Pre-Ramadan health seeking behavior, fasting trends, eating pattern and sleep cycle in pregnant women at a tertiary care institution of Pakistan.

OBJECTIVE: To observe the pre-Ramadan health seeking behavior, fasting trends, eating pattern and, sleep cycle in pregnant women. METHODS: It is a cross-sectional observational study, from July to September 2017, conducted at Tertiary Care Hospital in Karachi. The tool used for data collection was interviewer based closed ended questionnaire, 279 pregnant women who fasted during Ramadan were included in the study. RESULTS: One to ten days of fasting was observed by 85.7% (198) of women. About 72.4% (202) never consulted any doctor for pre-Ramadan advice regarding fasting in pregnancy. Pregnant women 81.7% (228) believed that fasting would not cause any harm to their unborn child, while 42.7% (119) of family members feared about the health of mother and unborn child. Seventy four percent (208) of respondents had a reduced sleep cycle of about 3-4 hours. The food items consumed at Sehri and Iftar were rich in carbohydrates and fats. CONCLUSIONS: Pre-Ramadan medical consultation regarding safety of fasting during pregnancy should be structured and customized for women and their families. Gaps in knowledge identified in this study may help healthcare professionals to address these issues.

Recommendations for management of diabetes and its complications during Hajj (Muslim pilgrimage).

Hajj is one of the five pillars of Islam and is a must-do for all adult Muslims once in their life provided they are able to do it. Considering the 8.8% global prevalence of diabetes, coupled with the number of Muslims performing Hajj (~2.5 million adult Muslims), it could be estimated that Muslims with diabetes performing Hajj may exceed 220 000 per year. According to Islamic rules, Hajj should not cause severe difficulties for Muslims. The Holy Qur'an specifically exempts from this duty Muslims who are unable physically or financially if it might lead to harmful consequences for the individual. This should be applicable to subjects with diabetes considering its severe and chronic complications. During the Hajj, diet, amount of fluid intake and physical activity may be altered significantly. This exemption from the duty is usually not considered a simple permission; Muhammad the Prophet of Islam mentioned, 'God likes his permission to be fulfilled, as he likes his will to be executed'. However, most Muslims with diabetes prefer to do the Hajj duty, and this may cause major medical challenges for Muslims with diabetes and their healthcare providers. So it is very important that healthcare providers are aware of the possible risks that could happen during the Hajj. People with diabetes may face many health hazards during the Hajj, including but not limited to the 'killer triad': hypoglycemia, foot injury and infections. Many precautions are necessary in the prevention and treatment of possible serious complications. Risk stratification, medication adjustments, proper clinical assessment, and education before doing the Hajj are crucial.

Maternal Nutrition during Early Pregnancy and Cardiometabolic Status of Neonates at Birth.

OBJECTIVE: To explore the impact of maternal body weight on maternal nutrition and micronutrient status in early pregnancy and potential impact on metabolic status in newborns. METHODOLOGY: The EU FP7 project GIFTS was conducted from Jan 2012 to May 2014. Demographic details and anthropometric measurements of women in the first trimester of pregnancy were obtained. Blood samples were collected for OGTT, insulin, lipid profile, serum folate, ferritin, vitamin D, vitamin B12, and red cell folate. Newborn anthropometric characteristics were observed. Cord blood samples were collected after delivery for glucose, insulin, and lipid profile of newborns. RESULTS: A total of 301 pregnant mothers, 108 overweight, 63 underweight, and 130 normal weight were included. Prevalence of vitamin D deficiency (<30 ng/mL) and low vitamin B12 (<190 ng/l) were high, 44% and 42%, respectively, in the first trimester. Anemic women (due to B12 or iron deficiency) were 79%, while 72% had low ferritin levels. Gestational diabetes was 16%. Differences were observed between underweight and overweight mothers (P < 0.05) for fasting blood glucose, insulin levels, and serum ferritin were observed. No significant difference was observed between vitamin D, serum B12, and red cell folate levels. CONCLUSION: Prevalence of multiple micronutrient deficiencies was common among Pakistani women during early pregnancy despite the nonvegetarian diet that has important implications for pregnancy care in Pakistan and potentially in expatriate communities living abroad. This trial is registered with ISRCTN number 83599025.

