Unusual non-infectious cause of meningitis.

Meningitis, though commonly caused by various infectious agents, may also have non-infectious aetiologies. The clinical presentation, however may be identical to infectious meningitis. We present a case of a female in her 50s who presented with fever, headache, vomiting and neck rigidity. She had features of inflammatory polyarthritis, cold sensitivity, puffy digits, alopecia and easy fatigability. No evidence of infection was found, and serological features consistent with mixed connective tissue disease (MCTD) were revealed, which led to the diagnosis of MCTD-related aseptic meningitis.

Risk Factors Associated with Diabetic Ketoacidosis at the Onset of Type 1 Diabetes Mellitus.

BACKGROUND: There are various factors which increase the risk of diabetic ketoacidosis at the onset of type 1 diabetes mellitus. There have not been any such studies in our setting. This study was done to find the prevalence and risk factors associated with the development of diabetic ketoacidosis at onset of type 1 diabetes mellitus. METHODS: Children and young adults with type 1 diabetes mellitus being treated at Patan hospital were approached and after obtaining an informed consent, all the patient information on various risk factors for diabetic ketoacidosis were collected in a pre-developed proforma. Data was entered in Microsoft Excel and analysis was done using statistical package for the social sciences-16. Ethical approval was taken from Institutional Review Committee- Patan Academy of Health Sciences. RESULTS: Out of 99 patients with type 1 diabetes enrolled in the study, 52.5% presented in diabetic ketoacidosis at the onset. The duration of symptoms was significantly less in patient presenting with diabetic ketoacidosis than without diabetic ketoacidosis (6.45±7.57 vs 9.13±10.12, p=0.04). There was no significant difference in the mean age, mean glycosylated hemoglobin, mean body mass index, gender, parents' literacy and medical consultations prior to diagnosis. CONCLUSIONS: More than half of the patients with type 1 diabetes presented in diabetic ketoacidosis. The shorter duration of symptoms prior to presentation was the only significant factor leading to presentation as diabetic ketoacidosis.

Clinical remission of rheumatoid arthritis in a multicenter real-world study in Asia-Pacific region.

BACKGROUND: Clinical remission is an attainable goal for Rheumatoid Arthritis (RA). However, data on RA remission rates from multinational studies in the Asia-Pacific region are limited. We conducted a cross-sectional multicentric study to evaluate the clinical remission status and the related factors in RA patients in the Asia-Pacific region. METHODS: RA patients receiving standard care were enrolled consecutively from 17 sites in 11 countries from APLAR RA SIG group. Data were collected on-site by rheumatologists with a standardized case-report form. Remission was analyzed by different definitions including disease activity score using 28 joints (DAS28) based on ESR and CRP, clinical disease activity index (CDAI), simplified disease activity index (SDAI), Boolean remission definition, and clinical deep remission (CliDR). Logistic regression was used to determine related factors of remission. FINDINGS: A total of 2010 RA patients was included in the study, the overall remission rates were 62•3% (DAS28-CRP), 35•5% (DAS28-ESR), 30•8% (CDAI), 26•5% (SDAI), 24•7% (Boolean), and 17•1% (CliDR), respectively, and varied from countries to countries in the Asia-Pacific region. Biological and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) prescription rate was low (17•9%). Compared to patients in non-remission, patients in remission had higher rates of b/tsDMARDs usage and lower rates of GC usage. The favorable related factors were male sex, younger age, fewer comorbidities, fewer extra-articular manifestations (EAM), and use of b/tsDMARDs, while treatment with GC was negatively related to remission. INTERPRETATION: Remission rates were low and varied in the Asia-Pacific region. Treatment with b/tsDMARDs and less GC usage were related to higher remission rate. There is an unmet need for RA remission in the Asia-Pacific region.

Clinicodemographic pattern and treatment outcome of Behcet's disease cases presenting in a tertiary eye center of Nepal.

