ABSTRACT

BACKGROUND: Masked hypertension (MHTN) and lack of nocturnal dipping in blood pressure (BP) have been linked to the state of inflammation. AIMS: We aimed to assess the frequency of nocturnal patterns of BP and heart rate (HR) in patients with IBD. METHODS: Sixty-three normotensive patients with confirmed IBD during remission and 63 healthy subjects were enrolled in a case-control study. All subjects were monitored for BP and HR over a period of 24 h under ambulatory setting. Means for BP and HR were calculated for nighttime and daytime periods. Daytime BP ≥ 135/85 mmHg, nighttime BP ≥ 120/70 mmHg, and 24-h average BP ≥ 130/80 mmHg were defined as MHTN. The main end points of this study were lack of >10% nocturnal decrease in the systolic BP (NDP-BP) and in HR (NDP-HR). RESULTS: After exclusion of 8 patients with IBD from analysis, 55 patients and 63 control subjects (49% men) with a mean age of 37.5 ± 11.0 years were enrolled. NDP-BP was more common in the IBD group compared to controls (55 vs. 33%; P = 0.026). MHTN was detected in 24% of IBD patients compared to 8% among controls (P = 0.017). Meanwhile, NDP-HR was observed in 22% of the IBD patients and 30% of the control group (P = 0.402). IBD remained a significant predictor of NDP-BP (odds ratio 2.60, 95% confidence interval 1.19-5.51) following an adjustment for age and gender. CONCLUSIONS: IBD is associated with higher frequency of NDP-BP and MHTN; however, nocturnal changes in HR were similar in both groups.

ABSTRACT

OBJECTIVES: Familial Mediterranean fever (FMF), an inherited autosomal recessive disorder, is frequently present among individuals of Mediterranean origin. Differences in the clinical manifestations of FMF between different ethnic groups have been documented. The aim of the present study was to determine the most common characteristics of FMF and the relationship between clinical findings and the most common mutant alleles of the MEFV gene in an Iranian Azeri Turk population. MATERIALS AND METHODS: We analyzed clinical and genetic data from 415 patients identified as having FMF clinical symptoms and who were referred to the Molecular Genetics Laboratory of Tabriz/Iran over the last 3 years. The mutation type and clinical characteristics were determined for each patient. RESULTS: The following primary clinical characteristics of the patients were observed peritonitis was observed in 378 (93.8%), high-grade fever in 351 (86.88%), arthritis in 215 (54.57%), pleuritis in 207 (53.49%), myalgia in 153 (41.69%), AA amyloidosis in 149 (40.16%), and erysipelas-like erythema in 54 (14.96%) subjects. A positive response to colchicines treatment was noted in 374 (95.1%) patients including 303 patients with two mutated alleles and 71 patients with one identified mutation. CONCLUSION: In contrast to previous studies, there was no significant association between M694V mutation and development of amyloidosis. The M680I/M680I, M680I, M694I, and M694V/R761H genotypes were found to be associated with the development of amyloidosis. These results indicate that physicians need to pay careful attention to patients with asymptomatic or mildly symptomatic FMF with these genotypes.
