Mechanisms of Antimicrobial Resistance (AMR) and Alternative Approaches to Overcome AMR

Moo CL, Yang SK, Yusoff K, Ajat M, Thomas W, Abushelaibi A, et al.

Curr Drug Discov Technol, 2020;17(4):430-447.
PMID: 30836923 DOI: 10.2174/1570163816666190304122219

Antimicrobials are useful compounds intended to eradicate or stop the growth of harmful microorganisms. The sustained increase in the rates of antimicrobial resistance (AMR) worldwide is worrying and poses a major public health threat. The development of new antimicrobial agents is one of the critical approaches to overcome AMR. However, in the race towards developing alternative approaches to combat AMR, it appears that the scientific community is falling behind when pitched against the evolutionary capacity of multi-drug resistant (MDR) bacteria. Although the "pioneering strategy" of discovering completely new drugs is a rational approach, the time and effort taken are considerable, the process of drug development could instead be expedited if efforts were concentrated on enhancing the efficacy of existing antimicrobials through: combination therapies; bacteriophage therapy; antimicrobial adjuvants therapy or the application of nanotechnology. This review will briefly detail the causes and mechanisms of AMR as background, and then provide insights into a novel, future emerging or evolving strategies that are currently being evaluated and which may be developed in the future to tackle the progression of AMR.

Fulltext Artemisinin combination therapy fails even in the absence of Plasmodium falciparum kelch13 gene polymorphism in Central India

Das S, Kar A, Manna S, Mandal S, Mandal S, Das S, et al.

Sci Rep, 2021 05 11;11(1):9946.
PMID: 33976269 DOI: 10.1038/s41598-021-89295-0

Artemisinin is the frontline fast-acting anti-malarial against P. falciparum. Emergence and spread of resistant parasite in eastern-India poses a threat to national malaria control programs. Therefore, the objective of our study is to evaluate the artesunate-sulfadoxine-pyrimethamine efficacy in Central India. 180 monoclonal P. falciparum-infected patients received standard ASSP therapy during August 2015-January 2017, soon after diagnosis and monitored over next 42-days. Artemisinin-resistance was assessed through in-vivo parasite clearance half-life (PC1/2), ex-vivo ring-stage survivability (RSA), and genome analysis of kelch13 and other candidate gene (pfcrt, pfmdr1, pfatpase 6, pfdhfr and pfdhps). Of 180 P. falciparum positive patients, 9.5% showed increased PC1/2 (> 5.5 h), among them eleven isolates (6.1%) showed reduced sensitivity to RSA. In 4.4% of cases, parasites were not cleared by 72 h and showed prolonged PC1/2(5.6 h) (P

Fulltext Eradication of Helicobacter pylori infection improves levodopa action, clinical symptoms and quality of life in patients with Parkinson's disease

Hashim H, Azmin S, Razlan H, Yahya NW, Tan HJ, Manaf MR, et al.

PLoS One, 2014;9(11):e112330.
PMID: 25411976 DOI: 10.1371/journal.pone.0112330

BACKGROUND: Previous studies have demonstrated a higher prevalence of Helicobacter pylori (H. pylori) infection in patients with Parkinson's disease (PD) compared to controls. H. pylori infection affects levodopa absorption and its eradication significantly improves clinical response to levodopa. Here, we studied the prevalence of H. pylori infection and its eradication effects among our PD patients.
METHODS: A prospective study involving idiopathic PD patients on levodopa therapy. 13C-urea breath test (UBT) was used to detect H. pylori. UBT-positive patients were given standard eradication therapy and followed up at 6 and 12 weeks in an open label single arm design. Repeat UBT was performed at 12 weeks. The UPDRS, PD NMQ, PD NMSS and PDQ-39 were administered at baseline and post-eradication (6 and 12 weeks). Levodopa 'onset' time and ON-duration were recorded.
RESULTS: Of 82 patients recruited, 27 (32.9%) had positive UBT. H. pylori-positive patients had significantly poorer total UPDRS (p = 0.005) and PDQ39 (p<0.0001) scores compared to H. pylori-negative patients. At 12 weeks post-eradication, the mean levodopa onset time shortened by 14 minutes (p = 0.011). The mean ON duration time increased by 56 minutes at week 6 (p = 0.041) and 38 minutes at week 12 (p = 0.035). The total UPDRS scores (p<0.0001), scores for parts II (p = 0.001), III (p<0.0001) and IV (p = 0.009) were significantly better. The total PDQ-39 scores (p = 0.001) and subdomains mobility (p = 0.002), ADL (p = 0.001), emotional well being (p = 0.026) and stigma (p = 0.034) significantly improved. The PD NMSQ did not show significant improvement.
CONCLUSIONS: H. pylori eradication improved levodopa onset time, ON duration, motor severity and quality of life parameters. Screening and eradication of H. pylori is inexpensive and should be recommended in PD patients, particularly those with erratic response to levodopa.

