Schizophrenia following new-onset refractory status epilepticus secondary to antiphospholipid syndrome

New-onset refractory status epilepticus (NORSE) is a drug-resistant status epilepticus that often has a catastrophic outcome. Our patient was diagnosed with NORSE and had an EEG reading that showed status epilepticus persisting for 8 months in general anesthesia. After autoimmune workup showed positive antiphospholipid antibodies, his seizure was controlled, and he was discharged with good condition apart from moderate cognitive impairment. However, he later developed schizophrenia. Although psychiatric disorders have been associated with antiphospholipid syndrome, to the best of our knowledge, it has not been reported to be associated with status epilepticus. We recommend vigilance of psychological complications of refractory status epilepticus’ patients for early psychiatric referral, diagnosis, and treatment.

New-onset refractory status epilepticus (NORSE) is a syndrome of new-onset drug-resistant status epilepticus that often has a catastrophic outcome. Epilepsy is usually associated with psychiatric disorders of different manifestations of which psychosis is an example.1 However, not much is found in the literature review regarding psychiatric disorders following NORSE although a recent study concluded 32% of NORSE patients ended up with altered behavioral states like aggression.2 Schizophrenia following NORSE like in the rare presentation of this case has not been reported in the literature review before, although an association between schizophrenia and autoimmune disorders like APS has been reported.3     

Buprenorphine pharmacokinetic parameters during coronary artery bypass graft surgery

The pharmacokinetic parameters of buprenorphine (BN) after a single bolus dose of 10 microg/kg i.v. was investigated in 6 male patients whose age averaged 59+/-9.8 years and body weight of 65.8+/-5.7 kg undergoing coronary artery bypass graft surgery (CABG). The unbound BN plasma concentrations were detected using ultrafiltration and high performance liquid chromatography/electro-chemical detection (HPLC/ECD) method. During cardiopulmonary bypass (CPB) there was a fall in BN plasma concentrations, observations similar to reports on fentanyl, sufentanil and alfentanil. This is probably due to haemodilution, hypothermia and hydrophobic sequestration of drug on to the CPB tubing. After CPB the concentrations rose to values higher than during CPB, though it did not attain pre CPB concentrations. These variations were not statistically significant indicating that plasma levels were adequately stable during CPB. The plasma concentration time curves were biexponential and the pharmacokinetic parameters obtained were : distribution half-life 37.24+/-6.57 min, elimination half-life 482.69+/-79 min, clearance 1221.97+/-209.42 ml/min, and volume of distribution 736.46+/-71.25 L. BN in the dose used follows the pharmacokinetic pattern of other commonly used narcotics during CABG. The mean +/- SEM plasma BN concentration during CPB was 0.51+/-0.03 ng/ml which was adequate for the maintenance of analgesia and anaesthesia, as none of our patients expressed the signs and symptoms of awareness during surgery. Further, unlike the other narcotics muscle rigidity was absent. Thus BN is a safe and good alternative to other narcotics for patients undergoing CABG.     

Frequency of serological markers of rheumatoid arthritis in patients with IgA anti‐β2 glycoprotein I antibodies

AimTo determine the frequency of serological markers of RA in patients with anti‐β2 glycoprotein I antibodies (aβ2GPI) of IgA isotype.Material and MethodsA retrospective study was conducted on 67 patients with aβ2GPI‐IgA. Ninety healthy blood donors (HBD) were used as a control group. IgG anti‐cyclic citrullinated peptides antibodies (CCP‐Ab) and rheumatoid factors (RF) IgG, IgA, and IgM were detected by enzyme‐linked immunosorbent assay (ELISA).ResultsSeventeen patients and eight HBD had CCP‐Ab and/or RF (25.4% vs. 8.9%, p = 0.005, CI 95% [14.95; 35.79], odds ratio = 3.5). The frequency of CCP‐Ab was significantly higher in patients than in healthy subjects (14.9% vs. 3.3%, p = 0.009). IgA isotype of RF was significantly higher in patients than in controls (7.5% vs. 0%, p = 0.02). In male patients, CCP‐Ab and/or RF were more frequent than in healthy male subjects (37.5% vs. 11.8%, p = 0.02). In patients, no correlation was found between the levels of aβ2GPI‐IgA and CCP‐Ab (r = 0.082, p = 0.51). There was no correlation between the level aβ2GPI‐IgA and the level of the isotypes of RF (IgG, IgA, and IgM) in patients (r = 0.1, p = 0.37; r = 0.17, p = 0.17 and r = 0.07, p = 0.59 respectively).ConclusionFrequencies of CCP‐Ab and RF are high in patients with aβ2GPI‐IgA suggesting that these patients are susceptible to developing RA.     