PURPOSE: To know the clinical and demographic pattern, and the outcome of treatment of Behcet's disease (BD) cases in Nepal METHODS: Retrospective series of all the cases of BD who had come over the period of 12 years (Jan 2007-Dec 2015) Tilganga Institute of Ophthalmology. RESULT: Twenty-one cases were included, 17 (81%) male and four (19%) female. Mean age was 28.88 ± 9.18 years. Mean follow-up period was 3.6 ± 2.6 years. All had nongranulomatous panuveitis. Hypopyon was seen in 13 (61.9%) cases. Small retinal infiltrates in 13 (61.9%) cases and retinal vasculitis in ten (47.6%) cases were seen. Cataract (in 13, 61.9%) and optic atrophy (in 11, 52.4%) cases were present. Oral ulcer was present in 20 (95.2%), genital ulcer in 15 (72%), and skin lesions in 13 (62%) cases. CONCLUSION: BD affected mainly the most active age group and was predominant in male. Optic atrophy was the leading cause of irreversible vision loss. Despite being a less common condition, BD should be considered in the differential diagnosis of panuveitis cases in the Nepalese population.

Azithromycin and cefixime combination versus azithromycin alone for the out-patient treatment of clinically suspected or confirmed uncomplicated typhoid fever in South Asia: a randomised controlled trial protocol.

Background: Typhoid and paratyphoid fever (enteric fever) is a common cause of non-specific febrile infection in adults and children presenting to health care facilities in low resource settings such as the South Asia.  A 7-day course of a single oral antimicrobial such as ciprofloxacin, cefixime or azithromycin is commonly used for its treatment. Increasing antimicrobial resistance threatens the effectiveness of these treatment choices. We hypothesize that combined treatment with azithromycin (active mainly intracellularly) and cefixime (active mainly extracellularly) will be a better option for the treatment of typhoid fever in South Asia. Methods: This is a phase IV, international multi-centre, multi-country, comparative participant-and observer-blind, 1:1 randomised clinical trial. Patients with suspected uncomplicated typhoid fever will be randomised to one of the two interventions: Arm A: azithromycin 20mg/kg/day oral dose once daily (maximum 1gm/day) and cefixime 20mg/kg/day oral dose in two divided doses (maximum 400mg bd) for 7 days, Arm B: azithromycin 20mg/kg/day oral dose once daily (max 1gm/day) for 7 days AND cefixime-matched placebo for 7 days. We will recruit 1500 patients across sites in Bangladesh, India, Nepal and Pakistan. We will assess whether treatment outcomes are better with the combination after one week of treatment and at one- and three-months follow-up. Discussion: Combined treatment may limit the emergence of resistance if one of the components is active against resistant sub-populations not covered by the other antimicrobial's activity. If the combined treatment is better than the single antimicrobial treatment, this will be an important result for patients across South Asia and other typhoid endemic areas. Clinicaltrials.gov registration: NCT04349826 (16/04/2020).

Case Report: Pulmonary tuberculosis and raised transaminases without pre-existing liver disease- Do we need to modify the antitubercular therapy?

We report a case of pulmonary tuberculosis with transaminitis during the presentation but without any pre-existing liver disease or hepatotoxic drug use. This is a fairly common scenario seen in tuberculosis endemic areas; however, this is an under reported condition in the literature and guidelines for its management has not been established. Many clinicians including the authors have treated such cases with modified liver friendly regimens in fear of increasing the hepatotoxicity with standard drugs. However, the modified regimens may not be optimal in treating the underlying tuberculosis. In this report, we gave full dose standard antitubercular drugs, and the liver injury resolved evidenced by normalization of transaminases.

Case Report: Co-existence of sarcoidosis and Takayasu arteritis.

Takayasu arteritis is a rare systemic large vessel vasculitis affecting the aorta and its branches. Sarcoidosis, too, is an inflammatory disease. Both entities are granulomatous conditions with a questionable association in their etiopathogenesis. Only a few cases of their coexistence have been reported in the literature. To our knowledge, no such cases have been reported from Nepal. We report a Nepalese woman who presented with non-productive cough, progressive shortness of breath and chest tightness of 3 years duration. She had a history of recurrent bilateral granulomatous uveitis over the previous 3 years. Examination revealed clubbing of digits, absent pulses over the left radial, ulnar and brachial arteries, and a weak pulse over the right arm including the bilateral carotid arteries. Pulmonary function test showed restrictive pattern, a high-resolution computed tomography (HRCT) scan of the chest revealed findings suggestive of pulmonary sarcoidosis. A CT angiogram suggested large vessel vasculitis. Bronchoscopy with biopsy revealed granulomatous inflammation, negative for malignancy and tuberculosis. She was hence, diagnosed with co-existing Takayasu arteritis and sarcoidosis, and treated with Prednisolone 60 mg once daily with dramatic improvement over 4 days and was discharged stable on domiciliary oxygen. She is currently on azathioprine 50 mg, prednisolone 10 mg without the need for supplemental oxygen. This case report highlights the importance of a proper physical examination as a guide to the use of modern technology in making a correct diagnosis. Furthermore, in countries where tuberculosis is endemic, it should always come as the most important differential diagnosis of granulomatous inflammation.