Fulltext Artesunate-mefloquine versus chloroquine for treatment of uncomplicated Plasmodium knowlesi malaria in Malaysia (ACT KNOW): an open-label, randomised controlled trial

Grigg MJ, William T, Menon J, Dhanaraj P, Barber BE, Wilkes CS, et al.

Lancet Infect Dis, 2016 Feb;16(2):180-188.
PMID: 26603174 DOI: 10.1016/S1473-3099(15)00415-6

BACKGROUND: The zoonotic parasite Plasmodium knowlesi has become the most common cause of human malaria in Malaysia and is present throughout much of southeast Asia. No randomised controlled trials have been done to identify the optimum treatment for this emerging infection. We aimed to compare artesunate-mefloquine with chloroquine to define the optimum treatment for uncomplicated P knowlesi malaria in adults and children.
METHODS: We did this open-label, randomised controlled trial at three district hospitals in Sabah, Malaysia. Patients aged 1 year or older with uncomplicated P knowlesi malaria were randomly assigned, via computer-generated block randomisation (block sizes of 20), to receive oral artesunate-mefloquine (target dose 12 mg/kg artesunate and 25 mg/kg mefloquine) or chloroquine (target dose 25 mg/kg). Research nursing staff were aware of group allocation, but allocation was concealed from the microscopists responsible for determination of the primary endpoint, and study participants were not aware of drug allocation. The primary endpoint was parasite clearance at 24 h. Analysis was by modified intention to treat. This study is registered with ClinicalTrials.gov, number NCT01708876.
FINDINGS: Between Oct 16, 2012, and Dec 13, 2014, we randomly assigned 252 patients to receive either artesunate-mefloquine (n=127) or chloroquine (n=125); 226 (90%) patients comprised the modified intention-to-treat population. 24 h after treatment, we recorded parasite clearance in 97 (84% [95% CI 76-91]) of 115 patients in the artesunate-mefloquine group versus 61 (55% [45-64]) of 111 patients in the chloroquine group (difference in proportion 29% [95% CI 18·0-40·8]; p<0·0001). Parasite clearance was faster in patients given artesunate-mefloquine than in those given chloroquine (18·0 h [range 6·0-48·0] vs 24·0 h [6·0-60·0]; p<0·0001), with faster clearance of ring stages in the artesunate-mefloquine group (mean time to 50% clearance of baseline parasites 8·6 h [95% CI 7·9-9·4] vs 13·8 h [12·1-15·4]; p<0·0001). Risk of anaemia within 28 days was lower in patients in the artesunate-mefloquine group (71 [62%; 95% CI 52·2-70·6]) than in those in the chloroquine group (83 [75%; 65·6-82·5]; p=0·035). Gametocytaemia as detected by PCR for pks25 was present in 44 (86%) of 51 patients in the artesunate-mefloquine group and 41 (84%) of 49 patients in the chloroquine group at baseline, and in three (6%) of 49 patients and two (4%) of 48 patients, respectively, at day 7. Fever clearance was faster in the artesunate-mefloquine group (mean 11·5 h [95% CI 8·3-14·6]) than in the chloroquine group (14·8 h [11·7-17·8]; p=0·034). Bed occupancy was 2426 days per 1000 patients in the artesunate-mefloquine group versus 2828 days per 1000 patients in the chloroquine group (incidence rate ratio 0·858 [95% CI 0·812-0·906]; p<0·0001). One (<1%) patient in the artesunate-mefloquine group had a serious neuropsychiatric event regarded as probably related to study drug.
INTERPRETATION: Artesunate-mefloquine is highly efficacious for treatment of uncomplicated P knowlesi malaria. The rapid therapeutic response of the drug offers significant advantages compared with chloroquine monotherapy and supports a unified treatment policy for artemisinin-based combination therapy for all Plasmodium species in co-endemic areas.

