A retrospective study comparing the results of continuous glucose monitoring to self-blood glucose monitoring for pregnant women with type 1 diabetes mellitus.

BACKGROUND: Type 1 diabetes mellitus (T1DM) is associated with adverse maternal and fetal outcomes. Continuous glucose monitoring (CGM) during pregnancy is associated with better glycemic control in women with T1DM. However, no clear benefits have been demonstrated in reducing adverse feto-maternal outcomes in pregnant women with T1DM. DESIGN AND METHODS: This is a retrospective, single-center study of pregnant women with T1DM to evaluate the impact of CGM use on glycemic control and feto-maternal outcomes in pregnant women with T1DM. RESULTS: Of 265 women with T1DM, 92 (34.7%) used CGM, and 173 (65.3%) were managed with capillary blood glucose (CBG) monitoring. The mean (SD) age and BMI at the first visit were 29.4 (4.7) years and 27.2 (5.2) kg/m2, respectively. The mean (SD) HbA1c at the first-trimester visit was 63 (1) mmol/mol, and in the last trimester was 51 (1%). There was no difference in the mean changes in HbA1c between the two groups. Women using CGM had lower insulin requirements (1.02 + 0.37 vs. 0.87 + 0.04 units/kg, p = 0.01). The two groups had no significant differences in maternal or fetal outcomes. CONCLUSION: CGM use in pregnant T1DM women is not associated with improved fetomaternal outcomes.

Successful medical management of a pituitary macroadenoma with features of resistant acromegaly and hyperprolactinemia using pasireotide.

BACKGROUND: The somatostatin analog, pasireotide, is used for the treatment of acromegaly after the failure of surgery and/or first-line medical treatment. CASE PRESENTATION: A 48-year-old male reported that during a workup for obesity in his home country, hyperprolactinemia was diagnosed and a 3.5 × 3.5 cm pituitary macroadenoma was identified on pituitary MRI. He received cabergoline for 6 months; then he was lost to follow-up. He presented at our Endocrine clinic 2 years later for treatment of obesity (BMI 49.5 kg/m2). Biochemical workup revealed that in addition to hyperprolactinemia (7,237 [normal: 85-323 mIU/L), he had acromegaly, evident by elevated insulin-like growth factor 1 (IGF-1) level (450 [normal: 88-210 µg/L]), and a positive growth hormone suppression test, secondary hypothyroidism, and secondary hypogonadism. Pituitary MRI showed that the adenoma encased parts of the left and right internal carotid arteries and encroached on the optic chiasm. Surgical excision was therefore not feasible. He was treated with cabergoline and later, long-acting release (LAR) octreotide. Prolactin levels were reduced with cabergoline, but IGF-1 levels did not respond to octreotide, and it was discontinued. The patient abandoned radiotherapy after two sessions. He was started on LAR pasireotide 40 mg every 4 weeks and continued on cabergoline 0.5 mg per week. His biochemical response was dramatic, with a near normalization of IGF-1 levels in 3 months. After 6 months from starting pasireotide, we increased cabergoline dose from 0.5 mg/week to 3 mg/week. Three months later, IGF-1 level was normalized. The patient developed type 2 diabetes as a side effect of pasireotide; however, this was well-controlled with medications. CONCLUSIONS: The case suggests that pasireotide can provide marked biochemical improvement in acromegaly after the failure of both cabergoline monotherapy and cabergoline plus octreotide. This further confirms a potentially efficacious treatment regimen in treatment-resistant acromegaly with hyperprolactinemia.

Longitudinal Studies of Wearables in Patients with Diabetes: Key Issues and Solutions.

