Venous thromboembolism during mycoplasma pneumoniae infection: case report and review of the literature

Mycoplasma pneumoniae infection is frequent but generally mild or self-limiting. Approximately 10% of cases develop clinical signs of pneumonia with "atypical" radiographic pattern. However, mycoplasma pneumoniae can be responsible for a variety of extrapulmonary manifestations, potentially involving all systems and apparatuses. Although exact pathophysiological mechanisms are not completely known, these could be secondary to direct invasion of the target organ, immunological damage due to molecular mimicry or vascular obstruction. A 45-year-old man was admitted to Internal Medicine Unit because of fever, dry cough and fatigue lasting 15 days. Fever disappeared after starting clarithromycin. About 72 h after admission the patient complained of right calf pain and tachypnea. The presence of anti-mycoplasma antibodies suggested mycoplasma pneumoniae infection. Moreover, a diagnosis of venous thrombo-embolism was performed. Given the absence of classical risk factors for thrombosis, patient was investigated for inherited and acquired thrombophilia and tested positive for antiphospholipid antibodies. A review of the English literature on the association between m. pneumoniae and pulmonary embolism will be provided in order to underline the possible pathogenetic role of antiphospholipid antibodies in this setting. Clinicians should outweigh risk and benefits for LMWH prophylaxis case by case considering these adjunctive pro-thrombotic mechanisms in patients m. pneumoniae infection.

Madelung's disease and acute alcoholic hepatitis: case report and review of literature

Madelung's disease is a rare condition characterized by symmetric growth of fatty tumors (lipomas) around the neck, shoulders, upper arms, and trunk. It often affects men with a history of alcohol abuse. Here we report a review of the literature about this disease together with the description of a patient affected by Madelung's disease and acute alcoholic hepatitis.

Reduced glomerular filtration rate and prior cardiovascular event entail similar risk for coronary atherosclerotic burden

OBJECTIVE

Prior cardiovascular event and kidney dysfunction are both strong risk factors for coronary artery disease. The aim of this study is to assess coronary atherosclerotic burden in a large population of patients undergoing coronary angiography, according to prior cardiovascular event or chronic kidney disease.

PATIENTS AND METHODS

We evaluated 700 consecutive patients who underwent coronary angiography (CA). Serum creatinine to estimate glomerular filtration rate (eGFR) was measured. Clinically significant coronary artery disease (CAD) was defined by the presence of a coronary lesion resulting in a luminal stenosis >50%. For the purpose of the study, the whole population was divided into 4 subgroups according to the presence/absence of eGFR <60 ml/min/1.73 m2 or prior cardiovascular event: eGFR≥60/no event (Group A), eGFR≥60/yes event (Group B), eGFR<60/no event (Group C), eGFR<60/yes event (Group D).

PATIENTS

As expected, patients in group D had the worst clinical and biochemical profile. These patients also presented the highest values of urinary albumin creatinine ratio (ACR, p<0.001) and the lowest values of eGFR (p<0.01). One-hundred-ninety-six patients had three-vessel disease. Patients who had undergone PCI procedure showed a lower eGFR as compared to patients who had not (p=0.009). Considering group A as reference, the risk of having three-vessel disease was increased in group B (OR= 2.09; 95% CI 1.37-3.19), in group C, (OR= 1.80; 95% CI 1.04-3.14), and finally in group D (OR= 3.35; 95% CI 2.01-5.58). The risk carried by group C was not significantly different from that carried by Group B: OR= 0.86; 95% CI 0.5-1.5.

CONCLUSIONS

In our study, low eGFR seems to have the same excess risk of prior CV event.

MEDS score and vitamin D status are independent predictors of mortality in a cohort of Internal Medicine patients with microbiological identified sepsis

OBJECTIVE

Sepsis is a life-threatening disease resulting from the interaction between pathogen and host response; its dysregulation causes organ dysfunction, high morbidity, and mortality. Despite the increase of septic patients admitted to Internal Medicine wards, data about clinical predictors of mortality in this setting are still lacking. The aim of this study was to evaluate the role of MEDS score and vitamin D as predictors of mortality (28-day and 90-day) in septic patients admitted to the Internal Medicine department.

PATIENT S AND METHODS

Prospectively collected clinical data, lab tests including vitamin D, and clinical scores (SIRS, MEDS, SCS, REMS, SOFA, qSOFA) were retrospectively analyzed. Eighty-eight microbiologically identified septic patients (median age 75 years old, IQR 65-82 years old; range 37-94 years old) were evaluated.

RESULTS

Twenty-three patients (26.1%) died at 28 days, 33 (37.5%) died at 90 days. The logistic regression showed a positive effect of MEDS score (p=0.006; OR 1.24, 95% CI 1.08-1.49), and a negative effect of low vitamin D levels (p=0.008, OR 0.83, 95% CI 0.72-0.94) on mortality. Moreover, the cut-off of 7 points for MEDS score and of 7 ng/ml for vitamin D levels significantly predicted poor prognosis at 28 and 90 days.