Adverse events with ayurvedic medicines- possible adulteration and some inherent toxicities.

Ayurvedic medicine, a traditional system of medicine practiced in the Indian subcontinent is considered to be devoid of adverse events. We report three cases which highlight the possibility of adverse events related with the use of ayurvedic products. A 35 year old woman with hepatitis took ayurvedic powder medicine and swarnabhasma (gold salt) and had her liver injury worsened, possibly due to alkaloids, and developed nephrotic syndrome, possibly due to gold salt. A 57 year old hypertensive man was taking ayurvedic medicine containing reserpine which had long been withdrawn from the allopathic system of medicine due to wide range of side effects. A 47 year old woman with rheumatoid arthritis was taking an unknown tablet containing steroid as an adulterant for 2 years and developed side effects typical of steroid excess. We would like to highlight the fact that ayurvedic medicines do have propensity to cause adverse events due to adulteration or inherent constituents like alkaloids, and hence may not always be completely safe.

Poor communication by health care professionals may lead to life-threatening complications: examples from two case reports.

We report two cases which highlight the fact how poor communication leads to dangerously poor health outcome. We present the case of a 50-year-old woman recently diagnosed with rheumatoid arthritis from Southern Nepal presented to Patan hospital with multiple episodes of vomiting and oral ulcers following the intake of methotrexate every day for 11 days, who was managed in the intensive care unit. Similarly, we present a 40-year-old man with ileo-caecal tuberculosis who was prescribed with anti-tubercular therapy (ATT) and prednisolone, who failed to take ATT due to poor communication and presented to Patan Hospital with features of disseminated tuberculosis following intake of 2 weeks of prednisolone alone. These were events that could have been easily prevented with proper communication skills. Improvement of communication between doctors and patients is paramount so that life-threatening events like these could be avoided.

Case Report: Cryptococcal meningitis in an apparently immunocompetent patient in Nepal - challenges in diagnosis and treatment.

A 50 year old woman from Nepal had clinical features suggestive of meningitis. Cerebrospinal fluid (CSF) analysis was normal except for the presence of cryptococcal antigen. The inclusion of test for Cryptococcus in the CSF helped in making the diagnosis of cryptococcal meningitis in our patient who was apparently immunocompetent. Treatment with liposomal amphotericin B could not be started on time due financial constraints. The patient had a stroke and further deteriorated. Liposomal amphotericin B is stocked by the government of Nepal for free supply to patients with visceral leishmaniasis, but the policy does not allow the drug to be dispensed for other infections. The family members of our patient acquired the drug within a few days from a government center using their political connections and following administering the treatment the patient improved. This case demonstrates the utility of considering cryptococcal meningitis as a differential diagnosis, and including tests for Cryptococcus when dealing with immunocompetent patients presenting with meningitis. It also demonstrates the effects of the sociopolitical situation on health care delivery in low- and middle-income countries (LMICs) such as Nepal.

Case Report: Gastric Mucormycosis- a rare but important differential diagnosis of upper gastrointestinal bleeding in an area of Helicobacter pylori endemicity.

A 57 years female from the hills of Nepal presented with upper gastrointestinal bleeding with gastric ulcer evident on endoscopy. Though initially treated with Helicobacter pylori ( H. pylori) eradication therapy alone, biopsy later on revealed both mucormycosis and H. pylori infection. She was then treated with antifungals liposomal amphotericin B followed by posaconazole which led to complete recovery. Mucormycosis is a rare but life-threatening fungal disease of immunocompromised host though our patient was immunocompetent. If recognized and treated at early stage, as in our patient, prognosis is good. A high index of suspicion is required for considering this disease in H. pylori endemic regions such as Nepal, and is crucial for early recognition and treatment.