Glucose monitoring is key to the management of diabetes mellitus to maintain optimal glucose control whilst avoiding hypoglycemia. Non-invasive continuous glucose monitoring techniques have evolved considerably to replace finger prick testing, but still require sensor insertion. Physiological variables, such as heart rate and pulse pressure, change with blood glucose, especially during hypoglycemia, and could be used to predict hypoglycemia. To validate this approach, clinical studies that contemporaneously acquire physiological and continuous glucose variables are required. In this work, we provide insights from a clinical study undertaken to study the relationship between physiological variables obtained from a number of wearables and glucose levels. The clinical study included three screening tests to assess neuropathy and acquired data using wearable devices from 60 participants for four days. We highlight the challenges and provide recommendations to mitigate issues that may impact the validity of data capture to enable a valid interpretation of the outcomes.

Cardiovascular autonomic neuropathy is associated with increased glycemic variability driven by hyperglycemia rather than hypoglycemia in patients with diabetes.

AIM: Cardiac autonomic neuropathy (CAN) has been suggested to be associated with hypoglycemia and impaired hypoglycemia unawareness. We have assessed the relationship between CAN and extensive measures of glucose variability (GV) in patients with type 1 and type 2 diabetes. METHODS: Participants with diabetes underwent continuous glucose monitoring (CGM) to obtain measures of GV and the extent of hyperglycemia and hypoglycemia and cardiovascular autonomic reflex testing. RESULTS: Of the 40 participants (20 T1DM and 20 T2DM) (aged 40.70 ± 13.73 years, diabetes duration 14.43 ± 7.35 years, HbA1c 8.85 ± 1.70%), 23 (57.5%) had CAN. Despite a lower coefficient of variation (CV) (31.26 ± 11.87 vs. 40.33 ± 11.03, P = 0.018), they had a higher CONGA (8.42 ± 2.58 vs. 6.68 ± 1.88, P = 0.024) with a lower median LBGI (1.60 (range: 0.20-3.50) vs. 4.90 (range: 3.20-7.40), P = 0.010) and percentage median time spent in hypoglycemia (4 (range:4-13) vs. 1 (range:0-5), P = 0.008), compared to those without CAN. The percentage GRADEEuglycemia (3.30 ± 2.78 vs. 5.69 ± 3.09, P = 0.017) and GRADEHypoglycemia (0.3 (range: 0 - 3.80) vs. 1.8 (range: 0.9-6.5), P = 0.036) were significantly lower, while the percentage median GRADEHyperglycemia (95.45 (range:93-98) vs. 91.6 (82.8-95.1), P = 0.013) was significantly higher in participants with CAN compared to those without CAN. CONCLUSION: CAN was associated with increased glycemic variability with less time in euglycemia attributed to a greater time in hyperglycemia but not hypoglycemia.

Continuous glucose monitoring reveals a novel association between duration and severity of hypoglycemia, and small nerve fiber injury in patients with diabetes.

Objective: Continuous glucose monitoring (CGM) has revealed that glycemic variability and low time in range are associated with albuminuria and retinopathy. We have investigated the relationship between glucose metrics derived from CGM and a highly sensitive measure of neuropathy using corneal confocal microscopy in participants with type 1 and type 2 diabetes. Methods: A total of 40 participants with diabetes and 28 healthy controls underwent quantification of corneal nerve fiber density (CNFD), corneal nerve branch density (CNBD), corneal nerve fiber length (CNFL) and inferior whorl length (IWL) and those with diabetes underwent CGM for four consecutive days. Results: CNBD was significantly lower in patients with high glycemic variability (GV) compared to low GV (median (range) (25.0 (19.0-37.5) vs 38.6 (29.2-46.9); P = 0.007); in patients who spent >4% compared to <4% time in level 1 hypoglycemia (54-69 mg/dL) (25.0 (22.9-37.5) vs 37.5 (29.2-46.9); P = 0.045) and in patients who spent >1% compared to <1% time in level 2 hypoglycemia (<54 mg/dL) (25.0 (19.8-41.7) vs 35.4 (28.1-44.8); P = 0.04). Duration in level 1 hypoglycemia correlated with CNBD (r = -0.342, P = 0.031). Duration in level 1 (181-250 mg/dL) and level 2 (>250 mg/dL) hyperglycemia did not correlate with CNFD (P > 0.05), CNBD (P > 0.05), CNFL (P > 0.05) or IWL (P > 0.05). Conclusions: Greater GV and duration in hypoglycemia, rather than hyperglycemia, are associated with nerve fiber loss in diabetes.