Methotrexate in systemic lupus erythematosus: a systematic review of its efficacy

Sakthiswary R, Suresh E

Lupus, 2014 Mar;23(3):225-35.
PMID: 24399812 DOI: 10.1177/0961203313519159

OBJECTIVE: The objective of this review is to evaluate the evidence for efficacy of methotrexate (MTX) in systemic lupus erythematosus (SLE).
METHODS: A comprehensive, computerized search was performed in MEDLINE (PubMed), EMBASE and the Cochrane Controlled Trials registry to screen for studies that examined the efficacy of MTX in adult SLE patients. The Jadad scoring system was used to assess study quality, and data were pooled using the random effects model.
RESULTS: Of the 53 articles that were identified, 44 were excluded. Nine studies (including three randomized controlled and six observational) were eligible for inclusion. All of the included studies predominantly involved patients with arthritis or mucocutaneous features. There was significant reduction of the SLE Disease Activity Index (SLEDAI) among MTX-treated patients when compared with controls (p = 0.001, odds ratio (OR) 0.444, 95% confidence interval (CI) 0.279 to 0.707). There was also significant reduction in the average dose of corticosteroids among MTX-treated patients when compared with controls (p = 0.001, OR 0.335, 95% CI 0.202 to 0.558). The effect of MTX on laboratory and serological markers, including erythrocyte sedimentation rate, anti-dsDNA and complement levels (C3 and C4), could not be determined because of the limited numbers of controlled trials.
CONCLUSION: The use of MTX is associated with significant reductions in SLEDAI and the average dose of corticosteroids in adult patients with SLE.

Effective antiretroviral drugs have been developed that, if continuously administered (although with simplification strategies once a patient's viral titer is suppressed) allow for a functional cure resulting in an almost normal life despite the presence of viral reservoirs. In that sense, observations that combination antiretroviral therapy has an untoward suppressive effect on antibody-dependent cellular cytotoxicity against T cells permitting the establishment of such viral reservoirs were discussed for its implications in the use of vaccines and/or modulators of the immune function to clear latent infections and the risk for reactivation (Madhavi, V. et al., Abst MOLBPE05). In addition to latent viral reservoirs, individual patient characteristics may also influence response to antiretroviral therapy, as exemplified by the increased likelihood of highly active antiretroviral therapy in patients carrying certain polymorphic variants (rs2229109, rs6961419) of the P-glycoprotein 1 gene (Dias, J. et al., Abst MOPE034). These, and many other important news derived from research into novel approaches to fight HIV infection were discussed during the International AIDS Society (IAS) meeting in Kuala Lumpur, as summarized in the following report.

Fulltext Glycaemic control and cost analysis when changing from gliclazide co-administered with metformin to pre-combined glibenclamide-metformin tablets in type 2 diabetes mellitus

Lim PC, Lim SL, Oiyammaal C

Med J Malaysia, 2012 Feb;67(1):21-4.
PMID: 22582544

Type-2 diabetes mellitus (T2DM) patients who were on gliclazide co-administered with metformin were changed to pre-combined glibenclamide-metformin tablets in the Endocrine Clinic, Penang Hospital. We conducted a retrospective study to evaluate the differences in glycaemic control and treatment cost following the change. Eighty patients (60% females) with a mean age of 55 years old were studied. Mean glycosylated haemoglobin (HbAlc) reduction was -0.92% (p<0.01) and -0.83% (p<0.01) after three and six months respectively. Patients with baseline HbA1c > or =8% had greater reduction in mean HbA1c (-1.36%) after six months. The treatment cost per month was reduced by 45% at 3 months (p<0.01)) and 44% at 6 months (p<0.01). The change to pre-combined glibenclamide-metformin tablets resulted in significant improvement in glycaemia and reduction in treatment cost.

Adjunctive mood stabilizer treatment for hospitalized schizophrenia patients: Asia psychotropic prescription study (2001-2008)

Sim K, Yong KH, Chan YH, Tor PC, Xiang YT, Wang CY, et al.

