Diabetes and Ramadan: Practical guidelines 2021.

Fasting during Ramadan is one of the five pillars of Islam and is obligatory for all healthy Muslims from the age of puberty. Though individuals with some illness and serious medical conditions, including some people with diabetes, can be exempted from fasting, many will fast anyway. It is of paramount importance that people with diabetes that fast are given the appropriate guidance and receive proper care. The International Diabetes Federation (IDF) and Diabetes and Ramadan (DaR) International Alliance have come together to provide a substantial update to the previous guidelines. This update includes key information on fasting during Ramadan with type 1 diabetes, the management of diabetes in people of elderly ages and pregnant women, the effects of Ramadan on one's mental wellbeing, changes to the risk of macrovascular and microvascular complications, and areas of future research. The IDF-DAR Diabetes and Ramadan Practical Guidelines 2021 seek to improve upon the awareness, knowledge and management of diabetes during Ramadan, and to provide real-world recommendations to health professionals and the people with diabetes who choose to fast.

Characteristics of patients with coexisting DNAJB9-associated fibrillary glomerulonephritis and IgA nephropathy.

BACKGROUND: Coexistence of fibrillary glomerulonephritis (FGN) and immunoglobulin A (IgA) nephropathy (IgAN) in the same kidney biopsy (FGN-IgAN) is rare, and the clinicopathologic characteristics and outcome of this dual glomerulopathy are unknown. METHODS: In this study, 20 patients with FGN-IgAN were studied and their characteristics were compared with 40 FGN and 40 IgAN control patients. RESULTS: Concurrent IgAN was present in 1.8% of 847 consecutive FGN cases and was the second most common concurrent glomerulopathy after diabetic nephropathy. FGN-IgAN patients were overwhelmingly White (94%) and contrary to FGN patients were predominantly (60%) males. Compared with IgAN patients, FGN-IgAN patients were older, had higher proteinuria, a higher incidence of renal insufficiency, and a lower incidence of microhematuria and gross hematuria at diagnosis. Six (30%) patients had malignancy, autoimmune disease or hepatitis C infection, but none had a secondary cause of IgAN or clinical features of Henoch-Schonlein purpura. Histologically, all cases exhibited smudgy glomerular staining for immunoglobulin G and DnaJ homolog subfamily B member 9 (DNAJB9) with corresponding fibrillary deposits and granular mesangial staining for IgA with corresponding mesangial granular electron-dense deposits. On follow-up (median 27 months), 10 of 18 (56%) FGN-IgAN patients progressed to end-stage kidney disease (ESKD), including 5 who subsequently died. Serum creatinine at diagnosis was a poor predictor of renal survival. The proportion of patients reaching ESKD or died was higher in FGN-IgAN than in IgAN. The median Kaplan-Meier ESKD-free survival time was 44 months for FGN-IgAN, which was shorter than IgAN (unable to compute, P = 0.013) and FGN (107 months, P = 0.048). CONCLUSIONS: FGN-IgAN is very rare, with clinical presentation and demographics closer to FGN than IgAN. Prognosis is guarded with a median renal survival of 3.6 years. The diagnosis of this dual glomerulopathy requires careful evaluation of immunofluorescence findings, and electron microscopy or DNAJB9 immunohistochemistry.

Systemic histoplasmosis: a 15-year retrospective institutional review of 111 patients.

To our knowledge, an institutional review of systemic histoplasmosis has not been conducted in the United States since the major outbreaks in Indianapolis in 1978-4982. We conducted a retrospective review of all patients with systemic histoplasmosis diagnosed at Mayo Clinic over a 15-year period. The case definitions employed were based on an international consensus statement by the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group (EORTC/IFICG) and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (MSG). One hundred eleven patients with systemic histoplasmosis were identified between January 1, 1991, and December 31, 2005. Of these, 78 patients had disseminated histoplasmosis and 55 patients had Histoplasma capsulatum fungemia. The mean age of patients was 55 years, 66% were male, and 98% were white. Fifty-nine percent of patients were immunocompromised. Fever was the most frequently reported symptom (63%), followed by respiratory complaints (43%) and weight loss (37%). The peripheral white blood cell count was <3000 cells/mm in 28%, hemoglobin was <10 g/dL in 29%, and platelet count was <150,000 cells/mm in 41% of patients. Liver enzymes were elevated (alanine aminotransferase >60 U/L in 39%, aspartate aminotransferase >60 U/L in 27%), alkaline phosphatase was >200 U/L in 55%, and albumin was <3.5 g/dL in 70%. Serologic and histopathologic examinations were each positive in 75% of cases, Histoplasma urine antigen screening was positive in 80%, and H. capsulatum was culture positive in 84%. Forty-seven percent of patients were sequentially treated with an amphotericin B-containing product followed by itraconazole, 31% received itraconazole alone, and 7% received an amphotericin B-containing product only. Another 13% of patients did not receive antifungal treatment, and the remaining 2% did not have treatment data available. Sixty percent of patients required hospitalization, and in hospital mortality was 6% with a median survival time of 61 days. The relapse rate was 9%, with a median relapse-free survival of 857 days. Systemic histoplasmosis should be suspected in patients who have lived in endemic areas with fever, bone marrow suppression, and elevated hepatic enzymes, particularly if they are immunocompromised. Evaluation including a combination of Histoplasma serologic screening, urine antigen assay, and fungal culture will secure the diagnosis in most cases.

Intraoperative hypotension and prolonged operative time as risk factors for slow graft function in kidney transplant recipients.

BACKGROUND: Slow graft function (SGF) is an immediate post-operative complication of cadaveric kidney transplantation pre-disposing to acute rejection (AR) and lower graft survival. The objective of this study was to test whether intraoperative hypotension and/or prolonged operative time are risk factors for SGF in patients post-cadaveric kidney transplant. METHODS: This was a single center retrospective case-control study of patients post-cadaveric kidney transplant performed at the University of Kansas Medical Center (KUMC) between January 2002 and February 2005. Data were retrieved from the United Network of Organ Sharing (UNOS) database. RESULTS: One hundred and sixty patients underwent cadaveric kidney transplant. Intraoperative measurements including blood pressure and operative time were available in 94 patients of which 57 had immediate graft function (IGF) and 37 had SGF (defined as decline in serum creatinine (Cr) of <50% by day 3). In multivariate logistic regression analysis, intraoperative hypotension and prolonged operative time were additive independent risk factors for SGF. For every 5 mmHg increment decrease in blood pressure, the odds ratio (OR) for SGF was 1.28 (95% confidence interval (CI): 1.08-1.53) for systolic blood pressure (SBP), 1.38 (CI: 1.06-1.79) for diastolic blood pressure (DBP), and 1.51 (CI: 1.15-1.99) for mean arterial pressure (MAP). For every 30 min increase in operative time, the OR for SGF was 1.35 (CI: 1.07-1.71). CONCLUSION: Intraoperative hypotension and prolonged operative time are independent risk factors for SGF in patients post-cadaveric kidney transplant.
