Identification and treatment of Nepal 2015 earthquake survivors with posttraumatic stress disorder by nonspecialist volunteers: An exploratory cross-sectional study.

CONTEXT: In April 2015, a major earthquake struck northern regions of Nepal affecting one-third of the population, and many suffered mental health problems. AIMS: This study aimed to conduct a preliminary investigation of prevalence and feasibility of brief therapy for posttraumatic stress disorder (PTSD) among earthquake survivors. SETTINGS AND DESIGN: This is an exploratory cross-sectional study of prevalence and feasibility of brief trauma-focused therapy for PTSD among survivors 3 and 11 months after the earthquake in affected areas near Kathmandu. METHODOLOGY: A team of local nonspecialist mental health volunteers was trained to identify survivors with PTSD using the PTSD checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PCL-5) (cutoff score 38). They were trained to deliver either shortened versions of narrative exposure therapy (NET)-revised or group-based control-focused behavioral treatment (CFBT). RESULTS: Altogether, 333 survivors were surveyed (130 in July 2015 and 203 in March 2016) with PCL-5 as the screening instrument, using the cutoff score of 38 or more for diagnosing PTSD. A PTSD prevalence of 33% was noted in 2015 and 28.5% in 2016. This drop of 4.5% prevalence in the intervening 8 months suggests that a significant number of survivors are still suffering from PTSD. Most participants were female, aged 40 or above, married, and poorly educated. Compared to the brief (four sessions) individual NET-revised, a group-based CFBT was found more acceptable and affordable. CONCLUSIONS: PTSD is common following earthquake trauma, and if untreated, survivors continue to suffer for a long time. Management of PTSD should be included in future disaster management plans.

Multi drug resistance and Extended Spectrum Beta Lactamases in clinical isolates of Shigella: A study from New Delhi, India.

BACKGROUND: Shigella is an important cause of gastroenteritis in local Indian population, as well as of traveler's diarrhea in the international visitors to India. These patients often require appropriate antimicrobial therapy; however, rapid development of antimicrobial resistance poses a major hurdle in achieving this goal. METHOD: A prospective study was conducted during 2009-12 in New Delhi, India, including 6339 stool samples from gastroenteritis patients. 121 Shigella strains were identified on the basis of colony morphology, biochemical reactions, serotyping and ipaH gene based PCR. Antimicrobial susceptibility testing by disc diffusion, MIC determination by Vitek(®) 2 and phenotypic tests for ESBL/AmpC production were done. RESULTS: Nineteen percent strains (23/121) were found to be resistant to third generation cephalosporins and all were phenotypically confirmed to be ESBL producers; one strain was positive for AmpC. ESBL producing strains were also found to be significantly more resistant (p < 0.05) to several other antimicrobials agents in comparison to ESBL non-producers, [ampicillin (100% vs. 62.2%), ampicillin/sulbactam (100% vs. 30.6%), cotrimoxazole (100% vs. 77.6%), ciprofloxacin (87.0% vs. 49.0%), ofloxacin (87.0% vs. 52.0%) and gentamicin (30.4% vs. 7.1%)]. Multidrug resistance was seen in 76% strains. CONCLUSIONS: Inappropriate use of antimicrobial agents puts high selection pressure on the higher-end antibiotics. Multi-drug resistance and high rates of ESBL production by Shigella is a matter of concern for the local population as well as international travelers. Therefore, better national level antimicrobial management programs are the priority needs.

A comparative study of conventional and molecular techniques in diagnosis of campylobacter gastroenteritis in children.