Epidemiological, clinical and laboratory findings of infectious keratitis at Mansoura Ophthalmic Center, Egypt

AIM: To analyze the epidemiological, clinical and laboratory findings of infectious keratitis. METHODS: A retrospective study on cases of infective keratitis, attended our institution from Mar. 2013 to Feb. 2015, was done at Mansoura Ophthalmic Center, Egypt. Corneal scrapings were performed and processed for direct microscopy and culture in appropriate media using standard laboratory protocols. RESULTS: Out of 245 patients enrolled for study, 247 corneal scrapings were obtained. Ocular trauma was the most common predisposing factor (51.4%), followed by diabetes mellitus (15.1%). Cultures were positive in 110 scraping samples (44.5%): 45.5% samples had pure fungal infection, 40% had pure bacterial infections and 10% had mixed fungal and bacterial growths. Acanthamoeba was detected in 5 (4.5%) samples. The most common fungal pathogen was Aspergillus spp. (41%). The most common bacterial isolates were Staphylococcus aureus (38.2%) and Pseudomonas aeruginosa (21.8%). CONCLUSION: Incidence of fungal keratitis is high in our region. Therapeutic approach can initially be based on clinical features and sensitivity/resistance patterns. Microbiological research should direct the antimicrobial treatment. Antibiotic resistance to fluoroquinolones and aminoglycosides is an important consideration.     

Adopting global tools for the advancement of pharmacy practice and workforce in Saudi Arabia

BackgroundThe continuing expansion of the pharmacist’s role necessitates continuous evaluation of current practice to identify strategies for improvements. The International Pharmaceutical Federation (FIP) has developed tools to support stakeholders in identifying development needs and planning advancement strategies. The aim of this research was to utilise the FIP Global Competency Framework, version 2 (GbCF v2), and FIP Development Goals (DGs) to evaluate competencies related to pharmacy practice in Saudi Arabia, and to understand the strategies needed to develop and improve the current practice.MethodsThe study involved four phases. Phase 1 involved translation of the FIP GbCF v2 into the Arabic language. Phase 2 was a consensus panel validation to establish the initial relevance of the competencies to current practice. Phase 3 included a national survey distributed to all registered pharmacists in Saudi Arabia. The final phase was conducted through mapping ‘not relevant’ competencies to FIP DGs to identify priorities.ResultsThe translation phase yielded a bilingual framework that could be utilized by pharmacists in Saudi Arabia. The initial validation phase identified 61 behavioral statements (from 124 in the GbCF v2) as ‘highly relevant’ or ‘relevant’ to pharmacy practice. Findings from the national survey identified a list of ‘not relevant’ competencies that could highlight gaps in current practice. The final mapping phase generated a list of three FIP DG priorities: DG5 (competency development), DG8 (working with others) and DG11 (impact and outcomes).ConclusionThe study indicated that competencies in the GbCF v2 were relevant to pharmacists practicing in the country. However, some competencies were perceived as ‘not relevant’ to current practice and these highlighted gaps in the current practice that need attention. Mapping ‘not relevant’ competencies to FIP DGs should be used as a starting point towards developing strategies, systems, and protocols to advance pharmacy practice in Saudi Arabia.     

The utilization of Arabic online drug information among adults in Saudi Arabia

In Saudi Arabia, the utilization of the world wide web has become increasingly popular. However, the exact figure of such use is unknown. This study aimed to determine the percentage of, and experience with, online Arabic drug information by Arabic-speaking adults in Saudi Arabia. A web based questionnaire was used. The questionnaire language was Arabic. Public were invited to participate in the survey through e-mails, Twitter, WhatsApp and Facebook in March 2012. The survey included 17 items examining the types of accessed Arabic drug information, the respondent’s demographics, their ability to easily find and understand Arabic drug-related information, and their trustfulness and dependency on such information websites. Of the 422 Arabic speaking adults who answered the questionnaire, 88% stated that they used Arabic websites to answer drug-related questions. Of the respondents, 50% had a bachelor’s degree, 44% were young adults, over half were female (60%), and 72% of them have a chronic disease. The ease of retrieving online information was the most common reason (69%) for consulting such websites. Google as a search engine was the most frequently (86%) accessible website. Although respondents reported different drug-related topics in their online searching, the search for adverse effects was the most common (68%). Respondents claimed that they could easily find (65%) and understand (49%) the drug-related information. Although a good number of respondents qualified this type of information as good, double-checking of information on other websites was highly recommended. Trustfulness was one of the important parameters to measure and 205 respondents (55%) claimed that they only trusted half of the information cited. Moreover, around 48% of respondents considered that finding the same information on more than one website increased its trustfulness. Surprisingly, 54% of respondents did not depend on Arabic information websites when making decisions on drug use. There are a high proportion of Arabic speaking people in Saudi Arabia using and consulting Arabic drug information websites. This information is easily found and understood. However, the quality and trustfulness of such websites are not high enough to depend on them. A qualified Arabic drug information website is important to meet this need.     