Qatar Diabetes Mobile Application Trial (QDMAT): an open-label randomised controlled trial to examine the impact of using a mobile application to improve diabetes care in type 2 diabetes mellitus-a study protocol.

BACKGROUND: Mobile health (mHealth) is increasingly advocated for diabetes management. It is unclear if mobile applications are effective in improving glycaemic control, clinical outcomes, quality of life and overall patient satisfaction in patients with type 2 diabetes (T2DM). A new mobile application was specifically built for people with T2DM with the help of the local expertise. The objective of the study was to evaluate the effectiveness of the mobile app. METHODS: The planned study is an ongoing open-label randomised controlled trial in which adults living with T2DM treated with insulin will be randomised 1:1 to the use of this diabetes application versus current standard care. The primary outcome will be the difference in mean HbA1c from baseline to 6 months. Other outcome measures include anthropometric measures, hypoglycaemic events, medication adjustments, number of clinical interactions and missed appointments and patient perceptions of their disease and diabetes self-management. The study will randomise 180 subjects for assessment of the primary outcome. DISCUSSION: We hypothesise that the diabetes-specific mobile application will improve glycaemic control, increase patient empowerment for self-management of diabetes and improve interaction between patients and healthcare providers. If the Qatar Diabetes Mobile Application Trial (QDMAT) demonstrates this, it will inform clinical services for the future self-management of T2DM.

Papillary Thyroid Cancer Affecting Multiple Family Members: A Case Report and Literature Review of Familial Nonmedullary Thyroid Cancer.

Familial nonmedullary thyroid cancer (FNMTC) represents 5-10% of NMTC cases. Many controversies are associated with the FNMTC, namely, the minimum required number of affected family members to define the condition, aggressiveness, prognosis, and treatment and screening recommendations. Moreover, the genetic basis of the FNMTC has not yet been identified. We report a family diagnosed with FNMTC and present a comprehensive literature review of the condition. The index case was a 26-year-old male who was diagnosed with locally advanced papillary thyroid cancer (PTC). Then, his family members became worried and asked for a neck ultrasound. Four of his six siblings, in addition to his father, were diagnosed with PTC. In addition, two of his cousins were diagnosed. The patient underwent total thyroidectomy with bilateral neck dissection, and he received 2 doses of radioactive iodine (100 mCi each). Furthermore, one of his siblings required a second surgery with repeated radioactive iodine therapy. The index case genetic screening and whole-exome sequencing did not show any abnormalities. Future genetic and clinical research should focus on kindred with 3 or more affected individuals for better identification of the FNMTC susceptibility genes and to better guide management and screening recommendations.

Screening pregnant women in a high-risk population with WHO-2013 or NICE diagnostic criteria does not affect the prevalence of gestational diabetes.

There are currently several diagnostic criteria for gestational diabetes (GDM). Both the WHO -2013 and NICE diagnose GDM based on a single step 75 g OGT; however; each uses different glucose thresholds. Previous studies have shown that the prevalence of GDM using the NICE criteria (GDM-N) is lower than that using the WHO-2013 criteria (GDM-W). Qatar has national diabetes in pregnancy program in which all pregnant women undergo OGTT screening using the WHO-2013 criteria. This study aims to define the prevalence of GDM using both criteria in a high-risk population. This retrospective study included 2000 women who underwent a 75 g (OGTT) between Jan 2016 and Apr 2016 and excluded patients with known pre-conception diabetes, multiple pregnancy, and those who did not complete the OGTT. We then classified the women into GDM-W positive, GDM-N positive but GDM-W negative, and normal glucose tolerance (NGT) population. A total of 1481 women (74%) had NGT using the NICE or the WHO-2013 criteria. The number of patients who met both criteria was 279 subjects (14%) with a good agreement (Kappa coefficient 0.67, p < 0.001). The NICE and the WHO-2013 criteria were discordant in 240 subjects (12% of the cohort); 6.7% met the WHO -2013 criteria only and only 5.3% met the NICE criteria. The frequency of pre-eclampsia, pre-term delivery, Caesarean-section, LGA and neonatal ICU admissions were significantly increased in the GDM-W group. However, the GDM-N positive but GDM-W negative had no increased risk of maternal or fetal complications apart from pregnancy-induced hypertension. The WHO-2013 and the NICE criteria classified a similar proportion of pregnant women, 21.5% and 20.1%, respectively, as having GDM; however, they were concordant in only 14% of the cases. Women who are GDM-N positive but GDM-W negative are not at increased risk of maternal and fetal pregnancy complications, except for pregnancy-induced hypertension. As the NICE criteria are more specific to the UK population, we would recommend the use of the WHO-2013 criteria to diagnose GDM in the MENA region and possibly other regions that do not have the same set-up as the UK.