BACKGROUND: Campylobacter species are a significant cause of gastroenteritis among children worldwide. Conventional methods for detection of Campylobacter spp. based on cultural isolation and biochemical tests are cumbersome and time consuming. Because of their superior sensitivity and cost effectiveness, molecular methods are often used for identification of the pathogens. AIMS: To evaluate different diagnostic methods for identification of Campylobacter. MATERIALS AND METHODS: Faecal samples were collected from 585 children (age ≤ 12 years) with acute diarrhoea admitted in a tertiary-care hospital, excluding children already on antimicrobial therapy. All samples were examined by four methods: Grams' staining, culture methods, Enzyme-Immuno Assay, and Polymerase Chain Reaction (PCR). After Grams' staining, samples were inoculated on modified charcoal cefoperazone deoxycholate agar. ProSpecT™ Microplate Assay® and PCR assay using cadF gene was done for detection of Campylobacter specific antigen and DNA, respectively, in faecal samples. McNemar's test was used to compare the results wherever applicable. RESULTS: 197 cases (33.67%) were found to be positive for Campylobacter by at least one method. But only 121 (20.78%) out of the 585 stool specimens tested fulfilled the positivity criteria, i.e., positive either by culture or by any two tests among other three. Culture had very low sensitivity (37.19%), whereas PCR had the highest (96.69%) sensitivity but lowest positive predictive value (86.03%). Rapid Grams' staining technique (sensitivity 63.64%) was found to be better than culture. Detection by PCR and ELISA was significantly better than by culture on selective media and Grams' staining (p<0.0001). CONCLUSIONS: Molecular techniques significantly increased detection rates of Campylobacter in children with diarrhoea. However, enzyme-immuno assay with high accuracy has the advantage of applicability in resource-poor settings.

A comparison of nested PCR assay with conventional techniques for diagnosis of intestinal cryptosporidiosis in AIDS cases from northern India.

Cryptosporidiosis is a very important opportunistic infection and is responsible for significant morbidity and mortality in HIV/AIDS patients. Although current laboratory methods are generally considered adequate to detect high concentrations of oocysts, they fail to detect cases of cryptosporidiosis in many immunocompromised patients. The present study was done to determine the diagnostic efficacy of modified Ziehl-Neelsen (ZN), antigen detection ELISA, and a nested PCR assay for detection of Cryptosporidium in 58 adult AIDS cases with diarrhea from the ART clinic of Lok Nayak Hospital, New Delhi. Cryptosporidium was detected in 17 (29.4%), 39 (67.3%), and 45 (77.5%) cases by modified ZN staining, antigen ELISA, and nested PCR assay, respectively. Taking nested PCR as the gold standard, specificity of both modified ZN staining and Cryptosporidium antigen detection ELISA was 100% while the sensitivity of the tests was 37.8% and 86.6%, respectively. PCR was more sensitive than the other two diagnostic modalities but required a more hands-on time per sample and was more expensive than microscopy. PCR, however, was very adaptable to batch analysis, reducing the costs considerably. This assay can therefore have considerable advantages in the treatment of immunosuppressed individuals like AIDS patients, allowing their early diagnosis and decreasing the morbidity and the mortality.

Enteric pathogens, immune status and therapeutic response in diarrhea in HIV/AIDS adult subjects from north India.

Intestinal infection causing diarrheal disease is a dominant contributor to high morbidity and mortality in developing countries. This intervention study aimed to assess the response of specific anti-microbial and anti-retroviral therapy (ART) on enteropathogens identified in HIV/AIDS adult subjects from northern India. Seventy five ART naive (group 1) and seventy five ART adherent (group 2) HIV/AIDS adult subjects with diarrhea were enrolled. Stool samples from all subjects were examined for enteropathogens by wet mount, staining methods, culture and ELISA. Subjects with enteropathogens were started on specific therapy as per National AIDS Control Organisation, Government of India's guidelines. Follow-up stool samples were examined after 2-4 weeks of completion of therapy for persistence/clearing of enteropathogens. CD4+ T lymphocyte count was done for all subjects. At enrollment, group 1 had 26.13% bacterial, 57.66% parasitic & 16.22% fungal pathogens while group 2 had 11.9%, 69.05% & 19.05% pathogens, respectively. Parasitic diarrhea was more common than bacterial diarrhea. The coccidian parasites (Cryptosporidium spp. & Isospora belli) were the common parasites identified. Clearance of enteric pathogens was significant after specific anti-microbial therapy (p = 0.0001). Persistence of enteropathogens was seen primarily for coccidian parasites. Clearance of enteropathogens after specific therapy and the diagnostic yield of stool specimens were influenced by the CD4+ counts. Immune competence coupled with specific anti-microbial therapy displays the best response against enteric pathogens.