Gene-Xpert: Diagnosis of Pulmonary Tuberculosis in a Sputum Smear Negative Patient.

This case report has tried to highlight the ease and benefit of Gene-Xpert testing in difficult to diagnose patient with sputum smear negative pulmonary tuberculosis. Early treatment of tuberculosis is usually delayed by lack of rapid and accurate diagnostic modalities, especially in resource-limited settings like ours. Gene-Xpert is a rapid test based on real time PCR assay and molecular technology for the detection of Mycobacterium tuberculosis. It is highly sensitive tool and enables simultaneous detection of rifampicin resistance within short period of time i,e. <2hrs. It has distinct advantage of providing same-day diagnosis which could potentially limit loss to follow up during diagnostic evaluation of smear negative tuberculosis patients. Keywords: Gene-Xpert; pulmonary tuberculosis; sputum microscopy.

Meningitis due to scrub typhus: the importance of a differential diagnosis in an endemic area.

A patient with fever and neck stiffness was treated as partially treated bacterial meningitis based on history, examination and cerebrospinal fluid analysis. After initial improvement with ceftriaxone, vancomycin and dexamethasone, symptoms recurred. Fever resolved promptly after treatment was started with doxycycline, when scrub typhus immunoglobulin M test came positive. Meningitis is a well-known complication of scrub typhus. However, scrub typhus is seldom considered in the differential diagnosis of meningitis in the Indian subcontinent. Early diagnosis and prompt institution of doxycycline therapy may lead to early cure of scrub typhus even when features of meningitis supervene. However, ceftriaxone which is commonly used to treat bacterial meningitis is suboptimal in the treatmenwgt36t of scrub typhus.

Spontaneous hypoglycaemia in a patient with Graves' disease.

A 23-year-old man, on treatment for Graves' disease, presented to the emergency department, with 2 separate episodes of loss of consciousness. During the first episode, the initial serum glucose was 19 mg/mL, and 44 mg/dL during the second episode. The patient was non-diabetic, and had elevated blood insulin, C peptide and insulin antibody levels. His abdominal radiographic findings were normal. He was diagnosed with Hirata disease, and put on propylthiouracil as a replacement for carbimazole. Hypoglycaemia was managed with dextrose infusions and frequent meals. The patient's condition improved and he had no further episodes of hypoglycaemia during the follow-up period.

Paradoxical reaction to antitubercular treatment in a case of pulmonary tuberculosis.

A 51-year-old man presented with intermittent fever, mild cough and loss of appetite of 1-month duration. His sputum smear was positive for acid-fast bacilli and his chest radiograph revealed apical infiltrations. The patient was treated with antitubercular therapy (ATT), recovered and was well for 1 month, after which he suddenly developed focal seizures. MRI of the brain with gadolinium enhancement showed high intensity nodular foci in the frontal, parietal and occipital regions. The patient was diagnosed as a case of paradoxical reaction to ATT, and was successfully managed with continued ATT and adjunctive steroid therapy.

GeneXpert MTB/RIF assay as initial test for diagnosis of tuberculous meningitis.

Tuberculous meningitis (TBM) remains the most dangerous form of tuberculosis with high mortality and potential complications. The prompt diagnosis and treatment of this condition remains a key for better prognosis. A 39-year-old woman presented with severe headache, fever, nausea and vomiting, with a history of headache for a month. On examination, confusion, neck rigidity, ptosis and upward plantar reflexes were present. After 7 days of empiric treatment without resolution of her symptoms, she had another spinal tap performed. The diagnosis of TBM was performed by the GeneXpert MTB/RIF assay from her cerebrospinal fluid (CSF). Antitubercular chemotherapy was started. The patient subsequently improved. Where available, the GeneXpert assay should be used immediately in CSF samples of patients suspected of TBM as an adjunct to clinical algorithms to increase the chance of a prompt diagnosis and treatment.

Patan hospital experience in treating philadelphia chromosome/BCR-ABL1 positive chronic myeloid leukemia patients with gleevec (imatinib mesylate); the first generation specific tyrosine kinase inhibitor.