Pregnancy outcomes of early detected gestational diabetes: a retrospective comparison cohort study, Qatar.

OBJECTIVE: To compare pregnancy outcomes in patients with early versus usual gestational diabetes mellitus (GDM). DESIGN: A retrospective cohort study. SETTINGS: The Women's Hospital, Hamad Medical Corporation, Qatar. PARTICIPANTS: GDM women who attended and delivered in the Women's Hospital, between January and December 2016. GDM was diagnosed based on the 2013-WHO criteria. The study included 801 patients; of which, 273 E-GDM and 528 U-GDM. Early GDM (E-GDM) and usual GDM (U-GDM) were defined as GDM detected before and after 24 weeks' gestation, respectively. OUTCOMES: Maternal and neonatal outcomes and the impact of timing of GDM-diagnosis on pregnancy outcomes. RESULTS: At conception, E-GDM women were older (mean age 33.5±5.4 vs 32.0±5.4 years, p<0.001) and had higher body mass index (33.0±6.3 vs 31.7±6.1 kg/m2, p=0.0059) compared with U-GDM. The mean fasting, and 1-hour blood glucose levels were significantly higher in E-GDM vs U-GDM, respectively (5.3±0.7 vs 4.0±0.7 mmol/L, p<0.001 and 10.6±1.7 vs 10.3±1.6 mmol/L, p<0.001). More patients in the U-GDM were managed on diet alone compared with E-GDM (53.6% vs 27.5%, p<0.001). E-GDM subjects gained less weight per week compared with U-GDM (0.02±0.03 vs 0.12±0.03 kg/week, p=0.0274). Maternal outcomes were similar between the two groups apart from a higher incidence of preterm labour (25.5% vs 14.4%; p<0.001) and caesarean section (52.4% vs 42.8%; p=0.01) in E-GDM vs U-GDM, respectively. After correction for covariates; gestational age at which GDM was diagnosed was associated with increased risk of macrosomia (OR 1.06, 95% CI 1.00 to 1.11; p<0.05) and neonatal hypoglycaemia (OR 1.05, 95% CI 1.00 to 1.11; p<0.05). CONCLUSION: Our data support the concept of early screening and treatment of GDM in high-risk patients. More data are needed to examine the optimal time for screening.

The effect of vitamin D supplementation on the glycemic control of pre-diabetic Qatari patients in a randomized control trial.