Pakistan's Recommendations for Optimal Management of diabetes from Primary to Tertiary care level (PROMPT).

Pakistan is a developing country with limited resources and diverse socio-economic standards. Pakistan has high prevalence of diabetes and its complications, which is a great challenge to the existing health care system. National action plans for control of diabetes have been developed and initiatives have been taken but not at an ideal pace. First National Practice Guidelines for Pakistan were published in 1999. It was very helpful in standardizing the management of Type-2 diabetes. In view of important developments in the field of diabetes during the recent years, it was felt that 1999 National Clinical Practice Guidelines edited, should be revised. Also with rapidly increasing number of diabetic patients and the escalating burden on health economy, it is essential to develop a primary to secondary / tertiary care referral system. These guidelines are developed after an extensive research and cover many aspects of diabetes management. This special communication is an extract of a PROMPT document that has already been published as a Supplement in Pakistan Journal of Medical Sciences in 2017. We hope that these guidelines will help in improving the diabetes care in Pakistan.

Effect of angiotensin converting enzyme inhibitor on glomerular hyperfiltration in patients with type 1 diabetes.

OBJECTIVE: To assess the effect of angiotensin converting enzyme inhibition on glomerular filtration rate (GFR) in normotensive patient with type 1 diabetes. METHODS: A two year non-placebo control prospective study was conducted after ethical approval at Diabetes Centre of Diabetic Association of Pakistan, a WHO collaborating centre in Karachi, Pakistan. All patients with type 1 diabetes visited the out-patients department from August 2009 till July 2011 and those who fulfilled the inclusion criteria were invited to participate. A total of 121 people aged ≥18 years and ≥ 5 years of diabetes were included. Pregnant and lactating woman and those aged <18 years were excluded. GFR was calculated by using CKD-EPI formula (eGFR) at baseline and after two year. On the basis of estimated GFR, patients at baseline were divided according to KDIGO classification of chronic kidney diseases into, hyperfiltration (eGFR ≥ 100 ml/min) and normal filtration group (eGFR < 100 ml/min). All subjects in hyperfiltration group received ACE inhibitor (treatment group) while patients with normal filtration did not receive ACE inhibitor (control group). RESULTS: Fifty two patients (43%) were in the treatment and sixty nine (57%) were in the control group. At baseline eGFR, systolic and diastolic blood pressures between groups were non-significantly different. After two years, compared to baseline, eGFR of the treatment group declined and the control group increased significantly. No significant difference in systolic while diastolic blood pressure of the treatment group increased significantly after two years compared to baseline. In contrast both systolic and diastolic blood pressure of control group increased significantly after two years compared to their baseline values. CONCLUSION: Present study demonstrated that initiation of ACEI in hyperfiltration stage declined GFR and keep blood pressure within normal range.

Comparison of Ramadan-specific education level in patients with diabetes seen at a Primary and a Tertiary care center of Karachi-Pakistan.

