Assessment of atherosclerosis by carotid intimomedial thickness in patients with rheumatoid arthritis.

OBJECTIVES: To determine the prevalence of subclinical (asymptomatic) atherosclerosis in patients with rheumatoid arthritis (RA) and to study the variables affecting such an occurrence. METHODS: Case control study which included 100 patients with RA having disease duration more than 5 years and 100 healthy age and sex matched controls. Cases and controls symptomatic for atherosclerosis or having traditional risk factors for atherosclerosis were excluded. Both cases and controls were subjected to carotid ultrasound examination in addition to detailed history and physical examination. RESULTS: The study population (both cases and controls) included 94 females and 6 males. The mean age of cases and controls was similar (44.06 +/- 11.32 years and 44.1 +/- 11.52 years). The mean disease duration was 155.04 +/- 48.8 months. The mean carotid intimo-medial thickness (CIMT) of the RA patients (0.519 +/- 0.18 mm) was significantly greater than the controls (0.387 +/- 0.085). Age and disease duration were the only factors found to significantly affect CCIMT. RA patients had higher prevalence of carotid plaques (21%) compared to controls (1%). Erosions on hand radiographs were the only significant predictor of plaques in patients with RA. CONCLUSION: Patients with RA exhibit premature atherosclerosis by way of increased CIMT and carotid plaques when compared to age and sex matched controls.

Congenital prepubic sinus: a case report

Congenital prepubic sinus is an exceptional disorder of uncertain origin. These sinuses may represent a variant of epispadiac duplication or dorsal urethral duplication of the urethra.We present a case of isolated blind ending prepubic congenital sinus in a 5-year-old male child; which revealed transitional epithelium lining proximally; and squamous epithelium distally. This entity presents with either an opening in the prepubic region and/or persistent mucoid discharge. Excision leads to a permanent cure

Role of anti cyclic citrullinated peptide antibodies in erosive disease in patients with rheumatoid arthritis.

BACKGROUND & OBJECTIVES: Antibodies to cyclic citrullinated peptide (CCP) are a recently described marker in rheumatoid arthritis (RA), which are said to connote aggressive disease. No data on these antibodies are available from India. We undertook this study to evaluate the role of second generation anti CCP antibodies (anti CCP-2) in predicting erosive disease in Indian patients with rheumatoid arthritis and to define their role in seronegative RA. METHODS: A total of 211 patients with established RA were evaluated in this cross-sectional study for radiographic erosions. A high percentage of seronegative RA patients (40%) were included to assess the role of anti CCP-2 antibodies in this subgroup. Radiographic damage was quantified using modified Sharp score. Apart from anti CCP-2 antibodies, other factors evaluated for their ability to predict erosions included rheumatoid factor (RF) positivity, disease duration, and disease modifying anti rheumatic drugs (DMARD) naïve period. RESULTS: Anti CCP-2 antibodies were seen in 80 per cent patients with RA. Predictors of erosive disease included anti CCP-2 antibody positivity and DMARD naïve period. Patients positive for both RF and anti CCP-2 antibodies had a higher prevalence of erosions as compared to patients positive for only one antibody or negative for both. In seronegative RA (RF absent), anti CCP-2 antibodies were seen in over 50 per cent patients and were associated with a higher incidence of erosive disease. INTERPRETATION & CONCLUSION: Our finding showed that anti CCP-2 antibodies were present in 80 per cent patients with established RA. These have an independent role in predicting erosive disease, especially in the seronegative subgroup.

Sjogren's syndrome presenting with interstitial lung disease.

We report a patient of primary Sjogren's syndrome presenting with interstitial lung disease. The clinical picture was dominated by respiratory symptoms leading to a delay in diagnosis.

Biological agents in rheumatoid arthritis.