Int. J. Neuropsychopharmacol., 2011 Oct;14(9):1157-64.
PMID: 21557883 DOI: 10.1017/S1461145711000563

Recent studies indicate relatively high international rates of adjunctive psychotropic medication, including mood stabilizers, for patients with schizophrenia. Since such treatments are little studied in Asia, we examined the frequency of mood-stabilizer use and its clinical correlates among hospitalized Asian patients diagnosed with schizophrenia in 2001-2008. We evaluated usage rates of mood stabilizers with antipsychotic drugs, and associated factors, for in-patients diagnosed with DSM-IV schizophrenia in 2001, 2004 and 2008 in nine Asian regions: China, Hong Kong, India, Korea, Japan, Malaysia, Taiwan, Thailand, and Singapore. Overall, mood stabilizers were given to 20.4% (n=1377/6761) of hospitalized schizophrenia patients, with increased usage over time. Mood-stabilizer use was significantly and independently associated in multivariate logistic modeling with: aggressive behaviour, disorganized speech, year sampled (2008 vs. earlier), multiple hospitalizations, less negative symptoms, younger age, with regional variation (Japan, Hong Kong, Singapore>Taiwan or China). Co-prescription of adjunctive mood stabilizers with antipsychotics for hospitalized Asian schizophrenia patients increased over the past decade, and was associated with specific clinical characteristics. This practice parallels findings in other countries and illustrates ongoing tension between evidence-based practice vs. individualized, empirical treatment of psychotic disorders.

Polymyositis associated with hepatitis B: management with entacavir and prednisolone

Wong MH, Sockalingam S, Zain A

Int J Rheum Dis, 2011 Aug;14(3):e38-41.
PMID: 21816012 DOI: 10.1111/j.1756-185X.2011.01602.x

We report a 57-year-old woman with a 20-year history of hepatitis B presenting with progressive proximal lower limb weakness for the previous 1 month. Previous medical history included a pericardial and pleural effusion, of which no cause was found and pulmonary tuberculosis which has been adequately treated. Examination revealed multiple telangiactasia over face and nail beds and bilateral proximal lower limb weakness of power 4/5. Biochemical investigation revealed a raised erythrocyte sedimentation rate of 36 mm/h, elevated creatinine kinase levels (14,363 IU/L) and raised liver enzymes (alanine aminotransferase 445 IU/L, aspartate aminotransferase 606 IU/L) with high hepatitis B virus DNA (1,021,158 copies/mL). Nerve conduction tests and muscle biopsy were consistent with polymyositis. She received entacavir for hepatitis B treatment. Despite treatment with entacavir for 10 weeks, her weakness persisted and prednisolone was added. Upon commencement of prednisolone, her symptoms and biochemical profiles returned to normal.

Bilateral simultaneous infectious keratitis secondary to contact lens wear: an unusual case report with rare organisms

Ali NA, Reddy SC

Eye Contact Lens, 2007 Nov;33(6 Pt 1):338-40.
PMID: 17993833

PURPOSE: To report an unusual case of bilateral simultaneous hypopyon corneal ulcer in a contact lens wearer caused by polymicrobial infection with rare organisms.
METHODS: A case report of a 21-year-old soft contact lens wearer, who visited the emergency department with a 3-day history of pain, redness, decreased vision, photophobia, and tearing in both eyes. Examination showed a central corneal ulcer with hypopyon in both eyes. The cultures from corneal scrapings of both eyes, the contact lenses, and the contact lens solution showed heavy growth of Pseudomonas aeruginosa, Alkaligenes species, and Flavobacterium meningosepticum.
RESULTS: The corneal ulcers healed completely with aggressive antibiotic treatment for 4 weeks. The best-corrected visual acuity after 6 months of follow-up was 20/400 in the right eye and 20/60 in the left eye.
CONCLUSIONS: The possibility of infectious keratitis should be kept in mind for an acute red eye in contact lens wearers, and appropriate initial management is essential for a successful outcome. It is believed that this is the first report of Flavobacterium meningosepticum as a causative organism in contact lens-related keratitis.