AIMS: To compare Ramadan-specific education level in fasting patients with diabetes at a Primary and a Tertiary care center. METHODOLOGY: An observational study was conducted in the Outpatient departments of a Primary care center and a Tertiary care center in Karachi-Pakistan. Recruitment of patients started at the end of Ramadan 2011 and continued till three months after Ramadan 2011. All patients with diabetes who observed fast during the month of Ramadan 2011 were included in the study. In Primary care center, patients were attended by physicians only, while at Tertiary care center patients were seen by physicians, diabetes educator and dietician. For data collection, standardized questionnaire based interview was conducted on one to one basis by trained healthcare professionals. Same questionnaire was used at both the centers. RESULTS: A total of 392 and 199 patients with diabetes recruited at Primary and Tertiary care centers, respectively. Ramadan-specific diabetes education received by 213 (55%) and 123 (61.80%) patients with diabetes at Primary and Tertiary care centers, respectively. Compared to Primary care center, patients at Tertiary care centers were more aware about components of Ramadan-specific diabetes education such as signs and symptoms of hypoglycemia and hyperglycemia, dose of medicines/insulin during Ramadan fasting, dose of medicines/insulin when not fasting, self-monitoring of blood glucose, dietary modifications, physical activity, adequate nutrition and adequate hydration during Ramadan (p<0.05). CONCLUSION: It was observed that Ramadan-specific education level of patients at Tertiary care center was significantly better compared to patients at Primary care center.

Frequency, severity and risk indicators of retinopathy in patients with diabetes screened by fundus photographs: a study from primary health care.

OBJECTIVE: To determine the frequency, severity and risk indicators of diabetic retinopathy (DR) in patients with diabetes attending a primary care diabetes centre. METHODS: This observational study was conducted at Diabetic Association of Pakistan - a World Health Organization collaborating center in Karachi, from March 2009 to December 2011. Registered patients with diabetes were screened by two field fundus photographs. Retina specialists graded the signs of retinopathy according to diabetic retinopathy disease severity scale. RESULTS: Of total registered diabetic patients (n=11,158), 10,768 (96.5 %) were screened for DR. Overall DR was found in 2661 (24.7%) patients. DR was found in decreasing order of frequency in patients with type 2 (n= 2555, 23.7%) followed by patients with type 1 diabetes (n=101, 0.93% ) and patients with gestational diabetes mellitus (GDM) (n=5, 0.46%). Among patients with DR, signs of non-sight threatening retinopathy was dominant. Females and patients of working age group predominantly had retinopathy. Type 1 patients >16 years and type 2 patients < 5 years of history of diabetes had sign of retinopathy in increased frequency. CONCLUSION: Every forth patient with diabetes in this large cohort had signs of diabetic retinopathy. Females and patients in working age group predominantly had retinopathy. Type 2 patients with short while type 1 patients with long history of diabetes most frequently had DR. Dissemination of the present study findings may help in increasing the awareness of this serious complication of diabetes.

Effect of intervention in subjects with high risk of diabetes mellitus in pakistan.

Aims. To observe the rate of conversion from impaired glucose tolerance (IGT) to diabetes following lifestyle modification (LSM) or a combination of lifestyle and metformin compared to a control population with 18-month followup. Methods. Forty screening camps were organized, which 5000 people attended. Around 2300 persons filled the questionnaire and 1825 subjects were identified as high risk. Of 1739 subjects who took the oral glucose tolerance test, 317 subjects were identified as IGT. The 317 IGT subjects were randomized into three groups: control group was given standard medical advice, LSM group was given intensive lifestyle modification advice, while LSM + drug group was given intensive lifestyle advice and metformin 500 mg twice daily. Results. At the end, 273 subjects completed the study, giving a compliance rate of 86%. Total of 47 incident cases of diabetes were diagnosed (overall incidence was 4 cases per 1000 person-months with the incidence of 8.6 cases in control group, 2.5 cases in the LSM, and 2.3 cases in the LSM + drug groups). Conclusions. Study showed that lifestyle intervention had a major impact in preventing diabetes among IGT subjects in this region. Adding drug did not show any improved results. We recommend lifestyle advice and followup should be incorporated in primary health care.

Circadian gene variants and susceptibility to type 2 diabetes: a pilot study.