Increasing antimicrobial resistance of campylobacter jejuni isolated from paediatric diarrhea cases in a tertiary care hospital of new delhi, India.

INTRODUCTION: The resistance to the clinically important antimicrobial agents, particularly the fluoroquinolones and the macrolides, is increasing among the Campylobacter isolates. Only limited data is available regarding the changing antimicrobial resistance pattern in the Indian scenario. METHODOLOGY: Three hundred fifty cases (ages ≤12years) of acute diarrhoea, who were admitted to a tertiary-care hospital, were investigated for Campylobacter spp. The antimicrobial susceptibilities of all the C. jejuni isolates were assessed by the disk diffusion method according to the CLSI guidelines. RESULTS: A total of 36 isolates of C. jejuni were tested for their antimicrobial susceptibilities. A high degree of resistance to the fluoroquinolones (100% to Nalidixic acid and 86.66% to Ciprofloxacin) was detected in the Campylobacter isolates. The frequency of resistance against Tetracycline was 33.33% and that against Erythromycin was 22.2%. Fifteen (41.66%) isolates were multiresistant, being resistant to 3 or more antimicrobial agents. CONCLUSIONS: An increased resistance to the quinolones and the macrolides and multidrug resistance warrant a reconsideration of their use as the drugs of choice in patients with severe gastroenteritis when Campylobacter is the presumed cause.

Dementia assessment and management protocol for doctors in Nepal.

WHO Dementia Report published in 2012 highlighted the exponential rise of dementia in the elderly population worldwide, especially in low-and middle-income countries. There may be over 135,000 people with dementia in Nepal, but there are no formal arrangements for diagnosis and treatment or any care and support for their caregivers. WHO developed the Mental Health Gap Action Programme (mhGAP) Intervention Guide in 2010, for mental, neurological and substance use, including dementia in non-specialist health settings. This paper reviews the current dementia care provisions in Nepal and proposes a mhGAP-based dementia assessment and management protocol for Nepalese doctors in hospital/clinic settings. The protocol also outlines a post-diagnostic advice for dementia caregivers. The protocol would be discussed at various stakeholders meetings before recommending for routine clinical use.

Disease progression and antiretroviral therapy in newly seropositive HIV subjects in a tertiary care hospital in North India.

INTRODUCTION: In developing countries the standard methods used to monitor HIV disease progression and therapy response are clinical assessment, CD4+ T lymphocyte count measurement, and plasma viral load (PVL) quantification. These tests require expensive equipment and skilled technicians, so monitoring HIV in resource-limited countries remains challenging as few laboratories can offer these tests free of cost. METHODOLOGY: Newly diagnosed HIV seropositive subjects (n = 130) were categorized into three study groups: CD4 counts < 200 cells/µl (group A, 43 subjects); 200-500 cells/µl (group B, 44 subjects); and > 500 cells/µl (group C, 43 subjects). At recruitment, PVL estimation was performed for group A subjects only, who were then initiated on highly active antiretroviral therapy (HAART) and were followed up after six months for evaluation of response to HAART by measuring the CD4 counts and PVL. Groups B and C were followed up after six months to monitor disease progression by measuring only CD4 counts. RESULTS: Among group A subjects, a rise in the median CD4 counts after six months of HAART was observed. At baseline, PVL ranged from 2636 to > 750,000 copies/ml with a median PVL at baseline of 165,000 copies/ml. At follow-up, 90% of the study subjects had undetectable levels of viraemia. Among group B and C subjects, a fall in the CD4 counts at follow-up was observed. CONCLUSIONS: CD4 count is a powerful tool to determine response to antiretroviral therapy (ART) and monitor disease progression in HIV/AIDS. PVL is important to assess response to ART, especially in immunovirologic discordant responses.

Effectiveness of a recovery-orientated psychiatric intervention package on the wellbeing of people with early dementia: a preliminary randomised controlled trial.