CONCLUSIONS

MEDS score and vitamin D levels represent independent predictors of mortality in a cohort of Internal Medicine septic patients. Further studies on larger samples are needed to confirm our results and to clarify the pathophysiological mechanisms at the basis of vitamin D deficiency as a predictor of mortality in septic patients.

Paradoxical embolism with thrombus stuck in a patent foramen ovale: a review of treatment strategies

OBJECTIVE

Paradoxical embolism represents a rare condition occurring when a thrombus originating from venous system produces pulmonary embolism and systemic embolization through an intracardiac or pulmonary shunt. The evidence of a thrombus entrapped in a patent foramen ovale (PFO) is an even more rare condition. There is uncertainty about the optimal treatment strategy.

PATIENTS AND METHODS

A 58-year-old male patient was admitted to our Internal Medicine Unit with the diagnosis of bilateral bronchopneumonia. During hospitalization, the co-occurrence of chest pain and amaurosis led us to hypothesize a paradoxical embolism.

RESULTS

Transthoracic echocardiography showed the presence of a thrombus stuck over the interatrial septum. A contrast-enhanced chest CT scan showed multiple pulmonary embolisms and brain CT scan documented a hypodense area, of ischemic significance, in the left occipital lobe near tentorium. In order to prevent further embolization, emergency cardiac surgery (right atriotomy, removal of thrombus and closure of the PFO, pulmonary thrombectomy) was performed without complications.

CONCLUSIONS

Although rare, the evidence of a thrombus stuck in a patent foramen ovale represents a clinical emergency. The optimal therapeutic approach is still debated. The surgical correction seems to be a safe and effective option for these patients.

Dental health in patients affected by alcohol use disorders: a cross-sectional study

OBJECTIVE

Chronic alcohol abuse represents a risk factor for oral diseases, in particular, oral cancer. Periodontal disease has been showed to be involved in the pathophysiology of cardiovascular and metabolic diseases, such as atherosclerosis and liver steatosis. The role of chronic alcohol consumption on periodontitis is still controversial. The aim of the study was to evaluate the effect of chronic alcohol abuse on oral health.

PATIENTS AND METHODS

Twenty-three alcohol use disorders (AUD) patients and twenty-three healthy social drinkers underwent an oral examination by trained oral clinicians in order to evaluate oral and dental health. A questionnaire assessing oral hygiene was administered together with the evaluation of DMFT (decayed, missing, filled teeth), SLI (Silness-Loë plaque index) and CPI (community periodontal index of treatment needs) scores.

RESULTS

Alcoholic patients showed significantly lower oral hygiene scores compared to controls. Alcoholic patients showed significantly poorer scores at DMFT, SLI and CPI tests. Moreover, among alcoholics, smokers showed a significantly poorer oral health than non-smokers.

CONCLUSIONS

Chronic alcohol abuse increases the risk of dental and periodontal diseases. Smoking represents a significant co-factor. The practice of basic oral hygiene and the access to professional dental care should be encouraged among AUD patients in order to reduce oral diseases.

Penicillamine-Related Lichenoid Dermatitis and Utility of Zinc Acetate in a Wilson Disease Patient with Hepatic Presentation, Anxiety and Spect Abnormalities

Wilson disease is an autosomal recessive disorder of hepatic copper metabolism with consequent copper accumulation and toxicity in many tissues and consequent hepatic, neurologic and psychiatric disorders. We report a case of Wilson disease with chronic liver disease; moreover, in our patient, presenting also with high levels of state anxiety without depression 99mTc-ECD-SPECT showed cortical hypoperfusion in frontal lobes, more marked on the left frontal lobe. During the follow-up of our patient, penicillamine was interrupted after the appearance of a lichenoid dermatitis, and zinc acetate permitted to continue the successful treatment of the patient without side-effects. In our case the therapy with zinc acetate represented an effective treatment for a Wilson disease patient in which penicillamine-related side effects appeared. The safety of the zinc acetate allowed us to avoid other potentially toxic chelating drugs; this observation is in line with the growing evidence on the efficacy of the drug in the treatment of Wilson disease. Since most of Wilson disease penicillamine-treated patients do not seem to develop this skin lesion, it could be conceivable that a specific genetic factor is involved in drug response. Further studies are needed for a better clarification of Wilson disease therapy, and in particular to differentiate specific therapies for different Wilson disease phenotypes.

Human Rickettsia aeschlimannii infection: first case with acute hepatitis and review of the literature

OBJECTIVE

Rickettsia conorii is responsible for the Mediterranean Spotted Fever. Recently, new rickettsial species have been recognized in Europe and implicated in human diseases. Clinical features often differ greatly from each other, but non-severe liver involvement is frequently observed during any rickettsial infection.

CASE REPORT

We describe the unique case of a patient presented with significant high aminotransferase levels due to the first human R. aeschlimannii infection ever detected in Italy. The hypothesis of rickettsiosis was made on the basis of a comprehensive medical history and was confirmed by serological tests. Molecular analyses made on a sample of hepatic tissue revealed the presence of a rickettsial species never found before in human liver.