Rheumatoid arthritis (RA) is the commonest inflammatory joint disease with considerable morbidity and mortality. Conventional disease-modifying antirheumatic drugs like methotrexate form the cornerstone of therapy. However, they have several limitations in terms of slow onset of action, adverse effects and modest remission and retention rates. Several cytokines are involved in the pathogenesis of RA. Biological agents that specifically inhibit the effects of tumour necrosis factor-a (TNF-a) or Interleukin-1 (IL-1) represent a major advancement in the treatment of RA. By targeting molecules that are directly involved in the pathogenesis of RA, these therapies are proving to be efficacious, highly specific and better tolerated than standard therapies. The use of these agents needs to be monitored carefully for possible side-effects, including the development of infections. Additional anti-cytokine agents for the treatment of RA are under further development.

Management of rheumatoid arthritis.

The past few years have witnessed a major change in the approach to the treatment of rheumatoid arthritis. The present focus is on early recognition and prompt treatment with disease-modifying antirheumatic drugs of which methotrexate continues to be the drug of choice. Leflunomide is an important recent addition to the list of available drugs. The use of combinations of disease-modifying antirheumatic drugs is gaining wide acceptance. A better understanding of the pathobiology of rheumatoid arthritis has led to the development of targeted therapies such as tumour necrosis factor blockers. There are robust data to show the clinical utility of tumour necrosis factor blockers in patients with rheumatoid arthritis.

Bleomycin-induced scleroderma.

Systemic sclerosis is a connective tissue disease, which can be triggered by environmental factors. We report one such case of bleomycin-induced scleroderma.

Spondylo-arthropathies.

Spondylo-arthropathies are a broad group of inflammatory diseases that primarily involve the axial skeleton and the sacro-iliac joints. The pattern of peripheral joint involvement in spondylo-arthropathies differs from rheumatoid arthritis. Spondylo-arthropathies are known to include several conditions like ankylosing spondylitis, reactive arthritis (including Reiter's syndrome), arthritis associated with psoriasis and inflammatory bowel disease, juvenile and also undifferentiated spondylo-arthropathies. The characteristic features of spondylo-arthropathies are absence of rheumatoid factor, inflammatory low backache, sacro-iliitis, peripheral arthritis, enthesopathy, tendency to familial aggregation and association with HLA-B27. ESR may be elevated and patients may exhibit anaemia of chronic inflammation. HLA-B27 is a useful adjunctive test. The radiologic interpretation is very important. Non-steroidal anti-inflammatory drugs and spinal exercises are the cornerstone of therapy. Intra-articular corticosteroids are helpful. Patients may be benefited from, sulfasalazine, methotrexate or azathioprine.

Panniculitides--a clinicopathologic study.

OBJECTIVES: To describe the clinical and pathologic features of panniculitides, an uncommon group of diseases, where the available Indian literature is sparse. MATERIAL AND METHODS: Prospective four years study of patients presenting with panniculitis to a large teaching hospital in North India. RESULTS: Erythema nodosum (EN) was the commonest panniculitis (79.3% cases) in our cohort. Other causes included erythema induratum, Weber Christian disease, cutaneous polyarteritis nodosa and panniculitis associated with Takayasu's arteritis and dermatomyositis-lupus overlap. Elevated ESR and leukocytosis were the common laboratory abnormalities encountered. Septal panniculitis without vasculitis was the most frequent histopathologic pattern observed. Patients of EN did well on nonsteroidal anti-inflammatory drugs while corticosteroids with or without azathioprine were used to treat other panniculitides. CONCLUSIONS: Physician awareness, clinical pattern recognition and histopathological confirmation, all play a key role in the identification and management of panniculitis.

Giant cell arteritis--a rare cause of fever of unknown origin in India.

Giant cell arteritis (GCA) is a systemic large vessel vasculitis. Awareness of various manifestations of GCA is essential for early recognition and prompt treatment so as to prevent complications like blindness. GCA is one of the relatively common causes of fever of unknown origin (FUO) in the elderly in USA and Europe. However, no such cases have been reported from India. A case of GCA presenting as FUO is reported and the literature reviewed.

A clinico-bacteriological study of peripheral tuberculous lymphadenitis.

