Review of Malaria Situation in Assam with Special Reference to Security Forces

Assam, alone, with 2.6% of the country’s population, contributes > 5% of the total malaria cases in the country. Keeping in view the importance of malaria in the North East and its special significance to the Armed Forces the present study was undertaken to review the malaria situation in Assam.Data on commonly used parameters of malaria surveillance including drug resistance from 2000 to 2008 were collected. Subsequently the extensive data was compiled in the form of Malaria Atlas Of Assam with choroplath maps at district and PHC level. The number of hospital admissions due to malaria in various service hospitals post 2009 have been taken as an index to measure the success of focused interventions.District wise mean API of Assam is depicted in Table 1 whereas District wise pattern of reported chloroquine resistance is presented in Figure 1 [4] Total number of admissions due to malaria (both P Vivax and P falciparum species) in service hospitals in the state of Assam for the period 2000 to 2008 is depicted in Table 2. Month wise distribution of cases of malaria in a particular Army field formation (where the revised focused intervention strategy was first implemented) for the year 2009 along with type of infection is given in Table 3.The service personnel deployed in NE region are especially vulnerable as they share the same anthropoecosystem as that of local population but at the same time lack the partial immunity to malaria enjoyed by local population[1].The data collated by us has shown that the patterns of malaria incidence are not uniform across the state and varies considerably even within the same District. Having API based choroplath maps upto PHC level is of great value for malaria risk assessment for the security forces

A randomized, comparative, open clinical trial for evaluating the efficacy of PP/JLN/107/09-10 Syrup in the management of Functional Constipation

Context: Functional constipation which has no underlying organic causes is difficult to be allopathic treatment for long term due to its side effects and undeniable effect, thus a natural balanced and compatible formulation needs to be validated. Objectives: Current study aimed to assess a poly-herbal formulation in management of functional constipation. Material and Methods: This study was 28 days, two armed, randomized, open labeled, prospective clinical study. 60 clinically confirmed cases of functional constipation patients randomized to receive orally either 2 teaspoonful of PP/JLN/107/09-10 Syrup or 1 teaspoonful of 5- 6 gm of Isabgol powder. Results were analyzed as per Rome II criteria and other associated symptoms like headache, acidity, belching, barborgysmy, flatulence and abdominal distension or bloating which are recorded on VAS score. Results: PP/JLN/107/09-10 scored over Isabgol on four out of six parameters of Rome II Criteria viz., frequency of bowel movement, straining at defecation, lumpy I hardstool formation, feeling of incomplete evacuation, feeling of ano-rectal blockage and manual maneuvers (p < 0.001). Trial drugs showed comparable effects (p > 0.05) in reducing the mean scores of associated symptoms like headache, acidity, belching, borgorgysmy, flatulence and abdominal distension. However, trial drug was found to perform statistically significant result in more number of parameters in comparison to Isabgol. Conclusion: PP/JLN/107/09-10 was found to be effective and safe in reliving functional constipation

Caucasian and Asian Specific Rheumatoid Arthritis Risk Loci Reveal Limited Replication and Apparent Allelic Heterogeneity in North Indians

Genome-wide association studies and meta-analysis indicate that several genes/loci are consistently associated with rheumatoid arthritis (RA) in European and Asian populations. To evaluate the transferability status of these findings to an ethnically diverse north Indian population, we performed a replication analysis. We investigated the association of 47 single-nucleotide polymorphisms (SNPs) at 43 of these genes/loci with RA in a north Indian cohort comprising 983 RA cases and 1007 age and gender matched controls. Genotyping was done using Infinium human 660w-quad. Association analysis by chi-square test implemented in plink was carried out in two steps. Firstly, association of the index or surrogate SNP (r2>0.8, calculated from reference GIH Hap-Map population) was tested. In the second step, evidence for allelic/locus heterogeneity at aforementioned genes/loci was assessed for by testing additional flanking SNPs in linkage equilibrium with index/surrogate marker

Targeted gene sanger sequencing should remain the first-tier genetic test for children suspected to have the five common X-linked inborn errors of immunity

DATA AVAILABILITY STATEMENT : The original contributions presented in the study are included in the article/Supplementary Material. Further inquiries can be directed to the corresponding author.To address inborn errors of immunity (IEI) which were underdiagnosed in resource-limited regions, our centre developed and offered free genetic testing for the most common IEI by Sanger sequencing (SS) since 2001. With the establishment of The Asian Primary Immunodeficiency (APID) Network in 2009, the awareness and definitive diagnosis of IEI were further improved with collaboration among centres caring for IEI patients from East and Southeast Asia. We also started to use whole exome sequencing (WES) for undiagnosed cases and further extended our collaboration with centres from South Asia and Africa. With the increased use of Next Generation Sequencing (NGS), we have shifted our diagnostic practice from SS to WES. However, SS was still one of the key diagnostic tools for IEI for the past two decades. Our centre has performed 2,024 IEI SS genetic tests, with in-house protocol designed specifically for 84 genes, in 1,376 patients with 744 identified to have disease-causing mutations (54.1%). The high diagnostic rate after just one round of targeted gene SS for each of the 5 common IEI (X-linked agammaglobulinemia (XLA) 77.4%, Wiskott–Aldrich syndrome (WAS) 69.2%, X-linked chronic granulomatous disease (XCGD) 59.5%, X-linked severe combined immunodeficiency (XSCID) 51.1%, and X-linked hyper-IgM syndrome (HIGM1) 58.1%) demonstrated targeted gene SS should remain the first-tier genetic test for the 5 common X-linked IEI.The Hong Kong Society for Relief of Disabled Children and Jeffrey Modell Foundation.http://www.frontiersin.org/Immunologyam2023Paediatrics and Child Healt