BACKGROUND: Vitamin D deficiency is associated with indicators of pre-diabetes including, insulin resistance, ß-cell dysfunction and elevated plasma glucose with controversial findings from current trials. This study aims to investigate the long-term effect of vitamin D on glucose metabolism and insulin sensitivity in pre-diabetic and highly vitamin-deficient subjects. METHODS: One hundred thirty-two participants were randomized to 30,000 IU vitamin D weekly for 6 months. Participants underwent oral glucose tolerance test (OGTT) at 3-month intervals to determine the change in plasma glucose concentration at 2 h after 75 g OGTT (2hPCG). Secondary measurements included glycated hemoglobin, fasting plasma glucose and insulin, post-prandial insulin, indices of insulin sensitivity (HOMA-IR, Matsuda Index), ß-cell function (HOMA-ß, glucose and insulin area under the curve (AUC), disposition and insulinogenic indices), and lipid profile. RESULTS: A total of 57 (vitamin D) and 75 (placebo) subjects completed the study. Mean baseline serum 25(OH) D levels were 17.0 ng/ml and 14.9 ng/ml for placebo and vitamin D group, respectively. No significant differences were observed for 2hPC glucose or insulin sensitivity indices between groups. HOMA-ß significantly decreased in the vitamin D group, while area under curve for glucose and insulin showed a significant reduction in ß-cell function in both groups. Additionally, HOMA-ß was found to be significantly different between control and treatment group and significance persisted after adjusting for confounding factors. CONCLUSION: Vitamin D supplementation in a pre-diabetic and severely vitamin-deficient population had no effect on glucose tolerance or insulin sensitivity. The observed reduction in ß-cell function in both placebo and vitamin D groups could be attributed to factors other than supplementation.

A CASE OF HYPERPARATHYROIDISM TREATED WITH CINACALCET DURING PREGNANCY.

OBJECTIVE: Hyperparathyroidism during pregnancy is associated with increased maternal and neonatal complications. Cinacalcet is a calcimimetic medication that is used in the treatment of hyperparathyroidism; its use in pregnancy is limited to a few case reports. METHODS: Case report and literature review. RESULTS: We are reporting on a 37-year-old patient who was admitted to the hospital with dyspnea at 24 weeks gestation. A routine blood test revealed hypercalcemia; corrected calcium level was 3.17 mmol/L, and parathyroid hormone was elevated at 168 pg/mL. The patient was asymptomatic. Following her last delivery 10 years previously, her newborn developed severe tetany and needed treatment with intravenous (IV) calcium. Neck ultrasound was normal. Due to obesity and history of recurrent deep venous thrombosis, neck exploration was not favored. Initial treatment included calcitonin and IV fluids. The aim was to keep her calcium level as normal as possible to avoid any fetal complications. She was started on cinacalcet 15 mg once per day, which was increased later to 15 mg twice daily. By 36 weeks gestation, corrected calcium levels were down to <2.60 mmol/L. The patient was scheduled to deliver via elective cesarean section at 38 weeks, but she presented at 37 weeks in labor pain and delivered via emergency cesarean section. Postdelivery, the neonate calcium levels remained normal. CONCLUSION: During pregnancy, parathyroid surgery is the recommended treatment. Cinacalcet could be one of the options in severe cases of hypercalcemia if surgery cannot be performed. Further studies are needed to examine the safety of cinacalcet in pregnancy.

Type 2 diabetes mellitus in pregnancy: The impact of maternal weight and early glycaemic control on outcomes.

OBJECTIVES: To study the pregnancy outcomes in women with type 2 diabetes mellitus (T2DM) and to relate these to maternal risk factors. METHODS: We conducted a retrospective study of 419 women with T2DM (index group)- who attended our diabetes in pregnancy clinic at the Hamad Women's Hospital, Doha, between March 2015 and December 2016 -and 1419 normoglycaemic women (control group). RESULTS: Compared with the controls, T2DM women were older (mean age 34.7 ± 6.9 vs 29.6 ± 5.5 years; p < 0.001) and had a higher BMI (34.5 ± 6.7 vs 28.8 ± 6.1 kg/m2; p < 0.001). The incidence of macrosomia, shoulder dystocia and stillbirth were similar in the two groups, while that of pre-term labour, pre-eclampsia, caesarean section (CS), large for gestational age (LGA), neonatal ICU (NICU) admission, and neonatal hypoglycaemia were significantly higher in the T2DM compared to the control group (p < 0.05). Multivariate regression analysis showed that first trimester HbA1C was associated with an increased risk of LGA (OR 1.17; 95% CI [1.01-1.36]), pre-eclampsia (OR 1.26; 95% CI [1.02-1.54]), neonatal hypoglycaemia (OR 1.32; 95% CI 1.10-1.60) and NICU admission (OR 1.32; 95% CI 1.10-1.60). Pre-pregnancy BMI was associated with increased risk of LGA (OR 1.04; 95%CI [1.00-1.08]), macrosomia (OR 1.06; 95%CI [1.00-1.12]) and CS (OR 1.05; 95% CI [1.01-1.09]). Last trimester HbA1c was associated with an increased risk of LGA [OR 1.53, 95% CI [1.13-2.10)] and CS (OR 1.37, 95% CI [1.01-1.87]). CONCLUSION: T2DM is associated with adverse pregnancy outcomes compared to the normal control in Qatar. Maternal obesity and glycaemic control before and during pregnancy are the main determinants of pregnancy outcomes in women with T2DM.