OBJECTIVE: Tuberculous lymphadenitis is the commonest form of extra-pulmonary tuberculosis. It is most often caused by M. tuberculosis though several reports from other countries have shown mycobacteria other than tuberculosis (MOTT) to be responsible for a significant proportion of tuberculous lymphadenitis cases. The present study was conducted to find the prevalence of M. tuberculosis and MOTT as aetiological agents in patients with peripheral tuberculous lymphadenitis. METHODS: A total of 138 patients with tuberculous lymphadenitis were included in the study. Diagnosis of tuberculosis was established on the basis of fine needle aspiration cytology, histopathology, presence of mycobacteria on Ziehl Neelson stain or auramine rhodamine stain, or aspiration of pus with negative Gram's stain and pyogenic cultute with radiologic evidence of pulmonary tuberculosis. Mycobacterial cultures were performed on aspirated material and species identified using standard methods. RESULTS: Of 138 patients, single lymph nodal enlargement was found in 48.6% patients while others had more than one lymph nodes. Lymph nodes were matted in 26.8% cases while fluctuation could be elicited in 12.3% patients. Chest X-ray showed evidence of active pulmonary lesions or mediastinal lymphadenopathy in 28.3% cases. The fine needle aspiration cytology was positive for tuberculous lymphadenitis in 41.3% cases while it revealed granulomas or necrosis in another 13% cases. The Ziehl-Neelson and the auramine-rhodamine staining were positive in 19.6% and 26.8% patients, respectively. On culture, the lymph node aspirate was positive for Mycobacterium species in 40.6% patients. In all but two cases, the culture revealed presence of Mycobacterium tuberculosis. The other two cultures revealed growth of Mycobacterium fortuitum chelonae complex. Of the two HIV-positive patients, M. tuberculosis could be isolated in one case. CONCLUSION: Findings of this study suggest that M. tuberculosis is still the most common cause of tuberculous lymphadenitis and MOTT are responsible for very few cases. However, such studies need to be carried out frequently at various centres so as to see any periodic and geographic variations within India.

A study of autoimmune markers in hepatitis C infection.

BACKGROUND & OBJECTIVES: Hepatitis C virus (HCV) infection is associated with several autoimmune markers. Despite HCV being common in India, no information on this aspect is available. This study was undertaken to ascertain the frequency and clinical significance of autoimmune markers like rheumatoid factor (RF), antinuclear antibodies (ANA), antibodies to double stranded deoxyribonucleic acid (dsDNA), anti neutrophil cytoplasmic antibody (ANCA), anti smooth muscle antibodies (ASMA), anti liver kidney microsomal 1 antibodies (anti LKM1), anti gastric parietal cell antibodies (anti GPCA), anti mitochondrial antibodies (AMA), anti cardiolipin antibodies (ACL) and cryoglobulins in HCV infection and to determine the effect of treatment on these markers. METHODS: Twenty five patients with chronic hepatitis C and 25 healthy controls were studied. Cryoglobulins were detected by cryoprecipitation, RF by latex agglutination, anti dsDNA and ACL by ELISA while indirect immunofluorescence was used to detect all other autoantibodies. RESULTS: Eighteen patients (72%) demonstrated autoimmune markers. RF, cryoglobulins and anti LKM1 antibodies were the most frequently detected markers (in 32% patients each). ASMA, perinuclear ANCA (pANCA), ANA and anti GPCA were seen in 24, 20, 12 and 4 per cent patients respectively. None of the patients exhibited ACL, AMA or antibodies to dsDNA. No antibodies were detected in healthy controls. Sixty per cent of the patients had rheumatological symptoms. Of the seven patients followed up after treatment with alpha interferon, only two exhibited persistence of RF, while symptoms and other markers disappeared. INTERPRETATION & CONCLUSION: Rheumatological symptoms and autoimmune markers are common in HCV infection and are usually overlooked. Patients with unexplained joint pains and/or palpable purpura should be screened for HCV. Further studies are needed to delineate fully the link between infection and autoimmunity.