Fulltext Peginterferon alfa-2b and ribavirin in thalassaemia/chronic hepatitis C virus-co-infected non-responder to standard interferon-based

Hamidah A, Thambidorai CR, Jamal R

Med J Malaysia, 2005 Oct;60(4):517-9.
PMID: 16570722

We describe a patient with HbE-beta thalassaemia and chronic hepatitis C virus infection (genotype 1a) who was treated successfully with peginterferon alfa-2b and ribavirin, following failure to respond to standard interferon and ribavirin therapy. She had sustained virological response for nearly 24 months after completing peginterferon alfa-2b and ribavirin therapy. Transfusion requirements were significantly increased during combination therapy due to ribavirin-induced haemolysis. The adverse effects of interferon were well tolerated. Combination therapy with peginterferon alfa-2b and ribavirin maybe a feasible treatment option for a subset of thalassaemia/HCV infected non-responders to standard interferon-based therapy.

Fulltext Pegylated interferon alfa-2b (peg-intron) plus ribavirin (rebetol) in the treatment of chronic hepatitis C: a local experience

Seow EL, Robert Ding PH

Med J Malaysia, 2005 Dec;60(5):637-41.
PMID: 16515116

This was an open-label, uncontrolled study with the aim of assessing the efficacy and safety of pegylated interferon alfa-2b plus ribavirin in the treatment of chronic hepatitis C. The study was conducted in Island Hospital, Penang beween January 2002 and December 2003. Thirty-three patients were enrolled in this study with ten defaulters. The overall sustained virological response (SVR) (Intention-To-Treat analysis) in naïve patients was 39.10%. However, when the study was adjusted to only include those who completed treatment and follow-up, overall SVR as 52.9%. Side-effects were tolerable in most patients with anaemia occurring in 22 patients (66.7%), leukopenia 23 patients (69.7%) and thrombocytopenia in 15 patients (45.5%). This study showed that pegylated interferon alfa-2b 1.5 mcg/kg/week plus ribavirin > 10.6 mg/kg/day is efficacious and safe to be used in the treatment of: chronic hepatitis C.

Chronic hepatitis B--treatment with nucleoside analogues

Leung N

Med J Malaysia, 2005 Jul;60 Suppl B:22-7.
PMID: 16108169

Nucleot(s)ide analogues are making milestones in the treatment of chronic hepatitis B (CHB) as safe oral therapy. FDA approved lamivudine in adult patients in 1998, adefovir dipivoxil in 2002, and entecavir in March 2005. Lamivudine is effective in viral suppression, ALT normalization, and improvement in histology in both HBeAg positive and HBeAg negative / HBV DNA positive patients. HBeAg seroconversion rates correlate directly with pretreatment ALT levels at 18-30% after one year of therapy. Hepatitis flares may occur if lamivudine is stopped before HBeAg seroconversion. Lamivudine resistant YMDD mutants emerge at a rate of 15-20% per year of therapy; often associated with the rebound viraemia, relapse of hepatitis or even hepatic decompensation. Durability of response off lamivudine therapy is not satisfactory and may be dependent on duration of therapy post-seroconversion. Lamivudine is well tolerated with few serious adverse events, even in patients with decompensated cirrhosis. Long term therapy in viraemic patients with advanced fibrosis or cirrhosis delays clinical progression. Adefovir dipivoxil is an oral prodrug of adefovir. 10 mg daily is effective in suppressing both wild-type HBV and YMDD mutants, normalising ALT and improving histology. Adefovir dipivoxil has been shown to be well tolerated in longterm therapy. Renal toxicity reported in higher dosages is rarely seen except among patients with creatinine clearance less than 50 ml/min. Adefovir resistance may emerge and the overall rate is much lower than lamivudine, reaching 18% after 4 years of therapy. Adefovir-resistant mutants (rt N236T) are susceptible to lamivudine and entecavir. Little data is available for durability of response off therapy. Entecavir is an oral nucleoside analogue with a recommended dosage of 0.5 mg daily for nucleoside-naive patients, and 1 mg daily for lamivudine-refractory patients. It is a potent antiviral and may also reduced intrahepatitic cccDNA. Entecavir resistance so far has only been detected in lamivudine resistant patients in the one-year studies. Patient counseling is very important to decide on the choice among available therapeutic options. The assessment of the risks/benefits of each option should be carefully explained to individual patient.