A pilot study using flash continuous glucose monitoring in patients with type-2 diabetes on multiple anti-diabetic agents during Ramadan.

BACKGROUND: This study aims to examine the incidence of hypoglycaemia, based on activity, during Ramadan in patients with type 2 diabetes mellitus who were on were on three or more anti-diabetic medications. METHODS: Type 2 diabetes patients who fasted during Ramadan and were on three or more anti-diabetic medications were studied for two weeks using flash glucose monitoring. The patients were asked to document all episodes of hypoglycaemia and were classified as active or sedentary according to their daytime activity. RESULTS: The study included 16 patients of whom 10 were active and 6 were sedentary. There were 13 males and 3 females; mean age was 53.4 ±â€¯6.4 years; mean diabetes duration was 15 ±â€¯5.9 years, and mean HbA1C was 7.9 ±â€¯1.3%. Over the two weeks; there were 7.9 episodes of hypoglycaemia recorded per patient; 50% of which were asymptomatic. There was no difference at baseline in age, BMI, HBA1C, diabetes duration, and anti-diabetic medications between the active and sedentary groups. The active group had better glucose control; median blood glucose was (7.1 (5.1-8.5) vs 10.6 (9.6-11.5) mmol p < 0.01), mean estimated HBA1C was (6.2 ±â€¯1.2% vs 8.3 ±â€¯1.0%; p = 0.047). The active group had more episodes of hypoglycaemia compared to the sedentary group (11.6 vs 1.8 hypo episode per patient/two weeks; p = 0.019); most of which were asymptomatic. CONCLUSION: Patients with type 2 diabetes mellitus who are on three or more anti-diabetic medications should be warned about the increased risk of asymptomatic hypoglycaemia during Ramadan. Anti-diabetic medication adjustments during Ramadan should take into account the degree of activity. Flash glucose monitoring system can help patients to fast safely during Ramadan and detect asymptomatic hypoglycaemia.

Incidence of hypoglycaemia in patients with type-2 diabetes taking multiple glucose lowering therapies during Ramadan: the PROFAST Ramadan Study.

OBJECTIVE: To assess the incidence of hypoglycemia in people with type-2 diabetes mellitus (T2DM) on three or more anti-diabetic medications during Ramadan. STUDY DESIGN METHODS: We have studied people with T2DM on three or more glucose-lowering drugs during Ramadan of H1438 (May-June 2017). The dose of each drug was adjusted according to a pre-specified protocol. The incidence of symptomatic or blood glucose confirmed hypoglycemia was recorded during the study. RESULTS: We enrolled 228 people with T2DM; 181 completed the study, and data on hypoglycaemia was available in 172 subjects. There were 115 males and 66 females, (mean age ± SD) 53.6 ± 9.7 years, diabetes duration 10 ± 6 yrs. The incidence of hypoglycaemia was 16.3% (28/172). Univariable logistic regression analysis showed that the risk of hypoglycaemia was increased in Arab subjects compared to Qatari; in those with longer duration of diabetes; and in those on four or more anti-diabetic medications compared to those on three anti-diabetic medications. CONCLUSION: Despite the tailored advice, there is a high incidence of hypoglycemia in people with T2DM taking multiple glucose lowering therapies whilst fasting during Ramadan. Guidelines should address the increased complexity in anti-diabetic medications in patients who fast during Ramadan. Healthcare providers should individualize the modifications in anti-diabetic medications during Ramadan.