Seroepidemiology and active surveillance of dengue fever/dengue haemorrhagic fever in Delhi.

The aims of the present study were to carry out surveillance for dengue virus infection in adults with short-duration fever, and serological study of dengue virus infection in persons without fever. Patients were divided into two groups. Group 1 included patients above 12 years of age with fever of 2-12 days duration without any apparent cause. Of these, patients who presented with fever for 2-5 days were included for virus isolation (group 1a) while those who presented within 6-12 days of the onset of fever were included for the dengue-specific IgM serology (group 1b). Group 2 included a sample of population belonging to all age groups but without pyrexia and blood was collected for dengue-specific IgG serology. Twenty-six patients were enrolled in group 1a over a period of 4 months (September to December, 1997). Of these, DEN1 was isolated in 5 cases. Group 1b included 182 patients, out of which 34 (18.68%) were positive for dengue-specific IgM antibodies. Significantly, all the positive cases were detected during the months of September to November. Retro-orbital pain was present in a significantly more number of IgM-positive cases as compared to IgM-negative cases. Group 2 included 125 cases without fever. The overall positivity for dengue-specific IgG antibodies was 77.6%, with the highest positivity of 100% in the age group of 31-40 years. It was concluded that dengue virus infection is endemic in and around Delhi with peak incidence between September and Novemver. The prevalent serotype during September and December 1997 was DEN1. Since previous epidemic of DHF was due to DEN2 type, isolation of DEN1 serotype indicates changes of another epidemic of DHF due to DEN1 serotype. The stresses the urgent need for implementation of measures to control the transmission of dengue infection.

Classical polyarteritis nodosa and microscopic polyangiitis--a clinicopathologic study.

OBJECTIVE: To describe the clinical spectrum, laboratory features, histopathological findings and treatment outcome in patients with classical polyarteritis nodosa (PAN) and microscopic polyangiitis (MPA). MATERIAL AND METHODS: Patients with PAN and MPA seen at a large teaching hospital in north India over a period of five years (1994-99) were included in the present study. RESULTS: We encountered five patients with PAN and six patients with MPA during the study period. Of the five patients with PAN, two had systemic disease while three had limited PAN. The patients with limited PAN included two with cutaneous PAN and one with PAN confined to the nerves. Constitutional symptoms, musculoskeletal complaints, peripheral neuropathy and skin lesions dominated the clinical picture. Fifty percent of the MPA patients presented as pulmonary renal syndrome. All the patients with PAN were HBsAg and ANCA negative and had normal urinalysis findings. In contrast, all patients with MPA demonstrated an active urine sediment and 83.3% were pANCA positive. Some of the rare features encountered by us were the presence of antiphospholipid syndrome and extensive interstitial lung disease in MPA, and spontaneous recovery in one patient with systemic PAN. Treatment outcome was better in PAN as compared with MPA. CONCLUSIONS: The clinical spectrum of PAN and MPA is quite varied. A good outcome is possible with the use of corticosteroids and cyclophosphamide.

Doxycycline in the treatment of rheumatoid arthritis--a pilot study.

OBJECTIVE: To assess the efficacy and safety of doxycycline as a disease modifying anti-rheumatic drug (DMARD) in rheumatoid arthritis (RA) and compare it with methotrexate, a standard DMARD. MATERIAL AND METHODS: A single (assessor) blind prospective study with 15 patients of RA randomized to doxycycline and 14 to methotrexate. Baseline disease characteristics were similar in both groups. RESULTS: All disease activity measures studied viz. tender and swollen joint counts, physician and patient global assessment, visual analogue pain scale, health assessment questionnaire and ESR improved in both the treatment groups after six months of treatment. The difference between doxycycline and methotrexate was not statistically significant. No major side effects necessitating drug withdrawal were reported from either group. The side effects were few and mostly gastrointestinal. CONCLUSION: Doxycycline is a safe disease modifying drug in RA whose effect is sustained at six months. It compared favourably with methotrexate over a six month follow up.