BACKGROUND: Disruption of endogenous circadian rhythms has been shown to increase the risk of developing type 2 diabetes, suggesting that circadian genes might play a role in determining disease susceptibility. We present the results of a pilot study investigating the association between type 2 diabetes and selected single nucleotide polymorphisms (SNPs) in/near nine circadian genes. The variants were chosen based on their previously reported association with prostate cancer, a disease that has been suggested to have a genetic link with type 2 diabetes through a number of shared inherited risk determinants. METHODOLOGY/PRINCIPAL FINDINGS: The pilot study was performed using two genetically homogeneous Punjabi cohorts, one resident in the United Kingdom and one indigenous to Pakistan. Subjects with (N = 1732) and without (N = 1780) type 2 diabetes were genotyped for thirteen circadian variants using a competitive allele-specific polymerase chain reaction method. Associations between the SNPs and type 2 diabetes were investigated using logistic regression. The results were also combined with in silico data from other South Asian datasets (SAT2D consortium) and white European cohorts (DIAGRAM+) using meta-analysis. The rs7602358G allele near PER2 was negatively associated with type 2 diabetes in our Punjabi cohorts (combined odds ratio [OR] = 0.75 [0.66-0.86], p = 3.18 × 10(-5)), while the BMAL1 rs11022775T allele was associated with an increased risk of the disease (combined OR = 1.22 [1.07-1.39], p = 0.003). Neither of these associations was replicated in the SAT2D or DIAGRAM+ datasets, however. Meta-analysis of all the cohorts identified disease associations with two variants, rs2292912 in CRY2 and rs12315175 near CRY1, although statistical significance was nominal (combined OR = 1.05 [1.01-1.08], p = 0.008 and OR = 0.95 [0.91-0.99], p = 0.015 respectively). CONCLUSIONS/SIGNIFICANCE: None of the selected circadian gene variants was associated with type 2 diabetes with study-wide significance after meta-analysis. The nominal association observed with the CRY2 SNP, however, complements previous findings and confirms a role for this locus in disease susceptibility.

Effects of 16 genetic variants on fasting glucose and type 2 diabetes in South Asians: ADCY5 and GLIS3 variants may predispose to type 2 diabetes.

BACKGROUND: The Meta-Analysis of Glucose and Insulin related traits Consortium (MAGIC) recently identified 16 loci robustly associated with fasting glucose, some of which were also associated with type 2 diabetes. The purpose of our study was to explore the role of these variants in South Asian populations of Punjabi ancestry, originating predominantly from the District of Mirpur, Pakistan. METHODOLOGY/PRINCIPAL FINDINGS: Sixteen single nucleotide polymorphisms (SNPs) were genotyped in 1678 subjects with type 2 diabetes and 1584 normoglycaemic controls from two Punjabi populations; one resident in the UK and one indigenous to the District of Mirpur. In the normoglycaemic controls investigated for fasting glucose associations, 12 of 16 SNPs displayed ß values with the same direction of effect as that seen in European studies, although only the SLC30A8 rs11558471 SNP was nominally associated with fasting glucose (ß = 0.063 [95% CI: 0.013, 0.113] p = 0.015). Of interest, the MTNR1B rs10830963 SNP displayed a negative ß value for fasting glucose in our study; this effect size was significantly lower than that seen in Europeans (p = 1.29×10(-4)). In addition to previously reported type 2 diabetes risk variants in TCF7L2 and SLC30A8, SNPs in ADCY5 (rs11708067) and GLIS3 (rs7034200) displayed evidence for association with type 2 diabetes, with odds ratios of 1.23 (95% CI: 1.09, 1.39; p = 9.1×10(-4)) and 1.16 (95% CI: 1.05, 1.29; p = 3.49×10(-3)) respectively. CONCLUSIONS/SIGNIFICANCE: Although only the SLC30A8 rs11558471 SNP was nominally associated with fasting glucose in our study, the finding that 12 out of 16 SNPs displayed a direction of effect consistent with European studies suggests that a number of these variants may contribute to fasting glucose variation in individuals of South Asian ancestry. We also provide evidence for the first time in South Asians that alleles of SNPs in GLIS3 and ADCY5 may confer risk of type 2 diabetes.

