Efficacy and safety of itopride SR for upper gastrointestinal symptoms in patients with diabetic gastroparesis: real-world evidence from Pakistan.

Background: Gastroparesis is a serious condition that can be caused by diabetes, surgery or infection, or can be idiopathic. When there is no mechanical obstruction, gastroparesis is characterized by delayed stomach emptying. Itopride, a prokinetic drug, inhibits acetylcholinesterase activity in addition to antagonizing dopamine D2 receptors. Methods: This prospective, multicentre study is based on real-world data from 988 patients with a diagnosis of diabetic gastroparesis for index (PAGI-SYM2) evaluation at baseline and week 4 of treatment for upper gastrointestinal disorder symptoms. Results: Upper gastrointestinal symptom severity scores improved significantly after 4 weeks of treatment (p<0.001), with significant improvement across all categories of gastroparesis (very mild (37-58.6%), mild degree (24.6-31.6%), moderate (29.3-7.3%) and severe (8.8-2.6%). Conclusion: Itopride SR (Nogerd SR) in a 150 mg once-daily dose showed promising results in reducing the severity of upper gastrointestinal disorder symptoms associated with diabetic gastroparesis. Both statistical and clinical effectiveness were observed. Moreover, the treatment demonstrated a favourable tolerability profile, with a low incidence of adverse effects.

A Case of Acute Intermittent Porphyria Leading to Severe Disability in a Young 21-Year-Old Female.

Acute intermittent porphyria (AIP) is a rare metabolic disorder that is challenging to diagnose and treat. Symptoms are nonspecific and severe acute attacks may be life-threatening. This is a case of a previously healthy 21-year-old woman diagnosed with an acute attack of AIP following recurrent hospitalizations with undiagnosed abdominal pain over a 12-month period with gradual onset of motor neuropathy which resulted in complete paralysis and respiratory failure. Through our case, we will highlight the challenges in AIP diagnosis and management, its potential severity, and how an early diagnosis could have prevented severe disability.

A cross sectional study to assess nasal carriage of methicillin resistant Staphylococcus aureus in healthcare professionals in a tertiary care hospital.

OBJECTIVE: To determine the nasal carriage of staphylococcus aureus and methicillin-resistant staphylococcus aureus among healthcare workers in a tertiary care setting. METHODS: The cross-sectional study was conducted at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from April to July 2018, and comprised healthcare workers at the institution. Nasal swabs were collected and cultured on Mannitol salt agar. Mannitol fermenting colonies which were gram-positive cocci, catalase-positive and coagulase-positive were identified as staphylococcus aureus. Antibiotic susceptibility test was performed by modified Kirby-Bauer disc diffusion method. Methicillin resistance was detected using cefoxitin disc diffusion method. Data was analysed using SPSS 23. RESULTS: Of the 210 nasal swabs, 52(24.76%) had a staphylococcus aureus growth, and of them, 15(7.1%) were methicillin-resistant. No association could be established with either any single category of healthcare worker or an inter-department variation (p>0.05). Likewise, there was no association with age, gender, duration of service, smoking, co-morbidities, use of antibiotics in the preceding six months, treating a patient with methicillin-resistant staphylococcus aureus in the preceding six months and hospitalisation in the preceding year (p>0.05). CONCLUSIONS: The frequency of nasal carriage of methicillin resistant staphylococcus aureus amongst healthcare workers was regardless of the nature of their professional engagement.

DAR-GRACE: Diabetes and Ramadan: glycaemic control, physician counselling and patient practices -experience from a tertiary care hospital in Pakistan.

OBJECTIVE: To identify patient practices and knowledge pertaining to Ramadan fasting and to see whether physicians were providing adequate counselling and adjusting medications accordingly. METHODS: The cross-sectional study was conducted at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from June to August 2018, and comprised diabetic patients who fasted during Ramadan. A questionnaire was designed to assess patients' knowledge, risk category, pre-Ramadan counselling, medication adjustment, lifestyle changes, pre- and post- Ramadan glycated haemoglobin levels, and complications during Ramadan. Data was analysed using SPSS 23. RESULTS: Out of 272 diabetics, 176(64.7%) were females. Mean number of fasts kept were 22±10.61. Pre-Ramadan 120(44.1%) patients consulted their physicians and 105(87.5%) of them received relevant counselling. Medications were adjusted in only 30 (25%) such cases. Overall, 41(15.1%) patients were in the high risk category, while 109(40.1%) and 122(44.9%) were in the moderate and low-risk categories. During the month, 17(6.25%) were hospitalised due to diabetes-related complications. Glycated haemoglobin levels fell significantly (p<0.0001). CONCLUSIONS: Anomalous patient behaviours and suboptimal physician practices were noticed.