CONCLUSIONS

A brief review of the literature is reported to highlight how relevant this case is and to remind that rickettsioses should be in the differential diagnoses of acute hepatitis, considering mostly the recent spread of new rickettsial species.

Review article: Alcohol and gut microbiota - the possible role of gut microbiota modulation in the treatment of alcoholic liver disease

BACKGROUND

Alcohol abuse represents the most common cause of liver disease in the Western countries. Pre-clinical and clinical studies showed that alcohol consumption affects amount and composition of gut microbiota. Moreover, gut flora plays an important role in the pathogenesis of alcoholic liver injury.

AIM

To review the relationship between alcohol administration and changes on gut microbiota, its involvement in the pathogenesis of alcoholic liver disease, and how gut microbiota modulation could be a target for the treatment of alcoholic liver disease.

METHODS

Articles were identified using the PubMed database with the search terms 'Alcohol', 'Gut Microbiota', 'Alcoholic liver disease', 'Probiotic', 'Prebiotic', 'Symbiotic' and 'Antibiotic'. English-language articles were screened for relevance. Full review of publications for the relevant studies was conducted, including additional publications that were identified from individual article reference lists.

RESULTS

Alcohol abuse induces changes in the composition of gut microbiota, although the exact mechanism for this alteration is not well known. The translocation of bacterial products into the portal blood appears to play a key role in alcohol-induced liver damage. Several studies show that the modulation of gut microbiota seem to be a promising strategy to reduce alcohol-induced liver injury.

CONCLUSIONS

Further studies are needed to better understand the relationship between alcohol administration and changes in gut microbiota, and its involvement in alcoholic liver disease. Moreover larger studies are needed to confirm the preliminary results on the therapeutic effects of gut microbiota modulation.

Novel strategies to treat alcohol dependence with sodium oxybate according to clinical practice

OBJECTIVE

The treatment of alcohol dependence (AD) with sodium oxybate (SMO) was introduced in Italy and Austria more than 20 years and 15 years ago respectively, and it is now widely employed. In addition to the data obtained from clinical trials, little information is available on specific clinical practices. Thus, the aim of this study was to present and discuss the results of a consensus meeting held after twenty years of using SMO in clinical practice in Italy.

MATERIALS AND METHODS

A validated questionnaire study was conducted to investigate the modalities of treatment of AD with SMO currently used in Italy. A group of four referees first drew up the questionnaire which was distributed to fifty experts in the field of alcohol use disorders. The questionnaire consisted of 125 items with five different modalities of response and two or three answer possibilities.

RESULTS

The results of this survey showed a broad consensus on some issues regarding, for example, the duration of treatment, and the dose regimen of the drug; however, some aspects of the treatment of AD with SMO still remain controversial.

CONCLUSIONS

This is the first consensus study investigating the use of SMO for the treatment of AD through the opinions gained in over twenty years of clinical practice provided by fifty Italian expert clinicians. A consensus on good practice for the correct administration of SMO has clearly emerged; these opinions, along with those derived from previous clinical investigations, will help physicians to use SMO in a better way. However, some issues remain controversial, and others remain unresolved.

State and trait anxiety and depression in patients affected by gastrointestinal diseases: psychometric evaluation of 1641 patients referred to an internal medicine outpatient setting

OBJECTIVES

To evaluate state and trait form of anxiety and current depression in patients affected by gastrointestinal diseases.

METHODS

We studied 1641 outpatients with gastrointestinal disorders, consecutively referred to our Internal Medicine outpatients from 1997 to 2005. State and trait anxiety were assessed by the State and Trait Anxiety Inventory. Current depression was assessed by the Zung self-rating depression scale.

RESULTS

Among patients, 1379 (84.1%) showed state anxiety, 1098 (67%) showed trait anxiety and 442 (27%) showed current depression. The number of gastrointestinal diseases was directly correlated to state anxiety (p < 0.001) and trait anxiety (p = 0.04). Females showed higher levels of anxiety and depression than males (p < 0.001). State anxiety was related to food allergies (p < 0.001), small intestinal bacterial overgrowth (SIBO) (p = 0.001), Hp infection (p = 0.01) and ulcerative colitis in active phase (p = 0.03). Trait anxiety was related to irritable bowel syndrome (IBS) (p < 0.001), Helicobacter pylori (Hp) infection (p = 0.001), food allergies (p = 0.001) and SIBO (p = 0.001). Current depression was related to IBS (p < 0.001) and coeliac disease (p = 0.01), SIBO (p = 0.02). A predicted probability of 0.77 +/- 0.16 to have state anxiety, of 0.66 +/- 0.12 to have trait anxiety and of 0.39 +/- 0.14 to have depression was found in these patients.

CONCLUSIONS

Most of the patients who seek medical consultation for gastrointestinal problems show an associated affective disorder. These patients should be managed by a team including gastroenterologists, psychologists and/or psychiatrists, or by a gastroenterologist having expertise in the treatment of psychological disorders.