Genome-wide association study in individuals of South Asian ancestry identifies six new type 2 diabetes susceptibility loci.

We carried out a genome-wide association study of type-2 diabetes (T2D) in individuals of South Asian ancestry. Our discovery set included 5,561 individuals with T2D (cases) and 14,458 controls drawn from studies in London, Pakistan and Singapore. We identified 20 independent SNPs associated with T2D at P < 10(-4) for testing in a replication sample of 13,170 cases and 25,398 controls, also all of South Asian ancestry. In the combined analysis, we identified common genetic variants at six loci (GRB14, ST6GAL1, VPS26A, HMG20A, AP3S2 and HNF4A) newly associated with T2D (P = 4.1 × 10(-8) to P = 1.9 × 10(-11)). SNPs at GRB14 were also associated with insulin sensitivity (P = 5.0 × 10(-4)), and SNPs at ST6GAL1 and HNF4A were also associated with pancreatic beta-cell function (P = 0.02 and P = 0.001, respectively). Our findings provide additional insight into mechanisms underlying T2D and show the potential for new discovery from genetic association studies in South Asians, a population with increased susceptibility to T2D.

Is there any association of serum high-sensitivity C-reactive protein with various risk factors for metabolic syndrome in a healthy adult population of karachi, pakistan?

BACKGROUND: The aim of this study was to discover the association of serum high-sensitivity C-reactive protein (hsCRP) with various risk factors for metabolic syndrome in an urban population of Karachi, Pakistan. METHOD: In this cross-sectional study, 337 healthy adults (108 males and 229 females, mean age 40.7 ± 14.2 years) participated. The subjects were randomly selected in Lyari Town in Karachi using a geographical imaging system (GIS). Their demographic, anthropometric [body mass index (BMI), hip and waist circumferences, waist-to-hip circumference ratio (W-HR), and biochemical (fasting blood glucose, fasting insulin, fasting lipid profile, and hsCRP)] parameters were recorded. Insulin resistance was calculated by the homeostasis model assessment (HOMA-IR). Metabolic syndrome was diagnosed according to the International Diabetes Federation (IDF) criteria. Correlation of CRP and fasting insulin levels with various parameters of metabolic syndrome were calculated using Pearson correlation. RESULTS: Median CRP levels were found to be higher in females 0.81 (0.20-1.38) compared with males 0.77 (0.19-1.35). Metabolic syndrome was diagnosed in 108 (31.12%) subjects. No significant difference between CRP levels in the metabolic syndrome-positive and metabolic syndrome-negative groups was observed. Similarly, no correlation was observed between hsCRP and fasting insulin levels, insulin resistance, and other parameters of MS. CONCLUSION: There is lack of correlation between hsCRP levels and various risk factors for metabolic syndrome in our urban population. Further large-scale prospective studies are needed to confirm these findings.

Pakistan National Diabetes Survey: prevalence of glucose intolerance and associated factors in the Punjab Province of Pakistan.

AIMS: The prevalence of diabetes mellitus and impaired glucose tolerance (IGT) and their relationship to age and obesity were estimated in Punjab, Pakistan by a population-based survey done in 1998. METHODS: Oral glucose tolerance tests were performed in a stratified random sample of 1852 adults aged >or=25 years. The diagnosis of diabetes and IGT were made on the basis of WHO criteria. RESULTS: The prevalence of diabetes was 12.14% in males and 9.83% in females. Overall total glucose intolerance (diabetes and IGT) was present in 16.68% males and 19.37% females. Central obesity, hypertension and positive family history were strongly associated with diabetes. CONCLUSIONS: These results indicate that the prevalence of glucose intolerance is high in the studied population and comparable with the published data from the other three provinces of Pakistan i.e. Sindh, Baluchistan and North West Frontier Province, studied by the same group.

Prevalence of metabolic syndrome in urban Pakistan (Karachi): comparison of newly proposed International Diabetes Federation and modified Adult Treatment Panel III criteria.