BACKGROUND: Chronic Myeloid Leukemia (CML) is caused by the abnormal fusion protein BCR-ABL1, a constitutively active tyrosine kinase and product of the Philadelphia chromosome. Gleevec (Imatinib mesylate) is a selective inhibitor of this kinase. Treatment with this agent is known to result in hematologic, cytogenetic, and molecular responses. Patan hospital (Patan, Nepal) is one of the Gleevec International Patient Assistance Program (GIPAP) centers for patients with CML. METHODS: A total of 106 Philadelphia positive CML patients were enrolled in our center between Feb 2003 and Jun 2008, and 103 of them were eligible for cytogenetic and/or hematologic response analyses. RESULTS: Out of 103 patients, 27% patients underwent cytogenetic analysis. Imatinib induced major cytogenetic responses in 89% and complete hematologic responses in almost 100% of the patients with confirmed CML. After a mean follow up of 27 months, an estimated 90% of the patients on imatinib remained in hematologic remission and more than 90% of the patients are still alive. About 30% of patients developed some form of manageable myelosuppression. A few patients developed non-hematologic toxic side effects such as edema and hepatotoxicity. CONCLUSIONS: Our study demonstrates that imatinib is safe to use in a developing country. Furthermore, we demonstrate that imatinib is very effective and induced long lasting responses in a high proportion of patients with Ph chromosome/BCR-ABL1 positive CML. Imatinib is well tolerated by our patients. The lack of cytogenetic analysis in the majority of our patients hindered our ability to detect inadequate responses to imatinib and adjust therapy appropriately.

A patient with paratyphoid A fever: an emerging problem in Asia and not always a benign disease.

A 15-year-old Nepalese boy with fever was thought to have enteric fever and started on cefixime. His blood culture grew Salmonella paratyphoid A. On the sixth day, he developed gastrointestinal bleeding, disseminated intravascular coagulation, and later, acute respiratory distress syndrome. He succumbed to his illness despite treatment in the intensive care unit with ceftriaxone, intravenous fluids, and mechanical ventilation. Salmonella paratyphoid A, for which there is no commercial vaccine, may not be a benign disease as perceived, and cefixime that is recommended for enteric fever may be an ineffective choice.

An open randomized comparison of gatifloxacin versus cefixime for the treatment of uncomplicated enteric fever.

OBJECTIVE: To assess the efficacy of gatifloxacin versus cefixime in the treatment of uncomplicated culture positive enteric fever. DESIGN: A randomized, open-label, active control trial with two parallel arms. SETTING: Emergency Room and Outpatient Clinics in Patan Hospital, Lagankhel, Lalitpur, Nepal. PARTICIPANTS: Patients with clinically diagnosed uncomplicated enteric fever meeting the inclusion criteria. INTERVENTIONS: Patients were allocated to receive one of two drugs, Gatifloxacin or Cefixime. The dosages used were Gatifloxacin 10 mg/kg, given once daily for 7 days, or Cefixime 20 mg/kg/day given in two divided doses for 7 days. OUTCOME MEASURES: The primary outcome measure was fever clearance time. The secondary outcome measure was overall treatment failure (acute treatment failure and relapse). RESULTS: Randomization was carried out in 390 patients before enrollment was suspended on the advice of the independent data safety monitoring board due to significant differences in both primary and secondary outcome measures in the two arms and the attainment of a priori defined endpoints. Median (95% confidence interval) fever clearance times were 92 hours (84-114 hours) for gatifloxacin recipients and 138 hours (105-164 hours) for cefixime-treated patients (Hazard Ratio[95%CI] = 2.171 [1.545-3.051], p<0.0001). 19 out of 70 (27%) patients who completed the 7 day trial had acute clinical failure in the cefixime group as compared to 1 out of 88 patients (1%) in gatifloxacin group(Odds Ratio [95%CI] = 0.031 [0.004 - 0.237], p<0.001). Overall treatment failure patients (relapsed patients plus acute treatment failure patients plus death) numbered 29. They were determined to be (95% confidence interval) 37.6 % (27.14%-50.2%) in the cefixime group and 3.5% (2.2%-11.5%) in the gatifloxacin group (HR[95%CI] = 0.084 [0.025-0.280], p<0.0001). There was one death in the cefixime group. CONCLUSIONS: Based on this study, gatifloxacin is a better treatment for uncomplicated enteric fever as compared to cefixime.