Potential of two nucleic acid amplification assays for quantifying mycobacterial load in respiratory and non-respiratory specimens: a prospective study

Quantification of bacillary load plays a critical prognostic role in tuberculosis patients. This study evaluated the potential of the Cepheid GeneXpert (GX) MTB/RIF and the BD ProbeTec system as quantitative assays. The time to positivity (TTP) measured by the Mycobacterial Growth Index Tube system was compared to the cycle threshold (C_t) of GX MTB/RIF and the Metric Other than Acceleration (MOTA) scores generated by the ProbeTec system. Out of 714 samples examined, 44 culture confirmed cases were identified. The C_t values in 21 respiratory samples showed a high linear fit with the TTP in liquid culture (Spearman's correlation coefficient r = 0.9, P value < 0.0001), which was not the case in 23 non-respiratory samples. In both types of specimens, the MOTA scores did not correlate with the TTP in liquid culture. This indicates the suitability of GX as a quantitative measurement of mycobacterial load in respiratory but not non-respiratory specimens.     

Screening for celiac disease,by endomysial antibodies,in patients with unexplained articular manifestations

Celiac disease (CD) is an autoimmune systemic disease characterized by not only gastrointestinal but also extraintestinal manifestations. The aim of our study was to do a serological screening for CD, by IgA endomysial antibodies (EmA), in patients with unexplained articular manifestations. Two hundred and eleven patients suffering from arthritis or arthralgia without evident cause were studied. EmA were determined by indirect immunofluorescence on human umbilical cord. Two thousand and five hundred blood donors served as control group. Out of 211 patients, 5 had EmA (2.37 %). The frequency of EmA in our patients was significantly higher than in the control group (2.37 vs. 0.28 %, p < 0.01). All patients with positive EmA were female. EmA were significantly more frequent in female patients than in female healthy subjects (3 vs. 0.4 %, p < 0.01). Medical records revealed: diarrhea (one patient), short size (one patient), anemia (three patients), weight loss (two patients) spontaneous abortion (three patients), secondary amenorrhea (one patient), early menopause (one patient) and early baby death (one patient). Biochemical analysis showed decreased level of calcium (one patient), vitamin D (one patient) and cholesterol (one patient). Unexplained liver cytolysis was observed in two patients. Radiological examination showed demineralization of two hands in one patient. Bone osteodensitometry done in one patient out of five revealed lumbar osteopenia. The articular manifestations of the five patients did not respond to corticosteroid treatment. CD must be considered among the differential diagnosis in a patient with arthritis or arthralgia.     

First experience of the use of a generic of plerixafor in peripheral blood stem cell mobilization in multiple myeloma and lymphoma patients

Mobilization failure in patients is a major therapeutic concern which makes subsequent ASCT impossible. A new growth factor called Plerixafor (Mozobil®) developed by the pharmaceutical industry (Sanofi-aventis, France), is a chemoreceptor antagonist, CXCR4 type, which disrupts the interaction of SDFI and CXCR4, thereby enhancing the effect of G-CSF mobilization and is especially indicated for mobilization failure. Currently, there is a generic of plerixafor developed by the pharmaceutical industry (Hetero Drugs Ltd, India). The brand name of this medicine is Mozifor®. The objective of this study was to evaluate if generic plerixafor has the same efficacy and safety as originator plerixafor when used with G-CSF in the mobilization of PBSCs for autologous ASCT in multiple myeloma (MM) and lymphoma failure patients. The 32 patients received plerixafor were divided in two groups. The first group concerns the 11 consecutive patients prospectively received generic plerixafor (Mozifor®) in the period between January to July 2020. These were compared with a retrospective control cohort (second group n = 21) who had been treated between 2009 and 2019 with originator plerixafor (Mozobil®). For the Mozifor® group, the mean CD34+ was 4.54x10⁶/kg(1.56-6.79), the median time to achieve an absolute neutrophil count >0.5 G/L was 13 days (range: 8–21). The median time to self-sustained platelet count >20 G/L was 15 days (range: 8–24). For the Mozobil® group, the mean CD34+ was 3.1x10⁶/kg (0.56-8.91) (p=0.86), the median time to achieve an absolute neutrophil count >0.5 G/L was 10 days (range 7–23). The median time to self-sustained platelet count >20 G/L was 13 days (range: 7–29). Our study showed that the generic of plerixafor was practically identical to that of the originator (Mozobil®) with no significant difference (p = 0.52). This study demonstrates the safety and feasibility of mobilization PBSC with generic plerixafor in ASCT in MM and lymphoma. Although these outcomes are encouraging, prospective comparison with other traditional auto-HCT regimens used for patients with MM and lymphoma is warranted.