Atypical Complications of Graves' Disease: A Case Report and Literature Review.

Graves' disease (GD) may display uncommon manifestations. We report a patient with rare complications of GD and present a comprehensive literature review. A 35-year-old woman presented with a two-week history of dyspnea, palpitations, and edema. She had a raised jugular venous pressure, goiter, and exophthalmos. Laboratory tests showed pancytopenia, a raised alkaline phosphatase level, hyperbilirubinemia (mainly direct bilirubin), and hyperthyroidism [TSH: <0.01 mIU/L (reference values: 0.45-4.5), fT4: 54.69 pmol/L (reference values: 9.0-20.0), and fT3: >46.08 pmol/L (reference values: 2.6-5.7)]. Her thyroid uptake scan indicated GD. Echocardiography showed a high right ventricular systolic pressure: 60.16 mmHg. Lugol's iodine, propranolol, cholestyramine, and dexamethasone were initiated. Hematologic investigations uncovered no reason for the pancytopenia; therefore, carbimazole was started. Workup for hepatic impairment and pulmonary hypertension (PH) was negative. The patient became euthyroid after 3 months. Leukocyte and platelet counts and bilirubin levels normalized, and her hemoglobin and alkaline phosphatase levels and right ventricular systolic pressure (52.64 mmHg) improved. This is the first reported single case of GD with the following three rare manifestations: pancytopenia, cholestatic liver injury, and PH with right-sided heart failure. With antithyroid drugs treatment, pancytopenia should resolve with euthyroidism, but PH and liver injury may take several months to resolve.

Choriocarcinoma syndrome: a case report and a literature review.

A 35-year-old Qatari man presented to our hospital with a 4-month history of mild abdominal pain, weight loss, and jaundice. He was found to have central intra-abdominal mass and a single testis in the scrotum. His investigations showed cholestatic jaundice and very high level of ß -HCG (1131379 IU/L). CT scans of the chest and abdomen showed a huge pelvic-abdominal mass with extensive retroperitoneal lymphadenopathy, in addition to liver and lung metastases. CT-guided Tru-Cut biopsy of the mass showed mixed germ cell tumor. Chemotherapy was refused by the patient and his family. In the following days, the patient bled from his liver metastases leading to hemorrhagic shock, hemorrhage from metastatic sites of choriocarcinoma containing tumors is named choriocarcinoma syndrome. He was transferred to the medical intensive care unit, where he was intubated and resuscitated. Embolization of the right hepatic artery was done, but failed to control the bleeding, which continued with development of disseminated intravascular coagulopathy and a severe abdominal compartment syndrome, and eventually the patient died.

Ischaemic hepatitis precipitated by recurrent episodes of atrial fibrillation.

We report a case of ischaemic hepatitis associated with recurrent fast atrial fibrillation (AF) episodes in a 59-year-old male who presented with shortness of breath, nausea and vomiting. The patient had a history of ischaemic cardiomyopathy. An emergency electrocardiogram showed fast AF with a ventricular rate of 190 min(-1). The aspartate aminotransferase (AST) level was 2222Ul(-1), alanine aminotransferase (ALT) was 1255Ul(-1), lactate dehydrogenase (LDH) was 1842Ul(-1) and serum creatinine was 150 µmoll(-1). An ultrasound of the abdomen showed an enlarged liver with hypoechoic lesions. The patient received digoxin. In the next few days, while liver enzymes and serum creatinine started to return to normal levels, the patient had two attacks of fast AF, each associated with elevated liver enzymes and a concomitant rise in serum creatinine. The patient was transferred to the intensive care unit to improve control of his AF, after which his liver enzymes and renal function gradually returned to normal.