Fulltext A randomized controlled trial of increased dose and frequency of albendazole with standard dose DEC for treatment of Wuchereria bancrofti microfilaremics in Odisha, India

Kar SK, Dwibedi B, Kerketa AS, Maharana A, Panda SS, Mohanty PC, et al.

PLoS Negl Trop Dis, 2015 Mar;9(3):e0003583.
PMID: 25781977 DOI: 10.1371/journal.pntd.0003583

Although current programmes to eliminate lymphatic filariasis have made significant progress it may be necessary to use different approaches to achieve the global goal, especially where compliance has been poor and 'hot spots' of continued infection exist. In the absence of alternative drugs, the use of higher or more frequent dosing with the existing drugs needs to be explored. We examined the effect of higher and/or more frequent dosing with albendazole with a fixed 300 mg dose of diethylcarbamazine in a Wuchereria bancrofti endemic area in Odisha, India. Following screening, 104 consenting adults were randomly assigned to treatment with the standard regimen annually for 24 months (S1), or annually with increased dose (800 mg albendazole)(H1) or with increased frequency (6 monthly) with either standard (S2) or increased (H2) dose. Pre-treatment microfilaria counts (GM) ranged from 348 to 459 mf/ml. Subjects were followed using microfilaria counts, OG4C3 antigen levels and ultrasound scanning for adult worm nests. Microfilarial counts tended to decrease more rapidly with higher or more frequent dosing at all time points. At 12 months, Mf clearance was marginally greater with the high dose regimens, while by 24 months, there was a trend to higher Mf clearance in the arm with increased frequency and 800 mg of albendazole (76.9%) compared to other arms, (S1:64%, S2:69.2% & H1:73.1%). Although higher and/or more frequent dosing showed a trend towards a greater decline in antigenemia and clearance of "nests", all regimens demonstrated the potential macrofilaricidal effect of the combination. The higher doses of albendazole did not result in a greater number or more severe side effects. The alternative regimens could be useful in the later stages of existing elimination programmes or achieving elimination more rapidly in areas where programmes have yet to start.

Med J Malaysia, 1998 Sep;53(3):223-6.
PMID: 10968157

This paper reports the characteristics and psychopathology of alcohol dependents with alcohol induced psychotic disorder admitted to the Seremban Hospital. The method is that of a case study of all alcohol dependents with alcohol induced psychotic disorder admitted to the Psychiatric Ward, Hospital Seremban over 3 years (1993-1995). There were 34 subjects, 30 Indians, 3 Chinese and 1 Malay with a mean age of 43 years. 32 were men and predominantly of Social Class IV and V (91%). They had a mean duration of drinking of 14.2 years and had a mean weekly consumption of 69.5 units of alcohol. There was a family history of alcohol dependence in (44%). The majority (68%) consumed samsu with beer the second choice. Auditory hallucinations (26) and delusions (16) were common while visual hallucinations (3) and depression (2) were less frequent. Speech disorder occurred in 4 subjects. 2 developed delirium tremens and 1 died. Liver function test was normal in 55%. All except the death from delirium tremens responded to treatment with a combination of anxiolytics, thiamine and antipsychotics and were rapidly discharged. The mean stay was 7 days. However, (68%) did not return for follow up and only 4 were abstinent from alcohol at the time of follow up.

Fulltext Treatment of chronic hepatitis C virus infection with interferon alfa and ribavirin: sustained response in two patients with transfusion dependent thalassaemia

Hamidah A, Yong JF, Zulkifli HI, Jamal R

Med J Malaysia, 2002 Sep;57(3):353-6.
PMID: 12440276

We describe two cases of transfusion dependent thalassaemics with chronic hepatitis C virus infection whom were treated successfully with interferon and ribavirin, following failure of response or relapse after an initial response to interferon monotherapy. They had sustained virological response for more than twelve months after completing therapy. Transfusion requirements were significantly increased during the combination therapy, probably due to ribavirin-induced haemolysis. Serum ferritin level decreased significantly during the treatment. Combination therapy with interferon alfa and ribavirin may be a feasible treatment option for some nonresponders to prior interferon monotherapy.