OBJECTIVE: To investigate whether recovery-orientated psychiatric assessment and therapeutic intervention enhances the wellbeing of people with dementia and their family carers. METHODS: In a preliminary randomised controlled trial, 48 people with early dementia were recruited. Of 34 who completed the trial, 17 were in the recovery and 17 in the treatment as usual group. Recovery participants received a recovery-focused pre-diagnostic wellbeing assessment and counselling, diagnostic consultation with written feedback and post-diagnostic support over a period of 6 months using the WHO Wellbeing Index as the primary measure, and Mini Mental State Examination, Cornell Scale for Depression in Dementia, EUROQOL and Zarit Burden Interview as secondary outcome measures. RESULTS: People in the recovery group showed a significant improvement in the WHO Wellbeing Index (18.3 for recovery vs 9.46 for treatment as usual; t = -2.28, p = 0.03), with trends of improvement in other outcome measures. CONCLUSIONS: This trial shows that a recovery-focused diagnostic consultation and post-diagnostic support enhance the wellbeing of people with mild cognitive impairment and early dementia.

Clinical and Microbiological Profile of HIV/AIDS Cases with Diarrhea in North India.

Intestinal infections are a significant cause of morbidity and mortality in people living with HIV/AIDS (PLWHA) especially in developing countries. The present study was conducted to assess the clinical and microbiological spectrum in HIV/AIDS cases with diarrhea and to correlate the occurrence of such pathogens with stool characters, HIV seropositivity status, and CD4 counts. Stools from 154 HIV seropositive subjects and 50 HIV negative controls were examined by direct microscopy, fecal cultures, and serological tests (Clostridium difficile Toxin A, Cryptosporidium antigen, and Entamoeba histolytica antigen ELISA). CD4 T cell enumeration was done using FACS count (Becton Dickinson). The study showed a male preponderance (112 males and 42 females). Weakness, abdominal pain, and anorexia were the most common symptoms. Coccidian parasites were the most common cause of diarrhea in HIV seropositive cases. C. parvum was seen in 60.42% while Isospora belli in 9.03%. Amongst the bacterial pathogens C. difficile was detected in 18.06%, diarrheagenic Escherichia coli in 11.11%, and Shigella spp. in 2.78%. Pathogen isolation rates were more in HIV seropositive cases and subjects with low CD4 T lymphocyte counts. Regular monitoring of CD4 T lymphocyte counts and screening for enteric pathogens will help improve the quality of life for PLWHA.

Hepatitis B infection in microbiology laboratory workers: prevalence, vaccination, and immunity status.

The risk of contracting HBV by health care workers (HCW) is four-times greater than that of general adult population. Studies have demonstrated that vaccine-induced protection persists at least 11 years. High risk groups such as HCWs should be monitored and receive a booster vaccination if their anti-HBsAb levels decrease below 10 mIU/mL. In view of the above this study was undertaken to assess the HBV vaccination of the HCWs and their immunological response. Seventy-two HCWs of the Department of Microbiology, Maulana Azad Medical College, New Delhi, India, were recruited and blood sample was drawn for serological tests (HBSAg, anti-HCV, anti-HBsAb, anti-HBeAb, and anti-HBcAb). Anti-HBs titers of >10 mIU/mL were considered protective. Thirty-four (47.3%) of the participants were completely vaccinated with three doses. 25 (73.5%) of the participants with complete vaccination had protective anti-HBsAb levels as against 8 (53.3%) of those with incomplete vaccination and 9 (39.1%) of those who were not vaccinated at all. One of our participants was acutely infected while 29 participants were susceptible to infection at the time of the study. All HCWs should receive three doses of the vaccine and be monitored for their immune status after every five years. Boosters should be administered to those who become susceptible.

Nepal: trying to reach out to the community.

Sandwiched between India and China, Nepal is a small landlocked lower-middle-income country in South Asia. Once a peaceful country, it is striving to overcome the legacy of a 10-year Maoist rebellion, a royal massacre and continuing political chaos. Nepal has been in dispute with neighbouring Bhutan over the repatriation of hundreds of thousands of refugees in several camps in Nepal. In addition, the country experiences frequent natural disasters (floods and landslides) and faces several environmental challenges, including deforestation and a population explosion in southern Nepal.