Role of Glucuronidation Pathway in Quetiapine Metabolism: An In vivo Drug-Drug Interaction Study between Quetiapine and Probenecid.

BACKGROUND: Uridine 5'-diphospho-glucuronosyltransferase (UGT) enzymes play a significant role in the metabolism of quetiapine, and coadministration with a UGT inhibitor/inducer drug may change its pharmacokinetic profile. OBJECTIVE: The objective of this study was to assess the impact of probenecid, a UGT enzyme inhibitor, on the pharmacokinetic profile of quetiapine. MATERIALS AND METHODS: Twelve treatment-naïve, 7-week-old male Sprague-Dawley rats (weighting 161 ± 22 g) were randomly and equally divided into control, quetiapine-alone and quetiapine plus probenecid groups. The quetiapine plus probenecid group received a single oral dose of probenecid (50 mg/kg) followed by 50 mg/kg of quetiapine; the quetiapine-alone group only received 50 mg/kg of quetiapine. Blood samples (0.2 ml) were collected from all rats after 0, 0.25, 0.5, 1, 2, 4, 6, 8, 10, 12 and 24 h of the drug administration in heparinized tubes. The pre-established liquid chromatography-mass spectrometry method was utilized to ascertain the plasma concentration of quetiapine and the control group was used to prepare the controlled standard. RESULTS: Significant pharmacokinetic differences were observed between the quetiapine-alone and quetiapine plus probenecid groups in terms of Cmax (392 ± 209 vs. 1323 ± 343 ug/L, respectively, P = 0.004), AUC0-∞ (P = 0.04) and Tmax (P = 0.004). Further, in the combined drug group, there was a decrease in drug clearance (CL/F) (from 27 ± 11 to 16 ± 3 L/h/kg; P = 0.005) and an increase in the volume of distribution (Vd) (P = 0.01), but there was no significant difference between both groups in terms of half-lives (P = 0.27). No significant within-group variability of pharmacokinetic parameters was observed (P = 0.25). CONCLUSION: The results of this animal study suggest that glucuronidation by UGT enzyme system may also play an important role in quetiapine metabolism, which, if proven in future human studies, would imply that the bioavailability and pharmacokinetic parameters of quetiapine may require alterations when co-administered with probenecid to avoid development of quetiapine toxicity.

The ATONE study - assessment of diabetes knowledge in individuals with type 2 diabetes in the Pakistani population.

OBJECTIVE: To evaluate knowledge of diabetes using diabetes knowledge questionnaire in diabetic patients. METHODS: The cross-sectional study was conducted at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from October to December 2017, and comprised subjects aged >20 years with a diagnosis of type 2 diabetes. The modified version of diabetes knowledge questionnaire was used for data collection. It had 24 questions concerning patient's diabetes knowledge and self-care practices. One point was given for each correct answer. The highest achievable score was 24. A total score of ?12 was considered suggestive of adequate knowledge. SPSS 23 was used for data analysis. RESULTS: Of the 401 subjects, 175 (43.6%) were males and 226 (66.4%) were females. The overall mean age was 52.9 }12.3 years, and mean duration of diabetes was 7.95}6.7 years. The mean score on the questionnaire was 9.97}3.93. Only 135(33.7%) patients showed adequate knowledge of the disease. Factors having positive correlation with the score were patient's urban background, level of literacy and their socioeconomic status (p<0.05 each). The duration of diabetes and the control of diabetes had no influence on the scores (p>0.05 each). CONCLUSIONS: Knowledge about diabetes was found to be generally poor among diabetics.

Foot-care behaviour amongst diabetic patients attending a federal care hospital in Pakistan.

OBJECTIVE: To assess foot-care behaviour in diabetics attending a tertiary care hospital, and to see if there are any influencing factors. METHODS: The cross-sectional descriptive study was conducted from September to November 2017 at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, and comprised diabetes patients either admitted to the wards or attending the outpatient clinics. Foot-care behaviour was assessed through the validated Nottingham Assessment of Functional Foot-care scale. A score over 50 demonstrated adequate foot-care behaviour. The score was correlated with several variables. SPSS 23 was used for data analysis. RESULTS: Of the 400 individuals, 238(59.5%) were females and 162(40.5%) were males. The overall mean age was 52.71}11.84 years. Of the total, 228(57%) had never received any education on proper foot-care; 289(72.3%) had a scale score of less than or equal to 50. Urban or rural residence, monthly income, literacy level, family history of diabetes, and previous foot-care education provided by the healthcare provider were significant factors associated with good foot-care behaviour (p<0.05 each). CONCLUSIONS: A majority of the patients demonstrated inadequate foot-care behaviour..