Molecular diagnosis of 46, XY DSD and identification of a novel 8 nucleotide deletion in exon 1 of the SRD5A2 gene

Phenotypic presentation of 46,XY DSD depends on the underlying defects. Defect in androgen action on the target tissues or production of active metabolite share common morphological features. Molecular study may help differentiating these abnormalities with precision. Mutational analysis of androgen receptor (AR) and SRD5A2 genes was performed in 29 subjects with 46,XY DSD, by PCR-SSCP. The amplicons that showed an aberrant migration in SSCP were subjected to sequencing. Interestingly, six patients from 4 unrelated families (a pair of sibs, uncle/nephew and other two isolated) were identified with mutations in SRD5A2 gene. In five patients p.R246Q missense mutation was detected, of which four were homozygous and one was compound heterozygous: g.80_87delT CGCGAAG (p.A27fsX132) and p.R246Q. Another patient with isolated micropenis harbored a heterozygous p.G196S missense mutation. No AR gene mutation was detected. In conclusion, our study suggests that p.R246Q mutation is common amongst patients with SRD5A2 gene defect from the Northern states of India. Also, it records a novel deletion in exon 1 of SRD5A2 gene in a patient with severe hypospadias

Aetiology of anaphylaxis in patients referred to an immunology clinic in Colombo, Sri Lanka

Abstract Background The aetiology of anaphylaxis differs according to types of foods consumed, fauna and foliage and cultural practices. Although the aetiology of anaphylaxis in Western countries are well known, the causes in South Asian countries have not been reported. We sought to determine the causes of anaphylaxis in patients referred to an immunology clinic in Colombo, Sri Lanka. Methods 238 episodes of anaphylaxis were reviewed in 188 patients who were referred and skin prick tests and in vitro tests (ImmunoCap) were carried out to assess the presence of allergen specific IgE. Clinical features and severity of anaphylaxis was also recorded along with treatment received. Results Anaphylaxis to food either following direct exposure 90/238 (37.5%) or after exercise in the form of food dependent exercise induced anaphylaxis 29/238 (12.2%) was the predominant cause of anaphylaxis. Allergy to cow’s milk and red meat, after immediate exposure, accounted for 66/238 (27.7%) of instances of all episodes of anaphylaxis and 66/90 (73.33%) of anaphylaxis due to food. Vaccines accounted for 28/238 (11.8%) of instances of anaphylaxis, especially among children. Of those who developed anaphylaxis to the MMR (n = 14), 71.4% of them had specific IgE to cow’s milk and 35.7% of them had specific IgE to beef. Of those who developed anaphylaxis to insect stings, 27/42 of these episodes occurred following stings of ants (family Formicidae). The predominant cause of anaphylaxis changed with the age, with food allergy being the most frequent trigger of anaphylaxis in childhood, while drug allergy and idiopathic anaphylaxis being more frequent after 30 years of age. Conclusions In this cohort, anaphylaxis to red meat appears to be the predominant cause of food induced anaphylaxis and presence of beef specific IgE and cow’s milk, appears to be a predisposing factor for vaccine induced anaphylaxis

Thyroxine replacement therapy reverses sleep-disordered breathing in patients with primary hypothyroidism

Background and purpose Anecdotal reports suggest that sleep-disordered breathing (SDB) is common among patients with primary hypothyroidism. This study was undertaken to determine the prevalence of SDB and to evaluate the effect of thyroxine replacement therapy on SDB in patients with primary hypothyroidism. Patients and methods Fifty consecutive newly diagnosed, untreated symptomatic patients with primary hypothyroidism (age:34±11 years; males: 21 [42%]) were prospectively studied. Physical examination, anthropometry, fasting blood glucose and serum lipids were performed in all patients at baseline. Polysomnography was done at baseline in all patients and was repeated after adequate thyroxine replacement in those who had SDB. Results SDB defined as apnea-hypopnea index (AHI) ≥5 was present in 15 patients (30%) at baseline and was reversible in 10 of the 12 patients evaluated following thyroxine replacement therapy (P=0.006). Thyroxine replacement therapy was associated with improvement in findings that reflect a compromised upper airway, such as macroglossia (4 [33%] vs. 1 [8%]; P=0.083), myoedema (5 [42%] vs. 1 [8%]; P=0.046) and facial puffiness (10 [83%] vs. 1 [8%]; P=0.003). Conclusions Reversible SDB is common among patients with primary hypothyroidism. Changes in upper airway anatomy resulting from hypothyroidism probably contribute to the development of SDB in these patients

Poliovirus excretion among persons with primary immune deficiency disorders: summary of a seven-country study series.

International audiencePersons with primary immune deficiency disorders (PID), especially those disorders affecting the B-cell system, are at substantially increased risk of paralytic poliomyelitis and can excrete poliovirus chronically. However, the risk of prolonged or chronic excretion is not well characterized in developing countries. We present a summary of a country study series on poliovirus excretion among PID cases. Cases with PID from participating institutions were enrolled during the first year and after obtaining informed consent were tested for polioviruses in stool samples. Those cases excreting poliovirus were followed on a monthly basis during the second year until 2 negative stool samples were obtained.A total of 562 cases were enrolled in Bangladesh, China, Iran, Philippines, Russia, Sri Lanka, and Tunisia during 2008-2013. Of these, 17 (3%) shed poliovirus, including 2 cases with immunodeficient vaccine-derived poliovirus. Poliovirus was detected in a single sample from 5/17 (29%) cases. One case excreted for more than 6 months. None of the cases developed paralysis during the study period.Chronic polioviruses excretion remains a rare event even among individuals with PID. Nevertheless, because these individuals were not paralyzed they would have been missed by current surveillance; therefore, surveillance for polioviruses among PID should be established
