reaction.

Arvind Valavane, Rama Chaudhry, Pawan Malhotra
September 2017, 146(3):392-400
DOI:10.4103/ijmr.IJMR_623_16  PMID:29355148
Background & objectives: Genomic constitution of the bacterium Legionella pneumophila plays an important role in providing them a pathogenic potential. Here, we report the standardization and application of multiplex polymerase chain reaction (PCR) for the detection of molecular markers of pathogenic potential in L. pneumophila in hospital environment. Methods: Culture of the standard strains of L. pneumophila was performed in buffered charcoal-yeast extract agar with L-cysteine at p H 6.9. Primers were designed for multiplex PCR, and standardization for the detection of five markers annotated to L. pneumophila plasmid pLPP (11A2), lipopolysaccharide synthesis (19H4), CMP-N-acetylneuraminic acid synthetase (10B12), conjugative coupling factor (24B1) and hypothetical protein (8D6) was done. A total of 195 water samples and 200 swabs were collected from the hospital environment. The bacterium was isolated from the hospital environment by culture and confirmed by 16S rRNA gene PCR and restriction enzyme analysis. A total of 45 L. pneumophila isolates were studied using the standardized multiplex PCR. Results: The PCR was sensitive to detect 0.1 ng/μl DNA and specific for the two standard strains used in the study. Of the 45 hospital isolates tested, 11 isolates had four markers, 12 isolates had three markers, 10 isolates had two markers, nine isolates had one marker and three isolates had none of the markers. None of the isolates had all the five markers. Interpretation & conclusions: The findings of this study showed the presence of gene markers of pathogenic potential of the bacterium L. pneumophila. However, the genomic constitution of the environmental isolates should be correlated with clinical isolates to prove their pathogenic potential. Rapid diagnostic methods such as multiplex PCR reported here, for elucidating gene markers, could help in future epidemiological studies of bacterium L. pneumophila.

Ethyl pyruvate improves skin flap survival after ischaemia reperfusion injury
Oguz Kayiran, Suat Sedat Cuzdan, Afsin Uysal, Ugur Kocer
September 2017, 146(3):369-374
DOI:10.4103/ijmr.IJMR_1428_14  PMID:29355144
Background & objectives: Reperfusion after ischaemia is detrimental to the tissues. The oxidative stress created and cytokines released are mostly responsible in this process. In this study, ethyl pyruvate, a known agent for its anti-inflammatory and antioxidant properties, was used to investigate the effects on ischaemia/reperfusion injury on skin island flaps in rats. Methods: Sixty rats were randomly distributed in three groups (non-ischaemic, ischaemic and medication groups). Ethyl pyruvate was administered in the medication group with a dose of 50 mg/kg. After 24 h and one week, the animals were sacrificed, and the flaps were analyzed macroscopically, histopathologically, biochemically (total nitrite, malondialdehyde and myeloperoxidase). Results: Biochemical markers indicating oxidative stress, were found elevated in ischaemic group, whereas medication with ethyl pyruvate significantly reduced these values. There was a significant reduction (P<0.05) in the levels of these markers between ischaemic and medication groups. Ethyl pyruvate improved all the parameters significantly. Interpretation & conclusion: Ethyl pyruvate showed strong scavenger activity against reactive oxygen species. It could be a potential candidate to improve the flap viability in reconstructive microsurgery, especially in free tissue transfers. However, more studies are warranted in experimental models to confirm these findings.