The clustering of central obesity, dyslipidemia, hypertension, and hyperglycemia known as metabolic syndrome has been associated with a two- to three-fold increase in type 2 diabetes (T2DM) and cardiovascular disease (CVD). It is recognized that the features of the metabolic syndrome can be present 10 years preceding T2DM and CVD. The objective of our study was to determine the prevalence of metabolic syndrome in adults aged 25 years and older from an urban population of Karachi, Pakistan, according to the International Diabetes Federation (IDF) definition and modified Adult Treatment Panel III (ATP III) criteria. This study involved a survey conducted from July, 2004, to December, 2004, by generating a computerized random sample of households in Lyari Town using a geographical imaging system (GIS). Out of the 85,520 households, 532 households were randomly selected and 867 adults > or =25 years old consented to take part in the survey; 363 of these subjects gave blood samples. The prevalence of diabetes was 9.4%, whereas 5.6% had impaired fasting glucose (abnormal glucose tolerance 15%). The prevalence of metabolic syndrome according to the IDF definition and modified ATP III criteria was 34.8% and 49%, respectively. Inclusion of modified waist circumference and specific body mass index (BMI) cut offs for Asians may help predict metabolic syndrome at an early stage. High prevalence of metabolic syndrome was identified irrespective of the definition applied in this population. This may call for immediate action to halt the accelerating risk of diabetes and CVD that would lead to a possible unparalleled rise in the cost of health care and human suffering.

Prevalence of metabolic syndrome in Pakistan.

Over the past two decades, there has been a striking increase in the number of people with metabolic syndrome. The prevalence of metabolic syndrome varies due to lack of an internationally agreed upon definition. Considering the increased cardiovascular risk among Asian people, a lower cutoff for waist circumference is defined. Obesity in terms of waist circumference is found to be 46-68% of the Pakistani population, with a strong association found between arm fat and insulin insensitivity. In studying dyslipidemia, hypertriglyceridemia is found in 27-54% of the population, whereas 68-81% have low levels of high-density lipoprotein (HDL). Fifty percent were found to be at high risk of metabolic syndrome and as being hypertensive. With the high prevalence of all of these metabolic risk factors, the prevalence of metabolic syndrome in Pakistan according to different definitions is reported to be from 18% to 46%, comparable to the data from other South Asian countries. Thus, metabolic syndrome should be considered as a prime target for preventive medicine. The primary management goals for metabolic syndrome are to reduce the risks of cardiovascular disease and diabetes. Lifestyle-related risk factors are associated with the metabolic syndrome and diabetes. Unless preventive programs are properly designed and implemented, we will continue to treat the majority of the cases after they have already developed the complications. A prospective primary prevention study is underway in Pakistan that will help to create a base for public awareness strategies and nationwide surveillance and prevention programs against noncommunicable diseases.

Determination of reference values for elevated fasting and random insulin levels and their associations with metabolic risk factors among rural Pakistanis from Sindh Province.

AIM: To assess insulin levels and their association with metabolic risk factors (family history of diabetes, abnormal glucose tolerance, hypertension, overweight and android obesity) among a representative group of Pakistan. METHODS: The study data was taken from the database of a population-based survey conducted in Sindh Province, Pakistan, in 1994 to assess the prevalence of diabetes mellitus and impaired glucose tolerance (IGT). Through stratified random sampling; oral glucose tolerance tests were performed in 967 adults; every fifth sample was estimated for fasting and random (2-hour post-75 gm glucose load) insulin levels. The total number of metabolic risk factors was counted for each subject, and their association with insulin levels studied. RESULTS: Of the 130 subjects, 56.1% were females and 95.4% were Sindhi. The mean age of males and females was 43.84 and 40.61 years, respectively. Family history for diabetes and frequency of overweight had significant positive associations with both fasting and random insulin levels (P < 0.05). Association between hypertension and insulin levels was significant only for random insulin levels, and between android obesity, abnormal glucose tolerance, or male gender and insulin levels only for fasting insulin levels (P < 0.05). Metabolic risk factors had significant positive associations with both fasting (r = 0.351 P = 0.000) as well as random insulin levels (r = 0.364 P = 0.000). CONCLUSION: This paper provides baseline pioneering information applicable to the Pakistani population. Furthermore, the observations made in this study about differences in association of fasting or random insulin levels with various metabolic risk factors highlight the possibility of using either of them for risk assessment. This finding needs to be assessed in a larger and nationally representative sample.

Trends of type 1 diabetes in Karachi, Pakistan.

OBJECTIVE: Our study aims to assess the presentation, prevalence, and associations of acute and chronic complications in subjects with type 1 diabetes mellitus (T1DM) at their first visit to outpatient departments. STUDY DESIGN AND SETTING: Study was carried out at two centers, Diabetic Association of Pakistan and WHO Collaborating Centre and Baqai Institute of Diabetology and Endocrinology, Karachi. Records of 591 T1DM subjects divided into two groups were studied. Group 1 (62.1%, n = 367) includes patients with known T1DM and group 2 (n = 224, 37.9%), newly diagnosed T1DM. Clinical features [polyuria, polydipsia, polyphagia, history of weight loss, and history of diabetic ketoacidosis (DKA)] were recorded. Biochemical parameters including fasting plasma glucose, 2-h postprandial plasma glucose, hemoglobin A1c, urinary ketones, and proteinuria were recorded. Arterial blood gases was done in suspected cases of DKA. RESULTS: In group 1, male predominance was seen (57.8 vs. 42.2%). Mean age at presentation was 19.1 +/- 10 yr. Mean duration of diabetes was 16 +/- 9 yr. Two percent subjects presented with DKA, while 21% had a history of DKA. Among the subjects with >10 yr of diabetes, 20.1% had hypertension, 5.5% had nephropathy, 2.9% had neuropathy, and 7.7% had retinopathy. In group 2, 224 T1DM subjects were identified, with mean age of 17 +/- 11 yr. Equal number of males (50.9%) and females (49.1%) were diagnosed at their first presentation. Most subjects (40.8%, n = 91) diagnosed between 11 and 20 yr of age presented with polyuria (81.3%), polydipsia (77.2%), polyphagia (56.7%), and weight loss (79.5%). Ketonuria was positive in 4.9%, while 5.8% presented with DKA. CONCLUSIONS: This is the first study in Pakistan to assess the mode of presentation and prevalence of acute and chronic complications in T1DM. Larger scale prospective studies are needed to have more detailed informative data.

Role of metformin in the initiation of pharmacotherapy for type 2 diabetes: an Asian-Pacific perspective.

Increases in the prevalence of type 2 diabetes of 30-60% will occur in many Asian-Pacific countries by 2025, driven by urbanisation, sedentary habits and energy-rich diets. Obesity, insulin resistance, metabolic syndrome and diabetes are closely interrelated. Optimal control of diabetes and associated risk factors has reduced the risk of diabetes-related complications. In the UK Prospective Diabetes Study (UKPDS), metformin reduced the risk of macrovascular complications and retrospective analyses have confirmed the efficacy of metformin in improving clinical outcomes in type 2 diabetic patients with a history of cardiovascular disease. This growing body of evidence has led to the recommendation of metformin as optimum initial pharmacotherapy in overweight type 2 diabetic patients. Obesity is less prevalent in the Asian-Pacific population than in Caucasian populations. Nevertheless, metformin has multiple beneficial metabolic effects, which provide sufficient rationale for it to be recommended as the initial oral anti-diabetic pharmacotherapy, alone or in combination, irrespective of body mass index. This recommendation is consistent with global guidelines and regional recommendations for the Asian-Pacific region from the International Diabetes Federation. These recommendations can serve as templates for development of local guidelines for Asian people with diabetes, given the ethnic and cultural diversity within the region.
